The Saudi thoracic society guidelines for vaccinations in adult patients with chronic respiratory diseases

Abstract: Adult patients with chronic respiratory diseases (CRDs) are considered high risk group who are more likely to experience worse clinical outcomes if they acquire viral or bacterial infections. Vaccination is the best preventive tool to reduce the risk of infection and disease occurrence and to reduce the level of severity of complications associated with the various vaccine-preventable infections. These guidelines were developed by the Saudi Thoracic Society task force to emphasize the critical importance of improving the vaccine coverage rates in adult patients with CRD. They are intended to serve as a reference for healthcare practitioners managing CRD patients. The guidelines aimed to review the current knowledge related to vaccination efficacy in adult patients with CRD, based on the recent evidence and recommendations. Integrating the administration of the recommended vaccines in routine healthcare, such as during outpatient visits or before hospital discharge, is crucial for improving the vaccination rates in high-risk patients. The key strategies to address this public health priority include simplifying vaccination guidelines to enhance their accessibility and implementation by healthcare providers, increasing awareness in both the patients and healthcare providers that vaccines are not only intended for children. Additional strategies include maintaining continuous surveillance and advance research to discover novel vaccines. This approach aims to expand the range of preventable diseases and improve overall health and well-being. Vaccine hesitancy remains a significant challenge that necessitates a clear understanding of the community concerns. Providing appropriate education and communication, as well as addressing these concerns, are the crucial steps toward improving vaccine acceptance and uptake. By implementing these guidelines and multifaceted strategies, healthcare systems can optimize vaccine coverage and protection for patients with CRD, reduce the burden of vaccine-preventable complications, and improve the clinical outcomes in this vulnerable population.

Personality and health behavior changes after pulmonary rehabilitation: A longitudinal observational study.

Pulmonary rehabilitation (PR) is the gold standard treatment for improving the health status of individuals with chronic respiratory diseases (CRD). However, to achieve lasting results, the adoption and maintenance of a physically active lifestyle are necessary. Unfortunately, the trajectories of change in physical activity (PA) and sedentary behavior (SB) following PR are marked by a high degree of heterogeneity between patients. This study aimed to better understand the factors underlying this variability by investigating the role played by the personality as defined by the five-factor model. Eighty eight CRD patients were assessed on personality upon PR admission (Time 1). PA and SB were assessed at Time 1 and 6 months post-PR (Time 2) using questionnaires. Multiple regression analyses revealed that "healthy neuroticism" is associated with an increase in PA 6 months after PR (β = .20, p < .05) independently of the PA at Time 1. A high level of neuroticism, when it is paired with a low level of conscientiousness, is related to an increase in SB 6 months after PR (β = -.20, p < .01), when the SB and exercise tolerance at Time 1 were controlled for. These findings highlight that investigating the interaction between personality traits is relevant to a better understanding of the interindividual differences in changes in PA and SB after PR in patients with CRD. The behavioral effects of PR could be improved if patients' personality traits were taken into account in the design of behavior-change interventions.

Trends in hospitalisations for lower respiratory infections after the COVID-19 pandemic in France

We aimed to evaluate the impact of the pandemic and post-pandemic periods on hospital admissions for LRTI, with a focus on patients with chronic respiratory disease (CRD). From July 2013 to June 2023, monthly numbers of adult hospitalisations for LRTI (excluding SARS-CoV-2) were extracted from the French National Hospital Discharge Database. They were modelled by regressions with autocorrelated errors. Three periods were defined: (1) early pandemic and successive lockdowns; (2) gradual lifting of restrictions and widespread SARS-CoV-2 vaccination; (3) withdrawal of restriction measures. Pre-pandemic incidence was 96 (90.5 to 101.5) per 100,000 population. Compared with the pre-pandemic period, no more seasonality and significant reductions were estimated in the first two periods: -43.64% (-50.11 to -37.17) and -32.97% (-39.88 to -26.05), respectively. A rebound with a positive trend and a seasonal pattern was observed in period 3. Similar results were observed for CRD patients with no significant difference with pre-pandemic levels in the last period (-9.21%; -20.9% to 1.67%), albeit with differential changes according to the type of CRD. COVID-19 pandemic containment measures contributed to changes in LRTI incidence, with a rapid increase and return to a seasonal pattern after their lifting, particularly in patients with CRD.

