Sentinel lymph node biopsy for breast cancer during pregnancy: A comprehensive update.

BACKGROUND: Pregnant patients diagnosed with breast cancer (PrBC) may receive substantially different treatments compared to general population, considering that certain treatment options cannot be applied during pregnancy due to their potential harmful effects to the foetus. Regarding the use of sentinel lymph node biopsy (SLNB) in pregnant patients, potential concerns include foetal harm from radiation exposure, possible teratogenic effects of blue dyes and maternal anaphylaxis to isosulfan. OBJECTIVE: The main objective of the present systematic review is to summarize and present current knowledge and up-to-date evidence about the safety and efficacy of SLNB in PABC. METHODS: MEDLINE, Google Scholar and UpToDate databases were searched up to 22 January 2023. Articles studying the safety and effectiveness of SLNB in patients for PrBC were eligible for inclusion in the present review. RESULTS: In total, 63 articles that met the inclusion criteria were included in this study. Forty-seven articles were strongly in favour of performing SLNB in PABC, 4 articles were partially in favour, 10 articles were strongly against and 2 articles were partially against performing SLNB in PABC. Sub-categorization based on type of study showed that the majority of studies in favour were of higher level of evidence than those against. Furthermore, there were overall 12 studies reporting on outcomes. There were overall 382 women with PrBC that underwent SLNB. Full data were reported for 237 cases. Overall live birth rate was 95.8%, while overall neonatal complication rate was 3.4%. No case of maternal side effects or anaphylactic reaction, maternal death, stillbirth and neonatal death was reported (0%). CONCLUSIONS: Sentinel lymph node biopsy seems to be safe and effective technique for breast cancer during pregnancy.

Diagnostic comparison of electrical impedance spectroscopy with colposcopy and HPV mRNA-testing in the prediction of CIN2+ women in Greece.

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.

Contraceptive methods in adolescence: a narrative review of guidelines.

PURPOSE: Adolescent pregnancy, while recently in decline, remains a matter in need of addressing. Education and counselling are deemed crucial and this review aims at comparing published contraceptive guidelines, thus resolving any surrounding misconceptions. MATERIALS AND METHODS: Recently published contraception guidelines regarding adolescent pregnancy were retrieved. In particular, guidelines and recommendations from ACOG, RCOG, SOCG, AAP, CPS, NICE, CDC, and WHO were compared and reviewed based on each guideline's method of reporting. RESULTS: Three categories of contraceptive methods are available for adolescents and recommendations on their initiation should be made based on their efficacy, according to all guidelines. Therefore, long acting reversible contraceptives (LARCs) should be highly recommended as the most effective method (typical use failure rate: 0.05%), followed by short-acting hormonal contraceptives (typical use failure rate: 3-9%). The third contraceptive option includes contraceptives used in the moment of intercourse and displays the lowest effectiveness (typical use failure rate: 12-25%), mostly due to its dependence on personal consistency, however offers protection against STI transmission. CONCLUSION: Adolescents should be encouraged to initiate contraception, with LARCs being the primary choice followed by short-acting hormonal contraception. However, regardless of the chosen effective contraceptive method, the use of condom is necessary for STI prevention.

Adolescent pregnancy, while recently in decline, remains a matter in need of addressing. The use of contraceptive methods such as LARCs and short-acting hormonal contraceptives should be encouraged and suggested based on effectiveness with the addition of condom for STI prevention.

Epithelial Ovarian Cancer: A Five Year Review.

Ovarian cancer is a malignant disease that affects thousands of patients every year. Currently, we use surgical techniques for early-stage cancer and chemotherapy treatment combinations for advanced stage cancer. Several novel therapies are currently being investigated, with gene therapy and stem cell therapy being the corner stone of this investigation. We conducted a thorough search on PubMed and gathered up-to-date information regarding epithelial ovarian cancer therapies. We present, in the current review, all novel treatments that were investigated in this field over the past five years, with a particular focus on local treatment.

The expression and possible role of corticotropin-releasing hormone family peptides and their corresponding receptors in gynaecological malignancies and premalignant conditions: a systematic review.

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.

