RESUMO
Objectives: Approximately one-third of bariatric surgery patients experience weight regain or suboptimal weight loss within five years post-surgery. Pathological eating styles and psychopathological traits (e.g., emotion dysregulation) are recognized as potential hindrances to sustain weight loss efforts and are implicated in obesity development. A comprehensive understanding of these variables and their interplays is still lacking, despite their potential significance in developing more effective clinical interventions for bariatric patients. We investigate the prevalence of and interactions between pathological eating styles and psychopathological traits in this population. Materials and methods: 110 bariatric surgery candidates were characterized using the Binge Eating Scale (BES), Hamilton Depression/Anxiety Scales (HAM-D/A), Barratt Impulsiveness Scale (BIS-11), Experiences in Close Relationships (ECR), Difficulties in Emotion Regulation Scale (DERS). We analyzed these variables with multiple logistic regression analyses and network analysis. Results: Patients with pathological eating styles showed more pronounced anxiety/depressive symptoms and emotion dysregulation. Network analysis revealed strong connections between BES and DERS, with DERS also displaying robust connections with HAM-A/D and ECR scales. DERS and attention impulsivity (BIS-11-A) emerged as the strongest nodes in the network. Discussion: Our findings demonstrate the mediating role of emotion dysregulation between pathological eating styles and psychopathological traits, supporting existing literature on the association between psychopathological traits, insecure attachment styles, and pathological eating behaviors. This research emphasizes the significance of emotion regulation in the complex network of variables contributing to obesity, and its potential impact on bariatric surgery outcomes. Interventions focusing on emotion regulation may thus lead to improved clinical outcomes for bariatric patients.
RESUMO
Important sex-related differences have been observed in the onset, prevalence, and clinical phenotype of depression, based on several epidemiological studies. Social, behavioural, and educational factors have a great role in underlying this bias; however, also several biological factors are extensively involved. Indeed, sexually dimorphic biological systems might represent the underlying ground for these disparities, including cerebral structures and neural correlates, reproductive hormones, stress response pathways, the immune system and inflammatory reaction, metabolism, and fat distribution. Furthermore, in this perspective, it is also important to consider and focus the attention on specific ages and life stages of individuals: indeed, women experience during their life specific periods of reproductive transitional phases, which are not found in men, that represent windows of particular psychological vulnerability. In addition to these, other biologically related risk factors, including the occurrence of sleep disturbances and the exposure to childhood trauma, which are found to differentially affect men and women, are also putative underlying mechanisms of the clinical bias of depression. Overall, by taking into account major differences which characterize men and women it might be possible to improve the diagnostic process, as well as treat more efficiently depressed individuals, based on a more personalized medicine and research.

BACKGROUND: Patients at ultra-high risk for psychosis (UHR) are a highly heterogeneous group in terms of clinical and functional outcomes. Several non-psychotic mental disorders co-occur together with the UHR state. Little is known about the impact of non-psychotic comorbid mental disorders on clinical and functional outcomes of UHR patients. METHODS: The sample included 154 UHR help-seeking patients (identified with the CAARMS, comprehensive assessment of the at-risk mental state), evaluated at baseline on the Ham-D, Ham-A (Hamilton depression/anxiety rating scale), and PANSS (positive and negative syndrome scale). 74 patients completed the 6-year follow-up assessment (mean=6.19, SD=1.87). Comorbid disorders at follow-up were assessed with the SCID I and II. Global functioning was rated on the global assessment of functioning (GAF) scale. RESULTS: In the present sample, 6-year risk of psychosis transition was 28.4%. Among non-transitioned UHR patients, 28.3% reported attenuated psychotic symptoms (APS) and 45.3% remained functionally impaired at follow-up (GAF<60). 56.8% patients were affected by at least one comorbid disorder at follow-up. Among UHR patients who presented with some comorbid disorder at baseline, 61.5% had persistent or recurrent course. Incident comorbid disorders emerged in 45.4% of baseline UHR patients. The persistence or recurrence of non-psychotic comorbid mental disorders was associated with poorer global functional outcomes at follow-up. LIMITATIONS: A substantial proportion of the initial sample was not available for follow-up interviews and some groups in the analyses had small sample size. Predictors of longitudinal outcomes were not explored. CONCLUSIONS: Among UHR patients, persistence or recurrence of non-psychotic comorbid mental disorders, mostly affective disorders, is associated with 6-year poor functional outcomes.

