Abstract
The aim of this systematic review is to investigate the impact of corticotropin-releasing hormone (CRH) family peptides and their corresponding receptors on human physiology and disease onset, with a specific focus on gynaecological malignancies such as breast, endometrial, ovarian, vulvar, and cervical cancer. A comprehensive systematic review of 3 medical databases was conducted by 2 independent reviewers. We reviewed studies that explored the expression and role of CRH peptides in various aspects of cancer biology, in the context of breast, endometrial, ovarian, vulvar, and cervical cancer. Our findings reveal that CRH family peptides and their receptors, CRHR1 and CRHR2, are expressed in diverse gynaecological tissues, including cancer cells. Notably, we observed differential expression patterns among different gynaecological cancer types and stages, indicating potential associations with tumour aggressiveness and patient prognosis. Furthermore, CRH peptides were found to exert significant influences on critical cellular processes, such as cell proliferation, migration, invasion, and immune response, in gynaecological cancers. These findings highlight the multifaceted roles of CRH family peptides in gynaecological malignancies and emphasize the need for further research in this field. Therefore, understanding the mechanisms underlying the involvement of CRH family peptides in tumourigenesis may open new avenues for targeted therapeutic strategies in gynaecological malignancies.

Abstract
Advanced-stage gynaecological cancer represents a clinical entity with challenging surgical treatment in an effort to optimize prognosis. Hyperthermic intraperitoneal chemotherapy (HIPEC) following cytoreductive surgery (CRS) has been reported as a method potentially eligible to improve prognosis. However, no definitive conclusions have yet been made on which types of cancer and which context HIPEC may actually have a beneficial impact. The present review discusses the efficacy and safety of HIPEC as a treatment option for patients with primary/recurrent ovarian, endometrial and cervix cancer, as well as peritoneal sarcomatosis. A literature search was conducted using MeSH terms for each topic in the PubMed database and supplemented with a manual search to retrieve additional articles eligible for inclusion/fulfilling the inclusion criteria. The implementation of HIPEC appears to be beneficial in terms of survival in patients with epithelial ovarian carcinoma (EOC) following neoadjuvant chemotherapy, as well as in patients with recurrent EOC. Statistical superiority is not justified by current studies regarding other gynaecological malignancies with peritoneal dissemination. Furthermore, as regards safety, HIPEC following CRS does not appear to significantly increase the mortality and morbidity rates compared to the use of CRS alone. The rationale for using HIPEC and CRS in the treatment of ovarian cancer, particularly in the neoadjuvant setting, as well as for recurrences, is adequately evidenced, with acceptable safety and post-operative complication rate profiles. Its current place in the multimodal strategy for patients with peritoneal metastases remains uncertain, however. Randomized clinical trials are warranted to further examine the use of HIPEC and establish the optimal regimen and temperature settings. The role of optimal cytoreduction and no residual disease, as well as the proper patient selection remain basic parameters for maximizing survival parameters.

Abstract
AIM To compare the diagnostic parameters of electrical impedance spectroscopy (EIS) via ZedScan, a device that measures spectra to differentiate between normal and abnormal cervical tissues, when used as an adjunct to colposcopies in the diagnosis of HSILs/CIN2+ in Greek women with abnormal referral cytology toward colposcopy alone and HPV mRNA-testing. METHODS This study analyzed 86 women, patients of the Colposcopy and Cervical Pathology Clinic of 2nd Obstetrics and Gynecology Department, Aristotle University of Thessaloniki at Hippokration General Hospital, between January 2022 and September 2022. During the visits, women were subjected to cytology, colposcopy alone and then with EIS/ZedScan and histological sampling. RESULTS Common use of colposcopies and EIS/ZedScan allowed detecting an additional 14 cases of CIN2+ (16.2%) that colposcopy alone failed to report. EIS enhanced the sensitivity of colposcopy from 80.65% to 100% equal with that of HPV-mRNA test while retaining a high specificity (94.74%) which is much higher than specificity of HPV mRNA-testing (65.45%). EIS-assisted colposcopy had the highest value combination of positive and negative predictive values (96.15% and 100%) compared to colposcopy alone (100% and 75%) and HPV mRNA-testing (72.46% and 100%). CONCLUSIONS Colposcopies performed with EIS/ZedScan demonstrated effectiveness in the diagnosing of CIN2+ leading to a significant increase in the number of CIN2+ that would have been missed if only colposcopy was applied especially in women with LSIL referral cytology. EIS/ZedScan seems to possess the ideal diagnostic threshold for sensitivity, specificity, and predictive values for CIN2+ compared to colposcopy alone and HPV mRNA-testing.

