Assessment of Changes in Body Composition After 3 Months of Dulaglutide Treatment.

Changes in body composition accompanied by glucagon-like peptide 1 receptor agonist (GLP-1RA) induced weight loss have drawn much attention. However, fewer studies have reported body composition changes in patients receiving dulaglutide therapy in Chinese population. A total of 70 overweight/obese type 2 diabetes mellitus (T2DM) patients who received dulaglutide therapy were included. Clinical data were collected. Visceral fat area (VFA) and body composition were also measured. Changes in clinical indicators and body composition of patients before and after intervention were also analyzed. Correlation analysis and multiple linear regression model were used to evaluate the association between hemoglobin A1C (HbA1c) and body composition. The results showed that body weight (BW), VFA, body fat (BF), lean body mass (LBM), skeletal muscle mass (SMM) and water content were reduced after 3 months dulaglutide intervention. The lean body mass percentage (LBMP) and skeletal muscle mass percentage (SMMP) significantly increased. Moreover, there was no significant difference in bone mineral quality (BMQ) after the intervention. The multiple linear regression model revealed that the % change in BF was independently associated with % change in HbA1c (β = 0.449, t = 3.148, p=0.002). These results indicate that dulaglutide intervention does not cause muscle and bone mass loss while inducing weight loss, and % change in BF was independently associated with improved glucose control during dulaglutide therapy. This study offers some positive results to support the clinical application of dulaglutide.

Global, neuronal or β cell-specific deletion of inceptor improves glucose homeostasis in male mice with diet-induced obesity.

Insulin resistance is an early complication of diet-induced obesity (DIO)1, potentially leading to hyperglycaemia and hyperinsulinaemia, accompanied by adaptive β cell hypertrophy and development of type 2 diabetes2. Insulin not only signals via the insulin receptor (INSR), but also promotes β cell survival, growth and function via the insulin-like growth factor 1 receptor (IGF1R)3-6. We recently identified the insulin inhibitory receptor (inceptor) as the key mediator of IGF1R and INSR desensitization7. But, although β cell-specific loss of inceptor improves β cell function in lean mice7, it warrants clarification whether inceptor signal inhibition also improves glycaemia under conditions of obesity. We assessed the glucometabolic effects of targeted inceptor deletion in either the brain or the pancreatic β cells under conditions of DIO in male mice. In the present study, we show that global and neuronal deletion of inceptor, as well as its adult-onset deletion in the β cells, improves glucose homeostasis by enhancing β cell health and function. Moreover, we demonstrate that inceptor-mediated improvement in glucose control does not depend on inceptor function in agouti-related protein-expressing or pro-opiomelanocortin neurons. Our data demonstrate that inceptor inhibition improves glucose homeostasis in mice with DIO, hence corroborating that inceptor is a crucial regulator of INSR and IGF1R signalling.

Are insulin sensitizers the new strategy to treat Type 1 diabetes? A long-acting dual amylin and calcitonin receptor agonist improves insulin-mediated glycaemic control and controls body weight.

Insulin therapies for Type 1 diabetes (T1D) have limitations, such as glucose fluctuations, hypoglycaemia, and weight gain. Only pramlintide is approved with insulin. However, its short half-life limits efficacy, requiring multiple daily injections and increasing hypoglycaemia risk. New strategies are needed to improve glycaemic control. Dual amylin and calcitonin receptor agonists are potent insulin sensitizers developed for Type 2 diabetes (T2D) as they improve glucose control, reduce body weight, and attenuate hyperglucagonemia. However, it is uncertain if they could be used to treat T1D. Sprague Dawley rats received a single intravenous injection of streptozotocin (STZ) (50 mg·kg-1) to induce T1D. Humulin (1 U/200 g·day-1 or 2 U/200 g·day-1) was continuously infused, while half of the rats received additional KBP-336 (4.5nmol·kg-1 Q3D) treatment. Bodyweight, food intake, and blood glucose were monitored throughout the study. An oral glucose tolerance test was performed during the study. Treatment with Humulin or Humulin + KBP-336 improved the health of STZ rats. Humulin increased body weight in STZ rats, but KBP-336 attenuated these increases and maintained a significant weight loss. The combination exhibited greater blood glucose reductions than Humulin-treated rats alone, reflected by improved HbA1c levels and glucose control. The combination prevented hyperglucagonemia, reduced amylin levels, and increased pancreatic insulin content, indicating improved insulin sensitivity and beta-cell preservation. The insulin sensitizer KBP-336 lowered glucagon secretion while attenuating insulin-induced weight gain. Additionally, KBP-336 may prevent hypoglycaemia and improve insulin resistance, which could be a significant advantage for individuals with T1D seeking therapeutic benefits.

