Comparison end-to-end anastomosis with ostomy after secondary surgical cytoreduction for recurrent high-grade serous ovarian cancer: observational single-center study.

We conducted an observational single-center cohort study on patients with recurrent high-grade serous ovarian carcinoma that underwent secondary surgical cytoreduction with extent of partial ileectomy and/or colectomy, followed by adjuvant chemotherapy (Paclitaxel-Carboplatin). All patients performed previously primary debulking surgery without residual disease, followed by three cycles of adjuvant chemotherapy. The aim of this study was to compare survival in patients with ostomy or end-to-end anastomosis that underwent secondary cytoreduction. Furthermore, we investigated the morbidity, the rate, timing and complications of the ostomy or end-to-end anastomosis after secondary cyto-reduction.

The short form endometriosis health profile questionnaire (EHP-5): psychometric validity assessment of a Croatian version.

PURPOSE: To translate, adapt and validate the Endometriosis Health Profile-5 (EHP-5) in Croatian population. METHODS: This validation study is a part of a prospective, observational study (EHP-5 CRO) with aim of implementation of EHP-5 and to provide better insight in quality of life consideration of women with endometriosis in Croatian clinical practice. A 150 consecutive patients with surgically proven endometriosis were enrolled. The translation to Croatian followed standardized procedure. Cronbach's Alpha was calculated to calculate internal consistency reliability of EHP-5. The test-retest reliability was calculated using intraclass correlation coefficient (ICC). The t test for independent samples was used to assess known-groups validity. RESULTS: Both EHP-5 core and EHP-5 modular parts of the questionnaire had good internal consistency, assessed by the Cronbach's Alpha coefficient (α = 0.793 and α = 0.842, respectively). Obtained results indicate very good reliability for core as well as for modular part of EHP-5 questionnaire (ICC = 0.896 and 0.936, respectively). The independent t test showed that women who reported their pain with VAS scale 7 or more had significantly higher results (p < 0.001) on EHP-5 (M = 50.63) compared with women who reported their pain 6 or less (M = 26.91). Furthermore, we found statistically significant difference between women who are infertile with women who are fertile (p < 0.001), whereby infertile women had higher average result on EHP-5 (M = 49.55) compared with fertile women (M = 34.36). CONCLUSIONS: The Croatian version of the EHP-5 have very good psychometric characteristics and can be used as a reliable tool for assessing patients with endometriosis in everyday clinical practice.

SUCCOR cone study: conization before radical hysterectomy.

OBJECTIVE: To evaluate disease-free survival of cervical conization prior to radical hysterectomy in patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009). METHODS: A multicenter retrospective observational cohort study was conducted including patients from the Surgery in Cervical Cancer Comparing Different Surgical Aproaches in Stage IB1 Cervical Cancer (SUCCOR) database with FIGO 2009 IB1 cervical carcinoma treated with radical hysterectomy between January 1, 2013, and December 31, 2014. We used propensity score matching to minimize the potential allocation biases arising from the retrospective design. Patients who underwent conization but were similar for other measured characteristics were matched 1:1 to patients from the non-cone group using a caliper width ≤0.2 standard deviations of the logit odds of the estimated propensity score. RESULTS: We obtained a weighted cohort of 374 patients (187 patients with prior conization and 187 non-conization patients). We found a 65% reduction in the risk of relapse for patients who had cervical conization prior to radical hysterectomy (hazard ratio (HR) 0.35, 95% confidence interval (CI) 0.16 to 0.75, p=0.007) and a 75% reduction in the risk of death for the same sample (HR 0.25, 95% CI 0.07 to 0.90, p=0.033). In addition, patients who underwent minimally invasive surgery without prior conization had a 5.63 times higher chance of relapse compared with those who had an open approach and previous conization (HR 5.63, 95% CI 1.64 to 19.3, p=0.006). Patients who underwent minimally invasive surgery with prior conization and those who underwent open surgery without prior conization showed no differences in relapse rates compared with those who underwent open surgery with prior cone biopsy (reference) (HR 1.94, 95% CI 0.49 to 7.76, p=0.349 and HR 2.94, 95% CI 0.80 to 10.86, p=0.106 respectively). CONCLUSIONS: In this retrospective study, patients undergoing cervical conization before radical hysterectomy had a significantly lower risk of relapse and death.

