Incident Epilepsy Among US Medicare Beneficiaries, 2019: Differences by Age, Sex, and Race/Ethnicity.

BACKGROUND AND OBJECTIVES: Epilepsy is common among older adults, but previous incident studies have had limited ability to make comparisons across key subgroups. We aimed to provide updated epilepsy incidence estimates among older adults, comparing across age, sex, and race/ethnicity. METHODS: Using a random sample of 4,999,999 US Medicare beneficiaries older than 65 years, we conducted a retrospective cohort study of epilepsy incidence using administrative claims for 2016-2019. Sampled beneficiaries were enrolled in the Fee-for-Service (FFS) program in each of 2016-2018 and had no epilepsy claims in those years. Non-Hispanic Black and Hispanic beneficiaries were oversampled to ensure adequate cases for detailed comparisons. Incidence in 2019 was identified in the Master Beneficiary Summary File as ≥1 inpatient claim or ≥2 outpatient nondrug claims occurring at least 1 day apart (ICD-10 G40.x). Incidence models were estimated by age, sex, race/ethnicity, and combinations thereof, with adjustment for the racial/ethnic oversampling. RESULTS: We identified 20,545 incident epilepsy cases. The overall epilepsy incidence rate (IR) was 393 per 100,000 (99% CI 385-400). Incidence peaked at ages 85-89 (504 [481-529]) and was higher for men (396 [385-407]) than women (376 [366-385]). The sex difference in IRs was constant with age. Incidence was higher for non-Hispanic Black (678 [653-702]) and Hispanic (405 [384-426]), and lower for non-Hispanic Asian/Pacific Islander (272 [239-305]) beneficiaries, compared with non-Hispanic White beneficiaries (354 [299-408]). The age-specific IRs significantly differed by race/ethnicity and sex, but only among non-Hispanic Black beneficiaries-where men had higher rates at younger ages and women at older ages. DISCUSSION: We found higher epilepsy IRs among those enrolled in the Medicare FFS system 2016-2019 than previous studies using Medicare claims data from at least a decade ago. The risk of epilepsy onset is higher for those in their late 80s, men, and non-Hispanic Black and Hispanic older adults. There is also evidence that these age-graded risks operate differently for Black men and Black women. Efforts to provide care and services that improve quality of life for older adults living with epilepsy should consider differences by multiple social characteristics simultaneously: age, sex, and race/ethnicity.

Sexual Expression and Subsequent Marital Quality Among Partnered Older Adults.

A great deal of research has linked aspects of couples' sex lives to the quality of their relationships. Yet most of this work is with younger couples. Although sexual frequency is associated with positive marital quality, less is known regarding how sexual expression-sexual attitudes, desires, and behaviors-influences later positive and negative marital quality, particularly in older couples. Using latent class analysis and dyadic data on 620 heterosexual couples in long-term marriages from Rounds 2 and 3 of the National Social Life, Health, and Aging Project, we examined how couple-level configurations of sexual expression influence later marital quality. Generally, the latent classes with more agreement on sexual expression and higher overall sexual frequency were associated with later higher positive marital quality for both wives and husbands. Sexual expression configurations were associated with wives' negative marital quality, not husbands' negative marital quality. Across classes, wives' better mental health and husbands' functional limitations were associated with later marital quality. It is essential for practitioners to recognize the relevance of sexual expression to marital quality in older couples.

How Does Successful Aging Apply To Black Women?: A Latent Class Analysis.

BACKGROUND AND OBJECTIVES: Although prior research has identified racial/ethnic and gender differences in successful aging (SA), heterogeneity within groups has been little examined. We consequently explore the variety of aging experiences among older Black women. RESEARCH DESIGN AND METHODS: We used the 2010/2012 U.S. Health and Retirement Study, limiting analyses to Black women who completed the Psychosocial Leave-Behind Questionnaire (N = 1,186). We conducted latent class analysis (LCA) using indicators of physical health, psychological well-being, social support/strain, and social engagement. RESULTS: Six SA latent classes were identified and labeled according to their distinctive characteristics: infirm, isolated, taxed, independent, vivacious, and robust. The infirm class had uniformly poor health, while the isolated class was in poor physical health but also lacked social relations. Although both had average physical health and psychological well-being, the taxed class experienced high levels of social support and social strain compared to the high support (and unpartnered) independent class. The vivacious and robust classes exhibited high physical health and psychological well-being, high social support/low social strain, and high social engagement, but vivacious women (23% of respondents) were unpartnered and robust women (16% of respondents) were partnered. The robust class had the highest physical and psychological well-being, and best social relations across all classes. DISCUSSION AND IMPLICATIONS: Using nationally representative data, we reveal significant heterogeneity in Black women's aging experiences. Although many face difficult aging experiences, 39% of older Black women fit the SA framework well. Future work should recognize that Black women's aging experiences are not homogenous.

