Can you buy viagra online

In early March, when erectile dysfunction can you buy viagra online testing was still scarce, Maggie Flannery, a Manhattan sixth-grader, and both her parents fell ill with the symptoms of erectile dysfunction treatment. After three can you buy viagra online weeks, her parents recovered. Maggie also seemed to get better, but only briefly before suffering a relapse that left her debilitated.“It felt like an elephant sitting on my chest,” Maggie said. €œIt was hard to take a deep breath, I was nauseous all the time, I didn’t want to eat, I was very light-headed when I stood up or even just lying down.” She also experienced joint pain and severe fatigue.At first, specialists suggested Maggie’s symptoms can you buy viagra online might be psychological, in part because she showed no sign of heart or lung damage.

She also tested negative for both the erectile dysfunction itself and for antibodies to it. But viral tests taken long after the initial are generally negative, can you buy viagra online and antibody tests are frequently inaccurate.“They didn’t know anything about ‘long-erectile dysfunction treatment’ at that point,” said Amy Wilson, Maggie’s mother. €œThey said it was anxiety. I was can you buy viagra online pretty sure that wasn’t true.”Maggie’s pediatrician, Dr.

Amy DeMattia, has since confirmed the erectile dysfunction treatment diagnosis, based on the child’s clinical history and the fact that both her parents tested positive for erectile dysfunction antibodies.More than seven months into the erectile dysfunction viagra, it has become increasingly apparent that many patients with both severe and mild illness do not fully recover. Weeks and months can you buy viagra online after exposure, these erectile dysfunction treatment “long-haulers,” as they have been called, continue experiencing a range of symptoms, including exhaustion, dizziness, shortness of breath and cognitive impairments. Children are generally at significantly less risk than older people for serious complications and death from erectile dysfunction treatment, but the long-term impacts of on them, if any, have been especially unclear.Although doctors recognize that a small number of children have suffered a rare inflammatory syndrome shortly after , there is little reliable information about how many who get erectile dysfunction treatment have prolonged complaints like Maggie Flannery. That could change as the proportion of can you buy viagra online children who are infected rises.According to the American Academy of Pediatrics, children represented 10.9 percent of reported cases nationwide as of mid-October, up from just 2.2 percent in April.Dr.

Richard Besser, a pediatrician and chief executive of the Robert Wood Johnson Foundation, which focuses on health policy, said parents can be reassured by the data on children’s reduced overall risk. But he noted can you buy viagra online that much remains unknown about erectile dysfunction and its medical consequences, including among children, and that continued vigilance is warranted.“With schools reopening, we’re likely to see more s in children,” he said. €œWe need to make sure we’re doing the studies to understand the short, medium and long-term effects.”To manage her condition, Maggie, who is 12, must limit her activities. Although she has been able to attend socially distanced in-person can you buy viagra online classes at her small private school on the Upper West Side, she no longer walks the 15 blocks there and back.

She has trouble concentrating, so homework takes a lot longer. She has stopped can you buy viagra online attending online ballet classes. Before the viagra, she went to four ballet classes a week.“Some days are a lot better than others,” said Maggie. €œIf I do too much on the good days, I feel a lot worse can you buy viagra online on the next day or next couple of days, and some days I can’t do anything if it’s a bad day.” She has felt a slight improvement over time, she said.Maggie with her mother, Amy Wilson.

€œThey didn’t know anything about ‘long-erectile dysfunction treatment’ at that point,” said Ms. Wilson. €œThey said it was anxiety. I was pretty sure that wasn’t true.”Credit...Brittainy Newman for The New York TimesAs with Maggie, 19-year-old Chris Wilhelm and his parents got sick around the same time.

In their case, it was in June, when viral tests were more available. All three of them tested positive. Only Chris, a rising sophomore at Johns Hopkins and a member of the cross-country and track and field teams, did not get better.Since he did not initially know about the possibility of chronic symptoms, Chris said, he was “confused” and “shocked” about his condition. The first doctors he consulted told him the symptoms would fade, he said.“For a while it was just, ‘We need to wait a bit longer, it will just get better with time,’” he said.

€œEveryone was giving me this magic number, like the 12-week mark is when all your respiratory issues are supposed to go away. We hit that weeks ago, and there’s really not any improvement.”Chris recently consulted with Dr. Peter Rowe, a professor of pediatrics at Johns Hopkins who specializes in chronic and debilitating conditions like myalgic encephalomyelitis/chronic fatigue syndrome, which is often triggered by a viral illness and has no approved drug treatments. Dr.

Rowe determined that Chris has the heart-racing condition known as postural orthostatic tachycardia syndrome, or POTS, which can occur after viral s and limits the ability to carry out day-to-day activities.“He had been capable of training 60 and 70 miles a week as a runner,” said Dr. Rowe, adding that some of the symptoms and the “really severe impairment” that Chris and many other long-haulers suffer from are characteristic of ME/CFS.Under Dr. Rowe’s direction, Chris has been trying different medications in an effort to alleviate the symptoms.In Baltimore, the Kennedy Krieger Institute, a treatment facility for children with neurological and other chronic disabilities, is offering multidisciplinary services for those under 21 who continue to experience challenges after erectile dysfunction treatment. So far the institute has seen only one patient, said Dr.

Melissa Trovato, the institute’s interim medical director of rehabilitation.With s on the rise, Dr. Trovato said she thought it was “quite possible” the clinic will see more patients with persistent symptoms in the coming months. Because of the perception that erectile dysfunction treatment is rare in kids, she said, parents might not associate a mild illness and subsequent effects, like a loss of energy, with the erectile dysfunction.“It might take more time for family to pick up on it,” she said. €œFrom a pediatric perspective there probably is more that we’re going to find out, as more children” with “prolonged symptoms come forward and get seen.”Ziah McKinney-Taylor, a dancer and birth doula in Atlanta, never doubted that her 14-year-old daughter, Ava, was suffering from the lingering effects of erectile dysfunction treatment, even though she tested negative for both the viagra and antibodies.

Before Ava got sick in March, said Ms. McKinney-Taylor, she was a “super-energetic kid” who took dancing and aikido lessons five days a week. That has changed. €œShe has never really gotten her energy back, she is always sleeping and napping,” she said.Ava herself rejected as “ridiculous” the suggestion from some doctors that her exhaustion might be related to the stresses of life under quarantine.

€œLike, ‘You’re just not getting to do your normal activities,’” she said. €œI’m a very active person, this couldn’t just be, ‘Oh, I’m sad that my friends are gone.’”Like other families confronting similar uncertainties, Ms. McKinney-Taylor and her daughter are feeling their way forward amid the unknowns of the disease. €œIt is very scary as a parent to not know how to prepare yourself and protect your child, other than read lots of articles and be on a Slack group,” she said, referring to the Body Politic erectile dysfunction treatment online support community.Under the circumstances, Ava said it can be tough to maintain her spirits.

€œIt’s a little hard to have hope right now,” she said. €œWe don’t know if this will be a lifelong thing, if this will last a year, or two years or five years. So the future is not looking too bright for me personally.”Could running actually be good for your knees?. That idea is at the heart of a fascinating new study of the differing effects of running and walking on the knee joint.

Using motion capture and sophisticated computer modeling, the study confirms that running pummels knees more than walking does. But in the process, the authors conclude, running likely also fortifies and bulks up the cartilage, the rubbery tissue that cushions the ends of bones. The findings raise the beguiling possibility that, instead of harming knees, running might fortify them and help to stave off knee arthritis.Of course, the notion that running wrecks knees is widespread and entrenched. Almost anyone who runs is familiar with warnings from well-meaning, nonrunning family members, friends and strangers that their knees are doomed.This concern is not unwarranted.

Running involves substantial joint bending and pounding, which can fray the cushioning cartilage inside the knee. Cartilage, which does not have its own blood supply, generally is thought to have little ability to repair itself when damaged or to change much at all after childhood. So, repeated running conceivably wears away fragile cartilage and almost inevitably should lead to crippling knee arthritis.But in real life, it does not. Some runners develop knee arthritis, but not all.

As a group, in fact, runners may be statistically less likely to become arthritic than nonrunners.The question of why running spares so many runners’ knees has long intrigued Ross Miller, an associate professor of kinesiology at the University of Maryland in College Park. In earlier research, he and his colleagues had looked into whether running mechanics matter, by asking volunteers to walk and run along a track outfitted with plates to measure the forces generated with each step.The resulting data showed that people hit the ground harder while running, clobbering their knees far more with each stride. But they also spent more time aloft between strides, meaning they took fewer strides while covering the same distance as when walking. So, the cumulative forces moving through their knees over time should be about the same, the researchers concluded, whether someone walked or ran.But, recently, Dr.

Miller had begun to doubt whether this finding really explained why running wasn’t wrecking more knees. He knew that some recent studies with animals intimated that cartilage might be more resilient than researchers previously had believed. In those studies, animals that ran tended to have thicker, healthier knee cartilage than comparable tissues from sedentary animals, suggesting that the active animals’ cartilage had changed in response to their running.Perhaps, Dr. Miller speculated, cartilage in human runners’ knees likewise might alter and adapt.To find out, he again asked a group of healthy young men and women to walk and run along a track containing force plates, while he and his colleagues filmed them.

The researchers then computed the forces the volunteers had generated while strolling and running. Finally, they modeled what the future might hold for the volunteers’ knees.More specifically, they used the force-plate numbers, plus extensive additional data from past studies of biopsied cartilage pulled and pummeled in the lab until it fell apart and other sources to create computer simulations. They wanted to see what, theoretically, would happen to healthy knee cartilage if an adult walked for six kilometers (about 3.7 miles) every day for years, compared to if they walked for three kilometers and ran for another three kilometers each of those days.They also tested two additional theoretical situations. For one, the researchers programmed in the possibility that people’s knee cartilage would slightly repair itself after repeated small damage from walking or running — but not otherwise change.

And for the last scenario, they presumed that the cartilage would actively remodel itself and adapt to the demands of moving, growing thicker and stronger, much as muscle does when we exercise.The models’ final results were eye-opening. According to the simulations, daily walkers faced about a 36 percent chance of developing arthritis by the age of 55, if the model did not include the possibility of the knee cartilage adapting or repairing itself. That risk dropped to about 13 percent if cartilage were assumed to be able to repair or adapt, which is about what studies predict to be the real-world arthritis risk for otherwise healthy people.The numbers for running were more worrisome. When the model assumed cartilage cannot change, the runners’ risk of eventual arthritis was a whopping 98 percent, declining only to 95 percent if the model factored in the possibility of cartilage repair.

