RESUMO
BACKGROUND: Demystifying the events around early pregnancy is challenging. A wide network of mediators and signaling cascades orchestrate the processes of implantation and trophoblast proliferation. Dysregulation of these pathways could be implicated in early pregnancy loss. There is accumulating evidence around the role of Wnt pathway in implantation and early pregnancy. The purpose of this study was to explore alterations in the expression of Wnt4, Wnt6 and ß-catenin in placental tissue obtained from human first trimester euploid miscarriages versus normally developing early pregnancies. METHODS: The study group consisted of first trimester miscarriages (early embryonic demises and incomplete miscarriages) and the control group of social terminations of pregnancy (TOPs). The placental mRNA expression of Wnt4, Wnt6 and ß-catenin was studied using reverse transcription PCR and real time PCR. Only euploid conceptions were included in the analysis. RESULTS: Wnt4 expression was significantly increased in placental tissue from first trimester miscarriages versus controls (p = 0.003). No significant difference was documented in the expression of Wnt6 (p = 0.286) and ß-catenin (p = 0.793). There was a 5.1fold increase in Wnt4 expression for early embryonic demises versus TOPs and a 7.6fold increase for incomplete miscarriages versus TOPs - no significant difference between the two subgroups of miscarriage (p = 0.533). CONCLUSIONS: This is, to our knowledge, the first study demonstrating significant alteration of Wnt4 expression in human placental tissue, from failed early pregnancies compared to normal controls. Undoubtedly, a more profound study is needed to confirm these preliminary findings and explore Wnt mediators as potential targets for strategies to predict and prevent miscarriage.

BACKGROUND: Even though polycystic ovary syndrome (PCOS) is a common reproductive disorder affecting young women, its impact on their sexual health is not well known. AIM: To examine the different aspects of female sexuality in young women with PCOS and attempt to associate hormonal changes and ovulatory status with their sexual function. METHODS: Anthropometric characteristics, hormonal levels and sexual function based on the Female Sexual Function Index (FSFI) questionnaire were assessed in 76 young women with PCOS and 133 matched controls. OUTCOMES: Sexual function is significantly impaired in young women with PCOS. RESULTS: Women with PCOS demonstrated lower scores than controls in arousal (5.04 ± 1.19 vs 4.48 ± 1.44, P < .001), lubrication (5.29 ± 1.17 vs 4.69 ± 1.54, P < .001), orgasm (4.78 ± 1.40 vs 4.11 ± 1.61, P = .001), satisfaction (5.22 ± 1.10 vs 4.78 ± 1.31, P = .016), and total score of the FSFI (29.51 ± 5.83 vs 26.76 ± 6.81, P < .001), even after correction for BMI. When corrected for total testosterone, the domains of lubrication, satisfaction, and total score of FSFI remained significantly impaired in women with PCOS (P values .037, .024, & .044 respectively). In multivariate logistic regression analysis, after adjusting for the effect of BMI and hormone levels, dysfunction in orgasm, satisfaction and the total FSFI score were still 3-4 times more common in PCOS (adjusted OR [95% CI]: 3.54, P = .020; 2.96, P = .050; 3.87, P = .027). Even though no statistically significant differences were observed between women with ovulatory PCOS and controls, we detected statistically significant differences in all domains of sexual function apart from pain between controls and PCOS women with anovulation (desire P value .04, arousal P value <.001, lubrication P value <.001, orgasm P value .001, satisfaction P value .001 and FSFI total score P value <.001). CLINICAL IMPLICATIONS: Women with PCOS have compromised sexual function, which is independent of their BMI and highly dependent on their ovulatory status. STRENGTHS AND LIMITATIONS: This is the first study in women with PCOS that implicates anovulation as a risk factor for sexual impairment in PCOS. Further studies are needed to elucidate the mechanisms implicated and to examine the effect of PCOS therapy on the patients' sexual function. CONCLUSION: The adverse effect of PCOS status on the female sexual function is independent of BMI and only partially dependent on hormonal changes characterizing the syndrome. Anovulation appears to be the major determinant of sexual impairment among women with PCOS. Mantzou D, Stamou MI, Armeni AK, et al.

