pi Evidence-based management of symptoms in serious respiratory illness: what is in our toolbox? By err.ersjournals.com Published On :: 2024-10-30T01:30:15-07:00 Extract Living with a respiratory illness requires patients to manage a wide range of symptoms, many of which will worsen as a disease progresses. Breathlessness is a hallmark feature of respiratory conditions, occurring in almost all individuals with COPD and interstitial lung disease (ILD) [1, 2]. Cough is present in 78% of people with ILD and is frequently distressing, with physical, social and emotional impacts [1, 3]. Full Article
pi Antibody-mediated protection against respiratory syncytial virus in children By err.ersjournals.com Published On :: 2024-10-09T00:15:15-07:00 Respiratory syncytial virus (RSV) is a major global pathogen, causing lower respiratory tract disease in at-risk populations including young children. Antibodies form a crucial layer of protection from RSV disease, particularly in immunologically naïve infants. Such antibodies are derived from the mother via transplacental transfer and breast milk, but may be particularly low in high-risk infants such as those born preterm. Maternally derived antibodies can now be supplemented by the administration of anti-RSV monoclonal antibodies, while a rising wave of maternal and paediatric vaccine strategies are approaching. The implementation of these prophylactics may profoundly decrease the healthcare burden of RSV. In this article, we review the role of antibody-mediated immunity in protecting children from RSV. We focus on maternally derived antibodies as the main source of protection against RSV and study factors that influence the scale of this transfer. The role of passive and active prophylactic approaches in protecting infants against RSV are discussed and knowledge gaps in our understanding of antibody-mediated protection against RSV are identified.

pi Epidemiology of severe asthma in children: a systematic review and meta-analysis By err.ersjournals.com Published On :: 2024-10-09T00:15:15-07:00 Background Severe asthma significantly impacts a minority of children with asthma, leading to frequent symptoms, hospitalisations and potential long-term health consequences. However, accurate global data on severe asthma epidemiology is lacking. This study aims to address this gap, providing data on severe asthma epidemiology, regional differences and associated comorbidities. Methods We conducted a rigorous systematic review and meta-analysis following a registered protocol (PROSPERO CRD42023472845). We searched PubMed, Scopus and Web of Science for cohort or cross-sectional studies published since 2003, evaluating severe asthma incidence and prevalence in children. Study quality and risk of bias were assessed using STROBE guidelines. Results Nine studies investigating European children with asthma (aged 5–18 years) were included in the meta-analysis. No significant publication bias was found. The overall severe asthma prevalence in children with asthma was 3% (95% CI 1–6; I2=99.9%; p<0.001), with no significant difference between males and females. Prevalence estimates varied significantly depending on the diagnostic criteria used (Global Initiative for Asthma: 6%; European Respiratory Society/American Thoracic Society: 1%; other: 3%). Because none of the examined studies were prospectively designed, incidence rates could not be determined. Conclusions This systematic review and meta-analysis provide the first robust assessment of severe asthma prevalence among European children. Our findings underscore the need for comprehensive research to address knowledge gaps in severe asthma, including determining incidence rates, standardising definitions, investigating regional differences and evaluating comorbidities and treatment strategies.

