BACKGROUND: Dementia is a chronic, progressive and ultimately fatal neurodegenerative disease. Advanced dementia is characterised by profound cognitive impairment, inability to communicate verbally and complete functional dependence. Usual care of people with advanced dementia is not underpinned universally by a palliative approach. Palliative care has focused traditionally on care of people with cancer but for more than a decade, there have been increased calls worldwide to extend palliative care services to include all people with life-limiting illnesses in need of specialist care, including people with dementia...

REVIEW
Gerd Flodgren, Daniela C Gonçalves-Bradley, Marie-Pascale Pomey
BACKGROUND: Inspection systems are used in healthcare to promote quality improvements (i.e. to achieve changes in organisational structures or processes, healthcare provider behaviour and patient outcomes). These systems are based on the assumption that externally promoted adherence to evidence-based standards (through inspection/assessment) will result in higher quality of healthcare. However, the benefits of external inspection in terms of organisational-, provider- and patient-level outcomes are not clear...

OBJECTIVE The median postoperative survival duration of patients with brain metastases who undergo tumor resection is 12 months. Most of these patients die of systemic metastases or the progression of primary cancer but not brain metastases. The criteria for indicating resection are still controversial. Systemic assessment is restricted, especially in patients who need emergent management for their large-size or life-threatening brain metastases. The neutrophil-to-lymphocyte ratio (NLR) is reported to correlate with survival time or progression-free survival in patients with various cancers...

A series of linear and trigonal copper(I) complexes bearing a cyclic alkyl(amino)carbene (CAAC) ligand show surprising photophysical properties when compared to their corresponding N-heterocyclic carbene (NHC) complexes. Whereas the linear NHC complexes [CuX(NHC)] are nearly non-emissive, [CuX(CAAC)] (X = Cl, Br, I) and [Cu(CAAC)2]PF6 show very bright emission from their triplet excited states in the blue to green region displaying quantum yields of up to 65% in the solid state, although the π-acceptor comprises only the carbene C and N atoms with no other π conjugation...

Hu Li, Zhen Fang, Jian He, Song Yang
The development of functional metal-organic materials being robust and active for bifunctional/cascade catalysis is of great significance. Herein, a series of mesoporous and orderly layered nanohybrids were synthesized for the first time via simple and template-free assembly of ortho-, meta-, or para-xylylenediphosphonates (o-, p-, or m-PhP) with zirconium. It was found that m-PhPZr nanoparticles (20-50 nm) with mesopores centered at 7.9 nm and high Lewis acid/base site ratio (1:0.7) showed prominent performance under mild conditions (as low as 82 ºC) in transfer hydrogenation of carbonyl compounds including bio-aldehydes to alcohols with near quantative yields and little Zr leaching...

Compressive sensing (CS) is a technique to sample a sparse signal below the Nyquist-Shannon limit, yet still enabling its reconstruction. As such, CS permits an extremely parsimonious way to store and transmit large and important classes of signals and images that would be far more data intensive should they be sampled following the prescription of the Nyquist-Shannon theorem. CS has found applications as diverse as seismology and biomedical imaging. In this work, we use actual optical signals generated from temporal intensity chaos from external-cavity semiconductor lasers (ECSL) to construct the sensing matrix that is employed to compress a sparse signal...

The high-pressure silicate K1.5Mg2Si2O7H0.5, synthesized and characterized by Welch et al. [(2012), Am. Mineral. 97, 1849-1857], has been re-examined with the aim of determining the nature of the superstructure noted in their study. The composition corresponds to a 1:1 combination of KMg2Si2O7H and K2Mg2Si2O7 end-members, but it is not a solid solution. Single-crystal X-ray diffraction data for one of the original K1.5Mg2Si2O7H0.5 crystals synthesized at 16 GPa/1573 K, has been collected using a much longer exposure time in order to improve the intensity statistics of weak superlattice reflections identified by Welch et al...

A new resistive bolometer system has been developed for MAST-Upgrade. It will measure radiated power in the new Super-X divertor, with millisecond time resolution, along 16 vertical and 16 horizontal lines of sight. The system uses a Xilinx Zynq-7000 series Field-Programmable Gate Array (FPGA) in the D-TACQ ACQ2106 carrier to perform real time data acquisition and signal processing. The FPGA enables AC-synchronous detection using high performance digital filtering to achieve a high signal-to-noise ratio and will be able to output processed data in real time with millisecond latency...

BACKGROUND: As in contact allergy, T cell-mediated hypersensitivity in non-immediate (NI) cutaneous adverse drug reactions (CADRs) to antibiotics is considered to be lifelong, but, in this setting, patch tests have rarely been repeated after long time intervals. OBJECTIVE: To evaluate the long-term reproducibility of positive patch test reactions to antibiotics in patients with NI CADRs. METHODS: Fifty-six patients with NI CADRs to antibiotics who had relevant positive reactions during patch testing were invited to repeat patch tests with a similar antibiotic series 2-15 years thereafter...

AIMS: Extendible endoprostheses have been available for more than 30 years and have become more sophisticated with time. The latest generation is 'non-invasive' and can be lengthened with an external magnetic force. Early results have shown a worryingly high rate of complications such as infection. This study investigates the incidence of complications and the need for further surgery in a cohort of patients with a non-invasive growing endoprosthesis. PATIENTS AND METHODS: Between 2003 and June 2014, 50 children (51 prostheses) had a non-invasive growing prosthesis implanted for a primary bone sarcoma...

AIMS: Femoral impaction bone grafting was first developed in 1987 using morselised cancellous bone graft impacted into the femoral canal in combination with a cemented, tapered, polished stem. We describe the evolution of this technique and instrumentation since that time. PATIENTS AND METHODS: Between 1987 and 2005, 705 revision total hip arthroplasties (56 bilateral) were performed with femoral impaction grafting using a cemented femoral stem. All surviving patients were prospectively followed for a mean of 14...

BACKGROUND: Hallux rigidus is the most common arthritic condition of the foot. A randomized clinical trial of first metatarsophalangeal (MTP) joint hemiarthroplasty with a polyvinyl alcohol (PVA) hydrogel implant (Cartiva) demonstrated pain relief and functional outcomes equivalent to first MTP arthrodesis at 2 years postoperation, with no cases of implant fragmentation, wear, or bone loss. We prospectively determined 5-year outcomes of first MTP hemiarthroplasty with the PVA hydrogel implant...

Radical cystectomy and regional lymph node dissection is the standard treatment for localized muscle-invasive and for high-risk non-muscle-invasive bladder cancer, and represents one of the main surgical urologic procedures. The open surgical approach is still widely adopted, even if in the last two decades efforts have been made in order to evaluate if minimally invasive procedures, either laparoscopic or robot-assisted, might show a benefit compared to the standard technique. Open radical cystectomy is associated with a high complication rate, but data from the laparoscopic and robotic surgical series failed to demonstrate a clear reduction in post-operative complication rates compared to the open surgical series...
