    Attenuating Muscle Mass Loss in Critical Illness: the Role of Nutrition and Exercise
    Chapple, L-AS ; Parry, SM ; Schaller, SJ (SPRINGER, 2022-08-31)
    PURPOSE OF REVIEW: Impaired recovery following an intensive care unit (ICU) admission is thought related to muscle wasting. Nutrition and physical activity are considered potential avenues to attenuate muscle wasting. The aim of this review was to present evidence for these interventions in attenuating muscle loss or improving strength and function. RECENT FINDINGS: Randomised controlled trials on the impact of nutrition or physical activity interventions in critically ill adult patients on muscle mass, strength or function are presented. No nutrition intervention has shown an effect on strength or function, and the effect on muscle mass is conflicting. RCTs on the effect of physical activity demonstrate conflicting results; yet, there is a signal for improved strength and function with higher levels of physical activity, particularly when commenced early. Further research is needed to elucidate the impact of nutrition and physical activity on muscle mass, strength and function, particularly in combination.

    Exercise in allogeneic bone marrow transplantation: a qualitative representation of the patient perspective
    Abo, S ; Parry, SM ; Ritchie, D ; Sgro, G ; Truong, D ; Denehy, L ; Granger, CL (SPRINGER, 2022-03-16)
    PURPOSE: Exercise is emerging as a vital aspect of care to alleviate the physical and psychosocial symptom burden associated with allogeneic bone marrow transplantation (BMT). Understanding the patient perspective regarding exercise is important to move towards implementation. This study aimed to characterise experiences and views regarding participation in an exercise program in adults receiving treatment for haematological disease with allogeneic BMT. METHODS: Individual semi-structured interviews were conducted with 35 participants from either an early- or late-commencing supervised group-based exercise program. Using an inductive, conventional approach to qualitative content analysis data were independently analysed by two researchers. RESULTS: Six major themes and 33 sub-themes were identified: this encompassed motivation, physical opportunity and capability to exercise; psychosocial effects of group-based exercise; experienced impact of participation in an exercise program; and intervention design considerations. Key barriers to exercise included symptom severity and fluctuating health and distance or difficult access to an exercise facility or equipment, whilst facilitators included encouragement from staff; peer support in the group-based setting; flexibility; education; and ability to measure change. CONCLUSION: This study highlights the importance of a flexible approach to exercise with consideration of individual symptoms and preferences. The perceived psychological impact of exercise should not be underestimated; future exercise programs should be designed in partnership with patients, with consideration of group-based activities to reduce social isolation if this is feasible in the treatment context. Intervention design should also acknowledge the individual's physical and psychological capability, opportunity and automatic and reflective motivation to direct and sustain exercise behaviours following BMT.

    Granger, CL ; Edbrooke, L ; Antippa, P ; Wright, G ; McDonald, CF ; Lamb, KE ; Irving, L ; Krishnasamy, M ; Abo, S ; Whish-Wilson, GA ; Truong, D ; Denehy, L ; Parry, SM (BMJ PUBLISHING GROUP, 2022-01-01)
    INTRODUCTION: Exercise is important in the postoperative management of lung cancer, yet no strong evidence exists for delivery of home-based programmes. Our feasibility (phase I) study established feasibility of a home-based exercise and self-management programme (the programme) delivered postoperatively. This efficacy (phase II) study aims to determine whether the programme, compared with usual care, is effective in improving physical function (primary outcome) in patients after lung cancer surgery. METHODS AND ANALYSIS: This will be a prospective, multisite, two-arm parallel 1:1, randomised controlled superiority trial with assessors blinded to group allocation. 112 participants scheduled for surgery for lung cancer will be recruited and randomised to usual care (no exercise programme) or, usual care plus the 12-week programme. The primary outcome is physical function measured with the EORTC QLQ c30 questionnaire. Secondary outcomes include health-related quality of life (HRQoL); exercise capacity; muscle strength; physical activity levels and patient reported outcomes. HRQoL and patient-reported outcomes will be measured to 12 months, and survival to 5 years. In a substudy, patient experience interviews will be conducted in a subgroup of intervention participants. ETHICS AND DISSEMINATION: Ethics approval was gained from all sites. Results will be submitted for publications in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ACTRN12617001283369.