The role of endoglin and its soluble form in pathogenesis of preeclampsia.

Preeclampsia remains till today a leading cause of maternal and fetal morbidity and mortality. Pathophysiology of the disease is not yet fully elucidated, though it is evident that it revolves around placenta. Cellular ischemia in the preeclamptic placenta creates an imbalance between angiogenic and anti-angiogenic factors in maternal circulation. Endoglin, a transmembrane co-receptor of transforming growth factor ß (TGF-ß) demonstrating angiogenic effects, is involved in a variety of angiogenesis-dependent diseases with endothelial dysfunction, including preeclampsia. Endoglin expression is up-regulated in preeclamptic placentas, through mechanisms mainly induced by hypoxia, oxidative stress and oxysterol-mediated activation of liver X receptors. Overexpression of endoglin results in an increase of its soluble form in maternal circulation. Soluble endoglin represents the extracellular domain of membrane endoglin, cleaved by the action of metalloproteinases, predominantly matrix metalloproteinase-14. Released in circulation, soluble endoglin interferes in TGF-ß1 and activin receptor-like kinase 1 signaling pathways and inhibits endothelial nitric oxide synthase activation, consequently deranging angiogenesis and promoting vasoconstriction. Due to these properties, soluble endoglin actively contributes to the impaired placentation observed in preeclampsia, as well as to the pathogenesis and manifestation of its clinical signs and symptoms, especially hypertension and proteinuria. The significant role of endoglin and soluble endoglin in pathophysiology of preeclampsia could have prognostic, diagnostic and therapeutic perspectives. Further research is essential to extensively explore the potential use of these molecules in the management of preeclampsia in clinical settings.

Axillary lymph node dissection vs. sentinel node biopsy for early-stage clinically node-negative breast cancer: a systematic review and meta-analysis.

ΟBJECTIVE: This study aimed at comparing survival outcomes between systematic axillary lymph node dissection (ALND) vs sentinel lymph node and axillary lymph node dissection only if sentinel positive (SLN ± ALND) in early-stage, clinically node-negative breast cancer patients. ΜETHODS: A systematic review and meta-analysis adhered to PRISMA guidelines was performed. Included studies were prospective randomized controlled trials (RCTs) comparing survival outcomes of ALND vs. SLN ± ALND in early-stage, node-negative breast cancer patients. Patients enrolled were only those with tumor size lower than 4 cm, clinically negative nodes and treated with breast-conservative surgery. Primary endpoints were locoregional recurrence, overall death and cancer-related death. RESULTS: There were four studies included in the analysis, enrolling overall 2982 patients, of which 1494 in ALND arm and 1488 in the SLN ± ALND arm. No statistically significant difference was observed in locoregional recurrence, breast cancer-related death and overall death. Locoregional recurrence was observed in 2.8% (ALND) vs. 4.1% (SLND ± ALND), (RR 0.69, 95% CI 0.20-2.30). Overall death rate was 7.0% vs. 6.8% respectively, (RR 1.00, 95% CI 0.73-1.39, I2 = 28.7%). Breast cancer-related death was 3.6% vs. 3.5%, respectively (SLN ± ALND), (RR 1.11, 95% CI 0.70-1.78, I2 = 0%). No statistically significant difference was observed in any of secondary study outcomes. CONCLUSIONS: Systematic axillary axillary lymph node dissection provides no survival benefit compared with sentinel lymph node dissection for early-stage clinically node-negative breast cancer patients.

Outcomes of robotic and laparoscopic surgery for benign gynaecological disease: a systematic review.

