Abnormally low pO2 and oxygen saturations on arterial blood gases (ABGs) test have been reported in the patients who have very high WBC and platelet counts; generally in the setting of hematological malignancies. This is presumably related to the consumption of oxygen by the active cellular elements in the arterial blood sample during the process of ABG analysis. This phenomenon which is also known as "spurious hypoxemia" or "oxygen steal" or "leukocyte/platelet larceny" is suspected when there is no other obvious explanation for hypoxemia on ABG, especially in the setting of normal oxygen saturations by the pulse oximetry. It is important for medical professionals to be aware of this condition so that appropriate workup and triage can be performed on such patients, which may otherwise lead to unnecessary hospitalization and escalation of care.

Objective: To analyze the results of nocturnal breathing parameters during sleep based on nocturnal pulse oximetry and to study of characteristics of external respiration in genetically confirmed patients with dystrophic myotonia (DM).
Material And Methods: The subjects of the study were patients with genetically confirmed DM types 1 and 2 who were hospitalized in the neurological departments of the Republican Scientific and Practical Center for Neurology and Neurosurgery. The clinical picture of the disease, comorbidities, sleep questionnaires, laboratory tests, overnight pulse oximetry and spirometry were performed and analyzed.
The Safety and Late Hemodynamics of Donor Cardiac Undersizing in Heart Transplantation.

Department of Cardiac Surgery, Vanderbilt University Medical Center, Nashville Tennessee.
Background: Predicted heart mass ratio (PHMr) has become the standard donor-recipient size matching method in heart transplantation. While utilization of small PHMr hearts is associated with increased one-year mortality, the underlying mechanisms and time horizon of mortality remain uncertain.
Methods: A single institution analysis of isolated heart transplant recipients (01/2019-7/2022) was performed (N=334).

Study Objective: To determine whether individualized fraction of inspired oxygen (iFiO) improves pulmonary atelectasis after elective laparoscopic colorectal surgery relative to 60 % FiO.
Design: This was a single-center, prospective, randomized study.
Setting: This study was conducted in a single tertiary care hospital in China.
Comparison of Ketamine/Diazepam and Tiletamine/Zolazepam Combinations for Anaesthesia Induction in Horses Undergoing Partial Intravenous Anaesthesia (PIVA): A Retrospective Clinical Study.

Department of Veterinary Medical Sciences, University of Bologna, 40126 Bologna, Italy.
The aim of this retrospective clinical study was to compare the combinations of ketamine/diazepam (KD group) and tiletamine/zolazepam (TZ group) for the induction of general anaesthesia in horses undergoing elective surgery. The data from the clinical and the anaesthetic records of 138 horses from 2021 to 2023 were evaluated, and the horses were divided in two groups: KD ( = 60) and TZ ( = 72). The horses were premedicated with romifidine and methadone IV; anaesthesia was induced with ketamine/diazepam for the KD group and tiletamine/zolazepam for the TZ group and was maintained with isoflurane and a constant rate infusion of romifidine.

The separation of oxygen (O) and nitrogen (N) from air is a process of utmost importance nowadays, as both species are vital for numerous fundamental processes essential for our development. Membranes designed for their selective molecule separation have become the materials of choice for researchers, primarily due to their ease of use. The present study proposes grazynes, 2D carbon-based materials consisting of and C atoms, as suitable membranes for separating O and N from air.