CTLA4-Linked Autoimmunity in the Pathogenesis of Endometriosis and Related Infertility: A Systematic Review.

Several studies, although with conflicting results, have sought to determine the concentration of soluble CTLA4 antigens in peripheral blood plasma and peritoneal fluid in patients with endometriosis-related infertility. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) through a search of the following databases: MEDLINE, EMBASE, Global Health, The Cochrane Library, Health Technology Assessment Database and Web of Science, and Clinical Trials research register. We included observational or prospective human and animal studies with any features related to endometriosis and/or infertility studies involving CTLA4-related pathogenesis published in English. The results of studies in which the size and characteristics of the observed groups were not stated were excluded. From the initial pool of 73 publications identified and screened, we finally included 5 articles to summarize the most recent knowledge about CTLA4-linked autoimmunity in the pathogenesis of endometriosis and related infertility. Evidence from clinical studies shows that CTLA4-based autoimmunity is involved in the maintenance of chronic inflammation in the peritoneal environment, with pre-clinical evidence of anti-CTLA antibodies as a potential novel target therapy for endometriosis. However, CTLA4 gene analyses do not support findings of CTLA4-linked autoimmunity as a primary determinant of the pathogenesis of endometriosis. These findings underlie the role of complex interactions within the family of immune checkpoint molecules involved. Further studies are needed to investigate the clinical relevance of anti-CTLA target therapy, taking into account the potential adverse events and repercussions of novel immunologic therapy modalities. However, with the general scarcity of studies investigating this topic, the clinical importance of CTLA4 autoimmunity still remains unclear.

Radical hysterectomy in early cervical cancer in Europe: characteristics, outcomes and evaluation of ESGO quality indicators.

INTRODUCTION: Comprehensive updated information on cervical cancer surgical treatment in Europe is scarce. OBJECTIVE: To evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database. METHODS: The SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified. RESULTS: The mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m2 (SD 4.9). A total of 423 (36.6%) patients had a previous cone biopsy. Tumor size (clinical examination) <2 cm was observed in 667 (57.7%) patients. The most frequent histology type was squamous carcinoma (794 (68.7%) patients), and positive lymph nodes were found in 143 (12.4%) patients. A total of 633 (54.8%) patients were operated by open abdominal surgery. Intra-operative complications occurred in 108 (9.3%) patients, and post-operative complications during the first month occurred in 249 (21.5%) patients, with bladder dysfunction as the most frequent event (119 (10.3%) patients). Clavien-Dindo grade III or higher complication occurred in 56 (4.8%) patients. A total of 510 (44.1%) patients received adjuvant therapy. After a median follow-up of 58 months (range 0-84), the 5-year disease-free survival was 88.3%, and the overall survival was 94.9%. In our population, 10 of the 11 surgical-related quality indicators currently recommended by ESGO were fully fulfilled 5 years before its implementation. CONCLUSIONS: In this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.

Maternity Blues among Croatian Mothers - A Single-Center Study.

BACKGROUND: Maternity blues is a transient change of mood that occurs within the first few days after delivery. Some of the most common symptoms include mood swings, tearfulness, irritability, loss of appetite, fatigue. The aim of the study was to investigate the relationship between maternity blues, psychological, demographic and obstetrics risk factors. SUBJECTS AND METHODS: A cross-sectional study was conducted between October 2019 and February 2020 at the University Hospital Center Zagreb, Croatia. Final analysis included 227 mothers. Participants were assessed with Stein's Maternity Blues Scale, Connor-Davidson Resilience Scale (CD-RISC), Multidimensional Scale of Perceived Support (MSPSS) and Brennan's Experiences in Close Relationship Scale, as well as demographic and obstetric data. RESULTS: The prevalence of maternity blues in our study was 19.9%. Higher result on Stein's Maternity Blues Scale was associated with anxious attachment style (r=0.425, p<0.01), oxytocin (r=0.308, p<0.01), lower birth weight (r=-0.242), lower resilience (r=-0.252) and less perceived social support from family and significant other (p<.01). CONCLUSIONS: This report presents the very first study assessing maternity blues occurence among Croatian mothers and in Croatian cultural environment. We believe that our report will address importance of employing adequate screening methods in preventing and timely recognizing maternity blues and subsequent postpartum depression in Croatian population.

