Around a quarter of hospital beds in the UK are occupied by patients living with dementia (PWD), and communication impairments are common across all types of dementia, often exacerbated by the hospital environment. Unsurprisingly, healthcare professionals (HCPs) report particular challenges in caring for this patient group, whilst trying to recognise and value their personhood as per the underpinning ethos of person-centred care. However, whilst there is a growing body of research that underlines the importance of communication in dementia care, there is far less that actually examines this communication in real time interaction...

OBJECTIVE: No method of grading visual field (VF) defects has been widely accepted throughout the glaucoma community. The SCHEIE (Systematic Classification of Humphrey visual fields-Easy Interpretation and Evaluation) grading system for glaucomatous visual fields was created to convey qualitative and quantitative information regarding visual field defects in an objective, reproducible, and easily applicable manner for research purposes. METHODS: The SCHEIE grading system is composed of a qualitative and quantitative score...

The objective of this experiment was to establish the effect of low-concentrate (LC) and high-concentrate (HC) supplementation in the early and late periods of lactation on milk production and cow traffic in a pasture-based automatic milking (AM) system. In total, 40 cows (10 primiparous and 30 multiparous) were randomly assigned to one of the two treatments. The experimental periods for the early and late lactation trials extended from 23 February to 12 April 2015 and 31 August to 18 October 2015, respectively (49 days in each trial period)...

The initial rational design, synthesis and validation of polymer-supported siloxane transfer agents have been achieved that permit the direct use of organolithium reagents in the palladium-catalyzed cross-coupling reactions. Through rational design, two generations of polymer support were developed that significantly simplify product purification and the transfer agent recycling.

Dietary risk assessment (DRA) of pesticides includes the estimation of chronic and acute exposures from crop residues, but assesses acute exposures only for pesticides with an acute reference dose (ARfD). Acute estimation uses high percentiles of food consumption surveys which are considerably higher than per capita lifetime averaged food consumption values which are used for chronic estimations. Assessing acute risks only for pesticides with an ARfD tacitly assumes that chronic risk assessment covers also intermittent occurring exposures which could significantly exceed chronic estimates...

PURPOSE: Previous work in Ontario demonstrated that 33% of patients with cancer with severe pain did not receive opioids at the time of their pain assessment. With efforts to increase symptom screening and management since then, the objective of this study was to examine temporal trends in opioid prescribing. METHODS: The cohort was comprised of Ontario residents ≥ 65 years of age with a cancer history who were eligible for the government pharmacare program and had a pain assessment using the Edmonton Symptom Assessment System...

Chromosome instability (CIN) is widely observed in both sporadic and hereditary colorectal cancer (CRC). Defects in APC and WNT signaling are primarily associated with CIN in hereditary CRC, but the genetic causes for CIN in sporadic CRC remain elusive. Using high-density SNP array and exome data from The Cancer Genome Atlas, we characterized loss of heterozygosity (LOH) and copy number variation (CNV) in the peripheral blood, normal colon and corresponding tumor tissue in 15 CRC patients with proficient mismatch repair (MMR) and 24 CRC patients with deficient MMR...

Minimal residual disease negative complete response (MRD-negative CR) provides an early marker for time to treatment failure (TTF) in CLL treated with fludarabine, cyclophosphamide, and rituximab (FCR). MRD was assessed after four FCR cycles (FCR4); MRD-negative CR patients discontinued treatment. Fifty-two patients (35M; 17F) were enrolled. Eighteen (18/52; 34.6%) patients reached MRD-negative CR after FCR4 and 29/52 (55.8%) were MRD-negative CR at end of treatment (EOT). Median TTF was 71.1 months (95% CI 61...

To advance magnetic resonance imaging (MRI) technologies further for in vivo tissue characterization with histopathologic validation, we investigated the feasibility of ex vivo tissue imaging of a surgically removed human brain tumor as a comprehensive approach for radiology-pathology correlation in histoanatomically identical fashion in a rare case of pigmented ganglioglioma with complex paramagnetic properties. Pieces of surgically removed ganglioglioma, containing melanin and hemosiderin pigments, were imaged with a small bore 7-T MRI scanner to obtain T1-, T2-, and T2*-weighted image and diffusion tensor imaging (DTI)...

AMP-activated protein kinase (AMPK) is a metabolic stress-sensing enzyme responsible for maintaining cellular energy homeostasis. Activation of AMPK by salicylate and the thienopyridone A-769662 is critically dependent on phosphorylation of Ser108 in the β1 regulatory subunit. Here, we show a possible role for Ser108 phosphorylation in cell cycle regulation and promotion of pro-survival pathways in response to energy stress. We identify the autophagy initiator Unc-51-like kinase 1 (ULK1) as a β1-Ser108 kinase in cells...

BACKGROUND: Pregnant women with type 1 diabetes are a high-risk population who are recommended to strive for optimal glucose control, but neonatal outcomes attributed to maternal hyperglycaemia remain suboptimal. Our aim was to examine the effectiveness of continuous glucose monitoring (CGM) on maternal glucose control and obstetric and neonatal health outcomes. METHODS: In this multicentre, open-label, randomised controlled trial, we recruited women aged 18-40 years with type 1 diabetes for a minimum of 12 months who were receiving intensive insulin therapy...

INTRODUCTION: Fractures of the scaphoid account for the most commonly injured carpal bone. Minimally displaced fractures of the waist will heal in 85-90% when using a below elbow cast. However, fractures with displacement have a higher risk for nonunion. Therefore, open reduction and fixation with headless compression screws (HCS) have become the preferred method of treatment. The aim of this study was to compare the radiological and clinical outcome of unstable scaphoid B2 type fractures, stabilized using one or two headless compression screws...

Activated natural killer (NK) cells engage in a robust metabolic response that is required for normal effector function. Using genetic, pharmacological and metabolic analyses, we demonstrated an essential role for Srebp transcription factors in cytokine-induced metabolic reprogramming of NK cells that was independent of their conventional role in the control of lipid synthesis. Srebp was required for elevated glycolysis and oxidative phosphorylation and promoted a distinct metabolic pathway configuration in which glucose was metabolized to cytosolic citrate via the citrate-malate shuttle...

Brain metastasis is a common complication in advanced systemic cancer, with an increasing incidence. The diagnosis of brain metastasis historically portended a dismal prognosis. The successful development of effective treatments for patients with brain metastasis is complicated by the differences among cancer subtypes, the limited understanding of the underlying pathophysiology of BM, the impact of the blood-brain barrier, and other factors. There is now renewed interest in treating this often devastating complication of cancer, and in understanding the underlying mechanisms of disease in this "sanctuary" site...

Bacterial meningitis and viral encephalitis, particularly herpes simplex encephalitis, are severe neurological infections that, if not treated promptly and effectively, lead to poor neurological outcome or death. Because of the value of early recognition and treatment, meningitis and encephalitis was chosen as an Emergency Neurological Life Support protocol. This protocol provides a practical approach to recognition and urgent treatment of bacterial meningitis and encephalitis. Appropriate imaging, spinal fluid analysis, and early empiric treatment are discussed...

Despite the growing international innovations for visual arts interventions in dementia care, limited attention has been paid to their theoretical basis. In response, this paper explores how and why visual art interventions in dementia care influence changes in outcomes. The theory building process consists of a realist review of primary research on visual art programmes. This aims to uncover what works, for whom, how, why and in what circumstances. We undertook a qualitative exploration of stakeholder perspectives of art programmes, and then synthesised these two pieces of work alongside broader theory to produce a conceptual framework for intervention development, further research and practice...
