Objective
The predictors of cranioplasty infection after decompressive craniectomy have not yet been fully characterized. The objective of the current study was to compare the long-term incidences of surgical site infection according to the graft material and cranioplasty timing after craniectomy, and to determine the associated factors of cranioplasty infection.Methods
A retrospective cohort study was conducted to assess graft infection in patients who underwent cranioplasty after decompressive craniectomy between 2001 and 2011 at a single-center. From a total of 197 eligible patients, 131 patients undergoing 134 cranioplasties were assessed for event-free survival according to graft material and cranioplasty timing after craniectomy. Kaplan-Meier survival analysis and Cox regression methods were employed, with cranioplasty infection identified as the primary outcome. Secondary outcomes were also evaluated, including autogenous bone resorption, epidural hematoma, subdural hematoma and brain contusion.Results
The median follow-up duration was 454 days (range 10 to 3900 days), during which 14 (10.7%) patients suffered cranioplasty infection. There was no significant difference between the two groups for event-free survival rate for cranioplasty infection with either a cryopreserved or artificial bone graft (p=0.074). Intergroup differences according to cranioplasty time after craniectomy were also not observed (p=0.083). Poor neurologic outcome at cranioplasty significantly affected the development of cranioplasty infection (hazard ratio 5.203, 95% CI 1.075 to 25.193, p=0.04).Conclusion
Neurologic status may influence cranioplasty infection after decompressive craniectomy. A further prospective study about predictors of cranioplasty infection including graft material and cranioplasty timing is necessary. 相似文献2.

Background and Purpose
Cerebral venous thrombosis (CVT) is a special cerebrovascular disease that accounts for around 0.5%–1.0% of all strokes and often occurs in younger adults. Intracranial hypertension is the most frequent symptom of acute CVT due to venous occlusion. This study aimed to ascertain the risk factors for intracranial hypertension after CVT and to investigate whether intracranial hypertension at diagnosis may affect patient outcomes.Methods
We performed a retrospective cohort analysis of all patients treated for acute/subacute CVT at our department between 2018 and 2021. Logistic regression analysis was performed to identify potential risk factors associated with intracranial hypertension after CVT and clinical outcomes at the 6-month follow-up.Results
A total of 293 acute/subacute CVT survivors were eligible for inclusion, with 245 patients (83.60%) experiencing concomitant intracranial hypertension at diagnosis. In the multivariable regression analysis, hereditary thrombophilia (OR 2.210, 95% CI 1.148–4.254, p = 0.018) and thrombosis location of superior sagittal sinus (SSS) and right lateral sinus (LS) (OR 4.115, 95% CI 1.880–9.010, p = 0.000) were independently associated with intracranial hypertension. 83.67% of patients with intracranial hypertension after CVT had favorable functional outcomes (mRS score, 0–2), whereas they more often had residual visual impairment (15.51% vs. 4.17%, p = 0.036) at follow-up. The risk factors for residual visual impairment were papilledema (OR 2.971, 95% CI 1.231–7.170, p = 0.015) and visual disturbances at diagnosis (OR 2.869, 95% CI 1.123–7.327, p = 0.028), thrombosis location (SSS and right LS [OR 10.811, 95% CI 4.208–27.773, p = 0.000]; SSS and left LS [OR 3.139, 95% CI 1.409–6.995, p = 0.005]), and CVT recurrence (OR 4.763, 95% CI 1.556–14.584, p = 0.006).Conclusions
Intracranial hypertension is the most common clinical symptom of acute CVT. At follow-up, patients with intracranial hypertension after CVT were more prone to develop residual visual impairment. 相似文献3.
