[PMID: 38350238 DOI: 10.1016/j.bios.2024.116062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 01/12/2024] [Accepted: 01/22/2024] [Indexed: 02/15/2024]
Abstract
Detecting biomarkers in biofluids directly without sample treatments makes molecular diagnostics faster and more efficient. Aptasensors, the nucleic acid-based molecular biosensors, can detect a wide range of target molecules, but their susceptibility to degradation and aggregation by nucleases and charged proteins, respectively, limits their direct use in clinical samples. In this work, we demonstrate that when aptasensors are encapsulated in proteinosomes, the protein-based liposome mimics, clinically important small molecules can be sensitively and selectively detected in non-treated specimens, such as 100 % unpurified serum. As serum albumin is used to form the membrane, the nanomeshed proteinosomes become semi-permeable and antifouling, which enables exclusive admission of small molecules while blocking unwanted large proteins. Consequently, the enclosed aptasensors can maintain close-to-optimal performance for target binding, and nucleolytic degradation and electrostatic aggregation are effectively suppressed. Three different structure-switching aptamers specific for estradiol, dopamine, and cocaine, respectively, are demonstrated to fully conserve their high affinities and specificities inside the microcapsules. The shielding effect of proteinosomes is indeed exceptional; the enclosed DNA aptasensors remain completely intact over 18 h in serum and even in an extremely concentrated DNase solution (1 mg/ml, ∼300,000× the serum level). Moreover, the proteinosome-mediated compartmentalization enables independent operation of multiple aptasensors in the same mixture. Hence, simultaneous real-time sensing of two different targets is demonstrated with different operation modes, 'recording' target appearance and 'reporting' target concentration changes. This work is the first demonstration of small-molecule-specific aptasensors operating with optimal performance in serum environments and will find promising applications in molecular diagnostics.

Abstract
OBJECTIVE We aimed to assess whether ovulation induction treatments affect obstetric and neonatal outcomes. STUDY DESIGN This was a historic cohort study of deliveries in a single university-affiliated medical center between November 2008 and January 2020. We included women who had one pregnancy following ovulation induction and one unassisted pregnancy. The obstetric and perinatal outcomes were compared between pregnancies following ovulation induction and unassisted pregnancies, so that each woman served as her own control. The primary outcome measure was birth weight. RESULTS A total of 193 deliveries following ovulation induction and 193 deliveries after unassisted conception by the same women were compared. Ovulation induction pregnancies were characterized by a significantly younger maternal age and a higher rate of nulliparity (62.7 vs. 8.3%, p < 0.001). In pregnancies achieved by ovulation induction, we found a higher rate of preterm birth (8.3 vs. 4.1%, p = 0.02) and instrumental deliveries (8.8 vs. 2.1%, p = 0.005), while cesarean delivery rates were higher following unassisted pregnancies. Birth weight was significantly lower in ovulation induction pregnancies (3,167 ± 436 vs. 3,251 ± 460 g, p = 0.009), although the rate of small for gestational age neonates was similar between the groups. On multivariate analysis, birth weight remained significantly associated with ovulation induction after adjustment for confounders, while preterm birth did not. CONCLUSION Pregnancies following ovulation induction treatments are associated with lower birth weight. This may be related to an altered placentation process following uterine exposure to supraphysiological hormonal levels. KEY POINTS · Ovulation induction entails lower birthweight.. · This may relate to supraphysiological hormonal levels.. · Monitoring fetal growth is advised in such cases..