Beneficial effects of simultaneously targeting calorie intake and calorie efficiency in diet-induced obese mice.

Semaglutide is an anti-diabetes and weight loss drug that decreases food intake, slows gastric emptying, and increases insulin secretion. Patients begin treatment with low-dose semaglutide and increase dosage over time as efficacy plateaus. With increasing dosage, there is also greater incidence of gastrointestinal side effects. One reason for the plateau in semaglutide efficacy despite continued low food intake is due to compensatory actions whereby the body becomes more metabolically efficient to defend against further weight loss. Mitochondrial uncoupler drugs decrease metabolic efficiency, therefore we sought to investigate the combination therapy of semaglutide with the mitochondrial uncoupler BAM15 in diet-induced obese mice. Mice were fed high-fat western diet (WD) and stratified into six treatment groups including WD control, BAM15, low-dose semaglutide without or with BAM15, and high-dose semaglutide without or with BAM15. Combining BAM15 with either semaglutide dose decreased body fat and liver triglycerides, which was not achieved by any monotherapy, while high-dose semaglutide with BAM15 had the greatest effect on glucose homeostasis. This study demonstrates a novel approach to improve weight loss without loss of lean mass and improve glucose control by simultaneously targeting energy intake and energy efficiency. Such a combination may decrease the need for semaglutide dose escalation and hence minimize potential gastrointestinal side effects.

Effectiveness of oral semaglutide on glucose control and body weight up to 18 months: a multicenter retrospective real-world study

AimOral semaglutide, an innovative orally administered GLP-1 receptor agonist for type 2 diabetes (T2D) management was herein evaluated for its effectiveness in a multi-center retrospective real-world study.MethodsWe included new-users of oral semaglutide from 18 specialist care centres and collected retrospective data on baseline clinical characteristics. Updated values of HbA1c and body weight were analyzed using the mixed model for repeated measures.ResultsThe study included 166 individuals with T2D, predominantly men (64.5%), with a mean age of 64.4 years and a mean diabetes duration of 10.1 years. In the majority of patients (68.3%) oral semaglutide was used as a second-line drug, mostly with metformin. At baseline, mean BMI was 28.9 kg/m2 and HbA1c was 7.5%. During the 18-month observation period, oral semaglutide demonstrated significant reductions in HbA1c, with a maximum change of − 0.9%, and 42.1% of patients achieved HbA1c values below 7.0%. Additionally, there was a substantial reduction in body weight, with an estimated change of − 3.4 kg at 18 months, and 30.3% of patients experienced a 5% or greater reduction in baseline body weight. Only 24.2% of patients reached the 14 mg dose. Subgroup analysis revealed that baseline HbA1c > 7%, persistence on drug, not being on a prior therapy with DPP-4 inhibitors, and loosing 5% or more the initial body weight were associated with greater HbA1c reductions.ConclusionThis study supports oral semaglutide as an effective option for T2D treatment, offering improved glucose control and weight management in a real-world setting.