Objective
The purposes of this study are to investigate the factors that may be related to ventriculoperitoneal (VP) shunt in patients with cerebellar hematoma and the effect of severe fourth ventricular hemorrhage, causing obstructive hydrocephalus on subsequent VP shunt performance.Methods
This study included 31 patients with spontaneous cerebellar hematoma and concomitant fourth ventricular hemorrhage, who did not undergo a surgical evacuation of hematoma. We divided this population into two groups; the VP shunt group, and the non-VP shunt group. The demographic data, radiologic findings, and clinical factors were compared in each group. The location of the hematoma (whether occupying the cerebellar hemisphere or the vermis) and the degree of the fourth ventricular obstruction were graded respectively. The intraventricular hemorrhage (IVH) score was used to assess the IVH severity.Results
Ten out of 31 patients underwent VP shunt operations. The midline location of cerebellar hematoma, the grade of fourth ventricle obstruction, and IVH severity were significantly correlated with that of VP shunt operation (p=0.015, p=0.013, p=0.028). The significant variables into a logistic regression multivariate model resulted in statistical significance for the location of cerebellar hemorrhage [p=0.05; odds ratio (OR), 8.18; 95% confidence interval (CI), 1.00 to 67.0], the grade of fourth ventricle obstruction (p=0.044; OR, 19.26; 95% CI, 1.07 to 346.6).Conclusion
The location of the cerebellar hematoma on CT scans and the degree of fourth ventricle obstruction by IVH were useful signs for the selection of VP shunt operation in patients with spontaneous cerebellar hematoma and concomitant acute hydrocephalus. 相似文献4.
Background
The relationship between the age at menarche (AAM) and the risk of intracerebral hemorrhage (ICH) and ischemic stroke (IS) is still up for debate. The purpose of this study was to investigate potential causal connections between them.Methods
Genome-wide association analysis (GWAS) of AAM conducted by the MRC-IEU consortium was utilized for association analyses of ICH and IS by two-sample Mendelian randomization (MR) study. AAM data of the within-family GWAS consortium were used as replication phase data to verify the causal relationship between each other. Inverse variance weighting (IVW) method was the primary method used in this MR study. For additional proof, the weighted median estimation, MR-Egger regression, MR-PRESSO test, and MR-Robust Adjusted Profile Score evaluation were performed. The Cochran's Q test and the MR-PRESSO global test were used, respectively, to examine the sensitivity and pleiotropy. Random effects meta-analysis was utilized to analyze the causal data from the two consortiums to further explore the causality between AAM and ICH, IS.Results
We found that the AAM was causally linked with the risk of ICH (OR = 0.48, 95% CI: 0.28–0.80, p = 0.006). On the contrary, the causal effect from AAM to IS (OR = 0.98, 95% CI: 0.91–1.06, p = 0.64) has not been confirmed. For all subtypes of ICH, we found that nonlobar intracerebral hemorrhage (NLICH, OR = 0.41, 95% CI: 0.23–0.75, p = 0.004) but not lobar intracerebral hemorrhage (LICH, OR = 0.65, 95% CI: 0.34–1.24, p = 0.19) was associated with AAM without surprise. Similarly, we used the within-family GWAS consortium data to explore causality and found that AAM may reduce the risk of ICH (OR = 0.78, 95% CI: 0.72–0.86, p = 9.5 × 10−8) and NLICH (OR = 0.68, 95% CI: 0.61–0.75, p = 3.4 × 10−13) by IVW methods, but is not related to IS (OR = 0.97, 95% CI: 0.93–1.02, p = 0.26). These findings are further supported by the meta-analysis. Both Cochran's Q test and the MR-PRESSO global test failed to detect the presence of sensitivity.Conclusion
AAM and ICH, particularly NLICH, are causally related, but not LICH, IS, or its subtypes in European population. 相似文献5.

Background and Purpose
Remote ischemic conditioning (RIC) is a remote, transient, and noninvasive procedure providing temporary ischemia and reperfusion. However, there is no comprehensive literature investigating the efficacy and safety of RIC for the treatment of acute ischemic stroke. In the present study, we performed a comprehensive meta-analysis of the available studies.Methods
MEDLINE, Embase, the Cochrane Library database (CENTRAL), and ClinicalTrials.gov were searched before Sep 7, 2022. The data were analyzed using Review Manager 5.4.1 software, Stata version 16.0 software, and R 4.2.0 software. Odds ratio (OR), mean difference (MD), and corresponding 95% CIs were pooled using fixed-effects meta-analysis.Results
We pooled 6392 patients from 17 randomized controlled trials. Chronic RIC could reduce the recurrence of ischemic stroke at the endpoints (OR 0.67, 95% CI [0.51, 0.87]). RIC could also improve the prognosis of patients at 90 days as assessed by mRS score (mRS 0–1: OR 1.29, 95% CI [1.09, 1.52]; mRS 0–2: OR 1.22, 95% CI [1.01, 1.48]) and at the endpoints assessed by NIHSS score (MD −0.99, 95% CI [−1.45, −0.53]). RIC would not cause additional adverse events such as death (p = 0.72), intracerebral hemorrhage events (p = 0.69), pneumonia (p = 0.75), and TIA (p = 0.24) but would inevitably cause RIC-related adverse events (OR 26.79, 95% CI [12.08, 59.38]).Conclusions
RIC could reduce the stroke recurrence and improve patients' prognosis. Intervention on bilateral upper limbs, 5 cycles, and a length of 50 min in each intervention might be an optimal protocol for RIC at present. RIC could be an effective therapy for patients not eligible for reperfusion therapy. RIC would not cause other adverse events except for relatively benign RIC-related adverse events. 相似文献6.

