Review of the Evidence for Pulmonary Rehabilitation in COPD: Clinical Benefits and Cost-Effectiveness.

COPD is a common and lethal chronic condition, recognized as a leading cause of death worldwide. COPD is associated with significant morbidity and disability, particularly among older adults. The disease course is marked by periods of stability and disease exacerbations defined by worsening respiratory status resulting in a high burden of health care utilization and an increased risk of mortality. Treatment is focused on pharmacologic therapies, but these are not completely effective. Pulmonary rehabilitation (PR) represents a key medical intervention for patients with chronic respiratory diseases, including COPD. PR provides individualized and progressive exercise training, education, and self-management strategies through a comprehensive and multidisciplinary program. PR has been associated with improvement in exercise capacity, health-related quality of life, and dyspnea in patients living with COPD. Moreover, PR has been associated with improvements in hospital readmission and 1-y survival. In addition to the clinical benefits, PR is estimated to be a cost-effective medical intervention. Despite these benefits, participation in PR remains low. We will review the evidence for PR in each of these benefit domains among patients with stable COPD and in those recovering from a COPD exacerbation.

Low-intensity rehabilitation in persistent post COVID-19 dyspnoea: the value of Spa health resort as appropriate setting.

Background: Post COVID-19 syndrome is a frequent disabling outcome, leading to a delay in social reintegration and return to working life. Study design: This was a prospective observational cohort study. The main objective was to explore the effectiveness of a Spa rehabilitation treatment on the improvement of post COVID-19 dyspnoea and fatigue, also analyzing the relationship between such symptoms. Additionally, it was assessed if different clinical characteristics could predispose patients in experiencing post COVID-19 symptoms or could influence the effectiveness of a Spa intervention. Methods: From July to November 2021, 187 post COVID-19 patients were enrolled in the study. All the patients complained persi-sting dyspnoea, whose impact on daily activities was assessed using the modified Medical Research Council dyspnoea scale. 144 patients (77.0%) reported also fatigue. The Spa treatment was started at least 3 months after COVID-19 acute phase. At the end of the treatment, patients were asked to rate the improvement in the dyspnoea and fatigue sensation. 118 patients also underwent the modified Borg Dyspnoea Scale for severity estimation of Exertion Dyspnoea and the Barthel index for severity estimation of Physical Limitation. Results: 165 out of 187 patients (88.2%) reported an improvement in dyspnoea, while 116 out 144 patients (80.6%) reported an improvement in both dyspnoea and fatigue. On a total of 118 subjects, a clinically significant improvement in the modified Borg Dyspnoea Scale (i.e. Delta Borg equal or more than -2.0 points) was reached by the 50.8% of patients, while a clinically significant improvement in the Barthel index (i.e. Delta Barthel equal or more than +10.0 points) was reached by the 51.7% of them. The 31.4% of patients reached a minimal clinically important improvement in both the modified Borg Dyspnoea Scale and the Barthel index. No risk factors were associated to a clinically impacting dyspnoea at entry, while a BMI>30 Kg/m2 was the main risk factor for chronic fatigue. Presence of respiratory comorbidities, obesity and severe acute COVID-19 (phenotype 4) configured risk factors for the lack of improvement of dyspnoea after the treatment, while no risk factors were associated to a lack of improvement for fatigue. Older age, obesity and comorbidities seemed to make more difficult to reach a clinically meaningful improvement in the modified Borg Dyspnoea Scale and the Barthel index after treatment. Female gender may imply more physical limitation at entry, while male patients seem to show less improvement in the Barthel index after treatment. Conclusions: Dyspnoea and fatigue were confirmed to be important post COVID-19 symptoms even in younger subjects of wor-king age and subjects with absent or modest pulmonary alterations at distance from acute COVID-19. A Spa health resort seems to be an effective "low-intensity" setting for a rehabilitation program of such patients. There is a strong relationship in terms of improvement between dyspnoea and fatigue, even if risk factors for their occurrence appear to be different. The improvement in exertion dyspnoea and physical limitation seemed to be less mutually related, probably due to a greater complexity in the asses-sment questionnaires. Some risk factors may predict a lack of improvement in symptoms after treatment.

Integrative Assessment of Cardiopulmonary Fitness Using Cardiopulmonary Exercise Test With Supine Bicycle Echocardiography in Patients Presenting Dyspnea.

