Autogenous arteriovenous fistula creation is the preferred route for vascular access for hemodialysis. Although preoperative venous mapping ultrasonography has been advocated as an operative planning adjunct and recently incorporated into the Society for Vascular Surgery clinical guidelines, controversy remains regarding its usefulness for predicting access success. The purpose of the present retrospective clinical study was to test the hypothesis that vein size measured on routine preoperative venous mapping is a poor predictor of primary fistula maturation.

Consecutive upper extremity autogenous arteriovenous fistulas created by three dedicated vascular surgeons were retrospectively reviewed. The demographic characteristics, preoperative venous mapping, functional maturation, and patency were analyzed. The clinically relevant variables were tested for predictive significance using a logistic regression model.

A total of 199 upper extremity autogenous arteriovenous fistulas had been created during a 5-ng does not predict successful primary maturation. Also, no clinically useful predictor of fistula maturation was identified in the present study.

We investigated the outcomes of endovascular repair for penetrating aortic ulcers (PAUs) with and without intramural hematoma (IMH).

Patients with PAUs who had undergone thoracic endovascular aortic repair (TEVAR) or endovascular abdominal aortic repair (EVAR) at our center were enrolled. Patient demographics, presenting symptoms, and anatomic characteristics were collected and analyzed to investigate the TEVAR/EVAR indications, perioperative complications, and mortality.

We identified 138 patients with PAU. Of the 138 patients, 58 (42.0%) had also had IMH. learn more Compared with the patients without IMH, the patients with IMH had had significantly greater emergency admission rates (P< .01), a larger aortic diameter (P= .03), and a greater incidence of stent-induced new entry development (P= .02). No significant differences were found in mortality or freedom from reintervention between patients with PAUs with and without IMH during follow-up. However, the cumulative survival rates calculated using Kaplan-Meier analysis for patients who had undergone TEVAR/EVAR during their first hospitalization were significantly greater than those who had undergone delayed TEVAR/EVAR during follow-up.

TEVAR/EVAR was safe and effective, with encouraging outcomes for patients with PAUs with or without IMH, and can be used more aggressively for symptomatic patients. The presence of PAUs with IMH did not seem to adversely affect long-term mortality. However, but stent-induced new entry was more likely to develop.

Our aim was to create a process to recapture, reprocess, and redistribute N95 masks using hydrogen peroxide vapor as a real time disinfection method within a large hospital system. We were able to recapture and reprocess 29, 706 N95 masks using hydrogen peroxide vapor with approximately 25% loss due to damage.

Surgical site infections (SSIs) are a serious and costly post-op complication. Generating SSI rates often requires labor-intensive methods, but increasing numbers of publications reported SSI rates using administrative data.

Index laminectomy and spinal fusion procedures were identified using Canadian Classification of Health Interventions (CCI) procedure codes for inpatients and outpatients in the province of Alberta, Canada between 2008 and 2015. SSIs occurring in the year postsurgery were identified using the International Classification of Diseases, 10th Revision, Canada (ICD-10-CA) diagnosis and CCI procedure codes indicative of post-op infection. Rates of SSIs and case characteristics were reported.

Over the 8-year study period, 21,222 index spinal procedures were identified of which 12,027 (56.7%) were laminectomy procedures, with 322 SSIs identified, an SSI rate of 2.7 per 100 procedures. Of the 9,195 (43.3%) fusion procedures, 298 were identified as an SSI, an SSI rate of 3.2 per 100 procedures. This study found SSI rates increased from 2008 and 2015, and rates were the highest in the 0-18 year age group.

The rates reported in this study were similar to published SSI rates using traditional surveillance methods, suggesting administrative data may be a viable method for reporting SSI rates following spinal procedures. Further work is needed to validate SSIs identified using administrative data by comparing to traditional surveillance.

Medical gowns are essential personal protective equipment (PPE) that prevents the spread of microorganisms and bodily fluids. During surge capacity situations, such as the COVID-19 pandemic, reusable PPE is often recommended due to shortages.

This research evaluated the performance of disposable versus reusable medical gowns by assessing their ability to provide adequate protection across their expected service lifespan. Level I, II, and III gowns were tested for water resistance and hydrostatic pressure, along with other durability assessments (breaking, tear, and seam strength, pilling resistance, dimensional stability, and air permeability, colorfastness, and fabric hand) per standard test methods. Data were collected at new for the disposable gowns and after 1, 25, 50, and 75 industrial launderings for the reusable gowns. Results were compared to the Association of the Advancement Instrumentation® (AAMI) PB70 performance specifications.

Level I and II disposable gowns did not meet AAMI performance specifications for impact penetration water resistance.
