RESUMEN
BACKGROUND: Chest physiotherapy plays a crucial role in the treatment of COPD, although the optimal techniques for airway clearance have not been definitively established. Among the different techniques, high-frequency chest wall oscillation (HFCWO) has gained attention for its potential to create a widespread lung percussion, facilitating the removal of secretions and potentially clearing the peripheral bronchial tree. This study aims to assess the effectiveness of a novel "focused pulse" HFCWO in patients with moderate to severe COPD. METHODS: Sixty patients were randomized to three groups: a group treated with the PEP technique, a group with "focused pulse "HFCWO" and a group with pharmacological therapy alone (control group). The primary outcomes were changes in respiratory function parameters, changes in dyspnea and quality of life scores as well as daily life activity and health status assessment. The secondary outcomes were the number of exacerbations and the number of practitioner or emergency department (ED) visits after 1, 3, and 6 months. RESULTS: Sixty patients concluded the study with 20 patients allocated to each group. The two devices improved respiratory function tests, quality of life and health scores and dyspnea compared to the control group. Maximal expiratory pressure and diffusing lung carbon oxide were significantly improved in the focused pulse HFCWO group compared to the PEP group. Only pulse-focused HFCWO showed a statistically significant lower number of exacerbations and visits to ED or practitioner compared to the control group. CONCLUSIONS: The focused pulse HFCWO technique improves daily life activities and lung function in patients with stable COPD. The device demonstrated significantly greater effectiveness in lowering COPD exacerbations as well as visits to ED or practitioner.

BACKGROUND: Several technological advances and digital solutions have been proposed in the recent years to face the emerging need for tele-monitoring older adults with Chronic Obstructive Pulmonary Disease (COPD). However, several challenges have negatively influenced an evidence-based approach to improve Health-Related Quality of Life (HR-QoL) in these patients. AIM: To assess the effects of tele-monitoring devices on HR-QoL in older adults with COPD. METHODS: On November 11, 2022, PubMed, Scopus, Web of Science, and Cochrane were systematically searched for randomized controlled trials (RCTs) consistent with the following PICO model: older people with COPD as participants, tele-monitoring devices as intervention, any comparator, and HR-QoL as the primary outcome. Functional outcomes, sanitary costs, safety, and feasibility were considered secondary outcomes. The quality assessment was performed in accordance with the Jadad scale. RESULTS: A total of 1845 records were identified and screened for eligibility. As a result, 5 RCTs assessing 584 patients (423 males and 161 females) were included in the systematic review. Tele-monitoring devices were ASTRI telecare system, WeChat social media, Pedometer, SweetAge monitoring system, and CHROMED monitoring platform. No significant improvements in terms of HR-QoL were reported in the included studies. However, positive effects were shown in terms of the number of respiratory events and hospitalization in patients telemonitored by SweetAge system and CHROMED platform. DISCUSSION: Although a little evidence supports the role of tele-monitoring devices in improving HR-QoL in older patients, positive effects were reported in COPD exacerbation consequences and functional outcomes. CONCLUSION: Tele-monitoring solutions might be considered as sustainable strategies to implement HR-QoL in the long-term management of older patients with COPD.

BACKGROUND: Despite the fact that weaning from mechanical ventilation (MV) is one of the main rehabilitation goals in patients with spinal cord injury (SCI), controversies are still open about the optimal rehabilitation approach. OBJECTIVE: This systematic review aimed at characterizing the rehabilitation interventions currently available to optimize weaning from MV in SCI patients. METHODS: On April 12nd, 2022, a systematic literature search was performed in PubMed, Scopus, Web of Science, Cochrane, and PEDro, identifying studies assessing MV patients with SCI undergoing pulmonary rehabilitation. The primary outcomes were weaning duration, MV duration, and weaning success rate. Secondary outcomes were pulmonary function, extubation or decannulation time, length of stay, and safety. RESULTS: Out of 413 records, 14 studies were included (2 randomized controlled trials, 7 observational studies, and 5 case reports). Most of the studies assessed a comprehensive rehabilitation approach, including high tidal volume ventilation, positioning, mechanical lung recruitment maneuvers, secretion management strategies, respiratory muscle training, and electrical stimulation. CONCLUSION: Our findings suggested that a comprehensive rehabilitation intervention might have a role in reducing MV duration in patients with SCI. Further studies are needed to better characterize the optimal rehabilitation strategies for enhancing functional recovery of patients with SCI.

