The bone marrow microenvironment of pre-B acute lymphoblastic leukemia at single-cell resolutionThe bone marrow microenvironment plays a key role in leukemia progression, but its molecular complexity in pre-B cell acute lymphoblastic leukemia (B-ALL), the most common cancer in children, remains poorly understood. To gain further insight, we used single-cell RNA sequencing to characterize the kinetics of the murine BMM during B-ALL progression.

Maternal prenatal stress exposure and sex-specific risk of severe infection in offspringMaternal stressful life events during pregnancy have been associated with immune dysregulation and increased risk for asthma and atopy in offspring. Few studies have investigated whether prenatal stress is associated with increased overall or specific infectious diseases in childhood, nor explored sex differences. We sought to examine the relationship between the nature and timing of maternal stress in pregnancy and hospitalisation with infection in offspring.

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.

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.

The impact of maternal prenatal mental health disorders on stillbirth and infant mortality: a systematic review and meta-analysisEvidence about the association between maternal mental health disorders and stillbirth and infant mortality is limited and conflicting. We aimed to examine whether maternal prenatal mental health disorders are associated with stillbirth and/or infant mortality. MEDLINE, Embase, PsycINFO, and Scopus were searched for studies examining the association of any maternal prenatal (occurring before or during pregnancy) mental health disorder(s) and stillbirth or infant mortality. A random-effects meta-analysis was used to calculate pooled odds ratios (ORs) with 95% confidence intervals (CIs). The between-study heterogeneity was quantified using the I2 statistic. Subgroup analyses were performed to identify the source of heterogeneity.
