RESUMO

BACKGROUND: In recent years, numerous studies have highlighted the overlap between autism spectrum disorder (ASD) and catatonia, both from a clinical and pathophysiological perspective. This study aimed to investigate the relationship between the autism spectrum (autistic traits and ASD signs, symptoms, and behavioral manifestation) and Catatonia Spectrum (CS). METHODS: A total sample of 376 subjects was distributed in four diagnostic groups. Subjects were assessed with the Structured Clinical Interview for DSM-5, Research Version, the Adult Autism Subthreshold Spectrum (AdAS Spectrum), and CS. In the statistical analyses, the total sample was also divided into three groups according to the degree of autism severity, based on the AdAS Spectrum total score. RESULTS: A statistically significant positive correlation was found between AdAS Spectrum and CS total score within the total sample, the gender subgroups, and the diagnostic categories. The AdAS Spectrum domains found to be significantly and strongly correlated with the total CS score were hyper-hypo reactivity to sensory input, verbal communication, nonverbal communication, restricted interests and rumination, and inflexibility and adherence to routine. The three groups of different autistic severity were found to be distributed across all diagnostic groups and the CS score increased significantly from the group without autistic traits to the group with ASD. CONCLUSIONS: Our study reports a strong correlation between autism spectrum and CS.

RESUMO

PURPOSE: This cross-sectional study aimed at comparing the quality of life (Qol), the prevalence of psychiatric diagnosis and pharmacological treatment in 104 candidates to bariatric surgery according to the degree of obesity (class 2 vs. class ≥ 3 obesity). METHODS: All surgical candidates underwent a detailed psychiatric interview based on DSM-5 criteria, including sociodemographic, clinical, psychological and psychiatric data. Participants completed the Binge Eating Scale (BES) and the 12-Item Short Form Health Survey (SF-12). RESULTS: Overall, bariatric candidates reported a significant impairment in the physical (PCS 38.8 [95% CI 36.2-41.5]) and mental (MCS 42.2 [95% CI 40.4-43.9]) components of Qol compared to population norms (p < 0.001 for both). Subjects with class 2 obesity scored significantly lower in the MCS compared to those with class 3 (38.7 (8.1) vs. 43.6 (8.4), p = 0.008). No other statistically significant differences were found between the two groups in terms of sociodemographic and clinical variables. CONCLUSION: These data support the usefulness of Qol assessment in bariatric candidates as a sensible screening parameter, especially in patients with lower BMI, in whom MCS could identify the need for early psychosocial intervention. LEVEL OF EVIDENCE: Level III, case-control analytic study.

RESUMO

Background: The literature shows that parents of preterm infants are at risk of psychological distress and that this may impact on the quality of the parent-child relationship and on the child's development.Aim: This longitudinal study was conducted to examine in preterm infants relationships between maternal psychological variables, parental protective factors, perinatal infant variables, and neurodevelopmental outcome. Furthermore, we explored the impact of these variables on the quality of the mother-infant relationship (dyadic synchrony).Subjects and methods: A total of 29 preterm infants (GA < 34 weeks) and their mothers were evaluated twice: at t0, during the infant's hospitalization in the neonatal intensive care unit (NICU), and at 12 months of infant corrected age (t2).Results: With the exception of decreases in anxiety and perceived social support and an increase in the rate of severe depression at follow-up, there were no significant changes between t0 and t1 assessments. The infant's perinatal risk status was the variable that impacted most on maternal psychopathology. Furthermore, our data revealed that baseline maternal stress related to the appearance of the child and to the mother's perception of her parenting role represent a risk factor in relation to developmental outcome at 12 months of corrected age. Finally, no correlations emerged between dyadic synchrony and infant perinatal data, maternal psychological variables (at t0 and at t1), or child developmental outcome at t1.Conclusions: Our results underline the need to identify negative maternal affective states early in the mother-child relationship and to provide mothers with adequate support in the NICU, to enhance their parental role.

