How people with chronic obstructive pulmonary disease perceive their illness: a qualitative study between mind and body.

BACKGROUND: Although many studies on people with Chronic Obstructive Pulmonary Disease (COPD) have examined the mutual impact of physical status and emotional experience, there is limited knowledge about the way COPD people first-hand perceive their condition. This study was designed to investigate the illness perceptions of the patients and, secondarily, to explore their beliefs about the mind-body relationship. METHODS: This qualitative study has exploited an ad-hoc semi-structured interview to collect personal perspectives of participants on their illness. Twenty-seven patients (15 males and 12 females), with a mild to severe COPD, were recruited within the Respiratory Rehabilitation Unit of Don Carlo Gnocchi Foundation, in Milan. The thematic analysis of the interviews' content was facilitated by NVivo (12th version, QSR International®). RESULTS: The thematic analysis of the corpus resulted in four master themes. Illness experience has been considered the primary one. Indeed, dealing with COPD every day allows these people to portray a specific representation of the mind-body relationship, to gain a certain degree of expertise and to develop a perspective on the future. CONCLUSIONS: Individual perceptions of the illness vary among people with COPD, but some common experiences characterize them. Many patients share a profound belief that their mental state and their physical symptoms are highly interrelated.

Acceptance and adherence to non-invasive positive pressure ventilation in people with chronic obstructive pulmonary disease: a grounded theory study.

Introduction: Non-Invasive Positive Pressure Ventilation (NPPV) is an established treatment for people with Chronic Obstructive Pulmonary Disease (COPD), but it is often improperly used or rejected. The patterns of acceptance and adherence to NPPV, conceiving constraints, and strengths related to its adaptation have not been explored from a qualitative perspective yet. Objectives: This study aims to qualitatively explore patterns of adaptation to NPPV in people affected by COPD and to identify the core characteristics and the specific adaptive challenges during the adaptation process. Methods: Forty-two people with moderate or severe COPD were recruited and 336 unstructured interviews were conducted. A Constructivist Grounded Theory was used to gather and analyze data: the transcriptions were mutually gathered in open, selective, and theoretical phases, with open, selective, and theoretical coding, respectively. Results: The analysis resulted in a non-linear and dynamic process, characterized by three phases: deciding, trying NPPV, and using NPPV. The patterns revealed that positive and negative NPPV experiences, together with beliefs, emotions, stressful mental states, and behaviors result in different acceptance and adherence rates. Discussions: These findings may be helpful to implement new care strategies to promote acceptance and adherence to NPPV.

Intermittent abdominal pressure ventilation management in neuromuscular diseases: a Delphi panel Consensus.

BACKGROUND: Intermittent abdominal pressure ventilator (IAPV) use started in the 1930s for ventilatory assistance with muscular dystrophy patients. Later, the device was perfected and expanded for other neuromuscular disorders (NMD). In recent years, the morbidity and mortality tracheotomies and trach tubes related renewed the interest around IAPV. However, there are no guidelines for its use. This study aimed to establish a consensus among physicians involved in its practice to provide IAPV suggestions for the treatment of patients with NMD. METHOD: A 3-step modified Delphi method was used to establish consensus. Fourteen respiratory physicians and one psychiatrist with strong experience in IAPV use and/or who published manuscripts on the topic participated in the panel. A systematic review of the literature was carried out according to the PRISMA to identify existing evidence on IAPV for patients with neuromuscular disorders. RESULTS: In the first round, 34 statements were circulated. Panel members marked 'agree' or 'disagree' for each statement and provided comments. The agreement was reached after the second voting session for all 34 statements. CONCLUSIONS: Panel members agreed and IAPV indications, parameter settings (including procedure protocol), potential limitations, contraindications, complications, monitoring, and follow-up are described. This is the first expert consensus on IAPV.

Characteristics, Components, and Efficacy of Telerehabilitation Approaches for People with Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is at the top of the list of non-communicable diseases with related rehabilitation needs. Digital medicine may provide continuative integrated intervention, overcoming accessibility and cost barriers. METHODS: We systematically searched for randomized controlled trials on telerehabilitation (TR) in people with COPD to profile the adopted TR strategies, focusing on TR models and the main rehabilitation actions: monitoring and assessment, decision, and feedback. Additionally, a meta-analysis was run to test the TR effect on functional capacity, dyspnea, and quality of life compared to no intervention (NI) and conventional intervention (CI). RESULTS: Out of the 6041 studies identified, 22 were eligible for the systematic review, and 14 were included in the meta-analyses. Results showed a heterogeneous scenario in terms of the TR features. Furthermore, only a small group of trials presented a comprehensive technological kit. The meta-analysis highlighted a significant effect of TR, especially with the asynchronous model, on all outcomes compared to NI. Moreover, a non-inferiority effect of TR on functional capacity and quality of life, and a superiority effect on dyspnea compared to CI were observed. Finally, the studies suggested a high rate of TR adherence and high safety level. CONCLUSIONS: TR is an effective strategy to increase and maintain functional capacity, breath, and quality of life in people with COPD. However, a consensus on the essential elements and features of this approach needs to be defined, and the effect of long-term maintenance merits further investigation.

Telerehabilitation Approaches for People with Chronic Heart Failure: A Systematic Review and Meta-Analysis.

