Reproducibility of colposcopy quality indicators-A survey among members of the European Federation for Colposcopy.

INTRODUCTION: Colposcopy is an important part of the diagnostic work-up of women with an abnormal cervical screening test as it is used to guide the collection of biopsies. Although quality assurance has been used in the evaluation of screening programs, not much is known about quality indicators for the diagnostics and treatment of screen-positive women. Therefore, the European Federation for Colposcopy developed quality indicators aiming to support colposcopy practice across Europe. We performed a survey of colposcopy cases to determine if the quality indicators are understandable, relevant, and reproducible. MATERIAL AND METHODS: We conducted a survey among all members of the European Federation for Colposcopy Quality and Standards Group from November 2022 to March 2023. Members were asked to collect information on a total of 17 quality indicators for 50 women who had been newly referred for colposcopy due to an abnormal screening test between January 1, 2020 to December 31, 2021. Results were reported descriptively. RESULTS: We included data on 609 cases from 12 members across Europe. The majority of the quality indicators were either achieved or within reach of the agreed standard, often due to few countries with outlying data. One quality indicator had very low performance, although stratified results indicated that two countries had different clinical management of the patient type thereby skewing the results. In addition, discrepancies between the number of cases included in each quality indicator raised concerns regarding potential misunderstanding of the quality indicator and its objective. CONCLUSIONS: Quality indicators on colposcopy must be understandable to those collecting data, highlighting the importance of validating quality indicators before data collection.

Day 5 versus day 3 embryo biopsy for preimplantation genetic testing for monogenic/single gene defects.

BACKGROUND: Assisted reproductive technology (ART) has allowed couples with a family history of a monogenic genetic disease, or a disease-carrying gene, to reduce the chance of them having a child with the genetic disorder. This is achieved by genetically testing the embryos using an advanced process called preimplantation genetic testing for monogenic or single gene disorders (PGT-M), such as Huntington's disease or cystic fibrosis. This current terminology (PGT-M) has replaced the formerly-known preimplantation genetic diagnosis (PGD). During PGT-M, one or more embryo cells are biopsied and analysed for genetic or chromosomal anomalies before transferring the embryos to the endometrial cavity. Biopsy for PGT-M can be performed at day 3 of cleavage-stage embryo development when the embryo is at the six- to the eight-cell stage, with either one or two blastomeres being removed for analysis. Biopsy for PGT-M can also be performed on day 5 of the blastocyst stage of embryo development when the embryo has 80 to 100 cells, with five to six cells being removed for analysis. Day 5 biopsy has taken over from day 3 biopsy as the most widely-used biopsy technique; however, there is a lack of summarised evidence from randomised controlled trials (RCTs) that assesses the effectiveness and safety of day 5 biopsy compared to day 3 biopsy. Since biopsy is an invasive process, whether it is carried out at day 3 or day 5 of embryo development may have different impacts on further development, implantation, pregnancy, live birth and perinatal outcomes. OBJECTIVES: To assess the benefits and harms of day 5 embryo biopsy, in comparison to day 3 biopsy, in PGT-M in women undergoing in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) cycles. SEARCH METHODS: We searched the following electronic bibliographic databases in December 2021 to identify relevant RCTs: the Cochrane Gynaecology and Fertility Group (CGFG) Specialised Trials Register; CENTRAL, MEDLINE, Embase and PsycINFO. We also handsearched grey literature, such as trial registers, relevant journals, reference lists, Google Scholar, and published conference abstracts. SELECTION CRITERIA: Eligible RCTs compared day 5 versus day 3 embryo biopsy for PGT-M.  DATA COLLECTION AND ANALYSIS: We used standard methodological procedures recommended by Cochrane. The primary review outcomes were live births and miscarriages. We calculated outcomes per woman/couple randomised and reported odds ratios (ORs) with 95% confidence intervals (CIs). MAIN RESULTS: We included one RCT involving 20 women. The evidence was of very low certainty; the main limitations of the study were serious risk of bias due to lack of blinding of study personnel, and imprecision. We are uncertain whether day 5 embryo biopsy compared to day 3 biopsy has an effect on live births (OR 1.50, 95% CI 0.26 to 8.82; 1 RCT, 20 women; very low-certainty evidence). The evidence suggests that if the chance of live birth following day 3 biopsy was assumed to be 40%, then the chance with day 5 biopsy is between 15% and 85%. It is also uncertain whether day 5 embryo biopsy compared to day 3 biopsy has an effect on miscarriages (OR 1.00, 95% CI 0.05 to 18.57; 1 RCT, 20 women; very low-certainty evidence).  We are uncertain whether day 5 embryo biopsy compared to day 3 biopsy has an effect on other secondary outcome measures, including viable intrauterine pregnancies (OR 2.25, 95% CI 0.38 to 13.47; 1 RCT, 20 women; very low-certainty evidence), ectopic pregnancies (OR 0.16, 95% CI 0.01 to 3.85; 1 RCT, 20 women; very low-certainty evidence), stillbirths (OR not estimable as no events in either group; 1 RCT, 20 women; very low-certainty evidence) or termination of pregnancies (OR 3.32, 95% CI 0.12 to 91.60; 1 RCT, 20 women; very low-certainty evidence). No studies reported on gestational age at birth, birthweight, neonatal mortality and major congenital anomaly. AUTHORS' CONCLUSIONS: We are uncertain if there is a difference in live births and miscarriages, viable intrauterine pregnancies, ectopic pregnancies, stillbirths or termination of pregnancies between day 5 and day 3 embryo biopsy for PGT-M. There was insufficient evidence to draw any conclusions regarding other adverse outcomes. The results should be interpreted with caution, as the evidence was of very low certainty due to limited studies, high risk of bias in the included study, and an overall low level of precision.

