Associations Between Change in Kidney Functioning, Age, Race/Ethnicity, and Health Indicators in the Health and Retirement Study.

Background: The aging process is accompanied by decline in kidney functioning. It remains unknown to what extent age-related decline in kidney functioning can be attributed to health indicators, and whether rate of decline differs across sociodemographic groups.

Methods: Using data from the Health and Retirement Study from 2006/2008 through 2014/2016, we estimated kidney functioning trajectories, determined by cystatin C, among adults aged over 51 over 8 years.

Changes in social lives and loneliness during COVID-19 among older adults: a closer look at the sociodemographic differences.

Objectives: The COVID-19 pandemic greatly impacted the social lives of older adults across several areas, leading to concern about an increase in loneliness. This study examines the associations of structural, functional, and quality aspects of social connection with increased loneliness during COVID-19 and how these associations vary by sociodemographic factors.

Design: Secondary data analyses on a nationally representative survey of older US adults.

Mortality and morbidity in ageing men: Biology, Lifestyle and Environment.

Males live shorter lives than women in all countries. The universality of shorter male life expectancy is a 21st Century phenomena. It occurs with the decline in infectious diseases and the rise in cardiovascular diseases accounting for mortality.

Media trust and infection mitigating behaviours during the COVID-19 pandemic in the USA.

Introduction: The COVID-19 pandemic is an unprecedented public health crisis. It is becoming increasingly clear that people's behavioural responses in the USA during this fast-changing pandemic are associated with their preferred media sources. The polarisation of US media has been reflected in politically motivated messaging around the coronavirus by some media outlets, such as Fox News.

High-efficiency near-infrared enabled planar perovskite solar cells by embedding upconversion nanocrystals.

Integration of the upconversion effect in perovskite solar cells (PSCs) is a facile approach towards extending the spectral absorption from the visible to the near infrared (NIR) range and reducing the non-absorption loss of solar photons. However, the big challenge for practical application of UCNCs in planar PSCs is the poor compatibility between UCNCs and the perovskite precursor. Herein, we have subtly overcome the tough compatibility issue using a ligand-exchange strategy.
