RESUMO

Selenium (Se) and manganese (Mn) are essential micronutrients that are important elements of cell metabolism. They are involved in the composition of enzyme systems and regulate enzyme activity. Disturbances in the homeostasis of these micronutrients affect the development of many diseases and carcinogenesis, which can be linked to increased levels of oxidative stress and impaired antioxidant properties of many enzymes. Selenium has a very important function in maintaining immune-endocrine, metabolic and cellular homeostasis. Manganese, on the other hand, is important in development, digestion, reproduction, antioxidant defense, energy production, immune response and regulation of neuronal activity. We review the role of selenium and manganese and their effects on tumor growth, metastasis potential and remodeling of the microenvironment. We also describe their role as potential biomarkers in the diagnosis and the potential for the use of Se- and Mn-containing compounds in composition for the treatment of cancer of the reproductive organs.

RESUMO

Neuroendocrine tumours of the gastrointestinal tract are rare. The incidence has increased in recent years due to improvements in diagnostic methods for detecting these lesions. These tumours have a poor prognosis, especially when detected at an advanced stage. The basis of the treatment is resection, and non-surgical treatments are also standard in the treatment process. The situation is similar in even rarer neuroendocrine tumours of the reproductive tract, which are associated with an equally poor prognosis. In this article, we focus on learning about the risk factors (including genetic mutations) that increase the risk of the disease and comparing the effectiveness of non-surgical treatments-chemotherapy, radiotherapy, peptide receptor radionuclide therapy, somatostatin analogues, and immunotherapy. The efficacy of these treatments varies, and immunotherapy appears to be a promising form of treatment; however, this requires further research.

RESUMO

This systematic review was conducted to gather evidence of preeclampsia occurring before the 20th week of gestation, additionally considering the role of PLGF and sFlt-1 in the development of the disease. In the three cases of preeclampsia before the 20th week of gestation presented in the authors' material, all pregnancies ended up with IUFD, and the SFlt-1/PLGF ratios were significantly elevated in all women. Eligible publications were identified with searches in the PubMed, Embase, Scopus, and Web of Science databases. No date or language restrictions were made. All original peer-reviewed scientific reports were included. A total of 30 publications were included in the final report, including case reports and case series. No other publication types regarding this issue were identified. In the literature, 34 cases of preeclampsia with onset occurring before the 20th week of gestation were identified, for a final total of 37 cases. Live births were reported in 5 cases (10.52%), and there were 9 intrauterine fetal demises (24.32%), and 23 terminations of pregnancy (62.16%). Preeclampsia before the 20th week of gestation is rare but can occur. We collected all available evidence regarding this phenomenon, with 37 cases reported worldwide. We call for large-scale cohort or register-based studies to establish revised definitions or develop new ones regarding the currently unrecognized very early onset preeclampsia.

RESUMO

Endometrial cancer is one of the most common gynecological malignancies, yet the molecular mechanisms that lead to tumor development and progression are still not fully established. Matrix metalloproteinases (MMPs) are a group of enzymes that play an important role in carcinogenesis. They are proteases involved in the degradation of the extracellular matrix (ECM) that surrounds the tumor and the affected tissue allows cell detachment from the primary tumor causing local invasion and metastasis formation. Recent investigations demonstrate significantly increased metalloproteinase and metalloproteinase inhibitor levels in patients with endometrial cancer compared to those with normal endometrium. In this review, we aim to show their clinical significance and possible use in the diagnosis and treatment of patients with endometrial cancer. We have critically summarized and reviewed the research on the role of MMPs in endometrial cancer.

RESUMO

Abnormally accelerated, premature placental senescence plays a crucial role in the genesis of pregnancy pathologies. Abnormal growth in the third trimester can present as small for gestational age fetuses or fetal growth restriction. One differs from the other by the presence of signs of placental insufficiency and the risk of stillbirth. The majority of stillbirths occur in normally grown fetuses and are classified as "unexplained", which often leads to conclusions that they were unpreventable. The main characteristic of aging is a gradual decline in the function of cells, tissues, and organs. These changes result in the accumulation of senescent cells in mitotic tissues. These cells begin the aging process that disrupts tissues' normal functions by affecting neighboring cells, degrading the extracellular matrix, and reducing tissues' regeneration capacity. Different degrees of abnormal placentation result in the severity of fetal growth restriction and its sequelae, including fetal death. This review aims to present the current knowledge and identify future research directions to understand better placental aging in late fetal growth restriction and unexplained stillbirth. We hypothesized that the final diagnosis of placental insufficiency can be made only using markers of placental senescence.