Identification of individuals with diabetes who are eligible for continuous glucose monitoring forecasting

Background and objectivesPredicting glucose levels in individuals with diabetes offers potential improvements in glucose control. However, not all patients exhibit predictable glucose dynamics, which may lead to ineffective treatment strategies. We sought to investigate the efficacy of a 7-day blinded screening test in identifying diabetes patients suitable for glucose forecasting. MethodsParticipants with type 1 diabetes (T1D) were stratified into high and low initial error groups based on screening results (eligible and non-eligible). Long-term glucose predictions (30/60 min lead time) were evaluated among 334 individuals who underwent continuous glucose monitoring (CGM) over a total of 64,460,560 min. ResultsA strong correlation was observed between screening accuracy and long-term mean absolute relative difference (MARD) (0.661–0.736; p < 0.001), suggesting significant predictability between screening and long-term errors. Group analysis revealed a notable reduction in predictions falling within zone D of the Clark Error Grid by a factor of three and in zone C by a factor of two. ConclusionsThe identification of eligible patients for glucose prediction through screening represents a practical and effective strategy. Implementation of this approach could lead to a decrease in adverse glucose predictions.

Is Tirzepatide the New Game Changer in Type 2 Diabetes?

Background: Tirzepatide (TZP) is a once-weekly glucagon-like peptide 1 (GLP-1) and glucose-dependent-insulinotropic-polypeptide (GIP) receptor co-agonist approved for T2D. TZP provides promising evidence in improving glucose control and weight loss in T2D and obesity across preclinical and human studies, including data from the SURPASS program. Aims: The goal of this paper was to review the evidence on TZP in terms of glucose control, body weight, and the progression of chronic diabetes-related complications and comorbidities. Results: The mean change in HbA1c ranged from −1.6% to −2.06% over placebo, from −0.29% to −0.92% over each GLP-1RAs, and from −0.7% to −1.09% over basal insulins. In SURPASS-6, TZP was more effective than insulin lispro U100 added to basal insulin in reducing HbA1c levels at the study end (−2.1% vs. −1.1%, respectively). Compared to placebo, TZP induces a significant weight loss: 7.5 (5 mg/week); 11 (10 mg/week); and 12 kg (15 mg/week). Compared to GLP-1RAs, TZP reduces body weight from −1.68 kg to −7.16 kg depending on the dose (5 to 15 mg, respectively). Compared to basal insulin alone rigorously titrated, TZP added onto basal-insulin results in the best strategy for the composite endpoint of improvement of glucose control and weight loss. In SURPASS-6, TZP compared to insulin lispro U100 in add-on to insulin glargine U100 reduced body weight by 9 kg in mean (versus weight gain in basal-bolus users: +3.2 kg). TZP has pleiotropic effects potentially dampening the individual cardiovascular risk, including a reduction in systolic arterial pressure by 4 to 6 mmHg and total cholesterol by 4–6% compared to baseline. A post hoc analysis of SURPASS-4 revealed that TZP, compared to glargine U100, delayed the rate of glomerular filtration decline (−1.4 mL/min vs. −3.6 mL/min, respectively), reduced the rate of urinary albumin excretion (−6.8% vs. +36.9%, respectively), and was associated with a lower occurrence of the composite renal endpoint (HR 0.58 [0.43; 0.80]). Conclusions: Consistent evidence indicates that TZP dramatically changes the clinical course of T2D in different clinical scenarios. The efficacy and safety of TZP on chronic diabetes-related comorbidities and complications seem promising, but ongoing trials will clarify the real benefits.

Insulin sensitivity and beta cell function after duodenal mucosal resurfacing: an open-label, mechanistic, pilot study

