RESUMEN

Listeria monocytogenes is a concern in seafood and its food processing environment (FPE). Several outbreaks globally have been linked to various types of seafood. Genetic profiling of L. monocytogenes is valuable to track bacterial contamination throughout the FPE and in understanding persistence mechanisms, with limited studies from South Africa. Forty-six L. monocytogenes isolates from origins: Fish/seafood products (n = 32) (salmon, smoked trout, fresh hake, oysters), the FPE (n = 6), and clinical (n = 8) were included in this study. Lineage typing, antibiotic susceptibility testing, and screening for two genes (bcrABC and emrC) conferring sanitizer tolerance was conducted. The seafood and FPE isolates originated from seven different factories processing various seafood products with undetermined origin. All clinical isolates were categorized as lineage I, and seafood and FPE isolates were mostly categorized into lineage II (p < 0.01). Seafood and FPE isolates (53%) carried the bcrABC gene cassette and one fish isolate, the emrC gene. A subset, n = 24, was grouped into serotypes, sequence types (STs), and clonal complexes (CCs) with whole genome sequencing (WGS). Eight CCs and ten STs were identified. All clinical isolates belonged to serogroup 4b, hypervirulent CC1. CC121 was the most prevalent in isolates from food and the FPE. All isolates carried Listeria pathogenicity islands (LIPI) 1 and 2. LIPI-3 and LIPI-4 were found in certain isolates. We identified genetic determinants linked to enhanced survival in the FPE, including stress survival islets (SSI) and genes conferring tolerance to sanitizers. SSI-1 was found in 44% isolates from seafood and the FPE. SSI-2 was found in all the ST121 seafood isolates. Isolates (42%) harbored transposon Tn1688_qac (ermC), conferring tolerance to quaternary ammonium compounds. Five plasmids were identified in 13 isolates from seafood and the FPE. This is the first One Health study reporting on L. monocytogenes genetic diversity, virulence and resistance profiles from various types of seafood and its FPE in South Africa.

RESUMEN

Clinical trials, the empirical discipline of medical experimentation conducted on human subjects, have engendered a paradigm shift in medical research. The need for new clinical studies is paramount in the Middle East and North Africa (MENA) region, with its rising cancer incidence and demand for efficient oncology treatments. This paper comprehensively reviews the challenges, opportunities, and future directions of phase I oncology clinical trials in the MENA region. Early-phase trials are vital in determining drug dosage and assessing toxicity, bridging the gap between preclinical research and clinical practice. Considering the unique landscape of MENA, this review explores regulatory aspects, specific hurdles faced, potential advantages, and areas for improvement in conducting these trials. Various future directions can be pursued to maximize the potential of phase I oncology trials in MENA. While regulatory bodies like the Ministry of Health adhere to the International Conference on Harmonization-Good Clinical Practice guidelines, a unified system meeting high standards would yield better results. Strengthening research infrastructure, establishing research centers, incorporating clinical trial education into the curriculum, and improving access to medical facilities are crucial. Enhancing consumer understanding of research would facilitate increased participation and promote sustainability in trial recruitment. Navigating various funding sources would open the door for more funding opportunities. Collaborations between academia, industry, and regulatory bodies, both international and local, should be fostered to promote knowledge sharing, resource pooling, and harmonization of standards. Such collaborations would contribute to the sustainability of clinical trial activities by leveraging collective expertise, sharing research infrastructure, and distributing the burden of regulatory compliance. By adopting these strategies, the MENA region can advance its capacity to conduct early phases of oncology trials and contribute significantly to the global medical research landscape.

