Management of a Rare Case of Multiple Coronary Artery Fistulas Associated with Ascending Aortic and Root Aneurysm: Case Report and Review of Literature.

Coronary artery fistulas draining into the left ventricle is a rare finding. They can be associated with other congenital cardiac anomalies like ventricular septal defect or tetralogy of Fallot. While most of them are asymptomatic, they can lead to severe cardiac complications like infective endocarditis, heart failure, or myocardial ischemia. Symptomatic coronary artery fistulas can be managed surgically or percutaneously. We present a case of a 61-year-old male patient with both left anterior descending artery and right coronary artery fistulas draining into the left ventricle associated with ascending aorta and root aneurysm. Preoperative assessment for myocardial ischemia and the size and location of the fistulas was performed. The echocardiography stress test was negative. Surgery consisted of replacement of the ascending aorta and reconstruction of the noncoronary sinus with a Dacron patch with aortic valve preservation and no intervention for the coronary artery fistulas. The surgical strategy was adapted for cardioplegia administration to compensate for the volume of coronary blood drained into the left ventricle and for better protection of the distal myocardium.

Investigation of the Association between Bilateral Selective Anterograde Cerebral Perfusion and Postoperative Ischemic Stroke in Obese Patients with Emergency Surgery for Acute Type A Aortic Dissection.

Background and objectives: The relationship between cerebral perfusion and new postoperative ischemic stroke in obese patients is not well defined. The aim of this study was to investigate the association between selective bilateral anterograde cerebral perfusion and new postoperative ischemic stroke in obese patients with emergency surgery for acute type A aortic dissection. Materials and methods: A total of 292 patients with emergency surgery for acute type A aortic dissection were included in this study. Patients with hemorrhagic stroke or ischemic stroke with severe neurological dysfunction at admission that were not candidates for surgery; patients who died in the first 48 h after intensive care admission and patients with incomplete medical records were excluded. Results: The mean age was 59.42 ± 10.68 years and the mean Euroscore was 9.12 ± 1.63. Obesity was present in 76.4%, the incidence of new postoperative ischemic stroke was 27.5%, and the postoperative mortality rate was 26.7%. The mean cardiopulmonary bypass time was 206.81 ± 75.48 min, the aortic cross-clamp time was 118.2 ± 46.42 min, and 90% of cases required cerebral perfusion. The mean cerebral perfusion time was 30.8 ± 24.41 min. Obese patients had a higher frequency of in-hospital death (p = 0.009), smoking (p = 0.036), hypertension (p = 0.023), left common carotid artery dissection (p < 0.001), right common carotid artery dissection (p = 0.029), femoral artery cannulation (p = 0.026), aortic root replacement (p = 0.009), aortic valve replacement (p = 0.005) and early reintervention for bleeding (p = 0.004). Using logistic regression, selective bilateral anterograde cerebral perfusion over 40 min in obese patients was independently associated with new postoperative ischemic stroke (OR = 2.35; 95%CI = 1.36-4.86; p = 0.021). Conclusions: A patient-tailored strategy for cerebral perfusion should be considered in obese patients, considering the high atheromatous burden of the supra-aortic vessels in these patients and the potential risk of atheromatous embolization associated with this technique.

Clinical and Biological Data in Patients with Pancreatic Cancer vs. Chronic Pancreatitis-A Single Center Comparative Analysis.

INTRODUCTION: In some patients with chronic pancreatitis, the diagnosis of pancreatic cancer can be missed. The objective of the study was to identify clinical and paraclinical data with statistical significance in the differential diagnosis between chronic pancreatitis and pancreatic cancer. MATERIALS AND METHODS: We conducted a retrospective, observational study on a cohort of 120 patients hospitalized over 3 years. The patients were equally distributed in two groups: group A, with 60 patients with pancreatic cancer, and group B, with 60 patients with chronic pancreatitis. The statistical analysis was carried out by using the R program. RESULTS: The comparative analysis of pancreatic cancer vs. chronic pancreatitis revealed a stronger link between pancreatic cancer, female gender (p = 0.001) and age over 60 years (p < 0.001). Patients with pancreatic cancer had higher serum values of aspartate aminotransferase (p 0.005), alanine aminotransferase (p 0.006), total bilirubin (p < 0.001), direct bilirubin (p < 0.001), alkaline phosphatase (p 0.030), C-reactive protein (p = 0.049) and uric acid (p 0.001), while patients with chronic pancreatitis presented slightly higher values of amylase (p 0.020) and lipase (p 0.029). CONCLUSIONS: Female gender, advanced age, elevated aminotransferases, cholestasis markers and uric acid were associated with a higher probability of pancreatic cancer.

