J Trace Elem Med Biol 2024; 86:127531. [PMID: 39270537 DOI: 10.1016/j.jtemb.2024.127531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 09/06/2024] [Accepted: 09/09/2024] [Indexed: 09/15/2024]
Abstract
BACKGROUND Cervical intraepithelial neoplasia (CIN) represents a premalignant state presumably related to perturbations in circulating levels of trace elements. MATERIALS AND METHODS Employing inductively coupled plasma mass spectrometry (ICP-MS), we quantified essential and toxic trace elements in the sera of 60 women diagnosed with CIN and 60 age-matched healthy counterparts. RESULTS Our investigation revealed a noteworthy higher levels in serum of Mn, Zn, and Pb, as well as lower levels in Ni, Se, Rb, and Mo levels within the CIN cohort. Levels of Mn, Zn, and Pb were higher by approximately 5.5-fold, 3.0-fold, and 7.5-fold, respectively, while Mo levels exhibited an approximate 4.5-fold reduction in CIN sera compared to the control group. While the study provided valuable insights into trace element variations, it's important to note that the adult Serbian population is considered Zn-deficient, so the Zn data should be interpreted with caution. Age stratification (30-40 vs. 40-50 vs. 50-60 years), smoking status (smokers vs. nonsmokers), and CIN severity (CIN 2 vs. CIN 3) yielded no significant disparities in elemental profiles. Among the 10 proposed ratios, 5 demonstrated a significant surge in CIN sera relative to controls: Mn/Se, Mn/Mo, Zn/Se, Zn/Mo, and Se/Mo. Correlation analysis of trace element levels revealed a predominantly consistent pattern between CIN cases and healthy subjects, except for Zn and its negative correlations (antagonistic interactions) with other analyzed trace elements. CONCLUSION Our findings underscore differences in serum levels of specific trace elements in CIN cases versus controls, implicating their potential involvement in the underlying pathophysiological cascades culminating in cervical neoplasms.

Abstract
Introduction Cervical cancer (CC) is the fourth most prevalent female cancer globally. Understanding its epidemiology is crucial for devising practical strategies suited to geographic and social contexts to attain the global eradication of CC. Hence, this study examined the latest evidence of risk factors contributing to CC development. Methods An independent literature search was conducted on PubMed using MESH terms. The primary sources were meta-analyses published from 2010 to 2023, which detail updated evidence on risk factors associated with CC. Additionally, the quality of the evidence was evaluated using the GRADE system and recommendations were made accordingly. Results The main risk factors related to the cause of CC include co-infections with other sexually transmitted infections, genetic markers, cervicovaginal microbiota, nutritional factors, comorbidities that affect the immune response, smoking, and the use of hormonal contraceptives with a quality evidence based on the GRADE scale moderate. Conclusions Since the necessary cause for CC is persistent cervicovaginal HPV, all the risk factors implicated in the causality of CC act as non-independent cofactors that increase the risk of CC. Thus, changes in public policies aimed at addressing these risk factors are highly recommended and can substantially decrease the risk of CC.

Abstract
Barriers to accessing offline healthcare may discourage patients from undergoing mammography screening. Online patient-provider communication (OPPC) offers a supplementary health resource that can complement traditional medical encounters and facilitate mammography screening. This study examines how offline healthcare barriers influence mammography screening, taking into account OPPC as an independent variable and cancer fatalism and patient activation as two mediators. Data from the 2017, 2018, and 2020 iterations of the Health Information National Trends Survey were used for this study. Results showed that OPPC was positively linked to mammography screening. Offline healthcare barriers had a negative association with patient activation and subsequent mammography behaviors. Moreover, offline healthcare barriers and OPPC were associated with mammography screening through serial mediation of cancer fatalism and patient activation. This study has important implications for encouraging mammography screening.

Abstract
Cervical cancer poses a significant global public health issue, primarily affecting women, and stands as one of the four most prevalent cancers affecting woman globally, which includes breast cancer, colorectal cancer, lung cancer and cervical cancer. Almost every instance of cervical cancer is associated with infections caused by the human papillomavirus (HPV). Prevention of this disease hinges on screening and immunization of the patients, yet disparities in cervical cancer occurrence exist between developed and developing nations. Multiple factors contribute to cervical cancer, including sexually transmitted diseases (STDs), reproductive and hormonal influences, genetics, and host-related factors. Preventive programs, lifestyle improvements, smoking cessation, and prompt precancerous lesion treatment can reduce the occurrence of cervical cancer. The persistency and recurrence of the cases are inherited even after the innovative treatments available for cervical cancer. For patient's ineligible for curative surgery or radiotherapy, palliative chemotherapy remains the standard treatment. Novel treatment strategies are emerging to combat the limited effectiveness of chemotherapy. Nanocarriers offer the promise of concurrent chemotherapeutic drug delivery as a beacon of hope in cervical cancer research. The primary aim of this review study is to contribute to a thorough understanding of cervical cancer, fostering awareness and informed decision-making and exploring novel treatment methods such as nanocarriers for the treatment of cervical cancer. This manuscript delves into cutting-edge approaches, exploring the potential of nanocarriers and other innovative treatments. Our study underscores the critical need for global awareness, early intervention, and enhanced treatment options. Novel strategies, such as nanocarriers, offer renewed optimism in the battle against cervical cancer. This research provides compelling evidence for the investigation of these novel therapeutic approaches within the medical field. Cervical cancer remains a formidable adversary, but with ongoing advancements and unwavering commitment, we move closer to a future where it is a preventable and treatable disease, even in the most underserved regions.

