Abstract
Current estimates of the HPV infection rate in China vary by geographic region (9.6-23.6%), with two age peaks in prevalence in women ≤20-25 years of age and 50-60 years of age. HPV-16, 52 and 58 are the most commonly-detected HPV genotypes in the Chinese population. In China, five HPV vaccines are licensed and several others are undergoing clinical trials. Multiple RCTs have shown the efficacy and safety of the bvHPV (Cervarix), Escherichia coli-produced bvHPV (Cecolin), Pichia pastoris-produced bvHPV (Walrinvax), qvHPV (Gardasil) and 9vHPV (Gardasil-9) vaccines in Chinese populations, including two studies showing long-term efficacy (≥8 years) for the bvHPV and qvHPV vaccines. Real-world data from China are scarce. Although modeling studies in China show HPV vaccination is cost-effective, uptake and population coverage are relatively low. Various policies have been implemented to raise awareness and increase vaccine coverage, with the long-term aim of eliminating cervical cancer in China.

Human papillomavirus vaccination coverage among young women in the three sub-Saharan African countries using Demographic and Health Surveys data. Hum Vaccin Immunother 2024; 20:2370111. [PMID: 38946555 PMCID: PMC11218800 DOI: 10.1080/21645515.2024.2370111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Accepted: 06/17/2024] [Indexed: 07/02/2024] Open
Abstract
Cervical cancer is the fourth most common cancer, with 99% of cases linked to human papillomavirus (HPV) infection. It reflects global inequity as its burden is highest in low- and middle-income countries. The aim of this study was to determine the HPV vaccination coverage and its determinant factors among young women in the three sub-Saharan African countries. Data from the Demographic and Health Surveys among three sub-Saharan African countries were used for analysis. A total of 4,952 women were included in the study. Stata 14 was used to analyze the data. The determinants of the outcome variable were identified using a multilevel mixed-effects logistic regression model. Factors with p-values < 0.05 at 95% confidence interval were declared statistically significant. About 7.5% young women were vaccinated for HPV vaccine against cervical cancer in the current study. Younger age, use of internet, rich economic class, and individual-level media exposure were found to be favorable conditions, whereas being employed was negatively associated with HPV vaccination. Only few segments of young women in these three countries got HPV vaccination. The authors recommend that increasing internet use, media exposure, and economic level of young women will increase the HPV vaccination rates. Furthermore, creating awareness among employed women will also increase the possibility of HPV vaccination.

Abstract
Periodontitis is a severe gum infection that begins as gingivitis and can lead to gum recession, bone loss, and tooth loss if left untreated. It is primarily caused by bacterial infection, which triggers inflammation and the formation of periodontal pockets. Notably, periodontitis is associated with systemic health issues and has been linked to heart disease, diabetes, respiratory diseases, adverse pregnancy outcomes, and cancers. Accordingly, the presence of chronic inflammation and immune system dysregulation in individuals with periodontitis significantly contributes to the initiation and progression of various cancers, particularly oral cancers. These processes promote genetic mutations, impair DNA repair mechanisms, and create a tumor-supportive environment. Moreover, the bacteria associated with periodontitis produce harmful byproducts and toxins that directly damage the DNA within oral cells, exacerbating cancer development. In addition, chronic inflammation not only stimulates cell proliferation but also inhibits apoptosis, causes DNA damage, and triggers the release of pro-inflammatory cytokines. Collectively, these factors play a crucial role in the progression of cancer in individuals affected by periodontitis. Further, specific viral and bacterial agents, such as hepatitis B and C viruses, human papillomavirus (HPV), Helicobacter pylori (H. pylori), and Porphyromonas gingivalis, contribute to cancer development through distinct mechanisms. Bacterial infections have systemic implications for cancer development, while viral infections provoke immune and inflammatory responses that can lead to genetic mutations. This review will elucidate the link between periodontitis and cancers, particularly oral cancers, exploring their underlying mechanisms to provide insights for future research and treatment advancements.

Abstract
BACKGROUND HPV is considered the most common sexually transmitted infection. It is responsible of 70% of cervical cancers worldwide. HIV infection is associated with increased rates of HPV infection. Women Living With HIV (WLWH) are 6 times at greater risk of developing cervical cancer. The current study aimed to estimate prevalence and identify genotypes of HPV infection among WLWH in Egypt compared to women with negative HIV status and determine associated risk factors. METHODS The study conducted among 251 WLWH and 268 women with negative HIV status enrolled from gynecological clinics in primary health care centers from nine Egyptian governorates. Data was collected from participants using a structured interview questionnaire and cervical samples were collected for HPV DNA detection and genotyping. RESULTS The overall prevalence of HPV infection was 13.5%, 3.4% among women with HIV negative status and 24.4% among WLWH. HR-HPVs other than genotype 16 and 18 were isolated from 71% of infected women. Woman's age, age at first marriage, number of lifetime marriages and drug addiction are significant predictors for HPV infection (odds 0.96, 0.91, 2.06, 2.01 respectively). CONCLUSION HPV infection is more prevalent among WLWH. Infection with HR-HPV other than genotype 16 and 18 was the most prevalent among infected women in both groups. Young age, early life sexual activity, having more than one sexual partner during the life time, and drug addiction are independent predictors for HPV infection. Having a husband who has had other sexual partners is significantly associated with infection.

Abstract
Copper, an indispensable micronutrient, is implicated in numerous vital biological processes and is essential for all physiological activities. Recently, the discovery of a novel type of copper-dependent cell death, known as cuproptosis, has shed light on its role in cancer development. Extensive research is currently underway to unravel the mechanisms underlying cuproptosis and its correlation with various cancer types. In this review, we summarize the findings regarding the roles and mechanisms of cuproptosis in various cancer types, including colorectal cancer, lung cancer, gastric cancer, breast cancer, liver cancer and cutaneous melanoma. Furthermore, the effects of copper-related agents such as copper chelators and copper ionophores on cell proliferation, apoptosis, angiogenesis, tumor immunity, and chemotherapy resistance have been explored in cancer preclinical and clinical trials. These insights provide promising avenues for the development of prospective anticancer drugs aimed at inducing cuproptosis.

Abstract
Human papillomavirus can be contracted by sexually active women. However, only a small proportion of these infections persist and have the potential to progress into cervical cancers, indicating a significant involvement of the immune system in cervical cancer development. Despite this, our understanding of the precise contributions of genes from different immune cell types in cervical cancers remains limited. Therefore, the primary objective of our study was to investigate the potential causal relationships between specific immune cell genes and the development of cervical cancers. By accessing expression quantitative trait loci datasets of 14 distinct immune cell types and genome wide association study of cervical cancers, we employed the summary data-based Mendelian randomization (SMR) along with multi-single nucleotide polymorphism (SNP)-based SMR to identify significant genes associated with cervical cancers. Colocalization analysis was further conducted to explore the shared genetic causality. A total of 10 genes across 11 immune cell types (26 significant gene-trait associations) were found to be associated with cervical cancers after false discovery rate correction. Notably, the ORMDL3, BRK1 and HMGN1 gene expression levels showed significant association with cervical cancer in specific immune cell types, respectively. These associations were supported by strong evidence of colocalization analyses. Our study has identified several genes in different immune cells that were associated with cervical cancer. However, further research is necessary to confirm these findings and provide more comprehensive insights into the association between these gene expressions and cervical cancer risk.

Abstract
E6 and E7 human papillomavirus (HPV) oncoproteins play a significant role in the malignant transformation of infected cervical cancer cells via suppression of tumour suppressor pathways by targeting p53 and pRb, respectively. This study aimed to investigate the anticancer effects of Oroxylum indicum (OI) leaves' methanol extract on SiHa cervical cancer cells. Expression of apoptosis-related proteins (Bcl-2, caspase (cas)-3, and cas-9), viral oncoproteins (E6 and E7), and tumour suppressor proteins (p53 and pRb) were evaluated using western blot analysis before and after E6/E7 small interfering RNAs (siRNAs) transfection. In addition, the E6/E7 mRNA expression levels were assessed with real-time (RT)-PCR. The present study showed that the OI extract effectively hindered the proliferation of SiHa cells and instigated increments of cas-3 and cas-9 expressions but decreased the Bcl-2 expressions. The OI extract inhibited E6/E7 viral oncoproteins, leading to upregulation of p53 and pRb tumour suppressor genes in SiHa cells. Additionally, combinatorial treatment of OI extract and gossypin flavonoid induced restorations of p53 and pRb. Treatment with OI extract in siRNA-transfected cells also further suppressed E6/E7 expression levels and further upregulations of p53 and pRb proteins. In conclusion, OI extract treatment on siRNAs-transfected SiHa cells can additively and effectively block E6- and E7-dependent p53 and pRb degradations. All these data suggest that OI could be explored for its chemotherapeutic potential in cervical cancer cells with HPV-integrated genomes.

