Item Cribside Neurosonography: Real-Time Sonography for Intracranial Investigation of the Neonate(American Society of Neuroradiology, 1981) Edwards, Mary K.; Brown, David L.; Muller, Jans; Grossman, Charles B.; Chua, Gonzalo T.; Radiology and Imaging Sciences, School of MedicineA prospective study was made of 94 real-time sonographic sector scans of 56 neonates in a 6 month period. The examinations were performed using the anterior fontanelle as an acoustic window. In 17 cases, computed tomography (CT) head scans were available for comparison. In no case did the CT and sonographic examination disagree as to the size of the lateral ventricles. Abnormalities detected by sonography include ventriculomegaly, intracerebral hematomas, a congenital glioma, and several cystic lesions. Sonographic sector scanning produces excellent, detailed images of dilated lateral and third ventricles, uses no ionizing radiation, is less expensive than CT, and can be performed in the isolette, minimizing the risk of hypoxia and hypothermia. At Methodist Hospital Graduate Medical Center, sonography has replaced CT as the initial method of investigation of ventricular size. CT plays a complementary role in the evaluation of the posterior fossa, intracranial hemorrhage, and mass lesions.Item Disparities and guideline adherence in drugs of abuse screening in intracerebral hemorrhage(American Academy of Neurology, 2017-01-17) Tormoehlen, Laura M.; Blatsioris, Ashley D.; Moser, Elizabeth A.S.; Carter, Ravan J.L.; Stevenson, Alec; Ofner, Susan; Hulin, Abigail L.; O’Neill, Darren P.; Cohen-Gadol, Aaron A.; Leipzig, Thomas J.; Williams, Linda S.; Mackey, Jason; Neurology, School of MedicineOBJECTIVE: To characterize the pattern of urine drug screening in a cohort of intracerebral hemorrhage (ICH) patients at our academic centers. METHODS: We identified cases of primary ICH occurring from 2009 to 2011 in our academic centers. Demographic data, imaging characteristics, processes of care, and short-term outcomes were ascertained. We performed logistic regression to identify predictors for screening and evaluated preguideline and postguideline reiteration screening patterns. RESULTS: We identified 610 patients with primary ICH in 2009-2011; 379 (62.1%) were initially evaluated at an outside hospital. Overall, 142/610 (23.3%) patients were screened, with 21 positive for cocaine and 3 for amphetamine. Of patients <55 years of age, only 65/140 (46.4%) were screened. Black patients <55 years of age were screened more than nonblack patients <55 years of age (38/61 [62.3%] vs 27/79 [34.2%]; p = 0.0009). In the best multivariable model, age group (p = 0.0001), black race (p = 0.4529), first Glasgow Coma Scale score (p = 0.0492), current smoking (p < 0.0001), and age group × black race (p = 0.0097) were associated with screening. Guideline reiteration in 2010 did not improve the proportion <55 years of age who were screened: 42/74 (56.8%) were screened before and 23/66 (34.9%) after (p = 0.01). CONCLUSIONS: We found disparities in drugs of abuse (DOA) screening and suboptimal guideline adherence. Systematic efforts to improve screening for DOA are warranted. Improved identification of sympathomimetic exposure may improve etiologic classification and influence decision-making and prognosis counseling.Item Genetic predictors of severe intraventricular hemorrhage in extremely low-birthweight infants(Springer Nature, 2021) Thornburg, Courtney D.; Erickson, Stephen W.; Page, Grier P.; Clark, Erin A. S.; DeAngelis, Margaret M.; Hartnett, M. Elizabeth; Goldstein, Ricki F.; Dagle, John M.; Murray, Jeffrey C.; Poindexter, Brenda B.; Das, Abhik; Cotten, C. Michael; Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network; Pediatrics, School of MedicineObjective: To test associations between grades 3 or 4 (severe) intraventricular hemorrhage (IVH) and single nucleotide polymorphisms (SNPs) associated with coagulation, inflammation, angiogenesis, and organ development in an exploratory study. Study design: Extremely low-birthweight (ELBW) infants enrolled in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network's (NRN) Cytokines Study were included if they had cranial ultrasound (CUS) and genotyping data available in the NRN Anonymized DNA Repository and Database. Associations between SNPs and IVH severity were tested with multivariable logistic regression analysis. Result: One hundred thirty-nine infants with severe IVH and 687 infants with grade 1 or 0 IVH