Evaluation of muscle mass relative to weight/sitting height improves the association with physical performance.

Objectives: To compare relationships of appendicular skeletal muscle mass (ASM) with the function of the upper and lower extremities, after the former has been adjusted by five body size variables: height; weight; body mass index (BMI); sitting height; and weight/sitting height.

Study Design: A cross-sectional study of data derived from the baseline phase of the Physical Activity and Health in Older Women Study.

Main Outcome Measures: ASM was measured by bioelectrical impedance analysis.

Chewing difficulty and frailty trajectories in Chinese nursing home residents: A prospective cohort study.

Aim: To investigate frailty trajectories in nursing home residents, and to test whether chewing difficulty was a significant factor associated with frailty trajectories.

Methods: This is a 1-year prospective cohort study. Data were collected from 27 nursing home residents in China at baseline, 6 months, and 12 months.

N-methyladenosine reader YTHDF1 regulates the proliferation and migration of airway smooth muscle cells through mA/cyclin D1 in asthma.

Asthma is a chronic inflammatory respiratory disease, which is involved in multiple pathologic molecular mechanisms and presents a huge challenge to clinic nursing. Emerging evidence suggests that N-methyladenosine (mA) plays critical roles in respiratory system disease. Thus, present work tried to investigate the functions of mA reader YTHDF 1 in asthma.
