Use of multiple performance and symptom validity measures: Determining the optimal per test cutoff for determination of invalidity, analysis of skew, and inter-test correlations in valid and invalid performance groups

Abstract Objective: Discrimination of patients passing vs. failing the Word Memory Test (WMT) by performance on 11 performance and symptom validity tests (PVTs, SVTs) from the Meyers Neuropsychological Battery (MNB) at per-test false positive cutoffs ranging from 0 to 15%. PVT and SVT intercorrelation in subgroups passing and failing the WMT, as well as the degree of skew of the individual PVTs and SVT in the pass/fail subgroups, were also analyzed. Method: In 255 clinical and forensic cases, 100 failed and 155 passed the WMT, at a base-rate of invalid performance of 39.2%. Performance was contrasted on 10 PVTs and 1 SVT from the MNB, using per-test false positive rates of 0.0%, 3.3%, 5.0%, 10.0%, and 15.0% in discriminating WMT pass and WMT fail groups. These two WMT groups were also contrasted using the 10 PVTs and 1 SVT as continuous variables in a logistic regression. Results: The per-PVT false positive rate of 10% yielded the highest WMT pass/fail classification, and more closely approximated the classification obtained by logistic regression than other cut scores. PVT and SVT correlations were higher in cases failing the WMT, and data were more highly skewed in those passing the WMT. Conclusions: The optimal per-PVT and SVT cutoff is at a false positive rate of 10%, with failure of ≥3 PVTs/SVTs out of 11 yielding sensitivity of 61.0% and specificity of 90.3%. PVTs with the best classification had the greatest degree of skew in the WMT pass subgroup.
Characterizing valve dynamics in mice by high‐resolution cine‐MRI

In calcific aortic valve disease (CAVD), progressive valvular sclerosis and calcification cause narrowing of the orifice and an impairment of the valve's function. We applied high‐resolution cine‐MRI to perform quantitative analysis of the dynamics of the aortic valve in a mice model of CAVD.
Static Postural Balance in Modern Pentathletes: A Pilot Study

Postural balance is a key element of shooting effectiveness, which determines the outcome of modern pentathlon competitions. The aim of the study is to examine the postural balance of 27 pentathletes (12 females and 15 males; mean age: 18.0 ± 1.8 years), and 26 physically active, untrained subjects (12 females and 14 males; mean age: 22.5 ± 1.4 years), and to investigate the impact of footwear on the stability of the shooting position in pentathletes. Methods: Static postural balance was examined during quiet stance in four test conditions (standing in footwear with eyes opened, standing in footwear with eyes closed, standing barefoot with eyes opened, and standing barefoot with eyes closed). During each postural balance measurement, the participant remained still on the platform, with their arms in front of their body. Postural balance in the shooting position was only evaluated in the group of pentathletes. The athlete was asked to assume a comfortable shooting position on the platform and to aim at the target. Standard pentathlon targets and pistols were used in the study. Measurements were carried out twice (barefoot and in footwear). Results: In all conditions, pentathletes achieved lower values of posturographic measures than in the control group. In non-visual conditions, measures describing the surface area of the centre of pressure decreased in pentathletes and increased in the control group. Both pentathletes and non-athletes were equally stable barefoot as in footwear. Footwear did not affect postural sway in the shooting position in pentathletes. Conclusions: Pentathletes were found to have significantly better stance stability and were less vision-dependent in postural balance than untrained subjects. Bearing in mind that the shooting position of pentathletes was as stable barefoot as in footwear, the main factors which were most likely responsible for minimising body oscillations in the pentathletes were their high level of concentration and conscious control of body alignment.
Role of Integrins in Resistance to Therapies Targeting Growth Factor Receptors in Cancer

