Validation of the self-reported hearing questions in the Irish Longitudinal Study on Ageing against the Whispered Voice Test

BACKGROUND: Self report questions are often used in population studies to assess sensory efficacy and decline. These questions differ in their validity in assessing sensory impairment depending on the wording of the question and the characteristics of the population. We tested the validity of the self-report questions on hearing efficacy (self reported hearing, ability in following a conversation, use of a telephone and use of hearing aids) used in The Irish Longitudinal Study on Ageing (TILDA). METHODS: We tested sensitivity and specificity, positive and negative predictive values of each question against the Whispered Voice Test, a relatively easy to administer and cost effective alternative to the standard audiometric test. RESULTS: In this population the question ‘Is your hearing (with or without a hearing appliance)/ Excellent/Very Good/Good/Fair/Poor?’ showed the best diagnostic value in relation to the other questions (sensitivity 55.56% and specificity 94.67%). The question ‘Can you use a normal telephone?’ was deemed ineffective because of a very poor sensitivity (5.56%) and was proposed for exclusion from subsequent waves of TILDA. CONCLUSIONS: We showed that this validity check was useful to select the questions that most effectively assess hearing deficits and provided crucial information for the subsequent waves. We argue that longitudinal studies using self-reports of sensory efficacy would benefit from a similar check

Prevalence of age-related macular degeneration in the Republic of Ireland

Abstract Background Age-related macular degeneration (AMD) remains the most common cause of visual loss among subjects over 50 years of age in the developed world. The Irish Longitudinal study on Ageing (TILDA) is a population-based study of subjects aged 50 years or older, designed to investigate factors that influence ageing, and has enabled this investigation of the prevalence of AMD in the Republic of Ireland (ROI). Methods Data collected from a nationally representative sample of community-living older adults aged 50 years and over in ROI over the period November 2009 to July 2011. 5035 participants attended the TILDA health centre for assessment. Retinal photographs were obtained in 4859 of these participants. Retinal grading was performed in a masked fashion using a modified version of the International Classification and Grading System for AMD. Results Adjusting for lower response rates among older subjects, the estimated overall prevalence of any AMD was 7.2% (95% CI 6.5% to 7.9%) in the population aged 50 years or older. The estimated prevalence of early AMD was 6.6% (95% CI 5.9% to 7.3%), and the estimated prevalence of late AMD was 0.6% (95% CI 0.4% to 0.8%). Statistically significant associations with AMD included increasing age and family history of the condition. Conclusions This is the first study to provide prevalence estimates of AMD in ROI and will inform eye care professionals and policymakers involved in the delivery and planning of care for those afflicted with this condition

The role of atmosphere feedbacks during ENSO in the CMIP3 models. Part III: the shortwave flux feedback

Previous studies using coupled general circulation models (GCMs) suggest that the atmosphere model plays a dominant role in the modeled El Nin ̃ o–Southern Oscillation (ENSO), and that intermodel differences in the thermodynamical damping of sea surface temperatures (SSTs) are a dominant contributor to the ENSO amplitude diversity. This study presents a detailed analysis of the shortwave flux feedback (aSW) in 12 Coupled Model Intercomparison Project phase 3 (CMIP3) simulations, motivated by findings that aSW is the primary contributor to model thermodynamical damping errors. A ‘‘feedback decomposition method,’’ developed to elucidate the aSW biases, shows that all models un- derestimate the dynamical atmospheric response to SSTs in the eastern equatorial Pacific, leading to un- derestimated aSW values. Biases in the cloud response to dynamics and the shortwave interception by clouds also contribute to errors in aSW. Changes in the aSW feedback between the coupled and corresponding atmosphere-only simulations are related to changes in the mean dynamics. A large nonlinearity is found in the observed and modeled SW flux feedback, hidden when linearly cal- culating aSW. In the observations, two physical mechanisms are proposed to explain this nonlinearity: 1) a weaker subsidence response to cold SST anomalies than the ascent response to warm SST anomalies and 2) a nonlinear high-level cloud cover response to SST. The shortwave flux feedback nonlinearity tends to be underestimated by the models, linked to an underestimated nonlinearity in the dynamical response to SST. The process-based methodology presented in this study may help to correct model ENSO atmospheric biases, ultimately leading to an improved simulation of ENSO in GCMs

