Abstract
INTRODUCTION The diagnosis and severity assessment of COPD relies on spirometry, and in particular the FEV1. However, it has been proposed that hyperinflation and air-trapping are better predictors of exercise capacity and mortality than the FEV1. RESEARCH QUESTION: Does static hyperinflation predict exercise capacity? METHODS We conducted an observational prospective study. Patients with COPD referred to the lung function laboratory were consecutively recruited. Patients with hyperinflation (the experimental group) were compared to patients without hyperinflation (the control group). The sample sizes were determined assuming an effect size of 0.5 and a power of 0.80. RESULTS We recruited 124 participants, of whom 87% were male, the mean age was 66.1 ± 8.8 years. 67% were symptomatic (GOLD B or D). Airflow limitation was moderate to severe in the majority of patients (median FEV1 47%, IQR 38-65%) and 43% of patients had static hyperinflation. The median 6MWD was 479 meters (404-510) and peak workload in CPET was 64 watts (46-88) with peak VO2 1.12 L/min, 0.89-1.31 L/min. Patients with lower FEV1, DLCO and IC/TLC and higher RV/TLC had reduced exercise capacity in both 6MWT and CPET, measured as lower distance, greater desaturation and ∆Borg dyspnoea, and reduced workload, peak VO2 and peak VE and higher desaturation and ventilatory limitation (VE/MVV). An IC/TLC < 0.33 predicted reduced exercise performance (peak O2 <60%). Dyspnoea assessed by mMRC and QoL measured by CAT and CCQ were also worse in the hyperinflation in COPD patients. CONCLUSION In COPD patients, IC/TLC and RV/TLC are valuable predictors of exercise performance in both 6MWT and CPET and PRO.

Abstract
PURPOSE/OBJECTIVE(S) Magnetic resonance linear accelerator (MRL) systems permit acquisition of novel imaging at the time of radiotherapy. A validated MR hypoxia imaging biomarker could select patients for adaptive radiotherapy with hypoxia modification or dose escalation. The aims of this study were (1) to develop a protocol for quantitative hypoxia sensitive MRI (2) to validate these in prostate cancer (PCa) against pimonidazole-stained prostatectomy sections. MATERIALS/METHODS Blood oxygen level dependent (BOLD), intravoxel incoherent motion (IVIM), oxygen-enhanced (OE) and dynamic contrast enhanced (DCE) MRI were used. Sequences were developed on a diagnostic 1.5 T MR (MRD) and MRL with healthy volunteers and PCa patients. The Hyprogen trial includes men with localized PCa scheduled for prostatectomy. Imaging is acquired twice prior to surgery and oral pimonidazole is taken 8-16 hours before surgery. Whole prostate (WP) and dominant prostatic lesion (DIL) were outlined on T2-weighted (T2W) images and a 'normal prostate' (NP) volume created by subtracting DIL from WP. Contours were applied to parametric maps from the quantitative MRI, with median and IQR extracted. Patient-specific 3D-printed prostate molds were created from WP volumes and used to guide prostate whole organ dissection. RESULTS Three of 20 patients recruited to date. MRI data were acquired successfully. A personalized prostate mold was produced for each patient and facilitated dissection of the prostatectomy specimen in a matching plane to MRI to validate hypoxia detection of the MR protocol. Correlation with pimonidazole staining is underway. Imaging parameter median values for NP and DIL acquired on MRD and MRL for the first patient are shown (Table 1). The expected differences between NP and DIL for T1 and D are seen and median values for T2* are consistent with reported values in the literature. CONCLUSION The MR hypoxia protocol can be acquired safely and is well-tolerated on the MRL. Once validated against pimonidazole staining adaptive radiotherapy protocols will be developed to use this information.

Abstract
The use of new psychoactive substances has been increasing and constitutes a social and public health problem, and hence, toxicological analysis has become of utmost importance for the detection of such substances. In this article, we present the development and full validation of a simple, user and environmentally friendly, cheap and suitable method for the determination of ketamine and its main metabolite norketamine in hair samples. The procedure included using a miniaturized procedure-microextraction by packed sorbent with mixed-mode sorbent-for sample clean-up. Organic solvents use was minimal, and it was possible to obtain a linear method (0.05-10 ng/mg for both analytes). The extraction efficiency ranged from 32 to 61%, which did not impair sensitivity. The method proved to be selective, precise, accurate and suitable for routine analysis for the determination of said compounds in 50-mg hair samples.