RESUMO

Prematurity has been one of the greatest challenges faced by perinatal medicine for many years. The recommended therapy for women with threatened preterm labor at 24 to 34 weeks' gestation is a single course of glucocorticoids. The greatest benefits have been proven when labor occurs at least 24 hours, but no later than 7 days after steroid administration. Applied treatment is not without influence on neonates' development. AIM: The aim of this study is to analyze the time between the administration of a course of glucocorticoids to patients with threatened preterm labor between 24 and 34 weeks of gestation and labor. MATERIALS AND METHODS: 459 deliveries by patients between 24 and 34 weeks' gestation who had received betamethasone (two 12 mg doses) or dexamethasone (four 6 mg doses) were analyzed. Their indications for glucocorticoid therapy were divided into four categories: the signs of threatened preterm labor, premature rupture of membranes, iatrogenic prematurity and cervical incompetence. The neonates (n=530) were divided into two main groups: group 1 of those born within the first 7 days (n1=127) and group 2 of those born more than 7 days (n2=403) after the glucocorticoids therapy. Statistical analysis was performed using the Statistica 13.3 software with calculations performed using the Mann- Whitney U and χ2 tests, assuming the level of statistical significance of <0.05 (p<0.05). RESULTS: The neonates born within the first 7 days after the glucocorticoid therapy accounted for 23.96% (127 children). The average time of delay between the course of glucocorticoids and labor was 33 days, with the longest interval being 116 days. The most common indications for glucocorticoids were iatrogenic causes in group 1 (35.40%) and the signs of threatened preterm labor (67.63%) in group 2. CONCLUSIONS: The percentage of births at the recommended time after steroidotherapy (not later than 7 days) was lower than expected. The prenatal steroid therapy qualification methods, should be reanalyzed, especially when signs of preterm labor are observed.

RESUMO

BACKGROUND: Since more than two decades Risk-reducing salpingo-oophorectomy (RRSO) is recommended and widely accepted by BRCA1/2 carriers as a method reducing ovarian cancer risk and improving survival rate. After RRSO, there remains a risk of breast cancer and peritoneal cancer. The characteristics of these neoplasms are not well known. In this study, we determined the selected parameters such as age at cancer diagnosis, time from RRSO to the diagnosis of cancer, and significance of BRCA1 mutation type in patients diagnosed with breast or peritoneal cancer during postoperative follow-up. METHODS: The material comprised of 195 BRCA1 carriers who performed RRSO between years 1999-2012. In this period, 16 patients developed cancer (6-primary breast cancer, 3-contralateral breast cancer, 5-relapse of breast cancer, 2-peritoneal cancer). They were subject of the further analysis. RESULTS: During the follow-up period mean age of patients after RRSO at the time of cancer diagnosis was 53.19. The mean age of patients diagnosed with primary breast cancer was 50, contralateral breast cancer - 58.67, recurrence of breast cancer - 51 and peritoneal cancer 60. The mean time periods from RRSO to the diagnosis of primary, contralateral, recurrence breast cancer were 53, 58.67 and 25,4 months respectively and of peritoneal cancer 46 months. BRCA1 c.5266dupC mutation carriers demonstrated significantly shorter time of cancer development compared to patients carrying c.181T > G and c.4035delA mutations. Peritoneal cancer was only observed in two c.181T > G BRCA1 mutation carriers. CONCLUSIONS: The mean age of cancer diagnosis and the mean time periods from RRSO to the diagnosis of cancer are similar to those observed by other researchers. The carriers of c.181T > G and c.5266dupC BRCA1 mutation should be the subject further studies in context of breast and peritoneal cancer risk or time of cancer development after RRSO, respectively.

