Abstract
BackgroundDepression, and its improvement with disease modifying anti-rheumatic drugs (DMARDs) is understudied in psoriatic arthritis (PsA).ObjectivesTo determine the effectiveness of DMARDs on depression in PsA patients.MethodsPatients enrolled from January 2000 to May 2020 in a large PsA cohort were included. Depression was defined as medical outcomes study short form-36 (SF-36) mental component summary score (MCS) ≤ 40 or mental health (MH) subscale score ≤ 56. Primary outcome was resolution of depression within 1 year of DMARDs, defined by two definitions: 1) MCS > 40 and/or MH subscale score of > 56; 2) Increase in MCS by 2.5 and MH subscale score by 5, the minimal clinically important difference (MCID). Baseline medications [non-steroidal anti-inflammatory drugs (NSAIDs) and/or conventional or targeted (c/t) DMARDs] were recorded for all patients and stratified into 3 mutually exclusive ordinal categories: I-No treatment/NSAIDs; II-cDMARDs±NSAIDs without tDMARDs; III-tDMARDs±cDMARDs/NSAIDs. Univariable and multivariable logistic regression models were created to determine the association between medications and resolution of depression, after controlling for age, sex, disease duration and baseline MCS/MH subscale score.ResultsBased on the MCS and MH subscale score definitions, 608 (48%) and 655 (52%) of the 1270 patients, respectively were depressed at baseline. 374 (50.8% males) and 399 (52.4% males) patients were followed up in the groups defined by MCS and MH subscales, respectively for 1 year. Patients in both groups had comparable body mass indices, baseline psoriasis area and severity index and active joint count. Mean MCS and MH subscale scores (standard deviation) were 33.2 (5.2) and 46.0 (10.2). A mean of 11.9 and 11.7 months was noted for resolution of depression in the MCS based analysis and MH subscale-based analysis groups, respectively. More patients achieved resolution of depression based on definition 2 (MCS, 64.7%; MH, 62.2%) as compared to definition 1 (MCS, 54.5%; MH, 53.9). The proportion of patients on each category of medications in both models is shown in the Figure 1. Table 1 depicts the univariate and multivariable regression results by both the definitions of primary outcome in the MH subscales model. The global p-value for medication categories showed a trend towards significance in both models using definition 2. There was a trend towards higher likelihood of response when comparing patients in treatment category III vs category I. A significant response was noted when comparing patients in category III with category II as reference (OR 1.71; 95% CI 1.05-2.76; p 0.03). No significant effect of treatment category on depression was noted using definition 1.Table 1.Association between treatment and resolution of depression in the MH Subscale model (n = 399)VariableResolution by MCIDResolution by MH subscale reductionUnivariable modelMultivariable modelUnivariate modelMultivariate modelOR (95% CI)p valueOR (95% CI)p valueOR (95% CI)p valueOR (95% CI)p valueMale vs. Female0.81 (0.54–1.22)0.310.83 (0.5–1.26)0.391.02 (0.68–1.51)0.940.94 (0.63 –1.42)0.79Baseline age1.01 (1.00 –1.03)0.091.01 (1.00 –1.03)0.161.02 (1.00–1.03)0.051.01 (0.99 –1.03)0.30Baseline PsA duration1.02 (1.00 –1.04)0.121.01 (0.99 –1.03)0.371.02 (1.00– 1.04)0.071.01 (0.99 –1.03)0.22Baseline MH subscale score0.98 (0.96 –1.00)0.030.98 (0.95 –1.00)0.021.04 (1.02– 1.06)<0.00011.04 (1.02 –1.06)<0.0001Medication category0.07*0.09*0.20*0.20* IReference II0.81 (0.48 –1.36)0.420.83 (0.48 –1.41)0.481.09 (0.65– 1.82)0.751.12 (0.66 –1.91)0.67 III1.40 (0.84 –2.36)0.201.41 (0.83 –2.38)0.201.51 (0.92– 2.49)0.101.55 (0.92 –2.59)0.10*global p valueFigure 1.Patients in each drug category.ConclusionIn an observational setting, resolution of depression occurs in majority of patients with PsA within 1 year.

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 Portuguese version of the Fear of COVID-19 Scale (FCV-19S; Cabaços et al. 2021), composed of seven items, presented good validity and reliability to be used in general population. To be used within perinatal context, specifically in the postpartum period, we have added an item related to the baby (item 8 – “I’m afraid my baby will be infected with coronavirus-19”). Objectives To analyze the psychometric properties of Portuguese adapted version of the Fear of COVID-19 Scale for the postpartum period (FCV-19SP), namely construct validity, internal consistency, and convergent validity. Methods 207 women (mean age= 33.51 ± 5.23 years) recruited in the postpartum period (9,06 ± 8,52 months after delivery) fill in a set of self-reported validated questionnaires: Perinatal Depression Screening Scale (PDSS), Perinatal Anxiety Screening Scale (PASS) and Coronavirus-19 Fear Scale for the postpartum period (FCV-19SP). Results CFA revealed that the unifactorial model composed of eight items presented good fit indexes (X2/df=1.508; CFI=.991; GFI=.974; TLI=.983; p[RMSEA≤.01] = .049), better than those of the seven items version (X2/df=3.963; CFI=.957; GFI=.909; TLI=.905; p[RMSEA≤.01] =.219). Cronbach alpha for the FCV-19SPP was α=.880. The total score significantly (p<.01) and moderately correlated with PDSS (r=.262) and PASS (r=.371). Conclusions The FCV-19SP is a valid and reliable questionnaire to assess fear of COVID-19 in women in the postpartum period. Disclosure No significant relationships.

Abstract
Introduction The Portuguese shortest version of the Perinatal Depression Screening Scale/PDSS-7 proved to be valid and reliable, in Portugal and Brazil, but it is essential to analyze its operational characteristics before using it for screening purposes. Objectives To determine PDSS-7 cut-off points and associated conditional probabilities to screen for major depression, according to the DSM-5. Methods he pregnancy sample was composed of 259 women in the second trimester (Mean gestation weeks=17.83±4.750). The postpartum sample consisted of 241 women assessed between the 2nd-6thmonths postpartum(M=17.99±4.689 weeks postpartum). All women completed the PDSS-7 and were interviewed with the Diagnostic Interview for Psychological Distress(Pereira et al., 2017), a semi-structured clinical interview to assess the most prevalent psychiatric disorders in the perinatal period according to the DSM-5 criteria. MedCalc was used to perform ROC analysis. Results During pregnancy, the major depression prevalence was of 4.6%(n=12). The cut-off point that maximizes the Youden Index(J=.98, 95%CI: .97-.99; AUC=.99; se=.004; p<.001) was of 18(95%CI:17-19), which resulted in a sensitivity of 100%(71.5%-100%), a specificity of 97.98%(95.3%-99.3%), a positive predictive value/+PP of 68.8%(48.0%-84.0%) and a negative predictive value/-PP of 100%. In the postpartum, the major depression prevalence was of 10.4%(n=25). The cut-off point(J=.79, 95%CI: .63-.82; AUC=.89; se=.036; p<.001) was of 14(95%CI: 12-16), with a sensitivity of 85.0%(69.3%-93.2%), a specificity of 85.0%(69.3%-93.2%), a +PP of 56.5%(46.1%-67.3%) and a -PP of 97.5%(94.6%-98.8%). Conclusions The Portuguese version of PDSS-7 presents good combinations of sensitivity and specificity, being accurate and usable to screen for depression during pregnancy and in the postpartum both in research and primary health care.

