1. Proadrenomedullin in Patients with Preserved Left Ventricular Systolic Function Undergoing Coronary Artery Bypass Grafting
Abstract Introduction: A potentially new marker of cardiovascular diseases — proadrenomedullin is the precursor of adrenomedullin, which is a multifunctional peptide hormone, produced in most of the tissues in response to cellular stress, ischemia, and hypoxia. Methods: Ninety-three people, aged 51-79 years, were included in the study. Exclusion criteria

2. Urorectal fistula repair using different approaches: operative results and quality of life issues
ABSTRACT Purpose: To evaluate efficacy of urorectal fistula (URF) repair using different approaches and the clinical factor determinant of success, and also the morbidity associated to the procedure and health-related quality of life (HRQoL) in male survivors of pelvic malignancies. Material and Methods: Retrospective evaluation of 39 patients with URF pri

3. Predictors of Post-Discharge 30-Day Hospital Readmission in Decompensated Heart Failure Patients
Abstract Background Heart failure (HF) is worldwide known as a public health issue with high morbimortality. One of the issues related to the evolution of HF is the high rate of hospital readmission caused by decompensation of the clinical condition, with high costs and worsening of ventricular function. Objective To quantify the readmission rate and ide

4. Assessment of long term outcomes after buccal mucosal graft urethroplasty: the impact of chronic kidney disease
ABSTRACT Objectives To compare and assess various outcomes and success of buccal mucosal graft urethroplasty (BMGU) in patients with CKD versus patients having normal renal function. Material and Methods This was a retrospective, single centre study, during period 2013 to 2017. Patients were grouped into two groups. Group 1 had patients with estimated Gl

5. Risk of Obstructive Sleep Apnea and Echocardiographic Parameters
Resumo Fundamento: A apneia obstrutiva do sono (AOS) é um transtorno crônico, progressivo, com alta morbimortalidade e associado às doenças cardiovasculares (DCV), entre elas a insuficiência cardíaca (IC). As alterações fisiopatológicas relacionadas com a AOS podem impactar diretamente a função diastólica do ventrículo esquerdo. Objetivo: Esti

6. Efficacy, Safety, and Performance of Isolated Left vs. Right Ventricular Pacing in Patients with Bradyarrhythmias: A Randomized Controlled Trial
Resumo Fundamento: Considerando-se os potenciais efeitos deletérios da estimulação do ventrículo direito (VD), a hipótese desse estudo é que a estimulação unifocal ventricular esquerda pelo seio coronário é segura e pode proporcionar melhores benefícios clínicos e ecocardiográficos aos pacientes com bradiarritmias que apresentam função ventr

7. A new class of lifetime models and the evaluation of the confidence intervals by double percentile bootstrap
Abstract: In this paper, we introduce a new three-parameter distribution by compounding the Nadarajah-Haghighi and geometric distributions, which can be interpreted as a truncated Marshall-Olkin extended Weibull. The compounding procedure is based on the work by Marshall and Olkin 1997. We prove that the new distribution can be obtained as a compound model w

8. A practical approach to assess leg muscle oxygenation during ramp-incremental cycle ergometry in heart failure
Heart failure is characterized by the inability of the cardiovascular system to maintain oxygen (O2) delivery (i.e., muscle blood flow in non-hypoxemic patients) to meet O2 demands. The resulting increase in fractional O2 extraction can be non-invasively tracked by deoxygenated hemoglobin concentration (deoxi-Hb) as measured by near-infrared spectroscopy (NI

9. Abnormal diastolic function underlies the different beneficial effects of cardiac resynchronization therapy on ischemic and non-ischemic cardiomyopathy
OBJECTIVES: To investigate the association between diastolic function and the different beneficial effects of cardiac resynchronization therapy in patients with heart failure due to different causes. METHODS: The 104 enrolled patients were divided into an ischemic cardiomyopathy group (n=27) and a non-ischemic cardiomyopathy group (n=77) according to the c

10. Association between MFN2 gene polymorphisms and the risk and prognosis of acute liver failure: a case-control study in a Chinese population
This study aimed to determine the role of mitofusin 2 (MFN2) gene polymorphisms in the risk and prognosis of acute liver failure (ALF). A total of 298 blood samples were collected from 138 ALF patients (case group) and 160 healthy participants (control group). Coagulation function, glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT),

11. THE COMPOSED ZERO TRUNCATED LINDLEY-POISSON DISTRIBUTION
ABSTRACT In this paper, a new compounding distribution, named zero truncated Lindley-Poisson distribution is introduced. The probability density function, cumulative distribution function, survival function, failure rate function and quantiles expressions of it are provided. The parameters estimatives were obtained by six methods: maximum likelihood (MLE), o

12. Damage evolution in a tensile specimen of a ductile stainless steel
Abstract This paper presents a study about the fracture mechanism of a ferritic stainless steel (UNS S44400 type) during a tensile test. The applied materials for the experimental procedures were 25 specimens of the steel, machined in the rolling direction. Each specimen was submitted to standard polishing procedures. One of the samples, in the original stat
