Human Pathology | Year: 2013
Despite strong experimental evidence, BK polyomavirus involvement in human cancers has been controversial. We report 2 cases of kidney ± pancreas transplant recipients with evidence of BK polyomavirus reactivation, who developed aggressive urinary bladder urothelial carcinomas with adenocarcinomatous and/or micropapillary differentiation. Diffuse strong nuclear positivity for viral T antigen, p53, Ki-67, and p16 was observed in both malignancies. The BK polyomavirus role in promoting urothelial neoplasia in transplant recipients may be partly indirect, based on the demonstration by polymerase chain reaction in both tumors of BK polyomavirus with intact open reading frames and close phylogenetic clustering with known replication- competent strains, and viral capsid protein VP1 messenger RNA and intranuclear virions by electron microscopy in 1 tumor. No unique cancer-associated mutations were found, but some viral T antigen mutations were potentially associated with increased rate of viral replication and risk for "rare" carcinogenic events. The BK polyomavirus-induced profound effects on cell activation, cell cycle shift to proliferation, and apoptosis inhibition, in the context of marked immunosuppression, constitute a potentially ideal background for malignant transformation. The long time lapse between transplantation and tumor manifestation, 7 and 11 years, respectively, further supports the concept of multistep carcinogenesis cascade and long-term risk for these patients. We propose a model of changes ranging from viral reactivation to dysplasia to invasive carcinoma. Clinical vigilance is warranted for early diagnosis of BK polyomavirus-related urothelial malignancies in transplant recipients. © 2013 Elsevier Inc. All rights reserved.

Objective: To determine pre-/intraoperative risk factors for anastomotic leak after colon resection for cancer and to create a practical instrument for predicting anastomotic leak risk. Background: Anastomotic leak is still the most dreaded complication in colorectal surgery. Many risk factors have been identified to date, but multicentric prospective studies on anastomotic leak after colon resection are lacking. Methods: Fifty-two hospitals participated in this prospective, observational study. Data of 3193 patients, operated for colon cancer with primary anastomosis without stoma, were included in a prospective online database (September 2011-September 2012). Forty-two pre-/intraoperative variables, related to patient, tumor, surgical procedure, and hospital, were analyzed as potential independent risk factors for anastomotic leak (60-day follow-up). A nomogram was created to easily predict the risk of anastomotic leak for a given patient. Results: The anastomotic leak rate was 8.7%, and widely varied between hospitals (variance of 0.24 on the logit scale). Anastomotic leak significantly increased mortality (15.2% vs 1.9% in patients without anastomotic leak, P < 0.0001) and length of hospitalization (median 23 vs 7 days in uncomplicated patients, P < 0.0001). In the multivariate analysis, the following variables were independent risk factors for anastomotic leak: obesity [P = 0.003, odds ratio (OR) = 2.7], preoperative serum total proteins (P = 0.03, OR = 0.7 per g/dL), male sex (P = 0.03, OR = 1.6), ongoing anticoagulant treatment (P = 0.05, OR = 1.8), intraoperative complication (P = 0.03, OR = 2.2), and number of hospital beds (P = 0.04, OR = 0.95 per 100 beds). Conclusions: Anastomotic leak after colon resection for cancer is a frequent, relevant complication. Patients, surgical technique, and hospital are all important determining factors of anastomotic leak risk. © 2015 Wolters Kluwer Health, Inc.

Peripheral psoriatic arthritis is an inflammatory and progressive disease; its burden, either at the structural level or the function and quality of life, is similar to other chronic poliarthritidies. In spite of treatment with synthetic or biologic DMARDs, remission is only achieved in about 30% of the patients. From a clinical point of view, persistent joint activity (tender and swollen joints) is a factor leading to joint damage progression. These data indicate the need for a tight follow up and treatment of the patients. © 2011 Elsevier España, S.L..

Osteoarthritis and Cartilage | Year: 2010
Objective: Osteoarthritis (OA) is the most common rheumatic pathology. It is related to aging and is characterized primarily by cartilage degradation. Despite its high prevalence, the diagnostic methods currently available are limited and lack sensitivity. The focus of this review is the application of proteomic technologies in the search of new biomarkers for improved diagnosis, prognosis and treatment of OA. Methods: This review focuses on the utilization of proteomics in OA biomarker research to enable early diagnosis, improved prognosis and the application of tailored treatments. Results: New diagnostic tests for OA are urgently needed and would also promote the development of alternative therapeutic strategies. Considering that OA involves different tissues and complex biological processes, the most promising diagnostic approach would be the study of combinations of biomarkers. New experimental approaches for the identification and validation of OA biomarkers have recently emerged and include proteomic technologies. These techniques allow the simultaneous analysis of multiple markers and become a very powerful tool for both biomarker discovery and validation. Conclusions: Improvements in proteomics technology will undoubtedly lead to advances in characterizing new OA biomarkers and developing alternative therapies. Even so, further work is required to enhance the performance and reproducibility of proteomics tools before they can be routinely used in clinical trials and practice. © 2010 Osteoarthritis Research Society International.

