Indications and Efficacy of Progestogen‐Monotherapy as Menopause Hormone Therapy: A Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Menopausal hormone therapy (MHT) remains the most effective treatment for vasomotor symptoms (VMS) and other manifestations of menopause; however, its use is limited in women with contraindications to oestrogen. Progestogen monotherapy, though historically underutilized, represents a viable alternative in this population. This narrative review

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.
