Abstract
PURPOSE The objective of this double-blind, split-mouth, randomized clinical trial was to evaluate the color match of a single-shade composite resin Admira Fusion X-tra in comparison with a multi-shade composite resin Admira Fusion in non-carious cervical lesion restorations (NCCLs). METHODS AND MATERIALS One hundred and twenty restorations were performed on NCCLs with two restorative materials (n=60). After prophylaxis, the teeth were isolated with a rubber dam, and one universal adhesive was applied in the selective enamel etching strategy. For both groups, the restorations were inserted incrementally and light-cured. The values of the coordinates L*, a*, and b* in the cervical third before vs after the restorations and cervical vs middle third after the restorations were evaluated using a digital spectrophotometer after the coordinate values were used to calculate the CIEDE (ΔE00). The restorations were evaluated at baseline and after 7 days of clinical performance according to the FDI criteria. Statistical analysis was performed using the Chi-square test for all parameters. Color change was analyzed by Student t-test for paired samples (α=0.05). RESULTS All restorations were evaluated after 7 days. Regarding the color measurement, no significant difference was observed when Admira Fusion was compared to Admira Fusion X-tra for any of the comparisons performed (p>0.05). However, the values of ΔE00 in the cervical third before vs after the restorations were higher when compared with ΔE00 observed when the cervical vs middle third after restorations were compared. All restorations received the score "clinically very good" after 7 days for all outcomes, including the subjective color match, when evaluated for FDI criterion. CONCLUSIONS The single-shade composite resin used achieves the same color match when compared to a multi-shade composite resin after 7 days in NCCLs.

Abstract
Software programming is an acquired evolutionary skill originating from consolidated cognitive functions (i.e., attentive, logical, coordination, mathematic calculation, and language comprehension), but the underlying neurophysiological processes are still not completely known. In the present study, we investigated and compared the brain activities supporting realistic programming, text and code reading tasks, analyzing Electroencephalographic (EEG) signals acquired from 11 experienced programmers. Multichannel spectral analysis and a phase-based effective connectivity study were carried out. Our results highlighted that both realistic programming and reading tasks are supported by modulations of the Theta fronto-parietal network, in which parietal areas behave as sources of information, while frontal areas behave as receivers. Nevertheless, during realistic programming, both an increase in Theta power and changes in network topology emerged, suggesting a task-related adaptation of the supporting network system. This reorganization mainly regarded the parietal area, which assumes a prominent role, increasing its hub functioning and its connectivity in the network in terms of centrality and degree.

Abstract
Abstract
Introduction
Beta-blockers (BB) are recommended in patients with previous acute myocardial infarction (AMI), aiming to reduce morbidity and mortality. Their benefit is greater in patients with associated left ventricular dysfunction. However, in patients with atrial fibrillation (AF) its prognostic benefit is controversial.
Purpose
To assess and compare the in-hospital and 1-year prognostic impact of BB prescription after acute coronary syndrome (ACS), in patients with previous or de novo AF, and in patients with sinus rhythm (SR).
Methods
This was a national multicentre retrospective study of patients hospitalized for ACS between October 2010 and December 2021. A total of 35279 patients was included, and divided in two groups according to the prescription or not of BB. Patients with previous history of ischemic heart disease (myocardial angina, AMI or coronary revascularization) or heart failure, as well as presenting in Killip class IV or submitted to coronary artery bypass graft during admission were excluded. The impact of BB prescription on in-hospital and 1 year mortality rates, in patients with AF versus SR, was compared.
Results
A total of 14906 patients was selected, 82.5% with and 17.5% without BB prescription. Most patients were in SR (90.2%), with 9.8% presenting previous or new-onset AF.
Patients without BB prescription were older (67±14 vs. 63±13 years) and had more comorbidities, namely valvular disease (2.3% vs. 1.2%, p<0.001) and chronic pulmonary obstructive disease (7.1% vs. 3.1%). The mean left ventricular ejection fraction was 53±13% in patients without BB prescription and 52±11 in the group with BB prescription (p<0.001). In-hospital and after discharge BB prescription was less frequent in AF patients (80.2% vs. 82.5% and 74.7% vs. 78.8%, respectively).
The in-hospital mortality rate was 2.2%, 1.3% in the BB group and 6.6% in patients without BB prescription (p<0.001). At 1 year, mortality rate increased to 5.1%.
BB prescription was associated with lower in-hospital mortality rate regardless of the rhythm, with an 81% risk reduction in SR (OR = 0.19, 95% CI 0.14–0.24) and 79% in AF patients (OR = 0.21, 95% CI 0.13–0.35). In a multivariate regression analysis, after adjusting for all the possible confounders, in-hospital BB prescription was associated with 70% of mortality risk (OR = 0.30, 95% CI 0.23–0.35).
Overall, after discharge BB prescription was associated with reduced 1-year mortality risk (HR = 0.57, 95% CI 0.44–0.73), although it didn't reach statistical significance in AF patients (p=0.413). Nevertheless, in a bivariate Cox regression, rhythm showed no impact on BB protective effect (p-interaction = 0.335). As expected, AF had a negative prognostic impact (HR = 3.85, 95% CI 2.66–5.02).
Conclusion
BB prescription was associated with reduced in-hospital and 1 year mortality rates. The prognostic benefit of BB therapy was equivalent in ACS patients in sinus rhythm and with previous or new-onset AF.

Abstract
Abstract
Introduction
Crusade score (CS) quantifies intrahospital major bleeding (IHMB) risk in patients admitted with acute coronary syndrome (ACS). Hemorrhagic risk after ACS increases with age, although, it's not considered in score estimation.
Purpose
Evaluate CS ability to predict IHBM risk according to different patient ages (higher or lower than 75 years) admitted with ACS diagnosis and submitted to double antiagreggation therapy with acetylsalicylic acid and Clopidogrel.
Methods
A retrospective study based on the Portuguese National Registry of ACS, including patients (pts) hospitalized with ACS and treated with double antiagreggation therapy with acetylsalicylic acid (AAS) and clopidogrel between October 2010 and January 2021 (n=8401). Were excluded patients submitted to coronary artery bypass grafting, with ticagrelor or prasugrel switch to clopidogrel during hospitalization.
Patients were divided into two groups according to their age (above or below 75 years) and then subdivided in 5 groups according to CS category of IHBM risk estimation: very low (CS ≤20, 3,1% risk predicted by the score), low (21 ≤ CS≤30, 5,5%), moderate (31 ≤ CS≤40, 8,6%), high (41 ≤ CS≤50, 11,9%) and very high risk (CS≥51, 19,5%). Then, the incidence of IHMB observed in each group during hospitalization (mean 5 days) was compared to the IHBM risk predicted by the CS.
Results
The IHMB rate was 1.78%, significantly lower than predicted by the Crusade score (7.1%, p<0.001). Bleeding rates in each group of patients (above or below 75 years and according to CS calculation are depicted in Figure 1. CS revealed more power to predict IHMB in the prespecified group of patients older than 75 years, than in the group of patients younger than 75 years (see Figure 2).
Conclusion
As shown in different literature, crusade score overestimate bleeding risk after ACS compared to real-life cohorts. Despite the same trend observed in our cohort of patients, in this retrospective study, CS revealed more power to predict IHMB in the prespecified group of patients older than 75 years, than in the group of patients younger than 75 years in patients submitted to double antiaggregation with AAS and clopidogrel.

