Abstract
BACKGROUND Amelogenesis imperfecta (AI) and dentinogenesis imperfecta (DI) are two groups of genetically inherited conditions resulting in abnormal enamel and dentin formation, respectively. Children and young people may be adversely affected by these conditions, with significant reduction in oral health related quality of life. Dental management of children with AI and DI is often complex, which is exacerbated by the absence of clear referral pathways and scarce evidence-based guidelines. METHOD The need for increased knowledge and peer support led to the development of a group of UK paediatric dentists with a special clinical interest in the management of children with AI and DI. PURPOSE The aims of this paper are to describe the establishment of an AI/DI Clinical Excellence Network (AI/DI CEN) in paediatric dentistry including outputs and future plans, and to share our collective learning to help support others anywhere in the world advance the care of people with AI or DI.

Abstract
Purpose The European Academy of Paediatric Dentistry (EAPD) has developed this best clinical practice guidance to help clinicians manage deep carious lesions in primary teeth. Methods Three expert groups conducted systematic reviews of the relevant literature. The topics were: (1) conventional techniques (2) Minimal Intervention Dentistry (MID) and (3) materials. Workshops were held during the corresponding EAPD interim seminar in Oslo in April 2021. Several clinical based recommendations and statements were agreed upon, and gaps in our knowledge were identified. Results There is strong evidence that indirect pulp capping and pulpotomy techniques, and 38% Silver Diamine Fluoride are shown to be effective for the management of caries in the primary dentition. Due to the strict criteria, it is not possible to give clear recommendations on which materials are most appropriate for restoring primary teeth with deep carious lesions. Atraumatic Restorative Technique (ART) is not suitable for multi-surface caries, and Pre-formed Metal Crowns (PMCs) using the Hall technique reduce patient discomfort. GIC and RMGIC seem to be more favourable given the lower annual failure rate compared to HVGIC and MRGIC. Glass carbomer cannot be recommended due to inferior marginal adaptation and fractures. Compomers, hybrid composite resins and bulk-fill composite resins demonstrated similar values for annual failure rates. Conclusion The management of deep carious lesions in primary teeth can be challenging and must consider the patient’s compliance, operator skills, materials and costs. There is a clear need to increase the use of MID techniques in managing carious primary teeth as a mainstream rather than a compromise option.

Abstract
Abstract
Introduction
The Shock Index (SI), defined as the ratio of heart rate (HR) to systolic blood pressure (SBP), represents a bedside reflection of the integrated response from the cardiovascular and autonomic systems and has been reported to predict adverse prognosis in patients with acute coronary syndromes (ACS).
Age Shock Index (ASI), the product of SI multiplied with age, could also be useful in this setting, but its prognostic value is yet to be determined in ACS patients.
Methods
Acute myocardial infarction patients included in a national registry between October 2010 and January 2022. Optimal shock index cutoff was determined according to ROC curve analysis. Patients were categorized into two groups based on their initial ASI. Baseline characteristics, management and outcomes were compared between the two groups. The primary outcome was in-hospital cardiovascular death.
Results
A total of 27312 patients were included with a mean age of 66±13 years, 72.3% male, 47.5% with ST-elevation myocardial infarction. Based on ROC analysis, which showed AUC=0.80, the optimal ASI cutoff was 44 (with a sensitivity of 73% and a specificity of 74%); 19997 patients (73.2%) had an ASI <44 and 26.8% had an ASI ≥44. The former group was older (mean age of 75±10.0 vs 63±13.0 years, p<0.001), and had more comorbidities: arterial hypertension (77.3% vs 66.3%, p<0.001), diabetes mellitus (39.8% vs 28.1%, p<0.001), peripheral artery disease (7.1% vs 4.4%, p<0.001) and previous history of heart failure (11.0% vs 4.3%, p<0.001).
Patients with ASI ≥44 had higher Killip class at admission and worse left ventricular ejection fraction on discharge (46.0±13.0 vs 53.0±11.0, p<0.001).
In a multivariate regression analysis, after adjusting for possible confounders, ASI ≥44 was an independent predictor of cardiovascular death (HR 3.09, 95% CI: 2.56–3.71, p<0.001).
ASI was a significantly better predictor of cardiovascular death than Shock Index (AUCASI = 0,80 vs AUCSI = 0.72, p<0,0001), but not in comparison to GRACE score (AUCASI=0.80 vs AUCGRACE=0.85, p<0.001) and TIMI (score AUCASI=0.80 vs AUCGRACE=0.84, p<0.001).
At one year, using a Kaplan Meyer survival analysis, mortality was higher in patients with ASI ≥44 (log rank p<0.001)
Conclusion
ASI can identify almost immediately ACS patients at high risk of cardiovascular death, and combined with its simple use, makes it a practical tool for early risk stratification in these patients.

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
It is known that low diastolic blood pressure (DBP) at admission is associated with short-term cardiovascular events after acute coronary syndrome (ACS). However, there is a lack of further investigation into the nonlinear relationship between admission diastolic blood pressure (DBP) and adverse outcomes of ACS patients.
Objective
To investigate the relationship between admission diastolic blood pressure and subsequent cardiovascular mortality in patients with acute coronary syndrome.
Methods
Retrospective study of patients with ACS periodically included in our center registry between October/2012 and September/2018. Patients with class killip 4 at admission or that needed ionotropic support during hospitalization were excluded. The association between admission DBP and cardiovascular mortality during the follow-up period among this population was analyzed using multivariate COX regression model. Results were presented according to DBP quartiles: Q1, less than 70 mm Hg; Q2, from 71 to 80 mm Hg; Q3, from 81 to 90 mm Hg; Q4, above 90 mmHg.
Results
A total of 548 patients were included in this cohort study. Mean patient age was 65.9±13.1 years and 75.2% were men. A nonlinear relation was observed between DBP at admission and cardiovascular mortality over the follow-up.
During a median follow-up of 42 months (IQR: 27–59), 47 patients (8.6%) died from cardiovascular causes. After adjusting for potential confounders (age and diabetes mellitus), patients in Q3 had the lowest risk for cardiovascular death by Cox proportional hazard model (HR 0.44; 95% CI: 0.16–1.00). Meanwhile, compared with Q1, Q3 patients had significantly lower risk for cardiovascular death (HR 0.35, 95% CI: 0.13–0.92).
Conclusion
Among patients admitted for ACS, there is a U curve relationship between admission DBP and risk for cardiovascular death. These results could be explained by a reduction in diastolic coronary blood flow which influences myocardial oxygen supply relative to the necessary demand in an ACS.

