Impact of COVID-19 pandemic and vaccine perceptions on HPV vaccine hesitancy.

OBJECTIVE: This study evaluated the impact of the COVID-19 pandemic and vaccine perceptions on Human Papillomavirus (HPV) vaccine hesitancy. Secondary endpoints included comparing COVID-19 and HPV vaccination trends regarding time, community of residence, and unmet social needs. METHODS: This was a survey-based, cross-sectional study that included 101 participants who were recruited through the Wyandotte County Public Health Department. Participants were eligible for inclusion in this study if they were a parent/guardian of one or more children aged 13 to 17; English- or Spanish-speaking. This study took place in Wyandotte County, Kansas. Descriptive statistics and chi-square analyses were utilized. RESULTS: There was no difference in completion of COVID-19 and HPV vaccines (p = 0.0975). Significantly more individuals started and did not finish the HPV vaccine series compared to the COVID-19 vaccine series (p = 0.0004). Most participants indicated their opinion on the HPV vaccine had not changed due to the pandemic (71.3 %). Participants who felt familiar with HPV had higher rates of HPV vaccine completion. While 77 % of participants felt extremely or moderately familiar with HPV, 61.4 % were unaware of its association with oropharyngeal cancer. CONCLUSION: There was minimal change in parents' perception of the HPV vaccine due to the COVID-19 pandemic despite decreased rates of vaccination during this time. HPV vaccine series completion was significantly lower than COVID-19 vaccine series completion, highlighting a need to improve HPV vaccine completion counseling. Additionally, patient education should address the knowledge gap discovered regarding the link between HPV infection and oropharyngeal cancer.

High-intensity focused ultrasound for benign thyroid nodules: Systemic review and meta-analysis.

BACKGROUND: High-intensity focused ultrasound (HIFU) is a less invasive option offered for the treatment of large, compressive, benign thyroid nodules. METHODS: Observational studies of more than five participants using HIFU in the management of benign thyroid nodules from 2000 to 2021 were identified using predefined inclusion criteria. The primary outcome was an estimate of the effectiveness of HIFU. RESULTS: Out of 158 studies reviewed, 8 articles were included with 297 patients and 300 nodules. HIFU significantly reduced nodule volume from 1 to 24 months following therapy (weighted mean difference [WMD], 47.68, 95 % confidence interval [CI], 34.13-59.66, p < 0.0001) and achieved favorable success rates (risk ratio [RR], 1.49, 95 % CI, 1.15-1.84, p < 0.001) for 50 % volume reduction. CONCLUSIONS: HIFU appears to be a feasible, safe, and effective treatment modality for patients with benign thyroid nodules. Future research, including randomized controlled trials, is needed to determine therapy optimization, and patient selection to identify the potential role of this new therapy.

Botox for the prevention of radiation-induced Sialadenitis and xerostomia in head and neck cancer patients: A pilot study.

BACKGROUND: To determine the safety of Botox and its potential effect on alleviating radiation therapy (RT)-induced sialadenitis in head and neck cancer patients. METHODS: Twenty patients with stage III/IV head and neck cancer were randomized to receive Botox or saline injections into both submandibular glands (SMG). There were three visits: one before RT (V1); 1 week after RT (V2); and 6 weeks after RT (V3), each of which included saliva collection, a 24-h dietary recall, and a quality-of-life survey. RESULTS: No adverse events were observed. While the control group was much older, the Botox group more commonly underwent induction chemotherapy compared with controls. From V1 to V2, salivary flow decreased in both groups, but only in the control group from V1 to V3. CXCL-1 (GRO), a neutrophil chemoattractant, was lower in the Botox group compared with the control group at V3. CONCLUSION: Botox can be safely administered to the salivary glands prior to external beam radiation without observed complications or side-effects. After an initial reduction in salivary flow following RT, the Botox group showed lack of further flow reduction compared with controls. The inflammatory marker CXCL 1, which was reduced in the in Botox group at V3, may be a candidate for further studies of radiation-induced sialadenitis.

