Disparities in Access to Deep Brain Stimulation for Parkinson's Disease and Proposed Interventions: A Literature Review.

BACKGROUND: Deep brain stimulation (DBS) is an effective therapy for Parkinson's disease (PD), but disparities exist in access to DBS along gender, racial, and socioeconomic lines. SUMMARY: Women are underrepresented in clinical trials and less likely to undergo DBS compared to their male counterparts. Racial and ethnic minorities are also less likely to undergo DBS procedures, even when controlling for disease severity and other demographic factors. These disparities can have significant impacts on patients' access to care, quality of life, and ability to manage their debilitating movement disorders. KEY MESSAGES: Addressing these disparities requires increasing patient awareness and education, minimizing barriers to equitable access, and implementing diversity and inclusion initiatives within the healthcare system. In this systematic review, we first review literature discussing gender, racial, and socioeconomic disparities in DBS access and then propose several patient, provider, community, and national-level interventions to improve DBS access for all populations.

Global Economic Evaluation of the Reported Costs of Deep Brain Stimulation.

INTRODUCTION: Despite the known benefits of deep brain stimulation (DBS), the cost of the procedure can limit access and can vary widely. Our aim was to conduct a systematic review of the reported costs associated with DBS, as well as the variability in reporting cost-associated factors to ultimately increase patient access to this therapy. METHODS: A systematic review of the literature for cost of DBS treatment was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed and Embase databases were queried. Olsen & Associates (OANDA) was used to convert all reported rates to USD. Cost was corrected for inflation using the US Bureau of Labor Statistics Inflation Calculator, correcting to April 2022. RESULTS: Twenty-six articles on the cost of DBS surgery from 2001 to 2021 were included. The median number of patients across studies was 193, the mean reported age was 60.5 ± 5.6 years, and median female prevalence was 38.9%. The inflation- and currency-adjusted mean cost of the DBS device was USD 21,496.07 ± USD 8,944.16, the cost of surgery alone was USD 14,685.22 ± USD 8,479.66, the total cost of surgery was USD 40,942.85 ± USD 17,987.43, and the total cost of treatment until 1 year of follow-up was USD 47,632.27 ± USD 23,067.08. There were no differences in costs observed across surgical indication or country. CONCLUSION: Our report describes the large variation in DBS costs and the manner of reporting costs. The current lack of standardization impedes productive discourse as comparisons are hindered by both geographic and chronological variations. Emphasis should be put on standardized reporting and analysis of reimbursement costs to better assess the variability of DBS-associated costs in order to make this procedure more cost-effective and address areas for improvement to increase patient access to DBS.

Cost considerations for vestibular schwannoma screening and imaging: a systematic review.

Vestibular schwannomas (VS) account for approximately 8% of all intracranial neoplasms. Importantly, the cost of the diagnostic workup for VS, including the screening modalities most commonly used, has not been thoroughly investigated. Our aim is to conduct a systematic review of the published literature on costs associated with VS screening. A systematic review of the literature for cost of VS treatment was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The terms "vestibular schwannoma," "acoustic neuroma," and "cost" were queried using the PubMed and Embase databases. Studies from all countries were considered. Cost was then corrected for inflation using the US Bureau of Labor Statistics Inflation Calculator, correcting to April 2022. The search resulted in an initial review of 483 articles, of which 12 articles were included in the final analysis. Screening criteria were used for non-neurofibromatosis type I and II patients who complained of asymmetric hearing loss, tinnitus, or vertigo. Patients included in the studies ranged from 72 to 1249. The currency and inflation-adjusted mean cost was $418.40 (range, $21.81 to $487.03, n = 5) for auditory brainstem reflex and $1433.87 (range, $511.64 to $1762.15, n = 3) for non-contrasted computed tomography. A contrasted magnetic resonance imaging (MRI) scan was found to have a median cost of $913.27 (range, $172.25-$2733.99; n = 8) whereas a non-contrasted MRI was found to have a median cost of $478.62 (range, $116.61-$3256.38, n = 4). In terms of cost reporting, of the 12 articles, 1 (8.3%) of them separated out the cost elements, and 10 (83%) of them used local prices, which include institutional costs and/or average costs of multiple institutions. Our findings describe the limited data on published costs for screening and imaging of VS. The paucity of data and significant variability of costs between studies indicates that this endpoint is relatively unexplored, and the cost of screening is poorly understood.