SUCCOR study: an international European cohort observational study comparing minimally invasive surgery versus open abdominal radical hysterectomy in patients with stage IB1 cervical cancer.

BACKGROUND: Minimally invasive surgery in cervical cancer has demonstrated in recent publications worse outcomes than open surgery. The primary objective of the SUCCOR study, a European, multicenter, retrospective, observational cohort study was to evaluate disease-free survival in patients with stage IB1 (FIGO 2009) cervical cancer undergoing open vs minimally invasive radical hysterectomy. As a secondary objective, we aimed to investigate the association between protective surgical maneuvers and the risk of relapse. METHODS: We obtained data from 1272 patients that underwent a radical hysterectomy by open or minimally invasive surgery for stage IB1 cervical cancer (FIGO 2009) from January 2013 to December 2014. After applying all the inclusion-exclusion criteria, we used an inverse probability weighting to construct a weighted cohort of 693 patients to compare outcomes (minimally invasive surgery vs open). The first endpoint compared disease-free survival at 4.5 years in both groups. Secondary endpoints compared overall survival among groups and the impact of the use of a uterine manipulator and protective closure of the colpotomy over the tumor in the minimally invasive surgery group. RESULTS: Mean age was 48.3 years (range; 23-83) while the mean BMI was 25.7 kg/m2 (range; 15-49). The risk of recurrence for patients who underwent minimally invasive surgery was twice as high as that in the open surgery group (HR, 2.07; 95% CI, 1.35 to 3.15; P=0.001). Similarly, the risk of death was 2.42-times higher than in the open surgery group (HR, 2.45; 95% CI, 1.30 to 4.60, P=0.005). Patients that underwent minimally invasive surgery using a uterine manipulator had a 2.76-times higher hazard of relapse (HR, 2.76; 95% CI, 1.75 to 4.33; P<0.001) and those without the use of a uterine manipulator had similar disease-free-survival to the open surgery group (HR, 1.58; 95% CI, 0.79 to 3.15; P=0.20). Moreover, patients that underwent minimally invasive surgery with protective vaginal closure had similar rates of relapse to those who underwent open surgery (HR, 0.63; 95% CI, 0.15 to 2.59; P<0.52). CONCLUSIONS: Minimally invasive surgery in cervical cancer increased the risk of relapse and death compared with open surgery. In this study, avoiding the uterine manipulator and using maneuvers to avoid tumor spread at the time of colpotomy in minimally invasive surgery was associated with similar outcomes to open surgery. Further prospective studies are warranted.

Validation of the UDI-6 and the ICIQ-UI SF - Croatian version.

INTRODUCTION AND HYPOTHESIS: Despite the widespread use of UDI-6 and ICIQ-UI SF in Croatia, it remains unknown whether a realiable and valid measure for the population of interest is used. Thus, the aim of this study was to translate, adapt and validate the UDI-6 and the ICIQ-UI SF in Croatia. METHODS: The study included a total of 232 consecutive patients with urinary incontinence symptoms. The translation to Croatian followed standardized procedure. All participants underwent urodynamic assesment and completed UDI-6 and ICIQ-UI SF questionnaires at inclusion and 2 weeks after to assess test-retest reliability. Cronbach α coefficient was calculated in order to assess internal consistency. RESULTS: Both questionnaires had high internal consistency (Cronbach α for UDI-6 and ICIQ-UI SF was .83 and .85, respectively) and high test-retest reliability (intraclass correlation coefficient .99 for instruments). Strong correlation was found between urodynamic findings and total scores in UDI-6 and ICIQ-UI SF (ρ = 0.88 and 0.89, respectively). Women with stress urinary incontinence (SUI) and detrusor overactivity (DOA) group had significantly higher scores on UDI-6 (Mdn = 33.33 and Mdn = 50, respectively) compared to women with no urodynamic abnormality (Mdn = 0; p < 0.001). Women with no urodynamic abnormality scored significantly lower on ICIQ-UI SF (Mdn = 0; p < 0.001) compared to women with SUI (Mdn = 14) and DOA (Mdn = 16). Women with DOA scored worse on Irritative and Obstructive symptoms when comparing with two other groups (p < 0.001), while women with SUI had significantly worse score on Stress symptoms subscale (p < 0.001). CONCLUSIONS: The UDI-6 and ICIQ-UI SF have very good psychometric characteristics and can be used in Croatian urogynecology practice.

