Background: Obesity is a driver of multimorbidity. Knowledge regarding individual and population based solutions is evolving in primary care. Stigma/self-stigma are important in developing clinical solutions. Inquiry based stress reduction (IBSR) is emerging as a solution for self-stigma in a range of conditions. This study explores IBSR (also known as The Work of Byron Katie) in obesity self-stigma in the GP setting, with severe obesity, utilising a multidisciplinary approach., Aim: Is it feasible/acceptable to utilise Inquiry Based Stress Reduction in the GP setting for obesity?, Method: Mixed-method pilot study including a convenience sample of people with severe spectrum obesity from a three-doctor general practice, including use of IBSR provided in both group, partner and individual settings, predominantly online, utilising certified and accredited IBSR facilitators, a clinical psychologist, and participating GPs. Outcomes include pre- and post-intervention surveys (Becks Depression Scale, HRQoL, Weight Bias Internalisation Scale, Weight Self-stigma Questionnaire) and qualitative data from participants., Results: Of 22 initially invited to participate, 14 commenced and 10 completed the intervention. Mean BMI was 42.8, mean age 49 years, female:male = 7:3. Many believed obesity was their own fault, related very difficult interactions with healthcare professionals, and valued opportunity to engage with the intervention. While participants had alarming levels of comorbidity, they were far more concerned regarding stigma and self-stigma., Conclusion: Results and experience in practice indicate this approach is feasible and acceptable. Results are valuable in planning a larger study in multiple practices., (© British Journal of General Practice 2024.)

During the pandemic, many older adults felt 'out of place' in their home, work, and community spaces with potentially long-term consequences for health and wellbeing. Using national data from the COVID-19 Coping Study, thematic analysis of online long-answer responses (n = 1171; mean age 68 years; 71% female; 93% non-Hispanic White; 86% with at least a 4-year college degree; data collected April-June 2022) identified four themes regarding why particular places are challenging since the pandemic onset: (1) viral exposure fears, (2) frustrating regulations, (3) uncomfortable and hostile social dynamics, and (4) 'out of place' negative emotions. Participants also shared how they continuously address or adapt to place-based challenges through lifestyle adjustments and coping strategies. Novel findings may inform multi-scalar policymaking and interventions to support wellbeing in later life in times of stress and instability., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Objectives: Identifying social policies that can promote cognitive health is crucial for reducing the global burden of dementia. We evaluated the importance of educational attainment for later-life cognitive function in various social and geographic settings., Methods: Using harmonized data for individuals aged ≥65 years from the United States Health and Retirement Study (HRS) and its international partner studies in England, Mexico, China, and India, and each study's respective Harmonized Cognitive Assessment Protocol (HCAP), we conducted a cross-national comparative study to examine the role of educational attainment in later-life cognitive function across countries (n = 14,980, 2016-2019). We used multivariable-adjusted regression to estimate associations between educational attainment and harmonized global cognitive function scores., Results: In Mexico, China, and India, the general cognitive function scores on average are approximately one standard deviation of the HRS-HCAP cognitive function score distribution lower compared to the United States and England, paralleling patterns of educational attainment across countries. In all countries, higher educational attainment was associated with progressively higher later-life cognitive function scores. Population-level differences in educational attainment explained about 50%-90% of the observed differences in cognitive function scores across countries., Discussion: The relationship between education and later-life cognitive function across social and geographic contexts underscores the crucial role of education to promote cognitive health and reduce dementia risk. Continual improvement of educational attainment in low- and middle-income settings may yield a significant pay-off in later-life cognitive health., (© The Author(s) 2024.

The direction of particle accelerator development is ever-increasing beam quality, currents and repetition rates. This poses a challenge to traditional diagnostics that directly intercept the beam due to the mutual destruction of both the beam and the diagnostic. An alternative approach is to infer beam parameters non-invasively from the synchrotron radiation emitted in bending magnets. However, inferring the beam distribution from a measured radiation pattern is a complex and computationally expensive task. To address this challenge we present SYRIPY (SYnchrotron Radiation In PYthon), a software package intended as a tool for performing inference of synchrotron-radiation-based diagnostics. SYRIPY has been developed using PyTorch, which makes it both differentiable and able to leverage the high performance of GPUs, two vital characteristics for performing statistical inference. The package consists of three modules: a particle tracker, Lienard-Wiechert solver and Fourier optics propagator, allowing start-to-end simulation of synchrotron radiation detection to be carried out. SYRIPY has been benchmarked against SRW, the prevalent numerical package in the field, showing good agreement and up to a 50× speed improvement. Finally, we have demonstrated how SYRIPY can be used to perform Bayesian inference of beam parameters using stochastic variational inference., (open access.)

