Folia Medica Indonesiana

Low birth weight (LBW) remains a major public health concern in low-resource and rural settings due to its strong association with neonatal morbidity and mortality. This study aimed to identify maternal determinants associated with LBW in a rural hospital in Indonesia. A retrospective cross-sectional review was conducted on 179 singleton deliveries between January 1st and December 31st, 2024, at Alimuddin Umar General Hospital. Maternal age, parity, anemia, preeclampsia, and gestational age at delivery were obtained from medical records and analyzed using bivariate and multivariate methods. Bivariate analysis showed that preterm birth (p < 0.001) and preeclampsia (p < 0.05) were significantly associated with LBW, whereas maternal age, parity, and anemia showed no significant associations. When adjusted for potential confounders in the multivariate analyses, both preeclampsia (p = 0.019; OR = 4.61; 95% CI: 1.29–16.55) and preterm birth (p < 0.001; OR = 14.60; 95% CI: 5.52–38.57) remained independent predictors of LBW. These findings suggest that preeclampsia and preterm birth are the main contributors to LBW in this setting. Strengthening antenatal care, particularly early detection and management of preeclampsia and prevention of preterm birth, may reduce the burden of LBW. Further studies including nutritional, socioeconomic, and antenatal care variables are recommended to identify independent risk factors more comprehensively.

Simulation Based Model For Canine Distemper Virus In Prey-Predator Dynamics, Mussa A. Stephano Dec 2025

Simulation Based Model For Canine Distemper Virus In Prey-Predator Dynamics, Mussa A. Stephano

Tanzania Journal of Science

This study investigates the dynamic interactions of a prey-predator ecosystem infected with Canine Distemper Virus (CDV), focusing on predation and disease transmission. A deterministic model, coupled with Monte Carlo simulations (MCS), employed to capture both stochastic variability and environmental fluctuations. The findings indicate that classical prey-predator cycles provide the baseline for population dynamics, but the introduction of CDV and environmental noise fundamentally alters system behavior. Initially, populations exhibit oscillations that gradually stabilize into dynamic equilibria. However, the disease persists within both prey and predator populations, suggesting endemicity rather than extinction. Predation plays a dual role in disease dynamics, while it …