RESUMEN

We sought to investigate the association between hazardous alcohol use and gaps in care for people living with HIV over a long-term follow-up period. Adults who had participated in our previously published Phase I study of hazardous alcohol use at HIV programs in Kenya and Uganda were eligible at their 42 to 48 month follow-up visit. Those who re-enrolled were followed for an additional ~ 12 months. Hazardous alcohol use behavior was measured using the Alcohol Use Disorders Identification Test (AUDIT) tool. Deidentified clinical data were used to assess gaps in care (defined as failure to return to clinic within 60 days after a missed visit). The proportion of patients experiencing a gap in care at a specific time point was based on a nonparametric moment-based estimator. A semiparametric Cox proportional hazard model was used to determine the association between hazardous alcohol use at enrollment in Phase I (AUDIT score ≥ 8) and gaps in care. Of the 731 study-eligible participants from Phase I, 5.5% had died, 10.1% were lost to follow-up, 39.5% transferred, 7.5% declined/not approached, and 37.3% were enrolled. Phase II participants were older, had less hazardous drinking and had a lower WHO clinical stage than those not re-enrolled. Hazardous drinking in the re-enrolled was associated with a Hazard Ratio (HR) of 1.88 [p-value = 0.016] for a gap in care. Thus, hazardous alcohol use at baseline was associated with an increased risk of experiencing a gap in care and presents an early target for intervention.


RESUMEN: Buscamos investigar la asociación entre el uso riesgoso de alcohol y retención en programas de VIH a largo plazo. Todo adulto que participó en nuestro estudio previamente publicado sobre el uso riesgoso de alcohol en programas de VIH en Kenia y Uganda era elegible a los 42 a 48 meses de seguimiento. Los adultos reinscritos en la fueron seguidos por ~ 12 meses adicionales. Usamos el "Alcohol Use Disorders Identification Test" (AUDIT) para medir uso de alcohol. Usamos datos clínicos anonimizados para evaluar interrupciones en cuidado (definido como falta de regresar a clínica 60 días después de faltar a una cita). Basamos la proporción de pacientes con una interrupción en cuidado clínico en un estimador momentáneo y no-paramétrico. Determinamos la asociación entre el uso riesgoso de alcohol al inicio de la primera fase (puntuación AUDIT ≥8) con retención en servicios clínicos usando un modelo de riesgo Cox semiparamétrico. De los 731 participantes elegibles, 5.5% habían muerto, 10.1% fueron perdidos a seguimiento clínico, 39.5% se transfirieron a otro programa, 7.5% declinaron participación o no fueron reclutados y 37.3% fueron reinscritos en la segunda fase. Los participantes reinscritos eran mayores, tenían menos uso riesgoso de alcohol y tenían VIH menos avanzado. El uso peligroso del alcohol se vio asociado con el riesgo de tener una interrupción en cuidado clínico [Proporción de Riesgo (Hazard Ratio, HR) PR=1.88, valor-p = 0.016]. Por lo tanto, el uso peligroso del alcohol incrementa el riesgo de perder seguimiento clínico y presenta una oportunidad para intervención.

RESUMEN

BACKGROUND: Maternal and neonatal deaths remain a major public health issue worldwide. Income Generation Associations (IGAs) could form a critical entry point to addressing poverty-related contributors. However, there have been limited practical interventions to leverage the power of IGAs in addressing the challenges associated with maternal care and childcare. OBJECTIVE: This study aims to co-design an intervention package with women in IGAs to improve their readiness and resilience to address maternal and child health (MCH) challenges using a human-centered design approach. METHODS: The study will use a qualitative descriptive design with purposefully selected women in IGAs and key MCH stakeholders in the Shinyanga and Arusha Regions of Tanzania. A 4-step adaptation of the human-centered design process will be used involving (1) mapping of IGAs and exploring their activities, level of women's engagement, and MCH challenges faced; (2) co-designing of the intervention package to address identified MCH challenges or needs considering the perceived acceptability, feasibility, and sustainability; (3) validation of the emerging intervention package through gathering insights of women in IGAs who did not take part in initial steps; and (4) refinement of the intervention package with MCH stakeholders based on the validation findings. RESULTS: The participants, procedures, and findings of each co-design step will be presented. More specifically, MCH challenges facing women in IGAs, a list of potential solutions proposed, and the emerging prototype will be presented. As of August 2024, we have completed the co-design of the intervention package and are preparing validation. The findings from the validation of the emerging prototype with a new group of women in IGAs and its refinement through multistakeholder engagement will be presented. A final co-designed intervention package with the potential to improve women's resilience and readiness to handle MCH challenges will be generated. CONCLUSIONS: The emerging intervention package will be discussed given relevant literature on the topic. We believe that subsequent testing and refinement of the package could form the basis for scaling up to broader settings and that the package could then be promoted as one of the key strategies in addressing MCH challenges facing women in low- and middle-income countries.

