Potential technique for improving the survival of victims of tsunamis.

ABSTRACT: We investigated a method for surviving tsunamis that involved the use of personal flotation devices (PFDs). In our work, we succeeded in numerically demonstrating that the heads of all the dummies wearing PFDs remained on the surface and were not dragged underwater after the artificial tsunami wave hit them. In contrast, the heads of all the dummies not wearing PFDs were drawn underwater immediately; these dummies were subsequently entrapped in a vortex. The results of our series of experiments are important as a first step to preventing the tragedies caused by tsunamis.

The Witness-Aimed First Account (WAFA): A new technique for interviewing autistic witnesses and victims.

Project description:Lay abstractAutistic people may be more likely to be interviewed by police as a victim/witness, yet they experience social communication difficulties alongside specific memory difficulties that can impact their ability to recall information from memory. Police interviewing techniques do not take account of these differences, and so are often ineffective. We developed a new technique for interviewing autistic witnesses, referred to a Witness-Aimed First Account, which was designed to better support differences in the way that autistic witnesses process information in memory. The Witness-Aimed First Account technique encourages witnesses to first segment the witnessed event into discrete, parameter-bound event topics, which are then displayed on post-it notes while the witness goes onto freely recall as much information as they can from within each parameter-bound topic in turn. Since witnessed events are rarely cohesive stories with a logical chain of events, we also explored autistic and non-autistic witnesses' recall when the events were witnessed in a random (nonsensical) order. Thirty-three autistic and 30 typically developing participants were interviewed about their memory for two videos depicting criminal events. Clip segments of one video were 'scrambled', disrupting the event's narrative structure; the other video was watched intact. Although both autistic and non-autistic witnesses recalled fewer details with less accuracy from the scrambled video, Witness-Aimed First Account interviews resulted in more detailed and accurate recall from both autistic and non-autistic witnesses, for both scrambled and unscrambled videos. The Witness-Aimed First Account technique may be a useful tool to improve witnesses' accounts within a legally appropriate, non-leading framework.

Improving Nasopharyngeal Swab Technique via Simulation for Frontline Workers.

Project description:Nasopharyngeal swabs currently remain the gold standard for COVID-19 sample collection. A surge in testing volume has resulted in a large number of health care workers who are unfamiliar with nasal anatomy performing this test, which can lead to improper collection practices culminating in false-negative results and complications. Therefore, we aimed to assess the accuracy and educational potential of a realistic 3D-printed nasal swab simulator to expedite health care workers' skill acquisition. Prospective pre-post interventional study. A nasal swab task trainer (NSTT) was developed to scale from computed tomography data with a deviated septum. Frontline workers at COVID-19 testing sites in Ontario, Canada, were recruited to use the NSTT for nasopharyngeal swab training. Integrated video recording capability allowed participants to self-evaluate procedure accuracy. A five-point Likert scale was collected regarding the NSTT's educational value and procedural fidelity. Sixty-two frontline workers included in the study were primarily registered nurses (52%) or paramedics (16%). Following simulator use, self-assessed accuracy improved in 77% of all participants and 100% of participants who expressed low confidence before training. Ninety-four percent reported that the NSTT provided a complete educational experience, and 82% regarded the system as a more effective training approach than what is currently available. Eighty-one indicated that the simulator should be used at all COVID-19 testing sites, with 77% stating province-wide implementation was warranted. The nasal swab task trainer is an effective educational tool that appears well-suited for improved skill acquisition in COVID-19 testing and may be useful for training other nasal swab applications. 3 Laryngoscope, 2022.

Thermosonication Combined with Natural Antimicrobial Nisin: A Potential Technique Ensuring Microbiological Safety and Improving the Quality Parameters of Orange Juice.