Professionalisms at war? Interpreting in conflict and post-conflict situations

This article examines the ways in which the situational and institutional contexts of interpreting in war and in post-conflict development bring interpreting into close proximity with alternative and dominant forms of professionalism which serve to condition the work and status of the interpreters involved. By drawing on evidence from conflict situations, the professional interpreting association AIIC, and research interviews, the article questions traditional notions of what constitutes the ‘profession’ of interpreting. It argues that in the context of war, military professionalism has tended to allow little space for key tenets of professional interpreting, but that recent conflicts have led to an interrogation of how such competing professionalisms might begin to coexist. In post-conflict development, on the other hand, the traditional models of ‘development professionals’ have largely concealed the role of language mediation, and this relative invisibility has meant that a similar interrogation on competing professionalisms has yet to take place

Transitioning to home and beyond following stroke: a prospective cohort study of outcomes and needs

Introduction: Understanding of the needs of people with stroke at hospital discharge and in the first six-months is limited. This study aim was to profile and document the needs of people with stroke at hospital discharge to home and thereafter. Methods: A prospective cohort study recruiting individuals with stroke, from three hospitals, who transitioned home, either directly, through rehabilitation, or with early supported discharge teams. Their outcomes (global-health, cognition, function, quality of life, needs) were described using validated questionnaires and a needs survey, at 7–10 days, and at 3-, and 6-months, post-discharge. Results: 72 patients were available at hospital discharge; mean age 70 (SD 13); 61% female; median NIHSS score of 4 (IQR 0–20). 62 (86%), 54 (75%), and 45 (63%) individuals were available respectively at each data collection time-point. Perceived disability was considerable at hospital discharge (51% with mRS ≥ 3), and while it improved at 3-months, it increased thereafter (35% with mRS ≥ 3 at 6-months). Mean physical health and social functioning were “fair” at hospital discharge and ongoing; while HR-QOL, although improved over time, remained impaired at 6-months (0.69+/-0.28). At 6-months cognitive impairment was present in 40%. Unmet needs included involvement in transition planning and care decisions, with ongoing rehabilitation, information, and support needs. The median number of unmet needs at discharge to home was four (range:1–9), and three (range:1–7) at 6-months. Conclusion: Stroke community reintegration is challenging for people with stroke and their families, with high levels of unmet need. Profiling outcomes and unmet needs for people with stroke at hospital-to-home transition and onwards are crucial for shaping the development of effective support interventions to be delivered at this juncture

Global perspectives on observing ocean boundary current systems. Frontiers in Marine Science, 6, (2010); 423, doi: 10.3389/fmars.2019.00423.Ocean boundary current systems are key components of the climate system, are home to highly productive ecosystems, and have numerous societal impacts. Establishment of a global network of boundary current observing systems is a critical part of ongoing development of the Global Ocean Observing System. The characteristics of boundary current systems are reviewed, focusing on scientific and societal motivations for sustained observing. Techniques currently used to observe boundary current systems are reviewed, followed by a census of the current state of boundary current observing systems globally. The next steps in the development of boundary current observing systems are considered, leading to several specific recommendations.RT was supported by The Andrew W.