Integrins contribute to cancer progression and aggressiveness by activating intracellular signal transduction pathways and transducing mechanical tension forces. Remarkably, these adhesion receptors share common signaling networks with receptor tyrosine kinases (RTKs) and support their oncogenic activity, thereby promoting cancer cell proliferation, survival and invasion. During the last decade, preclinical studies have revealed that integrins play an important role in resistance to therapies targeting RTKs and their downstream pathways. A remarkable feature of integrins is their wide-ranging interconnection with RTKs, which helps cancer cells to adapt and better survive therapeutic treatments. In this context, we should consider not only the integrins expressed in cancer cells but also those expressed in stromal cells, since these can mechanically increase the rigidity of the tumor microenvironment and confer resistance to treatment. This review presents some of these mechanisms and outlines new treatment options for improving the efficacy of therapies targeting RTK signaling.
Can Trained Dogs Detect a Hypoglycemic Scent in Patients With Type 1 Diabetes?

In persons with type 1 diabetes (T1D), hypoglycemia is common and sometimes serious. Anecdotal reports suggest that dogs can detect hypoglycemia in their human companions. The current study was undertaken to assess whether dogs can detect hypoglycemia by scent alone. The study was approved by the Human Institutional Review Board and the Animal Care and Use Committee at Legacy Research Institute (Portland, OR). Three patients with T1D were enrolled (age 25–57 years; duration of diabetes 2–21 years; none were hypoglycemic unaware). These people were unfamiliar to the dogs that were studied. For each of two hypoglycemic periods (capillary blood specimens ≤60 mg/dL), each subject collected two sterile cotton swab samples by rubbing them on the skin of both arms. Additional samples were collected during two normoglycemic episodes (capillary glucose 100–150 mg/dL). This procedure was chosen …
Predictive Value of Soluble Intercellular Adhesion Molecule-1 for Risk of Ischemic Events in Individuals with Cerebrovascular Disease

Background and Purpose: Cellular adhesion molecules may play a critical role in the inflammatory process leading to atherosclerosis. The purpose of this study was to determine whether soluble intercellular adhesion molecule-1 (sICAM-1) is a predictor of future ischemic events in high-risk individuals and also whether it is associated with carotid artery stenosis. Methods: We conducted a prospective study of sICAM-1 concentration in 3 groups: (1) subjects with recent (<7 days) ischemic stroke or TIA, (2) asymptomatic subjects with carotid stenosis ≧ 50% and (3) asymptomatic individuals with vascular risk factors. Subjects were followed for a minimum of 3 years. sICAM-1 levels were compared between the groups and correlated with the risk of ischemic events and the degree of carotid artery stenosis. Results: We studied 275 subjects. Mean sICAM-1 levels were significantly higher in those with recent ischemic stroke or TIA compared to those with risk factors alone. During follow-up, ischemic events occurred almost nine times more frequently in subjects in group 1 compared to group 3. sICAM-1 concentration was not predictive of future ischemic events (OR 1.001, 95% CI 0.998–1.004). There was no significant association between sICAM-1 concentration and carotid artery stenosis (OR 1.001, 95% CI 0.999–1.004). Conclusions: Mean sICAM-1 levels were higher in subjects with recent cerebral ischemia. No association between sICAM-1 and carotid artery stenosis was observed. Neither baseline nor subsequent sICAM-1 levels were predictive of the risk of future ischemic events.
microRNA‐96 promotes osteoblast differentiation and bone formation in ankylosing spondylitis mice through activating the Wnt signaling pathway by binding to SOST

