Project description:IntroductionThough several lines of evidence support the utility of yoga-based interventions in diabetes prevention, most of these studies have been limited by methodological issues, primarily sample size inadequacy. Hence, we tested the effectiveness of yoga-based lifestyle intervention against diabetes risk reduction in multicentre, large community settings of India, through a single-blind cluster-randomized controlled trial, Niyantrita Madhumeha Bharat Abhiyan (NMB).Research design and methodsNMB-trial is a multicentre cluster-randomized trial conducted in 80 clusters [composed of rural units (villages) and urban units (Census Enumeration Blocks)] randomly assigned in a 1:1 ratio to intervention and control groups. Participants were individuals (age, 20-70 years) with prediabetes (blood HbA1c values in the range of 5.7-6.4%) and IDRS ≥ 60. The intervention included the practice of yoga-based lifestyle modification protocol (YLP) for 9 consecutive days, followed by daily home and weekly supervised practices for 3 months. The control cluster received standard of care advice for diabetes prevention. Statistical analyses were performed on an intention-to-treat basis, using available and imputed datasets. The primary outcome was the conversion from prediabetes to diabetes after the YLP intervention of 3 months (diagnosed based upon HbA1c cutoff >6.5%). Secondary outcome included regression to normoglycemia with HbA1c <5.7%.ResultsA total of 3380 (75.96%) participants were followed up at 3 months. At 3 months post-intervention, overall, diabetes developed in 726 (21.44%) participants. YLP was found to be significantly effective in halting progression to diabetes as compared to standard of care; adjusted RRR was 63.81(95% CI = 56.55-69.85). The YLP also accelerated regression to normoglycemia [adjusted Odds Ratio (adjOR) = 1.20 (95% CI, 1.02-1.43)]. Importantly, younger participants (≤40 years) were found to regress to normoglycemia more effectively than the older participants Pinteraction<0.001.ConclusionBased on the significant risk reduction derived from the large sample size, and the carefully designed randomized yoga-based intervention on high-risk populations, the study is a preliminary but strong proof-of-concept for yoga as a potential lifestyle-based treatment to curb the epidemic of diabetes. The observed findings also indicate a potential of YLP for diabetes prevention in low/moderate risk profile individuals that needs large-scale validation.Trial registrationClinical Trial Registration Number: CTRI/2018/03/012804.

Project description:PURPOSE:Thirty percent to 90% of cancer survivors report impaired sleep quality post-treatment, which can be severe enough to increase morbidity and mortality. Lifestyle interventions, such as exercise, are recommended in conjunction with drugs and cognitive behavioral therapy for the treatment of impaired sleep. Preliminary evidence indicates that yoga-a mind-body practice and form of exercise-may improve sleep among cancer survivors. The primary aim of this randomized, controlled clinical trial was to determine the efficacy of a standardized yoga intervention compared with standard care for improving global sleep quality (primary outcome) among post-treatment cancer survivors. PATIENTS AND METHODS:In all, 410 survivors suffering from moderate or greater sleep disruption between 2 and 24 months after surgery, chemotherapy, and/or radiation therapy were randomly assigned to standard care or standard care plus the 4-week yoga intervention. The yoga intervention used the Yoga for Cancer Survivors (YOCAS) program consisting of pranayama (breathing exercises), 16 Gentle Hatha and Restorative yoga asanas (postures), and meditation. Participants attended two 75-minute sessions per week. Sleep quality was assessed by using the Pittsburgh Sleep Quality Index and actigraphy pre- and postintervention. RESULTS:In all, 410 survivors were accrued (96% female; mean age, 54 years; 75% had breast cancer). Yoga participants demonstrated greater improvements in global sleep quality and, secondarily, subjective sleep quality, daytime dysfunction, wake after sleep onset, sleep efficiency, and medication use at postintervention (all P ? .05) compared with standard care participants. CONCLUSION:Yoga, specifically the YOCAS program, is a useful treatment for improving sleep quality and reducing sleep medication use among cancer survivors.