Abstract
Abstract
Background
Obstructive sleep apnea (OSA) is a risk factor for development of atrial fibrillation (AF). Recent pacemakers have specific algorithms for detecting of OSA based on impedance measurement.
Purpose
The aim was to determine the burden of AF in patients with high respiratory disturbance index (RDI). It was also intended to determine if the onset of continuous positive airway pressure (CPAP) reduced the AF burden.
Methods
Retrospective observational study carried out through the analysis of the patient records. It included patients with pacemakers evaluated in an outpatient clinic during the first 8 months of 2018. All had the RDI algorithm. AF burden was assessed according to automatic mode switch (AMS) duration. The percentage of nights with an RDI>20/h was analysed to assess the risk of OSA.
Results
108 patients were included (mean age=70.3±9.0 years; 56.5% men). The most prevalent indication for cardiac pacing was atrioventricular node dysfunction (59.3%). The average percentage of nights with an RDI>20/h was 44.2%. The average follow-up (FU) period was 4.1 years.
Of all cardiovascular risk factors, diabetes mellitus was the only one associated with a higher incidence of AF at FU (p=0.044).
Considering just the patients with an RDI >20/h in more than 20% of nights (RDI20%), male gender was associated with higher rate of major adverse cardiovascular events [(acute myocardial infarction, stroke, acute heart failure and death) (p=0.019)].
Considering patients with AF prior to pacemaker implantation (n=34), 76% of patients had an RDI >20/h in more than 20% of nights (mean of 58.1%). 23 of these patients had long standing persistent AF at the end of FU (vs 17 at the beginnig of FU).
Considering patients who developed AF after pacemaker implantation (n=24), 58% of patients had an RDI>20/h in more than 20% of nights (mean of 45.3%). Most patients had paroxismal AF (83%).
Patients with prior paroxysmal AF or those who developed AF during FU (n=37) had a higher burden of AF at the end of FU when they had RDI >20/h in more than 50% of nights (mean burden of 24.66% vs 14.69%, p=0.005).
There was no statistically significant correlation between the percentage of nights with RDI >20/h and the Apnea Hypopnea Index (AHI) value. Patients who underwent polysomnography (n=30) had a mean AHI of 16/h (which corresponds to moderately severe OSA). 63% of patients who were referred from the pacemaker consultation to pneumology and performed polysomnography started CPAP.
CPAP use was not associated with a statistically significant reduction in any endpoints or AF burden.
Conclusion
A high RDI was associated with onset of de novo AF and higher AF burden in patients with paroxysmal AF. Thus, there is a rationale for early diagnosis and treatment of OSAS to prevent and reduce AF progression.
In this study, CPAP was not shown to significantly reduce this endpoint, probably due to reduced polysomnography and CPAP treatment.

Abstract
Abstract
Study question
Evaluate the influence of sperm selection according to the sorting technique, and its effects in clinical and laboratory parameters in IVF/PGT-A cycles.
Summary answer
Cycles that used microfluidic sperm selection device presented an increase in clinical pregnancy rates.
What is known already
A common genomic anomaly detected in subfertile men is the Sperm DNA fragmentation. It is resulted of a high concentation of free radicals produced causing oxidative stress in sperm cells. In order to achieve a normal embryonic development is necessary good spermatozoa with intact genetic material. In fact, embryonic quality parameters as lower fertilization, blastocyst formation and pregnancy rates has been related with Sperm DNA fragmentation increased cases. The microfluidic sperm selection device has been commercialized promising to select spermatozoa with a low level of DNA fragmentation and suggest a relationship between embryo quality, euploidy and pregnancy rates.
Study design, size, duration
A case-control study involving 494 IVF/PGT-A cycles that resulted in embryo biopsy between June, 2020 and November, 2021 at a Brazilian private practice unit (Instituto Ideia Fertil) were included in this analysis.
Participants/materials, setting, methods
All cycles that would perform PGT-A were splitted in two groups considering the sperm sorting technique: case - Microfluidic sperm selection device (245 cycles) and control - Density gradient centrifugation + swim-up (249 cycles) were included. The variables considered in this analysis were patient age, sperm concentration, fertilization, D3 top quality, blastocyst top quality, blastulation, ploidy and pregnancy rates. This data were analysed between groups and female age (until 37; 38-40 and over 41).
Main results and the role of chance
The mean age of the female and male patients found were 38.05 and 38.2 respectively and there was not statistically significant different between groups. Fertilization rate compared between case (72.4%) and control (76.5%) groups (p < 0.05) demonstrated statistically significant difference, but when stratified accordingly to the age, only the female age until 37 years old group showed significant difference (73.25%; 76.43%; p < 0.05). The variables analyzed as D3 Top Quality, Blastocyst Top Quality, blastulation and ploidy did not present difference (p = 0.552; 0.699; 0.378). The clinical pregnancy rate analyzed revealed in case group 65.33% and control 56.38% (p < 0.05), demonstrating statistically significant difference. When groups were splitted according to the female age (until 37 years old; 38-40 and over 41) the findings behaved in the same characteristics, increasing only the clinical pregnancy rate. The tests used was Mann-Whitney and Kruskal-wallis.
Limitations, reasons for caution
The DNA fragmentation test was not evaluated because not all patients had this test performed. Besides that, another parameter that will be analysed is live birth rate.
Wider implications of the findings
Microfluidic sperm sorting device made possible to select high quality spermatozoa according to motility, morphology, and low rates of fragmentation, showing the importance of having a good sperm in clinical pregnancy rate.

Genetic and morphological identification of filarial worm from Iberian hare in Portugal. Sci Rep 2022; 12:9310.

Abstract
The Iberian hare (Lepus granatensis) is an endemic species of the Iberian Peninsula and the only hare species found in Portugal, although also being present in some areas of Spain. The reduction of wild hare populations due to several ecological and sanitary factors, has been raising growing concerns in the recent years. Despite different helminth species were already described in Iberian hares in Portugal, to this date, no filarial worms have been identified in this species. Furthermore, only a few studies on lagomorphs' onchocercid worms are available, referring to other hosts species of hares and/or rabbits. In this study, we describe the presence of filarial worms in the blood vessels of two adult Iberian hares collected in 2019 in continental Portugal. Morphology and sequencing data from the 12S rRNA, coxI, 18S rRNA, myoHC, hsp70 and rbp1 genes, showed that the filaroid species were genetically related with Micipsella numidica. However, the extension of the genetic differences found with M. numidica suggests that the filaroids specimens under study belong to a new species, that we provisionally named Micipsella iberica n. sp.. The body location of this putative new parasite species and its physiological implications indicate that it may constitute a potential menace to the already fragile Iberian hare justifying, therefore, further investigation regarding the morphological characterization, prevalence and real clinical impact of this new parasite in hares.

Background
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Patients are often symptomatic leading to a reduction in quality of life. Recent studies suggests that early rhythm control therapy have a clinical benefit in patients with recently diagnosed AF.
Purpose
This study aims to evaluate outpatient with AF referred to an outpatient clinic to electrical Cardioversion. Besides that, the study aims to evaluate if outpatient referred from the emergency room had spontaneously reverted to sinus rhythm.
Material and Methods
Retrospective observational study carried out through the analysis of the clinical process. Clinical data were collected from AF patients evaluated in an outpatient clinic during the year of 2020. Statistical analysis was made using R software and RStudio.
Results
This study included 92 patients evaluated in an outpatient clinic and referred because paroxysmal, persistent and long standing AF to electrical cardioversion. Average age was 67.3 ± 10.1 years. 78 patients had atrial fibrillation and 14 patients had atrial flutter. Hypertension was the most prevalent risk factor (n=83; 79,3%), followed by dislipidemia (n=66; 71.7%), overweight (n=43; 46,7%), diabetes mellitus (n=27; 29.3%) and smoke (n=20; 21.7%). 15 patients had paroxysmal AF, 67 patients had persistent AF and 10 patients had long standing AF. CHA2DS2VASC median were 2,78 ± 1.66 and HASBLED median was 1,14 ± 0.94. The heart rate control were most frequently made with betablocker (n=78; 84.7%). 4 patients (4,3%) were medicated with digoxin and 3 patients with calcium channel blockers. 69 patients were forwarded from external consultant and 23 patients from the emergency room (ER). We verified that 12 patients (52,2%) were in sinus rhythm in admission of outpatient clinic and had spontaneously reversion to sinus rhythm. Mostly patients with paroxysmal AF were from the ER (80% of all patients, p<.001) and mostly patients with persistent and long standing AF were from external consultant (respectively 82% p<0.01 and 85% p<0,01). Symptoms improvement were evaluated by EHRA classification. Mostly patients had clinical improvement after electrical or spontaneously cardioversion (63%, p.0.02). The median EHRA score previous to CVE were "2" and after cardioversion were "1".
Conclusions
Risk factor control is the cornerstone of AF prevention. Control rhythm is important to improve clinical symptons related to AF. However, we can delay cardioversion in a recent acute episode in the emergency room. In our sample, it seems that AF with short natural story presents more in emergency room and the more chronic comes to our consultation.

