Measles Outbreak Associated with a Migrant Shelter - Chicago, Illinois, February-May 2024.

Measles, a highly contagious respiratory virus with the potential to cause severe complications, hospitalization, and death, was declared eliminated from the United States in 2000; however, with ongoing global transmission, infections in the United States still occur. On March 7, 2024, the Chicago Department of Public Health (CDPH) confirmed a case of measles in a male aged 1 year residing in a temporary shelter for migrants in Chicago. Given the congregate nature of the setting, high transmissibility of measles, and low measles vaccination coverage among shelter residents, measles virus had the potential to spread rapidly among approximately 2,100 presumed exposed shelter residents.

Refinements to the boundary transformation vector representation of attractor shape deformation to enhance system parameter identification.

A new method of quantifying parameter changes in chaotic systems using estimates of how the boundaries of Poincare sections deform was recently developed. Refinements that improve the number and quality of the boundary transformation vectors produced by this method are proposed and analyzed here. Collectively, these refinements offer the ability to better match closely spaced linear segments of Poincare sections typical of fractal geometry, better handle boundary gaps, and more uniformly sample the boundary, resulting in additional data.

An Interlaboratory Comparison Study of Regulated and Emerging Mycotoxins Using Liquid Chromatography Mass Spectrometry: Challenges and Future Directions of Routine Multi-Mycotoxin Analysis including Emerging Mycotoxins.

The present interlaboratory comparison study involved nine laboratories located throughout the world that tested for 24 regulated and non-regulated mycotoxins by applying their in-house LC-MS/MS multi-toxin method to 10 individual lots of 4 matrix commodities, including complex chicken and swine feed, soy and corn gluten. In total, more than 6000 data points were collected and analyzed statistically by calculating a consensus value in combination with a target standard deviation following a modified Horwitz equation. The performance of each participant was evaluated by a z-score assessment with a satisfying range of ±2, leading to an overall success rate of 70% for all tested compounds.

Boundary transformation representation of attractor shape deformation.

Detecting parameter changes in chaotic systems depends on characterizing the deformation of the strange attractor. Here, we present a new method for comparing the geometry of two attractors by examining their boundaries in 2D via shape context analysis. Poincaré sections for each attractor are sampled along their outer limits, and a boundary transformation is computed that warps one set of points into the other.

An approach to discussing personal and social identity terminology with patients.

As the United States of America becomes more socially diverse, it is more important now than ever for health care providers to become more aware of their patients' social identities. It is imperative that providers engage with their patients and see how each of them identifies personally in relation to social construction terminology. As with the terminology of human anatomy, there is a vast and diverse vocabulary concerning the anatomy of society, which is also clinically relevant to health care providers.
