Emergency Approach to Acute Seizures in Dogs and Cats.

Seizures are a common presentation seen in small animal practices. Seizures require prompt management including initial interventions for triage, stabilization, and treatment with first-line anticonvulsant (AC) drugs like benzodiazepines. Concurrently, ruling out metabolic or extracranial causes with point-of-care diagnostics can help guide further diagnostics and treatments. Analysis of the history and a physical exam are also necessary to rule out common "look-alikes" that require specific diagnostic workup and treatments. Typically, causes of seizures can be grouped into intracranial and extracranial causes, with the latter being easier to diagnose with commonly available tests. This review presents a systematic approach to the diagnosis and treatment of single seizures, cluster seizures, and status epilepticus in dogs and cats.

The Effect of Intranasal Plus Transcranial Photobiomodulation on Neuromuscular Control in Individuals with Repetitive Head Acceleration Events.

Objective: This proof-of-concept study was to investigate the relationship between photobiomodulation (PBM) and neuromuscular control. Background: The effects of concussion and repetitive head acceleration events (RHAEs) are associated with decreased motor control and balance. Simultaneous intranasal and transcranial PBM (itPBM) is emerging as a possible treatment for cognitive and psychological sequelae of brain injury with evidence of remote effects on other body systems. Methods: In total, 43 (39 male) participants, age 18-69 years (mean, 49.5; SD, 14.45), with a self-reported history of concussive and/or RHAE and complaints of their related effects (e.g., mood dysregulation, impaired cognition, and poor sleep quality), completed baseline and posttreatment motor assessments including clinical reaction time, grip strength, grooved pegboard, and the Mini Balance Evaluation Systems Test (MiniBEST). In the 8-week interim, participants self-administered itPBM treatments by wearing a headset comprising four near-infrared light-emitting diodes (LED) and a near-infrared LED nasal clip. Results: Posttreatment group averages in reaction time, MiniBEST reactive control subscores, and bilateral grip strength significantly improved with effect sizes of g = 0.75, g = 0.63, g = 0.22 (dominant hand), and g = 0.34 (nondominant hand), respectively. Conclusion: This study provides a framework for more robust studies and suggests that itPBM may serve as a noninvasive solution for improved neuromuscular health.

Health-care workforce implications of the Dobbs v Jackson Women's Health Organization decision.

The Dobbs v Jackson Women's Health Organization Supreme Court decision, which revoked the constitutional right to abortion in the USA, has impacted the national medical workforce. Impacts vary across states, but providers in states with restrictive abortion laws now must contend with evolving legal and ethical challenges that have the potential to affect workforce safety, mental health, education, and training opportunities, in addition to having serious impacts on patient health and far-reaching societal consequences. Moreover, Dobbs has consequences on almost every facet of the medical workforce, including on physicians, nurses, pharmacists, and others who work within the health-care system. Comprehensive research is urgently needed to understand the wide-ranging implications of Dobbs on the medical workforce, including legal, ethical, clinical, and psychological dimensions, to inform evidence-based policies and standards of care in abortion-restrictive settings. Lessons from the USA might also have global relevance for countries facing similar restrictions on reproductive care.

Societal implications of the Dobbs v Jackson Women's Health Organization decision.

On June 24, 2022, the US Supreme Court's decision in Dobbs v Jackson Women's Health Organization marked the removal of the constitutional right to abortion in the USA, introducing a complex ethical and legal landscape for patients and providers. This shift has had immediate health and equity repercussions, but it is also crucial to examine the broader impacts on states, health-care systems, and society as a whole. Restrictions on abortion access extend beyond immediate reproductive care concerns, necessitating a comprehensive understanding of the ruling's consequences across micro and macro levels. To mitigate potential harm, it is imperative to establish a research agenda that informs policy making and ensures effective long-term monitoring and reporting, addressing both immediate and future impacts.

ENIGMA's simple seven: Recommendations to enhance the reproducibility of resting-state fMRI in traumatic brain injury.