Complications associated with combined direct and indirect bypass in Moyamoya Disease: A meta-analysis.

Bypass revascularization helps prevent complications in Moyamoya Disease (MMD). To systematically review complications associated with combined direct and indirect (CB) bypass in MMD and analyze differences between the adult and pediatric populations. A systematic literature review was conducted per PRISMA guidelines. PUBMED, Cochrane Library, Web of Science, and CINAHL, were queried from January 1980 to March 2022. Complications were defined as any event in the immediate post-surgical period of a minimum 3 months follow-up. Exclusion criteria included lack of surgical complication reports, non-English articles, and CB unspecified or reported separately. 18 final studies were included of 1580 procured. 1151 patients (per study range = 10-150, mean = 63.9) were analyzed. 9 (50.0%) studies included pediatric patients. There were 32 total hemorrhagic, 74 total ischemic and 16 total seizure complications, resulting in a rate of 0.04 (95% CI 0.03, 0.06), 0.7 (95% CI 0.04, 0.10) and 0.03 (95% CI 0.02, 0.05), respectively. The rate of hemorrhagic complications in the pediatric showed no significant difference from the adult subgroup (0.03 (95% CI 0.01-0.08) vs. 0.06 (95% CI 0.04-0.10, p = 0.19), such as the rate of ischemic complications (0.12 (95% CI 0.07-0.23) vs. 0.09 (95% CI 0.05-0.14, p = 0.40). Ischemia is the most common complication in CB for MMD. Pediatric patients had similar hemorrhagic and ischemic complication rates compared to adults.

Enhancing the quality of evidence, comparability, and reproducibility in brain arteriovenous malformations treated with open surgery research: a systematic review and proposal of a reporting guideline for surgical and clinical outcomes.

Brain Arteriovenous Malformations (bAVMs) are rare but high-risk developmental anomalies of the vascular system. Microsurgery through craniotomy is believed to be the mainstay standard treatment for many grades of bAVMs. However, a significant challenge emerges in the existing body of clinical studies on open surgery for bAVMs: the lack of reproducibility and comparability. This study aims to assess the quality of studies reporting clinical and surgical outcomes for bAVMs treated by open surgery and develop a reporting guideline checklist focusing on essential elements to ensure comparability and reproducibility. This is a systematic literature review that followed the PRISMA guidelines with the search in Medline, Embase, and Web of Science databases, for studies published between January 1, 2018, and December 1, 2023. Included studies were scrutinized focusing on seven domains: (1) Assessment of How Studies Reported on the Baseline Characteristics of the Patient Sample; (2) Assessment and reporting on bAVMs grading, anatomical characteristics, and radiological aspects; (3) Angioarchitecture Assessment and Reporting; (4) Reporting on Pivotal Concepts Definitions; (5) Reporting on Neurosurgeon(s) and Staff Characteristics; (6) Reporting on Surgical Details; (7) Assessing and Reporting Clinical and Surgical Outcomes and AEs. A total of 47 studies comprising 5,884 patients were included. The scrutiny of the studies identified that the current literature in bAVM open surgery is deficient in many aspects, ranging from fundamental pieces of information of methodology to baseline characteristics of included patients and data reporting. Included studies demonstrated a lack of reproducibility that hinders building cumulative evidence. A bAVM Open Surgery Reporting Guideline with 65 items distributed across eight domains was developed and is proposed in this study aiming to address these shortcomings. This systematic review identified that the available literature regarding microsurgery for bAVM treatment, particularly in studies reporting clinical and surgical outcomes, lacks rigorous scientific methodology and quality in reporting. The proposed bAVM Open Surgery Reporting Guideline covers all essential aspects and is a potential solution to address these shortcomings and increase transparency, comparability, and reproducibility in this scenario. This proposal aims to advance the level of evidence and enhance knowledge regarding the Open Surgery treatment for bAVMs.

Post-mastectomy Breast Reconstruction With Gas vs Saline Tissue Expanders: Does the Fill Type Matter?