Project description:BackgroundTrauma is highly prevalent among vulnerable populations, including those who are incarcerated, in treatment for substance use, or seeking mental health services. Trauma-informed yoga seeks to create a safer yoga practice for individuals with a trauma history and may improve emotional and physical wellbeing. Thus, we conducted an evaluation of a trauma-informed yoga program to gain insight into participant experiences.MethodsTrauma-informed yoga classes were led by trained volunteers and held in three sectors that work with vulnerable populations: corrections and reentry, substance use treatment and recovery, and community and mental health. Data were collected via anonymous survey using a retrospective pre-post design. The survey instrument captured reasons for student participation and perceived effects of yoga on emotional and physical wellbeing.ResultsStudents were motivated to participate in yoga classes by expectations of physical, mental, and spiritual benefit. Students reported perceived improvements in emotional and physical wellbeing and greater use of self-regulation skills after starting yoga.ConclusionOur findings suggest trauma-informed yoga is perceived as beneficial by vulnerable individuals, especially those in the correctional system or recovering from substance use. Our results support the value of offering trauma-informed yoga in institutionalized and community settings. Improvements in emotional and physical wellbeing warrant formal study.

Project description:BACKGROUND: Intensive lifestyle intervention significantly reduces the progression to diabetes in high-risk individuals. OBJECTIVE: It is not known whether a program of moderate intervention might effectively reduce metabolic abnormalities in the general population. DESIGN: Two-arm randomized controlled 1-year trial. PATIENTS: Three hundred and thirty-five patients participated from a dysmetabolic population-based cohort of 375 adults aged 45-64 years in northwestern Italy. MEASUREMENTS: We compared the effectiveness of a general recommendation-based program of lifestyle intervention carried out by trained professionals versus standard unstructured information given by family physicians at reducing the prevalence of multiple metabolic and inflammatory abnormalities. RESULTS: At baseline, clinical/anthropometric/laboratory and lifestyle characteristics of the intervention (n = 169) and control (n = 166) groups were not significantly different. The former significantly reduced total/saturated fat intake and increased polyunsaturated fat/fiber intake and exercise level compared to the controls. Weight, waist circumference, high-sensitivity C-reactive protein, and most of the metabolic syndrome components decreased in the intervention group and increased in the controls after 12 months. Lifestyle intervention significantly reduced metabolic syndrome (odds ratio [OR] = 0.28; 95% CI 0.18-0.44), with a 31% (21-41) absolute risk reduction, corresponding to 3.2 (2-5) patients needing to be treated to prevent 1 case after 12 months. The intervention significantly reduced the prevalence of central obesity (OR = 0.33; 0.20-0.56), and hypertriglyceridemia (OR = 0.48; 0.31-0.75) and the incidence of diabetes (OR = 0.23; 0.06-0.85). CONCLUSION: A lifestyle intervention based on general recommendations was effective in reducing multiple metabolic/inflammatory abnormalities. The usual care by family physicians was ineffective at modifying progressive metabolic deterioration in high-risk individuals.

