Efficacy of mobile phone intervention to increase male partner antenatal care attendance for HIV testing in Moshi municipal, Tanzania: a randomized controlled trial

BACKGROUND

HIV partner counselling and testing in antenatal care (ANC) is a crucial strategy to raise the number of males who know their HIV status. However, in many settings like Tanzania, male involvement in antenatal care remains low, and there is a definite need for innovative strategies to increase male partner involvement. This study was designed to evaluate the efficacy of mobile phone intervention increase male partner ANC attendance for HIV testing in Moshi municipal, Tanzania.

METHODS

Between April and July 2022, we enrolled pregnant women presenting to a first ANC visit at Majengo and St. Joseph reproductive health facilities without their male partners. Eligible pregnant women were randomly assigned to invitation of their male partners either via phone calls, text messages from clinic staff and verbal invites from pregnant partners (intervention arm) or verbal invites only from the pregnant partners (control arm). Neither healthcare provider nor participant were blinded. The primary outcome was the proportion of male partners who attended ANC with their pregnant partners during a follow-up period of two consecutive visits. The secondary outcome measure was HIV testing among male partners following the invitation. Participants were analyzed as originally assigned (intention to treat).

RESULTS

A total of 350 pregnant women presenting to ANC for the first time were enrolled, with 175 women enrolled in each arm. The efficacy of male attendance with their pregnant women following the invitations was 83.4% (147/175) in the intervention arm and 46.3% (81/175) in the control arm. Overall, the results suggest a positive and statistically significant average treatment effect among men who received mobile phone intervention on ANC attendance. For the secondary outcome, the percent of male partners who accepted HIV counselling and testing was 99.3% (146/147) in the intervention arm and 93.8% (76/81) in the control arm. Married men were having higher odds of ANC attendance compared with single men (aOR:6.40(3.26-12.56), Males with multigravida women were having lower odds of ANC attendance compared with primigravida women (aOR:0.17(0.09-0.33).

CONCLUSION

The study demonstrates that supplementing verbal invitations with mobile phone calls and text messages from clinic staff can significantly increase male partner ANC attendance and HIV testing. This combined approach is recommended in improving ANC attendance and HIV testing of male partners who do not accompany their pregnant partners to antenatal clinics in the first visits.

Dental Caries in Children with Sickle Cell Disease and Its Association with the Use of Hydroxyurea and Penicillin Prophylaxis in Dar Es Salaam

Purpose

This comparative study sets out to report dental caries status among individuals with Sickle Cell Disease (HbSS) against those with sickle cell trait (HbSA) and those without the disease (HbAA) as controls. The study further assessed the impact of penicillin chemoprophylaxis and hydroxyurea use on dental caries among Sickle Cell Disease participants.

Methods

This was a comparative cross-sectional study in which 93 children aged 30 to 60 months were recruited. There were 60 participating children who had SCD (HbSS), 17 with SCD trait (HbAS) and 16 were without SCD or SC trait (HbAA). A questionnaire was used to record sociodemographic details including mean age in months and sex and on haemoglobin genotype for all the participants. Specifically, for the participants with HbSS, information on their whether they are taking hydroxyurea (HU), and penicillin chemoprophylaxis was recorded. To assess the prevalence of dental caries, clinical examination of all primary maxillary and mandibular teeth to determine the presence or absence of dental caries lesions was also recorded.

Results

A total of 1197 teeth from 93 children were examined, whereby, 45 (2.4%) of them had dental caries. The participating children with HbAA genotype (6.6%, N=21) had more dental caries than their HbSS counterparts (2.0%, N=24), while none of the participants with HbAS exhibited dental caries. Among the participants with HbSS, males and those who use HU were 3.79 and 3.07 times more likely to have dental caries than their counterparts, female and non-users of HU, respectively.

Conclusion

Dental caries was observed to be low among participants with HbSS when compared to those with HbAA. More research utilizing more robust methodologies is recommended.

National Non-Communicable Diseases Conferences- A Platform to Inform Policies and Practices in Tanzania

Background

Non-communicable diseases (NCDs) arise from diverse risk factors with differences in the contexts and variabilities in regions and countries. Addressing such a complex challenge requires local evidence. Tanzania has been convening stakeholders every year to disseminate and discuss scientific evidence, policies, and implementation gaps, to inform policy makers in NCDs responses. This paper documents these dissemination efforts and how they have influenced NCDs response and landscape in Tanzania and the region.

Methods

Desk review was conducted through available MOH and conference organizers' documents. It had both quantitative and qualitative data. The review included reports of the four NCDs conferences, conference organization, and conduct processes. In addition, themes of the conferences, submitted abstracts, and presentations were reviewed. Narrative synthesis was conducted to address the objectives. Recommendations emanated from the conference and policy uptake were reviewed and discussed to determine the impact of the dissemination.

Findings

Since 2019, four theme-specific conferences were organized. This report includes evidence from four conferences. The conferences convened researchers and scientists from research and training institutions, implementers, government agencies, and legislators in Tanzania and other countries within and outside Africa. Four hundred and thirty-five abstracts were presented covering 14 sub-themes on health system improvements, financing, governance, prevention intervention, and the role of innovation and technology. The conferences have had a positive effect on governments' response to NCDs, including health care financing, NCDs research agenda, and universal health coverage.

Conclusion

The National NCDs conferences have provided suitable platforms where stakeholders can share, discuss, and recommend vital strategies for addressing the burden of NCDs through informing policies and practices. Ensuring the engagement of the right stakeholders, as well as the uptake and utilization of the recommendations from these platforms, remains crucial for addressing the observed epidemiological transition in Tanzania and other countries with similar contexts.

Type 2 Diabetes Mellitus in Tanzania. A Narrative Review of Epidemiology and Disease Trend

INTRODUCTION

The prevalence of type 2 diabetes is on a rapid rise in Tanzania, driven by lifestyle modifications, nutritional changes, and increased obesity rates. This article reviews the epidemiology, and disease trends of type 2 diabetes in Tanzania and explores the economic implications and challenges in care, including policy, education, and healthcare systems.

METHODOLOGY

The study employs a narrative literature review from research articles, local healthcare reports, surveys, and public health records. It evaluates the economic impacts, healthcare capabilities, and patient behaviors in managing type 2 diabetes in Tanzania.

RESULTS

The economic burden of diabetes in Tanzania is increasing due to direct healthcare costs, lost productivity, and reduced quality of life, placing significant pressure on the already resourcelimited healthcare system. Treatment dropout rates are alarmingly high, and healthcare providers' knowledge of diabetes is insufficient. Insulin and metformin availability are critically low. Cultural norms and dietary habits pose substantial barriers to effective disease management.

CONCLUSION

The growing prevalence of type 2 diabetes in Tanzania presents a significant public health crisis, necessitating comprehensive strategies for prevention, early detection, and effective disease management. Priorities should include enhancing healthcare infrastructure, increasing public investment, improving healthcare education, and tackling socio-cultural barriers to disease management.

Non-communicable Diseases Week: Best Practices in Addressing the NCDs Burden from Tanzania

Background

Five million people die every year from non-communicable diseases (NCDs) globally. In Tanzania, more than two-thirds of deaths are NCD-related. The country is investing in preventive and advocacy activities as well as interventions to reduce the burden. Of particular interest, the Ministry of Health (MoH) commemorates NCDs' week using a multisectoral and multi-stakeholders' approach. This paper highlights activities conducted during NCDs week with the aim of sharing lessons for other countries with similar context and burdens.

Methods

A thorough review of official reports and the national strategic plans for NCDs was done including the 2020 and 2021 National NCDs' week reports, the National Strategic Plan for NCDs 2015-2020, and the National NCDs agenda.

