RESUMEN

Magnetic resonance elastography (MRE) is an accurate noninvasive diagnostic tool for assessing the stiffness of parenchymal organs, including the spleen. However, this measurement may be biased due to postprandial changes in splenic stiffness. The aim of the current study was to evaluate postprandial changes in spleen stiffness assessed by MRE in a large sample of healthy volunteers. This was a prospective institutional research ethics board-approved study. Healthy volunteers with no history of liver disease were recruited for an MRE test and blood draw from December 2018 to July 2019. Each participant underwent spleen MRE after at least 4 h of fasting and again 30 min after a 1000 kcal meal. Also, 14 randomly selected volunteers underwent additional MRE examinations at 1.5 and 2.5 h after food intake. The MRE data were acquired at 60 Hz using a 1.5-T MRI scanner. The spleen stiffness was assessed using a weighted mean of stiffness values from regions of interest manually drawn on three to five spleen slices. Spearman's rank correlation, Wilcoxon signed-rank, Friedman, and Mann-Whitney tests were used for statistical analysis. A total of 100 volunteers met the inclusion criteria and were eventually enrolled in this study (age 23 ± 2 years; 65 women). The mean spleen stiffness for the whole group increased by 7.9% (p < 0.001) from the mean ± SD value of 5.09 ± 0.63 (95% CI: 4.96-5.21) kPa in the fasting state to 5.47 ± 0.66 (95% CI 5.34-5.60) kPa 30 min after the meal and then gradually decreased. However, even 2 h 30 min after the meal, the spleen stiffness was higher than in the fasting state. This difference was statistically significant at p less than 0.001. It was concluded that meal intake results in a statistically significant elevation of spleen stiffness that persists for 2.5 h. This finding supports the recommendation for routine fasting for more than 2.5 h prior to assessing MRE-based spleen stiffness.

RESUMEN

Few studies have evaluated cytokeratin's (CK) staining patterns in atypical endometrial hyperplasia (AEH) coexisting with early-stage endometrial cancer (EC). We aimed to assess the staining patterns of selected CKs (CK7, CK19, CK20, CK AE1/AE3) in 74 patients with coexisting AEH and EC by independently analyzing both morphological variables. Specimens were collected from women with AEH and EC who underwent surgical interventions between 2012 and 2019 at the Department of Obstetrics and Gynecology of Vilnius University Hospital "Santaros Klinikos" in Vilnius, Lithuania. Immunostaining was also qualitatively classified as being heterogeneous or intense. The results revealed heterogeneous CK7 expression in all AEH cases and intense staining in 95.95% cases of AEH. The heterogeneous expression of CK7 was detected in all EC specimens. Intense CK7 expression was observed in 95.09% cases of EC G1 and in all G2 ECs. Heterogenous CK19 expression was present in all AEH specimens with intense staining in 92.42% of cases. Heterogeneous CK19 expression was observed in all EC samples with intense expression in 86.27% cases of EC G1 and 100% cases of EC G2. Interestingly, a significant relationship was found when comparing the heterogeneous expression of CK19 between AEH and well-differentiated EC. A significant difference was reported in the intense expression of CK AE1/AE3 (p = 0.031; p = 0.029) between AEH and G2 ECs and in the intense expression of CK AE1/AE3 between G1 and G2 ECs. CK20 staining was not a characteristic feature for AEH and early-stage EC. CK staining is present either in AEH or in early-stage endometrioid-subtype EC in different manners. Heterogeneous CK19 expression was significantly more common in AEH than in EC. CK20 expression was not associated with either AEH nor early-stage EC. An intense expression of CK AE1/AE3 was mainly present in moderately differentiated ECs, whereas the intense reactivity of AE1/AE3 showed a significant difference in well to moderately differentiated uterine tumors. The clinical implication of CK staining may aid in the more accurate diagnosis of AEH and early-stage EC as well as detect micrometastases leading to better oncological outcomes.