Aims
To investigate the causal role of serum magnesium and calcium in epilepsy or any of its subtypes through Mendelian randomization (MR) approach.Methods
Single nucleotide polymorphisms (SNPs) associated with serum magnesium and calcium were used as the instrumental variables. MR analyses were performed using the summary-level data for epilepsy extracted from International League Against Epilepsy Consortium (15,212 cases and 29,677 controls) to obtain the causal estimates. The analyses were replicated using FinnGen data (7224 epilepsy cases and 208,845 controls), and a meta-analysis was then conducted.Results
The result of combined analyses showed that higher serum magnesium concentrations was associated with a reduced risk of overall epilepsy (odds ratios [OR] = 0.28, 95% confidence interval [CI], 0.12–0.62, p = 0.002). In ILAE, higher serum magnesium was suggestively associated with reduced risks of focal epilepsy (OR = 0.25, 95% CI 0.10–0.62, p = 0.003). However, the results cannot be repeated in sensitivity analyses. As for serum calcium, the results did not reach statistical significance with overall epilepsy (OR = 0.60, 95% CI, 0.31–1.17, p = 0.134). However, genetically predicted serum calcium concentrations showed an inverse association with risk of generalized epilepsy (OR = 0.35, 95% CI, 0.17–0.74, p = 0.006).Conclusion
The current MR analysis did not support a causal relationship between serum magnesium and epilepsy, but showed a causally negative association between genetically determined serum calcium and generalized epilepsy. 相似文献7.

Background and purpose
Incidence of ischemic stroke in young adults has been steadily increasing over the past 20 years. One hypothesis to explain this phenomenon is the increase in the use of illicit drugs, including cannabis. However, the mechanisms and the clinical presentation of ischemic stroke associated with cannabis use are unclear. The objective of this study was to describe the phenotype of ischemic stroke in cannabis users compared to nonusers among a population of young adults with a first-ever ischemic stroke.Methods
Patients aged 18–54 years consecutively hospitalized in a university department of neurology for a first-ever ischemic stroke from January 2017 to July 2021 were included. Drug use over the past year was assessed by a semistructured interview, and the stroke phenotype was described using the ASCOD classification.Results
A total of 691 patients, including 78 of 691 (11.3%) cannabis users, were included. Cannabis use was independently associated with potential A1 (odds ratio [OR] = 3.30, 95% confidence interval [CI] = 1.45–7.5, p = 0.004) and uncertain A2 (OR = 13.1, 95% CI = 2.89–59.4, p < 0.001) atherosclerotic cause of stroke after adjustment for vascular risk factors including tobacco and other drug use. Moreover, the association of atherosclerosis and cannabis use was significant for frequent (OR = 3.13, 95% CI = 1.07–8.6, p = 0.030) and daily cannabis use (OR = 4.43, 95% CI = 1.40–13.4, p = 0.008), but not for occasional use.Conclusions
We found a significant, independent, and graded association of cannabis use with the atherosclerotic stroke phenotype. 相似文献8.