Abstract
Introduction
Almost 5 million people worldwide have lost their lives due to SARS-CoV-2 (source: WHO coronavirus (COVID-19) dashboard, data of 1.10.2021; https://covid19.who.int/) and therefore, globally, there is an increase of people in grief due to the death of a significant other.
Objectives
To study psychological correlates of grief during the COVID-19 pandemic.
Methods
591 university students, with a mean age of 23.84±7.95 years (range 18-65 years; 76.8% women; 91.2% Portuguese) completed an online questionnaire during the second COVID-19 confinement (from 15.02 to 13.03.2021), with sociodemographic questions, the Pandemic Stress Index, the Mental Health Inventory, Insomnia Scale, questions on physical/ psychological health, and social isolation.
Results
Students bereaving the death of a significant other (n=93, 15.7%; n=25, 26.9% reported cause was SARS-CoV-2; time since death: < 3 months to 1-year), compared to those who did not (n= 498; 84.3%), described poorer psychological health, higher psychological distress (depression, anxiety, lack of control) and sleep difficulties, higher levels of stress (higher impact of COVID pandemic in daily life, and higher behavior changes in response to COVID-19) and more social isolation.
Conclusions
COVID-19 pandemic-related stress is a source of additional stress for bereaved students. Grief is also associated with social isolation, poor mental health (depression, anxiety, lack of control) and sleep difficulties. Screening efforts, guidance, and counseling from professionals of mental health care, primary health care, and universities health care services during and after the COVID-19 pandemic could be extremely beneficial for bereaved students, particularly for those at higher risk of developing prolonged grief disorder.

Abstract
Introduction We have recently validated the Portuguese shortest version of the Perinatal Depression Screening Scale-PDSS-7 (items selected from the PDSS-21; each one representing a dimension evaluated by the PDSS-35), for the assessment of depression severity in pregnancy, both in Portugal and Brazil. Objectives To analyze the validity and reliability of the PDSS-7 Portuguese version to evaluate postpartum women both from Portugal and Brazil. Methods The Portuguese sample was composed of 304 women between the 2nd-6th postpartum months (Mean=20.09±7.21 weeks postpartum). These participants were not the same who participated in the psychometric study that led to the selection of the seven items. The Brazilian sample was composed of 121 women (Mean=10.51±4.53 weeks postpartum). All the participants completed the European/Brazilian Portuguese versions of PDSS-21, which was composed of the same items and included the seven items of PDSS-7. Participants also filled in the validated versions of Perinatal Anxiety Screening Scale and Profile of Mood States. Results Confirmatory Factor Analysis revealed that the unidimensional model of PDSS-7 presented acceptable/good fit indexes in both samples (Portuguese/Brazilian: χ2/d.f.=2.6598/1.7897; RMSEA=.0740/.0807, CFI=.8289/.7934, TLI=.7901/.8434, GFI=.9298/.9496; p<.001). The PDSS-7 Cronbach’s alphas were of .841/.856 and all the items contributed to the internal consistency. Pearson correlations with postpartum anxiety (.646/.763) and negative affect (.666/.676) were significantly (p<.01) high. PDSS-7 mean scores were higher in the Brazilian sample (16.06±7.39 versus 11.37±4.37, p<.01). Conclusions PDSS-7 presented validity (construct and convergent), reliability and utility in clinical and research settings, including in transcultural studies, in Portugal and Brazil, namely in the postpartum.

Abstract
BackgroundThe impact of immunosuppressants on COVID-19 vaccination response and durability in patients with immune-mediated inflammatory diseases (IMID) is yet to be fully characterized. Humoral response may be attenuated in these patients especially those on B cell depleting therapy and higher doses of corticosteroids, but data regarding other immunosuppressants are scarce.ObjectivesWe aimed to investigate antibody and T cell responses and durability to SARS-CoV-2 mRNA vaccines (BNT162b and/or mRNA 1273) in IMID patients on immunomodulatory maintenance therapy other than B-cell depleting therapy and corticosteroids.MethodsThis prospective observational cohort study examined the immunogenicity of SARS-CoV-2 mRNA vaccines in adult patients with IMIDs (psoriatic arthritis, psoriasis, inflammatory bowel disease and rheumatoid arthritis) with or without maintenance immunosuppressive therapies (anti-TNF, methotrexate/azathioprine [MTX/AZA], anti-TNF + MTX/AZA, anti IL12/23, anti-IL-17, anti-IL23) compared to healthy controls. Automated ELISA for IgGs to spike trimer, spike receptor binding domain (RBD) and the nucleocapsid (NP) and T-cell release of 9 cytokines (IFNg, IL2, IL4, IL17A, TNF) and cytotoxic molecules (sFasL, GzmA, GzmB, Perforinin) in cell culture supernatants following stimulation with spike or NP peptide arrays were conducted at 4 time points: T1=pre vaccination, T2=median 26 days after dose 1, T3=median 16 days after dose 2 and T4=median 106 days after dose 2. Neutralization assays against four SARS-CoV-2 variants (wild type, delta, beta and gamma) were conducted at T3.ResultsWe followed 150 subjects: 26 healthy controls and 124 IMID patients: 9 untreated, 44 on anti-TNF, 16 on anti-TNF with MTX/AZA, 10 on anti-IL23, 28 on anti-IL12/23, 9 on anti-IL17, 8 on MTX/AZA (Table 1). Most patients mounted antibody and T cell responses with increases from dose 1 to dose 2 (100% seroconversion at T3) and some decline by T4, with variability within groups. Antibody levels and neutralization efficacy was lower in anti-TNFgroups (anti-TNF, anti-TNF + MTX/AZA) compared to controls and waned by T4 (Figure 1). T cell responses were not consistently different between groups. Pooled data showed a higher antibody response to mRNA-1273 compared to BNT162b.Table 1.Baseline characteristics of study participantsControluntreated IMIDAnti- TNFAnti- TNF +MTX/AZAAnti-IL-23Anti -IL-12/23Anti -IL-17MTX/AZAn=26n=9n=44n=16n=10n=28n=9n=8p-valueIMID*N/A IBD9301002704 Psoriasis1318122 PA0732172 AS0830010 RA1100011Age median years [IQR]36 [26-46]33 [27-41]38 [30-51]53 [44-59]48 [45-61]34 [28-47]49 [46-61]42 [31-55]<0.001^Sex male (%)16 (62)5 (56)18 (41)8 (50)5 (50)13 (46)6 (67)4 (50)0.772~BMImedian kg/m2 [IQR]25 [23-28]26 [22-27]22 [24-26]26 [24-28]27 [24-35]22 [21-24]32 [26-34]26[25-33]0.001^Vaccine interval median days [IQR]74 [35-84]54 [31-64]60 [45-69]64 [50-72]74 [35-84]62 [49-69]65 [52-75]58 [21-97]0.372^*multiple IMIDs per patient possibleFigure 1.Antibody responses (A) Anti spike and anti RBD IgG levels at indicated time points.

