Bromelain vs Papain Gel for Caries Removal in Primary Teeth.

AIM: The aim of the study was to evaluate and compare bromelain with papain as the chemomechanical caries removal agent in relation to their efficacy. MATERIALS AND METHODS: Thirty extracted primary molars with active carious lesion extending into dentin were selected. The samples were randomly divided into groups by sectioning the samples into two halves. Group I-cavity prepared using papain gel; group II-cavity prepared using bromelain gel. Time taken for caries removal in both the groups (I and II) was recorded with the help of a stopwatch. Following caries removal, the amount of remaining demineralized dentin was measured with the help of stereomicroscope and weld check (biological image analysis) software. RESULTS: t test is used to evaluate the significance of study parameters on continuous scale between two groups on metric parameters. The mean of residual carious dentin thickness obtained from the group II (bromelain) was 36.74 µm, which was much lower than that obtained from group I (papain) with a mean of 73.84 µm. The mean time taken in the group II (bromelain) was 335.30 seconds which was nearly equal to the mean time of group I (papain) of 352.33 seconds. CONCLUSION: The amount of remaining demineralized dentin was found to be lower in bromelain group than the papain group and time taken for the carious dentin removal was almost found similar in both bromelain and papain groups. It may be concluded that bromelain was more effective in amount of caries removal than papain. CLINICAL SIGNIFICANCE: Chemomechanical caries removal with the organic gels pose a great benefit as they are less invasive and has low side effects and cost-effective.

Nicotinamide Phosphoribosyltransferase Promotes Pulmonary Vascular Remodeling and Is a Therapeutic Target in Pulmonary Arterial Hypertension.

BACKGROUND: Pulmonary arterial hypertension is a severe and progressive disease, a hallmark of which is pulmonary vascular remodeling. Nicotinamide phosphoribosyltransferase (NAMPT) is a cytozyme that regulates intracellular nicotinamide adenine dinucleotide levels and cellular redox state, regulates histone deacetylases, promotes cell proliferation, and inhibits apoptosis. We hypothesized that NAMPT promotes pulmonary vascular remodeling and that inhibition of NAMPT could attenuate pulmonary hypertension. METHODS: Plasma, mRNA, and protein levels of NAMPT were measured in the lungs and isolated pulmonary artery endothelial cells from patients with pulmonary arterial hypertension and in the lungs of rodent models of pulmonary hypertension. Nampt+/- mice were exposed to 10% hypoxia and room air for 4 weeks, and the preventive and therapeutic effects of NAMPT inhibition were tested in the monocrotaline and Sugen hypoxia models of pulmonary hypertension. The effects of NAMPT activity on proliferation, migration, apoptosis, and calcium signaling were tested in human pulmonary artery smooth muscle cells. RESULTS: Plasma and mRNA and protein levels of NAMPT were increased in the lungs and isolated pulmonary artery endothelial cells from patients with pulmonary arterial hypertension, as well as in lungs of rodent models of pulmonary hypertension. Nampt+/- mice were protected from hypoxia-mediated pulmonary hypertension. NAMPT activity promoted human pulmonary artery smooth muscle cell proliferation via a paracrine effect. In addition, recombinant NAMPT stimulated human pulmonary artery smooth muscle cell proliferation via enhancement of store-operated calcium entry by enhancing expression of Orai2 and STIM2. Last, inhibition of NAMPT activity attenuated monocrotaline and Sugen hypoxia-induced pulmonary hypertension in rats. CONCLUSIONS: Our data provide evidence that NAMPT plays a role in pulmonary vascular remodeling and that its inhibition could be a potential therapeutic target for pulmonary arterial hypertension.

Increasing outdoor host-seeking in Anopheles gambiae over 6 years of vector control on Bioko Island.

