RESUMEN

BACKGROUND: HIV prevalence among people who use drugs (PWUD) in Tanzania is 4-7 times higher than in the general population, underscoring an urgent need to increase HIV testing and treatment among PWUD. Drug use stigma within HIV clinics is a barrier to HIV treatment for PWUD, yet few interventions to address HIV-clinic drug use stigma exist. Guided by the ADAPT-ITT model, we adapted the participatory training curriculum of the evidence-based Health Policy Plus Total Facility Approach to HIV stigma reduction, to address drug use stigma in HIV care and treatment clinics (CTCs). METHODS: The first step in the training curriculum adaptation process was formative research. We conducted 32 in-depth interviews in Dar es Salaam, Tanzania: 18 (11 men and 7 women) with PWUD living with HIV, and 14 with a mix of clinical [7] and non-clinical [7] CTC staff (5 men and 9 women). Data were analyzed through rapid qualitative analysis to inform initial curriculum adaptation. This initial draft curriculum was then further adapted and refined through multiple iterative steps of review, feedback and revision including a 2-day stakeholder workshop and external expert review. RESULTS: Four CTC drug use stigma drivers emerged as key to address in the curriculum adaptation: (1) Lack of awareness of the manifestations and consequences of drug use stigma in CTCs (e.g., name calling, ignoring PWUD and denial of care); (2) Negative stereotypes (e.g., all PWUD are thieves, dangerous); (3) Fear of providing services to PWUD, and; (4) Lack of knowledge about drug use as a medical condition and absence of skills to care for PWUD. Five, 2.5-hour participatory training sessions were developed with topics focused on creating awareness of stigma and its consequences, understanding and addressing stereotypes and fears of interacting with PWUD; understanding drug use, addiction, and co-occurring conditions; deepening understanding of drug use stigma and creating empathy, including a panel session with people who had used drugs; and working to create actionable change. CONCLUSION: Understanding context specific drivers and manifestations of drug use stigma from the perspective of PWUD and health workers allowed for ready adaptation of an existing evidence-based HIV-stigma reduction intervention to address drug use stigma in HIV care and treatment clinics. Future steps include a pilot test of the adapted intervention.

RESUMEN

BACKGROUND: Despite the scale-up of ART and the rollout in Tanzania of dolutegravir, an integrase strand transfer inhibitor (INSTI), treatment success has not been fully realized. HIV drug resistance (HIVDR), including dolutegravir resistance, could be implicated in the notable suboptimal viral load (VL) suppression among HIV patients. OBJECTIVES: To determine the prevalence and patterns of acquired drug resistance mutations (DRMs) among children and adults in Tanzania. METHODS: A national cross-sectional HIVDR survey was conducted among 866 children and 1173 adults. Genotyping was done on dried blood spot and/or plasma of participants with high HIV VL (≥1000 copies/mL). HIV genes (reverse transcriptase, protease and integrase) were amplified by PCR and directly sequenced. The Stanford HIVDR Database was used for HIVDR interpretation. RESULTS: HIVDR genotyping was performed on blood samples from 137 participants (92 children and 45 adults) with VL ≥ 1000 copies/mL. The overall prevalence of HIV DRMs was 71.5%, with DRMs present in 78.3% of children and 57.8% of adults. Importantly, 5.8% of participants had INSTI DRMs including major DRMs: Q148K, E138K, G118R, G140A, T66A and R263K. NNRTI, NRTI and PI DRMs were also detected in 62.8%, 44.5% and 8% of participants, respectively. All the participants with major INSTI DRMs harboured DRMs targeting NRTI backbone drugs. CONCLUSIONS: More than 7 in 10 patients with high HIV viraemia in Tanzania have DRMs. The early emergence of dolutegravir resistance is of concern for the efficacy of the Tanzanian ART programme.

