Abstract
The development of implant metal-free surfaces has gained attention since non-benefic results have been reported related to the metallic ions released from metal implants to the human body. Ceramic coatings have been proposed as a possible solution however, the detachment of these coatings, during implantation or even in function, can compromise its function. In order to overcome this problem, this work proposes a novel hybrid Ti6Al4V-ZrO2 surface, starting with laser texturing of the Ti6Al4V substrate by Laser Nd:YV04, followed by the allocation of the zirconia (ZrO2) powder and its subsequent sintering by hot pressing process. Results revealed that zirconia strongly adheres to titanium textured surfaces since no detachment was found under tribological and adhesion scratch tests. Moreover, the tribological results showed that the incorporation of zirconia into textured titanium surface reduces significantly the wear rate of titanium (≈93%), which is a good indicator of low metallic particles/ions released to the body. These results suggest that this novel surface with good aesthetic properties and improved wear resistance (given by zirconia) and mechanical resistance (from titanium) can be a promising solution for dental implants, especially for implant/abutment or abutment/ceramic contact zones, and thus have a huge impact on the long-term performance of implants.

Abstract
Abstract
Background
Adult Congenital Heart Disease (ACHD) patients at increased risk for thromboembolic events are often treated with oral anticoagulation. While vitamin-K antagonists have been the agent of choice for decades, the use of non-vitamin K oral anticoagulants (NOAC) is increasing. We aimed to assess the safety and effectiveness of NOAC in ACHD patients at our centre.
Methods
This is a single-centre study enrolling all patients with ACHD treated with a NOAC from inception to November 2021. Data was collected using a standardized questionnaire applied to all patients by means of a telephone visit, in parallel with a detailed retrospective chart review. The endpoints of interest included thromboembolic and haemorrhagic events, defined as per the standardized International Society on Thrombosis and Haemostasis (ISTH) scale.
Results
Overall, 36 ACHD patients were enrolled [mean age 53±15 years; female sex – 66.7%; previous stroke – 33.3%; median HAS-BLED and CHA2DS2-VASc score – 1 (1–2) and 3 (2–5), respectively], predominantly with moderate or complex congenital defects (52.7%), of whom 14, 8, 8 and 4 were treated with rivaroxaban, apixaban, edoxaban and dabigatran, respectively. Two-thirds had their first NOAC prescription in the latest 3 years (Figure 1). The most common indication for anticoagulation was atrial fibrillation or flutter (77.8%). Over a median time of 36 (18–63) months on NOAC treatment, there were no patients with thromboembolic events, whilst 13 (36.1%) had a haemorrhagic event – annualized event rate of 12.0 (6.9–24.1%). All bleeding events were minor, most often self-limited gingival haemorrhage or epistaxis (n=7) or menorrhagia (n=3). Nasal cautery was needed to treat recurrent epistaxis in 3 patients, whilst 3 other required oral iron supplementation. The strongest predictor of any haemorrhage was a prior cardiovascular hospitalization (HR 3.88; p=0.027).
Conclusions
The use of NOAC in ACHD patients has been increasing in our centre, with encouraging results. The present findings suggest that NOAC are safe and may be effective for thromboembolic event prevention in heterogeneous forms of ACHD.