Abstract
Although appetite and its disorders have been implicated in disease progression and outcomes, ghrelin concentrations, an objective appetite measure, are rarely assessed in patients with gynecological malignancies. The present study aimed to assess changes in post-operative versus pre-operative appetite levels in patients with gynecological cancers scheduled for tumor removal surgery (N = 53). Acylated ghrelin concentrations were assessed as an objective appetite proxy, whereas the Council of Nutrition appetite questionnaire (CNAQ) was employed as a subjective appetite measure. Ghrelin concentrations were increased post-operatively (median: 12.1 pg/mL, IQR: 0.67 to 23.5, p-value = 0.001) but the perceived appetite of patients (CNAQ) remained unchanged (median: -1, IQR: -3 to 1). Tumor removal surgery decreased all anthropometric indices (body weight, body mass index, waist and hips circumferences, triceps skinfolds, body fat, fat mass and fat mass index, p-value ≤ 0.001 for all) and doubled the risk of malnutrition among patients. No difference was recorded in the change in participants' objective and subjective appetite when they were classified according to the tumor type. No correlation was observed between ghrelin concentrations and CNAQ score pre-operatively (Spearman's rho correlation coefficient = -0.181, p-value = 0.298) or post-operatively (Spearman's rho correlation coefficient = 0.071, p-value = 0.684). The observed post-operative rise in ghrelin concentrations is associated with body weight loss and consists of a possible defense mechanism of the human body, aiming to prolong survival.

Abstract
AIM To evaluate the diagnostic performance of E6/E7 HPV-mRNA overexpression towards HPV-DNA testing and p16/Ki67 immunocytochemistry in a post-op population to verify if this biomarker can be effectively used as indicator of successful cervical intraepithelial neoplasia (CIN) treatment. METHODS Our study retrospectively analyzed 197 patients of our Colposcopy Clinic between January 2013 and September 2020 coming with an abnormal Pap smear suggestive for colposcopy, and after a series of follow-ups including liquid-based cytology (LBC) and punch-biopsy sampling, there were surgically treated. LBC was used for cytology and molecular analysis of the three HPV-related biomarkers. RESULTS Six months after treatment, 93% of the HPV-mRNA-positive women became negative while this applied to only 80.2% of the HPV-DNA-positive women. HPV persistence was 6.9% at 6-12 months after treatment. The comparison among cytology, colposcopy, HPV-DNA test, and HPV-mRNA test after treatment revealed that the last one is the only with a strong correlation with actual severity (histology during treatment) (ρ = 0.345, p = 0.006) implying that clinical cases with more severe CIN may have higher chances of unsuccessful treatment. HPV-mRNA test had higher sensitivity (100%), specificity (96.88%), and positive predictive value (45.45%) for CIN2+ recurrent lesions when compared with HPV-DNA testing (80%, 82.81%, 10.81% respectively) and p16/Ki67 immunocytochemistry (80%, 95.83%, 33.33% respectively) while their negative predictive values were similar. CONCLUSIONS E6/E7 mRNA detection has higher diagnostic values for the prediction of treatment failure compared with HPV-DNA testing and p16/Ki67 immunocytochemistry, and as an outcome could be used as predictive indicator of CIN-treatment status.

Abstract
Our hypothesis was that the predictive accuracy of pathogenic variants in genes participating in the homologous recombination repair (HRR) system in patients with epithelial ovarian cancer (EOC) could be improved by considering additional next-generation sequencing (NGS) metrics. NGS genotyping was performed in tumor tissue, retrospectively and prospectively collected from patients with EOC, diagnosed from 8/1998 to 10/2016. Variants were considered clonal when variant allele frequencies corresponded to >25%. The primary endpoint was overall survival (OS). This study included 501 patients with EOC, predominantly with high-grade serous (75.2%) and advanced stage tumors (81.7%); median age was 58 years (22-84). Pathogenic and clonal pathogenic variants in HRR and/or TP53 genes were identified in 72.8% and 66.5% tumors, respectively. With a median follow-up of 123.9 months, the presence of either pathogenic or clonal pathogenic HRR-only variants was associated with longer OS compared to HRR/TP53 co-mutation (HR=0.54; 95% CI, 0.34-0.87, Wald's p=0.012 and HR=0.45; 95% CI, 0.27-0.78, Wald's p=0.004, respectively). However, only the presence of clonal HRR-only variants was independently associated with improved OS (HR=0.55; 95% CI, 0.32-0.94, p=0.030). Variant clonality and co-occuring TP53 variants affect the predictive value of HRR pathogenic variants for platinum agents in patients with EOC.

Abstract
BACKGROUND/AIM Ovarian cancer (OVCA) is characterized by genomic/molecular intra-patient heterogeneity (IPH). Tissue histology and morphological features are surrogates of the underlying genomic/molecular contexture. We assessed the morphological IPH of OVCA tumor compartments and of lymphocytic infiltrates in multiple matched samples per patient. MATERIALS AND METHODS We examined 294 hematoxylin & eosin (H&E) OVCA tumor whole sections from 70 treatment-naïve patients who had undergone cytoreductive surgery. We assessed morphological subtypes as immunoreactive (IR), solid - proliferative (SD), papilloglandular (PG), and mesenchymal transition (MT); subtype load per patient; stromal tumor-infiltrating lymphocyte (sTIL) density as average per sample; and, as maximal sTIL values (max-TILs) among all samples per patient, ovaries and implants. RESULTS Among all 294 tumor sections, the most frequent primary morphological subtype was PG (n=150, 51.0%), followed by MT (71, 24.1%), SD (48, 16.3%) and IR (15, 5.1%). Subtype combinations were observed in 67/294 sections (22.8%) and IPH in 48/70 patients (68.6%). PG prevailed in ovaries (p<0.001), SD and MT in implants (p=0.023 and p<0.001, respectively). sTILs were higher in SD compared to non-SD (p=0.019) and lower in PG, respectively (p<0.001). sTIL density was higher in implants than in ovaries (p<0.001). Higher max-TILs were associated with stage IV disease (p=0.043), upper abdominal dissemination (p=0.024), endometrioid histology (p=0.013), and grade 3 tumors (p=0.021). Favorable prognosticators were higher max-TILs per patient (PFS, OS) and higher SD-load (PFS). CONCLUSION Clinically relevant morphological and host immune-response IPH appear to be the norm in OVCA. This may complicate efforts to decipher sensitivity of the tumor to certain treatment modalities from a single pre-operative biopsy.

