Published: August 2017

AbstractObjectiveThe great majority of research on identity and personality development has focused on individual processes of development, to the relative neglect of the cultural context of development. We employ a recently articulated framework for the examination of identity development in context, centered on the construct of master narratives, or culturally shared stories.MethodAcross four studies, we asked emerging and midlife adults (N = 512) to narrate personal experiences of deviations from these master narratives.ResultsAcross three quantitative studies, we show that (a) those who elaborated their deviation experiences were more likely to be in structurally marginalized positions in society (e.g., ethnic or sexual minorities); (b) those who elaborated an empowering alternative to the master narrative were more likely to be engaged in identity processes; and (c) master narratives maintain their rigidity by the frequency of their use. In study 4, using qualitative analyses, we illustrate the rigidity of master narratives, as well as the degree to which they take shape in social and group experiences.ConclusionsThese studies emphasize the importance of cultural context in considering personality and identity development.
What's interpersonal in interpersonal perception? The role of target's attachment in the accuracy of perception
Authors: Sadikaj Gentiana , Moskowitz D. S. , Zuroff David C. 
Published: August 2017

AbstractObjectiveWe examined the influence of attachment orientation on the accuracy of perception of negative affect in close relationships. We hypothesized that tracking accuracy of perceiving negative affect (a) would be lower among perceivers and targets with higher attachment avoidance and (b) would be lowest when both the target and perceiver were high on attachment avoidance. Tracking accuracy would be (c) higher among perceivers and targets with higher attachment anxiety and (d) highest when both the target and perceiver were high on attachment anxiety.MethodWe collected data from 92 couples who reported their negative affect and perception of their partner's negative affect in interactions with each other on 20 days.ResultsResults supported the hypotheses for attachment avoidance and tracking accuracy. Tracking accuracy of perceived negative affect was low when the target was high on attachment avoidance; accuracy was lowest when both the target and the perceiver were high on attachment avoidance.ConclusionsLower “readability” of high avoidantly attached targets' emotions may inhibit intimacy and sensitive responding, which thereby may contribute to poor relationship outcomes.

AimTo describe nutritional practices among preterm extremely low‐birthweight (ELBW) infants and their impact on growth and to compare differences in nutritional intervention and comorbidities between those with limited growth velocity (GV < 25th percentile) and those with GV > 25th percentile.MethodsA prospective cohort study was conducted to assess total protein and energy intake for week 1, days 14, 21 and 28 of life. Post‐natal growth was calculated by measuring GV using an exponential model. Univariable analysis was applied to identify the potential risk factors associated with poor GV at day 28 and at discharge from hospital.ResultsThe median GV from birth to day 28 was 9.84 g/kg/day and 11.87 g/kg/day for GV from birth to discharge. Increased protein and energy intake was associated with higher GV at discharge. Hypotension needing inotropes, necrotising enterocolitis (NEC), patent ductus arteriosus and chronic lung disease were significantly associated with reduced GV at discharge. Infants with NEC, hypotension needing inotropes and sepsis took a significantly longer time to achieve full enteral nutrition. A longer time to attain full enteral feeds was associated with slower GV at discharge. Small‐for‐gestational‐age babies increased from 22% at birth to 66.6% at discharge.ConclusionsGV at discharge was positively correlated with increasing protein and energy intake in the first 28 days and adversely affected by the presence of neonatal morbidities. There was strong evidence of extra‐uterine growth restriction, with the majority of preterm ELBW infants having lower z scores at discharge compared to at birth.

AbstractBackground & AimsNorfloxacin administration is useful in preventing bacterial infections in cirrhosis but associated to the generation of resistant species. Rifaximin is known to reach high concentrations in the intestinal lumen without generating relevant resistance in the intestinal flora. Our aim was to compare the effect of Norfloxacin and Rifaximin on intestinal flora composition, bacterial translocation and survival in cirrhotic rats.MethodsCirrhosis was induced in rats by oral administration of CCl4. Animals were divided into three groups: only CCl4 (group I, n = 10); CCl4 + Norfloxacin (group II, n = 17) and CCl4 + Rifaximin (group III, n = 14). Gut bacterial composition, bacterial translocation and cytokine levels were measured.ResultsForty‐one rats were finally included. The incidence of viable and non‐viable bacterial translocation was significantly reduced in animals receiving Norfloxacin; Rifaximin also decreased the incidence of viable and non‐viable bacterial translocation, but did not reach statistical significance. Serum TNF‐α levels were significantly lower in antibiotic groups. Norfloxacin modified intestinal microbiota, depleting significantly more pathobionts than Rifaximin.ConclusionNorfloxacin is more effective than Rifaximin in preventing bacterial translocation in rats with cirrhosis probably because of its capacity to reduce pathobionts from intestinal microbiota.
Analytical approximations of local‐Heston volatility model and error analysis
Authors: Bompis R. , Gobet E. 
Published: August 2017