In effect, according to this scenario, the damage to cartilage from frequent running would overwhelm any ability of the tissue to fix itself.But if the model included the likelihood of the cartilage actively adapting — growing thicker and cushier — when people ran, the odds of runners developing arthritis fell to about 13 percent, the same as for healthy walkers.What these results suggest is that cartilage is malleable, Dr. Ross says. It must be able to sense the strains and slight damage from running and rebuild itself, becoming stronger. In this scenario, running bolsters cartilage health.Modeled results like these are theoretical, though, and limited.

They do not explain how cartilage remodels itself without a blood supply or if genetics, nutrition, body weight, knee injuries and other factors affect individual arthritis risks. Such models also do not tell us if different distances, speeds or running forms would alter the outcomes. To learn more, we will need direct measures of molecular and other changes in living human cartilage after running, Dr. Miller says, but such tests are difficult.Still, this study may quiet some runners’ qualms — and those of their families and friends.

€œIt looks like running is unlikely to cause knee arthritis by wearing out cartilage,” Dr. Ross says..

What is Viagra?

Generic Viagra is used to treat male Impotence also known as Erectile Dysfunction. Also, it has been approved by US FDA for treating pulmonary arterial hypertension.

What i should buy with viagra

Elon Musk on Friday unveiled a coin-sized prototype of a brain implant developed by his startup Neuralink to enable people who are paralyzed to operate smartphones and robotic limbs with their thoughts — and said the company had worked to “dramatically simplify” the device since presenting an earlier version http://omalandro.com/?page_id=17 last summer.In an event live-streamed on YouTube to more than 150,000 viewers at one point, the company staged a demonstration in which it trotted out a pig named Gertrude that was said to what i should buy with viagra have had the company’s device implanted in its head two months ago. The live stream showed what Musk claimed to be Gertrude’s real-time brain activity as it sniffed around a pen. At no point, though, did he provide evidence that the signals — rendered in beeps and bright blue wave patterns on screen — what i should buy with viagra were, in fact, emanating from the pig’s brain.A pig presented at a Neuralink demonstration was said to have one of the company’s brain implants in its head.

YouTube screenshot“This is obviously sounding increasingly like a Black Mirror episode,” Musk said at one point during the event as he responded affirmatively to a question about whether the company’s implant could eventually be used to save and replay memories. €œThe future’s going to be weird.”advertisement Musk said what i should buy with viagra that in July Neuralink received a breakthrough device designation from the Food and Drug Administration — a regulatory pathway that could allow the company to soon start a clinical trial in people with paraplegia and tetraplegia. The big reveal came after four former Neuralink employees told STAT that the company’s leaders have long fostered an internal culture characterized by rushed timelines and the “move fast and break things” ethos of a tech company — a pace sometimes at odds with the slow and incremental pace that’s typical of medical device development.

Advertisement Friday’s event began, 40 minutes late, with a glossy video about the company’s work — and then panned to Musk, standing in front of a blue curtain beside a gleaming new version of the company’s surgical “sewing machine” robot what i should buy with viagra that could easily have been mistaken for a giant Apple device. Musk described the event as a “product demo” and said its primary purpose was to recruit potential new employees. It was unclear whether the demonstration was taking place at the company’s Fremont, Calif., headquarters what i should buy with viagra or elsewhere.

Musk proceeded to reveal the new version of Neuralink’s brain implant, which he said was designed to fit snugly into the top of the skull. Neuralink’s technological design has changed significantly since its last big update what i should buy with viagra in July 2019. At that time, the company’s brain implant system involved a credit-card sized device designed to be positioned behind the back of a person’s ear, with several wires stretching to the top of the skull.

After demonstrating the pig’s brain activity at Friday’s event, Musk showed video footage of a pig walking on a treadmill and said Neuralink’s device could be used to “predict the position of limbs with high what i should buy with viagra accuracy.” That capability would be critical to allowing someone using the device to do something like controlling a prosthetic limb, for example.Neuralink for months has signaled that it initially plans to develop its device for people who are paralyzed. It said at its July 2019 event that it wanted to start human testing by the end of 2020. Receiving the breakthrough what i should buy with viagra device designation from the FDA — designed to speed up the lengthy regulatory process — is a step forward, but it by no means guarantees that a device will receive a green light, either in a short or longer-term time frame.

After Musk’s presentation, a handful of the company’s employees — all wearing masks, but seated only inches apart — joined him to take questions submitted on Twitter or from the small audience in the room.In typical fashion for a man who in 2018 sent a Tesla Roadster into space, Musk didn’t hesitate to use the event to cross-promote his electric car company. Asked whether the Neuralink chip what i should buy with viagra would allow people to summon their Tesla telepathically, Musk responded. €œDefinitely — of course.”Matthew MacDougall, the company’s head neurosurgeon, appearing in scrubs, said the company had so far only implanted its technology into the brain’s cortical surface, the coaster-width layer enveloping the brain, but added that it hoped to go deeper in the future.

Still, Musk said what i should buy with viagra. €œYou could solve blindness, you could solve paralysis, you could solve hearing — you can solve a lot just by interfacing with the cortex.”Musk and MacDougall said they hoped to eventually implant Neuralink’s devices — which they referred to on stage simply as “links” — in the deeper structures of the brain, such as in the hypothalamus, which is believed to play a critical role in mental illnesses including depression, anxiety, and PTSD.There were no updates at the event of Neuralink’s research in monkeys, which the company has been conducting in partnership with the University of California, Davis since 2017. At last July’s event, Musk what i should buy with viagra said — without providing evidence — that a monkey had controlled a computer with its brain.At that same July 2019 event, Neuralink released a preprint paper — published a few months later — that claimed to show that a series of Neuralink electrodes implanted in the brains of rats could record neural signals.

Critically, the work did not show where in the brain the implanted electrodes were recording from, for how long they were recording, or whether the recordings could be linked to any of the rats’ bodily movements.In touting Friday’s event — and Neuralink’s technological capabilities — on Twitter in recent weeks, Musk spoke of “AI symbiosis while u wait” and referenced the “matrix in the matrix” — a science-fiction reference about revealing the true nature of reality. The progress the what i should buy with viagra company reported on Friday fell far short of that. Neuralink’s prototype is ambitious, but it has yet to show evidence that it can match up to the brain-machine interfaces developed by academic labs and other companies.

Other groups have shown that they can listen in on neural activity and allow primates and people to control a computer cursor with their brain — so-called “read-out” technology — and have also shown that they can use electrical stimulation to what i should buy with viagra input information, such as a command or the heat of a hot cup of coffee, using “write-in” technology. Neuralink said on Friday that its technology would have both read-out and write-in capabilities.Musk acknowledged that Neuralink still has a long way to go. In closing the event after what i should buy with viagra more than 70 minutes, Musk said.

€œThere’s a tremendous amount of work to be done to go from here to a device that is widely available and affordable and reliable.”Following the news this week of what appears to have been the first confirmed case of a erectile dysfunction treatment re, other researchers have been coming forward with their own reports. One in Belgium, another in the Netherlands. And now, one in Nevada.What caught experts’ attention about the case of the 25-year-old Reno man was not what i should buy with viagra that he appears to have contracted erectile dysfunction (the name of the viagra that causes erectile dysfunction treatment) a second time.

Rather, it’s that his second bout was more serious than his first.Immunologists had expected that if the immune response generated after an initial could not prevent a second case, then it should at least stave off more severe illness. That’s what occurred with the first known re case, in a 33-year-old Hong Kong man.advertisement Still, despite what happened to the man in what i should buy with viagra Nevada, researchers are stressing this is not a sky-is-falling situation or one that should result in firm conclusions. They always presumed people would become vulnerable to erectile dysfunction treatment again some time after recovering from an initial case, based on how our immune systems respond to other respiratory viagraes, including other erectile dysfunctiones.

It’s possible that these early cases of re are outliers and have features what i should buy with viagra that won’t apply to the tens of millions of other people who have already shaken off erectile dysfunction treatment.“There are millions and millions of cases,” said Michael Mina, an epidemiologist at Harvard’s T.H. Chan School of Public Health. The real question that should get the most focus, Mina said, is, “What happens to what i should buy with viagra most people?.

€advertisement But with more re reports likely to make it into the scientific literature soon, and from there into the mainstream press, here are some things to look for in assessing them.What’s the deal with the Nevada case?. The Reno resident in question first tested positive for erectile dysfunction in April after coming down with a sore throat, cough, and headache, as well as nausea and diarrhea what i should buy with viagra. He got better over time and later tested negative twice.

But then, some 48 days later, the man started experiencing what i should buy with viagra headaches, cough, and other symptoms again. Eventually, he became so sick that he had to be hospitalized and was found to have pneumonia.Researchers sequenced viagra samples from both of his s and found they were different, providing evidence that this was a new distinct from the first. What what i should buy with viagra happens when we get erectile dysfunction treatment in the first case?.

Researchers are finding that, generally, people who get erectile dysfunction treatment develop a healthy immune response replete with both antibodies (molecules that can block pathogens from infecting cells) and T cells (which help wipe out the viagra). This is what happens after other what i should buy with viagra viral s.In addition to fending off the viagra the first time, that immune response also creates memories of the viagra, should it try to invade a second time. It’s thought, then, that people who recover from erectile dysfunction treatment will typically be protected from another case for some amount of time.

With other erectile dysfunctiones, protection is thought to last for perhaps a little less than a year what i should buy with viagra to about three years.But researchers can’t tell how long immunity will last with a new pathogen (like erectile dysfunction) until people start getting reinfected. They also don’t know exactly what mechanisms provide protection against erectile dysfunction treatment, nor do they know what levels of antibodies or T cells are required to signal that someone is protected through a blood test. (These are called what i should buy with viagra the “correlates of protection.”) Why do experts expect second cases to be milder?.

With other viagraes, protective immunity doesn’t just vanish one day. Instead, it wanes what i should buy with viagra over time. Researchers have then hypothesized that with erectile dysfunction, perhaps our immune systems might not always be able to prevent it from getting a toehold in our cells — to halt entirely — but that it could still put up enough of a fight to guard us from getting really sick.

Again, this is what happens what i should buy with viagra with other respiratory pathogens.And it’s why some researchers actually looked at the Hong Kong case with relief. The man had mild to moderate erectile dysfunction treatment symptoms during the first case, but was asymptomatic the second time. It was a demonstration, experts said, of what you would want your immune system to what i should buy with viagra do.

(The case was only detected because the man’s sample was taken at the airport when he arrived back in Hong Kong after traveling in Europe.)“The fact that somebody may get reinfected is not surprising,” Malik Peiris, a virologist at the University of Hong Kong, told STAT earlier this week about the first re. €œBut the re didn’t cause disease, so that’s the first point.”The Nevada case, then, provides a counterexample to that. What kind of immune response what i should buy with viagra did the person who was reinfected generate initially?.

