A new method that facilitates the diagnosis of endometrial cancer: the ratio of endometrial thickness to the full thickness of the uterine wall and subcutaneous adipose tissue measurements.

Introduction: The aim of the present study was to investigate the association between some risk factors and endometrial pathologies determined by transvaginal sonography (TVS), as well as the diagnostic predictive values of serum oestradiol (E2) levels, subcutaneous adipose tissue (SAT) thickness, endometrium thickness (ET), and the ratio of ET to uterine wall full thickness (UWT) in differential diagnosis of malignant, precancerous, and benign pathologies of endometrium in patients with postmenopausal bleeding (PMB) or with asymptomatic increased endometrial thickness. Material and methods: The study was conducted with 211 women who applied to the hospital with complaints of PMB or ET of 5 mm or more in their routine controls. Venous blood samples were taken for complete blood count and the measurement of E2 levels. Patients also underwent TVS; ET, UWT, and the ratio of ET to UWT were measured. Results: Menopausal age and body mass index averages were significantly higher in atypical hyperplasia and endometrial cancer (EC) groups. Endometrial thickness and endometrial thickness/uterine wall full thickness ratio measured by TVS were significantly higher in all precancerous pathologies and EC. Subcutaneous adipose tissue thickness was significantly higher in all precancerous pathologies and EC. Oestradiol levels were higher in the atypical hyperplasia and EC groups. Conclusions: Postmenopausal bleeding is a common symptom of EC, but in some cases this disease may occur asymptomatically. Measurement of the endometrium thickness, and the ratio of endometrium thickness/uterine wall full thickness and SAT thickness by sonography has a high predictive value for this disease.

The relationship of immunohistochemical SOX-2 staining with histopathological diagnosis in patients with abnormal colposcopic findings.

This study aimed to analyze immunohistochemical staining and pathological data in cervical intraepithelial neoplasia (CIN) and squamous cell cervical carcinoma (SCC) with abnormal colposcopic findings. A histopathological evaluation of 45 low-grade squamous lesions (LSILs), 177 high-grade squamous lesions (HSILs) and 16 SCC biopsy materials from existing slides was obtained from blocks obtained from the archive. In addition, SOX-2 immunohistochemical staining was evaluated. The mean age of the HSIL group was 43.20 ± 8.97 years, younger than the mean age of the LSIL group of 51.62 ± 9.64 years (p = 0.000). There was no difference between the groups regarding the method of biopsy (p > 0.05). Endocervical gland involvement was not observed in the LSIL group, but was observed in 66 (37.3%) biopsy materials in the HSIL group (p = 0.000). There was a difference between the groups in terms of the level of CIN at the surgical margin (p = 0.000). Ki-67, SOX-2 staining percentage and p16INK4a positivity were higher in the HSIL group than in the LSIL group (respectively, 67.57 ± 19.10 vs. 14.62 ± 7.11, p = 0.000; 27.72 ± 31.56 vs. 10.09 ± 15.38, p = 0.003; 66 (82.5%) vs. 8 (44.4%), p = 0.001). While there was no difference in SOX-2 intensity between the HSIL and LSIL groups (p > 0.05), it was statistically significantly higher in the SCC group (p = 0.000), as was the percentage of SOX-2 (p = 0.000). We have shown that p16INK4a and SOX-2 staining is useful, in addition to Ki-67 immunostaining, which is widely used for SCC, which is one of the preventable cancer types. In addition, SOX-2 may provide a glimmer of hope in the development of SCC treatment modalities, especially since it is aggressively elevated in SCC rather than CIN lesions.

Polycystic Ovary Syndrome and Exercise: Evaluation of YouTube Videos.

