AbstractAbstract PDF
Type 2 diabetes mellitus (T2DM) is increasingly recognized as a heterogeneous, multisystem disease that extends beyond chronic hyperglycemia to encompass cardiovascular disease, chronic kidney disease, and metabolic dysfunction-associated steatotic liver disease. Central to this expanded disease spectrum is insulin resistance arising from coordinated metabolic, inflammatory, neuroendocrine, and immune disturbances across multiple organs. Rather than a uniform defect in insulin signaling, insulin resistance represents a dynamic, tissue-specific, and stage-dependent process involving multiorgans, with substantial interorgan crosstalk. This review synthesizes contemporary mechanistic insights into the pathogenesis of insulin resistance in T2DM, integrating molecular pathways, organ-specific dysfunction, and systemic metabolic networks. Ectopic lipid accumulation, mitochondrial dysfunction, chronic low-grade inflammation, immune dysregulation, and gut dysbiosis are highlighted as convergent processes that impair insulin action and drive clinical heterogeneity. Insulin resistance is further contextualized within the cardiovascular–kidney–metabolic syndrome framework, which unifies metabolic, renal, and cardiovascular disease through shared upstream mechanisms. In addition, how contemporary glucose-lowering therapies exert benefits beyond glycemic control by targeting insulin resistance, metabolic reprogramming, and interorgan crosstalk is discussed. Collectively, insulin resistance is positioned as a central pathophysiological driver of T2DM and its complications, supporting a shift toward mechanism-based, organ-protective, and precision-oriented therapeutic strategies.

AbstractAbstract PDF
Finerenone reduces kidney and cardiovascular risk in patients with type 2 diabetes mellitus (T2DM) and albuminuric chronic kidney disease (CKD). Recent Asian subgroup, pooled, combination-therapy, Asian versus non-Asian, and real-world analyses have expanded the evidence base relevant to Asian practice. These data support the consistency of finerenone efficacy and safety in Asian patients and do not support withholding treatment on the basis of Asian ethnicity alone. However, the central question in Asia is shifting from whether finerenone is effective to how eligible patients can be identified, treated, monitored, and continued on therapy in routine care. This review summarizes Asian evidence from the FIDELIO-DKD, FIGARO-DKD, FIDELITY, and CONFIDENCE programs and emerging Asian real-world data. Focus is placed on persistent albuminuric risk, potassium monitoring, treatment sequencing with sodium-glucose cotransporter 2 inhibitors, and implementation feasibility across heterogeneous health-care systems. Finerenone should be considered an evidence-based add-on therapy when baseline potassium and kidney function are appropriate and early laboratory monitoring can be delivered. Simultaneous or early combination therapy may be appropriate in selected high-risk patients, but is not a universal default strategy. The practical priority is to strengthen CKD phenotyping, albuminuria testing, structured potassium monitoring, and care pathways that support sustained use of trial-proven therapy.

Background
To investigate the association between cardiorespiratory fitness (CRF) and the risk of incident microvascular complications in patients with type 2 diabetes mellitus (T2DM), and to assess the effect of genetic risk and potential mediation by circulating biomarkers.
Methods
This prospective analysis included 3,102 adults with T2DM from the UK Biobank. CRF was estimated as maximal oxygen uptake using a submaximal cycle test and categorized as low, moderate, or high. Cox proportional hazards models were used to estimate hazard ratios (HRs) for incident diabetic nephropathy, retinopathy, and neuropathy. Interactions with a polygenic risk score and mediating roles of biomarkers were evaluated.
Results
Over a median 12.47-year follow-up, 331 nephropathy, 268 retinopathy, and 88 neuropathy cases were recorded. Compared to low CRF, moderate and high CRF were associated with 22% (HR, 0.78; 95% confidence interval [CI], 0.61 to 0.99) and 45% (HR, 0.55; 95% CI, 0.36 to 0.85) lower risks of nephropathy, respectively. Each 1-metabolic equivalent of task increment in CRF was linked to 11% lower nephropathy risk. No significant associations were found for retinopathy or neuropathy. Genetic predisposition did not modify the association between CRF and diabetic nephropathy. Triglycerides and white blood cell count accounted for 7.46% and 12.88% of the association, respectively.
Conclusion
Higher CRF is independently associated with lower risk of diabetic nephropathy in T2DM, and genetic risk does not alter this relationship. The association was partially mediated by triglycerides and white blood cell count. Assessing CRF may improve risk stratification and prevention of diabetic kidney disease.

Background
Oxidized lipoproteins contribute to atherosclerosis and metabolic dysfunction; however, their prognostic significance for major adverse cardiovascular events (MACEs) in patients with type 2 diabetes mellitus (T2DM) and coexisting coronary heart disease (CHD) remains unclear.
Methods
This multicenter cohort included 3,733 patients with angiographically confirmed T2DM-CHD, followed for 5 years. Baseline circulating oxidized high-density lipoprotein cholesterol (ox-HDL-C), oxidized low-density lipoprotein cholesterol (ox- LDL-C), and oxidized lipoprotein(a) (ox-Lp(a)) were measured, and associations with coronary severity, β-cell function, and MACEs were analyzed using Cox regression, Kaplan-Meier, and restricted cubic spline models.
Results
Patients with MACEs had higher baseline ox-HDL-C, ox-LDL-C, and ox-Lp(a), correlating with greater coronary lesion burden and impaired β-cell function. Restricted cubic spline analyses revealed nonlinear, dose-dependent associations, with MACEs risk increasing above thresholds of 19.88 ng/mL (ox-HDL-C), 25.71 ng/mL (ox-LDL-C), and 19.96 μmol/L (ox-Lp(a)), with sexspecific differences observed. In Cox proportional hazards models, individuals in the highest quartile of oxidized lipoproteins had significantly elevated 5-year MACEs risk compared to those in the lowest quartile, and these associations remained robust after adjusting for confounders (ox-HDL-C: adjust hazard ratio [HR], 1.872; 95% confidence interval [CI], 1.408 to 2.489; P<0.001; ox- LDL-C: adjust HR, 2.239; 95% CI, 1.686 to 2.974; P<0.001; ox-Lp(a): adjust HR, 1.917; 95% CI, 1.442 to 2.549; P<0.001).
Conclusion
Oxidized lipoproteins are independent predictors of MACEs in patients with T2DM-CHD and reflect vascular and metabolic dysfunction. Incorporating oxidized lipoprotein profiling into clinical risk assessment may improve early identification of high-risk individuals and guide preventive strategies.

AbstractAbstract PDFPubReader   ePub   
Diabetic microvascular complications, including nephropathy, retinopathy, and neuropathy, are major causes of morbidity in diabetes. Increasing evidence highlights neutrophils as key contributors to the chronic inflammatory processes underlying these complications. In the diabetic environment, neutrophils exhibit impaired recruitment, defective phagocytosis, dysregulated degranulation, and excessive production of reactive oxygen species and neutrophil extracellular traps (NETs). These dysfunctions not only reduce pathogen clearance but also exacerbate tissue injury through persistent low-grade inflammation. Furthermore, neutrophils interact with other immune cells, such as macrophages, dendritic cells, T cells, and B cells, perpetuating immune imbalance and tissue damage. Various neutrophil-derived cytokines and granular proteins also influence vascular permeability and endothelial dysfunction. In recent years, neutrophil-related biomarkers—such as absolute neutrophil count, neutrophil-to-lymphocyte ratio, platelet-to-neutrophil ratio, and systemic immune-inflammation index—have gained attention as accessible and cost-effective tools for predicting and monitoring diabetic microvascular complications. This review summarizes the multifaceted roles of neutrophils in the pathogenesis of diabetic microvascular disease and highlights emerging clinical applications of neutrophil-based inflammatory biomarkers. A better understanding of neutrophil-driven mechanisms may open new avenues for early diagnosis, therapeutic intervention, and personalized care in diabetic patients.

Background
Adipose tissue consists predominantly of lipid-filled adipocytes with limited cytoplasmic space, posing challenges for spatial transcriptomic analysis. Spatially-resolved laser-activated cell sorting (SLACS) enables precise isolation of tissue sections, offering a strategy to overcome these challenges.
Methods
Human visceral adipose tissue (VAT) samples from lean individuals and those with obesity and type 2 diabetes mellitus (Ob-DM) were analyzed. SLACS was used to isolate perivascular (PV) and adipocyte-rich (AD) areas, followed by full-length RNA sequencing to investigate pathways, cellular composition, and post-transcriptional regulation.
Results
PV and AD areas exhibited distinct transcriptional patterns. Fibro-inflammatory signatures and vascular remodeling pathways were enriched in the PV, while lipid metabolism and antioxidant pathways were predominant in the AD. Cellular deconvolution suggested area- and disease-specific cell composition. Post-transcriptional modifications, including adenosine-to-inosine (A-to-I) RNA editing and isoform switching in metabolic genes were observed in Ob-DM, suggesting a potential contributor to adipose dysfunction.
Conclusion
This study demonstrates the technical feasibility of SLACS-based spatial transcriptomic profiling in human VAT, with exploratory biological findings that warrant validation in larger cohorts.

