Sleep quality and duration are critical indicators of individual health. Traditional methods monitoring them either were limited to the application environment or resulted in discomfort. To overcome these existing limitations, we propose a noncontact sleep system placed under mattress, named SleepMatrix, provide users with comprehensive picture their real-time long-term health status. SleepMatr...

severity, HDM-specific IgE, and CD30 are significantly decreased with occlusive bed covers, however, there was not a statistically significant difference between the study populations. Additionally, HDM allergen in this study was not common and may not be an important factor in the disease process of this population. Future studies should include participants with both sensitization and signifi...

Background: Maintaining normothermia during porcine surgery is critical in ensuring subject welfare and recovery, reducing the risk of immune system compromise and surgical-site infection that can result from hypothermia. In humans, various methods of patient heating have been demonstrated to be useful, but less evaluation has been performed in techniques to prevent hypothermia perioperatively ...

Infants spend most of their time sleeping and are likely to be exposed to elevated concentrations of chemicals released from their crib mattresses. Small-scale chamber experiments were conducted to determine the area-specific emission rates (SERs) of volatile organic compounds (VOCs) in a collection of twenty new and used crib mattresses. All mattress samples were found to emit VOCs and the mea...

BACKGROUND After performing an aortotomy, there are a variety of techniques utilized for suture closure. There is no published data comparing the efficacy of various suture techniques. The goal of this study is to provide an ex-vivo quantitative assessment of resistance to leakage and dehiscence for three aortotomy closure techniques. MATERIALS AND METHODS An ex-vivo model was developed utili...

Background. Cardiopulmonary resuscitation (CPR) feedback devices are being increasingly used. However, current accelerometer-based devices overestimate chest displacement when CPR is performed on soft surfaces, which may lead to insufficient compression depth. Aim. To assess the performance of a new algorithm for measuring compression depth and rate based on two accelerometers in a simulated re...

abstract background: the cosmetic result of the surgical scar has long been considered by surgeons as an important factor for patient satisfaction. on the other hand, there has been an old teaching that perfect closure of contaminated wounds increases the rate of infection. we decided to look into this matter and see if this is a fact or a myth. methods: in this prospective randomized study con...
