Effectiveness of lifestyle interventions for glycaemic control among adults with type 2 diabetes in West Africa: a systematic review and meta-analysis protocol.

BACKGROUND: Lifestyle interventions are key to the control of diabetes and the prevention of complications, especially when used with pharmacological interventions. This protocol aims to review the effectiveness of lifestyle interventions in relation to nutrition and physical activity within the West African region. This systematic review and meta-analysis seeks to understand which interventions for lifestyle modification are implemented for the control of diabetes in West Africa at the individual and community level, what evidence is available on their effectiveness in improving glycaemic control and why these interventions were effective. METHODS: We will review randomised control trials and quasi-experimental designs on interventions relating to physical activity and nutrition in West Africa. Language will be restricted to English and French as these are the most widely spoken languages in the region. No other filters will be applied. Searching will involve four electronic databases - PubMed, Scopus, Africa Journals Online and Cairn.info using natural-language phrases plus reference/citation checking. Two reviewers will independently screen results according to titles and abstracts against the inclusion and exclusion criteria to identify eligible studies. Upon full-text review, all selected studies will be assessed using Cochrane's Collaboration tool for assessing the risk of bias of a study and the ROBINS-I tool before data extraction. Evidence will be synthesised narratively and statistically where appropriate. We will conduct a meta-analysis when the interventions and contexts are similar enough for pooling and compare the treatment effects of the interventions in rural to urban settings and short term to long term wherever possible. DISCUSSION: We anticipate finding a number of studies missed by previous reviews and providing evidence of the effectiveness of different nutrition and physical activity interventions within the context of West Africa. This knowledge will support practitioners and policymakers in the design of interventions that are fit for context and purpose within the West African region. SYSTEMATIC REVIEW REGISTRATION: This systematic review has been registered in the International Prospective Register for Systematic Reviews - PROSPERO, with registration number CRD42023435116. All amendments to this protocol during the process of the review will be explained accordingly.

A comparative systematic review of risk factors, prevalence, and challenges contributing to non-communicable diseases in South Asia, Africa, and Caribbeans.

BACKGROUND: Non-communicable diseases (NCDs) are a global epidemic challenging global public health authorities while imposing a heavy burden on healthcare systems and economies. AIM: To explore and compare the prevalence of NCDs in South Asia, the Caribbean, and non-sub-Saharan Africa, aiming to identify both commonalities and differences contributing to the NCD epidemic in these areas while investigating potential recommendations addressing the NCD epidemic. METHOD: A comprehensive search of relevant literature was carried out to identify and appraise published articles systematically using the Cochrane Library, Ovid, Google Scholar, PubMed, Science Direct, and Web of Science search engines between 2010 and 2023. A total of 50 articles fell within the inclusion criteria. RESULTS: Numerous geographical variables, such as lifestyle factors, socio-economic issues, social awareness, and the calibre of the local healthcare system, influence both the prevalence and treatment of NCDs. The NCDs contributors in the Caribbean include physical inactivity, poor fruit and vegetable intake, a sedentary lifestyle, and smoking, among others. While for South Asia, these were: insufficient societal awareness of NCDs, poverty, urbanization, industrialization, and inadequate regulation implementation in South Asia. Malnutrition, inactivity, alcohol misuse, lack of medical care, and low budgets are responsible for increasing NCD cases in Africa. CONCLUSION: Premature mortality from NCDs can be avoided using efficient treatments that reduce risk factor exposure for individuals and populations. Proper planning, implementation, monitoring, training, and research on risk factors and challenges of NCDs would significantly combat the situation in these regions.

Comparison of the prevalence and associated factors of chronic kidney disease diagnosed by serum creatinine or cystatin C among young people living with HIV in Uganda.

