Observed to expected lung area to head circumference ratio (O/E LHR) in fetuses with congenital anomalies of the kidney and urinary tract (CAKUT): assessment and evaluation as predictive factor for acute postnatal outcome-a single center study.

Introduction: To assess the observed to expected lung area to head circumference ratio (O/E LHR) in fetuses with congenital anomalies of the kidney and urinary tract (CAKUT) and to explore its value as a potential predictive factor for postnatal outcome. Methods: A retrospective single-center study was conducted on pregnancies complicated by CAKUT between 2007 and 2018. The lung-to-head ratio (LHR) was calculated for each fetus by two independent observers. Correlations between O/E LHR and various perinatal outcome factors were assessed with Spearman's rank correlation. Furthermore, nominal logistic regression was performed to assess O/E LHR as predictive factor for respiratory distress in newborn. Results: Of 64 pregnancies complicated by CAKUT, 23 were terminated. In the 41 cases of continuation of pregnancy, newborn presenting respiratory distress with need for respiratory support in the delivery room showed earlier gestational age at onset of amniotic fluid abnormalities and at birth. Although median O/E LHR and median single deepest pocket (SDP) of amniotic fluid were significantly smaller in newborn that did develop respiratory distress with need of respiratory support in the delivery room, neither O/E LHR nor SDP were accurate predictors for the development of respiratory distress. Conclusions: Our data show that O/E LHR alone cannot serve as a predictive marker for fetal outcome in pregnancies complicated by CAKUT, though it might still be a helpful parameter together with detailed renal ultrasound evaluation, onset of amniotic fluid abnormality and SDP, particularly in its extreme values.

Effect of 3α-dihydroprogesterone and 5α-dihydroprogesterone on DCIS cells and possible impact for postmenopausal women.

OBJECTIVE: Progesterone metabolites 5α-dihydroprogesterone (5αP) and 3α-dihydroprogesterone (3αP) have opposite effects on proliferation, apoptosis and metastasis in the breast. Evidence regarding their influence on ductal carcinoma in situ (DCIS) lesions is lacking. METHODS: MCF10DCIS.com cells were cultured in a 3D culture system and treated with 5αP or 3αP. After 5 and 12 days of treatment, polymerase chain reaction (PCR) of proliferation, invasion/metastasis, anti-apoptotic or other markers was performed. Cells treated with the tumor-promoting 5αP were observed under the light and confocal microscopes to reveal possible morphological changes that could indicate a transition from an in situ to an invasive phenotype. As a control, the morphology of the MDA-MB-231 invasive cell line was examined. The invasive potential after exposure to 5αP was also assessed using a detachment assay. RESULTS: The PCR analysis of the chosen markers showed no statistically significant difference between naive cells and cells treated with 5αP or 3αP. DCIS spheroids retained their in situ morphology after treatment with 5αP. The detachment assay showed no increased potential for invasion after exposure to 5αP. Progesterone metabolites 5αP and 3αP do not facilitate or prohibit tumor promotion/invasion in MCF10DCIS.com cells, respectively. CONCLUSION: As oral micronized progesterone has been proved effective for hot flushes in postmenopausal women, first in vitro data propose that progesterone-only therapy could possibly be considered for women after DCIS suffering from hot flushes.

Diagnosis of endometriosis in the 21st century.

Endometriosis is a common disease but, due to the wide spectrum of symptoms, diagnosis can be delayed 8-12 years. Laparoscopy is nowadays the gold standard for diagnosis. A less invasive method could shorten the time to diagnosis. The aim of this review is to systematically summarize the literature regarding possible less invasive methods for the diagnosis of endometriosis. Electronic databases, including MEDLINE/PubMed, Cochrane, and Google Scholar, were searched to identify relevant studies; 53 publications contributed to this review. Low invasive tests including imaging, genetic tests, biomarkers, or miRNAs could be the key for establishing a less invasive diagnosis of endometriosis. The findings generally support that different methods can differently contribute to the diagnosis, also depending on the type of endometriosis. For example, transvaginal ultrasound has a sensitivity of 93% and a specificity of 96% in the diagnosis of endometrioma, while superficial/peritoneal endometriosis cannot be detected with imaging processes. Although several non-invasive tests including imaging, genetic tests, biomarkers, or miRNAs show promising diagnostic potential, further research is required before they can be recommended in routine clinical care. The combination of low invasive tests may be the solution to a reliable low invasive diagnosis of endometriosis.