AbstractThis paper studies the expansion of an option price (with bounded Lipschitz payoff) in a stochastic volatility model including a local volatility component. The stochastic volatility is a square root process, which is widely used for modeling the behavior of the variance process (Heston model). The local volatility part is of general form, requiring only appropriate growth and boundedness assumptions. We rigorously establish tight error estimates of our expansions, using Malliavin calculus. The error analysis, which requires a careful treatment because of the lack of weak differentiability of the model, is interesting on its own. Moreover, in the particular case of call–put options, we also provide expansions of the Black–Scholes implied volatility that allow to obtain very simple formulas that are fast to compute compared to the Monte Carlo approach and maintain a very competitive accuracy.
Liquidity effects of trading frequency
Authors: Gayduk Roman , Nadtochiy Sergey 
Published: August 2017

AbstractIn this paper, we present a discrete‐time modeling framework, in which the shape and dynamics of a Limit Order Book (LOB) arise endogenously from an equilibrium between multiple market participants (agents). We use the proposed modeling framework to analyze the effects of trading frequency on market liquidity in a very general setting. In particular, we demonstrate the dual effect of high trading frequency. On the one hand, the higher frequency increases market efficiency, if the agents choose to provide liquidity in equilibrium. On the other hand, it also makes markets more fragile, in the sense that the agents choose to provide liquidity in equilibrium only if they are market neutral (i.e., their beliefs satisfy certain martingale property). Even a very small deviation from market neutrality may cause the agents to stop providing liquidity, if the trading frequency is sufficiently high, which represents an endogenous liquidity crisis (also known as flash crash) in the market. This framework enables us to provide more insight into how such a liquidity crisis unfolds, connecting it to the so‐called adverse selection effect.

SummaryThe PA0336 protein from Pseudomonas aeruginosa belongs to the family of widely distributed Nudix pyrophosphohydrolases, which catalyze the hydrolysis of pyrophosphate bonds in a variety of nucleoside diphosphate derivatives. The amino acid sequence of the PA0336 protein is highly similar to that of the RppH Nudix RNA pyrophosphohydrolase from Escherichia coli, which removes pyrophosphate from 5′‐end of triphosphorylated RNA transcripts. Trans‐complementation experiments showed that the P. aeruginosa enzyme can functionally substitute for RppH in E. coli cells indicating that, similar to RppH, the Pseudomonas hydrolase mediates RNA turnover in vivo. In order to elucidate the biological significance of the PA0336 protein in Pseudomonas cells, a PA0336 mutant strain was constructed. The mutated strain considerably increased level of the virulence factor pyocyanin compared to wild type, suggesting that PA0336 could be involved in downregulation of P. aeruginosa pathogenicity. This phenotype was reversed by complementation with the wild type but not catalytically inactive PA0336, indicating that the catalytic activity was indispensable for its biological function. Pathogenesis tests in Caenorhabditis elegans showed that the PA0336 mutant of P. aeruginosa was significantly more virulent than the parental strain, confirming further that the P. aeruginosa RNA pyrophosphohydrolase PA0336 modulates bacterial pathogenesis by down‐regulating production of virulence‐associated factors. To study the role of PA0336 further, transcriptomes of the PA0336 mutant and the wild‐type strain were compared using RNA sequencing. The level of 537 transcripts coding for proteins involved in a variety of cellular processes such as replication, transcription, translation, central metabolism and pathogenesis, was affected by the lack of PA0336. These results indicate that the PA0336 RNA pyrophosphohydrolase functions as a global regulator that influences many of transcripts including those involved in P. aeruginosa virulence.

AbstractThe cattle tick, Rhipicephalus microplus (Canestrini, 1888) (Ixodida: Ixodidae), is the most important ectoparasite in cattle‐breeding areas and is responsible for severe economic losses. Synthetic acaricides have been used to control this parasite. However, the need for safer products has stimulated the search for new acaricides, such as those to be obtained from medicinal plants. The essential oil of Syzygium aromaticum (clove) has many biological properties and shows great potential for use in veterinary applications. In the context of the need for new agents, this study investigated the in vitro properties of the hydrolate, essential oil and the main constituent of S. aromaticum, eugenol, in formulated and free applications against larvae and females of R. microplus. Eugenol and the essential oil caused 100% mortality in larvae at starting applications of 2.5 mg/mL and 5.0 mg/mL, respectively. The hydrolate showed no activity. Both eugenol and essential oil had good efficacy in adult immersion tests at 50 mg/mL and achieved 100% efficacy at a concentration of 100 mg/mL. The results of these tests reaffirm the important potential of clove essential oil and eugenol.

