Although more drug makers are settling patent infringement online pharmacy viagra lawsuits, what would happen if a girl took viagra the U.S. Federal Trade Commission found that the number of so-called pay-to-delay settlements — which the agency argues unfairly robs Americans of lower-cost alternatives to their prescription medicines — remain very low.In discussing the findings, which were from fiscal year 2017, agency officials maintained the decline underscores the effects of a 2012 U.S. Supreme Court ruling that such deals can be subject to review for anti-competitive agreements. Since then, the FTC has become more aggressive in challenging some patent settlements between brand-name and generic online pharmacy viagra drug makers.

Imaging the encephalopathy of prematurityJulia resource Kline and colleagues assessed MRI findings at term in 110 preterm infants born before 32 weeks’ gestation and cared lady viagra tablet for in four neonatal units in Columbus, Ohio. Using automated cortical and sub-cortical segmentation they analysed cortical surface area, sulcal depth, gyrification index, inner cortical curvature and thickness. These measures lady viagra tablet of brain development and maturation were related to the outcomes of cognitive and language testing undertaken at 2 years corrected age using the Bayley-III.

Increased surface area in nearly every brain region was positively correlated with Bayley-III cognitive and language scores. Increased inner cortical curvature was negatively correlated with both outcomes. Gyrification index and lady viagra tablet sulcal depth did not follow consistent trends.

These metrics retained their significance after sex, gestational age, socio-economic status and global injury score on structural MRI were included in the analysis. Surface area and inner cortical curvature explained approximately one-third of the variance in Bayley-III scores.In an accompanying editorial, David Edwards characterises the complexity of imaging and interpreting the combined effects of injury and dysmaturation on the developing brain. Major structural lesions are present in a minority of infants and the problems observed in later childhood require a much broader understanding of the effects lady viagra tablet of prematurity on brain development.

Presently these more sophisticated image-analysis techniques provide insights at a population level but the variation between individuals is such that they are not sufficiently predictive at an individual patient level to be of practical use to parents or clinicians in prognostication. Studies like this highlight the importance of follow-up programmes and help clinicians to avoid falling into the trap of equating normal (no major structural lesion) imaging studies with normal long term outcomes. See pages F460 and F458Drift at 10 yearsKaren Luuyt and colleagues report the cognitive outcomes at 10 lady viagra tablet years of the DRIFT (drainage, irrigation and fibrinolytic therapy) randomised controlled trial of treatment for post haemorrhagic ventricular dilatation.

They are to be congratulated for continuing to track these children and confirming the persistence of the cognitive advantage of the treatment that was apparent from earlier follow-up. Infants who received DRIFT were almost twice as likely to survive without severe cognitive disability lady viagra tablet than those who received standard treatment. While the confidence intervals were wide, the point estimate suggests that the number needed to treat for DRIFT to prevent one death or one case of severe cognitive disability was 3.

The original trial took place between 2003 and 2006 and was stopped early because of concerns about secondary intraventricular haemorrhage and it was only on follow-up that the advantages of the treatment became apparent. The study shows that secondary brain injury can be reduced by washing lady viagra tablet away the harmful debris of IVH. No other treatment for post-haemorrhagic ventricular dilatation has been shown to be beneficial in a randomised controlled trial.

Less invasive approaches to CSF drainage at different thresholds of ventricular enlargement later in the clinical course have not been associated with similar advantage. However the DRIFT treatment is complex and invasive and could only be provided in a small number of specialist referral centres and logistical challenges will need to be overcome to evaluate the treatment lady viagra tablet approach further. See page F466Chest compressionsWith a stable infant in the neonatal unit, it is common to review the events of the initial stabilisation and to speculate on whether chest compressions were truly needed to establish an effective circulation, or whether their use reflected clinician uncertainty in the face of other challenges.

Anne Marthe Boldinge and colleagues provide some objective data on the subject. They analysed videos that were recorded during neonatal stabilisation lady viagra tablet in a single centre with 5000 births per annum. From a birth population of almost 1200 infants there were good quality video recordings from 327 episodes of initial stabilisation where positive pressure ventilation was provided and 29 of these episodes included the provision of chest compressions, mostly in term infants.

