Comparative Performance of Three Eye-Tracking Devices in Detection of Mild Traumatic Brain Injury in Acute Versus Chronic Subject Populations.

Introduction: Presently, traumatic brain injury (TBI) triage in field settings relies on symptom-based screening tools such as the updated Military Acute Concussion Evaluation. Objective eye-tracking may provide an alternative means of neurotrauma screening due to sensitivity to neurotrauma brain-health changes. Previously, the US Army Medical Research and Development Command Non-Invasive NeuroAssessment Devices (NINAD) Integrated Product Team identified 3 commercially available eye-tracking devices (SyncThink EYE-SYNC, Oculogica EyeBOX, NeuroKinetics IPAS) as meeting criteria toward being operationally effective in the detection of TBI in service members.

Anesthetic Management of a Patient With Eagle's Syndrome: A Case Study.

Eagle's syndrome is a condition characterized by elongation of the styloid process or calcification of the styloid ligament that can manifest as a constellation of symptoms including dysphagia, globus sensation, hoarseness, headache, and neck pain. Anatomically, this can impinge neurovascular structures, distort the hypopharynx, and stiffen the epiglottis and other pharyngeal structures, increasing the difficulty of airway management. The objective of this case study was to discuss the features of Eagle's syndrome and anesthetic considerations in the management of the condition.

Validity of Weekly and Monthly Perceived Exertion in Runners.

The development of the rating of perceived exertion (RPE) enables the easy assessment of runners' training strain as well as training load (TL). However, the long-term and retrospective validity of TL assessment using RPE scales still needs further investigation. Therefore, this study examined the validity of weekly and monthly ratings of perceived exertion (W-RPE, M-RPE) in assessing TL in runners.

Student loan debt and the career choices of college graduates with majors in the arts.

This study looks to test the impact of student loan debt on the career choices of college graduates with majors in the arts in the USA. As earnings are on average lower and more variable for arts graduates when compared to graduates of many other fields, I hypothesize that student loan debt will decrease the likelihood arts graduates will work in jobs related to their major fields of study. National Survey of College Graduates data is used to test this hypothesis.

Trilobite tridents demonstrate sexual combat at 400 Mya.

The Devonian trilobite carries a remarkable anterior cephalic trident posing a challenge to functional interpretation. A unique teratological specimen of showing four, rather than three tines, is inconsistent with possible hypotheses connecting the trident to feeding techniques and suggests a sexually selected function. Malformations in a variety of living organisms support this conclusion.

Chronic restraint stress increases sensitivity to punishment during cocaine self-administration via a dopamine D-like receptor-mediated mechanism in prelimbic medial prefrontal cortex.

We recently reported that male rats displayed less sensitivity to punishment during cocaine self-administration compared to females. Moreover, daily restraint stress increased sensitivity to punishment in males, while having no effect in females. The purpose of the present study was to extend these findings by determining whether chronic stress-induced dopamine release in prelimbic medial prefrontal cortex mediates the effect of stress on punished cocaine self-administration.

Ancient Lowland Maya neighborhoods: Average Nearest Neighbor analysis and kernel density models, environments, and urban scale.

Many humans live in large, complex political centers, composed of multi-scalar communities including neighborhoods and districts. Both today and in the past, neighborhoods form a fundamental part of cities and are defined by their spatial, architectural, and material elements. Neighborhoods existed in ancient centers of various scales, and multiple methods have been employed to identify ancient neighborhoods in archaeological contexts.

The benefits of rotating through palliative care: A qualitative study.

Purpose: This is a qualitative study of written reflection projects by medical learners who completed a clinical rotation in Palliative Care (PC) at an academic tertiary care center.

Methods: Upon completing their rotation in PC, medical learners were asked to complete an open-ended reflection project that captured their overall impressions of this training and experience. Fourteen reflections were coded and analyzed.

Sex-dependent effects of chronic stress on punished cocaine self-administration and cue-induced relapse to cocaine seeking.

We tested the effects of chronic stress on cocaine relapse after drug-reinforced responding was suppressed by punishment, an animal model of human relapse after self-imposed abstinence due to the negative consequences of drug use. Male rats displayed greater resistance to punishment than females, but daily stress decreased this resistance. Only female rats with a history of chronic stress displayed increased responding for cocaine cues from abstinence Day 1 to Day 8.

Incorporating medication therapy management into community pharmacy workflows.

Medication Therapy Management (MTM) is a group of pharmacist-provided services that optimize individual patients' drug therapy outcomes. Since community pharmacies' primary business platform is the dispensing of medications, and providing MTM services is a secondary source of revenue, pharmacies with limited resources are operationally challenged when trying to efficiently deliver both types of services. To address this problem, we follow a queueing network approach to develop an operational model of a community pharmacy workflow.

Reclaiming Family, Reimaging Queer Relationality.

Family is an important issue in imagining queer modes of existence. In this essay, I argue for a queer relationality that is structured around biogenetic family, a site that is often marginalized and negated in dominant Euro-American queer discourse. Informed by queer of color critique and postcolonial feminism, this essay affirms the relational framework in understanding the everyday struggles of queer subjects.

A novel methodology of international discourse: online joint course across cultures.

This article explores a novel methodology in the globalized classroom to face and tackle new challenges across cultures. The new online educational form of international discourse has the potential to make a difference in and outside Academia as it encompasses interpersonal communication across cultures and thus offers a novel framework for interpretation of different sociocultural perspectives to bring about social change. It transcends geographical and physical boundaries as it brings people together for discussion in the online joint event.

