    TLDR The document concludes that future heart disease research should account for sex-specific differences to improve diagnosis, treatment, and outcomes.
    The document from June 2, 2020, emphasizes the significance of sex-specific differences in ischemic heart disease (IHD) and cardioprotection research. It points out that sex influences the pathophysiology, incidence, clinical presentation, diagnosis, treatment, and outcomes of IHD. The authors note that risk factors and comorbidities associated with IHD often have different impacts on males and females, which can affect the development and prognosis of the disease. However, most experimental studies on IHD do not consider these differences. The paper recommends that future research should include sex as a biological variable, explore the biological mechanisms behind sex-related differences in IHD risk factors and comorbidities, and use preclinical models that reflect these differences. The document also calls for more research to understand the sex-specific effects of comorbidities and risk factors on IHD, such as hypertension, left ventricular hypertrophy, and various cardiopulmonary and vascular diseases, as well as the role of the immune system and blood diseases like anemia and infections. It suggests that educational programs should raise awareness of sex differences in biology and medicine, and that research should not be limited to common comorbidities but should address a wider spectrum of diseases. The document concludes with recommendations for future research, including the use of both sexes in experimental protocols, clear reporting of experimental details, interdisciplinary approaches, and consideration of sex-specific effects in grant and manuscript reviews.

      Quitting vaping significantly reduced hair loss for a user who was a heavy vaper and also taking finasteride. Some participants suggest nicotine's vasoconstrictive properties may worsen hair loss, while others share personal anecdotes of hair improvement after quitting smoking or vaping.

      Hair loss may be caused by calcification of capillaries in the scalp, restricting blood flow to hair follicles. A daily treatment regimen including high doses of Vitamins D and K, Magnesium, and Nattokinase could potentially decalcify these capillaries, improving blood flow and hair growth. However, some users warn against excessive Vitamin D intake and emphasize the need for medical consultation.
