Objectives: Using electronic health records, we derived and internally validated a prediction model to estimate risk factors for long COVID and predict individual risk of developing long COVID.

Design: Population-based, retrospective cohort study.

Setting: Scotland.

Co(CH) ( = 1-6) complexes produced with laser vaporization in a supersonic molecular beam are studied with infrared photodissociation spectroscopy and computational chemistry. Infrared spectra are measured in the C-H stretching region using the method of tagging with argon atoms to enhance the photodissociation yields. C-H stretch vibrations for all clusters studied are shifted to lower frequencies than those of the well-known acetylene vibrations from ligand → metal charge transfer interactions.

Purpose: Understanding sociodemographic factors associated with poor visual outcomes in children with juvenile idiopathic arthritis-associated uveitis may help inform practice patterns.

Patients And Methods: Retrospective cohort study on patients <18 years old who were diagnosed with both juvenile idiopathic arthritis and uveitis based on International Classification of Diseases tenth edition codes in the Intelligent Research in Sight Registry through December 2020. Surgical history was extracted using current procedural terminology codes.

Article Synopsis
  • A study conducted in Scotland aimed to determine how common long COVID is among adults and to identify the risk factors linked to its development.
  • Out of nearly 4.7 million participants, about 81,219 (1.7%) were found to have long COVID, with various methods yielding different case counts, primarily due to limited overlap among the identification methods.
  • Factors associated with a higher likelihood of long COVID included being female, being between 38-67 years old, being overweight or obese, having pre-existing health conditions, being immunosuppressed, shielding from infection, or being hospitalized shortly after testing positive for COVID-19.

Platinum cation complexes with multiple acetylene molecules are studied with mass spectrometry and infrared laser spectroscopy. Complexes of the form Pt(CH) are produced in a molecular beam by laser vaporization, analyzed with a time-of-flight mass spectrometer, and selected by mass for studies of their vibrational spectroscopy. Photodissociation action spectra in the C-H stretching region are compared to the spectra predicted for different structural isomers using density functional theory.