Pathology education project (PEP): A pilot program to spark student understanding in pathology as a career.

According to the National Resident Matching Program in 2022, 631 pathology positions were offered. In total, 248 senior applicants from United States (US) allopathic schools filled 36.6% of these positions. To bolster medical student understanding of pathology, a medical school pathology interest group organized a multi-day activity to introduce rising second-year medical students to pathology as a career. Five students completed both pre- and post-activity surveys assessing their knowledge of the specialty. All five students had a BA/BS degree as their highest level of education. Only one student indicated that he or she had previously shadowed a pathologist as a medical laboratory scientist for a duration of four years. Two students indicated that they were interested in internal medicine, one indicated radiology, one forensic pathology or radiology, and one was undecided. During the activity, students biopsied tissue from cadavers in the gross anatomy lab. Thereafter, students participated in the standard tissue processing by shadowing a histotechnologist. Under the guidance of a pathologist, students microscopically examined slides and discussed the clinical findings. Post-activity survey results indicated that participation increased their knowledge of pathology as a career with a median increase of 0.8 points (range: 0.2 to 1.6) on a 5-point Likert scale. Students also indicated that their participation increased their knowledge of pathology skills and techniques-median increase of 1.2 (range: 0.8 to 1.8). This activity can be implemented by medical educators to expose medical students to pathology as a career with the benefit of increasing student knowledge in the specialty.

The effect of curricular reform on gross anatomy laboratory examination performance: An institutional analysis.

Many medical schools have undergone curricular reform recently. With these reforms, time spent teaching anatomy has been reduced, and there has been a general shift to a pass/fail grading system. At Indiana University School of Medicine (IUSM), a new curriculum was implemented in fall 2016. The year-long human gross anatomy course taught in 2015 was condensed into an integrated, semester-long course starting in 2016. Additionally, the grading scale shifted to pass/fail. This study examined first-year medical student performance on anatomy practical laboratory examinations-specifically, among lower-order (pure identification) questions and higher-order (function, innervation) questions. Participants included medical students from a pre-curricular reform cohort (year 2015, 34 students) and two post-curricular reform cohorts (years 2016, 30 students and 2017, 33 students). A Kruskal-Wallis ANOVA test was used to determine differences of these questions among the three cohorts. Additionally, 40 of the same lower-order questions that were asked on gross anatomy laboratory examinations from medical student cohort year 2015 and year 2016 were further analyzed using an independent samples t-test. Results demonstrated that the pre-curricular reform cohort scored significantly higher on both lower-order (median = 81, p < 0.001) and higher-order questions (median = 82.5, p < 0.05) than both post-curricular reform cohorts. Additionally, when reviewing the selected 40 similar questions, it was found that the pre-curricular reform cohort averaged significantly higher (82.1 ± 16.1) than the post-curricular reform cohort from 2016 (69.3 ± 21.8, p = 0.004). This study provides evidence about the impact of curricular reform on medical student anatomical knowledge.

A 10-mg dose of amiloride increases time to failure during blood-flow-restricted plantar flexion in healthy adults without influencing blood pressure.

Amiloride has been shown to inhibit acid-sensing ion channels (ASICs), which contribute to ischemia-related muscle pain during exercise. The purpose of this study was to determine if a single oral dose of amiloride would improve exercise tolerance and attenuate blood pressure during blood-flow-restricted (BFR) exercise in healthy adults. Ten subjects (4 females) performed isometric plantar flexion exercise with BFR (30% maximal voluntary contraction) after ingesting either a 10-mg dose of amiloride or a volume-matched placebo (random order). Time to failure, time-tension index (TTI), and perceived pain (visual analog scale) were compared between the amiloride and placebo trials. Mean blood pressure, heart rate, blood pressure index (BPI), and BPI normalized to TTI (BPInorm) were also compared between trials using both time-matched (TM50 and TM100) and effort-matched (T50 and T100) comparisons. Time to failure (+69.4 ± 63.2 s, P < 0.01) and TTI (+1,441 ± 633 kg·s, P = 0.02) were both significantly increased in the amiloride trial compared with placebo, despite no increase in pain (+0.4 ± 1.7 cm, P = 0.46). In contrast, amiloride had no significant influence on the mean blood pressure or heart rate responses, nor were there any significant differences in BPI or BPInorm between trials when matched for time (all P ≥ 0.13). When matched for effort, BPI was significantly greater in the amiloride trial (+5,300 ± 1,798 mmHg·s, P = 0.01), likely owing to an increase in total exercise duration. In conclusion, a 10-mg oral dose of amiloride appears to significantly improve the tolerance to BFR exercise in healthy adults without influencing blood pressure responses.

