ASD Symptoms, Social Skills, and Comorbidity: Predictors of Bullying Perpetration.

Children with ASD are more likely to be involved in bullying compared to typically developing peers; however, studies rarely examine bullying perpetration and the contributing factors among this population. The primary aim of this study was to examine the extent to which parent-reported ASD symptoms, social skills, and comorbid externalizing and internalizing symptoms predicted bullying perpetration in a sample of 390 children with ASD without intellectual disability. Findings from hierarchical regression analyses indicated that social skill deficits, externalizing symptoms (i.

Identifying low-risk chest pain in the emergency department without troponin testing: a validation study of the HE-MACS and HEAR risk scores.

Introduction: Patients presenting to EDs with chest pain of possible cardiac origin represent a substantial and challenging cohort to risk stratify. Scores such as HE-MACS (History and Electrocardiogram-only Manchester Acute Coronary Syndromes decision aid) and HEAR (History, ECG, Age, Risk factors) have been developed to stratify risk without the need for troponin testing. Validation of these scores remains limited.

Generation and transmission of interlineage recombinants in the SARS-CoV-2 pandemic.

We present evidence for multiple independent origins of recombinant SARS-CoV-2 viruses sampled from late 2020 and early 2021 in the United Kingdom. Their genomes carry single-nucleotide polymorphisms and deletions that are characteristic of the B.1.

Does venous thromboembolism prophylaxis affect the risk of venous thromboembolism and adverse events following primary hip and knee replacement? A retrospective cohort study.

Background: The optimum chemical venous thromboembolism (VTE) prophylactic agents following total hip and knee replacement (THR and TKR) remain unknown. NICE recommends multiple agents, including direct oral anticoagulants (DOACs), low-molecular weight heparin (LMWH), and aspirin. We assessed whether VTE prophylaxis affected the risk of VTE and adverse events following primary THR and TKR.
