The Royal Pharmaceutical Society and the British Pharmaceutical Students’ Association have called for all overseas candidates to sit the March 2021 registration assessment in their home countries.

The government implied wholesalers had more personal protective equipment in stock than was the case during the first wave of the COVID-19 pandemic, the Healthcare Distribution Association has said.

Community pharmacies should be reimbursed for their additional costs during the COVID-19 pandemic “as soon as possible”, the prime minister has told The Pharmaceutical Journal.

The General Pharmaceutical Council has said it is “double, treble, quadruple-checking” for any “flexibility” that would allow all overseas candidates to sit the March 2021 registration assessment exam in their countries of residence.

PDUFA V commitments signal a strong commitment to tolerance of open debate in the face of uncertainty.

I can admit to a rather powerful lack of enthusiasm when reading about interpersonal squabbles. It’s even worse in the scientific world: when I read about debates getting mired in personal attacks I tend to simply stop reading and move on to something else.

However, the really interesting part of this week’s meeting of an FDA joint Advisory Committee to discuss the controversial diabetes drug Avandia – at least in the sense of likely long-term impact – is not the scientific question under discussion, but the surfacing and handling of the raging interpersonal battle going on right now inside the Division of Cardiovascular and Renal Products. So I'll have to swallow my distaste and follow along with the drama.

Two words that make us mistrust Duke:  Anil Potti Christian Laettner

Not that the scientific question at hand – does Avandia pose significant heart risks? – isn't interesting. It is. But if there’s one thing that everyone seems to agree on, it’s that we don’t have good data on the topic. Despite the re-adjudication of RECORD, no one trusts its design (and, ironically, the one trial with a design to rigorously answer the question was halted after intense pressure, despite an AdComm recommendation that it continue).  And no one seems particularly enthused about changing the current status of Avandia: in all likelihood it will continue to be permitted to be marketed under heavy restrictions. Rather than changing the future of diabetes, I suspect the committee will be content to let us slog along the same mucky trail.

The really interesting question, that will potentially impact CDER for years to come, is how it can function with frothing, open dissent among its staffers. As has been widely reported, FDA reviewer Tom Marciniak has written a rather wild and vitriolic assessment of the RECORD trial, excoriating most everyone involved. In a particularly stunning passage, Marciniak appears to claim that the entire output of anyone working at Duke University cannot be trusted because of the fraud committed by Duke cancer researcher Anil Potti:

I would have thought that the two words “Anil Potti” are sufficient for convincing anyone that Duke University is a poor choice for a contractor whose task it is to confirm the integrity of scientific research. 

(One wonders how far Marciniak is willing to take his guilt-by-association theme. Are the words “Cheng Yi Liang” sufficient to convince us that all FDA employees, including Marciniak, are poor choices for deciding matter relating to publicly-traded companies? Should I not comment on government activities because I’m a resident of Illinois (my two words: “Rod Blagojevich”)?)

Rather than censoring or reprimanding Marciniak, his supervisors have taken the extraordinary step of letting him publicly air his criticisms, and then they have in turn publicly criticized his methods and approach.

I have been unable to think of a similar situation at any regulatory agency. The tolerance for dissent being displayed by FDA is, I believe, completely unprecedented.

And that’s the cliffhanger for me: can the FDA’s commitment to transparency extend so far as to accommodate public disagreements about its own approval decisions? Can it do so even when the disagreements take an extremely nasty and inappropriate tone?

• Rather than considering that open debate is a good thing, will journalists jump on the drama and portray agency leadership as weak and indecisive?
• Will the usual suspects in Congress be able to exploit this disagreement for their own political gain? How many House subcommittees will be summoning Janet Woodcock in the coming weeks?

I think what Bob Temple and Norman Stockbridge are doing is a tremendous experiment in open government. If they can pull it off, it could force other agencies to radically rethink how they go about crafting and implementing regulations. However, I also worry that it is politically simply not a viable approach, and that the agency will ultimately be seriously hurt by attacks from the media and legislators.

Where is this coming from?

