The novel COVID-19 pandemic has placed medical triage decision-making in the spotlight. As life-saving ventilators become scarce, clinicians are being forced to allocate scarce resources in even the wealthiest countries. The pervasiveness of air travel and high rate of transmission has caused this pandemic to spread swiftly throughout the world. Ethical triage decisions are commonly based on the utilitarian approach of maximising total benefits and life expectancy. We present triage guidelines from Italy, USA and the UK as well as the Jewish ethical prospective on medical triage. The Jewish tradition also recognises the utilitarian approach but there is disagreement between the rabbis whether human discretion has any role in the allocation of scarce resources and triage decision-making.
Objective
To identify baseline characteristics of women with unexplained infertility to determine whether treatment with an aromatase inhibitor will result in a lower rate of multiple gestations than current standard ovulation induction medications.
Design
Randomized, prospective clinical trial
Patients
900 couples with unexplained infertility Interventions: Ovarian stimulation with gonadotropins, clomiphene citrate, or letrozole in conjunction with intrauterine insemination.
Setting
Multicenter University based clinical practices.
Main Outcome Measures
Demographic, laboratory, imaging, and survey characteristics.
Interventions
Collection of baseline demographics, blood samples, and ultrasonographic assessments.
Results
Demographic characteristics of women receiving clomiphene citrate, letrozole, or gonadotropins for ovarian stimulation were very consistent. Their mean age was 32.2 ± 4.4 years and infertility duration was 34.7± 25.7 months, with 59% primary infertility. More than 1/3 of the women were current or past smokers. The mean BMI was 27 and mean AMH level was 2.6; only 11 women (1.3%) had antral follicle counts of less than 5. Similar observations were identified for hormonal profiles, ultrasound characterization of the ovaries, semen parameters, and quality of life assessments in both male and female partners.
Conclusion
The cause of infertility in the couples recruited to this treatment trial is elusive, as the women were regularly ovulating and had evidence of good ovarian reserve both by basal FSH, AMH levels, and antral follicle counts; the male partners had normal semen parameters. The three treatment subgroups have common baseline characteristics, thereby providing comparable patient populations for testing the hypothesis that use of letrozole for ovarian stimulation can reduce the rates of multiples from that observed with gonadotropin and clomiphene citrate treatment.
The current COVID-19 pandemic has raised many questions and dilemmas for modern day ethicists and healthcare providers. Are physicians, nurses and other healthcare workers morally obligated to put themselves in harm’s way and treat patients during a pandemic, occurring a great risk to themselves, their families and potentially to other patients? The issue was relevant during the 1918 influenza epidemic and more recently severe acute respiratory syndrome epidemic in 2003. Since the risk to the healthcare workers was great, there was tension between the ethical duty and responsibility to treat and the risk to one’s own life. This tension was further noted during the 2014 Ebola outbreak in West Africa that left hundreds of healthcare workers dead. The AMA Code of Ethics states that physicians are to ‘provide urgent medical care during disasters…even in the face of greater than usual risk to physicians’ own safety, health or life.’1 Classic Jewish sources have dealt with this question as well. There is an obligation ‘to not stand by idly when your friends life is in danger’; however, the question arises as to whether there are limits to this obligation? Is one required to risk one’s own life to save another’s? There is a consensus that one is not required but the question open to debate is whether it is praiseworthy to do so. However, regarding healthcare workers, there is agreement for ethical, professional and societal reasons that they are required to put themselves in harm’s way to care for their patients.
The increase in the rate of unscheduled cesarean deliveries after a catastrophic neonatal outcome may result in short-term changes in obstetricians' risk evaluation.
Background
Physiological selection of spermatozoa for ICSI (PICSI) is a sperm selection method based on sperm binding to hyaluronic acid. Previous studies on the effect of hyaluronic acid binding assays on fertilization and embryo quality have shown inconsistent results. Previous sibling oocyte studies have not found a significant improvement in fertilization or embryo development with hyaluronic acid binding assays.
Objective
To compare fertilization and embryo development between standard intracytoplasmic sperm injection (ICSI) and PICSI in sibling oocytes.
Materials and Methods
This is a retrospective analysis of all in vitro fertilization (IVF) cycles between January 2017 and April 2020 in which sibling oocytes were randomly fertilized by both ICSI and PICSI. Fertilization rate and the rate of embryos eligible for transfer were compared.
Results
Forty‐five IVF cycles, in which 257 oocytes were fertilized with PICSI and 294 with standard ICSI, were compared. Most of the patients included in the study had previous failures of fertilization, poor embryonic development, implantation failure, or miscarriage. All but two of the patients had at least one previous unsuccessful IVF cycle. Both fertilization rates (71% vs. 83%) and transfer eligible embryo rates (38% vs. 51%) were significantly higher in PICSI fertilized oocytes (p = 0.008 and p = 0.01 respectively).
Discussion
Our study is the largest sibling oocyte study comparing ICSI and PICSI, and the first to find a significant improvement in fertilization and embryo quality with PICSI using sibling oocytes. The fact our cohort included almost exclusively couples with previous unsuccessful IVF cycles might suggest that PICSI should be used in selected cases.
Conclusion
PICSI improves fertilization rates and transfer eligible embryo rates in sibling oocytes in a selected study group.
