Breaking the habit: isolating nicotine-degrading bacteria in undergraduate microbiology teaching labs.

Nicotine is a major alkaloid in tobacco plants and an addictive component of tobacco products. Some bacteria grow on tobacco plants and have evolved the ability to metabolize nicotine. As part of our microbiology teaching lab, we used minimal media with nicotine as the sole carbon source to isolate nicotine-degrading bacteria from tobacco leaves and commercial tobacco products.

Higher Prehospital Blood Glucose Levels Associated With Return of Spontaneous Circulation in Out-of-Hospital Non-traumatic Cardiac Arrests.

Objective: Cardiac arrest leads to an array of metabolic disturbances. We aimed to investigate the association between prehospital blood glucose levels (BGLs) and rates of return of spontaneous circulation (ROSC) in non-traumatic out-of-hospital cardiac arrests (OHCAs).

Methods: A retrospective analysis of adult non-traumatic OHCAs within Kalamazoo County, MI, from January 2018 to May 2020 using the Michigan Emergency Medical Services Information System database was performed.

Teaching Cardiopulmonary Resuscitation to Later Elementary School Students.

Study Objective: Bystander cardiopulmonary resuscitation (CPR) rates remain low in the United States. Training children is a proposed method to increase this rate, but data on the compression efficacy of US elementary school-aged children are scarce. We hypothesized that fourth and fifth graders could learn how to respond to cardiac arrests and provide effective chest compressions.

Emergency medical services Milestones 2.0: What has changed?

Background: Since 2015, development of competencies by emergency medical services (EMS) fellows have been evaluated using the EMS Milestones 1.0 developed by a working group consisting of relevant stakeholders convened by the Accreditation Council for Graduate Medical Education (ACGME). Feedback from users and data collected from the milestones assessments in the interim indicated a need for revision of the original milestones.

Retrospective Comparison of Prehospital Sustained Return of Spontaneous Circulation (ROSC) Rates Within a Single Basic Life Support Jurisdiction Using Manual vs Lund University Cardiac Assist System (LUCAS-2) Mechanical Cardiopulmonary Resuscitation.

Objective Several studies have examined the impact of mechanical cardiopulmonary resuscitation (CPR) devices among multi-jurisdictional emergency medical services (EMS) systems; however, the variability across such systems can inject bias and confounding variables. We focused our investigation on the effect of introducing the Lund University Cardiac Assist System 2 (LUCAS-2) into a single basic life support (BLS) fire department first response jurisdiction served by a single private advanced life support (ALS) agency, hypothesizing that the implementation of the device would increase prehospital return of spontaneous circulation (ROSC) rates as compared with manual CPR.  Methods A retrospective observational analysis of adult non-traumatic prehospital cardiac arrest ALS agency records was conducted.