6/29 of the infants who received chest compressions were retrospectively judged to have needed them. 8/29 had adequate spontaneous lady viagra tablet respiration. 18/29 received ineffective positive pressure ventilation prior to chest compressions.

5/29 had a heart rate greater than 60 lady viagra tablet beats per minute at the time of chest compressions. A consistent pattern of ventilation corrective actions was not identified. One infant received chest compressions without prior heart rate assessment.

See page 545Propofol for neonatal lady viagra tablet endotracheal intubationMost clinicians provide sedation/analgesia for neonatal intubations but there is still a lot of uncertainty about the best approach. Ellen de Kort and colleagues set out to identify the dose of propofol that would provide adequate sedation for neonatal intubation without side-effects. They conducted a dose-finding trial which evaluated a range of doses in infants of different gestations.

They ended their study after 91 infants because they only lady viagra tablet achieved adequate sedation without side effects in 13% of patients. Hypotension (mean blood pressure below post-mentrual age in the hour after treatment) was observed in 59% of patients. See page 489Growth to early adulthood following extremely preterm birthThe EPICure cohort comprised all babies born at 25 completed weeks of gestation or less in all 276 maternity units in the UK and Ireland from March to December 1995.

Growth data into adulthood are sparse for lady viagra tablet such immature infants. Yanyan Ni and colleagues report the growth to 19 years of 129 of the cohort in comparison with contemporary term born controls. The extremely preterm infants were on lady viagra tablet average 4.0 cm shorter and 6.8 kg lighter with a 1.5 cm smaller head circumference relative to controls at 19 years.

Body mass index was significantly elevated to +0.32 SD. With practice changing to include the provision of life sustaining treatment to greater numbers of infants born at 22 and 23 weeks of gestation there is a strong case for further cohort studies to include this population of infants. See page F496Premature birth is a worldwide problem, and the most significant cause lady viagra tablet of loss of disability-adjusted life years in children.

Impairment and disability among survivors are common. Cerebral palsy is diagnosed in around 10% of infants born before 33 weeks of gestation, although the rates approximately double in the smallest and most vulnerable infants, and other motor disturbances are being detected in 25%–40%. Cognitive, socialisation and behavioural problems are apparent in lady viagra tablet around half of preterm infants, and there is increased incidence of neuropsychiatric disorders, which develop as the children grow older.

Adults born preterm are approximately seven times more likely to be diagnosed with bipolar disease.1 2The neuropathological basis for these long-term and debilitating disorders is often unclear. Brain imaging by ultrasound or MRI shows that only a relatively small proportion of infants have significant destructive brain lesions, and these major lesions are not detected commonly enough to account for the prevalence of long-term impairments. However, abnormalities of brain growth and maturation are common, and it is now apparent that, in addition to recognisable cerebral damage, adverse neurological, cognitive and psychiatric outcomes are consistently associated with abnormal cerebral maturation and development.Currently, most clinical decision-making remains focused around a number of well-described cerebral lesions usually detected in routine practice using cranial ultrasound lady viagra tablet.

Viagra not working anymore

Rick Lange, MD viagra not working anymore. FDA regulation and approval of medical devices over the last 44 years.Elizabeth. What happens in the scientific literature when a citation is retracted?. Rick. And if you have a slipped disc, do you need to have your spine fused?.

Elizabeth. That's what we're talking about this week on TT HealthWatch, your weekly look at the medical headlines from Texas Tech University Health Sciences Center in El Paso. I'm Elizabeth Tracey, a Baltimore-based medical journalist.Rick. And I'm Rick Lange, president of Texas Tech University Health Sciences Center in El Paso, where I'm also the dean of the Paul L. Foster School of Medicine.

Elizabeth. Okay, Rick. Why don't we start first with the New England Journal of Medicine, because this is a long-standing issue about how to manage folks who have lumbar spine issues.Rick. This is a condition called degenerative spondylolisthesis. Whoa!.

