High Prevalence of Borrelia burgdorferi Antibodies in Jaworzno, Poland: A Retrospective Study Revealing Endemic Lyme Borreliosis.

BACKGROUND This retrospective study of 704 adult residents of Jaworzno, Poland, aimed to evaluate medical personnel awareness of episodes of Lyme borreliosis and serum antibody levels for Borrelia burgdorferi sensu lato. MATERIAL AND METHODS This study included 704 residents of Jaworzno, Poland, who had no more than 12 months between tick bite and screening. The study consisted of a self-designed questionnaire survey and an analysis of IgG and IgM antibodies against B. burgdorferi sensu lato using an enzyme-linked assay (ELISA) and Western blot analysis, when necessary, to confirm the results. RESULTS A total of 558 residents (79.3%) confirmed having contact with a tick, 84 (11.9%) responded that they did not remember having contact with a tick, and 62 (8.8%) denied having contact with a tick. Regarding IgG, the ELISA showed 183 (25.99%) positive, 440 (62.5%) negative, and 81 (11.5%) equivocal results. Regarding IgM, the ELISA showed 180 (25.57%) positive, 435 (61.79%) negative, and 89 (12.64%) equivocal results. Positive and equivocal results for the IgG and IgM classes using the ELISA test were confirmed in 36 cases (13.64%) for IgG and in 53 cases (19.70%) for IgM using Western blot analysis. CONCLUSIONS The ELISA method obtained similar values for positive, negative, and equivocal results in the serological test. This was reflected in the survey conducted on residents who reported a tick bite and later received a positive result in the ELISA test as well as an approximate time between the bite and removal of the tick.

Dynamics of Microbiome Changes in the Endometrium and Uterine Cervix during Embryo Implantation: A Comparative Analysis.

BACKGROUND The microbiome is the collection of all micro-organisms and their genes, which naturally live in and on the body. The cervical and endometrial bacterial microbiome has previously been reported to affect fertility and influence the outcomes of assisted reproductive therapy (ART), including embryo transfer. This study aimed to evaluate the cervical and endometrial bacterial microbiome in 177 women treated for infertility before, during, and after embryo implantation, and the outcomes. MATERIAL AND METHODS Cervical and endometrial swabs were collected from 177 women diagnosed with infertility at 3 time points: (1) during the initial examination, (2) during implantation, (3) 10-14 days after implantation. Next-generation sequencing (NGS) was used to analyze the bacterial microbiome. Taxonomic identification was performed with the Usearch algorithm. RESULTS There was a significant change in the number of patients with Escherichia coli depending on the collection time. For the first swab collection, there were significant negative relationships between the percentage of Gardnerella vaginalis and Lactobacillus spp. For the second collection, there was a negative relationship between Lactobacillus helveticus and Lactobacillus jensenii. For the third collection, negative relationships were found between Escherichia coli and Lactobacillus spp. A similar distribution of the bacterial microbiome was observed in all 3 swab collections. CONCLUSIONS Lactobacillus spp. were the main bacteria identified in the cervix and endometrium, present before, during, and after successful embryo transfer. E. coli and G. vaginalis reduced the protective effect of Lactobacilli before, during, and after embryo transfer.

The influence of selected microRNAs on the expression profile of genes and proteins related to the tumor necrosis factor-alpha signaling pathways in endometrioid endometrial cancer.

