Adjuvant radiotherapy after brain metastasectomy: analysis of consecutive cohort of 118 patients from real world practice.

Background: The aim of this retrospective study is to analyze a consecutive cohort of brain metastasis (BM) patients treated off clinical trials through combination of surgery and radiotherapy over the last 15 years in a tertiary neurooncology center.

Materials And Methods: All BM patients operated between 2007-2019 received adjuvant linac-based radiotherapy categorized to whole brain radiotherapy (WBRT) and tumor bed stereotactic radiotherapy. Survival outcomes and local control was analyzed.

Case report: Diagnostic challenge: a new multiple sclerosis "relapse" leading to the diagnosis of anaplastic astrocytoma.

Cerebral tumors and multiple sclerosis (MS) can show overlapping clinical and magnetic resonance imaging (MRI) features and even occur concurrently. Due to the emergence of new symptoms, not usually MS related, an MRI was conducted in a 29-year-old woman with relapsing-remitting MS and showed a significant size progression of a parieto-occipital lesion, with mild clinical correlates, such as blurred vision, difficulty in speaking, and headache. Contrast-enhanced MRI and fluorothymidine positron-emission tomography (PET) did not point toward neoplasm, a lesion biopsy, however, showed astrocytoma, which was confirmed as grade III astrocytoma after the radical resection of the tumor.

Immune system disorders in the early post-injury period in patients after severe brain injury from the perspective of the severity of the injury.

Background: Brain injuries are the most common cause of death in productive age. Besides the extent of the injury, other systemic factors can also affect the outcome. Patients suffering from severe brain injury often experience extracranial inflammatory complications during the early period of treatment.

Current Treatment of Anterior Communicating Artery Aneurysms: Single Center Study.

Introduction: Anterior communicating artery aneurysms (ACoAAs) are the most frequent intracranial aneurysms treated at neurosurgical departments with a vascular program.

Material And Methods: We reviewed patients with ACoAAs in a single institution over ten years (2008-2017). The focus was on the final outcome; complications, age, and clinical condition with respect to modalities were analyzed.

Early Dynamics of Interleukin-6 in Cerebrospinal Fluid after Aneurysmal Subarachnoid Hemorrhage.

Background:  Subarachnoid hemorrhage (SAH) is a severe condition associated with high mortality. Early brain injury (EBI) plays an important role in the pathophysiology of SAH, and inflammation is a major contributor to EBI. Inflammation is a widely studied topic in both experimental and clinical conditions; however, just a few clinical studies have focused primarily on the early inflammatory response after SAH, and detailed information about the association between the dynamics of early inflammatory response with main clinical characteristics is lacking.

Middle cerebral artery aneurysms with intracerebral hematoma-the impact of side and volume on final outcome.

Background: Middle cerebral artery aneurysms (MCA aneurysms) belong to the most frequent type of intracranial aneurysms forming an intracerebral hematoma. The consequences of the hematoma-the laterality, the impact of ICH volume and size of the aneurysm with the final outcome of these patients had not been studied in detail in this location, and we focused on the analysis of these factors.

Methods: Patients with MCA aneurysms and associated intracerebral hematomas with a volume ≥10 ml were studied; these were treated from January 2006 to December 2015.

[The use of telemetric intracranial pressure monitoring in the differential diagnosis of idiopathic intracranial hypertension - a case report].

Idiopathic intracranial hypertension is a disorder that results from an increase of intracranial pressure with unknown cause. A single measurement of intracranial pressure only provides data at one given point in time. Therefore, telemetric monitoring of intracranial pressure was performed in a patient with fluctuating headache and significantly impaired vision, which together accounted for 226.

Reference-dependent preferences for maternity wards: an exploration of two reference points.

It is now well established that a person's valuation of the benefit from an outcome of a decision is determined by the intrinsic "consumption utility" of the outcome itself and also by the relation of the outcome to some reference point. The most notable expression of such reference-dependent preferences is loss aversion. What precisely this reference point is, however, is less clear.

[What is important for Israeli women who give birth? Estimation of the preference structure using a Discrete Choice Experiment (DCE)].

Introduction: This article aims to estimate the preference structure of attributes of maternity-wards, as expressed by Israeli women who recently gave birth.

Research Design: The estimation is based on data generated by an experiment that simulates actual choices of hospital (Discrete Choice experiment). The sample includes 323 women who gave birth in the year 2003 in three large hospitals in the central part of Israel (The Sheba Medical Center, Tel Hashomer; The Rabin Medical Center, Beilinson Campus in Petah Tikva; and the Meir Medical Center in Kfar Saba).

