Background: The efficiency of the application of normobaric interval hypoxic therapy and enteral oxygen therapy for the treatment of the patients suffering from chronic obstructive pulmonary disease remains to be confirmed.
Aim: The objective of the present study was the identification of the pathophysiological mechanisms responsible for the efficiency of normobaric interval hypoxic therapy and enteral oxygen therapy in the patients presenting with a chronic obstructive pulmonary disease.
Material And Methods: A total of 230 patients at the age from 45 to 60 years were examined. All of them presented with chronic obstructive pulmonary disease (COPD). 150 patients were given a course of normobaric interval hypoxic therapy and enteral oxygen therapy while the remaining 80 ones constituted the control group.
Results: It was shown that the combined application of normobaric interval hypoxic therapy and enteral oxygen therapy provided an effective tool for the correction of the health status in the patients with chronic obstructive pulmonary disease. This method allowed to improve arterial blood supply with oxygen, increase the blood hemoglobin level and its oxygen capacity, augment oxygen tension and content in the arterial blood. The combination of the intake of oxygen cocktails and hypoxic therapy resulted in the improvement of metabolic processes in the lungs manifested as the alteration in the characteristics of the condensate of the exhaled air. The decrease in the content of malondialdehyde gave evidence of the reduction of lipid peroxidation while the enhanced activities of glutathione peroxidase and superoxide dismutase in blood confirmed the activation of the antioxidant system. The improved oxygen supply at all stages of its mass transfer along with the resulting improvement of oxygen utilization by the tissues was responsible for the reduction of hypoxia in the bronchial tree and lung tissue.
Conclusion: The present study confirmed the high effectiveness of the combined application of normobaric interval hypoxic therapy and enteral oxygen therapy for the rehabilitation of the patients presenting with chronic obstructive pulmonary disease.

Importance: Gastrointestinal complications are common perioperative complications in children with congenital heart disease (CHD), and as near-infrared reflectance spectroscopy (NIRS) provides a non-invasive, real-time monitoring of regional tissue oxygenation, we envisioned monitoring and preventing the development of gastrointestinal complications through the use of NIRS.
Objective: To assess the utility of NIRS for predicting gastrointestinal complication risks and determining optimal initial feeding times in infants post-cardiac surgery.
Methods: This retrospective study included 65 infants with CHD treated at our hospital from January 2021 to January 2022.

Background: Patients with severe respiratory failure have high mortality and need various interventions. However, the impact of intensivists on treatment choices, patient outcomes, and optimal intensivist staffing patterns is unknown. In this study, we aimed to evaluate treatments and clinical outcomes for patients at board-certified intensive care training facilities compared with those at non-certified facilities.

Background/objectives: Identifying nutritional interventions in extremely low-birth-weight (ELBW) infants (<1000 g) that are associated with favorable clinical outcomes is important. Delayed enteral feeding initiation (>3 days) has been associated with increased odds of developing morbidity. Therefore, the aim of this study is to evaluate the relationship between hour of life at enteral feeding initiation and associated clinical outcomes.

Article Synopsis
- The study aimed to assess the oxygen levels in the brains and digestive systems of premature infants with a specific type of heart disease, using a method called near infrared spectroscopy (NIRS).
- Researchers monitored 24 infants over 48 hours, comparing those with congenital heart disease (CHD) to healthy controls.
- Results showed that infants with CHD had significantly lower oxygen levels in both the brain and digestive areas compared to the control group, indicating potential health issues related to their condition.