Project description:Currently, thermal pasteurisation (TP) remains the most widely applied technique for commercial orange juice preservation; however, a high temperature causes adverse effects on the quality attributes of orange juice. In order to explore a novel non-thermal sterilization method for orange juice, the impacts of thermosonication combined with nisin (TSN) and TP treatments on the quality attributes including microbial and enzyme inactivation and the physicochemical, nutritional, functional, and sensory qualities of orange juice were studied. Both TP and TSN treatments achieved desirable bactericidal and enzyme inactivation effects, and nisin had a significant synergistic lethal effect on aerobic bacteria in orange juice (p < 0.05). Additionally, TSN treatment significantly improved the color attributes of orange juice and well maintained its physicochemical properties and sensory quality. More importantly, TSN treatment significantly increased the total polyphenols content (TPC) and total carotenoids (TC) by 10.03% and 20.10%, increased the ORAC and DPPH by 51.10% and 10.58%, and the contents of total flavonoids and ascorbic acid were largely retained. Correlation analysis of antioxidant activity showed that the ORAC and scavenging ability of DPPH radicals of orange juice are mainly attributed to TC and TPC. These findings indicate that TSN shows great potential application value, which could guarantee the microbiological safety and improve the quality attributes of orange juice.

Virtuous victims.

Project description:How do people perceive the moral character of victims? We find, across a range of transgressions, that people frequently see victims of wrongdoing as more moral than nonvictims who have behaved identically. Across 17 experiments (total n = 9676), we document this Virtuous Victim effect and explore the mechanisms underlying it. We also find support for the Justice Restoration Hypothesis, which proposes that people see victims as moral because this perception serves to motivate punishment of perpetrators and helping of victims, and people frequently face incentives to enact or encourage these “justice-restorative” actions. Our results validate predictions of this hypothesis and suggest that the Virtuous Victim effect does not merely reflect (i) that victims look good in contrast to perpetrators, (ii) that people are generally inclined to positively evaluate those who have suffered, or (iii) that people hold a genuine belief that victims tend to be people who behave morally.

Serum Cortisol Levels as a Predictor of Neurologic Survival inSuccessfully Resuscitated Victims of Cardiopulmonary Arrest.

Project description:Out-of-hospital cardiac arrest (OHCA) is the most stressful lifetime event for the victims and an important issue for the emergency physicians. The status of the hypothalamic pituitary- adrenal axis (HPA) function in successfully resuscitated victims of cardiopulmonary arrest has been recently of an interest for the researchers.In a prospective cohort study, 50 successfully resuscitated OHCA victims' serum cortisol levels were measured 5 minutes and 1 hour after return of spontaneous circulation (ROSC). The data were analyzed comparing the one-week neurologic survival.Fifty blood samples were obtained for serum cortisol levels after 5 minutes of ROSC. Fourteen patients (28%) pronounced death during one hour after CPR. Blood sample from living 36 patients after one hour post-CPR were obtained for second cortisol assay. Eleven patients (22%) were neurologically survived after one week. Seven patients (14%) were discharged finally from hospital with good neurologic recovery. The serum cortisol levels in both the neurologically surviving and the non-surviving after 5 minutes of ROSC patients were 63.4 ±13.6 and 43.2±25.5(microg/ml), (mean±S.D., respectively) and after 1 hour of ROSC patients' serum cortisol levels were 64.9±13.1 and 47.3±27.1(microg/ml), (mean±S.D., respectively). The difference was significantly higher in neurologically survived group in both 5 minutes and 1 hour after ROSC (P= 0.015 and 0.013 respectively).serum cortisol levels after 5 minutes and one hour of ROSC in victims of cardiopulmonary arrest are significantly higher in neurologically survived than non-survived patients.

Improving Quality of Care in Hospitals for Victims of Elder Mistreatment: Development of the Vulnerable Elder Protection Team.