Abstract
OBJECTIVES To assess the efficacy of two cardiac biomarker assays (N-terminal pro-BNP and his sensitivity Troponin I (Beckman Coulter Access)) in detecting Dobermann dilated cardiomyopathy. MATERIALS AND METHODS Dobermanns undergoing cardiac biomarker testing were screened by echocardiography and Holter monitoring, then assigned to a group: normal, equivocal, arrhythmia form of dilated cardiomyopathy, echocardiographic form of dilated cardiomyopathy or both. Some were reassessed to identify final status. Initial cardiac biomarker results were compared to final status. Receiver operating characteristic curves were used to identify area under the curve and corresponding sensitivity (Se), specificity (Sp) for different cut-offs (CO) for each cardiac biomarker. RESULTS A total of 118 Dobermanns with cardiac biomarker data had echocardiography/Holter assessment. Repeat assessment was carried out in 47 Dobermanns after 394.5 ±151.0 days. Seventeen dogs changed group between initial and final status. The final status of 59 was normal, nine were equivocal and 50 had dilated cardiomyopathy (prevalence 42.4%). Of the dilated cardiomyopathy group, 25 had dilated cardiomyopathy-both, 13 dilated cardiomyopathy-echocardiography and 12 dilated cardiomyopathy-Holter. Receiver operating characteristic area under the curve=0.807 for N-terminal proBNP (Se 0.69 and Sp 0.81) and 0.873 for high-sensitivity cardiac Troponin I (Se 0.77 and Sp 0.86). When both Se and Sp were optimised for all forms of dilated cardiomyopathy, N-terminal proBNP cut-off was 626 pmol/L (Se and Sp 0.79) and high-sensitivity cardiac Troponin I cut-off was 0.056 ng/mL (Se and Sp 0.84). Receiver operating characteristic area under the curve was higher for dilated cardiomyopathy-echocardiography (NT-proBNP 0.883; high-sensitivity cardiac Troponin I 0.907) than dilated cardiomyopathy-Holter. CLINICAL SIGNIFICANCE Cardiac biomarker screening may be useful to select Dobermanns which would benefit from further assessment by echocardiography and Holter.

Abstract
In dogs, balloon valvuloplasty is considered the treatment of choice for severe pulmonary valve stenosis, and this technique is currently performed routinely in specialist referral practices with low morbidity and mortality. Stent angioplasty has also been recently proposed as a viable treatment option. The present case series describes the clinical course of four dogs with severe pulmonary valve stenosis, treated with balloon valvuloplasty or stent angioplasty at four different institutions, which developed non-cardiogenic pulmonary oedema perioperatively after apparently successful dilation of the pulmonary valve. In three cases, there was evidence of some degree of pulmonary hypertension before ballooning. Despite intensive care, the complication proved fatal in three cases. Clinicians should therefore be aware of this life-threatening complication, previously undescribed in dogs.

Abstract
Abstract
Background
Annual influenza vaccine uptake is recommended by the Portuguese General-Directorate of Health to certain priority groups. In 2020, amidst the COVID-19 pandemic, some exceptional measures were adopted to operationalize the Portuguese influenza vaccination campaign, like the extension and phasing of the vaccination period. No major changes were introduced in the vaccination of healthcare workers. In Baixo Tâmega health cluster (Portugal), it was perceived that these workers' vaccine uptake had markedly increased in 2020-2021. This study aims to compare their influenza vaccination coverage rates in 2020-2021 to the last 10 seasons.
Methods
A cross-sectional study of the vaccine uptake among the health workers of Baixo Tâmega health cluster was developed. A descriptive analysis was carried out, calculating annual influenza vaccination coverage rates from 2010-2011 to 2020-2021, in doctors, nurses and other health workers. Inferential analysis was performed through chi-squared tests in IBM SPSS Statistics 27.0.1.0., considering significant p-values<0.05.
Results
The difference between health workers 2020-2021's influenza coverage rate and the last season's average rates was 22.81%. Before 2020-2021, average vaccination coverage rates were 51.60% (standard deviation 7.34%, 44.26-58.94%), 60.44% (standard deviation 4.12%, 56.32-64.56%) and 51.20% (standard deviation 7.66%, 43.54-58.86%), in doctors, nurses and other health workers, respectively. In 2020-2021, vaccination rates significantly increased to 79.34%, 79.52% and 74.24% in doctors, nurses and others, respectively (p < 0.001).
Conclusions
Influenza vaccination uptake increased in 2020-2021 among health workers. Further studies should be developed to evaluate this tendency on a larger scale and to better understand its associated factors, which could have been unstructured awareness-raising campaigns, perception of protection against COVID-19 or avoidance of COVID-19-like symptoms and coinfection.
Key messages
Influenza vaccination coverage rates increased in 2020-2021 among the healthcare workers of a Portuguese health cluster. The COVID-19 pandemic may have contributed to the increase in the influenza vaccination coverage rates.