Perception and Impact of Long-Term Oxygen Therapy on the Functioning and Quality of Life of Patients With Chronic Respiratory Disease: A Mixed-Method Study.

Introduction In patients with severe chronic pulmonary diseases, there is often a need for oxygen therapy to continue after discharge from hospitalization. Long-term oxygen therapy (LTOT) has been shown to significantly reduce mortality in such patients and improve longevity by helping to correct oxygen deficiency in the bloodstream and prevent organ failure and the development of cor pulmonale (right-sided heart failure). Therefore, considering the sociocultural background of India, the objective of the present study was to evaluate patients' perceptions of LTOT using semi-structured interviews, to evaluate patients' perceptions of activities and participation, and to evaluate the quality of life (QOL) of patients with LTOT. Methodology A mixed-method study was performed at a tertiary care hospital for six months. Twenty-four chronic respiratory patients were included in the present study. The patients' perception was evaluated about LTOT using semi-structured interviews, activities, and participation using a validated activity and participation checklist and the QOL of patients with LTOT using the World Health Organization Quality of Life Brief Version (WHOQOL-BREF) questionnaire. Results Twenty-four patients were interviewed and transcripts were analyzed through thematic analysis. Descriptive statistical analysis was performed for activity and participation along with QOL.The mean age of the patients involved was 58.5 ± 9.54 years, which involved a maximum of male patients consisting of 13 (54.2%) in comparison to female patients. The duration of oxygen use in months was 31.4 ± 29.4, the daily oxygen usage in hours was 17.3 ± 6.6, and the oxygen flow rate (L/min) was found to be 2.3 ± 0.97 at rest and 3.6 ± 1.4 on activity. In addition, the oxygen use by the patients was preferable as prescribed by 15 (62.5%) patients. Patients' perspectives on LTOT demonstrated that 10 (41.7%) patients perceived oxygen as relieving symptoms while most patients used oxygen during walking indoors activity involving 22 patients (91.7%), with 17 (77.3%) reporting improved ability and five (22.7%) facing obstacles. Instrumental activities involving walking shorter distances (less than 1 km) involved a high usage of oxygen with 20 patients (83.3%) using it, where 15 (75%) found it beneficial, three (15%) encountered obstacles, and two (10%) noted no effect from its use. Social interaction found that only one patient (4.20%) used oxygen at work, finding it helpful, but the majority, 20 (83.4%), did not go to work at all. Moreover, oxygen usage during transportation reported that travel using private vehicles involved a maximum of patients (16, 66.7%). Furthermore, for inquiries related to QOL, the results demonstrated that for the four domains of WHOQOL-BREF, consisting of physical health, psychological, social relationships, and environment, the mean values were found to be 48.33 ±10.66, 54.79 ± 13.7, 55.75 ±11.1, and 60.25 ± 12.6, respectively. Conclusion LTOT has been perceived to be a life-saving intervention by majority of the chronic respiratory disease patients of increased severity. Patients experienced various issues in daily activities and participation, which have affected their QOL. Overall, a lack of awareness and knowledge regarding the purpose, dosage, benefit, and usage of oxygen therapy was found to be evident and needs to be focused.

