Article Synopsis
  • Care homes are critical for research on interventions aimed at improving care quality, making it vital to choose suitable measures based on the specific population and context.
  • This scoping review analyzed 396 intervention studies from care homes published between 2015 and 2022, accounting for over 836,000 residents and evaluating various resident outcomes.
  • The findings highlighted a wide variety in outcome measures used, with many being assessed only once, indicating a need for standardized tools and methods that involve input from residents, families, and staff to enhance research effectiveness.

Evidence on the use of biomarkers to detect bladder cancer in the general population is scarce. This study aimed to systematically review evidence on the diagnostic performance of biomarkers which might be suitable for use in community and primary care settings [PROSPERO Registration: CRD42021258754]. Database searches on MEDLINE and EMBASE from January 2000 to May 2022 resulted in 4914 unique citations, 44 of which met inclusion criteria.

Background: Care homes are complex settings to undertake intervention research. Barriers to research implementation processes can threaten studies' validity, reducing the value to residents, staff, researchers and funders. We aimed to (i) identify and categorise contextual factors that may mediate outcomes of complex intervention studies in care homes and (ii) provide recommendations to minimise the risk of expensive research implementation failures.

Background: Mental health concerns in older adults are common, with increasing age-related risks to physical health, mobility and social isolation. Community-based approaches are a key focus of public health strategy in the UK, and may reduce the impact of these risks, protecting mental health and promoting wellbeing. We conducted a review of UK community-based interventions to understand the types of intervention studied and mental health/wellbeing impacts reported.

Background: Harmful alcohol consumption in older people has increased and effective approaches to understanding and addressing this societal concern are needed.

Methods: Systematic review of qualitative studies in older populations (55+ years) to identify barriers, facilitators or context of drinking in older people. Multiple databases (MEDLINE, EMBASE, PsycINFO, CINAHL, CENTRAL, Social Sciences Citation Index, York Centre for Reviews and Dissemination, Cochrane database and grey literature) were searched from 2000 to February 2017 for studies in English, from OECD countries using MeSH terms and text words relating to alcohol combined with older age terms.

Background: harmful alcohol consumption is reported to be increasing in older people. To intervene and reduce associated risks, evidence currently available needs to be identified.

Methods: two systematic reviews in older populations (55+ years): (1) Interventions to prevent or reduce excessive alcohol consumption; (2) Interventions as (1) also reporting cognitive and dementia outcomes.

Background: The promotion and maintenance of higher physical activity (PA) levels in the older population is an imperative for cognitive and healthy ageing but it is unclear what approaches are best suited to achieve this for the increasing number of older people living in the community. Effective policies should be informed by robust, multi-disciplinary and multi-dimensional evidence, which not only seeks what works, but in 'what context? In addition to evidence on the efficacy and effectiveness of PA for maintaining cognitive health, social contexts such as 'how do we actually get older people to partake in PA?' and 'how do we sustain that activity long-term?' also need highlighting. This review is part of a comprehensive evidence synthesis of preventive interventions in older age, with a focus on healthy behaviours to identify evidence gaps and inform policy relating to ageing well and cognitive health.

Background: Smoking, alcohol consumption, poor diet and low levels of physical activity significantly contribute to the burden of illness in developed countries. Whilst the links between specific and multiple risk behaviours and individual chronic conditions are well documented, the impact of these behaviours in mid-life across a range of later life outcomes has yet to be comprehensively assessed. This review aimed to provide an overview of behavioural risk factors in mid-life that are associated with successful ageing and the primary prevention or delay of disability, dementia, frailty and non-communicable chronic conditions.

Background: With an ageing population, there is an increasing societal impact of ill health in later life. People who adopt healthy behaviours are more likely to age successfully. To engage people in health promotion initiatives in mid-life, a good understanding is needed of why people do not undertake healthy behaviours or engage in unhealthy ones.

Background: Congenital cervical salivary duct fistulae are rare entities and can mimic branchial cleft fistulae. Ectopic salivary tissue associated with these pharyngocervical tracts may have malignant potential.

Methods And Results: We present a case report of a novel surgical approach and review of the literature.

Introduction: childhood obesity is a risk factor for many perioperative complications. Hypotension is a well described complication of general anaesthesia in both adults and children. This observational study compared the incidence of preincision hypotension (PIH) between children with high BMI and lean controls.
