RESUMEN
INTRODUCTION: Age is often used as a predictor in determining outcomes in large vessel occlusions treated with mechanical thrombectomy. However, limited data exist for octo/nonagenarian outcomes compared to younger individuals in acute basilar artery occlusions treated with thrombectomy. METHODS: Patient data were obtained from the PC-SEARCH Thrombectomy Registry which consists of 444 acute basilar artery occlusions treated with mechanical thrombectomy. Individuals were dichotomized based on age (>80 and ≤80 years old). Primary outcome was defined as modified Rankin Scale of 0-3 at 90 days. Logistic and multivariate regression, as well as control-matched analysis, were performed. RESULTS: There were 373 and 71 patients in the younger and older cohorts, respectively. Gender, ethnicity, smoking status, atrial fibrillation, and coronary artery disease were noted to be significantly different between cohorts. At 90 days, 178 (47.7%) and 23 (32.4%) patients achieved primary outcome at 90 days (p = 0.02), however, after controlling for potentially confounding factors this association lost significance (OR 0.50 95% CI 0.24-1.05; p = 0.07). There were 84 patients included in the control matched analysis and demonstrated no significant differences on multivariate analysis between cohorts (OR 0.68 95% CI 0.25-1.84; p = 0.45). INTERPRETATION: Octa/nonagenarians presenting with an acute basilar artery occlusion treated with mechanical thrombectomy can achieve acceptable rates of favorable functional outcomes compared to younger individuals with similar baseline demographic and stroke characteristics.
RESUMEN
BACKGROUND AND OBJECTIVES: Intracranial atherosclerotic disease (ICAD) large vessel occlusion (LVO) is responsible for up to 30% of LVO. In this study, we aimed to determine the likelihood of favorable functional outcomes (modified Rankin Scale 0-3) in acute ICAD-LVO basilar occlusion compared with embolic basilar occlusion. METHODS: This is an analysis of the Posterior Circulation Ischemic Stroke Evaluation: Analyzing Radiographic and Intraprocedural Predictors for Mechanical Thrombectomy Registry in which patients with acute basilar artery occlusions from 8 comprehensive stroke centers were included from 2015 to 2021. Patients were dichotomized into with (ICAD-LVO) or without underlying ICAD (embolic). Descriptive statistics for each group and multivariate logistic analysis were performed on the primary outcome. RESULTS: Three hundred forty-six patients were included. There were 215 patients with embolic (62%) and 131 patients with ICAD-LVO (38%). Baseline demographics were equivalent between the 2 groups except for sex (male 47% vs 67%; P < .001), history of stroke (12% vs 25%; P = .002), and atrial fibrillation (31% vs 17%; P = .003). At 90 days, patients in the ICAD-LVO cohort were less likely to achieve favorable functional outcomes (odds ratio [OR] 0.41, 95% CI 0.22-0.72; P = .003) after adjusting for potentially confounding factors. In addition, ICAD-LVO strokes were less likely to achieve thrombolysis in cerebral infarction ≥2b (OR 0.29, 95% CI 0.14-0.57; P < .001). ICAD-LVO lesions were more likely to require stent placement (OR 14.94, 95% CI 4.91-45.49; P < .001). Subgroup analysis demonstrated favorable functional outcomes in patients who underwent stenting and angioplasty compared with failed recanalization cohort (OR 4.96, 95% CI 1.68-14.64; P < .004). CONCLUSION: Patients with acute basilar ICAD-LVO have higher morbidity and mortality compared with patients with embolic source. Lower rates of successful recanalization in the ICAD-LVO cohort support this finding. Our subgroup analysis demonstrates that stenting should be considered in patients with recanalization failure. Rates of symptomatic intracranial hemorrhage were similar between the ICAD-LVO and embolic cohorts.