BACKGROUND: Vector control through indoor residual spraying (IRS) has been employed on Bioko Island, Equatorial Guinea, under the Bioko Island Malaria Control Project (BIMCP) since 2004. This study analyses the change in mosquito abundance, species composition and outdoor host-seeking proportions from 2009 to 2014, after 11 years of vector control on Bioko Island. METHODS: All-night indoor and outdoor human landing catches were performed monthly in the Bioko Island villages of Mongola, Arena Blanca, Biabia and Balboa from 2009 to 2014. Collected mosquitoes were morphologically identified and a subset of Anopheles gambiae sensu lato (s.l.) were later identified molecularly to their sibling species. Mosquito collection rates, species composition and indoor/outdoor host-seeking sites were analysed using generalized linear mixed models to assess changes in mosquito abundance and behaviour. RESULTS: The overall mosquito collection rate declined in each of the four Bioko Island villages. Anopheles coluzzii and Anopheles melas comprised the An. gambiae s.l. mosquito vector population, with a range of species proportions across the four villages. The proportion of outdoor host-seeking An. gambiae s.l. mosquitoes increased significantly in all four villages with an average increase of 58.8 % [57.9, 59.64 %] in 2009 to 70.0 % [67.8, 72.0 %] in 2014. Outdoor host-seeking rates did not increase in the month after an IRS spray round compared to the month before, suggesting that insecticide repellency has little impact on host-seeking behaviour. CONCLUSION: While vector control on Bioko Island has succeeded in substantial reduction in overall vector biting rates, populations of An. coluzzii and An. melas persist. Host-seeking behaviour has changed in these An. gambiae s.l. populations, with a shift towards outdoor host-seeking. During this study period, the proportion of host-seeking An. gambiae s.l. caught outdoors observed on Bioko Island increased to high levels, exceeding 80 % in some locations. It is possible that there may be a genetic basis underlying this large shift in host-seeking behaviour, in which case outdoor feeding could pose a serious threat to current vector control programmes. Currently, the BIMCP is preparing for this potential challenge by testing source reduction as a complementary control effort that also targets outdoor transmission.

Sociodemographics Impact Competitiveness in the Neurosurgical Match: Survey Results.

BACKGROUND: The neurosurgical match involves selecting future neurosurgeons who will comprise the future national workforce, based on a competitive ranking process of applicants. We aimed to identify which sociodemographic and academic factors influence competitiveness and rank position in the match. METHODS: A Council of State Neurosurgical Societies (CSNS) survey was distributed to current U.S. neurosurgical residents. The primary outcome measure was self-reported rank position of matched program. Variables included sociodemographic and academic metrics. Fisher exact, logistic regression, and t tests were performed. RESULTS: Among the 72 respondents, median United States Medical Licensing Examination Step 1 score was 248, 34.7% were Alpha Omega Alpha inductees, 77.8% completed 1-3 sub-internship rotations, median number of publications was 5, and 13.9% had a Ph.D. Sociodemographic analysis demonstrated that 69.4% were male and 30.6% were female. Applicants with a home neurosurgery program or of female gender had statistically significantly higher odds of matching into a top 3 program on their rank list (odds ratio = 9 and odds ratio = 6, respectively). Female applicants exhibited similar mean, but less variance, compared with male respondents for United States Medical Licensing Examination Step 1 scores and number of publications. Respondents with a top 3 program match were more likely to agree that the home program supported their pursuance of neurosurgery. CONCLUSIONS: Two sociodemographic factors were independently associated with high match rank: presence of home neurosurgery program and female gender. Female respondents reported consistently strong academic metrics (similar mean, but less variance, compared with male respondents).

Functional Outcomes of Primary Hemiarthroplasty for Unstable Intertrochanteric Fractures in the Elderly: A Prospective Observational Study.

