Transcranial Doppler Ultrasound and Concussion-Supplemental Symptoms with Physiology: A Systematic Review.

Sport-related concussion (SRC) can impair the cerebrovasculature both acutely and chronically. Transcranial Doppler (TCD) ultrasound assessment has the potential to illuminate the mechanisms of impairment and provide an objective evaluation of SRC. The current systematic review investigated studies employing TCD ultrasound assessment of intracranial arteries across three broad categories of cerebrovascular regulation: neurovascular coupling (NVC), cerebrovascular reactivity (CVR), and dynamic cerebral autoregulation (dCA).

Adolescent Sport-Related Concussion and the Associated Neurophysiological Changes: A Systematic Review.

Background: Sport-related concussion (SRC) has been shown to induce cerebral neurophysiological deficits, quantifiable with electroencephalography (EEG). As the adolescent brain is undergoing rapid neurodevelopment, it is fundamental to understand both the short- and long-term ramifications SRC may have on neuronal functioning. The current systematic review sought to amalgamate the literature regarding both acute/subacute (≤28 days) and chronic (>28 days) effects of SRC in adolescents via EEG and the diagnostic accuracy of this tool.

Use of Biostatistical Models to Manage Replicate Error in Concussion Biomarker Research.

Importance: Advancing research on fluid biomarkers associated with sport-related concussion (SRC) highlights the importance of detecting low concentrations using ultrasensitive platforms. However, common statistical practices may overlook replicate errors and specimen exclusion, emphasizing the need to explore robust modeling approaches that consider all available replicate data for comprehensive understanding of sample variation and statistical inferences.

Objective: To evaluate the impact of replicate error and different biostatistical modeling approaches on SRC biomarker interpretation.

Role of biomarkers and emerging technologies in defining and assessing neurobiological recovery after sport-related concussion: a systematic review.

Objective: Determine the role of fluid-based biomarkers, advanced neuroimaging, genetic testing and emerging technologies in defining and assessing neurobiological recovery after sport-related concussion (SRC).

Design: Systematic review.

Data Sources: Searches of seven databases from 1 January 2001 through 24 March 2022 using keywords and index terms relevant to concussion, sports and neurobiological recovery.

Characterizing Factors Influencing Baseline Plasma Biomarkers for Sport-Related Concussion in Adolescents.

Developing objective measures to diagnose sport-related concussion (SRC) is a top priority, particularly in the pediatric context, given the vulnerability of the developing brain. While advances in SRC blood biomarkers are being made in adult populations, less data are available for adolescents. Clinical validation of blood biomarkers post-SRC will first require investigation in a healthy uninjured state.

Vaccine Inequities and the Legacies of Colonialism: Speculative Fiction's Challenge to Medicine.

New vaccines to prevent COVID-19 and malaria underscore the importance of scientific advances to promote public health globally. How is credit for such scientific discoveries attributed, and who benefits? The complex narrative of Amitav Ghosh's The Calcutta Chromosome, both historical and speculative, demonstrates how medicine has come to value particular kinds of advances over others, prompting readers to question who controls access to resources and at what cost to global populations. In Ghosh's imagined world, scientific discovery is evaluated and rewarded-and ultimately deemed necessary-for its ability to serve communal, public health needs.

Adjusting to Changing Environments: Virtual Preseason SCAT5 Assessment in Canadian Male Youth Football Players.

Objective: To provide preseason reference scores for Canadian youth tackle football players on the Sport Concussion Assessment Tool 5 (SCAT5) and to examine whether age, concussion history, and self-reported medical diagnoses are associated with SCAT5 subcomponent performance.

Design: Cross-sectional study.

Setting: Calgary, Alberta.

What affected UK adults' adherence to medicines during the COVID-19 pandemic? Cross-sectional survey in a representative sample of people with long-term conditions.

Aim: Medicines non-adherence is associated with poorer outcomes and higher costs. COVID-19 affected access to healthcare, with increased reliance on remote methods, including medicines supply. This study aimed to identify what affected people's adherence to medicines for long-term conditions (LTCs) during the pandemic.

Addressing multilevel barriers to clinical trial participation among Black and White men with prostate cancer through the PACCT study.

Background: Cancer clinical trial participation is low and inequitable. Partnering Around Cancer Clinical Trials (PACCT) addressed systemic and interpersonal barriers through an observational study of eligibility and an intervention to improve patient-physician communication and trial invitation rates.

Methods: Physicians at two comprehensive cancer centers and Black and White men with prostate cancer participated.

Results of an African American-targeted norm-based colorectal cancer screening intervention: a pilot study.

Lower colorectal cancer screening rates among African Americans contribute to higher colorectal cancer incidence and mortality. We tested the effects of a racially-targeted messaging intervention that used favorable behavioral norm information to increase uptake of at-home Fecal Immunochemical Test (FIT) Kits. We expected stronger intervention effects among African Americans with stronger racial identity.

