BACKGROUND:This study examined the short-term reproducibility of non-invasive estimates of central and peripheral blood pressure and markers of central systolic loading (augmentation index [AIx; a measure of central systolic loading] and AIx75 [AIx standardised to 75 b·min-1 heart rate]) and the effect of posture and fasting state on these variables in patients with acute stroke. METHODS:Twenty-two acute stroke patients (72 ± 10y) had blood pressure measured using the SphygmoCor XCEL in supine and seated postures and whilst fasted and non-fasted. RESULTS:Acceptable short-term reproducibility (ICC >0.75) was reported for all peripheral and central variables in all conditions (ICC = 0.77-0.90) and for AIx and AIx75 in both fasted postures (ICC = 0.78-0.81). Food consumption significantly lowered all blood pressures (p

Objectives To assess physical activity (PA), mental health and well-being of adults in the United Kingdom (UK), Ireland, New Zealand and Australia during the initial stages of National governments’ Coronavirus disease (COVID-19) containment responses. Design Observational, cross-sectional. Methods An online survey was disseminated to adults (n = 8,425; 44.5 ± 14.8y) residing in the UK, Ireland, New Zealand and Australia within the first 2-6 weeks of government-mandated COVID-19 restrictions. Main outcome measures included: Stages of Change scale for exercise behaviour change; International Physical Activity Questionnaire (short-form); World Health Organisation-5 Well-being Index; and the Depression Anxiety and Stress Scale-9. Results Participants who reported a negative change in exercise behaviour from before initial COVID-19 restrictions to during the initial COVID-19 restrictions demonstrated poorer mental health and well-being compared to those demonstrating either a positive-or no change in their exercise behaviour (p < 0.001). Whilst women reported more positive changes in exercise behaviour, young people (18-29y) reported more negative changes (both p < 0.001). Individuals who had more positive exercise behaviours reported better mental health and well-being (p < 0.001). Although there were no differences in PA between countries, individuals in New Zealand reported better mental health and well-being (p < 0.001). Conclusion The initial COVID-19 restrictions have differentially impacted upon PA habits of individuals based upon their age and sex, and therefore have important implications for international policy and guideline recommendations. Public health interventions that encourage PA should target specific groups (e.g., men, young adults) who are most vulnerable to the negative effects of physical distancing and/or self-isolation.

Physical activity (PA) participation was substantially reduced at the start of the COVID-19 pandemic. The purpose of this study was to assess the association between PA, mental health, and wellbeing during and following the easing of COVID-19 restrictions in the United Kingdom (UK) and New Zealand (NZ). In this study, 3363 adults completed online surveys within 2–6 weeks of initial COVID-19 restrictions (April/May 2020) and once restrictions to human movement had been eased. Outcome measures included the International Physical Activity Questionnaire Short-Form, Depression Anxiety and Stress Scale-9 (mental health) and World Health Organisation-5 Wellbeing Index. There were no differences in PA, mental health or wellbeing between timepoints (p > 0.05). Individuals engaging in moderate or high volume of PA had significantly better mental health (−1.1 and −1.7 units, respectively) and wellbeing (11.4 and 18.6 units, respectively) than individuals who engaged in low PA (p < 0.001). Mental health was better once COVID-19 restrictions were eased (p < 0.001). NZ had better mental health and wellbeing than the UK (p < 0.001). Participation in moderate-to-high volumes of PA was associated with better mental health and wellbeing, both during and following periods of COVID-19 containment, compared to participation in low volumes of PA. Where applicable, during the current or future pandemic(s), moderate-to-high volumes of PA should be encouraged.

Participation in exercise and education programs following transient ischemic attack (TIA) or minor stroke may decrease cardiovascular disease risk. The purpose of this study was to assess the long-term effect (3.5 years) of an exercise and education program administered soon after TIA or minor stroke diagnosis on clinical outcome measures (stroke classification and number, patient deaths, hospital/emergency department admission) and cost implications obtained from standard hospital records. Hospital records were screened for 60 adults (male, n = 31; 71 ± 10 years), diagnosed with TIA or non-disabling stroke, who had previously been randomised and completed either an 8-week exercise and education program, or usual care control. Follow-up clinical outcomes and cost implications were obtained 3.5 ± 0.3 years post-exercise. Participants randomised to the exercise and education program had significantly fewer recurrent stroke/TIAs (n = 3 vs. n = 13, Cohen's d = 0.79) than the control group (P ≤ 0.003). Similar finding were reported for patient deaths (n = 0 vs. n = 4, d = 0.53), and hospital admissions (n = 48 vs. n = 102, d = 0.54), although these findings were only approaching statistical significance. The relative risk (mean; 95%CI) of death, stroke/TIAs and hospital admissions were 0.11 (0.01 to 1.98), 0.23 (0.07 to 0.72) and 0.79 (0.57 to 1.09), respectively. Hospital admission costs were significantly lower for the exercise group ($9041 ± 15,080 NZD [~$6000 ± 10,000 USD]) than the control group ($21,750 ± 22,973 NZD [~$14,000 ± 15,000 USD]) during the follow-up period (P 0.05, d = 0.69). The present study demonstrates the long-term patient benefit and economic importance of providing secondary prevention, exercise and education programs for patients with TIA and minor stroke.