BACKGROUND: Cardiopulmonary exercise test (CPET) with supine bicycle echocardiography (SBE) enables comprehensive physiologic assessment during exercise. We characterized cardiopulmonary fitness by integrating CPET-SBE parameters and evaluated its prognostic value in patients presenting with dyspnea. METHODS AND RESULTS: We retrospectively reviewed 473 consecutive patients who underwent CPET-SBE for dyspnea evaluation. A dimensionality reduction process was applied, transforming 24 clinical and CPET-SBE parameters into a 2-dimensional feature map, followed by patient clustering based on the data distribution. Clinical and exercise features were compared among the clusters in addition to the 5-year risk of clinical outcome (a composite of cardiovascular death and heart failure hospitalization). Maximum exercise effort (R >1) was achieved in 95% of cases. Through dimensionality reduction, 3 patient clusters were derived: Group 1 (n=157), 2 (n=104), and 3 (n=212). Median age and female proportion increased from Group 1 to 2, and 3, although resting echocardiography parameters showed no significant abnormalities among the groups. There was a worsening trend in the exercise response from Group 1 to 2 and 3, including left ventricular diastolic function, oxygen consumption, and ventilatory efficiency. During follow-up (median 6.0 [1.6-10.4] years), clinical outcome increased from Group 1 to 2 and 3 (5-year rate 3.7% versus 7.0% versus 13.0%, respectively; log-rank P=0.02), with higher risk in Group 2 (hazard ratio, 1.94 [95% CI, 0.52-7.22]) and Group 3 (3.92 [1.34-11.42]) compared with Group 1. CONCLUSIONS: Comprehensive evaluation using CPET-SBE can reveal distinct characteristics of cardiopulmonary fitness in patients presenting with dyspnea, potentially enhancing outcome prediction.

[COPD: diagnostic and severity assessment]. / Diagnostic et évaluation de la gravité de la BPCO.

COPD: DIAGNOSTIC AND SEVERITY ASSESSMENT. Chronic obstructive pulmonary disease (COPD) is a frequent and underdiagnosed respiratory disease and a leading cause of morbidity and mortality. It should be suspected in patients aged 40 and over presenting with persistent respiratory symptoms (cough, sputum, shortness of breath, recurrent respiratory tract infections) and a history of exposure to risk factors for the disease (smoking, occupational or domestic exposure to noxious particles). Spirometry is required to confirm the diagnosis of COPD, showing persistent airflow limitation with a post-bronchodilator FEV1/FCV inférieur 0.7. COPD assessment includes: classification of airflow limitation severity with post-bronchodilator FEV1 measurement (GOLD score from 1 to 4), clinical severity assessment (intensity of dyspnea, number and severity of acute exacerbations, impaired quality of life) and evaluation of associated complications (chronic respiratory failure, hypercapnia, pulmonary hypertension). Comorbidities are frequent and should be carefully sought: lung cancer, cardiovascular diseases, metabolic syndrome, skeletal muscle dysfunction, sleep apnea syndrome, osteoporosis, anxiety and depression.

Hidden in plain sight - Survival consequences of baseline symptom burden in women with recurrent ovarian cancer.

OBJECTIVE: To describe the baseline symptom burden(SB) experienced by patients(pts) with recurrent ovarian cancer(ROC) prior and associations with progression free survival (PFS) and overall survival (OS). METHODS: We analysed baseline SB reported by pts. with platinum resistant/refractory ROC (PRR-ROC) or potentially­platinum sensitive ROC receiving their third or greater line of chemotherapy (PPS-ROC≥3) enrolled in the Gynecologic Cancer InterGroup - Symptom Benefit Study (GCIG-SBS) using the Measure of Ovarian Symptoms and Treatment concerns (MOST). The severity of baseline symptoms was correlated with PFS and OS. RESULTS: The 948 pts. reported substantial baseline SB. Almost 80% reported mild to severe pain, and 75% abdominal symptoms. Shortness of breath was reported by 60% and 90% reported fatigue. About 50% reported moderate to severe anxiety, and 35% moderate to severe depression. Most (89%) reported 1 or more symptoms as moderate or severe, 59% scored 6 or more symptoms moderate or severe, and 46% scored 9 or more symptoms as moderate or severe. Higher SB was associated with significantly shortened PFS and OS; five symptoms had OS hazard ratios larger than 2 for both moderate and severe symptom cut-offs (trouble eating, vomiting, indigestion, loss of appetite, and nausea; p < 0.001). CONCLUSION: Pts with ROC reported high SB prior to starting palliative chemotherapy, similar among PRR-ROC and PPS-ROC≥3. High SB was strongly associated with early progression and death. SB should be actively managed and used to stratify patients in clinical trials. Clinical trials should measure and report symptom burden and the impact of treatment on symptom control.