RESUMEN

High-throughput Plasmodium genomic data is increasingly useful in assessing prevalence of clinically important mutations and malaria transmission patterns. Understanding parasite diversity is important for identification of specific human or parasite populations that can be targeted by control programmes, and to monitor the spread of mutations associated with drug resistance. An up-to-date understanding of regional parasite population dynamics is also critical to monitor the impact of control efforts. However, this data is largely absent from high-burden nations in Africa, and to date, no such analysis has been conducted for malaria parasites in Tanzania countrywide. To this end, over 1,000 P. falciparum clinical isolates were collected in 2017 from 13 sites in seven administrative regions across Tanzania, and parasites were genotyped at 1,800 variable positions genome-wide using molecular inversion probes. Population structure was detectable among Tanzanian P. falciparum parasites, approximately separating parasites from the northern and southern districts and identifying genetically admixed populations in the north. Isolates from nearby districts were more likely to be genetically related compared to parasites sampled from more distant districts. Known drug resistance mutations were seen at increased frequency in northern districts (including two infections carrying pfk13-R561H), and additional variants with undetermined significance for antimalarial resistance also varied by geography. Malaria Indicator Survey (2017) data corresponded with genetic findings, including average region-level complexity-of-infection and malaria prevalence estimates. The parasite populations identified here provide important information on extant spatial patterns of genetic diversity of Tanzanian parasites, to which future surveys of genetic relatedness can be compared.

RESUMEN

BACKGROUND: Anemia in pregnancy is behind a significant burden of maternal mortality and poor birth outcomes globally. Efforts to address it need evidence on trends and its pertinent factors as they vary from one area to another. METHODS: We pooled data of 23,203 women of reproductive age whose hemoglobin levels were measured from two Tanzania Demographic and Health Surveys (TDHS). Of them, 2,194 women were pregnant. Analyses employed descriptive analyses to determine the burden of anemia, its characteristics, and severity; GIS mapping to determine the regional changes of anemia between 2005 and 2015; and logistic regression to determine the remaining determinants of anemia among pregnant women using Stata 15. RESULTS: The burden of anemia among pregnant women in Tanzania has remained unprecedently high, and varies between regions. There was no significant decline of anemia in general between the two periods after adjusting for individual, households, reproductive, and child characteristics [AOR = 0.964, 95% CI = 0.774-1.202, p = 0.747). Anemia is currently prevalent in 57% of pregnant women in Tanzania. The prevalence is more likely to be higher among women aged 15-19 years than those aged between 20-34 years. It is more likely to be prevalent among those within large families, with no formal education, food insecurity, lack of health insurance, had no antimalaria during pregnancy, and had low frequency of ANC attendance. On the other hand, delivery in a health facility may be potentially protective against anemia. CONCLUSIONS: Anemia in pregnancy remained persistently high and prevalent among 57% of pregnant women in Tanzania. Efforts to address anemia are crucial and need to be focused in regions with increasing burden of anemia among pregnant women. It is imperative to address important risk factors such as food insecurity, strengthening universal health coverage, empowering women of reproductive age with education and especially nutritional knowledge and advocating for early antenatal booking, attendance, and facility delivery.

RESUMEN

People living with HIV often experience mental health disorders and engage in substance use. Evidence, however, is limited about the influence of mental health disorders and substance use on non-adherence to ART. We conducted a cross-sectional study among 682 HIV-positive people on ART in Nepal. We measured their depressive symptoms, anxiety, stress levels, substance use, and non-adherence to ART. We developed logistic regression models to examine the association of mental health disorders and substance use with non-adherence to ART. Experiencing depressive symptoms was positively associated with ART non-adherence among HIV-positive people (men: AOR = 2.77, p = .001; women: AOR = 3.69, p = .001). Additionally, both men and women were more likely to have non-adherence to ART when they had anxiety (men: AOR = 2.19, p = .022; women AOR = 2.83, p = .001) and higher stress scores (men: AOR = 1.11, p = .001; women: AOR = 1.08, p = .001). While substance use was associated with non-adherence only in HIV-positive men (AOR = 3.12, p < .001). Depressive symptoms, anxiety, and high level of stress had negative roles on adherence in HIV-positive men and women. While substance use had a negative role on ART adherence among men only. Results highlight that the HIV-positive people should be screened and provided treatment and psychosocial support while providing ART services to improve their medication adherence.

