RESUMEN

INTRODUCTION/AIMS: Patients with amyotrophic lateral sclerosis (ALS) are susceptible to malnutrition, with appropriate management of nutritional interventions an active area of investigation. We sought to determine the impact of gastrostomy tube placement in ALS patients, exploring the correlation between forced vital capacity (FVC), malnutrition, and perioperative complications. METHODS: A retrospective review was performed of clinically diagnosed ALS patients treated at two multidisciplinary clinics (University of Kansas, University of Nebraska) from January 2009 to September 2020 who were referred for gastrostomy. Data collected included demographics, disease characteristics, and key gastrostomy related dates/outcomes. RESULTS: Two hundred thirty-nine patients were included with a median age of 65 years and median of 589 days from symptom onset to gastrostomy (interquartile range, 404-943). The population was predominantly Non-Hispanic White with bulbar-onset ALS. 30-day mortality was 4% and 30-day morbidity was 13%. Weight loss, body mass index, and predicted FVC at placement showed no increased 30-day morbidity or mortality association. Bulbar-onset ALS patients exhibited higher overall mortality postplacement than limb onset (odds ratio: 1.85, 95% confidence interval: 1.03-3.33). There was a 5% incidence of symptoms suggestive of refeeding syndrome. DISCUSSION: Rates of major/minor complications and 30-day mortality related to gastrostomy placement in our population were similar compared with prior studies in ALS. The lack of difference in outcomes based on FVC at procedure may suggest this is not predictive of outcome, or perhaps, high-quality perioperative respiratory management. Alternative reasons may account for the increased morbidity and mortality of gastrostomy placement in the ALS population.

RESUMEN

BACKGROUND: Advancements in arterial stenting technology have challenged prior notions favoring medical management for intracranial atherosclerotic disease (ICAD). Where previous conclusions were drawn from bare metal stent (BMS) technology, recent studies suggest drug-eluting stents (DES) are favorable due to their anti-proliferative effect, which reduces vascular remodeling. METHODS: We conducted a systematic review and meta-analysis of the literature prior to August 2023 reviewing all reports of ICAD treated with DES. Our target outcomes were incidence of any stroke, transient ischemic attack (TIA), or death within 30 days (postprocedural complications), ischemic stroke in the territory of the qualifying artery beyond 30 days (long-term complications), radiographically detected in-stent restenosis rate (ISR), and symptomatic ISR during follow-up. A subgroup analysis further stratified preprocedural mean stenosis above and below 70% into severe and moderate cohorts, respectively. RESULTS: PubMed, Web of Science, Cochrane and EMBASE query identified 527 candidate articles, from which 14 studies met inclusion criteria for a total of 607 patients and 640 ICAD lesions. Incidence of postprocedural complications was 7.3% (95% CI 3.9-11.7%) with subgroup analysis demonstrating significantly higher incidence in the severely stenotic group [9.0% (95% CI 4.7-14.5%)] than the moderately stenotic group [3.0% (95% CI 0.7-6.8%)]. Long-term complications were 1.2% (95% CI 0.4-2.3%). Radiographic ISR was 3.5% (95% CI 1.4-6.3%) and symptomatic ISR was 0.3% (95% CI 0.0-1.5%). CONCLUSIONS: Our systematic review and meta-analysis suggest that DES can effectively reduce the risk of ISR and may be a viable treatment modality to reduce long-term complications in refractory ICAD patients.

RESUMEN

Both the APOE ε4 and TOMM40 rs10524523 ("523") genes have been associated with risk for Alzheimer's disease (AD) and neuroimaging biomarkers of AD. No studies have investigated the relationship of TOMM40'523-APOE ε4 on the structural complexity of the brain in AD individuals. We quantified brain morphology and multiple cortical attributes in individuals with mild cognitive impairment (MCI) and AD, then tested whether APOE ε4 or TOMM40 poly-T genotypes were related to AD morphological biomarkers in cognitively unimpaired (CU) and MCI/AD individuals. We identified several AD-specific phenotypes in brain morphology and found that TOMM40 poly-T short alleles are associated with early, AD-specific brain morphological differences in healthy aging. We observed decreased cortical thickness, sulcal depth, and fractal dimension in CU individuals with the poly-T short alleles. Moreover, in MCI/AD participants, the APOE ε4 (TOMM40 L) individuals had a higher rate of gene-related morphological markers indicative of AD. Our data suggest that TOMM40'523 is associated with early brain structure variations in the precuneus, temporal, and limbic cortices.

