RESUMEN

Background: The postpartum period is a time of unmet contraceptive need for many women. Home visits by a health care worker during pregnancy or after delivery could increase postpartum contraceptive use and decrease barriers to accessing postpartum care. This study investigated the association between prenatal or postpartum home visits and postpartum contraceptive use using a large sample of U.S. women from 41 states. Subjects and Methods: We conducted a cross-sectional analysis using weighted survey data from the 2012-2015 Phase 7 Pregnancy Risk Assessment and Monitoring Systems Core and Standard Questionnaires. Descriptive statistics and multivariate logistic regression models estimated the association between having a prenatal or postpartum home visit and self-reported postpartum contraceptive use. Results: Of 141,296 women, approximately 21% received prenatal or postpartum home visits and 79% used postpartum contraception. After controlling for sociodemographic, reproductive, and health-related factors, women who received prenatal or postpartum home visits had a higher odds of postpartum contraception use (adjusted odds ratio 1.08, 95% confidence interval 1.02-1.15, p = 0.009). Women who were older, were minority race, had less than a high school education, received inadequate prenatal care, experienced partner abuse during pregnancy, or experienced multiple stressors during pregnancy had a lower odds of postpartum contraception use in adjusted analyses controlling for home visitation. Conclusion: Given the benefits of recommended interpregnancy intervals to both the mother and the baby, adding formal contraceptive counseling and offering a variety of postpartum contraceptive methods in the home could further strengthen home visitation programs in the United States and may support women in achieving their reproductive goals.

RESUMEN

OBJECTIVE: To examine the degree to which paternal variables of age, body mass index (BMI), and sperm parameters affect vitrified donor oocyte IVF outcomes. Previous studies examining the impact of male partner characteristics on in-vitro fertilization (IVF) have found conflicting results. Concerns are rising over the potential effects of paternal factors, such as age and obesity, on pregnancy and child health. Frozen donor oocyte IVF offers an ideal model to study these effects. DESIGN: Retrospective chart review. SETTING: Private fertility clinic. PATIENT(S): Nine hundred forty-nine recipients undergoing transfer of blastocyst embryo(s) from a vitrified oocyte donor bank between 2008-2015. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Implantation rate, clinical pregnancy rate, live birth rate, rate of low birth weight singleton infants (≤2500 g), and preterm deliveries (PTD) of singleton infants (<37 wk). RESULTS: After adjusting for covariates known to affect oocyte donation cycle success, male age, BMI and sperm parameters were not associated with differences in IVF outcomes. There were higher PTD rates for men ≥51 years and BMI ≥35 kg/m2, however, these were not significant after adjustment. There were no differences in rates of low birth weight infants with men >35 years or BMI >25 kg/m2. Lastly, there were no differences in rates of PTD or low birth weight infants with abnormal sperm parameters. CONCLUSIONS: Neither advancing male age, elevated BMI, nor poor sperm quality were associated with outcomes in frozen donor oocyte IVF cycles in this study. Intracytoplamic sperm injection and "oocyte quality" likely mitigate some of the effects of male variables on outcomes following cryopreserved oocyte donation.

RESUMEN

PURPOSE: This study aimed to determine the current percentage of United States (U.S.) assisted reproductive technology (ART) clinics offering sex selection via pre-implantation genetic screening (PGS) for non-medical purposes. METHODS: The authors conducted website review and telephone interview survey of 493 U.S. ART clinics performing in vitro fertilization (IVF) in 2017. Main outcome measures were pre-implantation genetic screening (PGS)/pre-implantation genetic diagnosis (PGD) practices and non-medical sex selection practices including family balancing. RESULTS: Of the 493 ART clinics in the USA, 482 clinics (97.8%) responded to our telephone interview survey. Among all U.S. ART clinics, 91.9% (n = 449) reported offering PGS and/or PGD. Furthermore, 476 clinics responded to survey questions about sex selection practices. Of those ART clinics, 72.7% (n = 346) reported offering sex selection. More specifically among those clinics offering sex selection, 93.6% (n = 324) reported performing sex selection for family balancing, and 81.2% (n = 281) reported performing for elective purposes (patient preference, regardless of rationale for the request). For couples without infertility, 83.5% (n = 289) of clinics offer sex selection for family balancing and 74.6% (n = 258) for non-specific elective reasons. CONCLUSIONS: The majority of U.S. ART clinics offer non-medical sex selection, a percentage that has increased substantially since last reported in 2006.

RESUMEN

Two cases of devastating fetal malformations associated with vanished monochorionic twins were identified upon review of pathology files. A 35-year-old G1P0 woman and 36-year-old G3P1 woman were both diagnosed with an intrauterine twin gestation via transvaginal ultrasound at 10 weeks. The spectrum of fetal anomalies ranged from omphalocele, bilateral upper extremity, and unilateral lower extremity hypoplasia, to craniofacial malformation with diaphragmatic hernia. On histopathologic examination, the placentas demonstrated vascular anastomoses between the surviving co-twin and the "vanished" fetal sac. We propose anastomotic placental vasculature as a contributing factor to the observed fetal malformations. Additionally, genetic or teratogenic factors may have been attributed to the demise of the first twin and the anomalies seen in the other twin. While such instances are rare, they are important to consider when counseling patients regarding outcomes associated with a monochorionic vanished twin.

RESUMEN

We describe two occurrences of nontrophoblastic mesenchymal tumors of the placenta. The first placental tumor was found along the placental margin, and the second was identified close to the insertion of the fetal membranes along the placental disc. Microscopically both lesions demonstrated bland fibroblastic cells with intricate vasculature and inflammatory cells. Both lesions were negative for estrogen receptor (ER), progesterone receptor (PR), beta-HCG, PLAP, CD34, desmin, h-caldesmin, and smooth muscle actin by immunohistochemistry. Some cells were weakly positive for CD10, a nonspecific finding. The morphologic and immunohistochemical characteristics of these lesions were most consistent with nodular fasciitis, a tumor most commonly found in the soft tissues. FISH positive for USP6 gene rearrangement in our two patients confirmed the molecular similarity of these lesions to nodular fasciitis of soft tissue. Such lesions can be easily dismissed on gross placental examination as infarcts or thrombi, thus these rare entities are likely underreported.

RESUMEN

Malakoplakia, a rare granulomatous disease caused by impaired macrophage response, has been reported only rarely in children. We report 3 unique cases, with lesions occurring in unusual locations in children with primary immune deficiencies.