RESUMEN

BACKGROUND: HIV-positive people often experience mental health disorders and engage in substance use when the disease progresses. In resource limited settings, mental health services are not integrated into HIV services. In Nepal, HIV-positive people do receive psychosocial support and other basic health care services from a community home-based care intervention; however, the effects of the intervention on health outcomes is not yet known. Therefore, we examined the impact of the intervention on mental health and antiretroviral therapy (ART) adherence. METHODS: We conducted an intervention study to identify the effects of a community home-based care intervention on mental health disorders, substance use, and non-adherence to ART among HIV-positive people in Nepal from March to August 2015. In total, 344 participated in the intervention and another 338 were in the control group. The intervention was comprised of home-based psychosocial support and peer counseling, adherence support, basic health care, and referral services. We measured the participants' depression, anxiety, stress, substance use, and non-adherence to ART. We applied a generalized estimating equation to examine the effects of intervention on health outcomes. RESULTS: The intervention had positive effects in reducing depressive symptoms [Adjusted Odds Ratio (AOR) = 0.44, p < 0.001)], anxiety (AOR = 0.54, p = 0.014), stress (ß = - 3.98, p < 0.001), substance use (AOR = 0.51, p = 0.005), and non-adherence to ART (AOR = 0.62, p = 0.025) among its participants at six-month follow-up. CONCLUSIONS: The intervention was effective in reducing mental health disorders, substance use, and non-adherence to ART among HIV-positive people. Community home-based care intervention can be applied in resource limited setting to improve the mental health of the HIV-positive people. Such intervention should be targeted to include more HIV-positive people in order to improve their ART adherence.

RESUMEN

BACKGROUND: Human resource for health crisis has impaired global efforts against malaria in highly endemic countries. To address this, the World Health Organization (WHO) recommended scaling-up of community health workers (CHWs) and related cadres owing to their documented success in malaria and other disease prevention and management. Evidence is inconsistent on the roles and challenges they encounter in malaria interventions. This systematic review aims to summarize evidence on roles and challenges of CHWs and related cadres in integrated community case management for malaria (iCCM). METHODS: This systematic review retrieved evidence from PubMed, CINAHL, ISI Web of Knowledge, and WHO regional databases. Terms extracted from the Boolean phrase used for PubMed were also used in other databases. The review included studies with Randomized Control Trial, Quasi-experimental, Pre-post interventional, Longitudinal and cohort, Cross-sectional, Case study, and Secondary data analysis. Because of heterogeneity, only narrative synthesis was conducted for this review. RESULTS: A total of 66 articles were eligible for analysis out of 1380 studies retrieved. CHWs and related cadre roles in malaria interventions included: malaria case management, prevention including health surveillance and health promotion specific to malaria. Despite their documented success, CHWs and related cadres succumb to health system challenges. These are poor and unsustainable finance for iCCM, workforce related challenges, lack of and unsustainable supply of medicines and diagnostics, lack of information and research, service delivery and leadership challenges. CONCLUSIONS: Community health workers and related cadres had important preventive, case management and promotive roles in malaria interventions. To enable their effective integration into the health systems, the identified challenges should be addressed. They include: introducing sustainable financing on iCCM programmes, tailoring their training to address the identified gaps, improving sustainable supply chain management of malaria drugs and diagnostics, and addressing regulatory challenges in the local contexts.

RESUMEN

High prevalence of human immunodeficiency virus (HIV) among females who use drugs in Dar es Salaam, Tanzania, contrasts strikingly with their low enrollment in HIV risk reduction services such as methadone assisted therapy (MAT). We conducted a case-control study to examine factors associated with non-enrollment in MAT, with a focus on gender-based violence. We interviewed 202 female heroin users not enrolled in MAT as cases and 93 females enrolled in MAT. We fitted logistic regression models with MAT enrollment as the outcome of interest. The likelihood of MAT enrollment decreased upon being in a violent relationship [odds ratio (OR) 0.23; 95 % CI 0.11-0.40], with experience of discrimination by a healthcare provider (OR 0.11; 95 % CI 0.04-0.35), and having a partner who also uses drugs (OR 0.05; 95 % CI 0.01-0.26). The results indicate that violence and discrimination are major impediments to MAT enrollment, necessitating implementation of interventions to address them.

