Total hip arthroplasty can be associated with substantial blood loss requiring allogenic transfusions. Intraoperative blood loss patterns in DAA differ from other approaches. This study evaluated the hemostatic efficacy of a bipolar sealer in DAA THA on surgical blood loss and transfusion requirements. 118 patients were enrolled in this prospective, randomized, double-blinded trial. Primary outcome measure was transfusion rate, while secondary measures included calculated blood loss. A lower transfusion rate was found in the treatment group (3.5 % vs 16.4%, P=.03). There were differences in Hemoglobin-drop (P=.04), calculated blood loss (P=.02), and hidden blood loss (P=.02), favoring the treatment group. The use of a bipolar sealer decreased intraoperative blood loss and transfusion requirements in the study population. © 2015.

Acetabular component malposition contributes to increased complications and early revision. Supine positioning during direct anterior approach (DAA) THA facilitates the use of fluoroscopy to improve component positioning. This study evaluated the accuracy of acetabular component orientation using intraoperative fluoroscopy in DAA THA. A total of 780 surgeries by two surgeons were retrospectively reviewed over a 3-year period. Ranges for abduction (30°-50°) and version (5°-250) were employed. Overall, 92% fell within the targeted abduction range, 93% fell within the targeted anteversion range, and 88% met both criteria. The accuracy of component positioning for combined abduction and anteversion improved yearly (79.2%, 2011; 90.9%, 2012; and 95.6%, 2013). Fluoroscopy in DAA THA is a useful tool to improve acetabular component orientation, though a learning curve exists with its interpretation. © 2015 Elsevier Inc..

This study compared results from plating urine specimens with the BD InoqulA instrument using a 10-μl inoculum with results from cultures plated manually with a 1-μl loop for comparable 2-month periods. The positivity rates, turnaround times for positive cultures, and BD Phoenix identification and antimicrobial susceptibility test results were comparable for both time periods. We experienced no problems with culture interpretation as the result of moving to the 10-μl inoculum. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

Background: The performance of comorbidity measures for predicting mortality in chronic disease populations and using ICD-9 diagnosis codes in administrative health data has been investigated in several studies, but less is known about predictive performance with ICD-10 data and for other health outcomes. This study investigated predictive performance of five comorbidity measures for population-based diabetes cohorts in administrative data. The objectives were to evaluate performance for: (a) disease-specific and general health outcomes, (b) data based on the ICD-9 and ICD-10 diagnoses, and (c) different age groups. Methods. Performance was investigated for heart attack, stroke, amputation, renal disease, hospitalization, and death in all-age and age-specific cohorts. Hospital records, physician billing claims, and prescription drug records from one Canadian province were used to identify diabetes cohorts and measure comorbidity. The data were analysed using multiple logistic regression models and summarized using measures of discrimination, accuracy, and fit. Results: In Cohort 1 (n = 29,058), for which only ICD-9 diagnoses were recorded in administrative data, the Elixhauser index showed good or excellent prediction for amputation, renal disease, and death and performed better than the Charlson index. Number of diagnoses was a good predictor of hospitalization. Similar results were obtained for Cohort 2 (n = 41,925), in which both ICD-9 and ICD-10 diagnoses were recorded in administrative data, although predictive performance was sometimes higher. For age-specific models of mortality, the Elixhauser index resulted in the largest improvement in predictive performance in all but the youngest age group. Conclusions: Cohort age and the health outcome under investigation, but not the diagnosis coding system, may influence the predictive performance of comorbidity measure for studies about diabetes populations using administrative health data. © 2013 Lix et al.; licensee BioMed Central Ltd.

Purpose To report procedural and patient outcomes of endovascular treatment for lower-extremity deep vein thrombosis (DVT) with rheolytic thrombectomy (RT). Materials and Methods A total of 32 sites in the United States and Europe enrolled patients with DVT in the Peripheral Use of AngioJet Rheolytic Thrombectomy with a Variety of Catheter Lengths (PEARL) registry. Patient characteristics and outcomes data were collected from consenting patients who underwent rheolytic AngioJet thrombectomy at investigative sites from January 2007 through June 2013. Three hundred twenty-nine patients were enrolled, with 67% of patients undergoing an AngioJet procedure within 14 days of the onset of symptoms. Results Four treatment approaches using AngioJet thrombectomy were identified: RT without lytic agent in 4% of patients (13 of 329), pharmacomechanical catheter-directed thrombolysis (PCDT) in 35% (115 of 329), PCDT and catheter-directed thrombolysis (CDT) in 52% (172 of 329), and RT in combination with CDT in 9% (29 of 329). Median procedure times for RT alone, PCDT, PCDT/CDT, and RT/CDT were 1.4, 2, 22, and 41 hours, respectively (P <.05, Kruskal-Wallis test). Procedures were completed in less than 24 hours for 73% of patients, with 36% of procedures completed within 6 hours; 86% of procedures required no more than 2 catheter laboratory sessions. The 3-, 6-, and 12-month freedom from rethrombosis rates were 94%, 87%, and 83%, respectively. Major bleeding events occurred in 12 patients (3.6%), but none were related to the AngioJet procedure. Conclusions PEARL registry data demonstrate that rheolytic PCDT treatment of DVT is safe and effective, and can potentially reduce the need for concomitant CDT and intensive care. © 2015 SIR.