pi Epidemiology of bronchiectasis By err.ersjournals.com Published On :: 2024-10-09T00:15:15-07:00 Bronchiectasis is a chronic respiratory disease characterised by permanent enlargement of the airways associated with cough, sputum production and a history of pulmonary exacerbations. In the past few years, incidence and prevalence of bronchiectasis have increased worldwide, possibly due to advances in imaging techniques and disease awareness, leading to increased socioeconomic burden and healthcare costs. Consistently, a mortality increase in bronchiectasis patient cohorts has been demonstrated in certain areas of the globe, with mortality rates of 16–24.8% over 4–5 years of follow-up. However, heterogeneity in epidemiological data is consistent, as reported prevalence in the general population ranges from 52.3 to more than 1000 per 100 000. Methodological flaws in the designs of available studies are likely to underestimate the proportion of people suffering from this condition worldwide and comparisons between different areas of the globe might be unreliable due to different assessment methods or local implementation of the same method in different contexts. Differences in disease severity associated with diverse geographical distribution of aetiologies, comorbidities and microbiology might explain an additional quota of heterogeneity. Finally, limited access to care in certain geographical areas is associated with both underestimation of the disease and increased severity and mortality. The aim of this review is to provide a snapshot of available real-world epidemiological data describing incidence and prevalence of bronchiectasis in the general population. Furthermore, data on mortality, healthcare burden and high-risk populations are provided. Finally, an analysis of the geographical distribution of determinants contributing to differences in bronchiectasis epidemiology is offered. Full Article
pi Multicomponent services for symptoms in serious respiratory illness: a systematic review and meta-analysis By err.ersjournals.com Published On :: 2024-10-30T01:30:15-07:00 Background People living with serious respiratory illness experience a high burden of symptoms. This review aimed to determine whether multicomponent services reduce symptoms in people with serious illness related to respiratory disease. Methods Electronic databases were searched to identify randomised controlled trials (RCTs) evaluating multicomponent services that enrolled patients due to symptoms, rather than underlying disease, and provided at least one nonpharmacological intervention. The primary outcome was chronic breathlessness and secondary outcomes were health-related quality of life (HRQoL), cough, fatigue and adverse events. At least two authors independently screened studies, assessed risk of bias and extracted data. Results Five RCTs, involving 439 patients, were included. In comparison to usual care, multicomponent services improved breathlessness mastery (Chronic Respiratory Questionnaire (CRQ) mastery scale, mean difference (MD) 0.43 points, 95% CI 0.20–0.67, three RCTs, 327 participants) and HRQoL (CRQ total score, MD 0.24 points, 95% CI 0.04–0.40, two RCTs, 237 participants). Fatigue did not improve with multicomponent services and no studies evaluated cough. No serious adverse events were reported. The one study evaluating mortality found increased survival in those accessing a multicomponent service. The certainty of evidence was very low, mainly due to detection and reporting bias. Conclusion Multicomponent services improve breathlessness mastery and HRQoL, with minimal risk. These findings support the use of multicomponent symptom-directed services for people living with serious respiratory illness. Full Article
pi The effect of graded exercise therapy on fatigue in people with serious respiratory illness: a systematic review By err.ersjournals.com Published On :: 2024-10-09T00:15:15-07:00 Background In adults with serious respiratory illness, fatigue is prevalent and under-recognised, with few treatment options. The aim of this review was to assess the impact of graded exercise therapy (GET) on fatigue in adults with serious respiratory illness. Methods Electronic databases were searched to identify randomised controlled trials (RCTs) testing GET (involving incremental increases in exercise from an established baseline) in adults with serious respiratory illness. The primary outcome was fatigue and secondary outcomes were health-related quality of life (HRQoL) and adverse events. Two authors independently screened for inclusion, evaluated risk of bias and extracted data. Results 76 RCTs were included with 3309 participants, most with a diagnosis of COPD or asthma. Reductions in fatigue measured by the Chronic Respiratory Disease Questionnaire fatigue domain score were demonstrated following GET consisting of aerobic with/without resistance training (mean difference (MD) 0.53 points, 95% CI 0.41–0.65, 11 RCTs, 624 participants) and GET using resistance training alone (MD 0.58 points, 95% CI 0.21–0.96, two RCTs, 82 participants) compared with usual care. Although the mean effect exceeded the minimal important difference, the lower end of the confidence intervals did not always exceed this threshold so the clinical significance could not be confirmed. GET consistently improved HRQoL in people with a range of chronic respiratory diseases on multiple HRQoL measures. No serious adverse events related to GET were reported. Conclusion GET may improve fatigue alongside consistent improvements in HRQoL in people with serious respiratory illness. These findings support the use of GET in the care of people with serious respiratory illness. Full Article