Background
Behavioral and emotional factors may trigger cardiovascular events (CVE). Watching sports when there is an emotional connection between the supporters and the supportive team, is believed to be potentially associated with CVE. However, epidemiological studies have been inconsistent, with several studies showing an increase in CVE, while others reporting a protective effect.
Purpose
To assess the effect of watching sport events on the incidence of cardiovascular events.
Methods
Pubmed, and Embase were systematically searched to identify appropriate articles. Reference lists were then hand searched for additional relevant articles. To be included, articles had to assess the association between CVE and sport events supporters (adeptos). Pooled association measures, using random effects analysis, were calculated for mortality; arrhythmias; myocardial infarction (MI). Subgroup analysis was conducted based on gender. Publication bias and between-study heterogeneity were evaluated.
Results
There were nineteen studies included in the analysis. The pooled relative risks for mortality, arrhythmias and MI were 1.45(0.98-2.15; 95%CI; I2=70%; p=0.02); 1.31(0.98-1.77; 95%CI; I2=85%; p<0.01); 1.11(0.98-1.24; 95%CI; I2=91%; p<0.01) respectively (Figure 1A). The null association persisted in the subgroup analyses by gender for mortality (Figure 1B) as well as for MI and for the combined endpoint MI/stroke (non significant relative risks).
Conclusions
Overall this analysis suggests that watching sport events does not increase cardiovascular events regardless of gender.

Abstract
The objective of this experiment was to evaluate the effects of supplementing a rumen-protected source of Met, N-acetyl-l-methionine (NALM), on lactational performance and nitrogen metabolism in early- to mid-lactation dairy cows. Sixty multiparous Holstein dairy cows in early lactation (27 ± 4.3 d in milk, SD) were assigned to 4 treatments in a randomized complete block design. Cows were blocked by actual milk yield. Treatments were as follows: (1) no NALM (control); (2) 15 g/d of NALM (NALM15); (3) 30 g/d of NALM (NALM30); and (4) 45 g/d of NALM (NALM45). Diets were formulated using a Cornell Net Carbohydrate and Protein System (CNCPS) v.6.5 model software to meet or exceed nutritional requirements of lactating dairy cows producing 42 kg/d of milk and to undersupply metabolizable Met (control) or supply incremental amounts of NALM. The digestible Met (dMet) supply for control, NALM15, NALM30, and NALM45 were 54.7, 59.8, 64.7, and 72.2 g/d, respectively. The supply of dMet was 88, 94, 104, and 115% of dMet requirement for control, NALM15, NALM30, and NALM45, respectively. Milk yield data were collected, dry matter intake (DMI) was measured daily, and milk samples were collected twice per week for 22 wk. Blood, ruminal fluid, urine, and fecal samples were collected during the covariate period and during wk 4, 8, and 16. Data were analyzed using the GLIMMIX procedure of SAS (SAS Institute) using covariates in the model for all variables except body weight. Linear, quadratic, and cubic contrasts were also tested. Treatments did not affect DMI, milk yield, and milk component concentration and yield; however, feed efficiency expressed as milk yield per DMI and 3.5% fat-corrected milk per DMI were quadratically affected, with greater response observed for NALM15 and NALM30 compared with control. Acetate proportion linearly increased, whereas propionate proportion linearly decreased with NALM supplementation. Blood urea nitrogen linearly decreased with NALM supplementation. Total plasma essential AA concentrations were quadratically affected, as greater values were observed for control and NALM45 than other treatments. Plasma Met concentration was quadratically affected as lower levels were observed with NALM15, whereas Met concentrations increased with NALM45 compared with control. Nitrogen utilization efficiency and apparent total-tract nutrient digestibility were not affected by treatment. Supplementation of NALM at 15 or 30 g/head per day resulted in the greatest improvements in feed efficiency without affecting N metabolism of early- to mid-lactation dairy cows.

Abstract
Abstract
Background
In ST-segment elevation myocardial infarction (STEMI), time delay between symptom onset and treatment is critical to improve outcome. The expected transport delay between patient location and percutaneous coronary intervention (PCI) centre is paramount for choosing the adequate reperfusion therapy. The “Centre” region of Portugal has heterogeneity in PCI assess due to geographical reasons.
Purpose
We aimed to explore time delays between regions using process mining (PM) tools.
Methods
We retrospectively assessed the Portuguese Registry of Acute Coronary Syndromes for patients with STEMI from October 2010 to September 2019, collecting information on geographical area of symptom onset, reperfusion option, and in-hospital mortality. We used a PM toolkit (PM4H – PMApp Version) to build two models (one national and one regional) that represent the flow of patients in a healthcare system, enhancing time differences between groups. One-way analysis of variance was employed for the global comparison of study variables between groups and post hoc analysis with Bonferroni correction was used for multiple comparisons.
Results
Overall, 8956 patients (75% male, 48% from 51 to 70 years) were included in the national model (Fig. 1A), in which primary PCI was the treatment of choice (73%), with the median time between admission and primary PCI <120 minutes in every region; “Lisboa” and “Centro” had the longest delays, (orange arrows). Fibrinolysis was performed in 4.5%, with a median time delay <1 hour in every region. In-hospital mortality was 5%, significantly higher for those without reperfusion therapy compared to PCI and fibrinolysis (10% vs. 4% vs. 4%, P<0.001). In the regional model (Fig. 1B) corresponding to the “Centre” region of Portugal divided by districts (n=773, 74% male, 47% from 51 to 70 years), only 61% had primary PCI, with “Guarda” (05:04) and “Castelo Branco” (06:50) showing significant longer delays between diagnosis and reperfusion treatment (orange and red arrows, respectively) than “Coimbra” (01:19) (green arrow); only 15% of patients from “Castelo Branco” had primary PCI. Fibrinolysis was chosen in 10% of patients, mostly in “Castelo Branco” (53%), followed by “Guarda” (30%), with a median time delay of 39 and 48 minutes, respectively. Regarding mortality, PCI and fibrinolysis groups had similar death rates while those patients without reperfusion had higher mortality (5% vs. 3% vs. 13%, P=0.001).
Conclusion
Process mining tools help to understand referencing networks visually, easily highlighting inefficiencies and potential needs for improvement. The “Centre” region of Portugal has lower rates and longer delay to primary PCI partially due to the geographical reasons, with worse outcomes in remote regions. The implementation of a new PCI centre in one of these districts, is critical to offer timely first-line treatment to their population.

