The endothelial-enriched lncRNA LINC00607 mediates angiogenic function.

Long non-coding RNAs (lncRNAs) can act as regulatory RNAs which, by altering the expression of target genes, impact on the cellular phenotype and cardiovascular disease development. Endothelial lncRNAs and their vascular functions are largely undefined. Deep RNA-Seq and FANTOM5 CAGE analysis revealed the lncRNA LINC00607 to be highly enriched in human endothelial cells.

The Effect of Losartan on Neuroinflammation as Well as on Endothelin-1- and Serotonin-Induced Vasoconstriction in a Double-Haemorrhage Rat Model.

Poor patient outcome after aneurysmal subarachnoid haemorrhage (SAH) is due to a multifactorial process. Delayed cerebral vasospasm, ischemic neurological deficits, and infarction are the most feared acute sequelae triggered by enhanced synthesis of serotonin and endothelin-1 (ET-1). During the past decades, multiple drugs have been analysed for protective effects without resounding success.

Impact of COVID-19 Pandemic on Treatment Management and Clinical Outcome of Aneurysmal Subarachnoid Hemorrhage - A Single-Center Experience.

Background: Previous studies reported decreased volumes of acute stroke admissions during the COVID-19 pandemic. We aimed to examine whether aneurysmal subarachnoid hemorrhage (aSAH) volumes demonstrated similar declines in our department. Furthermore, the impact of the pandemic on disease progression should be analyzed.

Short- and Long-Term Effects of Rehabilitation after Perimesencephalic Subarachnoid Hemorrhage.

In about 25% of patients with spontaneous subarachnoid hemorrhage (SAH), a bleeding source cannot be identified during radiological diagnostics. Generally, the outcome of perimesencephalic or prepontine (PM) SAH is known to be significantly better than after non-PM SAH. Data about long-term follow-up concerning physical and mental health are scarce, so this study is reports on long-term results.

Statins Improve Clinical Outcome After Non-aneurysmal Subarachnoid Hemorrhage: A Translational Insight From a Systematic Review of Experimental Studies.

The efficacy of statin-treatment in aneurysmal subarachnoid hemorrhage (SAH) remains controversial. We aimed to investigate the effects of statin-treatment in non-aneurysmal (na)SAH in accordance with animal research data illustrating the pathophysiology of naSAH. We systematically searched PubMed using PRISMA-guidelines and selected experimental studies assessing the statin-effect on SAH.

Levosimendan as a therapeutic strategy to prevent neuroinflammation after aneurysmal subarachnoid hemorrhage?

Background: Poor patient outcomes after aneurysmal subarachnoid hemorrhage (SAH) occur due to a multifactorial process, mainly involving cerebral inflammation (CI), delayed cerebral vasospasm (DCVS), and delayed cerebral ischemia, followed by neurodegeneration. CI is mainly triggered by enhanced synthesis of serotonin (5-HT), prostaglandin F2alpha (PGF2a), and cytokines such as interleukins. Levosimendan (LV), a calcium-channel sensitizer, has already displayed anti-inflammatory effects in patients with severe heart failure.

Multidrug-resistant organisms (MDROs) in patients with subarachnoid hemorrhage (SAH).

Patient care in a neurointensive care unit (neuro-ICU) is challenging. Multidrug-resistant organisms (MDROs) are increasingly common in the routine clinical practice. We evaluated the impact of infection with MDROs on outcomes in patients with subarachnoid hemorrhage (SAH).

Short- and midterm outcome of ruptured and unruptured intracerebral wide-necked aneurysms with microsurgical treatment.

To clip or coil has been matter of debates for several years and is the domain of interdisciplinary decision making. However, the microsurgical outcome has still been elusive concerning wide neck aneurysms (WNA). A retrospective single center study was performed with all patients with ruptured WNA (rWNA) and unruptured WNA (uWNA) admitted to author´s institute between 2007-2017.

Beware of Nihilism: Favorable Outcome despite Poor Admission Status in Posterior Circulation Aneurysms after Aneurysmal Subarachnoid Hemorrhage.

