BACKGROUND: Patients with implanted spinal cord stimulators (SCS) present to the anesthesia care team for management at many different points along the care continuum. Currently, the literature is sparse on the perioperative management. What is available is confusing; monopolar electrocautery is contraindicated but often used, full body magnetic resonance imaging (MRI) is safe with particular systems but with other manufactures only head and specific extremities exams are safe. Moreover, there are anesthetizing locations outside of the operating room where implanted SCS can interact with surrounding medical equipment and pose significant risk to patient and device...

PURPOSE OF REVIEW: Non-motor symptoms in patients with Parkinson's Disease (PD) are better predictors of quality of life changes, caregiver burden, and mortality than motor symptoms. Levodopa has limited, and sometimes detrimental, effects on these symptoms. In this review we discuss recent evidence on pharmacological treatments for non-motor symptoms. RECENT FINDINGS: Breakthroughs have been made in the treatment of psychosis and sleep dysfunction. Pimavanserin has become the first FDA approved drug for PD psychosis...

BACKGROUND: The Ki67 labeling index (LI) is regarded as a significant prognostic marker in ER-positive/HER2-negative breast cancer patients. The expression of PgR has recently been identified as another prognostic marker. In the present study, we investigated the prognostic utilities and most suitable cut-off values for Ki67 and PgR, and evaluated the relationship between Ki67 LI and PgR expression in ER-positive/HER2-negative breast cancer. PATIENTS AND METHODS: In the present study, 177 consecutive Japanese women with ER-positive/HER2-negative invasive carcinoma of no special type who were treated between 2000 and 2001 were enrolled...

Some studies have shown that low frequency stimulation (LFS, most commonly 60 Hz), compared to high frequency stimulation (HFS, most commonly 130 Hz), has beneficial effects, short-term or even long-term, on improving freezing of gait (FOG) and other axial symptoms, including speech and swallowing function, in Parkinson disease (PD) patients with bilateral subthalamic nucleus deep brain stimulation (STN DBS). However, other studies failed to confirm this. It seems not clear what determines the difference in response to LFS...

INTRODUCTION: Health state valuation is a key input in many economic evaluations that inform resource allocation across competing healthcare interventions. Empirical evidence has shown that, in preference elicitation surveys, respondents may value a health state differently if they are aware of the condition causing it ('labeling effects'). This study investigates the impact of including a multiple sclerosis (MS) label for valuation of MS health states. METHODS: Health state values for MS were elicited using two internet-based surveys in representative samples of the UK population ( n = 1702; n = 1788)...

A counter-pressure assisted capillary isotachophoresis method in combination with a sieving matrix and ionic spacer was used to perform in-line fluorescence in situ hybridization (FISH) of bacterial cells. A high concentration of sieving matrix (1.8% w/v HEC) was introduced at one end of the capillary and the bacterial cells were suspended in the spacer electrolyte for injection. Using a 2 min injection with 18 psi counter-pressure, 50% of the cells injected into the capillary were hybridized with the fluorescently labelled oligonucleotide and the excess unhybridized probe was separated from the hybridized cells-probe complexes in a two stage ITP method...

Protein digestion and isotope labeling are two critical steps in proteome quantification. However, the conventional in-solution protocol unavoidably suffers from disadvantages such as time-consuming, low labeling efficiency, and tedious off-line manual operation, which might affect the quantification accuracy, reproducibility and throughput. To address these problems, we developed a fully automated proteome quantification platform, in which an ultra-performance immobilized microreactor (upIMER) with graphene-oxide-modified polymer microspheres as the matrix was developed, to achieve not only the simultaneous protein digestion and 18O labeling, but also the on-line integration with nanoHPLC-ESI MS/MS...

Dystonia, which causes intermittent or sustained abnormal postures and movements, can present in a focal or a generalized manner. In the limbs, focal dystonia can occur in either the upper or lower limbs and may be task-specific causing abnormal motor performance for only a specific task, such as in writer's cramp, runner's dystonia, or musician's dystonia. Focal limb dystonia can be non-task-specific and may, in some circumstances, be associated with parkinsonian disorders. The true prevalence of focal limb dystonia is not known and is likely currently underestimated, leaving a knowledge gap and an opportunity for future research...

