title: Condensin-mediated chromosome folding and internal telomeres drive dicentric severing by cytokinesis

description: Preferential breakage of dicentric chromosomes at telomere fusions backs up in yeast the essential protective function of telomeres. Guérin et al. show that this rescue pathway depends on tight Rap1 DNA-binding at the fusion and condensin-dependent dicentric refolding prior to DNA breakage at the abscission site.

title: Supplementary Material for: Psychological Interventions for Adult Post-Traumatic Stress Disorder Are Effective Irrespective of Concurrent Psychotropic Medication Intake: A Meta-Analysis of Randomized Controlled Trials

description: <b><i>Background:</i></b> Participants are allowed to stay on their prescribed psychotropic medication in most trials examining psychological interventions for adult post-traumatic stress disorder (PTSD). <b><i>Objectives:</i></b> We aimed to conduct the first meta-analysis investigating the potential influence of such concurrent medication on efficacy. <b><i>Method:</i></b> To this end, we searched Medline, PsycINFO, Web of Science, and PTSDpubs from inception to April 21, 2022, for trials meeting the following criteria: (1) randomized controlled trial (RCT), (2) PTSD as primary treatment focus, (3) interview-based PTSD baseline rate ≥70%, (4) <i>N</i> ≥ 20, (5) mean age ≥18 years. Trials were excluded when intake of psychotropics was not (sufficiently) reported. <b><i>Results:</i></b> Most published trials did not report on the intake of psychotropic medication. A total of 75 RCTs (<i>N</i> = 4,901 patients) met inclusion criteria. Trauma-focused cognitive behavior therapy (TF-CBT) was the most well-researched intervention. Short-term efficacy of psychological treatments did not differ by the proportion of participants taking concurrent psychotropic medication during psychological treatment in all but one analysis. In trials comparing TF-CBT and active control conditions at posttreatment, TF-CBT was more effective when most participants were concurrently medicated (<i>g</i> = 0.87, 95% CI 0.53–1.22) rather than unmedicated (<i>g</i> = 0.27; 95% CI 0.01–0.54, <i>p</i> = 0.017), with younger age (<i>b</i><sub>1</sub> = −0.04, <i>p</i> = 0.008) and higher proportion of females (<i>b</i><sub>1</sub> = 0.01, <i>p</i> = 0.014) being associated with higher efficacy only in trials with high proportions of medicated participants. No differences in efficacy by proportions of participants taking concurrent psychotropic medication were found at follow-up. <b><i>Conclusions:</i></b> Results suggest that psychological interventions are effective for PTSD irrespective of concurrent intake of psychotropics.

title: Supplementary Material for: Oral Ibuprofen Is More Effective than Intravenous Ibuprofen for Closure of a Patent Ductus Arteriosus: Can Pharmacokinetic Modeling Help Us to Understand Why?

description: <b><i>Introduction:</i></b> Oral ibuprofen is more effective than intravenous (IV) ibuprofen for closure of a patent ductus arteriosus (PDA). This study explored whether higher concentrations of the biologically active S-enantiomer or increased R- to S-conversion following oral dosing could explain this finding. <b><i>Methods:</i></b> Two datasets containing 370 S- and R-ibuprofen concentrations from 95 neonates with PDA treated with oral (<i>n</i> = 27, 28%) or IV ibuprofen were analyzed using nonlinear mixed effects modeling. Concentration-time profiles in typical neonates were explored and compared in different dosing or R- to S-conversion scenarios. <b><i>Results:</i></b> Postnatal age (PNA), gestational age (GA), and being small for GA impacted S- and R-ibuprofen clearance. Upon oral dosing, S-ibuprofen concentrations were lower compared to IV ibuprofen for a large part of the dosing interval. We could show that R- to S-conversion will not exceed 45%. Exploration of a 30% presystemic R- to S-conversion resulted in a 25–32% increase in S-ibuprofen exposure following oral administration with AUC<sub>72h</sub> values varying between 700–2,213 mg*h/L (oral) and 531–1,762 (IV) for the standard or 1,704–2,893 (oral) and 1,295–2,271 mg*h/L (IV) for PNA-based dosing. <b><i>Discussion:</i></b> The absence of higher S-ibuprofen concentrations does not support a beneficial concentration-time profile after oral dosing. While a fraction of up to 45% presystemic R- to S-conversion could not be ruled out, the impact of such a low conversion might be only relevant for the standard but not high dosing regimens, considering reported exposure-response targets. Perhaps, the lack of high peak concentrations observed following IV dosing may play a role in the observed effects upon oral dosing.

