Background— The impact of changing demographics on causes of long-term death after percutaneous coronary intervention (PCI) remains incompletely defined. Methods and Results— We evaluated trends in cause-specific long-term mortality after index PCI performed at a single center from 1991 to 2008. Deaths were ascertained by scheduled prospective surveillance. Cause was determined via telephone interviews, medical records, autopsy reports, and death certificates. Competing-risks analysis of cause-specific mortality was performed using 3 time periods of PCI (1991–1996, 1997–2002, and 2003–2008). Final follow-up was December 31, 2012. A total of 19 077 patients survived index PCI hospitalization, of whom 6988 subsequently died (37%, 4.48 per 100 person-years). Cause was determined in 6857 (98.1%). Across 3 time periods, there was a 33% decline in cardiac deaths at 5 years after PCI (incidence: 9.8%, 7.4%, and 6.6%) but a 57% increase in noncardiac deaths (7.1%, 8.5%, and 11.2%). Only 36.8% of deaths in the recent era were cardiac. Similar trends were observed regardless of age, extent of coronary disease, or PCI indication. After adjustment for baseline variables, there was a 50% temporal decline in cardiac mortality but no change in noncardiac mortality. The decline in cardiac mortality was driven by fewer deaths from myocardial infarction/sudden death ( P <0.001) but not heart failure ( P =0.85). The increase in noncardiac mortality was primarily attributable to cancer and chronic diseases ( P <0.001). Conclusions— This study found a marked temporal switch from predominantly cardiac to predominantly noncardiac causes of death after PCI over 2 decades. The decline in cardiac mortality was independent of changes in baseline clinical characteristics. These findings have implications for patient care and clinical trial design.

Key Points Alternatively polarized macrophages are abundant constituents of the tumor microenvironment in T-cell lymphoproliferative disorders. GATA-3 expression identifies a subset of PTCL, NOS with a distinct cytokine profile and inferior survival.

Abdominal paracentesis complicated by perforation of a penetrating arterial branch is an extremely rare complication. We report 2 patients who presented with abdominal wall pseudoaneurysms following abdominal paracentesis for the evaluation and treatment of their hepatic dysfunction. We subsequently review the treatment modalities and interventions performed in each case.

Abstract Background: The existence, etiology, diagnosis, and treatment of median arcuate ligament syndrome (MALS) have long been subjects of debate. To our knowledge, there have not been any studies assessing the effectiveness of surgical treatment in improving physical and psychological quality of life in pediatric patients. Subjects and Methods: This is an Institutional Review Board–approved prospective study including all patients undergoing surgical treatment of MALS between 2009 and 2012 at our institution. Demographic information, presenting symptoms, radiological imaging, procedure duration, hospital length of stay, and perioperative complications were gathered for analysis. Patients and their parents were asked to complete the Child Health Questionnaire, a physical and psychological health survey, both within 1 week prior to and at least 3 months following their surgery. Results: Six patients underwent laparoscopic release for MALS. The majority of patients were female ( n =5 [83.3%]), with an average age of 15.7±1.5 years. Presenting symptoms lasted on average 16.5±12.7 months prior to treatment. Average pre- and postsurgical ultrasound celiac artery peak velocities with inspiration were 332.0±34.1 cm/second and 224.3±31.2 cm/second, respectively, with a statistically significant decrease of 107.67 cm/second ( P =.03). The average follow-up period from time of surgery to time of quality of life survey completion was 13±11.3 months, with a range of 3–29 months. A significant improvement from pre- to postsurgical scores was observed in the physical functioning ( P =.03), mental health ( P =.03), and self-esteem categories ( P =.03) of the child assessment. Similarly, there was a significant postsurgical improvement in all categories pertaining to the parent's quality of life ( P =.03). Improvement was also seen in the parents' perception of their child's physical functioning ( P =.03), bodily pain/discomfort ( P =.03), mental health ( P =.03), and general health perceptions ( P =.03). No intraoperative or postoperative complications occurred. Conclusions: Our preliminary results demonstrate that laparoscopic median arcuate ligament release for MALS in the pediatric population is safe and effective and improves overall quality of life for the patients and their parents. In carefully selected patients, laparoscopic release for MALS without additional celiac artery reconstruction normalizes blood flow in the celiac artery and improves physical and psychosocial quality of life for the child and his or her parents.

BackgroundWe sought to determine the utility of a magnetic navigation system (MNS) in treating a variety of coronary artery lesions including those that could not be revascularized with standard percutaneous coronary intervention (PCI). MNS may add value in the treatment of tortuous arteries and bifurcation lesions; however its widespread adoption has lagged because of cost and a lack of clear advantage over conventional PCI. We performed a retrospective analysis to determine whether MNS improved procedural success for highly complex lesions.Methods and ResultsOne hundred and forty‐eight patients underwent treatment with MNS at Mayo Clinic, Rochester. Clinical data, angiographic and procedural characteristics, lesion crossing success and outcomes were reviewed. Overall 133 patients underwent successful revascularization with 87% (143) of 164 lesions crossed using MNS alone. Another six lesions required a combination of MNS and conventional devices resulting in overall success of 91% (149/164). Eighteen complex lesions had previously failed PCI and 12 (67%) were successfully treated with MNS. Success after failed PCI was higher (88%) when a frequent user operated MNS, but occasional users also noted incremental success (30%). Twenty‐five chronic total occlusions were included amongst these 164 lesions, with observed antegrade MNS lesion crossing rates of 78% for regular and 14% for occasional users.ConclusionsMNS is a useful adjunct to performance of PCI. This specialized technology has a clear learning curve and can facilitate treatment of highly complex lesions. © 2013 Wiley Periodicals, Inc.

Purpose The American Society of Clinical Oncology (ASCO) has a policy and set of procedures for endorsing recent clinical practice guidelines that have been developed by other professional organizations. Methods The Cancer Care Ontario (CCO) Guideline on Follow-up Care, Surveillance Protocol, and Secondary Prevention Measures for Survivors of Colorectal Cancer was reviewed by ASCO for methodologic rigor and considered for endorsement. Results The ASCO Panel concurred with the CCO recommendations and recommended endorsement, with the addition of several qualifying statements. Conclusion Surveillance should be guided by presumed risk of recurrence and functional status of the patient (important within the first 2 to 4 years). Medical history, physical examination, and carcinoembryonic antigen testing should be performed every 3 to 6 months for 5 years. Patients at higher risk of recurrence should be considered for testing in the more frequent end of the range. A computed tomography scan (abdominal and chest) is recommended annually for 3 years, in most cases. Positron emission tomography scans should not be used for surveillance outside of a clinical trial. A surveillance colonoscopy should be performed 1 year after the initial surgery and then every 5 years, dictated by the findings of the previous one. If a colonoscopy was not preformed before diagnosis, it should be done after completion of adjuvant therapy (before 1 year). Secondary prevention (maintaining a healthy body weight and active lifestyle) is recommended. If a patient is not a candidate for surgery or systemic therapy because of severe comorbid conditions, surveillance tests should not be performed. A treatment plan from the specialist should have clear directions on appropriate follow-up by a nonspecialist.