Abstract
Background Obesity and gastric cancer (GC) are prevalent diseases worldwide. In particular, the number of patients with obesity is increasing annually, while the incidence and mortality rates of GC are ranked high. Consequently, these conditions seriously affect the quality of life of individuals. While evidence suggests a strong association between these two conditions, the underlying mechanisms of this comorbidity remain unclear. Methods We obtained the gene expression profiles of GSE94752 and GSE54129 from the Gene Expression Omnibus database. To investigate the associated biological processes, pathway enrichment analyses were conducted using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes for the shared differentially expressed genes in obesity and GC. A protein-protein interaction (PPI) network was subsequently established based on the Search Tool for the Retrieval of Interacting Genes (STRING) database, followed by the screening of the core modules and central genes in this network using Cytoscape plug-in MCODE. Furthermore, we scrutinized the co-expression network and the interplay network of transcription factors (TFs), miRNAs, and mRNAs linked to these central genes. Finally, we conducted further analyses using different datasets to validate the significance of the hub genes. Results A total of 246 shared differentially expressed genes (209 upregulated and 37 downregulated) were selected for ensuing analyses. Functional analysis emphasized the pivotal role of inflammation and immune-associated pathways in these two diseases. Using the Cytoscape plug-in CytoHubba, nine hub genes were identified, namely, CXCR4, CXCL8, CXCL10, IL6, TNF, CCL4, CXCL2, CD4, and CCL2. IL6 and CCL4 were confirmed as the final hub genes through validation using different datasets. The TF-miRNA-mRNA regulatory network showed that the TFs primarily associated with the hub genes included RELA and NFKB1, while the predominantly associated miRNAs included has-miR-195-5p and has-miR-106a-5p. Conclusion Using bioinformatics methods, we identified two hub genes from the Gene Expression Omnibus datasets for obesity and GC. In addition, we constructed a network of hub genes, TFs, and miRNAs, and identified the major related TFs and miRNAs. These factors may be involved in the common molecular mechanisms of obesity and GC.

Abstract
Background Women living with HIV/AIDS (WLHA) have an increased prevalence of high-risk HPV infection (HR-HPV) and cervical intraepithelial neoplasia (CIN) and a greater risk of cervical cancer despite access to a new generation of antiretroviral therapy. The aim of this study is to evaluate the concentrations of different cytokines involved in the local immune response in WLHA, which is fundamental for understanding the pathogenesis of HPV-related cancer in this population. Methods IL-1β, IL-2, IL-4, IL-6, IL-10, IFN-γ, TNF-α, IP-10, GM-CSF, and MIP-1α were investigated in the cervicovaginal lavage (CVL) of 106 WLHA attending at Hospital Universitario Professor Edgard Santos in Salvador, Bahia, Brazil, during the period December 2019 to April 2023 by Luminex®. All participants were also tested for Chlamydia trachomatis and Neisseria gonorrhoeae and underwent colposcopy, Pap smear, and Nugent score. HIV plasma viral load (VL) and CD4 cell count were performed for all WLHA. Results In this study, 22.6% (24/106) of WLHA were infected with HR-HPV. A higher proportion of patients with HR-HPV (66.7%) had detectable levels of IL-10 than those negative ones (40.2%, p = 0.02). More premenopausal women had either IL-6 (51.4%) or IP-10 (58.3%) than those in menopausal status (26.5% for IL-6 and 32.4% for IP-10, p = 0.013 and p = 0.011, respectively). Vaginosis was negatively associated with detection of IP-10 (24.2% vs. 61.4%, p < 0.001) and INF-γ (39.4% vs. 68.6%, p = 0.005). A positive association was detected for IL-1β (66.7 vs. 37.1%, p = 0.005) and IL-10 (63.6% vs. 37.1%, p = 0.01). VL and CD4 were not associated with the studied cytokines. Conclusion We demonstrated a positive association between IL-10 and HPV infection in CVL, suggesting the predominance of the Th2 response in HIV/HPV co-infected patients. However, further studies with longer follow-up will be needed to evaluate the association of IL-10 with HPV infection, CIN, and cervical cancer in WLHA.

Abstract
Cervical cancer (CC) is one of the leading causes of death among women worldwide. The current treatments for this cancer consist of invasive methods such as chemotherapeutic drugs, radiation, immunotherapy and surgery, which could lead to severe side effects and hinder the patient's life quality. Although metal-based therapies, including cisplatin and ruthenium-based compounds, offer promising alternatives, they lack specificity and harm healthy cells. Combining metal nanoparticles with standard approaches has demonstrated remarkable efficacy and safety in the fight against CC. Overall, this review is intended to show the latest advancements and insights into metal-based strategies, creating a promising path for more effective and safer treatments in the battle against CC.

Abstract
Background Despite the availability of effective vaccines, human papillomavirus (HPV) vaccine uptake remains low in most resource-limited settings including Nigeria. Mobile health technology (mHealth) may empower patients to control their health, reduce inequalities, and improve the uptake of HPV vaccination. Aim The "mHealth-HPVac" study will assess the effects of mHealth using short text messages on the uptake of HPV vaccination among mothers of unvaccinated girls aged 9-14 years and also determine the factors influencing the uptake of HPV vaccination among these mothers. Methods This protocol highlights a randomised controlled trial involving women aged 25-65 years who will be enrolled on attendance for routine care at the General Outpatient clinics of Lagos University Teaching Hospital, Lagos, Nigeria between July and December 2024. At baseline, n=224 women will be randomised to either a short text message or usual care (control) arm. The primary outcome is vaccination of the participant's school-age girl(s) at any time during the 6 months of follow-up. The associations between any two groups of continuous variables will be tested using the independent sample t-test (normal distribution) or the Mann-Whitney U test (skewed data) and that of two groups of categorical variables with Chi-square (X2) or Fisher's exact test where appropriate. Using the multivariable binary logistic regression model, we will examine the effects of all relevant sociodemographic and clinical variables on HPV vaccination uptake among mothers of unvaccinated but vaccine-eligible school-age girls. Statistical significance will be defined as A P<0.05. Discussion The mHealth-Cervix study will evaluate the impact of mobile technologies on HPV vaccination uptake among mothers of unvaccinated but vaccine-eligible school-age girls in Lagos, Nigeria as a way of contributing to the reduction in the wide disparities in cervical cancer incidence through primary prevention facilitated using health promotion to improve HPV vaccination uptake.

Abstract
Rapid, low-cost and high-specific diagnosis based on nucleic acid detection is pivotal in both detecting and controlling various infectious diseases, effectively curbing their spread. Moreover, the analysis of circulating DNA in whole blood has emerged as a promising noninvasive strategy for cancer diagnosis and monitoring. Although traditional nucleic acid detection methods are reliable, their time-consuming and intricate processes restrict their application in rapid field assays. Consequently, an urgent emphasis on point-of-care testing (POCT) of nucleic acids has arisen. POCT enables timely and efficient detection of specific sequences, acting as a deterrent against infection sources and potential tumor threats. To address this imperative need, it is essential to consolidate key aspects and chart future directions in POCT biosensors development. This review aims to provide an exhaustive and meticulous analysis of recent advancements in POCT devices for nucleic acid diagnosis. It will comprehensively compare these devices across crucial dimensions, encompassing their integrated structures, the synthesized nanomaterials harnessed, and the sophisticated detection principles employed. By conducting a rigorous evaluation of the current research landscape, this review will not only spotlight achievements but also identify limitations, offering valuable insights into the future trajectory of nucleic acid POCT biosensors. Through this comprehensive analysis, the review aspires to serve as an indispensable guide for fostering the development of more potent biosensors, consequently fostering precise and efficient POCT applications for nucleic acids.

Abstract
Human papillomavirus (HPV), a common cause of sexually transmitted diseases, may cause warts and lead to various types of cancers, which makes it important to understand the risk factors associated with it. HPV is the leading risk factor and plays a crucial role in the progression of cervical cancer. Viral oncoproteins E6 and E7 play a pivotal role in this process. Beyond cervical cancer, HPV-associated cancers of the mouth and throat are also increasing. HPV can also contribute to other malignancies like penile, vulvar, and vaginal cancers. Emerging evidence links HPV to these cancers. Research on the oncogenic effect of HPV is still ongoing and explorations of screening techniques, vaccination, immunotherapy and targeted therapeutics are all in progress. The present review offers valuable insight into the current understanding of the role of HPV in cancer and its potential implications for treatment and prevention in the future.

