When innovation meets patient blood management - a new way to see bleeding.

The first step in innovation is to identify a problem of real relevance and systematically address it to deliver a sophisticated and viable solution. Disruptive innovation is a process where technology, products, or services are transformed or replaced by a better innovative solution. This superiority must be perceived by users as being more accessible, simple, or convenient.

Applicability of the Disruptions in Surgery Index in the Cardiovascular Management Scenarios - A Marker for Developing Functionally Efficient Teams.

Introduction: To support the development of practices and guidelines that might help to reduce adverse events related to human factors, we aimed to study the response and perception by members of a cardiovascular surgery team of various error-driven or adverse features that might arise in the operating room (OR).

Methods: A previously validated Disruptions in Surgery Index (DiSI) questionnaire was completed by individuals working together in a cardiovascular surgical unit. Results were submitted to reliability analysis by calculating the Cronbach's alpha coefficient.

It was established with one wet lab session weekly lasting 2 h, coached by two expert cardiovascular surgeons.

Omeprazole and adenocarcinoma in the stomach of rats submitted to duodenogastric reflux. Is there a protective effect?

Purpose: To investigate the role of omeprazole and nitrites on the gastric mucosa of rats submitted to specific techniques to induce duodenogastric reflux.

Methods: One hundred and twenty Wistar rats were divided into three groups: Group I (n=40) -gastrotomy; Group II (n=40) - duodenogastric reflux after gastrojejunoanastomosis latero-lateral (DGR); Group III (n=40) - retrograde duodenogastric reflux through the pylorus (DGR-P). The groups were divided into 4 subgroups of 10 animals, respectively treated for 16 weeks with water, omeprazole 1.

Neurologic manifestations in emerging arboviral diseases in Rio de Janeiro City, Brazil, 2015-2016.

Introduction: Dengue has affected Rio de Janeiro City since the 1980s. The sequential Zika and chikungunya virus introductions during 2015 aggravated the health scenario, with 97,241 cases of arboviral diseases reported in 2015-2016, some with neurological disorders.

Methods: Arbovirus-related neurologic cases were descriptively analyzed, including neurological syndromes and laboratory results.

Left ventricular chamber geometry in cardiomyopathies: insights from a computerized anatomical study.

Aims: Some authors have hypothesized that left ventricular chamber dilatation in ischaemic and idiopathic cardiomyopathies results in spherical transformation. Aiming to characterize how this transformation occurs, a study was performed by comparing normal and dilated specimens regarding sphericity and proportionality in left heart chambers. It is important to provide data for the development of therapeutic strategies in these diseases.

Pre-validation Study of the Brazilian Version of the Disruptions in Surgery Index (DiSI) as a Safety Tool in Cardiothoracic Surgery.

Introduction: Most risk stratification scores used in surgery do not include external and non-technical factors as predictors of morbidity and mortality.

Objective: The present study aimed to translate and adapt transculturally the Brazilian version of the Disruptions in Surgery Index (DiSI) questionnaire, which was developed to capture the self-perception of each member of the surgical team regarding the disruptions that may contribute to error and obstruction of safe surgical flow.

Methods: A universalist approach was adopted to evaluate the conceptual equivalence of items and semantics, which included the following stages: (1) translation of the questionnaire into Portuguese; (2) back translation into English; (3) panel of experts to draft the preliminary version; and (4) pre-test for evaluation of verbal comprehension by the target population of 43 professionals working in cardiothoracic surgery.

Off-pump versus On-pump Coronary Artery Bypass Grafting in Frail Patients: Study Protocol for the FRAGILE Multicenter Randomized Controlled Trial.

Introduction: Advances in modern medicine have led to people living longer and healthier lives. Frailty is an emerging concept in medicine yet to be explored as a risk factor in cardiac surgery. When it comes to CABG surgery, randomized controlled clinical trials have primarily focused on low-risk (ROOBY, CORONARY), elevated-risk (GOPCABE) or high-risk patients (BBS), but not on frail patients.

General thoracic surgery workforce: training, migration and practice profile in Brazil.

Objectives: This study is aimed at drawing the profile of the Brazilian general thoracic surgeon. This experience has been fruitful in other areas, helping attract manpower and to better serve the interests of other Societies. This is the first survey of this kind in Brazil and in Latin America.

Idiopathic dilated cardiomyopathy: computerized anatomic study of relashionship between septal and free left ventricle wall.

Introduction: A feature of dilated cardiomyopathy is the deformation of ventricular cavity, which contributes to systolic dysfunction. Few studies have evaluated this deformation bearing in mind ventricular regions and segments of the ventricle, which could reveal important details of the remodeling process, supporting a better understanding of its role in functional impairment and the development of new therapeutic strategies.

Objective: To evaluate if, in basal, equatorial and apical regions, increased internal transverse perimeter of left ventricle in idiopathic dilated cardiomyopathy occurs proportionally between the septal and non-septal segment.

Video-assisted thoracoscopy as an option in the surgical treatment of chylothorax after cardiac surgery in children.

Objective: To evaluate the use of video-assisted thoracoscopy in the surgical treatment of chylothorax developed after the surgical correction of congenital heart disease in children.

Methods: We reviewed the medical charts of 3,092 children who underwent surgery for congenital heart disease between February of 2002 and February of 2007 at the Heart Institute of the University of São Paulo School of Medicine Hospital das Clínicas, in São Paulo, Brazil.

Results: Of the 3,092 children, 64 (2.