Abstract
Low-cost optical imaging technologies have the potential to reduce inequalities in healthcare by improving the detection of pre-cancer or early cancer and enabling more effective and less invasive treatment. In this Review, we summarise technologies for in vivo widefield, multi-spectral, endoscopic, and high-resolution optical imaging that could offer affordable approaches to improve cancer screening and early detection at the point-of-care. Additionally, we discuss approaches to slide-free microscopy, including confocal imaging, lightsheet microscopy, and phase modulation techniques that can reduce the infrastructure and expertise needed for definitive cancer diagnosis. We also evaluate how machine learning-based algorithms can improve the accuracy and accessibility of optical imaging systems and provide real-time image analysis. To achieve the potential of optical technologies, developers must ensure that devices are easy to use; the optical technologies must be evaluated in multi-institutional, prospective clinical tests in the intended setting; and the barriers to commercial scale-up in under-resourced markets must be overcome. Therefore, test developers should view the production of simple and effective diagnostic tools that are accessible and affordable for all countries and settings as a central goal of their profession.

Abstract
OBJECTIVE To assess whether nonsurgical therapies were related with clearance of cervical infection of high-risk human papilloma virus (hr-HPV) or regression of mild abnormal cytology related with hr-HPV. METHODS Until March 2023, we identified a total of 10 424 women with cervical infection of hr-HPV and 1966 women with mild abnormal cytology related with hr-HPV from 44 studies that met the inclusion criteria. RESULTS After systematically retrieving literature, we identified 2317 citations and 44 randomized controlled studies (RCT) were enrolled. Cumulative results suggested women with cervical infection of hr-HPV might benefit from nonsurgical therapies. Both the clearance of hr-HPV (OR: 3.83, I2 = 99%, p < 0.00001) and regression of mild abnormal cytology related with hr-HPV (OR: 3.12, I2 = 63%, p < 0.00001) were significantly higher than control group. Subgroup analysis stratified by systematic therapy, topical therapy, traditional Chinese medicines (TCMs), and presistent hr-HPV got consistent results. There was substantial heterogeneity between trials (I2 = 87% for clearance of hr-HPV and 63% for regression of cytology), sensitivity analysis was performed by excluding single study one by one, and found the cumulative results were stable and dependable. Both the funnel plots for clearance of hr-HPV and regression of abnormal cytology were asymmetrical, significant publication bias might exist. CONCLUSION Nonsurgical therapies might benefit women who had a cervical infection of hr-HPV with/without mild abnormal cytology related with hr-HPV. Both the clearance of hr-HPV and regression of abnormal cytology were significantly higher than control group. More studies with less heterogeneity were needed urgently to draw concrete conclusion.

Abstract
Background Improving the quality of care is vital to enhance outcomes for cervical cancer patients. However, the inequality of cervical cancer care was seldomly assessed. Methods We collected the data of cervical cancer burden from the Global Burden of Disease 2019 database, and constructed the Quality of Care Index (QCI) using principle component analysis. Then the disparity of QCI across regions and populations were evaluated. The association between cervical cancer screening coverage and QCI weas also explored. Results Quality of cervical cancer care was of disparity across regions with different development levels, with a widening gap between low-income regions and others. Cervical cancer QCI dropped rapidly after the age of 35. Cervical cancer screening coverage was positively associated with QCI, and this association was stronger in countries with low- and middle-development levels. Conclusions Regions with a low development level and the middle-aged women were vulnerable in QCI improvement. Higher screening coverage was associated with better cervical cancer QCI, implying that expanding cervical cancer screening coverage may be an effective strategy to improve the quality of cervical cancer care.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection. The implementation of primary prevention aims to reduce the burden of HPV infection and HPV-related disease. However, HPV-related diseases are still a concern, even in high-income countries. Approximately 570 000 new cervical cancer cases are diagnosed in Italy every year. Prophylactic HPV vaccines have been developed to minimize the spread of HPV. Growing evidence supports the administration of HPV vaccines (even just one dose) in reducing the prevalence of HPV infection and HPV-related disease including cancers. HPV vaccines are characterized by a high level of efficacy (>95%) in women who are naïve to HPV; however, they do not increase clearance in patients with ongoing HPV infection. With more than 200 million doses administered to date, HPV vaccines are considered to be safe and effective at preventing HPV-related infections and cancers. In this review we aim to review the current evidence regarding HPV vaccination and to describe trends in HPV vaccination coverage in Italy. In Italy, vaccination against HPV has been included in the National Immunization Plan (NIP) since 2007-2008. Using data abstracted from the Italian Ministry of Health, we analyzed changes in HPV vaccination coverage. We observed that HPV vaccines are underutilized and coverage rates are decreasing. Looking at the target population (females and males aged 11-12 years) in Italy, a decrease in coverage rates was observed. A call for action, improved HPV awareness, and education are the key elements to enhance the widespread adoption of HPV vaccination.

