IPH response to Department of Health (ROI) consultation on National Strategy on Dementia

The current prevalence of dementia and its associated economic and social burden presents a challenge for the configuration of dementia care services at present and it is clear that this challenge will become ever more urgent as a consequence of population ageing. IPH supports the development of a Dementia Strategy in Ireland that is comprehensive and holistic. We recommend that the strategy encompasses aspects of prevention as well as optimal management at all stages of the disease. IPH considers that a social determinants of health approach that focuses on the prevention of disease and disability could form an important strand of the strategy. Key points from IPH response IPH would emphasise the following key priorities for inclusion in the Dementia Strategy.   Adoption of a public health approach as set out by WHO (2011) and the development of an implementation plan and structures to support the Strategy A commitment to primary, secondary and tertiary prevention of dementia.  Resourcing of a programme of research to support primary, secondary and tertiary prevention of dementia to ensure a systematic approach to generate an evidence-base and disseminate pertinent findings in the Irish context. Emphasis should be placed on high quality research specifically to:enhance information systems on dementia at a national level A life course approach to tackle the social determinants of dementia and ill-health in later life.

BGS response to the Health Foundation Improvement Report on Dementia Care

Dementia services have moved up the agenda in recent years, highlighted by the publication of the National Dementia Strategy in February 2009. The Health Foundation's improvement report on dementia care hopes to bring together data, research and good practice, with an assessment of the current quality gap.Background to The Health Foundation's Improvement Reports in 2010. At the end of 2009 the Health Foundation agreed a new research and development strategy with the following aims:To make a significant contribution to strengthening the evidence base on how to improve quality in the health care systems of the UK To ensure that this body of knowledge, and a commitment to developing the knowledge shapes our work programmes To promote the use of this evidence base by decision makers at all levels in the health care system Improvement reports will aim to engage the reader by presenting best practice evidence alongside data on current performance and introducing commentary and debate, interpretation about possible next steps and case studies.�� They will build on the success of the chart books produced to date: Bridging the Quality Gap in Stroke services�۪ Quality in healthcare in England, Wales, Scotland, Northern Ireland: an intra-UK chart book�۪, together with Bridging the Quality Gap in Heart Failure�۪ to be published early 2010. Improvement reports will be dynamic and flexible through use of a mix of print products and pages on the Health Foundation�۪s website.

Evaluation of professional knowledge and attitudes on dementia patient care: a trans-cultural adaptation of an evaluation instrument

Objective To describe the trans-cultural adaptation of the evaluation instrument entitled Atenció Sanitària de Les Demències: la visió de L' Atenció Primarià from Catalan into versions in Portuguese for doctors and nurses. This study evaluates the knowledge and perspectives of these professionals in their treatment of patients diagnosed with dementia in cases of primary care. Method The adaptation followed internationally accepted rules, which include the following steps: translation, synthesis, back-translation, revision by a committee of specialists, and a test run with 35 practicing doctors and 35 practicing nurses in Brazil's Family Health Strategy (Estratégia Saúde da Família, or ESF in Portuguese). Results The translation, synthesis, and back-translation steps were performed satisfactorily; only small adjustments were required. The committee of specialists verified the face validity in the version translated into Portuguese, and all of the items that received an agreement score lower than 80% during the initial evaluation were revised. In the test run, the difficulties presented by the health care professionals did not reach 15% of the sample, and therefore, no changes were made. Conclusion The Portuguese translation of the instrument can be considered semantically, idiomatically, culturally, and conceptually equivalent to the original Catalan version and is, therefore, appropriate for use in Brazil.

