Background: Over the years, the processing of research proposals for ethical approvals have been done manually through a review of hard copies. Longer turn-around-time, increased financial costs to researchers and cumbersome submission processes are few of the challenges inherent to paper-based review of research proposals. This has necessitated the shift to electronic management of research proposals, Research Ethics Information Management Systems (REIMS).

Background: Adherence to HIV treatment regimens involves the consistent and correct intake of all prescribed medications. The implementation of antiretroviral therapy (ART) program has significantly reduced mortality among adolescents living with HIV. However, adherence to ART is lower among adolescents compared to other sub-populations and even lower in sub-Saharan Africa.

Article Synopsis
  • Cardiovascular disease (CVD) is a leading cause of premature death among people living with HIV (PLWH), especially in resource-limited settings like Sub-Saharan Africa.
  • A study analyzed cardiovascular health profiles of 995 participants (492 PLWH and 503 HIV-uninfected) in Mwanza, Tanzania, using modified definitions and Poisson regressions.
  • While PLWH showed better metrics in body mass index, blood pressure, and cholesterol, they had higher smoking rates and lower physical activity, indicating that CVD prevention efforts should prioritize smoking cessation and increasing physical activity levels.

Introduction: Malaria remains a significant burden, and a fully protective vaccine against is critical for reducing morbidity and mortality. Antibody responses against the blood-stage antigen Merozoite Surface Protein 2 (MSP2) are associated with protection from malaria, but its extensive polymorphism is a barrier to its development as a vaccine candidate. New tools, such as long-read sequencing and accurate protein structure modelling allow us to study the genetic diversity and immune responses towards antigens from clinical isolates with unprecedented detail.

Background: Prostate cancer is a common cancer among men globally and its treatment affects quality of life. Poor patients' perception of prostate cancer services may lead to their late presentation for care, often presenting with the advanced stage of the disease. This may vary from one region to another.

Objective: Few studies characterizing clinical outcomes of head and neck cancer (HNC) patients in sub-Saharan Africa report the proportion of patients who initiate and complete treatment, information integral to contextualizing survival outcomes. This retrospective cohort study describes HNC patients who presented to Muhimbili National Hospital and Ocean Road Cancer Institute in 2018, the highest-volume oncology tertiary referral centers in Tanzania. Logistic regression was applied to assess predictors of treatment initiation and completion.

Since its inception in 2003, the African Society of Human Genetics (AfSHG) has been central to the promotion of genetics research on the continent, and facilitated the networking of African researchers within Africa and abroad, thereby significantly contributing to the career development of African geneticists. The continuation of these accomplishments was stimulated by the 12 international conference of AfSHG held jointly with the 1 Congress of the Malian Society of Human Genetics (MSHG) in Bamako, Mali from September 18 to 21 2019. The main theme of the conference was "Human Genetics and Genomics as a Unifying Factor for Harmony and Progress in Africa".

Background: Tanzania, like most low- and middle-income countries, is facing an increasing prevalence of obesity in the general population, including among women of reproductive age. Excess weight pre-pregnancy is a risk factor for the onset of gestational diabetes mellitus (GDM), which is associated with several poor pregnancy outcomes. Screening for GDM, as a primary preventive measure, is not systematically done in Tanzania.

Long-term effects of adding biochar to soils on organic matter content, persistent carbon storage, and moisture content in Karagwe, Tanzania.

Sci Rep

December 2024

Department of Thematic Studies: Environmental Change, Centre for Climate Science and Policy Research (CSPR), Linköping University, SE-58183, Linköping, Sweden.

Soils require the application of biochar to improve degradation. The objective of this study was to evaluate the long-term effects of a field experiment on soil organic matter (SOM), soil organic carbon (SOC), and soil moisture content in Karagwe, Tanzania. Seven years ago, a field experiment was conducted using a Latin rectangle design with four replications.

Background: Undernutrition in children is predominantly linked to lack of a balanced diet resulting from inadequate nutrition intake. This form of malnutrition remains a leading cause of morbidity and mortality under-five children, especially prevalent in low-income countries. Understanding the specific factors contributing to undernutrition among this group, particularly those associated with caregivers, is vital yet insufficiently explored.

Background: Feeding practices during infancy have a significant impact on a child's cognitive development and long-term health outcomes. Dietary diversity guidelines from the WHO and UNICEF recommend a diverse range of foods for children aged below 24 months for their optimal growth and development. However, in sub-Saharan Africa (SSA), little is known about the extent to which dietary diversity behaviour in children aged 6 to 24 months aligns with the recommendations and the factors associated with the differentials in dietary behaviour.

Survivin belongs to the inhibitor of apoptosis protein (IAP) family and is encoded by the baculoviral inhibitor of apoptosis repeat-containing, or BIRC5, gene. It is preferentially expressed in cancers with functional complexity in cell signaling cascades such as extracellular signal-regulated kinases (ERK), mitogen-activated protein kinases (MAPK), heat shock protein-90 (HSP90), epidermal growth factor receptor (EGFR), phosphoinositide 3-kinase (PI3K), signal transducer and activator of transcription (STAT), hypoxia-inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor (VEGF), and others. Survivin plays a role in cell division and cell death, properties that have attracted a large body of research to decipher its therapeutic and prognostic significance in cancer.

Background: The rise of hypertension (HTN) and diabetes mellitus (DM) in Tanzania underscores the importance of self-care practices (SCP) for disease management. Despite the proven effectiveness of SCP, financial barriers in resource-limited rural areas hinder continuous care. Health insurance (HI) emerges as a critical solution to alleviate financial constraints and support SCP.
