PURPOSE: Hospital transfers may affect clinical outcomes. Evaluation of admission by source of transfer, time of admission, and provider type may identify opportunities to improve inpatient outcomes. METHODS: We reviewed charts of patients admitted to the solid tumor oncology service between July and December 2014 from the Cleveland Clinic Foundation (CCF) Main Campus emergency department (ED), CCF Regional EDs, outside hospital (OSH) ED, OSH inpatient services, and CCF outpatient clinics...

The charge transfer kinetics of lithium ion intercalation into LixMn2O4 cathode materials was examined in dilute and concentrated aqueous and carbonate LiTFSI solutions using electrochemical methods. Distinctive trends in ion intercalation rates were observed between water-based and ethylene carbonate/diethyl carbonate solutions. The influence of the solution concentration on the rate of lithium ion transfer in aqueous media can be tentatively attributed to the process associated with Mn dissolution, while in carbonate solutions the rate is influenced by the formation of a concentration-dependent solid electrolyte interface (SEI)...

OVERVIEW: Though not an official diagnosis, psychopathy has become an important area of research due to the litany of deleterious outcomes associated with this aspect of temperament. Psychopathy is composed of primary and secondary traits. Research consistently links psychopathy to alcohol pathology, though often only via secondary traits which are comprised of intractable aspects of behavior (e.g., poor impulse control). In contrast, primary psychopathy is comprised of behaviors that can be learned and thus may be more malleable (i...

In vitro technologies provide the capacity to study drug metabolism where in vivo studies are precluded due to ethical or financial constraints. The metabolites generated by in vitro studies can assist anti-doping laboratories to develop protocols for the detection of novel substances that would otherwise evade routine screening efforts. In addition, professional bodies such as the Association of Official Racing Chemists (AORC) currently permit the use of in vitro derived reference materials for confirmation purposes providing additional impetus for the development of cost effective in vitro metabolism platforms...

Renal Supportive Care is an alternative treatment pathway in advanced Chronic Kidney Disease (CKD) that is being increasingly adopted, particularly in the elderly. RSC utilises principles of palliative care and has been developed to enhance the care for dialysis patients with a high symptom burden and those being managed on a non-dialysis pathway. Nutrition management is often an under-recognised component of care, and can play an important role in improving patients' quality of life to reduce symptom burden, support physical function and independence and provide appropriate counselling to patients and their families to ensure the goals of RSC are met...

Among the enzymes involved in the post-translational modification of Ras, isoprenyl carboxyl methyltransferase (ICMT) has been explored by a number of researchers as a significant enzyme controlling the activation of Ras. Indeed, inhibition of ICMT exhibited promising anti-cancer activity against various cancer cell lines. This paper reviews patents and research articles published between 2009 and 2016 that reported inhibitors of ICMT as potential chemotherapeutic agents targeting Ras-induced growth factor signaling...

Obesity prevention efforts may be ineffective if parents lack awareness of their children's overweight status. This study examined the factors that predicted parents' underestimation of child weight status. Using a cross sectional design, researchers recruited children and parents in a local children's museum. Parents completed a demographic questionnaire, the Newest Vital Sign, and the Child Body Image Scale. Children's height and weight were measured to calculate child BMI. Random effects modeling examined the association between predictor variables (parent race/ethnicity, income, education, and health literacy, and child BMI percentile, gender, and age) and the dependent variable, parent underestimation of child weight status...

State boards of pharmacy are generally responsible for the governance of the practice of pharmacy. While the regulatory process and methods for accomplishing this task may vary by state, all boards of pharmacy must address medication errors committed by pharmacists. The National Association of Boards of Pharmacy (NABP) has recommended that state boards of pharmacy implement best practices and enforcement actions that are aimed to promote patient safety and reduce medication errors. The current study was designed to identify and compare current corrective action practices among boards of pharmacy in response to medication errors...

INTRODUCTION: Cigarette smoking is one of the leading causes of early death in the UK and worldwide. Public health guidance recommends the use of varenicline, bupropion and nicotine replacement therapy (NRT) as smoking cessation aids in the UK. Additionally, the first electronic cigarette has been licensed for use as a smoking cessation medicine. However, there are ongoing concerns about the safety of these medicines. We present a protocol for a systematic review and network meta-analysis (NMA) to determine how these smoking cessation medicines compare to each other with respect to their neuropsychiatric safety in adult smokers...