Background and AimsThe duodenum has been shown to play a key role in glucose homeostasis. Duodenal mucosal resurfacing (DMR) is an endoscopic procedure for patients with type 2 diabetes (T2D) in which the duodenal mucosa is hydrothermally ablated. DMR improves glycemic control, but the underlying mechanisms remain unclear. Here, we report changes in glucoregulatory hormones and indices of insulin sensitivity and beta cell function after DMR. MethodsWe included 28 patients on non-insulin glucose lowering medications who underwent open-label DMR and a mixed meal test (MMT) in Revita-1 or Revita-2. Inclusion criteria were hemoglobin A1c (HbA1c) 7.6-10.4% and BMI 24-40kg/m2. Baseline and 3-months MMT data included plasma glucose, insulin, C-peptide, glucagon-like peptide-1 (GLP-1), and gastric inhibitory polypeptide (GIP) concentrations. Glucoregulatory hormones, insulin sensitivity indices (homeostatic model assessment for insulin resistance [HOMA-IR], Matsuda index [MI] and hepatic insulin resistance [HIR]), and beta cell function (insulinogenic index [IGI], disposition index [DI] and insulin secretion rate [ISR]) were assessed. ResultsFasting insulin, glucagon, and C-peptide decreased significantly. Insulin sensitivity (HOMA-IR, MI, and HIR) and beta cell function (DI and ISR) all improved significantly. Decline in postprandial glucose, mainly driven by a decrease in fasting levels, was observed, as well as a decline in postprandial glucagon whereas GLP-1 and GIP did not change. ConclusionsInsulin sensitivity and insulin secretion improved 3 months after DMR. It is unlikely that incretin changes are responsible for improved glucose control after DMR. These data add to the growing evidence validating the duodenum as a therapeutic target for patients with T2D.

Exploring the benefits of cold exposure in health and athletic performance - review of articles

Introduction and purpose: In recent years there has been an increase in scientific research regarding the body's exposure to low temperatures. The potential health benefits have captured the attention of both researchers and the general public. This article review provides an analysis of the existing literature concerning the impact of cold body exposure on health and athletic achievements. Material and methods: A review of the literature available in the "PubMed" database and books was conducted. The search was performed by using the following keywords: "cold exposure", "cryotherapy", "cold shower", "cold-water immersion" and "winter swimming". State of knowledge: Encountering low temperatures can be perceived as a physiological stressor. The body responds to this situation by activating adaptive mechanisms to maintain homeostasis, such as the activation of brown adipose tissue, improved glucose control and increased immune system activity. An increasing amount of data supports the positive impact of cold exposure on athletic performance. Potential benefits are indicated such as enhancing physical endurance through increased heat production and stimulation of the circulatory system, as well as facilitating faster body recovery. Results and Conclusions: The article review indicates a growing interest in the impact of cold exposure. While there are encouraging findings of positive effects, further research is necessary for better understanding and determining the optimal conditions for achieving maximum benefits. This information could have a significant impact on the development of training strategies and health prevention.

Exploring the molecular mechanisms of macrophages in islet transplantation using single-cell analysis.

Islet transplantation is a promising treatment for type 1 diabetes that aims to restore insulin production and improve glucose control, but long-term graft survival remains a challenge due to immune rejection. ScRNA-seq data from syngeneic and allogeneic islet transplantation grafts were obtained from GSE198865. Seurat was used for filtering and clustering, and UMAP was used for dimension reduction. Differentially expressed genes were analyzed between syngeneic and allogeneic islet transplantation grafts. Gene set variation analysis (GSVA) was performed on the HALLMARK gene sets from MSigDB. Monocle 2 was used to reconstruct differentiation trajectories, and cytokine signature enrichment analysis was used to compare cytokine responses between syngeneic and allogeneic grafts. Three distinct macrophage clusters (Mø-C1, Mø-C2, and Mø-C3) were identified, revealing complex interactions and regulatory mechanisms within macrophage populations. The significant activation of macrophages in allogeneic transplants was marked by the upregulation of allograft rejection-related genes and pathways involved in inflammatory and interferon responses. GSVA revealed eight pathways significantly upregulated in the Mø-C2 cluster. Trajectory analysis revealed that Mø-C3 serves as a common progenitor, branching into Mø-C1 and Mø-C2. Cytokine signature enrichment analysis revealed significant differences in cytokine responses, highlighting the distinct immunological environments created by syngeneic and allogeneic grafts. This study significantly advances the understanding of macrophage roles within the context of islet transplantation by revealing the interactions between immune pathways and cellular fate processes. The findings highlight potential therapeutic targets for enhancing graft survival and function, emphasizing the importance of understanding the immunological aspects of transplant acceptance and longevity.

