Abstract
Background It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia. Methods This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and <10.0%, low-density lipoprotein cholesterol (LDL-C) >100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment. Results After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. -0.58%, respectively; P<0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P<0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (-55.20% vs. -7.69%, P<0.001) without previously unknown adverse drug events. Conclusion The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin's preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose.

Abstract
AIMS/HYPOTHESIS This study compares the efficacy and safety of a tubeless, on-body automated insulin delivery (AID) system with that of a tubeless, on-body sensor-augmented pump (SAP). METHODS This multicentre, parallel-group, RCT was conducted at 13 tertiary medical centres in South Korea. Adults aged 19-69 years with type 1 diabetes who had HbA1c levels of <85.8 mmol/mol (<10.0%) were eligible. The participants were assigned at a 1:1 ratio to receive a tubeless, on-body AID system (intervention group) or a tubeless, on-body SAP (control group) for 12 weeks. Stratified block randomisation was conducted by an independent statistician. Blinding was not possible due to the nature of the intervention. The primary outcome was the percentage of time in range (TIR), blood glucose between 3.9 and 10.0 mmol/l, as measured by continuous glucose monitoring. ANCOVAs were conducted with baseline values and study centres as covariates. RESULTS A total of 104 participants underwent randomisation, with 53 in the intervention group and 51 in the control group. The mean (±SD) age of the participants was 40±11 years. The mean (±SD) TIR increased from 62.1±17.1% at baseline to 71.5±10.7% over the 12 week trial period in the intervention group and from 64.7±17.0% to 66.9±15.0% in the control group (difference between the adjusted means: 6.5% [95% CI 3.6%, 9.4%], p<0.001). Time below range, time above range, CV and mean glucose levels were also significantly better in the intervention group compared with the control group. HbA1c decreased from 50.9±9.9 mmol/mol (6.8±0.9%) at baseline to 45.9±7.4 mmol/mol (6.4±0.7%) after 12 weeks in the intervention group and from 48.7±9.1 mmol/mol (6.6±0.8%) to 45.7±7.5 mmol/mol (6.3±0.7%) in the control group (difference between the adjusted means: -0.7 mmol/mol [95% CI -2.0, 0.8 mmol/mol] (-0.1% [95% CI -0.2%, 0.1%]), p=0.366). No diabetic ketoacidosis or severe hypoglycaemia events occurred in either group. CONCLUSIONS/INTERPRETATION The use of a tubeless, on-body AID system was safe and associated with superior glycaemic profiles, including TIR, time below range, time above range and CV, than the use of a tubeless, on-body SAP. TRIAL REGISTRATION Clinical Research Information Service (CRIS) KCT0008398 FUNDING: The study was funded by a grant from the Korea Medical Device Development Fund supported by the Ministry of Science and ICT; the Ministry of Trade, Industry and Energy; the Ministry of Health and Welfare; and the Ministry of Food and Drug Safety (grant number: RS-2020-KD000056).

Abstract
AIMS In this study, we aimed to evaluate the impact of overall cardiovascular disease (CVD) risk on the development of incident T2DM in patients with prediabetes. METHODS We retrospectively enrolled 5,908 subjects with prediabetes who underwent health check-ups at the Asan Medical Center. CVD risk was estimated using the Framingham Risk Score (FRS). We compared moderate- to high-risk groups with low-risk controls based on the FRS. Cox proportional hazards regressions were conducted to estimate the time-to-develop incident T2DM. RESULTS Among the 5908 subjects with prediabetes, 3031 (51.8 %) were identified to have either moderate or high CVD risk scores. During a median follow-up of 5.2 years, 278 (9.2 %) patients from the moderate- to high-risk group and 171 (5.9 %) from the low-risk group were diagnosed with T2DM. The covariate-adjusted hazard ratio for the incident T2DM was 1.30 (95 % CI, 1.06-1.60, p = 0.011) in the moderate- to high-risk group compared to the low-risk controls. CONCLUSION Among patients with prediabetes, those with high CVD risk were more likely to develop incident T2DM, as determined by the FRS. CVD risk factors should be properly evaluated and managed in individuals with prediabetes to reduce the risk of both incident T2DM and associated cardiovascular complications.

Abstract
CONTEXT Ectopic fat deposition in skeletal muscle, termed myosteatosis, is a key factor in developing insulin resistance. OBJECTIVE This work aimed to evaluate the association between insulin resistance and myosteatosis in a large Asian population. METHODS A total of 18 251 participants who had abdominal computed tomography were included in this cross-sectional study. Patients were categorized into 4 groups according to quartiles of Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). The total abdominal muscle area (TAMA) at the L3 vertebral level was segmented into normal-attenuation muscle area (NAMA), low-attenuation muscle area (LAMA), and intermuscular adipose tissue (IMAT). The absolute values of TAMA, NAMA, LAMA, and IMAT and the ratios of NAMA/BMI, LAMA/BMI, and NAMA/TAMA were used as myosteatosis indices. RESULTS The absolute values of TAMA, NAMA, LAMA, and IMAT appeared to increase with higher HOMA-IR levels, and LAMA/BMI showed a similar upward trend. Meanwhile, the NAMA/BMI and NAMA/TAMA index showed downward trends. As HOMA-IR levels increased, the odds ratios (ORs) of the highest quartile of NAMA/BMI and NAMA/TAMA index decreased and that of LAMA/BMI increased. Compared with the lowest HOMA-IR group, the adjusted ORs (95% CI) in the highest HOMA-IR group for the lowest NAMA/TAMA quartile were 0.414 (0.364-0.471) in men and 0.464 (0.384-0.562) in women. HOMA-IR showed a negative correlation with NAMA/BMI (r = -0.233 for men and r = -0.265 for women), and NAMA/TAMA index (r = -0.211 for men and r = -0.214 for women), and a positive correlation with LAMA/BMI (r = 0.160 for men and r = 0.119 for women); P was less than .001 for all. CONCLUSION In this study, a higher HOMA-IR level was significantly associated with a high risk of myosteatosis.

Abstract
BACKGROUND Contrary to the previously known concept of muscle mass decrease following bariatric metabolic surgery, changes in muscle strength have been poorly investigated in systematic reviews. In this meta-analysis, we evaluated changes in handgrip strength (HGS) and lean mass (LM) after undergoing bariatric metabolic surgery. METHODS A systematic literature review using the PubMed, Embase, and Cochrane Library databases was conducted in November 2022. Longitudinal studies reporting HGS change after bariatric metabolic surgery were eligible. Pooled estimates for changes in HGS, body mass index (BMI), LM, and fat mass (FM) were calculated. Changes from baseline to the point closest to 6 months postoperatively were analyzed in trials with multiple follow-up examinations. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist. RESULTS Three randomized controlled trials and seven prospective cohort studies involving 301 patients were included. Follow-up evaluations were conducted 6 months postoperatively in all trials except for two, whose follow-up visits were at 18 weeks and 12 months, respectively. Pooled analysis showed reduced BMI (- 10.8 kg/m2; 95% confidence interval: - 11.6 to - 9.9 kg/m2), LM (- 7.4 kg; - 9.3 to - 5.4 kg), and FM (- 22.3 kg; - 25.1 to - 19.6 kg) after bariatric metabolic surgery, whereas the change in HGS was not statistically significant (- 0.46 kg; - 1.76 to 0.84 kg). CONCLUSION Despite the decreased body composition parameters, including muscle mass, strength was not impaired after bariatric metabolic surgery; this indicates that bariatric metabolic surgery is an effective weight management intervention that does not compromise strength.

