Microbiota and obesity: Is it all hype?
> We still don’t have compelling evidence that differences in the composition of the gut microbiota significantly impact body fatness in humans, and the best human evidence we have suggests that it may not be important.  New evidence also suggests that it may not be as important in rodents as we thought either.  That said, the case isn’t closed yet.  The human evidence we have is short-term, and given the staggering complexity of the microbiota and how it interacts with diet and lifestyle, there is still room for it to be important.  I look forward to further research on it, but in the meantime, let’s cut back on the hype.

Health Care Employment Growth and the Future of US Cost Containment | Health Care Reform | JAMA | JAMA Network
> It is not surprising that employment growth should be a bellwether for rising health care expenditures because salaries and wages account for an average 55% of operating expenses for hospitals, physician offices, and outpatient care,4 and nearly 70% of hospital expenses.5 The problem is that the United States cannot reduce growth of health care costs without a corresponding moderation in the growth of health care employment.6 In the health care industry, this association is particularly strong because most hospitals have not-for-profit status. Unlike for-profit industries that will reduce employment and return profits to shareholders, not-for-profit entities cannot return their profits; instead they expand services. For example, a recent study7 found that hospitals experiencing an unexpected 10% boost in Medicare reimbursement rates added new technology, boosted nursing staff by 16%, and increased their payroll by nearly one-third.

Troubling Trends in Health Disparities | NEJM
> A recent report on mortality by the National Center for Health Statistics (NCHS)1 confirmed that life expectancy decreased in the United States for a second year in a row, from 78.9 years in 2014 to 78.7 years in 2015 to 78.6 years in 2016. Although these decreases were small, they indicate a change in the otherwise monotonically increasing life expectancy in recent decades. These decreases were the result of increasing mortality among persons between 15 and 64 years of age, with a marked increase in “unintentional injuries” (a 9.7% increase) and suicide (a 1.5% increase)

Among 10 functional annotations, haploinsufficiency scores best explain the association of any deletions with PIQ with a mean (SE) decrease of 2.74 (0.68) points per unit of the probability of being loss-of-function intolerant (P = 8 × 10−5). Results are consistent across cohorts and unaffected by sensitivity analyses removing pathogenic CNVs.

The richest 1 percent now owns more of the country’s wealth than at any time in the past 50 years - The Washington Post
> The wealthiest 1 percent of American households own 40 percent of the country's wealth, according to a new paper by economist Edward N. Wolff. That share is higher than it has been at any point since at least 1962, according to Wolff's data, which comes from the federal Survey of Consumer Finances.

From 2013, the share of wealth owned by the 1 percent shot up by nearly three percentage points. Wealth owned by the bottom 90 percent, meanwhile, fell over the same period. Today, the top 1 percent of households own more wealth than the bottom 90 percent combined. That gap, between the ultrawealthy and everyone else, has only become wider in the past several decades.

Tolerance is not a moral precept – Extra Newsfeed
> Tolerance is not a moral absolute; it is a peace treaty. Tolerance is a social norm because it allows different people to live side-by-side without being at each other’s throats. It means that we accept that people may be different from us, in their customs, in their behavior, in their dress, in their sex lives, and that if this doesn’t directly affect our lives, it is none of our business. But the model of a peace treaty differs from the model of a moral precept in one simple way: the protection of a peace treaty only extends to those willing to abide by its terms. It is an agreement to live in peace, not an agreement to be peaceful no matter the conduct of others. A peace treaty is not a suicide pact.

Really bad news following a 97-2 vote by the Senate. > SESTA/FOSTA undermines Section 230, the most important law protecting free speech online. Section 230 protects online platforms from liability for some types of speech by their users. Without Section 230, the Internet would look very different. It’s likely that many of today’s online platforms would never have formed or received the investment they needed to grow and scale—the risk of litigation would have simply been too high. Similarly, in absence of Section 230 protections, noncommercial platforms like Wikipedia and the Internet Archive likely wouldn’t have been founded given the high level of legal risk involved with hosting third-party content.

