RESUMEN

BACKGROUND: miniSTONE-2 (NCT03629184) was a global, phase 3, randomized, controlled study that investigated the safety and efficacy of single-dose baloxavir marboxil in otherwise healthy children 1-<12 years of age and showed a positive risk-benefit profile. This post hoc analysis evaluated the safety and efficacy of baloxavir versus oseltamivir in children 5-11 years old with influenza. METHODS: Children received single-dose baloxavir or twice-daily oseltamivir for 5 days. Safety was the primary objective. Efficacy and virological outcomes included time to alleviation of symptoms, duration of fever and time to cessation of viral shedding by titer. Data were summarized descriptively. RESULTS: Ninety-four children 5-11 years old were included (61 baloxavir and 33 oseltamivir). Baseline characteristics were similar between the groups. The incidence of adverse events was balanced and low in both treatment groups, with the most common being vomiting (baloxavir 5% vs. oseltamivir 18%), diarrhea (5% vs. 0%) and otitis media (0% vs. 5%). No serious adverse events or deaths occurred. Median (95% CI) time to alleviation of symptoms with baloxavir was 138.4 hours (116.7-163.4) versus 126.1 hours (95.9-165.7) for oseltamivir; duration of fever was comparable between groups [41.2 hours (23.5-51.4) vs. 51.3 hours (30.7-56.8), respectively]. Median time to cessation of viral shedding was shorter in the baloxavir group versus oseltamivir (1 vs. ≈3 days). CONCLUSIONS: Safety, efficacy and virological results in children 5-11 years were similar to those from the overall study population 1-<12 years of age. Single-dose baloxavir provides an additional treatment option for pediatric patients 5-11 years old with influenza.

RESUMEN

Trauma is the number one cause of death among Americans between the ages of 1 and 46 years, costing more than $670 billion a year. Following death related to central nervous system injury, hemorrhage accounts for the majority of remaining traumatic fatalities. Among those with severe trauma that reach the hospital alive, many may survive if the hemorrhage and traumatic injuries are diagnosed and adequately treated in a timely fashion. This article aims to review the recent advances in pathophysiology management following a traumatic hemorrhage as well as the role of diagnostic imaging in identifying the source of hemorrhage. The principles of damage control resuscitation and damage control surgery are also discussed. The chain of survival for severe hemorrhage begins with primary prevention; however, once trauma has occurred, prehospital interventions and hospital care with early injury recognition, resuscitation, definitive hemostasis, and achieving endpoints of resuscitation become paramount. An algorithm is proposed for achieving these goals in a timely fashion as the median time from onset of hemorrhagic shock and death is 2 h.

RESUMEN

BACKGROUND: Responses to the COVID-19 pandemic impose significant limitations on clinical education in emergency medicine. METHODS: An emergency physician with smart glasses technology (SGT) was deployed into our emergency department (ED) to identify, enable, and curate a remote ED clinical learning experience for preclinical medical students in lieu of onsite shadowing. Students were assigned to one of four (2-h) sessions in May or June 2020. RESULTS: All 22 students participated remotely and responded to postrotation surveys. Feedback showed enthusiastic acceptance by instructors and students. Difficulty with technology was minimal. All students "strongly agreed" that they would participate in future sessions. CONCLUSIONS: This SGT instructional method represents a feasible and effective strategy to expose preclinical medical students to clinical medicine in the ED.

RESUMEN

BACKGROUND: Trauma providers seek to accurately assess the risk of patients with abdominal seat belt sign (ASBS). As hospital costs continue to rise, identification of strategies to safely discharge emergency department (ED) patients has become crucial. OBJECTIVES: The purpose of this study is to 1) describe a large cohort of patients by type of ASBS and 2) determine the value of computed tomography (CT) of the abdomen and pelvis as a screening tool to rule out intra-abdominal injury (IAI) and support discharge of stable patients. METHODS: We conducted a retrospective case series of all patients presenting to our urban, Level I trauma center from 2013-2015. We studied motor vehicle collision patients who presented with ASBS. We further classified individuals into ASBS groups: Abrasion, Ecchymosis, Abrasion + Ecchymosis, or Unknown ASBS to examine differences between groups. RESULTS: In one of the largest described cohorts, the ASBS remained associated with IAI, most commonly, solid organ injury. Of 425 patients, 36.1% had some IAI on CT, but only 13.6% required laparotomy. Categorizing the type of skin injury in ASBS, we found that both abrasion and ecchymosis were associated with IAI. Initial CT performed with 100% sensitivity. CONCLUSIONS: This study shows that ED trauma patients with significant seat belt abrasion or contusion can have IAI. With the very high sensitivity of modern abdominal CT scanners, clinicians could consider safe ED discharge of stable ASBS patients while providing strong return precautions. Our large cohort strengthens the evidence on decision-making in ASBS patients to ensure outcomes and use of health care resources.

RESUMEN

To demonstrate the capability of computer vision analysis to detect atypical orienting and attention behaviors in toddlers with autism spectrum disorder. One hundered and four toddlers of 16-31 months old (mean = 22) participated in this study. Twenty-two of the toddlers had autism spectrum disorder and 82 had typical development or developmental delay. Toddlers watched video stimuli on a tablet while the built-in camera recorded their head movement. Computer vision analysis measured participants' attention and orienting in response to name calls. Reliability of the computer vision analysis algorithm was tested against a human rater. Differences in behavior were analyzed between the autism spectrum disorder group and the comparison group. Reliability between computer vision analysis and human coding for orienting to name was excellent (intra-class coefficient 0.84, 95% confidence interval 0.67-0.91). Only 8% of toddlers with autism spectrum disorder oriented to name calling on >1 trial, compared to 63% of toddlers in the comparison group (p = 0.002). Mean latency to orient was significantly longer for toddlers with autism spectrum disorder (2.02 vs 1.06 s, p = 0.04). Sensitivity for autism spectrum disorder of atypical orienting was 96% and specificity was 38%. Older toddlers with autism spectrum disorder showed less attention to the videos overall (p = 0.03). Automated coding offers a reliable, quantitative method for detecting atypical social orienting and reduced sustained attention in toddlers with autism spectrum disorder.
