Comparative Study
Risk of mycobacterial infections associated with rheumatoid arthritis in Ontario, Canada.
Patients with rheumatoid arthritis (RA) are at increased risk of TB. Little is known about the risk of nontuberculous mycobacteria (NTM) disease in these patients. We sought to ascertain the rate of NTM infection and TB in all residents of Ontario, Canada, with and without RA. ⋯ Mycobacterial infections are more common in Ontarians with RA, with NTM disease more likely than TB. NTM disease is associated with an increased risk of death in patients with RA. Given the rising rates of NTM disease worldwide, determining whether this risk is due to the use of immunosuppressive medications vs RA itself is an important objective for future research.

This article describes the curricular milestones and entrustable professional activities for trainees in pulmonary, critical care, or combined fellowship programs. Under the Next Accreditation System of the Accreditation Council for Graduate Medical Education (ACGME), curricular milestones compose the curriculum or learning objectives for training in these fields. Entrustable professional activities represent the outcomes of training, the activities that society and professional peers can expect fellowship graduates to be able to perform unsupervised. ⋯ After consensus was achieved using the Delphi process, the document was revised with input from the sponsoring societies and program directors. The resulting lists can serve as a roadmap and destination for trainees, program directors, and educators. Together with the reporting milestones, they will help mark trainees' progress in the mastery of the six ACGME core competencies of graduate medical education.

The efficacy and safety of anticoagulation with use of vitamin K antagonists (VKAs) is highly dependent on the quality of anticoagulation control as reflected by the average time in a therapeutic range of 2.0 to 3.0. A clinical dilemma is trying to predict which anticoagulation-naive patients with atrial fibrillation (AF) would do well on a VKA (with a time in therapeutic range > 70%) and which are less likely to do well on a VKA but could be managed with novel oral anticoagulants. ⋯ We demonstrate that the SAMe-TT₂R₂ score was predictive for an increasing risk of stroke/TE, severe bleeding, major BARC bleeding, and death, reflecting poor anticoagulation control (and labile INRs) among patients with AF given VKAs.

The risk of VTE before anticancer therapy in patients with lung cancer is not well defined. ⋯ The prevalence of VTE was high in patients with newly diagnosed lung cancer. In patients with lung cancer, the factors associated with DVT might be different from those associated with PE. An elevated CEA level might facilitate the identification of patients at a higher risk of developing PE.

Observational Study
B-Mode ultrasound assessment of diaphragm structure and function in patients with COPD.
Electromyographic evaluation of diaphragmatic neuromuscular disease in patients with COPD is technically difficult and potentially high risk. Defining standard values for diaphragm thickness and thickening ratio using B-mode ultrasound may provide a simpler, safer means of evaluating these patients. ⋯ In patients with COPD presenting for evaluation of coexisting neuromuscular respiratory weakness, the same values established for healthy control subjects serve as the baseline for comparison. This knowledge expands the role of ultrasound in evaluating neuromuscular disease in patients with COPD.