Abstract
Introduction Due to the current global background of the COVID-19 pandemic, mental health is an important factor to be promoted. In spite of the subjectivity of the psychological impact brought by this pandemic, the population has undergone several sudden and meaningful changes in psychic integrity. Therefore, the League of Psychiatry and Mental Health of a Brazilian public university emerges with the aim of complementing the curriculum of Psychiatric Medicine, along with promoting mental health inside and outside the university. Objectives Hold online events and disseminate informative material to help students, mental health professionals and general community interested in the topic. Methods The League did a member recruitment with academics from different health areas, who prepared and published booklets and folders with informations promoting mental health. And also, promoted speeches on online platforms from May 2020 to October 2020 with psychiatrists, psychologists and renowned professionals in Brazil. Results Eighteen lectures were held on topics such as “Grief in the pandemic and its implications in mental health”; “Preventing suicide in the pandemic”, among others, that had a relevant role for those who were in a vulnerable emotional state at the time. As for publications, a national reach was possible, which served as a source for the cultivation of a good psychic health to face the pandemic. Conclusions More than 13.600 people participated in the promoted proposals, In addition to providing positive feedbacks to the League, with the improvement of knowledge in the field of Psychiatry and Mental Health, reaching the proposed objectives.

Abstract
Ventricular preexcitation secondary to anterograde conduction through an accessory pathway was diagnosed in two Golden Retriever dogs. Both dogs demonstrated similar segmental myocardial thinning and systolic dyskinesia of the basal interventricular wall on echocardiography. These changes are widely recognised in people with ventricular preexcitation but have not been previously described in dogs. Ventricular preexcitation should be considered as a potential cause for segmental wall motion abnormalities in these two dogs.

Abstract
OBJECTIVES To identify the predictive value on time to onset of heart failure (HF) or cardiac death of clinical, radiographic, and echocardiographic variables, as well as cardiac biomarkers N-terminal pro brain natriuretic peptide (NT-proBNP) and cardiac troponin I in dogs with preclinical myxomatous mitral valve disease (MMVD). ANIMALS One hundred sixty-eight dogs with preclinical MMVD and left atrium to aortic root ratio ≥1.6 (LA:Ao) and normalized left ventricular end-diastolic diameter ≥1.7 were included. METHODS Prospective, randomized, multicenter, single-blinded, placebo-controlled study. Clinical, radiographic, echocardiographic variables and plasma cardiac biomarkers concentrations were compared at different time points. Using receiving operating curves analysis, best cutoff for selected variables was identified and the risk to develop the study endpoint at six-month intervals was calculated. RESULTS Left atrial to aortic root ratio >2.1 (hazard ratio [HR] 3.2, 95% confidence interval [95% CI] 1.9-5.6), normalized left ventricular end-diastolic diameter > 1.9 (HR: 6.3; 95% CI: 3.3-11.8), early transmitral peak velocity (E peak) > 1 m/sec (HR: 3.9; 95% CI: 2.3-6.7), and NT-proBNP > 1500 ρmol/L (HR: 5.7; 95% CI: 3.3-9.5) were associated with increased risk of HF or cardiac death. The best fit model to predict the risk to reach the endpoint was represented by the plasma NT-proBNP concentrations adjusted for LA:Ao and E peak. CONCLUSIONS Logistic and survival models including echocardiographic variables and NT-proBNP can be used to identify dogs with preclinical MMVD at higher risk to develop HF or cardiac death.

Abstract
Holter monitoring has an important role in the diagnosis of cardiac arrhythmias in dogs with underlying heart disease or clinical signs such as intermittent weakness/ collapse or exercise intolerance, and in the assessment of antiarrhythmic treatment efficacy. A typical recording lasts for 24 h, although 48 h or any number of days up to 7 are possible, especially when investigating clinical signs that may not happen during the first 24 h. The objective of this study was to review retrospectively a large number of 48 h Holter recordings obtained from dogs to assess the possible incremental diagnostic yield of the second 24 h period in comparison to the first 24 h. Three hundred and fifty four 48 h Holter recordings were included in the study for analysis. A 48 h Holter recording contributed to a 14.5% increase in the likelihood of documenting the cardiac rhythm during an event of interest; a 24 h recording increased the diagnostic yield from 32.2% to 46.7%. When the recordings were grouped according to the most important rhythm abnormalities (supraventricular arrhythmias group, ventricular arrhythmias group, bradyarrhythmias group, no arrhythmias group), the 48 h Holter monitor contributed to a 5% increase in the likelihood of identifying a relevant cardiac rhythm abnormality, increasing the diagnostic yield from 58% to 63%. This benefit occurred mostly in dogs with iterative or paroxysmal supraventricular arrhythmias. In dogs with bradyarrhythmias or ventricular arrhythmias, an additional 24 h of analysis was useful in only a limited number of cases.

