Abstract
The present study aims to test the psychometric properties of the Portuguese version of the "How I Think" (HIT) questionnaire. The HIT questionnaire is a self-report measure of self-serving cognitive distortions. Our sample was comprised of 442 Portuguese-speaking adolescents and young adults (254 males and 188 females), aged between 12 and 20 years. Of the total 442 participants, 351 were recruited from a Portuguese school and 91 from four Portuguese detention centers for juvenile delinquents. Data analysis provided evidence supporting the original six-factor model solution, composed of a four-category typology of self-serving cognitive distortions (i.e., Selfcentered, Blaming Others, Minimizing/Mislabeling, and Assuming the Worst), an Anomalous responding, and one Positive filler factor. Further, results showed satisfactory internal consistency, convergent validity, and discriminant validity. In conclusion, this article provides Portuguese researchers and practitioners with a valid measure of self-serving cognitive distortions.

Abstract
Introduction Obsessive-compulsive disorder (OCD) is a chronic, prevalent, and highly impairing psychiatric illness. While its aetiology remains unknown, several infectious agents have been associated to obsessive-compulsive symptoms, including herpes simplex virus 1 (HSV-1) and Toxoplasma gondii. Objectives To evaluate the serostatus for HSV-1 and Toxoplasma gondii in sample of patients with OCD, as well as its clinical and brain imaging correlates. Methods
Twenty-six patients with OCD and 30 healthy controls recruited in Lisbon were assessed for sociodemographic and clinical characteristics using the Yale-Brown Obsessive-Compulsive Scale-II (YBOCS-II) and the Beck Depression Inventory-II (BDI-II). Seropositivity for HSV-1 and Toxoplasma gondii was assessed in serum using ELISA, and volumes of cortical and subcortical structures were assessed using T1-weighted magnetic resonance imaging. Results YBOCS-II and BDI-II scores were significantly higher in patients, while age, sex, smoking status, and seropositivity for HSV-1 and Toxoplasma gondii were similar between the two groups. Among OCD patients, those seropositive for HSV-1 had significantly lower volumes of total white-matter, total grey-matter, left and right putamen, while for HSV-1 seropositive healthy controls, only the last two were significantly smaller. In multiple regression analyses to control for age, associations between HSV-1 and brain volumes were conserved, while the effect of age was not significant. No significant differences were found in brain volumes of patients with OCD according to seropositivity for Toxoplasma gondii. Conclusions Our preliminary results suggest that in patients with OCD, seropositivity to HSV-1 is associated with smaller volumes of total white- and grey-matter in the brain. Disclosure No significant relationships.

Abstract
Introduction
Although difficult to define, the concept of evil is widely used and implicitly influences psychiatric judgements and diagnosis. Most definitions of evil rely on classical philosophical concepts, but it remains controversial if evil is a concept by itself or rather a dysfunction on the ability to experience goodness. Also, it is unclear if there is a neurobiological basis for evil or if it is entirely dependent on socio-cultural beliefs.
Objectives
In this work, we intend to systematize evidence on the philosophical definitions and neurobiological correlates of evil, and reflect on its implications in clinical psychiatry.
Methods
Literature review.
Results
The concept of evil has been a theme of debate since the ancient Greek, where Plato argued that evil was a result of ignorance and Aristoteles saw morality as a guide for education and politics. Nietzsche claimed that evil was a dangerous concept that was created by the church, while Hannah Arendt underlined the banality of evil by highlighting “thoughtlessness” that frequently justify evil acts. From a neurobiological perspective, studies assessing individuals with neuro-psychiatric conditions associated with evil-related behavioral abnormalities have been suggesting a potential role of frontal and limbic structures, as well as of the serotonergic system. However, several of these studies assessed presumed correlates of evil, such as antisocial personality disorder or impulsive-aggressive behavior.
Conclusions
Despite the polemic frontier between neurosciences and morality, a conceptual insight over the definition of evil is vital to guide comprehensiveness and clinical approach when dealing with deviant evil-like behaviors.

