RESUMO
OBJECTIVE: Magnetic resonance imaging (MRI) is increasingly used to evaluate patients with diffuse traumatic brain injury (dTBI). However, the utility of early MRI is understudied. We hypothesize that early MRI patients will have increased length of stay but no changes in intracranial pressure (ICP) management or disposition. METHODS: The 2019 National Trauma Data Bank was queried for patients with dTBI and Glasgow Coma Scale score ≤8. Extra-axial and focal intra-axial hemorrhages were excluded. Clinical characteristics were controlled for. Patients with and without MRI were compared for ICP management, outcome, mortality, and disposition. A propensity score matching algorithm was used to create a 1:1 match cohort. RESULTS: In 2568 patients, MRI was less common in severe dTBI patients with clear reasons for poor examination, including bilaterally unreactive pupils or midline shift. After matching, 501 patients who underwent MRI within 1 week were compared with 501 patients without MRI. Magnetic resonance imaging patients had longer intensive care unit stays (11.6 ± 9.6 vs. 13.4 ± 9.5, p < 0.01; 95% confidence interval [95% CI], -3.03 to -0.66). There was no difference between groups in ICP monitor (23.6% vs. 27.3%; p = 0.17; 95% CI, -0.09 to 0.02) or ventriculostomy placement (13.6% vs. 13.2%, p = 0.85; 95% CI, -0.04 to 0.05) or in withdrawal of care (15.0% vs. 18.6%, p = 0.12; 95% CI, -0.08 to 0.01). MRI patients were more likely to be discharged to inpatient rehabilitation (42.9% vs. 33.5%; p < 0.01; 95% CI, 0.03-0.15) but not to home (9.4% vs. 9.0%; p = 0.83; 95% CI, -0.03 to 0.04). CONCLUSION: The decision to pursue early brain MRI may be driven by lack of obvious reasons for a patient's poor neurologic status. MRI patients had longer intensive care unit stays but no difference in rates of placement of ICP monitors or ventriculostomies or withdrawal of care. Further study is required to define the role of early MRI in dTBI patients. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

OBJECTIVE: The use of anticoagulation to prevent venous thromboembolism (VTE) is controversial in the setting of neurosurgical decompression for traumatic subdural hematoma (SDH). In these patients, there is concern that anticoagulation may cause secondary hemorrhage, increasing the risk of death and other complications. Patients with a history of anticoagulant use are at further risk of VTE, but the effect of VTE prophylaxis (VTEP) following neurosurgery for SDH has not been thoroughly investigated in this population. This study aims to investigate the differences in in-hospital outcomes in patients with SDH and preexisting anticoagulant use who received VTEP following neurosurgical intervention compared with those who did not. METHODS: The National Trauma Data Bank was queried from 2017 to 2019 for all patients with preexisting anticoagulant use presenting with an SDH who subsequently underwent neurosurgical intervention. Patients who received VTEP were propensity score matched with patients who did not based on demographics, insurance type, injury severity, and comorbidities. Paired Student t-tests, Pearson's chi-square tests, and Benjamini-Hochberg multiple comparisons correction were used to compare differences in in-hospital complications, length of stay (LOS), and mortality rate between the two groups. A logistic regression model was developed to identify risk factors for in-hospital mortality. RESULTS: Two thousand seven hundred ninety-four patients matching the inclusion criteria were identified, of whom 950 received VTEP. Following one-to-one matching and multiple comparisons correction, the VTEP group had a lower mortality rate (18.53% vs 34.53%, p < 0.001) but longer LOS (14.09 vs 8.57 days, p < 0.001) and higher rates of pressure ulcers (2.11% vs 0.53%, p = 0.01), unplanned intensive care unit admission (9.05% vs 3.47%, p < 0.001), and unplanned intubation (9.47% vs 6.11%, p = 0.021). The multivariable logistic regression showed that use of unfractionated heparin (UH; OR 0.36, p < 0.001) and low-molecular-weight heparin (LMWH; OR 0.3, p < 0.001) were associated with lower odds of in-hospital mortality. CONCLUSIONS: In patients with traumatic SDH and a history of anticoagulant use, perioperative VTEP was associated with increased LOS but provided a mortality benefit. LMWH and UH use were the strongest predictors of survival.