Chronic obstructive pulmonary disease (COPD) is a burdensome condition affecting a growing number of people worldwide, frequently related to major comorbidities and functional impairment. In these patients, several factors might have a role in promoting both bone and muscle loss, including systemic inflammation, corticosteroid therapies, sedentary behaviours, deconditioning, malnutrition, smoking habits, and alcohol consumption. On the other hand, bone and muscle tissues share several linkages from functional, embryological, and biochemical points of view. Osteosarcopenia has been recently defined by the coexistence of osteoporosis and sarcopenia, but the precise mechanisms underpinning osteosarcopenia in patients with COPD are still unknown. In this scenario, a deeper understanding of the molecular basis of osteosarcopenia might guide clinicians in a personalized approach integrating skeletal muscle health with the pulmonary rehabilitation framework in COPD. Taken together, our results summarized the currently available evidence about the multilevel interactions between osteosarcopenia and COPD to pave the way for a comprehensive approach targeting the most common risk factors of these pathological conditions. Further studies are needed to clarify the role of modern clinical strategies and telemedicine solutions to optimize healthcare delivery in patients with COPD, including osteopenia, osteoporosis, and sarcopenia screening in these subjects.

Osteoporosis is a highly prevalent condition affecting a growing number of patients affected by chronic obstructive pulmonary disease (COPD), with crucial implications for risk of fragility fractures, hospitalization, and mortality. Several risk factors have been identified to have a role in osteoporosis development in COPD patients, including corticosteroid therapy, systemic inflammation, smoke, physical activity levels, malnutrition, and sarcopenia. In this scenario, a personalized multitarget intervention focusing on the pathological mechanisms underpinning osteoporosis is mandatory to improve bone health in these frail patients. Specifically, physical exercise, nutritional approach, dietary supplements, and smoke cessation are the cornerstone of the lifestyle approach to osteoporosis in COPD patients, improving not only bone health but also physical performance and balance. On the other hand, pharmacological treatment should be considered for both the prevention and treatment of osteoporosis in patients at higher risk of fragility fractures. Despite these considerations, several barriers still affect the integration of a personalized approach to managing osteoporosis in COPD patients. However, digital innovation solutions and telemedicine might have a role in optimizing sustainable networking between hospital assistance and community settings to improve bone health and reduce sanitary costs of the long-term management of COPD patients with osteoporosis.
RESUMEN
Pulmonary rehabilitation (PR) is a well-established intervention supported by strong evidence that is used to treat patients affected by chronic respiratory diseases. However, several barriers still affect its spreading in rehabilitation clinical practices. Although chronic respiratory diseases are common age-related disorders, there is still a gap of knowledge regarding the implementation of sustainable strategies integrating PR in the rehabilitation management of frail patients at high risk of respiratory complications. Therefore, in the present study, we characterized the effects of PR in frail patients, highlighting the evidence supporting its role in improving the complex rehabilitative management of these patients. Moreover, we propose a novel organizational model promoting PR programs for frail patients in both inpatient and outpatient settings. Our model emphasizes the role of interdisciplinary care, specifically tailored to patients and environmental characteristics. In this scenario, cutting-edge technology and telemedicine solutions might be implemented as safe and sustainable strategies filling the gap between inpatient and outpatient settings. Future research should focus on large-scale sustainable interventions to improve the quality of life and global health of frail patients. Moreover, evidence-based therapeutic paths should be promoted and taught in training courses promoting multiprofessional PR knowledge to increase awareness and better address its delivery in frail patients.

BACKGROUND: To date, the mitochondrial function has been related to several pathways involved in the cellular aging process. Dietary supplements might have reciprocal and multilevel interactions with mitochondria network; however, no systematic review assessed the role of different nutraceuticals in mitochondria modification of healthy older adults. AIM: To assess the effects of different dietary supplements on mitochondria modifications in older adults. METHODS: On February 22, 2022, PubMed, Scopus, Web of Science, and Cochrane were systematically searched from inception for randomized controlled trials (RCTs). According to PICO model, we considered healthy older adults as participants, nutraceutical treatment as intervention, any treatment as comparator, mitochondrial modifications as outcome. Jadad scale was used for the quality assessment. RESULTS: Altogether, 8489 records were identified and screened until 6 studies were included. A total of 201 healthy older adults were included in the systematic review (mean age ranged from 67.0 ± 1.0 years to 76.0 ± 5.6 years). The dietary supplements assessed were sodium nitrite, N-3 polyunsaturated fatty acids, hydrogen-rich water, nicotinamide riboside, urolithin A, and whey protein powder. Positive effects were reported in terms of mitochondrial oxidative and antioxidant capacity, volume, bioenergetic capacity, and mitochondrial transcriptome based on the nutritional supplements. The quality assessment underlined that all the studies included were of good quality. DISCUSSION: Although dietary supplements might provide positive effects on mitochondria modifications, few studies are currently available in this field. CONCLUSION: Further studies are needed to better elucidate the reciprocal and multilevel interactions between nutraceuticals, mitochondria, and environmental stressors in healthy older adults.