RESUMEN

Background: The COVID-19 pandemic resulted in implementation of restrictive public health policies requiring people to limit or avoid interaction with others. These policies also had an economic impact. Individuals with multiple sclerosis (MS) already experience higher incidences of depression, anxiety, social isolation, and job loss, and the continuing pandemic may exacerbate these. Methods: Between November 2, 2020, and February 12, 2021, 233 individuals with MS completed the Hospital Anxiety and Depression Scale, the modified Medical Outcomes Study Social Support Survey, the Centers for Disease Control/National Institutes of Health Common Data Element Repository economic impact questions, and study team-designed questions about social and family relationships and adherence to public health policies. Results: Study participants reported high rates of mask wearing, good hand hygiene, and limited interactions with those outside their homes. They felt isolated from family they did not live with, friends, and coworkers. The frequency of conflicts with their spouses/partners increased "a little" among 20% of respondents, but overall relationships with housemates were "unchanged" or "a little better." Ninety-one percent of participants reported experiencing no financial impact. On the Hospital Anxiety and Depression Scale, 16.0% of 218 respondents reported depressive symptoms and 26.8% of 216 reported symptoms of anxiety above the commonly accepted clinically significant cutoff points. Only 3.4% of participants reported contracting SARS-CoV-2. Conclusions: During the first year of the pandemic, this study found no pronounced impact on the emotional, social, or economic stability of the individuals with MS it surveyed. It seems that these study participants adapted to the restrictions created by the pandemic and, by adhering to guidelines, protected themselves from contracting SARS-CoV-2.

RESUMEN

INTRODUCTION: Circulatory-respiratory death declaration is a common duty of physicians, but little is known about the amount of education and physician practice patterns in completing this examination. METHODS: An online survey of physicians was conducted evaluating the rate of formal training and specific examination techniques used in the pronouncement of circulatory-respiratory death. Data, including the level of practice, training received in a formal death declaration, and examination components, were collected. RESULTS: Respondents were attending physicians (52.4%), residents (30.2%), fellows (10.7%), and interns (6.7%). Most respondents indicated they had received no formal training in death pronouncement; however, most reported self-perceived competence. When comparing examination components used by the study's cohort, 95 different examination combinations were used for death pronouncement. CONCLUSIONS: Formal training in death pronouncement was uncommon and clinical practice varied. Implementation of formal training and standardization of the examination are necessary to improve physician competence and reliability in death declarations.

RESUMEN

Background: Pharmacy administrative claims data remain an accessible and efficient source to measure medication adherence for frequently hospitalized patient populations that are systematically excluded from the landmark drug trials. Published pharmacotherapy studies use medication possession ratio (MPR) and proportion of days covered (PDC) to calculate medication adherence and usually fail to incorporate hospitalization and prescription overlap/gap from claims data. To make the cacophony of adherence measures clearer, this study created a refined hospital-adjusted algorithm to capture pharmacotherapy adherence among patients with end-stage renal disease (ESRD). Methods: The United States Renal Data System (USRDS) registry of ESRD was used to determine prescription-filling patterns of those receiving new prescriptions for oral P2Y12 inhibitors (P2Y12-I) between 2011 and 2015. P2Y12-I-naïve patients were followed until death, kidney transplantation, discontinuing medications, or loss to follow-up. After flagging/censoring key variables, the algorithm adjusted for hospital length of stay (LOS) and medication overlap. Hospital-adjusted medication adherence (HA-PDC) was calculated and compared with traditional MPR and PDC methods. Analyses were performed with SAS software. Results: Hospitalization occurred for 78% of the cohort (N = 46 514). The median LOS was 12 (interquartile range [IQR] = 2-34) days. MPR and PDC were 61% (IQR = 29%-94%) and 59% (IQR = 31%-93%), respectively. After applying adjustments for overlapping coverage days and hospital stays independently, HA-PDC adherence values changed in 41% and 52.7% of the cohort, respectively. When adjustments for overlap and hospital stay were made concurrently, HA-PDC adherence values changed in 68% of the cohort by 5.8% (HA-PDC median = 0.68, IQR = 0.31-0.93). HA-PDC declined over time (3M-6M-9M-12M). Nearly 48% of the cohort had a ≥30 days refill gap in the first 3 months, and this increased over time (P < .0001). Conclusions: Refill gaps should be investigated carefully to capture accurate pharmacotherapy adherence. HA-PDC measures increased adherence substantially when adjustments for hospital stay and medication refill overlaps are made. Furthermore, if hospitalizations were ignored for medications that are included in Medicare quality measures, such as Medicare STAR program, the apparent reduction in adherence might be associated with lower quality and health plan reimbursement.