Objective: The purpose of this study is to compare early and long-term results in terms of survival and cardiovascular complications of patients with acute traumatic aortic injury who were conservatively managed with patients who underwent surgical or endovascular repair. Methods: From January 1980 to December 2009, 66 patients with acute traumatic aortic injury were divided into 3 groups according to treatment intention at admission: 37 patients in a conservative group, 22 patients in a surgical group, and 7 patients in an endovascular group. Groups were similar with regard to gender, age, Injury Severity Score, Revised Trauma Score, and Trauma Injury Severity Score. Results: In-hospital mortality was 21.6% in the conservative group, 22.7% in the surgical group, and 14.3% in the endovascular group (P = .57). In-hospital aortic-related complications occurred only in the conservative group. Median follow-up time was 75 months (range, 5-327 months). Conservative group survival was 75.6% at 1 year, 72.3% at 5 years, and 66.7% at 10 years. Surgical group survival remained at 77.2% at 1, 5, and 10 years, whereas survival in the endovascular group was 85.7% at 1 and 5 years (P = .18). No patient in the surgical or endovascular group required reintervention because of aortic-related complications, whereas 37.9% of the conservative group had an aortic-related complication that required surgery or caused the patient's death during the follow-up period. Cumulative survival free from aortic-related complications in the conservative group was 93% at 1 year, 88.5% at 5 years, and 51.2% at 10 years. Cox regression confirmed the initial type of aortic lesion (hazard ratio, 2.94; P = .002) and a Trauma Score-Injury Severity Score greater than 50% on admission (hazard ratio, 1.49; P = .042) as risk factors for the appearance of aortic-related complications. Two peaks in the complication rate of the conservative group were detected in the first week and between the first and third months after blunt thoracic trauma. Conclusions: The advent of thoracic aortic endografting has enabled a revolution in the management of acute traumatic aortic injury in patients with multisystem trauma with a low in-hospital morbimortality. Nonoperative management may be only a therapeutic option with acceptable survival in carefully selected patients. The natural history of these patients has revealed a marked trend of late aortic-related complications developing, which may justify an endovascular repair even in some low-risk patients.

Team-focused intervention to improve the care of low-risk patients with community-acquired pneumonia (CAP) is a matter of controversy. Our aim was to determine if a community-acquired pneumonia team (CAPT) would shorten hospital length of stay (LOS) and improve health care utilization in low-risk patients with CAP compared with management by a general pulmonary team (GPT). We performed a prospective cohort study of hospitalized, low-risk patients with CAP (Pneumonia Severity Index [PSI] score class I or II) at a single tertiary hospital from June 2007 to June 2008. Study patients were stratified to management by the CAPT treating group (n = 35), following the Infectious Diseases Society of America (IDSA) and American Thoracic Society (ATS) CAP guideline recommendations, or to management by the GPT (n = 30) following the standard of care. Primary outcome measure for comparison of the efficacy of the 2 different team-focused interventions was hospital LOS for patients with CAP. Secondary study outcome measures included patient 30- and 90-day all-cause readmission rate, rate of mortality at 30 and 90 days, antibiotic-treatment duration, time to switch patient from intravenous (IV) to oral antibiotic treatment, and time to achieve clinical stability for patients. Hospitalized, low-risk patients with CAP, who were assisted by a CAPT were more likely to have a shorter hospital stay (9 days less; P < 0.001), shorter time to switch from IV to oral antibiotic therapy (8 days less; P <0.001), and total shorter duration of antibiotic treatment (6 days less; P <0.001), when compared with low-risk patients with CAP who were assisted by a GPT. In addition, for both groups of assisted patients, there were no differences in the time to achieve clinical stability, use of guideline-concordant antibiotic therapy, rate of mortality, or rate of readmissions at 30 and 90 days. Management by a dedicated CAPT reduced patient hospital LOS, time to switch from IV to oral antibiotic therapy, and duration of antibiotic treatment, without causing adverse events, compared with standard of care, in low-risk patients with CAP.

