Coagulation abnormalities in children with uncorrected congenital heart defects seen at a teaching hospital in a developing country.

Background: Coagulation abnormality is a significant complication and cause of mortality in children with uncorrected congenital heart defects (CHD). The aim of this study was to determine the prevalence of coagulation abnormalities and the associated factors in children with uncorrected CHD.

Method: A cross sectional study conducted to determine the prevalence of coagulation abnormalities among 70 children with uncorrected CHD aged six months to 17 years and 70 age and sex matched apparently healthy controls.

Porcine circovirus type 2 and its associated diseases in southwestern Nigeria: Farmers' perception and level of awareness.

Objective: Porcine circovirus type 2 (PCV2) is one of the most important causative agents of swine diseases that pose a global economic threat. Presently, there is little or no information on the perception and awareness of PCV2 and its associated effects among pig farmers in Nigeria. Therefore, this research was carried out to describe pig farmers' views, awareness, and likely impact of PCV2 and its associated postweaning multisystemic wasting syndrome (PMWS) on pig production in the southwestern region of Nigeria.

Real-world use and outcomes of dolutegravir-containing antiretroviral therapy in HIV and tuberculosis co-infection: a site survey and cohort study in sub-Saharan Africa.

Introduction: Dolutegravir is being scaled up globally as part of antiretroviral therapy (ART), but for people with HIV and tuberculosis co-infection, its use is complicated by a drug-drug interaction with rifampicin requiring an additional daily dose of dolutegravir. This represents a disadvantage over efavirenz, which does not have a major drug-drug interaction with rifampicin. We sought to describe HIV clinic practices for prescribing concomitant dolutegravir and rifampicin, and characterize virologic outcomes among patients with tuberculosis co-infection receiving dolutegravir or efavirenz.

Effects of cannabidiol on weight and fasting blood sugar with chronic and subchronic haloperidol administration.

Objectives: The duration of administration (e.g., subchronic or chronic) of haloperidol may influence its adverse effects.

Promising disruptors of p53-MDM2 dimerization from some medicinal plant phytochemicals: a molecular modeling study.

Cancer is a major global health issue that has a high mortality rate. p53, which functions as a tumor suppressor, is critical in preventing tumor development by regulating the cell cycle and inducing apoptosis in damaged cells. However, the tumor suppressor function of p53 is effectively inhibited by its direct interaction with the hydrophobic cleft of MDM2 protein via multiple mechanisms As a result, restoring p53 activity by blocking the p53-MDM2 protein-protein interaction has been proposed as a compelling therapeutic strategy for cancer treatment.

Factors influencing the implementation of TB screening among PLHIV in selected HIV clinics in Ghana: a qualitative study.

Background: Decreasing the burden of Tuberculosis (TB) among PLHIV through TB screening is an effective intervention recommended by the World Health Organization (WHO). However, after over a decade of implementation in Ghana, the intervention does not realize the expected outcomes. It is also not well understood whether this lack of success is due to implementation barriers.

Background: There is scarce information about the occurrence of extended-spectrum β-lactamases (ESBLs) in a serovar Typhi () from patients with typhoid fever.

Objective: To study the antimicrobial resistance and ESBL encoding genes among isolates in aforesaid patients from Lagos, Nigeria.

Methods: isolates were collected from blood samples of typhoid fever patients from 4 academic medical centers in Lagos, Nigeria.

A mixed-method study exploring experiences, perceptions, and acceptability of using a safe delivery mHealth application in two district hospitals in Rwanda.

Background: Innovative use of mobile health (mHealth) technology in timely management of childbirth complications is a promising strategy, but its evidence base is limited. The Safe Delivery mHealth Application (SDA) is one of the recent mhealth applications (loaded in smartphones) which is a clinical decision support and training tool for basic emergency obstetric and newborn care (BEmONC). This paper describes, the health providers' experiences, perceptions, and acceptability of using the SDA, as well as the perceptions of key stakeholders.

"Is the health system ready?" A qualitative exploration of stakeholders' opinions about the feasibility of preconception care services in the Nigerian health system.

Background: Preconception care (PCC) services aim to improve reproductive health outcomes through the provision of biomedical, behavioural and social health interventions to women and couples before conception occurs. Countries that have deployed PCC services have policies that guide the services provided. In Nigeria, PCC is poorly developed and is often provided in an opportunistic manner with no guidelines in place to direct the provision.

Mechanism of Viral Suppression among HIV Elite Controllers and Long-Term Nonprogressors in Nigeria and South Africa.

