Abstract PDF: Background
Previous research has linked solitary living to various adverse health outcomes, but its association with diabetic complications among individuals with type 2 diabetes mellitus (T2DM) remains underexplored. We examined the risk of endstage kidney disease (ESKD) in individuals with diabetes living alone (IDLA).
Methods
This population-based cohort study used the National Health Information Database of Korea, which included 2,432,613 adults with T2DM. Household status was determined based on the number of registered family members. IDLA was defined as continuously living alone for 5 years or more. A multivariable Cox proportional hazards model was used to evaluate the association between living alone and the risk of developing ESKD.
Results
During a median follow-up of 6.0 years, 26,691 participants developed ESKD, with a higher incidence observed in the IDLA group than in the non-IDLA group. After adjusting for confounding variables, the hazard ratio for ESKD in the IDLA group was 1.10 (95% confidence interval, 1.06 to 1.14). The risk of ESKD was particularly elevated in younger individuals, those without underlying chronic kidney disease, with longer durations of living alone, and with low household income. Adherence to favorable lifestyle behaviors (no smoking, no alcohol consumption, and engaging in regular exercise) was associated with a significantly lower risk of ESKD, with a more pronounced effect in the IDLA group.
Conclusion
Living alone was associated with a higher risk of ESKD in individuals with T2DM. Tailored medical interventions and social support for IDLA are crucial for the prevention of diabetic complications.

Abstract PDF: Background
The autonomic nervous system plays a crucial role in the brain’s communication with metabolically important peripheral organs, modulating insulin sensitivity and secretion. Increased sympathetic tone is a common feature in prediabetes and diabetes. The parasympathetic nervous system activity might be improvable through resonance frequency breathing (RFB) with heart rate variability biofeedback (HRV-BF) training.
Methods
We here investigated the effect of a 4-week mobile RFB-HRV-BF intervention on glucose metabolism and HRV of 30 healthy adults (17 females; mean age 25.77±3.64 years; mean body mass index 22.65±2.95 kg/m²). Before and after the intervention, glucose metabolism was assessed by 75 g oral glucose tolerance tests (with blood sampling every 30 minutes over 2 hours) and HRV was measured through electrocardiography.
Results
RFB-HRV-BF training did not influence glucose metabolism in healthy adults but reduced fasting as well as 2-hour-postload glucose in participants categorized as more insulin resistant before the intervention. In addition, RFB-HRV-BF training was associated with an increase in the time and frequency domain HRV parameters standard deviation of all NN-intervals, root mean square successive differences, HRV high-frequency and HRV low-frequency after 4 weeks of intervention.
Conclusion
Our findings introduce RFB-HRV-BF training as an effective tool to modulate the autonomic nervous system with a shift towards the parasympathetic tone. Along with the observed decrease in glycemia in those with lower insulin sensitivity, RFB-HRV-BF training emerges as a promising non-pharmacological approach to improve glucose metabolism which has to be further investigated in prediabetes and diabetes.

Diabetic retinopathy (DR) is a major cause of vision loss, linked to hyperglycemia, oxidative stress, and inflammation. Despite advancements in DR treatments, approximately 40% of patients do not respond effectively, underscoring the need for novel, noninvasive biomarkers to predict DR risk and progression. This study investigates causal relationships between specific biomarkers, dietary factors, and DR development using Mendelian randomization (MR) and cross-sectional data.
Methods
We conducted a two-phase analysis combining MR and cross-sectional methods. First, MR analysis examined causal associations between 35 biomarkers, 226 dietary factors, and DR progression using data from the UK Biobank and Genome-Wide Association Study (GWAS) datasets. Second, a cross-sectional study with National Health and Nutrition Examination Survey (NHANES) and a clinical cohort from Tianjin Medical University Eye Hospital validated findings and explored biomarkers’ predictive capabilities through a nomogram-based prediction model.
Results
MR analysis identified eight biomarkers (e.g., glycosylated hemoglobin [HbA1c], high-density lipoprotein cholesterol [HDL-C]) with significant causal links to DR. Inflammatory markers and metabolic factors, such as high glucose and HDL-C levels, were strongly associated with DR risk and progression. Specific dietary factors, like cheese intake, exhibited protective roles, while alcohol intake increased DR risk. Validation within NHANES and Tianjin cohorts supported these causal associations.
Conclusion
This study elucidates causal relationships between biomarkers, dietary habits, and DR progression, emphasizing the potential for personalized dietary interventions to prevent or manage DR. Findings support the use of HDL-C, HbA1c, and dietary factors as biomarkers or therapeutics in DR, though further studies are needed for broader applicability.

