Aims: To determine prevalence, causes, and risk factors of reduced uncorrected visual acuity (UCVA), reduced presenting visual acuity (PVA), and persistent reduced visual acuity (VA) among Chinese preschool children.

Methods: The longitudinal, population-based Nanjing Eye Study (NES) was carried out. Children underwent baseline comprehensive ocular examinations in 2016 (at 48-60 months old) and the follow-up ocular examinations in 2017. A comprehensive questionnaire about children and their families was completed by their legal guardians. For children having reduced PVA at baseline, a follow-up questionnaire about potential factors concerning VA correction was completed. Reduced VA was defined as VA worse than 0.30 logMAR (Snellen equivalent 6/12, 20/40), and persistent reduced VA was defined as reduced PVA in both 2016 and 2017.

Results: Among 1448 participants with both eye examinations and questionnaires completed, prevalence of reduced UCVA, reduced PVA, and persistent reduced VA at age of 60-72 months were 5.94%, 3.04%, and 1.59% respectively. Causes for reduced PVA were refractive error (79.5%), amblyopia (18.2%), and amblyopia combined nystagmus (2.3%). Among 23 children having persistent reduced VA, causes of reduced PVA remained unchanged in 13 children and 4 children developed amblyopia from refractive error. Younger age (OR = 1.09 for each month decrease, p = 0.01) and non-breastfeeding (OR = 2.08, p = 0.03) were risk factors for reduced UCVA. Younger children with reduced UCVA were at higher risk of having reduced PVA (OR = 1.18 for each month decrease, p = 0.04). Children with siblings (OR = 5.95, p = 0.02) were more likely to have persistent reduced VA.

Conclusions: Future vision health promotion strategies among preschool children should focus on early vision-screening and timely refractive correction. Apart from children of non-breastfeeding mothers, attention should also be paid to children with siblings.

Under-five mortality and social determinants in africa: a systematic review.

Eur J Pediatr

Global Health and Tropical Medicine, GHTM, LA-REAL, Instituto de Higiene e Medicina Tropical, IHMT, Universidade NOVA de Lisboa, Lisbon, Portugal.

Purpose: Under-five mortality is a key public health indicator, highly responsive to preventive interventions. While global efforts have made strides in reducing mortality rates in this age group, significant disparities persist, particularly in Sub-Saharan Africa. This study aimed to systematically review the factors influencing under-five mortality in Africa, focusing on sociodemographic factors and health-related determinants.

Natural variations of adolescent neurogenesis and anxiety predict the hierarchical status of adult inbred mice.

Hierarchy provides a survival advantage to social animals in challenging circumstances. In mice, social dominance is associated with trait anxiety which is regulated by adult hippocampal neurogenesis. Here, we test whether adolescent hippocampal neurogenesis may regulate social dominance behavior in adulthood.

Salinization processes profoundly impact soil quality and health, altering physical structure, chemical composition, and biological activity, particularly concerning soil microbial populations. Microbial communities play a pivotal role in maintaining soil ecosystem multifunctionality (EMF). Understanding the response of microbial communities to salinity stress is crucial for sustainable soil management and enhancing ecosystem resilience in arid and semi-arid regions.

Excessive oxidative stress and persistent inflammation are key factors contributing to the formation of diabetic chronic wounds. Delivering antioxidants through a microenvironment-responsive hydrogel system can effectively enhance wound healing and tissue regeneration. In this study, we developed a novel pH- and glucose-responsive hydrogel using Schiff base reaction and phenyl borate group for intelligent antioxidant release.

Background: Burns among children and adolescents represent a significant global health burden, leading to substantial morbidity and disability. This study aimed to analyze the trends in burn incidence, prevalence, and years lived with disability (YLDs) from 1990 to 2021, and to project future trends to 2035, highlighting global and regional disparities.

Methods: We utilized data from the Global Burden of Disease (GBD) database covering 204 countries and territories.
