OBJECTIVE: This study assessed the relationship between the parameters of glycemic control, and zinc concentrations in blood and superoxide dismutase enzyme activity in type 2 diabetes patients. SUBJECTS AND METHODS: Seventy-three individuals, aged between 25 and 59 years, were divided into the experimental group (type 2 diabetes patients, n = 36) and control group (n = 37). Plasma and erythrocyte zinc concentrations, superoxide dismutase activity, and parameters of glycemic control were analyzed. RESULTS: Mean plasma zinc concentration was 74.1 ± 10.7 µg/dL and 68.8 ± 9.6 µg/dL, erythrocyte zinc concentration was 48.1 ± 9.5 µg/gHb and 41.2 ± 8.0 µg/gHb, and superoxide dismutase activity was 2248.9 ± 300.0 U/gHb and 2059.6 ± 285.4 U/gHb, in the experimental group and the control group, respectively (p < 0.05). CONCLUSION: Type 2 diabetes patients showed a positive response to oxidative stress due to adequate zinc concentration in blood and increased activity of superoxide dismutase, and the enzyme was influenced by serum insulin.

Background: Diabetes mellitus and periodontitis are common diseases, there is a two-way relationship between oral health and systemic disease. Periodontal treatment helps glycaemic control, and in contrast, glycaemic control can make periodontal status better. Aim: To assess the effect of periodontal treatment on glycemic control in type 2 diabetes mellitus (DM) patients Materials and Methods: Study design of clinical trials without control group, the sample included 50 type 2 diabetes patients with moderated periodontitis status. Patients received oral hygiene instructions, full-mouth scaling and root planing. Data collection included plaque index (PlI), gingival index (GI), probing pocket depth (PPD), clinical attachment levels (CAL), bleeding on probing (BOP) and glycated haemoglobin (HbA1c) were recorded at baseline and three month after treatment. Results: After 3-month treatment, there were a significant change in PlI, GI, PPD, CAL, BOP and HbA1c levels (p < 0.01). A statistically significant effect could be demonstrated for PlI, GI, PPD, CAL, BOP and HbA1c levels. Conclusion: The results of this study showed that non-surgical periodontal treatment is improved not only periodontal health and also glycaemic control in type 2 diabetes mellitus patients. Key words: Type 2 diabetes mellitus, periodontitis, glycemic control

BACKGROUND The COVID-19 pandemic has challenged the in-person-based self-management approach (i.e., face-to-face or group approach) of type 2 diabetes (T2D). Older adults with T2D, including Asian Americans (AAs), have experienced worsening of diabetes control due to various reasons, including uncertainty of continuous access to essential diabetes medications, devices, education, limited health literacy, as well as constant anxiety and stress. Hybrid clinical trials that incorporate virtual elements into the in-person-based study could provide these vulnerable populations with accessible and timely interventions OBJECTIVE The primary aims of this pilot study are to determine (1) the effect of personalized behavioral nutrition (PBN) intervention on glycemic control, weight control, and metabolites profiles; and (2) the acceptability of PBN. to enhance glycemic control using personalized behavioral nutrition. METHODS Participants will be recruited with a web-based registry, advertisements in ethnic newspapers, and social network services popular among AAs. A total of 60 AAs, aged 65 years or older, who are descendants of Chinese, Korean, or South Asian, and have a diagnosis of T2D will be randomized into two groups: a PBN group (n=30) and a control group (n=30). A 4-week PBN intervention comprises three components: 1) digital self-monitoring; 2) personal nutrition change goals and recommendations; and 3) diabetes nutrition educations. All participants will complete digital self-monitoring on diet, physical activity, and blood glucose. In addition, all participants will access an interactive digital platform to track their self-monitoring data and communicate with the research team. The effectiveness and acceptability of implementing the intervention will be assessed. RESULTS Funding support and institutional review board approval for this study have been secured. Data collection started in August 2020 and is ongoing. CONCLUSIONS To our knowledge, this is the first study to determine the effectiveness and acceptability of PBN utilizing a metabolomics approach and digital-assisted intervention with hybrid RCT among older AAs. The findings of this pilot study will inform the development of a full-scale PBN protocol and hybrid clinical trials that can be adapted for people with T2D in the ongoing pandemic.

Abstract Background The study objective was to evaluate the effects of professional continuous glucose monitoring (CGM) as an adjuvant educational tool for improving glycemic control in patients with type 2 diabetes (T2D). Methods We conducted a three-month quasi-experimental study with an intervention (IGr) and control group (CGr) and ex-ante and ex-post evaluations in one family medicine clinic in Mexico City. Participants were T2D patients with HbA1c > 8% attending a comprehensive diabetes care program. In addition to the program, the IGr wore a professional CGM sensor (iPro™2) during the first 7 days of the study. Following this period, IGr participants had a medical consultation for the CGM results and treatment adjustments. Additionally, they received an educational session and personalized diet plan from a dietitian. After 3 months, the IGr again wore the CGM sensor for 1 week. The primary outcome variable was HbA1c level measured at baseline and 3 months after the CGM intervention. We analyzed the effect of the intervention on HbA1c levels by estimating the differences-in-differences treatment effect (Diff-in-Diff). Additionally, baseline and three-month CGM and dietary information were recorded for the IGr and analyzed using the Student’s paired t-test and mixed-effects generalized linear models to control for patients’ baseline characteristics. Results Overall, 302 T2D patients participated in the study (IGr, n = 150; control, n = 152). At the end of the three-month follow-up, we observed 0.439 mean HbA1C difference between groups (p = 0.004), with an additional decrease in HbA1c levels in the IGr compared with the CGr (Diff-in-Diff HbA1c mean of − 0.481% points, p = 0.023). Moreover, compared with the baseline, the three-month CGM patterns showed a significant increase in the percentage of time in glucose range (+ 7.25; p = 0.011); a reduction in the percentage of time above 180 mg/dl (− 6.01; p = 0.045), a decrease in glycemic variability (− 3.94, p = 0.034); and improvements in dietary patterns, shown by a reduction in total caloric intake (− 197.66 Kcal/day; p = 0.0001). Conclusion Professional CGM contributes to reducing HbA1c levels and is an adjuvant educational tool that can improve glycemic control in patients with T2D.