Abstract
PURPOSE Dental bleaching in paediatric patients can be used to address discolouration of teeth due to trauma, endodontic treatment, or enamel and dentine defects. Despite being a minimally invasive and successful treatment, the use of bleaching products in children and young people remains controversial. This evaluation was designed to provide insight into the child's perspective on dental bleaching and the influence that this treatment has upon their life. METHOD A dental bleaching patient reported outcome measure (PROM) was developed and piloted in 2019. Data were collected from 3 UK units (January-March 2020). Children attending these units for bleaching reviews were invited to complete the PROM. RESULTS Twenty seven PROM questionnaires were completed including 19 courses of external bleaching and 8 courses of internal/external bleaching. The average age was 14 years old (9-17 years). The common indications for bleaching were Amelogenesis Imperfecta, dental trauma and Molar Incisor Hypomineralisation. Patients reported improvements in their appearance (89%) and self-confidence (81%). Sensitivity was the most common side effect, reported in 63% of cases. CONCLUSION This PROM supports the use of dental bleaching in children and young people when treating dental disease that causes discolouration. Bleaching not only improved the appearance of teeth, but also patients' self-confidence. Sensitivity is a common side effect and clinicians should discuss this common risk and its management with patients and their families.

Abstract
Introduction : La première promotion d’internes de diplôme d’études spécialisées (DES) de médecine d’urgence est arrivée en novembre 2020 sur un statut inédit de Docteur Junior. De par leur nouveauté, il apparaît intéressant d’évaluer la satisfaction et la formation de cette promotion.
Matériel et méthodes : Une enquête nationale a été réalisée par les membres de la Commission jeunes de la SFMU et diffusée via les réseaux sociaux et les coordonnateurs de DES. Le questionnaire était composé d’une partie sociodémographique, d’une partie sur l’enseignement reçu, une sur les points positifs et négatifs de la maquette et une sur les choix de stage de Docteur Junior. Les variables qualitatives étaient exprimées en pourcentage. Les variables quantitatives étaient exprimées par une moyenne et un écart-type.
Résultats : Sur les 460 étudiants ayant choisi le DESMU en 2017, 142 (31 %) réponses ont été obtenues pour un âge moyen de 28 (± 2) ans, 73 étaient des hommes (51 %), 72 travaillaient en CHU (51 %). Les éléments de choix les plus évoqués sont l’ambiance de l’équipe et la réalisation d’un stage antérieur dans le service. Les étudiants ont bénéficié majoritairement de cours magistraux présentiels et de simulation. Le choix de l’appariement a été respecté pour 86 % des cas. La majorité des étudiants ne souhaite retirer aucun stage de la maquette.
Conclusion : Les internes sont majoritairement satisfaits de leur formation et de l’appariement. Ils choisissent leur lieu de stage de Docteur Junior en fonction de précédents stages dans la structure et d’une bonne ambiance dans l’équipe.

Abstract
Stage IV colorectal cancer treatment includes targeted therapy depending on RAS status. During disease progression, loss or gain of RAS mutations could happen, supporting the hypothesis of the evolutionary pressure of therapy. Circulating tumor DNA (ctDNA) are nucleic acids released to the bloodstream by the tumor during its development and may be detected by liquid biopsy. The Idylla© Biocartis, a fully automated real-time-PCR-based molecular diagnostic system, was used in a patient with metastatic colorectal cancer with a NRAS mutation in progression after several therapeutic lines. The ctDNA mutational analysis was performed and revealed the absence of mutations in the KRAS, NRAS, and BRAF genes. The patient started the third line of palliative chemotherapy with irinotecan + cetuximab and achieved a partial response for the first time. The authors describe a case in which liquid biopsy determined the higher progression-free survival achieved.

Abstract
Abstract
Introduction
TCF21 is expressed in cells that migrate into the developing plaque facilitating the repair of the vessel wall. However, the rs12190287 risk allele (C) of TCF21 can lead to reduced TCF21 expression being a risk factor for CAD.
Purpose
Investigate whether the variant rs12190287 G>C of TCF21 gene represents a risk factor for CAD in a Southern European population.
Methods
Case-control with 3139 individuals, 1723 CAD patients and 1416 controls, adjusted for age and gender. Genotyping of TCF21 rs12190287 G>C was performed by TaqMan Real-Time PCR. CAD association of each genetic model was evaluated.
Multivariate logistic regression analysis adjusted for confound variables: smoking status, dyslipidemia, diabetes, physical inactivity, and hypertension, was made.
Results
TCF21 rs12190287 G>C has shown significant genotypic differences between cases and controls: GG 9.5% vs 11.9%; GC 43.2% vs 46.5% and CC 47.3% vs 41.6%. CAD risk was significant in all models: dominant (OR 1.28; 95% CI: 1.02–1.61; p=0.033); recessive (OR 1.26; 95% CI: 1.09–1.45; p=0.001); additive (OR 1.20; 95% CI: 1.08–1.34; p=0.001). After multivariate analysis, TCF21 variant was independently associated with CAD.
Conclusion
TCF21 variant rs12190287 G>C may be a risk factor for CAD. It is plausible that TCF21 loci exert its protective effect by promoting infiltration of fibromyocytes in the coronary wall lesion and fibrous layer and loss of TCF21 expression can result in fewer fibromyocytes to fibrous cap increasing vulnerability of the plaque.

Abstract
Abstract
Background
Currently, the evaluation of biomarkers HER-2 and ER is critical for targeting therapy for breast cancer and is performed by experienced pathologists, which takes time and causes a certain interobserver variability. The use of histological slide scanners coupled with the application of software for immunoexpression quantification can be profitable in pathological laboratories routine. This study aims to compare the quantification of HER-2 and ER immunoexpression employing automatic algorithms, using as standard the evaluation performed by a pathologist.
Methods
From the archive since 2016 to 2018 were retrieved 75 immunostained slides for HER-2 and 76 immunostained slides for ER with invasive breast carcinoma diagnosis. The slides were scanned in Aperio CS2 and the immunostaining signal was quantified in Aperio Imagescope using a membrane and nuclear algorithm, respectively. The concordance between the scores obtained and the previous assessment was calculated by Cohen’s Kappa coefficient as well as the sensitivity and specificity for each algorithm.
Results
Both algorithms showed an almost perfect concordance with the conventional method (k = 0.94 for HER-2; k = 0.92 for ER). Digital evaluations presented a sensitivity of 100% for both biomarkers, and a specificity of 100% for HER-2 and 80% for ER.
Conclusions
This assay showed that applying signal quantification software for HER-2 and ER in digitized slides is accurate, as these tools have potential to be implemented in laboratory routine. However, it will be necessary to increase the sample to obtain more reliable values and extend this study to the PR and Ki67 biomarkers since both carry prognostic and predictive information as well.