A is for Airway: An Interprofessional Simulation Event to Re-Establish the Importance of Communication.

Establishing an airway in the operating room is an interdisciplinary activity that requires focus of all participants. An interprofessional simulation event was designed to reestablish the importance of this OR event for student registered nurse anesthetists and registered nurse first assists.

Repeated warm water baths decrease sympathetic activity in humans.

Acute whole body heat stress evokes sympathetic activation. However, the chronic effects of repeated moderate heat exposure (RMHE) on muscle sympathetic nerve activity (MSNA) in healthy individuals remain unclear. We performed RMHE with 4 wk (5 days/wk) of warm baths (∼40°C, for 30 min) in nine healthy older (59 ± 2 yr) volunteers. Hemodynamic variables and MSNA were examined before, 1 day after, and 1 wk following 4 wk of RMHE in a laboratory at ∼23°C. Cold pressor test (CPT) and handgrip (HG) exercise were performed during the tests. Under normothermic condition, the resting MSNA burst rate (prior, post, post 1-wk: 31.6 ± 2.0, 25.2 ± 2.0, and 27.7 ± 1.7 bursts/min; P < 0.001) and burst incidence (P < 0.001) significantly decreased after RMHE. Moreover, the resting heart rate significantly decreased after RMHE (62 ± 2, 60 ± 2, and 58 ± 2 beats/min, P = 0.031). The sensitivity of baroreflex control of MSNA and heart rate were not altered by RMHE, although the operating points were reset. The MSNA and hemodynamic responses (i.e., changes) to handgrip exercise or cold pressor test were not significantly altered. These data suggest that the RMHE evoked by warm baths decreases resting sympathetic activity and heart rate, which can be considered beneficial effects. The mechanism(s) should be examined in future studies.NEW & NOTEWORTHY To our knowledge, this is the first study to observe the effects of repeated warm baths on sympathetic nerve activity during rest and stress in healthy middle age and older individuals. The data suggest that the repeated warm baths decreased resting sympathetic activity and heart rate, which can be considered beneficial effects. This study also provides the first evidence that the repeated warm baths did not alter the baroreflex sensitivity and the sympathetic responses to stress.

Multiple Laser Doppler Flowmetry Probes Increase the Reproducibility of Skin Blood Flow Measurements.

