AbstractObjectivesThe study aimed to examine whether dissociation and attitudes towards change were associated with the psychopathology in patients with eating disorders (EDs) at 1‐year follow‐up.MethodThe study included 110 females with anorexia nervosa and bulimia nervosa (48 and 62 respectively). At the beginning of the study and 1 year later, they were assessed by means of the following questionnaires: Dissociative Experiences Scale, Attitudes Towards Change (ACTA), State–Trait Anxiety Inventory, Rosenberg Self‐Esteem Scale, Beck Depression Inventory, Eating Attitude Test, Bulimic Investigatory Test Edinburgh and Body Shape Questionnaire (BSQ).ResultsNo statistically significant differences were found between both diagnostic groups regarding dissociation scores. The ACTA at baseline, specifically for patients in the contemplation stage, mediate the effect of dissociation on the psychopathological outcome.DiscussionThese findings suggest that dissociation might be a transdiagnostic feature related to the EDs outcome. The psychotherapeutic framework must take it into account, particularly in patients in the contemplation stage.
A novel double pole transfer function‐single frequency filtering approach for speech enhancement
Authors: Srinivasarao V. , Ghanekar Umesh 
Published: August 2020

AbstractSpeech intelligibility improvement is a major field of recent research with in audiology and hearing domain. Speech signal usually gets affected due to various environmental and background noise. Several approaches for speech intelligibility improvement were presented in the literature. In this paper, a method of speech enhancement based on Double Pole Transfer Function‐Single Frequency Filter (DPTF‐SFF) has been proposed. In the SFF approach the temporal and spectral resolutions are controlled with a one particular value of the filter that corresponds to the pole position in the complex z‐plane. The proposed method uses double pole transfer function SFF that improves the magnitude and phase for various frequencies which are used in the synthesis of the original signal. In the analysis of this method clean speech signals are used from GRID corpus database and noise signals are taken from NOIZEUS and NOISEX‐92 databases. The performance evaluation of this method is carried out in terms of Perceptual Evaluation of Speech Quality, Short‐Time Objective Intelligibility, and Segmental Signal to Noise Ratio metrics. The implementation results proved that the proposed method is an efficient one as it gives higher intelligibility scores compared to the existing methods at different SNR levels (dB) and for different noises employed.
Forecasting US inflation using Markov dimension switching
Authors: Prüser Jan 
Published: August 2020

AbstractThis study considers Bayesian variable selection in the Phillips curve context by using the Bernoulli approach of Korobilis (Journal of Applied Econometrics, 2013, 28(2), 204–230). The Bernoulli model, however, is unable to account for model change over time, which is important if the set of relevant predictors changes. To tackle this problem, this paper extends the Bernoulli model by introducing a novel modeling approach called Markov dimension switching (MDS). MDS allows the set of predictors to change over time. It turns out that only a small set of predictors is relevant and that the relevant predictors exhibit a sizable degree of time variation for which the Bernoulli approach is not able to account, stressing the importance and benefit of the MDS approach. In addition, this paper provides empirical evidence that allowing for changing predictors over time is crucial for forecasting inflation.

AbstractCurrently, platinum is the most widely used catalyst for low temperature proton exchange membrane fuel cells (PEMFC). However, the kinetics at the cathode are slow, and the price of platinum is high. To improve oxygen reduction reaction (ORR) kinetics at the cathode, platinum can be alloyed with rare earth elements, such as yttrium. We report that Pt3Y has the potential to be over 2 times more active for the ORR compared with Pt inside a real fuel cell. We present detailed photoemission analysis into the nature of the sputtered catalyst surface, using synchrotron radiation photoelectron spectroscopy (SRPES) to examine if surface adsorbates or impurities are present and can be removed. Pretreatment removes most of the yttrium oxide in the surface leaving behind a Pt overlayer which is only a few monolayers thick. Evidence of a substochiometric oxide peak in the Y 3d core level is presented, this oxide extends into the surface even after Ar+ sputter cleaning in‐situ. This information will aid the development of new highly active nanocatalysts for employment in real fuel cell electrodes.

AbstractWe examine the impact of changes in real‐time data access fees on price discovery in the crude oil futures market. Specifically, we examine differences in price discovery in the West Texas Intermediate crude oil futures contracts traded on two exchanges around three events corresponding to changes in real‐time data access fees. We document a decrease in price discovery following two events that increase data access costs. These findings are consistent with the theoretical predictions of Cespa and Foucault that increases in data access costs reduce the number of market participants trading on real‐time data and adversely impact price discovery.

