A network comparison analysis of socio-ecological protective and risk factors of depression between Chinese urban and rural adolescents.

Background: Anchoring in the socio-ecological framework and the differential impact theory, the present study pioneered to explore the differential network structures of multilevel risk and protective factors that influence depression among Chinese urban and rural adolescents.

Method: A sample of 684 urban adolescents and 1123 rural adolescents completed a battery of self-report questionnaires measuring their depressive symptoms, as well as risk and protective factors at intrapersonal (psychological flexibility, emotion regulation), interpersonal (social support, parental control), and social levels (social capital, stressful life events).

Results: Central risk and protective factors in both groups included psychological flexibility, which bridged intrapersonal, interpersonal and social resources, along with social support, social capital, rumination, catastrophizing, and self-blame.

Extreme temperature increases the risk of COPD morbimortality: A systematic review and meta-analysis.

Introduction: This systematic review examines how extreme temperatures impact chronic obstructive pulmonary disease (COPD) morbidity and mortality, focusing on identifying vulnerable subpopulations.

Methods: We conducted a systematic literature search from January 1, 2000, to November 6, 2024, across databases like PubMed, MEDLINE and EMBASE, Web of Science, and Scopus, focusing on observational studies that quantitatively defined extreme temperatures and their impacts on COPD morbidity and mortality. Out of 3140 records, 25 studies met the inclusion criteria.

Knowledge, perception, and behaviours related to antibiotic use and antimicrobial resistance in community-dwelling individuals in Hong Kong.

Background: Understanding public knowledge and behaviours related to antibiotics and antimicrobial resistance (AMR) may inform interventions to reduce inappropriate antibiotics use.

Methods: We conducted a questionnaire survey in community-dwelling adults in Hong Kong from 2020 to 2022 to examine knowledge, risk perception on AMR and antibiotics, and behavioural patterns in antibiotic use. Information on demographics, socioeconomic status and general health was examined in relation to the knowledge score, antibiotic use behaviours and preference for antibiotic-free food products in regression models.

Independent Association of Individual Lipid Abnormalities with Cardiovascular All-cause Mortality: A Prospective Cohort Study.

Introduction: Abnormalities in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) are each associated with increased cardiovascular risk, after adjusting for non-lipid risk factors. However, whether and to what extent the association for each lipid measure is confounded by other lipid measures is less understood.

Aim: This study aims to investigate the association of each lipid measure with cardiovascular and all-cause mortality while precluding the confounding caused by abnormalities in other lipid measures.

International consensus statement on microbiome testing in clinical practice.

There is growing interest in the potential exploitation of the gut microbiome as a diagnostic tool in medicine, but evidence supporting its clinical usefulness is scarce. An increasing number of commercial providers offer direct-to-consumer microbiome diagnostic tests without any consensus on their regulation or any proven value in clinical practice, which could result in considerable waste of individual and health-care resources and potential drawbacks in the clinical management of patients. We convened an international multidisciplinary expert panel to standardise best practices of microbiome testing for clinical implementation, including recommendations on general principles and minimum requirements for their provision, indications, pre-testing protocols, method of analyses, reporting of results, and potential clinical value.

New mechanisms of PM induced atherosclerosis: Source dependent toxicity and pathogenesis.

Exposure to fine particulate matter (PM) is recognized to induce atherosclerosis, but the underlying mechanisms are not fully understood. This study used ambient PM samples collected in one of the highly polluted regions of Guanzhong Plain in China (2017-2020) and an ApoE mouse model to investigate the association between exposure to PM and atherosclerosis. Despite a substantial decrease in the ambient concentration of PM from 266.

Differential antigenic imprinting effects between influenza H1N1 hemagglutinin and neuraminidase in a mouse model.

Unlabelled: Understanding how immune history influences influenza immunity is essential for developing effective vaccines and therapeutic strategies. This study examines the antigenic imprinting of influenza hemagglutinin (HA) and neuraminidase (NA) using a mouse model with sequential infections by H1N1 virus strains exhibiting substantial antigenic differences in HA. In our pre-2009 influenza infection model, we observed that mice with more extensive infection histories produced higher levels of functional NA-inhibiting antibodies (NAI).