Fecal microbiome extract downregulates the expression of key proteins at the interface between airway remodelling and lung cancer pathogenesis in vitro

Lung cancer (LC) is the leading cause of cancer-related mortality, and it is caused by many factors including cigarette smoking. Despite numerous treatment strategies for LC, its five-year survival is still poor (<20 %), attributable to treatment resistance and lack of early diagnosis and intervention. Importantly, LC incidence is higher in patients affected by chronic respiratory diseases (CRDs) such as asthma and chronic obstructive pulmonary disorder (COPD), and LC shares with other CRDs common pathophysiological features including chronic inflammation, oxidative stress, cellular senescence, and airway remodelling. Remodelling is a complex process resulting from the aberrant activation of tissue repair secondary to chronic inflammation, oxidative stress, and tissue damage observed in the airways of CRD patients, and it is characterized by irreversible airway structural and functional alterations, concomitantly with tissue fibrosis, epithelial-to-mesenchymal transition (EMT), excessive collagen deposition, and thickening of the basement membrane. Many processes involved in remodelling, particularly EMT, are also fundamental for LC pathogenesis, highlighting a potential connection between CRDs and LC. This provides rationale for the development of novel treatment strategies aimed at targeting components of the remodelling pathways. In this study, we tested the in vitro therapeutic activity of rat fecal microbiome extract (FME) on A549 human lung adenocarcinoma cells. We show that treatment with FME significantly downregulates the expression of six proteins whose function is at the forefront between airway remodelling and LC development: Snail, SPARC, MUC-1, Osteopontin, MMP-2, and HIF-1α. The results of this study, if confirmed by further investigations, provide proof-of-concept for a novel approach in the treatment of LC, focused on tackling the airway remodelling mechanisms underlying the increased susceptibility to develop LC observed in CRD patients.

Using spirometry for screening and diagnosis of chronic respiratory diseases in primary health care: findings from a community health project in rural India

Background Chronic respiratory diseases (CRDs) such as Chronic obstructive pulmonary disease (COPD), Asthma and post-tuberculosis lung disease (PTLD) are a growing public health concern in India. Early diagnosis and management of CRDs require a good quality spirometry test, a technician to conduct spirometry and a chest physician to interpret the results. In India, these are not available at the primary care level. This study reports the feasibility of a large-scale CRD diagnosis and management program in primary care using a unique point-of-care spirometry solution, Briota PFT in a Box™. # Methods A community-based cross-sectional study was conducted among 15,602 adults in Dindori Taluka (subdivision), Nashik, Maharashtra state. This study was part of a holistic CRD diagnosis and management program SAVE™ (Spirometry Assisted Virtually Early). Make In India point of care solution Briota PFT in a Box™ was used. A House‐to‐house community-based assessment checklist (CBAC) survey, 4-parameter spirometry test, 15-parameter pre and post-bronchodilator spirometry test and a software-assisted medical examination by the medical officer at primary care were conducted. Software was used to generate CRD diagnosis and lung health score (LHS™). The diagnosis was verified by the chest physician. Confirmed diagnosed patients were provided treatment and offered a patient support program. Interviews were conducted with the patients, nurses, doctors and public health officials for understanding feasibility and documenting learning from program SAVE™. # Results Out of 15,602 adults surveyed, total 4,937 (31.6%) were identified as “CRD high risk”. 1231 participants based on medical examination, spirometry tests and software analysis were identified as CRD candidates by medical officers at primary care. 1154 participants out of 15,602 (7.4%) were confirmed diagnosed as CRD patients post independent evaluation by chest physicians. At the time of follow-up, 537 patients (75% of 712 patients enrolled in patient support program) reported improvement in symptoms and high satisfaction with the program. District health officer, Medical officers, nurses, Accredited Social Health Activist (ASHA) from the primary health care centers confirmed ease of use and feasibility of using Briota PFT in a Box™ in program SAVE™. Outcome and learning from program SAVE™ was documented and submitted to Ministry of Health and Family Welfare Government of India. # Conclusions CRD diagnosis and management in large scale settings in primary healthcare level using a point of care spirometry solution Briota PFT in a Box™ is highly feasible.

Fragilidad en pacientes con enfermedades respiratorias crónicas: ¿cómo modificarla?

