The Role of Wnt/Beta-Catenin Pathway, SATB1 and SATB2 in Endometrial Cancer Patients

Wnt/β-catenin signaling pathway plays an established role in various diseases and is considered a hallmark of endometrial cancer (EC). Special AT-rich sequence-binding protein 1 and 2 (SATB1 and SATB2) are nuclear matrix-associated proteins involved in chromatin remodeling and regulation of gene expression. SATB1 promotes the progression of numerous types of cancers, whereas SATB2 acts as a tumor suppressor. Despite a recent progress in our knowledge about EC, the exact mechanisms that control their proliferation and metastatic potential still remain unknown. The aim of our study was to investigate the association between Wnt3A, β-catenin, SATB1 and SATB2 protein level and the clinicopathological features of EC patients. 92 EC patients, aged 37-84, were enrolled to our study. The immunoexpression of WNT3A was found in specimens from all EC patients, β-catenin was expressed in 97% of the cases, SATB1 in 87%. The significant association between Wnt3a expression and tumor grade was found; moreover mean IRS for Wnt3a turned out to be significantly lower in high-grade tumors than in low-grade malignancies (p=0.038). In turn, immunoexpression of β-catenin varied significantly across FIGO stages and was associated with the presence of lymph node metastases. Mean IRS for β-catenin in patients with lymph node metastases was significantly lower than in those without (p = 0.028). The Kaplan-Meier analyses demonstrated a stepwise impairment of cancer overall survival with increasing SATB1 expression. In conclusion, both Wnt/β-catenin signaling pathway and SATB1 contribute to progression of EC. Downregulation of β-catenin may predispose to lymphatic spread of EC. In turn, downregulation of Wnt3a seems to be characteristic for high-grade tumors, but probably does not play a role in formation of lymph node metastases. The important role of SATB1 as a predictor of poor survival and could be helpful in establishing a more accurate prognosis in endometrial cancer patients.

PCOS: A Chronic Disease that Fails to Produce Adequately Specialized Pro-Resolving Lipid Mediators (SPMs)

Introduction: Polycystic Ovary Syndrome (PCOS) is an endocrinologic disorder that affects 5-15 % of women of their reproductive age and is a frequent cause of infertility. Major symptoms include hyperandrogenism, ovulatory dysfunction, a characteristic multi-follicular morphology of the ovary, an elevated ratio of LH/FSH, and often obesity and/or insulin resistance. PCOS also represents a state of chronic low-grade inflammation that is closely interlinked with the metabolic features. Inflammatory processes consist of the acute inflammatory response and resolution processes initiated concomitantly. "Classical" pro-inflammatory lipid mediators like prostaglandins (PG), leukotrienes (LT), or thromboxanes (TX) are derived from arachidonic acid (AA) and are crucial for the initial response. Resolution processes are driven by four families of so-called specialized pro-resolving mediators (SPMs): resolvins, maresins, lipoxins, and protectins. SPM biosynthesis starts from the essential polyunsaturated fatty acids DHA, DPA, or EPA via certain hydroxylated intermediates (18-HEPE, 17-HDHA, 14-HDHA). The present study aimed to establish lipid mediator profiles of PCOS patients compared to healthy women to identify differences in their resolutive and pro-inflammatory lipid parameters. Material and Methods: Blood samples were taken (20 ml), separated into plasma and serum, and analyzed by HPLC/MS-QQQ. Fifteen female patients (18-45 years) were diagnosed with PCOS according to Rotterdam criteria, and five healthy women, as comparator group, were recruited for the study. The main outcome measures were: Pro-inflammatory lipid mediators (PG, LT, TX) and their precursor AA; SPMs (Resolvins, Maresins, Protectins, Lipoxins), their precursors EPA, DHA, DPA, and their active biosynthesis pathway intermediates (18-HEPE, 17-HDHA, 14-HDHA). Ratio [(sum of pro-inflammatory molecules)/sum of SPMs]. Results: The level of pro-inflammatory parameters in serum was significantly higher in PCOS-affected women. The ratio [(sum of pro-inflammatory molecules) / (sum of SPMs plus hydroxylated intermediates)] reflecting the inflammatory state was significantly lower in the group of healthy women. Conclusion: There is a strong pro-inflammatory state in PCOS patients. Further research will clarify whether supplementation with SPMs or their precursors may improve this state.