Fatebenefratelli Hospital - Wikipedia
> During the Nazi raid of the Jewish ghetto in Rome on October 16, 1943, Jewish escapees sought refuge at the hospital. Borromeo accepted them and declared that these new "patients" had been diagnosed with a contagious, fatal disease called Il Morbo di K ("the Syndrome K"), which could be interpreted as standing for "Koch disease" or "Kreps disease".[4][5] The name was suggested by physician and anti-fascist activist Adriano Ossicini.[3] The letter K was designated for the Jewish refugees to distinguish them from real patients. K was derived from the German officer Albert Kesselring, who led the troops in Rome, and from Sicherheitspolizei and Sicherheitsdienst chief Herbert Kappler, who was appointed as city police chief.[3] "Syndrome K" was purported to be a neurological illness whose symptoms included convulsions, dementia, paralysis, and, ultimately, death from asphyxiation.[6] While the symptoms of the disease were deliberately kept ambiguous, the Nazis were noted to refrain from investigating the hospital or even to conduct searches for Jews on the premises out of fear of contracting the disease.[4] The Jewish patients were advised to appear ill and to cough loudly, affecting symptoms similar to tuberculosis.[4]

Besides Fr. Maurizio and Borromeo, other doctors on staff assisted the Jewish patients and helped to move them to safer hideouts outside the hospital. In May 1944, the hospital was raided and five Jews from Poland were detained. However, the ruse saved approximately 100 refugees.[4]

[OPEN QUESTION] Insect declines: Why aren’t we dead already? | Eukaryote Writes Blog
> My guess is that ecologists like to overstate the importance of charismatic animals to ecosystems, including flying insects. Maybe they feed some birds and stuff, but birds also aren’t that important to ecosystems. (Non-human vertebrates are generally tiny footnotes to Earth’s ecology, which is dominated by plants, bacteria, and fungi.)

The paper “A Comparative Analysis of Soil Fauna Populations and Their Role in Decomposition Processes” says: “The soil fauna appears generally to be responsible for less than about 5% of total decomposer respiration” (p. 288). I assume that fungi/bacteria/actinomycetes/etc. account for most of it. In many composting operations, invertebrate animals are minor contributors to decomposition, mainly helping to speed up the process by mechanical breakdown of large pieces of organic matter. So it seems you don’t really need insects for nutrient cycling.

WTF! No neurogenesis in humans??
Would be interesting to try to find newly born cells in the human brain using single cell RNAseq. > Thus, it is unlikely that there are false-positives in Sorrells work, but there could be false negatives since some DCX-only or PSA-NCAM-only cells might really be legitimate adult-born neurons, because they could downregulate expression of one marker before another. Previous studies have also used DCX as a marker of adult neurogenesis in the human hippocampus. For example, the images by Epp et al are some of the nicest I’ve seen. Are they a bit odd-looking? Sure, maybe. But no one has ever described the morphology of newborn human hippocampal neurons so I don’t know what is normal. Are their DCX neurons a bit more in the hilus than I would expect from rodent studies? Perhaps, but again, might it be that if there is a germinal zone in adult humans, it looks different than rodents? Some previous human studies (eg Boldrini 2009) have examined a band that extends more into the molecular layer and hilus. Which is correct? I don’t know.

Glucocorticoid Signaling in Myeloid Cells Worsens Acute CNS Injury and Inflammation | Journal of Neuroscience
> Glucocorticoid stress hormones (GCs) are well known for being anti-inflammatory, but some reports suggest that GCs can also augment aspects of inflammation during acute brain injury. Because the GC receptor (GR) is ubiquitously expressed throughout the brain, it is difficult to know which cell types might mediate these unusual “proinflammatory” GC actions. We examined this with cell type-specific deletion or overexpression of GR in mice experiencing seizure or ischemia. Counter to their classical anti-inflammatory actions, GR signaling in myeloid cells increased Iba-1 and CD68 staining as well as nuclear p65 levels in the injured tissue. GCs also reduced levels of occludin, claudin 5, and caveolin 1, proteins central to blood–brain-barrier integrity; these effects required GR in endothelial cells. Finally, GCs compromised neuron survival, an effect mediated by GR in myeloid and endothelial cells to a greater extent than by neuronal GR.

Medical careers - Career review
> What if I’m already a doctor?
We recommend – especially for doctors early in their career – slanting your efforts more towards the promising areas within medicine (biomedical research, health policy work and public health, possibly healthcare management). Another approach, especially for later-career doctors who are in the ‘wrong’ field, is trying to maximise income for earning to give.

