Proton pump inhibitors and dementia risk: Evidence from a cohort study using linked routinely collected national health data in Wales, UK.

OBJECTIVES: Proton pump inhibitors (PPIs) are commonly prescribed for prevention and treatment of gastrointestinal conditions or for gastroprotection from other drugs. Research suggests they are linked to increased dementia risk. We use linked national health data to examine the association between PPI use and the development of incident dementia. METHODS AND FINDINGS: A population-based study using electronic health-data from the Secure Anonymised Information Linkage (SAIL) Databank, Wales (UK) from 1999 to 2015. Of data available on 3,765,744 individuals, a cohort who had ever been prescribed a PPI was developed (n = 183,968) for people aged 55 years and over and compared to non-PPI exposed individuals (131,110). Those with prior dementia, mild-cognitive-impairment or delirium codes were excluded. Confounding factors included comorbidities and/or drugs associated with them. Comorbidities might include head injury and some examples of medications include antidepressants, antiplatelets and anticoagulants. These commonly prescribed drugs were investigated as it was not feasible to explore all drugs in this study. The main outcome was a diagnosis of incident dementia. Cox proportional hazard regression modelling was used to calculate the Hazard ratio (HR) of developing dementia in PPI-exposed compared to unexposed individuals while controlling for potential confounders. The mean age of the PPI exposed individuals was 69.9 years and 39.8% male while the mean age of the unexposed individuals was 72.1 years and 41.1% male. The rate of PPI usage was 58.4% (183,968) and incident dementia rate was 11.8% (37,148/315,078). PPI use was associated with decreased dementia risk (HR: 0.67, 95% CI: 0.65 to 0.67, p<0.01). CONCLUSIONS: This study, using large-scale, multi-centre health-data was unable to confirm an association between PPI use and increased dementia risk. Previously reported links may be associated with confounders of people using PPI's, such as increased risk of cardiovascular disease and/or depression and their associated medications which may be responsible for any increased risk of developing dementia.

The nature, characteristics and associations of care home staff stress and wellbeing: a national survey.

BACKGROUND: The majority of residents in care homes in the United Kingdom are living with dementia or significant memory problems. Caring in this setting can be difficult and stressful for care staff who work long hours, have little opportunity for training, are poorly paid and yet subject to high expectation. This may affect their mental and physical wellbeing, cause high rates of staff turnover and absenteeism, and affect the quality of care they provide. The main objective of this survey was to explore the nature, characteristics and associations of stress in care home staff. METHODS: Staff working in a stratified random sample of care homes within Wales completed measures covering: general health and wellbeing (SF-12); stress (Work Stress Inventory); job content (Karasek Job Content); approach to, and experience of, working with people living with dementia (Approaches to Dementia Questionnaire; and Experience of Working with Dementia Patients); and Productivity and Health Status (SPS-6). Multiple linear regressions explored the effects of home and staff characteristics on carers. RESULTS: 212 staff from 72 care homes completed questionnaires. Staff from nursing homes experienced more work stress than those from residential homes (difference 0.30; 95% confidence interval (CI) from 0.10 to 0.51; P < 0.01), and were more likely to report that their health reduced their ability to work (difference -4.77; CI -7.80 to -1.73; P < 0.01). Psychological demands on nurses were higher than on other staff (difference = 1.57; CI 0.03 to 3.10; P < 0.05). A positive approach to dementia was more evident in those trained in dementia care (difference 8.54; CI 2.31 to 14.76; P < 0.01), and in staff working in local authority homes than in the private sector (difference 7.75; CI 2.56 to 12.94; P < 0.01). CONCLUSIONS: Our study highlights the importance of dementia training in care homes, with a particular need in the private sector. An effective intervention to reduce stress in health and social care staff is required, especially in nursing and larger care homes, and for nursing staff.

Newspaper Reporting on a Cluster of Suicides in the UK.

BACKGROUND: Media reporting may influence suicide clusters through imitation or contagion. In 2008 there was extensive national and international newspaper coverage of a cluster of suicides in young people in the Bridgend area of South Wales, UK. AIMS: To explore the quantity and quality of newspaper reporting during the identified cluster. METHOD: Searches were conducted for articles on suicide in Bridgend for 6 months before and after the defined cluster (June 26, 2007, to September 16, 2008). Frequency, quality (using the PRINTQUAL instrument), and sensationalism were examined. RESULTS: In all, 577 newspaper articles were identified. One in seven articles included the suicide method in the headline, 47.3% referred to earlier suicides, and 44% used phrases that guidelines suggest should be avoided. Only 13% included sources of information or advice. CONCLUSION: A high level of poor-quality and sensationalist reporting was found during an ongoing suicide cluster at the very time when good-quality reporting could be considered important. A broad awareness of media guidelines and expansion and adherence to press codes of practice are required by journalists to ensure ethical reporting.

