NCT ID: NCT05028725 Not yet recruiting - Clinical trials for Esophageal Squamous Cell Carcinoma

Novel Strategy for Early Detection of Esophageal Squamous Cell Carcinoma

Start date: October 31, 2021
Phase: N/A
Study type: Interventional

In the current protocol, we propose a study to evaluate a novel, combined esophageal sponge-methylation biomarker strategy for the early detection of esophageal squamous cell carcinoma (ESCC) as well as its precursor, esophageal squamous dysplasia (ESD). This strategy leverages the 'EsophaCap', a swallowable, retrievable sponge, with subsequent evaluation of the sample using a novel molecular biomarker assay. This biomarker assay evaluates methylation levels in three genes, which have been shown to differ significantly between ESCC cases and controls in pilot studies. Detection of methylation markers highly associated with ESCC could help identify patients with concurrent ESCC or at high risk of imminently developing this condition. If successful, this strategy could result in a paradigm shift for esophageal cancer control strategies in Tanzania and other high-incidence ESCC regions

NCT ID: NCT05013346 Recruiting - Type 1 Diabetes Clinical Trials

Characteristics of Young-onset Diabetes in Sub-Saharan Africa (YODA) Study

YODA
Start date: September 1, 2019
Phase:
Study type: Observational

Type 1 diabetes has been poorly characterised, with very sparse information available in the literature about the characteristics of the disease in Africa. Atypical young onset diabetes is often reported by clinicians in sub-Saharan Africa, including patients who have the phenotype of type 1 diabetes but do not appear to have an absolute insulin requirement. The onset of type 1 diabetes in many sub-Saharan African populations seem to occur at later ages (20s to 40s) than what is generally seen in Caucasian populations. The investigators seek to characterise young-onset insulin treated diabetes (clinically diagnosed type 1 diabetes) in sub-Saharan Africa;

NCT ID: NCT04958577 Recruiting - Mental Health Clinical Trials

Clinic Waiting Room-based Study of Swahili Language Artificial Intelligence-driven Symptom Assessments in Tanzanian Primary Health Care Facilities

AFYA
Start date: August 3, 2021
Phase:
Study type: Observational

This study will evaluate the accuracy of the condition suggestions and urgency advice of the Swahili language Ada symptom assessment application (SAA), when symptoms are input by a lay-person user and a medical professional; these SAA results will then be compared to the condition suggestions and urgency advice of different tiers of doctors and a "gold standard" created by a panel.

NCT ID: NCT04948580 Not yet recruiting - Clinical trials for Violence by Teachers

Preventing Violence by Teachers Against Children in Sub-Saharan Africa

EVIDENCE
Start date: September 1, 2021
Phase: N/A
Study type: Interventional

Violence has severe and long-lasting negative consequences for children's and adolescents' well-being and psychosocial functioning, thereby also hampering communities' and societies' economic growth. Studies show high prevalence of violence by teachers against children in Sub-Saharan Africa, both in countries where violence is lawful as disciplinary measure at school and in countries where it has been officially banned. In addition to legal and structural factors (e. g. stressful working conditions for teachers), attitudes favoring violence against children as an effective and acceptable discipline method and the lack of access to alternative non-violent strategies are likely to contribute to teachers' ongoing use of violence against children. Notwithstanding, there are currently very few school-level interventions to reduce violence by teachers that a) have been scientifically evaluated and b) that focus both on changing attitudes towards violence and on equipping teachers with non-violent discipline strategies. Thus, the present study tests the effectiveness of the preventative intervention Interaction Competencies with Children - for Teachers (ICC-T) in primary and secondary schools in Tanzania, Uganda and Ghana. Previous studies have provided initial evidence on the feasibility and effectiveness of ICC-T to reduce teacher violence in primary and secondary schools in Tanzania and secondary schools in Uganda. This study aims to provide further evidence for the effectiveness of ICC-T to reduce violence and to improve children's functioning (i.e. mental health, well-being, academic performance) across educational settings, societies and cultures.

NCT ID: NCT04944966 Enrolling by invitation - Malaria Clinical Trials

Safety and Efficacy of Maytenus Senegalensis for the Treatment of Uncomplicated Malaria

MALHERBAL
Start date: June 2, 2021
Phase: Phase 2
Study type: Interventional

Antimalarial Herbal medicine known as Maytenus senegalensis will be evaluated for its safety, tolerability and efficacy among Tanzanian male adults aged 18 to 45 years. The first primary objective is to assess the safety and tolerability of malaria herbal remedy of Maytenus senegalensis among healthy male adults aged 18 to 45 years in Tanzania. And the second objective is to evaluate the safety, tolerability as well as efficacy of malaria herbal remedy Maytenus senegalensis (MALHERBAL) for the treatment of Tanzanian adults aged 18 to 45 years with uncomplicated malaria compared to Artemether-lumefantrine.

The study evaluates the pharmacokinetics (PK), safety and tolerability of oxfendazole, after administration as a tablet formulation in healthy male and female participants.

NCT ID: NCT04863898 Recruiting - Clinical trials for Drug Use Stigma in HIV Treatment Clinics

Addressing Drug Use Stigma in HIV Care and Treatment Clinics in Tanzania

Start date: February 17, 2021
Phase: N/A
Study type: Interventional

The goal of this study is to adapt and pilot an effective health facility HIV stigma-reduction intervention to address drug use stigma in HIV care and treatment clinics (CTCs) in Tanzania, a barrier to linkage and retention in HIV care for people living with HIV (PLWH) who use drugs. In Tanzania, there are an estimated 300,000 people who use drugs (PWUD), primarily heroin. Although most heroin is inhaled or ingested, an estimated 10% (30,000) of PWUD inject. HIV prevalence among PWUD who do not inject (18-25%) and those who do inject (35%) is 4-7 times higher than in the general population (5%). PWUD face high levels of stigma, including when they try to seek HIV treatment at HIV CTCs, presenting a barrier to linkage and retention in HIV treatment for this highly HIV vulnerable group. Therefore, reducing drug use stigma in HIV CTCs is critical to improving access to and retention in HIV treatment services for PWUD. In response to this need, the investigators will: 1. Adapt a health facility HIV stigma-reduction participatory training intervention to address drug use stigma in HIV CTCs (Aim 1). 2. Pilot test the adapted drug use stigma-reduction intervention for acceptability, appropriateness, and feasibility (Aim 2). The investigators will achieve Aim 1 through a systematic, multi-stage adaptation process that will include a formative phase of in-depth interviews with PLWH who use drugs and CTC staff to inform initial adaptation of the Health Policy Plus (HP+) intervention. Stakeholders, including PLWH who use drugs and CTC staff, will provide feedback on the initial materials through a participatory workshop, leading to a training manual that will be reviewed by topic experts and then finalized. Experienced Tanzanian HIV stigma-reduction trainers, including people with lived experience of drug use, will be trained to deliver the intervention to CTC staff. The pilot test will include 150 health workers based in seven CTCs in Dar-es-Salaam. A mixed methods evaluation will comprise pre-post surveys, observation of trainings, and post-training focus group discussions with intervention participants and trainers. Changes in CTC staff's mean scores on stigma scales from pre- to post-intervention will be assessed, along with measures of intervention acceptability, appropriateness, and feasibility. Focus groups will explore themes around the experience of participating in the drug use stigma-reduction training.
