- Alterations in metabolism influence lifespan in experimental models, but data in humans are lacking. Here we use liquid chromatography/mass spectrometry to quantify 217 plasma metabolites and examine their relation to longevity in a large cohort of men and women followed for up to 20 years. We find that, higher concentrations of the citric acid cycle intermediate, isocitrate, and the bile acid, taurocholate, are associated with lower odds of longevity, defined as attaining 80 years of age. Higher concentrations of isocitrate, but not taurocholate, are also associated with worse cardiovascular health at baseline, as well as risk of future cardiovascular disease and death. None of the metabolites identified are associated with cancer risk. Our findings suggest that some, but not all, metabolic pathways related to human longevity are linked to the risk of common causes of death.

Sustainability challenges throughout the electric vehicle battery value chain
- 2024

Research review (peer-reviewed)abstract
- The global commitment to decarbonizing the transport sector has resulted in an unabated growth in the markets for electric vehicles and their batteries. Consequently, the demand for battery raw materials is continuously growing. As an illustration, to meet the net-zero emissions targets, the electric vehicle market demand for lithium, cobalt, nickel, and graphite will increase 26-times, 6-times, 12-times, and 9-times respectively between 2021 and 2050. There are diverse challenges in meeting this demand, requiring the world to embrace technological and knowledge advancements and new investments without provoking conflicts between competing goals. The uncertainties in a sustainable supply of battery minerals, environmental, social and governance complexities, and geopolitical tensions throughout the whole battery value chain have shaped the global and regional concerns over the success of transport decarbonization. Here, focusing on the entire value chain of electric vehicle batteries, the approaches adopted by regulatory agencies, governments, mining companies, vehicle and battery manufacturers, and all the other stakeholders are evaluated. Bringing together all these aspects, this literature review broadens the scope for providing multifaceted solutions necessary to optimize the goal of transport decarbonization while upholding sustainability criteria. Consolidating the previously fragmented information, a solid foundation for more in-depth research on existing difficulties encountered by governmental and industrial actors is created. The outcomes of this study may serve as a baseline to develop a framework for a climate smart and resource efficient supply of batteries considering the unique impacts of individual players.

Multidrug-resistant pathogens contaminate river water used in irrigation in disenfranchised communities
- 2024
-
In: Journal of Global Antimicrobial Resistance. - : Elsevier. - 2213-7165 .- 2213-7173. ; 36, s. 175-180

Journal article (peer-reviewed)abstract
- Objectives: The contamination of fresh surface waters poses a significant burden on human health and prosperity, especially in marginalized communities with limited resources and inadequate infrastructure. Here, we performed in-depth genomic analyses of multidrug-resistant bacteria (MDR-B) isolated from Al-Oueik river water that is used for irrigation of agricultural fields in a disenfranchised area that also hosts a makeshift Syrian refugee camp.Methods: A composite freshwater sample was filtered. Faecal coliforms were counted and extended spectrum cephalosporins and/or ertapenem resistant bacteria were screened. Isolates were identified using MALDI-TOF-MS and analysed using whole-genome sequencing (WGS) to identify the resistome, sequence types, plasmid types, and virulence genes.Results: Approximately 106 CFU/100 mL of faecal coliforms were detected in the water. Four drug-resistant Gram-negative bacteria were identified, namely Escherichia coli, Klebsiella pneumoniae, Enterobacter hormaechei, and Pseudomonas otitidis. Notably, the E. coli isolate harboured blaNDM-5 and a YRIN-inserted PBP3, representing an emerging public health challenge. The K. pneumoniae isolate carried blaSHV-187 as well as mutations in the gene encoding the OmpK37 porin. Enterobacter hormaechei and P. otitidis harboured blaACT-16 and blaPOM-1, respectively.Conclusion: This report provides comprehensive genomic analyses of MDR-B in irrigation water in Lebanon. Our results further support that irrigation water contaminated with faecal material can be a reservoir of important MDR-B, which can spread to adjacent agricultural fields and other water bodies, posing both public health and food safety issues. Therefore, there is an urgent need to implement effective water quality monitoring and management programs to control the proliferation of antibiotic-resistant pathogens in irrigation water in Lebanon.

Tackling Ethnic Health Disparities Through Community Health Worker Programs : A Scoping Review on Their Utilization During the COVID-19 Outbreak
- 2022

In: Population health management. - : Mary Ann Liebert. - 1942-7891 .- 1942-7905. ; 25:4, s. 517-526

Research review (peer-reviewed)abstract
- The coronavirus disease (COVID-19) outbreak has magnified existing health inequities linked to social determinants of health, with racial and ethnic minorities being disproportionately affected by the pandemic. A proposed strategy to address these inequities is based on the implementation of community health worker (CHW) programs able to bridge the gaps between marginalized communities and the formal health care systems. A scoping review was conducted through searching 4 databases: PubMed, Scopus, Web of Science, and Science Direct. Inclusion criteria focused on studies defining any kind of adopted CHW intervention to address inequities related to racial/ethnic groups during the COVID-19 crisis, published from December 31, 2019, to October 31, 2021. Narrative synthesis was undertaken to summarize the findings. In total, 23 studies met the inclusion out of the 107 search results. Data converged on the relevant potential of CHWs on engaging with community leaders, addressing social determinants of health, and issues related to structural racism, promoting culturally tailored health information, and encouraging institutions to policy change in favor of people left behind. Although vulnerability of racial and ethnic minorities was already present before the COVID-19 outbreak, the pandemic has represented a wakeup call to address it more efficiently. In recent years, CHWs have increasingly been acknowledged as valuable members of the health care workforce. As health disparities may increase after our multicultural societies begin to recover from COVID-19, CHWs may play a crucial role in addressing system-level changes to have broad and lasting effects on health outcomes.

2-Aminoadipic acid is a biomarker for diabetes risk
- 2013

Journal article (peer-reviewed)abstract
- Improvements in metabolite-profiling techniques are providing increased breadth of coverage of the human metabolome and may highlight biomarkers and pathways in common diseases such as diabetes. Using a metabolomics platform that analyzes intermediary organic acids, purines, pyrimidines, and other compounds, we performed a nested case-control study of 188 individuals who developed diabetes and 188 propensity-matched controls from 2,422 normoglycemic participants followed for 12 years in the Framingham Heart Study. The metabolite 2-aminoadipic acid (2-AAA) was most strongly associated with the risk of developing diabetes. Individuals with 2-AAA concentrations in the top quartile had greater than a 4-fold risk of developing diabetes. Levels of 2-AAA were not well correlated with other metabolite biomarkers of diabetes, such as branched chain amino acids and aromatic amino acids, suggesting they report on a distinct pathophysiological pathway. In experimental studies, administration of 2-AAA lowered fasting plasma glucose levels in mice fed both standard chow and high-fat diets. Further, 2-AAA treatment enhanced insulin secretion from a pancreatic beta cell line as well as murine and human islets. These data highlight a metabolite not previously associated with diabetes risk that is increased up to 12 years before the onset of overt disease. Our findings suggest that 2-AAA is a marker of diabetes risk and a potential modulator of glucose homeostasis in humans.
