Glimepiride Loaded Poly(D,L-lactide-co-glycolide) Microspheres Improve Osseointegration of Dental Implants in Type 2 Diabetic Rats

The patients with type 2 diabetes mellitus (T2DM) have high dental implant failure frequency. This study explores the function of glimepiride local delivery on dental implant osseointegration in diabetes animal. Glimepiride loaded PLGA microspheres were loaded on the surface of the dental implant, and transplanted into ten Goto-Kakizaki (GK) rats. Blood sugar level and Implant Stability Quotient (ISQ) were measured every week after surgery. Histological, osseointegration rate and bone-implant contact (BIC) rate analysis were performed to evaluate dental osseointegration. The results showed that Glimepiride loaded Poly-lactide-co-glycolide (PLGA) microspheres have sustained-release curve. The glimepiride group exhibited greater ISQ than the control group. The BIC rate of the control and glimepiride group was 44.60%±1.95% and 59.80%±1.79%, respectively. This study demonstrated that the glimepiride group has a significantly greater osseointegration rate than that of the control group. Thus, Glimepiride could provide an alternative drug release microspheres for enhance the dental implant osseointegration in diabetes patients.

Role of eNOS and TGFβ1 gene polymorphisms in the development of diabetic nephropathy in type 2 diabetic patients in South Indian population

Background Diabetic nephropathy is known to be a leading complication of diabetes mellitus, characterized by diverse aspects such as high urinary albumin level, elevated blood pressure, and genetic susceptibility leading to end-stage renal disease. The current study was carried out to investigate the association of eNOS and TGFβ1 gene polymorphisms in the progression of diabetic nephropathy among type 2 diabetic patients in the South Indian population. The eNOS and TGFβ1 genetic variants were genotyped in 280 T2DM patients, 140 with DN, 140 without DN, and 140 controls. Genotyping was performed using ARMS PCR and the genomic variants were confirmed by the Sanger sequencing method. Results A significant (p < 0.05) association was observed in the genotypic frequencies of eNOS (G > T) polymorphism in the T2DM patients with diabetic nephropathy when compared to controls. The frequency of TT (heterozygous) genotype was observed to increase in patients with type 2 diabetes and DN when compared to the diabetic patients without DN and controls. This indicates that diabetic patients with TT genotype are at an increased risk to develop DN. However, TGFβ1 (G > C) polymorphism did not show any association in the allele and genotypic frequencies with DN when compared with T2DM and controls. Conclusion The results of the study propose a strong influence of TT genotype of eNOS gene be significantly linked with diabetic nephropathy in T2DM patients. Whereas no association was examined concerning TGFβ1 gene polymorphism and DN. Nevertheless, large sample size studies are required to confirm the part of these genetic variants in the development of DN.

Prescription of Physical Activity by General Practitioners in Type 2 Diabetes: Practice and Barriers in French Guiana

BackgroundGeneral practitioners (GPs) are the major primary healthcare players in the management of type 2 diabetes. In addition to a well-balanced diet, physical activity (PA) appears as a necessary non-medicinal therapy in the management of diabetic patients. However, GPs emphasize several obstacles to its prescription. The aim of this study is to evaluate the practices, barriers, and factors favoring the prescription of PA in type 2 diabetic patients by GPs in French Guiana.MethodWe conducted a cross-sectional descriptive study using a questionnaire, designed to interview 152 French Guiana GPs and describe their practice in prescribing PA in type 2 diabetic patients.ResultsOur results revealed that the prescription of PA as a non-medicinal therapeutic choice in the management of type 2 diabetes was practiced by 74% of the French Guiana GPs. However, only 37% of GPs responded that they implemented the recommendations; indeed, only one-third knew about them. The majority of GPs were interested in PA training, but only 11% were actually trained in this practice. The lack of structure adapted to the practice of PA and the lack of awareness of the benefits of PA in metabolic pathology appeared as the main obstacles to PA prescription.ConclusionThis study highlights the importance of improving the training of GPs in the prescription of PA, the development of adapted PA structures, and collaboration between the different actors within the framework of the sport-health system in type 2 diabetes in French Guiana.

A phenomenological study on barriers of adherence to medical advice among type 2 diabetic patients

Background More than three decades of research and study for overcoming the problem of “non-acceptance/non-compliance” of patients has neither resolved nor reduced the severity of this problem. This phenomenological study aimed to identify barriers of adherence to medical advice among type 2 diabetic patients. Methods This study was a qualitative research using phenomenology approach, and the data were analyzed using content analysis approach. Participants were 69 type 2 diabetic patients covered by the diabetes unit of West and East Community Health Centers of Ahvaz, Iran. The views and attitudes of patients about the barriers of adherence to medical advice were elicited by conducting 20–45 min sessions of semi-structured interviews. Data analysis was performed following Colaizzi’s seven-step method. Results Barriers of adherence to medical advice were classified into systemic and individual barriers. Individual barriers included 11 codes and 5 categories, and systemic barriers contained within 5 codes and 3 categories. Physiologic and physical factors, financial problems, occupational factors, attitudinal problems and lack of knowledge, and social and family problems were identified as individual barriers. Systemic barriers included inadequate publicizing and limited notification, inadequate equipment and facilities, and poor inter-sectional coordination. Conclusions Generally, problems stated by diabetic patients at the individual level can partly be solved by training patients and the people around them. However, as for the systemic problems, it seems that solving the barriers of adherence to medical advice requires coordination with other organizations as well as intersection coordination. Overall, these problems require not only comprehensive health service efforts, but also the support of policymakers to resolve barriers at infrastructure level.
