Overview

Sinead completed her BSc in Sport Sciences at Brunel University in 2011. She then moved to the University of Exeter to study for a MSc in Sport and Exercise Medicine.

During her time as a Masters student, Sinead became very interested in the effects of dietary nitrate supplementation and lifestyle choices on cardiovascular health and exercise tolerance and went on to pursue a PhD in this area.

In 2017, Sinead joined the University of Exeter Medical School Primary Care department as a Postdoctoral Research Fellow where her research focuses on the detection and management of postural hypotension, hypertension and atrial fibrillation in primary care and the implementation of a home-based cardiac rehabilitation programme (REACH-HF) in the NHS.

Abstract
. Background: Postural hypotension (PH), the reduction in blood pressure when rising from sitting or lying to standing, is a risk factor for falls, cognitive decline and mortality. However, it is not often tested for in primary care despite these associated risks. PH prevalence varies according to definition, population, care setting and measurement method. The aim of this study was to determine the prevalence of PH across different care settings and disease subgroups.Methods: a systematic review, meta-analyses and meta-regression were undertaken. We searched Medline and Embase to October 2019 for studies based in primary, community or institutional care settings reporting PH prevalence. Data and study level demographics were extracted independently by two reviewers. Pooled estimates for mean prevalence of PH were compared between care settings and disease subgroups using random effects meta-analyses. Predictors of PH were explored using meta-regression. Quality assessment of included studies was undertaken using an adapted version of the Newcastle-Ottawa Scale.Results: 1816 studies were identified; 61 contributed to analyses. Pooled prevalences for PH using the consensus definition were 17% (95% CI, 14-20%) in the community, 19% (15-25%) in primary care and 31% (15-50%) in residential care or nursing homes (P=0.16 between groups). By condition, prevalences were 20% (16-24%) with hypertension, 21% (16-26%) with diabetes, 25% (18-33%) with Parkinson’s disease and 29% (25-33%) with dementia, compared to 14% (12-17%) without these conditions (P<0.01 between groups). Multivariable meta-regression modelling identified increasing age and diabetes as predictors of PH (P<0.01, P=0.13, respectively; R2=36%). PH prevalence was not affected by blood pressure measurement device (P=0.65) or sitting or supine resting position (P=0.24), however, when the definition of PH did not fulfil the consensus description, but fell within its parameters, prevalence was underestimated (P=0.01) irrespective of study quality (P=0.04).Conclusions: the prevalence of PH in populations relevant to primary care is substantial. The definition used is important when testing for PH. Our findings emphasise the importance of considering checking for PH, particularly in vulnerable populations, to enable interventions to manage it. These data should contribute to future guidelines relevant to the detection and treatment of postural hypotension.PROSPERO: CRD42017075423.

Getting evidence into clinical practice: protocol for evaluation of the implementation of a home-based cardiac rehabilitation programme for patients with heart failure. BMJ Open, 10(6), e036137-e036137.

