Background and Objectives: Polycystic ovary syndrome (PCOS) is an endocrine disorder characterized by multiple hormonal and metabolic abnormalities, including insulin resistance, hyperandrogenism, and disturbances in lipid and carbohydrate metabolism. The objective of this study is to assess the quality of life of women diagnosed with polycystic ovary syndrome (PCOS) and to identify any factors within the study group that may impact the scores related to quality of life. Materials and Methods: This research was carried out among women diagnosed with PCOS. An original questionnaire, developed through an online Google Forms survey, was utilized as the research instrument and distributed through social networks and support groups to women facing PCOS. This study encompassed a participant pool of 200 women with PCOS, aged 24 years or older. For the analytical component, Pearson’s χ2 test was employed—a nonparametric test designed to assess the relationship between two variables measured on a qualitative scale. The chosen level of statistical significance was set at p < 0.05. Results: The analysis revealed that the quality of life of the women under study was not linked to the duration of the disease or comorbidities. However, a significant association was observed with the inconvenience caused by PCOS symptoms. Women experiencing very bothersome symptoms of PCOS reported a lower quality of life compared to those with symptoms rated as not very bothersome. Despite the majority of women with PCOS rating their quality of life as good or very good, they often find the associated symptoms of PCOS bothersome. Women reporting lower quality of life tend to acknowledge the impact of PCOS on their lives, experience a sense of lack of control over the disease, struggle with depression, and do not accept their physical appearance. Conclusions: Hence, the support from specialists like endocrinologists, gynecologists, and nutritionists becomes crucial for many women dealing with PCOS. Adopting a healthy lifestyle, incorporating a balanced diet, and engaging in regular physical activity can assist in managing the troublesome symptoms of PCOS, thereby enhancing overall quality of life. In instances of emotional difficulties, seeking psychological support is equally important, and the significance of support and acceptance from loved ones should not be overlooked.

Background and Objectives: reproductive disorders are a serious global concern in medical, social, and demographic contexts. According to estimates, approximately 10–15% of couples around the world suffer from infertility. Numerous studies have shown that modifiable lifestyle factors, such as a high-fat diet, a postponed decision to start a family, tobacco smoking, alcohol consumption, risky sexual behavior, psychiatric diseases, and chronic stress, have a negative influence on the fertility of women. The main goal of this study is to assess the knowledge of women about reproductive health, infertility risk factors, and causes of infertility and to determine whether the level of this knowledge varies based on sociodemographic variables. Materials and Methods: a survey was conducted among 111 patients who anonymously filled in a questionnaire comprising questions regarding fertility and its deficiencies. The results were analyzed using the Chi-square test and Fisher’s test. Results: the survey results indicated that women had a good or very good level of knowledge of the causes of infertility. The obtained test results were statistically significant (p < 0.05), but the studied group did not possess sufficient knowledge of the symptoms characterizing the diseases related to limited fertility (p > 0.05). The level of knowledge on the diagnosis of infertility did not depend on the age of the examined people, their educational level, or personal experience in this field (p > 0.05). The results also revealed that the awareness of women on reproductive health was poor. The studied women had a low level of knowledge of infertility risk factors, and their knowledge did not correlate with age, educational level, or personal experiences. Conclusions: information on the aspects of reproductive health should be widely disseminated through public educational campaigns, aimed at correcting erroneous convictions among women about the risk factors for infertility and assisting them in improving fertility.

Hysteroscopy is an endoscopic diagnostic and therapeutic method traditionally performed under general anesthesia but increasingly under local anesthesia. Today, it is considered the gold standard in gynecology. This minimally invasive procedure allows for a detailed assessment of the uterine cavity’s interior and the removal of abnormal changes within it and is applicable to patients of all ages. Background/Objectives: The purpose of the present study was to evaluate pain during hysteroscopy under local anesthesia at different stages of the procedure, identifying which stage is the most painful (GUBBINI Mini Hystero-Resectoscope; Tontarra Medizintechnik, Tuttlingen, Germany). Methods: The study included patients between the ages of 21 and 80 years. They were divided into two groups: the diagnostic hysteroscopy (HD) and the operative hysteroscopy (HO) groups. Pain measurements on the VAS scale were taken at each stage of the hysteroscopic procedure. After each stage, the operator asked the patient to indicate the maximum perceived pain value: after pericervical anesthesia was administered (VAS1), during the installation of equipment (between the removal of the speculum and the insertion of the hysteroscope into the vagina) (VAS2), after insertion of the hysteroscope and visualization of the external orifice of the cervical canal (VAS3), after passage of the hysteroscope through the cervical canal (VAS4), and after completion of the procedure in the uterine cavity (VAS5). The duration of each stage of the procedure was measured with a stopwatch: administration of pericervical anesthesia (T1), time between the removal of the speculum and the insertion of the hysteroscope into the vagina (T2), insertion of the hysteroscope into the vagina until the outer orifice of the cervical canal became visible (T3), passage of the hysteroscope through the cervical canal (T4), and the hysteroscopy procedure itself (T5). Results: The highest pain rating was for the canal passage stage (VAS4: 2.47 ± 2.48 points), followed by the procedure itself (VAS5: 2.12 ± 2.33 points). Anesthesia was also reported as quite painful, while the lowest pain was noted during the assembly stage. Overall pain scores for the entire procedure (VASmax) ranged from 3.5 ± 2.37. Conclusion: In conclusion, we found that the passage through the cervical canal was the most painful moment. Overall, hysteroscopy under pericervical anesthesia was not associated with significant pain. Special attention should be given to postmenopausal patients, as they experience more pain during the passage of the hysteroscope through the cervical canal. This group may benefit from additional pain management strategies during the procedure.