pi Breathing techniques to reduce symptoms in people with serious respiratory illness: a systematic review By err.ersjournals.com Published On :: 2024-10-30T01:30:15-07:00 Background In adults with serious respiratory illness, breathlessness is prevalent and associated with reduced health-related quality of life. The aim of this review was to assess the impact of breathing techniques on breathlessness in adults with serious respiratory illness. Methods Electronic databases were searched to identify randomised controlled trials testing breathing techniques (techniques that aim to alter the respiratory pattern, excluding respiratory muscle training) in people with serious respiratory illness. The primary outcome was breathlessness and secondary outcomes were health-related quality of life and adverse events. Two authors independently screened for inclusion, evaluated risk of bias and extracted data. Results 73 randomised controlled trials were included with 5479 participants, most with COPD or asthma. Breathing exercises (pursed lip and/or diaphragmatic breathing) reduced breathlessness measured by the modified Medical Research Council scale compared to usual care (mean difference (MD) –0.40 points, 95% CI –0.70– –0.11, eight studies, n=323), although the effect did not exceed the minimal important difference. Yoga breathing also improved modified Medical Research Council score compared to usual care (MD –1.05 points, 95% CI –2.45–0.35, three studies, n=175). Breathing techniques consistently improved health-related quality of life in people with COPD and asthma on multiple health-related quality of life measures in comparison to usual care, with effects that generally exceeded the minimal important difference. No adverse events related to breathing techniques were reported. Conclusion Breathing techniques may improve breathlessness, and consistently improve health-related quality of life, in people with serious respiratory illness. These findings support the use of breathing exercises in the care of people with serious respiratory illness. Full Article
pi Opioids for the palliation of symptoms in people with serious respiratory illness: a systematic review and meta-analysis By err.ersjournals.com Published On :: 2024-10-09T00:15:15-07:00 Background People living with serious respiratory illness experience a high burden of distressing symptoms. Although opioids are prescribed for symptom management, they generate adverse events, and their benefits are unclear. Methods We examined the efficacy and safety of opioids for symptom management in people with serious respiratory illness. Embase, MEDLINE and the Cochrane Central Register of Controlled Trials were searched up to 11 July 2022. Reports of randomised controlled trials administering opioids to treat symptoms in people with serious respiratory illness were included. Key exclusion criteria included <80% of participants having a nonmalignant lung disease. Data were extracted regarding study characteristics, outcomes of breathlessness, cough, health-related quality of life (HRQoL) and adverse events. Treatment effects were pooled using a generic inverse variance model with random effects. Risk of bias was assessed using the Cochrane Risk of Bias tool version 1. Results Out of 17 included trials, six were laboratory-based exercise trials (n=70), 10 were home studies measuring breathlessness in daily life (n=788) and one (n=18) was conducted in both settings. Overall certainty of evidence was "very low" to "low". Opioids reduced breathlessness intensity during laboratory exercise testing (standardised mean difference (SMD) –0.37, 95% CI –0.67– –0.07), but not breathlessness measured in daily life (SMD –0.10, 95% CI –0.64–0.44). No effects on HRQoL (SMD –0.42, 95% CI –0.98–0.13) or cough (SMD –1.42, 95% CI –3.99–1.16) were detected. In at-home studies, opioids led to increased frequency of nausea/vomiting (OR 3.32, 95% CI 1.70–6.51), constipation (OR 3.08, 95% CI 1.69–5.61) and drowsiness (OR 1.37, 95% CI 1.01–1.86), with serious adverse events including hospitalisation and death identified. Conclusions Opioids improved exertional breathlessness in laboratory exercise studies, but did not improve breathlessness, cough or HRQoL measured in daily life at home. There were significant adverse events, which may outweigh any benefits. Full Article
pi Seamless, rapid, and accurate analyses of outbreak genomic data using split k-mer analysis [METHODS] By genome.cshlp.org Published On :: 2024-10-29T06:46:08-07:00 Sequence variation observed in populations of pathogens can be used for important public health and evolutionary genomic analyses, especially outbreak analysis and transmission reconstruction. Identifying this variation is typically achieved by aligning sequence reads to a reference genome, but this approach is susceptible to reference biases and requires careful filtering of called genotypes. There is a need for tools that can process this growing volume of bacterial genome data, providing rapid results, but that remain simple so they can be used without highly trained bioinformaticians, expensive data analysis, and long-term storage and processing of large files. Here we describe split k-mer