RESUMEN

HIV-positive people often experience mental health disorders and engage in substance use. Such conditions tend to impair their health-related quality of life (QOL). Evidence, however, is limited about the influence of mental health disorders and substance use on QOL by gender. Also, little is known about the influences of anxiety and high levels of stress on QOL. We recruited 682 HIV-positive people in Nepal and measured their depression, anxiety, stress levels, substance use, and QOL. Multiple linear regressions assessed the association of mental health disorders and substance use with QOL. Presence of depressive symptoms was negatively associated with all domains of QOL including the physical (men: ß = -0.68, p = 0.037; women: ß = -1.37, p < 0.001) and the psychological (men: ß = -1.08, p < 0.001; women: ß = -1.13, p < 0.001). Those who experienced anxiety had lower scores in the physical (ß = -0.89, p = 0.027) and psychological (ß = -1.75, p = 0.018) QOL domains among men and in the spiritual QOL domain (ß = -0.061, p = 0.043) among women. High stress levels were associated with lower scores across all QOL domains including the physical (men: ß = -0.16, p < 0.001; women: ß = -0.14, p < 0.001) and the psychological (men: ß = -0.09, p < 0.001; women: ß = -0.10, p < 0.001). Substance-using men were more likely to have lower scores in physical (ß = -0.70, p = 0.039) and psychological (ß = -0.073, p = 0.002) domains. Among women, meanwhile, substance use was negatively associated with the psychological domain only (ß = -0.77, p = 0.005). In conclusion, mental health disorders and substance use had negative associations with QOL. Attention should be given to addressing the mental health care needs of HIV-positive people to improve their QOL.

RESUMEN

BACKGROUND: Reports of frequent manifestation of allergic diseases in children with attention deficit hyperactivity disorder (ADHD) have been the subject of mounting clinical interest. However, evidence supporting the association between ADHD and allergies is inconsistent and has yet to be systematically reviewed. The objective of this study was to compile and assess available studies on the association between ADHD and allergic diseases in children. METHODS: A comprehensive search using MEDLINE, EMBASE, the Cochrane library, and CINAHL databases was completed in 23 November 2015. The inclusion criteria for studies were that the research assessed allergic diseases in children, 18 years of age and younger, with a diagnosis of ADHD and that a distinct comparison group was incorporated. Any comparative studies, encompassing both randomized controlled trials and observational studies, were considered for inclusion. Two review authors independently assessed the quality of the selected studies by the use of validated assessment tools, performed data extraction and conducted meta-analysis according to Cochrane Collaboration guidelines. RESULTS: Five eligible studies were included in this systematic review. Of these studies, three were case-control and two were cross sectional studies. A majority of information from the five studies was classified as having low or unclear risk of bias. The meta-analysis showed an association between children with ADHD and asthma compared with the control groups (OR: 1.80, 95% CI: 1.57 - 2.07; five studies, low quality of evidence), but did not indicate an association between food allergy and ADHD (OR: 1.13, 95% CI: 0.88 - 1.47; three studies very low quality of evidence). The odds of experiencing allergic rhinitis, atopic dermatitis, and allergic conjunctivitis were slightly higher in children with ADHD compared with control groups, though a substantial statistical heterogeneity was notable in the overall effect estimates. CONCLUSIONS: The findings from this review and meta-analysis show that children with ADHD are more likely to have asthma, allergic rhinitis, atopic dermatitis, and allergic conjunctivitis than their counterparts. Interventions including strategies for managing allergies in children with ADHD would be beneficial.

