Dietary intake and nutritional risk in Mediterranean adolescents in relation to the severity of the eating disorder

Abstract Objective To assess the relationship between the degree of severity of eating disorders (ED) and energy and nutrient intakes and nutritional risk in a mixed-sex adolescent population without clinical symptoms. Design Cross-sectional study. Setting Data were collected in schools. Subjects Adolescents (n 495) aged 14·2 (sd 1·0) years. The Eating Attitudes Test was used to detect adolescents at risk of ED (rED) and a structured interview based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, was used to diagnose eating disorder not otherwise specified (EDNOS). Dietary intake was quantified using the 24 h recall method over three days and the probability of inadequate intake was determined. Results Females presented lower intakes of energy, macronutrients and micronutrients (Ca, Fe, Mg, K, P, Na, thiamin, vitamins E, C, B6, B12, pantothenic acid, folic acid) because the severity of their ED was greater. These lower dietary intakes led to nutritional risk (for Ca, Fe, Mg, P, vitamins A, D, B6) in more than 80 % and 60 % of females with EDNOS and rED, respectively. The multiple linear regression models showed that the rED and EDNOS groups presented a lower energy intake of 1597·4 kJ/d (381·8 kcal/d) and 3153·0 kJ/d (753·6 kcal/d), respectively. In contrast, little difference was observed in the nutritional intakes of males. Conclusions The female adolescents showed lower energy and nutrient intakes as the ED became more severe, which led to energy, vitamin and mineral deficiencies in a high percentage of females with ED. These nutritional risks could hinder adequate physical and psychological development and lead to chronic ED.
A Modified Bacillus Calmette-Guérin (BCG) Vaccine with Reduced Activity of Antioxidants and Glutamine Synthetase Exhibits Enhanced Protection of Mice despite Diminished in Vivo Persistence

Early attempts to improve BCG have focused on increasing the expression of prominent antigens and adding recombinant toxins or cytokines to influence antigen presentation. One such modified BCG vaccine candidate has been withdrawn from human clinical trials due to adverse effects. BCG was derived from virulent Mycobacterium bovis and retains much of its capacity for suppressing host immune responses. Accordingly, we have used a different strategy for improving BCG based on reducing its immune suppressive capacity. We made four modifications to BCG Tice to produce 4dBCG and compared it to the parent vaccine in C57Bl/6 mice. The modifications included elimination of the oxidative stress sigma factor SigH, elimination of the SecA2 secretion channel, and reductions in the activity of iron co-factored superoxide dismutase and glutamine synthetase. After IV inoculation of 4dBCG, 95% of vaccine bacilli were eradicated from the spleens of mice within 60 days whereas the titer of BCG Tice was not significantly reduced. Subcutaneous vaccination with 4dBCG produced greater protection than vaccination with BCG against dissemination of an aerosolized challenge of M. tuberculosis to the spleen at 8 weeks post-challenge. At this time, 4dBCG-vaccinated mice also exhibited altered lung histopathology compared to BCG-vaccinated mice and control mice with less well-developed lymphohistiocytic nodules in the lung parenchyma. At 26 weeks post-challenge, 4dBCG-vaccinated mice but not BCG-vaccinated mice had significantly fewer challenge bacilli in the lungs than control mice. In conclusion, despite reduced persistence in mice a modified BCG vaccine with diminished antioxidants and glutamine synthetase is superior to the parent vaccine in conferring protection against M. tuberculosis. The targeting of multiple immune suppressive factors produced by BCG is a promising strategy for simultaneously improving vaccine safety and effectiveness.
Unusually large number of methicillin-resistant Staphylococcus aureus clones in a Portuguese hospital