Population-based norms for the human papillomavirus-quality of life (HPV-QoL) questionnaire: A cross-sectional multicenter study. Acta Obstet Gynecol Scand 2024. [PMID: 38872262 DOI: 10.1111/aogs.14877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 04/26/2024] [Accepted: 05/04/2024] [Indexed: 06/15/2024]
Abstract
INTRODUCTION Human papillomavirus (HPV) diagnosis has a considerable emotional and psychological impact on women. To evaluate the impairment this infection leads to regarding quality of life (QoL), several scales have been suggested, such as the human-papillomavirus-quality-of-life (HPV-QoL) questionnaire. This has been validated for the Spanish population and measures the impact of HPV on health-related-quality-of-life (HR-QoL). However, normative values are yet to be developed. Thus, the objective was to describe the population-based norms of the HPV-QoL for Spanish women aged 25-65 years and to test the questionnaire's construct validity. MATERIAL AND METHODS This was a cross-sectional nationwide multicenter study. Women from outpatient clinics in Spain aged 25-65 years, with a diagnosis of past or active HPV infection were recruited. The central tendency, dispersion, and percentiles were calculated for the total score and its dimensions for each age group. Construct validity was tested by analyzing age groups and their correlations with other related scales (12-Item General Health Questionnaire [GHQ-12], Female Sexual Function Index [FSFI], and Hospital Anxiety and Depression Scale [HADS]). RESULTS A total of 1352 women were included in the study. The norms showed moderate and significant coefficients of correlation with other related scales. Significant differences between age strata groups were found according to educational level, sexual dysfunction, sexual activity, mental deterioration, and severity of anxiety and depression symptoms (p < 0.001 in all cases). The total score differed significantly between the groups (p = 0.006). Significant differences in the contagiousness, health, and sexuality dimensions (p < 0.05) were found among the groups. It was seen that HPV infection impaired women's QoL. Dimensions within all test age groups (p < 0.001 in all cases) were significantly different, with the health dimension being the highest contributor to women's QoL impairment, whereas social well-being was the main determinant of QoL. CONCLUSIONS Population-based norms for the novel HPV-QoL questionnaire showed adequate validity and could be a useful tool for assessing the impact of QoL among women with HPV in Spain.

Abstract
BACKGROUND AND OBJECTIVES The efficacy and safety of PD-L1 inhibitors in the treatment of cervical cancer is an ongoing research question. This review aims to establish a clear profile of atezolizumab, examining its impact on survival outcomes, response rates, and safety measured by serious adverse events (SAEs). MATERIALS AND METHODS A literature search was conducted using PubMed, Scopus, and Web of Science, focusing on articles published up to February 2024. The review followed the PRISMA guidelines and synthesized outcomes from four randomized trial studies involving atezolizumab administered at 1200 mg IV every three weeks, alone or in combination with chemoradiotherapy. RESULTS A total of 284 patients received atezolizumab, the majority being advanced stage cervical cancer (IVA-IVB). Median follow-up times ranged from 9 weeks to 32.9 months. It was found that combining atezolizumab with standard therapies extended median progression-free survival (PFS) from 10.4 to 13.7 months and overall survival (OS) from 22.8 to 32.1 months, according to the phase III trial. Monotherapy and initial treatment settings with atezolizumab also showed promising efficacy, with disease-free survival rates at 24 months reaching 79% compared to 52% with standard therapy alone. However, the treatment was associated with high rates of SAEs, reaching up to 79% in more intensive treatment combinations. CONCLUSIONS Atezolizumab demonstrates significant potential in improving PFS and OS in patients with cervical cancer, supporting its inclusion as a first-line treatment option. Despite the efficacy benefits, the high incidence of SAEs necessitates careful patient selection and management strategies to mitigate risks. This systematic review supports the continued evaluation of atezolizumab in broader clinical trials to refine its therapeutic profile and safety measures in the context of cervical cancer treatment.

Abstract
Background This study aimed to investigate the knowledge, attitude, and practice (KAP) of human papillomavirus (HPV) and self-sampling among adult women. Methods The cross-sectional, questionnaire-based study included adult women at Shanghai Pudong Hospital from October 14, 2022, to March 31, 2023. The questionnaire contained demographic information, knowledge, attitude and practice dimensions. Factors associated with KAP and self-sampling were identified by multivariate logistic regression. Results A total of 1843 valid questionnaires were collected. The average knowledge, attitude, and practice score was 10.09 ± 5.60, 26.76 ± 3.80, and 6.24 ± 2.20, respectively. Urban residents (estimate = 0.705, p < 0.001), suburban residents (estimate = 0.512, p < 0.001), as well as individuals with undergraduate degrees and higher (estimate = 0.535, p < 0.001), were associated with good knowledge, while individuals lacking a history of HPV infection (estimate = -0.461, p < 0.001) and married individuals (estimate = -0.185, p < 0.001) were less likely to have good knowledge. Higher knowledge scores (estimate = 0.087, p < 0.001) and individuals with undergraduate education and above (estimate = 1.570, p < 0.001) were associated with a positive attitude. Being married (estimate = 0.291, p = 0.049) was associated with good practice, whereas not engaging in sexual activity (estimate = -0.959, p < 0.001) or lacking a history of HPV infection (estimate = -0.499, p = 0.011) were associated with unfavorable practices. Minorities (OR = 2.787, p = 0.038) and individuals with multiple sexual partners (OR = 2.297 for two partners, OR = 2.767 for three or more partners, p = 0.020 and p = 0.022) were positively associated with self-sampling. However, higher knowledge (OR = 0.952, p = 0.026) and attitude scores (OR = 0.929, p = 0.015) were negatively associated with self-sampling. Conclusion Demographic and behavioral factors significantly influenced KAP scores and self-sampling behaviors regarding HPV. Urban residency, higher education levels, positive attitudes, and minority status correlated with favorable outcomes, while factors like marriage and lack of sexual activity were associated with less favorable practices.

Abstract
Cervical cancer is one of the most common gynecological malignancies, with the vast majority of which being caused by persistent infection with Human Papillomavirus (HPV) 16 and 18. The current available HPV detection methods are sensitive and genotyped but are restricted by expensive instruments and skilled personnel. The development of an easy-to-use, rapid, and cost-friendly analysis method for HPV is of great need. Herein, hollow palladium-ruthenium nanocages modified with two oligonucleotides (PdRu capture probes) were constructed for genotyping and simultaneous detection of target nucleic acids HPV16 and HPV18 by dual lateral flow assay (DLFA). PdRu capture probes were endowed with bi-functions for the first time, which could be used to output signals and hybridize target nucleic acids. Under optimized conditions, the PdRu based-DLFA with detection limits of 0.93 nM and 0.19 nM, respectively, exhibited convenient operation, and high sensitivity. Meanwhile, the DLFA achieved excellent rapid detection within 20 min, which was attributed to capture probes that can be directly bound to amplification-free target nucleic acids. Therefore, the development of PdRu-based DLFA can be utilized for rapid, sensitive, and simultaneous genotyping detection of HPV16 and HPV18, showing great application for nucleic acid detection.

Abstract
Purpose: The aim of this study is to reveal female university students' knowledge and perceptions about cervical cancer (CC) and human papillomavirus (HPV), and relationship with e-health literacy (e-HL). It also aims to determine the predictors affecting CC and HPV. Methods: A cross-sectional study was conducted with 589 female university students in Türkiye. Data were collected using a "Cervical Cancer and HPV Awareness Questionnaire" and an "E-health Literacy Scale (e-HLS)." Analysis involved Pearson correlation analysis, Independent Sample t-test, one-way analysis of variance, and Linear Regression analysis. Results: Results indicate that female students exhibited a low level of knowledge and perception about CC and HPV. Only 2.90% of students reported being vaccinated, while 39.90% had sexual experience. Higher knowledge levels were observed among married individuals, those familiar with HPV and the HPV vaccine, those who had undergone Pap smear tests, sexually active individuals, and consistent condom users. e-HL had a positive impact on knowledge and perceived threat about CC and HPV. The affecting predictors for knowledge about CC and HPV were found to be e-HLS (β = 0.911), having prior knowledge of HPV (β = 0.201), and being aware of the HPV vaccine (β = 0.172). In terms of perceived threat, the affecting predictors were e-HLS (β = 0.207), having heard of HPV (β = 0.101), and having knowledge of the HPV vaccine (β = 0.092). Conclusion: e-HL emerged as a crucial predictor positively influencing knowledge and perceptions about CC and HPV. This suggests the potential for organizing digital health campaigns to enhance awareness and understanding of CC and HPV.