Abstract
Introduction Psychogenic nonepileptic seizures (PNES) consist of paroxysmal changes in responsiveness, movements, or behaviour that superficially resemble epileptic seizures. Objectives Presentation of a clinical case of a PNES in a patient with a diagnose of secondary epilepsy, illustrating the relevance of an adequate evaluation, differential diagnosis, and intervention. Methods Description of the clinical case, with brief literature review and discussion. A search was conducted on PubMed and other databases, using the MeSH terms “nonepileptic seizure”, and “epileptic seizure”. Results We report the case of a 45-year-old female patient, brought to the emergency department because of tonic axial and limb nonsynchronous movements, closed eyes, long duration, with immediate awareness, no desaturation, tongue bite, facial flushing, dyspnoea or sphincter incontinency. She was medicated with clonazepam 1 mg and levetiracetam 1000 mg ev. TC-CE had no acute alteration. Bloodwork had no other major alteration except valproic acid below therapeutic levels (her usual medication, along with other antiepileptic drugs, antidepressant and antipsychotic). The antecedents of the patient: mild intellectual disability and an accidental traumatic brain injury in infancy, with secondary epilepsy. She was transferred to Psychiatry department. No electroencephalogram (EEG) was realized, because she had a recent one confirming PNES, and many other emergency observations with the diagnosis of PNES. Conclusions This clinical case showcases the diagnostic difficulties that clinicians face when there is an overlap in symptoms, emphasizing the need to combine patient history, witness reports, clinician observations, and ictal and interictal EEG to help distinguish these different clinical identities.

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
Reentrance, the return of a system from an ordered phase to a previously encountered less-ordered one as a controlled parameter is continuously varied, is a recurring theme found in disparate physical systems, yet its microscopic cause is often not investigated thoroughly. Here, through detailed characterization and theoretical modeling, we uncover the microscopic mechanism behind reentrance in the strongly frustrated pyrochlore antiferromagnet Er_{2}Sn_{2}O_{7}. We use single crystal heat capacity measurements to expose that Er_{2}Sn_{2}O_{7} exhibits multiple instances of reentrance in its magnetic field B vs temperature T phase diagram for magnetic fields along three cubic high symmetry directions. Through classical Monte Carlo simulations, mean field theory, and classical linear spin-wave expansions, we argue that the origins of the multiple occurrences of reentrance observed in Er_{2}Sn_{2}O_{7} are linked to soft modes. These soft modes arise from phase competition and enhance thermal fluctuations that entropically stabilize a specific ordered phase, resulting in an increased transition temperature for certain field values and thus the reentrant behavior. Our work represents a detailed examination into the mechanisms responsible for reentrance in a frustrated magnet and may serve as a template for the interpretation of reentrant phenomena in other physical systems.

Abstract
Aims Less-than-full-time (LTFT) training is increasing in availability and flexibility. Negative perceptions by consultants is a concern. This study aims to ascertain the attitudes of consultants to LTFT training and determine potential barriers to LTFT training. Methods A prospective cohort questionnaire-based study was designed with mixed qualitative and quantitative methodology. It was distributed to consultants in a tertiary paediatric hospital. The main outcome measures were likelihood of negative perceptions of LTFT NCHDs, and perceived advantages and disadvantages of LTFT training. Results 35.4% had worked LTFT, and 40.5% (n=17) of those who hadn't had considered or were currently considering it. Most respondents did not have a negative perception of LTFT NCHDs (84.6%). Work-life balance, reduction of burnout, and being fully committed were perceived advantages of LTFT training to NCHDs. Advantages to the team were energy, staffing, and productivity. Disadvantages to the NCHD were training duration, involvement in clinical activities, and negative perceptions. Disadvantages to the team were continuity, roster planning, and workload distribution. Conclusion Consultant perceptions of LTFT trainees are positive. There are common themes in the perceived impact of LTFT training that must be explored to maximise the success of this training pathway.

Abstract
Background:Systemic sclerosis (SSc) is a multisystem disease characterized by functional and structural abnormalities of small blood vessels, fibrosis of the skin and internal organs. In addition, volume reduction and shape abnormality of the hippocampus have been demonstrated in rheumatic and neurodegenerative diseases. However, the neuroanatomy of the hippocampus is complex and is not a uniform structure, consisting of subfields with distinct morphology: cornu ammonis (CA) subfields CA1–4, dentate gyrus (DG), fimbria, and adjacent subiculum and presubiculum [1].Objectives:To investigate the hippocampal subfields volumes reduction in SSc patients using MRI.Methods:In this study we included 37 SSc patients (33 women, mean age of 53.46, SD ± 12.29; range 30 - 78) and 37 healthy controls (HC) (31 women, mean age of 48.41, SD±12.20; range 29 - 80). Cognitive evaluation was performed using the Montreal Cognitive Assessment (MoCA), mood disorders were determined through Beck’s Depression (BDI) and Beck’s Anxiety Inventories (BAI). SSc patients were further assessed for clinical and laboratory SSc manifestations, disease activity (Valentini Activity Index), severity activity (Medsger Severity Index). MRI protocol consisted of: Sagittal T1-weighted images performed with a Philips 3.0T MRI scanner. MRI brain structure volumetric was done through volBrain [2]. After 48 months MRI acquisition were repeated in 26 SSc patients and 12 healthy volunteers. Statistics was performed according nature of the variable.Results:We observed a significant reduction in hippocampal subfields volumes in SSc patients when compared to controls: Total hippocampi (SSc: mean volume = 4.78 cm3; SD = 0.38; HC: mean volume = 5.01 cm3; SD = 0.38; p = 0.033). Reduction in volume of the total hippocampi was associated with Raynaud’s phenomenon (p = 0.006). A longitudinal study showed a reduction in volume of the hippocampus subfields volumes when compared to patient’s baseline: Total hippocampi (mean initial volume = 4.78 cm3; mean follow-up volume = 4.50 cm3, p = 0.027); Total CA1 (mean initial volume = 1.59 cm3; mean follow-up volume = 1.58 cm3, p < 0.0001); Reduction in volume of the total hippocampi was associated with presence of current use of prednisone (p = 0.008). Reduction in left CA1 left associated with current use of prednisone (p = 0.014). Reduction in total subiculum was associated with presence of calcinosis (p = 0.023). No significant changes were observed in hippocampal subfields volumes in controls over the follow-up period.Conclusion:This study provides evidence of hippocampus subfields volumes reductions in SSc patients when compared to controls and was associated with Raynaud’s phenomenon, current use of losartan and correlated with BAI scores. Also, a longitudinal study showed a reduction in volume of the hippocampus subfields volumes when compared to patient’s baseline associated with calcinosis and current use of prednisone.References:[1]Eichenbaum, Howard. “A cortical–hippocampal system for declarative memory.” Nature Reviews Neuroscience 1.1 (2000): 41-50.[2]Manjon JV, Coupe P (2016) volBrain: an online MRI brain volumetry system.

