VITALS
Key clinical point: The American College of Chest Physicians and the Canadian Thoracic Society have issued a guideline for prevention of acute exacerbations of COPD.
Major finding: COPD exacerbations are acute, trajectory changing, and often deadly manifestations of a chronic disease.
Data source: A comprehensive literature review on prevention of acute COPD exacerbations and a compilation of 33 recommendations and suggestions for clinicians in clinical practice.
Disclosures: The American College of Chest Physicians, the Canadian Thoracic Society, and the American Thoracic Society supported the project. Dr Criner reported having no relevant financial disclosures; his associates reported ties to numerous industry sources.

VITALS
Key clinical point: GI symptoms were linked with specific motor and nonmotor features of Parkinson disease and related disorders.
Major finding: Constipation was the most common symptom among all three parkinsonian disorders.
Data source: Multicenter, cross-sectional survey of 473 patients with Parkinson disease, atypical parkinsonism, or vascular parkinsonism.
Disclosures: The Collaborative Clinical Research Fund of Boramae Medical Center partially funded the work. The authors declared no relevant conflicts of interest.

VITALS
Key clinical point: An aerosolized measles vaccine was immunogenic but inferior to the subcutaneous vaccine at inducing seropositivity among babies residing in rural India.
Major finding: The primary endpoint—seropositivity for antibodies against measles at 91 days after vaccination—was 85.4% for aerosolized vaccine and 94.6% for subcutaneous.
Data source: An open-label, randomized noninferiority trial comparing aerosolized vs subcutaneous measles vaccination in 2,004 infants ages 9 to 11.9 months in villages in India.
Disclosures: This study was funded by the Bill and Melinda Gates Foundation. The Serum Institute of India provided vaccines free of charge, and Aerogen provided the delivery devices free of charge. Dr Low reported several grants plus monies paid to her institution from the World Health Organization for projects about vaccines and sexually transmitted infections; her associates reported ties to the Serum Institute of India, Aerogen, and Dance Biopharm. One associate has a patent pending on an aerosol device licensed to Novartis and another has a patent pending related to vaccine nebulizers.

4. Unrecognized Diabetes Common in Acute MI

VITALS
Key clinical point: Many patients presenting with acute MI had unrecognized diabetes, which, in most cases, remained undiagnosed, untreated, and unrecorded.
Major finding: Of 2,854 (10%) patients enrolled in an MI registry, 287 had A1C levels of 6.5% or higher on routine laboratory testing during hospitalization for acute MI, but treating physicians recognized only 101 of these cases of diabetes (35%).
Data source: A retrospective cohort study involving 2,854 adults presenting with acute MI to 24 US medical centers in a 3.5-year period.
Disclosures: This study was sponsored by the National Heart, Lung, and Blood Institute and supported by a research grant from Genentech. Dr Arnold reported receiving honoraria from Novartis; her associates reported ties to numerous industry sources.

5. Methotrexate and Biologics Linked to Higher Zoster Risk in Psoriasis
To take the posttest, go to: https://bit.ly/1AZScyF

VITALS
Key clinical point: The combination of methotrexate and biologics for the treatment of psoriasis may increase risk for herpes zoster.
Major finding: Combination therapy with both biologic medications and methotrexate was associated with a significant 66% increase in the incidence of herpes zoster over more than 11 years of follow-up.
Data source: Analysis of medical records for 95,941 patients with psoriasis.
Disclosures: One author reported consultancies and research grants from a range of pharmaceutical companies. There were no other disclosures.