Background
Evidence supporting the benefits of continuous glucose monitoring (CGM) in reducing diabetes-related complications remains scarce. This study aimed to investigate the association between CGM and diabetes-related complications, specifically diabetic ketoacidosis (DKA) and severe hypoglycemia in children and adolescents with type 1 diabetes mellitus (T1DM).
Methods
From the Korean Nationwide Cohort (2016–2022), we included children and adolescents (aged <19 years) with T1DM who received rapid-acting insulin between 2019 and 2022. The primary outcomes were DKA and severe hypoglycemia. Adjusted hazard ratios (HRs) for the primary outcomes were compared between CGM users and non-users using Cox proportional hazards regression models. Additionally, among the CGM users, the frequencies of DKA and severe hypoglycemia were compared before and after CGM initiation using a paired t-test.
Results
This study included 3,765 children and adolescents (2,313 CGM users and 1,452 non-users). During a median follow-up of 2.7 years, CGM users showed a lower risk of DKA (adjusted HR, 0.44; 95% confidence interval [CI], 0.35 to 0.56) and severe hypoglycemia (adjusted HR, 0.48; 95% CI, 0.29 to 0.79) than non-users. Among CGM users, the mean frequency of DKA decreased by 64%, and that of severe hypoglycemia decreased by 57% after CGM initiation (P<0.001 for both).
Conclusion
In this nationwide cohort study, CGM was associated with a reduced risk of DKA and severe hypoglycemia in children and adolescents with T1DM.

Background
High 1-hour plasma glucose (1-h PG) level has been proposed by the International Diabetes Federation to identify high-risk individuals and diagnose type 2 diabetes mellitus (T2DM). In a longitudinal cohort, we examined T2DM risk, β-cell function, and the genetic and lifestyle effects associated with the high 1-h PG.
Methods
We analyzed 6,588 participants without baseline T2DM from a community-based prospective cohort in Korea. Participants underwent biennial 2-hour 75-g oral glucose tolerance tests over 14 years. We assessed incident T2DM risk across 1-h PG groups: <155, 155–208, and ≥209 mg/dL. T2DM polygenic risk scores (PRS) were stratified into low (1st quintile), intermediate (2nd–4th quintiles), and high (5th quintile). Lifestyle was evaluated using Life’s Essential 8.
Results
Compared to the <155 mg/dL group, hazard ratios for T2DM were 3.34 (95% confidence interval [CI], 2.99 to 3.74; P<0.001) for 155–208 mg/dL, and 6.81 (95% CI, 5.81 to 7.98; P<0.001) for ≥209 mg/dL. Both groups had lower baseline disposition index compared to the <155 mg/dL group (57.3% and 72.7%, respectively; both P<0.001). Higher T2DM PRS was associated with elevated baseline 1-h PG (low: 131 mg/dL, intermediate: 141 mg/dL, high: 151 mg/dL) and faster increase in 1-h PG (1.36 vs. 1.85 vs. 2.21 mg/dL/year; all P<0.001). Importantly, healthy lifestyle attenuated the increase in rate across all PRS groups.
Conclusion
High 1-h PG predicts T2DM risk and is associated with β-cell dysfunction. The 1-h PG level is influenced by genetic risk and can be modified with a healthy lifestyle.

Background
To assess the association of accelerometer-measured sleep regularity with macrovascular and microvascular complications among individuals with type 2 diabetes mellitus (T2DM).
Methods
A total of 3,862 participants with T2DM at baseline participated. The sleep regularity metrics measured by wrist-worn accelerometers include sleep regularity index (SRI) and standard deviation (SD) of sleep duration. Incident macrovascular complications including coronary heart disease (CHD) and stroke, microvascular complications including diabetic neuropathy, diabetic kidney disease, and diabetic retinopathy were recorded. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for macrovascular and microvascular complications.
Results
During a median follow-up of 7.2 years, 410 composite macrovascular and 615 composite microvascular events occurred. Compared to regular sleepers (the highest tertile of SRI), irregular sleepers were at higher risk of composite macrovascular complications (HR, 1.29; 95% CI, 1.01 to 1.66) and stroke (HR, 1.97; 95% CI, 1.08 to 3.58). Compared to regular sleepers (the lowest tertile of sleep duration SD), irregular sleepers were at higher risk of composite macrovascular complications (HR, 1.44; 95% CI, 1.12 to 1.84), CHD (HR, 1.40; 95% CI, 1.07 to 1.82), and stroke (HR, 2.07; 95% CI, 1.13 to 3.81). For microvascular complications, no significant association of sleep regularity metrics was found (all P>0.05). However, the dose-response analysis suggested a potential nonlinear association between SRI and diabetic neuropathy, with lower SRI consistently associated with higher risk of diabetic neuropathy (HR, 1.92; 95% CI, 1.28 to 2.88; 5th percentile vs. 50th percentile).
Conclusion
An irregular sleep pattern across days is clinically relevant for increasing the risk of macrovascular complications and diabetic neuropathy among individuals with T2DM.

Background
Exercise positively influences glycemic control. Some individuals experience greater glycemic stability on the day after exercise, even without additional physical activity. However, the mechanisms underlying this delayed glycemic improvement remain unclear.
Methods
Seventy-one patients with type 2 diabetes mellitus were assigned to either a 60-minute exercise group or a resting group. Serum fibroblast growth factor 21 (FGF21) levels and untargeted metabolomic profiles were assessed at multiple time points before and after exercise. Interstitial glucose levels were monitored using continuous glucose monitoring system. FGF21 knockout mice and wild-type littermates fed a high-fat diet underwent a 3-week exercise intervention and received FGF21 supplementation.
Results
Individuals exhibiting delayed glycemic improvement (responders) displayed a significantly stronger FGF21 response than non-responders. Baseline metabolites, including p-cresol sulfate and dimethylglycine, differed between responders and non-responders and were associated with the FGF21 response. Longitudinal time-series analyses revealed post-exercise differences in acylcarnitines, fatty acids, and complex lipids between responders and non-responders. Dynamic correlation and mediation analyses supported the role of FGF21 in modulating delayed glycemic improvement through regulation of lipid metabolism. In vivo FGF21 knockout and rescue experiments demonstrated that FGF21 is necessary for these metabolic shifts and the associated improvements in glucose tolerance and insulin sensitivity.
Conclusion
This study suggests that the baseline metabolome is associated with the magnitude of the post-exercise FGF21 response, which influences delayed glycemic improvement through regulation of lipid metabolism pathways.

Background
The increasing prevalence of type 2 diabetes mellitus (T2DM) worldwide highlights the need for understanding risk factors and effective prevention strategies. While individual lifestyle factors associated with diabetes risk have been identified, research on their collective interactions is limited. This study aimed to identify lifestyle combination patterns in middle-aged Korean men and evaluate their impact on T2DM risk.
Methods
A total of 2,332 middle-aged men without T2DM at baseline (2001–2002) from the Korean Genome and Epidemiology Study (KoGES) cohort were included. T2DM incidence was tracked through the 8th follow-up (2017–2018). Lifestyle combination patterns were identified using factor analysis based on sociodemographic, lifestyle, and dietary data. Cox regression assessed T2DM incidence across patterns.
Results
Four lifestyle combination patterns were identified: ‘Healthy Lifestyle,’ ‘Low Carb & High Protein,’ ‘High SES & Irregular Lifestyle,’ and ‘Bad Eating Habits.’ The risk of developing T2DM varied across patterns. The ‘Healthy Lifestyle’ and ‘Low Carb & High Protein’ patterns showed a slight decrease in risk in T3, but differences were not significant. The ‘High SES & Irregular Lifestyle’ pattern was associated with higher T2DM risk in T3 versus T1 (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.05 to 1.55), but the association disappeared after adjustment for family history. The ‘Bad Eating Habits’ pattern showed a 1.21-fold higher risk in T3 (HR, 1.21; 95% CI, 1.01 to 1.47).
Conclusion
This study underscores the existence of distinct lifestyle combination patterns and their differential implications for T2DM risk. These findings support the need for tailored preventive strategies based on lifestyle patterns.

Background
Hypertension and diabetes mellitus (DM), including pre-hypertension and impaired fasting glucose (IFG), are associated with increased risk of sudden cardiac arrest (SCA). However, interaction between hypertension and DM needs further examination.
Methods
This study utilized data from the South Korean national healthcare insurance system. People who underwent nationwide health screening in 2012 were enrolled. The impact of blood pressure on SCA was evaluated in both diabetic and non-diabetic patients.
Results
A total of 4,593,706 people were analyzed with 3,097,423, 1,034,563, and 461,720 people included in non-DM, IFG, and DM group, respectively. Both high blood pressure (systolic, diastolic, and pulse) and DM were associated with an increased risk of SCA with the highest absolute risk observed in patients with both conditions. A significant interaction was found between blood pressure and DM (P for interaction <0.01): the relative influence of blood pressure on SCA risk was greater in the non-diabetic population. Importantly, in diabetic patients, a J-shaped association was observed; not only high but also low systolic blood pressure (<100 mm Hg) was associated with a significantly increased risk of SCA.
Conclusion
Although the risk of SCA was highest in people with both hypertension and DM, the degree of association between blood pressure and SCA was more pronounced in non-diabetic people. In patients with diabetes, both high and low systolic blood pressure are associated with an elevated risk of SCA. While controlling hypertension is crucial for all individuals, avoiding hypotension may be another important strategy for preventing SCA in diabetic population.