AbstractData envelopment analysis (DEA) is a strong analytical tool and methodology for evaluating the relative efficiency of decision‐making units (DMUs). The DEA models require inputs and outputs, which are equipped with precise information. However, the real‐world inputs and outputs are probably so changeable and complicated that cannot be measured accurately. Consequently, this conflict leads to the analysis of uncertain DEA models. This paper aims to analyze the slacks‐based measure (SBM) model in an uncertain environment where the uncertain inputs and outputs are belief degree‐based uncertainty. The belief degree‐based uncertainty is useful for the cases in which no historical information of an uncertain event is available. As a solution methodology, the uncertain SBM model is converted to a crisp form by using three approaches separately: expected value model, expected value and chance‐constrained model, and dependent chance‐constrained model. Additionally, an alternative uncertain model is introduced to reveal differences of DMUs rankings in three crisp methods. Finally, an applied scenario regarding the Iranian banking system is documented to present the new models.
A network analysis of electricity demand and the cryptocurrency markets
Authors: Okorie David I. 
Published: August 2020

AbstractThis article examines the connectedness and information spillover in the Electricity‐Crypto Network (ECN) system. The Bitcoin and Ethereum markets are studied due to the level of electricity demand for active trading and mining in the three leading crypto mining economies (United States, China, and Japan). Among other findings, the leading net transmitter of information is the return of the Bitcoin market while the demand for electricity in the U.S. and Japan are the leading net information receivers in the ECN system. In a nutshell, the return and trading volumes of the cryptocurrency markets are net information transmitters while the markets' volatility and the demand for electricity in the U.S., China, and Japan are net information receivers in the system. As a policy relevance, given the favourable developments in these crypto markets, greener sources of electrical energy are expedient to mitigate emissions while mining these coins. This will reduce the impact of human activities on the climate.
Time‐varying effects and structural change of oil price shocks on industrial output: Evidence from China's oil industrial chain

Published: August 2020

AbstractBased on the output data of the oil industry chain from February 2006 to June 2017, we construct a time‐varying parameter structural vector auto‐regression with stochastic volatility (TVP‐SVAR‐SV) model and specifically analyse the time‐varying effects and structural change of oil price shocks on China's output at each stage of the oil industrial chain. The results show that the effects of oil price shocks on output from upstream to downstream in the oil industrial chain are time‐varying, and the dynamic impacts vary under different lag lengths. The increase in oil price driven by oil demand shocks is the major factor affecting output at each stage of the oil industrial chain. In addition, there is a structural change in the impacts of oil price shocks before and after the international financial crisis. With the decline in external demand and the implementation of policies to expand domestic demand, the responses of China's output at each stage of the oil industrial chain to oil price shocks have decreased significantly since the international financial crisis.

AbstractRecombinant human bone morphogenetic protein 2 (rhBMP‐2) has been widely used in bone tissue engineering to enhance bone regeneration because of its osteogenic inductivity. However, clinical outcomes can vary depending on the scaffold materials used to deliver rhBMP‐2. In this study, 3D‐printed scaffolds with a ratio of 1:1 polycaprolactone and beta‐tricalcium phosphate (PCL/T50) were applied as carriers for rhBMP‐2 in mandibular bone defect models in dog models. Before in vivo application, in vitro experiments were conducted. Preosteoblast proliferation was not significantly different between scaffolds made of PCL/T50 and polycaprolactone alone (PCL/T0) regardless of rhBMP‐2 delivery. However, PCL/T50 showed an increased level of the alkaline phosphatase activity and mineralization assay when rhBMP‐2 was delivered. In in vivo, the newly formed bone volume of the PCL/T50 group was significantly increased compared with that of the PCL/T0 scaffolds regardless of rhBMP‐2 delivery. Histological examination showed that PCL/T50 with rhBMP‐2 produced significantly greater amounts of newly bone formation than PCL/T0 with rhBMP‐2. The quantities of scaffold remaining were lower in the PCL/T50 group than in the PCL/T0 group, although it was not significantly different. In conclusion, PCL/T50 scaffolds were advantageous for rhBMP‐2 delivery as well as for maintaining space for bone formation in mandibular bone defects.