Can clinical practice be high-impact?
There is little data which can help answer the question, “Which medical specialty has the highest impact?” The best heuristic would be to try and look at where the need for medical care most greatly exceeds its supply. Within the developed world, this would suggest looking for ‘cinderella’ fields are neglected due to things like being stigmatized or poorly paid (psychiatry and mental health is a leading candidate). However, there are reasons to think – particularly in health systems like the UK – there should not be too great a discrepancy between the value of different specialties, or of working in different locations.

Slowing Biological Time to Extend the Golden Hour for Lifesaving Treatment
> DARPA created the Biostasis program to develop new possibilities for extending the golden hour, not by improving logistics or battlefield care, but by going after time itself, at least how the body manages it. Biostasis will attempt to directly address the need for additional time in continuously operating biological systems faced with catastrophic, life-threatening events. The program will leverage molecular biology to develop new ways of controlling the speed at which living systems operate, and thus extend the window of time following a damaging event before a system collapses. Essentially, the concept aims to slow life to save life.

“At the molecular level, life is a set of continuous biochemical reactions, and a defining characteristic of these reactions is that they need a catalyst to occur at all,” said Tristan McClure-Begley, the Biostasis program manager. “Within a cell, these catalysts come in the form of proteins and large molecular machines that transform chemical and kinetic energy into biological processes. Our goal with Biostasis is to control those molecular machines and get them to all slow their roll at about the same rate so that we can slow down the entire system gracefully and avoid adverse consequences when the intervention is reversed or wears off.”

The campaign pledged medically confidential treatment free-of-charge. It was initially funded by the Volkswagen Foundation, and has been financially supported by the German government since 2008.[5] The project's slogan is "You are not guilty because of your sexual desire, but you are responsible for your sexual behavior.

History of medical regulation in the United Kingdom - Wikipedia
> The earliest reference to medical regulation in the UK dates from 1421, when physicians petitioned parliament to ask that nobody without appropriate qualifications be allowed to practise medicine. The doctors said that unqualified practitioners caused "great harm and slaughter of many men".[1]:274

Despite agreement in principle from parliament, little more appeared to happen until 1511, when a statute placed regulation of the medical profession in the hands of the bishops. John Raach wrote that "the Church was apparently considered the one institution whose influence was extensive and potent enough to be effective in suppressing quacks and licensing the members of the medical profession". Raach further suggested that as a learned profession, medicine "could not be relegated to regulation by the average county official". Clerics, often the most highly educated members of society, were better suited to the task. Medicine and religion were also closely entwined: healing had long been associated with the supernatural, while the events of birth and death involved both medics and clerics.[1]:277–278

The purpose of the 1511 statute was to eliminate unqualified practitioners, and to that end it provided for a financial reward for those who reported them.

In 1518, the College of Physicians was founded and took over licensing of doctors in London. The College was founded by physicians themselves, meaning that in London the licensing of medicine was in the hands of the profession, rather than the bishop. Various disputes arose between the College, universities, and bishops over their authority to license and recognise each other's qualifications.

As doctors often covered large areas, crossing diocesan boundaries, they often required licenses from several bishops. At some point – it is unclear precisely when – archbishops were empowered to issue licenses for multiple dioceses. In the early seventeenth century, nearly a quarter of doctors received their licenses from archbishops.[1]:287

Reduction in Firearm Injuries during NRA Annual Conventions | NEJM
Clever study.
> Among 75,567,650 beneficiary-period observations in the claims analysis, 14.3% occurred on NRA convention dates. The unadjusted rate of firearm injuries was lower during convention dates than during control dates (129 beneficiaries with a firearm injury among 10,883,304 persons [1.19 per 100,000] vs. 963 beneficiaries with a firearm injury among 64,683,254 persons [1.49 per 100,000]; P=0.004; relative difference, 20.1%; 95% confidence interval, 6.7 to 34.0). The findings were unaffected by adjustment for covariates (Figure 1).

Reductions in firearm injuries during convention dates were largest among men, in the South and West, in states in the highest third of gun-ownership rates, and among people who resided in the state hosting the convention. There was no difference in the proportion of crimes involving a firearm between convention and control dates.

