Endometrial compaction does not predict live birth in single euploid frozen embryo transfers: a prospective study.

STUDY QUESTION: Is there a relationship between endometrial compaction and live birth in euploid frozen embryo transfer (FET) cycles? SUMMARY ANSWER: Live birth rates (LBRs) were similar in both patients that demonstrated endometrial compaction or no compaction in single euploid FETs. WHAT IS KNOWN ALREADY: There has been increasing interest in the correlation between endometrial compaction and clinical outcomes but there has been conflicting evidence from prior investigations. STUDY DESIGN, SIZE, DURATION: This was a prospective observational study from 1 September 2020 to 9 April 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS: This study was performed at a single, academically affiliated fertility center in which patients who had an autologous single euploid FET using a programmed or modified natural cycle protocol were included. All embryos had trophectoderm biopsy for preimplantation genetic testing for aneuploidy followed by vitrification at the blastocyst stage. Two ultrasound measurements of endometrial thickness (EMT) were obtained. The first measurement (T1) was measured transvaginally within 1 day of initiation of progesterone or ovulation trigger injection, and a second EMT (T2) was measured transabdominally at the time of embryo transfer (ET). The primary outcome (LBR) was based on the presence and proportion of compaction (percentage difference in EMT between T1 and T2). MAIN RESULTS AND THE ROLE OF CHANCE: Of the 186 participants included, 54%, 45%, 35%, 28% and 21% of women exhibited >0%, ≥5%, ≥10%, ≥15% and ≥20% endometrial compaction, respectively. Endometrial compaction was not predictive of live birth at any of the defined cutoffs. A sub-analysis stratified by FET protocol type (n = 89 programmed; n = 97 modified natural) showed similar results. LIMITATIONS, REASONS FOR CAUTION: There was the potential for measurement error in the recorded EMTs. The T2 measurement was performed transabdominally, which may cause potential measurement error, as it is generally accepted that transvaginal measurements of EMT are more accurate, though, any bias is expected to be non-differential. The sub-analysis performed looking at FET protocol type was underpowered and should be interpreted with caution. Our study, however, represents a pragmatic approach, as it allowed patients to avoid having to come in for an extra transvaginal ultrasound the day before or on the day of ET. WIDER IMPLICATIONS OF THE FINDINGS: Assessing endometrial compaction may lead to unnecessary cycle cancellation. However, further studies are needed to determine if routine screening for endometrial compaction would improve clinical outcomes. STUDY FUNDING/COMPETING INTEREST(S): No authors report conflicts of interest or disclosures. There was no study funding. TRIAL REGISTRATION NUMBER: NCT04330066.

Unusual presentation of stiff-person syndrome in a patient with type 1 diabetes mellitus.

Stiff-person syndrome (SPS) is a rare, autoimmune, neurological disorder that often occurs concurrently with other autoimmune disorders, such as type 1 diabetes mellitus, pernicious anaemia, vitiligo and Hashimoto's thyroiditis. It also can manifest as a paraneoplastic syndrome. Although SPS classically presents with truncal and appendicular stiffness and lumbar hyperlordosis, it can present focally in a single limb (termed stiff-limb syndrome). Here, we describe a woman with stiff-limb syndrome who initially presented with concerns about right foot swelling and pain. She also was positive for anti-GAD65 (anti-GAD2) antibodies. With treatment, she regained the ability to drive and ambulate without a walker, and she had a noted reduction in stimulus-induced spasms.

Fluorescence lifetime imaging microscopy (FLIM) detects differences in metabolic signatures between euploid and aneuploid human blastocysts.