Abstract
With the increasing use of immune-checkpoint inhibitors (ICIs), such as anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and anti-programmed cell death-1 (PD-1), for the treatment of malignancies, cases of ICI-induced type 1 diabetes mellitus (ICI-T1DM) have been reported globally. This review focuses on the features and pathogenesis of this disease. T1DM is an immune-related adverse event that occurs following the administration of anti-PD-1 or anti-programmed death ligand-1 (PDL1) alone or in combination with anti-CTLA-4. More than half of the reported cases presented as abrupt-onset diabetic ketoacidosis. The primary mechanism of ICI-T1DM is T-cell stimulation, which results from the loss of interaction between PD-1 and PD-L1 in pancreatic islet. The similarities and differences between ICI-T1DM and classical T1DM may provide insights into this disease entity. ICI-T1DM is a rare but often life-threatening medical emergency that healthcare professionals and patients need to be aware of. Early detection of and screening for this disease is imperative. At present, the only known treatment for ICI-T1DM is insulin injection. Further research into the mechanisms and risk factors associated with ICI-T1DM development may contribute to a better understanding of this disease entity and the identification of possible preventive strategies.

Abstract
BACKGROUND/AIMS To investigate whether non-alcoholic fatty liver disease (NAFLD) in individuals without generalized obesity is associated with visceral fat obesity (VFO), sarcopenia, and/or myosteatosis. METHODS This cross-sectional analysis included 14,400 individuals (7,470 men) who underwent abdominal computed tomography scans during routine health examinations. The total abdominal muscle area (TAMA) and skeletal muscle area (SMA) at the 3rd lumbar vertebral level were measured. The SMA was divided into the normal attenuation muscle area (NAMA) and low attenuation muscle area, and the NAMA/TAMA index was calculated. VFO was defined by visceral to subcutaneous fat ratio, sarcopenia by body mass index-adjusted SMA, and myosteatosis by the NAMA/TAMA index. NAFLD was diagnosed with ultrasonography. RESULTS Of the 14,400 individuals, 4,748 (33.0%) had NAFLD, and the prevalence of NAFLD among non-obese individuals was 21.4%. In regression analysis, both sarcopenia (men: odds ratio [OR] 1.41, 95% confidence interval [CI] 1.19-1.67, P<0.001; women: OR=1.59, 95% CI 1.40-1.90, P<0.001) and myosteatosis (men: OR=1.24, 95% CI 1.02-1.50, P=0,028; women: OR=1.23, 95% CI 1.04-1.46, P=0.017) were significantly associated with non-obese NAFLD after considering for VFO and other various risk factors, whereas VFO (men: OR=3.97, 95% CI 3.43-4.59 [adjusted for sarcopenia], OR 3.98, 95% CI 3.44-4.60 [adjusted for myosteatosis]; women: OR=5.42, 95% CI 4.53-6.42 [adjusted for sarcopenia], OR=5.33, 95% CI 4.51-6.31 [adjusted for myosteatosis]; all P<0.001) was strongly associated with non-obese NAFLD after adjustment with various known risk factors. CONCLUSION In addition to VFO, sarcopenia and/or myosteatosis were significantly associated with non-obese NAFLD.

Abstract
Glucagon-like peptide-1 (GLP-1) receptor agonists have been used extensively in the clinic and have an established safety profile in cardiovascular disease settings. For the treatment of peptide-secreting enteroendocrine cells, most research has focused on developing peptide multi-agonists as most of these cells are multihormonal. Among the various peptides secreted by enteroendocrine cells, the combination of GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) is an attractive strategy for treating type 2 diabetes mellitus (T2DM) because both of these hormones have glucose-lowering actions. Tirzepatide, a synthetic peptide composed of 39 amino acids, functions as a dual receptor agonist of both the GIP and GLP-1 receptors. This unique mechanism of action has earned tirzepatide the nickname "twincretin." Tirzepatide's dual agonist activity may be the mechanism by which tirzepatide significantly reduces glycated hemoglobin levels and body weight in patients with T2DM as observed in phase 3 clinical trials. Besides its glucose-lowering and anti-obesity effects, tirzepatide has been reported to have potential cardiovascular benefits. In this review, we discuss the cardiovascular effects of tirzepatide based on the available preclinical and clinical data.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is common and is associated with cardiovascular (CV) disease and mortality. The Framingham steatosis index (FSI) was recently proposed as a diagnostic marker of NAFLD and was calculated from age, body mass index, triglyceride, aspartate aminotransferase, alanine aminotransferase, diabetes history, and hypertension status. We aimed to evaluate the predictive ability of FSI for CV risk using a large-scale population dataset from the Korean National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS). Methods Among 514,866 individuals in the NHIS-HEALS, we excluded those who died, had a history of admission due to a CV event, and were heavy drinkers. The final study cohort comprised 283,427 participants. We employed both unadjusted and covariate-adjusted models in Cox proportional hazards regression analyses to determine the association between FSI and major adverse cardiovascular events (MACEs), CV events, and CV mortality. Results During a median follow-up of 5.9 years, we documented 9,674, 8,798, and 1,602 cases of MACEs, CV events, and CV mortality, respectively. The incidence of MACEs was 1.28%, 2.99%, 3.94%, and 4.82% in the first to fourth quartiles of FSI, respectively. The adjusted hazard ratios (95% confidence interval) for MACEs gradually and significantly increased with the FSI quartiles [1.302 (1.215-1.395) in Q2, 1.487 (1.390-1.590) in Q3, and 1.792 (1.680-1.911) in Q4], following an adjustment for conventional CV risk factors, including age, sex, smoking, drinking, physical activities, low-density lipoprotein cholesterol, estimated glomerular filtration rate, and waist circumference. Participants in the higher quartiles of FSI exhibited a noteworthy increase in the occurrence of CV event. However, upon adjusting for relevant risk factors, the association between FSI and CV mortality did not reach statistical significance. Conclusion Our study suggests that the FSI, which is a surrogate marker of NAFLD, has a prognostic value for detecting individuals at higher risk of CV events.

Abstract
Background The association between body mass index (BMI) and mortality in patients with type 1 diabetes mellitus (T1DM) has been poorly examined and has never been systematically reviewed. This meta-analysis investigated the all-cause mortality risk for each BMI category among patients with T1DM. Methods A systematic literature review of the PubMed, Embase, and Cochrane Library databases was performed in July 2022. Cohort studies comparing the mortality risk between BMI categories among patients with T1DM were eligible. Pooled hazard ratios (HRs) for all-cause mortality among underweight (BMI <18.5 kg/m2), overweight (BMI, 25 to <30 kg/m2), and obese (BMI ≥30 kg/m2) individuals were calculated in reference to the normal-weight group (BMI, 18.5 to <25 kg/m2). The Newcastle-Ottawa Scale was used to assess the risk of bias. Results Three prospective studies involving 23,407 adults were included. The underweight group was shown to have a 3.4 times greater risk of mortality than the normal-weight group (95% confidence interval [CI], 1.67 to 6.85). Meanwhile, there was no significant difference in mortality risk between the normal-weight group and the overweight group (HR, 0.90; 95% CI, 0.66 to 1.22) or the obese group (HR, 1.36; 95% CI, 0.86 to 2.15), possibly due to the heterogeneous results of these BMI categories among the included studies. Conclusion Underweight patients with T1DM had a significantly greater risk of all-cause mortality than their normal-weight counterparts. Overweight and obese patients showed heterogeneous risks across the studies. Further prospective studies on patients with T1DM are required to establish weight management guidelines.

