Transportation and equipment needs for emergency medical services development in low- and middle-income countries.

Prehospital emergency medical services play a vital role in reducing mortality and disease burden in low- and middle-income countries. However, the availability of adequate prehospital emergency care remains a significant challenge in many resource-limited communities, with over 91% of the African population lacking access to sufficient emergency medical services. This commentary aims to highlight the critical components of transportation infrastructure and medical supply chain challenges for emergency medical service development and propose potential solutions for future study. Transportation is a key factor influencing prehospital mortality, yet many low- and middle-income countries face issues related to timely prehospital transportation, with patients often relying on family members or private vehicles for transportation, leading to delays in reaching healthcare facilities due to poor road infrastructure. Dysfunctional and inadequate vehicles are also common barriers to timely care. Response times and transport times often exceed high-income standards, with some rural areas experiencing total prehospital time, defined as the time of injury to arrival at definitive care, exceeding 24 hours. To address these transportation challenges, some low- and middle-income countries have developed tier-1 emergency medical services programs that use existing transportation infrastructure and involve lay first responders using motorized and non-motorized vehicles. These programs prioritize rapid transportation over advanced on-scene intervention, potentially providing faster response times. A combination of tier-1 and tier-2 emergency medical services systems, as seen in some successful examples, allows for early on-scene guidance and resource allocation. In addition to transportation, the availability of medical equipment is crucial for effective prehospital interventions, particularly in tier-2 systems. However, low- and middle-income countries often face shortages of even basic supplies, limiting the scope of care that emergency medical services personnel can provide. Developing tier-2 emergency medical services upon a foundation of tier-1 prehospital care utilizing sustainable local supply chains and common household items for basic care can help alleviate these equipment challenges. The integration of tier-1 and tier-2 systems may offer a promising solution to address resource limitations and improve timely access to emergency care in low- and middle-income countries. Further research and investment are required to explore and implement these solutions, ultimately reducing mortality and enhancing healthcare services in resource-limited communities.

The First Statewide Implementation of a Regional Disaster Teleconsultation System to Expand Critical Care Surge Capacity: A Case Study in Vermont.

Background: In December 2021, the Region 1 Disaster Health Response System, the state of Vermont, and the National Emergency Tele-Critical Care Network partnered to provide statewide access to disaster teleconsultations during COVID-19 surge conditions. In this case report, we describe how a disaster teleconsultation system was implemented in Vermont to provide access to temporary tele-critical care consultations during the Omicron COVID-19 surge. Methods: We measured the time from request of service to implementation and calculated descriptive statistics. Results: Seven of Vermont's 14 hospitals requested the service. Despite a technology solution capable of providing services within hours, mean time to service implementation was 27 days (interquartile range 20-41 days). Conclusions: Integration of disaster teleconsultation systems into state and local emergency management plans are needed to bring administrative start-up times in line with technical readiness.

Emergency Medicine Telehealth: A Pandemic Becomes a Gateway for Virtual Care in Missouri.

Telehealth provides a novel bridge between patient needs and available resources. On-demand telehealth visits provide urgent medical services in a virtual setting. Telehealth can be used to provide care for patients despite geographical distance. Emergency Medicine quickly adapted in response to the COVID-19 pandemic through utilization of telehealth to solve various problems. Tele-triage was used to coordinate COVID-19 testing and treatment. Greater utilization of all current and emerging telehealth modalities could increase access and quality of care for all Missourians.

Development and perceptions of an academic success tool for pharmacy students.

OBJECTIVE: Some students may face challenges with graduate-level reading and writing, particularly in certain active learning pedagogies, such as team-based learning or peer instruction, which require extensive pre-reading. The objective of this study is to determine the perceived utility of an academic literacy (reading/writing) test for first professional year student pharmacists (P1s). METHODS: In a collaboration between pharmacy and linguistics faculty, an academic literacy assessment tool was developed using fall P1 course materials. After pilot testing and adjustments, the revised test was administered to all P1 students by trained facilitators, then scored. Students needing literacy support were identified, met with individually to debrief on the assessment, and offered a year-long, one-on-one tutoring program. P1 faculty participated in an end-of-semester focus group session to determine whether the assessment correctly identified students who benefited from literacy support, and to decide on the impact of subsequent support. Thematic analysis was performed on the data. RESULTS: A total of 13 students were identified as at-risk through the assessment. Since tutoring was optional, eight students met at least once, and two students met weekly during the ensuing semester. Faculty from the end-of-semester focus group 1) stated that the assessment accurately pre-identified students who struggled with literacy components of P1 coursework, and 2) expressed a wish for earlier identification of students with required instead of optional tutoring. CONCLUSIONS: Faculty perceived that the tool accurately identified students, but the timing and the volunteer nature of the follow-up tutoring limited the success of the assessment effort.

Few-layer graphene as a support film for transmission electron microscopy imaging of nanoparticles.

One consistent limitation for high-resolution imaging of small nanoparticles is the high background signal from the amorphous carbon support film. With interest growing for smaller and smaller nanostructures, state of the art electron microscopes are becoming necessary for rudimentary tasks, such as nanoparticle sizing. As a monolayer of carbon, free-standing graphene represents the ultimate support film for nanoparticle imaging. In this work, conventional high-resolution transmission electron microscopy (HRTEM) and aberration-corrected scanning transmission electron microscopy (STEM) were used to assess the benefits and feasibility of few-layer graphene support films. Suspensions of few-layer graphene to produce the support films were prepared by simple sonication of exfoliated graphite. The greatest benefit was observed for conventional HRTEM, where lattice resolved imaging of sub 2 nm CdSe nanocrystals was achieved. The few-layer graphene films were also used as a support film for C(s)-corrected STEM and electron energy loss spectroscopy of CuInSe(2) nanocrystals.

Pinned emission from ultrasmall cadmium selenide nanocrystals.

We report pinning of the emission spectrum in ultrasmall CdSe nanocrystals with a diameter of 1.7 nm and smaller. It was observed that the first emission feature ceased to blueshift once the band edge absorption reached 420 nm, though the band edge absorption continued to blueshift with decreasing nanocrystal diameter.
