RESUMO
BACKGROUND: Takotsubo cardiomyopathy (TC) is a commonly observed complication among patients with intracerebral hemorrhage (ICH); however, the incidence of TC in patients with ICH have not been investigated yet. The goal of this study was to examine the incidence of TC in ICH and identify its risk factors, incidence rate, and outcomes of TC in patients with ICH in a US nationwide scale. METHODS: Data for patients with ICH between the years of 2015 and 2018 were extracted from the Nationwide Inpatient Sample and stratified based on the diagnosis of TC. RESULTS: Our results showed that the incidence rate of TC in ICH discharges was 0.27% (95% confidence interval [CI] 0.24-0.31). The mean age of patients with ICH developing TC was 66.28 years ± 17.11. There were significantly more women in the TC group, with an odds ratio (OR) of 3.65 (95% CI 2.63-5.05). Acute myocardial infarction (OR 7.91, 95% CI 5.80-10.80) was significantly higher in the TC group. The mortality rate of patients with ICH who had TC was significantly higher (33.48%, p < 0.0001). Length of stay (mean days; 15.72 ± 13.56 vs. 9.56 ± 14.10, p < 0.0001) significantly increased in patients with ICH who had TC. Patients with intraventricular ICH (OR 2.46, 95% CI 1.88-3.22) had the highest odds of TC. CONCLUSIONS: Takotsubo cardiomyopathy is associated with a higher mortality, longer hospitalization period, and more acute myocardial infarctions in patients with ICH. It is illustrated that intraventricular ICH is associated with higher odds of TC.

OBJECTIVE: Takotsubo cardiomyopathy (TC) is a stress-induced cardiomyopathy that can be precipitated by aneurysmal subarachnoid hemorrhage (aSAH). Several studies have shown patients who develop TC following aSAH have an increased risk of disability and mortality. The goal of this study is to examine the incidence of TC in aSAH, identify its risk factors, and analyze its impact on patient outcomes. METHODS: Data for patients with aSAH between the years of 2009 and 2018 were extracted from the Nationwide Inpatient Sample (NIS) and stratified based on the diagnosis of TC. Univariate analysis was used to assess the incidence of TC and covariates including patient demographics, aneurysmal treatment, in-hospital mortality rate, length of stay and costs. Multivariate logistic regression models analyzed the relationship between TC and these variables RESULTS: 80,915 aSAH patient-discharges were included in this study, 673 (0.83%) of which, developed TC. Females (OR 3.49, CI [2.82-4.33], P < 0.001), white ethnicity (69% vs 63%, P = 0.003) and patients with certain comorbidities including smoking (OR 1.64, CI [1.38-1.95], P < 0.0001) and seizures (OR 1.32, CI [1.07, 1.64], P = 0.01) were most likely to develop TC. Patients who developed TC had significantly increased mortality (OR 1.36, CI [1.13-1.65], P = 0.001), hospital stays (mean days of 19.4 vs 11.5, P < 0.0001), and costs ($104,111 vs $48,734, P < 0.0001). Hypertension (OR 0.63, CI [0.54-0.74], P < 0.0001) and hyperlipidemia (OR 0.63, CI [0.51-0.77], P < 0.0001) were found to be protective against TC. Patients with TC after acute SAH were more likely to undergo endovascular coiling (OR 1.68, CI [1.327-2.127], P < 0.001) rather than surgical clipping (OR 0.66, CI [0.52-0.83], P < 0.0001). CONCLUSIONS: Female sex, white ethnicity, smoking and seizures represented significant predictors of developing TC after aSAH, while hypercholesterolemia and hypertension were protective.