The most common reconstruction technique following mastectomy is a 2-stage technique that involves tissue expansion followed by definitive implant-based reconstruction (IBR). Tissue expanders (TEs) have classically used saline for initial fill; however, TEs with an initial gas fill (GTE)-including the CO2-based AeroForm (AirXpanders, San Francisco, CA) TE and TEs initially filled with atmospheric air-have been increasingly used in the past decade. We aimed to compare the outcomes in breast reconstruction for tissue expanders initially filled with saline vs gas. PubMed was queried for studies comparing gas- and saline-filled tissue expanders (STEs) used in IBR. A meta-analysis was performed on major postoperative outcomes and the required expansion and definitive reconstruction time. Eleven studies were selected and included in the analysis. No significant differences existed between tissue expansion with GTEs vs STEs for 11 of the 13 postoperative outcomes investigated. Out of the complications investigated, only the risk of infection/cellulitis/abscess formation was significantly lower in the GTE cohort (odds ratio 0.62; 95% CI, 0.47 to 0.82; P = .0009). The time to definitive reconstruction was also significantly lower in the GTE cohort (mean difference [MD], 45.85 days; 95% CI, -57.80 to -33.90; P < .00001). The total time to full expansion approached significance in the GTE cohort (MD, -20.33 days; 95% CI, -41.71 to 1.04; P = .06). A cost analysis considering TE cost and infection risk determined that GTE use saved a predicted $2055.34 in overall healthcare costs. Surgical outcomes for both fill types were predominantly similar; however, GTEs were associated with a significantly decreased risk of postoperative infection compared to saline-filled TEs. GTEs could also reduce healthcare expenditures and require less time until definitive reconstruction after placement.

Social Determinants of Health in Imaging-based Cancer Screening: A Case-based Primer with Strategies for Care Improvement.

Health disparities, preventable differences in the burden of disease and disease outcomes often experienced by socially disadvantaged populations, can be found in nearly all areas of radiology, including emergency radiology, neuroradiology, nuclear medicine, image-guided interventions, and imaging-based cancer screening. Disparities in imaging-based cancer screening are especially noteworthy given the far-reaching population health impact. The social determinants of health (SDoH) play an important role in disparities in cancer screening and outcomes. Through improved understanding of how SDoH can drive differences in health outcomes in radiology, radiologists can effectively provide patient-centered, high-quality, and equitable care. Radiologists and radiology practices can become active partners in efforts to assist patients along their imaging journey and overcome existing barriers to equitable cancer screening care for traditionally marginalized populations. As radiology exists at the intersection of diagnostic imaging, image-guided diagnostic intervention, and image-guided treatment, radiologists are uniquely positioned to design these strategies. Cost-effective and socially conscious strategies that address barriers to equitable care can improve both public health and equitable health outcomes. Potential strategies include championing supportive health policy, reducing out-of-pocket costs, increasing price transparency, improving education and outreach efforts, ensuring that appropriate language translation services are available, providing individualized assistance with appointment scheduling, and offering transportation assistance and childcare. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Persistent autism-relevant behavioral phenotype and social neuropeptide alterations in female mice offspring induced by maternal transfer of PBDE congeners in the commercial mixture DE-71.

Polybrominated diphenyl ethers (PBDEs) are ubiquitous persistent organic pollutants (POPs) that are known neuroendocrine disrupting chemicals with adverse neurodevelopmental effects. PBDEs may act as risk factors for autism spectrum disorders (ASD), characterized by abnormal psychosocial functioning, although direct evidence is currently lacking. Using a translational exposure model, we tested the hypothesis that maternal transfer of a commercial mixture of PBDEs, DE-71, produces ASD-relevant behavioral and neurochemical deficits in female offspring. C57Bl6/N mouse dams (F0) were exposed to DE-71 via oral administration of 0 (VEH/CON), 0.1 (L-DE-71) or 0.4 (H-DE-71) mg/kg bw/d from 3 wk prior to gestation through end of lactation. Mass spectrometry analysis indicated in utero and lactational transfer of PBDEs (in ppb) to F1 female offspring brain tissue at postnatal day (PND) 15 which was reduced by PND 110. Neurobehavioral testing of social novelty preference (SNP) and social recognition memory (SRM) revealed that adult L-DE-71 F1 offspring display deficient short- and long-term SRM, in the absence of reduced sociability, and increased repetitive behavior. These effects were concomitant with reduced olfactory discrimination of social odors. Additionally, L-DE-71 exposure also altered short-term novel object recognition memory but not anxiety or depressive-like behavior. Moreover, F1 L-DE-71 displayed downregulated mRNA transcripts for oxytocin (Oxt) in the bed nucleus of the stria terminalis (BNST) and supraoptic nucleus, and vasopressin (Avp) in the BNST and upregulated Avp1ar in BNST, and Oxtr in the paraventricular nucleus. Our work demonstrates that developmental PBDE exposure produces ASD-relevant neurochemical, olfactory processing and behavioral phenotypes that may result from early neurodevelopmental reprogramming within central social and memory networks.