RESUMEN

INTRODUCTION: Although oral P2Y12 inhibitors (P2Y12-Is) are one of the most commonly prescribed medication classes in patients with end stage kidney disease on dialysis (ESKD), scarce data exist regarding their benefits and risks. METHODS: We compared effectiveness and safety of clopidogrel, prasugrel, and ticagrelor in a longitudinal study using the United States Renal Data System registry of Medicare beneficiaries with ESKD. Individuals who filled new P2Y12-I prescriptions between 2011 and 2015 were included and followed until death or censoring. The primary exposure variable was P2Y12-I assignment. The primary outcome variable was death. Secondary outcomes included cardiovascular (CV) death, coronary revascularization, and gastrointestinal (GI) hemorrhage. Survival analyses were performed after propensity matching. RESULTS: Of 44,619 patients with ESKD who received P2Y12-Is, 95% received clopidogrel (n = 42,523), 3% prasugrel (n = 1205), and 2% ticagrelor (n = 891). To balance baseline differences, propensity-matching was performed: 1:6 for prasugrel (n = 1189) versus clopidogrel (n = 7134); 1:4 for ticagrelor (n = 880) versus clopidogrel (n = 3520); and 1:1 for ticagrelor versus prasugrel (n = 880). Prasugrel was associated with a reduced risk for death versus clopidogrel and ticagrelor (adjusted hazard ratio [HR] = 0.82; 95% CI: 0.73-0.93 and 0.78; 95% CI: 0.64-0.95). Compared with clopidogrel, prasugrel reduced risk for coronary revascularization (HR = 0.91; 95% CI: 0.86-0.96). There were no differences in GI hemorrhage between P2Y12-Is. CONCLUSION: In patients with ESKD, prasugrel compared with others reduced risk of death possibly by reducing risk for coronary revascularizations and without worsening gastrointestinal hemorrhage. Future trials are imperative to compare efficacy and safety of P2Y12-Is in patients with ESKD.

RESUMEN

BACKGROUND: The University of Kansas Alzheimer's Disease Center (KU ADC) maintains several large databases to track participant recruitment, enrollment, and capture various research-related activities. It is challenging to manage and coordinate all the research-related activities. One of the crucial activities involves generating a consensus diagnosis and communicating with participants and their primary care providers. PROCESS: To effectively manage the cohort, the KU ADC utilizes a combination of open-source electronic data capture (EDC) (i.e. REDCap), along with other homegrown data management and analytic systems developed using R-studio and Shiny. PROCESS EVALUATION: In this article, we describe the method and utility of the user-friendly dashboard that was developed for the rapid reporting of dementia evaluations which allows clinical researchers to summarize recruitment metrics, automatically generate letters to both participants and healthcare providers, which ultimately help optimize workflows. CONCLUSIONS: We believe this general framework would be beneficial to any institution that build reports and summarizing key metrics of their research from longitudinal databases.