As part of its recent PDUFA V commitment, the FDA put out a fascinating draft document, Structured Approach to Benefit-Risk Assessment in Drug Regulatory Decision-Making. It didn't get a lot of attention when first published back in February (few FDA documents do). However, it lays out a rather bold vision for how the FDA can acknowledge the existence of uncertainty in its evaluation of new drugs. Its proposed structure even envisions an open and honest accounting of divergent interpretations of data:

When they're frothing at the mouth, even Atticus doesn't let them publish a review

A framework for benefit-risk decision-making that summarizes the relevant facts, uncertainties, and key areas of judgment, and clearly explains how these factors influence a regulatory decision, can greatly inform and clarify the regulatory discussion. Such a framework can provide transparency regarding the basis of conflicting recommendations made by different parties using the same information.

(Emphasis mine.)

Of course, the structured framework here is designed to reflect rational disagreement. Marciniak’s scattershot insults are in many ways a terrible first case for trying out a new level of transparency.

The draft framework notes that safety issues, like Avandia, are some of the major areas of uncertainty in the regulatory process. Contrast this vision of coolly and systematically addressing uncertainties with the sad reality of Marciniak’s attack:

In contrast to the prospective and highly planned studies of effectiveness, safety findings emerge from a wide range of sources, including spontaneous adverse event reports, epidemiology studies, meta-analyses of controlled trials, or in some cases from randomized, controlled trials. However, even controlled trials, where the evidence of an effect is generally most persuasive, can sometimes provide contradictory and inconsistent findings on safety as the analyses are in many cases not planned and often reflect multiple testing. A systematic approach that specifies the sources of evidence, the strength of each piece of evidence, and draws conclusions that explain how the uncertainty weighed on the decision, can lead to more explicit communication of regulatory decisions. We anticipate that this work will continue beyond FY 2013.

I hope that work will continue beyond 2013. Thoughtful, open discussions of real uncertainties are one of the most worthwhile goals FDA can aspire to, even if it means having to learn how to do so without letting the Marciniaks of the world scuttle the whole endeavor.

There has been considerable noise coming out of the UK lately about successes in clinical trial enrollment.

First, a couple months ago came the rather dramatic announcement that clinical trial participation in the UK had "tripled over the last 6 years". That announcement, by the chief executive of the

Sweet creature of bombast: is Sir John writing press releases for the NIHR?

National Institute of Health Research's Clinical Research Network, was quickly and uncritically picked up by the media.

That immediately caught my attention. In large, global trials, most pharmaceutical companies I've worked with can do a reasonable job of predicting accrual levels in a given country. I like to think that if participation rates in any given country had jumped that heavily, I’d have heard something.

(To give an example: looking at a quite-typical study I worked on a few years ago: UK sites were overall slightly below the global average. The highest-enrolling countries were about 2.5 times as fast. So, a 3-fold increase in accruals would have catapulted the UK from below average to the fastest-enrolling country in the world.)

Further inquiry, however, failed to turn up any evidence that the reported tripling actually corresponded to more human beings enrolled in clinical trials. Instead, there is some reason to believe that all we witnessed was increased reporting of trial participation numbers.

Now we have a new source of wonder, and a new giant multiplier coming out of the UK. As the Director of the NIHR's Mental Health Research Network, Til Wykes, put it in her blog coverage of her own paper:

Our research on the largest database of UK mental health studies shows that involving just one or two patients in the study team means studies are 4 times more likely to recruit successfully.

Again, amazing! And not just a tripling – a quadrupling!

Understand: I spend a lot of my time trying to convince study teams to take a more patient-focused approach to clinical trial design and execution. I desperately want to believe this study, and I would love having hard evidence to bring to my clients.

At first glance, the data set seems robust. From the King's College press release:

Published in the British Journal of Psychiatry, the researchers analysed 374 studies registered with the Mental Health Research Network (MHRN).

Studies which included collaboration with service users in designing or running the trial were 1.63 times more likely to recruit to target than studies which only consulted service users.  Studies which involved more partnerships - a higher level of Patient and Public Involvement (PPI) - were 4.12 times more likely to recruit to target.

But here the first crack appears. It's clear from the paper that the analysis of recruitment success was not based on 374 studies, but rather a much smaller subset of 124 studies. That's not mentioned in either of the above-linked articles.

And at this point, we have to stop, set aside our enthusiasm, and read the full paper. And at this point, critical doubts begin to spring up, pretty much everywhere.

First and foremost: I don’t know any nice way to say this, but the "4 times more likely" line is, quite clearly, a fiction. What is reported in the paper is a 4.12 odds ratio between "low involvement" studies and "high involvement" studies (more on those terms in just a bit).  Odds ratios are often used in reporting differences between groups, but they are unequivocally not the same as "times more likely than".

