Despite many advances in care, the mortality rate for cardiogenic shock remains high. Because the medical management of patients with cardiogenic shock is limited, many patients often require mechanical circulatory support. As such, cardiogenic shock patients requiring percutaneous ventricular support devices such as the Impella (Abiomed, Danvers, MA) may be encountered by critical care transport crews with increasing frequency. Recently, biventricular Impella support has been described as a mechanical support strategy for biventricular failure...

As the main systemic treatment for triple-negative breast cancer (TNBC), the bleak medical prognosis of chemotherapy resulted in impaired life quality by tumor recurrence and metastasis. The feasible cancer starvation therapy could inhibit tumor progression by blocking energy supplements, however, the mono-therapeutic modality showed limited curing efficacy due to heterogeneity and abnormal energy metabolism of TNBC. Thus, the development of a synergistic nano-therapeutic modality involving different anti-tumor mechanisms to simultaneously transport medicines to the organelle where metabolism took place, might remarkably improve curing efficacy, targeting ability, and bio-safety...

UNLABELLED: Despite pronouncements about the inevitable diffusion of artificial intelligence and autonomous technologies, in practice, it is human behavior, not technology in a vacuum, that dictates how technology seeps into-and changes-societies. To better understand how human preferences shape technological adoption and the spread of AI-enabled autonomous technologies, we look at representative adult samples of US public opinion in 2018 and 2020 on the use of four types of autonomous technologies: vehicles, surgery, weapons, and cyber defense...

OBJECTIVE: The coronavirus disease 2019 pandemic has resulted in unprecedented burnout in frontline health care providers. However, the impact of the pandemic on interfacility pediatric and neonatal transport team members has not been studied. The current study uses a survey design to document the impact of the pandemic on pediatric and neonatal transport team members with a focus on staffing and resilience promotion strategies. METHODS: Data for this study came from a short cross-sectional survey distributed to members of the American Academy of Pediatrics Section on Transport Medicine...

Medicinal plants have a wide range of uses worldwide. However, the quality of medicinal plants is affected by severe cadmium pollution. Cadmium can reduce photosynthetic capacity, lead to plant growth retardation and oxidative stress, and affect secondary metabolism. Medicinal plants have complex mechanisms to cope with cadmium stress. On the one hand, an antioxidant system can effectively scavenge excess reactive oxygen species produced by cadmium stress. On the other hand, cadmium chelates are formed by chelating peptides and then sequestered through vacuolar compartmentalization...

INTRODUCTION: Placement of percutaneous ventricular support devices such as an intraaortic balloon pump (IABP) or Abiomed Impella device can treat severe cardiogenic shock. Critical care transport medicine (CCTM) providers frequently manage patients supported by these devices during interfacility transfers, often using a helicopter air ambulance (HAA). An understanding of patient needs and management during transport is essential to informing crew configuration and training, and this study adds to the limited existing data on the HAA transport of this complex patient population...

Herbal treatment for diabetes mellitus is widely used. The pharmacological activity is thought to be due to the phenolic compounds found in the plant leaves. The present study aims to investigate the phytochemical composition of Urtica dioica (UD) hydroethanolic extract and to screen its antidiabetic activity by disaccharidase hindering and glucose transport in Caco-2 cells. The results have shown that a total of 13 phenolic compounds in this work, viz. caffeic and coumaric acid esters ( 1 , 2 , 4 - 7 , 10 ), ferulic derivative ( 3 ), and flavonoid glycosides ( 8 , 9 , 11 - 13 ), were identified using HPLC-DAD-ESI/MS2 ...

Automated guided vehicles (AGVs) are popular subsets of robots that come in various shapes and sizes. The group's use in the industry ranges from applications for carrying pallets, carts, and utensils to helping the elderly or transporting medicine to hospitals. Even recently, they have been used in libraries to carry books on shelves. The main part of an AGV includes its body, motor, driver, processor, and sensors, which are more or less the same in all types of AGVs, and addons vary depending on the application and the work environment...

This work aims to solve the problem that the daily necessities of urban residents cannot be delivered during coronavirus disease 2019 (COVID-19), thereby reducing the possibility of the delivery personnel contracting COVID-19 due to the need to transport medicines to the hospital during the epidemic. Firstly, this work studies the application and communication optimization technology of unmanned delivery cars based on deep learning (DL) under COVID-19. Secondly, a route planning method for unmanned delivery cars based on the DL method is proposed under the influence of factors such as maximum flight time, load, and road conditions...

Extraglottic devices (EGDs) are important tools for airway management in the prehospital and transport medicine environment. EGDs may be used as either a primary airway or rescue device depending on the provider skill level or patient circumstances. Although EGDs do not provide a definitive airway, they can facilitate oxygenation and ventilation in select patients. This is particularly important in the remote or austere environment when difficult airways are infrequently encountered. This case report details the prolonged use of an EGD during air medical transport from a rural Alaskan medical clinic to a large academic tertiary receiving facility, with the total time until definitive airway placement of approximately 9 hours...

OBJECTIVE: The aim of this study was to evaluate the feasibility of statin administration by a critical care transport medicine (CCTM) team during rotor wing transport for ST-elevation myocardial infarction patients to a percutaneous intervention-capable center. METHODS: We conducted a retrospective study at a single CCTM program after an intervention focused on statin administration for ST-elevation myocardial infarction that included a formulary change and a single brief educational presentation to flight physicians...

OBJECTIVE: Interfacility transport of critically ill infants and children is an essential part of the care of children in the United States. However, there is tremendous variation in how transports are coordinated and performed. Pediatric critical care medicine (PCCM) fellows have differing experiences in their fellowships, and there is no standardized way of training medical command for the transport process. The aim of this study was to use a consensus-building process to establish core components of a PCCM transport curriculum focused on communication...

Unique features of magnetic particles have made it possible to apply them in medical techniques. These techniques not only provide minimal invasive diagnostic tools but also transport medicine within the cell. In recent years, MRI, drug supply to infected tissue, Hyperthermia are more enhanced by the use of magnetic particles. The present study aims to observe heat and mass transport through blood flow containing magnetic particles in a cylindrical tube...

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic has altered the provision of health care, including interfacility transport of critically ill neonatal and pediatrics patients. Transport medicine faces unique challenges in the care of persons infected with the severe acute respiratory syndrome coronavirus 2. In particular, the multitude of providers, confined spaces for prolonged time periods, varying modes (ground, rotor wing, and fixed wing) of transport, and the need for frequent aerosol-generating procedures place transport personnel at high risk...

OBJECTIVE: Rapid sequence intubation (RSI) is often required in managing critically ill patients in the prehospital setting. Although etomidate is a commonly used induction agent for RSI, ketamine has gained new interest in prehospital management with reported neutral hemodynamic effects. Limited data exist to support ketamine as an alternative to etomidate, particularly in the prehospital setting. The purpose of this study was to evaluate hemodynamic changes after the administration of ketamine versus etomidate in prehospital RSI...

BACKGROUND: We aimed to evaluate the effects of interfacility pediatric critical care transport response time, physician presence during transport, and mode of transport on mortality and length of stay (LOS) among pediatric patients. We hypothesized that a shorter response time and helicopter transports, but not physician presence, are associated with lower mortality and a shorter LOS. METHODS: Retrospective, single-center, cohort study of 841 patients (< 19 years) transported to a quaternary pediatric intensive care unit and cardiovascular intensive care unit between 2014 and 2018 utilizing patient charts and transport records...
