#1
Maria Tountopoulou, Bernhard Weschke, Angela M Kaindl
Lacosamide (LCM) due to no known drug interaction and the absence of metabolic enzyme induction is a good candidate for an add-on medication, especially in combination with lamotrigine, levetiracetam (LEV), oxcarbazepine, topiramate, and valproic acid (VPA). Here we report for the first time, to our knowledge, that LCM can lower VPA and LEV serum levels. At present, there are no known explicable mechanisms of action of LCM, which lowers VPA and LEV. Here observed drug interaction of LCM is of clinical significance, which might be useful for other colleagues in the field...

A common situation in the evaluation of intervention programs is the researcher's possibility to rely on two waves of data only (i.e., pretest and posttest), which profoundly impacts on his/her choice about the possible statistical analyses to be conducted. Indeed, the evaluation of intervention programs based on a pretest-posttest design has been usually carried out by using classic statistical tests, such as family-wise ANOVA analyses, which are strongly limited by exclusively analyzing the intervention effects at the group level...

T regulatory cells (Tregs) are critical for preventing autoimmunity and suppressing immune responses during cancer and chronic infection. However, the role of Tregs in the generation of vaccine-induced immune memory remains ill-defined. Using the mouse model of lymphocytic choriomeningitis virus (LCMV) infection, we demonstrate that transient absence of Tregs during effector to memory CD8 T cell transition results in a permanent impairment in the maintenance, function, and recall capacity of CD8 T cells. Memory CD8 T cells in mice that were transiently depleted of Tregs exhibited defective upregulation of memory markers with a significant decrease in polyfunctionality...

OBJECTIVE: The intravenous formulation of lacosamide (LCM) and its good overall tolerability and safety favor the use in status epilepticus (SE). The aim of this systematic review was to identify and evaluate studies reporting on the use of LCM in SE. METHODS: We performed a systematic literature search of electronic databases using a combined search strategy from 2008 until October 2016. Using a standardized assessment form, information on the study design, methodologic framework, data sources, efficacy, and adverse events attributed to LCM were extracted from each publication and systematically reported...

An 8-year-old girl presented with back and leg pain and left arm and leg paresis. Lumbar puncture was suggestive of lymphocytic meningitis without identified organism. A second lumbar puncture demonstrated a large number of lymphoid B cells, with positive immunohistochemical staining for CD20 and CD25, proving the diagnosis of neurolymphomatosis. Brain and spine MRI demonstrated involvement of cervical and lumbosacral nerve roots. FDG PET/CT showed multiple bone metastases in addition to nerve involvement. Postchemotherapy FDG PET/CT demonstrated complete metabolic response...

CD4(+) T cells are essential for sustaining CD8(+) T cell responses during a chronic infection. The adoptive transfer of virus-specific CD4(+) T cells has been shown to efficiently rescue exhausted CD8(+) T cells. However, the question of whether endogenous virus-specific CD4(+) T cell responses can be enhanced by certain vaccination strategies and subsequently reinvigorate exhausted CD8(+) T cells remains unexplored. In this study, we developed a CD4(+) T cell epitope-based heterologous prime-boost immunization strategy and examined the efficacy of this strategy using a mouse model of chronic lymphocytic choriomeningitis virus (LCMV) infection...

BACKGROUND AND PURPOSE: Lacosamide (LCM) is an antiepileptic drug that enhances the slow inactivation of sodium channels and modulates collapsin response mediator protein-2. LCM was recently demonstrated to exert a neuroprotective effect in a murine model of traumatic brain injury and status epilepticus. Assuming the same underlying excitotoxicity-related brain injury mechanism, we hypothesized that LCM would have a neuroprotective effect in hypoxic-ischemic brain injury. METHODS: We divided rats into three groups at each testing session: pre- or postfed with LCM, fed with normal saline, and sham...

BACKGROUND: Analysis of cerebrospinal fluid (CSF) obtained by lumbar puncture (LP) is essential for diagnosis of meningitis. What is the impact of the procedure upon the natural history of headache and associated signs in patients with lymphocytic meningitis and what factors can have prognostic value for the future progression of symptomatology? This study was aimed at looking into these questions. METHODS: One hundred and one patients with clinical and laboratory diagnosis of aseptic meningitis answered a questionnaire intended at assessing the severity and nature of headache and meningeal irritation signs before and one, and twenty four hours after the LP...