This is not a technical statistical quibble. The authors unfortunately don’t provide the actual success rates for different kinds of studies, but here is a quick example that, given other data they present, is probably reasonably close:

• A Studies: 16 successful out of 20 
• Probability of success: 80% 
• Odds of success: 4 to 1
• B Studies: 40 successful out of 80
• Probability of success: 50%
• Odds of success: 1 to 1

From the above, it’s reasonable to conclude that A studies are 60% more likely to be successful than B studies (the A studies are 1.6 times as likely to succeed). However, the odds ratio is 4.0, similar to the difference in the paper. It makes no sense to say that A studies are 4 times more likely to succeed than B studies.

This is elementary stuff. I’m confident that everyone involved in the conduct and analysis of the MHRN paper knows this already. So why would Dr Wykes write this? I don’t know; it's baffling. Maybe someone with more knowledge of the politics of British medicine can enlighten me.

If a pharmaceutical company had promoted a drug with this math, the warning letters and fines would be flying in the door fast. And rightly so. But if a government leader says it, it just gets recycled verbatim.

The other part of Dr Wykes's statement is almost equally confusing. She claims that the enrollment benefit occurs when "involving just one or two patients in the study team". However, involving one or two patients would seem to correspond to either the lowest ("patient consultation") or the middle level of reported patient involvement (“researcher initiated collaboration”). In fact, the "high involvement" categories that are supposed to be associated with enrollment success are studies that were either fully designed by patients, or were initiated by patients and researchers equally. So, if there is truly a causal relationship at work here, improving enrollment would not be merely a function of adding a patient or two to the conversation.

There are a number of other frustrating aspects of this study as well. It doesn't actually measure patient involvement in any specific research program, but uses just 3 broad categories (that the researchers specified at the beginning of each study). It uses an arbitrary and undocumented 17-point scale to measure "study complexity", which collapses and quite likely underweights many critical factors into a single number. The enrollment analysis excluded 11 studies because they weren't adequate for a factor that was later deemed non-significant. And probably the most frustrating facet of the paper is that the authors share absolutely no descriptive data about the studies involved in the enrollment analysis. It would be completely impossible to attempt to replicate its methods or verify its analysis. Do the authors believe that "Public Involvement" is only good when it’s not focused on their own work?

However, my feelings about the study and paper are an insignificant fraction of the frustration I feel about the public portrayal of the data by people who should clearly know better. After all, limited evidence is still evidence, and every study can add something to our knowledge. But the public misrepresentation of the evidence by leaders in the area can only do us harm: it has the potential to actively distort research priorities and funding.

Why This Matters

We all seem to agree that research is too slow. Low clinical trial enrollment wastes time, money, and the health of patients who need better treatment options.

However, what's also clear is that we lack reliable evidence on what activities enable us to accelerate the pace of enrollment without sacrificing quality. If we are serious about improving clinical trial accrual, we owe it to our patients to demand robust evidence for what works and what doesn’t. Relying on weak evidence that we've already solved the problem ("we've tripled enrollment!") or have a method to magically solve it ("PPI quadrupled enrollment!") will cause us to divert significant time, energy, and human health into areas that are politically favored but less than certain to produce benefit. And the overhyping those results by research leadership compounds that problem substantially. NIHR leadership should reconsider its approach to public discussion of its research, and practice what it preaches: critical assessment of the data.

Did that rock move, or is it a squirrel crossing the road? Tracking objects that look a lot like their surroundings is a big problem for many autonomous vision systems. AI algorithms can solve this camouflage problem, but they take time and computing power. A new camera designed by researchers in South Korea provides a faster solution. The camera takes inspiration from the eyes of a cat, using two modifications that let it distinguish objects from their background, even at night.

“In the future … a variety of intelligent robots will require the development of vision systems that are best suited for their specific visual tasks,” says Young Min Song, a professor of electrical engineering and computer science at Gwangju Institute of Science and Technology and one of the camera’s designers. Song’s recent research has been focused on using the “perfectly adapted” eyes of animals to enhance camera hardware, allowing for specialized cameras for different jobs. For example, fish eyes have wider fields of view as a consequence of their curved retinas. Cats may be common and easy to overlook, he says, but their eyes actually offer a lot of inspiration.

This particular camera copied two adaptations from cats’ eyes: their vertical pupils and a reflective structure behind their retinas. Combined, these allowed the camera to be 10 percent more accurate at distinguishing camouflaged objects from their backgrounds and 52 percent more efficient at absorbing incoming light.

