Effects of ultra-early stage hyperbaric oxygenation on the hind limb bone mineral density in rats after complete spinal cord transection.
To study the effects of ultra-early stage hyperbaric oxygenation on the hind limb bone mineral density in rats after complete spinal cord transection. ⋯ Ultra-early stage hyperbaric oxygenation alleviates the hind limb bone loss in femur bone in rats following complete spinal cord transection.

Randomized Controlled TrialHyperbaric side effects in a traumatic brain injury randomized clinical trial.
To catalog the side effects of 2.4 atmospheres absolute (atm abs) hyperbaric oxygen (HBO2) vs. sham on post-concussion symptoms in military service members with combat-related, mild traumatic brain injury (TBI). ⋯ This study demonstrated no major adverse events, such as pulmonary barotraumas, pulmonary edema or seizure. Given the infrequent, mild side effect profile, the authors feel the study demonstrated that hyperbaric oxygen therapy (HBO2T) was safe at a relatively high treatment pressure in TBI subjects, and these data can be used to evaluate the risk/ benefit calculation when deciding to utilize HBO2T for treatment of various diseases in the TBI population.

Hyperbaric oxygen therapy decreases blood pressure in patients with chronic wounds.
A single session of hyperbaric oxygen therapy (HBO2T) is known to act on the parasympathetic system and also increase the production of reactive oxygen species. However, the impact of a treatment series consisting of 20 to 40 sessions on blood pressure (BP) remains unknown. Thus, the current study aimed to assess the effect of this type of treatment in patients administered HBO2T as an adjunct therapy for wound healing. ⋯ In patients with chronic wounds requiring HBO2T, successive HBO2T treatments affect HR and SBP measurements. However, further prospective clinical investigations are required to evaluate the prolonged effects of HBO2T.

Randomized Controlled TrialHyperbaric oxygen for post-concussion syndrome: design of Department of Defense clinical trials.
The current wars in the Middle East have resulted in between 10-20% of U. S. service members with mild traumatic brain injury (mTBI). While anecdotal reports have associated hyperbaric oxygen (HBO2) with improved outcomes after mTBI, controlled research is lacking. ⋯ Compression pressures will range from 1.2 atm abs (sham) to 2.4 atm abs, and oxygen concentration will range from room air (sham and control) to 100%. Outcomes measures include both subjective and objective measures performed at baseline, at exposure completion, and at three to 12 months' follow-up. This integrated program of clinical trials investigating the efficacy of HBO2 in service members with persistent symptoms following mTBI exposure will be important to define practice guidelines and, if needed, for the development of definitive clinical trials in this population.

Case ReportsPrevalence of acute respiratory symptoms in breath-hold divers.
After repetitive deep dives, breath-hold divers are often affected by a syndrome characterized by typical symptoms such as cough, sensation of chest constriction, blood-striated expectorate (hemoptysis) and, rarely, an overt acute pulmonary edema syndrome, often together with various degrees of dyspnea. The aim of this work is an epidemiological investigation to evaluate the prevalence of acute respiratory symptoms (ARS) in breath-hold divers (BHDs) in practicing breath-hold diving. ⋯ Our data show that this is a common condition among experienced BHDs. In our opinion, this is particularly interesting for the free-diving community.
