Jerry Canterbury, paralyzed plaintiff in lawsuit that established ‘informed consent,’ dies at 78 - The Washington Post
> In 1959, at 19, he agreed to undergo a spinal surgery known as a laminectomy — a procedure expected to resolve a ruptured disc and that he said his doctor described as “no more serious than an ordinary, everyday operation.” The day after the surgery, Mr. Canterbury fell at the hospital while attempting to empty his bladder. Another operation followed. By the time he was discharged more than three months later, he was partially paralyzed in the legs and permanently incontinent. He would spend the rest of his life on crutches, then in a wheelchair and finally confined to a bed. Mr. Canterbury, who has died at 78, sued his surgeon, William T. Spence, accusing him of having failed to adequately warn him of the risks of his surgery. The physician ultimately prevailed, but a 1972 federal appeals court decision in the case became a foundation of the doctrine of informed consent and, by extension, the modern practice of medicine.

Visual release hallucinations - Wikipedia
> Mentally healthy people with significant vision loss may have vivid, complex recurrent visual hallucinations (fictive visual percepts). One characteristic of these hallucinations is that they usually are "lilliputian" (hallucinations in which the characters or objects are smaller than normal). The most common hallucination is of faces or cartoons.[4] Sufferers understand that the hallucinations are not real, and the hallucinations are only visual, that is, they do not occur in any other senses, e.g. hearing, smell or taste.[5][6] Among older adults (> 65 years) with significant vision loss, the prevalence of Charles Bonnet syndrome has been reported to be between 10% and 40%; a 2008 Australian study found the prevalence to be 17.5%.[2] Two Asian studies, however, report a much lower prevalence.[7][8] The high incidence of non-reporting of this disorder is the greatest hindrance to determining the exact prevalence; non-reporting is thought to be a result of sufferers being afraid to discuss the symptoms out of fear that they will be labelled insane.[6]

Asthma and obesity: does weight loss improve asthma control? a systematic review
> Weight loss in obese individuals with doctor-diagnosed asthma is associated with a 48%–100% remission of asthma symptoms and use of asthma medication. Published studies, furthermore, reveal that weight loss in obese asthmatics improves asthma control, and that especially surgically induced weight loss results in significant improvements in asthma severity, use of asthma medication, dyspnoea, exercise tolerance, and acute exacerbations, including hospitalizations due to asthma. Furthermore, weight loss in obese asthmatics is associated with improvements in level of lung function and airway responsiveness to inhaled methacholine, whereas no significant improvements have been observed in exhaled nitric oxide or other markers of eosinophilic airway inflammation.

Folie à deux - Wikipedia
> Folie à deux and its more populous cousins are in many ways a psychiatric curiosity. The current Diagnostic and Statistical Manual of Mental Disorders states that a person cannot be diagnosed as being delusional if the belief in question is one "ordinarily accepted by other members of the person's culture or subculture" (see entry for delusion). It is not clear at what point a belief considered to be delusional escapes from the folie à... diagnostic category and becomes legitimate because of the number of people holding it. When a large number of people may come to believe obviously false and potentially distressing things based purely on hearsay, these beliefs are not considered to be clinical delusions by the psychiatric profession and are labelled instead as mass hysteria.

> He’s most interested in the biology of aging, and specifically, how science has extended lifespans but hasn’t extended health spans at a corresponding rate. “Our experiences in life tell us that things get old and then they break,” Saffran said. “While that process seems perfectly normal and reasonable, it’s actually not necessary for biological systems to respond to age in this way.” He intends to investigate why this happens, and hopes to improve the health of our aging population in the process. Poised to eventually receive the same degree as his mentor, Kaplitt, Saffran is still sometimes in awe of the opportunities ahead of him. “I thought you have to be such a genius to do this kind of thing,” he says. “It’s the single greatest accomplishment of my life that is not directly connected to my daughter.”

Total knee replacement for athletes | Total joint replacement for athletes | Sports after total knee replacement | Sports after hip replacement The Stone Clinic
> The wearing out of plastic components most often occurs in mal position or mal tracking of the joint. Improved tracking is facilitated by strong muscles, better balance and more normal gait, all of which come from a strong core and strong trunk muscles. Total body fitness conditioning is the key to a long lasting joint replacement. Most modern knee replacements have plastic components that are interchangeable if worn out. So why limit an entire later lifetime of sports by the fear of them wearing out?

