Molecular analysis of circulating tumor DNA from breast cancer patients before and after surgery and following adjuvant chemotherapy.

The primary aim of the present study is to provide a complex molecular profile of tumors using liquid biopsy and to monitor profile changes over time in association with surgery and administered adjuvant therapy. Our secondary aim was to compare the liquid biopsy profile with the tissue biopsy and assess concordance. A total of 27 samples of circulating tumor DNA (ctDNA) collected from 9 breast cancer patients at three different time points and their matched formalin-fixed and paraffin-embedded (FFPE) samples of primary tumor were analyzed with targeted next-generation sequencing.

New York Transplant Teams Versus COVID-19.

New York State, and especially New York City, were hit hard by the coronavirus disease 2019 (COVID-19) virus. While we followed its course in other parts of the world, and began preparations, there was no way we could have been prepared for the volume and severity of illness that began to overflow in our emergency departments and hospital units. We expanded intensive care units into our medical surgical units while turning conference rooms into medical surgical patient care areas.

Comparison of Somatic Mutation Profiles Between Formalin-Fixed Paraffin Embedded Tissues and Plasma Cell-Free DNA from Ovarian Cancer Patients Before and After Surgery.

Ovarian carcinogenesis can be induced by a large number of somatic gene mutations. Circulating tumor DNA (ctDNA) released into peripheral blood can provide insights into the genomic landscape of cancer cells and monitor their dynamics. Our aim was to detect and compare the genetic profiles in tumor tissue and plasma before and after tumor resection in ovarian cancer patients.

How to Handle Arterial Conduits in Liver Transplantation? Evidence From the First Multicenter Risk Analysis.

Objective: The aims of the present study were to identify independent risk factors for conduit occlusion, compare outcomes of different AC placement sites, and investigate whether postoperative platelet antiaggregation is protective.

Background: Arterial conduits (AC) in liver transplantation (LT) offer an effective rescue option when regular arterial graft revascularization is not feasible. However, the role of the conduit placement site and postoperative antiaggregation is insufficiently answered in the literature.

Breast Cancer in Young Women: Status Quo and Advanced Disease Management by a Predictive, Preventive, and Personalized Approach.

Why does healthcare of breast cancer (BC) patients, especially in a young population, matter and why are innovative strategies by predictive, preventive, and personalized medicine (PPPM) strongly recommended to replace current reactive medical approach in BC management? Permanent increase in annual numbers of new BC cases with particularly quick growth of premenopausal BC patients, an absence of clearly described risk factors for those patients, as well as established screening tools and programs represent important reasons to focus on BC in young women. Moreover, "young" BC cases are frequently "asymptomatic", difficult to diagnose, and to treat effectively on time. The objective of this article is to update the knowledge on BC in young females, its unique molecular signature, newest concepts in diagnostics and therapy, and to highlight the concepts of predictive, preventive, and personalized medicine with a well-acknowledged potential to advance the overall disease management.

Association of single nucleotide polymorphisms in FGF-RAS/MAP signalling cascade with breast cancer susceptibility.

The fibroblast growth factor receptors (FGFRs) and Ras/mitogen activated protein (RAS/MAP) signalling cascades are the main molecular pathways involved in breast carcinogenesis. This study aims to determine the association between FGF10 (rs4415084 C>T), FGFR2 (rs2981582 C>T) and MAP3K1 (rs889312 A>C) gene polymorphisms and breast cancer, to analyse the discriminative ability of each SNP and to test the accuracy of the predictive breast cancer risk model which includes all SNPs. We conducted a case-control study of 170 women (57.

Tobacco Use is a Modifiable Risk Factor for Post-Transplant Biliary Complications.

Purpose: Biliary complications following liver transplantation are a significant source of morbidity, potentially leading to graft failure necessitating retransplantation. We sought to evaluate smoking as an independent risk factor for post-transplant biliary complications.

Methods: The clinical course of all adult primary deceased donor liver transplants at our center from 1992 to 2012 was reviewed.

Impact of gene methylation on the metastatic axillary nodal status in breast cancer patients.

Hypermethylation of CpG islands is a hallmark of cancer and occurs at an early stage in breast tumorigenesis. To gain insight into the epigenetic switches that may promote and/or contribute to the initial neoplastic events during breast carcinogenesis, the present study focused on the DNA methylation profile of invasive breast carcinoma. The aim of the study was to evaluate the prognostic significance of Ras association domain family 1 isoform A () promoter methylation status in operable breast cancer, and to analyze the utility of this biomarker regarding its association with metastatic and nonmetastatic axillary nodal status.

Methylation in promoter regions of PITX2 and RASSF1A genes in association with clinicopathological features in breast cancer patients.

