Parathyroid hormone, cognitive function and dementia: a systematic review

BACKGROUND: Metabolic factors are increasingly recognized to play an important role in the pathogenesis of Alzheimer's disease and dementia. Abnormal parathyroid hormone (PTH) levels play a role in neuronal calcium dysregulation, hypoperfusion and disrupted neuronal signaling. Some studies support a significant link between PTH levels and dementia whereas others do not. METHODS: We conducted a systematic review through January 2014 to evaluate the association between PTH and parathyroid conditions, cognitive function and dementia. Eleven electronic databases and citation indexes were searched including Medline, Embase and the Cochrane Library. Hand searches of selected journals, reference lists of primary studies and reviews were also conducted along with websites of key organizations. Two reviewers independently screened titles and abstracts of identified studies. Data extraction and study quality were performed by one and checked by a second reviewer using predefined criteria. A narrative synthesis was performed due to the heterogeneity of included studies. RESULTS: The twenty-seven studies identified were of low and moderate quality, and challenging to synthesize due to inadequate reporting. Findings from six observational studies were mixed but suggest a link between higher serum PTH levels and increased odds of poor cognition or dementia. Two case-control studies of hypoparathyroidism provide limited evidence for a link with poorer cognitive function. Thirteen pre-post surgery studies for primary hyperparathyroidism show mixed evidence for improvements in memory though limited agreement in other cognitive domains. There was some degree of cognitive impairment and improvement postoperatively in observational studies of secondary hyperparathyroidism but no evident pattern of associations with specific cognitive domains. CONCLUSIONS: Mixed evidence offers weak support for a link between PTH, cognition and dementia due to the paucity of high quality research in this area.NIHR PenCLAHRCAlzheimer’s AssociationRosetrees TrustMary Kinross Charitable TrustJames Tudor FoundationHalpin TrustNorman Family Charitable Trus

School exclusion in children with psychiatric disorder or impairing psychopathology: a systematic review

This is an Accepted Manuscript of an article published by Taylor & Francis in Emotional and Behavioural Difficulties on 20 August 2014, available online: http://wwww.tandfonline.com/10.1080/13632752.2014.945741Childhood psychiatric disorders are associated with a wide range of adverse outcomes including poor academic attainment. For some children these difficulties are recognised through school Special Educational Need procedures (SEN) but many others may remain unidentified and/or unsupported. In Britain, government data suggests disproportionate representation of children with a SEN among children permanently excluded from school. This review asks whether school-aged children with impairing psychopathology were more likely to be excluded from school than those without. Databases covering education, social sciences, psychology and medicine were searched, experts were contacted and bibliographies of key papers were hand-searched. Studies were included if the population covered school-aged children, and if validated diagnostic measures had been used to assess psychopathology. Children with impairing psychopathology had greater odds of exclusion compared to the rest of the school-age population: odds ratios range from 1.13 (95% CI: 0.55–2.33) to 45.6 (95% CI: 3.8–21.3). These findings however need to be considered in light of the paucity of the literature and methodological weaknesses discussed.National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for the South West Peninsula

Multiple component interventions for preventing falls and fall-related injuries among older people: systematic review and meta-analysis

BACKGROUND: Limited attention has been paid in the literature to multiple component fall prevention interventions that comprise two or more fixed combinations of fall prevention interventions that are not individually tailored following a risk assessment. The study objective was to determine the effect of multiple component interventions on fall rates, number of fallers and fall-related injuries among older people and to establish effect sizes of particular intervention combinations. METHODS: Medline, EMBASE, CINAHL, PsychInfo, Cochrane, AMED, UK Clinical Research Network Study Portfolio, Current Controlled Trials register and Australian and New Zealand Clinical Trials register were systematically searched to August 2013 for randomised controlled trials targeting those aged 60 years and older with any medical condition or in any setting that compared multiple component interventions with no intervention, placebo or usual clinical care on the outcomes reported falls, number that fall or fall-related injuries. Included studies were appraised using the Cochrane risk of bias tool. Estimates of fall rate ratio and risk ratio were pooled across studies using random effects meta-analysis. Data synthesis took place in 2013. RESULTS: Eighteen papers reporting 17 trials were included (5034 participants). There was a reduction in the number of people that fell (pooled risk ratio = 0.85, 95% confidence interval (95% CI) 0.80 to 0.91) and the fall rate (pooled rate ratio = 0.80, 95% CI 0.72 to 0.89) in favour of multiple component interventions when compared with controls. There was a small amount of statistical heterogeneity (I(2) =20%) across studies for fall rate and no heterogeneity across studies examining number of people that fell. CONCLUSIONS: This systematic review and meta-analysis of randomised controlled trials found evidence that multiple component interventions that are not tailored to individually assessed risk factors are effective at reducing both the number of people that fall and the fall rate. This approach should be considered as a service delivery option.National Institute for Health Research (NIHR) Collaboration for Applied Health Research and Care (CLAHRC) for the South West Peninsul