IntroductionCardiac rehabilitation (CR) improves health-related quality of life and reduces hospital admissions. However, patients with heart failure (HF) often fail to attend centre-based CR programmes. Novel ways of delivering healthcare, such as home-based CR programmes, may improve uptake of CR. Rehabilitation EnAblement in CHronic Heart Failure (REACH-HF) is a new, effective and cost-effective home-based CR programme for people with HF. The aim of this prospective mixed-method implementation evaluation study is to assess the implementation of the REACH-HF CR programme in the UK National Health Service (NHS). The specific objectives are to (1) explore NHS staff perceptions of the barriers and facilitators to the implementation of REACH-HF, (2) assess the quality of delivery of the programme in real-life clinical settings, (3) consider the nature of any adaptation(s) made and how they might impact on intervention effectiveness and (4) compare real-world patient outcomes to those seen in a prior clinical trial.Methods and analysisREACH-HF will be rolled out in four NHS CR centres across the UK. Three healthcare professionals from each site will be trained to deliver the 12-week programme. In-depth qualitative interviews and focus groups will be conducted with approximately 24 NHS professionals involved in delivering or commissioning the programme. Consultations for 48 patients (12 per site) will be audio recorded and scored using an intervention fidelity checklist. Outcomes routinely recorded in the National Audit of Cardiac Rehabilitation will be analysed and compared with outcomes from a recent randomised controlled trial: the Minnesota Living with HF Questionnaire and exercise capacity (Incremental Shuttle Walk Test). Qualitative research findings will be mapped onto the Normalisation Process Theory framework and presented in the form of a narrative synthesis. Results of the study will inform national roll-out of REACH-HF.Ethics and disseminationThe study (IRAS 261723) has received ethics approval from the South Central (Hampshire B) Research Ethics Committee (19/SC/0304). Written informed consent will be obtained from all health professionals and patients participating in the study. The research team will ensure that the study is conducted in accordance with the Declaration of Helsinki, the Data Protection Act 2018, General Data Protection Regulations and in accordance with the Research Governance Framework for Health and Social Care (2005). Findings will be published in scientific peer-reviewed journals and presented at local, national and international meetings to publicise and explain the research methods and findings to key audiences to facilitate the further uptake of the REACH-HF intervention.Trial registrationISRCTN86234930.

We hypothesized that 4 wk of dietary nitrate supplementation would enhance exercise performance and muscle metabolic adaptations to sprint interval training (SIT). Thirty-six recreationally active subjects, matched on key variables at baseline, completed a series of exercise tests before and following a 4-wk period in which they were allocated to one of the following groups: 1) SIT and [Formula: see text]-depleted beetroot juice as a placebo (SIT+PL); 2) SIT and [Formula: see text]-rich beetroot juice (~13 mmol [Formula: see text]/day; SIT+BR); or 3) no training and [Formula: see text]-rich beetroot juice (NT+BR). During moderate-intensity exercise, pulmonary oxygen uptake was reduced by 4% following 4 wk of SIT+BR and NT+BR (P < 0.05) but not SIT+PL. The peak work rate attained during incremental exercise increased more in SIT+BR than in SIT+PL (P < 0.05) or NT+BR (P < 0.001). The reduction in muscle and blood [lactate] and the increase in muscle pH from preintervention to postintervention were greater at 3 min of severe-intensity exercise in SIT+BR compared with SIT+PL and NT+BR (P < 0.05). However, the change in severe-intensity exercise performance was not different between SIT+BR and SIT+PL (P > 0.05). The relative proportion of type IIx muscle fibers in the vastus lateralis muscle was reduced in SIT+BR only (P < 0.05). These findings suggest that BR supplementation may enhance some aspects of the physiological adaptations to SIT.NEW & NOTEWORTHY We investigated the influence of nitrate-rich and nitrate-depleted beetroot juice on the muscle metabolic and physiological adaptations to 4 wk of sprint interval training. Compared with placebo, dietary nitrate supplementation reduced the O2 cost of submaximal exercise, resulted in greater improvement in incremental (but not severe-intensity) exercise performance, and augmented some muscle metabolic adaptations to training. Nitrate supplementation may facilitate some of the physiological responses to sprint interval training.