PURPOSE: Tumor necrosis factor exerts many adverse biological effects, from cell proliferation to cell death. Accurate diagnosis and treatment are therefore difficult due to many factors influencing tumor necrosis factor-alpha (TNF-α) signaling, including microRNAs (miRNAs), especially in tumors. The aim of the study was to determine the influence of miRNAs on the expression profile of genes and proteins related to TNF-α signaling in endometrial cancer. METHODS: The material consisted of 45 endometrioid endometrial cancer and 45 normal endometrium tissue samples. Gene expression was determined with microarrays and then validated for TNF-α, tumor necrosis factor receptor 1 (TNFR1) and 2 (TNFR2), caveolin 1 (CAV1), nuclear factor kappa B subunit 1 (NFKB1), and TGF-beta activated kinase 1 (MAP3K7)-binding protein 2 (TAB2) using real-time quantitative reverse transcription reaction (RT-qPCR). The protein concentration was assessed by enzyme-linked immunosorbent assay (ELISA). In addition, differentiating miRNAs were identified using miRNA microarrays and their relationships with TNF-α signaling genes were evaluated using the mirDIP tool. RESULTS: TNF-α, TNFR1, TNFR2, CAV1, NFKB1, and TAB2 were upregulated both on the mRNA and protein levels. The decrease in the activity of miR-1207-5p, miR-1910-3p, and miR-940 may be related to CAV1 overexpression. Similarly for miR-572 and NFKB1 as well as miR-939-5p and TNF-α. In turn, miR-3178 may partially inhibit TNFR1 activity up to grade 2 cancer. CONCLUSION: TNF-α signaling, especially the TNF-α/NF-κB axis, is disrupted in endometrial cancer and worsens with disease progression. The observed changes may be the result of miRNAs' activity in the initial stage of endometrial cancer and its gradual loss in later grades.

Detection and Genotyping of Human Papillomavirus (HPV16/18), Epstein-Barr Virus (EBV), and Human Cytomegalovirus (HCMV) in Endometrial Endometroid and Ovarian Cancers.

The purpose of this study was to evaluate the relationship between human papillomavirus (HPV16/18), Epstein-Barr virus (EBV), and human cytomegalovirus (HCMV) infections and the occurrence of ovarian cancer in 48 women, of whom 36 underwent surgery and chemotherapy (group A), 12 in whom surgery was sufficient (group B), and 60 with endometroid endometrial cancer stage G1-G3 (group C), compared to patients in whom the uterus and its appendages were removed for nononcological reasons (control group). The detection of HPV, EBV, and HCMV in tumor tissue and normal tissue was performed using the real-time polymerase chain reaction (RT-PCR) technique. A statistically significantly higher risk of endometrial cancer was noted in patients infected only with HCMV (OR > 1; p < 0.05). In contrast, a significantly higher risk of ovarian cancer in group A was associated with HPV16, HPV18, and EBV (OR > 1; p < 0.05); a significantly higher risk of ovarian cancer in group B was associated with HPV18 and HMCV (OR > 1; p < 0.05). The obtained results suggest that HCMV infection is associated with the development of a stage of ovarian cancer when treatment can be completed with surgery alone. Meanwhile, EBV appears to be responsible for the development of ovarian cancer in more advanced stages.

Reinfections from SARS-CoV-2: A Retrospective Study from the Gyncentrum Genetic Laboratory in Sosnowiec, Poland, April 2020 to July 2022.

BACKGROUND The increasing number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfections has opened a new research direction related to analyzing long-term immune response and accurately characterizing individual cases of reinfection to understand its mechanism and estimate the risk of widespread reinfection both locally and globally. This retrospective study from the Gyncentrum Genetic Laboratory in Sosnowiec, Poland aimed to evaluate reinfections from SARS-CoV-2 between April 2020 and July 2022. MATERIAL AND METHODS The study extended the previously published report on SARS-CoV-2 infection cases in Poland by analyzing 8041 reinfections diagnosed with real-time reverse transcription-polymerase chain reaction (RT-PCR) assay. Data were collected on the amount of time elapsed from the first infection to the next and, based on these data, all results were divided into several groups for statistical analysis: 0-44, 45-90, 91-200, 201-310, 311-420, and >420 (days). RESULTS The study showed that of the 8041 patients who experienced reinfection, the vast majority (5505) became reinfected more than 310 days after the original infection, even though the average time between infections was 354.3 days. Statistical analysis revealed that the risk of SARS-CoV-2 reinfection increases with time and that this relationship becomes statistically significant after the 200th day following the initial infection (p<0.01). CONCLUSIONS We have shown that acquired immunity to SARS-CoV-2 infection is relatively short-lived - it starts diminishing about 6 months after the initial positive test. Moreover, the risk of reinfection is very high more than 1 year after the initial infection.

