Prevalence of HPV Genotypes in South Europe: Comparisons between an Italian and a Turkish Unvaccinated Population

Oncofertility and Fertility Preservation for Women with Gynecological Malignancies: Where Do We Stand Today?

Oncofertility is a growing medical and research field that includes two main areas: oncology and reproductive medicine. Nowadays, the percentage of patients surviving cancer has exponentially increased, leading to the need for intervention for fertility preservation in both men and women. Specifically, gynecological malignancies in women pose an additional layer of complexity due to the reproductive organs being affected. In the present review, we report fertility preservation options with a cancer- and stage-specific focus. We explore the drawbacks and the necessity for planning fertility preservation applications during emergency statuses (i.e., the COVID-19 pandemic) and comment on the importance of repro-counseling for multifaceted patients during their oncological and reproductive journey.

Prevalence of Carcinogenic Genotypes of HPV-Infected Women in a Ten-Year Period (2014-2023) in Vojvodina, Serbia

Background and Objectives: Human papillomavirus (HPV) infection and its etiological role in the development of cervical cancer are well established. The cervical cancer mortality rate in Serbia is one of the highest among European countries, and this cancer is the second-leading cause of death in Serbian women aged from 15 to 44. Materials and Methods: This retrospective study was conducted at the Institute of Public Health of Vojvodina. A total of 10,062 cervical specimens from Serbian women were collected and HPV tested in ten years. The study patients were divided into five age groups. HPV genotype testing was performed using a commercial kit to detect 14 high-risk (HR) HPV genotypes. Additionally, cervix cytology data have been available for patients tested in 2022 and 2023. Results: An overall positive rate was found in 43.3% of patients (4356/10,062). A single HPV infection (62.1%) was the main infection pattern. The most frequent HR HPV genotypes were HPV 16, 31, 52, 56, 39, and 51, comprising 62.3% of the detected genotypes, including multiple infections. A significant difference was noted in the HPV prevalence across the different age groups, with a bimodal distribution of HPV infection. The highest prevalence was recorded in the age group ≤ 30 and those after 61 years. Women diagnosed with high-grade squamous intraepithelial lesions (HSIL) were significantly older compared to others. HR HPV is the most prevalent in patients with HSIL cytological findings (76.5%). The most common type, according to age-specific distribution and cytological findings, was HR HPV 16. Conclusions: This study provides comprehensive data on HR HPV distribution among Serbian women, which can serve as a basis for subsequent monitoring of genotypic distribution. It is particularly significant considering they are missing in the updated ICO/IARC Report for Serbia, and the cervical cancer mortality rate in Serbia is one of the highest among European countries.

E6/E7 mRNA Expression of the Most Prevalent High-Risk HPV Genotypes in Cervical Samples from Serbian Women

Cervical cancer caused by persistent infection with HR HPV genotypes is the second leading cause of death in women aged 15 to 44 in Serbia. The expression of the E6 and E7 HPV oncogenes is considered as a promising biomarker in diagnosing high-grade squamous intraepithelial lesions (HSIL). This study aimed to evaluate HPV mRNA and DNA tests, compare the results according to the severity of the lesions, and assess the predictive potential for the diagnosis of HSIL. Cervical specimens were obtained at the Department of Gynecology, Community Health Centre Novi Sad, Serbia, and the Oncology Institute of Vojvodina, Serbia, during 2017-2021. The 365 samples were collected using the ThinPrep Pap test. The cytology slides were evaluated according to the Bethesda 2014 System. Using a real-time PCR test, HPV DNA was detected and genotyped, while the RT-PCR proved the presence of E6 and E7 mRNA. The most common genotypes in Serbian women are HPV 16, 31, 33, and 51. Oncogenic activity was demonstrated in 67% of HPV-positive women. A comparison of the HPV DNA and mRNA tests to assess the progression of cervical intraepithelial lesions indicated that higher specificity (89.1%) and positive predictive value (69.8-78.7%) were expressed by the E6/E7 mRNA test, while higher sensitivity was recorded when using the HPV DNA test (67.6-88%). The results determine the higher probability of detecting HPV infection by 7% provided by the mRNA test. The detected E6/E7 mRNA HR HPVs have a predictive potential in assessing the diagnosis of HSIL. The oncogenic activity of HPV 16 and age were the risk factors with the strongest predictive values for the development of HSIL.