What that means is a slipped disc. Usually when people have slipped disc, they have a disc that's bulging, leg pain, back pain, restricted activity, and we usually treat that conservatively and most people respond. But some don't, and if they have symptoms that persist over a long period of time despite non-surgical therapy, then they are recommended for surgery oftentimes. The old surgery used to be what's called a decompression surgery or laminectomy. That's to take the pressure off the nerve root to relieve the pain.

But more recently, 90% of the procedures in the United States have also been associated with spinal fusion at the same time. That's the use of screws and rods, bone grafts, to actually fuse the vertebral bones to prevent additional slippage of the disc. Is that really necessary?. So this was an open-label, multicenter, non-inferiority trial that involved patients that had symptomatic bulging disc and they hadn't responded to conservative management. It was just a single disc that was slipped.

They had not had previous surgery. It wasn't a severe narrowing and they were randomized to either have just decompression or decompression with spinal fusion. Two years later, what are their symptoms, how disabled are they, and how often do they need to have a reoperation?. Does spinal fusion actually help?. What they had discovered in a group of over 267 patients -- and these are people by the way that had symptoms for, gosh, more than a year -- spinal fusion added no benefit to just doing decompression laminectomy with regard to symptoms or disability.

Now, there was a slightly lower risk of reoperation, about 9% in the fusion group versus 12.5% in the decompression-alone group.Elizabeth. Of course, this is a positive outcome as far as I'm concerned because it's significantly less intrusive with regard to the surgery itself. Also, what we know about those devices that are inserted in the spine is that they increase stiffness. If somebody is involved, for example, in an accident afterwards, this can be a bad place to have a fracture.Rick. Right.

Oftentimes what happens when you do the spinal fusion is it fuses those two vertebral bones and it reduces flexibility there, so it increases stress on the other ones. So oftentimes people need operations in the adjacent vertebral bones.Elizabeth. So many people have this particular problem. In fact, cadaveric studies have shown us that in fact the majority of us are going to have degeneration in that area of our spine as we age.Rick. Right.

About a decade ago, we spent over $13 billion, a higher cost of this than other surgical procedures such as knee and hip replacements, even percutaneous coronary intervention -- that is, putting stents in patients. Elizabeth. Let's turn now to JAMA. This is another issue that I think is really important and timely. This is the association of tapering opioid dosage in people who have been on long-term opioids and whether that's associated with mental health crises and other problems.

The looked from 2000 to 2019. They looked at this issue of shall we taper down somebody's opioids when they have been on them for a long time?. That they defined as at least a 15% relative reduction in their mean daily dose during any of six overlapping 60-day windows, within a 7-month follow-up period. They in their final cohort had 113,000 + people. Among those patients who underwent dose tapering, about half and half women and men.

Their mean age was 58. In fact, those post-tapering periods were associated with an adjusted incidence rate of 9.3 overdose events per 100 person years for those who were tapered, versus 5.5 in those non-tapered periods. They also had more mental health crises per 100 person years, the folks who were tapered than those who were not. The editorialist takes a look at this and says, "Wow, we need to rethink what we're doing here. Everybody thought this was a good idea."Rick.

Elizabeth, I was surprised at this. This is kind of a paradoxical increase in opioid-related harms associated with decreasing opioid use. I mean, you think, "OK, someone is on a high dose of opioids. The first thing we need to do is let's get them off of that to decrease their risk of overdose." And what happens, as you said, is if you withdraw them, especially too quickly, you do just the opposite. You make things worse.

I was really surprised at this.Here is the conundrum for physicians. We're told to taper patients. We know that a high dose is associated with an increased risk of overdose. We're afraid of tapering too slowly because we don't want to continue prescribing opioids to someone when we know that they shouldn't be on them. But what this study instructs me is that we need to develop a relationship with the patient, we need to find out what their needs are, we need to be willing to taper over a slow period of time, even if that requires prescribing opioids initially, and then work with the patient together so we can do it in a safe manner.Elizabeth.

