Surgical aortic valve replacement in octogenarians: Single-center perioperative outcomes and five-year survival.

Introduction And Objectives: Aortic stenosis is the most common valvular heart disease. The number of octogenarians proposed for intervention is growing due to increased lifespan. In this manuscript we aim to evaluate perioperative outcome and long-term survival after surgical aortic valve replacement (SAVR) in octogenarians, comparing patients with low surgical risk (EuroscoreII <4%) with intermediate-high risk (EuroscoreII ≥4%).

Association between frailty phenotype, quantification of plasma HIV-1 RNA, CD4 cell count and HAART in HIV-positive subjects: a systematic review and meta-analysis of observational studies.

HIV infection causes a constant activation of the immune system and contributes to an enhanced systemic pro-inflammatory cytokine milieu, which has been associated with premature aging and frailty. We performed a systematic review and meta-analysis to analyze whether the HIV-1 RNA load, CD4+ T-lymphocyte counts and exposure to HAART in HIV-positive subjects are associated with frailty phenotype. Searches were performed in PubMed, SCOPUS, Lilacs, Web of Science, Google Scholar, and OpenThesis databases.

Oral and maxillofacial conditions, dietary aspects, and nutritional status of children with congenital Zika syndrome.

Objective: The aim of this study was to investigate oral and maxillofacial outcomes in children with congenital Zika syndrome (CZS) and the presence of nonnutritive sucking habits, functional habits, and features related to breastfeeding and nutrition of these children.

Study Design: We conducted a cross-sectional study with 45 children with CZS and 50 healthy controls in Sergipe state, Brazil, from February 2018 to June 2018. Demographic and clinical data, including breastfeeding and feeding data, were obtained for each child.

Femicide trends in Brazil: relationship between public interest and mortality rates.

In this information epidemiology (infodemiology) study, we describe the online public interest about the issue of femicide in Brazil and analyze the relationship between search queries and femicide trends from 2004 to 2015. We showed that information-seeking behavior for femicide in the Brazilian states has been strongly influenced by female homicide rates. Educational and policy-related interventions are needed to improve the population's knowledge and attitude toward femicide.

[Results of the utilization of the ECMO-VA following cardiac surgery, in the Department of Cardiothoracic Surgery of Santa Maria Hospital].

Objectives: Extracorporeal membrane oxygenation through a veno-arterial circuit (ECMO-VA) is an organ support option in refractory cardiogenic shock, when the primary cause of decompensation is thought to be reversible. We report the clinical results of this technique in patients submitted to cardiac surgery at our center.

Methods: We present a retrospective study of patients that underwent ECMO-VA after cardiac surgery and subsequent admission at the intensive care unit (ICU), in our center.

[Perioperative myocardial infarction in coronary bypass surgery: characterization of risk factors, clinical pictures and prognosis].

Unlabelled: Perioperative myocardial infarction ( POMI ) in cardiac surgery is an issue that deserves to be revisited.

Objective: To evaluate the risk factors, clinical characteristics and prognosis of POMI in high-risk patients ( pts ) undergoing coronary bypass surgery ( CABG ).

Material And Methods: Retrospective study of 694 pts undergoing isolated CABG - 252 pts with conventional CABG and 442 pts with off-pump CABG - and operated on by 4 surgeons largely experienced in both CABG modalities.

Impact of intraoperative transesophageal echocardiography in cardiac surgery: retrospective analysis of a series of 850 examinations.

Objective: To evaluate the impact of intraoperative transesophageal echocardiography (TEE) on surgical decisions patients undergoing cardiac surger in a Portuguese hospital.

Methods: The authors retrospectively analyzed a series of 850 examinations performed between 2003 and 2009 in patients who underwent different cardiac surgical procedures. Medical records and TEE reports were reviewed to determine whether new information was found and whether this changed the surgical plan.

[Advantages of off-pump coronary bypass surgery over conventional coronary bypass surgery].

Unlabelled: Comparison between off-pump coronary bypass surgery ( OP-CABG )and conventional CABG ( C-CABG ) remains a controversial issue.

Objective: To compare short and long term OP-CABG and C-CABG results in high-risk patients ( pts ), in absence of usual bias.

Material And Methods: A prospective observational study of 752 pts ( 252 pts with C-CABG and 500 with OP-CABG ) consecutively operated throughout 23 months by 4 surgeons largely experienced in both CABG modalities.

Fragmentation channels in dissociative electron recombination with hydronium and other astrophysically important species.

We report on our recent studies of dissociative recombination (DR) employing two different fragment imaging detection techniques at the TSR storage ring in Heidelberg, Germany. Principles of an upgraded 3D optical system and the new energy-sensitive multistrip detector (EMU) are explained together with possible applications in reaction dynamics studies. With the EMU imaging detector we succeeded to observe the branching ratios after DR of deuterated hydronium ions D(3)O(+) at energies of 0-0.

[Results of Dor's endoventricular repair in the management of left ventricular aneurysms].

Introduction: Left ventricular aneurysms are serious long-term complications from acute myocardial infarction that produce hemodynamic alterations in the cardiac function.

Objective: The aim of this study is to evaluate the chirurgical and clinic results of the endoventricular patch repair of the akinetic or dyskinetic portions of the left ventricle.

Methods: From August 2002 to October 2005, 20 consecutive patients underwent surgical repair of left ventricular aneurysm using the endoventricular patch repair technique.

[Grawitz tumor with invasion of the inferior vena cava and right atrium: surgical management with a multidisciplinary team].

In this paper, the clinical condition of a 56 year old male patient is reported, with the diagnosis of renal cell carcinoma, complicated by a tumoral thrombus, extended from the renal vein into the vena cava and right atrium, who underwent surgical treatment. The operation consisted in the radical nephrectomy associated to the vena caval thrombectomy, under extracorporeal circulation, utilizing a multidisciplinary team composed by urologists, vascular and cardio-thoracic surgeons. The main features related to the diagnosis and surgical management of this case are described and discussed, according to data taken from the most recent publications of the literature on the subject.

[Reoperation in mitral valve reconstructive surgery].

Unlabelled: In the past few years reconstructive surgery of the mitral valve has experienced a growing popularity. It is now clearly established that restoration of a normal function valve is preferable to valve replacement. The authors report the results of the mitral valve reconstructive surgery in a population of 701 patients with high incidence of restrictive lesions of rheumatic fever.