Abstract
Abstract
Background
Exercise capacity is usually reduced in Fontan patients, however there is a subset of patients who have normal exercise capacity and better outcomes, the “Super-Fontans”. The aim of this study was to characterize a cohort of Fontan patients undergoing cardiopulmonary exercise testing (CPET) and identify predictors of better functional capacity.
Methods
Single center retrospective analysis of consecutive Fontan patients aged >10 years old who underwent CPET, between March 2018 and May 2021.
Peak respiratory exchange ratio1.05 defined maximal CPET. Peak VO2 (pVO2) as a percentage of its predicted value was used as reference value to stratify patients in tertiles.
Patients in 3rd tertile, with a percentage predicted pVO2 superior to 75%, were considered good-performers.
Blood tests and transthoracic echocardiogram (TTE) were performed on the same day. Additional data were collected from electronic charts.
Results
In total, 49 patients were included (mean age 19±7 years old, 67% male) with intra or extracardiac conduit implanted in mean 12±7 years prior to the CPET.
The most common primary diagnoses were tricuspid/pulmonary atresia (43%), followed by unbalanced complete AV septal defect (14%) and double inlet left ventricle (14%). 12 patients had a systemic right ventricle. All, except 5 patients, had preserved systolic ventricular function and 37% had moderate to severe AV regurgitation.
The majority had normal hemoglobin levels (median 15.6 g/dL), hepatic enzymes (median total bilirubin 0.8 mg/dL), renal function (median creatinine 0.8 mg/dL) and low NT-proBNP (median 122 pg/mL).
All patients had maximal CPET, median %VO2 at VT1 was 57% of peak and mean pVO2 was 66±14% of the predicted. Most patients (69%) showed exercise limitation due to cardiovascular cause, followed by O2 desaturation, present in 22% of CPETs. The age of Fontan completion was not associated with functional capacity (p=0.6).
The good-performer group comprised 13 patients (27%), all in sinus rhythm, of which 10 were physically active. Compared with the remainder, this group had higher VO2 at VT1 (18.7 vs. 14.6, p=0.01) and VO2 at VT2 (25.9 vs. 22.1, p=0.02), both in mL/kg/min. Also, peak heart rate (% predicted) (90 vs. 81, p=0.03) was higher in this subgroup – fig.1. Conversely, differences on TTE parameters (GLS and AV valve regurgitation) and blood biomarkers were not statistically significant. On multivariable analysis, no single variable predicted better functional capacity.
Conclusion
In our Fontan cohort, most patients had reduced exercise capacity, largely due to cardiovascular dysfunction. However, “Super-Fontans” stood out as they had a higher anaerobic threshold illustrating their better physical condition. These findings highlight the role of regular physical activity in Fontan patients as a cornerstone for better functional capacity.

Abstract
Abstract
Introduction
The coronary sinus Reducer device (CSRD) emerged as a complementary therapy in patients with severe angina refractory to optimal medical therapy and not amenable to revascularization. Our aim was to assess the safety and efficacy of the CSRD in a real-world setting.
Methods
Twenty-six patients with refractory angina (RA), evidence of myocardial ischemia attributable to the left coronary artery unsuitable for revascularization were treated with the CSRD at two centres between May 2017 and July 2019. Safety endpoints were procedural success and complications. Efficacy endpoints, assessed at 6-month follow-up, were a reduction in CCS class, improvement in quality of life (QoL) assessed using the short version of the Seattle Angina Questionnaire (SAQ-7) and reduction in anti-anginal therapy.
Results
Twenty-three patients had end-stage CAD without revascularization targets and 3 patients had microvascular disease without epicardial stenosis. Procedural success was achieved 23 patients, with 2 device/procedural-related complications and one anatomically-related failure to deliver the device. Ultimately 25 patients implanted the device and entered the efficacy analysis. Eighteen patients (75.0%) had at least 1 reduction in CCS class, 41.7% had at least 2 class reductions, and 16.7% became asymptomatic, with a mean reduction of CCS class of 1.3±0.2 (p=0.001) at 6-month follow-up. All SAQ-7 domains improved, namely physical limitation (p=0.001), angina frequency (p=0.005) and QoL (p=0.006). There was a mean reduction of anti-ischemic drugs from 3.4±1.1 to 2.9±1.2 (p=0.010).
Conclusion
In this real-world, multicentric experience, implantation of the CSRD was associated with improvement of angina and QoL in patients with RA.