Fertility-sparing surgery for patients with malignant ovarian germ cell tumors: 10 years of clinical experience from a tertiary referral center.

PURPOSE: To describe a case series of patients with malignant ovarian germ cell tumors (MOGCT) treated exclusively with fertility-sparing surgery (FSS) with or without adjuvant chemotherapy. METHODS: We retrospectively reviewed the records of 27 patients with MOGCT treated in the Department of Obstetrics and Gynecology, University Hospital Center Zagreb, Croatia, between January 2009 and July 2019. RESULTS: The median age at diagnosis was 22 years, and the main symptom was abdominal distension (57.0%). The most prevalent histological subtype was immature teratoma (n = 13, 48.1%). Twenty-three patients (85.2%) had laparotomy and 4 (14.8%) had laparoscopy, without conversions. Lymphadenectomy was performed in 16 (59.3%) patients, with 184 removed lymph nodes, and omentectomy was performed in 19 (70.4%) patients. The rate of chemotherapy administration was 81.5%. The follow-up length ranged between 6.30 and 115.1 months (median: 49.60 months). No patient experienced tumor recurrence. The rate of complete gross resection was 100%. At the time of analysis, all patients were alive and disease free. Fifty percent of patients who actively tried to conceive after FSS became pregnant, with 12 deliveries. CONCLUSION: This study suggests that FSS is a safe treatment option for MOGCT, regardless of tumor stage and histological type.

Optimization of the monitoring of landfill gas and leachate in closed methanogenic landfills.

Monitoring of the gas and leachate parameters in a closed landfill is a long-term activity defined by national legislative worldwide. Serbian Waste Disposal Law defines the monitoring of a landfill at least 30 years after its closing, but the definition of the monitoring extent (number and type of parameters) is incomplete. In order to define and clear all the uncertainties, this research focuses on process of monitoring optimization, using the closed landfill in Zrenjanin, Serbia, as the experimental model. The aim of optimization was to find representative parameters which would define the physical, chemical and biological processes in the closed methanogenic landfill and to make this process less expensive. Research included development of the five monitoring models with different number of gas and leachate parameters and each model has been processed in open source software GeoGebra which is often used for solving optimization problems. The results of optimization process identified the most favorable monitoring model which fulfills all the defined criteria not only from the point of view of mathematical analyses, but also from the point of view of environment protection. The final outcome of this research - the minimal required parameters which should be included in the landfill monitoring are precisely defined.

Group assessment of key indicators of sustainable waste management in developing countries.

Decision makers in developing countries are struggling to solve the present problems of solid waste management. Prioritisation and ranking of the most important indicators that influence the waste management system is very useful for any decision maker for the future planning and implementation of a sustainable waste management system. The aim of this study is to evaluate key indicators and their related sub-indicators in a group decision-making environment. In order to gain insight into the subject it was necessary to obtain the qualified opinions of decision makers from different countries who understand the situation in the sector of waste management in developing countries. An assessment is performed by 43 decision makers from both developed and developing countries, and the applied methodology is based on a combined use of the analytic hierarchy process, from the multi-criteria decision-making set of tools, and the preferential voting method known as Borda Count, which belongs to social choice theory. Pairwise comparison of indicators is performed with the analytic hierarchy process, and the ranking of indicators once obtained is assessed with Borda Count. Detailed analysis of the final results showed that the Institutional-Administrative indicator was the most important one, with the maximum weight as derived by both groups of decision makers. The results also showed that the combined use of the analytic hierarchy process and Borda Count contributes to the credibility and objectivity of the decision-making process, allowing its use in more complex waste management group decision-making problems to be recommended.