Resting state functional magnetic resonance imaging (rsfMRI) provides researchers and clinicians with a powerful tool to examine functional connectivity across large-scale brain networks, with ever-increasing applications to the study of neurological disorders, such as traumatic brain injury (TBI). While rsfMRI holds unparalleled promise in systems neurosciences, its acquisition and analytical methodology across research groups is variable, resulting in a literature that is challenging to integrate and interpret. The focus of this narrative review is to address the primary methodological issues including investigator decision points in the application of rsfMRI to study the consequences of TBI. As part of the ENIGMA Brain Injury working group, we have collaborated to identify a minimum set of recommendations that are designed to produce results that are reliable, harmonizable, and reproducible for the TBI imaging research community. Part one of this review provides the results of a literature search of current rsfMRI studies of TBI, highlighting key design considerations and data processing pipelines. Part two outlines seven data acquisition, processing, and analysis recommendations with the goal of maximizing study reliability and between-site comparability, while preserving investigator autonomy. Part three summarizes new directions and opportunities for future rsfMRI studies in TBI patients. The goal is to galvanize the TBI community to gain consensus for a set of rigorous and reproducible methods, and to increase analytical transparency and data sharing to address the reproducibility crisis in the field.

Science and Sex-A Bold Agenda for Women's Health.

This Viewpoint examines why investigators should address women's health in all biomedical and health-related research.

Clinical Assessment of Primary Hemostasis: A Review.

Primary hemostatic disorders such as thrombocytopenia and thrombocytopathia are commonly encountered in small animal practice. The key stages of primary hemostasis include platelet adhesion, activation, and aggregation. Understanding the interaction between tissues, platelets, and signaling molecules not only helps clinicians comprehend clot formation but also better recognize thrombocytopathias. Although congenital thrombocytopathia is rare, commercially available platelet function tests allow veterinarians to narrow differentials in many clinical settings. Thrombocytopenia can be easily diagnosed in any clinical setting. In this paper, we review the current understanding of primary hemostasis in veterinary medicine, including the clinical presentation and available diagnostics to identify platelet abnormalities.

Comparison of 4 point-of-care techniques to detect correct positioning of nasogastric tubes in dogs (2020-2021).

OBJECTIVE: To compare 4 point-of-care (POC) techniques to assess nasogastric (NG) tube placement versus radiographs as a reference standard. POC methods included air inflation with auscultation, fluid aspiration with pH measurement, ultrasonography, and capnography. DESIGN: Prospective observational study in hospitalized dogs between 2020 and 2021. SETTING: University teaching hospital. ANIMALS: Fifty-one dogs requiring NG tube placement as part of their normal care. INTERVENTIONS: After standard blind NG tube placement, each POC method was performed following standardized instructions. All POC methods were scored as to whether the investigator believed the tube to be in the gastrointestinal tract (as indicated by positive auscultation of borborygmus during insufflation, positive fluid aspiration with pH ≤5, presence of hyperechoic shadow in the esophagus, or absence of capnographic waveform). Subsequently, radiographs were taken to determine NG tube position as a gold standard. The sensitivity, specificity, and accuracy of each test as compared to 2-view thoracic radiographs were determined. MEASUREMENTS AND MAIN RESULTS: Sensitivity, specificity, and accuracy for each POC technique were as follows: air auscultation (84.4%, 50.5%, and 80.4%, respectively), neck ultrasound (95.6%, 83.3%, and 94.1%, respectively), capnography (91.1%, 33.3%, and 84.3%, respectively), and fluid aspiration with pH measurement (22.2%, 100%, and 31.4%, respectively). CONCLUSIONS: Among the 4 techniques evaluated, neck ultrasound had the best overall performance for assessing NG tube placement. Fluid aspiration with pH measurement might also have potential due to perfect specificity, but its clinical utility may be limited by low sensitivity and accuracy. Nonetheless, 2-view thoracic radiography should still be considered the standard method for confirmation of NG tube placement as none of the 4 POC techniques investigated showed both high sensitivity and perfect specificity.

Interstitial glucose monitoring has acceptable clinical accuracy in juvenile dogs.

OBJECTIVE: To compare the performance of an interstitial glucose monitor (IGM) versus a portable blood glucose monitor (PBGM) in sick juvenile dogs in a veterinary ICU. ANIMALS: 16 client-owned dogs admitted to the university teaching hospital under 1 year of age with systemic illness. PROCEDURES: Paired interstitial and blood glucose samples were collected. A third glucose measurement with a reference method was obtained when IGM and PBGM values were clinically disparate. Analytical accuracy was measured by Pearson correlation and agreement statistics, including mean absolute relative difference (MARD), bias, and 95% limits of agreement. The Parkes consensus error grid analysis was performed to assess clinical accuracy. RESULTS: 159 paired glucose measurements were available for analysis. Comparison of IGM readings to PBGM measurements resulted in an MARD of 15.4% and bias of -2.6%, with the 95% limits of agreement ranging from -42.5% to 37.4%. Positive correlation between IGM and PBGM (Pearson r = 0.65) was found. On consensus error grid analysis, 100% of the pairs fell into clinically acceptable zones (74.2% in zone A, and 25.8% in zone B). When disparate IGM and PBGM readings were compared to a laboratory reference standard (n = 13), both methods resulted in high MARD and wide limits of agreement. CLINICAL RELEVANCE: The IGM provides clinically acceptable glucose measurements compared to PBGM to monitor glucose levels in juvenile dogs in a clinical setting. Further clinical studies with a larger sample size, particularly in the hypoglycemic range, are needed to assess IGM performance in the lower glucose range.

