Abstract
INTRODUCTION Portugal currently hosts 24 active radiotherapy departments, 8 public and 16 privates, presenting potential radiation exposure risks to multidisciplinary teams. Patients in these treatments also face ionising radiation during treatment planning and verification. METHODS Authorisation and ethical approval were secured for a national online survey, disseminated to radiotherapy departments across Portugal. The survey encompassed three sections: equipment, staff, and radiographer role characterisation; occupational exposure values for one month; and exposure parameters, including computed tomography (CT) dose values [CT dose index (CTDIvol) and dose length product (DLP)] for breast and prostate cancer CT planning. Local Diagnostic Reference Levels (DRLs) derived were based on the 75th percentile of median dose values. RESULTS The study garnered a 50% response rate from public institutions, 12,5% from private and 25% from all active radiotherapy institutions in Portugal. All departments employ Three-Dimensional Conformal Radiation Therapy (3D-CRT) and incorporate Intensity Modulated Radiation Therapy (IMRT) and/or Volumetric Modulated Arc Therapy (VMAT) irradiation techniques. Additionally, half of the departments also perform Brachytherapy (BT). Radiographers demonstrated an occupational dose of zero mSv. CT planning dose values were 13 mGy and 512 mGy cm for breast CT and 16 mGy and 689 mGy cm for prostate CT, pertaining to CTDIvol and DLP, respectively. CONCLUSION Most aspects of national radiotherapy characterisation align with the established literature. Occupational exposure values exhibited consistency across radiotherapy modalities. An approach to national DRLs was formulated for breast and prostate CT planning, yielding values congruent with recent European studies. IMPLICATIONS FOR PRACTICE This study offers vital insights for analysing occupational contexts and risk prevention, serving as the initial characterisation of the national radiotherapy landscape. It also pioneers the calculation of DRLs for CT planning in radiotherapy to optimise procedures.

Abstract
INTRODUCTION Dolutegravir/rilpivirine (DTG/RPV) is an effective antiretroviral (ART) regimen endorsed by clinical trials as a switch therapy. The aim of our study was to analyse the efficacy and safety of DTG/RPV in real-world clinical practice. METHODS Observational, multicentre study of patients who started DTG/RPV. Efficacy, adverse events and metabolic changes at 48 weeks were analysed. RESULTS A total of 348 patients were included; median time of HIV infection was 21.1 years, 33.7% were AIDS cases; median nadir CD4 was 160 cells/μL; 90.5% had received ≥3 lines of ART and 179 (53.8%) had prior virological failure. Convenience (43.5%), toxicity/intolerance (28.4%) and interactions (17.0%) were the main reasons for starting DTG/RPV. Previous regimens were protease inhibitors (PI) (31.6%), non-nucleoside reverse transcriptase inhibitors (NNRTI) (20.4%) and integrase strand transfer inhibitors (INSTI) (14.9%). Efficacy (HIV-RNA <50 copies/mL) at 48 weeks was 89.7% (95% CI 86.1-92.6) by intention-to-treat (ITT) and 94.2% (95% CI 91.3-96.4) by on treatment (OT); 10 patients (3.1%) were not suppressed (3 had abandoned ART). There was a mean decrease in triglycerides, total cholesterol, low-density lipoprotein-cholesterol, glutamic-pyruvic transaminase (GPT), gamma-glutamyl transferase (GGT) and alkaline phosphatase; creatinine increased with a decrease in glomerular filtration rate. CONCLUSIONS This study confirms the effectiveness, tolerability and safety of DTG/RPV in real-world clinical practice in a different population from clinical trials, with many years of infection, low CD4 nadir, several previous treatment lines, more than half with virological failures, and one-third diagnosed with AIDS. The switch to DTG/RPV was safe with few discontinuations due to adverse effects. Modifications of the lipid and liver profiles were favourable. There were no relevant changes in kidney function.

Abstract
Plasma Position Reflectometry (PPR) is planned to provide plasma position and shape information for plasma operation in future fusion reactors. Its primary function is to calibrate the drift of the magnetic signals due to the integral nature of magnetic measurement. Here, we attempt to measure plasma position using ordinary mode (O-mode) and extraordinary mode (X-mode) reflectometry systems on two tokamaks. A new physical model based on the phase shift is proposed to deduce the relative movement of the cut-off layer without density inversion. We demonstrate the plasma position measurements by absolute measurement from density profile inversion and relative measurement from phase shift. The combination of X-mode and O-mode reflectometers can minimize the limitations of single polarization reflectometry and further increase the accuracy of plasma position measurement. These results could provide an important technical basis for the further development of a real-time control system based on PPR.

Abstract
New cement-based materials such as alkali-activated binders (AABs) or geopolymers allow the incorporation of waste or industrial by-products in their formulation, resulting an interesting valorization technique. Therefore, it is essential to inquire about the potential environmental and health impacts throughout their life cycle. In the European context, a minimum aquatic toxicity tests battery has been recommended for construction products, but their potential biological effects on marine ecosystems have not been considered. In this study, three industrial by-products, PAVAL® (PV) aluminum oxide, weathered bottom ash (WBA) resulting from incinerator bottom ash and glass cullet recycling waste (CSP), were evaluated as precursors in the AAB formulation from an environmental point of view. To determine the potential effects on marine environment caused by the leaching of contaminants from these materials into seawater, the leaching test EN-12457-2 and an ecotoxicity test using the model organism sea urchin Paracentrotus lividus were conducted. The percentage of abnormal larval development was selected as endpoint of the toxicity test. Based on the results obtained from the toxicity tests, AABs have less damaging impact (EC50 values: 49.2%-51.9%) on the marine environment in general than raw materials. The results highlight the need to stablish a specific battery of toxicity tests for the environmental assessment of construction products on marine ecosystem.

Abstract
INTRODUCTION This study aimed to characterise radiation protection (RP) measures used in interventional radiology (IR) departments in Portugal with respect to European and national recommendations. METHODS An online national survey was created to characterise the fluoroscopy technology as well as analyse the frequency of body fluoroscopy-guided intervention procedures (FGIP), RP education and training of the staff, and RP measures used daily. RESULTS In Portugal, most equipment for FGIP are single-sourced and have a flat panel detector (70%). The most commonly FGIP are percutaneous biliary drainage, percutaneous arterial and venous thrombolysis/thrombectomy, arteriovenous malformations embolization, and percutaneous transluminal balloon angioplasty for arteriovenous fistulas. Only a few staff members had received postgraduate education and training in RP (30%), with most nurses having not received RP education and training (40%). Some of the recommended RP measures lacked harmonisation. Additionally, >50% of the IR departments do not consider examination dose values to identify patients eligible for tissue reactions follow-up. CONCLUSION This is the first study to examine the characteristics of IR departments in Portugal. We observed a lack of RP education and training among staff members; further, there was a need to update some RP measures in some IR departments according to the recommendations. IMPLICATIONS FOR PRACTICE Our findings will be presented to the participating IR departments in order to update and promote RP best practices. Moreover, our findings will be presented to the national societies of the different professional groups in order to inform strategies for harmonising RP education and training of the staff.

Abstract
Futsal is a sports game that features high intensity movements with change of speed or direction, present in several actions during the game. With this study is intended to analyse, compare and evaluate the predictive factor of leg power on shooting speed and fatigue levels in young futsal athletes in order to establish effort patterns in these ages, to prescribe training sessions adequately in terms of external/internal load. The study had 32 participants, male, aged between 12 and 17 years (Mean = 14.56}1.66). Participants were evaluated in relation to their lower limb power through the Chronojump system, the speed was measured through a radar placed on the goal line, and in relation to their fatigue levels through the Running Anaerobic Sprint Test (RAST). To identify the differences between groups, the tests of Kruskal Wallis and Mann Whitney were used, and also a simple linear regression tests for predictive values between variables. In relation to the shots speed, higher values were found in the older groups (P≤0.001), which is directly and significantly related to the higher values of lower limb power, also verified in the older athletes (P≤0.001). In relation to the fatigue levels, it increases as the age of the athletes is higher, verifying that the power of the lower limbs is a predictor variable of the fatigue index (P≤0.001). The analysis conducted indicate that there are significant differences in the association between shooting speed, lower limb power and fatigue indices according to the players levels studied.