Current Medical Strategies in the Prevention of Ovarian Hyperstimulation Syndrome

The purpose of this review is to analyze current medical strategies in the prevention of ovarian hyperstimulation syndrome (OHSS) during ovarian stimulation for in vitro fertilization. Owing to contemporary preventive measures of OHSS, the incidence of moderate and severe forms of the syndrome varies between 0.18% and 1.40%. Although none of medical strategies is completely effective, there is high-quality evidence that replacing human chorionic gonadotropin (hCG) by gonadotropin-releasing hormone (GnRH) agonists after GnRH antagonists and moderate- quality evidence that GnRH antagonist protocols, dopamine agonists and mild protocols reduce the occurrence of OHSS. Among various GnRH agonists, buserelin 0.5 mg, triptorelin 0.2 mg and leuprolide acetate (0.5-4 mg) have been mostly utilized. Although GnRH trigger is currently regarded as the best tool for OHSS prevention, intensive luteal support with exogenous administration of estradiol and progesterone or low-dose hCG on the day of oocyte retrieval or on the day of GnRH agonist trigger are required to achieve optimal conception rates due to early luteolysis. Among currently available dopamine agonists, cabergoline, quinagolide and bromocriptine are the most common drugs that should be used for prevention of both early and late OHSS. Mild stimulation protocols offer attractive option in OHSS prevention with satisfactory pregnancy rates.

Fertility in men with spinal cord injury.

Young men comprise the overwhelming majority of men with spinal cord injury (SCI), the incidence of which has been growing over the years. Due to advances in physical medicine and rehabilitation, remarkable improvements in survival rates have been reported, leading to life expectancies similar to those of the general population. However, many sexual and reproductive functions may be impaired due to erectile or ejaculatory dysfunction and semen abnormalities, characterised by low-sperm motility or viability in SCI males who have not become parents yet. Nevertheless, fatherhood is still possible through the introduction of specialised medical management, by using various medical, technical and surgical methods for sperm retrieval in combination with assisted reproductive techniques. Erectile dysfunction can be managed by the use of phosphodiesterase-5 inhibitors, intracavernosal injections, vacuum devices and penile prostheses. Semen can be obtained from the vast majority of anejaculatory men by medically assisted ejaculation through the use of penile vibratory stimulation or electroejaculation and via prostate massage or surgical procedures. Despite impaired sperm parameters, reasonable pregnancy rates similar to those in able-bodied subfertile cohorts have been reported. However, future research should focus on the optimisation of semen quality in these men and on improving natural ejaculation.

Financial implications of compliance with EU waste management goals: Feasibility and consequences in a transition country.

This paper outlines the approach that can assist decision makers to have first preliminary insights regarding costs of complying with requested European Union municipal waste management goals in transition and developing countries. Serbia, as a joining member of European Union, must confront itself with the challenges resulting from European Union waste management directives. Implementation of waste separation units and the construction of sanitary landfills is already in place in Serbia. However, new waste management practice will need additional transformation and will require implementation of waste treatment technologies for additional management of generated waste. Implementation of analyzed best available technology/techniques for waste treatment can support the country's effort in reaching the policy goals. However, the question here is how much will the implementation of additional waste treatments influence the overall waste management costs? Results of the scenario's financial viability show that composting and sanitary landfill are the most viable solutions regarding the costs, even under increasing discount rates. Although different discount rates influence the overall gate fees and net present values, the level of affordability for different scenarios remains the same.

Evaluation of key driver categories influencing sustainable waste management development with the analytic hierarchy process (AHP): Serbia example.