Abstract
Abstract
Background and aim
Standard single antiplatelet regimen (SAPT) is currently recommended before invasive risk stratification in non-ST elevation acute coronary syndromes (NSTE-ACS). However, there are subsets in whom dual antiplatelet therapy (DAPT) may be more protective according to the coronary anatomy and revascularization strategy. We aimed to identify pre-procedural predictors of coronary artery complexity that may be helpful in selecting an individualized antiplatelet regimen.
Methodology
Retrospective single-center study including patients with NSTE-ACS performing coronary angiography between January 2020 and July 2021. Clinical variables and classical NSTE-ACS risk scores (TIMI, GRACE and HEART) were captured and SYNTAX 1 score was calculated. Patients were divided into low (0–22), moderate (23–32) and high (≥33) SYNTAX score. Multivariate logistic regression analysis was performed to determine predictors of anatomical complexity (defined as significant left main disease [stenosis ≥50%] or SYNTAX ≥33).
Results
A total of 448 patients were included (mean age 67±13 years; 74% males; 85% with NSTE-myocardial infarction). Overall, 350 (78%), 63 (14%) and 35 (8%) patients had a low, moderate or high-SYNTAX score, respectively. Thirty-one (7%) patients had significant left main disease.
At multivariate analysis (adjusted for age, diabetes, renal function, GRACE and TIMI scores), the HEART score (hazard ratio 2.3, 95% confidence interval 1.5–3.3, p<0.001) predicted a high anatomical complexity. When performing ROC curve analysis, the HEART score had a high discriminative ability in identifying those with complex coronary anatomy (area under the curve 0.79, 95% CI 0.72–0.86, p<0.001) (Figure 1) – a score >7 showed a sensitivity of 76% and specificity of 75% in identifying such patients.
Conclusion
In this cohort of NSTE-ACS patients, the HEART score was an independent predictors of complex coronary anatomies. These results suggest that those with high (>7) HEART score may merit from SAPT as opposed to DAPT, given the high probability of complex lesions amenable to CABG.

Abstract
Background
Femoral access is considered the gold standard for transcatheter aortic valve implantation (TAVI). However, this route might be precluded due to the presence of tortuosity, small vessel diameter and/or peripheral artery disease. We aimed to investigate TAVI through an alternative access (AA), focusing on the selection criteria and clinical outcomes compared to the femoral route (TF).
Methods
We conducted an all-comers longitudinal single-centre prospective registry in whom a TAVI was performed. The feasibility, safety and efficacy of TAVI by means of an access route other than standard TF was assessed, according to the VARC-2 criteria. The prospective surgical criteria used at our institution to accept an AA route were: a) TF deemed inappropriate; b) acceptable haemorrhagic risk; c) acceptable general anaesthesia risk; and d) adequate anatomy and diameter within acceptable range (subclavian, axillar, transaortic) or e) age <85 years and non-frail patient (transapical). The primary endpoint was all-cause death at 1-year.
Results
From 2008 to 2018, there were 548 patients submitted to TAVI [median age 84 (79–87) years, males 45.4%]. An AA route was used in 100 patients (79 trans-apical, 9 trans-aortic, and 12 trans-subclavian), with a decreasing rate over follow-up (−11% per year). Compared to TF, these patients were younger [80 (77–84) vs. 85 (80–87) years; p<0.001) with a similar baseline surgical risk as per EuroSCORE II [5.1 (3.3–9.0) vs. 4.7 (3.3–7.0); p=0.410). AA patients presented a higher burden of atherosclerotic disease, namely coronary (54.0 vs. 41.3%; p<0.001) and peripheral artery disease (35.0 vs. 16.5%, p<0.001) despite a lower number of other comorbidities (e.g. glomerular filtration rate <50mL/min: 53.1 vs. 64.8%; p=0.030). Left ventricular ejection fraction (56±13 vs 55±12%; p=0.203) and aortic stenosis severity (e.g. valve area: 0.70±0.19 vs. 0.67±0.18cm2; p=0.302) were similar between groups. Haemorrhagic events (minor or major) following TAVI were less often documented in the AA group (11.0 vs 21.7%; p=0.015), contrasting with de novo atrial fibrillation (18.5 vs 7.6%; p=0.048). Overall, 67 patients met the primary endpoint (18.8 vs 16.2%; p=0.584). After adjusted multivariate analysis, the independent predictors of one-year mortality did not include the TAVI access route.
Conclusion
In the first 10 years of experience, 1 in every 6 patients was treated with a TAVI by means of an AA, most often trans-apically initially and, nowadays, via a trans-subclavian approach. The use of meticulous prospective selection criteria seems to explain the one-year similar results, regardless of the access route.