Abstract
Approaches to identify novel druggable targets for treating neglected diseases include computational studies that predict possible interactions of drugs and their molecular targets. Hypoxanthine phosphoribosyltransferase (HPRT) plays a central role in the purine salvage pathway. This enzyme is essential for the survival of the protozoan parasite T. cruzi, the causal agent of Chagas disease, and other parasites related to neglected diseases. Here we found dissimilar functional behaviours between TcHPRT and the human homologue, HsHPRT, in the presence of substrate analogues that can lie in differences in their oligomeric assemblies and structural features. To shed light on this issue, we carried out a comparative structural analysis between both enzymes. Our results show that HsHPRT is considerably more resistant to controlled proteolysis than TcHPRT. Moreover, we observed a variation in the length of two key loops depending on the structural arrangement of each protein (groups D1T1 and D1T1'). Such variations might be involved in inter-subunit communication or influencing the oligomeric state. Besides, to understand the molecular basis that govern D1T1 and D1T1' folding groups, we explored the distribution of charges on the interaction surfaces of TcHPRT and HsHPRT, respectively. To know whether the rigidity degree bears effect on the active site, we studied the flexibility of both proteins. The analysis performed here illuminates the underlying reasons and significance behind each protein's preference for one or the other quaternary arrangement that can be exploited for therapeutic approaches.

Abstract
Abstract
Background
Complete heart block is considered a unique and rare complication of Takotsubo cardiomyopathy, an otherwise self-resolving disease. When this occurs, there is a double clinical dilemma: first to find out which triggered the other and second, to decide whether or not to implant a permanent pacemaker.
Case presentation
We present a case of a 77 years-old female patient, with previous medical history of arterial hypertension, diabetes mellitus, dyslipidemia and bifascicular block known since 2013. She came to the emergency department after recurrent syncopal episodes. At admission a complete heart block was diagnosed, and it was implanted a single chamber temporary pacemaker. The patient remained in disproportional acute decompensated heart failure despite pacemaker implantation. She denied chest pain although referring an episode of self-limiting chest pain 2 days before, after an argument with the family. Blood analysis showed an important rise in NTproBNP and troponin levels. Transthoracic echocardiogram showed a dilated left ventricle with akinesia of apical and mid segments, hyperkinesia of basal segments and severely depressed left ventricle ejection fraction. Coronary angiography showed no significant lesions and the diagnosis of Takotsubo cardiomyopathy was suspected. During the following days, she recovered her own intrinsic rhythm. Electrocardiogram evolved with deep T-wave inversion and prolonged QT interval and transthoracic echocardiogram showed resolution of the previous alterations. Despite complete reversion of rhythm alteration, it was decided to implant a permanent pacemaker.
Conclusions
We describe a rare, life-threatening and often underdiagnosed complication of the stress cardiomyopathy. Furthermore, we performed a literature revision of this rare complication and discussed the therapeutic challenge encountered in such patients.

Abstract
COVID-19 pandemic response was an opportunity to advocate for HiAP as everyone developed opinions on how policies could affect the different dimensions, including health and economy. Health planning, from the local to the international level, is the main setting where we still need to advocate for the inclusion of all political sectors and actors in order to ensure an effective HiAP implementation. From a more technical perspective, there is still a lot to do when it comes to implementing and improving economic evaluations, including on data on costs, valuing benefits or using cost-effectiveness approaches.

Abstract
Introduction
Patients hospitalized due to heart failure (HF) compose a heterogeneous population whose prognosis is difficult to forecast. Frailty is a well-recognized prognostic marker in multiple chronic diseases, including HF; however, frailty evaluation is often subjective and standardized and objective prediction models are lacking. We aimed to evaluate if an objective and simple index – Heart Failure Frailty Index (HFFI)– can predict long-term outcomes in this population.
Methods
A retrospective analysis of 258 patients admitted to a Cardiology ward due to HF was performed. The variables albumin, C-reactive protein levels, age and body mass index (BMI) were selected for frailty assessment. After attributing points for each variable, according to odds ratio on univariate analysis, the HFFI was calculated (range 0–8), resulting from the sum of the points attributed to each variable. Kaplan-Meyer and Cox-regression analysis were performed to evaluate HFFI association with 24-month mortality (24MM) and 24-month composite endpoint of rehospitalization or death (24MH).
Results
Mean patient age was 75 (±11) years; 51% were men. 45.7% had atrial fibrillation, 15.9% hat history of acute myocardial infarction, 67.8% had hypertension. Mean LVEF was 47% (±17). A LVEF <40% was present in 40% of patients. 24MM was 11.5% and 24 MH was 58%. Patients were considered frail if they had an HFFI ≥3. Kaplan-Meyer curve analysis revealed a significantly lower median time to 24MM in frail patients, as assessed by HFFI, comparing to non-frail patients (585±33 days vs 697±12 days, mortality rate: 25.4% vs 5.7%, χ2=18.156, p<0.001). There was also a significantly lower median time to 24MH in frail patients (336±34 days vs 449±24 days, combined endpoint rate: 76.1% vs 50.3%, χ2=10.884, p=0.001). Cox regression analysis demonstrated that HFFI independently predicts 24MM (HR: 1.364, p=0.002) and 24MH (HR: 1.106, p=0.035), even after adjustment for other prognostic markers, such as history of atrial fibrillation, previous myocardial infarction, diabetes and natriuretic peptides serum level at index event.
Conclusion
HFFI is a simple and objective frailty index correlated with 24MM and 24MH, being an independent prognostic marker in this population. Its use may help to identify patients with a high risk of mortality or readmission, in need of specialized care.

Abstract
Abstract
Introduction
The patients with Pulmonary Thromboembolism (PE) stratified as intermediate-high risk with the European Society of Cardiology classification represent an heterogenous population, with the majority having a benign outcome however some evolving in clinical deterioration. Several risk scores have been developed to try and refine the population most at risk but they are deemed sub-optimal.
Purpose
Our aim was to assess the capacity of the National Early Warning Score (NEWS) in predicting a composite end-point of 30-days cardiovascular mortality, rescue thombolysis and/or haemodynamic instability, in a population of intermediate-high risk PE, as compared with other risk evaluation scores as the PESI and SHIeLD scores.
Methods
We performed a retrospective analysis between 2014 and 2019 of all patients admitted for intermediate-high risk PE, in a single expert centre. The patients who underwent fibrinolysis as per clinician discretion (without haemodynamically instability or clinical evidence of clinical deterioration) were excluded. Medical records were analysed for clinical data and outcomes. The predictive accuracy of all scores were assessed using the area under curve (AUC) of receiver operating characteristics (ROC) curve. The association between NEWS and composite end-point at 30-days was analyzed using a Cox regression model.
Results
Of the 1132 patients assessed and admitted with PE, 116 patients fulfilled all inclusion criteria and none of the exclusion criteria and were analysed. The mean age was 69±16 years at time of diagnosis with a female preponderance (62.9%). Most patients were treated with anticoagulation (97.4%), 68% with low molecular weight heparin and the remaining with unfractionated heparin. The average NEWS score was 7±3, the average PESI score was 110±34 and the average SHIeLD score was 14±13. A primary composite end-point occurred in 18 patients (15.5%). The NEWS score showed the greatest predictive power for the occurrence of an event (OR 1.35; 95% CI 1.11–1.64, p=0.003) compared with the SHIeLD score (OR 1.0; 95% CI 1.00–1.07, p=0.035) and the PESI score (OR 1.02; 95% CI 1.00–1.03, p=0.03); it also showed a greatest discriminative capacity with the ROC curve analysis (Figure 1A) demonstrating an AUC of 0.70, vs 0.65 and 0.62 respectively. The survival analysis demonstrated a Hazard Ratio of 1.29 (95% CI 1.10–1.52; p=0.002) signifying a 29% increased risk of an event per each NEWS class increase, with the Kaplan Meier curves widening significantly in the different terciles of the score (Figure 1B).
Conclusions
In PE patients with intermediate-high risk the NEWS score demonstrated a greater predictive power and discriminative capacity than other commonly used risk scores. The NEWS score may help to identify patients in this risk category who might benefit from a reperfusion strategy, but larger studies are needed to confirm this hypothesis.