Introduction: We conducted a cross-national comparison of the association between main lifetime occupational skills and later-life cognitive function across four economically and socially distinct countries., Methods: Data were from population-based studies of aging and their Harmonized Cognitive Assessment Protocols (HCAPs) in the US, South Africa, India, and Mexico (N = 10,037; Age range: 50 to 105 years; 2016 to 2020). Main lifetime occupational skill was classified according to the International Standard Classification of Occupations. Weighted, adjusted regression models estimated pooled and country-specific associations between main lifetime occupational skill and later-life general cognitive function in men and women., Results: We observed positive gradients between occupational skill and later-life cognitive function for men and women in the US and Mexico, a positive gradient for women but not men in India, and no association for men or women in South Africa., Discussion: Main lifetime occupations may be a source of later-life cognitive reserve, with cross-national heterogeneity in this association., Highlights: No studies have examined cross-national differences in the association of occupational skill with cognition. We used data from Harmonized Cognitive Assessment Protocols in the US, Mexico, India, and South Africa. The association of occupational skill with cognitive function varies by country and gender., (© 2023 The Authors.

Little is known about longer-term changes to community participation since the COVID-19 pandemic onset and potential implications for health and wellbeing in later life. This multi-method investigation analyzes national data from the COVID-19 Coping Study. Statistical analyses of survey data ( n = 1,630; mean age 67.9 years; data collected April/May 2022) identified that adults residing in the US still tended to stay inside their homes more often since the pandemic onset. Overall, participants decreased their engagement with amenities such as eateries, gyms, and arts and cultural sites. Reflexive thematic analysis of semi-structured in-depth interviews ( n = 57; mean age 70.7 years; data collected May-July 2021) identified altered community participation with perceived long-term impacts on physical, mental, and social health and wellbeing. The results provide novel insights about the critical nature of 'third places' to support later life, and policy implications to strengthen community environments. Investment in outdoor, well-ventilated, and distanced third places may support wellbeing., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Background: Hyponatremia and hypernatremia, as conventionally defined (<135 mEq/L and >145 mEq/L, respectively), are associated with increased perioperative morbidity and mortality. However, the effects of subtle deviations in serum sodium concentration within the normal range are not well-characterized., Objective: The purpose of this analysis is to determine the association between borderline hyponatremia (135-137 mEq/L) and hypernatremia (143-145 mEq/L) on perioperative morbidity and mortality., Methods: A retrospective cohort study was performed using data from the American College of Surgeons National Surgical Quality Improvement Program database. This database is a repository of surgical outcome data collected from over 600 hospitals across the United States. The National Surgical Quality Improvement Program database was queried to extract all patients undergoing elective, noncardiac surgery from 2015 to 2019. The primary predictor variable was preoperative serum sodium concentration, measured less than 5 days before the index surgery. The 2 primary outcomes were the odds of morbidity and mortality occurring within 30 days of surgery. The risk of both outcomes in relation to preoperative serum sodium concentration was modeled using weighted generalized additive models to minimize the effect of selection bias while controlling for covariates., Results: In the overall cohort, 1,003,956 of 4,551,726 available patients had a serum sodium concentration drawn within 5 days of their index surgery. The odds of morbidity and mortality across sodium levels of 130-150 mEq/L relative to a sodium level of 140 mEq/L followed a nonnormally distributed U-shaped curve. The mean serum sodium concentration in the study population was 139 mEq/L. All continuous covariates were significantly associated with both morbidity and mortality (P<.001). Preoperative serum sodium concentrations of less than 139 mEq/L and those greater than 144 mEq/L were independently associated with increased morbidity probabilities. Serum sodium concentrations of less than 138 mEq/L and those greater than 142 mEq/L were associated with increased mortality probabilities. Hypernatremia was associated with higher odds of both morbidity and mortality than corresponding degrees of hyponatremia., Conclusions: Among patients undergoing elective, noncardiac surgery, this retrospective analysis found that preoperative serum sodium levels less than 138 mEq/L and those greater than 142 mEq/L are associated with increased morbidity and mortality, even within currently accepted "normal" ranges. The retrospective nature of this investigation limits the ability to make causal determinations for these findings. Given the U-shaped distribution of risk, past investigations that assume a linear relationship between serum sodium concentration and surgical outcomes may need to be revisited. Likewise, these results question the current definition of perioperative eunatremia, which may require future prospective investigations., (©Jacob H Cole, Krista B Highland, Scott B Hughey, Brendan J O'Shea, Thomas Hauert, Ashton H Goldman, George C Balazs, Gregory J Booth.