Abstract
IntroductionObsessive compulsive disorder (OCD) affects 2-3% of the general population. The neurobiology of OCD has been linked to dysfunction of cortico-striatal circuits connecting the orbitofrontal (OFC) to the striatum. Recently, this loop has become an approved target for non-invasive neuromodulatory treatment of OCD.ObjectivesTo explore structural and functional connectivity of the OFC in OCD subjects and healthy controls.Methods14 OCD patients and 12 age/sex-matched controls underwent magnetic resonance imaging (MRI) (3T-Philips scanner) for diffusion tensor imaging (DTI) and resting state functional connectivity (rsFC). DTI images were brain extracted and corrected for movement and eddy currents. A diffusion tensor model was fitted to each voxel and used to generate Fractional Anisotropy (FA) maps. Voxel-wise statistical analysis of FA was performed using Tract-Based Spatial Statistics. RsFC images were preprocessed and seed-based correlation (SBC) analysis was performed using Data Processing Assistant for Resting-State fMRI.ResultsWe found decreased values of FA in the body of the Corpus Callosum bilaterally (MNI_coordinates: x= 16, y= -16, z= 33 and x= -19, y= -16, z= 42) and left superior longitudinal fasciculus in OCD patients (fig 1, left), as well as decreased rsFC of the right superior orbitofrontal seed with the left inferior frontal gyrus and left middle occipital gyrus (fig 2, right).ConclusionsUsing an exploratory multimodal approach we found evidence of abnormal structural and functional long-range connectivity of the OFC in OCD. If confirmed in a larger sample these connectivity abnormalities could be explored as potential predictors of response to OFC-targeted non-invasive neuromodulatory interventions.DisclosureNo significant relationships.

Abstract
Introduction Obsessive-Compulsive Disorder (OCD) is an incapacitating Neuropsychiatric condition characterized by the presence of obsessions and/or compulsions. Although the disorder’s phenotype is well described, its pathophysiology remains elusive (Aouizerate et al, 2004). Over the last decade, techniques to noninvasively study the brain’s neurophysiology, such as Transcranial Magnetic Stimulation (TMS), have found widespread use in psychiatric research. For OCD, single- and paired-pule TMS protocols have been used to explore abnormalities in motor cortex excitability and cortical neuroplasticity. Here we propose to systematically review and, where possible, metanalyse existing case-control studies that compared such measures in patients and healthy subjects. Objectives To systematically review and meta-analyse published case-control studies comparing cortical excitability measures, as measured by single- or paired-pulse TMS, in subjects with OCD and healthy controls. Methods We have conducted a systematic review of published literature (PROSPERO registration CRD42020201764) reporting measures of cortical excitability as measured by single or paired-pulse TMS, in patients with OCD and healthy controls. We searched 4 different electronic libraries (PubMed, Web of Science, EMBASE, PsycINFO). The resulting list of articles was reviewed, separately, by two researchers. Disagreements were discussed and resolved by consensus, until a final list of eligible articles was obtained. Results 13 studies reporting motor cortex excitability measures were included in our final list. The total number of participants included in our analyses is 615 (349 OCD; 180 healthy subjects; 86 other conditions) Conclusions A sufficient number of studies was found to allow for metanalyses, currently ongoing.

Abstract
Introduction: The aim of this study was to explore the mediating effect of psychopathology between childhood adversity and trauma and quality of life (QOL) in adolescents. The second aim of the study was testing the moderation by social support of this mediation effect. Methods: Self-reports of childhood adversity and trauma, QOL, social support, and psychopathology were collected from 150 Portuguese adolescents' who had been exposed to at least one traumatic event or one childhood adversity (M age = 16.89, SD = 1.32). The surveys were administered at two time points with an approximate time interval of 1 year. Results: Indirect effects were observed for depression (B = -0.33, CI [-0.62, -0.11]), somatization (B = -0.52, CI [-0.82, -0.23]), and post-traumatic stress symptoms (PTSS) (B = -0.23, CI [-0.45, -0.01]), but not for anxiety (B = 0.20, CI [-0.08, 0.50]). A moderated mediation was found between social support and depression (B = -0.10, CI [-16, -0.04]), and PTSS (B = 0.03, CI [-0.1, -0.05]), but not for somatization (B = -0.02, CI [-0.8, 0.05]). Conclusions: We found that depression and somatization were strong mediators of the relationship between adversity/trauma and QOL, whereas PTSS was moderately mediated this relationship. Anxiety did not mediate this relationship. The moderated-mediation effect of social support was only found for depression and PTSS. The improvement of QOL in adolescents exposed to childhood adversity and trauma should include the assessment of psychopathology symptoms and social support, with the aim of identifying risk and protective factors.