Abstract
The mitochondrial genome of Neurospora crassa has been less studied than its nuclear counterpart, yet it holds great potential for understanding the diversity and evolution of this important fungus. Here we describe a new mitochondrial DNA (mtDNA) complete sequence of a N. crassa wild type strain. The genome with 64 839 bp revealed 21 protein-coding genes and several hypothetical open reading frames with no significant homology to any described gene. Five large repetitive regions were identified across the genome, including partial or complete genes. The largest repeated region holds a partial nd2 section that was also detected in Neurospora intermedia, suggesting a rearrangement that occurred before the N. crassa speciation. Interestingly, N. crassa has a palindrome adjacent to the partial nd2 repeated region possibly related to the genomic rearrangement, which is absent in N. intermedia. Finally, we compared the sequences of the three available N. crassa complete mtDNAs and found low levels of intraspecific variability. Most differences among strains were due to small indels in noncoding regions. The revisiting of the N. crassa mtDNA forms the basis for future studies on mitochondrial genome organization and variability.

Abstract
Introduction People with schizophrenia experience higher levels of stigma compared with other diseases. The analysis of social media content is a tool of great importance to understand the public opinion toward a particular topic. Objectives The aim of this study is to analyse the content of social media on schizophrenia and the most prevalent sentiments towards this disorder. Methods Tweets were retrieved using Twitter’s Application Programming Interface and the keyword “schizophrenia”. Parameters were set to allow the retrieval of recent and popular tweets on the topic and no restrictions were made in terms of geolocation. Analysis of 8 basic emotions (anger, anticipation, disgust, fear, joy, sadness, surprise, and trust) was conducted automatically using a lexicon-based approach and the NRC Word-Emotion Association Lexicon. Results Tweets on schizophrenia were heterogeneous. The most prevalent sentiments on the topic were mainly negative, namely anger, fear, sadness and disgust. Qualitative analyses of the most retweeted posts added insight into the nature of the public dialogue on schizophrenia. Conclusions Analyses of social media content can add value to the research on stigma toward psychiatric disorders. This tool is of growing importance in many fields and further research in mental health can help the development of public health strategies in order to decrease the stigma towards psychiatric disorders.

Abstract
Introduction Valproic Acid (VPA) is one of the most commonly used mood stabilizer drugs. Although uncommon, serious adverse effects have been reported. One particularly relevant side effect is the induced encephalopathy, usually secondary to Hyperammonemia. However, some descriptions have shown an altered mental state with normal serum levels of ammonia. Objectives We aim to present a case of VPA induced-encephalopathy without hyperammonemia and emphasize its suspicion when patients taking VPA present altered mental states. Methods We present a clinical case of VPA induced-encephalopathy without Hyperammonemia and a qualitative review of this topic using the Pubmed database. Results A 66-year-old woman, with an history of Major Depressive Disorder, previously medicated with Venlafaxine 75mg/day and Mirtazapine 30mg/day, was admitted in our acute psychiatric inpatient unit due to a first manic episode. During the stay, her antidepressants were interrupted, and she was started on VPA, then optimized to 750mg/day. After that, she presented an altered mental state with confusion and prostration. Analytical results were normal including normal ammonia levels and no imagiological abnormalities. Despite these results, we decided to stop VPA empirically. The patient clinical status resolved the day after. Conclusions Studies have shown that only a few patients have developed encephalopathy with normal serum levels of ammonia. Although the pathogenesis behind this remains unknown, a few mechanisms have been proposed. Therefore, it is important to remind that even without abnormal analytical status, VPA is a possible cause of encephalopathy. We also emphasize the need for further studies on the mechanisms behind this phenomenon. Disclosure No significant relationships.

Abstract
Introduction
Mood destabilization and induced manic episodes are well-known phenomenon under antidepressant medications. However, even with a cautious introduction of antidepressants, it’s important to be aware of possible pharmacological interactions. Terbinafine is a known inhibitor of CYP2D6, a major hepatic metabolizer of a full list of antidepressant medications, and so capable of raising their serum levels and potentiating their side effects. Objectives With this case report we aim to emphasize the importance of cautious usage of Terbinafine when combined with antidepressant medications. Methods We present a clinical case of an induced first manic episode after the introduction of Terbinafine in a patient under antidepressant medication and a qualitative review on the topic, using PubMed database. Results A 66-year-old woman, with an history of Major Depressive Disorder, previously medicated with Venlafaxine 75mg/day and Mirtazapine 30mg/day, was brought to the emergency department because of psychomotor agitation. She also had an history of seasonal fluctuating mood, although never fulfilling the criteria for Bipolar Disorder. At admission, her clinical status was compatible with a manic episode. This episode followed two months after the initiation of Terbinafine for onychomycosis. Conclusions
There are few studies that have shown antidepressant toxicity mediated by an interaction with Terbinafine. As far as we know this is the first case of induced mania after the introduction of Terbinafine. Therefore, it is important to remind that Terbinafine is a potential interacting agent when combined with psychotropic medications.

Abstract
Background Dense Bone Islands (DBIs) are anatomic variants defined as radiopaque lesions consisting of hamartomatous cortical bone, often presenting as incidental radiographic findings. DBIs can also be known as idiopathic osteosclerosis, bone whorl, focal periapical osteopetrosis, bone scar and enostosis. We found a paucity of literature for management and reporting of this condition in children. For this reason, the authors describe sixteen cases of children and adolescents with dense bony islands and suggest a pathway for management. Case series Cases presented to the RNENT and Eastman Dental Hospital or private practice, either as chance findings or for diagnosis and treatment planning of undiagnosed radiopaque areas. The individuals were aged between 10 and 17 years; 6 boys and 10 girls. All radiographic reports described DBIs. Diagnoses were confirmed by a Dental and Maxillofacial Radiology Consultant and advised no intervention. In some cases, monitoring was advised. Caution in orthodontic tooth movement was advised for five patients. Conclusion DBIs are common findings that seldom require treatment; however, caution should be exercised when undertaking orthodontic movement in the area of a DBI due to a potential risk of root resorption. Accurate identification and multidisciplinary management are of utmost importance.