Aims
Although intravenous thrombolysis (IVT) has not shown confirmative effects on the outcomes of patients receiving successful thrombectomy, it might influence the outcomes of a subset of these patients. This study aims to evaluate whether the effects of IVT depend on final reperfusion grade in patients with successful thrombectomy.Methods
This is a single-center, retrospective analysis of patients with an acute anterior circulation large-vessel occlusion and a successful thrombectomy between January 2020 and June 2022. Final reperfusion grade was evaluated by the modified Thrombolysis in Cerebral Infarction (mTICI) score, which was dichotomized into incomplete (mTICI 2b) and complete (mTICI 3) reperfusion. The primary outcome was functional independence (90-day modified Rankin Scale score 0–2). Safety outcomes were 24-h symptomatic intracranial hemorrhage and 90-day all-cause mortality. Multivariable logistic regression analyses were used to assess the interactions between IVT treatment and final reperfusion grade on outcomes.Results
When comparing all 167 patients enrolled in the study, IVT did not influence the extent of functional independence (adjusted OR: 1.38; 95% CI: 0.65–2.95; p = 0.397). The effect of IVT on functional independence depended on final reperfusion grade (p = 0.016). IVT benefited patients with incomplete reperfusion (adjusted OR: 3.70; 95% CI 1.21–11.30; p = 0.022), but not those with complete reperfusion (adjusted OR: 0.48, 95% CI: 0.14–1.59; p = 0.229). IVT was not associated with 24-h symptomatic intracerebral hemorrhage (p = 0.190) or 90-day all-cause mortality (p = 0.545).Conclusions
The effect of IVT on functional independence depended on final reperfusion grade in patients with successful thrombectomy. IVT appeared to benefit patients with incomplete reperfusion, but not those with complete reperfusion. Because reperfusion grade cannot be determined prior to endovascular treatment, this study argues against withholding IVT in IVT-eligible patients. 相似文献9.

Objective
This study was conducted to clarify the association factors and clinical significance of the CT angiography (CTA) spot sign and hematoma growth in Korean patients with acute intracerebral hemorrhage (ICH).Methods
We retrospectively collected the data of 287 consecutive patients presenting with acute ICH who arrived within 12 hours of ictus. Baseline clinical and radiological characteristics as well as the mortality rate within one month were assessed. A binary logistic regression was conducted to obtain association factors for the CTA spot sign and hematoma growth.Results
We identified a CTA spot sign in 40 patients (13.9%) and hematoma growth in 78 patients (27.2%). An elapsed time to CT scan of less than 3 hours (OR, 5.14; 95% CI, 1.76-15.02; p=0.003) was associated with the spot sign. A CTA spot sign (OR, 5.70; 95% CI, 2.70-12.01; p<0.001), elevated alanine transaminase (GPT) level >40 IU (OR, 2.01; 95% CI, 1.01-4.01; p=0.047), and an international normalized ratio ≥1.8 or warfarin medication (OR, 5.64; 95% CI, 1.29-24.57; p=0.021) were independent predictors for hematoma growth. Antiplatelet agent medication (OR, 4.92; 95% CI, 1.31-18.50; p=0.019) was significantly associated with hematoma growth within 6 hours of ictus.Conclusion
As previous other populations, CTA spot sign was a strong predictor for hematoma growth especially in hyper-acute stage of ICH in Korea. Antithrombotics medication might also be associated with hyper-acute hematoma growth. In our population, elevated GPT was newly identified as a predictor for hematoma growth and its effect for hematoma growth is necessary to be confirmed through a further research. 相似文献10.
Introduction
Ventricular access devices (VAD) and ventriculosubgaleal shunts (VSGS) are currently both used as temporising devices to affect CSF drainage in neonatal posthaemorrhagic hydrocephalus (PHH), without clear evidence of superiority of either procedure. In this systematic review and meta-analysis, we compared the VSGS and VAD regarding complication rates, ventriculoperitoneal shunt conversion and infection rates, and mortality and long-term disability.Methods
The review was registered with the PROSPERO international prospective register of systematic reviews (registration number CRD42015019750) and was conducted in accordance with PRISMA guidelines.Results and conclusions
The literature search of five databases identified 338 publications, of which 5 met the inclusion criteria. All were retrospective cohort studies (evidence class 3b and 4). A significantly lower proportion of patients with a VSGS required CSF tapping compared to patients with a VAD (log OR ?4.43, 95 % CI ?6.14 to ?2.72). No other significant differences between the VAD and VSGS were identified in their rates of infection (log OR 0.03, 95 % CI ?0.77 to 0.84), obstruction (log OR 1.25, 95 % CI ?0.21 to 2.71), ventriculoperitoneal shunt dependence (log OR ?0.06, 95 % CI ?0.93 to 0.82), subsequent shunt infection (log OR 0.23, 95 % CI ?0.61 to 1.06), mortality (log OR 0.37, 95 % CI ?0.95 to 1.70) or long-term disability (p = 0.9). In all studies, there was a lack of standardised criteria, variations between surgeons in heterogeneous cohorts of limited sample size and a lack of neurodevelopmental follow-up. This affirms the importance of an ongoing multicentre, prospective pilot study comparing these two temporising procedures to enable a more robust comparison.11.

