Article Synopsis
  • Hamstring strain injuries (HSIs) are common in NFL players, particularly affecting positions like wide receivers and defensive backs, with the biceps femoris being the most frequently injured muscle.
  • A study analyzed 180 acute HSIs from the 2018-2019 NFL season to explore the relationship between player characteristics, clinical exams, and MRI findings regarding injury severity and time missed from games.
  • Findings indicated that nearly half of the injuries were moderate (BAMIC grade 2), with specific locations on the biceps femoris and semimembranosus being the most affected, and MRI detected abnormalities in the sciatic nerve in some cases.

Background And Purpose: Falls are the leading cause of morbidity and mortality among US older adults and result in considerable medical and social consequences. Community-based screenings are a type of intervention that provides accessible fall risk screening and education at no cost to the participants. However, little is known about whether or how participants change behavior after screening events.

Article Synopsis
  • - The article highlights how training-related injuries in the U.S. Army can impact military readiness and discusses the changing demographics and training characteristics of recruits during basic combat training (BCT) between 2002 and 2007.
  • - A study analyzed data from 368,102 first-time trainees, finding an increase in annual BCT starts and a shift in the male-to-female ratio, age, and body mass index across the years.
  • - The study suggests that variations in trainee characteristics should be further examined for their potential effects on BCT injury rates and emphasizes the importance of accurate administrative data collection for research purposes.

Article Synopsis
  • A significant portion of U.S. Army basic combat training participants—about 25% of men and 50% of women—sustain injuries, highlighting the need for injury prevention strategies that consider associated human and economic costs.
  • This study systematically reviews literature on risk factors for training-related injuries using original peer-reviewed studies published since 1990, considering a total of 19 studies in its analysis.
  • Strong or moderate evidence indicates that older age, a history of smoking, and lower physical activity levels before training increase injury risk for male trainees, while evidence related to female trainees remains limited and inconsistent.

In 2009, after resident calls regarding an odor, the Vermont Department of Health and state partners responded to 2 scenarios of private drinking water contamination from utility poles treated with pentachlorophenol (PCP), an organochlorine wood preservative used in the United States. Public health professionals should consider PCP contamination of private water if they receive calls about a chemical or gasoline-like odor with concurrent history of nearby utility pole replacement.

Background: Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) persist in the environment and are found in relatively high concentrations in animal livers. Studies in humans have reported inconsistent associations between PFOA and liver enzymes.

Objectives: We examined the cross-sectional association between serum PFOA and PFOS concentrations with markers of liver function in adults.
