ABSTRACT
Rationale: Diaphragm muscle weakness might underlie persistent exertional dyspnea, despite normal lung and cardiac function in individuals who were previously hospitalized for acute coronavirus disease (COVID-19) illness. Objectives: The authors sought, first, to determine the persistence and pathophysiological nature of diaphragm muscle weakness and its association with exertional dyspnea 2 years after hospitalization for COVID-19 and, second, to investigate the impact of inspiratory muscle training (IMT) on diaphragm and inspiratory muscle weakness and exertional dyspnea in individuals with long COVID. Methods: Approximately 2 years after hospitalization for COVID-19, 30 individuals (11 women, 19 men; median age, 58 years; interquartile range [IQR] = 51-63) underwent comprehensive (invasive) respiratory muscle assessment and evaluation of dyspnea. Eighteen with persistent diaphragm muscle weakness and exertional dyspnea were randomized to 6 weeks of IMT or sham training; assessments were repeated immediately after and 6 weeks after IMT completion. The primary endpoint was change in inspiratory muscle fatiguability immediately after IMT. Measurements and Main Results: At a median of 31 months (IQR = 23-32) after hospitalization, 21 of 30 individuals reported relevant persistent exertional dyspnea. Diaphragm muscle weakness on exertion and reduced diaphragm cortical activation were potentially related to exertional dyspnea. Compared with sham control, IMT improved diaphragm and inspiratory muscle function (sniff transdiaphragmatic pressure, 83 cm H2O [IQR = 75-91] vs. 100 cm H2O [IQR = 81-113], P = 0.02), inspiratory muscle fatiguability (time to task failure, 365 s [IQR = 284-701] vs. 983 s [IQR = 551-1,494], P = 0.05), diaphragm voluntary activation index (79% [IQR = 63-92] vs. 89% [IQR = 75-94], P = 0.03), and dyspnea (Borg score, 7 [IQR = 5.5-8] vs. 6 [IQR = 4-7], P = 0.03). Improvements persisted for 6 weeks after IMT completion. Conclusions: To the best of the authors' knowledge, this study is the first to identify a potential treatment for persisting exertional dyspnea in long COVID and provide a possible pathophysiological explanation for the treatment benefit. Clinical trial registered with www.clinicaltrials.gov (NCT04854863, NCT05582642).

BACKGROUND: In critically ill patients receiving mechanical ventilation, dyspnoea is frequent, severe and associated with an increased risk of neuropsychological sequelae. We evaluated the efficacy of sensory interventions targeting the brain rather than the respiratory system to relieve dyspnoea in mechanically ventilated patients. METHODS: Patients receiving mechanical ventilation for ≥48â h and reporting dyspnoea (unidimensional dyspnoea visual analogue scale (Dyspnoea-VAS)) first underwent increased pressure support and then, in random order, auditory stimulation (relaxing music versus pink noise) and air flux stimulation (facial versus lower limb). Treatment responses were assessed using Dyspnoea-VAS, the Multidimensional Dyspnea Profile and measures of the neural drive to breathe (airway occlusion pressure (P 0.1) and electromyography of inspiratory muscles). RESULTS: We included 46 patients (tracheotomy or intubation n=37; noninvasive ventilation n=9). Increasing pressure support decreased Dyspnoea-VAS by median 40â mm (p<0.001). Exposure to music decreased Dyspnoea-VAS compared with exposure to pink noise by median 40â mm (p<0.001). Exposure to facial air flux decreased Dyspnoea-VAS compared with limb air flux by median 30â mm (p<0.001). Increasing pressure support, but not music exposure and facial air flux, reduced P 0.1 by median 3.3â cmH2O (p<0.001). CONCLUSIONS: In mechanically ventilated patients, sensory interventions can modulate the processing of respiratory signals by the brain irrespective of the intensity of the neural drive to breathe. It should therefore be possible to alleviate dyspnoea without resorting to pharmacological interventions or having to infringe the constraints of mechanical ventilation lung protection strategies by increasing ventilatory support.

