Abstract Background We describe a 42-year-old patient with reported “shaking” vision referred due to concerns of possible vestibular system dysfunction. The patient has known history of Usher syndrome type I, bilateral cochlear implants, and severe vision impairment. Purpose This case describes an unusual nystagmus previously only reported in individuals with central demyelinating disorders, significant light deprivation, or in congenital/early-onset visual pathway impairment. Research Design Case study. Data Collection and Analysis Retrospective chart review of vestibular function. Results Vestibular function was likely absent in this case. There was no evidence of vestibular (jerk) nystagmus for sinusoidal harmonic acceleration stimuli or repeatable responses for cervical vestibular evoked myogenic potentials. Significant pendular low-amplitude high-frequency oscillations of approximately 6 Hz were present for horizontal and vertical tracings throughout testing. Conclusion Nystagmus may not always be associated with vestibular system impairment. In this case, the patient's reported “shaking” vision was attributed to pendular low-amplitude high-frequency nystagmus and hypothesized to relate to long-standing significant vision impairment. This presentation is unusual in adults and has historically been associated with individuals with significant central pathology or in those with long duration light deprivation.

Delirium is common in hospitalised patients, and there is currently no specific treatment. Identifying and treating underlying somatic causes of delirium is the first priority once delirium is diagnosed. Several international guidelines provide clinicians with an evidence-based approach to screening, diagnosis and symptomatic treatment. However, current guidelines do not offer a structured approach to identification of underlying causes. A panel of 37 internationally recognised delirium experts from diverse medical backgrounds worked together in a modified Delphi approach via an online platform. Consensus was reached after five voting rounds. The final product of this project is a set of three delirium management algorithms (the Delirium Delphi Algorithms), one for ward patients, one for patients after cardiac surgery and one for patients in the intensive care unit.

When students feel successful, they tend to be more confident in their capabilities (i.e., higher self-efficacy), which is associated with improved performance, engagement, and self-regulation. Yet, the way in which learners interpret their experiences is less well-understood. Learners’ views of failure (i.e., failure mindset) are potential lenses through which early adolescent learners perceive and interpret efficacy-relevant information. The relationship between failure mindset and self-efficacy may be particularly important to consider in STEM-related domains like robotics where failure is common. The purpose of this study was to investigate the relationship between young adolescents’ failure mindset and their robotics self-efficacy development. Using mixed methods, we considered how students’ reported failure mindset levels were related to what has made them more or less confident in robotics. We also considered the relationship between failure mindset and robotics self-efficacy. Overall, the findings suggest that early adolescent learners’ failure mindset is related to the efficacy-relevant information they pay attention to in robotics, and, in turn, is associated with their reported robotics self-efficacy. The details of these relationships varied between elementary and middle school students. As there is a social push to normalize failures in educational settings, findings from this study offer an important insight into how students may interpret those failures.

AbstractBACKGROUNDDelirium, a common syndrome with heterogeneous etiologies and clinical presentations, is associated with poor long‐term outcomes. Recording and analyzing all delirium equally could be hindering the field's understanding of pathophysiology and identification of targeted treatments. Current delirium subtyping methods reflect clinically evident features but likely do not account for underlying biology.METHODSThe Delirium Subtyping Initiative (DSI) held three sessions with an international panel of 25 experts.RESULTSMeeting participants suggest further characterization of delirium features to complement the existing Diagnostic and Statistical Manual of Mental Disorders Fifth Edition Text Revision diagnostic criteria. These should span the range of delirium‐spectrum syndromes and be measured consistently across studies. Clinical features should be recorded in conjunction with biospecimen collection, where feasible, in a standardized way, to determine temporal associations of biology coincident with clinical fluctuations.DISCUSSIONThe DSI made recommendations spanning the breadth of delirium research including clinical features, study planning, data collection, and data analysis for characterization of candidate delirium subtypes.Highlights Delirium features must be clearly defined, standardized, and operationalized. Large datasets incorporating both clinical and biomarker variables should be analyzed together. Delirium screening should incorporate communication and reasoning.

Abstract Background Engineering students encounter high levels of stress, which may negatively impact their mental health. Nevertheless, engineering students who experience mental health distress are less likely than their peers to seek professional help, even when controlling for gender and race/ethnicity. Purpose We examined beliefs that undergraduate engineering students have about barriers and facilitators to seeking professional help for their mental health. We also sought to identify cultural and systemic factors within and beyond engineering that might affect help‐seeking. Together, these beliefs influence students' sense of personal agency around seeking mental health care. Method We implemented a pragmatic qualitative design that incorporated the integrated behavioral model to investigate engineering students' ( N = 33) professional mental health help‐seeking beliefs. We used thematic analysis to analyze help‐seeking beliefs and perceived barriers and facilitators that students described during interviews. Results We identified four themes: Navigating the system impacts personal agency; sacrifices associated with help‐seeking act as a barrier; engineering culture acts as a barrier to help‐seeking; and student confidence in help‐seeking varies significantly. These themes portray the effect of perceived barriers and facilitators on students' personal agency for accessing mental health care. Our findings have implications for engineering departments and university counseling centers that want to minimize barriers to help‐seeking. Conclusions Engineering stakeholders must improve access to professional help for engineering students. Implementing changes to normalize help‐seeking behaviors, enhance personal agency, and facilitate engagement with mental health resources will create better conditions for engineers. Further research is necessary to understand how other beliefs (e.g., attitudes, perceived norms) inform the relationships between student mental health, professional help seeking, and engineering culture.

These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. All patients experience some level of distress associated with a cancer diagnosis and the effects of the disease and its treatment regardless of the stage of disease. Clinically significant levels of distress occur in a subset of patients, and identification and treatment of distress are of utmost importance. The NCCN Distress Management Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights describe updates to the NCCN Distress Thermometer (DT) and Problem List, and to the treatment algorithms for patients with trauma- and stressor-related disorders.

Our understanding of inner ear hair cell ultrastructure has heretofore relied upon two-dimensional imaging; however, serial block-face scanning electron microscopy (SBFSEM) changes this paradigm allowing for three-dimensional evaluation. We compared inner ear hair cells of the apical cristae in myo7aa −/− null zebrafish, a model of human Usher Syndrome type 1B, to hair cells in wild-type zebrafish by SBFSEM to investigate possible ribbon synapse ultrastructural differences. Previously, it has been shown that compared to wild type, myo7aa −/− zebrafish neuromast hair cells have fewer ribbon synapses yet similar ribbon areas. We expect the recapitulation of these results within the inner ear apical crista hair cells furthering the knowledge of three-dimensional ribbon synapse structure while resolving the feasibility of therapeutically targeting myo7aa −/− mutant ribbons. In this report, we evaluated ribbon synapse number, volume, surface area, and sphericity. Localization of ribbons and their distance from the nearest innervation were also evaluated. We determined that myo7aa −/− mutant ribbon synapses are smaller in volume and surface area; however, all other measurements were not significantly different from wild-type zebrafish. Because the ribbon synapses are nearly indistinguishable between the myo7aa −/− mutant and wild type, it suggests that the ribbons are structurally receptive, supporting that therapeutic intervention may be feasible.
