A review of nutritional recommendations for scuba divers Open
BACKGROUND: Scuba diving is an increasingly popular activity that involves the use of specialized equipment and compressed air to breathe underwater. Scuba divers are subject to the physiological consequences of being immersed in a high-pr…

Physiology of deep closed circuit rebreather mixed gas diving: vascular gas emboli and biological changes during a week-long liveaboard safari Open
Introduction: Diving decompression theory hypothesizes inflammatory processes as a source of micronuclei which could increase related risks. Therefore, we tested 10 healthy, male divers. They performed 6–8 dives with a maximum of two dives…

Physiology of Deep Closed-Circuit Rebreather (CCR) Mixed Gas Diving: Gas Emboli, Spirometry and Biological Changes during a Week-Long Liveaboard Safari Open
Diving decompression theory hypothesizes inflammatory processes as a source of micronuclei which could increase related risks. Therefore, we tested 10 healthy, male divers. They performed 6-8 dives with a maximum of two dives per day at de…

An open-source framework for synthetic post-dive Doppler ultrasound audio generation Open
Doppler ultrasound (DU) measurements are used to detect and evaluate venous gas emboli (VGE) formed after decompression. Automated methodologies for assessing VGE presence using signal processing have been developed on varying real-world d…

Analysis of Single- and Double-Stranded DNA Damage in Osteoblastic Cells after Hyperbaric Oxygen Exposure Open
(1) Background: Hyperbaric oxygen (HBO) exposure induces oxidative stress that may lead to DNA damage, which has been observed in human peripheral blood lymphocytes or non-human cells. Here, we investigated the impact of hyperbaric conditi…

The risk of decompression illness in breath-hold divers: a systematic review Open
Introduction: Breath-hold (BH) diving has known risks, for example drowning, pulmonary oedema of immersion and barotrauma. There is also the risk of decompression illness (DCI) from decompression sickness (DCS) and/or arterial gas embolism…

A survey of caustic cocktail events in rebreather divers Open
Introduction: Closed-circuit rebreathers (CCRs) are designed to be watertight. Ingressing water may react with carbon-dioxide absorbent in the CCR, which may produce alkaline soda with a pH of 12-14, popularly referred to by CCR divers as …

Comparison of Newer Hand-Held Ultrasound Devices for Post-Dive Venous gas Emboli Quantification to Standard Echocardiography Open
Decompression sickness (DCS) can result from the growth of bubbles in tissues and blood during or after a reduction in ambient pressure, for example in scuba divers, compressed air workers or astronauts. In scuba diving research, post-dive…

Health and wellbeing of recently active United States scuba divers Open
Introduction: This study aimed to describe recently active adult scuba divers in the United States (US) and compare their characteristics with other active adults. The research question was: do active scuba divers have different health and…

Incidence of cardiac arrhythmias and left ventricular hypertrophy in recreational scuba divers Open
Introduction: The aims of this study were to investigate the potential impact of age, sex and body mass index (BMI) upon the incidence of arrhythmias pre- and post- diving, and to identify the prevalence of left ventricular hypertrophy (LV…

Hyperoxia Alters Ultrastructure and Induces Apoptosis in Leukemia Cell Lines Open
Oxygenation conditions are crucial for growth and tumor progression. Recent data suggests a decrease in cancer cell proliferation occurring after exposure to normobaric hyperoxia. Those changes are associated with fractal dimension. The pu…

Decompression illness with hypovolemic shock and neurological failure symptoms after two risky dives: a case report Open
Hypovolemia is known to be a predisposing factor of decompression illness ( DCI ) while diving. The typical clinically impressive neurological symptoms of DCI may distract from other symptoms such as an incipient hypovolemic shock. We repo…

Effect of normobaric hyperoxia on leukemic cell lines in vitro Open
Aims and Objectives: The objective of this study was to evaluate the molecular mechanisms following normobaric hyperoxia on acute lymphoblastic leukemic cell lines in vitro through assessment of oxidative stress, DNA-fragmentation, mitocho…

From theory to bench confirmation or from bench to theory Open
In this commentary, the authors discuss two possible approaches in experimental studies. The first approach is to replicate an experimentation in order to confirm or not previously published results. The second one is more theoretical and …
