Abstract
OBJECTIVE To determine the response to a pulmonary rehabilitation (PR) program and minimal important differences (MIDs) for the Short Physical Performance Battery (SPPB) subtests and SPPB summary score in patients with chronic obstructive pulmonary disease (COPD). DESIGN Retrospective analysis using distribution- and anchor-based methods. SETTING PR center in the Netherlands including a comprehensive 40-session 8-week inpatient or 14-week outpatient program. PARTICIPANTS A total of 632 patients with COPD (age, 65±8y; 50% male; forced expiratory volume in the first second=43% [interquartile range, 30%-60%] predicted). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Baseline and post-PR results of the SPPB, consisting of 3 balance standing tests, 4-meter gait speed (4MGS), and 5-repetition sit-to-stand (5STS). The chosen anchors were the 6-Minute Walk Test and COPD Assessment Test. Patients were stratified according to their SPPB summary scores into low-performance, moderate-performance, and high-performance groups. RESULTS 5STS (∆=-1.14 [-4.20 to -0.93]s) and SPPB summary score (∆=1 [0-2] points) improved after PR in patients with COPD. In patients with a low performance at baseline, balance tandem and 4MGS significantly increased as well. Based on distribution-based calculations, the MID estimates ranged between 2.19 and 6.33 seconds for 5STS and 0.83 to 0.96 points for SPPB summary score. CONCLUSIONS The 5STS and SPPB summary score are both responsive to PR in patients with COPD. The balance tandem test and 4MGS are only responsive to PR in patients with COPD with a low performance at baseline. Based on distribution-based calculations, an MID estimate of 1 point for the SPPB summary score is recommended in patients with COPD. Future research is needed to confirm MID estimates for SPPB in different centers.

[Pulmonary rehabilitation in the in-hospital and outpatient phases].
Carvajal Tello, N, Segura Ordoñez, A, Arias Balanta, AJ
Rehabilitacion. 2020;(3):191-199
Abstract
Pulmonary rehabilitation programmes aim to improve aerobic capacity and enhance quality of life in patients with chronic pulmonary disease, facilitating their participation and integration in different areas and activities of daily living, through the prescription and performance of physical exercise, as well as education on risk factors and healthy living. In multidisciplinary processes, various health professionals work together to support patients through the rehabilitation process, guiding lifestyle changes to improve their level of physical activity, nutritional factors, smoking cessation, diabetes management, medication adherence and weight loss, based on theories of behavioural change. The main objective of pulmonary rehabilitation programmes is to empower users in self-care and facilitate long-term management of chronic lung disease.

Abstract
This analysis extrapolates information from previous studies and experiences to bring physical medicine and rehabilitation perspective and intervention to the multidisciplinary treatment of COVID-19. The purpose of pulmonary rehabilitation in COVID-19 patients is to improve symptoms of dyspnea, relieve anxiety, reduce complications, minimize disability, preserve function, and improve quality of life. Pulmonary rehabilitation during the acute management of COVID-19 should be considered when possible and safe and may include nutrition, airway, posture, clearance technique, oxygen supplementation, breathing exercises, stretching, manual therapy, and physical activity. Given the possibility of long-term disability, outpatient posthospitalization pulmonary rehabilitation may be considered in all patients hospitalized with COVID-19.

Abstract
Cardiovascular diseases are frequently present in chronic obstructive pulmonary disease (COPD). Population-based studies found associations between retinal vessel diameters and cardiovascular health, but it is unknown whether this also applies to COPD patients. Therefore, we measured retinal vessel diameters in COPD patients and aimed to determine the association with cardiovascular risk factors, lung function, and functional outcomes. In addition, we investigated whether an exercise-based pulmonary rehabilitation (PR) program would change retinal vessel diameters, as a proxy for improved microvascular health. Demographics and clinical characteristics, including pulmonary function, exercise capacity, blood pressure, blood measurements and level of systemic inflammation were obtained from 246 patients during routine assessment before and after PR. Retinal vessel diameters were measured from digital retinal images. Older age and higher systolic blood pressure were associated with narrower retinal arterioles (β: -0.224; p = 0.042 and β: -0.136; p < 0.001, respectively). Older age, higher systolic blood pressure and lower level of systemic inflammation were associated with narrower retinal venules (β: -0.654; -0.229; and -13.767, respectively; p < 0.05). No associations were found between retinal vessel diameters and lung function parameters or functional outcomes. After PR, no significant changes in retinal venular or arteriolar diameter were found. To conclude, retinal vessel diameters of COPD patients were significantly associated with systolic blood pressure and systemic inflammation, whilst there was no evidence for an association with lung function parameters, functional outcomes or other cardiovascular risk factors. Furthermore, an exercise-based PR program did not affect retinal vessel diameter.