RESUMO

BACKGROUND: While growing literature is stressing the link between Autistic Traits (AT) and trauma-/stress-related disorders, in both conditions significant differences have been separately reported. OBJECTIVE: This study aims to evaluate the relationship between AT and trauma-/stress-related symptoms with respect to sex. METHODS: 178 university students were assessed with the Structured Clinical Interview for DSM-5, the Trauma and Loss Spectrum (TALS) and the Adult Autism Subthreshold Spectrum (AdAS). In order to evaluate sex differences in trauma-/stress-related symptoms among subjects with higher or lower AT, the sample was split in two groups with an equal number of subjects on the basis of the median score reported on AdAS Spectrum ("AdAS high scorers" and "AdAS low scorers"). RESULTS: Females reported significantly higher TALS total score, Loss events and Grief reaction domain scores than males in the whole sample, while AdAS high scorers reported significantly higher TALS total and domain scores than AdAS low scorers. A significant interaction between high/low AdAS score and sex emerged for TALS domains, with females scoring significantly higher than males only among AdAS low scorers, specifically on Loss events, Grief reaction, Re-experiencing and Personal characteristics/Risk factors domains. Finally, among AdAS high scorers a significantly higher rate of subjects fulfilled symptomatological criteria for PTSD than among AdAS low scorers, without sex differences. CONCLUSION: Our results confirm a significant relationship between AT and trauma-/stress-related symptoms, which seems to prevail on sex differences among high-risk subjects.

RESUMO

BACKGROUND: Autism spectrum is a psychopathological dimension which encompasses a wide range of clinical presentations: from subthreshold forms and autistic traits (AT), that can be found in the general population, to full-blown autism spectrum disorder (ASD). Many studies reported high rates of comorbidity between both ASD and AT and mood disorders, as well as a high prevalence of suicidal ideation among patients with ASD/AT. The aim of this study was to investigate the presence of mood symptoms and suicidal ideation and behaviors in patients with full-blown ASD and in subjects with AT, as well in a healthy control (HC) group, with a specific focus on which of the autistic features may be predictive of suicidal ideation and behaviors. METHODS: We recruited 262 adult subjects: 34 with ASD without intellectual impairment or language disability (ASD group), 68 fulfilling only one symptom criterion for ASD according to DSM-5 but who do not meet criteria for a full-blown diagnosis of ASD (AT group), and 160 HC. All subjects were assessed with the Structured Clinical Interview for DSM-5 (SCID-5); in addition, they were asked to fill two questionnaires: The Mood Spectrum, Self-report (MOODS-SR) and the Adult Autism Subthreshold Spectrum (AdAS Spectrum). RESULTS: ASD subjects reported significantly higher AdAS Spectrum and MOODS-SR total scores, as well as higher MOODS-SR depressive component total scores, when compared with AT and HC subjects. AT subjects scored significantly higher than the HC group. No significant differences were reported between ASD and AT subjects for the suicidality score according to MOODS-SR, despite both groups scored significantly higher than the HC group. The strongest predictor of suicidality score were MOODS-SR depressive component score and AdAS Spectrum Restricted interests and rumination domain score. CONCLUSIONS: Our results highlight a correlation between autism and mood spectrum, as well as between suicidality and both ASD and AT. Subthreshold forms of ASD should be accurately investigated due to their relationship with suicidal thoughts and behaviors.

RESUMO

BACKGROUND: In the context of kidney transplantation (KT), multidisciplinary interventions, including assessment and management of psychosocial aspects, are important to improve transplant's outcome. The aim of this study was to describe a multidisciplinary team approach to KT, with a specific focus on early detection and treatment of psychological distress and psychopathologic conditions in the early phase postsurgery. METHODS: The multidisciplinary team in kidney transplantation was implemented in January 2016. In this team approach, all transplant recipients are invited to 3 scheduled appointments for a multidisciplinary evaluation at 1, 3, and 6 months posttransplant, including a psychiatric interview, with the aim to assess the patient's adjustment after transplantation and provide support when necessary. RESULTS: This pilot study involved all 41 KT recipients consecutively referred for the first multidisciplinary appointment after transplantation. Five subjects (12% of the study sample) presented with a current psychiatric diagnosis. Psychopharmacologic treatment was confirmed or introduced for all these patients. Further psychological support was suggested to 4 other patients (10%). CONCLUSION: KT significantly improves patients' quality of life. However, the percentage of subjects receiving psychopharmacologic treatment and referred for further psychological and psychiatric support (22%) suggests the need for careful monitoring of psychosocial aspects over the long term.

