Hepatic steatosis and severity-related factors in obese children.

Background And Aim: Obesity is an important health-care problem in developed countries. It is considered a multisystemic disease, but it may also affect the liver, thus provoking non-alcoholic fatty liver disease. This disease has been less extensively studied among children than among adults.

Complications in immediate breast reconstruction after mastectomy.

Objectives: Immediate post-mastectomy breast reconstruction (IBR) is a procedure that has proven advantages, but it also entails risks. The aim of this study was to identify risk factors for reconstruction failure.

Methods: A review was made of all the IBR carried out at a general hospital from 2002 to 2009.

[Prognostic factors and long-term survival after initial diagnosis of heart failure].

Background And Objective: To assess long-term mortality and prognostic factors after initial diagnosis of heart failure (HF), to analyze the differences in function of the left ventricular ejection fraction (preserved [HFPEF] vs. systolic dysfunction [HFSD]) and to compare the results with the main series of incident cases of HF published.

Patients And Methods: Retrospective cohort study including patients first diagnosed of heart failure (Framingham criteria), between 1-01-1997 and 31-12-2001, classified according to a left ventricle ejection fraction (LVEF) above or equal to 50% (HFPEF) or below 50% (HFSD).

Development and validation of clinical scores for visual outcomes after cataract surgery.

Purpose: To develop and validate a clinical score to predict visual acuity (VA) and functional changes after phacoemulsification on the basis of readily obtainable preoperative history data and patient assessment.

Design: Prospective follow-up study.

Participants: A sample of 5512 patients on waiting lists for phacoemulsification at 17 hospitals in Spain.
