Innate Immune Activation and Mitochondrial ROS Invoke Persistent Cardiac Conduction System Dysfunction after COVID-19.

Background: Cardiac risk rises during acute SARS-CoV-2 infection and in long COVID syndrome in humans, but the mechanisms behind COVID-19-linked arrhythmias are unknown. This study explores the acute and long term effects of SARS-CoV-2 on the cardiac conduction system (CCS) in a hamster model of COVID-19.

Methods: Radiotelemetry in conscious animals was used to non-invasively record electrocardiograms and subpleural pressures after intranasal SARS-CoV-2 infection.

Community support, social isolation and older adults' life satisfaction: evidence from a national survey in China.

Objectives: Despite the recognized importance of community social service and community built facility for enhancing older adults' life satisfaction, the mechanisms underlying their relationship have not been thoroughly examined. This study aims to complement the existing knowledge by investigating the mediating role of social disconnectedness and loneliness in the association between community support and life satisfaction among older adults.

Methods: Using data from the 2018 China Longitudinal Aging Social Survey, the study analyzes responses from 9,874 Chinese older adults (mean age = 71.

Patterns of Social Determinants of Health and Child Mental Health, Cognition, and Physical Health.

Importance: Social determinants of health (SDOH) influence child health. However, most previous studies have used individual, small-set, or cherry-picked SDOH variables without examining unbiased computed SDOH patterns from high-dimensional SDOH factors to investigate associations with child mental health, cognition, and physical health.

Objective: To identify SDOH patterns and estimate their associations with children's mental, cognitive, and physical developmental outcomes.

COVID-19 Policies, Pandemic Disruptions, and Changes in Child Mental Health and Sleep in the United States.

Importance: The adverse effects of COVID-19 containment policies disrupting child mental health and sleep have been debated. However, few current estimates correct biases of these potential effects.

Objectives: To determine whether financial and school disruptions related to COVID-19 containment policies and unemployment rates were separately associated with perceived stress, sadness, positive affect, COVID-19-related worry, and sleep.

Psychological Well-Being of Left-Behind Children in China: Text Mining of the Social Media Website Zhihu.

China's migrant population has significantly contributed to its economic growth; however, the impact on the well-being of left-behind children (LBC) has become a serious public health problem. Text mining is an effective tool for identifying people's mental state, and is therefore beneficial in exploring the psychological mindset of LBC. Traditional data collection methods, which use questionnaires and standardized scales, are limited by their sample sizes.

Examining cultural competence in health care: implications for social workers.

This article examines and unpacks the "black box" of cultural competence in health interventions with racial and ethnic minority populations. The analysis builds on several recent reviews of evidence-based efforts to reduce health disparities, with a focus on how cultural competence is defined and operationalized. It finds that the use of multiple similar and indistinct terms related to cultural competence, as well as the lack of a mutually agreeable definition for cultural competence itself, has resulted in an imprecise concept that is often invoked but rarely defined and only marginally empirically validated as an effective health intervention.

Social service utilization, sense of community, family functioning and the mental health of new immigrant women in Hong Kong.

Drawing upon a sample of 296 new immigrant women in Hong Kong, this study investigated how social service utilization, family functioning, and sense of community influenced the depressive symptoms of new immigrant women. Results of the structural equation modeling suggested that family functioning and sense of community were both significantly and negatively associated with the depression of new immigrant women. Utilization of community services also influenced the depression of immigrant women indirectly through the mediating effect of sense of community.

Sense of community, neighboring, and social capital as predictors of local political participation in China.

This study examines the state of sense of community, neighboring behavior, and social capital in the People's Republic of China, and explores their ability to predict local political participation, in the form of voting in elections for Urban Resident/Rural Villager Committees. Using a nationally representative survey, rural, older and married residents and those with a primary or high school education and higher perceived socio-economic status are more likely to participate. In rural areas, men are more likely than women to vote.

Racial and ethnic variations in caregiver service use.

Objective: This article examines whether race and ethnicity contribute to the differential use of caregiver support services, when controlling for caregiver and care recipient characteristics, as represented by predisposing, enabling, and need factors included in the Behavioral Model of Health Services Use.

Methods: The study includes 1,508 individuals who provide care to an ill or disabled adult aged 50 or older, identified through a random digit dial telephone survey of California households. Logistic regression analysis is utilized to examine factors that predict use of caregiver support services.

The status of low-income neighborhoods in the post-welfare reform environment: mapping the relationship between poverty and place.

It has long been recognized that children and adults living in poverty are at risk for a number of negative outcomes. As inequality in the distribution of wealth, income and opportunity has grown in the U.S.

Racial/ethnic disparities in the use of mental health services in poverty areas.

Objectives: This study examined racial/ethnic disparities in mental health service access and use at different poverty levels.

Methods: We compared demographic and clinical characteristics and service use patterns of Whites, Blacks, Hispanics, and Asians living in low-poverty and high-poverty areas. Logistic regression models were used to assess service use patterns of minority racial/ethnic groups compared with Whites in different poverty areas.