Earlier, we described the robust immune response that most people who have erectile dysfunction treatment seem to mount. But that was a generalization what i should buy with viagra. s and the immune responses they induce in different people are “heterogeneous,” said Sarah Cobey, an epidemiologist and evolutionary biologist at the University of Chicago.Older people often generate weaker immune responses than younger people.

Some studies have also indicated that milder cases of erectile dysfunction treatment induce what i should buy with viagra tamer immune responses that might not provide as lasting or as thorough of a defense as stronger immune responses. The man in Hong Kong, for example, did not generate antibodies to the viagra after his first , at least to the level that could be detected by blood tests. Perhaps that explains why he contracted the viagra again just about 4 1/2 months after recovering from his initial .In the Nevada case, researchers did not test what kind of immune response the man generated after the first case.“ what i should buy with viagra is not some binary event,” Cobey said.

And with re, “there’s going to be some viral replication, but the question is how much is the immune system getting engaged?. €What might be broadly meaningful is what i should buy with viagra when people who mounted robust immune responses start getting reinfected, and how severe their second cases are. Are people who have erectile dysfunction treatment a second time infectious?.

As discussed, immune what i should buy with viagra memory can prevent re. If it can’t, it might stave off serious illness. But there’s a third aspect of this, too.“The most what i should buy with viagra important question for re, with the most serious implications for controlling the viagra, is whether reinfected people can transmit the viagra to others,” Columbia University virologist Angela Rasmussen wrote in Slate this week.Unfortunately, neither the Hong Kong nor the Reno studies looked at this question.

But if most people who get reinfected don’t spread the viagra, that’s obviously good news. What happens when what i should buy with viagra people broadly become susceptible again?. Whether it’s six months after the first or nine months or a year or longer, at some point, protection for most people who recover from erectile dysfunction treatment is expected to wane.

And without the arrival of a treatment and broad uptake of it, that could change the dynamics of local outbreaks.In some communities, it’s thought that more than 20% of what i should buy with viagra residents have experienced an initial erectile dysfunction treatment case, and are thus theoretically protected from another case for some time. That is still below the point of herd immunity — when enough people are immune that transmission doesn’t occur — but still, the fewer vulnerable people there are, the less likely spread is to occur.On the flip side though, if more people become susceptible to the viagra again, that could increase the risk of transmission. Modelers are starting to what i should buy with viagra factor that possibility into their forecasts.A crucial question for which there is not an answer yet is whether what happened to the man in Reno, where the second case was more severe than the first, remains a rare occurrence, as researchers expect and hope.

As the Nevada researchers wrote, “the generalizability of this finding is unknown.”An advocacy group has asked the Department of Defense to investigate what it called “an apparent failure” by Moderna (MRNA) to disclose millions of dollars in awards received from the Defense Advanced Research Projects Agency in patent applications the company filed for treatments.In a letter to the agency, Knowledge Ecology International explained that a review of dozens of patent applications found the company received approximately $20 million from the federal government in grants several years ago and the funds “likely” led to the creation of its treatment technology. This was used to develop treatments to combat different viagraes, such as Zika and, later, the viagra that causes erectile dysfunction treatment.In arguing for an investigation, what i should buy with viagra the advocacy group maintained Moderna is obligated under federal law to disclose the grants that led to nearly a dozen specific patent applications and explained the financial support means the U.S. Government would have certain rights over the patents.

The patent names a Moderna scientist and a former Moderna scientist as inventors, both of which acknowledged performing work under the DARPA awards in two academic papers, according to the report by the advocacy group.advertisement The group examined the 126 patents assigned to Moderna or ModernaTx as well as 154 patent applications. €œDespite the evidence that multiple inventions were conceived in the course of research supported by the DARPA awards, not a single one of the patents or applications assigned to Moderna http://www.campus-yspertal.at/kindergarten-yspertal/ disclose U.S. Federal government funding,” the what i should buy with viagra report stated.[UPDATE.

A DARPA spokesman sent us this over the weekend. €œIt appears what i should buy with viagra that all past and present DARPA awards to Moderna include the requirement to report the role of government funding for related inventions. Further, DARPA is actively researching agency awards to Moderna to identify which patents and pending patents, if any at all, may be associated with DARPA support.

This effort is what i should buy with viagra ongoing.”]We asked Moderna for comment and will update you accordingly.The missive to the Department of Defense follows a recent analysis by Public Citizen, another advocacy group, indicating the National Institutes of Health may own mRNA-1273, the Moderna treatment candidate for erectile dysfunction treatment. The advocacy group noted the federal government filed multiple patents covering the treatment and two patent applications, in particular, list federal scientists as co-inventors.The analyses are part of a larger campaign among advocacy groups and others in the U.S. And elsewhere to ensure that erectile dysfunction treatment what i should buy with viagra medical products are available to poor populations around the world.

The concern reflects the unprecedented global demand for therapies and treatments, and a race among wealthy nations to snap up supplies from treatment makers. In the U.S., the effort has focused on the extent what i should buy with viagra to which the federal government has provided taxpayer dollars to different companies to help fund their discoveries. In some cases, advocates argue that federal funding matters because it clarifies the rights that the U.S.

Government has to ensure a therapy or treatment is available to Americans on reasonable terms.One example has what i should buy with viagra been remdesivir, the Gilead Sciences (GILD) treatment being given to hospitalized erectile dysfunction treatment patients. The role played by the U.S. Government in developing remdesivir to combat erectile dysfunctiones involved contributions from government personnel at such agencies as what i should buy with viagra the U.S.

Army Medical Research Institute of Infectious Diseases.As for the Moderna treatment, earlier this month, the company was awarded a $1.525 billion contract by the Department of Defense and the Department of Health and Human Services to manufacture and deliver 100 million doses of its erectile dysfunction treatment. The agreement also includes an option to purchase another 400 million doses, although what i should buy with viagra the terms were not disclosed. In announcing the agreement, the government said it would ensure Americans receive the erectile dysfunction treatment at no cost, although they may be charged by health care providers for administering a shot.In this instance, however, Love said the “letter is not about price or profits.

It’s about (Moderna) not owning what i should buy with viagra up to DARPA funding inventions. If the U.S. Wants to pay for all of the development of Moderna’s treatment, as Moderna now acknowledges, and throw in a few more billion now, and an option to spend billions more, it’s not unreasonable to have some transparency over who paid for their inventions.”This is not the first time Moderna what i should buy with viagra has been accused of insufficient disclosure.

Earlier this month, Knowledge Ecology International and Public Citizen maintained the company failed to disclose development costs in a $955 million contract awarded by BARDA for its erectile dysfunction treatment. In all, the federal government has awarded the company approximately $2.5 billion to develop the treatment.The coming few weeks represent a crucial moment for an ambitious plan to what i should buy with viagra try to secure erectile dysfunction treatments for roughly 170 countries around the world without the deep pockets to compete for what will be scarce initial supplies.Under the plan, countries that want to pool resources to buy treatments must notify the World Health Organization and other organizers — Gavi, the treatment Alliance, as well as the Coalition for Epidemic Preparedness Innovations — of their intentions by Monday. That means it’s fish-or-cut-bait time for the so-called COVAX facility.Already, wealthy countries — the United States, the United Kingdom, Japan, Canada, and Australia, among others, as well as the European Union — have opted to buy their own treatment, signing bilateral contracts with manufacturers that have secured billions of doses of treatment already.

That raises the possibility that less wealthy countries will be boxed out of supplies.advertisement And yet Richard Hatchett, the CEO of CEPI, what i should buy with viagra insists there is a path to billions of doses of treatment for the rest of the world in 2021. STAT spoke with Hatchett this week. A transcript what i should buy with viagra of the conversation, lightly edited for clarity and length, follows.

You said this is a critical time for CEPI. Can you explain what needs to happen between now and mid-September for this joint purchasing approach to be a success?. Advertisement The critical moment is now for countries to commit to the COVAX facility, because that will enable us to secure ample quantities of treatment and then to be able to convey when that treatment is likely to become available based what i should buy with viagra on current information.What we’re now here asking countries to do is to indicate their intent to participate by Aug.

31, and to make a binding commitment by Sept. 18. And to provide funds in support of that binding commitment by early October.

Our negotiations with companies are already taking place and it will be important for us from a planning purpose that countries indicate their intent to participate.Those binding commitments we think will be sufficient to allow us to then secure the advance purchase agreements, particularly with those companies that don’t have a prior contractual obligation to COVAX. And then obviously, we need the funds to live up to those advance purchase agreements.Is it possible this thing could still fall apart?. There appears to be some concern COVAX has been boxed out by rich countries.

There was always a possibility that there wouldn’t be sufficient uptake. But I think we’re very encouraged at this point by the level of commitment, both from countries that would be beneficiaries of the advance market commitment — that’s the lower-income, lower-middle-income countries — as well as the self-financing countries. To have over 170 countries expressing interest in participating — they see the value.We’re much more encouraged now that it’s not going to fall apart.

We still need to bring it off to maximize its value. And we’re right at the crunch moment where countries are going to have to make these commitments. So, the next month is really absolutely critical to the facility.

I am confident at this point that the world recognizes the value and wants it to work.I’ve been keeping tabs on advance purchase agreements that have been announced. And at this point, a small number of rich countries have nailed down a lot of treatment — more than 3 billion doses. How hard does that make your job?.

The fact that they’re doing it creates anxiety among other countries. And that in itself can accelerate the pace. So, I’m not going to say that we’re not watching that with concern.I will say that for COVAX and the facility, this is absolutely critical moment.

I think we still have a window of opportunity between now and mid-September — when we’re asking that the self-financing countries to make their commitments — to make the facility real and to make it work. Between doses that are committed to COVAX through the access agreements and other agreements — these are discussions with partners that CEPI has funded as well as partners that CEPI has not funded — we still see a pathway for COVAX to well over 3 billion doses in 2021.I think it’s really important to bear in mind is that there are at least a few countries — and I think the U.S. And the U.K.

Most publicly — that may be in a situation of significant oversupply. I believe the U.S. And U.K.

Numbers, if you add them together, would result in enough treatment for 600 million people to receive two doses of treatment each. And, you know, there is no possible way that the U.S. Or the U.K.

Can use that much treatment.So, there may be a lot of extra supply that looks like it’s been tied up sloshing around later. I don’t think that the bilateral deals that have been struck are going to prevent COVAX from achieving its goals.But if so much treatment has been pre-ordered by rich countries, can countries in the COVAX pool get enough for their needs?. One of the things that we’ve argued through COVAX is that to control the viagra or to end the acute phase of the viagra to allow normalcy to start to reassert itself, you don’t have to vaccinate 100% of your population.You need to vaccinate those at greatest risk for bad outcomes and you need to vaccinate certain critical workers, particularly your health care workforce.