Abstract
BACKGROUND In Greece the population-level impact of HPV vaccination is unknown due to lack of official registries. This study presents in a pragmatic frame the comparison of cervical pathology data between HPV-vaccinated and unvaccinated women referred for colposcopy. PATIENTS AND METHODS This is an observational prospective cohort study performed in 7 academic Obstetrics and Gynaecology Departments across Greece between 2009-2019. Cases were women that had completed HPV vaccination before coitarche and were referred for colposcopy due to abnormal cytology. For each vaccinated woman an unvaccinated matched control was selected. RESULTS A total of 849 women who had been vaccinated before coitarche and 849 unvaccinated controls were recruited. The combination of cytological, colposcopic and molecular findings necessitated treatment in only a single case among vaccinated (0.1%) and in 8.4% among unvaccinated. CONCLUSION HPV vaccination at a proper age can markedly reduce development of severe cervical precancers and consequently the need for treatment, as well as their long-term related obstetrical morbidity.

Abstract
Abstract
Purpose
Transcatheter aortic valve implantation (TAVI) is often followed by conduction abnormalities, leading to a permanent pacemaker implantation (PPI). Data regarding the clinical impact of PPI following TAVI is yet to be established.
Methods
Patients with severe and symptomatic aortic stenosis [effective orifice area (EOA) ≤1cm2] referred for TAVI at our institution were consecutively enrolled. Prospectively collected demographic, laboratory and echocardiographic data were retrospectively analyzed. Patients were stratified into two groups according to the need for PPI after TAVI and were followed up postoperatively with clinical and echocardiographic assessment. Primary clinical endpoint was all-cause mortality, as defined by the criteria proposed by the Valve Academic Research Consortium 2.
Results
In total, 292 patients were included (male: 50.2%, mean age: 80±7.6 years) in our study. Of these, 109 (37.5%) underwent PPI simultaneously or shortly after TAVI. The median follow-up period was 27.3 In this period, all-cause mortality showed no significant difference between patients with and those without PPI after TAVI (log-rank p=0.756), even after excluding patients with a pre-existing pacemaker from the analysis. Subgroup analysis also showed no difference in survival between patients with low ejection fraction (<50%) and those with preserved (≥50%) receiving a permanent pacemaker after TAVR (log-rank p=0.269). Taking into consideration factors that were found to associate to PPI in univariate analysis (pre TAVI - ejection fraction, pulmonary artery systolic pressure and New York Heart Association functional class) in a multivariate model, pre TAVI pulmonary artery systolic pressure was found to be an independent predictor of peri-procedural PPI [Exp(B): 0.977, 95% Confidence Interval: 0.957–0.998, B=−0.023, p=0.029]. Pre-TAVI conduction abnormalities and the degree of aortic annulus calcification, as assessed by computed-tomography, were not found to predict PPI after TAVI.
Conclusion
PPI following TAVI was not associated with survival at 27 months of follow-up, independently from the pre TAVI ejection fraction.

Abstract
Abstract
Microwave radiometry (MWR) has been applied successfully in the evaluation of carotid atherosclerosis, measuring reliably temperature heterogeneity of atherosclerotic plaques. Recent studies have shown an association between increased carotid temperature heterogeneity (ΔT) detected by MWR and cardiovascular events. Vulnerable plaques of the coronary arteries, share common characteristics such as the thin cap fibrous cap, that make the prone to rupture in the presence of stimulus such as shear stress or inflammation. Optical coherence tomography (OCT) is an imaging method, by which the fibrous cap and the presence of plaque rupture can be accurately in vivo visualized.
Purpose
To evaluate the impact of carotid temperature heterogeneity on the culprit plaque morphology on patients presenting with acute myocardial infarction.
Method
A total of 37 patients undergoing percutaneous coronary intervention (PCI) for an acute myocardial infarction who had an identifiable de novo culprit lesion in a native coronary artery, were enrolled in this study. All patients underwent PCI and Optical Coherence Study (OCT) within 12 hours since symptom onset. The OCT study was performed according to the standard techniques and acquired images were analyzed by 2 independent investigators., After the completion of the PCI all patients underwent MWR of both carotid arteries and ΔT was defined as maximal temperature detected along each carotid artery minus minimum.
Results
Thirty four patients with acute myocardial infarction 21 with STEMI (61.76%) and 13 (38.23%) with NSTEMI were included in the study. Thin cap fibroatheroma (TCFA) was present in 31 patients (91.1%), while all ruptured plaques had a TCFA compared to 11 TCFA (78.57%) observed in plaques that had no rupture (p=0.03). HsCRP was significantly increased in ruptured plaques compared to non ruptured ones (14.41±4.02 versus 9.9±2.5, p<0.005). Mean ΔT was significantly increased in ruptured plaques compared to no ruptured ones (1.01±0.31 versus 0.51±0.14°C, p<0.005), as well as in plaques with TCFA compared to those without a TCFA (0.82±0.37 versus 0.60±0.05°C, p=0.001). In the multivariate analysis DM, hsCRP, and ΔT were entered from which DM (OR 4.12; 95% CI 0.77–22.07; P=0.07) and ΔTau ((OR for 0.1°C increase 1.43; 95% CI 1.03–1.98; P=0.03) remained in the final model, with ΔT being the only variable independently associated with the presence of TCFA. Similarly regarding plaque rupture, STEMI, hsCRP, and ΔT were entered in the multivariate analysis from which hsCRP (OR 1.51; 95% CI 0.99–2.28; P=0.051) and ΔTau ((OR for 0.1°C increase 3.40; 95% CI 1.29–8.96; P=0.013) remained in the final model, with ΔT being the only variable independently associated with the presence of rupture.
Conclusions
Carotid thermal heterogeneity is associated with TCFA and plaque rupture in patients with acute myocardial infarction.