Transradial Embolization, an Underused Type of Uterine Artery Embolization Approach: A Systematic Review.

Background and Objectives: The most utilized approach for the embolization of uterine arteries is the transfemoral path. However, the transradial approach (TRA) has been gaining popularity among cardiologic interventions in the last years but only few studies have shown its applicability in uterine myoma treatment. The objective of this paper is to assess the feasibility, safety and efficacy of TRA when compared with the transbrachial, transulnar or transfemoral approach (TFA) for uterine arteries embolization (UAE). Materials and methods: A systematic review of the literature that analyzes the TRA for UAE it was carried out, in order to assess its safety and effectiveness. It was systematically searched the literature (Google Scholar, PubMed/MEDLINE, Cochrane Library and Embase) using the words ''uterine artery embolization''/''uterine embolization'' and ''transradial''/''radial''. All the relevant papers published until March 2020 were retrieved and analyzed. Results: Ten studies were considered eligible for this topic. TRA is a comparable method with TFA for uterine artery embolization. Conclusions: These studies allowed us to conclude that TRA is as safe and efficient as TFA. Its advantages include few complications, shorter hospitalization period, and rapid mobilization but a steeper learning curve has the disadvantage of a longer learning curve compared to TFA. Yet, these findings are built on few reports and more research is needed.

Strategically Constructed Bilayer Tin (IV) Oxide as Electron Transport Layer Boosts Performance and Reduces Hysteresis in Perovskite Solar Cells.

Nanostructured tin (IV) oxide (SnO2 ) is emerging as an ideal inorganic electron transport layer in n-i-p perovskite devices, due to superior electronic and low-temperature processing properties. However, significant differences in current-voltage performance and hysteresis phenomena arise as a result of the chosen fabrication technique. This indicates enormous scope to optimize the electron transport layer (ETL), however, to date the understanding of the origin of these phenomena is lacking. Reported here is a first comparison of two common SnO2 ETLs with contrasting performance and hysteresis phenomena, with an experimental strategy to combine the beneficial properties in a bilayer ETL architecture. In doing so, this is demonstrated to eliminate room-temperature hysteresis while simultaneously attaining impressive power conversion efficiency (PCE) greater than 20%. This approach highlights a new way to design custom ETLs using functional thin-film coatings of nanomaterials with optimized characteristics for stable, efficient, perovskite solar cells.

Uterine Artery Doppler Ultrasonography for First Trimester Prediction of Preeclampsia in Individuals at Risk from Low-Resource Settings.