Background and objective Intertrochanteric fractures pose a growing healthcare challenge among the elderly, demanding effective management strategies. This study addressed the rising incidence of hip fractures, emphasizing the complications associated with traditional nonsurgical approaches. It aimed to explore postoperative functional outcomes and complications associated with primary hemiarthroplasty as an alternative to internal fixation for unstable intertrochanteric fractures in the elderly. Materials and methods This study included 20 elderly patients undergoing hemiarthroplasty for unstable intertrochanteric fractures. It evaluated key variables such as patient demographics, comorbidities, fracture characteristics, surgical approach, and postoperative metrics. To perform hemiarthroplasty, we utilized a nonmodular bipolar prosthesis with cement. Postoperative follow-up included an assessment of clinical and radiological parameters, focusing on outcomes and complications. Results The mean age of the participants was 71.65 years; it was found that a significant segment of the participants (n=9, 45%) did not have any comorbidities. The surgical outcomes were characterized by minimal blood loss (275 ± 57.35 ml), short hospital stays (6.55± 1.95 days), and satisfactory operative durations (80.25 ± 10.19 minutes). Additionally, 14 (70%) patients did not require blood transfusions. After the surgery, complications were minimal, and there were no cases of deep wound complications, prosthesis dislocations, or deep vein thrombosis. The Harris Hip Scores reflected favorable outcomes in 14 cases (72.7%), with good or excellent hip scores. Conclusions Our findings revealed that primary hemiarthroplasty is a reliable and effective strategy for managing unstable intertrochanteric fractures in the elderly, providing stable joints and acceptable complication rates. Early mobilization, facilitated by hemiarthroplasty, mitigates postoperative complications, making it a viable alternative for elderly patients.

A Systematic Review of the State of Neurosurgical Disparities Research: Past, Present, and Future.

BACKGROUND: The social determinants of health, which influence healthcare access, patient outcomes, and population-level burden of disease, contribute to health disparities experienced by marginalized patient populations. In the present study, we sought to evaluate the landscape of health disparities research within neurosurgery. METHODS: Embase, Ovid-MEDLINE, Scopus, Web of Science, Cochrane Library, and ProQuest Dissertations databases were queried for original research on health disparities regarding access to, outcomes of, and/or postoperative management after neurosurgical procedures in the United States. RESULTS: Of 883 studies screened, 196 were included, of which 144 had a neurosurgery-affiliated author. We found a significant increase in the number of neurosurgical disparities reports beginning in 2010, with only 10 studies reported before 2010. Of the included studies, 3.1% used prospective methods and 63.8% used data from national registries. The disparities analyzed were racial/ethnic (79.6%), economic/socioeconomic (53.6%), gender (18.9%), and disabled populations (0.5%), with 40.1% analyzing multiple or intersecting disparities. Of the included reports, 96.9% were in phase 1 (detecting phase of disparities research), with a few studies in phase 2 (understanding phase), and none in phase 3 (reducing phase). The spine was the most prevalent subspecialty evaluated (34.2%), followed by neuro-oncology (19.9%), cerebrovascular (16.3%), pediatrics (10.7%), functional (9.2%), general neurosurgery (5.1%), and trauma (4.1%). Senior authors with a neurosurgical affiliation accounted for 79.2% of the reports, 93% of whom were academically affiliated. CONCLUSIONS: Although a recent increase has occurred in neurosurgical disparities research within the past decade, most studies were limited to the detection of disparities without understanding or evaluating any interventions for a reduction in disparities. Future research in neurosurgical disparities should incorporate the latter 2 factors to reduce disparities and improve outcomes for all patients.

Objective evaluation of cervical vertebral bone age' its reliability in comparison with hand-wrist bone age: by TW3 method.

