Abstract
Several anticancer therapies have the potential to cause infusion-related reactions (IRRs) in the form of adverse events that typically occur within minutes to hours after drug infusion. IRRs can range in severity from mild to severe anaphylaxis-like reactions. Careful monitoring at infusion initiation, prompt recognition, and appropriate clinical assessment of the IRR and its severity, followed by immediate management, are required to ensure patient safety and optimal outcomes. Lack of standardization in the prevention, management, and reporting of IRRs across cancer-treating institutions represents not only a quality and safety gap but also a disparity in cancer care. The present article, supported by recently published data, was developed to standardize these procedures across institutions and provide a useful tool for health care providers in clinical practice to recognize early signs and symptoms of an IRR and promptly and appropriately manage the event.

Abstract
INTRODUCTION The management of unresectable stage III non-small cell lung cancer (NSCLC) is clinically challenging and there is no current consensus on optimal strategies. Herein, a panel of Portuguese experts aims to present practical recommendations for the global management of unresectable stage III NSCLC patients. METHODS A group of Portuguese lung cancer experts debated aspects related to the diagnosis, staging and treatment of unresectable stage III NSCLC in light of current evidence. Recent breakthroughs in immunotherapy as part of a standard therapeutic approach were also discussed. This review exposes the major conclusions obtained. RESULTS Practical recommendations for the management of unresectable stage III NSCLC were proposed, aiming to improve the pathways of diagnosis and treatment in the Portuguese healthcare system. Clinical heterogeneity of patients with stage III NSCLC hinders the development of single standardised algorithm where all fit. CONCLUSIONS A timely diagnosis and a proper staging contribute to the best management of each patient, optimizing treatment tolerance and effectiveness. The expert panel considered chemoradiotherapy as the preferable approach when surgery is not possible. Management of adverse events and immunotherapy as a consolidation therapy are also essential steps for a successful strategy.

Abstract
Understanding the structure of food competition between conspecifics in their natural settings is paramount to addressing more complex questions in ecology, evolution, and conservation. While much research on ants focuses on aggressive food competition between large and foraging trail-using societies, we lack a thorough understanding of inter-colony competition in socially less derived, solitarily foraging species. To fill this gap, we explored the activity of ten neighbouring colonies of the giant ant Dinoponera quadriceps, monitoring 2513 foraging trips of hundreds of workers and all its inter-individual interactions. We found that, on encountering, workers from different colonies rarely engaged in aggressive fights but instead avoided each other or performed ritualised agonistic bouts. We discovered that during foraging trips, a few workers within each colony repeatedly rubbed their gaster on the substrate, a behaviour not observed in the field before. We propose that workers use this behaviour to mark the foraging area and mark more frequently in its periphery. Only 25% of the individuals specialised in this behaviour, and we hypothesise that the specialisation results from the history of interactions and experience of individual foragers. Our study suggests that workers of contiguous D. quadriceps colonies engage in low-risk conflict, mainly displaying ritualised behaviours. As these small societies mainly rely on tiny, unpredictably scattered, albeit abundant in the environment, arthropod prey, and not on persistent food sources, they do not aggressively defend exclusive foraging territories. On the other hand, colonies rely on large overlapping foraging areas to sustain their survival and growth, most often tolerating foragers from nearby colonies. We discuss whether this type of competitive interaction is expected in all solitary foraging species.

Abstract
INTRODUCTION In Portugal, lung cancer (LC) is the first cause of cancer-related death and of death and disability combined. This study aims to analyze the overall survival (OS) and relative survival (RS) of patients diagnosed with LC in 2009-2011 by socio-demographic and tumor characteristics, and analyze sex-specific patterns. METHODS We estimated 5-year OS using the Kaplan-Meier method and 5-year net survival through the RS framework. Cox regression modeling was used to determine the hazard ratio (HR) of death associated with each independent variable. FINDINGS For the 11,523 cases analyzed, median 5-year OS was 264 days (95% confidence interval [CI]: 254.8-273.2), the cumulative OS was 13.6% and RS was 15.1%. Males had a lower median survival (237 days; 95% CI: 228.2-245.7) compared to females (416 days; 95% CI: 384.4-447.6) (p < 0.0001) and lower 5-year RS proportions (12.1% vs. 24.9%). RS progressively decreased with age (41.7% for age-group <40 to 7.2% for ≥80) and stage (66.6% for stage I to 2.4% for stage IV). As predictors of decreased survival, we identified male gender, increasing age >50, histologic types (squamous cell carcinoma, non-small cell lung cancer not otherwise specified, other unspecified and small cell lung cancer), and increasing stage. Compared to women, the risk of death in men was 37.7% higher (HR = 1.386; 95% CI: 1.295-1.484). CONCLUSIONS The differences between OS and RS were small, reflecting the high lethality of LC. Male gender and older age are factors related to poor prognosis. Histology also plays a role in survival prognosis and varies with gender, but the factor related to the worst survival is stage. Although the study reflects data from a decade ago, and major changes occurred in diagnosis, staging and treatment, particularly for advanced disease, as LC mortality is strongly correlated with late stage diagnosis, all efforts should be made to secure early diagnosis and improve survival prospects.