Background This study examined the short-Term reproducibility of non-invasive estimates of central and peripheral blood pressure and markers of central systolic loading (augmentation index [AIx; a measure of central systolic loading] and AIx75 [AIx standardised to 75 b ·min-1 heart rate]) and the effect of posture and fasting state on these variables in patients with acute stroke. Methods Twenty-Two acute stroke patients (72 ± 10y) had blood pressure measured using the SphygmoCor XCEL in supine and seated postures and whilst fasted and non-fasted. Results Acceptable short-Term reproducibility (ICC >0.75) was reported for all peripheral and central variables in all conditions (ICC = 0.77-0.90) and for AIx and AIx75 in both fasted postures (ICC = 0.78-0.81). Food consumption significantly lowered all blood pressures (p 2; p = 0.20-0.55). The seated posture resulted in a significantly greater AIx than supine (p 2; p = 0.22). Fasting state had significant main effects on AIx and AIx75 (p 2; p = 0.14-0.22). Conslusions Oscillometric estimates of central blood pressure have high short-Term reproducibility in different postures and fasting states but markers of systolic load should be assessed whilst fasted. Fasting state has a large effect on central and peripheral blood pressures and on measures of systolic loading. It is important for clinicians to be aware of optimal assessment conditions without this impacting on patient wellbeing. Trial registration Clinical trial registry name: NCT02537652.

Background and aims The between-day reliability of oscillometric pulse wave analysis has been demonstrated in a young, healthy population but not in an older sample. This study examined the between-day reliability of the SphygmoCor XCEL in individuals over 50 years. As blood pressure is measured in a range of postures and fasting states (supine/seated, fasted/non-fasted), this study also investigated the effect of these variables on central blood pressure and central systolic loading. Methods Fifty-one adults (m = 21; age 57 ± 6.4 y) were tested on three mornings in supine and seated conditions and in fasted and non-fasted states. Data was analysed as a whole and for normotensive (n = 25) and hypertensive participants (n = 26). Results SphygmoCor XCEL demonstrated strong reliability in the whole sample for central systolic and diastolic blood pressures, augmentation index (AIx) and AIx75 (ICC = 0.77–0.95). Significant interaction effects were observed in central diastolic blood pressure, central pulse pressure, augmentation index (AIx) and AIx75 (p < 0.05; ηp 2 = 0.10–0.23). Fasting state had a greater influence on central pressures in a seated than supine posture, but a greater effect on central systolic loading measures in a supine posture. Conclusions The SphygmoCor XCEL is a reliable tool to assess central haemodynamic variables in an older population. It would be pertinent for clinicians and researchers to record central measures in a supine posture to minimise the effects of food consumption. Conversely, the assessment of central systolic loading should occur in a seated condition to minimise the influence of varying fasting states.

Background and objectives: As survival rates after incident stroke increase, the burden caused by secondary stroke and pressure placed on rehabilitation centers also rises. Lifestyle interventions have the potential to drive secondary-prevention treatments. Low-intensity interventions, such as heel raises, may offer a simple method of improving cardiovascular health and cognitive ability in chronic stroke. Here we present a protocol which attempts to determine whether a heel raise training program can improve markers of vascular health and cognitive function. Design: A randomized, controlled, crossover trial. Methods: Fifteen participants (> 3 months post-stroke diagnosis) will be randomly assigned to an intervention-first group (n = 8) or a control-first group (n = 7). In the intervention period, participants will complete 170 heel raises per day for 10 weeks. Heel raises will be completed in sets of ten, within a period of 170 minutes, from a seated position. In the control period, participants will go about their normal lives for 10 weeks. On completion of each program, participants will have a 4-week washout before commencing the alterative arm. Outcome measures: The primary outcomes (pre- and post-measures of peripheral and central blood pressure and pulse wave velocity) will be recorded, as these variables are strongly linked to vascular health after stroke. Secondary outcomes (cognitive function and maximal voluntary contractions) will be assessed using the Stroop task and electromyography respectively. A mixed-model analysis of variance will identify whether a heel raise intervention has a significant effect on the proposed primary and secondary outcome variables. Discussion: The potential improvements in vascular health may demonstrate that lower-limb heel raise exercise is a beneficial exercise stimulus for this population group. Ethics and dissemination: The protocol received ethical approval from the University of Winchester Ethics Committee (approval No. BLS/17/11) on November 30, 2017 and will be conducted in accordance with the Declaration of Helsinki, formulated by the World Medical Association. Written informed consent will be obtained from all participants. Recruitment began in June 2018. Analysis of the primary and secondary outcome measures will be completed in January 2019, and the study will finish in February 2019. Trial registration: The study was registered with ClinicalTrials.gov (NCT03423433) on February 6, 2018.