Background and purpose
Although two doses of COVID-19 vaccine elicited a protective humoral response in most persons with multiple sclerosis (pwMS), a significant group of them treated with immunosuppressive disease-modifying therapies (DMTs) showed less efficient responses.Methods
This prospective multicenter observational study evaluates differences in immune response after a third vaccine dose in pwMS.Results
Four hundred seventy-three pwMS were analyzed. Compared to untreated patients, there was a 50-fold decrease (95% confidence interval [CI] = 14.3–100.0, p < 0.001) in serum SARS-CoV-2 antibody levels in those on rituximab, a 20-fold decrease (95% CI = 8.3–50.0, p < 0.001) in those on ocrelizumab, and a 2.3-fold decrease (95% CI = 1.2–4.6, p = 0.015) in those on fingolimod. As compared to the antibody levels after the second vaccine dose, patients on the anti-CD20 drugs rituximab and ocrelizumab showed a 2.3-fold lower gain (95% CI = 1.4–3.8, p = 0.001), whereas those on fingolimod showed a 1.7-fold higher gain (95% CI = 1.1–2.7, p = 0.012), compared to patients treated with other DMTs.Conclusions
All pwMS increased their serum SARS-CoV-2 antibody levels after the third vaccine dose. The mean antibody values of patients treated with ocrelizumab/rituximab remained well below the empirical "protective threshold" for risk of infection identified in the CovaXiMS study (>659 binding antibody units/mL), whereas for patients treated with fingolimod this value was significantly closer to the cutoff. 相似文献12.

Objective
Infection and bone resorption are major complications of cranioplasty and have been well recognized. However, there are few clinical series describing the epidural fluid collection (EFC) as complication of cranioplasty. This study was planned to identify the predictive factors and fate of EFC after cranioplasty.Methods
We reviewed retrospectively the demographic, clinical, and radiographic data in 59 patients who underwent a first cranioplsty following decompressive craniectomy during a period of 6 years, from January 2004 to December 2009. We compared demographic, clinical, and radiographic factors between EFC group and no EFC group. The predictive factors associated with the development of EFC were assessed by logistic regression analysis.Results
Overall, 22 of 59 patients (37.3%) suffered from EFC following cranioplasty. EFC had disappeared (n=6, 31.8%) or regressed (n=6, 31.8%) over time on follow up brain computed tomographic (CT) scans. However, 5 patients (22.7%) required reoperation due to symptomatic and persistent EFC. Predictive factors for EFC were male [odds ratio (OR), 5.48; 95% CI, 1.26-23.79], air bubbles in the epidural space (OR, 12.52; 95% CI, 2.26-69.28), and dural calcification on postoperative brain CT scan (OR, 4.21; 95% CI, 1.12-15.84).Conclusion
The most of EFCs could be treated by conservative therapy. Air bubble in the epidural space and dural calcification are proposed to be the predictive factors in the formation of EFC after cranioplasty. 相似文献13.

