Remote IVF: a clinical and laboratory guide to performing remote oocyte retrievals.

The aim of this guide is to describe different scenarios when remote IVF would be needed, considerations around how to plan for the procedure, proper equipment in the procedure room, and proper transportation of oocytes from the procedure room. There are two different scenarios for remote IVF: (1) IVF clinics designed knowing the embryology laboratory is nonadjacent and (2) IVF clinics that routinely provide care to patients in their clinic and want to provide care to those who are ineligible for a retrieval under anesthesia in an outpatient facility. This guide will focus on both scenarios. Much of the advice can be used for IVF clinics that routinely perform oocyte retrievals nonadjacent to their embryology laboratories. Special considerations are needed when patients with complex comorbidities require high-level of care and hospital-level monitoring while under anesthesia and/or post-oocyte retrieval, and are thus unable to be treated in the standard facility. For these reasons we have created a comprehensive guide to nonadjacent, or off-site, oocyte retrievals for reproductive endocrinology and infertility (REI) physicians, nurses, and embryologists to use when planning care for IVF patients. Going forward, we will refer to both these scenarios as remote IVF.

Outcomes of assisted reproductive technology procedures performed on weekdays versus weekends: a retrospective cohort study.

PURPOSE: To evaluate if assisted reproductive technology (ART) outcomes are different based on whether procedures - oocyte retrieval, insemination, embryo biopsy, or embryo transfer - are performed on a weekday versus weekend/holiday. METHODS: Retrospective cohort study of all patients ≥ 18 years old who underwent oocyte retrieval for in vitro fertilization or oocyte banking (n = 3,197 cycles), fresh or natural-cycle frozen embryo transfers (n = 1,739 transfers), or had embryos biopsied for pre-implantation genetic testing (n = 4,568 embryos) in a large academic practice from 2015-2020. The primary outcomes were as follows: oocyte maturity for oocyte retrievals; fertilization rate for insemination; rate of no result on pre-implantation genetic testing for embryo biopsy; and live birth rate for embryo transfers. RESULTS: The average number of procedures performed per embryologist per day was higher on weekends/holidays than weekdays. For oocyte retrievals performed on weekdays vs. weekends/holidays, there was no difference in oocyte maturity rate (88% vs 88%). There was no difference in the fertilization rate (82% vs 80%) in cycles that had intracytoplasmic sperm injection performed on weekdays vs. weekends/holidays. No difference was found in the no result rate for embryos biopsied on weekdays vs. weekends/holidays (2.5% vs 1.8%). Finally, there was no difference by weekday vs. weekend/holiday in the live birth rate per transfer among all transfers (39.6% vs 36.1%), or when stratified by fresh (35.1% vs 34.9%) or frozen embryo transfer (49.7% vs. 39.6%). CONCLUSION: We found no differences in ART outcomes among women who had their oocyte retrievals, inseminations, embryo biopsies, or embryo transfers performed on weekdays versus weekends/holidays.

Fertility preservation outcomes in women with gliomas: a retrospective case-control study.

PURPOSE: With advances in cancer therapy, reproductive-aged women can look forward to a life post-malignancy. Fortunately, fertility preservation (FP) may provide relief from potential infertility caused by cancer or associated caustic treatments. Outcomes of FP in pre-treatment reproductive-aged women with gliomas have not been previously characterized. METHODS: Between 2007 and 2018, 10 patients undergoing FP prior to chemotherapy and/or radiation treatment for gliomas were identified at Brigham and Women's Hospital. They were matched 3:1 to male-factor infertility patients by age ± 1 year. RESULTS: Patients with gliomas had significantly lower baseline anti-Müllerian hormone levels than male-factor infertility controls (2.37 vs 5.16 ng/mL, p = 0.002, log transformed). Despite higher starting (350 vs. 240 IU, p = 0.004) and total gonadotropin doses (4270 vs. 2270 IU, p < 0.001) over a similar stimulation duration (12.1 vs. 11.1 days, p = 0.219), cancer patients had lower peak estradiol levels (1420 vs. 2245 pg/mL, p = 0.003). The total number of follicles on the day of trigger (14.1 vs. 15.6, p = 0.284), the number of oocytes retrieved (18.4 vs. 20.5, p = 0.618), and the percentage of mature oocytes (69.9 vs. 73.8%, p = 0.076) were similar between cases and controls. One patient returned for a cryopreserved embryo transfer and delivered a healthy child. CONCLUSIONS: Patients undergoing FP prior to chemotherapy and/or radiation for a glioma achieve satisfactory FP outcomes and should be appropriately counseled regarding the opportunity to family-build after treatment.

The impact of polycystic ovary syndrome and body mass index on the absorption of recombinant human follicle stimulating hormone.