Frailty is a multidimensional state characterized by a decrease in physiological reserves and resistance to stressors. Its physical dimension is highly recognized and increases vulnerability for developing greater dependency and/or death. Patients with chronic respiratory diseases have a higher risk of developing frailty and among the risk factors are comorbidities, smoking, low levels of physical activity, exacerbations of their underlying pathology, recurrent hospitalizations, poor nutrition and polypharmacy. Frailty is a dynamic and modifiable process. Timely referral to pulmonary rehabilitation programs is one of the different treatments available. The present article describes fragility in chronic respiratory disease patients, and offers tools to evaluate and modify it.

Prevalence of frailty among chronic respiratory disease patients.

Although frailty is one of the aging syndromes, it can occur at a younger age and in individuals with organ diseases. Identifying frailty and pre-frailty in patients with chronic respiratory diseases (CRDs) is an emerging assessment in the field of pulmonary medicine and rehabilitation. The aim of this study was to find out the prevalence of frailty among chronic respiratory disease patients. A single centre cross-sectional survey study with a total population of 381 patients, adults aged 18-90 years presenting to the pulmonology OPD was included based on the inclusion and exclusion criteria. Primary data collected were demographics, medical history, including comorbidities, use of long-term oxygen therapy (LTOT), BiPAP (Bilevel Positive Airway Pressure), previous hospital admissions, medication history and frailty assessment were done using the Fried frailty index. Univariate analysis showed that sex, ECHO abnormality, patients using LTOT, BiPAP, home nebulizers and patients who did not attend the pulmonary rehabilitation programme had a significant association with frailty. Multivariate analysis showed that female sex, LTOT use and older age were significantly associated with frailty. Frailty is frequent in CRD patients regardless of age. The prevalence of frailty has an association with female sex, patients using LTOT, and home BiPAP.

Effect of Diet Counseling on Nutritional Status of Chronic Respiratory Diseases Patients Enrolled in the Pulmonary Rehabilitation Program in a Teaching Hospital: A Pre-Post Intervention Study.

We conducted the study to assess the effect of patient-tailored diet counseling on the nutritional status of chronic respiratory disease (CRD) patients under the pulmonary rehabilitation program from June 2021-May 2022. These patients completed 2 months of patient-tailored diet counseling sessions under the pulmonary rehabilitation program, which consisted of 4-5 interactive diet counseling sessions fortnightly. The pre- and postassessment was done using standardized outcomes: Malnutrition Universal Screening Tool (MUST), body mass index (BMI), and ideal body weight. The study enrolled 110 CRD patients. There was a statistically significant improvement in pre- and postassessment in MUST score, appetite, and unintentional weight loss (P < 0.001). Most of the patient's BMI normalized. In prenutritional assessment, most of the patients were malnourished and in postassessment, the number of malnourished and anemic patients was reduced. This study concludes that nutritional counseling effectively improves nutritional status and anemia.

Implementation of virtual pulmonary rehabilitation during the COVID-19 pandemic: Experiences and perceptions of patients and healthcare providers

BackgroundPulmonary rehabilitation (PR) plays an important role in the management of symptomatic patients with chronic respiratory diseases (CRD). While studies have investigated the feasibility and efficacy of virtual PR (VPR), it is important to understand the experiences of patients and healthcare providers (HCPs) during the rapid digital health transformation that occurred in the COVID-19 pandemic. ObjectivesTo explore the experiences and perspectives of patients and HCPs who participated in VPR during the pandemic. MethodsSemi-structured interviews were conducted with CRD patients and HCPs. This study used a qualitative descriptive approach and a team-based inductive thematic analysis. ResultsParticipants included 11 HCPs (7 female; 29–55 years) and 19 CRD patients (11 male; 62–83 years; 15 COPD, 4 COPD/ILD). Three major themes and 10 subthemes were identified: i) the pandemic response: a ‘trial by fire’ (navigating uncertainty, emotional impact of change, shifting practice amid complexity); ii) beyond the emergency: navigating a ‘new normal’ (eligibility and assessment for VPR, virtual exercise, virtual education and resources, clinical supervision and patient safety); and iii) care beyond boundaries: the implications of using technology for PR (benefits and limitations of technology, psychosocial implications, VPR in the future). ConclusionThe pivot to VPR was acknowledged as positive by both patients and HCPs although both groups were mindful of the implementation challenges. These findings provide insight into the experience of HCPs and patients in introducing VPR in response to the pandemic and will inform future implementation of VPR for individuals with CRD.