Introduction: Neuropathic pain is a debilitating condition resulting from various etiologies such as diabetes, multiple sclerosis, and infection, and is associated with decreased quality of life, poor health outcomes, and increased economic burden. However, epidemiological studies on neuropathic pain have been largely limited in Vietnam. Methods: A cross-sectional study was conducted on adult Vietnamese industrial workers across three manufacturing plants. Demographic, socioeconomic, occupational and health data were collected. Prevalence of neuropathic pain was assessed using the Douleur Neuropathique 4 (DN4) scale. Regression modeling was utilized to identify predictors of pain. Results: Among 276 workers, 43.1 and 24.3% reported that they had suffered from spinal pain and osteoarthritis pain, respectively. In terms of work conditions, people maintaining constant posture when working from 30 to 60 min (OR = 3.15, 95% CI = 1.07; 9.29), or over 60 min (OR = 2.59; 95% CI = 1.12; 5.98) had a higher risk of suffering from spinal pain. People who worked in conditions lacking adequate lighting and with exposures to toxic chemicals were also likely to be suffering from osteoarthritis pain with OR = 4.26, 95% CI = 1.02; 17.74 and Coef. = 1.93; 95% CI = 1.49; 2.50, respectively. Regular health examinations and higher expenditure for healthcare were correlated with a lower prevalence of neuropathic pain. Discussion: These results may inform the adoption of pain screening and other programs that increase health care access for this population, as well as more stringent occupational health and safety standards.

PURPOSE: Workplace injury is a commonplace occurrence in the USA. Spine injuries are especially devastating as they can cause chronic pain and limit mobility which prevents patients from returning to work. Gaining a better understanding of the patients, mechanisms, and treatments associated with these injuries can aid in improving outcomes. The purpose of this study is to characterize the nature of work-related spine injuries. METHODS: The National Trauma Data Bank was queried from 2017 to 2019 for all diagnoses involving the cervical, thoracic, lumbar, and sacral spine. Patient demographics, comorbidities, injury characteristics, spinal diagnoses, and procedures were identified for each occupation. Occupational industries, patient demographics, mechanisms of injury, diagnoses, and spinal procedures were characterized. RESULTS: A total of 100,842 work-related injuries were identified between 2017 and 2019. Of those, 19,002 (19%) were spine injuries, and subsequently, 3963 (21%) required spinal surgery. Eight thousand twenty-nine (42%) cases were seen among construction workers, which had the highest proportion of Hispanic patients (36%). Smoking was prevalent in labor-intensive occupations with high rates of spine injury such as building and grounds maintenance. The most common mechanism of injury was a fall from a roof. The most common injury diagnoses were L1, L2, and L3 fractures, and the most common procedures were T12-L1 fusion, multilevel thoracic fusion, and multilevel lumbar fusion. CONCLUSION: Spine injuries represent a significant portion of work-related injuries in the USA and a considerable portion require neurosurgical intervention. Initial efforts should focus on the prevention and management of lumbar spine injuries in the construction industry.

OBJECTIVE: Cervical cord syndrome (CCS) is the most common type of incomplete spinal cord injury. Prompt surgical decompression within 24 hours increases neurologic function and rates of home discharge. Racial disparities exist in spinal cord injury, with Black patients experiencing longer lengths of stay and higher rates of complications than in White patients. This study aims to investigate potential racial disparities in time to surgical decompression in patients with CCS. METHODS: The National Trauma Data Bank (NTDB) was queried from 2017 to 2019 for patients who underwent surgery for CCS. The primary outcome was time from hospital admission to surgery. Student's t-test and Pearson's chi-squared test were used to evaluate differences in categorical and continuous variables, respectively. An uncensored Cox proportional hazards regression model was developed to assess the effect of race on surgical timing while adjusting for potential confounders. RESULTS: 1,076 patients with CCS resulting in cervical spinal cord surgery were included in the analysis. Regression analysis results showed that Black patients (HR=0.85, P = 0.03), female patients (HR=0.81, P < 0.01), and patients treated at community hospitals (HR=0.82, P = 0.01) were less likely to receive early surgery. CONCLUSIONS: Though the advantages of early surgical decompression in the setting of CCS have been detailed in medical literature, Black, and female patients experience lower rates of prompt surgery following hospital admission and higher rates of adverse outcomes. This disproportionately increased time to intervention exemplifies demographic disparities in the timely provision of treatment to patients with spinal cord injuries.
RESUMO
INTRODUCTION: Unfractionated heparin remains the most widely used agent in the prevention and acute treatment of thrombosis. Pharmacological complexities of this intriguing agent mandate frequent monitoring of its anticoagulant properties to maintain safe and effective hematological outcomes. Although activated partial thromboplastin time has been the standard test to monitor unfractionated heparin therapy for many decades, the anti-Xa assay has emerged as a substitute or adjunct in many institutions. AREAS COVERED: This brief report outlines the key features of anti-Xa assay in monitoring unfractionated heparin in acute management of thrombosis in various contemporary settings, with emphasis on evidence for clinical outcomes. PubMed.gov database was utilized to obtain the pertinent literature. EXPERT OPINION: The anti-Xa activity is primarily a reflection of UFH concentration and does not account for other hematological variables frequently present in contemporary anticoagulation management. The advantage of the anti-Xa assay in monitoring UFH therapy is predicated upon its limitations to account for global physiological hemostasis. There are significant disease and drug interactions that may potentially result in false in-vitro analysis of anti-Xa activity. Routine application of the anti-Xa assay is not evidence-based at this time.