Abstract
SYNTHESIS, CHARACTERIZATION AND JUDD-OFELT ANALYSIS OF Eu(III) OR Sm(III) β-DIKETONATE COMPLEXES. The lanthanide complexes [Ln(bmdm)3(L)] where Ln(III) = Eu and Sm were synthesized successfully using the diketone (1-(4-methoxyphenyl)-3-(4-tert-butylphenyl) propane-1,3-dione) (bmdm) and (L) = 1,10-phenanthroline (phen), 2,2’-bipyridine (bipy) ligands. The coordination modes were determined as bidentate chelate by the FT-IR. The ground state geometry was determined using the Sparkle/AM1 implemented in MOPAC2016 package. Europium complexes exhibit the characteristic emission bands that arise from 5 D0→7 FJ (J = 0-4); the presence of just one 5 D0→7 F0 line transition means that this site is without the center of inversion.Samarium complexes display transitions at 4 G5/2→6 HJ (J = 5/2; 7/2; 9/2 and 11/2), being the 4 G5/2→6 H9/2 the most intense, indicating that the forced electric dipole mechanism is predominant when compared with the magnetic dipole ones. The intensity parameters Ω2 and Ω4 were calculated according to the emission spectra for Eu(III) and absorption spectra for Sm(III). The high Ω2 values demonstrated that the lanthanide ion in bipy or phen complexes is in a highly polarizable chemical environment. The emission lifetime (τ) increases compared with that of precursor aquo complexes, confirming that the non-radiative quenching is minimized. The low quantum efficiency is a result of NIR emissions and non-radiative transitions of Sm(III).

Abstract
Abstract
Background
Despite being a controversial subject, multiple guidelines mention the use of Coronary Artery Calcification (CAC) scoring in the cardiovascular risk prediction, in asymptomatic population. The inclusion of CAC scoring in traditional risk models may help in decision-make providing better cardiovascular risk stratification.
Purpose
The aim of our study is to estimate the impact of CAC scoring in cardiovascular events risk prediction in a model based on traditional risk factors (TRFs).
Methods and results
The study consisted of 1052 asymptomatic individuals free of known coronary heart disease, enrolled from GENEMACOR study and referred for computed tomography for the CAC scoring assessment. A cohort of 952 was followed for a mean of 5.2±3.2 years for the primary endpoint of all-cause of cardiovascular events. The following traditional risk factors were considered: (1) current cigarette smoking, (2) dyslipidemia, (3) diabetes mellitus, (4) hypertension and (5) family history of coronary heart disease. Among this population, the extent of CAC differs significantly between men and women in the same age group. Therefore, the distribution of CAC score by age and gender was done by using the Hoff's nomogram (a). According to this nomogram, 3 categories were created: low CAC (0≤CAC<100 and P<50); moderate CAC (100≤CAC<400 or P50–75) and high CAC (CAC≥400 or P>75). Two Cox regression models were created, the first only with TRFs and the second adding the CAC severity categories. When including CAC categories to the TRFs, the higher severity level presented a significant risk of MACE occurrence with an HR of 4.39 (95% CI 1.83–10.52; p=0.001).
Conclusion
Our results point to the importance of the inclusion of CAC in both primary and secondary prevention to an improved risk stratification. Larger prospective multicentre cohorts with longer follow-up should reproduce and validate these findings.

Abstract
Abstract
Background
Upgrade to resynchronization therapy (CRT) from conventional pacemaker (P) or defibrillator (D) is common practice in Europe. However, guidelines (GL) are discordant: Pacing GL give a class I recommendation, while Heart Failure (HF) GL provide a class IIb indication. Previous studies suggested worse outcomes in upgraded patients (pts).
Aim
To compare response rate and clinical outcomes in a cohort of pts receiving de novo or upgrade to CRT.
Methods
Single-center retrospective study of consecutive pts submitted to CRT implantation (2007–2017). Major adverse cardiac events (MACE) included HF hospitalization (HHF) or all-cause mortality. Clinical response was defined as New York Heart Association class improvement without MACE in the first year of follow-up (FU). Left ventricle end-systolic volume reduction of >15% denoted echocardiographic (echo) response. Survival analysis with Kaplan-Meier method and Log-rank test was performed. Propensity-score matching (PSM) analysis was made to adjust for possible confounder variables.
Results
230 CRT recipients (70.9% male, mean age 67±11 years, 71.5% non-ischemic cardiomyopathy, 39.6% CRT-P) were included, of whom 46 (20%) underwent an upgrade. Upgraded pts were older (69.8 vs 65.9 years, p=0.015), with higher rates of permanent atrial fibrillation (37.0% vs 12.7%, p=0.001), moderate to severe valve disease (45.7% vs 22.3%, p=0.002), chronic kidney disease (37.0% vs 17.2%, p=0.005) and treatment with mineralocorticoid receptor antagonists (79.1% vs 52.0%, p=0.002). They were more likely to receive CRT-P (65.2% vs 33.2%, p<0.001) and CRT-D were more often implanted for secondary prevention (60.0% vs 17.9%, p=0.001). No differences emerged in procedural complications, clinical (74.4% vs 71.4%, p=0.712) or echo (66.7% vs 69.7%, p=0.822) response rates.
During a median FU of 3±4 years, all-cause mortality was similar among groups (Log Rank test, p=0.522, unadjusted hazard ratio [HR] 1.25, confidence interval [CI] 95% 0.62–2.49, p=0.534). There was a statistical tendency for higher MACE rate in the upgrade group (Log Rank test, p=0.064, HR 1.66, CI 95% 0.95–2,91, p=0.076). No differences were found in lead dislodgement (10.9% vs 7.1%, p=0.368) or endocarditis (2.2% vs 4.3%, p=0.692) rates.
PSM analysis identified 88 matched pairs (46 upgrade/42 de novo pts). In this cohort, all-cause mortality (Log Rank test, p=0.77, HR 0.89, CI 95% 0.39–2.03, p=0.78) and MACE (Log Rank test, p=0.36, HR 1.38, CI 95% 0.68–2.81, p=0.37) were comparable between groups [graph no. 1].
Conclusion
Upgrade to CRT was similar to de novo implantation in terms of complications and clinical and echo response, in this cohort. The risk for MACE and mortality was also comparable.

