Understanding Abnormal Examination Findings During Concussion Recovery: A Retrospective Chart Review.

Background and Objective: Physical examination findings in athletes with sport-related concussion (SRC) are not well described in the literature. The objective of this study was to describe physical examination findings during the first month following concussion in athletes, with a focus on the effect of sex, age, and time since injury. Methods: This was a retrospective electronic medical record (EMR) review of physical examination findings in 500 patients aged 6-24 who were initially seen within 15 days of SRC at a multidisciplinary outpatient academic concussion clinic between 2017 and 2019. A standardized concussion examination built in the EMR recorded mental status, cranial nerve, vestibulo-ocular motor screen, and balance findings for all patients. The primary outcome was the frequency of abnormal examination findings during the first 30 days postinjury, which was further analyzed by sex, age, and time since injury using mixed logistic regression models. Results: The most common abnormal examination findings overall were eyes-closed single-leg stance, vestibular-ocular reflex, visual motion sensitivity, the neck examination, and eyes-closed tandem stance. Abnormal findings were more frequent in female athletes for vestibular ocular reflex and visual motion sensitivity. The frequency of abnormal findings increased with age for vestibulo-ocular reflex, visual motion sensitivity, the neck examination, convergence testing, and eyes-open single-leg stance, whereas abnormalities decreased in frequency with age for eyes-open tandem stance and tandem gait. The frequency of abnormal findings generally decreased with time over the first 4 weeks following injury. Discussion: A comprehensive physical examination is pivotal for evaluation of athletes with concussion. These findings highlight high-yield components of the concussion examination and support use of these examination components as injury markers. Future work should investigate associations between physical examination findings and postconcussion symptoms and recovery outcomes. Classification of Evidence: This retrospective cohort study provides Class IV evidence that neurologic examination with specifically designed clinical tests are helpful for diagnosis of traumatic brain injury in young athletes at age 6-24.

The Evaluation and Management of Concussion to Optimize Safe Recovery.

Concussion is a mild traumatic brain injury causing temporary neurologic dysfunction. Symptoms following concussion are variable and generally are expected to resolve within about 1 month, but some patients experience persistent and prolonged symptoms. An early return to safe, symptom-limited activity is now favored, using targeted rehabilitation and treatments. Accommodations may be needed to facilitate return-to-school and work following concussion. Athletes should not be cleared for a full return to sport until they have recovered from a concussion and completed a return-to-play progression, in addition to returning to work/school fully.

Burnout assessment among pharmacist-academic detailers at the US Veterans Health Administration.

BACKGROUND: Burnout among clinical pharmacist practitioners has been well established, but not among those who perform academic detailing. OBJECTIVES: To measure burnout among clinical pharmacist practitioners who perform academic detailing (pharmacist-academic detailers) at the United States Veterans Health Administration and compare the findings using 2 validated burnout instruments for healthcare professionals. METHODS: A cross-sectional study design was performed to measure burnout in VHA pharmacist-academic detailers across all VA regions between April 2023 and May 2023. Burnout was measured using the Oldenburg Burnout Inventory (OLBI) and a validated single-item burnout measure (SIMB). OLBI has 2 domains (exhaustion and disengagement) and categorizes burnout into Low, Moderate, and High based on scores above or below 1 standard deviation (SD) of the mean. The validated SIMB categorized burnout as having a score of 3 or greater (range: 1-5). Interrater reliability testing between the OLBI and the SIMB at detecting burnout among pharmacist-academic detailers was performed using the kappa test. Correlation between the 2 burnout instruments was assessed using the Spearman rho test. RESULTS: A total of 50 pharmacist-academic detailers completed the burnout survey. A large proportion of respondents had Moderate levels of burnout for the total (72%) burnout score, disengagement (64%) domain, and exhaustion (74%) domain. In total, 86% of pharmacist-academic detailers reported having Moderate to High levels of burnout on the total OLBI score. On the SIMB, a total of 14 (28%) pharmacist-academic detailers reported having one or more symptoms of burnout. Interrater reliability was considered poor/slight agreement between the OLBI and SIMB. Correlation between the 2 burnout instruments was considered moderately correlated (rho = 0.67, P < 0.001). CONCLUSION: This study provides an empirical analysis of burnout among pharmacist-academic detailers; however, the ability to detect burnout among pharmacist-academic detailers may be impacted by the selection of burnout instrument used.