Abstract
OBJECTIVE Obsessive-compulsive disorder (OCD) is a chronic, prevalent, and highly impairing psychiatric illness. Although the pathophysiology of OCD remains unknown, pathways involved in oxidative and nitrosative stress (O&NS) have been implicated. The present study aims to systematically review the literature for quantitative evidence that patients with OCD have altered measures of blood O&NS markers. METHODS Independent random-effects meta-analyses using standardized mean differences were conducted to assess each marker separately. Additionally, data from multiple markers were pooled together in a meta-analysis for measures of oxidant activity and another for measures of antioxidant activity. RESULTS Thirteen studies met inclusion criteria, involving 433 OCD patients and 459 controls. Eleven blood O&NS markers were eligible for independent quantitative analyses. We found that, in OCD patients, the oxidant markers 8-hydroxydeoxyguanosine and malondialdehyde, and the antioxidants glutathione peroxidase and superoxide dismutase, were significantly increased while total antioxidant status, vitamin C, and vitamin E were significantly decreased, when comparing with controls. Regarding pooled meta-analyses, we found a statistically significant increase in oxidant markers, but non-significant results regarding antioxidant markers. CONCLUSIONS Our meta-analysis suggests that OCD patients have a systemic oxidative imbalance that is not adequately buffered by the antioxidant system. Additional studies are needed in order to support this association.

Abstract
Water quality of Douro and Ave lower basin was evaluated regarding physicochemical parameters (pH, conductivity, dissolved oxygen and temperature), nutrient compounds (nitrates, nitrites, ammonium and orthophosphates), chlorophyll a and occurrence of trace elements (Li, Be, Al, Ti, V, Cr, Co, Ni, Cu, Zn, Se, Mo, Ag, Cd, Sb, Ba, Tl, Pb, Th and U). To study spatiotemporal variations and possible anthropogenic sources, estuarine samples were collected at nine sampling sites in Douro and five in Ave distributed along the estuaries at four sampling campaigns (spring, summer, fall and winter). According to the water quality standards for aquatic life and recreation, Douro and Ave river water quality was found out of safe limits regarding several parameters. Nitrate levels were systematically high (> 50 mg L-1 in a significant number of samples) and mean levels of trace elements were higher than the established values of Canadian Environmental Quality Guidelines for aquatic life protection for Al, Cu, Se, Ag, Cd and Pb in Douro and Ave, and also Zn in Ave. Significant spatial differences were found in Ave river estuary for trace elements with a clear trend for higher values from upstream to downstream found. Seasonal differences were also observed particularly in Douro river estuary with higher levels in spring for most elements.

Abstract
OBJECTIVES Several studies indicate that general practitioners (GPs) are not taking the issue of obesity as seriously as they should. Therefore, the aim of this study was to understand GPs' views about obesity and obese people and how these professionals perceive their role in the treatment of this disease. STUDY DESIGN Qualitative study using semi-structured interviews. METHODS Sixteen semi-structured interviews were conducted with Portuguese GPs. Data were analyzed according to thematic analysis procedures. RESULTS GPs are negative about their own role in obesity treatment. Although they believe it is part of their job to advise obese patients on the health risks of obesity, the majority of doctors think they are not making any difference in getting their patients to make long term lifestyle changes. GPs hold negative attitudes towards these patients blaming them for being unmotivated and non-compliant and are also pessimistic about their ability to lose weight. Doctors are facing a dilemma in their practices: they want to play an active role but, due to a set of negative beliefs and perceived barriers, they are playing a relatively passive role, feeling defeated and unmotivated, which is reflected in a decrease of efforts and a willing to give up on most of the cases. CONCLUSIONS This issue should be taken in to account during physicians' education since doctors should be aware of how their own beliefs and attitudes influence their behaviour and practices, compromising, therefore, the adherence to and the success in obesity treatment. They seem to need more precise guidelines and better tools for screening and management of obesity, more referral options, and improved coordination with other specialities.