Exactly. The other thing that the editorialist notes is that patients who are prescribed opioids for chronic pain and those with opiate use disorder report that they feel substantial stigma coming from clinicians. So establishing that therapeutic relationship and that trust is going to be really critically important to getting somebody tapered.Rick. You're right. This is a shared decision process.Elizabeth.

Indeed. So where are we now?. Rick. Another article in JAMA and this is really pertinent. We usually record early in the morning.

We're recording late at night because I was chairing an FDA panel. This particular study looks at FDA regulation and approval of medical devices from 1976 to 2020. For individuals that have always wondered, like, "How does the FDA work and how do they regulate stuff?. ," what you're going to discover is since the FDA really began regulating things in earnest in 1976, they have a number of different pathways available. It's meant to help speed things along.

They have done that, by the way, needing to assess fees on the manufacturers to provide them the resources to accomplish this. In 2017 and in 2018, there were more than 18,000 manufacturers producing an estimated 190,000 distinct medical [devices]. How does the FDA regulate that?. Well, they divide them into classes based upon how safe they are. Things like a band-aid or a thermometer, they're called Class I and there is really very little regulation.On the flip side, there are what are called Class III that could potentially be life-saving or life-harming devices.

If they are new, they go through a process called a pre-marketing approval. They usually indicate they have a study that proves that they're both safe and effective. When that's done, by the way, they can be approved. And the FDA, in general, about 1% of their products they evaluate goes through that pre-marketing approval. They usually do about 30 per year.Most of them come through what's called a 510(k).

That's a regulation that says, "Listen, if you're making a device and it's like another device and we've already approved it, it's equivalent, then you just show the data to the FDA, it doesn't have to go to a panel like I chaired today and we'll approve it." And 99% of devices are approved in this particular way.Elizabeth. Right. There are, however, noteworthy cases where things that have been put forward as very similar to things that have already been approved really aren't all that similar, and there are substantial changes and in some cases have resulted in harm. And so this is a situation that I think we need to scrutinize a little bit more carefully, just like accelerated approval for drugs.Rick. How does the FDA deal with that?.

Well, you can only deal with the information you have in front of you, and sometimes that's limited. A study may be done on a couple of hundred or a couple thousand patients and you may not be aware of complications associated with the device until it has been in hundreds of thousands of patients followed for not months but years. Let me give you a couple of examples. There was a particular hip device that was used in hip replacements that started to break down. We know that using a mesh for gynecologic surgery has complications.

Now we didn't realize that until it had been implanted in over 750,000 women. We followed them over the course of years. Now when that happens, the FDA can ask for a post-marketing study or look at the data and retract the device based upon the information that's available. That is the FDA trying to preserve our safety, but at the same time not slow down the process that gives us devices that we need. It's always a very fine balance.Elizabeth.

Spoken like someone who has just chaired a committee. I am a lot more harsh with regard to these procedures because I have spent so much time reporting on the harms of some of these things that come across the transom as approved.Rick. Right. Clearly, if you go to Europe, things are approved in Europe faster than they are here because there is less scrutiny associated with it. They are not perfect, but I can tell you I have worked with them now for over 12 years and they really struggle very much to try to get it right.

Elizabeth. Okay. We're going to agree to have slightly different viewpoints on this particular one. Now we're going to turn to JAMA Internal Medicine. Speaking of striving to get it right, wow, we have a problem with the medical and scientific literature.

This was a problem that I think most noteworthily many of us became aware of when a purported link between thimerosal and autism in routine immunizations was published in the literature and subsequently retracted. But, boy, look at how much damage that has done. And I would respectfully suggest that even some of our recalcitrant folks right now who don't want to get erectile dysfunction treatments are probably thinking about the specter of that study in the back of their heads.In this case, they took a look at two different studies, one was published online in The Lancet on May 22nd, 2020 and retracted on June 13th, 2020. They took a look at the Altmetric Attention Score and found out its score was 23,084. The second study claimed to investigate the association between cardiovascular disease, renin-angiotensin-aldosterone system inhibitor therapy, and erectile dysfunction treatment outcomes.