Semaglutide-associated hyposalivation: A report of case series

Rationale: Obesity and diabetes of different types are considered global health risks with rising prevalence. In addition to low-calorie diet and daily exercise, several treatment options have been introduced to help patient in needs. Semaglutide (Ozempic) is one popular agent, which attracted the attention of both physicians and patients due to its positive outcome in improving glucose control and weight loss. However, no reports on the effect of semaglutide use on the oral cavity and specifically xerostomia are available in the literature. We are reporting 3 cases for patients who were using semaglutide and developed secondary xerostomia. Patient concerns: Three female patients with median age of 34 (range 27–46) presented to the oral medicine clinic with chief complaint of xerostomia. All patients were overweight with a mean body mass index of 35.6 (range 35–37) and have been using semaglutide for weight loss for a mean duration of 11.3 weeks (range 6–16). Diagnoses: All 3 patients had severe dryness in the mouth with minimal frothy saliva with mean modified Schirmer test of 9 mL at 3 minutes (range 8–10 mL). Following exclusion of other possible underlying medical problems, the diagnosis of semaglutide-induced hyposalivation was given to all patients. Interventions: The patients’ management varied between discontinuation of the drug, the use of pilocarpine, and conservative symptomatic management. Outcomes: The patients resumed acceptable salivary flow. Lessons: We are reporting for the first time hyposalivation associated with the use of semaglutide. Further prospective, larger studies are warranted to confirm these findings.

Adrenalectomy Improves Body Weight, Glucose, and Blood Pressure Control in Patients With Mild Autonomous Cortisol Secretion: Results of an Randomized Controlled Trial by the Co-work of Adrenal Research (COAR) Study.

To assess the metabolic effects of adrenalectomy in patients with mild autonomous cortisol secretion (MACS). Despite retrospective studies showing the association of adrenalectomy for MACS with beneficial metabolic effects, there have been only 2 randomized prospective studies with some limitations to date. A prospective, multicenter study randomized 132 patients with adrenal incidentaloma without any features of Cushing syndrome but with serum cortisol >50 nmol/L after a 1 mg overnight dexamethasone suppression test into an adrenalectomy group (n = 66) or control group (n = 66). The primary outcomes were changes in body weight, glucose, and blood pressure (BP). Among the 118 participants who completed the study with a median follow-up duration of 48 months (range: 3-66), the adrenalectomy group (n = 46) exhibited a significantly higher frequency of improved weight control, glucose control, and BP control (32.6%, 45.7%, and 45.7%, respectively) compared with the control group (n = 46; 6.5%, P = 0.002; 15.2%, P = 0.002; and 23.9%, P = 0.029, respectively) after matching for age and sex. Adrenalectomy [odds ratio (OR) = 10.38, 95% CI = 2.09-51.52, P = 0.004], body mass index (OR = 1.39, 95% CI = 1.08-1.79, P = 0.010), and cortisol after a 1 mg overnight dexamethasone suppression test levels (OR = 92.21, 95% CI = 5.30-1604.07, P = 0.002) were identified as independent factors associated with improved weight control. Adrenalectomy (OR = 5.30, 95% CI = 1.63-17.25, P = 0.006) and diabetes (OR = 8.05, 95% CI = 2.34-27.65, P = 0.001) were independently associated with improved glucose control. Adrenalectomy (OR = 2.27, 95% CI = 0.87-5.94, P = 0.095) and hypertension (OR = 10.77, 95% CI = 3.65-31.81, P < 0.001) demonstrated associations with improved BP control. adrenalectomy improved weight, glucose, and BP control in patients with MACS.

