Orthorexia nervosa and eating disorder behaviors: A systematic review of the literature.

Appetite 2022 Jun 21:106134. Epub 2022 Jun 21.

University of South Alabama, Department of Psychology, Mobile, AL, 36688, USA.

Background: Orthorexia nervosa (ON) involves obsessive thoughts about healthy eating and distress related to this obsession. There is still dispute over whether ON should be considered on the obsessive-compulsive spectrum, the eating disorder (ED) spectrum, or as its own disorder. Based on current research, orthorexic behaviors seem to be closely related to eating disorder behaviors. Read More

Effects of Music Therapy in the Reduction of Pre-Meal Anxiety in Patients Suffering from Anorexia Nervosa.

Brain Sci 2022 Jun 19;12(6). Epub 2022 Jun 19.

The Giovanni Ferrari Music Therapy School, 35100 Padua, Italy.

Literature reviews appear to indicate that Music Therapy (MT) may instil a sense of empowerment and generate feelings of renewed self-confidence, distracting subjects who follow this type of intervention from negative thoughts and, generally, helping patients suffering from Anorexia Nervosa (AN) to redevelop or rediscover their identity. The purpose of the study reported in this paper is to investigate whether MT proposed before an evening meal is capable of decreasing pre-meal anxiety in adolescents suffering from AN who follow the Day-hospital Treatment Programme at the San Bortolo Hospital of Vicenza (Italy). A total of 24 patients participated voluntarily in once-weekly sessions of group-based MT conducted by a qualified music therapist over a period of six months. Read More

Eating Disorders and Disordered Eating Behaviors in Cystic Fibrosis: A Neglected Issue.

Children (Basel) 2022 Jun 18;9(6). Epub 2022 Jun 18.

Department of Public Health Policy, School of Public Health, University of West Attica, Athens University Campus, 196 Alexandra's Avenue, 11521 Athens, Greece.

As with the majority of chronic diseases having specific nutrition recommendations, in cystic fibrosis (CF), the emphasis placed on patients regarding their diet and ideal body weight status often increases the risk of developing disordered eating behaviors and by inference, eating disorders (EDs). Body weight appears to be an important concern for patients with CF, with many patients struggling to lose weight. Between sexes, women appear more preoccupied with dieting compared to men, but exhibit a better body image, mainly due to their preference for a lower weight. Read More

Atypical Anorexia in Youth: Cautiously Bridging the Treatment Gap.

Children (Basel) 2022 Jun 5;9(6). Epub 2022 Jun 5.

Division of Adolescent and Young Adult Medicine, Boston Children's Hospital, Boston, MA 02115, USA.

Atypical anorexia nervosa (AAN) is a restrictive eating disorder (ED) that describes individuals who may be normal weighted or overweight; many have a premorbid history of obesity. Pediatric care providers are trained to identify and provide best practices for youth with pediatric obesity; however, most pediatric care providers are not trained to assess and treat restrictive EDs which typically present in youth aged 10 and 14 years. Although individuals with AAN may appear to be within a 'healthy weight', many experience malnutrition, psychological symptoms, and severe physiological complications after weight loss. Read More

Distinguishing delusional beliefs from overvalued ideas in Anorexia Nervosa: An exploratory pilot study.

J Eat Disord 2022 Jun 23;10(1):85. Epub 2022 Jun 23.

School of Psychology, Faculty of Science, University of Sydney, Sydney, NSW, Australia.

Background: Characterised by the belief that more weight needs to be lost-despite emaciation, failing organs, medical instability and prospect of death-Anorexia Nervosa (AN) is a condition in which irrational, and highly-skewed, beliefs can be of delusional intensity. However, the nexus between delusion and rational awareness and how this is related to body image acceptance and perception has yet to be examined in AN. The current study aims to investigate the relationship between body dissatisfaction and beliefs of delusional intensity in an adult AN inpatient sample. Read More

Severity Level and Duration of Energy Deficit in Mice Affect Bone Phenotype and Bone Marrow Stromal Cell Differentiation Capacity.

Front Endocrinol (Lausanne) 2022 6;13:880503. Epub 2022 Jun 6.