AIM: The aim of this study was to establish the validity of a new method for evaluating skeletal maturation by assessing the 3rd and 4th cervical vertebrae seen in the cephalometric radiograph. MATERIALS AND METHODS: This study consisted of a sample of 50 patients in the age group of 8 to 14 years of age. Chronologically, they were divided into six groups, based on the age consisting of a minimum of six to a maximum of 10 subjects. All the patients included in the study were females. The selected subjects were clinically examined and then age and date of birth of the patient in years and months was noted. Then lateral cephalograms and hand-wrist radiographs of the patient were taken on the same day with good clarity and contrast. RESULTS: The results suggested that cervical vertebral bone age on cephalometric radiographs calculated with this method is as reliable at estimating bone age as is the Tanner-Whitehouse 3 (TW3) method on hand-wrist radiographs. By determining the cervical vertebral bone age, skeletal maturity can be evaluated in a detailed and objective manner with cephalometric radiographs. CONCLUSION: The ability to accurately appraise skeletal maturity from cervical vertebral maturation, without the need for additional radiographs, has the potential to improve orthodontic diagnostic and therapeutic decisions. The technique's simplicity and ease of use should encourage this method as a frst level diagnostic tool to assess skeletal maturation. Clinical signifcance: This study revealed that the timing and sequence of ossifcation of the bones in hand and wrist and cervical vertebrae were able to relate the skeletal development of the various skeletal maturity indicators to a child's development. This method provided a mean with which one can determine the skeletal maturity of a person and thereby determine whether the possibility of potential growth existed.

Effect of tongue cleaning methods and oral mutans streptococci level.

INTRODUCTION: Tongue scraping and brushing have been appreciated for hundreds of years but are still appreciated or used by the public. Scientific evidence has validated the need to practice habitual and tongue cleaning as part of daily home oral hygiene procedures. OBJECTIVE: To assess and compare the effect of tongue scraping and tongue brushing on oral Mutans streptococci level. MATERIALS AND METHODS: A total of 20 healthy subjects aged 14 to 15 years were randomly selected. Flat plastic tongue scraper and Nylon multitufted small headed toothbrush are the two tongue cleaning devise used. Unstimulated salivary samples were obtained at 4 intervals from each individual. Salivary samples were inoculated on Mitis Salivary Agar Plate and Sorbital Broth was used for identification of Mutans streptococci group. RESULTS: Paired and unpaired 't' test were employed. Reduiction in the Mutans streptococci level from 48.4 × 10(4) CFU and 38.3 × 10(4) CFU at baseline in tongue scraping and tongue brushing group respectively to 0.34 × 10(4) and 0.39 × 104 CFU after 7th day. CONCLUSION: Both tongue coating removal methods evaluated were efficient in reducing mutans streptococci level. This implies that physical removal of the coating on the dorsum of the tongue is important and not the method used for the same.

Current Trends in Subspecialty Fellowship Training for 1691 Academic Neurological Surgeons.

OBJECTIVE: Neurosurgical subspecialty fellowship training has become increasingly popular in recent decades. However, few studies have evaluated recent trends in postgraduate subspecialty education. This study aims to provide a detailed cross-sectional analysis of subspecialty fellowship training completion trends and demographics among U.S. academic neurosurgeons. METHODS: Academic clinical faculty (M.D. or D.O.) teaching at accredited neurosurgery programs were included. Demographic, career, and fellowship data were collected from departmental physician profiles and the American Association of Neurological Surgeons (AANS) membership database. Relative citation ratio scores were retrieved using the National Institutes of Health iCite tool. RESULTS: This study included 1691 surgeons (1756 fellowships) from 125 institutions. The majority (79.13%) reported fellowship training. Fellowship completion was more common among recent graduates (residency year >2000), as was training in multiple subspecialties (P < 0.0001). Spine was the most popular subspecialty (16.04%), followed by pediatrics (11.18%), and cerebrovascular (9.46%). The least common were trauma/critical care (2.52%) and peripheral nerve (1.26%). Spine, neuroradiology, and endovascular subspecialties grew in popularity over time. Pediatrics and spine were the most popular for females and males, respectively. Epilepsy and cerebrovascular had the most full professors, while endovascular and spine had the most assistant professors. Stereotactic/functional and epilepsy had the most Ph.Ds. Fellowship training correlated with higher weighted, but not mean, relative citation ratio scores among associate (P = 0.002) and full professors (P = 0.005). CONCLUSIONS: There is an emerging proclivity for additional fellowship training among young neurosurgeons, often in multiple subspecialties. These findings are intended to help guide professional decision-making and optimize the delivery of postgraduate education.

