Assessment of different techniques for the administration of inhaled salbutamol in children breathing spontaneously via tracheal tubes, supraglottic airway devices, and tracheostomiesPerioperative respiratory adverse events account for a third of all perioperative cardiac arrests, with bronchospasm and laryngospasm being most common. Standard treatment for bronchospasm is administration of inhaled salbutamol, via pressurized metered dose inhaler. There is little evidence on the best method of attaching the pressurized metered dose inhaler to the artificial airway during general anesthesia. The aim of this study is to investigate the best method to deliver aerosolized salbutamol via pressurized metered dose inhaler to the lungs of an anesthetized child.

Health and climate change MJA–Lancet Countdown report: Australia gets another failing grade in 2020 but shows signs of progressAt the end of 2019 and into 2020, catastrophic fires in Australia consumed homes, lives, wildlife, and land. Just as the fires subsided, Australia, like the rest of the world, faced another emergency—the COVID-19 pandemic. It is instructive to reflect on lessons from the health disasters of the past year. Following publication of the Lancet Countdown on Health and Climate Change, the Medical Journal of Australia (MJA)–Lancet Australian Countdown was published in December, 2020. This annual report on health and climate change in Australia is in its third year and comprises the efforts of five Australian institutions, in collaboration with University College London, UK, facilitated by a partnership between The Lancet and the MJA.

Aging of preleukemic thymocytes drives CpG island hypermethylation in T-cell acute lymphoblastic leukemiaCancer cells display DNA hypermethylation at specific CpG islands in comparison to their normal healthy counterparts, but the mechanism that drives this so-called CpG island methylator phenotype (CIMP) remains poorly understood. Here, we show that CpG island methylation in human T-cell acute lymphoblastic leukemia (T-ALL) mainly occurs at promoters of Polycomb Repressor Complex 2 (PRC2) target genes that are not expressed in normal or malignant T-cells and which display a reciprocal association with H3K27me3 binding.

ACE2 expression is elevated in airway epithelial cells from older and male healthy individuals but reduced in asthmaCOVID-19 is complicated by acute lung injury, and death in some individuals. It is caused by SARS-CoV-2 that requires the ACE2 receptor and serine proteases to enter AEC. We determined what factors are associated with ACE2 expression particularly in patients with asthma and COPD. We obtained lower AEC from 145 people from two independent cohorts, aged 2-89 years, Newcastle (n = 115) and Perth (n = 30), Australia. The Newcastle cohort was enriched with people with asthma (n = 37) and COPD (n = 38). Gene expression for ACE2 and other genes potentially associated with SARS-CoV-2 cell entry was assessed by qPCR, and protein expression was confirmed with immunohistochemistry on endobronchial biopsies and cultured AEC.

Mode of birth and risk of infection-related hospitalisation in childhood: A population cohort study of 7.17 million births from 4 high-income countriesThe proportion of births via cesarean section (CS) varies worldwide and in many countries exceeds WHO-recommended rates. Long-term health outcomes for children born by CS are poorly understood, but limited data suggest that CS is associated with increased infection-related hospitalisation. We investigated the relationship between mode of birth and childhood infection-related hospitalisation in high-income countries with varying CS rates.

Why do Victims become Perpetrators of Peer Bullying? Moral Disengagement in the Cycle of ViolencePrevious studies have shown that there is overlap between victimization and the perpetration of bullying, and social and motivational variables are known to mediate this relationship. However, the effects of different moral disengagement strategies have not been studied, despite the fact that they exert a major influence on aggressive behavior.

Study protocol for a randomised controlled trial evaluating the effect of folic acid supplementation beyond the first trimester on maternal plasma unmetabolised folic acid in late gestationTaking folic acid containing supplements prior to and during early pregnancy reduces the risk of neural tube defects. Neural tube defects occur prior to 28 days postconception, after which, there is no proven benefit of continuing to take folic acid. However, many women continue to take folic acid containing supplements throughout the pregnancy.