Background: The acute impacts of COVID-19-related mental health concerns on cognitive function among middle-aged and older adults are unknown. We investigated whether between-person (BP) differences and within-person (WP) changes in loneliness, anxiety, and worry about COVID-19 were related to cognitive function and abilities in a longitudinal cohort of middle-aged and older United States (US) adults over a nine-month period during the COVID-19 pandemic., Methods: Data were from bimonthly questionnaires in the nationwide COVID-19 Coping Study from August/September 2020 through April/May 2021 (N = 2262 adults aged ≥55). Loneliness was assessed with the 3-item UCLA Loneliness Scale, anxiety with the 5-item Beck Anxiety Inventory, and COVID-19 worry on a 5-point Likert-type scale. Cognitive outcomes were assessed with the 6-item Patient Reported Outcomes Measurement Information System (PROMIS®) Cognitive Function and Abilities scales. Marginal structural models incorporating inverse probability of treatment and attrition weights as well as sampling weights estimated the BP and WP relationships between the mental health predictors and PROMIS® cognitive scores over time., Results: In any given month, experiencing a loneliness or anxiety symptom score higher than the sample mean (BP difference) or higher than one's personal mean across the nine-month period (WP change) was negatively associated with cognitive function and abilities in that month. The observed magnitudes of associations were stronger for BP differences than for WP changes and were the strongest for anxiety symptom scale scores., Conclusions: Elevated loneliness and anxiety symptoms, both relative to other adults and to one's usual levels, were acutely associated with worse perceived cognitive function and abilities over a nine-month period during the COVID-19 pandemic in the United States. The long-term impacts of mental health symptoms experienced during the pandemic for population cognitive health should be explored., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Lindsay C.

Background and Objectives: This study aimed to examine the associations between multimorbidity at the COVID-19 pandemic onset and subsequent longitudinal trajectories of depressive symptoms, anxiety symptoms, and loneliness in middle-aged and older adults over a 12-month follow-up., Research Design and Methods: Data were from monthly online questionnaires in the COVID-19 Coping Study of U.S. adults aged ≥55 from April/May 2020 through April/May 2021 ( N  = 4,024). Multimorbidity was defined as having ≥2 versus <2 chronic conditions at baseline. Mental health outcomes were assessed monthly as depressive symptoms (8-item Center for Epidemiologic Studies Depression scale), anxiety symptoms (5-item Beck Anxiety Inventory), and loneliness (3-item UCLA Loneliness Scale). We used multivariable-adjusted population- and attrition-weighted mixed-effects linear models to examine the longitudinal associations between multimorbidity and mental health symptoms., Results: Multimorbidity at the pandemic onset was associated with elevated depressive ( b  = 0.37; 95% CI: 0.16-0.59) and anxiety ( b  = 0.39; 95% CI: 0.15-0.62) symptoms at baseline. Changes in symptoms for all three mental health outcomes were nonlinear over time, with worsening symptoms over the first 6 months of the pandemic (April/May to September/October 2020), followed by improvement in symptoms over the subsequent 6 months (September/October 2020 to April/May 2021). Middle-aged and older adults with multimorbidity experienced faster rates of change in anxiety symptoms and loneliness than those without multimorbidity, with persistently elevated mental health symptomatology throughout the follow-up., Discussion and Implications: Results highlight the unique and persistent mental health risks experienced by middle-aged and older adults with multimorbidity during the COVID-19 pandemic. The observed improvements in symptoms underscore the mental resilience of these individuals, indicating their adaptation to the ongoing pandemic., (© The Author(s) 2022.