Background and objectives: The objective of this study was to evaluate the potential of first trimester uterine artery Doppler ultrasonography for the early prediction of preeclampsia (PE), in at-risk pregnant women. Materials and Methods: This was a prospective longitudinal study, including 120 Caucasian pregnant women with risk factors for PE. The potential of pulsatility indexes (PI) and notch was assessed as a tool for preeclampsia screening. Results: Doppler examination of the uterine artery performed early at 11-14 WA allows the detection of pregnancies that will develop PE with a sensitivity of 61.5% and a specificity of 63.8% based on PI analysis. Predictive power increases slightly by adding bilateral notch (sensitivity = 65.4%; specificity = 66%). Conclusions: Uterine artery Doppler examination is an effective non-invasive screening test for the development of PE in pregnancies at risk, particularly appropriate in health systems with limited means of evaluating other biomarkers.

Spontaneous Heterotopic Pregnancy with Unaffected Intrauterine Pregnancy: Systematic Review of Clinical Outcomes.

Background and objective: Spontaneous heterotopic pregnancy (SHP) is a rare condition represented by the synchronous coexistence of an intrauterine and an ectopic pregnancy. It rarely occurs with natural conception and is usually a consequence of assisted reproductive techniques. Diagnosis of SHP can be a challenge for the clinician. The evolution of the intrauterine pregnancy is dependent on many factors, such as the location of the heterotopic pregnancy, gestational age at the time of diagnosis, the surgical procedure, the presence of other risk factors, early or delayed management. The aim of this systematic review of the literature was to extract existing evidence on spontaneous heterotopic pregnancy with otherwise unaffected intrauterine pregnancy. Materials and Methods: From a total of 1907 database entries identified in PubMed, EMBASE and Cochrane reviews, we selected 18 papers for narrative synthesis, for which we explored the diagnostic options, treatment, and outcome of these extremely rare epidemiologic occurrences. Manuscripts were assessed using the CARE guidelines for reporting case reports. Results: The main symptom was abdominal pain, and the preferred treatment approach was surgical, more precisely, using a laparoscopic approach. Most cases presented no risk factors, and the diagnosis was mostly made in the first semester. Conclusions: Normal follow-up and evolution of intrauterine pregnancy have been observed regardless of surgical approach (open or laparoscopic). Early diagnosis and treatment are advised, as they impact maternal and fetal outcomes. Evidence on this topic is scarce, predominantly comprised of case reports with variable degrees of adherence to dissemination guidelines. More studies on this topic are required to optimize care protocols for this type of pregnancy.

Endometrial resection and ablation techniques for heavy menstrual bleeding.