RESUMEN

BACKGROUND: Nutrition training can boost competence of health workers to improve children's feeding practices. In this way, child undernutrition can be ameliorated in general populations. However, evidence is lacking on efficacy of such interventions among Human Immunodeficiency Virus (HIV)-positive children. We aimed to examine the efficacy of a nutrition training intervention to improve midlevel providers' (MLPs) nutrition knowledge and feeding practices and the nutrition statuses of HIV-positive children in Tanga, Tanzania. METHODS: This cluster-randomized controlled trial was conducted in 16 out of 32 care and treatment centers (CTCs) in Tanga. Eight CTCs were assigned to the intervention arm and a total of 16 MLPs received nutrition training and provided nutrition counseling and care to caregivers of HIV-positive children. A total of 776 pairs of HIV-positive children and their caregivers were recruited, of whom 397 were in the intervention arm. Data were analyzed using instrumental variable random effects regression with panel data to examine the efficacy of the intervention on nutrition status through feeding practices. RESULTS: Mean nutrition knowledge scores were higher post-training compared to pre-training among MLPs (37.1 vs. 23.5, p < 0.001). A mean increment weight gain of 300 g was also observed at follow-up compared to baseline among children of the intervention arm. Feeding frequency and dietary diversity improved following the intervention and a 6 months follow-up (p < 0.001). An increase in each unit of feeding frequency and dietary diversity were associated with a 0.15-unit and a 0.16-unit respectively decrease in the child underweight (p < 0.001). CONCLUSIONS: Nutrition training improved nutrition knowledge among MLPs caring for HIV-positive children attending CTCs in Tanga, Tanzania. Caregivers' feeding practices also improved, which in turn led to a modest weight gain among HIV-positive children. To sustain weight gain, efforts should be made to also improve households' food security and caregivers' education in addition to inservice nutrition trainings. The protocol was registered on 15/02/2013, before the recruitment at ISRCTN trial registry with the trial registration number: ISRCTN65346364.

RESUMEN

UNLABELLED: Nutrition transition necessitates low and middle-income countries (LAMICs) to scale up their efforts in addressing the burdens of undernutrition and overweight/obesity. Magnitudes of undernutrition and overweight are high in LAMICs, but no study has reviewed the existence of nutrition policies to address it. No evidence is also available on the effect of nutrition policies and governance on the undernutrition and overweight/obesity patterns in such countries. We conducted a policy review to examine the presence and associations of nutrition policies and governance with the children's nutrition statuses in LAMICs. METHODS: We reviewed nutrition policies, nutrition governance, and the trends of nutrition status from LAMICs. We retrieved data on the policies from the global database on the implementation of nutrition actions (GINA). We also retrieved data on the trends of nutrition status and nutrition governance from the nutrition landscape information system (NLiS), and on LAMICs from the World Bank database. We then analyzed the data both descriptively and by using a mixed effects model with random-intercept by country. RESULTS: Of the 139 LAMICs reviewed, only 39.6% had policies to address both undernutrition and overweight/obesity. A higher proportion of low-income countries (LICs) had policies to address undernutrition compared to that of middle-income countries (MICs) (86.1% vs. 63.1%, p = 0.002), and a low proportion of both had policy to address overweight. Having a nutrition policy that addresses undernutrition was not associated with better nutrition status outcomes. Strong nutrition governance in LAMICS was associated with low magnitudes of stunting (beta = -4.958, p = 0.015); wasting (beta = -5.418, p = 0.003); and underweight (beta = -6.452, p = 0.001). CONCLUSION: Despite high magnitudes of undernutrition and overweight/obesity in LAMICs, only about one third of them had nutrition policies to address such nutrition transition. Having strong nutrition governance may help to bring down the magnitudes of undernutrition in LAMICs.

RESUMEN

OBJECTIVE: This study aimed to document lessons learnt and best practices for scaling up an innovative emergency transportation system, drawing insights from the m-mama programme implemented in Shinyanga, Tanzania. The m-mama pilot programme was implemented in phases from 2014 to 2016 in two districts and later scaled up to include all districts in Shinyanga region in 2017. The programme employed an emergency transportation system and technical and operational support of the health system to address the three delays leading to maternal and neonatal mortality. DESIGN: Cross-sectional, qualitative research with key healthcare system stakeholders from the national, regional and district levels. SETTING: The study was conducted in Kahama and Kishapu districts in Shinyanga, Tanzania. The two districts were selected purposefully to represent the programme implementation districts' rural and urban or semiurban settings. PARTICIPANTS: District, regional and national stakeholders involved in implementing the m-mama pilot programme in Shinyanga were interviewed between February and March 2022. RESULTS: Lessons learnt from implementing the m-mama programme were grouped into four key themes: community engagement, emergency transportation system, government engagement, and challenges and constraints in technical implementation. Stakeholder engagement and collaboration at all levels, community involvement in implementation, adherence to local contexts and effective government partnerships were identified as key drivers for programme success. Coordination, supervision and infrastructure enhancement were crucial in implementing the emergency transportation system. CONCLUSIONS: Facilitating community involvement, understanding the local context and adapting to existing structures can enhance programme ownership and utilisation. The government serves as the central coordinator, overseeing resource mobilisation and distribution. A well-executed and coordinated emergency transportation system holds promise in addressing delays and curbing maternal and neonatal mortality. Collaborative knowledge-sharing among implementers is essential for identifying best practices and gaining insights into practical strategies for addressing anticipated challenges.