Introduction: Young people living with HIV (YPLHIV) are at increased risk of developing chronic kidney disease (CKD) which is associated with high mortality and morbidity. Early diagnosis is important to halt progression. We aimed to estimate the prevalence and factors associated with CKD among YPLHIV in Kampala, Uganda, and to compare serum creatinine and cystatin C for early diagnosis of CKD in this population. Methods: A cross-sectional study with YPLHIV aged 10 to 24 years was conducted in seven HIV clinics. Participants provided a urine and blood sample to measure urinary albumin, proteinuria, serum creatinine and cystatin C levels at baseline and after three months. The estimated glomerular filtration rate (eGFR) was calculated using CKDEPI 2021, Cockroft-Gault and bedside Schwartz equations using creatinine or cystatin C. The albumin creatinine ratio (ACR) and proteinuria were measured. CKD was defined as either eGFR <60ml/min/1.73m2 or <90ml/min/1.73m2 or ACR above 30mg/g on two separate occasions. Univariable and multivariable logistic regression were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for factors associated with CKD. Results: A total of 500 participants were enrolled. Most were female (56%; n=280) and aged 10 to 17 years (66.9%; n=335). CKD prevalence ranged from 0-23% depending on the criteria, equation and biomarker used. Cystatin C-based equations estimated higher prevalence of CKD compared to creatinine-based ones. Prevalence of ACR above 30mg/g was 10.1% and of proteinuria 29%. Factors independently associated with CKD were age (aOR=1.42; 95% CI:1.30-1.51) and male sex (aOR=3.02; 95% CI:1.68-5.43). Conclusion: CKD prevalence among YPLHIV varied substantially depending on definitions used and the current definition would likely lead to missed cases of CKD among YPLHIV. Estimating equations should be validated against measured GFR in YPLHIV and the optimal definition of CKD in this vulnerable population should be revised to optimise detection and opportunities for reducing disease progression.

The financial burden of noncommunicable diseases from out-of-pocket expenditure in sub-Saharan Africa: a scoping review.

The growing financial burden of noncommunicable diseases (NCDs) in sub-Saharan Africa (SSA) hinders the attainment of the sustainable development goals. However, there has been no updated synthesis of evidence in this regard. Therefore, our study summarizes the current evidence in the literature and identifies the gaps. We systematically search relevant databases (PubMed, Scopus, ProQuest) between 2015 and 2023, focusing on empirical studies on NCDs and their financial burden indicators, namely, catastrophic health expenditure (CHE), impoverishment, coping strategies, crowding-out effects and unmet needs for financial reasons (UNFRs) in SSA. We examined the distribution of the indicators, their magnitudes, methodological approaches and the depth of analysis. The 71 included studies mostly came from single-country (n = 64), facility-based (n = 52) research in low-income (n = 22), lower-middle-income (n = 47) and upper-middle-income (n = 10) countries in SSA. Approximately 50% of the countries lacked studies (n = 25), with 46% coming from West Africa. Cancer, cardiovascular disease (CVD) and diabetes were the most commonly studied NCDs, with cancer and CVD causing the most financial burden. The review revealed methodological deficiencies related to lack of depth, equity analysis and robustness. CHE was high (up to 95.2%) in lower-middle-income countries but low in low-income and upper-middle-income countries. UNFR was almost 100% in both low-income and lower-middle-income countries. The use of extreme coping strategies was most common in low-income countries. There are no studies on crowding-out effect and pandemic-related UNFR. This study underscores the importance of expanded research that refines the methodological estimation of the financial burden of NCDs in SSA for equity implications and policy recommendations.

Explainable artificial intelligence models for predicting pregnancy termination among reproductive-aged women in six east African countries: machine learning approach.

Pregnancy termination remains a complex and sensitive issue with approximately 45% of abortions worldwide being unsafe, and 97% of abortions occurring in developing countries. Unsafe pregnancy terminations have implications for women's reproductive health. This research aims to compare black box models in their prediction of pregnancy termination among reproductive-aged women and identify factors associated with pregnancy termination using explainable artificial intelligence (XAI) methods. We used comprehensive secondary data on reproductive-aged women's demographic and socioeconomic data from the Demographic Health Survey (DHS) from six countries in East Africa in the analysis. This study implemented five black box ML models, Bagging classifier, Random Forest, Extreme Gradient Boosting (XGB) Classifier, CatBoost Classifier, and Extra Trees Classifier on a dataset with 338,904 instances and 18 features. Additionally, SHAP, Eli5, and LIME XAI techniques were used to determine features associated with pregnancy termination and Statistical analysis were employed to understand the distribution of pregnancy termination. The results demonstrated that machine learning algorithms were able to predict pregnancy termination on DHS data with an overall accuracy ranging from 79.4 to 85.6%. The ML classifier random forest achieved the highest result, with an accuracy of 85.6%. Based on the results of the XAI tool, the most contributing factors for pregnancy termination are wealth index, current working experience, and source of drinking water, sex of household, education level, and marital status. The outcomes of this study using random forest is expected to significantly contribute to the field of reproductive healthcare in East Africa and can assist healthcare providers in identifying individuals' countries at greater risk of pregnancy termination, allowing for targeted interventions and support.

Predominant approaches to measuring pregnancy-related anxiety in Sub-saharan Africa: a scoping review.