Current research suggests that polycystic ovary syndrome (PCOS) might originate in utero and implicates the placenta in its pathogenesis. Kisspeptin (KISS1) and neurokinin B (NKB) are produced by the placenta in high amounts, and they have been implicated in several pregnancy complications associated with placental dysfunction. However, their placental expression has not been studied in PCOS. We isolated mRNA after delivery from the placentae of 31 PCOS and 37 control women with term, uncomplicated, singleton pregnancies. The expression of KISS1, NKB, and neurokinin receptors 1, 2, and 3 was analyzed with real-time polymerase chain reaction, using ß-actin as the reference gene. Maternal serum and umbilical cord levels of total testosterone, sex hormone-binding globulin (SHBG), free androgen index (FAI), androstenedione, dehydroepiandrosterone sulfate (DHEAS), Anti-Mullerian hormone (AMH), and estradiol were also assessed. NKB placental mRNA expression was higher in PCOS women versus controls in pregnancies with female offspring. NKB expression depended on fetal gender, being higher in pregnancies with male fetuses, regardless of PCOS. NKB was positively correlated with umbilical cord FAI and AMH, and KISS1 was positively correlated with cord testosterone and FAI; there was also a strong positive correlation between NKB and KISS1 expression. Women with PCOS had higher serum AMH and FAI and lower SHBG than controls. Our findings indicate that NKB might be involved in the PCOS-related placental dysfunction and warrant further investigation. Studies assessing the placental expression of NKB should take fetal gender into consideration.
RESUMO
PURPOSE: Neoangiogenesis is necessary for adhesion and invasiveness of endometriotic lesions in women affected by endometriosis. Vascular endothelial growth factor (VEGF) is one of the main components of angiogenesis and is part of the major pathway tissue factor (TF)-protease activated receptor-2 (PAR-2)-VEGF that leads to neoangiogenesis. Specificity protein 1 (SP1) is a transcriptional factor that has recently been studied for its crucial role in angiogenesis via a specific pathway. We hypothesize that by blocking angiogenetic pathways we can suppress endometriotic lesions. Gonadotrophin-releasing hormone-agonists (GnRH-a) are routinely used, especially preoperatively, in endometriosis. It would be of great interest to clarify which angiogenetic pathways are affected and, thereby, pave the way for further research into antiangiogenetic effects on endometriosis. METHODS: We used quantitative real-time polymerase chain reaction (qRT-PCR) to study mRNA expression levels of TF, PAR-2, VEGF, and SP1 in endometriotic tissues of women who underwent surgery for endometriosis and received GnRH-a (leuprolide acetate) preoperatively. RESULTS: VEGF, TF, and PAR-2 expression is significantly lower in patients who received treatment (p < 0,001) compared to those who did not, whereas SP1 expression is not altered (p = 0.779). CONCLUSIONS: GnRH-a administration does affect some pathways of angiogenesis in endometriotic lesions, but not all of them. Therefore, supplementary treatments that affect the SP1 pathway of angiogenesis should be developed to enhance the antiangiogenetic effect of GnRH-a in patients with endometriosis.

RESUMO
We report a rare case of spontaneous uterine rupture of an unscarred uterus caused by adenomyosis in the early third trimester. A 33-year-old primigravid woman was referred to our department because of severe acute abdominal pain and signs and symptoms of hemorrhagic shock. Ultrasound exanimation performed at admission revealed a living, intrauterine fetus of 28 weeks gestational age with reduced amniotic fluid and presence of free peritoneal fluid. The fetal heart rate was non-reassuring with variable decelerations and severe fetal bradycardia. Emergency cesarean section revealed massive hemoperitoneum and complete rupture in the uterine fundus. Subtotal peripartum hysterectomy with conservation of adnexae was performed. Histological examination revealed adenomyosis at the site of uterine rupture.

The clinical management of COVID-19 in pregnant women, who are considered a vulnerable population, remains uncertain even as the pandemic subsides. SARS-CoV-2 affects pregnant individuals in multiple ways and has been associated with severe maternal morbidity and mortality, as well as neonatal complications. The unique anatomy and physiology of gestation make managing COVID-19 in this population a complex and challenging task, emphasizing the importance of spreading knowledge and expertise in this area. Therapeutic interventions require distinct clinical consideration, taking into account differences in pharmacokinetics, vertical transmission, drug toxicities, and postnatal care. Currently, there is limited data on antiviral and immunomodulating COVID-19 pharmacotherapy in pregnancy. Some medication has been shown to be safe and well tolerated among pregnant women with COVID-19; however, the lack of randomized clinical trials and studies in this patient population is evident. Available vaccines are considered safe and effective, with no evidence of harm to the fetus, embryo development, or short-term postnatal development. Pregnant women should be counseled about the risks of SARS-CoV-2 infection and informed of available ways to protect themselves and their families. Effective treatments for COVID-19 should not be withheld from pregnant individuals, and more research is needed to ensure the best outcomes.