Methicillin-resistant Staphylococcus aureus (MRSA) has been endemic in Hospital de Santa Maria, a 1,300-bed teaching hospital in Lisbon, Portugal, since the mid-1980s with a prevalence of 30% in 1993. A total of 54 MRSA and 93 methicillin-susceptible S. aureus (MSSA) isolates recovered during the first 3 months of 1993 were analyzed for the particular mecA polymorphs and Tn554 attachment sites (in the case of MRSA) and for pulsed-field gel electrophoretic patterns. While all MRSA isolates shared a very similar multidrug resistance antibiogram, molecular methods allowed the identification of an unusually large number of genetic backgrounds (24 different pulsed-field gel electrophoresis patterns in 54 isolates) and three different mecA polymorphs among the MRSA strains. Similar large variation in the genetic backgrounds of MSSA was observed. The most frequent mecA polymorph (mecA type I) was found in association with three different Tn554 patterns. Among the MRSA strains of Hospital Santa Maria, we found two clonal types previously described in Portugal: one corresponding to the dominant clone in an MRSA outbreak at the pediatric ward of the Lisbon Hospital Dona Estefânia and another one identical to the Iberian epidemic clone identified in several Portuguese hospitals and in MRSA outbreaks in Barcelona and Madrid. This suggests that MRSA clones of Hospital de Santa Maria may have been a reservoir for staphylococcal strains over the past decade.
Convexity and singularities of curvature equations in conformal geometry

We define a generalization of convex functions, which we call $\delta$-convex functions, and show they must satisfy interior H\"older and $W^{1,p}$ estimates. As an application, we consider solutions of a certain class of fully nonlinear equations in conformal geometry with isolated singularities, in the case of non-negative Ricci curvature. We prove that such solutions either extend to a H\"older continuous function across the singularity, or else have the same singular behavior as the fundamental solution of the conformal Laplacian. We also obtain various removable singularity theorems for these equations.
Arterial tortuosity syndrome: clinical and molecular findings in 12 newly identified families

Arterial tortuosity syndrome (ATS) is a rare autosomal recessive connective tissue disease, characterized by widespread arterial involvement with elongation, tortuosity, and aneurysms of the large and middle‐sized arteries. Recently, SLC2A10 mutations were identified in this condition. This gene encodes the glucose transporter GLUT10 and was previously suggested as a candidate gene for diabetes mellitus type 2. A total of 12 newly identified ATS families with 16 affected individuals were clinically and molecularly characterized. In addition, extensive cardiovascular imaging and glucose tolerance tests were performed in both patients and heterozygous carriers. All 16 patients harbor biallelic SLC2A10 mutations of which nine are novel (six missense, three truncating mutations, including a large deletion). Haplotype analysis suggests founder effects for all five recurrent mutations. Remarkably, patients were significantly older than those previously reported in the literature (P=0.04). Only one affected relative died, most likely of an unrelated cause. Although the natural history of ATS in this series was less severe than previously reported, it does indicate a risk for ischemic events. Two patients initially presented with stroke, respectively at age 8 months and 23 years. Tortuosity of the aorta or large arteries was invariably present. Two adult probands (aged 23 and 35 years) had aortic root dilation, seven patients had localized arterial stenoses, and five had long stenotic stretches of the aorta. Heterozygous carriers did not show any vascular anomalies. Glucose metabolism was normal in six patients and eight heterozygous individuals of five families. As such, overt diabetes is not related to SLC2A10 mutations associated with ATS. Hum Mutat 29(1), 150–158, 2008. © 2007 Wiley‐Liss, Inc.
The Berlin Brain–Computer Interface: Non-Medical Uses of BCI Technology

Brain–computer interfacing (BCI) is a steadily growing area of research. While initially BCI research was focused on applications for paralyzed patients, increasingly more alternative applications in healthy human subjects are proposed and investigated. In particular, monitoring of mental states and decoding of covert user states have seen a strong rise of interest. Here, we present some examples of such novel applications which provide evidence for the promising potential of BCI technology for non-medical uses. Furthermore, we discuss distinct methodological improvements required to bring non-medical applications of BCI technology to a diversity of layperson target groups, e.g., ease of use, minimal training, general usability, short control latencies.
Acute Effects of Various Weighted Bat Warm-Up Protocols on Bat Velocity

