Catechol-O-methyltransferase activity in individuals with substance use disorders: a case control study.

BACKGROUND: Impulsivity and substance use disorders (SUD) have been both associated with changes in dopaminergic processes. In this study, we intended to evaluate the dopaminergic function in imprisoned SUD offenders through the determination of s-COMT activity. METHODS: The study included 46 male individuals from a Portuguese penal institution. The participants were assessed through a battery of standardised instruments: Psychopathy Checklist-Revised (PCL-R), Barratt Impulsivity Scale Version 11 (BIS-11), and the European version of the Addiction Severity Index (EuropASI). In addition, s-COMT erythrocyte activity was evaluated. RESULTS: Overall, 73.9% (n = 34) of the individuals had Antisocial personality disorder (ASPD) and 58.7% (n = 27) presented SUD. We evidenced, for the first time, that, in individuals with SUD, s-COMT activity was correlated with the severity of drug dependence (EuropASI) (p = 0.009), and with BIS-11 factors self-control (p < 0.0001) and non-planning (p = 0.002). CONCLUSIONS: This study opens new perspectives regarding the pharmacological intervention on substance dependence through the interference on dopamine pathways.

The role of marine omega-3 in human neurodevelopment, including Autism Spectrum Disorders and Attention-Deficit/Hyperactivity Disorder - a review.

Autism Spectrum Disorders (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are two increasingly prevalent neurodevelopmental disorders. This rise may be associated with a higher dietary intake of n-6 polyunsaturated fatty acids (PUFAs) and lower of n-3 PUFAs. Docosahexaenoic acid (DHA), a key nutritional n-3 PUFA, is crucial for an optimal offspring's neurodevelopment through the last trimester of pregnancy. Recently, lower DHA levels have been reported in children with ASD and ADHD. The present review summarizes the main research achievements concerning the effect of DHA in children neurodevelopment, in order to elicit its role in the prevention and mitigation of ASD and ADHD. As main finding, a low DHA supply seems to negatively affect childhood neurodevelopment in specific conditions and increase the risk and the severity of ASD or ADHD. Higher DHA status at birth was associated with better childhood neurodevelopmental, but controversial results found in prenatal supplementation raised the hypothesis that the benefits of DHA may be influenced by other factors as socio-economic background and life-style. In conclusion, an optimal DHA provision through maternal diet or breastfeed may promote some neuronal protection in specific offspring's populations, suggesting that DHA may act as a modifiable risk factor for ASD and ADHD.

Oxytocin and depression in the perinatal period-a systematic review.

Postpartum depression (PPD) is the most common postnatal psychiatric disorder, and it represents a considerable problem to the health and well-being of women and their families. Several pathogenic mechanisms have been identified in PPD, and recently, oxytocin (OT), known to be involved in childbirth and lactation, has drawn attention as a possible diagnostic and therapeutic tool in this disorder. The aim of this review was to assess and summarize the current literature on the relationship between OT as a potential depressive biomarker and depression in the perinatal period. We conducted a literature search on four electronic databases (Pubmed, PsycINFO, Web of Science, and Science Direct) by applying the following search terms: oxytocin AND (postpartum OR postnatal OR perinatal OR peripartum) AND (depression OR depressive). Six studies were included and a total of 620 pregnant women were recruited and completed the follow-up. Depressive symptoms were evaluated using self-report scales, and in three studies, the diagnosis of major depression was additionally confirmed using semi-structured interviews. Peripheral OT levels and depression were assessed during pregnancy and/or after delivery. Higher OT levels were associated with lower depressive symptoms, even if this association lacked statistical significance in two studies. Although some studies are beginning to shed light upon the complex nature of OT's effect in depression, its role as a diagnostic and therapeutic tool in PPD is still unclear. Future research is needed to clarify the neuroendocrinological and psychosocial particularities of mothers with PPD and to define a specific profile associated with OT dysfunction.

Adherence to APAP in obstructive sleep apnea syndrome: effectiveness of a motivational intervention.

