High NLR was associated with poor outcome in critically ill patients with ARDS. The PLR therefore appears to be a prognostic biomarker of outcomes in critically ill patients with ARDS. Further investigation is required to validate this relationship with data collected prospectively.

Background:In recent years, neuroendoscopy has been used as a method for treating intracerebral hemorrhages (ICHs). However, the efficacy and safety of neuroendoscopic surgery is still controversial compared with that of craniotomy. Our aim was to compare the outcomes of neuroendoscopic surgery and craniotomy in patients with supratentorial hypertensive ICH using a meta-analysis.Methods:We searched on PubMed, EMBASE, and Cochrane Central Register of Controlled Trials to identify relevant studies in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Quality of eligible studies was evaluated and the related data were extracted by 2 reviewers independently. This study assessed clinical outcomes, evacuation rates, complications, operation time, and hospital stay for patients who underwent neuroendoscopic surgery (NE group) or craniotomy (craniotomy group).Results:Meta-analysis included 1327 subjects from verified studies of acceptable quality. There was no significant heterogeneity between the included studies based on clinical outcomes. Compared with craniotomy, neuroendoscopic surgery significantly improved clinical outcomes in both randomized controlled studies (RCTs) group (relative risk: 0.62; 95% confidence interval [CI], 0.47–0.81, P < .001) and non-RCTs group (relative risk: 0.84; 95% CI: 0.75–0.95, P = .005); decreased the rate of death (relative risk: 0.53; 95% CI, 0.37–0.76, P < .001) in non-RCTs group but not in RCTs group (relative risk: 0.58; 95% CI, 0.26–1.29, P = .18); increased evacuation rates in non-RCTs group (standard mean differences: 0.75; 95% CI, 0.24–1.26, P = .004) and had a tendency of higher evacuation rates in RCTs group (standard mean differences: 1.34; 95% CI, 0.01–2.68, P = .05); reduced the total risk of complications in non-RCTs group (relative risk: 0.45; 95% CI, 0.25–0.83, P = .01) and RCTs group (relative risk: 0.37; 95% CI, 0.28–0.49, P < .001); reduced the operation time in non-RCTs group (standard mean differences: 3.26; 95% CI: 1.20–5.33, P < .001) and RCTs group (standard mean differences: 4.37; 95% CI: 3.32–5.41, P < .001).Conclusions:Our results suggested that the NE group showed better clinical outcomes than the craniotomy group for patients with supratentorial hypertensive ICH. Moreover, the patients who underwent neuroendoscopy had a higher evacuation rate, lower risk of complications, and shorter operation time compared with those that underwent a craniotomy.

ObjectiveNeutrophil to lymphocyte ratio (NLR) is used as an independent predictor for clinical outcomes in cancers, cardiovascular disorders and ischemic stroke. The prognostic role of NLR in spontaneous intracerebral hemorrhage (sICH) is still controversial. The aim of this report is to conduct a meta-analysis to evaluate the prognostic significance NLR in patients with sICH.Materials and MethodsAll related articles were searched on PubMed, EMBASE, Cochrane Central Register of Controlled Trials followed the PRISMA flow diagram. The quality of eligible studies were evaluated and the related data were extracted by two reviewers independently. The end points included the mortality and poor outcomes and subgroup analyses were performed.ResultsFive studies with 1944 subjects were included and had acceptable quality. The high NLR had a higher risk of in-hospital mortality (OR: 0.97; 95% CI: 0.94–0.99, p = 0.02) and 90-day mortality (OR: 2.43; 95% CI: 1.01–5.83, p = 0.047); without association with the poor outcomes (OR: 1.17; 95% CI: 0.93–1.47, p = 0.18). After subgroup analyses, the high NLR correlated with an increased 90-day mortality in the high cut-off group (OR: 1.56; 95% CI: 1.15–2.13, p = 0.005). The high NLR additionally predicts poor outcomes in smaller hematoma group (OR: 1.16; 95% CI: 1.01–1.32, p = 0.04) and the high cut-off group (OR: 2.20; 95% CI: 1.54–3.14, p < 0.001).ConclusionsThe high NLR was significantly associated with in-hospital and 90-day mortality in patients with sICH. The NLR with cut-off of 7.5 had statistically significant potential for predicting mortality and poor outcomes, regardless of country, time of laboratory test and hematoma volumes.

Our meta-analysis suggests that LC is a safe and feasible technique for TCC associated with less estimated blood loss, fewer total postoperative complications, quicker recovery of intestinal function, shorter length of hospital stay, and equivalent long-term outcomes. Furthermore, a large-scaled, prospective randomized controlled study is warranted to verify those results.