Abstract
The atmospheric oxidation of biogenic volatile organic compounds (BVOC) by OH radicals over tropical rainforests impacts local particle production and the lifetime of globally distributed chemically and radiatively active gases. For the pristine Amazon rainforest during the dry season, we empirically determined the diurnal OH radical variability at the forest-atmosphere interface region between 80 and 325 m from 07:00 to 15:00 LT using BVOC measurements. A dynamic time warping approach was applied showing that median averaged mixing times between 80 to 325 m decrease from 105 to 15 min over this time period. The inferred OH concentrations show evidence for an early morning OH peak (07:00-08:00 LT) and an OH maximum (14:00 LT) reaching 2.2 (0.2, 3.8) × 106 molecules cm-3 controlled by the coupling between BVOC emission fluxes, nocturnal NOx accumulation, convective turbulence, air chemistry and photolysis rates. The results were evaluated with a turbulence resolving transport (DALES), a regional scale (WRF-Chem) and a global (EMAC) atmospheric chemistry model.

Abstract
INTRODUCTION Moyamoya disease is a progressive steno-occlusive disease of the major intracranial arteries. Affected individuals are at risk for intracranial hemorrhagic or ischemic stroke, cognitive impairment, and developmental delays. Several susceptibility genes have been identified. The p.R4810K variant in the RNF213 gene has been identified in 95% of patients with familial moyamoya disease. CASE REPORT We present the case of a 15-year-old adolescent girl who presented with chief complaints of dysgraphia, lack of coordination in the right hand, with two months of evolution. Cerebral magnetic resonance imaging revealed several ischemic lesions with different rates of evolution and magnetic resonance angiography showed multiple subocclusive stenoses. In the study of the sequences of the coding regions and intronic flanking regions (±8 bp) of the RNF213 gene, the variant c.12185G>A, p.(Arg4062Gln) was detected in heterozygosity in the RNF213 gene. This result indicates that the patient is heterozygous for the c.12185G>A, p.(Arg4062Gln) variant in the RNF213 gene. The detected variant has already been reported in the literature as a founder variant in the Asian population, associated with moyamoya syndrome. This variant is described in ClinVar as a variant of unknown clinical significance? Furthermore, it is not described in population databases (dbSNP, ESP, gnomAD). CONCLUSION To our knowledge, the p.(Arg406262Gln) variant has been reported in three Japanese moyamoya disease patients and one European. Therefore, our patient was the second European moyamoya disease patient with this variant identified.

Abstract
Introduction
Self-Generated Stress might be defined as stress that is created by oneself by engaging in behavior or making decisions that ultimately add strain to pre-existing personal stress. The Self-Generated Stress Scale (SGSS; Flett et al. 2020) is a seven-item self-report measure built to assess this tendency to make one’s own life more stressful.
Objectives
To analyze the psychometric properties of the Portuguese Version of the SGSS.
Methods
Participants (127 medicine and dentistry students; 78.0% female) answered an online survey including the preliminary Portuguese version of the SGSS and other validated questionnaires: Maslach Burnout Inventory – Students Survey, Depression Anxiety and Stress Scales, HEXACO-60 and Big Three Perfectionism Scale.
Results
Confirmatory Factor Analysis showed that the unidimensional model presented good fit indexes (χ2/df=1.546; RMSEA=.0666, p<.001; CFI=.982 TLI=.972, GFI=.960). The Cronbach’s alfa was .868. Pearson correlations between SGSS and the other measures were significant (p<.01) and moderate/high: Burnout, .412; Stress/Anxiety/Depression, >.550; Perfectionism, .600; Emotionality, .315; Extroversion, -.411. After controlling for the effect of Emotionality and Extroversion, SGSS explained significant additional increments of 19.9% and 14.0% of the DASS and MBI variance; controlling for Perfectionism, the increments were respectively of 27.9% and 2.0%. SGSS mean score (22.96±5.90 was not significantly different by gender.
Conclusions
As observed with the original English-language scale, the Portuguese version of SGSS showed good validity (construct and convergent-divergent) and internal consistency. As such, the SGSS might be useful in further investigation, particularly to explore the different pathways between personality traits, emotional regulation processes and psychological distress.

Abstract
Introduction
The Inventory of Academic Sources of Stress in Medical Education (IASSME) evaluates the presence and intensity of the main sources of academic stress for Portuguese Medicine students in five dimensions: Course demands/CD, Human demands/HD, Lifestyle/LS, Academic competition/AC, and Academic adjustment/AA. Objectives To further validate the ISSME using Confirmatory Factor Analysis and to analyze[ATP1] the psychometric properties of a new version including additional sources of stress. Methods Participants were 666 Portuguese medicine (82.6%) and dentistry (17.4%) students (81.8% girls); they answered an online survey including the ISSME and other validated questionnaires: Maslach Burnout Inventory – Students Survey (MBI-SS) and Depression Anxiety and Stress Scales (DASS). Results Confirmatory Factor Analysis showed that the second order model composed of five factors (the original structure by Loureiro et al. 2008), but excluding item 11 (loading=.371), presented good fit indexes (χ2/df=3.274; RMSEA=.0581, p<.001; CFI=.917; TLI=.904, GFI=.919). The Cronbach’s alfas were α=.897 for the total and from α=.669 (F2-HD) to α=.859 (F1-CD) for the dimensions. The expanded version, including two additional items related to lack of interest in medicine/dentistry (F6, α=.543) and two additional COVID-19 stress-related-items (F7, α=.744) also showed acceptable fit indexes (χ2/df=3.513; RMSEA=.061, p<.001; CFI=.88.; TLI=.866, GFI=.892). This new version’s α was of .896. Pearson correlations between ISSME and the other measures were significant (p<.01) and high: >.55 with DASS and >.50 with MBI-SS. Girls presented significantly higher ISSME scores. F6 score was significantly higher in dentistry students. Conclusions
This further validation study underlines that IASSME presents good validity (construct and convergent) and reliability. Disclosure No significant relationships.

