Longitudinal Study of Pelvic Floor Characteristics Before, During, and After Pregnancy in Nulliparous Women.

OBJECTIVES: To investigate the changes in the pelvic floor before, during, and after pregnancy in the same collective of nulliparous women. METHODS: In a prospective observational pilot study between April 2015 and June 2019 in nulliparous women with planned pregnancy, we used the pelvic organ prolapse quantification (POP-Q) system; a 2-dimensional (2D) sonography to investigate the bladder neck, cervix, and anorectal junction positions; and a 3D/4D sonography to measure the hiatus of the levator ani muscle (LH area) during Valsalva maneuver. Five visits were planned: 1 before, 3 during, and 1 visit after pregnancy. RESULTS: Twenty-four women participated in the study. We achieved a minimum of 2 visit measurements from 10 women who became pregnant. The LH area decreased during the first trimester and then increased until the third trimester. Postpartum, the LH area reached the prepregnancy state. We observed changes in the bladder neck mobility, bladder neck position, cervix, and anorectal junction from the first trimester. Postpartum, the bladder neck mobility was higher, and the position of the bladder neck and anorectal junction was lower than before pregnancy. We observed no remarkable changes in the POP-Q state during pregnancy. CONCLUSION: This was the first study to investigate pelvic floor characteristics in the same collective before, during, and after pregnancy. We observed pelvic floor changes from the prepregnancy state to the first trimester to postpartum. The study results need to be confirmed in a larger study.

Effect of Low-Dose Aspirin on Soluble FMS-Like Tyrosine Kinase 1/Placental Growth Factor (sFlt-1/PlGF Ratio) in Pregnancies at High Risk for the Development of Preeclampsia.

BACKGROUND: Soluble FMS-like Tyrosine Kinase 1 (sFlt-1) and placental growth factor (PlGF) have been reported to be highly predictive several weeks before the onset of preeclampsia. OBJECTIVE: To investigate longitudinal changes of serum levels sFlt-1 and PlGF in pregnant women at high risk for the development of preeclampsia and to reveal an impact of aspirin on maternal serum concentrations of sFlt-1 and PlGF. METHODS: This was a prospective longitudinal study in 394 women with various risk factors for the development of preeclampsia (chronic hypertension, antiphospholipid syndrome/APS or systemic lupus erythematosus/SLE, thrombophilia, women with a history of preeclampsia, pathologic first trimester screening for preeclampsia) and 68 healthy women. Serum levels of sFlt-1 and PlGF were measured prospectively at 4-week intervals (from gestational weeks 12 until postpartum). RESULTS: The sFlt-1/PlGF ratio was significantly higher in women with an adverse obstetric outcome compared to women with a normal pregnancy, starting between 20 and 24 weeks of gestation. There was no effect of aspirin on sFlt-1/PlGF ratio in women with chronic hypertension, APS/SLE, thrombophilia and controls. The use of aspirin showed a trend towards an improvement of the sFlt-1/PlGF ratio in women with preeclampsia in a previous pregnancy and a significant effect on the sFlt-1/PlGF ratio in women with a pathologic first trimester screening for preeclampsia. CONCLUSIONS: Our findings reveal an impact of aspirin on sFlt-1/PlGF ratio in women with a pathologic first trimester screening for preeclampsia, strongly supporting its prophylactic use.

Does third trimester cervical length predict duration of first stage of labor?

OBJECTIVE: To examine the association between third trimester cervical length (CL) measurement and duration of the first stage of labor. METHODS: This prospective cohort study included women with a singleton pregnancy who had routine CL measurements taken by transvaginal ultrasonography between 37 and 39 weeks gestation. Subjective duration of the first stage of labor was defined as the duration of contractions that the women subjectively had from the onset of regular contractions to full effacement of the cervix. Objective duration of first stage of labor was defined as 3 cm cervical dilation independent of cervical effacement until full effacement of the cervix. Associations between variables were analyzed using nonparametric correlations coefficients. A model relating the duration of labor to predictors was built using linear regression. RESULTS: In this analysis a total of 129 women were included. There was no significant correlation between CL and subjective duration of labor (ρ = -0.037, p = 0.695); however, a reduction in CL increased the objective duration of the first stage of labor (ρ = -0.269, p = 0.013). In univariate analysis parity (p = 0.018), hypertensive disorders (p = 0.013) and induction of labor (p = 0.022) were significantly associated with subjective duration of the first stage of labor. CONCLUSION: A long cervix in the third trimester is not associated with a prolonged first stage of labor. Induction of labor and multiparity were associated with a shorter first stage of labor while hypertension was associated with a longer duration of labor.

