Prevalence of lower extremity Peripheral artery disease among adult diabetes patients in Southwestern Uganda

Background: Peripheral artery disease (PAD) is a major complication of atherosclerosis. PAD can be diagnosed with low-cost diagnostic techniques and is associated with significant morbidity and mortality. While the major epidemiologic risk factors for PAD have been established in the western world, data from resource-poor countries are limited. We performed a cross-sectional study to determine the prevalence and correlates of PAD among patients with diabetes at Mbarara Referral Hospital in southwestern Uganda. Methods: We consecutively enrolled diabetes patients aged 50 years or greater presenting to the outpatient clinic. We collected blood for fasting lipid profile, HIV serology, and glycosylated hemoglobin, measured blood pressure and ankle brachial index, and administered the Edinburgh Claudication Questionnaire (ECQ). We also surveyed patients for other PAD risk factors. We used logistic regression to determine correlates of PAD. Results: We enrolled 229 diabetes patients. The median age of 60 years (IQR 55–66), and 146 (63.7%) were female. Fifty five patients (24%) had PAD (ABI of ≤ 0.9). Of these, 48 /55 (87.27%) had mild PAD (ABI 0.71-0.9) while 7/55 (12.73%) had moderate to severe PAD (ABI < 0.7). Amongst those with PAD, 24/55 (43.64%) reported claudication by the ECQ. Correlates of PAD included female sex (AOR 2.25, 95% CI 1.06 - 4.77, p = 0.034), current high blood pressure (AOR 2.59, 95% CI 1.25-5.33, p = 0.01), and being on a sulfonylurea–glibenclamide (AOR 3.47, 95% CI 1.55 - 7.76, p = 0.002). Conclusion: PAD was common in diabetic patients in southwestern Uganda. Given its low cost and ease of measurement, ABI deserves further assessment as a screening tool for both PAD and long term cardiovascular risk amongst diabetics in this region

Pediatric HIV care and treatment services in Tanzania: implications for survival.

BACKGROUND: Improving child survival for HIV-infected children remains an important health agenda. We present progress regarding care and treatment services to HIV infected children in Tanzania. METHODS: The National AIDS Control Programme Care and Treatment (CTC 2) database was used to obtain information of all children aged 0-14yearsenrolled in the HIV Care and Treatment Program between January 2011 and December 2014. We assessed eligibility for ART, time from enrolment to ART initiation, nutritional status, and mortality using Kaplan-Meier methods. RESULTS: A total of 29,531 (14,304 boys and 15,227 girls) ART-naive children aged 0-14 years were enrolled during the period, approximately 6700 to 8000 children per year. The male to female ratio was 48:50. At enrolment 72% were eligible for ART, 2-3% of children were positive for TB, and 2-4% were severely malnourished. Between 2011 and 2014, 2368 (8%) died, 9243 (31%) were Lost to Follow-up and 17,920 (61%) were on care or ART. The probability of death was 31% (95% CI 26-35), 43% (40-47), 52% (49-55) and 61% (58-64) by 1,2, 5 and 10 years of age, respectively. The hazard of death was greatest at very young ages (<2 years old), and decreased sharply by 4 years old. Children who were on ART had around 10-15% higher survival over time. CONCLUSIONS: Significant progress has been made regarding provision of paediatric HIV care and treatment in Tanzania. On average 7000 children are enrolled annually, and that approximately two thirds of children diagnosed under the age of 2 years were initiated on ART within a month. Provision of ART as soon as the child is diagnosed is the biggest factor in improving survival. However we noted that i) most children had advanced disease at the time of enrolment ii) approximately two-thirds of children were missing a baseline CD4 measurement and only 35% of children had either a CD4 count or percentage recorded, indicating limited access to CD4 testing services, and iii) 31% were lost to follow-up (LTFU). These challenges need to be addressed to improve early detection, enrolment and retention of HIV-infected children into care and improve documentation of services offered

Community-based HIV services during Differentiated Service Delivery Models: a cross-sectional survey from nine regions in Tanzania