Background
Data on the familial occurrence of type 1 diabetes mellitus (T1DM) in Korean pediatric populations are limited. This study evaluated the clinical characteristics of children with T1DM according to family history and estimated the T1DM prevalence among relatives.
Methods
We conducted a multicenter retrospective cohort study including patients aged ≤18 years newly diagnosed with T1DM at 18 university-affiliated hospitals in Korea between 2010 and 2024. The index child was defined as the first sibling diagnosed with T1DM and categorized according to the presence of affected parents or siblings. Familial T1DM prevalence was calculated for siblings, first-degree relatives, and twin pairs.
Results
Among 936 index children, 32 (3.4%) exhibited a T1DM family history. Compared with index children, subsequent-affected children presented with lower plasma glucose (300.0 mg/dL vs. 412.0 mg/dL, P=0.009) and glycosylated hemoglobin levels (10.4% vs. 12.6%, P<0.001), and a lower frequency of diabetic ketoacidosis (13.8% vs. 49.7%, P<0.001). Venous pH and serum bicarbonate levels were higher (7.4 vs. 7.3, P=0.005; 22.0 mmol/L vs. 17.0 mmol/L, P=0.004, respectively), whereas urine ketone levels were significantly lower (P<0.001). Sibling, first-degree relative, and twin-pair prevalence rates were 3.0% (23/779), 1.3% (34/2,651), and 42.9% (3/7), respectively.
Conclusion
In this multicenter Korean cohort, familial T1DM accounted for 3.4% of pediatric cases, which was lower than in Western populations. Subsequent-affected children exhibited milder metabolic decompensation at diagnosis than did index children, likely reflecting earlier recognition through family awareness and screening. These findings underscore the importance of early education and monitoring of at-risk relatives within affected families.

The global surge in type 2 diabetes mellitus (T2DM) requires a thorough understanding of pancreatic β-cell dysfunction, which remains a central determinant of the disease. However, the evaluation of β-cell insulin secretory capacity is often challenging in clinical practice due to its inherent complexity. This review presents a comprehensive technical overview of diverse assessment methodologies, ranging from conventional fasting-based indices and glucose tolerance tests to advanced mathematical modeling and artificial intelligence-driven approaches. A detailed examination of the methodological strengths and limitations of these various tools is provided to guide their appropriate clinical application. Furthermore, we explore the clinical implications of these assessments in enhancing diagnostic accuracy and tailoring therapeutic strategies. Particular emphasis is placed on the pivotal role of β-cell function evaluation in predicting and achieving diabetes remission—an emerging clinical priority. By integrating the technical landscape of β-cell assessment with practical applications, this review provide a structured framework for optimizing T2DM management and improving long-term patient outcomes.

Adipose stromal and progenitor cells (ASPCs) represent the largest cell population in human white adipose tissue (WAT). Despite their abundance, ASPC heterogeneity remains less well characterized compared to adipocytes or immune cells. Recent single-cell transcriptome studies provide unprecedented resolution of ASPC diversity and function. This review summarizes state-of-the-art approaches, including high-resolution single-cell methods, classical lineage and functional assays, to define ASPC populations. By systematically comparing recent datasets, we identify evidence for at least eight distinct ASPC-subtypes, which demonstrate specific marker genes and putative functional diversity. Along the adipogenic trajectory, these include uncommitted multipotent progenitors, intermediate and committed preadipocytes, and premature adipocytes. Additional populations comprise specialized anti-adipogenic, profibrotic, inflammatory, and fibroblast-like ASPCs. Other cell types are not consistently detected across studies, reflecting both biological and methodological variability, and the need for further validation studies. Better understanding of ASPC heterogeneity may improve the clinical assessment of metabolic disorders and support their treatment. We further discuss subtype-specific (dys)functions linked to fibrosis, inflammation and impaired adipogenesis and describe their increased abundance in metabolic disease. Together, this review integrates current knowledge on ASPC heterogeneity and highlights its clinical relevance, aiming to provide a unified framework for future studies on WAT remodeling and metabolic dysfunction.

Background
We evaluated epidemiologic trends and clinical characteristics in Koreans with diabetes and obesity and in those with diabetes in pregnancy.
Methods
We analyzed Korea National Health and Nutrition Examination Survey data (2012–2023) to assess obesity trends in people with diabetes and used the Korean National Health Insurance Service database (2013–2023) to evaluate diabetes in pregnancy.
Results
Among Korean adults with diabetes (≥19 years), 52.4% had obesity and 61.1% had abdominal obesity. Only 39.9% achieved the glycemic target (glycosylated hemoglobin <6.5%). The obesity prevalence was higher in younger age groups, and abdominal obesity showed an upward trend over the last 12 years. Diabetes in pregnancy increased despite declining total births, with gestational diabetes mellitus (GDM) rising from 7.6% to 12.4%, and pregestational diabetes from 0.9% to 2.1%, reflecting older maternal age and pre-pregnancy obesity. Women with prior GDM had a higher risk of postpartum type 2 diabetes mellitus (hazard ratio, 6.07; 95% confidence interval, 5.97 to 6.17).
Conclusion
Obesity and abdominal obesity are highly prevalent among Korean adults with diabetes, with abdominal obesity increasing over the past decade, and obesity disproportionately affects younger adults. Diabetes in pregnancy has also increased with older maternal age and worsening pre-pregnancy metabolic health, underscoring the need for early weight-focused prevention.

Background
The growing burden of obesity has profoundly influenced the epidemiology and phenotype of diabetes. This study aimed to compare the epidemiology and clinical features between obese and non-obese diabetes in Korean adults using nationwide database.
Methods
We analyzed data from the Korea National Health and Nutrition Examination Survey (2012–2023) to evaluate the prevalence and management of diabetes, as well as associated comorbidities. Data from the Korean National Health Insurance Service were used to assess antidiabetic medication use, metabolic surgery trends, and cancer outcomes.
Results
Diabetes prevalence was nearly twice as high in adults with obesity compared with those without (17.6% vs. 9.5%), with the larger difference observed in individuals aged 30 to 59 years. Obese diabetes was associated with higher rates of hypertension and dyslipidemia and lower rates of achieving glycemic, blood pressure, and lipid targets; only 21.0% achieved all three goals. Although sodium-glucose cotransporter 2 inhibitors and thiazolidinediones were more frequently prescribed in obese diabetes, overall use remained low. Metabolic surgery was less common in individuals with diabetes than in those without; sleeve gastrectomy predominated, while Roux-en-Y gastric bypass was performed more often in those with diabetes. Higher body mass index was associated with increased incidence of thyroid, breast, prostate, and kidney cancers.
Conclusion
Obese diabetes represents a distinct, high-risk phenotype in Korea, characterized by a greater cardiometabolic burden and suboptimal risk-factor control. Comprehensive management strategies integrating weight reduction with metabolic and cardiovascular risk control are essential to improve outcomes in this population.

Background
This study aimed to investigate the relationship between changes in physical activity patterns following a new diagnosis of type 2 diabetes mellitus (T2DM) and the risk of developing depression.
Methods
This study used comprehensive diabetes data from the National Health Insurance Service of South Korea. From this dataset, we included 254,619 individuals newly diagnosed with T2DM between 2009 and 2015 who had health examination data within 2 years before and after their diagnosis date and no prior history of depression. Physical activity levels were quantified using the metabolic equivalent of task (MET) method.
Results
Compared with individuals with 0 MET-min/wk of physical activity before a new T2DM diagnosis, those who increased their activity levels to 500–999 MET-min/wk after diagnosis showed a 23% reduction in the risk of depression, while an increase to ≥1,000 MET-min/wk was associated with a 25% reduction in depression risk. Conversely, individuals with 1–499 MET-min/wk before diagnosis who became inactive after diagnosis experienced a 25% increased risk of depression. A similar trend toward increased depression risk was observed among those who reduced their physical activity from 500–999 or ≥1,000 MET-min/wk.
Conclusion
Changes in physical activity levels before and after a new diagnosis of T2DM significantly influence the risk of developing depression, with increased activity reducing the risk and decreased activity elevating it. This finding underscores the importance of encouraging physical activity to support mental health in patients with newly diagnosed T2DM.

Background
Regional fat distribution is a key determinant of metabolic risk, independent of total adiposity. However, the developmental origins of fat depot-specific accumulation and its contribution to type 2 diabetes mellitus (T2DM) remain unclear. We aimed to investigate whether adult fat distribution mediates the association between birth weight (BW) and T2DM risk.
Methods
We analyzed 30,718 diabetes-free UK Biobank participants with magnetic resonance imaging/dual-energy X-ray absorptiometry derived measures of visceral adipose tissue (VAT), abdominal subcutaneous adipose tissue, and gynoid adipose tissue (GAT), liver fat fraction (LFF), pancreatic fat fraction (PFF), and muscle fat infiltration (MFI). Fat depots were adjusted for body mass index (BMI) using sex-specific residuals. Cox regression assessed associations of BW and fat depots with T2DM risk. Mediation analysis assessed indirect effects of fat distribution.
Results
Lower BW was associated with a higher risk of T2DM (hazard ratio per 1 kg increase, 0.71; 95% confidence interval, 0.64 to 0.79), with stronger effects in women. Lower BW was linked to greater VAT, LFF, and PFF, and lower GAT, independent of BMI. Higher levels of VAT, LFF, and PFF were associated with increased T2DM risk, while GAT was protective. Mediation analysis revealed that fat distribution partially mediated the BW-T2DM relationship, with LFF showing the strongest mediation effect (11%). Mediation patterns differed by sex: LFF and VAT were the predominant mediators in women, while LFF and GAT contributed substantially in men.
Conclusion
Fat distribution—particularly liver and visceral fat—partially mediates the BW-T2DM relationship, independent of BMI. These findings highlight the clinical importance of fat depot profiling in understanding the developmental origins of diabetes and guiding early risk stratification.

