Arterial Oxygen Desaturation Hinders Gamified Working Memory Performance.

Introduction: Hypoxia presents a physiological challenge to the Warfighters during military aviation and subterranean warfare operations by decreasing the supply of oxygen to the brain, which results in a reduced cognitive function depending on the magnitude and duration of hypoxic exposure. Moderate hypoxic exposures, fractions of inspired oxygen (FiO2) of 0.11 to 0.

Inclusive Research Environments for Deaf and Hard of Hearing English Speakers.

In recent years, an increasing number of deaf and hard of hearing (D/HH) undergraduates have chosen to study in STEM fields and pursue careers in research. Yet, very little research has been undertaken on the barriers and inclusive experiences often faced by D/HH undergraduates who prefer to use spoken English in research settings, instead of American Sign Language (ASL). To identify barriers and inclusive strategies, we studied six English speaking D/HH undergraduate students working in research laboratories with their eight hearing mentors, and their three hearing peers sharing their experiences.

Arterial oxygen desaturation during moderate hypoxia hinders sensorimotor performance.

Introduction: Moderate hypoxia may impact cognitive and sensorimotor performance prior to self-recognized impairments. Therefore, rapid and objective assessment tools to identify people at risk of impaired function during moderate hypoxia is needed.

Purpose: Test the hypothesis that reductions in arterial oxygen saturation during moderate normobaric hypoxia (FiO2 = 14%) decreases gamified sensorimotor performance as measured by alterations of motor acuity.

Cardiac arrest in a newborn: A case of pseudohypoaldosteronism.

Pseudohypoaldosteronism (PHA) is a rare disease that can cause life-threatening hyperkalemia, which could lead to cardiac arrest and death if not recognized and treated quickly. We report a case of a neonate who was diagnosed with PHA type 1 and found to have a novel variant gene mutation on the NR3C2 gene. A 5-day-old newborn presented in cardiac arrest with severe hyperkalemia, hyponatremia, and metabolic acidosis.

Gamified assessment of cognitive performance during moderate hypoxia.

Introduction: There is a need for rapid and objective assessment tools to identify people at risk of impaired cognitive function during hypoxia.

Purpose: To test the hypotheses that performance on gamified cognitive tests examining the cognitive domains of executive function (Gridshot), working memory (Capacity) and spatial tracking (Multitracker) will be reduced during normobaric exposure to moderate normobaric hypoxia.

Methods: Following three consecutive days of practice, twenty-one healthy adults (27 ± 5 y, 9 females) completed five 1-min rounds of the tablet-based games Gridshot, Capacity, and Multitracker (Statespace Labs, Inc.