All patients underwent PCI and Optical Coherence Study (OCT) within 12 hours since symptom onset. The culprit lesion of the angiogram was clearly identified by a combination of ECG, wall motion abnormalities seen in cardiac ultrasound, and coronary angiogram. The OCT study was performed using the LightLab OCT wire, and acquired images were analyzed by 2 independent investigators using previously validated criteria for OCT plaque characterization. After the completion of the PCI all patients underwent MWR of both carotid arteries and ΔT was defined as maximal temperature detected along each carotid artery minus minimum.
Results
Thirty four patients with acute myocardial infarction 21 with STEMI (61.76%) and 13 (38.23%) with NSTEMI were included in the study. STEMI patients had more ruptured plaques compared to NSTEMI patients (71.41 versus 38.46%, p=0.053).

Conclusions
Carotid thermal heterogeneity is associated with the presence of plaque rupture in patients with acute myocardial infarction. Further studies are needed in order to assess the possible prognostic impact of carotid ΔT on such population.

Abstract
Abstract
Background
Electrocardiographic (ECG) strain has been linked to excess cardiovascular morbidity and mortality in asymptomatic patients with aortic stenosis.
Purpose
We aim to determine the differential impact of baseline ECG-strain on long-term mortality after transcatheter aortic valve implantation (TAVI).
Methods
Patients with severe and symptomatic aortic stenosis (effective orifice area [EOA]≤1cm2), who were scheduled for TAVI with a self-expanding valve between May 2015 and May 2018 were consecutively enrolled. Left ventricular strain was defined as the presence of ≥1mm convex ST-segment depression with asymmetrical T-wave inversion in leads V5 to V6 on baseline ECG. Patients were excluded, if they had bundle branch block or a permanent pacemaker at baseline. Baseline parameters were compared, and multivariate Cox proportional hazard regression models were generated to assess outcome difference. The primary clinical endpoint was cumulative mortality defined according to the criteria proposed by the Valve Academic Research Consortium-2.
Results
Of the 171 patients screened, 56 patients were excluded due to left bundle branch block or paced rhythm. In the 115 included patients (mean age: 81.4±7), 36 patients (31.3%) had strain pattern on pre-TAVI ECG. There were no differences in baseline characteristics between the two groups. During a median follow-up of 2.32 years (IQR 1.62 to 3), 11 patients (9.6%) reached the primary clinical endpoint. Patients in the strain group had higher incidence of all-cause mortality compared to patients without left ventricular strain (25% vs 2.5%, χ2=14.4, p<0.001). Kaplan-Meier survival analysis showed a significantly decreased cumulative probability of survival at 3 years in patients with LV-strain compared with patients without LV-strain (log-rank p=0.002, Figure 1). In the multivariate analysis, left ventricular strain [Exp(B): 8.952, 95% Confidence Interval (CI): 1.215–65.938, B=2.192, p=0.031] and QRS duration [Exp(B): 1.058, 95% CI: 1.022–1.095, B=0.056, p<0.001] were found to be independent predictors of all-cause mortality after TAVI.
Conclusion
Baseline ECG left ventricular strain was an independent predictor of long-term mortality post TAVI. Systematic strain measurements might aid in risk-stratifying patients scheduled for TAVI.