RESUMEN

BACKGROUND: Nutrition training of health workers can help to reduce child undernutrition. Specifically, trained health workers might contribute to this end through frequent nutrition counseling of caregivers. This may improve child-feeding practices and thus reduce the risk of undernutrition among children of counseled caregivers. Although studies have shown varied impacts of health workers' nutrition training on child feeding practices, no systematic review of the effectiveness of such intervention has yet been reported. Therefore, we conducted this study to examine the effectiveness of nutrition training for health workers on child feeding practices including feeding frequency, energy intake, and dietary diversity among children aged six months to two years. METHODS: We searched the literature for published randomized controlled trials (RCTs) and cluster RCTs using medical databases including PubMed/MEDLINE, CINAHL, EMBASE, and ISI Web of Knowledge, and through WHO regional databases. Our intervention of interest was nutrition training of health workers. We pooled the results of the selected trials, evaluated them using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria, and calculated the overall effect size of the intervention in meta-analyses. RESULTS: Ten RCTs and cluster RCTs out of 4757 retrieved articles were eligible for final analyses. Overall, health workers' nutrition training improved daily energy intake of children between six months and two years of age. The pooled evidence from the three studies reporting mean energy intake per day revealed a standardized mean difference (SMD) of 0.76, 95% CI (0.63-0.88). For the two studies with median energy intake SMD was 1.06 (95% CI 0.87-1.24). Health workers' nutrition training also improved feeding frequency among children aged six months to two years. The pooled evidence from the three studies reporting mean feeding frequency showed an SMD of 0.48 (95% CI 0.38-0.58). Regarding dietary diversity, children in intervention groups were more likely to consume more diverse diets compared to their counterparts. CONCLUSION AND RECOMMENDATIONS: Nutrition training for health workers can improve feeding frequency, energy intake, and dietary diversity of children aged six months to two years. Scaling up of nutrition training for health workers presents a potential entry point to improve nutrition status among children.

RESUMEN

To meet lofty human papillomavirus (HPV) immunization goals in Tanzania, the Ministry of Health integrated HPV vaccination with adolescent health services using a school-based approach. A qualitative study was conducted in June-July 2021, examining the feasibility and sustainability of an integrated service package, HPV Plus. In-depth interviews with 46 programme implementers (i.e. health-care workers and teachers) and planning stakeholders (i.e. government officials and school administrators) in Dar es Salaam and Njombe Regions explored enablers and constraints to HPV Plus programme implementation, including resource and staffing requirements. Two facilitators and three barriers to HPV Plus feasibility and sustainability were identified from thematic analysis of interviews. Interviewed stakeholders emphasized the programme's feasibility, especially if the efficiencies offered by a school-based platform were optimized. Implementation facilitators included (1) optimized service delivery efficiency through a school-based platform and (2) resources saved by combining adolescent health services and HPV immunization into a single programme package. Key barriers to HPV Plus feasibility and sustainability were (1) time, space and resource constraints (e.g. commodity stockouts and challenges delivering the complete service package to large cohorts of students within allotted times); (2) human resource gaps and increased workloads within the health workforce and (3) insufficient referral mechanisms linking schools to health facilities. Scaling up HPV Plus will require proactive commodity procurement and security; resource mobilization to reach ambitious service delivery targets and close co-ordination of programme implementation with school administrators.

