BACKGROUND: Duchenne muscular dystrophy (DMD) is the most frequent inherited form of muscular dystrophy during childhood. DMD is a severe and progressive disease. Children initially have no symptoms, but the diagnosis is often delayed until the child is about 5 years old. PURPOSE: Although few studies have addressed parent reactions to DMD, parental reactions to other serious childhood conditions have been documented. This study aims to understand the resolution styles that parents use in the context of their children with DMD...

OBJECTIVES: A considerable proportion of regional variation in healthcare use and health expenditures is to date still unexplained. The aim was to investigate regional differences in the gatekeeping role of general practitioners and to identify relevant explanatory variables at patient and district level in Bavaria, Germany. DESIGN: Retrospective routine data analysis using claims data held by the Bavarian Association of Statutory Health Insurance Physicians. PARTICIPANTS: All patients who consulted a specialist in ambulatory practice within the first quarter of 2011 (n=3 616 510)...

BACKGROUND: The Risk Stratification Index and the Hierarchical Condition Categories model baseline risk using comorbidities and procedures. The Hierarchical Condition categories are rederived yearly, whereas the Risk Stratification Index has not been rederived since 2010. The two models have yet to be directly compared. The authors thus rederived the Risk Stratification Index using recent data and compared their results to contemporaneous Hierarchical Condition Categories. METHODS: The authors reimplemented procedures used to derive the original Risk Stratification Index derivation using the 2007 to 2011 Medicare Analysis and Provider review file...

BACKGROUND: A common feature of most reviews or catalogues of health utilities has been their focus on adult health states or derivation of values from adult populations. More generally, utility measurement in or on behalf of children has been constrained by several methodological concerns. The objective of this study was to conduct the first comprehensive systematic review and meta-analysis of primary utility data for childhood conditions and descriptors, and to determine the effects of methodological factors on childhood utilities...

Care management of high-cost/high-needs patients is an increasingly common strategy to reduce health care costs. A variety of targeting methodologies have emerged to identify patients with high historical or predicted health care utilization, but the more pertinent question for program planners is how to identify those who are most likely to benefit from care management intervention. This paper describes the evolution of complex care management targeting strategies in Community Care of North Carolina's (CCNC) work with the statewide non-dual Medicaid population, culminating in the development of an "Impactability Score" that uses administrative data to predict achievable savings...

This study aimed to identify the factors affecting the crash-related severity level of injuries in taxis and quantify the associations between these factors and taxi occupant injury severity. Casualties resulting from taxi crashes from 2004 to 2013 in Hong Kong were divided into four categories: taxi drivers, taxi passengers, private car drivers and private car passengers. To avoid any biased interpretation caused by unobserved spatial and temporal effects, a Bayesian hierarchical logistic modeling approach with conditional autoregressive priors was applied, and four different model forms were tested...

Eun Jong Kong, Hyunjung Lee
Previous research has shown differential degrees of attention in processing hierarchical linguistic information where higher order cues require greater attention in speech processing. The current study investigated the influence of attentional resources on acoustic cue weightings in speech perception by examining Korean listeners' identifications of the three-way laryngeal stops (tense vs. lax vs. aspirated). Using a dual-task paradigm, we presented 28 adult Korean listeners with identification tasks blocked by no-distractor versus distractor conditions where arithmetic calculations distracted the listeners' speech processing...

Yi Lei, Xiuling Liang, Chongde Lin
Although a number of studies have explored the time course of category-based induction, little is known about how the hierarchical levels (superordinate, basic, subordinate) of premises affect category-based induction. The EEG data were recorded when nineteen healthy human participants were performing a simplified category-based induction task. The ERP results showed that: in the subordinate conclusion condition, the basic premise elicited a larger N400, versus the superordinate promise; in the basic conclusion condition, the superordinate promise elicited a larger P300 relative to both the basic premise and subordinate premise; in the superordinate conclusion condition, however, no difference was found between different promise...

Hierarchical association coefficient algorithm calculates the degree of association between observations and categories into a value named hierarchical association coefficient (HA-coefficient) between 0 for the lower limit and 1 for the upper limit. The HA-coefficient algorithm can be operated with stratified ascending categories based on the average of observations in each category. The upper limit refers to a condition where observations are increasingly ordered into the stratified ascending categories, whereas the lower limit refers to a condition where observations are decreasingly ordered into the stratified ascending categories...

In plant cells, either excess or insufficient iron (Fe) concentration triggers stress responses, therefore it is strictly controlled. Proteasome-mediated degradation through ubiquitination of Fe homeostasis proteins has just become the focus of research in recent years. Deactivating ubiquitin ligases, COP9 signalosome has a central importance in the translational control of various stress responses. The aim of the study was to investigate COP9 signalosome in Fe deficiency response of Strategy I plants. In silico analysis of a set of Fe-deficiency-responsive genes was conducted against the transcriptome of Arabidopsis csn mutant lines using Genevestigator software...

BACKGROUND: The burden of serious and persistent mental illness such as schizophrenia is substantial and requires health-care organizations to have adequate risk adjustment models to effectively allocate their resources to managing patients who are at the greatest risk. Currently available models underestimate health-care costs for those with mental or behavioral health conditions. OBJECTIVES: The study aimed to develop and evaluate predictive models for identification of future high-cost schizophrenia patients using advanced supervised machine learning methods...

Few studies have examined rates and causes of short-term readmissions among adults across age and insurance types. We compared rates, characteristics, and costs of 30-day readmission after all-cause hospitalizations across insurance types in the US. We retrospectively evaluated alive patients ≥18 years old, discharged for any cause, 1/1/13-11/31/13, 2006 non-federal hospitals in 21 states in the Nationwide Readmissions Database. The primary stratification variable of interest was primary insurance. Comorbid conditions were assessed based on Elixhauser comorbidities, as defined by administrative billing codes...

In this work, a new category of anionic Gemini surfactants with a rigid space, disodium 2,2'-(1, 4-phenylene bis (methylene)) bis (alkane-1-sulfate) (CmArCm, m=8, 10, 12, 14), were developed. They showed excellent surface activity and remarkable micellization tendency in aqueous solutions as measured by the equilibrium surface tension method. It was noticed that both the surface activity and micellization ability of CmArCm were gradually strengthened upon increasing the hydrophobic chain length m. Those Gemini surfactants were employed as capping reagents to fabricate three-dimensional (3D) hierarchical silver microparticles (AgMPs) successfully even in a large-scale of gram-level...
