Co-selection for antibiotic resistance by environmental contaminants.

The environment is increasingly recognised as a hotspot for the selection and dissemination of antibiotic resistant bacteria and antibiotic resistance genes. These can be selected for by antibiotics and non-antibiotic agents (such as metals and biocides), with the evidence to support this well established by observational and experimental studies. However, there is emerging evidence to suggest that plant protection products (such as herbicides), and non-antibiotic drugs (such as chemotherapeutic agents), can also co-select for antibiotic resistance.

Using primary and routinely collected data to determine prevalence and patterns of multimorbidity in rural China: a representative cross-sectional study of 6474 Chinese adults.

Background: In China, rising chronic diseases has coincided with the increasing burden of multimorbidity, particularly for vulnerable populations. Limited primary data are available to understand the prevalence and patterns of multimorbidity, especially in resource-limited rural areas. This study aims to conduct robust evaluations of the prevalence and patterns of multimorbidity among rural adults in China, and to compare the differences in prevalence and patterns when using primary data alone versus in combination with routinely collected data.

Antimicrobial risk assessment-Aggregating aquatic chemical and resistome emissions.

Urban water systems receive and emit antimicrobial chemicals, resistant bacterial strains, and resistance genes (ARGs), thus representing "antimicrobial hotspots". Currently, regional environmental risk assessment (ERA) is carried out using drug consumption data and threshold concentrations derived based on chemical-specific minimum inhibitory concentration values. A legislative proposal by the European Commission released in 2022 addresses the need to include selected ARGs besides the chemical concentration-based ERAs.

The direct and urinary electrolyte-mediated effects of ambient temperature on population blood pressure: A causal mediation analysis.

High ambient heat can directly influence blood pressure (BP) through the vasodilation of the skin vasculature and indirectly by affecting urinary volume and electrolyte levels. We evaluated the direct and urine electrolyte-mediated effects of ambient temperature on BP. We pooled 5,624 person-visit data from a community-based stepped-wedge randomized control trial in southwest coastal Bangladesh from December 2016 to May 2017.

The risk of childhood asthma across diverse climates: growing up in Australia.

This study investigates the association between climate and childhood asthma in Australia. Data from the Longitudinal Study of Australian Children (LSAC) was used to analyse this association in children who were 6-15 years between 2004 and 2018. Asthma prevalence decreased from 16% at 6-7 years to 13% at 14-15 years.

The role of greenspace in vitamin D status: cross-sectional, observational evidence from the UK Biobank.

Background: Exposure to greenspace is associated with positive health outcomes. This relationship is poorly understood, with limited knowledge on the mechanisms through which greenspace affects health, including biomarkers of greenspace effects.

Methods: We used data from the UK Biobank to examine the cross-sectional association between greenspace exposure and serum 25-hydroxyvitamin D [25(OH)D].

The role of healthcare professionals' attitudes in treatment decision-making for older adults with cancer: A scoping review.

Introduction: The global population of older adults with cancer is increasing, presenting care challenges caused by comorbidity, polypharmacy, and frailty. In response to these complexities, healthcare professionals (HCPs) rely on their own attitudes to a larger extent due to limitations in the treatment evidence for this population. This scoping review aims to explore and describe the attitudes of HCPs in the context of treatment decision-making for older adults with cancer.

Conjugation Mediates Large-Scale Chromosomal Transfer in Streptomyces Driving Diversification of Antibiotic Biosynthetic Gene Clusters.

Streptomyces are ubiquitous soil-dwelling bacteria with large, linear genomes that are of special importance as a source of metabolites used in human and veterinary medicine, agronomy, and industry. Conjugative elements (actinomycetes integrative and conjugative elements, AICEs) are the main drivers of Streptomyces Horizontal Gene Transfer. AICE transfer has long been known to be accompanied by mobilization of chromosomal DNA.

Air pollution and respiratory health in patients with COPD: should we focus on indoor or outdoor sources?

Introduction: While associations between ambient air pollution and respiratory health in chronic obstructive pulmonary disease (COPD) patients are well studied, little is known about individuals' personal exposure to pollution and associated health effects by source.

Aim: To separate measured total personal exposure into indoor-generated and outdoor-generated pollution and use these improved metrics in health models for establishing more reliable associations with exacerbations and respiratory symptoms.

Methods: We enrolled a panel of 76 patients with COPD and continuously measured their personal exposure to particles and gaseous pollutants and location with portable monitors for 134 days on average.

Re-thinking human interactions with the oceans.