Abstract PDF Supplementary Material PubReader ePub: Background
Due to the limited availability of therapeutic agents for type 2 diabetic kidney disease (T2DKD), there is a need for further knowledge derived from experimental models and innovative techniques. In addressing this issue, single-cell RNA sequencing (scRNA-seq) has been exclusively applied to a genetically modified diabetic kidney disease model, but not to an induced model representing T2DKD. Herein, we analyzed scRNA-seq and other experiments from an induced T2DKD model and validated the results in human-derived biospecimens.
Methods
The model was induced by combining a high-fat diet with streptozotocin to simulate induced T2DKD. scRNA-seq, histological, and flow cytometric analyses were conducted, and the results were compared with control mice. The findings were then applied to human T2DKD kidneys.
Results
Biochemical and histological analyses unveiled early-stage T2DKD features, such as hyperfiltration, increased proteinuria, glomerulomegaly, and interstitial fibrosis. scRNA-seq identified that proximal tubules secreted a variety of chemokines, potentially in response to crosstalk with glomeruli. Notably, C-X-C motif chemokine 12 (CXCL12) emerged as a key player in potentially promoting T-cell recruitment. Flow cytometry substantiated T-cell infiltration into the kidney of the T2DKD model. This finding was further corroborated in human biopsied kidney tissues, showing a correlation between elevated CXCL12 levels and T2DKD progression.
Conclusion
The induced T2DKD model highlights the pivotal role of CXCL12-mediated T-cell infiltration, stemming from the crosstalk between proximal tubules and glomeruli. This data serves as a foundation for future studies, promising a therapeutic target for T2DKD.

Diabetes is associated with reduced lifespan. To explore pay-for-performance (P4P) program and life expectancy (LE), we investigated the impact of interval between diabetes diagnosis and enrollment in P4P program on loss-of-LE among patients with diabetes in Taiwan.
Methods
From diabetes mellitus health database, which collected all newly-diagnosed patients with diabetes by calendar year, we selected patients, aged 40 to 64, with 503,662 in P4P group and 450,071 in non-P4P group, respectively, from 2004 to 2015, and followed them until the end of 2018 using Kaplan–Meier survival analysis. We simulated age-, gender-, and calendar yearmatched referents for each group through Monte Carlo method from Taiwan’s vital statistics. We constructed a restricted cubic spline model on logit-transformed relative survival between each group and its corresponding matched referents, and applied a rolling-over algorithm month-by-month to extrapolate the survival function of each index group to lifetime to estimate the LE, which was subtracted from that of matched referents to obtain the loss-of-LE.
Results
We found stratified analysis by interval showed that the earlier the enrollment, the lower the loss-of-LE, namely, 0.06±0.72 years for interval <1 year, 0.05±0.59 years for interval 1–4 years, 10.01±0.11 years for interval 5–9 years, and 12.77±0.14 years for interval 10–15 years, respectively (P<0.001), compared with 2.60±0.14 years for non-P4P group.
Conclusion
Early enrollment in the P4P program was associated with reduced loss-of-LE, indicating P4P might gain life if implemented early after diabetes diagnosis.