Pupillary light reflex measured with quantitative pupillometry has low sensitivity and high specificity for predicting neuroworsening after traumatic brain injury.

BACKGROUND: Triage and neurological assessment of the 1.7 million traumatic brain injuries occurring annually is often done by nurse practitioners and physician assistants in the emergency department. Subjective assessments, such as the neurological examination that includes evaluation of the pupillary light reflex (PLR), can contain bias. Quantitative pupillometry (QP) standardizes and objectifies the PLR examination. Additional data are needed to determine whether QP can predict neurological changes in a traumatic brain injury (TBI) patient. PURPOSE: This study examines the effectiveness of QP in predicting neurological decline within 24 hours of admission following acute TBI. METHODOLOGY: This prospective, observational, clinical trial used pragmatic sampling to assess PLR in TBI patients using QP within 24 hours of ED admission. Chi-square analysis was used to determine change in patient status, through Glasgow Coma Scale (GCS), at baseline and within 24 hours of admission, to the QP. RESULTS: There were 95 participants included in the analysis; of whom 35 experienced neuroworsening, defined by change in GCS of >2 within the first 24 hours of admission. There was a significant association between an abnormal Neurological Pupil index (NPi), defined as NPi of <3, and neuroworsening (p < .0001). The sensitivity (51.43%) and specificity (91.67%) of abnormal NPi in predicting neuroworsening were varied. CONCLUSION: There is a strong association between abnormal NPi and neuroworsening in the sample of TBI patients with high specificity and moderate sensitivity. IMPLICATIONS: NPi may be an early indicator of neurological changes within 24 hours of ED admission in patients with TBI.

Back to basal: contemporary cerebrovascular cohort study of the supratentorial-infraoccipital approach.

OBJECTIVE: The objective of this paper was to assess applications of the supratentorial-infraoccipital (STIO) approach for cerebrovascular neurosurgery. METHODS: The authors conducted a cohort study of all consecutive cases in which the STIO approach was used during the study period, December 1995 to January 2021, as well as a systematic review of the literature. RESULTS: Twenty-five cerebrovascular cases were identified in which the STIO approach was used. Diagnoses included arteriovenous malformation (n = 15), cerebral cavernous malformation (n = 5), arteriovenous fistula (n = 4), and aneurysm (n = 1). The arteriovenous malformations consisted of Spetzler-Martin grade II (n = 3), grade III (n = 8), and grade IV (n = 4) lesions. Lesion locations included the occipital lobe (n = 15), followed by the tentorial dural (n = 4), temporal-occipital (n = 3), temporal (n = 1), thalamic (n = 1), and quadrigeminal cistern (n = 1) regions. Many patients (75%) experienced transient visual deficits attributable to retraction of the occipital lobe, all of which resolved. As of last follow-up (n = 12), modified Rankin Scale scores had improved for 6 patients and were unchanged for 6 patients compared with the preoperative baseline. CONCLUSIONS: The STIO approach is a safe and effective skull base approach that provides a specialized access corridor for appropriately selected cerebrovascular lesions.

Light traps fail to estimate reliable malaria mosquito biting rates on Bioko Island, Equatorial Guinea.