Benign gynaecological diseases are usually treated with minimally invasive approaches. Robotic surgery seems an alternative to laparoscopic surgery. No definitive conclusions have yet been made regarding comparison of robotic versus laparoscopic surgery for benign diseases. In this scenario, we performed a systematic review in order to assess the advantages and disadvantages of laparoscopy versus robotic surgery and conclude whether laparoscopy should be replaced by robotic surgery for the treatment of benign gynaecological conditions, following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Statement. We included 64 studies: no significant difference was observed regarding overall complication rate; no significant benefit of robotic approach was demonstrated regarding length of hospital stay and conversion to laparotomy; furthermore, robotic surgery is more easily used by non-experienced surgeons, while it is more expensive and characterised by longer operative time. In conclusion, current evidence indicates neither statistically significant nor clinically meaningful differences in surgical outcomes between robotic and laparoscopic surgeries for benign gynaecological diseases. Impact statementWhat is already known on this subject? Benign gynaecological diseases are usually treated with minimally invasive approaches. Nevertheless, no definitive conclusions have yet been made regarding comparison of robotic versus laparoscopic surgery for benign diseases.What do the results of this study add? No significant difference was observed regarding overall complication rate; no significant benefit of robotic approach was demonstrated regarding length of hospital stay and conversion to laparotomy; furthermore, robotic surgery is more easily used by non-experienced surgeon, while it is more expensive and characterised by longer operative time.What are the implications of these findings for clinical practice and/or further research? Robotic surgery should not replace laparoscopy for the treatment of benign gynaecological conditions; in addition, gynaecologic surgeon should offer robotic surgery for benign diseases only after a proper counselling and a balanced decision-making process involving the patient.

COVID-19 transmission in surgical smoke during laparoscopy and open surgery: a systematic review.

AIM: To evaluate the risk of SARS-CoV-2 transmission in surgical smoke and aerosols during laparoscopy and open surgery. MATERIAL AND METHODS: A systematic review (PROSPERO ID: CRD42021268366) was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were selected based on the title and abstract as well as the type of publication. Primary objectives of the study were to assess potential risk of contamination as well as comparing laparoscopic and open procedures in terms of danger of SARS-COV-2 transmission. RESULTS: Fifty-three articles were identified and included in the review. No case of SARS-CoV-2 transmission to operating room personnel during open or minimally invasive surgery was identified at the time the review was conducted. Furthermore, no significant difference was observed between smoke and aerosols generated from open surgery and those generated from minimally invasive surgery. CONCLUSION: COVID-19 transmission in surgical smoke and aerosols has yet to be observed. However, given the potential risk of viral transmission, caution should be exercised when performing surgery to ensure the safety of the operating room personnel. When clinically indicated and when protective measures can be implemented, minimally invasive surgery should be performed instead of open surgery to ensure optimal patient outcomes.

Endobag use in laparoscopic gynecological surgeries: a systematic review.

PURPOSE: The purpose of this systematic review was to assess the characteristics of endobags present in the market, the weight of specimen removed, complications of the operations and time required for in-bag morcellation in women undergoing laparoscopic gynecologic surgeries. MATERIAL AND METHODS: We performed a systematic review, including prospective and retrospective studies, with or without randomized allocation of the patients, using endobags in laparoscopic gynecologic surgeries. We extracted data about study design, type and price of bag used, type of surgical procedure, specimen weight, mean time for morcellation and for total surgical procedure, complications. RESULTS: We included 11 studies, including a total of 1160 patients, in which the investigators used MorSafe, Endocatch II autosuture, More-Cell-Safe, Endocatch, EcoSac and LapBag. A wide range of specimens were morcellated with the largest successfully morcellated specimen weighing 2314 gr. Only half of the studies comparing uncontained and contained morcellation found a significant increase of total operative time. Finally, the number of complications was not increased when endobag was used. CONCLUSION: According to our systematic review, in-bag (contained) morcellation can be considered as a safe and unexpensive option, associated with a very low number of complications, even with large specimens.

Sentinel lymph node mapping in endometrial cancer to reduce surgical morbidity: always, sometimes, or never.

