Severe Cerebral Vasospasm and Childhood Arterial Ischemic Stroke After Intrathecal Cytarabine
We report on 2 patients who developed widespread cerebral vasospasm and arterial ischemic strokes (AIS) after application of intrathecal (IT) cytarabine. In a 3-year-old child with acute lymphoblastic leukemia (ALL), left leg weakness, hyperreflexia, and clonus were noted 4 days after her first dose of IT cytarabine during the induction phase of her chemotherapy. Cerebral MRI revealed multiple acute cerebral ischemic infarcts and widespread cerebral vasospasm. A 5-year-old girl complained of right arm and leg pain and began limping 11 days after IT cytarabine. Symptoms progressed to right dense hemiplegia, left gaze deviat...

Sig1R Stimulates Cancer Cell Invasiveness
In this study, we found that Sig1R dynamically controls the membrane expression of the human voltage-dependent K+ channel human ether-à-go-go-related gene (hERG) in myeloid leukemia and colorectal cancer cell lines. Sig1R promoted the formation of hERG/β1-integrin signaling complexes upon extracellular matrix stimulation, triggering the activation of the PI3K/AKT pathway. Consequently, the presence of Sig1R in cancer cells increased motility and VEGF secretion. In vivo, Sig1R expression enhanced the aggressiveness of tumor cells by potentiating invasion and angiogenesis, leading to poor survival. Collectively, our findin...

Leukemia Inhibitory Factor Protects Neurons from Ischemic Damage via Upregulation of Superoxide Dismutase 3
Abstract Leukemia inhibitory factor (LIF) has been shown to protect oligodendrocytes from ischemia by upregulating endogenous antioxidants. The goal of this study was to determine whether LIF protects neurons during stroke by upregulating superoxide dismutase 3 (SOD3). Animals were administered phosphate-buffered saline (PBS) or 125 μg/kg LIF at 6, 24, and 48 h after middle cerebral artery occlusion or sham surgery. Neurons were isolated from rat pups on embryonic day 18 and used between 7 and 15 days in culture. Cells were treated with LIF and/or 10 μM Akt inhibitor IV with PBS and 0.1 % DMSO acting as veh...

Statistical methods for studying disease subtype heterogeneity
A fundamental goal of epidemiologic research is to investigate the relationship between exposures and disease risk. Cases of the disease are often considered a single outcome and assumed to share a common etiology. However, evidence indicates that many human diseases arise and evolve through a range of heterogeneous molecular pathologic processes, influenced by diverse exposures. Pathogenic heterogeneity has been considered in various neoplasms such as colorectal, lung, prostate, and breast cancers, leukemia and lymphoma, and non‐neoplastic diseases, including obesity, type II diabetes, glaucoma, stroke, cardiovascular d...

Cervical aspergillosis with dissemination to the central nervous system: Case reports and review of the literature.
CONCLUSION: IA must be considered a possibility whenever an immunocompromised patient presents with a new brain lesion. These lesions require surgical evacuation, a procedure that allows for diagnostic confirmation and enhances prognosis. Appropriate anti-fungal therapy must be started as soon as the diagnosis is confirmed. In addition, the patient's neurological exam must be repeated and images obtained periodically to monitor treatment and detect possible recurrences. PMID: 26600985 [PubMed - as supplied by publisher]

Transfusion strategy in hematological intensive care unit: study protocol for a randomized controlled trial
Background: Packed red blood cell (PRBC) transfusion is required in hematology patients treated with chemotherapy for acute leukemia, autologous (auto) or allogeneic (allo) hematopoietic stem cell transplantation (HSCT). In certain situations like septic shock, hip surgery, coronary disease or gastrointestinal hemorrhage, a restrictive transfusion strategy is associated with a reduction of infection and death. A transfusion strategy using a single PRBC unit has been retrospectively investigated and showed a safe reduction of PRBC consumption and costs. We therefore designed a study to prospectively demonstrate that the tra...