AbstractBackgroundThe frequency and temporal trend in the prevalence of arrhythmias and associated in‐hospital outcomes in patients with sickle cell disease (SCD) have never been quantified.MethodsOur study cohort of SCD patients and sub‐types of arrhythmias were derived from the 2010‐2014 National Inpatient Sample using relevant diagnostic codes. The frequency and trends of arrhythmia and odds of inpatient mortality were measured.ResultsA total of 891 450 hospitalized SCD patients were identified, of which, 55 616 (6.2%) patients experienced arrhythmias. The SCD cohort with arrhythmia demonstrated higher all‐cause mortality (2.7% vs 0.4%; adjusted OR 2.53, 95% CI 2.15‐2.97, P < .001), prolonged hospital stays (6.9 vs 5.0 days) and higher hospital charges ($53 871 vs $30 905) relative to those without arrhythmias (P < .001).The frequency of supraventricular arrhythmia (AFib, SVT, and AF) and ventricular arrhythmia (VFib and VT) were 1893 and 362 per 100 000 SCD‐related admissions, respectively. Unspecified arrhythmias (4126) were seen most frequently followed by AFib (1622) per 100 000 SCD‐related admissions. From 2010 to 2014, the frequency of any arrhythmias and atrial fibrillation in hospitalized SCD patients relatively increased by 29.6% and 38.5%, respectively. There was nearly a twofold (2.4% in 2010 to 5.0% in 2014) increase in the frequency of arrhythmia among patients aged <18 years. The frequency of arrhythmias in hospitalized male and female SCD patients relatively increased by 28.8% and 31.4%, respectively (Ptrend < .001).ConclusionsThe frequency of arrhythmias among SCD patients is on the rise with worse hospitalization outcomes, including higher in‐hospital mortality and higher resource utilization as compared to those without arrhythmias.

AbstractBackgroundPatients with intestinal failure (IF) are dependent on parenteral nutrition (PN), however, they are at risk of central line–associated bloodstream infections (CLABSIs) and line complications. Four‐percent tetrasodium ethylenediaminetetraacetic acid (EDTA) solution is an effective nonantibiotic, antimicrobial, antibiofilm, and anticoagulant agent. Our objective was to determine 4% tetrasodium EDTA efficacy in preventing CLABSIs and reducing line occlusions in pediatric IF patients.MethodsWe conducted a retrospective cohort study of patients managed at 2 tertiary Canadian pediatric centers between April 2016 and December 2018 who received 4% tetrasodium EDTA solution under the brand name Kitelock. Data were collected for 12 months pre and post‐Kitelock. CLABSIs and alteplase administration were compared using a Wilcoxon matched‐pairs signed‐rank test. Data were reported as medians and frequencies.ResultsTwenty patients were included (10 boys; median age, 83 months [range, 8–232 months]). The rate of CLABSIs before 4% tetrasodium EDTA was 2.7+4 per 1000 catheter days. Patients received 4% tetrasodium EDTA for a median of 365 (278–365) days, with no infections in the 12 months post‐therapy (P = .002). Median rates of occlusive episodes for the entire cohort before 4% tetrasodium EDTA were 0 (0–5.0) and 0 (0–2.0) after starting therapy (P = .018). In patients with previous occlusions (n = 9), the median episodes of alteplase use previously was 5.5 (2.7–19.2) compared with 2.7 (0–2.7) (P = .018).ConclusionsOur preliminary findings suggest 4% tetrasodium EDTA solution is effective in reducing CLABSIs and catheter occlusions in pediatric patients with long‐term central‐access.

AbstractBackgroundPeri‐implant disease (PID) has not been directly linked to pathological organ changes. The present study assessed the dynamics of serum biochemical parameters in a model of experimental peri‐implantitis in dogs, followed by open flap debridement.MethodsSeven male beagle dogs comprised the study group. Procedures were performed as follows—extractions of two premolars and one molar on each mandibular quadrant (Day 0); bone healing time (week14); placement of four rough‐surface endoosseous implants, two on each mandibular side; implant uncovering (week 28); induction of experimental peri‐implantitis by the use of three ligatures (weeks 31, 34, 37) followed by open flap debridement (week 42). Serum biochemical analysis following each procedure was compared to baseline. Biochemical parameters were assigned into four subsets of variables—inflammation, renal function, liver function, and blood glucose. Wilcoxon paired tests were conducted in order to identify statistically significant differences between baseline data and values obtained after each procedureResultsFollowing experimental peri‐implantitis, the dynamics of renal parameters and blood glucose were minimal whereas statistically significant (P < 0.05) increases were noted for inflammatory (total protein and albumin concentrations) and hepatic (ALT, AST) parameters. A statistically significant (P < 0.05) decrease was only noted for total bilirubin. After open flap debridement, inflammatory (total protein and albumin concentrations) and hepatic (AST) parameters returned to baseline.ConclusionsWithin their limits, the present results indicate that: (a) PID affects inflammatory and hepatic serum biochemical parameters, and (b) following open flap debridement most of the values returned to baseline.

