Growth hormone supplementation during ovarian stimulation improves oocyte and embryo outcomes in IVF/PGT-A cycles of women who are not poor responders.

PURPOSE: To determine the effect of human growth hormone (GH) supplementation during ovarian stimulation in women undergoing IVF/PGT-A cycles, who do not meet the Bologna criteria for poor ovarian response (POR). METHODS: This is a retrospective cohort study of 41 women with suboptimal outcomes in their first cycle of IVF/PGT-A including lower than expected number of MII oocytes, poor blastulation rate, and/or lower than expected number of euploid embryos for their age, who underwent a subsequent IVF/PGT-A cycle with the same fixed dose gonadotropin protocol and adjuvant GH treatment. Daily cotreatment with GH started with first gonadotrophin injection. The IVF cycle outcomes were compared between the control and GH cycle using the Wilcoxon-Signed Rank test. RESULTS: The total number of biopsied blastocysts (mean ± SD; 2.0 ± 1.6 vs 3.5 ± 3.2, p = 0.009) and euploid embryos (0.8 ± 1.0 vs 2.0 ± 2.8, p = 0.004) were significantly increased in the adjuvant GH cycle compared to the control cycle. The total number of MII oocytes also trended to be higher in the GH cycle (10.2 ± 6.3 vs 12.1 ± 8.3, p = 0.061). The overall blastulation and euploidy rate did not differ between the control and treatment cycle. CONCLUSION: Our study uniquely investigated the use of adjuvant GH in IVF/PGT-A cycles in women without POR and without a priori suspicion for poor outcome based on their clinical parameters. Our study presents preliminary evidence that GH supplementation in these women is beneficial and is associated with an increased number of blastocysts for biopsy and greater number of euploid embryos for transfer.

Iterative approach to journal club.

To identify, evaluate and refine a journal club (JC) format that increases faculty and resident engagement. An initial needs assessment followed by a trial of three JC formats: traditional single presenter, debate style and facilitated small group discussion was piloted over 6 months. Anonymous feedback was collected. The facilitated small group format was chosen. Narrative and quantitative feedback were collected from residents and faculty at 6-month intervals for the next 24 months. Changes to the format were made using feedback. Fourteen residents (n=20, 70%) and 10 faculty (n=20, 50%) completed baseline surveys. We initially observed low resident (8/14, 57%) interest in JCs. Additionally, 9/14 (64%) of residents and 1/15 (7%) of faculty reported low confidence presenting articles publicly. After implementation of the new JC format, resident reported enjoyment, on a scale of 1-5, improved from 3.6 to 4.4 (p<0.01). We observed improvement in resident confidence in the ability to critique a paper (2.7 to 4.1, p<0.01) and in confidence speaking in front of both peers (3.8 to 4.6, p<0.01) and faculty (3.0 to 3.8, p=0.04). Faculty confidence with literature critique decreased (from 4.2 to 3.8), but enjoyment remained stable (4.3 to 4.2). A facilitated small group JC format was preferred in our programme. We observed measurable improvements in both resident interest and confidence, as well as sustained faculty interest in JCs. We fostered an environment of inquiry and identified areas of continued professional development.

PEGylated E. coli asparaginase desensitization: an effective and feasible option for pediatric patients with acute lymphoblastic leukemia who have developed hypersensitivity to pegaspargase in the absence of asparaginase Erwinia chrysanthemi availability.

Asparaginase is an important component of multi-agent chemotherapy for the treatment of pediatric acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LLy). Hypersensitivity to the PEGylated form, pegaspargase, is the most common toxicity observed and is ideally addressed by substituting multiple doses of erwinia asparaginase for each subsequent dose of pegaspargase. An international shortage of erwinia asparaginase has limited the therapeutic options for those experiencing pegaspargase hypersensitivity. Here, we report pegaspargase can be safely administered, while maintaining sustained levels of asparaginase activity, to patients who have had a prior hypersensitivity reaction to pegaspargase by using a standard rapid desensitization protocol. Ten patients with prior hypersensitivity reactions to pegaspargase were treated by using a standardized rapid desensitization protocol. Eight patients had therapeutic asparaginase levels between days 4 and 7 of ≥0.05 IU/mL, and seven patients continued to have sustained levels above ≥0.1 IU/mL between days 10 and 14. Based on chemotherapy regimens, five of these patients successfully received more than one dose of pegaspargase utilizing this protocol.
