Colorectal cancer (CRC) patients undergoing chemotherapy often experience anemia, oxidative stress, and immune suppression, significantly impacting their quality of life and treatment outcomes. Normobaric oxygen (NBO) therapy, which delivers oxygen at atmospheric pressure with elevated oxygen concentration, has shown a potential to enhance erythropoiesis, reduce oxidative stress, and modulate immune function. However, its efficacy in CRC patients remains underexplored. This study aims to evaluate the effects of NBO exposures on (1) supporting erythropoiesis by measuring erythropoietin (EPO) levels and hypoxia-inducible factors (HIF-1α), (2) reducing oxidative stress and improving stress and emotional well-being, and (3) modulating immune function by assessing cytokine profiles. Secondary objectives include assessing the impact of NBO on patient-reported outcome measures (PROMs) such as stress, anxiety, depression, and quality of life. This is a prospective, randomized, double-blind, placebo-controlled clinical trial. A total of 254 CRC patients undergoing chemotherapy will be randomized 1:1 to receive either active NBO therapy (n=127) or placebo NBO therapy (n=127). The intervention consists of 10 NBO sessions over five weeks. Primary outcomes include biomarkers of erythropoiesis, oxidative stress, and immune response. Secondary outcomes assess quality of life and psychological well-being. Data will be collected at baseline, mid-intervention, post-intervention, and during two follow-up visits (3- and 6-months post-intervention). The study hypothesizes that NBO therapy will improve erythropoiesis, reduce oxidative stress, and enhance immune function in CRC patients, leading to improved quality of life and clinical outcomes. Findings from this trial may establish NBO as a novel supportive therapy for CRC patients undergoing chemotherapy.

The goal of this interventional, real world data study is to evaluate the impact of preservatives on the post-cataract ocular surface.
The main question is to learn about an effect of preservatives on the eye surface. The study aims to answer some important questions:
if the usage of preservatives has an impact on the eye surface healing process after cataract surgery
if patient comfort and quality of life improve more or more rapidly with preservatives-free eye drops.
Participants will be asked to undergo standard procedure of peri-cataract surgery care and in addition to survey about the ocular surface state.
Researchers will compare group that takes preservatives-free dexamethasone 0.1% with standard dexamethasone 0.01% solution to see if post-surgery eye surface healing properties differ from both groups.

Prospective, interventional, open, randomized, single-center, non-commercial clinical trial to optimize treatment and dosage of trametinib in juvenile patients with histiocytosis resistant to conventional therapy and without the BRAF gene mutation or after the failure of vemurafenib treatment.