Administration of the American Board of Anesthesiology's virtual APPLIED Examination: successes, challenges, and lessons learned.

In response to the COVID-19 pandemic, the American Board of Anesthesiology transitioned from in-person to virtual administration of its APPLIED Examination, assessing more than 3000 candidates for certification purposes remotely in 2021. Four hundred examiners were involved in delivering and scoring Standardized Oral Examinations (SOEs) and Objective Structured Clinical Examinations (OSCEs). More than 80% of candidates started their exams on time and stayed connected throughout the exam without any problems. Only 74 (2.5%) SOE and 45 (1.5%) OSCE candidates required rescheduling due to technical difficulties. Of those who experienced "significant issues", concerns with OSCE technical stations (interpretation of monitors and interpretation of echocardiograms) were reported most frequently (6% of candidates). In contrast, 23% of examiners "sometimes" lost connectivity during their multiple exam sessions, on a continuum from minor inconvenience to inability to continue. 84% of SOE candidates and 89% of OSCE candidates described "smooth" interactions with examiners and standardized patients/standardized clinicians, respectively. However, only 71% of SOE candidates and 75% of OSCE candidates considered themselves to be able to demonstrate their knowledge and skills without obstacles. When compared with their in-person experiences, approximately 40% of SOE examiners considered virtual evaluation to be more difficult than in-person evaluation and believed the remote format negatively affected their development as an examiner. The virtual format was considered to be less secure by 56% and 40% of SOE and OSCE examiners, respectively. The retirement of exam materials used virtually due to concern for compromise had implications for subsequent exam development. The return to in-person exams in 2022 was prompted by multiple factors, especially concerns regarding standardization and security. The technology is not yet perfect, especially for testing in-person communication skills and displaying dynamic exam materials. Nevertheless, the American Board of Anesthesiology's experience demonstrated the feasibility of conducting large-scale, high-stakes oral and performance exams in a virtual format and highlighted the adaptability and dedication of candidates, examiners, and administering board staff.

Excess prevalence of preexisting chronic conditions in older adults with incident epilepsy.

OBJECTIVE: Prior studies have examined chronic conditions in older adults with prevalent epilepsy, but rarely among those with incident epilepsy. Identifying the chronic conditions with which older adults present at epilepsy incidence assists with the evaluation of disease burden in this patient population and informs coordinated care development. The aim of this study was to identify preexisting chronic conditions with excess prevalence in older adults with incident epilepsy compared to those without. METHODS: Using a random sample of 4 999 999 fee-for-service Medicare beneficiaries aged >65 years, we conducted a retrospective cohort study of epilepsy incidence in 2019. Non-Hispanic Black and Hispanic beneficiaries were oversampled. We identified preexisting chronic conditions from the 2016-2018 Medicare Beneficiary Summary Files and compared chronic condition prevalence between Medicare beneficiaries with and without incident epilepsy in 2019. We characterized variations in preexisting excess chronic condition prevalence by age, sex, and race/ethnicity, adjusting for the racial/ethnic oversampling. RESULTS: We observed excess prevalence of most preexisting chronic conditions in beneficiaries with incident epilepsy (n = 20 545, weighted n = 19 631). For stroke, for example, the adjusted prevalence rate ratio (APRR) was 4.82 (99% CI:4.60, 5.04), meaning that, compared to those without epilepsy, beneficiaries with incident epilepsy in 2019 had 4.82 times the stroke prevalence. Similarly, beneficiaries with incident epilepsy had a higher prevalence rate for preexisting neurological conditions (APRR = 3.17, 99% CI = 3.08-3.27), substance use disorders (APRR = 3.00, 99% CI = 2.81-3.19), and psychiatric disorders (APRR = 1.98, 99% CI = 1.94-2.01). For most documented chronic conditions, excess prevalence among beneficiaries with incident epilepsy in 2019 was larger for younger age groups compared to older age groups, and for Hispanic beneficiaries compared to both non-Hispanic White and non-Hispanic Black beneficiaries. SIGNIFICANCE: Compared to epilepsy-free Medicare beneficiaries, those with incident epilepsy in 2019 had a higher prevalence of most preexisting chronic conditions. Our findings highlight the importance of health promotion and prevention, multidisciplinary care, and elucidating shared pathophysiology to identify opportunities for prevention.