Findings

NCDs week is commemorated annually throughout the country involving the five key activities. First, community awareness and participation are encouraged through media engagement and community-based preventive and advocacy activities. Second, physical activities and sports festivals are implemented with a focus on developing and renovating infrastructures for sports and recreation. Third, health education is provided in schools to promote healthy behaviors for secondary school adolescents in transition to adulthood. Fourth, health service provision and exhibitions are conducted involving screening for hypertension, diabetes, obesity, alcohol use, and physical activities. The targeted screening of NCDs identified 10% of individuals with at least one NCD in 2020. In 2021, a third of all screened individuals were newly diagnosed with hypertension, and 3% were found to have raised blood glucose levels. Fifth, the national NCDs scientific conferences conducted within the NCDs week provide an avenue for stakeholders to discuss scientific evidence related to NCDs and recommend strategies to mitigate NCDs burden.

Conclusion

The initiation of NCDs week has been a cornerstone in advocating for NCDs control and prevention in the country. It has created awareness on NCDs, encourage healthy lifestyles and regular screening for NCDs. The multi-stakeholder and multi-sectoral approaches have made the implementation of the mentioned activities feasible and impactful. This has set an example for the united efforts toward NCD control and prevention at national, regional, and global platforms while considering contextual factors during adoption and implementation.

Mitigating the Rising Burden of Non-Communicable Diseases through Locally Generated Evidence-Lessons from Tanzania

Background

The burden of Non-Communicable Diseases (NCDs) is rapidly increasing globally, and low- and middle-income countries (LMICs) bear the brunt of it. Tanzania is no exception. Addressing the rising burden of NCDs in this context calls for renewed efforts and commitment by various stakeholders. This paper highlights local initiatives and strategies to combat NCDs in Tanzania and provides lessons for countries with similar contexts.

Methods

We reviewed published and grey literature and conducted policy analysis on NCDs in Tanzania to examine the burden of NCDs and the national response addressing it. The documents included National NCD strategic plans, NCD research agenda, and reports from the World Diabetes Foundation and the World Health Organization. Moreover, a scoping review of ongoing NCD activities and programs in other countries was also conducted to supplement the evidence gathered.

Results

The rising burden of NCDs as a result of the epidemiological transition in Tanzania called for the launching of a dedicated National NCD Control and Prevention Program. The Ministry of Health collaborates with local, national, and international partners on NCD prevention and curative strategies. This led to the development of important guidelines and policies on NCDs, including strengthening the capacity of health facilities and healthcare workers, increased community engagement and awareness of NCDs, and increased advocacy for more resources in NCD initiatives. Strong governmental commitment has been vital; this is demonstrated by a renewed commitment to the fight through national NCD week and related advocacy activities conducted annually. To ensure multi-stakeholders' engagement and political commitment, all these activities are coordinated at the Prime Minister's office and provide strong lessons for countries with contexts similar to Tanzania.

Conclusion

Multi-stakeholders' engagement, innovative approaches, and coordinated governmental efforts to address NCDs have shone a light on addressing the burden of NCDs and may be sustainable if aligned with locally available resources. Such initiatives are recommended for adoption by other nations to address the burdens of NCDs.

Improved Biorepository to Support Sickle Cell Disease Genomics and Clinical Research: A Practical Approach to Link Patient Data and Biospecimens from Muhimbili Sickle Cell Program, Tanzania

In Africa, sickle cell disease phenotypes' genetic contributors remain understudied due to the dearth of databases that pair biospecimens with demographic and clinical details. The absence of biorepositories in these settings can exacerbate this issue. This article documents the physical verification process of biospecimens in the biorepository, connecting them to patient clinical and demographic data and aiding in the planning of future genomic and clinical research studies' experience from the Muhimbili Sickle Cell Program in Dar es Salaam, Tanzania. The biospecimen database was updated with the current biospecimen position following the physical verification and then mapping this information to its demographic and clinical data using demographic identifiers. The biorepository stored 74,079 biospecimens in three -80°C freezers, including 63,345 from 5159 patients enrolled in the cohort between 2004 and 2016. Patients were identified by a control (first visit), entry (when confirmed sickle cell homozygous), admission (when hospitalized), and follow-up numbers (subsequent visits). Of 63,345 biospecimens, follow-ups were 46,915 (74.06%), control 8067 (12.74%), admission 5517 (8.71%), and entry 2846 (4.49%). Of these registered patients, females were 2521 (48.87%) and males were 2638 (51.13%). The age distribution was 1-59 years, with those older than 18 years being 577 (11.18%) and children 4582 (88.82%) of registered patients. The notable findings during the process include a lack of automated biospecimen checks, laboratory information management system, and tubes with volume calibration; this caused the verification process to be tedious and manual. Biospecimens not linked to clinical and demographic data, date format inconsistencies, and lack of regular updating of a database on exhausted biospecimens and updates when biospecimens are moved between positions within freezers were other findings that were found. A well-organized biorepository plays a crucial role in answering future research questions. Enforcing standard operating procedures and quality control will ensure that laboratory users adhere to the best biospecimen management procedures.

Current challenges and new approaches to implementing optimal management of sickle cell disease in sub-Saharan Africa

Sickle cell disease (SCD) is the most common life-threatening monogenic disorder in the world. The disease is highly prevalent in malaria endemic areas with over 75% of patients residing in Sub-Saharan Africa (SSA). It is estimated that, without proper care, up to 90% of children with SCD will not celebrate their fifth birthday. Early identification and enrolment into comprehensive care has been shown to reduce the morbidity and mortality related with SCD complications. However, due to resource constraints, the SSA is yet to implement universal newborn screening programs for SCD. Furthermore, care for patients with SCD in the region is hampered by the shortage of qualified healthcare workers, lack of guidelines for the clinical management of SCD, limited infrastructure for inpatient and outpatient care, and limited access to blood and disease modifying drugs such as Hydroxyurea which contribute to poor clinical outcomes. Curative options such as bone marrow transplant and gene therapy are expensive and not available in many SSA countries. In addressing these challenges, various initiatives are ongoing in SSA which aim to enhance awareness on SCD, improve patient identification and retention to care, harmonize the standards of care for SCD, improve the skills of healthcare workers and conduct research on pertinent areas in SCD in the SSA context. Fortifying these measures is paramount to improving the outcomes of SCD in SSA.

Metabolic syndrome among people living with HIV on antiretroviral therapy in Mwanza, Tanzania

BACKGROUND

HIV and antiretroviral drugs, particularly protease inhibitors and nucleoside reverse transcriptase inhibitors, may increase the risk of Metabolic Syndrome (MetS) among people living with HIV (PLHIV). However, following the introduction of better drugs like dolutegravir, data on the burden of MetS are limited. This study aimed to assess the prevalence of MetS and associated factors among PLHIV on antiretroviral therapy (ART) in Tanzania.

METHODS

This was a cross-sectional study among PLHIV aged ≥ 18 years on antiretroviral therapy for ≥ 1 year at Bugando Medical Centre in Mwanza conducted in 2020. Demographic and healthy-lifestyle-related non-communicable disease risk factors data were collected. Additionally, data on lipid profile, blood glucose, blood pressure, and waist circumference were collected for analysis of MetS according to the International Diabetes Federation criteria. Factors associated with MetS were assessed using logistic regression. A P ≤ 0.05 was considered statistically significant.

RESULTS

Data for 223 participants were analyzed. The mean (SD) age was 44 (± 12) years and 79.8% (178) were females. A majority 78% (174) were on a tenofovir, lamivudine,and dolutegravir regimen. About 12.1% (27) were either current or past smokers, 45.3% (101) were past alcohol drinkers, 22.9% (51) were current drinkers, 12.1% (27) reported taking ≥ 5 servings of vegetables and fruits per day and 5.8% (13) were physically inactive. The prevalence of MetS was 22.9%. The only factors that were associated with Mets were fat mass index and adequate intake of vegetables and fruits, (adjusted odds ratio (aOR) 2.9, 95% CI 1.0, 7.9, P = 0.04) and (aOR1.2, 95% CI 1.0, 1.3, P = 0.02), respectively).

CONCLUSION

The prevalence of MetS remains high among PLHIV. Adiposity and adequate fruit and vegetable intake increased the risk. The introduction of new ART regimens shows no effect on MetS prevalence. Research is needed to understand how lifestyle changes could reduce MetS in PLHIV.