RESUMEN
Cerebral venous sinus thrombosis (CVST) is a rare and potentially fatal condition. It is believed to be one of the rare complications of lumbar puncture (LP), however other causes and risk factors should be considered and ruled out. Diagnosis can be challenging after an LP as it can mimic low pressure or post dural puncture. We present a 23-year-old patient diagnosed with CVST following a diagnostic lumbar puncture, in the absence of other risk factors. The patient presented with a persistent headache that was initially attributed to low CSF pressure, as well as a transient episode of right hemi-body paresthesia. Neuroimaging including contrasted MRI with venography confirmed the diagnosis. The patient had negative hypercoagulable evaluation and was placed on anticoagulation on discharge. Our report highlights the importance of considering CVST in refractory headaches after LP and the value of neuroimaging when indicated.
RESUMEN
OBJECTIVE: There are limited data evaluating the optimum blood pressure (BP) goal post mechanical thrombectomy (MT) and its effect on outcomes of patients with large vessel occlusions (LVO). The objective of this study was to compare the efficacy and safety of intensive versus conventional BP control after reperfusion with MT via a systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS: We searched PubMed and Embase to obtain articles related to BP control post MT through September 2023. The primary outcome was functional independence (modified Rankin Scale [mRS] 0-2) at 3 months, while secondary outcomes included excellent outcome (mRS 0-1), symptomatic intracranial hemorrhage (sICH), and mortality. RESULTS: Four RCTs with 1,566 patients (762 randomized into intensive BP control vs. 806 randomized into conventional BP control) were included. Analysis showed that there was a lower likelihood of functional independence (mRS 0-2: odds ratio [OR]: 0.68, 95% confidence interval [CI] 0.51-0.91, p = 0.009) in the more intensive treatment group compared with the conventional treatment group. There was no statistically significant difference in achieving excellent outcome (mRS0-1: OR: 0.82, 95% CI: 0.63-1.07; p = 0.15), risk of sICH or mortality. INTERPRETATION: This systematic review and meta- analysis Indicates that in patients who achieved successful MT for acute ischemic stroke with LVO, intensive BP control was associated with a lower likelihood of functional independence at 3 months without significant difference in likelihood of achieving excellent outcome, sICH risk, or mortality.

Importance: Stroke-to-recanalization time is a strong predictor of outcomes in anterior circulation large-vessel occlusion (LVO). The authors aimed to evaluate functional outcomes in early (<6 h) vs. late (6-24 h) time windows for thrombectomy-treated basilar artery occlusions. Methods: Patients were derived from the Posterior Circulation Ischemic Stroke Evaluation: Analyzing Radiographic and Intra-procedural Predictors of Mechanical Thrombectomy (PC-SEARCH) Registry and retrospectively analyzed early and late basilar artery thrombectomy time windows cohorts. Patients were dichotomized based on the last known well and correlated to 90-day functional outcomes (mRS 0-3). A multiple logistic regression analysis was performed. Results: A total of 405 patients were included in this study: 216 and 189 patients in the early and late time windows, respectively. Baseline demographic, stroke, radiographic, and intraprocedural characteristics were similar between the groups. A total of 99 (46%) and 79 (42%) patients in the early and late time windows, respectively, achieved favorable functional outcomes at 90 days (p = 0.41), and multiple logistic regression analysis did not reveal differences between cohorts (OR: 0.74; 95% CI: 0.46-1.19; p = 0.22). Symptomatic hemorrhage (7% vs. 5%; p = 0.69) and neurological complications (8% vs. 9%; p = 0.83) were similar between the groups; however, hospital complications were more common in the early time window cohort (22% vs. 13%; p = 0.01). Conclusion: The early and late thrombectomy time windows can achieve similar rates of 90-day favorable functional outcomes. However, timely thrombectomy influences the likelihood of achieving excellent functional outcomes (mRS ≤ 2) within the early time window.
RESUMEN
OBJECTIVE: To assess the prognostic values of hyperdense sign on pretreatment non-contrast head CT scan for successful recanalization (mTICI ≥2b) and 90-day good functional outcome (mRs 0-2) in patients with acute ischemic stroke undergoing mechanical thrombectomy (MT). METHODS: Literature search on PubMed, EMBASE, and Cochrane databases from inception up to 1 November 2023 was conducted. Twelve studies which reported hyperdense sign, recanalization and clinical outcomes were included in qualitative synthesis and meta-analysis. RESULTS: Pooled analysis demonstrated a statistically significant association between successful recanalization and hyperdense sign-positive patients who underwent MT (odd ratios (OR) = 1.47, 95% confidence interval (CI) = 1.03-2.10, p = 0.04). No statistically significant association was demonstrated between presence of hyperdense sign and good functional outcome (OR = 1.04, 95% CI: 0.72-1.49, p = 0.85) or symptomatic intracranial hemorrhage sICH (OR: 1.80, 95% CI 0.72-4.47, p = 0.21). CONCLUSIONS: This meta-analysis demonstrated that pre-intervention hyperdense sign on CT imaging might be useful in prediction of successful recanalization after MT.
