Orthorexia nervosa (ON) is an emerging condition featuring restrictive eating behaviors on the basis of subjective beliefs about food healthiness. Many authors have stressed the similarities between ON and anorexia nervosa (AN) in both cognitive and behavioral patterns. Despite that, while the link between AN and female autism presentations is well known in the literature, no study has yet investigated the relationship between ON and autism spectrum. This work aims to investigate the relationship between ON and autistic traits in a university population.
Methods
An e-mail invitation was sent to all the students and University workers of University of Pisa. Subjects were asked to fulfill the ORTO-15 and the Adult Autism Subthreshold spectrum (AdAS spectrum) questionnaires.
Results
A total of 2426 subjects joined the survey: 623 subjects (26.3%) reported a score associated with significant orthorexic symptoms according to ORTO-15 (ON group), while 1789 subjects (73.7%) did not report ON symptomatology and were considered as healthy controls (HC). The ON group scored significantly higher on almost all AdAS spectrum domains. Moreover, being female and scoring higher on AdAS spectrum were statistically predictive factors for the presence of ON symptomatology. Among AdAS spectrum domains, higher scores on AdAS spectrum inflexibility and adherence to routine and restricted interests and rumination domains, as well as lower scores on verbal communication domain, were statistically predictive of orthorexic symptoms.
Conclusions
Our findings highlight an overlap between ON and autism spectrum psychopathology. Further studies are needed to clarify the relationship between restrictive eating disorders and female autism phenotypes.
Skin picking disorder and trichotillomania, also characterized as body-focused repetitive behaviors (BFRBs), often lead to functional impairment. Some people with BFRBs, however, report little if any psychosocial dysfunction. There has been limited research as to which clinical aspects of BFRBs are associated with varying degrees of functional impairment.
Methods
Adults (n = 98), ages 18 to 65 with a current diagnosis of trichotillomania (n = 37), skin picking disorder (n = 32), trichotillomania plus skin picking disorder (n = 10), and controls (n = 19) were enrolled. Partial least squares regression (PLS) was used to identify variables associated with impairment on the Sheehan Disability Scale.
Results
PLS identified an optimal model accounting for 45.8% of variation in disability. Disability was significantly related to (in order of descending coefficient size): severity of picking, perceived stress, comorbid disorders (specifically, anxiety disorders / obsessive–compulsive disorder), trait impulsivity, family history of alcohol use disorder, atypical pulling/picking sites, and older age.
Conclusions
At present mental disorders are viewed as unitary entities; however, the extent of impairment varies markedly across patients with BFRBs. These data suggest that whereas symptom nature/severity is important in determining impairment, so too are other variables commonly unmeasured in clinical practice. Outcomes for patients may thus be maximized by rigorously addressing comorbid disorders; as well as integrating components designed to enhance top-down control and stress management. Interestingly, focused picking and emotional pulling were linked to worse disability, hinting at some differences between the two types of BFRBs, in terms of determinants of impairment.
To evaluate the effectiveness of long-acting injectable antipsychotics (LAI-a) in reducing the 90-day and annual readmission rates in schizophrenia inpatients.
Methods
We conducted a cross-sectional study and included 180 adult patients with psychotic disorders discharged from 2018 to 2019 at a state psychiatric hospital. Descriptive statistics were used to measure the differences between the readmit and nonreadmit cohorts. Logistic regression model was used to measure the odds ratio (OR) for 90-day and annual readmission and was controlled for potential readmission risk factors.
Results
A lower proportion of patients receiving LAI-a were readmitted within 90-day (28.6%) and 1-year (32.4%) periods. Patients receiving LAI-a had lower odds of association for 90-day (OR 0.36, 95% confidence intervals [CI] 0.139-0.921) and annual (OR 0.35, 95% CI 0.131-0.954) readmissions compared to those discharged on oral antipsychotics. A higher proportion of inpatients who received fluphenazine LAI had 90-day (25%) and annual (18.2%) readmissions compared to other LAI-a.
Conclusion
Utilization of LAI-a in patients with psychotic disorders can decrease both 90-day and annual psychiatric readmissions by 64% to 65%. Physicians should prefer LAI-a to reduce the readmission rate and improve the quality of life, and decrease the healthcare-related financial burden.
The aim of this study is to examine the effects of quetiapine as an adjuvant treatment for obsessive–compulsive (OC) symptoms in patients with bipolar disorder (BD) type I.
