Background: Glycemic control is the basis for managing diabetes to prevent chronic complications in diabetes. HbaA1c levels reaching ≤7% is an indicator of achieving good glycemic control. The 3J principles (right type, amount, and schedule) in the pillars of meal management are not easy to apply, causing diabetes to have difficulty achieving glycemic targets. Objectives: Analyzing rice portion restriction and pre-meal fruit with HbA1c levels and abdominal fat in people with diabetes in Malang City. Methods: Experimental study type 'randomized controlled trial' with pre-posttest control group design involved 16 people with diabetes who were active in Prolanis activities at the Malang city health center. Respondents were randomly divided into 2 groups. HbA1c levels were taken 2 times, before and after the intervention. The t test and paired t test with a pvalue<0.05 were used to test the effect of the intervention on HbA1c levels, abdominal fat and abdominal circumference in people with diabetes for 3 months. Results: Both forms of intervention can reduce HbA1c levels in diabetic patients. Limiting the portion of rice significantly reduced HbA1c levels (p=0.003) and visceral fat levels. However, determining the amount of rice with added pre-meal fruit did not significantly decrease visceral fat and abdominal circumference (p>0.05). Conclusions: Limiting the portion of rice eaten by itself or combining it with pre-meal fruit may help diabetics lower their HbA1c levels. [ABSTRACT FROM AUTHOR]

Background: Right ventricular (RV) involvement has been reported in type 2 diabetes mellitus (T2DM). The relationship between glycemic control and RV function remains unknown. We aimed to investigate the association between glycemic control and RV function assessed by two-dimensional speckle-tracking echocardiography and three-dimensional echocardiography in T2DM individuals., Methods: This study prospectively enrolled 207 patients with T2DM and 84 individuals with normal glucose metabolism. The T2DM patients were divided into 2 subgroups according to glycated hemoglobin (HbA1c) level: controlled (HbA1c < 7.0%, n = 91) and uncontrolled subgroup (HbA1c ≥ 7.0%, n = 116). Right venticular free wall longitudinal strain (RVFWLS) was acquired by two-dimensional speckle-tracking echocardiography, and RV volumes and RV ejection fraction (RVEF) were assessed using three-dimensional echocardiography . Right ventricular coupling to pulmonary circulation was defined as the ratio of RVFWLS/pulmonary artery systolic pressure (PASP)., Results: Controlled and uncontrolled T2DM subgroups had impaired RV function as reflected by reduced RVFWLS and RVEF compared to the normal glucose metabolism group. The reduction in RVFWLS was more pronounced in the uncontrolled subgroup than in the controlled subgroup (P < .001), whereas no significant difference was found in RVEF between these 2 T2DM subgroups. Higher PASP and lower RVFWLS/PASP ratio were also noted in uncontrolled T2DM patients. Additionally, the incidence of RV dysfunction was significantly higher in the uncontrolled T2DM patients than in the controlled subgroup (43.1% vs 17.6%, P < .001). After adjustment for potential clinical confounders, PASP, and left ventricular parameters, HbA1c level was independently associated with RVFWLS (β = 0.290, P = .003) and RVFWLS/PASP ratio (β = 0.028, P = .006)., Conclusions: Subclinical RV myocardial dysfunction is present in T2DM patients and is more pronounced in patients with uncontrolled blood glucose. HbA1c level is independently associated with subclinical RV myocardial dysfunction, providing further insight into a possible link between poor glycemic control and diabetic cardiomyopathy., Competing Interests: Conflicts of Interest None., (Copyright © 2024 American Society of Echocardiography.
