Oxygen deprivation, or hypoxia, during pregnancy poses a multifaceted challenge to maternal and fetal well-being, significantly impacting gestational outcomes. This comprehensive review endeavors to elucidate the intricate mechanisms and consequences of hypoxia on maternal health within the context of pregnancy. Through an exploration of the complex interplay between oxygen insufficiency, placental function, and maternal physiology, this review aims to unravel the far-reaching implications of hypoxia on pregnancy outcomes. The discourse encompasses the pivotal role of hypoxia in precipitating various pregnancy complications such as preeclampsia, gestational hypoxia, and intrauterine growth restriction (IUGR), shedding light on their underlying pathophysiological processes and potential therapeutic avenues. By synthesizing current knowledge, this review aims to advance our comprehension of hypoxia\'s impact on maternal health during gestation, fostering the development of targeted interventions to alleviate adverse outcomes associated with oxygen deprivation in pregnancy.

Anemia remains a prevalent complication in individuals living with Human Immunodeficiency Virus (HIV), exerting a significant impact on disease progression and patient prognosis. Platelet Distribution Width (PDW), an established measure reflecting platelet heterogeneity, has garnered attention as a potential prognostic marker for evaluating anemia severity in this patient population. This review provides a comprehensive analysis of the utility of PDW in prognosticating anemia severity in HIV patients, aiming to explore its clinical relevance, associations, and implications for disease management. The prevalence of anemia in HIV patients is discussed, emphasizing its multifactorial etiology and adverse effects on the overall health and prognosis of affected individuals. The introduction outlines the necessity for reliable prognostic indicators to assess anemia severity in the context of HIV and sets the stage for evaluating PDW as a potential solution. In conclusion, this review highlights the potential of PDW as a valuable prognostic marker for evaluating anemia severity in HIV patients, underscoring its potential impact on disease management and the need for continued research to validate and incorporate PDW measurements in routine clinical practice.

Platelets, conventionally recognized for their pivotal roles in hemostasis and thrombosis, have emerged as multifunctional players in immune responses. In the context of Human Immunodeficiency Virus (HIV) infection, platelets exhibit intricate interactions influencing viral pathogenesis, immune activation, and disease progression. This review aims to provide an in-depth analysis of the diverse roles played by platelets in modulating HIV infection, shedding light on their impact on viral dynamics, immune responses, and associated pathophysiological processes. The paper addresses platelet-driven alterations in coagulation pathways and endothelial function in the context of HIV, emphasizing their role in HIV-associated coagulopathies, endothelial activation, and consequent vascular dysfunction. Additionally, the involvement of platelets in the development of HIV-associated comorbidities such as cardiovascular complications, neurocognitive impairment, and systemic inflammation is discussed, delineating platelet-driven mechanisms contributing to the pathogenesis of these conditions and their implications for disease outcomes. In conclusion, the multifaceted roles of platelets in HIV infection underscore their significance beyond hemostasis, offering potential insights into therapeutic avenues and highlighting the need for further investigations to decode the complexity of platelet-driven modulation of HIV infection.