RESUMEN

INTRODUCTION: Uterine leiomyomas are the most common neoplasm of the uterus in women. Massive lymphocytic infiltration in a myoma is an unusual finding. It is characterised by the varying intensity of lymphocyte infiltration, the presence of scattered plasma cells, eosinophilia, and rarely, other items. We would like to call attention to such a rare lesion. CASE DESCRIPTION: We present the case of a 31-year-old woman who had undergone surgical excision of a uterine tumour. Grossly, it had the typical uterine smooth muscle wall consistency. The microscopic examination revealed leiomyoma with heavy infiltration composed mainly of lymphocytes. On immunohistochemistry, in the lymphocytic infiltrate the T mature (CD3+/CD5+/TdT-) lymphocytes, small and of cytotoxic (CD8+/CD56-) type, prevailed, with moderate proliferative activity (expression of Ki67 found in ca. 30-40% of the cells), whereas B lymphocytes (CD20+/CD5-/TdT-) were innumerous and present in nodular aggregates. Despite a strong suspicion of neoplastic lymphoproliferation, the histopathological diagnosis was: leiomyoma with massive lymphoid infiltration. The cause of this feature is not known, although the gonadotropin-releasing hormone agonist and post-menopausal processes may promote such transformations. In differential diagnosis, malignant lymphoma, inflammatory pseudotumour, and pyomyoma should be included. CONCLUSIONS: Lymphocytic infiltration within the uterine myoma is rare. The recognition of its distinct histological features is important to avoid possible misdiagnosis.

RESUMEN

OBJECTIVE: We assessed the prognostic factors related to 10-year overall survival and disease-free survival in cervical cancer patients that underwent primary surgical protocols in 1 institution. MATERIALS AND METHODS: A total of 102 patients with uterine cervical cancer at FIGO stages IA2-IIB that underwent a Piver type III radical hysterectomy and pelvic lymphadenectomy between 1998 and 2001 were included. Univariate and multivariate analyses of 10-year overall survival and 10-year disease-free survival were performed. RESULTS: Univariate analysis revealed that only lymphovascular space invasion significantly affected 10-year overall survival (p = 0.04), but it had no effect on the 10-year disease-free survival rate. Multivariate analysis demonstrated that survival rates were significantly affected by FIGO stage (p = 0.02, 95% CI: 1.18-5.55, for 10-year overall survival; p = 0.03, 95% CI: 1.07-6.12, for 10-year disease-free survival) and metastases to the pelvic lymph nodes (p = 0.0005, 95% CI: 1.81-8.53, for 10-year overall survival; p = 0.01, 95% CI: 1.26-7.24, for 10-year disease-free survival). CONCLUSIONS: The only independent prognostic factors for 10-year survival rates in patients with cervical cancer at FIGO stages IA2-IIB were clinical stage and presence of metastases to the pelvic lymph nodes. The presence of lymphovascular space invasion adversely affected 10-year overall survival.

RESUMEN

BACKGROUND: Computational intelligence methods, including non-linear classification algorithms, can be used in medical research and practice as a decision making tool. This study aimed to evaluate the usefulness of artificial intelligence models for 5-year overall survival prediction in patients with cervical cancer treated by radical hysterectomy. METHODS: The data set was collected from 102 patients with cervical cancer FIGO stage IA2-IIB, that underwent primary surgical treatment. Twenty-three demographic, tumor-related parameters and selected perioperative data of each patient were collected. The simulations involved six computational intelligence methods: the probabilistic neural network (PNN), multilayer perceptron network, gene expression programming classifier, support vector machines algorithm, radial basis function neural network and k-Means algorithm. The prediction ability of the models was determined based on the accuracy, sensitivity, specificity, as well as the area under the receiver operating characteristic curve. The results of the computational intelligence methods were compared with the results of linear regression analysis as a reference model. RESULTS: The best results were obtained by the PNN model. This neural network provided very high prediction ability with an accuracy of 0.892 and sensitivity of 0.975. The area under the receiver operating characteristics curve of PNN was also high, 0.818. The outcomes obtained by other classifiers were markedly worse. CONCLUSIONS: The PNN model is an effective tool for predicting 5-year overall survival in cervical cancer patients treated with radical hysterectomy.

RESUMEN

Carcinosarcomas (CSs; malignant mixed Müllerian tumors) of the uterus are highly malignant neoplasms characterized by an unfavorable outcome. They represent less than 5% of all uterine malignancies, and the median patient survival rate is only 21 months. p53 pathway alterations have been studied in CSs originating from the uterus, supporting the monoclonal nature of most but not all of these neoplasms. This paper gives an overview of the current knowledge of p53 pathway distortions in patients with uterine CSs. The survival of patients with uterine CSs in relation to p53 pathway alterations is also briefly summarized.

