BACKGROUND AND OBJECTIVES Cystic fibrosis (CF) screen–positive infants with an inconclusive diagnosis (CFSPID) are infants in whom sweat testing and genetic analysis does not resolve a CF diagnosis. Lack of knowledge about the health outcome of these children who require clinical follow-up challenges effective consultation. Early predictive biomarkers to delineate the CF risk would allow a more targeted approach to these children. METHODS Prospective, longitudinal, multicenter, Canada-wide cohort study of CF positive–screened newborns with 1 to 2 cystic fibrosis transmembrane conductance regulator gene variants, of which at least 1 is not known to be CF-causing and/or a sweat chloride between 30 and 59 mmol/L. These were monitored for conversion to a CF diagnosis, pulmonary, and nutritional outcomes. RESULTS The mean observation period was 7.7 (95% confidence interval 7.1 to 8.4) years. A CF diagnosis was established for 24 of the 115 children with CFSPID (21%) either because of reinterpretation of the cystic fibrosis transmembrane conductance regulator genotype or because of increase in sweat chloride concentration ≥60 mmol/L. An initial sweat chloride of ≥40 mmol/l predicted conversion to CF on the basis of sweat testing. The 91 remaining children with CFSPID were pancreatic sufficient and showed normal growth until school age. Pulmonary function as well as lung clearance index in a subgroup of children with CFSPID were similar to that of healthy controls. CONCLUSIONS Children with CFSPID have good nutritional and pulmonary outcomes at school age, but rates of reclassifying the diagnosis are high. The initial sweat chloride test can be used as a biomarker to predict the risk for CF in CFSPID.

Respirologists and CPNG members provide similar respiratory management of DMD patients, but differ in timing of consultation and choice of tests for pulmonary function and SDB. Canadian practices differ from the American Thoracic Society and Centre for Disease Control guidelines.

Based on this long-term follow-up study, NiPPV use in infants appears to be a viable long-term ventilation strategy.

Burnout has attained epidemic proportions in all reaches of society. Only recently, has its impact in healthcare become a burning platform. Second victim syndrome, a consequence of an unforeseen adverse event, often precipitated by an error, can lead to a post-traumatic stress-like reaction, that is unique to healthcare workers. Often, the second victim suffers in silence, forced to rely on resilience. Peer support has been demonstrated to be beneficial in assisting healthcare workers in recovering from both burnout and second victim syndrome. Institutions and organizations must be more influential and responsive in supporting physicians and other healthcare workers in need.
