Trends in pediatric tuberculosis diagnosis utilizing xpert Mycobacterium tuberculosis/Rifampicin in a poor-resource, high-burden region: A retrospective, multicenter study.

Background: The burden of tuberculosis (TB) in Nigeria remains high, and diagnosis in children, a challenge. We aimed to document yield from Xpert Mycobacterium tuberculosis/rifampicin (MTB/RIF) as a mode of diagnosis for children and the variables associated with a positive result. Methods: This was a retrospective review of TB treatment cards of children aged 0-15 years managed from January 2017 to December 2021 across six public tertiary institutions in Nigeria. The data obtained were analyzed using the descriptive and inferential statistics. Statistical significance was set at P < 0.05. Results: Of 1489 children commenced on TB treatment, 1463 (97.9%) had sufficient data for analysis the median age of study participants was 60 months (interquartile range [IQR]: 24, 120), and 814 (55.6%) were males. Xpert MTB/RIF test was performed in 862 (59%) participants and MTB was detected in 171 (19.8%) participants, of which 6.4% (11/171) had RIF resistance reported. The use of Xpert MTB/RIF rose from 56.5% in 2017 to 64% in 2020 but fell to 60.9% in 2021. We found that older age (> 10 years), the presence of pulmonary TB (PTB), and a negative human immunodeficiency virus (HIV) status were associated with positive Xpert MTB/RIF tests (P = 0.002, 0.001, and 0.012, respectively). Conclusion: The utilization of Xpert MTB/RIF in children increased in the years before the COVID-19 pandemic. Factors associated with MTB detection by Xpert MTB/RIF include older age, the presence of PTB, and a negative HIV status. Clinical and radiological evaluation continues to play vital roles in the diagnosis of childhood TB in Nigeria.

Factors associated with common mental disorders among breastfeeding mothers in tertiary hospital nurseries in Nigeria.

BACKGROUND: Several studies have shown that the impact of maternal mental health disorders on newborns' well-being in low and middle-income countries (LMIC) are underreported, multi-dimensional and varies over time and differs from what is reported in high-income countries. We present the prevalence and risk factors associated with common mental disorders (CMDs) among breastfeeding mothers whose infants were admitted to Nigerian tertiary care facilities. METHODS: This was a national cross-sectional study involving mothers of hospitalised babies from eleven Nigerian tertiary hospitals. We used the WHO self-reporting Questionnaire 20 and an adapted WHO/UNICEF ten-step breastfeeding support package to assess mothers' mental health and breastfeeding support. RESULTS: Only 895 of the 1,120 mothers recruited from eleven tertiary healthcare nurseries in six geopolitical zones of Nigeria had complete datasets for analysis. The participants' mean age was 29.9 ± 6.2 years. One in four had CMDs; 24.0% (95% CI: 21.235, 26.937%). The ages of mothers, parity, gestational age at delivery, and length of hospital stay were comparable between mothers with and those without CMDs. Antenatal care at primary healthcare facilities (adjusted odds ratio [aOR:13], primary education [aOR:3.255] living in the south-southern region of the country [aOR 2.207], poor breastfeeding support [aOR:1.467], polygamous family settings [aOR:2.182], and a previous history of mental health disorders [aOR:4.684] were significantly associated with CMDs. In contrast, those from the middle and lower socioeconomic classes were less likely to develop CMDs, with [aOR:0.532] and [aOR:0.493], respectively. CONCLUSION: In Nigeria, the prevalence of CMDs is relatively high among breastfeeding mothers with infants admitted to a tertiary care facility. Prior history of mental illness, polygamous households, mothers living in the southern region and low or no educational attainment have a greater risk of developing CMDs. This study provides evidence for assessing and tailoring interventions to CMDs among breastfeeding mothers in neonatal nurseries in LMIC.

COVID-19 vaccine hesitancy in six geopolitical zones in Nigeria: a cross-sectional survey.

Introduction: the high expectations that heralded the development of COVID-19 vaccines has been plagued with vaccine hesitancy (VH). The prevalence and associated factors of COVID-19 VH in the six geopolitical zones in Nigeria are explored. Methods: using a cross sectional survey, a pre-tested and validated questionnaire on a "Google form" was distributed via social media platforms and hard copies in the six geopolitical zones of Nigeria. Included, using a chain-reference sampling technique, were healthcare workers (HCW), university students and adults in the general population. Participants who expressed unwillingness to receive COVID-19 vaccine in the event of an available vaccine were considered to have vaccine hesitancy. Frequency and percentage were used to describe categorical variables. Multivariable logistic regression analysis was used to assess for factors associated with VH. Level of significance was set at 5% on two-sided tails test. Results: among 1615 respondents, mean (standard deviation) age was 36.7 (11.3) years, and 847 (52.4%) were males. More than half were healthcare workers (943; 58.4%), 97.4% had at least secondary level of education, and majority 60.5% belonged to the upper social class. The prevalence of VH was 68.5% (1107/1615), and 67.2% preferred foreign manufactured COVID-19 vaccines. On multivariable regression analysis, residence in Northeast (AOR 6.01, 95% CI 2.24, 16.10) and Northwest (AOR 3.33, 95% CI 1, 48, 7.48) geopolitical zones, the Igbo ethnic group (AOR 1.88, 95% 1.10, 3.22), Christians (AOR 1.86, 95% 1.10, 3.14), nurses (AOR 3.50, 95% CI 1.25, 9.80), pharmacist (AOR 5.82, 95% CI 2.12, 16.32) and participants without confidence in foreign vaccines (AOR 4.13, 95% CI 2.99, 5.72) were at higher likelihood of VH. Conclusion: vaccine hesitancy is high among adults in Nigeria, with higher likelihood among the Igbo ethnic group, Christian faith, residence in Northeast and Northwest geopolitical zones and those with an aversion to foreign-made vaccines. Targeted interventions are required for the desired COVID-19 vaccine uptake rate and herd immunity.