BACKGROUND Krukenberg tumor is a rare metastatic tumor of the ovary with characteristic histopathological features known as signet-ring cells. It usually presents in women around 45 years of age, however, we present an uncommon case in a 38-year-old pregnant woman. We report this case because of the unusual findings, the uncommon presentation in this younger age bracket, its diagnostic challenge, and poor prognosis. CASE PRESENTATION We describe an unusual case of a young woman with a history of painful vaginal bleeding at 13 weeks of pregnancy and treated for abruptio placentae. In her routine prenatal visit at week 20 of pregnancy, she was found to have a uterine fundus greater than her gestational age and referred to the hospital to discard polyhydramnios. At her admission a pelvic ultrasound was performed with normal findings of a 25 weeks pregnancy, also showing bilateral enlarged ovaries with heterogeneous echogenicity. The MRI showed a left tumoral lesion with dimensions of 22.1 x 13.6 x 16.3 cm, with lobulated regular contours with displacement of peripheral structures and mild compression of the bladder, the left ureter, and the inferior vena cava. The lesion was heterogeneous with irregular borders. The patient was programmed for a cesarean section; during the operation, the abdominal cavity showed bilateral tumors compatible with MRI findings, the ovarian tumors were sent to pathology and the results showed poorly differentiated mucinous adenocarcinoma (WHO III) with extensive signet-ring cells, an indicative of Krukenberg tumor. CONCLUSION: The case presented is rare due to its presentation in a pregnant woman without identifiable risk factors for gastric cancer. The incidental finding suggests the pregnancy masked the clinical presentation of gastric cancer, and the rapid deterioration of the patient is consistent with the aggressiveness described in the literature. The limited descriptions of this neoplasm in our country and the torpid evolution of this case highlight the importance of further studies of this cancer in Mexico.

Hyperandrogenism and insulin resistance are co-pathologies of polycystic ovary syndrome (PCOS). Recent evidence has suggested that elevated local cortisol levels are associated with ovarian and endometrial insulin resistance in hyperandrogenic PCOS patients, but the molecular mechanisms underlying these clinical findings remain unclear. We and others have used chronic treatment with human chorionic gonadotropin (hCG) and insulin to create an in vivo rodent model for the onset and development of PCOS-like phenotypes. Here, we aimed to determine whether the molecular mechanisms of glucocorticoid receptor (GR) signaling, mitochondrial function, and local inflammation in the ovary and uterus are intrinsically different in PCOS-like rats compared to controls. In both the ovary and the uterus, decreased expression of two GR protein isoforms was concurrent with increased expression of Fkbp51 but not Fkbp52 mRNA in PCOS-like rats compared to controls. However, PCOS-like rats exhibited an opposite regulation of Hsd11b1 or Hsd11b2 mRNAs in the two tissues. Further, the expression of several oxidative phosphorylation-related protein components was decreased in the PCOS-like ovary and uterus, but surprisingly the expression of many genes involved in mitochondrial function and homeostasis was increased in the same tissues and animals. Additionally, PCOS-like rats showed the increased expression of ovarian and uterine NFκB signaling proteins and Tnfaip3 mRNA. In PCOS-like rats, while similar decreased expression of Il1b, Il6, and Mmp2 mRNAs was seen in the ovary and uterus, the opposite regulation of Tnfa, Ccl2, Ccl5, and Mmp3 mRNA expression was observed in the two tissues. Both ovaries and uteri from PCOS-like animals showed increased collagen deposition compared to controls. Collectively, our observations suggest that hyperandrogenism and insulin resistance disrupt ovarian and uterine GR activation and trigger compensatory or adaptive effects for mitochondrial homeostasis, allowing tissue-level maintenance of mitochondrial function in order to limit ovarian and uterine dysfunction. Our study also suggests that hyperandrogenism and insulin resistance-induced activation of NFκB signaling resulting in aberrant regulation of inflammation-related gene expression might be tissue specific in female reproductive tissues.

