Deshaun Watson said before the 2017 draft that he talked to the Bears

Texans quarterback Deshaun Watson raised plenty of eyebrows on Friday when he tweeted, "The Bears NEVER ONCE talked to me" before the 2017 NFL draft. But that's not what Watson said at the time. Prior to the 2017 draft, Watson said in an interview with Rich Eisen that the Bears had talked to him. "I've [more]

Follow-up Testing Among Children With Elevated Screening Blood Lead Levels

Interview with Alex R. Kemper, MD, MPH, MS, author of Follow-up Testing Among Children With Elevated Screening Blood Lead Levels, published in the May 11 issue of JAMA, the Journal of the American Medical Association. Summary Points: 1. About half the children (six years and younger) with elevated blood lead levels did not receive follow up testing. 2. Nonwhite children, and those living in urban as well as high-risk lead settings, were less likely to receive follow up testing compared to their counterparts. 3. Follow-up testing for children with high blood lead levels is essential for managing lead poisoning and for maximizing cognitive development. 4. Interventions are needed to overcome disparities in care.

Update on the Treatment of Tuberculosis and Latent Tuberculosis Infection

Interview with Henry M. Blumberg, MD, author of Update on the Treatment of Tuberculosis and Latent Tuberculosis Infection, published in the June 8 issue of JAMA, the Journal of the American Medical Association. Summary Points: 1. Tuberculosis is a public health problem. The responsibility for prescribing an appropriate regimen and assuring that treatment is completed is assigned to the public health program or the treating physician, not the patient. 2. Directly observed therapy is recommended for all patients being treated for active TB, this will necessitate the need for greater collaboration between the treating physician and the public health department. 3. Initial therapy for newly diagnosed patients with tuberculosis consists of a 4-drug regimen including isoniazid, rifampin, pyrazinamide and ethambutol. 4. Testing for latent TB infection should be targeted at those who are at increased risk of progression to active TB. 5. Despite its limitations, the tuberculin skin test remains the most commonly used test for the diagnosis of latent TB infection; newer diagnostic tests for latent TB infection are on the horizon. 6. Active tuberculosis should be excluded before beginning treatment for latent tuberculosis infection. 7. Nine months of isoniazid is the preferred therapy for the treatment of latent TB infection.

Combined Tetanus, Diphtheria, and 5-Component Pertussis Vaccine for Use in Adolescents and Adults

Interview with Michael E. Pichichero, MD, author of Combined Tetanus, Diphtheria, and 5-Component Pertussis Vaccine for Use in Adolescents and Adults, published in the June 22/29 issue of JAMA, the Journal of the American Medical Association. Summary Points: 1. Need: The combined tetanus-diphtheria 5-component pertussis vaccine is needed; There has been a 300% increase of pertussis among US adolescents in the last three years. 2. Safety: The combined tetanus-diphtheria 5-component pertussis vaccine is safe, as the reactions are the same as the tetanus vaccine. 3. Universal: On June 30, 2005, the American Academy of Pediatrics (ASAP), America Academy of Family Physicians (AFAR), and the Advisory Committee on Immunization Practices (ACID) all recommended the universal use of the combined tetanus-diphtheria 5-component pertussis vaccine or its competitor vaccine for adolescents.

Clinical Decision Support and Appropriateness of Antimicrobial Prescribing: A Randomized Trial

Interview with Matthew H. Samore, MD, author of Clinical Decision Support and Appropriateness of Antimicrobial Prescribing: A Randomized Trial, published in the November 9 issue of JAMA, the Journal of the American Medical Association. Summary points: 1. Repetitive use of a diagnostic and treatment algorithm to ingrain new prescribing habits was a valuable part of this practice change intervention. 2. Clinical decision support systems (CDSS) are feasibly implemented in practice settings that lack electronic medical records, including rural communities. 3. CDSS needs to be integrated with tools that save clinicians' time to be sustainable.