More than 30 strains of lymphocytic choriomeningitis virus (LCMV) have been isolated from mice, hamsters and humans in the United States, Europe and Japan. Experimentally infected mice exhibit different clinical signs and lethality depending on a combination of LCMV epitope peptides and host major histocompatibility complex (MHC) class I molecules. This study examined the pathogenicity, clinical signs and lethality, of two new LCMV strains (BRC and OQ28) using three inbred mouse strains with different genetic backgrounds having different H-2D haplotypes...

This study examines the accuracy of the Test of Memory Malingering (TOMM), a frequently administered measure for evaluating effort during neurocognitive testing. In the last few years, several authors have suggested that the initial recognition trial of the TOMM (Trial 1) might be a more useful index for detecting feigned or exaggerated impairment than Trial 2, which is the source for inference recommended by the original instruction manual (Tombaugh, 1996). We used latent class modeling (LCM) implemented in a Bayesian framework to evaluate archival Trial 1 and Trial 2 data collected from 1,198 adults who had undergone outpatient forensic evaluations...

Isolated islets used for transplantation are known to be stressed, which can result from the circumstances of death, in particular brain death, the preservation of the pancreas with its warm and cold ischemia, from the trauma of the isolation process, and the complex events that occur during tissue culture. The current study focused upon the events that occur before the islet isolation procedure. Pancreases were obtained from brain dead donors (n = 7) with mean age 50 (11) and normal pancreatic tissue obtained at surgery done for pancreatic neoplasms (n = 7), mean age 69 (9)...

Immune-mediated effector molecules can limit cancer growth, but lack of sustained immune activation in the tumour microenvironment restricts antitumour immunity. New therapeutic approaches that induce a strong and prolonged immune activation would represent a major immunotherapeutic advance. Here we show that the arenaviruses lymphocytic choriomeningitis virus (LCMV) and the clinically used Junin virus vaccine (Candid#1) preferentially replicate in tumour cells in a variety of murine and human cancer models...

Peripheral tolerance is an important mechanism by which the immune system can guarantee a second line of defense against autoreactive T and B cells. One autoimmune disease that is related to a break of peripheral tolerance is diabetes mellitus type 1. Using the RIP-GP mouse model, we analyzed the role of the spleen and lymph nodes (LNs) in priming CD8(+) T cells and breaking peripheral tolerance. We found that diabetes developed in splenectomized mice infected with the lymphocytic choriomeningitis virus (LCMV), a finding showing that the spleen was not necessary in generating autoimmunity...

Studies estimate that 6% to 27% of deaths in hospitals might be prevented with higher quality care. These estimates may be inaccurate because they fail to account for the uncertainty associated with classifying preventability. The purpose of this study was to measure the prevalence of preventable deaths, accounting for the uncertainty in preventability ratings.We created standardized structured case abstracts for all deaths at a multisite academic teaching hospital over a 3-month period. Each case abstract was evaluated independently by 4 reviewers who rated death preventability on a 100-point scale ranging from 0 ("Definitely not preventable") to 100 ("Definitely preventable")...

BACKGROUND: China's lung cancer crude death rate has increased 6.9-fold from 1973 to 2014. During this time, the country experienced extremely rapid economic growth and social change. It is important to understand the effects of risk factors on Lung Cancer Mortality (LCM) for better allocation of limited resources of cancer prevention and control in China. METHODS: Using three nationwide mortality surveys from 1973 to 2005, Global Health Data Exchange data in 2013, three nationwide smoking surveys from 1984 to 2013, four population censuses from 1964 to 2000, and other datasets, we have compiled datasets and developed spatial random effect models to assess the association of various area level contributing factors on LCM...

BACKGROUND: Bile acids (BAs) are steroid molecules that are synthesized in the liver. In addition to their important role as a surfactant in solubilizing lipids and promoting the absorption of lipids in the gastrointestinal tract, they act as inflammagens. The role of BAs and their receptor farnesoid X receptor (FXR) during viral infection has not been studied in detail. METHODS: By using FXR-deficient mice, we investigated the role of bile acid receptor FXR during infection with lymphocytic choriomeningitis virus (LCMV)...
