Implementation of a Professional Society Core Curriculum and Integrated Maintenance of Certification Program

Medical professional societies exist to foster collaboration, guide career development, and provide continuing medical education opportunities. Maintenance of certification is a process by which physicians complete formal educational activities approved by certifying organizations. The American Thoracic Society (ATS) established an innovative maintenance of certification program in 2012 as a means to formalize and expand continuing medical education offerings. This program is unique as it includes explicit opportunities for collaboration and career development in addition to providing continuing medical education and maintenance of certification credit to society members. In describing the development of this program referred to as the “Core Curriculum,” the authors highlight the ATS process for content design, stages of curriculum development, and outcomes data with an eye toward assisting other societies that seek to program similar content. The curriculum development process described is generalizable and positively influences individual practitioners and professional societies in general, and as a result, provides a useful model for other professional societies to follow

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Novel and Engaging Teaching Method for Pulmonary Physiology

BACKGROUND Pulmonary physiology is a challenging, necessary component of pediatric pulmonary fellowship education. Our pediatric pulmonology fellowship program provided this education utilizing a flipped classroom approach but satisfaction with the method was declining. Evidence suggests that adult learners benefit from an engaging lecture method, but no evidence exists to compare the flipped classroom approach to the engaging lecture approach for pulmonary physiology education. OBJECTIVE To develop the most effective physiology curriculum for pediatric pulmonary fellows by comparing the flipped classroom approach to an engaging lecture method. METHODS Five physiology teaching sessions were assigned to the flipped classroom method and 5 to the engaging lecture style. Anonymous surveys assessing satisfaction, utilizing a five-point Likert scale, were completed by fellows at the end of each session. An unpaired t -test was used to compare responses. RESULTS Seven pediatric pulmonary fellows enrolled in the study. The average attendance per session was 5 fellows. There was no significant difference in fellows’ perceived understanding of the assigned physiology topic prior to the flipped classroom versus engaging lecture sessions. Fellows’ perceived understanding of the topics improved after both session types, with significantly more improvement after the engaging lecture sessions. Fellows also reported that engaging lecture sessions were more useful and improved their test-taking confidence. They were more likely to recommend engaging lecture sessions to future pulmonary fellows. CONCLUSIONS Pediatric pulmonary fellows benefited from the use of the engaging lecture style for physiology education

Churg-Strauss syndrome in children: a clinical and pathologic review

Churg-Strauss syndrome is a vasculitis accompanied by asthma and eosinophilia. It is generally considered a disease of adults; occurrence in children has been reported infrequently. Here we report 2 pediatric patients with Churg-Strauss syndrome manifesting with prominent pulmonary involvement. One, a 16-year-old with a previous history of asthma, presented with pleuritic chest pain and a peripheral pulmonary nodule complicated by an eosinophilic pleural effusion. The other patient presented at age 6 with cough, weight loss, and radiographic infiltrates. Lung biopsies revealed elements characteristic of Churg-Strauss syndrome, including eosinophilic microabscesses and vasculitis. Three- and 5-year follow-up showed continued symptoms in both patients despite medical therapy. Both patients illustrate many of the typical features of Churg-Strauss syndrome. We report these cases to expand the scant knowledge about Churg-Strauss syndrome in pediatric patients and to heighten awareness that this serious disease may affect the pediatric population. The relevant literature on Churg-Strauss syndrome, with specific reference to childhood cases, is reviewed

Low‐fouling fluoropolymers for bioconjugation and in vivo tracking

The conjugation of hydrophilic low‐fouling polymers to therapeutic molecules and particles is an effective approach to improving their aqueous stability, solubility, and pharmacokinetics. Recent concerns over the immunogenicity of poly(ethylene glycol) has highlighted the importance of identifying alternative low fouling polymers. Now, a new class of synthetic water‐soluble homo‐fluoropolymers are reported with a sulfoxide side‐chain structure. The incorporation of fluorine enables direct imaging of the homopolymer by 19F MRI, negating the need for additional synthetic steps to attach an imaging moiety. These self‐reporting fluoropolymers show outstanding imaging sensitivity and remarkable hydrophilicity, and as such are a new class of low‐fouling polymer for bioconjugation and in vivo tracking