Although botulinum toxin (BoNT) has been suggested as a treatment to counter neuropathic pain, no previous systematic reviews investigated the multidimensional effects of BoNT on pain relief and Health-Related Quality of Life (HR-QoL). The aim of this systematic review is to summarize the current evidence on the effectiveness of BoNT treatment for neuropathic pain, and to characterize its multidimensional effectiveness in order to guide physicians in clinical practice. Five databases were systematically searched up to 4 April 2022, to identify randomized controlled trials satisfying the following criteria: adults suffering from neuropathic pain, BoNT administration, any comparator, multidimensional assessment of pain as primary outcome, HR-QoL, physical function, anxiety and depression, and sleep quality as secondary outcomes. Twelve studies were included. The multidimensional pain scales used were short-form McGill Pain Questionnaire, Neuropathic pain scale, Neuropathic Pain Symptom Inventory, International SCI Pain Basic Data Set, West Haven-Yale Multidimensional Pain Inventory, Brief Pain Inventory, and Douleur Neuropathique 4. These scales highlighted the positive effects of BoNT administration. According to the Jadad scale, all the RCTs included were high-quality studies. BoNT administration might be effectively introduced in the comprehensive management of neuropathic pain. Further research should focus on optimal and cost-effective therapeutic protocols.

Mechanical ventilation (MV) is currently considered a life-saving intervention. However, growing evidence highlighted that prolonged MV significantly affects functional outcomes and length of stay. In this scenario, controversies are still open about the optimal rehabilitation strategies for improving MV duration in ICU patients. In addition, the efficacy of physiotherapy interventions in critical ill patients without positive history of chronic respiratory conditions is still debated. Therefore, this systematic review of randomized controlled trials (RCTs) with meta-analysis aimed at characterizing the efficacy of a comprehensive physiotherapy intervention in critically ill patients. PubMed, Scopus, and Web of Science databases were systematically searched up to October 22, 2021 to identify RCTs assessing acute patients mechanical ventilated in ICU setting undergoing a rehabilitative intervention. The primary outcomes were MV duration, extubation, and weaning time. The secondary outcomes were weaning successful rate, respiratory function, ICU discharge rate and length of stay. Out of 2503 records, 12 studies were included in the present work. The meta-analysis performed in 6 RCTs showed a significant improvement in terms of MV duration (overall effect size: -3.23 days; 95% CI = -5.79, -0.67, p = 0.01; Z = 2.47) in patients treated with a comprehensive physiotherapy intervention including early mobilization, positioning, airway clearance techniques, lung expansion and respiratory muscle training. The quality assessment underlined 9 studies (75%) of good quality and 3 studies of fair quality according to the PEDro scale. In conclusion, our results provided previously unavailable data about the role of comprehensive physiotherapy intervention in improving MV duration in critical ill patients without chronic respiratory conditions. Further studies are needed to better characterize the optimal combination of rehabilitation strategies enhancing the improvements in critical ill patients without chronic respiratory disorders.
RESUMEN
BACKGROUND: Early chest physiotherapy is recommended for patients with post-COVID syndrome to improve dyspnea, relieve anxiety, minimize disability, preserve lung function and improve Quality of Life. However, there is still no consensus on the best treatments to manage respiratory symptoms. We aimed to test a method based on a guided in/expiratory (I/E) modulation to treat the lung inhomogeneity. METHODS: Twenty patients with post-COVID syndrome and mild-to-moderate obstructive syndrome performed 3 15-min sessions/day using the I/E mode of the T-PEP®4 device (Medical Products Research Srl, Legnano, Milan, Italy), for 15 consecutive days. Lung function parameters, dyspnea, and Quality of Life scores, as well as exercise capacity were assessed before and after treatment. RESULTS: All patients concluded the treatment and showed significant improvements in symptoms (chest pain during deep inspiration, chest tightness, inability to yawn, fatigue during activities of daily living [ADL], desaturation ≥4% during ADL) and in health status (BCSS -1.75, P=0.0003; CAT -5.2, P=0.0001). Lung function (FVC +10.9%, P=0.0002; FEV

