01 juin 2015, HE Bruxelles BrabantArticle scientifiqueCet article a pour objectif de décrire un processus de recherche engagé sur la formation pratique d’éducateurs sociaux en Belgique francophone dans le cadre d’une association dénommée Form’Educ. Cela se passe dans un groupe de huit Hautes-Ecoles engagées ensemble dans un projet de recherche pendant cinq ans (2011-2015) dans le but d'échanger leurs pratiques de formation concernant la formation ... -
Relationships between plasma lipids, proteins, surface tension and post-dive bubbles
13 février 2015, Schellaert, Nicolas; Rolzoznik, Miroslav; BALESTRA, Costantino
, HE Bruxelles Brabant
Article scientifiqueDecompression sickness (DCS) in divers is caused by bubbles of inert gas. When DCS occurs, most bubbles can be found in the venous circulation: venous gas emboli (VGE). Bubbles are thought to be stabilized by low molecular weight surfactant reducing the plasma-air surface tension (γ). Proteins may play a role as well. We studied the interrelations between these substances, γ and VGE, measured before ... -
Diving deeper into SCUBA Science
Livre/Ouvrage ou monographieThe editors of and authors of this book are a cadre of scientists and physicians with broad experience and knowledge of diving physiology and decompression theory. As is often the case, it requires a group effort to succeed in advancing practical knowledge. The colloquialism "the whole is greater than the sum of its parts" is often true and the PHYPODE Reasearch Group epitomizes this concept. By ... -
Do Environmental Conditions Contribute to Narcosis Onset and Symptom Severity?
14 octobre 2016, HE Bruxelles BrabantArticle scientifiqueAlthough many factors contributing to inert gas narcosis onset and severity have been put forward, the available evidence is not particularly strong. Using objective criteria, we have assessed brain impairment associated with narcosis under various environmental diving conditions. 40 volunteers performed a no-decompression dive (33 m for 20 min) either in a dry chamber, a pool or open sea. They were ... -
Effects of oxygen-enriched air on cognitive performance during SCUBA-diving - an open-water study
12 avril 2017, Brebeck, Anne-Kathrin; Deussen, Andreas; Schmitz-Pfeiffer, Henning; Range, Ursula; BALESTRA, Costantino; Cleveland, Sinclair; Schipke, Jochen, HE Bruxelles Brabant
Article scientifiqueBackround: Nitrogen narcosis impairs cognitive function, a fact relevant during SCUBA-diving. Oxygen-enriched air (nitrox) became popular in recreational diving, while evidence of its advantages over air is limited. AIM: Compare effects of nitrox28 and air on two psychometric tests. METHODS: In this prospective, double-blind, open-water study, 108 advanced divers (38 females) were randomized to an ... -
Evidence of Heritable Determinants of Decompression Sickness in Rats
22 juillet 2017, Lautridou, Jacky; Buzzacott, Peter; Belhomme, Marc; Dugrenot, Emmanuel; Lafère, Pierre; BALESTRA, Costantino; Guerrero, François, HE Bruxelles Brabant
Article 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 ... -
Dive Risk Factors, Gas Bubble Formation, and Decompression Illness in Recreational SCUBA Diving: Analysis of DAN Europe DSL Data Base
10 mai 2017, Cialoni, Danilo; Pieri, Massimo; BALESTRA, Costantino; Marroni, Alessandro, HE Bruxelles Brabant
Article 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, ... -
Preconditioning to Reduce Decompression Stress in Scuba Divers
Article scientifiqueBACKGROUND: Using ultrasound imaging, vascular gas emboli (VGE) are observed after asymptomatic scuba dives and are considered a key element in the potential development of decompression sickness (DCS). Diving is also accompanied with vascular dysfunction, as measured by flow-mediated dilation (FMD). Previous studies showed significant intersubject variability to VGE for the same diving exposure and ... -
Correlation between Patent Foramen Ovale, cerebral “lesions” and neuropsychometric testing in experienced sports divers: does diving damage the brain?
Article scientifiqueSCUBA diving exposes divers to decompression sickness (DCS). There has been considerable debate whether divers with a Patent Foramen Ovale of the heart have a higher risk of DCS because of the possible right-to-left shunt of venous decompression bubbles into the arterial circulation. Symptomatic neurological DCS has been shown to cause permanent damage to brain and spinal cord tissue; it has been ... -
Objective vs. Subjective Evaluation of Cognitive Performance During 0.4-MPa Dives Breathing Air or Nitrox
19 avril 2017, ; BALESTRA, Costantino; Hemelryck, Walter; Buzzacott, Peter; Lafère, Pierre, HE Bruxelles Brabant
Article 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 ... -
Patent Foramen Ovale (PFO), Personality Traits, and Iterative Decompression Sickness. Retrospective Analysis of 209 Cases
Article 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 ... -

The effect of pre-dive ingestion of dark chocolate on endothelial function after a scuba dive
Article scientifiqueObjective: The aim of the study was to observe the effects of dark chocolate on endothelial function after scuba diving. Methods: Forty-two male scuba divers were divided into two groups: a control (n=21) and a chocolate group (n=21). They performed a 33-metres deep scuba-air dive for 20 minutes in a diving pool (Nemo 33, Brussels). Water temperature was 33⁰C. The chocolate group ingested 30 g ... -

Article scientifiqueObjective: Scuba and breath-hold divers are compared to investigate whether endothelial response changes are similar despite different exposure(s) to hyperoxia. Design: 14 divers (nine scuba and five breath-holding) performed either one scuba dive (25m/25 minutes) or successive breath-hold dives at a depth of 20 meters, adding up to 25 minutes of immersion time in a diving pool. Flow-mediated ... -