Background
Diabetic kidney disease (DKD) often progresses to end-stage renal disease more rapidly than nondiabetic kidney disease because of persistent hyperglycemia and early activation of multiple pathogenic pathways. Early detection of DKD is crucial for identifying subtle kidney damage before clinical symptoms appear.
Methods
This study combined human serum proteomics with public single-cell RNA sequencing and spatial transcriptomics data from diabetic kidneys to identify key biomarkers for DKD diagnosis. These biomarkers were validated in multiple organs of db/db mice at early and advanced stages. In a discovery cohort, sera from 173 healthy adults and 444 patients with type 2 diabetes mellitus (T2DM), with or without kidney disease, were analyzed using metabolomics and enzyme-linked immunosorbent assay (ELISA). Multiple machine learning algorithms were developed to integrate synergistic biomarkers and serum metabolites for early DKD detection, with results validated in 435 participants from four independent clinical cohorts.
Results
Metalloproteinase-7 (MMP-7) and tenascin C (TNC) were elevated in human diabetic kidneys at the single-cell and spatial levels. Proteomics indicated upregulation of serum amyloid A1 (SAA1) and TNC in the serum of patients with DKD. In db/db mice, all three biomarkers increased in multiple organs by 18 weeks of age. In sera from patients with DKD, MMP-7 and TNC levels were consistently elevated across cohorts. The new algorithms combining MMP-7, SAA1, and TNC enhanced early-stage DKD detection, with approximately 13% improvements in accuracy when serum metabolites were included to distinguish progression from early to advanced DKD stages.
Conclusion
Integrating synergistic biomarkers with serum metabolomics enhances the early detection of DKD, potentially improving outcomes by slowing disease progression in patients with T2DM.

Background
Excess intake of added sugars contributes to obesity, type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), and premature mortality. Sugar-sweetened beverages (SSBs), the main source of added sugars, are consistently linked to adverse outcomes. Artificially sweetened beverages (ASBs) have been suggested as short-term substitutes, but evidence regarding benefits and harms remains inconclusive, and guidance is lacking.
Methods
This consensus statement draws on a structured evidence review combining two approaches: an updated meta-analysis of randomized controlled trials (RCTs) assessing short- to intermediate-term effects of replacing SSBs with ASBs on weight and metabolic outcomes; and an umbrella review of systematic reviews of cohort studies evaluating long-term associations of SSBs and ASBs with major outcomes, including mortality, CVD, and T2DM.
Results
In 14 RCTs (3–76 weeks), replacing SSBs with ASBs produced modest reductions in body weight (–0.73 kg) and body fat (–0.72%), with inconsistent effects on glycemic and cardiometabolic markers. Evidence from 20 systematic reviews of cohorts (up to 34 years follow-up) showed that higher intake of both SSBs and ASBs was associated with increased risks of T2DM, CVD, and mortality, with relative risks for ASBs similar to those for SSBs.
Conclusion
ASBs may serve as a short-term substitution for individuals with high SSB intake, particularly those at elevated metabolic risk. However, regular or long-term use is not recommended due to uncertain safety and potential reinforcement of sweet preference. Public health strategies should emphasize reducing both SSBs and ASBs, prioritizing water and unsweetened beverages as the ultimate goal.

Background
This study assessed the efficacy and safety of HD-6277, a novel oral G protein-coupled receptor 40 (GPR40) agonist in adults with inadequate control of type 2 diabetes mellitus (T2DM).
Methods
This double-blind, randomized, placebo-controlled phase 2 trial recruited 112 individuals aged 18–75 years with T2DM and glycosylated hemoglobin (HbA1c) levels between 7.0% and 10.0% while on diet and exercise alone for at least 8 weeks before screening. Parallel-group randomized trials of HD-6277 (50 and 100 mg groups vs. placebo) were conducted for 12 weeks. The primary outcome was the change in HbA1c levels from baseline to week 12. Secondary outcomes included changes in HbA1c, fasting plasma glucose (FPG), postprandial glucose, insulin, glycoalbumin, and C-peptide at weeks 4, 8, and 12.
Results
At week 12, HD-6277 at 50 and 100 mg demonstrated statistically significant reductions in HbA1c compared to placebo, with least square (LS) mean differences of –0.73% (95% confidence interval [CI], –1.11 to –0.35; P=0.0002) and –0.85% (95% CI, –1.21 to –0.50; P<0.0001), respectively. Both doses also produced clinically meaningful reductions in FPG. Additionally, HD- 6277 at 100 mg significantly increased the insulinogenic index compared to placebo, with an LS mean difference of 1.91 (95% CI, 0.34 to 3.48; P=0.0175). No clinically relevant treatment-related adverse events were observed.
Conclusion
HD-6277 at 50 and 100 mg improved glycemic control and was well-tolerated in adults with T2DM inadequately managed with diet and exercise. GPR40 agonists may offer a promising new therapeutic option for T2DM.

Background
The study evaluated the efficacy and safety of enavogliflozin, a novel, promising selective sodium-glucose cotransporter 2 inhibitor, as an add-on in adults with type 2 diabetes mellitus (T2DM) inadequately controlled with insulin alone or combined with other antidiabetic drugs (OADs).
Methods
The double-blind, placebo-controlled, multicenter trial was conducted in South Korea and Thailand. Individuals with glycosylated hemoglobin (HbA1c) ≥7.5% after ≥8-week treatment with background insulin alone or combined with ≤2 OADs were randomized to receive enavogliflozin 0.3 mg or placebo (n=116 each) for 24 weeks. The primary outcome was a change in HbA1c at week 24. Secondary outcomes included, among others, changes in body weight, blood pressure, and other measures of glycemic control. Adverse events (AEs) were investigated throughout the study (Clinical trial registration number: NCT05466643).
Results
At week 24, the placebo-adjusted mean change in HbA1c from baseline in the enavogliflozin group was –0.9% (P<0.001). Also, placebo-adjusted mean changes in fasting plasma glucose (–32.4 mg/dL, P<0.001), body weight (–1.3 kg, P<0.001), and total daily dose of insulin (–1.3 units, P=0.010) at week 24 were statistically significant. In addition, a significant decrease in blood pressure and fasting C-peptide was observed in the enavogliflozin group, along with a significant increase in homeostasis model assessment of β-cell function, yet without a concomitant change in homeostasis model assessment of insulinresistance. No significant increase in treatment-related AEs was observed for enavogliflozin.
Conclusion
Enavogliflozin 0.3 mg/day is an efficacious and safe add-on treatment option in T2DM patients controlled inadequately with insulin alone or combined with OADs.

Background
Diabetes is a multifactorial disease with significant genetic predisposition. Polygenic risk scores (PRS) have been developed to estimate an individual’s genetic risk of a disease. Traditionally, PRS utilize sex-combined genome-wide association studies (GWAS) due to the limited availability of sex-stratified summary statistics. This study explores sex-dimorphic genetic effects and evaluates the potential benefits of incorporating sex-stratified effects in PRS for type 2 diabetes mellitus (T2DM) and glycemic traits by comparing PRS performance derived from sex-combined versus sex-stratified GWAS.
Methods
We performed a sex-heterogeneity test across sex-specific GWAS and identified nine signals with sex-dimorphic effects for T2DM. PRS[sex-combined] and PRS[sex-stratified] were developed using sex-combined and sex-stratified GWAS results for T2DM (41,444 cases and 354,539 controls), fasting glucose (n=120,595) and fasting insulin (n=98,210). We evaluated these PRS models in 8,379 participants (1,303 cases and 7,076 controls) from the Framingham Heart Study not included in the PRS derivation.
Results
Our findings suggest that sex-combined PRS currently offer better predictive performance for T2DM and glycemic traits.
Conclusion
These results highlight the need for larger sex-stratified studies and the optimization of sex-stratified risk models for clinical practice.

Background
Bariatric metabolic surgery (BMS) has been established as an effective intervention for obesity and type 2 diabetes mellitus (T2DM). However, systematic research addressing the onset of diabetes and post-surgical remission in severely obese populations remains scarce. This study aims to identify risk factors for T2DM in populations with severe obesity undergoing BMS and develop and validate a prediction model for the primary outcome of diabetes remission (DR) 1 year after BMS. This research provides a precise tool for managing T2DM in populations with severe obesity.
Methods
This research utilizes the China Obesity and Metabolic Surgery Database, retrospectively analyzing 3,670 severely obese populations who underwent BMS between January 2014 and January 2024. Differential analysis identified risk factors for T2DM onset, while univariate and multivariate regression analyses identified independent risk factors for DR post-surgery. A prediction model for DR was developed and internally validated.
Results
Factors associated with T2DM onset in severely obese populations included family history of diabetes, hypertension, hyperlipidemia, glycosylated hemoglobin (HbA1c) levels, and fasting plasma glucose. Independent factors influencing DR postsurgery included diabetes duration, surgical method, HbA1c, and insulin requirement. Subsequent model validation confirmed stable performance metrics (area under the curve values training, 0.71; validation, 0.72).
Conclusion
This study identifies risk factors for T2DM onset and a prediction model for DR following BMS in the Chinese severely obese population. It provides a more precise risk assessment tool for patients with severe obesity and T2DM, and lays the groundwork for future multicenter studies and international collaborations.