Morphology of the early larval stages of Lysmata ankeri Rhyne & Lin, 2006 and Lysmata bahia Rhyne & Lin, 2006 (Caridea: Lysmatidae) and a review of the larval morphology of the early Lysmata stages.

The early larval stages of the shrimps Lysmata ankeri and L. bahia were described, illustrated, and compared among other Lysmata species, providing important information on post-embryonic development and insights into its evolutionary history. Ovigerous specimens of L. ankeri and L. bahia were sampled from southeastern and northeastern Brazilian coast, respectively. For L. ankeri and L. bahia, five and three larval stages were obtained, respectively. Unique features were observed for L. ankeri and L. bahia larvae, and some characteristics may differ only for L. ankeri and L. bahia, which were not observed in the other species analyzed, such as: presence of a pair of simple setae on the third pleonal somite in zoea I and number of setae on the uropod exopod greater than 11. Moreover, several other features are similar between species from the diferent clades of the Lysmata-Exhippolysmata complex, making it possible to identify the early stages of Lysmata larvae. However, future studies will be essential to confirm or not the existence of some phylogenetic patterns and their relevance and other larval characters for better understanding the evolutionary history of this group.

Improving door-to-reperfusion time in acute ischemic stroke during the COVID-19 pandemic: experience from a public comprehensive stroke center in Brazil.

Background: The global COVID-19 pandemic has had a devastating effect on global health, resulting in a strain on healthcare services worldwide. The faster a patient with acute ischemic stroke (AIS) receives reperfusion treatment, the greater the odds of a good functional outcome. To maintain the time-dependent processes in acute stroke care, strategies to reorganize infrastructure and optimize human and medical resources were needed. Methods: Data from AIS patients who received thrombolytic therapy were prospectively assessed in the emergency department (ED) of Hospital de Clínicas de Porto Alegre from 2019 to 2021. Treatment times for each stage were measured, and the reasons for a delay in receiving thrombolytic therapy were evaluated. Results: A total of 256 patients received thrombolytic therapy during this period. Patients who arrived by the emergency medical service (EMS) had a lower median door-to-needle time (DNT). In the multivariable analysis, the independent predictors of DNT >60 min were previous atrial fibrillation (OR 7) and receiving thrombolysis in the ED (OR 9). The majority of patients had more than one reason for treatment delay. The main reasons were as follows: delay in starting the CT scan, delay in the decision-making process after the CT scan, and delay in reducing blood pressure. Several actions were implemented during the study period. The most important factor that contributed to a decrease in DNT was starting the bolus and continuous infusion of tPA on the CT scan table (decreased the median DNT from 74 to 52, DNT ≤ 60 min in 67% of patients treated at radiology service vs. 24% of patients treated in the ED). The DNT decreased from 78 min to 66 min in 2020 and 57 min in 2021 (p = 0.01). Conclusion: Acute stroke care continued to be a priority despite the COVID-19 pandemic. The implementation of a thrombolytic bolus and the start of continuous infusion on the CT scan table was the main factor that contributed to the reduction of DNT. Continuous monitoring of service times is essential for improving the quality of the stroke center and achieving better functional outcomes for patients.

Differences in concussion knowledge between parents and their children in a multidisciplinary concussion clinic sample.

PURPOSE: This study assessed concussion knowledge in concussed youth and parents treated at a multi-disciplinary concussion center. METHODS: Youth (n = 50) and parents (n = 36) were approached at the beginning of a clinical visit. Participants completed a 22-item, previously published concussion knowledge survey before the visit. RESULTS: Responses were compared with previously collected, published data from adolescents in a high school setting (n = 500). The patient group was divided into those with one (n = 23) vs. two or more concussions (n = 27). Chi-square analyses compared total correct responses between youth, parents, and the high school sample. T-tests assessed differences in knowledge based on prior concussions, age, and gender. All groups showed high accuracy for return-to-play guidelines (>90%) and similar knowledge of concussion-related symptoms (72.3% vs. 68.6%). Significant knowledge gaps about diagnosis, neurological consequences, and long-term risks were present across groups (19% to 68% accuracy). The patient group more often misattributed neck symptoms to concussion (X2  < 0.005). Prior concussion and gender were not significant predictors of concussion knowledge (p > 0.5). CONCLUSION: Community and clinically-based educational techniques may not be effectively communicating knowledge about concussion diagnosis, symptoms, long-term risks, and neurological implications of concussion. Educational tools need to be tailored to specific settings and populations.

How can structure and nectar composition explain the secretory process in super productive nuptial nectaries of Mabea fistulifera Mart. (Euphorbiaceae)?

