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.

Optimal Tricuspid Regurgitation Velocity to Screen for Pulmonary Hypertension in Tertiary Referral Centers.
A mean pulmonary artery pressure >20 mm Hg now defines pulmonary hypertension. We hypothesize that echocardiographic thresholds must be adjusted. ⋯ Our data support a lower tricuspid regurgitation velocity of approximately 2.7 m/s for screening pulmonary hypertension, with a high sensitivity in tertiary referral centers. Right heart chamber measurements improve the diagnostic yield of echocardiography.

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.