The first one was hydroxychloroquine. The second one was published in the New England Journal of Medicine, and, again, it was published on May 1st, 2020, retracted on June 4th, 2020, and still maintains this Attention Score of 3,727.Then they looked at the number of citations that were still in place for the two retracted studies. Again, a startling amount of citations in other papers that were referring to these studies. This clearly is a problem. What are we going to do when studies are retracted so that people don't keep on citing them?.

Rick. Large studies, what happened was the data couldn't be corroborated. As a result, these really good journals -- The Lancet and New England Journal of Medicine -- retracted the articles. And you're right. They were retracting articles and they are still citing them in the medical...

When I say citing them, someone else is writing an article about hydroxychloroquine, they review it and think, "Oh, it must work. I am going to cite this other article that proves it." Well, these were withdrawn.As you know, besides serving on the FDA, I serve as an associate editor for a couple of journals. That falls on the reviewers and the editors to catch that. That falls on the journal to screen those things out so it doesn't inadvertently come in the literature and keep giving these false notions or these false outcomes, or these false results.Elizabeth. It's great to put the onus on the editors.

I am just wondering if we can't somehow develop -- we've got lots of international databases -- some kind of international database that would just flag these things as retracted. When somebody attempts to put it into their reference page, it would say, "No, no, no."Rick. Elizabeth, that's a really good thought. You'd think you need a database because some of these are in obscure journals, but these were, again, The Lancet and New England Journal of Medicine. These were like high-visibility journals.

But I think your point is well taken. We ought to be able to automate it so that when someone cites that you say, "No, no, no, no, no, no. That is not a study you should cite because it was retracted."Elizabeth. Well, we'll see if that ever comes to pass. On that note, that's a look at this week's medical headlines from Texas Tech.

In it, Elizabeth Tracey, director of electronic media for Johns Hopkins Medicine, and Rick Lange, MD, president of the Texas Tech online pharmacy viagra University Health Sciences Center in El Paso, look at the top medical stories of the week.This week's topics include what happens when a study is retracted, is spinal fusion necessary, tapering opioids, and FDA approval of http://www.ec-libermann-illkirch-graffenstaden.ac-strasbourg.fr/?page_id=3383 medical devices.Program notes:0:40 Treatment of slipped discs1:40 Hadn't responded to conservative therapy2:40 Increase stiffness3:25 Tapering opioid dosage4:25 More overdose in those tapered5:25 Willing to taper slowly6:00 FDA approval of medical devices from 1976-20207:00 Class 3, lifesaving or life-harming potential8:00 Can only deal with information you have9:05 Approval in Europe faster9:22 Retraction of studies and subsequent citation10:25 Maintain attention scores11:25 Cited in new articles12:46 EndTranscript:Elizabeth Tracey.

What happens in the scientific literature when a citation is retracted?. Rick. And if you have a slipped disc, do you need to have your spine online pharmacy viagra fused?. Elizabeth.

That's what we're talking about this week on TT HealthWatch, your weekly look at the medical headlines from Texas Tech University Health Sciences Center in El Paso. I'm Elizabeth Tracey, online pharmacy viagra a Baltimore-based medical journalist.Rick.

Right. Oftentimes what happens when you do the spinal fusion is it fuses those two vertebral bones and it reduces flexibility there, so it increases stress on the other ones. So oftentimes people need operations in the adjacent vertebral bones.Elizabeth. So many people have this particular problem.

In fact, cadaveric studies have shown us that in fact the majority of us are going to have degeneration in that area of our spine as we age.Rick. Right. About a decade ago, we spent over $13 billion, a higher cost of this than other surgical procedures such as knee and hip replacements, even percutaneous coronary intervention -- that is, putting stents in patients. Elizabeth.

Let's turn now to JAMA. This is another issue that I think is really important and timely. This is the association of tapering opioid dosage in people who have been on long-term opioids and whether that's associated with mental health crises and other problems. The looked from 2000 to 2019.

They looked at this issue of shall we taper down somebody's opioids when they have been on them for a long time?. That they defined as at least a 15% relative reduction in their mean daily dose during any of six overlapping 60-day windows, within a 7-month follow-up period. They in their final cohort had 113,000 + people. Among those patients who underwent dose tapering, about half and half women and men.