Vertical transmission of Human papillomavirus: experience from a center of southern Italy

BACKGROUND

Human papillomavirus (HPV) represents a group of DNA viruses, sexually transmitted, and widely accepted as a cause of invasive squamous cell carcinomas. The virus prevalence is critical worldwide. However, the possibility of perinatal transmission during pregnancy is not well understood as well as the risks for the newborn.

METHODS

Our study analyzed pregnant women referred to the obstetric outpatient room of the Department of Gynecology and Obstetrics of Sant'Anna and San Sebastiano University Hospital in Caserta, Italy. Cervicovaginal samples were achieved from patients during the first trimester and tested for HPV. The specimen was repeated during the third trimester for HPV-positive patients. After the birth, we took a placenta sample and an eye, pharyngeal, mouth, and genital samples in children from HPV positive mothers, at 36-48 hours after birth and three and six months.

RESULTS

We found out a high prevalence of HPV infections in the recruited patients: 71 participants were positive at the HPV test in the first trimester (45%), and 17 (14%) showed a positivity in the placental samples. However, there was a low prevalence of viral infection in newborns, and six newborns were positive for HPV at birth (9%).

CONCLUSIONS

HPV vertical transmission represents a critical obstetric topic, and the transplacental passage of the virus represents a possible cause. However, further studies are necessary to deepen the pathological mechanism and assess the risks for the newborn.

Sexual and reproductive health service utilization of young girls in rural Ethiopia: What are the roles of health extension workers? Community-based cross-sectional study

OBJECTIVE

Little is known about the extent to which Health Extension Programme (HEP) has played its role to increase service uptake among young girls. This study aims to estimate the status of young girls' sexual and reproductive health (SRH) services utilisation in rural Ethiopia and to examine the role of health extension workers (HEWs) in this regard.

DESIGN

A cross-sectional study.

SETTING

A community-based study among all nine regions of Ethiopia.

PARTICIPANTS

Nine hundred and two young girls aged 15-24 years were included in this study.

METHOD

We used data from the national HEP assessment, collected from March to May 2019. Multilevel binary logistic regression was used to investigate the association between exposure to HEP and SRH services utilisation of young girls and we reported an adjusted OR with a corresponding 95% CI as measure of the degree of associations.

RESULT

Only 19.18% (95% CI 16.74% to 21.89%) of young girls used SRH services with significant regional variability (intraclass correlation coefficien=17.16%; 95% CI 6.30% to 39.99%). Exposure to HEP (adjusted OR, aOR 3.13, 95% CI 2.03 to 4.85), knowing about the availability of HEP services (aOR 3.06, 95% CI 1.75 to 5.33) and having good trust in HEWs (aOR 1.82, 95% CI 1.07 to 3.10) and other sociodemographic factors were significantly associated with increased SRH services utilisation.

OUTCOME

SRH service utilisation.

CONCLUSION

Although the overall SRH service utilization of young girls in rural Ethiopia was very low, HEWs have a great contribution to improving service utilization of young girls through strong health education provided during home visits, school visits and at health posts. More investment along this line has the potential to improve service uptake among young girls. Encouraging HEWs to build trust among this segment of the population and creating awareness of SRH-related services is crucial to improv service uptake.

Microbiota and HPV: the role of viral infection on vaginal microbiota

The World Health Organization (WHO) estimates that the prevalence of human papillomaviruses (HPV) infection is between 9% and 13% of the world population and only in the United States, more than 6.2 million are positive every year. There are more than 100 types of HPV, among them, two serotypes (16 and 18) are related to 70% of cervical cancers and precancerous cervical lesions. The vaginal microbiota could play a considerable role in HPV infection and the genesis of cervical tumors caused by HPV. Moreover, bacteria are strongly associated with vaginal inflammation and oncogenic mutations in human cells. We aim to investigate whether HPV infection could influence the bacterial microbiota composition in the uterine cervix. A total of 31 women were enrolled in this study. The vaginal swabs were collected; the HPV‐DNA was extracted with QIAamp DNA Microbiome. The V3–V4–V6 region of the 16S rDNA gene was amplified by polymerase chain reaction (PCR) followed by sequencing with MiSeq Illumina. The main phylum identified in the vaginal microbiota were Firmicutes, Bacteroidetes, Proteobacteria, and Actinobacteria. The phylum of Actinobacteria, Proteobacteria, and Bacteroides was more represented in HPV‐positive patients. Lactobacilli represented the dominant genus, with a high percentage of Lactobacilli iners, Lactobacilli jensenii, and Lactobacilli crispatus as species. Gardnerella vaginalis, Enterococcus spp., Staphylococcus spp., Proteus spp., and Atopobium were the most represented in HPV‐positive patients. An altered vaginal microbiota might play a functional role in HPV cervical infection, progression, and clearance. The relationship between infection and microbiota could spur the development of new probiotics. However, further studies are needed to clarify the role of the vaginal microbiota in HPV infection.