Published: August 2020

AbstractBACKGROUNDSeafood parasitation by Anisakis (Anisakidae) larvae has been reported in most of the oceans and seas worldwide. The presence of these nematodes in commonly consumed fish represents a potential hazard for consumers as they can provoke gastrointestinal symptoms and allergic reactions. In the present work, the capacity of a SYBR Green qPCR protocol to quantify Anisakis larvae in commercial fish was evaluated using experimentally spiked samples with different numbers (0–50) of A. simplex third‐stage larvae (L3). To verify the agreement of the obtained results, 25 naturally infected fish specimens of Atlantic blue whiting underwent a parallel visual inspection.RESULTSThe logarithmic behavior of the Cq data obtained from the experimentally spiked samples allowed the development of a descriptive mathematical model that correlates the Cq value with the number of Anisakis larvae (R2 = 0.9908, CV = 2.37%). In the commercial blue whiting specimens there was a high correlation between the results of the molecular technique and the visual inspection (R2 = 0.9912); the Bland–Altman analysis showed that 94% of the differences were within the limits of agreement (−4.98 and 6.68), indicating the reliability of the descriptive mathematical model based on the SYBR Green qPCR technique.CONCLUSIONThe descriptive function presented based on the SYBR Green qPCR assay is promising as a sensitive and accurate tool for measuring the Anisakis larval load in commercial fish, with a potential application not only in the food industry but also in prevention programs for public health. © 2020 Society of Chemical Industry

Published: August 2020

ObjectiveDetection of fetal airway compromise through imaging raises the possible need for ex utero intrapartum treatment (EXIT) procedures. Despite EXIT procedures involving massive resource utilization and posing increased risk to the mother, decisions for EXIT are usually based on anecdotal experience. Our objectives were to analyze prenatal consultations with potential fetal airway obstruction for imaging and obstetric findings used to determine management strategy.MethodsRetrospective chart review was performed for prenatal abnormal fetal airway consults between 2004–2019 at a quaternary pediatric facility. Data collected included demographics, imaging characteristics, delivery information, and airway management. Our primary outcome was EXIT performance and the secondary outcome was postnatal airway management. Fisher's exact test was used to compare management decisions, outcomes, and imaging findings.ResultsThirty‐seven patients met inclusion criteria. The most common diagnoses observed were lymphatic malformation, teratoma, and micrognathia. Of the imaging findings collected, only midline neck mass location was associated with EXIT procedure performance. Factors associated with invasive airway support at birth were mass‐induced in‐utero neck extension and neck vessel compression, polyhydramnios, and micrognathia.ConclusionsMultidisciplinary input and interpretation of prenatal imaging can guide management of fetal airway‐related pathology. EXIT is an overall safe procedure and can decrease risk due to airway obstruction at birth. We identified in‐utero neck extension, neck vessel compression, micrognathia, and polyhydramnios as better indicators of a need for invasive airways measures at birth and suggest use of these criteria in combination with clinical judgement when recommending EXIT.Level of Evidence4 Laryngoscope, 131:E1357–E1362, 2021

AbstractLipid composition of liposomal bilayer should alter the cell response for permeability, transport, and uptake in small intestine. This work was done to investigate the transport and uptake of liposomes composed of docosahexaenoic acid‐enriched phosphatidylcholine (PtdCho), phosphatidylserine (PtdSer), and sulfoquinovosyl diacylglycerol (SQDG) derived from marine products on multilamellar vesicles (MLV) in small intestinal epithelial cell models. The results showed that addition of PtdSer and SQDG as liposomal bilayer could improve the efficiency entrapment of liposomes. The liposomes containing PtdSer showed higher transport and uptake through both Caco‐2 cell and M cell monolayers as compared to PtdCho‐MLV. SQDG‐containing liposomes exhibited only higher transport through M cell monolayer, while its uptake effect was higher both in Caco‐2 cell and M cell monolayers. The results of experiments done with endocytosis inhibitors indicated that PtdCho‐MLV must be transported via macropinocytosis and uptaken by phagocytosis in M cell monolayer model. PtdCho/PtdSer‐MLV and PtdCho/SQDG‐MLV might be transported and uptaken through M cell monolayer by phagocytosis. The result also indicated that PtdCho/SQDG‐MLV could open the tight junction of small intestinal epithelial cell monolayers. Furthermore, our findings demonstrated that the surface status of cholesterol‐containing liposomes were smooth, but they did not affect their transport and uptake through Caco‐2 cell and M cell monolayers.
