Background MRSA represents a considerable health threat to orthopaedic patients. Throughout the last decade, livestock-associated MRSA emerged increasingly in livestock all over Europe. LA-MRSA broke the species barrier, colonizing and causing infections in humans. Nevertheless, to date there are no studies concerning livestock-associated MRSA and orthopaedic patients. Therefore, we aimed to investigate the prevalence of LA-MRSA in a regional orthopaedic department localized in an area with high-density livestock...

BACKGROUND: Intrathecal drug delivery is an attractive option to circumvent the blood-brain barrier for pain management through its increased efficacy of pain relief, reduction in adverse side effects, and cost-effectiveness. Unfortunately, there are limited guidelines for physicians to choose infusion or drug pump settings to administer therapeutic doses to specific regions of the spine or the brain. Although empiric trialing of intrathecal drugs is critical to determine the sustained side effects, currently there is no inexpensive in vitro method to guide the selection of spinal drug delivery parameters...

Objectives: Debate continues on whether leukoreduction alone (LR) is sufficiently similar to leukoreduced cellular products drawn from cytomegalovirus (CMV)-seronegative (SN) donors to minimize the risk of transfusion-transmitted CMV (TT-CMV). We sought to determine the policy, inventory, and practice landscape of the province for TT-CMV mitigation. Methods: A web-based survey was distributed to hospitals in Ontario by Canadian Blood Services to collect data on their policies with respect to TT-CMV prevention...

The migraine aura is characterized by transient focal cortical disturbances causing dramatic neurological symptoms that are usually followed by migraine headache. It is currently not understood how the aura symptoms are related to the headache phase of migraine. Animal studies suggest that cortical spreading depression, the likely mechanism of migraine aura, causes disruption of the blood-brain barrier and noxious stimulation of trigeminal afferents leading to activation of brainstem nuclei and triggering of migraine headache...

Point-of-care (POC) ultrasound refers to the use of portable imaging. Although POC ultrasound is widely available to the neonatologists in Australia and Europe, neonatologists in the United States report limited availability. Our objective was to seek the US neonatologists' perception of barriers and prerequisites in adopting POC ultrasound in neonatal intensive care units. An online survey link was sent via e-mail to 3000 neonatologists included in the database maintained by the American Academy of Pediatrics...

BACKGROUND: Postoperative cognitive dysfunction (POCD) is a significant clinical syndrome. Neuroinflammation is an important pathological process for POCD. However, it is not clear how systemic inflammation induced by surgery on peripheral tissues or organs is transmitted into the brain. We determined whether matrix metallopeptidase 9 (MMP9), a protein that can increase blood-brain barrier permeability, is critical in this transmission. The role of MMP9 in age-dependent cognitive decline was also determined...

In the Western Hemisphere, Zika virus is thought to be transmitted primarily by Aedes aegypti mosquitoes. To determine the extent to which Ae. albopictus mosquitoes from the United States are capable of transmitting Zika virus and the influence of virus dose, virus strain, and mosquito species on vector competence, we evaluated multiple doses of representative Zika virus strains in Ae. aegypti and Ae. albopictus mosquitoes. Virus preparation (fresh vs. frozen) significantly affected virus infectivity in mosquitoes...

AIMS AND OBJECTIVES: This paper aims to provide a contemporary overview of asexuality and the implications this has for health care practice. BACKGROUND: Individuals belonging to sexual minority groups face many barriers in accessing appropriate health care. The term 'sexual minority group' is usually used to refer to Lesbian Gay Bisexual and Transgender (LGBT) individuals. Anecdotal and research evidence suggests that those who identify as asexual have similar poor experiences...

AIMS: To identify factors that influence lack of engagement of young adults with Type 1 diabetes (aged 13-21 years) with structured diabetes education (SDE) to inform and broaden the reach of future SDE. METHODS: A quantitative, cross-sectional survey was undertaken of 227 young people with Type 1 diabetes drawn from 11 health trusts across Northern Ireland and England, deemed to be representative of the wider population. Participants were asked to complete a questionnaire exploring non-attendance, along with the Diabetes Care Profile, the Diabetes Empowerment Scale (Short Form), the Diabetes Knowledge Test and the 12-item General Health Questionnaire...

In this work, we investigated the generation of particles during pure laser and plasma-assisted laser ablation of titanium. Experiments were performed using a NIR picosecond laser at a wavelength of 1030 nm and a pulse duration of 8 ps. For plasma-assisted ablation, an atmospheric pressure dielectric barrier discharge plasma was applied where the process gas was argon. Quantitative particle distributions at sizes from 10 nm to 10 μm were determined. In addition, we evaluated the amount of ablated material via laser scanning microscopy...

Precision glass molding (PGM) can fabricate aspherical lens and irregular optical products in a single step, but its applicability is currently limited by the thermally induced residual stresses and lens shape derivation after molding. To remove this barrier, this paper develops a numerical optimization platform for PGM based on a simplex algorithm and finite element simulation. It was found that the platform can effectively reduce the residual stress in a molded lens through cooling process optimization and minimize the lens shape derivation by die shape compensation...

Keratinocytes undergo a unique type of programmed cell death known as cornification, which leads to the formation of the stratum corneum (SC), the main physical barrier of the epidermis. A defective epidermal barrier is a hallmark of the two most common inflammatory skin disorders, psoriasis, and atopic dermatitis. However, the detailed molecular mechanisms of skin barrier formation are not yet fully understood. Here, we showed that downregulation of phospholipase C (PLC) δ1, a Ca(2+)-mobilizing and phosphoinositide-metabolizing enzyme abundantly expressed in the epidermis, impairs the barrier functions of the SC...

REVIEW

Epithelial mesenchymal transition (EMT), the adoption by epithelial cells of a mesenchymal-like phenotype, is a process co-opted by carcinoma cells in order to initiate invasion and metastasis. In addition, it is becoming clear that is instrumental to both the development of drug resistance by tumour cells and in the generation and maintenance of cancer stem cells. EMT is thus a pivotal process during tumour progression and poses a major barrier to the successful treatment of cancer. Non-coding RNAs (ncRNA) often utilize epigenetic programs to regulate both gene expression and chromatin structure...

The recording of the electrocardiogram (ECG) during Magnetic Resonance Imaging (MRI) acquisition is of great interest and importance. Firstly, MRI acquisition is a relatively slow process, which therefore complicates the imaging of moving organs. Cardiac MRI requires the development of strategies for acquiring high quality images, which is mainly achieved by synchronising the image acquisition with a specific time during the cardiac cycle. The ECG is used to monitor the heart's activity, and the detection of the largest and steepest peak in the cardiac cycle (the QRS complex) triggers the acquisition of slices of the k-space...

The level of granulocyte-macrophage colony-stimulating factor (GM-CSF) increases in some disorders such as vascular dementia, Alzheimer's disease, and multiple sclerosis. We previously reported that in Alzheimer's disease patients, a high level of GM-CSF in the brain parenchyma downregulated expression of ZO-1, a blood-brain barrier tight junction protein, and facilitated the infiltration of peripheral monocytes across the blood-brain barrier. However, the molecular mechanism underlying regulation of ZO-1 expression by GM-CSF is unclear...