As the lives of people living with HIV (PLWH) become increasingly normalized, more focus is being given to the associated comorbidities of HIV, including those related to mental health such as depression. This study aims to evaluate the correlation between depressive symptoms and HIV outcomes in Vietnam through the measurement of CD4 cell count. A mixed design was utilized, in which both a longitudinal assessment of CD4 cell counts and a cross-sectional survey of depressive symptoms were conducted on 481 patients in the Bach Mai and Ha Dong HIV clinics (Hanoi, Vietnam). CD4 cell count data was extracted from the medical records of participants, and depressive symptoms were screened using the Patient Health Questionnaire (PHQ-9). The results illustrate that the presence of moderately severe to severe depressive symptoms is associated with lower CD4 cell counts, indicating poorer HIV outcomes resulting from comorbid depression. This correlation was especially noticeable in the PHQ-9 items for psychomotor agitation/retardation (p < 0.05) and suicidal ideation (p < 0.05). Future policy and treatment options for HIV in Vietnam should consider the presence of comorbid mental health conditions in order to provide more suitable and effective treatment in the goal of providing a higher quality of life for PLWH.

INTRODUCTION: Osteoporotic vertebral compression fracture (OVCF) is a growing health care problem in today's aging population. Since the advent of kyphoplasty and vertebroplasty, these interventions have been commonly utilized in the treatment of symptomatic OVCF. However, the use of these interventions varies because there is not a standard of care for the management of OVCF. There remain disparities in the use of these procedures as treatment for OVCFs in the United States. METHODS: The 2012 to 2016 Nationwide Inpatient Sample was queried for all patients admitted for OVCF. These patients were then grouped based on whether they received conservative vs surgical (kyphoplasty/vertebroplasty) management and compared with respect to various socioeconomic factors including race, insurance coverage, income quartile, hospital control, and geography. Propensity score matching was utilized to control for potential baseline confounders as well as the influence of other endpoints. RESULTS: The search criteria identified 35,199 patients admitted with OVCF, of whom 7900 (22.4%) received spine augmentation. Blacks/African Americans (risk ratios [RR] = 0.79, P < 0.001), Hispanics/Latinos (RR = 0.82, P < 0.001), Asians/Pacific Islanders (RR = 0.81, P = 0.048), and unknown/other races (RR = 0.88, P = 0.037) were less likely to receive surgical management than whites/Caucasians. When compared with Medicare patients, those with Medicaid (RR = 0.76, P < 0.001) were less likely to receive surgery while privately insured patients were more likely (RR = 1.06, P = 0.42). Patients in the West (RR = 0.90, P < 0.001) were less likely to receive surgery for OVCF than those in the Northeast. CONCLUSIONS: A wide variety of socioeconomic disparities exists in the use of spinal augmentation for the management of OVCF in the United States, limiting patient access to a potentially beneficial procedure. CLINICAL RELEVANCE: Retrospective Analysis.
RESUMO
INTRODUCTION: Postlaminectomy syndrome (PLS), also known as failed back surgery syndrome, is the persistence of radicular pain in the face of surgical intervention. Despite its prevalence in 10 to 40% of spine surgery patients, outpatient pharmacologic and interventional management remains poorly characterized. METHODS: The 2007 to 2016 National Ambulatory Medical Care Survey (NAMCS) was utilized to include all outpatients diagnosed with PLS. For each visit, documented pain medications (opioids, nonsteroidal anti-inflammatory drugs [NSAIDs], neuropathic agents, etc) as well as patient demographics and comorbidities (sex, age, race, insurance coverage, and medical history) were recorded. The association between medication class and rate of prescription relative to sex was assessed in the population-weighted cohort, using propensity score matching to control for potential confounders. RESULTS: A total of 70,343 PLS patients were identified, including 36,313 (51.6%) women. After accounting for baseline demographics and comorbidity differences between male and female patients, men were 2 to 3 times more likely to be prescribed opioids (OR: 2.38; 95%CI: 2.30-2.46) and procedural interventions for PLS compared to the female cohort, while women utilized neuropathic agents (OR: 0.53; 95%CI: 0.51-0.55) and NSAIDs (OR: 0.68; 95%CI: 0.65-0.70) more frequently. CONCLUSION: Pain management in outpatients presenting with PLS-related pain consisted of higher opioid utilization for men and higher neuropathic agents and NSAIDs utilization for the female patients. CLINICAL RELEVANCE: This article is the first to shed light on disparities in pain management among patients with post-laminectomy syndrome.
