Therapeutic Response of Alopecia Areata-Associated Nail Changes to Baricitinib.

Nail changes are seen in some individuals with alopecia areata, with the most common variants including pitting and trachyonychia. The nail findings are presumed to be due to the same lymphocytic infiltration seen in hair bulbs in individuals with AA. Baricitinib is an immunomodulatory drug that acts as a selective and reversible inhibitor of JAK proteins and is indicated for adult patients with moderate to severe rheumatoid arthritis who have not responded to other disease-modifying antirheumatic drugs.

Evaluating Reception Center Models for Radiation Response Screening Capacity and Throughput Predictions.

Introduction: The current fleet of nuclear reactors in the United States is mandated to provide evidence that surrounding jurisdictions can screen their populations should an incident occur. Capacity can be measured as throughput in reception centers used for screening. Due to the significant staffing and resources required to exercise screening capacity, most jurisdictions typically perform smaller exercises and use models to estimate their overall throughput.

Measurable radiation levels around individuals externally contaminated by nuclear fallout‡.

During the early response to large-scale radioactive contamination events, people who are potentially affected need to be screened for radioactive contamination and public health staff need to triage individuals who may need immediate decontamination. This is typically done by screening individuals for external contamination using ionising radiation detection equipment. In this study, spatially and temporally dependent isotopic compositions from a simulated nuclear detonation and Monte Carlo methods were used to relate contamination activity levels to the measurable radiation levels at select distances away from an individual with whole-body contamination.

Time Motion Studies for Conduct of Population Monitoring During Functional Radiological Exercises at Community Reception Centers.

Objective: The objectives of this study were to: validate current capacity estimates for radiological emergency response by collecting time motion observations from stations that would be used for screening and decontaminating populations, and use collected times to evaluate potential impact on current throughput calculations.

Methods: Time observations were collected at 11 functional radiation exercises across the country and aggregated for analysis for population monitoring activities, including contamination screening, decontamination, and registration. Collected times were compared to published estimates in current planning guidance, and evaluated to determine the suitability of using exercise observations to estimate throughput capacity.