Does recovery after sport-related concussion vary by time point in a season? A multi-sport investigation.

OBJECTIVE: Seasonality, or the specific point in time within a season in which the injury occurs, may have an impact on the recovery following sport-related concussions (SRCs). In a cohort of high school athletes across multiple sports, the authors sought to investigate the impact of seasonality on 1) concussion frequency, 2) acute symptom presentation (initial Post-Concussion Symptom Scale [PCSS] score), and 3) recovery outcomes, including the time to return to learn (RTL), symptom resolution (SR), and return to play (RTP). METHODS: A retrospective, single-institution, cohort study was conducted with adolescent athletes aged 14-19 years who sustained an SRC between November 2017 and April 2022 and presented to a multidisciplinary specialty concussion clinic. The time from first practice to the end of the regular season was evenly trichotomized into early, middle, and late season. Teams that participated in the playoffs were included in a subanalysis. One-way ANOVA and independent t-tests were used to compare PCSS scores, RTL, SR, and RTP across seasonality. Univariable and multivariable regressions were used to determine predictors for recovery, defined as total days from initial visit to each outcome. RESULTS: Of the 1504 eligible athletes, 620 high school athletes met inclusion criteria; 491 (79.2%) sustained a concussion during the regular season with 73 (14.9%), 136 (27.7%), and 282 (57.4%) concussions occurring in the early, middle, and late seasons, respectively. No differences were seen for initial PCSS score, RTL, SR, or RTP across early-, middle-, and late-season concussions. The initial PCSS score was significantly higher for playoff compared with regular-season concussions (playoffs: 33.4 ± 27.5; regular season: 23.3 ± 22.8; t = -1.979, p = 0.048). A subanalysis of playoff concussions (n = 24) compared with regular-season concussions showed that concussion in the playoffs was associated with a higher initial PCSS score in univariable (ß = 0.093, p = 0.048) and multivariable (ß = 0.112, p = 0.014) analyses. CONCLUSIONS: The majority of concussions occurred during the late-season period. No difference in acute symptoms or recovery outcomes was seen when comparing the three regular season time points. Playoff concussions were associated with significantly increased symptom scores compared with nonplayoff concussions.

Recent Trends in Successful Neurosurgery Resident Matriculation: A Retrospective and Bibliometric Analysis.

BACKGROUND: Prior literature has demonstrated barriers to successful residency matching, including sex, medical school background, and international medical graduate status. Our aim is to characterize the recent trends in successfully-matched residents, with particular attention to geography and academic productivity. METHODS: Resident information, including demographics and educational background, was gathered from program websites. Bibliometric analysis focused on PubMed publications from the top neurosurgery journals. A top 20 medical school was defined using the US News Rankings for research in 2022. Regression analyses were performed to explore the associations between total and first-author publications and other relevant factors, correcting for graduate studies. RESULTS: A total of 114 institutions and 946 residents were included in the final analysis. Of the 845 with medical school information, 62 (7.3%) completed medical school internationally and 181 of 783 (23.1%) came from a top 20 medical school. Male residents had a higher proportion of residents with international undergraduate and international medical school degrees when compared to female residents [32 (7.5%) vs. 4 (2.4%), P = 0.021; 52 (8.6%) vs. 10 (4.2%), P = 0.026; respectively]. The multivariate regression analysis demonstrated a significant increase in publications for international medical school graduates (B = 8.3, P < 0.001), top tier medical school graduate (B = 1.3, P = 0.022), and male sex (B = 1.20, P = 0.019) for total number of publications. CONCLUSIONS: Geographical factors, reported sex, and graduation status have influenced how resident candidates are perceived. Understanding these trends is vital for future resident matching. Addressing gender and educational diversity is essential to foster inclusivity and research-driven environments in neurosurgery residency programs.