Effect of exercise training on preeclampsia superimposed on chronic hypertension in a mouse model

Preeclampsia is among the leading causes of perinatal mortality and morbidity, affecting 2-7% of pregnancies. Its incidence increases to 10-25% in already hypertensive women. To date, no treatment, aside from delivery, is known. Interestingly, several studies have reported that exercise training (ExT) can reduce preeclampsia prevalence although the available studies are considered insufficient. Therefore, the aim of this study is to determine the impact of ExT when practiced before and during gestation on pregnancy outcome in a mouse model of preeclampsia superimposed on chronic hypertension (SPE). To do so, mice overexpressing both human angiotensinogen and renin (R+A+) were used because they are hypertensive at baseline and they develop many hallmark features of SPE. Mice were trained by placing them in a cage with access to a running wheel 4 weeks before and during gestation. ExT in this study prevented the rise in blood pressure at term observed in the sedentary transgenic mothers. This may be realized through an increased activity of the angiotensin-(1-7) axis in the aorta. In addition, ExT prevented the increase in albumin/creatinine ratio. Moreover, placental alterations were prevented with training in transgenic mice, leading to improvements in placental and fetal development. Placental mRNA and circulating levels of sFlt-1 were normalized with training. Additionally, the increase in angiotensin II type I receptor and the decrease in Mas receptor protein were reversed with training. ExT appears to prevent many SPE-like features that develop in this animal model and may be of use in the prevention of preeclampsia in women.

Du delirium au syndrome démentiel: prise en charge médicamenteuse dans les EMS fribourgeois [Management of elderly patients with delirium or dementia in Swiss nursing homes].

Management of elderly patients with delirium or dementia in Swiss nursing homes Dementia and delirium are among the most frequent medical conditions in older nursing home residents. Their management require a coordinated interdisciplinary approach, including for drug prescription. Using a systematic literature review of published meta-analyses and guidelines, prescription algorithms were developed adressing the pharmacological management of cognitive symptoms of dementia and delirium in older nursing home residents in the canton of Fribourg.

On The Consistency Of Monte Carlo Track Structure Dna Damage Simulations.

Monte Carlo track structures (MCTS) simulations have been recognized as useful tools for radiobiological modeling. However, the authors noticed several issues regarding the consistency of reported data. Therefore, in this work, they analyze the impact of various user defined parameters on simulated direct DNA damage yields. In addition, they draw attention to discrepancies in published literature in DNA strand break (SB) yields and selected methodologies. The MCTS code Geant4-DNA was used to compare radial dose profiles in a nanometer-scale region of interest (ROI) for photon sources of varying sizes and energies. Then, electron tracks of 0.28 keV-220 keV were superimposed on a geometric DNA model composed of 2.7 × 10(6) nucleosomes, and SBs were simulated according to four definitions based on energy deposits or energy transfers in DNA strand targets compared to a threshold energy ETH. The SB frequencies and complexities in nucleosomes as a function of incident electron energies were obtained. SBs were classified into higher order clusters such as single and double strand breaks (SSBs and DSBs) based on inter-SB distances and on the number of affected strands. Comparisons of different nonuniform dose distributions lacking charged particle equilibrium may lead to erroneous conclusions regarding the effect of energy on relative biological effectiveness. The energy transfer-based SB definitions give similar SB yields as the one based on energy deposit when ETH ≈ 10.79 eV, but deviate significantly for higher ETH values. Between 30 and 40 nucleosomes/Gy show at least one SB in the ROI. The number of nucleosomes that present a complex damage pattern of more than 2 SBs and the degree of complexity of the damage in these nucleosomes diminish as the incident electron energy increases. DNA damage classification into SSB and DSB is highly dependent on the definitions of these higher order structures and their implementations. The authors' show that, for the four studied models, different yields are expected by up to 54% for SSBs and by up to 32% for DSBs, as a function of the incident electrons energy and of the models being compared. MCTS simulations allow to compare direct DNA damage types and complexities induced by ionizing radiation. However, simulation results depend to a large degree on user-defined parameters, definitions, and algorithms such as: DNA model, dose distribution, SB definition, and the DNA damage clustering algorithm. These interdependencies should be well controlled during the simulations and explicitly reported when comparing results to experiments or calculations.