A rare case of cancer-to-cancer metastasis: breast cancer to renal cell cancer : Case report and review of literature.

BACKGROUND: Cancer-to-cancer metastasis is very rare with less than 50 cases described in literature. This article reports a case of breast cancer with synchronous metastasis to clear cell renal cell cancer. CASE DESCRIPTION: A 79-year-old woman was diagnosed with a bilateral breast carcinoma. Sonographic staging investigation of the abdomen revealed a 6 cm wide expansion of the right kidney. Bilateral mastectomy and nephrectomy of the right kidney was performed. The histology revealed a clear cell renal cell carcinoma and in the center of the tumor a 0.5 cm metastasis of the breast cancer. The patient's comorbidities and performance status precluded chemotherapy und she received palliative radiotherapy, targeted monoclonal antibody therapy and antihormonal treatment. CONCLUSIONS: Even if cancer-to-cancer metastasis is a very rare phenomenon, the simultaneous or consecutive finding of a renal tumor in women with breast cancer should be carefully evaluated.

Comparison of two-risk assessment algorithms for preeclampsia in first trimester with consecutive intake of low-dose aspirin in the high-risk group - an observational study.

We analyzed outcome of women screened for preeclampsia with two different multifactorial risk algorithms (Predictor®Software by PerkinElmer, PerkinElmer, Waltham, MA; PERK-group: n = 214 and Viewpoint® by GE Healthcare, Dornstadt, Germany; VIEW-group: n = 209) in first trimester. Women at high risk for developing preeclampsia were advised to take low-dose acetylsalicylic acid (LDA). Screening positive rates for early onset preeclampsia differed significantly between the two groups (7.9% versus 26.3%; p = 0.000). According the clinical use of screening test criteria, LDA was prescribed in 63 (29.4%) women in the PE-group and 55 (26.3%) in the VP-group (p = 0.516). There were no differences in onset of preeclampsia [4 (1.9%) versus 6 (2.9%); p = 0.540]. No early or severe preeclampsia occurred in the whole population.

Natural outcome of trisomy 13, trisomy 18, and triploidy after prenatal diagnosis.

Trisomy 13, trisomy 18, and triploidy belong to the chromosomal abnormalities which are compatible with life, but which are also associated with a high rate of spontaneous abortion, intrauterine death, and a short life span. This study was conducted to analyze natural outcome after prenatal diagnosis of these disorders. Between January 1, 1999 and December 31, 2009, we investigated all amniocenteses and chorionic villus biopsies carried out at our department. All cases with fetal diagnosis of triploidy, trisomy 13, and 18 were analyzed, with a focus on cases with natural outcome. Overall, 83 (78%) cases of pregnancy termination and 24 (22%) patients with natural outcome (NO) were identified. The NO group included 15 cases of trisomy 18, six cases of triploidy, and three cases of trisomy 13. No case of triploidy was born alive. The live birth rate was 13% for trisomy 18 and 33% for trisomy 13. The three live-born infants with trisomy 13 and 18 died early after a maximum of 87 hr postpartum. Our data are consistent with the literature concerning outcome of triploidy, with none or only a few live births. Analyzes of trisomy 13 and 18 indicate a very short postnatal life span. Different study designs and diverse treatment strategies greatly affect the fetal and neonatal outcome of fetuses with triploidy, trisomy 13, and 18. More studies analyzing natural outcome after prenatal diagnosis of these chromosomal abnormalities are needed. Non-termination of these pregnancies remains an option, and specialists advising parents need accurate data for counseling.
