Impact of COVID-19 Vaccine Rollout on Mental Health, Social Determinants of Health, and Attitudes Among Individuals With COPD.

Background: Social distancing early in the COVID-19 pandemic helped mitigate viral spread and protect vulnerable populations. Broad availability of vaccines allowed social re-integration, but effects on mental health, social determinants of health, and attitudes among individuals with chronic obstructive pulmonary disease (COPD), who are high risk for adverse outcomes following COVID-19 infection, are unknown.

Methods: Participants in the Losartan Effects on Emphysema Progression trial were recruited into an ancillary study from May to November 2020.

Telemedicine critical care availability and outcomes among mechanically ventilated patients.

Purpose: Telemedicine Critical Care (TCC) improves adherence to evidence based protocols associated with improved mortality among patients receiving invasive mechanical ventilation (IMV). We sought to evaluate the relationship between hospital availability of TCC and outcomes among patients receiving IMV.

Materials And Methods: We performed a cross-sectional study of 66,522 adults who received IMV for non-postoperative acute respiratory failure at 318 non-federal hospitals in New York, Massachusetts, Maryland, and Florida in 2018.

Do Biologic Therapies Decrease Mucus Plugging in Asthma?

Asthma researchers have long recognized that abnormal mucus production and clearance play a role in the pathophysiology of asthma. Mucus plugs are known to be common in patients with severe asthma, and mucus plug scores, for which higher scores indicate more severe plugging, are directly correlated with airflow obstruction and markers of eosinophilic airway inflammation (i.e.

The Role of ICS-Containing Rescue Therapy Versus SABA Alone in Asthma Management Today.

The Global Initiative for Asthma (GINA) recommends that short-acting β-agonist (SABA) monotherapy should no longer be prescribed, and that as-needed combination inhaled corticosteroids (ICS)-formoterol is the preferred reliever therapy in adults and adolescents with mild asthma. These recommendations are based on the risks of SABA monotherapy, the evidence that ICS-formoterol reliever therapy markedly decreases the occurrence of severe asthma exacerbations compared with SABA reliever therapy alone, and because ICS-formoterol reliever therapy has a favorable risk/benefit profile compared with maintenance ICS plus SABA reliever therapy. Data supporting the use of combination ICS-albuterol reliever therapy in mild asthma are more limited, but there are studies that inform its use in this population.

Use of Quantitative CT Imaging to Identify Bronchial Thermoplasty Responders.

Background: Bronchial thermoplasty (BT) is a treatment for patients with poorly controlled, severe asthma. However, predictors of treatment response to BT are defined poorly.

Research Question: Do baseline radiographic and clinical characteristics exist that predict response to BT?

Study Design And Methods: We conducted a longitudinal prospective cohort study of participants with severe asthma receiving BT across eight academic medical centers.

Beginning to Address an Implementation Gap in Asthma: Clinicians' Views of Prescribing Reliever Budesonide-Formoterol Inhalers and SMART in the United States.

Background: The Global Initiative for Asthma and National Asthma Education and Prevention Program recently made paradigm-shifting recommendations regarding inhaler management in asthma. The Global Initiative for Asthma now recommends that combination inhaled corticosteroid (ICS)-formoterol inhalers replace short-acting β-agonists as the preferred reliever therapy at all steps of asthma management. Although the most recent guidelines of the National Asthma Education and Prevention Program did not review reliever ICS-formoterol usage in mild asthma, they similarly recommended single maintenance and reliever therapy (SMART) at steps 3 and 4 of asthma management.

Symptom-driven inhaled corticosteroid/long-acting beta-agonist therapy for adult patients with asthma who are non-adherent to daily maintenance inhalers: a study protocol for a pragmatic randomized controlled trial.

Background: While inhaled corticosteroids (ICS) are considered the essential foundation of most asthma therapy, ICS inhaler nonadherence is a notoriously common problem and a significant cause of asthma-related morbidity. Partially acknowledging the problem of nonadherence, international organizations recently made paradigm-shifting recommendations that all patients with mild-to-moderate persistent asthma be considered for symptom-driven ICS-containing inhalers rather than relying on adherence to traditional maintenance ICS inhalers and symptom-driven short-acting beta-agonists (SABA). With this new approach, asthma patients are at least exposed to the important anti-inflammatory effects of ICS-containing inhalers when their symptom reliever inhaler is deployed due to acute symptoms.

Economic Evaluation of Ultrasound-guided Central Venous Catheter Confirmation vs Chest Radiography in Critically Ill Patients: A Labor Cost Model.