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is a serious disorder with significant health consequences. Treatment adherence to auto-titrating positive airway pressure (APAP) is often below expectations. We investigated the effectiveness of a brief educational intervention using motivational strategies in treatment adherence among patients with OSAS. METHODS: The study followed a randomized, controlled design and included 61 patients diagnosed with OSAS, meeting the criteria for APAP therapy. Patients recruited from a Sleep Disorders Unit were randomly allocated to an intervention group (IG) and two control groups (CG1 and CG2). In the IG motivational strategies were applied according to patient's motivation, assessed by the degree of confidence and conviction. In the CG1, participants received exclusively standardized information, and in the CG2, routine procedures were followed. Assessment included the Apnea Hypopnea Index (AHI), the Epworth Sleepiness Scale (ESS), and sociodemographic and clinical information. Adherence to treatment was measured after 1 (T1) and 2 months (T2) through the APAP software. RESULTS: The IG presented higher adherence to APAP-percentage of days of use >4 h (89.8 % p = 0.013), mean effective use per effective day (6.2 p = 0.000), and lower AHI (2.7 p = 0.019) at T2 when compared with the other two groups. Confidence was higher in the IG group at T2 than at T1 (p = 0.000). The ESS presented a significant reduction (p = 0.000) in the IG and in the CG1 (p = 0.008), but was higher in the CG2 (p = 0.015). CONCLUSIONS: Brief interventions using motivational strategies can improve a patient's adherence to APAP.

Teaching communication skills in clinical settings: comparing two applications of a comprehensive program with standardized and real patients.

BACKGROUND: Communication is important for the quality of clinical practice, and programs have been implemented to improve healthcare providers' communication skills. However, the consistency of programs teaching communication skills has received little attention, and debate exists about the application of acquired skills to real patients. This study inspects whether (1) results from a communication program are replicated with different samples, and (2) results with standardized patients apply to interviews with real patients. METHODS: A structured, nine-month communication program was applied in two consecutive years to two different samples of healthcare professionals (25 in the first year, 20 in the second year). Results were assessed at four different points in time, each year, regarding participants' confidence levels (self-rated), basic communication skills in interviews with standardized patients, and basic communication skills in interviews with real patients. Data were analyzed using GLM Repeated-Measures procedures. RESULTS: Improvements were statistically significant in both years in all measures except in simulated patients' assessment of the 2008 group. Differences between the two samples were non-significant. Differences between interviews with standardized and with real patients were also non-significant. CONCLUSIONS: The program's positive outcomes were replicated in different samples, and acquired skills were successfully applied to real-patient interviews. This reinforces this type of program structure as a valuable training tool, with results translating into real situations. It also adds to the reliability of the assessment instruments employed, though these may need adaptation in the case of real patients.

A longitudinal study of risk and protective factors for symptoms of adjustment disorder during the COVID-19 pandemic.

Background: The COVID-19 pandemic caused multiple stressors that may lead to symptoms of adjustment disorder.Objective: We longitudinally examined relationships between risk and protective factors, pandemic-related stressors and symptoms of adjustment disorder during the COVID-19 pandemic, as well as whether these relationships differed by the time of assessment.Method: The European Society for Traumatic Stress Studies (ESTSS) ADJUST Study included N = 15,169 participants aged 18 years and above. Participants from 11 European countries were recruited and screened three times at 6-month intervals from June 2020 to January 2022. Associations between risk and protective factors (e.g. gender), stressors (e.g. fear of infection), and symptoms of adjustment disorder (AjD, ADNM-8) and their interaction with time of assessment were examined using mixed linear regression.Results: The following predictors were significantly associated with higher AjD symptom levels: female or diverse gender; older age; pandemic-related news consumption >30 min a day; a current or previous mental health disorder; trauma exposure before or during the pandemic; a good, satisfactory or poor health status (vs. very good); burden related to governmental crisis management and communication; fear of infection; restricted social contact; work-related problems; restricted activity; and difficult housing conditions. The following predictors were associated with lower AjD levels: self-employment or retirement; working in healthcare; and face-to-face contact ≥ once a week with loved ones or friends. The effects of the following predictors on AjD symptoms differed by the time of assessment in the course of the pandemic: a current or previous mental disorder; burden related to governmental crisis management; income reduction; and a current trauma exposure.Conclusions: We identified risk factors and stressors predicting AjD symptom levels at different stages of the pandemic. For some predictors, the effects on mental health may change at different stages of a pandemic.

