Randomized Controlled Trial Multicenter Study
Early Changes over Time in the Radiographic Assessment of Lung Edema (RALE) Score are Associated with Survival in Acute Respiratory Distress Syndrome.
The Radiographic Assessment of Lung Edema (RALE) score is associated with the severity of ARDS, and treatments targeted at reducing pulmonary edema such as conservative fluid management cause a reduction in RALE score over time. ⋯ The change in RALE during the first days after ARDS onset is independently associated with survival and may be useful as a surrogate end point in future clinical trials of new therapeutics in ARDS.

CHEST Reviews: Addressing reduced laboratory-based pulmonary function testing during a pandemic.
To reduce the spread of the severe acute respiratory syndrome coronavirus 2, many pulmonary function testing (PFT) laboratories have been closed or have significantly reduced their testing capacity. Because these mitigation strategies may be necessary for the next 6 to 18 months to prevent recurrent peaks in disease prevalence, fewer objective measurements of lung function will alter the diagnosis and care of patients with chronic respiratory diseases. PFT, which includes spirometry, lung volume, and diffusion capacity measurement, is essential to the diagnosis and management of patients with asthma, COPD, and other chronic lung conditions. ⋯ With these options comes important technical, privacy, ethical, financial, and medicolegal barriers that must be addressed. However, the coronavirus disease 19 pandemic also presents a unique opportunity to augment conventional testing by including innovative and emerging approaches to measuring lung function remotely in patients with respiratory disease. The benefits of such an approach have the potential to enhance respiratory care and empower patient self-management well beyond the current global pandemic.

Randomized Controlled Trial Multicenter Study
"A randomized trial of initiation of chronic non-invasive mechanical ventilation at home vs in-hospital in patients with Neuromuscular Disease and thoracic cage disorder": The Dutch Homerun Trial.
There is an increasing demand for home mechanical ventilation (HMV) in patients with chronic respiratory insufficiency. At present, noninvasive ventilation is exclusively initiated in a clinical setting at all four centers for HMV in the Netherlands. In addition to its high societal costs and patient discomfort, commencing HMV is often delayed because of a lack of hospital bed capacity. ⋯ This nationwide, multicenter study shows that HMV initiation at home is noninferior to hospital initiation, as it shows the same improvement in gas exchange and health-related quality of life. In fact, from a patient's perspective, it might even be a more attractive approach. In addition, starting at home saves over €3,200 ($3,793) per patient over a 6-month period.

Patients with autoimmune and/or inflammatory diseases (AIIDs) are prone to serious infectious complications such as Pneumocystis jirovecii pneumonia (PJP). In non-HIV patients, the prognosis is poorer, and diagnostic tests are of lower sensitivity. Given the low incidence of PJP in AIIDs, with the exception of granulomatosis with polyangiitis, and the non-negligible side effects of chemoprophylaxis, routine prescription of primary prophylaxis is still debated. ⋯ Effective alternative drugs such as atovaquone or aerosolized pentamidine could be used when trimethoprim-sulfamethoxazole is not tolerated or contraindicated. No standard guidelines are available to guide PJP prophylaxis in patients with AIIDs. This review covers the epidemiology, risk factors, and prevention of pneumocystis in the context of AIIDs.
