Objective vs. Subjective Evaluation of Cognitive Performance During 0.4-MPa Dives Breathing Air or Nitrox
19 avril 2017, HE Bruxelles BrabantArticle scientifiqueBACKGROUND: Divers try to limit risks associated with their sport, for instance by breathing enriched air nitrox (EANx) instead of air. This double blinded, randomized trial was designed to see if the use of EANx could effectively improve cognitive performance while diving. METHODS: Eight volunteers performed two no-decompression dry dives breathing air or EANx for 20 min at 0.4 MPa. Cognitive ... -
Dive Risk Factors, Gas Bubble Formation, and Decompression Illness in Recreational SCUBA Diving: Analysis of DAN Europe DSL Data Base
10 mai 2017, HE Bruxelles BrabantArticle scientifiqueIntroduction: The popularity of SCUBA diving is steadily increasing together with the number of dives and correlated diseases per year. The rules that govern correct decompression procedures are considered well known even if the majority of Decompression Sickness (DCS) cases are considered unexpected confirming a bias in the "mathematical ability" to predict DCS by the current algorithms. Furthermore, ... -

Evidence of Heritable Determinants of Decompression Sickness in Rats
22 juillet 2017, HE Bruxelles BrabantArticle scientifiqueNTRODUCTION: Decompression sickness (DCS) is a complex and poorly understood systemic disease caused by inadequate desaturation following a decrease of ambient pressure. Strong variability between individuals is observed for DCS occurrence. This raises questions concerning factors that may be involved in the inter-individual variability of DCS occurrence. This study aimed to experimentally assess ... -

Or, les données concernant les décès en plongée mettent ... -
Patent Foramen Ovale (PFO), Personality Traits, and Iterative Decompression Sickness. Retrospective Analysis of 209 Cases
20 août 2017, HE Bruxelles BrabantArticle scientifiqueIntroduction: There is a need to evaluate the influence of risk factors such as patency of foramen ovale (PFO) or "daredevil" psychological profile on contra-indication policy after a decompression sickness (DCS). Methods: By crossing information obtained from Belgian Hyperbaric Centers, DAN Emergency Hotline, the press, and Internet diving forums, it was possible to be accountable for the majority ... -

Scuba Physiological: Think You Know All About Scuba Medicine? Think again!
01 décembre 2017, HE Bruxelles BrabantLivre/Ouvrage ou monographie"This book makes it easy to understand the latest discoveries in diving research. You will enjoy reading about our current understanding of what happens to our bodies when we dive." JP Imbert: Decompression designer and technical diving pioneer "As a doctor with a fair history and understanding of diving medicine and diving physiology I found the book interesting. It's the sort of book I would ... -
ULTRASONOGRAPHIC ASSESSMENT OF NECK MUSCULAR SIZE AND RANGE OF MOTION IN RUGBY PLAYERS
01 février 2018, HE Bruxelles BrabantArticle scientifiqueBackground: World Rugby Union laws are constantly evolving towards stringent injury-prevention, particularly for contested scrums, since front row players are most at risk of cervical spine injuries. Recently, some countries have also introduced tailored training programs and minimum performance requirements for playing in the front row. Nevertheless, these approaches lack an objective assessment ... -

Effect Of Induced Relative Hypoxia On Reticulocyte Count In Oncologycal Abdominal Surgery: A Single-Centre, Controlled, Randomized Pilot Study.
04 avril 2018, HE Bruxelles BrabantArticle scientifiqueErythropoietin (EPO) stimulating agents are known as alternatives to transfusion. However, they expose patients to thrombosis and are expensive. A phenomenon, “the normobaric oxygen paradox” (NOP), has been described. A transient hyperoxia followed by a prolonged return to normoxia acts as an effective trigger for EPO production. The mechanism depends on free O2 radicals and on reduced gluthatione ... -
Variability in circulating gas emboli after a same scuba diving exposure
30 avril 2018, HE Bruxelles BrabantArticle scientifiquePURPOSE: A reduction in ambient pressure or decompression from scuba diving can result in ultrasound-detectable venous gas emboli (VGE). These environmental exposures carry a risk of decompression sickness (DCS) which is mitigated by adherence to decompression schedules; however, bubbles are routinely observed for dives well within these limits and significant inter-personal variability in DCS risk ... -
Tirofiban, a Glycoprotein IIb/IIIa Antagonist, Has a Protective Effect on Decompression Sickness in Rats: Is the Crosstalk Between Platelet and Leukocytes Essential?
11 juillet 2018, HE Bruxelles BrabantArticle scientifiqueIn its severest forms, decompression sickness (DCS) may extend systemically and/or induce severe neurological deficits, including paralysis or even death. It seems that the sterile and ischemic inflammatory phenomena are consecutive to the reaction of the bubbles with the organism and that the blood platelet activation plays a determinant role in the development of DCS. According to the hypotheses ... -
One-week cocoa flavanol intake increases prefrontal cortex oxygenation at rest and during moderate-intensity exercise in normoxia and hypoxia
12 juillet 2018, HE Bruxelles BrabantArticle scientifiqueDuring exercise in hypoxia, O2 delivery to brain and muscle is compromised, and oxidative stress is elicited. Cocoa flavanols (CF) have antioxidant capacities and can increase blood flow by stimulating endothelial function. We aimed to examine the effects of 7-day CF intake on oxidative stress, nitric oxide production, and tissue oxygenation in response to exercise in normobaric hypoxia (14.3% O2). ... -

Spirometry and oxidative stress after rebreather diving in warm water
05 août 2018, HE Bruxelles BrabantArticle scientifiqueIntroduction: Hyperbaric oxygen (HBO(2)) therapy and use of enriched air can result in oxidative injury affecting the brain, lungs and eyes. HBO(2) exposure during diving can lead to a decrease in respiratory parameters. However, the possible effects of acute exposure to oxygen-enriched diving on subsequent spirometric performance and oxidative state in humans have not been recently described recently. ... -
Hemoglobin and Erythropoietin After Commercial Saturation Diving
21 août 2018, HE Bruxelles BrabantArticle scientifiqueSaturation divers are exposed to elevated partial pressure of oxygen (ppO2) in their hyperbaric work environment. Experimental studies indicate that oxygen transport is altered, and we have previously reported a drop in hematocrit and extensive downregulation of genes involved in blood oxygen transport capacity after decompression from professional saturation diving. Here we investigate the initial ...
