Purpose: To evaluate the effect of left gastric artery embolization (LGAE) on glycated hemoglobin (HbA1c) in a prospective obese, prediabetic cohort.
Materials And Methods: This prospective pilot study included 10 obese, prediabetic patients (7 females and 3 males; mean age 37.5 ± 8.8 years; range 28-51 years) admitted to the Interventional Radiology Unit between January 2017 and June 2018 for LGAE for weight reduction. The main inclusion criteria were body mass index (BMI) >30 kg/m and HbA1c ranging from 5.7 to 6.4. Body weight, BMI, and HbA1c were assessed for each patient preprocedure and at 6 months postprocedure. Statistical analysis was performed using a paired sample t test.
Results: The baseline mean body weight, BMI, and HbA1c were 107.4 ± 12.8 kg, 37.4 ± 3.3 kg/m, and 6 ± 0.2, respectively. Concerning complications, no serious adverse events were detected. Six months after the procedure, the mean body weight and BMI significantly decreased to 98 ± 11.6 kg and 34.1 ± 3 kg/m, respectively (P < .0001). A paired sample t test showed a significant reduction in HbA1c from pre- to postprocedure (6.1 ± 0.2 preprocedure vs 4.7 ± 0.6 postprocedure, P < .0001). The mean percent reductions in body weight, BMI, and HbA1c were 8.9% ± 1.2, 8.8% ± 1, and 21.4% ± 8.9, respectively. A statistically significant positive correlation was found between BMI and HbA1c after the procedure (r = 0.91, P = .0002).
Conclusions: LGAE is well tolerated and leads to clinically significant decreases in weight and HbA1c in obese, prediabetic patients.

A better diet quality based on the Healthy Eating Index-2020 is associated with lower energy intake and age but not with a pre-diabetes/T2DM diagnosis among Hispanic women with overweight/obesity.

Low diet quality is related to obesity and type 2 diabetes mellitus (T2DM) risk among Hispanic women. This cross-sectional study compared diet quality among Hispanic women with overweight/obesity based on their T2DM diagnosis (pre-diabetes/T2DM group, n = 104 vs no diagnosis, at-risk group, n = 84). It was hypothesized that having a pre-diabetes or T2DM diagnosis would be associated with better diet quality based on the Healthy Eating Index (HEI)-2020 score.

The enzyme 12-lipoxygenase (12-LOX) catalyzes the formation of pro-inflammatory eicosanoids and is known to promote the migration of macrophages, yet its role in obesity-associated inflammation remains incompletely understood. Furthermore, differences between mouse and human orthologs of 12-LOX have limited efforts to study existing pharmacologic inhibitors of 12-LOX.

Obesity and type 2 diabetes (T2D) are associated with significant alterations in various metabolic biomarkers. Isthmin-1 (Ism1) has recently emerged as a potential marker of metabolic health and was shown in animal studies to associate with metabolic-associated fatty liver disease (MAFLD). In this study, we aimed to investigate the circulatory levels of Ism1 in individuals with obesity compared to non-obese individuals and evaluate their association with insulin resistance, MAFLD, and T2D.

Alopecia areata (AA) is a non-scarring inflammatory hair loss condition associated with various immune-mediated comorbidities. Prediabetes, characterized by elevated blood glucose levels not yet high enough to be classified as diabetes, significantly increases the risk of developing type 2 diabetes mellitus (T2DM) and cardiovascular complications. The associations between AA obesity and prediabetes have long been investigated in an attempt to identify preventable risk factors, yet the literature is relatively scarce and inconclusive.

Background: Despite the substantial burden of obesity in the United States (US), data on the comprehensive range of comorbidities in different age groups is limited. This study assessed the prevalence of various comorbidities among people diagnosed with obesity (as per ICD-10 diagnosis code) across age cohorts and compared how they differ from people without obesity.
Methods: This cross-sectional study analyzed individuals from all four regions (Midwest, Northeast, South, and West) of the US who had continuous insurance coverage from 2018 to 2020, using a large health insurance claims database (Merative™ MarketScan).