RESUMO

Background Soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) are used as markers of preeclampsia. The aim of this paper was to assess the correlations between the sFlt-1/PlGF ratio values within the <38, 38-85 and >85 brackets and perinatal outcomes in pregnancies that require determination of these markers. Methods A total of 927 pregnant patients between 18 and 41 weeks' gestation suspected of or confirmed with any form of placental insufficiency (preeclampsia, intrauterine growth restriction [IUGR], gestational hypertension, HELLP syndrome, placental abruption) were included in the study. In each of the patients, the sFlt-1/PlGF ratio was calculated. Patients were divided into three groups according to the sFlt-1/PlGF ratio brackets of <38, 38-85 and >85. Results Significantly worse perinatal outcomes were found in the sFlt-1/PlGF >85 group, primarily with lower cord blood pH, neonatal birth weight and shorter duration of gestation. Statistically significant correlations between the values of these markers and the abovementioned perinatal effects were found. Conclusion An sFlt-1/PlGF ratio value of >85 suggests that either preeclampsia or one of the other placental insufficiency forms may occur, which is associated with lower cord blood pH, newborn weight and earlier delivery. Determining the disordered angiogenesis markers and calculating the sFlt-1/PlGF ratio in pregnancies complicated by placental insufficiency may lead to better diagnosis, therapeutic decisions and better perinatal outcomes.

RESUMO

AIM OF THE STUDY: An ERAS protocol provides the latest perioperative care principles, whose primary aim is to reduce complication rates, and therefore mortality. The aim of this study is to establish the progress of the ERAS pathway implementation in our gynaecology department. MATERIAL AND METHODS: This was a retrospective analysis of two sets of 100 consecutive medical records: patients treated before (PRE-ERAS) and after (ERAS) introduction of the ERAS protocol. All patients were comparable and all underwent major gynaecological surgery. Patients as well as medical and nursing staff were informed about the proposed preparation, surgical management and postoperative routine. RESULTS AND CONCLUSIONS: Patients were given supper and drank water during the night. Laparoscopic surgery was used in 44% and spinal anaesthesia was given for open surgery in 43 study patients. Use of drains was reduced only by 23%, bowel preparation by 15%. Intravenous fluid administration was reduced by 22%. Use of postoperative morphine was minimised to 12 patients. Postoperative nausea was managed with the regular use of anti-emetics. Anti-coagulation was given to 80% of the study group. Difficulties in the introduction of the ERAS protocol were due to refusal by some patients to mobilise and eat early postoperatively. Patients in the ERAS programme group were discharged earlier.Further information about the ERAS protocol in the media would facilitate patients' education among conservative society. In order to introduce new and innovative treatment methods, one has to take into account the cultural and ideological factors, especially when patient involvement is essential.

RESUMO

After several years of research, HE4 was found to be characterized by slightly worse sensitivity but significantly higher specificity as compared with CA125. Further studies led to the diagnostic potential of both markers (CA125 and HE4) being combined in a single risk of malignancy algorithm (ROMA) algorithm. The objective of this study was to assess the diagnostic capabilities of the ROMA algorithm using age ranges instead of dichotomization of patients according to the pre- and postmenopausal status. A total of 413 female patients were included in the study, including 162 premenopausal and 251 postmenopausal women. Calculation of the final ROMA values was achieved by means of stepwise reduction of coefficients in the proposed formula of: %ROMA = exp(PI)/[1-exp(PI)]*100) and PI = A + W(HE4)(*)ln(HE4) + W(CA125)(*)ln (CA125) and the arrangement of values with consideration to the age group, HE4 level, differentiation of modification, and directional coefficients as well as determination of individual deviations affecting the widening of the median. The cutoff value of modified algorithm ROMA P for the entire study population was calculated from receiver operating characteristic (ROC) curve and DeLong method at the levels of 23.5 %. Marked higher sensitivity and negative predictive value (NPV) values are observed for the standard ROMA algorithm while higher specificity and positive predictive value (PPV) values are observed for the modified algorithm ROMA P. The proposed age-related modification of algorithm calculation does not require the patients being dichotomized according to their pre- or postmenopausal status, and satisfactory diagnostic values may be obtained using a single cutoff point for the entire population.