Abstract
Several plant pathogenic Parastagonospora species have been identified infecting wheat and other cereals over the past 50 years. As new lineages were discovered, naming conventions grew unwieldy and the relationships with previously recognized species remained unclear. We used genome sequencing to clarify relationships among these species and provided new names for most of these species. Six of the nine described Parastagonospora species were recovered from wheat, with five of these species coming from Iran. Genome sequences revealed that three strains thought to be hybrids between P. nodorum and P. pseudonodorum were not actually hybrids, but rather represented rare gene introgressions between those species. Our data are consistent with the hypothesis that P. nodorum originated as a pathogen of wild grasses in the Fertile Crescent, then emerged as a wheat pathogen via host-tracking during the domestication of wheat in the same region. The discovery of a diverse array of Parastagonospora species infecting wheat in Iran suggests that new wheat pathogens could emerge from this region in the future.

Abstract
IntroductionDespite being essential for the service quality improvement, empirical research on the characteristics of people hospitalized in forensic psychiatry units and the psychopharmacological treatment instituted in this care context is scarce in Portugal.ObjectivesTo describe the sociodemographic, clinical and criminological characteristics of the patients admitted to a forensic psychiatric unit in Portugal, as well as, the psychiatric drugs prescription pattern in this care context.MethodsA retrospective observational study was carried out, through the data analysis of patients admitted to the Sobral Cid Forensic Psychiatry unit of the Coimbra Hospital and University over the past 12 years.ResultsThe sample had 194 inpatients, 153(78.9%) male and 41(21.1%) females. The mean age was 43.3 years and 74.7% had no professional, school or occupational activity. The most frequent psychiatric diagnoses were psychotic disorders (56.7%) and neurodevelopmental disorders(33.5%). 24.2% had at least two psychiatric diagnoses and 38.7% had concomitant medical conditions. 77.8% had history of psychiatric hospitalizations and 21.6% had history of self-injurious behaviors. 37.1% of the sample had a criminal record. Crimes against people were the most frequent. The use of injectable antipsychotic formulations was frequent and 18.6% of the patients were medicated with Clozapine. The prescribed daily doses were above the defined daily dose. Psychotic disorders and addictive disorders were less frequent in women. Statistically significant differences were found in the frequency of homicide between females(41.5%) and males(22.2%).ConclusionsTailored solutions are crucial to accomplish the purpose of security measures, mostly by addressing the identified needs and rethinking the approach on this specific context.DisclosureNo significant relationships.KeywordForensic Psychiatry Units

Abstract
Introduction Mentalization (MZ) is the capacity by which people make sense of their own’s and others’ mental states; when compromised, it is associated with several mental disorders (Bateman & Fonagy, 2010). A valid instrument to assess MZ is missing and required for the Portuguese population. Objectives To develop and validate a Portuguese version (Questionário de Mentalização – QMZ) of the Mentalization Questionnaire (MZQ) (Hausberg et al., 2012). Methods A sample of 184 Portuguese medical students (mean age = 21.6 ± 2.47 years, 59.8% female) was used to explore the psychometric properties of the scale, using reliability and factor analysis (varimax rotation method). Results The QMZ exhibited a Cronbach’s alpha score of .80. All items contributed to its reliability. Based on the scree plot of Cattell and interpretability of items, a 2-factor and a 5-factor structures were further explored. The former explained 38.8% of the total variance (VE) and included a regulation of affect (VE= 27.3%, α=.79) and a self-reflection and emotional awareness (VE= 11.5%, α=.62) factors. The latter explained 60.6% of the total variance and incorporated the following dimensions: self-control (VE= 27.3%, α=.74), daily relationships (VE= 11.5%, α=.67), self-comprehension (VE= 8.1%, α=.54), close relationships (VE= 7.0%, α=.41) and self-monitoring (VE= 6.7%, α=.52). The 5-factor structure was closer to the dimensional concept of mentalization. Conclusions The QMZ has proved to be a promising instrument, with adequate psychometric properties, confirmed by its acceptable construct, criterion and factorial validity and reliability to assess mentalization in Portuguese language.

Abstract
IntroductionThe Perinatal period is a time of vulnerability for developing psychiatric disorders of higher prevalence in the female gender - depression and anxiety1. Numerous authors have proposed that maternal psychological factors could influence pregnancy course and the well-being of mother and newborn2.ObjectivesTo explore the relationship between perinatal psychological disorder and physiological parameters evaluated at birth, such as the Apgar Index (AI; 1, 5 and 10 minutes), head circumference, weight, length and age.Methods533 women answered, in the second trimester of pregnancy (16.98±4.83 weeks of gestation), several questions about psychosocial variables, the Perinatal Depression Screening Scale3 and the Perinatal Anxiety Screening Scale4. Of these, 208 (39.0%) women were interviewed with the Diagnostic Interview for Psychological Distress5. Newborn physiological parameters were obtained from electronic health records.ResultsAI was significantly (p<.01) and moderately (r≈.25) correlated with maternal anxious symptomatology, and with the experience of a stressful event in the last year (only AI 1 minute). Newborns of women with clinically relevant anxious symptomatology (>cutoff point, 14.6%) had significantly lower AI (p<.05), which was also observed in newborns of women who considered having had a stressful event (only AI 1 minute). Women’s newborns with maternal anxiety disorders during pregnancy (5.3%), had significantly lower values in AI, head circumference, weight and age of birth. Regression analyses showed that anxiety in pregnancy (symptoms and/or diagnoses) is a predictor of newborn physiological parameters, explaining significant percentages(r≈22%; p<.05) of its variability.ConclusionsEarly detection of psychological disorders in pregnancy, namely anxiety, is determinant to prevent adverse neonatal outcomes.DisclosureNo significant relationships.

