Examining the Errors and Self-Corrections on the Stroop Test

The purpose of this study was to collect normative data for a computer-assisted version of the Comalli Stroop Test, a commonly used neuropsychological measure. Additionally, the study was aimed at investigating the self-corrected errors on the Stroop Test, which have not previously been accounted for on the traditional test versions. Participants included one hundred and seventy two individuals from Cleveland State University and the community. Participants were administered computer-assisted versions of the Comalli Stroop Test and Trail Making Test. Participants were also asked to rate their agreement to four statements on a 5-level Likert scale to assess self-perceptions of testing. Errors, self-corrected errors, and time of completion for both tasks were recorded. Answers to the Self-Monitoring Scale were scored and recorded. The results of this study show that age and education both affected the quantity and location of errors and self-corrected errors on the Stroop Test. The Trail Making Test, which was used to validate the errors on the Stroop Test, showed a similar pattern of location of errors to the Stroop Test. Errors were frequently made in the middle to later portions of these tests, whereas self-corrections were made in the earlier portions. This pattern is partially due to participants\u27 limited cognitive and attention resources as the tests progress. The results of this study suggest that self-corrections are measuring a separate construct than errors on the Stroop Test. The ability to self-correct on the Stroop Test is a sign of mental health, flexibility, and ability to self-monitor. Utilizing the self-corrected errors on the Stroop Test gives test administrators an additional tool in detecting control, and higher mental processes. Also, the results demonstrate that errors are measuring a separate construct than time of completion. The traditional approach to neuropsychological testing examines the total number of errors and time of completion for the entire task, rather than examining the criti

Interventions for Infection and Inflammation-Induced Preterm Birth: a Preclinical Systematic Review

Spontaneous preterm births (< 37 weeks gestation) are frequently associated with infection. Current treatment options are limited but new therapeutic interventions are being developed in animal models. In this PROSPERO-registered preclinical systematic review, we aimed to summarise promising interventions for infection/inflammation-induced preterm birth. Following PRISMA guidance, we searched PubMed, EMBASE, and Web of Science using the themes: "animal models", "preterm birth", "inflammation", and "therapeutics". We included original quantitative, peer-reviewed, and controlled studies applying prenatal interventions to prevent infection/inflammation-induced preterm birth in animal models. We employed two risk of bias tools. Of 4020 identified studies, 23 studies (24 interventions) met our inclusion criteria. All studies used mouse models. Preterm birth was most commonly induced by lipopolysaccharide (18 studies) or Escherichia coli (4 studies). Models varied according to infectious agent serotype, dose, and route of delivery. Gestational length was significantly prolonged in 20/24 interventions (83%) and markers of maternal inflammation were reduced in 20/23 interventions (87%). Interventions targeting interleukin-1, interleukin-6, and toll-like receptors show particular therapeutic potential. However, due to the heterogeneity of the methodology of the included studies, meta-analysis was impossible. All studies were assigned an unclear risk of bias using the SYRCLE risk of bias tool. Interventions targeting inflammation demonstrate therapeutic potential for the prevention of preterm birth. However, better standardisation of preterm birth models, including the dose, serotype, timing of administration and pathogenicity of infectious agent, and outcome reporting is urgently required to improve the reproducibility of preclinical studies, allow meaningful comparison of intervention efficacy, and aid clinical translation

Efficacy and Safety of Ciprofloxacin for Prophylaxis of Polyomavirus BK Virus–Associated Hemorrhagic Cystitis in Allogeneic Hematopoietic Stem Cell Transplantation Recipients

Polyoma virus BK–induced hemorrhagic cystitis is an important cause of morbidity after hematopoietic stem cell transplantation (HSCT). Fluoroquinolones have been shown in vitro to inhibit BK viral replication by direct inhibition of the BK-encoded DNA gyrase. We hypothesized that extended prophylaxis with ciprofloxacin may decrease the incidence of severe (grades 3 and 4) BK virus–associated hemorrhagic cystitis (sBKHC) after HSCT. We retrospectively collected patient and transplant data, as well as incidence of sBKHC, for all consecutive patients undergoing allogeneic HSCT between June 2006 and August 2010 at our institution. Prophylaxis for sBKHC with ciprofloxacin 500 mg orally twice daily from day 0 until day 60 had been instituted in March 2009, delimiting a group receiving ciprofloxacin prophylaxis (CP) or no prophylaxis (NP). We compared the cumulative incidence of sBKHC in CP and NP, including death in absence of sBKHC as a competing risk. Ninety-two consecutive patients were included in the analysis, 44 in CP and 48 in NP. Median age of patients was 50 years (range: 19-70), and 47% received a myeloablative conditioning regimen. The cumulative incidence of sBKHC was significantly reduced in CP (2.6% versus 20.9%, P = .01). Multivariate Cox regression analysis revealed that assignment to CP and concomitant acute graft-versus-host disease (GVHD) were the only factors independently associated with the occurrence of sBKHC. Patients in CP did not experience a higher risk of Clostridium difficile diarrhea and were less likely to develop episodes of bacteremia. Ciprofloxacin prophylaxis appears safe and effective in reducing the incidence of severe BKHC after allogeneic HSCT

Spectral and Timing Properties of IGR J17091-3624 in the Rising Hard State During its 2016 Outburst