RESUMO

New poly(ester-amide) copolymers modified with polyethers were developed for carboplatin encapsulation. These new copolymers contain hydrophobic blocks made of tyrosine derivative and dimer fatty acid, and poly(ethylene glycol) (PEG) as hydrophilic blocks. Short-term hydrolytic degradation revealed high water absorption, slight increase of pH of simulated body fluid and change of sample shape, which indicated the erosive mechanism of polymers degradation. Poly(ester-amide)-PEG copolymers were used for microspheres preparation and carboplatin encapsulation. A double emulsification process was used to produce microspheres with an average diameter of 20-30 µm. It was found that the amount of drug released was controlled by the molecular mass of PEG used for microspheres preparation. Mathematical models were used to elucidate the release mechanism of the carboplatin from the microspheres. The results demonstrate that poly(ester-amide)-PEG copolymers may be used for targeted carboplatin encapsulation and release.

RESUMO

The cystic mature teratomas, including dermoid cysts, are one of the most frequently occurring benign ovarian tumors diagnosed in female patients. The process of neoplastic transformation in mature dermoid cysts is applicable only to 1-2% of cases. In our article, we present a rare case of thyroid carcinoma development in adult teratoma in 21-year-old patient. The young age, certain pathomorphological features and clinical data (small size of neoplastic lesion, correct values of tumour markers, unilateral character, regular levels of thyreoglobulin and absence of any significant deviations in imaging examinations), were the basis for attempting to apply the conservative treatment both in the scope of gynecological surgery and in the supplemental endocrinological therapy. In the patient, the one-sided adnexectomy was performed, considering pathological lesions on the adnexa, as well as the other ovary dermoid cyst was enucleated, without the hysteroctomy procedure. Considering the lack of any morphological lesions and functional changes relating to thyroid gland, the treatment was not radicalised in this scope, either. At present, one year after the primary operation treatment, the patient does not manifest any disease symptoms, whereas the other ovary, in the follow-up ultrasound examinations, shows normal size and echostructure. The thyroid-stimulating hormone (TSH) suppression keeps being applied.

RESUMO

The combination of vitamin A and D derivatives with classical chemotherapeutic treatments results in more satisfactory outcomes. The use of drug combinations, such as 9cUAB130 with carboplatin and cisplatin with TAC-101, shows enhanced cytotoxic effects and reductions in ovarian tumor volume compared to single-drug treatments. Combining cisplatin with calcitriol and progesterone increases VDR expression, potentially enhancing the effectiveness of anticancer therapy in ovarian cancer. The effectiveness of vitamin derivatives in anticancer treatment may vary depending on the characteristics of the tumor and the cell line from which it originated. An increase in thiamine intake of one unit is associated with an 18% decrease in HPV infection. Higher intake of vitamin C by 50 mg/day is linked to a lower risk of cervical neoplasia. Beta-carotene, vitamin C, and vitamin E are associated with risk reductions of 12%, 15%, and 9% in endometrial cancer, respectively. A balanced daily intake of vitamins is important, as both deficiency and excess can influence cancer development. It has been observed that there is a U-shaped relationship between group B vitamins and metabolic markers and clinical outcomes.

RESUMO

BACKGROUND: Stress urinary incontinence (SUI) causes both physical and psychological problems to women and their partners. Recently, vaginal radiofrequency (RF) application, as well as the administration of non-crosslinked hyaluronic acid (NCLHA) together with calcium hydroxyapatite (CaHA), has attracted attention for SUI treatment. The current, comparative study evaluated the efficacy and safety of these technologies acting separately and in a combined treatment. METHODS: Sixty women with mild to moderate SUI, aged between 46 and 76 years (mean age 63.2) were divided into three groups intended for different treatments: group I, RF vaginal treatment only, group II, NCLHA plus CaHA periurethral injection only, group III, combined treatment including a single periurethral injection of NCLHA plus CaHA followed by four vaginal applications of RF at intervals of 3-5 days. The clinical effects of the treatments were evaluated by ICIQ-LUTSqol (Polish version) and UDI-6. RESULTS: The obtained results suggest that the symptoms of SUI and the quality of life of the patients improved significantly in each group after the therapies compared to the pre-treatment levels and were more persistent in the third HA + RF group compared to the HA or the RF group.

