Real-time detection of basic physiological parameters such as blood pressure and heart rate is an important target in wearable smart devices for healthcare. Among these, the core body temperature is one of the most important basic medical indicators of fever, insomnia, fatigue, metabolic functionality, and depression. However, traditional wearable temperature sensors are based upon the measurement of skin temperature, which can vary dramatically from the true core body temperature. Here, we demonstrate a three-dimensional (3D) printed wearable "earable" smart device that is designed to be worn on the ear to track core body temperature from the tympanic membrane (i...

BACKGROUND: Brain death (BD) is a donor-associated risk factor that negatively affects transplantation outcome. The inflammation associated with BD appears to have a negative effect on organ quality. Complement activation, apoptosis, and pro-inflammatory cytokine and chemokine expression are significantly increased after BD. To better understand this process, we investigated plasma chemokine and cytokine levels for 8h after BD in a rodent model. METHODS: Thirteen healthy adult male Sprague Dawley rats were intubated and mechanically ventilated...

Intensive behavioral counseling interventions combined with nicotine replacement therapy have increased smoking abstinence rates in cardiac patients, but little is known about their feasibility when initiated upon hospital admission and continued post-discharge. The current study was an evaluation of the use, appreciation, and fidelity of two post-discharge counseling interventions designed for cardiac patients to quit smoking that differed in their delivery mode. In a controlled trial with cross-over randomization at the cardiac unit level, hospitalized smokers in eight cardiac units of eight Dutch hospitals were assigned either telephone counseling (n = 223) or nurse-administered face-to-face counseling (n = 157) using the Ask-Advise-Refer strategy...

BACKGROUND: Excessive adrenergic signaling may be harmful in sepsis. Using β-blockers to reduce sympathetic overactivity may modulate sepsis-induced cardiovascular, metabolic, immunologic, and coagulation alterations. Using a randomized ovine fecal peritonitis model, we investigated whether administration of a short-acting β-blocker, esmolol, could control tachycardia without deleterious effects on hemodynamics, renal perfusion, cerebral perfusion, cerebral metabolism, or outcome. METHODS: After induction of fecal peritonitis, 14 anesthetized, mechanically ventilated, and hemodynamically monitored adult female sheep were randomly assigned to receive a continuous intravenous infusion of esmolol to control heart rate between 80 and 100 bpm (n = 7) or a saline infusion (control group, n = 7)...

Adaptive changes in oxygenation and hemodynamics are evaluated during pediatric laparoscopy. The children underwent laparoscopy (LAP Group, n=20) or open surgery (Open Group, n=10). Regional cerebral (rScO2) and peripheral oxygen saturation (SpO2), heart rate (HR), diastolic (DP) and systolic pressure (SP) were monitored at different intervals: basal (T0); anesthesia induction (T1); CO2PP insufflation (T2); surgery (T3); CO2PP cessation (T4); before extubation (T5). At T1, in both the LAP and Open groups significant changes in rScO2, DP and SP were recorded compared with T0; a decrease in SatO2 was also observed at T5...

The brain is a central component of cognitive and physical human performance. Measures including functional brain activation, cerebral perfusion, cerebral oxygenation, evoked electrical responses, and resting hemodynamic and electrical activity are all related to, or can predict health status or performance decrements. However, measuring brain physiology typically requires large, stationary machines that are not suitable for mobile or self-monitoring. Moreover, when individuals are ambulatory, systemic physiological fluctuations-e...

REVIEW
William T Abraham, Leor Perl
Rates of heart failure hospitalization remain unacceptably high. Such hospitalizations are associated with substantial patient, caregiver, and economic costs. Randomized controlled trials of noninvasive telemedical systems have failed to demonstrate reduced rates of hospitalization. The failure of these technologies may be due to the limitations of the signals measured. Intracardiac and pulmonary artery pressure-guided management has become a focus of hospitalization reduction in heart failure. Early studies using implantable hemodynamic monitors demonstrated the potential of pressure-based heart failure management, whereas subsequent studies confirmed the clinical utility of this approach...

The regular monitoring of athletes is important to fine-tune training and detect early symptoms of overreaching. Therefore the aim of this study was to determine if a noninvasive submaximal running test could reflect a state of overreaching. 14 trained runners completed a noninvasive Lamberts Submaximal Running Test, one week before and 2 days after finishing an ultramarathon, and delayed onset of muscle soreness and the daily analysis of life demands for athletes questionnaire were also captured. After the ultramarathon, submaximal heart rate was lower at 70% (-3 beats) and 85% of peak treadmill running speed (P<0...
