Anorexia Nervosa and Comorbidities Linking Autism
No full textAnorexia Nervosa (AN) and Autism Spectrum Disorder (ASD) are two mental
health conditions sharing a series of clinical features. Epidemiological studies
have documented that subjects with AN may present ASD and ASD traits more
frequently than the general population. Specific studies have discussed the use of
psychodiagnostics tools to investigate ASD traits in individuals with AN. Recent research has reported common neuropsychological (i.e., deficits in “Theory of
Mind”) and psychopathological (i.e., alexithymia) traits between the two conditions.
Finally, ASD traits may impact the interventions to treat AN. This chapter
examines the recent literature reporting on the link between AN and ASD, and
discusses the implications of this link for the development of new screening and
treatment protocols
The involvement of the adrenergic system in feeding and eating disorders. A systematic review
No full textBackgroundAdrenergic dysregulation has been proposed as a possible underlying mechanism in feeding and eating disorders (FED). This review aims to synthesise the current evidence on the role of adrenergic dysregulation in the pathogenesis and management of FED.MethodsA systematic review was conducted in MEDLINE, Cochrane Library, and Clinicaltrials.gov. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was adopted. Preclinical, clinical, and pharmacological studies assessing the adrenergic system in FED were included.ResultsThirty-one out of 1415 recognised studies were included. Preclinically, studies on adrenaline's anorectic impact, receptor subtypes, and effects on hepatic function in rats show that catecholamine anorexia is primarily alpha-adrenergic, whereas beta-adrenergic anorexia can be obtained only after puberty, implying an impact of sexual hormones. Clinically, catecholamine levels may be higher in FED patients than in healthy controls (HC). Individuals with anorexia nervosa (AN) may show higher epinephrine-induced platelet aggregability response than HC. Pharmacological trials suggest that the alpha-2-adrenergic medication clonidine may not lower AN symptoms, but agents regulating the adrenaline-noradrenaline neurotransmission (bupropion, reboxetine, duloxetine, sibutramine) have been found to improve binge eating symptoms.ConclusionAdrenergic dysregulation may be involved in the pathophysiology of FED. More research is needed to comprehend underlying mechanisms and treatment implications
The role of risperidone in the treatment of children and adolescents with anorexia nervosa
No full textBackground: Current Diagnostic and Statistical Manual of Mental Disorders (DSM)-5-based research provides limited data on the use of risperidone on children and adolescents with anorexia nervosa (AN) mainly in small-sample/case report studies. Aim: To report the use of risperidone in a group of children and adolescents with feeding and eating disorders, specifically with AN. Methods: Observational, naturalistic study. Psychopathology was assessed with Eating Disorders Inventory-3, Beck's Depression Inventory-II, and Symptom Checklist-90-R. Data were reported for the whole sample, for patients treated with risperidone, and finally compared between patients with AN treated with risperidone and those receiving no atypical antipsychotics. Potential differences in admission-discharge changes in body mass index (BMI) and psychopathology were assessed with analyses of covariance corrected for baseline measures. Kaplan-Meier analyses were conducted to assess retention rates of risperidone (at 3 months and 1 year) and rates of rehospitalization on 1-year follow-up. Results: The study enrolled 120 patients with AN (42 treated with risperidone). Risperidone was used for 116.7 (& PLUSMN;122.8) days (total exposure = 3979 days) and well-tolerated (nausea, asthenia in one case). No significantly different admission-discharge improvements for BMI or psychopathology were documented for patients treated with risperidone. Risperidone showed a 3-month retention rate of 50.0% (1 year: 9.5%) and was discontinued mainly for the resolution of target symptoms. Cumulative freedom from rehospitalization at 12 months was comparable for treated and untreated patients (hazard ratio = 1.088; Log-rank p = 0.908). Conclusions: This study reports real-life evidence of the use of risperidone in AN children and adolescents in the widest described sample so far. Longitudinal research should assess long-term prognostic factors and tolerability
Avoidant-restrictive food intake disorder in a male patient with Goldenhar syndrome