Abstract
Abstract
Background
Acute coronary syndrome (ACS) has a higher incidence in middle-aged and elderly patients but 2% to 6% of ACS cases occur in people younger than 45 years of age (Y). Younger patients have different clinical characteristics when compared to older patients. Acute chest pain fast track led to a reduction in the time required for the diagnosis of acute coronary syndromes, particularly those with ST segment elevation (STEMI).
Aim
This study aims to assess the differences in risk factors and clinical characteristics between young and older ACS patients. Besides that, we try to determine if the benefits of acute chest pain fast track have extended to this younger population.
Material and methods
Retrospective observational study carried out through the analysis of the clinical process. Clinical data were collected from ACS patients under 45Y from 2010 to 2019 and from ACS patients over 45Y from 2010 to 2012. Statistical analysis was made using R software and RStudio.
Results
This study included 93 patients with ACS under 45Y and 172 patients with ACS over 45Y. A total of 265 patients were included. The male gender was predominant in both groups but with a higher prevalence in the younger ones (88% vs 73%, p<0,005). The prevalence of hypertension was higher in older ACS patients but the younger ones had more overweight (39.8% vs 17.4%, p<0,001), smoking history (84.9% vs 38.4%, p<0,001) and family history of sudden death (25.8% vs 5.8%, p<0,01). Diabetes had no statistical difference. Dyslipidemia as previous known risk factor had no statistical difference but LDL was higher in patients with less than 45Y (147.2 vs 120.7 mg/dL, p<0,001). STEMI were tendentially more prevalent in patients under 45Y (55.9% vs 44.8%, p 0.09). The anterior wall was the most frequently involved in both groups (52% vs 63%, p 0.28), followed by the inferior wall (42% vs 36%). Accordantly, anterior descending artery was the artery most frequently involved in both groups (44.1% vs 48.3%), followed by right coronary artery (24.7 vs 26.7%). STEMI patients under 45Y were submitted to an emergent coronary angiography in 89% of cases and STEMI patients over than 45Y were submitted in 70.1% of cases. Particularly for patients under 45Y, all STEMI patients were submitted to an emergent coronary angiography after 2014, which emphasis the importance of acute chest pain fast track in the emergency room. Finally, ACS patients under 45Y were less submitted to percutaneous coronary angiography compared to patients over 45Y (15.1% vs 4.7%, p<0,001).
Conclusions
Cardiovascular risk factors differ accordingly the age of ACS patients. Younger patients had more overweight and smoking history. They probably have alternative pathophysiologic mechanisms that explain differences in percutaneous coronary angiography. Acute chest pain fast track had an important role reducing morbimortality related to ACS by reducing the time until STEMI diagnose.

Abstract
Abstract
There is a general notion that the COVID pandemic has made access to adequate health care difficult. A retrospective study looked at patients with acute myocardial infarction (AMI) admitted to a hospital, including the time between admission and diagnosis, the time until treatment, and the delay in transferring to a hospital with a catheterization laboratory in the case of ST-Elevation Myocardial Infarction (STEMI).The period analysed was March to July 2019 and March to July 2020 (first Covid pandemic wave). 197 patients, 101 in 2019 (SCA19) and 96 in 2020 (SCAcov), 142 males (72%) mean age 67.3±12.6. It was observed in 2019 29 STEMI and 72 acute myocardial infarct without ST elevation (NSTEMI) na 2020 36 STEMI and 60 NSTEMI, this proportions didn't achieve statistical meaning χ2(1)=1.719, p=0.226. When compared SCA19 versus SCAcov there were no differences between groups in relation to demographic data. The clinical presentation (none, hemodynamic instability, refractory pain, arrhythmia, mechanic complication, acute heart failure) not varied between groups χ2(6)=3.42, p=0.755. When analysed, between SCA19 and SCAcov, there were no significant time difference between the admission and the electrocardiogram execution (MSCA19 = 44.78; MSCAcov = 56.84; Tweich (132.66) = −0.73, p=0.476 g Hedge = 0.71, between time of admission and time of diagnosis MSCA19 = 264.84; MSCAcov = 254.2; Tweich (188.81) = −0.34, p=0.731 g Hedge = 0.05, and the duration of hospitalization MSCA19 = 5.90; MSCAcov = 5.78 U=9400, Z=−0.263, p<0.792.
Conclusion
In COVID times even with the all restrictions and contingencies lived in hospitals our results pointed to no significant changes in the variables analysed. Interestingly, in spite of no significant difference, a slightly more delay in ECG execution, higher prevalence of STEMI but a short time of diagnosis were observed.

Introduction
Resistant hypertension is a major health problem due to the increased risk of cardiovascular events and mortality. Physical activity and exercise reduces blood pressure in resistant hypertension and is associated with lower cardiovascular risk and mortality. It is presently recommended that physical activity assessment should be a priority in all visits to health settings
Purpose
This study aims to determine if the Brief Physical Activity Assessment Tool (BPAAT), a 2-question tool to assess physical activity, is a valid instrument to detect inactive patients with resistant hypertension.
Methods
Sixty patients with a diagnosis of resistant hypertension were recruited. Outcome measures included clinical data, blood pressure and daily physical activity. Physical activity was objectively measured over a 7-day period with an accelerometer and subjectively assessed (self-assessment) by the BPAAT. The association between the BPAAT and accelerometry, according to the BPAAT scoring categories, was assessed bythe percentage of agreement, Cohen’s Kappa and sensitivity and specificity.
Results
Patients (33 were male) had a mean age of 59.4 ± 9.1years, were on average overweight (BMI 29.5 ± 4.5 kg/m2) and on an average of 4.5 ± 0.7 antihypertensive medications. Forty-two patients (70%) were classified as insufficiently active by the BPAAT compared to the 38 (63.3%) insufficiently active patients identified by the accelerometry data. Regarding the questionnaire’s specificity and sensitivity, the BPAAT correctly identified 32 [84.2 (73.1 – 95.3) %] of the 38 ‘insufficiently active’ patients and 12 [54.5 (34.3 – 74.7) %] of the 22 ‘sufficiently active’ patients identified by accelerometry. The agreement between BPAAT and accelerometry to identify sufficiently/insufficiently active patients, according to the BPAAT’s cut-off values was fair to moderate (Kappa = 0.403 (0.162 – 0.674), with a percentage of agreement of 73.3%.
Conclusion
The BPAAT, a 2-question tool to assess physical activity, seems to be a valid and fast solution to identify insufficiently active adults with resistant hypertension during routine clinical visits.

Background
Physical activity has been associated with reduced arterial stiffness in patients with hypertension. However, in resistant hypertension, a specific population with an increased risk for target organ damage, cardiovascular morbidity, and mortality, the evidence is sparse.
Purpose
The present study aimed to determine the association between daily physical activity and arterial stiffness in patients with resistant hypertension.
Methods
Fifty-seven patients with resistant hypertension were recruited. Physical activity was objectively assessed during 7 consecutive days with accelerometers. Arterial stiffness was evaluated using carotid-femoral pulse wave velocity (cf-PWV) .
Results
Participants (50.9% men), aged 58.8 ± 9.4 years, were mainly overweight and were taking in average 4.5 antihypertensive medications. The cf-PWV showed an inverse correlation with light-intensity physical activity (r = -0.290, p = 0.029) and total daily physical activity (r = -0.287, p = 0.030). Additionally, cf-PWV tended to be inversely associated with the number of steps per day (r = -0.242, p = 0.069). Patients with higher risk of cardiovascular events (cf-PWV ≥ 10 m/s) tended to spend less time in light-intensity physical activity (324.0 ± 129.4 vs. 380.5 ± 103.1 min/day, p = 0.090) and to perform less total daily physical activity (351.5 ± 141.7 vs. 411.7 ± 109.1 min/day, p = 0.091) than participants with cf-PWV below the risk threshold value.
Conclusions
Higher levels of total physical activity and daily levels of light-intensity were associated to lower arterial stiffness. These results emphasize the importance of physical activity as a nonpharmacological tool for patients with resistant hypertension.