The Profile and All-Cause In-Hospital Mortality Dynamics of St-Segment Elevation Myocardial Infarction Patients during the Two Years of the COVID-19 Pandemic.

During the coronavirus pandemic 2019 (COVID-19), some studies showed differences in the profile of subjects presenting with acute coronary syndromes as well as in overall mortality due to the delay of presentation and other complications. The purpose of this study was to compare the profile and outcomes, with emphasis on all-cause in-hospital mortality, of ST-elevation myocardial infarction (STEMI) subjects presenting to the emergency department during the pandemic period compared with a control group from the previous year, 2019. The study enrolled 2011 STEMI cases, which were divided into two groups-pre-pandemic (2019-2020) and pandemic period (2020-2022). Hospital admissions for a STEMI diagnosis sharply decreased during the COVID-19 period by 30.26% during the first year and 25.4% in the second year. This trend was paralleled by a significant increase in all-cause in-hospital mortality: 11.5% in the pandemic period versus 8.1% in the previous year. There was a significant association between SARS-CoV-2 positivity and all-cause in-hospital mortality, but no correlation was found between COVID-19 diagnosis and the type of revascularization. However, the profile of subjects presenting with STEMI did not change over time during the pandemic; their demographic and comorbid characteristics remained similar.

Clinical characteristics and factors associated with ICU mortality during the first year of the SARS-Cov-2 pandemic in Romania: A prospective, cohort, multicentre study of 9000 patients.

BACKGROUND: The epidemiology of critically ill patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be different worldwide. Despite similarities in medicine quality and formation, there are also significant differences concerning healthcare and ICU organisation, staffing, financial resources and population compliance and adherence. Large cohort data of critically ill patients from Central and Eastern Europe are also lacking. OBJECTIVES: The study objectives were to describe the clinical characteristics of patients admitted to Romanian ICUs with SARS-CoV-2 infection and to identify the factors associated with ICU mortality. DESIGN: Prospective, cohort, observational study. SETTING: National recruitment, multicentre study, between March 2020 to March 2021. PATIENTS: All patients with SARS-CoV-2 infection admitted to Romanian ICUs were eligible. There were no exclusion criteria. INTERVENTION: None. MAIN OUTCOME MEASURE: ICU mortality. RESULTS: The statistical analysis included 9058 patients with definitive ICU outcome. The multivariable mixed effects logistic regression model found that age [odds ratio (OR) 1.27; 95% confidence interval (CI), 1.23 to 1.31], male gender (OR 1.21; 95% CI 1.05 to 1.4), medical history of neoplasia (OR 1.74; 95% CI, 1.36 to 2.22), chronic kidney disease (OR 1.54; 95% CI, 1.27 to 1.88), type II diabetes (OR 1.23; 95% CI, 1.06 to 1.43), chronic heart failure (OR 1.24; 95% CI, 1.03 to 1.49), dyspnoea (OR 1.3; 95% CI, 1.1 to 1.5), SpO2 less than 90% (OR 3; 95% CI, 2.5 to 3.5), admission SOFA score (OR 1.07; 95% CI, 1.05 to 1.09), acute respiratory distress syndrome (ARDS) on ICU admission (OR 1.35; 95% CI, 1.1 to 1.63) and the need for noninvasive (OR 1.8, 95% CI, 1.5 to 1.22) or invasive ventilation (OR 28; 95% CI, 22 to 35) and neuromuscular blockade (OR 3.5; 95% CI, 2.6 to 4.8), were associated with larger ICU mortality.Higher GCS on admission (OR 0.81; 95% CI, 0.79 to 0.83), treatment with hydroxychloroquine (OR 0.78; 95% CI, 0.64 to 0.95) and tocilizumab (OR 0.58; 95% CI, 0.48 to 0.71) were inversely associated with ICU mortality. CONCLUSION: The SARS-CoV-2 critically ill Romanian patients share common personal and clinical characteristics with published European cohorts. Public health measures and vaccination campaign should focus on patients at risk.

In-stent restenosis in acute coronary syndrome-a classic and a machine learning approach.