Abstract
PURPOSE The investigation of a semi-quantitative index in the pelvis to assess for diffuse bone marrow (BM) [18F]-FDG uptake and the investigation of PET skeletal patterns in multiple myeloma (MM) patients, in accordance with prognostic markers, clonal plasma cell (cPC) morphology, and response to therapy. METHODS We prospectively analyzed [18F]-FDG PET/CT in 90 MM patients (newly diagnosed, 60; relapsed/refractory, 30). Among other PET/CT parameters, we calculated the ratio SUVmax pelvis/liver and examined for correlations with known MM prognostic parameters, cPC morphology (good vs. low/intermediate differentiation), and response to therapy. RESULTS SUVmax pelvis/liver ratio was significantly lower for the group of good differentiation vs. intermediate/low differentiation cPCs (p < 0.001) and showed a positive correlation with BM infiltration rate, β2 microglobulin, serum ferritin, international staging system (ISS), and revised ISS; no significant correlation was found with hemoglobin. A cutoff value of 1.1 showed an excellent specificity (99%) and high sensitivity (76%) for diffuse BM involvement (AUC 0.94; p < 0.001). Mixed pattern and appendicular involvement correlated with poor prognostic features while normal pattern, found in 30% of patients, correlated with good prognostic features. Presence of ≥ 10 focal lesions negatively predicted for overall response (p < 0.05; OR 4.8). The CT component improved the diagnostic performance of PET. CONCLUSION This study showed, for the first time, that cPC morphology and markers related with MM biology, correlate with SUVmax pelvis/liver index, which could be used as a surrogate marker for BM assessment and disease prognosis; PET patterns correlate with MM prognostic features and response rates.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT-2) inhibitors are a relatively novel class of oral medications for the treatment of Type 2 DM with a generally acceptable safety profile. However, these agents have been associated with rare events of a serious and potentially life-threatening complication named euglycemic diabetic ketoacidosis (euDKA). euDKA is not identical with the typical diabetic ketoacidosis, as it often presents with serious metabolic acidosis but only mild to moderate glucose and anion gap elevation. CASE PRESENTATION We report a case of a 51-year old female with Type 2 DM treated with an SGLT-2 inhibitor, developing severe metabolic acidosis with only mild blood glucose elevation after a routine surgery. A careful evaluation of involved factors led to the diagnosis of euDKA, followed by cautious application of simple therapeutic measures that resulted in complete restoration of acidosis and glycemic control in less than 48-h. CONCLUSIONS Euglycemic ketoacidosis is a rare but rather serious complication of SGLT-2 inhibitors use, often with a multifactorial etiology. Its atypical presentation requires a high level of awareness by physicians as early recognition of this complication can quickly and safely restore acid-base balance.

Abstract
BACKGROUND Within-visit variability of repeated sequential readings of blood pressure (BP) is an important phenomenon that may affect precision of BP measurement and thus decision making concerning BP-related risk and hypertension management. However, limited data exist concerning predictive ability of within-visit BP variability for clinical outcomes. Therefore, we aimed to investigate the association between the variability of three repeated office BP measurements and the risk of all-cause mortality, independent of BP levels. METHODS Data collected through the National Health and Nutrition Examination Survey (NHANES) were analysed. NHANES is a program of studies designed to assess health and nutritional status of adults and children in the United States. A complete set of three sequential BP measurements, together with survival status, were available for 24969 individuals (age 46.8±;19.3 years, 49% males). Multivariable logistic regression models were used to determine the prognostic ability of the examined demographic, clinical, and haemodynamic indices. RESULTS Among various examined indices of variability of systolic (SBP) and diastolic (DBP) blood pressure measurements, the standard deviation of DBP (DBPSD) was the stronger independent predictor of mortality (odds ratio 1.064, 95% Confidence Interval: 1.011-1.12) after adjustment for age, sex, body mass index, smoking, SBP, heart rate, history of hypertension, diabetes mellitus, hypercholesterolaemia, and cardiovascular events. CONCLUSION Within-visit variability of three sequential office DBP readings may allow for the identification of high-risk patients better than mean SBP and DBP levels. The predictive value of within-visit BP variability and methods to improve its clinical application are worthy of further research.

Abstract
African swine fever (ASF) entered Georgia in 2007 and the EU in 2014. In the EU, the virus primarily spread in wild boar (Sus scrofa) in the period from 2014-2018. However, from the summer 2018, numerous domestic pig farms in Romania were affected by ASF. In contrast to the existing knowledge on ASF transmission routes, the understanding of risk factors and the importance of different transmission routes is still limited. In the period from May to September 2019, 655 Romanian pig farms were included in a matched case-control study investigating possible risk factors for ASF incursion in commercial and backyard pig farms. The results showed that close proximity to outbreaks in domestic farms was a risk factor in commercial as well as backyard farms. Furthermore, in backyard farms, herd size, wild boar abundance around the farm, number of domestic outbreaks within 2 km around farms, short distance to wild boar cases and visits of professionals working on farms were statistically significant risk factors. Additionally, growing crops around the farm, which could potentially attract wild boar, and feeding forage from ASF affected areas to the pigs were risk factors for ASF incursion in backyard farms.