BACKGROUND: The human biting rate (HBR), an important parameter for assessing malaria transmission and evaluating vector control interventions, is commonly estimated by human landing collections (HLC). Although intense efforts have been made to find alternative non-exposure mosquito collection methods, HLC remains the standard for providing reliable and consistent HBRs. The aim of this study was to assess the relationship between human landing and light trap collections (LTC), in an attempt to estimate operationally feasible conversion factors between the two. The study was conducted as part of the operational research component of the Bioko Island Malaria Control Project (BIMCP), Equatorial Guinea. METHODS: Malaria mosquitoes were collected indoors and outdoors by HLCs and LTCs in three villages on Bioko Island, Equatorial Guinea during five bimonthly collections in 2009. Indoor light traps were suspended adjacent to occupied long-lasting, insecticide-treated bed nets. Outdoor light traps were placed close to the outer wall under the roof of the collection house. Collected specimens were subjected to DNA extraction and diagnostic PCR to identify species within the Anopheles gambiae complex. Data were analysed by simple regression of log-transformed values and by Bayesian regression analysis. RESULTS: There was a poor correlation between the two collection methods. Results varied by location, venue, month, house, but also by the statistical method used. The more robust Bayesian analyses indicated non-linear relationships and relative sampling efficiencies being density dependent for the indoor collections, implying that straight-forward and simple conversion factors could not be calculated for any of the locations. Outdoor LTC:HLC relationships were weak, but could be estimated at 0.10 and 0.07 for each of two locations. CONCLUSIONS: Light trap collections in combination with bed nets are not recommended as a reliable method to assess human biting rates on Bioko Island. Different statistical analyses methods give variable and inconsistent results. Substantial variation in collection methods prevents the determination of reliable and operationally feasible conversion factors for both indoor and outdoor data. Until improved mosquito collection methods are developed that can provide reliable and unbiased HBR estimates, HLCs should continue to serve as the reference method for HBR estimation.

Limited usefulness of microsatellite markers from the malaria vector Anopheles gambiae when applied to the closely related species Anopheles melas.

Anopheles melas is a brackish water mosquito found in coastal West Africa where it is a dominant malaria vector locally. In order to facilitate genetic studies of this species, 45 microsatellite loci originally developed for Anopheles gambiae were sequenced in An. melas. Those that were suitable based on repeat number and flanking regions were examined in 2 natural populations from Equatorial Guinea. Only 15 loci were eventually deemed suitable as polymorphic markers in An. melas populations. These loci were screened in 4 populations from a wider geographic range. Heterozygosity estimates ranged from 0.18 to 0.79, and 2.5-15 average alleles were observed per locus, yielding 13 highly polymorphic markers and 2 loci with lower variability. To examine the usefulness of microsatellite markers when applied in a sibling species, the original An. gambiae specific markers were used to amplify 5 loci in An. melas. Null alleles were found for 1 An. gambiae marker. We discuss the pitfalls of using microsatellite loci across closely related species and conclude that in addition to the problem of null alleles associated with this practice, many loci may prove to be of very limited use as polymorphic markers even when used in a sibling species.

Evolution of Intracranial-Intracranial Bypass Surgery: A Bibliometric Analysis.

OBJECTIVE: Modern cerebrovascular bypass surgery uses either extracranial-intracranial (EC-IC) or intracranial-intracranial (IC-IC) approaches. Compared with EC-IC bypasses, IC-IC bypasses allow neurosurgeons to safely address tumors, aneurysms, and other lesions using shorter grafts that are well matched to the size of recipient vessels. Fewer than 100 articles have been published on IC-IC bypasses compared with more than 1000 on EC-IC bypasses. This study examined the increase of interest and innovation in IC-IC bypass. METHODS: PubMed and Web of Science were searched using keywords specific to IC-IC bypass, yielding 717 articles supplemented with 36 reports from other databases and gray literature. The articles were reviewed, and 98 articles were selected for further evaluation. Final articles were categorized as innovations or retrospective studies. Publication metrics were passed through an analytic program to assess statistical measures of growth. RESULTS: The number of publications describing innovations (n = 52) and retrospective studies (n = 46) in IC-IC surgical techniques increased exponentially (R2 = 0.983 and R2 = 0.993, respectively), with both interest and research in the field increasing. The rate of publications in each group also increased. In recent years, increasing numbers of global institutions have researched and published on IC-IC bypasses. CONCLUSIONS: As more work is undertaken on IC-IC bypasses, it is critical for knowledge to be shared through research, collaboration, publication, and early teaching within residency training programs. This field has increased exponentially in the past 2 decades and has yet to reach an inflection point, indicating possible additional interest and growth over time.

Bibliometric Analysis of the Extracranial-Intracranial Bypass Literature.

