Background Prehospital pediatric drug dosing errors occur at a high rate. Multiple factors contribute to these errors. The contribution of weight estimation errors to drug dosing errors is unknown. We describe methods used to obtain weights and resulting drug dosing errors. Methods As part of a quality improvement study in 16 EMS agencies, we conducted four simulated pediatric scenarios seizing, hypoglycemic infant, infant cardiac arrest, 18-month old burn and a 5-year old with anaphylactic shock. Crews used their regular drug bags and equipment. Simulations were observed by study team members with video review and scored on a standardized scoring sheet. Results 142 scenarios were completed. Methods to obtain patient weights were asking parent 17/142 (12.0%), patient age 35/142 (24.8%) and Broselow-Luten Tape (BLT) 89/142 (63.1%). There were 19 (13.4% 95% CI 8.5, 20.0) incorrect weight estimations resulting in 18 (12.7% 95% CI 8.2, 19.2) dosing errors (1 asking parent, 9 patient age and 8 BLT). Ten dosing errors were directly caused by weight estimation errors. In 41/89 (46.1% 95%CI 36.1, 56.4) BLT uses there was a near-miss error that did not result in a dosing error. One pound to kilogram conversion error occurred. Conclusions BLT is the most frequently used method to obtain a patient weight. Drug dosing errors were most frequent with patient age, followed by BLT and asking the parent. System-based solutions-weight determination hierarchy, not using the BLT on seated patients, and more frequent training and practice with the BLT-are needed to improve drug-dosing accuracy.Background This study investigated the potential molecular mechanism of circular RNA HIPK3 (circHIPK3) in breast cancer (BCa). Methods BCa cells were transfected with miR-326 mimic, miR-326 inhibitor, circHIPK3, sicircHIPK3. PMA activator molecular weight The expressions of circHIPK3 and miR-326 in BCa tissues and BCa cell lines were determined by RT-qPCR. Cell viability, colony formation, migration, invasion, and apoptosis of the cells were detected by CCK-8 and colony formation, wound-healing, transwell and flow cytometric assays, respectively. The relationship between circHIPK3 and miR-326 was analyzed and confirmed by circInteractome, dual-luciferase reporter, RT-qPCR, Pearson's correlation assays. Western blot and RT-qPCR were performed to determine the expressions of apoptosis-related molecules (Bcl-2, Bax, and cleaved Caspase-3) and EMT-related molecules (E-cadherin, N-cadherin, and Vimentin) in the BCa cells and tumor tissues. The tumor growth in mice was examined in a xenograft tumor model in which Ki-67 expression was determined by immunohistochemistry (IHC). Results In BCa, the expression of circHIPK3 was up-regulated and that of miR-326 was down-regulated. CircHIPK3 knockdown inhibited the cell proliferation, invasion, and migration. MiR-326 was the direct target of circHIPK3, and was inversely correlated with circHIPK3 expression. CircHIPK3 overexpression promoted proliferation, migration, invasion, apoptosis resistance, and tumor growth and up-regulated Ki-67 expression, at the same time, the expressions of Bcl-2, N-cadherin, Vimentin were up-regulated, and those of Bax, cleaved Caspase-3 and E-cadherin were inhibited. These above expressions were partially reversed by miR-326 overexpression. Conclusion CircHIPK3 sponges miR-326 to promote BCa growth and metastasis. The current findings provide a novel therapeutic target for treating BCa.Background The role of pelvic circumferential compression devices (PCCD) is to temporarily stabilize the pelvic ring, reduce its volume and to tamponade bleeding. The purpose of this study was to evaluate the effect of PCCDs on mortality and bleeding in severely injured trauma patients, using a large registry database.Methods We performed a retrospective analysis of all patients registered in the Trauma Register DGU® between 2015 and 2016. The study was limited to directly admitted patients who were alive on admission, with an injury severity score (ISS) of 9 or higher, with an Abbreviated Injury Scale AISpelvis of 3-5, aged at least 16, and with complete status documentation on pelvic circular compression devices (PCCD) and mortality. A cohort analysis was undertaken of patients suffering from relevant pelvic fractures. Data were collected on mortality and requirements for blood transfusion. The observed outcome was compared with the expected outcome as derived from version II of the Revised Injury Severity -003, March 2017; German clinical trial register DRKS00024948.Sphingosine 1-phosphate (S1P) is a multifaceted lipid signaling molecule that activates five specific G protein-coupled S1P receptors. Despite the fact that S1P is known as one of the strongest barrier-enhancing molecules for two decades, no medical application is available yet. The reason for this lack of translation into clinical practice may be the complex regulatory network of S1P signaling, metabolism and transportation.In this review, we will provide an overview about the physiology and the network of S1P signaling with the focus on endothelial barrier maintenance in inflammation. We briefly describe the physiological role of S1P and the underlying S1P signaling in barrier maintenance, outline differences of S1P signaling and metabolism in inflammatory diseases, discuss potential targets and compounds for medical intervention, and summarize our current knowledge regarding the role of S1P in the maintenance of specialized barriers like the blood-brain barrier and the placenta.Objective Relatively little has been reported about the impact of COVID-19 restrictions on emergency ambulance services. We describe the influence of the COVID-19 pandemic on the emergency ambulance system in Victoria, Australia.Methods We performed an interrupted time series analysis of consecutive calls for ambulance from January 2018 to February 2021, including two waves of COVID-19. The COVID-19 lockdown period included seven months of stay-at-home restrictions (16/03/2020-18/10/2020). Nineteen weeks of post-lockdown data were included (19/10/2020-28/02/2021).Results In total, 2,356,326 consecutive calls were included. COVID-19 lockdown was associated with an absolute reduction of 64,991 calls (almost 2,100 calls/week). According to time series analysis, lockdown was associated with a 12.6% reduction in weekly calls (IRR = 0.874 [95% CI 0.811, 0.941]), however no change in long-term trend (IRR = 1.000 [95% CI 0.996, 1.003]). During lockdown, the long-term trend of attendances to patients with suspected acute coronary syndromes (ACS, IRR = 1.
