Target odorant detection in mixtures has been shown to become more difficult as the number of background odorants increases and falls below chance level in mixtures with 16 components. Our aim was to investigate target odorant detection in mixtures among healthy people and compare it between dysosmic patients and age- and gender-matched controls. Participants underwent extensive olfactory testing and performed two target odorant detection tasks.

Objectives: An olfactory perceptual fingerprint (OPF) defines one's olfactory perception using perceptual descriptor ratings (such as odor pleasantness, intensity) for a set of odors. OPFs have been shown to distinguish patients with COVID-related olfactory dysfunction (OD) and healthy controls with 86% accuracy. However, all participants rated the same odorants.

- * A study involved collecting T-shirts from individuals with PD and healthy participants to examine the differences in body odor, using 26 young women to rate the odors.
- * The results showed that the PD body odor was perceived as stronger and less pleasant, with about 80% of the participants able to distinguish it from an artificially created version, indicating that the artificial odor could not fully replicate the true PD body scent.
The sense of smell is based on sensory detection of the molecule(s), which is then further perceptually interpreted. A possible measure of olfactory perception is an odor-independent olfactory perceptual fingerprint (OPF) defined by Snitz et al. We aimed to investigate whether OPF can distinguish patients with olfactory dysfunction (OD) due to coronavirus disease (COVID-19) from controls and which perceptual descriptors are important for that separation.

- Erythrocytosis has various causes, and distinguishing between them is crucial, especially since polycythemia vera has clear criteria while other types do not.
- A study analyzed patients with non-clonal erythrocytosis over eight years using a three-step algorithm that confirmed true cases and identified secondary causes.
- Of the 116 patients studied, the majority were male, with 29% having secondary erythrocytosis, 13% idiopathic erythrocytosis, and 58% remaining incompletely characterized; common causes included sleep apnea and smoking, with significant treatment variations observed among patient groups.