BACKGROUND: Pregnancy-related anxiety significantly impacts maternal and fetal health in low- and middle-income countries (LMICs), including those within Sub-Saharan Africa (SSA). Most studies conducted to evaluate pregnancy-related anxiety in LMICs have utilized scales developed in high-income countries, despite significant variations in pregnancy-related anxiety due to socioeconomic and cultural contexts. This review surveyed existing literature in order to identify which scales have been used to measure pregnancy-related anxiety in SSA. METHODS: A systematic search was conducted in PubMed, Health and Psychosocial Instruments, and APA PsycNet for relevant studies published in the English language up to March 22, 2023. Eligible studies focused on anxiety in pregnant populations within SSA, using validated scales or tools. Screening followed PRIMSA guidelines, with blinded review at the abstract/title level and subsequent full-text review. Data was extracted and analyzed to identify trends and characteristics of the screening tools used. RESULTS: From 271 articles, 37 met inclusion criteria, identifying 24 different tools used to measure anxiety in pregnant women in SSA. The most common tools were the Generalized Anxiety Disorder 7-item scale (seven uses), State-Trait Anxiety Inventory (five uses), and the Self-Reporting Questionnaire 20 (five uses). Seven tools were pregnancy-specific, with only two designed specifically for SSA: the Risk Factor Assessment (RFA), and the 4-Item Screening Tool. Studies were most frequently conducted in South Africa, followed by Tanzania, Ethiopia, Nigeria, and Ghana. CONCLUSIONS: This scoping review illustrates that only two tools (the RFA and 4-item Screening Tool) were created to assess pregnancy-related anxiety specifically in SSA. This highlights the need for more culturally sensitive tools tailored to the specific contexts of pregnant populations in SSA.

Fetal malnutrition among neonates in African countries: a CAN score systematic review and meta-analysis.

BACKGROUND: To reduce neonatal mortality, it is necessary to identify neonates with fetal malnutrition at birth using the clinical assessment score (CAN score). Furthermore, comprehensive summary data that shows burden of fetal malnutrition in Africa is scarce. As a result, this systematic review and meta-analysis aimed to assess fetal malnutrition among newborns in Africa. METHOD: The PRISMA guidelines were used for this study. Articles were obtained from databases and websites. The outcome of the study was fetal malnutrition, as determined using the CAN score. The meta-analysis of the primary and secondary outcomes was performed using Stata version 18 statistical software. The pooled prevalence with a 95% CI was estimated using the random effect method with the Der Simonian Liard model. RESULTS: This meta-analysis and systematic review included 5356 newborns from 13 studies. The pooled prevalence of fetal malnutrition (FM) among newborns diagnosed using the CAN score in Africa was 19% [95% CI: 17, 22]. Based on subgroup analysis by publication year, the lowest prevalence of fetal malnutrition 17% (95% CI: 9-27) was observed in the studies published in the years 2020-2023. Maternal and fetal factors were significantly associated with fetal malnutrition. CONCLUSION: Nearly one-fifth of neonates delivered in Africa were found to have fetal malnutrition based on the clinical evaluation of nutritional status. It has also been established that maternal malnutrition, a lack of proper treatment during pregnancy, maternal malnutrition, and newborn morbidities were associated with fetal malnutrition. To prevent fetal malnutrition, integrated efforts should be made for early maternal infection screening. Furthermore, maternal nutritional therapy should be explored for malnourished pregnant women.

An optimized strategy triggered at the 2nd immunization visit to prevent HIV acquisition by breastfeeding: a phase 2 trial in Burkina Faso (PREVENIR-PEV).

BACKGROUND: Mother-to-child transmission of HIV during breastfeeding remains a challenge in low- and middle-income countries (LMIC). A prevention package was initiated during the highly attended 2nd visit of the Expanded Program of Immunisation (EPI-2) to identify the undiagnosed infants living with HIV and reduce the postnatal transmission of infant exposed to HIV. METHODS: PREVENIR-PEV is a non-randomized phase II clinical trial conducted at two health centres in Bobo Dioulasso (Burkina Faso). The study recruited mothers living with HIV aged 15 years and older with their singleton breastfed infants. During EPI-2 (at 8 weeks) and upon signature of the informed consent, a point-of-care early infant diagnosis (EID) was performed. HIV exposed uninfected (HEU) infants were followed-up until 12 months of age. High risk HEU infants (i.e., whose maternal viral load ≥ 1000 cp/mL at EPI-2 or M6) received an extended postnatal prophylaxis (PNP) with lamivudine until end of follow-up or the end of breastfeeding. RESULTS: Between 4 December 2019 and 4 December 2020, 118 mothers living with HIV-1 were identified, and 102 eligible mother/infant pairs had their infants tested for HIV EID. Six infants were newly diagnosed with HIV, and 96 HEU infants were followed-up for 10 months. Among the participants followed-up, all mothers were prescribed antiretrovirals. All 18 infants eligible for PNP at either EPI-2 or 6 months (M6) were initiated on lamivudine. No HIV transmission occurred, and no serious adverse events were reported in infants receiving lamivudine. CONCLUSIONS: The PREVENIR-PEV prevention package integrated into existing care is safe and its implementation is feasible in a LMIC with a low HIV prevalence. More research is needed to target mother/infant pairs not adhering to the intervention proposed in this trial. TRIAL REGISTRATION: NCT03869944; first registered on 11/03/2019.

