Risk Stratification in Obstetrics: An Integrated Approach to Maternal Health

Open Journal of Obstetrics and Gynecology 2024年第6期14卷 903-910页

作者： Taina Crespo Mendonca Bianca Beatriz Soares dos Reis Júlia Cruz Coelho Antônio de oliveira Battistini Pestana Vitória Carolina Barreto Negri Alvaro Augusto Trigo Department of Medicine University of Franca Franca Brazil

Introduction: Prenatal care is crucial for maternal and fetal health, highlighting the importance of obstetric risk stratification. This enables personalized care, avoiding unnecessary interventions and reducing costs. Conditions such as first trimester bleeding, spontaneous abortion, gestational trophoblastic disease, and ectopic pregnancy require specific approaches. Early identification of these complications is vital, especially in urgent and emergency obstetric cases, which demand immediate hospital attention. Objective: Comprehensive review of first trimester pathologies and gestational hypertension, focusing on obstetric risks and personalized prenatal management. Methods: Literature review on bleeding and gestational hypertension. Results: The study provides a detailed analysis of pathologies associated with first trimester uterine bleeding and hypertensive disorders, focusing on obstetric risk stratification. The main causes of maternal and fetal mortality are hypertensive disorders, hemorrhages, infections, childbirth complications, and abortion. Spontaneous abortion is common, with different classifications, ranging from threatened to missed abortion. Infected abortion is a severe complication. Brazil has restrictive abortion laws, but many unsafe abortions occur, resulting in high public health costs. Pharmacological treatment with misoprostol is a safe option. Other pathologies include gestational trophoblastic disease, ectopic pregnancy, and placenta previa. Preeclampsia and eclampsia are severe conditions requiring immediate treatment to avoid complications. Conclusion: Early identification and management of obstetric risk factors, such as uterine bleeding, are essential for positive maternal and fetal outcomes. A multidisciplinary approach is fundamental.

Evaluating the Effects of Graviton Redshift upon Spiral Galaxy Rotation Curves, Surface Brightness Magnitudes and Gravitational Lensing

引用

Journal of High Energy Physics, Gravitation and Cosmology 2024年第3期10卷 967-985页

作者： Firmin J. oliveira East Asian Observatory James Clerk Maxwell Submillimetre Telescope Hilo USA

The effects of the gravitational redshift of gravitons upon spiral galaxy rotation energy are compared to the standard mass to light analyses in obtaining rotation curves. The derivation of the total baryonic matter compares well with the standard theory and the rotation velocity is matched to a high precision. The stellar mass distributions obtained from the fit with graviton energy loss are used to derive the surface brightness magnitudes for the galaxies, which agree well with the observed measurements. In a new field of investigation, the graviton theory is applied to the observations of gravitational lenses. The results of these applications of the theory suggest that it can augment the standard methods and may eliminate the need for dark matter.
