Here are studies, reports and stories that caught our eye in the last month.

Medical marijuana and the workplace: An article in WC Workers’ Compensation magazine covers the clinical and legislative significance of medical marijuana. As more states approve the use of medical marijuana, employers must consider how to handle claims when medical marijuana is prescribed for work-related injuries and policies related to work duties for those using  medical marijuana, the article says.

Liability Medicare Set-Asides on the horizon: An article in Claims Management says that the Centers for Medicare and Medicaid Services could review Liability Medicare Set-Asides. The article updates the latest movement on the issue and recommends current best practices for liability claims with Medicare beneficiaries.

New study on Alzheimer’s disease: In a report from JAMA Psychiatry, higher brain amyloid burden, an early indicator of Alzheimer’s disease, was associated with more frequent feelings of isolation, being left out and lacking companionship. These feelings could be associated with early brain changes in preclinical Alzheimer’s disease before the onset of mild cognitive impairment.

Help for those healing: As many as 70 percent of patients with cancer report increased anxiety, depression, fatigue and a poorer quality of life after chemotherapy. A study in the Journal of Clinical Oncology found improvements when patients took part in a web-based cognitive rehabilitation program.

Kids at risk: An analysis in JAMA Pediatrics found that pediatric hospitalizations for opioid poisonings increased almost two-fold from 1997 to 2012. Older adolescents had the highest hospitalization rates, but the largest percentage increase was among toddlers and preschoolers. Public health interventions, policy initiatives and consumer-product regulations are required to curb children’s exposure and misuse of the drugs.