Purpose: We investigated the relationships between physical isolation at home during the period when many US states had shelter-in-place orders and subsequent longitudinal trajectories of depression, anxiety, and loneliness in older adults over a 6 month follow-up., Methods: Data were from monthly online questionnaires with US adults aged ≥ 55 in the nation-wide COVID-19 Coping Study (April through October 2020, N = 3978). Physical isolation was defined as not leaving home except for essential purposes (0, 1-3, 4-6, and 7 days in the past week), measured at baseline (April-May). Outcomes were depressive symptoms (8-item Center for Epidemiological Studies Depression Scale), anxiety symptoms (5-item Beck Anxiety Inventory), and loneliness (3-item UCLA loneliness scale), measured monthly (April-October). Multivariable, population- and attrition-weighted linear mixed-effects models assessed the relationships between baseline physical isolation with mental health symptoms at baseline and over time., Results: Physical isolation (7 days versus 0 days in the past week) was associated with elevated depressive symptoms (adjusted β = 0.85; 95% CI 0.10-1.60), anxiety symptoms (adjusted β = 1.22; 95% CI 0.45-1.98), and loneliness (adjusted β = 1.06; 95% CI 0.51-1.61) at baseline, but not with meaningful rate of change in these mental health outcomes over time. The symptom burden of each mental health outcome increased with increasing past-week frequency of physical isolation., Conclusion: During the early COVID-19 pandemic, physical isolation was associated with elevated depressive symptoms, anxiety symptoms, and loneliness, which persisted over time. These findings highlight the unique and persistent mental health risks of physical isolation at home under pandemic control measures., (© 2022.

Objectives: Loneliness is associated with increased risks of adverse health outcomes among middle-aged and older adults. We estimated the prevalence of loneliness and identified key sociodemographic, employment, living, and health-related risk factors for loneliness among adults aged ≥55 during the early phase of the COVID-19 pandemic in the United States, when much of the country was under shelter-in-place orders., Methods: We collected data from online questionnaires in the COVID-19 Coping Study, a national study of 6938 US adults aged ≥55 from April 2 through May 31, 2020. We estimated the population-weighted prevalence of loneliness (scores ≥6 of 9 on the 3-item UCLA Loneliness Scale), overall and by sociodemographic, employment, living, and health-related factors. We used population-weighted modified Poisson regression models to estimate prevalence ratios (PRs) and 95% CIs for the associations between these factors and loneliness, adjusting for age, sex, race, ethnicity, and education level., Results: Overall, we estimated that 29.5% (95% CI, 27.9%31.3%) of US adults aged ≥55 were considered high in loneliness in April and May 2020. In population-weighted adjusted models, loneliness was the most prevalent among those who reported depression, who were not married or in a relationship, who lived alone, and who were unemployed at the onset of the pandemic., Conclusions: We identified subpopulations of middle-aged and older adults who were vulnerable to loneliness during a period when COVID-19 shelter-in-place orders were in place across most of the country. These insights may inform the allocation of resources to mitigate an unintended health consequence during times of restricted activity.

Evidence on the role of early-life adversity in later-life memory decline is conflicting. We investigated the relationships between adverse childhood experiences (ACEs) and memory performance and rate of decline over a 10-year follow-up among middle-aged and older adults in England. Data were from biennial interviews with 5,223 participants aged 54 years or older in the population-representative English Longitudinal Study of Ageing from 2006/2007 to 2016/2017. We examined self-reports of 9 ACEs prior to age 16 years that related to abuse, household dysfunction, and separation from family. Memory was assessed at each time point as immediate and delayed recall of 10 words. Using linear mixed-effects models with person-specific random intercepts and slopes and adjusted for baseline age, participants' baseline age squared, sex, ethnicity, and childhood socioeconomic factors, we observed that most individual and cumulative ACE exposures had null to weakly negative associations with memory function and rate of decline over the 10-year follow-up. Having lived in residential or foster care was associated with lower baseline memory (adjusted β = -0.124 standard deviation units; 95% confidence interval: -0.273, -0.025) but not memory decline. Our findings suggest potential long-term impacts of residential or foster care on memory and highlight the need for accurate and detailed exposure measures when studying ACEs in relation to later-life cognitive outcomes., (© The Author(s) 2021.

