Impact of a community-based exercise programme on physical fitness in middle-aged and older patients with type 2 diabetes

Objectives: Physical fitness is related to all-cause mortality, quality of life and risk of falls in patients with type 2 diabetes. This study aimed to analyse the impact of a long-term community-based combined exercise program (aerobic + resistance + agility/balance + flexibility) developed with minimum and low-cost material resources on physical fitness in middle-aged and older patients with type 2 diabetes. Methods: This was a non-experimental pre-post evaluation study. Participants (N = 43; 62.92 ± 5.92 years old) were engaged in a community-based supervised exercise programme (consisting of combined aerobic, resistance, agility/balance and flexibility exercises; three sessions per week; 70 min per session) of 9 months' duration. Aerobic fitness (6-Minute Walk Test), muscle strength (30-Second Chair Stand Test), agility/balance (Timed Up and Go Test) and flexibility (Chair Sit and Reach Test) were assessed before (baseline) and after the exercise intervention. Results: Significant improvements in the performance of the 6-Minute Walk Test (Δ = 8.20%, p < 0.001), 30-Second Chair Stand Test (Δ = 28.84%, p < 0.001), Timed Up and Go Test (Δ = 14.31%, p < 0.001), and Chair Sit and Reach Test (Δ = 102.90%, p < 0.001) were identified between baseline and end-exercise intervention time points. Conclusions: A long-term community-based combined exercise programme, developed with low-cost exercise strategies, produced significant benefits in physical fitness in middle-aged and older patients with type 2 diabetes. This supervised group exercise programme significantly improved aerobic fitness, muscle strength, agility/balance and flexibility, assessed with field tests in community settings.

Hypoglycemic treatment of diabetic patients in the Emergency Department

Objectives: To analyze if the hypoglycemic therapy prescribed in the Emergency Department adapts to the consensus recommendations available, as well as to assess its clinical impact. Methods: A descriptive observational study, which included patients awaiting hospital admission, who were in the Observation Ward of the Emergency Department and had been previously diagnosed with diabetes mellitus, and were receiving treatment with hypoglycemic drugs at home. The management of antidiabetic treatment and its clinical impact were assessed. Results: 78 patients were included. At admission to the Emergency Department, treatment was modified for 91% of patients, and omitted for 9%. The most prescribed treatment was sliding scale insulin (68%). The treatments prescribed coincided in a 16.7% with the recommendations by the Spanish Society of Emergency Medicine. After intervention by the Pharmacist, the omission descended to 1.3%, and the adaptation to the recommendations increased to 20.5%. Comparing patients whose treatment coincided with the recommendations and those who did not, the clinical impact was respectively: mean glycemia at 24 hours: 138.3 ± 49.5 mg/dL versus 182.7 ± 97.1 mg/dL (p = 0.688); mean rescues with insulin lispro: ± 1.6 versus 1.5 ± 1.8 (p = 0.293); mean units of insulin lispro administered: 4.6 ± 12.7 IU versus 6.6 ± 11.3 IU (p = 0.155). Conclusions: We found antidiabetic prescriptions to have a low adaptation to consensus recommendations. These results are in line with other studies, showing an abuse of sliding scale regimen as single hypoglycemic treatment.

Chromium supplementation in patients with type 2 diabetes and high risk of type 2 diabetes: a meta-analysis of randomized controlled trials

Introduction: Chromium is an essential trace mineral for carbohydrate and lipid metabolism, which is currently prescribed to control diabetes mellitus. Results of previous systematic reviews and meta-analyses of chromium supplementation and metabolic profiles in diabetes have been inconsistent. Aim: The objective of this meta-analysis was to assess the effects on metabolic profiles and safety of chromium supplementation in type 2 diabetes mellitus and cholesterol. Methods: Literature searches in PubMed, Scopus and Web of Science were made by use of related terms-keywords and randomized clinical trials during the period of 2000-2014. Results: Thirteen trials fulfilled the inclusion criteria and were included in this systematic review. Total doses of Cr supplementation and brewer's yeast ranged from 42 to 1,000 µg/day, and duration of supplementation ranged from 30 to 120 days. The analysis indicated that there was a significant effect of chromium supplementation in diabetics on fasting plasma glucose with a weighted average effect size of -29.26 mg/dL, p = 0.01, CI 95% = -52.4 to -6.09; and on total cholesterol with a weighted average effect size of -6.7 mg/dL, p = 0.01, CI 95% = -11.88 to -1.53. Conclusions: The available evidence suggests favourable effects of chromium supplementation on glycaemic control in patients with diabetes. Chromium supplementation may additionally improve total cholesterol levels.
