BACKGROUND: Organizations such as the National Comprehensive Cancer Network, American Society of Clinical Oncology, Institute for Clinical and Economic Review, and Memorial Sloan Kettering have created distinct tools to help different stakeholders assess the value of oncology treatments. However, the oncology value tools were not necessarily created for payers, and it is unclear whether payers are using these tools as part of their drug management process. OBJECTIVE: To understand what value tools payers are using in oncology management and what benefits and shortcomings the tools may have from the payer perspective...

Feng He, Lin Zhao, Ershuai Li
Ethernet-AVB/TSN (Audio Video Bridging/Time-Sensitive Networking) and AFDX (Avionics Full DupleX switched Ethernet) are switched Ethernet technologies, which are both candidates for real-time communication in the context of transportation systems. AFDX implements a fixed priority scheduling strategy with two priority levels. Ethernet-AVB/TSN supports a similar fixed priority scheduling with an additional Credit-Based Shaper (CBS) mechanism. Besides, TSN can support time-triggered scheduling strategy. One direct effect of CBS mechanism is to increase the delay of its flows while decreasing the delay of other priority ones...

Barak Shapira, Alina Poperno, Ronny Berkovitz
This article represents a short review of the current knowledge on the abuse of synthetic cannabinoids from the perspective of the Division of Enforcement and Inspection of the Israeli Ministry of Health - a body in charge of providing professional assistance to law enforcement bodies in the fields of drug abuse. We describe the principal changes observed in the synthetic cannabinoid market and the Israeli legislators' and enforcement bodies' attempts to cope with these phenomena. These changes relate to the types of synthetic cannabinoids being trafficked, with many structural variations between substances, and a new legal framework which allows for the rapid, temporary scheduling of synthetic cannabinoids using both individual and generic definitions...

REVIEW
Marc S Halfon
Animal development proceeds through the activity of genes and their cis-regulatory modules (CRMs) working together in sets of gene regulatory networks (GRNs). The emergence of species-specific traits and novel structures results from evolutionary changes in GRNs. Recent work in a wide variety of animal models, and particularly in insects, has started to reveal the modes and mechanisms of GRN evolution. I discuss here various aspects of GRN evolution and argue that developmental system drift (DSD), in which conserved phenotype is nevertheless a result of changed genetic interactions, should regularly be viewed from the perspective of GRN evolution...

OBJECTIVE: Teduglutide is an active, glucagon-like peptide (GLP)-2 analog with proven clinical efficacy regarding intestinal adaptation in patients with short bowel syndrome (SBS). There are two factors that preclude its reimbursement, and thereby, its availability: its cost (reaching ∼$300,000/y)-which significantly exceeds the cost of home parenteral nutrition (HPN) in most countries-and the lack of clear guidelines. The aim of this study was to create evidence-based working criteria for the use of teduglutide that could be used in clinical settings...

Jia Tian, Li Du
BACKGROUND: A violent attack on medical staff in Guangdong Province, in which a female doctor at Longmen County People's Hospital (LCPH) was severely injured by a knife-wielding patient, has drawn significant public attention to the phenomenon of hospital violence and initiated discussions on how to resolve violence in hospitals. Social networking sites, such as Sina Weibo, a Chinese version of Twitter, have played a role in this public debate. The incident at LCPH provides an opportunity to examine how Weibo has been used in the debate about violence against medical staff in China...

We consider self-tolerance and its failure -autoimmunity- in a minimal mathematical model of the idiotypic network. A node in the network represents a clone of B-lymphocytes and its antibodies of the same idiotype which is encoded by a bitstring. The links between nodes represent possible interactions between clones of almost complementary idiotype. A clone survives only if the number of populated neighbored nodes is neither too small nor too large. The dynamics is driven by the influx of lymphocytes with randomly generated idiotype from the bone marrow...

Background Cost-of-illness (CoI) studies are important instruments for estimating the socioeconomic burden of specified diseases. CoI studies provide important information about the cost structure of a disease, the resulting research need, approaches to improve aspects of care and, monetary consequences from different perspectives. This information can be useful for healthcare research and health policy. Due to heterogeneity of available Cost-of-Illness studies, the working group 'Health Economics' of the German Network for Healthcare Research (DNVF) in accordance with the German Society for Health Economics (DGGÖ) developed an instrument for the planning, conduct and assessment of CoI studies...

