With 40 million annual passenger flights, airports are key hubs for microbial communities from diverse geographic origins to converge, mix, and distribute. Wastewater derived from airports and aircraft represent both a potential route for the global dispersion of antimicrobial resistant (AMR) organisms and an under-utilised resource for strengthening global AMR surveillance. This study investigates the abundance and diversity of antimicrobial resistance genes (ARGs) in wastewater samples collected from airport terminals (n = 132), aircraft (n = 25), and a connected wastewater treatment plant (n = 11) at three international airports in the UK (London Heathrow, Edinburgh and Bristol).

Article Synopsis
  • - Wastewater contains significant information about antimicrobial resistance (AMR), and studying it can help inform public health policies, as seen in a comparative study of two screening methods for tracking AMR in Wales.
  • - The study compared high-throughput quantitative PCR (HT qPCR), which focused on 73 specific resistance genes, with metagenomic sequencing, which identified a broader range of 545 resistance genes and provided important context about potential bacterial hosts.
  • - While metagenomics offered a detailed overview of the resistome, HT qPCR was better at detecting and quantifying low-abundance genes relevant to clinical resistance; both methods showed similar trends related to environmental factors influencing AMR.

Pompe disease is a progressive myopathy resulting from deficiency in lysosomal enzyme acid α-glucosidase (GAA), which leads to glycogen accumulation in lysosomes primarily in skeletal and cardiac muscle. Enzyme replacement therapy (ERT) with recombinant human (rh) GAA works well in alleviating the cardiomyopathy; however, many patients continue to have progressive muscle weakness. The purpose of this study was to evaluate the effectiveness of a respiratory training combined with 24-week supervised resistance training program on muscle strength (measured by Biodex)), and respiratory function including maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) in subjects with late onset Pompe disease receiving ERT.

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by a deficiency in the enzyme α-galactosidase A due to mutations in the gene. This leads to an accumulation of globotriaosylceramide (GL-3) in many tissues, which results in progressive damage to the kidneys, heart, and nervous system. We present the molecular and clinical characteristics and long-term outcomes of FD patients from a multidisciplinary clinic at the University of California, Irvine treated with agalsidase beta enzyme replacement therapy (ERT) for 2-20 years.

Anthropogenic CO emissions are projected to lower the pH of the ocean 0.3 units by 2100. Previous studies suggested that Prochlorococcus and Synechococcus, the numerically dominant phytoplankton in the oceans, have different responses to elevated CO that may result in a dramatic shift in their relative abundances in future oceans.

There are a variety of causes of acute heart failure in children including myocarditis, genetic/metabolic conditions, and congenital heart defects. In cases with a structurally normal heart and a negative personal and family history, myocarditis is often presumed to be the cause, but we hypothesise that genetic disorders contribute to a significant portion of these cases. We reviewed our cases of children who presented with acute heart failure and underwent genetic testing from 2008 to 2017.

The prevalence of metabolic syndrome (MetS) in people with serious mental illness (SMI) has been well documented in the mental health literature. Despite the adoption of various guidelines for monitoring risk factors for diabetes and cardiovascular risk in this population, limited translation has occurred in actual practice (Hermes, Sernyak, & Rosenheck, 2013). The Institute of Medicine (IoM) (2009) has noted a lag time in the application of knowledge within clinical settings.
