Physician burnout, depression can lead to major medical errors: Study

Health
Does your doctor’s mental health and well-being affect the care you receive? A new study says yes -- burnout, fatigue and depression may affect major medical errors. Medical errors contribute to an estimated 100,000 to 200,000 deaths per year, according to the Institute of Medicine. Burnout -- defined as emotional exhaustion or depersonalization -- occurs in more than half of doctors, according to the study. Researchers surveyed physicians across the country to understand the relationship between burnout and major medical errors in their careers. Their findings, published in Mayo Clinic Proceedings, suggest burnout, by itself, plays a large role in errors. Other independent factors affecting errors include the perceived safety of the workplace, physician fatigue and physician men...
Dozens of genetic risk factors found for depression

Dozens of genetic risk factors found for depression

Technology
A major new study which has identified 44 genetic risk factors for depression has the "potential to revitalise treatment", scientists have said. The international study, co-led by King's College London, is the largest carried out into a genetic basis for depression and involved more than 200 scientists.Seven data sets were combined, covering 130,000 sufferers.Among the 44 genetic variants identified, 30 are newly discovered.Previous studies have struggled to identify more than a handful. A significant number were linked to the targets of current antidepressant medications.Researchers said that all humans carry some of the 44 risk factors, and that the genetic basis for depression is shared with other psychiatric disorders such as schizophrenia.A higher body mass index is also linked to an ...
Sleeping in rooms with even a little light can increase risk of depression: Study

Sleeping in rooms with even a little light can increase risk of depression: Study

Health
Exposure to light at night, even at very low levels, has been linked to an increased risk of depression, according to a study published this month in the American Journal of Epidemiology. In general, nighttime light has been shown to disrupt internal sleep/wake cycles, which is an ever-growing concern as more people are using their phones and tablets in bed, or leaving the TV on as they sleep. But the new report goes further, measuring bedroom exposure to low levels of nighttime light using a portable light meter attached to the bed. Researchers followed nearly 900 elderly people in Japan for two years and assessed symptoms of depression and tested sleep/wake patterns throughout the night. They took into account weight, smoking or drinking habits, income level and medication use. Histo...
Depression linked to reduced levels of amino acid: study

Depression linked to reduced levels of amino acid: study

Health
Feb. 21 (UPI) -- Reduced levels of an amino acid found in blood samples have been linked to major depressive disorder, according to a new study in Finland.Researchers with the University of Eastern Finland and Kuopio University Hospital studied 99 adults aged 20-71 with diagnosed major depressive disorder and 253 non-depressed control adults in a report published Wednesday in the Journal of Affective Disorders.The body uses the amino acid arginine to produce nitric oxide, which is a mediator for the nervous system and immune defender, and plays a role in vascular regulation. Reduced arginine is also a known risk factor of cardiovascular diseases."It is possible that depression-induced inflammatory responses lead to reduced arginine levels," doctoral student Toni Ali-Sisto, the lead author ...
Is social media causing childhood depression?

Is social media causing childhood depression?

Technology
Rangan Chatterjee is a GP and says he has seen plenty of evidence of the link between mental ill-health in youngsters and their use of social media. One 16 year-old boy was referred to him after he self-harmed and ended up in A&E."The first thought was to put him on anti-depressants but I chatted to him and it sounded like his use of social media was having a negative impact on his health."So Dr Chatterjee suggested a simple solution - the teenager should attempt to wean himself off social media, restricting himself to just an hour before he went to bed. Over the course of a few weeks, he should extend this to two hours at night and two in the morning."He reported a significant improvement in his wellbeing and, after six months, I had a letter from his mother saying he was happier at s...
