Background: Activated protein C (APC) inactivates factor V (FV) by cleavage of its heavy chain at Arg306, Arg506, Arg679, and Lys994. Mutational changes, which abolish APC cleavage sites, may predispose thrombosis by altering the inactivation process of FV. FV Leiden (FVL) (Arg506Glu) has been demonstrated as a strong risk factor for thrombosis. In the current study, we have studied whether mutations in the cleavage sites of FV for APC, not due to FVL, would have a role in presenting APC resistance (APCR) and initiation of a cerebral thrombotic event...

PURPOSE: Patient satisfaction with the use of telehealth in disease state management provided by pharmacists has not been fully studied. We hypothesized that patient satisfaction with pharmacist-provided consultations via clinical video teleconferencing (CVT) would not differ from face-to-face delivery. METHODS: Patients were recruited from 2 primary care provider sites from September 2015 to May 2016. Patients completed a survey to evaluate their satisfaction and quality of provider-patient communication with the method in which consultation with a pharmacist was provided...

We report a case of chronic myeloid leukemia (CML) that developed after postoperative chemotherapy with cyclophosphamide, doxorubicin and 5-fluorouracil (CAF) for breast cancer. A 55-year-old woman was diagnosed with invasive ductal carcinoma which was treated with a modified radical mastectomy followed by six cycles of CAF chemotherapy. Nine years later, she developed CML and locoregional recurrence. Her breast recurrence showed strong estrogen receptor, weak progesterone receptor and strong human epidermal growth factor 2 (score 3+) expression...

Temperature dependent rate coefficients for the reactions of Cl atoms with trans-2-butene and isobutene were measured over the temperature range of 263-363K using relative rate technique with reference to 1,3-butadiene, isoprene and 1-pentene. The measured rate coefficients for the reactions of Cl atoms with isobutene and trans-2-butene are k_(R1 )^298K= (3.43±0.11)×10-10 cm3 molecule-1 s-1 and k_(R2 )^298K= (3.20±0.04)×10-10 cm3 molecule-1 s-1 respectively at 298K and 760 Torr. Measured rate coefficients were used to fit the Arrhenius equations, which are obtained to be k_(R1-Exp...

Splanchnic vein thrombosis (SVT) and cerebral vein thrombosis (CVT) are uncommon manifestation of venous thromboembolism (VTE), occurring less frequently than deep vein thrombosis of the lower extremities and pulmonary embolism. SVT encompasses portal vein thrombosis, mesenteric vein thrombosis, splenic vein thrombosis and the Budd-Chiari syndrome. It is therefore a heterogeneous disease, with differences in clinical manifestations according to the site of thrombosis. CVT includes thrombosis of the cortical or deep cerebral veins and thrombosis of the major dural venous sinuses...

OBJECTIVE: Decompressive craniectomy (DC) has been proposed as lifesaving treatment in patients with elevated intracranial pressure, but its effectiveness on reaching favorable neurological outcome remains unclear. We identified predictors of outcome in a large, single-center cohort of patients undergoing DC for different pathologies. METHODS: This retrospective study included all patients undergoing DC from 2006-2014. One-year outcome, assessed using the Glasgow Outcome Scale (GOS), was dichotomized into favorable (GOS 4-5) and unfavorable (GOS 1-3) outcome...

BACKGROUND: To date, very little is known about the effects of direct oral anticoagulants (DOA) use in patients with cervical artery dissection (CAD) and cerebral venous thrombosis (CVT). We present our initial experience with the use of DOA for CAD and CVT and an overview of the published literature. METHODS: From our database, we identified 4 patients who received DOA after CAD and 4 patients after CVT. Also, we analyzed the data reported for 45 patients who received DOA after CAD and 23 after CVT from review of the literature...

The Arl3-Arl1 GTPase cascade plays important roles in vesicle trafficking at the late Golgi and endosomes. Subunits of the conserved oligomeric Golgi (COG) complex, a tethering factor, are important for endosome-to-Golgi transport and contribute to the efficient functioning of the cytoplasm-to-vacuole (Cvt) pathway, a well-known selective autophagy pathway. According to our findings, the Arl3-Arl1 GTPase cascade cooperates with Cog8 to regulate the Cvt pathway via Atg9 trafficking. arl3cog8Δ and arl1cog8Δ exhibit profound defects in aminopeptidase I maturation in rich medium...