Abstract
Abstract
Introduction
Recently during the COVID-19 pandemic there was a general belief in a reduction of hospital admissions due to non-infectious causes, namely cardiovascular diseases.
Objectives
To evaluate the impact of the pandemic in the admissions by ST elevation acute myocardial infarction (STEMI), during the first pandemic wave.
Methods
Multicentric and retrospective analysis of consecutive patients presenting in two Portuguese hospital centers with STEMI in two sequential periods – P1 (1st March to 30th April) and P2 (1st May to 30th June). A comparison of patient's clinical and hospital outcomes data was performed between the year 2020 and 2017 to 2019 for both periods.
Results
A total of 347 consecutive STEMI patients were included in this study. The patient's baseline characteristics and cardiovascular risk factors were similar across the considered periods. During P1 of 2020, in comparison with previous years, a reduction in the number of STEMI patients was observed (26.0±4.2 vs 16.5±4.9 cases per month; p=0.033), contrary to what was observed during P2 (19.5±0.7 vs 20.5±0.7 cases per month; p=0.500). Percutaneous coronary interventions in the setting of failed thrombolysis were more frequent (1.9% vs 9.1%; p=0.033). A global trend in longer delays in time-key bundles of STEMI care was noted, namely pain to first medical contact, door to needle, door to wire crossing and symptoms to wire crossing times, however without statistical significance. Mortality rate was six-fold higher during P1 comparing to previous years (1.9% vs 12.1%; p=0.005), and also an increase in the number of mechanical complications (0.0% vs 3.0%; p=0.029) was observed.
Conclusions
During the first COVID-19 pandemic wave there were fewer patients presenting with STEMI at catheterization laboratory for coronary angioplasty. These patients presented more mechanical complications and higher mortality rates.

Abstract
Abstract
Introduction
Approximately half of transcatheter aortic valve implantaton (TAVI) candidates have coronary artery disease (CAD). Controversial results have been reported regarding the effect of the presence/severity of CAD and its management on clinical outcomes post-TAVI.
Aim
To describe the presence, extension, severityand management of CAD pre-TAVIand to evaluate its impact on 2-yearmortality in areal world all comers population.
Methods and population
Single centre retrospective analysis from a prospectively collected institutional registry (VCROSS) including 517 patients that underwent TAVI for severe aortic stenosis between January 2009 and December 2018. Patients who underwent pre TAVI CA in the context of ACS or at other institution were excluded n=138. Ultimately 380 entered the analysis. Obstructive CAD was defined as stenosis >50% in in major epicardial vessels (>2.5 mm). The total number of major epicardial with obstructive CAD was reported as was assessed the number of those left untreated. Univariate analysis was performed to assess 1) differences between patients with or without CAD and between those with significant CAD who have or have not undergone PCI, 2) variables associated with 2-year mortality. Binary logistic regression was performed to identify independent predictors of 2-year mortality including the presence of significant CAD and the type of management.
Results
A total of 380 patients were included, 55.3% male with an average age of 83YO (±6.3), mean Euroscore II of 4.35. 76 had previous coronary artery bypassgrafting (CABG) and 136 had previous PCI (43 had both). 55 patients (14.4%) presented with normal coronary arteries, 120 (31.6%) with non-obstructive CAD and 205 (54%) with obstructive CAD. Out of the latter, 112 (29.5%) underwent PCI. Statistically significant differences were found between obstructive CAD vs non-obstructive patients in terms of age, previous history of ICP and CABG. In the subgroup population with obstructive CAD, no statistically significant differences was found in the PCI vs non PCI group, apart from previous history of ICP and CABG – Figure 1. Diabetes mellitus, previous history of percutaneous coronary intervention (PCI) and reduced ejection fraction (rEF – defined has <50% echocardiographically) had a negative prognosticimpact in the 2 year mortality of the 380 patients. 2-year mortality was 14,5% (55 patients).The presence and management of CAD pre TAVI had no impact in 2-year mortality, when accounting for the differences in previous ICP history, CABG, age, and rEF.
Conclusion
The presence and type of management of obstructive CAD in this real world all comers registry did not impact the prognosis at 2 years.

