Comprehensive Approach for Managing the Older Person with Diabetes Mellitus

Evaluation of Turkey diabetes self-management education in geriatrics with type 2 diabetes

BACKGROUND

This study was conducted to evaluate the diabetes education efficiency of individuals over 65 years old in Turkey, which has the highest prevalence of diabetes in Europe.

METHODS

We retrospectively evaluated 320 patients who attended Turkey diabetes self-management group education program (TDSMEP) between 2016 and 2020 in a secondary hospital. Participants who have been followed up for a maximum of 9 months are grouped as over 65 years old and under.

RESULTS

Of the 320 patients, 114 formed the geriatric group and 206 the non-geriatric group. After the training, the number of patients who had HbA1c ≤7% increased significantly in both the geriatric (28.1%-45.6%) and non-geriatric (19.9%-42.2%) (p = 0.001) groups. After the training, similar HbA1c goals were achieved in the geriatric and non-geriatric groups. The most significant HbA1c decrease was observed at the 3rd month of follow-up and remained stable until the 9th month. In logistic regression analysis, the factors affecting HbA1c failure (HbA1c >7%) after training in the geriatric group were long diabetes duration (OR = 1.07, 95% CI = 1.02-1.13, p = 0.01), high basal HbA1c levels (OR = 1.31, 95% CI = 1.03-1.67, p = 0.03), and low education level (OR = 3.88, 95% CI = 1.54-9.76, p = 0.001).

CONCLUSIONS

This is the first study to evaluate the effectiveness of TDSMEP for geriatric individuals whose HbA1c ≤7% increased from 28% to 45.6% during follow-up after the training. TDSMEP is recommended for all adult age groups, regardless of age range.

Circular RNA and its mechanisms in disease: From the bench to the clinic

The emerging recognition of the functional roles of circular RNAs (circRNAs) has given rise to a new perspective regarding our understanding of cellular physiology and disease pathogenesis. Unlike linear RNAs, circRNAs are covalently closed continuous loops that act as gene regulators in mammals, and their sequence composition determines the mode of circRNA biogenesis. The availability and integrated use of advanced genome analysis platforms have allowed the identification of a large number of these molecules. Their high abundance, stability and evolutionary conservation among species endow circRNAs with numerous potential functions, such as acting as microRNA (miRNA) sponges or binding to RNA-associated proteins to form RNA-protein complexes that regulate gene transcription. Moreover, circRNAs have been shown to be expressed in a tissue-specific manner and in pathological conditions, which has stimulated significant interest in their role in human disease and cancer. In this concise review, we outline the characteristics, functions and mechanisms of action of circRNAs as well as their involvement in different diseases. Although their exact roles and mechanisms of gene regulation remain to be clarified, circRNAs have potential applications as disease biomarkers and novel therapeutic targets.