Abstract
Cervical cancer is one of the most frequent cancers in women and is associated with human papillomavirus (HPV) in 70 % of cases. Cervical cancer occurs because of progression of low-differentiated cervical intraepithelial neoplasia through grade 2 and 3 lesions. Along with the protein-coding genes, long noncoding RNAs (lncRNAs) play an important role in the development of malignant cell transformation. Although human papillomavirus is widespread, there is currently no well-characterized transcriptomic signature to predict whether this tumor will develop in the presence of HPV-associated neoplastic changes in the cervical epithelium. Changes in gene activity in tumors reflect the biological diversity of cellular phenotype and physiological functions and can be an important diagnostic marker. We performed comparative transcriptome analysis using open RNA sequencing data to assess differentially expressed genes between normal tissue, neoplastic epithelium, and cervical cancer. Raw data were preprocessed using the Galaxy platform. Batch effect correction, identification of differentially expressed genes, and gene set enrichment analysis (GSEA) were performed using R programming language packages. Subcellular localization of lncRNA was analyzed using Locate-R and iLoc-LncRNA 2.0 web services. 1,572 differentially expressed genes (DEGs) were recorded in the "cancer vs. control" comparison, and 1,260 DEGs were recorded in the "cancer vs. neoplasia" comparison. Only two genes were observed to be differentially expressed in the "neoplasia vs. control" comparison. The search for common genes among the most strongly differentially expressed genes among all comparison groups resulted in the identification of an expression signature consisting of the CCL20, CDKN2A, CTCFL, piR-55219, TRH, SLC27A6 and EPHA5 genes. The transcription level of the CCL20 and CDKN2A genes becomes increased at the stage of neoplastic epithelial changes and stays so in cervical cancer. Validation on an independent microarray dataset showed that the differential expression patterns of the CDKN2A and SLC27A6 genes were conserved in the respective gene expression comparisons between groups.

Abstract
Background and Aims Human papillomavirus (HPV) infections that continue to exist are the main cause of cervical cancer (CC), two-thirds of CC occurrences worldwide are caused by HPV 16 and HPV 18, and 99.7% of CC tumors are linked to oncogenic HPV infection. To identify challenges of CC and its prevention and treatment modalities. Methods This review examined the epidemiology, predisposing factors, genetic factors, clinical assessment methods, current treatment options, and prevention approaches for CC. We had perform a narrative data synthesis rather than a pooled analysis. A thorough literature search in pertinent databases related to CC was done with the inclusion of data that were published in the English language. Results Early detection of CC is of utmost importance to detect precancerous lesions at an early stage. Therefore, all responsible agencies concerned with health should make all women aware of the benefits of CC screening and educate the general public. HPV vaccination coverage is very low in resource-limited settings. Conclusion To achieve the goal of eliminating CC as a public health problem in 2030, the World Health Organization will pay special attention to increasing HPV vaccination coverage throughout the world. To further improve HPV vaccine acceptability among parents and their children, safety-related aspects of the HPV vaccine should be further investigated through post-marketing surveillance and multicentre randomized clinical trials.

Abstract
Cancer is a disease in which abnormal cells divide uncontrollably, destroying tissues. A malignant tumor arises from cells in the cervix, the lower portion of the uterus (womb) that links the uterus to the vagina (birth canal), and is known as cervical cancer. One of the most significant global community health problems is cancer, which sees a daily increase in the number of sufferers. Therefore, it is crucial to expand our understanding of the molecular pathophysiology of cervical cancer and to suggest new therapeutic goals as well as new techniques for early detection of the illness. Since early diagnosis of pathologies can dramatically increase a patient's chance of survival, prognosis, and recurrence. This article aims to educate readers about some essential concepts surrounding cervical cancer, including the various types of cervical cancer, the stages of cancer, as well as their etiology, epidemiology, pathogenesis, management, and treatment, and its relationship with pregnancy. All of these concepts are essential for any individual studying medicine or working in the medical industry to understand. We intend to summarize the information that is currently available and the recommended courses of action for treating cervical cancer and its association with pregnancy in this review. Research priorities and controversies are also noted.

Abstract
Cervical cancer affects thousands of women globally with recurring high-risk HPV infections being at the centre of cervical pathology. Oncological treatment strategies are continually challenged by both chemoresistance and metastasis within patients. Although both work hand-in-hand, targeting their individual mechanisms could prove highly beneficial for treatment outcomes. Such targets include the metastatic-promoting stem cell marker, CD44, which is abundant in cervical cancer cells and is common to both chemoresistance and metastatic mechanisms. Seeing that many existing advanced-stage cervical cancer treatment regimes, such as platinum-based chemotherapy regimens, remain limited and are rarely curative, alternative treatment options within the field of immunology are being considered. The use of immune checkpoint inhibition therapy, which targets immune checkpoints, CTLA-4 and PD-1/PD-L1, has shown promise as an alternate standard of care for patients suffering from advanced-stage cervical cancer. Therefore, this review aims to assess whether immune checkpoint inhibition can mitigate the pathological effects of CD44-induced EMT, metastasis, and chemoresistance in cervical cancer patients.

Abstract
BACKGROUND High-risk human papillomavirus (HR-HPV) is a known cause of cervical cancer (CC). Latvia has a high incidence of CC compared with the average incidence in the European Union. This study aims to fill the data gap on the HR-HPV burden in Latvia, providing information on its prevalence and associated factors. METHODS The cross-sectional study was conducted from February 2021 to April 2022. Participants 25-70 years old visiting a general practitioner (general population) or those referred to a colposcopy clinic with changes in their cervical cytology (colposcopy population) collected vaginal self-sample and completed a paper-based questionnaire. Samples were analyzed with Cobas 6800 System (Roche) for HPV16, HPV18 and other HR-HPV (HPV31/33/35/39/45/51/52/56/58/59/66/68). Descriptive statistics for categorical variables were performed. The Chi-square test was used to determine for the statistical significance of differences in the proportions of the dependent variable between subgroups of the independent variable. Univariate and multivariate binary logistic regression were used to identify factors associated with positive HR-HPV status. Results were considered statistically significant at P < 0.05. RESULTS A total of 1274 participants provided a valid sample. The prevalence of any HR-HPV infection was 66.8% in the colposcopy group and 11.0% in the general population. Factors associated with positive HR-HPV status were marital status single/divorced/widowed (vs. married/cohabiting) [adjusted OR (aOR) 2.6; P = 0.003], higher number of lifetime sex partners [aOR 5.1 (P < 0.001) and 4.0 (P = 0.001)] for six or more and three to five partners in the general population; in the colposcopy group, the statistical significance remained only for Latvian ethnicity (vs. other) (aOR 1.8; P = 0.008) and current smoking (vs. never) (aOR 1.9; P = 0.01). CONCLUSION We documented a comparison to European Union HR-HPV infection burden in Latvia. Any HR-HPV positivity was significantly associated with sexual and other health behavior.

Abstract
Background Cervical cancer, one of the prevalent malignancies among females, is closely associated with human papillomavirus (HPV) infection. Homologous to the E6-AP carboxyl terminus (HECT) domain and ankyrin repeat containing E3 ubiquitin-protein ligase 1 (HACE1) plays pivotal roles in various cancers. This study aimed to elucidate the expression of HACE1 in cervical cancer and its correlation with clinical features. Methods From The Cancer Genome Atlas Cervical Squamous Cell Carcinoma and Endocervical Adenocarcinoma (TCGA-CESC) and Gene Expression Omnibus (GEO, GSE6791) datasets, we obtained RNA-Seq profiles and associated clinical information. Differential gene analysis was conducted using the R "limma" package. Implications for HPV infection and the overall survival (OS) of cervical cancer were determined by performing differential expression analysis and the Cox proportional hazards regression model. Immunohistochemical analyses were used to validate the expression in cervical cancer and normal cervical tissue. Further, nomogram was constructed to predict OS in cervical cancer. Whether the model was credible was evaluated according to receiver operating characteristic (ROC) curves and concordance curves. To further evaluate the potential functions of HACE1, we conducted functional enrichment analysis. Finally, we assessed methylation levels in HPV+ and HPV- patients in the TCGA-CESC dataset. Results Utilizing TCGA and GSE6791 datasets, we observed significant upregulation of HACE1 in cervical cancer patients, particularly linked to HPV infection. Immunohistochemical staining revealed enhanced HACE1 expression in tumor tissues. Further analysis demonstrated a significant positive correlation between elevated HACE1 and HPV-associated proteins (E1, E6, and E7). Moreover, high HACE1 expression was associated with adverse prognosis in cervical cancer patients. Multivariate Cox analysis indicated that HACE1 could serve as an independent prognostic factor. We developed a prognostic model integrating HPV subtypes, the International Federation of Gynecology and Obstetrics (FIGO) staging, and HACE1, exhibiting strong predictive efficacy for cervical cancer prognosis. Gene enrichment analysis indicated HACE1's potential involvement in multiple signaling pathways during cervical cancer progression, while the demethylation of cg03002526 in HPV-positive patients might contribute to HACE1 upregulation. Conclusions Our study reveals that HACE1 upregulation is associated with cervical cancer, particularly in HPV-positive patients. HACE1 emerges as an independent prognostic factor, linked to unfavorable outcomes.

