Associations of potential plasma biomarkers with suicide attempt history, current suicidal ideation and subsequent suicidal events in patients with depression: A discovery study.

A growing body of evidences suggests that suicidal ideation (SI) and suicidal behaviors have biological bases. However, no biological marker is currently available to evaluate the suicide risk in individuals with SI or suicide attempt (SA). Moreover, the current risk assessment techniques poorly predict future suicidal events. The aim of this study was to examine the association of 39 new and already described peripheral cells and proteins (implicated in the immune system, oxidative stress and plasticity) with lifetime SA, past month SA, current SI, and future suicidal events (visit to the Emergency Department for SI or SA) in 266 treatment-seeking individuals with mood disorders. Equal parts of patients with and without past history of SA were recruited. All individuals at inclusion gave blood, were evaluated for SA recency, current SI, and were followed for two years afterwards. The 39 peripheral blood cellular and protein markers were entered separately for each outcome in Elastic Net models with 10-fold cross-validation, followed by single-analyte covariate-adjusted regression analyses for pre-selected analytes. Past month SA was associated with increased plasma levels of thrombospondin-2 and C-reactive protein, whereas current SI was associated with lower plasma serotonin levels. These associations were robust to adjustments for key covariates and corrections for multiple testing. The Cox proportional hazards regression showed that higher levels of thrombospondin-1 and of platelet-derived growth factor-AB predicted a future suicidal event. These two associations remained after adjustment for sex, age, and SA history, and outperformed the predictive value of past SA. Thrombospondins and platelet-derived growth factors have never been investigated in the context of suicide. Altogether, our results highlight the involvement in the suicidal process of platelet biological response and plasticity modifiers and also of inflammatory factors. They also suggest that SI and SA may have different biological correlates and that biomarkers associated with past SA or current SI do not automatically also predict future events.

A specific association between laxative misuse and suicidal behaviours in patients with anorexia nervosa and bulimia nervosa.

OBJECTIVE: Eating disorders (ED) are associated with an in increased risk of suicidal behaviours. Laxative abuse might alter the gut-brain axis signaling, that might be implicated in the pathophysiology of suicide. This study aims to determine the association between laxative misuse and suicide attempt (SA) and suicidal ideation (SI) in patients with ED. METHODS: 277 patients with ED were recruited from an Eating Disorder Unit of Lapeyronie Academic Hospital, Montpellier, France. Sociodemographic and clinical data were collected. Chi-square and t test were used, with Bonferroni corrections where required. Multiple regression models assessed the relationships between laxative misuse, SA, and SI. RESULTS: 62 (22.4%) patients reported lifetime laxative misuse. They were more likely to have a history of SA than non-misusers [43.83 vs 19.9%, p < 0.001, odds ratio (OR) 3.68]. In the multivariate model, adjusted for other confounders, lifetime laxative misuse remained associated with SA (adjusted OR 3.79, p = 0.041). In past 28 days, patients with SA history reported misusing laxatives for more days than patients without SA history (6 vs 1.5 days, p = 0.01, adjusted for vomiting and ED severity). Laxative use days during past 28 days was associated with current SI, adjusted for vomiting in the same period (p = 0.017). CONCLUSIONS: Current and lifetime laxative misuse were associated with SA history and current SI in patients with ED, at least in part independently of other suicide-related factors. LEVEL OF EVIDENCE: Level III cohort, cross-sectional study.

The implications of previous history of anorexia nervosa in patients with current bulimia nervosa: Alterations in daily functioning, decision-making, and bone status.