We longitudinally examined predictors of symptoms of adjustment disorder in 15,563 adults during the COVID-19 pandemic.We found stressors, risk, and protective factors predicting adjustment disorder symptom levels at different stages of the pandemic.For some predictors, the effects appear to change in different phases of a pandemic.

Psychological burden in Portuguese university students during the COVID-19 pandemic.

Background: University students are a risk population for mental health problems. This study aims to evaluate the psychological burden of the COVID-19 pandemic in Portuguese university students and to uncover factors associated with worse psychological indicators. Methods: We used an online survey to perform a cross-sectional study that evaluated students' perceptions, lifestyle, and psychological well-being during the pandemic. Depression symptoms and risk were measured by the Patient Health Questionnaire-9, and resilience levels were quantified by the 9-item Resilience Evaluation Scale. Self-perceived levels of anxiety and current mental health status were evaluated. Results: From a population of around 30,000 students invited to participate, 1751 responses were obtained and 1447 were included. Most students were female (72.3%) and were taking a master's degree (58.4%). The course with more responses was engineering (25.5%), followed by medicine (13.2%). The prevalence rates for higher anxiety levels, depression risk, and low resilience levels were 66.7%, 37.3%, and 24.9%, respectively. The factors associated with better psychological outcomes were being male, spending more time studying, having a job, performing extracurricular activities, physical exercise, and relaxing activities. By contrast, spending more time watching news, difficulty accessing online lectures, and absence of contact with family or friends were associated with worse psychological indicators. Although all courses presented substantial levels of depressive symptoms, architectures/arts, sciences, and humanities scored significantly more in the depression scale. Medicine students had significantly higher resilience levels compared with other courses. Conclusions: Our findings identify factors associated with worse psychological outcomes and can be used to create protective measures for the mental health of university students during current and future pandemics.

Shaped by the COVID-19 pandemic: Psychological responses from a subjective perspective-A longitudinal mixed-methods study across five European countries.

BACKGROUND: Contextual factors are essential for understanding long-term adjustment to the COVID-19 pandemic. Therefore, the present study investigated changes in mental health outcomes and subjective pandemic-related experiences over time and across countries. The main objective was to explore how psychological responses vary in relation to individual and environmental factors. METHODS: The sample consisted of N = 1070 participants from the general population of Austria, Croatia, Georgia, Greece, and Portugal. We applied a longitudinal mixed-methods approach, with baseline assessment in summer and autumn 2020 (T1) and follow-up assessment 12 months later (T2). Qualitative content analysis by Mayring was used to analyse open-ended questions about stressful events, positive and negative aspects of the pandemic, and recommendations on how to cope. Mental health outcomes were assessed with the Adjustment Disorder-New Module 8 (ADNM-8), the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5), the Patient Health Questionnaire-2 (PHQ-2), and the 5-item World Health Organization Well-Being Index (WHO-5). The analyses were performed with SPSS Statistics Version 26 and MAXQDA 2022. RESULTS: The mental health outcomes significantly differed over time and across countries, with e.g. Greek participants showing decrease in adjustment disorder symptoms (p = .007) between T1 and T2. Compared with other countries, we found better mental health outcomes in the Austrian and the Croatian sample at both timepoints (p < .05). Regarding qualitative data, some themes were equally represented at both timepoints (e.g. Restrictions and changes in daily life), while others were more prominent at T1 (e.g. Work and finances) or T2 (e.g. Vaccination issues). CONCLUSIONS: Our findings indicate that people's reactions to the pandemic are largely shaped by the shifting context of the pandemic, country-specific factors, and individual characteristics and circumstances. Resource-oriented interventions focusing on psychological flexibility might promote resilience and mental health amidst the COVID-19 pandemic and other global crises.

Psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) in 9230 adults across seven European countries: Findings from the ESTSS ADJUST study.

BACKGROUND: The four-item Patient Health Questionnaire-4 (PHQ-4) is a widely used screening measure for depression and anxiety. OBJECTIVES: This study aimed to test factor structure and measurement invariance in an adult sample of the general population across seven European countries. METHOD: A total sample of 9230 adults, 71.3 % female, Mage = 44.35 (SD = 14.11) from seven countries (Austria, Croatia, Georgia, Germany, Lithuania, Portugal, and Sweden) participated in the study. We applied confirmatory factor analysis (CFA) to examine the factor structure and measurement invariance testing to evaluate measurement equivalence across countries, gender, and age groups. RESULTS: The CFA yielded that a two-factor PHQ-4 model with separate depression and anxiety factors had the best fit. Partial scalar measurement invariance was established across different groups based on gender, age, and country. CONCLUSIONS: The PHQ-4 is a valid and reliable measure that can be applied to screen for depression and anxiety in the general population. LIMITATIONS: The limitation of the study includes the sampling, which resulted in the sample structure with the majority of females, predominantly of high education and from urban communities.

Impact of a Digital Intervention for Literacy in Depression among Portuguese University Students: A Randomized Controlled Trial.

Digital interventions are important tools to promote mental health literacy among university students. "Depression in Portuguese University Students" (Depressão em Estudantes Universitários Portugueses, DEEP) is an audiovisual intervention describing how symptoms can be identified and what possible treatments can be applied. The aim of this study was to evaluate the impact of this intervention. A random sample of 98 students, aged 20-38 years old, participated in a 12-week study. Participants were recruited through social media by the academic services and institutional emails of two Portuguese universities. Participants were contacted and distributed into four study groups (G1, G2, G3 and G4): G1 received the DEEP intervention in audiovisual format; G2 was given the DEEP in text format; G3 received four news articles on depression; G4 was the control group. A questionnaire was shared to collect socio-demographic and depression knowledge data as a pre-intervention method; content was then distributed to each group following a set schedule; the depression knowledge questionnaire was then administered to compare pre-intervention, post-intervention and follow-up literacy levels. Using the Scheffé and Least Significant Difference (LSD) multiple comparisons test, it was found that G1, which received the DEEP audiovisual intervention, differed significantly from the other groups, with higher depression knowledge scores in post-intervention stages. The DEEP audiovisual intervention, compared to the other formats used (narrative text format; news format), proved to be an effective tool for increasing depression knowledge in university students.

Communication skills preparedness for practice: Is there a key ingredient in undergraduate curricula design?

OBJECTIVE: To characterize medical interns' experience regarding communication skills education and to explore potential associations with preparedness for practice. METHODS: Two hundred sixty-six medical interns answered an original questionnaire specifically developed to explore how well they feel their undergraduate training had prepared them in key aspects of medical communication. Instrument's psychometric properties were tested. Medical schools' curricula were considered and associations explored using non-parametric tests. RESULTS: The questionnaire reliability was high, with Cronbach's alphas ranging from 0.89 to 0.94 on all the factors. Core communication skills were highly rated. Perceived preparedness was lower in aspects concerning dealing with emotion, breaking bad news and communicating with speech impaired patients. Better preparedness was associated with a longitudinal integration of communication skills throughout the curriculum, simulation with standardized patients and real patient interviewing with feedback on communication skills. CONCLUSIONS: Integrated programs, standing on a strong experimental component, particularly combining patient-simulation strategies with continuous supervision and learner centred feedback, were associated with higher preparedness. These results support the expansion of an educational model based on simulation strategies and structured longitudinally throughout the undergraduate medical curriculum. PRACTICE IMPLICATIONS: This study intends to inform educational background and to support further development of communication skills curricula.

You can't do anything about it, but you can make the best of it: a qualitative analysis of pandemic-related experiences in six European countries.