Failure to Attain HIV Viral Suppression After Intensified Adherence Counselling-What Can We Learn About Its Factors?

Background

Introduction and expansion of antiretroviral therapy (ART) have turned the tide of HIV pandemic, thus helping people living with HIV (PLHIV) achieve viral suppression. This success may need to be complemented by intensified adherence counseling (IAC) to improve adherence to treatment. However, some PLHIV still face higher than acceptable viral loads despite being on treatment.

Purpose

We investigated the factors associated with the failure to suppress HIV viral load after three months of IAC sessions.

Patients and Methods

This cross-sectional study analyzed secondary data from PLHIV-attended care and treatment clinics in Mwanza between January 2018 and December 2019 who had unsuppressed VL after being on ART for at least six months. We identified PLHIV in first-line ART with viral load evaluation before receiving IAC and had viral load results done at 90 days after IAC. We conducted descriptive statistics to examine the magnitude of viral suppression. Wilcoxon signed-rank test used to compare the median viral load before and after IAC sessions, and logistic regressions predicted the factors associated with failure.

Results

This study included 212 subjects. After intervention, most participants 85.9% (182) had significantly improved adherence compared to baseline. More than half 75.5% (160) of the participants had viral suppression after the intervention. Participants aged 18-25 years (AOR = 5.6, 95% CI, 1.1-29.6), unstable client during ART initiation (AOR = 0.3, 95% CI, 0.13-0.62), and poor adherence to ART (AOR = 4, 95% CI, 1.3-12.3) remained the main predictors of virological failure after IAC intervention.

Conclusion

Even though virological suppression is influenced by ART adherence, the findings in this study have shown co-existence of other factors to be addressed. Unstable during ART initiation is a new factor identified in this study.

Outcomes of Hydroxyurea Accessed via Various Means and Barriers Affecting Its Usage Among Children with Sickle Cell Anaemia in North-Western Tanzania

Purpose

To assess clinical and haematological outcomes of Hydroxyurea accessed via various access means and uncover the barriers to its utilization in children with Sickle cell anaemia (SCA), North-western Tanzania.

Patients and Methods

A retrospective study was conducted between October 2020 and April 2021 at Bugando Medical Centre (BMC) through review of medical files to compare the clinical and haematological outcomes among children with SCA at baseline and followed up retrospectively for at least one year of hydroxyurea utilization, accessed via cash, insurance and projects. Subsequently, a cross-sectional survey was conducted among parents and caregivers to ascertain the barriers to access of hydroxyurea via the various means. The p-values <0.05 were considered statistically significant.

Results

We identified 87 children with SCA who were on hydroxyurea for at least one year. The median age at baseline (before hydroxyurea) was 99 [78-151] months, and 52/87 (59.8%) were male. Compared to baseline, there was a significant reduction in proportion of patients reporting vaso-occlusive crisis, admissions and blood transfusions, a significant increase in Haemoglobin and mean corpuscular volume, conversely a significant reduction in absolute neutrophil and reticulocytes to both insurance and project participants. There was no significant change in most of these parameters among patients who accessed hydroxyurea via cash. Further, a total of 24/87 (27.6%) participants reported different barriers to access of hydroxyurea, where 10/24 (41.7%) reported hydroxyurea to be very expensive, 10/24 (41.7%) reported insurance challenges, and 4/21 (16.6%) reported unavailability of the drug.

Conclusion

The paediatric patients utilizing hydroxyurea accessed via insurance and projects, but not cash, experienced significant improvement in the clinical and haematological outcomes. Several barriers for access to hydroxyurea were observed which appeared to impact these outcomes. These findings call for concerted efforts to improve the sustainable access to hydroxyurea among all patients with SCA.

The efficacy of maternal health education and maternal screening on knowledge and the uptake of infant screening for sickle cell disease in Dar-Es-Salaam, Tanzania; a quasi experimental study

BACKGROUND

Globally, Sickle cell disease (SCD) is one of the most common genetic disease with high childhood mortality. Early identification of babies with SCD through newborn screening (NBS) and linking them to care are among the recommended interventions. The purpose of this study was to assess the efficacy of maternal health education and maternal screening for SCD on knowledge and the uptake of infant screening for SCD among mother-infant pairs attending antenatal clinics at Government health facilities in Dar-es-salaam, Tanzania.  METHODS: This study was a pre-test post-test, quasi-experimental which involved pregnant women attending antenatal clinics at three hospitals; Mbagala hospital, Sinza hospital and Buguruni health center in Dar Es Salaam. A structured questionnaire was used in data collection. Knowledge on SCD was assessed for all participants before and after two sessions of health education. Participants in Mbagala and Buguruni were also screened for SCD using Sickle SCAN point-of-care test (BioMedomics Inc, USA). The efficacy for health education intervention was computed as the post-intervention minus baseline knowledge score. For proportions, a two-sample z-test was used. Univariate and multivariate logistic regression were used to analyze the efficacy of health education intervention and also predictors of infant diagnosis.  RESULTS: For two sessions of health education intervention, a total of 467 pregnant women completed the sessions. During antenatal visits, a total of 218 were screened for SCD. The proportion of participants with good knowledge of SCD had significantly increased to 85.9% from 12.4% at baseline following the education intervention. In multivariate analysis, sharing the received education on SCD was an independent predictor of the efficacy of health education intervention. Maternal occupation, maternal SCD status as well as sharing the received education on SCD were independent predictors of the uptake of SCD infant diagnosis.

CONCLUSION

This study has demonstrated that maternal health education and maternal screening for SCD are feasible and efficacious interventions in raising knowledge and improving the uptake of infant diagnosis for SCD. These interventions are strongly recommended to be included in the comprehensive care package for pregnant women attending antenatal clinics, particularly in areas with a high burden of SCD.

Cervical cancer in Northern Tanzania-What do women living with HIV know

Background

Cervical cancer (CC) is more prevalent in women living with human immunodeficiency virus (HIV) infection compared to the general population. The magnitude is high among all countries burdened with HIV-Tanzania is no exception. Despite the unprecedented risk, women living with HIV (WLHIV) may not be aware of the risk and might have unfounded beliefs thereof. This study aimed to determine the knowledge, awareness, and beliefs on CC screening among WLHIV attending a clinic at the Kilimanjaro Christian Medical Centre (KCMC) in Northern Tanzania.

Methods

This hospital-based cross-sectional study was conducted among 327 WLHIV attending care and treatment clinic (CTC) at KCMC. A pre-tested questionnaire was used to collect quantitative data. Both descriptive and regression methods were used to determine CC knowledge, awareness, and beliefs as well as factors associated with knowledge of CC among WLHIV using SPSS version 23.

Results

Participants' mean age was 46 ± 10.4 years. Although just half (54.7%) of WLHIV had insufficient knowledge of CC, the majority of the participants (83.5%) were able to recognize at least three risk factors, but with limited understanding of symptoms and prevention. The majority held positive beliefs on CC and screening practices. Factors associated with good knowledge of CC included being married (AOR: 3.66, 95% CI: 1.84-7.28), having used ART for at least 2 years (AOR: 4.08, 95% CI: 1.36-12.21), and having previously screened for CC (AOR: 1.62, 95% CI: 1.01-2.59).

Conclusion

WLHIV attending care and treatment center had insufficient knowledge about CC screening. To further improve screening and treatment for CC, at both facility and community levels, targeted awareness and education campaigns are warranted.

Burden of active pulmonary tuberculosis among patients with diabetes in Dar es Salaam, Tanzania: a cross-sectional study

OBJECTIVES

We aimed to determine the prevalence, associated factors and describe the chest radiographic findings for active pulmonary tuberculosis (TB) among patients with diabetes mellitus (DM) attending a diabetic clinic in Tanzania.

DESIGN

Cross-sectional study.

SETTING

A diabetic clinic at Temeke Regional Referral Hospital in Dar es salaam, Tanzania.

PARTICIPANTS

Patients with diabetes.

MAIN OUTCOME MEASURES

The prevalence and factors associated with active TB in patients with DM.

