Targeted Cancer Therapies.
Abstract Targeted cancer therapies involve chemotherapeutic agents that attack, directly or indirectly, a specific genetic biomarker found in a given cancer. Targeted oncology includes monoclonal antibodies, small molecule inhibitors, antibody-drug conjugates, and immunotherapy. For example, the monoclonal antibodies trastuzumab and pertuzumab target human epidermal growth factor receptor 2 (HER2) and are used when treating HER2-positive breast cancer. Although targeted oncology has improved survival by years for some incurable cancers such as metastatic breast and lung cancer, as few as 8% of patients with advanc...

New-onset Post-transplant Diabetes and Therapy in Long-term Survivors After Allogeneic Hematopoietic Stem Cell Transplantation
Conclusion: After allo-HSCT, a significant number of patients developed PTDM and patients with acute graft-versus-host-disease were found to have a higher risk for PTDM. Long-term and continuous follow-up for diabetes and cardiovascular risk factors after HSCT is important in order to be able to provide timely and appropriate treatment.

Severe, Fatal Methotrexate-related Neurotoxicity in 2 Adolescent Patients With ALL
Neurotoxicity is a well-documented adverse effect of methotrexate in the treatment of pediatric cancers. The spectrum of symptoms is broad, can include stroke-like episodes and seizures, and classically resolves within days. The majority of patients tolerate subsequent doses without recurrence of symptoms. The population of patients who experience persistent and irreversible neurologic symptoms is poorly described, with the existing literature suggestive of a relationship with radiation therapy. The authors present a case series of 2 patients with pre-B-cell acute lymphoblastic leukemia who developed severe and ultimately ...

Four-Dimensional Echocardiographic Evaluation of Left Ventricular Systolic Functions in Patients with Chronic Myeloid Leukaemia Receiving Tyrosine Kinase Inhibitors.
Abstract Tyrosine kinase inhibitors (TKIs) are established treatment for haematological malignancies. However, cardiac adverse effects, including the reduction in left ventricular ejection fraction and symptomatic heart failure remain clinical problems. The purpose of this study was to evaluate the left ventricular systolic functions in patients with chronic myeloid leukaemia receiving TKIs. A cross-sectional and observational study was conducted of 37 patients with chronic myeloid leukaemia receiving dasatinib or nilotinib after imatinib failure. Left ventricular systolic functions were evaluated using four-dimen...

Prevalence of leukoencephalopathy and its potential cognitive sequelae in cancer patients.
In conclusion, leukoencephalopathy is well-documented for ALL patients (with a focus on methotrexate), but there is a lack of knowledge for other intravenous chemotherapeutics, other oncological populations, wider age ranges and possible risk factors (e.g. history of CNS event). Furthermore, the long-term neuropsychological impact and potential risk for neurodegenerative processes due to leukoencephalopathy remains inconclusive. Hence, large international databanks, epidemiological and prospective case-control studies are necessary to stratify risk groups for CNS-related side effects.

Progressive thrombosis of cervical and intracranial arteries related to Ponatinib treatment for Chronic Myeloid Leukemia
Ponatinib is a third-generation Tyrosine Kinase Inhibitor (TKI), approved as first-line treatment for Chronic Myeloid Leukaemia (CML) chronic phase.Here we describe a CML patient with a history of subsequent TIAs and an ischemic stroke during Ponatinib treatment. Patient was admitted for a 3-day history of sudden onset left hemiparesis due to an acute ischemic stroke. MRI showed bilaterally the almost total absence of signal in the intracranial tract of anterior circulation and low signal of cerebral posterior circulation.

Development of DDS Actively to Overcome the Blood-brain Barrier in the Region of Ischemic Stroke.
Abstract We previously showed that increased permeability of the blood-brain barrier (BBB) after ischemic stroke enables extravasation of nano-sized liposomes and accumulation in the ischemic region, and that delivery of neuroprotective agents using liposomal drug delivery systems (DDS) is applicable for treating cerebral ischemia/reperfusion (I/R) injury. However, entry of liposomes into the brain parenchyma was limited in the early stages after I/R possibly due to microvascular dysfunction induced by pathological progression. As such, new approaches to overcome the BBB are needed. Leukocytes can pass through inf...

Mixed Lineage Leukemia 1 Promoted Neuron Apoptosis in Ischemic Penumbra via Regulating ASK-1/TNF- α Complex
This study aimed to explore the underlying mechanism of neuron apoptosis in ischemic penumbra via histone methyltransferase (HMT) mixed lineage leukemia 1 (MLL1) mediated epigenetic pathway. Mouse IS model was established by middle cerebral artery occlusion (MCAO). Mouse primary cortical mixed cells were cultured and treated with oxygen–glucose deprivation (OGD) to simulate IS process. The expressions of apoptosis signal regulating kinase-1 (ASK-1), pASK-1, cleaved caspase-3, ASK-1/serine–threonine kinase receptor-associated protein (STRAP)/14-3-3 complex, ASK-1/tumor necrosis factor-α (TNF-α) complex, and MLL1 in mo...

Cancers, Vol. 12, Pages 1285: Genome-Wide Association Meta-Analysis of Single-Nucleotide Polymorphisms and Symptomatic Venous Thromboembolism during Therapy for Acute Lymphoblastic Leukemia and Lymphoma in Caucasian Children
Conclusion: This represents the largest GWAS meta-analysis conducted to date associating SNPs to VTE in children and adolescents treated on childhood ALL protocols. Validation of these findings is needed and may then lead to patient stratification for VTE preventive interventions. As VTE hemostasis involves multiple pathways, a more powerful GWAS is needed to detect combination of variants associated with VTE.

A Case of Multiple Sclerosis —Like Relapsing Remitting Encephalomyelitis Following Allogeneic Hematopoietic Stem Cell Transplantation and a Review of the Published Literature
Complications involving the central nervous system (CNS) occur in 9–14% of patients following allogeneic hematopoietic stem cell transplantation (HSCT), including stroke-like episodes, demyelination, encephalitis, and nonspecific neurological symptoms. Here we report a case of multiple sclerosis (MS) like relapsing remitting encephalomyelitis following allogeneic HSCT, which did not respond to disease modifying therapies (DMTs) and “domino” autologous HSCT. A 53-year-old male was treated with allogeneic HSCT for lymphoid blast transformation of chronic myeloid leukemia. Ten months later he presented with confusion, s...

Respiratory Variations in Aortic Blood Flow to Predict Volume Responsiveness in Ventilated Children With Leukemia and Neutropenic Septic Shock*
Conclusions: Respiratory variation in velocity time integral of aortic blood flow and respiratory variation in peak velocity of aortic blood flow derived from transthoracic echocardiography showed only a fair reliability in predicting volume responsiveness in ventilated children with leukemia and neutropenic septic shock.

Vitronectin mitigates stroke-increased neurogenesis only in female mice and through FAK-regulated IL-6.
Abstract Vitronectin (VTN) is a blood protein produced mainly by the liver. We show that VTN leaks from the bloodstream into the injury site and neighboring subventricular zone (SVZ) following ischemic stroke (middle cerebral artery occlusion, MCAO) in adult mice. MCAO is known to increase neurogenesis after stroke. VTN inhibits this response in females, but not in males, as shown by ~70% more stroke-induced SVZ neurogenesis in female VTN-/- mice at 14 d. In female VTN-/- mice, stroke-induced expression of interleukin-6 (IL-6) at 24 h was reduced in the SVZ. The closely related leukemia inhibitory factor (LIF) o...