Abstract
Introduction The COVID-19 pandemic has completely changed the experience of higher education with potentially negative consequences for students’ wellbeing. Objectives To compare medicine/dentistry students’ depression/anxiety/stress levels before versus during the pandemic and to analyse the role of COVID-19-related stressors in their psychological distress. Methods Students from the Faculty of Medicine University of Coimbra answered socio-demographic and personality questionnaires and the Depression, Anxiety and Stress Scale/DASS before (academic years 2016-2017-2018-2019 - SAMPLE1; n=1000) and during (September-December 2020 and January-March 2021 - SAMPLE2; n=650) the COVID-19 pandemic. Mean age (21.12±3.75), personality traits scores, and gender proportions (»75% girls) did not significantly differ between samples. SAMPLE2 also filled in the Fear of COVID-19 Scale and a new version of the Inventory of Sources of Stress During Medical Education/ISSDME, containing a COVID-19 -related dimension (restrictions on training and on socializing with friends/colleagues). Results SAMPLE2 presented significantly higher mean scores of depression (3.89±3.55vs.3.33±3.34), anxiety (3.27±4.08vs.2.86±3.29), stress (7.07±5.72vs.6.18±4.59) and total DASS (12.28±10.55vs.13.65±11.13) than SAMPLE1 (all p<.05). Fear of COVID-19 was a significant predictor of DASS score (adjusted R2=2.9%, p<.001). COVID-19-related stressors continued explaining significant increments of DASS variance after controlling for each of the ISSDME dimensions: Course demands (R2 Change=1.8%), Human demands (2.5%), Lifestyle (2.3%), Academic competition (5.5%), and Academic adjustment (5.2%) (all p<.001). Conclusions This study adds to the evidence of the negative impact of COVID-19 on students and emphasizes its pernicious role on medical students’ psychological distress, which is already higher due to the individual and academic stressors to which they are more exposed.

Abstract
Introduction The COVID-19 crisis has generated an increasing stress throughout the population. Objectives To develop and validate the Adherence Scale to the Recommendations for Mental Health during the COVID-19 pandemic from the Portuguese General Directorate of Health (GDH) (ASR-MH-COVID19). Methods The items content was based on the GDH guides for the prevention of mental health and psychosocial well-being of the general population during the COVID-19 outbreak. After content and facial validity analysis, the preliminary version of the ASR-MH-COVID19 (8 items to be answered on a Likert scale) was completed by 413 individuals (69.2% female; mean age=31.02±14,272), in September-December 2020 (Sample1) and then by 967 (70.9% female; mean age=34.02±14,272), in February-May 2021 (Sample2). Sample1 was randomly divided in two sub-samples. Sample1A was used for exploratory factor analysis/EFA and Sample1B for confirmatory factor analysis/CFA; CFA was then replicated with Sample2. The online surveys also included the Adherence Scale to the Recommendations of Portuguese GDH to minimize the impact of COVID-19 (ASR-COVID-19; Pereira et al. 2020). Results CFAs were informed by EFA and showed that the unidimensional model presented acceptable-good fit indexes (Sample1B: χ2/df=2.747; RMSEA=.0980, p<.001; CFI=.973; TLI=.918, GFI=.972; Sample2: χ2/df=3.327; RMSEA=.0490, p<.001; CFI=.993; TLI=.983, GFI=.990). Cronbach’s alfas were α<.850. Pearson correlations between ASR-MH-COVID19 and ASR-COVID19 were significant (p<.01) and moderate-high for the total (r=.753) and dimensional scores (Distance and respiratory hygiene, r=.739; House and personal hygiene, r=.584; Use of remote services and isolation r=.425).

Abstract
Introduction ADHD is a risk factor for impulsive/compulsive eating problems (EP). In, bulimia nervosa and compulsive eating disorder, EP are frequently preceded by negative affect and experienced as loss of control. Clarifying the underlying causes (eg., ADHD symptoms and/or psychological distress) of EP in ADHD would allow the development of targeted interventions. Objectives To a) compare levels of EP between ADHD patients and a community sample, and b) test if ADHD symptoms and psychological distress predict EP, in ADHD patients. Methods Adults with ADHD (n=32; age=23.78+/-6.12; 69% males) from the Neurodevelopmental Outpatient Unit of Coimbra and healthy participants (n=30; age=36.90+/-13.23; 57% males) answered an online survey including the Portuguese versions of the Adult ADHD Self-Report Scale Symptom Checklist, the Parkinson’s Disease Impulsive-Compulsive Disorders Questionnaire-Current Short and the Depression, Anxiety and Stress Scale. Results The ADHD group reported experiencing more EP than healthy individuals (18/32 vs. 4/30; χ2=12.458, p<.001). ADHD patients with EP suffered from severer ADHD inattentive, hyperactive, and global symptoms and higher levels of psychological distress (p<.001 to p=.027). Logistic regression model testing if ADHD and psychological distress symptoms predicted EP, in ADHD, explained 38.8% of the variance and showed that the only significant predictor was ADHD symptoms (B=.121, SE=.051, p=.017). Conclusions Our results indicate that EP are associated with severer ADHD clinical pictures. EP arose secondarily to ADHD symptoms, instead of serving as means to alleviate psychological distress. Clinicians should be mindful that, in ADHD patients, EP follow specific motivations, i.e., impulsivity and inattention, and may respond to combined cognitive-behavioural/executive training strategy.