Abstract
Short, valid and easy to use tools are needed to monitor non-invasive ventilation in clinical practice and for organization of home mechanical ventilation services. The aim of this study was to develop a professional translation and cultural adaptation of the Portuguese S3 non-invasive ventilation questionnaire. 234 stable patients (128 male patients, 53.8%) with a mean age of 69.3 years under long-term home non-invasive ventilation were recruited from a single-center outpatient clinic. The most frequent diagnostic groups were obesity hypoventilation syndrome, chronic obstructive pulmonary disease and restrictive chest wall disorders. The Portuguese version of the questionnaire was obtained using translation back-translation process with two professional translators. Internal consistency for the total score was good (Cronbach's α coefficient of 0.76) as well as for the "respiratory symptoms" and the "sleep and side effects" domains (Cronbach's α coefficient=0.68 and Cronbach's α coefficient=0.72, respectively). An exploratory factor analysis was performed leading to an explained variance of 54.6%, and resulted in 3 components. The Portuguese version of the S3-NIV questionnaire is a simple and valid tool for the routine clinical assessment of patients receiving home NIV.

Abstract
BACKGROUND The Lung Cancer Screening Trial demonstrated improved overall survival (OS) and lung cancer specific survival (LCSS), likely due to finding early-stage NSCLC. The purpose of our investigation is to evaluate whether long-term surveillance strategies (4+ years after surgical resection of the initial lung cancer(1LC)) would be beneficial in NSCLC patients by assessing the rates of second lung cancers(2LC) and the OS/LCSS in patients undergoing definitive surgery in 1LC as compared to 2LC (>48 months after 1LC) populations. METHODS SEER13/18 database was reviewed for patients during 1998-2013. Log-rank tests were used to determine the OS/LCSS differences between the 1LC and 2LC in the entire surgical group(EG) and in those having an early-stage resectable tumors (ESR, tumors <4 cm, node negative). Joinpoint analysis was used to determine rates of second cancers 4-10 year after 1LC using SEER-9 during years 1985-2014. RESULTS The rate of 2LCs was significantly less than all other second cancers until 2001 when the incidence of 2LCs increased sharply and became significantly greater than all other second cancers in females starting in year 2005 and in men starting in year 2010. OS/LCSS, adjusted for propensity score by using inverse probability weighting, demonstrated similar OS, but worse LCSS for 2LCs in the EG, but similar OS/LCSSs in the ESR group. CONCLUSION Because the rate of 2LCs are increasing and because the OS/LCSS of the 1LC and 2LC are similar in early-stage lesions, we feel that continued surveillance of patients in order to find early-stage disease may be beneficial.

Abstract
OBJECTIVES To describe heart rhythm during collapse events in boxer dogs using ambulatory electrocardiogram and determine the predictive value of frequent or complex ventricular ectopy for collapse associated with ventricular tachycardia. MATERIALS AND METHODS A total of 659 ambulatory electrocardiogram recordings from 429 boxer dogs were identified from a database in the UK. Summary statistics described the frequency and complexity of ventricular ectopy during all recordings, recordings in which collapse occurred and associated boxer demographics. Positive predictive values were calculated to investigate whether frequent ventricular ectopy was useful to predict heart rhythm during episodes of collapse. RESULTS Of the 659 ambulatory electrocardiogram recordings, 250 recordings showed <50 single ventricular beats (Group 1), and frequent (≥50) or complex ventricular ectopy were observed in 409 recordings (Group 2). A total of 90 collapse events were observed in 72 ambulatory electrocardiograms from 68 dogs, comprising 30 dogs in Group 1 and 38 dogs in Group 2. In both groups, sinus rhythm was the most frequent collapse rhythm, followed by neurally mediated collapse and then ventricular tachycardia. The proportion of dogs that displayed ventricular tachycardia-associated episodic collapse given that they had frequent (≥50) or complex ventricular ectopy in the study population was 0.11 [95% confidence interval = 0.01 to 0.21]. CLINICAL SIGNIFICANCE These results challenge the preconception that UK boxer dogs with collapse will have ventricular tachycardia and, consequently, the authors recommend definitive diagnosis of the cause of episodic collapse to guide selection of therapeutic drugs.

