Non-communicable Diseases Week: Best Practices in Addressing the NCDs Burden from Tanzania.

Background: Five million people die every year from non-communicable diseases (NCDs) globally. In Tanzania, more than two-thirds of deaths are NCD-related. The country is investing in preventive and advocacy activities as well as interventions to reduce the burden. Of particular interest, the Ministry of Health (MoH) commemorates NCDs' week using a multisectoral and multi-stakeholders' approach. This paper highlights activities conducted during NCDs week with the aim of sharing lessons for other countries with similar context and burdens. Methods: A thorough review of official reports and the national strategic plans for NCDs was done including the 2020 and 2021 National NCDs' week reports, the National Strategic Plan for NCDs 2015-2020, and the National NCDs agenda. Findings: NCDs week is commemorated annually throughout the country involving the five key activities. First, community awareness and participation are encouraged through media engagement and community-based preventive and advocacy activities. Second, physical activities and sports festivals are implemented with a focus on developing and renovating infrastructures for sports and recreation. Third, health education is provided in schools to promote healthy behaviors for secondary school adolescents in transition to adulthood. Fourth, health service provision and exhibitions are conducted involving screening for hypertension, diabetes, obesity, alcohol use, and physical activities. The targeted screening of NCDs identified 10% of individuals with at least one NCD in 2020. In 2021, a third of all screened individuals were newly diagnosed with hypertension, and 3% were found to have raised blood glucose levels. Fifth, the national NCDs scientific conferences conducted within the NCDs week provide an avenue for stakeholders to discuss scientific evidence related to NCDs and recommend strategies to mitigate NCDs burden. Conclusion: The initiation of NCDs week has been a cornerstone in advocating for NCDs control and prevention in the country. It has created awareness on NCDs, encourage healthy lifestyles and regular screening for NCDs. The multi-stakeholder and multi-sectoral approaches have made the implementation of the mentioned activities feasible and impactful. This has set an example for the united efforts toward NCD control and prevention at national, regional, and global platforms while considering contextual factors during adoption and implementation.

Improved Biorepository to Support Sickle Cell Disease Genomics and Clinical Research: A Practical Approach to Link Patient Data and Biospecimens from Muhimbili Sickle Cell Program, Tanzania.

In Africa, sickle cell disease phenotypes' genetic contributors remain understudied due to the dearth of databases that pair biospecimens with demographic and clinical details. The absence of biorepositories in these settings can exacerbate this issue. This article documents the physical verification process of biospecimens in the biorepository, connecting them to patient clinical and demographic data and aiding in the planning of future genomic and clinical research studies' experience from the Muhimbili Sickle Cell Program in Dar es Salaam, Tanzania. The biospecimen database was updated with the current biospecimen position following the physical verification and then mapping this information to its demographic and clinical data using demographic identifiers. The biorepository stored 74,079 biospecimens in three -80°C freezers, including 63,345 from 5159 patients enrolled in the cohort between 2004 and 2016. Patients were identified by a control (first visit), entry (when confirmed sickle cell homozygous), admission (when hospitalized), and follow-up numbers (subsequent visits). Of 63,345 biospecimens, follow-ups were 46,915 (74.06%), control 8067 (12.74%), admission 5517 (8.71%), and entry 2846 (4.49%). Of these registered patients, females were 2521 (48.87%) and males were 2638 (51.13%). The age distribution was 1-59 years, with those older than 18 years being 577 (11.18%) and children 4582 (88.82%) of registered patients. The notable findings during the process include a lack of automated biospecimen checks, laboratory information management system, and tubes with volume calibration; this caused the verification process to be tedious and manual. Biospecimens not linked to clinical and demographic data, date format inconsistencies, and lack of regular updating of a database on exhausted biospecimens and updates when biospecimens are moved between positions within freezers were other findings that were found. A well-organized biorepository plays a crucial role in answering future research questions. Enforcing standard operating procedures and quality control will ensure that laboratory users adhere to the best biospecimen management procedures.

Promoting access of hydroxyurea to sickle cell disease individuals: Time to make it an essential medicine.

Hydroxyurea (HU) alone has the potential to prevent one out of every three deaths due to sickle cell disease (SCD) and almost all forms of disabilities caused by SCD. However, in Tanzania, only one out of every six registered SCD patients in the SPARCO-Tanzania Sickle Cell Cohort use HU. We conducted studies to understand factors influencing utilization of HU in Tanzania and discovered that among the reason for low utilization of HU include HU is classified as anticancer medication, only hematologists are supposed to prescribe HU, limited HU prescription to only National and Specialized hospitals, a special permit is required to access HU using National Health Insurance Fund (NHIF) scheme and limited importation and absence of local manufacturing of HU limit availability of this important drug in Tanzania. Therefore, with this brief, the government should allow prescription of HU to the district hospitals level, should allow all clinicians with a minimum of a Bachelor of Medicine to prescribe HU, and accessibility of HU through NHIF should be friendly.
