McGrath® versus Macintosh laryngoscopes on hemodynamic response to intubation in elderly patients: a randomized clinical trial.

Introduction: laryngoscopy and tracheal intubation induce catecholaminergic release. Our study aimed to evaluate the hemodynamic impact of orotracheal intubation by McGrath® compared to the Macintosh laryngoscope in the elderly.

Methods: we conducted a prospective randomized clinical trial that included elderly patients proposed for a scheduled surgery under general anesthesia with orotracheal intubation and divided into 2 groups: patients who were intubated using the McGrath® (group V) and patients who were intubated using the Macintosh direct laryngoscope (group M).

Portable impedance-sensing device for microorganism characterization in the field.

A variety of biosensors have been proposed to quickly detect and measure the properties of individual microorganisms among heterogeneous populations, but challenges related to cost, portability, stability, sensitivity, and power consumption limit their applicability. This study proposes a portable microfluidic device based on impedance flow-cytometry and electrical impedance spectroscopy that can detect and quantify the size of microparticles larger than 45 µm, such as algae and microplastics. The system is low cost ($300), portable (5 cm [Formula: see text] 5 cm), low-power (1.

Recent Advances in CMOS Electrochemical Biosensor Design for Microbial Monitoring: Review and Design Methodology.

Rapid, high-sensitivity, and real-time characterization of microorganisms plays a significant role in several areas, including clinical diagnosis, human healthcare, early detection of outbreaks, and the protection of living beings. Integrating microbiology and electrical engineering promises the development of low-cost, miniaturized, autonomous, and high-sensitivity sensors to quantify and characterize bacterial strains at various concentrations. Electrochemical-based biosensors are receiving particular attention in microbiological applications among the different biosensing devices.
