This study aimed to develop and validate a machine learning (ML) model tailored to the Korean population with type 2 diabetes mellitus (T2DM) to provide a superior method for predicting the development of cardiovascular disease (CVD), a major chronic complication in these patients. We used data from two cohorts, namely the discovery (one hospital; n = 12,809) and validation (two hospitals; n = 2019) cohorts, recruited between 2008 and 2022. The outcome of interest was the presence or absence of CVD at 3 years. We selected various ML-based models with hyperparameter tuning in the discovery cohort and performed area under the receiver operating characteristic curve (AUROC) analysis in the validation cohort. CVD was observed in 1238 (10.2%) patients in the discovery cohort. The random forest (RF) model exhibited the best overall performance among the models, with an AUROC of 0.830 (95% confidence interval [CI] 0.818-0.842) in the discovery dataset and 0.722 (95% CI 0.660-0.783) in the validation dataset. Creatinine and glycated hemoglobin levels were the most influential factors in the RF model. This study introduces a pioneering ML-based model for predicting CVD in Korean patients with T2DM, outperforming existing prediction tools and providing a groundbreaking approach for early personalized preventive medicine.

AIMS
To study the prevalence of cystic fibrosis related liver disease (CFLD) as defined by ultrasound (US) and describe difference in clinical and radiological features in those with CFLD and those without CFLD (nCFLD); with and without portal hypertension (PHT and nPHT).
METHODS
Children with CF (CwCF) from our clinic who had regular screening liver US from 3 years of age were included. Liver parenchyma findings were classified into normal, homogeneous, heterogeneous and nodular. For our study, we defined PHT as US evidence of splenomegaly and/or ascites, abnormal portal flow, varices, ligamentum teres recanalization if present. Demographic, clinical, nutritional and lung function between the two groups-CFLD/nCFLD; and subgroups- PHT and nPHT were compared. Gamma glutamyl transferase (GGT)/ platelet ratio (GPR) as a marker of fibrosis was measured.
RESULTS
From 227 CwCF,40 (17 %) were excluded (below the age of 3 years or alternative cause of liver disease). Of the remaining 187, 107 (57 %) had a normal US, 80 (43 %) had CFLD; 25 (13.4 %) had PHT. There was no significant difference in demographics, BMI-z score, lung function, presence of gastrostomy or pancreatic insufficiency in CFLD vs nCFLD and PHT vs nPHT. CF related diabetes mellitus (CFRD) was significantly associated with CFLD vs nCFLD (P = 0.0086). GGT was higher and platelet count was lower in PHT vs nPHT (P = 0.0256 and P = 0.0001). Nodularity was strongly associated with an elevated GPR (P = 0.016). There was a strong association between nodularity on US and PHT (P = 0.0006).
CONCLUSION
Nodularity is a clear marker for advanced liver disease with higher scores for a non-invasive marker for fibrosis. There was no difference in nutrition and FEV1 between advanced liver disease and absent/ milder liver disease.

AIM
To assess oral health-related knowledge, attitude, and practices (KAP) of patients with diabetes mellitus (DM) attending public diabetic clinics in Dar es Salaam, Tanzania.
METHODOLOGY
This study involved adult patients diagnosed with DM. A questionnaire with questions related to oral health KAP was used. Data analysis was done using SPSS software v26. Multivariate regression analysis was utilized for response analysis. An alpha of less than 0.05 was considered to indicate statistical significance.
RESULTS
Participants with good levels of KAP related to oral health comprised 51.0%, 82.3%, and 20.6%, respectively. The odds of good oral health knowledge among participants were almost 2 folds higher in participants with high education levels and 7 folds higher in those who had been referred to a dentist by a physician. Participants with good oral health knowledge had 5.5 times higher odds of having a good attitude. The participants with high education levels were almost 3 times more likely to have good practice.
CONCLUSION
About half of the patients with DM have good oral health-related knowledge. A majority have good compliance towards oral health, but only a limited number have good oral health-related practices. The level of education and previous referrals to dental professionals were found to be predictors of good knowledge regarding dental health.

