The role of sample collection timing on interleukin-6 levels in early-onset neonatal sepsis.

OBJECTIVE To assess different perinatal findings and sample collection timing in newborns with early-onset sepsis comparing those with low IL-6 levels to the ones with high levels. METHODS Eighty-five newborn infants, with clinical signs of sepsis and/or positive blood cultures, had plasma IL-6 collected in the initial evaluation for early-onset sepsis in the first 96 hours of life. They were classified in two groups according to their plasma IL-6 levels: higher, and equal to or lower than IL-6 median value for the whole septic group. RESULTS Median IL-6 for the whole group was 89 pg/ml. High and low level groups were formed by 42 and 43 newborns respectively. There were no differences between the two groups regarding gestational ages, birth weights, cesarean-section proportion, Apgar scores, number of neonates with maternal risk factors for infection, number of maternal intrapartum antibiotic therapy, and number of positive blood cultures. Median plasma IL-6 in the high level group was 287 pg/ml, and in the low level group 46 pg/ml (p < 0.001). Median sample timing was 17.5 hours of life for the high level group and 36 hours of life for the low level group (p < 0.001). There was a significant negative correlation coefficient between IL-6 levels and sample collection timing. CONCLUSION Sample collection timing is an important factor for detection of high plasma IL-6 level in newborn infants with early-onset sepsis.

Bereavement theory: recent developments in our understanding of grief and bereavement

Abstract In recent decades research evidence on the experience of grief has led to a broadening of attention from the traditional focus on an emotional journey from distress to ‘recovery’. This article looks at how early stage theories of grief came to be rejected and examines more recent theories which also consider the cognitive, social, cultural and spiritual dimensions of grief and loss. It goes on to highlight emerging trends in bereavement theory, potential complications of grief, and the evidence for the efficacy of grief interventions.
Designing a social-broadcasting-based business intelligence system

The rise of social media has fundamentally changed the way information is produced, disseminated, and consumed in the digital age, which has profound economic and business effects. Among many different types of social media, social broadcasting networks such as Twitter in the U.S. and “Weibo” in China are particularly interesting from a business perspective. In the case of Twitter, the huge amounts of real-time data with extremely rich text, along with valuable structural information, makes Twitter a great platform to build Business Intelligence (BI) systems. We propose a framework of social-broadcasting-based BI systems that utilizes real-time information extracted from these data with text mining techniques. To demonstrate this framework, we designed and implemented a Twitter-based BI system that forecasts movie box office revenues during the opening weekend and forecasts daily revenue after 4 weeks. We found that incorporating information from Twitter could reduce the Mean Absolute Percentage Error (MAPE) by 44% for the opening weekend and by 36% for total revenue. For daily revenue forecasting, including Twitter information into a baseline model could reduce forecasting errors by 17.5% on average. On the basis of these results, we conclude that social-broadcasting-based BI systems have great potential and should be explored by both researchers and practitioners.
People’s Financial Choice Depends on their Previous Task Success or Failure

Existing knowledge about the impact of the experience prior to financial choices has been limited almost exclusively to single risky choices. Moreover, the results obtained in these studies have not been entirely consistent. For example, some studies suggested that the experience of success makes people more willing to take a risk, while other studies led to the opposite conclusions. The results of the two experimental studies presented in this paper provide evidence for the hypothesis that the experience of success or failure influences people’s financial choices, but the effect of the success or failure depends on the type of task (financial and non-financial) preceding a financial decision. The experience of success in financial tasks increased participants’ tendency to invest and make risky investment choices, while it also made them less prone to save. On the other hand, the experience of failure heightened the amount of money that participants decided to save, and lowered their tendency to invest and make risky investment choices. However, the effects of the experience of success or failure in non-financial tasks were exactly the opposite. The presented studies indicated the role of the specific circumstances in which the individual gains the experience as a possible way to explain the discrepancies in the results of studies on the relationship between the experience prior to financial choice with a tendency to take risks.
Genetic programming for the identification of nonlinear input-output models

Linear-in-parameters models are quite widespread in process engineering, e.g., nonlinear additive autoregressive models, polynomial ARMA models, etc. This paper proposes a new method for the structure selection of these models. The method uses genetic programming to generate nonlinear input−output models of dynamical systems that are represented in a tree structure. The main idea of the paper is to apply the orthogonal least squares (OLS) algorithm to estimate the contribution of the branches of the tree to the accuracy of the model. This method results in more robust and interpretable models. The proposed approach has been implemented as a freely available MATLAB Toolbox, www.fmt. veim.hu/softcomp. The simulation results show that the developed tool provides an efficient and fast method for determining the order and structure for nonlinear input−output models.
Dominant-negative Inhibitors of the Clostridium perfringens ϵ-Toxin*