A Retrospective Population Study of 385 191 Positive Real-Time Reverse Transcription-Polymerase Chain Reaction Tests For SARS-CoV-2 from a Single Laboratory in Katowice, Poland from April 2020 to July 2022.

BACKGROUND This retrospective population study identified 385 191 positive real-time reverse transcription-polymerase chain reaction (RT-PCR) tests for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from a single laboratory in Katowice, Poland, from April 2020 to July 2022. MATERIAL AND METHODS The material was nasopharyngeal, nasopharyngeal swab or bronchial lavage, and bronchoalveolar lavage (BAL) to confirm or exclude SARS-CoV-2 infection with the RT-PCR technique. Personal data are use according to the Provisions on the Protection of Personal Data by the Gyn-Centrum laboratory. RESULTS In 9 months of 2020, the number of SARS-CoV-2 results was 88 986; in 2021, it was 168 439, and in the first 7 months of 2022, it was 12 786. In 2020, the highest number of positive results was recorded in the third quarter (83 094 cases); 2021, in the 1st, 2nd, and 4th quarters (58 712; 37 720; and 71 753 cases, respectively), and in 2022, in the 1st quarter (127 613 cases) of the year. A positive result was observed more often in women and people aged 30-39, followed by those 40-49 years. Patients aged 10-19 years comprised the smallest population of SARS-CoV-2-positive cases. CONCLUSIONS In the Polish population studied, from April 2020 to July 2022, the detection rates of SARS-CoV-2 positivity were significantly higher for women than for men and in the 30-49 age group for both sexes. Also, the infection detection rate of 385 191 out of 1 332 659 patient samples, or 28.9%, supports that the Polish society adhered to public health recommendations for infection control during the COVID-19 pandemic.

Endothelin-3 is epigenetically silenced in endometrioid endometrial cancer.

PURPOSE: Changes in the activity of endothelins and their receptors may promote neoplastic processes. They can be caused by epigenetic modifications and modulators, but little is known about endothelin-3 (EDN3), particularly in endometrial cancer. The aim of the study was to determine the expression profile of endothelin family and their interactions with miRNAs, and to assess the degree of EDN3 methylation. METHODS: The study enrolled 45 patients with endometrioid endometrial cancer and 30 patients without neoplastic changes. The expression profile of endothelins and their receptors was determined with mRNA microarrays and RT-qPCR. The miRNA prediction was based on the miRNA microarray experiment and the mirDB tool. The degree of EDN3 methylation was assessed by MSP. RESULTS: EDN1 and EDNRA were overexpressed regardless of endometrial cancer grade, which may be due to the lack of regulatory effect of miR-130a-3p and miR-485-3p, respectively. In addition, EDN3 and EDNRB were significantly downregulated. CONCLUSION: The endothelial axis is disturbed in endometrioid endometrial cancer. The observed silencing of EDN3 activity may be mainly due to DNA methylation.

miRNAs Participate in the Regulation of Oxidative Stress-Related Gene Expression in Endometrioid Endometrial Cancer.

Reactive oxygen species are formed as by-products of normal cell metabolism. They are needed to maintain cell homeostasis and signaling, which is possible due to defense systems. Disruption of this balance leads to oxidative stress that can induce cancer. Redox regulation by miRNAs may be a potential therapeutic target. The aim of the study was to assess the activity of genes associated with oxidative stress in endometrial cancer and to determine their relationship with miRNAs. The study included 45 patients with endometrioid endometrial cancer and 45 without neoplastic changes. The expression profile of genes associated with oxidative stress was determined with mRNA microarrays, RT-qPCR and ELISA. The miRNA prediction was performed based on the miRNA microarray experiment and the mirDB tool. PRDX2 and AQP1 showed overexpression that was probably not related to miRNA activity. A high level of PKD2 may be the result of a decrease in the activity of miR-195-3p, miR-20a, miR-134. A SOD3 level reduction can be caused by miR-328, miR-363. In addition, miR-363 can also regulate KLF2 expression. In the course of endometrial cancer, the phenomenon of oxidative stress is observed, the regulation of which may be influenced by miRNAs.

