[THE OCTOBER MASSACRE AND IRON SWORDS WAR AS A TRIGGER FOR THE EMERGENCE OF EATING DISORDERS - A CASE SERIES].

INTRODUCTION: Eating disorders (EDs) are severe psychiatric disorders which entail substantial morbidity and mortality. Early detection and treatment are fundamental in determining prognosis. Exposure to traumatic events and acute stress are prominent risk factors for the emergence of EDs, while treatment delay may cause medical and psychiatric complications and lead to chronic illness. We describe a case series of two patients who recently presented to our center with anorexia nervosa, in which the latest events of the October massacre and the Iron Swords war were central in clinical deterioration and seeking treatment. We elaborate on the mechanisms in which the current emergency state may affect eating routines and lead to the development of EDs and emphasize the pivotal importance of efforts for early detection of new cases of EDs together with monitoring depression, anxiety, and post-traumatic symptoms. Given the heightened risk for the emergence of EDs at this time, early detection by health agents including parents, teachers, "resilience" centers and primary medicine teams is essential. We indicate that plans for early intervention that were prepared following the COVID-19 pandemic, may be implemented by family doctors and community-based dieticians to initiate therapy until treatment in a specialized ED center.

Pharmacological Studies in Eating Disorders: A Historical Review.

Eating disorders (EDs) are serious mental health conditions characterised by impaired eating behaviours and nutrition as well as disturbed body image, entailing considerable mortality and morbidity. Psychopharmacological medication is an important component in the treatment of EDs. In this review, we performed a historic analysis of pharmacotherapeutic research in EDs based on the scientific studies included in the recently published World Federation of Societies for Biological Psychiatry (WFSBP) guidelines for ED treatment. This analysis focuses on early approaches and trends in the methods of clinical pharmacological research in EDs, for example, the sample sizes of randomised controlled trials (RCTs). We found the development of psychopharmacological treatments for EDs followed advancements in psychiatric pharmacotherapy. However, the application of RCTs to the study of pharmacotherapy for EDs may be an impediment as limited participant numbers and inadequate research funding impede generalisability and statistical power. Moreover, current medication usage often deviates from guideline recommendations. In conclusion, the RCT model may not effectively capture the complexities of ED treatment, and funding limitations hinder research activity. Novel genetically/biologically based treatments are warranted. A more comprehensive understanding of EDs and individualised approaches should guide research and drug development for improved treatment outcomes.

Dropout from Mental Health Treatment Among Asylum-Seekers in Israel: A Retrospective Chart Study.

Dropout from psychiatric treatment and psychotherapy is common among asylum-seekers, even though they are at increased risk of emotional distress and psychiatric disorders. We aimed to define the associations between demographic and clinical variables and dropout among asylum-seekers in Israel. In this retrospective chart review we initially examined 271 files from Gesher (Bridge, in Hebrew), a government psychiatric clinic for asylum-seekers. All cases were considered eligible provided data were sufficient and asylum-seeker status could be ascertained. Of the 101 files included in the analysis, comparisons between patients who dropped out and patients who continued treatment were made, and logistic regression for dropout risk was conducted. In the study sample, 27 patients (26.7%) dropped out of treatment. Diagnosis of psychotic spectrum disorder and shorter time in Israel were significantly associated with dropout. Parenthood was significantly associated with dropout for men, but not for women. Defining factors associated with dropout and adherence to therapy for asylum-seekers may help improve ambulatory mental health services and the outcomes of treatment for this population.

Therapeutic alliance with psychotherapist versus dietician: a pilot study of eating disorder treatment in a multidisciplinary team during the COVID-19 pandemic.

Little is known about the therapeutic alliance (TA) formed with different professionals in multidisciplinary eating disorder (ED) treatment, particularly in the context of online treatment during the COVID-19 pandemic. We aimed to conduct a pilot study during the COVID-19 pandemic examining characteristics of patients' TA with their dieticians and psychotherapists, associations between patients' and therapists' views of the TA, and relationships between psychological characteristics and TAs. Sixty-three patients with EDs and their treating psychotherapists and dieticians were surveyed during the COVID-19 pandemic using the Working Alliance Inventory (WAI-S). Spearman correlation tests were used to examine associations between variables. Positive associations were found between the TAs examined. Concordance was stronger in patient-dietician dyads than in patient-psychotherapist dyads. Severe ED psychopathology was associated with weaker TA (bond subscale). General psychopathology was associated with weaker TA with the dietician (task subscale). Given that several differences were found between the TAs of treatment dyads, further longitudinal studies are needed to validate our pilot findings and to investigate multidisciplinary TAs and their impact on treatment outcomes in online ED treatment settings during the COVID-19 pandemic, as well as in other treatment settings (e.g., in-person settings). This study will contribute to a deeper understanding of the dynamics of TAs in multidisciplinary ED treatment and inform the development of more effective interventions.

Methylphenidate reduces orienting bias in healthy individuals.