Background
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improve glycemic control through insulinotropic and anorectic effects. However, the role of adipokines and appetite-related hormones in mediating the glycemic response remains unclear. This study evaluated changes in abdominal fat, food cravings, and circulating adipokines and gut hormones following dulaglutide treatment and identified predictors of glycemic improvement in type 2 diabetes mellitus (T2DM).
Methods
In this 24-week prospective observational study, 82 patients with T2DM and glycosylated hemoglobin (HbA1c) levels ≥7.0% despite standard therapy received dulaglutide 0.75 mg once weekly. Abdominal computed tomography, the General Food Cravings Questionnaire-Trait, and fasting levels of leptin, adiponectin, obestatin, ghrelin, and resistin were assessed at baseline and week 24. Glycemic responders were defined as those with an HbA1c reduction ≥0.5% and/or HbA1c <7.0% at 24 weeks. Multivariable regression analysis was performed to identify the factors associated with glycemic improvement.
Results
Among the 67 patients who completed the study, dulaglutide significantly reduced HbA1c, food cravings, leptin, and adiponectin levels. Obestatin levels increased modestly. Responders showed greater improvement in β-cell function and more pronounced reductions in food cravings. In the adjusted models, a decrease in leptin and an increase in obestatin were independently associated with HbA1c reduction, while decreased adiponectin was associated with poorer glycemic outcomes. Changes in body mass index or abdominal fat were not associated with glycemic improvement.
Conclusion
Dulaglutide improved glycemic control through mechanisms beyond weight reduction. Hormonal changes in leptin, adiponectin, and obestatin may help predict responses to GLP-1 RAs therapy.

Background
In this study, we aimed to validate the potential of miR-374 in ameliorating hyperglycemia by regulating peroxisome proliferator-activated receptor γ coactivator-1 (PGC-1α) expression in pancreatic islets and liver.
Methods
To identify miRNAs targeting PGC-1α, we performed miRNA chip analysis in rat islets under hyperglycemic and euglycemic conditions. Luciferase reporter assay was performed to identify miR binding sites in the 3’-untranslated region (3’ UTR) of PGC-1α. In db/db mice, miRNA-encapsulated adenoviruses were administered and intraperitoneal glucose tolerance test and glucose stimulated insulin secretion tests were performed. For enhanced delivery to β-cells, we developed exendin-4 (Ex-4) coated cationic lipoparticles (CCLs) encapsulating miRNAs. The therapeutic potential of Ex-4-CCL-miRNA was further evaluated in insulin-producing cells derived from induced pluripotent stem cells.
Results
By analyzing miRNA expression in primary rat islets exposed under hyperglycemic environment, we identified miR-374 as a potential target. In vitro experiments confirmed that miR-374 significantly suppressed PGC-1α expression in β-cells and hepatocytes by binding to its 3’-UTR. In vivo experiments using adenovirus-mediated miR-374 (Ad-miR-374) delivering directly to the pancreas and liver of db/db mice demonstrated improved glycemic control, enhanced insulin secretion, and downregulated hepatic gluconeogenesis-related genes (G6Pase, Pepck, PC). To enhance the clinical applicability of miR-374, we developed Ex-4-CCLs. Ex-4-CCL-miR-374 successfully alleviated hyperglycemia, restored pancreatic islet function, and decreased gluconeogenesis gene expression in db/db mice. Furthermore, Ex-4-CCL-miR-374 improved insulin secretory function in glucotoxicity-exposed human induced pluripotent stem cell-derived insulin producing cells.
Conclusion
Based on these findings, we propose that Ex-4-CCL-miR-374 as a promising therapeutic approach to reverse β-cell dysfunction and improve hepatic insulin resistance in type 2 diabetes mellitus.

Background
Diabetic foot ulcers are a severe diabetic complication characterized by poor healing. Itaconate, a tricarboxylic acid cycle byproduct, has been shown to improve wound healing. This study investigated the potential of 4-octyl itaconate (4-OI), an esterified derivative of itaconate, to modulate efferocytosis and macrophage pro-resolving function to promote diabetic wound healing.
Methods
A diabetic mouse wound model was used. For in vitro analysis, RAW264.7 macrophages and apoptotic Jurkat cells were cocultured under high glucose conditions (HG, 30 mM). To further evaluate the roles of macrophages, monocarboxylate transporter 1 (MCT1), and lactate in 4-OI-promoted diabetic wound healing, we used clodronate-liposomes (CLD-Lipo) to deplete macrophages, AZD3965 as an MCT1 inhibitor, and telmisartan to validate our hypothesis.
Results
In diabetic mice, impaired clearance of apoptotic neutrophils and persistent M1 activation delayed wound healing. 4-OI improved diabetic wound repair by enhancing efferocytosis, shifting macrophages toward an M2 pro-resolving phenotype, and boosting angiogenesis. 4-OI showed a protective effect mediated by macrophages, while endothelial cells and neutrophils also played synergistic roles in diabetic wound healing. Moreover, 4-OI upregulated MCT1, which, in turn, increased the release of lactate triggered by efferocytosis at the wound site. Lastly, we confirmed that the pro-resolving effects of 4-OI onmacrophage function were mediated by promoting pro-resolving macrophage proliferation and polarization via efferocytosis-induced lactate release and subsequent activation of G protein-coupled receptor 132 (GPR132).
Conclusion
4-OI promotes diabetic wound healing through macrophage-dependent and macrophage-independent mechanisms. Moreover, the protective effect of 4-OI on macrophages was mediated through MCT1-mediated lactate release triggered by efferocytosis and subsequent GPR 132 activation.

This Korean Diabetes Association (KDA) consensus statement bridges global evidence with the Korean clinical context, where large randomized and real-world data remain limited. Recommendations required ≥80% agreement by the committee of clinical practice guideline and approval by the board of directors. The statement comprises three domains: diabetes screening aligned with Korean epidemiology; pharmacologic management guided by pathophysiology and comorbidities; and a severity construct of “severe diabetes mellitus” that links complication-based staging with metabolic grading to match therapeutic intensity to disease complexity. Compared with prior KDA guidelines, this statement introduces substantive advances in three areas. First, screening recommendations are streamlined to emphasize risk-aligned, practical implementation rather than prescriptive test sequences. Second, pharmacologic management applies an individualized framework for drug selection that jointly considers pathophysiology and comorbidities. It operationalizes individualized selection by dominant pathophysiology (insulin resistance vs. insulin insufficiency) and coexisting conditions, and formalizes treatment dynamics—early combination, timely initiation of injectables, avoidance of overbasalization, and structured deintensification. It also prioritizes agents with proven cardiovascular and renal protection and elevates management of obesity and metabolic dysfunction-associated steatotic liver disease as central goals; clinically, insulin should be initiated promptly in hypercatabolic states or suspected islet failure, and technology-enabled care—including continuous glucose monitoring and automated insulin delivery—are integral across all stages. Third, the newly introduced severity construct underpins treatment-intensity decisions across domains without reiterating prescriptive algorithms. Collectively, these recommendations provide a coherent, context-appropriate framework for diabetes screening and management in Korea and identify priorities for future evidence generation.

The increasing prevalence of diabetes among older adults has emerged as a major socioeconomic burden. This population is highly heterogeneous, ranging from functionally independent to severely impaired individuals, making it difficult to establish standardized recommendations. Physical activity (PA) is a cornerstone of diabetes management; however, current exercise guidelines do not adequately address the wide spectrum of functional capacities observed in older adults. For those with physical limitations, relatively simple activities such as walking, breaking up sedentary time, incorporating movement into daily routines, and aquatic exercise have been proposed, yet supporting evidence remains limited. This review summarizes the pathophysiologic mechanisms of metabolic and functional changes associated with aging and diabetes—including sarcopenia, altered body composition, and cardiovascular decline—and comprehensively discusses the benefits and precautions of various exercise modalities, tailored recommendations according to diabetes-related complications, and key clinical considerations. We further classified older adults with diabetes into three functional levels, individuals in good health, those with some comorbidities or mild disabilities, and those with high comorbidities and/or functional impairment, and proposed corresponding physical activity strategies for each level. Finally, we highlight practical and feasible approaches, including walking, interrupting sedentary behavior, daily functional movements, and aquatic exercise, to enhance clinical applicability for individuals with reduced physical capacity. These tailored, function-based strategies may help older adults with diabetes achieve safer, more effective, and sustainable improvements in glycemic control and overall health.

Diabetes mellitus comprises a heterogeneous group of metabolic disorders differing in etiology, clinical course, and outcomes. Traditional classifications, such as type 1 and type 2 diabetes mellitus, fail to capture the full heterogeneity, including variation in insulin deficiency, insulin resistance, and complication burden. To address these limitations, we propose the Diabetes Grade–Stage Classification, an integrated system that combines pathophysiology-based grading with complication-based staging. Grading quantifies metabolic dysfunction through the assessment of insulin deficiency and insulin resistance. In parallel, staging assesses the extent of target organ damage, particularly in the cardiovascular, renal, ocular, and nervous systems. Together, this framework enables a comprehensive assessment of disease status, identification of vulnerable or high-risk phenotypes, and implementation of risk-adapted management strategies. Clinically, it facilitates personalized care, promotes collaborative coordination, and strengthens physician–patient communication. Furthermore, this framework provides a scalable structure for integrating disease severity into both individual- and population-level interventions. Although the current criteria for grading and staging are based on expert consensus and selected clinical indicators, such as low C-peptide levels and advanced complications, further validation and refinement are needed. In conclusion, the grading and staging system provides an operational tool for classifying the severity of diabetes mellitus and has the potential to extend life expectancy and improve quality of life for people living with diabetes mellitus.