SummaryPlasma 1,3‐β‐D‐glucan (BDG) is indicated as a tool for early diagnosis of invasive fungal diseases (IFD). However, data on its diagnostic value are scarce in children. Therefore, definition of BDG test performance in paediatrics is needed. BDG was evaluated in children admitted to “Istituto Giannina Gaslini,” Genoa, Italy, who developed clinical conditions at risk for IFD. Results were analysed for sensitivity, specificity, predictive values, likelihood ratios, accuracy, informedness and probability of missing one case by a negative test. A total of 1577 BDG determinations were performed on 255 patients (49% males, median age 5.4 years). Overall 46 IFD were diagnosed, 72% proven/probable. The test performance was evaluated for 80 pg/mL, 120 pg/mL, 200 pg/mL, 350 pg/mL, 400 pg/mL cut offs. Sensitivity was always <0.80 and specificity > 0.90 only for cut offs ≥200 pg/mL. Negative predictive value was ≥0.90 for all the cut offs evaluated, while positive predictive value resulted barely 0.50 (8% IFD prevalence). Accuracy was never >0.90, and informedness was at best 0.50. The risk of missing one IFD by a negative result was < 10%. Analyses in haemato‐oncological or newborn patients did not show major differences. Detection of serum BDG does not appear a valuable adjunctive diagnostic tool for IFD in paediatrics.

ObjectiveTo evaluate the association between periodontitis and severe asthma, with participants in treatment for severe asthma, controlled by therapy.MethodsA case–control investigation was performed to compare 130 adults with severe asthma with 130 without asthma. Individuals with periodontitis were those with ≥4 teeth with ≥1 site with probing depth ≥4 mm, clinical attachment level ≥3 mm, and bleeding upon probing at the same site. Severe asthma diagnosis was based on Global Initiative for Asthma criteria.ResultsAssociation between exposure to periodontitis and severe asthma was found:ORcrude = 2.98 (95%CI: 1.74–5.11). When confounders were considered, the association between exposure to periodontitis and severe asthma was maintained:ORadjusted = 3.01–3.25. Individuals with periodontitis had about a threefold increased risk of severe asthma than those without periodontitis. Frequency of periodontitis in participants with severe asthma was greater than that of those without asthma (46.6%vs22.3%,p ≤ .05).ConclusionsAssociation between periodontitis and severe asthma was observed. Further investigation is required to determine the direction of this relationship. It may be causal, but it may also be a consequence of the immunopathological process that characterizes asthma, or else, consequence of the medication used for treatment.

AbstractBackgroundAdhesive strapping for umbilical hernia has been re‐evaluated as a promising treatment. We evaluated the influence of adhesive strapping on the outcome of umbilical hernia.MethodsWe retrospectively evaluated patients with umbilical hernia referred to the present institution from April 2011 to December 2015. Patients who were treated with adhesive strapping were compared with an observation alone group. The adhesive strapping group was also subdivided into two groups: the cure group and the treatment failure group.ResultsA total of 212 patients with umbilical hernia were referred to the present institution. Eighty‐nine patients were treated with adhesive strapping, while 27 had observation only. The cure rate in the adhesive strapping group was significantly higher than that in the observation group. The duration of treatment of the adhesive strapping group was significantly shorter than that of the observation group. In the adhesive strapping group, the patients in the cure group were treated significantly earlier than those in the treatment failure group (P < 0.001). Furthermore, even in cases of umbilical hernia non‐closure, surgical repair was easier after adhesive strapping.ConclusionAdhesive strapping represents a promising treatment for umbilical hernia. To achieve the best results, adhesive strapping should be initiated as early as possible.
Temporal dissociation of salience and prediction error responses to appetitive and aversive taste

Published: August 2017

AbstractThe feedback‐related negativity (FRN), a frontocentral ERP occurring 200–350 ms after emotionally valued outcomes, has been posited as the neural correlate of reward prediction error, a key component of associative learning. Recent evidence challenged this interpretation and has led to the suggestion that this ERP expresses salience instead. Here, we distinguish between utility prediction error and salience by delivering or withholding hedonistically matched appetitive and aversive tastes, and measure ERPs to cues signaling each taste. We observed a typical FRN (computed as the loss‐minus‐gain difference wave) to appetitive taste, but a reverse FRN to aversive taste. When tested axiomatically, frontocentral ERPs showed a salience response across tastes, with a particularly early response to outcome delivery, supporting recent propositions of a fast, unsigned, and unspecific response to salient stimuli. ERPs also expressed aversive prediction error peaking at 285 ms, which conformed to the logic of an axiomatic model of prediction error. With stimuli that most resemble those used in animal models, we did not detect any frontocentral ERP signal for utility prediction error, in contrast with dominant views of the functional role of the FRN ERP. We link the animal and human literature and present a challenge for current perspectives on associative learning research using ERPs.

