Exploring diagnostic stewardship in the emergency department evaluation of pediatric abdominal pain in a statewide quality collaborative.

Background: Diagnostic stewardship is the effort to optimize diagnostic testing to reduce errors while avoiding overtesting and overtreatment. Abdominal pain and appendicitis in children are essential use cases. Delayed diagnosis of appendicitis can be dangerous and even life-threatening, but overtesting is harmful.

[Structural equation analysis and modeling of wrist WMSDs and its adverse ergonomic factors].

To investigate the relationships and impacts between various occupational ergonomic hazards and hand and wrist fatigue, as well as work-related musculoskeletal disorders (WMSDs) of the hand and wrist, and to propose targeted preventive and intervention measures for adverse occupational ergonomic factors causing WMSDs of the hand and wrist. From 2018 to December 2023, a nationwide epidemiologic survey study of wrist WMSDs was conducted using the Chinese version of the electronic questionnaire system for musculoskeletal disorders.A total of 88, 609 valid questionnaires were collected.

[Study on the epidemiological characteristics of work-related musculoskeletal disorders among 29 industries or occupational groups in China].

To analyze the distribution characteristics of work-related musculoskeletal disorders (WMSDs) among the occupational population in China's key industries during the period from 2018 to 2023, and to provide data support for the formulation of targeted prevention strategies. Between January 1, 2018, and December 31, 2023, a cross-sectional epidemiological survey and a retrospective investigation were conducted in seven geographical regions of North China, East China, Central China, South China, Southwest China, Northwest China, and Northeast China, using a combination of epidemiological cross-sectional and retrospective surveys. The industries were stratified according to the degree of closeness to WMSDs, the size of the occupational population, and the importance of the national economy, and then cluster sampling was conducted according to the size of the enterprises (large, medium, and small) within each stratum.

Molecular identification of tick (Acari: Ixodidae) and tick-borne pathogens from Przewalski's gazelle (Procapra Przewalskii) and Tibetan sheep (Ovis aries) in Qinghai Lake National Nature Reserve, China.

The Qinghai Lake National Nature Reserve (QLNNR), renowned for its abundant natural resources and diverse ecological habitats, serves as an ideal environment for ticks, thereby increasing the risk of various tick-borne pathogens (TBPs) transmission. This study aimed to investigate the prevalence of TBPs in ticks collected from Przewalski's gazelle and Tibetan sheep within the QLNNR. A total of 313 tick samples were collected from the vicinity of Qinghai Lake.

Ligand-Mediated Surface Reaction for Achieving Pure 2D Phase Passivation in High-Efficiency Perovskite Solar Cells.

The surface passivation with the heterostructure of the 2D/3D stack has been widely used for boosting the efficiency of n-i-p perovskite solar cells (PSCs). However, the disordered quantum well width distribution of 2D perovskites leads to energy landscape inhomogeneity and crystalline instability, which limits the further development of n-i-p PSCs. Here, a versatile approach, ligand-mediated surface passivation, was developed to produce a phase-pure 2D perovskite passivation layer with a homogeneous energy landscape by dual-ligand codeposition.

Analysis of urban-rural differences in the relationship between grandparenting and the nutrition and health status of children aged 0-3 in China.

Background: The practice of grandparents taking on the role of primary caregivers for their grandchildren is widespread across both urban and rural regions in China. Yet, the existing body of research offered limited clarity on how grandparenting associated with nutrition as well as health of children aged 0-3 years, particularly in terms of potential differences between urban and rural areas in China. Therefore, this study aims to delve into the association between grandparenting and nutrition as well as health status of children aged 0-3 and its urban-rural differences in China.

The quantity, reliability, transparency, reporting, and interpretation of pharmacovigilance signal detection studies in pregnancy: a meta-epidemiological study.

Purpose: To systematically review the characteristics of the available pharmacovigilance signal detection studies in pregnancy, and comprehensively assess the reliability, transparency, reporting, and interpretation of these studies.

Methods: We searched five databases from inception to February 2024 to identify the available pharmacovigilance signal detection studies in pregnancy. We extracted three aspects of information (basic information, data processing modes, signal detection analyses) to assess the reliability, transparency, and reporting of each study.

Alternative antibiotic selections during the 2022 amoxicillin shortage in the US.

This study of seven pediatric hospitals identified that the amoxicillin shortage in 2022 resulted in a decline in amoxicillin suspension prescribing by 30.8% with increases in use of amoxicillin non-suspension (+7.9) and broad-spectrum antibiotics.

Depression in childhood to early adulthood and respiratory health in early adulthood.

Background: Both depression and respiratory disease are common today in young populations. However, little is known about the relationship between them.

Aims: This study aims to explore the association between depression in childhood to early adulthood and respiratory health outcomes in early adulthood, and the potential underlying mechanisms.

Navigating ethical and legal challenges in the HEALthy Brain and Child Development Study: Lessons learned from the ethics, law, policy working group.

The HEALthy Brain and Child Development (HBCD) Study, a multi-site prospective longitudinal cohort study, will examine human brain, cognitive, behavioral, social, and emotional development beginning prenatally and planned through early childhood. The HBCD study has faced several ethical and legal challenges due to its goal of enrolling pregnant people (including those with substance use disorder) and their newborns. Challenges not fully anticipated at the outset emerged from the rapidly changing legal landscape around reproductive rights in the United States.

How Child Health Financing and Payment Mitigate and Perpetuate Structural Racism.

Health financing for children and youth comes mainly from commercial sources (especially, a parent's employer-sponsored insurance) and public sources (especially, Medicaid and Children's Health Insurance Plan [CHIP]). These 2 sources serve populations that differ in race and ethnicity. This inherent segregation perpetuates a system of disparities in health and health care.

Evaluating a National Biomedical Training Program Using QuantCrit: Revealing Disparities in Research Self-efficacy for Women of Color Undergraduates.

Program evaluation for interventions aimed at enhancing diversity can fall short when the evaluation unintentionally reifies the exclusion of multiple marginalized student experiences. The present study presents a Quantitative Critical Race Theory (QuantCrit) approach to program evaluation to understand outcomes for Women of Color undergraduates involved in a national biomedical training program called the Building Infrastructure Leading to Diversity (BUILD) initiative. Using longitudinal data, we examined the impact of participation in the BUILD Scholars programs and BUILD-developed novel biomedical curriculum on undergraduate's research self-efficacy.