Abstract
BACKGROUND Lymph node metastasis is a principal prognostic factor for the treatment of endometrial cancer. Added value of para-aortic lymphadenectomy to only pelvic lymphadenectomy for intermediate/high-risk endometrial cancer patients remains controversial. OBJECTIVE A systematic review and meta-analysis was performed to assess the impact of combined pelvic and para-aortic lymph node dissection (PPALND) compared to only pelvic lymph node dissection (PLND) on survival outcomes of intermediate and/or high-risk patients. STUDY DESIGN The systematic review and meta-analysis adhered to the PRISMA guidelines for meta-analyses of interventional studies. Pubmed, Scopus, EMBASE and Cochrane were searched up to April 20, 2018. Included studies were those comparing high-risk endometrial cancer patients that had performed pelvic and para-aortic lymph node dissection (PPALND) vs. only pelvic lymph node dissection (PLND) apart from standard procedure (total hysterectomy with bilateral salpingo-oophorectomy, TAHBSO). Primary outcomes of the study were overall survival and disease-free survival rates. Methodological quality of the included studies was assessed using the ROBINS-I tool. Overall quality of the evidence for the primary and secondary outcomes was evaluated as per GRADE guideline using the GRADE pro GD tool. RESULTS There were 13 studies identified with 7349 patients included. All studies were retrospective observational as no RCTs or prospective studies adhering to inclusion criteria were retrieved. Combined pelvic and para-aortic lymphadenectomy was associated with 46% decreased risk for death (HR 0.54, 95% CI 0.35-0.83, I2 = 62.1%) and 49% decreased risk for recurrence (HR 0.51, 95% CI 0.28-0.93). It was also associated with increased 5-year OS rate (RR 1.13, 95% CI 1.04-0.24, I2 = 57.3%) and increased 5-year DFS rate (RR 1.23, 95% CI 1.14-1.31, I2 = 85.5) compared with only pelvic lymphadenectomy. CONCLUSION Combined pelvic and para-aortic lymphadenectomy is associated with improved survival outcomes compared with only pelvic lymphadenectomy in women with intermediate/high-risk endometrial cancers. Further prospective studies should be performed.

Abstract
PURPOSE Our aim was to detect and evaluate potential alterations in the postoperative status of E6/E7 HPV mRNA in women treated for cervical intraepithelial lesions (CIN) and if so, to evaluate its potential use as a prognostic tool to identify patients with increased risk of treatment failure or recurrent disease. METHODS Our study retrospectively analyzed 101 women with an abnormal Pap smear, or in some cases with histological reports or molecular analysis requiring colposcopic evaluation. Thin-prep cytological samples were collected before colposcopy and histology (when necessary). After treatment, all women were scheduled for colposcopy in six months. The cytological material was analyzed with CLART-2 HPV-DNA test and HPV-PROOFER E6/E7 mRNA test. RESULTS Concerning demographics, no significant correlations were found for smoking, condom use or vaccination status. It seems that the only statistically significant correlation with actual severity came from the mRNA-test after treatment. This shows that clinical cases with more severe CIN may have higher chances of unsuccessful treatment. At the first post-op visit, 83.5% of HPV mRNA-positive women had a negative HPV mRNA-test while only 60.4% of HPV DNA-positive women became negative. There were 12 HPV-mRNA positive patients both before and after treatment, 3 of whom had a negative HPV DNA test, meaning that, if based only on HPV-DNA results, they would have been managed wrongly as successfully treated patients. Our study shows that E6/E7 mRNA detection has particularly high specificity and positive likelihood ratio for the prediction of treatment failure in comparison with HPV DNA-testing. CONCLUSIONS E6/E7 mRNA overexpression seems to be a promising candidate as an indicator-biomarker to determine the success of treatment.

Abstract
Abstract
Background
Central hemodynamics and especially wave reflection amplification exhibit a vital parameter of chronic heart failure (CHF) physiology. Erectile dysfunction (ED) displays a poor peripheral vessel rheology and serum prolactin role is still debated in CHF mechanisms. The Mediterranean diet (Med-diet) is famous for its vasoprotective and wellbeing properties.
Purpose
To investigate the effect of the Med-diet in central hemodynamics, erectile status, atheroma formation and serum prolactin levels in male patients with chronic heart failure.
Methods
123 CHF male patients under optimal medical therapy enrolled the study (mean age: 65±8 yo, NYHA class II, ejection fraction <40%). All underwent evaluation of the carotid – femoral pulse wave velocity (PWV), estimation of central pressures and augmentation index (AIx) as parameter of wave reflection amplification (sphygmocor device). Ejection fraction (EF) of the left ventricle was estimated by using 2D echocardiography (Simpson method). ED severity and adherence to the Med-diet were assessed by the SHIM-5 (range: 0–25) and the Med-diet (range: 0–55) scores. Higher values point to better erectile function and a great Med-diet compliance respectively. Detection of atheroma was based on the intima- media thickness (IMT) of the common carotid artery. Prolactin levels were assessed in morning blood samples taken before 09:00 am.
Results
The SHIM −5 score (mean: 12±4) was associated to the AIx (p=0,03, r=0,75) and both positively and strongly related to the Med-diet score (p=0,01, r=0,8 and p=0,01, r=0,75 respectively). Med-diet compliance was negatively associated to IMT (p=0,02, r=−0,8) and serum prolactin levels (p=0,03, r=−0,6).Moreover, we notice a positive association between prolactin and the IMT (p=0,04, r=0,7). By multiple linear regression analysis the relation of SHIM-5 and Med-diet score remained significant (p=0,04) after adjustment for BMI, central pulse and mean arterial pressures. We further subdivide our population according to the mean Med-diet value (28) into high and low Med-diet adherence groups. Only in the group with the greater Med-diet adherence (n=73, 60%) AIx was strongly associated to the SHIM-5 score (p=0,02) even after adjustment for PWV, age and BMI. Prolactin levels there were still related to IMT (p=0,04) after adjustment for PWV, AIx, BMI and central pulse pressure. All statistics remained significant when adjusting for ejection fraction of the left ventricle.
Conclusion
High adherence to the Med-diet benefits CHF hemodynamics by enforcing wave reflection amplification, thus generating a stronger pulse signal to peripheral vasculature. Moreover suppresses serum prolactin levels that relates to atheroma formation. Both actions enhance erectile performance independently of the EF of the left ventricle. It is important to advise CHF patients to adopt this dietary pattern in order to improve hemodynamic status and the sense of wellbeing.

