Objectives: To test the hypothesis that cardiometabolic risk is attenuated when caregivers are relieved of caregiving stress when the caregiving recipient transitions out of the home.
Design: Longitudinal.
Setting: Participants' homes.
Participants: One hundred nineteen spousal caregivers of a patient with Alzheimer's disease (AD) and 55 noncaregiving controls (mean age of entire sample 75 ± 8, 68% women).
Measurements: Participants underwent up to three yearly assessments of metabolic syndrome (MetS) factors related to adiposity, dyslipidemia, hypertension, and hyperglycemia. Changes in the total number of MetS factors (range: 0-5) 3 months after caregiver transitions were evaluated using random regression models with fixed and time-variant effects for sociodemographic and health-related covariates.
Results: Caregivers had a greater number of MetS factors over time than noncaregivers (1.78 ± 0.13 vs 1.36 ± 0.18, P = .008), which, after the death of the spouse, dropped by 0.46 ± 0.16 (P = .003) being no longer different from those of noncaregivers; this effect was most prominently related to decreases in triglycerides (-22.2 ± 11.0 mg/dL, P = .03), systolic blood pressure (-6.2 ± 2.6 mmHg, P = .02), and diastolic blood pressure (-3.4 ± 1.5 mmHg, P = .03). Placement of the spouse decreased the number of MetS factors only in caregivers with lower levels of depressive symptoms (-0.48 ± 0.18, P = .01) and sleeping difficulties (-0.42 ± 0.18, P = .02) but not in caregivers with higher levels in these measures at postplacement.
Conclusion: High cardiometabolic risk in caregivers decreased to the level of that of noncaregivers within 3 months of death of the spouse with AD, although placement, a transition in the course of dementia caregiving, did not benefit cardiovascular health in highly distressed caregivers.

Evaluating atherogenic index of plasma as a predictor for metabolic syndrome: a cross-sectional analysis from Northern Taiwan.
Front Endocrinol (Lausanne)

Department of Family Medicine, Chang-Gung Memorial Hospital, Taoyuan, Taiwan.
Background: The rising global prevalence of metabolic syndrome (MetS), characterized by a constellation of cardiovascular risk factors, underscores the urgent need to identify reliable predictive biomarkers. We hypothesize that an elevated atherogenic index of plasma (AIP) predicts MetS risk through lipid imbalance, but population-specific variations in its predictive strength remain unexplored. Our study aimed to assess AIP), a ratio of triglycerides to high-density lipoprotein cholesterol, as a predictor of MetS.

Shenzhen Bao'an Chinese Medicine Hospital, Guangzhou University of Chinese Medicine, Shenzhen, China.
Objectives: Despite substantial evidence that visceral obesity is an epidemiological risk factor for hyperuricemia (HUA), studies on the connection between the Metabolic Score for Visceral Fat (METS-VF) and HUA remain insufficient. This research focused on METS-VF's potential role as a risk factor for HUA.
Methods: Notably, 8,659 participants from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 were enrolled in this study.

Objective: This study aims to investigate the correlation between dietary inflammatory index (DII) and mortality resulting from all-cause and cardiovascular diseases (CVD) in adults affected by metabolic syndrome (MetS).
Methods: The focus of this study was to analyze the information of 13,751 adults who had been diagnosed with MetS. DII scores were computed based on a 24-hour dietary intake at the start of the study.

Background: An association exists between obesity and reduced testosterone levels in males. The propose of this research is to reveal the correlation between 15 indices linked to obesity and lipid levels with the concentration of serum testosterone, and incidence of testosterone deficiency (TD) among adult American men.
Methods: The study utilized information gathered from the National Health and Nutrition Examination Survey (NHANES) carried out from 2011 to 2016.

Objectives: Although patients with arthritis have significantly increased cardiovascular disease (CVD) risk, effective prediction tools remain limited. This study aimed to evaluate the predictive value of the Metabolic Score for Insulin Resistance (METS-IR) for CVD events among Chinese patients with arthritis.
Methods: Using data from the China Health and Retirement Longitudinal Study (CHARLS), we conducted a 7-year prospective cohort study (2011-2018) involving 1,059 patients with arthritis.