If the placebo group fails to catch up to the benefit seen in the active group, this indicates a lasting effect of the treatment on the course of disease. The FDA emphasized that this benefit must be shown on clinical tests, not just on biomarkers.

pdf -- Death and the Self
Tibetan Buddhist monks are not less afraid of death -- in fact they are more so, in this study. > It is an old philosophical idea that if the future self is literally different from the current self, one should be less concerned with the death of the future self (Parfit, 1984). This paper examines the relation between attitudes about death and the self among Hindus, Westerners, and three Buddhist populations (Lay Tibetan, Lay Bhutanese, and monastic Tibetans). Compared with other groups, monastic Tibetans gave particularly strong denials of the continuity of self, across several measures. We predicted that the denial of self would be associated with a lower fear of death and greater generosity toward others. To our surprise, we found the opposite. Monastic Tibetan Buddhists showed significantly greater fear of death than any other group. The monastics were also less generous than any other group about the prospect of giving up a slightly longer life in order to extend the life of another.

> A general decline in drinking has been seen since 1960, and further modeling will be required to determine if that explains falling dementia trends in developed countries, Schwarzinger added (Sep 2017 news; Nov 2016 news). Meanwhile, health care providers should be alert to the association between excessive alcohol consumption and cognitive decline. They could employ earlier and more aggressive screening and interventions to reduce its burden in the population, he said.

Deciding to quit medical school | Student Doctor Network
> Before proceeding consider this: I graduated medical school in 1981, residency, private practice, and wrote. It took seven years to get an agent, and another two to have my first novel published. That was over 32 books ago, 10 screenplays, and 2 features as executive producer. Fortunately I maintained the discipline of writing two-three hours a day, editing, and going across country frequently. Work in the arts is scarce, and dedication to my surgical practice (retired), rewarding, taxing, and fulfilling. Quitting medicine would have been foolish. Govern yourself accordingly.

Procalcitonin to initiate or discontinue antibiotics in acute respiratory tract infections. - PubMed - NCBI
> the use of procalcitonin to guide initiation and duration of antibiotic treatment results in lower risks of mortality, lower antibiotic consumption, and lower risk for antibiotic-related side effects. Results were similar for different clinical settings and types of ARIs, thus supporting the use of procalcitonin in the context of antibiotic stewardship in people with ARIs

Lessons for human genetics from genetic screens in model organisms
> For many human traits or disorders, especially ones involving the human mind, that detailed understanding is lacking. Oftentimes the phenotype is simply a word on a form – like “schizophrenia”. Moreover, while in model organisms we can simply screen out the indirect and non-specific mutations and focus on the ones directly involved in the processes of interest, we don’t have that luxury in humans. The indirect and non-specific ones will contribute most of the variance in risk.

At one level, that’s okay – just identifying these genetic risk factors can be tremendously useful in a clinical setting. But it does make getting at the underlying biology much more challenging. Nature is under no obligation to make things simple for us. It is going to take a hell of a lot more work after the initial discovery of genetic variants to unravel the biology of complex traits and disorders.

Recent Genetic Studies Claiming a Slowing of Aging may be Largely Incorrect – Fight Aging!
> It is fair to ignore most studies showing extension of life span in laboratory species conducted much prior to the turn of the century. A majority failed to control for calorie restriction, and thus the (usually small) effects evaporate when more rigorously tested. The way this works is that an intervention makes mice nauseous or otherwise uncomfortable, they eat less as a consequence, and thus live longer solely due to lowered calorie intake.

Technological Unemployment: Much More Than You Wanted To Know | Slate Star Codex
Scott arguing that it's technologic *underemployment* (people training for things, and then the jobs ceasing to exist sooner than they expected) that we should worry about. > 1. Technological unemployment is not happening right now, at least not more so than previous eras. The official statistics are confusing, but they show no signs of increases in this phenomenon. (70% confidence)

2. On the other hand, there are signs of technological underemployment – robots taking middle-skill jobs and then pushing people into other jobs. Although some people will be “pushed” into higher-skill jobs, many will be pushed into lower-skill jobs. This seems to be what happened to the manufacturing industry recently. (70% confidence)