Trichopsychodermatology: trichotillomania and trichophagia leading to Rapunzel syndrome.

Introduction: The Rapunzel syndrome occurs when the trichobezoar (hair ball) extends beyond the small intestine and sometimes even into the colon, producing long, tail-like hair extensions. Aim: To present cases of trichobezoars, an extremely rare human intestinal disease caused by the ingestion of hair (trichophagia). Material and methods: In this retrospective study, we assessed the medical records of 2 patients diagnosed with Rapunzel syndrome admitted to Academic Clinical Hospital No. 2 in Rzeszow, Poland. Results: The first patient was a 15-year-old girl. The abdominal ultrasound examination revealed an abnormal, non-compressible structure with the approximate dimensions of 12 × 11 cm in the epigastrium, with a strong shadow obscuring the view. Gastroscopy was performed and a tumour sample was taken for histopathological examination, which confirmed the diagnosis of a trichobezoar. The patient's mother did not agree to her daughter's psychiatric treatment. The second patient was a 15-year-old girl who reported to the Emergency Room in critical condition due to dehydration and long-term emesis with symptoms of cachexia. Ileotomy with the removal of two trichobezoars with a diameter of about 5 cm and 7 cm was performed. The patient was discharged for treatment at the Mental Health Clinic for trichotillomania. Conclusions: Trichobezoars give non-specific symptoms that may imitate other diseases for example tumours. Psychotherapy is the recommended treatment and follow-up visits are important in preventing relapses.

Epigenetic regulation of autophagy in gastrointestinal cancers.

The development of novel therapeutic approaches is necessary to manage gastrointestinal cancers (GICs). Considering the effective molecular mechanisms involved in tumor growth, the therapeutic response is pivotal in this process. Autophagy is a highly conserved catabolic process that acts as a double-edged sword in tumorigenesis and tumor inhibition in a context-dependent manner. Depending on the stage of malignancy and cellular origin of the tumor, autophagy might result in cancer cell survival or death during the GICs' progression. Moreover, autophagy can prevent the progression of GIC in the early stages but leads to chemoresistance in advanced stages. Therefore, targeting specific arms of autophagy could be a promising strategy in the prevention of chemoresistance and treatment of GIC. It has been revealed that autophagy is a cytoplasmic event that is subject to transcriptional and epigenetic regulation inside the nucleus. The effect of epigenetic regulation (including DNA methylation, histone modification, and expression of non-coding RNAs (ncRNAs) in cellular fate is still not completely understood. Recent findings have indicated that epigenetic alterations can modify several genes and modulators, eventually leading to inhibition or promotion of autophagy in different cancer stages, and mediating chemoresistance or chemosensitivity. The current review focuses on the links between autophagy and epigenetics in GICs and discusses: 1) How autophagy and epigenetics are linked in GICs, by considering different epigenetic mechanisms; 2) how epigenetics may be involved in the alteration of cancer-related phenotypes, including cell proliferation, invasion, and migration; and 3) how epidrugs modulate autophagy in GICs to overcome chemoresistance.

Cutaneous metastasis as the first sign of renal cell carcinoma - crossroad between literature analysis and own observations.

Introduction: Metastatic disease can be observed in nearly 25% of all renal cell carcinoma cases (RCC). This can present in the skin as a late symptom of the disease or as a manifestation of an undetected, asymptomatic RCC. Aim: To review the literature and present a case study of cutaneous metastasis in primary genitourinary malignancy, especially RCC in order to broaden the related knowledge. Material and methods: The first stage of our work was focused on presenting the results of the literature review about cutaneous metastasis in the patients with renal cell carcinoma. Next, taking into account that this type of metastasis associated with RCC is relatively rare, we have decided to present a patient aged 68 with incidentally detected skin metastases of RCC located on the scalp. Results: It was diagnosed as a primary manifestation of advanced disease. Computed tomography scans showed a solid mass in the left kidney. Following surgical excision of the skin lesion, a left-side nephrectomy was performed. Conclusions: Cutaneous metastases of RCC present an unfavourable prognosis, however, remission is possible subsequent to early diagnosis and appropriate surgical excision.