Methods
In this 8-week double-blind placebo-controlled randomized clinical trial, 47 patients with BD in euthymic phase that had OC symptoms were randomly allocated to receive either quetiapine or placebo plus their routine medications (lithium + clonazepam). Yale–Brown Obsessive–Compulsive Scale (YBOCS) was used to assess the outcomes. Adverse effects were also recorded.
Results
Of 47 BD patients with OC symptoms that were randomly allocated in two groups of quetiapine (n = 24) and placebo group (n = 23), 40 patients (20 in quetiapine group and 20 in placebo group) completed the trial. Throughout the trial, the mean score of YBOCS in the quetiapine group dropped from 24.37 ± 1.51 to 15.26 ± 1.16 (P < .001) and in the placebo group decreased from 24.21 ± 1.33 to 23.94 ± 1.66 (P = 1.97). At the end of the study, 12 (60%) patients in the quetiapine group and 1 (5%) patient in the placebo group had more than 34% decline in YBOCS score (P < .001). No serious adverse effects were reported in two groups.
Conclusions
Our double-blind placebo-controlled clinical trial showed that quetiapine may be an effective adjuvant agent for reducing OC symptoms in BD patients.
Altered peripheral immune/inflammatory system and brain volumetric changes have been implicated in the pathophysiology of bipolar disorder (BD). This study aimed to evaluate how peripheral levels of cytokines are related to volumetric brain changes in euthymic patients with BD.
Methods
Euthymic patients with BD (n = 21) and healthy controls (n = 22) were enrolled in this exploratory study. Blood samples were collected on the same day of clinical assessment and neuroimaging. Cytokines were measured through cytometric bead array method. Neuroimaging data were acquired using a sagittal three-dimensional magnetic resonance imaging T1-weighted fast field echo sequence and was processed using FreeSurfer.
Results
Compared to controls, BD patients had significantly lower volumes in the cingulate, medial-orbitofrontal (MOF) and parahippocampal regions. We found a negative correlation between right MOF volume and interferon-gamma levels (β = −0.431, P = .049) and a positive correlation between interleukin-10 levels and left posterior cingulate volume (β = 0.457, P = .048).
Conclusion
Our results support the involvement of inflammatory pathways in structural brain changes in BD.
Obsessive–compulsive disorder (OCD) is a severe psychiatric disorder characterized by its heterogeneous nature and by different dimensions of obsessive–compulsive (OC) symptoms. Serotonin reuptake inhibitors (SRIs) are used to treat OCD, but up to 40% to 60% of patients do not show a significant improvement with these medications. In this study, we aimed to test the impact of brain-derived neurotrophic factor (BDNF) Val66Met polymorphism on the efficacy of antidepressants in OCD overall, and in relation to the different OC dimensions.
Methods
In a 6-month prospective treatment study, 69 Caucasian OCD patients were treated with escitalopram for 24 weeks or with escitalopram for 12 weeks followed by paroxetine for an additional 12-week period. Patients were genotyped and assessed for treatment response. The main clinical outcomes were improvement of the Yale-Brown Obsessive–Compulsive Scale score and in different OC symptom dimension scores.
Results
The Val/Val group comprised 43 (62%) patients, the Val/Met and Met/Met group comprised 26 (38%) patients. Forty-two patients were classified as responders at 12 weeks and 38 at 24 weeks; no significant association was found between BDNF Val66Met and SRIs response at 12 and 24 weeks. In analyses of the different OC symptom dimensions, the Met allele was associated with a slightly reduced score in the aggressive/checking dimension at 6 months (P = .048).
Conclusions
Our findings do not support the usefulness of BDNF Val66Met genotyping to predict overall response to treatment with SRIs in OCD; they did however suggest a better outcome at 6 months for the aggressive/checking symptom dimension for patients carrying the Met allele.
Mental pain has been proposed as a global person-centered outcome measure. The aim of this cross-sectional study was to test an essential requisite of such a measure, namely that mental pain incorporates independent contributions from a range of discrete but disparate outcome measures.
Methods
Two hundred migraine patients were assessed concerning migraine disability, psychosomatic syndromes, mental pain, depression, anxiety, and psychosocial dimensions. General linear models were tested to verify which measures would individually make unique contributions to overall mental pain.
Results
The final model, accounting for 44% of variance, identified that higher mental pain was associated with more severe depressive symptoms, higher migraine disability, lower well-being, and poorer quality of life.
Conclusion
In this sample, mental pain was shown to behave as expected of a global outcome measure, since multiple measures of symptomatology and quality of life showed modest but significant bivariate correlations with mental pain and some of these measures individually made unique contributions to overall mental pain.
