Changes in Habitual Sleep Duration after Continuous Positive Airway Pressure for Obstructive Sleep Apnea.
Obstructive sleep apnea (OSA) can affect not only sleep quality but also sleep duration. Determining the therapeutic effects of continuous positive airway pressure (CPAP) on habitual sleep profiles may shed light on the impact of OSA on sleep duration. ⋯ Short-term CPAP did not affect habitual night sleep duration in the group as a whole but induced intraindividual changes in relation to phenotypic features of OSA. Clinical trial registered with www.umin.ac.jp (UMIN000012639).

Transbronchial cryobiopsy is an emerging technique for obtaining biopsies of lung parenchyma. Despite limited evidence of its safety and efficacy in direct comparison with other available biopsy procedures, pulmonologists are integrating this technique into clinical practice with the hope of avoiding the risks of surgical lung biopsy. ⋯ Transbronchial cryobiopsy may have diagnostic and safety limitations that are not yet well appreciated, given the state of the published medical literature. Major questions remain regarding the safest procedural protocol to be used when performing transbronchial cryobiopsy. Thorough planning and a high degree of caution are encouraged on first introduction of this technique into a clinical practice.

Placement of an indwelling pleural catheter is an established modality for symptom relief and pleurodesis in the treatment of malignant pleural effusion. Concerns remain regarding possible infectious complications, risk of hemorrhage, and the rate of pleurodesis with the use of pleural catheters in the treatment of hematologic malignancies. ⋯ Indwelling pleural catheters appear to be safe for patients with hematologic malignancies. Complications and the cumulative incidence of pleurodesis are comparable to those reported for patients with solid organ malignancies.