Objective: Older adults may struggle with stresses and daily life challenges associated with the Coronavirus Disease 2019 (COVID-19) pandemic. Yet they may also utilize emotional and behavioral coping strategies. This qualitative paper aims to identify ways of coping with worries and stress during the pandemic from the perspectives of older adults in the United States. Methods: The COVID-19 Coping Study recruited 6,938 adults aged ≥55 through online multi-frame sampling from April 2-May 31, 2020 across all 50 US states, the District of Columbia, and Puerto Rico. The online questionnaire focused on the effects of COVID-19 on daily life, mental health, and well-being. This included an open-ended question regarding participants' coping strategies. We used qualitative content analysis to identify and code diverse coping strategies. Our general inductive approach enabled findings to emerge from the most frequent and dominant themes in the raw data. Results: A total of 5,180 adults [74% of the total sample; mean age 67.3 (SD 7.9); 63.8% female] responded to the question about using strategies to cope with living through the COVID-19 pandemic. Frequently-reported strategies included exercising and going outdoors, modifying routines, following public health guidelines, adjusting attitudes, and staying socially connected. Some coping strategies were health-limiting (e.g., overeating), while most strategies encouraged self-improvement, positive adjustment, and wellness. Conclusions: This study provides novel qualitative evidence on coping strategies of older adults early in the COVID-19 pandemic. Findings can inform community and clinical interventions to support older adults that harness positive coping strategies such as exercise, modified routines, and social strategies to improve physical and mental health, foster social support, and encourage meaningful daily activities during times of stress and trauma., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Finlay, Kler, O'Shea, Eastman, Vinson and Kobayashi.)

Sources of high-energy photons have important applications in almost all areas of research. However, the photon flux and intensity of existing sources is strongly limited for photon energies above a few hundred keV. Here we show that a high-current ultrarelativistic electron beam interacting with multiple submicrometer-thick conducting foils can undergo strong self-focusing accompanied by efficient emission of gamma-ray synchrotron photons. Physically, self-focusing and high-energy photon emission originate from the beam interaction with the near-field transition radiation accompanying the beam-foil collision. This near field radiation is of amplitude comparable with the beam self-field, and can be strong enough that a single emitted photon can carry away a significant fraction of the emitting electron energy. After beam collision with multiple foils, femtosecond collimated electron and photon beams with number density exceeding that of a solid are obtained. The relative simplicity, unique properties, and high efficiency of this gamma-ray source open up new opportunities for both applied and fundamental research including laserless investigations of strong-field QED processes with a single electron beam.

Purpose: The COVID-19 pandemic, beginning in early 2020, has resulted in massive social, economic, political and public health upheaval around the world. We established a national longitudinal cohort study, the COVID-19 Coping Study, to investigate the effects of pandemic-related stressors and changes in life circumstances on mental health and well-being among middle-aged and older adults in the USA., Participants: From 2 April to 31 May 2020, 6938 adults aged ≥55 years were recruited from all 50 US states, the District of Columbia and Puerto Rico using online, multi-frame non-probability-based sampling., Findings to Date: Mean age of the baseline sample was 67.3 years (SD: 7.9 years) and 64% were women. Two in three adults reported leaving home only for essential purposes in the past week (population-weighted proportion: 69%; 95% CI: 68% to 71%). Nearly one in five workers aged 55-64 years was placed on a leave of absence or furloughed since the start of the pandemic (17%; 95% CI: 14% to 20%), compared with one in three workers aged ≥75 years (31%; 95% CI: 21% to 44%). Nearly one-third of adults screened positive for each of depression (32%; 95% CI: 30% to 34%), anxiety (29%; 28% to 31%) and loneliness (29%; 95% CI: 27% to 31%), with decreasing prevalence of each with increasing age., Future Plans: Monthly and annual follow-ups of the COVID-19 Coping Study cohort will assess longitudinal changes to mental health, cognitive health and well-being in relation to social, behavioural, economic and other COVID-19-related changes to life circumstances. Quantitative and in-depth qualitative interview data will be collected through online questionnaires and telephone interviews. Cohort data will be archived for public use., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021. Re-use permitted under CC BY-NC.