Skull bone graft failure is a potential complication of autologous cranioplasty after decompressive craniectomy (DC). Our objective was to investigate the association of graft size with subsequent bone graft failure after autologous cranioplasty. This single-center retrospective cohort study included patients age ≥18 years who underwent primary autologous cranioplasty between 2010 and 2017. The primary outcome was bone flap failure requiring graft removal. Demographic, clinical, and radiographic factors were recorded; three-dimensional (3D) reconstructive imaging was used to perform accurate measurements. Univariate and multi-variate regression analysis were performed to identify risk factors for the primary outcome. Of the 131 patients who underwent primary autologous cranioplasty, 25 (19.0%) underwent removal of the graft after identification of bone flap necrosis on computed tomography (CT); 16 (64%) of these were culture positive. The mean surface area of craniectomy defect was 128.5 cm2 for patients with bone necrosis and 114.9 cm2 for those without bone necrosis. Linear regression analysis demonstrated that size of craniectomy defect was independently associated with subsequent bone flap failure; logistic regression analysis demonstrated a defect area >125 cm2 was independently associated with failure (odds ratio [OR] 3.29; confidence interval [CI]: 0.249-2.135). Patient- and operation-specific variables were not significant predictors of bone necrosis. Our results showed that increased size of antecedent DC is an independent risk factor for bone flap failure after autologous cranioplasty. Given these findings, clinicians should consider the increased potential of bone flap failure after autologous cranioplasty among patients whose initial DC was >125 cm2.
RESUMO
OBJECTIVE: This study investigates the effect of aneurysm circulation on mortality and patient outcomes after aneurysmal subarachnoid hemorrhage (SAH) within the United States. METHODS: A retrospective cohort study was conducted using the Nationwide Inpatient Sample (NIS), a part of the Healthcare Cost and Utilization Project (HCUP), with ICD-10 codes for non-traumatic SAH between 2015-2016. Aneurysms were stratified as either anterior or posterior circulation. Multivariate logistic regression was used to find the impact of selected variables on the odds of mortality. RESULTS: The NIS reported 1,892 cases of non-traumatic SAH within the study period that were predominantly anterior circulation (82.6%), female (68.6%), white (57.7%), with mean age of 59.07 years, and in-hospital mortality of 21.4%. Anterior circulation aneurysms were associated with lower severity of initial illness (pâ¯=â¯0.014) but higher likelihood of vasospasm (pâ¯=â¯0.0006) than those of the posterior circulation. In a multivariate logistic regression analysis, mortality was associated with posterior circulation aneurysms (OR: 1.42; CI 95% 1.005-20.10, pâ¯=â¯0.047), increasing age (OR: 1.035; 95% CI 1.022-1.049; p < 0.0001), and shorter hospital stays (OR: 0.7838; 95% CI 0.758-0.811; p < 0.0001). Smoking history (OR: 0.825; 95% CI 0.573-1.187, p > 0.05) and vasospasm (OR: 1.005; 95% CI 0.648-1.558; p > 0.05) were not significantly associated with higher odds of mortality. CONCLUSIONS: Mortality following aneurysmal SAH is associated with posterior circulation aneurysms, and increasing age, but not smoking history or vasospasm. These findings may be useful for prognostication and counseling patients and families.

BACKGROUND: This report highlights a rapidly progressive case of Creutzfeldt-Jakob Disease (CJD) whose time from symptom onset to death spanned less than two months. We also explore the most recently available in-patient demographics data for discharges with CJD in the United States. METHODS: We reviewed a CJD case and systematically analyzed a retrospective cohort of CJD discharges using the Healthcare Cost and Utilization Project (HCUP) to evaluate the existing national data on the status of CJD demographics and dispositions in the United States in 2016. RESULTS: An estimated total of 710 hospital discharges with a diagnosis of CJD were seen across the United States in 2016. According to HCUP, the average age of patients was 66.15⯱â¯11.54 years with 48.6 % female. Average time to intubation from admission to hospital was 4.71⯱â¯7.32 days with a rate of intubation of 6.34 %. The mean hospital cost was $19,901.25 ± $18,743.48. The rate of in-hospital mortality was 8.45 %. No significant geographical differences were noted (pâ¯=â¯0.49). No significant differences were seen among incidence in specific ethnic groups (pâ¯=â¯0.33) or income quartiles (pâ¯=â¯0.90). CONCLUSIONS: Our data shows that the incidence of CJD in 2016 appears to be equally distributed among individuals in the United States by demographic categories. Additionally, our case-study from 2019 illustrates an important example for diagnosing a rapidly-progressing case of CJD.