OBJECTIVES: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in the reproductive female population. These young patients often and easily watch YouTube videos on the Internet to learn about their condition and find a natural solution. Our goal is to analyze the contents of PCOS exercise videos. METHODS: In July 2022, research data were collected by typing the term "PCOS exercise" in the search tab on the incognito YouTube page. One hundred and ninety eight videos that met the inclusion criteria were analyzed in detail. The basic data of the videos available on YouTube was recorded. In addition, the DISCERN, global quality score (GQS), and video power index (VPI) scoring systems were calculated by two independent researchers. RESULTS: The profiles of the video uploaders were: health employee 28 (14.1%), nutritionist 25 (12.6%), sports trainer 48 (24.2%), patient 21 (10.6%), undefined 76 (38.4%), and their countries were: India 91 (46%), Europe and England 36 (18.2%), USA and Canada 54 (27.3%), and other countries 17 (8.6%). The distribution of video content was yoga 58 (29.3%), aerobic exercise 38 (19.2%), strengthening exercise 44 (22.2%), and unified 58 (29.3%). The mean values were: video duration (15.27±11.27), total views (3,070,957±16,474,197), likes (48,116±283,308), dislikes (930±4102), VPI (97.82±7.28), GQS (3.89±1.05), DISCERN (33.62±10.42), subscriber counts (985,614±2,222,354), and comment counts (1741±10,689). Europe-England and America-Canada videos were of better quality for DISCERN and GQS scores than those from other countries. CONCLUSION: Overcoming PCOS requires a lifestyle change, including exercise and diet. There is no consensus on which type of exercise is better yet. However, the necessity of regular exercise is known. We showed yoga and Indian hegemony in YouTube "PCOS exercise" videos.

Microarray expression results of VEGF, YAP1 and PTEN immunostains in preeclampsia cases.

We aimed to evaluate the expression of YAP1, PTEN, VEGF in the placentas of patients with preeclampsia and placentas of healthy pregnant women for trophoblast invasion, which is similar to cancer etiopathogenesis. The placentas of 70 women who gave birth, including 30 preeclampsia and 40 healthy controls, were evaluated. YAP1, PTEN and VEGF immunohistochemical staining were performed using the microarray method on placental tissue. The mean ± standard deviation for YAP1, PTEN and VEGF intensity were; 1.57 ± 0.71,2.59 ± 0.80, 1.61 ± 0.59, respectively. PTEN intensity was statistically significantly lower in the preeclampsia group than in the control group (2.37 ± 0.99 vs 2.75 ± 0.58, p = .049). There was no difference between the groups in terms of YAP1 and VEGF staining (p > .05). The etiopathogenesis of preeclampsia is still unclear. However, since trophoblast invasion and endothelial repair have similar aspects with cancer mechanisms, both preeclampsia and cancer studies are progressing by supporting each other. Our study is a prototype study showing that large-participation studies can be carried out easily by using the microarray method as an economic model.

Relationship Between Immunohistochemical CD3, CD4, CD5, CD8, and PD1 Staining and Histopathological Diagnosis of Cervical Lesions in Patients With Abnormal Colposcopic Findings.

INTRODUCTION: This study aimed to analyse the relationship between clinicopathological factors in cervical intraepithelial lesions and abnormal colposcopic findings. MATERIAL AND METHODS: Thirty high-grade squamous intraepithelial lesion (HSIL) and thirty low-grade squamous intraepithelial lesion (LSIL) patients who underwent biopsy due to abnormal colposcopic findings were included in the study. The immunoreactivity of CD3, CD4, CD5, CD8, and PD-1 was analysed immunohistochemically in tumor-infiltrating lymphocytes (TILs) and stromal lymphocytes. RESULTS: In TILs, CD3, CD4, CD5, CD8, and PD-1 were highly stained in 20/30 (66.6%), 16/30 (53.3%), 15/30 (50.0%), 24/30 (80.0%), and 13/30 (43.3%) of the cases for the HSIL group, while 7/30 (23.3%), 4/30 (13.3%), 5/30 (16.6%), 9/30 (30.0%), and 5/30 (16.6%) were in the LSIL group, respectively. CD3, CD4, CD5, CD8, and PD-1 immunostainings for TILs were higher in the HSIL group (p=0.001, p=0.001, p=0.006, p˂0.001, p=0.024, respectively). Only PD-1 was significantly higher in lymphocytes in the stroma (p=0.001). CONCLUSIONS: CD3, CD4, and CD8 also show a positive correlation with the Ki-67 proliferation index. CD3, CD4, CD5, and CD8 may contribute to PD-1-mediated tumour control. Immunohistochemical staining plays a key role in evaluating the tumour microenvironment.