Abstract
OBJECTIVE This study evaluated whether sarcopenic obesity is closely associated with muscle quality using abdominal computed tomography. METHODS This cross-sectional study included 13,612 participants who underwent abdominal computed tomography. The cross-sectional area of the skeletal muscle was measured at the L3 level (total abdominal muscle area [TAMA]) and segmented into normal attenuation muscle area (NAMA, +30 to +150 Hounsfield units), low attenuation muscle area (-29 to +29 Hounsfield units), and intramuscular adipose tissue (-190 to -30 Hounsfield units). The NAMA/TAMA index was calculated by dividing NAMA by TAMA and multiplying by 100, and the lowest quartile of NAMA/TAMA index was defined as myosteatosis (<73.56 in men and <66.97 in women). Sarcopenia was defined using BMI-adjusted appendicular skeletal muscle mass. RESULTS The prevalence of myosteatosis was found to be significantly higher in participants with sarcopenic obesity (17.9% vs. 54.2%, p < 0.001) than the control group without sarcopenia or obesity. Compared with the control group, the odds ratio (95% CI) for having myosteatosis was 3.70 (2.87-4.76) for participants with sarcopenic obesity after adjusting for age, sex, smoking, drinking, exercise, hypertension, diabetes, low-density lipoprotein cholesterol, and high-sensitivity C-reactive protein. CONCLUSIONS Sarcopenic obesity is significantly associated with myosteatosis, which is representative of poor muscle quality.

Abstract
Recent research has revealed causes other than aging that may induce sarcopenia in young people, contrary to the long-studied age-dependent reduction in muscular mass and function. The risk of sarcopenia begins in early adulthood, resulting in exaggerated muscle dysfunction in later life. Despite its clinical significance, research on youth-onset sarcopenia is still in its infancy. Due to a paucity of epidemiologic data and standardized criteria for sarcopenia in youth, determining the prevalence of sarcopenia in the young population remains challenging. Based on the evidence, >1 in every 10 young adults of most ethnicities is estimated to have sarcopenia. This review summarizes the possible etiologies of sarcopenia in young populations, including metabolic syndrome, physical inactivity, inadequate nutrition, inherent and perinatal factors, vitamin D deficiency, endocrinopathy, an imbalance of gut microbiota, neuromuscular diseases, organ failure, malignancy, and other inflammatory disorders. This is the first review of the current knowledge on the importance, prevalence, diagnosis, and causes of sarcopenia in youth.

Abstract
We aimed to investigate whether type 2 diabetes mellitus (T2DM) and diabetes-related complications constitute significant risk factors for nontuberculous mycobacterial (NTM) disease. Data from the National Health Insurance Service-National Sample Cohort (which represents 2.2% of the total South Korean population) recorded between 2007 and 2019 were extracted to establish the NTM-naive T2DM cohort (n = 191,218) and the 1:1 age- and sex-matched NTM-naive matched cohort (n = 191,218). Intergroup comparisons were performed to determine differences in the NTM disease risk of the two cohorts during the follow-up period. During median follow-up of 9.46 and 9.25 years, the incidence of NTM disease was 43.58/100,000 and 32.98/100,000 person-years in the NTM-naive T2DM and NTM-naive matched cohorts, respectively. Multivariable analysis showed that T2DM alone did not confer a significant risk for incident NTM disease, although T2DM with ≥2 diabetes-related complications significantly increased NTM disease risk (adjusted hazard ratio [95% confidence interval], 1.12 [0.99 to 1.27] and 1.33 [1.03 to 1.17], respectively). In conclusion, the presence of T2DM with ≥2 diabetes-related complications significantly increases the risk for NTM disease. IMPORTANCE We assessed whether patients with T2DM are at higher risk for incident NTM disease through analysis of NTM-naive matched cohorts from the data of a national population-based cohort which represents 2.2% of the total South Korean population. Although T2DM alone is not a statistically significant risk factor for NTM disease, T2DM significantly increases the risk of NTM disease in those with ≥2 diabetes-related complications. This finding suggested that patients with T2DM with a larger number of complications should be considered a high-risk group for NTM disease.

Abstract
BACKGROUND The association of myosteatosis measured using visual muscular quality map in computed tomography (CT) with nonalcoholic fatty liver disease (NAFLD), its severity, and fibrosis was analyzed in a large population. METHODS Subjects (n=13,452) with abdominal CT between 2012 and 2013 were measured total abdominal muscle area (TAMA) at L3 level. TAMA was segmented into intramuscular adipose tissue and skeletal muscle area (SMA), which was further classified into normal attenuation muscle area (NAMA) and low attenuation muscle area (LAMA). The following variables were adopted as indicators of myosteatosis: SMA/body mass index (BMI), NAMA/BMI, NAMA/TAMA, and LAMA/BMI. NAFLD and its severity were assessed by ultrasonography, and liver fibrosis was measured by calculating the NAFLD fibrosis score (NFS) and fibrosis-4 index (FIB-4) scores. RESULTS According to multiple logistic regression analyses, as quartiles of SMA/BMI, NAMA/BMI, and NAMA/TAMA increased, the odds ratios (ORs) for NAFLD decreased in each sex (P for trend <0.001 for all). The ORs of moderate/severe NAFLD were significantly higher in the Q1 group than in the Q4 group for SMA/BMI, NAMA/BMI, and NAMA/TAMA in men. The ORs of intermediate/high liver fibrosis scores assessed by NFS and FIB-4 scores increased linearly with decreasing quartiles for SMA/BMI, NAMA/BMI, and NAMA/TAMA in each sex (P for trend <0.001 for all). Conversely, the risk for NAFLD and fibrosis were positively associated with LAMA/BMI quartiles in each sex (P for trend <0.001 for all). CONCLUSION A higher proportion of good quality muscle was associated with lower risks of NAFLD and fibrosis.

Abstract
C1q/tumor necrosis factor-related protein 9 (CTRP9) is an adipokine and has high potential as a therapeutic target. However, the role of CTRP9 in cardiovascular disease pathogenesis remains unclear. We found CTRP9 to induce HDAC7 and p38 MAPK phosphorylation via tight regulation of AMPK in vascular endothelial cells, leading to angiogenesis through increased MEF2 activity. The expression of CTRP9 and atheroprotective MEF2 was decreased in plaque tissue of atherosclerotic patients and the ventricle of post-infarction mice. CTRP9 treatment inhibited the formation of atherosclerotic plaques in ApoE KO and CTRP9 KO mice. In addition, CTRP9 induced significant ischemic injury prevention in the post-MI mice. Clinically, serum CTRP9 levels were reduced in patients with MI compared with healthy controls. In summary, CTRP9 induces a vasoprotective response via the AMPK/HDAC7/p38 MAPK pathway in vascular endothelial cells, whereas its absence can contribute to atherosclerosis and MI. Hence, CTRP9 may represent a valuable therapeutic target and biomarker in cardiovascular diseases.

Abstract
Abstract
Background
No completed randomized trial exclusively incorporating the elderly has addressed the benefit of statin treatment for primary prevention until now. Therefore, consensus of major international lipid management guidelines has not been made upon lowering LDL cholesterol (LDL-C)to prevent primary atherosclerotic cardiovascular disease (ASCVD)in the older population. Question: This study aimed to investigate whether ASCVD risk according to increasing LDL-C differs between age groups.
Methods
Data was provided by the Health Screening Cohort of the Korean National Health Insurance Service, which is a nationwide health screening program covering the whole population with alow attrition rate. Subjects with preexisting cardiovascular disease or taking lipid-lowering drugs were excluded. Participants were followed up from January1,2011 to December31, 2015. Multivariable Cox proportional hazard regressions were performed to evaluate the relationship between LDL-C and ASCVD. Subgroup analyses were also conducted in patients with T2DM.
Results
The final cohort was composed of 285,119 participants with a mean age of 58.4 years and 55.2% of men. The average baseline LDL-C level was 121.5 mg/dL (standard deviation, 36.4). The proportion of individuals was 2.4% (n =6,718),9. 0% (n = 25,687), 26.6% (n = 75,981), 37.2% (n = 105,952), 20.2% (n = 57,562), and 4.6% (n = 13,219) in LDL-C ≥190, 160–189, 130–159, 100–129, 70–99, and<70 mg/dL, respectively. Patients with T2DM comprised 7.5% (n = 21,258) of the entire population. During a median follow-up of 6.44 years, the first ASCVD developed in8,996 participants (3.2%). All age groups showed positive associations between LDL-C and ASCVD risk, mostly with statistical significance from LDL-C of 160 mg/dL onward. ASCVD risk did not differ significantly between the age groups (P for interaction =0.62). Compared with ASCVD risk in LDL-C of 70–99 mg/dL, the risk in the highest LDL-C(≥190 mg/dL)was similar between groupsaged<50 and ≥70 years (adjusted hazard ratio [aHR], 1.90 [95%confidence interval (CI),1.52–2.38] and aHR, 1.86 [95% CI, 1.30–2.68], respectively). Subgroup analysis in patients with T2DM showed that 7.2% of subjects experienced incident ASCVD. Age-specific association of ASCVD risk and LDL-C in T2DM patients displayed no difference in line with the total participants(P for interaction = 0.31).
Conclusions
A large-scale, population-based cohort study of adults who had no previous CVD history and were not prescribed lipid-lowering drugs demonstrated that elevated LDL-C was significantly correlated with a greater risk of ASCVD in people aged≥70 years, which was comparable with the risk in younger adults. This finding spotlights the necessity of settling intensive guidance on LDL-C levels for primary CVD prevention in the elderly.