And if you can achieve that goal, which for most countries means vaccinating between 20% and maybe 30% of the population, then you can transform the viagra into something that is much more manageable. Then you can buy yourself time to vaccinate everybody who wants to be vaccinated.We’ve argued the COVAX facility really offers the world the best shot at doing that globally in the fastest possible way, as well as providing for equitable access. This is a case where doing the equitable thing is also doing the efficient thing.CEPI has provided funding to nine treatments.

Is it true that all those manufacturers aren’t required to provide the COVAX facility with treatment?. That is correct. One of the things that we did, and I think it was an important role that CEPI played early on, was that we moved money very, very quickly, in small increments.

You know, some of the early contracts were only $5 million or $10 million, to get programs up and running while we potentially put in place much larger-scale, longer-term contracts.If you were doing it over again, would you have given money without strings attached?. Yes, I think I would have. I think that was critically important to initiating programs.Our contract with Moderna was established in about 48 hours.

And that provided critical funding to them to manufacture doses that got them into clinical trials within nine weeks of the genetic sequences [of the erectile dysfunction viagra] being released.And if you look at the nine programs that we’ve invested in, seven are in clinical trials. Two — the AstraZeneca program now and the Moderna program — are among the handful in Phase 3 clinical trials. And, I think the number of projects that that we funded initially, which started in kind of a biotech or academic phase that have now been picked up by large multinational corporations, there’s at least four.

The Themis program being picked up by Merck, Oxford University by AstraZeneca, the University of Queensland by CSL, and Clover being in partnership with GSK, I think that speaks to the quality of the programs that we selected.So, I think that combination of rapid review, speed of funding, getting those programs started, getting them oriented in the right direction, I think all of that is critical to where we are now.Companies that got money from CEPI to build out production capacity — that money came with strings attached, right?. Yes, exactly. So, where CEPI has made investments that create manufacturing, or secure manufacturing capacity, the commitment has been that the capacity that is attributable to the CEPI investment is committed — at least right of first refusal — to the global procurement facility.WASHINGTON — The Trump administration removed a top Food and Drug Administration communications official from her post on Friday in the wake of several controversial agency misstatements, a senior administration official confirmed to STAT.The spokeswoman, Emily Miller, had played a lead role in defending the FDA commissioner, Stephen Hahn, after he misrepresented data regarding the use of blood plasma from recovered erectile dysfunction treatment patients.

The New York Times first reported Miller’s ouster. Miller’s tenure at as the top FDA spokeswoman lasted only 11 days. Her appointment was viewed with alarm by agency officials who felt her presence at the agency was emblematic of broader political pressure from the Trump administration, STAT first reported earlier this week.advertisement Before joining the FDA, Miller had no experience in health or medicine.

Her former role as assistant commissioner for media affairs is typically not an appointment filled by political appointees. The FDA’s communications arm typically maintains a neutral, nonpolitical tone.Miller’s appointment particularly alarmed FDA staff and outside scientists given her history in right-wing political advocacy and conservatism journalism. Her résumé included a stint as a Washington Times columnist, where she penned columns with titles that include “New Obamacare ads make young women look like sluts,” and a 2013 book on gun rights titled “Emily Gets Her Gun.

But Obama Wants to Take Yours.”advertisement She also worked as a reporter for One America News Network, a right-wing cable channel that frequently espouses conspiracy theories and has declared an open alliance with President Trump.Miller quickly made her presence known at the FDA. In the wake of Hahn’s misstatements on blood plasma, she aggressively defended the commissioner, falsely claiming in a tweet that the therapy “has shown to be beneficial for 35% of patients.” An FDA press release on blood plasma, issued less than a week after her appointment, similarly alarmed agency insiders by trumpeting the emergency authorization as “Another Achievement in Administration’s Fight Against [the] viagra.”.

Elon Musk on Friday unveiled a coin-sized prototype of a brain implant developed by his startup Neuralink to enable people who are paralyzed to operate smartphones and robotic limbs with their thoughts — and said the company had worked to “dramatically simplify” the device since presenting where to buy generic viagra an earlier version last summer.In an event live-streamed on YouTube to more than 150,000 viewers at one point, the company can you buy viagra online staged a demonstration in which it trotted out a pig named Gertrude that was said to have had the company’s device implanted in its head two months ago. The live stream showed what Musk claimed to be Gertrude’s real-time brain activity as it sniffed around a pen. At no point, though, did he provide evidence that the signals — can you buy viagra online rendered in beeps and bright blue wave patterns on screen — were, in fact, emanating from the pig’s brain.A pig presented at a Neuralink demonstration was said to have one of the company’s brain implants in its head. YouTube screenshot“This is obviously sounding increasingly like a Black Mirror episode,” Musk said at one point during the event as he responded affirmatively to a question about whether the company’s implant could eventually be used to save and replay memories.

€œThe future’s going to be weird.”advertisement Musk said that can you buy viagra online in July Neuralink received a breakthrough device designation from the Food and Drug Administration — a regulatory pathway that could allow the company to soon start a clinical trial in people with paraplegia and tetraplegia. The big reveal came after four former Neuralink employees told STAT that the company’s leaders have long fostered an internal culture characterized by rushed timelines and the “move fast and break things” ethos of a tech company — a pace sometimes at odds with the slow and incremental pace that’s typical of medical device development. Advertisement Friday’s event began, 40 minutes late, with a glossy video about the company’s work — and then panned to Musk, standing in front of a blue curtain beside a gleaming new version of the company’s surgical “sewing machine” robot that could easily have been mistaken for can you buy viagra online a giant Apple device. Musk described the event as a “product demo” and said its primary purpose was to recruit potential new employees.

It was unclear whether the demonstration was taking place at the can you buy viagra online company’s Fremont, Calif., headquarters or elsewhere. Musk proceeded to reveal the new version of Neuralink’s brain implant, which he said was designed to fit snugly into the top of the skull. Neuralink’s technological design has changed significantly since its last big update in July can you buy viagra online 2019. At that time, the company’s brain implant system involved a credit-card sized device designed to be positioned behind the back of a person’s ear, with several wires stretching to the top of the skull.

After demonstrating the pig’s brain activity at Friday’s event, Musk showed video footage of a pig walking on a treadmill and said Neuralink’s device could be used to “predict the position can you buy viagra online of limbs with high accuracy.” That capability would be critical to allowing someone using the device to do something like controlling a prosthetic limb, for example.Neuralink for months has signaled that it initially plans to develop its device for people who are paralyzed. It said at its July 2019 event that it wanted to start human testing by the end of 2020. Receiving the breakthrough device designation from the FDA — designed to speed up the lengthy regulatory process — is a step forward, but it by no means guarantees that a device will receive a green light, either in can you buy viagra online a short or longer-term time frame. After Musk’s presentation, a handful of the company’s employees — all wearing masks, but seated only inches apart — joined him to take questions submitted on Twitter or from the small audience in the room.In typical fashion for a man who in 2018 sent a Tesla Roadster into space, Musk didn’t hesitate to use the event to cross-promote his electric car company.

Asked whether the Neuralink chip would allow people to summon their can you buy viagra online Tesla telepathically, Musk responded. €œDefinitely — of course.”Matthew MacDougall, the company’s head neurosurgeon, appearing in scrubs, said the company had so far only implanted its technology into the brain’s cortical surface, the coaster-width layer enveloping the brain, but added that it hoped to go deeper in the future. Still, Musk can you buy viagra online said. €œYou could solve blindness, you could solve paralysis, you could solve hearing — you can solve a lot just by interfacing with the cortex.”Musk and MacDougall said they hoped to eventually implant Neuralink’s devices — which they referred to on stage simply as “links” — in the deeper structures of the brain, such as in the hypothalamus, which is believed to play a critical role in mental illnesses including depression, anxiety, and PTSD.There were no updates at the event of Neuralink’s research in monkeys, which the company has been conducting in partnership with the University of California, Davis since 2017.

At last July’s event, Musk said — without providing evidence — that a monkey had controlled a computer with its brain.At that same July 2019 event, Neuralink released a preprint paper — published a few months later — that claimed to can you buy viagra online show that a series of Neuralink electrodes implanted in the brains of rats could record neural signals. Critically, the work did not show where in the brain the implanted electrodes were recording from, for how long they were recording, or whether the recordings could be linked to any of the rats’ bodily movements.In touting Friday’s event — and Neuralink’s technological capabilities — on Twitter in recent weeks, Musk spoke of “AI symbiosis while u wait” and referenced the “matrix in the matrix” — a science-fiction reference about revealing the true nature of reality. The progress can you buy viagra online the company reported on Friday fell far short of that. Neuralink’s prototype is ambitious, but it has yet to show evidence that it can match up to the brain-machine interfaces developed by academic labs and other companies.

Other groups have shown that they can listen in on neural activity and allow primates and people to control a computer cursor with their brain — so-called can you buy viagra online “read-out” technology — and have also shown that they can use electrical stimulation to input information, such as a command or the heat of a hot cup of coffee, using “write-in” technology. Neuralink said on Friday that its technology would have both read-out and write-in capabilities.Musk acknowledged that Neuralink still has a long way to go. In closing the event after more than 70 minutes, Musk said can you buy viagra online. €œThere’s a tremendous amount of work to be done to go from here to a device that is widely available and affordable and reliable.”Following the news this week of what appears to have been the first confirmed case of a erectile dysfunction treatment re, other researchers have been coming forward with their own reports.

One in Belgium, another in the Netherlands. And now, one in Nevada.What caught experts’ attention can you buy viagra online about the case of the 25-year-old Reno man was not that he appears to have contracted erectile dysfunction (the name of the viagra that causes erectile dysfunction treatment) a second time. Rather, it’s that his second bout was more serious than his first.Immunologists had expected that if the immune response generated after an initial could not prevent a second case, then it should at least stave off more severe illness. That’s what occurred with the first known re case, in a 33-year-old Hong Kong man.advertisement Still, despite what happened to the man in Nevada, researchers are stressing this is not a sky-is-falling situation or one that should can you buy viagra online result in firm conclusions.

They always presumed people would become vulnerable to erectile dysfunction treatment again some time after recovering from an initial case, based on how our immune systems respond to other respiratory viagraes, including other erectile dysfunctiones. It’s possible that these early cases of re are outliers and have features that won’t apply to the tens of millions of other people who have already shaken off erectile dysfunction treatment.“There are millions can you buy viagra online and millions of cases,” said Michael Mina, an epidemiologist at Harvard’s T.H. Chan School of Public Health. The real question that should get the most focus, Mina said, is, “What happens can you buy viagra online to most people?.