RESUMO

INTRODUCTION: From the prognostic perspective, the quality of the mother-child relationship during the first months of life has been variously associated with different factors such as the child's psychomotor/cognitive development and emotional-behavioral disorders. METHODS: The main aim of this study was to describe, at term age and 3 months of corrected age, the features and the prevalent patterns of the mother-child relationship in a group of 20 mother-preterm infant dyads and to compare them with those of a group of 20 mother-term infant dyads. RESULTS: A relatively high rate of inadequate dyadic synchrony was found in our sample of preterms at 40 weeks of gestational age (half of the sample analyzed). The quality of the dyadic relationship and the prevalent patterns of the mother-child relationship were found to differ between the two groups we studied; moreover, the subjects at risk of relational problems remained substantially the same during the first 3 months of life. DISCUSSION: These data underline that in preterm children, the first weeks of life, coinciding with their hospitalization, represent a crucial time for establishing a valid dyadic relationship and for considering and planning any preventive interventions; after all, the earlier the risk of relational problems becomes a real possibility, the more likely it is to negatively impact on a child's overall development.

RESUMO

OBJECTIVE: The aim of the present systematic review and meta-analysis was to evaluate the impact of physical exercise on cognitive symptoms in depressed adult patients. METHODS: Systematic literature search was performed in Web of Science™ and CINAHL from inception to August 2016. Two reviewers independently selected randomized trials evaluating the effect of exercise on cognitive functions in patients with a validated diagnosis of depression. Outcome measures included global cognition and different cognitive domains (speed of processing, attention/vigilance, working memory, verbal and visual memory, and reasoning). RESULTS: Eight trials met inclusion criteria (637 patients). A fixed-effects model showed absence of beneficial effect on global cognition (Hedges' g = 0.07, 95% CI -0.08 to 0.24, I2  = 0%) as well as on specific cognitive domains. Sensitivity analyses did not show an impact of exercise in studies with shorter intervention duration compared to longer trials (between group heterogeneity Q = 3.564, df = 1, P = 0.059), single session per week compared to multiple sessions (Q = 2.691, df = 1, P = 0.101) and low exercise intensity compared with moderate/high intensity (Q = 2.952, df = 1, P = 0.086). CONCLUSION: Our meta-analysis did not observe a substantial benefit of physical exercise on cognitive symptoms in depression.

RESUMO

AIM: Increasing literature has shown the usefulness of a dimensional approach to autism. The present study aimed to determine the psychometric properties of the Adult Autism Subthreshold Spectrum (AdAS Spectrum), a new questionnaire specifically tailored to assess subthreshold forms of autism spectrum disorder (ASD) in adulthood. METHODS: 102 adults endorsing at least one DSM-5 symptom criterion for ASD (ASDc), 143 adults diagnosed with a feeding and eating disorder (FED), and 160 subjects with no mental disorders (CTL), were recruited from 7 Italian University Departments of Psychiatry and administered the following: SCID-5, Autism-Spectrum Quotient (AQ), Ritvo Autism and Asperger Diagnostic Scale 14-item version (RAADS-14), and AdAS Spectrum. RESULTS: The AdAS Spectrum demonstrated excellent internal consistency for the total score (Kuder-Richardson's coefficient=.964) as well as for five out of seven domains (all coefficients>.80) and sound test-retest reliability (ICC=.976). The total and domain AdAS Spectrum scores showed a moderate to strong (>.50) positive correlation with one another and with the AQ and RAADS-14 total scores. ASDc subjects reported significantly higher AdAS Spectrum total scores than both FED (p<.001) and CTL (p<.001), and significantly higher scores on the Childhood/adolescence, Verbal communication, Empathy, Inflexibility and adherence to routine, and Restricted interests and rumination domains (all p<.001) than FED, while on all domains compared to CTL. CTL displayed significantly lower total and domain scores than FED (all p<.001). A significant effect of gender emerged for the Hyper- and hyporeactivity to sensory input domain, with women showing higher scores than men (p=.003). A Diagnosis* Gender interaction was also found for the Verbal communication (p=.019) and Empathy (p=.023) domains. When splitting the ASDc in subjects with one symptom criterion (ASD1) and those with a ASD, and the FED in subjects with no ASD symptom criteria (FED0) and those with one ASD symptom criterion (FED1), a gradient of severity in AdAS Spectrum scores from CTL subjects to ASD patients, across FED0, ASD1, FED1 was shown. CONCLUSIONS: The AdAS Spectrum showed excellent internal consistency and test-retest reliability and strong convergent validity with alternative dimensional measures of ASD. The questionnaire performed differently among the three diagnostic groups and enlightened some significant effects of gender in the expression of autistic traits.

