Renal cell carcinoma and visceral adipose index: a new risk parameter

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Purpose: The aim of this study was to evaluate the relationship between tumor size and grade with visceral adipose index (VAI) levels in patients with renal cell carcinoma. Materials and methods: We retrospectively reviewed the records of 310 consecutive patients with RCC who underwent radical...

External validation of EORTC risk scores to predict recurrence after transurethral resection of brazilian patients with non-muscle invasive bladder cancer stages Ta and T1

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Validate the EORTC risk tables in Brazilian patients with NMIBC. Methods: 205 patients were analyzed. The 6 parameters analyzed were: histologic grading, pathologic stage, size and number of tumors, previous recurrence rate and concomitant CIS. The time for first recurrence (TFR), risk score an...

Paraoxonase 1 (PON1) Q192R genotypes and their interaction with smoking strongly increase atherogenicity and the Framingham risk score

ABSTRACT Objective Paraoxonase 1 (PON1) polymorphisms are associated with an increased susceptibility to cardiovascular disease. PON1 Q192R polymorphism (rs662) partially determine PON1 hydrolytic activity and protect against oxidation of LDL and HDL. This study aimed to delineate the association of PO...

Hypocalcemia development in patients operated for primary hyperparathyroidism: Can it be predicted preoperatively?

ABSTRACT Objective Primary hyperparathyroidism (PHP) is a common endocrine disease, and its most effective treatment is surgery. Postoperative hypocalcemia is a morbidity of parathyroid surgeries, and it may extend hospitalization durations. The purpose of this study is to determine the predictive fact...

Fragmented QRS for Risk Stratification in Patients Undergoing First Diagnostic Coronary Angiography

Arq. bras. cardiol; 107 (4), 2016
Abstract Background: Only a small proportion of patients referred for coronary angiography with suspected coronary artery disease (CAD) have the diagnosis of obstructive CAD confirmed by the exam. For this reason, further strategies for risk stratification are necessary. Objective: To investigate the r...

A simple scoring system for predicting early major complications in spine surgery: the cumulative effect of age and size of surgery

Arq. neuropsiquiatr; 74 (10), 2016
ABSTRACT Objective To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. Methods Retrospective analysis of 583 surgically-treated patients. Early “major” complications were defined as those that may lead to permanent det...

Relationship between Calcium Score and Myocardial Scintigraphy in the Diagnosis of Coronary Disease

Arq. bras. cardiol; 107 (4), 2016
Abstract Half the patients with coronary artery disease present with sudden death - or acute infarction as first symptom, making early diagnosis pivotal. Myocardial perfusion scintigraphy is frequently used in the assessment of these patients, but it does not detect the disease without flow restriction, ...

Longitudinal assessment of nutritional risk in patients under chemo or radiotherapy

Summary Objective: To compare nutritional risk in adult patients undergoing chemotherapy and radiotherapy in the beginning, middle, and end of oncologic treatment. Method: This prospective, comparative study included 83 adult patients, 44 undergoing chemotherapy (CT group) and 39 undergoing radiotherap...

Application of prognostic score IPSET-thrombosis in patients with essential thrombocythemia of a Brazilian public service

Summary Introduction: In patients with essential thrombocythemia (ET), the vascular complications contribute to morbidity and mortality. To better predict the occurrence of thrombotic events, an International Prognostic Score for Thrombosis in Essential Thrombocythemia (IPSET-thrombosis) has recently be...

Syntax Score and Major Adverse Cardiac Events in Patients with Suspected Coronary Artery Disease: Results from a Cohort Study in a University-Affiliated Hospital in Southern Brazil

Arq. bras. cardiol; 107 (3), 2016
Abstract Background: The importance of coronary anatomy in predicting cardiovascular events is well known. The use of traditional anatomical scores in routine angiography, however, has not been incorporated to clinical practice. SYNTAX score (SXscore) is a scoring system that estimates the anatomical ex...
