Binge Eating Disorders
0 Views •
2025
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Dietary fat content influences both energy intake and body fat composition in mammals. By examining rats’ preference for high fat food in a series of choice experiments, it is possible to test genetic differences and pharmacological interventions on their preference for high fat food.

Subjects eat food from a plate placed on a scale connected to a computer that records the weight loss of the plate during the meal. Feedback on the computer screen allows the subject to adapt her/his eating behavior to reference curves thus normalizing body weight.

Diagnosing eating disorders in healthcare is challenging. Therefore, the present protocol develops an algorithm based on 949 patient responses to a questionnaire, with the diagnosis displayed on an easy-to-use web-based interface. This system facilitates the accurate diagnosis of eating disorders while excluding those believed to have an eating disorder.

Invertebrate Lifespan Quantification

Many animals naturally stop growing upon reaching adulthood, after which they undergo aging or "senescence" until dying. The amount of time between an organism\'s birth and death is called its lifespan, which can be influenced by various biological and environmental factors. By exposing organisms to different growth conditions, scientists can better understand the factors affecting lifespan. Flies and worms are ideal organisms to perform such experiments, given their short generation time and...
FAQs
Reliable measurement depends on separating EAT from adjacent cardiac and pericardial structures on the selected images. CT or MRI provides the image contrast, while segmentation software traces the relevant tissue and computes its volume. This division between image acquisition and computational delineation matters because the final value reflects both the visible anatomy and how consistently boundaries are identified.
Volume describes how much EAT is present, whereas attenuation or other compositional features may add information about what the tissue looks like on imaging. These measurements can therefore complement size-based assessment rather than replace it. In cardiovascular studies, that broader characterization supports investigation of links between local adipose tissue, inflammation, coronary artery disease risk, and atrial fibrillation.
EAT measurements are relevant because the tissue lies directly around the heart, making its quantity and imaging characteristics useful markers of local cardiac-adipose biology. Reported associations include obesity-related cardiac remodeling, inflammation, coronary artery disease risk, and atrial fibrillation. The measurement can therefore connect systemic metabolic status with structural and disease-related features observed in cardiovascular medicine.
Standardized EAT quantification is important when values are compared across patients, studies, or interventions. Consistent imaging interpretation and segmentation can make changes in measured volume or composition easier to attribute to biological differences rather than measurement practices. This consistency may strengthen risk stratification and support more precise evaluation of metabolic or cardiovascular interventions, especially in research settings.
A typical workflow begins with cardiac CT or MRI, followed by identification of the tissue compartment between the myocardium and visceral pericardium. Software then segments that region and calculates its volume; selected analyses may also record attenuation or other compositional features. The resulting dataset can characterize both the amount of EAT and, when assessed, additional imaging properties.
In medicine, these measurements can characterize patients or cohorts in studies of obesity-related cardiac remodeling, inflammation, coronary artery disease risk, and atrial fibrillation. They also provide a quantitative endpoint for research examining how adipose tissue near the heart may affect cardiac health. When applied consistently, measurements can help evaluate the effects of metabolic or cardiovascular interventions.