Abstract
Introduction Screening programs for perinatal depression are systematicly implemented in developed countries. To circumvent the most commonly pointed limitation by the primary healthcare professionals (the questionnaires length), we have developed shorter forms of the Beck and Gable Postpartum Depression Screening Scale-35. The shortest version consists of seven items, each one representing a dimension evaluated by the PDSS. This PDSS-7 demonstrated equal levels of reliability and validity as the 35-item PDSS with the advantage of being completed in as little as 1-2 minutes(Pereira et al. 2013). Objectives To analyze the construct validity of the PDSS-7 using Confirmatory Factor Analysis, to use both in Portugal and in Brazil. Methods The Portuguese sample was composed of 616 women (Mean age: 32.29±4.466; Mean gestation weeks=17.13±4.929). These participants were not the same who participated in the psychometric study that led to the selection of the seven items. The Brazilian sample was composed of 350 women (Mean age: 30.01±5.452; Mean gestation weeks=25.17±6.55). They all had uncomplicated pregnancies and completed the European/Brazilian Portuguese versions of PDSS-24 (Pereira et al. 2013/ Barros et al. 2021), which was composed of the same items and included the seven items that compose the PDSS-7. Results The unidimensional model of PDSS-7 presented a good fit in both samples (Portuguese/Brazilian: χ2/d.f.=3.439/2.653; RMSEA=.066/.069, CFI=.974/.981, TLI=.947/.957, GFI=.939/.957; p<.001). The PDSS-7 Cronbach’s alphas were .82/.83 and all the items contribute to the internal consistency. Conclusions The PDSS-7 is a valid and precise, economic, fast and easy screening instrument for perinatal depression, a major public health problem, both in Portugal and in Brazil.

Abstract
Introduction Postpartum depression (PPD) is the commonest postpartum psychiatric condition, with prevalence rates around 20%1. PPD is associated with a range of adverse outcomes for both the mother and infant2. Therefore, identifying modifiable risk factors for perinatal depression is an important public health issue3. Objectives To explore the role of dysfunctional attitudes towards motherhood in postpartum depressive symptoms and disorder. Methods 247 women were evaluated in the third (12.08±4.25 weeks) and sixth months (31.52± 7.16 weeks) postpartum with the Attitudes Towards Motherhood Scale4, the Postpartum Depression Screening Scale5 and the Diagnostic Interview for Psychological Distress-Postpartum6. Correlation analysis was performed followed by linear/logistic regression analysis when the coefficients proved significant (p<.05), using SPSS. Results Dysfunctional beliefs towards motherhood concerning judgement by others and maternal responsibility positively correlated with depressive symptoms at the third (.528; .406) and the sixth months (.506; .492) postpartum. Those dysfunctional beliefs were predictors of depressive symptoms at the third (ß=.440; ß=.151) and sixth months (ß=.322; ß.241) explaining 29.4% and 30.2% of its variance, respectively. Having dysfunctional beliefs at the third month significantly increase the likelihood of being diagnosed with Major Depression (DSM5) both in the third (Wald=9.992, OR=1.169; Wald=16.729, OR=1.231) and sixth months (Wald=5.638, OR=1.203; Wald=7.638, OR=1.301) (all p<.01). Conclusions Cognitive distortions should be included in the assessment of risk factors for PPD. Early identification of women presenting motherhood-specific cognitive biases may be crucial for implementing preventive interventions favoring a more positive and healthier motherhood experience.

Abstract
IntroductionMotherhood-related beliefs are characterized by themes of failure and maternal role idealization. Recent studies found that postpartum depression/PPD is both predicted and a predictor by/for dysfunctional beliefs/DB. Additionally, it is possible that when contextual factors (eg. lack of social support) are present, women may anticipate the parenting experience as being of isolation, which in turn can lead to more dysfunctional attitudes.ObjectivesTo explore psychosocial risk factors for motherhood-DB.Methods233 women were evaluated in the second trimester (17.05±4.82 weeks) of pregnancy and in the third month (12.08±4.25 weeks) postpartum sociodemographically and psychosocially (years of education, previous children and social support) and the Portuguese validated self-report questionnaires to assess: perinatal depression; perinatal anxiety; perfectionism; negative affect; self-compassion; and repetitive negative thinking (all in T0). The Attitudes Towards Motherhood Scale was administered in the postpartum. When Pearson/Spearmen correlation coefficients proved significant (p<.05), linear/logistic (hierarchic) regression analysis were performed.ResultsMotherhood-DB correlated significantly with all the variables, except for years of education, Other-oriented-Perfectionism and Common-Humanity. Motherhood-DB were significantly higher in women without previous children (p<.05). The final regression model was statistically significant (p<.001) explaining 15% of the Motherhood-DB variance, with Socially-Prescribed-Perfectionism and social support being the only statistically significant predictors. Hierarchic regression showed that even after controlling for social support, SSP significantly incremented the variance in 9%.ConclusionsOur results highlight the need for preventive approaches to help women understand the origins of their dysfunctional beliefs (perfectionism, the myths of perfect motherhood) and for the promotion of positive cognitions.DisclosureNo significant relationships.

Abstract
Background To study the association between sleep quality and oral health related variables, which still have conflicts in the literature.
Material and Methods This was a population-based case-control study between subjects with versus without sleep disorders from the Brazilian Public Health System (SUS), city of Maringá (N=1,643). Subjects answered self-reported questionnaires: a) Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), b) Sleep Assessment Questionnaire (SAQ) and c) North York Dental Health Survey (NYDHS).
Results No significant difference was found for gender, marital status, or income; however, non-Caucasians, people with lower levels of education, and those between 20 to 50 years old had worse scores of sleep disorders in the SAQ. Self-perceived oral health, masticatory capacity to eat foods, and gingival bleeding was significantly worse among subjects with self-reported sleep disorders. Self-reported tooth loss, edentulism and use of removable partial dentures (with clasps) or complete dentures showed no significant difference between groups. Self-reported sleep disorder subjects presented significantly higher prevalence of both self-reported tooth and TMJ pain.
Conclusions It can be concluded that individuals with self-reported sleep disorders presented worse self-perceived oral health for most studied variables. Key words:Oral health, case control study, sleep; review, gingivitis, periodontitis, tooth loss.

Abstract
The teaching process of auscultation is complex in itself, and difficult to operate since it requires a wide spectrum of patients with the most diverse cardiopulmonary pathologies, readily available during teaching and assessment hours, for an ever-growing number of medical students. In this paper we will focus on how virtual patient technologies can promote the evolution of the current teaching methodologies, promoting better learning. The chosen methodology was: a) a review of available medical simulation technologies for auscultation teaching; b) a case study illustrating how a virtual patient simulation technology has been successfully used to teach and certify auscultation skills. Results show the positive impact and high acceptability of virtual patient simulation technologies in the teaching of auscultation to medical students.

