Effects of resistance exercise and whey protein supplementation on cognitive function in older men:secondary analysis of a randomised, double-blind, placebo-controlled trial
No full textPURPOSE: Ageing is associated with cognitive decline. This study investigated the individual and combined effects of resistance exercise (RE) and whey protein supplementation (PRO) on cognitive function in older men.METHODS: In a pooled-groups analysis, 36 older men (age: 67 ± 4 years) were randomised to either RE (2 x/week; n = 18) or no exercise (NE; n = 18), and either PRO (2 × 25 g/d whey protein isolate; n = 18) or control (CON, 2 × 23.75 g maltodextrin/d; n = 18). A sub-analysis was also conducted between RE + CON (n = 9) and RE + PRO (n = 9). At baseline and 12 weeks, participants completed a battery of neuropsychological tests (CANTAB; Cambridge Cognition, UK) and neurobiological, inflammatory, salivary cortisol and insulin sensitivity biomarkers were quantified.RESULTS: PRO improved executive function z-score (+0.31 ± 0.08) greater than CON (+0.06 ± 0.08, P = 0.03) and there was a trend towards improved global cognitive function (P = 0.053). RE and RE + PRO did not improve any cognitive function domains (p ≥ 0.07). RE decreased tumor necrosis factor-alpha (P = 0.02) and interleukin-6 (P = 0.048) concentrations compared to NE, but changes in biomarkers did not correlate with changes in cognitive domains. Muscle strength (r = 0.34, P = 0.045) and physical function (ρ = 0.35-0.51, P < 0.05) outcomes positively correlated with cognitive function domains at baseline, but only Δskeletal muscle index correlated with Δepisodic memory (r = 0.34, P = 0.046) following the intervention.CONCLUSION: In older men, PRO improved cognitive function, most notably executive functioning. RE did not improve any cognitive function domains but did decrease biomarkers of systemic inflammation. No synergistic effects were observed.</p
Exploring Parsimonious Principles that Unify Active Portfolio Selection (II): Validation
No full textInvestor portfolio-selection behaviours remain inadequately integrated into a unified framework. We demonstrate that only two principles are necessary to span a comprehensive framework and unify diverse active portfolio-selection behaviours: (1) Subjective Allocation Rule (SAR)-based allocation and (2) Minimum Tracking Error (MTE)-guided mimicking. These principles leverage efficiency, value-adding, and cognition-friendly mechanisms to transform broader, more natural investor insights - whether quantitative or qualitative - into optimal portfolios aligned with their true intensions. Our empirical evidence reveals that incorporating investor subjectivity can enhance performance, outperforming traditional frameworks such as Markowitz’s. This paper, the second of two, focuses on the empirical evidence
Goal-oriented practices in youth mental health and wellbeing settings:A scoping review and thematic analysis of empirical evidence
No full textINTRODUCTION: Goal-oriented practices involve practitioners working collaboratively with clients to identify, develop and focus on objectives for the therapeutic work. It has been suggested that the key mechanism underpinning goal-oriented practices with young people is the development of epistemic trust via the foundation of open communication, along with shared decision-making: including young people in decisions about their care. However, goal-oriented work in practice is variable in scope and content, with no research consensus on what it entails, the mechanisms of change and reported outcomes.METHOD: This research aims to map the extent, range and nature of the evidence-base for goal-oriented practices, including gaps, through a synthesis of the available empirical evidence from the past 20 years. A scoping review of 9783 studies published from 2003 onwards was conducted.RESULTS: In total, 116 studies were identified for inclusion in the review, focusing on goal-oriented practices specifically related to the mental health and wellbeing of children and young people aged 0-18 (including caregivers as relevant). Alongside presentation of the key elements of the included studies, three themes were developed relating to the features of mental health and wellbeing goal-oriented practice in the contexts of the studies: Conceptual and Empirical Constructs of Goal-Oriented Practices, Quality and Making 'Good' Goals, and The Socio-Cultural Contexts of Goal-Oriented Practice.CONCLUSION: Several areas for future research are identified that will build on this evidence, and further understanding in this area. Work towards the development of best practice principles will move practice towards transparency in the understanding and delivery of goal-oriented practices.</p
Motivation, Engagement, and Performance in Two Distinct Modes of Brain Games: A Mixed Methods Study in Children
No full textRedeemed Christian Church of God in Britain – c.1980s to the present
No full textThis chapter examines the growth and ecclesial practices of the Redeemed Christian Church of God (RCCG) in Britain from the 1980s to the present. The RCCG was founded by Josiah Akindayomi in 1952. From a small, localised Pentecostal denomination in south-western Nigeria, it has become a movement of global significance with branches in over 180 nations.The chapter begins with an historical overview of the RCCG in Britain, setting this within the broader context of African church-planting in Britain. This is followed by an examination of the factors influencing the RCCG’s growth and shaping its ecclesial practices. Some social scientific explanations of African churches in Europe focus on their social function. This essay follows those studies that adopt a more holistic approach by taking account of sociological, theological and missiological factors behind their emergence and growth. By doing so, it provides a glimpse into the life of one of the most dynamic churches in Britain.<br/
Longitudinal Associations between Food Parenting Practices and Dietary Intake in preschool Children: The ToyBox Study
Get PDFIntroduction Food Parenting Practices (FPPs) include the practices parents use in the act of feeding their children, which may further influence their health. Objectives To assess associations between changes in FPPs (permissiveness, food availability, guided choices, water encouragement, rules and limits and the use of food as reward) over 1 year and dietary intake (water, energy-dense/nutrient-poor and nutrient-dense foods) at follow-up in 4- to 6-year-old preschool-aged children. Methods Longitudinal data from the control group of the ToyBox study, a cluster-randomized controlled intervention study, was used (NCT02116296). Multilevel ordinal logistic regression analyses including FPP as the independent variables and dietary intake as outcome. Results Nine hundred sixty-four parent-child dyads (50.5% boys and 95.0% mothers) were included. Limited changes on the use of FPPs were observed over time. Nevertheless, in boys, often having F&V at home was associated with higher F&V consumption (OR = 6.92 [1.58; 30.38]), and increasing home availability of F&V was directly associated with higher water consumption (OR = 7.62 [1.63; 35.62]). Also, not having sweets or salty snacks available at home was associated with lower consumption of desserts (OR = 4.34 [1.75; 10.75]). In girls, having F&V availability was associated with higher F&V consumption (OR = 6.72 [1.52; 29.70]) and lower salty snack consumption (OR = 3.26 [1.50; 7.10]) and never having soft drinks at home was associated with lower consumption of sweets (OR = 7.89 [6.32; 9.86]). Also, never being permissive about soft drink consumption was associated with lower soft drink consumption (OR = 4.09 [2.44; 6.85]). Conclusion Using favorable FPPs and avoiding the negative ones is prospectively associated with healthier dietary intake, especially of F&V, and less intake of soft drinks, desserts, and salty snacks.© 2024, Elsevier.
