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.

Urology Jun 2024To determine whether early vs. delayed autotransplantation are associated with adverse outcomes in patients undergoing renal autotransplantation.
OBJECTIVE
To determine whether early vs. delayed autotransplantation are associated with adverse outcomes in patients undergoing renal autotransplantation.
METHODS
Patients who underwent renal autotransplantation from June 2012 to September 2022 were divided into two groups based on timing of autotransplant in relation to initial intervention or diagnosis (early cohort: ≤1-year; delayed cohort: >1-year). Primary outcomes were perioperative complications, aborted surgery, renal function (glomerular filtration rate [GFR]), and postoperative complications at most recent follow-up.
RESULTS
Autotransplantation patients (N=72) were predominantly female (68%) and White (54%), with a median age of 49 years. 90% of patients had undergone previous interventions, including stenting (40%) and nephrostomy tubes (49%), primarily for obstruction (64%). Early vs. delayed cohorts had median preoperative disease durations of 143 (IQR 83-222) vs. 673 days (IQR 529-1,703, p<0.001), with similar median follow-up times (879 vs. 818 days, p=0.8). Groups were similar in demographics and comorbidities. There were no significant differences in rates of aborted surgery (15% vs. 4.2%, p=0.3), perioperative complications (15% vs. 17%, p>0.9), long-term complications (49% vs. 48%, p>0.9), or changes in GFR (median change +3 vs. +4, p=0.7). Outcomes were comparable across preoperative disease durations ranging from 6 to 24 months. These findings were confirmed following adjustments for sex, body mass index, American Society of Anesthesiologists classification, race, preoperative creatinine levels, laterality, gastroesophageal reflux disease, diabetes, hypertension, nephrolithiasis, hyperlipidemia, history of colon surgery, urologic surgery, abdominal surgery, and prior interventions in separate logistic models.
CONCLUSIONS
Disease duration before autotransplantation does not influence outcomes, offering reassurance for clinical decision-making in complex cases.

BACKGROUND
The current Institute of Medicine pregnancy weight gain guidelines were developed using the best available evidence, but were limited by substantial knowledge gaps. Some have raised concern that the guidelines for individuals affected by overweight or obesity are too high and contribute to short- and long-term complications for the mother and child.
OBJECTIVE
To determine the association between pregnancy weight gain below the lower limit of the current Institute of Medicine (IOM) recommendations and risk of 10 adverse maternal and child health outcomes among individuals with overweight and obesity.
METHODS
We used data from a prospective cohort study of US nulliparae with prepregnancy overweight (n=955) or obesity (n=897) followed from the first trimester to 2-7 years postpartum. We used multivariable Poisson regression to relate pregnancy weight gain z-scores with a severity-weighted composite outcome consisting of ≥1 of 10 adverse outcomes (gestational diabetes, preeclampsia, unplanned cesarean delivery, maternal postpartum weight increase >10kg, maternal postpartum metabolic syndrome, infant death, stillbirth, preterm birth, small-for-gestational age birth, and childhood obesity).
RESULTS
Pregnancy weight gain z-scores below, within, and above the IOM-recommended ranges occurred in 5%, 13%, and 80% of pregnancies with overweight and 17%, 13%, and 70% of pregnancies with obesity. There was a positive association between pregnancy weight gain z-scores and all adverse maternal outcomes, childhood obesity, and the composite outcome. Pregnancy weight gain z-scores below the lower limit of the recommended ranges (<6.8 kg for overweight, <5 kg for obesity) were not associated with the severity-weighted composite outcome. For example, compared with the lower limit, adjusted rate ratios (95% confidence interval) for z-scores of -2 standard deviations in pregnancies with overweight (equivalent to 3.6kg at 40 weeks) and obesity (-2.8kg at 40 weeks) were 0.99 (0.91, 1.06) and 0.97 (0.87, 1.07).
CONCLUSIONS
These findings support arguments to decrease the lower limit of recommended weight gain ranges in these prepregnancy BMI groups.

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.

