Background: The objective of the current study was to estimate the prevalence and associated factors of overweight/obesity among Bangladeshi adolescents aged 15-19 y and to identify whether wealth-related inequality exists for overweight/obesity among Bangladeshi older adolescents.

Methods: We analyzed publicly available national representative secondary data from the 2019-2020 Bangladesh Adolescent Health and Wellbeing Survey. This cross-sectional survey was carried out among 18 249 adolescents aged 15-19 y regardless of their marital status using a two-stage stratified sampling technique (the data of 9128 eligible adolescents were included in this analysis). The WHO reference population for body mass index-for-age (1+Z score) was considered as overweight/obesity.

Results: We found that girls had significantly (p<0.05) higher prevalence of overweight/obesity (11.63%) than boys (8.25%); however, their biological sex as well their age were not significantly associated with higher odds of overweight/obesity. Those who were in their higher grade (grade 11 and higher) in the school and had been exposed to media were more likely (1.67 and 1.39 times, respectively) to be overweight/obesity compared with primary grade (0-5) and those who experienced no media exposure, respectively. Inequality analysis revealed that adolescents belonging to wealthy households had significantly higher rates of overweight/obesity than those in poorer households (concentration index=0.093).

Conclusions: The study exhibited the multifaceted nature of overweight/obesity among Bangladeshi older teenagers, revealing that their school grade, exposure to media content and wealth-related inequality emerged as significant contributing factors. The findings underscore the urgent need for targeted interventions and public health strategies to address the escalating burden of overweight and obesity in this age group.

People living with HIV may move between health facilities: this is called 'transfer', and includes up- and down-referral based on clinical condition and lateral transfer (e.g. between primary healthcare [PHC] facilities for reasons such as geographic mobility or stigma). Transfers involving PHC facilities occur frequently and are associated with viraemia and disengagement. We reviewed the South African National Department of Health (NDOH) and Southern African HIV Clinicians Society websites and contacted NDOH officials to identify national guidelines applicable to HIV care in South Africa for recommendations on transfers involving PHC facilities. In total, 21/24 (88%) documents mentioned transfer, using the terms 'referral', 'linkage', 'transfer', 'transition' and 'handover'. Guidelines defined 'linkage to care' as connecting individuals to care after HIV testing, but other terms were not well defined. Documents emphasised transfers between different levels of the health system, and transfers between PHC facilities received limited attention. The transfer process was delineated for linkage to care, up- and down-referrals, but not for transfers between PHC facilities. Clinical management of patients transferring between PHC facilities and tracing of patients who requested transfers and missed their visits were not specified. Overall, transfers between PHC facilities were not well addressed and require attention to improve HIV treatment outcomes.

Background: The objective of the current study was to estimate the self-reported individual-level crude prevalence and cluster-level adjusted prevalence of TB for the districts of Tamil Nadu and to understand the spatial distribution of TB cases through spatial autocorrelation and hotspot analysis.

Methods: National Family Health Survey (NFHS) data, gathered during 2014-2015 (NFHS-4) and 2019-2021 (NFHS-5), were used in the current study to estimate district-wise, individual-level crude and cluster-level adjusted TB prevalence per 100 000 population in Tamil Nadu. This was illustrated with the help of spatial geographic representation for various districts of Tamil Nadu using SPSS and QGIS software. The spatial autocorrelation and hotspot analysis were performed using Geoda software.

Results: The overall self-reported individual-level crude prevalence of TB was 337 (95% CI 302 to 375) and 169 (95% CI 144 to 197) per 100 000 population, whereas the cluster-level adjusted prevalence of TB was 356 (95% CI 311 to 405) and 184 (95% CI 154 to 219) per 100 000 population in NFHS-4 and NFHS-5, respectively.

Conclusions: This study highlights those geographical areas with high rates of TB prevalence. This information would be useful for the state and district programme managers to identify areas of high TB prevalence where interventions can be focused.

Background: Commercial single-use endoscopic multiband ligators, used for esophageal variceal band ligation (EVL), are prohibitively expensive. To enable greater access to EVL, we used disruptive innovation to develop a novel endoscopic multiband ligator.

Methods: We designed and tested a prototype handle 'ENDOhandle' using computer-aided design modeling and exported a cap, trigger cord and latex to form a functional banding unit.

Results: The cost of the banding unit was US$4.80 compared with several hundred US dollars for commercially available devices in the USA.

Conclusions: Disruptive innovation technology developed an inexpensive ligator for resource-challenged health settings.

Background: Addressing the unmet need for family planning to prevent unintended pregnancies is a high priority for women's health, and training as an element of the symptothermal method (STM) is deemed to be an effective strategy. This study assessed training on knowledge, attitudes and satisfaction with STM to ameliorate the unmet need for family planning.

Methods: The study adopted a pre-post study design. A total of 136 women participated in this study. Knowledge and attitudes were assessed pre- and post-training as well as the level of satisfaction, using cycle charts and questionnaires. The χ2 test (p<0.05) was used to analyse data on sociodemographics, attitudinal characteristics and satisfaction. Paired samples t-test (p<0.05) was used to establish the mean difference of the two groups (knowledge and attitudes pre- and post-training).

Results: The paired samples t-test established that women have significant (t=-058.716, p=0.001) knowledge post-training (1.0000±0.00000) compared with pre-training (0.0682±0.01587) on STM. There was no significant (t=-1.419, p=0.158) difference in attitudes towards STM pre- and post-training. There was a significant level of satisfaction (p=0.001).

