Notes

Temporal variability throughout quantitative individual intestine microbiome information and also significance for medical analysis.
To investigate whether deoxyribonucleic acid (DNA) methylation at birth and in childhood differ by conception using assisted reproductive technologies (ART) or ovulation induction compared with those in children conceived without fertility treatment.

Upstate KIDS is a matched exposure cohort which oversampled on newborns conceived by treatment.

New York State (excluding New York City).

This analysis included 855 newborns and 152 children at approximately 9 years of age.

None.

DNA methylation levels were measured using the Illumina EPIC platform. Single CpG and regional analyses at imprinting genes were conducted.

Compared to no fertility treatment, ART was associated with lower mean DNA methylation levels at birth in 11 CpGs (located in/near SYCE1, SPRN, KIAA2013, MYO1D, GET1/WRB-SH4BGR, IGF1R, SORD, NECAB3/ACTL10, and GET1) and higher mean methylation level in 1 CpG (KLK4; all false discovery rate P<.05). The strongest association (cg17676129) was located at SYCE1, which codes for a synaptonemal complex that plays a role in meiosis and therefore infertility. This CpG remained associated with newborn hypomethylation when the analysis was limited to those conceived with ICSI, but this may be because of underlying male infertility. In addition, nine regions in maternally imprinted genes (IGF1R, PPIEL, SVOPL GNAS, L3MBTL, BLCAP, HYMAI/PLAGL1, SNU13, and MEST) were observed to have decreased mean DNA methylation levels among newborns conceived by ART. In childhood, hypomethylation of the maternally imprinted gene, GNAS, persisted. No CpGs or regions were associated with ovulation induction.

ART but not ovulation induction was associated with hypomethylation at birth, but only one difference at an imprinting region appeared to persist in childhood.

To evaluate the association, if any, between serum antimüllerian hormone (AMH) levels and probability of clinical pregnancy and spontaneous abortion (SAB) in the infertility setting.

Retrospective cohort study.

Academic fertility center.

A total of 1,861 gonadotropin stimulation/intrauterine insemination cycles stratified by AMH levels into 3 groups Low, <25th percentile (<0.7 ng/mL); Middle, ≥25th and <75th percentile (0.7-4.4 ng/mL); and High, ≥75th percentile (≥4.5 ng/mL).

Intrauterine insemination after stimulation with gonadotropins.

Cumulative probability of clinical pregnancy over a maximum of 3 and/or 6 cycles and SAB incidence risk rate (IRR). The Kaplan-Meier failure function (log rank test), Cox proportional hazards models, and multilevel mixed-effects Poisson regression models were performed to compare outcomes among the AMH groups.

Overall, in both unadjusted and adjusted models, the probability of achieving a clinical pregnancy was higher in the Middle and High AMH groups pregnancy. A possible negative impact, independent of age, on the risk of SAB was also suggested.Cryopreservation of ovarian tissue to preserve the fertility of girls and young women at high risk of sterility is now widely practiced. Pieces of cryopreserved ovarian cortex can be thawed and autografted to restore fertility, but because of the risks of reintroduction of the cancer, transplantation may not be possible for girls and women with blood-borne leukemias or cancers with a high risk of ovarian metastasis. Cryopreserved ovarian tissue contains mainly primordial follicles but also provides access to immature oocytes from small antral follicles, which may be matured in vitro to provide an additional source of mature oocytes. this website So in cases in which transplantation is contraindicated, fertility restoration could be safely achieved in the laboratory either by in vitro maturation (IVM) of oocytes aspirated from growing follicles or by the complete in vitro growth (IVG) and maturation (IVM) of primordial follicles to produce fertile metaphase II (MII) oocytes. The development of IVM and IVG methods to support all stages of oocytes available within ovarian tissue will maximize the potential for all patients undergoing fertility preservation.The prevalence and ease of electronic communication, specifically email through patient portals associated with electronic medical records or via traditional enterprise email clients (e.g., Outlook) and video, have resulted in increased use for rapid communication between practitioners and their patients. Concerns regarding patient privacy and compliance with the regulations of the Health Insurance Portability and Accountability Act (HIPAA) remain a barrier to routine incorporation of electronic communication into practice. Furthermore, capital investment, implementation, and maintenance costs may provide additional barriers. These long-standing concerns have been heightened and tested by the COVID-19 pandemic. Best-practice guidelines for the secure and safe use of electronic communication with reproductive care patients are provided.Demand for fertility preservation in women for oncologic, nononcologic, and personal reasons has increased dramatically. Meeting that demand is a major challenge, and we are rising to the challenge. Mature oocyte cryopreservation after ovarian stimulation and ovarian tissue cryopreservation are both methods endorsed by the American Society for Reproductive Medicine (formerly The American Fertility Society), and numerous papers confirmed their efficacy. In girls and women with leukemia or cancers who are at a high risk of ovarian metastasis and who may not be eligible for ovarian tissue transplantation, restoration of fertility can only be achieved by in vitro methods. Male fertility preservation has also become a pressing issue and is extensively reviewed in the present journal issue.
To determine whether fertility treatments impact the risk of breast cancer in Jewish Israeli BRCA1/2 mutation carriers.

Historical cohort study.

University-affiliated tertiary medical center.

A total of 1,824 Jewish Israeli BRCA1/2 mutation carriers from a single center were stratified into 1,492 (81.8%) carriers who were not treated for infertility and 332 (18.2%) carriers who underwent fertility treatment with clomiphene citrate (n = 134), gonadotropin (n = 119), invitro fertilization (n = 183), or a combination of treatments (n = 89).

None.

Hazard ratios (HR) and 95% confidence intervals (CI) for the association of breast cancer with fertility treatment and other hormonal and reproductive variables.

Breast cancer was diagnosed in 687 BRCA1/2 mutation carriers. Multivariate analysis, either of the whole group or stratified by each gene, showed no association between fertility treatment and breast cancer risk, regardless of the type of treatment (clomiphene citrate HR 0.77, 95% CI 0.49-1.19; gonadotropin HR 0.