Mabea fistulifera, a species pollinated mainly by diurnal and nocturnal vertebrates, presents pendulous inflorescences with approximately 70 pairs of nuptial nectaries (NNs). These NNs exude voluminous nectar drops that defy gravity, remaining exposed at the inflorescence for more than a day. We aimed to investigate the NN secretory process and the unique nectar presentation of M. fistulifera. NNs and their exudate were collected at different secretory stages and submitted to structural studies and chemical analysis. The epidermis is devoid of stomata and constitutes the main site of synthesis for non-sugar metabolites found on nectar and nectar-coating film. Nectary parenchyma presents few small starch grains, and vascular strands are distributed until the nectary parenchyma cells close to the epidermis. Vascular tissues at the nectary parenchyma seem to provide sugar and water for the nectar. A film composed of lipids, alkaloids, and proteins covers the nectar drops. The film guarantees the nectar offering for several hours, as it minimizes water loss and prevents falls by gravitational action. The release of large nectar drops is intrinsically linked to the NN anatomical traits and the exudate composition. Low sugar concentration and predominance of hexoses in M. fistulifera nectar are essential for maintaining nectar exudation for many hours, which results in the visitation of a broad spectrum of pollinators.

Small RNA Differential Expression Analysis Reveals miRNAs Involved in Dormancy Progression in Sweet Cherry Floral Buds.

In sweet cherry (Prunus avium), as in other temperate woody perennials, bud dormancy allows for survival in adverse environmental conditions during winter. During this process, environmental signals such as short days and/or low temperatures trigger internal signals that enable buds to become tolerant to the cold. The process involves tracking chilling units up to chilling the requirement fulfillment to resume growth, a transition involving transcriptional regulation, metabolic signaling, and epigenetic-related regulatory events. Massive sequencing of small RNAs was performed to identify miRNAs involved in sweet cherry dormancy by comparing their expression in field (regular seasonal) and controlled non-stop (continuous) chilling conditions. miRNAs highlighted by sequencing were validated using specific stem-loop PCR quantification, confirming expression patterns for known miRNAs such as miR156e, miR166c, miR172d, miR391, miR482c, and miR535b, as well as for newly proposed miRNAs. In silico prediction of the target genes was used to construct miRNA/target gene nodes. In particular, the involvement of the sweet cherry version for the miR156/SQUAMOSA PROMOTER-BINDING-LIKE PROTEIN genes whose expression was opposite in the two conditions suggests their involvement on dormancy regulation in sweet cherry. miRNA levels indicate that the regulation of stress-related genes and hormone synthesis modulates the expression of calcium metabolism and cell development-associated genes. Understanding the regulatory networks involved in sweet cherry dormancy, particularly in the context of miRNA involvement, represents the first step in the development of new agricultural strategies that may help overcome the increasing challenges presented by global climate change.

Disparities in Stroke Patient-Reported Outcomes Measurement Between Healthcare Systems in Brazil.

Introduction: Acute stroke interventions, such as stroke units and reperfusion therapy, have the potential to improve outcomes. However, there are many disparities in patient characteristics and access to the best stroke care. Thus, we aim to compare patient-reported outcome measures (PROMs) after stroke in two stroke centers representing the public and private healthcare systems in Brazil. Methods: PROMs through the International Consortium for Health Outcomes Measures (ICHOM) were assessed at 90 days after the stroke to compare two Brazilian hospitals in southern Brazil: a public university and a private stroke center, both with stroke protocols and stroke units. Results: When compared with the private setting (n = 165), patients from the public hospital (n = 175) were younger, had poorer control of risk factors, had more frequent previous strokes, and arrived with more severe strokes. Both hospitals had a similar percentage of IV thrombolysis treatment. Only 5 patients received mechanical thrombectomy (MT), all in the private hospital. Public hospital patients presented significantly worse outcomes at 3 months, including worse quality of life and functional dependence (60 vs. 48%, p = 0.03). Poor outcome, as measured by the mRS score, was significantly associated with older age, higher NIHSS score, and the presence of heart failure. However, the public practice was a strong predictor of any self-reported disability. Conclusion: Patients assisted at a good quality public stroke center with the same protocol used in the private hospital presented worse disability as measured by mRS and patient-reported outcome measures, with greater inability to communicate, dress, toilet, feed, and walk.

Comparison of virtual to in-person academic detailing on naloxone prescribing rates at three U.S. Veterans Health Administration regional networks.

