Ethnicity is an independent predictor of IVF-ICSI outcome: a study of 5,549 cycles in Spain and India.

AIM: To determine the role of ethnicity on IVF/ICSI outcomes between Indian and white Caucasian women. SETTINGS AND DESIGN: Retrospective cohort study. MATERIALS AND METHODS: White Caucasian and Indian women undergoing IVF/ICSI treatment cycles. Total 5549 self, non-donor, fresh IVF cycles conducted from January 2014 to March 2015, out of which, 4227 were white Caucasian and 1322 were Indian. Data were collected on baseline characteristics, IVF cycle parameters and outcomes. Ongoing pregnancy rate (OPR) was measured as main outcome. RESULTS: Indian women differed significantly from white Caucasian women in baseline characteristics like age (30.6 ± 0.2 versus 37.6 ± 0.1 years; p < 0.001), BMI (22.3 ± 0.2 versus 26.6 ± 1.0 kg/m2; p < 0.05), duration of infertility (6.9 ± 3.0 versus 2.5 ± 0.1 years; p < 0.001) and antral follicle count (AFC) (8.9 ± 0.4 versus 7.5 ± 0.2; p < 0.001). Indian women had lower implantation rate (30.1% versus 39.6%: p < 0.001) and OPR (35.1% versus 41.7%: p < 0.001) compared with white Caucasian women. Regression analysis proved independent effect of ethnicity on OPR (OR 0.944; 95% CI 0.928-0.961: p < 0.001) Conclusions: OPR was significantly lower among Indian ethnic group following IVF/ICSI suggest that ethnicity, like age, is a major and an independent predictor of IVF outcome.

Personalized Embryo Transfer Helps in Improving In vitro Fertilization/ICSI Outcomes in Patients with Recurrent Implantation Failure.

AIMS: This study aims to compare clinical outcomes in patients of recurrent implantation failure (RIF), who had embryo transfer (ET) following a receptive (R) endometrial receptivity array (ERA) and a personalized embryo transfer (pET) after a nonreceptive (NR) ERA. SETTINGS AND DESIGN: This was a retrospective observational study. STUDY PERIOD: July 2013-September 2017. SUBJECTS AND METHODS: Two hundred and forty-eight patients having unexplained RIF who underwent ERA test were included in the study. Clinical outcomes were compared between patients having a receptive (R) ERA and those having a NR ERA who underwent a pET-based on ERA. STATISTICAL ANALYSIS USED: Chi-square and t-test. RESULTS: ERA predicted receptive (R) endometrium at P + 5 in 82.3% (204/248) patients and NR in 17.7% (44/248) patients. Average failed previous in vitro fertilization cycles were 3.67 ± 1.67 among receptive ERA patients and 4.09 ± 1.68 among NR ERA patients. Pregnancy rate (PR), clinical PR, implantation rate (IR), abortion rate (AR), ongoing pregnancy rate (OPR), and cumulative PR were comparable between patients having receptive ERA who had a routine Embryo Transfer (ET) and those with an NR ERA who underwent a pET. CONCLUSIONS: ERA is helpful in identifying the window of implantation (WOI) through genetic expressions of the endometrium to pinpoint embryo transfer timing. pET guided by ERA in patients of RIF with displaced WOI improves IRs and OPRs.

One Plus One Is Better Than Two: Cumulative Reproductive Outcomes Are Better after Two Elective Single Blastocyst Embryo Transfers Compared to One Double Blastocyst Embryo Transfer.

AIMS: The aim of this study is to compare cumulative in vitro fertilization-intracytoplasmic sperm injection outcomes following two elective single embryo transfer (eSET) versus one double embryo transfer (DET) using blastocyst(s). SETTINGS AND DESIGN: This was retrospective observational study. STUDY PERIOD: The study was conducted during January 2015-December 2015. SUBJECTS AND METHODS: Forty-one fresh + 25 frozen eSET versus 123 DET using self-oocytes and 68 fresh + 35 frozen eSET versus 184 DET using donor-oocytes were included in the study. All failing to achieve live birth after first eSET underwent frozen embryo transfer cycle with second blastocyst. Cumulative outcome after two eSET were compared with one DET. STATISTICAL ANALYSIS USED: The analysis was performed by Chi-square and t-test. RESULTS: In self-oocytes group, higher but statistically nonsignificant cumulative clinical pregnancy rate (CPR) (58.5% vs. 57.7%, P = 0.92) and live birth rate (LBR) (48.7% vs. 44.7%, P = 0.65) with significantly lower multiple pregnancy rate (MPR) (4.2% vs. 45%, P = 0.0002) were obtained; whereas in donor-oocytes group, comparable cumulative CPR (73.5% vs. 65.7%, P = 0.24), significantly higher LBR (64.7% vs. 48.9%, P = 0.02) and significantly lower MPR (4% vs. 51.2%, P = 0.00005) were obtained after two eSET vs. one DET. In self-oocytes group, the incidence of prematurity (10% vs. 21.4%, P > 0.05) and low birth weight (25% vs. 45.6%, P > 0.05) were lower but statistically nonsignificant, whereas in donor-oocytes group, incidence of prematurity was lower but statistically nonsignificant (26.7% vs. 38.8%, P > 0.05) while of low birth weight was significantly lower (32.7% vs. 51.2%, P = 0.0038) after two eSET versus one DET. CONCLUSION: Cumulative LBR was higher with lower incidence of multiple births, prematurity and low birth weight after two eSET versus one DET using self- or donor-oocytes. Higher use of eSET improves reproductive outcomes in patients with good prognosis.

Pseudomonas aeruginosa and Serratia marcescens contamination associated with a manufacturing defect in bronchoscopes.

BACKGROUND: Several outbreaks and pseudo-outbreaks of Pseudomonas aeruginosa and Serratia marcescens infections associated with bronchoscopy have been reported. We conducted an investigation of P. aeruginosa and S. marcescens isolates related to bronchoscopy at a community hospital. METHODS: We reviewed the records of all bronchoscopic procedures at the community hospital from July to October 2001. Environmental samples were obtained. Pulsed-field gel electrophoresis (PFGE) was performed on isolates of P. aeruginosa. RESULTS: From July 1 to October 31, 2001, 66 bronchoscopic procedures were performed in 60 patients, and 43 specimens were obtained for bacterial culture; 20 of the specimens (47 percent) were positive for P. aeruginosa. Six (30 percent) of the specimens that were positive for P. aeruginosa also yielded S. marcescens. All 20 P. aeruginosa isolates were associated with procedures performed with three of four new bronchoscopes from the same manufacturer. Contrary to manufacturing specifications, the biopsy-port caps on all four bronchoscopes were easily removable, and P. aeruginosa was cultured from the biopsy ports of the three implicated bronchoscopes. The PFGE patterns of P. aeruginosa isolates from the bronchoscopes, patients, and two environmental samples were indistinguishable. One patient was hospitalized with P. aeruginosa pneumonia 11 days after bronchoscopy. The manufacturer reported a design change instituted in 1997, and production problems may have resulted in the distribution of bronchoscopes that did not meet specifications. CONCLUSIONS: We documented contamination of bronchoscopes with P. aeruginosa and S. marcescens and possible infection of patients at a community hospital as a result of the inadequate disinfection of bronchoscopes because of a manufacturing defect.
