How to Solve Homicide Crimes

by William Yates, M.D. in Brain Posts

Homicide rates in the U.S. represent a significant public health challenge. Homicide is a top ten leading cause of death in many groups in the U.S.One method to reduce homicide rates is to quickly identify and arrest individuals who have committed homicide. This is due to the fact that individuals committing homicide have a high rate of future homicide.A recent study from Michigan State University and Indiana University examined characteristics of U.S. police departments that have high rates of ........

Smartphones and Sleep Data: Data Mining

by William Yates, M.D. in Brain Posts

Smartphones contribute a treasure trove of data that is likely to expand our knowledge of a variety of human behaviors.An example of this is a recent study published in Science Advances by a research team from the University of Michigan.The University of Michigan team developed a smartphone app called ENTRAIN and then used the app to collect sleep data on subjects from around the world.They came up with some very interesting findings including the following:The time of going to sleep appears mor........

Ketamine Metabolite Linked to Rapid Antidepressant Effect

by William Yates, M.D. in Brain Posts

Model of crytalized ketamine moleculeStandard antidepressant therapies typically take two weeks or more to begin to act.Ketamine is an anesthetic drug recently demonstrated to have a rapid antidepressant effect.The mechanism for this effect is unknown. A recent mouse study of ketamine and metabolites of ketamine show some potentially groundbreaking insight for the treatment of depression.This study found these significant findings:Ketamine like most organic compounds is made of boty an R an........

"The Biggest Loser": Long-term Effects

by William Yates, M.D. in Brain Posts

Yesterday I posted a link to a New York Times article that posted a summary outcome in fourteen participants in TV's "The Biggest Loser" show.The study found a trend towards post-show weight gain for 13/14 of the participants.Four participants actually gained so much weight that after six years they weighed more than before participating in the show.A key finding from the study was this weight gain could be explained by a metabolic response resulting in up to 800 calories less burned daily ........

Delirium and Aortic Valve Surgery Outcome

by William Yates, M.D. in Brain Posts

Delirium is an acute confusional state that is common in elderly hospitalized patients.I think of it light a sign of acute brain failure requiring aggressive attentional for detection and treatment of any reversible underlying causes.Delirium in elderly hospitalized patients is a marker for poor outcome in a variety of medical and surgical subjects.A recent study published by a Norwegian team found effects on outcome for delirium following surgical aortic valve replacement. The key findings from........ Read more »

Long-term antibiotics for those with chronic symptoms that may or may not be related to Lyme disease

by Microbe Fan in Spirochetes Unwound

A Lyme disease study published a few weeks ago in the New England Journal of Medicine has received a lot of coverage in the press.  According to the abstract of the study, Berende and colleagues conducted a randomized placebo-controlled clinical trial to test the effectiveness of long-term antibiotics in treating "longer-term" symptoms "attributed" to Lyme disease.As many readers of this blog know, treatment of Lyme disease is a controversial topic.  Antibiotics are effective in treati........

Dr. Kudenchuk is Misrepresenting ALPS as 'Significant'

by Rogue Medic in Rogue Medic

This study was very well done, but it was not designed to provide valid information about the effects of amiodarone or lidocaine on witnessed arrests or on EMS Witnessed arrests. Maybe the authors were overconfident.

In resuscitation research, we have abundant evidence that overconfidence is much more common than improvements in outcomes.... Read more »

Maintained disomic chromosome 17 as a diagnostic marker for BHD-associated chromophobe RCC

by Joana Guedes in BHD Research Blog

Renal cell carcinomas (RCCs) can be life-threatening and although mostly sporadic, approximately 5% are associated with genetic conditions such as BHD. Early identification of families carrying cancer-predisposing mutations enables access to regular screening and earlier treatment. However, it can be difficult to distinguish between sporadic and inherited RCC based on standard immunohistological analysis. New research from Kato et al. (2016) assessed whether variability in the chromosomal status........ Read more »

Treat the pain... or treat the depression? Carpal Tunnel Syndrome management

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Carpal tunnel syndrome is a very common pain disorder associated with compression of the median nerve at the carpal tunnel. Approximately 139 women and 67 males per 100,000 people will report this problem over the course of one year, although this depends on the definition used. The problem with CTS is not only that it is common, but also that it affects function - it is really difficult to carry out normal daily life with a numb or tingly hand, poor grip strength (particularly in the fingertips........

A Weighty Problem……

by anthony.mccluskey12 in Zongo's Cancer Diaries

Amid all of the hoopla that accompanied last week’s press reports about the new Alcohol Consumption Guidelines, something else slipped under the radar.  CRUK released a statement, which didn’t receive quite the same level of media hysteria.  Which is surprising, frankly, because it involved another popular subject.  One which, if it had been released at […]...

Turning to the “Infected Jelly” to Treat Ebola

by Pranab Chatterjee in Scepticemia

The NEJM has come out with a very interesting paper: Evaluation of Convalescent Plasma for Ebola Virus Disease in Guinea.

Few articles, however, looked…... Read more »

If Colistin Goes, Can Carbapenems be Far Behind?

by Pranab Chatterjee in Scepticemia

I wrote about the disaster-in-the-making discovery of transmissible resistance to colistin, a last resort antibiotic, when the Lancet Infectious Diseases published a paper based on data coming out from surveillance in China. At that point of time, the isolation of the transmissible gene providing resistance (mcr1 gene) gained a lot of attention. Maryn McKenna’s blog post went…... Read more »