Intraventricular hemorrhage (IVH) was associated with poor outcomes in patients with intracerebral hemorrhage. IVH had a high incidence in patients with ruptured arteriovenous malformations (AVMs). In this study, we aimed to discuss the clinical features and prognostic factors of outcomes in the patients with AVM-related IVH.From January 2010 to January 2016, we collected the data of the patients with AVM-related IVH retrospectively. The data, including clinical and radiological parameters, were collected to evaluate the clinical features. Univariate and multivariate logistic regression analyses were used to identify the prognostic factors for clinical outcomes (hydrocephalus, 6-month outcomes measured by the modified Rankin scale) in our cohort.A total of 67 eligible patients were included and 19 patients (28%) only presented with IVH. Thirty-three patients (49%) presented hydrocephalus, and 12 patients (18%) presented brain ischemia. Nineteen patients (28%) had a poor outcome after 6 months. In multivariate logistic regression, subarachnoid hemorrhage (SAH) (P = .028) was associated with hydrocephalus and higher Graeb score (P = .080) tended to increase the risk of hydrocephalus. The high Glasgow coma scale (P = .010), large hematoma volume of parenchyma (P = .006), and high supplemented Spetzler–Martin (sup-SM) score (P = .041) were independent factors of the poor outcome.IVH was common in ruptured AVMs and increased the poor outcomes in patients with the ruptured AVMs. The AVM-related IVH patients had a high incidence of hydrocephalus, which was associated with brain ischemia and SAH. Patients with lower Glasgow coma scale, lower sup-SM score, and smaller parenchymal hematoma had better long-term outcomes.

OBJECTIVERupture of arteriovenous malformations (AVMs) would result in high mortality and prevalence of disability in pediatric patients. Decisions regarding the treatment of AVMs need to weigh the risk of rupture over the course of their natural history against the possibility of creating a lesion during treatment. Multiple factors have been proposed to predict hemorrhagic presentation of pediatric patients with AVMs. The aim of this meta-analysis was to evaluate the predictors of hemorrhagic presentation in pediatric patients with AVMs.METHODSThe authors searched the PubMed and EMBASE databases. Studies reporting the predictors of hemorrhagic presentation in children with untreated brain AVMs were included. The predictive ability of identified predictors was assessed by odds ratios (ORs) and 95% confidence intervals (CIs).RESULTSA higher risk of hemorrhagic presentation was found in AVMs with smaller size (< 3 cm, OR 2.97, 95% CI 1.94–4.54, p < 0.00001), deep venous drainage (OR 2.28, 95% CI 1.55–3.36, p < 0.0001), a single draining vein (OR 2.23, 95% CI 1.27–3.92, p = 0.005), a single feeder (OR 3.72, 95% CI 1.31–10.62, p = 0.01), a deep location (OR 1.82, 95% CI 1.22–2.72, p = 0.004), an infratentorial location (OR 2.25, 95% CI 1.19–4.26, p = 0.01), and diffuse morphology (OR 8.94, 95% CI 3.01–26.55, p < 0.0001). In addition, the AVMs with draining vein ectasia (OR 0.35, 95% CI 0.13–0.97, p = 0.04) and high Spetzler-Martin (SM) grade (OR 0.53, 95% CI 0.36–0.78, p = 0.001) had a lower risk of hemorrhagic presentation in pediatric patients.CONCLUSIONSSmaller AVMs, deep venous drainage, a single draining vein, a single feeder, deep/infratentorial location, diffuse morphology, and high SM grade were identified as positive predictors for hemorrhagic presentation. Particularly, patients with diffuse AVMs have a higher risk of hemorrhagic presentation than other factors and may need active treatments. However, factors such as age, sex, draining vein stenosis, and associated aneurysms were not associated with hemorrhagic presentation.

Introduction:Antihypertensive treatment is associated with clinical outcomes in patients with spontaneous intracerebral hemorrhage (sICH). ADAPT showed that intensive blood pressure lowering (<140 mm Hg) does not reduce peri-hematoma regional cerebral blood flow (rCBF) in patients with sICH. However, the stenosis of main cerebral arteries that has a high presence in patients with sICH is well-known related to the brain ischemia. The effect of intensive BP lowering for sICH in patients with cerebrovascular stenosis is still unknown.Aim:The aim of this study was to determine the safety and effectiveness of intensive BP lowering for sICH in patients with cerebrovascular stenosis.Methods and analysis:A pilot trial has been conducted to calculate the sample size and 80 patients of sICH with cerebrovascular stenosis will be involved. The target of systolic blood pressure (SBP) will be maintained at from 120 to 140 mm Hg or from 140 to 180 mm Hg for 7 days. Cerebral ischemia will be assessed at 24 hours after onset by computed tomography (CT) perfusion imaging and the follow-up will be conducted at 30-day and 90-day. The primary outcome is the reduction of peri-hematoma rCBF. The other cerebral perfusion indexes and the rate of ischemic stroke are regarded as other primary outcomes. The secondary outcomes include clinical outcome at 30 days and 90 days, complications, and hospital stays.Discussion:The ATICHST trial has been signed as a parallel, prospective, randomized, assessor-blinded clinical trial to determine the effects of intensive BP lowering on sICH in patients with cerebrovascular stenosis, the results of which will contribute to guide the management of blood pressure in sICH.Conclusion:The protocol will determine the safety and effectiveness of intensive BP lowering for sICH with cerebrovascular stenosis.