Finally to running: Running is the most common request we get from our athletes who need total knees. The data is that whether you run a mile or walk a mile, the total force on the joint is the same, since you take fewer steps when running. The peak forces are higher depending on the type of surface, the smoothness of the gait, the shoe wear and other factors. If you must run, run with great form on soft surfaces with new absorbent shoes. I have never seen a total knee become worn out from running nor have any of my peers who I have asked. In general cycling is a more logical sport as it limits the impact, but logic is not the reason we run.

Queens pursued more aggressive war policies - Marginal REVOLUTION
> We find that polities led by queens were more likely to engage in war than polities led by kings. Moreover, the tendency of queens to engage as aggressors varied by marital status. Among unmarried monarchs, queens were more likely to be attacked than kings. Among married monarchs, queens were more likely to participate as attackers than kings, and, more likely to fight alongside allies. These results are consistent with an account in which marriages strengthened queenly reigns because married queens were more likely to secure alliances and enlist their spouses to help them rule. Married kings, in contrast, were less inclined to utilize a similar division of labor. These asymmetries, which reflected prevailing gender norms, ultimately enabled queens to pursue more aggressive war policies.

Overcoming Bias : What TED Needs
> The most discouraging talk I heard was by Jim Yong Kim, President of the World Bank Group. He talked about how he fought the World Bank for years, because they insisted on using cost-effectiveness criteria to pick medical investments. He showed us pictures of particular people helped by less cost-effective treatments, daring us to say they were not worth helping. And he said people in poor nations have status-based “aspirations” for the same sort of hospitals and schools found in rich nations, even if they aren’t cost-effective, and who are we to tell them no. Now that he runs the World Bank (nominated by Obama in 2012), his priorities can now win more. The audience cheered. So sad.

Investigating the case of human nose shape and climate adaptation
Part of why different ancestral groups may have different nose sizes > We find that width of the nares is correlated with temperature and absolute humidity, but not with relative humidity. We conclude that some aspects of nose shape may indeed have been driven by local adaptation to climate. However, we think that this is a simplified explanation of a very complex evolutionary history, which possibly also involved other non-neutral forces such as sexual selection.

Restorative justice conferencing (RJC) using face-to-face meetings of offenders and victims: effects on offender recidivism and victim satisfaction - The Campbell Collaboration

The impact of RJCs on 2-year convictions was reported to be cost-effective in the 7 UK experiments, with up to 14 times as much benefit in costs of the crimes prevented (in London), and 8 times overall, as the cost of delivering RJCs. The effect of conferencing on victims’ satisfaction with the handling of their cases is uniformly positive (d = .327; p<.05), as are several other measures of victim impact.

Potent neuroprotection after stroke afforded by a double-knot spider-venom peptide that inhibits acid-sensing ion channel 1a
> In this study, we have demonstrated that inhibition of ASIC1a using Hi1a provides exceptional levels of neuroprotection even when the peptide is administered up to 8 h after stroke onset. Along with facilitating a substantially reduced level of penumbral damage, Hi1a is unique in providing some protection of the striatal core region, which is generally considered therapeutically unrecoverable owing to rapid and irreversible necrotic cell death ( .. Hi1a was neuroprotective even when administered 8 h after onset of ET-1–mediated MCAO. Although we did not determine the degree and duration of ET-1–mediated cerebral ischemia, previous studies have reported either complete or partial recovery of blood flow at 8 h after stroke (33–35). In this context, we have shown that the neuroprotection afforded by Hi1a is unlikely to result from a vasodilatory effect, given that it did not reverse ET-1–mediated vasoconstriction of isolated cerebral arteries

Total recall: the people who never forget | Science | The Guardian
> When I first spoke to McGaugh, he told me that the real question at the heart of HSAM wasn’t why his subjects remember, but why we forget. “The overall summary of all of this is that they’re bad forgetters,” he said. And forgetting is what humans do; often what we need to do. The title character in Jorge Luis Borges’s story Funes the Memorious, who acquires a perfect memory as the result of an accident, can no longer sleep because he is kept awake by the thousand mundane memories that whined like mosquitoes in his ears. The “peculiar mixture of forgetting with our remembering,” wrote William James, one of the founders of modern psychology, “is the very keel on which our mental ship is built.” “If we remembered everything,” he continued, “we should on most occasions be as ill off as if we remembered nothing.”

