Incidence And Mortality

Severe acute respiratory syndrome (SARS)-like coronavirus (SARS-CoV-2) is the seventh member of the coronaviruses (CoVs) family that infects humans and causes coronavirus disease 2019 (COVID-19), which is currently a global pandemic. Widespread secretion of cytokines has been shown to occur early in severe cases of the disease and can be an effective factor in the rapid progression of the disease. The storm of cytokines including interleukin (IL)-1β, IL-2, IL-7, IL-6, IL-8, IL-10, IL-17, and gamma interferon (INF-ɣ) has been reported in several organ failures. Systemic inflammation indicates an advanced stage of acute disease, which is characterized by multiple organ failure and elevated key inflammatory markers. The important disturbances in the various body systems such as alveolar damage and pulmonary edema in the lung, increase of liver enzymes in the liver, decrease of microbiota and increase of mesenteric edema in the gastrointestinal system, increase of blood urea nitrogen (BUN), creatinine (Cr) and glomerular filtration rate (GFR) in the kidney, myocardial dysfunction, arrhythmia and cardiac enzymes elevation in the heart, blood brain barrier (BBB) disruption, brain edema and encephalopathy in the brain have been reported. Studies have shown a gender difference between the incidence and mortality of COVID-19. In this review, we investigated the gender difference in the systemic effects of COVID-19 and found that this gender difference exists especially in the respiratory, cardiovascular, liver, gastrointestinal and kidney systems. Due to the worse outcome of COVID in males, the role of female sex hormones in causing these gender differences is noticeable. There can be a systemic and local effect of female sex hormones, especially estrogen and possibly progesterone, on various cells. Among the effects of these hormones is the regulation of localized angiotensin-converting enzyme 2 (ACE2) levels. ACE2 is the route of entry for SARS-CoV-2 virus into the cell. It is hoped that this review would address gender differences for better management of COVID-19 treatment.

Cancer Rates

Lung cancer represents the world’s leading cause of cancer deaths. Sex differences in the incidence and mortality rates for various types of lung cancers have been identified, but the biological and endocrine mechanisms implicated in these disparities have not yet been determined. While some cancers such as lung adenocarcinoma are more commonly found among women than men, others like squamous cell carcinoma display the opposite pattern or show no sex differences. Associations of tobacco product use rates, susceptibility to carcinogens, occupational exposures, and indoor and outdoor air pollution have also been linked to differential rates of lung cancer occurrence and mortality between sexes. While roles for sex hormones in other types of cancers affecting women or men have been identified and described, little is known about the influence of sex hormones in lung cancer. One potential mechanism identified to date is the synergism between estrogen and some tobacco compounds, and oncogene mutations, in inducing the expression of metabolic enzymes, leading to enhanced formation of reactive oxygen species and DNA adducts, and subsequent lung carcinogenesis. In this review, we present the literature available regarding sex differences in cancer rates, associations of male and female sex hormones with lung cancer, the influence of exogenous hormone therapy in women, and potential mechanisms mediated by male and female sex hormone receptors in lung carcinogenesis. The influence of biological sex on lung disease has recently been established, thus new research incorporating this variable will shed light on the mechanisms behind the observed disparities in lung cancer rates, and potentially lead to the development of new therapeutics to treat this devastating disease.

Salt Sensitive Hypertension

Initial studies found that female Dahl salt-sensitive (DS) rats exhibit greater blood pressure (BP) salt sensitivity than female spontaneously hypertensive rats (SHR). On the basis of the central role played by NO in sodium excretion and BP control, we further tested the hypothesis that blunted increases in BP in female SHR will be accompanied by greater increases in renal inner medullary nitric oxide synthase (NOS) activity and expression in response to a high-salt (HS) diet compared with DS rats. Gonad-intact and ovariectomized (OVX) female SHR and DS rats were placed on normal salt (NS; 0.4% salt) or HS (4% salt) diet for 2 wk. OVX did not alter BP in SHR, and HS diet produced a modest increase in BP. OVX significantly increased BP in DS rats on NS; HS further increased BP in all DS rats, although OVX had a greater increase in BP. Renal inner medullary NOS activity, total NOS3 protein, and NOS3 phosphorylated on serine residue 1177 were not altered by salt or OVX in either strain. NOS1 protein expression, however, significantly increased with HS only in SHR, and this corresponded to an increase in urinary nitrate/nitrite excretion. SHR also exhibit greater NOS1 and NOS3 protein expression than DS rats. These data indicate that female sex hormones offer protection against HS-mediated elevations in BP in DS rats but not SHR. We propose that the relative resistance to HS-mediated increases in BP in SHR is related to greater NOS expression and the ability to increase NOS1 protein expression compared with DS rats.