RESUMO
BACKGROUND: There is unclear evidence regarding the optimal surgical approach for multilevel cervical spondylotic myelopathy (CSM). The objective of this study was to compare complications, outcomes, and narcotic use in anterior discectomy and fusion (ACDF) vs posterior decompression and fusion (PCDF) in CSM patients. STUDY DESIGN: Registry-based retrospective cohort analysis. METHODS: Patients undergoing 3-level ACDF or PCDF for CSM between 2007 and 2017 were identified from the Humana Claims Database using relevant procedure codes. Propensity score-matched groups were compared in regards to complications, outcomes, and narcotic use. RESULTS: Propensity score matching generated equal cohorts of 6124 patients. The posterior fusion group had a higher rate of urinary tract infection (OR 2.47, P < 0.0001), deep vein thrombosis (OR 1.90, P < 0.0001), and pulmonary embolism (OR 1.75, P < 0.0001). In regards to 30-day outcomes, the posterior approach demonstrated higher rates of stroke (OR 1.68, P < 0.0001), wound dehiscence (OR 5.59, P < 0.0001), Surgical site infection (SSI) (OR 4.76, P < 0.0001), wound revision surgery (OR 3.02, P < 0.0001), and all-cause readmission (OR 2.01, P < 0.0001). One-year outcomes revealed higher rates of pseudarthrosis (4.7% vs 2.0%, OR 2.43, P < 0.0001) and revision or extension surgery (OR 2.33, P < 0.0001) in the posterior fusion cohort. These patients also demonstrated significantly higher mean morphine milligram equivalent used at 30 days (OR 1.19, P < 0.0001), as well as 60 (OR 1.20, P < 0.0001), 90 (OR 1.21, P < 0.0001), and 120 (OR 1.21, P < 0.0001) days. CONCLUSIONS: This nationwide propensity-matched analysis of multilevel CSM patients found the posterior approach to be associated with increased rates of inpatient complications, wound complications, 30-day readmission, 1-year pseudarthrosis, and 1-year revision or extension surgery. These patients also demonstrated higher levels of narcotic use up to 120 days after surgery. CLINICAL RELEVANCE: The posterior approach for treatment of CSM may be associated with increased rates of short- and long-term complications in addition to increased narcotic consumption in comparison to the anterior approach.
RESUMO
OBJECTIVE: In the present retrospective cohort analysis, we examined the differences in baseline characteristics and peri- and postoperative outcomes stratified by 3 groups: cannabis abuse or dependence versus none, surgical versus endovascular treatment, and unruptured and ruptured intracranial aneurysms. METHODS: A study population of 26,868 patients was defined using the 2009-2016 National Inpatient Sample database. The baseline characteristics were compared between the cannabis and no-cannabis groups, and the traits that differed significantly were factored into the multivariate analysis using 1:1 propensity score matching. The matched groups were analyzed to compare the cannabis and no-cannabis cohorts for the following endpoints: mortality, length of stay, discharge disposition, total hospital charges, and several peri- and postoperative outcomes. RESULTS: In the surgically and endovascularly treated groups for unruptured intracranial aneurysms, those in the cannabis group were more likely to be male and younger and to smoke tobacco than were those in the no-cannabis group. After matching, no significant endpoint differences were noted. Similarly, in the surgically and endovascularly treated ruptured aneurysm groups, those in the cannabis group were more likely to be male and younger and to smoke tobacco. After matching, the cannabis group within the endovascular treatment group had had a longer length of stay and were more likely to have developed any hydrocephalus, obstructive hydrocephalus, sepsis, and acute kidney injury. Those in the cannabis group who had undergone surgery were more likely to have developed any hydrocephalus, specifically, communicating hydrocephalus. CONCLUSIONS: The cannabis group with ruptured intracranial aneurysms was more likely to experience certain adverse outcomes after surgical or endovascular treatment compared with the no-cannabis group. However, such was not the case for cannabis abusers treated for unruptured aneurysms.