OBJECTIVE: It is not yet clear what role previous history of anorexia nervosa (AN) plays in the clinical course of bulimia nervosa (BN). We aimed to investigate, using a comprehensive assessment, involving clinical characteristics, daily functioning, cognitive functions, and nutritional and physical markers in BN patients with a history of AN, and compare them with BN patients without a history of AN. METHODS: Eighty-five patients with a current episode of BN (35 with a lifetime history of AN) were analysed. Diagnoses were established according to the DSM-5 criteria. Patients completed neuropsychological tests and filled out validated psychiatric questionnaires. Sociodemographic data and nutritional and somatic illness markers were collected and investigated. RESULTS: BN patients with a history of previous lifetime AN had worse decision-making ability, worse general and specific functioning, decreased bone density, more antecedent of lifetime suicide attempts, more dietary restraint, and more frequent use of laxatives. The multivariate model shows that the history of AN is closely associated with worse decision-making ability, worse general function, and higher likelihood of lifetime suicide attempts. DISCUSSION: Prior history of AN is an important clinical question that should receive proper attention when treating BN patients, as this subgroup of patients may have specific care needs.

Effects of the two types of anorexia nervosa (binge eating/purging and restrictive) on bone metabolism in female patients.

OBJECTIVE: This study compared the profiles of the two types of anorexia nervosa (AN; restrictive: AN-R, and binge eating/purging: AN-BP) in terms of body composition, gynaecological status, disease history and the potential effects on bone metabolism. DESIGN: Two hundred and eighty-six women with AN (21.8 ± 6.5 years; 204 AN-R and 82 AN-BP) and 130 age-matched controls (CON; 22.6 ± 6.8 years) were enrolled. Areal bone mineral density (aBMD) was determined using DXA and resting energy expenditure (REE) was indirectly assessed using calorimetry. Markers of bone formation (osteocalcin [OC], procollagen type I N-terminal propeptide [PINP] and resorption (type I-C telopeptide breakdown products [CTX]) and leptin were concomitantly evaluated. RESULTS: Anorexia nervosa patients presented an alteration in aBMD and bone turnover. When compared according to type, AN-BP were older than AN-R and showed less severe undernutrition, lower CTx levels, longer duration of AN, and higher REE levels and aBMD at radius and lumbar spine. After adjustment for age, weight and hormonal contraceptive use, the aBMD and CTx differences disappeared. In both AN groups, aBMD was positively correlated with anthropometric parameters and negatively correlated with durations of AN and amenorrhoea, the bone formation markers (OC and PINP) and the leptin/fat mass ratio. REE was positively correlated with aBMD in AN-R patients only. CONCLUSIONS: This study shows the profiles of AN patients according to AN type. However, the impact of the profile characteristics on bone status, although significant, was minor and disappeared after multiple adjustments. The positive correlation between REE and aBMD reinforces the concept that energy disposal and bone metabolism are strongly interdependent.

Improving decision-making and cognitive impulse control in bulimia nervosa by rTMS: An ancillary randomized controlled study.

OBJECTIVE: Impaired decision-making and inhibitory control may be involved in the pathophysiology of psychiatric disorders like bulimia nervosa (BN). Their improvement after neuromodulation may underpin clinical improvement. We assessed the effects of rTMS on these cognitive functions in a sample of women with BN. METHODS: Thirty-nine participants (22 in a sham group and 17 in an rTMS group) were assessed before and after 10 high frequency rTMS sessions over the left dorsolateral prefrontal cortex (DLPFC). RESULTS: The between-group analyses revealed no differences in the final neuropsychological performances. The within-group analyses showed that inhibitory control improved in both the go/no-go task (p = .03) and the BIS cognitive impulsivity subscale (p = .01) in the rTMS group only. Switches toward good choices on the Iowa gambling task significantly improved in the rTMS group only (p = .002), and understanding of the task contingencies increased between the two assessments, also in the rTMS group only (p = .03). DISCUSSION: This preliminary evidence suggests that modulation of left DLPFC might improve two putative cognitive biomarkers of BN.

A Lack of Clinical Effect of High-frequency rTMS to Dorsolateral Prefrontal Cortex on Bulimic Symptoms: A Randomised, Double-blind Trial.

