RESEARCH QUESTION Does placing an intrauterine balloon for different durations (7, 14 or 28 days) affect the recurrence of intrauterine adhesions after hysteroscopic adhesiolysis? DESIGN Prospective randomized control trial involving 138 patients recruited over a 12-month period and followed up post-operatively for 15 months. The primary outcome measure was the rate of adhesion reformation at third-look hysteroscopy. RESULTS At third-look hysteroscopy, 8 weeks after the initial hysteroscopy, the adhesion recurrence rate in women who had an intrauterine balloon for 28 days (20%) was significantly (P  less then  0.01) lower than that of women who had the balloon for 14 days (55%) or 7 days (36.8%). CONCLUSIONS Placing an intrauterine balloon for 28 days instead of 7 or 14 days after hysteroscopic adhesiolysis resulted in a greater reduction in the recurrence rate of adhesions. However, the study was underpowered to address whether the ongoing pregnancy rate could be improved by keeping the balloon in the uterine cavity for a longer period of time. RESEARCH QUESTION Maximizing the number of oocytes and embryos obtained in the shortest possible time is of considerable potential clinical significance for women with poor prognosis.  https://www.selleckchem.com/products/aminoguanidine-hydrochloride.html  The aim of this study was to develop a clinically applicable strategy to obtain more oocytes and viable embryos in one menstrual cycle for poor-prognosis women. DESIGN Prospective cohort study of 146 women with poor prognosis who received rescue in-vitro maturation (IVM) (n = 50) or double ovarian stimulation (DuoStim) (n = 96) between December 2015 and February 2018. Outcomes, number of oocytes retrieved and matured, and embryo developmental potential were compared between the two groups. RESULTS The rates of mature oocytes, available embryos and top-quality embryos from luteal phase stimulation (LPS) of DuoStim were all significantly higher than those derived from the immature oocytes of rescue IVM (P less then 0.05). The relative contributions of LPS in the DuoStim group for proportion of mature oocytes, available embryos and top-quality embryos were all significantly higher than IVM in the rescue IVM group (P less then 0.001). The overall cancellation rate of no oocyte or available embryo significantly decreased from 30.21% to 9.38% (P less then 0.001) when DuoStim was carried out, which decreased from 24.00% to 12.00% with no significant difference in the rescue IVM group when immature sibling oocytes were matured in vitro. CONCLUSION Rescue IVM and DuoStim can contribute more competent oocytes and viable embryos in the shortest possible time for poor-prognosis women, of which DuoStim may be more efficient. RESEARCH QUESTION Is ovarian tissue cryopreservation (OTC) for fertility preservation in prepubertal and adolescent girls safe, and who would benefit most from the procedure? DESIGN Survey and retrospective study including patients who had OTC under the age of 18 years in a single centre for fertility preservation. Serum anti-Müllerian hormone levels were measured as a marker for detection of diminished ovarian reserve. RESULTS Fifty-three from 102 women participated in the survey (12 deceased, 19 declined, 17 unreachable, 1 palliative). The average age at OTC was 14.8 ± 2.3 (range 6-17) years and at survey 21.9 ± 4.3 (range 16-33) years. Ovarian tissue retrieval (laparoscopy n = 45, laparotomy n = 8) was without complications in 52 cases. In 23 (53.5%) of the 43 women who were post-menarchal at OTC, transient amenorrhoea occurred. At survey, 15 women reported a regular menstrual cycle, 25 used oral contraceptives, 9 women reported hormone replacement therapy due to primary ovary insufficiency and 4 had amenorrhoea. Two patients reported the birth of a healthy child after IVF, while 51 patients are still childless, mostly due to their young age (mean 21.2 years). To date, one patient has had transplantation of the ovarian tissue (17 years at cryopreservation). Forty-nine of the interviewees would again decide on OTC, while three argued against it on the basis of the previous financial cost; one woman was unsure. CONCLUSIONS Children with cancer may be at risk for gonadal insufficiency. OTC is practically the only technique that can be offered to young girls. The procedure is safe and well accepted. OBJECTIVE To assess agreement between oscillometric noninvasive blood pressure (NIBP) measurements using LifeWindow monitors (LW9xVet and LW6000V) and invasive blood pressure (IBP). To assess the agreement of NIBP readings using a ratio of cuff width to mid-cannon circumference of 25% and 40%. STUDY DESIGN Prospective, randomized clinical study. ANIMALS A total of 43 adult horses undergoing general anesthesia in dorsal recumbency for different procedures. METHODS Anesthetic protocols varied according to clinician preference. IBP measurement was achieved after cannulation of the facial artery and connection to an appropriately positioned transducer connected to one of two LifeWindow multiparameter monitors (models LW6000V and LW9xVet). Accuracy of monitors was checked daily using a mercury manometer. For each horse, NIBP was measured with two cuff widths (corresponding to 25% or 40% of mid-cannon bone circumference), both connected to the same monitor, and six paired IBP/NIBP readings were recorded (at least 3 minutes between readings). NIBP values were corrected to the relative level of the xiphoid process. A Bland-Altman analysis for repeated measures was used to assess bias (NIBP-IBP) and limits of agreement (LOAs). RESULTS The 40% cuff width systolic arterial pressure [SAP; bias 7.9 mmHg, LOA -26.6 to 42.3; mean arterial pressure (MAP) bias 4.9 mmHg, LOA -28.2 to 38.0; diastolic arterial pressure (DAP) bias 4.2 mmHg, LOA -31.4 to 39.7)] performed better than the 25% cuff width (SAP bias 26.4 mmHg, LOA -21.0 to 73.9; MAP bias 15.7 mmHg, LOA -23.8 to 55.2; DAP bias 10.9 mmHg, LOA -33.2 to 54.9). CONCLUSIONS AND CLINICAL RELEVANCE Using the LifeWindow multiparameter monitor in anesthetized horses, the 40% cuff width provided better agreement with IBP; however, both cuff sizes and both monitor models failed to meet American College of Veterinary Internal Medicine Consensus Statement Guidelines.