Ankylosing spondylitis (AS) refers to a type of arthritis manifested with chronic inflammation of spine joints. microRNAs (MiRNAs) have been identified as new therapeutic targets for inflammatory diseases. In this study, we evaluated the influence of microRNA‐96 (miR‐96) on osteoblast differentiation together with bone formation in a murine model of AS. The speculated relationship that miR‐96 could bind to sclerostin (SOST) was verified by dual luciferase reporter assay. After successful model establishment, the mice with AS and osteoblasts isolated from mice with AS were treated with mimics or inhibitors of miR‐96, or DKK‐1 (a Wnt signaling inhibitor). The effects of gain‐ or loss‐of‐function of miR‐96 on the inflammatory cytokine release (IL‐6, IL‐10, and TNF‐α), alkaline phosphatase (ALP) activity, calcium nodule formation, along with the viability of osteoblasts were determined. It was observed that miR‐96 might target and regulate SOST. Besides, miR‐96 was expressed at a high level in AS mice while SOST expressed at a low level. TOP/FOP‐Flash luciferase reporter assay confirmed that miR‐96 activated the Wnt signaling pathway. Moreover, AS mice overexpressing miR‐96 exhibited increased contents of IL‐6, IL‐10 and TNF‐α, ALP activity, calcium nodule numbers, and viability of osteoblasts. In contrast, inhibition of miR‐96 resulted in suppression of the osteoblast differentiation and bone formation. In conclusion, the study implicates that overexpressing miR‐96 could improve osteoblast differentiation and bone formation in AS mice via Wnt signaling pathway activation, highlighting a potential new target for AS treatment.
Involvement of Salicylic Acid in Anthracnose Infection in Tea Plants Revealed by Transcriptome Profiling

Anthracnose is a major leaf disease in tea plant induced by Colletotrichum, which has led to substantial losses in yield and quality of tea. The molecular mechanism with regards to responses or resistance to anthracnose in tea remains unclear. A de novo transcriptome assembly dataset was generated from healthy and anthracnose-infected leaves on tea cultivars “Longjing-43” (LJ43) and “Zhenong-139” (ZN139), with 381.52 million pair-end reads, encompassing 47.78 billion bases. The unigenes were annotated versus Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), National Center for Biotechnology Information (NCBI) non-redundant protein sequences (Nr), evolutionary genealogy of genes: Non-supervised Orthologous Groups (eggNOG) and Swiss-prot. The number of differential expression genes (DEGs) detected between healthy and infected leaves was 1621 in LJ43 and 3089 in ZN139. The GO and KEGG enrichment analysis revealed that the DEGs were highly enriched in catalytic activity, oxidation-reduction, cell-wall reinforcement, plant hormone signal transduction and plant-pathogen interaction. Further studies by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) and high-performance liquid chromatography (HPLC) showed that expression of genes involved in endogenous salicylic acid biosynthesis and also accumulation of foliar salicylic acid are involved in the response of tea plant to anthracnose infection. This study firstly provided novel insight in salicylic acid acting as a key compound in the responses of tea plant to anthracnose disease. The transcriptome dataset in this study will facilitate to profile gene expression and metabolic networks associated with tea plant immunity against anthracnose.
Early Shared Reading Is Associated with Less Harsh Parenting.

OBJECTIVE Shared reading is believed to enhance parent-child relationships, but the extent to which it reduces harsh parenting is understudied. Associations between early shared reading and subsequent harsh parenting were investigated. METHODS Data from a national urban birth cohort were used to estimate associations between mother-reported shared reading at ages 1 and 3 years and harsh parenting-based on a composite of psychological and physical aggression subscales of a validated self-report instrument-when the children were at ages 3 and 5 years. The authors used multivariable linear regression and generalized estimating equations to account for repeated observations. Given potential inverse associations between shared reading and child disruptive behaviors, which can trigger harsh parenting, the authors investigated the extent to which children's behavior at age 3 years mediated the association between shared reading at age 1 year and harsh parenting at age 5 years. RESULTS This study included 2165 mother-child dyads. Thirty-four percent and 52% of mothers reported daily reading at ages 1 and 3 years. In adjusted models, shared reading at age 1 year was associated with less harsh parenting at age 3 years. Similarly, shared reading at age 3 years was associated with less harsh parenting at age 5 years. These associations remained significant in lagged repeated-measures models. Decreased disruptive behaviors partially mediated the association between shared reading at age 1 year and harsh parenting at age 5 years. CONCLUSION Shared reading predicted less harsh parenting in a national urban sample. These findings suggest that shared reading contributes to an important aspect of the parent-child relationship and that some of the association operates through enhanced child behaviors.
[The inappropriateness in the use of female cancer screening tests in Italy: over- and under-utilization determinants].

