The bidirectional connection between family functioning and psychopathology: A network analysis in a large sample of adolescents with anorexia nervosa and their parents.

Family functioning is a risk and maintaining factor for anorexia nervosa (AN). This study aims to identify specific areas of family functioning according to adolescents and parental perspectives associated with eating and general psychological symptoms in people with AN. Four-hundred-forty-five adolescents with AN or atypical AN and their parents were enrolled. Adolescents completed the Eating Disorder Inventory-3, the Youth Self-Report questionnaire, and the Family Assessment Device (FAD). Their parents filled in the FAD. A network analysis was conducted including all subscales. The bridge function analysis was applied to identify the bridge nodes connecting each community constituted of family functioning perception with the communities of adolescents' eating and general psychological symptoms. Family communication was the node most strongly connecting fathers and mothers' perception of family functioning and adolescents' eating symptoms. Problem solving was the node with the highest bridge expected influence between mothers' family functioning and adolescents' general psychopathology. General functioning and problem solving were the bridge nodes between adolescents' view of family functioning and eating and general psychopathology. Maturity fear, interpersonal insecurity, and interpersonal alienation were the bridge nodes between adolescents' eating symptoms and mothers, fathers, and adolescents' family functioning communities respectively. Family members must be involved in the therapeutic process to improve family communication and problem solving diverting their attention toward emotional needs and interpersonal difficulties of adolescents with AN. Developing autonomy and independence from parents and building trustworthy relationships with peers may be favored by improving familiar dynamics and may contribute to prevent the maintenance of AN.

Outcomes in people with eating disorders: a transdiagnostic and disorder-specific systematic review, meta-analysis and multivariable meta-regression analysis.

Eating disorders (EDs) are known to be associated with high mortality and often chronic and severe course, but a recent comprehensive systematic review of their outcomes is currently missing. In the present systematic review and meta-analysis, we examined cohort studies and clinical trials published between 1980 and 2021 that reported, for DSM/ICD-defined EDs, overall ED outcomes (i.e., recovery, improvement and relapse, all-cause and ED-related hospitalization, and chronicity); the same outcomes related to purging, binge eating and body weight status; as well as mortality. We included 415 studies (N=88,372, mean age: 25.7±6.9 years, females: 72.4%, mean follow-up: 38.3±76.5 months), conducted in persons with anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), other specified feeding and eating disorders (OSFED), and/or mixed EDs, from all continents except Africa. In all EDs pooled together, overall recovery occurred in 46% of patients (95% CI: 44-49, n=283, mean follow-up: 44.9±62.8 months, no significant ED-group difference). The recovery rate was 42% at <2 years, 43% at 2 to <4 years, 54% at 4 to <6 years, 59% at 6 to <8 years, 64% at 8 to <10 years, and 67% at ≥10 years. Overall chronicity occurred in 25% of patients (95% CI: 23-29, n=170, mean follow-up: 59.3±71.2 months, no significant ED-group difference). The chronicity rate was 33% at <2 years, 40% at 2 to <4 years, 23% at 4 to <6 years, 25% at 6 to <8 years, 12% at 8 to <10 years, and 18% at ≥10 years. Mortality occurred in 0.4% of patients (95% CI: 0.2-0.7, n=214, mean follow-up: 72.2±117.7 months, no significant ED-group difference). Considering observational studies, the mortality rate was 5.2 deaths/1,000 person-years (95% CI: 4.4-6.1, n=167, mean follow-up: 88.7±120.5 months; significant difference among EDs: p<0.01, range: from 8.2 for mixed ED to 3.4 for BN). Hospitalization occurred in 26% of patients (95% CI: 18-36, n=18, mean follow-up: 43.2±41.6 months; significant difference among EDs: p<0.001, range: from 32% for AN to 4% for BN). Regarding diagnostic migration, 8% of patients with AN migrated to BN and 16% to OSFED; 2% of patients with BN migrated to AN, 5% to BED, and 19% to OSFED; 9% of patients with BED migrated to BN and 19% to OSFED; 7% of patients with OSFED migrated to AN and 10% to BN. Children/adolescents had more favorable outcomes across and within EDs than adults. Self-injurious behaviors were associated with lower recovery rates in pooled EDs. A higher socio-demographic index moderated lower recovery and higher chronicity in AN across countries. Specific treatments associated with higher recovery rates were family-based therapy, cognitive-behavioral therapy (CBT), psychodynamic therapy, and nutritional interventions for AN; self-help, CBT, dialectical behavioral therapy (DBT), psychodynamic therapy, nutritional and pharmacological treatments for BN; CBT, nutritional and pharmacological interventions, and DBT for BED; and CBT and psychodynamic therapy for OSFED. In AN, pharmacological treatment was associated with lower recovery, and waiting list with higher mortality. These results should inform future research, clinical practice and health service organization for persons with EDs.