Studies suggest that stimulation of the left dorsolateral prefrontal cortex (DLPFC) reduces food craving in bulimic patients, but evidence supporting repetitive transcranial magnetic stimulation (rTMS) as a therapeutic tool is lacking. We investigated the safety and therapeutic efficacy of an adjunct high-frequency rTMS programme targeting the left DLPFC. Forty-seven women with bulimia nervosa were randomised to a real or sham stimulation group. The real group underwent 10 rTMS sessions, each consisting of 20 trains of 5 seconds with 55-second intervals between trains, at a frequency of 10 Hz. The main outcome was the number of binge episodes in the 15 days following the end of stimulation. Overall, no significant improvement in bingeing and purging symptoms was noted after the programme. rTMS was well tolerated. This suggests that 10 sessions of high-frequency rTMS to the left DLPFC provide no greater benefit than placebo. Future studies should consider methodological issues as well as alternative targets.

Effectiveness of the first French psychoeducational program on unipolar depression: study protocol for a randomized controlled trial.

BACKGROUND: Major Depressive Disorder (MDD) is highly prevalent and was associated with greater morbidity, mortality (including suicide), and healthcare costs. By 2030, MDD will become the leading cause of disability in high-income countries. Notably, among patients with a previous experience of a major depressive episode, it was indeed estimated that up to 85 % of those patients will suffer from relapse. Two main factors were associated with a significantly higher risk of relapse: poor medication adherence and low self-efficacy in disease management. Interestingly, these issues could become the targets of psychoeducational programs for chronic diseases. Indded psychoeducational program for depression are recommended in international guidelines, but have not yet been proposed in France. METHODS/DESIGN: We propose to evaluate the first French psychoeducational program for depression "ENVIE" in a multicenter randomized controlled trial. The group intervention will include 9 weekly sessions. Its aim is to educate patients on the latest knowledge on depression and effective treatments through didactic and interactive sessions. Patients will experiment the latest innovating psychological skills (from acceptance and commitment therapy) to cope with depressive symptoms and maintain motivation in behavioral activation. In total, 332 unipolar non-chronic (<2 years) outpatients with moderate to severe depression, without psychotic features, will be randomly allocated to the add-on ENVIE program (N = 166) or to a waiting list (N = 166). The follow-up will last 15 months and include 5 assessment visits. The primary endpoint will be the remission rate of the index episode at 15 months post-inclusion, defined by a Montgomery and Asberg Depression Rating Scale (MADRS) score ≤ 12 over an 8-week period, and without relapse during follow-up. We will also assess the response rate and relapse at 15 months post-inclusion, hospitalization rate and adherence to treatment during the follow-up period, quality of life and global functioning upon inclusion and at 9 and 15 months post inclusion. DISCUSSION: If the proposed trial shows the effectiveness of the intervention, but also an increased remission rate in depressed outpatients at 15-months post-inclusion, in addition to improved treatment adherence in patients, it will further promotes arguments in favor of a wide dissemination of psychoeducational programs for depression. TRIAL REGISTRATION: This trial is registered under number 2015-A00249-40 (PURE clinical trial: NCT02501226 ) (June 30th, 2015).

Baseline circulating biomarkers, their changes, and subsequent suicidal ideation and depression severity at 6 months: A prospective analysis in patients with mood disorders.

