The Dynamic Impacts of Serial Prevention-and-Control Policies Against COVID-19 Pandemic on Residents' Emergency Medical Service Demands in China Pre- and Post-Reopening: An Observational Study.

Background: China has implemented serial prevention-and-control policies against COVID-19 pandemic pre- and post-reopening, yet it was unclear whether these policy adjustments resulted in changes in residents' emergency medical services (EMS) demands.

Objectives: We aimed to assess the impacts of gradual loosening and reopening policies against the COVID-19 pandemic on residents' EMS demands.

Methods: We conducted an observational study using a data set of 42,909 EMS call records from Nanning Emergency Medical Center during November 2022 to January 2023.

Timeliness and completeness of serial routine vaccinations among 8062 rural children in southwest China during the COVID-19 pandemic: A multi-stage stratified cluster sampling survey in 1094 villages.

Introduction: The COVID-19 pandemic disrupted routine vaccination, previous studies had revealed the drop on routine-vaccination coverage in many areas, but no study gave considerable attention to the timeliness and completeness of routine vaccination in rural China at this immunization crisis. This study assessed the timeliness and completeness of serial routine vaccinations among children in rural China, aimed to discover the impact of the pandemic, and provide evidence for further immunization catch-up and supplementary immunization activities.

Methods: We conducted a multi-stage stratified cluster survey among 8404 children aged 9-48 months in rural Guangxi.

Global, regional, and national burden of thalassemia during 1990-2019: A systematic analysis of the Global Burden of Disease Study 2019.

Introduction: Thalassemia represents a significant public health challenge globally. However, the global burden of thalassemia and the disparities associated with it remain poorly understood. Our study aims to uncover the long-term spatial and temporal trends in thalassemia at global, regional, and national levels, analyze the impacts of age, time periods, and birth cohorts, and pinpoint the global disparities in thalassemia burden.

The long-term spatio-temporal trends in burden and attributable risk factors of major depressive disorder at global, regional and national levels during 1990-2019: a systematic analysis for GBD 2019.

Aims: Caused by multiple risk factors, heavy burden of major depressive disorder (MDD) poses serious challenges to public health worldwide over the past 30 years. Yet the burden and attributable risk factors of MDD were not systematically known. We aimed to reveal the long-term spatio-temporal trends in the burden and attributable risk factors of MDD at global, regional and national levels during 1990-2019.