Abstract
BACKGROUND Investigations conducted with several U.S. and U.K. military veterans returning from Afghanistan and Iraq have reported the existence of mental and physical health complaints. METHODS A total of 113 participants completed a self-report questionnaire that assessed post-traumatic stress disorder (PTSD) symptoms, physical health complaints, and reported illnesses. RESULTS Overall, 2.7% of the participants reported symptoms compatible with a PTSD diagnosis and 8.8% have partial PTSD. The most common physical health complaints were back pain, fatigue, and muscle pain. In addition, participants experienced gastrointestinal, nervous, and respiratory diseases. PTSD symptoms further explain the variance in physical health complaints after controlling for the contribution of reported illnesses to the same variables. CONCLUSIONS The prevalence of PTSD in the study sample is low, but PTSD symptoms are significantly related to physical health complaints and reported illnesses and explain the variance in physical symptoms. This fact should be considered by clinical support services, and military personnel with physical complaints should be screened for PTSD. These Portuguese results obtained from participants belonging to a well-prepared Special Operations Forces group contribute to a better understanding of the physical and mental impact of the war in Afghanistan.

Abstract
The relationship between war exposure and post-traumatic stress disorder (PTSD) has been largely investigated but the impact of the combat experience on physical health has only recently merited attention. The authors investigated the relationship between war exposure and psychological and physical health among 350 Portuguese colonial war veterans. The role of current PTSD symptoms as a mediator of these relationships was also investigated. The results showed that 39% of the veterans met criteria for current PTSD diagnosis and psychological distress was present in half of the sample. Pain, fatigue, and sleep problems were the most reported physical symptoms and mental health and gastro-intestinal problems, the most reported illnesses. Combat exposure variables were significant predictors of current health. The results indicated that veterans with higher exposure to war trauma maintained higher current levels of psychological distress and presented more physical health problems and physical symptoms than those less exposed. Mediation analyses showed that current PTSD was a full mediator of the relationship between war exposure and physical health outcomes.

Abstract
Research has shown that morbid obesity adults have more adverse childhood experiences. The aim of our work was to study the prevalence of this experience in a sample with 75 participants with morbid obesity (weight range of 118.57 Kg) candidate to bariatric surgery. Sixty-six (88%) participants had at least one adverse childhood experience, 51 (68%) refer at least four adverse experiences. The results suggest that a large number of participants had adverse childhood experiences, and food behaviour should be understood attending to the whole life of the individual.

Abstract
Estuaries are among the most productive ecosystems and simultaneously among the most threatened by conflicting human activities which damage their ecological functions, namely their nursery role for many fish species. A thorough assessment of the anthropogenic pressures in Portuguese estuarine systems (Douro, Ria de Aveiro, Mondego, Tejo, Sado, Mira, Ria Formosa and Guadiana) was made applying an aggregating multi-metric index, which quantitatively evaluates influences from key components: dams, population and industry, port activities and resource exploitation. Estuaries were ranked from most (Tejo) to least pressured (Mira), and the most influential types of pressure identified. In most estuaries overall pressure was generated by a dominant group of pressure components, with several systems being afflicted by similar problematic sources. An evaluation of the influence of anthropogenic pressures on the most important sparidae, soleidae, pleuronectidae, moronidae and clupeidae species that use these estuaries as nurseries was also performed. To consolidate information and promote management an ecological conceptual model was built to identify potential problems for the nursery function played by these estuaries, identifying pressure agents, ecological impacts and endpoints for the anthropogenic sources quantified in the assessment. This will be important baseline information to safeguard these vital areas, articulating information and forecasting the potential efficacy of future management options.