Using a vertical pupil to narrow focus

While conventional cameras can clearly see the foreground and background of an image, the slitted pupils of a cat focus directly on a target, preventing it from blending in with its surroundings. Kim et al./Science Advances

In conventional camera systems, when there is adequate light, the aperture—the camera’s version of a pupil—is small and circular. This structure allows for a large depth of field (the distance between the closest and farthest objects in focus), clearly seeing both the foreground and the background. By contrast, cat eyes narrow to a vertical pupil during the day. This shifts the focus to a target, distinguishing it more clearly from the background.

The researchers 3D printed a vertical slit to use as an aperture for their camera. They tested the vertical slit using seven computer vision algorithms designed to track moving objects. The vertical slit increased contrast between a target object and its background, even if they were visually similar. It beat the conventional camera on five of the seven tests. For the two tests it performed worse than the conventional camera, the accuracies of the two cameras were within 10 percent of each other.

Using a reflector to gather additional light

Cats can see more clearly at night than conventional cameras due to reflectors in their eyes that bring extra light to their retinas.Kim et al./Science Advances

Cat eyes have an in-built reflector, called a tapetum lucidum, which sits behind the retina. It reflects light that passes through the retina back at it, so it can process both the incoming light and reflected light, giving felines superior night vision. You can see this biological adaptation yourself by looking at a cat’s eyes at night: they will glow.

The researchers created an artificial version of this biological structure by placing a silver reflector under each photodiode in the camera. Photodiodes without a reflector generated current when more than 1.39 watts per square meter of light fell on them, while photodiodes with a reflector activated with 0.007 W/m² of light. That means the photodiode could generate an image with about 1/200th the light.

Each photodiode was placed above a reflector and joined by metal electrodes to create a curved image sensor.Kim et al./Science Advances

To decrease visual aberrations (imperfections in the way the lens of the camera focuses light), Song and his team opted to create a curved image sensor, like the back of the human eye. In such a setup, a standard image sensor chip won’t work, because it’s rigid and flat. Instead it often relies on many individual photodiodes arranged on a curved substrate. A common problem with such curved sensors is that they require ultrathin silicon photodiodes, which inherently absorb less light than a standard imager’s pixels. But reflectors behind each photodiode in the artificial cat’s eye compensated for this, enabling the researchers to create a curved imager without sacrificing light absorption.

Together, vertical slits and reflectors led to a camera that could see more clearly in the dark and isn’t fooled by camouflage. “Applying these two characteristics to autonomous vehicles or intelligent robots could naturally improve their ability to see objects more clearly at night and to identify specific targets more accurately,” says Song. He foresees this camera being used for self-driving cars or drones in complex urban environments.

Song’s lab is continuing to work on using biological solutions to solve artificial vision problems. Currently, they are developing devices that mimic how brains process images, hoping to one day combine them with their biologically-inspired cameras. The goal, says Song, is to “mimic the neural systems of nature.”

Song and his colleague’s work was published this week in the journal Science Advances.

Johnson & Johnson must pay US$15 million (S$19.6 million) to a Connecticut man who alleges that he developed mesothelioma, a rare form of cancer, as a result of using the company's talc powder for decades, a jury found on Tuesday (Oct 15). Plaintiff Evan Plotkin sued the company in 2021 soon after his diagnosis, saying he was sickened by inhaling J&J's baby powder. The jury in Fairfield County, Connecticut Superior Court also found that the company should pay additional punitive damages, which will be determined later by the judge overseeing the case. "Evan Plotkin and his trial team are thrilled that a jury once again decided to hold Johnson & Johnson accountable for their marketing and sale of a baby powder product that they knew contained asbestos," Ben Braly, a lawyer for Plotkin, said in an email. Erik Haas, J&J's worldwide vice president of litigation, said in a statement that the company would appeal "erroneous" rulings by the trial judge that kept the jury from hearing critical facts about the case.

To mark Breast Cancer Awareness Month, we speak to inspiring Singaporeans about their journey in battling and overcoming cancer.  Warda Ismail gets anxious about things easily, especially when it comes to her health.  So much so that her doctor once told her that she is a "borderline hypochondriac", she shared with AsiaOne in an interview.  For the uninitiated, hypochondria is a condition where a person is excessively and unduly worried about having a serious illness.