Earth's marine ecosystems are changing rapidly, in large part owing to the damaging effects of human activities. Unless humans find better ways of interacting with the seas and oceans, the marine resources upon which we rely will diminish as more ecosystems collapse. The consequences for human health and wellbeing will be severe.

Why do mobile genetic elements transfer DNA of their hosts?

The prokaryote world is replete with mobile genetic elements (MGEs) - self-replicating entities that can move within and between their hosts. Many MGEs not only transfer their own DNA to new hosts but also transfer host DNA located elsewhere on the chromosome in the process. This could potentially lead to indirect benefits to the host when the resulting increase in chromosomal variation results in more efficient natural selection.

A critical meta-analysis of predicted no effect concentrations for antimicrobial resistance selection in the environment.

Antimicrobial resistance (AMR) is one of the greatest threats to human health with a growing body of evidence demonstrating that selection for AMR can occur at environmental antimicrobial concentrations. Understanding the concentrations at which selection for resistance may occur is critical to help inform environmental risk assessments and highlight where mitigation strategies are required. A variety of experimental and data approaches have been used to determine these concentrations.

Environmental protection is more important to European citizens of all political persuasions than economic growth: A 14-country study in the marine context.

To focus on voters' priorities, Bill Clinton's campaign famously used the slogan, "It's the economy stupid." With growing environmental crises, is this still true? We explored this issue for the marine sector, using representatively-weighted survey data from 14 European countries (N = 11,130). Citizens were asked about their own and policy makers' (perceived) preferences for marine-related economic, environmental, and human health policy goals.

Effect of chemotherapeutic agents on natural transformation frequency in Acinetobacter baylyi.

Natural transformation is the ability of a bacterial cell to take up extracellular DNA which is subsequently available for recombination into the chromosome (or maintenance as an extrachromosomal element). Like other mechanisms of horizontal gene transfer, natural transformation is a significant driver for the dissemination of antimicrobial resistance. Recent studies have shown that many pharmaceutical compounds such as antidepressants and anti-inflammatory drugs can upregulate transformation frequency in the model species .

Short-term air pollution and greenness exposures on oxidative stress in urban and peri-urban residents in Beijing: A part of AIRLESS study.

Background: Exposure to air pollution has been associated with increased risks of cardiopulmonary diseases, cancer, and mortality, whereas residing near green spaces may reduce the risks. However, limited research explores their combined effect on oxidative stress.

Methods: A total of 251 participants with multi-time measurements were included in the longitudinal-designed study.

Sex-Specific Association of Ambient Temperature With Urine Biomarkers in Southwest Coastal Bangladesh.

Introduction: Men are vulnerable to ambient heat-related kidney disease burden; however, limited evidence exists on how vulnerable women are when exposed to high ambient heat. We evaluated the sex-specific association between ambient temperature and urine electrolytes, and 24-hour urine total protein, and volume.

Methods: We pooled a longitudinal 5624 person-visits data of 1175 participants' concentration and 24-hour excretion of urine electrolytes and other biomarkers (24-hour urine total protein and volume) from southwest coastal Bangladesh (Khulna, Satkhira, and Mongla districts) during November 2016 to April 2017.

Greenspace and risk of obesity-related cancer in the UK Biobank cohort: An analysis of private residential gardens and other greenspace types.

Background: Cohort studies linking greenspace exposure to a lower risk of obesity-related cancer (ORC) are scarce. Existing evidence on site-specific cancers has predominantly relied on non-specific greenspace measures, including vegetation indices. We examined the associations of total greenspace, private residential gardens, and other greenspace types with the risk of being diagnosed with overall and site-specific ORC.

Association between socioeconomic deprivation and bone health status in the UK biobank cohort participants.

Unlabelled: The effect of deprivation on total bone health status has not been well defined. We examined the relationship between socioeconomic deprivation and poor bone health and falls and we found a significant association. The finding could be beneficial for current public health strategies to minimise disparities in bone health.

Temporal dynamics of drinking water sodium levels in coastal areas, Cyprus 2009-2020.

Around the world, groundwater salinity levels are increasing in coastal areas, as a result of its systematic overexploitation for domestic, agricultural and industrial demand and potentially due to climate change manifestations (such as, sea level rise). We hypothesized that the groundwater quality of many Mediterranean coastal areas is already being perturbed, especially for water salinity, depending on the groundwater distance from the seafront. The objectives of this study were: i) to evaluate the magnitude and temporal variance of drinking water sodium (Na) as a metric of salt intake used for public health purposes using drinking water data in Cyprus; and ii) to examine the degree of Na enrichment in drinking water as defined by the seawater coastline distance of each sampling point.