RESUMO

In the context of the global COVID-19 pandemic, understanding the intricate mechanisms of the body's response to infection and inflammation has become a priority for the medical and research communities. It has been proven that during COVID-19 infection, molecules are secreted-namely organokines, which may directly or indirectly play a role in the pathophysiology of COVID-19. The objective of this study was to scrutinize the potential correlation between the levels of selected myokines (myostatin, agrin, irisin, and myonectin) and the duration of rehabilitation in post-COVID-19 patients. Additionally, the study aimed to investigate whether there is a correlation between the levels of these myokines and the length of hospitalization during COVID-19 treatment. The study was conducted at the Rehabilitation Hospital in Szczecin (Poland). Patients in the study participated in a comprehensive rehabilitation program following COVID-19 treatment. In order to assess the effectiveness of rehabilitation, the following tests were performed: a 6 min walk test with an assessment of exercise tolerance (Borg scale), an assessment of dyspnea severity (mMRC scale), a spirometric assessment of respiratory function, a measurement of arm strength, and an assessment of fatigue using the Fatigue Assessment Scale (FAS). Myokine levels were measured using commercially available enzyme-linked immunosorbent assays (ELISA) according to the manufacturer's instructions. Statistical analysis was performed using Statistica 13.1 software. Lower concentrations of irisin and myonectin and higher concentrations of myostatin correlated with longer rehabilitation time. Baseline levels of specific myokines in post-COVID-19 patients could play a crucial role in anticipating the duration of rehabilitation. The duration of hospitalization for the infection may influence myokine levels in patients recovering from COVID-19.

RESUMO

The absence of non-invasive methods for assessing bone material and structural changes is a significant diagnostic challenge. Dual-energy X-ray absorptiometry (DXA) bone mineral density (BMD) testing is the gold standard for osteoporosis diagnosis. BMD and the trabecular bone score (TBS) have facilitated targeted osteoporosis prevention and treatment in clinical settings. The findings from this study indicate that BMD modulation in young women is influenced by various hormones, potentially compromising the diagnostic precision of BMD for subclinical bone demineralization. A total of 205 women aged 19 to 37 underwent anthropometric measurements and hormonal tests. BMD was determined using DXA, and TBS values were computed from the lumbar spine L1-L4 segment. The multivariate analysis findings suggest that BMD might not be determined by hormones. The relationship between TBS and TSH was statistically significant in the univariate analysis, which indicates the efficacy of further studies to determine the link between TBS and specific hormones. Analyzing the strength of the correlation between TBS and hormones in the univariate analysis shows which factors are worth considering in further analyses. This makes it possible to create better techniques that will help identify young women who are at a higher risk of developing osteoporosis.

RESUMO

Urinary tract infections (UTIs) are among the most common bacterial infections affecting millions worldwide. The increasing emergence of antibiotic-resistant bacteria has become a serious concern in managing UTIs. Therefore, there is a growing interest in using bacteriophages as an alternative or adjunct therapy for UTIs. Bacteriophages are viruses that infect and kill bacteria, making them a promising tool for treating UTIs caused by antibiotic-resistant bacteria. This article provides a quick outlook on using bacteriophages to treat UTIs. We summarize the current understanding of the biology of bacteriophages, the challenges associated with developing phage-based therapies, and the promising results of several case reports and clinical trials. We also highlight the potential of phage therapy as a valuable tool in the fight against antibiotic-resistant UTIs. This quick outlook on a bacteriophage-based approach for treating UTIs offers a timely and informative summary of the current research in this field.

