The coronavirus disease 2019 pandemic emphasised the importance of laboratory preparedness, including molecular diagnostic capacity, in the control of infectious disease outbreaks. This article reflects on diagnostic capacity-building opportunities presented by the pandemic, the challenges experienced along the way and the lessons learned from the perspective of a university teaching hospital in Southern Nigeria. We advocate for these lessons to inform strategic planning for laboratory preparedness at subnational, national and continental levels.

Giardia duodenalis is one of the major causes of diarrhea among children. We performed a systematic review and meta-analysis to assess the prevalence of G. duodenalis and associated risk factors among Asian children. We searched online databases (PubMed, Scopus and Web of Science) and Google Scholar search engine for studies published from 1 January 2000 to 15 March 2022 that measured the prevalence of G. duodenalis among Asian children. Accordingly, the pooled prevalence and 95% CIs were estimated using a random-effects meta-analysis model for the included studies. A total of 182 articles from 22 Asian countries met the inclusion criteria. The pooled prevalence of G. duodenalis infection among Asian children was estimated as 15.1% (95% CI 14.1 to 16%). The highest and lowest pooled prevalence values of G. duodenalis infection were estimated for Tajikistan and China as 26.4% (95% CI 22.9 to 30%) and 0.6% (95% CI 0.001 to 1.02%), respectively. The infection had a higher prevalence in males than in females (OR=1.24; 95% CI 1.16 to 1.31; p<0.001), which was statistically significant. Giardiasis is common among Asian children, hence, a prevention and control scheme of this protozoan in children should be considered by health officials and health policymakers, especially in Asian countries where the prevalence is highest.

There have been few reports from Africa on the use and health effects of emollient therapy for newborn infants. We aimed to describe neonatal skin care practices in Africa, and to illuminate opportunities to introduce evidence-based interventions to improve these practices. We conducted a scoping review of the quantitative and qualitative published peer-reviewed and grey literature in English on emollient use in Africa. Outcomes of interest included neonatal skin care practices, with a focus on the application of oils and other products to infant skin, including in association with bathing and massage. We screened 5257 articles and summarised findings from 23 studies-13 qualitative, nine quantitative and one mixed methods-that met our study criteria. Seven studies reported the use of emollients for perceived benefits, including thermal care, treatment for illness, promotion of growth and development, infection reduction, skin condition improvement, spirituality and lubrication to aid massage. Four studies reported the quantitative health impact of skin care product applications, including improvements in skin condition, neurodevelopment and bone growth, as well as a reduction in nosocomial infections. This review highlights opportunities for skin care intervention and future research on neonatal skin care practices in Africa.

Background: Quality and adequate antenatal care (ANC) are key strategies necessary to achieve Sustainable Development Goal 3.1. However, in sub-Saharan Africa (SSA), there is a paucity of evidence on the role women's empowerment and socio-economic status play in ANC attendance. This study aimed to examine whether women's empowerment and socio-economic status predict the adequacy of ANC in SSA.

Methods: Data from the recent Demographic and Health Surveys (DHSs) of 10 countries in SSA were used for the study. We included countries with a survey dataset compiled between 2018 and 2020. We included 57 265 women with complete observations on variables of interest in the study. Frequencies and percentages were used to summarize the results of the coverage of adequate ANC services across the 10 countries. A multivariable binary multilevel regression analysis was employed to examine the association between women's empowerment and socio-economic status indicators and the adequacy of ANC. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were used to present the findings of the regression analysis.

Results: The average prevalence of adequate ANC in SSA was 10.4%. This ranged from 0.2% in Rwanda to 24.5% in Liberia. Women with medium (aOR 1.24 [CI 1.10 to 1.40]) and high (aOR 1.24 [CI 1.07 to 1.43]) decision-making power had higher odds of adequate ANC compared to those with low decision-making power. Women with higher levels of education (aOR 1.63 [CI 1.36 to 1.95]) as well as partners with higher education levels (aOR 1.34 [CI 1.14 to 1.56]) had the highest odds of adequate ANC compared to those with no formal education. Additionally, those working (aOR 1.35 [95% CI 1.23 to 1.49]) and those in the richest wealth category (aOR 2.29 [CI 1.90 to 2.76]) had higher odds of adequate ANC compared to those who are not working and those in the poorest wealth category. Those with high justification of violence against women (aOR 0.84 [CI 0.73 to 0.97]) had lower odds of adequate ANC compared to those with low justification of violence against women.