The Stigma Ends Now
Did you smoke? That is often one of the first responses patients hear when they tell people about their lung cancer diagnosis. For decades lung cancer has been singled out as THE smoker's disease, despite evidence that over 30 other deadly diseases are directly linked to tobacco consumption. In fact, a recent study published in the New England Journal of Medicine found that breast cancer, prostate cancer, kidney failure and diabetes are among those smoking-related diseases. This connection between tobacco and serious illnesses other than lung cancer has been known for quite a while. The U.S. surgeon general lists smoking ...

Positive perspectives from proton therapy
Emma Louise WaltonBiomedical Journal 2015 38(5):361-364In this issue of the Biomedical Journal, we take a look at some of the benefits of proton therapy, which is an emerging technique in cancer treatment and highlight an animal study, showing that a common fruit ripening agent is toxic when used in excessive doses. Finally, this issue includes reports that shed light on the genetics of stroke and childhood leukemia.

Abstract 5267: Comorbidity and cause of death in patients with chronic lymphocytic leukemia (CLL)
Conclusions. Despite the advanced age at CLL diagnosis, the frequent presence of comorbidities, and the indolent nature of the disease, CLL progression is the ultimate cause of death in 51% of newly diagnosed CLL patients, with an additional 26% dying of causes potentially related to CLL, such as infections and second cancers. The influence of comorbidities and other clinical factors at diagnosis (e.g. smoking, Charlson Comorbidity Index) on survival and ultimate cause of death are being abstracted, and will be presented at the meeting.Citation Format: Paolo Strati, Kari Chaffe, Sara Achenbach, Timothy Call, Neil Kay, Jame...

Effects of Salvia miltiorrhiza on CNS Neuronal Injury and Degeneration: A Plausible Complementary Role of Tanshinones and Depsides
Planta MedDOI: 10.1055/s-0035-1546196 Salvia miltiorrhiza is a very important herbal drug of traditional Chinese medicine. Bioactive constituents are represented by two main groups of secondary metabolites, the lipophilic diterpenic quinones known as tanshinones and the hydrophilic depsides known as salvianolic acids. S. miltiorrhiza extracts and single constituents have been shown to have positive effects in central nervous system neuronal injury and degeneration in several animal models by various biological mechanisms. Both tanshinones and depsides protect against β-amyloid-induced toxicity, but their mechanis...

Central Nervous System Complications and Outcomes after Allogeneic Hematopoietic Stem Cell Transplantation
Conclusions The occurrence of CNSCs after ALLO-HSCT was associated with reduced survival. Identifying patients at risk, monitoring, early detection and management of CNSCs post ALLO-HSCT is needed to improve outcomes. Teaser This retrospective study of 351 patients, who have undergone allogeneic hematopoietic stem cell transplantation between 2002 and 2011 at the University of Nebraska Medical Center, demonstrated 12% incidence of central nervous system complications. The most common complications included posterior reversible encephalopathy syndrome (40%), stroke or transient ischemic attack (24%), seizures (20%), and inf...

Inflammatory Claims About Inflammation
We all appreciate the elegance of simple solutions to complex problems. But we know too that simplicity can often masquerade as truth, hiding a more nuanced reality. Such is the case with inflammation, where pseudoscience, exaggerated claims, false promises, and dangerous oversimplification have dominated for too long. Here is a typical missive: "Inflammation controls our lives. Have you or a loved one dealt with pain, obesity, ADD/ADHD, peripheral neuropathy, diabetes, heart disease, stroke, migraines, thyroid issues, dental issues, or cancer? If you answered yes to any of these disorders you are dealing with inflammatio...

Daucosterol protects neurons against oxygen–glucose deprivation/reperfusion-mediated injury by activating IGF1 signaling pathway
In this study, we investigated the effects of daucosterol on the survival of cultured cortical neurons after neurons were subjected to oxygen and glucose deprivation and simulated reperfusion (OGD/R) 2 2 OGD/R, oxygen and glucose deprivation and simulated reperfusion. , and determined the corresponding molecular mechanism. The results showed that post-treatment of daucosterol significantly reduced neuronal loss, as well as apoptotic rate and caspase-3 activity, displaying the neuroprotective activity. We also found that daucosterol increased the expression level of IGF1 protein, diminished the down-regulation of p-AKT 3 ...
