Abstract
Background Cardiovascular autonomic neuropathy (CAN) is a debilitating complication of diabetes mellitus. To date, there is no systematic review on all the available drug treatments for CAN in diabetic patients, except for one review focusing on aldose reductase inhibitors. Objective To evaluate available drug treatment options for CAN in diabetic patients. Methods A systematic review was conducted with a search of CENTRAL, Embase, PubMed and Scopus from database inception till 14th May 2022. Randomised controlled trials (RCTs) of diabetic patients with CAN that investigated the effect of treatment on blood pressure, heart rate variability, heart rate or QT interval were included. Results Thirteen RCTs with a total of 724 diabetic patients with CAN were selected. There was a significant improvement in the autonomic indices of diabetic patients with CAN given angiotensin-converting enzyme inhibitor (ACEI) for 24 weeks (p<0.05) to two years (p<0.001), angiotensin-receptor blocker (ARB) for one year (p<0.05), single dose of beta blocker (BB) (p<0.05), omega-3 polyunsaturated fatty acids (PUFAs) for three months (p<0.05), alpha-lipoic acid (ALA) for four months (p < 0.05) to six months (p=0.048), vitamin B12 in combination with ALA, acetyl L‑carnitine (ALC), superoxide dismutase (SOD) for one year (p=0.001) and near significant improvement in the autonomic indices of diabetic patients with CAN given vitamin E for four months (p = 0.05) compared to the control group. However, there was no significant improvement in the autonomic indices of patients given vitamin B12 monotherapy (p ≥ 0.05). Conclusion ACEI, ARB, BB, ALA, omega-3 PUFAs, vitamin E, vitamin B12 in combination with ALA, ALC and SOD could be effective treatment options for CAN, while vitamin B12 monotherapy might be unlikely to be recommended for the treatment of CAN due to its lack of efficacy.

Abstract
OBJECTIVE In 2015, Mbarara University of Science and Technology was awarded the Mbarara University Research Training Initiative (MURTI) under grant number D43 TW010128 to build capacity of junior faculty to become the next generation of researchers in Africa. In this paper, we document the experiences and achievements of the research capacity building efforts at MUST. METHODS We conducted a descriptive evaluation study which involved document review and in-depth interviews. We used "Reach" and 'Effectiveness' from the RE-AIM framework to guide the document review, and the organizational theory of implementation effectiveness to guide the in-depth interviews. RESULTS In the MURTI program, we conducted 17 short courses between August 2015 and July 2021, a total of 6597 attendances were recorded. The most attended courses were responsible conduct of research (n = 826), qualitative research methods (n = 744), and data management (n = 613). Thirty-three fellows were recruited and funded to conduct mentored research leading to 48 publications and 14 extramural grant applications were yielded. From the in-depth interviews, the participants appreciated the research training program, the enhanced research skills attained, and the institutional capacity built. They attributed the success of the program to the training approach of using short courses, readiness of the junior faculty to change, and the supportive environment by the mentors and trainers in the program. CONCLUSION The D43 TW010128 research training grant-built capacity for the junior faculty at MUST, enhanced their research skills, promoted research capacity institutionally and provided career development for the junior faculty. This was possible due to the positive attitude of the junior faculty (organizational readiness) to change and the supportive environment (mentors and trainers) during implementation of the grant. These two factors provided a favorable institutional climate that guaranteed success of the funding goals.

Abstract
Cardiovascular autonomic neuropathy (CAN) is a debilitating condition that mainly occurs in long-standing type 2 diabetes patients but can manifest earlier, even before diabetes is diagnosed. CAN is a microvascular complication that results from lesions of the sympathetic and parasympathetic nerve fibers, which innervate the heart and blood vessels and promote alterations in cardiovascular autonomic control. The entire mechanism is still not elucidated, but several aspects of the pathophysiology of CAN have already been described, such as the production of advanced glycation end products, reactive oxygen species, nuclear factor kappa B, and pro-inflammatory cytokines. This microvascular complication is an important risk factor for silent myocardial ischemia, chronic kidney disease, myocardial dysfunction, major cardiovascular events, cardiac arrhythmias, and sudden death. It has also been suggested that, compared to other traditional cardiovascular risk factors, CAN progression may have a greater impact on cardiovascular disease development. However, CAN might be subclinical for several years, and a late diagnosis increases the mortality risk. The duration of the transition period from the subclinical to clinical stage remains unknown, but the progression of CAN is associated with a poor prognosis. Several tests can be used for CAN diagnosis, such as heart rate variability (HRV), cardiovascular autonomic reflex tests, and myocardial scintigraphy. Currently, it has already been described that CAN could be detected even during the subclinical stage through a reduction in HRV, which is a non-invasive test with a lower operating cost. Therefore, considering that diabetes mellitus is a global epidemic and that diabetic neuropathy is the most common chronic complication of diabetes, the early identification and treatment of CAN could be a key point to mitigate the morbidity and mortality associated with this long-lasting condition.

