Hyperbaric oxygen (HBO2) therapy involves the inhalation of pure oxygen in a pressure chamber under increased ambient pressure. Recent research indicates that circulating small extracellular vesicles (sEVs) play important roles in human physiology and pathology. Therefore, the objective of this pilot study was to monitor the impact of HBO2 therapy on the levels of circulating sEVs in the serum of patients with necrotizing soft-tissue infections (NSTI), aseptic bone necrosis (ABN) or idiopathic sudden sensory neural hearing loss (ISSNHL). ⋯ The increase in the levels of sEVs in ISSNHL may be evidence for both the intended reduction of inflammation as a result of steroid therapy and the inhibitory effect of oxidative stress induced by HBO2 therapy. Thus, sEVs released during HBO2 therapy might play an important biological role in mediating the response to therapy and might be a promising approach to gain further insights into the therapeutic efficacy of HBO2 therapy.

microRNAs (miRs) have been reported as blood-based noninvasive indicators for the diagnosis of various diseases. However, the utility of whole blood-based miRs in the diagnosis of intracranial aneurysm (IA) is still not clear. The present study aimed to examine miR expression profiling in the peripheral whole blood of IA patients and healthy controls. ⋯ miR-21 combined with miR-92 could be considered as a potential biomarker for IA screening.

The ITGB6 gene encoding a protein that can regulate the integrin αvβ6 heterodimer protein expression in different status was shown to play an important role in multiple human cancers, such as brain cancer, colon cancer and oral cancer, and is related to clinical progression. This study aims to explore the function and the mechanism of the ITGB6 gene or protein in pancreatic cancer. ⋯ Our data suggest that ITGB6 is associated with pancreatic cancer malignant progression. Hence, ITGB6 may serve as a potential target of pancreatic cancer for future research, and further study is needed.

Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD). Increased Lp(a) concentration > 30 mg/dl (75 nmol/l) and especially >50 mg/dl (125 nmol/l) may cause faster atherosclerosis, being an important and underdiagnosed residual cardiovascular risk factor. Thus, there is a need to characterize further the clinical phenotypes in patients at risk for ASCVD with high Lp(a) levels now and during follow-up, while also looking for the possible impact of geographical differences. ⋯ In Poland, the largest representative of Central and Eastern European countries, 27% of patients at very high cardiovascular risk with established ASCVD experience additional risk related to an elevated Lp(a) level, with every second patient having CCS. Interestingly, only two factors were significantly related to elevated Lp(a) levels: lower Hb values and higher platelet count. However, the clinical relevance of these results needs confirmation.

Long non-coding RNAs (lncRNAs) functioning as competing endogenous RNAs (ceRNAs) play critical roles in tumour progression. However, prognosis-related ceRNA networks in lung adenocarcinoma (LUAD) have not been well characterised. ⋯ This ceRNA network contributes to understanding the pathogenesis of LUAD. Furthermore, the molecules in the network are valuable predictive factors for LUAD prognosis as well as potential therapeutic biomarkers.