Manchester Liberalism - Wikipedia
> Manchester Liberalism are terms for the political, economic, and social movements of the 19th century that originated in Manchester, England. Led by Richard Cobden and John Bright, it won a wide hearing for its argument that free trade would lead to a more equitable society, making essential products available to all. Its most famous activity was the Anti-Corn Law League that called for repeal of the Corn Laws that kept food prices high. It expounded the social and economic implications of free trade and laissez-faire. The Manchester School took the theories of economic liberalism advocated by classical economists such as Adam Smith and made them the basis for government policy. The School also promoted pacifism, anti-slavery, freedom of the press, and separation of church and state.[1]

The Inescapable Gravity Of Biotech’s Key Clusters: The Great Consolidation Of Talent, Capital, & Returns | LifeSciVCLifeSciVC
> Biotech historians in the future might call it the “Great Consolidation of Talent and Capital.” While Silicon Valley quickly emerged in Tech a few decades ago as the nexus of all things IT and venture capital, in biotech it’s been far more geographically egalitarian in the past. San Francisco and Boston were clearly important leaders in the early decades of the field, but so were other biotech clusters: Seattle, San Diego, Raleigh, Philly/NJ, Colorado, etc… Most of these also had legacy Pharma or big Biotech footprints that were important for cultivation of talent. And great firms grew out of places well beyond Boston and San Francisco: early winners like Immunex, IDEC, Centacor, Medimmune, and Celltech, just to name a few – and firms like Celgene (San Deigo, NJ) and Amgen (Thousand Oaks) – all born in other geographies.

In recent years, this has changed – Boston and San Francisco are now the preeminent biotech clusters. And their gravity in the ecosystem is only getting stronger.

> Most teaching faculty—and psychiatrists in general—are understandably immersed in the practical demands of clinical work. At the same time, neuroscientists are immersed in cutting-edge research, which is often focused on molecular studies or animal models that may seem remote from the clinical reality of patient care. As seen in various sociopolitical contexts, each group may exist in its own echo chamber and communicate primarily (if not exclusively) with those who share similar perspectives. Opportunities for dialogue between researchers and clinicians are limited, all the more so because each group speaks a fundamentally different language. Thus, a major part of the challenge at hand is to facilitate communication across this deep cultural divide.

Reversible cerebral vasoconstriction syndrome - The Lancet Neurology
> Reversible cerebral vasoconstriction syndrome (RCVS) is characterised by severe headaches, with or without other acute neurological symptoms, and diffuse segmental constriction of cerebral arteries that resolves spontaneously within 3 months.1, 2 Manifestations are attributed to a transient disturbance of the regulation of cerebral arterial tone. Thunderclap headache—severe pain peaking in seconds—is usually the first symptom and typically recurs for 1–2 weeks.3, 4, 5 Ischaemic and haemorrhagic stroke are the major complications of the syndrome.5, 6, 7, 8, 9 In 2007, Calabrese and colleagues2 proposed the name RCVS and a set of diagnostic criteria to regroup all similar cases that had been reported since the 1970s under several other names (panel 1).10, 11, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 Since then, large case series of the syndrome have been published.5, 7, 8, 9, 24 In this Review, I focus on the clinical and radiological features of RCVS. I describe the clinical heterogeneity of the syndrome, appropriate investigations, and approaches to diagnosis (including possible differential diagnoses) and management. I aim to show that, although the pathological process is unknown and no specific diagnostic test or proven treatment is available, diagnosis is easy and an important step in the care of patients with RCVS.

8.4 Million New Yorkers Suddenly Realize New York City A Horrible Place To Live - The Onion - America's Finest News Source
> At 4:32 p.m. Tuesday, every single resident of New York City decided to evacuate the famed metropolis, having realized it was nothing more than a massive, trash-ridden hellhole that slowly sucks the life out of every one of its inhabitants. With audible murmurs of "This is no way to live," "What the hell am I doing here—I hate it here," and "Fuck this place. Fuck this horrible place," all 8.4 million citizens in each of the five boroughs packed up their belongings and told reporters they would...

The Rise of Evidence-Based Psychiatry - Scientific American Blog Network
> Osheroff won the lawsuit and, on appeal, settled with Chestnut Lodge outside of court. (Chestnut Lodge, a lovely historical landmark, eventually folded, was converted to upscale condos, and subsequently burned to the ground.) The case sparked a decades-long debate—one with “considerable spunk”—that captured the attention of the psychiatric community: “Has psychiatry reached the point where use of the psychodynamic model is viewed as malpractice when it is the exclusive treatment for serious me...

Choosing Psychiatry as a Career
> And the issues she brings up are common to almost everyone I know who decided on psych. ESPECIALLY if you switch from another specialty (like surgery or medicine) to psychiatry, you will probably go through the following mental process:
- I won’t be a “real” doctor, and I won’t ever use 95% of the information I spent four years toiling to learn in medical school.
- I’ll let down my family/friends/myself who thought I was going to go into a more prestigious specialty.
- Psychiatry doesn’t fit ...

