Effects of ACT Out! Social Issue Theater on Social-Emotional Competence and Bullying in Youth and Adolescents: Cluster Randomized Controlled Trial

Background: Schools increasingly prioritize social-emotional competence and bullying and cyberbullying prevention, so the development of novel, low-cost, and high-yield programs addressing these topics is important. Further, rigorous assessment of interventions prior to widespread dissemination is crucial. Objective: This study assesses the effectiveness and implementation fidelity of the ACT Out! Social Issue Theater program, a 1-hour psychodramatic intervention by professional actors; it also measures students' receptiveness to the intervention. Methods: This study is a 2-arm cluster randomized control trial with 1:1 allocation that randomized either to the ACT Out! intervention or control (treatment as usual) at the classroom level (n=76 classrooms in 12 schools across 5 counties in Indiana, comprised of 1571 students at pretest in fourth, seventh, and tenth grades). The primary outcomes were self-reported social-emotional competence, bullying perpetration, and bullying victimization; the secondary outcomes were receptiveness to the intervention, implementation fidelity (independent observer observation), and prespecified subanalyses of social-emotional competence for seventh- and tenth-grade students. All outcomes were collected at baseline and 2-week posttest, with planned 3-months posttest data collection prevented due to the COVID-19 pandemic. Results: Intervention fidelity was uniformly excellent (>96% adherence), and students were highly receptive to the program. However, trial results did not support the hypothesis that the intervention would increase participants' social-emotional competence. The intervention's impact on bullying was complicated to interpret and included some evidence of small interaction effects (reduced cyberbullying victimization and increased physical bullying perpetration). Additionally, pooled within-group reductions were also observed and discussed but were not appropriate for causal attribution. Conclusions: This study found no superiority for a 1-hour ACT Out! intervention compared to treatment as usual for social-emotional competence or offline bullying, but some evidence of a small effect for cyberbullying. On the basis of these results and the within-group effects, as a next step, we encourage research into whether the ACT Out! intervention may engender a bystander effect not amenable to randomization by classroom. Therefore, we recommend a larger trial of the ACT Out! intervention that focuses specifically on cyberbullying, measures bystander behavior, is randomized by school, and is controlled for extant bullying prevention efforts at each school.Funding for this study was provided by Lilly Endowment Inc, grant no. 2019 0543, to Claude McNeal Productions.

Helicobacter pylori Adapts to Chronic Infection and Gastric Disease via pH-Responsive BabA-Mediated Adherence

International audienceThe BabA adhesin mediates high-affinity binding of Helicobacter pylori to the ABO blood group antigen-glycosylated gastric mucosa. Here we show that BabA is acid responsive-binding is reduced at low pH and restored by acid neutralization. Acid responsiveness differs among strains; often correlates with different intragastric regions and evolves during chronic infection and disease progression; and depends on pH sensor sequences in BabA and on pH reversible formation of high-affinity binding BabA multimers. We propose that BabA's extraordinary reversible acid responsiveness enables tight mucosal bacterial adherence while also allowing an effective escape from epithelial cells and mucus that are shed into the acidic bactericidal lumen and that bio-selection and changes in BabA binding properties through mutation and recombination with babA-related genes are selected by differences among individuals and by changes in gastric acidity over time. These processes generate diverse H. pylori subpopulations, in which BabA's adaptive evolution contributes to H. pylori persistence and overt gastric disease

Expert range maps of global mammal distributions harmonised to three taxonomic authorities

AimComprehensive, global information on species' occurrences is an essential biodiversity variable and central to a range of applications in ecology, evolution, biogeography and conservation. Expert range maps often represent a species' only available distributional information and play an increasing role in conservation assessments and macroecology. We provide global range maps for the native ranges of all extant mammal species harmonised to the taxonomy of the Mammal Diversity Database (MDD) mobilised from two sources, the Handbook of the Mammals of the World (HMW) and the Illustrated Checklist of the Mammals of the World (CMW).LocationGlobal.TaxonAll extant mammal species.MethodsRange maps were digitally interpreted, georeferenced, error-checked and subsequently taxonomically aligned between the HMW (6253 species), the CMW (6431 species) and the MDD taxonomies (6362 species).ResultsRange maps can be evaluated and visualised in an online map browser at Map of Life (mol.org) and accessed for individual or batch download for non-commercial use.Main conclusionExpert maps of species' global distributions are limited in their spatial detail and temporal specificity, but form a useful basis for broad-scale characterizations and model-based integration with other data. We provide georeferenced range maps for the native ranges of all extant mammal species as shapefiles, with species-level metadata and source information packaged together in geodatabase format. Across the three taxonomic sources our maps entail, there are 1784 taxonomic name differences compared to the maps currently available on the IUCN Red List website. The expert maps provided here are harmonised to the MDD taxonomic authority and linked to a community of online tools that will enable transparent future updates and version control

Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples

Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

Naloxone availability and dispensing in Indiana pharmacies 2 years after the implementation of a statewide standing order

Objectives: This study examined changes in rates of pharmacy naloxone stocking and dispensing in Indiana between 2016 and 2018 and explored supplemental variables and factors that may have affected observed differences. Methods: Researchers used data from 2 existing datasets that were collected from managing pharmacists who responded to statewide pharmacy censuses in 2016 and 2018. After identifying all cases in which a pharmacy's managing pharmacist responded in both 2016 and 2018 censuses, researchers conducted a nonparametric statistical comparison of naloxone stocking and dispensing rates in 107 Indiana pharmacies. Additional descriptive data regarding naloxone-related pharmacy policies and educational programs during those years were collected in 2019 from pharmacy corporations operating food stores or chain pharmacies in Indiana and from the Indiana Pharmacists Association. Results: Pharmacy stocking and dispensing in Indiana increased from 2016 to 2018. In 2016, 57% of pharmacies reported stocking naloxone compared with 92.5% in 2018 (P < 0.001). Similarly, 23.4% of pharmacies reported dispensing naloxone in 2016 compared with 76.6% of pharmacies in 2018 (P < 0.001). All responding pharmacy corporations and the state pharmacy association reported offering self-directed volunteer-training programs regarding naloxone since 2016. In addition, they reported that company policy and procedures regarding naloxone were put into place in response to the 2016 statewide standing order. Conclusion: Pharmacy naloxone stocking and dispensing increased in the 2 years after the statewide standing order was issued. The effect of the order itself was likely moderated or mediated by corporate responses to the law. Research examining the impact of naloxone-availability policies on pharmacy practice and patient incomes should longitudinally examine data after policy implementation and with covariates that include type of pharmacy (e.g., chain or independent), location, and opioid overdose-associated mortality rates.

Relationship Between Substance Use and the Onset of Spinal Cord Injuries: A Medical Chart Review

Background: Opioid misuse is a leading health care concern within the United States. In many cases, opioid misuse and opioid use disorder are associated with pain, a secondary health condition affecting individuals with spinal cord injury (SCI). Further, substance use is a known risk factor for SCI, resulting in the potential for a substance-related risk trajectory running from pre- to post-SCI. However, little research has examined substance use prior to SCI since the opioid epidemic began, and so the relative risk of opioids to patients with SCI is unclear. Objective: To determine whether individuals with SCI tested positive for substance use at the time of injury and identify the primary substances used at the time of injury. Methods: This study retrospectively reviewed all medical charts of individuals ages 18 and older who had sustained an SCI during an identified 18-month period and received medical care at a selected level 1 trauma center in the Midwest. Results: Data revealed an 80% combined positive toxicology and/or self-report of substance use immediately prior to the onset of the SCI. Twenty-five percent of males were positive for more than one substance at time of injury. Substances used prior to injury, listed most to least prevalent, were opioids (37.5%), alcohol (25%), marijuana (25%), methamphetamines (12.5%), benzodiazepines (12.5%), followed by cocaine (6.25%) and synthetic cathinone (6.25%). Conclusion: Although opioids were the most common substance used prior to SCI, none of the individuals positive for opioids at the time of injury were identified by the reviewing medical professional as having pain as a secondary health condition either prior to or after injury. However, pain is commonly listed as the primary health concern among individuals living with SCI, and the possibility of opioid use prior to injury likely warrants pain management planning that includes careful pharmacological and nonpharmacological interventions