The Clostridium perfringens ϵ-toxin is responsible for a severe, often lethal intoxication. In this study, we characterized dominant-negative inhibitors of the ϵ-toxin. Site-specific mutations were introduced into the gene encoding ϵ-toxin, and recombinant proteins were expressed in Escherichia coli. Paired cysteine substitutions were introduced at locations predicted to form a disulfide bond. One cysteine in each mutant was introduced into the membrane insertion domain of the toxin; the second cysteine was introduced into the protein backbone. Mutant proteins with cysteine substitutions at amino acid positions I51/A114 and at V56/F118 lacked detectable cytotoxic activity in a MDCK cell assay. Cytotoxic activity could be reconstituted in both mutant proteins by incubation with dithiothreitol, indicating that the lack of cytotoxic activity was attributable to the formation of a disulfide bond. Fluorescent labeling of the cysteines also indicated that the introduced cysteines participated in a disulfide bond. When equimolar mixtures of wild-type ϵ-toxin and mutant proteins were added to MDCK cells, the I51C/A114C and V56C/F118C mutant proteins each inhibited the activity of wild-type ϵ-toxin. Further analysis of the inhibitory activity of the I51C/A114C and V56C/F118C mutant proteins indicated that these proteins inhibit the ability of the active toxin to form stable oligomeric complexes in the context of MDCK cells. These results provide further insight into the properties of dominant-negative inhibitors of oligomeric pore-forming toxins and provide the basis for developing new therapeutics for treating intoxication by ϵ-toxin.
Discussing Disgust: The Role of Disgust with Life in Suicide

Although predominantly studied within the context of taste aversion, the definition of disgusting stimuli has been continually broadened and refined. Recent evidence has indicated that disgust may play a crucial role in the development and maintenance of various psychopathologies (McNally, 2002). Yet, research examining the role of disgust in suicidal ideation and behavior has been limited. In this paper, we highlight the potential role of disgust with life in the development and maintenance of severe suicidal ideation and behavior and suggest future directions for study.
The Representativeness Heuristic and the Conjunction Fallacy Effect in Children's Decision Making.

The use of the representativeness heuristic by second, fourth, and sixth graders showed a developmental increase in (a) base rate information and (b) information consistent with stereotypes about the story characters. Children used and extended information about the elderly to base their judgments on their construal of individuating information. Conjunction problems, concerning how likely elderly or young adults would engage in certain occupations or activities, showed children susceptible to the conjunction fallacy. Findings on both problems indicate the use of decision heuristics in the early grade-school years, and thus should be the years for beginning programs to lessen errors in social-decision judgments.
Typologies of male batterers: three subtypes and the differences among them.

Previous typologies of male batterers, including typologies developed by means of rational-deductive and empirical-inductive strategies, are reviewed. On the basis of this review, 3 descriptive dimensions (i.e., severity of marital violence, generality of the violence [toward the wife or toward others], and psychopathology/personality disorders) that consistently have been found to distinguish among subtypes of batterers are identified. These dimensions are used to propose a typology consisting of 3 subtypes of batterers (i.e., family only, dysphoric/borderline, and generally violent/antisocial). A developmental model of marital violence is then presented, and the previous literature is reviewed to examine how each batterer subtype might differ on variables of theoretical interest. Finally, some of the methodological limitations of previous typology research are reviewed, and suggestions for future work are offered.
Hongcun, China—Residents' Perceptions of the Impacts of Tourism on a Rural Community: A Mixed Methods Approach

The article reports the results of a mixed methods research study with a sample of 418 respondents in a quantitative study and semistructured interviews with 40 respondents, both sets of respondents residing in the village of Hongcun, Anhui Province, China. The quantitative study involved approximately 43% of the adult village residents. Hongcun is a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage site that hosts over 500,000 visitors a year, of whom the majority are domestic Chinese. The research was informed not only by past literature relating to the community impacts of tourism but also issues pertaining to place attachment, research paradigms, and the relevancy of past non-Chinese research to the Chinese context. There was evidence that the village still embraces tourism although disquiet existed as to past contractual arrangements made on behalf of the village. It was also found that the quantitative and qualitative data were mutually congruent, although the latter provided insights missing from the former. It is recommended that when past research is replicated in new cultural settings there is a need for a mixed methods approach to be adopted because dependency upon quantitative methods alone may fail to provide important contextual material.
Patients with differentiated thyroid cancer who underwent radioiodine thyroid remnant ablation with low-activity ¹³¹I after either recombinant human TSH or thyroid hormone therapy withdrawal showed the same outcome after a 10-year follow-up.