MAB Lab ULR4490, Univ Littoral Côte d'Opale, Boulogne-sur-Mer, France.

Anorexia nervosa is known to induce changes in bone parameters and an increase in bone marrow adiposity (BMA) that depend on the duration and seriousness of the disease. Previous studies have found that bone loss is associated with BMA accumulation. Sirtuin of type 1 (Sirt1), a histone deacetylase that is partly regulated by energy balance, was shown to have pro-osteoblastogenic and anti-adipogenic effects. Read More

Anorexia nervosa and the gastrointestinal tract.

Frontline Gastroenterol 2022 20;13(4):316-324. Epub 2021 Aug 20.

Gastroenterology, Stockport NHS Foundation Trust, Stockport, UK.

Anorexia nervosa (AN) is a complex eating disorder associated with a high morbidity and mortality, however, there is a lack of dedicated training for healthcare professionals outside of mental health specialities. There has been a reported increase in acute admissions of patients with AN, which may have been precipitated by the isolation and loss of support networks created by the COVID-19 pandemic. The purpose of this review is to highlight that AN can present with a wide variety of signs and symptoms relating to both the hollow and solid organs of the gastrointestinal (GI) tract some of which may even be life threatening.

Trauma exposure and eating disorders: Results from a United States nationally representative sample.

Int J Eat Disord 2022 Jun 19. Epub 2022 Jun 19.

San Diego State University/University of California San Diego Joint Doctoral Program in Clinical Psychology, San Diego, California.

Objective: Sexual assault, child abuse, and combat have been linked to eating disorders (EDs). However, noninterpersonal trauma is relatively understudied, and therefore it is unknown whether noninterpersonal trauma is associated with EDs. Furthermore, most previous studies do not account for multiple trauma exposures, or the relative association of traumatic events with EDs in the same statistical model. Read More

Large-scale exploration of whole-brain structural connectivity in anorexia nervosa: alterations in the connectivity of frontal and subcortical networks.

Biol Psychiatry Cogn Neurosci Neuroimaging 2022 Jun 14. Epub 2022 Jun 14.

Department of Psychiatry, Duke University, Durham, NC, USA.

Background: Anorexia nervosa (AN) is characterized by disturbances in cognition and behavior surrounding eating and weight. The severity of AN combined with the absence of localized brain abnormalities suggests distributed, systemic underpinnings that may be identified using diffusion-weighted MRI (dMRI) and tractography to reconstruct white matter pathways.

Methods: DMRI data acquired from female patients with AN (n = 147) and female healthy controls (HC; n = 119), aged 12-40 years, were combined across five studies. Read More

Defining Autonomy in Psychiatry.

Front Psychiatry 2022 31;13:801415. Epub 2022 May 31.

Department of Psychiatry, Amsterdam UMC, Amsterdam, Netherlands.

Mental illness undermines a patient's personal autonomy: the capacities of a person that enables them to live a meaningful life of their own making. So far there has been very little attention given to personal autonomy within psychiatry. This is unfortunate as personal autonomy is disturbed in different ways in psychiatric disorders, and understanding how autonomy is affected by mental illness is crucial for differential diagnosis and treatment, and also for understanding personal recovery.

Treatment response in children and adolescents with anorexia nervosa: a naturalistic, case-control study.

Eat Weight Disord 2022 Jun 15. Epub 2022 Jun 15.

IRCCS Istituto delle Scienze Neurologiche di Bologna, Centro Regionale per i Disturbi della Nutrizione e dell'Alimentazione in Età Evolutiva, UO Neuropsichiatria dell'Età Pediatrica, Bologna, Italy.

Purpose: Although a few recent articles describe adults with treatment-resistant anorexia nervosa (TR-AN), no study addresses the specific features of subjects not responding to treatment in the developmental age. This study reports on the clinical and psychopathological variables that distinguish children and adolescents who did not respond to treatment (here "TR-AN") from good-outcome controls, in a multidisciplinary hospital treatment setting.

Methods: Naturalistic, case-control study conducted on individuals showing lack of response to treatment and good-outcome controls. Read More