Abstract
The increasing prevalence of obesity is a worldwide health concern. Although obesity primarily affects the development of cardiometabolic disorders, it has also been closely linked to chronic kidney disease (CKD). However, potential causal relationships between obesity and CKD remain unclear, as obesity and CKD share a number of common risk factors. Accordingly, the risk of incident CKD in obese people without metabolic abnormalities, also called “metabolically healthy obesity” (MHO), has been a matter of interest. Recent investigations found that MHO was related to increased risk of incident CKD; however, the conclusions were based primarily on the static state. According to previous publications, approximately one-half of people initially identified as MHO became metabolically unhealthy, while one-tenth reduced their body weight to normal range while remaining metabolically healthy. It is essential to consider these transitions in obese-metabolic health status when analyzing obesity-related outcomes. This review discusses research on obesity and metabolic health in patients with CKD. Furthermore, we summarize recent reports on the implications of obesity and metabolic health in CKD and discuss the possible mechanisms of their relationship with CKD.

Abstract
Background: Obesity and obesity-related comorbidities are increasingly being recognized as significant threats to global health. Pharmacological treatments are required in patients in whom lifestyle modifications fail to achieve an individual’s target body weight.Current Concepts: Currently available short-term anti-obesity drugs, including phentermine, diethylpropion, and mazindol (all sympathetic nerve agents) serve as appetite suppressants. Prescription anti-obesity drugs currently approved for long-term use in Korea include orlistat, phentermine/topiramate, naltrexone/bupropion, and liraglutide. Semaglutide (2.4 mg) has recently been authorized by the United States Food and Drug Administration for treatment of obesity. Research is underway to introduce novel drugs that are likely to revolutionize the global anti-obesity drug market. Representative examples include tirzepatide, a dual agonist of glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide and cagrilintide, an amylin analogue. These drugs have shown excellent weight-loss effects with tolerable adverse effects in phase II or III clinical trials, with significantly greater effectiveness than that of currently available medications.Discussion and Conclusion: Despite the introduction of a variety of anti-obesity drugs, these agents are not currently widely used in all patients with obesity owing to high costs, adverse effects, and unsatisfactory effectiveness. Further research is warranted to determine the effects and adverse effects of combinations of available drugs, including tirzepatide and cagrilintide, along with the development of newer agents that may show a different mechanism of action.

Abstract
While endocrine disruptors are emerging as a cause of nonalcoholic fatty liver disease (NAFLD), little is known about the link between NAFLD and organochlorine pesticides (OCPs), one of the endocrine disruptors. We retrospectively analyzed the U.S. National Health and Nutrition Examination Survey 2003-2004 and compared the baseline demographics in individuals according to the presence of NAFLD (fatty liver index [FLI] ≥ 60). Logistic regression analysis was performed to determine whether OCP concentration affected NAFLD prevalence and subgroup analyses regarding NAFLD-related variables and advanced hepatic fibrosis (FIB-4 ≥ 2.67) were performed. Of the 1515 individuals, 579 (38.2%) had NAFLD. Oxychlordane showed concentration-dependent risk for NAFLD (OR 3.471 in fourth quartile [Q4]; 95% CI 1.865-6.458; P = 0.007). p,p'-DDE and trans-nonachlor showed similar trends without statistical significance. Conversely, mirex showed the lowest risk for NAFLD in the highest concentration quartile (OR 0.29 in Q4; 95% CI 0.175-0.483; P < 0.001). Oxychlordane showed the most pronounced association with the levels of each component of FLI and liver enzymes. None of the OCPs were significantly associated with advanced fibrosis. In conclusion, among OCPs, exposure to oxychlordane showed the most prominent impact associated with NAFLD.

Abstract
Sodium-glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1RA) are novel anti-diabetic drugs whose glucose-lowering effect and cardiovascular and renal benefits were evidenced in clinical trials. We investigated the real-world efficacy and safety of the combination of SGLT2i and GLP-1RA in patients with type 2 diabetes mellitus in Korea. The medical records of 104 patients who maintained the combination for at least 1 year were retrospectively reviewed. The change in glycosylated hemoglobin (HbA1c) after 6 months and 1 year of treatment was evaluated. The mean age was 51 years, and 41% were female. The mean baseline HbA1c, body mass index, and duration of diabetes were 9.0%, 28.8 kg/m2, and 11.7 years, respectively. Compared with baseline, the HbA1c decreased by 1.5% (95% confidence interval [CI], 1.27 to 1.74; P<0.001) after 6 months and by 1.4% (95% CI, 1.19 to 1.70; P<0.001) after 1 year. Over 1 year, the bodyweight change was -2.8 kg (95% CI, -4.21 to -1.47; P<0.001). The combination of SGLT2i and GLP-1RA is effective and tolerable in type 2 diabetes mellitus patients in real-world practice.

Abstract
Background This study assesses the prognostic value of the triglyceride–glucose (TyG) index for cardiovascular (CV) risk in subgroups based on metabolic health and obesity status. Methods Originally, 514,866 participants were enrolled from the Korean National Health Insurance Service-National Health Screening Cohort. The study participants were categorized into four groups: metabolically healthy non-obese (MHNO), metabolically unhealthy non-obese (MUNO), metabolically healthy obese (MHO), and metabolically unhealthy obese (MUO). The TyG index was calculated using the following formula: ln (fasting triglyceride [mg/dL]×fasting plasma glucose [mg/dL]/2). Participants were followed from 2009 to 2015 for CV events and CV mortality according to the TyG index. Results After exclusions, the final study cohort contained 292,206 people. During the follow-up, 9,138 CV events and 1,163 CV deaths were documented. When the high and low TyG groups were compared, the high TyG group had a substantially increased risk of CV events among the MUNO and MUO participants (multivariable-adjusted hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.07–1.30 and 1.27 [1.14–1.42], respectively). In participants with MUO status, CV mortality was also significantly increased in the high TyG group compared with the corresponding low TyG group (multivariable-adjusted HR, 1.48; 95% CI, 1.13–1.93). In contrast, a high TyG index was not related to CV mortality in the MHNO, MHO, and MUNO groups. Conclusion The predictive value of the TyG index can vary across populations. Among MUO participants, the TyG index was significantly and positively correlated with unfavorable CV outcomes.