RESUMO

BACKGROUND AND AIMS: The EpiCom study and inception cohort was initiated in 2010 in 31 centers from 14 Western and 8 Eastern European countries, covering a 10.1million person background population. Our aim was to investigate whether there is a difference between Eastern and Western Europe in health care and education of patients with inflammatory bowel disease (IBD). METHODS: A quality of care (QoC) questionnaire was developed in the EpiCom group consisting of 16 questions covering 5 items: time interval between the onset of symptoms and diagnosis, information, education, empathy and access to health care providers. RESULTS: Of 1,515 patients, 947 (217 east/730 west) answered the QoC questionnaire. Only 23% of all patients had knowledge about IBD before diagnosis. In Eastern Europe, significantly more patients searched out information about IBD themselves (77% vs. 68%, p<0.05), the main source was the Internet (92% vs. 88% p=0.23). In Western Europe, significantly more patients were educated by nurses (19% vs. 1%, p<0.05), while in Eastern Europe, gastroenterologists were easier to contact (80% vs. 68%, p<0.05). CONCLUSION: Health care differed significantly between Eastern and Western Europe in all items, but satisfaction rates were high in both geographic regions. Because of the low awareness and the rising incidence of IBD, general information should be the focus of patient organizations and medical societies. In Western Europe IBD nurses play a very important role in reducing the burden of patient management.

RESUMO

OBJECTIVES: To address at a meta-analytical level the neuroanatomical markers of genetic liability to psychosis and a of first episode of psychosis. METHODS: Fifteen voxel-based morphometry (VBM) studies of antipsychotic-naive subjects at genetic high-risk (HR) for psychosis or with a first-episode psychosis (FEP) were included in a Signed Differential Mapping (SDM) meta-analysis. Publication bias was assessed with funnel plots and Egger's intercept. Heterogeneity was assessed with Q statistics and I (2) index. RESULTS: The database comprised 458 HR and 206 antipsychotic-naïve FEP subjects, matched with controls. Gray matter (GM) reductions as compared to controls, were observed in the left parahippocampal gyrus and in the bilateral anterior cingulate gyrus in the HR group, and in the right superior temporal gyrus, in the left insula and in the left cerebellum in the FEP group. Further GM decreases were observed in the FEP group as compared to the HR group in the left anterior cingulate, in the right precuneus, in the left cerebellum and in the right superior temporal gyrus. Limitations. The cross-sectional nature of the included studies prevented the comparison of high risk subjects who later did or did not develop a psychotic episode. Other caveats are based on the methodological heterogeneity across individual imaging studies. CONCLUSIONS: GM reductions in the anterior cingulate are markers of genetic liability to psychosis while reductions in the superior temporal gyrus and cerebellum can be interpreted as markers of a first onset of the illness.

