In medicine, there is growing evidence that gender differences are important and lead to variations in the pathophysiology and treatment of many diseases with traits that appear to be particularly relevant in influencing the outcomes of many morbid forms. Today, the inclusion of gender in biomedical research, to improve the scientific quality and scientific relevance of knowledge, of technology is an increasingly present element precisely due to the practical implications that derive from it. Gender differences describe the biological variability between women and men, which is, in turn, related to differences in the information contained in sex chromosomes, the specific gene expression of autosomes linked to sex, the different number and quality of sex hormones, and their different effects on systems and organs, without neglecting the fact that each of the sexes has different target organs on which these hormones act. Additionally, both genders undergo metabolic changes throughout their lives, and this is especially true for women who show more dramatic changes due to their role in reproduction. Gender differences are not only the result of our genetic makeup but are also mixed with socio-cultural habits, behaviors, and lifestyles, differences between women and men, exposure to specific environmental influences, different food and lifestyle styles or stress, or different attitude in compliance with treatments and disease prevention campaigns. Gender differences also affect behavior throughout life, and physical changes can have implications for lifestyle, social roles, and mental health. Therefore, determinism and therapeutic outcome in chronic diseases are influenced by a complex combination of biological and environmental factors, not forgetting that there are many interactions of social and biological factors in women and men. This review will address the role of gender differences in the management of various forms of diabetes and its complications considering the different biological functions of hormones, the difference in body composition, physiological differences in glucose and fat metabolism, also considering the role of the microbiota. intestinal, as well as the description of gestational diabetes linked to possible pathophysiological events typical of reproduction.

Coronavirus disease 2019 (Covid-19) is characterized by severe acute respiratory syndrome and is an emerging disease. Considering the changes in maternal physiological and immune function during pregnancy, pregnant women may be at increased risk of being infected with Covid-19 and developing more complicated clinical events. Vertical transmission of the Covid-19 virus is possible although to this day it is still considered a rare event. It is conceivable that most pregnant patients infected with the Covid-19 virus have mild or moderate flu symptoms. More serious symptoms, such as pneumonia, in fact, seem to be more common in the elderly population or in subjects suffering from chronic diseases. As a precaution, pregnant women are considered the most vulnerable and therefore isolation and limitation of contact are recommended. At the moment there are no data to indicate whether spontaneous delivery is preferable in case of coronavirus infection (suspected or confirmed) to a cesarean section. However, in case of breathing difficulties that require delivery as soon as possible, a cesarean section is recommended. There is no evidence that the virus can be transmitted through breast milk. Furthermore, breastfeeding is preferable and has numerous benefits for the newborn's immune system. Since pregnant people appear to have a high risk of becoming seriously ill if they have an infection, vaccination is particularly important. In addition, there is evidence that vaccinated people have a lower risk of baby problems, such as stillbirth.