RESUMEN

In achieving the sustainable development goal 3.1, Tanzania needs substantial investment to address the three delays which responsible for most of maternal deaths. To this end, the government of Tanzania piloted a community-based emergency transport intervention to address the second delay through m-mama program. This study examined secondary data to determine the cost-effectiveness of this intervention in comparison to the standard ambulance system alone. The m-mama program was implemented in six councils of Shinyanga region. The m-mama program data analyzed included costs of referral services using the Emergency Transportation System (EmTS) compared with the standard ambulance system. Analysis was conducted using Microsoft Excel, whose data was fed into a TreeAge Pro Healthcare 2022 model. The cost and effectiveness data were discounted at 5% to make a fair comparison between the two systems. During m-mama program implementation a total of 989 referrals were completed. Of them, 30.1% used the standard referral system using ambulance, while 69.9% used the EmTS. The Emergency transport system costed USD 170.4 per a completed referral compared to USD 472 per one complete referral using ambulance system alone. The introduction of m-mama emergency transportation system is more cost effective compared to standard ambulance system alone in the context of Shinyanga region. Scaling up of similar intervention to other regions with similar context and burden of maternal mortality may save cost of otherwise normal emergency ambulance system. Through lessons learned while scaling up, the intervention may be improved and tailored to local challenges and further improve its effectiveness.

RESUMEN

Maternal mortality comprises about 10% of all deaths among women of reproductive age (15-49 years). More than 90% of such deaths occur in low- and middle-income countries (LMIC). In this study, we aimed to document lessons learnt and best practices toward sustainability of the m-mama program for reducing maternal and newborn mortality in Tanzania. We conducted a qualitative study from February to March 2022 in Kahama and Kishapu district councils of Shinyanga region. A total of 20 Key Informant Interviews (KII) and four Focused Group Discussions (FGDs) were conducted among key stakeholders. The participants included implementing partners and beneficiaries, Community Care groups (CCGs) facilitators, health facility staff, drivers and dispatchers. We gathered data on their experience with the program, services offered, and recommendations to improve program sustainability. We based the discussion of our findings on the integrated sustainability framework (ISF). Thematic analysis was conducted to summarize the results. To ensure the sustainability of the program, these were recommended. First, active involvement of the government to complement community efforts, through the provision and maintenance of resources including a timely and inclusive budget, dedicated staff, infrastructure development and maintenance. Secondly, support from different stakeholders through a well-coordinated partnership with the government and local facilities. Third, continued capacity building for implementers, health care workers (HCWs) and community health workers (CHWs) and community awareness to increase program trust and services utilization. Dissemination and sharing of evidence and lesson learnt from successful program activities and close monitoring of implemented activities is necessary to ensure smooth, well-coordinated delivery of proposed strategies. Considering the temporality of the external funding, for successful implementation of the program, we propose a package of three key actions; first, strengthening government ownership and engagement at an earlier stage, secondly, promoting community awareness and commitment and lastly, maintaining a well-coordinated multi-stakeholder' involvement during program implementation.

RESUMEN

Tanzania has one of the highest cervical cancer incidence and mortality rates in sub-Saharan Africa. The Tanzanian Ministry of Health developed an integrated adolescent health program, HPV-Plus, that combines HPV vaccination with additional health services: nutritional assessments, vision screening, and vaccination for adolescent girls, and education for all genders. This qualitative descriptive study evaluated the acceptability of the HPV-Plus program in two districts in Tanzania. Key informants comprising of adolescent girls, parents, program planners, and program implementers in Njombe and Dar es Salaam Tanzania were interviewed to assess the program acceptability. Transcripts were analyzed using a team-based iterative thematic analysis approach, consisting of both inductive and deductive coding. The Theoretical Framework of Acceptability was used to guide analysis, with themes categorized according to theoretical constructs of intervention coherence, affective attitudes and perceptions, and perceived effectiveness. Overall acceptability of the HPV-Plus program was high among stakeholders. The most salient finding regarding factors that influenced HPV vaccine acceptability was largely related to education and knowledge levels surrounding the HPV, cervical cancer, and HPV vaccines. The educational component of the HPV-Plus program was key in increasing acceptability. Parents reported the lowest acceptability towards the program. This was found to be primarily due to perceptions of not being sufficiently engaged throughout program implementation. Increasing acceptability of HPV vaccination programs among key stakeholders is critical to facilitating vaccine uptake and meeting vaccination coverage targets. Our results demonstrate that the inclusion of a comprehensive education component within the HPV-Plus program was key in facilitating HPV vaccine acceptability amongst stakeholders.