Breast cancer is a heterogeneous disease with very different responses to therapy and different length of survival. In many cases, however, the determination of the stage and histopathological characteristics of breast cancer is insufficient to predict prognosis and response to treatment for the vast heterogeneity of the disease. To understand the molecular signature of subtypes of breast cancer, we attempted to identify the methylation status of key tumour suppressor gene Ras association (RalGDS/AF-6) domain family member 1 isoform a (RASSF1A) and a member of the paired-like homeodomain transcription factor family which functions in left-right asymmetry development (PITX2) and to correlate results with known clinicopathological features of breast cancer.

Orai1 protein expression and the role of calcium release-activated calcium channels in the contraction of human term-pregnant and non-pregnant myometrium.

Aim: This experimental in vitro study examined differences in the expression and activity of calcium release-activated calcium (CRAC) channels of human term-pregnant and non-pregnant myometrium.

Material And Methods: The tissue samples were obtained from term-pregnant myometrium in labor of women undergoing cesarean section and from non-pregnant myometrium of women undergoing total hysterectomy due to uterine myoma. The expression of Orai1 protein, a pore-forming subunit of CRAC channels, in human myometrium was examined using immunohistochemistry.

TNF α G308A gene polymorphism has an impact on renal function, microvascular permeability, organ involvement and severity of preeclampsia.

Background/aims: Preeclampsia (PE) is a life-threatening complication of pregnancy that is associated with a high rate of maternal and perinatal morbidity and/or mortality worldwide. If untreated, it can progress to eclampsia, which can result in the death of the mother, the fetus or both. The etiology of PE is still uncertain; however, recently the role of the immune system has gained in importance.

Recurrent secondary postpartum hemorrhages due to placental site vessel subinvolution and local uterine tissue coagulopathy.

Background: Postpartum hemorrhage (PPH) represents a serious problem for women and obstetricians. Because of its association with hemorrhagic shock and predisposition to disseminated coagulopathy, it is a leading cause of maternal deaths worldwide. Furthermore, the jeopardy of PPH is rising with the secondary form of PPH occurring between 24 hours and 6 weeks postpartum, when women are already discharged home.

Impact of fetal pulse oximetry and ST analysis surveillance withdrawal on rates of obstetric surgery and frequency of low birth umbilical artery pH: a cause of rising caesarean rates?

A retrospective observational study on a sample of 13,413 deliveries analysed the effect of a withdrawal of the CTG additional diagnostic methods of fetal hypoxia (fetal pulse oximetry and ST analysis of the fetal ECG) on operative delivery rates and frequency of the umbilical arterial pH < 7.15. Following the withdrawal, obstetricians are more likely to perform caesarean sections for fetal hypoxia (OR 2.

Participation of BKCa2+ and KATP potassium ion channels in the contractility of human term pregnant myometrium in in vitro conditions.

Aim: The aim of this study was to assess the participation of ligand-sensitive potassium large conductance calcium-activated ion channels (BK(Ca2+) ) and adenosine triphosphate (ATP)-sensitive potassium ion channels (K(ATP) ) using its openers (NS1619 and pinacidil) in the contractility of human term pregnant myometrium in in vitro conditions.

Methods: Human myometrium tissue samples were collected from term pregnant laboring women who had to undergo cesarean section. The contractility of myometrium was induced by the application of oxytocin into the organ bath.

Physiological changes in blood flow velocities in the superior mesenteric and coeliac artery in healthy term fetuses and newborns during perinatal period.

Objective: The aim was to describe the course of physiological changes in coeliac artery (CA) and superior mesenteric artery (SMA) blood flow velocities (BFVs) during the perinatal period in healthy term fetuses and infants as it has not been studied in detail so far.

Methods: This prospective Doppler ultrasound study included 50 infants. The examinations were performed in a fetus after the completion of 36.

Application of uterotonics on the basis of regular ultrasonic evaluation of the uterus prevents unnecessary surgical intervention in the postpartum period.

Objective: Ultrasonographic evaluation of the postpartum uterus to prevent retained placental tissue complications is still a matter of debate, and it is difficult to interpret its necessity on the basis of previous studies. We hypothesized that the application of uterotonics on the basis of regular postpartum ultrasound scanning of the uterus may reduce the number of unnecessary curettages in a large unselected population.

Methods: This was a cross-sectional observational study conducted among mothers (n = 6,028) delivering at two different (secondary and tertiary) hospitals to analyze the benefit of postpartum uterine ultrasound for clinical implications.

Anti-apoptotic and pro-apoptotic gene expression evaluated from eutopic endometrium in the proliferative phase of the menstrual cycle among women with endometriosis and healthy controls.

Objective: Endometriosis affects 5-15% of women in the general population and 40% of women seeking infertility evaluation. Its etiology and pathogenesis is controversial. Abnormalities of genes involved in the regulation of apoptosis have been thought to play a role in origin.
