Objective: Loss of control (LOC) eating (feeling unable to control food type/amount eaten) during pregnancy is common and linked to risk for poor cardiovascular health (CVH), but it is unclear whether prenatal LOC eating directly relates to CVH during pregnancy. The current study tested associations between prenatal LOC eating and CVH during pregnancy in a sample with prepregnancy body mass index (BMI) ≥ 25.
Method: At 12-20 weeks' gestation, participants ( = 124) self-reported: prenatal LOC eating, diet, physical activity, nicotine use, sleep; height/weight were measured. Data were collected during 2015-2017. We dichotomized LOC eating (0 = ; 1 = ) and scored CVH metrics using Life's Essential 8 to create a composite CVH score (range = 0-100; higher = better). Linear and binary logistic regression models tested if LOC eating is related to composite CVH score and odds of scoring (0)/ (1) on each CVH metric, respectively. All models employed propensity score adjustment, since those with/without LOC eating may differ in ways affecting CVH, and covaried for: age, gestational age, prepregnancy BMI, ethnicity, race, education, and income.
Results: Compared to those without, participants with LOC eating had significantly poorer composite CVH scores ( = -9.27, (111) = -2.70, < .01) and lower odds of scoring moderate-high on nicotine use (OR = 0.20, 95% CI [0.04, 0.85], = .03) and sleep duration (OR = 0.19, 95% CI [0.04, 0.83], = .03) CVH metrics.
Conclusions: Prenatal LOC eating was associated with poorer CVH during pregnancy in this sample with prepregnancy BMI ≥ 25, even after controlling for propensity of experiencing LOC eating and known risk factors for poor CVH. Thus, prenatal LOC may represent a modifiable factor related to prenatal health risk. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Background: Pathological eating and addictive processes are linked to obesity. Food addiction (FA) involves hedonic eating of highly palatable foods, accompanied by addictive symptoms like craving, loss-of-control (LOC) eating, and withdrawal. The main objectives of this study were to assess FA prevalence and symptoms in bariatric surgery candidates, and its relationship with depression, dysregulated eating, and 1- year postoperative weight loss (WL).

Objective: Dysregulated eating is common among youth and is associated with trait-level negative affect and emotion regulation difficulties. Despite the transient nature of affect, momentary associations among affect and eating behavior are unclear, which limits development of more impactful treatment tools, such as "just-in-time" intervention approaches (JITAI). The current study (N = 62) drew from two ecological momentary assessment (EMA) studies involving children and adolescents who endorsed loss of control (LOC) eating symptoms during a two-week assessment period.

Rapunzel syndrome is a rare and severe form of trichobezoar, characterized by the presence of hair masses in the stomach that often extend into the bowel, resembling the legendary "Rapunzel's" long hair. : This review examines the clinical, diagnostic, forensic, and post-mortem aspects associated with Rapunzel syndrome, with a focus on cases resulting in mortality or those at high risk of death due to complications. In particular, the review systematically analyzes the existing literature on fatal cases of Rapunzel syndrome, emphasizing insights into risk factors, clinical manifestations, diagnostic methods, autopsy findings, and preventive measures to provide a focused understanding of these critical aspects.

Disordered eating behavior has been linked to suboptimal weight outcomes following metabolic and bariatric surgery (MBS), thereby threatening the most efficacious treatment for severe obesity. While up to 40% of patients may experience loss of control (LOC) eating following MBS, mechanisms driving this behavior are not fully understood. Preliminary evidence suggests that high levels of negative affect (NA) in the moment prompt LOC eating post-MBS; however, it remains unclear whether this momentary relationship is stable or changes over the first several years following surgery.

Background: Rice ECQ (eating and cooking quality) is an important determinant of rice consumption and market expansion. Therefore, improvement of ECQ is one of the primary goals in rice breeding. However, ECQ-related quantitative trait loci (QTL) have not yet been fully revealed.