Feasibility of using the Leap Motion Controller to administer conventional motor tests: a proof-of-concept study.

Although upper-limb movement impairments are common, the primary tools for assessing and tracking impairments in clinical settings are limited. Markerless motion capture (MMC) technology has the potential to provide a large amount of quantitative, objective movement data in routine clinical use. Many past studies have focused on whether MMC are sufficiently accurate. However, another necessary step is to create meaningful clinical tests that can be administered via MMC in a robust manner. Four conventional upper-limb motor tests common in clinical assessments (visually guided movement, finger tapping, postural tremor, and reaction time) were modified so they can be administered via a particular MMC sensor, the Leap Motion Controller (LMC). In this proof-of-concept study, we administered these modified tests to 100 healthy subjects and present here the successes and challenges we encountered. Subjects generally found the LMC and the graphical user interfaces of the tests easy to use. The LMC recorded movement with sufficiently high sampling rate (>106 samples/s), and the rate of LMC malfunctions (mainly jumps in time or space) was low, so only 1.9% of data was discarded. However, administration of the tests also revealed some significant weaknesses. The visually guided movement test was easily implemented with the LMC; the modified reaction time test worked reasonably well with the LMC but is likely more easily implemented with other existing technologies; and the modified tremor and finger tapping tests did not work well because of the limited bandwidth of the LMC. Our findings highlight the need to develop and evaluate motor tests specifically suited for MMC. The real strength of MMC may not be in replicating conventional tests but rather in administering new tests or testing conditions not possible with conventional clinical tests or other technologies.

Differences in personal care product use by race/ethnicity among women in California: implications for chemical exposures.

BACKGROUND: Personal care products may contain many chemicals, some of which are suspected endocrine disrupters. This is an important source of chemical exposure for women, but little is known about how chemical exposure differs among different races/ethnicities. OBJECTIVE: This study examines differences in personal care product use among Black, Latina, Vietnamese, Mixed Race, and White women in California. METHODS: We used a community-based participatory process to create and administer a personal care product usage survey to 321 Black, Latina, Vietnamese, Mixed Race, and White women. We used multivariate regression models with pairwise comparisons to examine the frequency of product use by race/ethnicity. RESULTS: We found distinct trends of personal care product use by race/ethnicity: Latina women typically used makeup most frequently; Black women used certain hair products or styles most frequently; and Vietnamese women were most likely to use facial cleansing products compared to other races/ethnicities. Latina and Vietnamese women were less likely to try to avoid certain ingredients in their products. SIGNIFICANCE: These findings can help estimate disparities in chemical exposure from personal care product use and complement future research on health inequities due to chemical exposures in the larger environmental and social context.

Researcher degrees of freedom in statistical software contribute to unreliable results: A comparison of nonparametric analyses conducted in SPSS, SAS, Stata, and R.

Researcher degrees of freedom can affect the results of hypothesis tests and consequently, the conclusions drawn from the data. Previous research has documented variability in accuracy, speed, and documentation of output across various statistical software packages. In the current investigation, we conducted Pearson's chi-square test of independence, Spearman's rank-ordered correlation, Kruskal-Wallis one-way analysis of variance, Wilcoxon Mann-Whitney U rank-sum tests, and Wilcoxon signed-rank tests, along with estimates of skewness and kurtosis, on large, medium, and small samples of real and simulated data in SPSS, SAS, Stata, and R and compared the results with those obtained through hand calculation using the raw computational formulas. Multiple inconsistencies were found in the results produced between statistical packages due to algorithmic variation, computational error, and statistical output. The most notable inconsistencies were due to algorithmic variations in the computation of Pearson's chi-square test conducted on 2 × 2 tables, where differences in p-values reported by different software packages ranged from .005 to .162, largely as a function of sample size. We discuss how such inconsistencies may influence the conclusions drawn from the results of statistical analyses depending on the statistical software used, and we urge researchers to analyze their data across multiple packages to check for inconsistencies and report details regarding the statistical procedure used for data analysis.

