Double stigma: a cross-sectional study of Lassa patients with hearing loss in North Central Nigeria.

Introduction: Lassa fever is a zoonotic infectious disease endemic in West Africa with a high case-fatality rate and reported stigmatization of surviving patients. This study examines discrimination among survivors of Lassa fever (LF) complicated by hearing loss (HL).

Methods: This cross-sectional qualitative study used an in-depth interview guide to collect information from patients with HL about their experience of stigma.

Performance evaluation of SARS-CoV-2 rapid diagnostic tests in Nigeria: A cross-sectional study.

The COVID-19 pandemic challenged health systems globally. Reverse transcription polymerase chain reaction (RT-PCR) is the gold standard for detecting the presence of SARS-CoV-2 in clinical samples. Rapid diagnostic test (RDT) kits for COVID-19 have been widely used in Nigeria.

FACTORS INFLUENCING ANTI-POLYRIBOSYLRIBITOL PHOSPHATE TITRES IN YOUNG NIGERIAN CHILDREN PRIMED WITH DTWP-HEPB-HIB VACCINE.

Introduction: Recent research suggests that variation in vaccine-induced immune responses is influenced by genetic, nutritional, environmental, and vaccine-related factors, with significant vaccine design and programmatic policy implications. Haemophilus influenzae type b (Hib) Conjugate Vaccine (HCV) stimulates the production of antiPolyribosylribitol phosphate (anti-PRP) antibodies, which confer long-term protection against invasive Hib disease and nasopharyngeal colonization by Hib at titre levels ≥1μg/mL and ≥5μg/mL respectively. This study investigated the influence of these factors on the protective anti-PRP levels in children aged 6-23 months in Obi L.

SEROPROTECTION RATE OF HAEMOPHILUS INFLUENZAE TYPE B CONJUGATE VACCINE AND ASSOCIATED CLINICAL OUTCOMES AMONG NIGERIAN CHILDREN AGED 6 TO 23 MONTHS.

Introduction: Haemophilus influenzae type b (Hib) causes invasive infections almost exclusively in under- fives with those aged 6-23 months being the most vulnerable. In Nigeria, it is estimated to cause nearly 400,000 annual infections and another 30,000 under-five mortality attributable to pneumonia and meningitis alone. The Hib Conjugate Vaccine (HCV) is in widespread use to combat these devastating infections.

Antenatal jaundice instruction and acute bilirubin encephalopathy in Nigeria.

Background: Acute Bilirubin Encephalopathy (ABE) is common in Nigeria. Parents' inability to recognize jaundice and delays in seeking care are significant barriers to its prevention.

Methods: We compared associations of (1) interactive antenatal maternal jaundice instruction with postnatal reinforcement, (2) standard postnatal instruction, and (3) no maternal instruction with the incidence of ABE among 647 jaundice admissions stratified for risk factors identified in initial descriptive analysis.

Quantitative assessment of umbilical cord care practices amongst mothers in Jos, Plateau State, Nigeria.

Introduction: A newly cut neonatal umbilical stump is a potential portal of pathogen entry leading to omphalitis. Neonatal sepsis can complicate omphalitis, but good cord care practices can reduce this risk.

Objective: The objective of this study was to assess umbilical cord care practices in tertiary-, secondary- and primary-level healthcare facilities in Jos, Nigeria.

Analysis of sensorineural hearing loss in patients attending an otolaryngology clinic in North Central Nigeria.

Hearing loss is the third leading cause of years lived with disability. Approximately 1.4 billion people have hearing loss, of which 80% reside in low- and middle-income countries with limited audiology and otolaryngology care available to them.

Epidemiological review of confirmed Lassa fever cases during 2016-2018, in Plateau State, North Central Nigeria.

Lassa fever (LF) is endemic in West Africa and constitutes a significant public health concern due to its potential for epidemics and associated high mortality. The first reported case and management of Lassa fever in Plateau State occurred more than 50 years ago. We set out to undertake a three-year epidemiological review of LF cases in Plateau State, North Central Nigeria.