RESUMEN

PURPOSE: To investigate the psychometric properties of the MOSE-Benin, a French-language version of the Measure of Stroke Environment (MOSE) for Sub-Saharan Africa. MATERIALS AND METHODS: The original English version of the MOSE has been translated into French following the guidelines for cross-cultural adaptation. The resulting questionnaire (MOSE-Benin) was administered to a convenience sample of participants recruited in Benin, a French-speaking country. RESULTS: Eighty-two stroke survivors (41 females; mean ± SD: 54.94 ± 11.6 years old) participated in the study. Internal consistency of each domain of the MOSE-Benin and the overall questionnaire was high (Cronbach's α: 0.78 to 0.92). Test-retest reliability was excellent (n = 31; ICC: 0.977 to 0.998). Overall, the standard error of measurement (SEM) and the minimum detectable change (MDC) showed very low values (SEM = 0.85; MDC = 2.35). Convergent validity demonstrated moderate correlations for the three domains in separate comparison respectively with the ACTIVLIM-Stroke questionnaire, the Participation Measurement Scale, and the communication domain of the Stroke Impact Scale (r or ρ: 0.42 to 0.54; p < 0.0001). CONCLUSION: MOSE-Benin has good evidence regarding psychometric properties (i.e., content validity, convergent validity, internal consistency, and test-retest reliability) that can support its use for the assessment of perceived environmental barriers after stroke in a French-speaking Sub-Saharan African country, such as Benin.


Stroke survivors in French-speaking Sub-Saharan Africa may face environmental challenges related to acceptability, physical environment, and communication.Stroke survivors should be assessed in their communities to identify environmental barriers, using valid and robust tools.A French version of the MOSE (MOSE-Benin) is now available and can be used to assess the environmental concerns faced by stroke survivors in Sub-Saharan Africa.

RESUMEN

Linkage to HIV care remains suboptimal among men. We investigated the effectiveness of a male-targeted HIV-specific decision support app, Empowering People through Informed Choices for HIV (EPIC-HIV), on increasing linkage to HIV care among men in rural South Africa. Home-Based Intervention to Test and Start (HITS) was a multi-component cluster-randomized controlled trial conducted among 45 communities in uMkhanyakude, KwaZulu-Natal. The development of EPIC-HIV was guided by self-determination theory and human-computer interaction design to increase intrinsic motivation to seek HIV testing and care among men. EPIC-HIV was offered in two stages: EPIC-HIV 1 at the time of home-based HIV counseling and testing (HBHCT), and EPIC-HIV 2 at 1 month after a positive HIV diagnosis if not linked to care. Sixteen communities were randomly assigned to the arms to receive EPIC-HIV, and 29 communities to the arms without EPIC-HIV. Among all eligible men, we compared linkage to care (initiation or resumption of antiretroviral therapy after > 3 months of care interruption) at local clinics within 1 year of a home visit, ascertained from individual clinical records. Intention-to-treat analysis was performed using modified Poisson regression with adjustment for receiving another intervention (i.e., financial incentives) and clustering at the community level. We also conducted a satisfaction survey for EPIC-HIV 2. A total of 13,894 men were eligible (i.e., aged ≥ 15 years and resident in the 45 communities). The mean age was 34.6 (±16.8) years, and 65% were married or in an informal union. Overall, 20.7% received HBHCT, resulting in 122 HIV-positive and 6 discordant tests. Among these, 54 men linked to care within 1 year after HBHCT. Additionally, of the 13,765 eligible participants who did not receive HBHCT or received HIV-negative results, 301 men linked to care within 1 year. Overall, only 13 men received EPIC-HIV 2. The proportion of linkage to care did not differ between the arms randomized to EPIC-HIV and those without EPIC-HIV (adjusted risk ratio = 1.05; 95% CI:0.86-1.29). All 13 men who used EPIC-HIV 2 reported the app was acceptable, user-friendly, and useful for getting information on HIV testing and treatment. The reach was low, although the acceptability and usability of the app were very high among those who engaged with it. Enhanced digital support applications could form part of interventions to increase knowledge of HIV treatment among men. Clinical Trial Number: ClinicalTrials.gov # NCT03757104.