PURPOSE: Women with polycystic ovary syndrome (PCOS) have an increased ovarian responsiveness to exogenous recombinant follicle stimulating hormone (rFSH) but also have high rates of obesity, which is known to affect serum FSH concentrations following exogenous injection. The purpose of this study was to compare rFSH absorption and ovarian response between lean and overweight/obese PCOS subjects and normo-ovulatory controls. METHODS: Fourteen women with PCOS aged 18-42 years old with a BMI of 18.5-24.9 kg/m2 (normal) or 25.0-40.0 kg/m2 (overweight/obese) and eleven normo-ovulatory controls matched by age and BMI were included. After downregulation with oral contraceptives, participants were administered a single subcutaneous injection of 225 IU rFSH and underwent serial blood draws over 72 h. RESULTS: Lean PCOS subjects exhibited a significantly higher area under the curve (AUC) of baseline-corrected serum FSH over 72 h when compared with overweight/obese PCOS subjects (183.3 vs 139.8 IU*h/L, p = 0.0002), and lean, normo-ovulatory women had a significantly higher AUC FSH when compared with overweight/obese, normo-ovulatory women (193.3 vs 93.8 IU*h/L, p < 0.0001). Within overweight/obese subjects, those with PCOS had a significantly higher AUC FSH compared with normo-ovulatory controls (p = 0.0002). Lean PCOS subjects similarly had the highest AUC of baseline-corrected estradiol (6095 pg h/mL), compared with lean normo-ovulatory subjects (1931 pg h/mL, p < 0.0001) and overweight/obese PCOS subjects (2337 pg h/mL, p < 0.0001). CONCLUSION: Lean PCOS subjects exhibited significantly higher baseline-corrected FSH and estradiol levels following rFSH injection compared with overweight/obese PCOS subjects with similar ovarian reserve markers. Amongst overweight/obese subjects, those with PCOS had significantly higher FSH and E2 levels when compared with normo-ovulatory controls.

Non-tubal Ectopic Pregnancies: Overview and Treatment via Local Injection.

Ectopic pregnancies account for 1.5% to 2% of all pregnancy in the United States. Of these, approximately 10% implant in nontubal locations, including the abdominal cavity, cervix, ovary, interstitial portion of the fallopian tube, broad ligament, the uterine cornua, or within a cesarean section scar. Because these pregnancies tend to present later than typical tubal pregnancies, they have been associated with greater maternal morbidity and mortality. Advances in ultrasound technology have allowed for earlier diagnosis of nontubal ectopic pregnancies, which in turn has led to the development of novel minimally invasive techniques to manage them. One of these methods involves the local injection of 1 of several agents directly into the ectopic pregnancy. In this article we provide a guide to this technique of local injection, including an overview of the potential agents that can be used, and review the diagnostic and specific ultrasound criteria, other possible treatment options, and overall outcomes for nontubal ectopic pregnancies.

National survey on use of time-lapse imaging systems in IVF laboratories.

PURPOSE: Several time-lapse imaging (TLI) systems for non-invasive continuous monitoring of developing embryos are currently available. The present study explored the prevalence, means of acquisition, and clinical application of TLI systems in USA in vitro fertilization (IVF) laboratories. METHODS: An online cross-sectional survey of 294 USA IVF laboratory directors was conducted in February and March 2016. Those directing more than one laboratory were asked to complete the survey for their home program and for their smallest laboratory by number of IVF/intracytoplasmic sperm injection (ICSI) cycle starts. Use of TLI was analyzed using logistic regression to calculate odds ratios (OR). RESULTS: Of 294 directors surveyed, 162 (55%) reported data on 204 laboratories. Thirty-five laboratories (17%) possessed at least one TLI system (median 2, interquartile range 1-4, total range 1-11). The more oocyte retrievals a laboratory performed annually, the more likely the laboratory was to possess a TLI system. Fifteen laboratories (43%) purchased their own systems, while others leased, loaned, or received donated systems. Twenty-five laboratories (71%) reported using TLI for embryo selection; all used TLI always, or usually, in combination with standard morphology evaluation. Twenty laboratories (80%) offered TLI to all patients. Some laboratories charged patients for TLI. Directors with TLI systems were more inclined to believe that TLI has value for embryo selection in clinical IVF. CONCLUSIONS: TLI system possession in USA IVF laboratories is low, although positively associated with the number of retrievals performed and with directors' opinions on the technology's utility. Over 70% of laboratories with TLI systems use them clinically, and less than half purchased their systems.

Utility of Repeat Uterine Cavity Evaluation in the Infertility Workup.