Aromatase inhibitors (AIs) provide an alternative to tamoxifen as an adjuvant therapy for post-menopausal, hormone-receptor positive breast cancer patients. The aim of the present study was to evaluate the effect of PvuII and XbaI polymorphisms of the ERα gene at ΑΙs treatment's adverse effects in post-menopausal women with breast cancer. The study included 87 post-menopausal women with ER-positive breast cancer treated with AIs and 80 healthy controls. The overall presence of ERα polymorphisms in all women with breast cancer was not different from the healthy controls. Endometrial thickness under AIs treatment was reduced from (mean value ± SD) 6,404 ± 2,901 mm to 3,666 ± 1,4656 mm. Moreover, the AA XbaI genotype was associated with greater reduction in endometrial thickness during therapy with AIs (p = 0.005). The presence of the CC PvuII and the AA XbaI genotypes were associated with elevated LDL levels and elevated triglycerides. In conclusion, the results of the present study showed that the genotype of women with breast cancer under AIs treatment might influence treatment's adverse effects, as, the presence of the CC PvuII and the AA XbaI genotypes of the ERα were associated with elevated LDL and triglycerides serum levels, while the AA XbaI genotype was associated with a greater reduction in endometrial thickness.

PURPOSE: The aim was to assess the expression stability of three commonly used reference genes, namely, ß-actin (ACTB), 18S ribosomal RNA (18S), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH), in placental tissue obtained from pregnant women with polycystic ovary syndrome (PCOS) and healthy controls. METHODS: mRNA was isolated after delivery from the placentae of 10 PCOS and 10 control women with term, uncomplicated, singleton pregnancies. The expression of ACTB, 18S, and GAPDH was analyzed using real-time polymerase chain reaction (RT-PCR). Gene expression stability was evaluated with the RefFinder, GeNorm, Normfinder, BestKeeper, and Delta-Ct tools. RESULTS: ACTB was ranked as the most stably expressed gene, followed by 18S. The expression of GAPDH varied considerably in both studied groups, while it was increased in PCOS versus controls (5.3-fold, p < 0.05). CONCLUSIONS: ACTB is an appropriate reference gene for placental gene expression studies in women with PCOS, whereas GAPDH is unfit for such a role, as its placental expression is increased in PCOS.

PURPOSE: Teenage pregnancies have consistently been associated with preterm labor in a wide range of studies. Evidence regarding the incidence and potential complications of teenage pregnancies in Greece is at present scarce. The aim of this study was to evaluate the perinatal outcomes as well as the risk of perinatal and obstetric complications of teenage pregnancies. METHODS: This retrospective study was conducted at the Department of Obstetrics and Gynecology of the University Hospital of Patras, Greece, and all data recorded concerned the year 2019 (January-December). We retrospectively reviewed 643 cases of singleton pregnancies divided into two groups, as follows: Group A included women of average maternal age (AMA) (20-34 years old), and Group B included teenagers, defined as women less than 20 years old. Data regarding demographic and pregnancy characteristics as well as obstetric and neonatal complications were collected. RESULTS: Teenage pregnancies accounted for 6.7% of all deliveries. We detected significantly higher rates of preterm births (p = 0.025), primiparity (p < 0.001), and negative marital status (p < 0.001) in teenage mothers compared to pregnant women of AMA. There were no significant differences concerning other factors between the two groups. CONCLUSIONS: The findings of the present study raise concern regarding the perinatal, obstetric, and social consequences of teenage pregnancies in Greece. Extended studies that will include further information on antenatal care and detailed socioeconomic factors (i.e., level of education, income, and ethnicity) are required to formulate reliable conclusions concerning teenage pregnancies and their effect on maternal and neonatal health.