Objective
This study aimed to investigate the relationships of heart rate variability (HRV) with the presence, severity, and individual neuroimaging markers of cerebral small vessel disease (CSVD).Method
A total of 4676 participants from the Third China National Stroke Registry (CNSR-III) study were included in this cross-sectional analysis. CSVD and its markers, including white matter hyperintensity (WMH), lacunes, enlarged perivascular spaces (EPVS), cerebral microbleeds (CMBs), and brain atrophy (BA), were evaluated. Two common HRV parameters, including the square root of the mean of the sum of the squares of differences between adjacent N–N intervals (RMSSD) and the standard deviation of all N–N intervals (SDNN), were used to evaluate the function of the autonomic nervous system (ANS). Binary or ordinal logistic regression analyses were performed to investigate the association between HRV and CSVD. In addition, two-sample mendelian randomization (MR) analyses were performed to investigate the causality of HRV with CSVD.Results
RMSSD was significantly associated with total burden of CSVD (Wardlaw's scale, common odds ratio [cOR] 0.80, 95% confidence interval [CI] 0.67–0.96, p = 0.02; Rothwell's scale, cOR 0.75, 95% CI 0.60–0.93, p = 0.008) and the presence of CSVD (Rothwell, OR 0.75, 95% CI 0.60–0.93, p = 0.008). However, no significant associations between SDNN and the presence or total burden of CSVD were observed. Moreover, RMSSD was related to WMH burden (OR 0.80, 95% CI 0.66–0.96, p = 0.02), modified WMH burden (cOR 0.82, 95% CI 0.69–0.97, p = 0.02), and Deep-WMH (OR 0.75, 95% CI 0.62–0.91, p = 0.003), while SDNN was related to Deep-WMH (OR 0.80, 95% CI 0.66–0.96, p = 0.02) and BA (cOR 0.80, 95% CI 0.68–0.95, p = 0.009). Furthermore, adding HRV to the conventional model based on vascualr risk factors enhanced the predictive performance for CSVD, as validated by the integrated discrimination index (p < 0.05). In addition, no causality between HRV and CSVD was observed in two-sample MR analyses.Conclusion
Decreased HRV may be a potential risk factor of CSVD, implying the possible role of the ANS in the pathogenesis of CSVD. 相似文献14.
Background and Purpose: Symptomatic carotid stenosis (sCS), a common cause of transient ischemic attack (TIA), is correlated with higher stroke risk. We investigated the frequency and associated factors of sCS in patients with TIA and the association between sCS and stroke risk following TIA. Methods: Over a three-year period (2011–2013), 861 consecutive patients with TIA, who were admitted to the Department of Neurology at the University of Lübeck, Germany, were included in a monocenter study and prospectively evaluated. Diagnosis of TIA was in accordance with the tissue-based definition (transient neurological symptoms without evidence of infarction by brain imaging). Results: Of 827 patients (mean age, 70 ± 13.2 years; 49.7% women), 64 patients (7.7%; 95% confidence interval [CI], 5.9%–9.7%) exhibited sCS and 3 patients (0.3%) showed an occlusion of the corresponding internal carotid artery. Logistic regression revealed that sCS was associated with male sex (odds ratio [OR], 2.7; 95% CI, 1.2–3.6; p = 0.012), amaurosis fugax (OR, 8.1; 95% CI, 3.4–19–4; p < 0.001), unilateral weakness (OR, 3.4; 95% CI, 1.9–6.1; p < 0.001), symptom duration less than 1 h (OR, 2.0; 95% CI, 1.1–3.4; p = 0.019) and previous stroke (OR, 2.7; 95% CI, 1.5–4.7; p = 0.001). During hospitalization (mean, 6.6 days), five patients (0.6%; 95% CI, 0.1%–1.2%) suffered from stroke. The stroke risk was higher in patients with sCS than in those without sCS (6.3% vs. 0.1%; p < 0.001), whereas the recurrent TIA risk (2.6%) did not differ between the groups (4.7% vs. 2.5%; p = 0.29). Conclusion: SCS appears to be associated with a higher risk of stroke in patients with TIA defined according to the tissue-based definition. 相似文献

Objective
The evaluation to determine candidacy and treatment for epilepsy surgery in persons with drug-resistant epilepsy (DRE) is not uniform. Many non-invasive and invasive tests are available to ascertain an appropriate treatment strategy. This study examines expert response to clinical vignettes of magnetic resonance imaging (MRI)–positive lesional focal cortical dysplasia in both temporal and extratemporal epilepsy to identify associations in evaluations and treatment choice.Methods
We analyzed annual report data and a supplemental epilepsy practice survey reported in 2020 from 206 adult and 136 pediatric epilepsy center directors in the United States. Non-invasive and invasive testing and surgical treatment strategies were compiled for the two scenarios. We used chi-square tests to compare testing utilization between the two scenarios. Multivariable logistic regression modeling was performed to assess associations between variables.Results