STUDY QUESTION: Can non-invasive imaging with fluorescence lifetime imaging microscopy (FLIM) detect metabolic differences in euploid versus aneuploid human blastocysts? SUMMARY ANSWER: FLIM has identified significant metabolic differences between euploid and aneuploid blastocysts. WHAT IS KNOWN ALREADY: Prior studies have demonstrated that FLIM can detect metabolic differences in mouse oocytes and embryos and in discarded human blastocysts. STUDY DESIGN, SIZE, DURATION: This was a prospective observational study from August 2019 to February 2020. Embryo metabolic state was assessed using FLIM to measure the autofluorescence metabolic factors nicotinamide adenine dinucleotide dehydrogenase together with nicotinamide adenine phosphate dinucleotide dehydrogenase (NAD(P)H) and flavin adenine dinucleotide (FAD). Eight metabolic FLIM parameters were obtained from each blastocyst (four for NAD(P)H and four for FAD): short (T1) and long (T2) fluorescence lifetime, fluorescence intensity (I) and fraction of the molecules engaged with enzymes (F). The redox ratio (NAD(P)H-I)/(FAD-I) was also calculated for each image. PARTICIPANTS/MATERIALS, SETTING, METHODS: This study was performed at a single academically affiliated centre where there were 156 discarded frozen blastocysts (n = 17 euploids; 139 aneuploids) included. Ploidy status was determined by pre-implantation genetic testing for aneuploidy (PGT-A). Discarded human blastocysts were compared using single FLIM parameters. Additionally, inner cell mass (ICM) and trophectoderm (TE) were also evaluated. Multilevel models were used for analysis. A post-hoc correction used Benjamini-Hochberg's false discovery rate, at a q-value of 0.05. MAIN RESULTS AND THE ROLE OF CHANCE: Comparing euploid (n = 17) versus aneuploid (n = 139) embryos, a significant difference was seen in NAD(P)H-F (P < 0.04), FAD-I (P < 0.04) and redox ratio (P < 0.05). Euploid ICM (n = 15) versus aneuploid ICM (n = 119) also demonstrated significantly different signatures in NAD(P)H-F (P < 0.009), FAD-I (P < 0.03) and redox ratio (P < 0.03). Similarly, euploid TE (n = 15) versus aneuploid TE (n = 119) had significant differences in NAD(P)H-F (P < 0.0001) and FAD-I (P < 0.04). LIMITATIONS, REASONS FOR CAUTION: This study utilized discarded human blastocysts, and these embryos may differ metabolically from non-discarded human embryos. The blastocysts analysed were vitrified after PGT-A biopsy and it is unclear how the vitrification process may affect the metabolic profile of blastocysts. Our study was also limited by the small number of rare donated euploid embryos available for analysis. Euploid embryos are very rarely discarded due to their value to patients trying to conceive, which limits their use for research purposes. However, we controlled for the imbalance with the bootstrap resampling analysis. WIDER IMPLICATIONS OF THE FINDINGS: These findings provide preliminary evidence that FLIM may be a useful non-invasive clinical tool to assist in identifying the ploidy status of embryos. STUDY FUNDING/COMPETING INTEREST(S): The study was supported by the Blavatnik Biomedical Accelerator Grant at Harvard University. Becker and Hickl GmbH and Boston Electronics sponsored research with the loaning of equipment for FLIM. D.J.N. is an inventor on patent US20170039415A1.

Comprehensive Perioperative Approach to Complex Spine Deformity Management.

OBJECTIVE: Study perioperative strategies for optimizing neuroprotection in complex spine deformity correction surgery. METHODS: We report the case of a patient with severe lumbar dextroscoliosis, thoracolumbar junction hyperkyphosis with a 40-degree Cobb angle levoconvex scoliosis who underwent spinal deformity correction with loss of neuromonitoring during surgery. We performed a literature review on perioperative management of complex spine deformity. RESULTS: A 50-year-old man presented with lumbar pain and right L4 radiculopathy. Surgical intervention for deformity correction and decompression was indicated with T4-L4 posterior instrumentation L2/L3 and L3/L4 transforaminal lumbar interbody fusion. Surgery was aborted due to the loss of neuromonitoring. Postsurgery, the patient had left sensory deficit and the neurocritical care team clinically suspected and deduced the anatomic location of the spinal cord compression. Magnetic resonance imaging confirmed a T10-T11 hyperintensity suggestive of cord ischemia due to osteophyte compressing the spinal cord. The patient underwent a second corrective surgery with no intraoperative events and has no long-term neurological sequela. CONCLUSIONS: This case illustrates that a comprehensive perioperative approach and individualized risk factor assessment is useful in complex spine deformity surgery. Further research is needed to determine how this individualized comprehensive approach can lead to intraoperative and postoperative countermeasures that improved spine surgery outcomes. LEVEL OF EVIDENCE: Level V.

Urine levels of the polyglutamine ataxin-3 protein are elevated in patients with spinocerebellar ataxia type 3.