Causes and consequences of long-term climatic variability on the Australian continent

1. Ice-volume forced glacial-interglacial cyclicity is the major cause of global climate variation within the late Quaternary period. Within the Australian region, this variation is expressed predominantly as oscillations in moisture availability. Glacial periods were substantially drier than today with restricted distribution of mesic plant communities, shallow or ephemeral water bodies and extensive aeolian dune activity. 2. Superimposed on this cyclicity in Australia is a trend towards drier and/or more variable climates within the last 350 000 years. This trend may have been initiated by changes in atmospheric and ocean circulation resulting from Australia's continued movement into the Southeast Asian region and involving the onset or intensification of the El Nino-Southern Oscillation system and a reduction in summer monsoon activity. 3. Increased biomass burning, stemming originally from increased climatic variability and later enhanced by activities of indigenous people, resulted in a more open and sclerophyllous vegetation, increased salinity and a further reduction in water availability. 4. Past records combined with recent observations suggest that the degree of environmental variability will increase and the drying trend will be enhanced in the foreseeable future, regardless of the extent or nature of human intervention.

An ESR study on gamma-irradiated poly(vinyl alcohol)

The formation of radicals in poly(vinyl alcohol), PVA, powder irradiated at 77 K by gamma -rays and the transformations of these radicals during photolysis with visible wavelengths and on thermal annealing have been studied. After irradiation a four-line ESR spectrum was observed. It was assigned to a triplet of the C-alpha-radical (38%), with a splitting of 3.27 mT, superimposed on a doublet (62%) with a splitting of 2.7 mT. The doublet appears to be composed of two radicals, one of which is photo-bleachable (58%) and the other which is not photo-bleachable (42%). This suggests that the latter radical is a neutral radical. The photo-bleachable component of the doublet has been assigned to a carbonyl anion radical. but the second doublet due to a neutral radical is unassigned. The total G-value for formation of radicals at 77 K was found to be 2.41 +/- 0.03. Upon illumination with visible light, the anion radicals were removed and the doublet components or the spectrum diminished in intensity, while the three-line spectrum of the C-alpha-radical became more clearly visible. This transition was due to the photo-detachment of electrons from traps which were proposed to be located on carbonyl groups in the polymer resulting from incomplete hydrolysis of the vinyl acetate. The photo-decay of the anion radicals could be satisfactorily described by a two-stage process. The first stage comprised the decay of approximately 80% of the anion radicals present, while the second stage was associated with the decay of the remaining 20%. Subsequent thermal annealing of a photolysed sample to 290 K led to a change in the shape of the spectrum to form a more clearly defined triplet, As the doublet of the neutral radical decays on thermal annealing between 150 and 250K, the C-alpha-radical is formed.

Obesity and central obesity as risk factors for incident dementia and its subtypes: a systematic review and meta-analysis

While dementia affects 6-10% of persons 65 years or older, industrialized countries have witnessed an alarming rise in obesity. However, obesity's influence on dementia remains poorly understood. The conducted a systematic review and meta-analysis. PUBMED search (1995-2007) resulted in 10 relevant prospective cohort studies of older adults (40-80 years at baseline) with end points being dementia and predictors including adiposity measures, such as body mass index (BMI) and waist circumference (WC). There was a significant U-shaped association between BMI and dementia (P= 0.034), with dementia risk increased for obesity and underweight. Pooled odds ratios (OR) and 95% confidence intervals (CI) for underweight, overweight and obesity compared with normal weight in relation to incident dementia were: 1.36 (1.07, 1.73), 0.88 (0.60, 1.27) and 1.42 (0.93, 2.18) respectively. Pooled ORs and 95% CI for obesity and incident Alzheimer's disease (AD) and vascular dementia were 1.80 (1.00, 3.29) vs. 1.73 (0.47, 6.31) and were stronger in studies with long follow-up (>10 years) and young baseline age (