Abstract
OBJECTIVE Recent studies indicated that transmembrane protein 40 (TMEM40) is associated with several types of cancers but is not clear in cervical cancer (CC). The study aimed to examine the role of TMEM40 in CC and related mechanisms. METHODS The expression of TMEM40 in CC tissues and cell lines was studied with western blot and real-time quantitative RT-PCR. The effect of TMEM40 on proliferation was evaluated by CCK-8, EdU and colony formation assay. The migration, invasion, cell cycle and apoptosis of CC cells were studied with wound healing, transwell assays and flow cytometry. Tumor growth was evaluated in vivo using a xenogenous subcutaneously implant model. RESULTS The results revealed that the TMEM40 elevation in CC tissues and cell lines was closely correlated with tumor size and lymph node metastasis in clinical patients. Upregulation of TMEM40 with OE-TMEM40 vector promoted the invasion, migration and proliferation, inhibited the apoptosis and led to distinct S cell cycle arrest in CC cell lines. Silencing TMEM40 with shRNA inhibited the invasion, migration and proliferation, promoted apoptosis and led to a G0/G1 cell cycle arrest in CC cell lines. Silence of TMEM40 downregulated the expression of c-MYC, Cyclin D1, matrix metalloproteinase-1 (MMP-1) and matrix metalloproteinase-9 (MMP-9), but in contrast, activated p53 and several apoptosis related proteins such as p53, Caspase-3, Caspase-9 and PARP1. In addition, TMEM40 silencing dramatically decreased tumor growth in mice models. CONCLUSION The present study demonstrates that TMEM40 upregulation can be a potential prognostic biomarker and contribute to CC development.

Front Public Health 2022; 10:950610.

Abstract
Women who test positive for the human papillomavirus (HPV) but have normal cytology constitute the predominant subgroup of patients in the screening population in the post-vaccination era. The distribution of HPV genotypes changed dramatically, which was attributable to an increase in HPV vaccination coverage. These changes have created uncertainty about how to properly manage women with normal cytology, non-HPV16/18 infections, or persistent infections. Current recommendations include retesting and continued surveillance in the absence of HPV16/18 infection. However, these are not always applicable. The ability to implement genotyping or incorporate HPV16/18 with some additional high-risk HPV (HR-HPV) types for triage and management with the aim of identifying type-specific risks in this population could be acceptable. When the next set of guidelines is updated, generating potential triage strategies for detecting high-grade cervical lesions, such as the p16/Ki67 cytology assay and other alternatives that incorporate genotyping with newer tests, should be considered. Current clinical management is shifting to risk-based strategies; however, no specific risk threshold has been established in this population. Importantly, innovative triage testing should be evaluated in combination with primary screening and management. Furthermore, there is an untapped opportunity to coordinate HPV genotyping in combination with colposcopic characteristics to modify risk in this group. Hence, providing a more personalized schedule through the efficient application of risk stratification and improving the detection of pre-cancer and cancer is an option worth exploring.

Abstract
Background: Each year 604,127 new cases of cervical cancer (CC) are diagnosed, and 341,831 individuals die from the disease. It is the fourth most common cancer among women and the fourth most common cause of death from female cancers worldwide. The pathogenesis of CC is associated with human papillomavirus (HPV) infections and consists of several steps involving cell proliferation outside the human body’s control mechanisms. Strategies to prevent CC are based on screening and vaccination. Scope of the Review: The aim of this paper was to collect and analyze the available literature on the issue of CC prevention and the impact of the COVID-19 pandemic on its implementation. For this purpose, PubMed and Google Scholar databases were searched using keywords, such as “cervical cancer”; “HPV”; “prevention”; “prophylaxis”; “vaccination”; “screening” and “COVID-19” in different variations. Only articles published since 2018 were included in the study. Conclusions: Selected European countries have different CC prevention programs funded by national budgets. This translates into observed differences in the risk of death from CC (age-standardized rate Malta = 1.1, Poland = 5.9). COVID-19 pandemic due to disruption of CC screening may exacerbate these differences in the future. To improve the situation, new screening methods, such as p16/Ki67, HPV self-testing, and the use of artificial intelligence in colposcopic assessment, should be disseminated, as well as free HPV vaccination programs implemented in all countries. The search for new solutions is not without significance and entails ultra-sensitive screening tests for risk groups (mRNA E6/E7, SOX1/SOX14), HPV vaccines with shorter dosing schedules, and new therapeutic pathways using nanotheranostics.