Abstract
Abstract
Background
TCF21 gene, encodes a basic-helix- loop- helix transcription factor, playing a critical action in the development of epicardial progenitor cells that give rise to coronary artery smooth muscle cells (SMC) and cardiac fibroblasts. Recent data suggest that TCF21 may play a role in the state of differentiation of SMC precursor cells that migrate to vascular lesions and contribute to fibrous cap.
Purpose
Investigate the association of TCF21 rs12190287G>C variant with coronary artery disease (CAD) in a Portuguese population and its role on the prognosis.
Methods
Case-control study with 3120 participants, 1687 coronary patients with at least 75% obstruction of a major coronary artery and 1433 controls. Genotyping used the TaqMan technique (Applied Biosystems) and then a univariate and multivariate logistic regression analysis were performed. After a mean follow-up of 5.01±4.2 years (interquartile range 1.96–7.57), the occurrence of the combined Major Adverse Cardiovascular Events (MACE) (Cardiovascular Mortality, non-fatal Myocardial Infarction, new Revascularization, Cerebrovascular Disease and Peripheric Vascular Disease) were registered and analysed by Cox regression. Finally, Kaplan-Meier survival estimate was performed.
Results
In the total population, GC+CC genotype was found to be associated with CAD with an OR of 1.285; CI: 1.022–1.614; p=0.031. After multivariate logistic regression, adjusted to traditional risk factors, the association with CAD remained significant for this genotype (OR=1.340; CI: 1.042–1.723; p=0.022).After Cox regression adjusted for confounding variables (age and sex, hypertension, diabetes, smoking, dyslipidemia, eGFR, Ejection fraction <55) the mutated genotype remained a significant predictor of MACE (HR=1.420; CI: 1.032–1.953; p=0.031). The individuals carrying the mutated allele (GC+CC) at the mean follow-up showed an event probability of 36.1%, whereas the wild population (GG) presented only 23.4%. The Log-Rank test showed significant differences between the two curves (p=0.019).
Conclusion
The mutated TCF21 variant can provide a new marker to identify patients at high cardiovascular risk and may representa potential target for gene therapy in future.

Abstract
Abstract
Background
The risk for Coronary Artery Disease (CAD) is determined by both genetic and environmental factors, as well as by the interaction between them. It is estimated that genetic factors could account for 40% to 55% of the existing variability among the population (inheritability). Therefore, some authors have advised that it is time we integrated genetic risk scores into clinical practice.
Aim
The aim of this study was to evaluate the magnitude of the association between an additive genetic risk score (aGRS) and CAD based on the cumulative number of risk alleles in these variants, and to estimate whether their use is valuable in clinical practice.
Methods
A case-control study was performed in a Portuguese population. We enrolled 3120 participants, of whom 1687 were CAD patients and 1433 were normal controls. Controls were paired to cases with respect to gender and age. 33 genetic variants known to be associated with CAD were selected, and an aGRS was calculated for each individual. The aGRS was further subdivided into deciles groups, in order to estimate the CAD risk in each decile, defined by the number of risk alleles. The magnitude of the risk (odds ratio) was calculated for each group by multiple logistic regression using the 5th decile as the reference group (median). In order to evaluate the ability of the aGRS to discriminate susceptibility to CAD, two genetic models were performed, the first with traditional risk factors (TRF) and second with TRF plus aGRS. The AUC of the two ROC curves was calculated.
Results
A higher prevalence of cases over controls became apparent from the 6th decile of the aGRS, reflecting the higher number of risk alleles present (see figure). The difference in CAD risk was only significant from the 6th decile, increasing gradually until the 10th decile. The odds ratio (OR) for the last decile related to 5th decile (median) was 1.87 (95% CI:1.36–2.56; p<0.0001). The first model yielded an AUC=0.738 (95% CI:0.720–0.755) and the second model was slightly more discriminative for CAD risk (AUC=0.748; 95% CI:0.730–0.765). The DeLong test was significant (p=0.0002).
Conclusion
Adding an aGRS to the non-genetic risk factors resulted in a modest improvement in the ability to discriminate the risk of CAD. Such improvement, even if statistically significant, does not appear to be of real value in clinical practice yet. We anticipate that with the development of further knowledge about different SNPs and their complex interactions, and with the inclusion of rare genetic variants, genetic risk scores will be better suited for use in a clinical setting.

Abstract
Considering that optimal contact area and pressure at the tendon-bone interface are associated with better footprint repair and outcomes, the aim of this study was to compare the performance of standard double-row, transosseous equivalent (TOE), and partial articular supraspinatus tendon avulsion (PASTA) techniques for the treatment of full-thickness tears of the supraspinatus tendon using 3D finite element models. Loading consisted, alternately, in a preloading of 10 N and 20 N of the sutures. The footprint coverage of the standard double-row, TOE, and PASTA techniques was estimated to represent 19%, 30%, and 35%, respectively, of the repair area. The average contact pressures followed an opposite trend, i.e., the largest was estimated for the standard double-row technique, whereas the lowest was estimated for the PASTA technique. Despite the present study advancing the computational modelling of rotator cuff repair, and the results being consistent with the literature, its findings must be evaluated cautiously, bearing in mind its limitations.

Abstract
Risk perception assessment of COVID-19 among Portuguese Healthcare Professionals (HCP) and General Population (GPop) was evaluated in a snowball 3 403 individual's sample. 54.9% of HCP believed there is a high probability of becoming infected, in contrast with 24.0% of GPop (p <0.001) and, in more than 1/4, that this could happen to their family. Regarding prophylactic isolation, more than 70% agreed with its effectiveness. A large proportion perceived that health services are poorly prepared (50.1% GPop versus 63.5% HCP, p<0.001). Regarding Health Authorities' communication, about 60% were "moderately" satisfied. 46.7% GPop and 52.8% HCP had the opinion the pandemic could be controlled in three to six months (p=0.01).

Abstract
The filamentous fungus Neurospora crassa is a popular model organism used in a wide range of biochemical and genetic studies and vastly used in mitochondrial research. Despite the relevance of mitochondria in N. crassa biology, no method for quantification of mitochondrial DNA (mtDNA) is currently available. Quantitative real-time PCR (qPCR) is a powerful tool, with a wide range of applications, and has been used for the quantification of nucleic acids in humans and a few other species. Here we present a new qPCR assay for relative quantification of N. crassa mtDNA. Three sets of qPCR primers targeting different regions of the mitochondrial genome were tested for mtDNA quantification. The qPCR was successfully validated in N. crassa strains from different geographical locations, representing the vast genetic diversity of this species, and knockout mutant strains. Moreover the assay proved to be efficient in templates with varied amounts of mitochondria, obtained through different DNA extraction methods. The qPCR performed well in all tested samples revealing a higher amount of mtDNA than nuclear DNA in all cases. This technique will facilitate the characterization of mtDNA of N. crassa in future studies and can be used as a tool to validate methods of mitochondria isolation. SIGNIFICANCE AND IMPACT OF THE STUDY: The standardization of quantitative real-time PCR (qPCR) techniques is essential to enable and facilitate future comparisons. Neurospora crassa is a model organism with a lot of potential in different fields of study. Here we use N. crassa to develop and establish an assay to quantify mitochondrial DNA using qPCR. We tested strains with different geographical background and our data demonstrated the usefulness of this assay to quantify mitochondrial DNA in N. crassa. This technique can be useful in a wide variety of applications and in different types of studies.