INTRODUCTION
The nature of the relationship between inflammation, cardiovascular (CV) risk factors and atherosclerosis in axial spondyloarthritis (axSpA) remains largely unknown and sex differences in this regard are yet to be assessed.
METHODS
Study including 611 men and 302 women from the Spanish multicentre AtheSpAin cohort to assess CV disease in axSpA. Data on CV disease risk factors were collected both at disease diagnosis and at enrolment, and data on disease activity, functional indices and carotid ultrasonography only at enrolment.
RESULTS
After a median disease duration of 9 years, patients of both sexes who at disease diagnosis had elevated acute phase reactants (APRs), more frequently had hypertension and obesity. The same occurred with dyslipidaemia in men and with diabetes mellitus in women. At enrolment, CV risk factors were independently associated with APR and with activity and functional indices, with various sex differences. C reactive protein (CRP) values were inversely associated with HDL-cholesterol in men (β coefficient: -1.2 (95% CI: -0.3 to -0.07) mg/dL, p=0.001), while erythrocyte sedimentation rate values were positively associated with triglycerides in women (β coefficient: 0.6 (95% CI: 0.04 to 1) mg/dL, p=0.035). Furthermore, only women showed an independent relationship between insulin resistance parameters and APR or disease activity. Both men and women with high-very high CV risk according to the Systematic Assessment of Coronary Risk Evaluation 2 and CRP levels higher than 3 mg/L at diagnosis of the disease presented carotid plaques significantly more frequently than those with normal CRP levels at disease diagnosis.
CONCLUSION
Inflammation is associated with atherosclerosis and CV disease in axSpA. A gender-driven effect is observed in this relationship.

Review
The prevalence and impact of type 2 diabetes mellitus (T2DM) is a major global health problem. The treatment process of T2DM is long and difficult to cure. Therefore, it is necessary to explore alternative or complementary methods to deal with the various challenges brought by T2DM. Natural plant polysaccharides (NPPs) have certain potential in the treatment of T2DM. However, many studies have not considered the relationship between the structure of NPPs and their anti-T2DM activity. This paper reviews the relevant anti-T2DM mechanisms of NPPs, including modulation of insulin action, promotion of glucose metabolism and modulation of postprandial glucose levels, anti-inflammation and modulation of gut microbiota (GM) and metabolism. This paper provides an in-depth study of the conformational relationships of NPPs and facilitates the development of anti-T2DM drugs or dietary supplements with NPPs.

Ophthalmology. Retina Jun 2024To demonstrate the therapeutic similarity of CT-P42 compared to reference aflibercept (Eylea®) in adult patients with diabetic macular edema (DME).
OBJECTIVE
To demonstrate the therapeutic similarity of CT-P42 compared to reference aflibercept (Eylea®) in adult patients with diabetic macular edema (DME).
DESIGN
Randomized, active-controlled, double-masked, Phase III clinical trial PARTICIPANTS: Patients with a diagnosis of either type 1 or 2 diabetes mellitus (DM) with DME involving the center of the macula.
METHODS
Patients were randomized (1:1) to receive either CT-P42 or reference aflibercept (2 mg/0.05 mL) by intravitreal injection every 4 weeks (5 doses) then every 8 weeks (4 doses) in the main study period. Results up to Week 24 are reported herein.
MAIN OUTCOME MEASURES
The primary endpoint was mean change from baseline at Week 8 in best corrected visual acuity (BCVA) using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Equivalence between CT-P42 and reference aflibercept was to be concluded if the two-sided 95% confidence interval (CI) (global assumptions) and two-sided 90% CI (US Food and Drug Administration [FDA] assumptions) for the treatment difference fell entirely within the equivalence margin of ±3 letters, as assessed in the full analysis set.
RESULTS
Overall, 348 patients were randomized (CT-P42: 173; reference aflibercept: 175). BCVA improved from baseline to Week 8 in both groups, with a least squares mean (standard error) improvement of 9.43 (0.798) and 8.85 (0.775) letters in the CT-P42 and reference aflibercept groups, respectively. The estimated between-group treatment difference was 0.58 letters, with the CIs within the pre-defined equivalence margin of ±3 letters (95% CI -0.73, 1.88 [global]; 90% CI -0.52, 1.67 [FDA]). Through Week 24, other efficacy results for the two groups, in terms of change in BCVA and retinal central subfield thickness, as well as ETDRS Diabetic Retinopathy Severity Scale score, supported therapeutic similarity. Pharmacokinetics, usability, safety (including the proportions of patients experiencing at least one treatment-emergent adverse event [CT-P42: 50.3%; reference aflibercept: 53.7%]), and immunogenicity were also comparable between groups.
CONCLUSIONS
This study in patients with DME demonstrated equivalence between CT-P42 and reference aflibercept (2 mg/0.05 mL) in terms of efficacy, with similar pharmacokinetic, usability, safety, and immunogenicity profiles.