Abstract
Background Vaccination against Human papillomavirus (HPV) is recommended to avoid HPV infections and its associated diseases, including cervical cancer. However, there is no awareness study among Bangladeshi population. Hence, this nationwide study was conducted to explore HPV vaccine awareness and its determinants among parents of eligible adolescent girls. Methods This study was conducted among the parents of daughters aged 9-15 years from 42 out of 64 randomly selected districts of Bangladesh between June 28 to August 2, 2023. A multistage sampling method was used to enroll 2151 study participants from all eight divisions of Bangladesh. A semi-structured questionnaire was used for face-to-face interviews in this study. The statistical software Stata (Version 17) was used for statistical analyses. Results The average age of the participants was 38.18 (±5.86) years. Only 22.32 % of the participants were aware of the HPV vaccine. Every additional year of age increased the likelihood of being aware of the HPV vaccine by 3 % (AOR: 1.03; 95%CI: 1.00-1.06). Participants residing in the urban area had 3.56 times higher odds of awareness than rural and semi-urban people. Businessmen and housewives had 60 % (AOR: 0.40; 95 % CI: 0.22-0.69) and 77 % (AOR: 0.23; 95 % CI: 0.16-0.33) lower odds in comparison to job holders. The lower-income group exhibited significantly higher odds of awareness (AOR: 0.25, 95%CI: 0.16-0.39) compared to the middle and the higher-income group. Participants who never went through routine health check-ups had 77 % lower odds of being aware than those who availed of regular routine check-ups (AOR: 0.23; 95%CI: 0.16-0.34). Conclusion Awareness of the HPV vaccine among the general population of Bangladesh is very low. Age, residence, occupation, monthly income, and routine medical check-ups were associated with HPV vaccine awareness. A nationwide awareness campaign would increase this awareness level among the Bangladeshi population, especially among the parents of daughters.

Abstract
Adoptive cell therapies involve infusing engineered immune cells into cancer patients to recognize and eliminate tumor cells. Adoptive cell therapy, as a form of living drug, has undergone explosive growth over the past decade. The recognition of tumor antigens by the T-cell receptor (TCR) is one of the natural mechanisms that the immune system used to eliminate tumor cells. TCR-T cell therapy, which involves introducing exogenous TCRs into patients' T cells, is a novel cell therapy strategy. TCR-T cell therapy can target the entire proteome of cancer cells. Engineering T cells with exogenous TCRs to help patients combat cancer has achieved success in clinical trials, particularly in treating solid tumors. In this review, we examine the progress of TCR-T cell therapy over the past five years. This includes the discovery of new tumor antigens, protein engineering techniques for TCR, reprogramming strategies for TCR-T cell therapy, clinical studies on TCR-T cell therapy, and the advancement of TCR-T cell therapy in China. We also propose several potential directions for the future development of TCR-T cell therapy.

Abstract
INTRODUCTION Long-term exposure to high-risk human papillomavirus (Hr-HPV) is a well-known necessary condition for development of cervical cancer. The aim of this study is to screen for Hr-HPV using vaginal self-sampling, which is a more effective approach to improve women's adherence and increase screening rates. METHODS This pilot study included a total of 100 Women living with HIV (WLWHIV), recruited from the Center for Listening, Care, Animation, and Counseling of People Living with HIV in Bamako. Hr-HPV genotyping was performed on Self-collected samples using the Cepheid GeneXpert instrument. RESULTS The median age of WLWHIV was 44 (interquartile range [IQR], 37-50) years. Approximately 92% of the study participants preferred self-sampling at the clinic, and 90% opted to receive result notifications via mobile phone contact. The overall prevalence of Hr-HPV among study participants was 42.6%, and the most frequent Hr-HPV sub-types observed were HPV18/45 (19.1%), HPV31/35/33/52/58 (13.8%), and HPV39/68/56/66 (12.8%), followed by HPV16 (5.3%), and HPV51/59 (5.3%). WLWHIV under 35 years of age had a higher frequency of Hr-HPV compared to their older counterparts, with rates of 30% versus 11.1% (p = 0.03). The duration of antiretroviral treatment showed an inverse association with Hr-HPV negativity, with patients on treatment for 15 (IQR, 10-18) years versus 12 (IQR = 7-14) years for Hr-HPV positive patients (95% CI [1.2-5.8], t = 3.04, p = 0.003). WLWHIV with baseline CD4 T-Cell counts below 200 exhibited a higher frequency of Hr-HPV compared to those with baseline CD4 T-Cell counts above 200 (17.9% versus 1.9%, p = 0.009). However, other demographics and clinical factors, such as marital status, age of sexual debut, parity, education, history of abortion, history of preeclampsia, and cesarean delivery, did not influence the distribution of Hr-HPV genotypes. CONCLUSION Our findings indicate that WLWHIV under the age of 35 years old exhibited the highest prevalence of Hr-HPV infection, with HPV18/45 being the most prevalent subtype. Additionally, WLWHIV with baseline CD4 T-Cell counts below 200 showed the highest infection rates.

Trends of cervical tumours amongst women from perspectives of demographic, socioeconomic and geographic indicators: retrospective ecological study in Czechia. Front Public Health 2024; 12:1347800. [PMID: 38813429 PMCID: PMC11133622 DOI: 10.3389/fpubh.2024.1347800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Accepted: 04/30/2024] [Indexed: 05/31/2024] Open
Abstract
Introduction For many infectious diseases, women are at higher risk and have a more severe disease course than men for many reasons, including biological differences, social inequalities, and restrictive cultural norms. The study focuses on infections with human papillomaviruses (HPV) in the form of cervical cancer as a gender-specific disease. The main goal is to evaluate cervical tumour incidence trends in the Czech female population in the HPV vaccination period 2012-2020 in relation to selected demographic, socioeconomic, and geographic indicators. Methods This is a retrospective ecological study. Data from publicly available databases about the incidence and mortality of cervical tumours (C53 Malignant neoplasm of cervix uteri, D06 Carcinoma in situ of cervix uteri according to ICD 10) and HPV vaccination rate were analysed and compared with demographic, socioeconomic and territorial data. Associations were searched using correlation analysis. Results There was a decreasing trend in the incidence of cervical cancer in the observed period. Regarding cervical tumours (C53, D06) and malignant neoplasm of cervix uteri incidence (C53), the decrease was approximately 11 and 20%, respectively. Differences between regions were observed in incidences and vaccination rates. Based on correlation analysis, indicators connected with urban/rural aspects, such as a share of urban population and population density, were statistically significant. The indicators related to higher cervical cancer incidence are the high unemployment rate of women, the high number of divorces, the high number of abortions, the high share of the urban population, the high number of students, and the high number of women with only primary education. On the other hand, the indicators related to lower cervical cancer incidence are the high gross domestic product (GDP), the high average gross monthly wage per employee, the high employment rate of women, the higher average age of mothers at birth, and the high number of women with tertiary education. Conclusion Results underline the problem of economically disadvantaged regions and families. Increasing vaccination rates, promoting regular screening for cervical cancer, and supporting awareness in the population, especially in regions with higher incidence rates, should be priorities for public health efforts.

