Urological Complications in Radical Surgery for Cervical Cancer: A Comparative Meta-Analysis before and after LACC Trial.

BACKGROUND: After the LACC trial publication in 2018, the minimally invasive approach (MIS) has severely decreased in favor of open surgery: MIS radical hysterectomy was associated with worse oncological outcomes than open surgery, but urological complications were never extensively explored in pre- versus post-LACC eras, even if they had a great impact on post-operative QoL. The purpose of this meta-analysis is to compare functional and organic urological complication rates before and after LACC trial. METHODS: An independent search of the literature was conducted 4 years before and after the LACC trial and 50 studies were included. RESULTS: The overall rate of urologic complications was higher in pre-LACC studies while no differences were found for organic urological complications. Conversely, the overall risk of dysfunctional urological complications showed a higher rate in the pre-LACC era. This is probably related to a sudden shift to open surgery, with potential lower thermal damage to the urinary tract autonomic nervous fibers. CONCLUSIONS: This meta-analysis showed that the incidence of urological complications in radical cervical cancer surgery was higher before the LACC trial, potentially due to the shift to open surgery. Nevertheless, further studies are needed to shed light on the connection between minimally invasive surgery and urological damage.

SARS-CoV-2 Infection in Pregnancy: Clues and Proof of Adverse Outcomes.

BACKGROUND: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) represents one of the most threatening viral infections in the last decade. Amongst susceptible individuals, infected pregnant women might be predisposed to severe complications. Despite the extensive interest in SARS-CoV-2 research, the clinical course of maternal infection, the vertical transmission and the neonatal outcomes have not been completely understood yet. The aim of our study was to investigate the association between SARS-CoV-2 infection, obstetric outcomes and vertical transmission. METHODS: A prospective observational study was performed, enrolling unvaccinated pregnant patients positive for SARS-CoV-2 (cases) and matched with uninfected pregnant women (controls). Maternal and neonatal nasopharyngeal swabs, maternal and cord blood, amniotic fluid and placenta tissue samples were collected; blood samples were tested for anti-S and anti-N antibodies, and histologic examination of placental tissues was performed. RESULTS: The cases showed a significant association with the development of some obstetric complications, such as intrauterine growth restriction and pregnancy-associated hypothyroidism and diabetes, as compared to controls; their newborns were more likely to have a low birth weight and an arterial umbilical pH less than 7. The viral genome was detected in maternal and cord blood and placental samples in six cases. CONCLUSIONS: Pregnant women positive for SARS-CoV-2 infection are more likely to develop severe obstetric outcomes; their newborns could have a low birth weight and arterial pH. Vertical transmission seems a rare event, and further investigation is strongly needed.

Attitudes towards menstruation: what women want? An Italian National Survey.

OBJECTIVE: Many women experience negative feelings during menstrual bleeding. Aim of the study was to evaluate the attitudes of Italian women towards menstrual bleeding, their desire to reduce its frequency and knowledge of the existence of methods capable of achieving such an objective. METHODS: An internet-based anonymous questionnaire has been sent to women willing to fill it in through different social media (Instagram, WhatsApp, Facebook, Twitter). The survey evaluated, objective parameters such as number of pads, use of painkillers, duration of period and pain intensity. Judgement towards period and knowledge about methods to reduce frequency and amount of menstrual flow were analysed. RESULT: 1072 Women aged 18 - 40 years, answered the survey. The level of education of responders was high, with 61.7% having a university degree. 27.5% of respondents viewed positively the occurrence of a menstrual period. Ideal frequency of menstrual cycles was considered 3 months and the perfect duration was considered to be 3 days. Half of the respondents ignored the existence of methods to suppress menstruation or reduce its frequency. 52% of participants stated that they would not use a contraceptive method because they considered it not 'natural'. CONCLUSIONS: In our sample, in spite of the discomfort reported by half of the women interviewed, menstruation was considered positively by one fourth as because confirm their fertility. The majority of women did consider bleeding every month a healthy, but they preferred a three-monthly frequency. Knowledge of contraceptive methods capable of reducing the frequency of menstrual bleeding was scarce.

In-Silico Functional Metabolic Pathways Associated to Chlamydia trachomatis Genital Infection.