An assessment of improved outcomes using low-cost bubble CPAP in very low birthweight neonates in a Nigerian tertiary hospital.

Respiratory distress contributes to the high burden of preterm mortality globally. The aim of our study was to evaluate the use of low-cost Bubble Continuous Positive Airway Pressure devices for treating respiratory distress and their outcomes in preterm infants weighing <1500g. Data was extracted from admission records of 211 infants over two distinct 4-year periods before and after introduction of bCPAP.

Immunization status of children 1-5 years old seen at the Emergency Pediatric Unit of a Teaching Hospital in North-Central Nigeria.

Introduction: Advocacy for immunization has been ongoing in various parts of the world to improve immunization uptake amongst children. Annually within the last decade, immunization has been reported to avert over two million deaths globally. This study determined the current immunization status of children 1-5 years of age, the factors affecting immunization uptake and recommends ways of improving immunization uptake among children presenting at an Emergency Pediatric Unit (EPU).

Prevalence and correlates of stunting among the school-age population in North-Central Nigeria.

Introduction: Stunting remains a huge public health concern among developing Nations. However, the burden of this problem among the school-age population appears to have been eclipsed by most nutritional surveys that focus more on the under-fives. This study aimed to demonstrate the prevalence, and identify socio-demographic factors that are associated with stunting among the school-age children in North central Nigeria.

Head Circumference of Babies at Birth in Nigeria.

Background And Objectives: Measuring head circumference (HC) of newborns is an important tool for evaluating intra-uterine brain development. HC reference charts currently in use in Nigeria are not representative of the local population. We thus present locally derived HC reference data for Nigerian infants at birth.

Pathogenesis, diagnostic challenges and treatment of zika virus disease in resource-limited settings.

The association of Zika virus (ZIKV) infection with congenital malformation and neurological sequelae has brought significant global concern. Consequently, the World Health Organization (WHO) declared it "a public health emergency of International concern" on 1 February, 2016. A critical review of its pathogenesis would lead to a better understanding of the clinical features and the neurological complications.

Low Zika virus seroprevalence among pregnant women in North Central Nigeria, 2016.

Background: Zika virus (ZIKV) has been known for decades in Africa but contemporary data is lacking at large.

Objectives: To describe the seroepidemiology of ZIKV in North Central Nigeria.

Study Design: We performed a cross-sectional study at six health care facilities in North Central Nigeria from January to December 2016.

Factors influencing irradiance of locally fabricated phototherapy devices in Jos, north-central Nigeria.

Locally fabricated phototherapy devices (LFPDs) are widely used in Nigeria for the treatment of neonatal jaundice. Ours was a cross-sectional observational study of all LFPDs in major hospitals in Jos between January and March 2015. We evaluated a total of 24 LFPDs.

Factors associated with antiretroviral treatment interruption in human immunodeficiency virus (HIV)-1-infected children attending the Jos University Teaching Hospital, Jos, Nigeria.

Background: Interrupting anti-retroviral therapy (ART) for any number of reasons is an indication of a compromised adherence to ART. Several factors, including the pill burden from other drugs used in treating co-infections in children with human immunodeficiency virus (HIV), may influence ART adherence. The aim of this study was to identify the factors associated with ART interruption in HIV-1-infected children.

Immunogenicity and safety of the candidate RTS,S/AS01 vaccine in young Nigerian children: a randomized, double-blind, lot-to-lot consistency trial.

Background: For regulatory approval, consistency in manufacturing of vaccine lots is expected to be demonstrated in confirmatory immunogenicity studies using two-sided equivalence trials. This randomized, double-blind study (NCT01323972) assessed consistency of three RTS,S/AS01 malaria vaccine batches formulated from commercial-scale purified antigen bulk lots in terms of anti-CS-responses induced.

Methods: Healthy children aged 5-17 months were randomized (1:1:1:1) to receive RTS,S/AS01 at 0-1-2 months from one of three commercial-scale purified antigen bulk lots (1600 litres-fermentation scale; commercial-scale lots), or a comparator vaccine batch made from pilot-scale purified antigen bulk lot (20 litres-fermentation scale; pilot-scale lot).