Lactate or gas exchange threshold (GET) and critical power (CP) are closely associated with human exercise performance. We tested the hypothesis that the limit of tolerance (Tlim) during cycle exercise performed within the exercise intensity domains demarcated by GET and CP is linked to discrete muscle metabolic and neuromuscular responses. Eleven men performed a ramp incremental exercise test, 4-5 severe-intensity (SEV; >CP) constant-work-rate (CWR) tests until Tlim, a heavy-intensity (HVY; GET) CWR test until Tlim, and a moderate-intensity (MOD;. 0.05) muscle metabolic milieu (i.e. low pH and [PCr] and high [lactate]) was attained at Tlim (approximately 2-14 min) for all SEV exercise bouts. The muscle metabolic perturbation was greater at Tlim following SEV compared with HVY, and also following SEV and HVY compared with MOD (all P < 0.05). The normalized M-wave amplitude for the vastus lateralis (VL) muscle decreased to a similar extent following SEV (-38 ± 15%), HVY (-68 ± 24%), and MOD (-53 ± 29%), (P > 0.05). Neural drive to the VL increased during SEV (4 ± 4%; P < 0.05) but did not change during HVY or MOD (P > 0.05). During SEV and HVY, but not MOD, the rates of change in M-wave amplitude and neural drive were correlated with changes in muscle metabolic ([PCr], [lactate]) and blood ionic/acid-base status ([lactate], [K+]) (P < 0.05). The results of this study indicate that the metabolic and neuromuscular determinants of fatigue development differ according to the intensity domain in which the exercise is performed.NEW & NOTEWORTHY the gas exchange threshold and the critical power demarcate discrete exercise intensity domains. For the first time, we show that the limit of tolerance during whole-body exercise within these domains is characterized by distinct metabolic and neuromuscular responses. Fatigue development during exercise greater than critical power is associated with the attainment of consistent "limiting" values of muscle metabolites, whereas substrate availability and limitations to muscle activation may constrain performance at lower intensities.

McDonagh STJ (2018). Factors influencing the effects of dietary nitrate supplementation on nitric oxide biomarkers and blood pressure.

Ingestion of nitrate (NO3-) from natural sources can improve indices of cardiovascular health and exercise tolerance. The aim of this thesis was to determine the impact of dietary NO3- as a therapeutic aid when consumed amongst factors that might affect its efficacy such as antibacterial mouthwash, blood donation, different food forms and co-ingestion with alcoholic beverages. Young, healthy, normotensive individuals volunteered to participate in each experiment and undergo an array of physiological assessments. Chapter 4: Mouth rinsing with chlorhexidine and non-chlorhexidine mouthwash prior to consumption of concentrated NO3--rich beetroot juice (BR), over 6 days, blunted the rise in plasma nitrite concentration ([NO2-]) by 53 % and 29 % respectively, compared with control. Chlorhexidine mouthwash also elevated systolic (SBP) and mean arterial (MAP) blood pressure (BP) during treadmill walking. Chapter 5: Short-term BR ingestion lowered the oxygen (O2) cost of moderate-intensity exercise (by ~ 4 %), better preserved muscle oxygenation and attenuated the decline in incremental exercise tolerance (by 5 %) following whole blood donation. Chapter 6: an array of different NO3--rich vehicles, including BR, beetroot flapjack (BF), non-concentrated beetroot juice (BL) and beetroot crystals (BC), elevated salivary, plasma and urinary NO3- concentration ([NO3-]) and [NO2-] when compared with baseline and control, with the largest increases in plasma [NO2-] occurring in BF and BR. BR also reduced SBP (~5 mmHg) and MAP (~ 3-4 mmHg), and BF reduced diastolic BP (DBP; ~ 4 mmHg). Chapter 7: a high NO3- salad, accompanied by polyphenol-rich (NIT-RW) and -low (NIT-A) alcoholic beverages and a water control (NIT-CON) elevated salivary, plasma and urinary [NO3-] and [NO2-] compared with control (CON). SBP was reduced 2 h post consumption of NIT-RW (-4 mmHg), NIT-A (-3 mmHg) and NIT-CON (-2 mmHg) compared with CON. DBP and MAP were also lower in NIT-A, and more so in NIT-RW, compared with NIT-CON.
Overall, the findings in this thesis demonstrate the efficacy of naturally derived NO3- on NO metabolites, BP and exercise tolerance. The potential for such benefits to arise may be maximised if antibacterial mouthwash is avoided during supplementation and if NO3- is consumed as BR, BF or as a green leafy salad with or without an alcoholic beverage. It may also be suggested that NO3- ingestion can offset decrements in exercise tolerance following blood donation.