Project description:BackgroundMetabolic disorders are established precursors to cardiovascular diseases, yet they can be readily prevented with sustained lifestyle modifications.ObjectiveWe assessed the effectiveness of a smartphone-based weight management app on metabolic parameters in adults at high-risk, yet without physician diagnosis nor pharmacological treatment for metabolic syndrome, in a community setting.MethodsIn this 3-arm parallel-group, single-blind, randomized controlled trial, we recruited participants aged 30 to 59 years with at least 2 conditions defined by the Third Report of the National Cholesterol Education Program expert panel (abdominal obesity, high blood pressure, high triglycerides, low high-density lipoprotein cholesterol, and high fasting glucose level). Participants were randomly assigned (1:1:1) by block randomization to either the nonuser group (control), the app-based diet and exercise self-logging group (app only), or the app-based self-logging and personalized coaching from professional dieticians and exercise coordinators group (app with personalized coaching). Assessments were performed at baseline, week 6, week 12, and week 24. The primary outcome was change in systolic blood pressure (between baseline and follow-up assessments). Secondary outcomes were changes in diastolic blood pressure, body weight, body fat mass, waist circumference, homeostatic model of assessment of insulin resistance, triglyceride level, and high-density lipoprotein cholesterol level between baseline and follow-up assessments. Analysis was performed using intention-to-treat.ResultsBetween October 28, 2017 and May 28, 2018, 160 participants participated in the baseline screening examination. Participants (129/160, 80.6%) who satisfied the eligibility criteria were assigned to control (n=41), app only (n=45), or app with personalized coaching (n=43) group. In each group, systolic blood pressure showed decreasing trends from baseline (control: mean -10.95, SD 2.09 mmHg; app only: mean -7.29, SD 1.83 mmHg; app with personalized coaching: mean -7.19, SD 1.66 mmHg), yet without significant difference among the groups (app only: P=.19; app with personalized coaching: P=.16). Instead, those in the app with personalized coaching group had greater body weight reductions (control: mean -0.12, SD 0.30 kg; app only: mean -0.35, SD 0.36 kg, P=.67; app with personalized coaching: mean -0.96, SD 0.37 kg; P=.08), specifically by body fat mass reduction (control: mean -0.13, SD 0.34 kg; app only: mean -0.64, SD 0.38 kg, P=.22; app with personalized coaching: mean -0.79, SD 0.38 kg; P=.08).ConclusionsSimultaneous diet and exercise self-logging and persistent lifestyle modification coaching were ineffective in lowering systolic blood pressure but effective in losing weight and reducing body fat mass. These results warrant future implementation studies of similar models of care on a broader scale in the context of primary prevention.Trial registrationClinicalTrials.gov NCT03300271; http://clinicaltrials.gov/ct2/show/NCT03300271.

Project description:Amyotrophic lateral sclerosis (ALS) is a devastating disorder in which motor neurons degenerate, the causes of which remain unclear. In particular, the basis for selective vulnerability of spinal motor neurons (sMNs) and resistance of ocular motor neurons to degeneration in ALS has yet to be elucidated. Here, we applied comparative multi-omics analysis of human induced pluripotent stem cell-derived sMNs and ocular motor neurons to identify shared metabolic perturbations in inherited and sporadic ALS sMNs, revealing dysregulation in lipid metabolism and its related genes. Targeted metabolomics studies confirmed such findings in sMNs of 17 ALS (SOD1, C9ORF72, TDP43 (TARDBP) and sporadic) human induced pluripotent stem cell lines, identifying elevated levels of arachidonic acid. Pharmacological reduction of arachidonic acid levels was sufficient to reverse ALS-related phenotypes in both human sMNs and in vivo in Drosophila and SOD1G93A mouse models. Collectively, these findings pinpoint a catalytic step of lipid metabolism as a potential therapeutic target for ALS.

Project description:A majority of the cases of primary male infertility are idiopathic with the underlying molecular mechanisms contributing to the pathophysiology as yet unknown. Effects of the environment can alter the sperm epigenome thereby impacting male reproduc-tive health. Epigenetic mechanisms are crucial to understanding health and disease, and methylome alterations are now known to have far-reaching clinical implications. Here, we report the results from our pilot study, a first of its kind analysis of the ef-fect of the traditional practice of yoga on human sperm quality. We find marked im-provement in sperm characteristics in patients of idiopathic male infertility following asupervised21-dayyogaregimen.Furthermore,next-generationsequencing-basedmethylome analysis reveals alterations in the sperm epigenome of these patients. We find that the practice of yoga is associated with DNA methylation changes at nearly 400 genes, 147 of which were hypermethylated while 229 were hypomethyl-ated. These included promoters of several genes linked to maintenance of fertility and genomic integrity. This novel piece of work draws a direct link between positive lifestyle practices and male reproductive health.

