Article Abstract
Background And Aims: Tuberculosis (TB) remains a major global cause of death, particularly in developing countries. This study aims to identify key risk factors contributing to high TB incidence in these nations, analyze regional variations, and assess how risk factors differ across continents.
Methods: We conducted a retrospective analysis using data from 70 developing countries spanning 2000 to 2020, sourced from the World Bank Open Data. Variables included TB incidence, HIV prevalence, smoking rates, literacy rates, undernourishment, and population density. A random-effects model was employed to examine the associations between these factors and TB incidence.
Results: HIV prevalence (coefficient = 37.53, 95% CI: 34.28-40.79), smoking (3.51, 2.99-4.02), undernourishment (1.56, 1.02-2.10), and population density (0.16, 0.07-0.24) showed significant positive associations with TB incidence. Literacy rate was negatively associated with TB incidence (-0.11, -0.54 to 0.33), though not significantly. These findings highlight the strong influence of socio-demographic and health-related factors on TB burden.
Conclusion: TB continues to pose a serious health challenge in developing countries. HIV control, reduction of undernourishment and smoking, and managing population density are critical to reducing TB incidence. Regional differences underscore the need for tailored prevention strategies.

Aim: We aimed to assess the impact of birth preparedness interventions among pregnant women on the improvement of their maternal and neonatal outcomes in low- and middle-income countries.
Methods: Randomized controlled trials from 2007 to 2023 that assessed birth preparedness interventions for pregnant women living in such countries were reviewed after searching on PubMed, CENTRAL, Embase, and CINAHL databases. This systematic review followed the Preferred Reporting Items for the Systematic Reviews and Meta-Analysis standards.

Introduction: Streptococcus pneumoniae is a major cause of lower respiratory infections, especially in children under 5 years old. While pneumococcal conjugate vaccines (PCVs) have reduced disease burden in many countries, data from low- and middle-income countries are still limited. The objective of this prospective, hospital-based, cross -sectional study was to measure the prevalence of pneumococcal colonization and identify circulating serotypes among children <5 years and their caregivers in Cambodia and India.

Background: Ectopic pregnancy (EP) represents a leading cause of maternal mortality in early gestation and a significant contributor to future reproductive impairment. Comprehensive understanding of global EP epidemiological patterns and their temporal evolution is crucial for developing holistic strategies to promote health equity and optimize allocation of medical resources worldwide.
Methods: Leveraging Global Burden of Disease (GBD) 2021 data, this investigation systematically examined age-standardized rates (ASRs) of EP incidence, prevalence, mortality, and disability-adjusted life years (DALYs) across 204 countries and 21 regions from 1990 to 2021.