Introduction: Surgical staging of nodal status is of utmost significance to determine the stage of endometrial cancer and construct a targeted treatment plan. Systematic lymphadenectomy has for years been the procedure of choice for staging purposes, enabling thorough assessment of lymph nodes. Nevertheless, it is associated with increased morbidity and severe postoperative complications. In an attempt to avoid the disadvantages of lymphadenectomy, the use of sentinel lymph node (SLN) biopsy has been examined as an alternative staging procedure.The purpose of the present review is to summarize and provide up-to-date evidence about the role of SLN biopsy in the staging and management of endometrial cancer cases in the terms of optimal technique, efficacy, safety, and postoperative morbidity, as an alternative approach to regional lymphadenectomy. Material and methods: A thorough literature search was conducted in MEDLINE and SCOPUS to identify recent primary research and previous review articles that explore the use of SLN mapping as a staging procedure in patients with endometrial cancer. Results: There is increasing evidence that SLN mapping is efficient in identifying metastatic nodal disease without compromising oncological safety, achieving comparable or even superior detection rates to those of lymphadenectomy, when optimal technique and careful intraoperative nodal assessment are applied. Conclusions: Sentinel lymph node mapping can safely replace lymphadenectomy as an acceptable alternative staging method for endometrial cancer; however, future research might further strengthen this suggestion by resolving potential areas of doubt and debate, especially for high-risk endometrial cancer cases.

Neoadjuvant chemotherapy in advanced-stage ovarian cancer - state of the art.

Ovarian cancer represents the fifth cause of cancer death among women, carrying one of the worst prognoses among gynaecological malignancies. The need to achieve no residual disease after surgery in order to optimize prognosis of advanced-stage ovarian cancer introduced the idea of neoadjuvant chemotherapy. The present review aims to summarize current state-of-the-art evidence regarding the efficacy and safety of neoadjuvant chemotherapy as well as novel insights regarding the usage of modern therapeutic regimens in the context of neoadjuvant chemotherapy. The last decade has been characterized by the breakthrough scientific evidence that neoadjuvant chemotherapy followed by interval debulking surgery for advanced-stage ovarian cancer may be comparable to primary debulking surgery. Neoadjuvant chemotherapy followed by interval debulking surgery is an acceptable - if not preferable - therapeutic approach in advanced-staged ovarian cancer patients because it is associated with higher optimal debulking surgery, fewer complications, and non-inferior survival outcomes. The addition of bevacizumab to chemotherapy contributes significantly to survival outcomes without causing side effects that outbalance the benefits. Patients with recurrent high-grade serous ovarian cancer and a germline or breast cancer mutation should be offered maintenance olaparib after a response to platinum-based chemotherapy. Finally, the role of hyperthermic intraperitoneal chemotherapy in the context of neoadjuvant chemotherapy remains unjustified.

Circulating serum and plasma levels of micro-RNA in type-1 diabetes in children and adolescents: A systematic review and meta-analysis.

BACKGROUND: Type 1 diabetes mellitus (T1DM) is a complex metabolic disorder characterized by hyperglycaemia, with constantly increasing incidence in paediatric population. The discovery of new molecules, such as microRNAs, and their possible interactions with T1DM create novel aspects in the diagnosis of the disease. METHODS: This systematic review and meta-analysis adhered to PRISMA guidelines. MEDLINE, SCOPUS, Cochrane CENTRAL and Clinicaltrials.gov. were searched up to 20 April 2020. Inclusion criteria for individual studies were quantification of microRNAs in serum/plasma samples and study groups consisting of children and adolescents with T1DM and healthy controls. Primary outcome of the study was the qualitative expression of microRNAs between the two groups. Statistical analysis was performed with Comprehensive Meta-Analysis Software v3.0. Methodological quality of included studies was assessed using Newcastle-Ottawa scale. RESULTS: A total of 484 studies were retrieved from the initial search of the databases. These were subsequently limited to seven included studies. Seven microRNAs demonstrated contrasting expression between the two groups, with two of them showing significant overexpression in T1DM group (miR-181:95% CI: 0.429 to 1.341 P < .001, miR-210:95% CI: 0.381 to 0.852, P < .001) and one micro-RNA being significantly overexpressed in control group (miR-375:95% CI: 0.293 to 1.459, P = .003). CONCLUSION: A total of three micro-RNA molecules appeared to have a significantly different expression in T1DM patients, serving as a possible diagnostic panel of biomarkers. These findings may contribute as reference for future research to further support the use of microRNAs as a novel diagnostic tool in T1DM.

BIOPSAR study: ultrasound-guided pre-operative biopsy to assess histology of sarcoma-suspicious uterine tumors: a new study protocol.

