Objective:The objective of this study was to evaluate the rapid training of medical students and their ability to provide effective manual ventilation using the bag-valve-mask technique.Methods:A rapid training session highlighting essential aspects of the correct bag-valve-mask technique was given to 31 medical students.This was followed by a simulated experience with a certified respiratory therapist, monitored according to a checklist of essential bag-valve-mask (BVM) competency requirements. Pretest and post-test surveys assessed the medical students' knowledge and ability to provide adequate BVM technique.Results:Thirty-one students participated. Presurvey results demonstrated a clear identification of the potential risk for a disaster (pandemic, natural, bioterrorist) with 55% of students responding that a definite risk did exist. Their usefulness in such an event also was ascertained with 55% of students replying they would assist with basic medical tasks, assist doctors, or assist with cardiopulmonary resuscitation. Post-survey results administered after a 30-minute didactic session on the basic features of resuscitation equipment and the essential components of BVM technique demonstrated that a majority of students knew the proper head positioning maneuvers in cases not involving trauma (93%) and in cases involving trauma (72%). All students completed and passed the competency checklist.Conclusions:Medical students can be rapidly trained and be utilized as a potential resource to carry out the potentially lifesaving task of manual ventilation using the BVM technique in a disaster situation in which the availability of mechanical ventilators and respiratory therapists may be limited.

Introduction: In October 2005, Hurricane Stan impacted Central America, causing severe damage to Guatemala. The main objectives of this study are to report on the effects of Hurricane Stan in rural Guatemala, to assess the responses of a rural clinic during and after the storm, and to identify ways in which the clinic can better prepare for future disasters. The clinic is located in Catarina, San Marcos, Guatemala. Roughly 400-500 patients are attended to each week at the clinic. Methods: Survey data were obtained during a two-week period using a convenience sample of people at the clinic and in the surrounding community. Results:The major medical problems after the impact of Hurricane Stan included fungal infections, upper respiratory infections, diarrhea, and emotional problems. The most needed supplies included food, electricity, home repair, potable water, communication, and clothing. In the immediate aftermath of event, 61% of the participants could not get to a hospital; however, most did not require medical assistance. Conclusions: Hurricane Stan had a devastating effect on the San Marcos region of Guatemala. While the clinic could have served as a resource center and a base, it was not prepared to address the community's health needs after the hurricane as there were no previous plans in place for disaster response for the clinic or for the community. Next steps include developing a preparedness plan to utilize the clinic as a local resource center , in the event that the planned national disaster responses are delayed or unable to reach the affected area.

Scholars have extensively studied whether campaign attack advertisements –messages that attack individual candidates– mobilize or demobilize voters with mixed results. We argue that group-oriented partisan affect in campaigns –messages about the parties in general– is just as important given increasing trends of affective polarization. We use two survey experiments, one right before the 2020 presidential election and the other before the subsequent Georgia Senate runoff election, to examine the effects of partisan rhetoric on several measures of civic engagement. In the presidential election, neither positive partisan, negative partisan, nor personal apartisan appeals had a statistically significant effect on voters’ enthusiasm, likelihood to volunteer, or likelihood to seek out more information about engaging in the election. In the second study, negative partisan appeals led registered voters in Georgia to report much higher levels of enthusiasm about their preferred candidate, but this result was driven by Republicans only. The findings contribute new insights about electoral context and asymmetric affective polarization to the literature documenting the mobilizing effects of negativity in campaigns.