Background: The complex system of stressors related to the coronavirus disease 2019 (COVID-19) pandemic has affected the global population, provoking a broad range of psychological reactions. Although numerous studies have investigated the mental health impact of COVID-19, qualitative research and cross-country comparisons are still rare. Objective: This qualitative study aimed to explore self-perceived challenges and opportunities related to COVID-19 across six European countries. The overall objective was to provide a differentiated picture of individual subjective experiences in the early stages of the pandemic. Method: The present study included 7309 participants from Austria, Croatia, Georgia, Greece, Poland, and Portugal. We performed qualitative content analysis according to Mayring analyse open-ended questions regarding stressful events, positive and negative aspects of the pandemic, and recommendations to cope with the pandemic situation. MAXQDA software was used for data management and analysis. Results: Participants' accounts were moderately consistent across the countries. The most prominent themes regarding stressful and negative pandemic aspects included: Restrictions and changes in daily life, Emotional distress, and Work and finances. Answers about positive pandemic consequences were mainly centred around the themes Reflection and growth, Opportunity for meaningful/enjoyable activities, and Benefits on interpersonal level. Key themes identified from participants' recommendations to cope with the pandemic included Beneficial behavioural adjustment, Beneficial cognitive-emotional strategies, and Social support. Conclusions: Participants experienced various challenges, but also shared several positive pandemic consequences and recommendations to cope with the pandemic. These first-hand data could inform mental health practices to promote well-being during COVID-19 and similar global challenges in the participating countries and possibly beyond. HIGHLIGHTS: We examined COVID-19-related experiences in 7309 adults from six European countries.Besides challenges, participants identified many positive pandemic consequences.Participants' recommendations to cope with COVID-19 included behavioural and cognitive-emotional strategies.

Risk and protective factors for posttraumatic stress disorder in trauma-exposed individuals during the COVID-19 pandemic - findings from a pan-European study.

HIGHLIGHTS: N = 4,607 trauma-exposed adult participants were recruited from the general population during the first year of the COVID-19 pandemic.The prevalence for probable posttraumatic stress disorder was 17.7%.We identified risk factors (e.g. poor health condition) and protective factors (e.g. social contact) associated with posttraumatic stress disorder.

Obesity and gut microbiome: review of potential role of probiotics.

Obesity prevalence has increased worldwide over the years, with pandemic levels being already reached, besides to its huge economic and health impacts. The multifactorial pathogenesis of obesity partly explains the important challenge posed to health policy regarding its clinical treatment, with increasing evidences have shown that obesity and metabolic disturbances are closely linked to variations in gut microbiota (GM) function and composition. Indeed, GM play a key contribution in energy metabolism, with GM modulation being increasingly linked to changes in body weight and body mass index. In such matter, probiotics have been proposed as a promising new therapeutic strategy to treat/prevent obesity. Thus, this review aims to provide an overview on the clinical impact and effectiveness of probiotics in obese individuals.

Physicians privilege responding to emotional cues in oncologic consultations: A study utilizing Verona Coding Definitions of Emotional Sequences.

The aim of this study was to describe emotional cues and concerns expressed by cancer patients and their physicians using video-recorded regular oncology consultations. The consultations were divided into units of analysis and coded according to the Verona Coding Definitions of Emotional Sequences system. The study design was mixed, descriptive, and exploratory. Twelve patients and eight oncologists participated in the study. The patients expressed 349 cues/concerns during the 12 consultations. The majority (68.8%) of the content consisted of non-explicit description of physiological and stress episodes in the disease and treatment. Physicians demonstrated that they recognized fewer underlying cues than those related to physiological complaints.

Kidney Function, Age, and Education as Contributors to Depression and Anxiety in Juvenile Systemic Lupus Erythematosus.

