During the first wave, Tanzania took several measures to prevent wider virus transmission with school closures being one of them. All areas and institutions were targeted, including the refugee camps in Kigoma region.

Conceptualisation of violence and discipline among students, teachers, and parents in Nyarugusu Refugee Camp, Tanzania.

Background: Little academic research has been conducted on how people conceptualise 'violence' and 'discipline', especially in humanitarian settings. This may limit the transferability of violence prevention interventions. This paper examines the understanding of violence and discipline concepts among students, teachers, and parents in the Nyarugusu Refugee Camp in Tanzania.

Humoral Immune Responses following COVID-19 Vaccinations among Adults in Tanzania.

COVID-19 vaccination remains to be the most important intervention in the fight against the pandemic. The immunity among the vaccinated population and its durability can significantly vary due to various factors. This study investigated the humoral immune responses among individuals who received any of the COVID-19 vaccines approved for use in Tanzania.

Two Randomized Trials of Low-Dose Calcium Supplementation in Pregnancy.

Background: The World Health Organization recommends 1500 to 2000 mg of calcium daily as supplementation, divided into three doses, for pregnant persons in populations with low dietary calcium intake in order to reduce the risk of preeclampsia. The complexity of the dosing scheme, however, has led to implementation barriers.

Methods: We conducted two independent randomized trials of calcium supplementation, in India and Tanzania, to assess the noninferiority of a 500-mg daily dose to a 1500-mg daily dose of calcium supplementation.

Management of chronic conditions in resource limited settings: multi stakeholders' perception and experiences with receiving and providing integrated HIV, diabetes and hypertension services in Tanzania.

Background: The rising prevalence of non-communicable diseases (NCDs) alongside the continuing high burden of HIV poses a serious challenge to middle- and low-income countries' healthcare systems. Pilot studies of integrated models of service delivery for HIV, hypertension and diabetes have demonstrated that they are feasible and acceptable among patients and care providers. This study assessed multi-stakeholders' perspectives of the delivery and receipt of integrated care in Tanzania.

Impact of differentiated service delivery models on retention in HIV care and viral suppression among people living with HIV in sub-Saharan Africa: A systematic review and meta-analysis of randomised controlled trials.

Differentiated service delivery (DSD) models, such as adherence clubs (ACs), are client-centred approaches where clinically stable people living with HIV (PLHIV) meet to receive various services, including psychosocial support, brief symptoms screening, and refills of antiretroviral medications, among others. We conducted a review to assess the impact of DSD models, including ACs, on sustaining retention in care (RC) and achieving viral suppression (VS) among PLHIV in sub-Saharan Africa. The review protocol was registered in PROSPERO (CRD42023418988).

The impacts of COVID-19 and its policy response on access and utilization of maternal and child health services in Tanzania: A mixed methods study.

The SARS-Cov-2 virus (COVID-19) has had a global social and economic impact. Despite the growing evidence, its effects on access and delivery of maternal and child health services in low-income countries are still unclear. This cross-sectional case study was conducted in Mjini Magharibi, Chake Chake, and Ilala districts in Tanzania to help fill this gap.

CPAP failure in the management of preterm neonates with respiratory distress syndrome where surfactant is scarce. A prospective observational study.

Background: The mainstay in the management of preterm neonates with respiratory distress syndrome (RDS) include early Continuous Positive Airway Pressure (CPAP), timely surfactant replacement and mechanical ventilation. Preterm neonates with RDS who fail CPAP are at higher risk for chronic lung disease as well as death. Unfortunately, in low resource settings CPAP may be the only treatment available for these neonates.

Molecular and clinicopathologic characterization of pediatric histiocytoses.

The spectrum of somatic mutations in pediatric histiocytoses and their clinical implications are not fully characterized, especially for non-Langerhans cell histiocytosis (-LCH) subtypes. A cohort of 415 children with histiocytosis from the French histiocytosis registry was reviewed and analyzed for BRAF . Most BRAF samples were analyzed by next-generation sequencing (NGS) with a custom panel of genes for histiocytosis and myeloid neoplasia.

Facility-based care for moderately low birthweight infants in India, Malawi, and Tanzania.

Globally, increasing rates of facility-based childbirth enable early intervention for small vulnerable newborns.

Evidence for an enhanced HIV/AIDS policy and care in Cameroon: proceedings of the second Cameroon HIV Research Forum (CAM-HERO) 2021.

To attain the HIV 95-95-95 goals by 2030 in Cameroon, high quality research to inform policy and patient care is of utmost importance. In the context of limited workforce and resources, collaborations, sharing of locally-adapted strategies and other field experience, leveraging on existing and innovative platforms would facilitate a coordinated and optimal AIDS response at country level. The second edition of the Cameroon HIV Research Forum (CAM-HERO) conference took place both physically and virtually on November 18 and 19, 2021 in Kribi, on the theme "Research for Policy and Care".

School readiness among children born to women living with HIV in Dar es Salaam, Tanzania: a cohort study protocol.

Introduction: Children who are born to women living with HIV are at a greater risk of suboptimal neurodevelopment; however, evidence from sub-Saharan Africa is limited and functional developmental outcomes are rarely assessed in this vulnerable population. The School Readiness among HIV-Exposed Children (SRHEC) cohort study aims to assess the school readiness of preschool aged children born to women living with HIV and to identify the biological, environmental and social factors that contribute to school readiness in this population.

Methods And Analysis: The SRHEC cohort is an observational follow-up study of children born to HIV-infected pregnant women who were previously enrolled in a maternal vitamin D supplementation randomised, placebo-controlled trial in Dar es Salaam, Tanzania.

Personal experiences following acquiring HIV infection while volunteering in Phase I/II HIV vaccine trials: A qualitative study from Tanzania.