Abstract
Introduction The Short Form of the Self-Compassion Scale (SCS-SF; Raes et al. 2011) is composed of 12 items that evaluate the same six dimensions (Self-Kindness/SK, Self-Judgement/SJ, Common Humanity/CH, Isolation, Mindfulness/M, Over-Identification/OI) as the long scale (26 items). The Portuguese version of the SCS-SF (Castilho et al. 2015) was validated in a vast sample from clinical and general populations, the latter being composed of students, other than from medicine courses. Objectives To analyze the psychometric properties of the Portuguese version of the SCS-SF in a sample of Medicine/Dentistry students. Methods Participants were 666 Portuguese medicine (82.6%) and dentistry (17.4%) students (81.8% girls); they answered an online survey including the SCS and other validated questionnaires from the OECD Study on Social and Emotional Skills/SSES: Stress resistance, Emotional control, Optimism and Persistence. Results Confirmatory Factor Analysis showed that the model composed of six factors, two second order factors (positive and negative) and one third order factor (total) presented good fit indexes (χ2/df=3.013; RMSEA=.0066, p<.001; CFI=.970; TLI=.948, GFI=.947). The Cronbach’s alfas were .892, .869 and .877 respectively for the total, self-compassion and self-criticism dimension. Pearson correlations of the SCS-SF total score, self-compassion and self-criticism dimensional scores were moderate to high with the SSES measures, from .272/-.236/.247 with Persistence to .709/-.634/.615 with Optimism. Conclusions Although reduced to less than half than the original SCS, the SCS–SF is a valid and useful alternative to measure general self-compassion and their positive and negative components in an ongoing longitudinal research with medicine/dentistry students.

Abstract
Introduction Public health authorities around the world have been disseminating messages to support mental health and psychosocial well-being during the COVID-19 pandemic. Based on the Portuguese guidelines, we have developed the Adherence Scale to the Recommendations for Mental Health during the COVID-19 Pandemic (ASR-MH-COVID19) to better understand this health behaviour. Objectives To analyse the relationship between sociodemographics, personality traits, Adherence (to the Recommendations for Mental Health during the COVID-19 Pandemic) and psychological distress. Methods 413 individuals (69.2% female; mean age=31.02±14,272) completed an on-line survey, in September-December 2020, including sociodemographic questions, ASR-MH-COVID19, NEO-FFI-20 and Depression Anxiety Stress Scale (DASS-21) and Health Perception Scale. Results Adherence scores did not significantly differ by gender, age and years of education. Women presented higher DASS and Neuroticism scores (p<.01). Adherence were negatively correlated with Neuroticism (r=-.247) and with Depression/Anxiety/Stress (all r».-200), positively with Openness to Experience (r=.174), Conscientiousness (r=.194) and Perceived Health (Physical, r=.173 and Psychological, r=.215) (all p<.01). Mediation analysis (Hays’ Macro Process - Model 4) revealed that Adherence is a partial mediator between Openness and DASS and Conscientiousness and DASS; when considering Neuroticism, only the direct effect was significant. The effect of Perceived Health (both Physical and Psychological) on DASS was also mediated by Adherence. Conclusions The Health Behaviour Model proposes a pathway linking personality and health that applies to these results about adherence and psychological distress during the COVID-19 pandemic. Personality and perceived health (also a trait) influence both adherence to mental health behaviours and psychological distress. Understanding personality is vital for health care providers.

Abstract
Introduction
The Inventory of Academic Sources of Stress in Medical Education (IASSME) evaluates the presence and intensity of the main sources of academic stress for Portuguese Medicine students in five dimensions: Course demands/CD, Human demands/HD, Lifestyle/LS, Academic competition/AC, and Academic adjustment/AA.
Objectives
To further validate the ISSME using Confirmatory Factor Analysis and to analyze the psychometric properties of a new version including additional sources of stress.
Methods
Participants were 666 Portuguese medicine (82.6%) and dentistry (17.4%) students (81.8% girls); they answered an online survey including the ISSME and other validated questionnaires: Maslach Burnout Inventory – Students Survey (MBI-SS) and Depression Anxiety and Stress Scales (DASS).
Results
Confirmatory Factor Analysis showed that the second order model composed of five factors (the original structure by Loureiro et al. 2008), but excluding item 11 (loading=.371), presented good fit indexes (χ2/df=3.274; RMSEA=.0581, p<.001; CFI=.917; TLI=.904, GFI=.919). The Cronbach’s alfas were α=.897 for the total and from α=.669 (F2-HD) to α=.859 (F1-CD) for the dimensions. The expanded version, including two additional items related to lack of interest in medicine/dentistry (F6, α=.543) and two additional COVID-19 stress-related-items (F7, α=.744) also showed acceptable fit indexes (χ2/df=3.513; RMSEA=.061, p<.001; CFI=.88.; TLI=.866, GFI=.892). This new version’s α was of .896. Pearson correlations between ISSME and the other measures were significant (p<.01) and high: >.55 with DASS and >.50 with MBI-SS. Girls presented significantly higher ISSME scores. F6 score was significantly higher in dentistry students.
Conclusions
This further validation study underlines that IASSME presents good validity (construct and convergent) and reliability.