RESUMEN

INTRODUCTION: People who use drugs (PWUD) experience stigma from multiple sources due to their drug use. HIV seroprevalence for PWUD in Tanzania is estimated to range from 18 to 25%. So, many PWUD will also experience HIV stigma. Both HIV and drug use stigma have negative health and social outcomes, it is therefore important to measure their magnitude and impact. However, no contextually and linguistically adapted measures are available to assess either HIV or drug use stigma among PWUD in Tanzania. In response, we translated and culturally adapted HIV and drug use stigma measures among Tanzanian PWUD and described that process in this study. METHODS: This was a cross-sectional study. We translated and adapted existing validated stigma measures by following a modified version of Wild's ten steps for translation and adaptation. We also added new items on stigmatizing actions that were not included in the original measures. Following translation and back translation, we conducted 40 cognitive debriefs among 19 PWUD living with and 21 PWUD not living with HIV in Dar es Salaam to assess comprehension of the original and new items. For challenging items, we made adaptations and repeated cognitive debriefs among ten new PWUD participants where half of them were living with HIV. RESULTS: Most of the original items (42/54, 78%), response options and all items with new 12 stigmatizing actions were understood by participants. Challenges included response options for a few items; translation to Swahili; and differences in participants' interpretation of Swahili words. We made changes to these items and the final versions were understood by PWUD participants. CONCLUSION: Drug use and HIV stigma measures can successfully be translated and culturally adapted among Tanzanian PWUD living with and without HIV. We are currently conducting research to determine the stigma measures' psychometric properties and we will report the results separately.

RESUMEN

BACKGROUND: The emergence of HIV drug resistance mutations (DRMs) is of significant threat to achieving viral suppression (VS) in the quest to achieve global elimination targets. We hereby report virologic outcomes and patterns of acquired DRMs and its associated factors among adolescents and young adults (AYA) from a broader HIV drug resistance surveillance conducted in Tanzania. METHODS: Data of AYA was extracted from a cross-sectional study conducted in 36 selected facilities using a two-stage cluster sampling design. Dried blood spot (DBS) samples were collected and samples with a viral load (VL) ≥1000 copies/mL underwent genotyping for the HIV-1 pol gene. Stanford HIV database algorithm predicted acquired DRMs, Fisher's exact test and multivariable logistic regression assessed factors associated with DRMs and VS, respectively. FINDINGS: We analyzed data of 578 AYA on antiretroviral therapy (ART) for 9-15 and ≥ 36 months; among them, 91.5% and 88.2% had VS (VL<1000copies/mL) at early and late time points, respectively. Genotyping of 64 participants (11.2%) who had VL ≥1000 copies/ml detected 71.9% of any DRM. Clinically relevant DRMs were K103N, M184V, M41L, T215Y/F, L210W/L, K70R, D67N, L89V/T, G118R, E138K, T66A, T97A and unexpectedly absent K65R. Participants on a protease inhibitor (PI) based regimen were twice as likely to not achieve VS compared to those on integrase strand transfer inhibitors (INSTI). The initial VL done 6 months after ART initiation of ≥1000copies/mL was the primary factor associated with detecting DRMs (p = .019). CONCLUSIONS: VS amongst AYA is lower than the third UNAIDs target. Additionally, a high prevalence of ADR and high levels of circulating clinically relevant DRMs may compromise the long-term VS in AYA. Furthermore, the first VL result of ≥1000copies/ml after ART initiation is a significant risk factor for developing DRMs. Thus, strict VL monitoring for early identification of treatment failure and genotypic testing during any ART switch is recommended to improve treatment outcomes for AYA.