RESUMEN

BACKGROUND: Our goal was to investigate the role of physical exercise to protect brain health as we age, including the potential to mitigate Alzheimer's-related pathology. We assessed the effect of 52 weeks of a supervised aerobic exercise program on amyloid accumulation, cognitive performance, and brain volume in cognitively normal older adults with elevated and sub-threshold levels of cerebral amyloid as measured by amyloid PET imaging. METHODS AND FINDINGS: This 52-week randomized controlled trial compared the effects of 150 minutes per week of aerobic exercise vs. education control intervention. A total of 117 underactive older adults (mean age 72.9 [7.7]) without evidence of cognitive impairment, with elevated (n = 79) or subthreshold (n = 38) levels of cerebral amyloid were randomized, and 110 participants completed the study. Exercise was conducted with supervision and monitoring by trained exercise specialists. We conducted 18F-AV45 PET imaging of cerebral amyloid and anatomical MRI for whole brain and hippocampal volume at baseline and Week 52 follow-up to index brain health. Neuropsychological tests were conducted at baseline, Week 26, and Week 52 to assess executive function, verbal memory, and visuospatial cognitive domains. Cardiorespiratory fitness testing was performed at baseline and Week 52 to assess response to exercise. The aerobic exercise group significantly improved cardiorespiratory fitness (11% vs. 1% in the control group) but there were no differences in change measures of amyloid, brain volume, or cognitive performance compared to control. CONCLUSIONS: Aerobic exercise was not associated with reduced amyloid accumulation in cognitively normal older adults with cerebral amyloid. In spite of strong systemic cardiorespiratory effects of the intervention, the observed lack of cognitive or brain structure benefits suggests brain benefits of exercise reported in other studies are likely to be related to non-amyloid effects.

RESUMEN

BACKGROUND: About 50% of all hospitalized fragility fracture cases in older Americans are hip fractures. Approximately 3/4 of fracture-related costs in the USA are attributable to hip fractures, and these are mostly covered by Medicare. Hip fracture patients with dementia, including Alzheimer's disease, have worse health outcomes including longer hospital length of stay (LOS) and charges. LOS and hospital charges for dementia patients are usually higher than for those without dementia. Research describing LOS and acute care charges for hip fractures has mostly focused on these outcomes in trauma patients without a known pre-admission diagnosis of osteoporosis (OP). Lack of documented diagnosis put patients at risk of not having an appropriate treatment plan for OP. Whether having a diagnosis of OP would have an effect on hospital outcomes in dementia patients has not been explored. We aim to investigate whether having a diagnosis of OP, dementia, or both has an effect on LOS and hospital charges. In addition, we also report prevalence of common comorbidities in the study population and their effects on hospital outcomes. METHODS: We conducted a cross-sectional analysis of claims data (2012-2013) for 2175 Medicare beneficiaries (≥65 years) in the USA. RESULTS: Compared to those without OP or dementia, patients with demenia only had a shorter LOS (by 5%; P = .04). Median LOS was 6 days (interquartile range [IQR]: 5-7), and the median hospital charges were $45,100 (IQR: 31,500 - 65,600). In general, White patients had a shorter LOS (by 7%), and those with CHF and ischemic heart disease (IHD) had longer LOS (by 7 and 4%, respectively). Hospital charges were 6% lower for women, and 16% lower for White patients. CONCLUSION: This is the first study evaluating LOS in dementia in the context of hip fracture which also disagrees with previous reporting about longer LOS in dementia patients. Patients with CHF and IHD remains at high risk for longer LOS regardless of their diagnosis of dementia or OP.

RESUMEN

PURPOSE: Class rank and clerkship grades impact a medical student's residency application. The variability and inter-rater reliability in assessment across multiple clinical sites within a single university system is unknown. We aimed to determine if medical student assessment across medical school campuses is consistent when using a standardized scoring rubric. DESIGN/METHODS: Attending physicians who participate in assignment of clerkship grades for neurology from three separate clinical campuses of the same medical school observed 10 identical standardized patient encounters completed by third year medical students during the 2017-2018 academic year. Scoring was completed using a standardized rubric. Descriptive analysis and intra-rater comparisons were completed. Evaluations as a part of this study were completed in 2018. RESULTS: Of 50 possible points for the patient encounter, the median score among all medical students and all evaluators was 43 (IQR 40, 45.5). Evaluator number 1 provided a statistically significant lower overall score as compared to evaluators 2 and 3 (p = 0.0001 and p = 0.0006, respectively), who were consistently similar in their overall medical student assessment (p = 0.46). Overall agreement between evaluators was good (ICC = 0.805, 95% CI 0.36-0.95) and consistency was excellent (ICC = 0.91, 95% CI 0.75-0.97). CONCLUSIONS: Medical student evaluation across multiple clinical campus sites via observation of identical standardized patient encounters and use of a standardized scoring rubric generally demonstrated good inter-rater agreement and consistency, but the small variation seen may affect overall clerkship scores.