RESULTS

Among 623 patients with DM screened, 11 (1.8%); 95% CI 0.9 to 3.1, had active TB of which 6 (54.5%) were GeneXpert positive and 5 (45.5%) were diagnosed based on clinical symptoms and suggestive chest radiographs. The risk of active TB was lower in patients aged 45-64 years compared with age below 45 years (adjusted prevalence ratio (aPR) 0.39, 95% CI (0.11 to 0.42), p=0.001) and in patients with normal chest examination findings compared with patients with crackles or bronchial breathing sounds (aPR 0.02, 95% CI (0.01 to 0.15), p<0.01). The predominant chest radiographic findings were opacification 100% mainly in the upper and mid-lung zones.

CONCLUSION

Diabetics should be screened for pulmonary TB, particularly among individuals aged 45 years and below with crackles or bronchial breathing on auscultation of the chest. High index of suspicion could help in the early detection and control of TB.

Barriers and Facilitators of Availability of Hydroxyurea for Sickle Cell Disease in Tanzania; A Qualitative Study of Pharmaceutical Manufacturers, Importers, and Regulators

Despite three decades of proven safety and effectiveness of hydroxyurea in modifying sickle cell disease (SCD), its accessibility is limited in Sub-Saharan Africa, which shares 75% of the world's SCD burden. Therefore, it is time to explore the barriers and facilitators for manufacturing and importation of hydroxyurea for SCD in Tanzania. This was qualitative research that employed a case study approach. Purposive sampling followed by an in-depth interview (IDI) using a semi-structured questionnaire aspired by data saturation enabled us to gather data from 10 participants. The study participants were people with more than three years of experience in pharmaceuticals importation, manufacturing, and regulation. The audio-recorded data were verbatim transcribed and analyzed using thematic analysis. Two themes were generated. The first comprised barriers for importation and manufacturing of hydroxyurea with sub-themes such as inadequate awareness of SCD and hydroxyurea, limited market, and investment viability. The second comprised opportunities for importation and manufacturing of hydroxyurea with sub-themes such as awareness of activities performed by medicines regulatory authority and basic knowledge on SCD and hydroxyurea. Inadequate understanding of SCD, hydroxyurea, and orphan drug regulation are major issues that aggravate the concern for limited market and investment viability. Existing opportunities are a starting point towards increasing the availability of hydroxyurea.

Using Evidence-Based Pedagogical Approaches to Pivot from In-Person to Online Training in a D43 Program during the COVID-19 Pandemic

The COVID-19 pandemic caused significant disruption to medical education globally. Fogarty International Center (FIC) training programs, designed to strengthen research capacity in low- and middle-income countries (LMICs), through partnerships between United States and LMIC institutions were particularly vulnerable to COVID-19 disruptions. We adapted short-term training for our FIC HIV Patient-Centered Outcomes Research program in Tanzania to the virtual environment using synchronous, asynchronous, and blended approaches and a variety of teaching pedagogies. We evaluated the acceptability and effectiveness of the new trainings among trainees and facilitators using a mixed-methods approach. Ninety percent of trainees and Muhimbili University of Health and Allied Sciences (MUHAS) facilitators agreed that the virtual training methods used were effective. Trainees reported high levels of satisfaction with the technology, group work, and relevance to their research. More than 50% of trainees and MUHAS facilitators agreed that learning in the virtual environment was as effective as, or more effective than, traditional in-person learning. However, they desired more interaction, opportunities to ask U.S. facilitators questions, and choices about topics for online versus in-person trainings. Two-thirds of U.S. facilitators agreed that the virtual delivery method was an effective way for participants to learn the material, although they also rated interaction less favorably. Virtual training incorporating pedagogical best practices of blended learning and traditional teaching online was a feasible, acceptable, and effective way of conducting research training to junior scientists during COVID-19. Virtual learning could become an integral part of post-pandemic training with some adaptation to improve interactions.

Nasopharyngeal Carriage and Antibiogram of Pneumococcal and Other Bacterial Pathogens from Children with Sickle Cell Disease in Tanzania

Background

Bacterial infections contribute significantly to morbidity and mortality in sickle cell disease (SCD) patients, particularly children under five years of age. In Tanzania, prophylaxis against pneumococcal infection among children with SCD advocates the use of both oral penicillin V (PV) and pneumococcal vaccines (PNV). Therefore, this study aimed to investigate nasopharyngeal carriage and antibiogram of Streptococcal pneumoniae (S. pneumoniae) and Staphylococcus aureus (S. aureus) in children with SCD in Tanzania.

Methods

This cross-sectional study was undertaken at the two Sickle Pan-African Research Consortium (SPARCO) study sites in Dar es salaam, Tanzania. The study was conducted for six months and enrolled children with SCD between the ages of 6 to 59-months. A semi-structured questionnaire was used to collect patient data. Nasopharyngeal swabs were collected from all participants and cultured for Streptococcal pneumoniae and other bacterial isolates. Antimicrobial susceptibility tests of the isolates were done using the disc diffusion method.

Results

Out of 204 participants, the overall prevalence of bacterial carriage was 53.4%, with S. aureus (23.5%), coagulase-negative Staphylococci (CoNS) (23%) and S. pneumoniae (7.8%) being commonly isolated. In antibiotic susceptibility testing, S. aureus isolates were most resistant to penicillin (81.8%), whereas 81.3% of S. pneumoniae isolates were resistant to co-trimoxazole. The least antimicrobial resistance was observed for chloramphenicol for both S. aureus and S. pneumoniae isolates (6.3% versus 0%). The proportion of multi-drug resistance (MDR) was 66.7% for S. aureus isolates and 25% for S. pneumoniae isolates.

Conclusion

There are substantially high nasopharyngeal carriage pathogenic bacteria in children with SCD in Dar es Salaam, Tanzania. The presence of MDR strains to the commonly used antibiotics suggests the need to reconsider optimizing antimicrobial prophylaxis in children with SCD and advocacy on pneumococcal vaccines.

Oxygen Saturation in Primary Teeth of Individuals With Sickle Cell Disease and Sickle Cell Trait

Purpose

To determine oxygen saturation in the pulp of primary teeth in children with sickle cell disease (SCD) and sickle cell trait (SCT) for establishing the usefulness of pulse oximetry in screening and monitoring of SCD or therapy.

Materials and Methods

A cross-sectional study among 30-60 months children with sickle cell disease (SCD) and sickle cell trait (SCT) compared with healthy children (HbAA). A pulse oximeter (BCI 3301) recorded oxygen saturation on six anterior primary maxillary teeth and on index fingers. Data were analyzed using SPSS version 20.0. Mean oxygen saturation for teeth and fingers was calculated. Comparison of Mean across groups was done using post hoc analysis in one-way ANOVA (Bonferroni test). Pearson correlation coefficient was calculated for mean oxygen saturation on fingers and teeth. Level of significance was set at 0.05.

Results

Altogether 360, 102, and 96 teeth were examined from children with SCD, SCT, and HbAA respectively. 53% of participants were girls. The mean age of participants was 46.3 months ± 9.4 SD. Low mean oxygen saturation (77.5%) was recorded from teeth of children with SCD relative to those with SCT and HbAA (>86%; P = 0.00). There was no statistically significant difference in oxygen saturation on teeth between children with SCT and HbAA. The mean oxygen saturation on fingers was found to be above 97.2% regardless of sickle cell status. There was no correlation between oxygen saturation on teeth and fingers.

Conclusion

Pulse oximeter detected a lower oxygen saturation in dental pulp of primary teeth of participants with SCD (HbSS) relative to those with SCT (HbAS) and HbAA. Oxygen saturation on fingers remained unaffected regardless of sickle cell disease status. Although more studies are needed, our study shows that when other conditions affecting peripheral tissue oxygen delivery are ruled out, the low pulse oximetry in primary teeth may be indicative of SCD. The oximeter may also be useful in monitoring response to SCD therapy targeted at improving oxygen carrying capacity and delivery.