Impact of pulmonary rehabilitation on lung functions and quality of life in chronic respiratory disease patients

Patients with chronic pulmonary disease commonly present with dyspnea, cough, fatigue, physical limitations, and low Quality-of-Life (QoL). With these morbidities and physical limitations, it may be difficult to perform their day-to-day activities. The London Chest Activity Daily Living (LCADL) scale assesses the self-reported dyspnea of patients with chronic respiratory disease during Activities of Daily Living (ADL). The study was designed to assess the impact of pulmonary rehabilitation on the dyspnea grade (mMRC scale), the Quality-of-Life parameters viz LCADL scale, 6 Minute Walk Test (6MWT) and lung functions (FEV1 &amp; FVC).The study is a retrospective observational study conducted over a period of 1 year, at the Department of Pulmonology, Bhakti Vedanta Hospital &amp; Research Institute. Patients with different pulmonary conditions such as Chronic Obstructive Pulmonary Disease (COPD), Interstitial Lung Disease (ILD), Post-covid Lung Dysfunction, etc. were enrolled in the study. A total of 80 patients were referred to Pulmonary Rehabilitation (PR). Out of which, 40 patients completed an 8-week program. The distribution of the study population was as follows: 18 patients with COPD, 13 patients with ILD, 9 patients with other pulmonary diseases. 15 patients required oxygen support where oxygen saturation (SpO2) was &amp;#60; 90% at baseline at room air. The outcome measures were assessed in these patients at the time of enrollment (Week 0) and at the end of the program (Week 8).Overall, the statistically significant difference noted in Quality-of-Life parameters like LCADL score, mMRC, 6MWT, and lung functions (FEV1, FVC) with an 8-week Pulmonary Rehabilitation program.The p-value (&amp;#60; 0.001) was found in London Chest Activity Daily Living (LCADL) score. Domestic, physical activity had better scores with respect to all parameters after completion of the 8-week Pulmonary Rehabilitation (PR) program. The dyspnea grade on the mMRC scale improved from 1.9 ± 0.591 to 0.45 ± 0.50. The p-value was statistically significant (p &amp;#60; 0.001). 6 MWT distance was improved from 169.5 meters to 324.5 meters at the completion of 8-weeks, the mean difference was 155 meters which was found to be statistically significant. The p-value (&amp;#60; 0.001) was found in 6MWT distance. In lung functions, FEV1 improved from 52.30 % to 56.73 % of predicted and FVC improved from 56.20 % to 58.20 % of predicted. The mean difference of FEV1 and FVC was 4.43 to 2.0, respectively. : An 8-week supervised pulmonary rehabilitation program has demonstrated that the inclusion of pulmonary rehabilitation, not only reduces the symptoms but also improves the exercise capacity and add significant positive effect on the quality of life as well as lung functions in patients with chronic respiratory disease.

"In their own words": delineating the contours of dyspnea invisibility in patients with advanced chronic obstructive pulmonary disease from quantitative discourse analysis

BackgroundDyspnea 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.MethodsWe 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).ResultsClass#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.ConclusionsLexicometry confirms the importance of dyspnea invisibility as a burden to COPD patients.

Out-of-pocket costs associated with chronic respiratory diseases in Korean adults.