Abstract
RESEARCH QUESTION Does programmed frozen embryo transfer (FET) with high-dose oestrogen affect obstetric outcomes and placental findings? DESIGN A retrospective cohort of live singleton deliveries at a single institution between 2009 and 2017, including deliveries attained by IVF with programmed FET; oocyte recipients were excluded. High-dose oestrogen was defined as a daily dose >6 mg throughout treatment. All placentas were evaluated regardless of complication status and the Amsterdam classification was used to analyse findings. RESULTS A total of 57 deliveries in the high-dose oestrogen group were compared with 274 controls. The high-dose oestrogen group displayed significantly longer duration of oestrogen treatment (18.8 ± 4.9 versus 13.3 ± 2.7 days, P < 0.001), total cumulative oestrogen dose (149.7 ± 46.1 versus 80.3 ± 16.8 mg, P < 0.001) and lower endometrial thickness (8.5 ± 1.4 versus 9.8 ± 1.7 mm, P < 0.001). After adjustment for confounders, higher dose oestrogen was found to be associated with a lower average birthweight (coefficient -252.4 g, 95% confidence interval [CI] -483.5 to -21.2), a higher rate of low-birthweight neonates (adjusted odds ratio [aOR] 4.88, 95% CI 1.05 to 22.57), bilobated placentas (aOR 3.36, 95% CI 1.04 to 10.89), accessory lobes (aOR 8.74, 95% CI 1.24 to 61.5), accelerated villous maturation (aOR 2.06, 95% CI 1.09 to 3.87), retroplacental haematoma (aOR 5.39, 95% CI 1.11 to 26.13) and maternal malperfusion lesions (aOR 1.46, 95% CI 1.04 to 2.05). CONCLUSION A higher daily oestrogen dose in programmed FET is associated with low birthweight and placental changes, although this may relate to altered endometrial properties and not to the treatment itself.

The follicular-phase depot GnRH agonist protocol results in a higher live birth rate without discernible differences in luteal function and child health versus the daily mid-luteal GnRH agonist protocol: a single-centre, retrospective, propensity score matched cohort study. Reprod Biol Endocrinol 2022; 20:140. [PMID: 36123706 PMCID: PMC9483542 DOI: 10.1186/s12958-022-01014-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 09/10/2022] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND The gonadotropin-releasing hormone agonist (GnRH-a) has been used in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles for a long time. This paper evaluates the efficacy and safety of two commonly used protocols (follicular-phase depot GnRH-a protocol and daily mid-luteal long GnRH-a protocol) in normal responders undergoing IVF/ICSI using propensity score matching (PSM) analysis. METHODS A total of 6,816 infertile women treated within the period from January 2016 to September 2020 were stratified into cohorts. A total of 2,851 patients received the long-acting group (depot GnRH-a protocol), and 1,193 used the short-acting group (long GnRH-a protocol) after the data-selection process. PSM was utilized for sampling by up to 1:1 nearest neighbour matching to adjust the numerical difference and balance the confounders between groups. The primary outcome was the live birth rate (LBR). Multivariable logistic analysis was used to evaluate the difference between these two protocols in relation to the LBR. RESULT(S) In this study, 1:1 propensity score matching was performed to create a perfect match of 964 patients in each group. After matching, the blastocyst formation rates, oestradiol (E2) value on Day hCG + 9, progesterone (P) value on Day hCG + 9, implantation rates, clinical pregnancy rates, and LBR were more favourable in the depot GnRH-a protocol than in the long GnRH-a protocol (P < 0.05). However, the moderate or severe OHSS rates were higher in the depot group than in the long group (P < 0.001). There were no significant differences in endometrial thickness, luteal support medication, early pregnancy loss rates, mid- and late-term pregnancy loss rates, or foetal malformation rates between the two protocols. CONCLUSION(S) Compared with the daily short-acting GnRH agonist protocol, the follicular-phase depot GnRH-a protocol might improve LBRs in normogonadotropic women without discernible differences in luteal function and child health.

Abstract
Background We aimed to assess the correlation between ovarian hyperstimulation syndrome (OHSS) in the early course of in vitro fertilization (IVF) pregnancies and obstetric outcomes. Methods We identified records of patients admitted due to OHSS following IVF treatment at our institution between 2008 and 2020. Cases were included if pregnancy resulted in a live singleton delivery (OHSS group). OHSS cases were matched at a 1:5:5 ratio with live singleton deliveries following IVF with fresh embryo transfer (fresh transfer group) and frozen embryo transfer (FET group), according to maternal age and parity. Computerized files were reviewed, and maternal, obstetric and neonatal outcomes compared. Results Overall, 44 OHSS cases were matched with 220 fresh transfer and 220 FET pregnancies. Patient demographics were similar between the groups, including body mass index, smoking and comorbidities. Gestational age at delivery, the rate of preterm births, preeclampsia and cesarean delivery were similar between the groups. Placental abruption occurred in 6.8% of OHSS pregnancies, 1.4% of fresh transfer pregnancies and 0.9% of FET pregnancies (p=0.02). On post-hoc analysis, the rate of placental abruption was significantly higher in OHSS pregnancies, compared with the two other groups, and this maintained significance after adjustment for confounders. Birthweights were 3017 ± 483, 3057 ± 545 and 3213 ± 542 grams in the OHSS, fresh transfer and FET groups, respectively (p=0.004), although the rate of small for gestational age neonates was similar between the groups. Conclusions OHSS in the early course of IVF pregnancies is associated with an increased risk of placental abruption.

