Meta-Analytic Use of Balanced Identity Theory to Validate the Implicit Association Test.

This meta-analysis evaluated theoretical predictions from balanced identity theory (BIT) and evaluated the validity of zero points of Implicit Association Test (IAT) and self-report measures used to test these predictions. Twenty-one researchers contributed individual subject data from 36 experiments (total = 12,773) that used both explicit and implicit measures of the social-cognitive constructs. The meta-analysis confirmed predictions of BIT's balance-congruity principle and simultaneously validated interpretation of the IAT's zero point as indicating absence of preference between two attitude objects.

Altered neurometabolites and motor integration in children exposed to methamphetamine in utero.

Methamphetamine (METH) is a neurotoxic drug. This study aimed to evaluate brain metabolite levels and cognitive function in young children with prenatal METH exposure. 101 children ages 3-4 years were evaluated with neuropsychological tests and underwent proton magnetic resonance spectroscopy ((1)H-MRS) without sedation.

Tumour volume is an independent predictor of prostate-specific antigen recurrence in patients undergoing radical prostatectomy for clinically localized prostate cancer.

Unlabelled: Authors from the USA sought to establish the relationship between tumour volume, pathological stage and outcomes after radical prostatectomy. In a large series of patients they found that tumour volume was correlated directly with pathological stage, and that it was independently correlated with PSA recurrence. The authors suggested that tumour volume had a potential use for prognostication in patients undergoing radical prostatectomy.

Intraoperative blood loss and transfusion requirements for robotic-assisted radical prostatectomy versus radical retropubic prostatectomy.

Objectives: To compare intraoperative blood loss, perioperative hematocrit, and transfusion requirements in patients undergoing radical retropubic prostatectomy (RRP) versus robotic-assisted laparoscopic prostatectomy (RALP) by a single surgeon.

Methods: During a 14-month period, 279 patients with localized carcinoma of the prostate were prospectively enrolled in this comparative study. The decision of which surgical approach to use was by patient choice.
