A Closer Look at a New Low-Dose Copper IUD

This study reports on the three-year data from an ongoing Phase III study evaluating the efficacy, safety, and tolerability of a new low-dose copper intrauterine device (IUD), demonstrating low rates of expulsion and discontinuation and expanding the nonhormonal IUD options available in the United States.

Is Routine Voiding Necessary Following Minimally Invasive Hysterectomy?

This unblinded, randomized clinical trial of patients undergoing minimally invasive benign nonurogynecologic hysterectomy with anticipated same-day discharge demonstrated that eliminating the requirement to void prior to discharge reduced time spent in the post-anesthesia care unit by 27.14 minutes (173.26 mins no void vs. 201.95 mins void; P = 0.002) without increasing the proportion of patients with postoperative urinary retention (3% void vs. 1% no void; P = 3.69).

Endometrial Biopsy: What Leads to an Insufficient Sample?

In this large retrospective cohort study at a single health system, the rate of insufficient endometrial biopsies among 27,456 patients was 12.1%. The largest risk factor for an insufficient sample was postmenopausal status (adjusted odds ratio, 5.27; 95% confidence interval, 4.88-5.70). Among premenopausal women, a history of cesarean delivery (9.6% vs. 7.2%; P < 0.001) and leiomyomas (10.3% vs. 7.2%; P < 0.001) was associated with insufficient samples.

Managing Suspected Preeclampsia Using the sFlt-1/PlGF Ratio

The sFlt-1/PlGF ratio is a clinically valuable tool for ruling out preeclampsia and improving obstetric decision-making, although its effect depends on appropriate use, clinician confidence in negative results, and adherence to validated protocols.
