Web-Based, Interactive, Interest-Based Negotiation Training for Managing Conflict in Isolated Environments: Opportunistic Study With an e-Survey.

Background: Effective negotiation in relationships is critical for successful long-duration space missions; inadequate conflict resolution has shown serious consequences. Less desirable forms of negotiation, including positional bargaining (eg, negotiating prices), can exacerbate conflicts. Traditional positional bargaining may work for simple, low-stakes transactions but does not prioritize ongoing relationships.

International Multicenter Registry for Hyperbaric Oxygen Therapy: Results through June 2021.

Introduction: The International Multicenter Registry for Hyperbaric Oxygen Therapy (International Report Registered Identifier DERR1-10.2196/18857) was established in 2011 to capture outcomes and complications data for both Undersea and Hyperbaric Medical Society (UHMS) approved and selected unapproved hyperbaric oxygen (HBO2) therapy indications.

Methods: A Research Electronic Data Capture (REDCap) template was designed and distributed to all participating centers for prospective data collection.

Test-Retest repeatability of automated threshold audiometry in Nicaraguan schoolchildren.

Objective: Automated threshold audiometry (ATA) could increase access to paediatric hearing assessment in low- and middle-income countries, but few studies have evaluated test-retest repeatability of ATA in children. This study aims to analyse test-retest repeatability of ATA and to identify factors that affect the reliability of this method.

Design: ATA was performed twice in a cohort of Nicaraguan schoolchildren.

Use of a Self-guided Computerized Cognitive Behavioral Tool During COVID-19: Evaluation Study.

Background: Internet-based programs can help provide accessible and inexpensive behavioral health care to those in need; however, the evaluation of these interventions has been mostly limited to controlled trials. Data regarding patterns of use and effectiveness of self-referred, open-access online interventions are lacking. We evaluated an online-based treatment designed to address stress, depression, and conflict management, the Dartmouth PATH Program, in a freely available and self-guided format during the COVID-19 pandemic.

Autonomous Psychological Support for Isolation and Confinement.

Isolated and confined environments (ICEs), such as spaceflight, are challenging psychologically. We have been evaluating self-directed tools to sustain and improve psychological well-being in these settings. The Expedition Application for Peak Psychological Performance (Expedition-APPP) is an interactive media-based set of self-directed tools that address conflict resolution, stress management, and depression treatment.

Development of an International, Multicenter, Hyperbaric Oxygen Treatment Registry and Research Consortium: Protocol for Outcome Data Collection and Analysis.

Background: Hyperbaric oxygen (HBO)-oxygen at pressures higher than atmospheric-is approved for 14 indications by the Undersea and Hyperbaric Medical Society. HBO's main effect is to increase oxygen content in plasma and body tissues, which can counteract hypoxia or ischemia. Laboratory studies show that HBO has effects beyond relieving hypoxia (eg, promoting angiogenesis in irradiated tissue, anti-inflammatory effects, radiosensitization of tumors, hypoxia preconditioning, and fungal growth inhibition) and has potential to treat conditions such as inflammatory bowel disease and pyoderma gangrenosum.

Portable Autorefractors for Detecting Axial Length Changes in Space.

Introduction: We evaluated the reproducibility of two portable, self-administered autorefractors (Netra and SVOne Pro) to assess the time course of visual changes on the ISS.

Methods: We measured cycloplegic refractive error at 5 visits at least a week apart in 13 subjects (6 women, 7 men, 30 ± 9 yr) using both devices seated and also prone with lower body positive pressure (LBPP) applied. Axial length was measured with an optical biometer.

Relaxation with Immersive Natural Scenes Presented Using Virtual Reality.

Introduction: Virtual reality (VR) can provide exposure to nature for those living in isolated confined environments. We evaluated VR-presented natural settings for reducing stress and improving mood.

Methods: There were 18 participants (9 men, 9 women), ages 32 ± 12 yr, who viewed three 15-min 360° scenes (an indoor control, rural Ireland, and remote beaches).
