Effects of Yoga on Blood Glucose and Lipid Profile of Type 2 Diabetes Patients Without Complications: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Type II diabetes mellitus (T2DM) has become a worldwide public health problem. Although it has been empirically established that physical activity is a promising therapeutical approach to the prevention and management of T2DM, the effectiveness of yoga on T2DM has not yet reached an agreement across studies and also needs an updated synthetic examination.

Purpose

The purpose of this study was to examine the effect of yoga training on diabetes-related indicators compared with usual care.

Methods

The review protocol of this study has been registered in the PROSPERO with a registration number CRD42021267868. A systematic literature search through electronic databases was conducted to identify yoga-based intervention (i.e., randomized controlled trial [RCT]; e.g., yogic postures, movements, breathing, and meditation) studies reporting outcomes on glycosylated hemoglobin (HbA1c), fasting blood glucose (FBG), postprandial blood glucose (PPBG), total cholesterol (TC), triglycerides (TG), and body mass index (BMI). A number of two researchers manually reviewed and assessed each article using the Cochrane Risk of Bias Tool 2.0. The literature search identified 296 eligible entries, of which 13 were finalized after screening using predefined inclusion and exclusion criteria. The extracted data (group mean and standard deviation at posttest) were synthesized using random-effects meta-analyses. Finally, potential moderators were explored using subgroup analysis and sensitivity analysis.

Results

The standardized mean difference for the effects of yoga was significant on HbA1c (MD = -0.47; 95%CI: -0.77, -0.16; Z = 3.02, p = 0.003), FBG (SMD = -0.92; 95%CI: -1.55, -0.29; Z = 2.87, p = 0.004), PPBG (SMD = -0.53; 95%CI: -0.86, -0.21; Z = 3.20, p = 0.001), and TG (SMD = -0.32; 95%CI: -0.54, -0.10; Z = 2.86, p = 0.004). However, yoga effect was not observed on TC (SMD = -0.84; 95%CI: -1.71, 0.04; Z = 1.87, p = 0.06) and BMI (MD = -0.63; 95%CI: -1.42, 0.16; Z = 1.57, p = 0.12).

Conclusion

The findings suggest that yoga can improve the biochemical indices of blood glucose and the lipid profile of patients with T2DM. Therefore, yoga can be prescribed as an effective and active complementary treatment for T2DM. However, this study only tested yoga as a short-term treatment. In the future, rigorous RCTs with a larger sample size may be carried out to examine the long-term effect of yoga on T2DM.

Project description:BackgroundDiabetes complications are the leading cause of mortality in diabetic patients. The common complications are decline in antioxidant capacity and the onset of micro-inflammation syndrome. At present, glucose-responsive nanoparticles are widely used, as they can release insulin-loaded ultrafine particles intelligently and effectively reduce blood sugar. However, the toxicology of this method has not been fully elucidated. The plant extracts of pterostilbene (PTE) have a wide range of biological applications, such as antioxidation and inflammatory response improvement. Therefore, we have proposed new ideas for the cross application of plant extracts and biomaterials, especially as part of a hypoglycaemic nano-drug delivery system.ResultsBased on the PTE, we successfully synthesised poly(3-acrylamidophenyl boric acid-b-pterostilbene) (p[AAPBA-b-PTE]) nanoparticles (NPs). The NPs were round in shape and ranged between 150 and 250 nm in size. The NPs possessed good pH and glucose sensitivity. The entrapment efficiency (EE) of insulin-loaded NPs was approximately 56%, and the drug loading (LC) capacity was approximately 13%. The highest release of insulin was 70%, and the highest release of PTE was 85%. Meanwhile, the insulin could undergo self-regulation according to changes in the glucose concentration, thus achieving an effective, sustained release. Both in vivo and in vitro experiments showed that the NPs were safe and nontoxic. Under normal physiological conditions, NPs were completely degraded within 40 days. Fourteen days after mice were injected with p(AAPBA-b-PTE) NPs, there were no obvious abnormalities in the heart, liver, spleen, lung, or kidney. Moreover, NPs effectively reduced blood glucose, improved antioxidant capacity and reversed micro-inflammation in mice.Conclusionsp(AAPBA-b-PTE) NPs were successfully prepared using PTE as raw material and effectively reduced blood glucose, improved antioxidant capacity and reduced the inflammatory response. This novel preparation can enable new combinations of plant extracts and biomaterials to adiministered through NPs or other dosage forms in order to regulate and treat diseases.