BACKGROUND: Identifying circulating biomarkers associated with prospective suicidal ideation (SI) and depression could help better understand the dynamics of these phenomena and identify people in need of intense care. In this study, we investigated the associations between baseline peripheral biomarkers implicated in neuroplasticity, vascular homeostasis and inflammation, and prospective SI and depression severity during 6 months of follow-up in patients with mood disorders. METHODS: 149 patients underwent a psychiatric evaluation and gave blood to measure 32 plasma soluble proteins. At follow-up, SI incidence over six months was measured with the Columbia Suicide Severity Rating Scale, and depressive symptoms were assessed with the Inventory for Depressive Symptomatology. Ninety-six patients provided repeated blood samples. Statistical analyses included Spearman partial correlation and Elastic Net regression, followed by the covariate-adjusted regression models. RESULTS: 51.4 % (N = 71) of patients reported SI during follow-up. After adjustment for covariates, higher baseline levels of interferon-γ were associated with SI occurrence during follow-up. Higher baseline interferon-γ and lower orexin-A were associated with increased depression severity, and atypical and anxious, but not melancholic, symptoms. There was also a tendency for associations of elevated baseline levels of interferon-γ, interleukin-1ß, and lower plasma serotonin levels with SI at the six-month follow-up time point. Meanwhile, reduction in transforming growth factor- ß1 (TGF-ß1) plasma concentration correlated with atypical symptoms reduction. CONCLUSION: We identified interferon-γ and orexin-A as potential predictive biomarkers of SI and depression, whereas TGF-ß1 was identified as a possible target of atypical symptoms.

Association between childhood maltreatment and obsessive-compulsive disorder comorbid with eating disorders: a cross-sectional study.

BACKGROUND: Obsessive-compulsive disorder (OCD) and eating disorders (ED) share common features, including the presence of obsessions and compulsions, and they often co-occur. Additionally, there is a significant comorbidity between ED and childhood traumatic experiences (CTE), as well as between CTE and OCD. Various biological and environmental factors have been proposed to explain the connection between ED, OCD, and CTE. This study explores the link between CTE and the comorbidity of ED and OCD, with the hypothesis that specific types of CTE may increase the risk of developing OCD in individuals with ED. METHODS: Participants (N = 562) were enrolled at an eating disorder unit in Montpellier, France, between March 2013 and January 2020. The Childhood Trauma Questionnaire (CTQ), Eating Disorder Examination Questionnaire (EDE-Q), and Mini International Neuropsychiatric Interview (MINI) were used to evaluate childhood maltreatment, assess clinical characteristics associated with ED, and categorize participants into two groups: patients with and without OCD. RESULTS: Bivariate analysis revealed that patients with comorbid ED and OCD had higher EDE-Q scores (p < 0.001), more anxiety disorders (p < 0.001), depressive disorders (p = 0.02), post-traumatic stress disorder (PTSD) (p < 0.001), and a higher incidence of sexual abuse (p < 0.001) and physical neglect (p = 0.04) compared to those without OCD. Multivariate analysis showed that the association between CTE and OCD was influenced by the presence of an anxiety disorder (p = 0.01) and a higher EDE-Q total score (p = 0.03), with a significant association with a history of sexual abuse (p = 0.04). CONCLUSIONS: This demonstrates that CTE increases the risk of comorbid OCD in ED patients, correlating with more clinically severe ED and a higher likelihood of anxiety disorders.

This study looked at the link between childhood trauma and the occurrence of both obsessive-compulsive disorder (OCD) and eating disorders (ED). We studied 562 participants who were being treated for eating disorders in Montpellier, France, over a seven-year period. We used various questionnaires to evaluate their childhood experiences, eating disorder symptoms, and the presence of OCD. We found that people with comorbid OCD and ED had more severe eating disorder symptoms and higher rates of anxiety, depression, and PTSD compared to those with just an eating disorder. These individuals were also more likely to have experienced sexual abuse and physical neglect during childhood. Our analysis showed that the connection between childhood trauma and OCD in patients with eating disorders was influenced by the presence of anxiety disorders and more severe eating disorder symptoms. Specifically, a history of sexual abuse was a significant factor. In summary, childhood trauma, especially sexual abuse, increases the risk of having both OCD and an eating disorder. This highlights the importance of screening for OCD and addressing past traumas in patients with eating disorders to provide better, more personalized care.

Weight suppression at lowest weight as an indicator of eating disorder clinical severity: A retrospective cohort study.

