A novel study of situational awareness among out-of-hospital providers during an online clinical simulation.

Background: Out-of-hospital providers must be situationally aware in order to maintain safety for themselves, their patients, the public, and their crew. They must be able to recognize situations, interpret them, and predict how those situations may unfold in the future.

Method: A mixed-methods explanatory sequential design where out-of-hospital providers in Oklahoma, USA, participated in an 18-minute online simulation and then had their situational awareness (SA) measured.

Myocardial matrix hydrogel acts as a reactive oxygen species scavenger and supports a proliferative microenvironment for cardiomyocytes.

As the native regenerative potential of adult cardiac tissue is limited post-injury, stimulating endogenous repair mechanisms in the mammalian myocardium is a potential goal of regenerative medicine therapeutics. Injection of myocardial matrix hydrogels into the heart post-myocardial infarction (MI) has demonstrated increased cardiac muscle and promotion of pathways associated with cardiac development, suggesting potential promotion of cardiomyocyte turnover. In this study, the myocardial matrix hydrogel was shown to have native capability as an effective reactive oxygen species scavenger and protect against oxidative stress induced cell cycle inhibition in vitro.

Transduction characteristics of alternative adeno-associated virus serotypes in the cat brain by intracisternal delivery.

Multiple studies have examined the transduction characteristics of different AAV serotypes in the mouse brain, where they can exhibit significantly different patterns of transduction. The pattern of transduction also varies with the route of administration. Much less information exists for the transduction characteristics in large-brained animals.

What's in a Name? Parents' and Healthcare Professionals' Preferred Terminology for Pathogenic Variants in Childhood Cancer Predisposition Genes.

Current literature/guidelines regarding the most appropriate term to communicate a cancer-related disease-causing germline variant in childhood cancer lack consensus. Guidelines also rarely address preferences of patients/families. We aimed to assess preferences of parents of children with cancer, genetics professionals, and pediatric oncologists towards terminology to describe a disease-causing germline variant in childhood cancer.

Spontaneous Volumetric Tumor Regression During Wait-and-Scan Management of 952 Sporadic Vestibular Schwannomas.

Objective: Spontaneous tumor shrinkage during wait-and-scan management of sporadic vestibular schwannoma is generally considered an uncommon phenomenon. However, most data informing this understanding stem from single-slice linear tumor measurements taken in the axial imaging plane. The objective of the current work was to characterize the regression capacity of sporadic vestibular schwannomas using volumetric tumor measurements.

COVID-19: Acing the Treatment.

Angiotensin converting enzyme 2 is the functional receptor that the SARS-Cov-2 virus requires to enter cells and cause dysregulated inflammatory conditions that contribute towards acute lung injuries. The renin-angiotensin-aldosterone system with its physiological surveillance and regulation system can be implicated in both harm and therapeutic benefit. The initial observational studies suggesting the discontinuation of angiotensin converting enzyme inhibitors and angiotensin receptor blockers have been firmly rebutted by international societies.

Toward Soft Wearable Strain Sensors for Muscle Activity Monitoring.

The force-generating capacity of skeletal muscle is an important metric in the evaluation and diagnosis of musculoskeletal health. Measuring changes in muscle force exertion is essential for tracking the progress of athletes during training, for evaluating patients' recovery after muscle injury, and also for assisting the diagnosis of conditions such as muscular dystrophy, multiple sclerosis, or Parkinson's disease. Traditional hardware for strength evaluation requires technical training for operation, generates discrete time points for muscle assessment, and is implemented in controlled settings.

Normothermic machine perfusion of kidneys: current strategies and future perspectives.

Purpose Of Review: This review aims to summarize the latest original preclinical and clinical articles in the setting of normothermic machine perfusion (NMP) of kidney grafts.

Recent Findings: Kidney NMP can be safely translated into the clinical routine and there is increasing evidence that NMP may be beneficial in graft preservation especially in marginal kidney grafts. Due to the near-physiological state during NMP, this technology may be used as an ex-vivo organ assessment and treatment platform.