analysis (SKA2), a method that supports both reference-free and reference-based mapping to quickly and accurately genotype populations of bacteria using sequencing reads or genome assemblies. SKA2 is highly accurate for closely related samples, and in outbreak simulations, we show superior variant recall compared with reference-based methods, with no false positives. SKA2 can also accurately map variants to a reference and be used with recombination detection methods to rapidly reconstruct vertical evolutionary history. SKA2 is many times faster than comparable methods and can be used to add new genomes to an existing call set, allowing sequential use without the need to reanalyze entire collections. With an inherent absence of reference bias, high accuracy, and a robust implementation, SKA2 has the potential to become the tool of choice for genotyping bacteria. SKA2 is implemented in Rust and is freely available as open-source software. Full Article
pi Rapid SARS-CoV-2 surveillance using clinical, pooled, or wastewater sequence as a sensor for population change [METHODS] By genome.cshlp.org Published On :: 2024-10-29T06:46:08-07:00 The COVID-19 pandemic has highlighted the critical role of genomic surveillance for guiding policy and control. Timeliness is key, but sequence alignment and phylogeny slow most surveillance techniques. Millions of SARS-CoV-2 genomes have been assembled. Phylogenetic methods are ill equipped to handle this sheer scale. We introduce a pangenomic measure that examines the information diversity of a k-mer library drawn from a country's complete set of clinical, pooled, or wastewater sequence. Quantifying diversity is central to ecology. Hill numbers, or the effective number of species in a sample, provide a simple metric for comparing species diversity across environments. The more diverse the sample, the higher the Hill number. We adopt this ecological approach and consider each k-mer an individual and each genome a transect in the pangenome of the species. Structured in this way, Hill numbers summarize the temporal trajectory of pandemic variants, collapsing each day's assemblies into genome equivalents. For pooled or wastewater sequence, we instead compare days using survey sequence divorced from individual infections. Across data from the UK, USA, and South Africa, we trace the ascendance of new variants of concern as they emerge in local populations well before these variants are named and added to phylogenetic databases. Using data from San Diego wastewater, we monitor these same population changes from raw, unassembled sequence. This history of emerging variants senses all available data as it is sequenced, intimating variant sweeps to dominance or declines to extinction at the leading edge of the COVID-19 pandemic.

pi Evidence for compensatory evolution within pleiotropic regulatory elements [RESEARCH] By genome.cshlp.org Published On :: 2024-10-29T06:46:07-07:00 Pleiotropy, measured as expression breadth across tissues, is one of the best predictors for protein sequence and expression conservation. In this study, we investigated its effect on the evolution of cis-regulatory elements (CREs). To this end, we carefully reanalyzed the Epigenomics Roadmap data for nine fetal tissues, assigning a measure of pleiotropic degree to nearly half a million CREs. To assess the functional conservation of CREs, we generated ATAC-seq and RNA-seq data from humans and macaques. We found that more pleiotropic CREs exhibit greater conservation in accessibility, and the mRNA expression levels of the associated genes are more conserved. This trend of higher conservation for higher degrees of pleiotropy persists when analyzing the transcription factor binding repertoire. In contrast, simple DNA sequence conservation of orthologous sites between species tends to be even lower for pleiotropic CREs than for species-specific CREs. Combining various lines of evidence, we propose that the lack of sequence conservation in functionally conserved pleiotropic CREs is owing to within-element compensatory evolution. In summary, our findings suggest that pleiotropy is also a good predictor for the functional conservation of CREs, even though this is not reflected in the sequence conservation of pleiotropic CREs.

pi Targeted and complete genomic sequencing of the major histocompatibility complex in haplotypic form of individual heterozygous samples [RESEARCH] By genome.cshlp.org Published On :: 2024-10-29T06:46:07-07:00 The human major histocompatibility complex (MHC) is a ~4 Mb genomic segment on Chromosome 6 that plays a pivotal role in the immune response. Despite its importance in various traits and diseases, its complex nature makes it challenging to accurately characterize on a routine basis. We present a novel approach allowing targeted sequencing and de novo haplotypic assembly of the MHC region in heterozygous samples, using long-read sequencing technologies. Our approach is validated using two reference samples, two family trios, and an African-American sample. We achieved excellent coverage (96.6%–99.9% with at least 30x depth) and high accuracy (99.89%–99.99%) for the different haplotypes. This methodology offers a reliable and cost-effective method for sequencing and fully characterizing the MHC without the need for whole-genome sequencing, facilitating broader studies on this important genomic segment and having significant implications in immunology, genetics, and medicine.

