Novel neurodigital interface reduces motion sickness in virtual reality.

Virtual reality (VR) is a computer-created 3D environment with a focus on realistic scenes and pictures created for entertainment, medical and/or educational and training purposes. One of the major side effects of VR immersion reported in the scientific literature, media and social media is Visually Induced Motion Sickness (VIMS), with clinical symptoms such as disorientation, nausea, and oculomotor discomfort. VIMS is mostly caused by the discrepancy between the visual and vestibular systems and can lead to dizziness, nausea, and disorientation.

Predicting no-reflow phenomenon prior to primary percutaneous coronary intervention using a novel probability risk score derived from clinical and angiographic parameters.

Objective: We aimed to create a clinically usable probability risk score for prediction of no-reflow (NRF) phenomenon prior to primary percutaneous coronary intervention (PPCI).

Patients And Methods: This single-center and retrospective study included 1254 patients with acute ST-segment elevation myocardial infarction (STEMI) who underwent PPCI. Patients were randomly assigned into two groups in the ratio 2:1, the derivation dataset (n=840) and validation dataset (n=414).

THE REGULATION ROLE OF CAROTID BODY PERIPHERAL CHEMORECEPTORS IN PHYSIOLOGICAL AND PATHOPHYSIOLOGICAL CONDITIONS.

Introduction: The major oxygen sensors in the human body are peripheral chemoreceptors. also known as interoreceptors- as connected with internal organs, located in the aortic arch and in the body of the common carotid artery. Chemoreceptor function under physiological conditions.

Disturbance of oxidative balance in the first trimester of spontaneous abortions.

Background/aim: Pregnancy is defined as a condition of increased oxidative stress. The aim of this research was to determine the intensity of pro-oxidative processes and the content of GSH, as well as antioxidative enzymes: superoxide dismutase (SOD), catalase (CAT), gluthatione peroxidase (GSH-Px), and the total antioxidative status (TAS) in patients with spontaneous abortions.

Methods: A total of 120 patients were involved in the research (70 spontaneous abortions and 50 healthy pregnancies).

Very late stent thrombosis of bare-metal coronary stent nine years after primary percutaneous coronary intervention.

Introduction: Stent thrombosis (ST) in clinical practice can be classified according to time of onset as early (0–30 days after stent implantation), which is further divided into acute (< 24 hours) and subacute (1–30 days), late (> 30 days) and very late (> 12 months). Myocardial reinfaction due to very late ST in a patient receiving antithrombotic therapy is very rare, and potentially fatal. The procedure alone and related mechanical factors seem to be associated with acute/subacute ST.
