Abstract:
This study assesses the baseline knowledge of emergency contraception (EC) in a Boston neighborhood. A written survey was distributed to women aged 18-44 years in the Boston neighborhood of Jamaica Plain. Of the 188 participants, 82% have heard of EC. Knowledge disparities by race/ethnicity groups were seen, with only 51% of Latina women and 75% of Black women having heard of EC compared with 99% of White women (p < .0001 and p = .002, respectively). Of the entire cohort, 39% knew that EC works by preventing pregnancy, 48% knew that it should be taken within 72-120 h of unprotected intercourse and 44% knew that it is only available by prescription in Massachusetts. Only 25% of women have ever discussed EC with a health care provider, and only 12% have ever received an advance prescription. A community education campaign aimed at reproductive-age women, health care providers and pharmacists has been tailored to address these knowledge deficits.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
