    GnRH agonist triggering affects the kinetics of embryo development: a comparative study
    (2016) Gurbuz, Ali Sami; Gode, Funda; Uzman, Mehmet Sukru; Ince, Betul; Kaya, Melek; Ozcimen, Necati; Ozcimen, Emel Ebru; Acar, Ali; 27059823
    Background: To evaluate the effects of an ovulation triggering agent, human chorionic gonadotropin (hCG), versus a gonadotropin-releasing hormone agonist (GnRHa) on early embryo development in vitro using a time-lapse system. Methods: Retrospective analysis of a prospectively collected database. A total of 739 embryos from 152 infertile couples undergoing intracytoplasmic sperm injection cycles. Interventions : Embryo culture in a time-lapse incubator (EmbryoScope, Vitrolife, Goteborg, Sweden). Main Outcome Measures: Embryo morphokinetic parameters. Results: In the 152 women, 252 embryos were derived from GnRHa-triggered cycles compared with 487 embryos derived from hCG-triggered cycles. Time-lapse analysis revealed that embryos from cycles triggered by a GnRHa cleaved faster than embryos derived from hCG-triggered cycles. Conclusion: Triggering with a GnRHa in in vitro fertilization cycles affects embryo kinetics.

    Objective: We aimed to investigate the vaccination status and the risk factors for the intensive care unit (ICU) support need of the laboratory -confirmed breakthrough COVID-19 infection inpatients. Materials and Methods: This multi -center point -prevalence study was conducted on inpatients, divided into two groups as 'fully' and 'partially' vaccinated according to COVID-19 vaccination status. Results: Totally 516 patients were included in the study. The median age was 65 (55-77), and 53.5% (n=276) of the patients were male. Hypertension (41.9%, n=216), diabetes mellitus (DM) (31.8%, n=164), and coronary artery disease (CAD) (16.3%, n=84) were the predominant comorbidities. Patients were divided into two groups ICU (n=196) and non -ICU (n=301). Hypertension (p=0.026), DM (p=0.048), and congestive heart failure (CHF) (p=0.005) were significantly higher in ICU patients and the median age was younger among non -ICU patients (p=0.033). Of patients, 16.9% (n=87) were fully vaccinated, and this group's need for ICU support was statistically significantly lower (p=0.021). Conclusion: We conclude that older age, hypertension, DM, CHF, and being partially vaccinated were associated with the need for ICU support. Therefore, all countries should continuously monitor post -vaccination breakthrough COVID-19 infections to determine the national booster vaccine administration approach that will provide vulnerable individuals the highest protection.