Post-COVID-19 syndrome: persistent symptoms, functional impact, quality of life, return to work, and indirect costs - a prospective case study 12 months after COVID-19 infection. / Síndrome pós-COVID-19: sintomas persistentes, impacto funcional, qualidade de vida, retorno laboral e custos indiretos - estudo prospectivo de casos 12 meses após a infecção.

The persistent symptoms of post-COVID-19 syndrome negatively impact health, quality of life, and productivity. This study aimed to describe the persistent symptoms of post-COVID-19 syndrome (especially neurological ones) and their 12-month post-infection cognitive, emotional, motor, quality of life, and indirect cost repercussions. Patients showing the first symptoms of COVID-19 from January to June 2021 who developed post-COVID-19 syndrome and sought care at the Fortaleza Unit (Ceará, Brazil) of the SARAH Network of Rehabilitation Hospitals were included in this study. Information was obtained at the baseline follow-up and by telephone interview 12 months post-infection. In total, 58 people participated in this study with an average age of 52.8±10.5 years, of which 60% required an ICU. The most frequent symptoms on admission included fatigue (64%), arthralgia (51%), and dyspnea (47%), whereas, after 12 months, fatigue (46%) and memory impairment (39%). The following scales/functional tests showed alterations: PCFS, MoCA, HAD, FSS, SF-36, TLS5x, timed up and go, 6-minute walk, and handgrip. Indirect costs totaled USD 227,821.00, with 11,653 days of absenteeism. Moreover, 32% of patients were unable to return to work. Better TLS5x and higher SF-36 scores in the functional capacity, physical functioning, vitality, and pain dimensions were associated with return to work (p ≤ 0.05). The most frequent persistent symptoms referred to fatigue, arthralgia, dyspnea, anxiety, and depression, which negatively affected cognitive, emotional, and motor function and quality of life. These symptoms lasted for over a year, especially fatigue and memory alteration, the latter of which being the most reported after COVID-19 infections. Results also show a significant difficulty returning to work and indirect costs of USD 4,847.25 per person/year.

Characteristics and burden of acute COVID-19 and long-COVID: Demographic, physical, mental health, and economic perspectives.

BACKGROUND: COVID-19 infection and its associated consequence, known as long-COVID, lead to a significant burden on the global healthcare system and limitations in people's personal and work lives. This study aims to provide further insight into the impact of acute and ongoing COVID-19 symptoms and investigates the role of patients' gender and vaccination status. METHODS: 416 individuals (73.9% female) between the ages of 16 and 80 years (M = 44.18, SD = 12.90) with self-reported symptoms of long-COVID participated in an online survey conducted between March and May 2022. RESULTS: 6.0%, 74.3%, and 19.7% of all respondents reported having had an asymptomatic, mild, or severe acute illness, respectively. Out of all participants, 7.8% required hospitalization. The most prevalent symptoms during the acute infection (Mdn = 23.50 symptoms, IQR = 13-39) included fatigue, exhaustion, cough, brain fog, and memory problems. The median long-COVID disease duration was 12.10 months (IQR = 2.8-17.4). Among 64 inquired long-COVID symptoms (Mdn = 17.00 symptoms, IQR = 9-27), participants reported fatigue, exhaustion, memory problems, brain fog, and dyspnea as the most common ongoing symptoms, which were generally experienced as fluctuating and deteriorating after physical or cognitive activity. Common consequences of long-COVID included financial losses (40.5%), changes in the participants' profession (41.0%), stress resistance (87.5%), sexual life (38.1%), and mood (72.1%), as well as breathing difficulties (41.3%), or an increased drug intake (e.g., medicine, alcohol; 44.6%). In addition, vaccinated individuals exhibited a shorter acute illness duration and an earlier onset of long-COVID symptoms. In general, women reported more long-COVID symptoms than men. CONCLUSION: Long-COVID represents a heterogeneous disease and impacts multiple life aspects of those affected. Tailored rehabilitation programs targeting the plurality of physical and mental symptoms are needed.

