Reducing spontaneous preterm birth
Reduction in activity by the mother—pelvic rest, limited work, bed rest—may be recommended although there is no evidence it is useful with some concerns it is harmful. Increasing medical care by more frequent visits and more education has not been shown to reduce preterm birth rates. Use of nutritional supplements such as omega-3 polyunsaturated fatty acids is based on the observation that populations who have a high intake of such agents are at low risk for preterm birth, presumably as these agents inhibit production of proinflammatory cytokines. A randomized trial showed a significant decline in preterm birth rates, and further studies are in the making. Antibiotics
While antibiotics can get rid of bacterial vaginosis in pregnancy, this does not appear to change the risk of preterm birth. It has been suggested that chronic chorioamnionitis is not sufficiently treated by antibiotics alone (and therefore they cannot ameliorate the need for preterm delivery in this condition). Progestogens
Progestogens—often given in the form of vaginal progesterone or hydroxyprogesterone caproate—relax the uterine musculature, maintain cervical length, and possess anti-inflammatory properties; all of which invoke physiological and anatomical changes considered to be beneficial in reducing preterm birth. Two meta-analyses demonstrated a reduction in the risk of preterm birth in women with recurrent preterm birth by 40–55%.Progestogen supplementation also reduces the frequency of preterm birth in pregnancies where there is a short cervix. A short cervix is one that is less than 25mm, as detected during a transvaginal cervical length assessment in the midtrimester.
Pederasty or paederasty (US:  or UK: ) is a sexual relationship between an adult man and a pubescent or adolescent boy. The term pederasty is primarily used to refer to historical practices of certain cultures, particularly ancient Greece and ancient Rome. In most countries today such relationships are illegal. The local age of consent determines whether a person is considered legally competent to consent to sexual acts, and whether such contact is child sexual abuse or statutory rape. An adult engaging in sexual activity with a minor may be considered abusive by medical authorities for a variety of reasons, including the age of the minor, the likelihood of the minor developing one or more mental disorders, such as post-traumatic stress disorder, physical injury to the minor, and the minors propensity for further victimization in adulthood. Etymology and usage
Pederasty derives from the combination of Ancient Greek: παίδ-, romanized: paid-, lit. boy, child (stem) with ἐραστής, erastēs, lover (cf. eros). Late Latin pæderasta was borrowed in the 16th century directly from Platos classical Greek in The Symposium. (Latin transliterates αί as æ.) The word first appeared in the English language during the Renaissance, as pæderastie (e.g. in Samuel Purchas Pilgrimes), in the sense of sexual relations between men and boys. The Oxford English Dictionary defines it as "Homosexual relations between a man and a boy; homosexual anal intercourse, usually with a boy or younger man as the passive partner".