Background: As noninvasive prenatal screening usage grows in the general obstetrics setting, proper patient education on the screen’s benefits and limitations is needed. Objective: Describe the use of a technology platform designed for large-scale dissemination of noninvasive prenatal screening information and results. Study Design: The technology platform functioned as follows: Patients were emailed a link to an noninvasive prenatal screening general-education video upon laboratory receipt of a test requisition. Providers were then notified upon availability of patients’ results. If noninvasive prenatal screening results were negative, the patient was sent an automated email with instructions to access results through a secure portal where she could watch tailored informational videos, request “on-demand” or scheduled genetic counseling, or decline any further services. If genetic counseling was elected, a summary of the session was sent to the ordering provider and patient upon completion. If noninvasive prenatal screening results were positive, either the ordering provider or a board-certified genetic counselor contacted the patient directly to communicate test results and provide counseling. The number and type of results issued through the platform, the number and type of genetic counseling consultations completed, and factors associated with requesting laboratory-delivered genetic counseling were tracked and analyzed for a 39-month period. Results: Over the study period, 67,122 noninvasive prenatal screening results were issued through the platform, and 4,673 patients elected genetic counseling consultations; 95.2% (n=4,450) of consultations were for patients receiving negative results. Over 70% (n= 3,370) of consultations were on-demand rather than scheduled. Median consultation time was 14 minutes for positive results and six minutes for negative results. A positive screen, advanced maternal age, family history, previous history of a pregnancy with a chromosomal abnormality, and other high-risk pregnancy were associated with the greatest odds of electing laboratory-delivered genetic counseling. Conclusions: By combining web education, automated notifications, and genetic counseling, we implemented a service that effectively facilitates results disclosure for ordering providers. These data demonstrate the capability to deliver noninvasive prenatal screening results, education, and counseling—congruent with management guidelines—to a large population, which is imperative to quality care as uptake increases.

Background: Maternal near-miss refers to a situation where a woman who nearly died but survived from severe life-threatening obstetric complications that occurred during pregnancy, childbirth or within 42 days of termination of pregnancy. It has been estimated that up to 9 million women survive obstetric complications every year. According to studies done around the world most mothers suffer from Near Miss due to the factors which includes, low socioeconomic status, patient related, health provider related, and health related and health institution related issues. Objectives: The objective of the study was to determine the proportion of maternal near misses and its associated factors in Selected Public Health Institutions of Keffa, Bench-Maji and Sheka Zones of South Nations Nationalities and Peoples Regional state, South West Ethiopia, 2017. Methodology: Hospital based cross-sectional study design was employed and simple random sampling techniques (Lottery Method) was used to select the study institution and Systematic sampling technique was used to select 845 study participants every 5^th interval. Information was collected by using pre-tested and structured interviewer administered questioner. Using SPSS version 21 software, descriptive statistics and bivariate logistic regression analysis was done and variables with p-value <0.2 were transferred to multivariate analysis and during Multivariate logistic regression analysis Variables with P-value < 0.05 were considered as statistically significant and AOR with 95% CI were used to control for possible confounders and to interpret the result. The results were summarized by tables, graphs and charts. Result: There were 5530 Live Births, 227 Sever Acute Maternal Morbidity cases of this 210 were Maternal Near-Misses cases and 17 were maternal deaths, 364 Maternal Near-Misses Events. The overall Maternal Near-Misses Proportion is 24.85%. The maternal Near-Misses outcome ratio was 41 cases/1,000 live births (LB); mortality ratio was 12.35cases/1 maternal death and 74.8/1000LB of mortality index. Parity, residence, distance of living place from hospital, ANC Follow up, duration of labor, and administrative related problems were found to have statistically significant associations. Conclusion: The proportion of Maternal Near-Misses is relatively high when compared to other regional studies and efforts should be done to lower the near-misses.