Abstract
Background:Sick leave (SL) represents an often poorly studied adverse work outcome especially in early axSpA, with speculation around the potential role of clinical and socioeconomic (SE) factors.Objectives:To investigate the occurrence of SL and the impact of clinical and SE factors on SL in early axSpA.Methods:Patients with a clinical diagnosis of axSpA from the DESIR cohort up to 5 years of follow-up (6-month visits in the first 2 years, followed by annual visits) were studied. Time to SL and potential baseline and time-varying predictors were explored, with a focus on SE variables: age, gender, smoking status since last visit, ethnicity (Caucasian vs other), job type based on ‘collar’ (blue vs white), educational status (low vs high -university), marital status (married vs not) and parental status (number of children); and clinical factors including disease activity (ASDAS/BASDAI), function (BASFI), mobility (BASMI), at each time point. The incidence of SL was calculated as the number of SL events over the total number of person-days under observation. Univariable analyses, followed by collinearity and interaction tests, guided subsequent multivariable Cox survival model building.Results:In total, 704 axSpA patients with work-related data were included in this study: mean (SD) age 33.8 (8.6); 46% male. At baseline, 80% of patients were employed; of these, 5.7% reported being on SL, with people shifting in and out of different work states over time. The distribution of first and recurrent SL episodes over time is shown in the figure 1. The incidence of SL amongst those at risk (n=620, 88%) and across the five years of DESIR was 0.05 (95% CI 0.03, 0.06) per 1000 days calculated in a total of 913,559 observed person-days. In survival analyses, 7% (n=43) of those at risk developed SL at some point. Mean (SD) time to SL was 806 (595) days (min 175, max 2021 days). In people who developed SL, 25% did so at 364 days; 50% and 75% at 545 and 1172 days, respectively. Significant differences were seen between baseline socio-demographic, clinical variables and treatment in patients who developed SL at any point, compared to those who did not. In multivariable models (Table 1) older age, higher disease activity, smoking and use of TNFi, the latter likely a proxy to worse disease, were all significantly associated with more SL. Male gender and higher education were associated with less SL. There were no relevant interactions between SE factors and clinical variables.Table 1.Univariable and multivariable model analyses with Sick Leave as outcome.Type of analysisUnivariable analysisMultivariable modelHR (95% CI)HR (95% CI) (N = 614)Explanatory variablesAge1.04 (1.01, 1.08)1.05 (1.01, 1.09)Male gender0.37 (0.19, 0.74)0.41 (0.20, 0.86)High education0.33 (0.17, 0.61)0.48 (0.24, 0.95)Marital status2.44 (1.12, 5.27)NSASDAS (CRP)1.83 (1.34, 2.50)1.49 (1.04, 2.13)BASFI, 0-101.24 (1.09, 1.40)*BASMI, 0-101.76 (1.31, 2.38)*Comorbidity count1.77 (1.22, 2.57)NSHLA-B27 positive0.51 (0.28, 0.93)NSSmoking (current vs not)2.40 (1.31, 4.37)2.55 (1.32, 4.91)NSAID score last week, 0-4001.01 (1.00, 1.01)NSOral Corticosteroid use (vs no)3.90 (1.80, 8.46)NSTNF use2.86 (1.55, 5.28)2.41 (1.27, 4.58)*Variables tested in models separate from ASDAS.

Abstract
Introduction
Music has been said to be emotion’s language. Research confirms a link between music structure and triggered emotions. Objectives To assess the relationship between selected music excerpts and the emotions trigged, in order that the former will be used in future research. Methods An anonymous study was performed in April 2019 on 65 subjects of both sexes, aged 19-
33 (mean=21,09; SD=3,05).Subjects listened 4 excerpts of music, believed to be related either to excitement or to calmness, and answered to a questionary on emotion’s triggered by each exposure. Results Regarding to the music excerpts that were believed to induce excitement 80% of the subjects mentioned exciting emotions, 78% enjoyed the music while 78% didn’t knew them. For the ones that were believed to induce calmness 69% of the subjects mentioned calm emotions, 84% enjoyed the music and 62% didn’t knew the music. In an excerpt of music related to calmness, we observed association between knowing the music and the emotion trigged (p=0,027). The triggered emotion responses were independent of liking the music (P>0,05). Conclusions In our study, independent of liking the music, the participants reported to have perceived the expected emotions triggered by musical excerpts, showing this to be a phenomenon related to music structure. Calmness perception may be also influenced by previous knowledge of the music and related experiences. The role of individual perceptions will be looked for in following studies. Disclosure No significant relationships.

Abstract
This paper presents techniques for evaluating the radiated power in JET disruptions. Disrupting plasmas are shown to have non-axisymmetric radiation profiles, motivating the re-evaluation of the standard techniques for calculating the total radiated power at JET using bolometry. Four single-channel bolometers at different toroidal locations are exploited to quantify the radiation asymmetry. Toroidal radiation peaking factors integrated over the entire disruption of up to 1.5 have been observed when varying the quantity of neon in pellets used in disruptions mitigated by shattered pellet injection. Using synthetic bolometer diagnostics developed with the Cherab spectroscopy modeling framework, we can estimate the systematic error on total power calculations for relevant radiation profiles and improve estimates of the total radiated power. We show that the component of the systematic error on the total power due to the poloidal radiation profile can be reduced from 70% to 10% with suitable assumptions about the structure of the poloidal profile.

Abstract
RESUMO Xenarthras (Mammalia, Dasypodidae) das espécies Dasypus novemcinctus e Euphractus sexcinctus tiveram sua anatomia científica estudada em relação à topografia dos intestinos delgado e grosso, suas relações peritoniais, morfologia externa e irrigação. Medidas dos diferentes segmentos intestinais e do número de vasos a eles destinados foram tomadas para fins comparativos. O método previu: fixação (formol 7%); injeção de látex; dissecação e fotodocumentação. Espacialmente, embora os intestinos sejam fixados por dupla membrana peritoneal, como em outros vertebrados, nestes a serosa conectou o duodeno, o jejuno, o íleo e os cólons em um único ligamento fixado no dorso do animal. Duodeno e pâncreas, intraperitoniais, como o reto, fixaram-se nas pelves maior e menor, respectivamente e dorsalmente. Vasos derivados do tronco celíaco mesentérico e da aorta percorreram o interior do mesoduodeno, do mesentério comum, do mesocólon e do mesorreto, estando estes, ao longo de seus trajetos, relacionados às cadeias linfonodulares intestinais. O modelo de rotação peritoneal, a morfologia externa, bem como o modelo de vascularização intestinal, foram interpretados como basais, diferindo dos vertebrados recentes, conforme o suporte literário.

Abstract
PURPOSE This study aims to report a case of urgent fertility preservation in an oncological patient with collection of immature oocytes in the absence of ovarian stimulation that, through in vitro maturation (IVM), followed by ICSI and cryopreservation of zygotes resulted, 10 years later, in the live birth of a healthy baby. METHODS In September 2008, our clinic performed IVM in a 32-year-old woman diagnosed with a ductal invasive carcinoma with positive estradiol receptors, negative progesterone receptors and positive human epidermal growth factor receptor 2. The retrieval of immature oocytes was performed in the absence of ovarian stimulation after a simple mastectomy and prior to any chemotherapy treatment. The compact cumulus-oocyte complexes (COCs) collected were placed in Lag medium for 2 h, followed by incubation in IVM medium, supplemented with heat inactivated patient serum, recombinant FSH, and recombinant LH. After 30 h in culture, cumulus cells were removed, the metaphase II oocytes were microinjected, and the zygotes obtained were cryopreserved. In 2017, the zygotes were thawed and cultured until day 3. One embryo was transferred and the other cryopreserved. RESULTS Four compact COCs were collected and subjected to IVM. Two oocytes reached metaphase II and were microinjected. Two zygotes were obtained and were cryopreserved at the two pronuclear stage. Approximately 9 years later, the two zygotes were thawed and cultured until day 3. An embryo with 10 cells was transferred and implanted, resulting in the birth of a healthy baby. CONCLUSIONS In cases where urgency to start adjuvant therapy requires immediate oocyte collection, IVM may be the only option to obtain fully competent mature oocytes allowing for effective preservation of the reproductive potential.