Gonadotropin Stimulation Reduces the Implantation and Live Birth Rate but Not the Miscarriage Rate of Embryos Transferred When Compared to Unstimulated In Vitro Fertilization. Reprod Sci 2022; 30:283-290. [PMID: 35768691 PMCID: PMC9810560 DOI: 10.1007/s43032-022-01016-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Accepted: 06/14/2022] [Indexed: 01/07/2023]
Abstract
Research suggests that gonadotropin stimulation in in vitro fertilization (IVF) treatment affects embryo quality and the endometrium that might influence embryo implantation, placentation and establishment of a viable pregnancy. We assessed the impact of gonadotropin stimulation on implantation, live birth and miscarriage rates per transferred embryo by comparing stimulated and unstimulated IVF treatment. In a cohort of 728 couples, 1310 IVF cycles with successful embryo transfer were analysed; 857 cycles were stimulated with gonadotropins > 75 IU/day (333 poor responder < 4 oocytes; 524 normal responders), and 453 were unstimulated. In total, 1913 fresh cleavage-stage embryos were transferred. Zygote but no embryo selection was performed, and supernumerous zygotes were vitrified. The implantation rate was defined as number of sonographically detected amniotic sacs; live birth rate as number of children born per transferred embryo. Modified mixed effect Poisson regression was used to account for the dependency of cycles and embryos within the same women and the same transfer cycle. Adjustments were made for maternal age, parity, primary or secondary infertility and indication for IVF. Per transferred embryo, implantation rates (rate ratio (RR) 1.37; 95% CI 1.04-1.81; p = 0.028; aRR 1.42; 95% CI 1.10-1.84; p = 0.008) and live birth rates (RR 1.33; 95% CI 0.95-1.86; p = 0.093; aRR 1.38; 95% CI 1.01-1.88; p = 0.044) were higher in NC-IVF compared to cIVF normal responders. Miscarriage did not differ (RR 0.99; 95% CI 0.59-1.65; p = 0.965; aRR 0.90; 95% CI 0.52-1.53 p = 0.698). Similar results were obtained in poor responders. The study suggests an impact of gonadotropin stimulation on the implantation potential of embryos.

[PMID: 34934981 PMCID: PMC8655429 DOI: 10.1016/j.xfre.2021.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 05/13/2021] [Accepted: 05/17/2021] [Indexed: 11/28/2022] Open
Abstract
Objective To evaluate the association between infertility treatments and small for gestational age (SGA) births. Design Cross-sectional study. Setting United States, 2015–2019. Patient(s) Women (n = 16,836,228) who delivered nonmalformed, singleton live births (24–44 weeks’ gestation). Intervention(s) Any infertility treatment, including assisted reproductive technology (ART) and prescribed fertility-enhancing medications. Main Outcome Measure(s) Small for gestational age birth, defined as sex-specific birth weight <10% for gestational age. Associations between SGA and infertility treatment were derived from Poisson regression with robust variance. Risk ratios (RR) and 95% confidence intervals (CI) were derived after adjusting for confounders. In a sensitivity analysis, we corrected for nondifferential exposure misclassification and unmeasured confounding biases. Result(s) Subsequently, 1.4% (n = 231,177) of pregnancies resulted from infertility treatments (0.8% ART and 0.6% fertility-enhancing medications). Of these, SGA births occurred in 9.4% (n = 21,771) and 11.9% (n = 1,755,925) of pregnancies conceived with infertility treatment and naturally conceived pregnancies, respectively (adjusted RR, 1.07; 95% CI, 1.06, 1.08). However, after correction for misclassification bias and unmeasured confounding, infertility treatment was associated with a 27% reduced risk of SGA (bias-corrected RR, 0.73; 95% CI, 0.53, 0.85). Similar trends were seen for analyses stratified by exposure to ART and fertility-enhancing medications, as well as for SGA <5th and <3rd percentiles. Conclusion(s) Exposure to infertility treatment is associated with a reduced risk of SGA births. These findings, which are contrary to some published reports, may reflect changes in the modern practice of infertility care, maternal lifestyle, and compliance with prenatal care within the infertile population. Until these findings are corroborated, the associations must be cautiously interpreted.