€advertisement But with more re reports likely to make it into the scientific literature soon, and from there into the mainstream press, here are some things to look for in assessing them.What’s the deal with the Nevada case?. The Reno resident in question first can you buy viagra online tested positive for erectile dysfunction in April after coming down with a sore throat, cough, and headache, as well as nausea and diarrhea. He got better over time and later tested negative twice. But then, some 48 days later, the man started experiencing can you buy viagra online headaches, cough, and other symptoms again.

Eventually, he became so sick that he had to be hospitalized and was found to have pneumonia.Researchers sequenced viagra samples from both of his s and found they were different, providing evidence that this was a new distinct from the first. What happens when we get can you buy viagra online erectile dysfunction treatment in the first case?. Researchers are finding that, generally, people who get erectile dysfunction treatment develop a healthy immune response replete with both antibodies (molecules that can block pathogens from infecting cells) and T cells (which help wipe out the viagra). This is can you buy viagra online what happens after other viral s.In addition to fending off the viagra the first time, that immune response also creates memories of the viagra, should it try to invade a second time.

It’s thought, then, that people who recover from erectile dysfunction treatment will typically be protected from another case for some amount of time. With other erectile dysfunctiones, protection is thought to last for can you buy viagra online perhaps a little less than a year to about three years.But researchers can’t tell how long immunity will last with a new pathogen (like erectile dysfunction) until people start getting reinfected. They also don’t know exactly what mechanisms provide protection against erectile dysfunction treatment, nor do they know what levels of antibodies or T cells are required to signal that someone is protected through a blood test. (These are called the “correlates of protection.”) Why do experts can you buy viagra online expect second cases to be milder?.

With other viagraes, protective immunity doesn’t just vanish one day. Instead, it can you buy viagra online wanes over time. Researchers have then hypothesized that with erectile dysfunction, perhaps our immune systems might not always be able to prevent it from getting a toehold in our cells — to halt entirely — but that it could still put up enough of a fight to guard us from getting really sick. Again, this is what happens with other respiratory pathogens.And it’s why some can you buy viagra online researchers actually looked at the Hong Kong case with relief.

The man had mild to moderate erectile dysfunction treatment symptoms during the first case, but was asymptomatic the second time. It was a demonstration, experts said, of what you would want your immune system to can you buy viagra online do. (The case was only detected because the man’s sample was taken at the airport when he arrived back in Hong Kong after traveling in Europe.)“The fact that somebody may get reinfected is not surprising,” Malik Peiris, a virologist at the University of Hong Kong, told STAT earlier this week about the first re. €œBut the re didn’t cause disease, so that’s the first point.”The Nevada case, then, provides a counterexample to that.

What kind of immune response did can you buy viagra online the person who was reinfected generate initially?. Earlier, we described the robust immune response that most people who have erectile dysfunction treatment seem to mount. But that can you buy viagra online was a generalization. s and the immune responses they induce in different people are “heterogeneous,” said Sarah Cobey, an epidemiologist and evolutionary biologist at the University of Chicago.Older people often generate weaker immune responses than younger people.

Some studies have also indicated that milder cases of erectile dysfunction treatment induce tamer immune responses that might not provide as lasting or as thorough of a defense as stronger immune responses can you buy viagra online. The man in Hong Kong, for example, did not generate antibodies to the viagra after his first , at least to the level that could be detected by blood tests. Perhaps that can you buy viagra online explains why he contracted the viagra again just about 4 1/2 months after recovering from his initial .In the Nevada case, researchers did not test what kind of immune response the man generated after the first case.“ is not some binary event,” Cobey said. And with re, “there’s going to be some viral replication, but the question is how much is the immune system getting engaged?.

€What might be broadly meaningful is when people who mounted robust can you buy viagra online immune responses start getting reinfected, and how severe their second cases are. Are people who have erectile dysfunction treatment a second time infectious?. As discussed, immune can you buy viagra online memory can prevent re. If it can’t, it might stave off serious illness.

But there’s can you buy viagra online a third aspect of this, too.“The most important question for re, with the most serious implications for controlling the viagra, is whether reinfected people can transmit the viagra to others,” Columbia University virologist Angela Rasmussen wrote in Slate this week.Unfortunately, neither the Hong Kong nor the Reno studies looked at this question. But if most people who get reinfected don’t spread the viagra, that’s obviously good news. What happens when people broadly become susceptible can you buy viagra online again?. Whether it’s six months after the first or nine months or a year or longer, at some point, protection for most people who recover from erectile dysfunction treatment is expected to wane.

And without the arrival of a treatment and broad uptake of it, that could change the dynamics of local outbreaks.In can you buy viagra online some communities, it’s thought that more than 20% of residents have experienced an initial erectile dysfunction treatment case, and are thus theoretically protected from another case for some time. That is still below the point of herd immunity — when enough people are immune that transmission doesn’t occur — but still, the fewer vulnerable people there are, the less likely spread is to occur.On the flip side though, if more people become susceptible to the viagra again, that could increase the risk of transmission. Modelers are starting to can you buy viagra online factor that possibility into their forecasts.A crucial question for which there is not an answer yet is whether what happened to the man in Reno, where the second case was more severe than the first, remains a rare occurrence, as researchers expect and hope. As the Nevada researchers wrote, “the generalizability of this finding is unknown.”An advocacy group has asked the Department of Defense to investigate what it called “an apparent failure” by Moderna (MRNA) to disclose millions of dollars in awards received from the Defense Advanced Research Projects Agency in patent applications the company filed for treatments.In a letter to the agency, Knowledge Ecology International explained that a review of dozens of patent applications found the company received approximately $20 million from the federal government in grants several years ago and the funds “likely” led to the creation of its treatment technology.

STAT spoke with Hatchett this week. A transcript of the conversation, can you buy viagra online lightly edited for clarity and length, follows.

You said this is a critical time for CEPI. Can you explain what needs to happen between now and mid-September for this joint purchasing approach to be a success?. Advertisement The critical moment is now for countries to commit to the COVAX facility, because that will enable us to secure ample quantities of can you buy viagra online treatment and then to be able to convey when that treatment is likely to become available based on current information.What we’re now here asking countries to do is to indicate their intent to participate by Aug. 31, and to make a binding commitment by Sept.

18. And to provide funds in support of that binding commitment by early October. Our negotiations with companies are already taking place and it will be important for us from a planning purpose that countries indicate their intent to participate.Those binding commitments we think will be sufficient to allow us to then secure the advance purchase agreements, particularly with those companies that don’t have a prior contractual obligation to COVAX. And then obviously, we need the funds to live up to those advance purchase agreements.Is it possible this thing could still fall apart?.

There appears to be some concern COVAX has been boxed out by rich countries. There was always a possibility that there wouldn’t be sufficient uptake. But I think we’re very encouraged at this point by the level of commitment, both from countries that would be beneficiaries of the advance market commitment — that’s the lower-income, lower-middle-income countries — as well as the self-financing countries. To have over 170 countries expressing interest in participating — they see the value.We’re much more encouraged now that it’s not going to fall apart.

We still need to bring it off to maximize its value. And we’re right at the crunch moment where countries are going to have to make these commitments. So, the next month is really absolutely critical to the facility. I am confident at this point that the world recognizes the value and wants it to work.I’ve been keeping tabs on advance purchase agreements that have been announced.

And at this point, a small number of rich countries have nailed down a lot of treatment — more than 3 billion doses. How hard does that make your job?. The fact that they’re doing it creates anxiety among other countries. And that in itself can accelerate the pace.

So, I’m not going to say that we’re not watching that with concern.I will say that for COVAX and the facility, this is absolutely critical moment. I think we still have a window of opportunity between now and mid-September — when we’re asking that the self-financing countries to make their commitments — to make the facility real and to make it work. Between doses that are committed to COVAX through the access agreements and other agreements — these are discussions with partners that CEPI has funded as well as partners that CEPI has not funded — we still see a pathway for COVAX to well over 3 billion doses in 2021.I think it’s really important to bear in mind is that there are at least a few countries — and I think the U.S. And the U.K.

Most publicly — that may be in a situation of significant oversupply. I believe the U.S. And U.K. Numbers, if you add them together, would result in enough treatment for 600 million people to receive two doses of treatment each.

And, you know, there is no possible way that the U.S. Or the U.K. Can use that much treatment.So, there may be a lot of extra supply that looks like it’s been tied up sloshing around later. I don’t think that the bilateral deals that have been struck are going to prevent COVAX from achieving its goals.But if so much treatment has been pre-ordered by rich countries, can countries in the COVAX pool get enough for their needs?.

One of the things that we’ve argued through COVAX is that to control the viagra or to end the acute phase of the viagra to allow normalcy to start to reassert itself, you don’t have to vaccinate 100% of your population.You need to vaccinate those at greatest risk for bad outcomes and you need to vaccinate certain critical workers, particularly your health care workforce. And if you can achieve that goal, which for most countries means vaccinating between 20% and maybe 30% of the population, then you can transform the viagra into something that is much more manageable. Then you can buy yourself time to vaccinate everybody who wants to be vaccinated.We’ve argued the COVAX facility really offers the world the best shot at doing that globally in the fastest possible way, as well as providing for equitable access. This is a case where doing the equitable thing is also doing the efficient thing.CEPI has provided funding to nine treatments.

Is it true that all those manufacturers aren’t required to provide the COVAX facility with treatment?. That is correct. One of the things that we did, and I think it was an important role that CEPI played early on, was that we moved money very, very quickly, in small increments. You know, some of the early contracts were only $5 million or $10 million, to get programs up and running while we potentially put in place much larger-scale, longer-term contracts.If you were doing it over again, would you have given money without strings attached?.

Yes, I think I would have. I think that was critically important to initiating programs.Our contract with Moderna was established in about 48 hours. And that provided critical funding to them to manufacture doses that got them into clinical trials within nine weeks of the genetic sequences [of the erectile dysfunction viagra] being released.And if you look at the nine programs that we’ve invested in, seven are in clinical trials. Two — the AstraZeneca program now and the Moderna program — are among the handful in Phase 3 clinical trials.

And, I think the number of projects that that we funded initially, which started in kind of a biotech or academic phase that have now been picked up by large multinational corporations, there’s at least four. The Themis program being picked up by Merck, Oxford University by AstraZeneca, the University of Queensland by CSL, and Clover being in partnership with GSK, I think that speaks to the quality of the programs that we selected.So, I think that combination of rapid review, speed of funding, getting those programs started, getting them oriented in the right direction, I think all of that is critical to where we are now.Companies that got money from CEPI to build out production capacity — that money came with strings attached, right?. Yes, exactly. So, where CEPI has made investments that create manufacturing, or secure manufacturing capacity, the commitment has been that the capacity that is attributable to the CEPI investment is committed — at least right of first refusal — to the global procurement facility.WASHINGTON — The Trump administration removed a top Food and Drug Administration communications official from her post on Friday in the wake of several controversial agency misstatements, a senior administration official confirmed to STAT.The spokeswoman, Emily Miller, had played a lead role in defending the FDA commissioner, Stephen Hahn, after he misrepresented data regarding the use of blood plasma from recovered erectile dysfunction treatment patients.

