Background: Childbirth among adolescents and young mothers has been linked to various complications, including perinatal mortality, preterm births, low birth weight, and infections, which collectively contribute to the high burden of neonatal and maternal mortality. Despite some progress, the prevalence of skilled birth attendance, proven to improve maternal and newborn health outcomes, remains consistently low in Northern Nigeria. This study assessed the prevalence and determinants of Skilled Birth Attendance (SBA) among young women ages 15-24 years in Northern Nigeria.

Job stress is a critical factor of concern in police work across the world. While frustrations, exhaustion and emotional burnout in work places, particularly as they relate to police job, have been academically emphasized in more advanced climes, they are marginally addressed in less developed societies like Nigeria. Thus, this paper examines the psychological and physical impacts of job stress, workload, and burnout among police officers in Nigeria.

Background: Sexual violence is prevalent in higher education institutions in Nigeria and stakeholders have encouraged staff and students to blow the whistle whenever they fall victim to or are aware of any sexual violence case. However, there is lack of data about whether the staff and students of these institutions have the intention to blow the whistle internally (within the institution) or not. There is also a lack of data on the existing reporting mechanisms or preferred whistleblowing mechanisms in these institutions.

Despite its effectiveness in managing the motor symptoms of Parkinson's disease, levodopa therapy is often accompanied by adverse effects that can significantly reduce patients' quality of life. Hence, the need to detect levodopa has escalated among researchers and health experts. Herein, the intricacies of levodopa adsorption were studied using newly tailored fullerene-based adsorbents.

HIV is one of the most threatening health conditions with a highly increasing rate, affecting millions of people globally, and from its time of discovery until now, its potential cure cannot be explicitly defined. This challenge of having no/low effective drugs for the subjected virus has called for serious attention in the scientific world of virus disease therapeutics. Most of these drugs yields low effectiveness due to poor delivery; hence, there is a need for novel engineering methods for efficient delivery.

The capacity of South African Heulandite HEU zeolite to remove Pb and Cd ions from aqueous solution was investigated using batch experiments and molecular simulations studies. The effect of different factors on the adsorption of these ions onto the zeolite was investigated; contact time, initial metal ion concentration and the amount of HEU adsorbent. Molecular simulations was done using Monte Carlo and density functional theory.

Prcis: Patients' acceptance of glaucoma therapy was high overall in this study, but lower for surgery than for laser or medical therapy. Fear and cost were the leading reasons why patients declined recommended therapy and they were treatment-specific. Cost was the primary reason for declining medical and laser therapy, while fear was the most common reason for declining surgical therapy.

  • Prophages significantly influence the characteristics of pathogenic bacteria, yet their ecological and evolutionary roles, particularly in bacteria linked to gastric cancer, are not well understood.
  • A comprehensive analysis of 1,011 complete clinical genomes revealed that 29.5% contain prophages, with only 32.2% being complete, and their distribution varies by geography and ancestry but not by the disease status of hosts.
  • The study uncovered mechanisms of prophage inactivation and proposed a new model for regulating the lysogenic-lytic cycle, providing a deeper understanding of how prophages impact bacterial genetics and adaptation.

Soluble platelet selectin and platelets in COVID-19: a multifaceted connection.

Ann Med Surg (Lond)

August 2024

Department of Haematology and Blood Transfusion Science, Faculty of Medical Laboratory Science, Federal University Otuoke, Bayelsa State, Nigeria.

The COVID-19 pandemic has brought to light the intricate relationship between platelets, soluble platelet selectin (sP-selectin), and disease pathogenesis. Platelets, traditionally recognized for their role in hemostasis, have emerged as key contributors to the immunothrombotic complications observed in COVID-19 patients. Concurrently, elevated levels of sP-selectin, indicative of platelet activation and endothelial injury, have been consistently identified in COVID-19 patients and have shown associations with disease severity and adverse outcomes.

Introduction: The high neonatal mortality rate in low- and middle-income countries (LMICs) such as Nigeria has lasted for more than 30 years to date with associated nursing fatigue. Despite prominent hard work, technological improvements, and many publications released from the country since 1990, the problem has persisted, perhaps due to a lack of intervention scale-up. Could there be neglected discoveries unwittingly abandoned by Nigerian policymakers over the years, perhaps locked up in previous publications? A careful review may reveal these insights to alert policymakers, inspire researchers, and refocus in-country research efforts towards impactful directions for improving neonatal survival rates.

Article Synopsis
  • Africa has a high hypertension prevalence (46%), and schoolteachers are particularly at risk due to work and lifestyle factors, making it essential to understand these risks for better health interventions.
  • A study of 427 schoolteachers in Calabar, Nigeria, found a 32% prevalence of hypertension, with significant correlations linked to age and body mass index (BMI).
  • Teachers aged 30 and older, as well as those categorized as overweight or obese, faced greater odds of hypertension; therefore, health strategies should prioritize weight management for older educators.