Chemicals of concern in personal care products used by women of color in three communities of California.

BACKGROUND: Personal care products (PCPs) may contain chemicals associated with adverse health effects. Prior studies found differences in product use by race/ethnicity and suggest some women are disproportionately exposed to chemicals of concern (CoCs). OBJECTIVE: We quantified chemicals linked to cancer, reproductive or developmental harm, or endocrine disruption in PCPs used by women of color. METHODS: We documented PCPs in stores frequented by Black, Latina, and Vietnamese women in their communities in California and CoCs on ingredient labels of 546 unique hair, skin, makeup, nail, deodorant/perfume, and intimate care products. Community partners chose 31 products for a combined targeted and suspect screen (National Institute of Standards and Technology mass spectral library search) two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC-TOFMS) analysis to detect chemicals not on ingredient labels. RESULTS: We found that 65% of labels included CoCs, and 74% of labels had undisclosed ingredients listed as "fragrance." The most prevalent chemicals were parabens, cyclosiloxanes, and formaldehyde releasers. GCxGC-TOFMS found additional CoCs, including fragrances, solvents, preservatives, ultraviolet filters, and contaminants. SIGNIFICANCE: These findings contribute to awareness of potentially hazardous chemicals in PCPs, can help estimate disparities in chemical exposure, and complement research on health inequities due to chemical exposures from various contributors. IMPACT STATEMENT: This study is one of the first detailed assessments of chemicals of concern found in various types of PCPs used by several racial/ethnic groups. We found that over half of the 546 products selected by community partners as marketed to and/or used by them contained ingredients linked to cancer, reproductive or developmental harm, or endocrine disruption. Laboratory analysis identified additional chemicals in a subset of products, including unlabeled fragrance chemicals and contaminants. Elucidating exposures to chemicals in PCPs is important for risk assessment and health inequity research.

Comparison of a commercial immunochromatographic strip crossmatch kit and standard laboratory crossmatch methods for blood transfusion compatibility in dogs.

OBJECTIVE: To evaluate agreement between 2 standard laboratory (SL) methods and an immunochromatographic strip (ICS) method to crossmatch dogs receiving RBC transfusions. A second objective was to evaluate uninterpretable SL crossmatch results as compared to ICS in the presence of autoagglutination. DESIGN: Prospective observational study (September 2018 to October 2019). SETTING: University teaching hospital. ANIMALS: Forty anemic dogs receiving RBC transfusions. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: All dogs received DEA 1-negative packed RBCs. Three crossmatch methods were evaluated against the same unit transfused to each dog: SL method performed at institutional laboratory (SL-I), SL method sent to a commercial laboratory (SL-C), and a commercially available point-of-care ICS method. Major and minor crossmatches were incompatible for 2.5%/7.5% of ICS tests, 82.5%/52.5% of SL-I tests, and 52.5%/27.5% of SL-C tests. Agreement between ICS and SL-C major (κ = 0.05) and minor (κ = 0.02) crossmatches and between ICS and SL-I major (κ = 0.009) and minor (κ = 0.03) crossmatches was slight. Agreement between SL-C and SL-I major (κ = -0.06) and minor (κ = -0.12) crossmatches was poor. Results of major and minor crossmatches were uninterpretable due to autoagglutination in 38%/38% for SL-I and 29%/18% for SL-C crossmatches. ICS method was interpretable for 93% (major) and 98% (minor) crossmatches. After exclusion of uninterpretable SL pairings, agreement still remained poor to slight between all tests. Only 1 of 40 dogs (2.5%; 95% confidence interval: <1.0%-13.2%) had an immediate immunological transfusion reaction. CONCLUSIONS: Lack of agreement between all methodologies was noted. The high level of incompatibility predicted by SL methods despite lack of clinically relevant reactions suggests a high false incompatibility rate as compared to the ICS test. ICS testing was also able to give results more frequently in the face of autoagglutination. Further work is needed to investigate the ICS method's ability to predict clinically significant transfusion reactions.

Sensory Phenotypes for Balance Dysfunction After Mild Traumatic Brain Injury.