The New York Times first reported Miller’s ouster. Miller’s tenure at as the top FDA spokeswoman lasted only 11 days. Her appointment was viewed with alarm by agency officials who felt her presence at the agency was emblematic of broader political pressure from the Trump administration, STAT first reported earlier this week.advertisement Before joining the FDA, Miller had no experience in health or medicine. Her former role as assistant commissioner for media affairs is typically not an appointment filled by political appointees.

The FDA’s communications arm typically maintains a neutral, nonpolitical tone.Miller’s appointment particularly alarmed FDA staff and outside scientists given her history in right-wing political advocacy and conservatism journalism. Her résumé included a stint as a Washington Times columnist, where she penned columns with titles that include “New Obamacare ads make young women look like sluts,” and a 2013 book on gun rights titled “Emily Gets Her Gun. But Obama Wants to Take Yours.”advertisement She also worked as a reporter for One America News Network, a right-wing cable channel that frequently espouses conspiracy theories and has declared an open alliance with President Trump.Miller quickly made her presence known at the FDA. In the wake of Hahn’s misstatements on blood plasma, she aggressively defended the commissioner, falsely claiming in a tweet that the therapy “has shown to be beneficial for 35% of patients.” An FDA press release on blood plasma, issued less than a week after her appointment, similarly alarmed agency insiders by trumpeting the emergency authorization as “Another Achievement in Administration’s Fight Against [the] viagra.”.

In fact, frequent or increasing episodes read the full info here of listening fatigue is a symptom of early hearing loss can you take cialis and viagra at the same time. Why hearing loss can make you tired The brain plays an important role in our ability to hear, understand and speak. The sensory hair cells of the inner ear are responsible for translating the noise the outer ear gathers into electrical signals, which they send along the auditory nerve to the brain. When hearing loss is present, the brain must work harder to make sense of the information it receives from the can you take cialis and viagra at the same time inner ear, which can be mentally exhausting.

Here's why. Each hair cell is responsible for translating a specific pitch or frequency. When these cells die or are damaged, the auditory system loses can you take cialis and viagra at the same time the ability to translate that frequency, causing the brain to work harder to process incoming information. Parts of the brain that process sound When hearing is normal, these three areas of the brain work with the auditory system to interpret sound and produce speech.

The temporal lobe is located behind your ears and extends to both sides of your brain. This is where the primary auditory cortex, which receives sensory can you take cialis and viagra at the same time information from the inner ear, is located. Wernicke’s area is located in the temporal lobe on the left side of the brain and is responsible for speech comprehension, Broca’s area, located in the lower portion of the left frontal lobe, is responsible for speech production Hearing aids can help with ear fatigue Depending upon the severity of the loss, hearing aids or cochlear implants can improve listening and speech comprehension and effectively decrease listening fatigue. A 2011 study by researchers at Vanderbilt University tested 16 adults between the ages of 47-69 years of age with mild to severe sensorineural hearing loss to see what effect hearing aids would have on listening effort and mental fatigue.

The participants’ word recognition, word recall and visual reaction time can you take cialis and viagra at the same time were tested with and without hearing aids. Results indicated that participants realized better word recall, and their reaction times were significantly faster with hearing aids than without. Coping with listening fatigue Even for those who have normal hearing, intense listening can be an exhausting experience. Here are a few tips for coping with listening fatigue throughout the day, regardless of can you take cialis and viagra at the same time whether you have normal hearing or hearing loss.

Take a break from the noise. If you don’t wear hearing aids, consider taking a walk in nature or along a quiet street or finding somewhere to close your eyes and relax for a few minutes. Even if you're a busy professional, find a quiet place to eat your lunch to provide a boost midday.

If you do wear hearing aids, take them out for a few minutes each day. Practice deep breathing. When you find yourself feeling overwhelmed, stressed or frustrated, spend a few minutes can you take cialis and viagra at the same time doing some deep breathing exercises. The activity will help clear your mind while reducing stress and blood pressure.

Eliminate background noise whenever possible. People with hearing loss often have trouble distinguishing speech from background can you take cialis and viagra at the same time noise. The less background noise your ears and brain have to process, the less taxing it will be to tune into the conversation and the more energy you'll have. Take a nap.

According to the can you take cialis and viagra at the same time National Sleep Foundation, a 20-30 minute nap can improve your alertness and performance without leaving you groggy or interfering with your nighttime sleep. Besides the energy boost a nap can provide, you'll get the added bonus of quiet time.

Pfizer free viagra

Over the past 20 years, a large body of research has documented a relationship between higher nurse-to-patient staffing ratios and better patient outcomes, including shorter hospital stays, lower rates of failure to prevent mortality after an in-hospital complication, inpatient mortality for multiple types of patients, hospital-acquired pneumonia, unplanned extubation, respiratory failure and cardiac arrest.1–5 In addition, patients report higher satisfaction when they are cared pfizer free viagra for in hospitals with higher staffing levels.6 https://eingrext.at/shop-neu/hausgemachte-vegane-zucchinicremesuppe/ 7To date, most studies have not identified an ‘optimal’ nurse staffing ratio,8 which creates a challenge for determining appropriate staffing levels. If increasing nurse staffing always produces at least some improvement in the quality of care, how does one determine what staffing level is best?. This decision is ultimately an economic one, pfizer free viagra balancing the benefits of nurse staffing with the other options for which those resources could be used.

It is in this context that hospitals develop staffing plans, generally based on historical patterns of patient acuity.Practical challenges of nurse staffingHospital staffing plans provide the structure necessary for determining hiring and scheduling, but fall short for a number of reasons. First, there are multiple ways in which patient acuity can be measured, which can have measurable effects on the staffing levels resulting from acuity models.9 Second, patient volume and acuity can shift rapidly with changes in the volume of admissions, discharges and transfers between pfizer free viagra units. Third, staffing plans provide little guidance regarding the optimal mix of permanent staff, variable staff and externally contracted staff.The paper by Saville and colleagues10 in this issue of BMJ Quality &.

Safety addresses the latter two pfizer free viagra issues by applying a simulation model to identify the optimal target for baseline nurse staffing in order to minimise periods of understaffing. Included in this model is consideration of the extent to which hospitals should leverage temporary personnel (typically obtained through an external agency) to fill gaps. The model acknowledges the likelihood that a hospital cannot realistically prevent all shifts from having a shortfall of nurses at all times, as well pfizer free viagra as the reality that hospital managers lack information about the best balance between permanent and temporary staff.

In addition, the analysis includes a calculation of the costs of each staffing approach, drawing from the records of 81 inpatient wards in four hospital organisations.The application of sophisticated simulation models and other advanced analyticl approaches to analysis of nurse staffing has been limited to date, and this paper is an exemplar of the value of such research. Recent studies have used machine learning methods to forecast hospital discharge volume,11 a discrete event simulation model to determine nursing staff needs in a neonatal intensive care unit,12 and a prediction model using machine learning and hierarchical linear regression to link variation in nurse staffing with patient outcomes.13 This new study applied a unique Monte Carlo simulation model to estimate pfizer free viagra demand for nursing care and test different strategies to meet demand.The results of the analysis are not surprising in that hospitals are much less likely to experience understaffed patient shifts if they aim to have higher baseline staffing. The data demonstrate a notable leftward skew, indicating that hospitals are more likely to have large unanticipated increases in patient volume and acuity than to have unanticipated decreases.

This results in hospitals being more likely pfizer free viagra to have shifts that are understaffed than shifts that are overstaffed, which inevitably places pressure on hospitals to staff at a higher level and/or have access to a larger pool of temporary nurses. It also is not surprising that hospitals will need to spend more money per patient day if they aim to reduce the percent of shifts that are understaffed. What is surprising about the results is that hospitals do not necessarily achieve cost savings by relying on temporary personnel versus setting regular staffing at a higher level.Trade-offs between permanent and temporary staffThe temporary nursing workforce enables healthcare facilities to maintain flexible yet full care teams based on patient care needs.

Hospitals can use temporary nurses to address staffing gaps during leaves of absence, turnover or gaps between recruitment of permanent nurses, pfizer free viagra as well as during high-census periods. Temporary personnel are typically more expensive on an hourly basis than permanent staff. In addition, over-reliance on temporary staff can have pfizer free viagra detrimental effects on permanent nurses’ morale and motivation.

Orientations prior to shifts are often limited, which leads to a twofold concern as temporary nurses feel ill-prepared for shifts and permanent staff feel flustered when required to bring the temporary nurse up to speed while being expected to continue normal operations.14 Agency nurses may be assigned to patients and units that are incongruent with their experience and skills—either to unfamiliar units, which affects their ability to confidently deliver care, or to less complex patients where they feel as if their skills are not used adequately.14 15 These issues can create tension between temporary and permanent nursing staff, which can be compounded by the wage disparity. Permanent staff might feel demoralised and expendable when working alongside temporary staff who are not integrated into the social fabric of the staff.16Hospital managers pfizer free viagra also must be cognisant of the potential quality impact of relying heavily on temporary nursing staff. Research on the impact of contingent nursing employment on costs and quality have often found negative effects on quality, including mortality, and higher costs.17 18 However, other studies have found that the association between temporary nursing staff and low quality result from general shortages of nursing staff, which make a hospital more likely to employ temporary staff, and not directly from the contingent staff.19–21 Thus, temporary nurses play an important role in alleviating staffing shortages that would otherwise lead to lower quality of care.22Charting a path forward in hospital management and healthcare researchThe maturation of electronic health records and expansion of computerised healthcare management systems provide opportunities both for improved decision making about workforce deployment and for advanced workforce research.

In the area of workforce management, nursing and pfizer free viagra other leaders have a growing array of workforce planning tools available to them. Such tools are most effective when they display clear information about predicted patient needs and staff availability, but managers still must rely on their on-the-ground understanding of their staff and their context of patient care.23 Integration of human resources data with patient outcomes data has revealed that individual nurses and their characteristics have important discrete effects on the quality of care.24 25 Future development of workforce planning tools should translate this evidence to practice. In addition, new technology platforms are emerging to facilitate direct matching between temporary healthcare personnel and healthcare organisations pfizer free viagra.