Background: In acute coronary syndrome (ACS), a number of previous studies tried to identify the risk factors that are most likely to influence the rate of in-stent restenosis (ISR), but the contribution of these factors to ISR is not clearly defined. Thus, the need for a better way of identifying the independent predictors of ISR, which comes in the form of Machine Learning (ML). Objectives: The aim of this study is to evaluate the relationship between ISR and risk factors associated with ACS and to develop and validate a nomogram to predict the probability of ISR through the use of ML in patients undergoing percutaneous coronary intervention (PCI). Methods: Consecutive patients presenting with ACS who were successfully treated with PCI and who had an angiographic follow-up after at least 3 months were included in the study. ISR risk factors considered into the study were demographic, clinical and peri-procedural angiographic lesion risk factors. We explored four ML techniques (Random Forest (RF), support vector machines (SVM), simple linear logistic regression (LLR) and deep neural network (DNN)) to predict the risk of ISR. Overall, 21 features were selected as input variables for the ML algorithms, including continuous, categorical and binary variables. Results: The total cohort of subjects included 340 subjects, in which the incidence of ISR observed was 17.68% (n = 87). The most performant model in terms of ISR prediction out of the four explored was RF, with an area under the receiver operating characteristic (ROC) curve of 0.726. Across the predictors herein considered, only three predictors were statistically significant, precisely, the number of affected arteries (≥2), stent generation and diameter. Conclusion: ML models applied in patients after PCI can contribute to a better differentiation of the future risk of ISR.

Identification of Risk Genes Associated with Myocardial Infarction-Big Data Analysis and Literature Review.

Acute myocardial infarction occurs when blood supply to a particular coronary artery is cut off, causing ischemia or hypoxia and subsequent heart muscle destruction in the vascularized area. With a mortality rate of 17% per year, myocardial infarction (MI) is still one of the top causes of death globally. Numerous studies have been done to identify the genetic risk factors for myocardial infarction, as a positive family history of heart disease is one of the most potent cardiovascular risk factors. The goal of this review is to compile all the information currently accessible in the literature on the genes associated with AMI. We performed a big data analysis of genes associated with acute myocardial infarction, using the following keywords: "myocardial infarction", "genes", "involvement", "association", and "risk". The analysis was done using PubMed, Scopus, and Web of Science. Data from the title, abstract, and keywords were exported as text files and imported into an Excel spreadsheet. Its analysis was carried out using the VOSviewer v. 1.6.18 software. Our analysis found 28 genes which are mostly likely associated with an increased risk for AMI, including: PAI-1, CX37, IL18, and others. Also, a correlation was made between the results obtained in the big data analysis and the results of the review. The most important genes increasing the risk for AMI are lymphotoxin-a gene (LTA), LGALS2, LDLR, and APOA5. A deeper understanding of the underlying functional genomic circuits may present new opportunities for research in the future.

Diastolic versus Systolic Left Ventricular Dysfunction as Independent Predictors for Unfavorable Postoperative Evolution in Patients with Aortic Regurgitation Undergoing Aortic Valve Replacement.

Background and Objectives: Chronic severe aortic valve disease is associated with important changes in left ventricle (LV) performance associated with eccentric or concentric LV hypertrophy. We aimed to assess the immediate prognostic implications of the type of the LV diastolic filling pattern (LVDFP) compared with LV systolic performance in patients with severe aortic regurgitation (AR) undergoing aortic valve replacement (AVR) and to define the independent echographic predictors for the immediate and long-term prognoses. Materials and Methods: We performed a prospective study enrolling 332 AR patients undergoing AVR, divided into two groups: Group A­201 pts with normal LV systolic function, divided into two subgroups (A1: 129 pts with a nonrestrictive LVDFP and A2: 72 pts with restrictive LVDFP), and Group B­131 pts with LV systolic dysfunction (LV ejection fraction LVEF < 50%), divided into two subgroups (B1: 83 pts with a nonrestrictive LVDFP and B2: 48 pts with restrictive LVDFP). Results: The early postoperative mortality rate was higher in patients with a restrictive LVDFP (11.12% in A2 and 12.5% in B2) compared with normal LV filling (2.32% in A1 and 7.63% in B1, p < 0.0001), regardless of the LVEF. The restrictive LVDFP­defined by at least one of the following echographic parameters: an E/A > 2 with an E wave deceleration time (EDt) < 100 ms; an isovolumetric relaxation time (IVRT) < 60 ms; or an S/D ratio < 1 in the pulmonary vein flow­was an independent predictor for early postoperative mortality, increasing the relative risk by 8.2-fold. Other independent factors associated with early poor prognosis were an LV end-systolic diameter (LVESD) > 58 mm, an age > 75 years, and the presence of comorbidities (chronic obstructive pulmonary disease-COPD or diabetes mellitus). On a medium-term, an unfavorable evolution was associated with: an age > 75 years (RR = 8.1), an LV end-systolic volume (LVESV) > 95 cm3 (RR = 6.7), a restrictive LVDFP (RR = 9.8, p < 0.0002), and pulmonary hypertension (RR = 8.2). Conclusions: The presence of a restrictive LVDFP in patients with AR undergoing AVR is associated with both increased early and medium-term mortality rates. The LV diastolic function is a more reliable parameter for prognosis than LV systolic performance (RR 9.2 versus 2.1). Other independent predictors for increased early postoperative mortality rate were: an age > 75 years, an LVESD > 58 mm, and comorbidities (diabetes mellitus, COPD), and for unfavorable evolution at 2 years postoperatively: an age > 75 years, an LVESV > 95 cm3, and severe pulmonary hypertension.

