Founded in 1883, the University of Sioux Falls is a Christian liberal arts university located in Sioux Falls, in the U.S. state of South Dakota. USF's mission is to foster academic excellence and the development of mature Christian persons for service to God and humankind in the world. In fall 2014, the University enrolled a total of 1,108 undergraduate students and 311 graduate students. Wikipedia.

Objective: Angioplasty and stenting are options for revascularization of symptomatic femoral popliteal disease. Although angioplasty alone is effective in short lesions, longer lesions are often treated with stents. Multiple overlapping stents are expensive and may be associated with stent fracture. This trial evaluated the safety and efficacy of a single self-expanding stent up to 20 cm in length in patients with atherosclerotic disease of the superficial femoral artery (SFA) and proximal popliteal artery. Methods: Patients with lesions >4 cm and <18 cm were enrolled in this nonrandomized, prospective, multicenter trial that evaluated the Protégé EverFlex Self-Expanding Peripheral Stent System (Covidien, Plymouth, Minn). The study's primary end points were the 30-day major adverse event rate and duplex ultrasound-assessed patency at 1 year. These were compared with published performance goals. A preplanned analysis was conducted for the primary effectiveness end points at 1 year. Follow-up, including history, ankle-brachial index, patient-reported outcomes, duplex ultrasound assessment, and radiographs, is planned through 3 years. There was core laboratory review of angiograms, ultrasound scans, and plain radiographs. A subgroup of patients was studied with graded treadmill testing. Results: The study enrolled 287 patients (66% male; mean age, 68 years) with stenotic, restenotic, or occluded lesions of the SFA at 44 investigational sites in the United States and Europe. Systemic comorbidities included hypertension (88%), hyperlipidemia (86%), diabetes (43%), and prior SFA intervention (41%). The mean lesion length measured by the core laboratory was 89 mm. The mean normal-to-normal lesion length measured by sites was 110 mm. A total of 303 stents were implanted, and 95% of patients received a single stent. No major adverse events occurred at 30 days. At 1 year, primary outcome of duplex ultrasound stent patency was 67.7% in evaluable patients, and among 1-year secondary outcomes, the mean ankle-brachial index increased by 0.25. Walking Improvement Questionnaire scores improved in pain by 33.7, distance by 37.1, speed by 18.6, and stair climbing by 24.7. The Kaplan-Meier estimate of primary patency was 77.2%, primary assisted patency was 86.9%, and secondary patency was 87.3%. Rutherford clinical category improved in 83.5% of patients. Stent fracture rate was 0.4%. Matched absolute claudication distance was 412 feet greater and was not statistically different in this subgroup of 29 individuals. Conclusions: The results of DURABILITY II (StuDy for EvalUating EndovasculaR TreAtments of Lesions in the Superficial Femoral Artery and Proximal Popliteal By usIng the Protégé EverfLex NitInol Stent SYstem II) suggest that a new single stent strategy is safe and effective for the treatment of long lesions of the SFA and proximal popliteal arteries at 1 year. © 2013 by the Society for Vascular Surgery.

Diarrhea is a frequent complication among hospitalized patients. Nosocomial diarrhea is generally diagnosed as increased frequency and decreased consistency of stools developing after 72 hours of hospitalization. The causes of nosocomial diarrhea may be infectious or noninfectious. Noninfectious etiologies occur most commonly, and are often adverse effects of medications or enteral nutrition therapies. Infectious etiologies are most concerning and include Clostridium difficile and norovirus. Patients with nosocomial diarrhea should be placed in isolation with contact precautions in place until the presence of C difficile infection is determined. Irrespective of etiology, diarrhea can cause serious complications in hospitalized patients, including malnutrition, hemodynamic instability, metabolic acidosis, and potentially fatal pseudomembranous colitis. This article reviews nosocomial diarrhea, including its pathophysiology, infectious and noninfectious causes, and treatment strategies based on identified cause. Source

A pyridine bottle broke in an undergraduate stockroom, spilling two liters of pyridine onto a student, a bench and the floor. Details are discussed about the safety of the student, the subsequent evacuations of laboratories and finally the whole science building. Remediation of the spill is also discussed. A faculty member with an auto-immune disease was affected by their involvement in the spill cleanup, and the consideration of chemists with auto-immune diseases and their interaction with chemical spills is discussed. © 2015 Division of Chemical Health and Safety of the American Chemical Society.

Extravasation of total parenteral nutrition (TPN) delivered via central lines is a known potential complication, but significant extravasations of infusate into the pleural space when using peripherally inserted central catheters (PICCs) have not been reported in adults. We report 2 cases ofpleural cavity extravasation ofTPN delivered via a PICC. Measurement of the glucose level of the effusate is a quick way to determine the presence of TPN and should be considered in any patient receiving TPN via any type of central line with a rapidly developing effusion.

Uphill running represents a frequently used and often prescribed training tactic in the development of competitive distance runners but remains largely uninvestigated and unsubstantiated as a training modality. The purpose of this investigation included documenting the effects of uphill interval training compared with level-grade interval training on maximal oxygen consumption (V̇O2max), the running speed associated with V̇O 2max (Vmax), the running speed associated with lactate threshold (VLT), and the duration for which Vmax can be sustained (Tmax) in well-trained distance runners. Thirty-two well-trained distance runners (age, 27.4 ± 3.8 years; body mass, 64.8 ± 8.9 kg; height, 173.6 ± 6.4 cm; and V̇O2max, 60.9 ± 8.5 ml.min-1.kg-1) received assignment to an uphill interval training group (GHill = 12), level-grade interval training group (GFlat = 12), or control group (GCon = 8). GHill and GFlat completed 12 interval and 12 continuous running sessions over 6 weeks, whereas GCon maintained their normal training routine. Pre-and posttest measures of V̇O2max, Vmax, VLT, and Tmax were used to assess performance. A 3 × 2 repeated measures analysis of variance was performed for each dependent variable and revealed a significant difference in Tmax in both GHill and GFlat (p < 0.05). With regard to running performance, the results indicate that both uphill and level-grade interval training can induce significant improvements in a run-to-exhaustion test in well-trained runners at the speed associated with V̇O2max but that traditional level-grade training produces greater gains. © 2013 National Strength and Conditioning Association.