Concordant Evidence-Based Interventions in Cardiac and Pulmonary Rehabilitation Guidelines.
Smith, SMS, Chaudhary, K, Blackstock, F
Journal of cardiopulmonary rehabilitation and prevention. 2019;(1):9-18
Abstract
Chronic conditions such as chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) contribute to a significant burden to patients and many experience a reduction in physical functioning, psychological health, and quality of life. The sentinel symptom for COPD and CVD is breathlessness. Rehabilitation programs have been proven to reduce disease symptoms and increase levels of physical and psychological wellness. Pulmonary and cardiac rehabilitation programs have been recommended in international and national guidelines for managing COPD and CVD. Given that these programs seek to reduce breathlessness and improve the physical and psychological functioning of people with COPD and CVD, this review examines the concordant evidence-based interventions in rehabilitation guidelines. The findings of this review indicate that there was concordance in the program design, location of programs, types of health professionals involved in program delivery, assessments of patient at commencement and completion of program, and the delivery of educational topics with minor deviations that were related to disease-specific topics. Apart from disease-specific recommendations, the main divergence from rehabilitation guidelines was found to be dietary screening, inspiratory muscle training, and psychological assessments in evidence-based recommendations for cardiac and pulmonary programs.

Alternative interventions for obstructive sleep apnea.
Waters, T
Cleveland Clinic journal of medicine. 2019;(9 Suppl 1):34-41
Abstract
Positive airway pressure (PAP) therapy is the gold standard treatment for patients with obstructive sleep apnea (OSA) and has been shown to positively impact quality of life and cardiovascular outcomes. However, not all patients with OSA can use or tolerate PAP therapy. Alternative interventions to PAP include lifestyle measures, surgical interventions, hypoglossal nerve stimulation, oral appliance therapy, and expiratory PAP devices for OSA. While these alternative interventions may benefit patients and have demonstrated improvements in OSA and quality-of-life measures, the cardiovascular impact of these interventions is uncertain as data are limited.

Abstract
OBJECTIVE To determine the feasibility of a randomised controlled trial (RCT) of rhinothermy for the common cold. DESIGN Open label, randomised, controlled feasibility study. SETTING Single-centre research institute in New Zealand recruiting participants from the community. PARTICIPANTS 30 adult participants with symptoms of a common cold, presenting within 48 hours of the onset of symptoms. INTERVENTIONS Participants were randomly assigned 2:1 to receive either 35 L/min of 100% humidified air at 41°C via high flow nasal cannulae, 2 hours per day for up to 5 days (rhinothermy), or vitamin C 250 mg daily for 5 days (control). PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was the proportion of screened candidates who were randomised. Secondary outcomes included: proportion of randomised participants who completed the study; modified Jackson scores from randomisation to 10 days after initiation of randomised regimen; time until feeling 'a lot better' compared with study entry; time until resolution of symptoms or symptom score at 10 days postrandomisation; proportion of organisms identified by PCR analysis of nasal swabs taken at baseline; the patterns of use of the rhinothermy device; estimated adherence of the control group; and rhinothermy device tolerability. RESULTS In all 30/79 (38%, 95% CI 27% to 50%) of potential participants screened for eligibility were randomised. Rhinothermy was well tolerated, and all randomised participants completed the study (100%, 95% CI 88% to 100%). The reduction from baseline in the modified Jackson score was greater with rhinothermy compared with control at days 2, 3, 4, 5 and 6, with the maximum difference at day 4 (-6.4, 95% CI -9.4 to -3.3). The substantial clinical benefit threshold for modified Jackson score was a 5-unit change. CONCLUSIONS This study shows that an RCT of rhinothermy compared with low-dose vitamin C in the treatment of the common cold is feasible. TRIAL REGISTRATION NUMBER ACTRN12616000470493; Results.

Abstract
BACKGROUND Despite effective pharmacotherapy, asthma continues to impair quality of life for most patients. Non-pharmacological approaches, including breathing retraining, are therefore of great interest to patients. However, clinicians rarely advocate breathing retraining and access to this intervention is restricted for most patients due to the limited availability of suitable physiotherapists and poor integration of breathing retraining into standard care. We aimed to assess the effectiveness of a digital self-guided breathing retraining intervention. METHODS In this randomised controlled trial, we recruited patients from 34 general practices in the UK. Eligibility criteria for patients with asthma were broad, comprising a physician diagnosis of asthma, age of 16-70 years, receipt of at least one anti-asthma medication in the previous year, and impaired asthma-related quality of life (Asthma Quality of Life Questionnaire [AQLQ] score of <5·5). We developed a self-guided intervention, which was delivered as a DVD plus a printed booklet (DVDB). Participants were randomly assigned to receive either the DVDB intervention, three face-to-face breathing retraining sessions, or standard care, in a 2:1:2 ratio, for 12 months. Randomisation was achieved using the Southampton Clinical Trials Unit telephone randomisation service by use of random number generators. The primary outcome was the AQLQ score in the intention-to-treat population at 12 months. The trial was powered to show equivalence between the two active intervention groups, and superiority of both intervention groups over usual care. Secondary outcomes included patient-reported and physiological measures of asthma control, patient acceptability, and health-care costs. This trial was registered with International Standard Randomised Controlled Trial Number registry, number ISRCTN88318003. FINDINGS Between Nov 5, 2012 and Jan 28, 2014, invitations to participate in the study were sent to 15 203 patients with general practitioner-diagnosed asthma, of whom 655 were recruited into the study. AQLQ scores at 12 months were significantly higher in the DVDB group (mean 5·40, SD 1·14) than in the usual care group (5·12, SD 1·17; adjusted mean difference 0·28, 95% CI 0·11 to 0·44), and in the face-to-face group (5·33, SD 1·06) than in the usual care group (adjusted mean difference 0·24, 95% CI 0·04 to 0·44); AQLQ scores were similar between the DVDB group and the face-to-face group (0·04, 95% CI -0·16 to 0·24). There were no significant differences between the randomisation groups in FEV1 or fraction of exhaled nitric oxide. 744 adverse events occurred in 272 patients: 101 (39%) of 261 patients in the DVDB group, 55 (42%) of 132 patients in the face-to-face group, and 132 (50%) of 262 in the usual care group, with patients reporting one or more event. 11 (4%) patients in the DVDB group, four (3%) patients in the face-to-face group, and 20 (8%) patients in the usual care group had a serious adverse event. INTERPRETATION Breathing retraining programmes improve quality of life in patients with incompletely controlled asthma despite having little effect on lung function or airway inflammation. Such programmes can be delivered conveniently and cost-effectively as a self-guided digital audiovisual programme, so might also reduce health-care costs.