Abstract
Introduction
The expected delay of transport between patient location and percutaneous coronary intervention (PCI) centre is paramount for choosing the adequate reperfusion therapy in ST-segment elevation myocardial infarction (STEMI). The central region of Portugal has heterogeneity in PCI assess due to geographical reasons. However, this data is usually presented numerically without providing a visual distribution of patients.
Purpose
We aimed to analyse the impact of distance to PCI centres on mortality in patients with STEMI through visual maps of patients' flow by using an experimental process mining tool, integrated in EIT Health's project PATHWAYS.
Methods
Using the Portuguese Registry of Acute Coronary Syndromes (ProACS), we retrospectively assessed patients with an established diagnosis of STEMI, geographical presentation specified, reperfusion option identified (PCI, fibrinolysis or no reperfusion), short-term outcomes defined as discharge or in-hospital death. With the 2 317 patients that fulfilled the criteria, we used a process mining tool to build national and regional models that represent the flow of patients in a healthcare system, enhancing differences between groups.
Results
Colour gradient in nodes and arrows changes from green to red, with green representing a lower number of patients as opposed to red. In the national model, most patients from all regions had PCI. Mortality was similar between PCI and fibrinolysis groups (4%) but higher in those without reperfusion (9%). In the central region model, one third of the patients were more than 120 minutes away from a PCI centre. Despite that, almost one third of these patients had PCI instead of fibrinolysis. In this model, fibrinolytic therapy had higher in-hospital survival rate than PCI (98% vs. 94%). Overall mortality was higher in the central model compared with the national model (6.92% vs. 5%). Central region had less PCI (53% vs. 73%), more fibrinolysis (15% vs. 7%) and more patients with no reperfusion (32% vs. 20%).
Conclusion
In the ProACS registry, mortality was higher in the central region compared with national data. Even though global interpretation of these findings is limited by underrepresentation from certain central areas, process mining offers an easily understandable view of patients flow. With its statistical upgrade and continuous development, this tool will facilitate the analysis of big data and comparison between groups.

Interactions between lipid source and vitamin A on broiler performance, blood parameters, fat and protein deposition rate, and bone development. Poult Sci 2020; 100:174-185. [PMID: 33357679 PMCID: PMC7772659 DOI: 10.1016/j.psj.2020.09.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 08/02/2020] [Accepted: 09/01/2020] [Indexed: 12/22/2022] Open
Abstract
A total of 2622 male broilers were distributed in a 2 × 5 factorial design, using 2 lipid sources (soybean oil and palm fat), 5 levels of vitamin A supplementation (0, 3,000, 6,000, 12,000, and 24,000 IU kg−1), with 10 replicates, and also 1 control diet (CD) for each lipid source used (7 replicates), each experimental unit being composed of 23 birds. During the first 21 d (how were the birds fed) and from 22 to 42 d of age, a redistribution of the treatments was carried out in a 2 × 2 × 5 factorial design: half of the repetitions of each treatment received the diet of the initial treatment, and the others received the CD with its type of lipid source. In the phase from 1 to 21 d of age, the effect of lipid source on feed intake (FI) and feed conversion ratio (FCR), and the effect of vitamin supplementation on FI and weight gain (WG) were observed, with a quadratic response for both variables. At 42 d of age, the lipid source and vitamin A level influenced the FI, whereas the WG and FCR showed interactions between period and the level of vitamin A supplementation. Neither lipid source resulted in blood parameters out of the typical pattern for birds, and the same was observed in relation to dietary vitamin A supplementation. From 1 to 21 d of age, a vitamin A supplementation of 15,585 IU kg−1 was estimated, and at 42 d, 15,527 IU kg−1 and 15,148 IU kg −1 were estimated for the periods 1 to 21 d and 1 to 42 d, respectively.

Abstract
Background SARS-CoV-2 infection has caused a global pandemic. Many of the medications identified to treat COVID-19 could be connected with QTc prolongation and its consequences. Methods Non-ICU hospitalized patients of the three centres involved in the study from the 19th of March to the 1st of May were included in this retrospective multicentre study. Relevant clinical data were digitally collected. The primary outcome was the incidence of QTc prolongation ≥ 500 ms, the main secondary outcomes were the Tisdale score ability to predict QTc prolongation and the incidence of ventricular arrhythmias and sudden deaths. Results 196 patients were analysed. 20 patients (10.2%) reached a QTc ≥ 500 ms. Patients with QTc ≥ 500 ms were significantly older (66.7 ± 14.65 vs 76.6 ± 8.77 years p: 0.004), with higher Tisdale score (low 56 (31.8%) vs 0; intermediate 95 (54.0%) vs 14 (70.0%); high 25 (14.2%) vs 6 (30.0%); p: 0.007) and with higher prognostic lab values (d-dimer 1819 ± 2815 vs 11486 ± 38554 ng/ml p: 0.010; BNP 212.5 ± 288.4 vs 951.3 ± 816.7 pg/ml p < 0.001; procalcitonin 0.27 ± 0.74 vs 1.33 ± 4.04 ng/ml p: 0.003). After a multivariate analysis the Tisdale score was able to predict a QTc prolongation ≥ 500 ms (OR 1,358 95% CI 1,076–1,714p: 0,010). 27 patients died because of COVID-19 (13.7%), none experienced ventricular arrhythmias, and 2 (1.02%) patients with concomitant cardiovascular condition died of sudden death. Conclusions In our population, a QTc prolongation ≥ 500 ms was observed in a minority of patients, no suspected fatal arrhythmias have been observed. Tisdale score can help in predicting QTc prolongation.

Abstract
Abstract
Background
12 lead-Holter monitoring is commonly used for the assessment of type 1 Brugada repolarization"s burden. However, data considering the prevalence and morphology of premature ventricular contractions (PVC) in these patients is lacking.
Purpose. We investigated the prevalence of PVCs in subjects with Brugada syndrome (BRs) phenotype during 24-hour 12 lead-Holter monitoring (12-L Holter), trying to identify their origin according to morphology.
Methods. From January 2013 to September 2018, a total of 156 patients with type 1 BRs phenotype (spontaneous or drug induced) were screened for PVCs. In these patients we placed the right precordial leads at the second (V1-V2) and the forth (V3-V4) intercostal spaces.
Results. 83 subjects (53%) displayed PVCs. Their mean age was 50 years (range 21-73) and 63 (76%) were male. 14 subjects (17%) had a spontaneous type 1 repolarization whereas 69 (83%) presented a drug induced type 1. One patient had implanted an ICD as secondary prevention after an aborted sudden cardiac death. The others were mostly asymptomatic as only five of them (6%) had history of suspected cardiac syncope. 17 subjects (20%) had performed an electrophysiological study, which resulted positive in 3 cases (4%). The population without PVCs had similar baseline characteristics.
In 59 (71%) patients PVCs were monomorphic, in the other 29% we analyzed the prevalent morphology.
PVCs were classified according to their morphology as follows
(i) left bundle branch block (LBBB)/inferior axis suggesting an origin from the right ventricular outflow tract (RVOT), that was shown in 40 (48%) subjects; (ii) right bundle branch block (RBBB)/left axis suggesting an origin close to the posterior fascicle of the left bundle branch in 36 (43%). The other 7 patients presented several morphologies.
According to their number during the 24-hour monitoring, PVCs were arbitrarily classified as follows: (i) 1-59,present in 62 patients (75%); (ii) 60-749, present in 16 patients (19%); (iii) 750-9000, present in 4 patients (5%); (iv) >9000, in only one patient (1%).
Conclusions. In our population of subjects with BRs phenotype the prevalence of PCVs is similar to that of the general population. Their morphologies suggest an origin from the RVOT or close to the posterior fascicle of the left bundle branch.