OBJECTIVE: Extracranial-intracranial (EC-IC) bypass is a procedure in which a blood vessel outside the skull is connected to one inside the skull to improve cerebral blood flow. Certain aneurysms cannot be treated through standard clipping, and EC-IC bypass may be recommended in such cases. A vast body of literature exists on the use of EC-IC bypass as a treatment for cerebrovascular disorders. While beneficial to surgeons, these publications may not reach all the intended audience, which encourages the use of bibliometric analyses. Although a fraction of historically meaningful publications may not have been sufficiently valued through citation count, bibliometric analysis is the gold standard for assessing the impact of a publication. METHODS: Using bibliometric analysis, we queried the Web of Science database to identify the 50 most impactful publications on EC-IC bypass based on citation count. RESULTS: The literature search retrieved 125 publications that met inclusion criteria, from which the top 50 most-cited ones were selected. The mean number of citations for each article was 117.06 (range 35-1437). Case reports and series constituted 15 (30%) of the top 50 publications on EC-IC bypass, followed by 8 (16%) editorials and 7 (14%) randomized controlled trials. A total of 265 authors in 10 countries contributed to the 50 manuscripts, which were published in 15 different journals. CONCLUSIONS: We retrieved the top 50 most-cited articles on EC-IC bypass surgery and identified the landmark publications to provide a foundational understanding of the procedure as a treatment for complex disorders.

Political Campaign Contributions of Surgeons in the United States Throughout the 2020 Election Cycle.

Importance: Political engagement by the physician workforce is necessary to ensure continued representation of their interests in health care legislation. Limited data are available pertaining to the political involvement of US surgeons. Objective: To analyze the magnitude and distribution of political donations made by all US surgeons throughout the 2020 election cycle. Design, Setting, and Participants: Partisan and geographical differences in surgeon contributions by aggregating data (January 1 through December 31, 2020) from the US Federal Election Commission database were analyzed. Contributions were labeled as Republican, Democrat, or independent depending on the committee they were designated to. Main Outcomes and Measures: Differences in contributions to Republicans, Democrats, and independent candidates for all US surgeons and for subgroups. Results: For the 2020 election year, a total of 53 944 donations were made by surgeons in the United States, amounting to $9 223 350.68. Among all surgical specialties, the top 5 highest number of contributions were made from orthopedic surgeons (n = 15 081), ophthalmic surgeons (n = 14 836), neurological surgeons (n = 7481), urologists (n = 4544), and plastic surgeons (n = 4060). Of these donations, 59.46% (n = 32 107) were made to the Republican party ($5 420 326), 30.83% (n = 16 644) were made to the Democratic party ($1 612 775), and 9.71% (n = 5243) were made to nonpartisan (ie, independent) organizations ($2 190 250). Overall, pediatric surgeons reported the lowest mean contribution amount of $59.43, whereas thoracic surgeons reported the highest mean contribution amount of $225.19. Conclusions and Relevance: Health care legislation has an immense impact on how medicine is practiced and utilized. This analysis reveals a high degree of political activity of surgeons across different specialties and geographic regions.

Patient satisfaction reviews for 967 spine neurosurgeons on Healthgrades.

OBJECTIVE: Patients are increasingly relying on independent physician rating websites (PRWs) to obtain information about healthcare providers. Healthgrades.com is a widely used PRW that allows patients to rate physicians on various metrics of performance and quality of care. This study categorically investigated the correlations between demographics of spine neurosurgeons and online ratings on Healthgrades to better understand the factors driving patient satisfaction in spine surgery in the United States. METHODS: In August-December 2019, the authors performed a retrospective data analysis using Healthgrades. The American Association of Neurological Surgeons (AANS) membership database was used to identify spine neurosurgeons in the United States and extract biographical and career data. Individuals with an academic practice were further investigated for academic rank, leadership, and fellowship training. Scores from eight patient satisfaction metrics (PSMs) were collected for each surgeon from Healthgrades. RESULTS: A total of 967 spine neurosurgeons were included in the study cohort. Patient satisfaction did not correlate with sex, PhD acquisition, academic status, or academic rank. Among those who were academic surgeons, completion of fellowship training was associated with higher ratings. Geographical location of practice did not influence patient satisfaction. Prolonged wait time was an independent predictor of decreased patient satisfaction and was a key confounding variable underlying trends seen with advanced career duration and age. CONCLUSIONS: Overall, patients rated spine neurosurgeons highly favorably on the Healthgrades website. Due to the emerging role of PRWs in locating and assessing providers, it is important for both patients and clinicians to understand the factors that impact patient experience.