Assessment of acute asthma in children: do parents and healthcare providers speak the same language?

OBJECTIVE: Education and self-management plans enhance parents' self-efficacy in managing their child's asthma symptoms. By understanding how parents recognize and interpret acute asthma symptoms, we can compile patient information using terms that are familiar to parents. METHOD: Semi-structured interviews were carried out with 27 parents of children with asthma aged 2-12 years. The interviewees were selected from three groups: parents of children admitted for acute asthma, parents of children receiving outpatient asthma care, and parents who had access to a self-management plan. Parents were invited to report symptoms they would associate with acute asthma. Subsequently, parents were queried about their recognition of symptoms from a predefined list and asked to explain how they would assess these symptoms in case their child would experience an attack of acute asthma. RESULTS: The most frequently reported symptoms for acute asthma were shortness of breath (77.8%) and coughing (63%). Other signs such as retractions, nasal flaring, and wheezing were reported by less than 25% of the parents. All parents recognized shortness of breath, wheezing and gasping for breath from a predefined list of medical terms. Retractions and nasal flaring were recognized by 81.5% and 66.7% of the parents, respectively. Recognizing the medical terms did not necessarily translate into parents being able to explain how to assess these symptoms. CONCLUSION: Parents and healthcare professionals do not always speak the same language concerning symptoms of acute asthma. This may hamper timely recognition and adequate self-management, highlighting the necessity to adjust current medical information about acute asthma.

Education and self-management plans enhance parents' self-efficacy in managing their child's asthma symptoms.Parents may identify symptoms of acute asthma differently than healthcare providersInformation material about acute asthma should be adjusted to empower parents to decide when to commence treatment and when to seek medical attention.

Assessment of the cardiac output at rest and during exercise stress using real-time cardiovascular magnetic resonance imaging in HFpEF-patients.

This methodological study aimed to validate the cardiac output (CO) measured by exercise-stress real-time phase-contrast cardiovascular magnetic resonance imaging (CMR) in patients with heart failure and preserved ejection fraction (HFpEF). 68 patients with dyspnea on exertion (NYHA ≥ II) and echocardiographic signs of diastolic dysfunction underwent rest and exercise stress right heart catheterization (RHC) and CMR within 24 h. Patients were diagnosed as overt HFpEF (pulmonary capillary wedge pressure (PCWP) ≥ 15mmHg at rest), masked HFpEF (PCWP ≥ 25mmHg during exercise stress but < 15mmHg at rest) and non-cardiac dyspnea. CO was calculated using RHC as the reference standard, and in CMR by the volumetric stroke volume, conventional phase-contrast and rest and stress real-time phase-contrast imaging. At rest, the CMR based CO showed good agreement with RHC with an ICC of 0.772 for conventional phase-contrast, and 0.872 for real-time phase-contrast measurements. During exercise stress, the agreement of real-time CMR and RHC was good with an ICC of 0.805. Real-time measurements underestimated the CO at rest (Bias:0.71 L/min) and during exercise stress (Bias:1.4 L/min). Patients with overt HFpEF had a significantly lower cardiac index compared to patients with masked HFpEF and with non-cardiac dyspnea during exercise stress, but not at rest. Real-time phase-contrast CO can be assessed with good agreement with the invasive reference standard at rest and during exercise stress. While moderate underestimation of the CO needs to be considered with non-invasive testing, the CO using real-time CMR provides useful clinical information and could help to avoid unnecessary invasive procedures in HFpEF patients.

An assessment of the immune status of some stone quarry workers in Ondo state, Nigeria.