Prescription Opioids and Brain Structure in Community-Dwelling Older Adults.

OBJECTIVE: To evaluate the associations between prescription opioid exposures in community-dwelling older adults and gray and white matter structure by magnetic resonance imaging. METHODS: Secondary analysis was conducted of a prospective, longitudinal population-based cohort study employing cross-sectional imaging of older adult (≥65 years) enrollees between November 1, 2004, and December 31, 2017. Gray matter outcomes included cortical thickness in 41 structures and subcortical volumes in 6 structures. White matter outcomes included fractional anisotropy in 40 tracts and global white matter hyperintensity volumes. The primary exposure was prescription opioid availability expressed as the per-year rate of opioid days preceding magnetic resonance imaging, with a secondary exposure of per-year total morphine milligram equivalents (MME). Multivariable models assessed associations between opioid exposures and brain structures. RESULTS: The study included 2185 participants; median (interquartile range) age was 80 (75 to 85) years, 47% were women, and 1246 (57%) received opioids. No significant associations were found between opioids and gray matter. Increased opioid days and MME were associated with decreased white matter fractional anisotropy in 15 (38%) and 16 (40%) regions, respectively, including the corpus callosum, posterior thalamic radiation, and anterior limb of the internal capsule, among others. Opioid days and MME were also associated with greater white matter hyperintensity volume (1.02 [95% CI, 1.002 to 1.036; P=.029] and 1.01 [1.001 to 1.024; P=.032] increase in the geometric mean, respectively). CONCLUSION: The duration and dose of prescription opioids were associated with decreased white matter integrity but not with gray matter structure. Future studies with longitudinal imaging and clinical correlation are warranted to further evaluate these relationships.

Understanding the Utility of Less Than Six-Month Prognosis Using Administrative Data Among U.S. Nursing Home Residents With Cancer.

Background: There is a dearth of studies evaluating the utility of reporting prognostication among nursing home (NH) residents with cancer. Objective: To study factors associated with documented less than six-month prognosis, and its relationship with end-of-life (EOL) care quality measures among residents with cancer. Methods: The Surveillance, Epidemiology, and End Results linked with Medicare, and the Minimum Data Set databases was used to identify 20,397 NH residents in the United States with breast, colorectal, lung, pancreatic, or prostate cancer who died between July 2016 and December 2018. Of these, 2205 residents (10.8%) were documented with less than six-month prognosis upon NH admission. Main outcomes were more than one hospitalization, more than one emergency department visit, and any intensive care unit admission within the last 30 days of life as aggressive EOL care markers, as well as admission to hospice, receipt of advance care planning and palliative care, and survival. Specificity and sensitivity of prognosis were assessed using six-month mortality as the outcome. Propensity score matching adjusted for selection biases, and logistic regression examined association. Results: Specificity and sensitivity of documented less than six-month prognosis for mortality were 94.2% and 13.7%, respectively. Residents with documented less than six-month prognosis had greater odds of being admitted to hospice than those without (adjusted odds ratio: 3.27, 95% confidence interval: 2.86-3.62), and lower odds to receive aggressive EOL care. Conclusion: In this cohort study, documented less than six-month prognosis was associated with less aggressive EOL care. Despite its high specificity, however, low sensitivity limits its utility to operationalize care on a larger population of residents with terminal illness.

Racial and Ethnic Disparities in Otolaryngology Office Visit and Tympanostomy Tube Placement in Children with Otitis Media.