Cutaneous microcirculatory perfusion is commonly measured using laser Doppler flowmetry (LDF) probes, which provide a continuous, non-invasive quantification of skin blood flow (SkBF). However, inhomogeneities in the skin's microvasculature density contribute to a decrease in reproducibility whenever an LDF probe is removed and replaced, as is the case during pre- and post-intervention or between-day measurements. Therefore, this study aimed to determine whether increasing the total number of individual LDF probes in a localized area improves the reproducibility of the measurement. Seven laser Doppler probes were secured in a custom-made acrylic holder designed to attach to the skin's surface easily. SkBF, local skin temperature (Tsk), and blood pressure (BP) were assessed in 11 participants (6 M, 5 F, 42 ± 15 years). SkBF and Tsk were measured from the dorsal forearm (arm trial) for 5 min. Next, the multi-laser device was moved to the lateral side of the calf (leg trial), and measurements were obtained for 5 min. Each arm and leg trial was cyclically repeated three times, and all trials were separated by intermissions lasting 10-15 min. The average SkBF and the cutaneous vascular conductance (CVC) from all possible LDF probe combinations were not statistically different across the three arm and leg trials. Two-way mixed-effects models with absolute agreement were used to compute the intraclass correlation coefficient (ICC) for CVC, and the minimum ICC increased with the addition of LDF probes. The ICC of the average CVC from seven LDF probes was 0.96 between the arm trials and 0.91 between the leg trials, which suggests that there is excellent reliability and little difference between trials following the removal and replacement of the device. Moreover, all individual ICC values from ≥3 LDF probe combinations were greater than 0.70 (i.e., good reliability). These data suggest that SkBF measurements with multiple laser Doppler probes in a custom-made holder have excellent reproducibility after replacing the probes within the same participant. Therefore, this application could provide more reproducible assessments between repeated measurements (e.g., before and after exercise or clinical procedures) where the LDF probes must be removed and replaced within the same location.

Approaching trauma analgesia using prolonged and novel continuous peripheral nerve blocks - A case report.

BACKGROUND: A supraclavicular brachial plexus nerve block provides analgesia for the shoulder, arm, and hand; however, the maximum safe duration for a continuous infusion remains controversial. A novel continuous peripheral nerve block (CPNB) technique combining the Lateral, Intermediate, and Medial femoral cutaneous nerves (termed the 'LIM' block) to provide analgesia to the lateral, anterior, and medial cutaneous areas of the thigh while preserving quadriceps strength will also be described in detail here. CASE: We present a complex case in which simultaneous utilization of an unilateral supraclavicular CPNB (5 weeks) and bilateral LIM CPNB (5 days) are successfully performed to provide analgesia for a traumatic degloving injury resulting in multiple surgeries. CONCLUSIONS: The analgesic plan in this case study eliminated previous episodes of opioid-induced delirium, facilitated participation in recovery, and removed concerns for respiratory depression and chronic opioid use in a patient at particular risk for both issues.

The effect of nutritional status on post-operative outcomes in pediatric otolaryngology-head and neck surgery.

INTRODUCTION: Nutritional status can affect surgical patients in terms of stress response, healing time, and outcomes. Several abnormalities are known to have a high prevalence in the general population such as vitamin D deficiency (VDD) and subclinical hypothyroidism. We hypothesized that there will be elevated rates of nutritional deficiencies in preoperative patients which may adversely affect postoperative outcomes following pediatric otolaryngology surgery. METHODS: IRB approval was obtained for a cross-sectional cohort study. Consecutive patients underwent nutritional evaluation when being scheduled for surgery including TSH, albumin and vitamin D. Demographic data, supplementation, and early complication rates were collected. RESULTS: 125 patients were included in the final cohort with adequate demographic distribution. Based on anthropometric data, 12% of our cohort was found to be undernourished, and 40% of our cohort with elevated BMI. However, there was no relationship found between Z-scores and complications. VDD was noted in 83/125 (66.4%) patients. Our cohort had increased rates of VDD in patients with elevated BMI and African American ethnicity. Thyroid hormone abnormalities were present in 12 patients. Mean serum albumin level was 4.29 in our cohort all within normal range. We did find increased risk of postoperative complications in patients with previously diagnosed comorbidities. (p=0.006). CONCLUSION: There is no current recommendation or consensus for nutritional assessment in preoperative pediatric patients. Our study did not show statistically significant correlation with z-scores, low vitamin D levels with supplementation, albumin, or TSH to postoperative complications. However, our patient cohort had higher than average rates of VDD compared to the many studies of the general pediatric population and significant negative correlation between vitamin D levels and z-scores. By early preoperative identification of VDD and supplementation with calciferol, we found no significant difference in complication rates in patients based on their initial vitamin D status. We suggest screening preoperative patients using z-score calculations and vitamin D levels based on individual patient risk factors including atrisk patient populations such as African American children, and obese children.