The supplemental survey response rate was 100% with 342 responses included in the analyses. Differing testing and treatment approaches were noted between the temporal and extratemporal scenarios such as chronic invasive monitoring selected in 60% of the temporal scenario versus 93% of the extratemporal scenario. Open resection was the most common treatment choice; however, overall treatment choices varied significantly (p < .001). Associations between non-invasive testing, invasive testing, and treatment choices were present in both scenarios. For example, in the temporal scenario stereo-electroencephalography (SEEG) was more commonly associated with fluorodeoxyglucose–positron emission tomography (FDG-PET) (odds ratio [OR] 1.85; 95% confidence interval [CI] 1.06–3.29; p = .033), magnetoencephalography (MEG) (OR 2.90; 95% CI 1.60–5.28; p = <.001), high density (HD) EEG (OR 2.80; 95% CI 1.27–6.24; p = .011), functional MRI (fMRI) (OR 2.17; 95% CI 1.19–4.10; p = .014), and Wada (OR 2.16; 95% CI 1.28–3.66; p = .004). In the extratemporal scenario, choosing SEEG was associated with increased odds of neuromodulation over open resection (OR 3.13; 95% CI 1.24–7.89; p = .016).Significance
In clinical vignettes of temporal and extratemporal lesional DRE, epilepsy center directors displayed varying patterns of non-invasive testing, invasive testing, and treatment choices. Differences in practice underscore the need for comparative trials for the surgical management of DRE. 相似文献16.

Background and purpose
Longitudinally extensive transverse myelitis (LETM) associated with aquaporin-4 autoantibodies (AQP4-IgG) can cause severe disability. Early diagnosis and prompt treatment are critical to prevent relapses. A novel score is described based on clinical and neuroimaging characteristics that predicts AQP4-IgG positivity in patients with LETM.Methods
Patients were enrolled both retrospectively and prospectively from multiple Italian centers. Clinical and neuroimaging characteristics of AQP4-IgG positive and negative patients were compared through univariate and multivariate analysis.Results
Sixty-six patients were included. Twenty-seven (41%) were AQP4-IgG positive and median age at onset was 45.5 years (range 19–81, interquartile range 24). Female sex (odds ratio [OR] 17.9, 95% confidence interval [CI] 2.6–381.9; p = 0.014), tonic spasms (OR 45.6, 95% CI 3.1–2197; p = 0.017) and lesion hypointensity on T1-weighted images (OR 52.9, 95% CI 6.8–1375; p = 0.002) were independently associated with AQP4-IgG positivity. The AQP4-IgG positivity in myelitis (AIM) score predicted AQP4-IgG positivity with 85% sensitivity and 95% specificity. Positive and negative likelihood ratios were 16.6 and 0.2 respectively. The inter-rater and intra-rater agreement in the score application were both excellent.Conclusions
The AIM score predicts AQP4-IgG positivity with good sensitivity and specificity in patients with a first episode of LETM. The score may assist clinicians in early diagnosis and treatment of AQP4-IgG positive LETM. 相似文献17.

Aims
To investigate the predicted factors influencing the outcomes in acute ischemic stroke (AIS) patients who received tirofiban after endovascular treatment (EVT) and the optimal administration of tirofiban.Methods
In this retrospective study, AIS patients who received EVT followed by tirofiban between January 2017 and October 2021 were enrolled. The dose and duration of tirofiban were adjusted by trained clinicians according to the patient's clinical status. A reduction of at least four points on the National Institutes of Health Stroke Scale (NIHSS) after tirofiban compared with that before tirofiban was defined as an effective response. A modified ranking scale (mRS) of 0–2 was defined as a favorable outcome at a 90-day follow-up.Results
A total of 260 consecutive patients were enrolled, and 36.5% of patients achieved a favorable outcome. The modified thrombolysis in cerebral infarction (mTICI) 2b-3 occurred in 93.5% of patients. Symptomatic intracerebral hemorrhage (sICH) occurred in 6.2% of patients, and the mortality at 90-day follow-up was 16.9%. Duration of tirofiban >24 h (adjusted OR: 2.545; 95% CI: 1.008–6.423; p = 0.048) and effective response to tirofiban (adjusted OR: 25.562; 95% CI: 9.794–66.715; p < 0.001) were related to the favorable outcome (mRS 0–2). Higher NIHSS (adjusted OR: 0.855; 95% CI: 0.809–0.904; p < 0.001) and glucose level on admission (adjusted OR: 0.843; 95% CI: 0.731–0.971; p = 0.018) were predictive for the unfavorable outcome (mRS 3–6).Conclusions
An effective response to tirofiban is an independent factor in predicting the long-term efficacy outcome, and extending the duration of tirofiban is beneficial for neurological improvement. 相似文献18.