Suspected poor-quality medicines in Kenya: a retrospective descriptive study of medicine quality-related complaints reports in Kenya's pharmacovigilance database.

Poor-quality, substandard and falsified, medicines pose a significant public health threat, particularly in low-middle-income countries. A retrospective study was performed on Kenya's Pharmacovigilance Electronic Reporting System (2014-2021) to characterize medicine quality-related complaints and identify associations using disproportionality analysis. A total of 2767 individual case safety reports were identified, categorized into medicines with quality defects (52.1%), suspected therapeutic failure (41.6%), and suspected adverse drug reactions (6.3%). Predominantly reported were antineoplastic agents (28.6%), antivirals (11.7%), and antibacterial agents (10.8%) potentially linked to non-adherence to good manufacturing practices, inappropriate usage and supply chain degradation. Notably, analgesics (8.2%), and medical devices (3.5%) notified had quality defects, predominantly from government health facilities (60.0%). Antineoplastic agents (20.2%) and antivirals (3.7%) were frequently reported from suspected therapeutic failures and suspected adverse drug reactions, respectively, across both private for-profit facilities (26.5%) and not-for-profit facilities (5.4%). Underreporting occurred in unlicensed health facilities (8.1%), due to unawareness and reporting challenges. Pharmacists (46.1%), and pharmaceutical technicians (11.7%) predominantly reported quality defects, while medical doctors (28.0%) reported suspected therapeutic failures. Orally administered generic medicines (76.9%) were commonly reported, with tablets (5.8%) identified as potential sources of suspected adverse drug reactions, while quality defects were notified from oral solutions, suspensions, and syrups (7.0%) and medical devices (3.9%). The COVID-19 pandemic correlated with reduced reporting possibly due to prioritization of health surveillance. This study provides valuable evidence to supporting the use of medicine quality-related complaints for proactive, targeted regulatory control of high-risk medicines on the market. This approach can be strengthened by employing standardized terminology to prioritize monitoring of commonly reported suspected poor-quality medicines for risk-based sampling and testing within the supply chain.

The electro-convulsive therapy story of Africa, a systematic review.

Over the years, the use of Electroconvulsive therapy (ECT) has gained increasing acceptance as a viable treatment for managing treatment-resistant mental health conditions, and it is known to deliver more rapid therapeutic benefits than most treatment modalities in psychiatry. However, the practice of ECT exhibits significant variability both within and between countries. This review aimed to shed light on the status of ECT in the African context and its implications for mental health care in the region. In July 2023, databases (Ovid, PubMed, Web of Science, etc.) were searched for articles about ECT in Africa, following the PRISMA guidelines. Eligible studies reporting ECT practices in Africa and those about knowledge, attitudes, and perceptions were excluded. A total of 25 articles met the study criteria. The reviewed studies revealed that unmodified ECT continues to be used in some African countries due to resource limitations, while bilateral ECT is widely practiced across the continent. The primary diagnostic indications for ECT in Africa included severe depression and affective disorders. ECT usage and regulation vary significantly throughout Africa. The studies, primarily observational, detailed numerous challenges in employing the method, particularly concerning resource utilization in healthcare facilities. The review highlights the necessity for adaptable standards and local protocols to enhance ECT practices throughout Africa. It emphasizes the importance of conducting more evidence-based research to develop region-specific guidelines that ensure the safe and effective use of ECT. Policymakers and healthcare practitioners should prioritize resource allocation, training, and standardization to improve ECT delivery and outcomes on the continent.

Incidence and risk factors for colorectal cancer in Africa: a systematic review and meta-analysis.