OBJECTIVE: The US FDA uses evidence from clinical trials in its determination of safety and utility. However, these trials have often suffered from limited external validity and generalizability due to unrepresentative study populations with respect to clinical patient demographics. Section 907 of the FDA Safety and Innovation Act (FDASIA) of 2012 attempted to address this issue by mandating the reporting of certain study demographics in new device applications. However, no study has been performed on its effectiveness in the participant diversity of neurosurgical device trials. METHODS: The FDA premarket approval (PMA) online database was queried for all original neurosurgical device submissions from January 1, 2006, to December 31, 2019. Endpoints of the study included racial and gender demographics of reported effectiveness trials, which were summated for each submission. Chi-square tests were performed on both endpoints for before and after years of FDASIA passage and implementation. RESULTS: A total of 33 device approvals were analyzed, with 14 occurring before SIA implementation and 19 after. Most trials (96.97%) reported gender to the FDA, while 66.67% reported race and 63.64% reported ethnicity. Gender breakdown did not change significantly post-SIA (53.30% female, p = 0.884). Racial breakdown was significantly different from the 2010 US Census for all races (p < 0.001) both pre- and post-SIA. Only Native American race was significantly different in terms of representation post-SIA, increasing from 0% to 0.63% (p = 0.0187). There was no significant change in ethnicity. CONCLUSIONS: The FDASIA, as currently written, does not appear to have had a significant impact on the racial or gender diversity of neurosurgical device clinical trial populations. This may be due to the noncompulsory nature of its guidance, or a lack of more stringent regulation on the composition of clinical trials themselves.

BACKGROUND: Readmission after coronary artery bypass grafting (CABG) is associated with adverse outcomes and increased cost. We evaluated the impact of a high-value care discharge protocol on readmission, length of stay (LOS), and discharge destination in patients undergoing isolated CABG. METHODS: In 2016, a comprehensive, patient-centered discharge protocol was implemented. A nurse practitioner was the fulcrum of this program, which focused on improving health literacy, disease management, and rigorous follow-up. All patients undergoing isolated CABG between 2012 and 2019 were retrospectively analyzed with regard to 30-day readmission, LOS, and discharge disposition. Differences were analyzed by Mann-Whitney, chi-square, and t tests. Analyses were repeated using propensity matching. RESULTS: A total of 910 consecutive patients undergoing isolated CABG were included in the analyses: 353 preprotocol and 557 postprotocol. Preprotocol patients had a readmission rate of 14.4% (n = 51), compared with 6.8% (n = 38) in the postprotocol patients (P < .001). Median postoperative LOS before implementation was 6 (interquartile range, 5-8) days compared with 5 (interquartile range, 4-6) days postimplementation (P < .001). Postimplementation, a higher proportion of patients were discharged to home compared with a skilled nursing facility (82.7% [n = 461] vs 73.9% [n = 261]; P = .002). After propensity matching, 298 well-balanced patients were included for analysis and these significant reductions in LOS, readmission, and discharge destination persisted. CONCLUSIONS: Implementation of a new discharge protocol was significantly associated with reduced readmission and LOS, along with higher rates of discharge to home in isolated CABG patients. Importantly, the results were sustainable and did not require additional resources, delivering high-value care.

