The effect of incline walking on lower extremity and trunk mechanics in older adults.

Older adults are at an increased risk of developing knee osteoarthritis. High internal knee abduction moment during daily activities may elevate the risk of knee osteoarthritis. Incline walking exercise has been found to decrease knee abduction moment in healthy young adults.

Zenker's Per-Oral Endoscopic Myotomy (Z-POEM): The Ideal First Line Therapy for Treatment of Zenker's Diverticulum.

Objective: Zenker's diverticulum is a mucosal herniation at the pharyngoesophageal junction. While open surgical myotomy is the conventional treatment, robust evidence on third-space flexible endoscopic myotomy is lacking. We assessed safety, effectiveness and patient-reported outcomes of per-oral endoscopic myotomy (Z-POEM) in the largest reported single-centre experience with this technique.

Has lake brownification ceased? Stabilization, re-browning, and other factors associated with dissolved organic matter trends in eastern Canadian lakes.

The increase in dissolved organic carbon (DOC) concentrations in freshwater systems has received considerable attention due to its implications for drinking water treatment and numerous limnological processes. While past studies have documented the influence of recovery from acidification and climate change on long-term DOC trends, the emerging importance of these explanatory factors remains less understood. In addition, few studies have followed up on recent trends in sites that have undergone increases in DOC.

Cumulative Psychosocial and Health Disparities in US Adolescent Cigarette Smoking, 2002 to 2019.

Background: Understanding disparities in adolescent cigarette smoking is important for effective prevention.

Methods: We investigated disparities in adolescent smoking based on cumulative reported psychosocial/health risk among respondents ages 12-17 years in the US National Survey of Drug Use and Health from 2002 to 2019. Multivariable regression estimated associations of cumulative risk, survey years, and their interaction predicting past-month and daily smoking.