Local fisheries management at the Swedish coast: biological and social preconditions.

Most of the Swedish coastal fisheries are not sustainable from either a social, economic or ecological point of view. We propose the introduction of local fisheries management (LFM) as a tool for restructuring the present large-scale management system in order to achieve sustainability. To implement LFM two questions need to be answered: How to distribute the resource fish among different resource user groups? How to restructure present fisheries management to meet the criteria of sustainability? Starting from these questions we describe possible forms of LFM for Swedish coastal fishery supported by recent research.

[The use of moderate hypothermia in neurosurgery].

Hypothermia is currently considered as the most effective neuroprotective method. In recent years hypothermia has been more and more applied in clinical conditions. Hypothermia has been used with promising results in severe head trauma where it can evidently decrease the intracranial pressure, improve cerebral perfusion pressure and by its direct neuroprotective effect it diminishes the secondary ischemic brain damage.

Stereotactic evacuation of spontaneous infratentorial hemorrhage with monitoring of intracerebral pressure.

Introduction: Based on our experience with stereotactic evacuation of spontaneous supratentorial hematomas this method has also been used for evacuation of spontaneous infratentorial hematoma by the transtentorial approach.

Material And Method: The authors present a series of 6 patients with spontaneous intracerebral hematomas evacuated by the frame-based stereotactic technique, with monitoring of intracranial pressure (ICP) during the stereotactic evacuation. This method was indicated in patients with stable neurological status according to Glasgow Coma Scale (GCS), more than 10.

Is the LDL receptor-related protein involved in Alzheimer's disease?

LDL-related protein receptor (LRP) is the main receptor in the brain for apolipoprotein E. Moreover, the LRP gene is located on chromosome 12, the site of a potential Alzheimer's disease (AD) locus. We explored the association between the LRP gene and AD in 600 French Caucasian patients (37.

The very low density lipoprotein (VLDL) receptor is a genetic susceptibility factor for Alzheimer disease in a European Caucasian population.

The epsilon4 allele of the apolipoprotein E gene (APOE) constitutes a major genetic susceptibility factor for Alzheimer disease (AD). Recently, a polymorphic triplet (CGG) in the very low density lipoprotein receptor (VLDL-R) gene, coding for a receptor binding only apoE-containing lipoproteins, was associated with AD in a Japanese population but not in Caucasian American populations. We explored this association and the potential interaction with the APOE polymorphism in a Caucasian sample of sporadic AD and control subjects of similar ages of European origin.

Application of population pharmacokinetics to the phase II development of an anti-Alzheimer's disease compound, S12024.

Steady-state concentrations of S12024, a novel compound for treatment of Alzheimer's disease, were studied to determine the pharmacokinetic parameters of S12024 in Phase IIa patients and to assess the effect of patient characteristics on those pharmacokinetics. A prospective sparse sampling strategy was used to obtain oral repeated data (n = 285) from 89 patients, which were analyzed using a one-compartment model and the NONMEM computer program. The model suggested that apparent clearance of S12024 was influenced by the study and by patient age.

Cyclin D1 stimulation of estrogen receptor transcriptional activity independent of cdk4.

Cyclin D1 plays an important role in the development of breast cancer and is required for normal breast cell proliferation and differentiation associated with pregnancy. We show that ectopic expression of cyclin D1 can stimulate the transcriptional activity of the estrogen receptor in the absence of estradiol and that this activity can be inhibited by 4-hydroxytamoxifen and ICI 182,780. Cyclin D1 can form a specific complex with the estrogen receptor.

Ras signalling linked to the cell-cycle machinery by the retinoblastoma protein.

The Ras proto-oncogene is a central component of mitogenic signal-transduction pathways, and is essential for cells both to leave a quiescent state (G0) and to pass through the G1/S transition of the cell cycle. The mechanism by which Ras signalling regulates cell-cycle progression is unclear, however. Here we report that the retinoblastoma tumour-suppressor protein (Rb), a regulator of G1 exit, functionally links Ras to passage through the G1 phase.

Structure and partial genomic sequence of the human E2F1 gene.

The E2F family of transcription factors appears to play a critical role in the transcription of certain genes required for cell cycle progression. E2F1, the first cloned member of this family, is regulated during the cell cycle at the mRNA level by changes in transcription of the E2F1 gene and at the protein level by complex formation with proteins such as the retinoblastoma gene product (pRB), cyclin A and DP1. E2F1 can override a pRB-induced G1/S block and can behave as an oncogene in certain cells.