Their mean age was 58. In fact, those post-tapering periods were associated with an adjusted incidence rate of 9.3 overdose events per 100 person years for those who were tapered, versus 5.5 in those non-tapered periods. They also had more mental health crises per 100 person years, the folks who were tapered than those who were not. The editorialist takes a look at this and says, "Wow, we need to rethink what we're doing here.

Everybody thought this was a good idea."Rick. Elizabeth, I was surprised at this. This is kind of a paradoxical increase in opioid-related harms associated with decreasing opioid use. I mean, you think, "OK, someone is on a high dose of opioids.

The first thing we need to do is let's get them off of that to decrease their risk of overdose." And what happens, as you said, is if you withdraw them, especially too quickly, you do just the opposite. You make things worse. I was really surprised at this.Here is the conundrum for physicians. We're told to taper patients.

We know that a high dose is associated with an increased risk of overdose. We're afraid of tapering too slowly because we don't want to continue prescribing opioids to someone when we know that they shouldn't be on them. But what this study instructs me is that we need to develop a relationship with the patient, we need to find out what their needs are, we need to be willing to taper over a slow period of time, even if that requires prescribing opioids initially, and then work with the patient together so we can do it in a safe manner.Elizabeth. Exactly.

The other thing that the editorialist notes is that patients who are prescribed opioids for chronic pain and those with opiate use disorder report that they feel substantial stigma coming from clinicians. So establishing that therapeutic relationship and that trust is going to be really critically important to getting somebody tapered.Rick. You're right. This is a shared decision process.Elizabeth.

Indeed. So where are we now?. Rick. Another article in JAMA and this is really pertinent.

We usually record early in the morning. We're recording late at night because I was chairing an FDA panel. This particular study looks at FDA regulation and approval of medical devices from 1976 to 2020. For individuals that have always wondered, like, "How does the FDA work and how do they regulate stuff?.

," what you're going to discover is since the FDA really began regulating things in earnest in 1976, they have a number of different pathways available. It's meant to help speed things along. They have done that, by the way, needing to assess fees on the manufacturers to provide them the resources to accomplish this. In 2017 and in 2018, there were more than 18,000 manufacturers producing an estimated 190,000 distinct medical [devices].

How does the FDA regulate that?. Well, they divide them into classes based upon how safe they are. Things like a band-aid or a thermometer, they're called Class I and there is really very little regulation.On the flip side, there are what are called Class III that could potentially be life-saving or life-harming devices. If they are new, they go through a process called a pre-marketing approval.

They usually indicate they have a study that proves that they're both safe and effective. When that's done, by the way, they can be approved. And the FDA, in general, about 1% of their products they evaluate goes through that pre-marketing approval. They usually do about 30 per year.Most of them come through what's called a 510(k).

That's a regulation that says, "Listen, if you're making a device and it's like another device and we've already approved it, it's equivalent, then you just show the data to the FDA, it doesn't have to go to a panel like I chaired today and we'll approve it." And 99% of devices are approved in this particular way.Elizabeth. Right. There are, however, noteworthy cases where things that have been put forward as very similar to things that have already been approved really aren't all that similar, and there are substantial changes and in some cases have resulted in harm. And so this is a situation that I think we need to scrutinize a little bit more carefully, just like accelerated approval for drugs.Rick.

How does the FDA deal with that?. Well, you can only deal with the information you have in front of you, and sometimes that's limited. A study may be done on a couple of hundred or a couple thousand patients and you may not be aware of complications associated with the device until it has been in hundreds of thousands of patients followed for not months but years. Let me give you a couple of examples.

There was a particular hip device that was used in hip replacements that started to break down. We know that using a mesh for gynecologic surgery has complications. Now we didn't realize that until it had been implanted in over 750,000 women. We followed them over the course of years.

Now when that happens, the FDA can ask for a post-marketing study or look at the data and retract the device based upon the information that's available. That is the FDA trying to preserve our safety, but at the same time not slow down the process that gives us devices that we need. It's always a very fine balance.Elizabeth. Spoken like someone who has just chaired a committee.