The advent of high-throughput technologies, such as 16s rDNA sequencing, has significantly contributed to expanding our knowledge of the microbiota composition of the genital tract during infections such as Chlamydia trachomatis. The growing body of metagenomic data can be further exploited to provide a functional characterization of microbial communities via several powerful computational approaches. Therefore, in this study, we investigated the predicted metabolic pathways of the cervicovaginal microbiota associated with C. trachomatis genital infection in relation to the different Community State Types (CSTs), via PICRUSt2 analysis. Our results showed a more rich and diverse mix of predicted metabolic pathways in women with a CST-IV microbiota as compared to all the other CSTs, independently from infection status. C. trachomatis genital infection further modified the metabolic profiles in women with a CST-IV microbiota and was characterized by increased prevalence of the pathways for the biosynthesis of precursor metabolites and energy, biogenic amino-acids, nucleotides, and tetrahydrofolate. Overall, predicted metabolic pathways might represent the starting point for more precisely designed future metabolomic studies, aiming to investigate the actual metabolic pathways characterizing C. trachomatis genital infection in the cervicovaginal microenvironment.

SARS-CoV-2 vertical transmission in a twin-pregnant woman: a case report.

SARS-CoV-2 has affected millions of people around the world in recent years. Among susceptible patients, pregnant women seem to be prone to serious complications. The possibility of SARS-CoV-2 vertical transmission represents one of the most debated topics in the literature, providing inconclusive results. We present a case of a confirmed vertical transmission in a monochorial diamniotic twin pregnancy complicated by a selective intrauterine growth restriction and gestational diabetes mellitus. The analysis of different biological specimens identifies the presence of the SARS-CoV-2 genome in the umbilical cord blood of both twins, and the placental histologic examination confirmed indirect signs of viral infection, supporting the hypothesis that a transplacental infection can occur. Despite the devastating impact that SARS-CoV-2 has worldwide, neonatal infections have been infrequently reported, but they can occur under certain biologic conditions. Deep knowledge of the biological mechanisms underlying the risk of SARS-CoV-2 vertical transmission might be useful to understand the pathophysiological bases and the possible long-term implication of a mother-to-child vertical transmission.

What is the Hidden Biological Mechanism Underlying the Possible SARS-CoV-2 Vertical Transmission? A Mini Review.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS- CoV-2) represents an emerging infection that is spreading around the world. Among susceptible patients, pregnant women are more likely to develop serious complications and negative obstetric outcomes. Vertical transmission constitutes a debating issue which has not been completely understood. This review aims at describing the currently available evidence on SARS-CoV2 vertical transmission. We carried out a computerized literature search in the Cochrane Library, PubMed, Scopus and Web of Science, selecting the most relevant studies on vertical transmission from the outbreak onset until February 2022. The analysis of the available literature identifies the presence of SARS-CoV2 genome in different biological specimens, confirming the hypothesis that a transplacental infection can occur. In spite of the high number of infected people around the world, mother-to-child infections have been infrequently reported but it can be observed under certain biologic conditions. A deep knowledge of the underlying mechanisms of SARS-CoV2 vertical transmission is of paramount importance for planning an adequate management for the affected mothers and newborns.

Does Lung Ultrasound Have a Role in the Clinical Management of Pregnant Women with SARS COV2 Infection?

Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) infection is a major health threat. Pregnancy can lead to an increased susceptibility to viral infections. Although chest computed tomography (CT) represents the gold standard for the diagnosis of SARS-CoV-2 pneumonia, lung ultrasound (LUS) could be a valid alternative in pregnancy. The objectives of this prospective study were to assess the role of LUS in the diagnosis of lung involvement and in helping the physicians in the management of affected patients. Thirty pregnant women with SARS-CoV-2 infection were admitted at the obstetrical ward of our Hospital. Mean age was 31.2 years, mean gestational age 33.8 weeks. Several LUS were performed during hospitalization. The management of the patients was decided according to the LUS score and the clinical conditions. Mean gestational age at delivery was at 37.7 weeks, preterm birth was induced in 20% of cases for a worsening of the clinical conditions. No neonatal complications occurred. In 9 cases with a high LUS score, a chest CT was performed after delivery. CT confirmed the results of LUS, showing a significant positive correlation between the two techniques. LUS seems a safe alternative to CT in pregnancy and may help in the management of these patients.
