- ItemAntioxidants and Pregnancy Complications(Clinical Journal of Obstetrics and Gynecology, 2024-01-25) Emmanuel Ifeanyi ObeaguPregnancy complications present signiϐicant challenges, impacting maternal health and fetal development. Oxidative stress, a key contributor to various pregnancy-related disorders such as preeclampsia, gestational diabetes mellitus (GDM), and preterm birth, has spurred interest in exploring antioxidant interventions. Antioxidants, known for their ability to counteractoxidative damage, have emerged as potential therapeutic agents to mitigate these complications. This paper synthesizes current knowledge on the role of antioxidants in pregnancy, elucidating their mechanisms of action, sources, and impact on oxidative stress-related complications. It examines diverse antioxidant compounds, including vitamins C and E, selenium, and natural phytochemicals, highlighting their potential to modulate oxidative stress pathways and promote maternal-fetal wellbeing. Furthermore, this paper critically analyzes clinical studies, meta-analyses, and preclinical research exploring the efficacy and safety of antioxidant supplementation during pregnancy. It discusses the complexities surrounding optimal dosages, timing, and formulations of antioxidants, aiming to delineate strategies for their integration into prenatal care. In conclusion, this review provides insights into the promising role of antioxidants as therapeutic strategies to alleviate pregnancy complications associated with oxidative stress. It highlights avenues for future research, advocating for a deeper understanding of antioxidant mechanisms and their optimalutilization in prenatal care to enhance maternal and fetal health outcomes.
- ItemAn Insight of Interleukin -6 and Fibrinogen: In Regulating the Immune System(Journal of Biomedical Sciences, 2022) Emmanuel Ifeanyi Obeagu; Emmanuel Muhimbura; Byamungu Pahari; Kagenderezo; Sarah Nakyeyune; Getrude Uzoma ObeaguThe role of the liver as a critical part of the immune system involved in both innate and adaptive immunity. As a major source of acute phase proteins, including components of the complement system. Hepatocytes are an important part of innate immunity and play an important role in controlling inflammatory responses throughout the body. Acute-phase protein production in hepatocytes is controlled by various cytokines released during the inflammatory process, with IL-6 and IL-1 type cytokines acting as key regulators, cascading and synergistic regulation or it functions as a cascade network with inhibition. Effects on acute-phase protein expression. The pro inflammatory cytokine interleukin-6 is an endogenous biochemical active during B cell maturation and inflammatory processes. Interleukin-6 plays an important role in regulating acute-phase protein synthesis in human hepatocytes
- ItemAnemia as a Prognostic Marker for Disease Progression in HIV Infection(IAA Journal of Biological Sciences, 2023) Emmanuel Ifeanyi Obeagu; Getrude Uzoma Obeagu; Esther Ugo Alum; Okechukwu Paul-Chima UgwuAnemia, a prevalent hematologic manifestation in individuals living with Human Immunodeficiency Virus (HIV) infection, has garnered considerable attention as a prognostic indicator for disease progression and adverse clinical outcomes. This abstract presents a comprehensive review elucidating the intricate relationship between anemia and the progression of HIV infection, incorporating epidemiological trends, underlying pathophysiological mechanisms, clinical implications, and prognostic significance. Despite advances in antiretroviral therapy (ART), anemia remains a frequent complication in HIV infected individuals, posing substantial challenges to patient management. This paper aims to provide a nuanced understanding of anemia's role as a prognostic marker, surpassing its conventional characterization as a hematologic abnormality in the context of HIV infection. Anemia's role as a predictive marker for adverse clinical outcomes in HIV patients is explored, encompassing increased mortality rates, heightened risk of opportunistic infections, accelerated disease progression, and compromised quality of life. The review delves into its prognostic significance, shaping therapeutic decisions and prognostic assessments. This paper encapsulates the criticality of anemia as a prognostic marker for disease progression in HIV infection. Understanding its epidemiology, pathophysiological mechanisms, clinical implications, and prognostic significance is pivotal for informed clinical decision-making, prognostic assessments, and optimizing care paradigms in HIV management.
- ItemInhalation Effect of Insecticides on Coagulation Profiles of Rabbits(Asian Hematology Research Journal, 2022-09-13) Emily Funmilayo Eyitayo; Olusegun Taiwo Oke a; Dorcas Yetunde Obazee; Emmanuel Ifeanyi ObeaguBackground: High malaria burden has led to the increase use of insecticides in the tropics and subtropics. This study thus aimed at assessing the effect of insecticides inhalation on coagulation profile using experimental animal model. Methods: Sixteen adult male rabbits divided into four groups A, B, C and D. Group A, B and C were exposed to 20 ml of pyrethroid insecticides containing 0.05% pralletrin and 0.15% cyfluthrin by inhalation for 10 mins, 20 mins, and 30mins respectively. Group D served as the control and was not exposed. Baseline study was done on all the animals before grouping for exposure. The pyrethroid insecticides was soaked in cotton wool (2.5g) in a container that was able to prevent the animal from ingesting it, which was placed inside the room A, B and C for 10 mins, 20 mins and 30 mins respectively. The rabbits were exposed for three weeks and samples were collected at the end of each week. Exposure was discontinued after day 21 and Samples were collected again on day 28 and 35 respectively which is the fourth and fifth week. All the animals were monitored twice daily for clinical signs like jerky movement, skin scratching, licking of legs and other body parts. Results: Data analysis revealed that there was significant effect of inhalation of insecticides on coagulation profile of rabbits at 10 min, 20 mins and 30 mins of exposure. There was significant decreased in PTTK and INR values. But, there was no significant effect on prothrombin time
- ItemTrauma care and referral patterns in Rwanda: Implications for trauma system development(Canadian journal of surgery, 2015-11-09) Ntakiyiruta, Georges., etalBackground: Trauma remains a leading cause of death worldwide. The development of trauma systems in low-resource settings may be of benefit. The objective of this study was to describe operative procedures performed for trauma at a tertiary care facility in Kigali, Rwanda, and to evaluate geographical variations and referral patterns of trauma care. Methods: We retrospectively reviewed all prospectively collected operative cases performed at the largest referral hospital in Rwanda, the Centre Hospitalier Universitaire de Kigali (CHUK), between June 1 and Dec. 1, 2011, for injury-related diagnoses. We used the Pearson χ² and Fisher exact tests to compare cases arising from within Kigali to those transferred from other provinces. Geospatial analyses were also performed to further elucidate transfer patterns. Results: Over the 6-month study period, 2758 surgical interventions were performed at the CHUK. Of these, 653 (23.7%) were for trauma. Most patients resided outside of Kigali city, with 337 (58.0%) patients transferred from other provinces and 244 (42.0%) from within Kigali. Most trauma procedures were orthopedic (489 [84.2%]), although general surgery procedures represented a higher proportion of trauma surgeries in patients from other provinces than in patients from within Kigali (28 of 337 [8.3%] v. 10 of 244 [4.1%]). Conclusion: To our knowledge, this is the first study to highlight geographical variations in access to trauma care in a low-income country and the first description of trauma procedures at a referral centre in Rwanda. Future efforts should focus on maturing prehospital and interfacility transport systems, strengthening district hospitals and further supporting referral institutions.