Abstract
Introduction
New evidence on the role of myocardial revascularization in stable ischemic heart disease (SIHD), recently presented, showed that revascularization guided by the presence of moderate-to severe ischemia relieves angina more effectively than optimal medical therapy (OMT), without a significant benefit in hard clinical endpoints.
Aim
To assess the representativeness of the ISCHEMIA trial in a real-world population and compare management strategies between patients who fulfill the eligibility criteria of the trial (Group 1, G1) and those who do not (Group 2, G2).
Methods and population
Single centre retrospective analysis including all consecutive patients referred to coronary angiography (CA) for SIHD from January 2018 to December 2019. Patients were stratified in two groups (G1 and G2) according to the ISCHEMIA trial inclusion and exclusion criteria. G1 was compared with G2 and with a subset of G2 with obstructive coronary artery disease (CAD), defined as ≥70% luminal stenosis in at least one coronary artery or >50% for the left main.
Results
A total of 1020 patients underwent CA, of whom only 124 (12.2%) would have been eligible for the ISCHEMIA trial (G1). Overall, there were no significant differences in baseline characteristics between the two groups. G1 patients had more extensive and severe disease, presenting more frequently with proximal left anterior descending (LAD) involvement (26.6% vs 10.4%; p<0.001), two vessel disease without proximal LAD stenosis (23.4% vs 10.3%; p<0.001) and three vessel disease (18.5% vs 5.9%; p<0.001). These patients had higher rates of revascularization, both CABG (25.8% vs 10.8%, p<0.001) and PCI (56.5% vs 39.5%, p<0.001). However, when comparing G1 with the subset of G2 patients with obstructive CAD, G1 patients had higher rates of CABG (26.8% vs 17.8%, p=0.034) but there were no differences on the rates of PCI (58.0% vs 56.9%, p=0.916).
Conclusions
Patients included in the ISCHEMIA trial are underrepresented in a real-world population of SIHD patients referred to coronary angiography. PCI rates were similar among patients with at least one significant coronary artery stenosis, regardless of previous evidence or severity of ischemia. Our findings underline the need for further refinement in criteria for revascularization in SIHD.

Abstract
Abstract
Introduction
The evolution of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) techniques made the choice of the optimal revascularization strategy of unprotected left main coronary disease (ULMD) challenging. Scoring systems are useful tools for the decision-making process and for risk stratification.
Purpose
To evaluate 1) the performance of the SYNTAX score I (SSI) and II (SSII) and Euroscore II (EII) in risk stratification and 2) the outcome predictors of patients (pts) with ULMD, according to the treatment strategy chosen (PCI or CABG).
Methods
Retrospective single centre cohort study of 440 consecutive pts (age 68±11 years; 76.6% male) with significant ULMD (defined as left main coronary artery stenosis >50%, with no patent arterial or venous bypass graft to left anterior descending artery), who were submitted to PCI (n=135) or CABG (n=307), between January 2006 and December 2018. Median follow-up (FU) was 4.0±1.8 years.
The primary outcome was a composite of cardiovascular (CV) death, non-fatal myocardial infarction (MI) and target lesion revascularization (TLR).
Results
During the FU period, there were 112 (25.5%) CV deaths, 26 (5,9%) non-fatal MI and 53 (12.0%) TLR.
Multivariate analysis of pts submitted to PCI showed that SSII and anatomical complete revascularization were independent predictors of the primary outcome (HR 1.045, CI 1.015–1.075, p=0.003 and HR 3,014, CI 1.655–5.489, p<0.0001, respectively). The 63 pts submitted to PCI, who had a SSII favoring CABG, had slightly more adverse events (42.9% vs 41.7%, p=0.889).
In the CABG cohort, only SSII was an independent predictor of the outcome by multivariate analysis (HR 1.061, CI 1.035–1.086, p<0.0001).
The ROC curve analysis for all cohort presented no discriminative capacity for SSI (AUC 0.538, CI 0.482–0.593, p=0.186) and a weak discrimination for SSII (AUC 0.659, CI 0.605–0.713, p<0.0001) and EII (AUC 0.653, CI 0.599–0.707, p<0.0001; Figure 1). The difference between SSII and EII was not statistically significant (DeLong test p=0.828). Similar results were found when analysing the CAGB group, however, in PCI cohort, SII and EII showed an acceptable discriminative capacity (AUC 0.722, CI 0.636–0.809, p<0.0001 and AUC 0.700, CI 0.610–0.791, p<0.0001, respectively).
Conclusion
In a real-world ULMD population, the most common risk scores, mainly those integrating anatomical and clinical features, presented a very modest role in the risk stratification, both in chronic and acute coronary syndromes. However, in pts with ULMD submitted to PCI, those risk scores had a more significant role in the risk stratification of these pts.