INTRODUCTION: Accumulation of polyglutamine (polyQ) ataxin-3 (ATXN3) contributes to the pathobiology of spinocerebellar ataxia type 3 (SCA3). Recently, we showed that polyQ ATXN3 is elevated in the plasma and cerebrospinal fluid (CSF) of SCA3 patients, and has the potential to serve as a biological marker for this disease [1]. Based on these findings, we investigated whether polyQ ATXN3 can also be detected in urine samples from SCA3 patients. METHODS: We analyzed urine samples from 30 SCA3 subjects (including one pre-symptomatic subject), 35 subjects with other forms of ataxia, and 37 healthy controls. To quantify polyQ ATXN3 protein levels, we used our previously developed immunoassay. RESULTS: PolyQ ATXN3 can be detected in the urine of SCA3 patients, but not in urine samples from healthy controls or other forms of ataxia. There was a significant statistical association between polyQ ATXN3 levels in urine samples and those in plasma. Further, the levels of polyQ ATXN3 urine associated with an earlier age of SCA3 disease onset. CONCLUSION: As clinical trials for SCA3 advance, urine polyQ ATXN3 protein has potential to be a useful, non-invasive and inexpensive biomarker for SCA3.

Reproductive counseling and pregnancy outcomes after radical trachelectomy for early stage cervical cancer.

OBJECTIVE: To evaluate patient perceptions of preoperative reproductive counseling and to evaluate complications and pregnancy outcomes in women who had radical trachelectomy (RT) for early stage cervical cancer. METHODS: Patients who underwent RT from January 1, 2004, through July 31, 2017, and had been cancer free for more than 1 year after RT were eligible; consented patients were sent a 16-item online survey. RESULTS: Of the 58 eligible patients, 39 patients (67%) completed the questionnaire. Eighteen patients (46%) reported receiving reproductive counseling and 26 (68%) reported receiving counseling about pregnancy risks and complications prior to RT, mainly delivered by gynecologic oncologists. Twenty-nine patients (74%) reported having a complication after RT, and cervical stenosis was the most common complication, occurring in 13 patients (33%). Twenty-four patients actively attempted to conceive after RT, and 20 pregnancies were achieved in 13 patients for a pregnancy rate of 54%. Eight pregnancies were spontaneous and 12 required a fertility treatment. There were 5 spontaneous first-trimester miscarriages; 14 of the 20 pregnancies (70%) resulted in live births. The median time to conception was 13.5 months (range, 1-120). CONCLUSION: A significant proportion of women with early stage cervical cancer do not receive adequate reproductive counseling before RT, and many women undergoing RT experience complications that can negatively impact their fertility. We recommend a preoperative consultation with a reproductive endocrinologist for all patients considering RT.

Accuracy of Intraoperative Frozen Section Diagnosis of Borderline Ovarian Tumors by Hospital Type.

STUDY OBJECTIVE: To compare the accuracy of frozen section diagnosis of borderline ovarian tumors among 3 distinct types of hospital-academic hospital with gynecologic pathologists, academic hospital with nongynecologic pathologists, and community hospital with nongynecologic pathologists-and to determine if surgical staging alters patient care or outcomes for women with a frozen section diagnosis of borderline ovarian tumor. DESIGN: Retrospective study (Canadian Task Force classification II-1). SETTING: Tertiary care, academic, and community hospitals. PATIENTS: Women with an intraoperative frozen section diagnosis of borderline ovarian tumor at 1 of 3 types of hospital from April 1998 through June 2016. INTERVENTIONS: Comparison of final pathology with intraoperative frozen section diagnosis. MEASUREMENTS AND MAIN RESULTS: Two hundred twelve women met the inclusion criteria. The frozen section diagnosis of borderline ovarian tumor correlated with the final pathologic diagnosis in 192 of 212 cases (90.6%), and the rate of correlation did not differ among the 3 hospital types (p = .82). Seven tumors (3.3%) were downgraded to benign on final pathologic analysis and 13 (6.1%) upgraded to invasive carcinoma. The 3 hospital types did not differ with respect to the proportion of tumors upgraded to invasive carcinoma (p = .62). Mucinous (odds ratio, 7.1; 95% confidence interval, 2.1-23.7; p = .002) and endometrioid borderline ovarian tumors (odds ratio, 32.4; 95% confidence interval, 1.8-595.5; p = .02) were more likely than serous ovarian tumors to be upgraded to carcinoma. Only 88 patients (41.5%) underwent lymphadenectomy, and only 1 (1.1%) had invasive carcinoma in a lymph node. CONCLUSIONS: A frozen section diagnosis of borderline ovarian tumor correlates with the final pathologic diagnosis in a variety of hospital types.

The Relationship of Assisted Reproductive Technology on Perinatal Outcomes in Triplet Gestations.