3. This sort of thing has been happening for centuries and in theory everyone should eventually adjust, but there are some signs that they aren’t. This may have as much to do with changes to the educational, political, and economic system as with the nature of robots per se. (60% confidence)

Human service work, gender and antidepressant use: a nationwide register-based 19-year follow-up of 752 683 women and men | Occupational & Environmental Medicine
> The hazard of antidepressant use was higher among men working in human service versus all other occupations with the same skill/occupational level (1.22, 95% CI 1.18 to 1.27), but this was not the case for women (0.99, 95% CI 0.98 to 1.01). The risks differed between professions: male health and social care professionals (including medical doctors, nurses, practical nurses and home care assistants), social workers, childcare workers, teachers and psychologists had a higher risk of antidepressant use than men in non-human service occupations, whereas customer clerks had a lower risk.

A New Year’s Wish on Opioids | Substance Use and Addiction | JAMA | The JAMA Network
> On opioids, it can sometimes seem that there are 3 bad ideas for every good one. Public officials have supported limiting the number of naloxone resuscitations and afterwards letting people die, requiring drug testing before enrolling in Medicaid, and launching stigmatizing public relations campaigns that can reduce the chance people will seek treatment. Can we leave such approaches behind in 2017? Worth holding on to are approaches by states like Rhode Island, where the governor asked a team of local experts to listen to the public, consult the evidence, and provide recommendations for priority strategies. As one Rhode Island expert told an assembled group, “Our goal here is not to make everybody in this room happy. Our goal is to cut down on overdose deaths.” Three years later, after developing a terrific dashboard, investing in access to effective treatment, developing programs to improve prescribing of opioids and benzodiazepines, and setting standards for hospital activities, the state is one of a few actually seeing a decline in overdoses.

Attrition Rates Between Residents in Obstetrics and Gynecology and Other Clinical Specialties, 2000–2009 | Journal of Graduate Medical Education
The annual resident attrition rate in this paper (between 2000-2009) is highest in psych (7.9%) compared to other specialties. As shown in the figure, the annual proportion of residents who left was 4.0% for all clinical specialties, compared with 4.2% in Ob-Gyn. Attrition rates in Ob-Gyn were most similar to those in general surgery (5.1%), family medicine (4.7%), and anesthesiology (3.6%). Psychiatry was the only specialty with a higher mean attrition rate (7.9%), while much lower rates than Ob-Gyn were found in neurology (2.9%), pediatrics (2.9%), internal medicine (2.7%), and emergency medicine (1.5%).

Closed-loop stimulation of temporal cortex rescues functional networks and improves memory | Nature Communications
> "In a proof-of-concept study, researchers used direct brain stimulation to improve memory performance in epilepsy patients. Electrodes implanted to block seizures were instead used to stimulate the lateral temporal cortex to help encode memory. When the devices were switched on, participants saw a 15% boost in memory performance without adverse effects or knowledge that the device was in use. The authors are hopeful that the technique can be adapted to a non-invasive approach."

How Old is a Transplanted Organ? – Fight Aging!
> Recently, we studied the above mentioned miRs using single-miR real time-RT qPCR on blood serum samples from 34 recipients stratified on the basis of donor liver chronological age. No difference was observed, thus suggesting that the phenomenon previously found was tightly related to the organ itself without miR-specific exocytosis and changes at circulating level, at least for the identified miRs.

The possibility that a centenarian liver can still function properly may suggest not only the intrinsic peculiarity of this organ (slowed down ageing; regeneration phenomena), but also the interaction with the younger recipients.

> But for those fortunate enough to approach a normal life expectancy, people who are able to make plans and discuss death with loved ones will have an easier time with it. I can tell you from many people I have seen, those who are able to engage their mortality more deeply, and use this fact to inform and instruct their goals and decisions throughout their life, are more likely to be prepared and even content when the doctor has to tell them that their time is drawing near.

My personal moonshot - Marginal REVOLUTION
> By the way, I love it when people describe writing a blog, or writing on the internet, as "popularizing" economics or something similar. That is a sign they don't understand what is going on, that they don’t understand there is such a thing as “internet economics,” and also a sign they will not be effective competition. It's really about "the internet way of writing and communicating" vs. non-internet methods. The internet methods may or may not be popular, and may or may not be geared toward a wide audience, so they are not the same as popularizing. One point of the internet is to find an outlet for super-unpopular material. What's important right now is to develop internet methods of thinking and communicating, and not to obsess over reaching the largest possible numbers of people.