OBJECTIVES: To investigate the influence of 6 months of treatment with an oral contraceptive (OC) containing 35 µ g ethinyl estradiol and 2 mg cyproterone acetate on plasma viscosity (PV) in young women with polycystic ovary syndrome (PCOS). DESIGN: Patients with PCOS were assessed for PV before and after 6 months of treatment with an OC containing 35 µg ethinyl estradiol and 2 mg cyproterone acetate. PV was determined by a viscometer Type 53610/I SCHOTT-Instruments, Mainz at 37°C. SETTINGS: Subjects were recruited from the Department of Obstetrics and Gynaecology, Division of Reproductive Endocrinology at the University Hospital of Patras, Greece. PATIENTS: The study included 66 young women with PCOS. MAIN OUTCOME MEASURES: PV. RESULTS: In PCOS women as a whole, PV at baseline was 1.249 ± 0.049 mm(2)/s (n = 66). After 6 months of treatment with an OC containing 35 µg ethinyl estradiol and 2 mg cyproterone acetate, PV was increased to 1.268 ± 0.065 mm(2)/s (p = 0.038). The difference between PV before and after 6 months of treatment with an OC containing 35 µg ethinyl estradiol and 2 mg cyproterone acetate (Δviscosity) was 0.01864 ± 0.071452 mm(2)/s. ΔViscosity was related to ?fibrinogen (r = 0.270, p = 0.046), to Δhematocrit (r = 0.514, p = 0.09) and to Δtriglycerides (r = 0.292, p = 0.021). CONCLUSION: Young women with PCOS presented an increased PV under OC treatment with 35 µg ethinyl estradiol and 2 mg cyproterone acetate.

The management of growth-restricted fetuses requires accurate diagnosis to optimize the timing of delivery. Doppler velocimetry is the only noninvasive method for assessing the fetoplacental hemodynamic status. This review will give a critical overview of the current knowledge on fetal venous blood flow in pregnancies complicated by in-trauterine growth-restricted fetuses. Adaptation of the circulation in intrauterine growth-restricted fetuses is described. Normal and abnormal venous Doppler waveforms are presented. Correlations of abnormal waveforms with the presence of acidemia and perinatal outcomes are emphasized. Limitations of venous Doppler velocimetry for optimizing the time for delivery and the perinatal outcome are also presented.

IMPORTANCE: Irrespective of the precise mechanisms leading to endometriosis, angiogenesis is essential for the establishment and long-term proliferation of the disease. As current surgical and medical management options for women with endometriosis have substantial drawbacks and limitations, novel agents are needed and molecules targeting the angiogenic cascade could serve as potential candidates. OBJECTIVE: Our aim was to review current data about the role of angiogenesis in the pathophysiology of endometriosis and summarize the novel antiangiogenic agents that could be potentially used in clinical management of patients with endometriosis. EVIDENCE ACQUISITION: Original research and review articles were retrieved through a computerized literature search. RESULTS: Loss of balance between angiogenic activators and suppressors triggers the nonphysiological angiogenesis observed in endometriotic lesions. Several proangiogenic mediators have been identified and most of them have demonstrated increased concentrations in the peritoneal fluid and/or serum of women with endometriosis. Among the antiangiogenic molecules, anti-vascular endothelial growth factor agents, dopamine agonists, romidepsin, and statins have shown the most promising results so far. CONCLUSIONS AND RELEVANCE: Given the limitations of current treatments of endometriosis, there is a need for novel, more efficient agents. Antiangiogenic molecules could be used potentially in clinical management of women with endometriosis; however, their safety and efficiency should be carefully assessed prior to that. Further large prospective trials in humans are needed before any treatment is introduced into daily clinical practice.

PURPOSE: The aim of the present study was to determine the prevalence and association of the G972S polymorphism of the insulin receptor substrate-1 gene (IRS-1 G972S SNP) with polycystic ovary syndrome (PCOS) and insulin resistance-related traits in a distinct phenotypic group of lean PCOS women with biochemical hyperandrogenemia, excluding obesity, which is considered to be an aggravating parameter of insulin resistance. METHODS: The study included 162 women with PCOS and 122 regularly menstruating, ovulatory women as controls. Physical measurements included weight, height, fat-free mass, fat mass, systolic and diastolic blood pressure and resting heart rate. Biochemical parameters included the serum testosterone, free testosterone, androstenedione, total cholesterol, triglycerides, HDL and LDL cholesterol and glucose levels. Insulin resistance was assessed by determining fasting insulin levels, fasting glucose levels, the fasting glucose/insulin ratio, as well as the HOMA and QUICKI indexes. All DNA samples were genotyped by a PCR-restriction fragment length polymorphism (RLFP) assay. RESULTS: No association of the genotype frequencies of the G972S polymorphism in insulin receptor substrate-1 gene (IRS-1 G972S SNP) with PCOS phenotype and insulin resistance was detected. CONCLUSION: The G972S polymorphism of the IRS-1 gene should not be viewed as major contributor to the development of PCOS or as a causative variant for insulin resistance.

