Hypoxemia due to sleep apnea is associated with risk of lung cancer reoccurrence
Study is the first to link sleep apnea-induced hypoxemia and lung cancer reoccurrence
2024-06-04
(Press-News.org) DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting is the first to find that episodic hypoxemia and hypoxic burden related to obstructive sleep apnea are associated with the risk of accelerated lung cancer reoccurrence.
Results show that a 4% oxygen desaturation index of more than 15 and time spent in desaturation events were risk factors for cancer reappearance in less than two years. Measures of hypoxic burden such as time spent below 89% oxygen saturation, average oxygen saturation value below 89%, and single nadir oxygen levels, showed a similar association. After adjustment for potential confounders, average oxygen saturation below 89% and single minimum oxygen level remained strongly correlated with accelerated cancer reoccurrence.
“We were suspecting that we would find a positive association between measures of intermittent hypoxemia and lung cancer reoccurrence; nonetheless, we never expected to see such a strong signal,” said lead author Dr. Fernando Figueroa Rodriguez, sleep medicine fellow at the Mayo Clinic in the division of pulmonary, critical care, and sleep medicine in Rochester, Minnesota. “This caught us by surprise; but at the same time, this keeps us encouraged and eager to produce more data.”
The study involved a retrospective record review of 403 adult patients from January 2016 to September 2023. They had a median age of 74 years, and 52% were female. The patients had a history of non-small cell lung cancer and received an overnight oximetry study within three years prior to undergoing curative malignancy treatment. During the study period, 68 patients (22%) had lung cancer reoccurrence, with a median time period of 19 months.
Figueroa Rodriguez noted that a new study with an increased sample size has been initiated for the performance of additional analyses to better understand this relationship. Similarly, researchers at the Mayo Clinic are evaluating the impact of CPAP therapy for sleep apnea on cancer outcomes.
“At this time we have not finalized these next steps; nevertheless, we have a fantastic team working on the necessary requirements to have this data ready soon,” said Figueroa Rodriguez.
The research abstract was published recently in an online supplement of the journal Sleep and will be presented Tuesday, June 4, during SLEEP 2024 in Houston. SLEEP is the annual meeting of the Associated Professional Sleep Societies, a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society.

DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting found that healthy sleep has a positive impact on gratitude, resilience and flourishing in adults.
Results show that subjective sleepiness and mood disturbances improved with earlier bedtimes that extended sleep by an average of 46 minutes per night and worsened with later bedtimes that reduced nightly sleep by an average of 37 minutes. Measures of flourishing, resilience and gratitude significantly improved across the week with sleep extension and significantly worsened with sleep restriction. Sleep-extended ...

DARIEN, IL – A new study to be presented at the SLEEP 2024 annual meeting offers a framework for an objective, non-invasive and zero-effort sleep monitoring system utilizing smart thermostats equipped with motion sensors.
Results show that smart thermostats identified three distinct sleep quality clusters, with clear variations in sleep duration, disturbances and efficiency. Comparative analysis underscored the heterogeneity in sleep quality, highlighting the potential of smart devices and NextGen IoT data sources in identifying sleep patterns and contributing to sleep research ...

Ever wondered how your brain decides when to act? Initiating actions with a specific goal in mind is a complex process. Previous research has identified certain parts of the brain and chemical signals involved. However, it remains unclear what information these signals convey and how they spark initiative.
Recent research reported in Neurophotonics dives into this mystery by investigating how mice time their actions in pursuit of rewards, exploring the role of a specific brain pathway called the mesocortical pathway, in the context of self-initiated ...

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by elevated levels of inattention, impulsivity, and hyperactivity that can impair academic and social functioning. ADHD is also associated with increased levels of parenting stress, less effective parenting practices, and can disrupt the parent-child relationship. The importance of support for parents of children with ADHD is widely acknowledged in Japan, but specialized parent training programs targeting ADHD have not been available.
However, a new program developed at the Okinawa Institute of Science and Technology (OIST) aims to reduce the strain on families ...