In spite of the increasing number of studies on insight in psychiatry and also in neurology and psychology, its nature is still elusive. It encompasses at least three fundamental characteristics: the awareness of suffering from an illness, an understanding of the cause and source of this suffering, and an acknowledgment of the need for treatment. As such, insight is fundamental for patients' management, prognosis, and treatment. Not surprisingly, the majority of available data, which have been gathered on schizophrenia, show a relationship between low insight and poorer outcomes. For mood disorders, however, insight is associated with less positive results. For other psychiatric disorders, insight has rarely been investigated. In neurology, the impaired ability to recognize the presence of sensory, perceptual, motor, affective, or cognitive functioning-referred to as anosognosia-has been related to damage of specific brain regions. This article provides a comprehensive review of insight in different psychiatric and neurological disorders, with a special focus on brain areas and neurotransmitters that serve as the substrate for this complex phenomenon.

Major depression is associated with a 4-fold increased risk for premature death, largely accounted by cardiovascular disease (CVD). The relationship between depression and CVD is thought to be mediated by the so-called metabolic syndrome (MeS). Epidemiological studies have consistently demonstrated a co-occurrence of depression with MeS components, ie, visceral obesity, dyslipidemia, insulin resistance, and hypertension. Although the exact mechanisms linking MeS to depression are unclear, different hypotheses have been put forward. On the one hand, MeS could be the hallmark of the unhealthy lifestyle habits of depressed patients. On the other, MeS and depression might share common alterations of the stress system, including the hypothalamus-pituitary-adrenal (HPA) axis, the autonomic nervous system, the immune system, and platelet and endothelial function. Both the conditions induce a low grade chronic inflammatory state that, in turn, leads to increased oxidative and nitrosative (O&NS) damage of neurons, pancreatic cells, and endothelium. Recently, neurobiological research revealed that peripheral hormones, such as leptin and ghrelin, which are classically involved in homeostatic energy balance, may play a role in mood regulation. Metabolic risk should be routinely assessed in depressed patients and taken into account in therapeutic decisions. Alternative targets should be considered for innovative antidepressant agents, including cytokines and their receptors, intracellular inflammatory mediators, glucocorticoids receptors, O&NS pathways, and peripheral mediators.

One of the most intriguing frontiers of current neuroscientific research is represented by the investigation of the possible neural substrates of morality. The assumption is that in humans an innate moral sense would exist. If this is true, with no doubt it should be regulated by specific brain mechanisms selected over the course of evolution, as they would promote our species' survival. In the last decade, an increasing number of studies have been carried out to explore the neural bases of human morality.The aim of this paper is to present a comprehensive review of the data regarding the neurobiological origin of the moral sense, through a Medline search of English-language articles from 1980 to February 2012.The available findings would suggest that there might be a main integrative centre for the innate morality, in particular the ventromedial prefrontal cortex, with its multiple connections with the limbic lobe, thalamus and brainstem. The subjective moral sense would be the result of an integration of multiple automatic responses, mainly associated with social emotions and interpretation of others' behaviours and intentions.Since converging observations outline how lesions of the proposed neural networks may underlie some personality changes and criminal behaviours, the implications of the studies in this field encompass many areas of the scientific domain.
RESUMO
A large amount of the data gathered in the last 50 years support the hypothesis that alterations of the serotonin (5-HT) neurotransmission play a crucial role in the pathophysiology of not only major depression (MD), but also of different neuropsychiatric disorders. Research in this field has been substantially promoted by the evidence that the reuptake protein (SERT), present in presynaptic neurons, is a key element in terminating the activity of the neurotransmitter in the synaptic cleft. For this reason, it was specifically targeted for the development of second-generation antidepressants, in particular of selective 5-HT reuptake inhibitors (SSRIs), with the aim of increasing the intrasynaptic 5-HT concentrations. Moreover, since a lot of studies showed that circulating platelets and, more recently, lymphocytes possess functional SERT proteins, they have been widely used as peripheral mirrors of the same structures located in the central nervous system. The presence of functional SERT in blood cells suggests strict relationships between the nervous and the immune system that need to be better clarified in MD, as well as the possibility of reciprocal modulation of the two systems by different drugs. This paper aims to review briefly the literature on the 5-HT hypothesis of depression with a major focus on the possible role of SERT in this disorder, while highlighting how recent data are more oriented on dimensional rather than nosological involvement of this structure in different conditions spanning from normality to pathology.