BACKGROUND: The pre-operative differential diagnosis between a uterine leiomyoma and a sarcoma can be a challenge. Available diagnostic tools have difficulty distinguishing between the two pathologies. PRIMARY OBJECTIVE: Τo evaluate the possibility of a pre-operative pathological diagnosis of atypical uterine muscle tumors by vaginal ultrasound-guided biopsy (VUGB). STUDY HYPOTHESIS: Diagnostic performance of ultrasound-guided biopsy will be capable of differentiating a leiomyoma from a sarcoma with a sensitivity of >90%. TRIAL DESIGN: A prospective multi-center interventional study will be performed at 10 tertiary French centers. Vaginal ultrasound Doppler examination and pelvic magnetic resonance imaging will be performed before surgery. VUGB will then be performed by a specialist radiologist. The biopsy will be obtained by performing transvaginal ultrasound under local anesthesia with lidocaine using a 16G needle. At least 4-5 specimens will be obtained in order to provide a histopathological diagnosis. All patients included in the study will be operated by laparotomy. All patients included in the study will be followed up for the subsequent 3 years according to their pathological results. MAJOR INCLUSION/EXCLUSION CRITERIA: All patients >35 years old diagnosed with a suspicious uterine tumor will be included. PRIMARY ENDPOINT: Sensitivity of VUGB on pathological diagnosis. SAMPLE SIZE: Considering a sensitivity of 90% (H0) as acceptable and a sensitivity of 95% (H1) as excellent, a sample size of 250 evaluable patients will be necessary to achieve 80% statistical power with a 5% type 1 statistical error. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Accrual will be completed in December 2024 with results presented in December 2029. TRIAL REGISTRATION: Institutional Review Board (Ethic Committee of Paris Ile de France 6) no 2018-A02343-52.

Diagnostic performance of HPV E6/E7 mRNA testing towards HPV-DNA testing and p16/Ki67 immunostaining as a biomarker of high-risk HPV recurrence in Greek women surgically treated for their cervical lesions.

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.

Closed vs. Open Oocyte Vitrification Methods Are Equally Effective for Blastocyst Embryo Transfers: Prospective Study from a Sibling Oocyte Donation Program.

PURPOSE: To assess whether open and closed vitrification protocols are equally effective for sibling-oocyte cycles when performing blastocyst embryo transfers. MATERIALS AND METHODS: A prospective study was set up comparing the open and the closed vitrification techniques in oocyte recipients sharing sibling oocytes between 2014 and 2016. Sibling oocytes were randomly and equally assigned into the closed group (oocytes vitrified in a closed system) or the open group (oocytes vitrified in an open system). Intracytoplasmic sperm injection was performed on all cases. Embryo transfers were performed on day 5. Power analysis calculation showed that 94 cycles would be needed for each group in the study in order to achieve statistical significance at a 5% level with power 80%. RESULTS: The final number of donors included was 95. A total of 190 recipients matched with their donors were included in the study. There was no difference in the mean number of oocytes vitrified with the closed or the open system (8.26 ± 2.54 vs. 8.31 ± 2.57). No significant difference was observed between the 2 groups regarding survival rate, fertilization rate, cleavage rate, top-quality embryos on day 3, blastocyst rate, and top-quality blastocyst rate. Moreover, no statistically significant difference in the b-human chorionic gonadotropin-positive rate, clinical pregnancy rate per cycle, implantation rate, ongoing pregnancy rate, and live birth rate between closed and open groups. CONCLUSION: Οpen and closed vitrification protocols are equally effective for sibling-oocyte cycles.

Combined pelvic and para-aortic is superior to only pelvic lymphadenectomy in intermediate and high-risk endometrial cancer: a systematic review and meta-analysis.

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.

The impact of sperm DNA fragmentation on ICSI outcome in cases of donated oocytes.

