    Androstadienone sensitivity is associated with attention to emotions, social interactions, and sexual behavior in older U.S. adults
    (Public Library of Science, 2023-01-13) Kern, David W.; Kaufmann, Gabriel T.; Hummer, Tom A.; Schumm, L. Philip; Wroblewski, Kristen E.; Pinto, Jayant M.; McClintock, Martha K.; Psychiatry, School of Medicine
    Δ 4,16-androstadien-3-one (androstadienone) is a putative human pheromone often linked to sexual attraction in young adults, although specific associations with sexual behavior are not yet established. Androstadienone also serves a broader social-emotional function beyond the sexual domain, specifically tuning the brain to efficiently process emotional information. Whether these effects persist throughout the lifespan into post-reproductive life is unknown. In a laboratory study of older adults, those with greater androstadienone odor sensitivity paid greater attention to subliminal emotional information, specifically, angry faces (p = 0.05), with a similar relationship to happy faces. In contrast, the physical odor n-butanol (a control) did not affect emotional attention (p = 0.49). We then extended this laboratory research and determined whether sensitivity to androstadienone affects the everyday lives of older adults by measuring their social and sexual behavior. In this second study, we surveyed in a nationally representative sample of US older adults living in their homes (National Social Life and Aging Project, 62-90 years; n = 2,086), along with their sensitivity to androstadienone, general olfactory function, health and demographics. Greater sensitivity to androstadienone was associated with richer social lives: having more friends, increased communication with close friends and family, and more participation in organized social events and volunteer activities (all p's ≤ 0.05, generalized linear models, adjusted for age and gender). It was also associated with more recent sexual activity, more frequent sexual thoughts, and viewing sex as an important part of life (all p's ≤ 0.05). General olfactory function did not explain these associations, supporting a specialized function for this pheromone during everyday life, and expanding its role to social life as well as sexual behavior, likely mediated by enhanced attention to emotional information.

    Systemic corticosteroids in coronavirus disease 2019 (COVID‐19)‐related smell dysfunction: an international view
    (Wiley, 2021) Huart, Caroline; Philpott, Carl M.; Altundag, Aytug; Fjaeldstad, Alexander W.; Frasnelli, Johannes; Gane, Simon; Hsieh, Julien W.; Holbrook, Eric H.; Konstantinidis, Iordanis; Landis, Basile N.; Macchi, Alberto; Mueller, Christian A.; Negoias, Simona; Pinto, Jayant M.; Poletti, Sophia C.; Ramakrishnan, Vijay R.; Rombaux, Philippe; Vodicka, Jan; Welge-Lüessen, Antje; Whitcroft, Katherine L.; Hummel, Thomas; Otolaryngology -- Head and Neck Surgery, School of Medicine
    The frequent association between coronavirus disease 2019 (COVID-19) and olfactory dysfunction is creating an unprecedented demand for a treatment of the olfactory loss. Systemic corticosteroids have been considered as a therapeutic option. However, based on current literature, we call for caution using these treatments in early COVID-19-related olfactory dysfunction because: (1) evidence supporting their usefulness is weak; (2) the rate of spontaneous recovery of COVID-19-related olfactory dysfunction is high; and (3) corticosteroids have well-known potential adverse effects. We encourage randomized placebo-controlled trials investigating the efficacy of systemic steroids in this indication and strongly emphasize to initially consider smell training, which is supported by a robust evidence base and has no known side effects.