Background
Type 2 diabetes mellitus (T2DM) is a complex, multifactorial disease with a significant global burden. Although genome-wide association studies (GWAS) have identified many T2DM-associated variants, most lie in non-coding regions, making it difficult to interpret their functional roles.
Methods
We aimed to identify genetically regulated Cytosine–phosphate–Guanine (CpG) sites associated with T2DM by conducting a methylome-wide association study (MWAS), followed by Mendelian randomization (MR) and functional validation using human pancreatic cells and mouse models. MWAS was performed using summary statistics from large-scale GWAS and a DNA methylation (DNAm) prediction model to test associations between genetically predicted DNAm and T2DM.
Results
We identified 111 CpG sites significantly associated with T2DM in Europeans, including 8 novel sites near genes not previously linked to T2DM. These findings were replicated in independent datasets. Many CpGs also showed associations with cardiometabolic traits, highlighting shared epigenetic mechanisms. Trans-ethnic MR analysis confirmed consistent effects for six CpGs in East Asians. Functional analysis revealed that several CpGs regulate gene expression in human pancreatic α- and β-cells. Among them, 2´-5´-oligoadenylate synthetase like (OASL) expression, regulated by a significant CpG, was differentially expressed in α-cells of T2DM cases compared to controls. Supporting evidence from mouse models suggests a role for OASL in glucose regulation.
Conclusion
Our study identifies novel genetically regulated CpG sites associated with T2DM risk and highlights OASL as a potential epigenetic regulator of glucose metabolism in α-cells. These findings provide mechanistic insights into the epigenetic architecture of T2DM and suggest potential targets for cross-ethnic biomarker development and therapeutic intervention.

Background
This study investigated the efficacy and safety of pioglitazone 30 mg/day add-on to inadequately controlled type 2 diabetes mellitus (T2DM) patients with treatment of dapagliflozin and metformin.
Methods
In this multicenter (34 sites), double-blind, randomized, phase 3 study, patients with T2DM with an inadequately controlled glycosylated hemoglobin (HbA1c) over 7.0% to treatment with dapagliflozin (10 mg/day) and metformin (≥1,000 mg/day) were randomized to receive additional pioglitazone 30 mg/day (n=124) or placebo (n=122) for 24 weeks. The primary outcome was the mean change of HbA1c from baseline to 24 weeks treatment. The efficacy and safety were evaluated with open label extension period, switching placebo to pioglitazone 30 mg/day at 48 weeks (ClinicalTrials.gov identifier: NCT05296044).
Results
The HbA1c after 24 weeks treatment reduced from 7.8%±0.8% to 7.0%±0.6% (P<0.0001). The proportions of patients who achieved HbA1c less than 7.0% at 24 weeks were significantly higher in pioglitazone add-on group (51.61% in pioglitazone vs. 22.95% in placebo, P<0.0001), or less than 6.5% at 24 weeks (21.77% in pioglitazone vs. 2.46% in placebo, P<0.0001). Body weight gain was 2.0 kg at 24 weeks with pioglitazone 30 mg/day and –0.6 kg at 24 weeks with placebo.
Conclusion
Addition of pioglitazone 30 mg/day to T2DM patients who did not reach the target HbA1c (≤7%) with treatment of dapagliflozin 10 mg/day and metformin over 1,000 mg/day showed effective glucose lowering efficacy without significant hypoglycemia and good tolerability with low prevalence of edema in spite of modest weight gain.

Background
Patients with type 2 diabetes mellitus (T2DM) and coronary ischemia face an exceptionally elevated risk, and the achievement of complete revascularization (CR) within this population could be challenging.
Methods
Patients with T2DM and coronary ischemia based on coronary angiography and retrospective angiographic fractional flow reserve analysis between 2014 and 2016 were included. The impact of the extent of revascularization on the improvement of endpoint events by sodium-glucose cotransporter 2 (SGLT2) inhibitors was analyzed. The primary study endpoint was major adverse cardiac events (MACE), while all-cause mortality served as secondary endpoints. Kaplan-Meier analysis and Cox proportional hazards regression model were adopted to assess the association between SGLT2 inhibitors and endpoint incidence.
Results
A total of 671 patients were identified. Among them, 206 (30.7%) were prescribed with SGLT2 inhibitors, while 484 (72.1%) achieved CR after the operation. During a mean 36-month follow-up, 100 MACE and 89 all-cause mortality were recorded. SGLT2 inhibitor users demonstrated lower rates of MACE (8.3% vs. 17.8%, P=0.002) and all-cause mortality (6.3% vs. 16.3%, P<0.001) compared to non-users. After adjusting for confounding factors in multivariable Cox analysis, the association between SGLT2 inhibitors and reduced MACE incidence remained consistent both in the CR and incomplete revascularization subgroups (hazard ratio [HR], 0.498; 95% confidence interval [CI], 0.246 to 0.938; P=0.040; and HR, 0.341; 95% CI, 0.123 to 0.805; P=0.023, respectively).
Conclusion
SGLT2 inhibitors were found to be associated with a reduced risk of 3-year MACE and all-cause mortality in patients with T2DM and coronary ischemia, regardless of extent of revascularization.

Background
Remnant cholesterol (RC) and low-grade inflammation are established contributors to cardiovascular disease (CVD) risks in diabetes. However, their combined prognostic impact remains unclear in dysglycemia. We evaluated the remnant cholesterol inflammation index (RCII), integrating RC and high-sensitivity C-reactive protein (hsCRP), for predicting mortality and CVD risks in diabetes/prediabetes.
Methods
This study included 2206 United States adults with diabetes/prediabetes from National Health and Nutrition Examination Survey 2015–2018. RCII was calculated as [RC (mg/dL)×hsCRP (mg/L)]/10. All-cause mortality was tracked via National Death Index until 2019; CVD risk was assessed cross-sectionally. Cox proportional hazard regression determined the hazard ratio (HR) and 95% confidence intervals (CIs) of RCII for all-cause mortality. Logistic regression models estimated the odds ratio (OR) and 95% CIs of RCII for CVD risks.
Results
For CVD risks, Q4 vs. Q1 demonstrated increased odds (OR, 2.32; 95% CI, 1.23 to 4.37), though per-standard deviation (SD) increments were non-significant (OR, 1.15; 95% CI, 0.98 to 1.35; P=0.083). During a median of 38 months follow-up, higher RCII quartiles showed graded associations with all-cause mortality (Q4 vs. Q1: HR, 2.45; 95% CI, 1.08 to 5.58; per 1-SD increase: HR, 1.21; 95% CI, 1.08 to 1.35). Restricted cubic splines confirmed dose-dependent relationships for CVD risks and all-cause mortality (all P=0.005 for overall). Subgroup analyses revealed consistent mortality associations but sex-specific CVD interactions (P=0.047 for interaction).
Conclusion
Our study found the RCII as a biomarker for predicting all-cause mortality and CVD risks in individuals with prediabetes or diabetes, highlighting the synergistic effects of RC and low-grade inflammation on adverse outcomes in this population and may facilitate early identification of individuals at heightened risk for CVD.

Background
Contrast-induced acute kidney injury (CIAKI) is the third leading cause of hospital-acquired acute kidney injury and diabetes mellitus (DM) has been identified as a risk factor for CIAKI. However, the molecular mechanism underlying DM-CIAKI remains unclear and requires further investigation.
Methods
Mouse and cell models of DM-CIAKI were established. Kidney function was evaluated by measuring biochemical indicators and using hematoxylin and eosin staining. Gene and protein abundance was assessed using real-time quantitative reverse transcription polymerase chain reaction, immunohistochemistry, immunofluorescence, and Western blotting. Glutathione peroxidase, superoxide dismutase, and malondialdehyde were measured using commercial kits, and reactive oxygen species were detected using a dihydroethidium (DHE) probe and the 2ʹ,7ʹ-dichlorofluorescein diacetate (DCFH-DA) method. Apoptosis in tissues and cells was evaluated by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). Cell viability and proliferation were measured using Cell Counting Kit-8 and 5-ethynyl-2ʹ-deoxyuridine (EdU) assays. The interaction between pumilio RNA binding family member 2 (PUM2) and histone deacetylase 9 (HDAC9) was validated using RNA immunoprecipitation (RIP) and RNA pull-down assays.
Results
PUM2 expression was markedly reduced in DM-CIAKI models, whereas HDAC9 expression was notably increased. Subsequently, PUM2 silencing aggravated kidney injury in DM-CIAKI mice by enhancing oxidative stress and suppressing autophagy, whereas HDAC9 inhibition or HDAC9 silencing had the opposite effects. Mechanistically, PUM2 could suppressed the stability of HDAC9 mRNA, thereby attenuating HDAC9 expression. Furthermore, HDAC9 overexpression abolished PUM2 overexpression-mediated inhibition of oxidative stress and promotion of autophagy in high glucose- and contrast media-treated human kidney-2 (HK-2) cells.
Conclusion
PUM2 overexpression suppressed oxidative stress and promoted autophagy to alleviate renal injury in DM-CIAKI by interacting with HDAC9 mRNA, which mediated HDAC9 and mRNA degradation and inhibited HDAC9 expression.

Background
The long-term clinical efficacy of intraportal islet transplantation is hampered by islet loss due to inflammation, oxidative stress, and insufficient vascularization. This study explores the venous sac as an alternative implantation site for islet transplantation in large animal models.
Methods
An immunosuppressed, diabetic cynomolgus monkey received allogeneic islet implants in its mesenteric venous sac, with metabolic assessments over 112 days. Dogs underwent islet autotransplantation into various venous sacs, with their glycemic control and other metabolic parameters monitored for 1 month.
Results
In a nonhuman primate, the mesenteric venous sac site improved glycemic control over a 3-month period, followed by destabilization of graft function. Histological studies revealed healthy islets. The lack of mononuclear cell infiltrate suggested no signs of graft rejection. Saphenous venous sacs in dogs showed superior glycemic control, reduced insulin requirements, and maintained C-peptide levels, comparable to intraportal transplantation. Histological analyses confirmed islet preservation and graft vascularization in saphenous venous sacs.
Conclusion
This study provides preclinical evidence in support of the venous sac as a valuable extrahepatic location for pancreatic islet implantation. We found that the saphenous vein is a more effective site for islet engraftment than the mesenteric vein. This study offers potential benefits for improving the success rates of clinical islet transplantation.