Abstract
INTRODUCTION Human papillomavirus (HPV) presents a potential threat to the onset of carcinogenesis in the cervix, anogenital regions, and oropharynx. HPV encompasses over 200 types, with at least 12 having the potential to cause cancer, impacting the majority of sexually active individuals. In this current research, we explore the occurrence and spread of HPV genotypes. MATERIAL AND METHODS During this cross-sectional study conducted in Sanandaj, Iran from Feb 2022 to Aug 2023, diverse samples including oral, vaginal, and genital were collected from individuals referred to private laboratories in Sanandaj, Iran. After sample collection and DNA extraction (FAVORGEN, Taiwan), they were subjected to PCR and genotyping (MehrViru, Iran). The subsequent statistical analysis unveiled infection rates across different demographics and age groups. STATA (version 17) were used for statistical analysis. We examined infection rates across demographics using t-tests and Odds Ratio. RESULTS Overall, 26% (249) out of 950 cases tested positive for HPV, with 69% of these classified as high-risk. Among the examined population, 98% (933) were female, and 2% (17) were male. Females aged 31-40 exhibited the highest percentage of HPV prevalence (115/460) in the study with the majority of positive cases belonging to HR genotypes. The overall most frequent genotypes identified were 6, 16, 52, 53, 51, 58, and 56. HPV-16 exhibited the highest frequency among HR genotypes, accounting for 42 (17%) occurrences, followed by HPV-52 with a frequency of 32 (13%). CONCLUSION Our findings emphasize the significant prevalence of HPV among females, particularly in the 21-30 age group. The identification of high-risk genotypes, underscores the importance of targeted interventions for specific age cohorts. The age-stratified analysis highlights a consistent predominance of high-risk HPV across age groups, indicating the need for age-specific preventive measures. These results contribute valuable information for designing effective screening and vaccination strategies, to alleviate the impact of diseases associated with HPV.

Abstract
Background In Palestine, cervical cancer is the third most common gynaecological cancer, exhibiting higher mortality rates compared to regional counterparts. Late-stage diagnosis and limited awareness contribute to this disparity. This study aims to assess the awareness of Palestinian medical students regarding cervical cancer prevention. Methods A questionnaire-based survey involving 532 medical students from various Palestinian universities was conducted between October 2023 and December 2023. The survey encompassed closed-ended quantitative and demographic questions distributed through social media. Results The study was carried out on a group of 532 medical students (66.3% women and 33.6% men), (average age 21.7 years). Most students (77.7%) knew that the main risk factor for cervical cancer was human papillomavirus (HPV) infection. Participants doing the internship had the greatest knowledge, whereas students from the first year had the poorest knowledge about the main risk factors for cancer of the cervix. Only about half, 50.2% of all students, knew that in Palestine, there is no screening program. 84.4% of students correctly indicated that the cervical cancer screening test is a pap smear test. 41.4% of respondents knew that microscopic evaluation of the exfoliated cells from the vaginal part of the cervix is the screening test for cervical cancer which is used. Only about half of the students (45.1%) knew that there were no specific early symptoms of cervical cancer. Conclusions This study highlights the need for enhanced education, particularly regarding screening program awareness, among Palestinian medical students. Addressing these knowledge gaps is crucial for effective preventive strategies.

Abstract
BACKGROUND Cervical cancer is a common cancer that seriously affects women's health globally. The key roles of long non-coding RNAs (lncRNAs) in the onset and development of cervical cancer have attracted much attention. Our study aims to uncover the roles of lncRNA EBLN3P and miR-29c-3p and the mechanisms by which EBLN3P and miR-29c-3p regulate malignancy in cervical cancer. METHODS Tumor and adjacent normal tissues were collected from cervical cancer patients, and the expression of EBLN3P and miR-29c-3p were analyzed via RT-qPCR. The capacities of proliferation, migration, and invasion were assessed using CCK-8, wound healing and transwell assays. The interaction among EBLN3P, miR-29c-3p and TAF15 was determined by luciferase, RNA immunoprecipitation and RNA pull-down assays, respectively. A subcutaneous tumor xenograft mouse model was established to evaluate the functional role of EBLN3P in vivo. RESULTS The interaction and reciprocal negative regulation between EBLN3P and miR-29c-3p were uncovered in cervical cancer cells. Likewise, EBLN3P and miR-29c-3p expression patterns in tumor tissues presented a negative association. EBLN3P knockdown weakened cell proliferation, migration and invasion, but these effects were abrogated by miR-29c-3p depletion. Mechanistically, ALKBH5 might impaired EBLN3P stability to reduce its expression. EBLN3P functioned as a competing endogenous RNA (ceRNA) for miR-29c-3p to relieve its suppression of RCC2. Besides, EBLN3P enhanced RCC2 mRNA stability via interacting with TAF15. Furthermore, silencing of EBLN3P repressed the tumor growth in mice. CONCLUSION Altogether, lncRNA EBLN3P positively regulates RCC2 expression via competitively binding to miR-29c-3p and interacting with TAF15, thereby boosting proliferation, migration, and invasion of cervical cancer cells.

Abstract
OBJECTIVE This study aimed to check the expression profile of the C-X-C motif chemokine ligands (CXCLs)-C-X-C motif chemokine receptor 2 (CXCR2) axis in cervical cancer and to explore the cross-talk between cervical cancer cells and neutrophils via CXCLs-CXCR2 axis. METHODS Available RNA-sequencing data based on bulk tissues and single-cell/nucleus RNA-sequencing data were used for bioinformatic analysis. Cervical cancer cell lines Hela and SiHa cells were utilized for in vitro and in vivo studies. RESULTS Except for neutrophils, CXCR2 mRNA expression is limited in other types of cells in the cervical tumor microenvironment. CXCLs bind to CXCR2 and are mainly expressed by tumor cells. CXCL1, 2, 3, 5, 6, and 8, which are consistently associated with neutrophil infiltration, are also linked to poor prognosis. SB225002 (a CXCR2 inhibitor) treatment significantly impairs SiHa cell-induced neutrophil migration. CXCL1, CXCL2, CXCL5, or CXCL8 neutralized conditioned medium from SiHa cells have weaker recruiting effects. The conditioned medium of neutrophils from healthy donors can slow cancer cell proliferation. Conditioned medium of tumor-associated neutrophils (TANs) can drastically enhance cervical cancer cell growth in vitro and in vivo. CONCLUSIONS The CXCLs-CXCR2 axis is critical in neutrophil recruitment and tumor cell proliferation in the cervical cancer microenvironment.

Abstract
E6AP dysfunction is associated with Angelman syndrome and Autism spectrum disorder. Additionally, the host E6AP is hijacked by the high-risk HPV E6 to aberrantly ubiquitinate the tumor suppressor p53, which is linked with development of multiple types of cancer, including most cervical cancers. Here we show that E6AP and the E6AP/E6 complex exist, respectively, as a monomer and a dimer of the E6AP/E6 protomer. The short α1-helix of E6AP transforms into a longer helical structure when in complex with E6. The extended α1-helices of the dimer intersect symmetrically and contribute to the dimerization. The two protomers sway around the crossed region of the two α1-helices to promote the attachment and detachment of substrates to the catalytic C-lobe of E6AP, thus facilitating ubiquitin transfer. These findings, complemented by mutagenesis analysis, suggest that the α1-helix, through conformational transformations, controls the transition between the inactive monomer and the active dimer of E6AP.

Imiquimod Is Effective in Reducing Cervical Intraepithelial Neoplasia: A Systematic Review and Meta-Analysis. Cancers (Basel) 2024; 16:1610. [PMID: 38672691 PMCID: PMC11048968 DOI: 10.3390/cancers16081610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Revised: 04/14/2024] [Accepted: 04/17/2024] [Indexed: 04/28/2024] Open
Abstract
INTRODUCTION Topical Imiquimod is an immune response modifier approved for the off-label use of vulvar intraepithelial neoplasia. We conducted this systematic review and meta-analysis to investigate the efficacy and safety of Imiquimod in treating cervical intraepithelial neoplasia (CIN) and human papillomavirus (HPV)-positive patients. METHODS The study was prospectively registered (CRD420222870) and involved a comprehensive systematic search of five medical databases on 10 October 2022. We included articles that assessed the use of Imiquimod in cervical dysplasia and HPV-positive patients. Pooled proportions, risk ratios (RRs), and corresponding 95% confidence intervals (CIs) were calculated using a random effects model to generate summary estimates. Statistical heterogeneity was assessed using I2 tested by the Cochran Q tests. RESULTS Eight articles reported on 398 patients who received Imiquimod out of 672 patients. Among CIN-2-3 patients, we observed a pooled regression rate of 61% (CI: 0.46-0.75; I2: 77%). When compared, Imiquimod was inferior to conization (RR: 0.62; CI: 0.42-0.92; I2: 64%). The HPV clearance rate in women who completed Imiquimod treatment was 60% (CI: 0.31-0.81; I2: 57%). The majority of side effects reported were mild to moderate in severity. CONCLUSIONS Our findings indicate that topical Imiquimod is safe and effective in reducing cervical intraepithelial neoplasia and promoting HPV clearance. However, it was found to be inferior compared to conization. Imiquimod could be considered a potential medication for high-grade CIN patients and should be incorporated into guidelines for treating cervical dysplasia.