RESUMEN
INTRODUCTION: Recent randomized controlled trials demonstrated superiority of mechanical thrombectomy compared to medical therapy in acute basilar artery occlusions, however, little data is available to guide clinicians in functional prognosis and risk stratification. PATIENTS AND METHODS: Data from the retrospectively established PC-SEARCH Thrombectomy registry, which included patients with basilar artery occlusion from eight sites from January 2015 to December 2021, was interrogated. Outcomes were dichotomized into 90-day favorable (mRS ⩽ 3) and unfavorable (mRS > 3). Multivariate logistic regression analysis was performed with respect to the outcome groups and were adjusted for potential confounding baseline characteristics. RESULTS: Four-hundred-forty-four patients were included in this analysis. Mean age was 66 [SD 15], with 56% male, and comprised of 76% Caucasian. Patients presented with an initial median NIHSS of 18 and 199 patients (44.8%) achieved favorable 90-day functional outcomes. Independent predictors of favorable outcomes included younger age, pc-ASPECTS > 8 (OR 2.30 p < 0.001), and TICI ⩾ 2b (OR 7.56 p < 0.001). Unfavorable outcomes were associated with increasing number of passes (OR 1.29 p = 0.004) and sICH (OR 4.19 p = 0.015). IA-tPA was an independent risk factor for sICH (OR 7.15 p = 0.002) without improving favorable functional outcomes. CONCLUSION AND DISCUSSION: PC-ASPECTS > 8, successful recanalization (TICI ⩾ 2b), first-pass recanalization, and younger age are independent predictors of favorable 90-day functional outcome in thrombectomy treated patients with acute basilar artery occlusion. Conversely, sICH were independent predictors of unfavorable outcomes. IA-tPA and unsuccessful recanalization are independently associated with sICH.

We present a case report of a previously healthy 29 year old woman who developed thromboembolic events in rapid fashion after a recent orthopedic surgery. This case highlights the importance of understanding risk factors for clot formation even in those who had no prior events, the efficacy of novel aspiration techniques to remove emboli, and how rapid triaging of acute symptoms can lead to the best outcomes. She presented to the emergency department with shortness of breath and was found to have a large bilateral pulmonary embolus. She was given intravenous thrombolysis. Shortly after, she developed aphasia and right-sided weakness and was taken emergently for mechanical thrombectomy of a left middle cerebral artery occlusion. She was later found to have a patent foramen ovale and a highly mobile right atrial thrombus which was aspirated. Further evaluation revealed right lower extremity peroneal and popliteal deep venous thrombi. She was placed on anticoagulation, made a full clinical recovery, and was discharged home. Prompt recognition of symptoms, efficient in-hospital work flow, and a multidisciplinary approach led to an outstanding outcome in this young patient.
