Adjunctive Bright Light Therapy for Bipolar Depression: A Randomized Double-Blind Placebo-Controlled Trial Sit, D. K., McGowan, J., Wiltrout, C., Diler, R. S., Dills, J., et al. (2017). Adjunctive bright light therapy for bipolar depression: A randomized double-blind placebo-controlled trial. American Journal of Psychiatry. doi:10.1176/appi.ajp.2017.16101200 Objective: Patients with bipolar disorder have recurrent major depression, residual mood symptoms, and limited treatment options. Building on promising pilot data, the authors conducted a 6-week randomized double-blind placebo-controlled trial to investigate the efficacy of adjunctive bright light therapy at midday for bipolar depression. The aims were to determine remission rate, depression symptom level, and rate of…

The Relationship of E-Cigarette Use to Cigarette Quit Attempts and Cessation: Insights From a Large, Nationally Representative U.S. Survey David T Levy, PhD, Zhe Yuan, MS, Yuying Luo, MS, David B Abrams, PhD; The Relationship of E-Cigarette Use to Cigarette Quit Attempts and Cessation: Insights From a Large, Nationally Representative U.S. Survey. Nicotine & Tobacco Research. https://doi.org/10.1093/ntr/ntx166 Objectives While cessation from cigarettes is a top priority for public health, controversy surrounds the role of e-cigarettes for quitting cigarettes. This study examines the role of e-cigarettes in quit attempts and 3-month cigarette abstinence using a large, recent nationally representative US sample. Methods Data…

Hot Topic: Mind-Body Therapies Dramatically Reduce Pain in Hospital Patients

Jackie Werner Hot Topics in Research, Neurology, Psychology and Psychiatry

Randomized Controlled Trial of Brief Mindfulness Training and Hypnotic Suggestion for Acute Pain Relief in the Hospital Setting Garland EL, Baker AK, Larsen P, et al. Randomized controlled trial of brief mindfulness training and hypnotic suggestion for acute pain relief in the hospital setting. Journal of General Internal Medicine. 2017. https://doi.org/10.1007/s11606-017-4116-9. Background Medical management of acute pain among hospital inpatients may be enhanced by mind-body interventions. Objective We hypothesized that a single, scripted session of mindfulness training focused on acceptance of pain or hypnotic suggestion focused on changing pain sensations through imagery would significantly reduce acute pain intensity and unpleasantness compared to…

Nutritional and Dietary Interventions for Autism Spectrum Disorder: A Systematic Review Sathe N, Andrews JC, McPheeters ML, Warren ZE. Nutritional and dietary interventions for autism spectrum disorder: A systematic review. Pediatrics. 2017. doi: 10.1542/peds.2017-0346 CONTEXT: Children with autism spectrum disorder (ASD) frequently use special diets or receive nutritional supplements to treat ASD symptoms. OBJECTIVES: Our objective was to evaluate the effectiveness and safety of dietary interventions or nutritional supplements in ASD. DATA SOURCES: Databases, including Medline and PsycINFO. STUDY SELECTION: Two investigators independently screened studies against predetermined criteria. DATA EXTRACTION: One investigator extracted data with review by a second investigator….

Largest GWAS of PTSD (N=20 070) yields genetic overlap with schizophrenia and sex differences in heritability Duncan L,E., Ratanatharathorn A, Aiello A,E., et al. Largest GWAS of PTSD (N=20thinsp]070) yields genetic overlap with schizophrenia and sex differences in heritability. Mol Psychiatry. 2017. The Psychiatric Genomics Consortium-Posttraumatic Stress Disorder group (PGC-PTSD) combined genome-wide case–control molecular genetic data across 11 multiethnic studies to quantify PTSD heritability, to examine potential shared genetic risk with schizophrenia, bipolar disorder, and major depressive disorder and to identify risk loci for PTSD. Examining 20 730 individuals, we report a molecular genetics-based heritability estimate (h2SNP) for European-American females of 29%…

FDA approves first drug to treat tardive dyskinesia Food and Drug Administration, U.S. Department of Health and Human Services. (2017). FDA approves first drug to treat tardive dyskinesia. Retrieved from https://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm552418.htm. The U.S. Food and Drug Administration today [April 11, 2017] approved Ingrezza (valbenazine) capsules to treat adults with tardive dyskinesia. This is the first drug approved by the FDA for this condition. Tardive dyskinesia is a neurological disorder characterized by repetitive involuntary movements, usually of the jaw, lips and tongue, such as grimacing, sticking out the tongue and smacking the lips. Some affected people also experience involuntary movement of the…

Hot Topics: Training Medical Students to Organize Needle Exchange Programs

Jackie Werner Hot Topics in Research, Substance Use Disorders

Students as effective harm reductionists and needle exchange organizers Barbour K, McQuade M, Brown B. Students as effective harm reductionists and needle exchange organizers. Substance Abuse Treatment, Prevention, and Policy. 2017;12(15). http://dx.doi.org/10.1186/s13011-017-0099-0. Background Needle exchange programs are safe, highly effective programs for promoting health among people who inject drugs. However, they remain poorly funded, and often illegal, in many places worldwide due to fear and stigma surrounding drug use. Continued advocacy, education, and implementation of new needle exchanges are thus essential to improve public health and reduce structural inequality. Commentary We argue that students, and especially professional and graduate students,…

Hot Topics: Common Gene Sets Link Bipolar Disorder, Major Depression, and Schizophrenia

Jackie Werner Hot Topics in Research, January, Mood Disorders, Psychology and Psychiatry, Schizophrenia

Consistently altered expression of gene sets in postmortem brains of individuals with major psychiatric disorders Darby M,M., Yolken R,H., Sabunciyan S. Consistently altered expression of gene sets in postmortem brains of individuals with major psychiatric disorders. Transl Psychiatry. 2016;6:e890. http://dx.doi.org/10.1038/tp.2016.173. The measurement of gene expression in postmortem brain is an important tool for understanding the pathogenesis of serious psychiatric disorders. We hypothesized that major molecular deficits associated with psychiatric disease would affect the entire brain, and such deficits may be shared across disorders. We performed RNA sequencing and quantified gene expression in the hippocampus of 100 brains in the Stanley…

Finding the Why, Changing the How: Improving the Mental Health of Medical Students, Residents, and Physicians

PJ Grier Hot Topics in Research, Psychology and Psychiatry, Research Commentary, September

Finding the Why, Changing the How: Improving the Mental Health of Medical Students, Residents, and Physicians The poor mental health of residents, characterized by high rates of burnout, depression, and suicidal ideation, is a growing concern in graduate medical education. Research is needed to gain a deeper understanding of the sources of distress as well as the sources of sustenance in residency training. The study by Mata and colleagues contributes significantly to this understanding. In addition to this line of research, however, studies are needed that assess the impact of interventions to help residents deal more effectively with the stress…
