24. Why so hyperintense? : identifying functional networks associated with cognition and mobility in cerebral small vessel disease

Author

Crockett, Rachel Alexandra

Abstract

White matter hyperintensities (WMH) are a prominent feature of cerebral small vessel disease and are associated with cognitive and mobility impairment. These deficits may be caused by the disruption of large-scale functional networks due to the presence of WMHs. However, knowledge regarding the relevance of these lesions on functional networks remains inconclusive. In this thesis I used lesion network mapping to: 1) investigate the functional connectivity specifically associated with WMHs; and 2) determine whether WMH-related disruption to major functional networks is associated with impairments in cognition and mobility. In addition, physical activity (PA) is a possible countermeasure to reduce both WMHs and falls risk. However, no study has yet investigated whether PA attenuates the association between WMHs, falls risk, and cognition. I conducted a secondary cross-sectional analysis to investigate whether PA moderates the association between WMH volume, falls risk, and cognition. Finally, resistance training (RT) is a promising lifestyle intervention to reduce WMH progression, improve executive functions, and reduce falls. However, the underlying neurobiological process by which RT improves executive functions and falls risk remain unclear. Thus, I conducted an exploratory analyses of a randomized controlled trial to: 1) identify whether RT is able to mitigate WMH-related network disruption; and 2) determine whether changes in network disruption are associated with changes in cognition and falls risk. My research showed that WMH-related disruption to the sensorimotor, and ventral attention network was associated with poorer global cognition and postural sway, while disruption to the dorsal attention network was associated with increased falls risk. I showed that PA moderates the association between WMHs and falls risk and that 12 months of twice-weekly RT slowed WMH-related disruption to the sensorimotor, dorsal attention, and ventral attention networks. Reduced disruption to the dorsal and ventral attention networks was associated with improved executive functions and reduced falls risk respectively. The findings from this thesis highlight the functional networks disrupted by WMHs that may underlie the cognitive impairment and increased falls risk evident in older adults with cerebral small vessel disease. Further, interventions targeting disease progression should aim to increase physical activity, with a potential emphasis on RT.

Abstract

Abstract Background The behavioural impact of pharmacogenomics is untested; informing smokers of genetic test results for responsiveness to smoking cessation medication may increase adherence to this medication. The objective of this trial is to estimate the impact upon adherence to nicotine replacement therapy (NRT) of informing smokers that their oral dose of NRT has been tailored to a DNA analysis. Hypotheses to be tested are as follows: IAdherence to NRT is greater among smokers informed that their oral dose of NRT is tailored to an analysis of DNA (genotype), compared to one tailored to nicotine dependence questionnaire score (phenotype). II Amongst smokers who fail to quit at six months, motivation to make another quit attempt is lower when informed that their oral dose of NRT was tailored to genotype rather than phenotype. Methods/Design An open label, parallel groups randomised trial in which 630 adult smokers (smoking 10 or more cigarettes daily) using National Health Service (NHS) stop smoking services in primary care are randomly allocated to one of two groups: i. NRT oral dose tailored by DNA analysis (OPRM1 gene) (genotype), or ii. NRT oral dose tailored by nicotine dependence questionnaire score (phenotype) The primary outcome is proportion of prescribed NRT consumed in the first 28 days following an initial quit attempt, with the secondary outcome being motivation to make another quit attempt, amongst smokers not abstinent at six months. Other outcomes include adherence to NRT in the first seven days and biochemically validated smoking abstinence at six months. The primary outcome will be collected on 630 smokers allowing sufficient power to detect a 7.5% difference in mean proportion of NRT consumed using a two-tailed test at the 5% level of significance between groups. The proportion of all NRT consumed in the first four weeks of quitting will be compared between arms using an independent samples t-test and by estimating the 95% confidence interval for observed between-arm difference in mean NRT consumption (Hypothesis I). Motivation to make another quit attempt will be compared between arms in those failing to quit by six months (Hypothesis II). Discussion This is the first clinical trial evaluating the behavioural impact on adherence of prescribing medication using genetic rather than phenotypic information. Specific issues regarding the choice of design for trials of interventions of this kind are discussed. Trial details Funder: Medical Research Council (MRC) Grant number: G0500274 ISRCTN: 14352545 Date trial stated: June 2007 Expected end date: December 2009 Expected reporting date: December 2010

50. NUTRITIONAL LABELLING TO PROMOTE HEALTHIER FOOD PURCHASING AND CONSUMPTION: PRELIMINARY RESULTS OF A SYSTEMATIC LITERATURE REVIEW

Author

Subjects
digestive, oral, and skin physiology
Abstract

This is the protocol for a review and there is no abstract. The objectives are as follows: The primary objective of this review is to assess whether nutritional labelling of foods in comparison to the same foods presented either without a label or with an incomplete label promotes: 1. healthier food purchasing behaviour from: a) restaurants, b) food shops, c) vending machines; or 2. healthier food consumption behaviour. The secondary objective of the review is to explore possible modifiers of the effect of nutritional labelling on purchasing and consumption (described in more detail under ’Types of outcome’).