Background
Central obesity contributes to an increased risk of cardiovascular disease (CVD) and mortality. The waist-to-height ratio (WHtR) is a practical marker of central obesity across sexes, ages, and ethnicities. However, its association with comprehensive cardiovascular (CV) outcomes in patients with type 1 diabetes mellitus (T1DM) remains unclear.
Methods
From a nationwide cohort database (2006–2020), 16,928 Korean adults with T1DM were included. Participants were categorized according to WHtR using three criteria: a three-group classification (<0.5, 0.5 to <0.6, and ≥0.6) and two binary classifications (≥0.5 vs. <0.5; ≥0.6 vs. <0.6). The primary outcome was a composite CV event, including heart failure (HF), myocardial infarction (MI), ischemic stroke, and CVD-related death, with each component analyzed as a secondary outcome.
Results
During a median follow-up of 6.7 years (interquartile range, 5.2 to 8.8), 4,293 composite CV events occurred. Compared with the WHtR <0.5 group, the adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for the composite CV outcome were 1.14 (1.05 to 1.24) in the WHtR 0.5 to <0.6 group and 1.62 (1.38 to 1.90) in the WHtR ≥0.6 group (P for trend <0.001). Increasing trends in aHRs were noted with rising WHtR values for each component of the composite outcome. Compared with the WHtR <0.6 group, the aHRs for the WHtR ≥0.6 group were as follows: HF, 1.49 (95% CI, 1.28 to 1.73); MI, 1.31 (95% CI, 1.02 to 1.68); ischemic stroke, 1.24 (95% CI, 1.02 to 1.51); and CVD-related death, 2.09 (95% CI, 1.49 to 2.92).
Conclusion
High WHtR was associated with an increased risk of CV events in adults with T1DM.

This study evaluated whether a stage 4 smart insulin pen (SIP) provides superior glycemic control compared with a traditional insulin pen (TIP) in individuals with intensively insulin-treated diabetes. Forty-two adults with continuous glucose monitoring (CGM), multiple daily insulin injections, and no prior SIP use were included. After diabetes self-management education (DSME), the SIP group (n=21) initiated SIP, whereas the TIP group (n=21) continued their usual regimens. Glycemic metrics were assessed using CGM before and 2 weeks after DSME. Both groups demonstrated significant improvements in glycemic outcomes. However, SIP users exhibited superior improvements in the percentage of time in range, percentage of time below range (%TBR) <70 mg/dL, %TBR <54 mg/dL, and glycemic risk index compared with TIP users (between-group difference [BD] 11.0%, P=0.046; BD –2.6%, P=0.024; BD –0.9%, P=0.027; BD –18.2, P=0.022, respectively). These findings suggest that SIP, with its bolus calculation and CGM integration, is associated with improved glycemic outcomes in adults with intensively insulin-treated diabetes.

As the prevalence of type 2 diabetes mellitus continues to rise, the development of effective and sustainable prevention strategies has become a critical public health priority. Evidence from large-scale randomized controlled trials has established that lifestyle modification (LSM) programs can substantially reduce the risk of diabetes in high-risk individuals. However, routine implementation is limited by high intensity, costs, and resource requirements. We summarize major prevention trials and their effectiveness, feasibility, and limitations. Building on these insights, we introduce the Korean Diabetes Prevention Study (KDPS) as a contextually tailored model for the Korean healthcare system. The KDPS-LSM program was designed to integrate cultural and clinical relevance with practical applicability, consisting of a 6-month intensive phase of structured nutrition and lifestyle education followed by a maintenance phase to support long-term adherence. To promote sustainable change, the program incorporates the ‘10 habit’ lifestyle messages, grounded in the transtheoretical model of behavior change, which are designed for easy implementation in daily life. This review underscores the importance of developing culturally appropriate LSM programs that balance effectiveness with feasibility, and suggests that the KDPS-LSM model could serve as a useful foundation for establishing practical diabetes prevention strategies within national healthcare systems.

AbstractAbstract PDFPubReader   ePub   
The global prevalence of early-onset type 2 diabetes (EOT2D) is rising rapidly. Adults with EOT2D represent a high-risk population characterised by increased rates of microvascular and macrovascular complications, adverse psychological wellbeing and psychiatric comorbidities such as depression, and premature mortality compared to those with later-onset type 2 diabetes mellitus. This emerging population faces unique challenges, including high levels of diabetes-related stigma, clinical inertia, and competing life demands, such as starting a family. This review synthesises current evidence on the clinical management of EOT2D. Key therapeutic targets include weight reduction, preservation of β-cell function, cardiometabolic risk management, and psychological support. Overall, there are few randomized controlled trials (RCTs) undertaken specifically in adults with EOT2D. However, we summarise early data from the few RCTs that do report outcomes specific in young adults, with bariatric surgery, tirzepatide and intensive lifestyle interventions emerging as particularly effective treatments. There is a strong rationale that technology-based inventions and structured education programs may prove to be effective treatments but data from RCTs is lacking. We provide broad recommendations for future research and clinical practice based on the current evidence. In conclusion, substantial further research is required to inform tailored, evidence-based guidelines and improve long-term outcomes in this underserved population.

Background
Type 2 diabetes mellitus (T2DM) is common among older adults and may increase the risk of sarcopenia and frailty. This study evaluated the impact of sarcopenia and frailty on 5-year mortality in older adults with T2DM.
Methods
We assessed a cohort study of 447 adults with T2DM who were more than 60 years old. Following the guidelines set by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2), we used bioelectrical impedance analysis to measure muscle mass and a handgrip dynamometer to measure muscle strength. We assessed frailty using the Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight (FRAIL) Scale. We categorised the patients into four groups: isolated sarcopenia, isolated frailty, both conditions (sarcopenia and frailty), or neither.
Results
The median age of the patients was 69 years, and 71.6% were female. Isolated sarcopenia was present in 11.0% of patients, isolated frailty in 22.4%, and both sarcopenia and frailty in 9.8%. After adjustment for age, sex, comorbidities, activities of daily living, glycemic control, and nutritional status, sarcopenia and frailty were significantly associated with an increased risk of 5-year mortality. Isolated frailty also significantly predicted mortality (hazard ratio, 2.59; 95% confidence interval, 1.34 to 5.03; P=0.005).
Conclusion
Sarcopenia and frailty were significant predictors of increased mortality risk in older adults with T2DM. Coexisting sarcopenia and frailty posed the highest risk. Early identification and targeted interventions for these conditions in older patients with T2DM are crucial to improving outcomes.

Background
We determined the precise function of E2F transcription factor 5 (E2F5) on the development of diabetic atherosclerosis (DAS) and the underlying mechanisms.
Methods
Apolipoprotein E-knockout mice were intraperitoneally injected with streptozotocin for 5 days and fed a high-fat diet for 12 weeks for establishing an in vivo DAS model. To establish a DAS vascular smooth muscle cells (VSMCs) model, VSMCs were stimulated with fresh medium containing glucose and oxidized low-density lipoprotein. After the final treatment, serum lipids were detected, and aorta tissues were collected for hematoxylin and eosin staining, Western blot, Oil red O staining, and quantitative reverse transcription polymerase chain reaction. The effect of E2F5 on the proliferation, migration, cell cycle, phenotype switching, and cell cycle-related markers of VSMCs were evaluated.
Results
In vivo, the expression of E2F5 was elevated in aortic tissues of DAS mice. The downregulation of E2F5 alleviated the symptoms of DAS in mice. Moreover, E2F5 downregulation inhibited the phenotypic transformation of VSMCs in DAS mice. In vitro, the knockdown of E2F5 inhibited the phenotypic transformation of VSMCs. CyclinE overexpression reversed the inhibitory effect of E2F5 silencing on phenotypic transformation of VSMCs. Additionally, we also found that the treatment of BML-284 significantly attenuated the inhibitory effect of E2F5 silencing on phenotypic transformation of VSMCs.
Conclusion
E2F5 is an injurious factor in the pathogenesis of DAS, and the downregulation of E2F5 could repress VSMCs phenotype switching through inactivating Wnt/β-catenin pathway, and ultimately inhibit the progression of DAS.

AbstractAbstract PDFPubReader   ePub   
Diabetes mellitus predisposes individuals to a broad spectrum of infections. People with diabetes face a 1.5- to 4-fold increased risk of both common and severe infections, and infections remain the leading cause of morbidity and mortality. Chronic hyperglycemia impairs neutrophil chemotaxis, oxidative burst, and complement activation, while vascular insufficiency and neuropathy compromise tissue perfusion and barrier integrity. These defects, together with altered skin, mucosal, and gut microbiota, influence the marked susceptibility to urinary tract infections (especially renal abscess and emphysematous pyelonephritis), osteomyelitis, diabetic foot infections, pneumonia (including influenza), tuberculosis, skin and soft tissue infections, and lifethreatening syndromes such as emphysematous cholecystitis and rhino-orbital mucormycosis that are almost exclusive to people with diabetes. Outcomes from infections are worse in diabetes. Although the core therapeutic principles align with those for patients without diabetes, management should be individualized. Glycemic control should balance infection risk and hypoglycemia; antimicrobial dosing should account for renal function and drug interactions; and strict antimicrobial stewardship is required. If needed, prompt debridement and multidisciplinary intervention are necessary to mitigate complications and reduce mortality. Preventive care relies on comprehensive vaccination (influenza, pneumococcus, severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2], hepatitis B, herpes zoster, and Tdap/Td) and regular foot surveillance with offloading to avert ulceration.