Background
Infections after intracerebral hemorrhage (ICH) may be associated with worse outcomes. We aimed to evaluate the association between nosocomial infections (>48 h) and outcomes of ICH at a population level.Methods
We identified patients with ICH using ICD-9-CM codes in the 2002–2011 Nationwide Inpatient Sample. Demographics, comorbidities, surgical procedures, and hospital characteristics were compared between patients with and without concomitant nosocomial infections. Primary outcomes were in-hospital mortality and home discharge. Secondary outcome was permanent cerebrospinal shunt placement. Logistic regression analyses were used to analyze the association between infections and outcomes.Results
Among 509,516 ICH patients, infections occurred in 117,636 (23.1 %). Rates of infections gradually increased from 18.7 % in 2002–2003 to 24.1 % in 2010–2011. Pneumonia was the most common nosocomial infection (15.4 %) followed by urinary tract infection (UTI) (7.9 %). Patients with infections were older (p < 0.001), predominantly female (56.9 % vs. 47.9 %, p < 0.001), and more often black (15.0 % vs. 13.4 %, p < 0.001). Nosocomial infection was associated with longer hospital stay (11 vs. 5 days, p < 0.001) and a more than twofold higher cost of care (p < 0.001). In the adjusted regression analysis, patients with infection had higher odds of mortality [odds ratio (OR) 2.11, 95 % CI 2.08–2.14] and cerebrospinal shunt placement (OR 2.19, 95 % CI 2.06–2.33) and lower odds of home discharge (OR 0.49, 95 % CI 0.47–0.51). Similar results were observed in subgroup analyses of individual infections.Conclusions
In a nationally representative cohort of ICH patients, nosocomial infection was associated with worse outcomes and greater resource utilization.19.

Several psychological comorbidities are thought to be associated with excessive Internet use. This study aimed to assess the relation between excessive Internet use and self-esteem among Internet users in Egypt. In this cross-sectional study, a Google form questionnaire, composed of three sections, was used to assess participants’ sociodemographic characteristics and daily Internet use. Self-esteem was evaluated using the Arabic version of the Rosenberg Self-Esteem Scale. Only people ≥18?years who reported having a stable Internet access and were residing in Egypt were included. Our results indicated that 25.3% of the 407 participants reported excessive Internet use (>4?h/day) and 29.5% had low self-esteem. Logistic regression showed that age ≤ 25?years and being unmarried were risk factors of excessive Internet use; (OR 2.85, 95% CI: 1.44–5.66; p value = 0.003) and (OR 2.64, 95% CI: 1.20–5.80; p value = 0.015), respectively. Low self-esteem associated with excessive Internet use by the univariate analysis (OR 1.68, 95% CI: 1.05–2.69; p value = 0.022), yet after adjustment for other covariates, the association attenuated (OR 1.44, 95% CI: 0.86–2.41; p value = 0.162). In participants ≤ 25?years, the association between self-esteem and excessive Internet use remained significant after adjustment for the covariates (Before: OR 2.04, 95% CI: 1.08–3.85; p value = 0.020 vs. After: OR 2.12, 95% CI: 1.11–4.08; p value = 0.015). In conclusion, excessive Internet use is a common finding among Internet users in Egypt. Young and unmarried people are more susceptible to use the Internet excessively. Low self-esteem in young people is associated with excessive Internet use. 相似文献