Immunosuppression in transplantation has experienced changes in recent years as a result of the introduction of new drugs that act upon the different pathways of the host immune response with the purpose of securing more individualized immune suppression, with fewer side effects.Although following in the steps of other solid organ transplant modalities, lung transplantation, because of its special characteristics, has not yielded similar middle- and long-term results.Improved understanding of the underlying rejection mechanisms, the pharmacodynamic control of drugs, new administration routes designed to reduce the side effects, and new drug substances or immune modulating processes will all contribute to improve the expectations associated to lung transplantation in the near future. © 2012 Elsevier España, S.L. and SEMICYUC.

Transversus abdominis plane block has become an important method of postoperative pain management for patients undergoing abdominal surgery but the modest duration is a major limitation. We report the successful use of a novel TAP catheter technique for continuous infusion of levobupivacaine in six gynecologic and obstetric patients. Bilateral TAP catheters were inserted at the end of surgery by ultrasound imaging using a Contiplex® C needle (B. Braun, Melsungen, Germany) in the Triangle of Petit or in a postero-subcostal level based on the location of the surgical incision. Following negative aspiration, 0.25% levobupivacaine 5mL was injected. After withdrawing the needle, while holding the over-the-needle catheter in place, bilateral continuous infusion of 0.125% levobupivacaine at 2mL/h from elastomeric pumps (INfusor SV2, Baxter, France) was started and continued for up to 50h. Before removal of the catheter, a bolus of 10mL levobupivacaine 0.25% was administered.Successful analgesia was achieved in all six cases utilizing continuous infusión of levobupivacaine, minimizing the volume required. TAP infusions produce significant opioid sparing and better patient mobility. This technique may be a reliable alternative to neuraxial analgesia in major gynecological and obstetrical surgery. © 2014 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

AimsAlthough peak may have higher sensitivity than post-treadmill exercise echocardiography (EE) for the detection of coronary artery disease (CAD), its prognostic value remains unknown. We sought to assess the relative values of peak and post-EE for predicting outcome in patients with known/suspected CAD.Methods and resultsWe studied 2947 patients who underwent EE. Wall motion score index (WMSI) was evaluated at rest, peak, and post-exercise. Ischaemia was defined as the development of new or worsening wall motion abnormalities with exercise. Separate analyses for all-cause mortality and major cardiac events (MACE) were performed. Ischaemia developed in 544 patients (18.5). Among them, ischaemia was detected only at peak exercise in 124 patients (23), whereas 414 (76) had ischaemia at peak plus post-exercise imaging and six patients (1) had ischaemia only at post-exercise. During follow-up, 164 patients died. The 5-year mortality rate was 3.5 in patients without ischaemia, 15.3 in patients with peak ischaemia alone, and 14 in patients with post-exercise ischaemia (P < 0.001 normal vs. ischaemic groups). In the multivariate analysis, post-exercise WMSI was an independent predictor of MACE [hazard ratio (HR) 1.87, 95 confidence interval (CI) 1.09-2.19, P = 0.02]. Peak exercise WMSI was an independent predictor of MACE (HR 2.19, 95 CI 1.30-3.69, P = 0.003) and mortality (HR 1.58, 95 CI 1.07-2.35, P = 0.02). The addition of peak EE results to clinical, resting echocardiography, exercise variables, and post-EE provided incremental prognostic information for MACE (P = 0.04) and mortality (P = 0.04).ConclusionPeak treadmill EE provides significant incremental information over post-EE for predicting outcome in patients with known or suspected CAD.

Objective: The aim was to evaluate general anesthesia (GA) plus ilioinguinal nerve block (IIB) versus spinal anesthesia (SA) in patients scheduled for ambulatory inguinal hernia repair regarding pain management, anesthesia recovery and reducing potential complications. Materials and Methods: A double-blind, prospective, randomized, controlled study in patients American Society of Anesthesiologists I-III randomized into two groups: GA plus IIB group, induction of anesthesia with propofol, maintenance with sevoflurane, airway management with laryngeal mask allowing spontaneous ventilation and ultrasound-guided IIB; SA group, patients who underwent spinal block with 2% mepivacaine. The study variables were pain intensity, assessed by visual analog scale, analgesic requirements until hospital discharge, time to ambulation and discharge, postoperative complications-related to both techniques and satisfaction experienced. Results: Thirty-two patients were enrolled; 16 patients in each group. The differences regarding pain were statistically significant at 2 h of admission (P < 0.001) and at discharge (P < 0.001) in favor of the GA plus ilioinguinal block group. In addition in this group, analgesic requirements were lower than SA group (P < 0.001), with times of ambulation and discharge significantly shorter. The SA group had a higher tendency to develop complications and less satisfaction. Conclusion: General anesthesia plus IIB is better than SA regarding postoperative analgesia, time to mobilization and discharge, side-effect profile and satisfaction experienced by the patients.