Abstract
The development of new surface designs to enhance the integration process between surgically placed implants and biological tissues remains a challenge for the scientific community. In this way and trying to overcome this issue, in this work, laser technology was explored to produce novel textures on the surface of green zirconia compacts produced by cold pressing technique. Two strategies regarding line design (8 and 16 lines design) and different laser parameters (laser power and number of laser passages) were explored to assess their influence on geometry and depth of created textures. The produced textures were evaluated with Scanning Electron Microscopy (SEM) and it was observed that well-defined textured surfaces with regular geometric features (cavities or pillars) were obtained by laser combining different strategies lines design and parameters. The potential of proposed textures was also evaluated regarding surface wettability, friction performance (static and dynamic coefficient of friction evolution) against bone, aging resistance and flexural strength. Results demonstrated that all the produced textures display a super hydrophilic or hydrophilic behavior. Regarding the friction behavior, it was experimentally observed a high initial static coefficient of friction (COF) for all produced textures. Concerning the aging resistance, all the textured surfaces revealed a low monoclinic content, less than 25% after 5 h of hydrothermal aging. The flexural strength results showed that the mechanical resistance of zirconia was not significantly compromised with the laser action. Based on the obtained results, it is possible to prove that the processing route used for manufacturing the new and different surface designs (cold pressing technique followed by laser texturing) showed to be particularly effective for the production of zirconia implants with customized surface designs according to the properties required in a specific application. These new surface designs besides to enhance the surface wettability and also to improve the fixation at the initial moment of the implantation, do not significantly compromise the resistance to aging and the mechanical performance of zirconia. Hence, a positive impact on the long-term performance of the zirconia implants may be expected with the proposed novel laser textured surface designs.

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).

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
Abstract
Aim
High-sensitivity troponin assays (HST) entered the clinical arena to facilitate exclusion of ACS in the emergency department (ER) in patients presenting with chest pain. Due to its higher sensitivity there is the potential for an overestimation of the diagnosis of NSTEMI, and possibly ACS overall. We assessed the impact of HST in the classification of ACS (NSTEMI vs UA) and its ability to predict obstructive coronary disease (CAD), in a population of pts referred to coronary angiography (ICA).
Methods
Retrospective analysis of 1844 pts with suspected NSTEMI or UA referred for ICA from a single ER between Feb 2013 and Nov 2018. Standard Troponin-I was used until Feb 2016 and HST thereafter. The characteristics of UA and NSTEMI pts before and after the introduction of HST were compared. Multivariate binary logistic regression models were used to access the association of different troponin assays with CAD (>50% for LM and >70% for the remaining). Sensitivity, specificity, NPV and PPV for angiographic CAD were also determined.
Results
The relative proportion of patients with UA and NSTEMI was similar between study periods: 31% vs 29% and 69% vs 71%, respectively (p=0.3). Clinical and angiographic characteristics did not differ in UA pts before and after the use of HST. NSTEMI patients in the HST era were less frequently women (39% vs 32%, p=0.026), had higher creatinine (0.93 IQR 0.75–1.3 vs 1.0 IQR 0.82–1.38), higher number of lesions (2 IQR 1–4 vs 3 IQR 1–4) and a lower rate of normal coronary arteries (10.5% vs 3.9%, p<0.001). The prevalence of significant CAD in this population, before and after HST, was 65% and 73%, respectively (p=0.001). However, when clinically relevant characteristics and judgement were accounted for, both standard troponin (OR 0.99, 95% CI 0.99–1.01) and HST (1.0, 95% CI 1.0–1.0) were poor predictors of significant CAD. Sensitivity was 69% vs 72%, specificity 30% vs 30%, PPV 65% vs 73% and NNP 34% vs 28%, respectively. Finally, rates of percutaneous intervention did not differ between the two periods (30% vs 33.5%, p=0.157), nor between ACS types within each period.
CAD/PCI in ACS within each period
Conclusion
The introduction of HST did not result in an increase of the diagnosis of NSTEM vs UA, suggesting that clinical judgment remains an important determinant of the diagnosis of ACS. Also there was no evidence of an increase in PCI rates, despite worse CAD severity in NSTEMI patients.