BACKGROUND
Effective control of postprandial blood glucose (PBG) level is essential for the prevention and treatment of diabetes and its complications. Several flavonoids have attracted much attention due to their significant PBG-lowering effects. However, there is still a certain gap in the in vivo hypoglycemic activity of most flavonoids compared to first-line drugs available on the market, and are still lack of the PBG-lowering effects of 8-hydroxyflavones and their structure-activity relationship.
PURPOSE
Evaluate hypoglycemic effects of 8-hydroxyflavones from Rhodiola crenulata in vitro and in vivo, especially comparatively analyze the relationship between hypoglycemic effects and flavonoid configuration and reveal the possible mechanism of 8-hydroxyflavones in lowering hyperglycemia.
METHODS
Starch, maltose, sucrose, and glucose tolerance tests in both diabetic and normal mice were used to evaluate and compare the hypoglycemic effects of 8-hydroxyflavones rhodiosin (RHS), rhodionin (RHN), and herbacetin (HBT). Molecular docking, enzyme kinetics, and immunofluorescence analysis were used to research the possible hypoglycemic mechanisms of 8-hydroxyflavones.
RESULTS
RHS (5 and 10 mg/kg) could efficiently decrease PBG levels in both normal and diabetes mice. Moreover, RHS, RHN, and HBT all had significant PBG-lowering effects in transgenic diabetes mice, and the effects were equivalent to or stronger than acarbose. Further mechanism research indicated that 8-hydroxyflavones achieved PBG-lowering effects by inhibiting both the activity and production of glycosidase. Notably, we have innovatively discovered that inhibiting the expression of glycosidases rather than just their activities may be a new target for hypoglycemic drugs.
CONCLUSION
We have firstly comprehensively and systematically clarified PBG-lowering effects of 8-hydroxyflavones from Rhodiola crenulata, and revealed their structure-activity relationships and hypoglycemic mechanisms. The study demonstrated that the substitution of 8-hydroxy groups in flavonoids could significantly enhance their hypoglycemic effects, which were equivalent to or stronger than commercially available drug acarbose. 8-Hydroxyflavones could be used as therapeutic or health drugs with significant potential to reduce postprandial hyperglycemia.

The primary cause of the pandemic scale of type 2 diabetes (T2D) is the excessive and/or abnormal accumulation of adiposity resulting from a chronic positive energy balance. Any form of weight loss dramatically affects the natural history of T2D, favoring prevention, treatment, and even remission in the case of significant weight loss. However, weight regain, which is often accompanied by the recurrence or worsening of obesity complications such as T2D, is an inevitable biological phenomenon that is an integral part of the pathophysiology of obesity. This can occur not only after weight loss, but also during obesity treatment if it is not effective enough to counteract the physiological responses aimed at restoring adiposity to its pre-weight-loss equilibrium state. Over the past few years, many controlled and randomized studies have suggested a superior efficacy of bariatric surgery compared to conventional therapy in terms of weight loss, glycemic control, and rates of T2D remission. Recently, the therapeutic armamentarium in the field of diabetology has been enriched with new antihyperglycemic drugs with considerable efficacy in reducing body weight, which could play a pathogenetic role in the remission of T2D, not through the classical incretin effect, but by improving adipose tissue functions. All these concepts are discussed in this position statement, which aims to deepen the pathogenetic links between obesity and T2D, shift the paradigm from a "simple" interaction between insulin resistance and insulin deficiency, and evaluate the efficacy of different therapeutic interventions to improve T2D management and induce diabetes remission whenever still possible.

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.