BACKGROUND: Heavy menstrual bleeding (HMB) is a significant health problem in premenopausal women; it can reduce their quality of life and can cause social disruption and physical problems such as iron deficiency anaemia. First-line treatment has traditionally consisted of medical therapy (hormonal and non-hormonal), but this is not always successful in reducing menstrual bleeding to acceptable levels. Hysterectomy is a definitive treatment, but it is more costly and carries some risk. Endometrial ablation may be an alternative to hysterectomy that preserves the uterus. Many techniques have been developed to 'ablate' (remove) the lining of the endometrium. First-generation techniques require visualisation of the uterus with a hysteroscope during the procedure; although it is safe, this procedure requires specific technical skills. Newer techniques for endometrial ablation (second- and third-generation techniques) have been developed that are quicker than previous approaches because they do not require hysteroscopic visualisation during the procedure. OBJECTIVES: To compare the efficacy, safety, and acceptability of endometrial destruction techniques to reduce heavy menstrual bleeding (HMB) in premenopausal women. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Group Specialised Register of controlled trials, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE, Embase, CINAHL, and PsycInfo (from inception to May 2018). We also searched trials registers, other sources of unpublished or grey literature, and reference lists of retrieved studies, and we made contact with experts in the field and with pharmaceutical companies that manufacture ablation devices. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing different endometrial ablation or resection techniques for women reporting HMB without known uterine pathology, other than fibroids outside the uterine cavity and smaller than 3 centimetres, were eligible. Outcomes included improvement in HMB and in quality of life, patient satisfaction, operative outcomes, complications, and the need for further surgery, including hysterectomy. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, assessed trials for risk of bias, and extracted data. We contacted study authors for clarification of methods or for additional data. We assessed adverse events only if they were separately measured in the included trials. We undertook comparisons with individual techniques as well as an overall comparison of first- and second-generation ablation methods. MAIN RESULTS: We included in this update 28 studies (4287 women) with sample sizes ranging from 20 to 372. Most studies had low risk of bias for randomisation, attrition, and selective reporting. Less than half of these studies had adequate allocation concealment, and most were unblinded. Using GRADE, we determined that the quality of evidence ranged from moderate to very low. We downgraded evidence for risk of bias, imprecision, and inconsistency.Overall comparison of second-generation versus first-generation (i.e. gold standard hysteroscopic ablative) techniques revealed no evidence of differences in amenorrhoea at 1 year and 2 to 5 years' follow-up (risk ratio (RR) 0.99, 95% confidence interval (CI) 0.78 to 1.27; 12 studies; 2145 women; I² = 77%; and RR 1.16, 95% CI 0.78 to 1.72; 672 women; 4 studies; I² = 80%; very low-quality evidence) and showed subjective improvement at 1 year follow-up based on a Pictorial Blood Assessment Chart (PBAC) (< 75 or acceptable improvement) (RR 1.03, 95% CI 0.98 to 1.09; 5 studies; 1282 women; I² = 0%; and RR 1.12, 95% CI 0.97 to 1.28; 236 women; 1 study; low-quality evidence). Study results showed no difference in patient satisfaction between second- and first-generation techniques at 1 year follow-up (RR 1.01, 95% CI 0.98 to 1.04; 11 studies; 1750 women; I² = 36%; low-quality evidence) nor at 2 to 5 years' follow-up (RR 1.02, 95% CI 0.93 to 1.13; 672 women; 4 studies; I² = 81%).Compared with first-generation techniques, second-generation endometrial ablation techniques were associated with shorter operating times (mean difference (MD) -13.52 minutes, 95% CI -16.90 to -10.13; 9 studies; 1822 women; low-quality evidence) and more often were performed under local rather than general anaesthesia (RR 2.8, 95% CI 1.8 to 4.4; 6 studies; 1434 women; low-quality evidence).We are uncertain whether perforation rates differed between second- and first-generation techniques (RR 0.32, 95% CI 0.10 to 1.01; 1885 women; 8 studies; I² = 0%).Trials reported little or no difference between second- and first-generation techniques in requirement for additional surgery (ablation or hysterectomy) at 1 year follow-up (RR 0.72, 95% CI 0.41 to 1.26; 6 studies: 935 women; low-quality evidence). At 5 years, results showed probably little or no difference between groups in the requirement for hysterectomy (RR 0.85, 95% CI 0.59 to 1.22; 4 studies; 758 women; moderate-quality evidence). AUTHORS' CONCLUSIONS: Approaches to endometrial ablation have evolved from first-generation techniques to newer second- and third-generation approaches. Current evidence suggests that compared to first-generation techniques (endometrial laser ablation, transcervical resection of the endometrium, rollerball endometrial ablation), second-generation approaches (thermal balloon endometrial ablation, microwave endometrial ablation, hydrothermal ablation, bipolar radiofrequency endometrial ablation, endometrial cryotherapy) are of equivalent efficacy for heavy menstrual bleeding, with comparable rates of amenorrhoea and improvement on the PBAC. Second-generation techniques are associated with shorter operating times and are performed more often under local rather than general anaesthesia. It is uncertain whether perforation rates differed between second- and first-generation techniques. Evidence was insufficient to show which second-generation approaches were superior to others and to reveal the efficacy and safety of third-generation approaches versus first- and second-generation techniques.

Pictorial essay of ultrasound-reconstructed coronal plane images of the uterus in different uterine pathologies.

