Accuracy of wrist-worn activity trackers for measuring steps in patients after major abdominal surgery: A validation study.

Background: Wearable activity trackers provide a simple and objective measurement of postoperative mobilization. However, few have validated the accuracy of trackers in patients after major abdominal surgery.

Objective: To examine the accuracy of wrist-worn activity trackers to measure steps of patients in early mobilization after major abdominal surgery, and to explore the influence of clinical variables and gait parameters on the accuracy of trackers.

A serological survey of COVID-19 among predominantly aboriginal residents of a tourist island in southern Thailand.

Background: The current survey describes the seroprevalence, history of coronavirus disease 2019 (COVID-19), and vaccination status among predominantly aboriginal residents on a tourist island in southern Thailand. This information can be translated into COVID-19 vaccination and control plans for this population.

Methods: We implemented questionnaire interviews and collected blood samples from 249 residents of Lipe Island, Satun Province, in January 2022.

Availability of family care resources, type of primary caregiving and home death among the oldest-old: A population-based retrospective cohort study in China.

Place of death is one of the quality indicators for end-of-life (EOL) care, and most people prefer to die at home. This study investigated the association between availability of family care resources, type of primary caregiving and home death. A sample of 21,677 deceased oldest-old consisting of 5,224 octogenarians, 8,489 nonagenarians, and 7,964 centenarians, was derived from the 1998-2018 Chinese Longitudinal Healthy Longevity Survey.

p38MAPK and ERK promote nitric oxide production in cultured human retinal pigmented epithelial cells induced by high concentration glucose.

Increased nitric oxide (NO) has been correlated with diabetic retinopathy. In this study we investigated the cell injury, production of NO in retinal pigment epithelial (RPE) cells exposed to increased glucose concentration, and its molecular mechanism involved. Cultured human RPE cells (ARPE-19) were exposed for 4 days with normal blood glucose concentration (5.
