    Abstract Women live longer than men. Cardiovascular disorders, cancers, and serious infectious conditions are less common among women than men. Recent data also indicate that women, particularly before menopause, are less susceptible to severe COVID-19, a viral infection hitting less-healthy individuals. The superiority of women regarding health has not been completely understood and partly been explained by estradiol beneficial effects on the microenvironment of the body, notably cytokine network. Estradiol cycles are aligned with menstruation cycles, a challenge for distinguishing their individual effects on human health. Large-scale, long-term studies indicate that hysterectomy, particularly at younger ages, is associated with an increased risk of mortality, cancer, or heart disorders. The underlying mechanisms for the increased risk in hysterectomized women are hard to be investigated in animal models since only a few primates menstruate. However, blood exchange models could resemble menstruation and provide some insight into possible beneficial effects of menstruation. Sera from animal models (neutral blood exchange) and also humans that have undergone therapeutic plasma exchange enhance the proliferation of progenitor cells in the culture and contain lower levels of proinflammatory factors. If menstruation resembles a blood exchange model, it can contribute to a healthier cytokine network in women. Consequently, menstruation, independently from estradiol health beneficial effects, can contribute to greater longevity and protection against certain disorders, e.g., COVID-19, in women. Investigation of COVID-19 rate/severity in hysterectomized women will provide insight into the possible beneficial effects of menstruation in COVID-19.

    Abstract So far, the COVID-19 pandemic has caused less casualty in Eastern Asia areas compared to the other parts of the world. The pattern of less casualty in the pandemic origin has also been observed in the three main flu pandemics in the last century. It is reasonable to speculate that less casualty of COVID-19/flu in the pandemic origin is likely due to the preexisting cross-immunity to some close viruses being more prevalent in those regions. Experts and modelers should scale up the severity of a flu-like viral epidemic to predict its real severity for the rest of the world.

    Abstract Resistance to a drug and the suppression of inflammatory disorders with immunosuppressive drugs might have happened upon exposure to natural compounds during evolution. Streptomycetes are soil bacteria, but they produce therapeutic drugs. They have been reported to be the low-abundant members of mucosal microbiomes with a higher prevalence in nonhumans ingesting soil compared with humans. Their lower abundance in the human microbiome might be the representations of our current hygienic lifestyle. We suggest that the Streptomyces bacteria producing antiproliferative/immunosuppressive compounds (e.g., rapamycin and tacrolimus) contribute to the rapalog resistance of certain mucosal tumours (e.g., colon cancer) and the 'hygiene hypothesis'. If so, the shortage of exposure to these compounds in the current lifestyle might be an underlying reason for the increase of inflammatory diseases, such as inflammatory bowel diseases (IBD). An investigation on adding certain Streptomycetes (e.g., S. hygroscopicus and S. tubercidicus) to the list of probiotics against inflammatory diseases would be an interesting research area in the future.

    Abstract Inflammation contributes to colon cancer initiation. The disease along with allergy and autoimmunity has been on the rise in Western and more recently in developing countries. This shared rise may imply a shared cause. Streptomycetes are known as soil residents and produce numerous antiproliferative, anti-inflammatory/immunosuppressive compounds, e.g. rapamycin and tacrolimus. Recently, Streptomyces has been shown in gut microbiome with a lower prevalence in humans than nonhumans whose microbiomes might be more representative of past humans' in a hunter-gatherer and farming environment. It was previously suggested that Streptomyces producing antiproliferatives/immunosuppressants would be 'old friends' against allergy and autoimmunity as well as inflammatory bowel diseases. Here, it is suggested that these streptomycetes within gut microbiome have also been evolved as 'old friends' to suppress colon tumorigenesis through their numerous antiproliferatives/immunosuppressants. Subsequently, the shortage of exposure to nature in our current lifestyle has cost us the shortage of these friends and vulnerability to colon cancer. An attractive research area in the future would be whether the shortage of Streptomyces exposure can be the underlying reason for colon cancer, allergy and autoimmunity rise, and if the restoration of these 'old friends' through probiotics or more exposure to nature can prevent colon cancer.