Chronic respiratory diseases (CRDs) are a burden on both individuals and society. While previous literature has highlighted the clinical burden and total costs of care, it has not addressed patients' direct payments. This study aimed to estimate the incremental healthcare costs associated with patients with CRDs, specifically out-of-pocket (OOP) costs. We used survey data from the 2019 Korea Health Panel Survey to estimate the total OOP costs of CRDs by comparing the annual hospitalizations, outpatient visits, emergency room visits, and medications of patients with and without CRDs. Generalized linear regression models controlled for differences in other characteristics between groups. We identified 222 patients with CRDs, of whom 166 were aged 65 years and older. Compared with the non-CRD group, CRD patients spent more on OOP costs (238.3 USD on average). Incremental costs were driven by outpatient visits and medications, which are subject to a coinsurance of 30% or more and may include items not covered by public insurance. Moreover, CRD patients aged 50-64years incurred the highest incremental costs. The financial burden associated with CRDs is significant, and outpatient visits and medications constitute the largest components of OOP spending. Policymakers should introduce appropriate strategies to reduce CRD-associated burdens.

The accessibility and quality of health services for diabetes mellitus and chronic respiratory disease patients during Covid-19 in Northern Jordan: A mixed method study

Background The catastrophe caused by the Coronavirus disease has affected all services worldwide. A range of policies were introduced to slow the virus spread, which in turn, affected the accessibility and quality of healthcare services. This was a problematic and concerning for patients with chronic diseases, such as patients with diabetes mellitus (DM) and chronic respiratory diseases (CRD), due to their sustained need for ongoing health care. The aims of the study were: 1) assessing the level of both accessibility and quality of healthcare services during the Covid-19 pandemic from the DM and CRD patients’ perspectives, 2) assessing the association between the patients’ socio-demographics and their perspectives on health services accessibility and quality, and 3) exploring the perspectives of DM and CRD patients on barriers and facilitators of health services accessibility and quality during the era of COVID -19. Method Design. A sequential explanatory mixed-method was used in this study. In the quantitative part, a self -administered questionnaire was used to collect data from 300 patients with DM and/or CRD. In the qualitative part, focus group approach was used to collect data from 25 patients. Setting. Public, private and teaching hospitals were involved. Analysis. SPSS Version 25 was used to analyze the quantitative data. Thematic analysis was used to analyze the qualitative data. Results The quantitative findings indicated that almost 99% of the participating patients perceived barriers, ranging from low to high, to accessing health services during COVID-19. Additionally, more than half of the sample perceived low to moderate level of quality of health services. Four themes and nine subthemes related to barriers and facilitators were identified in the qualitative part of the study. Conclusion The study revealed that both quality and accessibility of healthcare services for DM and CRD patients were impacted during the era of COVID -19. The findings lay the ground for developing future health programs and establishing or revising policies with the goal of improving healthcare services quality and accessibility for the target population.

Chinese expert consensus on standardized inhaler device application in stable chronic airway diseases (2023)

Perceptions of the effectiveness of non-pharmacological management of respiratory disorders among CRD patients.

Chronic respiratory diseases (CRDs) are among the leading cause of mortality worldwide. While pharmacological approaches are commonly used to manage symptoms, non-pharmacological management of CRDs is considered crucial in preventing disease progression and improving patient self-efficacy. To describe the perceived effectiveness of non-pharmacological management of CRDs among CRD patients and determine whether the CRD patients perceptions of the effectiveness of non-pharmacological management are associated with their demographic characteristics. An analytic cross-sectional study design was utilized. The non-pharmacological management practices of CRD patients and their perception of the effectiveness of these therapeutic measures were assessed using a researcher-developed questionnaire. Data collection took place in primary healthcare centers in Al Ahsa, Saudi Arabia from October 2021 to March 2022. The proportion of CRD patients who perceived that non-pharmacological interventions were effective was computed. Binary logistic regression was performed to determine the association between the demographic characteristics of the respondents and their perception of the effectiveness of non-pharmacological management. Among the 390 respondents, 42% perceived that non-pharmacological measures were effective. Half of the respondents believed that smoking cessation, influenza vaccination, improving physical activity, and nutrition support helped alleviate CRD symptoms, while less than half of the respondents considered pulmonary rehabilitation, educational programs, and oxygen therapy effective measures to control symptoms. Women were found to be 3.24 times more likely to perceive non-pharmacological interventions as effective (P < .0000) compared to men. Those with university-level education were 66.6% less likely to consider non-pharmacological interventions to be effective (P < .0000) than those who completed preuniversity-level education. Age and marital status did not significantly influence perceptions of effectiveness. Differences in the perceptions of the effectiveness of various non-pharmacological measures to alleviate CRD symptoms existed among the CRD patients of Al Ahsa. The perception of effectiveness was significantly associated with the patient's gender and educational attainment.