Juvenile systemic lupus erythematosus (JSLE) is diagnosed in children younger than 18 years of age. Depression and anxiety are common, but not well understood in JSLE. We investigated the clinical and psychological factors associated with the psychological manifestations of JSLE. Twenty-nine JSLE patients were recruited for the study. Patients completed surveys evaluating their psychological status and perceptions about their health. Medical records were used to obtain laboratory results. The JSLE patient population was compared with adult-onset SLE (ASLE) patients and unaffected controls. Kidney involvement was associated with depression in the JSLE patients. The BUN levels, BUN/creatinine ratio, and leukocyturia were all significantly associated with depressive symptoms. Multivariate analysis found that the BUN/creatinine ratio was the most predictive value for both depression and anxiety. Depressive symptoms in JSLE were less pronounced than in ASLE, although anxiety was not different. Age and education are likely to be protective against depression in the JSLE patients. These findings may indicate that symptomatology is an important indicator of whether the patient needs psychiatric care.

Risk and protective factors, stressors, and symptoms of adjustment disorder during the COVID-19 pandemic - First results of the ESTSS COVID-19 pan-European ADJUST study.

Background: The COVID-19 pandemic exposes individuals to multiple stressors, such as quarantine, physical distancing, job loss, risk of infection, and loss of loved ones. Such a complex array of stressors potentially lead to symptoms of adjustment disorder. Objective: This cross-sectional exploratory study examined relationships between risk and protective factors, stressors, and symptoms of adjustment disorder during the first year of the COVID-19 pandemic. Methods: Data from the first wave of the European Society of Traumatic Stress Studies (ESTSS) longitudinal ADJUST Study were used. N = 15,563 participants aged 18 years and above were recruited in eleven countries (Austria, Croatia, Georgia, Germany, Greece, Italy, Lithuania, the Netherlands, Poland, Portugal, and Sweden) from June to November 2020. Associations between risk and protective factors (e.g. gender, diagnosis of a mental health disorder), stressors (e.g. fear of infection, restricted face-to-face contact), and symptoms of adjustment disorder (ADNM-8) were examined using multivariate linear regression. Results: The prevalence of self-reported probable adjustment disorder was 18.2%. Risk factors associated with higher levels of symptoms of adjustment disorder were female gender, older age, being at risk for severe COVID-19 illness, poorer general health status, current or previous trauma exposure, a current or previous mental health disorder, and longer exposure to COVID-19 news. Protective factors related to lower levels of symptoms of adjustment disorder were higher income, being retired, and having more face-to-face contact with loved ones or friends. Pandemic-related stressors associated with higher levels of symptoms of adjustment disorder included fear of infection, governmental crisis management, restricted social contact, work-related problems, restricted activity, and difficult housing conditions. Conclusions: We identified stressors, risk, and protective factors that may help identify individuals at higher risk for adjustment disorder.

Antecedentes: La pandemia de COVID-19 expone a las personas a múltiples factores estresantes, como la cuarentena, el distanciamiento físico, la pérdida del trabajo, el riesgo de infección, y la pérdida de seres queridos. Esta compleja serie de factores estresantes puede potencialmente conducir a síntomas del trastorno de adaptación.Objetivo: Este estudio exploratorio transversal examinó las relaciones entre los factores de riesgo y de protección, los factores estresantes, y los síntomas del trastorno de adaptación durante el primer año de la pandemia de COVID-19.Métodos: Se utilizaron datos de la primera ola del estudio longitudinal ADJUST de la Sociedad Europea de Estudios de Estrés Traumático (ESTSS en su sigla en inglés). N = 15.563 participantes de 18 años o más fueron reclutados en once países (Austria, Croacia, Georgia, Alemania, Grecia, Italia, Lituania, Países Bajos, Polonia, Portugal, y Suecia) de junio a noviembre de 2020. Se examinaron mediante regresión lineal multivariante las asociaciones entre los factores de riesgo y de protección (p. ej., género, diagnóstico de un trastorno de salud mental), factores estresantes (p. ej., miedo a la infección, contacto restringido cara a cara), y síntomas del trastorno de adaptación (ADNM-8 en su sigla en inglés).Resultados: La prevalencia del trastorno de adaptación probable autoinformado fue del 18,2%. Los factores de riesgo asociados con niveles más altos de síntomas del trastorno de adaptación fueron género femenino, edad avanzada, riesgo de enfermedad grave por COVID-19, peor estado de salud general, exposición a un trauma actual o anterior, un trastorno de salud mental actual o anterior, y una exposición más prolongada a las noticias de COVID-19. Los factores de protección relacionados con niveles más bajos de síntomas del trastorno de adaptación fueron mayores ingresos, estar jubilado, y tener más contacto cara a cara con sus seres queridos o amigos. Los factores estresantes relacionados con la pandemia que se asociaron con niveles más altos de síntomas del trastorno de adaptación incluyeron miedo a la infección, manejo gubernamental de crisis, contacto social restringido, problemas relacionados con el trabajo, actividad restringida, y condiciones de vivienda difíciles.Conclusiones: Identificamos factores estresantes, de riesgo, y protectores que pueden ayudar a identificar a las personas con mayor riesgo de trastorno de adaptación.