One recent study tested a smartphone-based application that allowed for direct matching of locum tenens physicians with a hospital in the English National Health Service, finding that the platform generated benefits including greater transparency and lower cost.26 Similar technologies for registered nurses could facilitate better matching between hospital needs and temporary nurses’ preparedness to meet those needs.Analytical methods that fully leverage the large datasets compiled through electronic health records, human resources systems and other sources can be applied to advance research on the composition of nursing teams to improve quality of care. As noted above, prior research has applied machine learning pfizer free viagra and discrete event simulation to analyses of healthcare staffing. Other recent studies have leveraged natural language processing of nursing notes to identify fall risk factors27 and applied data mining of human resources records to understand the job titles held by nurses.28 Linking these rapidly advancing analytical approaches that assess the outcomes and costs of nurse staffing strategies, such as the work by Saville and colleagues published in this issue, to data on the impact of nurse staffing on the long-term costs of patient care will further advance the capacity of hospital leaders to design cost-effective policies for workforce deployment.Guidelines aim to align clinical care with best practice.

However, simply publishing a guideline rarely triggers behavioural changes to match guideline recommendations.1–3 We thus transform guideline recommendations into actionable tasks by introducing interventions that promote behavioural changes meant to produce guideline-concordant care. Unfortunately, not much has changed in the 25 years since Oxman and colleagues concluded pfizer free viagra that we have no ‘magic bullets’ when it comes to changing clinician behaviour.4 In fact, far from magic bullets, interventions aimed at increasing the degree to which patients receive care recommended in guidelines (eg, educational interventions, reminders, audit and feedback, financial incentives, computerised decision support) typically produce disappointingly small improvements in care.5–10Much improvement work aims to ‘make the right thing to do the easy thing to do.’ Yet, design solutions which hardwire the desired actions remain few and far between. Further, improvement interventions which ‘softwire’ such actions—not guaranteeing that they occur, but at least increasing the likelihood that clinicians will deliver the care recommended in guidelines—mostly produce small improvements.5–9 Until this situation changes, we need to acknowledge the persistent reality that guidelines themselves represent a main strategy for promoting care consistent with current evidence, which means their design should promote the desired actions.11 12In this respect, guidelines constitute a type of clinical decision support.

And, like all decision support interventions, guidelines pfizer free viagra require. (1) user testing to assess if the content is understood as intended and (2) empirical testing to assess if the decision support provided by the guideline does in fact promote the desired behaviours. While the processes for developing guidelines have received substantial attention pfizer free viagra over the years,13–18 surprisingly little attention has been paid to empirically answering basic questions about the finished product.

Do users understand guidelines as intended?. And, what version of a given pfizer free viagra guideline engenders the desired behaviours by clinicians?. In this issue of BMJ Quality and Safety, Jones et al19 address this gap by using simulation to compare the frequency of medication errors when clinicians administer an intravenous medication using an existing guideline in the UK’s National Health Service (NHS) versus a revised and user-tested version of the guideline that more clearly promotes the desired actions.

Their findings demonstrate that changes to guideline design (through addition of actionable decision supports) based on user pfizer free viagra feedback does in fact trigger changes in behaviour that can improve safety. This is an exciting use of simulation, which we believe should encourage further studies in this vein.Ensuring end users understand and use guidelines as intendedJones and colleagues’ approach affords an opportunity to reflect on the benefits of user testing and simulation of guidelines. The design and evaluation of their revised guidelines provides an excellent example of a careful stepwise progression pfizer free viagra in the development and evaluation of a guideline as a type of decision support for clinicians.

First, in a prior study,20 they user tested the original NHS guidelines to improve retrieval and comprehension of information. The authors produced a revised guideline, which included reformatted sections as well as increased support for key calculations, such as for infusion rates. The authors again user tested the pfizer free viagra revised guideline, successfully showing higher rates of comprehension.

Note that user testing refers to a specific approach focused on comprehension rather than behaviour21 and is distinct from usability testing. Second, in the current study, Jones et al evaluated whether nurse and midwife end users exhibited the desired behavioural changes when given the revised guidelines (with addition of actionable decision supports), compared with a control group pfizer free viagra working with the current version of the guidelines used in practice. As a result, Jones and colleagues verify that end users (1) understand the content in the guideline and (2) actually change their behaviour in response to using it.Simulation can play a particularly useful role in this context, as it can help identify problems with users’ comprehension of the guideline and also empirically assess what behavioural changes occur in response to design changes in the guidelines.

The level of methodological pfizer free viagra control and qualitative detail that simulation provides is difficult to feasibly replicate with real-world pilot studies, and therefore simulation fills a critical gap.Jones et al report successful changes in behaviour due to the revised guidelines in which they added actionable decision supports. For example, their earlier user testing found that participants using the initial guidelines did not account for displacement volume when reconstituting the powdered drug, leading to dosing errors. A second error with the initial guidelines involved participants using the shortest infusion rate provided (eg, guidelines state ‘1 to 3 hours’), without realising that the shortest rate is not appropriate for certain doses (eg, 1 hour is appropriate pfizer free viagra for smaller doses, but larger doses should not be infused over 1 hour because the drug would then be administered faster than the maximum allowable infusion rate of 3 mg/kg/hour).

These two issues were addressed in the revised guidelines by providing key determinants for ‘action’ such as calculation formulas that account for displacement volume and infusion duration, thereby more carefully guiding end users to avoid these dose and rate errors. These changes to the guideline triggered specific behaviours pfizer free viagra (eg, calculations that account for all variables) that did not occur with the initial guidelines. Therefore, the simulation testing demonstrated the value of providing determinants for action, such as specific calculation formulas to support end users, by showing a clear reduction in dose and rate errors when using the revised guidelines compared with the initial guidelines.The authors also report that other types of medication-specific errors remained unaffected by the revised guidelines (eg, incorrect technique and flush errors)—the changes made did not facilitate the desired actions.

The initial guidelines indicate pfizer free viagra ‘DO NOT SHAKE’ in capital letters, and there is a section specific to ‘Flushing’. In contrast, the revised guidelines do not capitalise the warning about shaking the vial, but embed the warning with a numbered sequence in the medication preparation section, aiming to increase the likelihood of reading it at the appropriate time. The revised guidelines do not have a section specific to flushing, but embed the flushing instructions as an unnumbered step in the administration section.

Thus, the pfizer free viagra value of embedding technique and flushing information within the context of use was not validated in the simulation testing (ie, no significant differences in the rates of these errors), highlighting precisely the pivotal role that simulation can play in assessing whether attempts to improve usability result in actual behavioural changes.Finally, simulation can identify potential unintended consequences of a guideline. For instance, Jones and colleagues observed an increase in errors (although not statistically significant) that were not medication specific (eg, non-aseptic technique such as hand washing, swabbing vials with an alcohol wipe). Given that the revised guidelines were specific to the medication tested, it is unusual that we see a tendency toward a worsening effect on generic medication preparation pfizer free viagra skills.

Again, this finding was not significant, but we highlight this to remind ourselves of the very real possibility that some interventions might introduce new and unexpected errors in response to changing workflow and practice6. Simulations offer an opportunity to spot these risks in advance.Now that Jones pfizer free viagra et al have seen how the revised guidelines change behaviour, they are optimally positioned to move forward. On one hand, they have the option of revising the guidelines further in attempts to address these resistant errors, and on the other, they can consider designing other interventions to be implemented in parallel with their user-tested guidance.

At first glance, the errors that were pfizer free viagra resistant to change appear to be mechanical tasks that end users might think of as applying uniformly to multiple medications (eg, flush errors, non-aseptic technique). Therefore, a second intervention that has a more general scope (rather than drug specific) might be pursued. Regardless of what they decide to pursue, we applaud their measured approach and highlight that the key takeaway is that their next steps are supported with clearer evidence of what to expect when the guidelines are released—certainly a helpful piece of information to guide decisions as to whether broad implementation of guidelines is justified.Caveats and conclusionSimulation is not a panacea—it is not able to assess longitudinal adherence, and there are limitations to how realistically clinicians behave pfizer free viagra when observed for a few sample procedures when under the scrutiny of observers.

Further, studies where interventions are implemented to assess whether they move the needle on the outcomes we care about (eg, adverse events, length of stay, patient mortality) are needed and should continue. However, having end users physically perform clinical pfizer free viagra tasks with the intervention in representative environments represents an important strategy to assess the degree to which guidelines and other decision support interventions in fact promote the desired behaviours and to spot problems in advance of implementation. Such simulation testing is not currently a routine step in intervention design.

We hope it becomes a more common phenomenon, with more improvement work following the example of the approach so effectively demonstrated by Jones and colleagues..

Over the past 20 years, a large body of research has documented a relationship between higher nurse-to-patient staffing ratios and better patient outcomes, including shorter hospital stays, lower rates of failure to prevent mortality after an in-hospital complication, inpatient mortality for multiple types of patients, hospital-acquired pneumonia, unplanned extubation, respiratory failure and cardiac arrest.1–5 In addition, patients report higher satisfaction when they are cared for in hospitals with higher staffing levels.6 7To date, most studies have not identified an ‘optimal’ nurse staffing ratio,8 which creates a challenge can you buy viagra online for determining appropriate staffing levels.

In addition, the analysis includes a calculation of the costs of each staffing approach, drawing from the records of 81 inpatient wards in four hospital organisations.The application of sophisticated simulation models and other advanced analyticl approaches to analysis of nurse staffing has been limited to date, and this paper is an exemplar of the value of such research. Recent studies have used machine learning methods to forecast hospital discharge volume,11 a discrete event simulation model to determine nursing staff needs in a neonatal intensive care unit,12 and a prediction model using machine can you buy viagra online learning and hierarchical linear regression to link variation in nurse staffing with patient outcomes.13 This new study applied a unique Monte Carlo simulation model to estimate demand for nursing care and test different strategies to meet demand.The results of the analysis are not surprising in that hospitals are much less likely to experience understaffed patient shifts if they aim to have higher baseline staffing. The data demonstrate a notable leftward skew, indicating that hospitals are more likely to have large unanticipated increases in patient volume and acuity than to have unanticipated decreases.

This results in hospitals being more likely to have shifts that are understaffed than shifts that are overstaffed, which inevitably places pressure on hospitals to staff at a higher level and/or have access to a larger pool of can you buy viagra online temporary nurses. It also is not surprising that hospitals will need to spend more money per patient day if they aim to reduce the percent of shifts that are understaffed. What is surprising about the results is that hospitals do not necessarily achieve cost savings by relying on temporary personnel versus setting regular staffing at a higher level.Trade-offs between permanent and temporary staffThe temporary nursing workforce enables healthcare facilities to maintain flexible yet full care teams based on patient care needs. Hospitals can use temporary nurses to can you buy viagra online address staffing gaps during leaves of absence, turnover or gaps between recruitment of permanent nurses, as well as during high-census periods.