Abstract
Background The atherogenic index of plasma (AIP) is composed of triglycerides and high-density lipoprotein cholesterol and is a novel marker for assessing the risk of atherogenicity and cardiometabolic health. An association between AIP and greater frequency of major adverse cardiovascular events (MACEs) in patients with type 2 diabetes mellitus and high cardiovascular (CV) disease risk has been reported. However, only few studies have examined the correlation between AIP and CV risk in general populations. We thus aimed to evaluate the relationship between AIP and CV diseases using a large-scale population dataset from the Korean National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS). Methods A total of 514,866 participants were enrolled from the NHIS-HEALS and classified according to the AIP quartiles. We performed univariate and multivariate Cox proportional hazards regression analyses to determine the association between AIP and MACEs, CV events, and CV mortality. Results During follow-up, we documented 12,133, 11,055, and 1942 cases of MACEs, CV events, and CV mortality, respectively. The multivariate-adjusted hazard ratios [HRs; 95% confidence interval (CI)] for MACEs gradually and significantly increased with the AIP quartiles [1.113 (1.054–1.175) in Q2, 1.175 (1.113–1.240) in Q3, and 1.278 (1.209–1.350) in Q4], following an adjustment for the conventional CV risk factors, including age, sex, body mass index, smoking, alcohol drinking, physical activities, household income, fasting glucose, systolic blood pressure, low-density lipoprotein cholesterol, and estimated glomerular filtration rate. In subgroup analyses, the association of AIP with MACEs and CV events was particularly outstanding in patients with diabetes. Conclusions AIP was significantly associated with CV risks after adjusting for the traditional risk factors. Therefore, it may be used as an effective mass screening method to identify patients at a high risk of CV events.

Abstract
Background The relationship between low‐density lipoprotein cholesterol (LDL‐C) and atherosclerotic cardiovascular disease (ASCVD) according to age remains undetermined. Thus, this study aimed to investigate the age‐related association of LDL‐C and ASCVD. Methods and Results Data from the Korean NHIS‐HEALS (National Health Insurance Service‐National Health Screening Cohort) were analyzed. Individuals previously diagnosed with cardiovascular disease or taking lipid‐lowering drugs were excluded. Age‐specific association between LDL‐C and ASCVD was calculated using adjusted Cox proportional hazards models. During a median follow‐up of 6.44 years for 285 119 adults, ASCVD developed in 8996 (3.2%). All age groups showed positive associations between LDL‐C and ASCVD risk, mostly with statistical significance from LDL‐C of 160 mg/dL onward. ASCVD risk did not differ significantly between the age groups (P for interaction=0.489). Correspondingly, subgroup analysis in type 2 diabetes exhibited no difference in the age‐specific association of LDL‐C and ASCVD (P for interaction=0.784). Conclusions The study demonstrated that people aged ≥75 years with higher LDL‐C at baseline still presented increased ASCVD risk, which was not significantly different from the younger groups. These findings support the importance of managing LDL‐C for the prevention of primary ASCVD in the growing elderly population.

Abstract
BACKGROUND This study aimed to determine the optimal cut-off values of visceral fat area (VFA) and visceral-to-subcutaneous fat ratio (VSR) for predicting incident type 2 diabetes mellitus (T2DM). METHODS A total of 10,882 individuals (6,835 men; 4,047 women) free of T2DM at baseline aged between 30 and 79 years who underwent abdominal computed tomography scan between 2012 and 2013 as a part of routine health check-ups were included and followed. VFA, subcutaneous fat area, and VSR on L3 vertebral level were measured at baseline. RESULTS During a median follow-up of 4.8 years, 730 (8.1% for men; 4.3% for women) incident cases of T2DM were identified. Receiver operating characteristic curve analysis showed that the optimal cut-off values of VFA and VSR for predicting incident T2DM were 130.03 cm2 and 1.08 in men, respectively, and 85.7 cm2 and 0.48 in women, respectively. Regardless of sex, higher VFA and VSR were significantly associated with a higher risk of incident T2DM. Compared with the lowest quartiles of VFA and VSR, the highest quartiles had adjusted odds ratios of 2.62 (95% confidence interval [CI], 1.73 to 3.97) and 1.55 (95% CI, 1.14 to 2.11) in men, respectively, and 32.49 (95% CI, 7.42 to 142.02) and 11.07 (95% CI, 3.89 to 31.50) in women, respectively. CONCLUSION Higher VFA and VSR at baseline were independent risk factors for the development of T2DM. Sex-specific reference values for visceral fat obesity (VFA ≥130 cm2 or VSR ≥1.0 in men; VFA ≥85 cm2 or VSR ≥0.5 in women) are proposed for the prediction of incident T2DM.

Abstract
The rapidly increasing prevalence of obesity and obesity-associated morbidity is causing an ever-increasing global burden. Beyond lifestyle modifications, pharmacological approaches to losing body weight to achieve a decrease in cardiometabolic complications are in the spotlight. Pre-existing anti-obesity medications (AOMs) approved for long-term prescription use showed a weight reduction of around 5% more than placebo. In contrast to the modest efficacy of pre-existing AOMs, two newly developed, weekly-administered injectable drugs, semaglutide and tirzepatide, exhibited outstanding weight-loss effects in a series of multinational randomized phase III trials. Considering that these two peptides are the most promising candidates for the upcoming battle in the anti-obesity market, comparison of their efficacy and safety is essential. This review summarizes the body weight reduction efficacy, glycemic control, and safety of semaglutide up to a 2.4-mg dose and tirzepatide up to a 15-mg dose, focusing on the Semaglutide Treatment Effect in People with Obesity (STEP) 2, SURPASS-1, and SURPASS-2 trials, the subjects of which were all patients with type 2 diabetes mellitus.

Abstract
ObjectiveTo investigate the associations between the macular microvasculature assessed by optical coherence tomography angiography (OCTA) and subclinical atherosclerosis in patients with type 2 diabetes.MethodsWe included patients with type 2 diabetes who received comprehensive medical and ophthalmic evaluations, such as carotid ultrasonography and OCTA at a hospital-based diabetic clinic in a consecutive manner. Among them, 254 eyes with neither diabetic macular edema (DME) nor history of ophthalmic treatment from 254 patients were included. The presence of increased carotid intima-media thickness (IMT) (>1.0 mm) or carotid plaque was defined as subclinical atherosclerosis. OCTA characteristics focused on foveal avascular zone (FAZ) related parameters and parafoveal vessel density (VD) were compared in terms of subclinical atherosclerosis, and risk factors for subclinical atherosclerosis were identified using a multivariate logistic regression analysis.ResultsSubclinical atherosclerosis was observed in 148 patients (58.3%). The subclinical atherosclerosis group were older (p < 0.001), had a greater portion of patients who were men (p = 0.001) and who had hypertension (p = 0.042), had longer diabetes duration (p = 0.014), and lower VD around FAZ (p = 0.010), and parafoveal VD (all p < 0.05). In the multivariate logistic regression analysis, older age (p ≤ 0.001), male sex (p ≤ 0.001), lower VD around FAZ (p = 0.043), lower parafoveal VD of both superficial capillary plexus (SCP) (p = 0.011), and deep capillary plexus (DCP) (p = 0.046) were significant factors for subclinical atherosclerosis.ConclusionThe decrease in VD around FAZ, and the VD loss in parafoveal area of both SCP and DCP were significantly associated with subclinical atherosclerosis in patients with type 2 diabetes, suggesting that common pathogenic mechanisms might predispose to diabetic micro- and macrovascular complications.

Abstract
Despite the strong influence of the gut microbiota on atherosclerosis, a causal relationship between atherosclerosis pathophysiology and gut microbiota is still unverified. This study was performed to determine the impact of the gut microbiota on the pathogenesis of atherosclerosis caused by genetic deficiency. To elucidate the influence of the gut microbiota on atherosclerosis pathogenesis, an atherosclerosis-prone mouse model (C1q/TNF-related protein 9-knockout (CTRP9-KO) mice) was generated. The gut microbial compositions of CTRP9-KO and WT control mice were compared. Fecal microbiota transplantation (FMT) was performed to confirm the association between gut microbial composition and the progression of atherosclerosis. FMT largely affected the gut microbiota in both CTRP9-KO and WT mice, and all transplanted mice acquired the gut microbiotas of the donor mice. Atherosclerotic lesions in the carotid arteries were decreased in transplanted CTRP9-KO mice compared to CTRP9-KO mice prior to transplantation. Conversely, WT mice transplanted with the gut microbiotas of CTRP9-KO mice showed the opposite effect as that of CTRP9-KO mice transplanted with the gut microbiotas of WT mice. Here, we show that CTRP9 gene deficiency is related to the distribution of the gut microbiota in subjects with atherosclerosis. Transplantation of WT microbiotas into CTRP9-KO mice protected against the progression of atherosclerosis. Conversely, the transplantation of CTRP9-KO microbiotas into WT mice promoted the progression of atherosclerosis. Treating atherosclerosis by restoring gut microbial homeostasis may be an effective therapeutic strategy.