Imaging in the major planes (horizontal, coronal, and sagittal) of the uterus is important for determining anatomy and allowing the findings to be standardized, and for evaluating and diagnosing different pathological conditions in clinical practice. Examination of the coronal plane is an important step in identifying uterine pathologies and their relationships to the endometrial canal. Three-dimensional (3D) ultrasound reveals the normal anatomy better and improves the depiction of abnormal anatomy, as the coronal plane of the uterus can easily be obtained using 3D reconstruction techniques. Our pictorial essay demonstrates that adding 3D ultrasound to a routine gynecological workup can be beneficial for clinicians, enabling a precise diagnosis to be made. In addition, the volumes obtained and stored by 3D ultrasound can allow students or residents to become more familiar with normal and abnormal pelvic structures. Clin.

Awareness and Knowledge About HPV and HPV Vaccine Among Romanian Women.

Cervical cancer is one of the most prevalent gynecological malignancies worldwide. Romania has the highest incidence of this type of cancer in Europe. A successful prevention strategy has to consider the primary prevention measures (including health education on human papilloma virus (HPV) infection but also vaccination). The aim of this study was to assess the knowledge and attitudes of Romanian women about HPV and HPV vaccine. We conducted a cross-sectional study survey of 454 women using an anonymously completed questionnaire covering the awareness and knowledge of HPV infection and attitudes to vaccination. We also analyzed the discussions and conclusion from a focus group of healthcare professionals regarding (1) HPV and HPV awareness and attitude, and (2) suggestions for improving HPV vaccine knowledge and acceptance. 69.2% of women were aware about HPV but their knowledge was minimal and incomplete. While 62.3% had heard about HPV vaccine, only 50.7% had a positive attitude toward it. The main barriers to vaccination were the fear of side effects, the perception that is risky, and the financial concerns. Deficiencies in knowledge were noted for vaccine, genital warts, or risks factors for HPV infection like the early onset of sexual life. The information regarding HPV and vaccine is not always accurate and complete, and only 50.7% of women have a positive attitude toward the vaccine. More educational programs and clearer communication are needed to raise awareness and knowledge regarding HPV and HPV vaccine.

Perception and use of Pap smear screening among rural and urban women in Romania.

Background: In 2012 the National Screening Program for all women between 25 and 64 years of age was launched in Romania. Public awareness is an important factor in the success of a screening program. For this reason, we intended to assess the perception and the level of awareness of Romanian women regarding the Pap test in the prevention of cervical cancer. Methods: A cross-sectional study was conducted among 454 women from rural and urban areas. For our study, we used a questionnaire covering general characteristics, awareness, knowledge and practices regarding cervical cancer and Pap smear. Results: 431 participants (95%) had heard of cervical cancer and Pap smear but only 71.8% knew the exact role of it. Bivariate analysis showed that knowledge about the importance of the Pap smear, early detection and treatment of early-stage cervical cancer was reduced among women with low socio-economic status, mainly living in rural area. The most frequent reasons for avoiding Pap smear screening were: lack of money, embarrassment or fear of gynaecological consultation and pain, the feeling that they don't need it, misconceptions about cervical cancer, fatalistic attitude, perceived low susceptibility to cervical cancer. Conclusions: Because the uptake and the success of cervical cancer screening are determined by women's knowledge and awareness of Pap smear, it is critical to improve these perceptions in the near future especially in rural area characterized by a low socio-economic status.

Orientation-tuned surround suppression in mouse visual cortex.

The firing rates of neurons in primary visual cortex (V1) are suppressed by large stimuli, an effect known as surround suppression. In cats and monkeys, the strength of suppression is sensitive to orientation; responses to regions containing uniform orientations are more suppressed than those containing orientation contrast. This effect is thought to be important for scene segmentation, but the underlying neural mechanisms are poorly understood. We asked whether it is possible to study these mechanisms in the visual cortex of mice, because of recent advances in technology for studying the cortical circuitry in mice. It is unknown whether neurons in mouse V1 are sensitive to orientation contrast. We measured the orientation selectivity of surround suppression in the different layers of mouse V1. We found strong surround suppression in layer 4 and the superficial layers, part of which was orientation tuned: iso-oriented surrounds caused more suppression than cross-oriented surrounds. Surround suppression was delayed relative to the visual response and orientation-tuned suppression was delayed further, suggesting two separate suppressive mechanisms. Previous studies proposed that surround suppression depends on the activity of inhibitory somatostatin-positive interneurons in the superficial layers. To test the involvement of the superficial layers we topically applied lidocaine. Silencing of the superficial layers did not prevent orientation-tuned suppression in layer 4. These results show that neurons in mouse V1, which lacks orientation columns, show orientation-dependent surround suppression in layer 4 and the superficial layers and that surround suppression in layer 4 does not require contributions from neurons in the superficial layers.

