Objective: We aimed to examine the dose-response associations between the number of steps per day and all-cause mortality among adults with prediabetes and diabetes.
Research Design And Methods: This prospective study used data from 1,194 U.S. adults with prediabetes and 493 with diabetes for whom accelerometer-derived steps per day could be retrieved. Mortality was ascertained through the National Death Index (February 25, 2019). Splines were used to assess the dose-response associations between steps per day and all-cause mortality.
Results: Over ∼9 years of follow-up, 200 adults with prediabetes and 138 with diabetes died. Nonlinear associations akin to an L shape were observed. We estimated an optimal dose of ∼10,000 steps per day to reduce the risk of all-cause mortality for both individuals with prediabetes and those with diabetes.
Conclusions: Accumulating more steps per day up to ∼10,000 steps per day may lower the risk of all-cause mortality of adults with prediabetes and diabetes.

Continuous high-soy protein soymilk intake affects ordinary walking speed in the Japanese pre-frail and frail elderly: a randomized controlled trial.

Background: To investigate whether continuous intervention using soymilk containing high soy protein improves physical frailty, a randomized controlled trial was conducted among the Japanese pre-frail and frail elderly.
Methods: Japanese pre-frail and frail elderly participants (n = 73) were randomly assigned to the high-soy protein and control groups, who then ingested soymilk containing 14.5 g/200 ml and 3.
Effects of chronic ethanol exposure on dorsal medial striatal neurons receiving convergent inputs from the orbitofrontal cortex and basolateral amygdala.

Alcohol use disorder is associated with altered function of cortical-amygdala-striatal circuits such as the orbitofrontal cortex (OFC), basolateral amygdala (BLA) and their connections to the dorsal medial striatum (DMS) shown to be involved in goal-directed actions. Using retrobead tracing, we previously reported enhanced excitability of DMS-projecting OFC neurons in mice following 3-to-7-day withdrawal from chronic intermittent ethanol (CIE) exposure. In the same animals, spiking of DMS-projecting BLA neurons was decreased at 3-days post-withdrawal followed by an increase in firing at 7- and 14-days.

Objective: Lower limb malalignment can complicate symptoms and accelerate knee osteoarthritis (OA), necessitating consideration in study population selection. In this study, we develop and validate a deep learning model that classifies leg alignment as "normal" or "malaligned" from knee antero-posterior (AP)/postero-anterior (PA) radiographs alone, using an adjustable hip-knee-ankle (HKA) angle threshold.
Material And Methods: We utilized 8878 digital radiographs, including 6181 AP/PA full-leg x-rays (LLRs) and 2697 AP/PA knee x-rays (2292 with positioning frame, 405 without).
Barriers to and enablers of physical activity and its association with daily steps after hospitalisation for a COPD exacerbation: what patients say matters.

Introduction: Exacerbations of COPD decrease physical activity. Physical activity interventions after these events are desirable but have had mixed results. Understanding the barriers to and enablers of physical activity may help to improve the results of these interventions.

Purpose: This paper describes the data collection and management methods for the Cancer Prevention Study-3 (CPS-3) Accelerometry Substudy, a nested cohort of device-based physical activity and sedentary time data.
Participants: US-based CPS-3 participants (initially enrolled 2006-2013) who completed the 2018 follow-up survey and had a valid email address were invited to the Accelerometry Substudy (n=109 780). Among the 23 111 participants who registered and were shipped an ActiGraph GT3X+ accelerometer, 21 219 participants returned the device with a complete wear log (91.