RESUMEN

BACKGROUND: Magnetic resonance elastography (MRE) is a rapidly developing medical imaging technique that allows for quantitative assessment of the biomechanical properties of the tissue. MRE is now regarded as the most accurate noninvasive test for detecting and staging liver fibrosis. A two-dimensional (2D MRE) acquisition version is currently deployed at >2000 locations worldwide. 2D MRE allows for the evaluation of the magnitude of the complex shear modulus, also referred to as stiffness. The development of 3D vector MRE has enabled researchers to assess the biomechanical properties of small organs where wave propagation cannot be adequately analyzed with the 2D MRE imaging approach used in the liver. In 3D vector MRE, the shear waves are imaged and processed throughout a 3D volume and processed with an algorithm that accounts for wave propagation in any direction. Additionally, the motion is also imaged in x, y, and z directions at each voxel, allowing for more advanced processing to be applied. PURPOSE: This review describes the technical principles of 3D vector MRE, surveys its clinical applications in small organs, and discusses potential clinical significance of 3D vector MRE. CONCLUSION: 3D vector MRE is a promising tool for characterizing the biomechanical properties of small organs such as the uterus, pancreas, thyroid, prostate, and salivary glands. However, its potential has not yet been fully explored.

RESUMEN

Introduction: Infertility has been diagnosed in millions of people around the world and is described as a complex medical, mental, and social problem that affects many aspects of life. The aim of the study was to extract the determining factors and the level of self-esteem and the degree of acceptance of the disease in infertile patients and to find differences between women and men in this aspect. Methods: A total 456 patients (235 women and 221 men) from infertile couples participated in a cross-sectional study. To collect data a Personal Information Form (PIF), Rosenberg Self-Esteem Scale (SES), and Acceptance of Illness Scale (AIS) were used. Results: The overall self-esteem score for the whole sample was 30.50 (15 ± 30) points and for acceptance of the disease 32.4 (8 ± 40) points. In the study group, men obtained a slightly higher level of self-esteem than women (31.00 vs. 30.04 points). Additionally, men had a higher level of acceptance of the disease (33.12 vs. 31.80) than women. Socio-demographic factors such as age and level of education had impact on scores SES and AIS. Clinical factors did not determine the results of SES and AIS, both in the overall sample and in the female and male groups. Conclusion: Self-esteem in patients from infertile couples increases with age and level of education. There are also significant differences between women and men, i.e., positive correlations between the level of education and self-esteem in men and the degree of acceptance of the disease in women.

RESUMEN

Uterine fibromas are the most common benign uterine tumors. Although the majority of leiomyomas remain asymptomatic, they can cause serious clinical problems, including abnormal uterine bleeding, pelvic pain, and infertility, which require effective gynecological intervention. Depending on the symptoms as well as patients' preferences, various treatment options are available, such as medical therapy, non-invasive procedures, and surgical methods. Regardless of the extent of the surgery, the preferred option is the laparoscopic approach. To reduce the risk of spreading occult malignancy and myometrial cells associated with fragmentation of the specimen before its removal from the peritoneal cavity, special systems for laparoscopic contained morcellation have been developed. The aim of this review is to present the state-of-the-art contained morcellation. Different types of available retrieval bags are demonstrated. The advantages and difficulties associated with contained morcellation are described. The impact of retrieval bag usage on the course of surgery, as well as the effects of the learning curve, are discussed. The role of contained morcellation in the overall strategy to optimize patient safety is highlighted.