Postural changes in blood pressure among patients with diabetes attending a referral hospital in southwestern Uganda: a cross-sectional study. BMC Cardiovasc Disord 2021; 21:213. [PMID: 33906603 PMCID: PMC8077796 DOI: 10.1186/s12872-021-02022-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 04/19/2021] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Orthostatic hypotension (OH) and orthostatic hypertension (OHT) are often unrecognized in clinical care for diabetic individuals, yet they are associated with increased risk for adverse cardiovascular outcomes. We aimed to determine the prevalence of the abnormal orthostatic blood pressure (BP) responses, and associated factors among diabetic individuals in ambulatory care for diabetes in southwestern Uganda. METHODS We conducted a cross-sectional study among diabetic individuals aged 18-65 years at Mbarara Regional Referral Hospital, southwestern Uganda from November 2018 to April 2019. We obtained demographic and clinical data including a detailed medical history, and glycemic profile. BP measurements were taken in supine position and within 3 min of standing. We defined OH in participants with either ≥ 20 mmHg drop in systolic BP (SBP) or ≥ 10 mmHg drop in diastolic BP (DBP) after assuming an upright position. OHT was defined in participants with either a ≥ 20 mmHg rise in SBP, or ≥ 10 mmHg rise in DBP after assuming an upright position. Multivariate logistic regression was used to identify factors associated with OH and OHT. RESULTS We enrolled 299 participants, with a mean age of 50 years (SD ± 9.8), and mean HbA1c of 9.7% (SD ± 2.6); 70% were female. Of the 299 participants, 52 (17.4%; 95% CI 13.3-22.2%) met the definition of OH and 43 (14.4%; 95% CI 10.6-18.9%) were classified as having OHT. In multivariable models, factors associated with diabetic OH were older age (OR = 2.40 for 51-65 years vs 18-50 years, 95% CI 1.02-5.67, P = 0.046), diabetic retinopathy (OR = 2.51; 95% CI 1.14-5.53, P = 0.022), higher resting SBP ≥ 140 mmHg (OR = 3.14; 95% CI 1.31-8.7.56, P = 0.011), and history of palpitations (OR = 2.31; 95% CI 1.08-4.92, P = 0.031). Self-report of palpitations (OR = 3.14; 95% CI 1.42-6.95, P = 0.005), and higher resting SBP ≥ 140 mmHg (OR = 22.01; 95% CI 1.10-4.42, P = 0.043) were associated with OHT. CONCLUSION OH and OHT are common among diabetic individuals in ambulatory diabetes care in southwestern Uganda. Orthostatic BP measurements should be considered as part of routine physical examination to improve detection of OH and OHT, especially among older diabetics with complications of the disease. Future studies to assess the health and prognostic implications of OH and OHT among diabetics in the region are warranted.

Abstract
AIM We aimed to describe cardiac autonomic neuropathy in a group of young Cameroonians type 1 diabetic patients. PATIENTS AND METHODS We conducted a descriptive cross-sectional study including consenting patients with type 1 diabetes and without any other comorbidity, who were followed-up at the type 1 diabetic children's clinic at the Yaoundé central hospital. Cardiac autonomic neuropathy was diagnosed and stage using the five functional tests described by Ewang et al., and the heart rate variability assessment. RESULTS We included 60 with a mean age of 18.6±4.9 years, 38.3% of female and a mean duration of diabetes of 5.9±5.1 years. Cardiac autonomic neuropathy was present in 96.7% of participants. Early, confirmed and severe cardiac autonomic neuropathy were found respectively in 8.3%, 86.7% and 1.7% of the patients. The most frequent clinical signs were exercise intolerance, alternating constipation and diarrhea and resting tachycardia. CONCLUSION Cardiac autonomic neuropathy is common in young patients with type 1 diabetes. It is important to integrate the assessment of cardiac autonomic reflexes in type 1 diabetic patients' follow-up.

Abstract
INTRODUCTION most patients with diabetes mellitus are prone to uncontrolled blood pressures despite effective medical therapies; only about 30% of hypertensive patients have their blood pressures controlled. Poor control of hypertension is associated with increased risk for cardiovascular mortality and morbidity. We aimed to determine the prevalence and associated factors of uncontrolled hypertension among patients with type 2 diabetes mellitus (T2DM) attending ambulatory care at Mbarara Regional Referral Hospital, Southwestern Uganda. METHODS we conducted a cross-sectional study from January to April 2019, among hypertensive T2DM patients. We used a structured questionnaire to obtain data on socio-demographic and clinical characteristics. We defined uncontrolled hypertension in participants with blood pressure ≥140/90mmHg and performed binary logistic regression to determine factors associated with uncontrolled hypertension. RESULTS we analyzed data of 206 hypertensive participants with concomitant T2DM, with a median age of 54 (IQR, 49-60) years, and median duration of diabetes of 4 (IQR, 3-8) years; 71% were female. The prevalence of uncontrolled hypertension was 82.5% (170/206). Isolated systolic hypertension (aOR=7.58; 95%CI: 2.18-26.36, P=0.001) and left ventricular hypertrophy (LVH) (aOR=5.38; 95%CI: 1.11-26.10, P=0.037) were significantly associated with uncontrolled hypertension. CONCLUSION this study revealed a high prevalence of uncontrolled hypertension among T2DM patients in Southwestern Uganda. Isolated systolic hypertension and LVH were the key factors associated with uncontrolled hypertension. We recommend optimization therapy to reduce the burden of uncontrolled hypertension among patients with T2DM especially in those with isolated systolic hypertension, and left ventricular hypertrophy, who are at higher cardiovascular risk.