Abstract
OBJECTIVE The study examines the self-reported prevalence of childhood physical and sexual abuse in a large sample of Portuguese parents. METHOD Nearly 1,000 parents (506 mothers and 426 fathers) were selected through public primary schools from the Northern area of Portugal. All completed the Portuguese version of the Childhood History Questionnaire (CHQ) [Journal of Family Violence 5 (1990) 15]. RESULTS Results show that the prevalence of abuse was 73%, but more severe physical abuse involving sequelae/injury was reported by 9.5%. Most physical abuses began prior to age 13, with half continuing after age 13. No gender differences were found for rates of physical abuse. However, among the milder physical abuse without sequelae/injury, those women who experienced "whipping" or "slapping/kicking" were more likely to do so from their mothers than fathers. Among men who were "slapped/kicked" this was more likely to be from their fathers. Low rates of sexual abuse were found at 2.6% with no gender or age differences. Lack of a supportive adult in childhood related to the more severe abuses, but only in adolescence. Portuguese rates of abuse were consistently lower than those reported in USA and Spanish studies using the CHQ. CONCLUSIONS This is the first retrospective, self-report study of childhood abuse in a large sample of Portuguese parents and, even with a participation rate of 69%, shows lower rates than in US and Spanish samples.

Abstract
Metal ion electrophilic catalysis has been revealed in dealkylation reactions of phosphinic esters 1-4 promoted by complexes of polyether ligands 5-7 with metal iodides MI(n) (M[n+] = Li(+), Na(+), K(+), Rb(+), Ca(2+), Sr(2+), Ba(2+)) in low polarity solvents (chlorobenzene, 1,2-dichlorobenzene, and toluene) at 60 degrees C. The catalytic effect increases with increasing the Lewis acid character of the cation, in the order Rb(+)< K(+)< Na(+)< Li(+) and Ba(2+)< Sr(2+)< Ca(2+). The results are interpreted in terms of a transition state where the complexed cation (M[n+] subset Lig) assists the departure of the leaving group Ph(2)P(O)O(-) and, at the same time, favors the attack at carbon of the nucleophile I(-) ("push-pull" mechanism). The rate sequence found for 1-4 (Me > Et >> i-Pr and t-Bu) shows that this reaction can be utilized for the selective dealkylation of these substrates.

Abstract
UNLABELLED The city of Recife, northeastern Brazil, is reported to have the highest incidence of cervical cancer worldwide (83.2/100000 women). OBJECTIVE To evaluate the efficacy of Hybrid Capture I (HC I) in cervical cancer detection and some risk factors in Recife. METHOD Cervical scrapes for HC I analysis followed by colposcopy were collected from 140 women (70 with cervical cancer and 70 with normal cervix) from three screening services in Recife. RESULT HC I sensitivity and specificity were 82.9 and 41.4%, respectively. The odds ratios for cervical cancer when Gesta > or = 5 and vaginal parity > or = 4 were, respectively, 5.30 and 4.27. CONCLUSION HC I is a moderately sensitive method to detect cervical cancer, but it does not seem to be useful as a primary screening tool for it's low specificity. Early pregnancy, high Gesta/Para and living in rural areas were important local risk factors.

Abstract
OBJECTIVE Recent epidemiological and clinical data suggest that obsessive-compulsive disorder (OCD) may be subtyped according the age of onset of obsessive-compulsive symptoms. The regional cerebral blood flow (rCBF) single photon emission computed tomography (SPECT) technique was used to investigate whether the pathophysiology of OCD differs between early- and late-onset OCD subjects. METHOD Resting rCBF was measured in 13 early-onset (<10 years) and 13 late-onset (>12 years) adult OCD subjects and in 22 healthy controls. Voxel-based rCBF comparisons were performed with statistical parametric mapping. RESULTS Early-onset OCD cases showed decreased rCBF in the right thalamus, left anterior cingulate cortex, and bilateral inferior prefrontal cortex relative to late-onset subjects (p < .0005, uncorrected for multiple comparisons). Relative to controls, early-onset cases had decreased left anterior cingulate and right orbitofrontal rCBF, and increased rCBF in the right cerebellum, whereas late-onset subjects showed reduced right orbitofrontal rCBF and increased rCBF in the left precuneus. In early-onset subjects only, severity of obsessive-compulsive symptoms correlated positively with left orbitofrontal rCBF. CONCLUSIONS rCBF differences in frontal-subcortical circuits between early-onset and late-onset OCD subjects were found, both in location and direction of changes. These results provide preliminary evidence that brain mechanisms in OCD may differ depending on the age at which symptoms are first expressed.