Symptoms of Traumatic Encephalopathy Syndrome are Common in Community-Dwelling Adults.

BACKGROUND AND OBJECTIVES: The consensus criteria for traumatic encephalopathy syndrome (TES), the possible in vivo clinical syndrome associated with significant repetitive head impacts, have only been minimally studied to date. This study examined the prevalence of the proposed core clinical features of TES in a sample of healthy adults. METHODS: A cross-sectional survey study was conducted through ResearchMatch, a national health volunteer registry. Participants were assessed for symptoms of TES based on the 2021 consensus criteria, including prior repetitive head impacts and core clinical features. Additional health information (e.g., concussion history, psychological health, sleep, chronic pain) was also evaluated. The consensus proposed research criteria for TES (i.e., reporting at least one progressive core clinical feature of TES, as in progressive difficulties with episodic memory, executive functioning, or neurobehavioral dysregulation) were applied to the sample. RESULTS: Out of 1100 participants (average age = 53.6 ± 17.7 years, 55% women), 34.6% endorsed one or more progressive core clinical features of TES. Participants with a significant history of contact sports (i.e., ≥ 5 years total, with ≥ 2 years in high school or beyond) had similar rates of endorsing a progressive core clinical feature of TES compared to those without significant histories of repetitive head impacts (36.4% vs 32.8%, respectively, χ2 = 0.52, p = 0.47). A significant history of repetitive head impacts in sports was not associated with endorsing a core clinical feature of TES in univariable or multivariable models (p > 0.47), whereas current depression/anxiety (odds ratio [OR] = 6.94), a history of psychiatric disorders (OR = 2.57), current sleep problems (OR = 1.56), and younger age (OR = 0.99) were significant predictors of TES status in a multivariable model. In a subsample of 541 participants who denied a lifetime history of contact sports, other forms of repetitive head impacts, and concussions, approximately 31.0% endorsed one or more progressive core clinical features of TES. Additionally, 73.5% of neurotrauma-naïve participants with current anxiety or depression reported at least one core progressive feature of TES, compared with 20.2% of those without clinically significant depression/anxiety symptoms. CONCLUSIONS: A considerable proportion of adults without a significant history of repetitive head impacts from sports endorsed core TES features, particularly those experiencing mental health symptoms. Having a significant history of contact sports was not associated with endorsing a core progressive clinical feature of TES, whereas other health factors were. These findings underscore the need for validating and refining TES criteria in samples with and without substantial neurotrauma histories.

Does Mechanism of Injury Affect Recovery After Sport-Related Concussion in Basketball? A Pilot Study.

BACKGROUND AND OBJECTIVES: Understanding sport-related concussion (SRC) mechanisms can aid in prevention and treatment. Concussions in basketball have received relatively less attention compared with collision sports. In a cohort of concussed high school basketball players, this pilot study sought to (1) describe the mechanisms of how concussions occur in basketball and (2) assess the relationship between mechanisms and acute symptomatology and recovery time. METHODS: A retrospective cohort, pilot study examined concussed adolescent athletes (aged 14-18 years) treated at a sports concussion center from 11/2017 to 04/2022. The primary independent variable was mechanism of injury, categorized into (1) contact (head-to-head, head-to-body, head-to-ball, head-to-ground), (2) player (offensive play, defensive play, both), and (3) awareness mechanisms (aware, unaware). The outcomes included acute symptom severity, time to return-to-learn, symptom resolution, and return-to-play. Associations between mechanisms and outcomes were analyzed using one-way analysis of variance, independent t-tests, multivariable linear regressions, and Cox regression. RESULTS: Of 105 basketball players (16.2 ± 1.4 years; 50.5% male), head-to-ground contact (n = 44/105; 41.9%) was most common. Taking-a-charge (n = 12/53; 22.6%) was the most frequent player mechanism, with similar rates for offensive (n = 24/53; 45.3%) and defensive (n = 23/53; 43.4%) plays. Most were aware of impending collision (n = 37/46; 80.4%). Head-to-body concussions were associated with higher initial symptoms severity scores when compared with head-to-head (ß = 0.33, P = .003) and head-to-ground (ß = 0.23, P = .050) contacts. Player and awareness mechanisms were not significant predictors of outcome measures. Only higher initial symptom scores were associated with a longer time to return-to-learn, symptom resolution, and return-to-play. CONCLUSION: In this pilot study of concussed high school basketball players, head-to-ground was the most common concussion mechanism, with similar rates during offensive and defensive plays. Although head-to-body contact increased acute symptoms, other mechanisms did not predict recovery time. Given the limited information on concussions in basketball, the preliminary results of this pilot study may help inform larger studies on basketball SRC mechanisms.

