Magnetic resonance imaging for verifying hip fracture diagnosis why, when and how?

Introduction: Hip fractures are commonly diagnosed by plain radiography. When a patient presents with negative radiographs and high clinical suspicion of fracture, guidelines recommend proceeding with magnetic resonance imaging (MRI) to diagnose the patient. The aim of this study was to assess the use of MRI in diagnosing hip fractures following trauma to the hip and describe clinical outcome afte

Seasonal fluctuation in the secretion of the antioxidant melatonin is not associated with alterations in sperm DNA damage

A high sperm DNA fragmentation index (DFI) is associated with reduced fertility. DFI is influenced by the balance between reactive oxygen species and antioxidants. A circannual variation in melatonin, an antioxidant and free radical scavenger, could thus impact semen quality and fertility. The association between the major melatonin metabolite, urine 6-sulfatoxymelatonin (aMT6s), and DFI was analy

Class : Feminist and cultural perspectives

There is hardly any discussion of class that does not in some way relate to the theories of Marx and Weber. So profound was the impact of their ideas, that their writings are often perceived as the only original and most reliable interpretations of class society. But Marx and Weber were neither the first, nor last, to talk about class and they did so based on the specific conditions prevalent in t

DNA-fragmentation is a source of bactericidal activity against Pseudomonas aeruginosa

Pseudomonas aeruginosa airway infection is common in cystic fibrosis (CF), a disease also characterized by abundant extracellular DNA (eDNA) in the airways. The eDNA is mainly derived from neutrophils accumulating in the airways and contributes to a high sputum viscosity. The altered environment in the lower airways also paves the way for chronic P. aeruginosa infection. Here, we show that mice wi

Incidence of Hospital Norovirus Outbreaks and Infections Using 2 Surveillance Methods in Sweden

OBJECTIVE To evaluate 2 different methods of surveillance and to estimate the incidence of norovirus (NoV) outbreaks in hospitals. DESIGN Prospective observational study. SETTING All 194 hospital wards in southern Sweden during 2 winter seasons (2010-2012). METHODS Clinical surveillance based on outbreak reports of 2 or more clinical cases, with symptom onset within 5 days, was compared with labor

Knowledge Dump : that's not what I wiped, griped, sniped, TYPED. A Consideration of the Pedagogical Implications of Using Word Processors and their Affect on Writing

We all learned how to shape letters in different ways; with a pencil or crayon, or maybe by writing in the sand. However, basic handwriting must be understood and accomplished before graduating into the difficult skill of cursive handwriting. Professor Chris Dede relates that technologies can unobtrusively alter how we process information and express ourselves. (2012) Today, the computer is used m

Coeliac patients detected during type 1 diabetes surveillance had similar issues to those diagnosed on a clinical basis

Aim: Screening children with type 1 diabetes for coeliac disease is controversial, because they often appear asymptomatic. Our aim was to establish whether active screening should be recommended. Methods: This study focused on 22 children whose coeliac disease was detected by serological screening during diabetes surveillance and 498 children diagnosed because of a clinical suspicion. We compared

On the Fence with the New Liberal Arts : Student Reflections on Teaching Media for Expression and Communication

The author spent seven years teaching and tutoring basic media use to liberal arts students. During this time, the author noted that liberal arts students differ in their use of technology, both in basic technical comprehension and computer skills levels, as compared to technical and computer science students. Different pedagogical approaches for the liberal arts students for the period of 2003-20

Conditional estimation in two-stage adaptive designs

We consider conditional estimation in two-stage sample size adjustable designs and the consequent bias. More specifically, we consider a design which permits raising the sample size when interim results look rather promising, and which retains the originally planned sample size when results look very promising. The estimation procedures reported comprise the unconditional maximum likelihood, the c

Molecular mechanisms underlying lineage bias in aging hematopoiesis

Although hematopoietic stem cells (HSCs) have traditionally been thought to possess the ability to give rise to all the mature cell types in the hematopoietic system, this conception of hematopoiesis was based on evaluation of hematopoietic output from large numbers of HSCs using transplantation models. More recent studies evaluating HSCs at the clonal or near-clonal level, both in transplantation

The association between gaba-modulators and clostridium difficile infection - A matched retrospective case-control study

Objective Recently, metabolomics studies have suggested that the neurotransmitter ã-amino butyric acid (GABA) may modulate C. difficile infection (CDI) pathogenesis. In the present study, we investigated the association between GABA-modulating pharmaceuticals and CDI development. Methods In July-December 2013, we performed a matched, retrospective case-control study in Skåne county, Sweden, to ass