RESUMEN

PURPOSE: Magnetic resonance elastography (MRE) has been established as the most accurate noninvasive technique for diagnosing liver fibrosis. Recent publications have suggested that the measurement of splenic stiffness is useful in setting where portal hypertension may be present. The goal of the current study was to compile normative data for MRE-assessed stiffness measurements of the spleen in young adults. MATERIALS AND METHODS: A total of 100 healthy young Caucasian volunteers (65 females and 35 males) in the age range of 20 to 32 years were enrolled in this study. The participants reported no history of chronic spleen and liver disease, normal alcohol consumption, and a normal diet. The MRE data were acquired by using a 1.5 T whole-body scanner and a 2D GRE pulse sequence with 60 Hz excitation. Spleen stiffness was calculated as a weighted mean of stiffness values in the regions of interest manually drawn by the radiologist on three to five spleen slices. RESULTS: Mean spleen stiffness was 5.09 ± 0.65 kPa for the whole group. Male volunteers had slightly higher splenic stiffness compared to females: 5.28 ± 0.78 vs. 4.98 ± 0.51 kPa, however, this difference was not statistically significant (p = 0.12). Spleen stiffness did not correlate with spleen fat content and liver stiffness but a statistically significant correlation with spleen volume was found. CONCLUSIONS: The findings of this study provide normative values for 2D MRE-based measurement of spleen stiffness in young adults, a basis for assessing the value of this biomarker in young patients with portal system pathologies.

RESUMEN

Tubal diseases account for 25-40% of female factor infertility. Mainly, they involve the distal part of the fallopian tube, and hydrosalpinx is the most severe manifestation. Usually, the management decision is made between reconstructive surgery and ART, depending on the severity of the tubal damage, patient age, ovarian reserve, and seminogram, as well as financial, religious, ethical, and psychological factors. Estimated live-birth rates after corrective surgery range from 9% to 69%. The success rate of IVF is about 30% live-birth rate per cycle initiated in women across all ages with tubal factor infertility. Surgery offers a long-term cure and patients may attempt conception many times but are burdened with perioperative adverse events. IVF bypasses potential complications of operative treatment; however, this has its own unique risks. The effectiveness of reconstructive surgery versus ART has not been adequately evaluated. The success of fertility management depends on a thorough interpretation of existing data and careful patient selection. The presented review provides updates on the most recent progress in this area.

RESUMEN

OBJECTIVES: Morcellation is an integral part of laparoscopic procedures related to uterine fibroids, which consist of the mechanical fragmentation of the tumor and its extraction outside the abdominal cavity. To avoid the risk of tissue dissemination, special extraction systems have been developed, which allow morcellation of the specimen under visual control and its removal without contact with the abdominal organs. The aim of the paper is to compare the two systems for laparoscopic morcellation. MATERIAL AND METHODS: The study included 33 premenopausal women with symptomatic leiomyomas or adenomyosis, who were qualified for laparoscopic surgery with contained power morcellation. Patients were allocated alternately to a different tissue extraction system's group. According to the study protocol, selected operative parameters were prospectively recorded. Finally, an assessment of bag use was performed. The data was statistically analyzed. RESULTS: There were significant differences between the two tested systems in terms of introducing and positioning the bag, its removal from the peritoneal cavity, as well as optic trocar insertion and establishing the pseudo-peritoneum. CONCLUSIONS: Despite the minor design differences and some ergonomic aspects, both presented systems proved to be safe and feasible tools for laparoscopic contained morcellation. This technique both reduces the risk of tissue dissemination and preserves the advantages of minimal invasiveness.

RESUMEN

The aim of the study was to evaluate the level of life satisfaction and health behaviors presented by patients with diagnosed infertility. This cross-sectional study included 456 patients (235 women and 221 men) from infertile couples in southeastern Poland from June 2019 to February 2020. Participants completed a questionnaire on sociodemographic characteristics, the Health Behaviors Inventory (HBI), and the Satisfaction with Life Scale (SWLS). The average score of severity of health behaviors for the study group was 82.96 points. Satisfaction with life at a higher level was declared by 57.6% of respondents, at an average level was declared by 31.4%, and at a lower level was declared by 11%. The SWLS score for the entire study group was 24.11 points (6.82 points on the sten scale). Respondents who achieved a higher rate of life satisfaction also had a higher level of severity of health behaviors (p < 0.0001). There were no significant differences between male and female SWLS scores, although the women had significantly higher rates of severity of health behaviors than men. The level of health behavior is positively related to life satisfaction in infertile patients. Medical personnel should conduct health education on a healthy lifestyle that promotes the improvement of reproductive health.