Introduction: To combat the HIV epidemic and reach the 90-90-90 goals, community-based HIV/AIDS services (CHBS) plays a great role. However, how well CHBS works in the era of adopting differentiated service delivery models for care and treatment has not been adequately evaluated. We hence assessed CBHS programs implemented by various partners with a focus on the coverage; program needs; linkage and referral process; consistent use of guidelines and training curricula and challenges faced by providers and clients. Methods: It was a cross-sectional study conducted in July 2020 in 9 regions using both quantitative and qualitative methods. Quantitative data were analyzed using STATA version 12 and qualitative data were managed using Thematic Content Analysis. Results: 26 implementing partners were offering CBHS in biomedical, behavioral, and structural areas. Their focus was on PLHIV, orphans, and key and vulnerable populations. The majority of PLHIV had a positive perception of different CBHS. Key factors in the perceived effectiveness of community HIV services were the consistent use and availability of guidelines and training curricula, standard operating procedures, and readiness of essential commodities and supplies. Out of 1391 PLHIV who were involved, 67.4% and 25.0% were tested at the health facility and communities respectively. About 69.8% were referred after confirming their seropositivity and forms were not given to about 57.5% when referred from health facilities to communities for CBHS. There was a deficit of 45% in health workers across different cadres, a deficit in all categories of supplies and equipment example the HIV test kit by 53.8%. Challenges for CBHS included financial hindrances, HIV-related stigma, and discrimination, distance to health facilities, and poor incentives for community health workers. Conclusion: it is important to address HIV-related stigma hence accelerating efforts to limit the spread of the HIV epidemic in the respective communities

Reasons Influencing PrEP continuity among Key and Priority Populations in Tabora region, Tanzania. A cross-sectional study.

Background: In Tabora, PrEP continuity 6 months after among newly enrolled among Key and Priority Population (KPP) is low at 47%. However, information on reasons influencing to PrEP continuity in KPP in Tabora is limited. We report study findings from nine (9) health facilities (HFs) in the Tabora region. Methodology:  This was a cross-sectional survey, deployed both quantitative and qualitative methods. 425 current or previous PrEP beneficiaries started PrEP between July 2020 to January 2021 were administered with a structured questionnaire, whereby 157 participants were purposively selected for 18 focused group discussions (FGDs). Recruitment of study participants carried between February to April 2022. Results: A total of 425 KPPs, aged 15-70 years with average 30 years, the majority 288(58%) were FSWs, the proportion of interruption was 25(20.5%). Reported reasons for PrEP interruptions, (57%) were due to drug side effects and the least was migration (3%). There was an association between interruptions and clients’ age (P&lt;0.05), area of service offered (P=0.010.) and being knowledgeable about PrEP: (P&lt;0.05). There is significant relationship between awareness and PrEP interruptions, though in proportions of those aware and had interruptions was at 33%. Conclusion: Drugs side effects, misconception, stigma, pill burden and migration were cited among influencing reasons for PrEP interruptions. Recommendations: Interventional study recommended to explore on the reasons cited for PrEP discontinuity in reaching PrEP goals in prevention services

Development and Deployment of the OpenMRS-Ebola Electronic Health Record System for an Ebola Treatment Center in Sierra Leone.