Evaluating the genetic contribution of individuals to population structure is essential to select informative individuals for genome sequencing, genotype imputation and to ascertain complex population structures. Existing methods for the selection of informative individuals for genomic imputation solely focus on the identification of key ancestors, which can lead to a loss of phasing accuracy of the reference population. Currently many methods are independently applied to investigate complex population structures...

Understanding the dynamics of human liver metabolism is fundamental for effective diagnosis and treatment of liver diseases in general and the metabolism of drugs in particular. This knowledge can be obtained with systems biology/medicine approaches that account for the complexity of hepatic responses and their systemic consequences in other organs. Computational modelling can reveal hidden principles of the system by classification of individual components, analysing their interactions and simulating the effects that are difficult to investigate experimentally...

Spin crossover (SCO) materials, revealing the externally tunable transition between two different spin states, arouse great scientific interest due to their perspective application in information storage, display devices and sensing. Of special importance are the molecular systems offering the possibility of multimodal switching within many spin centers. This is achievable in polynuclear clusters consisting of several SCO-active complexes, however, such molecules are very rare. Herein, we report a unique pair of nanometric pentadecanuclear {Fe9[M(CN)8]6(Me3tacn)8}·14MeOH (Me3tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane, M = Re, 1; M = W, 2) clusters exhibiting a thermally induced spin crossover effect on Fe(ii) complexes, that is on both central and external Fe sites embedded in the cyanido-bridged cluster core...

Sarangam Majumdar, Sukla Pal
Bacteria are far more intelligent than we can think of. They adopt different survival strategies to make their life comfortable. Researches on bacterial communication to date suggest that bacteria can communicate with each other using chemical signaling molecules as well as using ion channel mediated electrical signaling. Though in past few decades the scopes of chemical signaling have been investigated extensively, those of electrical signaling have received less attention. In this article, we present a novel perspective on time-sharing behavior, which maintains the biofilm growth under reduced nutrient supply between two distant biofilms through electrical signaling based on the experimental evidence reported by Liu et al...

Speech is a complex oral motor function that involves multiple articulators that need to be coordinated in space and time at relatively high movement speeds. How this is accomplished remains an important and largely unresolved empirical question. From a coordination dynamics perspective, coordination involves the assembly of coordinative units that are characterized by inherently stable coupling patterns that act as attractor states for task-specific actions. In the motor control literature, one particular model formulated by Haken et al...

BACKGROUND: African American/Black and Hispanic persons living with HIV (AABH-PLWH) are under-represented in AIDS clinical trials (ACTs) in the United States. Barriers AABH-PLWH experience to ACTs are multi-faceted, including distrust of medical research, low levels of knowledge, unsupportive social norms, lack of referral, and challenges navigating ACT systems. In past research we found a multi-component peer-driven intervention was efficacious in boosting rates of screening for/enrollment into ACTs...

Emerging evidence suggests that the variations in the ability to navigate through any real or virtual environment are accompanied by distinct underlying cortical activations in multiple regions of the brain. These activations may appear due to the use of different frame of reference (FOR) for representing an environment. The present study investigated the brain dynamics in the good and bad navigators using Graph Theoretical analysis applied to low-density electroencephalography (EEG) data. Individual navigation skills were rated according to the performance in a virtual reality (VR)-based navigation task and the effect of navigator's proclivity towards a particular FOR on the navigation performance was explored...

Skeletal muscle is a heterogeneous tissue that represents between 30 and 38% of the human body mass and has important functions in the organism, such as maintaining posture, locomotor impulse, or pulmonary ventilation. The genesis of skeletal muscle during embryonic development is a process controlled by an elaborate regulatory network combining the interplay of extrinsic and intrinsic regulatory mechanisms that transform myogenic precursor cells into functional muscle fibers through a finely tuned differentiation program...

In this paper, we propose a model where two strains compete with each other at the expense of common susceptible individuals on heterogeneous networks by using pair-wise approximation closed by the probability-generating function (PGF). All of the strains obey the susceptible-infected-recovered (SIR) mechanism. From a special perspective, we first study the dynamical behaviour of an SIR model closed by the PGF, and obtain the basic reproduction number via two methods. Then we build a model to study the spreading dynamics of competing viruses and discuss the conditions for the local stability of equilibria, which is different from the condition obtained by using the heterogeneous mean-field approach...