CD97 expression level and its effect on cell adhesion in Preeclampsia.

OBJECTIVES: Cellular interactions and cell adhesion underlie preeclampsia (PE). The aim of the current study is to investigate the role of cell adhesion molecules such as CD97, neural (N)-cadherin, epithelial (E) -cadherin and integrin beta-4 in PE. METHODS: This prospective study included 20 pregnant women with PE and a control group of 16 healthy pregnant women who were matched for age, gestational age, gravida and parity. Standard blood tests and placental cell adhesion molecule immunohistochemical staining were examined. RESULTS: The creatinine, uric acid and lactate dehydrogenase (LDH) levels from standard blood tests were found to be statistically higher in the PE group (p = 0.002, p = 0.000, p = 0.001; respectively). In the PE group, the CD97 maternal serum level was statistically significantly lower, as was its immunohistochemical expression in placental sections (p = 0.028, p = 0.000; respectively). The E-cadherin expression score was statistically higher in the PE group compared to the control group (3,65 ± 1,84 vs 2,06 ± 1,76 respectively; p = 0.003). The N-cadherin expression score was statistically lower in the PE group compared to the control group (1,50 ± 0,82 vs 2,43 ± 1,59 respectively; p = 0.049). Integrin beta-4 was not statistically different between groups. CONCLUSIONS: Cellular interaction may be responsible for PE as in cancer. A balance in intercellular communication, as researched in cancer therapy, may offer the solution in PE.

Analysis of YouTube Videos on Pregnant COVID-19 Patients During the Pandemic Period.

OBJECTIVE: Pregnant women often refer to YouTube videos when they are worried about themselves and/or their baby. This study aims to evaluate COVID-19 and pregnancy-related content on YouTube, the platform that comes to mind first when social media is mentioned. METHODS: YouTube videos were evaluated between September 7-10, 2022. "COVID-19 pregnancy" videos with more than 100.000 views were included in the study. The content and technical data of 45 videos were recorded. The videos were scored using the DISCERN score, Video Power Index (VPI), and Global Quality Scale (GQS). RESULTS: Of the 45 videos with a mean duration of 432 seconds, 32 (71.1%) of them originated in the USA, 38 (84.4%) of them were presented by healthcare workers, and 36 (80.0%) of them recommended vaccination. Accounts producing the videos had a mean of 3,037,619 subscribers. The videos we analyzed were viewed a mean of 522836 times. These videos had 9287 likes and 1891 comments. The DISCERN, VPI, and GQS mean scores of the videos were 32.36, 74.76, and 3.82, respectively. CONCLUSION: In order to correctly inform society about health problems, healthcare workers must make presentations on YouTube with a controlled mechanism. There is confusion about information on the internet, and people must acquire information selectively.

Severe Preeclampsia is Associated with Functional and Structural Cardiac Alterations: A Case-control Study.

BACKGROUND: The aim of the current study is to compare electrocardiographic and echocardiographic changes in patients with severe preeclampsia (PE) and those with uncomplicated pregnancies. METHODS: This is a case-controlled prospective study consisting of 21 pregnant women with severe preeclampsia and a control group consisting of age- and gestational age-matched 24 healthy pregnant women. All patients underwent electrocardiographic and echocardiographic investigation. RESULTS: QRS intervals were shorter and PR intervals were longer in the PE group (QRS duration: 80 (60-120) ms and 80 (40-110) ms, p=0.035; PR duration: 160 (100-240) ms and 120 (80-200) ms, respectively; p=0.046). The left ventricular end-systolic diameters of the patients with severe PE group were significantly larger than the control group (31 (24-36) mm and 30 (24-33) mm, respectively; p=0.05). Similarly, posterior wall thickness values of the PE group were significantly higher compared to the control group (9 (7-11) mm vs. 8 (6-10) mm, respectively; p=0.020). Left ventricular mass (146.63±27.73 g and 128.69±23.25 g, respectively; p=0.033) and relative wall thickness values (0.385±0.054 and 0.349±0.046, respectively; p=0.030) were also higher in the PE group. In addition, patients with early-onset severe PE had significantly a higher left ventricular end-diastolic diameter and volume compared with late-onset PE patients. CONCLUSIONS: The structural changes detected in the severe PE group suggest a chronic process rather than an acute effect. In addition, diastolic dysfunction and left ventricular remodeling are most marked in patients with severe early-onset PE.

