Mark I Garvey, Craig W Bradley, Elisabeth Holden, Mike Weibren
Pseudomonas aeruginosa is an important nosocomial pathogen commonly colonising hospital water supplies. HTM 04-01 addresses the risk posed by recommending water testing in augmented care areas which includes outpatient haemodialysis. We discuss how two teaching hospitals independently reviewed the risk to outpatient haemodialysis patients drawing the same conclusion. The highest number of infection episodes with P. aeruginosa was seen in critical care followed by burns and haematology with the lowest in haemodialysis...

BACKGROUND: Statins are commonly prescribed for the secondary prevention of ischemic stroke, but there is conflicting evidence as to whether they increase the risk of intracranial hemorrhage. Lipophilic statins cross the blood-brain barrier more freely than hydrophilic statins and may therefore increase the risk of intracranial hemorrhage. OBJECTIVE: To determine whether, in older patients following ischemic stroke, receipt of lipophilic statins was associated with differences in the risk of intracranial hemorrhage...

Background: Autosomal dominant polycystic kidney disease (ADPKD) affects 12.5 million worldwide. Vasopressin drives cysts growth and in animal models can be suppressed through high water intake. A randomized controlled trial of 'high' versus 'standard' water intake in ADPKD is essential to determine if this intervention is beneficial. We conducted an ADPKD patient survey to gain an understanding of current fluid intake practices and the design challenges of a randomized water intake trial. Methods: In collaboration with the PKD Charity, we developed and distributed an online survey to ADPKD patients over age 16 years and not on renal replacement therapy...

Here, we demonstrated the electrospinning of polymer-free nanofibrous webs from inclusion complex (IC) between hydroxypropyl-β-cyclodextrin (HPβCD) and Vitamin E (Vitamin E/HPβCD-IC NF). The inclusion complexation between HPβCD and Vitamin E was prepared by using two different molar ratio (Vitamin E: HPβCD; 1:2 and 1:1), which correspond to theoretical value of ~13% (w/w) and 26% (w/w) loading of Vitamin E in the nanofiber (NF) matrix. After electrospinning and storage, a very high loading of Vitamin E (up to ~11% w/w, with respect to fiber matrix) was preserved in Vitamin E/HPβCD-IC NF...

Antibiotic-resistance by bacteria is a growing global concern within the healthcare field, and it has provided an impetus for continued antimicrobial development. Pyrinezolid (PZ), a novel oxazolidinone compound, can effectively inhibit most gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE). Though PZ is a promising antimicrobial candidate, the druggability of PZ is limited by its poor water solubility. Therefore, the amphipathic mPEG-PLLA copolymer was used to prepare the pyrinezolid micelles (PZ-M)...

Neonatal herpes simplex virus (NHSV) infections are associated with significant morbidity and mortality. Numerous factors influence the transmission of HSV infection to newborns; however, immersion in water during labor has received very little attention as a possible risk factor despite the increasing popularity of water births. We report a case of disseminated NHSV type 1 infection, possibly acquired during a water birth. The purpose of this report is to alert healthcare providers to this potential route of transmission and to highlight the importance of screening guidelines for HSV before a water birth...

Polypharmacy is the consequence of multimorbidity. Both phenomena may cause functional limitations and/or frailty and/or care dependency in older people. In the human body, a medicament undergoes at least 3 important actions: absorption, distribution and elimination. These actions may proceed aberrantly in older people. Following interaction with receptors, a medicament triggers a chain reaction in the human body. The receptors and each link of the chain reaction may be subject to changes due to diseases as well as ageing...

Skin-mountable chemical sensors using flexible chemically sensitive nanomaterials are of great interest for electronic skin (e-skin) application. To build these sensors, the emerging atomically thin two-dimensional (2D) layered semiconductors could be a good material candidate. Herein, we show that a large-area WS2 film synthesized by sulfurization of a tungsten film exhibits high humidity sensing performance both in natural flat and high mechanical flexible states (bending curvature down to 5 mm). The conductivity of as-synthesized WS2 increases sensitively over a wide relative humidity range (up to 90%) with fast response and recovery times in a few seconds...