Nonverbal Synchrony: An Indicator of Clinical Communication Quality in Racially-Concordant and Racially-Discordant Oncology Interactions.

Objectives: The aim of this cross-sectional study was to apply a novel software to measure and compare levels of nonverbal synchrony, as a potential indicator of communication quality, in video recordings of racially-concordant and racially-discordant oncology interactions. Predictions include that the levels of nonverbal synchrony will be greater during racially-concordant interactions than racially-discordant interactions, and that levels of nonverbal synchrony will be associated with traditional measures of communication quality in both racially-concordant and racially-discordant interactions.

Design: This is a secondary observational analysis of video-recorded oncology treatment discussions collected from 2 previous studies.

Does coprescribing nonsteroidal anti-inflammatory drugs and oral anticoagulants increase the risk of major bleeding, stroke and systemic embolism?

Aims: To examine the risk of gastrointestinal (GI) bleeding, major bleeding, stroke and systemic embolism associated with prescribing nonsteroidal anti-inflammatory drugs (NSAIDs) to adults receiving oral anticoagulant (OAC) therapy.

Methods: We conducted a population-based cohort study in adults receiving OAC therapy using linked primary care (Clinical Practice Research Datalink GOLD) and hospital (Hospital Episodes Statistics) electronic health records. We used cause-specific Cox regression models with time-dependent NSAID treatment in a propensity score matched population to estimate the increased risk of GI bleeding, stroke, major bleeding and systemic embolism associated with NSAID use.

Moderators of the effects of perceived racism and discrimination on cancer-related health behaviors among two samples of African Americans.

Background: Assumptions regarding within-race variation in the associations between measures of discrimination racism and health-related behaviors among African Americans have been largely unexplored.

Methods: We conducted secondary analyses of two studies to examine support for a model which describes several theoretical moderators of the effects of discrimination and racism on health behaviors. The first study examined the effects of group-based behavioral information and racial identity on the association between perceived racism and requests for at home colorectal cancer screening tests among a sample of 205 geographically diverse African Americans who participated in an online experiment from 2019 to 2020.

Development and pilot test of a physician-focused cancer clinical trials communication training intervention.

Objective: We describe the development and pilot test of a physician-focused, web-based training module designed to improve physician communication related to clinical trials in a diverse cancer patient population.

Methods: Researchers and stakeholders developed the training module, which included a video explaining patient-centered communication strategies for discussing trials, and re-enactments of actual clinical interactions. For the pilot test, the module was provided to physician participants in the Partnering Around Cancer Clinical Trials (PACCT) trial at two major urban cancer centers.

Long-term heart transplant recipients: heart rate-related effects on augmented transfer function coherence during repeated squat-stand maneuvers in males.

Previous research has highlighted that squat-stand maneuvers (SSMs) augment coherence values within the cerebral pressure-flow relationship to ∼0.99. However, it is not fully elucidated if mean arterial pressure (MAP) leads to this physiological entrainment independently, or if heart rate (HR) and/or the partial pressure of carbon dioxide (Pco) also have contributing influences.

A Review of Research on Disparities in the Care of Black and White Patients With Cancer in Detroit.

Racial disparities in cancer incidence and outcomes are well-documented in the US, with Black people having higher incidence rates and worse outcomes than White people. In this review, we present a summary of almost 30 years of research conducted by investigators at the Karmanos Cancer Institute's (KCI's) Population Studies and Disparities Research (PSDR) Program focusing on Black-White disparities in cancer incidence, care, and outcomes. The studies in the review focus on individuals diagnosed with cancer from the Detroit Metropolitan area, but also includes individuals included in national databases.

Mechanics of the Jump Shot: The "Dip" Increases the Accuracy of Elite Basketball Shooters.

The present study assessed the mechanics of the basketball jump shot to determine whether or not the "dip" increased shot accuracy. There remained a debate between coaches who believed "dipping" was too slow and coaches who believed "dipping" increased accuracy. A mixed design was used for the present study with elite high-school and university players all performing shots with and without the "dip" at four distances: the last hash mark before the free throw line (3.

Applied Racial/Ethnic Healthcare Disparities Research Using Implicit Measures.

Many healthcare disparities studies use the Implicit Association Test (IAT) to assess bias. Despite ongoing controversy around the IAT, its use has enabled researchers to reliably document an association between provider implicit prejudice and provider-to-patient communication (provider communication behaviors and patient reactions to them). Success in documenting such associations is likely due to the outcomes studied, study settings, and data structure unique to racial/ethnic healthcare disparities research.

Reducing Unnecessary Noninvasive Testing for Inpatients With Unstable Angina: The RUNIT Protocol.

Background: Routine inpatient transthoracic echocardiography (TTE) for patients with unstable angina is common, but it anecdotally adds little value to clinical care. A practice audit at our academic hospital demonstrated that 61.5% of patients with troponin-negative chest pain (TNCP) had normal left ventriculography (LVG) during coronary angiography and normal TTE on the same admission (duplicate testing).