    How is physical activity measured in lung cancer? A systematic review of outcome measures and their psychometric properties
    Edbrooke, L ; Denehy, L ; Parry, SM ; Astin, R ; Jack, S ; Granger, CL (WILEY, 2017-02-01)
    Physical activity (PA) levels are low in patients with lung cancer. Emerging evidence supports the use of interventions to increase PA in this population. We aimed to (1) identify and synthesize outcome measures which assess PA levels in patients with lung cancer and (2) to evaluate, synthesize and compare the psychometric properties of these measures. A systematic review of articles from searches was conducted of five electronic databases and personal records. Eligible studies were those which assessed PA using either performance-based or patient-reported measures. For aim 2, studies identified in aim 1 reporting on at least one psychometric property (validity, reliability, responsiveness or measurement error) were included. Two independent reviewers assessed eligibility and risk of bias with the COnsensus-based Standards for the selection of health status Measurement INstruments. Thirty-four studies using 21 different measures of PA were identified. Seventeen studies used performance-based measures. The Godin Leisure Time Exercise Questionnaire (GLTEQ) was the most frequently used patient-reported measure. Psychometric properties were reported for 13 of these measures and most frequently for movement sensors. Two studies reported on properties of the GLTEQ. Quality ratings for risk of bias were low. There is significant heterogeneity amongst studies regarding method of PA measurement along the lung cancer continuum. Greater consensus could be achieved by using a consensus approach such as a Delphi process. Future studies should include assessment of psychometric properties of the measurement tool being used. Currently, it is recommended where feasible, both performance-based and patient-reported measurements of PA should be undertaken.

    Associations between nutritional energy delivery, bioimpedance spectroscopy and functional outcomes in survivors of critical illness
    Fetterplace, K ; Beach, LJ ; MacIsaac, C ; Presneill, J ; Edbrooke, L ; Parry, SM ; Rechnitzer, T ; Curtis, R ; Berney, S ; Deane, AM ; Denehy, L (WILEY, 2019-12-01)
    BACKGROUND: Patients who survive critical illness frequently develop muscle weakness that can impact on quality of life; nutrition is potentially a modifiable risk factor. The present study aimed to explore the associations between cumulative energy deficits (using indirect calorimetry and estimated requirements), nutritional and functional outcomes. METHODS: A prospective single-centre observational study of 60 intensive care unit (ICU) patients, who were mechanically ventilated for at least 48 h, was conducted. Cumulative energy deficit was determined from artificial nutrition delivery compared to targets. Measurements included: (i) at recruitment and ICU discharge, weight, fat-free mass (bioimpedance spectroscopy) and malnutrition (Subjective Global Assessment score B/C); (ii) at awakening and ICU discharge, physical function (Physical Function in Intensive Care Test-scored) and muscle strength (Medical Research Council sum-score (MRC-SS). ICU-acquired weakness was defined as a MRC-SS score of less than 48/60. RESULTS: The median (interquartile range) cumulative energy deficit compared to the estimated targets up to ICU day 12 was 3648 (2514-5650) kcal. Adjusting for body mass index, age and severity of illness, cumulative energy deficit (per 1000 kcal) was independently associated with greater odds of ICU-acquired weakness [odds ratio (OR) = 2.1, 95% confidence interval (CI) = 1.4-3.3, P = 0.001] and malnutrition (OR = 1.9, 95% CI = 1.1-3.2, P = 0.02). In similar multivariable linear models, cumulative energy deficit was associated with reductions in fat-free mass (-1.3 kg; 95% CI = -2.4 to -0.2, P = 0.02) and physical function scores (-0.6 points; 95% CI = -0.9 to -0.3, P = 0.001). CONCLUSIONS: Cumulative energy deficit from artificial nutrition support was associated with reduced functional outcomes and greater loss of fat-free mass in ventilated ICU patients.

