Clonal populations of hematopoietic cells with paroxysmal nocturnal hemoglobinuria phenotype in patients with splanchnic vein thrombosis

2014

Abstract Introduction Splanchnic vein thrombosis (SVT) is a serious complication in patients with paroxysmal nocturnal hemoglobinuria (PNH). Mutant PNH clones can be associated with an increased risk of SVT even in the absence of overt disease, but their prevalence in non-selected SVT patients remains unknown. Materials and Methods Patients with objective diagnosis of SVT and without known PNH were tested for the presence of PNH clone using high-sensitivity flow cytometric analysis. Results A total of 202 SVT patients were eligible, 58.4% were males, mean age was 54.6 years (range 17–94), site of thrombosis was portal in 103 patients, mesenteric in 67, splenic in 37, and supra-hepatic in 10…

Impact of psychological risk factors on disaster rescue operations: the case of Italian volunteers.

2007

This paper reports on research into the characteristics of emergency rescue workers, with a focus on psychological distress. We present the results of a study of volunteers from the Italian national civil protection programme. A questionnaire was administered to 2,576 subjects from all over Italy. Most respondents were men, mostly unemployed, whose average level of education was higher than that among most Italian volunteers. Many were poorly endowed with basic skills, with large differences according to geography. Many expected to convert their volunteer activities into permanent jobs. Using this data, we employed a logistical regression model to analyse the risk of low, moderate and sever…

Permanent Stoma After Low Anterior Resection for Rectal Cancer

2010

BACKGROUND AND OBJECTIVES: A low anterior resection procedure for removing a rectal tumor aims to preserve the sphincter and avoid a permanent stoma. Permanent stomas are primarily necessary in cases of poor anorectal function and local recurrence. The aim of this study was to clarify whether anastomosis-related complications and local recurrence influenced the rate of permanent stomas in a long-term follow-up. METHODS: Of 1032 consecutive patients with rectal cancer, 397 were treated by low anterior resection (R0 and R1 resections) between 1985 and 2007 at the Department of General and Abdominal Surgery of the University Hospital, Mainz (Germany). All patient data were collected prospectiv…

Incidence, Presentation, and Prognosis of Small Bowel Adenocarcinoma in Patients with Small Bowel Crohn's Disease: A Prospective Observational Study.

2013

International audience; BACKGROUND:: Patients with Crohn's disease (CD) of the colon are at risk for colorectal cancer and should be screened for dysplasia and cancer of the colon. Small bowel adenocarcinoma (SBA) is a complication of small bowel CD and carries a poor prognosis. However, there is no screening test for SBA in patients with small bowel CD. The aim of this study was to assess the risk and incidence of SBA in a large prospective cohort of patients with small bowel CD and to compare it with the risk of colorectal cancer in patients with CD involving the colon, recruited in the same cohort. METHODS:: In a nationwide French cohort, 11,759 patients with CD were enrolled by 680 gast…

Major urinary dysfunction after mesorectal excision for rectal carcinoma

2004

Abstract Background Urinary dysfunction may occur after mesorectal excision and pelvic autonomic nerve preservation (PANP) in patients with rectal carcinoma. The aim of this prospective study was to identify factors predictive of long-term urinary catheterization. Methods Two hundred and ten patients without significant urological problems underwent resection of rectal cancer with mesorectal excision. The number of patients with complete, partial or no identification of the nerves was documented and correlated with possible predictive factors for postoperative major urinary dysfunction. Results Eight patients (3·8 per cent) required long-term urinary catheterization: two after complete PANP…

Survival differences between European and US patients with colorectal cancer: role of stage at diagnosis and surgery

2005

Background: Population based colorectal cancer survival among patients diagnosed in 1985–89 was lower in Europe than in the USA (45% v 59% five year relative survival). Aims: To explain this difference in survival using a new analytic approach for patients diagnosed between 1990 and 1991. Subjects: A total of 2492 European and 11 191 US colorectal adenocarcinoma patients registered by 10 European and nine US cancer registries. Methods: We obtained clinical information on disease stage, number of lymph nodes examined, and surgical treatment. We analysed three year relative survival, calculating relative excess risks of death (RERs, referent category US patients) adjusted for age, sex, site, …

A combined marker of early non-improvement and the occurrence of melancholic features improve the treatment prediction in patients with Major Depress…

2017

Abstract Background Early Improvement of depressive symptoms within two weeks of antidepressant treatment is a highly sensitive but less specific predictor of later treatment outcome. The aim of this study was to identify clinical features at treatment initiation which are associated with early improvement and non-improvement as well as to identify variables predicting non-remission in patients showing an early improvement. Methods 889 patients with a major depressive episode according to DSM-IV who had participated in an antidepressant treatment trial served as study sample. Clinical predictors (demographic variables, psychopathology, comorbid disorders) were analysed in 698 (79%) early im…

Serum uric acid as an independent predictor of mortality in patients with angiographically proven coronary artery disease.

2002

It is a matter of controversy as to whether uric acid is an independent predictor of mortality in patients with coronary artery disease (CAD) or whether it represents only an indirect marker of adverse outcome by reflecting the association between uric acid and other cardiovascular risk factors. Therefore, we studied the influence of uric acid levels on mortality in patients with CAD. In 1,017 patients with angiographically proven CAD, classic risk factors and uric acid levels were determined at enrollment. A follow-up over a median of 2.2 years (maximum 3.1) was performed. Death from all causes was defined as an end point of the study. In CAD patients with uric acid levels303 micromol/L (5…

The PAI-1 gene locus 4G/5G polymorphism is associated with a family history of coronary artery disease.

1998

Abstract —A family history of ischemic events is a major determinant of coronary artery disease (CAD). Plasma levels of plasminogen activator inhibitor 1 (PAI-1) modulate this risk. A deletion/insertion polymorphism within the PAI-1 locus (4G/5G) affects the expression of this gene. We investigated the relationship between the PAI-1 4G/5G polymorphism in 1179 healthy employees of our institution and the occurrence of CAD in their first-degree relatives. A family history of documented ischemic coronary disease was assessed by a modified WHO questionnaire. The PAI-1 4G/5G polymorphism was evaluated by polymerase chain reaction and endonuclease digestion. The group with a first-degree relativ…

ObjectiveLittle is known on optimal screening population for detecting new atrial fibrillation (AF) in the community. We describe characteristics and estimate cost-effectiveness for a single timepoint electrocardiographic screening.MethodsWe performed a 12-lead ECG in the German population-based Gutenberg Health Study between 2007 and 2012 (n=15 010), mean age 55±11 years, 51% men and collected more than 120 clinical and biomarker variables, including N-terminal pro B-type natriuretic peptide (Nt-proBNP), risk factors, disease symptoms and echocardiographic variables.ResultsOf 15 010 individuals, 466 (3.1%) had AF. New AF was found in 32 individuals, 0.2% of the total sample, 0.5% of indivi…
