TFOS DEWS II Sex, Gender, and Hormones Report

TLDR
Overall, sex, gender and hormones play a major role in the regulation of ocular surface and adnexal tissues, and in the difference in DED prevalence between women and men.
Abstract
One of the most compelling features of dry eye disease (DED) is that it occurs more frequently in women than men. In fact, the female sex is a significant risk factor for the development of DED. This sex-related difference in DED prevalence is attributed in large part to the effects of sex steroids (e.g. androgens, estrogens), hypothalamic-pituitary hormones, glucocorticoids, insulin, insulin-like growth factor 1 and thyroid hormones, as well as to the sex chromosome complement, sex-specific autosomal factors and epigenetics (e.g. microRNAs). In addition to sex, gender also appears to be a risk factor for DED. "Gender" and "sex" are words that are often used interchangeably, but they have distinct meanings. "Gender" refers to a person's self-representation as a man or woman, whereas "sex" distinguishes males and females based on their biological characteristics. Both gender and sex affect DED risk, presentation of the disease, immune responses, pain, care-seeking behaviors, service utilization, and myriad other facets of eye health. Overall, sex, gender and hormones play a major role in the regulation of ocular surface and adnexal tissues, and in the difference in DED prevalence between women and men. The purpose of this Subcommittee report is to review and critique the nature of this role, as well as to recommend areas for future research to advance our understanding of the interrelationships between sex, gender, hormones and DED.

TFOS DEWS II pathophysiology report

TL;DR: The TFOS DEWS II Pathophysiology Subcommittee reviewed the mechanisms involved in the initiation and perpetuation of dry eye disease, finding the targeting of the terminal duct in meibomian gland disease and the influence of gaze dynamics and the closed eye state on tear stability and ocular surface inflammation to be important.

The effects of experimenter characteristics on pain reports in women and men.

TL;DR: The observation that pain responsivity is influenced by the professional status of the experimenter might have implications for the study of pain in general and should be addressed in more detail in future experiments.

Combined oral contraceptive pills for treatment of acne

TL;DR: A large number of placebo-controlled trials showed COCs reduced acne lesion counts, severity grades and self-assessed acne compared to placebo, and were more likely to have a clinician assessment of clear or almost clear lesions and participantself-assessment of improved acne lesions.

Gender differences in drug metabolism regulated by growth hormone

TL;DR: The mouse model, in which the sexual differences in drug metabolizing enzyme activities vary by only 40-100%, are also regulated by sex-dependent plasma growth hormone profiles, and may be more representative of the vast majority of outbred species in which only subtle gender differences occur in drug metabolism.

X-chromosome-located microRNAs in immunity: might they explain male/female differences?: the X chromosome-genomic context may affect X-located miRNAs and downstream signaling, thereby contributing to the enhanced immune response of females

TL;DR: It is hypothesize that X chromosome‐associated mechanisms, which affect X‐linked genes and are behind the immunological advantage of females, may also affectX‐linked microRNAs, which have important functions in immunity and cancer.

Prolactin influences autoimmune disease activity in the female B/W mouse.

TL;DR: This is the first report to substantiate an immunomodulatory role for prolactin in B/W mice and identify specific means of intervening clinically with immunosuppressive hormone-modulating therapy in SLE.