Temporary personnel are typically more expensive on an hourly basis than permanent staff. In addition, over-reliance on temporary can you buy viagra online staff can have detrimental effects on permanent nurses’ morale and motivation. Orientations prior to shifts are often limited, which leads to a twofold concern as temporary nurses feel ill-prepared for shifts and permanent staff feel flustered when required to bring the temporary nurse up to speed while being expected to continue normal operations.14 Agency nurses may be assigned to patients and units that are incongruent with their experience and skills—either to unfamiliar units, which affects their ability to confidently deliver care, or to less complex patients where they feel as if their skills are not used adequately.14 15 These issues can create tension between temporary and permanent nursing staff, which can be compounded by the wage disparity. Permanent staff might feel demoralised and expendable when working alongside temporary staff who are not integrated into the social fabric of the staff.16Hospital managers also must be cognisant of the potential quality can you buy viagra online impact of relying heavily on temporary nursing staff.

Research on the impact of contingent nursing employment on costs and quality have often found negative effects on quality, including mortality, and higher costs.17 18 However, other studies have found that the association between temporary nursing staff and low quality result from general shortages of nursing staff, which make a hospital more likely to employ temporary staff, and not directly from the contingent staff.19–21 Thus, temporary nurses play an important role in alleviating staffing shortages that would otherwise lead to lower quality of care.22Charting a path forward in hospital management and healthcare researchThe maturation of electronic health records and expansion of computerised healthcare management systems provide opportunities both for improved decision making about workforce deployment and for advanced workforce research. In the can you buy viagra online area of workforce management, nursing and other leaders have a growing array of workforce planning tools available to them. Such tools are most effective when they display clear information about predicted patient needs and staff availability, but managers still must rely on their on-the-ground understanding of their staff and their context of patient care.23 Integration of human resources data with patient outcomes data has revealed that individual nurses and their characteristics have important discrete effects on the quality of care.24 25 Future development of workforce planning tools should translate this evidence to practice. In addition, new technology platforms are emerging to facilitate direct matching between temporary healthcare personnel can you buy viagra online and healthcare organisations.

One recent study tested a smartphone-based application that allowed for direct matching of locum tenens physicians with a hospital in the English National Health Service, finding that the platform generated benefits including greater transparency and lower cost.26 Similar technologies for registered nurses could facilitate better matching between hospital needs and temporary nurses’ preparedness to meet those needs.Analytical methods that fully leverage the large datasets compiled through electronic health records, human resources systems and other sources can be applied to advance research on the composition of nursing teams to improve quality of care. As noted above, prior can you buy viagra online research has applied machine learning and discrete event simulation to analyses of healthcare staffing. Other recent studies have leveraged natural language processing of nursing notes to identify fall risk factors27 and applied data mining of human resources records to understand the job titles held by nurses.28 Linking these rapidly advancing analytical approaches that assess the outcomes and costs of nurse staffing strategies, such as the work by Saville and colleagues published in this issue, to data on the impact of nurse staffing on the long-term costs of patient care will further advance the capacity of hospital leaders to design cost-effective policies for workforce deployment.Guidelines aim to align clinical care with best practice. However, simply publishing a guideline rarely triggers behavioural changes to match guideline recommendations.1–3 We thus transform guideline recommendations into actionable tasks by introducing interventions that promote behavioural changes meant to produce guideline-concordant care.

Unfortunately, not much has changed in the 25 years since Oxman and colleagues concluded can you buy viagra online that we have no ‘magic bullets’ when it comes to changing clinician behaviour.4 In fact, far from magic bullets, interventions aimed at increasing the degree to which patients receive care recommended in guidelines (eg, educational interventions, reminders, audit and feedback, financial incentives, computerised decision support) typically produce disappointingly small improvements in care.5–10Much improvement work aims to ‘make the right thing to do the easy thing to do.’ Yet, design solutions which hardwire the desired actions remain few and far between. Further, improvement interventions which ‘softwire’ such actions—not guaranteeing that they occur, but at least increasing the likelihood that clinicians will deliver the care recommended in guidelines—mostly produce small improvements.5–9 Until this situation changes, we need to acknowledge the persistent reality that guidelines themselves represent a main strategy for promoting care consistent with current evidence, which means their design should promote the desired actions.11 12In this respect, guidelines constitute a type of clinical decision support. And, like all decision support interventions, can you buy viagra online guidelines require. (1) user testing to assess if the content is understood as intended and (2) empirical testing to assess if the decision support provided by the guideline does in fact promote the desired behaviours.

While the processes for developing guidelines have received substantial attention over the years,13–18 surprisingly little attention has been paid to empirically answering basic questions about the finished can you buy viagra online product. Do users understand guidelines as intended?. And, what version of a given can you buy viagra online guideline engenders the desired behaviours by clinicians?. In this issue of BMJ Quality and Safety, Jones et al19 address this gap by using simulation to compare the frequency of medication errors when clinicians administer an intravenous medication using an existing guideline in the UK’s National Health Service (NHS) versus a revised and user-tested version of the guideline that more clearly promotes the desired actions.

Their findings demonstrate that changes to guideline design (through addition of can you buy viagra online actionable decision supports) based on user feedback does in fact trigger changes in behaviour that can improve safety. This is an exciting use of simulation, which we believe should encourage further studies in this vein.Ensuring end users understand and use guidelines as intendedJones and colleagues’ approach affords an opportunity to reflect on the benefits of user testing and simulation of guidelines. The design and evaluation of their revised guidelines provides an excellent example of a careful stepwise progression in the development and evaluation of a guideline as a type can you buy viagra online of decision support for clinicians. First, in a prior study,20 they user tested the original NHS guidelines to improve retrieval and comprehension of information.

The authors produced a revised guideline, which included reformatted sections as well as increased support for key calculations, such as for infusion rates. The authors again user tested the revised guideline, successfully showing higher rates of can you buy viagra online comprehension. Note that user testing refers to a specific approach focused on comprehension rather than behaviour21 and is distinct from usability testing. Second, in the current study, Jones et al evaluated whether nurse and midwife end users exhibited the desired behavioural changes when given the revised guidelines (with addition of actionable decision supports), compared with a control group working can you buy viagra online with the current version of the guidelines used in practice.

As a result, Jones and colleagues verify that end users (1) understand the content in the guideline and (2) actually change their behaviour in response to using it.Simulation can play a particularly useful role in this context, as it can help identify problems with users’ comprehension of the guideline and also empirically assess what behavioural changes occur in response to design changes in the guidelines. The level of methodological control can you buy viagra online and qualitative detail that simulation provides is difficult to feasibly replicate with real-world pilot studies, and therefore simulation fills a critical gap.Jones et al report successful changes in behaviour due to the revised guidelines in which they added actionable decision supports. For example, their earlier user testing found that participants using the initial guidelines did not account for displacement volume when reconstituting the powdered drug, leading to dosing errors. A second error with the initial guidelines involved participants using the shortest infusion rate provided (eg, guidelines state ‘1 to 3 hours’), without realising that the shortest rate is not appropriate for certain doses (eg, 1 hour is appropriate for smaller doses, but larger can you buy viagra online doses should not be infused over 1 hour because the drug would then be administered faster than the maximum allowable infusion rate of 3 mg/kg/hour).

These two issues were addressed in the revised guidelines by providing key determinants for ‘action’ such as calculation formulas that account for displacement volume and infusion duration, thereby more carefully guiding end users to avoid these dose and rate errors. These changes to the guideline triggered specific behaviours (eg, calculations that account can you buy viagra online for all variables) that did not occur with the initial guidelines. Therefore, the simulation testing demonstrated the value of providing determinants for action, such as specific calculation formulas to support end users, by showing a clear reduction in dose and rate errors when using the revised guidelines compared with the initial guidelines.The authors also report that other types of medication-specific errors remained unaffected by the revised guidelines (eg, incorrect technique and flush errors)—the changes made did not facilitate the desired actions. The initial guidelines indicate ‘DO NOT SHAKE’ in capital letters, and there is a section specific can you buy viagra online to ‘Flushing’.

In contrast, the revised guidelines do not capitalise the warning about shaking the vial, but embed the warning with a numbered sequence in the medication preparation section, aiming to increase the likelihood of reading it at the appropriate time. The revised guidelines do not have a section specific to flushing, but embed the flushing instructions as an unnumbered step in the administration section. Thus, the value of embedding technique and flushing information within the context of use was can you buy viagra online not validated in the simulation testing (ie, no significant differences in the rates of these errors), highlighting precisely the pivotal role that simulation can play in assessing whether attempts to improve usability result in actual behavioural changes.Finally, simulation can identify potential unintended consequences of a guideline. For instance, Jones and colleagues observed an increase in errors (although not statistically significant) that were not medication specific (eg, non-aseptic technique such as hand washing, swabbing vials with an alcohol wipe).

Given that the revised guidelines were specific to the medication tested, it is unusual that we see a tendency toward a worsening effect on can you buy viagra online generic medication preparation skills. Again, this finding was not significant, but we highlight this to remind ourselves of the very real possibility that some interventions might introduce new and unexpected errors in response to changing workflow and practice6. Simulations offer an opportunity to can you buy viagra online spot these risks in advance.Now that Jones et al have seen how the revised guidelines change behaviour, they are optimally positioned to move forward. On one hand, they have the option of revising the guidelines further in attempts to address these resistant errors, and on the other, they can consider designing other interventions to be implemented in parallel with their user-tested guidance.

At first glance, the errors that were resistant to change can you buy viagra online appear to be mechanical tasks that end users might think of as applying uniformly to multiple medications (eg, flush errors, non-aseptic technique). Therefore, a second intervention that has a more general scope (rather than drug specific) might be pursued. Regardless of what they decide to pursue, we applaud their measured approach and highlight that the key takeaway is that their next steps are supported with clearer evidence of what to expect when the guidelines are released—certainly a helpful piece of information to guide decisions as to whether broad implementation of guidelines is justified.Caveats and conclusionSimulation is not a panacea—it is not able to assess longitudinal adherence, and can you buy viagra online there are limitations to how realistically clinicians behave when observed for a few sample procedures when under the scrutiny of observers. Further, studies where interventions are implemented to assess whether they move the needle on the outcomes we care about (eg, adverse events, length of stay, patient mortality) are needed and should continue.

However, having end users physically perform clinical tasks with the intervention in representative environments represents can you buy viagra online an important strategy to assess the degree to which guidelines and other decision support interventions in fact promote the desired behaviours and to spot problems in advance of implementation. Such simulation testing is not currently a routine step in intervention design. We hope it becomes a more common phenomenon, with more improvement work following the example of the approach so effectively demonstrated by Jones and colleagues..