Objective:  As shown in a previous study, aneurysm location seems to influence prognosis in patients with subarachnoid hemorrhage (SAH). We compared patients with ruptured aneurysms of anterior and posterior circulation, undergoing coil embolization, concerning differences in outcome and prognostic factors.

Methods:  Patients with SAH were entered into a prospectively collected database.

Vitamin D-A New Perspective in Treatment of Cerebral Vasospasm.

Background: Cerebral vasospasm (CVS) is a frequent complication after subarachnoid hemorrhage (SAH), with no sufficient therapy and a complex pathophysiology.

Objective: To explore the vitamin D system as a potential treatment for CVS.

Methods: 25-vitamin D3 levels tested between 2007 and 2015 and data of SAH patients admitted during the months with a peak vs nadir of VitD3 values were analyzed, retrospectively.

The Role of Losartan as a Potential Neuroregenerative Pharmacological Agent after Aneurysmal Subarachnoid Haemorrhage.

Background: Cerebral vasospasm (CVS) remains a major cause of delayed cerebral ischaemia following aneurysmal subarachnoid haemorrhage (SAH), making it a life-threatening type of stroke with high morbidity and mortality. Endothelin-1 is known as key player mediating a strong vasocontractile effect. Interestingly, losartan restores the impaired vasorelaxative ET(B) receptor function in a non-competitive direct fashion.

Does aneurysm side influence the infarction side and patients´ outcome after subarachnoid hemorrhage?

Background: The prognostic factors and outcome of aneurysms appear to be dependent on its locations. Therefore, we compared left- and right- sided aneurysms in patients with aneurysmal subarachnoid hemorrhage (SAH) in terms of differences in outcome and prognostic factors.

Methods: Patients with SAH were entered into a prospectively collected database.

Vitamin K Antagonist (Phenprocoumon) and Subarachnoid Hemorrhage: A Single-Center, Matched-Pair Analysis.

Background: Demographic changes are leading to an aging society with a growing number of patients relying on anticoagulation, and vitamin K antagonists (VKA) are still widely used. As mortality and functional outcomes are worse in case of VKA-associated hemorrhagic stroke, phenprocoumon treatment seems to be a negative prognostic factor in case of subarachnoid hemorrhage (SAH). The purpose of this study was to analyze whether phenprocoumon treatment does worsen the outcome after non-traumatic SAH.

Pain medication at ictus of subarachnoid hemorrhage-the influence of one-time acetylsalicylic acid usage on bleeding pattern, treatment course, and outcome: a matched pair analysis.

Acetylsalicylic acid (ASA) is a well-known and widely used analgesic for acute pain. Patients with acute headache due to subarachnoid hemorrhage (SAH) are inclined to take ASA in this situation. Due to the antithrombotic effects, ASA intake is related to higher bleeding rates in case of hemorrhage or surgical treatment.

Influence of ABO blood type on the outcome after non-aneurysmal subarachnoid hemorrhage.

Background: In patients with non-aneurysmal subarachnoid hemorrhage (NA-SAH), the etiology is unknown and the bleeding source remains unidentified. However, the ABO blood type system has a profound role in patient's hemostasis and thrombosis. To date, the aspect of ABO blood type in incidence, clinical course, and outcome after NA-SAH has not been investigated.

A benchmark approach to hemorrhage risk management of cavernous malformations.

Objective: Despite the low annual risk of hemorrhage associated with a cavernous malformation (CM) (0.6%-1.1% per year), the risk of rehemorrhage rate and severity of neurologic deficits is significantly higher; therefore, we aimed to evaluate the rupture risk of CMs depending on various factors.

Continuous Acetylsalicylic Acid Treatment Does Not Influence Bleeding Pattern or Outcome of Aneurysmal Subarachnoid Hemorrhage: A Matched-Pair Analysis.

Objective: Demographic changes are leading to an aging society with a growing number of patients with cardiovascular diseases, relying on antiplatelet drugs like acetylsalicylic acid (ASA). Although antiplatelet agents are suspected to be protective not only in the cardiologic but in the neurovascular field, the alteration of the coagulating process could have a major impact on the course and outcome after rupture of intracranial aneurysms.

Methods: Between June 1999 and December 2014, 1422 patients were treated for aneurysmal SAH in our institution, 144 (10.