We describe the observation of GW170104, a gravitational-wave signal produced by the coalescence of a pair of stellar-mass black holes. The signal was measured on January 4, 2017 at 10∶11:58.6 UTC by the twin advanced detectors of the Laser Interferometer Gravitational-Wave Observatory during their second observing run, with a network signal-to-noise ratio of 13 and a false alarm rate less than 1 in 70 000 years. The inferred component black hole masses are 31.2_{-6.0}^{+8.4}M_{⊙} and 19.4_{-5.9}^{+5...

The Nudged Elastic Band (NEB) algorithm is the leading method of calculating transition states in chemical systems. However, the current literature lacks adequate guidance for users wishing to implement a key part of NEB, namely, the optimization method. Here, we provide details of this implementation for the following six gradient descent algorithms: Steepest Descent, Quick-Min Verlet, FIRE, Conjugate Gradient, Broyden-Fletcher-Goldfarb-Shanno (BFGS) and Limited-memory BFGS (LBFGS). We also construct and implement a new, accelerated backtracking line search method in concert with a partial Procrustes superimposition to improve upon existing methods...

Antimicrobials are widely used in veterinary practices, but there has been no investigation into the classes of antimicrobials used or the appropriateness of their use in surgical prophylaxis. Antimicrobial usage guidelines were published by the Australian Infectious Disease Advisory Panel (AIDAP) in 2013, but there has been no investigation of compliance with them. This study aimed to investigate antimicrobial use for surgical prophylaxis in companion animal practice and assess compliance with AIDAP guidelines for selected conditions by conducting a cross-sectional study of antimicrobial usage patterns of Australian veterinarians using an online questionnaire...

A theory is presented for the upper bound on the mean time τ to the detection of an undersea acoustic communications network by an energy detector whose initial position and heading are uniformly distributed random variables. The network is an infinite square grid of omnidirectional transmit-receive nodes on a flat bottom. Each node transmits to one nearest neighbor at a bit-rate R equal to Shannon's capacity, maximizing τ. The network sets a signaling bandwidth W and node-spacing D. The detector sets a false-alarm rate, integration time, height above the bottom, and speed...

BACKGROUND: Alcohol use disorders are associated with dysfunctional social relationships and stress responses. The neuropeptides oxytocin (OT) and vasopressin (AVP) are known to orchestrate or mediate many aspects of social behavior, stress responses, and ingestive behaviors. Because of the overlap between the effects of alcohol and the roles of oxytocin and vasopressin, we sought to determine if alcohol consumption altered expression of OT and AVP in the paraventricular nucleus of the hypothalamus (PVN), one of the key sites for OT and AVP synthesis...

It is often assumed that LBD generates more information than can be reasonably examined. METHODS: We present a detailed analysis of the quantity of hidden knowledge produced by an LBD system and the effect of various filtering approaches upon this. The investigation of filtering combined with single or multi-step linking term chains is carried out on all articles in PubMed...

Human and animal data suggest that the hippocampus plays certain roles in regulating food intake. However, its actual role may be far broader than currently envisaged, a claim suggested by the centrality of the hippocampus to so many aspects of human/animal cognition. Understanding these ingestion-related functions is especially significant. This is because some degree of hippocampal impairment may be quite common, resulting for example from a Western-style diet, insomnia, diabetes, and depression-among many other causes...

Background: The first models of malaria transmission assumed a completely mixed and homogeneous population of parasites.  Recent models include spatial heterogeneity and variably mixed populations. However, there are few empiric estimates of parasite mixing with which to parametize such models. Methods: Here we genotype 276 single nucleotide polymorphisms (SNPs) in 5199 P. falciparum isolates from two Kenyan sites and one Gambian site to determine the spatio-temporal extent of parasite mixing, and use Principal Component Analysis (PCA) and linear regression to examine the relationship between genetic relatedness and relatedness in space and time for parasite pairs...