PURPOSE: The aim of this study is to evaluate the sperm DNA fragmentation index (DFI) in oocyte donation cycles and correlate it with the sperm parameters, the male characteristics, the embryo quality and the outcome of intracytoplasmic sperm injection (ICSI). METHODS: A total of 150 couples participating in an oocyte donation program were included in the study. Sperm samples were assessed by conventional sperm analysis. DFI was evaluated using the Halosperm kit, a sperm chromatin dispersion test (SCD). RESULTS: The relations between DNA damage and epidemiological male factors (age, height, weight), standard semen parameters (concentration, total and forward motility, and morphology), and embryological and clinical parameters (fertilization rate, total blastocyst number, number of good quality blastocyst, clinical pregnancy) were analyzed. DFI was positively correlated with advanced male age (r = 0.23, p < 0.05) and negatively correlated with total sperm and forward motility (r = - 0.29, r = - 0.27, respectively; p < 0.05). DFI was not significantly correlated with pregnancy outcome in oocyte donation cycles (r = - 0.05, p > 0.05). When good quality blastocysts were chosen, a trend toward the development of good quality embryos was detected in the presence of a low DFI (r = - 0.20, p = 0.08). CONCLUSIONS: DFI does not significantly affect the outcome of ICSI in oocyte donation cycles. Even in cases of advanced paternal age that a high DFI resulted sperm DNA fragmentation seems not to adversely affect the final outcome.

Implementation of Fetal Cardiac Guidelines for the Routine Second-Trimester Heart Examination: A Feasibility Study.

PURPOSE: This study aimed to explore the feasibility of implementation of the ISUOG 2013 guidelines on routine second-trimester examination of the fetal heart. MATERIALS AND METHODS: This was a prospective study in 357 women with singleton pregnancy undergoing their routine second-trimester scan. The fetal heart was examined using B-mode in different planes according to the guidelines. Potential maternal and fetal factors that can affect the rates of diagnostic-quality imaging for each of the recommended views were tested, using regression analysis. The intra- and interobserver agreement was analyzed in stored video loops. RESULTS: Most cardiac structures could be successfully examined with rates at or close to 100 %. Structures with a successful examination rate of ≤ 85 % included the ventricular wall fine details (55.2 %), tricuspid valve insertion (82.6 %), aortic root with clear walls (77.9 %), pulmonary artery walls (65.8 %) and clear view of the great artery walls (66.7 %). Common factors affecting the likelihood of successful examination of these structures included maternal BMI, skin-to-crux distance and the orientation of the cardiac axis. A post-hoc analysis indicated that a lack of pre-defined criteria for diagnostic quality was a constant reason for the interobserver variation. CONCLUSION: Most of the cardiac views can be consistently and reliably obtained, with maternal habitus being the primary factor limiting the quality of visualization. As offline interpretation may be subjective, using pre-defined quality criteria for the assessment of the images might improve interrater agreement.

Prevalence of smoking during pregnancy and associated risk factors: a cross-sectional study in Northern Greece.

Background: Many pregnant women smoke despite the extensive data available on the detrimental perinatal outcomes. The aim of this study was to estimate the prevalence of smoking during pregnancy and to identify the factors associated with smoking among pregnant women in Northern Greece. Methods: A sample of pregnant women (mean gestational age: 12.6 weeks) participated in a cross-sectional study assessing the prevalence of smoking. Univariate and multivariate logistic regression analyses were used to examine the factors associated with their smoking behavior. Results: A total of 3688 pregnant women (mean age: 31.1 ± 5.0 years) completed the survey. On the basis of their answers, 36.1% (n = 1330) were smokers before pregnancy and 13.2% (n = 487) were still smoking at the end of the first trimester. Eight hundred and forty-three women (63.4%) gave up smoking, apparently motivated by their pregnancy. A multivariate analysis showed an independent positive association of nulliparity, Greek ethnicity, age >35 years and a BMI > 30 with smoking before pregnancy. Smoking during pregnancy was more common among naturally conceived pregnancies and women with a BMI > 30.Cessation rates were lower for naturally conceived pregnancies, immigrants and multiparous women. Conclusion: About one third of women who smoked before pregnancy continued to smoke during pregnancy. Naturally conceiving, multiparous and immigrant women are less likely to quit smoking when pregnant. Tailored smoking cessation interventions should target women early in their pregnancy.
