Seroepidemiology of pertussis in Huzhou: A population-based, cross-sectional study.

Purpose: The resurgence of pertussis has occurred around the world. However, the epidemiological profiles of pertussis cannot be well understood by current diseases surveillance. This study was designed to understand the seroepidemiological characteristics of pertussis infection in the general population of Huzhou City, evaluate the prevalence infection of pertussis in the population, and offer insights to inform adjustments in pertussis prevention and control strategies.

Analysis of data from two influenza surveillance hospitals in Zhejiang province, China, for the period 2018-2022.

Purpose: To assess the epidemiology of seasonal influenza in Huzhou City, Zhejiang Province, China, during 2018-2022 and provide insights for influenza prevention.

Methods: Following the National Influenza Surveillance Program, we conducted pathogen surveillance by randomly sampling throat swabs from cases with influenza-like illness (ILI) at two sentinel hospitals.

Results: From 2018 to 2022, a total of 3,813,471 cases were treated at two hospitals in Huzhou, China.

Educational Mismatch and Workers' Fertility Intentions: Evidence from China.

This paper focuses on the impact of the educational mismatch on workers' fertility intentions and explores the underlying mechanisms. Empirical research based on the China Family Panel Survey (CFPS) data shows that undereducation has a negative effect on the fertility intentions of women aged 18-35, whereas overeducation reports no effect, a finding that remains stable in the robustness test and the IV model. An explanation for this phenomenon is that undereducated female workers have a wage premium and higher expectations of career development, which implies a greater opportunity cost of fertility.

Association between body image dissatisfaction and body anthropometric indices among Chinese children and adolescents at different developmental stages.

Objective: Children at different developmental stages show different physical development and psychological cognitive characteristics and may pay different attention to body parts. The purpose of this study was to analyze the associations between body image dissatisfaction (BID) and body anthropometric indices (BAIs) among Chinese children and adolescents at different developmental stages.

Methods: A total of 609 Chinese primary and secondary school students aged 8-15 years (329 boys and 280 girls) were selected using stratified cluster sampling.

Relative children's lipid accumulation with hypertension in Chinese children and adolescents.

Background: This study aimed to develop a novel indicator associated with hypertension in Chinese children and adolescents, the relative children's lipid accumulation product (RCLAP).

Methods: A cross-sectional study was conducted in 2018. A total of 683 students aged 8-15 years were recruited via a stratified cluster sampling Methods.

Optimal cutoff of the abdominal skinfold thickness (AST) to predict hypertension among Chinese children and adolescents.

Previous studies have shown that the correlation between the abdominal skinfold thickness (AST) and hypertension is better than that observed using the body mass index (BMI) or waist-to-height ratio (WHtR). We aimed to explore the optimal cutoff of the AST to predict childhood hypertension. The AST percentiles were calculated based on 215,223 students from the Chinese National Survey on Students' Constitution and Health (CNSSCH) in 2010 using the LMS method.

Relative Children's Lipid Accumulation Product Is a Novel Indicator for Metabolic Syndrome.

Background: The children's lipid accumulation product (CLAP) is associated with MS in Chinese children and adolescents. The aim of this study was to develop a more effective indicator, the relative children's lipid accumulation product (RCLAP) was evaluated for correlation with MS and the density of lipid accumulation.

Methods: A stratified cluster sampling method was used to recruit 683 students aged 8-15 years in this study.

Emerging porous materials in confined spaces: from chromatographic applications to flow chemistry.

Searching for porous materials that can be employed as solid stationary phases for chromatographic separations, porous membrane matrixes and solid supports for catalysis has become an active research area. Strategies for embedding emerging porous materials in columnar systems and their subsequent applications (separation and catalysis) have been developed, which benefit from the remarkable progress in the discovery and development of porous materials based on metal-organic coordination or dynamic covalent bonding such as metal-organic frameworks (MOFs), covalent-organic frameworks (COFs), porous organic cages, and porous organic polymers. In this review, porous materials that have been confined within capillary columns as packed, monolithic and open tubular columns are discussed.

Effect of cellulose nanocrystals on the crystallization behavior and enzymatic degradation of poly(butylene adipate).

Cellulose nanocrystals (CNCs) are nature-resourced nanoparticles and have been widely used to improve performance of biodegradable polyesters. Two types of CNCs respectively prepared by sulphuric acid hydrolysis (aCNCs) and ammonium persulfate oxidation (oCNCs) processes were incorporated into poly(butylene adipate) (PBA) matrix to regulate its crystallization behavior and enzymatic degradation performance. Thermal and X-ray diffraction analysis revealed that both aCNCs and oCNCs could promote the crystallization ability and lamellar thickening of α-form PBA, while oCNCs showed stronger promotion than aCNCs.
