The death of neighborhood food outlets
The global transformation of the retail environment has led to the widespread closure of small food outlets, threatening urban sustainability and dietary health. While extensive studies have explored the relationship between urban environments and food outlet closures, most of them do not differentiate between the closures of healthy and unhealthy food outlets. To address this gap, this study employs interpretable machine learning methods to exam…
Red Cell Distribution Width as a Predictive Biomarker for Early Lung Injury in Pediatric Patients Following Cardiopulmonary Bypass
Background: Red cell distribution width (RDW) has emerged as a prognostic biomarker in various clinical contexts. This retrospective study evaluated the predictive utility of RDW for cardiopulmonary bypass-associated acute lung injury (CPB-ALI) in pediatric patients undergoing cardiac surgery. Methods: A total of 166 children were enrolled and classified into CPB-ALI and non-ALI groups. Preoperative and postoperative RDW values were analyzed. Res…
Genetic Pleiotropy and Causal Pathways Linking Glycemic Traits to Asthma
Background: While diabetes is a recognized risk factor for asthma, the shared genetic components between diabetes/glycemic traits and asthma remain unclear. This study investigates the genetic associations, causal relationships, and underlying mechanisms linking these conditions. Methods: We assessed global genetic correlations using linkage disequilibrium score regression (LDSC), high-definition likelihood analysis (HDL), and genetic covariance …

Background Protecting and improving the personal health of healthcare workers is critical to improving the efficiency and quality of care. To effectively meet the needs of the emergency service system, emergency physicians need to be in a good state of health. However, due to the special characteristics of work in the emergency department, emergency physicians have to face various psychosocial pressures, which may bring them physical and mental d…
Effect of esketamine on postoperative depressive symptoms in patients undergoing thoracoscopic lung cancer surgery
Perioperative administration of esketamine reduced the incidence of depressive symptoms at 1 month after thoracoscopic lung cancer surgery. History of hypertension and preoperative anxious symptoms were independent risk factors for depressive symptoms. Clinical trial registration: Chinese Clinical Trial Registry http://www.chictr.org.cn, Identifier (ChiCTR2100046194)
Organizational commitment of emergency physician and its related factors
Background: Organizational commitment is important for job performance and employee retention. However, studies on the level of organizational commitment and its related factors among emergency physicians in China are scarce. Therefore, this study aimed to identify the factors associated with organizational commitment among emergency physicians in China. Methods: A national cross-sectional study was conducted in 2018 among emergency physicians in…
Trends of Hypercholesterolemia Change in Shenzhen, China During 1997–2018
To demonstrate the trends of hypercholesterolemia change in Shenzhen, China from 1997 to 2018. Participants were residents aged 18 to 69 years in Shenzhen, China, and were recruited using multi-stage cluster sampling. All participants were surveyed about their socio-demographics, lifestyle, occupation, mental health, and social support. Physical measurements and blood samples for subsequent measurements were collected according to a standardized …
International competitiveness and currency internationalization
This paper aims to explore the relation between international competitiveness and currency internationalization by employing an analytical framework and applying it to RMB internationalization. Our results reaffirm that economic size, financial market development and network externalities are keys in currency internationalization. We also find that international competitiveness is a potential determinant of currency internationalization. However,…

Acute Stress Disorder Among Frontline Health Professionals During the Covid-19 Outbreak
OBJECTIVE: The outbreak of COVID-19 that commenced in December 2019 in Wuhan, China, has caused extensive public health concerns and posed substantial challenges to health professionals, especially for those in the center of the epidemic. The current study aimed to assess the prevalence, related factors, and mechanism of acute stress disorder (ASD) among health professionals in Wuhan during this critical period. METHODS: The study used a cross-se…
Occupational Burnout Among Frontline Health Professionals in a High-Risk Area During the Covid-19 Outbreak
Background: The outbreak of coronavirus disease 2019 (COVID-19) resulted in a substantial workload and stress for frontline health professionals in high-risk areas. Little research has investigated the mechanism of occupational burnout among the frontline health professionals located in the center of the epidemic in Wuhan, China. Methods: A total of 199 frontline health professionals from Wuhan Jinyintan Hospital completed the cross-sectional sur…
Modelling Analysis of Covid-19 Transmission and the State of Emergency in Japan
To assess the effectiveness of the containment strategies proposed in Japan, an SEIAQR (susceptible-exposed-infected-asymptomatic-quarantined-recovered) model was established to simulate the transmission of COVID-19. We divided the spread of COVID-19 in Japan into different stages based on policies. The effective reproduction number Re and the transmission parameters were determined to evaluate the measures conducted by the Japanese Government du…

Interpersonal Trauma and Risk of Depression Among Adolescents
Interpersonal trauma in adolescent is an important public health concern. Depression can be a main consequence of interpersonal trauma, which subsequently results in various negative mental health outcomes. Previous research has investigated the independent effects of interpersonal trauma, interpersonal relationships and physical exercise on the risk of depression. However, the interaction effect of the three factors on depression remains unclear…
Physical Activity-Related Injuries and Risk Factors among Secondary School Students in Hong Kong
Increase in physical activity (PA) might elevate risks for physical-activity-related injuries (PARIs). This study aimed to investigate the incidence rate and risk factors for PARIs among secondary school students in Hong Kong. All eligible students from three secondary schools were invited to participate in the study from November to December 2014. Information on PARI occurrences in the past 12 months, PA participation, and sociodemographics was …
Association between Neighborhood Food Access, Household Income, and Purchase of Snacks and Beverages in the United States
Considerable research on the risk factors of obesity and chronic diseases has focused on relationships between where people live, where they shop, and the types of food they purchase. Rarely have investigators used a national sample and explicitly addressed the amount of energy-dense and nutrient-poor foods purchased in different types of neighborhood food stores. Even more rarely have studies accounted for the characteristics of the broader buil…