Introduction: Despite evidence suggesting that point-of-care ultrasound (POCUS) is faster and non-inferior for confirming position and excluding pneumothorax after central venous catheter (CVC) placement compared to traditional radiography, millions of chest radiographs (CXR) are performed annually for this purpose. Whether the use of POCUS results in cost savings compared to CXR is less clear but could represent a relative advantage in implementation efforts. Our objective in this study was to evaluate the labor cost difference for POCUS-guided vs CXR-guided CVC position confirmation practices.

Quantitative CT Characteristics of Cluster Phenotypes in the Severe Asthma Research Program Cohorts.

Background Clustering key clinical characteristics of participants in the Severe Asthma Research Program (SARP), a large, multicenter prospective observational study of patients with asthma and healthy controls, has led to the identification of novel asthma phenotypes. Purpose To determine whether quantitative CT (qCT) could help distinguish between clinical asthma phenotypes. Materials and Methods A retrospective cross-sectional analysis was conducted with the use of qCT images (maximal bronchodilation at total lung capacity [TLC], or inspiration, and functional residual capacity [FRC], or expiration) from the cluster phenotypes of SARP participants (cluster 1: minimal disease; cluster 2: mild, reversible; cluster 3: obese asthma; cluster 4: severe, reversible; cluster 5: severe, irreversible) enrolled between September 2001 and December 2015.

Asthma in patients with suspected and diagnosed coronavirus disease 2019.

Background: Patients with asthma are comparatively susceptible to respiratory viral infections and more likely to develop severe symptoms than people without asthma. During the coronavirus disease 2019 (COVID-19) pandemic, it is necessary to adequately evaluate the characteristics and outcomes of the population with asthma in the population tested for and diagnosed as having COVID-19.

Objective: To perform a study to assess the impact of asthma on COVID-19 diagnosis, presenting symptoms, disease severity, and cytokine profiles.

Quantitative CT metrics are associated with longitudinal lung function decline and future asthma exacerbations: Results from SARP-3.

Background: Currently, there is limited knowledge regarding which imaging assessments of asthma are associated with accelerated longitudinal decline in lung function.

Objectives: We aimed to assess whether quantitative computed tomography (qCT) metrics are associated with longitudinal decline in lung function and morbidity in asthma.

Methods: We analyzed 205 qCT scans of adult patients with asthma and calculated baseline markers of airway remodeling, lung density, and pointwise regional change in lung volume (Jacobian measures) for each participant.

The emerging role of quantitative imaging in asthma.

Quantitative imaging of the lung has proved to be a valuable tool that has improved our understanding of asthma. CT, MRI, and positron emission tomography have all been utilized in asthma with each modality having its own distinct advantages and disadvantages. Research has now demonstrated that quantitative imaging plays a valuable role in characterizing asthma phenotypes and endotypes, as well as potentially predicting future asthma morbidity.

Biologics for Severe Asthma: Treatment-Specific Effects Are Important in Choosing a Specific Agent.

Patients with uncontrolled severe persistent asthma have greater morbidity, greater use of health care resources, and more impairment in health-related quality of life when compared with their peers with well-controlled disease. Fortunately, since the introduction of biological therapeutics, patients with severe eosinophilic asthma now have beneficial treatment options that they did not have just a few years ago. In addition to anti-IgE therapy for allergic asthma, 3 new biological therapeutics targeting IL-5 and 1 targeting IL-4 and IL-13 signaling have recently been approved by the Food and Drug Administration for the treatment of severe eosinophilic asthma, and approval of more biological therapeutics is on the horizon.

Role of Biologics in Asthma.

Patients with severe uncontrolled asthma have disproportionally high morbidity and healthcare utilization as compared with their peers with well-controlled disease. Although treatment options for these patients were previously limited, with unacceptable side effects, the emergence of biologic therapies for the treatment of asthma has provided promising targeted therapy for these patients. Biologic therapies target specific inflammatory pathways involved in the pathogenesis of asthma, particularly in patients with an endotype driven by type 2 (T2) inflammation.

Urinary cysteinyl leukotriene E(4) is associated with increased risk for pain and acute chest syndrome in adults with sickle cell disease.

Leukotriene E(4) (LTE(4)) levels are associated with rate of pain episodes in children with sickle cell disease (SCD). Because complications of SCD manifest differently in adults than children, we examined a cohort of adults with SCD to determine the relationship between baseline LTE(4) and SCD-related morbidity. Baseline LTE(4) levels were associated with increased rates of pain and acute chest syndrome (ACS) episodes, when those with LTE(4) values in the highest tertile were compared with those in the lowest tertile (pain: risk ratio 7.