Abstract
INTRODUCTION AND OBJECTIVES Bladder complications may be seen in up to 12% of patients treated with pelvic irradiation. Hyperbaric oxygen therapy (HBOT) is an option for the management of radiation-induced hemorrhagic cystitis (RIHC). The aim of this study was to evaluate the efficacy of HBOT in radiation cystitis and to identify the predictive factors for a successful outcome. MATERIAL AND METHODS We retrospectively reviewed 105 patients diagnosed with RIHC which were treated with HBOT between 2007 and 2016 in our institution. Patients received 100% oxygen in a multiplace hyperbaric chamber at 2.4atm for 80minutes. All patients fulfilled a questionnaire documenting symptom severity pre-HBOT and at the end of the follow-up period. RESULTS After a median of 40 HBOT sessions, there was success rate of 92,4% in the control of hematuria. During our follow-up period (median of 63 months) 24,7% patients presented with recurrence of hematuria. The mean score of the questionnaire-assessed variables: dysuria, urinary frequency and hematuria, was significantly lower after the follow-up period (P<.05). Our data shows that the sooner HBOT is delivered after the first episode of hematuria, better response rates are achieved and lower recurrences concerning hematuria were registered (P<.05). No serious complications were observed. CONCLUSIONS Our results support the safety and long-term benefits of HBOT on RIHC and other distressful bladder symptoms, which represents an expected improvement of quality of life in our patients.

Abstract
Time elapsed between removal from culture and embryo transfer (ET) can have a profound effect on the success of an invitro-produced (IVP) ET program. The embryo culture medium provides the necessary nutrients for embryo development and the use of media with a different nutrient composition to load embryos into straws could negatively affect embryo viability. The objective of the present study was to evaluate the effect of type of media used for embryo loading on pregnancy establishment and maintenance. Holstein heifers (n=800) were synchronized using a modified 5-day CO-Synch + controlled internal drug release (CIDR) as follows: Day −8: CIDR inserted, Day −3: CIDR removed, prostaglandin F2α treatment (500μg cloprostenol sodium), Day 0: gonadotrophin-releasing hormone (GnRH; 100μg of gonadorelin acetate). Five days after GnRH, heifers were evaluated by ultrasonography to determine presence of a corpus luteum (CL). Embryos were removed from culture on Day 7 (Day 0=fertilization), placed into tubes containing SOFaaci, and transported in an incubator (LabMix, WTA) to the transfer facility within 1.5h. Upon arrival embryos were removed from transport tubes and randomly assigned to be loaded into 0.25-mL straws containing either holding media (Vigro Holding Plus) or SOFaaci-HEPES. After loading into straws, embryos were placed in an ET gun and AI gun warmers set at 35°C until transfer by 1 of 5 technicians. Heifers with a CL were randomised for transfer of a fresh IVP embryo loaded into a straw containing either holding media or SOFaaci-Hepes on Day 7±1. Interval from embryo loading to transfer ranged from 1 to 3h. Pregnancy was determined by ultrasonography on Days 32 and 60. Data were analysed by logistic regression and included the fixed effects of loading media, embryo stage, embryo quality, interval between GnRH and ET, and biologically relevant interactions. Pregnancies per ET (P/ET) on Day 32 were not different between the groups in which embryos were loaded using holding media and those which used SOFaaci-Hepes, nor there were interactions between loading medium and embryo stage, embryo quality, or interval from GnRH to ET (P>0.10; Table 1). Pregnancies per ET (P/ET) on Day 60 were not different between the loading media groups, nor were there interactions between loading medium, embryo stage, and embryo quality, or interval from GnRH to ET (P>0.10). Pregnancy loss between Days 32 and 60 was not different between groups, nor there were interactions between loading media groups and any other factor (P>0.10). In conclusion, the use of either holding medium or SOFaaci-HEPES for fresh IVP embryo loading does not affect fertility; thus, both are suitable alternatives for loading of embryos into transfer straws.

Abstract
The aim of this study was to evaluate the effect of ruminal infusion with propylene glycol (PG) on the invitro embryo production (IVEP) of Holstein (Bos taurus) prepubertal heifers (7 to 8 months). For this study, 16 prepubertal heifers were distributed into two groups: Propylene Glycol Group (PGG; n=8) and Control Group (CG; n=7). Additionally, 8 pubertal heifers were used for the positive control group (PUB). All animals (n=23) underwent an ovum pickup (OPU) for follicular ablation on Day 0, followed by an FSH protocol treatment (160mg performed in 4 injections twice a day in decreasing doses, designated as D2PM, D3AM, D3PM, and D4AM). Animals from PGG received a ruminal infusion with 250mL of PG twice a day on Days 0, 1, 2, 3, and 4, using a drench. Animals from CG and PUB did not receive any additional treatment. On Day 5 all animals underwent another OPU, and oocytes were used for the IVEP (Sexing Technologies commercial laboratory). The produced embryos were transferred fresh to Holstein heifer recipients. Additionally, blood sampling was performed on D4PM (M1) and on the day of OPU (D5AM, M2) for insulin-like growth factor (IGF-1, via radioimmunoassay) and glucose (hexokinase) analysis. Data were analysed using the GLIMMIX procedure of SAS. No difference was observed between groups for number of recovered oocytes (CG: 14.28±1.9; PGG: 14.87±3.9; PUB: 10.50±2.2; P=0.24), number of viable oocytes (CG: 10.71±2.5; PGG: 10.75±2.7; PUB: 9.50±2.0; P=0.80), cleaved oocytes (CG: 7.71±1.5; PGG: 9.50±2.1; PUB: 6.25±1.4; P=0.14), cleavage rate (CG: 54.2% (7.7 out of 14.2); PGG: 64.1% (9.5 of 14.8); PUB: 59.0% (6.2 of 10.5); P=0.35) and number of blastocysts (CG: 1.71±0.5; PGG: 2.00±0.6; PUB: 3.12±1.0; P=0.71). Pubertal heifers had higher blastocyst rates compared with prepubertal heifers, regardless of PG treatment (CG: 11.9% (1.7 of 14.2); PGG: 13.5% (2 of 14.8); PUB: 29.5% (3.1 of 10.5); P=0.01). No difference was observed between groups for 30-day (CG: 41.7% (5 of 12); PGG: 46.7% (7 of 15); PUB: 42.9% (6 of 14); P=0.96) or 60-day pregnancy rates (CG: 41.7% (5 of 12); PGG: 33.3% (5 of 15); PUB: 42.9% (6 of 14); P=0.86). In addition, no difference was observed for pregnancy loss between 30 and 60 days (CG: 0.0% (0 of 12); PGG: 13.3% (2 of 15); PUB: 0.0% (0 of 14); P=0.99). Regarding metabolic blood analysis, no difference was observed for IGF-1 (ngmL−1) between groups (P=0.38), moment of sample collection (P=0.06), and interaction of group×moment (P=0.87; CG/M1: 263.36±15.2; CG/M2: 297.71±18.7; PGG/M1: 304.25±26.9; PGG/M2: 332.61±31.6; PUB/M1: 309.16±19.9; PUB/M2: 311.07±18.8). Glucose (mg dL−1) was higher (P=0.0001) for pubertal heifers (91.63±1.4) compared with the other groups (CG: 102.25±1.1; PGG: 107.71±3.5); however, no difference was observed for moment of sample collection (P=0.35) or interaction of group×moment (P=0.36). These data show that treatment with PG was not efficient to improve the IVEP of prepubertal Holstein heifers, embryos from prepubertal heifers treated with PG did not have increased pregnancy rate, and treatment did not increase IGF-1 or glucose blood levels.

