AI Article Synopsis
- - The study aimed to create a quick and accurate method to estimate visceral fat area (VFA) at the L4-L5 vertebrae using easily measurable anthropometric variables like waist circumference, age, and subcutaneous fat thickness.
- - A total of 227 participants were divided into modeling and validation groups, and multivariate regression analysis was used to develop an estimation formula that demonstrated strong correlations with measured visceral fat.
- - The final formula for estimating VFA showed that age, waist circumference, and abdominal subcutaneous fat thickness could reliably predict visceral fat, making this method useful for health assessments and epidemiological research.
Article Abstract
Background: Abdominal visceral fat affects the metabolic processes, and is an important risk factor for morbidity and mortality. The purpose of the study was to develop a quick and accurate estimate in the visceral fat area (VFA) of the L4-L5 vertebrae using anthropometric predictor variables that can be measured conveniently.
Methods: A total of 227 individuals participated in this study and were further divided into a Modeling group (MG) and a Validation group (VG). Anthropometrics measurements (height, weight, waist circumference, hip circumference, age, and subcutaneous fat thickness) and VFACT were measured using computer assisted tomography for all participants. Multivariate linear regression analysis was applied to the MG to construct a VFA estimator using anthropometric predictor variables and to evaluate its performance using the VG.
Results: The estimate equation obtained from the MG were VFAANT = -144.66 + 1.84X1 + 1.35X2 + 0.52X3 (r = 0.92, SEE =14.58 cm2, P < 0.001, n = 152). The X1, X2, and X3 variables in the equation were denoted as waist circumference (WC), age, and abdomen subcutaneous fat thickness (AS). In addition, the correlation between VFAANT and VFACT showed a high correlation (r = 0.92).
Conclusion: A rapid and accurate VFA estimation can be achieved by using only age, WC, and AS. The approach in the present study provides an easy and reliable estimate that can be applied widely in health and epidemiology studies.

A 61-year-old woman underwent an emergent operation with sigmoid colon cancer resection, colostomy, and ileostomy on colon perforation. The low ileostoma, caused by intra-abdominal bad conditions, had irritated the surrounding skin after surgery, intermittently forcing the patient to fast for a certain period. Six months after the operation, under the judgment that re-ileostomy, essential for hospital discharge, seemed very difficult through another laparotomy, we attempted to make the ileostoma higher not with pulling the ileum from the abdomen but with lowering the surrounding skin using skin flap formation techniques.

Background: Patients with liver cirrhosis are universally malnourished and the nocturnal snacks intervention is the currently recommended nutritional intervention for patients with liver cirrhosis. Body composition is an important indicator for the assessment of nutritional conditions. We investigated the effects of nocturnal snacks (200 kcal/day) for 3 months on body composition in patients with liver cirrhosis.

Background: For characterizing health states, fat distribution is more informative than overall body size. We used population-based whole-body magnetic resonance imaging (MRI) to identify distinct body composition subphenotypes and characterize associations with cardiovascular disease (CVD) risk.
Methods: Bone marrow, visceral, subcutaneous, cardiac, renal, hepatic, skeletal muscle and pancreatic adipose tissue were measured by MRI in n = 299 individuals from the population-based KORA cohort.

Obesity is a risk factor of developing type 2 diabetes (T2D) and metabolic complications, through systemic inflammation and insulin resistance. It has also been associated with increased bone marrow adipocytes along with increased bone fragility and fracture risk. However, the differential effects of obesity and T2D on bone fragility remain unclear.

Background: The use of visceral obesity as an indicator for predicting female infertility risk has not been well established. The body roundness index (BRI) is a novel, non-invasive indicator of visceral fat; however, previous reports have not addressed the relationship between the BRI and female infertility. This study sought to fill this research gap by investigating the association between the BRI and the risk of female infertility.