PURPOSE
The purpose of this study was to retrospectively analyze the degree of renal function deterioration after renal cryoablation in patients with a solitary functioning kidney based on ablation volume.
MATERIALS AND METHODS
Over a 15-year period, 81 percutaneous cryoablations were performed in solitary functioning kidneys. After exclusion of patients with baseline end-stage renal disease(ESRD) and insufficient follow up, analysis was performed on 65 procedures in 52 patients (40 male, mean age 63.5 years). The post-cryoablation renal function was based on the lowest serum creatinine within 6 months post-procedure. Renal function change was defined as percentage glomerular filtration rate(GFR) change. Volumetric analysis was performed on the target lesion, renal parenchyma, and ablation zone.
RESULTS
The median tumor diameter was 2.0cm (range 0.8-4.7cm). The median baseline GFR decreased from 56.4 mL/min/1.73m (range 17.5-89.7) to 46.9 (range 16.5-89.7) at median 95 days (p<0.001), equating to an -7.9% median renal function change (range -45.0 to +30.7). All patients had stage 2 or worse chronic kidney disease and baseline function did not correlate with renal function change. The median volume of ablated parenchyma was 19.7mL (range 2.4-87.3mL), equating to 8.1% (range 0.7-37.2%) of total parenchyma. The volume of parenchymal volume ablated correlated significantly with renal function loss, while age, hypertension, and diabetes mellitus did not. No patients developed ESRD within 1 year after cryoablation.
CONCLUSION
Cryoablation in solitary functioning kidneys resulted in a modest reduction in renal function, even in patients with chronic kidney disease and ablations up to 20% of renal parenchymal volume.

Disparities in metabolic dysfunction-associated steatotic liver disease and cardiometabolic conditions in low and lower middle-income countries: systematic analysis from the global burden of disease study 2019.
OBJECTIVE
Metabolic dysfunction-associated steatotic liver disease (MASLD) and cardiometabolic conditions affect populations across economic strata. Nevertheless, there are limited epidemiological studies addressing these diseases in low (LICs) and lower-middle-income countries (lower MICs). Therefore, an analysis of the trend of MASLD and cardiometabolic conditions in these countries is necessary.
METHODS
From 2000 to 2019, jointpoint regression analysis was employed to calculate the prevalence, mortality, and disability-adjusted life years (DALYs) for cardiometabolic conditions including MASLD, type 2 diabetes mellitus (T2DM), dyslipidemia (DLP), hypertension (HTN), obesity, peripheral artery disease (PAD), atrial fibrillation and flutter (AF/AFL), ischemic heart disease (IHD), stroke, and chronic kidney disease from HTN and T2DM, in LICs and lower MICs (according to the World Bank Classification 2019) using the Global Burden of Disease 2019 data.
RESULTS
Among the eleven cardiometabolic conditions, MASLD (533.65 million), T2DM (162.96 million), and IHD (76.81 million) had the highest prevalence in LICs and Lower MICs in 2019. MASLD represented the largest proportion of global prevalence in these countries (43 %). From 2000 to 2019, mortality in LICs and lower MICs increased in all cardiometabolic conditions, with obesity-related mortality having the highest increase (+134 %). During this timeframe, there were increased age-standardized death rates (ASDR) from obesity, PAD, and AF/AFL. From all conditions, the DALYs-to-prevalence ratio was higher in LICs and lower MICs than the global average.
CONCLUSION
The burden of MASLD and cardiometabolic conditions is increasing worldwide, with LICs and lower MICs experiencing higher disability per prevalence. As these conditions are preventable, counteracting these trends requires not only the modification of ongoing actions but also the strategizing of immediate interventions.

Review
Diabetes mellitus (DM) is a metabolic disorder characterized by hyperglycemia, with its prevalence linked to both genetic predisposition and environmental factors. Epigenetic modifications, particularly through histone deacetylases (HDACs), have been recognized for their significant influence on DM pathogenesis. This review focuses on the classification of HDACs, their role in DM and its complications, and the potential therapeutic applications of HDAC inhibitors. HDACs, which modulate gene expression without altering DNA sequences, are categorized into four classes with distinct functions and tissue specificity. HDAC inhibitors (HDACi) have shown efficacy in various diseases, including DM, by targeting these enzymes. The review highlights how HDACs regulate β-cell function, insulin sensitivity, and hepatic gluconeogenesis in DM, as well as their impact on diabetic cardiomyopathy, nephropathy, and retinopathy. Finally, we suggest that targeted histone modification is expected to become a key method for the treatment of diabetes and its complications. The study of HDACi offers insights into new treatment strategies for DM and its associated complications.