I am a lot more harsh with regard to these procedures because I have spent so much time reporting on the harms of some of these things that come across the transom as approved.Rick. Right. Clearly, if you go to Europe, things are approved in Europe faster than they are here because there is less scrutiny associated with it. They are not perfect, but I can tell you I have worked with them now for over 12 years and they really struggle very much to try to get it right.

Elizabeth. Okay. We're going to agree to have slightly different viewpoints on this particular one. Now we're going to turn to JAMA Internal Medicine.

Speaking of striving to get it right, wow, we have a problem with the medical and scientific literature. This was a problem that I think most noteworthily many of us became aware of when a purported link between thimerosal and autism in routine immunizations was published in the literature and subsequently retracted. But, boy, look at how much damage that has done. And I would respectfully suggest that even some of our recalcitrant folks right now who don't want to get erectile dysfunction treatments are probably thinking about the specter of that study in the back of their heads.In this case, they took a look at two different studies, one was published online in The Lancet on May 22nd, 2020 and retracted on June 13th, 2020.

They took a look at the Altmetric Attention Score and found out its score was 23,084. The second study claimed to investigate the association between cardiovascular disease, renin-angiotensin-aldosterone system inhibitor therapy, and erectile dysfunction treatment outcomes. The first one was hydroxychloroquine. The second one was published in the New England Journal of Medicine, and, again, it was published on May 1st, 2020, retracted on June 4th, 2020, and still maintains this Attention Score of 3,727.Then they looked at the number of citations that were still in place for the two retracted studies.

Again, a startling amount of citations in other papers that were referring to these studies. This clearly is a problem. What are we going to do when studies are retracted so that people don't keep on citing them?. Rick.

Large studies, what happened was the data couldn't be corroborated. As a result, these really good journals -- The Lancet and New England Journal of Medicine -- retracted the articles. And you're right. They were retracting articles and they are still citing them in the medical...

When I say citing them, someone else is writing an article about hydroxychloroquine, they review it and think, "Oh, it must work. I am going to cite this other article that proves it." Well, these were withdrawn.As you know, besides serving on the FDA, I serve as an associate editor for a couple of journals. That falls on the reviewers and the editors to catch that. That falls on the journal to screen those things out so it doesn't inadvertently come in the literature and keep giving these false notions or these false outcomes, or these false results.Elizabeth.

It's great to put the onus on the editors. I am just wondering if we can't somehow develop -- we've got lots of international databases -- some kind of international database that would just flag these things as retracted. When somebody attempts to put it into their reference page, it would say, "No, no, no."Rick. Elizabeth, that's a really good thought.

You'd think you need a database because some of these are in obscure journals, but these were, again, The Lancet and New England Journal of Medicine. These were like high-visibility journals. But I think your point is well taken. We ought to be able to automate it so that when someone cites that you say, "No, no, no, no, no, no.

That is not a study you should cite because it was retracted."Elizabeth. Well, we'll see if that ever comes to pass.

Therapeutic creep in provision of hypothermia for viagra samples walgreens hypoxic ischaemic encephalopathyThree articles relate to the changing practices of UK clinicians in the provision of therapeutic hypothermia for hypoxic ischaemic encephalopathy (HIE). Lori Hage and colleagues report the clinical characteristics of term born infants treated with therapeutic hypothermia for a diagnosis of HIE in the UK between 2010 and 2017. The data viagra samples walgreens came from the National Neonatal Research Database and include infants who were treated for 3 days or who died during this period. There were 5201 infants who met this definition. The number of infants treated increased year on year until 2015 and then levelled out.

Markers of condition at birth suggested inclusion over time of greater numbers of infants with viagra samples walgreens less severe disease. The number of infants treated with a diagnosis of mild encephalopathy increased four-fold from 31 infants per year to 133 infants per year over the study period. There was no viagra samples walgreens important change in the number of infants treated with severe encephalopathy over the same time period. Lara Shipley and colleagues report temporal changes in the incidence of hypoxic-ischaemic encephalopathy in the UK between the time periods 2011–13 and 2014–16. The incidence of mild and of moderate or severe HIE remained stable between epochs suggesting that there has not been diagnostic creep driving the therapeutic creep.