Background: Uterine cavity abnormalities contribute to infertility. The purpose of this study was to evaluate the incidence, recurrence rates, and risk factors for uterine cavity abnormalities in women undergoing infertility workup and treatment, focusing on the utility of routinely repeated imaging. Methods: Retrospective cohort study at single academic medical center of 833 infertile women who had uterine cavity evaluations performed at least 9 months apart. Results: Of 833 eligible patients, 664 (79.7%) had normal initial imaging and 169 (20.3%) had abnormal initial imaging. Among the former, 10% had abnormal uterine cavity on repeat saline infusion sonohysterography (SIS); among the latter, 32% had abnormal repeat SIS [Chi-square p < 0.0001, risk ratio 2.30 (95% confidence interval 1.85-2.86)]. On average, 23.1 ± 13.6 months passed between studies. Regardless of initial imaging findings, women with abnormal repeat SIS were older than those with normal repeat SIS, with no difference in time elapsed between studies. There were no associations between repeat imaging outcomes and body mass index, uterine instrumentation, number of treatment cycles, or maximum peak estradiol levels in a single cycle between studies. There was no difference in live birth rate among cycles started within 1 year after repeat SIS across groups. Conclusions: Uterine cavity abnormalities were found in 10% of patients on repeat imaging despite initially normal testing. No risk factors for cavity abnormality on repeat imaging were identified besides age and prior abnormality. It would be prudent to continue performing routine repeat uterine cavity evaluation for women undergoing fertility treatment, particularly if corrective measures had been taken in the past.

Disrupted methylation patterns at birth persist in early childhood: a prospective cohort analysis.

BACKGROUND: Alterations in the epigenome are a risk factor in multiple disease states. We have demonstrated in the past that disruption of the epigenome during early pregnancy or periconception, as demonstrated by altered methylation, may be associated with both assisted reproductive technology and undesirable clinical outcomes at birth, such as low birth weight. We have previously defined this altered methylation, calculated based on statistical upper and lower limits of outlier CpGs compared to the population, as an 'outlier methylation phenotype' (OMP). Our aim in this study was to determine whether children thus identified as possessing an OMP at birth by DNA methylation in cord blood persist as outliers in early childhood based on salivary DNA methylation. RESULTS: A total of 31 children were included in the analysis. Among 24 children for whom both cord blood DNA and salivary DNA were available, DNA methylation patterns, analyzed using the Illumina Infinium MethylationEPIC BeadChip (850 K), between cord blood at birth and saliva in childhood at age 6-12 years remain stable (R2 range 0.89-0.97). At birth, three out of 28 children demonstrated an OMP in multiple cord blood datasets and hierarchical clustering. Overall DNA methylation among all three OMP children identified as outliers at birth was remarkably stable (individual R2 0.908, 0.92, 0.915), even when only outlier CpG sites were considered (R2 0.694, 0.738, 0.828). CONCLUSIONS: DNA methylation signatures in cord blood remain stable over time as demonstrated by a strong correlation with epigenetic salivary signatures in childhood. Future work is planned to identify whether a clinical phenotype is associated with OMP and, if so, could undesirable clinical outcomes in childhood and adulthood be predicted at birth.

Association of a Pediatric Gynecology eLearning Module With Resident Knowledge and Clinical Skills: A Randomized Controlled Trial.

OBJECTIVE: To assess whether a pediatric and adolescent gynecology electronic learning (eLearning) module improves knowledge and clinical performance among obstetrics and gynecology residents. METHODS: We conducted a multi-institutional, single-blinded, randomized controlled trial across four university programs; three had pediatric and adolescent gynecology rotations, and two had pediatric and adolescent gynecology fellowship-trained faculty. Applying permutated block randomization, residents were randomized to no intervention or completion of a validated eLearning module on prepubertal bleeding. All residents subsequently completed a pediatric and adolescent gynecology-related knowledge assessment that queried understanding of prepubertal bleeding and an objective structured clinical examination that assessed history collection, performance of a prepubertal genital examination, vaginal culture, and vaginoscopy for a pediatric patient. Objective structured clinical examinations were videotaped and reviewed by two faculty, blinded to randomization group; interrater reliability score was 97%. We calculated descriptive frequencies and compared randomization groups using χ analyses and Fisher exact tests for categorical variables, and median tests for continuous variables; a value of P<.05 was considered significant. RESULTS: From July 2018 to June 2019, we invited 115 residents to participate; 97 (83%) completed both objective structured clinical examination and follow-up knowledge assessments. Most were female (91%) and the majority reported limited pediatric and adolescent gynecology didactic or clinical experience, with 36% reporting prior didactics on prepubertal vaginal bleeding and 33% reporting prior exposure to the prepubertal genital examination. Forty-five participants (46%) were randomized to the module and groups were similar across training levels. Residents assigned to the module scored significantly higher on the knowledge assessment (4/5 vs 2/5, P<.001) and objective structured clinical examination (13/16 vs 7/16, P<.001) and were more likely to avoid a speculum in the examination of a pediatric patient (95.6% vs 57.7%, P<.001). CONCLUSION: Our pediatric and adolescent gynecology eLearning module resulted in improved short-term resident knowledge and simulated clinical skills among obstetrics and gynecology residents. Applying this learning technique in other programs may help address deficiencies in pediatric and adolescent gynecology education and training.