Childhood maltreatment, alexithymia and eating disorder psychopathology: A mediation model.

BACKGROUND: The relationship between childhood maltreatment and eating disorder psychopathology has been under-investigated. OBJECTIVE: The purpose of this study was to investigate the role of alexithymia in mediating the relationship between childhood maltreatment experiences and eating disorder (ED) symptoms. PARTICIPANTS AND SETTING: One-hundred-forty-three women with anorexia nervosa, 110 women with bulimia nervosa and 108 healthy women filled in the Eating Disorder Inventory-2, the Childhood Trauma Questionnaire and the Toronto Alexithymia Scale-20 (TAS-20). METHODS: A mediator path model including childhood trauma types as predictors, the subscales of the TAS-20 as mediators and ED specific symptoms as dependent variables was conducted in individuals with EDs and in healthy women. RESULTS: In women with EDs emotional abuse was directly associated with body dissatisfaction and was associated to drive to thinness, bulimia and body dissatisfaction through the mediation of difficulties to identify emotions. In healthy women, physical neglect was directly associated to drive to thinness and bulimia, but no significant mediation effect through alexithymia emerged. CONCLUSION: Impaired emotion recognition mediates the association between childhood emotional abuse and ED symptoms. Individuals with early emotional abuse may experience ED symptoms to manage confused emotional perceptions. Improving emotional understanding and acceptance may be a treatment target in early maltreated individuals with EDs.

Association between childhood maltreatment and cortical folding in women with eating disorders.

Childhood maltreatment (CM) is associated with distinct clinical and biological characteristics in people with eating disorders (EDs). The measurement of local gyrification index (lGI) may help to better characterize the impact of CM on cortical structure. Thus, the present study investigated the association of CM with lGI in women with EDs. Twenty-six women with anorexia nervosa (AN) and 24 with bulimia nervosa (BN) underwent a 3T MRI scan. All participants filled in the Childhood Trauma Questionnaire. All neuroimaging data were processed by FreeSurfer. LGI maps underwent a general linear model to evaluate differences between groups with or without CM. People with AN and BN were merged together. Based on the Childhood Trauma Questionnaire cutoff scores, 24 participants were identified as maltreated and 26 as non-maltreated. Maltreated people with EDs showed a significantly lower lGI in the left middle temporal gyrus compared with non-maltreated people, whereas no differences emerged in the right hemisphere between groups. The present study showed that in people with EDs, CM is associated with reduced cortical folding in the left middle temporal gyrus, an area that could be involved in ED psychopathology. This finding corroborates the hypothesis of a 'maltreated ecophenotype', which argues that CM may allow to biologically, other than clinically, distinguish individuals with the same psychiatric disorder.

Treatment of Eating Disorders: a systematic meta-review of meta-analyses and network meta-analyses. NEUROSCI BIOBEHAV REV 21(1) XXX-XXX, 2022.- Treatment efficacy for eating disorders (EDs) is modest and guidelines differ. We summarized findings/quality of (network) meta-analyses (N)MA of randomized controlled trials (RCTs) in EDs. Systematic meta-review ((N)MA of RCTs, ED, active/inactive control), using (anorexia or bulimia or eating disorder) AND (meta-analy*) in PubMed/PsycINFO/Cochrane database up to December 15th, 2020. Standardized mean difference, odds/risk ratio vs control were summarized at end of treatment and follow-up. Interventions involving family (family-based therapy, FBT) outperformed active control in adults/adolescents with anorexia nervosa (AN), and in adolescents with bulimia nervosa (BN). In adults with BN, individual cognitive behavioural therapy (CBT)-ED had the broadest efficacy versus active control; also, antidepressants outperformed active. In mixed age groups with binge-eating disorder (BED), psychotherapy, and lisdexamfetamine outperformed active control. Antidepressants, stimulants outperformed placebo, despite lower acceptability, as did CBT-ED versus waitlist/no treatment. Family-based therapy is effective in AN and BN (adolescents). CBT-ED has the largest efficacy in BN (adults), followed by antidepressants, as well as psychotherapy in BED (mixed). Medications have short-term efficacy in BED (adults).