title: Supplementary Material for: Aminotransferase Level and the Effects of Dual Antiplatelet in Minor Stroke or Transient Ischemic Attack: A post hoc Analysis of a Randomized Control Trial

description: <b><i>Introduction:</i></b> This study was intended to evaluate whether the safety and efficacy of dual antiplatelet treatment in patients with minor ischemic stroke (MIS) or transient ischemic attack (TIA) could be modified by the aminotransferase level. Also, we sought to assess the interaction between aminotransferase level and CYP2C19 loss-of-function status on the efficacy of dual antiplatelet therapy. <b><i>Methods:</i></b> This study is a post hoc analysis of the Clopidogrel in High-Risk Patients With Acute Nondisabling Cerebrovascular Events (CHANCE) study, a double-blinded randomized control trial. We included 5,133 patients with a complete workup of baseline alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. The primary outcome is stroke or TIA recurrence within 90 days. Cox proportional hazard models were used in the evaluation of the efficacy of antiplatelet treatment in patients with different aminotransferase levels and subgroups categorized by the aminotransferase level × CYP2C19 loss-of-function status. <b><i>Results:</i></b> The median age of all the included patients was 62 years; 66.3% of the patients were male. More recurrent stroke or TIA occurred in patients with elevated ALT and AST levels within 90 days compared to patients with normal ALT and AST levels (14.5 vs. 11.2%, <i>p</i> = 0.029). Dual antiplatelet treatment with aspirin and clopidogrel reduced recurrence compared with aspirin alone in patients with both normal (adjusted hazard ratio [HR], 95% confidence interval [CI]: 0.72 [0.60–0.86], <i>p</i> &lt; 0.001) and elevated (adjusted HR [95% CI]: 0. 57 [0. 35–0. 92], <i>p</i> = 0. 020) ALT and AST levels (<i>p</i> = 0.64 for interaction). No significant difference in treatment efficacy on 90-day all-cause death or bleeding events was found. <b><i>Conclusions:</i></b> Dual antiplatelet treatment was safe for minor stroke or high-risk TIA patients with mildly elevated aminotransferase. Mild elevation of ALT or AST did not undermine the protective efficacy of the dual antiplatelet regimen in reducing recurrent stroke or TIA within 90 days after MIS or TIA. The interaction between the CYP2C19 loss-of-function allele carrier status and aminotransferase level on the efficacy of dual antiplatelet treatment was not observed.

title: Supplementary Material for: Patterns of Respiratory Support by Gestational Age in Very Preterm Infants

description: <b><i>Introduction:</i></b> A detailed understanding of respiratory support patterns in preterm infants is lacking. The aim was to explore and visualize this practice in Sweden. <b><i>Methods:</i></b> Preterm infants with gestational ages of 22–31 weeks, admitted to neonatal units reporting daily to the Swedish Neonatal Quality Register and discharged alive in November 2015–April 2022, were included in this descriptive cohort study. Proportions receiving mechanical ventilation, noninvasive support, or supplemental oxygen were calculated and graphically displayed for each gestational week and postnatal day (range 0–97) up to hospital discharge or 36 weeks of postmenstrual age. <b><i>Results:</i></b> Respiratory support in 148,515 days of care (3,368 infants; 54% males; median [interquartile range] birthweight = 1,215 [900–1,525] g) was evaluated. Trajectories showed distinct nonlinear patterns for each category of respiratory support, but differences in respiratory support over the gestational age range were linear: the proportion of infants on mechanical ventilation decreased by −11.7 to −7.3% (variability in estimates related to the postnatal day chosen for regression analysis) for each week higher gestational age (<i>r</i> = −0.99 to −0.87, <i>p</i> ≤ 0.001). The corresponding proportions of infants with supplemental oxygen decreased by −12.4% to −4.5% for each week higher gestational age (<i>r</i> = −0.98 to −0.94, <i>p</i> &lt; 0.001). At 36 weeks of postmenstrual age, dependencies on mechanical ventilation, noninvasive support, and supplemental oxygen varied from 3%, 84%, and 94% at 22 weeks to 0%, 3%, and 5% at 31 weeks of gestational age, respectively. <b><i>Conclusions:</i></b> Respiratory support patterns in very preterm infants follow nonlinear, gestational age-specific postnatal trajectories in a dose-response-related fashion.