Abstract
Objective The triglyceride-glucose (TyG) index, the product of fasting triglycerides and glucose, is a useful and cost-effective marker of insulin resistance (IR). Furthermore, the TyG index is a known IR screening tool in healthy young adults but not in those with atherosclerotic cardiovascular disease (CVD). Thus, this study aimed to evaluate the TyG index as a predictor of CVD in healthy young adults. Methods This study enrolled 6,675,424 adults aged 20–39 years without CVD from the National Health Information Database. We categorized them by TyG index quartile from 2009–2017. The study outcomes were stroke, myocardial infarction (MI), and mortality. All outcomes were analyzed by Cox proportional hazards regression analysis while controlling for baseline covariates. Results During a mean 7.4 years of follow-up, 8,506 cases of stroke, 12,312 cases of MI, and 22,667 deaths were recorded. Multivariable-adjusted hazard ratios (HRs) for participants in the highest TyG index quartile demonstrated that they were at higher risk for stroke (HR, 1.253; 95% confidence interval [CI], 1.167–1.346), MI (HR, 1.258; 95% CI, 1.187–1.334), and mortality (HR, 1.151; 95% CI, 1.104–1.200) than those in the lowest TyG index quartile independent of age, sex, smoking, alcohol consumption, physical activity, income, body mass index, blood pressure, and total cholesterol. The HRs for outcomes in the highest quartiles were higher when the TyG index was applied than when triglyceride or fasting glucose alone was applied. Conclusion TyG index, a simple measure reflecting IR, can predict CVD and mortality in young and healthy populations.

Abstract
INTRODUCTION Type 2 diabetes mellitus (T2DM) is a chronic, progressive disease requiring lifelong treatment, and durable medication is essential for maintaining stable glycemic control. This study aimed to evaluate the long-term efficacy of dulaglutide in participants who have continued the drug for more than one year. METHODS We conducted a retrospective study on 605 participants, who used dulaglutide for over one year between 2016 and 2020. Changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose, and bodyweight from baseline to last prescription day were assessed. Adherence was evaluated by the proportion of days covered (PDC), and a PDC value ≥ 0.80 was considered adherent. RESULTS The mean age was 54.0 ± 11.1 years, and 46.1% were female. The mean baseline HbA1c, bodyweight, and duration of diabetes were 8.8% (72.7 mmol/mol), 75.6 kg, and 12.2 years, respectively. During the mean follow-up of 33.1 months, HbA1c and bodyweight decreased by 1.28% (14 mmol/mol, P < 0.001) and by 3.19 kg (P < 0.001), respectively. The participants were highly adherent with PDC ≥ 0.80 in 92.4% of the participants. CONCLUSION In T2DM patients, long-term dulaglutide treatment was effective in maintaining HbA1c and weight reduction. Dulaglutide could be a favorable option of long-term treatment in real-world clinical practice.

INTRODUCTION This study evaluates the efficacy and safety of the free up-titration of basal insulin and fixed-ratio combination (FRC) of basal insulin and glucagon-like peptide-1 receptor agonists (GLP-1RAs) in type 2 diabetes mellitus (T2DM) patients inadequately controlled with GLP-1RA. METHODS With the use of a systematic literature review of PubMed, Embase, Web of Science, and the Cochrane Library databases through July 2021, randomized controlled trials that compared the free up-titration or FRC with remaining on GLP-1RA in T2DM patients uncontrolled with GLP-1RA were included. A comparison of adding basal insulin to maintaining GLP-1RA and an indirect comparison between the two strategies were conducted on the change in HbA1c, fasting plasma glucose (FPG), target achievement [HbA1c < 7.0%], and the risk of confirmed hypoglycemia. The Cochrane Collaboration's tool was used to assess the risk of bias. RESULTS Two free up-titration and two FRC trials involving 1,612 participants, all lasting 26 weeks, were included. Both approaches significantly lowered HbA1c levels (weighted mean difference [WMD] -0.75%, 95% CI -0.97 to -0.53) but increased hypoglycemic risk [risk ratio (RR) 7.59, 95% CI 3.35-17.17] compared to the unchanged GLP-1RA. No significant differences were discovered between the two methods regarding the decrease in HbA1c (WMD 0.08%, 95% CI -1.07% to 1.23%), FPG (WMD -2.29 mg/dl, 95% CI -45.07 to 40.49 mg/dl), target achievement (RR 1.03, 95% CI 0.50-2.14), and hypoglycemic risk (RR 0.32, 95% CI 0.03-3.59). CONCLUSION In patients who failed to reach target HbA1c levels despite the GLP-1RA treatment, both strategies of adding basal insulin, free up-titration and FRC, are comparable options are comparable options.

Abstract
PURPOSE This study evaluated the association between metabolic health status and incident kidney cancer among obese participants. MATERIALS AND METHODS A total of 514,866 individuals were included from the Korean National Health Insurance Service-National Health Screening Cohort. Changes in metabolic health status and obesity from the baseline examination in 2009-2010 to the next biannual examination in 2011-2012 were determined. Based on the status change, obese participants were divided into four groups: stable metabolically healthy obesity, metabolically healthy obesity to metabolically unhealthy obesity, metabolically unhealthy obesity to metabolically healthy obesity, and stable metabolically unhealthy obesity. RESULTS The stable metabolically healthy obesity phenotype did not confer an increased risk of incident kidney cancer, compared to the stable metabolically healthy non-obese group. In contrast, the metabolically healthy obesity to metabolically unhealthy obesity group had a significantly higher risk of incident kidney cancer than the stable metabolically healthy non-obese group. Among patients with metabolically unhealthy obesity at baseline, those who transitioned to the metabolically healthy obese group had no increased risk of kidney cancer, whereas those who remained in metabolically unhealthy obesity status had a higher risk of incident kidney cancer than the stable metabolically healthy non-obese group. The transition or maintenance of metabolic health was a decisive factor for kidney cancer in obese patients. CONCLUSIONS Maintaining or restoring metabolic health should be stressed upon in obese patients to reduce the risk of kidney cancer.

Abstract
BACKGROUND It is not known which type 2 diabetes mellitus (T2DM) patients would most benefit from dipeptidyl peptidase-4 (DPP-4) inhibitor treatment. We aimed to investigate the predictors of response to DPP-4 inhibitors considering degree of DPP-4 inhibition. METHODS This study is a post hoc analysis of a 24-week, randomized, double-blind, phase III trial that compared the efficacy and safety of a DPP-4 inhibitor (gemigliptin vs. sitagliptin) in patients with T2DM. Subjects were classified into tertiles of T1 <65.26%, T2=65.26%-76.35%, and T3 ≥76.35% by DPP-4 inhibition. We analyzed the change from baseline in glycosylated hemoglobin (HbA1c) according to DPP-4 inhibition with multiple linear regression adjusting for age, ethnicity, body mass index, baseline HbA1c, and DPP-4 activity at baseline. RESULTS The mean age was greater in the high tertile group compared with the low tertile group (T1: 49.8±8.3 vs. T2: 53.1±10.5 vs. T3: 55.3±9.5, P<0.001) of DPP-4 inhibition. Although HbA1c at baseline was not different among tertiles of DPP-4 inhibition (P=0.398), HbA1c after 24-week treatment was lower in the higher tertile compares to the lower tertile (T1: 7.30%±0.88% vs. T2: 7.12%±0.78% vs. T3: 7.00%±0.78%, P=0.021). In multiple regression analysis, DPP-4 enzyme inhibition rate was not a significant determent for HbA1c reduction due to age. In subgroup analysis by tertile of DPP-4 inhibition, age was the only significant predictor and only in the highest tertile (R2=0.281, B=-0.014, P=0.024). CONCLUSION This study showed that HbA1c reduction by DPP-4 inhibitor was associated with increasing age, and this association was linked with higher DPP-4 inhibition.