This statement outlines a review of the literature and current practice concerning the prevalence, clinical significance, diagnosis and management of dyspnoea in critically ill, mechanically ventilated adult patients. It covers the definition, pathophysiology, epidemiology, short- and middle-term impact, detection and quantification, and prevention and treatment of dyspnoea. It represents a collaboration of the European Respiratory Society and the European Society of Intensive Care Medicine. Dyspnoea ranks among the most distressing experiences that human beings can endure. Approximately 40% of patients undergoing invasive mechanical ventilation in the intensive care unit (ICU) report dyspnoea, with an average intensity of 45â mm on a visual analogue scale from 0 to 100â mm. Although it shares many similarities with pain, dyspnoea can be far worse than pain in that it summons a primal fear response. As such, it merits universal and specific consideration. Dyspnoea must be identified, prevented and relieved in every patient. In the ICU, mechanically ventilated patients are at high risk of experiencing breathing difficulties because of their physiological status and, in some instances, because of mechanical ventilation itself. At the same time, mechanically ventilated patients have barriers to signalling their distress. Addressing this major clinical challenge mandates teaching and training, and involves ICU caregivers and patients. This is even more important because, as opposed to pain which has become a universal healthcare concern, very little attention has been paid to the identification and management of respiratory suffering in mechanically ventilated ICU patients.

BACKGROUND: Dyspnea conveys an upsetting or distressing experience of breathing awareness. It heavily weighs on chronic respiratory disease patients, particularly when it persists despite maximal treatment of causative abnormalities. The physical, psychological and social impacts of persistent dyspnea are ill-appreciated by others. This invisibility constitutes a social barrier and impedes access to care. This study aimed to better understand dyspnea invisibility in patients with chronic obstructive pulmonary disease (COPD) through quantitative discourse analysis. METHODS: We conducted a lexicometric analysis (lemmatization, descending hierarchical classification, multicomponent analysis, similarity analysis) of 11 patients' discourses (6 men, severe COPD; immediate postexacerbation rehabilitation) to identify semantic classes and communities, which we then confronted with themes previously identified using interpretative phenomenological analysis (IPA). RESULTS: Class#1 ("experience and need for better understanding"; 38.9% of semantic forms, 50% of patients) illustrates the gap that patients perceive between their experience and what others see, confirming the importance of dyspnea invisibility in patients' concerns. Class#2 ("limitations"; 28.7% of forms) and Class#3 (management"; 13.1% of forms) point to the weight of daily limitations in performing basic activities, of the need to accept or adapt to the constraints of the disease. These three classes matched previously identified IPA-derived themes. Class#4 ("hospitalization"; 18.2% of forms) points to the importance of interactions with the hospital, especially during exacerbations, which constitutes novel information. CONCLUSIONS: Lexicometry confirms the importance of dyspnea invisibility as a burden to COPD patients.

BACKGROUND: Data on assessment and management of dyspnea in patients on venoarterial extracorporeal membrane oxygenation (ECMO) for cardiogenic shock are lacking. The hypothesis was that increasing sweep gas flow through the venoarterial extracorporeal membrane oxygenator may decrease dyspnea in nonintubated venoarterial ECMO patients exhibiting clinically significant dyspnea, with a parallel reduction in respiratory drive. METHODS: Nonintubated, spontaneously breathing, supine patients on venoarterial ECMO for cardiogenic shock who presented with a dyspnea visual analog scale (VAS) score of greater than or equal to 40/100 mm were included. Sweep gas flow was increased up to +6 l/min by three steps of +2 l/min each. Dyspnea was assessed with the dyspnea-VAS and the Multidimensional Dyspnea Profile. The respiratory drive was assessed by the electromyographic activity of the alae nasi and parasternal muscles. RESULTS: A total of 21 patients were included in the study. Upon inclusion, median dyspnea-VAS was 50 (interquartile range, 45 to 60) mm, and sweep gas flow was 1.0 l/min (0.5 to 2.0). An increase in sweep gas flow significantly decreased dyspnea-VAS (50 [45 to 60] at baseline vs. 20 [10 to 30] at 6 l/min; P < 0.001). The decrease in dyspnea was greater for the sensory component of dyspnea (-50% [-43 to -75]) than for the affective and emotional components (-17% [-0 to -25] and -12% [-0 to -17]; P < 0.001). An increase in sweep gas flow significantly decreased electromyographic activity of the alae nasi and parasternal muscles (-23% [-36 to -10] and -20 [-41 to -0]; P < 0.001). There was a significant correlation between the sweep gas flow and the dyspnea-VAS (r = -0.91; 95% CI, -0.94 to -0.87), between the respiratory drive and the sensory component of dyspnea (r = 0.29; 95% CI, 0.13 to 0.44) between the respiratory drive and the affective component of dyspnea (r = 0.29; 95% CI, 0.02 to 0.54) and between the sweep gas flow and the alae nasi and parasternal (r = -0.31; 95% CI, -0.44 to -0.22; and r = -0.25; 95% CI, -0.44 to -0.16). CONCLUSIONS: In critically ill patients with venoarterial ECMO, an increase in sweep gas flow through the oxygenation membrane decreases dyspnea, possibly mediated by a decrease in respiratory drive.