The association between motor and non-motor symptoms in essential tremor patients being evaluated for deep brain stimulation surgery.

BACKGROUND: Non-motor symptoms, including depression and cognitive impairment, are common in essential tremor (ET), but associations between these symptoms and tremor are poorly understood. METHODS: A retrospective, single-institution, cohort study evaluated 140 patients with ET undergoing evaluation for deep brain stimulation (DBS) surgery. The Fahn-Tolosa-Marin (FTM) or Washington Heights-Inwood Genetic Study of ET (WHIGET) scale was used to grade tremor. Tremor scores were divided into quartiles. Patients underwent clinical neuropsychological evaluations that included a comprehensive cognitive test battery and Beck Depression Inventory-II (BDI-II). Subgroup analysis was performed with groups who met criteria for depression (BDI-II > 14) or overall cognitive impairment (<9th percentile on at least two dissimilar cognitive tests). Independent samples t-tests were used for continuous variables and chi square tests for categorical variables. Univariable and multivariable regressions were used to determine relationships between tremor and non-motor scores. RESULTS: Tremor quartile was correlated with language domain performance (p = 0.044) but not depression scores. FTM score was associated with BDI-II (ß = 0.940, p = 0.010), language (ß = -0.936, p = 0.012), and visuospatial domain (ß = -0.836, p = 0.025) scores, such that worse tremor was associated with more depression and worse language and visuospatial function. WHIGET score was not associated with any neuropsychological scores on multivariable regression. CONCLUSION: FTM score was associated with language, visuospatial, and mood symptoms, suggesting a relationship between the severity of these symptom types. Different tremor scores capture different motor symptoms and relationships with nonmotor symptoms.

Analyzing Google Search Trends for Migraine Surgery and Nurtec in Response to Public Announcements.

Background: Nurtec, a versatile migraine medication, has gained popularity. However, the awareness of migraine surgery remains uncertain. Methods: Following a descriptive approach, this cross-sectional study used Google Trends data as of December 1, 2023, to analyze internet search patterns. Approval from Vanderbilt University's institutional review board and adherence to Strengthening the Reporting of Observational Studies in Epidemiology guidelines were confirmed. Monthly relative search volume (RSV) data for "migraine surgery," "Nurtec," and "Rimegepant" were collected from January 1, 2004, to November 11, 2023, within the United States. Statistical analysis involved determining mean monthly RSV values and percentage changes for critical periods. Results: For "Nurtec," a significant surge in RSV occurred from March 2020 to April 2020 (344%). Additional peaks were observed from June 2020 to July 2020 (66%), October 2020 to December 2020 (169%), May 2021 to June 2021 (33%), and May 2023 to June 2023 (14%). "Migraine surgery" exhibited a notable 400% increase in RSV, from March 2005 to May 2005. However, post-2006, RSV for "migraine surgery" consistently remained low without noticeable peaks. Conclusions: The analysis of RSV trends for "Nurtec" and "migraine surgery" from 2004 to 2023 reveals the impact of pivotal events and marketing strategies on public interest. The distinct peaks in "Nurtec" RSV align with Food & Drug Administration approvals and marketing campaigns, highlighting the medication's accessibility. Conversely, the consistently low RSV for "migraine surgery" indicates limited awareness, emphasizing the need for enhanced promotion and education regarding surgical interventions.

Current Trends in Autologous Breast Reconstruction and the Implications of Impending Changes to Insurance Reimbursement.

