AI Article Synopsis
- The study investigates the relationship between various weight metrics (weight suppression, weight suppression at lowest weight, and weight rebound) and the clinical severity of eating disorders (ED).
- A total of 303 patients were assessed, revealing that weight suppression at their lowest weight strongly correlates with the severity of anorexia nervosa and bulimia nervosa as measured by the Eating Disorder Examination Questionnaire (EDE-Q).
- The findings suggest that weight suppression at lowest weight could be an effective indicator of ED severity, highlighting a need for further research into its role in assessment and treatment.
Article Abstract
Objectives: Weight suppression (WS) defines the difference between the highest weight in adulthood and the current weight. WS at lowest weight is the difference between the highest and the lowest ever weight. Weight rebound is the difference between the past lowest weight and current weight. The distinction in the capacities of WS, weight rebound, and WS at the lowest weight remains unclear regarding their efficacy in forecasting clinical endpoints. This study assessed the relationship between WS, WS at lowest weight and/or weight rebound and eating disorder (ED) clinical severity.
Methods: In this retrospective cohort study, adult participants were selected at the Outpatient Unit for multidisciplinary assessment of ED, Montpellier, France, between February 2012 and October 2014 and May 2017 and January 2020. ED clinical severity was evaluated using the Eating Disorder Examination Questionnaire (EDE-Q).
Results: The sample included 303 patients: 204 with anorexia nervosa (AN) and 99 with bulimia nervosa (BN). The EDE-Q total score was positively correlated with WS at lowest weight in patients with AN (Spearman's rho = 0.181, p = 0.015) and with BN (Spearman's rho = 0.377; p < 0.001). It was also positively correlated with weight rebound (Spearman's rho = 0.319; p = 0.003) in patients with BN. In the multivariate analysis, EDE-Q total score was associated with WS at lowest weight only in patients with BN (β = 0.265; p = 0.03).
Conclusion: WS at lowest weight seems to be a good measure of ED clinical severity. More research is needed for better understanding WS at lowest weight in assessment and treatment of patients with ED.

Visual-Numeric Endometriosis Scoring System (VNESS) for mapping surgical findings: A validation study.

Background: Several endometriosis classification systems have been proposed and published but the search for a universal language that communicates the complexity, laterality and severity of this disease continues. The authors introduce the Visual-Numeric Endometriosis Scoring System. VNESS is a novel system for describing surgical findings in each compartment of the pelvis in a way that is simple to use, visually intuitive and mirrors a laparoscopic image of the pelvis.

In tissues of toothed whales from the Adriatic Sea (muscle, liver, kidney, lung, spleen, adipose tissue and skin) the concentrations of cadmium (Cd), lead (Pb) and arsenic (As) were analysed. In total, 186 dolphins were analysed; 155 bottlenose (Tursiops truncatus), 25 striped (Stenella coeruleoalba) and 6 Risso's dolphins (Grampus griseus). Cadmium concentrations in tissue samples ranged from 0.

Unlabelled: Seed size is an economically important trait that directly determines the seed yield in soybean. In the current investigation, we used an integrated strategy of linkage mapping, association mapping, haplotype analysis and candidate gene analysis to determine the genetic makeup of four seed size-related traits viz., 100-seed weight (HSW), seed area (SA), seed length (SL), and seed width (SW) in soybean.

Aim: Adverse events impact patients as primary victims including their families, while healthcare providers are impacted as second victims. These incidents have serious psychological and physical impacts on healthcare providers' quality of life and their ability to execute their jobs. As no studies have been conducted in the Middle East to explore the experiences of second victims among nurses, this study examined the relationship between nurses' second victim experiences, turnover and absenteeism.

Background: Frailty poses a considerable public health challenge because of its association with negative health consequences. Although obesity is recognized as a contributor to frailty, conventional measures fail to adequately account for the effects of visceral adiposity. The study aimed to investigate the associations between the visceral adiposity index (VAI) or lipid accumulation product (LAP) and frailty.