Stone quarry activities in Nigeria are mostly unregulated such that the workers in these quarries are continuously exposed to the inhalation of silica dust. It has been observed that silica dust particles negatively impact the health of stone quarry workers which usually manifest as respiratory difficulties, asthma-like illnesses and other adventitious events of the lungs. The study was designed to evaluate the probable immunological impact of silica dust inhalation from stone crushing by workers. Blood samples were collected from consenting workers and analyzed for total white blood cells and their subsets. Absolute CD4 cells numbers were also determined. The results indicated that neutrophils and eosinophils numbers increased significantly (P < .05) and CD4 counts declined significantly (P < .001). Alteration in these proportions is a pointer to the injurious impact of silica dust on the immune system of these workers. The findings in this study should spur actions in the education of these workers on the need for the use of proper personal protection equipment and the establishment of a scheme to periodically carry out a health assessment check to identity those at most risk of developing chronic illnesses.

Impact of socioeconomic status on presentation, care quality and outcomes of patients attended by emergency medical services for dyspnoea: a population-based cohort study.

BACKGROUND: Low socioeconomic status (SES) has been linked to poor outcomes in many conditions. It is unknown whether these disparities extend to individuals presenting with dyspnoea. We aimed to evaluate the relationship between SES and incidence, care quality and outcomes among patients attended by emergency medical services (EMS) for dyspnoea. METHODS: This population-based cohort study included consecutive patients attended by EMS for dyspnoea between 1 January 2015 and 30 June 2019 in Victoria, Australia. Data were obtained from individually linked ambulance, hospital and mortality datasets. Patients were stratified into SES quintiles using a composite census-derived index. RESULTS: A total of 262 412 patients were included. There was a stepwise increase in the age-adjusted incidence of EMS attendance for dyspnoea with increasing socioeconomic disadvantage (lowest SES quintile 2269 versus highest quintile 889 per 100 000 person years, ptrend<0.001). Patients of lower SES were younger and more comorbid, more likely to be from regional Victoria or of Aboriginal or Torres Strait Islander heritage and had higher rates of respiratory distress. Despite this, lower SES groups were less frequently assigned a high acuity EMS transport or emergency department (ED) triage category and less frequently transported to tertiary centres or hospitals with intensive care unit facilities. In multivariable models, lower SES was independently associated with lower acuity EMS and ED triage, ED length of stay>4 hours and increased 30-day EMS reattendance and mortality. CONCLUSION: Lower SES was associated with a higher incidence of EMS attendances for dyspnoea and disparities in several metrics of care and clinical outcomes.

Timely Assessment of Breathing-Related Distress in Community Palliative Care: A Multidisciplinary Collaborative Quality Improvement Project.

Background: Breathlessness is a common symptom for palliative patients that can cause distress and decrease function and quality of life. Palliative care services in Australia aim to routinely assess patients for breathing-related distress, but timely reassessment is not always achieved. Objective: To improve the timeliness of breathlessness reassessment in a home-based community palliative care service in New South Wales for people with moderate-to-severe breathing-related distress. Breathing-related distress was defined as a Symptom Assessment Score for "breathing problems" of four or more. Methods: This collaborative quality improvement (QI) project between SPHERE Palliative Care CAG, Stanford University mentors, and a Sydney metropolitan specialist palliative care service included a: (1) retrospective chart audit; (2) cause and effect analyses using a fishbone diagram; (3) development and implementation of key drivers and interventions; and (4) a pre-and-post evaluation of the timeliness of reassessment of breathing-related distress and changes in Symptom Assessment Scale scores for "breathing problems." Results: Key interventions included multidisciplinary education sessions to facilitate buy-in, with nurses as case managers responsible for breathlessness reassessment and documentation of scores, access and training in electronic palliative care data entry software, fortnightly monitoring and reporting of breathing-related distress scores, and development of an educational flowchart. The proportion of patients reassessed within seven days of an initial nursing assessment of moderate-to-severe breathing-related distress increased from 34% at baseline to 92% at six months. Conclusion: A local QI project increased the proportion of patients with a timely reassessment of their breathing-related distress in a community palliative care service.

Associations Between Certificate of Need Policies and Hospice Quality Outcomes.