Abstract PDF Supplementary Material PubReader ePub: Background
Studies have reported a significant association between pregravid weight gain and the subsequent development of gestational diabetes mellitus (GDM) in various populations. The current study aims to investigate this relationship using data from the Korean National Health Insurance Service database.
Methods
We conducted a retrospective nationwide population-based cohort study, involving 159,798 women who gave birth between 2015 and 2017 and had undergone two national health screening examinations: 1 year (index checkup) and 3 years before (baseline checkup) their respective estimated conception date. Participants were categorized into five groups based on the extent of weight change between the two examinations: more than 10%, 5% to 10%, –5% to 5% (reference group), –10% to –5%, and more than –10%. The study assessed the association between pregravid weight change and GDM risk.
Results
Among the 146,363 women analyzed, 11,012 (7.52%) were diagnosed with GDM. Multiple regression analysis revealed that women who gained 5% to 10% of their weight had a 12% increased risk of GDM (adjusted odds ratio [aOR], 1.12; 95% confidence interval [CI], 1.06 to 1.17), while those who gained ≥10% had a 34% higher risk (aOR, 1.34; 95% CI, 1.26 to 1.43). Notably, pregravid weight gain was particularly associated with GDM risk in non-obese or non-metabolic syndrome groups at index checkup.
Conclusion
Pregravid weight gain showed a dose-dependent association with a higher risk of GDM. This association was more pronounced in non-obese individuals emphasizing the importance of minimizing pregravid weight gain for GDM prevention, even in non-obese women.

To investigate the association of adherence to five modifiable lifestyle factors (limiting alcohol, physical activity, limiting smoking, favorable diet quality, and adequate sleep) with metabolic syndrome (MetS) risk in Korean adults.
Methods
Health Examinees Study data were used, and 41,368 participants aged 40 to 69 years were included. Cox proportional hazards regression analyses assessed the associations of individual and combined healthy lifestyle factors (32 and 16 lifestyle profiles in men and women.
Results
During a median 4.2-year follow-up, 6,213 participants were newly diagnosed with MetS. Adherence to more healthy lifestyle factors (4–5 vs. 0–1) could lower MetS risk by 28% and 12% in men and women (hazard ratio [HR], 0.72; 95% confidence interval [CI], 0.63 to 0.83 in men; HR, 0.88; 95% CI, 0.78 to 0.99 in women). Each additional healthy lifestyle could reduce the risk of MetS by 10% and 6% in men and women. The pooled analysis yielded similar results based on similar numbers of healthy lifestyle factors, the risk of MetS decreased as the number of healthy lifestyle factors increased.
Conclusion
Adherence to more healthy lifestyle factors was inversely associated with MetS risk. These findings highlight the importance of limiting drinking in managing MetS. Future research should consider the synergistic effects of emerging lifestyle factors, such as sleep duration, on chronic disease development, while focusing on the effects of traditional lifestyle factors.

The relationship between fibroblast growth factor 21 (FGF21) and sweet taste perception and preference in type 2 diabetes mellitus (T2DM) remains unclear. This study aims to investigate this relationship and examine the neural responses of T2DM patients to high-calorie sweet (HCS) food pictures, further exploring its correlation with FGF21 levels.
Methods
We assessed sweet taste perception and preference in 40 T2DM patients and 41 controls using classical scales. Subsequently, the neural responses of 11 T2DM patients and 11 controls to HCS pictures were examined using functional magnetic resonance imaging. FGF21 levels were measured using chemiluminescent immunoassay, and the correlations with taste perception and neural responses were analyzed.
Results
Increased FGF21 levels were associated with decreased sweet perception and increased sweet taste preference in T2DM patients. Compared to control, T2DM patients exhibited greater neural activations in the orbitofrontal cortex, anterior cingulate cortex (ACC), thalamus, and hippocampus (HCS vs. non-food) as well as the putamen (HCS vs. low-calorie food). Notable differences were observed in the parahippocampal gyrus, insula, ACC, and hippocampus in T2DM patients (HCS vs. high-calorie non-sweet). Additionally, FGF21 accounted for 30.39% and 32.4% of the associations between T2DM and ACC, and parahippocampal gyrus, respectively.
Conclusion
FGF21 levels were independently associated with changes in sweet taste perception and preference in T2DM patients and were significantly associated with activation in reward-related brain regions. This study reveals the potential role of FGF21 in regulating responses to sweet foods in T2DM and provides insight to develop new therapeutic strategies for diabetes.

