Naturalistic symptom trajectories of atypical anorexia nervosa, anorexia nervosa, and bulimia nervosa in a prospective cohort study of United States college students.

Objective: Research on the natural course of symptoms of atypical anorexia nervosa (AN) relative to AN and bulimia nervosa (BN) is limited yet needed to inform nosology and improve understanding of atypical AN. This study aimed to 1) characterize trajectories of eating disorder and internalizing (anxiety, depression) symptoms in college students with and without a history of atypical AN, AN, and BN; and 2) compare sex and race/ethnicity distributions across groups.

Method: United States college students who participated in Spit for Science™, a prospective cohort study, were classified as having a history of atypical AN (n = 125), AN (n = 160), BN (n = 617), or as non-eating-disorder controls (NCs, n = 5876).

Deep-Learning-Based Antenna Alignment Prediction for Mobile Indoor Communication.

A significant innovation for future indoor wireless networks is the use of the mmWave frequency band. However, an important challenge comes from the restricted propagation conditions in this band, which necessitates the use of beamforming and associated beam management procedures, including, for instance, beam tracking or beam prediction. A possible solution to the beam management problem is to use artificial-intelligence-based procedures to learn the hidden spatial propagation patterns of the channel and to use this knowledge to predict the best beam directions.

Industrial Symbiosis for Sustainable Management of Meat Waste: The Case of Śmiłowo Eco-Industrial Park, Poland.

This study presents the developing process of the Śmiłowo Eco-Park, located in the Noteć valley region (Poland), is a part of the biggest Polish agri-food consortium, from its initial small waste management company to its final structure as an eco-industrial park using industrial symbiosis methods. The industrial symbiosis applied in the Eco-park promotes a business model which covers the whole life cycle of the products starting from the plant growing by animal feed preparation, livestock breeding, meat preparations, meat-bone meal production from animal waste, and the use of pig slurry as a fertilizer. The Eco-park model is presented in the form of a system of connected stream flows of materials and energy covering the full lifecycle of products, from cereal cultivation, through the production of industrial feed, and poultry and pig breeding for the production of meat products.

Modifying an Open Science Online Grocery for parents of youth with anorexia nervosa: A proof-of-concept study.

Objective: For youth with anorexia nervosa (AN), remission requires high caloric goals to achieve weight restoration, consumption of a wide variety of calorically dense foods, and reintroduction of eliminated foods. Family-based treatment (FBT), the gold-standard treatment for youth with AN, empowers parents to renourish their child and restore them to health; yet, parents often report struggling with shifting meal planning and grocery shopping behaviors to focus on nutritional rehabilitation and weight restoration.

Methods: This proof-of-concept study aimed to modify a simulated grocery store (Open Science Online Grocery [OSOG]) for parents of youth with AN and explore the acceptability and feasibility of its use as part of standard care.

Autistic characteristics in youth with anorexia nervosa before and after treatment.

Objective: Cognitive characteristics common to autistic individuals are often seen in adults with anorexia nervosa (AN), raising the question of whether autistic people and people with AN may share an endophenotype. We need to examine autistic characteristics during the early stages of AN to accurately parse true symptom co-occurrence from behavioural alterations due to prolonged illness.

Methods: We conducted a post-hoc analysis examining autistic characteristics in 59 youth with AN.

How Does Fasting Affect Cognition? An Updated Systematic Review (2013-2020).

Purpose Of Review: The goal of this review was to provide an update on the literature examining how voluntary, temporary abstention from eating impacts cognitive function.

Recent Findings: We evaluated peer-reviewed articles published between August 2013 and January 2021 that assessed adults, included a measure of cognitive functioning with neutral stimuli, and compared individuals in a fasted state to individuals in a fed state (either within- or between-subject designs). Nineteen articles (21 studies) met inclusion criteria.

Quantification of material recovery from meat waste incineration - An approach to an updated food waste hierarchy.

The meat industry generates a significant amount of hazardous waste, containing phosphorus, calcium, and other elements which could be the basis for other products. This work presents the results of research on the thermal utilisation of bone meat waste and the use of the ash thus obtained as a substitute for phosphorus raw materials. Material Flow Analysis was used to quantify and assess the option with the highest material productivity.

Starch Solutions Prepared under Different Conditions as Modifiers of Chitosan/Poly(aspartic acid)-Based Hydrogels.

Recently, there has been great interest in the application of polysaccharides in the preparation of diverse biomaterials which result from their biocompatibility, biodegradability and biological activity. In this work, the investigations on chitosan/poly(aspartic acid)-based hydrogels modified with starch were described. Firstly, a series of hydrogel matrices was prepared and investigated to characterize their swelling properties, structure via FT-IR spectroscopy, elasticity and tensile strength using the Brookfield texture analyzer as well as their impact on simulated physiological liquids.