Effectiveness of Nurse-led Educational Interventions on Glycemic Control and Self-care Behaviors of Type 2 Diabetics: A Systematic Review

Background: Blood glucose control is challenging for patients with diabetes and is often associated with self-care behaviors. The effectiveness of nurse-led educational interventions for glycemic control and self-care behaviors in patients with type 2 diabetes is unclear.Objective: To determine effectiveness of nurse-led educational intervention on glycemic control and self-care behaviors in patients with type 2 diabetes.Design: Mixed methods systematic review.Data Sources: A comprehensive search in Medline, CINAHL and Scopus was conducted in February 2023 to identify peer-reviewed papers published between 2003 and 2023.Review Methods: The review was guided by the Joanna Briggs Institute systematic review manual. Data were extracted and assessed by two evaluators using a standardized checklist. Due to the high level of heterogeneity between studies, the data were analyzed using Popay et al.'s (2006) conduct of narrative synthesis in systematic reviews.Results: Ten randomized controlled trials met the inclusion criteria. Studies described nurse-led educational interventions delivered either face-to-face or online. The outcomes of the educational interventions and the measurement tools used were diverse, with many studies reporting attrition. Most studies reported that nurse-led educational interventions improved outcomes for patients with type 2 diabetes.Conclusions: The evidence identifies that nurse-led educational interventions are effective for glycemic control and self-care behaviors in patients with type 2 diabetes. This review demonstrates evidence of approaches that could inform future practice and research to support all adult populations of patients with type 2 diabetes to improve glucose control and self-care behaviors. Future research would benefit from well-designed clinical trials that use common outcome measures to provide more information about the effectiveness as well as the sustainability of such interventions.

Advanced decision support system for individuals with diabetes on multiple daily injections therapy using reinforcement learning and nearest-neighbors: In-silico and clinical results

Many individuals with diabetes on multiple daily insulin injections therapy use carbohydrate ratios (CRs) and correction factors (CFs) to determine mealtime and correction insulin boluses. The CRs and CFs vary over time due to physiological changes in individuals' response to insulin. Errors in insulin dosing can lead to life-threatening abnormal glucose levels, increasing the risk of retinopathy, neuropathy, and nephropathy. Here, we present a novel learning algorithm that uses Q-learning to track optimal CRs and uses nearest-neighbors based Q-learning to track optimal CFs. The learning algorithm was compared with the run-to-run algorithm A and the run-to-run algorithm B, both proposed in the literature, over an 8-week period using a validated simulator with a realistic scenario created with suboptimal CRs and CFs values, carbohydrate counting errors, and random meals sizes at random ingestion times. From Week 1 to Week 8, the learning algorithm increased the percentage of time spent in target glucose range (4.0 to 10.0 mmol/L) from 51 % to 64 % compared to 61 % and 58 % with the run-to-run algorithm A and the run-to-run algorithm B, respectively. The learning algorithm decreased the percentage of time spent below 4.0 mmol/L from 9 % to 1.9 % compared to 3.4 % and 2.3 % with the run-to-run algorithm A and the run-to-run algorithm B, respectively. The algorithm was also assessed by comparing its recommendations with (i) the endocrinologist's recommendations on two type 1 diabetes individuals over a 16-week period and (ii) real-world individuals' therapy settings changes of 23 individuals (19 type 2 and 4 type 1) over an 8-week period using the commercial Bigfoot Unity Diabetes Management System. The full agreements (i) were 89 % and 76 % for CRs and CFs for the type 1 diabetes individuals and (ii) was 62 % for mealtime doses for the individuals on the commercial Bigfoot system. Therefore, the proposed algorithm has the potential to improve glucose control in individuals with type 1 and type 2 diabetes.

The effect of thiazolidinediones on body fat redistribution in adults: A systematic review and meta-analysis of randomized controlled trials.