Diffusion tensor imaging indices of acute muscle damage are augmented after exercise in peripheral arterial disease.

PURPOSE: Although it is known that peripheral arterial disease (PAD) is associated with chronic myopathies, the acute muscular responses to exercise in this population are less clear. This study used diffusion tensor imaging (DTI) to compare acute exercise-related muscle damage between PAD patients and healthy controls. METHODS: Eight PAD patients and seven healthy controls performed graded plantar flexion in the bore of a 3T MRI scanner. Exercise began at 2 kg and increased by 2 kg every 2 min until failure, or completion of 10 min of exercise. DTI images were acquired from the lower leg pre- and post-exercise, and were analyzed for mean diffusivity, fractional anisotropy (FA), and eigenvalues 1-3 (λ1-3) of the medial gastrocnemius (MG) and tibialis anterior (TA). RESULTS: Results indicated a significant leg by time interaction for mean diffusivity, explained by a significantly greater increase in diffusivity of the MG in the most affected legs of PAD patients (11.1 × 10-4 ± 0.5 × 10-4 mm2/s vs. 12.7 × 10-4 ± 1.2 × 10-4 mm2/s at pre and post, respectively, P = 0.02) compared to healthy control subjects (10.8 × 10-4 ± 0.3 × 10-4 mm2/s vs. 11.2 × 10-4 ± 0.5 × 10-4 mm2/s at pre and post, respectively, P = 1.0). No significant differences were observed for the TA, or λ1-3 (all P ≥ 0.06). Moreover, no reciprocal changes were observed for FA in either group (all P ≥ 0.29). CONCLUSION: These data suggest that calf muscle diffusivity increases more in PAD patients compared to controls after exercise. These findings are consistent with the notion that acute exercise results in increased muscle damage in PAD.

Resident operative experience in pediatric neurosurgery across the United States.

OBJECTIVE: Neurosurgical residents receive exposure to the subspecialty of pediatric neurosurgery during training. The authors sought to determine resident operative experience in pediatric neurosurgery across Accreditation Council for Graduate Medical Education (ACGME)-accredited neurosurgical programs. METHODS: During 2018-2019, pediatric neurosurgical case logs for recent graduates or current residents who completed their primary pediatric exposure were collected from US continental ACGME training programs. Using individual resident reports and procedure designations, operative volumes and case diversity were analyzed collectively, according to training site characteristics, and also correlated with the recently described Resident Experience Score (RES). RESULTS: Of the 114 programs, a total of 316 resident case logs (range 1-19 residents per program) were received from 86 (75%) programs. The median cumulative pediatric case volume per resident was 109 (IQR 75-161). Residents at programs with a pediatric fellowship reported a higher median case volume (143, IQR 96-187) than residents at programs without (91, IQR 66-129; p < 0.0001). Residents at programs that outsource their pediatric rotation had a lower median case volume (84, IQR 52-114) compared with those at programs with an in-house experience (117, IQR 79-170; p < 0.0001). The case diversity index among all programs ranged from 0.61 to 0.80, with no statistically significant differences according to the Accreditation Council for Pediatric Neurosurgery Fellowships designation or pediatric experience site (p > 0.05). The RES correlated moderately (r = 0.44) with median operative volumes per program. A program's annual pediatric operative volume and duration of pediatric experience were identified as significant predictive factors for median resident operative volume. CONCLUSIONS: Resident experience in pediatric neurosurgery is variable within and between programs. Case volumes are generally higher for residents at programs with in-house exposure and an accredited fellowship, but case diversity is relatively uniform across all programs. RES provides some insight on anticipated case volume, but other unexplained factors remain.

Comprehensive Comparison of Right and Left Recurrent Laryngeal Nerves in the Tracheoesophageal Groove.

