Objectives: Previous studies have shown that hyperbaric oxygen (HBO) is effective in reducing the severity of acute distal colitis (ADC). Ozone therapy (OT) reduces inflammation in several pathological conditions. We aimed to compare the effects of HBO therapy and OT in an experimental ADC rat model.
Materials And Methods: Forty rats were randomly divided into four groups: Sham, ADC, ADC + HBO, and ADC + OT. Rats in the sham group were given isotonic saline. In the remaining groups, ADC was created by intracolonic administration of 4% acetic acid. No treatment was given to the ADC group. The rats in the ADC + HBO and ADC + OT groups were given HBO and ozone treatments, respectively. The administration of acetic acid caused an inflammatory response in all animals. Distal colons and blood samples were obtained.
Results: The histopathological score was significantly higher in the ADC group compared to the other groups. The histopathological scores in the ADC + HBO and ADC + OT groups were significantly lower compared to the ADC group (both p < 0.001). The most pronounced therapeutic effect was observed in the ADC + OT group. Malondialdehyde and neopterin levels and superoxide dismutase and glutathione peroxidase activities in the ADC group were significantly higher compared to the other groups (p < 0.001).
Conclusion: Our data showed that the therapeutic effect of OT is more pronounced than that of HBO therapy. Its possible effect is by means of decreasing inflammation, edema, and oxidative stress. These findings also suggest that it is possible to improve the outcome of ADC by using ozone therapy as an adjuvant therapy.

Psychological stress may affect skin barrier homeostasis and slow down its recovery. Therefore, we aimed to examine the association between psychological stress levels and natural moisturizing factor (NMF) levels in the stratum corneum (SC). NMF levels were determined in the SC of 25 third-year and 25 sixth-year medical students in two periods (stressful and non-stressful) using the tape stripping method, high-performance liquid chromatography, and spectrophotometry.

Background: SL-172154 is a hexameric fusion protein adjoining the extracellular domain of SIRPα to the extracellular domain of CD40L via an inert IgG-derived Fc domain. In preclinical studies, a murine equivalent SIRPα-Fc-CD40L fusion protein provided superior antitumor immunity in comparison to CD47- and CD40-targeted antibodies. A first-in-human phase I trial of SL-172154 was conducted in patients with platinum-resistant ovarian cancer.

Introduction: Although the administration of activated charcoal (AC) is considered safe, the associated risk of pulmonary aspiration explains certain reluctance of physicians to use this procedure. The objective of this study was to analyse the rate of pulmonary aspiration in children receiving AC after accidental ingestion of a toxic substance.
Methods: We carried out a substudy of a multicentre prospective registry-based cohort study including children presenting with acute poisoning to 58 paediatric emergency department (EDs) members of the Spanish Society of Pediatric Emergency Medicine between 2008 and 2022 on certain previously designated days.

Background: The benefit of treatment with tyrosine kinase inhibitors targeting the epidermal growth factor receptor (EGFR-TKI) for lung adenocarcinoma (ADC), stratified by ethnicity, has not yet been fully elucidated.
Methods: We searched PubMed, Embase, and Cochrane databases for studies that investigated EGFR-TKI for lung ADC. We computed hazard ratios (HRs) or risk ratios (RRs) for binary endpoints, with 95% confidence intervals (CIs).