Abstract
In a community sample of 102 Portuguese white women we evaluated the relationship between osteoporosis and indexes of psychopathology and well-being. Depressive symptoms were assessed by the Beck Depression Inventory (BDI), psychopathology by the Hopkins Symptom Checklist-90 Revised (SCL-90-R), and quality of life using the Psychological General Well-Being Index. A questionnaire comprising social, demographic, clinical, and behavioral characteristics was also used. The sample prevalence of osteoporosis was 47.1%. Women with osteoporosis presented significantly higher scores on the total BDI (16+/-9 vs. 13+/-10, p=0.045) and lower scores in the hostility (0.8+/-0.6 vs. 1.2+/-0.7, p=0.012) and phobic anxiety (1.1+/-0.8 vs. 1.5+/-0.9, p=0.041) subscales of the SCL-90-R. No differences were found regarding mean general well-being scores (62+/-17 vs. 64+/-19, p=0.665). This study showed that women with osteoporosis have significantly higher levels of depressive symptoms and a corresponding higher prevalence of depression, independent of other factors strongly associated with osteoporosis, such as age or body mass index.

Abstract
In the amphibian Xenopus laevis, adaptation of the skin color to background light intensity is regulated by alpha-melanophore-stimulating hormone (alpha-MSH), a proopiomelanocortin (POMC)-derived peptide. In animals adapted to a white background, the level of POMC biosynthesis in the intermediate pituitary is much lower than in animals adapted to a black background. Release of alpha-MSH from neurointermediate lobes of white-adapted animals is stimulated in vitro by the regulatory peptides sauvagine and thyrotropin-releasing hormone (TRH), which are produced in the magnocellular nucleus of the hypothalamus. To study the role of sauvagine, cAMP, TRH and phorbol 12-myristate 13-acetate (PMA) in the regulation of POMC biosynthesis, the degree of incorporation of radioactive amino acids into the POMC protein was determined after treatment of the neurointermediate lobes with these secretagogues. When lobes of white-adapted animals are incubated in vitro, biosynthetic activity spontaneously increases because hypothalamic inhibitory control is removed by dissection. In addition to this control situation, the effects of secretagogues were tested on lobes with an inhibited level of biosynthesis, which is achieved by addition of neuropeptide Y (NPY) to the incubation medium. After 24 h of treatment, TRH stimulated POMC biosynthesis in NPY-inhibited lobes of white-adapted animals from 40.2 to 95.3% of control level. This stimulation could not be reduced by adding PMA, which indicates that protein kinase C is not involved in the stimulation of POMC biosynthesis by TRH. Sauvagine partially restored POMC biosynthesis from 27.2 to 62.5% of control level, whereas 8-Br-cAMP completely counteracted NPY inhibition from 27.8 to 97.5% of control level. After 3 days of treatment, stimulation by sauvagine and 8-Br-cAMP was maintained (sauvagine increased POMC biosynthesis in NPY-inhibited lobes from 7.4 to 36.2% of control level and 8-Br-cAMP stimulated from 6.5 to 82.5% of control level). TRH had no effect on POMC biosynthesis after 3 days of treatment, although its receptor was still functional as was shown in superfusion experiments where TRH stimulated alpha-MSH secretion. The observations indicate that the neuropeptides sauvagine and TRH differently control POMC biosynthesis in the Xenopus intermediate pituitary. This differential regulation is not only apparent with regard to time aspects (sauvagine has a sustained regulatory function, whereas TRH is only effective in the initial phase of POMC biosynthesis stimulation), but also an uncoupling of biosynthetic and release processes could be shown for TRH, which did not occur with sauvagine.