pi Assessing Patient Readiness for Hospital Discharge, Discharge Communication, and Transitional Care Management By www.jabfm.org Published On :: 2024-10-25T09:26:14-07:00 Background: Discharge communication between hospitalists and primary care clinicians is essential to improve care coordination, minimize adverse events, and decrease unplanned health services use. Health-related social needs are key drivers of health, and hospitalists and primary care clinicians value communicating social needs at discharge. Objective: To 1) characterize the current state of discharge communications between an academic medical center hospital and primary care clinicians at associated clinics; 2) seek feedback about the potential usefulness of discharge readiness information to primary care clinicians. Design: Exploratory, convergent mixed methods. Participants: Primary care clinicians from Family Medicine and General Internal Medicine of an academic medical center in the US Intermountain West. Approach: Literature-informed REDCap survey. Semistructured interview guide developed with key informants, grounded in current literature. Survey data were descriptively summarized; interview data were deductively and inductively coded, organized by topics. Results: Two key topics emerged: 1) discharge communication, with interrelated topics of transitional care management and follow-up appointment challenges, and recommendations for improving discharge communication; and 2) usefulness of the discharge readiness information, included interrelated topics related to lack of shared understanding about roles and responsibilities across settings and ethical concerns related to identifying problems that may not have solutions. Conclusions: While reiterating perennial discharge communication and transitional care management challenges, this study reveals new evidence about how these issues are interrelated with assessing and responding to patients’ lack of readiness for discharge and unmet social needs during care transitions. Primary care clinicians had mixed views on the usefulness of discharge readiness information. We offer recommendations for improving discharge communication and transitional care management (TCM) processes, which may be applicable in other care settings. Full Article
pi Using Primary Health Care Electronic Medical Records to Predict Hospitalizations, Emergency Department Visits, and Mortality: A Systematic Review By www.jabfm.org Published On :: 2024-10-25T09:26:14-07:00 Introduction: High-quality primary care can reduce avoidable emergency department visits and emergency hospitalizations. The availability of electronic medical record (EMR) data and capacities for data storage and processing have created opportunities for predictive analytics. This systematic review examines studies which predict emergency department visits, hospitalizations, and mortality using EMR data from primary care. Methods: Six databases (Ovid MEDLINE, PubMed, Embase, EBM Reviews (Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register, Health Technology Assessment, NHS Economic Evaluation Database), Scopus, CINAHL) were searched to identify primary peer-reviewed studies in English from inception to February 5, 2020. The search was initially conducted on January 18, 2019, and updated on February 5, 2020. Results: A total of 9456 citations were double-reviewed, and 31 studies met the inclusion criteria. The predictive ability measured by C-statistics (ROC) of the best performing models from each study ranged from 0.57 to 0.95. Less than half of the included studies used artificial intelligence methods and only 7 (23%) were externally validated. Age, medical diagnoses, sex, medication use, and prior health service use were the most common predictor variables. Few studies discussed or examined the clinical utility of models. Conclusions: This review helps address critical gaps in the literature regarding the potential of primary care EMR data. Despite further work required to address bias and improve the quality and reporting of prediction models, the use of primary care EMR data for predictive analytics holds promise. Full Article

pi Home Respiratory Strategies in Patients With COPD With Chronic Hypercapnic Respiratory Failure By rc.rcjournal.com Published On :: 2024-10-25T05:44:13-07:00 BACKGROUND:Home noninvasive ventilation (NIV) may improve chronic hypercarbia in COPD and patient-important outcomes. The efficacy of home high-flow nasal cannula (HFNC) as an alternative is unclear.METHODS:We searched MEDLINE, Embase, Cochrane CENTRAL, Scopus, and ClinicalTrials.gov for randomized trials of subjects from inception to March 31, 2023, and updated the search on July 14, 2023. We performed a frequentist network meta-analysis and assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We analyzed randomized controlled trials (RCTs) comparing NIV, HFNC, or standard care in adult subjects with COPD with chronic hypercapnic respiratory failure. Outcomes included mortality, COPD exacerbations, hospitalizations, and quality of life (St George Respiratory Questionnaire [SGRQ]).RESULTS:We analyzed 24 RCTs (1,850 subjects). We found that NIV may reduce the risk of death compared to standard care (relative risk 0.82 [95% CI 0.66–1.00]) and probably reduces exacerbations (relative risk 0.71 [95% CI 0.58–0.87]). HFNC probably reduces exacerbations compared to standard care (relative risk 0.77 [0.68–0.88]), but its effect on mortality is uncertain (relative risk 1.20 [95% CI 0.63–2.28]). HFNC probably improves SGRQ scores (mean difference −7.01 [95% CI −12.27 to −1.77]) and may reduce hospitalizations (relative risk 0.87 [0.69–1.09]) compared to standard care. No significant difference was observed between HFNC and NIV in reducing exacerbations.CONCLUSIONS:Both NIV and HFNC reduce exacerbation risks in subjects with COPD compared to standard care. HFNC may offer advantages in improving quality of life. Full Article