Background: Type 2 diabetes mellitus (T2DM) is a chronic condition with an impairing effect on multiple organs. Numerous respiratory disorders have been observed in patients with T2DM. However, T2DM e ect on pulmonary function is ff inconclusive. Aims: In this study, we investigated the effect of T2DM on respiratory function and the correlation of glycemic control, diabetes duration and insulin intake. Methods: 1500 patients were recruited for this study, 560 having T2DM for at least a year were included in the final data, in addition to 540 healthy volunteers. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC), forced expiratory flow at 25-75% (FEF 25-75%), as well as FEV1/FVC ratio values were measured. Results: A two-sample t-test showed that z-scores produced by Al-Qerem et al.’s equations for FEV1, FVC, and FEF 25-75% were significantly lower for the T2DM group than the control group (p < 0.01). FEV1/FVC ratio in T2DM group were significantly higher (p < 0.01). Multiple linear regression analysis found that glycemic control represented by HbA1c as well as disease duration were negatively associated with pulmonary function (p < 0.01). However, insulin intake was found to have no significant correlation with the pulmonary function. Conclusion: T2DM was linked to reduced pulmonary function and was consistent with a restrictive ventilation pattern. HbA1c as well as disease duration were independent risk factors for reduced pulmonary function.

Cardiovascular disease is the leading cause of death in diabetes mellitus. Endothelial dysfunction is the first step in the development of atherosclerotic vascular lesions, which underlies cardiovascular pathology, and adhesion molecules secreted by the endothelium during inflammatory changes are involved in the progression of this lesion. The objective: the serum level of adhesive molecules (ІCAM-1, VCAM-1, Е-selectin) in hypertensive and non-hypertensive type 2 diabetes patients as a marker of endothelial dysfunction and its relationship with other risk factors for cardiovascular disease was studied. Materials and methods. We examined 64 patients with type 2 diabetes, which were divided into two subgroups: the first subgroup – 41 hypertensive type 2 diabetes patients (age – 53,56±7,14 years, BMI – 32,2±87,4; HbA1c – 9,97±2,02%), the second subgroup – 23 nonhypertensive type 2 diabetes patients (age – 50,5±4,92 years, BMI – 25,4±5,22; HbA1c – 9,09±1,95%). The control group included 18 people without diabetes with normal blood pressure (age – 50,72±6,98 years, BMI – 24,71±4,88; HbA1c – 5,26±0,42%). The serum level was determined by immunoenzyme assay. The significance of the difference between the mean values was determined by the t-Student test. Multifactor regression analysis was used to assess the relationships between the studied factors. Results. We revealed an increase of serum levels of ІCAM-1, VCAM-1, Е-selectin in hypertensive (+71,62%, +68,42%, +66,95%, respectively) and non-hypertensive type 2 diabetes patients (+46,17%, +62,79%, +42,85%, respectively) compared with the control group (p<0,01). The serum concentration of ІCAM-1, Е-selectin was higher in hypertensive type 2 diabetes patients compared to non-hypertensive type 2 diabetes patients (+17,27%, +16,86%, respectively, p<0,01). There was a significant effect of Hb1Ac, lipids, insulin resistance on the serum level of ІCAM-1, VCAM-1, Е-selectin (p<0,01). The corresponding regression equations are derived. Conclusion. There is an increase of serum level of ІCAM-1, VCAM-1, Е-selectin in hypertensive and non-hypertensive type 2 diabetes patients, which indicates the development of endothelial dysfunction. Hypertension, hyperglycemia, dyslipidemia and insulin resistance contribute to the development of these changes.

Background: Although previous studies suggested the protective effect of zinc for type-2 diabetes, the unitary causal effect remains inconclusive. Objective: We investigated the causal effect of zinc as a single intervention on glycemic control in type-2 diabetes patients, using a systematic review of RCTs and two-sample Mendelian randomization (MR). Methods: Four outcomes were identified: fasting blood glucose/fasting glucose, hemoglobin A1c (HbA1c), homeostasis model assessment of insulin resistance (HOMA-IR), and serum insulin/fasting insulin level. In the systematic review, four databases were searched up to June 2021. Results were synthesized through the random-effects meta-analysis. Single nucleotide polymorphisms (SNPs) that are independent and are strongly related to zinc supplements were selected from MR-base to perform the two-sample MR with inverse-variance weighted (IVW) coefficient. Results: In the systematic review, 14 trials were included. The zinc supplement led to a significant reduction in the post-trial mean of fasting blood glucose (mean difference (MD): -26.52, 95%CI: -35.13, -17.91), HbA1C (MD: -0.52, 95%CI: -0.90, -0.13), and HOMA-IR (MD: -1.65, 95%CI: -2.62, -0.68), compared to the control group. In the two-sample MR, zinc supplement with 2 SNPs associated with lower fasting glucose (IVW coefficient: -2.04, 95%CI: -3.26, -0.83), but not specified type-2 diabetes. Conclusion: Although the study was limited by the few trials (review) and SNPs (two-sample MR), we demonstrated that the single zinc supplementary improved glycemic control among type-2 diabetes patients with causal evidence to a certain extent.