Abstract
PURPOSE To make a literature review on spinal stenosis recurrence after a first surgery and edit rules to avoid this complication. METHODS We conducted two separate PUBMED searches to evaluate the revision post-stenosis and degenerative scoliosis surgery using the terms: lumbar vertebrae/surgery, spinal stenosis, spine, scoliosis and reoperation. The resulting papers were categorized into three groups: (1) those that evaluated reoperation post-simple decompression; (2) those that evaluated spinal decompression and fusion for short (3 levels or less) or long (more than 3 levels) segment spinal fusion; and (3) those diagnosing the stenosis during the surgery. RESULTS (1) We found 11 relevant papers that only looked at revision spine surgery post-laminectomy for spinal stenosis. (2) We found 20 papers looked at reoperation post-laminectomy and fusion amongst which there were two papers specifically comparing long-segment (> 3 level) and short-segment (3 or less levels) fusions. (3) In the unspecified group, we found only one article. Fifteen articles were excluded as they were not specifically looking at our objective criteria for revision surgery. In regard to revision post-adult deformity surgery, we found 18 relevant articles. CONCLUSIONS After this literature review and analysis of post-operative stenosis, it seems important to provide some advice to avoid revision surgeries more or less induced by the surgery. It looks interesting when performing simple decompression without fusion in the lumbar spine to analyse the risk of instability induced by the decompression and facet resection but also by a global balance analysis. Regarding pre-operative stenosis in a previously operated area, different causes may be evocated, like screw or cage malpositionning but also insufficient decompression which is a common cause. Intraoperatively, the use of neuromonitoring and intraoperative CT scan with navigation are useful tool in complex cases to avoid persisting stenosis. Pre-op analysis and planning are key parameters to decrease post-op problems. These slides can be retrieved under Electronic Supplementary Material.

Abstract
AIM Understand EAPD members' practices of vital bleaching for children with dental anomalies. METHODS An anonymous online survey sent via EAPD in January 2019, consisting of 13 questions with possible multiple answers and free text. RESULTS 110 responses from 24 countries were obtained. The majority worked in hospitals/universities (n = 69, 63%) or private practices (n = 50, 46%) and were specialists (n = 62, 57%) or senior academics (n = 35, 32%). Most respondents (n = 74 68%) did not provide vital bleaching for children. 88 respondents (80%) belonged to EU: of these, 46 (52%) were not aware of bleaching regulations. For respondents who provided bleaching 26 (72%) undertook home bleaching, using 10% carbamide peroxide (n = 21, 58%), most commonly for 2 weeks (n = 14, 39%), following establishment of the permanent dentition (n = 21, 58%). Deciding factors included: extent (n = 27, 75%) and shade (n = 26, 72%) of discolouration and child being teased by peers (n = 23, 64%). Main reasons for not bleaching included: concerns with side effects (n = 41; 55%) and not agreeing with bleaching (n = 23, 31%). Dentists who did not bleach managed a range of conditions, most frequently molar-incisor hypomineralisation (n = 57; 77%). The majority provided composite restorations with removal of tooth structure (n = 50; 68%) with a number opting for no treatment (n = 27, 37%). CONCLUSION This study shows wide variations in treatment of children's dental anomalies across Europe. Fears of adverse effects and personal beliefs seemed to be the main deterrents to bleaching in children. Clinicians who provided bleaching tended to opt for more conservative techniques and to take children's concerns into consideration.

Abstract
Abstract
TCF21 is a member of the basic-helix-loop-helix (bHLH) transcriptor factor family, being critical for embryogenesis of the heart, kidney and spleen. TCF21 also regulates epicardium-derived cells differentiation into smooth muscle and fibroblast lineages.
Aim
Investigate the impact of TCF21 rs12190287 in the prediction and discrimination of CAD risk, individually or into a genetic risk score (GRS) formed by a set of 13 genetic variants.
Methods
We performed a case-control study with 3050 subjects (1619 coronary patients with 53.3±8 years; 78.9% male and 1431 controls with 52.8±8 years; 76.6% male) from GENEMACOR study. We investigated all traditional risk factors (TRF), as well as 13 genetic variants from GWAS with unknown pathophysiological pathway so far, including TCF21 (rs12190287), ZC3HC1 (rs11556924), PSRC1/SORTI (rs599839), PHACTR1 (rs1332844), MIA3 (rs17465637), SMAD3 (rs17228212), ZNF259 (rs964184), ADAMTS7 (rs3825807), CDKN2B (rs4977574), 9p21.3 (rs1333049), KIF6 (rs20455), PCSK9 (rs2114580) and GJA4 (rs618675). A multiplicative genetic risk score with these 13 genetic variants (m13GRS), was calculated. Subsequently, two logistic regressions were performed; primarily with all the TRF and all the genes individually and the second with TRF and m13GRS.
Results
The first multivariate analysis shows that, besides the strong association of the TRF with CAD risk (with smoking status on the top of the list, with an OR of 3.2; p<0.0001), TCF21 rs12190287 was the most significant variant from all the studied genetic set with a CAD risk of 1.5 (95% CI: 1.1–1.9; p=0.004), followed by the well-known genetic determinant CDKN2B rs4977574 (OR=1.4; 95% CI: 1.1–1.7; p<0.002) and ZC3HC1 rs11556924 (OR=1.3; 95% CI: 1.0–1.7; p=0.034). When GRS is included to the model, all the TRF remain in the equation by the same order, and the m13GRS persisted as an independent predictor for CAD risk (OR=1.7; 95% CI: 1.4–2.0; p<0.0001).
Conclusion
TCF21 rs12190287 is a risk factor for CAD in the Portuguese population, either individually or incorporated in a m13GRS. TCF21 risk is independent from TRF. In the future, TCF21 can provide a new clues to identify patients at high cardiovascular risk and become a potential target for gene therapy.