Nurse-Led Medicines' Monitoring for Patients with Dementia in Care Homes: A Pragmatic Cohort Stepped Wedge Cluster Randomised Trial.

BACKGROUND: People with dementia are susceptible to adverse drug reactions (ADRs). However, they are not always closely monitored for potential problems relating to their medicines: structured nurse-led ADR Profiles have the potential to address this care gap. We aimed to assess the number and nature of clinical problems identified and addressed and changes in prescribing following introduction of nurse-led medicines' monitoring. DESIGN: Pragmatic cohort stepped-wedge cluster Randomised Controlled Trial (RCT) of structured nurse-led medicines' monitoring versus usual care. SETTING: Five UK private sector care homes. PARTICIPANTS: 41 service users, taking at least one antipsychotic, antidepressant or anti-epileptic medicine. INTERVENTION: Nurses completed the West Wales ADR (WWADR) Profile for Mental Health Medicines with each participant according to trial step. OUTCOMES: Problems addressed and changes in medicines prescribed. DATA COLLECTION AND ANALYSIS: Information was collected from participants' notes before randomisation and after each of five monthly trial steps. The impact of the Profile on problems found, actions taken and reduction in mental health medicines was explored in multivariate analyses, accounting for data collection step and site. RESULTS: Five of 10 sites and 43 of 49 service users approached participated. Profile administration increased the number of problems addressed from a mean of 6.02 [SD 2.92] to 9.86 [4.48], effect size 3.84, 95% CI 2.57-4.11, P <0.001. For example, pain was more likely to be treated (adjusted Odds Ratio [aOR] 3.84, 1.78-8.30), and more patients attended dentists and opticians (aOR 52.76 [11.80-235.90] and 5.12 [1.45-18.03] respectively). Profile use was associated with reduction in mental health medicines (aOR 4.45, 1.15-17.22). CONCLUSION: The WWADR Profile for Mental Health Medicines can improve the quality and safety of care, and warrants further investigation as a strategy to mitigate the known adverse effects of prescribed medicines. TRIAL REGISTRATION: ISRCTN 48133332.

The effect of physical activity and motivation on function in ankylosing spondylitis: a cohort study.

OBJECTIVES: Exercise is reported to improve function for people with ankylosing spondylitis (AS) but it is not clear if this effect is causal or if patients with milder disease find it easier to exercise. This study examines the effect of exercise and motivation to exercise on function, while controlling for disease severity. METHODS: Participants who were members of an existing AS cohort were asked about physical activity, motivation to exercise, function, and disease severity. Path analysis on STATA was used to examine the correlation between factors associated with function at time of exercise and with function after 3 months of follow-up. RESULTS: The response rate to the questionnaire was 88% (326/371). Improvement in function was greatest for people with higher physical activity levels and those who were more motivated to exercise-this was especially the case for patients with the most severe disease activity. The effect of motivation to exercise not only had a direct effect on function, but also an indirect effect of improving activity levels thereby improving both current and future function. People with high intrinsic motivation (driven by pleasure) had the greatest benefit to activity and function. CONCLUSIONS: Exercise does improve function, especially for those with severe disease. In addition, motivation alone improves function as much as exercising itself. Therefore, interventions targeting motivation to exercise would have as much effect on improving function as interventions offering exercise opportunities. In addition, any intervention that both improves motivation and increases opportunities to exercise would have a 2-fold influence on function.

Fatigue in ankylosing spondylitis: treatment should focus on pain management.

OBJECTIVES: Fatigue is an important symptom associated with ankylosing spondylitis (AS). This study examines patients' perspectives and clinical associations of fatigue to help inform potential strategies to alleviate fatigue in AS. METHODS: A mixed methods approach was taken to examine fatigue in a cohort of people with AS. Fatigue levels were evaluated from 3 consecutive monthly questionnaires. Open-ended questions on fatigue were analyzed using thematic analysis and logistic regression was used to examine quantitative data. In addition, fatigue levels were examined before and after treatment with anti-tumor necrosis factor (TNF) compared to nontreated controls. RESULTS: Three hundred forty-eight of 385 participants completed a fatigue questionnaire. Fatigue was reported to have significant physical, social, and psychological effects. A third of the participants reported that there was nothing they could do to reduce their fatigue, whereas other participants reported that medication, exercise, and resting helped. The main factor associated with fatigue was pain [ß-coefficient: 0.74 (95% CI: 0.66 to 0.81)], whereas depression was much less strongly associated. However, these factors only explained 40% of the variation in fatigue levels. Starting anti-TNF therapy reduced fatigue and pain levels compared to the period of time before taking anti-TNF [difference: 14.4 (95% CI: 5.3 to 23.5) on a scale of 0-100] and this reduction was not seen in controls over the same period. CONCLUSIONS: Fatigue is not strongly associated with anxiety, motivation, and depression; instead the factor most associated with fatigue is pain. This suggests that in addition to treatments to reduce disease activity, strategies for alleviating fatigue in AS should focus on pain management techniques and actively treating inflammation.

