Classification Scheme for ductal morphology in cyanotic patients with ductal dependent pulmonary blood flow and association with outcomes of patent ductus arteriosus stenting
Catheterization and Cardiovascular Interventions, 2019Co-Authors: Athar M Qureshi, Bryan H Goldstein, Andrew C Glatz, Hitesh Agrawal, Varun Aggarwal, Allen R Ligon, Courtney Mccracken, Alicia Mcdonnell, Timothy M Buckey, Wendy WhitesideAbstract:OBJECTIVES: To devise a Classification Scheme for ductal morphology in patients with ductal dependent pulmonary blood flow (PBF) that can be used to assess outcomes. BACKGROUND: The impact of ductal morphology on outcomes following patent ductus arteriosus (PDA) stenting is not well defined. METHODS: Patients 1 stent did not differ based on TI. Greater TI was associated with pulmonary artery (PA) jailing (p = 0.003). Twelve (11.4%) patients underwent unplanned reintervention, more commonly with greater TI (p = 0.022) and PA jailing (p < 0.001). At the time of subsequent surgical repair/palliative staging, PA arterioplasty was performed in 32 patients, more commonly when a PA was jailed (p = 0.048). PA jailing did not affect PA size at follow up. CONCLUSIONS: The proposed qualitative and quantitative PDA morphology Classification Scheme may be helpful in anticipating outcomes in patients with ductal dependent PBF undergoing PDA stenting.

Background The impact of ductal morphology on outcomes following patent ductus arteriosus (PDA) stenting is not well defined. Methods Patients Results One hundred and five patients underwent PDA stenting. TI was Type I in 58, Type II in 24, and Type III in 23 PDAs, respectively. There was a significant association between ductal origin and vascular access site (p 1 stent did not differ based on TI. Greater TI was associated with pulmonary artery (PA) jailing (p = 0.003).

risk prediction for development of pancreatic fistula using the isgpf Classification Scheme
World Journal of Surgery, 2008Co-Authors: Wande B Pratt, Mark P Callery, Charles M VollmerAbstract:Background: The International Study Group on Pancreatic Fistula (ISGPF) Classification Scheme has become a useful system for characterizing the clinical impact of pancreatic fistula. We sought to identify predictive factors that predispose patients to fistula, specifically those with clinical relevance (grades B/C), and to describe the clinical and economic significance of risk stratification within this framework.

clinical and economic validation of the international study group of pancreatic fistula isgpf Classification Scheme
Annals of Surgery, 2007Co-Authors: Wande B Pratt, Mark P Callery, Tsafrir Vanounou, Zhen S Huang, Shishir K Maithel, Charles M VollmerAbstract:Pancreatic fistula is widely regarded as the most ominous of complications following pancreatic resection. Its clinical impact and sequelae have been previously described and shown to contribute to the development of other morbid complications and high rates of mortality.1–4 Despite refinements in operative technique and advancements in postoperative management, fistulas still occur with a frequency of 5% to 30%.5–12 Efforts to mitigate this problem have included technical considerations (modification of the pancreatico-jejunal anastomosis technique, reconstruction with pancreaticogastrostomy, and placement of pancreatic duct stents), perioperative infusion of somatostatin analogues, and use of adhesive sealants.9 However, the successes of these various techniques and pharmacologic adjuvants is frequently challenged, and dissension exists as to which methods are optimal for prevention and management of fistulas. The debate is further compounded by numerous and widely varying definitions of pancreatic fistula. Data from a recent analysis of 4 widely accepted definitions of fistula reported in the gastrointestinal surgical literature demonstrates that fistula rate depends largely upon the definition used.13 The lack of a universal definition of pancreatic fistula, therefore, precludes objective comparisons of surgical experiences with this complication. To address this problem and develop a consensus approach, an international consortium of 37 leading pancreatic surgeons from 15 countries, the International Study Group on Pancreatic Fistula (ISGPF), convened, reviewed the literature, and discussed their surgical experiences with fistulas.14 The result was a universal and applicable definition of pancreatic fistula and a grading system for fistula severity based on clinical impact on the patient. Appraisal of this grading system has yet to be accomplished, and to date, the ISGPF clinical Classification Scheme has not been rigorously tested or validated. The aims of this study, therefore, are: 1) to analyze our experience with pancreatic fistula by applying the ISGPF Classification Scheme in a high-volume pancreatico-biliary surgical specialty unit; 2) to demonstrate its value in examining outcomes in a large cohort of patients undergoing pancreaticoduodenectomy; and 3) to validate its application, clinically and economically, as a suitable alternative to current biochemical definitions of fistula.

the university of minnesota cancer prevention research unit vegetable and fruit Classification Scheme united states
Cancer Causes & Control, 1995Co-Authors: Stephanie A Smith, Deborah R Campbell, Patricia J Elmer, Margaret C Martini, Joanne L Slavin, John D PotterAbstract:High vegetable and fruit (VF Total Vegetables; Total Fruits; and two groups orthogonal to these-the Botanical and Phytochemical groups. Subgroups are specified within each main group. V&F exposure is quantified as the absolute amount consumed (weight) or as the number of household servings. This Classification Scheme has public health applications and may be used to examine associations with chronic diseases other than cancer.