BACKGROUND
This study investigates the correlation between thyroid hormone levels and metabolic dysfunction in patients with type 2 diabetes mellitus (T2DM) who exhibit normal thyroid function and metabolic dysfunction associated with steatotic liver disease (MASLD).
OBJECTIVE
The objective is to identify a scientific basis for the management of T2DM complicated by MASLD, aiming to refine clinical strategies and enhance patient well-being.
METHODS
Statistical analysis was conducted using SPSS 26.0, employing independent sample t-tests for normally distributed data and logarithmic transformations for non-normal data to meet analysis prerequisites. Multifactorial logistic regression analysis elucidated the impact of various factors on the risk of MASLD in T2DM patients.
RESULTS
Elevated levels of FT3 may be associated with an increased risk of nonalcoholic fatty liver disease. Additionally, the FT3/FT4 ratio has been validated as an effective serological marker for predicting the risk of MASLD. In patients with DM2 and normal thyroid function, changes in thyroid hormone levels are closely related to the occurrence of MASLD. Elevated levels of FT3, total triiodothyronine (TT3), and thyroid-stimulating hormone are associated with an increased risk of MASLD.
CONCLUSION
FT3, TT3, and thyroid-stimulating hormone have important clinical value in the diagnosis of patients with T2DM complicated with MASLD.

Observational Study
Diabetic foot (DF) ulcer is one of the common complications of diabetic patients, with high incidence and amputation rate, which seriously affects the quality of life and health of patients. Therefore, how to effectively prevent and treat DF ulcers and reduce amputation rate has become an urgent problem in the medical field. As a comprehensive nursing model for patients with DF ulcers, comprehensive nursing intervention is designed to improve the therapeutic effect and prognosis and reduce the rate of amputation. Convenient sampling method was used to select 360 patients with DF who received routine care for DF ulcers from July 2013 to July 2023 for retrospective cohort analysis. According to the existence of exposure factors (comprehensive nursing intervention), 180 cases were divided into observation group and comparison group. The basic demographic data, amputation rate, severity of foot ulcer, neuropathy and vascular disease, and blood glucose control were compared between the 2 groups. The data was analyzed using SPSS26.0. Harman single factor test was used to check whether there was common method bias in the study data. Descriptive analysis, Spearman rank correlation analysis and multiple linear regression analysis were used to analyze the current situation of amputation rate of DF patients and the influence of comprehensive nursing intervention on the amputation rate of DF patients. The amputation rate was 2.8% in the Observation group compared to 8.3% in the Comparison group. The amputation rate of the observation group was generally higher in the age group, and the amputation rate of the observation group was higher in the middle school education level and below and the economic status of <5000 yuan. The difference was statistically significant (P < .05). Age (odds ratio [OR] = 1.96; 95% confidence interval [CI]: 0.88-4.38), education level (OR = 1.30; 95% CI: 1.69-6.46), economic status (OR = 2.28; 95% CI: 1.69-10.85) was an independent risk factor for amputation rate (P < .05). Comprehensive nursing interventions have played a positive role in reducing the rate of amputation in patients with DF.

Meta-Analysis
BACKGROUND
Frailty has been identified as a risk factor for adverse outcomes in older adults with diabetes. This study aimed to investigate the impact of frailty on the prognosis of older adults with diabetes through a systematic review and meta-analysis, with the goal of offering insights for clinical decision-making.
METHODS
PubMed, Web of Science, Embase, Cochrane were systematically searched from inception to September 10th, 2023. Reviewers independently selected studies, extracted data and evaluated the quality of studies. Stata 15.1 Software was used to perform the meta-analysis. The primary outcomes of this study were mortality, hospitalization and disability, and the secondary outcomes were diabetes complications (including nephropathy, microvascular complications, macroangiopathy, cardiovascular events, hypoglycemia) and urolithiasis.
RESULTS
A total of 14 studies were included in this study, with low risk of bias and moderate to good quality. The results showed that frailty increased the risk of mortality (HR 1.91, 95% CI 1.55-2.35, P < .001), hospitalization (HR 2.19, 95% CI 1.53-3.13, P < .001), and disability in older adults with diabetes (HR 3.84, 95% CI 2.35-6.28, P < .001). In addition, frailty was associated with diabetes complications (including nephropathy, microvascular complications, macroangiopathy, cardiovascular events, hypoglycemia), urolithiasis.
CONCLUSIONS
Frailty is an important predictor of adverse outcomes, such as mortality, hospitalization, and disability in older adults with diabetes. Accurate assessment of the frailty in older adults with diabetes can help improve the adverse outcomes of patients.