Percutaneous coronary intervention in elderly patients with chronic kidney disease and non-ST segment elevation acute coronary syndrome – is it worth it? Eur Heart J 2022. [DOI: 10.1093/eurheartj/ehac544.1252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
Abstract
ESC guidelines recommend revascularization in patients (pts) with chronic kidney disease (CKD) irrespective of age. However, elderly pts are usually underrepresented in the available data on percutaneous coronary intervention (PCI). Thus, the decision on whether to perform PCI in these pts is usually at the discretion of the cardiology team.
Aim
To evaluate the impact of PCI vs conservative approach (CA) in elderly pts (>80 years) with CKD and unstable angina (UA)/non-ST segment elevation myocardial infarction (NSTEMI) who were enrolled in the Portuguese National Registry of Acute Coronary Syndromes. To determine impact of CKD in in-hospital (IH) and long-term outcomes, including MACE (myocardial infarction, stroke and death) and death at 1 year.
Study population
Elderly pts admitted with UA and NSTEMI, from 2010 until 2021. There were three different groups: Group 1 – eGFR ≥60 ml/min/1.73 m2; Group 2 – eGFR between 30 and 59 ml/min/1.73 m2 and Group 3 – eGFR <30 ml/min/1.73 m2. Pts with ST-segment elevation myocardial infarction and cardiogenic shock were excluded.
Results
A total of 2443 pts, of which 921 (37,7%) were submitted to PCI. 50,2% (n=1126,) were from the group 1, 38,5% (n=941) from group 2 and 11.3% (n=276) from group 3.
Regarding overall population, pts submitted to PCI were mainly male (60,4%) with a mean age of 84±3 years old. They had previous history of PCI (21,6% vs 15,1% p<0.001), less history of heart failure (HF), stroke or dementia (8,5% vs 16,5%; 8,1 vs 13.3% and 2,1 vs 5,9%, p<0.001). At presentation they had more angina (88,8% vs 81,2% p<0.001), less NT-proBNP levels (387 vs 561 p<0.001) and were more frequently in KK class I (75,6% vs 70,2% p=0.004). They developed less HF (21% vs 27%, p<0.001) and MACE (5,7% vs 9,1% p=0.003). Pts in the group 3 were less submitted to PCI (27,5% vs 38,2% vs 39,6% p<0.001) and had more MACE and cardiovascular death when comparing to group 2 and 1 (16,1% vs 8,7% vs 5,3% and 10,5% vs 5,5% vs 2,6% p<0.001 respectively).
Comparing PCI vs CA in each group, there was no difference in IH outcomes between both strategies in group 3. The same was not true for groups 1 and 2, in which PCI seemed to favor overall outcomes (p=0.001 and p=0.015 respectively).
The predictors of IH death and MACE were: age (OR 1.068 p=0.010), dementia (OR 2,376 p=0.015), KK class >1 (OR 2,243, p<0.001), atrial fibrilhation (OR 1.605, p=0.046), not having PCI (OR 0.309, p<0.001), eGFR <30 (OR 3.51, p<0.001) and PCI in pts with eGFR <30 (OR 2.923, p=0.019).
Interestingly, survival analysis showed that pts submitted to PCI in all 3 groups (including group 3) had a longer 1-year survival (p<0.001, p<0.001 and p<0.004).
Conclusions
PCI performance in elderly pts with CKD should be individualized. In our population, especially in group 3, the performance of PCI is associated with a higher IH mortality, however, after surviving hospitalization, these pts seem to have a benefit in 1 year survival.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
Purpose: Examine the impact of parental mental health history on patient and patent-reported post-concussion symptoms of anxiety. Methods: Participants included 105 adolescents (42.9% male), 12–18 years old, including concussion patients (n = 72, 3.42 ± 1.7 days post-injury) and age-and-sex matched controls (n = 33). Patients and parents completed the Screen for Child Anxiety Disorders, Parent and Child versions (SCARED-P, SCARED-C) and medical histories. T-tests were used to compare control/concussed responses on the SCARED. Logistic regression (LR) was used to evaluate group predictors, as well as high/low (i.e., >21 PCSS total score) concussion symptom groups at 30 days post-injury. Results: Results indicated that concussed SCARED-C (controls: M = 7.88 SD = 7.55, concussed: M = 13.4 SD = 11.42), (t[103] = −2.53, p = 0.01) and SCARED-P (controls: M = 3.55 SD = 3.62, concussed: M = 6.72 SD = 7.12), (t[103] = −2.42, p < 0.01) scores were higher than controls. SCARED-C/SCARED-P scores were not predictive of high/low symptom report at 30 days post-injury, X2(2, n = 59) = 3.46, p = 0.18. The stepwise LR model was significant, X2(1, n = 105) = 7.34, p = 0.007; SCARED-C scores were predictive of concussion group inclusion, SCARED-P scores were not. In analyses of only patients whose parent reported a mental health history (22/105, 21%), there was no significant difference between control and patients on the SCARED-C, t(20) = −1.82, p = 0.08, or SCARED-P, t(20) = −0.34, p = 0.74. SCARED-C/SCARED-P scores did not predict control/concussion group inclusion, X2(2, n = 22) = 5.04, p = 0.08. Conclusions: SCARED-P/SCARED-C scores effectively differentiated between groups: patients and parents reported higher anxiety symptoms. The inclusion of parents with mental health diagnoses precluded the SCARED from differentiating controls from patients.

Abstract
Study question
What are the factors associated with clinical pregnancy in the first single embryo transfer of an oocyte donation treatment?
Summary answer
The number of blastocysts and the use of donor sperm were positively correlated with clinical pregnancy, while the use of vitrified/warmed oocytes was negatively correlated.
What is known already
The use of donor oocytes for in vitro fertilization treatments is often necessary to overcome infertility. The number of donor oocytes allocated to each recipient is a key variable to the cumulative success of these treatments. However, time to pregnancy is another key metric in assisted reproduction, and it is important to achieve a better understanding of the factors influencing the success of the first embryo transfer of an oocyte donation treatment.
Study design, size, duration
A retrospective study was conducted to analyze the outcome of the first single blastocyst transfer of 1665 oocyte donation cycles, from 8 private IVF units, from July 2018 to July 2021. Patients who underwent multiple cycles were only included in the study once, during their first treatment. The endpoint of the study was the clinical pregnancy rate, defined by the presence of a gestational sac confirmed by ultrasound one month after the transfer.
Participants/materials, setting, methods
All cycles during the study period, using donor oocytes, resulting in a first fresh or frozen single blastocyst transfer were analyzed. Cases that used PGT-A or sperm from testicular biopsy were excluded. Multiple logistic regression was used to determine the association of the variables: patient age, sperm origin, vitrified/warmed oocytes, fertilization and blastocyst development rate, total number of usable blastocysts obtained, fresh/frozen transfer, and embryonic day at transfer.
Main results and the role of chance
A total of 972 (58.4%) embryo transfers resulted in a clinical pregnancy in the study population. The mean age of the recipient and male partner was 42±4.4 years and 42.1±6.0 years, respectively, and did not differ between positive and negative transfer groups. Statistically significant higher pregnancy rates were observed for day 5 transfers vs. day 6 (59% vs 46%) and fresh vs. vitrified/thawed oocytes (64% vs. 55%). The mean number of zygotes (5.1 vs. 4.8, p = 0.032), the mean fertilization rate (76.3% vs. 72.8%, p = 0.007), the mean usable blastocyst development rate (60.0% vs. 57.7%, p = 0.006) and the mean total number of usable blastocysts (2.9 vs. 2.6, p < 0.001) were higher in clinical pregnancy group.
The results of multiple logistic regression showed that the use of sperm donor increased the chances of achieving a clinical pregnancy rate in the first embryo transfer (OR 1.36, 1.04-1.79), and the use of vitrified/thawed oocytes reduced them (OR 0.69, 0.56-0.85). There was a positive association with a higher number of usable blastocysts obtained in a cycle, and higher pregnancy rates (OR 1.16, 1.07-1.26), presumably by allowing for additional morphological embryo selection.
Limitations, reasons for caution
Certain confounding factors were not accounted for: variability of results between the different IVF units, endometrial preparation protocols, post-warming embryo morphology, sperm analysis diagnostic, as well as variability in recipients’ and donors’ baseline characteristics.
Wider implications of the findings
Factors of an oocyte donation treatment influencing the outcome of the first embryo transfer were identified. A better understanding of these factors, and interactions amongst them, is key to maximize the efficacy of these treatments, and achieve an optimal use of a limited resource such as donated oocytes.

Abstract
Background The existing digital healthcare solutions demand a service development approach that assesses needs, experience, and outcomes, to develop high-value digital healthcare services. The objective of this study was to develop a digital transformation of the patients’ follow-up service after cardiac surgery, based on a remote patient monitoring service that would respond to the real context challenges. Methods The study followed the Design Science Research methodology framework and incorporated concepts from the Lean startup method to start designing a minimal viable product (MVP) from the available resources. The service was implemented in a pilot study with 29 patients in 4 iterative develop-test-learn cycles, with the engagement of developers, researchers, clinical teams, and patients. Results Patients reported outcomes daily for 30 days after surgery through Internet-of-Things (IoT) devices and a mobile app. The service’s evaluation considered experience, feasibility, and effectiveness. It generated high satisfaction and high adherence among users, fewer readmissions, with an average of 7 ± 4.5 clinical actions per patient, primarily due to abnormal systolic blood pressure or wound-related issues. Conclusions We propose a 6-step methodology to design and validate a high-value digital health care service based on collaborative learning, real-time development, iterative testing, and value assessment.