PURPOSE OF REVIEW: Palliative care (PC) in lung transplantation is increasingly acknowledged for its important role in addressing symptoms, enhancing functionality, and facilitating advance care planning for patients, families, and caregivers. The present review provides an update in PC management in lung transplantation. RECENT FINDINGS: Research confirms the effectiveness of PC for patients with advanced lung disease who are undergoing transplantation, showing improvements in symptoms and reduced healthcare utilization. Assessment tools and patient-reported outcome measures for PC are commonly used in lung transplant candidates, revealing discrepancies between symptom severity and objective measures such as exercise capacity. The use of opioids to manage dyspnea and cough in the pretransplant period is deemed safe and does not heighten risks posttransplantation. However, the integration of PC support in managing symptoms and chronic allograft dysfunction in the posttransplant period has not been as well described. SUMMARY: Palliative care support should be provided in the pretransplant and select peri-operative and posttransplant periods to help support patient quality of life, symptoms, communication and daily function.

BACKGROUND AND OBJECTIVE: Persistent dyspnoea is a public health issue for which the therapeutic arsenal is limited. This study tested high-flow nasal cannula therapy (HFNT) as a means to alleviate experimental dyspnoea. METHODS: Thirty-two healthy subjects underwent an experimental dyspnoea induced by thoracoabdominal elastic loading. HFNT was administered with alternately FiO2 of 100% (HFNT100) or 21% (HFNT21). The sensory (S-VAS) and affective (A-VAS) components of dyspnoea, transcutaneous CO2 pressure (PtcCO2 ), pulse-oximetry oxygen saturation (SpO2 ), heart rate, respiratory rate and skin galvanometry were monitored continuously. Three experimental sessions of 8 min were conducted: the first session consisted in familiarization with the experimental dyspnoea and the next two sessions tested the effects of HFNT100 and HFNT21 alternatively in a randomized order. RESULTS: HFNT21 and HFNT100 significantly reduced dyspnoea, respectively of ∆A-VAS = 0.80 cm [-0.02-1.5]; p = 0.007 and ∆A-VAS = 1.00 cm [0.08-1.75]; p < 0.0001; ∆S-VAS = 0.70 cm [-0.15-1.98]), p < 0.0001 and ∆S-VAS = 0.70 cm [0.08-1.95]), p = 0.0002) with no significant difference between HFNT21 and HFNT100. HFNT did not significantly alter the respiratory rate or the heart rate, reduced PtcCO2 only on room air and GSR under both experimental conditions. CONCLUSION: HFNT was associated with a statistically significant reduction in the intensity of the sensory and affective components of dyspnoea, independent of oxygen addition. This relief of laboratory dyspnoea could result from a reduction of afferent-reafferent mismatch.

Rationale: Breathing difficulties are highly stressful. In critically ill patients, they are associated with an increased risk of posttraumatic manifestations. Dyspnea, the corresponding symptom, cannot be directly assessed in noncommunicative patients. This difficulty can be circumvented using observation scales such as the mechanical ventilation-respiratory distress observation scale (MV-RDOS). Objective: To investigate the performance and responsiveness of the MV-RDOS to infer dyspnea in noncommunicative intubated patients. Methods: Communicative and noncommunicative patients exhibiting breathing difficulties under mechanical ventilation were prospectively included and assessed using a dyspnea visual analog scale, MV-RDOS, EMG activity of alae nasi and parasternal intercostals, and EEG signatures of respiratory-related cortical activation (preinspiratory potentials). Inspiratory-muscle EMG and preinspiratory cortical activities are surrogates of dyspnea. Assessments were conducted at baseline, after adjustment of ventilator settings, and, in some cases, after morphine administration. Measurements and Main Results: Fifty patients (age, 67 [(interquartile interval [IQR]), 61-76] yr; Simplified Acute Physiology Score II, 52 [IQR, 35-62]) were included, 25 of whom were noncommunicative. Relief occurred in 25 (50%) patients after ventilator adjustments and in 21 additional patients after morphine administration. In noncommunicative patients, MV-RDOS score decreased from 5.5 (IQR, 4.2-6.6) at baseline to 4.2 (IQR, 2.1-4.7; P < 0.001) after ventilator adjustments and 2.5 (IQR, 2.1-4.2; P = 0.024) after morphine administration. MV-RDOS and alae nasi/parasternal EMG activities were positively correlated (ρ = 0.41 and 0.37, respectively). MV-RDOS scores were higher in patients with EEG preinspiratory potentials (4.9 [IQR, 4.2-6.3] vs. 4.0 [IQR, 2.1-4.9]; P = 0.002). Conclusions: The MV-RDOS seems able to detect and monitor respiratory symptoms reasonably well in noncommunicative intubated patients.