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is an incurable neurodegenerative disease affecting upper and lower motor neurons and resulting in progressive skeletal muscle weakness. Weak cough and difficulty in clearing secretions are often the cause of pulmonary infections and acute respiratory failure. Cough assistance is commonly used to provide support in coughing for patients with ALS. METHODS: This was a preliminary parallel randomized study comparing two cough-assist devices: one utilizing mechanical insufflation/exsufflation (MI/E) and expiratory flow accelerator (EFA) technology, the other utilizing only MI/E technology. The aim was to compare the effectiveness, safety and acceptability of the two devices. Thirty patients with ALS and similar severity and functional scale were enrolled. The primary outcome was the change in respiratory function, respiratory muscle function, gas exchange, and peak cough expiratory flow as an indicator of cough efficacy. Secondary outcomes were the number of exacerbations at 1, 6 and 12 months of treatment, and the patient-perceived comfort/distress related to the interventions together with the perceived efficacy of cough. RESULTS: Thirty subjects were recruited and randomized into the two groups (1:1 ratio). Primary outcomes : respiratory function parameters decreased over time in both groups, but significantly less in the Kalos group, as did the respiratory muscle strength parameters and peak cough flows. Gas exchanges decreased over time in both groups with no clinically relevant differences between groups. Secondary outcomes : there were no significant differences between groups regarding the number of exacerbations over time. No adverse events were reported. All participants, in both groups, reported a similar increase in perceived cough efficacy and there was no significant difference in comfort and distress between the two treatments. CONCLUSIONS: The cough-assist device with EFA technology performed better than a traditional MI/E device in ALS patients regarding respiratory function and cough efficacy, although number of exacerbations and acceptability of the two devices was similar. Following these promising preliminary results, further investigation is required in a larger cohort to confirm the superiority of EFA technology associated with a MI/E device.

In February 2020 the first COVID-19 case was reported in Italy and afterwards the virus started spreading rapidly, increasing dramatically the number of infected subjects. To face the pandemic outbreak, hospitals converted wards to assure COVID-19 patients' care and adopted measures to reduce virus diffusion. The aim of this study was to determine how many physiotherapists, in the Lombardy region, worked during pandemic, whether they continued their usual practice or were employed in COVID-19 wards and in which tasks they were involved. The survey was submitted online by the national professional order. The response rate was 11.79%. During the pandemic, 648 (53.9%) respondents interrupted their services. Less than 20% of the physiotherapists that continued working were assigned to COVID-19 wards with the role of physiotherapist. Only a small proportion of respondents had advanced skills in respiratory physiotherapy. Moreover, this study showed a limited involvement of physiotherapists inside the very acute and intense settings. In conclusion, this work revealed that, during COVID-19 pandemic, in the Lombardy region a small percentage of physiotherapists was employed in COVID-19 wards, mainly in post-acute context. Even though the response rate of this survey was very low, this study highlights the need to define and underline the role of physiotherapy in acute setting during emergency.

OBJECTIVES: Parkinson's disease (PD) causes dysfunction both to swallowing and to the cough mechanism. Oropharyngeal dysphagia is the main cause of pneumonia, due to silent aspiration of food and saliva. Pneumonia is the leading cause of death in PD. Different strategies exist to reduce the risk of inhalation and associated lung infections, but evidence of their efficacy is still unclear. The aim of this preliminary study was to investigate if adding an expiratory flow acceleration (EFA®) technique to standard therapy (ST) for dysphagia can reduce the incidence of bronchopulmonary infections and improve quality of life, respiratory function parameters, cough, and airways encumbrance perception. MATERIALS AND METHODS: Twenty-five patients with PD were randomized to two groups: ST vs. STâ¯+â¯EFA. Patients were re-assessed at 30, 180 and 360 days from start of treatment. The primary outcome was the incidence of respiratory exacerbations together with quality of life score (PDQ-39). Secondary outcomes were changes in respiratory function tests, cough capacity (CPEF), perceived health status (Euro-QOL-VAS), cough, and upper airways encumbrance perception evaluated by visual numeric scale (VNS). RESULTS: Twenty patients concluded the study (10 each group). Albeit the difference was not significant, less respiratory infections, symptoms, hospital admissions and medical visits were found in the study group. Furthermore, there was a significant difference in cough effectiveness measured with the peak cough expiratory flow (PCEF) and other spirometry parameters (FEV1, FVC), and also in specific and generic health-related quality of life measures (PDQ-39, Euro-QoL-VAS). CONCLUSION: The results of this preliminary study support the use of EFA® technology in Parkinson's patients with dysphagia to reduce the risk of respiratory complications. Nevertheless, further studies are needed in a larger, more representative sample to definitively confirm the usefulness of this technique in PD patients.