The relation of CD3, CD4, CD8 and PD-1 expression with tumor type and prognosis in epithelial ovarian cancers.

OBJECTIVES: Ovarian cancer is a heterogeneous disease, where chronic inflammation plays a key role in carcinogenesis. In this study, it is aimed to analyze the relationship with prognosis and chemotherapy response to clinicopathologicalnvariables in epithelial ovarian cancers such as proliferation of PD-1 +, CD8 +, CD4 +, CD3 + T-lymphocytes infiltrating the tumor and tumor stroma. MATERIAL AND METHODS: Seventy-six cases diagnosed with primary epithelial ovarian tumor from biopsy or surgical resection materials were included in the study. Immunreactivity of CD3, CD4, CD8, PD1 was evaluated immunohistochemically in lymphocytes in tumor infiltrating lymphocytes and stromal lymphocytes. RESULTS: Seventeen (22.4%) of the cases were Type I, 59 (77.6%) of them were Type II ovarian carcinoma. PD-1 positivity was observed in stromal and intraepithelial lymphocytes in 22 (28.9%) of 76 cases. In the presence of PD-1 + T-lymphocytes that infiltrate tumor and stroma, disease-free survival are shorter (p = 0.037). The presence of stromal CD4 + and CD8 + T-lymphocytes was more common in late stage patients (p = 0.012, p = 0.036; respectively). The disease-free and overall survival rate was statistically significantly shorter in the presence of CD8 + T lymphocytes (p = 0.009, p = 0.003; respectively). CONCLUSIONS: CD3, CD4 and CD8 may contribute to PD-1 mediated tumor control. Anti PD-1 therapy may be an alternative to chemotherapy in PD-1 positive patients. Identifying patients who do not respond to chemotherapy through PD-1 expression prior to immunotherapy will help develop potential personalized immunotherapy.

Predictors of Human papillomavirus (HPV) persistence after treatment of high grade cervical lesions; does cervical cytology have any prognostic value in primary HPV screening?

OBJECTIVE: This study aimed to determine the factors associated with Human Papillomavirus (HPV) persistence in women undergoing cervical excision for pre-invasive lesions, after they have been referred from a primary HPV screening program. METHODS: A retrospective study design involving patients who were treated at a Cervical Disease Screening and Treatment Unit, in a university hospital setting. After initial treatment, cervical HPV infection status was analyzed at the sixth month, first year and then subsequently after the second year. RESULTS: Totally, 395 patients who were diagnosed with pre-invasive cervical lesions and who subsequently undergone cervical excision were identified. In the first-year visit after cervical excision, HPV 18 was cleared in almost all (95.8%) cases, followed by HPV 16 (69.9%) and other hrHPV types (65.6%). Available data documented that 88.6% of women reached clearance after the two-year follow-up. Univariate analysis revealed a significantly higher proportion of HPV clearance among women who were younger (p = 0.019), premenopausal (p = 0.002), and who had been found to have a negative cytology result on their initial Pap test (p = 0.018). However, only cervical cytology result remained as the independent predictor of HPV persistence on a multivariate logistic regression (OR 0.43; 95% CI 0.21-0.87; p = 0.019). CONCLUSIONS: A low risk of HPV persistence was found among every HPV genotype in women undergoing cervical excision for pre-invasive cervical lesions. Initial cervical cytology result was the only independent predictor of HPV clearance during surveillance, which indicates the prognostic value of Pap test in primary HPV screening.