BACKGROUND: Older adults have complex medical needs that causes increased use of resources at the emergency department (ED). The prevalence of non-specific complaint (NSC) as a chief-complaint in the ED is common among older adults and is not prioritized even though possibly having worse clinical outcome. The objective was to study hospital admission and mortality for older adults visiting the ED with NSC compared to specific complaints such as dyspnea, chest pain and abdominal pain. METHODS: A retrospective observational study of older adults visiting the ED with NSC and specific complaints; dyspnea, chest pain and abdominal pain was performed. Chief-complaint were collected from electronic medical records. Fatigue, confusion, non-specific complaints, generalized weakness and risk of falling were defined as non-specific complaint (NSC) when registered as chief-complaint at the ED. Admission rate and 30-days mortality were the primary outcomes. RESULTS: A total of 4927 patients were included in the study based on chief-complaint; patients with chest pain 1599 (32%), dyspnea 1343 (27%), abdominal pain 1460 (30%) and NSC 525 (11%). Patients with dyspnea and NSC had the highest hospital admission rate 79% vs 70% compared to patients with chest pain (63%) and abdominal pain (61%) (p = < 0.001). Patients with NSC had a mean LOS 4.7 h at the ED which was significantly higher compared to chest pain, dyspnea and abdominal pain. Mean bed-days for the whole population was 4.2 days compared to patients with NSC who had a mean LOS of 5.6 days. NSC and dyspnea were both associated with the highest 30-day mortality. CONCLUSION: Older patients who present with NSC at the ED are associated with a high risk for admission and 30-days mortality. In addition, patients with NSC have a longer LOS at the ED, a high admission rate and the highest number of bed-days once admitted. This study indicates that ED staff should be more vigilant when an elderly patient presents with NSC at the ED. Further studies and guidelines are needed to improve the management of these individuals.

BACKGROUND: Breathlessness is a prevalent symptom affecting the quality of life (QOL) of Amyotrophic Lateral Sclerosis (ALS) patients. This systematic review explored the interventions for controlling breathlessness in ALS patients, emphasizing palliative care (PALC), non-invasive ventilation (NIV), opioids, and non-pharmacological strategies. METHODS: A comprehensive search of PubMed, Cochrane Library, and Web of Science databases was conducted. Eligibility criteria encompassed adults with ALS or motor neuron disease experiencing breathlessness. Outcomes included QOL and symptom control. Study designs comprised qualitative studies, cohort studies, and randomized controlled trials. RESULTS: Eight studies were included, most exhibiting low bias risk, comprising one randomized controlled trial, three cohort studies, two comparative retrospective studies, and two qualitative studies (interviews). Most studies originated from Europe, with one from the United States of America. The participants totaled 3423, with ALS patients constituting 95.6%. PALC consultations significantly improved symptom assessment, advance care planning, and discussions about goals of care. NIV demonstrated efficacy in managing breathlessness, with considerations for device limitations. Opioids were effective, though predominantly studied in non-ALS patients. Non-pharmacological strategies varied in efficacy among patients. CONCLUSION: The findings underscore the need for individualized approaches in managing breathlessness in ALS. PALC, NIV, opioids, and non-pharmacological strategies each play a role, with unique considerations. Further research, especially ALS-specific self-management studies, is warranted.

