Health locus of control and associated factors among community-dwelling older adults: a cross-sectional descriptive study.

Background: To know the level of health locus of control (HLC) and investigate the factors associated with HLC among community-dwelling older adults.

Method: A total of 470 older adults completed the Multidimensional Health Locus of Control Scale, the Activities of Daily Living Scale, the Geriatric Depression Scale, and the Lubben Social Network Scale. Hierarchical multiple regression was used to explore the factors associated with HLC.

Recent Advances in Self-Powered Sensors Based on Ionic Hydrogels.

After years of research and development, flexible sensors are gradually evolving from the traditional "electronic" paradigm to the "ionic" dimension. Smart flexible sensors derived from the concept of ion transport are gradually emerging in the flexible electronics. In particular, ionic hydrogels have increasingly become the focus of research on flexible sensors as a result of their tunable conductivity, flexibility, biocompatibility, and self-healable capabilities.

A targetable OSGIN1 - AMPK - SLC2A3 axis controls the vulnerability of ovarian cancer to ferroptosis.

Despite advances in various chemotherapy regimens, current therapeutic options are limited for ovarian cancer patients. Oxidative stress-induced growth inhibitor 1 (OSGIN1), which is a tumor suppressor gene known to regulate the cellular stress response and apoptosis, is associated with ovarian cancer development. However, the underlying mechanisms involved in ferroptosis regulation have not been elucidated.

Ferroelectric Nematic Liquid Crystals Showing High Birefringence.

High birefringence nematic liquid crystals are particularly demanded for adaptive optics applications in the infrared spectrum because it enable a thinner cell gap for achieving fast response time and improved diffraction efficiency. The emerging ferroelectric nematic liquid crystals have attracted widespread interest in soft matter due to their unique combination of ferroelectricity and fluidity. However, the birefringence, which is one of the most important optical parameters in electro-optic devices, is not large enough (<0.

Equity of intensive care unit bed resource allocation in ethnic minority areas of China-an empirical analysis based on geographical and population dimensions.

Objective: The purpose of this study is to analyse the changes in the equity of intensive care unit (ICU) bed allocation in 14 cities in China's Guangxi Zhuang Autonomous Region from 2018 to 2021, to identify the problems in the process of ICU bed allocation in China's ethnic minority regions.

Design: The Gini coefficient, Theil index, health resource density index, and spatial correlation analysis were used to analyse the current status of ICU bed resource allocation and allocation equity in Guangxi, China, on two dimensions: geography, and population.

Setting: The Guangxi Zhuang Autonomous Region.