Abstract PDF PubReader ePub: Background
The CXC motif chemokine ligand 8 (CXCL8)-CXC motif chemokine receptor 1/2 (CXCR1/2) axis has been implicated in type 1 diabetes mellitus (T1DM). Its actions on non-immune cells may also contribute to T1DM-associated complications, including painful diabetic peripheral neuropathy (DPN) and diabetic retinopathy (DR).
Methods
We assessed the efficacy of early (4–8 weeks) or late (8–12 weeks) daily ladarixin (LDX) for the treatment of streptozotocin (STZ)-induced T1DM and the related complications of DPN or DR in male rats.
Results
Early LDX mitigated STZ-induced dysmetabolism (i.e., blood glucose, insulin), inflammation in dorsal root ganglion/ sciatic nerve (interleukin-1β and tumor necrosis factor-α expression) and mechanical allodynia and thermal hyperalgesia, indicative of DPN. Moreover, vitreous citrullinated histone H3 (CitH3) and plasma GRO/CINC1 (CXCL8) increase were attenuated. Late LDX failed to reverse STZ-induced changes in metabolic parameters (i.e., blood glucose, insulin, C-peptide, pancreatic β-cell number and function). Strikingly, even in the absence of an effect on glycemic control, late LDX mitigated STZ-induced mechanical allodynia and thermal hyperalgesia and vitreous (CXCL8, CitH3) and retinal (CXCL8, CXCR1/2, myeloperoxidase, CitH3) inflammatory/pro-angiogenic (vascular endothelial growth factor, CD34) signs of DR.
Conclusion
These data confirm the efficacy of LDX in STZ-induced T1DM and provide evidence of a protective effect also against DPN and onset of DR which is independent of its effect on β-cell functionality preservation and glycemic control.

Type 2 diabetes mellitus (T2DM) is a major cause of declining renal function.
Methods
Temporal trends in T2DM-related chronic kidney disease (CKD-T2DM) incidence across 204 countries and territories from 1992 to 2021 were analyzed using data from the Global Burden of Disease 2021. The impact of macro-factors (demographic change, age, period, and birth cohort) on CKD-T2DM incidence trends was assessed using decomposition analyses and age-period- cohort modeling, highlighting opportunities to improve incidence and reduce regional disparities.
Results
In 2021, global CKD-T2DM incidence cases reached 2.01 million, a 150.92% increase since 1992, with population growth and aging contributing to 80% of this rise. The age-standardized incidence rate (ASIR) ranged from 15.09 per 100,000 in low sociodemographic index (SDI) regions to 23.07 in high SDI regions. China, India, the United States, and Japan have the most incidence cases, accounted for 69% of incidence cases globally. With 175 countries showing an increasing ASIR trend. Unfavorable trend in ASIR increase were generally found in most high-middle and middle SDI countries, such as China and Mexico (net drift=0.15% and 1.17%, per year). Age-period-cohort analyses indicated a high incidence risk near age 80, with worsening risks for recent periods and birth cohorts, except in high SDI areas.
Conclusion
The CKD-T2DM incidence burden continues to rise globally, with significant variations between countries, posing major global health implications. CKD-T2DM is largely preventable and treatable, warranting greater attention in global health policy, particularly for older populations and in low and middle SDI regions.

Abstract PDF Supplementary Material PubReader ePub: Background
Chronic low-grade inflammation in multiple metabolic organs contributes to the development of insulin resistance induced by obesity. Progranulin (PGRN) is an evolutionarily-conserved secretory protein implicated in immune modulation. The generalized deletion of the PGRN-encoded Grn gene improves insulin resistance and glucose intolerance in obese mice fed a high-fat diet (HFD). However, it remains unclear which cells or organs are responsible for the beneficial metabolic effect of Grn depletion.
Methods
Considering the critical role of macrophages in HFD-induced obesity and inflammation, we generated mice with a macrophage-specific Grn depletion (Grn-MΦKO mice) by mating lysozyme M (LysM)-Cre and Grn-floxed mice. Body weight, food intake, energy expenditure, and glucose and insulin tolerance were compared between Grn-MΦKO mice and their wildtype (WT) controls under normal chow diet (NCD)- or HFD-fed conditions. We also examined macrophage activation and inflammation- related gene expression in the visceral adipose tissue and hypothalamus along with insulin and leptin signaling.
Results
Grn-MΦKO mice showed no alteration in metabolic phenotypes under NCD-fed conditions. However, upon HFD feeding, these mice exhibited less weight gain and improved glucose and insulin tolerance compared to WT mice. Moreover, HFD-induced macrophage activation and proinflammatory cytokine expression were significantly reduced in both the adipose tissue and hypothalamus of Grn-MΦKO mice, while HFD-induced impairments in leptin and insulin signaling showed improvement.
Conclusion
Macrophage-derived PGRN and possibly other Grn products play a critical role in the development of HFD-induced obesity, tissue inflammation, and impaired hormonal signaling in both central and peripheral metabolic organs.

