Background: Human papillomavirus (HPV) vaccine is effective in averting 70%-90% of all HPV-related diseases. The assessment of its awareness, uptake and willingness to pay (WTP) is important in Nigeria which is one of the developing countries where more than three-quarter of the global burden of HPV-related diseases occur. This study aimed to determine the sociodemographic factors associated with the awareness, uptake and WTP for HPV vaccine amongst undergraduates in a tertiary institution in North Central Nigeria.

The effectiveness of an m-Health intervention on the sexual and reproductive health of in-school adolescents: a cluster randomized controlled trial in Nigeria.

Background: The implementation of the country-wide comprehensive sexuality education (CSE) curriculum among in-school adolescents remains abysmally low and mHealth-based interventions are promising. We assessed the effect of a mHealth-based CSE on the sexual and reproductive health (SRH) knowledge, attitude and behaviour of in-school adolescents in Ilorin, northcentral Nigeria.

Methods: Using schools as clusters, 1280 in-school adolescents were randomised into intervention and control groups.

Influences of community engagement and health system strengthening for cholera control in cholera reporting countries.

The 2030 Global Task Force on Cholera Control Roadmap hinges on strengthening the implementation of multistranded cholera interventions, including community engagement and health system strengthening. However, a composite picture of specific facilitators and barriers for these interventions and any overlapping factors existing between the two, is lacking. Therefore, this study aims to address this shortcoming, focusing on cholera-reporting countries, which are disproportionately affected by cholera and may be cholera endemic.

Unpacking the Racial Gap: Helicobacter pylori Infection Clearance Among Different Racial Groups.

Introduction Helicobacter pylori (H. pylori) is a bacteria causing chronic stomach infections, influenced by various factors, including host traits and bacterial virulence. It uses both urease-dependent and independent mechanisms to survive acidic gastric environments.

Infarct Size With Incremental Global Myocardial Ischemia Times: Cyclosporine A in Donation After Circulatory Death Rat Hearts.

Background: We quantified the myocardial infarct size with varying global ischemia durations and studied the benefits of Cyclosporine A (CyA) in reducing cardiac injury in ex vivo and transplanted rat hearts.

Methods: Infarct size was measured after 15, 20, 25, 30, and 35 minutes of in vivo global ischemia (n = 34) and compared with control beating-heart donor (CBD) hearts (n = 10). For heart function assessment, donation after circulatory death (DCD) rat hearts (n = 20) were procured after 25 minutes of in vivo ischemia and reanimated ex vivo for 90 minutes.

Strengthening pathogen genomic surveillance for health emergencies: insights from the World Health Organization's regional initiatives.

The onset of the COVID-19 pandemic triggered a rapid scale-up in the use of genomic surveillance as a pandemic preparedness and response tool. As a result, the number of countries with in-country SARS-CoV-2 genomic sequencing capability increased by 40% from February 2021 to July 2022. The Global Genomic Surveillance Strategy for Pathogens with Pandemic and Epidemic Potential 2022-2032 was launched by the World Health Organization (WHO) in March 2022 to bring greater coherence to ongoing work to strengthen genomic surveillance.

The Path to Sustainable Healthcare: Implementing Care Transition Teams to Mitigate Hospital Readmissions and Improve Patient Outcomes.

Introduction Hospital readmissions within 30 days suggest care quality issues and increased mortality risks. They result from ineffective initial treatment, poor discharge planning, and inadequate post-acute care. These high readmission rates harm patient outcomes and financially strain healthcare institutions, inviting penalties and discouraging potential patients.

HIV Knowledge and Screening Practices among In-School Adolescents in a Semi-Urban Community of Osun State, Southwest Nigeria.

Background: Adolescents and youths are currently one of the main sub-populations responsible for most Human Immunodeficiency Virus (HIV) new cases in Nigeria due to their high-risk sexual practices. Yet, most Nigerian adolescents have poor HIV knowledge and are not aware of their HIV status.

