Inflammatory Bowel Disease as a Precondition for Stroke or TIA: A Matter of Crohn's Disease Rather than Ulcerative Colitis.
2020
Abstract Background As a chronic systemic inflammation may be associated with an increased risk of vascular events, the aim of the present study was to assess the incidence of stroke and transient ischemic attack (TIA) in patients with inflammatory bowel disease over a period of 15 years. Methods This cohort study included patients for whom the initial diagnosis of an inflammatory bowel disease (IBD) (Crohn's disease: CD and ulcerative colitis: UC) was documented anonymously between 2000 and 2015 in 1,262 general practices in Germany. IBD patients were matched to patients without IBD using propensity scores based on age, sex, physician, co-diagnoses and co-therapies. Cox regression models w…
An investigation of the potential association between gastrointestinal viral and bacterial infection and development of intestinal acute graft versus…
2021
It is uncertain whether gastrointestinal (GI) infection caused by viral and bacterial pathogens may predispose to gastrointestinal acute Graft-versus-host disease (aGvHD-GI) in allogeneic hematopoietic stem cell transplant recipients (allo-HSCT). We investigated the potential association between detection of enteropathogenic viruses or bacteria in stools and subsequent occurrence of aGvHD-GI in a cohort of 121 allo-HSCT patients. Eighty-six out of 121 patients (71%) had acute diarrhea and underwent screening for primary GI pathogens by molecular diagnostic methods. One or more GI pathogens were detected in 27 out of the 86 patients with diarrhea (31.3%). Specifically, Clostridioides diffici…
Is There an Indication for Intraoperative MRI in Subtotal Resection of Glioblastoma? A Multicenter Retrospective Comparative Analysis.
2017
Objective Surgery in patients with highly eloquent glioblastoma (GB) remains challenging. The aim of this study was to evaluate influence of use of intraoperative magnetic resonance imaging (iMRI) on extent of resection (EOR), clinical outcome, and survival in patients with preoperatively intended subtotal resection of GB. Methods Retrospective assessment was performed in 3 neurosurgical centers (2008–2013). All patients with primary GB, unilocular growth, and adjuvant radiochemotherapy in whom subtotal resection was intended were included. Imaging data were pseudonymized and volumetrically assessed by a central reviewer. Clinical outcome was evaluated based on complications, new permanent …

Liver transplanted patients with preoperative autoimmune hepatitis and immunological disorders are at increased risk for Post-Transplant Lymphoprolif…
2010
Long term immunosuppression and therapy of acute rejections result in a 20-120-fold increased risk to develop Non Hodgkin lymphoma (NHL). Since immunosuppressive therapy and immunological disorders are major risk factors for the development of NHL in the non-transplant population we aimed to analyze risk factors for PTLD in our cohort of liver transplanted (LT) patients.We analyzed retrospectively 431 patients liver transplanted between 1998 and 2008.PTLD was diagnosed in eleven of 431 patients (2.6%). PTLD, especially late PTLD, was significantly more frequent in patients who received steroids before LT (Kaplan-Meier: p0.001). Moreover PTLD in immunocompromised patients with preoperative s…
Prenatal mercury exposure and birth outcomes
2016
Background: Results regarding the association between mercury exposure and anthropometry at birth, gestational length and placental weight are inconsistent, as is the role of seafood intake in these asso- ciations. Objective: We assessed whether prenatal mercury exposure is associated with anthropometry at birth, placental weight and gestational length in a population with a relatively high exposure to mercury from seafood consumption. Methods: Total mercury (T – Hg) was determined in cord blood from 1869 newborns with birth outcome measures, within the Spanish multicenter INMA cohort from 2004 to 2008. We adjusted cohort speci fi c linear and Cox regression models to evaluate the associati…
Prognostic factors for cryotherapy of colorectal liver metastases.
2004
Abstract Background . Cryotherapy is a local ablative treatment option for non-resectable liver tumours. We aimed to identify prognostic indicators, that may allow better selection or stratification for adjuvant therapies of patients. Methods . Fifty-five patients had cryotherapy for colorectal liver metastases. The patient-, tumour- and operative details were recorded prospectively. Mean follow up was 24 months. A uni- and multivariate analysis for possible prognostic factors was performed. Results . There was a trend towards better survival for patients with unilobar liver metastases, preoperative serum levels of carcinoembrional antigen (CEA) not exceeding 20 ng/ml and patients undergoin…
Competitive interaction between chronic obstructive pulmonary disease and CHA2DS2-VASc score in predicting incident atrial fibrillation
2018
Background: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality, and an emerging risk factor for atrial fibrillation (AF). CHADS2 and CHA2DS2-VASc scores are significantly associated with incident AF independently of other risk factors. The aim of this study was to demonstrate a possible interaction between COPD and CHA2DS2-VASc in predicting incident AF. Methods: This observational prospective cohort study included 4322 Caucasians with cardiovascular risk factors, stratified by CHA2DS2-VASc score (> 2 vs < 2) and presence/absence of COPD. To detect AF appearance, patients underwent, every 6 months, physical examination, standard 12‑lead electrocardiog…
Home parenteral nutrition-associated thromboembolic and bleeding events: results of a cohort study of 236 individuals
2016
UNLABELLED Essentials Sparse or outdated studies focus on thrombotic and bleeding risk in home parenteral nutrition (HPN). 236 HPN patients followed at a single center for a total of 684 patient-years were evaluated. Rates of venous thrombosis and major bleeding, and prevalence of vena cava syndrome are provided. Anticoagulants might reduce thrombosis risk, but population-specific safety concerns remain. SUMMARY Background Home parenteral nutrition (HPN) is necessary for patients with intestinal failure. Recurrent catheter-related thrombosis (CRT) is common, leading to infectious complications, pulmonary embolism, vascular access loss and intestinal transplantation. The efficacy and safety …
Impact of Tips Preliver Transplantation for the Outcome Posttransplantation
2008
The effects of transjugular intrahepatic portocaval shunt (TIPS) on the survival of grafts and patients after liver transplantation (LTx) have only been documented in small series and with only a comparative description with non-TIPS recipients. We evaluated 61 TIPS patients who had a subsequent LTx and compared these with 591 patients transplanted with cirrhosis without TIPS. Pretransplant characteristics were similar between groups. Graft survival at 1, 3 and 5 years post-LTx was 85.2%, 77% and 72.1% (TIPS) and 75.3%, 69.8% and 66.1% (controls). Patient survival at the same points was 91.7%, 85% and 81.7%, respectively (TIPS) and 85.4%, 80.3% and 76.2% (controls). Cox regression showed th…