Distribution and Morphological Characteristics of Oligodendrocytes in Selected Areas of the Brain of Male and Female Red Kangaroos (Macropus rufus).

This study was carried out on six adult red kangaroos of both sexes. To determine the location of the oligodendrocytes (OLGs) of the hippocampus (Hip) and corpus callosum (CC), the method of impregnation of the neuroglia with silver salts was applied. The iron distribution in the OLGs was determined by the histochemical method. The Nissl method was used to determine the location of the brain structure and to analyze the number of OLGs. In the Hip, these cells are located one beside another, mainly in blood vessels and neurons; in the neocortex (NC), they are located in layers I-VI; and in the CC, they are arranged in characteristic rows and accompany both nerve fibers and blood vessels. The analysis of the results obtained by the chosen methods in the Hip, NC, and CC in males and females did not show statistically significant differences in the distribution and location of the red kangaroo OLGs. The involvement of these cells is a physiological process that proceeds in a similar manner throughout the life of individuals and actively influences the metabolism of neurons and myelin.

Clinical and molecular evaluation of patients with ovarian cancer in the context of drug resistance to chemotherapy.

The present study aimed to evaluate changes in the expression patterns at the gene and protein levels associated with drug resistance. The study group included 48 women who had a histopathologically confirmed diagnosis of stage I-IV ovarian cancer, they were divided into two subgroups (groups A and B). In group A, there were 36 patients in whom surgical treatment was supplemented with first-line chemotherapy according to current standards. Within this patient group, 5 had stage I (14%), 5 had stage II (14%), 25 had stage III (69%), and 1 had stage IV ovarian cancer (3%). Drug resistance was found after the third cycle of chemotherapy in 17 patients (71%) and after the sixth cycle in 7 patients (29%). Group B included 12 women with type I ovarian cancer, including 11 with stage I and 1 patient with stage IV ovarian cancer. The oncological treatment required only surgery. The control group (C) included 50 women in whom the uterus and adnexa were surgically removed for non-oncological reasons. Significantly higher levels of carcinoma antigen 125 CA-125 and human epididymis protein 4 HE4 were observed in group A and in menopausal women. Moreover, drug resistance was associated with significantly higher levels of CA-125 (p < 0.05). The genes UBA2, GLO1, STATH, and TUFT1 were differentiated in test samples from control samples. Moreover, drug resistance was associated with significantly higher expression of GLO1. The results of these assessments indicated the strong link between UBA2 and hsa-miR-133a-3p and hsa-miR-133b; GLO1 and hsa-miR-561-5p; STATH and hsa-miR-137-3p and hsa-miR-580-3p; and TUFT1 and hsa-miR-1233-3p and hsa-miR-2052. Correlation analysis showed a significant correlation between CA-125 and HE4 levels. Moreover, a significant correlation between TUFT1 mRNA and UBA2, GLO1, STATH (negative correlation), and TUFT1 in relation to CA-125 and HE4 (p < 0.05) was noted in all patients. In view of the lack of screening tests for ovarian cancer, the occurrence of the described correlation may be inscribed as an attempt to establish an assay that meets the criteria of a screening test and thus increase the early diagnosis of ovarian cancer.

Oligodendrocytes in the periaqueductal gray matter and the corpus callosum in adult male and female domestic sheep.

