Introduction: Trauma is the leading cause of death for young Americans. Increased school violence, combined with an emphasis on early hemorrhage control, has boosted demand to treat injuries in schools. Meanwhile, coronavirus disease 2019 (COVID-19) has made educating the public about trauma more difficult. A federally funded high school education program in development, called First Aid for Severe Trauma™ (FAST™), will teach students to aid the severely injured. The program will be offered in instructor-led, web-based, and blended formats. We created a program to prepare high school teachers to become FAST instructors via “virtual” in-person (VIP) instruction. We used a webinar followed by VIP skills practice, using supplies shipped to participants’ homes. To our knowledge, no prior studies have evaluated this type of mass, widely distributed, VIP education.Methods: This study is a prospective, single-arm, educational cohort study. We enrolled a convenience sample of all high school teachers attending FAST sessions at the Health Occupations Students of America–Future Health Professionals International Leadership Conference. Half of the participants were randomized to complete the Stop the Bleed Education Assessment Tool (SBEAT) prior to the webinar, and the other completed it afterward; SBEAT is a validated tool to measure learning of bleeding competencies. We then performed 76 VIP video-training sessions from June–August 2020. The FAST instructors assessed each participant’s ability to apply a tourniquet and direct pressure individually, then provided interactive group skills training, and finally re-evaluated each participant’s performance post-training.Results: A total of 190 (96%) participants successfully applied a tourniquet after VIP training, compared to 136 (68%) prior to training (P < 0.001). Participants significantly improved their ability to apply direct pressure: 116 (56%) pre-assessment vs 204 (100%) post-assessment (P < 0.001). The mean score for the SBEAT increased significantly from pre-training to post-training: 2.09 with a standard deviation (SD) of 0.97 to 2.55 post-training with a SD of 0.72 (P < 0.001).Conclusion: This study suggests that a webinar combined with VIP training is effective for teaching tourniquet and direct-pressure application skills, as well as life-threatening bleeding knowledge. VIP education may be useful for creating resuscitative medicine instructors from distributed locations, and to reach learners who cannot attend classroom-based instruction.

Caring for patients in the intensive care unit (ICU) creates competing priorities of interventions for nurses and other health care providers. Oral care might be prioritized lower; however, its neglect may lead to sequelae such as extended time in the ICU, nosocomial diseases most notably ventilator-associated pneumonia (VAP), or oral problems. Safe patient care depends on effective and efficient oral care. The aim of this study was to lower the incidence of VAP and maintain oral health through implementing an “oral care bundle” for mechanically ventilated (MV) patients. Using a quasi-experimental design, we divided 82 adult MV patients in the ICUs of a university-based hospital in Egypt into a control group (n = 41) that received the standard of care and a bundle group (n = 41) that received an “oral care bundle.” The results of the study reported a significantly lower incidence of VAP in the intervention group (P = .015). It can be concluded that there is a significant relationship between receiving an oral care bundle and improved oral health and a reduction in the VAP rate among MV patients. This highlights the need to incorporate the oral care bundle in the daily nursing care for MV patients. [ABSTRACT FROM AUTHOR]

Background: Increasing lay responder cardiopulmonary resuscitation and automated external defibrillator use during sudden cardiac arrest depends on an individual's choice. Investigators designed and piloted an instrument to measure the affective domain of helping behaviors by applying the theory of planned behavior (TPB) to better understand lay responders' intent to use lifesaving skills. Method: Questionnaire items were compiled into 10 behavioral domains informed by the TPB constructs followed by refinement via piloting and expert review. Two samples from an American Red Cross-trained lay-responder population (N = 4,979) provided data for an exploratory (EFA, n = 235) and confirmatory (CFA, n = 198) factor analyses. EFA derived interitem relationships into factors and affective subscales. CFA yielded statistical validation of factors and subscales. Results: The EFA identified four factors, aligned with the TPB constructs of attitudes, norms, confidence, and intention to act to explain 57% of interitem variance. The internal consistency of factor-derived subscales ranged between 0.71 and 0.91. Reduction of instrument items went from 47 to 32 (32%). The CFA yielded good model fit with the switching of the legal ramification item from the social norm to intention construct. Conclusion: The Intent to Aid (I2A) survey derived from this investigation aligned with the constructs of the TPB yielding four subscales. The I2A allows health education researchers to differentiate modalities and content impact on learner intention to act in a first aid (FA) emergency. I2A compliments cognitive and psychomotor measurements of learning outcomes. The experimental instrument aims to allow curricula developers and program evaluators a means of assessing the affective domain of human learning regarding intention-to-act in an FA emergency. In combination of with assessment of functional knowledge and essential skills, this instrument may provide curricula developers and health educators an avenue to better describe intention to act in an FA emergency.