    Improving the delivery of physical activity services in lung cancer: A qualitative representation of the patient's perspective
    Granger, CL ; Parry, SM ; Edbrooke, L ; Abo, S ; Leggett, N ; Dwyer, M ; Denehy, L (WILEY, 2019-01-01)
    OBJECTIVE: To explore patient experiences of, and preferences for, physical activity after a lung cancer diagnosis. METHODS: This was a qualitative study involving seven patients who had been treated for lung cancer within the previous 2 years. Participants attended a focus group interview. Conventional content analysis methodology was used to analyse the text by two independent researchers. RESULTS: Eight major themes emerged from the data. These were as follows: the influence of past lifestyle and chronic disease; the perceived benefits of physical activity; using physical activity to facilitate return to activities of daily living; the impact of symptoms, capacity and motivation; family and peer support; access to services; health professionals; and enjoyment of different types of physical activity. Patients suggested several factors that could improve their healthcare experience. These include access to exercise professionals particularly after cancer treatment; access to information about physical activity in different formats; supervision from health professionals and peer support; and use of behaviour change strategies to achieve sustainable increases in physical activity. CONCLUSION: Our results should be considered in the improvement of lung cancer care pathways as we strive to implement physical activity services into routine clinical care.

    Early rehabilitation in critical care (eRiCC): functional electrical stimulation with cycling protocol for a randomised controlled trial
    Parry, SM ; Berney, S ; Koopman, R ; Bryant, A ; El-Ansary, D ; Puthucheary, Z ; Hart, N ; Warrillow, S ; Denehy, L (BMJ PUBLISHING GROUP, 2012-01-01)
    INTRODUCTION: Intensive care-acquired weakness is a common problem, leads to significant impairment in physical functioning and muscle strength, and is prevalent in individuals with sepsis. Early rehabilitation has been shown to be safe and feasible; however, commencement is often delayed due to a patient's inability to co-operate. An intervention that begins early in an intensive care unit (ICU) admission without the need for patient volition may be beneficial in attenuating muscle wasting. The eRiCC (early rehabilitation in critical care) trial will investigate the effectiveness of functional electrical stimulation-assisted cycling and cycling alone, compared to standard care, in individuals with sepsis. METHODS AND ANALYSIS: This is a single centre randomised controlled trial. Participants (n=80) aged ≥18 years, with a diagnosis of sepsis or severe sepsis, who are expected to be mechanically ventilated for ≥48 h and remain in the intensive care ≥4 days will be randomised within 72 h of admission to (1) standard care or (2) intervention where participants will receive functional electrical muscle stimulation-assisted supine cycling on one leg while the other leg undergoes cycling alone. Primary outcome measures include: muscle mass (quadriceps ultrasonography; bioelectrical impedance spectroscopy); muscle strength (Medical Research Council Scale; hand-held dynamometry) and physical function (Physical Function in Intensive Care Test; Functional Status Score in intensive care; 6 min walk test). Blinded outcome assessors will assess measures at baseline, weekly, at ICU discharge and acute hospital discharge. Secondary measures will be evaluated in a nested subgroup (n=20) and will consist of biochemical/histological analyses of collected muscle, urine and blood samples at baseline and at ICU discharge. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the relevant institution, and results will be published to inform clinical practice in the care of patients with sepsis to optimise rehabilitation and physical function outcomes.