Intraoperative Transcranial Electrical Motor Evoked Potential (TceMEP) as a Therapeutic Tool in Spine Surgery: A Case Series Report.

We report two cases of unilateral loss of TceMEP secondary to spinal instrumentation errors and the subsequent recovery of TceMEP responses following prompt intervention. During the period of TceMEP loss, there were no concomitant SSEP changes beyond the threshold criteria. Postoperative physical examination revealed normal strength and motion in the affected extremities in both patients.

Prelimbic medial prefrontal cortex has bidirectional control over the expression of behavioral sensitization to 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) depending on the context of drug administration.

Behavioral sensitization to MDMA is observed in the vast majority of rats if tested in the same environment in which previous MDMA exposure occurred, but not if tested in a novel, unpaired context. Previous studies have revealed a critical role for the prelimbic region of medial prefrontal cortex (PL) in the expression of sensitization to MDMA, but these studies assessed sensitization only in MDMA-paired environments. Given that PL activity can both facilitate and suppress behavior depending on context, we tested the hypothesis that PL has bidirectional control over the expression of locomotor sensitization to MDMA depending on the context of drug administration.

A Self-management SMS Text Messaging Intervention for People With Inflammatory Bowel Disease: Feasibility and Acceptability Study.

Background: Mobile health technologies can be useful for providing disease self-management information and support to people with inflammatory bowel disease (IBD).

Objective: The aim of this study was to test a self-management SMS text messaging intervention for people with IBD. Our goal was to examine intervention feasibility, acceptability, and engagement and to preliminarily evaluate improvements in certain self-reported health outcomes among participants.

The Influence of L-menthol on Time Trial Running Performance in Recreational Runners.

This study investigated the effects of combined mouth rinse and topical application of L-menthol on perceptual responses and running performance under thermoneutral conditions (22 ± 2°C and 30-60% relative humidity). Twelve recreational male runners (age: 31.7 ± 3.

Is it reciprocating or self-serving?: Understanding coping strategies for postpartum depression in an online community for Korean mothers.

The proliferation of online health communities creates opportunities to exchange social support. Given the growing need to investigate the extent to which social support helps mothers with postpartum depression (PPD) and psychological distress, we conducted a content analysis of 3,073 posts from a PPD-related message board in a prominent online community for Korean mothers. We found that community members tended to provide rather than seek support, indicating potential reciprocity in the community.

The Effect of Microphone Frequency Response on Spectral and Cepstral Measures of Voice: An Examination of Low-Cost Electret Headset Microphones.

Purpose: The purpose of this study was to establish the frequency response of a selection of low-cost headset microphones that could be given to subjects for remote voice recordings and to examine the effect of microphone type and frequency response on key acoustic measures related to voice quality obtained from speech and vowel samples.

Method: The frequency responses of three low-cost headset microphones were evaluated using pink noise generated via a head-and-torso model. Each of the headset microphones was then used to record a series of speech and vowel samples prerecorded from 24 speakers who represented a diversity of sex, age, fundamental frequency ( ), and voice quality types.

Arts majors and the Great Recession: a cross-sectional analysis of educational choices and employment outcomes.

This study uses American Community Survey data to examine the impact of the Great Recession on college graduates majoring in the arts. Arts graduates play important roles in an economy, through both artistic creation and in careers outside of the arts. While the Great Recession took a significant toll on the US economy generally, arts majors faced additional vulnerabilities as industries that rely on discretionary spending, like the arts and entertainment, are especially hard hit in times of economic downturn.

Prevalence and Significance of Patient Prosthesis Mismatch Following Edwards SAPIEN XT and SAPIEN 3 Transcatheter Aortic Valve Replacement.

Background Severe patient prosthesis mismatch (sPPM) after surgical aortic valve replacement is associated with worse outcomes. Limited data exists on the impact of sPPM on outcomes after transcatheter aortic valve replacement (TAVR), especially regarding the newer generation valves. The aim of this study was to evaluate the incidence, determinants, and outcomes of sPPM in patients undergoing TAVR with Edwards SAPIEN XT (ES XT) and Edwards SAPIEN 3 (ES3) valves (Edwards Lifesciences, Irvine, CA, USA).

Effect of Test Sequence on Maximal Anaerobic and Aerobic Power Achievements in Adults.

The purpose of this study was to examine the effect of test sequence on adults' ability to achieve maximal aerobic and anaerobic power during a single assessment visit. Forty-one adults (24 men, 17 women; 22.0 ± 1.

Dopamine D-like receptors in prelimbic, but not infralimbic, medial prefrontal cortex contribute to chronic stress-induced increases in cue-induced relapse to palatable food seeking during forced abstinence.

Chronic stress exposure causes increased vulnerability to future relapse-like behavior in male, but not female, rats with a history of palatable food self-administration. These effects are mediated by dopamine D-like receptors, but the anatomical location of chronic stress' dopaminergic mechanism is not known. Thus, male rats were trained to respond for palatable food pellets in daily sessions.

Controlled (re)evaluation of the relationship between speech perception in noise and contralateral suppression of otoacoustic emissions.

In people with normal hearing (NH), speech perception in noise (SPIN) improves when the speech signal is presented not gated with noise but after a delay. The medial olivocochlear reflex (MOCR) was thought to be involved in the neural dynamic range adaptation (NDRA) responsible for this adaptive SPIN; however, some of the recent studies do not support this hypothesis and suggest that adaptive SPIN involves the NDRA to noise-level statistics, irrespective of MOCR activation. A plausible reason for this discrepancy could be the variations and limitations of the experimental designs used in different studies.
