The paper by Michael Benrós and colleagues  talking about an "increased risk of subsequent autoimmune diseases in individuals with schizophrenia" caught my eye recently. Based on a trawl of the records of several thousands of people with "schizophrenia-like psychosis" or "individuals with autoimmune disease" derived from Danish nationwide registers (see here for some background), the authors were able to conclude that "Autoimmune diseases developed subsequently in 3.6% of people wi........

I have an awkward relationship with mathematical oncology, mostly because oncology has an awkward relationship with math. Although I was vaguely familiar that evolutionary game theory (EGT) could be used in cancer research, mostly through Axelrod et al. (2006), I never planned to work on cancer. I wasn’t eager to enter the field because I […]... Read more »
National Eating Disorder Awareness Week came and went (in the US, anyway). Posters were shared, liked, and tweeted. Pretty (but often misguided) infographics made the rounds on the internet. Local ED groups visited schools and college campuses to educate students about eating disorders. To, you know, increase awareness.
The thing is, awareness is not always a good thing. For one, as Carrie over at ED Bites mentioned, there’s a whole lot of misinformation masquerading as fact. An........ Read more »

The dissociative anesthetic and ravey club drug ketamine has been hailed as a possible “miracle” cure for depression. In contrast to the delayed action of standard antidepressants such as SSRIs, the uplifting effects of Special K are noticeable within an hour. “Experimental Medication Kicks Depression in Hours Instead of Weeks,” says the National Institute of Mental Health. NIMH has been bullish on ketamine for years now. Prominent researchers Duman and Aghajanian called it the “the mo........ Read more »
At the time of writing this post, the media is awash with two stories with an autism research slant to them. So we have the paper by Brian D’Onofrio and colleagues  talking about older, sorry, advancing paternal age and the risk of various conditions for offspring, including autism, and the paper by Sébastien Jacquemont and colleagues  on a female protective model for autism. Y'know these are serious pieces of research when the good old BBC (Auntie) puts it........ Read more »

Vascular compliance is a characteristic of the blood vessel wall to expand or contract with changes in pressure, and is reduced with aging or diseases like arteriosclerosis. Our goal was to investigate how hand-volume changes differ with age and to provide a simple non-invasive method to assess vascular compliance. We hypothesized that gravity-related, hand-wrist volume changes are greater in younger than in older healthy volunteers. Thirty-five healthy volunteers were classified into two age gr........

The RASopathies are a class of developmental disorders caused by a genetic mutation in the Ras signaling pathway and associated mitogen-activated protein kinases that control the cell cycle, differentiation and senescence. These diseases encompass a diverse set of clinical syndromes including neurofibromatosis type 1 and Noonan syndrome. Although the pathophysiological manifestations of these conditions are diverse, they share some common phenotypic features. The prevalence of pulmonary hyperten........ Read more »

Individuals with schizophrenia or bipolar disorder are at higher risk for obesity.This risk may be related to physical inactivity, diet or the weight gain commonly associated with psychotropic drug use.Few clinical trials for weight loss have targeted individuals with serious mental illness (SMI).

The "sunshine vitamin" that is vitamin D has cropped up quite a few times on this blog for all manner of reasons. The suggestion of a link (whatever that means) between vitamin D and the autism spectrum conditions has received the lion's share of coverage, be that in relation to measured levels of vitamin D (see here and see here) or more speculatively, the possible impact of something like deficiency of vitamin D to symptoms or physiology (see here and see here).

America has a problem. Some people are spouting the lie that vaccines can cause autism and other people are believing them.

Sometimes there’s no false equivalence; people […]... Read more »