The problems of waste management have become increasingly complex in recent decades. The increasing amount of generated waste, adopted legislation in the field of waste management, administrative issues, economic impacts and social awareness are important drivers in achieving a sustainable waste management system. However, in practice, there are many other drivers that are often mutually in conflict. The purpose of this research is to define the precise driver and their corresponding sub-drivers, which are relevant for developing a waste management system and, on the basis of their importance, to determine which has the predominant influence on the slow development of a waste management system at the national and regional level, within the Republic of Serbia and similar countries of southeast Europe. This research presents two levels of decision making: the first is a pair-wise comparison of the drivers in relation to the goal and the second is a pair-wise comparison of the sub-drivers in relation to the driver and in relation to the goal. Results of performed analyses on the waste management drivers were integrated via the decision-making process supported by an analytic hierarchy process (AHP). The final results of this research shows that the Institutional-Administrative driver is the most important for developing a sustainable waste management system.

Municipal solid waste development phases: Evidence from EU27.

Many countries in the European Union (EU) have very developed waste management systems. Some of its members have managed to reduce their landfilled waste to values close to zero during the last decade. Thus, European Union legislation is very stringent regarding waste management for their members and candidate countries, too. This raises the following questions: Is it possible for developing and developed countries to comply with the European Union waste legislation, and under what conditions? How did waste management develop in relation to the economic development in the countries of the European Union? The correlation between waste management practices and economic development was analysed for 27 of the European Union Member States for the time period between 1995 and 2007. In addition, a regression analysis was performed to estimate landfilling of waste in relation to gross domestic product for every country. The results showed a strong correlation between the waste management variables and the gross domestic product of the EU27 members. The definition of the municipal solid waste management development phases followed a closer analysis of the relation between gross domestic product and landfilled waste. The municipal solid waste management phases are characterised by high landfilling rates at low gross domestic product levels, and landfilling rates near zero at high gross domestic product levels. Hence the results emphasize the importance of wider understanding of what is required for developing countries to comply with the European Union initiatives, and highlight the importance of allowing developing countries to make their own paths of waste management development.

Successful delivery of fetus with fetal inherited thrombophilia after two fetal deaths.

A pregnant woman with inherited thrombophilia (factor II mutation--20210A) had two late pregnancy losses. The first pregnancy was not well documented, but the second pregnancy was complicated by fetal thrombophilia and umbilical artery thrombosis, proven after fetal death. During the third pregnancy enoxaparine was introduced in the therapy and early amniocentesis was performed. Fetal thrombophilia was proven again. Early delivery was induced and performed with no complications, resulting in a live healthy infant. A history of miscarriages or recurrent fetal loss should raise suspicion of thrombophilia as a potential cause. It is debatable whether amniocentesis in pursuit of fetal thrombophilia should be performed and whether this will lead to a better perinatal outcome. When fetal thrombophilia is diagnosed, an earlier induction of delivery should be considered, taking into account the fetal extrauterine viability. The aforementioned approach of early delivery in cases of inherited fetal thrombophilia could be a possible solution for better perinatal outcomes.

Methane emissions from landfills in Serbia and potential mitigation strategies: a case study.

Open dumping and landfilling have represented the predominant method of waste management in Serbia during the past decades. This practice resulted in over 3600 waste disposal sites distributed all over the country. The locations of the sites and their characteristics have been determined in the framework of the presented study. The vast majority of disposal sites (up to 3300) are characterized by small deposition depth of waste and total waste volumes of less than 10,000 m(3). Only about 50 landfills in Serbia contain more than 100,000 m(3) of waste. These large landfills are responsible for more than 95% of the total CH(4) emissions from waste disposal, which was assessed as 60,000 tons of CH(4) in 2010. The evaluation of different measures [soil cover, compost cover and landfill gas (LFG) systems] for mitigating greenhouse gas emissions from Serbian landfills indicated that enhanced microbial CH(4) oxidation (using a compost cover), as well as the installation of LFG systems, could generate net revenues as saved CH(4) emissions are creditable for the European Greenhouse Gas Emissions Trading Scheme. In total between 4 and 7 million tons of CO(2) equivalent emissions could be avoided within the next 20 years by mitigating CH(4) emissions from Serbian landfills.