There is little information about oligodendrocytes (OLGs) in the Periaqueductal Gray matter (PAG). The literature has not provided data on the number, morphology, or quantification of the expression of the OLG protein yet. Myelin Basic Protein (MBP) in this region of the Central Nervous system (CNS). The study aimed was to perform a comparative analysis: the location and morphology of OLGs, the cellular and regional distribution of iron, and the number of OLGs in PAG and corpus callosum (CC) of adult 16 male and 16 female sheep. To determine the location of the OLG of PAG and CC, the method of impregnation of the neuroglia with silver salts was applied. In turn, the Nissl method was used to determine the location of the brain structure and to analyse the number of OLG. The performed analysis showed that PAG, OLGs are located singly or in pairs in blood vessels and neurons, while in CC they are arranged in characteristic rows and accompany both nerve fibres and blood vessels. Immunofluorescent staining for the presence of MBP confirmed the location of OLGs in male and female sheep. Morphometric analysis showed the importance of these glial cells in OLG-myelin fibres, correlation in adults regardless of sex even after the creation of the completion of myelin. The results obtained indicate that the functions of OLGs are not only confined to myelination in young individuals, but also play a crucial role in the brain of adults. Our observations seem to be useful to better understanding OLGs biology.

Marking the Profile of the Microflora of the Endometrium and Uterine Cervix in Women as a Potential Factor Determining the Effectiveness of In Vitro Fertilization.

One promising research trend involves evaluating the influence of microbiota in the reproductive system of women on becoming pregnant and maintaining pregnancy. The goal of this study was to define the microflora profile of the endometrium and uterine cervix in women qualified for an in vitro fertilization (IVF) procedure, which is expected to contribute to increasing the percentage of successful IVF implantations. Based on the conducted molecular analysis in the collected swabs, 22 bacterial strains were identified. Eleven strains (57%) that were isolated belong to the physiological microflora, the most common strain of which was Lactobacillus. Eight of the isolated strains (33%) were pathological microflora, among which the most common bacteria were from the Enterobacteriaceae family (which includes E. coli, Shigella, and Salmonella). Finally, three of the bacterial strains (10%) may be a component of both physiological or pathological microflora of the vagina: Bifidobacterium breve, Bifidobacterium longum group, and Alloscardovia omnicolens. The presence of Escherichia coli was detected in six women, Staphylococcus aureus also in six patients, Atopobium parvulum in three, Streptococcus salivarius group in three, Enterococcus faecalis in four, and Aerococcus christensenii in two patients. We found statistically significant relationships (p < 0.05) between Lactobacillus fermentum and Enterococcus faecalis, Lactobacillus delbrueckii and Escherichia coli groups, Lactobacillus FN667084_s and Staphylococcus aureus groups, as well as Lactobacillus fermentum and Streptococcus agalactiae. Based on the conducted study, it may be confirmed that the endometrium is, to a large extent, colonized by lactic acid bacilli. Apart from that, endometrial dysbiosis was not noted in patients qualified for the IVF procedure.

Expression Profile of mRNAs and miRNAs Related to the Oxidative-Stress Phenomenon in the Ishikawa Cell Line Treated Either Cisplatin or Salinomycin.

The oxidative stress phenomenon is a result of anticancer therapy. The aim of this study was the assessment of gene expression profile changes, and to determine the miRNAs regulating genes' transcriptional activity in an Ishikawa endometrial cancer culture exposed to cisplatin or salinomycin, compared to a control culture. The molecular analysis comprised the microarray technique (mRNAs and micro RNA (miRNA), the real-time quantitative reverse transcription reaction (RTqPCR), enzyme-linked immunosorbent assay (ELISA) reactions, and Western blot. NR4A2, MAP3K8, ICAM1, IL21, CXCL8, CCL7, and SLC7A11 were statistically significantly differentiated depending not only on time, but also on the drug used in the experiment. The conducted assessment indicated that the strongest links were between NR4A2 and hsa-miR-30a-5p and has-miR-302e, MAP3K8 and hsa-miR-144-3p, CXCL8 and hsa-miR-140-3p, and SLC7A11 and hsa-miR-144-3p. The obtained results suggest that four mRNAs-NR4A2, MAP3K8, CXCL8 and SLC7A11-and four miRNAs-hsa-miR-30a-5p, hsa-miR-302e, hsa-miR-144-3p and hsa-miR-140-3-changed their expressions regardless of the chemotherapeutic agent used, which suggests the possibility of their use in monitoring the severity of oxidative stress in endometrial cancer. However, considering the results at both the mRNA and the protein level, it is most likely that the expressions of NR4A2, MAP3K8, CXCL8 and SLC7A11 are regulated by miRNA molecules as well as other epigenetic mechanisms.