There is a need of consensus about the pulmonary rehabilitation (PR) in patients with COVID-19 after discharge from acute care. To facilitate the knowledge of the evidence and its translation into practice, we developed suggestions based on experts' opinion. A steering committee identified areas and questions sent to experts. Other international experts participated to a RAND Delphi method in reaching consensus and proposing further suggestions. Strong agreement in suggestions was defined when the mean agreement was >7 (1 = no agreement and 9 = maximal agreement). Panelists response rate was >95%. Twenty-three questions from 4 areas: Personnel protection equipment, phenotypes, assessments, interventions, were identified and experts answered with 121 suggestions, 119 of which received high level of concordance. The evidence-based suggestions provide the clinicians with current evidence and clinical experts opinion. This framework can be used to facilitate clinical decision making within the context of the individual patient. Further studies will evaluate the clinical usefulness of these suggestions.

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is associated with a higher risk of pulmonary infections. This risk not only negatively affects patients' quality of life but also increases social and health costs. Hence, there is a need for an effective rehabilitative treatment including airway clearance. The aim of this pilot study was to evaluate the efficacy of a new tool for bronchial clearance based on expiratory flow accelerator (EFA) technology compared with positive expiratory pressure (PEP) treatment. MATERIALS AND METHODS: Twenty stable patients with COPD, Global Initiative for Chronic Obstructive Lung Disease 3-4 stage, were enrolled and allocated to treatment with EFA or Bubble-PEP (BP) for 20 days during a pulmonary rehabilitation program. At baseline and the end of treatment, the following parameters were measured: arterial blood gases (ABG); respiratory function, including peak cough expiratory flow (PCEF), maximal inspiratory pressure (MIP), and maximal expiratory pressure exercise capacity using the 6-minute walk test (6MWT), dyspnea using the Medical Research Council scale, and quality of life using the St. George's Respiratory Questionnaire. RESULTS: Expiratory flow accelerator showed a significant pre- and post-improvement in ABG and a significantly greater improvement than BP in PCEF, MIP, and 6MWT post-treatment. CONCLUSION: Expiratory flow accelerator is a valid device compared with BP as an adjunctive therapy for the treatment of patients with severe COPD.
RESUMEN
INTRODUCTION/OBJECTIVES: The aim of our study was to assess the safety, efficacy and feasibility of an Expiratory Flow Accelerator (EFA) device, Free Aspire, in reducing the need for daily suctions in tracheostomised (TCS) patients. METHODS: Twenty-five patients (13 males, 12 females, aged 69.88 ± 9.06 years) were investigated. The number of superficial/deep suctions, shallows, arterial blood gas (ABG) analysis, perception of mucus encumbrance (Visual Numeric Scale, VNS) and adverse event were recorded for five days. On the first two days (T1-T2), suctioning was performed as usual, on the following three days (T3, T4, T5), patients were treated also with Free Aspire (20 min, 3 times a day). RESULTS/CONCLUSION: The use of the non-invasive device was associated with a decrease of total number of aspirations from T2 to T5 (8.48 ± 2.62 vs 4.48 ± 3.08, P = 0.0003). Total number of daily aspirations decreased over the five days (8.68 ± 3.64 vs 4.48 ± 3.08, P = 0.0009). Deep aspirations decreased from T1 to T5 (6.16 ± 3.53 vs 1.80 ± 1.50, P = 0.0001). ABG data confirmed that no significant side effects occurred. VNS score decreased from 7.03 ± 1.42 at T1 to 4.05 ± 1.80 at T5 (P < 0.0001). These data suggest that EFA may be useful for managing secretions in TCS patients, as it can reduce the number of daily suctions, particularly the deep ones, and may improve the perception of mucus encumbrance, without side effects. More studies are needed to confirm these data and to understand in which categories of TCS patients this device can be introduced.