Was there any change in tobacco smoking among adults in Bangladesh during 2009-2017? Insights from two nationally representative cross-sectional surveys

OBJECTIVE

This study assessed the changes in prevalence and associated factors of tobacco smoking among Bangladeshi adults over time.

DESIGN

Nationally representative cross-sectional surveys.

SETTING

Two most recent Global Adults Tobacco Survey (GATS) data from Bangladesh, carried out in 2009 and 2017.

PARTICIPANTS

Adult population aged 15 and above (n=9629 in 2009; n=12 783 in 2017).

OUTCOME MEASURES

Current use of tobacco smoke, including cigarettes, bidi, hukkah, cigars or pipes, which was dichotomised ('yes'/'no').

METHODS

We analysed data from two recent rounds of GATS (2009 and 2017). Multivariate logistic regression analysis was used.

RESULTS

The overall prevalence of tobacco smoking among Bangladeshi adults was noted (23.00%, 95% CI 22.98 to 23.00 in 2009; 16.44%, 95% CI 16.43 to 16.45 in 2017). Being male (adjusted OR (AOR)=59.72, CI 40.56 to 87.93 for 2009; AOR=71.17, CI 41.08 to 123.32 for 2017), age between 25 and 64 years (all AORs >2 and p<0.05), smoking permissible at home (AOR=7.08, CI 5.88 to 8.52 for 2009; AOR=5.90, CI 5.34 to 6.95 for 2017), and watching tobacco smoking product use in movie/drama scenes (AOR=1.26, CI 1.11 to 1.44 for 2009; AOR=1.34, CI 1.17 to 1.54 for 2017) were found to be significantly associated with increased tobacco smoking among adults both in 2009 and in 2017. However, being offered free tobacco sample products (AOR=0.66, CI 0.57 to 0.77 for 2009; AOR=0.87, CI 0.76 to 0.99 for 2017) and having primary, secondary or higher education (all AORs <1 and p<0.05) as well as being a student (AOR=0.16, CI 0.09 to 0.29 for 2009; AOR=0.32, CI 0.19 to 0.53) were associated with lower odds of tobacco smoking in both surveys.

CONCLUSIONS

Although the prevalence of tobacco smoking has declined over the period, it is still high among those who were relatively older, men, less educated and exposed to a movie/drama where tobacco smoking is promoted. Therefore, appropriate interventions are required to stop tobacco smoking among the Bangladeshi population.

Fertility preservation in women affected by gynaecological cancer: the importance of an integrated gynaecological and psychological approach

Gynaecological cancer treatment significantly affects the fertility of women in reproductive age. Surgery, chemotherapy and radiotherapy are the mainstays of ovarian, cervical and endometrial cancers and anatomically or functionally impact the uterus and ovaries. Moreover, the sexual function and psychological wellbeing of patients are highly weakened after a cancer diagnosis: depression, anxiety and impairment of quality of life represent a relevant concern for patient care. The potential loss of fertility could be more distressing than cancer itself. For this reason, it is of paramount importance to try to preserve fertility in women affected by gynaecological cancers. Recently, tailored fertility preservation therapies have been developed to meet the childbearing demand from more than half of women between 18 and 40 years with a diagnosis of cancer. Currently, fertility preservation techniques play a significant role in improving the quality of life of women with gynaecological cancer. In this scenario, we propose a narrative overview of the recent literature about the importance of a multidisciplinary approach in the management of fertility preservation in the case of gynaecological cancers.

Flow Cytometry Characterization of Pluripotent Transmembrane Glycoproteins on Resident Cervix Uteri Cells in Patients Screened for Cervical Cancer

The aim of this study was to characterize both by flow cytometry analysis and immunohistochemistry cervix uteri cells of nulliparous women screened for cervical intraepithelial neoplasia (CIN) in comparison to a group without CIN by using mesenchymal stem cell-like and hematopoietic lineage markers. A significant expression for CD29, CD38, HLA-I, and HLA-II was correlated positively to the CIN degree and it was more relevant in patients positive for human papilloma virus (HPV). Thus, identification and detailed characterization of pluripotent resident in uteri cells could be a promising therapeutic target.