OBJECTIVES: Racial disparities are pervasive in access to pediatric surgery. The goal of this study was to test the hypotheses that, compared with White children, non-White and Hispanic children: (1) were less likely to attend evaluations by otolaryngologists after a diagnosis of otitis media (OM) eligible for surgical referral, and (2) these children were less likely to receive tympanostomy tube (TT) after surgical consultation. METHODS: The OptumLabs Data Warehouse is a de-identified claims database of privately insured enrollees. Guidelines on the management of OMs suggest that children should be evaluated for surgery if they have recurrent acute OM or chronic OM with effusion. A cohort of children who were diagnosed with OM were constructed. For Hypothesis 1, the primary outcome was otolaryngology office visit within 6 months of a diagnosis of recurrent or chronic OM. For Hypothesis 2, the outcome was TT placement within 6 months following the otolaryngology office visit. Cox regression models were used to determine the relationship between race/ethnicity and the primary outcomes. RESULTS: Among 187,776 children with OMs, 72,774 (38.8%) had otolaryngology visits. In a multivariate Cox model, the hazard ratios of attending otolaryngology visit for Black, Hispanic, and Asian children were 0.93 (95% CI,0.90, 0.96), 0.86 (0.83, 0.88), and 0.74 (0.71, 0.77), compared with White children. Among the children evaluated by otolaryngologists, 46,554 (63.97%) received TT. Black, Hispanic, and Asian children with recurrent acute OM had lower likelihood of receiving TT. CONCLUSIONS: Racial disparities in attending otolaryngology office visit contributed to the disparities in receiving TT. QUALITY OF EVIDENCE: Level 3 Laryngoscope, 134:3846-3852, 2024.

Effect of Propofol Infusion on Need for Rescue Antiemetics in Postanesthesia Care Unit After Volatile Anesthesia: A Retrospective Cohort Study.

BACKGROUND: Postoperative nausea and vomiting (PONV) are frequent after volatile anesthesia. We hypothesized that coadministration of propofol with volatile anesthetic compared to pure volatile anesthetics would decrease the need for postoperative antiemetic treatments and shorten recovery time in the postanesthesia care unit (PACU). METHODS: We retrospectively identified adult patients who underwent procedures using general anesthesia with volatile agents, with or without propofol infusion, from May 2018 through December 2020, and who were admitted to the PACU. Inverse probability of treatment weighting (IPTW) analysis was performed using generalized estimating equations with robust variance estimates to assess whether propofol was associated with decreased need for rescue antiemetics. RESULTS: Among 47,847 patients, overall IPTW rescue antiemetic use was 4.7% for 17,573 patients who received propofol and 8.2% for 30,274 who did not (odds ratio [OR], 0.55; 95% confidence interval [CI], 0.49-0.61; P <.001). This effect associated with propofol was present regardless of the intensity of antiemetic prophylaxis (OR, 0.59, 0.51, and 0.58 for 0-1, 2, and ≥3 antiemetics used, respectively), procedural duration (OR, 0.54, 0.62, and 0.47 for ≤2.50, 2.51-4.00, ≥4.01 hours), and type of volatile agent (OR, 0.51, 0.52, and 0.57 for desflurane, isoflurane, and sevoflurane) (all P <.001). This effect was dose dependent, with little additional benefit for the reduction in the use of PACU antiemetics when propofol rate exceeded 100 µg/kg/min. Patients who received rescue antiemetics required longer PACU recovery time than those who did not receive antiemetics (ratio of the geometric mean, 1.31; 95% CI, 1.28-1.33; P <.001), but use of propofol did not affect PACU recovery time (ratio of the geometric mean, 1.00; 95% CI, 0.98-1.01; P =.56). CONCLUSIONS: The addition of propofol infusions to volatile-based anesthesia is associated with a dose-dependent reduction in the need for rescue antiemetics in the PACU regardless of the number of prophylactic antiemetics, duration of procedure, and type of volatile agent used, without affecting PACU recovery time.

Baseline Participant Characteristics at Enrollment in the Zoster Eye Disease Study.