RESUMEN
BACKGROUND: Aspiration catheters (ASPs) and stentriever thrombectomy devices have comparable safety and efficacy in anterior circulation ischemic strokes. However, there is lack of high-quality comparative data in acute basilar artery occlusions. Our objective is to compare the outcomes and safety of ASPs and stentriever devices in acute basilar artery occlusions. METHODS: This is an analysis of the retrospectively established PC-SEARCH Thrombectomy (Posterior-Circulation Ischemic Stroke Evaluation: Analyzing Radiographic and Intraprocedural Predictors for Mechanical Thrombectomy) registry. Patients were dichotomized based on their first-line thrombectomy device (ASP and stentriever) and associated with their 90-day functional outcomes, intraprocedural metrics, and safety measures. Propensity analysis based on unequal baseline characteristics was performed. Consecutive patients with acute basilar artery occlusions who received mechanical thrombectomy were included from January 2015 to December 2021. Patients received either first-line contact aspiration or stentriever mechanical thrombectomy. Primary clinical and safety outcomes were 90-day functional independence measured by a modified Rankin Scale score of 0 to 3 and symptomatic intracranial hemorrhage, respectively. Secondary outcomes included puncture-recanalization times, first-pass recanalization rates, crossovers to other thrombectomy device, and neurological/hospital complications. RESULTS: Five hundred eighteen patients were included in the registry, and a total of 383 patients were included (mean [SD] age, 65.5 [15] years; 228 [59%] men) in this analysis. Of these, 219 patients were first-line ASP while 164 patients received first-line stentriever devices. Median premorbid modified Rankin Scale was zero and median presenting National Institutes of Health Stroke Scale was 17 (interquartile range, 8-26). The proportion of favorable functional outcome was similar between the 2 techniques before (47.3% versus 42.5%; odds ratio, 1.22 [95% CI, 0.78-1.89]; P=0.38) and after propensity matching (odds ratio, 1.46 [95% CI, 0.85-2.49]; P=0.17). In our propensity-matched cohorts, puncture-recanalization times (18 versus 52 minutes; P<0.01) favored first-line ASP; however, first-pass recanalization rates (43.5% versus 44.5%; P=0.90) were similar between groups. First-line ASP was associated with higher rates of crossover (22% versus 6%; P<0.01), whereas stentriever was associated with higher rates of symptomatic intracranial hemorrhage (9.8% versus 3.4%; P=0.04). CONCLUSIONS: First-line ASP and stentriever methods demonstrated similar functional outcome and recanalization rates. Stentriever methods were associated with higher rates of symptomatic intracranial hemorrhage, whereas ASPs were associated with higher rates of crossover to alternative technique in patients with acute basilar occlusions.

BACKGROUND: Headache with neurologic deficits and cerebrospinal fluid lymphocytosis, previously also termed pseudomigraine with temporary neurologic symptoms and lymphocytic pleocytosis, is a self-limiting syndrome characterized by moderate to severe headache associated with focal neurological deficits occurring in the context of lymphocytosis in the cerebrospinal fluid. As a consequence of its rarity, data regarding headache with neurologic deficits and cerebrospinal fluid lymphocytosis is sparse. Therefore, we conducted this review to analyze data related to 93 patients of headache with neurologic deficits and cerebrospinal fluid lymphocytosis, to characterize their demographics, clinical manifestations, investigations and treatment options. METHODS: We performed a systematic review of cases reported through PubMed and Google scholar database, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Keywords used were 'Headache with Neurologic Deficits and cerebrospinal fluid lymphocytosis', 'Headache with neurologic deficits and cerebrospinal fluid lymphocytosis syndrome'. The quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Tool. RESULTS: We analyzed a total of 93 cases of headache with neurologic deficits and cerebrospinal fluid lymphocytosis with a mean age of 28.8 years at onset. Seventy patients (75.2%) were adults, while 23 (24.7%) belonged to the pediatric age group. Comparing these groups, mean age at onset was 32.5 years and 14.3 years, respectively. The average duration of follow-up was 11.08 months. Thirty percent of patients experienced relapsing episodes of headache with neurologic deficits and cerebrospinal fluid lymphocytosis symptoms. The most common type of headache reported was unilateral severe throbbing episodic headache. Other associated symptoms included sensory deficit (60%) and motor deficits (54.8%). The least common symptoms were nystagmus and agraphia, which were reported in one patient each. Antiviral agents were a common treatment option in the acute phase (n = 23 patients [23.6%]), while Flunarizine was the most commonly used agent in the chronic setting (n = 3 patients [3.2%]). While most of the patients had normal brain magnetic resonance imaging, 20 patients had magnetic resonance imaging abnormalities, including (but not limited to) non-specific white matter lesions (eight patients) and meningeal enhancement (six patients). The most common electroencephalographic findings included diffuse and focal slowing. The mean cerebrospinal fluid opening-pressure was 240.5 mmH2O. Cerebrospinal fluid protein was elevated in 59 (63.4%) patients, with a mean value of 114 mg/dL. Two patients in our cohort were found to have cerebrospinal fluid oligoclonal bands. CONCLUSION: Headache with neurologic deficits and cerebrospinal fluid lymphocytosis tends to affect young individuals with a slight male predominance. Unilateral severe throbbing episodic headache with associated hemi-paresthesia and hemiparesis were the most common symptoms based on our review. Elevated cerebrospinal fluid opening-pressure can be seen in headache with neurologic deficits and cerebrospinal fluid lymphocytosis syndrome. Early recognition of the syndrome is paramount. Antivirals were found to be among the most widely used treatments in the acute setting. Magnetic resonance imaging of the brain is mostly normal. Diffuse and focal slowing were among the most common electroencephalographic findings. Cerebral flow abnormalities on perfusion scans are not uncommon in headache with neurologic deficits and cerebrospinal fluid lymphocytosis. Prospective studies with a larger sample size are needed to validate our findings and guide the clinical care of these patients.