Promoting access of hydroxyurea to sickle cell disease individuals: Time to make it an essential medicine

Hydroxyurea (HU) alone has the potential to prevent one out of every three deaths due to sickle cell disease (SCD) and almost all forms of disabilities caused by SCD. However, in Tanzania, only one out of every six registered SCD patients in the SPARCO-Tanzania Sickle Cell Cohort use HU. We conducted studies to understand factors influencing utilization of HU in Tanzania and discovered that among the reason for low utilization of HU include HU is classified as anticancer medication, only hematologists are supposed to prescribe HU, limited HU prescription to only National and Specialized hospitals, a special permit is required to access HU using National Health Insurance Fund (NHIF) scheme and limited importation and absence of local manufacturing of HU limit availability of this important drug in Tanzania. Therefore, with this brief, the government should allow prescription of HU to the district hospitals level, should allow all clinicians with a minimum of a Bachelor of Medicine to prescribe HU, and accessibility of HU through NHIF should be friendly.

The magnitude of type 2 diabetes mellitus and cardiovascular disease risk factors among young adults in urban settings: a cross-sectional survey in Mwanza, Tanzania

Introduction

traditionally, non-communicable diseases were diseases of public health concern in developed countries. Due to economic transition, they are becoming more prevalent in low and middle-income countries. Despite the trend, little has been done in the population of young adults of developing countries. This research aimed to explore the magnitude of type 2 diabetes mellitus, hypertension, dyslipidemia, and abdominal obesity among the young adult population in an urban setting of Tanzania.

Methods

the current research used a cross-sectional community-based design, involving apparently healthy young adults aged 18 to 34 years, not known to have diabetes, hypertension, or dyslipidemia. Data on socio-demographic characteristics, medical history, anthropometry, blood pressure, and lipids were obtained per standard operating procedures and analyzed using STATA 13. Association between outcome variables (type 2 diabetes mellitus, hypertension, dyslipidemia, and abdominal obesity) and predictor variables (age, sex, education level, occupation, and economic status) were assessed by logistic regression.

Results

245 young adults with a median age of 21 (interquartile range [IQR]: 18-25) were recruited. Prevalence of diabetes mellitus and of impaired glucose tolerance (IGT) were 7.8% and 15.5% respectively. Abdominal obesity and dyslipidemia were present in 11.8% and 45.1% respectively. 34.3% had hypertension and the risk was significantly higher in males compared to females (OR 1.8, 95%CI 1.1, 3.1). The atherogenic coefficient was significantly associated with abdominal obesity; other atherogenic indices did not show significant associations with current disease conditions.

Conclusion

alarmingly high prevalence of diabetes mellitus, impaired glucose tolerance, hypertension, abdominal obesity, and dyslipidemia were observed among young adults in Mwanza. This study highlights the need for concerted efforts for interventions targeting young adults in combating diabetes and cardiovascular disease (CVD) risk factors in Tanzania.

Joint Research Mentoring Through the Community of Young Research Peers: A Case for a Unifying Model for Research Mentorship at Higher Learning Institutions

BACKGROUND

Mentorship is pivotal for sustainability of a successful research culture at higher learning institutions. Various models have been proposed for provision of research mentorship in health sciences but are challenged by utilizing predominantly hierarchical mentoring, as well as being centred on one discipline or one institution. This paper describes the approach and successes of an inclusive mentorship model employed in a resource-limited setting in sub-Saharan Africa.

METHODS

Through the NIH-funded Transforming Health Professions Education in Tanzania (THET) project, a consortium of three prominent health sciences higher learning institutions in Tanzania (MUHAS, CUHAS and KCMUCo) and two collaborating US institutions (UCSF and Duke University) was formed. Within THET, the Community of Young Research Peers (CYRP) was constituted, comprised two cohorts of undergraduate students and young faculty (fellows), and senior scientists. Besides mentorship and research training, fellows received funded research awards and in turn mentored undergraduate students.

RESULTS

By the first quarter of project year four, the number of fellows and mentored undergraduate students had increased from 12 to 24 and from 41 to 67, respectively. Fellows in the second cohort (junior fellows) included medical doctors, nurses, dentist, biomedical scientist, sociologist and education psychologist. In fostering peer-to-peer mentoring, the cross-institutional pairs of fellows from the first cohort (senior fellows) were assigned to reciprocal pairs of junior fellow mentees and took a leading role in research training. Furthermore, the senior fellows had made significant strides, including eight enrolled in PhD programmes, eight publications from mentored research projects, and six small to medium-size research grants won.

CONCLUSION

The unifying model of research mentorship employed by the CYRP has been demonstrated as an effective model for joint research mentorship of the diverse group of young investigators from collaborating higher learning institutions in Tanzania. This model is recommended for scale-up, particularly in sub-Saharan Africa.

Prevalence of Hemoglobin-S and Baseline Level of Knowledge on Sickle Cell Disease Among Pregnant Women Attending Antenatal Clinics in Dar-Es-Salaam, Tanzania

Background: Sickle cell disease (SCD) is the single most important genetic cause of childhood mortality globally. Newborn screening (NBS) is the recommended intervention aimed at early identification of babies with SCD and their linkage to care. To ensure success of NBS, pregnant women need to have the required knowledge on SCD and therefore motivation to screen their babies. Objective: The aim of this study was to determine the prevalence of hemoglobin-S and assess the baseline level of knowledge on SCD among pregnant women attending antenatal clinics in urban settings in Dar-es-Salaam, Tanzania. Methods: This cross-sectional study was conducted between August 2020 and February 2021, involving 600 pregnant women at 20-28 weeks of gestation attending antenatal clinics at Buguruni Health Center, Mbagala Hospital, and Sinza Hospital in Dar-es-Salaam, Tanzania. We administered a structured questionnaire to all participants to assess socio-demographic characteristics and baseline level of knowledge on SCD, where those scoring 7 or higher out of 10 questions were considered to have good knowledge. We screened for SCD a total of 300 participants from two centers (Buguruni Health Center and Mbagala Hospital) by using Sickle SCAN point-of-care test (BioMedomics Inc., United States). We used SPSS version 23 to analyze the data. On determining the association between level of knowledge and socio-demographic factors, we used Pearson's Chi-square and multivariate logistic regression in ascertaining the strength of associations. Results: Of the 600 participants, the majority were of the age between 26 and 35 years (51%), with the parity of 1-3 children (55.8%) and secondary level of education (43%), while 56% were self-employed. Only 14.7% had good knowledge on SCD. The majority of the participants had ever heard of SCD (81.3%), most of them heard from the streets (42.4%), and only 2.4% heard from hospitals. Of all 600 study participants, only 2 (0.3%) knew their SCD status while 7.7% declared having a family history of SCD. A proficient level of knowledge on SCD is associated with a high level of education, occupation, and knowing personal status of SCD. Among 300 participants who were screened for SCD, 252 were Hb-AA (84%), 47 were Hb-AS (15.7%), and 1 (0.3%) was Hb-SS. Conclusion: Despite the high prevalence of hemoglobin-S among pregnant women attending antenatal clinics in urban settings in Tanzania, there is a poor level of knowledge on SCD and personal knowledge of SCD status. Maternal screening and health education on SCD should be included as part of the comprehensive package for health promotion at antenatal clinics.

High Fecal Carriage of Multidrug Resistant Bacteria in the Community among Children in Northwestern Tanzania

Colonization of multidrug resistant (MDR) bacteria is associated with subsequent invasive infections in children with comorbidities. This study aimed to determine the resistance profile and factors associated with MDR pathogen colonization among HIV−and HIV+ children below five years of age in Mwanza, Tanzania. A total of 399 (HIV− 255 and HIV+ 144) children were enrolled and investigated for the presence of MDR bacteria. The median [IQR] age of children was 19 (10–36) months. Out of 27 Staphylococcus aureus colonizing the nasal cavity, 16 (59.5%) were methicillin resistant while 132/278 (47.2%) of Enterobacteriaceae from rectal swabs were resistant to third generation cephalosporins, with 69.7% (92/132) exhibiting extended spectrum beta lactamase (ESBL) phenotypes. The proportion of resistance to gentamicin, amoxicillin/clavulanic acid and meropenem were significantly higher among HIV+ than HIV− children. A history of antibiotic use in the last month OR 2.62 [1.1, 6.9] (p = 0.04) and history of a relative admitted from the same household in the past three months OR 3.73 [1.1, 13.2] (p = 0.03) independently predicted ESBL rectal colonization. HIV+ children had significantly more fecal carriage of isolates resistant to uncommonly used antibiotics. There is a need to strengthen antimicrobial stewardship and Infection Prevention and Control (IPC) programs to prevent the emergence and spread of MDR pathogens in children.