Abstract
Background New prevention strategies have been advocated to control the progression of HIV/AIDS, such as preexposure prophylaxis (PrEP). The aim of this study is to evaluate the potential changes in the oral and salivary conditions of HIV-uninfected subjects using PrEP. Material and Methods Subjects were evaluated before beginning the medication (T0), at the first follow-up (T1), and at the second follow-up (T2). Xerostomia, presence of untreated cavitated caries, oral hygiene habits, taste, gingival and plaque index, stimulated salivary flow rate (SSFR), and salivary concentrations of calcium, glucose, urea, and total proteins were evaluated. Data obtained were analyzed using statistical tests (p<0.05). Results Forty-seven participants (41 men; 6 women) were evaluated at T0. Thirty (28 men; 2 women) and 17 men were reassessed at T1 and T2, respectively. There was no difference between the SSFR and oral and salivary conditions between T0, T1, and T2 (p>0.05), except for the salivary calcium concentration, that increased at T2 compared to T1 (p=0.02). There was significant difference between taste and xerostomia at T1 (p=0.017), and the need to drink to swallow at T2 (p=0.015). There was significant correlation between the reported amount of saliva and taste (p=0.039, r=-0.378) at T1. Conclusions The prolonged use of PrEP seems to be associated with reports of dry mouth and worsening of taste, possibly associated with increased salivary calcium concentration. Key words:Antiretroviral agents, pre-exposure prophylaxis, saliva, oral health.

Abstract
BACKGROUND AND AIMS Emergency General Surgery (EGS) conditions account for millions of deaths worldwide, yet it is practiced without benchmarking-based quality improvement programs. The aim of this observational, prospective, multicenter, nationwide study was to determine the best benchmark cutoff points in EGS, as a reference to guide improvement measures. METHODS Over a 6-month period, 38 centers (5% of all public hospitals) attending EGS patients on a 24-h, 7-days a week basis, enrolled consecutive patients requiring an emergent/urgent surgical procedure. Patients were stratified into cohorts of low (i.e., expected morbidity risk <33%), middle and high risk using the novel m-LUCENTUM calculator. RESULTS A total of 7258 patients were included; age (mean ± SD) was 51.1 ± 21.5 years, 43.2% were female. Benchmark cutoffs in the low-risk cohort (5639 patients, 77.7% of total) were: use of laparoscopy ≥40.9%, length of hospital stays ≤3 days, any complication within 30 days ≤ 17.7%, and 30-day mortality ≤1.1%. The variables with the greatest impact were septicemia on length of hospital stay (21 days; adjusted beta coefficient 16.8; 95% CI: 15.3 to 18.3; P < .001), and respiratory failure on mortality (risk-adjusted population attributable fraction 44.6%, 95% CI 29.6 to 59.6, P < .001). Use of laparoscopy (odds ratio 0.764, 95% CI 0.678 to 0.861; P < .001), and intraoperative blood loss (101-500 mL: odds ratio 2.699, 95% CI 2.152 to 3.380; P < .001; and 500-1000 mL: odds ratio 2.875, 95% CI 1.403 to 5.858; P = .013) were associated with increased morbidity. CONCLUSIONS This study offers, for the first time, clinically-based benchmark values in EGS and identifies measures for improvement.

Abstract
The Paiva River is considered one of the least polluted rivers in Europe and its watershed has a high conservation value. However, the Paiva River basin suffers pressures related with recurrent disturbances in land use, such as forest fires, agricultural activities, urbanization and pressures that affect the natural hydromorphological conditions and the continuity of watercourses. Blue and Green Infrastructures (BGINs) emerge to improve biodiversity, sustainability and the supply of ecosystem services while improving socioeconomic aspects. Thus, this article aims to identify priority areas in the basin, for intervention with these infrastructures. For that, a spatial multicriteria decision analysis (MDCA) was carried out according to several data related to the Paiva River Basin. As local politicians and responsible entities for the natural resources management are the main experts on the problems and their possible solutions at the local level, they were involved in this decision-making model. Therefore, these specialized stakeholders did the weighting assignment according to the most or least importance of the same for the work. The map of priority locations to implement BGINs was obtained in the sequel. To the top 5 priority areas, stakeholders attributed the best solutions based on nature. The most recommended BGINs were recovery/maintenance of riparian vegetation and conservation and reforestation of the native forest, both presented in four of the five areas, and introduction of fuel management strips presented in three of the five areas. Thus, we concluded that it is extremely important to include the communities and the competent entities of nature and environment management in scientific projects related to conservation, forming a synergy that makes it possible to combine scientific knowledge with local experience acquired in the field. This project uses a very flexible methodology of local data and can be a great example to be implemented in other hydrographic basins anywhere in the world.

Abstract
As for previous communicable diseases, the vaccine against SARS-CoV-2 can be a truly “game-changing” factor to tackle the COVID-19 pandemic. A lot has been discussed about what is the less expensive vaccine and how health expenditures might be overrun with pandemic containment measures. There are interesting questions on cost estimation of this technology that should be discussed. The focus has been mainly on vaccine costs rather than on immunization delivery costs, which might also represent an important constraint. This includes human resources, equipment or maintenance which cannot be ignored. Such programs are highly dependent on labor supply, as well as on opportunity costs of reallocating an important share of health care workers for COVID-19 vaccination. On the other hand, costs regarding prevented health care use on COVID-19, from testing to intensive care unit, cannot be neglected, with associated opportunity costs as well. However, prevention of potentially needed measures such as lockdowns with effects in all spheres of society, such as economy and education, are of utmost relevance and are not commonly accounted for in health technology assessments. Furthermore, vaccines have important effects that are not commonly present in prescription drugs such as herd effect, protection against comorbidities or others to be explored in such a recent disease. Only a few efforts for COVID-19 vaccines' economic evaluations exist. However, at the same time, vaccines (and the rollout of vaccination programs) continue to be developed and improved. Therefore, such assessments will be important for studying boosters or revaccinations later on, but also for future pandemic preparedness. Moreover, such efforts on estimating vaccination cost-effectiveness, considering a wide range of costs, might be essential for sub-population prioritization.

Abstract
Abstract
Issue
The National Health Plan (PNS) 2012-2016 (extended until 2020) is the Portuguese strategic health document that presents the direction of intervention within the Health System. A final evaluation of PNS was foreseen, with National Institute of Health Dr Ricardo Jorge (INSA) being responsible for carrying out this task. The experience gained by INSA in defining a roadmap to be used in this process can be important in steering other actors to policy evaluation.
Description of the problem
In order to analyze the impact of policies, it is necessary to collect evidence that can evaluate the results achieved, and more importantly, identify gaps in implementation and evaluation issues. Herein, we aim to present the methodological approach developed to pave the way to the final assessment of PNS.
Results
As part of the Biennial Collaborative Agreement 2016-2017, WHO sponsored a high-level technical consultative process with relevant experts to address the condition for defining the work plan. It was devised to undertake: i) A scoping review based upon data collected from PNS implementation evidence mapping; ii) A qualitative analysis of the perception from main stakeholders on PNS impact and their expectations. Thus, a matrix of evidence was built to analyze the alignment of PNS at national and local levels, and with the main health framework targets and indicators. Also, online surveys and face-to-face interviews were done with key stakeholders in order to identify evidence gaps and critical factors for the successful PNS implementation, among others.
Lessons
To characterize its implementation and impact on citizens' health, a sound PNS evaluation should be guided by clear assessment questions, supported by validated tools and complemented by international guidance. In addition, a long-term consultative process with key stakeholder support is required to properly identify opportunities, priorities, and outcomes.
Key messages
Institutionalization of an evaluation process as part of public policies life cycle is a powerfull tool to foster learning and crucial to achievement of proposed goals. A clear structure to support the policy evaluation approach is mandatory to guarantee impartiality, independence and transparency on the overall process.