Project description:Problem definitionHospitals have an opportunity to improve the quality of care provided to a particularly vulnerable population: victims of elder mistreatment. Despite this, no programs to prevent or stop elder abuse in the acute care hospital have been reported. An innovative, multidisciplinary emergency department (ED)-based intervention for elder abuse victims, the Vulnerable Elder Protection Team (VEPT), was developed at NewYork-Presbyterian / Weill Cornell Medical Center (New York City).ApproachThe VEPT is a consultation service available 24 hours a day/7 days a week to improve identification, comprehensive assessment, and treatment for potential victims of elder abuse or neglect. All ED providers have been trained on how to recognize signs of elder mistreatment. Any provider can activate the VEPT via a single page/telephone call, which triggers the VEPT's often time-consuming, complex assessment of the potential mistreatment victim. First, the ED social worker on duty performs the initial bedside assessment and separately interviews the potential perpetrator and/or caregiver. He or she then contacts the on-call VEPT medical provider to discuss next steps and other team members' potential involvement. For patients admitted to the hospital, the VEPT connects with the inpatient social workers and medical team to ensure appropriate follow-up and care planning.Next steps/planned evaluationThe VEPT program was launched in April 2017 after comprehensive training. Its impact will be measured by tracking the short-term and long-term mistreatment-related outcomes, as well as medical, mental health, functional, psychosocial, and legal outcomes of the vulnerable ED patients for whom the team provides care.

Mesenchymal Stem Cells Reduce Inflammation while Enhancing Bacterial Clearance and Improving Survival in Sepsis

Project description:Expression data from Total RNA extracted from murine spleen. Sepsis was induced in C57Bl/6J mice by cecal ligation and puncture (CLP), followed 6 hours later by an intravenous injection of Mesenchymal Stem Cell (MSC) or saline. Twenty-eight hours after CLP, plasma, bronchoalveolar lavage (BAL) fluid and tissues were collected for analyses. Total RNA was extracted using Trizol (as per manufactures' instruction) followed by clean-up procedure using Qiagen RNA easy Prep (as per manufactures instructions) In the following study we hypothesized that mesenchymal stem cells (MSCs), which have documented immunomodulatory properties, would reduce sepsis-associated inflammation and organ injury in a clinically relevant model of sepsis. To identify the molecular changes associated with decreased inflammation in CLP-injured mice treated with MSCs, we analyzed the gene expression profiles from spleens collected at 28 hours from 4 animals per group: sham/saline, CLP/saline, and CLP/MSCs.

From laboratory experiments to geophysical tsunamis generated by subaerial landslides.

Project description:Modeling of tsunami waves generated by subaerial landslides is important to provide accurate hazard and risk assessments in coastal areas. We perform small-scale laboratory experiments where a tsunami-like wave is generated by the gravity-driven collapse of a subaerial granular column into water. We show that the maximal amplitude reached near-shore by the generated wave in our experiments is linked to the instantaneous immersed volume of grains and to the ultimate immersed deposit. Despite the differences in scale and geometry between our small-scale experiments and the larger-scale geophysical events, a rather good agreement is found between the experimental law and the field data. This approach offers an easy way to estimate the amplitude of paleo-tsunamis.

Frequency dispersion amplifies tsunamis caused by outer-rise normal faults.

Project description:Although tsunamis are dispersive water waves, hazard maps for earthquake-generated tsunamis neglect dispersive effects because the spatial dimensions of tsunamis are much greater than the water depth, and dispersive effects are generally small. Furthermore, calculations that include non-dispersive effects tend to predict higher tsunamis than ones that include dispersive effects. Although non-dispersive models may overestimate the tsunami height, this conservative approach is acceptable in disaster management, where the goal is to save lives and protect property. However, we demonstrate that offshore frequency dispersion amplifies tsunamis caused by outer-rise earthquakes, which displace the ocean bottom downward in a narrow area, generating a dispersive short-wavelength and pulling-dominant (water withdrawn) tsunami. We compared observational evidence and calculations of tsunami for a 1933 Mw 8.3 outer-rise earthquake along the Japan Trench. Dispersive (Boussinesq) calculations predicted significant frequency dispersion in the 1933 tsunami. The dispersive tsunami deformation offshore produced tsunami inundation heights that were about 10% larger than those predicted by non-dispersive (long-wave) calculations. The dispersive tsunami calculations simulated the observed tsunami inundation heights better than did the non-dispersive tsunami calculations. Contrary to conventional practice, we conclude that dispersive calculations are essential when preparing deterministic hazard maps for outer-rise tsunamis.