Project description:BACKGROUND:Nutraceuticals represent a new therapeutic frontier in the treatment of metabolic syndrom (MetS) and related cardiovascular risk factors. The aim of this study was to evaluate the potential beneficial effects of Armolipid Plus (AP) (berberine 500?mg, red yest rice, monacolin K 3?mg and policosanol 10?mg) on insulin resistance, lipid profile, particularly on small and dense LDL cholesterol (sdLDL-C), representing the most atherogenic components, as well as its effects on high sensitivity C-reactive protein, a notable marker of cardiovascular risk, blood pressure and cardiac remodeling in subjects affected by MetS, with left ventricular hypertrophy. METHODS:The study was a prospective, multi-center, randomized, double blind, placebo-controlled trial. One hundred and fifty eight patients, aged between 28 and 76?years old, were enrolled and randomized to receive either one tablet of AP or placebo (PL) once daily for 24?weeks. Anthropometric and vital parameters, total cholesterol (tot-C), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), triglyceridemia (TG), non-HDL cholesterol (NHDL-C) and sdLDL-C were evaluated. RESULTS:After 24?weeks of treatment, the analysis performed on 141 subjects (71 in AP arm and 70 in PL arm), showed a significant improvement of lipid profile in the AP group, with reduction in tot-C (-?13.2?mg/dl), LDL-C (-?13.9?mg/dl) and NHDL-C (-?15.3?mg/dl) and increase in HDL-C (+?2.0?mg/dl). These changes were equally significant compared with placebo (tot-C: AP -?13.2?mg/dL vs PL?+?2.7?mg/dL, p?<?0.01; LDL-C: AP -13.9?mg/dl vs PL +?1.5?mg/dl, p?<?0.01; NHDL-C: AP -15.3?mg/dl vs PL +?2.8?mg/dl, p?<?0.01), Although no significant difference was observed between the two arms in the reduction of HDL-C nevertheless it increased significantly in the AP group (AP +?2?mg/dL p?<?0.05, PL 0.13?mg/dL). CONCLUSION:The results of this study, applicable to a specific local population show that, in a population of subjects affected by MetS, treatment with AP improves the lipid profile and the most atherogenic factors, thus suggesting a reduction in the risk of development and progression of atherosclerosis, particularly in subjects with high atherogenic risk, due to the presence of sdLDL-C.

Project description:The coronavirus disease 2019 (COVID-19) pandemic created significant psychological challenges worldwide, including stress, emotional distress, and insomnia. In addition, social distancing, travel restrictions, and spread of disease have resulted in unique challenges, creating barriers to healthcare access. Compared to the rate prior to the COVID-19 pandemic, a significant increase in clinical insomnia rates have been reported. With well-known limitations of currently established treatments (e.g., cognitive behavioral therapy-insomnia (CBT-I), pharmacotherapy), there is a need to explore other effective and safe treatment modalities to treat insomnia, especially those that can be used remotely. The purpose of this study is to assess the effectiveness of app-based intervention to treat insomnia in the current era of the COVID-19 pandemic (using the Yoga of Immortals (YOI) app). This prospective cohort study was approved by the Institutional Review Board. All participants in this study were asked to complete an online survey including demographic data and validated Insomnia Severity Index (ISI) at baseline (15 May 2020), 4 weeks, and 8 weeks after starting the YOI intervention. Survey data was exported using Microsoft Excel. Statistical analysis was done using the GraphPad Prism 8. YOI intervention significantly improved the mean ISI scores in all categories of insomnia (severe, moderate, and subthreshold) at each follow-up (p ≤ 0.0001). The improvement was significant among all age groups and in both genders. In our study, YOI was a novel and effective intervention for improving insomnia symptoms and may be a new addition to the armamentarium of insomnia management. Being app-based, this has potential wider applicability, especially during the current COVID-19 pandemic.