Hyperandrogenism in menopause: a case report and literature review.

Hyperandrogenism is an uncommon diagnosis in postmenopausal women. In this case, we report on a 69-year-old postmenopausal woman who presented with several months of worsening hirsutism of the face, neck, and chin, which was confirmed on examination. Laboratory testing revealed markedly elevated testosterone levels and typical post-menopausal gonadotropin levels. Transvaginal ultrasonography and pelvic and abdominal magnetic resonance imaging (MRI) failed to reveal an ovarian or adrenal abnormality. The patient was a poor surgical candidate and was counseled to start on gonadotropin releasing hormone (GnRH) agonist therapy. Administration of leuprolide resulted in a dramatic decline in testosterone levels. The patient reported significant "hot flashes", difficulty sleeping, anxiety, and depression secondary to treatment, and patient discontinued leuprolide therapy 3 months after initiation. To our knowledge, this is the first case that describes a woman being treated with a GnRH agonist for hyperandrogenism subsequently discontinuing GnRH agonist treatment due to significant side-effects. This case also highlights the difficulty of prescribing appropriate but off-label use of expensive medications not covered by insurance in a senior population of limited income.

Evidence for the ubiquitin protease UBP43 as an antineoplastic target.

New pharmacologic targets are needed for lung cancer. One candidate pathway to target is composed of the E1-like ubiquitin-activating enzyme (UBE1L) that associates with interferon-stimulated gene 15 (ISG15), which complexes with and destabilizes cyclin D1. Ubiquitin protease 43 (UBP43/USP18) removes ISG15 from conjugated proteins. This study reports that gain of UBP43 stabilized cyclin D1, but not other D-type cyclins or cyclin E. This depended on UBP43 enzymatic activity; an enzymatically inactive UBP43 did not affect cyclin D1 stability. As expected, small interfering RNAs that reduced UBP43 expression also decreased cyclin D1 levels and increased apoptosis in a panel of lung cancer cell lines. Forced cyclin D1 expression rescued UBP43 apoptotic effects, which highlighted the importance of cyclin D1 in conferring this. Short hairpin RNA-mediated reduction of UBP43 significantly increased apoptosis and reduced murine lung cancer growth in vitro and in vivo after transplantation of these cells into syngeneic mice. These cells also exhibited increased response to all-trans-retinoic acid, interferon, or cisplatin treatments. Notably, gain of UBP43 expression antagonized these effects. Normal-malignant human lung tissue arrays were examined independently for UBP43, cyclin D1, and cyclin E immunohistochemical expression. UBP43 was significantly (P < 0.01) increased in the malignant versus normal lung. A direct relationship was found between UBP43 and cyclin D1 (but not cyclin E) expression. Differential UBP43 expression was independently detected in a normal-malignant tissue array with diverse human cancers. Taken together, these findings uncovered UBP43 as a previously unrecognized antineoplastic target.

Blockade of the ubiquitin protease UBP43 destabilizes transcription factor PML/RARα and inhibits the growth of acute promyelocytic leukemia.

More effective treatments for acute promyelocytic leukemia (APL) are needed. APL cell treatment with all-trans-retinoic acid (RA) degrades the chimeric, dominant-negative-acting transcription factor promyelocytic leukemia gene (PML)/RARα, which is generated in APL by chromosomal translocation. The E1-like ubiquitin-activating enzyme (UBE1L) associates with interferon-stimulated gene ISG15 that binds and represses PML/RARα protein. Ubiquitin protease UBP43/USP18 removes ISG15 from conjugated proteins. In this study, we explored how RA regulates UBP43 expression and the effects of UBP43 on PML/RARα stability and APL growth, apoptosis, or differentiation. RA treatment induced UBE1L, ISG15, and UBP43 expression in RA-sensitive but not RA-resistant APL cells. Similar in vivo findings were obtained in a transgenic mouse model of transplantable APL, and in the RA response of leukemic cells harvested directly from APL patients. UBP43 knockdown repressed PML/RARα protein levels and inhibited RA-sensitive or RA-resistant cell growth by destabilizing the PML domain of PML/RARα. This inhibitory effect promoted apoptosis but did not affect the RA differentiation response in these APL cells. In contrast, elevation of UBP43 expression stabilized PML/RARα protein and inhibited apoptosis. Taken together, our findings define the ubiquitin protease UBP43 as a novel candidate drug target for APL treatment.
