Background: Metered-dose inhalers with valved holding chambers (MDI-VHCs) have been shown to be equivalent to small-volume nebulizers (SVNs) for the delivery of bronchodilators in children. At Seattle Children's Hospital and Regional Medical Center we sought to implement the conversion from SVN to MDI-delivered albuterol in nonintubated patients receiving intermittent treatments.
Methods: There were 4 distinct interventions used to plan and implement this conversion program: (1) literature review, (2) product selection, (3) policy and operational changes, and (4) staff training. Bronchodilator administration guidelines and clinical pathways for asthma and bronchiolitis were revised to recommend MDI-VHC use in lieu of SVNs. Computerized physician order sets were amended to indicate MDI-VHC as the preferred method of delivering inhaled albuterol in children with asthma and bronchiolitis. Data from administrative case mix files and computerized medication delivery systems were used to assess the impact of our program.
Results: MDI-VHC utilization increased from 25% to 77% among all non-intensive-care patients receiving albuterol, and from 10% to 79% among patients with asthma (p < 0.001). Duration of stay among patients with asthma was unchanged after conversion to MDI-VHC (p = 0.53).
Conclusions: Our program was very successful at promoting the use of MDI-VHC for the administration of albuterol in our pediatric hospital. Duration of stay among patients with asthma did not change during or since the implementation of this program.

Background: In patients with asthma, bronchoconstriction and airway inflammation both contribute to airway narrowing and airflow limitations, which lead to symptoms and exacerbations. Short-acting beta 2-agonist (SABA)-only rescue therapy addresses only bronchoconstriction and is associated with increased morbidity and mortality. Current asthma management guidelines recommend concomitant treatment of symptoms and inflammation with a fast-acting bronchodilator and inhaled corticosteroid (ICS) as rescue therapy for patients 12 years of age.

Background: Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infection, hospitalisation and death in adults.
Methods: Based on evidence regarding the impact of RSV on adult populations at risk for severe infection and the efficacy and safety of RSV vaccines, the Portuguese Society of Pulmonology, the Portuguese Association of General and Family Medicine, the Portuguese Society of Cardiology, the Portuguese Society of Infectious Diseases and Clinical Microbiology, the Portuguese Society of Endocrinology, Diabetes and Metabolism, and the Portuguese Society of Internal Medicine endorses this position paper with recommendations to prevent RSV-associated disease and its complications in adults through vaccination.
Conclusion: The RSV vaccine is recommended for people aged ≥50 years with risk factors (chronic obstructive pulmonary disease, asthma, heart failure, coronary artery disease, diabetes, chronic kidney disease, chronic liver disease, immunocompromise, frailty, dementia, and residence in a nursing home) and all persons aged ≥60 years.
Retrospective Cohort Study of Elderly Users of Single- or Multiple-Inhaler Triple Therapy for the Treatment of Asthma in the USA.

US Medical Affairs, GSK, ATC Fowler Building, 410 Blackwell Street, Durham, NC, 27701, USA.
Introduction: Escalation to single- or multiple-inhaler triple therapy (SITT; MITT) is a recommended option for patients with asthma who remain uncontrolled by medium-dose inhaled corticosteroid/long-acting β-agonist; however, characterization of elderly users of triple therapy is limited. This real-world cohort study describes demographics and clinical characteristics of elderly patients with asthma with and without comorbid chronic obstructive pulmonary disease (COPD) who are new users of triple therapy, and asthma treatment patterns preceding triple therapy initiation.
Methods: This retrospective cohort study used administrative claims data from the Optum Clinformatics Data Mart database.
New approaches in childhood IgE-mediated food allergy treatment.
Curr Opin Allergy Clin Immunol
January 2025
Translational Research in Pediatric Specialities, Division of Allergy, Bambino Gesù Children's Hospital, IRCCS, Rome, Italy.
Purpose Of Review: This review aims to provide an overview of the current and future treatment options for children with food allergies (FAs), highlighting the latest research findings and the potential impact of these new approaches on improving patients' and caregivers' quality of life.
Recent Findings: In the last decade, many promising approaches have emerged as an alternative to the standard avoidance of the culprit food with the risk of severe accidental reactions. Desensitization through oral immunotherapy has been introduced in clinical settings as a therapeutic approach, and more recently also omalizumab.
Cumulative Dispensing of Oral Corticosteroids Over 12 Months in People with COPD.
Int J Chron Obstruct Pulmon Dis

School of Translational Medicine, Monash University, Melbourne, VIC, Australia.
Purpose: Oral corticosteroids (OCS) are recommended for the treatment of exacerbations in people with COPD; however, high cumulative lifetime doses (≥1000mg prednisolone-equivalent) are associated with adverse health effects. This issue is well defined in asthma but is less well understood in COPD. The aim of this study was to examine cumulative OCS dispensed to people with COPD over 12 months.