Abstract
Objective: Human papilloma virus (HPV) vaccination may result in misconceptions that encourage young women to adopt risky contraceptive practices. The purpose of this article was to investigate whether HPV vaccination status was associated with choice of contraceptive method and adoption of risky sexual behaviour. Methods: Vaccinated and non-vaccinated visitors to a university department paediatric and adolescent gynaecology clinic were asked to anonymously fill in a survey comprising questions on sociodemographic characteristics, sexual history, opinions on contraception and attitudes towards contraception. Results: A total of 191 women were studied, 75 (39.3%) of whom had received the HPV vaccination and 116 (60.7%) of whom had not. The main contraceptive methods used in both groups were male condom (46%), emergency contraception (14%) and coitus interruptus (12%). The vaccinated group was less religious and had better educated mothers compared with the non-vaccinated group (relative risk [RR] 0.64; 95% confidence interval [CI] 0.45, 0.93; p = .016 vs RR 1.91; 95% CI 1.01, 3.63; p = .027, respectively). They also had an earlier sexual debut (RR 1.94; 95% CI 1.06, 3.55; p = .015), agreed that vaccination increased the safety of sex (RR 1.45; 95% CI 1.02, 2.05; p = .039) and considered the HPV vaccine a prerequisite to initiation of a sexual relationship (RR 1.87; 95% CI 1.34, 2.63; p < .001). Conclusion: HPV vaccination did not affect sexual behaviour, attitudes to condom use or choice of contraceptive method.

Abstract
The aim of this study was to investigate the prognostic value of the Hedgehog (Gli, Patched-1, Shh, Smo) and Notch (Jag1, Notch2, Notch3) pathway members, in comparison to a panel of proteins (ER, PgR, HER2/neu, Ki67, p53, p16, PTEN and MMR) previously suggested to be involved in the pathogenesis of endometrial cancer, in association with clinical outcome and standard clinicopathological characteristics. A total of 204 patients with histological diagnosis of endometrial cancer treated from 2004 to 2013 were included. The evaluation of protein expression was assessed by immunohistochemistry. Univariate analysis showed that higher Ki67 labeling, expression of PTEN, p16, Notch2 and Notch3 proteins, as well as MMR proficiency were associated with increased relapse and mortality rate. Additionally, Patched-1 protein expression was associated with worse DFS, while p53 overexpression was associated with worse OS. In multivariate analyses, patients with MMR proficient tumors had more than double risk for death than patients with MMR deficient (MMRd) tumors (adjusted HR = 2.19, 95% CI 1.05–4.58, p = 0.036). Jag1 positivity conferred reduced mortality risk (HR = 0.48, 95% CI 0.23–0.97, p = 0.042). However, as shown by hierarchical clustering, patients fared better when their tumors expressed high Jag1 protein in the absence of Notch2 and Notch3, while they fared worse when all three proteins were highly expressed. Patched-1 positivity conferred higher risk for relapse (HR = 2.04, 95% CI 1.05–3.96, p = 0.036). Aberrant expression of key components of the Notch and Hedgehog signaling pathways, as well as MMRd may serve as independent prognostic factors for recurrence and survival in patients with endometrial cancer.

Abstract
BACKGROUND Tissue genomic heterogeneity (t-HET) in patients with epithelial ovarian cancer (OVCA) is related to tissue plasticity, i.e., flexibility to adapt to adverse molecular environments. Here, we interrogated the presence and clinical relevance of OVCA t-HET. METHODS We applied high-depth (>2000×) sequencing on 297 paraffin tissue samples (fallopian tubes, ovaries, intra-abdominal metastases) from 71 treatment-naïve patients who subsequently received first-line platinum-based chemotherapy. Based on tissue mutation patterns, we distinguished tissue genotypes into: no mutation (33/297 samples; 11.1%), stable (173; 58.2%) and unstable (91; 30.7%). We profiled genotypes per patient and assessed t-HET in 69 patients. Predicted pathogenic mutations refer to germline and/or tissues. RESULTS Among all 71 patients, 46 (64.8%) had pathogenic BRCA1 mutations and 15 (21.7%) had BRCA1/2 disruption (i.e., pathogenic mutations with position-LOH). We classified 29 patients with t-HET (42%), all with pathogenic BRCA1; t-HET was observed in 64% with such mutations (p < 0.001). As opposed to non-t-HET, matched tissues in t-HET shared pathogenic BRCA1 (p < 0.001) but not BRCA2 and TP53. Germline BRCA1 mutations in tissues exhibited position-LOH; heterozygous status; or, partial loss of the inherited allele accompanied by additional clonal mutations. Patients with t-HET had worse outcome (log-rank p = 0.048 [progression-free]; p = 0.037 [overall survival]), including 12/15 patients with disrupted BRCA1/2 and 3 BRCA1 carriers with partial germline loss in tissues. CONCLUSIONS Pathogenic BRCA1 mutations appear necessary but may not be sufficient for the establishment of t-HET. t-HET may be associated with worse outcome, including in patients with disrupted BRCA1/2, which is usually considered as a favourable marker. OVCA t-HET may need to be addressed for treatment decisions.

