Violent Death Rates Increased After Traumatic Brain Injury

by William Yates, M.D. in Brain Posts

Anecdotal reports have linked traumatic brain injury with later violent death including death by suicide.Few large epidemiological studies have been published on this association.However, a recent Swedish population study published in JAMA Psychiatry provides valuable insight into this issue.Seena Fazel and colleagues from the University of Oxford, University College London and the Karolinksa Institute examined a large database of over 200,000 patients with TBI.Cases of TBI were identified from ........

Video Tip of the Week: PhenDisco, “phenotype discoverer” for dbGap data

by Mary in OpenHelix

The dbGaP, database of Genotypes and Phenotypes, repository at NCBI collects information from research projects that link genotype and phenotype information and human variation, across many different types of studies, providing leads on variation that may be important to understand clinical issues. Some of the data is publicly available de-identified patient information, and some of the […]... Read more »

Does Life Come In XXXS?

by Mark Lasbury in As Many Exceptions As Rules

Is there a minimum size for life? How would you measure it, cell volume or genome size? People do both. The current minimum example of life is Mycoplasma genitalium, at just 200 nm by 600 nm in well-fed cultures. M. genitalium also has the smallest known genome for a free-living organism (520 genes, we have about 27,000). Some organisms have fewer genes (137 or so) but are endosymbionts, so they can get away with trashing some of their DNA. New research shows that M. genitalium is a pathogenic o........ Read more »

Immunological effects from risperidone treatment in autism

by Paul Whiteley in Questioning Answers

The findings from Jai Eun Choi and colleagues [1] suggesting that use of the antipsychotic risperidone may impact on levels of certain cytokines - messenger cells of the immune system - in some cases of autism spectrum disorder (ASD) grabbed my attention recently. I've always been pretty interested in the complexity of the immune system when it comes to something like autism (see here) as well as the various examples of how many of the medications used to 'manage' aspects of autis........

The Devil Is In The Details…If You Can Get The Details Out

by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field

Over 75% of surveyed collegiate athletes, who believed they sustained a concussion in the past year, reported not seeking proper medical attention for that concussion. The most common reason athletes reported not seeking proper medical attention was not believing the concussion was severe enough to warrant stopping the activity to seek out a medical professional....

Gabapentin and pregabalin misuse

by DJMac in Recovery Review

  Gabapentin and pregabalin misuse are problems that are not going to go away. My post on gabapentin is one of the most-read on this site. While these are useful medicines, workers in drug treatment and support see patients regularly on gabapentin or pregabalin who have misused the drugs or who are misusing them. Guidance is [...]

Treating Sleep Problems Following Traumatic Brain Injury

by William Yates, M.D. in Brain Posts

Sleep problems are common following traumatic brain injury (TBI).In a previous post, I reviewed a study of the risk factors for sleep disorders following TBI.The most severe TBI is a risk factor for hypersomnia. Anxiety and depression following TBI increase risk for insomnia complaints.Few large studies of treatment for sleep problems after TBI exist. However, a recent manuscript outlined the potential benefit of treatment of sleep disorders in a series of 12 subjects.Catherine Wiseman-Hake........

Ketogenic diet and the valproate mouse model of autism

Stem Cell Discovery May Increase Efficiency of Tissue Regeneration

by beredim in Stem Cells Freak

Miguel Ramalho-Santos, PhDA new stem-cell discovery might one day lead to a more streamlined process for obtaining stem cells, which in turn could be used in the development of replacement tissue for failing body parts, according to UC San Francisco scientists who reported the findings in the current edition of Cell.The research builds on a strategy that involves reprogramming adult cells back to an embryonic state in which they again have the potential to become any type of cell.The efficiency ........

Attention Deficit Hyperactivity Disorder & Eating Disorders: Is There a Link?

by Tetyana in Science of Eating Disorders

Attention deficit hyperactivity disorder (ADHD), characterized by inattention, hyperactivity, and impulsivity, is a common childhood disorder. ADHD can often persist into adolescence and adulthood. The prevalence of ADHD is thought to be between 6-7% among children and adolescents and ~5% among adults (Willcutt, 2012).
Increasingly, evidence from multiple studies has pointed to comorbidity between ADHD and eating disorders (EDs). For example, one study found that young females with ADHD we........ Read more »

Researchers Develop iPSCs-Based Model for Insulin Resistance

by beredim in Stem Cells Freak

C. Ronald KahnIn 2012, Japanese biologist Shinya Yamanaka won a Nobel Prize for discovering the so-called induced pluripotent stem cells" (iPSCs), cells derived from normal adult cells that have the ability to differentiate into almost any other kind of cells. Now, researchers at Joslin Diabetes Center say they have created the first iPSCs line that offers a human model for insulin resistance, a key driver of type 2 diabetes.

Prenatal and neonatal blood mercury levels and autism

by Paul Whiteley in Questioning Answers

Acknowledging that some topics have the ability to furrow brows when it comes to autism research, mercury and autism is becoming something of a frequent talking point on this blog as a function of a whole slew of articles appearing in the peer-reviewed domain. If I were to [very tentatively] summarise the collected literature so far, it would be to say something like:Mosaic of mercury @ Wikipedia (i) there is quite a bit more research to be done on some sources of mercury being 'l........