The Transition From Maternity Blues to Full-Blown Perinatal Depression: Results From a Longitudinal Study.

Background: The aims of the present study are to: (1) assess the frequency of maternity blues (MB); (2) identify the clinical and social characteristics more frequently associated with the onset of depressive symptoms after delivery; and (3) verify the hypothesis that the presence of maternity blues is a risk factor for the onset of a full-blown depressive episode in the 12 months after delivery. Methods: This is a longitudinal observational study. All pregnant women who gave birth at the inpatient unit of Gynecology and Obstetrics of the University of Campania "Luigi Vanvitelli" from December 2019 to February 2021 have been invited to participate in the study. Upon acceptance, women were asked to complete the Italian version of the Edinburgh Postnatal Depression Scale along with an ad-hoc questionnaire on the women's sociodemographic, gynecological and peripartum characteristics as well as their psychiatric history. Women have been reassessed after one, 3, 6 and 12 months. Results: A total of 359 women were recruited within 3 days from delivery, with a mean EPDS total score of 5.51 (±4.20). Eighty-three women (23.1%) reported the presence of maternity blues. Mean EPDS total scores were 12.8 (±0.2) in the MB group vs. 4.26 (±0.2) in the group without MB (p <0.0001). MB predictors were the presence of an anxiety disorder with an onset 6 months prior to pregnancy, of preeclampsia, of increased fetal health rate, of conflicts with relatives other than partner and having a partner with an anxiety disorder. At multivariate analyses the presence of MB increased 7-time the risk to have a higher EPDS score at follow-up assessments (OR: 7.79; CI: 6.88-8.70, p <0.000). This risk is almost four times higher 1 months after the delivery (OR: 4.66; CI: 2.54-6.75, p < 0.000), almost three times higher after 3 months (OR: 2.98; CI: 0.50-5.46, p < 0.01) and almost six times higher after 12 months (OR: 5.88; CI: 3.20-8.54, p < 0.000). Conclusions: Although MB was a self-limiting condition in the majority of cases, depressive symptoms arose quite often immediately after the childbirth. Professionals should be trained to monitor symptoms of MB and its transition toward a depressive episode.

COVID-19 Pandemic and Eating Disorders: What Can We Learn About Psychopathology and Treatment? A Systematic Review.

PURPOSE OF REVIEW: This systematic review aims to collect evidence regarding the impact of the SarsCov-2 pandemic on people affected by eating disorders (EDs) targeting the following variables: psychopathology changes, mechanisms of vulnerability or resilience, and perception of treatment modifications during the pandemic. RECENT FINDINGS: Since the beginning of the pandemic, a mental health deterioration has been detected in the general population and especially in people affected by pre-existing psychiatric conditions. Furthermore, mental healthcare has moved toward online treatment. ED people showed a trend toward worsening of ED-specific psychopathology and impairment in general psychopathology. The most common vulnerability mechanisms were social isolation and feelings of uncertainty, while heightened self-care and reduced social pressure were resilience factors. The online treatment, although raising many concerns related to its quality, was considered the best alternative to the face-to-face approach. These findings may support the idea that stressful events contribute to the exacerbation of ED psychopathology and highlight the relevance of internalizing symptoms in EDs. The identification of putative risk and resilience variables as well as of subjective factors affecting online treatment perception may inform healthcare professionals and may promote more personalized approaches.

Emotional traumatic experiences significantly contribute to identify a maltreated ecophenotype sub-group in eating disorders: Experimental evidence.