Context: In addition to pharmacological approaches, clinicians use nonpharmacological approaches in the management of dyspnea, one of which is fan therapy. It's a simple, cost-effective intervention that patients can easily use independently, without requiring professional support. The field needs further research on the outcomes of fan use. Objective: The study intended to determine the effectiveness of fan therapy in relieving dyspnea for patients with dyspnea symptoms. Design: The research team conducted a single-group, pretest-posttest study. Setting: The study occurred at the Prof. Dr. Murat Dilmener Emergency Hospital, which is an additional service building of the Bakirkoy Dr. Sadi Konuk Training and Research Hospital in Istanbul, Turkey. Participants: Participants were 81 patients with respiratory distress who received inpatient treatment at the hospital between March 2022 and June 2023. Intervention: The research team used a hand fan for 5 minutes to cool participants' faces. Outcome Measures: At 15 minutes post fan therapy, the research team: (1) measured patients' dyspnea levels using with Modified Borg Scale (MBS), (2) oxygen saturation, (3) respiratory rate, (4) pulse rate, (5) body temperature, (6) blood pressure, and (7) respiratory-muscle-use status. Results: Between baseline and post intervention, participants' oxygen saturation (P = .001) significantly increased and respiration rates (P = .014), systolic blood pressure (P = .003), diastolic blood pressure (P = .001), use of accessory respiratory muscles (P = .003), and MBS values (P = .001) significantly decreased. At baseline, a high dyspnea level was significantly negatively correlated with an age >67 (P = .019), BMI >25.0 (P = .044), an oxygen saturation of <95 (P = .005), and respiratory rate >20/pm (P = .001) and significantly positively correlated with a severe need for oxygen support (P = .035), a pulse rate >100/pm (P = .001), and hypertension (P = .005). Post intervention, a high dyspnea level was significantly positively correlated with smoking (P = .008), a need for oxygen support (P = .001), a severe need of oxygen support (P = .017), and hypertension (P = .001) and significantly negatively correlated with oxygen saturation <95 (P = .002). Conclusions: Fan therapy directed to the face can be effective in reducing the dyspnea level. With the therapy being a simple, reliable, and cost-effective method that nurses, patients, and their families can use, the current research team concludes that clinicians can use it together with pharmacological methods for patients experiencing dyspnea.

OBJECTIVE: This study examined the number of therapy sessions required to sufficiently improve (exercise) induced laryngeal obstruction (EILO/ILO) symptoms for discharge. Factors predicting therapy duration were examined as was the likelihood of patients returning for additional therapy sessions following initial discharge. METHODS: Retrospective observational cohort design. Data for 350 patients were gathered from the University of Wisconsin-Madison Voice and Swallow Clinics Outcome Database. Patients (>18 years of age) diagnosed with EILO/ILO received therapy from a Speech-Language Pathologist (SLP) and were successfully discharged. EILO/ILO treatment details, symptoms, triggers, medical comorbidities, and patient demographics were collected from initial evaluations and subsequent course of therapy. RESULTS: Patients required an average of 3.59 (SD = 3.7) therapy sessions prior to discharge. A comorbid behavioral health diagnosis (p = .026), higher Vocal Handicap Index Score (p = .009) and reduced physical activity due to EILO/ILO symptoms (p = .032) were associated with increased therapy duration. Patients with ILO or EILO with secondary environmental triggers required significantly more sessions than those with exercise-induced symptoms (p < .01). Eight percent of patients returned for additional sessions following discharge. Patients returning for additional sessions all came from affluent neighborhoods as measured by the Area Deprivation Index (ADI). CONCLUSIONS: Patients with EILO/ILO required an average of 3.59 therapy sessions prior to discharge. As such, 4 sessions is a reasonable estimate for clinicians to provide patients. Six sessions may be a more conservative estimate for patients who present with a behavioral health diagnosis, a voice complaint, or reduced physical activity from EILO/ILO symptoms.