I Talked To Some Trump Voters, Too – The Awl
> I spoke with Freddy O’Brien, a fifth-generation Bleaksviller who operates the bar. He told me he’d already talked about his support for Donald Trump to reporters from The New York Times, The Washington Post, USA Today, The Daily Mail, The Hindustan Times, and Stormfront so far that day, but that he’d be willing to do one more interview before hosting an opioid and pizza party for the high-school football team (which I assume is the linchpin of the community). I asked him why he disliked Hillar...

XYY syndrome - Wikipedia
> XYY syndrome is a genetic condition in which a human male has an extra male (Y) chromosome, giving a total of 47 chromosomes instead of the more usual 46. This produces a 47,XYY karyotype, which occurs every 1 in 1,000 male births.[1] Some medical geneticists question whether the term "syndrome" is appropriate for this condition[2] because its clinical phenotype is normal[2][3] and the vast majority of XYY males do not know their karyotype.[4]

Evolution: Diet drives primate brain size : Nature : Nature Research
> The primates that ate fruit had significantly larger brains than those that ate just leaves; and the more fruit they ate, the larger was the ratio of their brain size to their body size. The authors think this could be due to a combination of factors — one being the high nutritional content of fruit, another being cognitive adaptations that help the primates to forage for fruit. Such adaptations could allow them, for example, to extract fruit from protective skins. The team also found no correlation between brain size and the level of social complexity. This contradicts a widely accepted theory that states that large brains evolved to help primates manage large social networks.

Mapping of a non-spatial dimension by the hippocampal–entorhinal circuit : Nature : Nature Research
Pretty cool neuroscience. > The relationship between this general function and the specialized spatial activity patterns is unclear. A conceptual framework reconciling these views is that spatial representation is just one example of a more general mechanism for encoding continuous, task-relevant variables. Here we tested this idea by recording from hippocampal and entorhinal neurons during a task that required rats to use a joystick to manipulate sound along a continuous frequency axis. We found neural representation of the entire behavioural task, including activity that formed discrete firing fields at particular sound frequencies. Neurons involved in this representation overlapped with the known spatial cell types in the circuit, such as place cells and grid cells. These results suggest that common circuit mechanisms in the hippocampal–entorhinal system are used to represent diverse behavioural tasks, possibly supporting cognitive processes beyond spatial navigation.

Rare sighting reveals deep-sea octopus's unusual breakfast : Nature News & Comment
> Despite the fact that female H. atlanticus can grow up to 4 metres long, the species doesn’t require as much energy to stay alive as other octopuses do. “They’re running on a slower clock,” Haddock says. So eating low-calorie jellies works for them, especially if they focus on nutritious parts such as the stomach, an area that was missing from the egg-yolk jelly in the 2013 video.

Cancer Vegetarianism & Diet
Data suggesting that veganism is probably not protective against cancer, and that the main impact of diet on cancer is likely via obesity. > Among the diet-related factors, overweight/obesity convincingly increases the risks of several common cancers. After tobacco, overweight/obesity appears to be the most important avoidable cause of cancer in populations with Western patterns of cancer incidence. Among non-smoking individuals in these populations, avoidance of overweight is the most important...

Does usage of a parachute in contrast to free fall prevent major trauma?: a prospective randomised-controlled trial in rag dolls | SpringerLink
> It is undisputed for more than 200 years that the use of a parachute prevents major trauma when falling from a great height. Nevertheless up to date no prospective randomised controlled trial has proven the superiority in preventing trauma when falling from a great height instead of a free fall. The aim of this prospective randomised controlled trial was to prove the effectiveness of a parachute when falling from great height.

Should We Prescribe Light Therapy for Our Sleepy Parkinson Disease Patients? - NEJM Journal Watch
Bright light (for hour at a time) effective for sleepiness in PD. > Thirty-one Parkinson disease patients who were free of dementia, free of primary sleep disorders, and receiving optimized dopaminergic therapy were randomized to bright-light therapy or dim red light (control) therapy. Additionally, the baseline Epworth Sleepiness Scale was 12 or greater, indicating moderate to severe problems with alertness. Light (bright or dim) was administered in the morning and the evening for 1 hour each on a total of 14 days. Disease duration was relatively short for the participants in the bright-light therapy arm (5.9 years vs. 8.4 years for controls). Improvements in the primary outcome variable, the Epworth Sleepiness Scale score, favored the bright-light group (mean scores at baseline and at 4 weeks, 15.81 and 11.19 with bright light, 15.47 and 13.67 with dim light).