Introduction In 2019, the Centers for Medicare & Medicaid Services (CMS) combined all autologous breast flap procedures under one billing code, effective from December 31, 2024. This change will result in equal insurance reimbursement rates for popular flap options, such as transverse rectus abdominis muscle (TRAM) and deep inferior epigastric perforator (DIEP) flaps, which were previously billed separately using S-codes based on complexity. Methods This study aimed to analyze insurance code changes for autologous breast reconstruction flap procedures. Data were collected from the American Society of Plastic Surgeons' annual plastic surgery statistics reports, including specific insurance codes and case volumes from 2007 to 2020. A comprehensive analysis was conducted to assess recent trends in flap utilization rates, documenting any modifications or additions to the existing codes and their implementation years. Results The study analyzed billing codes and case volumes for autologous breast reconstruction procedures, with a focus on the DIEP flap and other alternatives. Non-autologous breast reconstruction procedures showed consistently higher case volumes compared to autologous procedures from 2007 to 2020. Notably, the popularity of the DIEP flap surpassed that of other flap options after 2011. Conclusion The removal of S-codes for autologous breast reconstruction by CMS and the subsequent potential decrease in insurance coverage for the DIEP flap may lead to a decrease in its utilization and a shift toward more invasive options, like the TRAM flap. This change could result in financial burdens for patients and widen socioeconomic disparities in breast reconstruction, limiting access to preferred reconstructive methods and impacting patient autonomy and overall well-being.

Current State of Brazilian Neurosurgery: Evaluation of Burden of Care and Case Volume.

BACKGROUND: Low- and middle-income countries (LMICs) bear a heavier burden of neurosurgical diseases than high-income countries. Brazil, a growing middle-income country, holds promise as a health care market. However, there exists a lack of information to characterize the state of neurosurgical practice and access to care in Brazil. This study aimed to characterize neurosurgical practice in Brazil and identify barriers to care. METHODS: A collaborative survey was developed with Brazilian neurosurgeons and distributed by the Brazilian Society of Neurosurgery. The survey gathered demographic information, practice characteristics, case volume, referral patterns, income sources, and assessed barriers using a Likert scale. Descriptive statistics were employed for data analysis. RESULTS: One-hundred and forty-nine neurosurgeons participated (response rate: 17.5%), representing various states in Brazil. Neurosurgeons practiced in more than 4 different hospital systems on average, with most consultations and procedures occurring in public hospitals. Common procedures included tumor surgeries, general neurosurgery, spine surgeries, trauma surgeries, and hydrocephalus management. Equipment shortage and systemic issues were identified as major barriers to care. CONCLUSIONS: Neurosurgical practice in Brazil exhibits diverse age distribution, widespread distribution across states, and involvement in both public and private hospitals. Survey insights shed light on neurosurgical workload and neurosurgical practice characterization. Lack of equipment and inadequate postoperative resources pose significant barriers to care. The findings highlight the need for investments in equipment, critical care facilities, and improved health care system coordination to enhance access to neurosurgical care in Brazil.

Does earlier vestibular therapy after sport-related concussion lead to faster recovery?