Full text linkBACKGROUND: Goldenhar syndrome (GS) is a rare congenital condition characterized by the underdevelopment of structures deriving from the first and second branchial arches. Clinical phenotype might encompass extra-craniofacial abnormalities, and patients may experience neuropsychiatric disorders with a higher prevalence than healthy controls. To the best of our knowledge, an association between GS and Feeding and Eating Disorders (FED) has never been reported in the literature. CASE REPORT: A 15-year-old boy with GS was referred to our outpatient clinic due to severe underweight (BMI of 12.7 kg/m(2)) and food intake disorder with avoidant restrictive features. After a diagnosis of avoidant-restrictive food intake disorder (ARFID) was made, an inpatient multidisciplinary intervention and outpatient follow-up program were provided, which resulted in the improvement of the boy’s weight and FED psychopathology. CONCLUSIONS: The current report describes the first case of a young male with GS and ARFID. We suggest that ARFID may present itself as part of the spectrum of neuropsychiatric disorders associated with the syndrome; since traumatic experiences and gastrointestinal discomfort play a pivotal role in the development of ARFID among children, attention should be paid to those affected by GS that involves crucial structures in the swallowing process. Further literature evidence will help portray the complex relationship between ARFID and GS more precisely. LEVEL OF EVIDENCE: Level V, case report
Barriers and facilitators affecting treatment uptake behaviours for patients with eating disorders: A systematic review synthesising patient, caregiver and clinician perspectives
Full text linkObjectiveA significant treatment gap exists between persons affected by eating disorders (ED), and those engaging with treatment services. This systematic review aims to provide a thorough understanding of the barriers and facilitators affecting eating disorder treatment engagement, including a synthesis of the perspectives of patients, caregivers and healthcare professionals. MethodThis systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were retrieved from three databases (PubMed, PsycInfo, Web of Science) and were screened and assessed independently by two raters. A thematic analysis was completed to determine the key barriers and facilitators reported by the included studies. ResultsA total of 73 studies were included. From these studies, 12 barriers and 13 facilitators were identified. Patients reported stigma, shame and guilt as the most prominent barrier affecting their engagement with treatment services. Meanwhile, caregivers and healthcare professionals reported a lack of eating disorder knowledge of clinicians as the most important barrier. Positive social support was cited as the most prominent facilitator to promote help-seeking. DiscussionPatients, caregivers and healthcare professionals experience a variety of barriers and facilitators to treatment uptake for ED. Interventions addressing barriers and facilitators could increase treatment engagement, including anti-stigma campaigns and positive peer-support interventions
Food and Development: Children and Adolescents with Neurodevelopmental and Comorbid Eating Disorders—A Case Series
Full text linkThe impact of psychiatric comorbidities in the diagnosis and treatment of feeding and eating disorders (FEDs) represents an emerging research topic. The current literature, nonetheless, lacks studies investigating the developmental paths of individuals with FEDs and comorbid neurodevelopmental disorders (NDDs). Here, we report 11 cases of children and adolescents with comorbid FEDs and NDDs, as assessed along the neuropsychological, psychopathological, and nutritional developmental pathways. The onset of FED-related psychopathology was preceded, sometimes undiagnosed, by altered neurodevelopmental features leading to specific NDD diagnoses (autism spectrum disorder—ASD; attention-deficit/hyperactivity disorder—ADHD; specific learning disorder—SLD). NDDs appeared to influence the diagnoses and treatments of FEDs, frequently with an impact on socio-relational and emotional premorbid features, and on the possibility to receive and attend FED-targeted treatments. Further studies should longitudinally contribute to assessing the experiences of care and neurodevelopmental pathways of children with FEDs and specific NDD comorbidities
Status Epilepticus in Chromosomal Disorders Associated with Epilepsy: A Systematic Review
Full text linkStatus Epilepticus (SE) is a neurological emergency resulting from the failure of mechanisms of seizure termination or from the initiation of mechanisms that lead to prolonged seizures. The International League Against Epilepsy (ILAE) identified 13 chromosomal disorders associated with epilepsy (CDAE); data regarding SE occurrence in these patients is lacking. A systematic scoping review was conducted to outline current literature evidence about clinical features, treatments, and outcomes of SE in pediatric and adult patients with CDAE. A total of 373 studies were identified with the initial search; 65 of these were selected and regarded as SE in Angelman Syndrome (AS, n = 20), Ring 20 Syndrome (R20, n = 24), and other syndromes (n = 21). Non-convulsive status epilepticus (NCSE) is frequently observed in AS and R20. No specific, targeted therapies for SE in CDAE are available to date; anecdotal reports about SE treatment are described in the text, as well as various brief- and long-term outcomes. Further evidence is needed to precisely portray the clinical features, treatment options, and outcomes of SE in these patients
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
