OSA Patients: Slow-Release Morphine May Be Safe for Some
A 40-mg dose of slow-release morphine may be safe for non-severely obese patients with obstructive sleep apnea (OSA), researchers in Australia report. "Slow-release morphine did not seem to be the OSA of the men in our study." For most of the men, there were no differences in breathing during sleep whether they received oral 40-mg slow-release morphine or placebo, "said Dr. David Wang.
Heart Disease Clinical Trials: Not Enough Women are Included
Women are underrepresented in clinical trials for heart failure, coronary artery disease and acute coronary syndrome but proportionately or overrepresented in trials for hypertension, atrial fibrillation and pulmonary arterial hypertension, when compared to incidence or prevalence of women within each disease population, according to a study in the Journal of the American College of Cardiology.
Cholera Epidemics In Yemen: Lack of Preparedness and Insecurity Hampered Response
Between April 27, 2017 and July 1, 2018, more than one million suspected cases of cholera in two waves were reported in Yemen, which had been declared a high-level emergency by the United Nations in 2015. Humanitarian organizations implemented a robust response to cholera despite numerous challenges including famine-like conditions, active civil conflict and destroyed health infrastructure within a shrinking humanitarian space in Yemen.
New Sex Chromosome: Results of 30 Years of Experimental Evolutionary Project
Researchers report new findings of an experimental evolutionary project that ran for 30 years on the genomic mechanisms of sex determination in swordtail fish.
PADN-5: Ablation Reduces Pulmonary Hypertension in HF
Patients with combined pre and postcapillary pulmonary hypertension (CpcPH) secondary to left-sided heart failure (HF) who underwent a pulmonary artery denervation (PADN) procedure had significant improvements in hemodynamic and clinical outcomes at 6 months, compared with patients who underwent a sham procedure, in the PADN-5 trial.
Additional Testing Reduced with Point-of-Care Flu Testing, Study
Point-of-care influenza testing in emergency departments reduces chest x-rays and blood tests but not antibiotic use, according to a systematic review.
Mental Health May Take Same Toll on Health as Smoking and Obesity
An annual physical typically involves a weight check and questions about unhealthy habits like smoking, but a new study suggests health care providers may be overlooking a critical question: Are you depressed or anxious?
Enzyme's Unfrozen Adventure: In Crystallo Protein Thermodynamics
Researchers a have reported the first in crystallo thermodynamic analysis of copper amine oxidase catalysis using a non-cryocooled technique. The method, which analyzes protein crystals coated with a water-soluble polymer, rather than cryogenically cooled crystals, can be temperature-controlled, allowing for conformational changes to be monitored over a range of temperatures. Additionally, the conditions show parallels with the cytosol, meaning that the approach could provide a useful model for protein behavior in cells.
Study: Workplace 'Resilience' Programs Might Not Make Any Difference
Workplace resilience programmes, designed to bolster mental health and wellbeing, and encourage employees to seek help when issues arise, might not make any difference, suggests research published online in Occupational & Environmental Medicine.
Sports Compression Stockings a Winning Advantage: Performance Enhancer
A scientist from James Cook University in Australia has found sports compression stockings are so effective they might be considered performance enhancers for soccer players.
Protein Clumps Damage Cells in Parkinson's, Mechanism Uncovered
Biologists studying Parkinson's disease have long hoped to solve the mystery of the telltale "clumps." Scientists want to know how clumps of misfolded proteins damage brain cells and contribute to the disease.
