Assessment of Functional Connectome in End-Stage Organ Disease Patients After Life-Threatening Surgery

2020

Purpose The purpose of this study was to assess the organization of intrinsic functional brain networks (functional connectome) in neurologically asymptomatic patients with end-stage organ disease who had undergone major surgery for life-threating conditions and compare it to a control group. Materials and Methods Resting-state functional magnetic resonance imaging (rest-fMRI) was performed in 10 adult, post-operative patients with end-stage organ disease. The patients (7 men, 3 women, mean age 57.9 ± 7.4 years) had undergone: n=4 coronary artery bypass graft for heart failure, n=2 orthotopic liver transplantation for non-alcoholic cirrhotic liver failure, n=3 mitral valve repair for heart …

Sportsponsoring als Geschenksimulation und Status-Spiel

2003

Sportsponsoring wird in der Fachliteratur als wirtschaftlich-rational begrundetes Leistungs-Gegenleistungs-Verhaltnis definiert. In der Offentlichkeitsarbeit von Sponsoren ist aber vielfach zu beobachten, dass dieses Austauschverhaltnis als Geschenk dargestellt wird. Im folgenden Beitrag wird an Beispielen belegt, dass dieser Maskierung eines Geschafts als selbstlose Gabe ein anthropologisches Muster zugrunde liegt, das auf einem Prestigedefizit rein wirtschaftlichen Handelns beruht. Daraus resultiert die Notwendigkeit der Akkumulation symbolischen Kapitals in Form eines Firmen- und Markenbilds, das Analogien zur Produktion von Glaubenssystemen und kulturellen Gutern aufweist. Der Wettbewer…

3D DCE-MRI Radiomic Analysis for Malignant Lesion Prediction in Breast Cancer Patients

2022

Rationale and Objectives: To develop and validate a radiomic model, with radiomic features extracted from breast Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) from a 1.5T scanner, for predicting the malignancy of masses with enhancement. Images were acquired using an 8-channel breast coil in the axial plane. The rationale behind this study is to show the feasibility of a radio-mics-powered model that could be integrated into the clinical practice by exploiting only standard-of-care DCE-MRI with the goal of reducing the required image pre-processing (ie, normalization and quantitative imaging map generation).Materials and Methods: 107 radiomic features were extracted from a …

A negative rapid urease test is unreliable for exclusion of Helicobacter pylori infection during acute phase of ulcer bleeding

2003

Abstract Background. The reliability of the rapid urease test has not been proven in patients with peptic ulcer bleeding. Some studies show bad diagnostic results with the rapid urease test for gastrointestinal bleeding. Aims. To evaluate the efficacy of the rapid urease test in patients with bleeding gastric or duodenal ulcers. Patients and methods. A total of 96 patients with acute peptic ulcer bleeding without proton pump inhibitor or antibiotic therapy within the last 14 days before bleeding were included into the study. During index endoscopy, specimens for histological and rapid urease test were obtained from the antrum and corpus mucosa of the stomach. Patients were also investigated…

Stool antigen assay (HpSA) is less reliable than urea breath test for post-treatment diagnosis of Helicobacter pylori infection

2002

Summary Background : The diagnostic yield of the stool antigen test (HpSA) in evaluating the results of Helicobacter pylori eradication therapy is controversial, but many studies have used only the 13C-urea breath test (13C-UBT) as a gold standard which has greatly reduced their relevance. Aim : To compare the reliability of HpSA and 13C-UBT in patients post-treatment using biopsy-based methods as reference tests. Methods : A total of 100 consecutive dyspeptic patients (42 male and 58 female; mean age, 56 ± 18 years) were enrolled in our study. All patients were H. pylori positive on the basis of at least two biopsy-based methods, and underwent 1 week of treatment with various triple therap…

Helicobacter pyloriinfection among children with gastrointestinal symptoms: a high prevalence of infection among patients with reflux oesophagitis

2007

Aim: To investigate the link between H.pylori infection and dyspepsia in children, and association with reflux oesophagitis. Patients and Methods: H.pylori status was detected by rapid urease test and/or culture in 130 consecutive symptomatic children coming for upper gastrointestinal endoscopy: 40 – aged 8–12 years (55% boys); 90 – aged 13–18 years (21% boys). Endoscopic findings were analyzed. H.pylori prevalence in the age group 8–12 years was compared to the prevalence among 55 asymptomatic children, aged 7–12 years (13C–urea breath test). Statistical analysis: χ2 test, Fisher's test, and logistic regression analysis. Results: The prevalence of H.pylori infection among patients with gas…

Diagnostic Accuracy of <sup>13</sup>C-Urea Breath Test in the Diagnosis of <i>Helicobacter pylori</i> Infection in Patients w…

2001

<i>Aims:</i> We investigated the diagnostic properties of the <sup>13</sup>C-urea breath test (<sup>13</sup>C-UBT) prospectively. These are well validated in nonresected patients before and after treatment of <i>Helicobacter pylori</i> infection but not in patients with partial gastric resection due to peptic ulcer disease. <i>Methods:</i> Hospitalized patients with previous gastric resection and indications for upper gastrointestinal endoscopy were recruited for the study. Biopsy specimens were obtained from the fundus mucosa and the gastric remnant adjacent to the gastroenteric anastomosis for histological examination and rapid u…