RESUMEN

The term personalized medicine was created for oncological patients, but due to its positive clinical results it is now used in many other fields of medicine, including reproductive medicine. The aim of the study was to determine the level of stress and strategies of coping with stress in patients treated for infertility. The study-using a questionnaire developed by the authors, the Perceived Stress Scale-10 (PSS-10), and the Coping Orientation to Problems Experienced Inventory (Mini-COPE)-was conducted among 456 people from infertile couples. Conclusions: More than half of the studied patients demonstrated a high level of stress. The choice of coping strategies was related to the respondents' gender and level of stress as well as their experience with assisted reproductive technology.

RESUMEN

Magnetic resonance elastography (MRE) is a reliable noninvasive method for assessment of hepatic stiffness. Liver stiffness is known to be affected by elevated postprandial portal blood flow in patients with chronic liver disease. The goal of this study was to determine whether food intake affects liver stiffness in the absence of known liver disease. We evaluated 100 volunteers (35 men and 65 women) who met inclusion criteria. The subjects had two MRE examinations, first while fasting and then 30 min after a test meal. Fourteen subjects also had two additional MRE exams 1 h 30 min and 2 h 30 min after the meal. Liver stiffness was measured by placing the largest possible polygon ROIs on the four widest liver slices and calculated as a mean of stiffness values from each slice. The correlation of liver stiffness values before and after the meal was assessed using a paired t-test. To evaluate the relationship between the change in postprandial liver stiffness and fasting liver stiffness values, linear regression was performed. The liver stiffness values in the fasting state ranged from 1.84 to 2.82 kPa, with a mean of 2.30 ± 0.23 kPa (95% CI 2.25-2.34). At 30 min after the meal, liver stiffness values ranged from 2.12 to 3.50 kPa, with a mean of 2.70 ± 0.28 kPa (95% CI 2.64-2.75), demonstrating a systematic postprandial increase by 0.40 ± 0.23 kPa (17.7 ± 3.5%). Meal intake significantly increases liver stiffness in healthy individuals, which persists for at least 2 h 30 min. Patients should fast for 3-4 h before MRE examinations to avoid fibrosis overstaging due to postprandial liver stiffness augmentation.

RESUMEN

OBJECTIVES: Alterations of p53 pathway (p14(ARF)/MDM2/p53) play a crucial role in the development and progression of various human neoplasms, including endometrial carcinoma (EC). The aim of the current research was to examine the p14(ARF) expression pattern in primary ECs and corresponding metastatic lesions. MATERIALS AND METHODS: We studied 47 primary ECs and corresponding metastatic lesions applying immunohistochemistry and investigated the relationship between p14(ARF) overexpression and clinicopathological variables of carcinoma as well as TP53 alterations. RESULTS: Protein expression was predominantly nuclear, present in 32 (68%) of 47 primary cases and in 28 (60%) of 47 metastatic lesions. There were seven p14(ARF)-positive primary tumors showing negative reactivity in the metastatic lesions. On the other hand, 3 cases lacked protein immunoreactivity in the primary ECs but revealed weak nuclear staining in the corresponding metastases. A case of primary cervical adenocarcinoma metastasizing to the lymph nodes showed p14(ARF) expression both in the primary tumor and the corresponding metastases. A trend was found between the p14(ARF) expression in primary tumors and the presence of the neoplasms in the fallopian tube (P = 0.063), but none of the other clinicopathological variables of carcinoma was related to protein immunoreactivity in advanced-stage uterine neoplasms. The p14(ARF) expression in EC metastases was related to the presence of the primary tumor in the fallopian tube (P = 0.036). The p14(ARF) expression was not associated with unfavorable outcome both in the primary tumors (P = 0.302) and in the corresponding metastases (P = 0.217). There was also no relationship between the p14(ARF) expression pattern and TP53 pathway alterations. CONCLUSIONS: Altogether, the p14(ARF) protein is expressed in more than half of the primary ECs and metastatic lesions analyzed and is associated with the transtubal dissemination of the primary tumor. The pattern of the p14(ARF) expression is not associated with the alterations of other TP53 pathway members in advanced-stage human ECs.