NEW YORK – Moves by major US fast-food chains to temporarily scrub fresh onions off their menus on Oct 24, after the vegetable was named as the likely source of an E. coli outbreak at McDonald’s, laid bare the recurring nightmare for restaurants: Produce is a bigger problem for restaurants to keep free of contamination than beef. Onions are likely the culprit in the McDonald’s E. coli outbreak across the Midwest and some Western states that has sickened 49 people and killed one, the US Department of Agriculture said late on Oct 23. The company pulled the Quarter Pounder off its menu at one-fifth of its 14,000 US restaurants. In past years, beef patties dominated the dockets of food-borne-illness lawyers, before US federal health regulators cracked down on beef contamination after an E. coli outbreak linked to Jack in the Box burgers hospitalised more than 170 people across states and killed four. As a result, beef-related outbreaks became much rarer, experts say.

NEW YORK — McDonald's on Sunday (Oct 27) ruled out beef patties as a source of the E. coli outbreak linked to Quarter Pounder hamburgers, which has killed at least one person and sickened nearly 75 others. "We remain very confident that any contaminated product related to this outbreak has been removed from our supply chain and is out of all McDonald's restaurants," the fast-food chain's chief supply chain officer Cesar Pina said in a statement. The Colorado Department of Agriculture said that all subsamples from multiple lots of McDonald's brand fresh and frozen beef patties had tested negative for E. coli, adding that it had completed beef testing and does not anticipate receiving further samples. McDonald's said it would resume distribution of fresh supplies of the Quarter Pounder and that it is expected to be available in all restaurants in the coming week, according to the statement.

The US Centers for Disease Control and Prevention said on Wednesday that slivered onions served on McDonald's, opens new tab Quarter Pounder hamburgers and other menu items were the likely source of an E. coli outbreak that sickened 90 people. The outbreak linked to Quarter Pounder was first reported on Oct 22, and slivered onions were suspected to be the source of the infections.

The FDA on Wednesday said it had initiated inspections at a Taylor Farms processing center in Colorado, a state where 29 people have fallen ill due to the outbreak. An onion grower of interest in Washington state is also being investigated, the FDA added. The CDC said the number of infected people has risen by 15 people from 75 and 27 persons have been hospitalised due to the illness, which has already killed one person.

David Duchovny and Gillian Anderson didn't speak to each other for "weeks at a time" when they worked on The X Files. The 64-year-old actor and Gillian, 56, enjoyed huge success with the iconic sci-fi series — but the duo actually had a turbulent relationship for many years. David said on the Fail Better podcast: "There was a long time, working on the show, where we were just not even dealing with one another off-camera. And there was a lot of tension. Which didn't matter, apparently, for the work cause we're both f****** crazy, I guess. We could just go out there and do what we needed to do." Gillian was amazed that they achieved so much success while their off-screen relationship was so tense.

Michelle Yeoh had never heard of Wicked before she was asked to join the cast of the movie-musical. The Oscar-winning actress plays Madame Morrible in the new film version of the hit stage show, which is based around characters first seen on screen in 1939 movie The Wizard of Oz. She's confessed she knew nothing about the popular musical before she was approached by director Jon M. Chu about joining the cast. According to The Hollywood Reporter, she said: "At that point, I had no clue what he was talking about because I had not seen Wicked the musical before. I knew Wizard of Oz, who doesn't, but not Wicked because I hadn't been going to the theatres and was not doing what I love which is watching musicals for quite a while, I hate to say." The new movie stars Cynthia Erivo as Elphaba and Ariana Grande as Glinda during their time at Shiz University in the Land of Oz with Michelle's character Madame Morrible serving as the school's headmistress. Michelle went on to say: "So I read it [the script] and called Jon back and said, 'This is a musical and she sings'. And he said, 'Oh easy, you'll have fun, you're up for the challenge.'

Monday blues were non-existent at the Singapore Indoor Stadium yesterday (Nov 11) as fans of Blackpink's Lisa strolled into the venue in their Y2K-style outfits inspired by the Thai singer's Rockstar music video. Singapore was the first stop for the 27-year-old's first solo fan-meet tour and needless to say, the excitement could be felt, and heard. Once the lights turned off and Lisa appeared, the screams were deafening. The show started with a bang, fittingly with her self-titled hit song Lalisa. Usually at fan-meets of K-pop idols, the special effects are kept to a minimum unlike concerts.