Intrauterine foreign bodies, other than contraceptive devices and systems, may affect fertility - report of two very different cases.

OBJECTIVES: To present two cases in which foreign bodies in the uterine cavity had a contraceptive effect for the duration of their presence in utero. CASE: One case of endometrial osseous metaplasia and another case with unabsorbed suture material after a caesarean section resulted in foreign bodies acting like an intrauterine contraceptive. Ultrasound was used to diagnose the conditions, and hysteroscopy to remove the foreign bodies. CONCLUSION: Foreign intrauterine bodies should be considered in cases of infertility.

Vitamin D-The Iceberg in Endometriosis-Review and Meta-Analysis.

(1) Background: Although vitamin D has many known biological effects, very little research has been conducted on how vitamin D may be related or play a role in endometriosis. The aim of our study was to perform an evaluation regarding vitamin D levels and possible implications in endometriosis through a statistical analysis of the data collected from the included studies. (2) Methods: For this review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and PubMed/Internet portal of the National Library of Medicine databases using several keywords related to our topic. (3) Results: Only nine articles were identified as complete or possessing the capacity to compute all available data. We totalized a number of 976 patients with endometriosis and 674 controls. From the nine studies included in our analysis, three of them claim there is no difference between women with and without endometriosis concerning 25(OH) vitamin D levels; however, the other six studies found significant differences regarding this aspect. (4) Conclusions: Our results underscored the complexity of analyzing the role of the vitamin D complex in a challenging condition like endometriosis and suggest that focusing on the tissue level might be essential to obtain accurate answers to our inquiries.

Epidemiology of Adverse Outcomes in Teenage Pregnancy-A Northeastern Romanian Tertiary Referral Center.

Background: Despite being a very well-documented subject in the literature, there are still conflicting results regarding teenage pregnancies and their fetal outcomes. Methods: We conducted a retrospective, comparative cohort study that included 1082 mothers aged less than 18 years, compared to 41,998 mothers aged over 18 years, who delivered in our tertiary referral center between January 2015 and December 2021. To check for significant differences between the two groups, the chi-qquared or Fisher's test for categorical variables were used. Results: We detected statistically significant higher rates of fetal malformation, premature birth, FGR and SGA fetal growth conditions, preeclampsia, condylomatosis and vaginal infection with E. coli in our cohort of teenagers. In this subpopulation of teenagers, the rate for premature birth at less than 32 weeks of gestation was 3.26-fold higher and 3.25-fold higher for condylomatosis, and these results referred to the cohort of adult patients (>18 years old) that gave birth in the same interval of time. Conclusions: Teenage pregnancies still remain a major health problem that burdens all countries worldwide regardless of their income. It needs solutions initially to prevent pregnancy in this young age segment and last but not least to improve both maternal and fetal outcomes.

Hydatidiform Mole-Between Chromosomal Abnormality, Uniparental Disomy and Monogenic Variants: A Narrative Review.

A hydatidiform mole (HM) or molar pregnancy is the most common benign form of gestational trophoblastic disease characterized by a proliferation of the trophoblastic epithelium and villous edema. Hydatidiform moles are classified into two forms: complete and partial hydatidiform moles. These two types of HM present morphologic, histopathologic and cytogenetic differences. Usually, hydatidiform moles are a unique event, but some women present a recurrent form of complete hydatidiform moles that can be sporadic or familial. The appearance of hydatidiform moles is correlated with some genetic events (like uniparental disomy, triploidy or diandry) specific to meiosis and is the first step of embryo development. The familial forms are determined by variants in some genes, with NLRP7 and KHDC3L being the most important ones. The identification of different types of hydatidiform moles and their subsequent mechanisms is important to calculate the recurrence risk and estimate the method of progression to a malign form. This review synthesizes the heterogeneous mechanisms and their implications in genetic counseling.

