Perceptions of a night float system of resident call within an obstetrics and gynaecology residency training program.
To determine the attitudes of residents, attending obstetricians, and nursing staff members towards night float resident call, compared with a traditional 24-hour call system. ⋯ Resident attitudes towards night float call are mostly positive. Attitudes of attending obstetricians are mixed, but nurses prefer this system of resident call.

Comparative Study Clinical TrialPost-uterine artery embolization pain and clinical outcomes for symptomatic myomas using gelfoam pledgets alone versus embospheres plus gelfoam pledgets: a comparative pilot study.
To evaluate the efficacy and post-procedural pain associated with uterine artery embolization (UAE) using Gelfoam alone versus Embospheres plus Gelfoam in women with symptomatic uterine fibroids. ⋯ Clinical outcomes were equivalent after uterine artery embolization using Gelfoam alone versus Gelfoam + Embospheres. Although the amount of immediate post-procedure pain may be less with Gelfoam alone, we could not demonstrate this objectively using morphine use as a measure of pain.

To review the clinical aspects of ovarian hyperstimulation syndrome and provide recommendations on its prevention. ⋯ The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). Summary Statements 1. The particular follicle-stimulating hormone formulation used for ovarian stimulation does not affect the incidence of ovarian hyperstimulation syndrome. (I) 2. Coasting may reduce the incidence of severe ovarian hyperstimulation syndrome. (III) 3. Coasting for longer than 3 days reduces in vitro fertilization pregnancy rates. (II-2) 4. The use of either luteinizing hormone or human chorionic gonadotropin for final oocyte maturation does not influence the incidence of ovarian hyperstimulation syndrome. (I) 5. There is no clear published evidence that lowering the human chorionic gonadotropin dose will result in a decrease in the rate of ovarian hyperstimulation syndrome. (III) 6. Cabergoline starting from the day of human chorionic gonadotropin reduces the incidence of ovarian hyperstimulation syndrome in patients at higher risk and does not appear to lower in vitro fertilization pregnancy rates. (II-2) 7. Avoiding pregnancy by freezing all embryos will prevent severe prolonged ovarian hyperstimulation syndrome in patients at high risk. (II-2) 8. Pregnancy rates are not affected when using gonadotropin-releasing hormone (GnRH) agonists in GnRH antagonist protocols for final egg maturation when embryos are frozen by vitrification for later transfer. (II-2) Recommendations 1. The addition of metformin should be considered in patients with polycystic ovarian syndrome who are undergoing in vitro fertilization because it may reduce the incidence of ovarian hyperstimulation syndrome. (I-A) 2. Gonadotropin dosing should be carefully individualized, taking into account the patient's age, body mass, antral follicle count, and previous response to gonadotropins. (II-3B) 3. Cycle cancellation before administration of human chorionic gonadatropin is an effective strategy for the prevention of ovarian hyperstimulation syndrome, but the emotional and financial burden it imposes on patients should be considered before the cycle is cancelled. (III-C) 4. Gonadotropin-releasing hormone (GnRH) antagonist stimulation protocols are recommended in patients at high risk for ovarian hyperstimulation syndrome (OHSS). The risk of severe OHSS in patients on GnRH antagonist protocols who have a very robust ovarian stimulation response can be reduced by using a GnRH agonist as a substitute for human chorionic gonadotropin to trigger final oocyte maturation. (I-B) 5. A gonadotropin-releasing hormone (GnRH) antagonist protocol with a GnRH agonist trigger for final oocyte maturation is recommended for donor oocyte and fertility preservation cycles. (III-C) 6. Albumin or other plasma expanders at the time of egg retrieval are not recommended for the prevention of ovarian hyperstimulation syndrome. (I-E) 7. Elective single embryo transfer is recommended in patients at high risk for ovarian hyperstimulation syndrome. (III-C) 8. Progesterone, rather than human chorionic gonadotropin, should be used for luteal phase support. (I-A) 9. Outpatient culdocentesis should be considered for the prevention of disease progression in severe ovarian hyperstimulation syndrome. (II-2B).

Altered hemodynamics and hyperuricemia accompany an elevated sFlt-1/PlGF ratio before the onset of early severe preeclampsia.
Early identification of women at risk of developing early-onset severe preeclampsia (sPE) is a key objective in obstetrics. An elevated ratio of serum soluble fms-like tyrosine kinase (sFlt-1) to placenta-like growth factor (PlGF) (sFlt-1/PlGF ratio) precedes overt hypertension. The longitudinal relationship between this biomarker, maternal hemodynamics, and maternal serum uric acid during the pre-clinical phase is unknown. ⋯ A combination of non-invasive determination of TPR together with measurement of serum uric acid may identify a subset of clinically high-risk women with evolving sPE, independent of the determination of the sFlt-1/PlGF ratio. The predictive ability of this integrated approach needs to be assessed in a larger cohort of women to further confirm its utility.

Meta AnalysisThe effects of ursodeoxycholic acid treatment for intrahepatic cholestasis of pregnancy on maternal and fetal outcomes: a meta-analysis including non-randomized studies.
The benefits of ursodeoxycholic acid (UDCA) use for treating intra-hepatic cholestasis of pregnancy (ICP) remain uncertain. A 2010 Cochrane Review of randomized control trials was unable to recommend either for or against the use of UDCA in treating ICP. We conducted a meta-analysis of the literature, including both non-randomized studies (NRSs) and RCTs. The objective of the study was to determine if patients included in NRSs were comparable to those in RCTs, and to determine whether the inclusion of NRSs could strengthen the available evidence and guide clinical practice on UDCA use in women with ICP. ⋯ UDCA treatment should be recommended for women with ICP to reduce adverse maternal and fetal outcomes.
