Summary: In Tanzania, the prevalence of active pulmonary tuberculosis (TB) in patients with diabetes mellitus (DM) was 1.8%, with 54.5% diagnosed through GeneXpert testing and 45.5% diagnosed based on clinical symptoms and chest radiographs. The risk of active TB was lower in patients aged 45-64 years compared to those below 45 years, and in patients with normal chest examination findings compared to those with abnormal findings.

Summary: Tuberculosis (TB) is a significant global health concern, especially in Sub Saharan Africa (SSA) where it accounts for 25% of the global burden. A study conducted in Mererani, northern Tanzania, found a high prevalence of TB (7%) among mining communities, much higher than the national average. Risk factors for TB included lower education level, previous lung disease, and symptoms of TB.

Summary: We conducted a mass tuberculosis screening program for nearly 90,000 individuals with diabetes. The program was feasible but had a low yield of disease detection and was not cost-efficient. This study evaluated the yield and costs of mass screening among individuals with type 2 diabetes in eastern China.

Summary: The aim of this study was to examine the risk factors of cognitive dysfunction in patients with diabetes and compare cognitive screening results in different clinical settings. The study found that older adults with diabetes in the geriatric and geriatric-endocrine settings were more likely to have lower Mini-Cog scores and higher prevalence of hypertension and cardiovascular events. Age > 75 years, previous cardiovascular events, and body mass index < 30 were significantly associated with lower Mini-Cog scores.

Summary: The study aimed to explore the feasibility of using a portable UV spectrophotometer to measure levofloxacin concentrations in saliva of MDR-TB patients. Results showed a positive linear correlation between serum and saliva AUC(0-24), with the spectrophotometry method demonstrating high sensitivity in detecting subtarget serum AUC(0-24) values below 80mg.h/L. The findings suggest potential for utilizing this method for point-of-care screening and personalized dosing strategies in the future.

Summary: This study assessed the sensitivity and specificity of symptom questioning and chest radiography (CXR) as screening tools for detecting pulmonary tuberculosis disease. The results showed that symptom questioning had low sensitivity but high specificity, while CXR had high sensitivity but low specificity. These findings are important for designing screening and diagnostic algorithms and implementing tuberculosis screening programs in specific settings.

Summary: In this study, the researchers examined the cardiovascular comorbidities among people with HIV in Tanzania. The results showed a high prevalence of hypertension, diabetes, and obesity among the participants, with a majority of them having uncontrolled hypertension. Older age and higher body mass index were associated with uncontrolled hypertension.

Summary: A retrospective study in Tanzania showed that factors such as female sex, obesity, WHO clinical stage II, hospital enrollment, region, and enrollment in public health facilities were associated with increased IPT uptake, while being on ART and severe nutritional status were associated with decreased IPT initiation. Strategies are needed to address barriers and sustain enabling factors to improve IPT coverage.

Summary: The study found that the levels of nonadherence to diabetes management measures are similar among US stroke survivors and those who had never had a stroke, but stroke survivors have lower nonadherence with daily blood glucose checks. Additional interventions are needed to improve diabetes care for stroke survivors in order to reduce the risk of further complications.

Summary: This study aimed to explore the utility of clinical factors in predicting tuberculosis (TB) among people with HIV not seeking care. The study found that CD4 count and antiretroviral initiation were associated with Mycobacterium tuberculosis (Mtb) sensitisation and TB disease. Models incorporating clinical features alone performed poorly in diagnosing prevalent TB and predicting progression to incident TB.

Summary: This review aimed to describe the impact of pertussis on adolescents, adults, and older adults in selected Latin American countries between 2007 and 2018. Limited epidemiological data were available for individuals aged over 10 years, and inconsistencies were found in case definitions, diagnostic methods, and age groups across studies.

Summary: SPHERE is a clinical trial for sickle cell anemia in Tanzania, which incorporates TCD screening to predict stroke risk and provide relevant treatment. The study findings show a high prevalence of elevated baseline TCD velocities and splenomegaly among participants, and SPHERE aims to determine the benefits of hydroxyurea in stroke prevention and expand access to hydroxyurea treatment in Tanzania.

Summary: The REACH study provides hydroxyurea at maximum tolerated dose for children with sickle cell anemia in sub-Saharan Africa, and it not only reduces SCA-related clinical events but also decreases malaria incidence by around 50%. The study analyzed the associations between hydroxyurea and lower malaria rates, through recording infections in clinical sites across Angola, Democratic Republic of Congo, Kenya, and Uganda. The results showed that ANC and splenomegaly were significant factors associated with malaria risk, and hydroxyurea treatment at MTD led to lower malaria incidence through incompletely defined mechanisms.

Summary: This study aimed to estimate stroke risk in children with sickle cell anaemia in Tanzania and determine the efficacy of hydroxyurea to decrease and prevent stroke. The results showed that hydroxyurea at the maximum tolerated dose significantly lowered transcranial Doppler velocities and reduced the risk of stroke, supporting wider access to hydroxyurea for patients with sickle cell anaemia in sub-Saharan Africa.