Decreasing delirium through music listening (DDM) in critically ill, mechanically ventilated older adults in the intensive care unit: a two-arm, parallel-group, randomized clinical trial.

Background: Delirium is a highly prevalent and morbid syndrome in mechanically ventilated intensive care unit (ICU) patients. Music is a promising non-pharmacological intervention with beneficial effects on anxiety and stress, while its effects on delirium duration and severity are not well understood.

Methods/design: Our study is a two-arm, randomized parallel-group, clinical trial to evaluate the efficacy of music intervention compared to a silence-track attention control on delirium/coma duration in mechanically ventilated critically ill older adults.

Left-wing support of authoritarian submission to protect against societal threat.

New Zealand's Prime Minister, Jacinda Ardern, adopted a "go hard, go early" approach to eliminate COVID-19. Although Ardern and her Labour party are considered left-leaning, the policies implemented during the pandemic (e.g.

Developing a global practice-based framework of person-centred care from primary data: a cross-national qualitative study with patients, caregivers and healthcare professionals.

Introduction: Person-centred care (PCC) is internationally recognised as a critical component of high-quality healthcare. However, PCC evolved in a few high-income countries and there are limited data exploring this concept across the vast majority of countries which are low- and middle-income. This study aimed to appraise and adapt a PCC model across three serious physical conditions in three middle-income countries and generate an evidence-based framework and recommendations for globally relevant PCC.

FOXR2 Is an Epigenetically Regulated Pan-Cancer Oncogene That Activates ETS Transcriptional Circuits.

Unlabelled: Forkhead box R2 (FOXR2) is a forkhead transcription factor located on the X chromosome whose expression is normally restricted to the testis. In this study, we performed a pan-cancer analysis of FOXR2 activation across more than 10,000 adult and pediatric cancer samples and found FOXR2 to be aberrantly upregulated in 70% of all cancer types and 8% of all individual tumors. The majority of tumors (78%) aberrantly expressed FOXR2 through a previously undescribed epigenetic mechanism that involves hypomethylation of a novel promoter, which was functionally validated as necessary for FOXR2 expression and proliferation in FOXR2-expressing cancer cells.

Characterization of decellularized left and right ventricular myocardial matrix hydrogels and their effects on cardiac progenitor cells.

Congenital heart defects are the leading cause of right heart failure in pediatric patients. Implantation of c-kit cardiac-derived progenitor cells (CPCs) is being clinically evaluated to treat the failing right ventricle (RV), but faces limitations due to reduced transplant cell survival, low engraftment rates, and low retention. These limitations have been exacerbated due to the nature of cell delivery (narrow needles) and the non-optimal recipient microenvironment (reactive oxygen species (ROS)).

Multi-center validation of an artificial intelligence system for detection of COVID-19 on chest radiographs in symptomatic patients.

Objectives: While chest radiograph (CXR) is the first-line imaging investigation in patients with respiratory symptoms, differentiating COVID-19 from other respiratory infections on CXR remains challenging. We developed and validated an AI system for COVID-19 detection on presenting CXR.

Methods: A deep learning model (RadGenX), trained on 168,850 CXRs, was validated on a large international test set of presenting CXRs of symptomatic patients from 9 study sites (US, Italy, and Hong Kong SAR) and 2 public datasets from the US and Europe.

Prevalence of Tardive Dyskinesia in an Electronic Medical Record Study at a Large Community Mental Health Treatment Center.

To determine the prevalence of tardive dyskinesia (TD) identified by clinicians in naturalistic data in a real-world treatment setting. Electronic medical record data were analyzed from a single large community mental health treatment center for all psychiatric provider encounters of 120,431 unique adult and child patients during a 5-year period from January 2013 through December 2017, focusing on clinician-identified TD in patients prescribed antipsychotic medication. Only half of the antipsychotic-prescribed patients had Abnormal Involuntary Movement Scale (AIMS) information recorded in their medical records, and only 1% of those with AIMS data had a positive AIMS identifying TD.