Wakefield based accelerators capable of accelerating gradients 2 orders of magnitude higher than present accelerators offer a path to compact high energy physics instruments and light sources. However, for high gradient accelerators, beam instabilities driven by commensurately high transverse wakefields limit beam quality. Previously, it has been theoretically shown that transverse wakefields can be reduced by elliptically shaping the transverse sizes of beams in dielectric structures with planar symmetry. Here, we report experimental measurements that demonstrate reduced transverse wakefields for elliptical beams in planar symmetric structures which are consistent with theoretical models. These results may enable the design of gigavolt-per-meter gradient wakefield based accelerators that produce and stably accelerate high quality beams.

Background: The collateral (or informant) history is a key component in the assessment of older adults presenting with a memory problem or concern over cognition. Despite this, it rarely features in medical literature and academic curricula. Its role in general practice has never been assessed., Aims: The aim of this study is to assess the role of the collateral history in the investigation of cognitive impairment in general practice., Methods: An online survey distributed to three nationally representative cohorts of GPs in Ireland (n = 692)., Results: Ninety-five (14%; 52.2% male) responded. Nearly all (87%; 83/95) indicate that it is most often a family member who brings possible cognitive impairment to the attention of their GP. The vast majority obtain a collateral history in > 90% of cases (72.6%; 69/95) and rate it very useful in their clinical assessment of cognition. GPs report the collateral history as readily available and rarely refused, with the general practice environment well-suited to obtaining collateral histories. A small minority routinely use the GPCOG informant section (3.2%; 3/95). Nearly all (92.6%; 88/95) report having received no training in obtaining collateral histories with most (79%; 75/95) welcoming of further training in this area., Conclusions: Despite recognition of the utility and importance of the collateral history, the vast majority of GPs report having never received training in obtaining one and do not use structured tools to guide their interview. Further emphasis on the informant history as a distinct clinical entity on medical curricula and increasing emphasis on the availability of structured informant tools are warranted.

Background: End-of-life planning means decision making with patients, formulating and recording decisions regarding their end-of-life care. Although clearly linked with benefits including improved quality of life, reduced hospital admissions, and less aggressive medical care, it is still infrequently undertaken and is regarded as challenging by healthcare professionals., Aim: To ascertain the feasibility of improving the identification of patients at high risk of dying in general practice and the acceptability of providing patients identified with an end-of-life planning tool., Design and Setting: Exploratory prospective cross-sectional study in four general practices., Method: Patients at high risk of dying were identified during routine consulting by their GP, using the Supportive and Palliative Care Indicators Tool (SPICT). Patients identified were invited to participate, and provided with Think Ahead - an end-of-life planning tool, which has been used previously in general practice. Participants completed telephone surveys, assessing their response to Think Ahead, and the acceptability of the GP raising end-of-life issues during routine consulting., Results: Provision of Think Ahead to a purposive sample of preterminal patients identified by GPs was feasible, acceptable to most patients, and somewhat effective in increasing discussion among families and in practice on end-of-life planning., Conclusion: The SPICT and Think Ahead tools were mostly acceptable, effective, and enabling of discussions on end-of-life care in general practice., (© British Journal of General Practice 2016.)