Reyes, GF and Dolny, D. Acute effects of various weighted bat warm-up protocols on bat velocity. J Strength Cond Res 23(7): 2114-2118, 2009-Although research has provided evidence of increased muscular performance following a facilitation set of resistance exercise, this has not been established for use prior to measuring baseball bat velocity. The purpose of this study was to determine the effectiveness of selected weighted bat warm-up protocols to enhance bat velocity in collegiate baseball players. Nineteen collegiate baseball players (age = 20.15 ± 1.46 years) were tested for upper-body strength by a 3-repetition maximum (RM) bench press (mean = 97.98 ± 14.54 kg) and mean bat velocity. Nine weighted bat warm-up protocols, utilizing 3 weighted bats (light = 794 g; standard = 850 g; heavy = 1,531 g) were swung in 3 sets of 6 repetitions in different orders. A control trial involved the warm-up protocol utilizing only the standard bat. Pearson product correlation revealed a significant relationship between 3RM strength and pretest bat velocity (r = 0.51, p = 0.01). Repeated measures analysis of variance (ANOVA) revealed no significant treatment effects of warm-up protocol on bat velocity. However, the order of standard, light, heavy bat sequence resulted in the greatest increase in bat velocity (+6.03%). These results suggest that upper-body muscle strength influences bat velocity. It appears that the standard, light, heavy warm-up order may provide the greatest benefit to increase subsequent bat velocity and may warrant use in game situations.
Comparison of neutrophil volume distribution width to C-reactive protein and procalcitonin as a proposed new marker of acute infection

Abstract Background: The aim of this study was to assess the use of neutrophil distribution width (NDW) and to compare it to C-reactive protein (CRP) and procalcitonin (PCT), in the detection of early sepsis in the intensive care unit. Methods: Subjects (N = 166) were divided into 4 groups: healthy, acute inflammatory non-infectious (AINI), localized infection, and systemic infection, according to clinical history and cultures. NDW, CRP, and PCT were compared among the different groups using multivariate analysis of variance (MANOVA). Diagnostic efficacy was assessed using receiver operating characteristic curves and areas under the curves (AUC). Results: The lowest meanNDW was found in the healthy group (n = 41), followed by the AINI (n = 20), localized infection (n = 55), and systemic infection (n = 50) groups. AUCNDW was 0.877 for infected (localized + systemic) vs non-infected (healthy + AINI) groups, and 0.965 for systemic infection vs non-infected groups. A cut-off of 21.9 resulted in 90% sensitivity, 92% specificity, 90% positive predictive value, and 92% negative predictive value (AUCNDW = 0.965, 95% confidence interval 0.935–0.995). According to MANOVA, only NDW was able to differentiate an acute inflammatory process from early infection in postoperative patients, but not healthy from AINI subjects. Conclusions: NDW had the highest diagnostic accuracy and is available with the complete blood count with differential (CBC). It may be a promising parameter to aid in the diagnosis of acute infection in adults, provided the possibility of haematological disorders is first ruled out.
Pseudomonas aeruginosa PqsA Is an Anthranilate-Coenzyme A Ligase

ABSTRACT Pseudomonas aeruginosa is an opportunistic human pathogen which relies on several intercellular signaling systems for optimum population density-dependent regulation of virulence genes. The Pseudomonas quinolone signal (PQS) is a 3-hydroxy-4-quinolone with a 2-alkyl substitution which is synthesized by the condensation of anthranilic acid with a 3-keto-fatty acid. The pqsABCDE operon has been identified as being necessary for PQS production, and the pqsA gene encodes a predicted protein with homology to acyl coenzyme A (acyl-CoA) ligases. In order to elucidate the first step of the 4-quinolone synthesis pathway in P. aeruginosa, we have characterized the function of the pqsA gene product. Extracts prepared from Escherichia coli expressing PqsA were shown to catalyze the formation of anthraniloyl-CoA from anthranilate, ATP, and CoA. The PqsA protein was purified as a recombinant His-tagged polypeptide, and this protein was shown to have anthranilate-CoA ligase activity. The enzyme was active on a variety of aromatic substrates, including benzoate and chloro and fluoro derivatives of anthranilate. Inhibition of PQS formation in vivo was observed for the chloro- and fluoroanthranilate derivatives, as well as for several analogs which were not PqsA enzymatic substrates. These results indicate that the PqsA protein is responsible for priming anthranilate for entry into the PQS biosynthetic pathway and that this enzyme may serve as a useful in vitro indicator for potential agents to disrupt quinolone signaling in P. aeruginosa.
Identification of the ionizing source of NGC 2024