Abstract
The aim of these case reports is to present the feasibility of isthmo-neovagina anastomosis after Davydov's colpopoiesis in patients with Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) with a rudimentary uterine horn. Ten MRKH patients were treated surgically with laparoscopic Davydov's vaginoplasty between 2006 and 2012. Two of these patients were found to have a functional rudimentary uterine horn. These patients underwent a 2-step surgical intervention: (1) Davydov's colpopoiesis with a combined laparoscopic and perineal approach and (2) isthmo-neovagina anastomosis with laparotomy in the 2 cases with a uterine horn in a second surgical step 4 and 6 months after the initial procedure, respectively. The main outcome measures were the perioperative and postoperative details, the vaginal length during follow-up, the postoperative initiation of intercourse, and the postoperative menstrual function. Isthmo-neovagina anastomosis was uneventful, and there were no early postoperative complications. The mean hospitalization duration was 9.5 days. Anastomosis was successful in both patients. The mean follow-up was 42 months, and the mean vaginal length was measured 9.5 cm; both patients reported normal intercourse and normal menstrual function. Anatomic restoration of the genital tract in these patients appears to have been successful and led to functional menstruation and restitution of the patients' sex life.

Abstract
Abstract
Cyclin D1 is an important molecular driver of human breast cancer but better understanding of its oncogenic mechanisms is needed, especially to enhance efforts in targeted therapeutics. Activation of the cyclin D1 oncogene, often by amplification or rearrangement, is a major driver of multiple types of human tumors including breast and squamous cell cancers, B-cell lymphoma, myeloma, and parathyroid adenoma. The cyclin D1 gene is amplified or overexpressed in up to half of human breast cancers and its mammary-targeted overexpression induces mammary tumorigenesis in mice. Cyclin D1 encodes the regulatory subunit of the cyclin-dependent kinase (CDK) holoenzyme that phosphorylates several substrates including the retinoblastoma protein (pRb) to advance the G1S cell cycle checkpoint, promote DNA synthesis and regulate NRF-1 to inhibit mitochondrial biogenesis thereby coordinating nuclear and mitochondrial functions.
In addition to cyclin D1's function as a regulatory subunit of a CDK holoenzyme, several CDK-independent functions have been identified. Tumors overexpressing cyclin D1 tend to display normal levels of proliferation and expression of E2F target genes, which contrasts with tumors overexpressing cyclin E or an activator for pRb. Breast cancers overexpressing cyclin D1 that are wild type for pRb have relatively normal proliferation rates, in contrast to those caused by genetic inactivation of pRb, which show significantly increased proliferation rates. Furthermore, the alternate splice form of cyclin D1, (cyclin D1b), has potent transforming ability, which does not correlate with the ability to phosphorylate the pRb protein. Several other properties of cyclin D1 have been identified including the induction of cellular migration and enhanced angiogenesis, inhibition of mitochondrial biogenesis, and mediating DNA-damage repair signaling. Cyclin D1 binding proteins participating in these putatively CDK-independent functions include PACSIN2, NRF1, and p27KIP1; binding to p27KIP1 and PACSIN2 contribute to the pro-migratory function of cyclin D1.
Currently, pharmaceutical initiatives to inhibit cyclin D1 are focused on the catalytic component since the transforming capacity is thought to reside in the cyclin D1/CDK activity. We initiated the following study to directly test the oncogenic potential of catalytically inactive cyclin D1 in an in vivo mouse model that is relevant to breast cancer. Herein, transduction of cyclin D1-/- mouse embryonic fibroblasts (MEFs) with the kinase dead KE mutant of cyclin D1 led to aneuploidy, abnormalities in mitotic spindle formation, autosome amplification, and chromosomal instability (CIN) by gene expression profiling. Acute transgenic expression of either cyclin D1WT or cyclin D1KE in the mammary gland was sufficient to induce the CIN signature within 7 days. Sustained expression of cyclin D1KE induced mammary adenocarcinoma with similar kinetics to that of the wild-type cyclin D1. ChIP-Seq studies demonstrated recruitment of cyclin D1WT and cyclin D1KE to the genes governing CIN. We conclude that the CDK-activating function of cyclin D1 is not necessary to induce either chromosomal instability or mammary tumorigenesis.

Abstract
BACKGROUND Primary malignant vascular tumors of bone are very rare accounting for less than 1% of primary bone malignancies. They are characterized by unknown etiology, variable biologic behavior and histological appearance. Angiosarcoma is an aggressive malignant vascular tumor derived from mesenchymal cells with endothelial differentiation. CASE REPORT We present a rare case of angiosarcoma of bone in a 47-year-old male operated for a lumbar disk herniation. During his transportation from the operation theater, a pathological intertrochanteric fracture of the right hip occured. The magnetic resonance imaging (MRI) revealed a bone lytic lesion located into the great trochanter of the right femur. Open surgical biopsy of the lesion was performed and the histological examination showed primary angiosarcoma of bone. The treatment included radiotherapy (300 cGy per fraction in 13 days) followed by excision of the proximal femur and custom made total hip arthroplasty. The diagnosis was confirmed on the surgical specimen.
