Purpose: This study aimed to investigate the relationships between the clinical and polysomnographic findings and the olfactory test results in patients with obstructive sleep apnea syndrome (OSAS).
Methods: Four groups were established: non-snoring controls (group 1), non-apneic snorers (group 2), mild-moderate OSAS (group 3), and severe OSAS (group 4). The polysomnographic findings, otorhinolaryngologic findings, Epworth Sleepiness Scale (ESS), and Sniffin' Sticks olfactory test results of the four groups were compared. The relationships between the clinical data and the olfactory parameters were evaluated.
Results: Group 4 had the worst odor identification and discrimination scores. Non-apneic snorers also had worse odor parameters compared with the non-snorer controls. A significant negative correlation was found among the ESS, apnea-hypopnea index (AHI), mean arterial oxygen saturation, and odor identification and discrimination. Significant negative correlations were found between the tongue and tongue base sizes and among all olfactory parameters.
Conclusion: Our study revealed olfactory dysfunction in patients with OSAS. A strong negative correlation between the olfactory parameters and the severity of sleep apnea was also found. Olfactory tests may be used to predict the presence and severity of OSAS in the future.

Background: Vanadium (VAN) is a significant trace element, but its higher exposure is reported to cause severe organ toxicity. Tectochrysin (TEC) is a naturally derived flavonoid which demonstrates a wide range of pharmacological properties.
Aim: The current study was planned to assess the cardioprotective potential of TEC against VAN induced cardiotoxicity in rats via regulating biochemical, and histological profile.

Water systems can act as an important reservoir for Pseudomonas aeruginosa, which can pose public health risks during human contact. Carbapenem resistance is one of the most concerning resistances in P. aeruginosa making it a high-priority pathogen according to the World Health Organization (WHO), due to its ability to cause difficult-to-treat infections.

Ingestion of plastic can have negative health consequences for wildlife. However, our understanding of the physiological impacts of plastics is limited, often relying on opportunistic sampling. We partnered with Tasmanian Aboriginal seabird harvesters, wildlife rescue clinics, and parks managers, to collect >400 fledgling yula/short-tailed and flesh-footed shearwaters across a spectrum of body conditions.

Executive functions can be classified into processes of inhibition, working memory and shifting, which together support flexible and goal-directed behaviour and are crucial for both current and later-life outcomes. A large body of literature has identified distinct brain regions critical to performing each of these functions. These findings are however predicated on a piecemeal and single-task approach.

Background: Manual extraction of real-world clinical data for research can be time-consuming and prone to error. We assessed the feasibility of using natural language processing (NLP), an AI technique, to automate data extraction for patients with advanced lung cancer (aLC). We assessed the external validity of our NLP-extracted data by comparing our findings to those reported in the literature.