Study Objectives: We assessed respondents' HIV knowledge, their attitude to screening, testing practice and identified predictors of HIV screening among youths (15-24 years old) in Iwo, Osun State, Nigeria.

Caregiving in a tertiary health institution in North Central Nigeria: Support types and financial burden.

Background: Caregivers play an important role in informal patient management. Identification of the support types and the financial challenges faced by caregivers will provide information on strategies to ease this burden. This study aimed to describe the support types and financial burden amongst caregivers in a tertiary hospital in North Central Nigeria.

Electron Transport Chain Inhibition to Decrease Injury in Transplanted Donation After Circulatory Death Rat Hearts.

Donation after circulatory death (DCD) donor hearts sustain ischemic damage and are not routinely used for heart transplantation. DCD heart injury, particularly reperfusion injury, is primarily mediated by releasing reactive oxygen species from the damaged mitochondria (complex I of the electron transport chain). Amobarbital (AMO) is a transient inhibitor of complex I and is known to reduce releasing reactive oxygen species generation.

COVID-19 mortality rate and its associated factors during the first and second waves in Nigeria.

COVID-19 mortality rate has not been formally assessed in Nigeria. Thus, we aimed to address this gap and identify associated mortality risk factors during the first and second waves in Nigeria. This was a retrospective analysis of national surveillance data from all 37 States in Nigeria between February 27, 2020, and April 3, 2021.

Meta-analysis shows forest soil CO effluxes are dependent on the disturbance regime and biome type.

Forest soil CO efflux (FCO ) is a crucial process in global carbon cycling; however, how FCO responds to disturbance regimes in different forest biomes is poorly understood. We quantified the effects of disturbance regimes on FCO across boreal, temperate, tropical and Mediterranean forests based on 1240 observations from 380 studies. Globally, climatic perturbations such as elevated CO concentration, warming and increased precipitation increase FCO by 13% to 25%.

A scoping review of facilitators and barriers influencing the implementation of surveillance and oral cholera vaccine interventions for cholera control in lower- and middle-income countries.

Background: Cholera still affects millions of people worldwide, especially in lower- and middle-income countries (LMICs). The Global Task Force on Cholera Control (GTFCC) has identified surveillance and oral cholera vaccines as two critical interventions to actualise the global roadmap goals-reduction of cholera-related deaths by 90% and decreasing the number of cholera endemic countries by half by 2030. Therefore, this study aimed to identify facilitators and barriers to implementing these two cholera interventions in LMIC settings.

Risk communication during health emergencies in Nigeria: What are its challenges?

Although globalization has been advantageous in facilitating the free movement of people, goods, and services, the ease of movement of cross-border pathogens has increased the risk of international public health emergencies in recent years. Risk communication is an integral part of every country's response during public health emergencies such as the coronavirus disease (COVID-19) pandemic. To effectively increase adherence to guidelines during health emergencies, it is essential to understand the impact of social, cultural, political, and environmental factors on people's behaviours and lifestyles in any given context, as well as how these factors influence people's perception of risks.

SARS-CoV-2 variants-associated outbreaks of COVID-19 in a tertiary institution, North-Central Nigeria: Implications for epidemic control.

The COVID-19 global pandemic is being driven by evolving SARS-CoV-2 variants with consequential implications on virus transmissibility, host immunity, and disease severity. Continuous molecular and genomic surveillance of the SARS-CoV-2 variants is therefore necessary for public health interventions toward the management of the pandemic. This study is a retrospective analysis of COVID-19 cases reported in a Nigerian tertiary institution from July to December 2021.

Seroprevalence of anti-SARS-CoV-2 specific antibodies in vaccinated and vaccine naïve adult Nigerians.

Background: Reports on the evaluation of immune responses to different COVID-19 vaccines are limited. Similarly, effects of age and gender have not been well explored as variables that could impact on the vaccine-induced antibody response. Therefore, seroprevalence of anti-SARS-CoV-2 specific antibodies in vaccinated and vaccine naïve adult Nigerians was determined in this study.