INTRODUCTION: The modified Atkins diet (MAD), a less restrictive form of the ketogenic diet (KD), has gained popularity and is proposed to be an alternative to the traditional KD in the management of drug-resistant epilepsy (DRE). However, the evidence to support this hypothesis remains limited. In this meta-analysis, we aimed to evaluate the efficacy and tolerability of MAD compared to traditional KD in children with DRE. METHOD: We systematically searched multiple databases through March 2022 for all the studies that evaluated the clinical utility of MAD versus KD for DRE in a pediatric population. The primary outcome was the proportion of children who had seizure frequency reduction (SFR) > 50%. The secondary outcomes were SFR >90%, seizure freedom, and diet-related side effects. All measurements were taken 6 months after starting the regimens. Pooled risk ratio (RR) and corresponding 95% confidence intervals (CIs) were calculated and combined using random-effects model meta-analysis. RESULTS: Six studies, with 397 patients with DRE (201 followed MAD vs. 196 with KD), were included. There was a significant difference in the proportion of patients who attained SFR >50% favoring the traditional KD (RR: 0.63; 95% CI: 0.47-0.83; P = 0.001). However, there was no significant differences in SFR >90% (RR: 0.73; 95% CI: 0.49-1.10; P = 0.13) or the proportion of patients who had seizure freedom (RR: 0.83; 95% CI: 0.49-1.41; P = 0.49). Furthermore, both regimens had comparable safety profiles (RR: 1.00; 95% CI: 0.95-1.05; P = 0.96). CONCLUSIONS: Our meta-analysis demonstrated the superiority of traditional KD over MAD in achieving SFR > 50% at 6 months in pediatric patients with DRE. However, SFR > 90% and seizure freedom were comparable between KD and MAD at 6 months. The tolerability profile between the two regimens was similar as well. Large-scale RCTs are necessary to validate our findings.

Gradenigo syndrome (GS) was described primarily in the paediatric population, especially in the pre-antibiotic era. GS is rarely reported in the elderly population, especially in the post-antibiotic era. We present the rare case of a 67-year-old man who presented with an incomplete triad of symptoms (without abducens nerve palsy) of GS that failed medical therapy and was successfully treated with surgical intervention (mastoidectomy and petrous apicectomy). Physicians should be familiar with atypical presenting symptoms of GS as it can lead to life-threatening complications, especially in the elderly. GS cases resistant to medical therapy may require prompt appropriate imaging studies and surgical intervention. LEARNING POINTS: Gradenigo syndrome may present with an incomplete triad (without abducens nerve palsy), especially in the post-antibiotic era.Gradenigo syndrome can rarely affect immunocompromised elderly patients.Gradenigo syndrome cases resistant to medical therapy may require prompt appropriate imaging studies and surgical intervention (mastoidectomy and petrous apicectomy).
