OBJECTIVE To assess the first year's use with the GyneFix intra-uterine device. This has been used in Liverpool since early 1997. It is offered mainly to nulliparous women wishing to use an effective non-hormonal method and parous women who have had pain with, or expulsion of, a framed device previously. It is also used as emergency contraception. DESIGN Retrospective study, by means of casen...

Prolonged or frequent secretion of adrenal glucocorticoids in response to aversive stimuli can negatively impact reproduction. Because female southern white rhinoceros (Ceratotherium simum simum) reproduce poorly in captivity, we compared fecal corticosterone metabolite concentrations among parous, nulliparous, and adolescent females and examined social and physical aspects of the captive envir...

OBJECTIVE To compare the route of delivery among nulliparous parturients with and without an engaged vertex in the early, active phase of labor. METHODS Prospectively, the position of the fetal head was ascertained among nulliparous women at 37 weeks' gestation or more in early, active labor (cervical dilation > or = 4 cm with adequate contractions). Sixteen variables, including maternal demo...

The epidemiology and bacteriology of urinary tract infection (UTI) varies across the human lifespan, but the reasons for these differences are poorly understood. Using established monomicrobial and polymicrobial murine UTI models caused by uropathogenic Escherichia coli (UPEC) and/or Group B Streptococcus (GBS), we demonstrate age and parity as inter-related factors contributing to UTI suscepti...

OBJECTIVE To describe the incidence and clinical and epidemiological profile of patients with severe preeclampsia admitted to Intensive Care. DESIGN A prospective, observational case series. SETTING A specific obstetric 8-bed ICU belonging to a university hospital with a total of 55 ICU beds. PATIENTS A total of 262 patients admitted due to severe preeclampsia, eclampsia or HELLP syndrome...

The objective of this study was to compare the efficacy of diff erent estrus synchronization protocols on reproductive parameters in nulliparous Saanen goats at the end of the transition period. In this experiment, 71 nulliparous Saanen does were used and divided into four treatment groups as norgestomet implant plus GnRH (Imp-G), norgestomet implant (Imp), FGA sponge plus GnRH (Spo-G), and FGA...

BACKGROUND Mode of delivery at first childbirth largely determines mode of delivery at subsequent births, so it is particularly important to understand risk factors for cesarean delivery at first childbirth. In this study, we investigated risk factors for cesarean delivery among nulliparous women, with focus on the association between labor induction and cesarean delivery. METHODS A prospecti...

OBJECTIVE To evaluate the effects of aging, independent of parity, on pelvic organ and urethral support, urethral function, and levator function in a sample of nulliparous women. METHODS A cohort of 82 nulliparous women, aged 21-70 years, were recruited from the community through advertisements. Subjects underwent pelvic examination using pelvic organ prolapse quantification, urethral angles ...