Delayed Surgical Management of Acute Type A Aortic Dissection in a Patient with Recent COVID-19 Infection and Post-COVID-19 Bronchopneumonia-Case Report and Review of Literature.

Ever since it was first described in 1760, acute type A aortic dissection has created difficulties in its management. The recent COVID-19 pandemic revealed that extrapulmonary manifestations of this condition may occur, and recent reports suggested that aortic dissection may be amongst them since it shares a common physiopathology, that is, hyper-inflammatory syndrome. Cardiac surgery with cardiopulmonary bypass in the setting of COVID-19-positive patients carries a high risk of postoperative respiratory failure. While the vast majority accept that management of type A aortic dissection requires urgent surgery and central aortic therapy, there are some reports that advocate for delaying surgery. In this situation, the risk of aortic rupture must be balanced with the possible benefits of delaying urgent surgery. We present a case of acute type A dissection with COVID-19-associated bronchopneumonia successfully managed after delaying surgery for 6 days.

Diagnostic and Therapeutic Characteristics in Patients with Pneumotorax Associated with COVID-19 versus Non-COVID-19 Pneumotorax.

Introduction: Pneumothorax is a condition that usually occurs in thin, young people, especially in smokers. It is an unusual complication of COVID-19 disease that can be associated with worse results. This disease can occur without pre-existing lung disease or without mechanical ventilation. Materials and Methods: We present a monocentric comparative retrospective study of diagnostic and treatment analysis of two groups of patients diagnosed with COVID-19 and non-COVID-19 pneumothorax. All patients included in this study underwent surgery in a thoracic surgery department. The study was conducted over a period of 18 months. It included 34 patients with COVID-19 pneumothorax and 42 patients with non-COVID-19 pneumothorax. Results: The clinical symptoms were more intense in patients with COVID-19 pneumothorax. We found that the patients with COVID-19 had significantly more respiratory comorbidities. Diagnostic procedures include chest CT exam for both groups. Laboratory findings showed that increasing values for the analyzed data were consistent with the deterioration of the general condition and the appearance of pneumothorax in the COVID-19 group. The therapeutic attitude regarding the non-COVID-19 group was to eliminate the air from the pleural cavity and surgical approach to the lesion that determined the occurrence of pneumothorax. The group of patients with COVID-19 pneumothorax received systemic treatment, and only minimal pleurotomy was performed. The surgical approach did not alter patients' survival. Conclusions: Careful monitoring of the patient's clinic and laboratory tests evaluating the degradation of the lung parenchyma, correlated with the imaging examination (chest CT) is mandatory and reduces COVID-19 complications. Early imaging examination starts an effective diagnosis and treatment management. In severe COVID-19 pneumothorax cases, the pneumothorax did not influence the evolution of COVID-19 disease. When we found that the general condition worsened with the rapid progression of dyspnea and the deterioration of the general condition, and we found that it represented the progression or recurrence of pneumothorax.

The EXIMIOUS project-Mapping exposure-induced immune effects: connecting the exposome and the immunome.