Abstract
Abstract
Background
Noise is an important environmental risk factor. Industrial environments are rich in high-intensity infrasound (hi-IFS), which we have found to induce myocardial and coronary perivascular fibrosis in rats. Recently, a significant association between noise exposure and the incidence of atrial fibrillation (AF) was found in large cohort studies but the pathophysiology is unclear. Atrial fibrosis remains the cornerstone of atrial pathology in AF. Purpose: We hypothesized that rats exposed to hi-IFS develop atrial remodeling involving fibrosis and connexin 43, which we sought to evaluate. Material and Methods: Seventy-two Wistar rats, half exposed to hi-IFS (120dB, <20Hz) during a maximum period of 12 weeks and half age-matched controls, were studied. Atrial fibrosis was analyzed by Chromotrope-aniline blue staining. The immunohistochemical evaluation of Cx43 was performed using the polyclonal antibody connexin-43m diluted 1:1000 at 4ºC overnight. Digitized images were obtained with an optical microscope using 400× magnifications. The measurements were performed using image J software. A two-way ANOVA model was used to compare the groups. Results: The mean values of the ratio "atrial fibrosis / cardiomyocytes" increased to a maximum of 0,1095 ± 0,04 and 0,5408 ± 0,01, and of the ratio "CX43 / cardiomyocytes" decreased to 0,0834 ± 0,03 and 0,0966 ± 0,03, respectively in IFS-exposed rats and controls. IFS-exposed rats exhibited a significantly higher ratio of fibrosis (p < 0,001) and lower ratio of Cx43 (p = 0,009). Conclusion: High-intensity infrasound exposure triggers atrial remodeling in rat hearts. Whether this finding correlates to arrhythmogenic substrate in noise induced-AF is not known and reinforces the need for further experimental studies.

Abstract
Mood disorders like major depression and bipolar disorder (BD) are among the most prevalent forms of mental illness. Current knowledge of the neurobiology and pathophysiology of these disorders is still modest and clear biological markers are still missing. Thus, a better understanding of the underlying pathophysiological mechanisms to identify potential therapeutic targets is a prerequisite for the design of new drugs as well as to develop biomarkers that help in a more accurate and earlier diagnosis. Multiple pieces of evidence including genetic and neuro-imaging studies suggest that mood disorders are associated with abnormalities in endoplasmic-reticulum (ER)-related stress responses, mitochondrial function and calcium signalling. Furthermore, deregulation of the innate immune response has been described in patients diagnosed with mood disorders, including depression and BD. These disease-related events are associated with functions localized to a subdomain of the ER, known as Mitochondria-Associated Membranes (MAMs), which are lipid rafts-like domains that connect mitochondria and ER, both physically and biochemically. This review will outline the current understanding of the role of mitochondria and ER dysfunction under pathological brain conditions, particularly in major depressive disorder (MDD) and BD, that support the hypothesis that MAMs can act in these mood disorders as the link connecting ER-related stress response and mitochondrial impairment, as well as a mechanisms behind sterile inflammation arising from deregulation of innate immune responses. The role of MAMs in the pathophysiology of these pathologies and its potential relevance as a potential therapeutic target will be discussed.

Abstract
INTRODUCTION Efficacy of renin-angiotensin-aldosterone system (RAAS) blockade using angiotensin-converting enzyme inhibitors (ACEi) in dogs with preclinical myxomatous mitral valve disease (MMVD) is controversial. HYPOTHESIS Administration of spironolactone (2-4 mg q 24 h) and benazepril (0.25-0.5 mg q 24 h) in dogs with preclinical MMVD, not receiving any other cardiac medications, delays the onset of heart failure (HF) and cardiac-related death. Moreover, it reduces the progression of the disease as indicated by echocardiographic parameters and level of cardiac biomarkers N-terminal pro brain natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI). ANIMALS 184 dogs with pre-clinical MMVD and left atrium-to-aortic root ratio (LA:Ao) ≥1.6 and normalized left ventricular end-diastolic diameter (LVEDDn) ≥1.7. METHODS This is a prospective, randomized, multicenter, single-blinded, placebo-controlled study. Primary outcome variable was time-to-onset of first occurrence of HF or cardiac death. Secondary end points included effect of treatment on progression of the disease based on echocardiographic and radiographic parameters, as well as variations of NT-proBNP and cTnI concentrations. RESULTS The median time to primary end point was 902 days (95% confidence interval (CI) 682-not available) for the treatment group and 1139 days (95% CI 732-NA) for the control group (p = 0.45). Vertebral heart score (p = 0.05), LA:Ao (p < 0.001), LVEDDn (p < 0.001), trans-mitral E peak velocity (p = 0.011), and NT-proBNP (p = 0.037) were lower at the end of study in the treatment group. CONCLUSIONS This study failed in demonstrating that combined administration of spironolactone and benazepril delays onset of HF in dogs with preclinical MMVD. However, such treatment induces beneficial effects on cardiac remodeling and these results could be of clinical relevance.

