Sedative load of medications prescribed for older people with dementia in care homes

The objective of this study was to determine the sedative load and use of sedative and psychotropic medications among older people with dementia living in (residential) care homes.

A CFTR Potentiator in Patients with Cystic Fibrosis and the G551D Mutation

Background:

Increasing the activity of defective cystic fibrosis transmembrane conductance regulator (CFTR) protein is a potential treatment for cystic fibrosis.

Methods:

We conducted a randomized, double-blind, placebo-controlled trial to evaluate ivacaftor (VX-770), a CFTR potentiator, in subjects 12 years of age or older with cystic fibrosis and at least one G551D-CFTR mutation. Subjects were randomly assigned to receive 150 mg of ivacaftor every 12 hours (84 subjects, of whom 83 received at least one dose) or placebo (83, of whom 78 received at least one dose) for 48 weeks. The primary end point was the estimated mean change from baseline through week 24 in the percent of predicted forced expiratory volume in 1 second (FEV1).

Results:

The change from baseline through week 24 in the percent of predicted FEV1 was greater by 10.6 percentage points in the ivacaftor group than in the placebo group (P < 0.001). Effects on pulmonary function were noted by 2 weeks, and a significant treatment effect was maintained through week 48. Subjects receiving ivacaftor were 55% less likely to have a pulmonary exacerbation than were patients receiving placebo, through week 48 (P < 0.001). In addition, through week 48, subjects in the ivacaftor group scored 8.6 points higher than did subjects in the placebo group on the respiratory-symptoms domain of the Cystic Fibrosis Questionnaire-revised instrument (a 100-point scale, with higher numbers indicating a lower effect of symptoms on the patient's quality of life) (P < 0.001). By 48 weeks, patients treated with ivacaftor had gained, on average, 2.7 kg more weight than had patients receiving placebo (P < 0.001). The change from baseline through week 48 in the concentration of sweat chloride, a measure of CFTR activity, with ivacaftor as compared with placebo was -48.1 mmol per liter (P < 0.001). The incidence of adverse events was similar with ivacaftor and placebo, with a lower proportion of serious adverse events with ivacaftor than with placebo (24% vs. 42%).

Conclusions:

Ivacaftor was associated with improvements in lung function at 2 weeks that were sustained through 48 weeks. Substantial improvements were also observed in the risk of pulmonary exacerbations, patient-reported respiratory symptoms, weight, and concentration of sweat chloride.

A simple method for assessing copper-mediated oxidation of very-low-density lipoprotein isolated by rapid ultracentrifugation

The association of very-low-density lipoprotein (VLDL) with atherosclerosis remains controversial. However, studies have shown that oxidative modification of VLDL can promote foam cell formation, leading to the development of atherosclerosis. A rapid method is described which will allow the significance of VLDL oxidation to be assessed in clinical studies. VLDL was isolated from heparinized plasma by a 1-h, single spin ultracentrifugation. Total protein was standardized to 25 mg/L. Oxidation was promoted by the addition of copper ions (17.5 mu mol/L, final concentration) incubated at 37 degrees C. Conjugated diene production was followed at 234 nm. Total assay preparation time was 2 h. Urate greatly inhibited the oxidation of VLDL and was successfully removed by size exclusion chromatography. VLDL isolated from frozen plasma (-70 degrees C) was stable for 15 weeks. This simple, rapid method for the isolation of VLDL may be applied to assess the significance of VLDL oxidation in disease.