RESUMEN

HIV and substance abuse are common among young men, associated with a cluster of risk behaviors. Yet, most services addressing these challenges are delivered in setting underutilized by men and are often inconsistent with male identity. This cluster randomized controlled trial aimed to reduce multiple risk behaviors found among young men township areas on the outskirts of Cape Town, South Africa. Young men aged 18-29 years (N = 1193) across 27 neighborhoods were randomized by area to receive HIV-related skills training during either: (1) a 12-month soccer league (SL) intervention; (2) 6-month SL followed by 6 months of vocational training (VT) intervention (SL/VT, n = 9); or 3) a control condition (CC). Bayesian longitudinal mixture models were used to evaluate behaviors over time. Because we targeted multiple outcomes as our primary outcome, we analyzed if the number of significantly different outcomes between conditions exceeded chance for 13 measures over 18 months (with 83%, 76%, and 61% follow-up). Only if there were three significant benefits favoring the SL/VT over the SL would benefits be significant. Outcome measures included substance use, HIV-testing, protective sexual behaviors, violence, community engagement and mental health. Consistent participation in the SL was typically around 45% over time across conditions, however, only 17% of men completed SL/VT. There were no significant differences between conditions over time based on the number of study outcomes. These structural interventions were ineffective in addressing young men's substance abuse and risk for HIV.Clinical Trial Registration: This trial was prospectively registered on 24 November 2014 with ClinicalTrials.gov (NCT02358226).

RESUMEN

PURPOSE: The urinary tract is colonized by microbial communities that impact urinary health. Previous studies have suggested that the bacterial composition of the male urinary microbiota is related to STIs. This study assessed the bacterial composition of the urinary microbiome in South African MSM with and without C. trachomatis. METHODS: This study used urine samples from MSM attending care at the King Edward VIII hospital and the Aurum Institute in Durban, South Africa. A total of 200 samples were tested for C. trachomatis infection using the Applied Biosystems™ TaqMan® Assays. Urinary microbiomes of 23 samples were characterized using 16 S rRNA (V3 and V4) gene sequencing on the Illumina MiSeq platform. RESULTS: Bacterial taxonomic analysis showed a high abundance of Streptococcus, Corynebacterium, and Staphylococcus in all the sequenced samples. Moreover, Prevotella and Lactobacillus were detected in urine samples of MSM. Alpha diversity metrics showed a slight increase in microbial diversity in C. trachomatis positive samples; however, this was not significant (ANOVA, P > 0.05). Principal coordinates analysis (PCoA) showed that the microbiome of C. trachomatis infected MSM was not clearly different from those uninfected. Distinct bacterial communities were not detected between positive and negative samples (PERMANOVA F1,22= 1.0284, R2 = 0.047%, P = 0.385). CONCLUSION: Most microbiome studies on MSM to date have focused on the gut microenvironment. Few studies, however, have provided data regarding the normal composition of the male urethral microbiomes or if these microbiomes are associated with male STIs. This study adds to the growing body of knowledge highlighting the urinary microbiome in MSM.

