title: Financing for renewable energy research in Brazil: an analysis from the Energy Sector Fund

description: Abstract This article aims to analyze the contribution of the Sectorial Energy Fund to foster scientific research on renewable energies in Brazil, through a Logit model, for the period from 2011 to 2015. Estimations are carried out with additional strategies, to identify the regional effect and the contribution of research institutions on scientific production in renewable energies. The data used were obtained from the FNDCT/CNPq database and from the Lattes Curriculum of the National Council for Scientific and Technological Development (CNPq). The results obtained demonstrate an average positive marginal effect of the Sectorial Energy Fund of 2.23% on the probability of scientific production, given an increase of R$ 10,000.00 in financing. Based on the results, it is possible to justify the importance of public financing for research aimed at renewable energies.

title: Measuring structural upgrading: applying principal component analysis in a global value chain framework

description: Abstract The main objective of the article is to analyze, based on the analysis of principal components and data grouping, the relationship between structural upgrading indicators and the inclusion of those countries in the GVCs for a group of 43 countries. To achieve this objective, the study builds six upgrading indicators in three dimensions: product, process and functional. In addition to these six indicators, the study uses an indicator that measures the complexity of countries' productive structures. The results show that structural complexity has a positive and statistically significant relationship with the share of wages in income, and more capital-intensive countries also have higher levels of labor productivity and employment associated with exports. The study also shows a diversity of development patterns related to participation in GVCs and the structural upgrading process

title: Emergence of oil & gas subsea processing from a technological innovation systems perspective (1990-2019)

description: Abstract This article examines the emergence of subsea processing technologies in the global oil and gas industry during the period 1990-2019. Five subsystems related to subsea processing are considered: subsea gas compression; subsea boosting; subsea water treatment and injection; subsea separation and direct electric heating. Our analytical framework is based on the perspective of technological innovation system, focusing in the functions of the system. The system functioning analysis is based upon data from demonstration projects, scientific publications, and patents. Our main research question is: How the interactions between functions interconnect with the emergence of subsea processing in this period? We identified that system functioning have positive effects on adoption and diffusion of these new technologies. This article contributes to the debate on public policies and innovation in established sectors, as well discuss the role of developing countries in emerging technological areas.

title: A Malignant Lymphoma Growing Inside a Cardiac Mixoma: A Case Report

description: Abstract Introduction: Lymphomas arising from cardiac myxomas represent a particularly rare pathology, with only few cases reported in the literature. Case presentation: We report a complete excision of a malignant lymphoma arising from a cardiac myxoma in a 44-year-old female patient. The myxoma presented like a floating mass within the left atrium with a maximum diameter of 3.5 cm. The clinical post-operative period was uneventful and the patient was dismissed on the 6th post-operative day. Conclusion: This case reinforces the concept of radical excision of cardiac neoplasms.

title: Pediatric Heart Transplant: Initial Experience in a Tertiary Center in Brazil

description: ABSTRACT Introduction: Pediatric heart transplantation is the definitive therapy for children with end-stage heart failure. This paper describes our initial experience in pediatric heart transplantation in a tertiary center in Brazil Methods: This is a historical prospective descriptive cohort study based on a review of the medical records of children undergoing heart transplantation at Hospital de Base and Hospital da Criança e Maternidade de São José do Rio Preto. Variables were displayed as frequency, mean, or median. Statistical analysis and Kaplan-Meier actuarial curve were obtained with the aid of Microsoft® Excel® 2019 and STATSDirect version 3.3.5. Results: Between January 2010 and December 2020, ten children underwent bicaval orthotopic heart transplantation, 30% of which were under one year of age. Nine patients had end-stage heart failure (International Society for Heart and Lung Transplantation-Heart Failure D) and 50% of the recipients were transplanted under conditions of progressive clinical deterioration (Interagency Registry for Mechanically Assisted Circulatory Support ≤ 2). Forty percent of the recipients had a panel-reactive antibody &gt; 20% on virtual crossmatch. In the postoperative period, 80% of patients required high dose of inotropic support (vasoactive-inotropic score &gt; 10) for &gt; 48 hours. The death-free survival rate at 131 months was 77.1±14.4%. Most patients (88.9%) in late follow-up had an episode of active cytomegalovirus infection. Cellular rejection, with or without clinical repercussion, was present in 44.4% of the patients. Conclusion: Pediatric heart transplantation produces acceptable and feasible outcomes as definitive therapy for children with end-stage heart failure.

title: Pulmonary Thromboendarterectomy Without Circulatory Arrest

description: Abstract Introduction: Here we describe our technique and results of beating heart pulmonary thromboendarterectomy (PTE) with cardiopulmonary bypass (CPB) in four patients for treatment of chronic thromboembolic pulmonary hypertension (CTEPH). Methods: Retrospective analysis of data from patients who underwent PTE for CTEPH between January 2019 and September 2020. Patients were followed up with clinical assessment, 2D echocardiography, and computed tomography pulmonary angiogram. Results: Four patients were operated for CTEPH using our technique. Moderate tricuspid regurgitation (TR) and severe TR were found in two patients each. Severe right ventricular (RV) dysfunction was found in all cases. Thrombi were classified as Jamieson type II in three cases and type I in one case. Postoperative median direct manometric pulmonary artery (PA) pressures decreased (from 46.5 mmHg to 23.5 mmHg), median CPB time was 126 minutes, and median temperature was 33.35 °C. Mechanical ventilation was for a median of 19.5 hours. There was one re-exploration. Median intensive care unit stay was 7.5 days. There was no mortality. Postoperative 2D echocardiography revealed decrease in median PA systolic pressures (from 85 mmHg to 33 mmHg), improvement in RV function by tricuspid annular plane systolic excursion (median 14 mm vs. 16 mm), and improved postoperative oxygen saturations (88.5% vs. 99%). In follow-up (ranging between 2-15 months), all patients reported improvement in quality of life and were in New York Heart Association class I. Conclusion: With our described simple modifications, advances in perfusion, and blood conservation technologies, one can avoid the need for deep hypothermic circulatory arrest during PTE.

title: C-Reactive Protein to Albumin Ratio as A Novel Inflammatory-Based Marker for 30-Day Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement

description: Abstract Objective: We aimed to investigate whether C-reactive protein to albumin ratio (CAR) predicts the early and late mortality in patients undergoing transcatheter aortic valve replacement (TAVR). Methods: This study was retrospectively designed and includes 170 TAVR patients with a mean age of 78.4±7.1 years. Patients were divided into 2 groups as those who died and those who survived, taking into account the follow-up period. Complete blood count, serum CRP and serum albumin were obtained on admission. The CAR value of all patients was calculated and the relationship of CAR with early (≤30 days) and late mortality (&gt;30 days) was evaluated. Results: The median follow-up period was 19 [7-31] months (maximum 66 months). Early mortality was observed in 20 (11.8%) patients, whereas late mortality was observed in 39 (22.9%) patients, most of them male (61.1%, P=0.04). Non-survivors had greater CAR value, higher baseline serum CRP level and lower baseline albumin level than survivors (P&lt;0.01, for all parameters). According to multivariate analysis models, CAR (HR: 1.020, P&lt;0.01) and TVAR score (HR: 1.294, P&lt;0.01) were found to be independent predictors of early mortality while CRP and albumin were not. The area under the curve (AUC) for CAR was 0.73 with a P &lt;0.01. A CAR &gt;15.6 predicted the early mortality with 80% sensitivity and 57% specificity. Conclusion: The novel inflammatory marker CAR can be used as a reliable marker in predicting 30-day mortality in patients undergoing TAVR.
