A new theoretical approach of cognitive information processing in eating disorders is introduced. It is based on the system theory with a view on health psychology. We are going to emphasize the deviations in the self-concept, the role of procedural memory in body image disturbance and the content of working memory supporting the appearance of cognitive dysfunctions in eating disorders. Despite the long-standing interest in eating disorders a coherent body of empirically supported knowledge that can be used to direct clinical practice, has yet to emerge. Although there are many possible causes of this limited progress, one important source of difficulty is that research completed to date has tended to be based on clinical models of psychopathology lacking a sound theoretical framework. The complex multidimensional nature of the model shows several possibilities of prevention and intervention in eating disorders.

The progress in the field of clinical staging for mental disorders within the last decade: an updated systematic review.

Introduction: Clinical staging aims to refine psychiatric diagnosis by describing mental disorders on a continuum of disorder progression, with the pragmatic goal of improved treatment planning and outcome prediction. The first systematic review on this topic, published a decade ago, included 78 papers, and identified separate staging models for schizophrenia, unipolar depression, bipolar disorder, panic disorder, substance use disorder, anorexia, and bulimia nervosa. The current review updates this review by including new proposals for staging models and by systematically reviewing research based upon full or partial staging models since 2012.

Is there anything left to eat? A lived experience insight of following a restrictive type 1 diabetes and dialysis diet.
Expert Rev Endocrinol Metab

Faculty of Health and Social Sciences, Bournemouth University, UK.
Objectives: Chronic kidney disease has a global morbidity burden of >10%, with diabetes being a major cause. Nutrition therapy is vital in managing both chronic conditions, yet CKD dietary guidelines contradict healthy eating advice, and can result in major psychological and social burdens. Few studies investigate the patient's experience of being placed on such a restrictive diet.

Department of Psychiatry, Ankara University, Ankara, Turkey.
Objectives: This study compared cognitive flexibility (CF) and emotion recognition (ER) in adolescents with eating disorders (ED) to a healthy group.
Methods: Forty healthy individuals aged 12-18 years with no psychiatric diagnosis and 46 patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED) according to DSM-5 criteria participated. CF was assessed using the Cognitive Flexibility Scale (CFS), Stroop Test, and Berg Card Sorting Test (BCST), while ER was evaluated using the test of perception of affect via nonverbal cues.

The diagnosis of autism is currently based on the developmental history, direct observation of behavior, and reported symptoms, supplemented by rating scales/interviews/structured observational evaluations-which is influenced by the clinician's knowledge and experience-with no established diagnostic biomarkers. A growing body of research has been conducted over the past decades to improve diagnostic accuracy. Here, we provide an overview of the current diagnostic assessment process as well as of recent and ongoing developments to support diagnosis in terms of genetic evaluation, telemedicine, digital technologies, use of machine learning/artificial intelligence, and research on candidate diagnostic biomarkers.
