Assessment of the diagnostic accuracy of Vibrasense compared to a biothesiometer and nerve conduction study for screening diabetic peripheral neuropathy.

AIMS: Peripheral neuropathy is a common microvascular complication in diabetes and a risk factor for the development of diabetic foot ulcers and amputations. Vibrasense (Ayati Devices) is a handheld, battery-operated, rapid screening device for diabetic peripheral neuropathy (DPN) that works by quantifying vibration perception threshold (VPT). In this study, we compared Vibrasense against a biothesiometer and nerve conduction study for screening DPN. METHODS: A total of 562 subjects with type 2 diabetes mellitus underwent neuropathy assessments including clinical examination, 10-g monofilament test, VPT evaluation with Vibrasense and a standard biothesiometer. Those with an average VPT ≥ 15 V with Vibrasense were noted to have DPN. A subset of these patients (N = 61) underwent nerve conduction study (NCS). Diagnostic accuracy of Vibrasense was compared against a standard biothesiometer and abnormal NCS. RESULTS: Average VPTs measured with Vibrasense had a strong positive correlation with standard biothesiometer values (Spearman's correlation 0.891, P < 0.001). Vibrasense showed sensitivity and specificity of 87.89% and 86.81% compared to biothesiometer, and 82.14% and 78.79% compared to NCS, respectively. CONCLUSIONS: Vibrasense demonstrated good diagnostic accuracy for detecting peripheral neuropathy in type 2 diabetes and can be an effective screening device in routine clinical settings.

Integrated Yoga Practice in Cardiac Rehabilitation Program: A Randomized Control Trial.

Background: Coronary artery disease (CAD) is a detrimental noncommunicable disease, which is increasing due to sedentary lifestyle and urbanization in the young population. It is further elevated with risk factors such as stress, anxiety, depression, an increase in triglycerides, dyslipidemia, hyperglycemia, hypertension, and so on, which manifests as atherosclerotic disease. Yoga-based lifestyle intervention is a noninvasive effective treatment method to control and prevent cardiac risk factors in CAD patients. Yoga has been used in India as a therapeutic method to manage hypertension and other chronic disorders and is fast gaining popularity as an effective means for the alleviation of stress, improvement of fitness, and enhancement of well-being. This study aimed to determine the feasibility of introducing the integrated approach of yoga therapy (IAYT) in a cardiac rehabilitation center in India and understand its usefulness in improving the cardiac function and managing the cardiac risk factors in acute myocardial infarction patients with left ventricular dysfunction. Methods and Design: Cardiac patients were randomized to a yoga-practicing group (n = 33) and a control group (n = 33). The yoga-practicing group was instructed to attend three supervised IAYT classes 3 days per week for 12 weeks at the hospital yoga center. The control group received standard care that included pharmacologic treatment and the instructions of the cardiologist. The outcome measures were assessed at baseline (T1 = 0) and completion (T2 = 3 months). The primary outcome measure was the left ventricular ejection fraction (LVEF). Results: There was no statistically significant difference in LVEF (U = 420.500, p value = 0.218) between the two groups. However, the yoga-practicing group showed significant reduction in depression (Cardiac Depression Scale [CDS], U = 71, p value = 0.0), anxiety (Hamilton Anxiety Rating Scale [HAM-A], U = 128, p value = 0.0), and a significant increase in quality of life (QOL) scores (Duke Activity Status Index [DASI], U = 146, p value = 0.0; and metabolic equivalents (METs), U = 136, p value = 0.0) at 3 months compared to control. Overall, the CAD patients practicing yoga showed a favorable profile compared to control individuals on CDS, HAM-A, DASI, and MET outcomes. Control and yoga practicing groups did not differ significantly in the lipid levels. Conclusion: This study indicated that the integration of yoga practice in a cardiac rehabilitation program is feasible and has no added benefit in improving the cardiac function. However, the addition of yoga to cardiac rehabilitation may be beneficial in reducing depression and anxiety and improving QOL in patients.