RESUMEN

Background: The epidemiology of inflammatory bowel disease (IBD) has changed rapidly in recent years. Objective data concerning the IBD burden in the Middle East and North Africa (MENA) region is limited. We aimed to provide a systematic report on the IBD burden in the MENA region. Additionally, we aimed to study the age- and sex-specific trends in IBD incidence, prevalence and mortality rates from 1990-2019. Methods: Using the Global Burden of Disease (GBD) 2019 Study Database, we investigated the changes in incidence, prevalence and mortality rate, and disability-adjusted life-years (DALYs), at a regional and country level between 1990 and 2019. Results: In 2019, there were 282,534 cases (95% confidence interval [CI] 239,506-334,478) of IBD in the MENA region (50.5% male). There was an overall increase in the incidence and prevalence rates of IBD in the MENA region from 1990 to 2019, while a simultaneous decrease in overall mortality rates was identified. Incidence rates were highest in Jordan, at 6.9 (95%CI 5.8-8.1) per 100,000, and lowest in Morocco, at 1.6 (95%CI 1.4-2) per 100,000. From 1990-2019, the incidence was found increased in males at a higher rate than in females. The age-standardized mortality rate decreased for both sexes by 24% from 1990-2019. Conclusion: The trends and geographic variations in IBD within the MENA region provide policymakers with vital information for making informed decisions in policy, research, and investment, thereby enabling the development of more effective strategies and better allocation of resources.

RESUMEN

Introduction: Alzheimer's disease represents a substantial and escalating public health threat across Africa. Alzheimer's disease leads to substantial cognitive impairment and memory loss, placing a heavy burden on the affected individuals and their families, friends, and caregivers. It affects 2.67 million people in Africa, the majority of whom live in sub-Saharan Africa. The prevalence of this disease is expected to rise drastically to approximately 150 million individuals worldwide by 2050, as estimated by the WHO. Aim: This paper offers an integrative profile of Alzheimer's disease in Africa, spanning known genetic and modifiable risks, discusses the existing challenges in diagnosis and treatment, projections on prevalence and disability-adjusted life year burden through 2050, and priority policy responses needed to rebalance the equation. Methods: This paper examines available literature to summarize current knowledge on risk factors, diagnosis, treatments, and burden of Alzheimer's disease in Africa. Gather epidemiological assessments, clinical guidelines, and commentary related to Alzheimer's disease in Africa. Results: The data reveals concerning realities regarding Alzheimer's disease diagnosis and care in Africa. Diagnostic infrastructure shortcomings, resource limitations, and knowledge gaps emerge as recurring barriers. Positron emission tomography scans, cerebrospinal fluid assays, and other mainstay detection modalities common in developed countries show restricted availability. Conclusion: Addressing Africa's Alzheimer's disease crisis demands a multipronged strategy to uplift diagnostic capacities, treatment availability, specialist training, public awareness, and coordinated policymaking. Prioritizing biomarkers and imaging to confirm early neurodegeneration is foundational, alongside drug access expansion.

RESUMEN

OBJECTIVE: To evaluate the impact of Truenat assays on the diagnosis of TB at peripheral facilities in Nigeria. METHODS: This was a retrospective cross-sectional study across 34 out of 38 Truenat-implementing facilities in Nigeria. These facilities offer DOTS services. Information on turnaround time (TAT) for TB diagnosis and time to commencement of treatment was obtained. Also, trends in TB case notifications at the facilities 9 months prior to and 9 months during Truenat implementation were compared. RESULTS: Of 2,335 entries, 70.1% (1,636) were used to determine TAT, while 45.8% (n = 1,070) were used for time to treatment initiation. The median time to diagnosis was <24 hours (IQR 0-1 days). The majority (57.9%) were diagnosed in <24 hours. The median time to treatment initiation was 1.5 days (IQR 0-3). In 9 months before the introduction of Truenat, 8% of 20,424 presumptives evaluated were positive for TB, while during the implementation, 9% of 37,087 presumptives were positive for TB. CONCLUSION: Truenat deployment led to an increase in TB and DR-TB case detection in peripheral facilities in Nigeria. It also decreased TAT and time to TB treatment initiation. These have positive implications in the fight against TB, and Truenat is relevant in finding missing TB cases in Nigeria.