Background: Grossly bloody colostrum is defined as the presence of brownish or bloody-colored colostrum. The frequency is determined to be 0.1% of all births, and no predisposing factor for its occurrence was determined. The purpose of this study was to find factors that increase the probability of the syndrome and the possible influence of the presence of erythrocytes (red blood cells—RBCs) in breast milk on the symptoms of maternal milk intolerance in newborns. Methods: Here, 2 mL of colostrum was collected from 137 participants on postpartum days 1–3, separately from each breast, and transferred to the laboratory. For microscopic analysis, 0.5 mL of colostrum was centrifuged and then stained using the May–Grünwald–Giemsa method. Using an Olympus BX 43 light microscope at 400× total magnification, samples were visually assessed for the presence of RBCs. Additionally, the participants completed a questionnaire regarding their health status, observation of feeding tolerance of the newborn, observed milk color and other factors. Results: The number of RBCs in the yellow or white colostrum samples ranged from 8 to 1000 RBCs/mL and was found in 24.8% of cases. Regardless of the number of RBCs, the color of the milk was white (28.5%) or yellow (66.4%). Only one participant (0.7%) presented classical bloody-stained colostrum with visible bloody-milk colorization. We did not observe the influence of any analyzed factor as the reason for the increased number of RBCs in the colostrum. Conclusions: The presence of RBCs in breast milk did not cause milk intolerance among newborns and was independent of the analyzed factors. Mothers should be supported, and in view of the overall composition of breast milk, especially the content of immune cells in colostrum, even a temporary interruption in breast milk feeding in the case of grossly bloody colostrum is not recommended.

Pain accompanying medical procedures can be considered in the “mind-body” problem of accounting for and describing the relationship between mental and physical processes (psyche and soma). Background/Objectives: The purpose of this study is to evaluate the severity of pain among patients undergoing a minihysteroscopy procedure under local anesthesia using the “GUBBINI SYSTEM” (GUBBINI Mini Hystero-Resectoscope; Tontarra Medizintechnik, Tuttlingen, Germany) and to assess the association of various covariates with pain during the procedure, including patient emotional state. Methods: This study included 171 patients admitted to the Center for Hysteroscopy under Local Anesthesia at the Heliodor Święcicki Gynecological and Obstetrical Clinical Hospital of the Karol Marcinkowski Medical University in Poznań, Poland, for hysteroscopic treatment under local anesthesia (paracervical, using lignocaine). The Center for Hysteroscopy is the first certified “CENTER OF EXCELLENCE” of The International Society for Gynecologic Endoscopy (ISGE) in Poland. Results: A positive relationship was observed between alexithymia and its trait of difficulty identifying emotions and pain, as well as between perceived pain and one of the deficits of emotional processing—signs of unprocessed emotion. Conclusions: In conclusion, before the hysteroscopy, adequate information and counseling related to the procedure can effectively reduce the pain and anxiety levels of the women, and nurses can navigate this stressful process. Providing education and counseling to all women undergoing hysteroscopy, and explaining the procedure in detail, should be the preferred approach.

Pregnant women and their neonates belong to the group of individuals with elevated risk for COVID-19 infection. Data on the course of the disease and how it affects the pregnancy and neonatal wellbeing remain conflicting. The aim of the study was to evaluate the effect of SARS CoV-2 infection on the mode of delivery, neonatal condition and selected maternal and fetal laboratory parameters. This was a single-center retrospective case–control study. This dataset was generated using electronic medical records collected by medical personnel. Two groups of patients, hospitalized between April, 2020 and February, 2021, were included in the study: study group (304)—pregnant women with SARS-CoV-2 and control group (N = 329)—healthy pregnant women or parturients. Mothers with a severe course of COVID-19 had higher activated partial thromboplastin—APTT (p = 0.02), C-Reactive Protein—CRP (p = 0.00) and procalcitonin (p = 0.032) levels as compared to pregnant women with mild or moderate course of the disease. Neonates born to SARS-CoV-2-infected mothers presented with worse condition at 1 and 5 minutes of life (p = 0.000 and 0.00, respectively) and lower Arterial Blood Gas—ABG pH scores (p = 0.016). Elective cesarean section is the most common mode of delivery for SARS-CoV2-infected mothers. Emergency cesarean sections are performed at earlier gestational age as compared to vaginal delivery and elective cesarean section. Lower Apgar scores were observed in neonates born to SARS-CoV-2-infected mothers who required oxygen therapy and whose procalcitonin levels were elevated. There is a relationship between more severe course of COVID-19 and APTT, as well as CRP and procalcitonin levels.