The international WAO/EAACI guideline for the management of hereditary angioedema – the 2017 revision and update

Abstract Hereditary Angioedema (HAE) is a rare and disabling disease. Early diagnosis and appropriate therapy are essential. This update and revision of the global guideline for HAE provides up-to-date consensus recommendations for the management of HAE. In the development of this update and revision of the guideline, an international expert panel reviewed the existing evidence and developed 20 recommendations that were discussed, finalized and consented during the guideline consensus conference in June 2016 in Vienna. The final version of this update and revision of the guideline incorporates the contributions of a board of expert reviewers and the endorsing societies. The goal of this guideline update and revision is to provide clinicians and their patients with guidance that will assist them in making rational decisions in the management of HAE with deficient C1-inhibitor (type 1) and HAE with dysfunctional C1-inhibitor (type 2). The key clinical questions covered by these recommendations are: 1) How should HAE-1/2 be defined and classified?, 2) How should HAE-1/2 be diagnosed?, 3) Should HAE-1/2 patients receive prophylactic and/or on-demand treatment and what treatment options should be used?, 4) Should HAE-1/2 management be different for special HAE-1/2 patient groups such as pregnant/lactating women or children?, and 5) Should HAE-1/2 management incorporate self-administration of therapies and patient support measures?

Sport, peacemaking and conflict resolution: a contextual analysis and modelling of the sport, development and peace sector

International audienceIn recent years, a wide variety of organizations (notably the UN and nongovernmental ones) have used sport as an interventionist tool to nurture peacemaking across divided communities. This paper examines and theorizes these peacemaking initiatives across the expanding 'sport, development and peace' (SDP) sector. I begin by locating SDP projects within their historical contexts, and as significant elements within the emerging 'global civil society'. I then set out three ideal-type models of SDP project; namely, the 'technical', 'dialogical', and 'critical'. Each model is examined through a set of common social heuristics, such as its core objectives and paradigmatic methods. The models may be employed to analyze other peacemaking and development fields. The first two models are most influential among existing SDP projects; the potential benefits of the 'critical' model are also outlined

Home and Online Management and Evaluation of Blood Pressure (HOME BP) using a digital intervention in poorly controlled hypertension: randomised controlled trial

Objective: The HOME BP (Home and Online Management and Evaluation of Blood Pressure) trial aimed to test a digital intervention for hypertension management in primary care by combining self-monitoring of blood pressure with guided self-management. Design: Unmasked randomised controlled trial with automated ascertainment of primary endpoint. Setting: 76 general practices in the United Kingdom. Participants: 622 people with treated but poorly controlled hypertension (>140/90 mm Hg) and access to the internet. Interventions: Participants were randomised by using a minimisation algorithm to self-monitoring of blood pressure with a digital intervention (305 participants) or usual care (routine hypertension care, with appointments and drug changes made at the discretion of the general practitioner; 317 participants). The digital intervention provided feedback of blood pressure results to patients and professionals with optional lifestyle advice and motivational support. Target blood pressure for hypertension, diabetes, and people aged 80 or older followed UK national guidelines. Main outcome measures: The primary outcome was the difference in systolic blood pressure (mean of second and third readings) after one year, adjusted for baseline blood pressure, blood pressure target, age, and practice, with multiple imputation for missing values. Results: After one year, data were available from 552 participants (88.6%) with imputation for the remaining 70 participants (11.4%). Mean blood pressure dropped from 151.7/86.4 to 138.4/80.2 mm Hg in the intervention group and from 151.6/85.3 to 141.8/79.8 mm Hg in the usual care group, giving a mean difference in systolic blood pressure of −3.4 mm Hg (95% confidence interval −6.1 to −0.8 mm Hg) and a mean difference in diastolic blood pressure of −0.5 mm Hg (−1.9 to 0.9 mm Hg). Results were comparable in the complete case analysis and adverse effects were similar between groups. Within trial costs showed an incremental cost effectiveness ratio of £11 ($15, €12; 95% confidence interval £6 to £29) per mm Hg reduction. Conclusions: The HOME BP digital intervention for the management of hypertension by using self-monitored blood pressure led to better control of systolic blood pressure after one year than usual care, with low incremental costs. Implementation in primary care will require integration into clinical workflows and consideration of people who are digitally excluded. Trial registration: ISRCTN13790648