Feelings of loneliness among adults with mental disorder.

PURPOSE: Loneliness can affect people at any time and for some it can be an overwhelming feeling leading to negative thoughts and feelings. The current study, based on the Adult Psychiatric Morbidity Survey in England, 2007, quantified the association of loneliness with a range of specific mental disorders and tested whether the relationship was influenced by formal and informal social participation and perceived social support.Methods Using a random probability sample design,7,461 adults were interviewed in a cross-sectional national survey in England in 2007. Common Mental Disorders were assessed using the revised Clinical Interview Schedule;the diagnosis of psychosis was based on the administration of the Schedules of the Clinical Assessment of Neuropsychiatry, while loneliness was derived from an item in the Social Functioning Questionnaire.Results Feelings of loneliness were more prevalent in women (OR = 1.34, 95 % CI 1.20­1.50, P\0.001) as well as in those who were single (OR = 2.24, 95 % C I1.96­2.55, P<0.001), widowed, divorced or separated(OR = 2.78, 95 % CI 2.38­3.23, P<0.001), economically inactive (OR = 1.24, 95 % CI 1.11­1.44,P = 0.007), living in rented accommodation (OR = 1.73,95 % CI 1.53­1.95, P<0.001) or in debt (OR = 2.47,95 % CI 2.07­1.50, P<0.001). Loneliness was associated with all mental disorders, especially depression [corrected].

Self-harm in older people: a clear need for specialist assessment and care.

Suicide rates are generally elevated after episodes of non-fatal self-harm, especially among older adults. Evidence suggests that non-fatal and fatal self-harm are more closely related in older than in younger adults. Older people who have self-harmed need specialist assessment followed by good short-term and long-term evidence-based care.

Physical ill health, disability, dependence and depression: results from the 2007 national survey of psychiatric morbidity among adults in England.

BACKGROUND: The relationship between physical ill health, disability, and depression is not straightforward. Both cross-sectional and longitudinal studies have clearly shown that medical illness and physical disability are strongly associated with depression. OBJECTIVE: To test the hypothesis that disability is associated with an increased prevalence of depression irrespective of physical health problems and that this is proportionate to the severity of disability (measured in terms of the number of difficulties in daily activities and the degree of dependence on others). METHODS: Using a random probability sample design, 7460 respondents were interviewed for the third national survey of psychiatric morbidity of adults in the private household population in England. Fieldwork was carried out throughout 2007. The prevalence of depression was established by the administration of the revised Clinical Interview Schedule (CIS-R), while disability was measured by reported difficulties in activities of daily living (ADL) and instrumental activities of daily living (IADL). RESULTS: Disability was associated with depression even after adjustment for physical ill health. The number of ADL/IADL difficulties was directly related to the likelihood of respondents having depression. Dependence on others was not associated with depression once severity of disability had been accounted for. CONCLUSION: All ADL/IADL limitations are significantly associated with depression and there seems to be a cumulative effect irrespective of whether the limitation is in personal care or in instrumental activities such as mobility problems.

The role of vascular risk factors in late onset bipolar disorder.

BACKGROUND: The association between late life depression and cerebro-vascular risk and cerebro-vascular disease is well established. Do similar links exist with late onset bipolar disorder? AIMS AND OBJECTIVES: Patients with early onset (less than 60 years of age) bipolar disorder were compared with those of late onset (aged 60 and above) in relation to cognitive function, physical health and vascular risk factors. METHOD: Cross-sectional survey of elderly bipolar disorder patients (above 65 years) involved with secondary care mental health services. Thirty patients with early onset were compared with 20 patients with a late onset bipolar disorder. Diagnosis of bipolar disorder was according to ICD-10 criteria and without an associated clinical diagnosis of dementia. Assessment of cognition included tests of frontal-executive function, and cerebro-vascular risk was quantified with the Framingham stroke risk score. RESULTS: The late onset group had a higher stroke risk score than the early onset group, this difference persisting despite taking age and gender differences into account. However, late onset patients' cognitive function (including frontal lobe tests) and physical health status was no different to the early onset group. CONCLUSION: There is higher 'cerebrovascular risk' in elderly patients with late onset bipolar disorder, compared to patients with an early onset. This suggests that cerebrovascular risk may be an important factor for the expression of bipolar disorders in later life, and has significant management implications for older bipolar patients.
