Observational Study
Safety and Effectiveness of Clofazimine for Primary and Refractory Nontuberculous Mycobacterial Infection.
Clofazimine is an antimicrobial agent that has activity in vitro against mycobacteria. Increasingly, it has been used for the treatment of nontuberculous mycobacteria (NTM), despite limited data supporting its use in this setting. The objective of this study was to evaluate the safety, tolerability, and clinical outcomes associated with clofazimine in patients with NTM infection. ⋯ Clofazimine was a safe, reasonably tolerated, and active oral drug for NTM infection in our heterogeneous population of pediatric and adult CF and non-CF patients. It should be considered as an alternative drug for treatment of NTM disease.

The call for meaningful patient and family engagement in research has recently gained considerable momentum. This article defines patient and family engagement broadly and specifically in clinical research. ⋯ Through our experiences, we share our insights regarding the perceived opportunities and also highlight some challenges associated with engaging patients and family engagement in critical care research. Although "engagement science" is in its infancy, engaging patients and families in research holds promise as a novel research paradigm that will not only provide new insights into the questions, methods, and outcomes used in ICU research, but it will also make investments in research more accountable and ensure a strong "patient- and family-centered focus" of our research.

Chronic cough is a significant problem, and in many patients cough remains refractive to both disease-specific therapies and current cough-suppressing medicines, creating a need for improved antitussive therapies. Most patients with chronic cough also display heightened sensitivity so that they experience a persistent sense of the need to cough, and often innocuous stimuli can trigger their coughing. This hypersensitivity underpins the newly described concept of cough hypersensitivity syndrome (CHS), a term that encapsulates the notion of common underlying mechanisms producing neuronal activation, sensitization and/or dysfunction, which are at the core of excessive coughing. ⋯ However, efforts to achieve this have been slower than expected, in part because of some significant challenges and limitations translating current cough models. In this review, we summarize recent advances in our understanding of the sensory circuits innervating the respiratory system that are important for cough, how cough sensory pathways become hypersensitive, and some of the recently described neural targets under development for treating chronic cough. We present the case that better use of current cough models or the development of new models, or both, is ultimately needed to advance our efforts to translate the discovery of basic cough mechanisms into effective medicines for treating patients with chronic cough.