Healthcare Workers' Knowledge and Resource Availability for Care of Sickle Cell Disease in Dar es Salaam, Tanzania

Background: Sickle cell disease (SCD) is a global public health priority due to its high morbidity and mortality. In Tanzania, SCD accounts for 7% of under-five mortality. Cost-effective interventions such as early diagnosis and linkage to care have been shown to prevent 70% of deaths but require knowledge among healthcare workers and availability of resources at health facilities. In Tanzania, data on these critical determinants are currently lacking. Objective: To assess healthcare workers' knowledge and resource availability for care of SCD at health facilities in Dar es Salaam, Tanzania. Methodology: A facility-based cross-sectional study was conducted between December 2020 and February 2021 among 490 nurses and clinicians at Regional Referral Hospitals (Temeke, Amana, and Mwananyamala) and Muhimbili National Hospital in Dar es Salaam, Tanzania. Data were collected using a pre-tested structured questionnaire consisting of 13 knowledge questions (scored good knowledge if correct response in >7) and an inventory check list to record available resources. Pearson's χ² was used to determine the association between level of knowledge and demographic factors. Multivariate logistic regression was used to ascertain the strength of associations. A two-tailed p-value <0.05 was considered to be statistically significant. Results: Of the 490 participants (median age 28 years [IQR = 26-35]), only 25.1% had good knowledge on SCD. The odds of good knowledge was 82% lower in nurses than clinicians (AOR = 0.177; 95% CI: 0.090, 0.349; p < 0.001); 95% lower in diploma than Master's degree holders (AOR = 0.049; 95% CI: 0.008, 0.300; p = 0.001) and 4.6 times higher in those with 5-9 years than ≥10 years of experience (AOR = 4.564; 95% CI: 1.341, 15.525; p = 0.015). The regional-level hospitals lacked diagnostic tests and hydroxyurea therapy. Conclusion: There was general lack of knowledge on SCD among healthcare workers and limited availability of critical resources for the diagnosis and care of SCD, especially at regional-level hospitals. Efforts are needed for their improvement to enhance care to patients, thus reducing the morbidity and mortality due to SCD in Tanzania.

Advances in training of the specialized human resources for health in Tanzania: the case of Muhimbili University of Health and Allied Sciences

BACKGROUND

Increasing the number of specialized human resources for health is paramount to attainment of the United Nations sustainable development goals. Higher learning institutions in low-and middle-income countries must address this necessity. Here, we describe the 5-years trends in accreditation of the clinical and non-clinical postgraduate (PG) programmes, student admission and graduation at the Muhimbili University of Health and Allied Sciences (MUHAS) in Tanzania, highlighting successes, challenges and opportunities for improvement.

METHODS

This was a retrospective longitudinal study describing trends in PG training at MUHAS between 2015 and 2016 and 2019-2020. Major interventions in the reporting period included university-wide short course training programme to faculty on curricula development and initiation of online application system. Data were collected through a review of secondary data from various university records and was analyzed descriptively. Primary outcomes were the number of accredited PG programmes, number of PG applicants as well as proportions of applicants selected, applicants registered (enrolled) and students graduated, with a focus on gender and internationalization (students who are not from Tanzania).

RESULTS

The number of PG programmes increased from 60 in 2015-2016 to 77 in 2019-2020, including programmes in rare fields such as cardiothoracic surgery, cardiothoracic anesthesia and critical care. The number of PG applications, selected applicants, registered applicants and PG students graduating at the university over the past five academic years had steadily increased by 79, 81, 50 and 79%, respectively. The average proportions of PG students who applied, were selected and registered as well as graduated at the university over the past five years by gender and internationalization has remained stably at 60% vs. 40% (male vs. female) and 90% vs. 10% (Tanzanian vs. international), respectively. In total, the university graduated 1348 specialized healthcare workers in the five years period, including 45 super-specialists in critical fields, through a steady increase from 200 graduates in 2015-2016 to 357 graduates in 2019-2020. Major challenges encountered include inadequate sponsorship, limited number of academic staff and limited physical infrastructure for teaching.

CONCLUSION

Despite challenges encountered, MUHAS has made significant advances over the past five years in training of specialized and super-specialized healthcare workforce by increasing the number of programmes, enrollment and graduates whilst maintaining a narrow gender gap and international relevance. MUHAS will continue to be the pillar in training of the specialized human resources for health and is thus poised to contribute to timely attainment of the health-related United Nations sustainable development goals in Tanzania and beyond, particularly within the Sub-Saharan Africa region.

The role of community advisory boards in community-based HIV clinical trials: a qualitative study from Tanzania

BACKGROUND

Community Advisory Boards (CAB) have become essential organs of involving communities in HIV clinical trials especially in developing countries. However, limited empirical evidence exists on the role of CABs in low and middle-income countries including Tanzania. This study aims at exploring the role of CABs in community-based HIV clinical trials conducted in Tanzania.

METHODOLOGY

We adopted a phenomenological approach to purposefully select HIV clinical trial stakeholders. These included CAB members, researchers and Institutional Review Board (IRB) members in Tanzania. We conducted In-depth Interviews (IDIs) with ten participants and three Focus Group Discussions (FGDs) with eighteen participants. The data were thematically analyzed with the aid of MAXQDA software version 20.2.1.

RESULTS

The findings indicate that at every stage of implementation of a community-based HIV clinical trial, a functioning CAB is important for its success. This importance is based on contextualization of the informed consent process and protocol, managing rumours in the community, weighing trial risks and benefits, sensitizing the community, assisting participant recruitment, tracing and retention. However, being perceived as financial beneficiaries than community representatives emerged as a challenge to CAB members.

CONCLUSION

The study empirically indicates the need for functioning CABs in every stage of implementation of community-based HIV clinical trials. The roles of which are interwoven in serving research goals and protecting the interests of the community and that of trial participants.

A mixed methods needs assessment and gap analysis for establishment of a cancer research training program in East Africa

Background

The burden of non-communicable diseases (NCDs), including cancer, in Africa is rising. Policymakers are charged with formulating evidence-based cancer control plans; however, there is a paucity of data on cancers generated from within Africa. As part of efforts to enhance cancer research training in East Africa, we performed a needs assessment and gap analysis of cancer-related research training resources in Tanzania.

Methods

A mixed-methods study to evaluate existing individual, institutional, and national resources supporting cancer research training in Tanzania was conducted. Qualitative data were collected using in-depth interviews while quantitative data were collected using self-administered questionnaires and online surveys. The study also included a desk-review of policy and guidelines related to NCD research and training. Study participants were selected to represent five groups: (i) policymakers; (ii) established researchers; (iii) research support personnel; (iv) faculty members in degree training programs; and (v) post-graduate trainees.

Results

Our results identified challenges in four thematic areas. First, there is a need for coordination and monitoring of the cancer research agenda at the national level. Second, both faculty and trainees identified the need for incorporation of rigorous training to improve research competencies. Third, sustained mentoring and institutional investment in development of mentorship resources is critical to empowering early career investigators. Finally, academic institutions can enhance research outputs by providing adequate research infrastructure, prioritizing protected time for research, and recognizing research accomplishments by trainees and faculty.

Conclusions

As we look towards establishment of cancer research training programs in East Africa, investment in the development of rigorous research training, mentorship resources, and research infrastructure will be critical to empowering local health professionals to engage in cancer research activities.