RESUMEN

BACKGROUND: Trends and clinical factors associated with prescribing choices for oral P2Y12 inhibitors (P2Y12-I) remain unknown for patients on chronic dialysis, i.e., with end-stage renal disease (ESRD). METHODS: From 2011-2014 U.S. Renal Data System registry, we identified 36,542 ESRD patients who received new prescriptions for P2Y12-I (median age 64.0 years and 54% males). Of the cohort, 93% were receiving hemodialysis and 7% on peritoneal dialysis. We analyzed trends and investigated clinical factors associated with specific P2Y12-I prescribed. RESULTS: Clopidogrel was prescribed for 95%, prasugrel for 3%, and ticagrelor for 2%. Clopidogrel was favored for those ≥75 years (18% of cohort). Compared to Caucasians, African Americans (36% of cohort) and Hispanics (19% of cohort) were less likely to receive prasugrel and ticagrelor (P<0.05). Patients receiving hemodialysis versus peritoneal dialysis were less likely to receive prasugrel over clopidogrel, adjusted odds ratio (aOR) 0.67 (0.55-0.82). Each additional year of dialysis decreased the odds of receiving prasugrel over clopidogrel, aOR 0.91 (0.85-0.98). History of atrial fibrillation reduced the odds of receiving ticagrelor or prasugrel over clopidogrel, aOR 0.69 (0.54-0.89) and 0.73 (0.60-0.89), respectively. Concomitant oral anticoagulant use was not associated with choice of P2Y12-I. Occurrence of non-ST segment elevation myocardial infarction or percutaneous coronary intervention within the 6-month period prior to the index date favored ticagrelor over prasugrel, aOR 1.31 (1.06-1.62) and 1.29 (1.01-1.66), respectively. However, prescribing trends favoring ticagrelor over prasugrel were not observed for deployment of drug-eluting, or multiple coronary stents. CONCLUSION: Between 2011 and 2014, clopidogrel remained the most common P2Y12-I whereas ticagrelor and prasugrel remained underutilized in ESRD patients. Prescribing practices for these drugs were based upon clinically approved indication for their use in the general population as well as perceived complexity of an ESRD patient including demographics, dialysis-related factors and comorbidities. Comparative effectiveness studies involving ESRD patients are needed to prove that ticagrelor and prasugrel are just as safe and effective as clopidogrel before clinicians can make informed decisions for choice of P2Y12-I in this patient population.

RESUMEN

OBJECTIVE: Hook of hamate fracture, the most common swing-related wrist fracture, is commonly seen in high-level athletes. The fracture is rarely diagnosed on routine wrist radiographs, thus generally requiring CT or MR for diagnosis. Surgical excision has a high success rate, however diagnostic delay contributes to a high complication rate. Radiographic signs of hook of hamate fracture have been published, but uncertainty of the diagnostic accuracy limits application. The purpose of this study is to determine accuracy and interobserver reliability of radiographic signs of hook of hamate. MATERIALS AND METHODS: This retrospective case-control study evaluated wrist radiographs of 50 patients, including 24 positive and 26 negative, for hook of hamate fracture, each proven by CT or MR. Five reviewers performed blinded, randomized evaluation of radiographs documenting whether the hook of hamate was normal or fractured, and if fractured, the radiographic signs present (ring sign, ghostly shadow, and diffuse sclerosis) and views that contributed to diagnosis. RESULTS: Radiographic signs demonstrated high sensitivity (85%; 95% CI: 77-91), specificity (92%; 95% CI: 86-96), and accuracy (89%; 95% CI: 84-92) with substantial interobserver reliability (k = 0.652). The ring sign was the most sensitive radiographic sign. Diagnosis was most often supported by the oblique view (38%) and rarely the lateral view (15%). CONCLUSIONS: Radiographic signs of hook of hamate fracture on routine radiographs can accurately and reliably diagnose hook of hamate fractures. Evaluation for discontinuity of the cortical ring will optimize sensitivity, allowing for timely diagnosis and treatment, and a reduction of complications.