Abstract
The timing of initiation of superstimulatory treatments relative to follicle wave emergence has been shown to affect ovulatory response and invivo embryo production. The significant increase of invitro embryo production (IVP) and the possibility of using pregnant animals as oocyte donors has created the need to optimise superstimulatory treatments for IVP in pregnant cattle. Thus, the objective of the present study was to evaluate the effect of synchronisation of follicle wave emergence before superstimulation for ovum pickup (OPU) and IVP in pregnant heifers. Pregnant (47-62 days of gestation) Holstein heifers (n=28) 19.5±0.3 months of age were assigned in a completely randomised design to one of two groups: synchronisation of follicular wave emergence by dominant follicle removal (DFR; all follicles >6mm) or untreated control (no DFR). Superstimulatory treatments were initiated 36h after DFR or at random stages of the follicular wave in the no-DFR group and consisted of the administration of 160mg of purified FSH (Folltropin-V, Vetoquinol) over four injections 12h apart as follows: 48.0, 42.7, 37.3, and 32.0mg. Ovum pickup was performed in all heifers 40h after the last purified FSH injection. Heifers were subjected to OPU for oocyte recovery, and the number of follicles was determined. Recovered oocytes were processed in groups by treatment, and IVP was performed. Differences between treatment groups were evaluated using generalised linear mixed models. Results are presented in Table 1 and are expressed as means±s.e.m. for data collected at the time of OPU or as proportions for embryo production results. The number of small follicles (<6mm) at the time of OPU was greater in the no-DFR group than in the DFR group (P=0.04). Conversely, there were no differences between treatments in the number of medium follicles (6-10 mm; P=0.17), large follicles (>10 mm; P=0.11), total follicles (P=0.93), total number of recovered oocytes (P=0.4), or number of viable oocytes (P=0.53). The mean oocyte percentage recovery rate was not different between heifers in the DFR (53.6±4.7%) and no-DFR (56.5±4.7%) groups (P=0.52). Both cleavage and blastocyst rate were greater (P<0.008) in the DFR group than in the no-DFR group; as a result, the number of transferable embryos per animal was 5.6 in the DFR group and 2.8 in the no-DFR group. In summary, initiation of superstimulatory treatments at the time of follicle wave emergence improves cleavage and blastocyst rates, thus leading to greater embryo production.

Abstract
Abstract
Aims
The Acute Cardiac Care Association (ACCA)–European Association of Percutaneous Coronary Intervention (EAPCI) Registry on ST-elevation myocardial infarction (STEMI) of the EurObservational programme (EORP) of the European Society of Cardiology (ESC) registry aimed to determine the current state of the use of reperfusion therapy in ESC member and ESC affiliated countries and the adherence to ESC STEMI guidelines in patients with STEMI.
Methods and results
Between 1 January 2015 and 31 March 2018, a total of 11 462 patients admitted with an initial diagnosis of STEMI according to the 2012 ESC STEMI guidelines were enrolled. Individual patient data were collected across 196 centres and 29 countries. Among the centres, there were 136 percutaneous coronary intervention centres and 91 with cardiac surgery on-site. The majority of centres (129/196) were part of a STEMI network. The main objective of this study was to describe the demographic, clinical, and angiographic characteristics of patients with STEMI. Other objectives include to assess management patterns and in particular the current use of reperfusion therapies and to evaluate how recommendations of most recent STEMI European guidelines regarding reperfusion therapies and adjunctive pharmacological and non-pharmacological treatments are adopted in clinical practice and how their application can impact on patients’ outcomes. Patients will be followed for 1 year after admission.
Conclusion
The ESC ACCA-EAPCI EORP ACS STEMI registry is an international registry of care and outcomes of patients hospitalized with STEMI. It will provide insights into the contemporary patient profile, management patterns, and 1-year outcome of patients with STEMI.

Abstract
The spin S=1/2 Kitaev honeycomb model has attracted significant attention since emerging candidate materials have provided a playground to test non-Abelian anyons. The Kitaev model with higher spins has also been theoretically studied, as it may offer another path to a quantum spin liquid. However, a microscopic route to achieve higher spin Kitaev models in solid state materials has not been rigorously derived. Here we present a theory of the spin S=1 Kitaev interaction in two-dimensional edge-shared octahedral systems. Essential ingredients are strong spin-orbit coupling in anions and strong Hund's coupling in transition metal cations. The S=1 Kitaev and ferromagnetic Heisenberg interactions are generated from superexchange paths. Taking into account the antiferromagnetic Heisenberg term from direct-exchange paths, the Kitaev interaction dominates the physics of the S=1 system. Using an exact diagonalization technique, we show a finite regime of S=1 spin liquid in the presence of the Heisenberg interaction. Candidate materials are proposed, and generalization to higher spins is discussed.