Positive influence of partial resection on overall survival of patients with overlapping glioblastomas.

Objectives: Patients with overlapping glioblastomas (former known as gliomatosis cerebri according to the 2007 WHO classification) have a poor prognosis. Most of the patients undergo biopsy to confirm histopathological diagnosis. Treatment comprises chemotherapy, radiation and combination of both.

Cerebral Vasospasm-Dependent and Cerebral Vasospasm-Independent Cerebral Infarctions Predict Outcome After Nonaneurysmal Subarachnoid Hemorrhage: A Single-Center Series with 250 Patients.

Objective: The number of patients with nonaneurysmal subarachnoid hemorrhage (naSAH) has increased during the last decade. Data regarding infarctions in naSAH are still limited. The aim of this study was to identify the rate of cerebral vasospasm (CVS)-dependent and CVS-independent infarctions and their influence on clinical outcomes.

MRI-detection rate and incidence of lumbar bleeding sources in 190 patients with non-aneurysmal SAH.

Background: Up to 15% of all spontaneous subarachnoid hemorrhages (SAH) have a non-aneurysmal SAH (NASAH). The evaluation of SAH patients with negative digital subtraction angiography (DSA) is sometimes a diagnostic challenge. Our goal in this study was to reassess the yield of standard MR-imaging of the complete spinal axis to rule out spinal bleeding sources in patients with NASAH.

Effect of heparin on secondary brain injury in patients with subarachnoid hemorrhage: an additional 'H' therapy in vasospasm treatment.

Objective: Secondary brain injury leads to high morbidity and mortality rates in patients with aneurysmal subarachnoid hemorrhage (aSAH). However, evidence-based treatment strategies are sparse. Since heparin has various effects on neuroinflammation, microthromboembolism and vasomotor function, our objective was to determine whether heparin can be used as a multitarget prophylactic agent to ameliorate morbidity in SAH.

Aneurysm Location as a Prognostic Outcome Factor After Subarachnoid Hemorrhage From Internal Carotid Artery Aneurysms and Potential Impact for Further Experimental Subarachnoid Hemorrhage Models.

Objective: Prognostic factors of favorable and unfavorable clinical outcome after aneurysmal subarachnoid hemorrhage (SAH) are still not completely known. We retrospectively analyzed the aneurysm location as a factor for patients' outcome after aneurysmal SAH.

Methods: We retrospectively selected patients from our prospectively collected database with aneurysm at the carotid bifurcation artery (n = 23) and posterior communicating artery (n = 170).

Benefit of Stereotactic Procedures in a Series of 43 Children.

Objectives: Stereotactic biopsies are procedures that enable neurosurgeons to obtain tissue samples of brain tumors located in eloquent areas with a low risk of perioperative complications. In this study, we examined stereotactic procedures (STX) in children. We focused on effectiveness, safety, and histopathological results to evaluate the benefits of the procedure.

Non-aneurysmal non-perimesencephalic subarachnoid hemorrhage: effect of rehabilitation at short-term and in a prospective study of long-term follow-up.

Background: A recently published prospective study identified an impaired outcome of patients with non-perimesencephalic (NPM) subarachnoid hemorrhage (SAH). Our objective was to analyze the long-term outcome of patients with subsequent rehabilitation after NPM SAH.

Methods: A comparison of patients with NPM SAH receiving subsequent in-patient rehabilitation was done at discharge (using the modified Rankin scale (mRS)), short-term outcome after 6 months (mRS), and prospectively using a questionnaire (short-form health survey with 36 questions (SF-36)), which was sent to 66 patients.

Cerebral vasospasm and delayed cerebral infarctions in 225 patients with non-aneurysmal subarachnoid hemorrhage: the underestimated risk of Fisher 3 blood distribution.

Objective: Recent data have shown increasing numbers of non-aneurysmal subarachnoid hemorrhage (NASAH). However, data are limited and often only small series have been published. Our objective was to analyze the rate of cerebral vasospasm (CVS), delayed cerebral infarction (DCI), and their influence on the clinical outcome, especially in patients with diffuse Fisher 3 bleeding pattern NASAH (Fi3).