Abstract
Abstract
Issue
Hypertension (HT) is a major and modifiable risk factor for cardiovascular diseases (CVD), which can be caused by excessive salt intake. Portugal has one of the highest mortality rate due to CVD in Europe, mainly due to HT. Thus, reduction of salt intake from food products is one of major strategies advocated to modify blood pressure (BP) and its impact on HT.
Description of the problem
The Portuguese population has excessive daily salt intake mainly due to bread consumption. Thus, in 2017 a voluntary ‘Protocol' was signed between stakeholders with the goal to reduce salt content in bread by 2021. Herein, using a Health Impact Assessment (HIA) approach we aimed to estimate the potential effect in BP from the implementation of this ‘Protocol'. Thus, two national surveys were used to find average values of salt intake and BP on population, while estimates of BP reduction were calculated based upon meta-analysis data.
Results
It was expected that the implementation of the ‘Protocol' could reduce salt ingestion and have a higher BP effect, mostly in more vulnerable populations. In fact, results showed that individuals with low educational level, men, aged and residents in the South region of Portugal were the ones that could more benefit from the ‘Protocol' implementation. However, this study found that the effects were be very low for all groups analysed, suggesting that only slight health gains can occur.
Lessons
The ‘Protocol' as a voluntary agreement is not sufficient to attain the public health targets devised. Following the HIA framework, further complementary and intersectoral integrated measures, through the use of compulsory food and fiscal policies preferably extended to other highly consumed food products, were thus recommended. HIA could be used as a comprehensive tool to assess health impacts, supporting at each national context the design and implementation of effective strategies to promote salt intake reduction and effectively prevent hypertension.
Key messages
The systematic use of HIA to design the appropriate policy framework and to inform adequately political decision-making is crucial to promote health and prevent Non-Communicable Diseases. Voluntary agreements should be complemented by other integrated measures to improve the efficacy of policies aiming to reduce salt intake and prevent hypertension.

Abstract
Abstract
Introduction
Patients hospitalized due to acute heart failure (AHF) compose a heterogeneous population whose prognosis is difficult to forecast. Previously, BAUN score has proven to be able to accurately predict in-hospital mortality (IHM) in AHF. We aimed to evaluate BAUN score performance in the prediction of long-term outcomes in this population, comparing it to the recently validated Get With The Guidelines (GWTG) score.
Methods
A retrospective analysis of 1052 patients admitted to a Cardiology ward due to AHF was performed. 268 patients were excluded due to data omission or therapy with sacubitril/valsartan. Using the variables systolic blood pressure, urea, brain natriuretic peptide and sodium at admission, BAUN score was calculated, ranging from 0–28 points. GWTG score was also calculated at the index event. ROC curve analysis was used to compare the predictive value of the two scores for IHM. Kaplan-Meyer and Cox-regression analysis were performed to evaluate BAUN score prediction ability for 24-month mortality (24-MM) and for the composite endpoint of 24-month rehospitalization or death (24-MH).
Results
Mean patient age was 77 (±10) years; 51% were men. Mean left ventricle ejection fraction (EF) was 49% (±16.4). An EF<40% was present in 31% of patients. IHM, 24-MM and 24-HM were 6.5%, 17.1% and 57.8%, respectively. Mean BAUN score was 7 (±5.64). Mean GWTG score was 49.7 (±9.8). ROC curve analysis for IHM prediction revealed a better performance of the BAUN score (AUC: 0.738p, <0.001) in comparison with GWTG score (AUC: 0.687, p<0.001). Patients were stratified into subgroups according to BAUN risk score – very-high risk (≥22), high risk (16–21), intermediate risk (5–15) and low risk (<5). Kaplan-Meyer analysis revealed a significant difference in 24-MM according to risk subgroup (very high: 35%, high: 26.7%, intermediate: 19.5%, low risk: 12.7%, χ2=16.304, p=0.001). When stratified by non-reduced or reduced EF (≥40% or <40%), there was still a significant mortality difference in subgroups with reduced (p=0.007) and borderline significant in patients with nonreduced EF (p=0.05). Kaplan-Meyer analysis also revealed a significant difference between subgroup risk for 24-MH (51%; 63.8%; 63.3% and 75%, respectively, for low, intermediate, high and very-high risk, χ2=21.237, p<0.001). Cox regression analysis demonstrated that BAUN score independently predicts 24-MM (HR: 1.056, p=0.043) and 24-MH (HR: 1.033, p=0.048), even after adjustment for other prognostic markers, such as atrial fibrillation, coronary artery disease, previous myocardial infarction, age, EF and GWTG score.
Conclusion
BAUN outperforms GWTG score for IHM prediction in AHF. It also independently predicts 24-MM and 24-MH. Its use may identify patients with high risk of mortality/readmission, in need of specialized care, and those patients with low risk of death, who might be candidates for lenient surveillance.

Abstract
Abstract
Introduction
The outcomes of reperfusion in ST-segment Elevation Myocardial Infarction (STEMI) are time-dependent, and percutaneous coronary intervention (PCI) should be performed within 60 minutes from hospital admission in PCI centers – door-to-balloon time (D2B). The association between Off-Hours Admission (OHA) and long-term outcomes is controversial when considering contemporary organized STEMI networks.
Purpose
This study aims to analyze how OHA influences D2B and long-term mortality.
Methods
Retrospective study of consecutive STEMI patients (pts), admitted in a PCI-centre with a local Emergency Department, between 2010 and 2015. Pts submitted to rescue-PCI were excluded. OHA was defined as admission at night (8p.m. to 8a.m), weekends and nonworking holidays. Predictors of OHA and D2B were studied by logistic regression analysis. Demographic, clinical, angiographic and procedural variables were evaluated using stepwise Cox regression analysis to determine independent predictors of 5-year all-cause mortality (5yM). The cumulative incidence of 5yM stratified by hours of admission was calculated according to the Kaplan-Meier method.
Results
Of 901 pts, 472pts (52.4%) were admitted during off-hours. These pts were younger (61±13 vs 64±12, p=0.002) and had a lower median patient-delay time (128min vs 157min, p=0.014). Clinical severity at presentation, defined by systolic arterial pressure and Killip-Kimball (KK) class, did not differ between groups. OHA did not impact D2B (89 min vs 88 min, p=0.550), which was in turn influenced by age ≥75y (OR 1.85, 95% CI 1.31–2.61, p<0.001). Mean clinical follow-up (FUP) was 68±37 months, with 75.1% of pts achieving a FUP >5 years. 5yM rate was 9.7%. After multivariate cox regression analysis, independent determinants of long-term mortality were age (HR 1.05, 95% CI 1.02–1.08, p<0.001), previous history of heart failure (HR 6.76, 95% CI 1.32–34.72, p=0.022) and pulmonary disease (HR 3.79, 95% CI 1.16–12.33, p=0.027), presentation with KK ≥2 (HR 2.82, 95% CI 1.32–6.01, p=0.007) and radial artery access in catheterization (HR 0.39, 95% CI 0.18–0.83, p=0.014) – figure 1. Although there was an association between a higher D2B time and 5yM (87min vs 101min, p=0.024), neither OHA nor D2B were independent predictors of long-term mortality – figure 2.
Conclusion
OHA did not seem to influence D2B and long-term STEMI outcomes in our PCI-centre. 5yM was mostly influenced by patient characteristics and clinical severity at presentation.

Abstract
Abstract
Introduction
Acute coronary syndrome (ACS) is a clinical entity which includes a heterogeneous group of patients with different outcomes. Risk scores are in this setting a resourceful tool to identify the subset of patients with a worse prognosis, in order to plan therapeutic and surveillance strategies.
Aim
To create a risk score – Laboratory Risk Score (LRS) – which exclusively includes analytical and echocardiographic parameters, as a predictor of adverse outcomes (in-hospital mortality and 1-year mortality), and compare it with other well-known scores: GRACE Score (GS) and TIMI-score (TS).
Methods
A retrospective cohort study was conducted, which included patients admitted in the Cardiology Department with the diagnosis of ACS. In order to calculate the new LRS, the authors attributed the value of 1 to each of the satisfied condition from the following: leucocytes >11,7g/L, hemoglobin <13.3g/dL, red cell distribution width >14%, prothrombinemia <90%, glycaemia at admission >143mg/dL, urea >53.5mg/dL, creatinine >1.16mg/dL, reactive C-protein >1.0mg/dL, maximum troponin >35.0ng/dL, natriuretic brain peptide >416 pg/dL and left ventricular ejection fraction <40%. LRS resulted from the sum of the satisfied conditions.
ROC curves for LRS, GS and TS to predict in-hospital mortality and to predict 1-year mortality were constructed. The statistical analysis was performed in SPSS and Medcalc. p value <0.05 was considered statistically significant.
Results
1714 patients (70.4% male, average age 69±13 years-old) were included in this study. Intra-hospital mortality rate was 6.8% and 1-year mortality rate after de discharge was 4.8%.
The areas under the ROC curves for predicting in-hospital mortality were the following: 0,790 (LRS, p<0,001), 0,793 (GS, p<0.01), 0.817 (TS, p<0.001). For predicting 1-year mortality, the areas under the ROC curves were: 0,715 (LRS, p<0,001), 0,761 (GS, p<0,001), 0.742 (TS, p<0.001). Pairwise comparison of ROC curves showed no significant differences between the scores.
Conclusion
The above-mentioned risk scores, including the new LRS, are obtained with non-invasive and widely available parameters and displayed a good performance in predicting in-hospital and 1-year mortality. Pairwise comparison of ROC curves demonstrated that the new laboratorial score was not inferior predicting adverse outcomes. The SRL is an easily obtained score, that shows a statistical significance in predicting mortality, especially the prediction of in-hospital mortality.

