Introduction: Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is an emerging minimally invasive option for pathologic examination of intrathoracic lymphadenopathy as well as for staging lung cancer. Objectives: To evaluate the diagnostic yield and possible learning curve effects on diagnostic performance using EBUS-TBNA in mediastinal lymphadenopathy. Methods: A retrospective

We consider the authentication problem, using the model described by Simmons. Several codes have been constructed using combinatorial designs and finite geometries. We introduce a new way of constructing authentication codes using LFSR-sequences. A central part of the construction is an encoding matrix derived from these LFSR-sequences. Necessary criteria for this matrix in order to give authentic

OBJECTIVE: The incidence of myocardial infarction (MI) has decreased in general but not among younger middle-aged adults. We performed a cohort study of the association between neighbourhood socioeconomic status (SES) at the age of 40 and risk of MI before the age of 50 years. METHODS: All individuals in Sweden were included in the year of their 40th birthday, if it occurred between 1998 and 20

OBJECTIVE: The main objective of this study was to investigate possible predictors of response to cholinesterase inhibitor (ChEI) treatment, including pre-treatment progression rates and levels of the cerebrospinal fluid (CSF) biomarkers. A secondary objective was to evaluate whether treatment with ChEI changed progression. METHODS: Out-patient individuals (n = 191) with the clinical diagnosis of

This paper investigates the relationship between anticipation that employers may discriminate against certain people (not specified, but not specifically the respondent) according to race, colour of skin, religion or cultural background, and self-rated health, adjusting for social capital in the form of generalised (horizontal) trust in other people. It also investigates ethnic differences in anti

A growing public awareness of the potential negative impacts of corporate activities on the natural environment and society compels large companies to invest increasing resources in the communication of their responsible conduct. This article employs Appraisal theory in a comparative analysis of BP’s and IKEA’s 2009 social reports, each company’s record of their non-financial performance. The main

OBJECTIVE:: To evaluate the prognostic implication of changes in postoperative B-type natriuretic peptide (BNP) concentrations in patients undergoing cardiopulmonary bypass for cardiac surgery. DESIGN:: A retrospective analysis of prospectively collected clinical data. SETTING:: Cardiothoracic surgery and an intensive care unit (ICU) in a university hospital. PARTICIPANTS:: The present study inclu

PURPOSE: To report an alternative to the fenestrated stent-graft for preserving blood flow to side branches in the sealing zones of aortic stent-grafts. TECHNIQUE: A covered stent is deployed parallel to the main aortic stent-graft, protruding somewhat proximally, like a chimney, to preserve flow to a vital side branch covered by the aortic stent-graft. Use of a chimney graft makes it possible to

A method to evaluate and recondition lungs ex vivo has been tested on donor lungs that have been rejected for transplantation. In the present paper, we compare early postoperative course between the six patients who received reconditioned lungs and the patients who received conventional donor lungs during the same period of time. During 2006 and 2007, a total of 21 patients underwent double sequen

Background: A moderate elevation of plasma total homocysteine (tHcy) is considered a potential risk factor for Alzheimer's disease (AD). Methods: We have investigated the main determinants (age, renal impairment, cobalamin/folate status and the presence of vascular disease) of plasma tHcy in 326 patients with AD, and also in 281 patients with mild cognitive impairment (MCI), since about half of th

In the method of exterior complex scaling the coordinates of the Hamilton operator are scaled by a constant factor starting at a radius R≠0. We show that this procedure induces a singularity in the kinetic-energy term which must be interpreted as the derivative of a δ function.

Arm lymphedema is a well-known side effect of breast cancer treatment. Studies of the effect of physical exercise on arm lymphedema are very rare. The purpose of this study was to investigate the influence of pole walking on breast cancer-related arm lymphedema when using a compression sleeve. Twenty-six women with unilateral arm lymphedema took part in a clinical study of pole walking on one occa

Purpose We investigated whether active video gaming (AVG) could bring about regular, enjoyable, physical exercise in children treated for brain tumours, what level of physical activity could be reached and if the children's physical functioning improved. Methods Thirteen children, aged 7-17 years, were randomised to either AVG or waiting-list. After 10-12 weeks they crossed-over. Weekly Internet c

Well-differentiated hepatocellular carcinoma (HCC) may resemble benign liver lesions on initial diagnostic work-up. The validity of surgical resection for preoperatively unclear liver lesions was investigated in this study.

Objective: Primary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity and premature death but the underlying mechanisms are incompletely understood. The aim of this study was to investigate if adrenergic dysfunction may be a contributing factor. Patients and methods: Forty-nine patients with mild PHPT (serum calcium 2.7 ± 0.1 mmol/L) and 48 control subjects, matched for age an

We report on a forward RNAi screen in primary human hematopoietic stem and progenitor cells, using pooled lentiviral shRNA libraries deconvoluted by next generation sequencing. We identify MAPK14/p38α as a modulator of ex vivo stem cell proliferation and show that pharmacological inhibition of p38 dramatically enhances the stem cell activity of cultured umbilical cord blood derived hematopoietic c

More knowledge concerning the association between physical activity and objectively measured attributes of the built environment is needed. Previous studies on the association between objectively measured neighborhood walkability, physical activity, and walking have been conducted in the U.S. or Australia and research findings are available from only one country in Europe - Belgium. The first aim