Abstract
Abstract
A 36-old-man was admitted in hospital with fever and cough, fatigue, rapidly progressive exertional dyspnoea and orthopnoea. Transthoracic echocardiogram (TTE) revealed a mildly dilated left ventricle (LV) with very low ejection fraction (EF), normally sized right chambers, severe right ventricular dysfunction, moderate tricuspid regurgitation and pulmonary artery systolic pressure (PASP) of 52mmHg. The diagnosis of myocarditis was suspected, and he was transferred to the ICU in our centre to proceed the diagnostic work up. Cardiac magnetic resonance showed a severely dilated LV with an EF of 13% and a transmural fibrotic scar on the lateral wall, without signs of myocardial oedema. There was an apical thrombus. Right ventricular EF was 25%. Coronary angiography showed thrombotic occlusion of the circumflex artery with delayed filling of marginal branches. Endomyocardial biopsy was performed but no myocardial lesion was seen. Temporary inotropic support was needed for low cardiac output. Optimized therapy for heart failure and anticoagulation were given and he received an implantable cardioverter defibrillator before discharge in NHYA class II. Two months later, he was re-admitted in his local hospital, complaining of cough with sputum, fever and shortness of breath. He was hypotensive, tachycardic and cyanotic. Blood workup revealed renal failure, coagulopathy and liver dysfunction with C-reactive protein of 10 mg/dL, but no leucocytosis. NT pro-BNP was 2459 pg/mL. Empirical antibiotics and inotropes were started. TTE revealed an EF of 10-15%, moderate functional mitral regurgitation, right ventricular dysfunction, moderate tricuspid regurgitation, and a PASP of 50 mmHg. He was transferred back to our centre. On admission, he was hemodynamically stable with perfusions of dobutamine and noradrenaline. Work up for inclusion in heart transplant waiting list was initiated. However, he deteriorated rapidly. It was decided to implant a biventricular assist device (BiVAD) for circulatory support as bridge to transplant. A short/medium term assist device was chosen as it was expected that a donor would be found in less than a month, and if this was not the case, it could be upgraded to a medium/long term device. Cannulas for LVAD were introduced on the LV apex and ascending aorta and for RVAD in the femoral vein and pulmonary artery. Good flows were achieved on both devices and there were no complications in the immediate post-operative period. He was extubated and weaned off inotropes on day 2. On day 9, a heart donor was found, and he was transplanted. No complications occurred in the post-operative period. He was discharged home on day 24, and resumed an active life.
This case illustrates the usefulness of temporary devices to bridge critically ill candidates to heart transplantation. Also, it emphasizes the importance of identifying patients who definitely need a BiVAD when end-stage heart failure involves both ventricles.

Abstract
Abstract
Introduction and aim
Infective endocarditis (IE) is a complex and heterogeneous disease which might lead to cardiac surgery. For such cases, several perioperative risk predictive tools have emerged. We aimed to validate the recently developed PALSUSE, STS risk score for IE and modified AEPEI score and to compare their performances with the established EuroSCORE II.
Methods
We retrospectively accessed 128 patients from a single center registry who underwent heart surgery for active infective endocarditis between January 2007 and November 2014. Discrimination and calibration of models were assessed by receiver operating characteristic curve analysis and Hosmer-Lemeshow test.
Results
Perioperative mortality was 16.4% (n=21). The median EuroSCORE II, PALSUSE, STS risk score for IE and modified AEPEI score were 6.6% [IQR 3.5–18.2], 5 [IQR 3–7], 25 [IQR 16–32] and 1 [IQR 0–1.8], respectively. Discriminative power was numerically higher for EuroSCORE II (AUC of 0.83, 95% CI, 0.75–0.91) followed by STS risk score for IE (AUC of 0.75, 95% CI 0.64–0.86), PALSUSE (AUC of 0.74, 95% CI 0.64–0.86) and modified AEPEI (AUC of 0.68, 95% CI 0.57–0.788) – figure 1. The Hosmer-Lemeshow test showed good calibration for EuroSCORE II (p=0.08) and STS risk score for IE (p=0.03) but not for PALSUSE (p=0.65), modified AEPEI (p=0.12).
Figure 1
Conclusion
All scores adequately stratified peri-operative risk in active infective endocarditis, however EuroSCORE II in the overall comparison performed better in this population. Heterogeneity of performance of risk scores in different cohorts of infective endocarditis highlights the complexity of this disease.

Abstract
The deep peribiliary glands (DPBG) are a niche of progenitor cells in the wall of the biliary duct (BD) and are the second line of multiplication when severe lesion of the epithelium occurs. Previous studies have identified DPBG injury as a cause of post-liver transplant (LT) biliary stenosis; this complication is a major cause of post-LT morbidity. The incidence of biliary stenosis in our center is high (38.1%). This study evaluates the lesion of DPBG in response to ischemia. Graft BD was collected in adult LT between August 2016-July 2017, from donation after brain death. Samples of 45 grafts were collected at 2 moments: BD1-during graft preparation and BD2-before biliary anastomosis. Histological analysis of the samples was performed and then classified according to degree of lesion (0, ≤50%, and >50%). A comparison was made between the degree of lesion and graft ischemia, graft histology, donor, and procurement variables. The DPBG lesion was more frequent in BD2 (20.9% vs 7%, P = .079). BD2 lesions with DPBG lesions had higher medians and means at all times of ischemia. The difference was greater in the warm ischemia time (0: 43.3 ± 12.53 minutes vs ≤50%: 52.4 ± 14.38 minutes, P = .068). The group of BD1 with DPBG lesion presented superior median cold ischemia time (CIT). In the analysis of the remaining variables there were also no statistically significant differences. We concluded that during the period of CIT there is already lesion of the DPBG, which increases after reperfusion of the graft, in greater association with longer warm ischemia time.