RESUMEN

RATIONALE AND OBJECTIVES: Adverse reactions to intravenous contrast for radiologic examinations can result in significant patient morbidity and mortality. It is critical that radiologists be proficient at recognizing and treating reactions in a timely and appropriate manner. Therefore, we developed a hands-on simulation curriculum to improve residents' ability and comfort in recognizing and responding to contrast reactions. MATERIALS AND METHODS: Contrast reaction management simulations were performed in 2016 and 2017 with 25 and 26 resident participants, respectively. Participants completed pre- and postsimulation surveys both years to assess knowledge and comfort in managing contrast reactions. RESULTS: In 2016, 25 participants answered 12 questions assessing knowledge of contrast reaction management. Percentage of correct answers increased from pre- to postsurvey in 83% of questions (10/12). Participants indicated their comfort level in managing contrast reactions increased on all six questions from pre- to postsurvey. In 2017, 26 participants answered 14 questions assessing knowledge of contrast reaction management. Similarly, percentage of correct answers increased from pre- to postsurvey in 86% of questions (12/14). Participant comfort levels also increased on all six questions from pre- to postsurvey. Subgroup analysis performed on 19 participants who completed the curriculum both years demonstrated further improvement in knowledge and comfort after completing the second year, showing added benefit of repeated simulation. CONCLUSION: These results suggest that incorporating high-fidelity contrast reaction management simulation into resident education improves both residents' knowledge and comfort in managing reactions. We have therefore incorporated annual contrast reaction simulation as a standard component of our residency curriculum.

RESUMEN

RATIONALE AND OBJECTIVES: To evaluate radiologic and pathologic features associated with upgrade of atypical ductal hyperplasia (ADH) to ductal carcinoma in situ or invasive breast cancer at surgical excision, in order to identify patients who may consider alternatives to excision. MATERIALS AND METHODS: This retrospective analysis examined patients who underwent surgical excision of biopsy-proven ADH at our institution. Imaging and pathology from biopsy were reviewed to determine radiologic (lesion size, radiologic abnormality, biopsy type, needle gauge, number of cores, percent of lesion removed) and pathologic features (histologic calcifications, presence of necrosis, micropapillary features, extent of ADH) associated with ADH upgrade. RESULTS: One hundred twenty four cases of percutaneous biopsy-proven ADH with subsequent excision were included. The overall upgrade rate was 17.7% (n = 22), with 17 cases to ductal carcinoma in situ and five to invasive cancer. Radiologic features associated with a lower upgrade rate were smaller lesion size (p = 0.032) and larger percent of lesion removed at biopsy (p = 0.047). Larger needle gauge at biopsy (p = 0.070), absence of necrosis (p = 0.051) and focal ADH (<3 foci, p = 0.12) were nearly associated with a lower rate of upgrade and were included for the purpose of multi parameter analyses. CONCLUSION: For women with ADH identified on percutaneous biopsy, the risk of upgrade may in part be determined by lesion size, percent of lesion removed at biopsy, presence of necrosis, and extent of ADH. Using a combination of these radiographic and pathologic features to stratify patients with biopsy-proven ADH may help identify women who could be considered for alternative treatment options.

RESUMEN

OBJECTIVE: Managing registries with continual data collection poses challenges, such as following reproducible research protocols and guaranteeing data accessibility. The University of Kansas (KU) Alzheimer's Disease Center (ADC) maintains one such registry: Curated Clinical Cohort Phenotypes and Observations (C3PO). We created an automated and reproducible process by which investigators have access to C3PO data. MATERIALS AND METHODS: Data was input into Research Electronic Data Capture. Monthly, data part of the Uniform Data Set (UDS), that is data also collected at other ADCs, was uploaded to the National Alzheimer's Coordinating Center (NACC). Quarterly, NACC cleaned, curated, and returned the UDS to the KU Data Management and Statistics (DMS) Core, where it was stored in C3PO with other quarterly curated site-specific data. Investigators seeking to utilize C3PO submitted a research proposal and requested variables via the publicly accessible and searchable data dictionary. The DMS Core used this variable list and an automated SAS program to create a subset of C3PO. RESULTS: C3PO contained 1913 variables stored in 15 datasets. From 2017 to 2018, 38 data requests were completed for several KU departments and other research institutions. Completing data requests became more efficient; C3PO subsets were produced in under 10 seconds. DISCUSSION: The data management strategy outlined above facilitated reproducible research practices, which is fundamental to the future of research as it allows replication and verification to occur. CONCLUSION: We created a transparent, automated, and efficient process of extracting subsets of data from a registry where data was changing daily.