Abstract
Introduction
Perceived vulnerability to disease/PVD may influence psychological reactions to COVID-19 pandemic.
Objectives
To analyse the role of PVD in psychological distress/PD during the COVID-19 pandemic, testing whether it is mediated by perceived risk of COVID-19, fear of COVID-19 and repetitive negative thinking/RNT.
Methods
Participants (N=413 adults; 69.2% women) were recruited from September until December 2020, via social networks. They completed the following self-report validated questionnaires: Perceived Vulnerability to Disease Questionnaire/PVDQ; Perceived Risk of COVID-19 Scale, Fear of COVID-19 Scale; Perseverative Thinking Questionnaire and Depression Anxiety and Stress Scale. As women had significantly higher levels of PVD, COVID-19 perceived risk and fear, RNT, and psychological distress/PD, gender was controlled in mediation analysis (using PROCESS macro for SPSS; Hayes 2018).
Results
All the variables significantly (p<.01), moderately (r>.20) and positively correlated. The serial mediation model 6 with the three sequential mediators resulted in significant total effect (c=.326, se=.0791, p<.001, CI:.1702-.4814), non-significant direct effect (c’=.111, se=.065, p=.087, CI:-.0162 to .2380), significant total indirect effect (.2149, se=.065, CI:.1079-.3278); most indirect effects were significant, including the indirect 7 (.0144, se=.0077, CI=.0017-.0320), that goes through all mediators (PVD->COVID19 perceived risk->COVID19 fear->RNT->PD), meaning full mediation.
Conclusions
The effect of PVD on psychological distress operates by increasing the perception of risk and the fear of COVID-19, which intensify related worries and ruminations in times of pandemic. People with high perceived threat, aversion and discomfort in situations associated with increased risk of infection should be helped to decrease dysfunctional cognitive contents and processes in times of pandemic.

Abstract
Introduction
During a public health crisis, preventive measures are essential. However, to make them effective, all citizens must be engaged.
Objectives
To analyse the differential role of individual and contextual variables in the adherence to public health recommendations.
Methods
1376 adults (70.5% female; mean age=35.55±14.27) completed a survey between September/2020 and May/2021 with: Adherence Scale to the Recommendations during COVID-19
(ASR-COVID19; evaluates three dimensions of adherence), Fear of Covid-19 Scale (FC19S) and Toronto and Coimbra Prosocial Behaviour Questionnaire (ProBeQ; assesses empathy and altruism).
Results
Adherence did not differ between individuals with or without personal or family history of COVID-19 infection. ASR-COVID19 and all dimensions were positively correlated to ProBeQ’s altruism and empathy (from r=.32 to r=.54); FCV19S correlated positively to total adherence score and house sanitation (from r=.18 to r=.26; all p<.01). Linear regressions revealed that altruism and empathy (first model), as well as fear of Covid-19 (second model), were significant predictors of adherence; however, while the first model explained ≅28% of its variance, the second (FCV19S as independent variable) only explained ≅3%. Regression models performed in a subsample of participants with personal or family history of COVID-19 revealed that only empathy, but not altruism, was a significant predictor of adherence; in this subsample, fear was no longer a significant predictor of adherence, except for lockdown and use of teleservices.
Conclusions
Based on our results, we suggest health care providers and public health campaigns should take into consideration social solidarity and altruism, as well as previous experiences, when appealing to public’s engagement in health behaviour.

Abstract
Introduction
Evidence suggests that besides having stigmatizing misconceptions towards people with mental illness, medical students and doctors often resist seeking help for their own mental issues. This is a vulnerable group for stress and other mental health problems, due not only to professional burden but also high perfectionism and low self-compassion.
Objectives
To analyse the relationship between mental health stigma (MHS) and other variables related to personality and emotional states in a sample of medical students.
Methods
634 medicine and dentistry students (mean age = 21.6±6.9;81.4% female) answered to a survey including sociodemographic data, self-perception of psychological health/SPPH and the Portuguese validated versions of: Link’s Perceived Discrimination and Devaluation (PDD) scale to assess MHS and its two dimensions - social stigma/SocS and self-stigma/SelS; Depression Anxiety Stress Scale (DASS-21); Neff’s Self-Compassion Scale (SCS); and Big Three Perfectionism Scale (BTPS). Correlations, t-student tests and linear regressions were performed with SPSS 27.0.
Results
Stigma correlated negatively to SPPH and positively to DASS, the negative poles of SCS (self-judgement, isolation and over-identification) and BTPS second-order factors (all from p<.05 to p<.01). No gender differences in MHS were observed. Participants with higher mean levels of total and SelS had significantly higher scores in all DASS dimensions and lower SPPH; participants with higher SocS also scored higher in DASS, but didn’t reveal lower SPPH. Isolation was a significant predictor of SocS (R2=2.8%;p<.05); isolation and narcissistic perfectionism were significant predictors of SelS (R2=11%;p<.01).
Conclusions
Our results highlight the importance of including MHS as a main need in the curricula of future doctors.