OBJECTIF: Évaluer l'impact des tests Truenat sur le dépistage de la TB dans les centres de santé périphériques du Nigeria. MÉTHODES: Il s'agit d'une recherche transversale rétrospective menée dans 34 des 38 établissements ayant adopté le test Truenat au Nigeria. Ces établissements fournissent des services DOTS. Les données concernant le délai de diagnostic de la TB (TAT, pour l'anglais « turnaround time ¼) et le délai de début du traitement ont été recueillies. De plus, une comparaison a été faite sur la tendance de la notification des cas de TB dans les établissements neuf mois avant et neuf mois pendant la mise en œuvre de Truenat. RÉSULTATS: Sur un total de 2 335 entrées, 70,1% (1 636) ont été utilisées pour déterminer le TAT, tandis que 45,8% (n = 1 070) ont été utilisées pour déterminer le délai de mise en route du traitement. Le délai médian avant le diagnostic était inférieur à 24 h (IQR 0­1 jour). La majorité des cas (57,9%) ont été diagnostiqués en moins de 24 h. Le délai médian d'initiation du traitement était de 1,5 jour (IQR 0­3). Sur une période de 9 mois précédant l'introduction de Truenat, 8% des 20 424 présomptions évaluées étaient positives à la TB, tandis que pendant la mise en œuvre, 9% des 37 087 présomptions étaient positives à la TB. CONCLUSION: L'implémentation du Truenat a favorisé une augmentation de la détection des cas de TB et de DR-TB dans les centres de santé périphériques du Nigeria. De plus, cela a contribué à réduire le TAT et le délai d'initiation du traitement de la TB. Ces résultats ont un impact positif dans la lutte contre la TB, et le Truenat s'avère être un outil précieux pour repérer les cas de TB manquants au Nigeria.

RESUMEN

BACKGROUND: Cardiovascular diseases (CVDs), a significant global health concern, are responsible for 13% of all deaths particularly in Africa, where they contribute substantially to the global disease burden, taking several millions of lives globally and annually. Despite advancements in healthcare, the burden of CVDs continues to rise steadily. This comprehensive review critically examines the intersection of artificial intelligence (AI) and cardiovascular disease (CVD) management in Africa. Drawing on a diverse gamut of scholarly literature and empirical evidence, the review assesses the prevalence, impact, and challenges of CVDs in the African context. MAIN BODY: The review highlights the potential of AI technologies to revolutionize CVD care, offering insights into its applications in diagnosis, treatment optimization, and remote patient monitoring. It explores existing literature sourced from databases like PUBMED, Scopus and Google Scholar about the current state of AI implementation in African healthcare systems, which are majorly resource-constrained, discussing successes, limitations, and future prospects. The work includes the prevalence and impact of CVDs in Africa, noting the significant public health burden and economic implications. Current challenges in addressing CVDs are outlined, focusing on resource constraints, healthcare system challenges, and socioeconomic factors. Our review takes a dive into AI's role in healthcare, emphasizing its capabilities in disease diagnosis, treatment optimization, and patient monitoring, and presents current applications and case studies of AI in African cardiovascular healthcare. It also addresses the challenges and limitations of implementing AI in this context, such as inadequate infrastructure, lack of high-quality data, and the need for regulatory frameworks. CONCLUSION: Our review emphasizes the urgent need for collaborative efforts among policymakers, healthcare providers, and researchers to overcome barriers to AI integration and ensure equitable access to innovative healthcare solutions. By fetching existing research and offering practical recommendations, this review contributes to the academic discourse on AI-driven healthcare interventions in Africa, offering an understanding of the opportunities and challenges in leveraging technology to address pressing public health concerns. It calls for increased research, investment, and collaboration to harness AI's full potential in transforming cardiovascular healthcare in Africa.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Post-discharge malaria chemoprevention (PDMC) is an intervention aimed at reducing morbidity and mortality in patients hospitalized with severe anaemia, with its effectiveness established in several clinical trials. The aim of this study was to better understand factors that would influence the scale up of this intervention, and to identify preferences for two delivery mechanisms, facility-based or community-based. METHODS: Forty-six qualitative individual interviews were conducted in five sub-Saharan countries amongst malaria key opinion leaders and national decision makers. Findings were analysed following a thematic inductive approach. RESULTS: Half of participants were familiar with PDMC, with a satisfactory understanding of the intervention. Although PDMC was perceived as beneficial by most respondents, there was some unclarity on the target population. Both delivery approaches were perceived as valuable and potentially complementary. From an adoption perspective, relevant evidence generation, favorable policy environment, and committed funding were identified as key elements for the scale up of PDMC. CONCLUSIONS: The findings suggest that although PDMC was perceived as a relevant tool to prevent malaria, further clarification was needed in terms of the relevant patient population, delivery mechanisms, and more evidence should be generated from implementation research to ensure policy adoption and funding.