OBJECTIVE: A left-sided cervical approach to esophageal mobilization is considered safer given the perceived oblique path and more lateral orientation of the right recurrent laryngeal nerve (RLN) in the tracheoesophageal groove. Given the risk of recurrent laryngeal nerve, the current study investigated if there are differences in right and left RLN location in the tracheoesophageal groove. METHODS: Right and left RLNs were carefully exposed in human cadavers. Comparison of location was determined at tracheal rings 2, 4, and 6 using 3 parameters: depth of the RLN from the anterior margin of the tracheal ring, lateral distance of the RLN from the posterior margin of the tracheal ring, and distance of the RLN to the anterior midline trachea following the curvature of the trachea. Statistical analysis was used to determine differences between the right and left sides. RESULTS: Compared with the right RLN, the left RLN was slightly over 1 mm deeper at the second tracheal ring. Despite this trend, there was no significant difference in RLN location between individual sides or as an aggregate for any of the 3 parameters at tracheal rings 2, 4, or 6. CONCLUSIONS: Careful characterization of RLN location precludes avoiding hoarseness, aphonia, and vocal cord paralysis. Counter to common surgical perception and educational beliefs, this study demonstrated that right and left RLN anatomical courses do not significantly differ along the trachea. Therefore, ensnarement on either side during a blind mobilization of the cervical esophagus is equally likely to occur.

Renal medullary oxygenation decreases with lower body negative pressure in healthy young adults.

One in three Americans suffer from kidney diseases such as chronic kidney disease, and one of the etiologies is suggested to be long-term renal hypoxia. Interestingly, sympathetic nervous system activation evokes a renal vasoconstrictor effect that may limit oxygen delivery to the kidney. In this report, we sought to determine if sympathetic activation evoked by lower body negative pressure (LBNP) would decrease cortical and medullary oxygenation in humans. LBNP was activated in a graded fashion (LBNP; -10, -20, and -30 mmHg), as renal oxygenation was measured (T2*, blood oxygen level dependent, BOLD MRI; n = 8). At a separate time, renal blood flow velocity (RBV) to the kidney was measured (n = 13) as LBNP was instituted. LBNP significantly reduced RBV (P = 0.041) at -30 mmHg of LBNP (Δ-8.17 ± 3.75 cm/s). Moreover, both renal medullary and cortical T2* were reduced with the graded LBNP application (main effect for the level of LBNP P = 0.0008). During recovery, RBV rapidly returned to baseline, whereas medullary T2* remained depressed into the first minute of recovery. In conclusion, sympathetic activation reduces renal blood flow and leads to a significant decrease in oxygenation in the renal cortex and medulla.NEW & NOTEWORTHY In healthy young adults, increased sympathetic activation induced by lower body negative pressure, led to a decrease in renal cortical and medullary oxygenation measured by T2*, a noninvasive magnetic resonance derived index of deoxyhemoglobin levels. In this study, we observed a significant decrease in renal cortical and medullary oxygenation with LBNP as well as an increase in renal vasoconstriction. We speculate that sympathetic renal vasoconstriction led to a significant reduction in tissue oxygenation by limiting oxygen delivery to the renal medulla.

Injection Laryngoplasty for the Treatment of Type 1 Laryngeal Clefts: A Single Institution Experience.

OBJECTIVE: Standards for treatment of laryngeal clefts remain poorly defined. There are no large case series that report the efficacy of injection laryngoplasty (IL) in the treatment of pediatric Type 1 laryngeal clefts (LC-1). The objective of this study is to measure the effect of IL in young children with LC-1. METHODS: A retrospective case series of 130 patients was completed over 3 years at a at a single institution included patients aged 1 month to 8 years, diagnosed with aspiration and penetration issues during swallowing based on a Videofluoroscopic Swallow Study (VFSS). Patients underwent surgical evaluation and intervention using carboxymethylcellulose gel injection. Collected data points included age in months at time of first injection, gender, race, pre- and post-operation VFSS scores, number of injections, co-morbidities and post-operative complications. VFSS scores were evaluated pre- and post-operatively to assess efficacy of intervention. A secondary outcome was efficacy in patients with aspiration compared to those with penetration alone. RESULTS: This study included 77 male and 53 female patients. Sixty-two patients (48%) demonstrated a significant post-operative improvement in their swallowing function (P < .05). There were no statistical differences in age, number of injections, or the volume of the first injection. Patients that showed a post-operative improvement in swallowing function were on average 5 months older and had more severe aspiration and penetration compared to those who did not demonstrate a post-operative benefit and underwent less injections. The volume of injection did not appear to play a role in the success rate. CONCLUSION: Injecting the inter-arytenoid area in patients with LC-1 appears to confer some benefit to close to half of our patient population. Successful procedures seemed to occur in patients with more severe aspiration and penetration and older age.