INTRODUCTION: Academic detailing, an educational outreach that promotes evidence-based practices to improve the quality of care for patients, has primarily been delivered using one-on-one in-person interactions. In 2018, the U.S. Department of Veterans Affairs (VA) Pharmacy Benefits Management implemented a pilot virtual academic detailing program to increase naloxone prescribing among veterans at risk for opioid overdose or death. The aim of this evaluation was to compare virtual and in-person academic detailing on naloxone prescribing rates at VA. METHODS: A retrospective quasi-experimental pretest-posttest non-equivalent groups design was used to compare virtual academic detailing and in-person academic detailing on naloxone prescribing rates 12 months before and after providers received a naloxone-specific encounter at three VA regional networks between January 1, 2018 to May 31, 2020. Subgroup analysis was performed on rural providers. Generalized estimating equation models were constructed to compare the difference in naloxone prescribing rates before and after receiving virtual or in-person academic detailing controlling for provider-level characteristics. RESULTS: Providers who received virtual (N = 67) or in-person (N = 186) academic detailing had significant increases in naloxone prescribing, but the differences in the naloxone rates between the groups were not statistically significant (difference in changes in naloxone rates=+0.63; 95% CI: -2.23, 3.48). Similar findings were reported for rural providers. DISCUSSION: Providers who received naloxone-related in-person or virtual academic detailing had increased naloxone prescribing rates; however, there were no differences between the two types of modalities. Virtual academic detailing is a viable alternative for delivering academic detailing and allows academic detailers to expand their reach to rural providers.

COVID-19 vaccine hesitancy and associated factors according to sex: A population-based survey in Salvador, Brazil.

Vaccination is a major strategy to prevent the coronavirus disease 2019 (COVID-19). However, information about factors associated with men and women intention to be vaccinated are scarce. To determine COVID-19 vaccine acceptance and identify factors associated vaccine hesitancy according to sex, we performed a cross-sectional population-based random survey in Salvador, Brazil between Nov/2020-Jan/2021. Participants were interviewed to obtain data on intention to receive and pay for a COVID-19 vaccine, as well as on demographics, comorbidities, influenza vaccination history, previous diagnosis of COVID-19, and exposures and perception of COVID-19 risk. Among 2,521 participants, 2,053 (81.4%) reported willingness to use a COVID-19 vaccine and 468 (18.6%) hesitated to take it. Among those intending to get vaccinated, 1,400 (68.2%) would pay for the vaccine if necessary. Sex-stratified multivariable analysis found that men who were working and who had comorbidities were less likely to hesitate about using the vaccine. Among women, higher educational level and high perception of COVID-19 risk were associated with less vaccine hesitancy. In both groups, reporting influenza vaccination in 2020 reduced the chance of COVID-19 vaccine hesitancy. COVID-19 vaccine campaigns targeting to reduce vaccine hesitancy are urgently needed. These campaigns should consider gender differences in order to be successful.

Implementation of a pharmacy-led virtual academic detailing program at the US Veterans Health Administration.

PURPOSE: To provide a summary of the implementation of a virtual academic detailing pilot program at the US Department of Veterans Affairs (VA). SUMMARY: In September 2018, VA Pharmacy Benefits Management implemented a virtual academic detailing ("e-Detailing") pilot program across 3 regional networks. Academic detailing involves multifaceted collaborative outreach delivered by trained healthcare clinicians to other clinicians using targeted educational interventions that improve clinical decision-making. Across VA, academic detailing programs are primarily staffed by specially trained clinical pharmacist specialists. Implementation began with an in-person meeting to train academic detailers on using the virtual academic detailing platform (VA Video Connect) and virtual soft skills, which was followed by regular facilitation meetings to address issues and share experiences. During e-Detailing program implementation, coronavirus disease 2019 (COVID-19) emerged, prompting the US Department of Health and Human Services to declare a public health emergency. VA followed with restrictions on nonessential travel for all employees, thus hampering in-person academic detailing activities. Fortunately, e-Detailing provided an alternative channel for academic detailers across VA to continue delivering critical outreach to providers during the pandemic. Qualitative assessment of academic detailers' and providers' perceptions on e-Detailing highlighted the need for local leadership support for e-Detailing and telehealth, the efficiency of virtual compared to in-person visits, and potential time savings resulting from avoidance of long commutes. CONCLUSION: The timing of e-Detailing implementation during the COVID-19 pandemic illustrates the need and potential for a virtual platform to deliver timely provider outreach.