Immune-mediated, noncommunicable diseases-such as autoimmune and inflammatory diseases-are chronic disorders, in which the interaction between environmental exposures and the immune system plays an important role. The prevalence and societal costs of these diseases are rising in the European Union. The EXIMIOUS consortium-gathering experts in immunology, toxicology, occupational health, clinical medicine, exposure science, epidemiology, bioinformatics, and sensor development-will study eleven European study populations, covering the entire lifespan, including prenatal life. Innovative ways of characterizing and quantifying the exposome will be combined with high-dimensional immunophenotyping and -profiling platforms to map the immune effects (immunome) induced by the exposome. We will use two main approaches that "meet in the middle"-one starting from the exposome, the other starting from health effects. Novel bioinformatics tools, based on systems immunology and machine learning, will be used to integrate and analyze these large datasets to identify immune fingerprints that reflect a person's lifetime exposome or that are early predictors of disease. This will allow researchers, policymakers, and clinicians to grasp the impact of the exposome on the immune system at the level of individuals and populations.

Hemorrhagic Cardiac Tamponade-An Unusual Threat in the COVID-19 Recovery Phase.

Cardiac tamponade is a rare presentation in patients with COVID-19, which may be induced by the associated exacerbated inflammatory response. The onset of cardiac tamponade may be concomitant with the acute phase of the disease or may develop subsequently as a new health condition secondary to the disease. We report four cases of cardiac tamponade that occurred late after the acute phase of the disease. One of them may be considered a post-acute complication of the disease, and three of them may be classified as a new health condition induced by COVID-19. Only two cases had a history of severe respiratory distress due to COVID-19. In all four cases, pericardiocentesis was imposed, and surprisingly, in every case, hemorrhagic fluid was evacuated. In this case, series, immune-mediated etiology is supported by histopathological results, where the main identified feature was fibrous pericarditis with inflammatory infiltrate. Only one patient included in this report died, and three of them were discharged after anti-inflammatory treatment was initiated.

The Effectiveness of Antiplatelet Therapy and the Factors Influencing It in Patients with Acute Coronary Syndrome before and during the COVID-19 Pandemic.

Background and Objectives: Dual antiplatelet therapy (DAPT) is essential in the treatment of patients with acute coronary syndrome (ACS). The objective of this study was to evaluate the effectiveness of antiplatelet medication in our practice and to investigate the factors that influence it. Materials and Methods: A prospective cohort observational study was conducted, in which 193 patients with ACS were enrolled. The patients were stented in the catheterization laboratory between May 2019 and October 2020, before and during the COVID-19 pandemic, and were receiving DAPT. Their platelet functions were tested using a Multiplate Analyzer. In addition to this, clinical data, demographics, laboratory tests, and cardiovascular risk factors were also analyzed. Results: 43.46% of the patients treated with aspirin were found to be resistant to it. This phenomenon was more common in men (48.17% vs. 31.48%, p = 0.036), and it was associated with being under the age of 50 (OR: 2.08; 95% CI: 1.11-3.90) and weighing over 70 kg (OR: 3.00; 95% CI: 1.21-7.40). Most of the patients treated with clopidogrel were in the optimal treatment window, while about half of the patients treated with ticagrelor had an exaggerated pharmacological response. Among the laboratory parameters, leukocytosis and platelet count were found to be determinants of platelet reactivity for both the aspirin and ticagrelor treatments. Conclusions: Many patients treated with antiplatelet agents are outside of the treatment window. The results obtained showed that low doses of gastro-resistant aspirin tablets are ineffective, and their efficacy can be influenced by various clinical and laboratory factors. Patients receiving ticagrelor have significantly reduced platelet reactivity, influenced only by certain laboratory indicators. The pandemic significantly influenced the results of the platelet aggregation tests only in patients treated with clopidogrel.

Surgical Treatment in a High-Risk Pulmonary Embolism: Case Report.

We present the case of a 35-year-old woman who had a high-risk pulmonary embolism (according to ESC risk stratification for pulmonary embolism) after she had undergone a Caesarion section. Postoperatively, she presented with acute left lower limb pain, swelling and erythema. A diagnosis was made of deep vein thrombosis (DVT) of the ilio-femoral and popliteal veins. She was started on anticoagulant therapy, which proved to be inefficient, the patient developing a left calf and thigh oedema and shortness of breath. A CT scan revealed high-risk embolus located in the right atrium and through the tricuspid valve. The decision was made to refer her to a cardiovascular surgeon. During her preoperative evaluation, the patient became hemodynamically unstable and was rushed into the operating room, severely desaturated, bradycardic, without consciousness, with severe hypotension. On the basis of the severe state of the patient and the CT scan findings we performed an emergency pulmonary embolectomy, with the patient on cardio-pulmonary by-pass, without cross-clamping the aorta, using a modified Trendelenburg procedure. This case supports using open pulmonary embolectomy for patients with hemodynamic instability on the basis of clinical diagnosis.