Hepatitis C virus (HCV) exists as a lipoprotein-virus hybrid lipoviroparticle (LVP). In vitro studies have demonstrated the importance of apolipoproteins in HCV secretion and infectivity leading to the notion that HCV co-opts the secretion of very-low density lipoprotein (VLDL) for its egress. However, our understanding of the mechanisms involved in virus particle assembly and egress, are still elusive. Biogenesis of VLDL particle occurs in the ER followed by subsequent lipidation in the ER and Golgi. Secretion of mature VLDL particles occurs through the Golgi secretory pathway...

BACKGROUND: Urinary tract infection (UTI) after abdominal solid organ transplantation (SOT) is associated with significant morbidity and mortality. Fosfomycin tromethamine (FOS), a uroselective antibiotic, is FDA approved for uncomplicated UTIs in women and is used off-label for complicated UTIs and prostatitis in men. Literature supporting the use of FOS in the SOT population is limited, and efficacy is questioned in the setting of renal dysfunction. OBJECTIVE: To evaluate the success of FOS for the treatment of cystitis in SOT patients with renal dysfunction...

The side effects of chemotherapy bring significant physical and psychological suffering to patients. To solve this urgent medical problem, Yb(3+) and Er(3+) co-doped NaLuF4 upconversion nanoparticles (UCNPs) were constructed for upconversion luminescence (UCL)-labeled diagnosis under 980 nm laser irradiation. The UCNPs were then modified layer by layer with polypyrrole and a special programming DNA segment as photothermal conversion agents and controllable drug carriers, respectively. The nanoplatform was successfully used for imaging-guided synergistic therapy (photothermal therapy and chemotherapy) at a safe power density (300 mW cm(-2)), and DNA-assisted detoxification at lower temperature in cancer cells when the laser off...

The "Therapeutic Orphan" status of children is gradually improving, but our efforts to eliminate off-label/off-evidence use must be sustained for safer and more effective pediatric drug therapy. This is even more important in resource-scarce settings, because of the increasing child population in those regions. The juncture of pediatric pharmacology and global child health represents an emerging field of clinical pharmacology illuminating a crucial societal need on a global scale.

The Old World (OW) arenavirus Lassa (LASV ) is estimated to infect several hundred thousand people yearly in West Africa, resulting in high numbers of Lassa fever (LF), a viral hemorrhagic fever (HF) disease associated with high morbidity and mortality. To date, no licensed vaccines are available to LASV infections, and anti-LASV drug therapy is limited to an off-label use of ribavirin (Rib) that is only partially effective. The development of reverse genetics has provided investigators with a novel and powerful approach for the investigation of the molecular, cell biology, and pathogenesis of LASV...

PURPOSE: The US Food and Drug Administration (FDA) has approved epoetin and darbepoetin for chemotherapy-induced anemia (CIA). Approved epoetin and darbepoetin dosing schedules were three times per week and weekly, respectively, although off-label, less frequent scheduling was common. In 2004, 2007, and 2008, a US Food and Drug Administration Advisory Committees warned of risks associated with erythropoiesis-stimulating agents. During this period, lawsuits alleging illegal darbepoetin marketing practices have concluded, resulting in $1...

The gustatory system of the sea catfish Plotosus japonicus, like that of other catfishes, is highly developed. To clarify the details of the morphology of the peripheral gustatory system of Plotosus, we used whole-mount immunohistochemistry to investigate the distribution and innervation of the taste buds within multiple organs including the barbels, oropharyngeal cavity, fins (pectoral, dorsal, and caudal), and trunk. Labeled taste buds could be observed in all the organs examined. The density of the taste buds was higher along the leading edges of the barbels and fins; this likely increases the chance of detecting food...