Factor Structure for the Sport Concussion Assessment Tool Symptom Scale in Adolescents After Concussion.

OBJECTIVE: To examine the factor structure of the Sport Concussion Assessment Tool-5 (SCAT5) symptom scale in adolescents on their initial presentation to a concussion clinic within the typical recovery period after concussion (ie, <30 days). We hypothesize that the SCAT5 symptoms represent various clinically meaningful groups. A secondary purpose was to examine the effects of sex on the factor structure of the SCAT5 symptom scale. STUDY DESIGN: Retrospective cross-sectional analysis. SETTING: Tertiary, institutional. PATIENTS: Nine hundred eighty-one adolescents (45% women) aged between 13 and 18 years. INDEPENDENT VARIABLES: Adolescents completed the SCAT5 symptom scale. MAIN OUTCOME MEASURES: The factor structure of SCAT5 examined using a principal axis factor analysis. RESULTS: A 5-factor structure model explained 61% of the variance in symptoms. These 5 factors are identified as Energy (17%), Mental Health (13%), Migrainous (13%), Cognitive (9%), and Vestibulo-Ocular (9%). A similar 5-factor model emerged for each sex, and the proportion of variance in symptoms explained by the 5-factor model was comparable between the sexes. CONCLUSIONS: The findings of this report indicate that the SCAT5 symptoms aggregated into 5 delineated factors, and these factors were largely consistent across the sexes. The delineation of symptoms into 5 factors provides preliminary validation for the presence of different concussion phenotypes. Confirmatory factor analysis is warranted to examine the applicability and clinical utility of the use of the 5-factor structure in a clinical setting.

Morphology of the early larval stages of Lysmata lipkei Okuno amp; Fiedler, 2010 (Caridea: Lysmatidae): an invasive shrimp in the Western Atlantic.

Considering the importance of establishing different approaches to the early detection of invasive species, the present study aimed to describe and illustrate the morphology of the early larval stages of the shrimp Lysmata lipkei, an invasive species in the Western Atlantic. Additionally, we did a morphological comparison and a review of the other Lysmata species from the Western Atlantic Ocean with a known larvae description. The larvae used in this study were obtained by the maintenance, under laboratory conditions, of ovigerous hermaphrodites of L. lipkei, collected in the wild. Then, larvae were dissected under a stereo microscope and illustrated using a microscope equipped with a camera lucida. The first three larval stages (zoeae) of L. lipkei were illustrated, described, and compared to other species of Lysmata previously described of the Western Atlantic. Some features of the larval morphology of L. lipkei are very similar when compared to other Lysmata species with previous larval descriptions, such as a rostrum long and simple, the eyes stalked with a long peduncle from the second zoeae, one pterygostomian spine and several denticles along the anterior ventral margin of the carapace, similarities in the segmentation of the maxillipeds, and the presence of dorsolateral spines on the posterior margin of the 5th pleomere, among other features. Also, unique features were observed for L. lipkei, such as differences in the setation of some structures, including the antennule, antenna, maxillule, and maxillipeds. Using the morphological descriptions, we expect to identify species from the plankton, especially invaders, that might be present in the Western Atlantic, as well as assist in several areas in which the larval morphology is relevant.

Do male and female adolescents report symptoms differently after concussion?

We investigated sex-based differences in the presence and severity of aggregated symptom indicators as well as individual concussion symptoms.Materials and Methods: A cross-sectional examination of sex differences in symptoms reported by adolescents upon initial concussion evaluation at a concussion clinic. Nine hundred and eighty-six adolescents completed the Sport Concussion Assessment Tool (SCAT5) symptom checklist. Chi-square and Mann-Whitney U tests were used for differences in the presence and severity of symptoms, respectively. Sex differences in global indices of symptom distress were compared.Results: Females endorsed more symptoms (Female: Median (M)=15, Interquartile range (IQR):9-18 vs. Male: M=11, IQR: 6-15, p<0.001) and a greater total symptom score (Female: M=37, IQR:16-45 vs. Male: M=20, IQR:8-39). After False Discovery Rate (FDR) adjustment, females endorsed the presence of 21 of 22 individual symptoms more frequently than males (p≤ 0.039), with greater symptom severity for 20 of 22 individual symptoms (p≤0.036). Moderate ESs were observed for sex-based differences in the total symptom score and the global severity index. Small ESs was observed for differences in most individual symptoms.Conclusions: The greater frequency and severity of concussion symptoms reported by female adolescents highlights the importance of considering sex as a modifier for the management of concussion.