BACKGROUND: Stringent infection control requirements at Ebola treatment centers (ETCs), which are specialized facilities for isolating and treating Ebola patients, create substantial challenges for recording and reviewing patient information. During the 2014-2016 West African Ebola epidemic, paper-based data collection systems at ETCs compromised the quality, quantity, and confidentiality of patient data. Electronic health record (EHR) systems have the potential to address such problems, with benefits for patient care, surveillance, and research. However, no suitable software was available for deployment when large-scale ETCs opened as the epidemic escalated in 2014. OBJECTIVE: We present our work on rapidly developing and deploying OpenMRS-Ebola, an EHR system for the Kerry Town ETC in Sierra Leone. We describe our experience, lessons learned, and recommendations for future health emergencies. METHODS: We used the OpenMRS platform and Agile software development approaches to build OpenMRS-Ebola. Key features of our work included daily communications between the development team and ground-based operations team, iterative processes, and phased development and implementation. We made design decisions based on the restrictions of the ETC environment and regular user feedback. To evaluate the system, we conducted predeployment user questionnaires and compared the EHR records with duplicate paper records. RESULTS: We successfully built OpenMRS-Ebola, a modular stand-alone EHR system with a tablet-based application for infectious patient wards and a desktop-based application for noninfectious areas. OpenMRS-Ebola supports patient tracking (registration, bed allocation, and discharge); recording of vital signs and symptoms; medication and intravenous fluid ordering and monitoring; laboratory results; clinician notes; and data export. It displays relevant patient information to clinicians in infectious and noninfectious zones. We implemented phase 1 (patient tracking; drug ordering and monitoring) after 2.5 months of full-time development. OpenMRS-Ebola was used for 112 patient registrations, 569 prescription orders, and 971 medication administration recordings. We were unable to fully implement phases 2 and 3 as the ETC closed because of a decrease in new Ebola cases. The phase 1 evaluation suggested that OpenMRS-Ebola worked well in the context of the rollout, and the user feedback was positive. CONCLUSIONS: To our knowledge, OpenMRS-Ebola is the most comprehensive adaptable clinical EHR built for a low-resource setting health emergency. It is designed to address the main challenges of data collection in highly infectious environments that require robust infection prevention and control measures and it is interoperable with other electronic health systems. Although we built and deployed OpenMRS-Ebola more rapidly than typical software, our work highlights the challenges of having to develop an appropriate system during an emergency rather than being able to rapidly adapt an existing one. Lessons learned from this and previous emergencies should be used to ensure that a set of well-designed, easy-to-use, pretested health software is ready for quick deployment in future

Modelling study of the ability to diagnose acute rheumatic fever at different levels of the Ugandan healthcare system.

OBJECTIVE: To determine the ability to accurately diagnose acute rheumatic fever (ARF) given the resources available at three levels of the Ugandan healthcare system. METHODS: Using data obtained from a large epidemiological database on ARF conducted in three districts of Uganda, we selected variables that might positively or negatively predict rheumatic fever based on diagnostic capacity at three levels/tiers of the Ugandan healthcare system. Variables were put into three statistical models that were built sequentially. Multiple logistic regression was used to estimate ORs and 95% CI of predictors of ARF. Performance of the models was determined using Akaike information criterion, adjusted R2, concordance C statistic, Brier score and adequacy index. RESULTS: A model with clinical predictor variables available at a lower-level health centre (tier 1) predicted ARF with an optimism corrected area under the curve (AUC) (c-statistic) of 0.69. Adding tests available at the district level (tier 2, ECG, complete blood count and malaria testing) increased the AUC to 0.76. A model that additionally included diagnostic tests available at the national referral hospital (tier 3, echocardiography, anti-streptolysin O titres, erythrocyte sedimentation rate/C-reactive protein) had the best performance with an AUC of 0.91. CONCLUSIONS: Reducing the burden of rheumatic heart disease in low and middle-income countries requires overcoming challenges of ARF diagnosis. Ensuring that possible cases can be evaluated using electrocardiography and relatively simple blood tests will improve diagnostic accuracy somewhat, but access to echocardiography and tests to confirm recent streptococcal infection will have the greatest impact

HIV treatment outcomes and their associated factors among adolescents and youth living with HIV in Tanzania

Introduction:&nbsp; Despite improvements in access to Ante-Retroviral therapy in Tanzania, low ART initiation rate, low retention rate, lower viral load suppression, high loss to follow up and death rate among adolescents and youth living with HIV remain a challenge.&nbsp; This study was conducted to identify factors affecting HIV treatment outcomes among adolescents and youths. Methods: A cross-sectional study was done in seven regions in Tanzania. A total of 1124 in and out of school ALYHIV were interviewed using a semi-structured questionnaire. Results: A total of 1120(99.6%) participants were on ART. Of those who were on ART, 606 (53.9%) participants had advanced HIV disease, 423(37.6 %) had switched to the second line of ART and 1761(7.7%) had a virological failure. After adjusting for confounders, death of both parents (APR= 1.3, 95%CI: 1.01-1.8); regions with high HIV prevalence (APR= 1.7, 95%CI: 1.2-2.3) and taking ARVs for three years and less (APR= 2.2, 95%CI: 1.4-3.6) were associated to have advanced HIV. Additionally, HIV regional prevalence level, level of perception, adherence status, ARV storage and supervision of ART use were independently associated with Virological failure. &nbsp;&nbsp; Conclusion: This study has shown that despite an almost universal utilization of ART among adolescents and youth living with HIV unfavourable clinical ART outcomes such as advanced HIV disease, virological failure and ART switch to the second line remain a challenge, particularly among males and adolescents. Various factors at individual, community and health facility levels contribute to unfavorable ART clinical outcomes among AYLHIV. Therefore, an all-inclusive multidimensional and multi- stakeholders’ approach is needed to ensure the availability of sustainable, effective and quality care and treatment services prioritizing AYLHIV.&nbsp

Prevalence and incidence rate of tuberculosis among HIV-infected patients enrolled in HIV care, treatment, and support program in mainland Tanzania.