Abstract
Objectives: Cervical cancer prevention practices are desperately low in the Caribbean. This study aims to describe the cervical cancer stigma and to evaluate the influence of the prevention practices among the Caribbean non-patient population in Jamaica, Grenada, Trinidad and Tobago. Methods: A cross-sectional study involving 1,207 participants was conducted using a culturally trans-created Cancer Stigma Scale for the Caribbean context and supplemented with questions on cervical cancer and HPV/HPV vaccine knowledge and beliefs. Data collection took place online from October 2022 to March 2023. Results: Participants are young, single, well-educated, and have stable financial resources. Over a quarter (26.4%) agreed women with cervical cancer are more isolated in their country. Almost half (47%) of respondents agreed cultural background plays a big part in how they feel about illness and getting well. One in six participants believe women with cervical cancer are treated with less respect than usual by others in their country. Conclusion: Cancer stigma of cervical cancer exists in Jamaica, Trinidad and Tobago, and Grenada. Particularly, cultural background and social norms are closely linked to stigma.

Abstract
One of the deadliest malignant cancer in women globally is cervical cancer. Specifically, cervical cancer is the second most common type of cancer in Indonesia. The main infectious agent of cervical cancer is the human papilloma virus (HPV). Although licensed prophylactic vaccines are available, cervical cancer cases are on the rise. Therapy using multiepitope-based vaccines is a very promising therapy for cervical cancer. This study aimed to develop a multiepitope vaccine based on the E1 and E2 proteins of HPV 16, 18, 45, and 52 using in silico. In this study, we develop a novel multiepitope vaccine candidate using an immunoinformatic approach. We predicted the epitopes of the cytotoxic T lymphocyte (CTL) and helper T lymphocyte (HTL) and evaluated their immunogenic properties. Population coverage analysis of qualified epitopes was conducted to determine the successful use of the vaccine worldwide. The epitopes were constructed into a multiepitope vaccine by using AAY linkers between the CTL epitopes and GPGPG linkers between the HTL epitopes. The tertiary structure of the multiepitope vaccine was modeled with AlphaFold and was evaluated by Prosa-web. The results of vaccine construction were analyzed for B-cell epitope prediction, molecular docking with Toll like receptor-4 (TLR4), and molecular dynamics simulation. The results of epitope prediction obtained 4 CTL epitopes and 7 HTL epitopes that are eligible for construction of multiepitope vaccines. Prediction of the physicochemical properties of multiepitope vaccines obtained good results for recombinant protein production. The interaction showed that the interaction of the multiepitope vaccine-TLR4 complex is stable based on the binding free energy value -106.5 kcal/mol. The results of the immune response simulation show that multiepitope vaccine candidates could activate the adaptive and humoral immune systems and generate long-term B-cell memory. According to these results, the development of a multiepitope vaccine with a reverse vaccinology approach is a breakthrough to develop potential cervical cancer therapeutic vaccines.

Abstract
In the present study, the diagnostic value of high risk-human papillomavirus (HR-HPV) combined with colposcopy for the detection of cervical cancer and precancerous lesions was evaluated. A total of 397 patients with confirmed cervical disease were enrolled between August 2020 and December 2021. According to the pathological diagnosis, the patients were divided into cervical intraepithelial neoplasia grade I (CIN I; n=153 cases), CIN II (n=101 cases), CIN III (n=86 cases) and cervical cancer (n=57 cases) groups. The HR-HPV-positive rate of the patients with different lesion types was compared, and the consistency of colposcopy and pathological examination results were assessed. For cervical cancer and precancerous lesions, the diagnostic value and efficacy of HR-HPV testing, colposcopy and combined HR-HPV testing and colposcopy examination were compared using pathological examination results as the gold standard. The results of the present study demonstrated that in patients with cervical cancer, the positive rate of HR-HPV (100.00%; n=57/57) was higher than that in patients with precancerous lesions, and the positive rate of HR-HPV in patients with CIN I type (36.60%, n=56/153) was lower than that in patients with CIN II (83.17%, n=84/101) and CIN III (82.56%, n=71/86) types (P<0.05). There was no significant difference in the HR-HPV-positive rate between patients with CIN II and CIN III (P>0.05). Cohen's κ coefficient for colposcopy examination and pathological examination of patients with cervical cancer and precancerous lesions was 0.622, the diagnostic accuracy was 90.43% (n=359/397), the positive predictive value was 65.57% (n=40/61), and the negative predictive value was 94.94% (n=319/336). Receiver operating characteristic curve analysis demonstrated that the area under the curve of the combined examination in the diagnosis of cervical cancer and precancerous lesions was 0.904, which was higher than that of colposcopy (0.820) or HR-HPV testing (0.802) alone (P<0.05). The results of the present study indicated that HR-HPV detection combined with colposcopy has diagnostic value for cervical cancer and precancerous lesions.

Abstract
BACKGROUND Cervical cancer represents a significant health concern globally and is the fourth most common cancer among women, leading to substantial morbidity and mortality. The primary cause is persistent infection with high-risk human papillomavirus (HPV) types. Despite advancements in prevention, screening, diagnosis, and treatment, disparities in cervical cancer outcomes persist due to variations in screening accessibility and socioeconomic factors. This study focuses on women in the Kyrgyz Republic, highlighting regional disparities and the critical role of early detection. METHODS A retrospective data analysis was conducted on 1,338 women diagnosed with cervical cancer from 2012 to 2017 in the Kyrgyz Republic. Data were sourced from national health centers, focusing on sociodemographic metrics, clinical staging, and regional distributions. The study utilized statistical analysis to evaluate prevalence and mortality rates, employing the analysis of variance for comparison, significance, and analyzing trends over time. RESULTS The prevalence of cervical cancer in the Kyrgyz Republic increased from 97.5 per 100,000 females in 2012 to 105.3 per 100,000 in 2017, with mortality rates of 8.3-9.7%. Notably, regional disparities were evident, with Chui, Osh, Jalal-Abad, and Bishkek experiencing increased prevalence rates, while Talas, Issyk-Kul, Naryn, and Batken reported decreased prevalence. Screening programs, particularly the introduction of Pap smears, have been effective in reducing both prevalence and mortality rates in areas with broad population coverage. However, the study highlighted significant variations in outcomes across different regions, underscoring the importance of targeted prevention and screening efforts. CONCLUSIONS The study confirms the ongoing challenge of cervical cancer in the Kyrgyz Republic, emphasizing the need for improved screening and prevention strategies to address disparities in outcomes. The introduction of pilot screening programs represents a crucial step forward. However, the findings also point to the necessity for enhanced oncological literacy among primary care physicians and the implementation of comprehensive strategies to overcome socioeconomic and regional barriers to effective cervical cancer prevention and treatment. The reduction in prevalence observed in 2016 suggests progress, highlighting the potential impact of focused prevention and screening initiatives.

Abstract
Cervical cancer (CC) is the fourth most common cancer among women in the world and the second in Africa. CC is the third most frequent cancer and the first cause of cancer-related death among women in Cabo Verde, with an estimated incidence of 17 cases per 100,000 women. The mortality rate is around 10.5% and represents one of the largest percentages of all types of cancer diagnosed in women in the country. The high mortality rate can be explained by the absence of a national screening programme and a lack of human and physical resources. This study aims to determine the level of knowledge, attitudes and practices on CC among undergraduate female students in Cabo Verde in 2020. Methods A descriptive cross-sectional study, using a self-administered structured questionnaire, was conducted in six higher education institutions (HEI) in Cabo Verde between November and December 2020. A total of 618 female undergraduate students were recruited using a simple random sampling technique. Descriptive statistical data analysis was used to report the results. Results The response rate was 96.6% (n = 618). Most of the participants, 90.6% (549), were single, with average age of 21.79 years (SD =±4). Although most of the participants had already heard about CC (94.6%), most students showed a low knowledge about this disease (86.2%). Moreover, only 9.1% reported having been screened for CC. Conclusion Most undergraduate female students enrolled in HEI in Cabo Verde have poor knowledge and unfavourable attitudes toward CC. The level of knowledge is quite unsatisfactory. Within this context, the implementation of health policies focused on human papillomavirus education, prevention strategies, and CC screening is crucial.