title: ALEX17 high-resolution, digital information of topography, surface and aerodynamic roughness of the experimental domain

description: The present dataset is part of the Alaiz Experiment-2017 (ALEX17). The information is divided into two groups based on their source. 1)Two raster-tpye geotif files containing the Digital Elevation and Digital Surface Models (DEM and DSM) data of the ALEX17 domain. The models were built by TRACASA ( https://tracasa.es/all-about-us/) which is a company part of the Navarra Government. The original dataset is cropped to fit the ALEX17 experimental domain with the following spatial coverage: 607700, 4720300 628010, 4738800 The datasets are generated through lidar airborne scans taken during years 2011 and 2012 and updated by photogrammetry with orthophotos of year 2014. The original lidar scans (2011-2012) have a density of 1pnt/m^2 . The raw data are then processed and converted to orthometric heights (from the original ellipsoidal heights ) and later projected into a 2x2m grid with spatial reference EPSG:25830. The conversion from ellipsoidal to orthometric height is carried out with the EGM2008_REDNAP model, generated by the Spanish Geographic National Institute available in: ftp://ftp.geodesia.ign.es/geoide/ 2)The second dataset is also a raster-type file which contains the approximate annual mean of aerodynamic roughness length in meters. The maps was created with two data sources: Visual estimation of the roughness length values & zones. The Corine Land Cover (CLC) 2006 data. 2.1) The visual estimations of roughness values w carried out with the use of both, orthophotos gathered from the National Geographic Institute of Spain (IGN) as well as site visits. These values were assigned to the Alaiz mountain region while the 2.2) CLC-derived roughness was set to the rest of the domain area. The orthophotos are obtained from the National Plan for Aerial Orthophotogrpy (PNOA) program (available at http://www.ign.es/ign/layoutIn/faimgsataerea.do ). These photos have a pixel size of 50cm and were taken in summer 2014. On the other hand, the Corine Land Cover (CLC) 2006 raster dataset have a 100 m grid size. These data are available at http://www.eea.europa.eu/data-and-maps/data/corine- land-cover-2006-raster-3 (g100_06.zip file). The roughness values were derived from the Land Cover data mostly based on the relation between CLC and the aerodynamic roughness length applied by the Finnish wind atlas (http://www.tuuliatlas.fi/modelling/mallinnus_3.html ). The final composed roughness raster map was built by interpolation (nearest-neighbor) of the two data sources onto a 10x10 meters grid . The map is also projected with the same spatial reference as the DEM/DSM data described above.

title: Significant demotivating factors affecting Saudi EFL Students: An Investigative Study with PYP students

description: The current study looks at the elements that impacted Saudi EFL students. 80 male and female students were the study's subjects, and a 50-item questionnaire was used to gather the data. Course instructor, course material, course facilities, attitude toward EFL, and sociocultural influences are the variables being studied. The SPSS program was used to analyze the data. The current study looks at the harmful elements to Saudi EFL learners. 80 male and female students were the study's subjects, and a 50-item questionnaire was used to gather the data. Course instructor, course material, course facilities, attitude toward EFL, and sociocultural influences are the variables being studied. The SPSS software has been used to examine the data. The ex-post facto design was used to carry out the current study. This study methodology was required because the researcher had no control over the choice and manipulation of the independent variables. This study included a deliberate sample of 35 females and 45 males. Prior verbal consent was gained for participation. Although it should be emphasized that soon after enrolling, they either dropped out of or failed the Intensive Course Program (ICP) of the Translation & English department in the College of Arts & Science, Al-Mithnab Al-Qassim University, KSA. The average age of the participants, who were all Saudi nationals, was 24. In order to uphold the research ethics, the confidentiality of information and participant identity concealment was guaranteed