RESUMEN

The Centers for Disease Control (CDC) declares exercise to be one of the most important activities one can do to improve health. The benefits of exercise are well documented and include both physiologic and psychological health. Given the current landscape of wellness issues in veterinary medical education, it is necessary that students engage in exercise activities to manage stress and increase overall health. Therefore, to develop targeted interventions with the greatest likelihood for success, it is first necessary to understand what motivates veterinary medical students to exercise given their unique situational and environmental factors. This study is the first to explore this issue systematically in veterinary medical education, thus it is the authors' hope that the findings from this research will help identify exercise-related wellness interventions that could be implemented in veterinary medical schools.

RESUMEN

Healthy eating is a challenge for most college students, and students in the field of veterinary medicine are no exception. Health experts have recommended that universities emphasize the importance of healthy eating and promote healthy eating habits among students. However, before we can begin offering targeted interventions to promote healthy eating strategies and behaviors, we must first understand students' current strategies used for making healthy eating choices, self-reported eating habits, and perceptions of diet quality. Thus, the purpose of this study was to understand veterinary medical students' perceptions of current diet quality and to characterize their strategies for making healthy eating choices. Results indicate veterinary medical students employ a wide range of strategies and behaviors for healthy eating, yet few students reported eating a diet of poor quality. We conclude that while most students report eating a relatively healthy diet, variation in strategies used suggests room for improvement for many. This article discusses potential intervention strategies to promote healthy eating among veterinary students.

RESUMEN

Increasing radiologic exam volume and complexity necessitates leveraging advanced hardware solutions to optimize workflow efficiency. We evaluated radiologist satisfaction of a programmable 13-button non-conventional mouse compared to a conventional three-button mouse in daily interpretation workflow following a brief 2-day trial period. A prospective study was conducted with radiology staff and residents in a tertiary care center from 2015 to 2016. A survey was distributed prior to and after a tutorial and a 2-day non-conventional mouse trial period. The post-survey evaluated usage time, device settings, satisfaction, preferences, and perceived efficiency of both mice. Descriptive analyses, correlations, the Sign test, and the Wilcoxon signed-rank test were used to evaluate responses. Fifty-nine participants completed pre- and post-surveys. Several (41%, n = 24) had prior experience with a non-conventional mouse. Prior to the trial, one third of all participants (35.6%, n = 21) reported being satisfied or very satisfied with their conventional mouse. After spending an average of 9.8 h using the non-conventional mouse, there were no statistically significant changes in overall satisfaction with either conventional or non-conventional mice (p = 0.84 and p = 0.39, respectively). However, 76.3% (n = 45) agreed/somewhat agreed they preferred to use the non-conventional mouse in their daily workflow as opposed to the conventional mouse. The non-conventional mouse was also perceived as more efficient (66.1%, n = 39), required less time (62.7%, n = 37) and effort (74.6%, n = 44) to view images, allowed for easier manipulation of windows/images (76.3%, n = 45), and was more comfortable to use (78.0%, n = 46). Although there were no statistically significant shifts in overall satisfaction, participants reported a higher level of satisfaction, perceived efficiency, and preference for a non-conventional 13-button mouse compared to a conventional three-button mouse following a brief, 2-day trial period.

RESUMEN

OBJECTIVE: The objective of this study was to better understand veterinary medical students' sleep hygiene and identify the extent to which sleep hygiene behaviors may result in consequences (either positive or negative) for students. SAMPLE: A total of 187 doctor of veterinary medicine (DVM) program students at a large College of Veterinary Medicine in the United States. METHODS: The Epworth Sleep Scale and Daytime Sleepiness Scale were administered to 393 students enrolled in the DVM program. RESULTS: About 55.1% of students reported <7 h of sleep per night, 28.9% reported having trouble sleeping, and 50.3% reported feeling sleepy all day. With respect to sleep quality, 5.3% described it as excellent, 52.4% as good, 34.2% as fair, and 8.0% as poor. CONCLUSIONS: A significant percentage of veterinary medical students exhibit poor sleep hygiene habits that may be detrimental to both their health and academic endeavors.
