Abstract
Diabetes mellitus, particularly type II diabetes mellitus, is a metabolic condition that has a substantial impact on the health of individuals. The implication of diabetes with increased risk of cardiovascular diseases (CVD) and, consequently, myocardial infarction is well established. However, developing new antidiabetic drugs with an established efficacy on cardiovascular health is an underdeveloped area of research. To address this, in the present study, a new series of chromene-3-carboxylate derivatives (1B1-1B22) as dual inhibitors of Angiotensin II Type 1 Receptor (AT1R) and Neprilysin (NEP), which are recognized targets in diabetes with CVD, is reported. The compounds were rationally designed and synthesized, considering the pharmacophoric features of these two targets. The evaluation was performed via glucose uptake, α-amylase, AT1R, and NEP inhibition assay. The derivatives were found to increase glucose uptake and inhibit all three targets, of which compound 1B15 was the most active. The most active compound, 1B15, reduced the oxidative stress and restored the mitochondrial membrane potential. The biological findings were further corroborated by in silico studies, which included molecular modelling and dynamics. It was deduced that 1B15 remains unionized in acidic to weak basic pH and may be passively absorbed. Further, the molecule was found to undergo hydroxylation as a means of Phase I metabolism and glucuronic conjugation in Phase II. The wet lab experiments on 1B15 further validated the in-silico absorption and metabolism prediction. The compounds, particularly 1B15, could be explored further as a lead for its utility as an antidiabetic with profound implications on cardiovascular health.

Early weight loss, diabetes remission and long-term trajectory after diagnosis of type 2 diabetes: a retrospective study. Diabetologia 2025; 68:1115-1125. [PMID: 40119903 PMCID: PMC12069414 DOI: 10.1007/s00125-025-06402-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2024] [Accepted: 02/06/2025] [Indexed: 03/25/2025]
Abstract
AIMS/HYPOTHESIS Weight loss can improve glycaemic management in individuals with type 2 diabetes, but its long-term effects on remission, cardiovascular risk factors and complications remain unclear. We investigated clinical outcomes following non-interventional ≥10% body weight loss in people with newly diagnosed type 2 diabetes in a routine care setting. METHODS We retrospectively analysed two cohorts of people with newly diagnosed type 2 diabetes. After exclusions, cohort 1 included 1934 individuals followed for up to 25 years; cohort 2 comprised 13,277 individuals followed for up to 10 years. Participants were categorised into two groups based on whether or not they lost at least 10% body weight. In a sensitivity analysis, a group of participants with intermediate weight loss (5% to <10%) was also considered. Outcomes included HbA1c, diabetes remission, cardiovascular parameters and chronic complications. RESULTS Participants (58% male) had a mean age of 62 years and a mean diabetes duration of <2 years at inclusion; mean baseline HbA1c was 57-64 mmol/mol (7.4-8.0%) and mean BMI was ~30 kg/m2. Weight loss ≥10% was obtained in 15.9% (n=308) of participants in cohort 1 and in 8.8% (n=1167) in cohort 2. In cohort 1, weight loss ≥10% was associated with a sustained reduction in HbA1c (mean difference 2.1 mmol/mol; 0.19%) and a higher remission rate than in the <10% weight loss group (20.2% vs 5.5%; HR 4.2). These findings were confirmed in cohort 2, with remission rates of 13.2% and 4.1% (HR 2.6) in the ≥10% and <10% weight loss groups, respectively. Weight loss ≥10% improved systolic BP and HDL-cholesterol and triglyceride levels. Participants with weight loss of 5% to <10% (28.2% in cohort 1 and 17.4% in cohort 2) had marginal improvements in HbA1c, lipids and remission rates compared with participants with weight loss <5%, and such results were inferior to those achieved with weight loss ≥10%. In cohort 1, compared with weight loss <5% (reference), the HR for remission was 5.2 with weight loss ≥10% vs 1.7 with weight loss 5% to <10%. Weight loss ≥10% was not associated with a reduced incidence of complications. On the other hand, remission was independently associated with a significantly lower rate of new-onset microangiopathy (adjusted HR 0.84; 95% CI 0.73, 0.97; p=0.019). CONCLUSIONS/INTERPRETATION Early weight loss of ≥10% in type 2 diabetes was associated with sustained glycaemic improvements, increasing by three to four times the rates of diabetes remission. Remission, in turn, more than weight loss was associated with a reduced risk of complications.

Abstract
INTRODUCTION Medication management after bariatric surgery is a major and complex challenge. The altered gastrointestinal anatomy/physiology post-surgery may impact oral drug absorption/pharmacokinetics, with potential clinical implications. Along with multiple studies/cases of impaired post-surgery drug absorption/pharmacokinetics, leading to potential treatment failure, reports of increased drug exposure, leading to post-bariatric safety issues and adverse effects risk, are also available; yet, this second scenario of increased post-surgery drug levels, is less familiar in practice. AREAS COVERED In this article, we highlight and overview the literature reports of increased post-bariatric drug exposure and safety issues, and discuss the underlying relevant mechanisms. Finally, we provide clinical recommendations for managing this therapeutic challenge. EXPERT OPINION Around 25 drugs were found to exhibit post-bariatric enhanced pharmacokinetics and risk of adverse effects. Among them, toxicity with lithium treatment is well-established. Clear safety concerns were also raised for other drugs, including levothyroxine, atorvastatin, paracetamol and, importantly, immediate-release morphine. Cautious use, while closely monitoring clinical signs of toxicity, is advised for these drugs. Realizing the potentially altered post-bariatric pharmacokinetics of various drugs, and, in particular, the risk of increased exposure with related adverse effects, is essential for providing optimal pharmacological therapy and overall patient care to the growing bariatric population.