Abstract
Consolation has been observed in several species, including marmoset monkeys, but it is often unclear to what extent they are empathy-based. Marmosets perform well in at least two of three components of empathy-based consolation, namely understanding others and prosociality, but it is unknown to what extent they show matching with others. We, therefore, tested whether non-aroused individuals would become aroused themselves when encountering an aroused group member (indicated by piloerection of the tail). We found a robust contagion effect: group members were more likely to show piloerection themselves after having encountered an aroused versus relaxed conspecific. Moreover, group members offered consolation behaviours (affiliative approaches) towards the aroused fellow group members rather than the latter requesting it. Importantly, this pattern was shown by both aroused and non-aroused individuals, which suggests that they did not do this to reduce their own arousal but rather to console the individual in distress. We conclude that marmosets have all three components of empathy-based consolation. These results are in line with observations in another cooperative breeder, the prairie vole.

Abstract
Erythromelalgia (EM) is a rare autosomal dominant neuropathy characterized by the combination of severe burning pain and erythematous warm extremities. Chronic pain control is most often unsuccessful and a completely effective therapy is yet to be identified. Recent studies have reported significant improvements in pain management using a combination of amitriptyline and ketamine in a topical formulation. We describe a 1-year follow-up pain control success case of a male patient with EM, proposed for topical use of a 2% Amitriptyline and 0.5% Ketamine gel.

Abstract
Social tolerance in a group reflects the balance between within-group competition and interdependence: whereas increased competition leads to a reduction in social tolerance, increased interdependence increases it. Captivity reduces both feeding competition and interdependence and can therefore affect social tolerance. In independently breeding primates, social tolerance has been shown to be higher in captivity, indicating a strong effect of food abundance. It is not known, however, how social tolerance in cooperative breeders, with their much higher interdependence, responds to captivity. Here, we therefore compared social tolerance between free-ranging and captive groups in the cooperatively breeding common marmoset and found higher social tolerance (measured as proximity near food, co-feeding, and food sharing) in the wild. Most likely, social tolerance in the wild is higher because interdependence is particularly high in the wild, especially because infant care is more costly there than in captivity. These results indicate that the high social tolerance of these cooperative breeders in captivity is not an artefact, and that captive data may even have underestimated it. They may also imply that the cooperative breeding and foraging of our hominin ancestors, which relied on strong interdependence at multiple levels, was associated with high social tolerance.

Abstract
Abstract
Background
In Portugal, there are no published data on the health-related consequences of prescription drug misuse, which is therefore a public health issue of unknown dimension in our country. Poison control centres and other pharmacoepidemiological sources can be part of a surveillance system for monitoring medicine's use and misuse.
Methods
Retrospective observational study of intentional exposures to opioid analgesics, antiepileptics, antidepressants, anxiolytics, hypnotics and sedatives reported to the Portuguese Poison Information Centre (CIAV) between 2014 and 2018. Variables studied were demographic characteristics of individuals, geographic distribution of calls, co-exposure to alcohol or illicit drugs, call origin, case evaluation and guidance.
Results
CIAV received 24624 calls reporting 34203 intentional exposures to any medicine, 31169 (91.1%) of which involving one of the studied psychoactive medicines and 20906 exposures having emergency room advice or effective hospitalisation. The most frequently involved medicines were benzodiazepines (62.0%) - alprazolam (15.4%) and diazepam (12.0%) - with trazodone ranking fifth (6.0%). Combination with non-medicinal products was seen in 2169 calls (9.4%), 2052 (94.6%) of which with alcohol.
Conclusions
There is female predominance in the poisonings reported involving any of the medicines studied. Benzodiazepines and antidepressants are the top classes reported. The rate of intentional exposures to psychoactive medicines is higher in Coimbra district, whose significant university student population requires further analysis of data. To adjust for the variability in the level of medicines' use in the population, work is undergoing to include rates of intentional poisonings in patients prescribed the studied medicines. To better characterise the potential consequences of misuse of psychoactive prescription drugs in Portugal, additional data on deaths involving these medicines will also be included in the project.
Key messages
First published Portuguese data on prescription drug poisoning reported to CIAV. First Portuguese project to analyse prescription drug poisoning, forensic and hospitalisation data.

Abstract
Understanding the set of factors that promote and constrain a species' ability to exploit ecologically distinct habitats is central for addressing questions of intraspecific variability in behavior and morphology. In this study, we compared newly collected data with published data on body measurements, group size and composition, daily path length, home range, and reproductive output in wild common marmosets naturally inhabiting two contrasting environments in northeastern Brazil: the Atlantic Forest (AF), which is characterized by high biodiversity and reduced seasonality in food availability and the Caatinga (CAT), which is characterized by a severe hot and dry season lasting from 5 to 11 months, drought-resistant plant species, and reduced primary productivity. Despite marked differences in ecological conditions, CAT marmosets and AF marmosets differed minimally in daily path length, home range, reproductive output, and infant survivorship. CAT marmosets were found to live in smaller groups containing fewer adult females than AF marmosets, and also were characterized by a greater surface area to body mass ratio, a trait that may represent an adaptation to the hot and dry conditions of the Caatinga. We propose that in conjunction with body mass reduction, minor adjustments in behavior, the exploitation of cacti as a source of water and nutrients, and access to exudates as a dependable year-round food resource, common marmosets successfully used the same adaptive pattern to maintain high reproductive output and infant survivorship in exploiting these two ecologically distinct environments.