BACKGROUND: Certificate of need (CON) laws are state-based regulations requiring approval of new healthcare entities and capital expenditures. Varying by state, these regulations impact hospices in 14 states and DC, with several states re-examining provisions. AIM: This cross-sectional study examined the association of CON status on hospice quality outcomes using the hospice item set metric (HIS). DESIGN: Data from the February 2022 Medicare Hospice Provider and General Information reports of 4870 US hospices were used to compare group means of the 8 HIS measures across CON status. Multiple regression analysis was used to predict HIS outcomes by CON status while controlling for ownership and size. RESULTS: Approximately 86% of hospices are in states without a hospice CON provision. The unadjusted mean HIS scores for all measures were higher in CON states (M range 94.40-99.59) than Non-CON (M range 90.50-99.53) with significant differences in all except treatment preferences. In the adjusted model, linear regression analyses showed hospice CON states had significantly higher HIS ratings than those from Non-CON states for beliefs and values addressed (ß = .05, P = .009), pain assessment (ß = .05, P = .009), dyspnea treatment (ß = .08, P < .001) and the composite measure (ß = .09, P < .001). Treatment preferences, pain screening, dyspnea screening, and opioid bowel treatment were not statistically significant (P > .05). CONCLUSION: The study suggests that CON regulations may have a modest, but beneficial impact on hospice-reported quality outcomes, particularly for small and medium-sized hospices. Further research is needed to explore other factors that contribute to HIS outcomes.

Assessment of mask use on oxygen saturation in adults and children with asthma.

Background: Mask use is recommended to reduce the transmission of severe acute respiratory syndrome coronavirus 2. The safety of mask use in adults and children with asthma is unknown. Objective: The objective of this study is to evaluate the effect of mask use on peripheral oxygen saturation (SpO2) in those with and those without asthma. Methods: A two-stage cross-sectional study was performed. In the first stage, the SpO2 concentration in adults and children with and without asthma was measured with the adults and children at rest during mask use. In the second stage, children years 6-17 performed a 6-minute walk test while wearing masks. The SpO2 concentration was measured before the exercise and at 3 and 6 minutes into exercise. Subjective dyspnea was evaluated by using the Pediatric Dyspnea Scale (PDS). Results: In the first stage, SpO2 levels in 393 subjects were analyzed. In the second stage, 50 pediatric subjects were included, 25 with and 25 without asthma. There was no difference in SpO2 levels between those with and those without asthma in adults and children wearing masks while at rest, with median SpO2 98% in both groups. There was no difference in oxygen saturation or reported level of dyspnea between the children with asthma and children without asthma performing the 6-minute walk test while wearing masks. Median SpO2 levels were at or near 99% in the asthma and non-asthma groups at all time points. Median PDS scores were similar between the asthma and non-asthma groups. Conclusion: Mask use did not affect SpO2 in adults and children at rest or in children performing low-to-moderate intensity exercise. These findings were consistent in those with and without asthma.

A fase terminal do filho com câncer: percepções dos profissionais hospitalares / The terminal phase of children with cancer: perceptions of hospital professionals / La fase terminal del hijo con cáncer: percepciones de los profesionales del hospital

O confronto com o câncer de um filho e a percepção da sua morte como inevitável dão lugar a experiências parentais relevantes para a pesquisa científica. Este estudo teve como objetivo investigar, por meio da percepção dos profissionais hospitalares, o modo como os pais experienciam a fase terminal e fim de vida do filho com câncer para melhor compreender os processos psicoemocionais experienciados por esses pais diante da cronicidade da doença e da morte do filho. No sentido de alcançar esse objetivo, realizou-se um estudo qualitativo de tipo fenomenológico envolvendo 17 profissionais de dois hospitais portugueses de referência em oncologia pediátrica. Os dados foram recolhidos com recurso a um guia de entrevista semiestruturada. Na percepção dos profissionais hospitalares, os resultados evidenciam que esses pais experienciam múltiplas dificuldades e preocupações na fase terminal da doença do filho e no pós-morte, bem como um sofrimento extremo e desestruturação biopsicossocial e espiritual na família. O conhecimento aprofundado da fenomenologia desses processos é essencial para o desenho e a implementação de intervenções emocionais, cognitivas, comportamentais e sociais mais ajustadas às dificuldades e preocupações parentais vividas no fim de vida e pós-morte.(AU)