The Many Lives of a Complex Marfan Syndrome Patient: Staged Therapeutic Decisions.

We present a complex Marfan case, with previous type A aortic dissection, subsequent progressing aortic arch aneurysm, type B chronic aortic dissection, and Barlow disease with severe mitral regurgitation, all expressions of the same phenotype, all needing staged complex surgical therapies. (Level of Difficulty: Intermediate.).

Native Valve Infective Endocarditis - the Postoperative Results and Role of the Endocarditis Team. A Single Center Experience.

Background: Infective endocarditis (IE) may present with quite different aspects. Consequently, it's management involves a collaborative approach between several specialties. We analyzed the timing of surgery and the role of the "Endocarditis Team" in patients with IE. Methods: The medical records of patients operated for IE in our center during an 18-year period were retrospectively analyzed for the demographic data, causative agent, imagistic features of the affected valve and systemic lesion extension and postoperative results. Results: Patients age ranged between 7 and 84 years, and in many cases (55.88%) the etiology remained unidentified. The early postoperative complications were not significantly higher in patients operated in emergency compared to those with elective surgery. The overall early postoperative mortality rate was 14.05%, significantly lower in the elective surgery cases (p = 0.001). The long-term follow-up for patients operated between 2008 and 2017 showed a late postoperative death rate of 17.8% (34 patients). Conclusions: Emergency surgery for patients with native valve IE provides in most cases a good chance for a cure, despite the relatively high frequency of postoperative complications and rate of postoperative death. The advances in pre- and post-operative management of IE patients, as well as in surgical techniques and prosthetic valves seem to further improve the outcome.

Prevention of Hand Eczema among Nurse Apprentice (PREVEDERM): An Interventional Study.

BACKGROUND: Workers in the healthcare sector are at high risk of developing occupational hand eczema mainly due to frequent exposure to irritants and/or allergens. Amongst workers in healthcare, nurses are at higher risk of developing hand dermatitis. OBJECTIVES: To evaluate the effectiveness of a short educational intervention program in preventing occupational hand eczema in nurse apprentices, using two objective tools, namely TEWL and EH, and the HECSI score. METHODS: Data regarding professions, wet work exposure, activities performed during working hours, self-reported eczema were collected from 230 nurse students, divided in two study groups: the intervention and the control group (CG). The intervention group (IG) was given education about risks and proper skin care and was provided with cosmeceuticals to be used for skin care during hospital activity. The evaluation of skin properties was performed using questionnaires, HECSI score, measurement of transepidermal water loss (TEWL) and epidermal hydration (EH). RESULTS: A number of 139 apprentice nurses completed the study. Of those participants who completed the study, 19.1% from CG and 19.6% from IG reported, at T1, hand eczema in the last 3 months, while at T2 (3 months later), 59.52 % of the CG and only 11.34 % from the IG stated having eczema in the last 3 months. In the IG, results showed an improvement of CM with 17% and of TEWL with 16%, with only a 0.5% improvement of CM in CG and a marked impairment of TEWL by 33%. CONCLUSION: Hand eczema is a common occupational dermatosis affecting the medical staff, even during apprenticeship. Early preventive training programs are effective in reducing the burden of occupational contact dermatitis.

The Best Approach for Patients with Stable Coronary Disease: The Importance of a Multidisciplinary Heart Team.

Background: A multidisciplinary Heart Team (HT) is nowadays considered to be of great importance for a complete and accurate assessment of patients with stable coronary disease (CAD). This study evaluates the role of the HT approach in the selection of best therapeutic strategies for patients with stable CAD. Methods: The study included 200 patients with stable coronary artery disease. The weekly HT meetings consisted of open discussion taking into consideration the latest recommended therapies. HT outcome options included medical therapy (MT), percutaneous coronary intervention (PCI), or surgical intervention (CABG). Following HT implementation, the 1-, 3-, and 6-month outcomes in addition to the distribution of baseline characteristics were assessed. Results: The following HT strategies were implemented: PCI - 46%, CABG - 10% and MT - 44% of patients. Patients selected for surgical treatment were more likely to have multi-vessel coronary disease (p=0.011). The survival rates at 6 months according to HT strategy were 96.8% for PCI, 95% for CABG, and 94.2% for MT. Conclusions: The HT multidisciplinary decision is mandatory for optimal patient care and can prevent specialty biases. Tertiary care institutions should develop and implement interdisciplinary protocols for common CAD cases.