BACKGROUND No long-term follow-up data are available for differentiated thyroid carcinoma (DTC) patients prepared with either exogenous or endogenous TSH and treated with low-activity (1.1 GBq [30 mCi]) radioiodine (¹³¹I). AIM The aim of this study was to evaluate the 10-year follow-up of DTC patients who underwent remnant ablation with 1.1 GBq ¹³¹I after l-T4 withdrawal, recombinant human TSH (rhTSH) administration, or both. PATIENTS A total of 159 DTC patients treated with total thyroidectomy and 1.1 GBq (30 mCi) of ¹³¹I for remnant ablation and stimulated with rhTSH and/or endogenous TSH were separated into ablated (n = 115) and not ablated (n = 44) patients and prospectively followed-up for at least 10 years. In addition, we evaluated several features that could correlate with the final status of patients. RESULTS During the follow-up, 4 of 115 (3.5%) ablated patients showed a recurrence and 1 was successfully cured. Among not ablated patients, 16 of 44 (36.4%) had a persistent disease. At the end of the 10-year follow-up, 140 of 159 (88.1%) patients were disease-free, whereas 19 of 159 (11.9%) remained affected. No correlation was found with the type of TSH stimulation, and no other clinical and pathological features showed any correlation with the final status. However, low levels of stimulated serum thyroglobulin (<5.4 ng/mL) at first control after remnant ablation identified a subgroup of not ablated patients who became spontaneously cured. CONCLUSIONS Long-term outcomes are similar in DTC patients treated with 1.1 GBq (30 mCi) ¹³¹I and prepared either with rhTSH or endogenous TSH. It is of interest that serum thyroglobulin at first control after ablation can have a prognostic role.
Assessing Intervention Responsiveness: Conceptual and Technical Issues

Implementing an intervention responsiveness approach to the identification of learning disabilities (LD) requires specification of procedures for the assessment process. In this article, the author uses examples in the literature to explore conceptual and technical issues associated with options for specifying three assessment components: the timing of the measurement of student response to intervention; the criterion for demarcating learning as inadequate (below which students are identified as LD); and the nature of the intervention. Then, the author summarizes research contrasting alternative assessment methods within an intervention responsiveness approach to LD identification. Conclusions are drawn, and future related work is described.
Seizure-Induced Alterations in Cerebrovascular Function in the Neonate

Epileptiform seizures are most common during the neonatal period, affecting at least 0.3% of term neonates and more than 10% of preterm neonates. The adverse impact of neonatal seizures on the long-term neurological outcome has been well documented, but their cerebrovascular consequences are rarely emphasized. The cerebral blood flow is controlled by the interaction of the vascular and parenchymal cells forming the neurovascular unit via multiple mediator systems that have unique features in the newborn. Seizures drastically affect the neurovascular unit, resulting in (1) dramatic increases in brain metabolism and cerebral blood flow during the ictal period, (2) disruption of the blood-brain barrier, (3) an acute loss of cerebral pressure autoregulation, and (4) a delayed impairment of cerebrovascular reactivity to various stimuli. Furthermore, seizures frequently accompany and potentially aggravate a pre-existing cerebrovascular insult. This review summarizes the current knowledge on how seizures affecting various cells in the neurovascular unit result in the observed alterations in cerebrovascular function in the neonate.
Gay, lesbian and bisexual titles: their treatment in the review media and their selection by libraries

Reports on a comparison of the 1992 Lambda Book Award titles and a sample of titles reviewed in the Lambda Book Report with a control group of titles listed in Publishers Weekly, “Forecasts”. Finds that while the Lambda Award titles received about the same number of reviews as the control group titles, the LBR sample received significantly fewer reviews. However, both samples of gay/lesbian/ bisexual books are held in significantly fewer OCLC libraries than are the control titles. Examines the content of reviews of sample books and finds that they show no apparent bias on the part of the reviewers.
A Note on Life-Cycle Funds