INTRODUCTION: Colorectal cancer (CRC) is the second leading cause of cancer-related death worldwide. There is a significant burden of mortality from colorectal cancer in Africa. Due to the heterogeneity of dietary and lifestyle practices throughout Africa, our work sought to define risk factors for the development of CRC in the African continent. METHODS: We systematically searched PubMed, Embase, Global Health, CINAHL, Cochrane CENTRAL, and African Index Medicus for studies written in English, examining the incidence and risk factors of CRC in Africa. A systematic analysis was done to compare different risk factors in constituent studies. A meta-analysis random effects model was fitted to estimate the pooled incidence of CRC. RESULTS: Of 2471 studies screened, 26 were included for the quantitative analysis; 20 in the incidence analysis, and six in the risk factor analysis. The overall ASIR per 100,000 person-years of CRC for males and females was 7.51 and 6.22, respectively. The highest incidence rates were observed between 2012 and 2021. Risk factors for CRC in Africa include tobacco smoking, and consumption of red meat, butter, and alcohol. Protective factors included, regular consumption of fruits and regular physical activity. CONCLUSION: The incidence of CRC in Africa is higher than that suggested by previous studies. Our study shows that nonmodifiable and modifiable factors contribute to CRC in Africa. High-quality studies conducted on generalizable populations that examine risk factors in a comprehensive fashion are required to inform primary and secondary prevention initiatives for CRC in Africa.

Unmasking the complexities of healthcare access in low-resource settings: a health systems approach to obstetric and under-5 healthcare in rural settings of Eastern Uganda.

BACKGROUND: Access to appropriate obstetric and under-5 healthcare services in low-resource settings is a challenge in countries with high mortality rates. However, the interplay of multiple factors within an ecological system affects the effectiveness of the health system in reaching those in need. OBJECTIVE: This study examined how multiple factors concurrently affect access to obstetric and child healthcare services in resource-poor settings. METHODS: The research used social autopsies [in-depth interview] with mothers who experienced newborn death [n = 29], focus group discussions [n = 8] with mothers [n = 32], and fathers [n = 28] of children aged 6-59 months, and the author's field observations in Eastern Uganda's rural settings. The research employed narrative and inductive thematic analysis, guided by concepts of social interactions, behaviour, and health institutional systems drawn from system theory. RESULTS: The study unmasked multiple concurrent barriers to healthcare access at distinct levels. Within families, the influence of mothers-in-law and gender dynamics constrains women's healthcare-seeking autonomy and agency. At the community level, poor transport system, characterised by long distances and challenging road conditions, consistently impede healthcare access. At the facility level, attitudes, responsiveness, and service delivery of health workers critically affect healthcare access. Negative experiences at health facilities profoundly discourage the community from seeking future health services. CONCLUSION: The findings emphasise the persistent influence of structural and social factors that, although well documented, are often overlooked and continue to limit women's agency and autonomy in healthcare access. Enhancing universal access to appropriate healthcare services requires comprehensive health systems interventions that concurrently address the healthcare access barriers.

Main findings: The findings highlight the persistent influence of structural and social factors that have been well documented yet often overlooked.Added knowledge: While the barriers to and essential components of an effective health system are well known, the current global health space requires an understanding of how the structural, cultural, and social nuances have persistently affected the marginalised communities.Global health impact for policy and action: For a transformative health system, promoting equitable and accessible appropriate healthcare for all necessitates a holistic approach that identifies and addresses healthcare access barriers.

Understanding HIV service preferences of South African women 30-49 years old missing from or linked to care: An exploratory study of Gauteng and Limpopo provinces.

BACKGROUND: The HIV epidemic in sub-Saharan Africa has a disproportionate gender impact, with women bearing the brunt of the epidemic. South Africa carries the largest share of the global HIV burden, with similar trends seen for women due to unequal socio-cultural and economic status. OBJECTIVES: This study aims to understand 30-49 year-old women's barriers and facilitators to accessing HIV services in order to maximize health in resource limited settings and reach women missing from HIV care. DESIGN: Employing a convenience sampling strategy, we recruited, informed, and consented participants at clinics and public areas. Interviews were conducted in respondent's preferred languages, transcribed verbatim, translated into English if needed, and thematically analyzed using grounded theory. METHODS: We conducted 81 interviews with women aged 30-49 either missing from care (n = 21), having unknown HIV status (n = 30) or linked to care (n = 30) within two sites: City of Johannesburg district, Gauteng Province and Mopani district, Limpopo Province. RESULTS: Participants missing from care reported negative staff attitudes, queues, family rejection, medication side effects, and painful blood tests as key deterrents. Participants with an unknown status were deterred by fear of being diagnosed as HIV positive and family rejection, which was similar to women missing from care who often dropped out from care due to actual family rejection. Participants linked to care reported that long queues and staff shortages were challenges but stayed in care due to a will to live for themselves and their children, in addition to counselling and feeling emotionally supported. Interestingly, participants missing from care often accessed medication from friends but, similarly to those with unknown status, noted that they would access care if attended to by supportive nurses and by having non-clinical HIV services. CONCLUSIONS: The accounts of women in this research highlight significant improvements needed to address inequities in the fight against HIV in South Africa. Additionally, the healthcare service access preferences of women aged 30-49 need to be further explored quantitatively in order to design policy relevant interventions.