Abstract
Abstract
Introduction
Previous research reported that LPA gene is a strong and independent predictor of CAD in non-diabetic patients but not in patients with type 2 diabetes. These results suggest that LPA gene might contribute less to CAD risk in patients with T2DM than in general population.
Objective
Investigate, in our population, the association between LPA gene CT variant and CAD risk among diabetic patients.
Methods
3050 individuals (1619 coronary patients and 1431 controls) were genotyped for LPA rs3798220 TT/CT. Pearson's chi-squared test was applied to evaluate the association between LPA variants and CAD, firstly, in the general population and, secondly, in the group of patients with T2DM (n=735). Multivariate logistic regression was performed with LPA CT variant and 6 traditional risk factors (TRF) (smoking, dyslipidemia, diabetes, hypertension, family history of CAD and physical inactivity) in both general and diabetic population.
Results
In total population, LPA CT variant was found to be strongly and significantly associated with CAD with an OR of 2.32 (95% CI: 1.56–3.45; p<0.0001). However, this association was less pronounced in the diabetic population with a CAD risk of 1.38 (95% CI: 0.56–3.43) without statistical significance (p=0.485). In the presence of 6 major TRF, multivariate analysis showed that LPA CT remained a strong and independent predictor of CAD risk (OR= 2.34; 95% CI: 1.52–3.62; p<0.0001). In diabetic population, LPA was no longer an independent predictor for CAD by multivariate analysis.
Conclusions
Our results show that the effect of LPA gene on CAD risk among diabetic patients might be different from that in the general population. Diabetes status is such a strong risk factor that may attenuate the genetic effects of LPA on CAD risk. This may indicate a complex role of Lp (a) and diabetes interaction in cardiometabolic diseases.

Abstract
Abstract
Introduction
Coronary artery disease (CAD) is the leading cause of death worldwide, placing a major economic and resource burden on health and public health systems, so efforts are being made to accurately predict risk for major adverse cardiac events (MACE). The field of risk prediction and CAD prevention continues to evolve with the identification of novel risk factors and biomarkers, such as lipoprotein a [Lp)a]. Almost 20% of the population has elevated circulating levels of Lp(a), which is recognized as an independent risk factor for CAD, stroke, peripheral arterial disease, and aortic stenosis. Importantly, studies showed that this was particularly true for women.
Objective
To evaluate if the elevation of Lp(a) is associated with MACE in female, male or both.
Materials and methods
Case control study of 3050 subjects from the GENEMACOR study population. In female population (n=676): cases were 341 patients with at least one >75% coronary stenosis (median age 55.7±7.2) and 335 normal controls (median age 55.8±6) adjusted by age with cases. In male population (n=2374): 1278 patients with at least one >75% coronary stenosis (median age 52.7±8) and 1096 controls (median age 51.9±8) also adjusted by age. χ2 and T student tests were used to analyze the demographic, laboratorial, angiographic and anthropometric characteristics of the population. Lipoprotein (a) was determined by immunoturbidimetry. High Lp(a) level was considered if superior to 30 mg/dl. Logistic regression was used to evaluate Lp(a) as a risk factor for CAD in total, female and male populations.
Results
In female population 44.0% patients vs 21.2% controls (p<0.000) had Lp(a)>30mg/dl. In male population 39.4% patients vs 23.8% controls (p<0.000) had Lp(a)>30mg/dl. In total population Lp(a)>30mg/dl was a predictor for CAD (OR 2.24, 95% CI: 1.91–2.62, p<0.0001). Analyzing by gender, Lp(a)>30mg/dl was also a predictor for CAD either in male (OR 2.08, 95% CI: 1.74–2.5, p<0.0001) or female population (OR 2.92, 95% CI: 2.08–4.09, p<0.0001).
Conclusions
As opposed to other studies, in our population elevated Lp(a) levels (>30mg/dl) were associated with elevated CAD risk, in both men and women. We conclude that Lp(a) can be considered an independent risk factor for CAD disease in our population, and further strategies for Lp(a) reduction may indeed translate in improved outcomes in CAD disease.

Abstract
Abstract
Type 2 Diabetes (T2D) is a risk factor for dysregulation of glomerular filtration rate (GFR) and albuminuria. However, it remains unclear whether this association is only causal. Genetic variants are inherited independent of potential confounding factors and represent a lifetime exposure.
Aim
Investigate whether the reduction of GFR is a direct consequence of T2D or there are other genetic mechanisms involved in the pathophysiology of the evolution to chronic kidney disease.
Methods
Cross-sectional study with a total of 2579 individuals was performed, of which 735 patients had T2D. Subjects were classified as `'diabetic” if they were taking oral anti-diabetic medication or insulin or if their fasting plasma glucose was higher than 7.0 mmol/l or 126 mg/dl. Within the diabetic group, we considered those with (n=63) and without (n=627) decreased GFR. GFR was calculated through the Cockcroft and Gault formula and decreased GFR was defined as GFR<60 ml/min/1.73m2. Twenty-four genetic variants associated with T2D, metabolic syndrome, dyslipidemia and hypertension were investigated for its impact on GFR, namely: MTHFR 677 and 1298; MTHFD1L; PON 55, 192 and 108; ATIR A/C; AGT M235T; ACE I/D; TCF7L2; SLC30A8; MC4R; ADIPOQ; FTO; TAS2R50; HNF4A; IGF2BP2; PPARG; PCSK9; KIF6; ZNF259; LPA; APOE; PSRS1. Risk factors for decreased GFR were also evaluated (essential hypertension, glycaemia >120 mg/ml, dyslipidemia, alcohol consumption, CAD diagnosis). A logistic regression was performed firstly with the risk factors solely; and secondly adding the genetic variants in order to evaluate the independent predictors of progression to renal failure in T2D.
Results
After the first multivariate logistic regression with all the risk factors for decreased GFR, only CAD remained in the equation, showing to be an independent risk factor for progression to renal failure, in T2D (OR=4.17; 95% CI: 1.64–10.59; p=0.003). In the second logistic regression, including risk factors and the genetic variants, only ZNF259 rs964184 showed an independent and significant association with the risk of decreased GFR (OR=3.03; 95% CI: 1.06–8.70; p=0.039).
Conclusion
This study shows that the variant ZNF259 rs964184 is associated with decreased kidney function, independently of other risk factors. This finding needs further investigation to clarify the genetic mechanism behind the association of rs964184 with decreased GFR, in Type 2 diabetes.