Life-cycle or target-date funds have been gaining tremendous market share and were recently set as default choice of asset allocation in numerous defined contribution schemes or related old age provision products in many countries. Hence, an appropriate assessment of life-cycle funds’ risk-return profiles – i.e. the probability distribution of returns – is essential for sustainable financial planning concerning a large group of investors. The core idea of lifecycle funds is to decrease the fund’s equity exposure and conversely increase its bond exposure towards the fund’s target date. This paper studies the risk-return profile of life-cycle funds in particular compared to standard balanced or lifestyle funds that apply a constant equity portion throughout the fund’s term instead. Assuming a Black-Scholes model, we derive balanced funds that reproduce the risk-return profile of an arbitrary life-cycle fund considering single and regular contributions. We then investigate our results’ accuracy applying more sophisticated asset models including stochastic interest rates, stochastic equity volatility and jumps. We further compare our methodology to approximations used so far only taking into account the life-cycle funds’ average equity portion throughout the funds’ term and conclude that this approximation fails in approximating the life-cycle funds’ risk-return profile properly. Our results on the one side facilitate sustainable financial planning and on the other side challenge the very existence of life-cycle funds since appropriately calibrated balanced funds can offer a similar risk-return profile.

THE SIZE, DENSITY, AND FORMATION OF THE ORCUS–VANTH SYSTEM IN THE KUIPER BELT

The Kuiper Belt object (KBO) Orcus and its satellite Vanth form an unusual system in the Kuiper Belt. While most large KBOs have small satellites in circular orbits and smaller KBOs and their satellites tend to be much closer in size, Orcus sits in between these two regimes. Orcus is among the largest objects known in the Kuiper Belt, but the relative size of Vanth is much larger than that of the tiny satellites of the other large objects. Here, we characterize the physical and orbital characteristics of the Orcus–Vanth system in an attempt to distinguish discuss possible formation scenarios. From Hubble Space Telescope observations, we find that Orcus and Vanth have different visible colors and that Vanth does not share the water ice absorption feature seen in the infrared spectrum of Orcus. We also find that Vanth has a nearly face-on circular orbit with a period of 9.5393 ± 0.0001 days and semimajor axis of 8980 ± 20 km, implying a system mass of (6.32 ± 0.01) × 1020 kg or 3.8% the mass of dwarf planet Eris. From Spitzer Space Telescope observations, we find that the thermal emission is consistent with a single body with diameter 940 ± 70 km and a geometric albedo of 0.28 ± 0.04. Assuming equal densities and albedos, this measurement implies sizes of Orcus and Vanth of 900 and 280 km, respectively, and a mass ratio of 33. Assuming a factor of 2 lower albedo for the non-icy Vanth, however, implies sizes of 860 km and 380 km and a mass ratio of 12. The measured density depends on the assumed albedo ratio of the two objects but is approximately 1.5 ± 0.3 g cm−3, midway between typical densities measured for larger and smaller objects. The orbit and mass ratio is consistent with formation from a giant impact and subsequent outward tidal evolution, and even consistent with the system having now achieved a double synchronous state. Because of the large angle between the plane of the heliocentric orbit of Orcus and the plane of the orbit of Vanth, the system can be equally well explained, however, by initial eccentric capture, Kozai cycling to increase the eccentricity and decrease the pericenter of the orbit of Vanth, and subsequent inward tidal evolution. We discuss implications of these formation mechanisms.
Secretory IgA response against Pseudomonas aeruginosa in the upper airways and the link with chronic lung infection in cystic fibrosis

We assessed the diagnostic ability of an enzyme-linked immunosorbent assay test for measurement of specific secretory IgA (sIgA) in saliva to identify cystic fibrosis (CF) patients with Pseudomonas aeruginosa chronic lung infection and intermittent lung colonization. A total of 102 Brazilian CF patients and 53 healthy controls were included. Specific serum IgG response was used as a surrogate to distinguish CF patients according to their P. aeruginosa colonization/infection status. The rate of sIgA positivity was 87.1% in CF chronically infected patients (median value = 181.5 U/mL), 48.7% in intermittently colonized patients (median value = 45.8 U/mL) and 21.8% in free of infection patients (median value = 22.1 U/mL). sIgA levels in saliva were significantly associated with serum P. aeruginosa IgG and microbiological culture results. The sensitivity, specificity, PPV and NPV for differentiation between presence and absence of chronic lung infection were 87%, 63%, 51% and 92%, respectively. Measurement of sIgA in saliva may be used for screening patients in risk of developing P. aeruginosa chronic lung infection in CF and possibly also for paranasal sinusitis, and, most importantly, to efficiently rule out chronic P. aeruginosa lung infection.
