Comparative Study
Use of selective serotonin reuptake inhibitors and outcomes in pulmonary arterial hypertension.
Selective serotonin reuptake inhibitors (SSRIs) have been suggested to offer therapeutic benefit in patients with pulmonary arterial hypertension (PAH). We conducted two analyses to explore the association between SSRI use and PAH outcomes using the Registry to Evaluate Early and Long-term PAH Disease Management (REVEAL Registry). ⋯ In a large population of patients with PAH, incident SSRI use was associated with increased mortality and a greater risk of clinical worsening, although we could not adjust for all potential confounders.

Randomized Controlled Trial
A prospective study of respiratory viral infection in pregnant women with and without asthma.
Respiratory viral infections are common in pregnancy, but their health impact, especially in asthma, is unknown. The objective of this study was to assess the frequency, severity, and consequences of respiratory viral infection during pregnancy in women with and without asthma. ⋯ Pregnant women with asthma have more common colds during pregnancy than pregnant women without asthma. Colds during pregnancy were associated with adverse maternal and pregnancy outcomes. Prevention of viral infection in pregnancy may improve the health of mothers with asthma.

Positive airway pressure (PAP) therapy is considered the most efficacious treatment of obstructive sleep apnea (OSA), especially moderate to severe OSA, and remains the most commonly prescribed. Yet suboptimal adherence presents a challenge to sleep-medicine clinicians. The purpose of the current review is to highlight the efficacy of published interventions to improve PAP adherence and to suggest a patient-centered clinical approach to enhancing PAP usage.

We aimed to evaluate the availability and practice of spirometry, training of technicians, and spirometer features and maintenance in Spain in both primary care (PC) and secondary care (SC) centers. ⋯ This survey maps for the first time, to our knowledge, the current situation of spirometry in Spain, identifying bottlenecks and suggesting future directions applicable in both PC and SC centers and elsewhere.

Although traditionally thought to be sterile, accumulating evidence now supports the concept that our airways harbor a microbiome. Thus far, studies have focused upon characterizing the bacterial constituents of the airway microbiome in both healthy and diseased lungs, but what perhaps provides the greatest impetus for the exploration of the airway microbiome is that different bacterial phyla appear to dominate diseased as compared with healthy lungs. As yet, there is very limited evidence supporting a functional role for the airway microbiome, but continued research in this direction is likely to provide such evidence, particularly considering the progress that has been made in understanding host-microbe mutualism in the intestinal tract. In this review, we highlight the major advances that have been made discovering and describing the airway microbiome, discuss the experimental evidence that supports a functional role for the microbiome in health and disease, and propose how this emerging field is going to impact clinical practice.