Coping with children's cancer and the perception of their inevitable death give rise to parental experiences that are important to study. This study aimed to investigate, based on hospital professionals' perspectives, how parents experience the terminal phase and end of life of their children suffering from cancer to better understand the psycho-emotional processes these parents experienced in face of the chronicity of the disease and their children's death. To achieve this objective, a qualitative phenomenological study was carried out involving 17 professionals of two Portuguese hospitals that are reference in pediatric oncology. Data were collected using a semi-structured interview guide. From the perspective of hospital professionals, results show that these parents experience multiple difficulties and concerns in the terminal phase of their children's disease and postmortem, as well as the extreme suffering and biopsychosocial and spiritual disruption of the family. A deeper understanding of the phenomenology of these processes is essential to design and implement better adjusted emotional, cognitive, behavioral, and social interventions aimed at the parental difficulties and concerns experienced at the end of life and after death.(AU)

El conocimiento en profundidad de la fenomenología de estos procesos es esencial para elaborar e implementar intervenciones emocionales, cognitivas, conductuales y sociales más acordes a las dificultades y preocupaciones parentales que se experimentan al final de la vida y la postmuerte.(AU)

[Comprehensive assessment of congestion in heart failure]. / Evaluación integral de la congestión en insuficiencia cardíaca.

The complex, heterogeneous, and dynamic interaction between the interstitial and intravascular fluid compartments is one of the main reasons for the wide variability in the distribution and severity of congestion among patients with acute heart failure. The "hemodynamic congestion" often goes undetected clinically; as opposed to "clinical congestion", which occurs later and is evidenced by dyspnea and orthopnea, rales, peripheral edema, and jugular venous distension. Clinical signs, chest X-ray, brain natriuretic peptide (BNP) or N-terminal-proBNP (NT-proBNP), central venous pressure (CVP), echocardiogram, inferior vena cava (IVC) diameter, and pulmonary wedge pressure are the most commonly used elements to assess congestion. Other alternatives are pulmonary and visceral ultrasound (VEXUS), CA 125 and other markers, and recently, the CardioMems system.

La interacción compleja, heterogénea y dinámica entre los compartimentos de líquido intersticial e intravascular es una de las principales razones que explican la amplia variabilidad en la distribución y gravedad de la congestión entre los pacientes con insuficiencia cardíaca descompensada. La "congestión hemodinámica" suele pasar desapercibida clínicamente; en oposición a la "congestión clínica", que ocurre más tarde y se evidencia por disnea y ortopnea, estertores pulmonares, edema periférico y distensión venosa yugular. Los signos clínicos, la radiografía de tórax, el péptido natriurético cerebral (brain natriuretic peptide o BNP) o la porción terminal N del pro BNP (NT-proBNP), la presión venosa central (PVC), el ecocardiograma, el diámetro de la vena cava inferior (VCI) y la presión de enclavamiento pulmonar son los elementos más utilizados para evaluar la congestión. Otras alternativas son el ultrasonido pulmonar y visceral (VEXUS), el CA 125 y otros marcadores y, recientemente, el sistema CardioMems.

[Pathogenesis and assessment of exertional dyspnea in chronic obstructive pulmonary disease].

Chronic obstructive pulmonary disease (COPD) is a common respiratory system disease that seriously affects the quality of life and has a high mortality rate. Exertional dyspnea is the most common symptom in COPD patients with complexed pathogenesis and limited therapeutic drug effects. In this paper, we reviewed the relevant mechanisms and assessment, in order to improve understanding of the pathogenesis of exertional dyspnea in COPD, to emphasize the importance of accurate assessment, and to explore effective interventions that can effectively improve the degree of dyspnea and even delay or reverse the decline in lung function.

Current cough and sputum assessed by the cough and sputum assessment-questionnaire (CASA-Q) is associated with quality of life impairment in cystic fibrosis.