Evaluation of the Risk of Birth Defects Related to the Use of Assisted Reproductive Technology: An Updated Systematic Review.

Fertility problems constitute a serious medical, social, and demographic problem. With this review, we aim to critically appraise and evaluate the existing literature surrounding the risk of birth defects in offspring conceived using techniques based on assisted reproductive technology (ART). Based on searches of the literature in PubMed and ScienceDirect, we obtained a total of 2,003,275 works related to the topic. Ultimately, 11 original papers published in the last 10 years qualified for inclusion in the study. Based on five studies included in this analysis, it was shown that ART significantly increases the risk of congenital malformations in associated newborns. Due to the specifics of given studies, as well as potential confounding risk factors, this influence cannot be ignored. Therefore, considering the information contained in the articles included in this systematic review, it was determined that the risk of birth defects is not directly related to the use of ART itself but also depends on the age of partners, causes of infertility, comorbidities, and the number of fetuses during a pregnancy, as well as many other factors not covered in the literature. It is thus necessary to impress upon infertile couples who wish to have offspring that the use of ART is not risk-free but that the benefits outweigh the risks. Further education in this field, as well as social understanding, is also required.

The Impact of Surgical Treatment with Adjuvant Chemotherapy for Ovarian Cancer on Disorders in the Urinary System and Quality of Life in Women.

Ovarian cancer is the fourth-most-common cause of death among all malignant cancers in women in Poland. This study aimed to compare the functioning of the urinary system and quality of life in women in the 12-month period following the completion of surgery or adjuvant treatment for ovarian cancer, with patients who underwent a hysterectomy for non-oncological reasons (control group). The study group consisted of 50 patients diagnosed with stage I−III ovarian cancer. Among 38 patients with type II ovarian cancer (group A), surgery followed by first-line chemotherapy was performed. Within this group of patients, 20 had stage I ovarian cancer, while 18 had stage II ovarian cancer. The study was performed at least 6 months after the final chemotherapy cycle, with no clinical, marker or radiological recurrence determined. On the other hand, in 12 patients with stage I type I ovarian cancer, oncological treatment consisted of only surgery, without the need for adjuvant chemotherapy, due to the low stage of the lesions (group B). In turn, the control group consisted of 50 women who underwent uterine removal for non-oncological reasons (group C). The assessment of quality of life was conducted using the questionnaires: Satisfaction with Life Scale (SWLS); Incontinence Impact Questionnaire, short form (IIQ-7); Urogenital Distress Inventory (UDI-6); and the Sexual Satisfaction Scale for 3, 6, 9, and 12 months after the conclusion of oncological treatment. During the follow-up, a significant reduction in the quality of everyday life and sexual life was noted among patients with ovarian cancer, more pronounced in group B, compared to the control group (p < 0.05). The risk of urinary incontinence is independent of the treatment regimen chosen for ovarian cancer. It is necessary to consider comprehensive psychological care and sexual therapy in patients with ovarian cancer and their families.

Changes in the Sexual Behavior of Partners in Each Trimester of Pregnancy in Otwock in Polish Couples.