RESUMEN

Introduction: Despite the efforts and support of the World Health Organization and other international organizations to reduce the incidence of the disease, tetanus is still an acute condition with serious consequences, including death. The purpose of this study was to assess the tetanus patients we have been monitoring over the past two years in Somalia, a country with a protracted civil conflict, extreme poverty, and restricted access to hospital, social security, and public health facilities. Methods: This study includes tetanus patients who were admitted to the Recep Tayyip Erdogan Training and Research Hospital in Mogadishu, Somalia, Turkey between January 1, 2022, and November 1, 2023. Hospitalization, diagnosis, treatment, complications, death, and test results were all looked at in addition to the patients' sociodemographic details. Results: The average age of the 196 patients was 10 years, with males making up 67.9% of the total (min-max: 7 days-71 years). Acute injury was the cause of 53.1% of tetanus cases, with the legs being the most frequently injured body area (28.8%). A mean duration of stay of 11 days was observed for 82.1% of the patients who were monitored in the hospital (min-max: 1-38 days). The total fatality rate was 14.3%, and 85.7% of patients had never had a tetanus vaccination. The group with severe tetanus had higher rates of intensive care admission (p<0.001), generalized/neonatal tetanus (p<0.001), high non-vaccination rate (p:0.011), antibiotic usage (p<0.001), and a positive blood culture (p<0.001). Almost all of the complications (p<0.001) and all of the deaths (p<0.001) were in the severe group. Conclusion: In sub-Saharan Africa, immunization rates are regrettably still insufficient despite the tetanus vaccine's low cost and great effectiveness. Public education and encouragement on anti-vaccination must continue alongside the enhancement of vaccination programs. Otherwise, low- and middle-income countries will still be plagued by this illness, which has been overlooked in high-income nations.

RESUMEN

The presence of livestock inside protected areas, or "livestock encroachment," is a global conservation concern because livestock is broadly thought to negatively affect wildlife. The Maasai Mara National Reserve (MMNR), Kenya, exemplifies this tension as livestock is believed to have resulted in the declining wildlife populations, contributing to the strict and sometimes violent exclusion measures targeting Maasai pastoralists. However, research embedded in the real-world setting that draws insights from the social-ecological contexts is lacking. In this study, we conducted 19 mo of ecological monitoring covering 60 sites in MMNR and found that cattle presence inside the reserve did not significantly impact most co-occurring wild herbivores at the current intensity. Using the Hierarchical Modeling of Species Communities and Gaussian copula graphic models, we showed that cattle had no direct associations-neither negative nor positive-with nearly all wild herbivores despite frequently sharing the same space. Moreover, we did not detect resource degradation correlated with cattle presence near the MMNR boundary. Given the colonial legacy and land use history of Mara, entering MMNR becomes the only viable option for many herders. These results corroborate the emerging perspective that the ecological impacts of extensively herded livestock on wildlife might be more nuanced than previously thought. To effectively balance the needs of people, livestock, and wildlife, the current rigid livestock exclusion measures need to be reassessed to holistically consider herbivore ecology, local land use history, and modern politics of protected area management.