BACKGROUND: The ARUBA trial (A Randomized Trial of Unruptured Brain Arteriovenous Malformations) was the first randomized control trial to investigate unruptured cerebral arteriovenous malformation (cAVM) treatments and concluded that medical management was superior to interventional therapy for the treatment of unruptured cAVMs. This conclusion generated considerable controversy and was followed by rebuttals and meta-analyses of the ARUBA methodology and results. We sought to determine whether the ARUBA results altered treatment trends of cAVMs within the United States. METHODS: Using the National Inpatient Sample, the largest all-payer inpatient care database within the United States, we isolated patients who were admitted on an elective basis for cAVM treatment and determined the treatment modality undergone by these patients. The cohort was dichotomized separately at 2 ARUBA time points: the European Stroke Conference presentation in May 2013, and The Lancet publication in February 2014. RESULTS: We found that the overall treatment rate of unruptured cAVMs decreased after both time points. However, the rate of surgical excision alone, relative to other modalities, was significantly increased, and endovascular intervention demonstrated a nonsignificant decrease. CONCLUSIONS: Our findings suggest that the ARUBA trial has influenced unruptured cAVM treatment patterns within the United States. Although the overall treatment rate has decreased, unruptured cAVMs, when treated post-ARUBA, are most commonly approached with surgical excision alone.

BACKGROUND: Socio-demographic factors have been suggested to contribute to differences in healthcare utilization for several elective orthopedic procedures. Reports on disparities in utilization of orthopedic trauma procedures remain limited. The purpose of our study is to assess the roles of clinical and socio-demographic variables in utilization of operative fixation of calcaneus fractures in the USA. METHODS: The National Inpatient Sample (NIS) dataset was used to analyze all patients from 2005 to 2014 with closed calcaneal fractures. Multivariate logistic regression analyses were performed to evaluate the impact of clinical and socio-demographic variables on the utilization of surgical versus non-surgical treatment. RESULTS: A total of 17,156 patients with closed calcaneus fractures were identified. Operative treatment was rendered in 7039 patients (41.03%). A multivariate logistic regression demonstrated multiple clinical and socio-demographic factors to significantly influence the utilization of surgical treatment including age, gender, insurance status, race/ethnicity, income, diabetes, peripheral vascular disease, psychosis, drug abuse, and alcohol abuse (p < 0.05). In addition, hospital size and hospital type (teaching versus non-teaching) showed a statistically significant difference (p < 0.05). CONCLUSIONS: Besides different clinical variables, we identified several socio-demographic factors influencing the utilization of surgical treatment of calcaneus fractures in the US patient population. Further studies need to identify the specific patient-related, provider-related, and system-related factors leading to these disparities.

OBJECTIVE: Multiple studies have shown worse outcomes in patients admitted for medical and surgical conditions on the weekend. However, past literature analyzing this "weekend effect" on subarachnoid hemorrhage (SAH) found no significant increase in mortality. This study utilizes more recent data to re-evaluate the association between weekend admission and mortality of patients hospitalized for SAH. METHODS: This retrospective cohort study queried the SAH patients in the Nationwide Inpatient Sample (NIS) database who were discharged from 2006 through 2014 during the weekend. RESULTS: Of the 54,703 admissions for SAH identified during the study period, 14,821 (27.1%) occurred over the weekend. Patients admitted over the weekend had a mean age of 59.2 years and were most likely to be female (59.6%), to be white (62.9%), located in the south region of the USA (40.1%), and be admitted to a teaching hospital (74.4%). When compared directly to weekday admissions, patients admitted over the weekend had higher odds of in-hospital mortality (odds ratio 1.07; confidence interval 95%, 1.02-1.12). There was no significant difference shown in the rate patients get surgical clipping versus endovascular coiling (p = 0.28) or the amount of time between admission to procedure for clipping (p = 0.473) or coiling (p = 0.255) on the weekend versus a weekday. CONCLUSION: Based on our findings, the likelihood of the in-hospital mortality was higher for patients admitted over the weekend. However, the characteristics of the study, primarily observational, prevent us arriving at an accurate conclusion about why this occurs; hence, we believe it is an important starting point to consider for future research.