BACKGROUND: Given the vasculopathic nature of moyamoya disease (MMD) and high susceptibility to ischemic events, patients with MMD often require surgical revascularization via an indirect or direct bypass, and analysis of disparities in receipt of appropriate management is critical. METHODS: The 2012-2016 Nationwide Inpatient Sample was queried for patients admitted with a diagnosis of MMD using International Classification of Diseases codes. Patient baseline demographics, hospital characteristics, and associated symptoms were collected. Patients were grouped by receipt of bypass procedure, and propensity score matching was performed to identify socioeconomic disparities between operative and nonoperative groups. RESULTS: Inclusion criteria were met by 4474 patients (827 pediatric patients and 3647 adult patients). Mean (SD) age for pediatric patients was 10.4 (4.6) years and for adult patients was 40.5 (14.4) years. Among pediatric patients, Black and Hispanic/Latino patients were less likely to undergo revascularization surgery (odds ratio [OR] 0.49, 95% confidence interval [CI] 0.21-0.78, P ≤ 0.01; OR 0.47, 95% CI 0.26-0.84, P = < 0.01, respectively); among adult patients, Black and Hispanic/Latino patients were similarly less likely to undergo bypass procedures (OR 0.60, 95% CI 0.49-0.72, P ≤ 0.01; OR 0.73, 95% CI 0.55-0.96, P = 0.01, respectively). Pediatric and adult patients in the lowest and next to lowest income quartiles were also less likely to receive operative treatment (pediatric patients: OR 0.61, 95% CI 0.40-0.94, P = 0.02; OR 0.64, 95% CI 0.42-0.98, P = 0.04, respectively; adult patients: OR 0.82, 95% CI 0.88-0.98, P = 0.03). CONCLUSIONS: Further investigation into socioeconomic disparities in adult and pediatric patients with MMD is warranted given the potential for inequities in access to appropriate intervention.

OBJECTIVE: Chiari malformation type 1 (CM-1) is a congenital neurologic condition in which the cerebellar tonsils herniate below the foramen magnum, resulting in symptoms such as headache and neck pain. Two common surgical treatment approaches are posterior fossa decompression with (PFDD) and without duraplasty (PFD). Previous single-center studies have demonstrated increased neurologic complications after PFDD compared to PFD. The goal of this study is to determine differences in inpatient complications and hospitalization data among patients treated with these surgical techniques using a nationwide sample. METHODS: The National Inpatient Sample (NIS) was queried for years 2012-2015 for all patients with a primary diagnosis of CM-1 who underwent PFD or PFDD. Differences in baseline demographics and comorbidities were accounted for in subsequent analysis using propensity score matching. Hospitalization measures and inpatient complications of the two cohorts were compared using Chi-squared tests and t-tests when appropriate. RESULTS: A total of 2395 patients with CM-1 were included in this study, with 750 (31.3%) undergoing PFD and 1645 (68.7%) undergoing PFDD. PFDD was associated with higher total hospital costs than PFD. There were no significant differences in other hospitalization or discharge data, non-neurologic complications, or CNS complications (CSF leak, pseudomeningocele, abscess, meningitis, stroke) between the two surgical groups. CONCLUSIONS: This study represents the largest national analysis to date of adult CM-1 patients undergoing PFD or PFDD. Our findings suggest that whether the decision is made to perform the less invasive PFD or more invasive PFDD, inpatient complications and hospitalization data will not significantly differ.

Objective: Characterize practice patterns and acute (30-day) surgical complications following fenestration and shunt procedures for the treatment of cerebral cysts in pediatric patients.Methods: This study utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Pediatric database. Patients were identified by International Classification of Disease codes for cerebral cysts and Current Procedural Terminology codes for shunting or fenestration. Demographic data, preoperative comorbidities, and postoperative complications were compared between the two procedures.Results: 741 patients were included in the data analysis, with a majority aged 4 years or younger (55.9%) and a male predominance (62.6%). Fenestration was performed in 590 (79.6%) patients. Primary shunting was performed in 151 (20.4%) patients. Patients who received shunts were more commonly aged 0-4 years and had proportionately worse preoperative health status. No statistically significant differences in postoperative complications were detected. Reoperation rate was 7.9% and 8.6% in the shunt and fenestration groups, respectively. Common reasons for reoperation were shunt revision or replacement and shunt placement after fenestration. Patients requiring shunting after a failed fenestration tended to be younger with higher American Society of Anesthesiologists (ASA) classification.Discussion: Fenestrations are performed more often than shunting. Generally, children who receive shunts are younger than those who undergo fenestration. Acute surgical risk appears to be similar for both operations.

