RESUMO
This study aimed to analyze the human papillomavirus (HPV) genotype distribution in a large cohort of high-grade vaginal intraepithelial neoplasia (VaIN) (vaginal HSIL, VaIN2/3) patients from two Italian referral centers. We included all patients with histologically confirmed VaIN2/3 from the Department of Surgical Sciences, Sant'Anna Hospital, University of Torino, Torino, Italy, and Ospedale Maggiore della Carità, Novara, Italy, between 2003 and 2022. After the histological evaluation of formalin-fixed paraffin-embedded samples, we performed HPV genotyping with VisionArray HPV Chip 1.0. We detected HPV DNA in 94.4% of VaIN2/3 (168/178), with HPV 16 as the most prevalent genotype, accounting for 51.8% of all infections, 41.2% of VaIN2 and 77.6% of VaIN3 cases. Other frequent genotypes were HPV 58 (8.3%, 10.9% of VaIN2 and 2.0% of VaIN3), HPV 73 (5.4%, 5.0% of VaIN2 and 6.1% of VaIN3), and HPV 31 (5.4%, 6.7% of VaIN2 and 2.0% of VaIN3). 73.2% of VaIN2/3 had a single HPV genotype infection and 26.8% a multiple infection (20.8% a double infection, 4.8% a triple infection, and 1.2% a quadruple infection). Single infection was more frequently present in VaIN3 than VaIN2 (81.6% vs. 69.8%). 69.1% of single infections and 73.3% of multiple infections had one or more genotypes covered by nine-valent HPV vaccine. HPV vaccination is expected to have a large impact on reducing the incidence of vaginal intraepithelial neoplasia.

Several risk factors are associated with fetal asphyxia. The main aim of this retrospective, analytical, case-control study was to determine whether assisted reproductive technologies (ART) could be considered one of these factors. In total, 162 cases of fetal asphyxia were compared to 361 controls where this event did not occur. We included 32 ART pregnancies, of which 12 were obtained through egg donations. Overall, 75% (24) of ART pregnancies experienced fetal asphyxia, suggesting ART increases the risk of fetal asphyxia by about 7 times. This finding is consistent with the literature. The pathogenesis of fetal asphyxia in ART pregnancies is currently unknown. Accordingly, this topic should be further investigated.
RESUMO
Pregnancy at advanced maternal age (AMA) is a condition of potential risk for the development of maternal-fetal complications with possible repercussions even in the long term. Here, we analyzed the changes in plasma redox balance and the effects of plasma on human umbilical cord mesenchymal cells (hUMSCs) in AMA pregnant women (patients) at various timings of pregnancy. One hundred patients and twenty pregnant women younger than 40 years (controls) were recruited and evaluated at various timings during pregnancy until after delivery. Plasma samples were used to measure the thiobarbituric acid reactive substances (TBARS), glutathione and nitric oxide (NO). In addition, plasma was used to stimulate the hUMSCs, which were tested for cell viability, reactive oxygen species (ROS) and NO release. The obtained results showed that, throughout pregnancy until after delivery in patients, the levels of plasma glutathione and NO were lower than those of controls, while those of TBARS were higher. Moreover, plasma of patients reduced cell viability and NO release, and increased ROS release in hUMSCs. Our results highlighted alterations in the redox balance and the presence of potentially harmful circulating factors in plasma of patients. They could have clinical relevance for the prevention of complications related to AMA pregnancy.

Background and Objective: Menopause can be associated with many clinical manifestations: vasomotor symptoms, urogenital problems, and additional psychological disturbances, such as anxiety, mood changes, and sleep alterations. The prolonged lack of hormones also increases the risk of long-term consequences. Hormone Replacement Treatment (HRT) in menopause consists of the administration of estrogen, alone or associated to progesterone, to relieve these uncomfortable disturbances and to prevent the onset of other pathologic conditions. The aim of this study is to examine the prevalence of HRT use in a sample of menopausal women and their experience with menopause and HRT. This study also investigates the knowledge of general practitioners (GPs) and gynecologists about HRT and its prescription. Materials and Methods: We conducted a cross-sectional population survey on 126 women of 50-59 years in an industrial city in the North of Italy, Vercelli (Novara), in Eastern Piedmont. We also presented a questionnaire on the topic to 54 medical doctors (GPs and gynecologists) of the same area. Results: The prevalence of HRT use in our sample was 11.9%. In total, a good percentage of the users affirmed to be satisfied with HRT. Additionally, a minority of women reported being ideally against the use of replacement hormones, were advised against using HRT by doctors, and did not use it because of the fear of side effects. We found a positive association between patient education, health care attitude, and HRT usage. A significant number of women knew about HRT from the media, and most of them were not informed by a health professional. Despite this, the interviewed doctors considered their knowledge about HRT as 'good' and would recommend HRT: only 5.6% would not prescribe it. Conclusions: Our results highlight the need for information about HRT among patients and health professionals, along with the need for more effective communication, evaluation, and suggestion of treatment.
