Whole-body angular momentum during stair ascent and descent in individuals with and without knee osteoarthritis.

Given the higher fall risk and the fatal sequelae of falls on stairs, it is worthwhile to investigate the mechanism of dynamic balance control in individuals with knee osteoarthritis during stair negotiation. Whole-body angular momentum ([Formula: see text]) is widely used as a surrogate to reflect dynamic balance and failure to constrain [Formula: see text] may increase the fall risk. This study aimed to compare the range of [Formula: see text] between people with and without knee osteoarthritis during stair ascent and descent.

Effectiveness of the primary Bacillus Calmette-Guérin vaccine against the risk of Mycobacterium tuberculosis infection and tuberculosis disease: a meta-analysis of individual participant data.

Background: Tuberculosis vaccine trials using disease as the primary endpoint are large, time consuming, and expensive. An earlier immunological measure of the protection against disease would accelerate tuberculosis vaccine development. We aimed to assess whether the effectiveness of the Bacillus Calmette-Guérin (BCG) vaccine for prevention of Mycobacterium tuberculosis infection was consistent with that for prevention of tuberculosis disease.

Survival Differences in Asian and Hispanic Patients With In-Hospital Cardiac Arrest.

Background: Although they are fast-growing populations in the United States, little is known about survival outcomes of Hispanic and Asian patients after in-hospital cardiac arrest.

Methods And Results: In Get With The Guidelines-Resuscitation, we identified Asian, Hispanic, and White adults with in-hospital cardiac arrest during 2005 to 2023. Using multivariable models, we compared rates of survival to discharge separately for Asian and Hispanic patients versus White patients, as well as rates of sustained return of spontaneous circulation for ≥20 minutes and favorable neurologic survival as secondary outcomes.

Out-of-Pocket Expenses and Postoperative Therapy After Open Reduction Internal Fixation of a Distal Radius Fracture.

Background: Postoperative hand therapy after surgery for distal radius fractures is associated with improved functional outcomes. However, financial impediments can be a potential barrier to adherence to postoperative care requirements. The aim of this study is to evaluate the relationship among the surgical and therapy out-of-pocket (OOP) expenses and therapy visits after operative treatment of a distal radius fracture.

Effect of Health Literacy on Antiviral Treatment of Hepatitis B: Instrumental Variable Analysis.

Background: China is a country with a high burden of hepatitis B (Hep B) but a low treatment rate. One of the key reasons for the low treatment rate is the inadequate health literacy (HL) of the people, which may affect the awareness and knowledge of Hep B and its treatment, as well as the ability to actively and correctly seek medical resources.

Objective: This study analyzed how HL contributed to the scale-up of antiviral treatment of Hep B in China.