Abstract
Abstract
Introduction
Global longitudinal strain (GLS) is considered a more sensitive marker of systolic dysfunction than other measures commonly used in clinical practice, such as left ventricle ejection fraction (EF). Our objective was to evaluate the impact of reduced GLS in death and cardiovascular events in patients hospitalized due to heart failure with mid-range or preserved ejection fraction, with previous history of acute myocardial infarction.
Methods
A retrospective analysis of 170 patients admitted to a Cardiology ward due to acute heart failure (AHF) was performed. Patients with reduced EF (Simpson biplane method - EF<40%) were excluded based on echocardiographic evaluation after AHF stabilization. GLS measured by “speckle tracking” technique was calculated for each patient. Measurements were made by the same operator to minimize interoperator variability. Mann-Whitney U test was used for univariate analysis. Kaplan-Meier survival plots and Cox-regression analysis were performed to assess differences in 12-month mortality (12MM) and in the composite endpoint of cardiovascular event or death (12CVM) at 12 months.
Results
A total of 127 patients were included. Mean patient age was 64 (±14) years; 72% were men. 48% of patients had history of ST elevation AMI. Mean EF was 54% (±8) and mean GLS was −14.3 (±3.8). Rates of 12MM and 12CV M were 14.2% and 19.3%, respectively. A statistically significant association between 12MM and 12MCV was found in univariate analysis for GLS (p<0.001). Kaplan-Meyer survival plots revealed that a compromised GLS (<−16) was associated with significantly increased 12MM (23% vs 2.5%, X2: 7.999, p=0.005) and 12CVM (26.6% vs 10%, X2: 4.139, p=0.042). When stratified by mid-range vs preserved EF, GLS <−16 was associated with worse outcomes, although the results did not reach statistical significance (p>0.05). However, when considering a severely compromised GLS (<−13), GLS was significantly associated with increased 12MM (52% vs 8.3%, X2: 5.533, p=0.019) and 12CVM (50% vs 8.3%, X2: 4.970, p=0.026), in the subgroup of patients with heart failure with mid-range EF. Cox-regression analysis demonstrated that GLS was independently associated with 12MM (HR: 0.668p, <0.001) and the 12CVM composite endpoint (HR: 0.819, p=0.008), even after adjustment for other important prognostic markers such as chronic kidney disease, pulmonary disease and diabetes, with significant hazard ratio reduction for each positive point increase in GLS.
Conclusion
GLS is an independent predictor of 12MM and 12CVM in patients hospitalized due to AHF, with an EF ≥40% and previous history of acute myocardial infarction. In the subgroup of patients with heart failure with mid-range EF, a severely compromised GLS (<−13) is a strong predictor of 12MM and 12CVM.

Abstract
Abstract
Introduction
Patients hospitalized due to heart failure (HF) constitute a heterogeneous population whose prognosis is difficult to forecast. The purpose of this study was to create a model based on simple bedside recordable echocardiographic, analytical and objective clinical parameters that could accurately predict mortality and/or rehospitalization risk in different stages of HF course.
Methods
A retrospective analysis of 347 patients admitted to a Cardiology ward due to decompensated HF was performed. The echocardiographic variables pulmonary artery systolic pressure (PSAP) and E/e' ratio, and the analytical/clinical variables systolic blood pressure (SBP), urea and brain natriuretic peptide (BNP) were selected for inclusion. Subgroups were created for each variable and an odds ratio (OR) for the risk of in-hospital mortality (IHM) was calculated. A numerical value proportional to the OR was attributed to each subgroup. A score was created, ranging from 0–47 points, corresponding to the sum of the classification attributed to each variable. ROC curve analysis was used to assess predictive value of the score for IHM. Kaplan-Meyer and Cox-regression plots were used to assess mortality (24MM) and the composite endpoint of HF rehospitalization or death at 24 months (24HM).
Results
Mean patient age was 78 (±9) years; 51% were men. Score variable means were - PSAP: 47 (±15) mmHg; E/e': 16.8 (±7.8); SPB: 138 (±31) mmHg; Urea: 71 (±35) mg/dl; BNP: 911 (±995) pg/ml. Mean ejection fraction (EF) was 48% (±16). 35% of patients had EF<40%. IHM, 24MM and 24HM were 3.5%, 17.1% and 63.6%, respectively. A statistically significant association between IHM and PSAP, E/e', BNP, urea and SBP (p<0.05) was found on univariate analysis. ROC curve analysis of AHFM revealed an AUC of 0.785 (p=0.001) for IHM risk prediction. The cut-off point with most sensitivity (S) and specificity (E) obtained using the Youden index (0.4246) was 18 (S≈75%; E≈67%), associated with significant difference in IHM (1.3% vs 7.6%). IHM by score interval was 1.3%, 3.1% and 25%, respectively, for the intervals 0–18, 19–29 and ≥30. ECHO-AHF score <13 predicted in-hospital survival in all patients. Kaplan Meyer survival analysis by subgroup revealed significant differences in 24MM according to AHFM risk category (13.8% vs 21.9% vs 30.8%, respectively, χ 2= 17.217 p<0.001), but not for 24 MH. Cox-regression analysis demonstrated that AHFM score remained a significant independent predictor of 24MM (HR: 1.067, p=0.05), even after adjustment for other variables, such as coronary disease, chronic kidney disease, atrial fibrillation, EF and diabetes.
Conclusion
AHFM score is an accurate model for predicting IHM and long-term risk of HF death. Its use may help to identify patients with high risk of mortality, in need of specialized care, and those with lower risk of death, who might be candidates for early discharge or lenient follow-up.

Abstract
Abstract
Introduction
Left Ventricular Non-Compaction (LVNC) is a rare and underdiagnosed cardiomyopathy, characterized by hypertrabeculation of the left ventricle. This disease is associated with high rates of morbidity and mortality; however, its main adverse prognostic factors are not well established.
Aim
To create a risk score for LVNC based on echocardiographic criteria (EcoScore) to predict the occurrence of adverse events.
Methods
The authors included patients with the diagnosis of LVNC, according to the Jenni Criteria. Clinical and echocardiographic data were evaluated and the occurrence of the following adverse events was reported: hospitalizations due to supraventricular or ventricular tachyarrythmias and heart failure, acute myocardial infarction, stroke, heart transplant and death. The follow-up time was 24 months. ROC curves to predict the occurrence of at least one adverse event were constructed for each echocardiographic parameter. The optimal cut-off obtained from each ROC curve was then used to attribute points (1 point per parameter). The EcoScore resulted from the sum of the obtained points. The authors finally created a ROC curve to predict the occurrence of any adverse event for the EcoScore. The statistical analysis was performed in SPSS. p value <0.05 was considered statistically significant.
Results
33 patients (48.5% male, age at diagnosis 45.9±21 years) were included in this study. The optimal cut-offs for each parameter obtained from the ROC curves were the following: left ventricle dyastolic diameter >55mm, left atrial diameter >40mm, pulmonary artery systolic pressure >22mmHg and left ventricle ejection fraction <40%. The area under the curve for the EcoScore to predict any adverse event was 0.850 (p=0.017) and an EcoScore >1 had a sensibility of 85.7% and a specificity of 70%.
Conclusion
The EcoScore accurately predicted the occurrence of at least one adverse event in this population. Thus, it could be a good tool in the daily practice to select patients who may benefit from a more aggressive surveillance and treatment.