Visceral adiposity is a strong predictor of cardiometabolic risk. Thiazolidinediones (TZDs) are associated with a shift in fat redistribution from visceral adipose tissue (VAT) to subcutaneous adipose tissue (SAT). We aimed to compare the effects of TZD and other interventions on fat remodeling in adults in randomized controlled trials. Among the 1331 retrieved studies, 39 trials with 1765 participants were included in the meta-analysis. The standardized mean difference in VAT change was not significantly different between TZD and comparators across the overall studies. Intriguingly, TZD treatment resulted in significant decreases in VAT compared with placebo and sulfonylureas (p < 0.05), although recombinant human growth hormone was superior to TZD regarding VAT reduction (p < 0.05). Data from 216 participants showed TZD leading to a greater reduction in liver fat percentage than comparators (p < 0.05). Compared with the controls, TZD significantly increased SAT, total body fat, weight, waist circumference, and body mass index (p < 0.05). However, TZD pronouncedly improved glucose control, insulin resistance, adiponectin, and lipid profile (p < 0.05). TZD provides a favorable effect on fat redistribution and benefits insulin sensitivity, suggesting a potentially valuable approach in cardiometabolic risk management.

Calisthenics versus Pilates training on glycemic control and body fat in overweight individuals with type 2 diabetes mellitus

BACKGROUND: Physical activity plays an important role in management and preventing complications of type 2 diabetes mellitus (DM). Effectiveness of Pilates on DM showed that there was improvement in glucose control. Presently, resistance training forms are becoming very popular for weight loss and DM. Calisthenics is a relatively new form of resistance exercise training that has been less studied in obese and diabetic individuals. STUDY PURPOSE: To evaluate and compare the effect of Calisthenics and Pilates training approaches on percentage body fat and glycemic control (HbA1C, Post Prandial Blood Glucose (PPBG)) in overweight individuals with type 2 Diabetes mellitus (DM). METHODS: Thirty (n = 30) over weight individuals with type 2 DM with HbA1C levels &gt;6.5% were recruited for the study. The participants were randomly allocated to calisthenics (CG) and Pilates (PG) study groups who received respective exercise interventions for 12 weeks. The outcome measures were HbA1C, PPBG and percentage body fat assessed at pre and post intervention. RESULTS: Both CG and PG study groups showed statistically significant difference for glycemic control (HbA1C, PPBG) post 12 week intervention. However, significant improvement was noted in CG than PG in terms of HbA1c (p = 0.03), PPBG (P = 0.01) and body fat percentage (p &lt; 0.0001). CONCLUSION: Calisthenics exercise training was more effective than the Pilates training in achieving long term (HbA1c) and post meal (PPBS) glycemic control with significant reduction in body fat percentage in overweight individuals with type 2 DM.

HAMSAB diet ameliorates dysfunctional signaling in pancreatic islets in autoimmune diabetes

An altered gut microbiota is associated with type 1 diabetes (T1D), affecting the production of short-chain fatty acids (SCFA) and glucose homeostasis. We previously demonstrated that enhancing serum acetate and butyrate using a dietary supplement (HAMSAB) improved glycemia in non-obese diabetic (NOD) mice and patients with established T1D. The effects of SCFA on immune-infiltrated islet cells remain to be clarified. Here, we performed single-cell RNA sequencing on islet cells from NOD mice fed an HAMSAB or control diet. HAMSAB induced a regulatory gene expression profile in pancreas-infiltrated immune cells. Moreover, HAMSAB maintained the expression of β-cell functional genes and decreased cellular stress. HAMSAB-fed mice showed preserved pancreatic endocrine cell identity, evaluated by decreased numbers of poly-hormonal cells. Finally, SCFA increased insulin levels in human β-like cells and improved transplantation outcome in NOD/SCID mice. Our findings support the use of metabolite-based diet as attractive approach to improve glucose control in T1D.

