PRECISE Scale: a quantitative classification for androgenetic alopecia and its application to hair transplantation.

Background: Androgenetic alopecia (AGA) is a prevalent genetic condition that can affect both male and female, and is considered the most frequent form of hair loss. Traditional scales and methods of classifying AGA are basically qualitative.

Objective: This work aims to propose a quantitative scale to classify AGA in order to assist hair transplantation surgery.

Mortality and morbidity of patients on the waiting list for coronary artery bypass graft surgery.

Objectives: The public health care system in Brazil has extensive waiting lists of patients requiring complex operations such as coronary artery bypass grafting (CABG). The purpose of this study was to identify the mortality and morbidity rates of the patients awaiting CABG and identify predictors of adverse events and their association with perioperative outcomes.

Methods: We conducted a retrospective analysis of outpatient medical records of patients referred for this elective procedure in Rio de Janeiro, Brazil.

Age influences outcomes in 70-year or older patients undergoing isolated coronary artery bypass graft surgery.

Objective: To analyze the results of isolated on-pump coronary artery bypass graft surgery (CABG) in patients >70 years-old in comparison to patients <70 years-old.

Methods: Patients undergoing isolated CABG were selected for the study. The patients were grouped in G1 (age > 70 years-old) and G2 (age <70 years-old).

Increased preoperative C-reactive protein levels are associated with inhospital death after coronary artery bypass surgery.

Increased C-reactive protein (CRP) is a predictor of cardiovascular risk, but its influence on outcomes after coronary artery bypass grafting surgery (CABG) is still incompletely studied. We studied the association between preoperative CRP and inhospital death after CABG. Patients with acute or chronic infectious or inflammatory disorders, autoimmune diseases, cancer, and prior cardiac surgery were excluded.

Outcomes of patients with left main coronary artery disease undergoing medical or surgical treatment: a propensity-matched analysis.

Objective: To evaluate the outcomes of patients with significant (≥ 50%) left main coronary artery disease (LMCAD) undergoing medical treatment (MT) or coronary artery bypass grafting surgery (CABG).

Methods: A total of 181 patients with significant LMCAD were followed for 4 ± 2 years. MT was done when patients refused CABG or because of either thin native vessels or high clinical risk.

Functional assessment of coronary grafts on dobutamine pharmacological stress echocardiogram.

Objective: To verify the sensitivity, specificity and diagnostic accuracy of dobutamine stress echocardiogram (DSE) when assessing the functional status of coronary grafts: sufficient (SUF) or insufficient (INS).

Methods: We carried out a prospective, observational study which included 25 patients submitted to coronary artery bypass grafting (CABG). The DSE and the coronary angiography were performed before the CABG and three months after the CABG.

High mortality associated with precluded coronary artery bypass surgery caused by severe distal coronary artery disease.

Background: Patients with extensive coronary artery disease (CAD) have better prognosis when treated with coronary artery bypass grafting surgery (CABG), especially when left ventricular dysfunction (LVD) is present. However, there are scanty data about the clinical course of patients not referred to CABG because of extensive and severe atherosclerotic involvement of distal coronary arteries (ENDCAD). The aim of this study was to evaluate patients with multivessel (MV) or left main CAD (LM) who had CABG precluded because of ENDCAD.