RESUMEN
Insulin resistance (IR) is a major contributor to the pathogenesis of nonalcoholic fatty liver disease (NAFLD). The triglyceride-glucose (TyG) index has recently gained popularity for the assessment of IR and NAFLD due to its ease of acquisition and calculation. Therefore, we conducted this systematic review and meta-analysis to summarize the existing studies in the literature and provide a quantitative assessment of the significance of the TyG index in predicting the incidence of NAFLD. A comprehensive literature search in PubMed, EMBASE, and Web of Science databases from inception until 25 March 2022 was conducted. Published observational studies that evaluated the association between TyG index and NAFLD among the adult population and reported the hazard ratio (HR) or odds ratio (OR) for this association after multivariate analysis were included. The random-effects model was used as the primary statistical analysis model in the estimation of pooled ORs and HRs with the corresponding confidence intervals (CIs). A total of 17 observational studies, including 121,975 participants, were included. For studies analyzing the TyG index as a categorical variable, both pooled OR (6.00, CI 4.12-8.74) and HR (1.70, CI 1.28-2.27) were significant for the association between TyG index and incident NAFLD. For studies analyzing the TyG index as a continuous variable, pooled OR (2.25, CI 1.66-3.04) showed similar results. Consistent results were obtained in subgroup analyses according to the study design, sample size, ethnicity, and diabetic status. In conclusion, our meta-analysis demonstrates that a higher TyG index is associated with higher odds of NAFLD. TyG index may serve as an independent predictive tool to screen patients at high risk of NAFLD in clinical practice, especially in primary care settings. Patients with a high TyG index should be referred for a liver ultrasound and start intense lifestyle modifications. However, further large-scale prospective cohort studies are necessary to validate our findings.
RESUMEN
The crystalloid fluid of choice in sepsis remains debatable. We aimed to perform a comprehensive meta-analysis to compare the effect of balanced crystalloids (BC) vs. normal saline (NS) in adults with sepsis. A systematic search of PubMed, EMBASE, and Web of Sciences databases through 22 January 2022, was performed for studies that compared BC vs. NS in adults with sepsis. Our outcomes included mortality and acute kidney injury (AKI), need for renal replacement therapy (RRT), and ICU length of stay (LOS). Pooled risk ratio (RR) and mean difference (MD) with the corresponding 95% confidence intervals (CIs) were obtained using a random-effect model. Fifteen studies involving 20,329 patients were included. Overall, BC showed a significant reduction in the overall mortality (RR 0.88, 95% CI 0.81-0.96), 28/30-day mortality (RR 0.87, 95% CI 0.79-0.95), and AKI (RR 0.85, 95% CI 0.77-0.93) but similar 90-day mortality (RR 0.96, 95% CI 0.90-1.03), need for RRT (RR 0.91, 95% CI 0.76-1.08), and ICU LOS (MD -0.25 days, 95% CI -3.44, 2.95), were observed between the two groups. However, subgroup analysis of randomized controlled trials (RCTs) showed no statistically significant differences in overall mortality (RR 0.92, 95% CI 0.82-1.02), AKI (RR 0.71, 95% CI 0.47-1.06), and need for RRT (RR 0.71, 95% CI 0.36-1.41). Our meta-analysis demonstrates that overall BC was associated with reduced mortality and AKI in sepsis compared to NS among patients with sepsis. However, subgroup analysis of RCTs showed no significant differences in both overall mortality and AKI between the groups. There was no significant difference in the need for RRT or ICU LOS between BC and NS. Pending further data, our study supports using BC over NS for fluid resuscitation in adults with sepsis. Further large-scale RCTs are necessary to validate our findings.
RESUMEN
OBJECTIVE: To describe the mortality difference between acute ischemic stroke (AIS) and non-AIS groups within COVID-19 patients. MATERIALS & METHODS: We included observational studies through September 2020 that categorized COVID-19 patients into two groups (with and without AIS). RESULTS: Eight studies with a total sample size of 19,399 COVID-19 patients were included. The pooled risk difference showed that patients with COVID-19 who developed AIS had significantly higher mortality than those without AIS by a risk difference of 24% (95% CI: 0.10-0.39; p = 0.001). In two studies, the COVID-19+AIS group had significantly higher lymphocytes, procalcitonin and creatinine levels. CONCLUSION: Developing AIS significantly adds to the mortality of COVID-19. Timely interventions to manage those patients are strongly recommended.