OBJECTIVE: Eating disorders (EDs) are associated with a high prevalence of childhood maltreatment (CM). We aimed to experimentally assess if people with EDs and history of CM show altered biological, emotional and behavioural responses to the Trier Social Stress Test (TSST). METHODS: According to Childhood Trauma Questionnaire cut-off scores, 29 participants (14 with anorexia nervosa [AN] and 15 with bulimia nervosa [BN]) were classified as maltreated (Mal) ED participants while 19 participants (11 with AN and eight with BN) without CM were identified as no maltreated (noMal) ED participants. Cortisol, anxiety and hunger responses to TSST and post-stress body dissatisfaction were measured. RESULTS: Mal ED people showed heightened emotional reactivity, lower levels of hunger and more severe post-stress body dissatisfaction in comparison with noMal ones. Higher cortisol production was observed in people with AN, regardless of CM history, and in those with BN and emotional CM. Emotional trauma was the main CM type contributing to the experimental differences observed in Mal ED people. CONCLUSIONS: This is the first study providing experimental and multi-level support to the maltreated ecophenoptype hypothesis in people with EDs. These findings may promote new insights into the biological bases of EDs and provide novel therapeutic implications.

Multiple levels assessment of the RDoC "system for social process" in Eating Disorders: Biological, emotional and cognitive responses to the Trier Social Stress Test.

BACKGROUND: Social dysfunction is a putative risk and maintaining factor for Eating Disorders (EDs). We assessed biological, emotional, and cognitive responses to a psychosocial stressor, in order to provide a multilevel investigation of the RDoC social process system in EDs. METHODS: Patients were recruited among those seeking treatment for an ED. Cortisol response to Trier Social Stress Test (TSST) was measured in 105 subjects: 35 women with anorexia nervosa (AN), 32 with bulimia nervosa (BN) and 38 healthy women. Anxiety, hunger, and desire to eat throughout TSST were rated in a subgroup of them (23 AN, 21 BN, and 25 control women). Two-way ANOVAs with repeated measures were run to assess differences among groups. RESULTS: The TSST-induced cortisol secretion of AN women was significantly higher than in BN and healthy women; this significance disappeared after controlling for body mass index. Compared to healthy women, both AN and BN women showed reduced cortisol reactivity that disappeared after controlling for trait anxiety and ineffectiveness. Both ED groups displayed increased anxiety response to TSST, while only AN group reported greater decreases in hunger and desire to eat. No significant correlations were found between cortisol and anxiety, hunger, or desire to eat in response to TSST. CONCLUSIONS: People with EDs are characterized by blunted cortisol reactivity and greater anxiety, hunger, and desire to eat responses to a psychosocial stressor without any significant association between these measures. This study provides the first empirical and multilevel support to a deranged functioning of the RDoC "system for social process" in EDs.

Affective Temperaments and Clinical Course of Bipolar Disorder: An Exploratory Study of Differences among Patients with and without a History of Violent Suicide Attempts.

Background and Objectives: Suicide is the leading cause of death in patients with Bipolar Disorder (BD). In particular, the high mortality rate is due to violent suicide attempts. Several risk factors associated with suicide attempts in patients with BD have been identified. Affective temperaments are associated with suicidal risk, but their predictive role is still understudied. The aim of this study is to assess the relationship between affective temperaments and personal history of violent suicide attempts. Materials and Methods: 74 patients with Bipolar Disorder type I (BD-I) or II (BD-II) were included. All patients filled in the short version of Munster Temperament Evaluation of the Memphis, Pisa, Paris and San Diego (short TEMPS-M) and the Temperament and Character Inventory, revised version (TCI-R). The sample was divided into two groups on the basis of a positive history for suicidal attempts and the suicidal group was further divided into two subgroups according to violent suicide attempts. Results: Violent suicide attempts were positively associated with the cyclothymic temperament and inversely to the hyperthymic one. BD-I patients and patients with a clinical history of rapid cycling were significantly more represented in the group of patients with a history of violent suicide attempts. Conclusions: Our study highlights that several clinical and temperamental characteristics are associated with violent suicide attempts, suggesting the importance of affective temperaments in the clinical management of patients with BPI.