A gas-phase route such as molecular layer deposition has been applied for the first time to create a monolayer of metalorganic Eu(III) molecules on NiO oxide layer. The surface of the as-deposited NiO layer is activated using H 2 O/O 2 vapors, and then functionalized by anchoring molecules of the Eu complex working at different temperatures to favor the chemisorption process. The effects of the activation process and of the MLD temperature on the chemisorption of the Eu complex were evaluated through in-depth X-ray photoelectron and luminescence spectroscopy studies. These analyses allowed to define the stoichiometry of the Eu moiety chemisorbed on the surface and the optimization of an impressive strategy to the synthesis of hybrid metalorganic/inorganic systems. The hybrid system's luminescence properties have proved the monolayer's energy conversion phenomena and produced further information about the local environment around the Eu(III) anchored as a complex on the NiO surface. [Display omitted] • MLD has been applied for the first time to the synthesis of a monolayer on oxide substrates. • XPS measurements have confirmed the chemisorption of the Eu molecules to the NiO film substrate. • Luminescence measurements have proved the monolayer's energy conversion properties. • This approach represents a facile, time-saving method, scalable at industrial level, to produce hybrid inorganic/metalorganic systems.

Background: The aim of this study, performed in outpatients, is to evaluate, using echo color Doppler examination, atherosclerotic lesions of extracranial carotid arteries in subjects with bilateral, and monolateral dolichoarteriopathies., Methods: A total of 316 subjects, 77 with bilateral and 239 with monolateral dolichoarteriopathies, were studied. Patients were divided into: 79 subjects without cardiovascular risk factors and 237 subjects with cardiovascular risk factors (98 with arterial hypertension alone, 85 with arterial hypertension associated with other cardiovascular risk factors, 54 with hypercholesterolemia, diabetes, cigarette smoking, alone or associated). Myointimal thickness, as a mean of 5 measurements at common carotid level, 2-3 cm from flow-divider and plaques as a focal thickness =/> 2 mm, were evaluated., Results: In 77 patients with bilateral dolichoarteriopathies, compared to 239 patients with monolateral dolichoarteriopathies, there were no differences in myointimal thickening, and in the prevalence of carotid plaques; no difference was observed between sexes. Both in subjects with and without cardiovascular risk factors myointimal thickness and carotid plaques didn't show any significant differences in bilateral compared with monolateral dolichoarteriopathies., Conclusions: In conclusion, bilateral, compared with monolateral, dolichoarteriopathies of the carotids, do not seem to be a consequence of atherosclerotic lesions.

Background: The aim of this study was to evaluate the prevalence of atherosclerotic carotid lesions in isolated systolic borderline arterial hypertension by 2D echo color-Doppler and effect of night-time pressure fall by ambulatory blood pressure monitoring., Methods: Outpatients from January 1992 to December 1998 were examined. One hundred and twenty normotensive control subjects and 99 isolated systolic borderline untreated hypertensives were studied, based on blood pressure fall were divided into dippers, with nocturnal systolic and/or diastolic blood pressure fall of >10%, and non dippers. Subjects with ischemic heart disease, valvulopathies, heart failure, renal insufficiency, cerebrovasculopathies, hypercholesterolemia (total cholesterol >200 mg/dl) and diabetes. Normotensives and hypertensives were homogenous for cardiovascular risk factors. A thickness of =/> 0.95 mm, calculated as a mean of 5 measurements of the common carotid artery, 2-3 cm from the carotid bifurcation, was considered a sign of myointimal thickening, and the plaque as a focal thickening of =/> 2 mm, based on echogenic characteristics and site., Results: Compared to normotensives, isolated systolic borderline hypertensives, showed carotid arteries with an intima-media thickening (p=0.002) with one or more plaques (p=0.0001) much more frequently, while normal carotid arteries (p=0.0001) were less frequent. In normotensives, like in hypertensives, the prevalence of vasal lesions was not significantly different in dippers compared with non dippers. Plaques were most often localized at level of the common carotid and lesions were hard., Conclusions: The conclusions is drawn that isolated systolic hypertension is the sign of major vascular atherosclerotic lesions. The night-time pressure fall does not affect the importance of the lesions.