PURPOSE: An accurate diagnosis and proper treatment plan are required to restore an adequate patent airway in fibrotic subglottic stenosis (SGS). Currently, the definitive treatment entails single-stage balloon dilatation with steroid injections. The primary aim was to evaluate successful airway restoration and general quality of life in cases with SGS in northern Sweden using robust patient reported outcomes. METHODS: All participants with need of surgical treatment due to SGS that had been referred to the department of otorhinolaryngology, University Hospital of Umeå from September 2020 to August 2023 was included. Exclusion criteria included malignant, extrathoracic or cartilaginous cause, age < 18 years, or incompetent to sign consent documents. We assessed the patient-reported outcome measures pre- as well as 3 months postoperatively. RESULTS: Of the 40 cases fulfilling the eligibility criteria's, 33 cases completed the Dyspnea index (DI) and the short form health survey (SF-36) pre- as well as 3 months post-operatively. Receiver operating characteristics showed significant improvement in DI as well as in SF 36 scores post-operatively. CONCLUSIONS: Evaluation of balloon dilatation in SGS in this cohort follow-up analysis shows clear improvement in patient quality of life using robust PROM 3 months postoperatively, ensuring the use of a safe and well-tolerated procedure.

INTRODUCTION: Chronic refractory breathlessness is a debilitating symptom which negatively affects quality of life with profound impact on physical and psychosocial functioning of patients and/or carers. Multidisciplinary based interventions which focus on non-pharmacological approach have shown to be effective. We developed a breathlessness intervention service called breathlessness supportive therapy (BST) in a palliative care unit with limited resources. The aim is to evaluate the feasibility of developing a BST service and to study the characteristics and outcome of patients with chronic refractory breathlessness. MATERIALS AND METHODS: This is a retrospective study of patients with chronic refractory breathlessness and Modified Medical Research Council (mMRC) dyspnoea scale grade ≥ 2 who attended the BST clinic over 1 year period. BST consists of two clinic sessions 2 weeks apart. Data was retrieved from patients' medical notes and analysis done using Microsoft Excel. RESULTS: A total of 21 patients were identified. Median age was 69 years with 52% of females. 72% had non-malignant diagnoses. Median Charlson's Comorbidity Index score was 6.5. Median mMRC dyspnoea scale was 3. 47.6% had long term oxygen usage. Median Australian Karnofsky Performance Scale (AKPS) was 65 and the median baseline breathlessness visual analogue scale (VAS) was 2. 62% completed two sessions, the remaining 38% completed only one session. Mean time from BST intervention to death was 18.26 weeks, median was 22 weeks. 72% died at home, whilst 28% died in the hospital. All the patients scored 4 (somewhat agree) and 5 (strongly agree) on the overall feedback score. CONCLUSIONS: Development of a breathlessness intervention service is feasible in a resource limited setting and generally accepted by most patients. More research and prospective studies are needed to evaluate the effectiveness of BST in the future.

INTRODUCTION: Dyspnea is a common and distressing symptom in patients with advanced malignant and non-malignant diseases. It is a subjective experience that can only be described by the patients themselves and can be associated with a massive reduction in quality of life, including social isolation and wish to hasten death. Often there is an affective component such as anxiety or panic. Objective parameters do not necessarily correlate with the subjective experience. Health professionals often underestimate and inadequately treat the burden of dyspnea. The introduction of the concept of chronic breathlessness syndrome or acute-on-chronic-breathlessness aims to illustrate the nature of the condition and facilitate the identification and access to appropriate treatment. The management of dyspnea is complex, and for effective treatment, a combination of general, non-pharmacological, and pharmacological measures is usually advisable. Opioids should be offered to patients with incurable cancer and refractory dyspnea for symptom relief. They can be supplemented with benzodiazepines in cases of concomitant anxiety. The administration of oxygen is only indicated in cases of hypoxemia. Key measures include education, self-management skills acquisition and advance care planning for emergency situations.

Exercise-induced laryngeal obstruction (EILO) is a condition characterized by temporary narrowing or closure of the larynx during physical activity, in particular during intense physical exertion. It generally affects teenagers and young adults and is often misdiagnosed as exercise-induced asthma. Symptoms include dyspnea, wheezing and a feeling of throat tightness during exercise. The aim of this article is to review this often underrecognized condition, its diagnosis and its management.
L'obstruction laryngée induite à l'effort (EILO) est une affection caractérisée par le rétrécissement ou la fermeture temporaire du larynx au cours d'une activité physique, en particulier lors d'un effort physique intense. Elle touche généralement les adolescents et les jeunes adultes et est souvent diagnostiquée à tort comme de l'asthme d'effort. Les symptômes comprennent une dyspnée, une respiration sifflante et une sensation d'oppression au niveau de la gorge pendant l'exercice. Cet article passe en revue cette pathologie souvent méconnue, son diagnostic et sa prise en charge.

