Abstract Background A number of studies have looked at dual triggers with hCG and GnRH agonist (GnRHa) in varying doses, but the question remains: what is the optimal dose of hCG to minimize ovarian hyperstimulation syndrome (OHSS) and still offer adequate pregnancy rates? The purpose of this study was to compare pregnancy and OHSS rates following dual trigger for oocyte maturation with GnRHa and a low-dose hCG versus hCG alone. A secondary objective was the assess pregnancy outcomes in subsequent frozen cycles for the same population. Methods A total of 963 women < 41 years old, with a BMI 18–40 kg/m2 and an AMH > 2 ng/mL who underwent fresh autologous in vitro fertilization (IVF) with GnRH antagonist protocol at a University-based fertility center were included in this retrospective cohort study. Those who received a low dose dual trigger with hCG (1000u) and GnRHa (2 mg) were compared to those who received hCG alone (10,000u hCG/250-500 μg Ovidrel). Differences in implantation rates, pregnancy, live birth, and OHSS were investigated. Results The dual trigger group was younger (mean 33.6 vs 34.1 years), had a higher AMH (6.3 vs 4.9 ng/mL,) more oocytes retrieved (18.1 vs 14.9) and a higher fertilized oocyte rate (80% vs 77%) compared with the hCG only group. Yet, the dual trigger group had a lower probability of clinical pregnancy (gestational sac, 43.4% vs 52.8%) and live birth (33.4% vs 45.8%), all of which were statistically significant. There were 3 cases of OHSS, all in the hCG-only trigger group. In subsequent frozen cycles, pregnancy rates were comparable between the two groups. Conclusions The dual trigger group had a better prognosis based on age and AMH levels and had better stimulation outcomes, but significantly worse pregnancy outcomes, suggesting the low dose hCG (1000u) in the dual trigger may not have provided adequate luteal support, compared to an hCG-only trigger (10,000u hCG/250-500 μg Ovidrel). Interestingly, the pregnancy rates were comparable in subsequent frozen cycles, further supporting the hypothesis that the issue lies in inadequate luteal phase support, rather than embryo quality. Based on these findings, our program has changed the protocol to 1500u of hCG in a dual trigger.

Abstract Background: GnRH-agonist is used to treat adenomyosis, but its efficacy in adenomyosis patients with uterine enlargement undergoing frozen embryo transfer (FET) is unclear. Methods：The retrospective cohort study comprised 112 adenomyosis patients with uterine enlargement undergoing the first FET circle. A long-term GnRH-a pretreatment was administered to 112 patients with uterine enlargement. These patients were divided into two groups according to the therapeutic effect: patients with a normal-size uterus after GnRH-a treatment (GN group) and patients with an enlarged uterus after GnRH-a treatment (GL group). Results：Not all patients can shrink their uterus to a satisfactory level. After receiving GnRH-a pretreatment, the uterus returned to normal size in 77% of patients (GN group), and 23% of patients had a persistently enlarged uterus (GL group). The pregnancy rate, clinical pregnancy rate, ongoing pregnancy rate, and live birth rate were significantly higher in the GN group than in the GL group. Controlling for the confounding factors, normal uterus size (odds ratio [OR] 4.50; P=0.03) and low body mass index (OR 3.13; P=0.03) affected the odds of achieving live birth. The cut-off value selected on the ROC curve of uterus volume after GnRH-a treatment for detecting live birth was 144.7Conclusions：GnRH-a pretreatment was associated with the regression of adenomyosis lesions and improved clinical pregnancy outcomes in the adenomyosis patients with uterine enlargement whose lesion are GnRH-a susceptible on FET cycles. However, about a quarter of patients may not be less responsive to GnRH-a and have poorer pregnancy outcomes, especially in overweight women.

ObjectiveThis study aimed to compare the ultra-long gonadotropin-releasing hormone agonist (GnRH-a) protocol and the long GnRH-a protocol during in vitro fertilization (IVF) or intracytoplasmic sperm (ICSI) treatment on fertility outcomes in women with adenomyosis.Materials and MethodsThis study was a retrospective cohort study. From January 2011 to May 2018, a total of 371 fresh IVF/ICSI cycles were included. Among the cycles included, 237 cycles of 212 women underwent the ultra-long GnRH-a protocol, while 134 cycles of 116 women underwent the long GnRH-a protocol. The rates of implantation, clinical pregnancy per embryo transfer, live birth, and early miscarriage were estimated between the compared protocols.ResultsIn the study, the early miscarriage rate in women undergoing the ultra-long GnRH-a protocol was significantly lower than those undergoing the long GnRH-a protocol (12.0% versus 26.5%, p = 0.045), whereas the differences in the rates of biochemical pregnancy, implantation, clinical pregnancy, and live birth in women between the two groups showed no statistical significance. The pregnancy outcomes were also sub-analyzed according to the adenomyotic region (diffuse and focal). As for diffuse adenomyosis, the rates of clinical pregnancy and live birth in women undergoing the ultra-long GnRH-a protocol were significantly higher than those undergoing the long GnRH-a protocol (55.3% versus 37.9%, p = 0.025; 43.4% versus 25.9%, p = 0.019, respectively). However, pregnancy outcomes showed no difference between the two protocols in women with focal adenomyosis.ConclusionsThe ultra-long GnRH-a protocol during IVF/ICSI improves pregnancy outcomes in women with adenomyosis, especially in women with diffuse adenomyosis when compared with the long GnRH-a protocol.