Type 1 diabetes mellitus related chronic kidney disease (T1DM-CKD) presents a global health challenge, with unclear trends and patterns among adolescents and young adults. This study analyzed the burden and risk factors of T1DM-CKD in individuals aged 15 to 39 from 1990 to 2021 and predicted future trends.
Methods
Using data from the Global Burden of Disease (GBD) study 2021, we analyzed the prevalence, incidence, mortality, disability-adjusted life years (DALYs), and average annual percentage change (AAPC) of T1DM-CKD among youth across gender, sociodemographic index (SDI) areas, and data from 21 regions and 204 countries and territories. Risk factors were assessed and future trends were projected.
Results
Between 1990 and 2021, the global prevalence of T1DM-CKD aged 15 to 39 increased by 107.5% to 3.32 million, with an age-standardized prevalence rate (ASPR) of 111.44 per 100,000 (AAPC 1.33%). Incidence rose by 165.4% to 14,200, with an agestandardized incidence rate of 0.48 per 100,000 (AAPC 2.19%). However, age-standardized mortality rate (0.50 per 100,000, AAPC –0.87%) and age-standardized DALYs rate (30.61 per 100,000, AAPC –0.83%) decreased. ASPR increased across all SDI regions, especially in high-SDI countries. High fasting glucose remained the major risk factor influencing DALYs. By 2035, T1DM-CKD prevalence was projected to decrease to 2.86 million (ASPR 89.67 per 100,000).
Conclusion
The research revealed a global increase in T1DM-CKD among youth, with a shift towards younger onset and significant variations based on gender and location, emphasizing the importance of early prevention and management strategies for this demographic.

Abstract PDF PubReader ePub: Background
Patients with diabetes are known to be at high risk for end-stage kidney disease (ESKD), but the accurate annual risk data for new-onset ESKD is still limited. In South Korea, the prevalence and incidence of ESKD are increasing more rapidly compared to the global average. This study aimed to determine the incidence rate (IR) of ESKD by diabetes status from 2012 to 2022.
Methods
Using data from the Korean National Health Insurance Service, we calculated the IR and hazard ratio (HR) for newonset ESKD in the general population. Individuals were categorized based on diabetes status into nondiabetes, impaired fasting glucose (IFG), diabetes duration <5 and ≥5 years.
Results
Among the participants, 67.6% were nondiabetic, 22.3% had IFG, and 10% had diabetes. In Korea, the IRs of ESKD were 139 per million population (pmp) for nondiabetes, 188 pmp for IFG, 632 pmp for diabetes <5 years, and 3,403 pmp for diabetes ≥5 years. An advanced estimated glomerular filtration rate (eGFR) category was the strongest risk factor for ESKD development. However, even in patients with normal renal function, those with long-standing diabetes had a 14-fold higher risk of ESKD compared to nondiabetic individuals. The risk of ESKD associated with diabetes increased exponentially with declining renal function. Notably, IFG showed an increasing tendency for ESKD in younger patients (<65 years) with early-stage chronic kidney disease (CKD; eGFR ≥60 mL/min/1.73 m²).
Conclusion
Longer diabetes duration amplifies ESKD risk, particularly as renal function declines. Even in patients with normal renal function, long-standing diabetes significantly increases ESKD risk, while IFG is associated with elevated risk only in younger individuals with early-stage CKD.