OBJECTIVE: To assess whether assisted reproductive technology (ART) is associated with increased risk of adverse perinatal outcomes in triplet gestations compared with spontaneous conception. STUDY DESIGN: Secondary analysis of a multicenter randomized trial for the prevention of preterm birth in multiple gestations. Triplets delivered at ≥ 24 weeks were studied. The primary outcome was the rate of composite neonatal morbidity (CNM) that included one or more of the following: bronchopulmonary dysplasia, respiratory distress syndrome, necrotizing enterocolitis, culture proven sepsis, pneumonia, retinopathy of prematurity, intraventricular hemorrhage, periventricular leukomalacia, or perinatal death. RESULTS: There were 381 triplets (127 women) of which 89 patients conceived via ART and 38 patients spontaneously. Women with ART were more likely to be older, Caucasian, married, nulliparous, have higher level of education, and develop pre-eclampsia. Spontaneously conceived triplets were more likely to delivery at an earlier gestation (31.2 ± 3.5 vs 32.8 ± 2.7 weeks) (p = 0.009) with a lower birth weight (p < 0.001). After adjusting for confounders, no differences were noted in culture proven sepsis, perinatal death, CNM, respiratory distress syndrome, or Apgar score < 7 at 5 minutes. All remaining perinatal outcomes were similar. CONCLUSION: Triplets conceived by ART had similar perinatal outcomes compared with spontaneously conceived triplets.

Factors influencing fertility-sparing treatment for gynecologic malignancies: A survey of Society of Gynecologic Oncology members.

OBJECTIVES: This study aims to examine practice patterns of gynecologic oncologists (GO) regarding fertility-sparing treatments (FST) for gynecology malignancies and explores attitudes toward collaboration with reproductive endocrinologists (RE). METHODS: An anonymous 23-question survey was sent to 1087 GO with a 14.0% completion rate. Descriptive statistics, Fisher's exact test, and Chi-square tests were used for data analysis. RESULTS: The majority of GOs offer FST for gynecologic malignancies. Providers seeing larger numbers of reproductive age women were more likely to consider cancer prognosis (p<0.03) and cancer stage (p<0.01) as key factors. Providers in the Midwestern US considered socioeconomic status more often when offering FST than those in the South (p<0.04). Those practicing in urban settings were more likely to feel that collaborating with a RE prior to treatment could improve treatment planning for women considering FST (p<0.02). Finally, providers in urban or suburban areas more often felt collaboration with a RE improves pregnancy outcomes in women who pursue FST (p<0.01, p<0.02) compared to rural practitioners. CONCLUSIONS: While FST offers women the chance to pursue pregnancy after cancer, there are minimal data on factors that influence whether FST is offered and if collaboration with a RE is sought in the management of these patients. The number of reproductive age women seen, geographic location, and practice setting are important variables that may influence current practice. Understanding these factors can help identify opportunities to improve oncologic and reproductive outcomes of this patient population.

Role of cervical cytology in surveillance after radical trachelectomy for cervical cancer.

OBJECTIVE: There are currently no standard guidelines on the use of Papanicolaou (Pap) tests for surveillance after radical trachelectomy for cervical cancer. The goal of this study was to determine the usefulness of Pap tests in routine surveillance after radical trachelectomy for cervical cancer. METHODS: Cervical cancer patients who underwent radical trachelectomy from January 2004 through October 2015 and subsequently had at least one Pap test were retrospectively identified. Demographic and clinical characteristics were described and compared between patients with and without at least one abnormal Pap test. The Kaplan-Meier method was used to estimate time to first abnormal Pap test. RESULTS: Forty-one patients met inclusion criteria. Of these, 30 (73%) had at least one year in which more than one Pap test per year was obtained. Twenty-four (59%) had at least one abnormal Pap test. Of 238 total Pap tests collected, 44 (18%) were abnormal. The most common abnormality was ASCUS (52%, n=23). Other findings included LSIL (20%, n=9), HSIL (2%, n=1), and AGUS (25%, n=11). Median time from radical trachelectomy to first abnormal Pap test was 17.2months (range, 11.8-86.3). No patient had disease recurrence. Surgery type (laparoscopic, open, or robotic), trachelectomy specimen size, histology, device for stenosis prevention (pediatric Foley catheter or Smit Sleeve), and cerclage placement were not significant predictors of an abnormal Pap test. CONCLUSIONS: The rate of abnormal Pap tests after radical trachelectomy is high; however, the clinical significance of such abnormalities appears limited. The routine use of cervical cytology as surveillance after radical trachelectomy does not appear to substantially impact management decisions.