Abstract
Background:Clinical studies often omit outcomes that allow the direct estimation of Quality Adjusted Life Years (QALYs) for use in cost effectiveness analyses crucial for informing policy decisions. This means analysts often have to estimate the relationship, “map”, between included outcomes and preference based ones like the EuroQoL EQ5D. In ankylosing spondylitis (AS), the relationship between BASDAI/BASFI and EQ5D has been established but the emergence and growing use of the Ankylosing Spondylitis Disease Activity Score (ASDAS), a new composite index used to assess clinical disease activity, means new mapping tools are required. Furthermore mapping has never been done for the entire axial spondyloarthritis (axSpA) spectrum of patients i.e. including not only patients with AS but also those with non-radiographic axSpA.Objectives:To estimate a robust mapping between ASDAS and EQ5D (3 level version) and to test its performance out of sample (external validation) in patients with axSpA.Methods:Data from an electronic, prospective, nationwide Rheumatic Disease Portuguese Register (Reuma.pt) provided data pertaining to 1140 patients (5483 observations) with a confirmed diagnosis of axSpA was used to develop a model to predict EQ5D from the ASDAS score. We compared a range of different statistical models developed to deal with the complex distributional features of health utility data. A range of criteria examining model fit across the spectrum of disease severity were used to select preferred models. A smaller dataset for out of sample validation from the SPondyloArthritis Caught Early (SPACE) cohort was used, providing data from 317 patients (1225 observations) at five European centres.Results:Characteristics of patients from the Reuma.pt and SPACE are presented in the table. There is a non-linear relationship between ASDAS and EQ5D. We found that a four component mixture model based on a bespoke distribution, with one component constrained to reflect the mass of observations at full health, was the best fitting of the ASDAS models estimated (figure). ASDAS squared and age squared featured as within component variables. The model demonstrated close fit to the observed data where ASDAS was less than 4 but diverged from the mean of the data where ASDAS was higher. There is a very limited data at this more severe level of disease activity. In the out of sample testing, the model continued to perform well overall and exhibited the same divergence from the observed data only where data was sparse.Conclusion:There is a clear relationship between ASDAS and EQ5D that we were able to model reliably using bespoke mixture model based methods. There is more uncertainty regarding model fit at very high levels of disease activity owing to the relative paucity of data from patients in such disease activity state. Future analyses may wish to focus on these severely affected patients in order to improve the robustness of model estimates.Table.Characteristics of patients from the Reuma.pt and SPACE datasetsREUMA (n = 1140)SPACE (n = 317)NMeansdminmaxNmeansdminmaxAge at visit (yrs)548346.5811.9917.7082.70122531.447.7816.1450.46Number of visits54834.815.261.0039.0012254.051.601.008.00ASDAS total score48862.020.970.606.3011812.100.960.645.44BASDAI total score53832.972.260.0010.0012113.272.200.009.80BASFI total score52582.842.410.009.8812051.922.090.009.30EQ-5D-3L54830.700.26-0.591.0012250.690.25-0.591.00Proportion Male54830.5612250.50Figure.

OP0076 CLINICAL DISEASE ACTIVITY, MRI SPINAL INFLAMMATION AND ENTHESITIS ARE KEY DETERMINANTS OF IMPAIRMENT OF SPINAL MOBILITY IN EARLY AXIAL SPONDYLOARTHRITIS – DATA FROM THE DESIR COHORT.

Abstract
Background:It has been shown that spinal mobility impairment in axial spondyloarthritis (axSpA) is independently determined both by irreversible spinal damage and by reversible spinal inflammation. However, these relationships have only been investigated in patients with longstanding disease (ankylosing spondylitis). Moreover, only the composite score Bath Ankylosing Spondylitis Metrology Index (BASMI) has been evaluated rather than individual mobility assessments.Objectives:Our aim was to investigate the determinants of spinal mobility in patients with early axSpA.Methods:We analysed longitudinal data from the DEvenir des Spondyloarthrites Indifférenciées Récentes (DESIR) cohort, collected during the first five years of follow-up. We selected patients with a definite diagnosis of axSpA according to the treating rheumatologist, at the end of follow-up (month 60). Associations were tested using generalised estimating equations (GEE), a multilevel approach that adjusts for within-patient correlation. The Bath Ankylosing Spondylitis Metrology Index (BASMI) or the individual components of BASMI (lateral spinal flexion, tragus-to-wall distance, cervical rotation, anterior lumbar flexion, maximal intermalleolar distance) were used as dependent variables, and clinical and demographic variables were used as independent variables in univariable models. Spinal MRI inflammation was assessed using the Berlin scoring system and radiographic structural damage was assessed using the modified Stoke ankylosing spondylitis spinal score (mSASSS)]. As physical function and quality of life are considered to be hierarchically superior to spinal mobility, they were not included in the analysis. Multivariable models were built, adjusting for potential confounding. Variables with a p-value <0.10 were re-tested in the multivariable models. Six models were built, one regarding the BASMI total score and five regarding the individual components of BASMI.Results:Data from 644 patients and 5152 visits were analysed. In the multivariable analyses (table), we found an independent association between higher BASMI values and age [adjusted B (aB)=1.02, confidence interval (CI)=1.01-1.03], Ankylosing Spondylitis Disease Activity Score-C Reactive Protein (ASDAS-CRP) (aB=1.23, CI=1.15-1.32), enthesitis score (aB=1.02, CI=1.01-1.04) and MRI inflammation score (aB=1.13, CI=1.05-1.23). All individual BASMI components were independently associated with ASDAS-CRP. Apart from maximal intermalleolar distance, all other mobility measures were associated with MRI spinal inflammation. Lateral spinal flexion, cervical rotation and maximal intermalleolar distance were associated with the enthesitis score. mSASSS was associated with lateral spinal flexion and a contributory factor to tragus-to-wall distance and cervical rotation.Conclusion:In early axSpA, spinal mobility impairment is independently determined by clinical disease activity, MRI spinal inflammation and the severity of enthesitis. Maximal intermalleolar distance (which is not a true measure of spinal mobility) was the only measure not associated with MRI spinal inflammation. The influence of spinal inflammation prevails in the early phase of axSpA while spinal damage becomes more relevant in later disease stages.References:None.Disclosure of Interests:Pedro Carvalho: None declared, Ana Marreiros: None declared, Joao Eurico Fonseca: None declared, Adeline Ruyssen-Witrand Grant/research support from: Abbvie, Pfizer, Consultant of: Abbvie, BMS, Lilly, Mylan, Novartis, Pfizer, Sandoz, Sanofi-Genzyme, Pedro M Machado Consultant of: PMM: Abbvie, Celgene, Janssen, Lilly, MSD, Novartis, Pfizer, Roche and UCB, Speakers bureau: PMM: Abbvie, BMS, Lilly, MSD, Novartis, Pfizer, Roche and UCB