Putative shared mechanisms in autism spectrum disorders and attention deficit hyperactivity disorder, a systematic review of the role of oxidative stress.

Oxidative stress is now believed to play a crucial role for neurodevelopment disorders such as autism spectrum disorders (ASD) and attention deficit hyperactivity disorder (ADHD). To review the most recent literature regarding the role of oxidative stress for the pathophysiology of ASD and ADHD, we conducted a systematic search of the relevant literature and further discuss the clinical and research implications of this knowledge. A systematic search in PubMed database retrieved 132 articles, of which 33 were included in the review. This review found relevant evidence concerning the role of oxidative status in ASD and ADHD, albeit with some contradictory findings. In order to overcome the incongruities found, more studies are needed in the study of neurodevelopmental disorders, with more thorough study designs and particular attention to the accuracy of the diagnostic tools used for the cases included.

Impulsive and premeditated aggression in male offenders with antisocial personality disorder.

INTRODUCTION: Aggression is a clinical symptom of various psychiatric disorders that can be conceptualised as a physical act towards another person with the intent to cause harm. In antisocial personality disorder (ASPD), aggression is a frequent manifestation that differently compromise therapeutic and prognostic goals according to its impulsive or premeditated categorisation. ASPD is characterised by high levels of impulsivity, psychopathic traits, and a high prevalence of co-morbid substance use disorders (SUDs). Aggression in ASPD patients may determine long and recurrent imprisonment thus representing a challenge clinicians and legal experts face. OBJECTIVES: Our aims were to characterise impulsive and premeditated aggression in male ASPD offenders as well as to determine the potential role of SUDs, impulsivity, and psychopathic traits as predictors. MATERIALS AND METHODS: In this cross-sectional study we evaluated a sample of ASPD offenders with a battery of clinical and psychometric, standardised instruments: the Psychopathy Checklist-Revised (PCL-R), the European Version of the Addiction Severity Index (EuropASI), the Barratt Impulsivity Scale Version 11 (BIS-11), and the Impulsive/Premeditated Aggression Scale (IPAS). RESULTS: We used a total sample of 134 offenders, all of whom were male. ASPD patients (n = 96) had a 71.9% prevalence of impulsive aggression and a 28.1% prevalence of premeditated aggression. ASPD patients with impulsive aggression had significantly lower scores of total PCL-R (p<0.01) factor 1 and interpersonal facet 1 (p<0.05), compared with ASPD patients with premeditated aggression. ASPD patients with impulsive aggression and ASPD patients with premeditated aggression had comparable BIS-11 mean scores, and exhibited an equal prevalence of SUDs. The interpersonal facet 1of the PCL-R predicted the aggression type (p<0.05) in ASPD patients, and the exponential beta value for facet 1 was 1.42 (CI = 1.03; 1.95). CONCLUSIONS: The aggression type that is associated with ASPD is mainly impulsive in nature. ASPD patients who have higher scores of psychopathic traits have a lower probability of exhibiting impulsive aggression and a higher probability of exhibiting premeditated aggression. Although ASPD patients have high levels of impulsivity and a high frequency of SUDs, these two variables were not predictors of the aggression type.

Stressors, coping and symptoms of adjustment disorder in the course of the COVID-19 pandemic - study protocol of the European Society for Traumatic Stress Studies (ESTSS) pan-European study.

