Occupation and risk of glioma, meningioma and acoustic neuroma: results from a German case-control study (interphone study group, Germany)
2010
Background: Several epidemiological studies have investigated the association between occupation and brain tumour risk, but results have been inconclusive. We investigated the association between six occupational categories defined a priori: chemical, metal, agricultural, construction, electrical/electronic and transport, and the risk of glioma, meningioma and acoustic neuroma. Methods: In a population-based case-control study involving a total of 844 cases and 1688 controls conducted from 2000 to 2003, detailed information on life-long job histories was collected during personal interviews and used to create job calendars for each participant. Job title, job activity, job number, and the s…
Non-Hodgkin lymphoma and obesity: A pooled analysis from the InterLymph consortium
2008
Nutritional status is known to alter immune function, a suspected risk factor for non-Hodgkin lymphoma (NHL). To investigate whether long-term over, or under, nutrition is associated with NHL, self-reported anthropometric data on weight and height from over 10,000 cases of NHL and 16,000 controls were pooled across 18 case-control studies identified through the International Lymphoma Epidemiology Consortium. Study-specific odds ratios (OR) were estimated using logistic regression and combined using a random-effects model. Severe obesity, defined as BMI of 40 kg m-2 or more, was not associated with NHL overall (pooled OR = 1.00, 95% confidence interval (CI) 0.70-1.41) or the majority of NHL …
Comparison of Different Nodal Staging in Patients With Locally Advanced Mid-low Rectal Cancer After Long-term Neoadjuvant Chemoradiation Therapy.
2019
Background/Aim: The aim of this study was to compare the ability of different lymph nodal staging systems to predict cancer recurrence in a multicenter European series of patients who underwent proctectomy after neoadjuvant chemoradiotherapy for locally advanced rectal cancer. Patients and Methods: Data on 170 consecutive patients undergoing proctectomy after neoadjuvant therapy for cT3-4 or cN+ rectal adenocarcinoma were retrieved from the European MRI and Rectal Cancer Surgery database. The prognostic role of the number of retrieved and examined nodes, nodal ratio, and log odds of positive lymph nodes (LODDS) was analyzed and compared by receiver operating characteristic curves, Pearson t…
Posttraumatic stress, depression and anxiety among adult long-term survivors of cancer in adolescence.
2010
Abstract Background To determine the prevalence of posttraumatic stress, depression and anxiety in adults who have survived cancer (⩾5 years) diagnosed in adolescence, as compared to healthy controls. Patients and methods Survivors (n = 820) of cancer during adolescence (age M = 30.4 ± 6.0 years; M = 13.7 ± 6.0 years since diagnosis) and 1027 matched controls without history of cancer (age M = 31.5 ± 6.9 years) completed standardised questionnaires measuring posttraumatic stress, depression and anxiety. Additionally, sub-groups of 202 survivors and 140 controls with elevated scores received structured interviews to ascertain DSM-IV-diagnoses. Results A total of 22.4% of the survivors report…
Are alcohol intake and smoking associated with mycosis fungoides? A European multicentre case-control study.
2001
The incidence of mycosis fungoides (MF) is low, and the aetiology of the disease is unknown. The aim of this study was to investigate whether wine consumption protects against the disease and whether smoking constitutes a risk factor. This paper is part of the European Rare Cancers Study that tries to determine the risk factors for seven selective rare cancers, including mycosis fungoides, involved in the development of cancer. A multicentre case-control study was conducted in six European countries. Only incident cases with confirmed histology were included in the analysis which include a total of 76 cases of MF and 2899 controls. Wine intake had no protective effect; on the contrary the c…
Radiation response non-invasively imaged by [18F]FDG-PET predicts local tumor control and survival in advanced oral squamous cell carcinoma
2003
It is a major challenge to preoperatively identify patients who will profit from surgery of advanced oral cancer. In multimodality therapy, response to neoadjuvant radiation correlates to treatment success. Hence, for preoperative decisions, assessment of treatment response is required. Therefore, we analysed the prognostic significance of glucose metabolism after preoperative radiotherapy. [(18)F]FDG-PET investigations were performed for re-staging 35 patients after neoadjuvant radiotherapy (36Gy) immediately prior to tumor resection. Emission and transmission measurements were obtained and SUV's were calculated for the sites of maximum [(18)F]FDG-uptake. Subpopulations of "low" (SUV4) and…
Association Between Individual and Combined SNPs in Genes Related to Innate Immunity and Incidence of CMV Infection in Seropositive Kidney Transplant…
2014
In this study, we assessed the association between single-nucleotide polymorphisms (SNPs) in seven candidate genes involved in orchestrating the immune response against cytomegalovirus (CMV) and the 12-month incidence of CMV infection in 315 CMV-seropositive kidney transplant (KT) recipients. Patients were managed either by antiviral prophylaxis or preemptive therapy. CMV infection occurred in 140 patients (44.4%), including 13 episodes of disease. After adjusting for various clinical covariates, patients harboring T-allele genotypes of interleukin-28B (IL28B) (rs12979860) SNP had lower incidence of CMV infection (adjusted hazard ratio [aHR]: 0.66; 95% confidence interval [CI]: 0.46-0.96; p…
Effect of desquamative gingivitis on periodontal status: a pilot study
2009
OBJECTIVE: Desquamative gingivitis (DG) represents the gingival manifestation associated with several mucocutaneous disorders and systemic conditions. Little is known of whether or not DG could influence the onset or progression of plaque-related periodontitis. In this study, the potential impact of DG on plaque-related attachment loss and pocket formation has been evaluated. METHODS: A cross-sectional evaluation of 12 patients with DG [eight oral lichen planus (OLP), four mucous membrane pemphigoid (MMP)], never treated for DG lesions or plaque-related periodontitis, was carried out. Probing depth (PD), clinical attachment loss (CAL), fullmouth plaque (FMPS), and bleeding (FMBS) scores wer…
Distributed BOLD-response in association cortex vector state space predicts reaction time during selective attention.
2006
Human cortical information processing is thought to be dominated by distributed activity in vector state space (Churchland, P.S., Sejnowski, T.J., 1992. The Computational Brain. MIT Press, Cambridge.). In principle, it should be possible to quantify distributed brain activation with independent component analysis (ICA) through vector-based decomposition, i.e., through a separation of a mixture of sources. Using event-related functional magnetic resonance imaging (fMRI) during a selective attention-requiring task (visual oddball), we explored how the number of independent components within activated cortical areas is related to reaction time. Prior to ICA, the activated cortical areas were d…
An approach to single trial analysis of event-related potentials based on signal detection theory.
1996
Abstract The aim of the present paper was to introduce a single trial analysis to event-related potential measurement in order to illuminate the mechanisms behind an impaired P300 amplitude occurring under certain experimental conditions. For this purpose we applied tools from linear system theory and signal detection theory to single trials in an oddball paradigm in order to estimate the amplitude of the positive deflection around the P300 latency following target and nontarget stimuli. According to the density functions of these amplitude distributions we operationally defined ‘P300 absent in target’ (P300 amplitude smaller than an individual threshold under target conditions) as well as …