OBJECTIVES to identify the determinants of over and under-use of Pap test and mammography in the screening programme target population. DESIGN cross-sectional study. SETTING E PARTICIPANTS: we used data from the National Health interview conducted by the Italian National Institute of Statistics in 2012-2013 obtaining nation-wide representative samples of the female resident population aged 25-64 years (No. 32,831; target age of Pap test) and 50-69 years (No. 16,459; target age of mammography). MAIN OUTCOME MEASURES overall coverage: proportion of women in the target age with at least one test in lifetime; appropriate coverage: proportion of women reporting to have at least one or more tests following the first one with the recommended frequency (three and two years for Pap test and mammography, respectively); over-use: women reporting to repeat test at higher frequency; under-use: women reporting not having ever had a test or having test at longer intervals. For frequency outcomes, only women aged 28-64 years and 52-69 years were included for Pap test and mammography, respectively. RESULTS 11.9% of women have Pap test at the recommended frequency, 48.5% at shorter intervals, and 19.6% at longer intervals than recommended, while 20.0% never had a Pap test at all (39.6% under-use). 41.1% of women have a mammography at the recommended interval, 18.4% at shorter intervals, and 20.2% at longer intervals, while 20.3% never had a mammography at all. For both tests, in the North-East higher appropriate coverage and less over-use are observed, while in the South more under-use is highlighted. Young, foreigners, single, less educated, and unoccupied women have, at the same time, more over- and under-use for Pap test. Foreigner women reporting economic difficulties and single women have more mammography over and under-use. CONCLUSIONS Pap test and, in a minor measure, mammography over-use are relevant in Italy, while large part of the population is still not covered.
A V0-ATPase-dependent apical trafficking pathway maintains the polarity of the intestinal absorptive membrane

ABSTRACT Intestine function relies on the strong polarity of intestinal epithelial cells and the array of microvilli forming a brush border at their luminal pole. Combining a genetic RNA interference (RNAi) screen with in vivo super-resolution imaging in the Caenorhabditis elegans intestine, we found that the V0 sector of the vacuolar ATPase (V0-ATPase) controls a late apical trafficking step, involving Ras-related protein 11 (RAB-11)+ endosomes and the N-ethylmaleimide-sensitive factor-attachment protein receptor (SNARE) synaptosome-associated protein 29 (SNAP-29), and is necessary to maintain the polarized localization of both apical polarity modules and brush border proteins. We show that the V0-ATPase pathway also genetically interacts with glycosphingolipids and clathrin in enterocyte polarity maintenance. Finally, we demonstrate that silencing of the V0-ATPase fully recapitulates the severe structural, polarity and trafficking defects observed in enterocytes from individuals with microvillus inclusion disease (MVID) and use this new in vivo MVID model to follow the dynamics of microvillus inclusions. Thus, we describe a new function for V0-ATPase in apical trafficking and epithelial polarity maintenance and the promising use of the C. elegans intestine as an in vivo model to better understand the molecular mechanisms of rare genetic enteropathies. Highlighted Article: V0-ATPase controls a late apical trafficking step involved in the maintenance of the apical absorptive intestinal membrane and its silencing phenocopies microvillus inclusion disease in C. elegans.
Association between the BHMT gene rs3733890 polymorphism and the efficacy of oral folate therapy in patients with hyperhomocysteinemia