ContentsOxidative stress is a major factor explaining sperm dysfunction of spermatozoa surviving freezing and thawing and is also considered a major inducer of a special form of apoptosis, visible after thawing, in cryopreserved spermatozoa. To obtain further insights into the link between oxidative stress and the induction of apoptotic changes, stallion spermatozoa were induced to oxidative stress through redox cycling after exposure to 2‐methyl‐1,4‐naphthoquinone (menadione), or hydroxyl radical formation after FeSO4 exposure. Either exposure induced significant increases (p < 0.05) in two markers of lipid peroxidation: 8‐iso‐PGF2α and 4‐hydroxynonenal (4‐HNE). While both treatments induced changes indicative of spermptosis (caspase‐3 activation and decreased mitochondrial membrane potential) (p < 0.01), menadione induced sperm necrosis and a dramatic reduction in motility and thiol content in stallion spermatozoa. Thus, we provided evidence that oxidative stress underlies spermptosis, and thiol content is a key factor for stallion sperm function.

AbstractObjectiveTo assess the rate of bacterial contamination of fluid and ports in intravenous bags in a veterinary emergency room (ER) and intensive care unit (ICU).DesignExperimental model.SettingNinety intravenous fluid bags of lactated balanced‐electrolytes solution (1 L) hung in a university hospital.InterventionsBags were hung in 2 different locations in the ER (sink and bins) and one location in the ICU (sink) for 11 days. Bags were punctured 3 times daily with a sterile needle to simulate clinical use. Injection ports were swabbed and 50 mL of fluid were collected in duplicates on days 0, 2, 4, 7, and 10. Aerobic bacterial cultures were performed on the fluid and injection port. Contamination was defined as bacterial growth of a similar phenotype across 2 consecutive times. Increase in the fluid contamination rate from day 0 was tested using an exact binomial test. Port contamination rate between locations was tested using Fisher's exact test.Main ResultsCombined bacterial growth on injection ports reached a mean (95% confidence interval) of 8.1 (0.005–16.2) cfu/port on day 10. The combined port contamination was 3.3%, 11.1%, 17.8%, and 31.1% on days 0, 2, 4, and 7, respectively. Port contamination was similar between ER and ICU. However, port contamination was higher in the sink versus the bins area (38.3% vs 16.7%, P = 0.032). No fluid bag was contaminated at days 0 and 2. The contamination rate of fluid bag was 1.1% and 4.4% on days 4 and 7, respectively. All bags with contaminated fluid were in the ER (6.7%, 95% exact binomial confidence interval 1.9–16.2%).ConclusionsInjection port contamination reached 31.1% on day 7. Contamination was more likely when the bags were hung next to a sink. In our model of bag puncture, fluid contamination occurred between days 2 and 4.
Prevention of transfusion‐associated graft‐versus‐host disease with pathogen‐reduced platelets with amotosalen and ultraviolet A light: a review
Authors: Cid J. 
Published: August 2017

Background and ObjectivesTransfusion‐associated graft‐versus‐host disease (TA‐GVHD) is a serious complication of blood component transfusion therapy, caused by donor T lymphocytes. γ‐Irradiation or pathogen inactivation methods, capable of inactivating proliferating T cells in blood components, should be selected to prevent TA‐GVHD. This review summarizes the published evidence to support the use of pathogen‐reduced platelets with amotosalen (150 μm) and ultraviolet A light (UVA, 320–400 nm, 3 J/cm2) for preventing TA‐GVHD.Materials and MethodsAvailable literature on the use of pathogen‐reduced platelets to prevent TA‐GVHD was reviewed.ResultsObservational studies, animal models, in vitro studies and mechanistic studies of pathogen‐reduced platelets with amotosalen and UVA light showed that inactivation of T cells are equal or even superior to γ‐irradiation.ConclusionPathogen‐reduced platelets with amotosalen and UVA light can be used as a measure to prevent TA‐GVHD.
