Summary: This systematic review found a relationship between eating disorders, particularly bulimia nervosa, and dental erosion. Individuals with bulimia nervosa were over 10 times more likely to experience tooth erosion, and self-induced vomiting increased the odds of tooth erosion by over 16 times.

Summary: The validity of diagnoses in the Swedish National Patient Register (NPR) is crucial for supporting research and policy recommendations. A comparison with the integrated National Quality Registers (QR) showed that the ED diagnoses in NPR have acceptable validity, providing valuable data for research purposes.

Summary: Research on Orthorexia nervosa (ON) is divided, with some studies suggesting it may fit the full-syndrome DSM-5 ED, while others propose that ON and DSM-5 EDs may co-occur. Only a few studies have suggested a relationship between ON and OCD. Currently, the clinical significance of ON and its relationship with EDs and OCD remains complicated and unclear, indicating a need for future research on the possible clinical course of ON.

Summary: The associations between eating disorders (EDs) and schizophrenia have been recognized, and familial liability to schizophrenia in individuals with anorexia nervosa (AN) reveals distinct patterns of clinical outcomes. This study investigates the influence of schizophrenia genetic liability among individuals with EDs, finding that higher schizophrenia polygenic risk scores (PRS) are significantly associated with increased risk of major depressive disorder (MDD) and substance abuse disorder (SUD). Additionally, higher schizophrenia PRS is related to earlier age at first ED symptom, higher ED symptom scores, and increased risk of MDD and SUD.

Summary: This study investigated why women decline specialized ED treatment and found that they believed treatment only focused on nutritional rehabilitation and failed to address their self-identified needs. Women reported that treatment was characterized by rigid standard procedures that could not be adapted to their individual situations and preferences. They felt therapists failed to listen to them, resulting in them feeling deprived of their identity.

Summary: In this meta-analysis of 35 papers, we found that receiving a higher level of care, having psychiatric comorbidity, and higher severity of ED psychopathology were associated with a higher likelihood of relapse in eating disorders. Conversely, higher leptin levels, higher meal energy density/variety, higher motivation for change, higher body mass index/weight/body fat, better response to treatment, anorexia nervosa-restricting subtype diagnosis, and older age of ED onset were associated with a lower likelihood of relapse. Various moderators were also identified.

Summary: This study examined the impact of the Covid-19 pandemic on child eating disorder hospitalizations in Quebec, Canada. The findings revealed an increase in hospitalization rates for eating disorders, particularly during the first and second waves of the pandemic. Girls aged 10-19 were most affected, but boys and individuals from different socioeconomic backgrounds were also impacted.

Summary: Assessing acute medical stability is important in patients with eating disorders, but attention should also be paid to the age-related consequences of malnutrition. Early and aggressive weight restoration is crucial for preventing long-term, potentially irreversible medical complications like linear growth impairment.

Summary: A study of 61 hospitalized ED patients indicates that participating in a post-hospitalization daycare program may improve the 1-year follow-up outcomes for patients, with more achievers of remission. However, patients who do not complete daycare treatment can also maintain a normal BMI one year later. There were no significant differences between the two groups in terms of social functioning, depression, anxiety, and other aspects.

Summary: Research on stigmatization in eating disorders has shown that individuals with anorexia nervosa, bulimia nervosa, and binge eating disorder face stereotypes, prejudices, and discrimination, which are influenced by demographic factors like age, gender, and income level. This stigma has negative effects on individuals' eating disorders, psychological wellbeing, and treatment-seeking behavior, highlighting the need for further research and prevention efforts.

Summary: This study compared traditional logistic regression models with two machine learning approaches to predict eating disorder onset and differential diagnoses. The results showed that all three approaches had satisfactory predictive accuracy, with the machine learning methods producing more parsimonious models. The study also found that different risk factors varied depending on the specific eating disorder classification.

Summary: The COVID-19 lockdown has significantly impacted patients with eating disorders (ED), with binge eating disorder (BED) patients experiencing the highest impact on weight and ED symptoms. Other specified feeding and eating disorders (OFSED) patients showed greater deterioration in general psychological functioning. Asian and younger individuals appeared to be more resilient.

Summary: Research suggests a link between anorexia nervosa and autism spectrum disorder, but differences exist in social attention. Autistic individuals showed reduced attention to faces compared to controls, while individuals with anorexia did not differ significantly in their attention to faces. Social motivation levels did not predict attention to faces in either group.

Summary: This study explored the definitions of recovery from an eating disorder (ED) from the perspective of individuals who have experienced ED themselves. The findings revealed similarities between the definitions provided by patients and those used by clinicians and researchers, while also highlighting the ongoing challenges in the recovery process. The study underscores the importance of continued support post-weight restoration to facilitate long-term successful recovery for individuals with ED.

Summary: Only one clinical pathway of treatment adaptations (the 'PEACE' pathway) was identified in Review 1 with early evidence of cost-savings and favourable treatment outcomes. ASC characteristics were shown in Review 2 to have no direct impact on physical outcomes or ED symptoms, but could be associated with higher rates of comorbidities and greater use of intensive ED treatment. Additionally, patients with ASC characteristics may benefit more from individual sessions, rather than group sessions.

Summary: The study revealed that rumination and non-acceptance of emotions are most closely associated with eating disorder psychopathology. Additionally, the associations between different emotion regulation strategies and symptomatology were weaker among patients with low BMI, suggesting a complex relationship between ED behaviors and emotion regulation. The findings call for interventions targeting emotion regulation, specifically rumination and difficulties accepting emotions, in the treatment of eating disorders.

Summary: This article systematically reviews randomized controlled trials (RCTs) evaluating psychotherapeutic interventions for anorexia nervosa (AN) and examines how unwanted events were defined, monitored, and reported. It found that there is a lack of consistent definitions and clear causality, making it difficult to distinguish between unwanted events and adverse events caused by the interventions. The review also highlights the challenge of defining unwanted events in studies with different populations and goals.

Summary: Avoidant Restrictive Food Intake Disorder (ARFID) is a serious eating disorder with little research on best practices, especially among adults. When ARFID coexists with autism, treatment options become further complicated. This case study discusses the treatment of an autistic woman with ARFID in an inpatient eating disorder setting. Food exposure and trials were used to increase food variety and nutrition, leading to promising results in weight and food repertoire improvement. Although results may not apply to a wider population, this approach could be beneficial for individuals with ARFID and autism.