Understanding HIV service preferences of South African women 30­49 years old missing from or linked to care: An exploratory study of Gauteng and Limpopo provincesThe HIV epidemic in sub-Saharan Africa harms women more than men. South Africa carries the largest share of the global HIV burden, with similar trends seen for women. This study aims to understand 30­49 year-old women's ability to access HIV services in order to reach women missing from HIV care. We conducted 81 interviews with women aged 30­49 either missing from care (n = 21), having unknown status (n = 30) or linked to care (n = 30) within two sites: City of Johannesburg district, Gauteng Province and Mopani district, Limpopo Province. We recruited, informed, and consented participants at clinics and public areas. Interviews were conducted in respondent's preferred languages, transcribed, and translated into English for analysis. Participants missing from care reported negative staff attitudes, queues, family rejection, medication side effects and painful blood tests as key deterrents. Participants with an unknown status were deterred by fear of being diagnosed as HIV positive and family rejection, which was similar to women missing from care who often dropped out from care due to family rejection. Participants linked to care reported that long queues and staff shortages were challenges but stayed in care due to a will to live for themselves and their children, in addition to counselling and feeling emotionally supported. Interestingly, participants missing from care often accessed medication from friends but, similarly to those with unknown status, noted that they would access care if attended to by supportive nurses and by having non-clinical HIV services. The healthcare service access preferences of women aged 30­49 needs to be further explored in order to improve interventions.

Cross-cultural adaptation and psychometric validation of the Chichewa (Malawi) PedsQL™ 4.0 Generic Core Scales child self-report and PedsQL™ 4.0 GCS teen self-report.

BACKGROUND: The PedsQL™ 4.0 Generic Core Scales (GSC) have been translated into over 60 languages, but use in the sub-Saharan African region is limited. This study aimed to cross-culturally adapt and validate the PedsQL™ 4.0 GCS child self-report and teen self-report versions into the Chichewa language for Malawi. METHODS: The English (USA) versions were adapted (translation, back translation and cognitive interviews to evaluate conceptual equivalence) into Chichewa. We recruited 289 children (8-17 years) in Blantyre, Malawi. Classical psychometrics at the item level (missing data, endorsement frequencies, item redundancy) and scale level (internal consistency, convergent, discriminant and known groups validity) was used to evaluate the new Chichewa versions. RESULTS: Six items were found to need cultural adaptation for Malawi. There were problems with missing data (< 5%) and adjacent endorsement frequency (< 10%) among younger children. Internal consistency reliability was acceptable (Cronbach α > 0.7). Convergent validity was generally strong (correlations > 0.4). Discriminant validity (p > 0.05) was evident with respect to gender and age, but not for school grade (p < 0.05). Effect sizes indicating known groups validity were in the expected direction but of variable magnitude. CONCLUSION: We have successfully adapted the PedsQL™ 4.0 GCS child self-report and teen self-report into Chichewa for use in Malawi. Many aspects of the psychometric evaluation were promising, though some elements were more mixed and we have not yet been able to evaluate test-retest reliability or responsiveness. We suggest that the PedsQL™4.0 GCS child and teen self-reports should be used with caution among children and adolescents in Malawi.

PAM50 breast cancer subtypes and survival of patients in rural Ethiopia without adjuvant treatment: a prospective observational study.

PURPOSE: Survival rates of breast cancer (BC) patients are particularly low in rural regions in sub-Saharan Africa (SSA) which is due to limited access to therapy. In recent years, gene expression profiling (GEP) of BC showed a strong prognostic value in patients with local tumour surgery and (neo)adjuvant treatment. The aim of this study was to evaluate the impact of intrinsic subtypes on survival of patients in rural Ethiopia without any (neo)adjuvant therapy. METHODS: In total, 113 female patients from Aira Hospital with histologically proven BC and treated only with surgery were included in this study. All samples were analysed by immunohistochemistry (IHC) for estrogen receptor, progesterone receptor, HER2 and Ki67, as well as RNA-expression analysis for PAM50 subtyping. RESULTS: A positive hormone receptor status was found in 69.0% of the tumours and intrinsic subtyping demonstrated Luminal B to be the most common subtype (34.5%). Follow-up data was available for 79 of 113 patients. Two-year overall survival (OS) was 57.3% and a considerably worse OS was observed in patients with Basal-like BC compared to Luminal A BC. Moreover, advanced tumours showed an increased risk of mortality. CONCLUSION: The OS was very low in the patient cohort that received no (neo)adjuvant treatment. Immunohistochemistry and GEP confirmed endocrine-sensitive tumours in more than half of the patients, with a large proportion of Luminal B, HER2-enriched and Basal-like tumours so that adjuvant chemotherapy should be recommended.