Received; accepted Abstract. We propose the late-O, early-B star IRS2b as the ionizing source of the Flame Nebula (NGC 2024). It has been clear that such a hot, massive star must be present in this heavily obscured region, and now it has been identified. New near-infrared photometry shows that IRS2b is the most luminous and hottest star in the young star cluster embedded in the center of NGC 2024. The near-infrared observations (5 ' × 5 ' ) cover �90 % of the H ii region detected in radio continuum radiation, making the probability very low that the ionizing star is not present in the field. A K-band spectrum of IRS2b obtained with ISAAC on the Very Large Telescope indicates that the spectral type of IRS2b is in the range O8 V - B2 V. Additional arguments indicate that its spectral type is likely closer to O8 than to B2. The corresponding amount of ionizing radiation is consistent with published radio continuum and recombination line observations.
Performance of the Roche AMPLICOR human papillomavirus (HPV) test in prediction of cervical intraepithelial neoplasia (CIN) in women with abnormal PAP smear.

OBJECTIVES To assess the performance of a novel PCR-based assay (Roche AMPLICOR HPV test) in detection of cervical pathology as a part of management for abnormal PAP smear (MAPS) and in women participating in cervical cancer screening. STUDY DESIGN Altogether, 504 women comprising 270 patients referred for colposcopy due to an abnormal Pap smear and another 234 women participating in cervical cancer screening (tested for comparison) were analyzed for oncogenic (HR) Human papillomavirus (HPV) types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68 using the Roche AMPLICOR HPV test in cervical samples collected in PreservCyt liquid media. Colposcopic biopsy and/or LEEP cone biopsy was used as the gold standard in the triage group, while liquid-based cytology (LBC) was the reference test in the screening group. RESULTS The prevalence of HPV was significantly higher in the MAPS group (65.9%) than in the screening group (31.2%) (P = 0.0001). There was a poor concordance between the referral PAP and the current LBC, being only moderate in the screening series, ICC (weighted kappa) = 0.291 (95%CI 0.070-0.459) (P = 0.007), and almost poor in the MAPS Series, with ICC = 0.217 (95%CI 0.04-0.384) (P = 0.023). AMPLICOR HPV positivity increased linearly with the increasing grade of cervical lesions. In detecting high-grade (CIN2-3), colposcopy was the most sensitive test (96.5%), very similar to AMPLICOR (95.2%) (P = 0.731), while LBC with HSIL cutoff was by far the most specific test (99.5%) and showed the highest PPV (96.1%). NPV of colposcopy (97.2%) and AMPLICOR (96.7%) were similar (P = 0.839). Together with abnormal colposcopy and HSIL cytology, the AMPLICOR HPV test is a powerful independent predictor of high-grade CIN2-3, and as such suitable to replace cervical cytology in management of women with abnormal PAP test (MAPS). CONCLUSIONS The Roche AMPLICOR HPV test is comparable to other HPV tests (HCII, PCR) in detecting CIN in MAPS. However, more data are clearly needed on the performance of AMPLICOR test in management of abnormal PAP and particularly as a screening tool.
Passion and Intrinsic Motivation in Digital Gaming

Digital gaming is fast becoming a favorite activity all over the world. Yet very few studies have examined the underlying motivational processes involved in digital gaming. One motivational force that receives little attention in psychology is passion, which could help us understand the motivation of gamers. The purpose of the present study was to identify subgroups of young people with distinctive passion profiles on self-determined regulations, flow dispositions, affect, and engagement time in gaming. One hundred fifty-five students from two secondary schools in Singapore participated in the survey. There were 134 males and 8 females (13 unspecified). The participants completed a questionnaire to measure harmonious passion (HP), obsessive passion (OP), perceived locus of causality, disposition flow, positive and negative affects, and engagement time in gaming. Cluster analysis found three clusters with distinct passion profiles. The first cluster had an average HP/OP profile, the second cluster had a low HP/OP profile, and the third cluster had a high HP/OP profile. The three clusters displayed different levels of cognitive, affective, and behavioral outcomes. Cluster analysis, as this study shows, is useful in identifying groups of gamers with different passion profiles. It has helped us gain a deeper understanding of motivation in digital gaming.
Vancomycin and High Level Aminoglycoside Resistance in Enterococcus spp. in a Tertiary Health Care Centre: A Therapeutic Concern

