![]() Tine Brink Henriksen, both clinicians and researchers from the Neonatal Intensive Care Unit at Aarhus University Hospital in Denmark. Rubens recently travelled to Denmark to collaborate with researchers on the next steps that will follow this finding. The link between inner ear damage and carbon dioxide could be key to understanding why seemingly healthy babies, who might have ear damage that's not readily apparent, succumb to SIDS. "This was in addition to the finding that inner ear damage in its own right also suppresses those protective arousal movements." "We observed that a lack of oxygen is the stimulus for the survival movements, and carbon dioxide suppresses that protective response," Rubens said. ![]() This was the case under natural sleep conditions as well as light anesthesia. They identified a novel and unexpected finding: Carbon dioxide was not the stimulus for arousal movements during sleep as one would expect. Nino Ramirez, director of the Center for Integrative Brain Research at Seattle Children's Research Institute, studied combinations of low oxygen and rising carbon dioxide to examine how different levels of the gases impact mice without inner ear damage versus mice with inner ear damage. In the study, Rubens looked at the balance of oxygen and carbon dioxide in the sleeping environment of mice. "Research takes time and funding, and we hope that by telling our story that others might be inspired to support the research as well."Ī fine balance of oxygen and carbon dioxide Rubens' ear off and learn whatever she could about this research," Dore said. "If my mom was alive, I know she would talk Dr. The foundation supports charitable causes the couple championed over the years, including SIDS research. Dore Foundation as continuing legacy to give back to the community. Now, when first responders enter a home with a baby, they look for unsafe conditions like sleeping position or a crib with blankets and toys, and those responders can offer safety education for families right there." "My dad developed legislation that raised awareness about SIDS as a public health issue. "She and my dad, Fred Dore Sr., wanted to prevent this from happening to other families," he said. She also began to counsel other families who had lost babies. His mother, Mary Dore, began to talk to doctors at Seattle Children's about what might have happened and was determined to find a cause. "I remember how distraught my mother was to find that the healthy baby she'd put to sleep in her crib had died." ![]() "I was 3 years old and I recall the fireman coming in to see what had happened," Dore said. Fred Dore, an internal medicine physician in Bremerton, Washington, is energized by research to crack the medical mystery of SIDS, and for good reason: He recalls the day his little sister, Christine, died of SIDS. Research support from a doctor who lost sister to SIDSĭr. About 2,000 babies born in the United States die each year from SIDS. According to the Centers for Disease Control, SIDS is one of the leading causes of death in infants 1 to 12 months old. ![]() SIDS is defined as the sudden death of an infant that cannot be explained by any other cause after a thorough autopsy, examination of the death scene and review of the clinical history. We want to fine tune this discovery and study the connection to carbon dioxide in more detail." "We found that exposure to increasing levels of carbon dioxide and inner ear damage in mice resulted in a lack of movement toward safety and fresh air during sleep. "This is potentially an important breakthrough in understanding the biological underpinnings of what may be causing SIDS," Rubens said. ![]()