Abstract
The present study reports the production of upconverter nanostructures composed by a yttrium oxide host matrix co-doped with ytterbium and europium, i.e., Y2O3:Yb3+/Eu3+. These nanostructures were formed through the dissociation of yttrium, ytterbium and europium oxides using acetic, hydrochloric and nitric acids, followed by a fast hydrothermal method assisted by microwave irradiation and subsequent calcination process. Structural characterization has been carried out by X-ray diffraction (XRD), scanning transmission electron microscopy (STEM) and scanning electron microscopy (SEM) both coupled with energy dispersive X-ray spectroscopy (EDS). The acid used for dissociation of the primary oxides played a crucial role on the morphology of the nanostructures. The acetic-based nanostructures resulted in nanosheets in the micrometer range, with thickness of around 50 nm, while hydrochloric and nitric resulted in sphere-shaped nanostructures. The produced nanostructures revealed a homogeneous distribution of the doping elements. The thermal behaviour of the materials has been investigated with in situ X-Ray diffraction and differential scanning calorimetry (DSC) experiments. Moreover, the optical band gaps of all materials were determined from diffuse reflectance spectroscopy, and their photoluminescence behaviour has been accessed showing significant differences depending on the acid used, which can directly influence their upconversion performance.

Abstract
IntroductionThe cognitive emotions regulation questionnaire (CERQ) is a 36-item questionnaire to measures specific cognitive emotion regulation strategies used in response to the experience of threatening or stressful life events. The Portuguese version of CERQ proved to be a reliable and valid measure to evaluate eight dimensions: Positive reappraisal and planning, positive refocusing, rumination, blaming others, putting into perspective and self-blame.ObjectiveTo confirm the dimensional structure of a Portuguese short version of the CERQ using Confirmatory Factor Analysis (CFA).MethodItems selection was based on the previous results of the exploratory factor analysis of the 36-items version. Items presenting the highest loading (≥ 70) in their respective factor were selected. A preliminary short version composed of 22 items were answered by a sample of 480 university students (81.9% females), with a mean age of 19.49 years (SD = 2.047; range = 17–30). CFA (using Mplus software) was used to test if the eight dimensions’ model suggested by prior exploratory factor analyses fitted the data.ResultsThe eight dimensions’ model has a good fit (χ2 = 424.015, P < .01; RMSEA = 0.056, 90%CI = 0.049–0.063; CFI = 0.930; TLI = 0.910; SRMR = 0.051). Although composed of fewer numbers of items, all subscales presented good reliability (Cronbach alpha< 70).ConclusionsThe CERQ-22 is a reliable and valid measure to evaluate cognitive emotion regulation strategies in young adults. Being a shorter version it is particularly useful for multivariate and prospective studies. In the near future we will test this structure in a clinical sample.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Highlights The average diet cost was 4.58€ (SD = 1.24) in 6-12 years-old children.Diet cost calculations were based on food prices information from 2011.Most children reported medium (69.1%) or high (4.6%) adherence to Mediterranean diet.Higher adherence to Mediterranean diet was associated with higher diet cost. Objective To assess how the diet cost is associated with socio-demographic factors and adherence to Mediterranean diet in children. Methods Data were obtained from a community-based survey of children selected from public elementary schools in Portugal. Of a total of 586 children attending these schools, 464 (6-12 years), were studied. Dietary intake was assessed by a 24 hour recall and the adherence to Mediterranean diet was evaluated through the KIDMED index. The cost of the diet was calculated based on the collection of food prices of a national leader supermarket, and expressed as Total Daily Cost (TDC) and Total Daily Cost-Adjusted for Energy (TDEC). Anthropometric measures were taken and socio-demographic data were gathered from a questionnaire filled by parents. Logistic regression was used to quantify the association between diet cost, socio-demographics and adherence to Mediterranean diet. Results The average TDC was 4.58€ (SD = 1.24). Most children (69.1%) reported medium adherence to Mediterranean diet, and 4.6% rated the higher score. TDC was higher for children with highest adherence to Mediterranean diet, compared to those with lowest adherence [TDC: OR = 5.70 (95% CI 1.53, 21.33), p for trend = 0.001; TDEC: OR = 2.83 (95% CI 0.89, 8.96, p for trend 0.018)]. No meaningful variation in the diet cost with age and parental education was observed. Conclusion Higher adherence to Mediterranean diet was associated with higher diet cost in children.