Background
We conducted a prospective, randomized study to evaluate the combination of cilostazol (CTZ) and extract of Ginkgo biloba (EGb) and compare it with aspirin for the prevention of atherosclerosis progression in patients with type 2 diabetes mellitus (T2DM).
Methods
One hundred five patients with T2DM and increased carotid intima-media thickness (IMT) were randomly assigned to receive either CTZ 200 mg plus EGb 160 mg once daily or aspirin (ASA) 100 mg/day for 12 months. The primary endpoint was the change in maximum carotid IMT.
Results
The mean age and body mass index were 61.6±8.4 years and 25.2±3.1 kg/m2 in the CTZ/EGb group and 61.6±7.6 years and 24.5±3.3 kg/m2 in the ASA group, respectively. CTZ/EGb treatment reduced the maximum IMT in the bulb area (from 1.435±0.690 to 1.346±0.688 mm on the right; from 1.359±0.528 to 1.299±0.528 mm on the left), whereas ASA treatment did not, resulting in significant between-group differences (P<0.05). No significant differences were observed in the common carotid and internal carotid arteries. The CTZ/EGb group showed a reduction in triglycerides and an increase in high-density lipoprotein cholesterol levels. Additionally, aspartate and alanine aminotransferase levels decreased only in the CTZ/EGb group. There were no significant differences in Mini-Mental State Examination (MMSE) score changes or adverse events (ClinicalTrials.gov number: NCT05906199).
Conclusion
Twelve months of CTZ/EGb combination therapy significantly attenuated the progression of carotid atherosclerosis compared with aspirin in patients with T2DM.

Background
This study aimed to investigate the modifying effects of rare genetic variants on the risk of type 2 diabetes mellitus (T2DM) in the context of common genetic and lifestyle factors.
Methods
We conducted a comprehensive analysis of genetic and lifestyle factors associated with T2DM in a cohort of 146,284 Korean individuals. Among them, 4,603 individuals developed T2DM during the follow-up period of up to 17 years. We calculated a polygenic risk score (PRS) for T2DM and identified carriers of the rare allele I349F at SLC30A8. A Healthy Lifestyle Score (HLS) was also derived from physical activity, obesity, smoking, diet, and sodium intake levels. Using Cox proportional hazards models, we analyzed how PRS, HLS, and I349F influenced T2DM incidence.
Results
Results showed that high PRS and poor lifestyle were associated with increased risk. Remarkably, I349F carriers exhibited a lower T2DM prevalence (5.7% compared to 11.7% in non-carriers) and reduced the impact of high PRS from 23.18% to 12.70%. This trend was consistent across different HLS categories, with I349F carriers displaying a lower risk of T2DM.
Conclusion
The integration of common and rare genetic variants with lifestyle factors enhanced T2DM predictability in the Korean population. Our findings highlight the critical role of rare genetic variants in risk assessments and suggest that standard PRS and HLS metrics alone may be inadequate for predicting T2DM risk among carriers of such variants.

Background
Menopausal status can increase the risk of cardiocerebrovascular diseases (CCVDs) in women with type 2 diabetes mellitus (T2DM). Regular exercise is well-known to reduce this risk. This study explored the impact of exercise on CCVD and mortality in women with T2DM according to their menopausal status.
Methods
A total of 32,477 premenopausal and 53,690 postmenopausal Korean women with T2DM aged 40 to 60 years from a national health examination cohort (2009 to 2018) were included. We evaluated risks for stroke, myocardial infarction (MI), and mortality based on exercise intensity. Cox proportional hazard regression analyses were performed to obtain the adjusted hazard ratio (aHR) and 95% confidence interval.
Results
Exercise reduced stroke, MI, and mortality risks in women with T2DM, regardless of menopausal status. The highest effects of aHR compared to the sedentary group were 0.68 for stroke, 0.66 for MI, and 0.81 for mortality. Postmenopausal women experienced significant MI risk reductions at most exercise intensities, with the greatest reduction in the ≥1,500 metabolic equivalent of task score group unlike premenopausal women. However, stroke and mortality risk reductions in postmenopausal women were less pronounced compared to premenopausal women.
Conclusion
Exercise reduces CCVD risk in women with T2DM across menopausal status. Postmenopausal women with T2DM had more benefits from exercise on MI but fewer benefits on stroke and mortality than premenopausal women. In premenopausal women with T2DM, exercise was not associated with a lower MI risk.

Background
The potassium voltage-gated channel subfamily Q member 1 (KCNQ1) gene has recently received much attention as a candidate susceptibility gene for type 2 diabetes mellitus, especially in Asian populations. We previously reported that Kcnq1 mutant mice exhibit reduced insulin secretion and hyperglycemia due to a decrease in pancreatic β-cell mass. Through in vivo and in vitro analyses, we ascertained that this mechanism is the result of the downregulation of the non-coding RNA ‘Kcnq1ot1,’ which is expressed in the paternal allele of the Kcnq1 gene region, causing an increase in the expression of the cell cycle inhibitor cyclin dependent kinase inhibitor 1C (Cdkn1c). It was found that decreased Kcnq1ot1 expression resulted in pancreatic β-cell failure; however, the degree of pancreatic β-cell volume reduction was not severe.
Methods
We induced obesity in Kcnq1ot1 truncation mice by feeding them a high-fat diet and evaluated pancreatic β-cell mass.
Results
In the present study, we reveal that CCAAT/enhancer binding protein beta (C/EBPβ), which is expressed at higher levels in pancreatic β-cells in obese individuals, further increases the expression of Cdkn1c, which is upregulated by the Kcnq1 gene mutation. We found that simultaneous Cdkn1c hypomethylation and C/EBPβ overexpression in pancreatic β-cells causes a synergistic decrease in pancreatic β-cell mass.
Conclusion
This finding suggests that the synergistic effect of genetic factors such as Kcnq1 gene mutations and environmental factors such as obesity and overeating, which lead to increased expression of C/EBPβ, contribute to the regulation of pancreatic β-cell mass. This study is the first to show that the Kcnq1 gene is related to pancreatic β-cell mass through genetic-environment interactions.

Background
Preclinical studies have reported anticancer properties of sodium-glucose cotransporter 2 inhibitors (SGLT2is). We aimed to elucidate the association between the use of SGLT2is and the risk of prostate cancer among male patients with type 2 diabetes mellitus (T2DM).
Methods
An active-comparator, new-user cohort design using a nationwide database between September 2014 and June 2020 was conducted on 45,601 new SGLT2i users and 205,395 new users of other glucose-lowering medications (oGLMs). In the following 1:1 propensity score matched (PSM) analysis, 35,371 SGLT2i users matched with an equivalent number of oGLM users were assessed. The hazard ratios (HRs) and 95% confidence intervals (CIs) for prostate cancer were calculated.
Results
Among the cohort, prostate cancer was diagnosed in 210 out of 45,601 SGLT2i users, corresponding to a cumulative incidence of 1.0%, in contrast to 1,880 cases among 205,395 users of oGLMs, with a cumulative incidence of 1.5%. The use of SGLT2is was significantly correlated with a reduced risk of prostate cancer based on a multivariable-adjusted HR of 0.83 (95% CI, 0.71 to 0.98). PSM analysis affirmed 18% reduction in prostate cancer risk associated with SGLT2i use (HR, 0.82; 95% CI, 0.67 to 0.99). Subgroup analyses revealed that body mass index (BMI) significantly influenced the effect of SGLT2i on prostate cancer risk, with a more pronounced reduction in the subgroup with a BMI <25 kg/m2 (P=0.037).
Conclusion
The use of SGLT2is in Korean male patients with T2DM is associated with a lower risk of prostate cancer.

Background
We investigated the incidence rates of hepatocellular carcinoma (HCC) in metabolic dysfunction-associated steatotic liver disease (MASLD) categories, focusing on its association with alcohol consumption in patients with type 2 diabetes mellitus (T2DM).
Methods
This study included 2,418,858 patients with T2DM aged 20 years and older who underwent a health examination between 2009 and 2012. Participants were categorized into five groups according to hepatic steatosis, cardiometabolic risk factors, other liver diseases, and alcohol consumption. Hepatic steatosis was defined as the fatty liver index ≥30. Cox regression analysis was used to analyze the association between steatotic liver disease and development of HCC.
Results
The MASLD group showed a higher risk of HCC development regardless of alcohol consumption or presence of other liver diseases (adjusted hazard ratio [aHR], 1.38; 95% confidence interval [CI], 1.33 to 1.44). The MASLD with other combined group expressed the highest risk (aHR, 5.02; 95% CI, 4.79 to 5.27). In the metabolic dysfunction and alcohol-related steatotic liver disease and alcohol-related liver disease groups, heavy to excessive alcohol consumption increased the risk of HCC development, with a higher risk associated with greater alcohol intake (aHR, 2.40; 95% CI, 2.27 to 2.53 and aHR, 3.16; 95% CI, 2.93 to 3.41). Fine and Gray analysis also exhibited a consistent trend.
Conclusion
MASLD in patients with T2DM was associated with an increased risk of developing HCC, particularly when accompanied by other liver diseases. Moreover, alcohol consumption proportionally increased the risk of HCC with the amount of alcohol consumed.