Conclusions: Adequacy of ANC was low across all 10 countries we included in this study. It is evident from the study that women's empowerment and socio-economic status significantly predicted the adequacy of ANC. As such, promoting women's empowerment programs without intensive improvements in women's socio-economic status would yield ineffective results. However, when women's empowerment programs are combined with active improvements in socio-economic status, then women will be encouraged to seek adequate ANC.

Background: Low medication adherence among patients with type 2 diabetes mellitus (T2DM) is associated with significant morbidity and mortality globally. We investigated the prevalence of low medication adherence and its associated factors among patients with T2DM.

Methods: We used the Bengali version of the 8-item Morisky Medication Adherence Scale (MMAS-8) in measuring medication adherence among patients with T2DM who were attending the diabetes clinic at Amana Regional Referral Hospital in Dar es Salaam, Tanzania, from December 2021 to May 2022. Binary logistic regression analysis under multivariate analysis was used to determine the predictors of low medication adherence after controlling for confounders. A two-tailed p-value <0.05 was considered significant.

Results: The prevalence of low medication adherence was 36.7% (91/248) of the subjects included in the study. Lack of formal education (adjusted odds ratio [AOR] 5.3 [95% confidence interval {CI} 1.717 to 16.312], p=0.004), having comorbidities (AOR 2.1 [95% CI 1.134 to 3.949], p=0.019) and drinking alcohol (AOR 3.5 [95% CI 1.603 to 7.650], p=0.031) were the independent predictors of low medication adherence.

Conclusion: More than one-third of the patients with T2DM in this study had low medication adherence. Our study also showed that a lack of formal education, having comorbidities and drinking alcohol were significantly associated with low medication adherence.

Background: By 1987, onchocerciasis in Niger had been successfully controlled in the six endemic river basins. In 2017, onchocerciasis elimination mapping (OEM) was carried out to determine if there was any ongoing transmission in the country as a whole.

Methods: The recommended OEM procedures were implemented.

Results: Ten districts, that included 35 villages, required field investigation as sites of possible transmission. None of these were found capable of supporting black fly breeding, nor was there any evidence of the presence of Simulium sp. flies.

Conclusions: The implementation of OEM indicates that there is no transmission of onchocerciasis currently taking place in these newly assessed sites in Niger.

Background: The desire to have children among mothers living with HIV remains a serious public health issue in nations with low coverage for antiretroviral therapy and the prevention of mother-to-child transmission, even if it is feasible to have an HIV-negative child. Therefore, this study aimed to assess fertility desire and associated factors among antiretroviral therapy-attending HIV-positive women at Hiwot Fana Specialized University Hospital, in Harari, Ethiopia.

Methods: A facility-based cross-sectional study design was employed among 639 anti retro-viral therapy attending HIV - positive women by systematic random sampling method selected from June 15 to November 30, 2020. A binary logistic regression model was fitted to identify the associated factors with fertility desire. Descriptive results were presented in percentages, whereas analytical results were reported in adjusted ORs (AORs) with a 95% CI. At p=0.05, statistical significance was declared.

Results: A total of 639 participants were included in the study; 69.5%(95% CI 65.7 to 72.9%) of the participants had fertility desire. Younger age (<35 years) (AOR=2.35, 95% CI 1.27 to 4.35), married women (AOR=3.02, 95% CI 1.32 to 12.25), childless women (AOR=2.86, 95% CI 1.17 to 4.82) and women whose duration of HIV diagnosis was ≤5 years (AOR=0.41, 95% CI 0.20 to 0.71) were significantly associated with fertility desire.

