People with cystic fibrosis (pwCF) have experienced increased survival and wellbeing in recent decades, such that more than half of those living with CF are adults. Consequently, sexual and reproductive health is increasingly important for pwCF, because many are considering parenthood. Most men and some women with CF (wwCF) will have reduced fertility, which in both sexes is multifactorial. ⋯ Most drugs used to treat CF are considered safe in pregnancy and lactation, but exceptions need to be acknowledged, including the limited data regarding safety of CF transmembrane conductance regulator (CFTR) modulators during conception, pregnancy, and lactation. Because most pwCF are eligible for highly effective CFTR modulators, fertility, contraception, and pregnancy in people with CF is changing. Prospective studies regarding these issues in people treated with CFTR modulators are paramount to provide evidence-based guidance for management in the current era of CF care.

Multicenter Study
Bilevel non-invasive ventilation during exercise reduces dynamic hyperinflation and improves cycle endurance time in severe to very severe COPD.
During exercise, dynamic hyperinflation (DH), measured by a reduction in inspiratory capacity (IC), increases exertional dyspnea and reduces functional capacity in many patients with severe COPD. Although noninvasive ventilation (NIV) during exercise can improve exercise duration, the effect on DH is unclear. ⋯ In people with COPD and DH during exercise, NIV during exercise reduced DH and increased cycle endurance time. An S-EPAP of 5 cm H2O was adequate to obtain these benefits.

A 56-year-old man has difficult-to-control asthma and a history of four exacerbations in the prior 12 months despite high-dose inhaled corticosteroids (ICS) and additional controller therapies. Is he suitable for more advanced therapeutic options? To address this query, we herein review the clinical assessment of a patient with suspected severe asthma and discuss factors contributing to poor asthma control and how biomarkers assist in disease investigation and stratification. The key components of our multidisciplinary approach are to confirm an asthma diagnosis and adherence to treatment, to assess any contributing comorbidities or confounding factors, and to stratify what type of asthma the patient has. ⋯ Critically, steroids can cause harm, and their use should be guided by objective evidence of inflammation rather than symptoms alone. To conclude, after assessment of treatment adherence and exclusion of relevant comorbidities, the patient was found to have severe asthma with ICS-resistant type 2 airway inflammation. We will consider additional treatment options at our next appointment in part 2/2 of this How I Do It series.

Targeted therapies for advanced non-small cell lung cancer (NSCLC) with oncogenic drivers have caused a paradigm shift in care. Biomarker testing is needed to assess eligibility for these therapies. Pulmonologists often perform bronchoscopy, providing tissue for both pathologic diagnosis and biomarker analysis. We performed this survey to define the existing knowledge and practices regarding the pulmonologists' role in biomarker testing for advanced NSCLC. ⋯ Substantial differences among pulmonologists' evaluation of advanced NSCLC, variation in knowledge of available biomarkers and the importance of targeted therapies, and differences in institutional coordination likely lead to underutilization of biomarker testing. Interventional training appears to drive improved knowledge and practice for biomarker testing more than practice setting. Improvements are needed in tissue acquisition and interdisciplinary coordination to ensure universal and comprehensive testing for eligible patients.

Neonatal lung ultrasound and surfactant administration: a pragmatic, multicenter study.
Previous research shows that a lung ultrasound score (LUS) can anticipate CPAP failure in neonatal respiratory distress syndrome. ⋯ LUS is a reliable criterion to administer the first surfactant dose regardless of GA. Its association with oxygen saturation to Fio2 ratio significantly improves the prediction power for surfactant need.
