Factors associated with adherence to oral HIV pre-exposure prophylaxis among female sex workers in the Mara Region, Tanzania: A 2022 cross-sectional study.

Female sex workers (FSWs) have a higher risk of acquiring human immunodeficiency virus (HIV) infection compared with the general female population. Tanzania adopted pre-exposure prophylaxis (PrEP) use for HIV-negative key populations in 2019 as a strategy to reduce HIV transmission. We aimed to identify factors associated with PrEP adherence among FSWs in Tanzania.

Practice and Knowledge on Type 2 Diabetes Mellitus Risk Factors Among Office Workers in Mwanza City, Tanzania.

Background: Type 2 diabetes mellitus (T2DM) mostly occurs in adults when the body becomes resistant to insulin. Genetic predisposition, age, an unhealthy diet, and a sedentary lifestyle are key factors leading to T2DM. Office workers are one of the populations at greatest risk of developing T2DM.

The Influence of Cytochrome P450 Polymorphisms on Pharmacokinetic Profiles and Treatment Outcomes Among Malaria Patients in Sub-Saharan Africa: A Systematic Review.

Background: Sub-Saharan Africa (SSA) population is genetically diverse and heterogenous thus variability in drug response among individuals is predicted to be high. Cytochrome P450 (CYP450) polymorphisms is a major source of variability in drug response. This systematic review presents the influence of CYP450 single nucleotide polymorphisms (SNPs), particularly CYP3A4*1B, CYP2B6*6 and CYP3A5*3 on antimalarial drug plasma concentrations, efficacy and safety in SSA populations.

Merozoite Surface Proteins Polymorphisms and Treatment Outcomes among Patients with Uncomplicated Malaria in Mwanza, Tanzania.

Background: The severity of malaria infection depends on the host, parasite and environmental factors. Merozoite surface protein (msp) diversity determines transmission dynamics, immunity evasion, and pathogenesis or virulence. There is limited updated information on msp polymorphisms and their impact on artemether-lumefantrine treatment outcomes in Tanzania.

Prevalence of HIV and associated risk factors among street-connected children in Mwanza city.

While on the street, HIV infection among street-connected children is a challenging issue due to the nature of transmission, distribution, and prevention. Lack of proper care and protection, insufficient knowledge of the danger of acquiring HIV, and insufficient or absence of health facilities serving street-connected children have left this vulnerable group engaging in high-risk behaviors exposing them to acquiring HIV. This cross-sectional study aimed at estimating the prevalence of HIV infection and its associated risk factors among street-connected children aged between 10 to17 years in Mwanza City.

The Coverage and Acceptance Spectrum of COVID-19 Vaccines among Healthcare Professionals in Western Tanzania: What Can We Learn from This Pandemic?

The vaccination rate against COVID-19 remains low in developing countries due to vaccine hesitancy. Vaccine hesitancy is a public health threat in curbing COVID-19 pandemic globally. Healthcare professionals have been found to play a critical role in vaccine advocacy and promotion campaigns in the general population.

Therapeutic efficacy of artemether-lumefantrine, artesunate-amodiaquine and dihydroartemisinin-piperaquine in the treatment of uncomplicated Plasmodium falciparum malaria in Sub-Saharan Africa: A systematic review and meta-analysis.

Background: Sub-Saharan Africa has the highest burden of malaria in the world. Artemisinin-based combination therapies (ACTs) have been the cornerstone in the efforts to reduce the global burden of malaria. In the effort to facilitate early detection of resistance for artemisinin derivatives and partner drugs, WHO recommends monitoring of ACT's efficacy in the malaria endemic countries.

Artemether-lumefantrine and dihydroartemisinin-piperaquine treatment outcomes among children infected with uncomplicated Plasmodium falciparum malaria in Mwanza, Tanzania.