INTRODUCTION: Telerehabilitation (TR) for chronic heart failure (CHF) allows for overcoming distance barriers and reducing exacerbations. However, little is known about TR descriptors, components, and efficacy in CHF. METHODS: This work systematically reviewed the TR strategies of randomized controlled trials in people with CHF. A meta-analysis was run to test its effect on exercise capacity and quality of life compared to no rehabilitation (NI) and conventional intervention (CI). RESULTS: Out of 6168 studies, 11 were eligible for the systematic review, and 8 for the meta-analysis. TR intervention was individual and multidimensional, with a frequency varying from 2 to 5 times per 8-12 weeks. The TR components mainly included an asynchronous model, monitoring/assessment, decision, and offline feedback. A few studies provided a comprehensive technological kit. Minimal adverse events and high adherence were reported. A large effect of TR compared to NI and a non-inferiority effect compared to CI was registered on exercise capacity, but no effects of TR compared to NI and CI on quality of life were observed. CONCLUSIONS: TR for people with CHF adopted established effective strategies. Future interventions may identify the precise TR dose for CHF, technological requirements, and engagement components affecting the patient's quality of life.

HLA Allele Frequencies and Association with Severity of COVID-19 Infection in Northern Italian Patients.

HLA allelic distribution was analysed in a cohort of 96 Northern Italian subjects (53M/43F) (mean age 59.9 ± 13.3 years) from Lombardy who developed COVID-19 during the first two pandemic waves to investigate possible correlations between HLA molecules and disease severity. An important role of HLA- B and HLA-C loci in modulating the clinical severity of COVID-19 disease was identified. In particular, the HLA-B07 supertype was observed to be associated with a significant risk for severe disease; conversely, the HLA-B27 supertype and C*12:02 allele played a protective role as they were associated with milder disease. These associations were confirmed after applying a multinomial regression analysis to adjust the correlation for age, gender and comorbidities with COVID-19 severity. Though the power of results is limited by the small sample size, data herein contribute to shedding light on the role played by genetic background in COVID-19 infection.

Characterization of the COPD Salivary Fingerprint through Surface Enhanced Raman Spectroscopy: A Pilot Study.

Chronic Obstructive Pulmonary Disease (COPD) is a debilitating pathology characterized by reduced lung function, breathlessness and rapid and unrelenting decrease in quality of life. The severity rate and the therapy selection are strictly dependent on various parameters verifiable after years of clinical observations, missing a direct biomarker associated with COPD. In this work, we report the methodological application of Surface Enhanced Raman Spectroscopy combined with Multivariate statistics for the analysis of saliva samples collected from 15 patients affected by COPD and 15 related healthy subjects in a pilot study. The comparative Raman analysis allowed to determine a specific signature of the pathological saliva, highlighting differences in determined biological species, already studied and characterized in COPD onset, compared to the Raman signature of healthy samples. The unsupervised principal component analysis and hierarchical clustering revealed a sharp data dispersion between the two experimental groups. Using the linear discriminant analysis, we created a classification model able to discriminate the collected signals with accuracies, specificities, and sensitivities of more than 98%. The results of this preliminary study are promising for further applications of Raman spectroscopy in the COPD clinical field.

Identification of the Raman Salivary Fingerprint of Parkinson's Disease Through the Spectroscopic- Computational Combinatory Approach.

Despite the wide range of proposed biomarkers for Parkinson's disease (PD), there are no specific molecules or signals able to early and uniquely identify the pathology onset, progression and stratification. Saliva is a complex biofluid, containing a wide range of biological molecules shared with blood and cerebrospinal fluid. By means of an optimized Raman spectroscopy procedure, the salivary Raman signature of PD can be characterized and used to create a classification model. Raman analysis was applied to collect the global signal from the saliva of 23 PD patients and related pathological and healthy controls. The acquired spectra were computed using machine and deep learning approaches. The Raman database was used to create a classification model able to discriminate each spectrum to the correct belonging group, with accuracy, specificity, and sensitivity of more than 97% for the single spectra attribution. Similarly, each patient was correctly assigned with discriminatory power of more than 90%. Moreover, the extracted data were significantly correlated with clinical data used nowadays for the PD diagnosis and monitoring. The preliminary data reported highlight the potentialities of the proposed methodology that, once validated in larger cohorts and with multi-centered studies, could represent an innovative minimally invasive and accurate procedure to determine the PD onset, progression and to monitor therapies and rehabilitation efficacy.

Thunderstorm-asthma, two cases observed in Northern Italy.

Thunderstorm asthma is a rare event: in this letter we describe two cases observed during the same month of 2018 at an Italian Emergency department, assessed by the same medical team and according to the same methodology and approach. Given the infrequency of such a phenomenon and the debate around its nature, frequency, and - at times - existence, we strongly believe it is important for all specialists who observe such cases to report them, building an evidence base to expand its knowledge and understanding.

Psychological Support for Health Professionals: An Interpretative Phenomenological Analysis.

Background: The work of health care professionals (HCPs) exposes them to emotionally difficult situations, anxiety, suffering and death, so they are at risk of burnout. Objectives: To describe HCPs' experiences of a psychological support intervention and its influence on the daily work of a sample caring for patients with neuromuscular and chronic respiratory illnesses. Methods: This exploratory, descriptive, qualitative study was carried out at the Respiratory Rehabilitation Unit of IRCCS Santa Maria Nascente, in Milan, Italy. Semi-structured interviews with a purposive sample of 10 HCPs were subjected to interpretative phenomenological analysis (IPA). Results: Five related themes emerged: psychological support; repeating the experience; relationships; the role of homework; competences. HCPs perceived that the intervention influenced their daily life, giving them a secure base and a new perspective on their professional role. Conclusion: Psychological support interventions may not be appropriate for all HCPs, but they may help some HCPs to handle the demands of a stressful work life. Further studies are needed to determine its efficacy in reducing stress and prevent burnout.