OBJECTIVE: To evaluate the effects of gonadotropin-releasing hormone agonists (GnRH-a) on fertility in women with mild endometriosis who are undergoing in vitro fertilization and embryo transfer (IVF-ET) procedures. DESIGN: Prospective, randomized, controlled trial. SETTING: Three tertiary university hospitals. PATIENT(S): Four hundred infertile women with mild endometriosis, documented with laparoscopy, undergoing IVF and 200 women with tubal factor infertility. INTERVENTION(S): Administration of GnRH-a for 3 months before an IVF attempt (group A, n = 200) or IVF without GnRH-a (group B, n = 200). MAIN OUTCOME MEASURE(S): Follicular fluid (FF) levels of tumor necrosis factor α (TNF-α), interleukin-1ß (IL-1ß), IL-6, IL-8, and IL-1 receptor antagonist; fertilization rate (FR), implantation rate (IR), quality of embryos, and clinical pregnancy rate (PR). RESULT(S): Women who received GnRH-a had a statistically significantly reduced concentration of FF cytokines compared with women who did not receive this regimen. Women in group B had a reduced FR (61.7; 95% CI, 59.20-64.20) compared with the women in group A (72.7; 95% CI, 70.50-74.90) and compared with the women with tubal factor infertility (74.7; 95% CI, 72.00-77.24). The embryo quality, IR, and clinical PR showed no statistically significant improvement in the women of group A compared with group B. CONCLUSION(S): Women who received GnRH-a for 3 months had a lower concentration of FF cytokines. These women had also a higher FR than the women who did not receive GnRH-a. However, the IR, embryo quality, and clinical PR showed no statistically significant difference when comparing the two groups. CLINICALTRIALS. GOV ID: NCT01269125.

INTRODUCTION: Galectins constitute a phylogenetically conserved family of proteins with high binding affinity for glycoconjugates bearing ß-galactoside residues. Surprisingly, knowledge of the expression pattern of galectins during human epidermal morphogenesis is very limited. METHODS: Fifty-eight biopsy skin specimens obtained from human embryos and 10 biopsy specimens obtained from healthy adult volunteers were processed for immunohistochemistry using a panel of antibodies against galectins 1, 3, 7, and 9. RESULTS: Fetal human epidermis was devoid of any galectin 1 immunoreactivity, whereas clear-cut changes were found in the galectin 3 immunoreactivity of fetal epidermis with advancing gestational age. The expression pattern of galectins 7 and 9 remained constant at all stages of gestation. CONCLUSIONS: The changes in galectin 3 immunoreactivity of human fetal epidermis with advancing gestational age, which are reported here for the first time, suggest that this galectin and its ligands may be implicated in the molecular events underlying human epidermal morphogenesis. It remains to be elucidated in future investigations whether the expression pattern of galectins, particularly that of galectin 3, in the developing human epidermis reveals alterations in fetuses with inherited cutaneous disorders that may be important for prenatal diagnosis of these disorders.

Background: Human papillomavirus (HPV)-DNA testing combined with self-sampling could increase cervical cancer screening effectiveness, utilizing a sensitive screening modality and an easy sampling method with minimal pain or discomfort. Self-sampling acceptability, though, is pivotal. Materials and Methods: This study is a nested cross-sectional survey within GRECOSELF, a cross-sectional study on HPV-based screening with self-sampling, aiming at investigating self-sampling acceptability among Greek women residing in rural areas, and the factors affecting it. Women between 25 and 60 years old were recruited by midwives participating in a nationwide midwifery network. Participants, after self-sampling, filled out a questionnaire with three sections, one regarding demographic characteristics, a second with questions pertaining to the participants' cervical cancer screening history, and a third with questions regarding the self-sampling process per se. Results: The sample included 13,111 women. Most participants (67.9%), including those screened or not in the past, would prefer self-sampling if assured that the results are not inferior to standard testing. Discomfort or pain during self-sampling was absent or minimal in 97.1% and 96.5% of the cases, respectively, and 74.4% of the women felt adequately confident that they followed the instructions correctly. Women mostly preferred self-sampling at home compared with health care facilities. Pain and discomfort during the procedure, although rare, were significant factors against acceptance. Most of the women reporting a negative impression had a negative experience with conventional sampling in the past. Conclusion: Self-sampling is highly acceptable. Acceptance can be further improved with proper communication of the process and its noninferiority compared with conventional screening.