Abstract
In this study, we examined the difference in the vaginal microbiota of women infected with human papillomavirus (HPV), according to menopausal status. A total of 75 cervicovaginal swab samples from 38 pre- and 37 postmenopausal women with HPV infection were obtained from the Korean HPV cohort. Vaginal microbiota analysis, including microbial diversity and specific bacterial abundances, was performed using 16S rRNA gene sequencing. The mean age of the pre- and postmenopausal women were 29.5 and 55.8 years, respectively (p < 0.0001). Lactobacillus spp. were predominant in both groups; however, a marked decrease was observed in postmenopausal women compared to premenopausal women (44.3% vs. 74.2%). Various anaerobic bacteria also showed a relatively high abundance in the postmenopausal group; Atopobium vagina and Gardnerella vaginalis significantly increased in postmenopausal women. Interestingly, no significant differences in bacterial richness were observed between the two groups. However, significant differences in beta-diversity were observed using the Bray-Curtis (p = 0.001), Generalized UniFrac (p = 0.002), Jensen-Shannon (p = 0.001), and UniFrac algorithms (p = 0.002). Theres results indicate that postmenopausal women with HPV infection exhibited a higher degree of vaginal dysbiosis than premenopausal women. Further, HPV-infected postmenopausal women had increased vaginal microbial diversity, characterized by an increase in anaerobic bacteria and concomitant depletion of Lactobacillus spp.

Abstract
Cervical cancer poses a significant global health challenge, ranking as the fourth most common cancer among women worldwide and resulting in approximately 300,000 deaths yearly, predominantly caused by high-risk human papillomavirus strains (HPV), mainly types 16 and 18. The scenario poses the urgent need of the hour to develop effective treatment strategies that can address the complexity of cervical cancer and multitargeted inhibitor designing that holds promise as it can simultaneously target multiple proteins and pathways involved in its progression and have the potential to enhance treatment efficacy, reduce the likelihood of drug resistance. In this study, we have performed multitargeted molecular docking of FDA-approved drugs against cervical cancer replication and maintenance proteins- Xenopus kinesin-like protein-2 (3KND), cell division cycle protein-20 (4N14), MCM2-histone complex (4UUZ) and MCM6 Minichromosome maintenance (2KLQ) with HTVS, SP and XP algorithms and have obtained the docking and MM\GBSA score ranging from -8.492 to -5.189 Kcal/mol and -58.16 to -39.07 Kcal/mol. Further, the molecular interaction fingerprints identified ALA, THR, SER, ASN, LEU, and ILE were among the most interacted residues, leaning towards hydrophobic and polar amino acids. The pharmacokinetics and DFT of the compound have shown promising results. The complexes were simulated for 100 ns to study the stability by computing the deviation, fluctuations, and intermolecular interactions formed during the simulation. This study produced promising results, satisfying the criteria that Mitoxantrone 2HCl can be a multitargeted inhibitor against cervical cancer proteins-however, experimental validation is a must before human use.Communicated by Ramaswamy H.

Abstract
BACKGROUND Cervicovaginal microbiome plays an important role in the persistence of HPV infection and subsequent disease development. However, cervicovaginal microbiota varied cross populations with different habits and regions. Identification of population-specific biomarkers from cervicovaginal microbiota and host metabolome axis may support early detection or surveillance of HPV-induced cervical disease at all sites. Therefore, in the present study, to identify HPV-specific biomarkers, cervicovaginal secretion and serum samples from HPV-infected patients (HPV group, n = 25) and normal controls (normal group, n = 17) in Xichang, China were collected for microbiome (16S rRNA gene sequencing) and metabolome (UHPLC-MS/MS) analysis, respectively. RESULTS The results showed that key altered metabolites of 9,10-DiHOME, α-linolenic acid, ethylparaben, glycocholic acid, pipecolic acid, and 9,12,13-trihydroxy-10(E),15(Z)-octadecadienoic acid, correlating with Sneathia (Sneathia_amnii), Lactobacillus (Lactobacillus_iners), Atopobium, Mycoplasma, and Gardnerella, may be potential biomarkers of HPV infection. CONCLUSION The results of current study would help to reveal the association of changes in cervicovaginal microbiota and serum metabolome with HPV infections.

Nat Commun 2024; 15:2271. [PMID: 38480731 PMCID: PMC10937927 DOI: 10.1038/s41467-024-46558-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 03/01/2024] [Indexed: 03/17/2024] Open
Abstract
T cell receptor (TCR)-engineered T cell therapy is a promising potential treatment for solid tumors, with preliminary efficacy demonstrated in clinical trials. However, obtaining clinically effective TCR molecules remains a major challenge. We have developed a strategy for cloning tumor-specific TCRs from long-term surviving patients who have responded to immunotherapy. Here, we report the identification of a TCR (10F04), which is human leukocyte antigen (HLA)-DRA/DRB1*09:01 restricted and human papillomavirus type 18 (HPV18) E784-98 specific, from a multiple antigens stimulating cellular therapy (MASCT) benefited metastatic cervical cancer patient. Upon transduction into human T cells, the 10F04 TCR demonstrated robust antitumor activity in both in vitro and in vivo models. Notably, the TCR effectively redirected both CD4+ and CD8+ T cells to specifically recognize tumor cells and induced multiple cytokine secretion along with durable antitumor activity and outstanding safety profiles. As a result, this TCR is currently being investigated in a phase I clinical trial for treating HPV18-positive cancers. This study provides an approach for developing safe and effective TCR-T therapies, while underscoring the potential of HLA class II-restricted TCR-T therapy as a cancer treatment.

Abstract
Background Cervical cancer poses a considerable worldwide health issue, where infection with the human papillomavirus (HPV) plays a vital role as a risk factor. Photodynamic therapy (PDT) is a minimally invasive treatment for HPV-related cervical lesions, which uses photosensitizers and light to selectively destroy abnormal cells. Objectives Our objective is to present a comprehensive overview of the different types of molecules employed in PDT to reduce the occurrence and fatality rates associated with cervical cancer. Design Scoping review and bibliometric analysis. Methods The article explores clinical trials investigating the efficacy of PDT in treating low-grade squamous intraepithelial lesion and high-grade squamous intraepithelial lesion, as well as preclinical approaches utilizing various molecules for PDT in cervical cancer. Furthermore, the article sheds light on potential molecules for PDT enhancement, examining their properties through computer modeling simulations, molecular docking, and assessing their advantages and disadvantages. Results Our findings demonstrate that PDT holds promise as a therapeutic approach for treating cervical lesions associated with HPV and cervical cancer. Additionally, we observe that the utilization of diverse dye classes enhances the anticancer effects of PDT. Conclusion Among the various molecules employed in PDT, functionalized fullerene exhibits a notable inclination toward overexpressed receptors in cervical cancer cells, making it a potential candidate for intensified use in PDT. However, further research is needed to evaluate its long-term effectiveness and safety.

Abstract
With cancer being a leading cause of death globally, there is an urgent need to improve therapeutic strategies and identify effective chemotherapeutics. This study aims to highlight the potential of crocetin, a natural product derived from certain plants, as an anticancer agent. It was conducted an extensive review of the existing literature to gather and analyze the most recent data on the chemical properties of crocetin and its observed effects in various in vitro and in vivo studies. The study particularly focused on studies that examined crocetin's impact on cell cycle dynamics, apoptosis, caspases and antioxidant enzyme levels, tumor angiogenesis, inflammation, and overall tumor growth. Crocetin exhibited diverse anti-tumorigenic activities including inhibition of tumor cell proliferation, apoptosis induction, angiogenesis suppression, and potentiation of chemotherapy. Multiple cellular and molecular pathways such as the PI3K/Akt, MAPK and NF-κB were modulated by it. Crocetin demonstrates promising anti-cancer properties and offers potential as an adjunctive or alternative therapy in oncology. More large-scale, rigorously designed clinical trials are needed to establish therapeutic protocols and ascertain the comprehensive benefits and safety profile of crocetin in diverse cancer types.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination is one of the crucial national vaccination programs aimed at reducing the prevalence of the diseases associated with HPV infections, which continue to pose a global health concern. However, a significant disparity exists in the distribution of HPV vaccine, particularly in low-middle income countries where the cost of HPV vaccine becomes a major obstacle. Thus, it is essential to ensure the availability of an economically feasible HPV vaccine, necessitating immediate efforts to enhance the cost-effectiveness of vaccine production. This study aimed to develop an efficient production system for the recombinant HPV type 52 L1 protein as HPV vaccine material using methylotrophic yeast Hansenula polymorpha expression system. RESULTS This study presents an in-depth examination of the expression and scale-up production of HPV type 52 L1 protein using DASGIP® parallel bioreactor system. The pHIPX4 plasmid, which is regulated by the MOX promoter, generates stable clones that express the target protein. Cultivation employing the synthetic medium SYN6(10) with controlled parameters (e.g. temperature, pH, feeding strategy, and aeration) produces 0.15 µg/mL of HPV type 52 L1 protein, suggesting a possibility for scaling up to a higher production level. CONCLUSION The scale-up production of HPV type 52 L1 protein using Hansenula polymorpha expression system described in this study provides an opportunity for an economical manufacturing platform for the development of the HPV vaccine.