Abstract Background: Blood urea nitrogen (BUN) and creatinine (SCr) are associated with gestational diabetes mellitus (GDM). However, there were limited data in the literature on the influence of BUN and SCr on maternal and fetal outcomes of pregnancy. We aimed to examine the association of BUN and SCr levels during gestation with the risk of selected adverse pregnancy outcomes.Methods: This retrospective cohort study included 1606 singleton mothers aged 22-44 years. Both BUN and SCr levels were collected and measured during the second (16-18th week), third (28-30th week) trimesters of gestation respectively and followed up pregnancy outcomes. Statistical analysis was used multivariate logistic regression. Results: In the multivariate adjusted logistic regression model, the highest level of SCr in the second trimester increased the risk of PROM by 45% (95% CI, 1.01-2.09). In the third trimester of gestation, compared with those in the lowest quartile, BUN levels in the highest quartile decreased the risk of macrosomia and LGA by 60%(95% CI, 0.20-0.78), 66%(95% CI, 0.21,0.55) , respectively, and increased the risk of SGA by 137%(1.06, 5.31), 186%(1.29,6.34) in the third and fourth quartiles, respectively. The adjusted OR (95%CI) for macrosomia in the fourth quartile was 0.46 (0.24, 0.87), for SGA in the third quartiles was 2.36 (1.10, 5.10), and for LGA in the fourth quartile was 0.61 (0.41,0.91) compared with those in the first quartile of SCr levels. The elevated changes of BUN (> 0.64mmol/L) was the risk factor of SGA (OR: 2.11, 95%CI: 1.03,4.32).Conclusion: Higher BUN and SCr levels during the 28-30th week of gestation even those towards the upper limit of the normal range can act as a warning sign of the impending SGA. Elevated changes of BUN and SCr during pregnancy also associated with the lower birth weight.

Background: Many guidelines have been issued regarding the number of embryos to be transferred after in vitro fertilization (IVF), but patients and clinicians may be reluctant to accept or offer a single embryo transfer due to the expected lower chance of pregnancy or live birth. This study was aimed to provide additional information on cycle outcome according to the number and quality of thawed transferred blastocysts. Methods:A retrospective cohort study was designed to collect the data of 505 patients who performed the first frozen blastocysts transfer at Tam Anh General Hospital from June 2018 to September 2019. One good-quality embryo was transferred for 121 patients (Group 1), two good for 214 patients (Group 2), one good and one poor for 112 patients (Group 3), one good and two poor for 25 patients (Group 4), and one or two poor for 33 patients (Group 5). Results:The pregnancy rate was 71.9%, 74.8%, 69.4%, 84.0%, and 39.4% in Group 1–5, respectively. The multiple pregnancy rate was 36.9%, 16.9%, and 32.0% in Groups 2–4, respectively, higher than Group 1 (4.9%). The live birth rate was 55.6%, 50.9%, and 60.0% in Group 2–4, respectively, but not significantly different from the Group 1 (47.9%). Conclusions:Transferring an additional good or poor embryo, along with a good embryo, does not increase the live birth rate while the incidence of multiple pregnancies rises significantly.

Incidence Of Dementia

Abstract BACKGROUND Stroke has been recognized as one of the major causes of adult disability worldwide, and post-stroke dementia may affect up to one-third of stroke survivors. This condition could be prevented if we could recognize and treat it earlier. Acupuncture as a complementary treatment for stroke has been shown to be beneficial for subsequent post-stroke rehabilitation. Our study investigated if acupuncture served additional advantages to decreasing the incidence of post-stroke dementia. METHODS We provide a retrospective cohort study from Taiwan National Health Insurance Research Database. This study compared the incidence of post-stroke dementia between cohorts with and without acupuncture treatment by calculating adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of acupuncture associated with post-stroke dementia using Cox proportional hazard regressions. The study group was composed of 9,547 patients who received first hospitalization for the treatment of stroke between 2002 and 2004; of which, 47,735 comparison patients were defined as the control group. The two groups were followed-up until the diagnosis of dementia presented or until the end of 2007. RESULTS The adjusted HRs of developing dementia among patients with stroke was 4.705 times the average (range, 4.353–5.085), and the incidence of dementia was higher in males. The study group tended to have less incidence of all kinds of dementia after acupuncture treatment, and patients without stroke receiving acupuncture had a lower probability of dementia than those untreated during the follow-up period. CONCLUSIONS This study presents evidence that acupuncture serves as an effective and alternative procedure to lower the risk of post-stroke dementia and the overall incidence of dementia in Taiwanese population.
