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 ... -
Qu'est-ce qui va changer? - Capitre dans Coeur et Plongée
10 août 2017, HE Bruxelles BrabantLivre/Ouvrage ou monographieLe monde sous-marin est devenu accessible au plus grand nombre. Les méthodes de plongée se sont diversifiées, la population de plongeurs aussi... Mais la plongée demeure une activité à risques. Les pathologies cardiaques peuvent faire courir des dangers importants, non seulement au plongeur, mais aussi à tous ceux impliqués en cas d'assistance. Or, les données concernant les décès en plongée mettent ... -

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 ... -
Ultrasonographic Assessment of Neck Muscular Size and Range of Motion in Rugby Players
28 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.

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 ... -
Decreased Incidence of Pulmonary Barotrauma After Discontinuation of Emergency Free Ascent Training
22 août 2018, HE Bruxelles BrabantArticle scientifiqueINTRODUCTION: Because a significant association between training to perform emergency free ascent (EFA) and the occurrence of pulmonary barotrauma (PBT) was demonstrated in 2006, the Belgian Underwater Federation (BUF) decided to discontinue this procedure. An evaluation was needed 10 yr after the implementation of this change. METHODS: All medical records with a diagnosis of PBT that occurred in ... -

Commercial Divers' Subjective Evaluation of Saturation
30 janvier 2019, HE Bruxelles BrabantArticle scientifiqueCommercial saturation diving involves divers living and working in an enclosed atmosphere with elevated partial pressure of oxygen (ppO2) for weeks. The divers must acclimatize to these conditions during compression, and for up to 28 days until decompression is completed. During decompression, the ppO2 and ambient pressure are gradually decreased; then the divers must acclimatize again to breathing ... -
Simulated air dives induce superoxide, nitric oxide, peroxynitrite, and Ca 2+ alterations in endothelial cells
03 avril 2019, HE Bruxelles BrabantArticle scientifiqueHuman diving is known to induce endothelial dysfunction. The aim of this study was to decipher the mechanism of ROS production during diving through the measure of mitochondrial calcium concentration, peroxynitrite, NO°, and superoxide towards better understanding of dive-induced endothelial dysfunction. Air diving simulation using bovine arterial endothelial cells (compression rate 101 kPa/min to ...