OBJECTIVE: Many patients experience vestibular dysfunction following a sport-related concussion (SRC). Vestibular rehabilitation therapy has recently become more well established. In a cohort of athletes with SRC, the authors sought to 1) assess the relationship between symptoms at the initial clinic visit and time to referral for vestibular therapy, and 2) evaluate whether earlier referral to vestibular therapy was associated with faster recovery, as defined as days to return to learn (RTL), symptom resolution (SR), and return to play (RTP). METHODS: A retrospective cohort study was conducted using a regional multidisciplinary concussion center's database. Patients aged 12-23 years diagnosed with SRC who received vestibular rehabilitation therapy between October 2017 and October 2021 were included. Demographics and Post-Concussion Symptom Scale (PCSS) scores were extracted. The independent variable of interest was time to vestibular therapy referral. The three outcome variables were RTL, SR, and RTP. Spearman's rho correlation (rho) was used to evaluate the relationship between total PCSS score and individual symptoms (balance problems, blurred vision, and dizziness) and time to referral for vestibular therapy. Multivariable linear regression was performed to determine the impact of time to vestibular therapy on the three outcomes of RTL, SR, and RTP. Covariates included initial symptom burden, age, and prior concussions. RESULTS: Forty-two concussed athletes were referred for vestibular therapy (mean age 16.8 ± 2.7 years; 54.8% female). The mean time from concussion to the initial clinic visit was 22.4 ± 20.2 days, and the mean time from the initial clinic visit to vestibular therapy referral was 4.9 ± 11.3 days. Initial total PCSS scores (rho[37] = 0.05, p = 0.78) and individual symptoms, including balance problems (rho[33] = -0.004, p = 0.98), blurred vision (rho[34] = -0.17, p = 0.33), and dizziness (rho[33] = 0.07, p = 0.67), were not correlated with time to referral for vestibular therapy. Multivariable linear regression analysis found that earlier vestibular therapy referral was predictive of shorter days to SR (p = 0.002) and RTP (p = 0.02) but not RTL (p = 0.59). CONCLUSIONS: In athletes with SRC referred for vestibular therapy, earlier vestibular therapy referral was significantly associated with faster time to RTP and SR. Future investigations should focus on identifying common postconcussive signs and symptoms that serve as indications for referral to vestibular therapy.

The Neurosurgery Match: COVID-19 Comparison and Bibliometric Analysis.

BACKGROUND: Because of the effect of COVID-19 on academic opportunities, as well as limitations on travel, away rotations and in-person interviews, COVID-19-related changes could impact the neurosurgical resident demographics. Our aim was to retrospectively review the demographics of the previous 4 years of neurosurgery residents, provide bibliometric analysis of successful applicants, and analyze for the effects of COVID-19 on the match cycle. METHODS: All American Association of Neurological Surgeons' residency program websites were examined for a list of demographic characteristics for current postgraduate years 1 to 4. Gathered information included gender, undergraduate and medical institution and state, medical degree status, and prior graduate programs. RESULTS: A total of 114 institutions and 946 residents were included in the final review. Most (676, or 71.5%) of the residents included in the analysis were male. Of the 783 who studied within the United States, 221 (28.2%) residents stayed within the same state of his or her medical school. Fewer residents (104 of 555, or 18.7%) stayed within the same state of his or her undergraduate school. Demographic information and geographic switching relative to medical school, undergraduate school, and hometown showed no significant changes between pre-COVID-19 and COVID-19-matched cohorts overall. The median number of publications per resident significantly increased for the COVID-19-matched cohort (median, 1; interquartile range [IQR], 0-4.75) when compared with the non-COVID-19-matched cohort (median, 1; IQR, 0-3, P = 0.004), as did first author publications (median, 1; IQR, 0-1 vs. median, 1; IQR, 0-1; P = 0.015), respectively. The number of residents matching into the same region in the Northeast relative to undergraduate degree was significantly greater after COVID-19 (56 [58%] versus 36 [42%], P = 0.026). The West demonstrated a significant increase in the mean number of total publications (4.0 ± 8.5 vs. 2.3 ± 4.2, P = 0.02) and first author publications (1.24 ± 2.33 vs. 0.68 ± 1.47, P = 0.02) after COVID-19, with the increase in first author publications being significant in a test of medians. CONCLUSIONS: Herein we characterized the most recently matched neurosurgery applicants, paying particular attention to changes over time in relation to the onset of the pandemic. Apart from publication volume, characteristics of residents and geographical preferences did not change with the influence of COVID-19-induced changes in the application process.

A Novel Orthoplastic Reconstruction of Relapsed Clubfoot With Total Ankle Arthroplasty.

Congenital clubfoot is addressed in infancy and rarely persists into adulthood. Ankle arthroplasty is an increasingly popular surgical intervention for patients with ankle arthritis since it allows a natural ankle range of motion and completely replaces a degenerative hindfoot. Here, we describe the first successful total ankle arthroplasty (TAA) for a patient with previously treated congenital clubfoot that reverted later in life. To address the patient's poor soft-tissue integument and reduce the likelihood of post-surgical complications, a perioperative latissimus muscle-free flap was performed. This two-staged, novel orthoplastic intervention addressed our patient's ankle issues and appears to be a viable option for clubfoot patients.