Background: The optimal timing of ventriculoperitoneal shunt (VPS) and gastrostomy placement, relative to the safety of simultaneous versus staged surgery, has not been clearly delineated in the literature.Objective: To study the optimal inter-procedural timing relative to distal VPS infection and pertinent reoperation.Methods: A fifteen-year, retrospective, single-center study was conducted on adults undergoing VPS and gastrostomy within 30-days. Patients were grouped according to inter-procedural interval: 0-24 hr (immediate), 24 hr-7 days (early), and 7-30 days (delayed). The primary endpoint of the study was VPS infection and distal shunt complications requiring reoperation. Potential predictors of the primary end point (baseline cohort characteristics, procedural factors) were examined with standard statistical methods.Results: A total of 188 patients met inclusion criteria. The average interval between procedures was 7 ± 6 days, with 43.1% undergoing VPS prior to gastrostomy. Primary endpoint was encountered in 5 patients (2.7%): 1 (5.9%) of 17 patients undergoing immediate placement, 3 (2.8%) of 107 with early placement, and 1 (1.6%) of 64 with delayed placement. Although not statistically significant, 3.7% of patients undergoing VPS first had the primary endpoint, compared to 1.9% of those with gastrostomy. There were no statistically significant associations between the primary outcome and peri-operative CSF counts, gastrostomy modality, hydrocephalus etiology, chronic steroid use, or extended antibiotic administration.Conclusion: Although the low overall event rate in this cohort precludes definitive determination regarding differential safety, the data generally support a practice of performing the procedures >24-hours apart, with placement of gastrostomy prior to VPS.

BACKGROUND: Moyamoya disease is a chronic occlusive cerebrovascular disease that can present with either hemorrhagic or ischemic symptoms. The objective of this study was to evaluate whether the symptomatology of Moyamoya disease differs according to patient demographic groups. METHODS: In this study, we used the Nationwide Inpatient Sample (NIS) to investigate differences in the presentation of Moyamoya disease by age group, gender, and ethnicity from 2012 to 2016. After propensity score matching was utilized to control for overall comorbidity, the matched cohorts for each symptomatology were compared using a Chi-square test with respect to the potential risk factors of interest (i.e. age, sex, ethnicity) in order to generate multivariate reported P-values. RESULTS: A total of 4,474 patients met inclusion criteria. Patients presenting with ischemic stroke were more likely to be 65 years and older (p < 0.001); patients presenting with intracranial hemorrhage (ICH) were more likely to be 65 years and older (p < 0.001), male (p = 0.027), and Asian (p = 0.007); those presenting with seizure were more likely to be less than 10 years old (p = 0.002) and African American (p < 0.001); and those presenting with headache were more likely to be between 10 and 19 years old (p = 0.008). CONCLUSIONS: Our findings demonstrate that the distinct presentations of Moyamoya are associated with patient age, gender, and race. This is the largest study of its kind and adds to the collective understanding of this rare but life-threatening condition.

BACKGROUND: Computer-assisted navigation (CAN) has been shown to improve accuracy of screw placement in procedures involving the posterior cervical spine, but whether the addition of CAN affects complication rates, neurologic or otherwise, is presently unknown. The objective of this study is to determine the effect of spinal CAN on short-term clinical outcomes following posterior cervical fusion. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2011 to 2018. Patients receiving posterior cervical fusion were identified and separated into CAN and non-CAN cohorts on the basis of a propensity score matching algorithm to select similar patients for comparison. Rates of 30-day unplanned readmission, reoperation, and other complications were evaluated. A separate matching algorithm was used to generate a subgroup of patients undergoing C1-C2 or occiput-C2 fusion for comparison of the same outcomes. RESULTS: A total of 12,578 patients met inclusion criteria, of which 689 received CAN and 11,889 did not. After adjusting for baseline differences, patients receiving CAN experienced longer operations and had higher total relative value units associated with care. There were no significant differences in 30-day complication, readmission, or revision rates. At the occipitocervical junction, there were more hardware revisions in the non-CAN group, but this effect did not reach statistical significance (2 vs. 0; P = 0.155). CONCLUSIONS: Surgeons should embrace navigation in the cervical spine at their own discretion, as use of CAN does not appear to be associated with increased rates of surgical complications or readmissions despite longer operative time.