The use of time-of-flight camera to assess respiratory rates and thoracoabdominal depths in patients with chronic respiratory disease.

Over the last 5 years, the analysis of respiratory patterns presents a growing usage in clinical and research purposes, but there is still currently a lack of easy-to-use and affordable devices to perform such kind of evaluation. The aim of this study is to validate a new specifically developed method, based on Kinect sensor, to assess respiratory patterns against spirometry under various conditions. One hundred and one participants took parts in one of the three validations studies. Twenty-five chronic respiratory disease patients (14 with chronic obstructive pulmonary disease (COPD) [65 ± 10 years old, FEV1 = 37 (15% predicted value), VC = 62 (20% predicted value)], and 11 with lung fibrosis (LF) [64 ± 14 years old, FEV1 = 55 (19% predicted value), VC = 62 (20% predicted value)]) and 76 healthy controls (HC) were recruited. The correlations between the signal of the Kinect (depth and respiratory rate) and the spirometer (tidal volume and respiratory rate) were computed in part 1. We then included 66 HC to test the ability of the system to detect modifications of respiratory patterns induced by various conditions known to modify respiratory pattern (cognitive load, inspiratory load and combination) in parts 2 and 3. There is a strong correlation between the depth recorded by the Kinect and the tidal volume recorded by the spirometer: r = 0.973 for COPD patients, r = 0.989 for LF patients and r = 0.984 for HC. The Kinect is able to detect changes in breathing patterns induced by different respiratory disturbance conditions, gender and oral task. Measurements performed with the Kinect sensors are highly correlated with the spirometer in HC and patients with COPD and LF. Kinect is also able to assess respiratory patterns under various loads and disturbances. This method is affordable, easy to use, fully automated and could be used in the current clinical context. Respiratory patterns are important to assess in daily clinics. However, there is currently no affordable and easy-to-use tool to evaluate these parameters in clinics. We validated a new system to assess respiratory patterns using the Kinect sensor in patients with chronic respiratory diseases.

Platelet-Rich Plasma Treatment for Chronic Respiratory Disease.

This study was conducted to test the hypothesis that platelet-rich plasma (PRP) therapy in chronic respiratory disease patients will cause lung regeneration, thereby slowing the progression of the disease. We performed a searchto obtain pertinentarticles on the following electronic databases: Google Scholar, PubMed, NCBI, Medscape, and clinicaltrials.gov. Keywords used during in search included "Platelet Rich Plasma" AND "Chronic Respiratory Disease" AND/OR "Chronic Obstructive Pulmonary Disease". A total of 15 articles were chosen for this paper, published from 2011 to 2021, and included case series, lab studies, animal studies, cohort studies, and clinical trials. All statistical data were considered significant if the p-value was less than 5%, or 0.05. Our findings confirmed that PRP therapy successfully caused anti-inflammatory effects and acceleration of tissue regeneration, resulting in improved lung function. This, in turn, slowed the progression of the disease and led to an improved quality of life. Not all chronic respiratory disease patients present in the same manner, but the connecting link is the damaged tissue of the lungs, causing issues with the functionality of the lungs. By adjunctively treating patients with PRP, the high concentration of platelets and their secreted growth factors can help induce an acceleration of healing and regeneration of pulmonary tissue. This, in turn, can slow the progression of the disease, which could lower the overall mortality rate in chronic respiratory disease patients. More studies should be conducted on this topic, specifically large, double-blinded, randomized human trials with controls, to further assess the efficacy and beneficial effects of PRP treatment on the lungs.

