A new Canadian guideline for managing opioid use disorders lays out the optimal strategies for the treatment of opioid addiction, including recommending opioid agonist treatment with buprenorphine-naloxone as the preferred first-line treatment. The guideline, published in CMAJ, was created for a wide range of health care providers to address an urgent need for evidence-based treatment of opioid use causing overdoses and death.
Children who experience persistent allergies to cow’s milk may remain shorter and lighter throughout pre-adolescence when compared with children who are allergic to peanuts or tree nuts, according to a retrospective chart review.
Columbia Engineers are the first to miniaturize dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip. This could lead to low-cost, portable sensing and spectroscopy in the field in real-time. ‘This is the first time a dual comb has been generated on a single chip using a single laser,’ says Electrical Engineering Prof. Michal Lipson who led the team with Applied Physics Prof. Alexander Gaeta.

A joint 7-year cohort study in both Singapore’s and New Zealand’s hospitals, revealed answers to key questions about the epidemiology of heart failure. The study set out how two distinct forms of heart failure previously considered similar in prevalence and risk of death, are in fact very different.
Researchers measured cortisol levels in the saliva of male undergraduate students as an indicator of HPA axis activity. They discovered that ‘dominance’ smiles, which challenge social standing and signal disapproval, were associated with higher HPA axis activity, such as increases in heart rate and salivary cortisol. Individuals perceiving ‘dominance’ smiles also took longer to return to their baseline cortisol levels after the stressful event. These physical responses to ‘dominance’ smiles mirror the influences of negative verbal feedback.
For people with heart failure, getting a seasonal influenza (flu) vaccine in a given year was associated with a 50 percent drop in the risk of death during flu season and a 20 percent drop in the risk of death during the rest of the year, according to research presented at the American College of Cardiology’s 67th Annual Scientific Session.
Twelve-foot metal poles with long outstretched arms dot a Midwestern soybean field to monitor an invisible array of light emitted by crops. This light can reveal the plants’ photosynthetic performance throughout the growing season, according to newly published research by the University of Illinois.
Hospitals participating in the American College of Cardiology’s Patient Navigator Program, showed significant improvement in implementing performance measures that help heart attack and heart failure patients transition from the hospital to home and keep them out of the hospital longer, according to research to be presented at the ACC’s 67th Annual Scientific Session.
Clinical studies by scientists at British American Tobacco indicate that when smokers switched completely from conventional cigarettes to glo, their exposure to certain harmful chemicals was significantly reduced. In some cases, the reductions were the same as those in smokers who quit altogether. These data suggest the potential of glo as a reduced-risk product. glo is a tobacco heating product designed to heat rather than burn tobacco. Tests show that glo vapour has around 90-95 percent less toxicants than smoke.
