Physician Reluctance to Intervene in Addiction: A Systematic Review.

Importance: The overdose epidemic continues in the US, with 107 941 overdose deaths in 2022 and countless lives affected by the addiction crisis. Although widespread efforts to train and support physicians to implement medications and other evidence-based substance use disorder interventions have been ongoing, adoption of these evidence-based practices (EBPs) by physicians remains low.

Objective: To describe physician-reported reasons for reluctance to address substance use and addiction in their clinical practices using screening, treatment, harm reduction, or recovery support interventions.

Clinging fauna associated with nearshore pelagic sargassum rafts in the Eastern Caribbean: Implications for coastal in-water harvesting.

Tropical Atlantic blooms of pelagic Sargassum species are associated with severe inundation events along the coasts of Caribbean and West African nations that cause extensive ecological and socioeconomic harm. The use of in-water harvesting as a management strategy avoids the plethora of challenges associated with shoreline inundations. Moreover, with a growing interest in the valorisation of this raw material, in-water harvesting provides the best opportunity to collect substantial amounts of 'fresh' sargassum that can be used in a variety of applications.

National Institute on Drug Abuse: Dissemination of Scientific Knowledge to Improve Adolescent Health.

The wide and effective dissemination of research findings is crucial to the mission of the National Institute on Drug Abuse (NIDA). This article describes NIDA dissemination efforts and resources that are available to inform clinicians, teens, families, and educators about youth and substance use. Resources that are available include content addressing facts about youth drug use, trends in use, and stigma, in addition to substance use disorder (SUD) prevention and treatment.

Removal of senescent cells reduces the viral load and attenuates pulmonary and systemic inflammation in SARS-CoV-2-infected, aged hamsters.

Older age is one of the strongest risk factors for severe COVID-19. In this study, we determined whether age-associated cellular senescence contributes to the severity of experimental COVID-19. Aged golden hamsters accumulate senescent cells in the lungs, and the senolytic drug ABT-263, a BCL-2 inhibitor, depletes these cells at baseline and during SARS-CoV-2 infection.