Abstract
BACKGROUND Previous studies demonstrated that diabetes remission can occur during intensive intervention and in real-world settings. However, the impact of diabetes remission in real-world settings on the incidence of cardiovascular disease (CVD) remains unclear. METHODS This retrospective cohort study included 299,967 individuals aged 20-72 years who underwent multiple checkups between 2008 and 2020 and completed ≥ 3 years of follow-up. Patients were divided into four groups according to changes in glycated hemoglobin levels and the use of diabetes medications during the 1-year baseline period: diabetes mellitus (DM)+/no remission, DM+/remission, DM-/no progression, and DM-/progression. The risk of CVD was evaluated using multivariable Cox regression analysis. RESULTS The median follow-up period was 5.0 years. The rates of CVD in the DM+/no remission, DM+/remission, DM-/no progression, and DM-/progression groups were 7.96, 4.76, 1.99, and 5.47 per 1000 person-years, respectively. Compared with DM+/no remission, DM+/remission reduced the risk of CVD [hazard ratio (HR) = 0.71, 95% confidence interval (CI) = 0.57-0.89]. Meanwhile, the HR for CVD in the DM+/remission group was 0.75 (95% CI = 0.56-0.99) for change in BMI ≤ 0%, versus 0.66 (95% CI = 0.45-0.96) for change in BMI > 0%. CONCLUSIONS In a real-world setting without intensive intervention, diabetes remission decreased the risk of CVD by approximately 30% regardless of changes in BMI, suggesting that diabetes remission can prevent CVD without weight loss in routine care and emphasizing the importance of achieving remission.

Abstract
We report a case of new-onset, nonautoimmune, nonketotic, and noninsulinopenic type 2-like diabetes in a previously normoglycemic middle-aged man debuting after vaccination against COVID-19. This was not a mild or short-lived glucose intolerance, but severe and long-standing hyperglycemia with a high glycated hemoglobin level. However, the course of the diabetes was highly atypical and surprising in that it spontaneously disappeared after a few months and did not recur despite the patient being off all antidiabetic drugs for several months and without any changes in body weight or lifestyle. The mechanisms by which severe diabetes unfolded and later remitted in this patient remain elusive. Nonetheless, and notwithstanding whether or not there was a cause-and-effect relation between the vaccinations and his diabetes, the highly atypical course of spontaneously remitting nonautoimmune diabetes lends itself to mechanistic efforts aimed at understanding the biology and pathophysiology of insulin-producing β cells in health and disease. This case report should not be construed as vaccine skepticism or deter anyone, especially with diabetes/obesity, from vaccination against COVID-19. However, it calls for increased vigilance among health care providers for unusual and unexpected metabolic effects of COVID-19 and its vaccines.

Abstract
Obesity is an important health concern that poses many public health challenges. Evidence-based treatment modalities, capable of cost-effectively reaching large patient groups are needed. In this paper, we present the design and methods of the updated national, 12-month, digital weight management program, the Healthy Weight Coaching (HWC). The major updates, as compared to the previous version, are related to the theoretical background of the obesity management and updated BMI cut-offs. The HWC is available, based on physicians' referrals, to adult Finnish citizens with BMI ≥30 kg/m2 or ≥27 kg/m2 with a comorbidity, who have a health-based need to lose weight. Rooted in the principles of behavioural therapy, the HWC focuses on teaching coping skills, guides to healthy self-reflection, and supports concrete lifestyle changes as part of healthy weight loss. The automated weekly training sessions, supplemented by 3-8 exercises, form the basis of the program. These sessions address topics such as diet, physical activity, stress management, and rest and recovery. Additionally, a personal coach is allocated to each patient to provide tailored support. At baseline, patients record their weight, height, and waist circumference, online, and complete questionnaires on lifestyle, diet, physical activity, sleep, psychological factors, and health. Thereafter weight recording is conducted at least every 4 weeks, while the questionnaires and measuring the weight circumference are repeated at 3, 6, 9, and 12 months. In addition, patients can make use of diaries and peer group chats for additional support. Data collected from the consenting patients will be used for research purposes with the weight change from baseline to 12 months as the main outcome in the real-life observational study. The study will provide invaluable insights into the application of digital modalities in the treatment of obesity.

Abstract
Common psychiatric disorders (CPDs) and depression contribute significantly to the global epidemic of type 2 diabetes (T2D). We postulated a possible pathophysiological mechanism that through Bridge-Symptoms present in depression and CPDs, promotes the establishment of emotional eating, activation of the reward system, onset of overweight and obesity and, ultimately the increased risk of developing T2D. The plausibility of the proposed pathophysiological mechanism is supported by the mechanism of action of drugs such as naltrexone-bupropion currently approved for the treatment of both obesity/overweight with T2D and as separate active pharmaceutical ingredients in drug addiction, but also from initial evidence that is emerging regarding glucagon-like peptide 1 receptor agonists that appear to be effective in the treatment of drug addiction. We hope that our hypothesis may be useful in interpreting the higher prevalence of CPDs and depression in patients with T2D compared with the general population and may help refine the integrated psychiatric-diabetic therapy approach to improve the treatment and or remission of T2D.