Introduction
Individualized estimation of prognosis after cardiac resynchronization therapy (CRT) remains challenging. Outcomes in this group of patients are influenced by multiple factors and a comprehensive and customized approach to estimate prognosis after CRT is lacking
Aims
To develop and validate a simple prognostic score for patients implanted with CRT (NISAR-F score), based on readily available clinical and echocardiographic variables to predict the combined endpoints of death or hospitalization in 24 months.
Methods
A single-centre retrospective study was conducted with inclusion of all consecutive patients who underwent CRT implantation between 2012 and 2019. Follow-up started after CRT implantation and ended upon death, hospitalization or 24 months after study entry. Survival analysis was performed using a multivariate Cox regression model, in order to analyze the effect on survival /hospitalization in 24 months of the following factors: age, gender, NYHA Class III-IV, ischemic heart failure, type 2 diabetes, arterial hypertension, dyslipidemia and ejection fraction < 21%. According to the analysis, points were attributed to each factor. Afterwards, the NISAR-F score was calculated for each patient, summing the points of each variable. The authors finally created ROC curves for the NISAR-F score to predict the occurrence of the combined endpoint in 2 groups of patients: CRT responders (ejection fraction increase of at least 10% after CRT implantation) and CRT non-responders. The statistical analysis was performed in SPSS.
Results
102 patients were included in the study (75.4% male, mean age 68 ± 10.46 years). 10(9.8%) of the patients were re-hospitalized and 8 (7.8%) died during the 24-month follow-up. After calculating NISAR-F score for each patient, area under ROC curves were obtained. The analysis of the ROC curves allows us to confirm the good performance of the score created [responders group (AUC 0.812) vs non-responders (AUC 0.721)].
Conclusion The NISAR-F score is a useful tool to predict the combined endpoint (mortality and hospitalization in 24 months) after CRT implantation, in both responders and non-responders, revealing good performance of this new and simple score based only on clinical and echocardiographic variables.

Introduction
Several studies have suggested a relationship between dyslipidemia and atherogenesis, which displays a main role in the pathophysiology of Acute Coronary Syndrome (ACS).
Aim
To compare the lipid profile between younger (<55 years) and older (≥55 years) patients admitted due to ACS.
Methods
A single-centre retrospective study was conducted, with inclusion of all consecutive patients admitted in the Cardiology Department due to ACS. Several analytical parameters were evaluated, including total cholesterol (CT), HDL cholesterol (HDL), LDL cholesterol (LDL) and triglycerides (TG) and CT/HDL, LDL/HDL and TG/HDL ratios were calculated. All parameters are presented in mg/dL. Afterwards, comparison of these data between younger (age < 55 years, Group-A) and older (age≥55 years, Group-B) patients was done. Statistical analysis was performed with SPSS and a p value < 0.05 was considered statistically significant.
Results
1168 patients (70.1% male, mean age 69 ±12 years) were included in this study. 15.8% of patients were from Group-A. Mean levels of the analysed parameters were the following: CT 176 ± 55, LDL 111 ± 45, HDL 40 ± 12 and TG 137 ± 102. The following mean ratios were obtained: CT/HDL 4.6 ± 1.9, LDL/HDL 2.9 ± 1.4 and TG/HDL 3.8 ± 3.5. Comparison of the analysed parameters and calculated ratios is exhibited in table 1.
Conclusion
Overall, a worse lipid profile was observed in younger patients. This data reveals the role of dyslipidemia in coronary heart disease, which displays a main role in atherosclerosis at a younger age. This fact highlights the importance of adopting a healthy lifestyle and the adherence to primary and secondary prevention measures of cardiovascular events.

Introduction
Several studies have concluded that smoking increases mortality in patients with coronary disease. On the other hand, a J-shaped dose-effect curve has been used to describe the relationship between alcohol and cardiovascular mortality. According to the majority of studies, a moderate intake of alcohol is associated with a decrease in mortality, while an excessive alcohol intake appears to increase mortality.
Aim
To evaluate the effect of smoking and excessive alcohol intake in hospital mortality and 1-year mortality in patients hospitalized due to acute coronary syndrome (ACS).
Methods
A single-centre retrospective study was conducted, with inclusion of all consecutive patients admitted in the Cardiology Department due to ACS. Follow-up started after hospital admission and ended upon hospital death, death within the following 12 months or 12 months after study entry. Patients were divided in two groups: smokers (Group-A) and non-smokers (Group-B), to analyse the effect of smoking in hospital mortality and 1-year mortality. To analyse the effect of excessive alcohol intake, patients were also divided in other two groups: Group-C (excessive drinkers) and Group-D (non-excessive drinkers). Statistical analysis was performed with SPSS and a p value < 0.05 was considered statistically significant.
Results
1120 patients (68.9% male, mean age 69.12 ± 12.67 years) were included in this study. 20.5% were smokers and 3.2% had a previous excessive alcohol intake.
Between Group-A and Group-B, a statistically significant difference was observed in gender (93.1% male in Group-A vs 62.9% male in Group-B, p = 0.002), but not in age (p = 0.116). Hospital mortality rates in Group-A and Group-B were respectively 6.0% and 8.7% (p = 0.191) and 1-year mortality rates were 3.1% vs 5.1% (p = 0.239).
Between Group-C and Group-D, a statistically significant difference was observed in gender (94.4% male in Group-C vs 69.8% male in Group-B, p < 0.001), but not in age (p = 0.730). Hospital mortality rates in Group-C and Group-D were respectively 25% and 9.6% (p = 0.003) and 1-year mortality were 3.8% vs 6.6% (p = 0.577).
Conclusions
Smoking did not have a positive or negative effect in hospital mortality and 1-year mortality. However, excessive alcohol intake was associated with increased hospital mortality in this population.

Abstract
Chagas disease is caused by the protozoan parasite Trypanosoma cruzi and affects 7 million people worldwide. Considering the side effects and drug resistance shown by current treatments, the development of new anti-Chagas therapies is an urgent need. T. cruzi hypoxanthine phosphoribosyltransferase (TcHPRT), the key enzyme of the purine salvage pathway, is essential for the survival of trypanosomatids. Previously, we assessed the inhibitory effect of different bisphosphonates (BPs), HPRT substrate analogues, on the activity of the isolated enzyme. BPs are used as a treatment for bone diseases and growth inhibition studies on T. cruzi have associated BPs action with the farnesyl diphosphate synthase inhibition. Here, we demonstrated significant growth inhibition of epimastigotes in the presence of BPs and a strong correlation with our previous results on the isolated TcHPRT, suggesting this enzyme as a possible and important target for these drugs. We also found that the parasites exhibited a delay at S phase in the presence of zoledronate pointing out enzymes involved in the cell cycle, such as TcHPRT, as intracellular targets. Moreover, we validated that micromolar concentrations of zoledronate are capable to interfere with the progression of cell infection by this parasite. Altogether, our findings allow us to propose the repositioning of zoledronate as a promising candidate against Chagas disease and TcHPRT as a new target for future rational design of antiparasitic drugs.

Abstract
The present study investigates - from an environmental perspective - the processes that lead to the conversion of waste plastics into recycled plastic pellets to be used either as an additive (wet method) or as a replacement of natural aggregate (dry method) in the production of asphalt mixes. Data from recycling facilities in Victoria, Australia, were collected and used as the basis for a comparative life cycle assessment (LCA) study. Analyses were conducted by considering several replacement ratios of virgin material by its recycled counterpart in the so-called wet and dry method. A case study considering the production of recycled-plastic asphalt to be applied in the construction of a typical surface layer of a road in Victoria was evaluated. In general, the results show that recycling plastics as a polymer for bitumen modification and as a synthetic aggregate replacement in asphalt mixes has the potential to be environmentally advantageous compared to their virgin counterpart (i.e. virgin polymers and natural quarry aggregates).

Abstract
OBJECTIVES Spain is close to HCV microelimination, so rates of recently acquired HCV infection (RAHC) should decrease. Nowadays, men who have sex with men (MSM) carry the highest risk of HCV acquisition. Our aim was to estimate the incidence of and the factors associated with RAHC, together with reinfection rates, among patients sexually infected by HIV. METHODS Primary RAHC infection was diagnosed when anti-HCV antibody seroconversion was documented. In anti-HCV positive patients, initially without HCV viraemia, a diagnosis of reinfection was established if plasma HCV RNA was detected. RESULTS All 350 patients tested negative for anti-HCV at baseline and had at least one follow-up visit. Among them, there were 16 RAHC cases from 2016 to 2019. RAHC incidence rates [IR (95% confidence interval, CI)] per 100 person-years were 3.77 (0.5-12.9) in 2016, 1.85 (0.6-4.3) in 2017, 1.49 (0.4-3.8) in 2018 and 1.98 (0.6-4.5) in 2019. Only previous sexually transmitted infections [incidence rate ratio (IRR) = 18.23, 95% CI: 1.93-172.1; P = 0.011], male sex (IRR = 8.33, 95% CI: 1.38-54.15; P = 0.026) and sharing chem-sex drugs (IRR: 4.93, 95% CI: 1.17-20.76; P = 0.030), were independently associated with RAHC. Four out of 42 (9.5%) patients became reinfected. CONCLUSIONS The incidence of RAHC among HIV-infected patients showed a decrease after 2016, although a lower but steady incidence of residual cases still remains. HCV reinfections showed a similar pattern. New infections were associated with sharing chem-sex drugs among MSM.