The aim of this study was to improve knowledge regarding pregnant couples by assessing changes in their sexual behavior, the reasons for the frequency and forms of intercourse, and the self-sexuality of partners in each trimester of pregnancy. As a result, 100 couples were qualified to take part in the final study, with 100 men and 100 women examined at intervals equivalent to the trimesters of pregnancy. These women (n = 100) and men (n = 100) were partners. Each of the studied couples was assessed in the trimesters of pregnancy. A prospective examination was conducted based on the observation of the same people, which were heterosexual couples, throughout pregnancy. The data used in the study was obtained using Davies' Sexual Satisfaction Scale (DSSS), as well as an original survey on the sexuality of people during pregnancy (SARSS). The survey allowed us to obtain sociodemographic (metrics) information along with information regarding the sexual activity, satisfaction, and sexual attraction of the partners. All questionnaire questions were answered in paper form. There was a statistically significant drop in sexual intercourse from the first trimester in the second and third trimesters. The frequency of masturbation increased in men and decreased in women. The most common cause of sexual abstinence during the pregnancy was cited as fear for the fetus by all genders. A statistical analysis indicated that the average overall scores of the DSSS for the examined women in the first trimester of pregnancy were statistically significantly higher than in the two subsequent trimesters (p < 0.05). Sexual satisfaction, measured through both DSSS and SARSS, was also strongly correlated with the level of satisfaction in the assessment of the partner relationship and with the sense of one's own attractiveness (p < 0.05). Changes in sexual behavior and sexual problems are often exposed or worsened during a first pregnancy and can have negative impacts on a person and the future of relationships. Medical staff should be trained in the assessment of sexual difficulties in people during pregnancy, in order to conduct reliable education and increase the awareness of couples regarding sexual and reproductive health.

Does SARS-CoV-2 Affect Male Urogenital System?

BACKGROUND: Widely known facts about Sars-Cov-2 infection's impact on urogenital system may play a relevant role in under-standing, diagnosing, and preventing male urological disorders. Sars-CoV-2 attacks the vascular endothelium of the entire organism; therefore, infection complications are visible in various organs. Relatively small number of original studies are available on Sars-CoV-2 infection and the effect on the reproductive system and fertility in men. The vast majority of publications focus only on discussing the effects of COVID-19 infection on just one aspect of male urology or fertility. OBJECTIVES: The aim of this review was to present the current understanding of the effects of COVID-19 infection on the male genitourinary system in the context of nephrological and reproductive system complications in men, considering the potential pathomechanisms causing significant nephrological disorders in the course of viral infection, as well as long-term effects of Sars-CoV-2 infection. We tried to make clinicians aware of urogenital complications in the course of COVID-19 occurrence and encourage them to create preventive procedures. METHODS: The article presented has been classified by us as "review". Of course, when searching for publications and making their critique, we focused primarily on the words: "Sars-CoV-2", "male urogenital system", "male infertility", "lower urinary tract symptoms". Therefore, there was no explicit and rigorous work selection methodology. Search strategies were based on the experience of the authors of the work. In order to select articles for the systematic review, literature searches were conducted on PubMed (https://pubmed.ncbi.nlm.nih.gov) using the following keywords: "Sars-CoV- 2" AND "male urogenital system" OR "male infertility" The search results were retrieved and manually screened for duplicate removal. Then abstracts and titles were checked for relevance. The articles were selected if they met the following inclusion criteria: human studies, focus on Sars-CoV-2 and male urogenital system or male infertility, published from 2020 to 2021, written in English, free full-text available. We included clinical trials, meta-analyses, randomized controlled studies, reviews, systematic reviews. RESULTS: After the literature search, a total of 267 articles were retrieved, including 153 reviews, 53 systematic reviews, and 61 original articles. Eventually, after abstract and title screening, 2 original articles, 29 reviews, and 8 systematic reviews were accepted. In our review paper, we presented data from 2 systematic reviews, 17 reviews, 2 meta-analyses, 1 case study, and 18 original articles, including 3 animals studies, 2 in vitro studies, and 14 human studies. CONCLUSION: Serious concerns for urologists among COVID-19 patients should be mainly orchitis, male infertility, priapism, erectile dysfunction, and lower urinary tract symptoms. It seems that the conclusions drawn should be treated with caution because, as mentioned above, in a pandemic, urinary complications are underdiagnosed and there are too few clinical trials and case reports.