RESUMO

BACKGROUND: This study examined the prevalence of students' reported experiences of bullying and victimization in primary and secondary schools and their association with levels of perceived stress and cannabis use. METHODS: We consecutively enrolled 407 students attending three secondary schools in Pavia (Italy). Bullying and victimization were measured using the retrospective bullying questionnaire (RQB). The 10-item perceived stress scale (PSS-10) was used to assess the degree to which situations in life were perceived as stressful. Data on demographic characteristics and cannabis use in the previous 6 months were also collected. RESULTS: There were 328 victims (80.6%) and 221 bullies (52.1%). The results of the stepwise regression analysis with bullying as the dependent variable were significant with either male sex (R2 = 0.030, p = 0.024) or PSS-10 scores (R2 0.056, p = 0.036) in the model. With victimization as the dependent variable, only the PSS-10 scores were retained in the model as an independent predictor variable (R2 = 0.048, p<0.001). CONCLUSIONS: The results from this study indicate that the level of perceived stress has an independent association with both bullying and victimization. Further studies are needed to clarify the psychobiological links between stress, cannabis use and bullying behaviours.

RESUMO

OBJECTIVE: Recent observations showed that long chain omega 3 polyunsaturated fatty acids (n-3 LCPUFA) could represent a potential treatment for elderly depression. To determine if a n-3 LCPUFA containing supplement improves depressive symptoms, changes phospholipids acids profile and ameliorates Health related quality of life (HRQoL) in depressed elderly patients. DESIGN: Two-months, randomized, double-blind, placebo-controlled trial. SETTING: Nursing home in Pavia, Italy. SUBJECTS: Forty-six depressed females, aged 66-95 years. INTERVENTION: 22 depressed females were included in the intervention group (n-3 group, that received 2.5 g/day of n-3 LCPUFA, with 1.67 grams of EPA and 0.83 grams of DHA), and 24 patients in the placebo group. The primary endpoint was the improvement of depressive symptoms as evaluated by Geriatric Depression Scale (GDS). Secondary endpoints were the evaluation of modifications of erythrocyte membrane phospholipids fatty acid profile and of of HRQoL, by using the Short-Form 36-Item Health Survey (SF-36). All parameters were assessed before and after the treatment period of 8 weeks. RESULTS: The mean GDS at 2 months was significantly lowered only for the n-3 group. SF-36 physical and mental components were significantly increased in the intervention group. Compliance was good, as confirmed by erythrocyte membrane phospholipid FA concentrations, with significant increase of EPA and DHA in the intervention group. CONCLUSION: The supplementation of n-3 LCPUFA in elderly female patients reduces the occurrence of depressive symptoms, improves phospholipids fatty acids profile and health-related quality of life.

RESUMO

We demonstrate experimentally dynamic interface binding in a system consisting of two coupled ferromagnetic layers. While domain walls in each layer have different velocity-field responses, for two broad ranges of the driving field H, walls in the two layers are bound and move at a common velocity. The bound states have their own velocity-field response and arise when the isolated wall velocities in each layer are close, a condition which always occurs as H→0. Several features of the bound states are reproduced using a one-dimensional model, illustrating their general nature.

RESUMO

Mental processing is the product of the huge number of synaptic interactions that occur in the brain. It is easier to understand how brain functions can deteriorate than how they might be boosted. Lying at the border between the humanities, cognitive science and neurophysiology, some mental diseases offer new angles on this problematic issue. Despite their social deficits, autistic subjects can display unexpected and extraordinary skills in numerous fields, including music, the arts, calculation and memory. The advanced skills found in a subgroup of people with autism may be explained by their special mental functioning, in particular by their weak central coherence, one of the pivotal characteristics of the disorder. As a result of the increasing interest in autistic talent, there has recently emerged a tendency to screen any eccentric artist or scientist for traits of the autistic spectrum. Following this trend, we analyze the eccentricity of the popular pianist Glenn Gould and briefly discuss the major functional hypotheses on autistic hyperfunctioning, advancing proposals for functional testing. In particular, the potential involvement of rhythm-entrained systems and cerebro-cerebellar loops opens up new perspectives for the investigation of autistic disorders and brain hyperfunctioning.

