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 ... -
Nitric oxide-related endothelial changes in breath-hold and scuba divers
01 mars 2013, ; Guerrero, François; Sponciello, Nicholas; Cialoni, Danilo; Pieri, Massimo; ; Obeid, Georges; Tillmans, Frauke; Papadopoulou, Virginie; ; Marroni, Alessandro; De Bels, David; BALESTRA, Costantino, HE Bruxelles Brabant
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 ... -
Dark chocolate reduces endothelial dysfunction after successive breath-hold dives in cool water
16 septembre 2013, ; Schumacker, Julie; Guerrero, François; Tillmans, Frauke; ; Lambrechts, Kate; Mazur, Alexandra; Pieri, Massimo; ; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiqueObjective: The aim of this study is to observe the effects of dark chocolate on endothelial function after a series of successive apnea dives in non-thermoneutral water. Methods: Twenty breath-hold divers were divided into two groups: a control group (8 males and 2 females) and a chocolate group (9 males and 1 female). The control group was asked to perform a series of dives to 20 m adding up to ... -
Pre-dive Whole-Body Vibration Better Reduces Decompression-Induced Vascular Gas Emboli than Oxygenation or a Combination of Both
17 février 2015, Cavalade, Maxence; Papadopoulou, Virginie; ; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiquePurpose: The purpose of this study was (1) to further explore the heart rate dynamics and assess a potential cardiovascular risk in response to 4000 m jumps in experienced skydivers; (2) to assess whether there is an impact of such jumps on skydivers' cortical arousal or not, which may impact their decision making processes. Method: 18 experienced skydivers performed successive jumps from a plane ... -
Venous gas emboli are involved in post-dive macro, but not microvascular dysfunction
21 janvier 2017, ; BALESTRA, Costantino; Theron, Michaël; Henckes, Anne; Galinat, Hubert; Mignant, Fanny; Belhomme, Marc; Pontier, Jean-Michel; Guerrero, François, HE Bruxelles Brabant
Article scientifiquePurpose: Previous studies have shown vascular dysfunction of main conductance arteries and microvessels after diving. We aim to evaluate the impact of bubble formation on vascular function and haemostasis. To achieve this, we used a vibration preconditioning to influence bubble levels without changing any other parameters linked to the dive. Methods: Twentty-six divers were randomly assigned to ... -
Spirometry and oxidative stress after rebreather diving in warm water
05 août 2018, Bosco, Gerardo; Quartesan, Silvia; Mrakic-Sposta, Simona; Moretti, Sarah; BALESTRA, Costantino; Rubini, Alessandro, HE Bruxelles Brabant
Article 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. ... -
Pre-dive Whole-Body Vibration Better Reduces Decompression-Induced Vascular Gas Emboli than Oxygenation or a Combination of Both
30 novembre 2016, BALESTRA, Costantino; ; Papadopoulou, Virginie; Le Mener, Cédric; ; Guerrero, François; Lafère, Pierre, HE Bruxelles Brabant
Article scientifiquePurpose: Since non-provocative dive profiles are no guarantor of protection against decompression sickness, novel means including pre-dive "preconditioning" interventions, are proposed for its prevention. This study investigated and compared the effect of pre-dive oxygenation, pre-dive whole body vibration or a combination of both on post-dive bubble formation. Methods: Six healthy volunteers performed ... -

12 avril 2017, Brebek, Anne-Kathrin; Deussen, Andreas; Schmitz-Peiffer, 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 ... -

Ultrasonographic Assessment of Neck Muscular Size and Range of Motion in Rugby Players
28 février 2018, ; Calistri, Josselin; Dugardeyn, Christian; BALESTRA, Costantino, HE Bruxelles Brabant
Article 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 ... -
Critical Flicker Fusion Frequency: A Marker of Cerebral Arousal During Modified Gravitational Conditions Related to Parabolic Flights
02 octobre 2018, BALESTRA, Costantino; Machado, Marie-Laure; Theunissen, Sigrid; ; Cialoni, Danilo; Clot, Christian; Besnard, Stépane; Kammacher, Laura; Delzenne, Julie; ; Lafère, Pierre, HE Bruxelles Brabant
Article scientifiqueIn situ evaluation of human brain performance and arousal remains challenging during operational circumstances, hence the need for a rapid, reliable and reproducible tool. Here we hypothesized that the Critical flicker fusion frequency (CFFF) reflecting/requiring visual integration, visuo-motor skills and decision-taking process might be a powerful, fast and simple tool in modified gravity environments. ...