Conclusions: Our interventional study has enabled women to acquire robust knowledge, positive attitudes and satisfaction with the utilization of STM. This has ameliorated unmet need for family planning among participants.

When the coronavirus case was originally reported in Wuhan, China, in December 2019, it quickly spread throughout the world and became a global public health problem. Evidence of the admission and outcomes of coronavirus disease among patients with chronic obstructive pulmonary disease (COPD) has not been reported in Africa. Consequently, this research protocol uses a systematic review and meta-analysis of the admission and outcomes of COVID-19 in patients with COPD in Africa. All observational studies published in the English language and reporting on the prevalence, admission and outcomes of COVID-19 among patients with COPD in Africa will be included. A search strategy will be implemented using electronic databases and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol recommendations. The findings of this review will be reported to health program designers, decision-makers and healthcare providers.

Background: Evidence of time to culture conversion is used to predict the time of cure from the disease and the overall drug-resistant tuberculosis (TB) treatment duration. Even though evidence about sputum culture conversion is enormous in TB treatment, no study has yet been done in our areas, where cases are common. The study aimed to assess the time to sputum conversion and its predictors among drug-resistant TB patients from October 2013 to September 2021 in eastern Ethiopia.

Methodology: A retrospective cohort study was conducted in eastern Ethiopia among 273 drug-resistant TB patients who were treated from October 2013 to September 2021 at Dire Dawa City and Harari regional treatment centres. The Kaplan-Meier method was used to estimate the median time of sputum culture conversion. Cox proportional hazards regression was employed to detect the predictors of sputum culture conversion. An adjusted hazard ratio (aHR) with 95% confidence interval (CI) was used to determine the strength and significance of the association.

Results: Of the 273 drug-resistant TB patients, the sputum culture of 216 (79.12%) patients became negative in a median time of 3 months (interquartile range 2-7). The time to sputum culture conversion was negatively associated with underweight (aHR 0.65 [95% CI 0.49 to 0.90]) and poor adherence (aHR 0.41 [95% CI 0.24 to 0.69]). The time to sputum culture conversion was also positively associated with patients resistant to two or more drugs (aHR 1.58 [95% CI 1.07 to 2.32]) and patients receiving a short treatment regimen (aHR 2.24 [95% CI 1.10 to 2.55]).

Conclusions: A shorter culture conversion rate was observed compared with the median time recommended by the World Health Organization. Being underweight, poor adherence to treatment, resistance to two or more drugs and receiving a short treatment regimen were found to be predictors of time to sputum culture conversion. Implementing nutrition assessment, counselling and support of drug adherence may improve sputum culture conversion.

Background: Neurodevelopmental disorders are a set of disorders that negatively affect the acquisition of skills in a variety of developmental domains, including motor function, learning, socialization, language and cognition. However, there is no information available on the standard of living of Ethiopian primary caregivers of children and adolescents with neurodevelopmental disorders. Therefore, this study aimed to assess the quality of life (QOL) and associated factors among primary caregivers of children and adolescents with neurodevelopmental disorders in Addis Ababa, Ethiopia.

Methods: A cross-sectional study was conducted during 1-30 May 2022. Systematic random sampling was used to obtain 352 samples. QOL was measured using the WHO Quality of Life Brief. The gathered information was coded, entered into EpiData 4.6.0.2 and analyzed with SPSS version 26. Multiple linear regression analysis was used to identify the correlates of QOL and the strength of the correlation was measured by β coefficient with 95% CI.

Results: The mean score of the overall QOL was 62.61 with a SD of 5.17. The mean (±SD) scores for the physical health, psychological, environmental and social relationship domains of primary caregivers were 57.36±9.98, 66.98±9.39, 66.06±12.91 and 60.02±9.14, respectively. Age was significantly associated with physical domain (β=-0.25, 95% CI -0.43 to -0.07) and with environmental domain (β=-4.57, 95% CI -9.06 to -0.09). Being divorced/widowed was negatively associated with psychological health (β=-2.99, 95% CI -5.82 to -0.17) and social health (β=-0.62, 95% CI -1.33 to -0.10). The presence of medical illness was negatively associated with the physical health domain (β=-4.32, 95% CI -7.64 to -2.91) and the environmental domain (β=-3.11, 95% CI -5.71 to -0.51). Poor social support was negatively associated with psychological health (β=-3.25, 95% CI -5.89 to -0.61) and the social health domain (β=-3.39, 95% CI -11.3 to 4.6), and moderate social support (β=8.62, 95% CI 3.15 to 14.09) was positively associated with physical health. Depression (β=-6.32, 95% CI -11.96 to -0.67) and anxiety (β =-3.07, 95% CI -5.80 to -0.34) were negatively associated with physical health and the psychological health domain, respectively.

Conclusions: The findings from this study indicate that all dimensions of QOL of primary caregivers of children and adolescents with neurodevelopmental disorders in this study setting were compromised. Being divorced or widowed, lack of formal education, age, average monthly income, poor social support, depression, anxiety and the presence of medical illness were factors associated with QOL in all domains. This requires integrating a bio-psychosocial perspective, a positive mental health strategy and pharmaceutical therapies to enhance QOL for caregivers of children and adolescents with neurodevelopmental disorders.