Abstract
Abstract
Introduction
Coronary artery disease (CAD) is a multifactorial process with substantial genetic contribution. However, genetic predisposition among patients with a different number of lifestyle factors and premature CAD, remains a complex and thoroughly unexplored topic.
Objective
To evaluate, in a young population, the importance of conventional risk factors as well as of a genetic risk score in the appearance of CAD.
Methods
A case-control study was conducted with 1075 patients from the GENEMACOR study population, under 50 years-old (555 cases, 86.8% male, mean age 44.1±4.9 years and 520 controls, 86.2% male, mean age 44.3±4.8 years). Univariate analysis addressed the association of different modifiable risk factors with premature CAD. Genetic risk score (GRS) was computed comprising 33 genetic risk variants in a multiplicative method. GRS was evaluated according to the number of traditional risk factors and risk for premature CAD was estimated and its independent predictive value estimated by logistic regression.
Results
72.6% of patients had ≥3 risk factors vs 31.2% of controls (p<0.0001). In comparison with having no risk factors (rf), patients with 1 rf had an OR of 2.79 (1.19–6.53; p=0.015), patients with 2 risk factors had a OR of 6.87 (3.03–15–57, p<0.0001) and patients with 3 modifiable risk factors had a OR of 24.17 (10.87–53.73, p<0.0001) – graph 1. In this young population, mean GRS level was consistently higher among patients with coronary artery disease comparing with a healthy population (0.6±0.6 vs 0.4±0.4, p<0.0001, respectively) – graph 2. GRS in multivariate analysis, proved to be an independent predictor for premature CAD (OR 1.71, CI95% 1.25–2.34, p=0.001).
Conclusion
In our population, GRS was an independent predictor for premature CAD. In young patients with ≥3 risk factors, genetics play a less decisive role in the development of CAD. Even in young patients, modifiable risk factors should be addressed aggressively as they may represent a higher burden than genetic predisposition itself.

Abstract
Abstract
Introduction
The complex interaction between genes and environmental factors contribute to individual-level risk of coronary artery disease (CAD), often resulting in premature CAD. The role for genetic risk scores in premature CAD is still controversial.
Objective
To evaluate the importance of conventional risk factors and of a genetic risk score in younger and older patients with coronary artery disease
Methods
From a group of 1619 pts with angiographic documented CAD from the GENEMACOR study, we selected 1276 pts admitted for ACS and analysed them in 2 groups (group A: ≤50 years, n=491 pts, 87.2% male, mean age 44±4.9 and group B: >50 years, n=785 pts, 75.2% male, mean age 57±4.2). Univariate analysis was used to characterize the traits of each group and we used ROC curves and respective AUCs to evaluate the power of genetics in the prediction of CAD, through a Genetic Risk Score (GRS).
Results
99.3% of the young patients had at least one modifiable risk factor, 18.4% had 2 modifiable risk factors and 75.2% had 3 or more modifiable risk factors. The pattern of risk factors contributing to CAD were different among groups: family history (A: 27.5%, B: 21.4%, p=0.015) and smoking habits (A: 64.8%, B: 42.9%, p<0.001) were more frequent among patients under 50, and traditional age-linked factors like hypertension (A: 58%, B: 75.7%, p<0.001), diabetes (A: 21.6%, B: 38.6%, p<0.001) were more common in the older group. Acute ST-elevation myocardial infarction was more frequent among the young (A: 55.4%, B: 47.4%, p=0.006), as non-ST clinical presentation was higher among elder patients. Regarding angiographic presentation, single vessel CAD was higher in group A (A: 50.3%, B: 40.9%, p<0.001), while multivessel diasease was higher in group B (A: 33.3%, B: 53.9%, p<0.001). At a mean follow-up of 5 years, older patients had a worst prognosis, registering a higher rate of cardiovascular death (A: 4.1%, B: 8.6%, p=0.002) and higher MACE (A: 26.8%, B: 31%, p=0.128),. Adding the genetic risk score (GRS), we achieved only a slight improvement in the AUC for predicting CAD (0.796->0.805, p=0.0178 and 0.748->0.761, p=0.0007 in patients under and over 50, respectively).
Conclusion
Coronary artery disease is not all the same, as premature CAD shares a unique and specific pattern of risk factors, clinical presentation, angiographic severity and prognosis. Genetics should not be used as an excuse to justify premature CAD, as there is frequently more than one potentially reversible risk factor present even in young patients and the additive predictive value of GRS is modest.

Abstract
BACKGROUND New implant designs, such as resurfacing and stemless implants, have been developed to improve the long-term outcomes of the shoulder arthroplasty. However, it is not yet fully understood if their influence on the bone load distribution can compromise the long-term stability of the implant due to bone mass changes. Using three-dimensional finite element models, the aim of the present study was to analyse the bone remodelling process of the humerus after the introduction of resurfacing and stemless implants based on the Global C.A.P. and Sidus Stem-Free designs, respectively. METHODS The 3D geometric model of the humerus was generated from the CT data of the Visible Human Project and the resurfacing and stemless implants were modelled in Solidworks. Considering a native humerus model, a humerus model with the resurfacing implant, and a humerus model with the stemless implant, three finite element models were developed in Abaqus. Bone remodelling simulations were performed considering healthy and poor bone quality conditions. The loading condition considered comprised 6 load cases of standard shoulder movements, including muscle and joint reaction forces estimated by a multibody model of the upper limb. FINDINGS The results showed similar levels of bone resorption for the resurfacing and stemless implants for common humeral regions. The regions underneath the head of the resurfacing implant, unique to this design, showed the largest bone loss. For both implants, bone resorption was more pronounced for the poor bone quality condition than for the healthy bone quality condition. INTERPRETATION The stemless implant lost less density at the fixation site, which might suggest that these implants may be better supported in the long-term than the resurfacing implants. However, further investigation is necessary to allow definite recommendations.

Abstract
BACKGROUND Most studies on academic cheating rely on self-reported questionnaires and focus on the individual, overlooking cheating as a group activity. The aim of this study is to estimate the true prevalence of cheating/anomalies among medical students using a statistical index developed for this purpose, and to explore the existence of social networks between anomalies in students' results. METHODS Angoff's A index was applied to a sample of 30 written examinations, with a total of 1487 students and 7403 examinations taken, from the 2014/2015 academic year of the Faculty of Medicine of the University of Porto to detect anomaly pairs. All analyses are within the same academic year and not across years. Through simulations, the sensitivity and specificity of the statistical method was determined, and the true prevalence of anomalies/cheating was estimated. Networks of anomaly pairs were created to search for patterns and to calculate their density. RESULTS The percentage of students who cheated at least once increased with the year of medical school, being lowest in the first year (3.4%) and highest in the fifth (17.3%). The year of medical school was associated with anomalies (p < 0.05). The network's density was also lowest in the first year (1.12E-04) and highest in the fifth (8.20E-04). The true prevalence of anomalies was estimated to be 1.85% (95%CI: 1.07-3.20%). CONCLUSIONS These findings suggest that some students are involved in social networks of cheating, which grow over time, resulting in an increase of anomalies/cheating in later academic years.