PURPOSE: The Zoster Eye Disease Study (ZEDS) is the first randomized clinical trial to study the efficacy of long-term (1 year) suppressive valacyclovir treatment on herpes zoster ophthalmicus (HZO) outcomes. This article details the baseline characteristics of participants. SETTING: The study was set at 95 participating clinical centers in 33 states, Canada, and New Zealand. STUDY POPULATION: Immunocompetent adults with a history of a characteristic HZO unilateral rash and documentation of an episode of active dendriform epithelial keratitis, stromal keratitis, endothelial keratitis, or iritis within the preceding year, enrolled in ZEDS from November 2017 to January 2023. INTERVENTION: Participants were randomized to double-masked oral valacyclovir 1 gm daily versus placebo for 1 year of treatment and followed for 18 months. RESULTS: Five hundred twenty-seven participants were enrolled across 4 strata according to age at HZO onset (younger or older than 60 years) and duration of HZO at enrollment (less or greater than 6 months), with an even distribution of men and women and a median age of 60 years. More participants with recent (57%, 300/527) than chronic HZO and younger than 60 years at HZO onset (54%, 286/527) were enrolled. Most participants were treated acutely with a recommended antiviral regimen (91%, 480/527) and had not been vaccinated against zoster (79%, 418/527). CONCLUSIONS: The broad ZEDS study population enhances the likelihood that ZEDS will provide generalizable high-quality evidence regarding the efficacy and safety of suppressive valacyclovir for HZO immunocompetent adults and whether it should become standard of care. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03134196.

Transfusion targets and adverse events in pediatric perioperative acute Anemia.

STUDY OBJECTIVE: To evaluate the association between pretransfusion and posttransfusion hemoglobin concentrations and the outcomes of children undergoing noncardiac surgery. DESIGN: Retrospective review of patient records. We focused on initial postoperative hemoglobin concentrations, which may provide a more useful representation of transfusion adequacy than pretransfusion hemoglobin triggers (the latter often cannot be obtained during acute surgical hemorrhage). SETTING: Single-center, observational cohort study. PATIENTS: We evaluated all pediatric patients undergoing noncardiac surgery who received intraoperative red blood cell transfusions from January 1, 2008, through December 31, 2018. INTERVENTIONS: None. MEASUREMENTS: Associations between pre- and posttransfusion hemoglobin concentrations (g/dL), hospital-free days, intensive care unit admission, postoperative mechanical ventilation, and infectious complications were evaluated with multivariable regression modeling. MAIN RESULTS: In total, 113,713 unique noncardiac surgical procedures in pediatric patients were evaluated, and 741 procedures met inclusion criteria (median [range] age, 7 [1-14] years). Four hundred ninety-eight patients (68%) with a known preoperative hemoglobin level had anemia; of these, 14% had a preexisting diagnosis of anemia in their health record. Median (IQR) pretransfusion hemoglobin concentration was 8.1 (7.4-9.2) g/dL and median (IQR) initial postoperative hemoglobin concentration was 10.4 (9.3-11.6) g/dL. Each decrease of 1 g/dL in the initial postoperative hemoglobin concentration was associated with increased odds of transfusion within the first 24 postoperative hours (odds ratio [95% CI], 1.62 [1.37-1.93]; P < .001). No significant relationships were observed between postoperative hemoglobin concentrations and hospital-free days (P = .56), intensive care unit admission (P = .71), postoperative mechanical ventilation (P = .63), or infectious complications (P = .74). CONCLUSIONS: In transfused patients, there was no association between postoperative hemoglobin values and clinical outcomes, except the need for subsequent transfusion. Most transfused patients presented to the operating room with anemia, which suggests a potential opportunity for perioperative optimization of health before surgery.

Novel endoscopic scoring system for immune mediated colitis: a multicenter retrospective study of 674 patients.

