(p. 326-327) Which of the following is NOT one of the major controllable risk factors known to increase the likelihood of cardiovascular disease?

Ancient bacteria of the tzis microbiome: a genomic tale from the Copper Age.

A longer duration of illness and treatment, often in hospitals, increases health care costs as well as the economic burden on families and societies.

Finally, we identify some principles that could guide strategies to reduce risks, with particular focus on challenges in low- and middle-income countries (Box1) and emissions from antibiotic manufacturing. Antibiotics and antifungals save lives, but their use can encourage the emergence of bacterial strains that are resistant to them. This is because of, for example, limited surveillance and diagnostic opportunities, less-controlled use of antibiotics in both humans and animals, overcrowding in hospitals, insufficient hygiene control, often rapidly growing meat and fish production, an overall greater infection burden, and limited access to expensive, second-line or third-line antibiotics167. 72, 26902703 (2017). 58.

Exposure to surface waters heavily contaminated by faecal residues can also lead to various infections97. This strong over-representation is coherent with the hypothesis that human and/or domestic animals provide the most important environments for resistance evolution under a selection pressure from antibiotics. This has led, for example, to the bathing water directive in the European Union, which uses the levels of faecal indicator bacteria as surrogate exposure thresholds. Quickly and professionally.