Abstract
Aim Breastfeeding has numerous advantages. Our aim was to investigate whether breastfeeding initiation and duration in women with pregnancies conceived through in vitro fertilisation differ from spontaneously conceived pregnancies. Methods This is a comparative cross‐sectional study about breastfeeding behaviour performed at the Bern University Hospital including mothers of singletons conceived by in vitro fertilisation (n = 198) with or without gonadotropin stimulation between 2010 and 2016 (in vitro fertilisation group). They were compared to a population‐based control group (n = 1421) of a randomly selected sample of mothers in Switzerland who delivered in 2014. Results A total of 1619 women were included in this analysis. Breastfeeding initiation rates were high, similar between the in vitro fertilisation group (93.4%) and the control group (94.8%). No increased risk of stopping breastfeeding earlier after in vitro fertilisation treatment compared to the control group could be found over the observational period of 12 months (HR = 1.00, 95% CI 0.83‐1.20, P = .984). There was no difference in breastfeeding initiation or duration after gonadotropin‐stimulated vs unstimulated in vitro fertilisation. Conclusion In Switzerland, in vitro fertilisation treatments were not associated with earlier breastfeeding cessation. This result is reassuring for mothers undergoing in vitro fertilisation.

The greater incidence of small-for-gestational-age newborns after gonadotropin-stimulated in vitro fertilization with a supraphysiological estradiol level on ovulation trigger day. Acta Obstet Gynecol Scand 2019; 98:1575-1584. [PMID: 31338840 PMCID: PMC6899753 DOI: 10.1111/aogs.13691] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 05/29/2019] [Accepted: 07/07/2019] [Indexed: 12/27/2022]
Abstract
Introduction Reproductive scientists have postulated various risk factors for lower birthweight following conventional gonadotropin‐stimulated in vitro fertilization compared with spontaneously conceived children: parental factors (age, health, duration of subfertility and smoking habits); ovarian stimulation; laboratory procedures; the number of oocytes retrieved and the number of embryos transferred. Our aim was to investigate the impact of gonadotropin stimulation and serum estradiol level on the risk of a newborn being small‐for‐gestational‐age. Material and methods We conducted a cohort study (2010‐2016) of singletons (n = 155) born either after conventional gonadotropin‐stimulated in vitro fertilization (using ≥150 IU/d human gonadotropin for stimulation) or after natural cycle in vitro fertilization without any stimulation. We analyzed perinatal outcomes using birthweight percentiles, adjusted for gestational age and sex. Results The proportion of small‐for‐gestational‐age was 11.8% following conventional gonadotropin‐stimulated in vitro fertilization and 2.9% after natural cycle in vitro fertilization (P = 0.058). The odds of small‐for‐gestational‐age were significantly higher with supraphysiological estradiol levels in maternal serum on ovulation trigger day (unadjusted odds ratio 4.58; 95% confidence interval 1.35‐15.55; P = 0.015). It remained significant after adjusting for maternal height, age and body mass index (adjusted odds ratio 3.83; 95% confidence interval 1.06‐13.82; P = 0.041). Conclusions We found an associated risk of children being born small‐for‐gestational‐age after conventional gonadotropin‐stimulated in vitro fertilization compared with natural cycle in vitro fertilization. This higher risk is significantly associated with supraphysiological estradiol levels. We propose a reduction in the dosage of gonadotropin to minimize the risk of small‐for‐gestational‐age and future health consequences.