Conclusion: The majority of the study participants have a desire to have children. In light of the high prevalence of fertility desire among antiretroviral therapy-attending HIV-positive women, it is recommended to counsel younger women on reproductive planning and encourage partner testing.

Background: Post-exposure prophylaxis (PEP) is an effective tool to prevent infection with HIV. Patients seeking PEP after potential HIV exposure usually present to the emergency department (ED). Our study sought to determine the concordance of ED physicians' decisions on HIV-PEP with national guidelines (primary objective) and to assess the clinical relevance of drug-drug interactions (DDIs) between the HIV-PEP regimen and patients' concomitant medication (secondary objective).

Methods: We conducted a retrospective cohort study at the ED of Hannover Medical School, Germany. Between 1 January 2018 and 31 December 2019, 113 of 11 246 screened patients presented to the ED after potential HIV exposure and were enrolled in the study.

Results: The median age of the patients (82.3% male) was 30 y (IQR 25-35.5), 85.8% of potential HIV exposures were characterised as sexual and 85.0% presented within 72 h. ED physicians' decisions on HIV-PEP were concordant with national guidelines in 93.8%. No clinically relevant DDIs were detected.

Conclusions: ED physicians' decisions on HIV-PEP were highly concordant with national guidelines. Approximately 1% of patient presentations to the ED were related to HIV exposure; therefore, training ED physicians on HIV transmission risk assessment and indications/contraindications for HIV-PEP is paramount.

Background: This study aimed to assess the long-term effects of size-specific particulate matter (PM) on frailty transitions in middle-aged and older Chinese adults.

Methods: We included 13 910 participants ≥45 y of age from the China Health and Retirement Longitudinal Study (CHARLS) for 2015 and 2018 who were classified into three categories in 2015 according to their frailty states: robust, prefrail and frail. Air quality data were obtained from the National Urban Air Quality Real-time Publishing Platform. A two-level logistic regression model was used to examine the association between concentrations of PM and frailty transitions.

Results: At baseline, the total number of robust, prefrail and frail participants were 7516 (54.0%), 4324 (31.1%) and 2070 (14.9%), respectively. Significant associations were found between PM concentrations and frailty transitions. For each 10 μg/m3 increase in the 3-y averaged 2.5-μm PM (PM2.5) concentrations, the risk of worsening in frailty increased in robust (odds ratio [OR] 1.06 [95% confidence interval {CI} 1.01 to 1.12]) and prefrail (OR 1.07 [95% CI 1.01 to 1.13]) participants, while the probability of improvement in frailty in prefrail (OR 0.91 [95% CI 0.84 to 0.98]) participants decreased. In addition, the associations of PM10 and coarse fraction of PM with frailty transitions showed similar patterns.

Conclusions: Long-term exposure to PM was associated with higher risks of worsening and lower risks of improvement in frailty among middle-aged and older adults in China.

Background: In integrated community case management (iCCM) care, community health workers (CHWs) provide home-based management of fever, diarrhea and fast breathing for children aged <5 y. The iCCM protocol recommends that children with danger signs for severe illness are referred by CHWs to health facilities within their catchment area. This study examines the management of danger signs by CHWs implementing iCCM in a rural context.

Methods: A retrospective observational study that examined clinical records for all patients with danger signs evaluated by CHWs from March 2014 to December 2018 was conducted.

Results: In total, 229 children aged <5 y had been recorded as having a danger sign during 2014-2018. Of these children, 56% were males with a mean age of 25 (SD 16.9) mo, among whom 78% were referred by the CHWs as per the iCCM protocol. The age category of 12 to 35 mo had the highest numbers of prereferred and referred cases (54% and 46%, respectively).

Conclusions: CHWs play a key role in early symptomatic detection, prereferral treatment and early referral of children aged <5 y. Danger signs among children aged <5 y, if left untreated, can result in death. A high proportion of the children with danger signs were referred as per the iCCM protocol. Continuous CHW training is emphasized to reduce the number of referral cases that are missed. More studies need to focus on children aged 12-35 mo and why they are the most referred category. Policymakers should occasionally revise iCCM guidelines to detail the types of danger signs and how CHWs can address these.
