Similar 2-point discrimination and stereognosia but better locognosia at long term with an independent home-based sensory reeducation program vs no reeducation after low-median nerve transection and repair.

Study Design: Prospective controlled study.

Introduction: Previous studies evaluated the effectiveness of sensory reeducation (SR) after peripheral nerve injury and repair. However, evidence for long-term clinical usefulness of SR is inconclusive.

Quantitative evaluation of drug or device effects on ventricular remodeling as predictors of therapeutic effects on mortality in patients with heart failure and reduced ejection fraction: a meta-analytic approach.

Objectives: The purpose of this study was to quantitatively assess the relationship between therapy-induced changes in left ventricular (LV) remodeling and longer-term outcomes in patients with left ventricular dysfunction (LVD).

Background: Whether therapy-induced changes in left ventricular ejection fraction (LVEF), end-diastolic volume (EDV), and end-systolic volume (ESV) are predictors of mortality in patients with LVD is not established.

Methods: Searches for randomized controlled trials (RCTs) were conducted to identify drug or device therapies for which an effect on mortality in patients with LVD was studied in at least 1 RCT of > or = 500 patients (mortality trials).

Elevated serum leptin levels: a risk factor for non-small-cell lung cancer?

Objective: Leptin is intimately intertwined in the molecular pathophysiology of several cancer types; with regard to lung cancer, however, limited research has been conducted, with overall conflicting results.

Methods: The present case-control study comprises 66 non-small-cell lung cancer (NSCLC) cases and 132 healthy controls matched for gender and age. Lifestyle, sociodemographic and medical history information has been obtained in addition to body mass index (BMI) measurements and weight change during the last 2 months.

Examination of the steps leading up to the physical developer process for developing fingerprints.

This is a systematic study that examines several acid prewashes and water rinses on paper bearing latent prints before its treatment with a silver physical developer. Specimens or items processed with this method are usually pretreated with an acid wash to neutralize calcium carbonate from the paper before the treatment with a physical developer. Two different acids at varying concentrations were tested on fingerprints.
