U-shaped or J-shaped relationships have been demonstrated between BMI and all-cause or cardiovascular mortality. Now, a study has demonstrated the correlation of increased waist circumference, high adipose tissue mass and low adipose tissue-free mass with all-cause and cardiovascular mortality in an Asian population.
Metabolic diseases emerged as important risk factors for severe COVID-19, but the mechanisms responsible remained unclear for some time. The severity of metabolic diseases was also associated with worse outcomes in patients with COVID-19, forcing clinicians to adjust their thinking on which patients with metabolic disease, but without COVID-19, to prioritize for treatment during and immediately after the pandemic.
The development and application of effective immunotherapies for type 1 diabetes mellitus has lagged behind our ability to identify and stage individuals in pre-clinical stages of disease. This Year in Review addresses advances in immunotherapy aimed towards prevention and our readiness to roll out screening in the broader population.
Heart failure and chronic kidney disease are frequent causes of morbidity and mortality in people with type 2 diabetes mellitus. Cardiovascular outcome trials have confirmed benefits of sodium–glucose co-transporter 2 inhibitors on cardiovascular events, cardiovascular deaths, hospitalization for heart failure and renal outcomes. These benefits now extend to people with and without type 2 diabetes mellitus.
Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder characterized by reproductive and metabolic disturbances. Androgen excess is a hallmark of PCOS, driving many of the phenotypic features. In 2020, several findings highlight altered metabolic pathways as an underlying biological mechanism in PCOS. These findings add to our understanding of the complex interaction between metabolic homeostasis and reproduction.
Owing to the strong association of non-alcoholic fatty liver disease with obesity and cardiometabolic disease, in 2020 experts controversially proposed to rename this condition as ‘metabolic associated fatty liver disease’. Additional studies have elucidated new genetic and dietary modifiers of this disease. This knowledge is essential to improve diagnosis, risk-stratification and treatment.
Neuroendocrine neoplasms are derived from the diffuse endocrine system and represent a spectrum of tumours with a diverse range of molecular abnormalities, functionality and anatomical locations. Here, some key advances in molecular diagnosis, functional imaging and therapeutic strategies that have been published in 2020 are discussed.
Exposure to environmental pollutants such as endocrine-disrupting chemicals (EDCs) during critical periods of development can have long-term reproductive consequences. This Review discusses the cellular and molecular consequences of perinatal exposure EDCs with a focus on the neuroendocrine control of reproduction.
The bioactive peptides galanin, spexin and kisspeptin have a common ancestral origin. This Review summarizes the available evidence on the role of these peptides in the regulation of metabolism, pancreatic β-cell function, energy homeostasis, mood and behaviour.
This Review summarizes current knowledge on non-classic and less common causes of hypopituitarism, such as traumatic brain injury, genetic causes, use of immune checkpoint inhibitors, autoimmune diseases and inflammatory diseases. Furthermore, emerging evidence that posterior pituitary damage can affect oxytocin secretion is highlighted.