Adjunct Therapies for Refractory Status Asthmaticus in Children.
Rehder, KJ
Respiratory care. 2017;(6):849-865
Abstract
Asthma exacerbation is a common reason for children to present to the emergency department. If primary therapies fail to halt the progression of an asthma flare, status asthmaticus often leads to hospital, and potentially ICU, admission. Following the initial administration of inhaled β agonists and systemic corticosteroids, a wide array of adjunct medical therapies may be used to treat status asthmaticus. Unfortunately, the data supporting the use of these adjunct therapies are often unclear, conflicting, or absent. This review will present the physiologic basis and summarize the supporting data for a host of adjunct therapies, including ipratropium, intravenous β agonists, methylxanthines, intravenous and inhaled magnesium, heliox (helium-oxygen mixture), ketamine, antibiotics, noninvasive ventilation, inhaled anesthetics, and extracorporeal membrane oxygenation. Finally, we present a suggested care map for escalating to these therapies in children with refractory status asthmaticus.

Abstract
BACKGROUND Heated, humidified air has long been used by people with the common cold. The theoretical basis is that steam may help congested mucus drain better and that heat may destroy the cold virus as it does in vitro. This is an update of a review last published in 2013. OBJECTIVES To assess the effects of inhaling heated water vapour (steam) in the treatment of the common cold by comparing symptoms, viral shedding, and nasal resistance. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (to February 2017), MEDLINE (1966 to 24 February 2017), Embase (1990 to 24 February 2017), and Current Contents (1998 to 24 February 2017). We also searched World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (8 March 2017) and ClinicalTrials.gov (8 March 2017) as well as reference lists of included studies. SELECTION CRITERIA Randomised controlled trials using heated water vapour in participants with the common cold or experimentally induced common cold were eligible for inclusion. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Three review authors independently screened titles and abstracts for inclusion of potential studies identified from the search. We recorded the selection process in sufficient detail to complete a PRISMA flow diagram. We used a data collection form for study characteristics and outcome data that was developed and used for previous versions of this review. Two review authors independently extracted data, and a third review author resolved any disagreements. We used Review Manager 5 software to analyse data. MAIN RESULTS We included six trials from five publications involving a total of 387 participants. We included no new studies in this 2017 update. The 'Risk of bias' assessment suggested an unclear risk of bias in the domain of randomisation and a low risk of bias in performance, detection, attrition, and reporting.It was uncertain whether heated, humidified air provides symptomatic relief for the common cold, as the fixed-effect analysis showed evidence of an effect (odds ratio (OR) 0.30, 95% confidence interval (CI) 0.16 to 0.56; 2 studies, 149 participants), but the random-effects analysis showed no significant difference in the results (OR 0.22, 95% CI 0.03 to 1.95). There is an argument for using either form of analysis. No studies demonstrated an exacerbation of clinical symptom scores. One study conducted in the USA demonstrated worsened nasal resistance, but an earlier Israeli study showed improvement. One study examined viral shedding in nasal washings, finding no significant difference between treatment and placebo groups (OR 0.47, 95% CI 0.04 to 5.19). As judged by the subjective response to therapy (i.e. therapy did not help), the number of participants reporting resolution of symptoms was not significantly higher in the heated humidified group (OR 0.58, 95% CI 0.28 to 1.18; 2 studies, 124 participants). There was significant heterogeneity in the effects of heated, humidified air on different outcomes, therefore we graded the quality of the evidence as low. Some studies reported minor adverse events (including discomfort or irritation of the nose). AUTHORS' CONCLUSIONS The current evidence does not show any benefits or harms from the use of heated, humidified air delivered via the RhinoTherm device for the treatment of the common cold. There is a need for more double-blind, randomised trials that include standardised treatment modalities.