Depression is more common among individuals with chronic physical illness than in the general population. New treatments for severe and chronic inflammatory conditions which inhibit tumour necrosis factor alpha (TNFα), a pro-inflammatory cytokine, may be able to shed some light on the role of inflammatory mediators in depression. This systematic review and meta-analysis of randomised controlled trials determined the effects of TNFα inhibitor therapy on depression and anxiety in people with chronic physical illness.This systematic review was funded by the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care South West Peninsula at the Royal Devon and Exeter NHS Foundation Trust

Non-pharmacological interventions for ADHD in school settings: an overarching synthesis of systematic reviews

OBJECTIVE: This overarching synthesis brings together the findings of four systematic reviews including 138 studies focused on non-pharmacological interventions for ADHD used in school settings. These reviews considered the effectiveness of school-based interventions for ADHD, attitudes toward and experience of school-based interventions for ADHD, and the experience of ADHD in school settings. METHOD: We developed novel methods to compare the findings across these reviews inductively and deductively. RESULTS: Key contextual issues that may influence the effectiveness and implementation of interventions include the relationships that pupils with ADHD have with their teachers and peers, the attributions individuals make about the etiology of ADHD, and stigma related to ADHD or intervention attendance. CONCLUSION: Although we found some positive effects for some outcomes and intervention categories, heterogeneity in effect size estimates and research evidence suggests a range of diverse contextual factors potentially moderate the implementation and effectiveness of school-based interventions for ADHD.National Institute for Health Research Health Technology Assessment (NIHR HTA) programNIHR Collaboration for Leadership in Applied HealthResearch and Care South West Peninsula (PenCLAHRC

Is volunteering a public health intervention? A systematic review and meta-analysis of the health and survival of volunteers

Background Volunteering has been advocated by the United Nations, and American and European governments as a way to engage people in their local communities and improve social capital, with the potential for public health benefits such as improving wellbeing and decreasing health inequalities. Furthermore, the US Corporation for National and Community Service Strategic Plan for 2011–2015 focused on increasing the impact of national service on community needs, supporting volunteers’ wellbeing, and prioritising recruitment and engagement of underrepresented populations. The aims of this review were to examine the effect of formal volunteering on volunteers’ physical and mental health and survival, and to explore the influence of volunteering type and intensity on health outcomes. Methods Experimental and cohort studies comparing the physical and mental health outcomes and mortality of a volunteering group to a non-volunteering group were identified from twelve electronic databases (Cochrane Library, Medline, Embase, PsychINFO, CINAHL, ERIC, HMIC, SSCI, ASSIA, Social Care Online, Social Policy and Practice) and citation tracking in January 2013. No language, country or date restrictions were applied. Data synthesis was based on vote counting and random effects meta-analysis of mortality risk ratios. Results Forty papers were selected: five randomised controlled trials (RCTs, seven papers); four non-RCTs; and 17 cohort studies (29 papers). Cohort studies showed volunteering had favourable effects on depression, life satisfaction, wellbeing but not on physical health. These findings were not confirmed by experimental studies. Meta-analysis of five cohort studies found volunteers to be at lower risk of mortality (risk ratio: 0.78; 95% CI: 0.66, 0.90). There was insufficient evidence to demonstrate a consistent influence of volunteering type or intensity on outcomes. Conclusion Observational evidence suggested that volunteering may benefit mental health and survival although the causal mechanisms remain unclear. Consequently, there was limited robustly designed research to guide the development of volunteering as a public health promotion intervention. Future studies should explicitly map intervention design to clear health outcomes as well as use pragmatic RCT methodology to test effects

The Impact of a Public Health Crisis on the Well-Being of UK Senior Care Home Staff: A Qualitative Interview Study

