OBJECTIVE The aim of this study was to investigate the impact of pretreatment with transdermal estradiol (E2) compared to oral contraceptive pills (OCPs) on controlled ovarian stimulation (COS) response in normal responders undergoing fresh in vitro fertilization (IVF)-embryo transfer (ET) cycles. METHODS A retrospective cohort study was performed of normal responders undergoing fresh IVF-ET ...

Sediments were sampled from different surface water bodies in Tianjin coastal area, China, and persistent organic pollutants (POPs) including polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) were measured using GC/MS or GC/ECD. The purposes were to investigate the concentration levels of the P...

Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were measured by a gas chromatography-mass spectometry (GC-MS) in some edible fish from Huairou Reservoir and Gaobeidian Lake in Beijing, China. The concentrations of OCPs and PCBs were higher in fish (except Misgurnus anguillicaudatus) from Gaobeidian Lake than in those from Huairou Reservoir. The average concentrations of H...

Evidence There are no long-term RCTs, which leaves cohort and case-control studies as evidence. • The Society of Obstetricians and Gynaecologists of Canada1 and others2 have stated that evidence about the risk of VTE with different progestins is inconclusive owing to mixed results and a high risk of bias. • Some studies found no increased VTE risk with drospirenone3 or a transdermal patch.4 • S...

OBJECTIVE To compare the effectiveness of nonsurgical abnormal uterine bleeding treatments for bleeding control, quality of life (QOL), pain, sexual health, patient satisfaction, additional treatments needed, and adverse events. DATA SOURCES MEDLINE, Cochrane databases, and Clinicaltrials.gov were searched from inception to May 2012. We included randomized controlled trials of nonsurgical tre...

In the Chinese city of Wuchang, Heilongjiang Province, a survey was conducted to track concentrations and distributions several organic pollutants near drinking water reservoirs, such as conventional organochlorine pesticides (OCPs) currently in use (CUPs), including organophosphorus (OPPs) neutral herbicides (NHs). From October 2007 July 2008, total 32 pairs sediment samples were gathered exam...

OBJECTIVE To systematically review epidemiologic evidence assessing whether hormonal contraception alters the risk of HIV transmission from an HIV-positive woman to an HIV-negative male partner. DESIGN Systematic review. METHODS We included articles published or in press through December 15, 2011. We assessed studies with direct evidence on hormonal contraception use and HIV transmission, a...

BACKGROUND Oral contraceptive pills (OCPs) are one of the most reliable methods of contraception. However, lack of knowledge about oral contraceptive use and inconsistent pill-taking might result in decreased efficacy. The study reported here aimed to explore women's knowledge about oral contraceptive use and assess the factors associated with knowledge about OCPs among users. METHODS This cr...
