LieRHRV system for remote lie detection using heart rate variability parameters.
Sci Rep
December 2024
Laboratory of Bioelectric and Bioenergetic Systems, Faculty of Biomedical Engineering, Technion-Israel Institute of Technology, Haifa, Israel.
The standard polygraph, or lie detector, is limited by its reliance on average heart rate, subjective examiner interpretation, and the need for direct subject contact. Remote photoplethysmography (rPPG) offers a promising contactless alternative, by using facial videos to extract heart rate variability (HRV). We introduce "LieRHRV," a remote lie detection algorithm based solely on extracted HRV parameters.

Background Investigating changes in brain electroencephalogram activity during blood pressure measurement in sitting and standing positions is clinically significant for understanding the neural correlates of postural changes, which may affect cerebral perfusion and autonomic regulation. Shifts in blood pressure can influence visual cortical activity, potentially altering cognitive and sensory processing. This research holds clinical relevance in evaluating disorders like orthostatic hypotension and syncope, where postural changes compromise cerebral blood flow.

Article Synopsis
- This study investigated the relationship between sleep apnea syndrome (SAS) and the dosage/timing of opioid substitution treatments (OST) in patients using methadone or buprenorphine for opioid use disorder.
- It included a retrospective analysis of adult patients who received these treatments over several years, assessing their apnea-hypopnea index (AHI) alongside treatment data.
- The findings indicated that higher doses of methadone, particularly taken in the evening, were linked to more severe SAS, while no significant association was found between buprenorphine doses and AHI, suggesting buprenorphine might be a better alternative for patients with SAS.

Background And Objectives: Lance-Adams syndrome (LAS), or chronic posthypoxic myoclonus, is a long-term disabling neurologic disorder occurring in survivors of anoxia. The cortical or subcortical origin of this myoclonus is unclear. We aimed to identify the neuroanatomical origin of myoclonus in LAS.

Obstructive sleep apnea hypopnea syndrome (OSA) in pregnant women is an under-diagnosed but common condition, due to the numerous physiological changes favoring upper airway collapse. Risk factors such as significant weight gain during the 1st trimester, maternal age and parity should be systematically investigated. Diagnosis is made by sleep recording.