Effect of aspirin on biomarker profile in women at high risk for preeclampsia.

Background: There is limited evidence in the literature regarding the temporal changes of preeclampsia-related biomarkers during pregnancy in high-risk women who develop preeclampsia despite the administration of aspirin prophylaxis.

Objective: This study aimed to compare the temporal changes in mean arterial pressure, uterine artery pulsatility index, placental growth factor, and soluble fms-like tyrosine kinase-1 across gestation in women identified as having high risk for preterm preeclampsia receiving aspirin prophylaxis and low-risk women without aspirin treatment.

Study Design: This was a prospective longitudinal nested case-control study of 2007 women with singleton pregnancies who participated in the first-trimester screen-and-prevent program for preeclampsia at the Prince of Wales Hospital, Hong Kong Special Administrative Region, China, between January 2020 and May 2023.

Methods: In total, 1313 Canadian infants from the CHILD Cohort Study were involved in this study.

Reconstructed influenza A/H3N2 infection histories reveal variation in incidence and antibody dynamics over the life course.

Humans experience many influenza infections over their lives, resulting in complex and varied immunological histories. Although experimental and quantitative analyses have improved our understanding of the immunological processes defining an individual's antibody repertoire, how these within-host processes are linked to population-level influenza epidemiology in humans remains unclear. Here, we used a multilevel mathematical model to jointly infer antibody dynamics and individual-level lifetime influenza A/H3N2 infection histories for 1,130 individuals in Guangzhou, China, using 67,683 haemagglutination inhibition (HI) assay measurements against 20 A/H3N2 strains from repeat serum samples collected between 2009 and 2015.

Triglyceride-glucose index (TyG index) is associated with a higher risk of colorectal adenoma and multiple adenomas in asymptomatic subjects.

Hypothesis: The objective of this study is to evaluate the predictive ability of the TyG index for the presence of adenoma and multiple adenomas in an asymptomatic population.

Design: A secondary analysis was conducted on a prospective cohort of asymptomatic subjects aged between 50 and 75 who underwent CRC screening. Fasting blood glucose (FBG) and lipid profiles were measured within three months prior colonoscopy.

Short-chain fatty acids in viral infection: the underlying mechanisms, opportunities, and challenges.

Viral infections can cause cellular pathway derangements, cell death, and immunopathological responses, leading to host inflammation. Short-chain fatty acids (SCFAs), produced by the microbiota, have emerged as a potential therapeutic for viral infections due to their ability to modulate these processes. However, SCFAs have been reported to have both beneficial and detrimental effects, necessitating a comprehensive understanding of the underlying mechanisms.

Linking joint exposures to residential greenness and air pollution with adults' social health in dense Hong Kong.

Despite the growing recognition of the impact of urban environments on social health, limited research explores the combined associations of multiple urban exposures, particularly in dense cities. This study examines the interplay between greenspace, air pollution, and social health as well as the underlying pathways and population heterogeneity in Hong Kong using cross-sectional survey data from 1977 adults and residential environmental data. Social health includes social contacts, relations, and support.

Job characteristics, personal characteristics and well-being of nursing assistants in long-term care facilities: A mixed methods systematic review and narrative synthesis.

Background: Within long-term care facilities, paraprofessional nursing assistants account for the largest proportion of the health care workforce and provide essential direct care to older people with complex care needs. There is a gap in developing a theory-driven, systematic synthesis of the job characteristics and well-being outcomes specific to this occupational group, as most existing studies evaluate either professional health care workers or both professional and nursing assistants.

Aim: Develop an occupation-specific conceptual model on the job characteristics and well-being of nursing assistants in long-term care facilities drawing upon the job demands-resources model.

Suitable temperature indicator for adverse health impacts in sub-tropical cities: a case study in Hong Kong from 2010-2019.

Heat-health warning systems and services are important preventive actions for extreme heat, however, global evidence differs on which temperature indicator is more informative for heat-health outcomes. We comprehensively assessed temperature predictors on their summer associations with adverse health impacts in a high-density subtropical city. Maximum, mean, and minimum temperatures were examined on their associations with non-cancer mortality and hospital admissions in Hong Kong during summer seasons 2010-2019 using Generalized Additive Models and Distributed Lag Non-linear Models.
