Transancestral GWAS of alcohol dependence reveals common genetic underpinnings with psychiatric disorders

Abstract: Liability to alcohol dependence (AD) is heritable, but little is known about its complex polygenic architecture or its genetic relationship with other disorders. To discover loci associated with AD and characterize the relationship between AD and other psychiatric and behavioral outcomes, we carried out the largest genome-wide association study to date of DSM-IV-diagnosed AD. Genome-wide data on 14,904 individuals with AD and 37,944 controls from 28 case-control and family-based studies were meta-analyzed, stratified by genetic ancestry (European, n = 46,568; African, n = 6,280). Independent, genome-wide significant effects of different ADH1B variants were identified in European (rs1229984; P = 9.8 × 10-13) and African ancestries (rs2066702; P = 2.2 × 10-9). Significant genetic correlations were observed with 17 phenotypes, including schizophrenia, attention deficit-hyperactivity disorder, depression, and use of cigarettes and cannabis. The genetic underpinnings of AD only partially overlap with those for alcohol consumption, underscoring the genetic distinction between pathological and nonpathological drinking behaviors.

Repetitive locomotor training and physiotherapy improve walking and basic activities of daily living after stroke: a single-blind, randomized multicentre trial (DEutsche GAngtrainerStudie, DEGAS)

Abstract: Objective: To evaluate the effect of repetitive locomotor training on an electromechanical gait trainer plus physiotherapy in subacute stroke patients.Design: Randomized controlled trial.Setting: Four German neurological rehabilitation centres. Subjects: One hundred and fifty-five non-ambulatory patients (first-time stroke <60 days).Intervention: Group A received 20 min locomotor training and 25 min physiotherapy; group B had 45 min physiotherapy every week day for four weeks.Main outcome measures: Primary variables were gait ability (Functional Ambulation Category, 0-5) and the Barthel Index (0-100), blindly assessed at study onset, end, and six months later for follow-up. Responders to the therapy had to become ambulatory (Functional Ambulation Category 4 or 5) or reach a Barthel Index of ≥ 75. Secondary variables were walking velocity, endurance, mobility and leg power.Results: The intention-to-treat analysis revealed that significantly greater number of patients in group A could walk independently: 41...

Report of the radionuclides in nephrourology committee on renal clearance

Abstract: The need for simple and accurate methods to measure renal function is self-evident. This need increases as techniques for intervention become available. The demand for evaluation of individual kidney function has increased with its role in the diagnosis and follow-up of unilateral renal disease and in decision making for conservative or surgical treatment based on residual renal function. The role of nuclear medicine in this area has been inhibited by confusion about conflicting methodologies. This report is meant to provide guidance to those centers that would like to initiate clearance procedures but have difficulty in choosing appropriate methodology.

Performance of transperineal template-guided mapping biopsy in detecting prostate cancer in the initial and repeat biopsy setting.

Abstract: Transrectal ultrasound (TRUS) biopsy can miss 20–30% of clinically significant cancers. We evaluate an alternative approach—transperineal template-guided mapping biopsy (TTMB) in the initial and repeat biopsy setting. From January 2005 through September 2008, 373 consecutive men underwent TTMB (294 men with ⩾1 prior negative biopsy and 79 men as the initial biopsy). The location of each positive biopsy core, number of positive cores, and percent involvement of each core was recorded. Cancer detection rate for the initial biopsy was 75.9%. For men with 1, 2, and ⩾3 prior negative biopsies detection rates were 55.5%, 41.7%, and 34.4%, respectively. In all, 55.5% of the cancers identified were Gleason ⩾7. The majority of the cancers were multifocal. There was no significant change in the number of positive cores or Gleason score as the number of prior biopsies increased. The anterior and apical aspects of the prostate were among the most common cancer locations. TTMB provides a high rate of cancer detection as initial and repeat biopsy. TTMB was particularly effective at diagnosing anterior and apical cancer. TTMB may have particular application for men considering active surveillance, with prior negative TRUS biopsies, and those considering subtotal gland or other minimally invasive treatments.