BACKGROUND: Healthy individuals show subtle orienting bias, a phenomenon known as pseudoneglect, reflected in a tendency to direct greater attention toward one hemispace. Accumulating evidence indicates that this bias is an individual trait, and attention is preferentially directed contralaterally to the hemisphere with higher dopamine signaling. Administration of methylphenidate (MPH), a dopamine transporter inhibitor, was shown to normalize aberrant spatial attention bias in psychiatric and neurological patients, suggesting that the reduced orienting bias following administration of MPH reflects an asymmetric effect of the drug, increasing extracellular dopamine in the hemisphere with lower dopamine signaling. AIM: We predicted that, similarly to its effect on patients with brain pathology, MPH will reduce the orienting bias in healthy subjects. METHODS: To test this hypothesis, we examined the behavioral effects of a single dose (20 mg) of MPH on orienting bias in 36 healthy subjects (18 females) in a randomized, double-blind placebo-controlled, within-subject design, using the greyscales task, which has been shown to detect subtle attentional biases in both patients and healthy individuals. RESULTS/OUTCOMES: Results demonstrate that healthy individuals vary in both direction and magnitude of spatial orienting bias and show reduced magnitude of orienting bias following MPH administration, regardless of the initial direction of asymmetry. CONCLUSIONS/INTERPRETATIONS: Our findings reveal, for the first time in healthy subjects, that MPH decreases spatial orienting bias in an asymmetric manner. Given the well-documented association between orienting bias and asymmetric dopamine signaling, these findings also suggest that MPH might exert a possible asymmetric neural effect in the healthy brain.

Effects of non-invasive brain stimulation in children and young people with psychiatric disorders: a protocol for a systematic review.

BACKGROUND: Most psychiatric disorders have their onset in childhood or adolescence, and if not fully treated have the potential for causing life-long psycho-social and physical sequelae. Effective psychotherapeutic and medication treatments exist, but a significant proportion of children and young people do not make a full recovery. Thus, novel, safe, brain-based alternatives or adjuncts to conventional treatments are needed. Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are non-invasive brain stimulation (NIBS) techniques which have shown clinical benefits in adult psychiatric conditions. However, in children and young people their efficacy is not well established. The objective of this study will be to systematically evaluate the evidence on clinical effects of NIBS in children and young people with psychiatric disorders, assessing disorder-specific symptoms, mood and neurocognitive functions. METHODS: We designed and registered a study protocol for a systematic review. We will include randomised and non-randomised controlled trials and observational studies (e.g. cohort, case-control, case series) assessing the effects of NIBS in children and young people (aged ≤ 24 years old) for psychiatric disorders. The primary outcome will be reduction of disorder-specific symptoms. Secondary outcomes will include effects on mood and cognition. A comprehensive search from database inception onwards will be conducted in MEDLINE, EMBASE and PsycINFO. Grey literature will be identified through searching multiple clinical trial registries. Two reviewers will independently screen all citations, full-text articles and abstract data. The methodological quality of the studies will be appraised using appropriate tools. We will provide a narrative synthesis of the evidence and according to heterogeneity will conduct an appropriate meta-analysis. Additional analyses will be conducted to explore the potential sources of heterogeneity. DISCUSSION: This systematic review will provide a broad and comprehensive evaluation of the evidence on clinical effects of NIBS in children and young people with psychiatric disorders. Our findings will be reported according to the PRISMA guidelines and will be of interest to multiple audiences (including patients, researchers, healthcare professionals and policy-makers). Results will be published in a peer-reviewed journal. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019158957.

Repetitive transcranial magnetic stimulation treatment in severe, enduring anorexia nervosa: An open longer-term follow-up.

OBJECTIVE: This study assessed longer-term outcomes from a randomised controlled feasibility trial of 20 sessions of real versus sham high-frequency repetitive transcranial magnetic stimulation (rTMS) to the left dorsolateral prefrontal cortex in adults with severe, enduring anorexia nervosa (SE-AN). METHODS: Thirty participants who completed the original study protocol were invited to take part in an open follow-up (18-months post-randomisation), assessing body mass index (BMI), eating disorder (ED) symptoms and other psychopathology. RESULTS: Twenty-four participants (12 each originally allocated to real/sham) completed the 18-month follow-up. Ten of 12 participants who originally received sham treatment had real rTMS at some stage during the follow-up. A medium between-group effect size was seen for BMI change from baseline to 18-months, favouring those originally allocated to real rTMS. In this group at 18-months, five participants were weight recovered (BMI ≥18.5 kg/m2 ), compared with one participant in the original sham group. Both groups showed further improvement in ED symptoms during the follow-up. Effects on mood were largely maintained at follow-up, with catch-up effects in the original sham group. CONCLUSIONS: Findings suggest that rTMS treatment effects on mood are durable and that BMI and ED symptom improvements need time to emerge. Large-scale trials are needed.

The effect of methylphenidate on decision making in patients with borderline personality disorder and attention-deficit/hyperactivity disorder.

Impaired decision making in patients with borderline personality disorder (BPD) has been reported in several studies. Although methylphenidate (MPH) is known to ameliorate impaired decision making in patients with attention-deficit/hyperactivity disorder (ADHD), it has not yet been examined in patients with BPD. We therefore assessed the efficacy of a single dose of MPH on cognitive functions and decision making in patients with BPD. Twenty-two patients diagnosed with BPD participated in the study. The study was a randomized, double-blind placebo-controlled, random block order cross-over trial. Patients participated in two sessions and performed the Test of Variables of Attention, a digit-span test, and the computerized Iowa Gambling Task, after they had been administered either the MPH or a placebo. ADHD symptoms were assessed using the Adult ADHD Self-Report Scale-18. Lower scores on the inattention symptoms scale were associated with a greater improvement in decision making following the administration of MPH when compared with improvements in patients with higher ADHD scores [F(1,17)=5.63, P=0.030]. We conclude that MPH may improve decision making in patients with BPD, although this effect is mediated by the level of ADHD symptoms. Further studies are needed to assess whether a prolonged beneficial effect of MPH on decision making in patients with BPD might also be present in 'real life'.