Background: General Practice Co-Operatives provide most out of hours care in communities in Ireland. Limited data exists on patient complaints. This study reports on complaints at Kildare and West Wicklow Doctors on Call ('K Doc'), a GP Co-Operative in Ireland, examining the impact of a formal risk reduction strategy implemented (2010-2013). The aim of the study was to determine if it was possible to reduce the rate of written complaints per 1000 consultations through a formal approach encompassing evaluation of complaints, improved communication in relation to complaints, and more direct use of insights gained from complaints analysis in continuing professional development at the Co-Operative., Methods: Initially, complaints submitted over an 18 month period (01.06.08 to 31.12.09) were analysed. Complaint rate (number of complaints per 1000 consultations), complainant demographics, aspects of complaint response at the Co-Operative, and nature of complaint were recorded. Based on analysis, a risk reduction strategy was undertaken, including procedural change, focused training and education. Areas selected for improvement during a second phase of data collection included complaints rate, timeliness of Co-Operative response to complaint, and rate of complaint notification to patient's GP. Further analysis was then carried out over a 45 month period (01.01.10 to 30.09.13)., Results: From 2008-2013, 216,716 patient consultations occurred. Complaints were received from 131 individuals, regarding 125 patients. Following introduction of risk reduction strategy, complaints rate reduced by 36 %, from 0.77 to 0.49 per 1000 consultations (p = 0.02) between the two periods of data collection. Timeliness of response from Co-Operative to the complainant improved from 63 % to 75 %. Notification of complaint to the patient's GP improved from 48 % to 96 %. Most complaints were not associated with medically significant events. The largest categories of complaint related to clinical care (55 % n = 69), cost (46 %, n = 58), communication (42 %, n = 53), and process of care (15 %, n = 19). Mothers of affluent paediatric patients were most likely to make formal complaints., Conclusions: This study reports a statistically significant reduction in complaints rate of 36 % following introduction of risk reduction strategies at a GP Co -Operative. Out of hours consulting is known to be an area of high medical risk. Findings are of interest where number and costs of complaints against GPs are elsewhere reported to be rising, contributing to medical inflation, and to public concern.

Plasma wakefield accelerators have been used to accelerate electron and positron particle beams with gradients that are orders of magnitude larger than those achieved in conventional accelerators. In addition to being accelerated by the plasma wakefield, the beam particles also experience strong transverse forces that may disrupt the beam quality. Hollow plasma channels have been proposed as a technique for generating accelerating fields without transverse forces. Here we demonstrate a method for creating an extended hollow plasma channel and measure the wakefields created by an ultrarelativistic positron beam as it propagates through the channel. The plasma channel is created by directing a high-intensity laser pulse with a spatially modulated profile into lithium vapour, which results in an annular region of ionization. A peak decelerating field of 230 MeV m(-1) is inferred from changes in the beam energy spectrum, in good agreement with theory and particle-in-cell simulations.

Background: Think Ahead is a public awareness initiative of the Forum on End of Life in Ireland. The Think Ahead Form (www.thinkahead.ie) guides people in recording important information in the event that they are unable to speak for themselves, due to serious illness, emergency or death., Aim: To engage the public to use Think Ahead and to build capacity of community organisations and health care professionals to empower people to use the tool if they wish., Method: A 'Think Ahead' form and website were designed and launched as guidance tools for the public. A range of processes were also engaged in, including: Public consultation Consultation with key stakeholders GP research: involving 120 people up to 70 years of age, examined people's experiences of filling in the Think Ahead form Nursing home research: involving staff and residents in nursing homes in Kildare in 2014 Regional community- based pilots: Regional pilots took place in Limerick and Louth, late 2012 Train the trainer programmes with community organisations, Results: Very positive outcomes for patients and GPs Nursing home staff empowered to enable residents to express their preferences 80% of public believed that Think Ahead would be of interest to the general public 30,000 forms distributed since 2011 Active Retirement Ireland rolling out Think Ahead, Conclusion: The research and public engagement activities have shown that Think Ahead is a citizen-led practical tool which people can use as part of their planning for end of life., (© 2015, Published by the BMJ Publishing Group Limited.

Background: Methadone maintenance treatment in primary care is cost-effective and improves outcomes for opiate-dependent patients. A more developed understanding of the evolving needs of this important cohort will facilitate further improvements in their integrated care within the community., Objectives: The aim of this study was to compare the burden of chronic disease, multi-morbidity and intensity of health-service use between methadone-maintained patients (MMPs) and matched controls in primary care., Methods: This is a retrospective matched case-control design. Data on chronic disease and health service use was collected in 13 computerized GP surgeries on 414 patients (207 MMPs and 207 controls). Twelve months of records were examined. MMPs were compared with controls matched by gender, age, socio-economic status (SES) and GP surgery., Results: MMPs suffered more chronic disease (OR = 9.1, 95% CI: 5.4-15.1, P < 0.001) and multi-morbidity (OR = 6.6, 95% CI: 4.3-10.2, P < 0.001). They had higher rates of respiratory, psychiatric and infectious disease. MMPs of lower SES had more chronic disease than their peers (OR = 7.2, 95% CI: 2.4-22.0, P < 0.001). MMPs attended the doctor more often with medical problems (OR = 15.4, 95% CI: 8.2-28.7, P < 0.001), with a frequent requirement to have medical issues addressed during methadone-management visits. Their care generated more telephone calls (OR = 4.4, 95% CI: 2.8-6.8, P < 0.001), investigations (OR = 1.8, 95% CI: 1.2-2.7, P = 0.003), referrals (2.6, 95% CI: 1.7-4.0, P < 0.001), emergency department visits (2.1, 95% CI: 1.3-3.6, P = 0.004), outpatient attendances (2.3, 95% CI: 1.51-1.43, P < 0.001) and hospital admissions (3.6, 95% CI: 1.6-8.1, P = 0.001)., Conclusion: Correcting for routine methadone care and drug-related illnesses, MMPs had a higher burden of chronic disease and used both primary and secondary health services more intensively than matched controls.