RESUMO

Recognizing emotion from facial expressions draws on diverse psychological processes implemented in a large array of neural structures. Two major theories of cerebral lateralization of emotional perception have been proposed: (i) the Right-Hemisphere Hypothesis (RHH) and (ii) the Valence-Specific Hypothesis (VSH). To test these lateralization models we conducted a large voxel-based meta-analysis of current functional magnetic resonance imaging (fMRI) studies employing emotional faces paradigms in healthy volunteers. Two independent researchers conducted separate comprehensive PUBMED (1990-May 2008) searches to find all functional magnetic resonance imaging studies using a variant of the emotional faces paradigm in healthy subjects. Out of the 551 originally identified studies, 105 studies met inclusion criteria. The overall database consisted of 1785 brain coordinates which yield an overall sample of 1600 healthy subjects. We found no support for the hypothesis of overall right-lateralization of emotional processing. Conversely, across all emotional conditions the parahippocampal gyrus and amygdala, fusiform gyrus, lingual gyrus, precuneus, inferior and middle occipital gyrus, posterior cingulated, middle temporal gyrus, inferior frontal and superior frontal gyri were activated bilaterally (p=0.001). There was a valence-specific lateralization of brain response during negative emotions processing in the left amygdala (p=0.001). Significant interactions between the approach and avoidance dimensions and prefrontal response were observed (p=0.001).

RESUMO

BACKGROUND AND AIMS: Communication to patients of information about their disease has become increasingly important in modern medicine, and particularly with chronic nonfatal disorders like inflammatory bowel disease (IBD), but the subject is not adequately researched or understood. METHODS: We studied the media and preferences for communication of information in a multi-national community-based inception cohort of European and Israeli patients with IBD and 10 years follow-up, using structured questionnaires categorizing demographics, disease status, current and preferred sources of information, use of electronic media, role of patients' associations, and satisfaction level. RESULTS: The 917 patients completing the questionnaire were derived from northern (60%) and southern (40%) countries. The mean age was 48.3 years (62% under 50 years); 51% were males; 67% had ulcerative colitis, 33% Crohn's disease. Sixty-six percent of patients designated the specialist as their primary source of information, 77% indicated satisfaction with their current information, and 65% reported not receiving information about medical treatment in the past year. Patient concerns were about new research into their illness (64%), medical treatments (58%), risks and complications (51%) and genetics (42%). Preferred sources of information were paper bulletin (76%), electronic media (30%) and international organization (79%). Diagnosis (ulcerative colitis or Crohn's disease), gender, education level and country impacted significantly on patients' choices. CONCLUSIONS: In providing health care information to patients with IBD their individual attitudes and preferences must be considered. There should be greater roles for IBD patients' associations and international IBD-research organizations, and an increasing use of electronic media.

RESUMO

During the postoperative course of lung transplantation, patients may experience depressive symptoms that negatively influence their ability to cope with the new organ, their adherence to rehabilitation and pharmacologic therapy, and their overall quality of life (QoL). To date, no review has explored the causes of depression following transplantation or the efficacy and safety of therapeutic interventions in this patient group. We conducted a comprehensive 1966-2006 MEDLINE, EMBASE, and PsycINFO search for studies of the causes and treatments of depression in lung transplant recipients. We identified 25 studies of variable methodologic quality. Depression rates are high among candidates for lung transplantation. In the short term, after surgery depressive symptoms remain low with an improvement in QoL, whereas in the long term (>3 years), the decline of functional status is associated with a dramatic increase in such symptomatology. Personality disorders, coping strategies, stressful life events, physical complications, corticosteroid medications, age, gender, and psychosocial support all play a central role in causing depressive states in lung transplant recipients. Serotonin reuptake inhibitors (SSRIs) and new-generation antidepressants (mirtazapine) represent the best therapeutic choices for this group of patients. The risk of serious drug-drug interactions should be carefully monitored by experienced clinicians. Complementary therapies and psychoeducational intervention also help recipients to strengthen their coping strategies, offering further advantages after transplantation. Additional well-conducted randomized controlled trials are needed to clarify the epidemiologic course of depression following lung transplantation and to tailor effective pharmacologic or psychological interventions accordingly.