Vitamin D and Mitosis Evaluation in Endometriosis: A Step toward Discovering the Connection?

(1) Background: The effects of serum vitamin D levels, the vitamin D receptor (VDR), and phosphohistone H3 (PHH3) in endometriosis were investigated in two cohorts of women with this pathology: those receiving hormonal treatment and those without treatment. (2) Methods: In 60 cases of women with endometriosis (26 with progestin treatment and 34 without), paraffin-embedded endometriosis tissue samples retrieved after surgery were immunohistochemically (IHC) analyzed to determine the expression statuses of VDR and PHH3. In addition, serum levels of 25(OH) vitamin D were assessed for each patient. (3) Results: The serum 25(OH) vitamin D evaluations revealed higher levels of 25(OH) vitamin D in women with treatment compared with those without. The positive IHC indexes of VDR and PHH3 in these two groups were compared. Vitamin D receptor levels were positively correlated with PHH3 levels, both being increased in patients without treatment. (4) Conclusions: Serum 25(OH) vitamin D levels and IHC analysis of VDR and PHH3 can be used as additional tools for risk stratification and prognostic assessment in patients with endometriosis.

Effects of Progestin on Modulation of the Expression of Biomarkers in Endometriosis.

BACKGROUND: Our study aimed to examine the osteopontin (OPN) serum levels and tissue expression of CD44 and OPN in endometriosis-affected women both undergoing and not undergoing progestin treatment, and also to determine their involvement in the pathogenesis of endometriosis. METHODS: Using an ELISA kit, we evaluated the OPN serum levels of healthy and endometriosis-affected women both undergoing and not undergoing progestin treatment. Immunohistochemical (IHC) analyses were used to assess the endometriotic tissue expressions of CD44 and OPN. RESULTS: There were statistically significant higher OPN serum levels in the healthy control group compared to the women with endometriosis. Furthermore, there were higher OPN serum levels in the endometriosis-affected women undergoing the progestin treatment, but the difference did not reach statistical significance. In comparison to OPN, CD44 expression was significantly higher in all the endometriotic tissue glands and stroma, regardless of the patient's treatment status. Compared to the group receiving therapy, the OPN levels were higher in the endometriosis group not receiving therapy. OPN's robust cytoplasmic expression seemed to be associated with the non-treatment group. CONCLUSION: Endometriosis, CD44, and OPN appear to be closely related. This study suggests that endometriosis that has not been treated has an immunological profile distinct to endometriosis that has received treatment.

Mirroring Perinatal Outcomes in a Romanian Adolescent Cohort of Pregnant Women from 2015 to 2021.

Although the rates of adolescent pregnancies appear to have dropped according to the World Health Organization (WHO), the decrease in the age of the first menarche and better nutrition seems to contribute to the otherwise high rate of adolescent pregnancy worldwide, despite the efforts of different organizations to improve upon this trend. We conducted a population-based retrospective cohort study from January 2015 to December 2021 using our hospitals' database. We totaled 2.954 adolescent and 6.802 adult pregnancies. First, we compared younger adolescents' outcomes with those of older adolescents, as well as with adolescents aged between 18 and 19 years old; secondly, we compared adolescent pregnancies with adult ones. We detected higher percentages of cephalo-pelvic disproportion (43.2%), cervical dystocia (20.7%), and twin pregnancy (2.7%) in underage adolescents compared with 32%, 14.1%, and 1% in older underage adolescents, respectively, and 15.3%, 3.1%, and 0.6% in older ones. As teens became older, the likelihood of malpresentations and previous C-sections rose, whereas the likelihood of vaginal lacerations declined. When comparing adolescents with adult women, we found more cases that required episiotomy (48.1% compared with 34.6%), instrumental delivery (2.1% compared with 1%), and cervical laceration (10.7% compared with 8.4%) in the adolescent group, but the rates of malpresentation (11.4% compared with 13.5%), previous C-section (13.9% compared with 17.7%), and placenta and vasa praevia (4.5.6% compared with 14%) were higher in the adult women group. Adolescent pregnancy is prone to being associated with higher risks and complications and continues to represent a challenge for our medical system.