OXM-104, a potential candidate for the treatment of obesity, NASH and type 2 diabetes

ObjectiveDual glucagon-like peptide-1 (GLP-1) and glucagon receptor agonists are therapeutic agents with an interesting liver-specific mode of action suitable for metabolic complications. In this study, dual GLP-1 and glucagon receptor agonist OXM-104 is compared head-to-head with the once-daily dual GLP-1 and glucagon receptor agonist cotadutide and GLP-1 receptor agonist semaglutide to explore the metabolic efficacy of OXM-104. MethodsThe in vitro potencies of OXM-104, cotadutide and semaglutide were assessed using reporter assays. In addition, in vivo efficacy was investigated using mouse models of diet-induced obesity (DIO mice), diabetes (db/db mice) and diet-induced NASH mice (MS-NASH). ResultsOXM-104 was found to only activate the GLP-1 and glucagon with no cross-reactivity at the (GIP) receptor. Cotadutide was also found to activate the GLP-1 and glucagon receptors, whereas semaglutide only showed activity at the GLP-1 receptor. OXM-104, cotadutide, and semaglutide elicited marked reductions in body weight and improved glucose control. In contrast, hepatoprotective effects, i.e., reductions in steatosis and fibrosis, as well as liver fibrotic biomarkers, were more prominent with OXM-104 and cotadutide than those seen with semaglutide, demonstrated by an improved NAFLD activity score (NAS) by OXM-104 and cotadutide, underlining the importance of the glucagon receptor. ConclusionThese results show that dual GLP-1 and glucagon receptor agonism is superior to GLP-1 alone. OXM-104 was found to be a promising therapeutic candidate for the treatment of metabolic complications such as obesity, type 2 diabetes and NASH.

Effectiveness of Continuous Glucose Monitoring on Metrics of Glycemic Control in Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

To provide a systematic review and meta-analysis synthesizing the findings of randomized controlled trials (RCTs) of continuous glucose monitors (CGMs) in the management of adults with type 2 diabetes mellitus (T2DM) on glucose control and clinical outcomes. MEDLINE, Embase, and Cochrane were searched for RCTs that assessed the effectiveness of real-time CGM (rt-CGM) or flash CGM (FGM) in adults (≥18 years) with T2DM that reported on at least 1 of the following outcomes: hemoglobin A1c (HbA1c), time in range, time in hyperglycemia, or time in hypoglycemia. The GRADE approach was used to assess certainty of evidence for primary outcomes. Fourteen RCTs assessing CGM were included, with 825 patients in 9 RCTs using rt-CGM and 822 in 5 RCTs using FGM. Moderate certainty of evidence indicated that use of CGM had a modest but statistically significant reduction in HbA1c levels of about 0.32%. Our analyses of each device type separately showed similar reductions in HbA1c (0.34% and 0.33%, respectively, for rt-CGM and FGM), with trends for improvement in other glucose metrics favoring rt-CGM over self-monitored blood glucose. Both rt-CGM and flash CGM led to modest but statistically significant declines in HbA1c among individuals with T2DM, with little heterogeneity in the results. However, the duration of the included RCTs was relatively short and few studies reported on important clinical outcomes, such as adverse events, emergency department use, or hospitalization. Longer term studies are needed to determine if the short-term improvements in glucose control leads to improvements in clinically important outcomes.

Effects of high intensity training on glycated hemoglobin type A1C reduction and insulin resistance changes compared to moderate intensity training in patients with type 2 diabetes : a systematic review and meta analysis

Background: In most of the type 2 Diabetes management recommends lifestyle including physical activity. Several studies have examined the effects of HIT and MIT on the glycated Hemoglobin type A1C (HbA1c) and Insulin resistance reduction in type 2 Diabetes. Objective: The objective of this meta-analysis was to investigate the impacts of high and moderate intensity training to reducing HbA1C and changes insulin resistance in type 2 Diabetes Melitus patient.State the objectives of the research. Material and Method: We searched the online databases of PubMed, ScienceDirect, and Cochrane Library for relevant studies evaluating the effects of High Intensity Training on T2DM patients. Using random effects model, comparing Mean Difference and standard deviation with 95% confidence internal (CI) were used to investigate the studies.Conclusion: In this study we found that HIT showed significantly better result to reduced HbA1C. HIT improves glucose control center’s ability to recruit more muscle fibers and depleting muscle glycogen levels compared to MIT, HIT does not significantly reduce insulin resistance compared to MIT.