Optimizing the residency application process: insights from neurological surgery during the pandemic virtual application cycle.

OBJECTIVE: In this article, the authors describe the impact of the COVID-19 virtual match cycle and discuss approaches to optimize future cycles through applicant and neurosurgical education leadership insights. METHODS: Anonymous surveys of neurosurgery program leaders (program directors and program chairs), program administrators (PAs), and 2020-2021 neurosurgery residency match applicants were distributed by the SNS, in conjunction with the Association of Resident Administrators in Neurological Surgery and AANS Young Neurosurgeons Committee. RESULTS: Responses were received from 77 (67.0%) of 115 PAs, 119 (51.7%) of 230 program leaders, and 124 (44.3%) of 280 applicants representing geographically diverse regions. During the virtual application cycle relative to the previous year, programs received more Electronic Residency Application Service applications (mean 314.8 vs 285.3, p < 0.0001) and conducted more applicant interviews (mean 45.2 vs 39.9, p = 0.0003). More than 50% of applicants applied to > 80 programs; 60.3% received ≤ 20 interview invitations, and 9% received > 40 invitations. Overall, 65% of applicants completed ≤ 20 interviews, whereas 34.7% completed > 20 interviews. Program leaders described one 4-week home subinternship (93.3%) and two 4-week external subinternships (68.9%) as optimal neurosurgical exposure; 62.8% of program leaders found the standardized letter of recommendation template to be somewhat (47.5%) or significantly (15.3%) helpful. Applicants, PAs, and program leaders all strongly preferred a hybrid model of in-person and virtual interview options for future application cycles over all in-person or all virtual options. Ninety-three percent of applicants reported matching within their top 10-ranked programs, and 52.9% of programs matched residents within the same decile ranking as in previous years. CONCLUSIONS: Optimizing a national strategy for the neurosurgery application process that prioritizes equity and reduces costs, while ensuring adequate exposure for applicants to gain educational opportunities and evaluate programs, is critical to maintain a successful training system.

Trends in Matriculation from Neurological Surgery Training Programs into Academic Versus Private Practice.

OBJECTIVE: A career in academic neurosurgery is an arduous endeavor. Specific factors influencing physician practice preferences remain unclear. This study analyzes data from the American Association of Neurological Surgeons membership identifying the impact of several demographic and educational characteristics influencing neurosurgical career choices centered on academia, private practice, or a combination in the United States. METHODS: A list of all current neurosurgeons was obtained from the American Association of Neurological Surgeons membership, and information on physician characteristics was collected via internet searches and institutional databases. The practice type of all neurosurgeons considered in this study were categorized as follows: private practice, academic, or a combination of private practice and academic, termed privademic. These data were subsequently correlated to race, gender, current age, training at a top 40 National Institutes of Health-funded medical school or residency program, and current practice. RESULTS: The median age of private practice and academic neurosurgeons was 58.18 and 53.61 years, respectively (P < 0.001). Age was significantly associated with practicing in an academic setting (odds ratio 0.96), with younger neurosurgeons pursuing careers in academia. Data indicated a positive and statistically significant contribution of female gender (P < 0.001) and training at a top-40 National Institutes of Health-funded institution to practicing in an academic setting (P < 0.01). CONCLUSIONS: Neurosurgery as a field has grown significantly over the past century. The authors recommend that future efforts seek to diversify the neurosurgical workforce by considering practice setting, demographic characteristics, and educational background.