We present a spectral and timing study of the NuSTAR and Swift observations of the black hole candidate IGR J17091-3624 in the hard state during its outburst in 2016. Disk reflection is detected in each of the NuSTAR spectra taken in three epochs. Fitting with relativistic reflection models reveals that the accretion disk is truncated during all epochs with $R_{\rm in}>10~r_{\rm g}$, with the data favoring a low disk inclination of $\sim 30^{\circ}-40^{\circ}$. The steepening of the continuum spectra between epochs is accompanied by a decrease in the high energy cut-off: the electron temperature $kT_{\rm e}$ drops from $\sim 64$ keV to $\sim 26$ keV, changing systematically with the source flux. We detect type-C QPOs in the power spectra with frequency varying between 0.131 Hz and 0.327 Hz. In addition, a secondary peak is found in the power spectra centered at about 2.3 times the QPO frequency during all three epochs. The nature of this secondary frequency is uncertain, however a non-harmonic origin is favored. We investigate the evolution of the timing and spectral properties during the rising phase of the outburst and discuss their physical implications.Comment: 11 pages, 9 figures, accepted by Ap

Disordered eating and eating disorders among women seeking fertility treatment: A systematic review

The purpose of this systematic review is to evaluate the prevalence of disordered eating and eating disorders among women seeking fertility treatment. Observational studies were searched in Ovid MEDLINE, Web of Science, Embase, and PsycInfo. Studies published prior to September 2020 when the search was conducted were considered. Inclusion criteria included (1) original and empirical research, (2) published in a peer-reviewed journal, and (3) reported on disordered eating among women seeking fertility treatment in the sample or reported on prevalence of eating disorders among women seeking fertility treatment in the sample. Independent screening of abstracts was conducted by two authors (LH and AH). Ten studies met the inclusion criteria. Sample size, study location, measures, and results for each study in this review were reported. Among women pursuing fertility treatment, rates of current eating disorders ranged from 0.5 to 16.7%, while past eating disorder prevalence rates ranged from 1.4 to 27.5%. Current anorexia nervosa or bulimia nervosa was reported by up to 2% and 10.3% of women, respectively, while history of anorexia nervosa or bulimia nervosa was reported by up to 8.5% and 3.3% of women, respectively. Binge eating disorder or other eating disorders were reported by up to 18.5% and 9.1% of women, respectively. Disordered eating pathology was endorsed by 1.6 to 48% of women seeking fertility treatment. Endorsement of pathological eating attitudes was generally higher among women seeking fertility treatment with current or past eating disorders as compared to community samples, with the exception of dietary restraint. Rates of current and past eating disorders are higher among women seeking fertility treatment than in the general population. Providers treating women with infertility should be cognizant of these prevalence rates and consider screening for eating pathology in their patients as this may contribute to their likelihood of successful conception and/or subsequent pregnancy outcomes

A NuSTAR observation of the reflection spectrum of the low mass X-ray binary 4U 1728-34

We report on a simultaneous NuSTAR and Swift observation of the neutron star low-mass X-ray binary 4U 1728-34. We identified and removed four Type I X-ray bursts during the observation in order to study the persistent emission. The continuum spectrum is hard and well described by a black body with $kT=$ 1.5 keV and a cutoff power law with $\Gamma=$ 1.5 and a cutoff temperature of 25 keV. Residuals between 6 and 8 keV provide strong evidence of a broad Fe K$\alpha$ line. By modeling the spectrum with a relativistically blurred reflection model, we find an upper limit for the inner disk radius of $R_{\rm in}\leq2 R_{\rm ISCO}$. Consequently we find that $R_{\rm NS}\leq23$ km, assuming M=1.4{\mbox{\rm\,M_{\mathord\odot}}} and $a=0.15$. We also find an upper limit on the magnetic field of $B\leq2\times10^8$ G.Comment: 9 pages, 8 figure

A Longitudinal Study of Pediatricians Early in their Careers: PLACES

The American Academy of Pediatrics (AAP) launched the Pediatrician Life and Career Experience Study (PLACES), a longitudinal study that tracks the personal and professional experiences of early career pediatricians, in 2012. We used a multipronged approach to develop the study methodology and survey domains and items, including review of existing literature and qualitative research with the target population. We chose to include 2 cohorts of US pediatricians on the basis of residency graduation dates, including 1 group who were several years out of residency (2002–2004 Residency Graduates Cohort) and a second group who recently graduated from residency at study launch (2009–2011 Residency Graduates Cohort). Recruitment into PLACES was a 2-stage process: (1) random sample recruitment from the target population and completion of an initial intake survey and (2) completion of the first Annual Survey by pediatricians who responded positively to stage 1. Overall, 41.2% of pediatricians randomly selected to participate in PLACES indicated positive interest in the study by completing intake surveys; of this group, 1804 (93.7%) completed the first Annual Survey and were considered enrolled in PLACES. Participants were more likely to be female, AAP members, and graduates of US medical schools compared with the target sample; weights were calculated to adjust for these differences. We will survey PLACES pediatricians 2 times per year. PLACES data will allow the AAP to examine career and life choices and transitions experienced by early-career pediatricians

Neonatal face-to-face interactions promote later social behaviour in infant rhesus monkeys

In primates, including humans, mothers engage in face-to-face interactions with their infants, with frequencies varying both within and across species. However, the impact of this variation in face-to-face interactions on infant social development is unclear. Here we report that infant monkeys (Macaca mulatta) who engaged in more neonatal face-to-face interactions with mothers have increased social interactions at 2 and 5 months. In a controlled experiment, we show that this effect is not due to physical contact alone: monkeys randomly assigned to receive additional neonatal face-to-face interactions (mutual gaze and intermittent lip-smacking) with human caregivers display increased social interest at 2 months, compared with monkeys who received only additional handling. These studies suggest that face-to-face interactions from birth promote young primate social interest and competenc
