Characterization of Individualized Glycemic Excursions during a Standardized Bout of Hypoglycemia-Inducing Exercise and Subsequent Hypoglycemia Treatment-A Pilot Study.

The glycemic response to ingested glucose for the treatment of hypoglycemia following exercise in type 1 diabetes patients has never been studied. Therefore, we aimed to characterize glucose dynamics during a standardized bout of hypoglycemia-inducing exercise and the subsequent hypoglycemia treatment with the oral ingestion of glucose. Ten male patients with type 1 diabetes performed a standardized bout of cycling exercise using an electrically braked ergometer at a target heart rate (THR) of 50% of the individual heart rate reserve, determined using the Karvonen equation. Exercise was terminated when hypoglycemia was reached, followed by immediate hypoglycemia treatment with the oral ingestion of 20 g of glucose. Arterialized blood glucose (ABG) levels were monitored at 5 min intervals during exercise and for 60 min during recovery. During exercise, ABG decreased at a mean rate of 0.11 ± 0.03 mmol/L·min-1 (minimum: 0.07, maximum: 0.17 mmol/L·min-1). During recovery, ABG increased at a mean rate of 0.13 ± 0.05 mmol/L·min-1 (minimum: 0.06, maximum: 0.19 mmol/L·min-1). Moreover, 20 g of glucose maintained recovery from hypoglycemia throughout the 60 min postexercise observation window.

Prevalence of diabetes and prediabetes and its risk factors in adults aged 25-64 in the Czech Republic: A cross-sectional study.

AIMS: The aim of this study is to establish the prevalence of diabetes (DM) and prediabetes in the Czech population aged 25-64 years and to evaluate the relationships with various cardiometabolic, sociodemographic, and lifestyle risk factors. METHODS: This was an epidemiological study with a stratified, crosssectional, random sampling design. Sociodemographic, lifestyle, and anamnestic data were collected through interviewer-administered questionnaires, medical examination, and biochemical assays. RESULTS: Among the 1189 participants, 114 were diagnosed with DM (9.6%), 330 with prediabetes (27.8%) and 745 were non-diabetes/non-prediabetes individuals (62.7%). Logistic regression analysis showed that overweight, general and abdominal obesity, hypertension, and lower level of HDL (increased risk) significantly increased the risk of both prediabetes and DM, while living in the cities diminished risk of DM. Among lifestyle variables the significant increased risk of prediabetes and DM was found for smokers and ex-smokers. In other lifestyle variables (marijuana lifetime prevalence, physical activity and frequency of alcohol drinking) the significantly higher or lower risk for prediabetes or DM was not found. CONCLUSIONS: The study shows a high prevalence of DM and prediabetes in the Czech population of age between 25 and 64, providing data on their association with several risk factors.

Prevalence of Diabetes Mellitus among Roma Populations-A Systematic Review.

BACKGROUND: The aim of this study was to estimate the prevalence of diabetes mellitus in the Roma population and compare it to the prevalence in the Caucasian population. METHODS: Using the words "Roma", "Gypsies", "Romani", and "traveler" in combination with "diabetes, "metabolic syndrome", "cardiovascular disease" and "health status" we searched the MEDLINE, Pubmed and Scopus databases for articles in English that focused on the prevalence of diabetes mellitus among Roma populations published until December 2017. RESULTS: Five studies met the inclusion criteria. The results of four of them suggested a higher prevalence of diabetes among Romani compared to Caucasians but none of them reached the standards regarding representative samples and number of cases for a conclusive result. CONCLUSION: Although some of the existing studies suggest a substantial prevalence of diabetes among Roma populations and even a higher risk of developing diabetes for Roma persons compared to Caucasians, the number of published literature on this topic remains very low and insufficient in design and number of participants to draw any conclusions.