Abstract
Background:The Glucocorticoid Low-dose Outcome in Rheumatoid Arthritis Study (GLORIA) is an international investigator-initiated pragmatic randomized trial designed to study the effects of low-dose glucocorticoids (GCs) in elderly patients with Rheumatoid Arthritis (RA).The research team is also committed to promote a better understanding of the risks and benefits of these drugs among health professionals and patients. In order to achieve these goals, it is important to assess the current ideas and concerns of patients regarding GCs.Objectives:To evaluate the current patient perspective on the efficacy and risks of GCs in RA patients who are or have been treated with GCs.Methods:Patients with RA completed an online survey (with 5 closed questions regarding efficacy and safety) presented in their native language. RA patients were recruited through a variety of patient organizations representing three continents. Patients were invited to participate through national patient organizations. In the USA, patients were also invited to participate through MediGuard.org. Participants were asked for their level of agreement on a 5-point Likert scale.Results:1344 RA patients with exposure to GCs, from Brazil, USA, UK, Portugal, Netherlands, Germany and 24 other countries** participated: 89% female, mean age (SD) 52 (14) years and mean disease duration 13 (11) years. The majority of participants (84%) had ≥10 years of education. The duration of GCs exposure was 1.6 (4.2) years. The majority of participants had read articles or pamphlets on the benefits or harms of GC therapy.Regarding GCs efficacy (table 1), high levels of endorsement were found: about 2/3 of patients considered that GCs as very useful in their case, more than half considered that GCs were effective even at low doses, and agreed that GC improved RA symptoms within days.Regarding safety (table 1), 1/3 of the participants reported having suffered some form of serious adverse events (AEs) due to GCs, and 9% perceived this as “life-threatening. Adverse events had a serious impact on quality of life, according to about 1/3 of the respondents.Conclusion:Patients with RA exposed to GC report a strong conviction that GCs are very useful and effective for the treatment of their RA, even at low doses. This is accompanied by an important prevalence of serious AEs. Understanding the patient perspective can improve shared decision-making between patient and rheumatologist.References:Funding statement:This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 634886.Disclosure of Interests:Tânia Santiago: None declared, Marieke Voshaar Grant/research support from: part of phd research, Speakers bureau: conducting a workshop (Pfizer), Maarten de Wit Grant/research support from: Dr. de Wit reports personal fees from Ely Lilly, 2019, personal fees from Celgene, 2019, personal fees from Pfizer, 2019, personal fees from Janssen-Cilag, 2017, outside the submitted work., Consultant of: Dr. de Wit reports personal fees from Ely Lilly, 2019, personal fees from Celgene, 2019, personal fees from Pfizer, 2019, personal fees from Janssen-Cilag, 2017, outside the submitted work., Speakers bureau: Dr. de Wit reports personal fees from Ely Lilly, 2019, personal fees from Celgene, 2019, personal fees from Pfizer, 2019, personal fees from Janssen-Cilag, 2017, outside the submitted work., Pedro Carvalho: None declared, Frank Buttgereit Grant/research support from: Amgen, BMS, Celgene, Generic Assays, GSK, Hexal, Horizon, Lilly, medac, Mundipharma, Novartis, Pfizer, Roche, and Sanofi., Maurizio Cutolo Grant/research support from: Bristol-Myers Squibb, Actelion, Celgene, Consultant of: Bristol-Myers Squibb, Speakers bureau: Sigma-Alpha, Maarten Boers: None declared, José Antonio P. da Silva Grant/research support from: Pfizer, Abbvie, Consultant of: Pfizer, AbbVie, Roche, Lilly, Novartis

Abstract
During the necropsies of Iberian hares obtained in 2018/2019, along with signs of the nodular form of myxomatosis, other unexpected external lesions were also observed. Histopathology revealed nuclear inclusion bodies in stromal cells suggesting the additional presence of a nuclear replicating virus. Transmission electron microscopy further demonstrated the presence of herpesvirus particles in the tissues of affected hares. We confirmed the presence of herpesvirus in 13 MYXV-positive hares by PCR and sequencing analysis. Herpesvirus-DNA was also detected in seven healthy hares, suggesting its asymptomatic circulation. Phylogenetic analysis based on concatenated partial sequences of DNA polymerase gene and glycoprotein B gene enabled greater resolution than analysing the sequences individually. The hare’ virus was classified close to herpesviruses from rodents within the Rhadinovirus genus of the gammaherpesvirus subfamily. We propose to name this new virus Leporid gammaherpesvirus 5 (LeHV-5), according to the International Committee on Taxonomy of Viruses standards. The impact of herpesvirus infection on the reproduction and mortality of the Iberian hare is yet unknown but may aggravate the decline of wild populations caused by the recently emerged natural recombinant myxoma virus.

Abstract
IntroductionMixed features refers to the presence of high and low symptoms occurring at the same time, or as part of a single episode, in people experiencing an episode of mania or depression. In most forms of bipolar disorder, moods alternate between elevated and depressed over time. A person with mixed features experiences symptoms of both mood “poles” – mania and depression – simultaneously or in rapid sequence.Aims and objectivesTo review the nosological status of bipolar mixed states and its treatment.MethodsOnline search/review of the literature has been carried out, using Medline/Pubmed, concerning “mixed states”, “affective disorder”, “bipolar disorder”.ResultsThe presence of depressive symptomatology during acute mania has been termed mixed mania, dysphoric mania, depressive mania or mixed bipolar disorder. Highly prevalent, mixed mania occurs in at least 30% of bipolar patients. Correct diagnosis is a major challenge. The presence of mixed features is associated with a worse clinical course and higher rates of comorbidities. There is ongoing debate about the role of antidepressants in the evolution of such states.ConclusionsClinical vigilance and careful evaluation are required to ensure mixed states are not missed in the clinical context. Atypical antipsychotics are emerging as the medications of choice in the pharmacological management of mixed states.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
This paper provides a study using Electroencephalography (EEG) to investigate the brain activity during code comprehension tasks. Three different code complexity levels according to five complexity metrics were considered. The use of EEG for this purpose is relevant, since the existing studies were mostly focused on neuroimaging techniques. Using Leave-One-Subject-Out cross-validation procedure for 30 subjects, it was found that the features related with the Gamma activity were the most common in all the folds. Regarding the brain regions, right parietal was the most frequent region contributing with more features. A Linear Discriminant Analysis Classifier for task classification, obtained a F-Measure of 92.71% for Code complexity easy, 52.25% for Code complexity intermediate and 53.13% for Code complexity advanced, revealing an evidence of mental effort saturation with the code complexity degree. This suggests that current code complexity metrics do not capture cognitive load and might not be the best approach to assess bug risk.

Abstract
Cardiac function deterioration of heart failure patients is frequently manifested by the occurrence of decompensation events. One relevant step to adequately prevent cardiovascular status degradation is to predict decompensation episodes in order to allow preventive medical interventions.In this paper we introduce a methodology with the goal of finding onsets of worsening progressions from multiple physiological parameters which may have predictive value in decompensation events. The best performance was obtained for the model composed by only two features using a telemonitoring dataset (myHeart) with 41 patients. Results were achieved by applying leave-one-subject-out validation and correspond to a geometric mean of 83.67%. The obtained performance suggests that the methodology has the potential to be used in decision support solutions and assist in the prevention of this public health burden.

A comprehensive study of the uncertainties in bolometric tomography on JET using the maximum likelihood method. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2019; 90:123502.

Abstract
Essential physical quantities of magnetically confined plasmas are derived on a routine basis from bolometric reconstructions. In the last few years at the Joint European Torus (JET), the Maximum Likelihood method has demonstrated the capability of providing reliable reconstructions for this class of ill-posed problems. The article is focused on quantifying the effects of important sources of errors, usually underestimated, that can influence both the reconstructions and the derived quantities. A complete set of phantoms has been used to test the robustness of the technique. The main sources of uncertainties investigated in this contribution are random noise, presence of outliers in the measurements, uncertainty of the position of the magnetic topology, and missing measurements from damaged or unreliable bolometers. The study provides a comprehensive quantification of the uncertainties to associate with most typical emissivities encountered in practice and constitutes a good basis for a more accurate evaluation of the power balances on the JET.

Abstract
The effectiveness of predictive models in supporting the Clinical Decision is closely related with their clinical interpretability, i.e.the model should provide clear information on how to reach a specific classification/decision. In fact, the development of interpretable and accurate predictive models assumes a key importance as these tools can be very useful in Clinical Decision Support Systems (CDSS). The development of those models may comprise two main perspectives; existent clinical knowledge (clinical expert knowledge, clinical guidelines, current models, etc.) as well as data driven approaches able to extract (new) knowledge from recent clinical datasets. This work focuses in knowledge extraction from recent datasets (data driven) based on computational intelligence techniques. The main hypothesis that supports this work is that individuals with similar characteristics present a similar risk prof ile. Thus, this work addresses the development of stratification models able to learn distinct groups (or classes) of subjects assessing the similarity between characterizing variables. In particular, in the current study a data-driven supervised cluster approach is proposed aiming the derivation of meaningful rules directly from the dataset. The validation was performed based on the largest Portuguese coronary artery disease patient's dataset, provided by the Portuguese Society of Cardiology and comprising 13902 acute coronary syndrome patients. The goal was to assess the risk of death 30 days after admission. The models' performance was assessed through the sensitivity, specificity and geometric mean values. The obtained results show the potential of this approach, as they represent an acceptable performance (GM= 72%) while the clinical interpretability of the model is assured through the derived rules. Despite the achieved results, there are several research directions to be followed in order to enhance this work.