Subcutaneous unfractionated heparin (SCUFH) has been proved effective in puerperal cerebral venous thrombosis (CVT), but its efficacy in the more serious form of the disease such as deep CVT patients (DCVT) unreported. We describe the outcomes of 37 (isolated:combined: 11:26) patients of DCVT diagnosed by MRI, treated with SCUFH in a tertiary care stroke unit. It was a prospective observational cohort study using 5000 U of SCUFH every 6 hourly for 10 days with oral Acenocoumarol started on day 7, with monitoring...

BACKGROUND: The effective management of pain in chronic pancreatitis (CP) remains a therapeutic challenge. Analgesic drugs, such as opioids, and the underlying pathology can impair gut function. The autonomic nervous system influences hormone secretion and gut motility. In healthy volunteers, electrical (using noninvasive transcutaneous vagal nerve stimulation [t-VNS]) and physiological (using deep slow breathing [DSB]) modulation of parasympathetic tone results in pain attenuation and enhanced gut motility...

In order to explore the hydrogen abstraction reaction kinetics of unsaturated methyl esters by hydrogen atoms, we selected two molecules for study, in particular methyl 3-butenoate and methyl 2-butenoate, whose C[double bond, length as m-dash]C double bonds are at different locations. We first determined an accurate and efficient electronic structure method for the investigation by considering eight hydrogen abstraction reactions and comparing their barrier heights and reaction energies computed using several exchange-correlation density functionals to those obtained from CCSD(T)-F12a/jun-cc-pVTZ coupled cluster calculations...

BACKGROUND: The presence of Janus Kinase 2 (JAK2) V617F mutation represents a major diagnostic criterion for detecting myeloproliferative neoplasms (MPN) and even in the absence of overt MPN, JAK2 V617F mutation is associated with splanchnic vein thrombosis. However, the actual prevalence and diagnostic value of the JAK2 V617F mutation in patients with cerebral venous thrombosis (CVT) are not known. The aims of this study were to assess the prevalence of JAK2 V617F mutation in a large group of consecutive CVT patients, to detect clinical, biological, and radiological features associated with the mutation, and to determine the long-term venous thrombosis recurrence rate in CVT patients with JAK2 mutation but without overt MPN in order to recommend the best preventive treatment...

Cerebral vein thrombosis (CVT) is a rare disease usually affecting young people, especially women, with a high prevalence of thrombophilic defects. It is known that thrombophilia is associated with pregnancy complications; therefore, a high rate of complications could be expected in women with the previous CVT who become pregnant. This study examined the whole obstetric history of women who suffered from CVT to evaluate the incidence of pregnancy complications during their entire lifespan. We prospectively followed consecutive patients with CVT, limiting the analysis to females and their obstetrical history...

Background: Tumor Necrosis Factor α (TNFα) upregulation during acute inflammatory response has been associated with numerous cardiac effects including modulating Connexin43 and vascular permeability. This may in turn alter cardiac gap junctional (GJ) coupling and extracellular volume (ephaptic coupling) respectively. We hypothesized that acute exposure to pathophysiological TNFα levels can modulate conduction velocity (CV) in the heart by altering electrical coupling: GJ and ephaptic. Methods and Results: Hearts were optically mapped to determine CV from control, TNFα and TNFα + high calcium (2...

Cerebral Vein Thrombosis (CVT) is an uncommon cause of stroke. Thrombosis can occur in superficial veins, deep venous system or cortical veins of brain. The term Deep Cerebral Vein Thrombosis (DCVT) is used for thrombosis of internal cerebral vein, vein of Galen and basal vein of Rosenthal. Only 10% cases of CVT are because of thrombosis of deep cerebral vein. The diagnosis of DCVT is often missed because of its heterogenous presentation. Herein, we present a case of DCVT which was initially treated as meningoencephalitis...

BACKGROUND: The role of PAI-1 4G/5G polymorphism in venous thrombosis has been contradictory. PAI-1 4G/4G genotype is associated with elevated levels of PAI-1 resulting in a hypofibrinolytic state and a higher thrombotic risk. OBJECTIVE: In this study, the distribution of genotypes and frequency of alleles of the 4G/5G polymorphism of PAI-1 gene in Indian patients with different types of venous thrombosis was investigated for its role in development of thrombosis...