Is Occupational Skin Cancer More Aggressive than Sporadic Skin Cancer?

Background: Non-melanoma skin cancer (NMSC) represents the most frequently diagnosed cancer in humans. Occupational solar UV radiation exposure is associated with a higher-risk of developing NMSC, but still Romania does not acknowledge this affliction as an occupational disease. The study aims to determine if occupationally-induced NMSC is associated with more aggressive clinical and histopathological features compared to sporadic NMSC. Material and methods: A retrospective, analytical, comparative study was conducted during 2017-2019 in a University Department of Dermato-venereology in Bucharest, Romania, with focus on patients presenting with NMSC who underwent surgical excision of lesions followed by histopathological examination, classified as outdoor or indoor workers. High-risk clinical and histopathological characteristics were analysed and correlated with outdoor UV exposure. Outcomes: The study included 51 consecutive patients diagnosed with NMSC, of which 25 outdoor workers (OW) and 26 controls as indoor workers with no occupational UV exposure background. OW presented with 21 BCC and four SCC, while controls with 22 BCC and four SCC. Males were predominant in both groups and most patients came from urban environment. The mean age value was lower for the OW group compared to controls. OW had a 4.66 times higher risk of developing NMSC with aggressive location and size χ² (1, N=51) = 6.246, p=0.013, OR=4.66 (95% CI: 1.34, 16.23) and a 24-fold risk of developing NMSC with clinically poorly defined margins χ² (1, N=51) = 21.697, p<0.001, OR=24.44 (95% CI: 5.38,110.92). The risk of developing a high-risk histopathological subtype was 15 times greater for OW χ² (1, N=51) = 13.814, p<0.001, OR=15.27 (95% CI: 2.94,79.08). Moderate to severe desmoplastic reaction was 8.57 more frequent in controls χ² (1, N=51) = 12.244, p=0.001, OR=8.57 (95% CI: 2.42, 30.30). Grades 2 and 3 of actinic elastosis were significantly associated with outdoor work (χ² (1, N=51) = 33.382, p<0.001, OR=131.25 (95% CI: 13.60, 1266.37). The presence of ulceration and pigment association of tumors on the histopathological report were not significantly associated with outdoor working. Conclusion: 1. Occupational NMSC in Romania is associated with high-risk clinical features; 2. Poorly defined borders is a significant clinical high-risk factor associated with occupational UV exposure in NMSC; 3. High-risk histopathological subtypes are more frequently encountered in outdoor workers diagnosed with NMSC compared to indoor workers with no occupational UV exposure background; 4. Occupational NMSC is associated with significantly higher grades of desmoplastic reaction and of actinic elastosis compared to indoor workers.

Geometric Analysis of Type B Aortic Dissections Shows Aortic Remodeling After Intervention Using Multilayer Stents.

Recently, multilayer stents for type B aortic dissections (TBAD) have been proposed to decrease false lumen flow, increase and streamline true lumen flow, and retain branch vessel patency. We aimed to provide a protocol with standardized techniques to investigate aortic remodeling of TBAD by multilayer flow modulators (MFM) in static geometric and hemodynamic analyses. Combining existing literature and new insights, a standardized protocol was designed. Using pre- and postoperative CT scans, geometric models were constructed, lumen dimensions were calculated, computational fluid dynamics (CFD) models were composed, and velocity and pressures were calculated. Sixteen TBAD cases treated with MFM were included for analysis. For each case, aortic remodeling was analyzed using post-processing medical imaging software. After 3D models were created, geometrical anatomical measurements were performed, and meshes for finite element analysis were generated. MFM cases were compared pre- and postoperatively; true lumen volumes increased (p < 0.001), false lumen volumes decreased (p = 0.001), true lumen diameter at the plane of maximum compression (PMC) increased (p < 0.001), and false lumen index decreased (p = 0.008). True lumen flow was streamlined, and the overall fluid velocity and pressures decreased (p < 0.001 and p = 0.006, respectively). This protocol provided a standardized method to evaluate the effects of MFM treatments in TBAD on geometric analyses, PMC, and CFD outcomes.