BACKGROUND: Cough and sputum are major symptoms in cystic fibrosis (CF) that contribute to the impairment of quality of life. METHODS: This prospective single centre cross-sectional pilot study aimed to evaluate the results of a self-administered questionnaire assessing cough and sputum symptoms (2 domains), and their impact (2 domains) on daily activities in the previous week, named the Cough and Sputum Assessment Questionnaire (CASA-Q) in CF adult patients at stable state, and to analyse associations with clinical, functional, microbiological, radiological data, and two quality of life scales: the Cystic Fibrosis Questionnaire Revised (CFQ-R) and the Saint George Respiratory Questionnaire (SGRQ). RESULTS: Forty-eight patients were included in this analysis (69% men; median age of 27.8 ± 8.1 years; median body mass index of 21.8 + 3.3 kg/m²; mean FEV1 of 64 ± 30% of the predicted value). The mean values of the CASA-Q domains were 58 ± 23 for cough symptoms, 77 ± 24 for cough impact, 62 ± 25 for sputum symptoms and 84 ± 21 for sputum impact. Impairment in CASA-Q cough and sputum domains was associated with dyspnea mMRC scale (p < 0.005 for all 4 domains of CASA-Q) and exacerbations in the previous year (p < 0.05 for CASA-Q symptoms domains). We also found correlations between all domains of the CASA-Q and quality of life questionnaires including SGRQ (p < 0.001) and to a lesser extend CFQ-R. We identified a clinical phenotype (female gender, ΔF508 heterozygous mutation, dyspnea mMRC scale) associated with an impairment of CASA-Q score and quality of life using a 2-step cluster analysis. CONCLUSIONS: CASA-Q allows the assessment of cough and sputum in CF adult patients and is associated with quality of life impairment. This simple easy-to-use tool could be used in routine clinical practice and in clinical studies to assess cough and sputum in CF patients. TRIAL REGISTRATION: The study was registered on ClinicalTrials.gov (NCT02924818, first posted on 5th October 2016).

Assessment of dyspnea, ADL, and QOL in the perioperative period in lung cancer patients treated with minimally invasive surgery.

OBJECTIVE: Patients with lung cancer generally undergo minimally invasive surgery, such as video-assisted thoracoscopic surgery (VATS). This study examined the changes in health conditions and symptoms of patients with lung cancer using the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC QLQ) C-30 questionnaires after surgery. METHODS: This was a longitudinal descriptive study. One hundred and three patients with lung cancer who underwent lung resection at Tokushima University Hospital between 2012 and 2021 were eligible. They completed EORTC QLQ-C30, QLQ-LC13, the Cancer Dyspnea scale (CDS), and pulmonary-ADL (P-ADL) before and 1, 3, and 6 months after surgery. RESULTS: Regarding functional scale scores, impairments in physical and role functions persisted for 6 months after surgery. In symptom scale scores, fatigue, pain, dyspnea, and appetite loss continued for 6 months after surgery. In CDS, sense of effort, discomfort, and total dyspnea scale scores were elevated for 6 months after surgery. In P-ADL, most ADL were impaired 1 month after surgery, but recovered by 3 months. The dyspnea index of ADL was lower for 6 months after surgery. CONCLUSIONS: Impairments in health conditions and symptoms persisted for 6 months after surgery despite its minimally invasive nature.

Assessment of dyspneic sensation in patients with type 2 diabetes.

Introduction: Individuals with type 2 diabetes (T2D) should be considered a susceptible group for pulmonary dysfunction. So, we aimed to evaluate the sensation of breathlessness in this population by administering two well-validated questionnaires. Methods: This is a crosssectional study with 592 people without known respiratory disease (353 with T2D) who answered the modified Medical Research Council (mMRC) questionnaire. In addition, 47% also responded to the St George Respiratory Questionnaire, a specific instrument designed to be applied to patients with obstructive airway disease. Results: Patients with T2D showed a higher mMRC score in comparison to the control group [1.0 (0.0 - 4.0) vs. 0.0 (0.0 - 4.0), p<0.001]. A higher prevalence of subjects with mMRC ≥2 was observed in T2D that in the control group (20.2% vs. 11.6%, p=0.004). Participants with T2D and mMRC ≥2 showed a higher HbA1c (8.2 ± 1.6% vs. 7.8 ± 1.6%, p=0.048), longer T2D evolution and higher prevalence of nephropathy. In the multivariate analysis, the presence of T2D [OR=1.95 (1.19 to 3.22), p=0.008] in all the population, and HbA1c [OR=1.19 (1.01 to 1.41), p=0.034] and the presence of diabetic nephropathy [OR=2.00 (1.14 to 3.52), p=0.015] in patients with T2D, predicted a mMRC ≥2. Finally, no differences were observed regarding the SGRQ score among groups. Conclusions: Patients with T2D showed a greater sensation of dyspnea than subjects with normal carbohydrate metabolism. Risk factors included poor metabolic control and the presence of renal disease.
