Variation of Cognitive Function During a Short Stay at Hypobaric Hypoxia Chamber (Altitude: 3842 M)
De Bels D, Pierrakos C, Bruneteau A, Reul F, Crevecoeur Q, Marrone N, Vissenaeken D, Borgers G, Balestra C, Honore PM & Theunissen S.

Objective To observe the effects of a fast-acute ascent to high altitude on brain cognitive function and transcranial doppler parameters in order to understand the physiological countermeasures of hypoxia. Methods 17 high-altitude-naïve male subjects (mean age was 26.3 ± 8.1 years) participated in the study. We measured Critical Flicker Fusion Frequency (CFFF), blood oxygen saturation, Psychology Experiment Building (PEBL) including three tests (Modified Math Processing Task, Perceptual Vigilance Task, and Time Estimation Task), as well as Cerebral Blood Flow index (CBFi), mean cerebral artery Systolic and diastolic velocities, Cerebral Pulsatility index (CPi), and heart Rate. All were measured at sea level, at least 1 h after arrival at the hypobaric hypoxia equivalent of 3842 m and 1 h after return to sea level.

Safety of recreatiional scuba diving in type 1 diabetic patients. The Deep Monitoring programme
Bonomo M., Cairoli R., Verde G., Morelli L., Moreo A., Delle Grottaglie M., Brambilla M.C., Meneghini E., Aghemo P., Corigliano G., Marroni A.

Aim: To verify whether, with thorough practical and theoretical training, well-controlled, non-complicated diabetic patients can safely go diving underwater with no additional medical or metabolic risks. Methods: Twelve diabetic patients participated in the study after undergoing training focused on their diabetic status. Two dives per day were scheduled during two five-day stays on the island of Ventotene (Italy). Capillary blood glucose (BG) was checked at 60, 30 and 10 minutes before diving, and corrective measures adopted if necessary, based on BG absolute levels and dynamics. A device for continuous subcutaneous glucose monitoring (CGM), expressly modified for the purpose, was worn during dives.

Recreational diving today: decompression habits, DAN Europe database insights
Balestra C, Cialoni D, Buzzacott P, Hemelryck W, Papadopoulou V, Pieri M & Marroni A.

Compared with other sports, SCUBA diving remains a relatively safe activity but precisely defining risk is important. Diving databases such as the Diving Safety Laboratory (DSL) collection by Divers Alert Network (DAN) Europe can provide new insights into the causes of diving accidents, including decompression sickness (DCS) incidence with respect to the dive profile. Data from the DSL shows that in the recreational setting diving with a dive computer may be used by as many as 95% of divers. This points to the need of validating these tools with respect to DCS incidence, a difficult task.

Patent Foramen Ovale (PFO), personality traits, and iterative decompression sickness. Retrospective analysis of 209 cases
Lafère P., Balestra C., Caers D., Germonpré P.

Introduction: 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).

Doppler ultrasound dataset for the development of automatic emboli detection algorithms
Paola Pierleoni, Marco Mercuri Alberto Belli, Massimo Pieri, Alessandro Marroni, Lorenzo Palma

The article describes a dataset of doppler ultrasound audio tracks taken on a sample of 30 divers according to the acquisition protocol defined by the Divers Alert Network. The audio tracks are accompanied by a medical evaluation for the decompression sickness risk according to the Spencer's scale levels. During the acquisition campaign, each diver in the post-dive phase was subjected to a double doppler ultrasound examination of approximately 45 seconds each one in the precordial area using a Huntleigh FD1 Fetal doppler probe. The two measurements were separated by a time of 8-10 seconds necessary for carrying out specific physical exercises designed to free the bubbles trapped in the tissues.