Context: Care homes in the UK were hit badly by the COVID-19 pandemic, with numerous outbreaks and deaths of residents and staff. Objectives: To capture the impact of the pandemic on care home staff well-being and share insights and learning about how to optimise support for the workforce. Methods: Fifteen senior care staff from care homes looking after older people in England were interviewed between December 2020 and March 2021, when the sector was still under strict restriction measures. The topic guide was developed in consultation with care home staff. Interviews were transcribed and analysed using a reflexive thematic analysis approach to identify themes and sub-themes of the impact on staff well-being. Findings: The impact of the pandemic was overwhelmingly negative, with those interviewed reporting both mental and physical health implications. We identified three themes: emotional exhaustion (upset and trauma, increased responsibility and workload, feelings of guilt); frustration (feeling misunderstood, undervalued, unrecognised, abandoned); and relationships (the importance of supportive working relationships within the care home and with external agencies). Limitations: Staff interviewed were managers or in other senior roles; it would be beneficial to synthesise this research with studies involving other care home staff and residents and their relatives. Given the disparate nature of the care home sector, a larger sample may have identified additional insights. Implications: This study provides insight into the resilience of care home staff during the pandemic and challenges to this; this could help to inform future efforts as to support of the workforce and sector

Interventions to improve continence for children and young people with neurodisability: a national survey of practitioner and family perspectives and experiences.

Objective Describe families’ experiences of interventions to improve continence in children and young people with neurodisability, and health professionals’ and school and social care staff’s perspectives regarding factors affecting intervention use. Design Four online surveys were developed and advertised to parent carers, young people with neurodisability, health professionals and school and social care staff, via societies, charities, professional contacts, schools, local authorities, and national parent carer and family forums, who shared invitations with their networks. Survey questions explored: difficulties helping children and young people use interventions; acceptability of interventions and waiting times; ease of use and availability of interventions, and facilitators and barriers to improving continence. Results 1028 parent carers, 26 young people, 352 health professionals and 202 school and social care staff registered to participate. Completed surveys were received from 579 (56.3%) parent carers, 20 (77%) young people, 193 (54.8%) health professionals, and 119 (58.9%) school and social care staff. Common parent carer-reported difficulties in using interventions to help their children and young people to learn to use the toilet included their child’s lack of understanding about what was required (reported by 337 of 556 (60.6%) parent carers who completed question) and their child’s lack of willingness (343 of 556, 61.7%). Almost all (142 of 156, 91%) health professionals reported lack of funding and resources as barriers to provision of continence services. Many young people (14 of 19, 74%) were unhappy using toilet facilities while out and about. Conclusions Perceptions that children lack understanding and willingness, and inadequate facilities impact the implementation of toileting interventions for children and young people with neurodisability. Greater understanding is needed for children to learn developmentally appropriate toileting skills. Further research is recommended around availability and acceptability of interventions to ensure quality of life is unaffected

Feasibility of School-Based Identification of Children and Adolescents Experiencing, or At-risk of Developing, Mental Health Difficulties: a Systematic Review

Funder: Gates Cambridge Trust; doi: http://dx.doi.org/10.13039/501100005370Abstract: Under-identification of mental health difficulties (MHD) in children and young people contributes to the significant unmet need for mental health care. School-based programmes have the potential to improve identification rates. This systematic review aimed to determine the feasibility of various models of school-based identification of MHD. We conducted systematic searches in Medline, Embase, PsycINFO, ERIC, British Education Index, and ASSIA using terms for mental health combined with terms for school-based identification. We included studies that assessed feasibility of school-based identification of students in formal education aged 3–18 with MHD, symptomatology of MHD, or exposed to risks for MHD. Feasibility was defined in terms of (1) intervention fit, (2) cost and resource implications, (3) intervention complexity, flexibility, manualisation, and time concerns, and (4) adverse events. Thirty-three studies met inclusion criteria. The majority focused on behavioural and socioemotional problems or suicide risk, examined universal screening models, and used cross-sectional designs. In general, school-based programmes for identifying MHD aligned with schools’ priorities, but their appropriateness for students varied by condition. Time, resource, and cost concerns were the most common barriers to feasibility across models and conditions. The evidence base regarding feasibility is limited, and study heterogeneity prohibits definitive conclusions about the feasibility of different identification models. Education, health, and government agencies must determine how to allocate available resources to make the widespread adoption of school-based identification programmes more feasible. Furthermore, the definition and measurement of feasibility must be standardised to promote any future comparison between models and conditions