Susceptibility of VLDL to oxidation in patients on regular haemodialysis

Oxidation of VLDL in vitro increases macrophage uptake and promotes foam cell formation, and the dyslipidaemia of chronic renal failure is characterised by an increase in VLDL. However, little information is available with regard to the susceptibility of VLDL to oxidation in patients at increased risk of atherosclerosis. We have therefore assessed the composition and susceptibility to oxidation of VLDL from haemodialysis patients anti control subjects. VLDL from haemodialysis patients contained increased lipid hydroperoxides (81.6 +/- 12.6 versus 16.1 +/- 3.4 nmol/mg protein, P

Romanticism and Blackwood's Magazine:'An Unprecedented Phenomenon'

Romanticism and Blackwood's Magazine is inspired by the ongoing critical fascination with Blackwood's Edinburgh Magazine, and the burgeoning recognition of its centrality to the Romantic age. Though the magazine itself was published continuously for well over a century and a half, this volume concentrates specifically on those years when William Blackwood was at the helm, beginning with his founding of the magazine in 1817 and closing with his death in 1834. These were the years when, as Samuel Taylor Coleridge put it in 1832, Blackwood's reigned as 'an unprecedented Phenomenon in the world of letters.' The magazine placed itself at the centre of the emerging mass media, commented decisively on all the major political and cultural issues that shaped the Romantic movement, and published some of the leading writers of the day, including Coleridge, Thomas De Quincey, John Galt, Felicia Hemans, James Hogg, Walter Scott, and Mary Shelley.

'This much-needed volume reminds us not only why Blackwood's was the most influential periodical publication of the time, but also how its writers, writings, and critical agendas continue to shape so many of the scholarly concerns of Romantic studies in the twenty-first century.' - Charles Mahoney, Associate Professor, University of Connecticut, USA

Seven new loci associated with age-related macular degeneration

Age-related macular degeneration (AMD) is a common cause of blindness in older individuals. To accelerate the understanding of AMD biology and help design new therapies, we executed a collaborative genome-wide association study, including >17,100 advanced AMD cases and >60,000 controls of European and Asian ancestry. We identified 19 loci associated at P <5 × 10(-8). These loci show enrichment for genes involved in the regulation of complement activity, lipid metabolism, extracellular matrix remodeling and angiogenesis. Our results include seven loci with associations reaching P <5 × 10(-8) for the first time, near the genes COL8A1-FILIP1L, IER3-DDR1, SLC16A8, TGFBR1, RAD51B, ADAMTS9 and B3GALTL. A genetic risk score combining SNP genotypes from all loci showed similar ability to distinguish cases and controls in all samples examined. Our findings provide new directions for biological, genetic and therapeutic studies of AMD.

Social Dance for Successful Aging:The Practice of Health, Happiness, and Social Inclusion Amongst Senior Citizens

This article presents findings from a qualitative study of social
dancing for successful aging amongst senior citizens in three locales:
in Blackpool (GB), around Belfast (NI), and in Sacramento (US). Social
dancers are found to navigate an intense space in society, one of
wellbeing accompanied by a beneficial sense of youthfulness. Besides
such renewal and self-actualisation, findings also attest to the perceived
social, psychological and health benefits of social dancing amongst senior
citizens. They also articulate three different social dancing practices:
social dance as tea dance (Sacramento), social dance as practice dance
(Blackpool), social dance as motility (Belfast and environs).

Reading Elizabeth Bishop's "Artifact of [Words]"

As Emerson noted in his essay 'The Poet' "we are not pans and barrows, not even porters of the fire and torch-bearers, but children of the fire, made of it, and only the same divinity transmuted, and at two or three removes, when we least know about it." For Emerson, the fire is poetry, an elemental force capable of transmutation, transformation and enduring relevance. Moving from Emerson, Elizabeth Bishop rises as the twentieth-century poet most aligned with the possibility of poetry and the powers of its practice, as 'At The Fishhouses' indicates in her clear referencing of Emerson:

"If you should dip your hand in,
your wrist would ache immediately,
your bones would begin to ache and your hand would burn
as if the water were a transmutation of fire
that feeds on stones and burns with a dark gray flame."

This essay will look in detail at Bishop's understanding of the possibility of poetry and how art functions as a multi-dimensional structure that is unsettled as much as it unsettles. In particular, Bishop's poem 'The Monument' will be unpicked as testament both to the practice of Bishop's art and also the role of the poet critic responding to what they uncover
