Background: Exercise is strongly recommended for the management of type 2 diabetes mellitus (T2DM). However, incomplete intervention reporting in clinical trials limits the replication of exercise protocols. As previously demonstrated by us for exercise and hypertension, the reporting quality might also be insufficient in studies on T2DM and exercise. Objective: To assess completeness of exercise intervention reporting in randomized controlled trials (RCTs) for T2DM. Methods: Two independent reviewers applied the Consensus on Exercise Reporting Template (CERT) and the template for intervention description and replication (TIDieR) to 23 exercise trials obtained from the most recent and frequently cited meta-analysis in current guidelines. The completeness of reporting was evaluated focusing on the F.I.T.T. components (frequency, intensity, time, type). Interrater agreement and associations with publication year and journal impact factor were examined. Results: Mean CERT score was 11/19 (range 5–17), and 8/12 (range 4-12) for TIDieR. F.I.T.T. components were almost completely described, whereas overall completeness of exercise reporting was 60% and 68% (CERT and TIDieR). Replication of each exercise of the respective program was not possible in 52% of interventions. The majority of items had excellent agreement. No associations with publication year or impact factor were found. Conclusion: Exercise interventions were not sufficiently reported in RCTs that currently guide clinical practice in T2DM. Replication in further studies or clinical practice is limited due to poor exercise description. We suggest the use of the more specific CERT for reporting results of exercise interventions. Further refinement for internal diseases is needed to better describe exercise interventions.

The effect of exercise intervention on balance capacity among type 2 diabetes mellitus (T2DM) patients has not been evaluated. The objective of this systematic review and meta-analysis is to investigate the effect of exercise intervention on balance capacity among T2DM patients compared to the control group (usual care, waitlist, no-treatment, education). We conducted a comprehensive literature search through PubMed, EMBASE, Physiotherapy Evidence Database (PEDro), Cochrane library, Web of Science (WOS) from inception to August 2020. The literature language was limited to English. Randomized controlled trials (RCTs) or quasi-experimental (Q-E) trials that examined the effect of exercise intervention on balance capacity among T2DM patients were included. We used the standard methods of meta-analysis to evaluate the outcomes of exercise intervention for balance capacity of T2DM patients. A total of 14 trials (11 RCTs and 3 Q-E trials) involving 883 participants were eligible. The meta-analysis of some studies demonstrated that exercise intervention could significantly improve Berg Balance Scale (BBS) (MD = 2.56; 95%CI [0.35, 4.77]; P = .02), SLST (Single Leg Stance Test) under the eyes-open (EO) condition (MD = 3.63; 95%CI [1.79, 5.47]; P = .0001) and eyes-close (EC) condition (MD = 0.41; 95%CI [0.10, 0.72]; P = .01) compared to control group. There was no significant difference in Time Up and Go Test (TUGT) (MD = −0.75; 95%CI [−1.69, 0.19]; P = .12) and fall efficacy (SMD = −0.44; 95%CI [−0.86, −0.01]; P = .05). Narrative review of some studies indicated that exercise intervention could improve postural stability measured by Sensory Organization Test (SOT) and Center of Pressure (COP) variables, etc. This systematic review and meta-analysis summarized that exercise intervention could improve balance capacity in T2DM patients. However, further studies with high quality are required to evaluate its effect.

Spices such as cinnamon (Cinnamomum Spp.) have been of interest due to their phytochemical composition that exert hypoglycemic effects with potential for management of type 2 diabetes mellitus (T2DM). We summarize data from 27 manuscripts that include, one book chapter, 3 review articles, 10 randomized controlled trials, 4 systematic reviews with meta-analysis, and 9 preclinical studies. The most frequently used cinnamon variety was Cinnamomum cassia rather than the Cinnamomum zeylanicum, whereas outcomes were defined as fasting blood glucose, glycated hemoglobin, and oral glucose tolerance test. A great variability in methodology such as different doses (from 120 mg to 6 g), duration of intervention, data retrieved and use of different concomitant medication, were found to be key aspects of most of trials and systematic reviews with meta-analysis available to date. Low quality studies have been made in most cases with a lot of heterogeneity clouding significance of results. More research needs to be done in order to yield accurate evidence for evidence-based recommendations. Its use is not currently a reliable nor advisable option for the treatment of T2DM.

Background:Studies pertaining to association of GSTM1 and GSTT1 null genotypes with risk of T2DM and its complications were often inconclusive, thus spurring the present study.Methods:Meta-analysis of 25 studies for evaluating the role of GSTM1/GSTT1 null polymorphisms in determining the risk for T2DM and 17 studies for evaluating the role of GSTM1/GSTT1 null polymorphisms in development of T2DM related complications were conducted.Results:Our study revealed an association between GSTM1 and GSTT1 null polymorphism with T2DM (GSTM1; OR=1.37;95% CI =1.10-1.70 and GSTT1; OR=1.29;95% CI =1.04-1.61) with an amplified risk of 2.02 fold for combined GSTM1-GSTT1 null genotypes. Furthermore, the GSTT1 null (OR=1.56;95%CI=1.38-1.77) and combined GSTM1-GSTT1 null genotypes (OR=1.91;95%CI=1.25- 2.94) increased the risk for development of T2DM related complications, but not the GSTM1 null genotype. Stratified analyses based on ethnicity revealed GSTM1 and GSTT1 null genotypes increase the risk for T2DM in both Caucasians and Asians, with Asians showing much higher risk of T2DM complications than Caucasians for the same. </P><P> Discussion: GSTM1, GSTT1 and combined GSTM1-GSTT1 null polymorphism may be associated with increased risk for T2DM; while GSTT1 and combined GSTM1-GSTT1 null polymorphism may increase the risk of subsequent development of T2DM complications with Asian population carrying an amplified risk for the polymorphism.Conclusion:Thus GSTM1 and GSTT1 null genotypes increases the risk for Type 2 diabetes mellitus alone, in combination or with regards to ethnicity.