Erosion of a right ventricular pacer lead into the left chest wall.

BACKGROUND: Erosion of a pacer lead into the chest wall may result in pericardial effusion with cardiac tamponade. Free rupture into the pleura or mediastinum can result in hypotension and cardiac arrest. CASE PRESENTATION: We report a unique case of a right ventricular pacer lead which eroded through the right ventricle into the left chest wall and penetrated a rib. The patient presented with a tender chest wall mass without pericardial or pleural effusion. The segment of rib which the pacing lead had penetrated was removed. CONCLUSIONS: The patient tolerated the procedure well and was discharged 1 week after the operation. This case adds to the current literature the justification of removal of temporary and non-functional pacing leads.

An Interprofessional Branching Simulation to Introduce RN First Assistant Students to Their Role in the Perioperative Setting.

Simulation can be an effective tool for educating health profession students and can enhance interprofessional education by involving roles across multiple disciplines. Perioperative nurse educators at one institution used a five-part branching simulation of preoperative, intraoperative, and postoperative events for a single patient undergoing a procedure to introduce RN first assistant (RNFA) students to their role in the perioperative environment. The simulation participants included student RN anesthetists, a surgeon, an RN circulator (played by an actor), and a standardized patient. The objectives for this simulation were to assess the implementation of the didactic RNFA curriculum and to enhance the RNFA students' transition into their role in the perioperative setting. The simulation and multiple debriefings reinforced the concepts of role acquisition, surgical conscience, closed-loop communication, and interprofessional collaboration. Perioperative nurse educators can use this type of educational activity to teach these concepts to their students.

Dissecting the Financial Relationship Between Industry and Academic Neurosurgery.

BACKGROUND: Established by the Centers for Medicare and Medicaid Services (CMS), the Open Payments Database (OPD) has reported industry payments to physicians since August 2013. OBJECTIVE: To evaluate the frequency, type, and value of payments received by academic neurosurgeons in the United States over a 5-yr period (2014-2018). METHODS: The OPD was queried for attending neurosurgeons from all neurosurgical training programs in the United States (n = 116). Information from the OPD was analyzed for the entire cohort as well as for comparative subgroup analyses, such as career stage, subspecialty, and geographic location. RESULTS: Of all identified neurosurgeons, 1509 (95.0%) received some payment from industry between 2014 and 2018 for a total of 106 171 payments totaling $266 407 458.33. A bimodal distribution was observed for payment number and total value: 0 to 9 (n = 438) vs > 50 (n = 563) and 0-$1000 (n = 418) vs >$10 000 (n = 653), respectively. Royalty/License was the most common type of payment overall (59.6%; $158 723 550.57). The median number (40) and value ($8958.95) of payments were highest for mid-career surgeons. The South-Central region received the most money ($117 970 036.39) while New England received the greatest number of payments (29 423). Spine surgeons had the greatest median number (60) and dollar value ($20 551.27) of payments, while pediatric neurosurgeons received the least (8; $1108.29). Male neurosurgeons received a greater number (31) and value ($6395.80) of payments than their female counterparts (11, $1643.72). CONCLUSION: From 2014 to 2018, payments to academic neurosurgeons have increased in number and value. Dollars received were dependent on geography, career stage, subspecialty and gender.