BACKGROUND AND OBJECTIVES: Recent team-based models of care use symptom subtypes to guide treatments for individuals with chronic effects of mild traumatic brain injury (mTBI). However, these subtypes, or phenotypes, may be too broad, particularly for balance (e.g., 'vestibular subtype'). To gain insight into mTBI-related imbalance we 1) explored whether a dominant sensory phenotype (e.g., vestibular impaired) exists in the chronic mTBI population, 2) determined the clinical characteristics, symptomatic clusters, functional measures, and injury mechanisms that associate with sensory phenotypes for balance control in this population, and 3) compared the presentations of sensory phenotypes between individuals with and without previous mTBI. METHODS: A secondary analysis was conducted on the Long-Term Impact of Military-Relevant Brain Injury Consortium - Chronic Effects of Neurotrauma Consortium. Sensory ratios were calculated from the Sensory Organization Test, and individuals were categorized into one of eight possible sensory phenotypes. Demographic, clinical, and injury characteristics were compared across phenotypes. Symptoms, cognition, and physical function were compared across phenotypes, groups, and their interaction. RESULTS: Data from 758 Service Members and Veterans with mTBI and 172 with no lifetime history of mTBI were included. Abnormal visual, vestibular, and proprioception ratios were observed in 29%, 36%, and 38% of people with mTBI, respectively, with 32% exhibiting more than one abnormal sensory ratio. Within the mTBI group, global outcomes (p<0.001), self-reported symptom severity (p<0.027), and nearly all physical and cognitive functioning tests (p<0.027) differed across sensory phenotypes. Individuals with mTBI generally reported worse symptoms than their non-mTBI counterparts within the same phenotype (p=0.026), but participants with mTBI in the Vestibular-Deficient phenotype reported lower symptom burdens than their non-mTBI counterparts [e.g., mean(SD) Dizziness Handicap Inventory = 4.9(8.1) for mTBI vs. 12.8(12.4) for non-mTBI, group*phenotype interaction p<0.001]. Physical and cognitive functioning did not differ between groups after accounting for phenotype. DISCUSSION: Individuals with mTBI exhibit a variety of chronic balance deficits involving heterogeneous sensory integration problems. While imbalance when relying on vestibular information is common, it is inaccurate to label all mTBI-related balance dysfunction under the 'vestibular' umbrella. Future work should consider specific classification of balance deficits, including specific sensory phenotypes for balance control.

Our quest for creating a space that is welcoming to all: A commentary from the American College of Veterinary Emergency and Critical Care Diversity, Equity, and Inclusion Committee.

Diversity, equity, and inclusion (DEI) are crucial elements of successful veterinary emergency and critical care practices across the world. Embracing the elements of DEI creates a work environment that is safe and welcoming for all the members of the team. The American College of Veterinary Emergency and Critical Care DEI committee was formed to enhance and support efforts to increase racial diversity in veterinary emergency and critical care, as well as provide resources that will generate DEI practices across the country. This article provides an overview of the vision of the committee and some of the steps that have been taken to create a welcoming space for all represented in veterinary emergency and critical care.

Conventional versus high-flow oxygen therapy in dogs with lower airway injury.

Dogs with lower airway pathology that present in respiratory distress often receive oxygen therapy as the first line of treatment regardless of the underlying cause. Conventional "low-flow" systems deliver oxygen with a maximum flow rate of 15 L/minute. Traditionally, when an animal's respiratory status does not improve with conventional oxygen therapy and treatments for underlying disease, options might be limited to either intubation and mechanical ventilation or humane euthanasia. High-flow oxygen therapy (HFOT) has been gaining popularity in veterinary medicine as an alternative route of oxygen supplementation for animals that require support beyond conventional therapy. High-flow oxygen therapy can supply a mixture of air and oxygen via a heated and humidified circuit. It is user friendly and can be used in an environment in which mechanical ventilation is unavailable. This review article is written for emergency doctors and general practitioners who lack access to mechanical ventilation. This article briefly reviews pertinent respiratory physiology, traditional oxygen supplementation techniques, the physiology of HFOT, and the limited evidence available in veterinary medicine regarding the use of HFOT, its applications, and limitations. Guidelines for the use of HFOT are suggested and HFOT is compared to conventional therapy.