BACKGROUND: Most of our social interactions involve perception of emotional information from the faces of other people. Furthermore, such emotional processes are thought to be aberrant in a range of clinical disorders, including psychosis and depression. However, the exact neurofunctional maps underlying emotional facial processing are not well defined. METHODS: Two independent researchers conducted separate comprehensive PubMed (1990 to May 2008) searches to find all functional magnetic resonance imaging (fMRI) studies using a variant of the emotional faces paradigm in healthy participants. The search terms were: "fMRI AND happy faces," "fMRI AND sad faces," "fMRI AND fearful faces," "fMRI AND angry faces," "fMRI AND disgusted faces" and "fMRI AND neutral faces." We extracted spatial coordinates and inserted them in an electronic database. We performed activation likelihood estimation analysis for voxel-based meta-analyses. RESULTS: Of the originally identified studies, 105 met our inclusion criteria. The overall database consisted of 1785 brain coordinates that yielded an overall sample of 1600 healthy participants. Quantitative voxel-based meta-analysis of brain activation provided neurofunctional maps for 1) main effect of human faces; 2) main effect of emotional valence; and 3) modulatory effect of age, sex, explicit versus implicit processing and magnetic field strength. Processing of emotional faces was associated with increased activation in a number of visual, limbic, temporoparietal and prefrontal areas; the putamen; and the cerebellum. Happy, fearful and sad faces specifically activated the amygdala, whereas angry or disgusted faces had no effect on this brain region. Furthermore, amygdala sensitivity was greater for fearful than for happy or sad faces. Insular activation was selectively reported during processing of disgusted and angry faces. However, insular sensitivity was greater for disgusted than for angry faces. Conversely, neural response in the visual cortex and cerebellum was observable across all emotional conditions. LIMITATIONS: Although the activation likelihood estimation approach is currently one of the most powerful and reliable meta-analytical methods in neuroimaging research, it is insensitive to effect sizes. CONCLUSION: Our study has detailed neurofunctional maps to use as normative references in future fMRI studies of emotional facial processing in psychiatric populations. We found selective differences between neural networks underlying the basic emotions in limbic and insular brain regions.

INTRODUCTION: Impairment in sexual function is frequent and underestimated in patients with mental disorders, particularly in those with mood disorders. Few studies have examined the relationship between sexual dysfunctions and the clinical characteristics of mood disorders. AIM: The aim of the present study was to explore the frequency of sexual dysfunctions in patients with bipolar I disorder (BD) and unipolar depression (UD) with respect to control subjects, as well as their relationship with suicidality. MAIN OUTCOME MEASURES: Assessments included: the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (SCID-I/P), the 24-item Brief Psychiatric Rating Scale and the Mood Spectrum Self-Report, a questionnaire exploring lifetime mood spectrum symptomatology including symptoms of sexual functioning and suicidality. METHODS: A consecutive sample of 142 patients (60 BD and 82 UD) and a comparison group of 101 control subjects were recruited in a multicenter study involving 11 academic departments of psychiatry. RESULTS: Lifetime impairment in the sexual response cycle, including desire, excitement, and ability to achieve orgasm, was significantly more common in patients with mood disorders compared with control subjects. Increase in sexual activity and promiscuity were significantly more common in patients with BD vs. the other two groups. Lifetime dysfunctions in all three phases of the sexual response cycle explored were significantly associated with lifetime suicide attempts in patients with BD and with thoughts of death in patients with UD. In BD patients, the lifetime presence of periods with frequent changes of sexual partners was significantly associated with thoughts of death. CONCLUSIONS: Our findings suggest the importance of assessing sexual dysfunctions in patients with either BD or UD, as they may be clinically helpful in identifying phenotypes of mood disorders characterized by high suicidality.

OBJECTIVE: To assess the efficacy of dexketoprofen (DEX) in reducing pain at different stages of the hysteroscopic procedure in comparison with local anaesthesia in menopausal women. METHODS: Menopausal patients affected by uterine bleeding submitted to diagnostic hysteroscopy, were randomised to receive either 25 mg DEX tablet (n = 148) or intracervical injection of 5 ml mepivacaine 2% (n = 150). Pain suffered during the procedure itself and 30, 60, 120 min after, was scored on the 11 point Visual Analogic Scale, recorded and analysed. RESULTS: No statistical difference were noted during the procedure itself in both groups of treatment. Patients treated with DEX has significantly less postoperative pain. CONCLUSIONS: DEX is not superior to mepivacaine in reducing the discomfort of the procedure but does significantly reduce postoperative pain.
