An Issue Worth Tackling: Chronic Traumatic Encephalopathy in the National Football League

America has become a sports empire over the past century. As the movie Concussion put it, the National Football League has single-handedly taken over the day that used to belong to the church–but this comes at a price. Chronic traumatic encephalopathy, or CTE, is a life-altering disease associated with high impact and contact sports that has created a heated debate in our sports-driven society. A study published in 2017 discovered CTE in 177 of 202 former football players–or a staggering 87%. Why do the players continue to play in the NFL if their longevity and well-being are jeopardized? Why has the NFL not taken action to protect the athletes? This review, focused on American football, works to shed light on this serious and complex issue while approaching it from a multitude of intriguing and provoking angles

Assessing Perceptions of Group Work Using Team-Based Learning

Group work is frequently incorporated into courses; however, student perceptions of their experiences and the benefits of group work might differ based on the structure of course. In this study, we examined student perceptions of group work in a team-based learning (TBL) course. Undergraduate students completed pre- and post-surveys on their team work experiences over a semester. Students had lower agreement with the statement “working in groups usually ends up with one person doing all of the work” and higher agreement with “working in a group makes me feel as though I am part of a learning community” at post-test. On an open-ended question comparing their group work experiences in the TBL setting to previous group work experiences, students had positive reactions, indicating that their teammates were prepared, accountable, and worked well together. While our small sample size leaves room to examine individuals’ different experiences with group work more closely, as a whole, TBL appears to provide a structure for group work that ensures individual accountability prior to team work and to provide a space for students to practice transferable skills valued by employers

Paramedic experiences of providing care in Wales (UK) during the 2020 COVID-19 pandemic (PECC-19): a qualitative study using evolved grounded theory

Objective: To explore paramedic experiences of providing care during the 2020 COVID-19 pandemic and develop theory in order to inform future policy and practice. Design: Qualitative study using constructivist evolved grounded theory (EGT) methodology. One-to-one semistructured interviews were conducted using a general interview guide. Voice over Internet Protocol was used through Skype. Setting: Conducted between March 2020 and November 2020 in the Welsh Ambulance Services National Health Services Trust UK which serves a population of three million. Participants: Paramedics were recruited through a poster circulated by email and social media. Following purposive sampling, 20 Paramedics were enrolled and interviewed. Results: Emergent categories included: Protect me to protect you, Rapid disruption and adaptation, Trust in communication and information and United in hardship. The Basic Social Process was recognised to involve Tragic Choices, conceptualised through an EGT including Tragic personal and professional choices including concerns over personnel protective equipment (PPE), protecting themselves and their families, impact on mental health and difficult clinical decisions, Tragic organisational choices including decision making support, communication, mental health and well-being and Tragic societal choices involving public shows of support, utilisation and resourcing of health services. Conclusions: Rich insights were revealed into paramedic care during the COVID-19 pandemic consistent with other research. This care was provided in the context of competing and conflicting decisions and resources, where Tragic Choices have to be made which may challenge life’s pricelessness. Well-being support, clinical decision making, appropriate PPE and healthcare resourcing are all influenced by choices made before and during the pandemic, and will continue as we recover and plan for future pandemics. The impact of COVID-19 may persist, especially if we fail to learn, if not we risk losing more lives in this and future pandemics and threatening the overwhelming collective effort which united society in hardship when responding to the COVID-19 Pandemic.

This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). https://creativecommons.org/licenses/by/4.0/Objectives: We aimed to identify, appraise, and synthesise the qualitative literature to develop theory on heroism and paramedic practice. Hypothesis/research question: What does published literature tell us about heroism and paramedic practice? Setting: Paramedics and other healthcare workers (HCWs) faced an outpouring of public support for them early in the COVID-19 pandemic which brought into focus the relationship between them and society, where they are portrayed as heroes. Participants: We conducted a metasynthesis using Evolved Grounded Theory and procedural guidelines of Noblit and Hare to guide analysis. Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols (PRISMA-P) guidelines were also applied. Results: 151 papers were retrieved and eleven included in the final sample. Studies were moderate to very low quality, involving a wide range of methodologies and settings; none specifically explored heroism and paramedic practice. The following interrelated themes were constructed on heroism and paramedic practice: (a) Myth, Folk law, and storytelling in heroism and paramedic practice (b) The epic journey of heroism and paramedic practice (c) Heroes and Zeroes: The fluctuating Societal Value in heroism and paramedic practice (d) Politicisation, and objectification in Heroism and Paramedic practice. Conclusion: Paramedics have long been characterised as heroes, but this may not reflect their everyday experiences. Heroism in paramedic practice can provide scripts for prosocial action, inspiring others, and leading to more social heroic actions. Paramedics may however be ambivalent to such heroism narratives, due to politicisation, and objectification in the media and society. This metasynthesis is only one of many possible constructions of heroism and paramedic practice and is the first point in making sense of and developing theory on heroism and paramedic practice.

