BACKGROUND: Idiopathic intracranial hypertension (IIH) is characterized by increased cerebrospinal fluid (CSF) pressure and normal or slit ventricles. Lumboperitoneal shunting had been favored by many investigators for CSF diversion in IIH for decades; however, it has been associated with various side effects. Because of the small ventricular size adequate positioning of a ventricular catheter is challenging. OBJECTIVES: Here, we investigated the usefulness of electromagnetic (EM)-guided ventricular catheter placement for ventriculoperitoneal shunting in IIH...

BACKGROUND: Chronic antiplatelet therapy in the post-acute phase of non-cardioembolic ischemic stroke is limited by the risk of intracranial hemorrhage (ICH) complications. METHODS: We developed an ICH risk score based on the PERFORM trial cohort (n = 19,100), which included patients with a non-cardioembolic ischemic stroke or transient ischemic attack, and externally validated this score in one contemporary trial of very similar size and inclusion criteria, the PRoFESS trial (n = 20,332 patients)...

While positron emission tomography (PET) studies have provided invaluable data on antipsychotic effects, selection bias remains a serious concern. A systematic review of PET studies that measured dopamine D2 receptor blockade with antipsychotics was conducted to examine their inclusion/exclusion criteria, using PubMed, EMBASE, and ClinicalTrials.gov (last search, September 2016). PET studies were included if they measured D2 receptor occupancy in patients with schizophrenia and included introduction of antipsychotic treatment or antipsychotic regimen change in a systematic manner...

Detecting, imaging and sizing defects in a bounded elastic medium is still a difficult task, especially when access is complex. Adjoint methods simplify the task as they take advantage of prior information such as the geometry and material properties. However, they still reveal a number of important limitations. Artifacts observed on the conventional topological energy image result from wave interactions with the boundaries of the inspected medium. The paper describes a method for addressing these artifacts, which involves forward and adjoint fields specified in terms of the boundary conditions...

BACKGROUND: Severe fever with thrombocytopenia syndrome (SFTS), an emerging infectious disease caused by a novel bunyavirus, was discovered in rural areas of Central China in 2009. METHODS: A case-control study based on hospital data was applied to detect the potential risk sources for SFTS in SFTS-endemic counties in Hubei Province. Cases were defined as hospitalized SFTSV confirmed patients. Controls were randomly selected from non-SFTSV patients in the same hospital ward within 2 weeks of inclusion of the cases, and they were matched by age (+/- 5 years) and gender according to 1:2 matching condition...

OBJECTIVE: pre-morbid patient conditions and hospitalization complications possibly play a role in status epilepticus short-term outcome, although evidence is incomplete and non-conclusive. The study's aim was to define whether comorbidities and in-hospital complications arising after status epilepticus affect its prognosis. METHODS: A retrospective single center study was carried out. All selected patients were adults presenting an EEG-proven status epilepticus episode between 2003 and 2014...

Abrin, a type II ribosome inactivating protein from the Abrus precatorius plant, is extremely toxic. It has been shown to be 75 times more potent than its infamous sister toxin, ricin and their potential use in bio-warfare is a cause of major concern. Although several vaccine candidates are under clinical trials for ricin, none are available against abrin. The present study proposes a chimeric protein, comprising of 1-123 amino acids taken from the A chain of abrin and 124-175 amino acids from Abrus precatorius agglutinin A chain, as a vaccine candidate against abrin intoxication...

Resveratrol (RESV) is a natural polyphenolic compound endowed with anti-inflammatory, anti-proliferative, as well as pro-apoptotic activities that make it a potential anti-tumor compound. Here we show that RESV counteracts the TGF-β-induced Epithelial to Mesenchymal Transition (EMT) phenotype in mammary gland cells and affects the alternative exon usage of pre-mRNAs that encode crucial factors in adhesion and migration -including CD44, ENAH, and FGFR2- in a panel of immortalized and transformed mammary gland cells...

Administration of sodium salicylate (SS) to cows in early lactation has a positive effect on whole-lactation milk production but a negative effect on metabolism in some cases. The objective of this trial was to determine whether SS directly affects rumen fermentation. Experiment 1 was designed to investigate the effects of direct inclusion of SS in a 24-h batch culture, and experiment 2 was designed to test the fermentative ability of rumen fluid from heifers who had received SS. In experiment 1, we combined strained and pooled rumen fluid from 3 heifers in a 2:1 ratio with McDougall's buffer, and added 150 mL of the inoculum to each flask (n = 5/treatment) with 2...

BACKGROUND: Cervical cancer (CC) occupies fourth place in cancer incidence and mortality worldwide in women, with 560,505 new cases and 284,923 deaths per year. Approximately, nine of every ten (87%) take place in developing countries. When a macroscopic nodal involvement is discovered during a radical hysterectomy (RH), there is controversy in the literature between resect macroscopic lymph node compromise or abandonment of the surgery and sending the patient for standard chemo-radiotherapy treatment...

BACKGROUND: Chronic inguinodynia (groin pain) is a common complication following open inguinal hernia repair or a Pfannenstiel incision but may also be experienced after other types of (groin) surgery. If conservative treatments are to no avail, tailored remedial surgery, including a neurectomy and/or a (partial) meshectomy, may be considered. Retrospective studies in patients with chronic inguinodynia suggested that spinal anaesthesia is superior compared to general anaesthesia in terms of pain relief following remedial operations...

BACKGROUND: Initially known as the reproductive hormone, relaxin was shown to possess other therapeutically useful properties that include extracellular matrix remodeling, anti-inflammatory, anti-ischemic and angiogenic effects. All these findings make relaxin a potential drug for diverse medical applications. Its precursor, pro-relaxin, is an 18 kDa protein, that shows activity in in vitro assays. Since extraction of relaxin from animal tissues raises several issues, prokaryotes and eukaryotes were both used as expression systems for recombinant relaxin production...

This study develops a Bayesian spatial random parameters Tobit model to analyze crash rates on road segments, in which both spatial correlation between adjacent sites and unobserved heterogeneity across observations are accounted for. The crash-rate data for a three-year period on road segments within a road network in Florida, are collected to compare the performance of the proposed model with that of a (fixed parameters) Tobit model and a spatial (fixed parameters) Tobit model in the Bayesian context. Significant spatial effect is found in both spatial models and the results of Deviance Information Criteria (DIC) show that the inclusion of spatial correlation in the Tobit regression considerably improves model fit, which indicates the reasonableness of considering cross-segment spatial correlation...