RESUMEN

Breast cancer is by far the leading cancer both in terms of incidence and mortality in the Republic of Mauritius, a Small Island Developing State (SIDS). However, few studies assessed its survival by age, stage at diagnosis and molecular subtype. We identified 1399 breast cancer cases newly diagnosed between 2017 and 2020 at the Central Health Laboratory, Victoria Hospital. Cancers were categorized into five molecular subtypes: (1) luminal A, (2) luminal B Her2 negative, (3) luminal B Her2 positive, (4) Her2 enriched and (5) Triple negative. The net 1 and 3-year survival were estimated for different age groups, staging at time of diagnosis and molecular subtype. We also estimated the excess hazards using a multivariate Cox proportional hazards model. While early stage at diagnosis (stage 1 [44.4%] and stage 2 [20.1%]) were most common compared to late presentation (Stage 3 [25.4%] and stage 4 [10.1%]), luminal B Her2 negative (36.7%) was the most frequent molecular subtype. The net 1- and 3-year breast cancer survival rates were 93.9% (92.3-95.4) and 83.4% (80.4-86.4), respectively. Breast cancer three-year survival rates were poorest among the youngest patients (<50 years), 77.1% (70.7-83.5), those diagnosed with stage 4 (28.5% [17.1-39.9]) and cancer with a triple negative molecular subtype (71.3% [63.3-79.3]). Emphasis on a national breast cancer screening programme, down staging breast cancer at diagnosis and systematic molecular subtyping of all breast tissues could be pivotal in improving breast cancer survival outcomes in the Republic of Mauritius.

RESUMEN

Social networks expand rapidly in adolescence, increasing HIV status disclosure considerations and concerns for young people living with HIV, especially in settings where HIV-related stigma is prevalent. This study examines HIV disclosure and enacted stigma among adolescents and young adults living with HIV in South Africa. This study uses survey data from a sample of 1186 youth living with HIV, aged 14-24, and enrolled in peer support groups led by community-based organizations in KwaZulu Natal and Gauteng provinces, South Africa. Study participants completed a questionnaire on sociodemographic details, physical health, school attendance, who knew the individual's HIV status, and experiences of HIV-related mistreatment. Mixed effects logistic regression examined the association between experiences of HIV-related mistreatment and factors that may inadvertently disclose one's status, such as poor physical health and missed school, and knowledge of an individual's HIV-positive status by their caregiver, household, friends, educators, and most recent sexual partner. Almost a quarter of the sample reported an experience of HIV-related mistreatment in the past six months. After controlling sociodemographic characteristics, missed school due to illness (AOR = 1.75, 95% CI = 1.27-2.43), and knowledge of HIV status by non-family members (AOR = 2.19, 95% CI = 1.60-3.00) were significantly associated with HIV-related mistreatment. Findings suggest that experiences of enacted stigma are common among youth and linked to poor physical health and knowledge of HIV status outside the family. Effective community-level stigma reduction interventions are urgently needed. In the meantime, adolescents need individualized disclosure counseling and support managing their physical health to prevent further inadvertent disclosure and discrimination.

RESUMEN

A phytopathogenic strain of Pectobacterium polaris (designated SRB2) was isolated for the first time in South Africa from a potato tuber affected by soft rot. The draft genome of strain SRB2 encodes various plant cell wall-degrading enzymes and genes associated with biofilm formation and virulence. Antibiotic resistance genes were not detected.
