IntroductionSubjectively experienced cognitive decline in older adults is an indicator of increased risk for dementia and is also associated with increased levels of anxiety symptoms. As anxiety is itself emerging as a risk factor for cognitive decline and dementia, the primary question of the present study is whether an 8-week mindfulness-based intervention can significantly reduce anxiety symptoms in patients with subjective cognitive decline (SCD). The secondary questions pertain to whether such changes extend to other domains of psychological, social, and biological functioning (including cognition, self-regulation, lifestyle, well-being and quality of life, sleep, and selected blood-based biomarkers) associated with mental health, older age, and risk for dementia.MethodsSCD-Well is a multicenter, observer-blinded, randomized, controlled, superiority trial, which is part of the Horizon 2020 European Union-funded “Medit-Ageing” project. SCD-Well compares an 8-week mindfulness- and compassion-based intervention specifically adapted for older adults with SCD with a validated 8-week health education program. Participants were recruited from memory clinics in four European sites (Cologne, Germany; London, United Kingdom; Barcelona, Spain; and Lyon, France) and randomized with a 1:1 allocation, stratified by site.ResultsThe primary outcome, change in anxiety symptoms, and secondary outcomes reflecting psychological, cognitive, social, and biological functioning are assessed at baseline, postintervention, and 4 months after the end of the intervention.DiscussionThe study will provide evidence on whether a mindfulness-based intervention can effect changes in anxiety and other risk factors for cognitive decline and dementia in older adults with SCD and will inform the establishment of intervention strategies targeted at improving mental health in older adults.
Summary Background It is widely believed that for allergic rhinitis and asthma, avoidance of specific triggers can improve symptom control. Whilst many children with asthma or rhinitis are sensitized to airborne allergens, primary care diagnostic and management decisions are often made without a detailed history of the allergic triggers or allergy testing. Thus, treatment decisions are empirical and allergen avoidance advice is either not given or, if given, not tailored to the child's sensitivities. Objective To ascertain whether allergy assessment and tailored advice in general practice enhances outcomes of children with asthma and rhinitis. Method Pragmatic RCT of allergy intervention (structured allergy history, skin prick testing and appropriate allergy avoidance advice) vs. usual care in children with asthma and/or rhinoconjunctivitis. A blinded observer assessed outcomes at 12 months. Main outcome measures were symptom scores and disease‐specific health‐related QoL. Secondary outcomes were healthcare utilization, days unable to pursue usual activities and self‐rated improvement. Results A total of 335 participants were randomized to formal allergy assessment or normal care. There were no differences in participants’ demographic or clinical characteristics at baseline (all P > 0.05). At 12 months, participants receiving the allergy intervention had fewer rhinitis symptoms (MD − 3.14, 95% CI − 6.01, − 0.81) and an improvement in QoL (MD − 0.50, 95% CI 0.32, 0.68). There were no significant changes in asthma symptoms, healthcare utilization or number of days unable to pursue usual activities. Conclusion Amongst children with known asthma and/or rhinitis in primary care, taking a structured allergy history with skin prick testing and tailored advice on allergy avoidance resulted in reduced symptoms of rhinitis and improved QoL.
Amongst adults with known asthma and/or rhinitis in primary care, taking a structured allergy history with skin prick tests and giving tailored advice on allergy avoidance made no difference to their symptoms, quality of life or lung function as measured twelve months later.