Iron overload is a relatively common clinical condition resulting from disorders such as hereditary hemochromatosis, thalassemia, sickle cell disease, and myelodysplasia that can lead to progressive fibrosis and eventually cirrhosis of the liver. Therefore, it is essential to recognize the disease process at the earliest stage. Liver biopsy is the reference test for the assessment of liver fibrosis. It also allows for quantifying liver iron concentration (LIC) in patients. However, this is an invasive method with significant limitations and possible risks. Magnetic resonance imaging (MRI) and evaluation of the R2* relaxation rate can be an alternative to biopsy for assessing LIC. However, it causes a need for accurate R2* data corresponding to standard value for further comparison with examined patients. This study aimed to assess the normative values of liver R2* in healthy individuals. A total of 100 volunteers that met established criteria were enrolled in the study: 36 (36%) men and 64 (64%) women. The mean age was 22.9 years (range 20 to 32 years). R2* was estimated by an MRI exam with a 1.5 T clinical magnetic resonance scanner. Images for measuring the LIC and liver fat concentration were obtained using the IDEAL-IQ technique for liver imaging. The Mean (SD) liver R2* was 28.34 (2.25) s-1 (95% CI, 27.78-28.90, range 23.67-33.00 s-1) in females, 29.57 (3.20) s-1 (95% CI, 28.49-30.66, range 23.93-37.77 s-1) in males, and 28.72 (2.69) s-1 (range 23.67-37.77 s-1) in the whole group. R2* value in this particular population with a high proportion of young women did not exceed 38 s-1. In the absence of fibrosis or steatosis, liver stiffness and fat fraction did not show any relationship with R2*.

RESUMEN

OBJECTIVES: To evaluate magnetic resonance elastography as a tool for characterizing uterine leimyomas. MATERIAL AND METHODS: At total of 12 women with symptomatic leiomyomas diagnosed in physical and ultrasound examinations were enrolled in this pilot study. Before surgery, all patients underwent magnetic resonance elastography of the uterus using a 1.5 T MR whole-body scanner (Optima, GE Healthcare, Milwaukee, WI, USA). Surgical specimens were forwarded for histological examination. The findings were allocated into 3 categories depending on the percentage content of connective tissue: below 15%, from 15 to 30% and more than 30%. The median stiffness of leiomyomas for each of the group was calculated. The U-Mann Whitney test was used for statistical analysis. RESULTS: The stiffness of the leiomyomas ranged between 3.7-6.9 kPa (median value 4.9 kPa). The concentration of extracellular components in the leiomyomas did not exceed 40%. An increasing trend of the stiffness with the growing percentage of extracellular component was observed. Stiffness of the leiomyomas obtained by MRE varies depending on microscopic composition. CONCLUSIONS: The value of stiffness shows a trend of increasing with the percentage of extracellular component of the leiomyoma. Further studies are required to assess the usefulness of MRE in diagnostics of uterine leiomyomas.

RESUMEN

BACKGROUND: Endometrial cancer is the most common malignant neoplasm of the female reproductive organs. A dysfunctional endometrial renin-angiotensin system (RAS) might contribute to the growth and spread of endometrial cancer. The RAS-related gene polymorphisms, including the polymorphism of insertion/deletion (I/D) in the angiotensin-converting enzyme (ACE) gene, influence RAS activity. OBJECTIVES: In the present study, we examined the association between the I/D polymorphism of the ACE gene and endometrial cancer risk in Polish women. MATERIAL AND METHODS: Genotype analysis of the ACE I/D polymorphism was carried out using polymerase chain reaction (PCR) on 142 endometrial cancer type 1 patients and 68 cancer-free subjects. The results of the analyses were correlated with clinical data. RESULTS: The frequency of DD, DI and II ACE genotypes did not vary significantly between the experimental group and the control group (40 (28%), 61 (43%) and 41 (29%) vs 18 (26%), 31 (46%), and 19 (28%), respectively; p = 0.935). In addition, the incidence of the DD, DI and II polymorphisms in the ACE gene did not vary significantly between the experimental subgroups when stratified by cancer grade - G1, G2 and G3 endometrioid carcinoma - and the control group. Furthermore, the ACE polymorphism was not significantly associated with hypertension, diabetes or lymph node metastasis. CONCLUSIONS: The ACE I/D gene polymorphism was not associated with endometrial cancer risk or the clinicopathological features in Polish women.