Reliability of visual assessment of neonatal jaundice among neonates of black descent: a cross-sectional study from Tanzania

BACKGROUND

Jaundice is common among neonates and if untreated can lead to kernicterus. Diagnosing neonatal jaundice (NJ) using Kramer's method (visual assessment) is considered user-friendly in resource-limited areas. However, there are conflicting findings on reliability of the Kramer's method in the diagnosis of NJ, particularly of black descent. Therefore, study aimed to determine the accuracy of Kramer's method in comparison to the total serum bilirubin (TSB) test in the diagnosis of NJ among neonates of black descent in Tanzania.

METHODS

A cross-sectional study was conducted between June and July 2020 at Muhimbili National Hospital (MNH) in Dar es Salaam Tanzania. A total of 315 neonates were recruited consecutively. In each neonate, jaundice was assessed using Kramer's method and TSB test. NJ A total of 315 neonates were recruited i. A 2 X 2 table was created for the determination of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive and negative likelihood ratios (+LR/-LR), and diagnostic accuracy (effectiveness) of Kramer's method. Cohen kappa (κ) was used to analyze the agreement between Kramer's method and TSB. Association between independent variables and presence of jaundice were assessed using the chi-square test and the p < 0.05 was considered to be statistically significant.

RESULTS

The prevalence of NJ was 49.8% by Kramer's method and 63.5% by TSB. The Sensitivity, Specificity, PPV, and NPV of Kramer's method were 70.5, 86.1, 89.8, and 62.6%, respectively. The +LR and -LR were 5.07 and 0.34, respectively. The diagnostic accuracy of Kramer's method was 76.1%. There was a moderate agreement between Kramer's method and TSB results (κ = 0.524, P<0.001). No significant relationship was observed between the independent variables and the presence of NJ.

CONCLUSION

Kramer has a good positive predictive value. However, due to low sensitivity and NPV one cannot say that overall predictive ability is good. Also, clinical assessment by Kramer's method should not be used for screening of NJ. Further studies are needed to investigate the utility of other non-invasive techniques in detecting NJ among neonates of black descent.

Utilization of Pneumococcal Vaccine and Penicillin Prophylaxis in Sickle Cell Disease in Three African Countries: Assessment among Healthcare Providers in SickleInAfrica

Sickle cell disease is a genetic disease with a predisposition to infections caused by encapsulated organisms, especially Streptococcus pneumoniae. Pneumococcal vaccines and prophylactic penicillin have reduced the rate of this infection and mortality in sickle cell disease. However, implementation of these interventions is limited in Africa. The objectives of the study were to assess health care providers' behaviors with the implementation of pneumococcal vaccination and penicillin prophylaxis and to identify barriers to their use. A 25-item online questionnaire was administered through SickleinAfrica: a network of researchers, and healthcare providers, in Ghana, Nigeria, and Tanzania, working to improve health outcomes of sickle cell disease in Africa. Data was collected and managed using the Research Electronic Data Capture (REDCap), tools and data analysis was done using STATA version 13 and R statistical software. Eighty-two medical practitioners responded to the questionnaire. Only 54.0 and 48.7% of respondents indicated the availability of published guidelines on sickle cell disease management and pneumococcal vaccine use, respectively, at their facilities. The majority (54.0%) perceived that the vaccines are effective but over 20.0% were uncertain of their usefulness. All respondents from Ghana and Tanzania affirmed the availability of guidelines for penicillin prophylaxis in contrast to 44.1% in Nigeria. Eighty-five percent of respondents affirmed the need for penicillin prophylaxis but 15.0% had a contrary opinion for reasons including the rarity of isolation of Streptococcus pneumoniae in African studies, and therefore, the uncertainty of its benefit. Lack of published guidelines on the management of sickle cell disease and doubts about the necessity of prophylactic measures are potential barriers to the implementation of effective interventions.

Prevalence of Multidrug Resistant UTI Among People Living with HIV in Northern Tanzania

Background

Bacterial urinary tract infection (BUTI) is the commonest urinary tract infection among people living with human immunodeficiency virus (PLHIV). It causes significant morbidity in this vulnerable group. Immunosuppression due to HIV can mask the signs and symptoms of infection leading to asymptomatic disease. There is limited evidence in Tanzania regarding BUTI and PLHIV. This study aimed to determine the prevalence, etiology, risk factors and susceptibility pattern of isolates causing asymptomatic UTI in PLHIV at Kilimanjaro Christian Medical Centre (KCMC).

Patients and Methods

This cross-sectional study was conducted from July to September 2020 at Kilimanjaro Christian Medical Centre (KCMC) hospital. A questionnaire was used to collect social demographic data from patients' files together with necessary information required by this study. Urine samples were obtained from participants for urinalysis and urine culture and sensitivity. Data from 300 adults aged ≥18 years were analyzed using Statistical Package for Social Science (SPSS) version 22. Mean or median with their measure of dispersion were calculated for continuous variables. Logistic regression was used to determine associations between variables, where P-value <0.05 was considered to be significant.

Results

Bacteriuria was prevalent in 37 (12.3%) of PLHIV. Positive nitrite in urine was associated with bacteriuria (P = 0.01). Gram-positive bacteria were the most common 25 (67.6%) isolates with high sensitivity to nitrofurantoin (88.2%) followed by gentamycin (69.2%). However, resistance was high against ciprofloxacin (77.8%). Multidrug resistance (MDR) was noted in 17 (45.9%).

Conclusion

One in eight of PLHIV attending CTC at KCMC referral hospital in Northern zone of Tanzania have BUTI. Presence of nitrites in urine is an important biomarker associated with BUTI. About two third of the isolates were Gram-positive bacteria, and nearly half of all isolates showed MDR to commonly used antibiotics.

Building sustainable research capacity at higher learning institutions in Tanzania through mentoring of the Young Research Peers

BACKGROUND

Sustainability of research culture in Sub-Saharan Africa is threatened in part by the lack of a critical mass of young researchers with the requisite skills and interest to undertake research careers. This paper describes an intensive mentorship programme combining hierarchical (vertical) and peer-to-peer (horizontal) mentoring strategies among young researchers in a resource limited setting in Sub-Saharan Africa.

METHODS

A consortium of three partnering large Tanzanian health training institutions (MUHAS, CUHAS and KCMUCo) and two collaborating US institutions (UCSF and Duke University) was formed as part of the five-year Transforming Health Professions Education in Tanzania (THET) project, funded by the NIH through Health Professional Education Partnership Initiative (HEPI). Within THET, the Community of Young Research Peers (CYRP) was formed, comprising of inter-professional and cross-institutional team of 12 Master-level Young Research Peers and 10 co-opted fellows from the former MEPI-Junior Faculty (MEPI-JF) project. The Young Peers received mentorship from senior researchers from the consortium through mentored research awards and research training, and in turn provided reciprocal peer-to-peer mentorship as well as mentorship to undergraduate students.

RESULTS

At the end of the first 2 years of the project, all 12 Young Peers were proceeding well with mentored research awards, and some were at more advanced stages. For example, three articles were already published in peer reviewed journals and two other manuscripts were in final stages of preparation. All 12 Young Peers participated in CYRP-wide thematic training workshops on mentoring and secondary data analysis; 11 had undertaken at least three research training short courses in identified areas of need; 9 joined at least one other ongoing research project; 5 made at least one scientific presentation, and 5 participated in at least one submitted grant application. Half of the Young Peers have enrolled in PhD programmes. A collective total of 41 undergraduate students were actively mentored by the Young Peers in research.

CONCLUSION

The CYRP has demonstrated to be an effective model for dual vertical and horizontal mentorship in research to young investigators in resource-limited settings. This model is recommended to educators working on developing research competence of early career researchers, particularly in Sub-Saharan Africa.

