We demand a seat at the table. The leadership table. The funding table. The NIH study section table. The high impact authorship table. All are places we deserve to be, yet you don’t find many faces like mine in places like these. You certainly don’t find many experiences like mine.
This article discusses trends in human reproductive behaviour and health that are associated with infertility. These changes have occurred over a period of only a couple of generations, so environmental factors are suggested to have a role.
Whether or not there is a form of healthy obesity remains controversial. Contemporary imaging techniques might help answer this question. It is proposed that low levels of visceral adipose tissue and ectopic adipose tissue combined with a preferential accumulation of gluteal and femoral adipose tissue might define a ‘super healthy obesity’ phenotype.
Statins might exert diabetogenic effects, potentially increasing insulin resistance and worsening glucose control. However, patients with diabetes mellitus are at high or very high cardiovascular risk and, thus, statin use is strongly recommended. Adding ezetimibe to statins might be helpful in achieving lipid targets and reducing cardiovascular risk without adversely affecting glucose metabolism.
Metabolites have emerged as central regulators of biological function, but understanding mechanisms of metabolite regulation has proven challenging. In 2021 we have seen discoveries in the field of metabolite signalling motivated by a combination of scientific intuition and the elegant deployment of new technologies.
In 2021, several discoveries shed light on the pathomechanisms of β-cell failure during the initiation and progression of diabetes mellitus, and validated novel molecular targets for intervention. Moreover, the field of stem-cell-derived replacements for β-cells is rapidly advancing. These advances bring us closer to therapies to protect and/or regenerate β-cell mass.
Physical activity stimulates tissue crosstalk and provides powerful protection against cardiometabolic disease. This past year, several studies have expanded our knowledge of the secreted molecules regulated by physical activity, uncovered new circuits of cell and tissue crosstalk and provided fundamental insights into the mechanisms that underlie the cardiometabolic benefits of exercise.
Obesity and impaired metabolic health are important risk factors for severe COVID-19. Novel data indicate that these risk factors might also promote vaccine-breakthrough SARS-CoV-2 infections in fully vaccinated people. Here, these relationships are discussed and post-acute sequelae of COVID-19 that are related to obesity and impaired metabolic health are addressed.
In 2021, clinical trials reported the promising effects of incretins and a new class of dual glucagon-like peptide 1–glucose-dependent insulinotropic peptide receptor agonists in preventing and treating type 2 diabetes mellitus and obesity. These ‘twincretins’ will transform the prevention of obesity and type 2 diabetes mellitus and the care of people with these conditions.
