Background:The aim of this study was to assess the association of triglyceride-glucose (TyG) index with glycated haemoglobin (HbA1c) and insulin resistance in type 2 diabetes mellitus (T2DM).Methods: A total of 140 patients with T2DM were included in this cross-sectional study and divided into two groups according to their HbA1c levels: participants with HbA1c <7.0% (n=75) and those with HbA1c >7.0% (n=65) were defined as having a good glycemic control (group I) and a poor glycaemic control (group II) in T2DM. Anthropometric and biochemical parameters were measured, while the values of triglyceride (TG) to high density lipoprotein cholesterol (HDL-C) (TG/HDL-C) ratio and TyG index were calculated using formula.Results: Body mass index (BMI), fasting blood glucose (FBS), HbA1c and homeostatic model assessment for insulin resistance (HOMA-IR) were significantly higher in diabetic patients with poor glycemic control. TyG index was significantly correlated with HbA1c, HOMA-IR, TyG-BMI and TyG-WC. The receiver operating characteristic (ROC) analysis showed that TyG had a maximum area under the curve of 0.806, with a cut off value of 15.5 for identifying glycemic control in diabetic patients.Conclusion: TyG index is a useful tool for assessing glycemic control in T2DM patients and positively correlated with HbA1c and HOMA-IR. Hence, TyG can be used as a simple and inexpensive alternative to assess glycemic control in patients with diabetes.
BACKGROUND Periodontal disease is a chronic inflammatory disease of gum which surrounds and supports the teeth. Globally, periodontal disease is one of the most common oral diseases. Unhealthy periodontium has been connected to systemic conditions like pulmonary and cardiovascular diseases. Periodontal disease affects individuals of all ages, but it is most commonly seen in elderly patients. According to the World Health Organization, nearly 65 % of people have respiratory problems due to periodontal disease. Peak Expiratory Flow Rate (PEFR) is defined as the maximum rate and speed of expiration of an individual. We wanted to determine and compare PEFR in acute and chronic periodontitis. METHODS The present case control study was carried out among patients in the 20 - 40 years age group, who were attending outpatient department of Saveetha Dental College and Hospitals. Study participants were grouped into three categories as ‘normal individuals’, ‘patients with acute periodontitis’ and ‘patients with chronic periodontitis’; each group had 20 people. Spirometer was used to detect the peak expiratory flow rate. Statistical analysis was done using SPSS. P value of less than or equal to 0.05 was taken as statistically significant. RESULTS Results were obtained and expressed as mean ± SD. The Tukey HSD Post-hoc Test was used. Significance value is < 0.05. PEFRs are 420 ± 21.37 and 317 ± 21.05 in control and periodontitis individuals, respectively. P values for these criteria were < 0.05. Males have a high PEFR when compared to females in normal individuals group. This difference was statistically not significant. Females have a high PEFR when compared to males in patients with acute periodontitis. This difference was statistically not significant. Males have a high PEFR when compared to females with chronic periodontitis. When compared within and between groups, it was statistically significant (p = 0.0001). CONCLUSIONS Periodontitis could be a key source of respiratory disorders. This study shows that acute periodontitis expiratory flow rate was greater than chronic periodontitis expiratory flow rate. Proper maintenance of oral health and early detection of periodontitis may aid in reducing the frequency of respiratory problems due to periodontitis. KEY WORDS Acute Periodontitis, Chronic Periodontitis, Peak Flow Meter, Respiratory Disease