Les chiens avec une pathologie des voies respiratoires inférieures qui présentent une détresse respiratoire reçoivent souvent une oxygénothérapie en première intention, quelle que soit la cause sous-jacente. Les systèmes conventionnels à « faible débit ¼ fournissent de l'oxygène avec un débit maximum de 15 L/minute. Traditionnellement, lorsque l'état respiratoire d'un animal ne s'améliore pas avec l'oxygénothérapie conventionnelle et les traitements de la maladie sous-jacente, les options peuvent se limiter à l'intubation et à la ventilation mécanique ou à l'euthanasie. L'oxygénothérapie à haut débit (HFOT) gagne en popularité en médecine vétérinaire en tant que voie alternative de supplémentation en oxygène pour les animaux qui nécessitent un soutien au-delà de la thérapie conventionnelle. L'oxygénothérapie à haut débit peut fournir un mélange d'air et d'oxygène via un circuit chauffé et humidifié. Il est convivial et peut être utilisé dans un environnement où la ventilation mécanique n'est pas disponible.Cet article de revue est écrit pour les médecins urgentistes et les médecins généralistes qui n'ont pas accès à la ventilation mécanique. L'article passe brièvement en revue la physiologie respiratoire pertinente, les techniques traditionnelles de supplémentation en oxygène, la physiologie de la HFOT et les preuves limitées disponibles en médecine vétérinaire concernant l'utilisation de la HFOT, ses applications et ses limites. Des lignes directrices pour l'utilisation de la HFOT sont suggérées et la HFOT est comparée au traitement conventionnel.(Traduit par Docteur Serge Messier).

Assessment of the physical compatibility of injectable enrofloxacin with commonly used intravenous fluids and drugs during simulated Y-port administration.

OBJECTIVE: To evaluate physical compatibility of small animal (SAE) and large animal (LAE) injectable formulations of enrofloxacin with select IV fluids and drugs. SAMPLE: 162 admixtures containing SAE or LAE with saline (0.9% NaCl) solution, lactated Ringer solution (LRS), Plasma-Lyte A (PLA), 6% hydroxyethylstarch 130/0.4 (HES), metoclopramide, or ampicillin-sulbactam. PROCEDURES: In the first of 2 simultaneously conducted experiments, admixtures containing enrofloxacin (10 mg/kg) and a volume of IV fluid that would be administered over a 20-minute period when dosed at the maintenance infusion rate (40 mL/kg/d for saline solution, LRS, and PLA and 20 mL/kg/d for HES) were created. In the second experiment, enrofloxacin (10 mg/kg) was admixed with saline solution (40 mL/kg/d) and metoclopramide (2 mg/kg/d) or ampicillin-sulbactam (30 mg/kg). In both experiments, admixture components were infused into a flask over 20 minutes assuming patient weights of 5, 10, and 20 kg. Admixtures were created by use of undiluted SAE and SAE diluted 1:1 with saline solution and undiluted LAE and LAE diluted 1:1 and 1:10 with saline solution. Admixtures were assessed for physical incompatibility at 0, 15, 30, and 60 minutes after completion of mixing. Physical incompatibility was defined as gross precipitation, cloudiness, Tyndall effect, or change in turbidity. RESULTS: Admixtures containing undiluted SAE or LAE were physically incompatible with saline solution, PLA, LRS, and HES. Because saline solution was used to dilute SAE and LAE, all admixtures containing diluted SAE or LAE were also physically incompatible. Physical compatibility of enrofloxacin with metoclopramide or ampicillin-sulbactam could not be assessed because those admixtures also contained saline solution. CONCLUSIONS AND CLINICAL RELEVANCE: Enrofloxacin was physically incompatible with all tested solutions.

Research Conducted in Women Was Deemed More Impactful but Less Publishable than the Same Research Conducted in Men.

Background: Female scientists, who are more likely than their male counterparts to study women and report findings by sex/gender, fare worse in the article peer review process. It is unknown whether the gender of research participants influences the recommendation to publish an article describing the study. Materials and Methods: Reviewers were randomly assigned to evaluate one of three versions of an article abstract describing a clinical study conducted in men, women, or individuals. Reviewers assessed the study's scientific rigor, its level of contribution to medical science, and whether they would recommend publishing the full article. Responses were analyzed with logistic regression controlling for reviewer background variables, including sex and experience level. Results: There was no significant difference in perceived research rigor by abstract condition; contribution to medical science was perceived to be greater for research conducted in women than men (odds ratio = 1.7; p = 0.030). Nevertheless, reviewers were almost twice as likely to recommend publication for research conducted in men than the same research conducted in women (predicted probability 0.606 vs. 0.322; p = 0.000). Conclusions: These results are consistent with abundant data from multiple sources showing a lower societal value placed on women than men. Because female investigators are more likely than male investigators to study women, our findings suggest a previously unrecognized bias that could contribute to gender asymmetries in the publication outcomes of peer review. This pro-male publication bias could be an additional barrier to leadership attainment for women in academic medicine and the advancement of women's health.
