Plain language summary
Lung cancer treatment initiates a deconditioning storm that further reduces the capacity to deliver and utilize oxygen and metabolic substrates during exercise, contributing to poor cardiorespiratory fitness. The main aim of this study was to assess the impact of aerobic exercise with inspiratory and expiratory muscle training on cardiovascular fitness and respiratory muscle dysfunction in non-small cell lung cancer patients. The study is a two-centre, prospective, single-blind, pilot randomized controlled trial. The eligible patients were randomly assigned to the exercise (n=16) or control groups (n=21). Study results showed strong improvement in respiratory muscle strength and exercise capacity following high-intensity inspiratory and expiratory muscle training. Authors conclude that structured and supervised exercise interventions should be recommended to patients with lung cancer.
Abstract
BACKGROUND Lung resection surgery further decreases exercise capacity and negatively affects respiratory muscle function in patients with non-small cell lung cancer (NSCLC). The best design for exercise interventions in these patients has not been determined yet. AIM: To assess the impact of aerobic exercise and high-intensity respiratory muscle training on patient outcomes following lung cancer resection surgery. DESIGN Prospective, single-blind, pilot randomized controlled trial. SETTING Outpatient cardiopulmonary rehabilitation unit of two university hospitals. POPULATION Thirty-seven patients with NSCLC after tumor resection. METHODS Patients were randomly assigned to exercise training or usual post-operative care. The training program consisted of aerobic exercises and high-intensity respiratory muscle training (24 supervised sessions, 3 per week, 8 weeks). Primary outcome was exercise capacity assessed with peak oxygen uptake (VO2peak) during cardiopulmonary exercise test. Secondary outcomes included changes in respiratory muscle strength, levels of serum insulin growth factor I (IGF-I) and IGF binding protein 3 (IGFBP-3), and quality of life assessed with the European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) questionnaire. RESULTS The 8-week training program was associated with significant improvement in VO2peak (2.13 mL/Kg/min [95%CI 0.06 to 4.20]), maximal inspiratory and expiratory pressures (18.96 cmH2O [95% CI 2.7 to 24.1] and 18.58 cmH2O [95% CI 4.0 to 33.1], respectively) and IGFBP-3 (0.61 µg/mL [%95 CI 0.1 to 1.12]). No significant differences were observed in the EORTC QLQ-C30. CONCLUSIONS An 8-week exercise program consisting of aerobic exercise and high-intensity respiratory muscle training improved exercise capacity, respiratory muscle strength, and serum IGFBP-3 levels in NSCLC patients after lung resection. There was no impact on the other outcomes assessed. CLINICAL REHABILITATION IMPACT A combination of aerobic exercise and respiratory muscle training could be included in the rehabilitation program of deconditioned patients with NSCLC after lung resection surgery.

Abstract
BACKGROUNDS & AIMS The European Society of Clinical Nutrition and Metabolism (ESPEN) consensus definition of malnutrition has been applied in hospitalized older diabetics and middle-aged patients, geriatric outpatients, and healthy elderly and young individuals. In a post-acute care setting, our aim was to assess malnutrition (ESPEN definition) and determine its relationship with sarcopenia in older in-patients deconditioned due to an acute process. METHODS Eighty-eight in-patients aged ≥70 years with body mass index (BMI) <30 kg/m2 were included (84.1 years old; 62% women) and screened for malnutrition risk using biochemical markers and Mini-Nutritional Assessment-Short Form (MNA-SF). The ESPEN definition was applied: 1) BMI <18.5 kg/m2 or 2) unintentional weight loss plus a) low BMI or b) low fat-free mass index (FFMI). European Working Group on Sarcopenia in Older People (EWGSOP) criteria were also applied. RESULTS Unintentional weight loss occurred in 27 (30.7%) of 88 in-patients considered "at risk" by MNA-SF. Malnutrition prevalence was 4.5%, 7.9%, and 17% using ESPEN definitions 1, 2a, and 2b, respectively; 19.3% were malnourished. Prevalence of sarcopenia was 37.5%, of which 90.9% fulfilled ESPEN malnutrition criteria, a significant association (p = 0.02). No differences in biochemical markers were observed between patients with or without malnutrition or sarcopenia. CONCLUSIONS ESPEN criteria constitute an appropriate tool to establish a malnutrition diagnosis in post-acute care. Sarcopenia, as defined by EWGSOP, was present in 37.5% of patients, of which 90.9% fulfilled ESPEN criteria; therefore, malnutrition was significantly related to sarcopenia. Additional work is needed to determine further implications of the ESPEN consensus definition.