Background: Artemisinin based combination therapies (ACTs) have been a cornerstone in the treatment of malaria in the world. A rapid decline in dihydroartemisinin piperaquine (DHP) and artemether lumefantrine (ALU) efficacies has been reported in some parts of South East Asia, the historical epicenter for the antimalarial drug resistance. Prolonged drug use is associated with selection of resistant parasites due to exposure to inadequate drug levels hence effects on treatment outcomes in malaria.

Disposal practices of expired and unused medications among households in Mwanza, Tanzania.

Background: The community practice towards disposal of expired and unused medications in spite of its adverse impact have been widely neglected in many developing countries. The available guidelines in Tanzania focus on the disposal of expired medications and cosmetics in hospitals and community pharmacies only.

Aim: The aim of this study was to assess the disposal practice of expired and unused medications at household level in Mwanza city, north-western Tanzania.

Malaria Morbidities Following Universal Coverage Campaign for Long-Lasting Insecticidal Nets: A Case Study in Ukerewe District, Northwestern Tanzania.

Background: Surveillance of the clinical morbidity of malaria remains key for disease monitoring for subsequent development of appropriate interventions. This case study presents the current status of malaria morbidities following a second round of mass distribution of long-lasting insecticidal nets (LLINs) on Ukerewe Island, northwestern Tanzania.

Methods: A retrospective review of health-facility registers to determine causes of inpatient morbidities for every admitted child aged <5 years was conducted to ascertain the contribution of malaria before and after distribution of LLINs.

Low adherence to Option B+ antiretroviral therapy among pregnant women and lactating mothers in eastern Tanzania.

Background: Adherence to option B+ antiretroviral treatment (ART) is vital to a successful implementation of Prevention of Mother to Child Transmission (PMTCT) program. Further studies show that optimal viral suppression is also crucial for a successful PMTCT program, however barriers to adherence exist and differ among populations and particularly within few years of its adoption in Tanzania. This study therefore aimed at investigating the level and predictors of adherence to ART option B+ among pregnant and lactating women in rural and urban settings of eastern Tanzania.

Prevalence of HIV infection and uptake of HIV/AIDS services among fisherfolk in landing Islands of Lake Victoria, north western Tanzania.

Background: New HIV infections in Tanzania have been decreasing, however some populations remain at higher risk. Despite of that, evidence on the magnitude of HIV infection and the associated factors and HIV/AIDS services uptake among fisherfolk in Tanzania are inadequately explored. This study therefore aimed at determining prevalence of HIV infection and utilization of HIV/AIDS services among fishfolk in selected Islands of Lake Victoria for evidence-based interventions.

The current malaria morbidity and mortality in different transmission settings in Western Kenya.

Background: Passive surveillance of malaria in health facilities remains vital for implementation of control and elimination programs. It is therefore essential understanding current age profile of clinical malaria morbidity, mortality and presentations in areas with variant infection susceptibility. This study aimed at understanding the current malaria morbidity and mortality in Western Kenya.

Utility of passive malaria surveillance in hospitals as a surrogate to community infection transmission dynamics in western Kenya.

Background: Malaria continued to be the major public health concern in sub-Sahara Africa, thus for better planning of control activities, periodic surveillance of both clinical and asymptomatic cases remains important. However, the usability of routinely collected malaria data in Kenyan hospitals as a predictor of the asymptomatic malaria infection in the community amidst rapid infection resurgence or reduction in different areas of disease endemicities remains widely unstudied. This study was therefore aimed to evaluate the utility of passive surveillance of malaria in health facilities as a proxy of infection transmission of the surrounding community in different transmission intensities.

Why some sites are responding better to anti-malarial interventions? A case study from western Kenya.

Background: In sub-Saharan Africa, malaria interventions over the last decades have been successful in reducing both mortality and morbidity. In western Kenya however some areas experience contrasting outcomes of the ongoing interventions while the causes for this observation remains not yet clearly known.

Methods: The WHO insecticide (deltamethrin) susceptibility test of the common malaria vectors was studied.