Abstract
Water utilities collect, store and manage vast data sets using many information systems (IS). For infrastructure asset management (IAM) planning those data need to be processed and transformed into information. However, information management efficiency often falls short of desired results. This happens particularly in municipalities where management is structured according to local government models. Along with the existing IS at the utilities' disposal, engineers and managers take their decisions based on information that is often incomplete, inaccurate or out-of-date. One of the main challenges faced by asset managers is integrating the several, often conflicting, sources of information available on the infrastructure, its condition and performance, and the various predictive analyses that can assist in prioritizing projects or interventions. This paper presents an overview of the IS used by Portuguese water utilities and discusses how data from different IS can be integrated in order to support IAM.

Abstract
Abstract
Introduction
Right ventricular (RV) adaptation to the increased pulmonary load is a key determinant of outcomes in pulmonary hypertension (PH). Pulmonary vascular resistance (PVR) is widely recognized as haemodynamic measure of RV overload. Cardiac filling pressure (CFP), RV stroke work (RVSW), pulmonary artery (PA) compliance and PA pulsatility index (PAPi) are emerging as new haemodynamic parameters to assess RV function.
Aims
To assess the predictive value of CFP, RVSW, PA compliance and PAPi in PH and to compare it with standard haemodynamic parameters.
Methods
Retrospective study including all consecutive right heart catheterizations performed from April/2009 to October/2019 in a PH referral centre. Procedures presenting PH were selected [mean pulmonary arterial pressure (mPAP) >20 mmHg, according to the new definition of the 6st World Symposium on PH]. CFP was calculated as [right atrial pressure (RAP) − pulmonary capillary wedge pressure], value >0.63 associated with RV failure; RVSW as CO / [(heart rate × (mPAP-RAP) × 0.0136], value <15; PA compliance [SV / pulmonary arterial systolic pressure (PASP) − pulmonary arterial diastolic pressure (PADP)], value <2.5]; PAPi [(PSAP − PDAP) / RAP, value <1.85]. Multivariate logistic regression was used to identify predictors of all-cause mortality. Receiver operating characteristic (ROC) curves and area under curve (AUC) were used to assess discrimination power.
Results
From a total of 569 procedures, 470 fulfilled PH criteria: mean age 57.9±16.0 years, 67.7% female, 35.5% performed under pulmonary vasodilator therapy. Pre-capillary PH was diagnosed in 71.9% of cases. Chronic thromboembolic PH was the most common subtype (34.4%). Concerning standard haemodynamic parameters: mPAP was 39.0±12.0 mmHg, mean RAP 8.0±5.0 mmHg, mean RVP 7.5±5.0 uWood and CI 2.5±0.8 L/min/m2. Median value of CFP was 0.6 (IQR 0.4–0.8), RVSW 15.2 (IQR 9.7–25.0), PA compliance 2.1 (IQR 0.9–2.9) and PAPi 5.3 (IQR 3.2–8.5). All-cause mortality rate was 22.8%. Patients experiencing adverse events had lower values of cardiac index (2.3±0.6 vs 2.6±0.8 L/min/m2, p<0.01), RVSW (11.2 vs 16.7, p<0.01) and PA compliance (2.2 vs 2.9, p<0.01) and higher values of PVR (10.0±5.5 versus 6.8±4.6 uWood, p<0.01) and mean RAP (9.9±6.1 versus 7.4±4.5, p<0.01). Multivariate logistic regression identified 2 independent predictors of adverse events: mean RAP (OR 1.08, 95% CI 1.02–1.13, p<0.01) and PVR (OR 1.11, 95% CI 1.06–1.17, p<0.01). According to the ROC curves, new haemodynamic parameters did not have acceptable discrimination power to adverse events occurrence (figure).
Conclusions
In this study, new haemodynamic parameters to assess RV overload in PH were not independent predictors of adverse events as opposite to standard haemodynamic parameters. Further studies are needed to clarify their predictive value, as it has major implications for understanding the arterial load in diseases of the pulmonary circulation.

Abstract
Abstract
Introduction
Thermodilution (TD) and indirect Fick (IF) methods are widely used to measure cardiac output (CO). They are often used interchangeably to make critical clinical decisions, yet few studies have compared these approaches concerning agreement and comparative prognostic value as applied in medical practice.
Purpose
To assess agreement between TD and IF methods and to compare how well these methods predict mortality.
Methods
Retrospective cohort study including all consecutive right heart catheterizations performed in a referral pulmonary hypertension (PH) centre from 2010 to 2018. Cardiac index (CI) was calculated by indexed CO to body surface area. PH was classified according to the new definition of the 6st World Symposium on Pulmonary Hypertension 2018 [mean pulmonary arterial pressure (mPAP) >20 mmHg]. Patients with cardiac or extra-cardiac shunts or significant (moderate to severe or severe) tricuspid regurgitation were excluded. All-cause mortality over 1 year after right heart catheterization was recorded. Logistic regression was used to identify predictors of the adverse event.
Results
From a total of 569 procedures, 424 fulfilled the inclusion criteria: mean age 56.7±15.4 years, 67.3% female. Haemodynamic parameters were diagnosed of PH in 86.2% of cases: mPAP 35.3±15.3 mmHg, 83.6% pre-capillary subtype, 42.9% belonging to group 4 (chronic thromboembolic pulmonary hypertension) and 26.6% to group 1 (pulmonary arterial hypertension). Mean values of CO and CI were, respectively, 4.5±2.8 L/min and 2.5±0.8 L/min/m2 measured by TD and 4.6±2.4 L/min and 2.6±1.3 L/min/m2 measured by IF method. There was a median difference (IF minus TD) of - 0.03 / min to CO and - 0.05 L/min/m2 to CI but both meausres correlated only modestly (r=0.6 to TD and r=0.5 to IF). One-year all-cause mortality rate was 5.4% (median time to death was 50.5 days). Lower values of CO and CI assessed by TD were significantly associated with all-cause mortality occurrence (CO TD: 4.5±1.3 L/min versus 3.6±1.0 L/min, p<0.01; CI TD: 2.6±0.7 L/min/m2 versus 2.1±0.4 L/min/m2, p<0.01). No association was observed between CO (p=0.31) and CI (p=0.42) measured by IF method and the adverse event. Logistic regression identified 2 independent predictors of all-cause mortality: TD CO (OR 0.55, 95% CI 0.38–0.79, p<0.01) and TD CI (OR 0.34, 95% CI 0.17–0.67, p<0.01). Similar results were obtained when patients diagnosed with PH were independently analyzed.
Conclusions
There is only modest agreement between TD and IF CO and CI estimates. Despite being more time-consuming, TD measurements were predictors of all-cause mortality and present a highest prognostic value. These findings favored their used over IF in clinical practice.

Abstract
Abstract
Background
Prenatal exposure to environmental risk factors are one of the known causes of congenital anomalies (CA). In 2015, a cluster of anorectal anomalies, a rare malformation, in Setúbal district raised interest in researchers. The aim of study was to assess the impact of prenatal exposure of the mothers on the occurrence of CA in the offspring.
Methods
A Case-control study (1:2) was implemented between 2016-2019. Newborns with CA (cases) and newborns without CA (controls) are identified and recruited. Parents were personally interviewed by a health professional using a standardized questionnaire. A descriptive analyses was performed and cases and controls were described based on maternal residence during pregnancy. Chi-square test was used to compare cases and controls.
Results
97 cases and 194 controls were identified. There was a male predominance in the case group (60 vs. 34) and no difference in gestational age between case and control groups. The mean birth weight was similar (3115g in cases vs. 3221g in controls). There was no difference related to mean mother's age nor the presence of maternal chronic disease. Smoking had more expression in the case group (21,2% vs. 16,3%). Moita (37,8%) is the municipality with higher frequency of cases. Musculoskeletal anomalies were the most frequent (35.4%), followed by genital (22.2%) and other anomalies (11%). During the study period, five cases with anorectal anomalies were reported, 4 of them born at 2016 and in 3 the mothers residence place was Moita.
Conclusions
In this study, the high proportion of cases from Moita suggests a possible environmental exposure to a teratogenic agent. Also smoking during pregnancy could be a high risk to anorectal anomalies, as suggested in other studies. More investment in public health measures could protect population from harmful environments.
Key messages
Pprenatal exposure to environemental risk factors increase the risk of congenital anomalies. Mothers residence and place of work could be a risk factor to pregnancy.
