The association of gene polymorphisms in SREBP and its interaction with nutritional status on blood pressure phenotypes among children: a cross-sectional study.

Introduction: Previous studies have confirmed that the SREBP polymorphisms are associated with dyslipidemia. However, no researchers investigated the association between SREBP polymorphisms and blood pressure phenotypes in children.

Methods: A convenient cluster sampling method was adopted to conduct field survey in three middle schools.

Evaluating ECAMM-based training efficacy for malaria microscopists in Hunan Province, China.

Background: The rapid and accurate diagnosis of malaria has contributed to China's remarkable achievement in malaria elimination. In the post-elimination phase, microscopic examination remains crucial for preventing the reintroduction of imported malaria. This study developed and validated a 4-day external competency assessment training program for malaria microscopists based on the External Competency Assessment for Malaria Microscopists (ECAMM) framework, to enhance diagnostic proficiency among laboratory personnel in public health institutions.

Interpretable machine learning models for predicting childhood myopia from school-based screening data.

This study assessed the efficacy of various diagnostic indicators and machine learning (ML) models in predicting childhood myopia. A total of 2,365 children aged 5-12 years were included in the study. The participants were exposed to non-cycloplegic and cycloplegic refraction tests, along with ocular biometric assessments.

Avian influenza A(H5N6) virus detected during live-poultry market surveillance linked to a human infection in Changsha, China, from 2020 to 2023.

In November 2022, we reported a fatal case of human infection caused by a highly pathogenic avian influenza A(H5N6) virus bearing a clade 2.3.4.

Knowledge, practice, and information sources regarding infectious diseases among Chinese children and adolescents: a National-Level cross-sectional study.

Objective: To investigate the characteristics and interrelationships between knowledge, preventive practice, and information sources of infectious diseases among Chinese children.

Methods: This study used data collected from the baseline survey of a China national multi-centered cluster-randomized controlled trial in 2013. A total of 30,287 children completed a questionnaire package that included measures for knowledge, preventive practice and information sources related to infectious diseases.

Effectiveness of an Internet-Based Acceptance and Commitment Therapy Intervention for Reducing Psychological Distress in Health Care Professionals: Randomized Controlled Trial.

Background: Psychological distress is prevalent among health care professionals and can lead to poor-quality patient care. Internet-based acceptance and commitment therapy (iACT) is a promising intervention for improving mental health due to its low cost and easy access. However, there is limited evidence of its effectiveness in reducing health care professionals' psychological distress.

An overview of avian influenza surveillance strategies and modes.

The global epidemic of avian influenza has imposed a substantial disease burden, inciting substantial societal panic and economic losses. The high variability and associated uncertainty of the influenza virus present significant challenges in its prevention and control. As a pivotal strategy for the mitigation of avian influenza, the surveillance network has shown considerable growth at both global and regional levels.

Development and Validation of Knowledge Assessment Scales for Dementia and Urinary Incontinence in Community Older People.

To develop and validate scales for reliably assessing dementia and urinary incontinence knowledge of older adults in the community. Items were generated through a literature review, refined through a Delphi study ( = 19), and then revised through a pilot study ( = 29). Item analysis and exploratory factor analysis were applied to finalize the scales ( = 244).

Development and validation of frailty and malnutrition knowledge assessment scale for community-dwelling older adults.

There is a lack of reliable tools to assess the knowledge of frailty and malnutrition in community-dwelling older adults. To develop and validate reliable frailty and malnutrition knowledge assessment scales for this population, two scales were developed and validated through five phases. Phase 1: the item pools were constructed through a literature review and research panel based on the symptom interpretation model.

Development and validation of knowledge assessment scales on sarcopenia and fall for Chinese community-dwelling older adults.

Aim: This study aimed to develop and validate sarcopenia and fall knowledge assessment scales for community-dwelling older adults.

Methods: A five-phase, systematic and standardized process was used. Phase 1: item pools were constructed based on the Symptom Interpretation Model.

Human infection of avian influenza A H3N8 virus and the viral origins: a descriptive study.

Background: The H3N8 avian influenza virus (AIV) has been circulating in wild birds, with occasional interspecies transmission to mammals. The first human infection of H3N8 subtype occurred in Henan Province, China, in April, 2022. We aimed to investigate clinical, epidemiological, and virological data related to a second case identified soon afterwards in Hunan Province, China.

[Association between low blood lead exposure and nervous system symptoms].

Objective: To explore the association between low blood lead exposure and nervous system symptoms among the workers exposed to oil paint.

Methods: Through cluster sampling, workers with occupational oil paint exposure in 2 factories were selected to conduct a questionnaire survey, biochemical detection and health examination. χ2 test and unconditional logistic regression analysis were performed for the determinants analysis.

Influence of extreme weather and meteorological anomalies on outbreaks of influenza A (H1N1).

Biological experiments and epidemiological evidence indicate that variations in environment have important effect on the occurrence and transmission of epidemic influenza. It is therefore important to understand the characteristic patterns of transmission for prevention of disease and reduction of disease burden. Based on case records, we analyzed the environmental characteristics including climate variables in Changsha, and then constructed a meteorological anomaly susceptive-infective-removal (SIR) model on the basis of the results of influenza A (H1N1) transmission.

[Survey on historical Oncomelania snail environments in Changshu City].

The historical Oncomelania snail environments discovered since 1976 were surveyed in Changshu City, Jiangsu Province. There were 425 foci of historical snail environments that were discovered in 16 towns, the snail area was 124 893 m2. The transformation rates of historical snail environments and of the snail area were 76.

[Risk related to the transmission of H5N1 subtype avian influenza virus in the environment of poultry markets in Changsha, China].

Objective: To investigate the risk of H5N1 subtype avian influenza virus (AIV) transmission in the poultry market environment in Changsha city. H5N1 antibody levels among the groups related occupational exposure and AIV nucleic acid in the environment of poultry markets were detected. The characteristics of haemagglutinin (HA) genes of H5N1 AIV in the environment were analyzed.

[Investigation of health status of workers exposed to low concentration cadmium in a zinc powder factory].
