Cardiovascular Disease Under the Influence of Excess Visceral Fat
Bibliographic record
Abstract
Diabetes and cardiovascular disease have emerged as major threats to human health, and the risk of developing these chronic conditions is increased in individuals with abdominal obesity and the metabolic syndrome. Excess visceral abdominal tissue (VAT) accumulation appears to be a key feature of abdominal obesity contributing to the development of the metabolic syndrome. For instance, excess VAT is accompanied by elevated triglycerides, reduced high-density lipoprotein (HDL) cholesterol, elevated blood pressure, and/or elevated fasting plasma glucose. In addition, the rather normal or only marginally elevated low-density lipoprotein (LDL) cholesterol concentrations in patients with excess VAT could provide misleading information as viscerally obese patients have an increased plasma concentration of small, dense LDL particles. Prospective studies have suggested that even among patients with LDL cholesterol concentrations within normal limits, an increased concentration of small LDL particles is associated with higher risk of cardiovascular disease. With the treatment of abdominal obesity and excess VAT, an increase in patients' LDL particle size and improvements in other cardiovascular risk factors (eg, insulin levels, glucose tolerance, HDL, C-reactive protein [CRP], and adiponectin levels) can be achieved. Waist circumference can be used in clinical practice as a first approach and as a crude index to identify patients who have excess VAT, particularly when the elevated waistline is accompanied by the clinical features of the metabolic syndrome, among which an elevated fasting triglyceride concentration appears to be predictive of a reduced LDL particle size and of further metabolic abnormalities frequently referred to as the metabolic syndrome. Lifestyle changes, including more physical activity and healthier nutritional habits, are the cornerstone of therapy for high-risk abdominally obese patients with an excess of VAT. In addition, results from the RIO-Lipids study, which was conducted in high-risk obese, dyslipidemic patients, have provided evidence that CB1 receptor blockade with rimonabant can induce significant weight loss, and, more importantly, improve the cardiometabolic risk profile beyond what could be explained by the weight loss effects of the drug.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