A high variability in functional tests and activities used during the pulmonary rehabilitation has been observed in post-intensive care unit (ICU) patients, and the best battery of tests to adopt has not been described yet. We tested in patients admitted in a post-ICU Step Down Unit the ability to perform the more frequent functional volitional tests. The relations of each single volitional test with general disability and dyspnea at discharge were also evaluated. Ten volitional tests including: bedside spirometry test (ST: FEV1%, FVC%), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), Peak Expiratory Flow during Cough (PCEF), Quadriceps Muscle Strength (QMS), latissimus Dorsi and teres Major Strength (DMS), Brachial biceps Muscle Strength (BMS), effort tolerance measured by sit-to-stand test, Takahashi test and 6-Min Walking Test (6MWT), were evaluated in post-ICU patients at entry and discharge from in-hospital rehabilitation. General disability was assessed by Barthel Index, while dyspnea by Borg scale. At admission, >70% of subjects performed muscle strength test, while <25% performed respiratory and effort tolerance tests. At discharge, feasibility of spirometry, respiratory muscle strength and effort tolerance tests improved (all, p<0.001); 6MWT was the least feasible. At discharge, cardiorespiratory patients were more capable to perform tests compared to neurological ones. All outcome measures, with exception of FEV1%, and FVC%, were significantly related to the disability score. Peripheral muscle exercises showed the highest feasibility, spirometry and leg effort tolerance the lowest. Motor disability was explained mainly by the peripheral muscle strength. The study of non-volitional outcome measures and tests linked to a protocol-driven intervention should be performed in this specific population.

BACKGROUND: Airway clearance techniques include positive expiratory pressure, commonly used in our clinical practice, and a recently introduced temporary positive expiratory pressure device called UNIKO®. It is unclear which one provides the best benefit to patients. OBJECTIVES: The aim of this observational 4-year study was to retrospectively compare the efficacy of and specific indications for temporary positive expiratory pressure compared to positive expiratory pressure in a standard rehabilitation program. METHOD: We retrospectively collected data from 162 subjects (107 males, mean age 70±9 years, 97 with primary diagnosis of chronic obstructive pulmonary disease, 65 with bronchiectasis), 51 treated with temporary positive expiratory pressure and 111 with positive expiratory pressure. RESULTS: Subjects showed significant improvement in ratio of partial pressure arterial oxygen and fraction of inspired oxygen (p<0.001), forced vital capacity, forced expiratory volume in one second, peak expiratory flow, arterial oxygen saturation, and partial pressure arterial oxygen with no significant difference between positive expiratory pressure and temporary positive expiratory pressure groups apart from forced expiratory flow, which increased only in the positive expiratory pressure group. Evaluating specific subgroups, temporary positive expiratory pressure was more effective than positive expiratory pressure in improving gas transfer in subjects with emphysema and in those on oxygen therapy, as the effective supplement oxygen flow decreased significantly (p=0.034 and 0.046 respectively for temporary positive expiratory pressure vs. positive expiratory pressure). In subjects on mechanical ventilation, positive expiratory pressure was superior to temporary positive expiratory pressure in increasing forced expiratory flow (p=0.018). CONCLUSION: The physiological parameters of both groups improved significantly and similarly. Subgroup analysis suggests that temporary positive expiratory pressure could provide some advantage to subjects with emphysema and those on oxygen therapy, while positive expiratory pressure would benefit patients on mechanical ventilation. Randomized clinical trials are necessary to confirm our preliminary results indicating that different subgroups/phenotypes can benefit more from one type of treatment.

OBJECTIVE: To investigate the presence of dynamic hyperinflation after the Modified Shuttle Test (MST) and its relationship with lung function, exercise tolerance, and clinical symptoms in Cystic Fibrosis (CF). METHODS: Retrospective observational study. Subjects in clinically stable condition with a CF diagnosis based on a positive sweat test (chloride >60 mEq/L) and/or presence of two disease causing mutations, with available data on MST, spirometry, maximal voluntary ventilation, and inspiratory capacity manoeuvres were considered for the analysis. Breathing reserve was calculated and a threshold value of 0.7 was subsequently chosen as a value of pulmonary mechanical limit. Subjects were then categorized into two groups according to the change in the inspiratory capacity from rest to peak exercise. Unconditional logistic regression was used to estimate unadjusted odds ratios, 95% confidence intervals and P-values. RESULTS: Twenty-two subjects demonstrated evidence of dynamic hyperinflation during the MST. Thirteen out of 22 subjects were ventilatory limited during exercise including 5 of those without evidence of dynamic hyperinflation (P = 0.24). No combination of variables resulted in a parsimonious regression model. CONCLUSIONS: Dynamic hyperinflation is common in CF and it is not associated with traditionally defined ventilatory limitation parameters during the MST.