RESUMO

AIM: Evaluation of patient age and time of the prophylactic surgery as well as incidence of genital cancers and precancerous states observed in histopathology of the postoperative material from BRCA1 gene mutation carriers previously treated for breast cancer. MATERIAL AND METHODS: 206 carriers of one of the three most common BRCA1 gene mutations (5382insC, C61G and 4153delA) in the Polish population, who were offered the option of prophylactic salpingo-oophorectomy The study group comprised 85 patients with the diagnosis of breast cancer before gynecological preventive surgery The study group was further divided into two subgroups for more detailed assessment of the tested variables. The first subgroup included 67 patients with breast cancer (unilateral or bilateral synchronous). The second subgroup included 18 patients with bilateral metachronous (the second diagnosis of breast cancer was at least 12 months after the first breast cancer diagnosis). The control group consisted of 121 patients with no cancerous lesions before preventive gynecologic surgery The patients undergoing prophylactic treatment had no prior symptoms in female sexual organ and no changes in the diagnostic tests. RESULTS: The patients with a history of breast cancer underwent genetic testing and preventive surgery of the genital tract at a significantly later age than controls (respectively p = 0.0003, p = 0.0006). The patients with bilateral metachronous breast cancer underwent preventive surgery significantly earlier (p = 0.03). There was a trend indicating a 2.5 times higher risk of developing ovarian cancer among BRCA1 mutation carriers who had already been diagnosed and treated for breast cancer when compared to women without breast cancer diagnosis. The incidence of other genital cancers and precancerous states in BRCA1 gene mutation carriers with history of breast cancer was not statistically significant as compared to controls. Data on the clinical stage, morphological grade, histological type, age and type of pathology and the type of BRCA1 gene mutation did not show a statistically significant difference between the groups. CONCLUSIONS: Each patient diagnosed with breast cancer should be strongly recommended a genetic test to reduce adverse consequences resulting from postponing the test and, if applicable, the preventive operation until later in life. Preventive surgery should be considered especially in BRCA1 gene mutation carriers previously treated for breast cancer because of the increased risk of ovarian cancer

RESUMO

The aim of this study was to analyze the locus of health control, self-efficacy and stress coping styles of female patients treated for ovarian cancer. Learning the styles of coping with stress in patients with ovarian cancer may contribute to improve their quality of life after cancer diagnosis. A series of Pearson's r-analyses was performed in the order to evaluate the hypotheses regarding the relationship between styles of coping with stress, the locus of health control and self-efficacy. A total of 151 female patients participated in this study. Standardized psychological questionnaires were used: the General Self-Efficacy Scale (GSES) to measure coping with difficult situations and obstacles, the Multi-Dimensional Health Locus of Control Scale (MHLC) to measure health control and the Convergence Insufficiency Symptom Survey (CISS) to measure stress coping styles. All questionnaires had an adaptation in Polish. Patients using task-focused and socializing styles had higher self-efficacy, whereas focusing on negative emotions resulted in lower self-efficacy. External locus of health control was related to a task-focused approach to treatment. On the other hand, the focus on negative emotions was related to the feeling that the fate of patients was decided by chance. Self-efficacy was positively associated with internal locus of health control and with external control, which means the influence of others. The results of our study indicate the need for a multidimensional approach to the treatment of female patients with ovarian cancer. The psychological condition of female patients has an ongoing relationship with their physical health.

RESUMO

The COVID-19 pandemic affects women's mental health, because they are more predisposed to vulnerabilities and adverse impacts. Therefore, is important to find strategies for preventing and treating these mental health consequences in the female population. The main purposes of our study were to determine the level of social support received by peri- and postmenopausal women during the SARS-CoV-2 pandemic, as well as factors related to this level with reference to health status and sociodemographic variables. A total of 218 women in peri- and postmenopausal status participated in the study. The study assessed depression (Beck Depression Inventory), anxiety (the Spielberg State-Trait Anxiety Scale), climacteric symptoms (the Blatt-Kupperman Index), social support (the Inventory of Social Supportive Behaviors). The majority of the respondents had a moderate level of anxiety as a state (40.8%), a low level of anxiety as a trait (51.4%), no depressive symptoms (75.2%) and no climacteric symptoms (52.3%). Age was found to significantly correlate with anxiety as a state (p = 0.036). The anxiety as state was significantly stronger in people with higher education than in people with secondary education (p = 0.019). Professionally inactive women had more emotional (p = 0.05) and appraisal (p = 0.014) support than women who work. The analysis demonstrated no statistically significant correlation between social support and depression, anxiety or climacteric symptoms (p > 0.05). The majority of peri- and postmenopausal women had no depressive symptoms and/or anxiety symptoms. Professionally inactive women had more emotional and appraisal support than women who work. The analysis demonstrated no statistically significant correlation between social support and depression, anxiety or climacteric symptoms.