Immune responses to inactivated COVID-19 vaccine were decreased in Chinese patients with chronic respiratory diseases.

Purpose: The effectiveness of inactivated vaccines against acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), the causative agent of coronavirus disease 2019 (COVID-19), has become a global concern. Hence, the aim of this study was to evaluate vaccine safety and to assess immune responses in individuals with chronic respiratory disease (CRD) following a two-dose vaccination. Methods: The study cohort included 191 participants (112 adult CRD patients and 79 healthy controls [HCs]) at least 21 (range, 21-159) days after a second vaccination. Frequencies of memory B cells (MBCs) subsets and titers of SARS-CoV-2 neutralizing antibodies (NAbs) and anti-receptor binding domain (RBD) IgG antibodies (Abs) were analyzed. Results: As compared to the HCs, CRD patients had lower seropositivity rates and titers of both anti-RBD IgG Abs and NAbs, in addition to lower frequencies of RBD-specific MBCs (all, p < 0.05). At 3 months, CRD patients had lower seropositivity rates and titers of anti-RBD IgG Abs than the HCs (p < 0.05). For CoronaVac, the seropositivity rates of both Abs were lower in patients with old pulmonary tuberculosis than HCs. For BBIBP-CorV, the seropositivity rates of CoV-2 NAbs were lower in patients with chronic obstructive pulmonary disease than HCs (all, p < 0.05). Meanwhile, there was no significant difference in overall adverse events between the CRD patients and HCs. Univariate and multivariate analyses identified the time interval following a second vaccination as a risk factor for the production of anti-RBD IgG Abs and CoV-2 NAbs, while the CoronaVac had a positive effect on the titers of both Abs. Female was identified as a protective factor for CoV-2 NAb levels. Conclusion: Inactivated COVID-19 vaccines were safe and well tolerated by CRD patients but resulted in lower Ab responses and the frequencies of RBD-specific MBCs. Therefore, CRD patients should be prioritized for booster vaccinations.

Study the association between spirometry based functional grading and six minute walk distance in chronic respiratory disease patients at a rural tertiary care centre of India.

Six-min walk test (6MWT) is easy to use, the least expensive, and a quick measure of physical function and it reflects the capacity to perform our day-to-day activities hence quality of life can be assessed with 6MWT. This study was planned to assess the role of 6MWT in chronic respiratory disease patients and its association with spirometry-based functional grading at a rural tertiary care center of northern India. This was a hospital-based cross-sectional study done between December 2019 and July 2021. In this study, 110 patients were included as per inclusion and exclusion criteria. 6MWT and spirometry were conducted as per the American Thoracic Society/European Research Society recommendation using Spiropalm 6MWT and the association between 6MWT and spirometry was assessed. A total of 110 chronic respiratory disease patients were included in the study. There were 69 (63%) males while 41 (37%) were females. Among study participants, chronic obstructive pulmonary disease patients were the most common 48 (43.6%) patients, followed by asthma 28 (25.5%), posttuberculosis sequelae patients 22 (20%), interstitial lung disease 9 (8.2%), and bronchiectasis 3 (2.7%) patients were found. There was a significant positive correlation of 6-min walk distance (6MWD) and % predicted 6MWD with spirometric parameters, forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and there was a significant positive correlation of 6MWD with FEV1% (predicted) also. 6MWD and % predicted 6MWD negatively correlated with FEV1/FVC and association between 6MWD and FEV1/FVC was not statistically significant and between % predicted 6MWD and FEV1/FVC, it was found statistically significant. The 6MWD traveled by chronic respiratory disease patients was significantly lower than the predicted 6MWD and 6MWD correlated with spirometric variables well. Therefore, it can conclude that 6MWT is a useful alternative of spirometry in the management of chronic respiratory disease patients in resource-limited settings.