Project description:PurposePrior systematic reviews on yoga and diabetes have given conflicting results. They have been limited by inclusion of uncontrolled unblinded single group observational studies. No reviews are available which have used the Cochrane methodology and GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach. This meta-analysis evaluated the efficacy of yoga on glycaemia and lipids in T2DM using the Cochrane methodology and GRADE approach.MethodsMajor repositories were searched to pick randomized controlled trials involving T2DM patients receiving yoga. Primary outcome was to evaluate changes in fasting plasma glucose (FPG) and glycated haemoglobin (HbA1c). Secondary outcomes were to evaluate changes in post-prandial plasma glucose (PPG), total cholesterol (TC), triglycerides, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). Sub-group analysis involving people undergoing structured exercise regimen (SER) versus those undergoing standard diabetes care in controls was done.ResultsData from 13 studies involving 1440 patients were analysed. Compared to controls, individuals doing yoga had significantly lower FPG [mean difference (MD) -17.22 mg/dl (95% CI: -26.19 - -8.26 mg/dl); p < 0.01; considerable heterogeneity (CH); low certainty of evidence (LCE)], PPG [MD -27.77 mg/dl (95% CI: -35.73 - -19.81 mg/dl); p < 0.01; low heterogeneity; moderate certainty of evidence (MCE)], TC [MD -19.48 mg/dl (95% CI: -31.97 - -6.99 mg/dl); p < 0.01; CH; LCE], triglycerides [MD -12.99 mg/dl (95% CI: -23.74 - -2.25 mg/dl); p < 0.01; CH; LCE], LDL-C [MD -11.71 mg/dl (95% CI: -17.49 - -5.93 mg/dl); p < 0.01; I2 = 69% CH; LCE] and significantly higher HDL-C [MD 4.58 mg/dl (95% CI: 3.98-5.18 mg/dl); p < 0.01; low heterogeneity; MCE]. On sub-group analysis, where yoga was compared to SER, FPG was significantly lower in yoga group.ConclusionYoga improves glycaemia and lipid parameters in T2DM with additional benefits seen both in people doing/not doing structured exercise.Supplementary informationThe online version contains supplementary material available at 10.1007/s40200-021-00751-0.

Project description:The effects of camel milk (CM) intake on lipid profile among patients with diabetes remain controversial. This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to calculate the effect size of CM intake on blood lipids among patients with type 1 (T1D) and type 2 (T2D) diabetes. We searched nine databases from inception until December 31, 2022, to identify relevant RCTs. Effect sizes for total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), and high-density lipoprotein (HDL) were calculated and expressed using mean differences (MD) and confidence intervals (CI). Of 4,054 retrieved articles, 10 RCTs (a total of 347 participants aged 8-70 years, 60.5% male) were eligible for inclusion. The pooled results from a random-effects model showed statistically significant decreases in TC (MD - 21.69, 95% CI: 41.05, - 2.33; p = 0.03; I2=99%), TG (MD - 19.79, 95% CI: -36.16, - 3.42; p=0.02, I2=99%), and LDL (MD -11.92, CI: -20.57, -3.26; p = 0.007, I2=88%), and a significant increase in HDL (MD 10.37, 95% CI, 1.90, 18.84; p=0.02, I2=95%) in patients with diabetes supplemented with CM compared with usual care alone. Subgroup analysis revealed that only long-term interventions (> 6 months) elicited a significant reduction in TC levels and TG levels. Consumption of fresh CM by patients with diabetes resulted in significant reductions in TC, TG, and LDL levels, while showing a significant increase in HDL levels. Patients with T1D elicited a more beneficial effect in lowering TC, LDL, and TG levels and in increasing HDL levels than their corresponding partners with T2D. In conclusion, long-term consumption of CM for patients with diabetes, especially those with T1D, could be a useful adjuvant therapy to improve lipid profile alongside prescribed medications. However, the high heterogeneity in the included studies suggests that more RCTs with larger sample sizes and longer intervention durations are required to improve the robustness of the available evidence.