Abstract
Background We aimed to evaluate the efficacy of sodium-glucose cotransporter 2 (SGLT2) inhibitors for managing obesity in non-diabetic overweight or obese patients. Methods For purposes of this study, PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were searched through May 2021. Randomized controlled trials published in English that compared SGLT2 inhibitors with placebo in overweight and obese patients without diabetes were included in the primary analysis. The random effects standardized mean difference ±95% confidence interval (95% CI) was calculated as the effect size. Results Five randomized controlled trials were included to evaluate body weight change, four trials to assess body mass index (BMI), and three trials to assess waist circumference were included. Results showed that the mean body weight loss on SGLT2 inhibitors in obese patients without diabetes was −1.62 kg (95% CI, −2.38 to −0.85 kg) when compared with placebo. Treatment with SGLT2 inhibitors was also associated with a greater reduction in BMI than placebo (weighted mean difference, −0.47 kg/m2; 95% CI, −0.62 to −0.31 kg/m2). The mean reduction in waist circumference with SGLT2 inhibitors versus placebo was 1.29 cm (95% CI, −2.62 to 0.04 cm), which was not statistically significant. There were no significant changes in fat mass, blood pressure, low-density lipoprotein cholesterol or high-density lipoprotein cholesterol with SGLT2 inhibitor treatment. Conclusion A meta-analysis demonstrated that although the weight lowering effect was mild, SGLT2 inhibitors significantly reduced body weight in obese patients without diabetes.

Abstract
The triglyceride glucose (TyG) index has been suggested as a marker for insulin resistance; however, few studies have investigated the clinical implications of markers that combine obesity markers with the TyG index. This study aimed to investigate the associations between non-alcoholic fatty liver disease (NAFLD) and TyG-related markers in healthy subjects in Korea. We enrolled 21,001 asymptomatic participants who underwent hepatic ultrasonography. The homeostasis model assessment of insulin resistance (HOMA-IR), TyG index, TyG-body mass index, and TyG-waist circumference (WC) were subsequently analyzed. NAFLD was diagnosed using hepatic ultrasonography. A multiple logistic regression analysis was performed to evaluate the associations between the quartiles of each parameter and the risk of NAFLD. The increase in the NAFLD risk was most evident when the TyG-WC quartiles were applied; the multivariate-adjusted odds ratios for NAFLD were 4.72 (3.65–6.10), 13.28 (10.23–17.24), and 41.57 (31.66–54.59) in the 2nd, 3rd, and 4th TyG-WC quartiles, respectively, when compared with the lowest quartile. The predictability of the TyG-WC for NAFLD was better than that of the HOMA-IR using the area under the curve. The TyG-WC index was superior to the HOMA-IR for identifying NAFLD in healthy Korean adults, especially in the non-obese population.

Abstract
The global burden of obesity has multiplied owing to its rapidly growing prevalence and obesity-related morbidity and mortality. In addition to the classic role of depositing extra energy, adipose tissue actively interferes with the metabolic balance by means of secreting bioactive compounds called adipokines. While most adipokines give rise to inflammatory conditions, the others with anti-inflammatory properties have been the novel focus of attention for the amelioration of cardiometabolic complications. This review compiles the current evidence on the roles of anti-inflammatory adipokines, namely, adiponectin, vaspin, the C1q/TNF-related protein (CTRP) family, secreted frizzled-related protein 5 (SFRP5), and omentin-1 on cardiometabolic health. Further investigations on the mechanism of action and prospective human trials may pave the way to their clinical application as innovative biomarkers and therapeutic targets for cardiovascular and metabolic disorders.

Abstract
AIM Patients with type 2 diabetes (T2DM) who require injectable therapy have been conventionally treated with insulin. A glucagon-like peptide 1 receptor agonist was recently recommended as first-line injectable treatment, but few studies have investigated the effects of switching from insulin to dulaglutide. This study investigated the clinical efficacy and parameters affecting responses to dulaglutide as an alternative to insulin in patients with T2DM in a real-world clinical setting. METHODS Ninety-eight patients with T2DM who were switched from insulin to dulaglutide therapy were retrospectively evaluated. Changes in HbA1c concentrations were assessed after 6 months of consistent treatment with dulaglutide. Multiple linear regression analysis was performed to evaluate parameters affecting the response to dulaglutide treatment. RESULTS After treatment with dulaglutide for 6 months, patients experienced changes in HbA1c of -0.95% (95% confidence interval [CI]: -1.30% to -0.59%, P < 0.001) and in body weight of -1.75 kg (95% CI: -2.42 to -1.08 kg, P < 0.001). Multiple linear regression analysis showed that higher baseline HbA1c was significantly associated with a greater reduction in HbA1c. The most frequent adverse events were gastrointestinal symptoms. CONCLUSION Switching from insulin to dulaglutide can lead to significant improvement in HbA1c levels and body weight reduction in T2DM patients over 6 months. Higher baseline HbA1c is associated with a better clinical response to dulaglutide.

Abstract
Dulaglutide, a weekly injectable glucagon-like peptide-1 receptor agonist, has demonstrated effectiveness when combined with basal insulin. We examined whether the efficacy of dulaglutide is comparable to that of prandial insulin in kidney transplant (KT) recipients with type 2 diabetes mellitus (T2DM) undergoing multiple daily insulin injection (MDI) therapy. Thirty-seven patients, who switched from MDI therapy to basal insulin and dulaglutide, were retrospectively analyzed. Changes in glycosylated hemoglobin (HbA1c) and fasting plasma glucose (FPG) levels, body weight, and basal insulin dose were evaluated over 6 months. Dulaglutide was comparable to three injections of prandial insulin in terms of glycemic control (HbA1c 7.1% vs. 7.0%; 95% confidence interval [CI], -0.53 to 0.28; P=0.53). The basal insulin and dulaglutide combination resulted in a reduction in FPG levels by 9.7 mg/dL (95% CI, 2.09 to 41.54; P=0.03), in body weight by 4.9 kg (95% CI, 2.87 to 6.98; P<0.001), and in basal insulin dose by 9.52 IU (95% CI, 5.80 to 3.23; P<0.001). Once-weekly dulaglutide may be an effective alternative for thrice-daily prandial insulin in KT recipients with T2DM currently receiving MDI therapy.

Abstract
BACKGROUND Metabolically healthy obese (MHO) phenotype is metabolically heterogeneous in terms of type 2 diabetes (T2D). Previously, the triglyceride and glucose (TyG) index has been considered for identifying metabolic health and future risk of T2D. This study aimed to evaluate the risk of incident T2D according to obesity status and metabolic health, categorized by four different criteria and the TyG index. METHODS The study included 39,418 Koreans without T2D at baseline. The risk of T2D was evaluated based on four different definitions of metabolic health and obesity status and according to the baseline TyG index within each metabolic health and obesity group. RESULTS During the median follow-up at 38.1 months, 726 individuals developed T2D. Compared with the metabolically healthy non-obese (MHNO) group with low TyG index, the MHO group with high TyG index showed increased risk of T2D in all four definitions of metabolic health with multivariate-adjusted hazard ratios of 2.57 (95% confidence interval [CI], 1.76 to 3.75), 3.72 (95% CI, 2.15 to 6.43), 4.13 (95% CI, 2.67 to 6.38), and 3.05 (95% CI, 2.24 to 4.15), when defined by Adult Treatment Panel III, Wildman, Karelis, and homeostasis model assessment (HOMA) criteria, respectively. CONCLUSION MHO subjects with high TyG index were at an increased risk of developing T2D compared with MHNO subjects, regardless of the definition of metabolic health. TyG index may serve as an additional factor for predicting the individual risk of incident T2D in MHO subjects.