Abstract
Accurate characterization of laser pulses used in experiments is a crucial step to the analysis of their results. In this paper, a novel single-shot frequency-resolved optical gating (FROG) device is described, one that incorporates a dispersive element which allows it to fully characterize pulses up to 25 ps in duration with a 65 fs per pixel temporal resolution. A newly developed phase retrieval routine based on memetic algorithms is implemented and shown to circumvent the stagnation problem that often occurs with traditional FROG analysis programs when they encounter a local minimum.

Abstract
INTRODUCTION Six-minute walk test (6MWT) is used for evaluating functional exercise capacity. To the best of our knowledge, there are no reference equations to predict six-minute walk distance (6MWD) for the Portuguese population. The aims of the present study were to measure anthropometric data and 6MWD in a sample of healthy Portuguese population, to establish reference equations to predict 6MWD and to compare our equations with those obtained by previously published studies. METHODS We conducted an observational prospective study. We consecutively recruited 158 healthy 18-70 years old subjects from Porto district, who performed two 6MWTs using a standardized protocol. The best 6MWD was used for further analysis. RESULTS The mean 6MWD was 627.8m (SD=73.3m). The variables that were significantly associated with the 6MWD were age, sex, BMI and ΔHR (Heart Rateat the end of the test-HRat rest). We found three explanatory models for 6MWD, the best with an explanatory power of 38%: 6MWD=721.7-1.6×Age-4.0×BMI+0.9×ΔHR+58.4×Sex. We verified that 6MWD decreased 1.6m per year of age, and 4.0m per unit of BMI and increased 0.892m per beat per minute. Moreover, on average, males walk 58.4m more than females (p<0.001). Applying equations from other studies to our population resulted in an overestimation or underestimation of the 6MWD. CONCLUSION The present study was the first to describe the 6MWD in healthy Portuguese people aged 18-70 years old and to propose predictive equations. These can contribute to improving the evaluation of Caucasian Mediterranean patients with diseases that affect their functional capacity.

Abstract
The aim of this work was to investigate associations between individual cow Mycobacterium avium ssp. paratuberculosis (MAP) seropositivity, 305-d corrected milk production, and somatic cell count during 5 lactations lifespan in Portuguese dairy herds using multilevel mixed models. We used MAP serum ELISA (Idexx MAP Ac, Idexx Laboratories Inc., Westbrook, ME) results (n = 23,960) from all the 20,221 adult cows present in 329 farms and corresponding 47,586 lactation records from the National Dairy Improvement Association. Cows and farms were classified as positive or negative. Multilevel mixed models were used to investigate the association of cow MAP status with variation in milk production and somatic cell count. Cow MAP status, farm status, and lactation number were considered as independent variables. A quadratic function of lactation number was used to mimic the effect of lactation order on milk production. The models considered 3 levels: measurement occasion (level 1) within cow (level 2) and cow within farm (level 3). Four final models were produced, including all herds and cows, to address the effect of farm status (models 1 and 2) or the effect of cow status (models 3 and 4) on the outcome variables. Our results show that MAP status affects milk production. Losses are detectable from third lactation onward. During the first 5 lactations, positive cows accumulated an average loss of 1,284.8 kg of milk when compared with the negative cows. We also observed that somatic cell counts were higher in positive cows and a positive interaction occurs between cow status and lactation number, suggesting a positive association between MAP infection and increased somatic cell counts. Our results are in line with previous studies, suggesting a possible positive relation between cow milk production and susceptibility to MAP infection.

Abstract
INTRODUCTION Erectile dysfunction (ED) is the inability to achieve or maintain an erection for satisfactory sexual activity. Recent studies have shown an association between ED and chronic obstructive pulmonary disease (COPD). However, this issue is often ignored. We aimed to evaluate the ED prevalence in COPD patients and its risk factors and to study the impact of dyspnea in sexual activity. METHODS Cross-sectional study that included sexually active male patients with COPD. The International Index of Erectile Function (IIEF-5) questionnaire evaluated ED and the Respiratory Experiences with Sexuality Profile (RESP) was used to evaluate the impact of dyspnea on sexual activity. Risk factors for mild-moderate or moderate ED were determined using logistic regression. RESULTS 84 patients were consecutively assessed for eligibility, 67 were included (median age: 65 years, 13% never-smokers). Twenty two percent had COPD 2011-GOLD A; 22% GOLD B, 14% GOLD C and 42% GOLD D. Fifty-eight patients (87%) had some degree of ED: 26 (45%) mild, 20 (34%) mild-moderate and 12 (21%) moderate ED. ED occurred in all GOLD stages of COPD, mainly in GOLD B and D stages. Higher CAT score was independently associated to mild-moderate/moderate ED. Most patients (85%) reported dyspnea during their sexual activity but 72% had never talked about it with their physician. CONCLUSIONS ED is highly prevalent among COPD patients and it is more severe in patients with higher CAT scores. Dyspnea affects their sexual activity but this is not a topic often discussed between patients and doctors, something which needs to be improved.