Abstract
The development of dental restorative materials that mimic tooth-like properties provided by graded structures, aesthetics and properties such as strength, damping capacity and the ability for a continuous remodeling according to the biomechanical solicitation is a great challenge. In this work, damping capacity and dynamic Young's modulus of Y-TZP/porcelain composites for all-ceramic dental restorations were studied. These mechanical properties were assessed by dynamic mechanical analyses (DMA) at frequencies of 1, 5 and 10 Hz, over a temperature ranging from 0 to 60 °C, simulating extreme conditions when a cold or hot drink is experienced. The results showed that porcelain and porcelain-matrix composites exhibited higher damping capacity while Y-TZP and Y-TZP-matrix composites presented higher dynamic Young's modulus. Furthermore, while damping capacity is strongly influenced by the temperature, no significant difference in dynamic Young's modulus was found. For both damping and modulus properties, no significant influence of frequency was found for the tested materials. Based on the obtained results and also on the known advantages of the graded Y-TZP/porcelain structures over traditional bi-layer solutions (e.g., improved bending strength, enhanced mechanical and thermal stress distribution), a novel design of all-ceramic restoration with damping capacity has been proposed at the end of this study. A positive impact on the long-term performance of these all-ceramic restorations may be expected.

Abstract
Background What constitutes respectful maternity care (RMC) operationally in research and programme implementation is often variable. Objectives To develop a conceptualisation of RMC. Search strategy Key databases, including PubMed, CINAHL, EMBASE, Global Health Library, grey literature, and reference lists of relevant studies. Selection criteria Primary qualitative studies focusing on care occurring during labour, childbirth, and/or immediately postpartum in health facilities, without any restrictions on locations or publication date. Data collection and analysis A combined inductive and deductive approach was used to synthesise the data; the GRADE CERQual approach was used to assess the level of confidence in review findings. Main results Sixty‐seven studies from 32 countries met our inclusion criteria. Twelve domains of RMC were synthesised: being free from harm and mistreatment; maintaining privacy and confidentiality; preserving women's dignity; prospective provision of information and seeking of informed consent; ensuring continuous access to family and community support; enhancing quality of physical environment and resources; providing equitable maternity care; engaging with effective communication; respecting women's choices that strengthen their capabilities to give birth; availability of competent and motivated human resources; provision of efficient and effective care; and continuity of care. Globally, women's perspectives of what constitutes RMC are quite consistent. Conclusions This review presents an evidence‐based typology of RMC in health facilities globally, and demonstrates that the concept is broader than a reduction of disrespectful care or mistreatment of women during childbirth. Innovative approaches should be developed and tested to integrate RMC as a routine component of quality maternal and newborn care programmes.

Abstract
Bovine tuberculosis (bTB) is a worldwide zoonotic disease of domestic and wild animals. Eradication has proved elusive in those countries with intensive national programmes but with ongoing transmission between wildlife and cattle. In Portugal, a high-risk area for bTB was defined and specific measures implemented to assess and minimize the risk from wildlife. Data from the 2011 to 2014 hunting seasons for red deer (Cervus elaphus) and wild boar (Sus scrofa) were analysed with bovine demographic and bTB information to assess factors that determined the occurrence and distribution of bTB in both species. The likelihood of bTB-like lesions in wild boar was positively associated with density of red deer, wild boar and cattle, while for red deer, only their density and age were significant factors. The likelihood of Mycobacterium bovis isolation in wild boar was associated with density of cattle and red deer and also with the anatomical location of lesions, while for red deer, none of the variables tested were statistically significant. Our results suggest that, in the study area, the role of red deer and wild boar may be different from the one previously suggested by other authors for the Iberian Peninsula, as red deer may be the driving force behind M. bovis transmission to wild boar. These findings may assist the official services and game managing bodies for the management of hunting zones, what could also impact the success of the bTB eradication programme.