Naked mole-rat mortality rates defy Gompertzian laws by not increasing with age | eLife
> We compiled and analyzed a large compendium of historical naked mole-rat lifespan data with >3000 data points. Kaplan-Meier analyses revealed a substantial portion of the population to have survived at 30 years of age. Moreover, unlike all other mammals studied to date, and regardless of sex or breeding-status, the age-specific hazard of mortality did not increase with age, even at ages 25-fold past their time to reproductive maturity. This absence of hazard increase with age, in defiance of Gompertz’s law, uniquely identifies the naked mole-rat as a non-aging mammal, confirming its status as an exceptional model for biogerontology.

Magic-mushroom drug lifts depression in first human trial : Nature News & Comment
> Researchers from Imperial College London gave 12 people psilocybin, the active component in magic mushrooms. All had been clinically depressed for a significant amount of time — on average 17.8 years. None of the patients had responded to standard medications, such as selective serotonin re-uptake inhibitors (SSRIs), or had electroconvulsive therapy.

One week after receiving an oral dose of psilocybin, all patients experienced a marked improvement in their symptoms. Three months on, five patients were in complete remission.

Powerless Placebos | Slate Star Codex
The placebo effect is mostly regression to the mean... and: > Surfing Uncertainty had the the best explanation of the placebo effect I’ve seen. Perceiving the world directly at every moment is too computationally intensive, so instead the brain guesses what the the world is like and uses perception to check and correct its guesses. In a high-bandwidth system like vision, guesses are corrected very quickly and you end up very accurate (except for weird things like ignoring when the word “the” is twice in a row, like it’s been several times in this paragraph already without you noticing). In a low-bandwidth system like pain perception, the original guess plays a pretty big role, with real perception only modulating it to a limited degree (consider phantom limb pain, where the brain guesses that an arm that isn’t there hurts, and nothing can convince it otherwise). Well, if you just saw a truck run over your foot, you have a pretty strong guess that you’re having foot pain. And if you just got a bunch of morphine, you have a pretty strong guess that your pain is better. The real sense-data can modulate it in a Bayesian way, but the sense-data is so noisy that it won’t be weighted highly enough to replace the guess completely.

The right kind of fun?
> I don't know if playing Dungeons and Dragons (which was, from my perspective, mostly carefully reading books filled with charts and rules in anticipation of play, rather than playing) taught me to be able to study API documentation; but it might have. Playing with Hypercard and Cosmic Osmo and Myst might have taught me something about the simplicity of the secret text behind the world. Maybe people who play a lot of SpaceChem will do better in multithreaded programming. Maybe people who play a lot of FoldIt will do better in nanotech design. What I'm trying to say is the premise of "fun is what we do to recover from work" might not be the best place to start thinking about this.

What Can Be Done About Pedophilia? - The Atlantic
> “Sexual orientation” means different things in different contexts. When they say “sexual orientation,” most people mean a sexual interest that is inborn and unchangeable. No one chooses to be sexually attracted to children, although people do choose whether they act on their sexual attractions. Therapists have been attempting to turn pedophiles into non-pedophiles for a very long time, but no one has presented any objective evidence of any enduring change in sexual interests. People can learn self-control, people can take sex-drive-reducing medications, and people can learn how to live more healthy and productive lives, but we do not appear to be able to change the pedophilia itself.

A LessWrong Crypto Autopsy
> I think Moldbug's comment aged the best of all the ones on the original thread. He said he had no idea what was going to happen, but recommended buying ten bitcoins. If Bitcoin flopped, you were out $10. If it succeeded, you might end up with some crazy stratospheric amount (right now, ten bitcoins = $116,000). Sure, this depends on an assumption that Bitcoin had more than a 1/10,000 chance of succeeding at this level, but most people seemed to agree that was true.

This reminds me of eg the argument for cryonics. Most LWers believe there's a less than 10% chance of cryonics working. But if it does work, you're immortal. Based on the extraordinary nature of the benefits, the gamble can be worth it even if the chances of success are very low.