Aims. This study was aimed at knowing the prevalence of vancomycin and high level aminoglycoside resistance in enterococcal strains among clinical samples. Study Design. It was an investigational study. Place and Duration of Study. It was conducted on 100 Enterococcus isolates, in the Department of Microbiology, Pt. BDS PGIMS, Rohtak, over a period of six months from July to December 2014. Methodology. Clinical specimens including urine, pus, blood, semen, vaginal swab, and throat swab were processed and Enterococcus isolates were identified by standard protocols. Antibiotic sensitivity testing of enterococci was performed using Kirby-Bauer disc diffusion method. Results. High level gentamicin resistance (HLGR) was more common in urine samples (41.5%) followed by blood (36%) samples. High level streptomycin resistance (HLSR) was more common in pus samples (52.6%) followed by blood samples (36%). Resistance to vancomycin was maximum in blood isolates. Conclusion. Enterococci resistant to multiple antimicrobial agents have been recognized. Thus, it is crucial for laboratories to provide accurate antimicrobial resistance patterns for enterococci so that effective therapy and infection control measures can be initiated.
Discrete symmetries of the superpotential and calculation of disk invariants

The integrality of Ooguri-Vafa disk invariants is verified using discrete symmetries of the superpotential of the mirror Landau-Ginzburg theory to calculate quantum corrections to the boundary variables. We show that these quantum corrections are completely determined if we assume that the discrete symmetry of the superpotential also holds in terms of the quantum corrected variables. We discuss the case of local P^2 blown up at three points and local F_2 blown up at two points in detail.
Detection of phasic dopamine by D1 and D2 striatal medium spiny neurons

Brief dopamine events are critical actors of reward‐mediated learning in the striatum; the intracellular cAMP–protein kinase A (PKA) response of striatal medium spiny neurons to such events was studied dynamically using a combination of biosensor imaging in mouse brain slices and in silico simulations. Both D1 and D2 medium spiny neurons can sense brief dopamine transients in the sub‐micromolar range. While dopamine transients profoundly change cAMP levels in both types of medium spiny neurons, the PKA‐dependent phosphorylation level remains unaffected in D2 neurons. At the level of PKA‐dependent phosphorylation, D2 unresponsiveness depends on protein phosphatase‐1 (PP1) inhibition by DARPP‐32. Simulations suggest that D2 medium spiny neurons could detect transient dips in dopamine level.
Empowering and legitimizing the fundamental attribution error: Power and legitimization exacerbate the translation of role‐constrained behaviors into ability differences

Our daily interactions are influenced by the social roles we endorse. People however underestimate these role constraints in their everyday explanation relying on individual dispositions to make sense of behaviors. Two studies investigated whether this bias is exacerbated when role structure is legitimated and when power matches the advantages conferred by the social roles of a quiz game. Legitimacy as well as power increased the tendency for both advantaged (questioner) and disadvantaged (answerer) actors (Study 1) as well as naive observers of the quiz game (Study 2) to attribute to ability the behaviors elicited by social roles. These results extend previous findings. People are more prone to explain constrained behaviors by differences in ability when role structure is legitimated and when power asymmetry matches role structure. Legitimacy and power may then play an important role in the translation of role constraints into inferences about ability.
Patient involvement in mental health care: one size does not fit all

Background Involvement of mental health‐care patients in the decision‐making processes is considered to be an ethical requirement. Health‐care systems worldwide are increasingly emphasizing the value of participatory approaches. There is, however, no consensus on the definition of patient involvement. The literature is particularly inconsistent and lacks clarity.
Wi-Fi Gesture Recognition on Existing Devices

This paper introduces the first wireless gesture recognition system that operates using existingWi-Fi signals and devices. To achieve this, we first identify limitations of existing wireless gesture recognition approaches that limit their applicability to Wi-Fi. We then introduce algorithms that can classify gestures using information that is readily available on Wi-Fi devices. We demonstrate the feasibility of our design using a prototype implementation on off-the-shelf Wi-Fi devices. Our results show that we can achieve a classification accuracy of 91% while classifying four gestures across six participants, without the need for per-participant training. Finally, we show the feasibility of gesture recognition in non-line-ofsight situations with the participants interacting with a Wi-Fi device placed in a backpack.
