A diverse range of relaxation dynamics of trapped spin-states are observed in spin crossover (SCO) materials, including exponential, sigmoidal, stretched exponential, multi-step, and mixed kinetics. We reproduce and explain this full range of relaxation behaviours using a semi-empirical, semi-classical model that combines crystal field theory with elastic inter-molecular interactions. We show that frustrated intermolecular interactions, which are responsible for multistep thermal transitions, also lead to multiple energetically competitive ordered phases, even in systems that contain only one crystallographically distinct SCO site.

- This study examines the link between clinical and imaging features with hormonal subtypes, growth, and surgical treatment of incidental adrenal cortical adenomas (ACAs) in a cohort of patients from 2000 to 2016.
- Out of 1516 patients, various hormonal subtypes were identified, with factors like age, sex, and tumor size influencing these subtypes, while imaging measures like Hounsfield units (HU) were not significant predictors.
- The findings indicate younger age, larger tumor size, and increased growth were associated with a higher likelihood of needing adrenalectomy, especially for patients with mild autonomous cortisol secretion (MACS) and nonfunctioning adenomas (NFAs).
The 2023 Impact of Inflammatory Bowel Disease in Canada: Special Populations-IBD in Seniors.
J Can Assoc Gastroenterol
September 2023
Approximately one out of every 88 seniors has inflammatory bowel disease (IBD), and this is expected to increase in the future. They are more likely to have left-sided disease in ulcerative colitis, and isolated colonic disease in Crohn's disease; perianal disease is less common. Other common diagnoses in the elderly must also be considered when they initially present to a healthcare provider.

We aimed to better define this through a systematic review and meta-analysis.
Methods: We explored the impact of race or ethnicity on the likelihood of needing an IBD-related surgery, hospitalization, and emergency department visit.