A subgroup among people living with HIV (PLHIV) experience viral suppression, sometimes to an undetectable level in the blood and/or are able to maintain a healthy CD4+ T-cell count without the influence of antiretroviral (ARV) therapy. One out of three hundred PLHIV fall into this category, and a large sample of this group can be found in areas with a high prevalence of HIV infection such as Nigeria and South Africa. Understanding the mechanism underpinning the nonprogressive phenotype in this subgroup may provide insights into the control of the global HIV epidemic.

Digital sexually transmitted infection and HIV services across prevention and care continuums: evidence and practical resources.

Increased demand for sexual health services (including prevention and treatment) have spurred the development of digital STI/HIV services. Earlier advances in testing technologies opened the door for self-testing and self-sampling approaches, in line with broader self-care strategies. Advances in HIV management mean that many people are living well with HIV and no longer need intensive in-person monitoring, whereas those at-risk of HIV are recommended to have regular asymptomatic STI screening and pre-exposure prophylaxis.

Associations between COVID-19 testing status, non-communicable diseases and HIV status among residents of sub-Saharan Africa during the first wave of the pandemic.

Background: This study determined if non-communicable disease status, HIV status, COVID-19 status and co-habiting were associated with COVID-19 test status in sub-Saharan Africa.

Methods: Data of 5945 respondents age 18-years-old and above from 31 countries in sub-Saharan Africa collected through an online survey conducted between June and December 2020, were extracted. The dependent variable was COVID-19 status (testing positive for COVID-19 and having symptoms of COVID-19 but not getting tested).

This article provides an overview of the SARS-CoV-2 variant Omicron (B.1.

Understanding factors that promote uptake of HIV self-testing among young people in Nigeria: Framing youth narratives using the PEN-3 cultural model.

It is important to understand how to frame the formats for promoting HIV self-testing to increase uptake among young people. In this study, we used a culture-centered model to understand the narratives of HIV self-testing preferences among young people in Nigeria. We conducted a crowdsourcing contest to solicit ideas surrounding HIV self-testing promotion among young people (10-24 years) in Nigeria from October to November 2018 as part of the 2018 World AIDS Day event.

16S rRNA metagenomics data on the bacterial communities in integrated poultry-fish farm ponds.

In an integrated poultry-fish (IPF) farming system, fish and bird are reared simultaneously. It is a common practice in Sub-Saharan Africa countries like Nigeria, Cameroon, Madagascar, and Benin, offering economic benefits to farmers and minimizing farm running costs. It seems like another way for farmers to manage poultry waste as it is a common practice in IPF farm settings to feed reared fishes with wastes emanating from the poultry.

COVID-19, economic problems, and family relationships in eight Middle East and North African countries.

Objective: The aim was to assess the reported family relationships during the COVID-19 pandemic and the association between these relationships and individual, interpersonal, and country-level income in eight Middle East and North Africa (MENA) countries.

Background: COVID-19 causes fear of infection, loss of loved ones, and economic problems that may affect family relationships.

Methods: Data were collected from eight MENA countries using an online survey (July-August 2020).

Review of 2022 WHO guidelines on the control and elimination of schistosomiasis.

Schistosomiasis is a helminthiasis infecting approximately 250 million people worldwide. In 2001, the World Health Assembly (WHA) 54.19 resolution defined a new global strategy for control of schistosomiasis through preventive chemotherapy programmes.

Integrated virtual screening and molecular dynamics simulation revealed promising drug candidates of p53-MDM2 interaction.

In the vast majority of malignancies, the p53 tumor suppressor pathway is compromised. In some cancer cells, high levels of MDM2 polyubiquitinate p53 and mark it for destruction, thereby leading to a corresponding downregulation of the protein. MDM2 interacts with p53 via its hydrophobic pocket, and chemical entities that block the dimerization of the protein-protein complex can restore p53 activity.

Adopting an heterologous prime-boost strategy in COVID-19 vaccination: the need for locally generated evidence in Africa.

The reduction in the severity and prevalence of COVID-19 has been largely due to the rapid development and deployment of COVID-19 vaccines. Consequently, WHO, in partnership with the Coalition for Epidemic Preparedness Innovation, GAVI, the Vaccine Alliance, set up the COVID-19 Vaccines Global Access (COVAX) Initiative. The goal of this initiative is to prevent discrimination between high and low-income/middle-income countries and ensure equitable vaccine distribution.
