Extended-release venlafaxine, 75 mg per day, is an effective treatment for postmenopausal hot flushes in otherwise healthy women, based on a significant decrease in patient-perceived hot flush score.

Current protocols for fetal surgery require cesarean section and partial fetal extraction, both of which impart significant risks to the mother and fetus. Endoscopic fetal surgery is less invasive and will likely reduce some of these risks, but the technical difficulties and feasibility in a primate model have yet to be explored fully. Four pregnant baboons (95 days gestation) were anesthetized, their uteruses exposed via an abdominal incision, and blunt-tipped flanged endoscopic ports inserted. Amniotic fluid was removed, and warmed saline was infused to dilate the uterus. To evaluate instrumentation and wound closure, the tip of the snout was externalized and bilateral cleft lip-like defects made. The lips were then endoscopically repaired by suture (Endostitch, U.S. Surgical) or unique nonpenetrating clips (VCS, U.S. Surgical). The saline was then removed, amniotic fluid returned, and the ports carefully removed. After 4 weeks, the fetuses were delivered and evaluated. Eight cleft lip-like defects were successfully repaired in all four cases. Operative time averaged 83 min. No infections, amniotic leaks, or adhesions developed. Survival was 50% with two fetuses delivering within 48 hours postoperatively: one from preterm labor, the other with fetal demise from retroperitoneal hemorrhage after operative blunt abdominal trauma. We demonstrate the feasibility of endoscopic fetal surgery in primates. The use of blunt-tipped flanged ports provides a fluid tight seal and allows appropriate closure of the fetal membranes, but requires laparotomy and uterine exposure. Distension of the uterus with warmed saline affords a larger operating field, enhancing visualization and instrumentation of the fetus. Grasping the fetus through the exposed uterus gives excellent control for repair. However, such control is also needed in a percutaneous approach. Further instrumentation development is needed to accomplish similar control for the percutaneous approach.

We report the new finding that regularly menstruating older women not only have lower pregnanediol-3-glucuronide levels but also have a significant reduction in luteal phase estrone-3-glucuronide compared with a contemporaneous cohort of younger women. This combined deficit may play a key role during the luteal-follicular transition, potentially affecting follicle recruitment and decreasing fecundity in the subsequent cycle.

This analysis supports a hot flash RCT duration of at least 8 weeks to reasonably assess a nonhormonal compound's long-term efficacy.

We compared the difference between a nonpenetrating silver microclip and suture on wound healing, inflammatory response, and application time in the repair of surgically created standardized unilateral cleft lip type defects in fetal mice. Excellent lip continuity and dermal reconstitution were achieved by both methods of repair. Furthermore, collagen accumulation did not occur. Occasional mononuclear cells were seen around sutured repairs in contrast to microclipped repairs. The most significant difference, however, was in application time with the microclip requiring an average of 7 seconds (+/- 2) compared to 90 seconds (+/- 15) for suture. We conclude that the microclip offers distinct advantages for intrauterine cleft lip repair: (1) nonpenetrating tissue approximation; (2) less inflammatory response than suture; (3) technically more rapid and less difficult to apply than suture; and (4) can be utilized more readily than suture for endoscopic approaches limiting the risks of fetal surgery for both the mother and the fetus.