Kin-Aggregations Explain Chaotic Genetic Patchiness, a Commonly Observed Genetic Pattern, in a Marine Fish

The phenomenon of chaotic genetic patchiness is a pattern commonly seen in marine organisms, particularly those with demersal adults and pelagic larvae. This pattern is usually associated with sweepstakes recruitment and variable reproductive success. Here we investigate the biological underpinnings of this pattern in a species of marine goby Coryphopterus personatus. We find that populations of this species show tell-tale signs of chaotic genetic patchiness including: small, but significant, differences in genetic structure over short distances; a non-equilibrium or “chaotic” pattern of differentiation among locations in space; and within locus, within population deviations from the expectations of Hardy-Weinberg equilibrium (HWE). We show that despite having a pelagic larval stage, and a wide distribution across Caribbean coral reefs, this species forms groups of highly related individuals at small spatial scales (metres). These spatially clustered family groups cause the observed deviations from HWE and local population differentiation, a finding that is rarely demonstrated, but could be more common than previously thought

Evaluation of environmental sampling methods for detection of Staphylococcus aureus on fomites

We evaluated a variety of methods to recover S. aureus from inanimate surfaces. Two contact agar plates and three swab sampling methods were tested on porous and non-porous surfaces and bar soap. The cost and ease of use of each method was also evaluated. S. aureus was recovered using all methods on both porous and non-porous surfaces. S. aureus could not be detected on three of four brands of soap

The Building Blocks of Interoperability. A Multisite Analysis of Patient Demographic Attributes Available for Matching.

BackgroundPatient matching is a key barrier to achieving interoperability. Patient demographic elements must be consistently collected over time and region to be valuable elements for patient matching.ObjectivesWe sought to determine what patient demographic attributes are collected at multiple institutions in the United States and see how their availability changes over time and across clinical sites.MethodsWe compiled a list of 36 demographic elements that stakeholders previously identified as essential patient demographic attributes that should be collected for the purpose of linking patient records. We studied a convenience sample of 9 health care systems from geographically distinct sites around the country. We identified changes in the availability of individual patient demographic attributes over time and across clinical sites.ResultsSeveral attributes were consistently available over the study period (2005-2014) including last name (99.96%), first name (99.95%), date of birth (98.82%), gender/sex (99.73%), postal code (94.71%), and full street address (94.65%). Other attributes changed significantly from 2005-2014: Social security number (SSN) availability declined from 83.3% to 50.44% (p<0.0001). Email address availability increased from 8.94% up to 54% availability (p<0.0001). Work phone number increased from 20.61% to 52.33% (p<0.0001).ConclusionsOverall, first name, last name, date of birth, gender/sex and address were widely collected across institutional sites and over time. Availability of emerging attributes such as email and phone numbers are increasing while SSN use is declining. Understanding the relative availability of patient attributes can inform strategies for optimal matching in healthcare

Pharmacogenomic Variants May Influence the Urinary Excretion of Novel Kidney Injury Biomarkers in Patients Receiving Cisplatin

Nephrotoxicity is a dose limiting side effect associated with the use of cisplatin in the treatment of solid tumors. The degree of nephrotoxicity is dictated by the selective accumulation of cisplatin in renal tubule cells due to: (1) uptake by organic cation transporter 2 (OCT2) and copper transporter 1 (CTR1); (2) metabolism by glutathione S-transferases (GSTs) and γ-glutamyltransferase 1 (GGT1); and (3) efflux by multidrug resistance-associated protein 2 (MRP2) and multidrug and toxin extrusion protein 1 (MATE1). The purpose of this study was to determine the significance of single nucleotide polymorphisms that regulate the expression and function of transporters and metabolism genes implicated in development of acute kidney injury (AKI) in cisplatin treated patients. Changes in the kidney function were assessed using novel urinary protein biomarkers and traditional markers. Genotyping was conducted by the QuantStudio 12K Flex Real-Time PCR System using a custom open array chip with metabolism, transport, and transcription factor polymorphisms of interest to cisplatin disposition and toxicity. Traditional and novel biomarker assays for kidney toxicity were assessed for differences according to genotype by ANOVA. Allele and genotype frequencies were determined based on Caucasian population frequencies. The polymorphisms rs596881 (SLC22A2/OCT2), and rs12686377 and rs7851395 (SLC31A1/CTR1) were associated with renoprotection and maintenance of estimated glomerular filtration rate (eGFR). Polymorphisms in SLC22A2/OCT2, SLC31A1/CTRI, SLC47A1/MATE1, ABCC2/MRP2, and GSTP1 were significantly associated with increases in the urinary excretion of novel AKI biomarkers: KIM-1, TFF3, MCP1, NGAL, clusterin, cystatin C, and calbindin. Knowledge concerning which genotypes in drug transporters are associated with cisplatin-induced nephrotoxicity may help to identify at-risk patients and initiate strategies, such as using lower or fractionated cisplatin doses or avoiding cisplatin altogether, in order to prevent AKI