Abstract
Biological invasions are a major threat to the world's biota and are considered a major cause of biodiversity loss. Therefore, world marine policy has recognized the need for more marine protected areas (MPAs) as a major tool for biodiversity conservation. The present work experimentally evaluated how protected communities from an offshore island can face the settlement and/or expansion of nonindigenous species (NIS). First, NIS colonization success in marine protected and marina communities was compared by deploying PVC settling plates at the Garajau MPA and Funchal marina (SW Madeira Island). Then, the settling plates from the MPA were transferred to Funchal marina to test their resistance to NIS invasion under high levels of NIS pressure. Results indicated that the structure and composition of fouling communities from the MPA differed from those collected in the marina. Interestingly, communities from the protected area showed lower NIS colonization success, suggesting some degree of biotic resistance against NIS invasion.

Abstract
IntroductionPsychopathology rating scales have been widely used. Studies evaluating the congruence between self and observer-reported ratings show inconsistent results.Objectives or aimsDetermine whether there was consistency between psychopathology as assessed by patients and clinicians’ assessment in outpatients observed in the Young Adult Unit of our Psychiatry Department (Coimbra Hospital and University Centre-Portugal).MethodsSocio-demographic characterization was undertaken with young adult outpatients observed during nineteen months (1st January 2015–31st July 2016). Brief Symptom Inventory–53 items (BSI-53) and Brief Psychiatric Rating Scale (BPRS) were applied at the first clinical evaluation. Spearman correlation coefficient between General Severity Index (GSI) of BSI-53 and BPRS total score was calculated.ResultsDuring the mentioned interval 255 outpatients were observed: 64.3% females and 35.7% males; aged between 17 and 39 years old (average: 20.56; median: 20). Fifty percent were diagnosed with neurotic, stress-related and somatoform disorders (ICD-10 F40-48) and 14.1% with mood disorders (ICD-10 F30-39). BPRS and BSI-53 rating scales were administered to 55 patients: 72.5% females and 27.5% males; average age 21.2. A statistical significant correlation was found between BPRS total and GSI score.ConclusionsSeveral factors can determine the accuracy of psychopathology self-assessment, including diagnosis and severity of illness. In fact, studies show strong correlation between self and observer assessment of depressive and anxious psychopathology, but no correlation in psychotic psychopathological dimensions. Therefore, the correlation found in this population can be explained by the fact that the majority of patients were diagnosed with neurotic, stress-related and somatoform and mood disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionMost mental disorders begin during adolescence and early adulthood (18–24-years-old), highlighting the importance of understanding the onset and progression of mental disorders among youths. Although progress has been made, namely by creating youth mental health transition services, gaps continue to exist. Locally, our recently constituted young adults unit aimed to minimize discontinuities in care.Objectives/aimsTo characterize a population of young adult psychiatric outpatients, regarding socio-demographic and clinic variables.MethodsSocio-demographic and clinic characterization of young adult psychiatric outpatients observed during 1st January 2015–30th July 2016.ResultsTwo hundred and fifty-five outpatients were observed: 64.3% females and 35.7% males, average age 20.56-years-old (median 20). Most lived in urban areas (59.4%), with their parents (27.8%), were students (80.4%), attending secondary school (36.1%). A total of, 27.5% were referenced by an emergency department, and adjustment disorders (ICD-10 F43.2) were the most frequent diagnosis (21.6%). Regarding suicidal behaviours and self-harm, 9.8% did self-cutting. A vast majority did not have previous psychiatric hospitalizations–only 5.9% outpatients had at least one. In total, 39.8% were medicated with antidepressants (1/3 of which in association with other drugs), and about 38.8% received cognitive-behavioural interventions. About 2/3 of patients (66.3%) remained in care and only about 1/6 (15.7%) were discharged.ConclusionsOur typical youth psychiatric outpatient was of female gender, student, living with its parents. Adjustment disorders were the most frequent diagnosis, and antidepressants were the main psychopharmacologic option, often combined with other psychotropic drugs. In the future, psychotherapy interventions should be more widely available, namely group psychotherapy.Disclosure of interestThe authors have not supplied their declaration of competing interest.
