BACKGROUND Hospital readmissions are gathering increasing attention as a measure of health care quality and as a cost-saving target. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) recently began collecting data related to 30-day postoperative readmissions. Our objectives were to assess the accuracy of the ACS(More)
Readmission rates after intestinal surgery have been notably high, ranging from 10 % for elective surgery to 21 % for urgent/emergent surgery. Other than adherence to established strategies for decreasing individual postoperative complications, there is little guidance available for providers to work toward reducing their postoperative readmission rates.(More)
OBJECTIVES To assess national adherence with extended venous thromboembolism (VTE) chemoprophylaxis guideline recommendations after colorectal cancer surgery. BACKGROUND Postoperative VTE remains a major cause of morbidity and mortality after abdominal cancer surgery. On the basis of the results from randomized controlled trials, since 2007, national(More)
Acquired antimalarial drug resistance produces treatment failures and has led to periods of global disease resurgence. In Plasmodium falciparum, resistance is known to arise through genome-level changes such as mutations and gene duplications. We now report an epigenetic resistance mechanism involving genes responsible for the plasmodial surface anion(More)
We have constructed the first genetic linkage map for the North American arboviral vector Culex tarsalis. 120 F(2) offspring from a cross between two colonies were genotyped using 25 microsatellites and six inter-simple sequence repeat (ISSR) markers. We resolved four linkage groups which likely correspond to two full-length chromosomes and two arms of the(More)
Erythrocytes infected with malaria parasites have increased permeability to various solutes. These changes may be mediated by an unusual small conductance ion channel known as the plasmodial surface anion channel (PSAC). While channel activity benefits the parasite by permitting nutrient acquisition, it can also be detrimental because water-soluble(More)
BACKGROUND Clinical outcomes data are playing an increasingly important role in medical decision-making, reimbursement, and provider evaluation, but there are no documented programs that provide outcomes data to surgical residents as part of a structured curriculum. Our objectives were to develop a national collaborative of training programs to unify the(More)
INTRODUCTION The Accreditation Council for Graduate Medical Education Next Accreditation System will require general surgery training programs to demonstrate outstanding clinical outcomes and education in quality improvement (QI). The American College of Surgeons-National Surgical Quality Improvement Project Quality In-Training Initiative reports the(More)
BACKGROUND The Next Accreditation System and the Clinical Learning Environment Review Program will emphasize practice-based learning and improvement and systems-based practice. We present the results of a survey of general surgery program directors to characterize the current state of quality improvement in graduate surgical education and introduce the(More)
The ESR, Mössbauer, and visible spectra of the undecapeptide of ferricytochrome c (HPp) were measured for both the solid peptide and solutions of the peptide at pH 1.5, 7, and 10. At the low pH, the iron exists in the HPp in the high-spin species. At neutral and alkaline pHs, the low-spin ferric species predominate. The results of these measurements support(More)