Background: General practitioners (GPs) do not routinely check children's weight, partly due to concern regarding parental/child response. The aim of this study is to compare GP concerns regarding weighing with parental/child responses., Objective: Compare GP insights on weighing children with the experience of parents whose children had been weighed., Methods: Part 1: postal survey of 20% sample of Irish GPs. Part 2: general practice-based study checking weight of 5-12 year olds attending 10 practices, with postconsultation parental survey., Setting: Irish General Practice., Participants: 393 GPs and 457 parents., Outcome Measures: GP (n=393) and parental (n=434) responses., Results: Of 490 GPs surveyed, 393 responded (response rate 80.2%). Few GPs (3.56%) always checked children's weight. Concern regarding parental response was often (52.2%) or always (19.0%) a concern that affected the likelihood of discussing a child's weight. Among children (n=457), 14.9% were overweight and 10.9% obese. Almost all (98.6%) parents indicated checking weight was helpful. 4.4% of parents and just over 1 in 4 obese children responded negatively to weighing. Overweight children were more likely to respond negatively (χ(2)=62.6, df=4, p<0.001). Children 5-6 years were most likely to respond positively., Conclusions: GPs are conflicted regarding the acceptability of weighing the child but almost all parents believed it helpful. A minority of obese children responded negatively., (Published by the BMJ Publishing Group Limited.

Malaria includes a global disease burden with approximately 300-500 million cases worldwide annually. Varied symptomatology creates a diagnostic challenge. This is a case report of a stroke rehabilitation facility resident who developed Plasmodium ovale infection, several months post-exposure. Physicians should maintain a broad list of differential diagnoses, thinking beyond the range of common diagnoses.

Rationale: Complex adaptive chronic care (CACC) is a framework based upon complex adaptive systems' theory developed to address different stages in the patient journey in chronic illness. Simple, complicated, complex and chaotic phases are proposed as diagnostic types., Aims: To categorize phases of the patient journey and evaluate their utility as diagnostic typologies., Methods: A qualitative case study of two cohorts, identified as being at risk of avoidable hospitalization: 12 patients monitored to establish typologies, followed by 46 patients to validate the typologies. Patients were recruited from a general practitioner out-of-hours service. Self-rated health, medical and psychological health, social support, environmental concerns, medication adherence and health service use were monitored with phone calls made 3-5 times per week for an average of 4 weeks. Analysis techniques included frequency distributions, coding and categorization of patients' longitudinal data using a CACC framework., Findings: Twelve and 46 patients, mean age 69 years, were monitored for average of 28 days in cohorts 1 and 2 respectively. Cohorts 1 and 2 patient journeys were categorized as being: stable complex 66.66% vs. 67.4%, unstable complex 25% vs. 26.08% and unstable complex chaotic 8.3% vs. 6.52% respectively. An average of 0.48, 0.75 and 2 interventions per person were provided in the stable, unstable and chaotic journeys. Instability was related to complex interactions between illness, social support, environment, as well as medication and medical care issues., Conclusion: Longitudinal patient journeys encompass different phases with characteristic dynamics and are likely to require different interventions and strategies - thus being 'adaptive' to the changing complex dynamics of the patient's illness and care needs. CACC journey types provide a clinical tool for health professionals to focus time and care interventions in response to patterns of instability in multiple domains in chronic illness care., (© 2011 Blackwell Publishing Ltd.)
