There have been few studies to date that investigate the effect of race on outcomes related to coronary artery bypass grafting. The objective of the present study was to investigate race as an independent predictor of outcomes among patients undergoing coronary artery bypass graft (CABG). A nested case-control study from a twelve-year hospitalization cohort (N=9671) in which data were collected prospectively was conducted. ⋯ Multivariate analysis revealed African-Americans were at greater risk for renal complications (OR 1.88, 95% CI 1.27-2.77), neurological complications (OR 1.34, 95% CI 1.01-1.77), and pulmonary complications (OR 2.11, 95% CI 1.72-2.59). African Americans had a significantly longer hospitalization post-operatively (OR 0.79, 95% CI 0.66-0.96), but were less likely to experience post-operative atrial fibrillation requiring treatment than Caucasians (OR 0.64, 95% CI 0.49-0.84). Even after multiple adjustments, African-Americans undergoing CABG surgery had significantly greater morbidity compared to Caucasian patients.

Combined use of gas chromatography and selected ion flow tube mass spectrometry for absolute trace gas quantification.
The value of the gas chromatography (GC) and selected ion flow tube mass spectrometry (SIFT-MS) combination for the analysis of trace gases is demonstrated by the quantification of acetone in air samples using the three precursor ions available to SIFT-MS, viz. H3O+, NO+ and O2+, and by the separation of the isomers 1-propanol and 2-propanol, and their analysis using H3O+ precursor ions. It is shown that the GC/SIFT-MS combination allows for accurate trace gas quantification obviating the regular, time-consuming calibrations that are usually required for the more commonly used detectors of GC systems, and the positive identification of isomers in mixtures that is often challenging using SIFT-MS alone. Thus, the GC/SIFT-MS combination paves the way to more confident analyses of complex mixtures such as exhaled breath.

There are numerous methods of treatment for pilonidal abscess; however the best method in acute pilonidal abscess has remained controversial. The present study was designed to compare drainage, delayed excision and primary closure with excision and secondary healing in this relation. ⋯ The results of drainage and primary wound closure were comparable to the excision and secondary wound healing except in the rate of recurrence which was more frequent in the primary wound closure. As a result, in spite of much property and comfort of primary wound closure, this method would not be recommended for all cases with acute pilonidal abscess.

Hypnosis Antenatal Training for Childbirth (HATCh): a randomised controlled trial [NCT00282204].
Although medical interventions play an important role in preserving lives and maternal comfort they have become increasingly routine in normal childbirth. This may increase the risk of associated complications and a less satisfactory birth experience. Antenatal hypnosis is associated with a reduced need for pharmacological interventions during childbirth. This trial seeks to determine the efficacy or otherwise of antenatal group hypnosis preparation for childbirth in late pregnancy. ⋯ If effective, hypnosis would be a simple, inexpensive way to improve the childbirth experience, reduce complications associated with pharmacological interventions, yield cost savings in maternity care, and this trial will provide evidence to guide clinical practice.

Celecoxib reduces narcotic use and pain following augmentation mammaplasty.
Narcotics have traditionally been used to control pain after augmentation mammaplasty, but they have adverse side effects, including addiction potential, clouded sensorium, nausea, and respiratory depression. Alternative strategies for managing postoperative pain are expensive, cumbersome, and also have their own risks. While long-term use of celecoxib has been associated with an increased risk of serious adverse cardiovascular effects, no problems have been reported with short-term use. ⋯ Perioperative celecoxib administration in patients undergoing augmentation mammaplasty significantly reduced postoperative narcotic use, pain, and nausea. Its use should facilitate the patient's ability to resume everyday activities following surgery.