OBJECTIVES: Weight suppression (WS) defines the difference between the highest weight in adulthood and the current weight. WS at lowest weight is the difference between the highest and the lowest ever weight. Weight rebound is the difference between the past lowest weight and current weight. The distinction in the capacities of WS, weight rebound, and WS at the lowest weight remains unclear regarding their efficacy in forecasting clinical endpoints. This study assessed the relationship between WS, WS at lowest weight and/or weight rebound and eating disorder (ED) clinical severity. METHODS: In this retrospective cohort study, adult participants were selected at the Outpatient Unit for multidisciplinary assessment of ED, Montpellier, France, between February 2012 and October 2014 and May 2017 and January 2020. ED clinical severity was evaluated using the Eating Disorder Examination Questionnaire (EDE-Q). RESULTS: The sample included 303 patients: 204 with anorexia nervosa (AN) and 99 with bulimia nervosa (BN). The EDE-Q total score was positively correlated with WS at lowest weight in patients with AN (Spearman's rho = 0.181, p = 0.015) and with BN (Spearman's rho = 0.377; p < 0.001). It was also positively correlated with weight rebound (Spearman's rho = 0.319; p = 0.003) in patients with BN. In the multivariate analysis, EDE-Q total score was associated with WS at lowest weight only in patients with BN (ß = 0.265; p = 0.03). CONCLUSION: WS at lowest weight seems to be a good measure of ED clinical severity. More research is needed for better understanding WS at lowest weight in assessment and treatment of patients with ED.

Clinical Correlates of Measured and Predicted Resting Energy Expenditure in Patients with Anorexia Nervosa: A Retrospective Cohort Study.

Resting energy expenditure (REE; i.e., the calorie amount required for 24 h during a non-active period) is an important parameter in nutritional rehabilitation of patients with anorexia nervosa (AN). This study determined whether age, body mass index, AN duration/subtype/specific symptoms/clinical severity, cognitive function alterations, and psychiatric comorbidities influenced REE or the difference between the calculated and estimated REE. Patients with AN who were followed at a daycare treatment facility between May 2017 and January 2020 (n = 138) underwent a complete assessment that included the MINI, Eating Disorder Examination Questionnaire, d2 test of attention, body fat composition by bioelectrical impedance analysis (BIA) and REE measurement by indirect calorimetry (REEIC). AN subtype (N = 66 for restrictive subtype and N = 69 for non-restrictive subtype; p = 0.005), free-fat mass (<0.001), and fat mass (<0.001) were associated with REEIC. Age (p < 0.001), height (p = 0.003), and AN duration (N = 46 for <3 years and N = 82 for ≥3 years; p = 0.012) were associated with the difference between estimated REE (using the Schebendach equation) and measured REEIC. Therefore, the Schebendach equation was adjusted differently in the two patients' subgroups (AN duration ≤ or >3 years). Overall, REE was higher in patients with restrictive than non-restrictive AN. In the absence of BIA measures, REE-estimating equations should take into account AN duration.

Combined effects of nitric oxide synthase 3 genetic variant and childhood emotional abuse on earlier onset of suicidal behaviours.

Marked heterogeneity in suicide attempters has been observed, with earlier onset being linked to stronger heritability, more childhood maltreatment. Nitric oxide signalling system might be implicated in this relationship through its role in the stress response/adaptation. This study examined how NOS genetic variants and childhood maltreatment were associated with age at first suicide attempt (SA). Adult patients with SA history (N = 414) filled in the Childhood Trauma Questionnaire, and six functionally relevant NOS2 and NOS3 polymorphisms were genotyped. Analyses included χ2, Mann-Whitney U tests, Kendall's regression, multivariate linear and Cox survival regressions, and a moderation analysis. The NOS3 promotor 27-bp variable number tandem repeat (VNTR) bb homozygous state and childhood emotional abuse were independently associated with earlier age at first SA, which was robust after controlling for confounders [regression coefficient - 3.975, 95% CI -6.980 - (-0.970), p = 0.010, and - 1.088, 95% CI -2.172 - (-0.004), p = 0.049]. No interaction was observed. In the Cox proportional hazards model for age at first SA, the hazard ratio for patients with childhood emotional abuse and NOS3 27-bp VNTR bb was 0.533 (95% CI 0.394-0.720, p < 0.001) compared to patients without. Intermediate scores were observed with either only the risk genotype or only childhood emotional abuse. A graded relationship was also observed for repeated SA, family history of SA, and severe SA history. These results are preliminary due to a low statistical power and call for replication and further characterization of the role of nitric oxide system in the susceptibility to early-onset SB.