Oral folate is currently the most common treatment for hyperhomocysteinemia (HHcy), which seriously threatens human health, but its efficacy is unsatisfactory. Betaine‐homocysteine methyltransferase (BHMT) is a key enzyme that regulates Hcy metabolism. We investigated the association between the BHMT rs3733890 and the efficacy of oral folate therapy for HHcy in the Chinese Han population and analysed the effects of gene–environmental interactions on the efficacy. Blood samples were collected from 1071 eligible patients at baseline, and these individuals received subsequent folate treatment for 90 days. A total of 638 patients included in the final analysis were grouped into the treatment success group or the treatment failure group based on posttreatment Hcy levels. Hcy concentrations were measured by fluorescence polarization immunoassay. Time‐of‐flight mass spectrometry (MassArray system) was used to assess the genotype of BHMT rs3733890. Stratified analyses based on additive models and generalized multifactor dimensionality reduction were used to explore gene–environmental interactions. The genotype distribution presented distinct differences in the two groups. The mutant genotype and allele had significantly increased risk of treatment failure (p < 0.05). Furthermore, synergistic effects of the BHMT rs3733890 polymorphism with environmental risk factors (smoking, drinking, past history) on the efficacy of therapy were also found. However, future, large well‐designed studies, as well as mechanistic studies, are still needed to validate our findings.
Spatiotemporal Heterogeneity in the Distribution of Chikungunya and Zika Virus Case Incidences during their 2014 to 2016 Epidemics in Barranquilla, Colombia

Chikungunya virus (CHIKV) and Zika virus (ZIKV) have recently emerged as globally important infections. This study aimed to explore the spatiotemporal heterogeneity in the occurrence of CHIKV and ZIKV outbreaks throughout the major international seaport city of Barranquilla, Colombia in 2014 and 2016 and the potential for clustering. Incidence data were fitted using multiple Bayesian Poisson models based on multiple explanatory variables as potential risk factors identified from other studies and options for random effects. A best fit model was used to analyse their case incidence risks and identify any risk factors during their epidemics. Neighbourhoods in the northern region were hotspots for both CHIKV and ZIKV outbreaks. Additional hotspots occurred in the southwestern and some eastern/southeastern areas during their outbreaks containing part of, or immediately adjacent to, the major circular city road with its import/export cargo warehouses and harbour area. Multivariate conditional autoregressive models strongly identified higher socioeconomic strata and living in a neighbourhood near a major road as risk factors for ZIKV case incidences. These findings will help to appropriately focus vector control efforts but also challenge the belief that these infections are driven by social vulnerability and merit further study both in Barranquilla and throughout the world’s tropical and subtropical regions.
UV Sensitivity of MOS Structures with Silicon Nanoclusters

Selective UV sensitivity was observed in Metal-Oxide-Semiconductor structures with Si nanoclusters. Si nanocrystals and amorphous Si nanoparticles (a-Si NPs) were obtained by furnace annealing of SiOx films with x = 1.15 for 60 min in N2 at 1000 and 700 °C, respectively. XPS and TEM analysis prove phase separation and formation of Si nanocrystals in SiO2, while the a-Si NPs are formed in SiO1.7 matrix. Both types of structures show selective sensitivity to UV light; the effect is more pronounced in the structure with nanocrystals. The responsivity of the nanocrystal structure to 365 nm UV light is ~ 4 times higher than that to green light at 4 V applied to the top contact. The observed effect is explained by assuming that only short wavelength radiation generates photocarriers in the amorphous and crystalline nanoclusters.
Hosts for Hostile Protein Production: The Challenge of Recombinant Immunotoxin Expression

For the recombinant expression of toxin-based drugs, a crucial step lies not only in the choice of the production host(s) but also in the accurate design of the protein chimera. These issues are particularly important since such products may be toxic to the expressing host itself. To avoid or limit the toxicity to productive cells while obtaining a consistent yield in chimeric protein, several systems from bacterial to mammalian host cells have been employed. In this review, we will discuss the development of immunotoxin (IT) expression, placing special emphasis on advantages and on potential drawbacks, as one single perfect host for every chimeric protein toxin or ligand does not exist.