Abstract
The viability of the currently unculturable fungal pathogen Lacazia loboi can be determined by means of fluorescein diacetate-ethidium bromide (FD-EB) staining. This technique can be used in experimental study of the mycosis, in attempts to cultivate the fungus and in attempts to gauge the success of therapies. In the present study, the potential applications of FD-EB vital staining were studied using a proposed murine experimental model of lobomycosis. BALB/c mice were inoculated in the footpads with an L. loboi suspension that appeared in FD-EB staining to have lost viability after being held for 15 days at room temperature, whereas a control group of mice was inoculated with apparently viable fungi. The animals were killed after 1, 2, 4, 6, 8, 11 and 13 months. Both inoculated footpads were excised, one for determination of viability and the other for histological examination. In the group injected with nonviable material, no active infection was noted; inoculation sites showed small quantities of macrophage-laden infiltrate and no viable fungal cells. In the control group, the infection progressed with exuberant infiltrates surrounding copious fungal growth, most of which consisted of cells staining as viable in FD-EB. These results suggest that the FD-EB vital staining is a sensitive and specific method that can reliably be used for viability determination in L. loboi.

Abstract
Long-term maintenance of Lacazia loboi in the laboratory has not been reported. We report here the use BALB/c mice to maintain the Lacazia loboi for extended period of time. Eight to ten week-old mice were inoculated intradermally in both hind footpads with a fungal suspension from a macerated footpad obtained from an original mouse previously infected with the fungi and sacrificed 8 months after inoculation. The inoculated animals were sacrificed at different time intervals, footpads were excised, the right one was submitted to histopathological examination and the left one was macerated in sterile saline for fungal count and viability index determination. The inoculated animals presented the histopathological picture identical to the mice previously inoculated with material from human lesion. Granulomatous infiltrates with predominance of macrophages and giant cells were observed. The granulomas evolved progressively as observed in the different times of sacrifice. After 7 months of inoculation, macroscopic lesions were observed, and the number of fungi obtained from macerated footpads was higher than the number of inoculated fungi. The pattern of lesion development was similar to what was observed in animals infected with a fungal suspension obtained from a human lesion. Considering the histopathological findings, the clinical manifestations, and the finding of a higher number of fungi obtained than the inoculated into footpads of each mice, we believe the BALB/c mice strain is as an excellent way to maintain L. loboi in laboratory. Moreover, even after serial passages of the fungi, the granulomatous lesions are reproduced consistently in laboratory conditions.

Abstract
In a previous study, the authors inoculated Swiss mice with Lacazia loboi (L. loboi) and succeeded in maintaining a granulomatous infiltrate and viable fungal cells up to one year and six months after inoculation. Considering the experimental work on paracoccidioidomycosis, 0.03 ml of a fungal suspension obtained from a biopsy of a Jorge Lobo's Disease patient were inoculated into both hind foot pads of 32 six week-old BALB/c mice of both sexes. The animals were sacrificed 1, 4, 7 and 10 months post inoculation. The suspension contained 1.3 x 10(6) fungi/ml and presented 38% viability. Seven months after inoculation, most of the animals presented profuse infiltrates consisting of isolated histiocytes, foreign body and Langhans' giant cells and a large number of fungi, most of them viable. Emergence of macroscopic lesions was observed during the 8th month. Based on fungal count, viability index before and after inoculation, presence of macroscopic lesions and histopathological findings similar to the findings in humans, the authors believe that BALB/c mice may be a good experimental model to study Jorge Lobo's Disease, mainly regarding therapeutic evaluation.

Abstract
Sixty-four isogenic Swiss mice were intradermically inoculated in both hind foot pads. The inocula, consisting of fungal suspensions from biopsies obtained from Jorge Lobo's Disease patients, had the total number of fungi and the viability index determined using a Neubauer chamber and the fluorescein diacetate-ethidium bromide technique (FD-EB), respectively. The animals were sacrificed at times ranging from ten days to eighteen months after inoculation. The cellular infiltrate, mainly consisting of macrophages containing fungi, increased progressively up to end of the study; however, no macroscopic alterations were observed in the inoculated feet. After nine months, small numbers of Langhans' giant cells started to appear in the infiltrate. A considerable number of fungi was observed at the end of the experimental period, but only a few were viable when stained by the FD-EB technique. This fact suggests that there is a multiplication of fungal cells, which are destroyed by the macrophages but remain in the tissue for a long time due perhaps to the difficulties in their elimination. These findings led us to conclude that in spite of the maintenance of the infection in these animals, Swiss mice cannot be considered an ideal model to study Jorge Lobo's Disease. However, the authors call attention to the possibility of other mouse strains being more susceptible to Paracoccidioides loboi.