The proportion of infants with mild viagra samples walgreens HIE who were treated with therapeutic hypothermia significantly increased over time between 2011–2013 (24.9%) and 2014–2016 (35.8%). The number of late preterm infants diagnosed with HIE also remained stable over time but again the proportion treated with hypothermia increased from 34% to 47%. This therapeutic creep, where larger numbers of infants are cooled who do not fulfil the criteria used to select infants for enrolment in the randomised controlled trials has been observed in other health systems. On the one hand it represents invasive treatment that is not well viagra samples walgreens supported by the evidence base. Further trials are called for to determine whether hypothermia is beneficial in milder cases.

The authors also point out that there is some is some subjectivity in the assessment of encephalopathy meaning that some clinicians don't cool borderline infants where others viagra samples walgreens would classify them with more severe encephalopathy. Unrelated to these articles but on the same theme we received a viewpoint from Mohamed Ali Tagin and Alastair Gunn. They argue that the criteria used to select infants for the trials were deliberately biased towards selecting infants at highest risk (and by inference not likely to have selected all infants that stand to benefit). The individual components of the inclusion criteria viagra samples walgreens perform poorly and are subjective. They encourage clinicians in doubt about whether an infant should be cooled to choose cooling because there is still an appreciable risk of adverse outcome and the treatment can be delivered safely, so that the potential benefits outweigh the potential harms.

They argue that viagra samples walgreens the limitations of the evidence should be discussed with the families involved. Perhaps therapeutic creep will push the trials out of reach. When new treatments are shown to be effective it is understandable that clinicians are keen to use them and this makes research more difficult before we know everything we want to know. This again viagra samples walgreens is a situation that would become less likely if we continue to work towards inclusive research models normalising routine involvement in enhancing the knowledge base. See pages F529, F501 and F458Methods for surfactant administrationA network meta-analysis by Ioannis Bellos and colleagues of 16 RCTs and 20 observational studies including data from more than 13 000 infants, suggests that thin catheter administration of surfactant is associated with lower rates of mortality, PVL, BPD and mechanical ventilation.

See page F474The cost of neonatal abstinence syndromePhilippa Rees and colleagues estimated the direct NHS costs of neonatal unit in-patient care for Neonatal Abstinence Syndrome in England between 2012 and 2017 using the National Neonatal Research Database. There were viagra samples walgreens 6411 admissions with this diagnosis during the study period (1.6 per 1000 births) and the incidence increased over time. The direct annual cost of care was £10 440 444, with a median cost of £7715 per infant. The median time to discharge was 10.2 days and this was viagra samples walgreens higher in the 49% of infants receiving pharmacotherapy. The emerging literature suggests that changes in the model of care away from neonatal unit admission could improve patient outcomes and greatly reduce costs.

See page F494Measurement of the effect of chest compressionsResuscitation council guidance advises on the depth of chest compressions during cardiopulmonary resuscitation in the newborn. Although it makes sense that compression depth is important viagra samples walgreens this is based on indirect information and extrapolation. Marlies Bruckner and colleagues developed an automated device that could deliver controlled compression depth and investigated its effect on piglets with experimental asphyxia to asystole. Compression depth made viagra samples walgreens an important difference to carotid blood flow and systolic blood pressure. See page F553Face mask versus nasal prong or nasopharyngeal tube for neonatal resuscitation in the delivery roomAvneet Magnat and colleagues performed a systematic review of evidence relating to the best interface for providing respiratory support in the delivery room.

They identified five randomised controlled trials involving 873 infants. There was viagra samples walgreens no difference in mortality between devices. Confidence intervals for most outcomes were wide indicating the need for more data. Difference in rates of intubation in the delivery room and need for chest compressions during initial stabilisation suggest that more data may uncover clinically important differences. It will be interesting to see how this meta-analysis changes after inclusion of data from the recently completed CORSAD trial viagra samples walgreens.
