Liver cell cancer surveillance practice in Nigeria: Pitfalls and future prospects.

Hepatocellular carcinoma (HCC) is a disease of public health concern in Nigeria, with chronic hepatitis B and C infections contributing most to the disease burden. Despite the increasing incidence of HCC, surveillance practices for early diagnosis and possible cure are not deeply rooted in the country. This article aims to review the current status of HCC surveillance in Nigeria, stressing the encounters, breaches, and potential prospects.

Immune response to hepatitis B vaccine among children under 5 years in Africa: a meta-analysis.

Background: Hepatitis B virus (HBV) infection in Africa is mostly acquired before the age of 5 years through vertical or horizontal routes. While all the countries in the World Health Organization African region have introduced HBV vaccination into their national immunization programs, the rate of protective immune response to HBV vaccine among children in Africa has not been systematically synthesized. In this study, we estimated the HBV vaccine seroprotection rate (defined as anti-HBs titer ≥ 10 IU/L) and the associated factors among under-five children who completed a primary series of HBV vaccination in Africa.

Metagenomic Detection and Genetic Characterization of Human Sapoviruses among Children with Acute Flaccid Paralysis in Nigeria.

Using a metagenomic sequencing approach on stool samples from children with Acute Flaccid Paralysis (AFP), we describe the genetic diversity of Sapoviruses (SaVs) in children in Nigeria. We identified six complete genome sequences and two partial genome sequences. Several SaV genogroups and genotypes were detected, including GII (GII.

Qualitative healthcare worker survey: Retrospective cross-sectional case study on COVID-19 in the African context.

Background: Despite the presence of COVID-19 epidemiologic data in Africa, there are gaps in the understanding of healthcare workers' concerns and fears early in the pandemic.

Methods: A retrospective cross-sectional multi-country pan-African qualitative survey case study on the perceived effects of the COVID-19 pandemic on healthcare workers in the continent focused specifically on personal safety and misinformation. The survey was distributed to 13 countries via snowball sampling of practitioners between April 22 and May 15, 2020.

COVID-19 in Africa: Survey Analysis of Impact on Health-Care Workers.

As coronavirus disease 2019 (COVID-19) spreads across Africa, little is known about the impact of the pandemic on health-care workers (HCWs) in the region. We designed an anonymous survey distributed via e-mail and phone messaging to 13 countries through the African Hepatitis B Network. We obtained 489 analyzable responses.

Risk of Healthcare Worker Burnout in Africa during the COVID-19 Pandemic.

COVID-19 is now impacting every country in Africa and healthcare workers (HCWs) across the continent remain susceptible to professional burnout. We designed a 43-question survey addressing multiple aspects of the COVID-19 pandemic. The survey was anonymous, distributed via email and phone messaging to 13 countries in Africa.

Hepatitis B Awareness and Vaccination Patterns among Healthcare Workers in Africa.

Hepatitis B virus (HBV) vaccination patterns and the understanding of its risks among healthcare workers (HCWs) is a critical step to decrease transmission. However, the depth of this understanding is understudied. We distributed surveys to HCWs in 12 countries in Africa.

Characterization of hepatitis delta virus strains spreading in Abuja, Nigeria.

Hepatitis delta virus (HDV) is responsible for the most severe form of liver disease in humans. So far, eight genotypes (HDV-1 to -8) have been individualized worldwide. Little is known about HDV strains that spread in Nigeria.

Impact of Colocasia esculenta extract and fractions on high-fat diet-induced changes in body weight, adipose tissue and liver of rats.

The objective of the present study was to explore on the possible protective effects of the saponins and alkaloid-rich fractions of Colocasia esculenta L. Schott leaves on high-fat diet-induced changes in rats. High-fat diet (HFD)-fed rats were treated orally with 10mg/kg b.

Detection and circulation of hepatitis B virus immune escape mutants among asymptomatic community dwellers in Ibadan, southwestern Nigeria.

Background: In 2012, the first Nigerian Hepatitis B Virus (HBV) immune escape mutant (IEM) case was detected in a pregnant woman in southwestern Nigeria. Consequently, this study was designed to investigate the presence and possible circulation of IEMs amongst asymptomatic community dwellers in southwestern Nigeria.

Methods: Blood specimens collected from 438 asymptomatic community dwellers were screened for HBsAg using ELISA technique.

Detection of hepatitis B virus isolates with mutations associated with immune escape mutants among pregnant women in Ibadan, southwestern Nigeria.

Perinatal transmission of hepatitis B virus (HBV) and its associated immune escape mutants (IEMs), is the major vehicle through which a population of chronically infected people who serve as infectious HBV reservoirs is maintained in communities. Therefore, to assess the risk of perinatal transmission, 272 pregnant women attending ante-natal clinics in Ibadan metropolis, southwestern, Nigeria, were screened for HBsAg using ELISA technique. Samples positive for HBsAg were subjected to HBV DNA detection by PCR amplification of the S-gene and amplicon sequencing.