    Functional outcomes in ICU - what should we be using? - an observational study
    Parry, SM ; Denehy, L ; Beach, LJ ; Berney, S ; Williamson, HC ; Granger, CL (BMC, 2015-03-29)
    INTRODUCTION: With growing awareness of the importance of rehabilitation, new measures are being developed specifically for use in the intensive care unit (ICU). There are currently 26 measures reported to assess function in ICU survivors. The Physical Function in Intensive care Test scored (PFIT-s) has established clinimetric properties. It is unknown how other functional measures perform in comparison to the PFIT-s or which functional measure may be the most clinically applicable for use within the ICU. The aims of this study were to determine (1) the criterion validity of the Functional Status Score for the ICU (FSS-ICU), ICU Mobility Scale (IMS) and Short Physical Performance Battery (SPPB) against the PFIT-s; (2) the construct validity of these tests against muscle strength; (3) predictive utility of these tests to predict discharge to home; and (4) the clinical applicability. This was a nested study within an ongoing controlled study and an observational study. METHODS: Sixty-six individuals were assessed at awakening and ICU discharge. Measures included: PFIT-s, FSS-ICU, IMS and SPPB. Bivariate relationships (Spearman's rank correlation coefficient) and predictive validity (logistic regression) were determined. Responsiveness (effect sizes); floor and ceiling effects; and minimal important differences were calculated. RESULTS: Mean ± SD PFIT-s at awakening was 4.7 ± 2.3 out of 10. On awakening a large positive relationship existed between PFIT-s and the other functional measures: FSS-ICU (rho = 0.87, p < 0.005), IMS (rho = 0.81, p < 0.005) and SPPB (rho = 0.70, p < 0.005). The PFIT-s had excellent construct validity (rho = 0.8, p < 0.005) and FSS-ICU (rho = 0.69, p < 0.005) and IMS (rho = 0.57, p < 0.005) had moderate construct validity with muscle strength. The PFIT-s and FSS-ICU had small floor/ceiling effects <11% at awakening and ICU discharge. The SPPB had a large floor effect at awakening (78%) and ICU discharge (56%). All tests demonstrated responsiveness; however highest effect size was seen in the PFIT-s (Cohen's d = 0.71). CONCLUSIONS: There is high criterion validity for other functional measures against the PFIT-s. The PFIT-s and FSS-ICU are promising functional measures and are recommended to measure function within the ICU. TRIAL REGISTRATION: Clinicaltrials.gov NCT02214823. Registered 7 August 2014).

    Which field walking test should be used to assess functional exercise capacity in lung cancer? an observational study
    Granger, CL ; Denehy, L ; Parry, SM ; Martin, J ; Dimitriadis, T ; Sorohan, M ; Irving, L (BMC, 2015-08-12)
    BACKGROUND: There is emerging evidence regarding the efficacy of exercise training to improve exercise capacity for individuals with non-small cell lung cancer (NSCLC). Cardiopulmonary exercise testing (CPET) is the gold standard measure of exercise capacity; however this laboratory test has limitations for use in research and clinical practice. Alternative field walking tests are the six-minute walk test (6MWT), incremental-shuttle walk test (ISWT) and endurance-shuttle walk test (ESWT); however there is limited information about their clinimetric properties in NSCLC. AIMS: In NSCLC to determine the 1) criterion validity of the 6MWT, ISWT and ESWT against CPET; 2) construct validity of the 6MWT, ISWT and ESWT against measures of function, strength, respiratory function and health-related quality of life (HRQoL); and 3) clinical applicability of the tests. METHODS: Twenty participants (40 % male, mean ± SD age 66.1 ± 6.5 years) with stage I-IIIb NSCLC completed the 6MWT, ISWT, ESWT and CPET within six months of treatment. Testing order was randomised. Additional measures included Eastern Cooperative Oncology Group Performance-Status (ECOG-PS, function), respiratory function, hand-grip dynamometry and HRQoL. Correlations and regression analyses were used to assess relationships. RESULTS: The ISWT demonstrated criterion validity with a moderate relationship between ISWT distance and CPET peak oxygen consumption (r = 0.61, p = 0.007). Relationships between CPET and six minute walk distance (6MWD) (r = 0.24, p = 0.329) or ESWT time (r = 0.02, p = 0.942) were poor. Moderate construct validity existed for the 6MWD and respiratory function (forced vital capacity % predicted r = 0.53, p = 0.019; forced expiratory volume in the first second % predicted r = 0.55, p = 0.015). There were no relationships between the walking tests and measures of function, strength or HRQoL. The ESWT had a ceiling effect with 18 % reaching maximum time. No floor effects were seen in the tests. The mean ± SD time required to perform the individual 6MWT, ISWT and ESWT was 12.8 ± 2.5, 14.7 ± 3.7 and 16.3 ± 5.0 min respectively; in comparison to CPET which was 51.2 ± 12.7 min. Only one assessor was required to perform all field walking tests and no adverse events occurred. CONCLUSIONS: The ISWT is a promising measure of functional exercise capacity in lung cancer. Findings need to be confirmed in a larger sample prior to translation into practice.