were included. One thousand two hundred seventy-nine SNPs were genotyped. Thirteen were preliminarily associated with severe IVH including five related to central nervous system (CNS) neuronal and neurovascular development. Conclusion: Genetic variants for CNS neuronal and neurovascular development may be associated with severe IVH in premature infants.Item Geographic Disparities in Case Fatality and Discharge Disposition Among Patients With Primary Intracerebral Hemorrhage(American Heart Association, 2023) Bako, Abdulaziz T.; Potter, Thomas; Pan, Alan; Tannous, Jonika; Rahman, Omar; Langefeld, Carl; Woo, Daniel; Britz, Gavin; Vahidy, Farhaan S.; Medicine, School of MedicineBackground: We evaluate nationwide trends and urban–rural disparities in case fatality (in‐hospital mortality) and discharge dispositions among patients with primary intracerebral hemorrhage (ICH). Methods and Results: In this repeated cross‐sectional study, we identified adult patients (≥18 years of age) with primary ICH from the National Inpatient Sample (2004–2018). Using a series of survey design Poisson regression models, with hospital location–time interaction, we report the adjusted risk ratio (aRR), 95% CI, and average marginal effect (AME) for factors associated with ICH case fatality and discharge dispositions. We performed a stratified analysis of each model among patients with extreme loss of function and minor to major loss of function. We identified 908 557 primary ICH hospitalizations (overall mean age [SD], 69.0 [15.0] years; 445 301 [49.0%] women; 49 884 [5.5%] rural ICH hospitalizations). The crude ICH case fatality rate was 25.3% (urban hospitals: 24.9%, rural hospitals:32.5%). Urban (versus rural) hospital patients had a lower likelihood of ICH case fatality (aRR, 0.86 [95% CI, 0.83–0.89]). ICH case fatality is declining over time; however, it is declining faster in urban hospitals (AME, −0.049 [95% CI, −0.051 to −0.047]) compared with rural hospitals (AME, −0.034 [95% CI, −0.040 to −0.027]). Conversely, home discharge is increasing significantly among urban hospitals (AME, 0.011 [95% CI, 0.008–0.014]) but not significantly changing in rural hospitals (AME, −0.001 [95% CI, −0.010 to 0.007]). Among patients with extreme loss of function, hospital location was not significantly associated with ICH case fatality or home discharge. Conclusions: Improving access to neurocritical care resources, particularly in resource‐limited communities, may reduce the ICH outcomes disparity gap.Item Revisiting germinal matrix and ventricular lining cells in cerebrospinal fluid: Potential mimickers of intracranial malignancy(Wiley, 2021-03) Wysozan, Timothy R.; Gulati, Rohit; Pathology and Laboratory Medicine, School of MedicineItem Viscoelastic Testing and Coagulopathy of Traumatic Brain Injury(MDPI, 2021-10-28) Bradbury, Jamie L.; Thomas, Scott G.; Sorg, Nikki R.; Mjaess, Nicolas; Berquist, Margaret R.; Brenner, Toby J.; Langford, Jack H.; Marsee, Mathew K.; Moody, Ashton N.; Bunch, Connor M.; Sing, Sandeep R.; Al-Fadhl, Mahmoud D.; Salamah, Qussai; Saleh, Tarek; Patel, Neal B.; Shaikh, Kashif A.; Smith, Stephen M.; Langheinrich, Walter S.; Fulkerson, Daniel H.; Sixta, Sherry; Neurological Surgery, School of MedicineA unique coagulopathy often manifests following traumatic brain injury, leading the clinician down a difficult decision path on appropriate prophylaxis and therapy. Conventional coagulation assays—such as prothrombin time, partial thromboplastin time, and international normalized ratio—have historically been utilized to assess hemostasis and guide treatment following traumatic brain injury. However, these plasma-based assays alone often lack the sensitivity to diagnose and adequately treat coagulopathy associated with traumatic brain injury. Here, we review the whole blood coagulation assays termed viscoelastic tests and their use in traumatic brain injury. Modified viscoelastic tests with platelet function assays have helped elucidate the underlying pathophysiology and guide clinical decisions in a goal-directed fashion. Platelet dysfunction appears to underlie most coagulopathies in this patient population, particularly at the adenosine diphosphate and/or arachidonic acid receptors. Future research will focus not only on the utility of viscoelastic tests in diagnosing coagulopathy in traumatic brain injury, but also on better defining the use of these tests as evidence-based and/or precision-based tools to improve patient outcomes.