Selenium deficiency is associated with disease severity, disrupted reward processing, and increased suicide risk in patients with Anorexia Nervosa.

BACKGROUND & AIMS: Patients with Anorexia Nervosa (AN) present many nutritional deficiencies (macro- and often also micro-nutrients), possibly explained by their inadequate food intake. Previous studies reported that selenium (Se) deficiency is common in the general population. As Se can be easily added as a supplement, the goal of this study was to evaluate the clinical impact of Se deficiency in patients with AN. METHODS: This cross-sectional study concerned 153 patients with AN (92.9% women) followed at the Eating Disorder Unit of Lapeyronie Academic Hospital, Montpellier, France. Patients underwent an extensive neuropsychological assessment, and completed validated questionnaires. Blood samples were collected for Se quantification. Results were compared with the t-test, Mann-Whitney U, and Chi square tests, and univariate linear and multivariate logistic regression models. RESULTS: Se plasma levels were below the cut-off of 80 µg/L in 53.6% (N = 82) of patients. AN onset was earlier in patients with Se deficiency, (p = .005), whereas disease duration was comparable between groups (p = .77). General eating disorder symptomatology in the past 28 days (Eating Disorder Examination Questionnaire) was more severe in patients with Se deficiency (p = .010). The suicide risk (MINI International Neuropsychiatric Evaluation) tended to be higher (p = .037), and suicide attempt history was more frequent (28.39% vs 9.85%, p = .004) in patients with low Se levels. Se plasma concentration was negatively correlated with the performance in the temporal delayed discounting task (p = .006). CONCLUSIONS: Our findings suggest that in patients with AN, Se plasma concentration might be implicated in disease severity and suicide risk. The finding that Se deficiency in patients with AN was associated only with reward-related processes, but not with other psychological functions suggests the selective involvement of dopamine-related pathways. Our results suggest that it might be useful to monitor the plasma micronutrient profile in patients with AN. Future studies should determine whether Se supplementation in AN might improve clinical outcomes.

Effects of Hormonal Contraception Use on Cognitive Functions in Patients With Bulimia Nervosa.

Background: Growing evidences indicate that sex hormones have an effect on cognitive functions, and that Bulimia Nervosa (BN) is associated with cognitive impairment. The aim of this study was to determine the effect of hormonal contraception (HC) use on four cognitive functions that are impaired in patients with BN. Methods: This retrospective exploratory study included 103 women with a diagnosis of BN based on the DSM-5 criteria. Their age ranged from 15 to 45 years, and 46.6% were taking HC (oral, transdermal, or intrauterine). Cognition was assessed with the d2 test (attention), Iowa gambling task (IGT; decision making), Brixton spatial anticipation test (set shifting), and Rey-Osterrieth complex figure test (central coherence). Data were analyzed with logistic regression models to estimate the adjusted odds ratios (OR) and 95% confidence intervals (CI) of HC effect on the neuropsychological test scores. Results: In the multivariate model, HC use was significantly associated with better scores for two d2 test indices: F-score [OR = 0.98, 95% CI = (0.95; 0.99)] and final total score ratio [OR = 0.87, 95% CI = (0.77; 0.99)]. HC was also associated with a better understanding of the IGT explicit rules. No difference between the two groups (HC and non-HC use) was detected for set shifting and central coherence. Conclusions: This exploratory study suggests that HC could have effects on the sustained attention and concentration in women with BN. More studies are needed to confirm these results.