Long COVID is a common occurrence after an infection with COVID-19. Most frequent symptoms are fatigue, shortness of breath, and cognitive dysfunction. Options for treatment are limited, mainly symptomatic. There is a solid theoretical background for the successful treatment with Hyperbaric Oxygen Therapy (HBOT) of the pathophysiological changes caused by the COVID-19 infection and their reversal. Case presentation: The data presented was collected from the test results of total of 63 male and female patients, treated from 15th January 2021 to 19th April 2022, aged 22 to 74 years old, all of them presenting with symptoms of Long COVID. A standard 2.4 ATA HBOT treatment table for approved elective HBOT indications was used for the treatment of Long COVID patients, with a course duration of 10 or 15 sessions. The key concept is that HBOT works on a cellular level, specifically affecting the oxidative phosphorylation and energy metabolism in the mitochondria. Results: Hyperbaric Oxygen Therapy delivered positive results in all observed Long COVID related symptoms, particularly those associated with the nervous system, cognitive function, psychological well-being, and physical fatigue. Approximately 90% of all patients improved compared to their initial state, in most cases significantly. No adverse effects were reported. Feedback received three months after treatment demonstrated that the benefits were persistent.

BACKGROUND: Indwelling pleural catheters are an effective treatment option for patients with malignant pleural effusions. Despite their popularity, there remains a paucity of data on the patient experience and key patient-centred outcomes. OBJECTIVE: To investigate the experience of patients receiving an indwelling pleural catheter to better inform and identify potential areas for improvement in care. METHODS: This was a multicentre survey study at three academic, tertiary-care centres in Canada. Patients with a diagnosis of malignant pleural effusion who had an indwelling pleural catheter inserted were included. An adapted questionnaire specific to indwelling pleural catheters was used with responses recorded on a 4-point Likert scale. Patients completed the questionnaire in-person or by phone at 2-week and 3-month follow-up appointments. RESULTS: A total of 105 patients were enrolled in the study with 84 patients included in the final analysis. At the 2-week follow-up, patient-reported improvements in dyspnoea and quality of life from indwelling pleural catheter were high at 93% and 87%, respectively. The predominant issues identified were discomfort at time of insertion (58%), itching (49%), difficulty with sleeping (39%), discomfort with home drainage (36%) and the pleural catheter reminding patients of their disease (63%). Avoiding hospitalisation for the management of dyspnoea was important to 95% of patients. Findings were similar at 3 months. CONCLUSIONS: Indwelling pleural catheters are an effective intervention to directly improve dyspnoea and quality of life but have important disadvantages for some; clinicians and patients should be aware of these when making an informed decision regarding treatment.

BACKGROUND: In advanced disease, breathlessness becomes severe, increasing health services use. Breathlessness triggered services demonstrate effectiveness in trials and meta-analyses but lack health economic assessment. METHODS: Our economic study included a discrete choice experiment (DCE), followed by a cost-effectiveness analysis modelling. The DCE comprised face-to-face interviews with older patients with chronic breathlessness and their carers across nine UK centres. Conditional logistic regression analysis of DCE data determined the preferences (or not, indicated by negative ß coefficients) for service attributes. Economic modelling estimated the costs and quality-adjusted life years (QALYs) over 5 years. FINDINGS: The DCE recruited 190 patients and 68 carers. Offering breathlessness services in person from general practitioner (GP) surgeries was not preferred (ß=-0.30, 95% CI -0.40 to -0.21); hospital outpatient clinics (0.16, 0.06 to 0.25) or via home visits (0.15, 0.06 to 0.24) were preferred. Inperson services with comprehensive treatment review (0.15, 0.07 to 0.21) and holistic support (0.19, 0.07 to 0.31) were preferred to those without. Cost-effectiveness analysis found the most and the least preferred models of breathlessness services were cost-effective compared with usual care. The most preferred service had £5719 lower costs (95% CI -6043 to 5395), with 0.004 (95% CI -0.003 to 0.011) QALY benefits per patient. Uptake was higher when attributes were tailored to individual preferences (86% vs 40%). CONCLUSION: Breathlessness services are cost-effective compared with usual care for health and social care, giving cost savings and better quality of life. Uptake of breathlessness services is higher when service attributes are individually tailored.