Abstract
Abstract
Background
The addition of carboplatin to an anthracycline/taxane-based chemotherapy(CT) in neoadjuvant setting has been suggested to improve pathological complete response(pCR) in TNBC. However, the impact of pCR in prognosis is unknown. We aim to study the value and feasibility of the addition of carboplatin in neoadjuvant setting.
Methods
Demographic and clinical data of TNBC patients treated with neoadjuvant CT in a comprehensive cancer center between 2010-2018 were retrospectively collected. Two cohorts were defined: one treated with Carboplatin/Paclitaxel followed by dose-dense Doxorrubicin/Cyclophosphamide(CP-AC) and other with AC followed by Docetaxel(AC-D). Median follow-up time was 3.1 and 6.9 years, respectively. pCR was defined as absence of residual invasive tumor in breast/axilla. Survival analysis using Kaplan-Meier method and Cox proportional-hazards model were applied. Statistical significance was set at p<0.05.
Results
One-hundred and sixty patients were enrolled: 78 CP-AC and 38 AC-D. Groups were balanced regarding patients and tumor characteristics with exception of pre-menopausal status, more frequent in CP-AC(68% vs 47%;p=.04). Age at diagnosis was 47(28-76)years, the majority had ECOG 0(92%) ductal carcinomas(82%), clinicalT2/3 stages(76%), grade 3(81%) with lymph node involvement(N+)(57%). 14% had Inflammatory breast cancer(IBC)(CP-AC 14%;AC-D 13%; p=.9).
Neutropenia was the most prevalent adverse event(G3/4: CP-AC 61%;AC-D 16%;p=.02), 12% and 16% of febrile neutropenia(p=.8). G3/4 thrombocytopenia occurred only in CP-AC(6%). Hypersensitivity reactions were more prevalent in CP-AC(19% vs 2.7%;p=.02), majority to paclitaxel, all G1/2. Hospital admission occurred in 12%(CP-AC 13%;AC-D 9%; p=.8). There were no treatment-related deaths. Treatment schedule was complete in 89%(CP-AC 87%;AC-D 92%;p=.5), with 20% dose reductions(CP-AC 25%;AC-D 11%;p=0.9).
pCR was achieved in 42%(CP-AC 50%;AC-D 28%;p=.03). 1- and 3-year disease-free survival(DFS) was 94%/85% for CP-AC and 72%/58% for AC-D(p=.3). Risk of recurrence was higher in IBC(HR 25.1;CI95% 7.7-81.3;p<.0001), N+ disease(HR 3.6;CI95% 1.2-10.5;p=.02) and non-pCR(HR 10.9;CI95% 2.3-52.3,p=.003). N+ disease was associated with higher recurrence only in AC-D(HR 11.7;CI95% 1.3-104;p=.03).
Cancer-related deaths were 20%(CP-AC 10%;AC-D 40%;p=.001). 1- and 2-year overall survival (OS) was 99%/95% for CP-AC and 70%/61% for AC-D(p=.06). N+ disease was associated with higher risk of death in AC-D(HR 6.3;CI95% 1.1-24.6;p=.04). Risk of death was independently associated with IBC(HR 4.1;CI95% 2.1-18.7; p=.001) but not with N+ disease(HR 2.7;CI95% 0.8-9.5;p=.13) or pCR(HR 4.1;CI95% 0.9-19.7;p=.08) although pCR was statistically significant in univariate analysis (1- and 2-year OS 97% vs 92% and 94% vs 86% for pCR and non-PCR;p=.003).
Conclusions
Carboplatin addition clearly increased pCR with a trend to DFS and OS benefit. This regimen was associated with more, nevertheless manageable, adverse events with most of the patients able to tolerate and complete the full-dose regimen. Though we did not find a subgroup of patients that benefit with carboplatin regimen, we should consider avoiding AC-D at least in N+ disease.

Abstract
Biofouling represents a major economic, environmental and health concern for which new eco-friendly solutions are needed. International legislation has restricted the use of biocidal-based antifouling coatings, and increasing efforts have been applied in the search for environmentally friendly antifouling agents. This research work deals with the assessment of the interest of a series of synthetic chalcone derivatives for antifouling applications. Sixteen chalcone derivatives were synthesized with moderate yields (38-85%). Antifouling bioactivity of these compounds was assessed at different levels of biological organization using both anti-macrofouling and anti-microfouling bioassays, namely an anti-settlement assay using mussel (Mytilus galloprovincialis) larvae, as well as marine bacteria and microalgal biofilms growth inhibition bioassays. Results showed that three compounds (11, 12, and 16) were particularly active against the settlement of mussel larvae (EC50 7.24-34.63 μM), being compounds 12 and 16 also able to inhibit the growth of microfouling species (EC50 4.09-20.31 μM). Moreover, the most potent compounds 12 and 16 were found to be non-toxic to the non-target species Artemia salina (<10% mortality at 25 μM). A quantitative structure-activity relationship model predicted that descriptors describing the ability of molecules to form hydrogen bonds and encoding the shape, branching ratio and constitutional diversity of the molecule were implied in the antifouling activity against the settlement of mussel larvae. This work elucidates for the first time the relevance of synthesizing chalcone derivatives to generate new non-toxic products to prevent marine biofouling.

Abstract
There are several electronic stethoscopes available on the market today, with a very high potential for healthcare namely telemedicine, assisted decision and education. However, there are no recent comparatives studies published about the recording quality of auscultation sounds. In this study we aim to: a) define a ranking, according to experts opinion of 6 of the most relevant electronic stethoscopes on the market today; b) verify if there are any relations between a stethoscope's performance and the type of pathology present; c) analyze if some pathologies are more easily identified than others when using electronic auscultation. Our methodology consisted in creating two study groups: the first group included 18 cardiologists and cardiology house officers, acting as the gold standard of this work. The second included 30 medical students. Using a database of heart sounds recorded in real hospital environments, we applied questionnaires to observers from each group. The first group listened to 60 cardiac auscultations recorded by the 6 stethoscopes, and each one was asked to identify the pathological sound present: aortic stenosis, mitral regurgitation or normal. The second group was asked to choose, between two auscultation recordings, using as criteria the best sound quality for the identification of pathological sounds. Results include a total of 1080 evaluations, in which 72% of cases were correctly diagnosed. A detailed breakdown of these results is presented in this paper. As conclusions, results showed that the impact of the differences between stethoscopes is very small, given that we did not find statistically significant differences between all pairs of stethoscopes. Normal sounds showed to be easier to identify than pathological sounds, but we did not find differences between stethoscopes in this identification.

Abstract
Background Lower urinary tract infections are common in dogs, and Escherichia coli is the most common bacterial pathogen isolated. The literature has conflicting evidence regarding the inhibitory effects of urine concentration and pH on E. coli growth. Hypothesis/Objectives To determine the effect of different pH and urine concentrations on E. coli growth in vitro. Animals Voided urine samples from 10 apparently healthy spayed female dogs were used. Methods A matrix of 9 urine specific gravity (USG; 1.010, 1.020, and 1.030) and pH (5.5, 7.0, and 8.5) combinations was prepared by diluting and titrating filtered voided urine samples. Three E. coli isolates were obtained from urine of female dogs with signs of lower urinary tract infection and cultured at different urine pH and USG combinations in wells of a microtiter plate. The number of E. coli colony‐forming units (CFU) per mL of urine was calculated after aerobic incubation of the urine at 37°C for 18 hours, and statistically compared. Results Significant differences were identified in the mean log CFU/mL among different combinations of pH and USG. The lowest log CFU/mL were observed in alkaline concentrated urine (pH 8.5 and USG 1.030). Conclusions and Clinical Importance Escherichia coli in vitro growth was higher in neutral to acidic and diluted urine compared to alkaline and concentrated urine. The impact of non‐alkalizing diluting diets on the incidence of E. coli lower urinary tract infections should be further explored.