BACKGROUND: Despite improvements in access to antiretroviral therapy (ART), mortality in people living with human immunodeficiency virus (PLHIV) is still high and primarily attributed to tuberculosis (TB) infection. In Sub-Saharan Africa, approximately 80% of HIV-related mortality cases are associated with TB. Relatively little is known about the incidence of TB among PLHIV in Tanzania and the determinant factors. We report the prevalence and incidence rate of confirmed TB and determine association with selected demographic and program-related factors based on data in the national HIV care and treatment program from 2011 to 2014. METHODS: We used the Tanzania National AIDS Control Programme database to obtain information on all HIV clients enrolled in the HIV care and treatment program between January 2011 and December 2014. We analyzed retrospective cohort data to assess the prevalence and TB incidence rate per 1000 person-years. A multivariable Cox proportional hazards regression model was used to estimate hazard ratios and 95% confidence intervals for putatively associated factors. RESULTS: Over 4 years, there were 22,071 confirmed cases of pulmonary TB in 1,323,600 person-years. The overall TB incidence was around 16.7 (95% CI 16.4-16.9) cases per 1000 person-years. The annual incidence rate decreased by 12.4 % from 17.0 (95% CI 16.5-17.4) in 2011 to 14.9 (95% CI 14.5-15.4) in 2014. The TB incidence rate was higher in persons not using ART and in males than in females. The incidence of TB was higher in patients with advanced HIV disease and decreased with increasing age. The overall prevalence of TB was 2.2%, with a peak prevalence of 2.5% in 2013 and was higher among children < 15 years (3.2%) in the same year. CONCLUSION: The study found an overall decrease in the incidence of TB in PLHIV. Our results emphasize the need for early initiation of ART and the provision of TB preventive therapy for those PLHIV without active TB after intensified TB case-finding

World Heart Federation Roadmap on Atrial Fibrillation - A 2020 Update

The World Heart Federation (WHF) commenced a Roadmap initiative in 2015 to reduce the global burden of cardiovascular disease and resultant burgeoning of healthcare costs. Roadmaps provide a blueprint for implementation of priority solutions for the principal cardiovascular diseases leading to death and disability. Atrial fibrillation (AF) is one of these conditions and is an increasing problem due to ageing of the world’s population and an increase in cardiovascular risk factors that predispose to AF. The goal of the AF roadmap was to provide guidance on priority interventions that are feasible in multiple countries, and to identify roadblocks and potential strategies to overcome them. Since publication of the AF Roadmap in 2017, there have been many technological advances including devices and artificial intelligence for identification and prediction of unknown AF, better methods to achieve rhythm control, and widespread uptake of smartphones and apps that could facilitate new approaches to healthcare delivery and increasing community AF awareness. In addition, the World Health Organisation added the non-vitamin K antagonist oral anticoagulants (NOACs) to the Essential Medicines List, making it possible to increase advocacy for their widespread adoption as therapy to prevent stroke. These advances motivated the WHF to commission a 2020 AF Roadmap update. Three years after the original Roadmap publication, the identified barriers and solutions were judged still relevant, and progress has been slow. This 2020 Roadmap update reviews the significant changes since 2017 and identifies priority areas for achieving the goals of reducing death and disability related to AF, particularly targeted at low-middle income countries. These include advocacy to increase appreciation of the scope of the problem; plugging gaps in guideline management and prevention through physician education, increasing patient health literacy, and novel ways to increase access to integrated healthcare including mHealth and digital transformations; and greater emphasis on achieving practical solutions to national and regional entrenched barriers. Despite the advances reviewed in this update, the task will not be easy, but the health rewards of implementing solutions that are both innovative and practical will be great
