Comparison of Treatment Outcomes among Sibling Oocytes Using Different Culture Systems-Conventional IVF versus INVOcell Device-And Evaluation of INVOcell User Satisfaction: The INVOcIVF Study

INVOcell is considered an alternative to conventional IVF proposed for intravaginal embryo culture; however, implementation is still low because evidence is scanty regarding its outcome and, most importantly, the device's user satisfaction. Thus, we aim to compare the embryo outcome of sibling oocytes following INVOcell culture with conventional IVF (cIVF) by assessing its clinical outcome (fertilization, blastulation rate, and good embryo quality) and the user satisfaction evaluation based on a local validation questionnaire. A prospective study was done at a university-setting hospital for 12 months (July 2021-2022). The oocytes collected were divided into INVOcell and cIVF groups equally. Inclusion criteria included <40 years old and body mass index (BMI) < 30 kg/m². The pre- and post-satisfaction questionnaires were assessed. In total, 23 women were included following standard controlled ovarian stimulation (COS). The mean age was 32.9, and the mean BMI was 24.9 kg/m². Most of them suffered from tubal factors. A total of 252 oocytes were collected and incubated accordingly (cIVF; 138, INVOcell; 114). The blastulation rate was superior in the INVOcell group (p = 0.16); otherwise, the fertilization rate and good embryo quality were not significantly different between both methods (p > 0.05). Overall, women were satisfied with the INVOcell device as they were adequately advised, follow-up was scheduled, and the lowest score was obtained for all side effects of the device. Although both methods produce similar fertilization rates and good-quality embryos, the blastulation rates were better in the INVOcell group. Functionally, it is a user-friendly device and tolerable. Therefore, INVOcell can be used as an alternative method for reproductive treatment in carefully selected patients without jeopardizing the IVF outcomes.

Ovarian teratoma-associated anti-NMDAR encephalitis in a 12-year-old girl

The association of ovarian teratoma and anti-N-Methyl-Daspartate receptor (anti-NMDAR) is one of the most common autoimmune encephalitis syndromes and it is a serious and potentially fatal pathology that occurs in young women. This case report describes of a pediatric patient with anti-NMDAR encephalitis. A-12-year-old girl presented with abnormal behavior for one week came to Emergency Department of Sarawak General Hospital, Malaysia. She had psychotic spectrum symptoms including suicidal tendency. She was diagnosed with anti-NMDAR encephalitis as positive antibody was seen in her cerebrospinal fluid. She was treated with Injection Immunoglobulin. She turned out to have teratoma which was successfully removed later. Her progress was remarkable after the surgery with the Immunoglobulin. A multi-disciplinary team involving a psychiatrist, neurologist and gynaecologist liaised with intensivist to successfully manage the case and achieve the good outcome.

High-Sensitivity Cardiac Troponin I Levels in Normal and Hypertensive Pregnancy

PURPOSE

The purpose of this study was to examine the association of circulating concentrations of high-sensitivity cardiac troponin I (hs-cTn) in the various trimesters of pregnancy in patients with and without hypertension.

METHODS

This was a prospective cross-sectional study of pregnant and postnatal women aged between 18-35 years with no coexisting diseases. Serum samples were analysed for hs-TnI.

RESULTS

A total of 880 women (mean age = 29.1 years [standard deviation = 5.1 years]) were recruited with 129 (14%), 207 (24%), and 416 (47%) patients in the first, second, and third trimesters, respectively. Ninety (10%) participants were recruited in the postnatal period. During pregnancy 28 (3%) patients were classified as having pregnancy-induced hypertension and 10 (1%) as preeclampsia. High-sensitivity cardiac troponin I was measurable in 546 (62%) participants with a median of 1 ng/L (range 0 to 783 ng/L). Troponin concentrations were above the 99th percentile in 19 (2%) individuals. Patients with pregnancy-induced hypertension and preeclampsia had higher concentrations of hs-TnI (median 11 ng/L [interquartile range (IQR) 6 to 22 ng/L] vs 12ng/L [IQR 3 to 98 ng/L] vs 1 ng/L [IQR 0 to 1 ng/L]). In logistic regression modeling hs-cTnI concentration remained an independent predictor of pregnancy-induced hypertension or preeclampsia in both unadjusted and adjusted models (odds ratio 9.3 [95% confidence interval 5.8 to 16.3] and 11.5 [95% confidence interval 6.3 to 24.1], respectively, per doubling of hs-TnI concentrations).

CONCLUSIONS

Cardiac troponin measured using a high-sensitivity assay is quantifiable in the majority of young pregnant women with 2% of individuals having concentration above the 99th percentile sex-specific threshold. Patients with pregnancy-induced hypertension or preeclampsia had higher cardiac troponin concentrations. Cardiac troponin was a strong independent predictor of pregnancy-induced hypertension or preeclampsia in pregnant and postnatal women.

A randomised controlled trial of expectant management versus surgical evacuation of early pregnancy loss

OBJECTIVE

To show whether a clinically significant difference in success rates exists between expectant and surgical management of early pregnancy loss.

STUDY DESIGN

Randomised controlled trial comparing expectant versus surgical management of early pregnancy loss over a 1-year period from 1st January to 31st December 2009 at Sultanah Aminah Hospital, Johor Bahru. Pregnant women with missed or incomplete miscarriages at gestations up to 14 weeks were recruited in this study. The success rate in the surgical group was measured as curettage performed without any complications during or after the procedure, while the success rate in the expectant group was defined as complete spontaneous expulsion of products of conception within 6 weeks without any complication.

RESULTS

A total of 360 women were recruited and randomised to expectant or surgical management, with 180 women in each group. There was no statistically significant difference in the success rate between the groups and between the different types of miscarriage. With expectant management, 131 (74%) patients had a complete spontaneous expulsion of products of conception, of whom 106 (83%) women miscarried within 7 days. However, the rates of unplanned admissions (18.1%) and unplanned surgical evacuations (17.5%) in the expectant group were significantly higher than the rates (7.4% and 8% respectively) in the surgical group. The complications in both groups were similar.