Abstract
Natural products, sources of new pharmacological substances, have large chemical diversity and architectural complexity. In this context, some toxins obtained from invertebrate venoms have anticonvulsant effects. Epilepsy is a neurological disorder that affects about 65 million people worldwide, and approximately 30% of cases are resistant to pharmacological treatment. Previous studies from our group show that the denatured venom of the ant Dinoponera quadriceps (Kempt) protects mice against bicuculline (BIC)-induced seizures and death. The aim of this study was to investigate the anticonvulsant activity of compounds isolated from D. quadriceps venom against seizures induced by BIC in mice. Crude venom was fractionated by high-performance liquid chromatography (HPLC) resulting in six fractions referred to as DqTx1-DqTx6. A liquid chromatography-mass spectrometry (LC/MS) analysis revealed a major 431 Da compound in fractions DqTx1 and DqTx2. Fractions DqTx3 and DqTx4 showed a compound of 2451 Da and DqTx5 revealed a 2436 Da compound. Furthermore, the DqTx6 fraction exhibited a major component with a molecular weight of 13,196 Da. Each fraction (1 mg/mL) was microinjected into the lateral ventricle of mice, and the animals were observed in an open field. We did not observe behavioral alterations when the fractions were given alone. Conversely, when the fractions were microinjected 20 min prior to the administration of BIC (21.6 nM), DqTx1, DqTx4, and DqTx6 fractions increased the latency for onset of tonic-clonic seizures. Moreover, all fractions, except DqTx5, increased latency to death. The more relevant result was obtained with the DqTx6 fraction, which protected 62.5% of the animals against tonic-clonic seizures. Furthermore, this fraction protected 100% of the animals from seizure episodes followed by death. Taken together, these findings indicate that compounds from ant venom might be a potential source of new anticonvulsants molecules.

Abstract
OBJECTIVE There is evidence that fruit consumption among school children is below the recommended levels. This study aims to examine the effects of a dietary education intervention program me, held by teachers previously trained in nutrition, on the consumption of fruit as a dessert at lunch and dinner, among children 6-12 years old. STUDY DESIGN This is a randomized trial with the schools as the unit of randomisation. METHODS A total of 464 children (239 female, 6-12years) from seven elementary schools participated in this cluster randomized controlled trial. Three schools were allocated to the intervention and four to the control group. For the intervention schools, we delivered professional development training to school teachers (12 sessions of 3 h each). The training provided information about nutrition, healthy eating, the importance of drinking water and healthy cooking activities. After each session, teachers were encouraged to develop classroom activities focused on the learned topics. Sociodemographic was assessed at baseline and anthropometric, dietary intake and physical activity assessments were performed at baseline and at the end of the intervention. Dietary intake was evaluated by a 24-h dietary recall and fruit consumption as a dessert was gathered at lunch and dinner. RESULTS Intervened children reported a significant higher intake in the consumption of fruit compared to the controlled children at lunch (P = 0.001) and at dinner (P = 0.012), after adjusting for confounders. CONCLUSIONS Our study provides further support for the success of intervention programmes aimed at improving the consumption of fruit as a dessert in children.

Abstract
IntroductionThe FMPS is a 35-item self-report questionnaire to measure perfectionism. It evaluates: concern over mistakes/CM, doubts about actions/DA, parental criticism/PC and expectations/PE, personal standards/PS and organization/O.ObjectivesTo develop a shortened version of FMPS and study its internal consistency, the construct, concurrent and divergent validity.MethodsOne hundred and ninety-two university students (78.1% females), aged 19.74 years (sd = 2.10) completed the Portuguese versions of the: FMPS, Hewitt and Flett MPS/H&FMPS, Life Orientation Test Revised/LOT-R, State-Trait Anxiety Inventory/STAI, and Profile of Mood States/POMS.ResultsCorrelations between each item and corrected FMPS total scores/corrected total subscales scores were ≥ 0.20 for the items 13, 15, 25, 31, 35 and 10, 2, 25, and 26, respectively. The internal consistency of FMPS was high (α: .857) with 32 items contributing for this consistency (exceptions: 13, 25 and 31). The principal component analysis of the 35 items with factors varimax rotation was performed. The three items with higher loading in each factor that also contributed to the FMPS reliability were selected for the FMPS shortened version (FMPS-18). The principal component analysis of the 18 items with factors varimax rotation showed that six factors explained 74.6% of FMPS-18 total variance. These factors revealed adequate internal consistency (α: O = 0.740; PC = 0.859; PE = 0.847; PS = 0.726; CM = 0.740; DA = 0.832; total = 0.768). Convergent correlations between FMPS and the matched FMPS-18 scores were 0.839 to 0.971 (all P < .01). Correlations of the FMPS-18 and FMPS with H&F-MPS, STAI, LOT-R and NA/PA scores were of similar significance and valence.ConclusionFMPS-18 is a brief, reliable and valid instrument to measure perfectionism.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Epilepsy affects at least 50 million people worldwide, and the available treatment is associated with various side effects. Approximately 20-30% of the patients develop seizures that persist despite careful monitored treatment with antiepileptic drugs. Thus, there is a clear need for the development of new antiepileptic drugs, and the venoms can be an excellent source of probes. In this context, while there are studies on venoms from snakes, scorpions, and spiders, little is known regarding venom from ants. The aim of this study was to investigate the potential pro- and anticonvulsant effects of the venom from the ant Dinoponera quadriceps (Kempf) in Swiss mice. After the injection of the crude venom (DqTx-5, 50, and 500 mg/mL) in the lateral ventricle of mice, we observed a reduction of exploration and grooming behaviors, as well as an increase in immobility duration. In addition, the crude venom induced procursive behavior and tonic-clonic seizures at the highest concentration. Conversely, the preadministration of the denatured venom (AbDq) at the concentration of 2 mg/mL protected the animals against tonic-clonic seizures (66.7%) and death (100%) induced by administration of bicuculline. Taken together, the findings demonstrate that D. quadriceps venom might be potential source of new pro- and anticonvulsants molecules.