Joint Hypermobility and Clinical Correlates in a Group of Patients With Eating Disorders.

Background: The ability to move joints beyond the normal range of motion is called Joint Hypermobility (JHM). JHM has been associated with a plethora of physical problems and is a frequent sign of hereditary disorders of connective tissue. Neuropsychiatric conditions such as eating disorders (ED) have also been related to JHM. However, little is known about the clinical profile of people with ED and JHM. The aim of this study was to explore JHM in patients with ED and to compare the clinical characteristics of hypermobile ED patients with non-hypermobile ED patients. Method: Fifty-three outpatients diagnosed with ED were assessed using the Beighton score for JHM, the Eating Disorders Inventory 2, the Eating Disorder Examination, and the Detail and Flexibility Questionnaire. Information relating to patients' psychiatric and somatic comorbidities/symptoms was also collected. Results: Using the traditional Beighton score's cutoff of ≥4, 41.5% of the sample presented with JHM. Our results indicate that compared with non-hypermobile ED patients, those with JHM are significantly younger, suffer at a greater extent from joint pain and easy bruising, have a shorter duration of the ED, and have lower scores for cognitive rigidity. In addition, for those with anorexia nervosa, the restricting subtype represents a significantly lower proportion of hypermobile ED patients compared to non-hypermobile ED patients. Multivariate analyses showed that cognitive rigidity, age, and duration of the ED could predict the JHM status in this sample. Conclusion: These results suggest that JHM is frequent in patients with ED and is accompanied by signs of tissue fragility. Patients with ED and JHM seem to present a specific profile characterized by less cognitive rigidity and restricting behavior in the case of anorexia nervosa. Further research is needed in order to confirm these results.

Sociocultural Attitudes Towards Appearance Questionnaire-4: Psychometric properties among a French clinical eating disorder sample and normative comparisons.

Although the Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4) has been shown to be a reliable and valid tool for assessing appearance pressures and appearance ideal internalization among French college students, to date its psychometric properties among French clinical populations have not been examined. The aim of this study was to evaluate the factor structure, reliability, and validity of the SATAQ-4 among a French female clinical eating disorder sample, and to compare the mean SATAQ-4 scores from this clinical sample to previously published means observed among French female college women. The current sample included 192 French women consecutively recruited from an outpatient eating disorders unit in France. Participants completed the SATAQ-4, as well as validated measures of body image and eating pathology. Confirmatory factor analysis revealed that the original 22-item five-factor solution provided less than adequate fit to the data. In contrast, the reduced 20-item five-factor solution identified among French college students provided a good fit to the data. The SATAQ-4 subscales generally exhibited moderate positive associations with convergent measures of body image and eating disturbance, consistent with expectations. Differences in SATAQ-4 subscale means across diagnostic groups were observed. In addition, the clinical group reported higher scores on the Internalization: Thin/Low Body Fat and Internalization: Muscular/Athletic subscales compared to a non-clinical French sample. Findings support the SATAQ-4 as a valuable tool for assessing sociocultural influences on body image and eating concerns among French women with eating disorders.

The quantitative ultrasound method for assessing low bone mass in women with anorexia nervosa.