Establishing a Multi-Country Sickle Cell Disease Registry in Africa: Ethical Considerations

Sickle cell disease (SCD) is one of the most prevalent genetic conditions in sub-Saharan Africa. It is a chronic, lifelong disease often characterized by severe pain. However, SCD has received little investment terms of health research, though there is currently a growing pool of SCD data from health and research facilities in different countries. To facilitate research on SCD in Africa, the SickleInAfrica consortium has established a SickleInAfrica registry. The registry will store a systematic collection of longitudinal data from persons with SCD across sub-Saharan Africa, and currently, participants are being enrolled in Ghana, Nigeria, and Tanzania. In establishing this registry, the SickleInAfrica consortium decided to actively identify and anticipate possible ethical issues that may arise in the development and management of the registry. This was motivated, in part, by the near absence of well documented ethical issues for registry research in Africa, more-so for registries enrolling participants across multiple countries and for a genetic condition. The consortium aims to establish standards for the equitable use of data stored in the registry. This paper presents a comprehensive report on the ethical considerations that came up in setting up a genetic disease registry across multiple African countries and how they were addressed by the SickleInAfrica consortium. Major issues included: active involvement of patients in the initiation and management of the registry; questions of assent and re-consent; the importance of ensuring that fears of exploitation are not replicated in African–African research collaborations; and the importance of public engagement in the management of registries. Drawing on this experience, SickleInAfrica plans to set up an ethics helpdesk for genetic disease registries and research in Africa.

Attitudes and Barriers to Research Among Oncology Trainees in East Africa

BACKGROUND

East Africa is one of the fastest growing regions in the world and faces a rising burden of cancer; however, few people are equipped to effectively conduct research in this area.

MATERIALS AND METHODS

A 31-item questionnaire was distributed to current trainees and recent graduates of the Master in Medicine in Clinical Oncology Program at Muhimbili University of Health and Allied Sciences in Tanzania. Areas that were assessed included (a) demographic information, (b) prior research training, (c) prior and current research activities, (d) attitudes toward the importance of research, and (e) supports and barriers to inclusion of research in an oncology career path.

RESULTS

A total of 30 individuals responded to the survey, of whom 53% (n = 16) were male and 70% (n = 21) identified as current trainees. Among the majority of respondents, attitudes toward research were strongly favorable. Although only 37% (n = 11) reported receiving any formal training in research methodology, 87% (n = 26) reported intentions to incorporate research into their careers. The absence of protected time for research and lack of access to research funding opportunities were identified by a majority of respondents as critical barriers.

CONCLUSION

A majority of current or recent oncology trainees in Tanzania desire to incorporate research into their careers, but most also lack adequate training in research methodology and longitudinal mentorship. Our future collaboration will focus on creation of appropriate research training curriculums and fostering an environment that catalyzes interprofessional development and transforms and extends context-specific cancer research in East Africa.

IMPLICATIONS FOR PRACTICE

Current and recent oncology trainees in East Africa expressed a high enthusiasm for research, driven by a sense of urgency related to the burden from cancer that the region faces. This highlights the need for cancer research training and mentorship in this setting. This work hypothesizes that African principal investigators can operate effectively if proper attention is given to selection and provision of high-quality foundational didactic training to learn the theory and implementation of research as well as to the development of an environment conducive to mentoring.

Alteration of lymphocyte phenotype and function in sickle cell anemia: Implications for vaccine responses

Individuals with sickle cell anemia (SCA) have increased susceptibility to infections, secondary to impairment of immune function. Besides the described dysfunction in innate immunity, including impaired opsonization and phagocytosis of bacteria, evidence of dysfunction of T and B lymphocytes in SCA has also been reported. This includes reduction in the proportion of circulating CD4+ and CD8+ T cells, reduction of CD4+ helper: CD8+ suppressor T cell ratio, aberrant activation and dysfunction of regulatory T cells (Treg ), skewing of CD4+ T cells towards Th2 response and loss of IgM-secreting CD27 + IgM(high) IgD(low) memory B cells. These changes occur on the background of immune activation characterized by predominance of memory CD4+ T cell phenotypes, increased Th17 signaling and elevated levels of C-reactive protein and pro-inflammatory cytokines IL-6 and TNF-α, which may affect the immunogenicity and protective efficacy of vaccines available to prevent infections in SCA. Thus, in order to optimize the use of vaccines in SCA, a thorough understanding of T and B lymphocyte functions and vaccine reactivity among individuals with SCA is needed. Studies should be encouraged of different SCA populations, including sub-Saharan Africa where the burden of SCA is highest. This article summarizes our current understanding of lymphocyte biology in SCA, and highlights areas that warrant future research. Am. J. Hematol. 91:938-946, 2016. © 2016 Wiley Periodicals, Inc.

Bacteraemia in sickle cell anaemia is associated with low haemoglobin: a report of 890 admissions to a tertiary hospital in Tanzania

Bacteraemia is a leading cause of morbidity in sickle cell anaemia (SCA), but information from studies in Africa is limited. We evaluated 890 admissions from 648 SCA patients at a tertiary hospital in Tanzania. Bacteraemia was present in 43 admissions (4·8%); isolates included Staphylococcus aureus (12/43; 28%), non‐Typhi Salmonella (9/43; 21%), Streptococcus pneumoniae (3/43; 7%) and Salmonella Typhi (2/43; 5%). Compared to SCA patients without bacteraemia, SCA patients with bacteraemia had significantly lower haemoglobin [71 g/l vs. 62 g/l, odds ratio 0·72 (95% confidence interval 0·56–0·91), P < 0·01]. Further exploration is needed of the relationship between anaemia and bacterial infections in SCA in Africa.

Human seminal plasma fosters CD4(+) regulatory T-cell phenotype and transforming growth factor-β1 expression

PROBLEM

Semen mediates expansion of CD4(+) regulatory T cells (Treg) in the murine female reproductive tract. The impact of semen on Treg in humans, however, remains unclear.

METHOD OF STUDY

Using seminal plasma (SP) from 20 healthy donors, we investigated the impact of human semen on CD4(+) T-cell expression of CD127 and CD49d as well as CD4(+) CD127(low) CD49d(low) Treg proliferation, apoptosis, and intracellular expression of FoxP3, TGF-β1, and IL-10.

RESULTS

SP reduced CD4(+) T-cell expression of CD127 and CD49d and increased the proportion of CD127(low) CD49d(low) Treg. This increase was non-proliferative, mediated in part via the conversion of CD4(+) helper T cells into FoxP3(-) but not FoxP3(+) Treg. Additionally, SP induced an increase in intracellular expression of the immunosuppressive cytokine TGF-β1 by the FoxP3(-) but not FoxP3(+) Treg. SP had no impact on Treg intracellular expression of IL-10.

CONCLUSION

Human seminal plasma fosters the non-proliferative increase in the proportion and immunoregulatory activity of FoxP3(-) Treg.

Semen protects CD4+ target cells from HIV infection but promotes the preferential transmission of R5 tropic HIV

Sexual intercourse is the major means of HIV transmission, yet the impact of semen on HIV infection of CD4(+) T cells remains unclear. To resolve this conundrum, we measured CD4(+) target cell infection with X4 tropic HIV IIIB and HC4 and R5 tropic HIV BaL and SF162 after incubation with centrifuged seminal plasma (SP) from HIV-negative donors and assessed the impact of SP on critical determinants of target cell susceptibility to HIV infection. We found that SP potently protects CD4(+) T cells from infection with X4 and R5 tropic HIV in a dose- and time-dependent manner. SP caused a diminution in CD4(+) T cell surface expression of the HIVR CD4 and enhanced surface expression of the HIV coreceptor CCR5. Consequently, SP protected CD4(+) T cells from infection with R5 tropic HIV less potently than it protected CD4(+) T cells from infection with X4 tropic HIV. SP also reduced CD4(+) T cell activation and proliferation, and the magnitude of SP-mediated suppression of target cell CD4 expression, activation, and proliferation correlated closely with the magnitude of the protection of CD4(+) T cells from infection with HIV. Taken together, these data show that semen protects CD4(+) T cells from HIV infection by restricting critical determinants of CD4(+) target cell susceptibility to HIV infection. Further, semen contributes to the selective transmission of R5 tropic HIV to CD4(+) target cells.