BACKGROUND: During the current COVID-19 pandemic, the people in Europe are exposed to self-isolation, quarantine, job loss, risk of contracting COVID-19, or grief of loved ones. Such a complex array of stressors may lead to symptoms of adjustment disorder or posttraumatic stress disorder. This research protocol describes a study launched by the European Society of Traumatic Stress Studies (ESTSS) to investigate the impact of the COVID-19 pandemic on symptoms of adjustment disorder across European countries. OBJECTIVE: The longitudinal online cohort study aims (1) to explore psychosocial reactions to the COVID-19 pandemic across ten European countries; (2) to examine the relationships between risk and resilience factors, stressors and symptoms of adjustment disorder during the pandemic; and (3) to investigate whether these relationships are moderated by coping behaviours. METHOD: In ten countries (Austria, Croatia, Georgia, Germany, Italy, Lithuania, Netherlands, Poland, Portugal, and Sweden), between 1,000 and 2,000 participants will be recruited, depending on the size of the country. Participants will be assessed at two timepoints with a six-month interval. Following a conceptual framework based on the WHO's social framework of health, an assessment of risk and resilience factors, COVID-19 related stressors and pandemic-specific coping behaviours will be measured to estimate their contribution to symptoms of adjustment disorder. The Adjustment Disorder New Module 8 (ADNM-8) will be used to assess symptoms of adjustment disorder. As a secondary measure, symptoms of posttraumatic stress disorder will be measure using the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5). DATA ANALYSIS: The relative contribution of risk factors, resilience factors, and stressors on symptoms of adjustment disorder or symptoms of posttraumatic stress disorder will be estimated using multilevel analysis. To determine the moderating effects of different types of coping behaviours on these relationships, a multilevel mediation analysis will be carried out.

Antecedentes: Durante la actual pandemia de COVID-19, las personas en Europa están expuestas a autoaislamiento, cuarentena, pérdida de empleo, riesgo de contraer COVID-19 o duelo de sus seres queridos. Un conjunto tan complejo de factores estresantes puede provocar síntomas de trastorno de adaptación o trastorno de estrés postraumático. Este protocolo de investigación describe un estudio lanzado por la Sociedad Europea de Estudios de Estrés Traumático (ESTSS) para investigar el impacto de la pandemia COVID-19 en los síntomas del trastorno de adaptación en países europeos.Objetivo: El estudio longitudinal de cohorte en línea tiene como objetivo (1) explorar las reacciones psicosociales a la pandemia de COVID-19 en diez países europeos; (2) examinar las relaciones entre los factores de riesgo y resiliencia, estresores y síntomas de trastorno de adaptación durante la pandemia; e (3) investigar si estas relaciones son moderadas por comportamientos de afrontamiento.Método: En diez países (Austria, Croacia, Georgia, Alemania, Italia, Lituania, Países Bajos, Polonia, Portugal y Suecia) serán reclutados entre 1,000 y 2,000 participantes, dependiendo del tamaño del país. Los participantes serán evaluados en dos momentos con un intervalo de seis meses. Siguiendo un marco conceptual basado en el marco social de salud de la OMS, una evaluación de los factores de riesgo y resiliencia, factores estresantes relacionados con COVID-19 y el comportamiento de afrontamiento específico de la pandemia serán medidos para estimar su contribución a los síntomas de trastorno de adaptación. El nuevo módulo de trastorno de adaptación 8 (ADNM-8) se utilizará para medir los síntomas del trastorno de adaptación. Como medida secundaria, se evaluarán síntomas de trastorno de estrés postraumático usando el cribaje de TEPT en atención primaria para DSM-5 (PC-PTSD-5).Análisis de datos: La contribución relativa de los factores de riesgo, factores de resiliencia y los estresores sobre los síntomas de trastorno de adaptación o síntomas de trastorno de estrés postraumático se estimará mediante análisis multinivel. Para determinar los efectos moderadores de diferentes tipos de conductas de afrontamiento en estas relaciones, se llevará a cabo un análisis de mediación multinivel.
