Neurology News, June 2014 Bipolar Patients in Integrated Systems May Need More-Intensive Care Primary care patients with bipolar disorder may require more intensive care, or better outreach with specialty mental health clinics, than is currently provided in a collaborative care system; this could occur if psychiatrists are integrated into the clinics either in person or via telemedicine. Psychiatric News, May 2014 Botox Shots May Help Bring Sustained Lifting of Depression Botox injections contribute to a strong and sustained alleviation of depression in psychiatric patients; two theories have been presented as to why botulinum toxin may have antidepressant effects: the facial feedback hypothesis which supports the concept that the facial musculature not only expresses but also regulates mood states, or the trigeminal neuromodulation, which is hypothesized to improve depression through glutaminergic mechanism. Clinical Psychiatry News, June 2014 Decreased Levels of Vitamin D Linked to Decreased Serotonin in Autism Patients Levels of 25-hydroxyvitamin D3, the precursor of calcitriol, have found to be lower in autistic individuals; calcitriol activates the transcription of tryptophan hydroxylase 2, a gene that converts tryptophan to serotonin in the brain, resulting in reduced serotonine in autistic brains, and simultaneously also inhibits the gene responsible for tryptophan hydroxilase 1, resulting in a decreased production of serotonine in the gut and other locations where it can promote inflammation. Life Extension, June 2014 Oral Naltrexone and Acamprosate Reduce Various Measures of Alcohol Consumption Acamprosate (a glutamine antagonist and gama-aminobutiric acid agonist) and oral naltrexone (an opioid antagonist) were about equally effective in preventing resumption of any drinking; naltrexone also was effective in reducing heavy drinking, but acamprosate was not. Nalmefene and topiramate are somewhat effective, but disulfiram is not. NEJM, July 2014 Damaged Mitochondria May Link Alcohol and Muscle Weakness Mitochondrial damage in muscle tissue may explain why chronic drinking leads to early fatigue in muscles, according to a study funded by the National Institute on Alcohol Abuse and Alcoholism.

Family Practice News, June 2014 Hormone Suppressor Seen Helping Breast-Cancer Patients Adding a hormone-suppressing shot (Goserelin) to the chemotherapy for some breast-cancer patients can reduce the risk of premature ovarian failure and increase the chances of fertility preservation – and potentially boost survival rates – according to a new study. American Society of Oncology Creatine Shows Promise in Huntington Disease The rate of atrophy in the brain’s cortex and striatum among pre-manifest Huntington disease carriers was slower among those who receive creatine than the placebo group, who experience progression, a trial has shown. Life Extension, June 2014 Gamma Tocopherol Protects Against Cognitive Impairment A study uncovered a protective effect for higher levels of the vitamin E subfractions gamma tocopherol, beta tocotrienol, and total tocotrienols against the risk of developing Alzheimer’s disease or mild cognitive impairment. Life Extension, June 2014 Topiramate Decreases Heavy Drinking The anticonvulsant topiramate reduces heavy drinking and increases abstinent days in alcohol-dependant individuals whose goal is to stop drinking, even in patients who are actively drinking.
