Thrombosis Prophylaxis and Mortality Risk among Critically Ill Adults.
The optimal approach for managing increased risk of VTE among critically ill adults is unknown. ⋯ These findings support a recommendation for prophylactic anticoagulation therapy in preference to mechanical device prophylaxis for critically ill adult patients who do not have a contraindication to anticoagulation.

Changes in medical practice, such as retiring, selling a practice, and switching employment, have significant legal impacts on physicians. These decisions should be carefully analyzed prior to being made. Physicians who do not make decisions in a well-considered manner may face economic penalties, licensure sanctions, and/or other legal issues. ⋯ Within these topics, sources of physicians' legal and ethical obligations are examined, including possible resolutions to identified issues. Not all changes affect physicians in the same manner. This article further considers how these important legal issues may impact differently situated physicians, such as retiring physicians vs transitioning physicians and physicians employed by groups or hospital systems vs physicians in solo practice.

Lung transplantation reduces mortality in patients with end-stage lung disease; however, only approximately 21% of lungs from potential donor patients undergo transplantation. A large number of donor lungs become categorized as unsuitable for lung transplantation as a result of lung injury around the time of brain death. Limiting this injury is key to increasing the number of successful lung procurements and subsequent transplants. This narrative review by a working group of pulmonologists, respiratory therapists, and lung transplant specialists elucidates principles of mechanical ventilatory support that can be used to limit lung injury in potential lung donor patients and examines the implementation of protocolized strategies in enhancing the procurement of donor lungs for transplantation.

OSA is highly prevalent in children and usually initially treated by adenotonsillectomy. Nonsurgical alternatives for mild OSA primarily consisting of antiinflammatory approaches have emerged, but their efficacy has not been extensively assessed. ⋯ A combination of ICS + OM as initial treatment of mild OSA appears to provide an effective alternative to adenotonsillectomy, particularly in younger and nonobese children. These results support implementation of multicenter randomized trials to more definitively establish the role of ICS + OM treatment in pediatric OSA.

Short telomeres are frequently identified in patients with idiopathic pulmonary fibrosis (IPF) and its inherited form, familial interstitial pneumonia (FIP). We identified a kindred with FIP with short telomeres who did not carry a mutation in known FIP genes TERT or hTR. We performed targeted sequencing of other telomere-related genes to identify the genetic basis of FIP in this kindred. ⋯ Polymerase chain reaction-based sequencing of NOP10 , TINF2 , NHP2 , and DKC1 revealed that both affected siblings shared a novel A to G 1213 transition in DKC1 near the hTR binding domain that is predicted to encode a Thr405Ala amino acid substitution. hTR levels were decreased out of proportion to DKC1 expression in the T405A DKC1 proband, suggesting this mutation destabilizes hTR and impairs telomerase function. This DKC1 variant represents the third telomere-related gene identified as a genetic cause of FIP. Further investigation into the mechanism by which dyskerin contributes to the development of lung fibrosis is warranted.