Challenges in evaluating cognitive impairment in diabetics in the Democratic Republic of the Congo.

Dementia is a global public health issue, with 57.5 million people living with at least one type of dementia in 2019 worldwide, and projected to rise to 152 million by 2050. Objective: We assessed the cognitive function in diabetic patients aged 60 or older in Bukavu city, in the eastern Republic of the Congo (DRC). Methods: This case-control study involved 123 patients with established diabetes mellitus (DM) and 123 controls over 60-year-olds also with high rates of illiteracy. Cognitive function was assessed using the Swahili version of the Community Screening Instrument for Dementia (CSI-D). Results: Foremost, our study revealed language-related differences between Swahili spoken in other eastern African countries such as Tanzania and Kenya, where the Swahili CSI-D is readily applied, compared to the Swahili spoken in Bukavu (DRC). Our results also showed that cognitive impairment was present in 18.7% of the total 246 participants. Remarkably, the prevalence rate of cognitive impairment was higher in the non-diabetic group (12.2 versus 25.2%; p=0.009). Participants aged 80 or older were more likely to present with cognitive impairment compared to those aged less than 80 (adjusted odds ratio - aOR=70.27; 95% confidence interval - 95%CI 3.94-125.15; p=0.004). We also found that patients living with DM for more than 20 years were three times more likely to be impaired compared to those who were recently diagnosed with DM (aOR=3.63; 95%CI 1.70-18.81; p=0.026). Conclusion: This study revealed that cognitive impairment was relatively high in Bukavu city. It emphasizes the lack of effective tools to assess cognitive function. This requires, therefore, that research be adapted to the intellect and cultural experiences of the patients.

A demência é uma questão de saúde pública global, afetando 57,5 milhões de pessoas com pelo menos um tipo de demência em 2019 em todo o mundo, com uma previsão de aumento para 152 milhões até 2050. Objetivo: Avaliou-se a função cognitiva em pacientes diabéticos com 60 anos ou mais na cidade de Bukavu, no leste da República Democrática do Congo (RDC). Métodos: Este estudo de caso-controle incluiu 123 pacientes com diabetes mellitus (DM) estabelecido e 123 controles com mais de 60 anos, com altas taxas de analfabetismo. A função cognitiva foi avaliada utilizando a versão swahili do Instrumento de Triagem Comunitária para Demência (Community Screening Instrument for Dementia ­ CSI-D). Resultados: O presente estudo revelou diferenças relacionadas à linguagem entre o swahili falado em outros países do leste da África, como Tanzânia e Quênia, onde o CSI-D swahili é prontamente aplicado, em comparação com o swahili falado em Bukavu (RDC). Observou-se também deficiência cognitiva em 18,7% dos 246 participantes. Notadamente, a taxa de prevalência de deficiência cognitiva foi maior no grupo não diabético (12,2 versus 25,2%; p=0,009). Participantes com 80 anos ou mais tiveram maior probabilidade de apresentar deficiência cognitiva em comparação com aqueles com menos de 80 anos (odds ratios ajustados ­ aOR=70,27; intervalo de confiança de 95% ­ IC95% 3,94­125,15; p=0,004). Também observou-se que pacientes vivendo com DM por mais de 20 anos tinham três vezes mais chances de serem afetados em comparação com aqueles que foram recentemente diagnosticados com DM (aOR=3,63; IC95% 1,70­18,81; p=0,026). Conclusão: Este estudo revelou que a deficiência cognitiva era relativamente alta na cidade de Bukavu. Enfatizou-se a falta de ferramentas eficazes para avaliar a função cognitiva, o que requer, portanto, que a pesquisa seja adaptada ao intelecto e às experiências culturais dos pacientes.