Abstract
Purpose Dipeptidyl peptidase-4 (DPP-4) inhibitors lower blood glucose levels and enhance the function of pancreatic β cells. Yet, it is unknown whether posttransplant administration of DPP4 inhibitors is beneficial for pancreas transplant recipients. Methods We thus retrospectively analyzed the records of 312 patients who underwent pancreas transplantation between 2000 and 2018 at Asan Medical Center (Seoul, Korea) and compared the metabolic and survival outcomes according to DPP-4 inhibitor treatment. Results The patients were divided into the no DPP-4 inhibitor group (n = 165; no treatment with DPP-4 inhibitors or treated for <1 month) and the DPP-4 inhibitor group (n = 147; treated with DPP-4 inhibitors for ≥1 month). There were no significant differences in levels of glucose, hemoglobin A1c, and insulin between the 2 groups during 36 months of follow-up. However, the level of C-peptide was significantly higher in the DPP-4 inhibitor group at 1, 6, and 24 months posttransplant (all P < 0.05). Moreover, the DPP-4 inhibitor group had significantly higher rates of overall (log-rank test, P = 0.009) and death-censored (log-rank test, P = 0.036) graft survival during a 15-year follow-up. Conclusion Posttransplant DPP-4 inhibitor administration may help improve the clinical outcomes including β cell function after pancreas transplantation.

Abstract
PURPOSE Type 2 diabetes develops in the presence of chronic overnutrition and genetic susceptibility, and causes insulin resistance and relative insulin deficiency. We hypothesized that islet transplantation can improve insulin sensitivity by modifying the mediators of insulin sensitivity in the pancreas, liver, muscle, and adipose tissues. METHODS Eight-week-old male mice were used as both recipients and donors in this study. To induce type 2 diabetes with partial β-cell failure, the mice were fed a high-fat diet for 4 weeks and then injected with low-dose streptozotocin. Approximately 400 islet cells from a donor mouse were injected into the renal capsule of a recipient mouse for islet transplantation. After 6 weeks following transplantation, the mediators of insulin sensitivity in the pancreas, liver, muscle, and adipose tissues were quantitatively compared between islet-transplanted and non-transplanted groups. RESULTS Intravenous glucose tolerance test showed that whereas the non-transplanted mice failed to show notable reductions in the glucose level, the islet-transplanted mice showed significant reductions in the serum glucose level to ~200 mg/dL at 6 weeks after islet transplantation. The islet-transplanted mice showed significantly higher Matsuda index and significantly lower HOMA-IR than did the non-transplanted mice, thus signifying improved insulin sensitivity. CONCLUSIONS Islet transplantation resulted in improvements in multiple indices of insulin sensitivity in a murine model of type 2 diabetes. Islet transplantation may be utilized to improve insulin sensitivity in patients with type 2 diabetes.

Abstract
OBJECTIVES This study aimed to assess posttransplant changes in insulin sensitivity and β-cell function of pancreas transplant recipients according to the type of diabetes mellitus (DM) and the pretransplant insulin sensitivity measured by the Matsuda Index (MI). METHODS We analyzed 60 patients who underwent pancreas transplantation and oral glucose tolerance test pretransplant and at 1 month posttransplant. RESULTS At 1 month posttransplant, insulin sensitivity did not show significant improvement; particularly, the MI was significantly lower after transplant in recipients with type 1 DM (T1DM) and those with pretransplant MI of 5 or greater. β-cell function was significantly improved after transplant in all recipients regardless of the type of DM and pretransplant MI values. Glucose control was significantly improved in recipients with T1DM and in all recipients regardless of the pretransplant MI values. Additional oral glucose tolerance test at 1 year posttransplant revealed that insulin sensitivity remained unimproved and β-cell function was higher compared with pretransplant. Glucose control had partially reverted to pretransplant levels in recipients with T1DM and those with pretransplant MI of 5 or greater. CONCLUSIONS Unlike β-cell function and glucose control, insulin sensitivity did not significantly improve until posttransplant 1 year after pancreas transplantation regardless of the type of DM or the degree of pretransplant insulin sensitivity.

Abstract
Autophagy is an important process in the pathogenesis of atherosclerosis. C1q/tumor necrosis factor-related protein 9 (CTRP9) is the closest adiponectin paralog. CTRP9 has anti-aging and anti-atherogenic effects, but its roles in autophagy and endothelial senescence are currently unknown. This study aimed to evaluate whether CTRP9 prevents palmitic acid (PA)-induced endothelial senescence by promoting autophagy. After no treatment or pre-treatment of human umbilical vein endothelial cells with CTRP9 prior to PA treatment, the level of senescence was measured by senescence associated acidic β-galactosidase staining and the level of hyperphosphorylated pRB protein. Autophagy was evaluated by LC3 conversion and the level of p62/SQSTM1, a protein degraded during autophagy. Autophagosome-lysosome fusion was detected by fluorescence microscopy. Pre-treatment with CTRP9 attenuated PA-induced endothelial senescence. CTRP9 increased the conversion of LC3-I to LC3-II and decreased p62 levels in a time- and dose-dependent manner. Although both CTRP9 and PA treatment increased LC3 conversion, treatment with PA increased the expression level of p62 and decreased the fusion of autophagosomes and lysosomes, which represented decreased autophagic flux. However, pre-treatment with CTRP9 recovered the autophagic flux inhibited by PA. AMP-activated kinase (AMPK) activation was involved in LC3 conversion and decreased p62 levels induced by CTRP9. CTRP9 inhibits PA-induced endothelial senescence by recovering autophagy and autophagic flux through AMPK activation.

Abstract
BACKGROUND Metabolically healthy obese (MHO) individuals and their association with cardiometabolic diseases have remained controversial. We aimed to explore the risk of incident heart failure (HF) based on the baseline metabolic health and obesity status as well as their transition over 2 years. METHODS The Korean National Health Insurance Service-National Health Screening Cohort data of 514,886 participants were analyzed. Obesity was defined as BMI ≥25 kg/m2 according to the Korean Centers for Disease Control and Prevention. The metabolic health and obesity status were evaluated at baseline and after two years. Study participants were followed to either the date of newly diagnosed HF or the last follow-up visit, whichever occurred first. RESULTS The MHO group comprised 9.1% of the entire population and presented a better baseline metabolic profile than the metabolically unhealthy non-obese (MUNO) and metabolicavlly unhealthy obese (MUO) groups. During the median 71.3 months of follow-up, HF developed in 5,406 (1.5%) participants. The adjusted hazard ratios [HRs (95% CI)] of HF at baseline compared with the metabolically healthy non-obese (MHNO) group were 1.29 [1.20-1.39], 1.37 [1.22-1.53], and 1.63 [1.50-1.76] for MUNO, MHO, and MUO groups, respectively. With the stable MHNO group as reference, transition into metabolically unhealthy status (MUNO and MUO) increased the risk of HF, regardless of the baseline status. Subjects who were obese at both baseline and follow-up showed an increased risk of HF, regardless of their metabolic health status. CONCLUSIONS Metabolic health and obesity status and their transition can predict the risk of incident HF. Losing metabolic health in baseline non-obese and obese individuals and remaining obese in baseline obese individuals showed a significantly increased risk of incident HF. Maintaining good metabolic health and a lean body may prevent the development of HF.