BACKGROUND AND AIMS: No endoscopic scoring system has been established for immune-mediated colitis (IMC). This study aimed to establish such a system for IMC and explore its utility in guiding future selective immunosuppressive therapy (SIT) use compared to clinical symptoms. METHODS: This retrospective, international, 14-center study included 674 patients who developed IMC after immunotherapy and underwent endoscopic evaluation. Ten endoscopic features were selected by group consensus and assigned 1 point each to calculate an IMC endoscopic score (IMCES). IMCES cutoffs were chosen to maximize specificity for SIT use. This specificity was compared between IMCESs, and clinical symptoms were graded according to a standardized instrument. RESULTS: A total of 309 (45.8%) patients received SIT. IMCES specificity for SIT use was 82.8% with a cutoff of 4. The inclusion of ulceration as a mandatory criterion resulted in higher specificity (85.0% for a cutoff of 4). In comparison, the specificity of a Mayo endoscopic subscore of 3 was 74.6%, and the specificity of clinical symptom grading was much lower at 27.4% and 12.3%, respectively. Early endoscopy was associated with timely SIT use (P < .001; r = 0.4084). CONCLUSIONS: This is the largest multicenter study to devise an endoscopic scoring system to guide IMC management. An IMCES cutoff of 4 has a higher specificity for SIT use than clinical symptoms, supporting early endoscopic evaluation for IMC.

Predicting Hospital Survival in Patients Admitted to ICU with Pulmonary Embolism.

OBJECTIVE: The Pulmonary Embolism Severity Index (PESI) and simplified PESI (sPESI) predict mortality for patients with PE. We compared PESI/sPESI to the Acute Physiology and Chronic Health Evaluation IV (APACHE-IV) in predicting mortality in patients with PE admitted to the intensive care unit (ICU). Additionally, we assessed the performance of a novel ICU-sPESI score created by adding three clinical variables associated with acuity of PE presentation (intubation, confusion [altered mental status], use of vasoactive infusions) to sPESI. MATERIALS AND METHODS: Using the eICU Collaborative Research Database from 2014 to 2015, we conducted a large retrospective cohort study of adult patients admitted to the ICU with a primary diagnosis of PE. We calculated APACHE-IV, PESI, sPESI, and ICU-sPESI scores and compared their performance for predicting in-hospital mortality using area under the receiver operating characteristic (AUROC) curve. Score thresholds for >99% negative predictive values (NPV) were calculated for each score. Survival was estimated using the Kaplan-Meier method. RESULTS: We included 1424 PE cases. In-hospital mortality was 6.3% [95% CI: 5.1%-7.6%]. AUROC for APACHE-IV, PESI, and sPESI were 0.870, 0.848, and 0.777, respectively. APACHE-IV and PESI outperformed sPESI (P < 0.01 for both comparisons), while APACHE-IV and PESI demonstrated similar performance (P = 0.322). The ICU-sPESI performance was similar to APACHE-IV and PESI (AUROC = 0.847; AUROC comparison: APACHE-IV vs ICU-sPESI: P = 0.396; PESI vs ICU-sPESI: P = 0.945). Hospital mortality for ICU-sPESI scores 0-2 was 1.1%, and for scores 3, 4, 5, 6, and ≥7 was 8.6%, 11.7%, 29.2%, 37.5%, and 76.9%, respectively. Score thresholds for >99% NPV were ≤48 for APACHE-IV, ≤115 for PESI, and 0 points for sPESI and ICU-sPESI. CONCLUSIONS: By accounting for severity of PE presentation, our newly proposed ICU-sPESI score provided improved PE mortality prediction compared to the original sPESI score and offered excellent discrimination of mortality risk.

Comparing characteristics and perspectives of U.S. anesthesiology fellows in training and anesthesiologists in their first year of practice.