We report a case of a 40-year-old primipara Caucasian woman with Turner syndrome (TS) and Hashimoto thyroiditis who had underwent a successful IVF-ET cycle with oocyte donation and single embryo transfer. All pregnancies in women with TS are considered as high risk, with cardiovascular complications being the most dangerous. Our case represents a typical case of fetal growth restriction with gradual slowing down of fetal growth after 28 weeks. At 37 + 3 gestational weeks, a healthy male newborn weighing 2240 g, with artery pH of 7.32 was delivered by cesarean section. The neonate was small for gestational age. Women with TS who become pregnant need close surveillance from a multidisciplinary team of cardiologists, obstetricians and endocrinologists. The primary goal is to prevent maternal complications and to improve perinatal outcome. In doing so, a thorough evaluation of fetal growth and uteroplacental and fetal circulation should by no means be omitted, after 26-28 weeks of gestation. The examinations should be at monthly or even shorter intervals to find early signs of growth restriction and act accordingly.

OBJECTIVE: To investigate the plasma viscosity in young women with polycystic ovary syndrome (PCOS). DESIGN: Patients with PCOS and healthy controls were assessed for plasma viscosity. The acquired data were tested for association with hyperandrogenemia, obesity and insulin resistance (IR) in patients with PCOS. Plasma viscosity was determined by a viscometer Type 53610/I SCHOTT-Instruments, Mainz at 37 degrees C. PATIENTS: The study included 96 young women with PCOS and 72 healthy controls. Main outcome measures. Plasma viscosity and IR. RESULTS: Plasma viscosity was 1.243 +/- 0.67 mm(2)/s in the control group and 1.252 +/- 0.82 in women with PCOS (p = 0.416). Using multiple regression analysis, total protein (B = 0.348, p = 0.005), area under curve for insulin (B = 0.320, p = 0.011) and BMI (B = 0.315, p = 0.013) were proven to be significantly correlated to plasma viscosity. Plasma viscosity was significantly increased in women with PCOS with IR compared to matched for age and BMI PCOS women without IR (1.300 +/- 0.055 vs. 1.231 +/- 0.049 mm(2)/s) (p = 0.004). CONCLUSION: Young women with PCOS presented a plasma viscosity that was increased by obesity and IR. Therefore, clinical management of young overweight women with PCOS with IR should always include a serious reduction in body weight and the use of oral contraceptive treatment with cautious.

Self-sampling for human papillomavirus (HPV) testing is an alternative to physician sampling particularly for cervical cancer screening nonattenders. The GRECOSELF study is a nationwide observational cross-sectional study aiming to suggest a way to implement HPV-DNA testing in conjunction with self-sampling for cervical cancer screening in Greece, utilizing a midwifery network. Women residing in remote areas of Greece were approached by midwives, of a nationwide network, and were provided with a self-collection kit (dry swab) for cervicovaginal sampling and asked to answer a questionnaire about their cervical cancer screening history. Each sample was tested for high-risk (hr) HPV with the Cobas HPV test. HrHPV-Positive women were referred to undergo colposcopy and, if needed, treatment according to colposcopy/biopsy results. Between May 2016 and November 2018, 13,111 women were recruited. Of these, 12,787 women gave valid answers in the study questionnaire and had valid HPV-DNA results; hrHPV prevalence was 8.3%; high-grade cervical/vaginal disease or cancer prevalence was 0.6%. HrHPV positivity rate decreased with age from 20.7% for women aged 25-29 years to 5.1% for women aged 50-60 years. Positive predictive value for hrHPV testing and for HPV16/18 genotyping ranged from 5.0% to 11.6% and from 11.8% to 27.0%, respectively, in different age groups. Compliance to colposcopy referral rate ranged from 68.6% (for women 25-29) to 76.3% (for women 40-49). For women residing in remote areas of Greece, the detection of hrHPV DNA with the Cobas HPV test, on self-collected cervicovaginal samples using dry cotton swabs, which are provided by visiting midwives, is a promising method for cervical cancer secondary prevention.