This study investigated the potential role of quantitative ultrasound (QUS) to assess low bone mass in anorexia nervosa patients (AN). Bone parameters from QUS and DXA were positively correlated and significantly reduced in AN compared with controls, suggesting that QUS is a pertinent technique to assess low bone mass in these patients. PURPOSE: The aim of this study was to investigate the potential role of an alternative technique, quantitative ultrasound (QUS), to assess low bone mass in patients with anorexia nervosa (AN). METHODS: Two hundred seven young women (134 patients with AN and 73 healthy controls) with ages ranging from 14.4 to 38.4 years participated in this observational cross-sectional study. Bone mass was concomitantly evaluated by DXA to determine areal bone mineral density (aBMD; g/cm2) at hip, lumbar spine, and radius and by QUS to determine broadband ultrasound attenuation (BUA; dB/MHz) at the heel. RESULTS: BUA (66.5 ± 4.6 dB/MHz vs 61.0 ± 5.0 dB/MHz) and aBMD at the hip (0.916 ± 0.013 g/cm2 vs 0.806 ± 0.010 g/cm2), lumbar spine (0.966 ± 0.012 g/cm2 vs 0.886 ± 0.010 g/cm2), and radius (0.545 ± 0.005 g/cm2 vs 0.526 ± 0.04 g/cm2) were significantly decreased (p < 0.01) in patients with AN compared with controls. When patient and control data were pooled, BUA was significantly correlated with aBMD at the hip (r = 0.60, p < 0.001), lumbar spine (r = 0.48, p < 0.001), and radius (r = 0.40, p<0.001). In patients with AN, BUA and aBMD were mainly and positively correlated with weight, lean tissue mass, body mass index (BMI), and minimal BMI life and negatively with the duration of both disease and amenorrhea. Better concordance between the two techniques was obtained when absolute BUA and aBMD values were used according to the WHO T score classification. CONCLUSION: BUA measurement at the heel by QUS appears to be a pertinent nonionizing technique to assess low bone mass in patients with AN.

Brain Stimulation in Eating Disorders: State of the Art and Future Perspectives.

The management of eating disorders (EDs) is still difficult and few treatments are effective. Recently, several studies have described the important contribution of non-invasive brain stimulation (repetitive transcranial magnetic stimulation, transcranial direct current stimulation, and electroconvulsive therapy) and invasive brain stimulation (deep brain stimulation and vagal nerve stimulation) for ED management. This review summarizes the available evidence supporting the use of brain stimulation in ED. All published studies on brain stimulation in ED as well as ongoing trials registered at clinicaltrials.gov were examined. Articles on neuromodulation research and perspective articles were also included. This analysis indicates that brain stimulation in EDs is still in its infancy. Literature data consist mainly of case reports, cases series, open studies, and only a few randomized controlled trials. Consequently, the evidence supporting the use of brain stimulation in EDs remains weak. Finally, this review discusses future directions in this research domain (e.g., sites of modulation, how to enhance neuromodulation efficacy, personalized protocols).

I Cannot Read Your Eye Expression: Suicide Attempters Have Difficulties in Interpreting Complex Social Emotions.

Background: The ability to differentiate emotions in social contexts is important for dealing with challenging social situations. Suicide attempters show some difficulties in emotion recognition that may result in hypersensitivity to social stress. However, other studies on the recognition of social complex emotions found that suicide attempters have similar performances as depressed non-attempters. Objectives: To investigate differences in social emotion recognition in patients with current Major Depressive Episode (MDE) with and without history of suicide attempt. Methods: Two hundred and ten patients with MDE were recruited among whom 115 had lifetime history of suicide attempt (suicide attempters, SA) and 95 did not (affective controls, AC). Recognition of complex social emotions was assessed using the Reading the Mind in the Eyes Test (RMET). Emotions were separated in three valence categories: positive, negative, and neutral. Verbal intelligence quotient (IQ) and attention were measured with the National Adult Reading Task (NART) and the d2 test, respectively. Results: Mixed logistic regression models adjusted for sex, lifetime bipolar disorder, verbal IQ and attention showed that the RMET performance for neutral emotions was worse in the SA than AC group (OR = 0.87 [0.75, 0.99]). Furthermore, when violent/serious SA were compared to non-violent/non-serious SA and AC, the RMET neutral valence category showed a trend for group factor (p < 0.059) and RMET scores were lower in the violent/serious SA than AC group (OR = 0.79 [0.64, 0.96]). Conclusion: Recognition of neutral emotions is poor in SA and this may complicate their daily life. Interventions to improve the understanding of complex emotions may be helpful to prevent suicidal risk in patients with depression.