BACKGROUND: The purpose of this study was to evaluate relationships between demographics, professional characteristics, and perceived challenges facing the specialty of anesthesiology among physicians who entered a fellowship and those who started independent practice immediately after finishing a U.S. anesthesiology residency. METHODS: Anesthesiologists in the year after their residency graduation were invited to take an online survey during the academic years of 2016-2017, 2017-2018, and 2018-2019, with questions about their personal characteristics, the nature of their professional lives, and their perceptions of the greatest challenge facing the profession of anesthesiology. RESULTS: A total of 884 fellows-in-training and 735 anesthesiologists starting independent practice right after the completion of their residency responded. Fellows were slightly younger (mean = 33.2 vs. 34.0 years old, p < 0.001), were more likely to have a spouse who works outside the home (63.9% vs. 57.0%, p = 0.002), had fewer children (mean = 0.69 vs. 0.88, p < 0.001), worked more hours per week (mean = 56.2 vs. 52.4, p < 0.001), and were less likely to report a personal and professional life balance (66.4% vs. 72.3% positive, p = 0.005) than direct-entry anesthesiologists. Fellows and direct-entry anesthesiologists identified similar challenges in three broad themes - workforce competition (80.3% and 71.8%), healthcare system changes (30.0% and 37.9%), and personal challenges (6.4% and 8.8%). Employment security issues posed by non-physician anesthesia providers and perceived lack of appreciation of anesthesiologists' value were commonly cited. Relative weighting of challenge concerns varied between fellows and direct-entry physicians, as well as within these groups based on gender, fellowship subspecialty, location or size of practice, and frequency of supervisory roles. CONCLUSIONS: Anesthesiology fellows and direct-entry anesthesiologists had largely similar demographics and perspectives on the challenges facing anesthesiology in the United States. Group differences found in some demographics and perspectives may reflect different motivations for choosing their professional paths and their diverse professional experiences.

Qualitative Assessment of Perioperative Lactation Patient Education: "I Think It's Something Women Navigate on Their Own".

Background: Patients who are lactating at the time of a procedure requiring anesthesia benefit from specific education and care coordination to support continued lactation and avoid complications. Before design and implementation of a comprehensive care pathway for this patient population at our institution, we sought to elicit the patient perspective. Methods: We conducted semistructured qualitative interviews with eight patients by phone regarding their experience as a lactating patient presenting for a procedure with anesthesia care at our institution. These were analyzed for predominant themes regarding their experiences. Results: The patients we interviewed reported receiving conflicting information and feeling a sense of uncertainty. Some patients experienced preventable health effects such as mastitis, and prior experience with breastfeeding was protective. The interviewed patients endorsed a desire for structured support and improved education resources. Discussion: This qualitative study of lactating patients undergoing anesthesia and surgery demonstrates a need for coordinated perioperative lactation care. A structured pathway for this patient population with access to updated care guidelines and patient education would be welcomed.

Intracarotid Infusion of Redox-Active Manganese Porphyrin, MnTnBuOE-2-PyP5+, following Reperfusion Improves Long-Term, 28-Day Post-Stroke Outcomes in Rats.

Endovascular mechanical thrombectomy, combined with a tissue plasminogen activator (t-PA), is efficacious as a standard care for qualifying ischemic stroke patients. However, > 50% of thrombectomy patients still have poor outcomes. Manganese porphyrins, commonly known as mimics of superoxide dismutases, are potent redox-active catalytic compounds that decrease oxidative/nitrosative stress and in turn decrease inflammatory responses, mitigating therefore the secondary injury of the ischemic brain. This study investigates the effect of intracarotid MnTnBuOE-2-PyP5+ (BMX-001) administration on long-term, 28-day post-stroke recovery in a clinically relevant setting. The 90 min of transient middle cerebral artery occlusion was performed in young, aged, male, female, and spontaneous hypertension rats. All physiological parameters, including blood pressure, blood gas, glucose, and temperature, were well controlled during ischemia. Either BMX-001 or a vehicle solution was infused through the carotid artery immediately after the removal of filament, mimicking endovascular thrombectomy, and was followed by 7 days of subcutaneous injection. Neurologic deficits and infarct volume were assessed at 28 days in a blinded manner. The effects of BMX-001 on the carotid arterial wall and blood-brain barrier permeability and its interaction with t-PA were assessed in normal rats. There were no intra-group differences in physiological variables. BMX-001-treated stroke rats regained body weight earlier, performed better in behavioral tests, and had smaller brain infarct size compared to the vehicle-treated group. No vascular wall damage and blood-brain barrier permeability changes were detected after the BMX-001 infusion. There was no drug interaction between BMX-001 and t-PA. Intracarotid BMX-001 infusion was safe, and it significantly improved stroke outcomes in rats. These findings indicate that BMX-001 is a candidate drug as an adjunct treatment for thrombectomy procedure to further improve the neurologic outcomes of thrombectomy patients. This study warrants further clinical investigation of BMX-001 as a new stroke therapy.