Household Water Treatment Practice and Associated Factors in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Introduction: Household water treatment practices, also known as point-of-use water management, offer means to enhance the overall drinking water quality and reduce the prevalence of diarrheal diseases. Nevertheless, there is a scarcity of information on household water treatment practices and related factors in sub-Saharan Africa. Objective: This study aimed to determine the pooled prevalence of water treatment practices and associated factors in sub-Saharan Africa. Methods: We conducted a search of eligible primary studies in PubMed, Google Scholar, and Hinari, as well as gray literature available in online repositories. The Stata v.17 software was utilized to extract and analyze the data obtained from these studies. To determine the overall pooled prevalence of water treatment practices and their predictors, a weighted inverse-variance random-effects model was employed. We assessed variations across the included studies using forest plots, funnel plots, I 2 statistics, and Egger's tests. Results: In this study, we reviewed a total of 927 articles, 28 of which were eligible for inclusion. The overall pooled prevalence of water treatment practices in sub-Saharan Africa was 36.31(95% CI: 27.64, 44.98). The factors associated with water treatment practices included having formal education (AOR: 2.38, 95% CI: 1.70, 3.34), being male (AOR: 1.78, 95% CI: 1.39, 2.29), having a higher income (AOR: 2.12, 95% CI: 1.39, 3.25), and having received training in water treatment (AOR: 2.25, 95% CI: 1.59, 3.18). Conclusions: In this review, the pooled prevalence of water treatment practices in sub-Saharan Africa was found to be considerably low. Therefore, we recommend that household heads receive enhanced information on water treatment practices through strengthened health education and intensive training in small-scale water treatment practices.

Population Structure and Antimicrobial Resistance in Campylobacter jejuni and C. coli Isolated from Humans with Diarrhea and from Poultry, East Africa.

Campylobacteriosis and antimicrobial resistance (AMR) are global public health concerns. Africa is estimated to have the world's highest incidence of campylobacteriosis and a relatively high prevalence of AMR in Campylobacter spp. from humans and animals. Few studies have compared Campylobacter spp. isolated from humans and poultry in Africa using whole-genome sequencing and antimicrobial susceptibility testing. We explored the population structure and AMR of 178 Campylobacter isolates from East Africa, 81 from patients with diarrhea in Kenya and 97 from 56 poultry samples in Tanzania, collected during 2006-2017. Sequence type diversity was high in both poultry and human isolates, with some sequence types in common. The estimated prevalence of multidrug resistance, defined as resistance to >3 antimicrobial classes, was higher in poultry isolates (40.9%, 95% credible interval 23.6%-59.4%) than in human isolates (2.5%, 95% credible interval 0.3%-6.8%), underlining the importance of antimicrobial stewardship in livestock systems.

Employment, income, and sleep in South Africa: An actor-partner interdependence model approach.

OBJECTIVE: We analyze the relationship between employment status, income, and sleep in South Africa to address two research questions: (1) How does employment status influence the sleep quantity of the individual and their partner? (2) How does income impact the sleep quantity of the individual and their partner? METHOD: Using data from 1600 Black African couples in the South African Time Use Study, we employ the Actor-Partner Interdependence Model to investigate the relationship between employment status, income, and sleep in couples. We categorize nighttime sleep into three categories: recommended sleep (7-9 hours), short sleep (<7 hours), and long sleep (>9 hours). RESULTS: Employed individuals were more likely to get the recommended amount of sleep and less likely to experience long sleep. However, men whose wives are employed are almost twice as likely as men whose wives are unemployed to experience short sleep, and they experience 47% lower risk of long sleep. Men with a medium level of income have a higher risk of short sleep than those with low income, while those in the highest income category are more likely to get the recommended amount of sleep. CONCLUSION: These results highlight the intricate dynamics between managing employment demands and securing economic stability for both men and women in the context of high unemployment and shifting gender norms.

Temporal changes in HIV-related stigma and sexual behaviours: An examination of 22 African countries.

ABSTRACTDespite non-trivial success against the HIV epidemic, health experts in Sub-Saharan Africa (SSA) remain concerned about new infections, stigma attitudes, and increasing rates of higher-risk sexual behaviours (HRSBs). Although this concern has produced voluminous scholarship on the behavioural consequences of belonging to stigmatised populations, scholars have only recently examined the behavioural consequences of holding stigmatising attitudes. Existing work generally finds a positive relationship between stigmatising beliefs and the practice of HRSBs. Yet, it is unknown whether this relationship has changed for countries over the past two decades. We fill this gap using Demographic and Health Survey data from 22 SSA countries. We first find that in most countries, the practice of HRSBs has increased, while stigma beliefs have become more tolerant. Second, the relationship between stigma beliefs and HRSBs changed in only six countries: Nigeria, Kenya, Mozambique, Sierra Leone, Ethiopia, and Lesotho. It changed from non-existent or negative to positive in Nigeria, Kenya, Mozambique, and Ethiopia, but non-existent to negative in Sierra Leone. In Lesotho, the positive association weakened over time. These findings highlight the importance of social and epidemic contexts when considering how stigma impacts sexual behaviours and HIV rates in SSA.
