Objective: Globally, cervical cancer (CC) incidence is higher in rural areas than in urban areas that could be explained by the influence of many factors, including inequity in accessibility of the CC prevention measures. This review aimed to identify and analyze factors associated with a lack of cervical cancer screening and HPV vaccination programs in people living in rural areas and to outline strategies to mitigate these factors. Methods: The literature search encompassed two focal domains: cervical cancer screening and HPV vaccination among populations residing in rural areas, covering publications between January 1, 2004 to December 31, 2021 in the PubMed, Google Scholar, Scopus, and Cyberleninka databases, available in both English and Russian languages. Result: A literature review identified 22 sources on cervical cancer screening and HPV vaccination in rural and remote areas. These sources revealed similar obstacles to screening and vaccination in both high and low-income countries, such as low awareness and knowledge about CC, screening, and HPV vaccination among rural residents; limited accessibility due to remoteness and dearth of medical facilities and practitioners, associated with a decrease in recommendations from them, and financial constraints, necessitating out-of-pocket expenses. The reviewed sources analyzed strategies to mitigate the outlined challenges. Possible solutions include the introduction of tailored screening and vaccination campaigns designed for residents of rural and remote locations. New screening and vaccination sites have been proposed to overcome geographic barriers. Integrating HPV testing-based CC screening is suggested to counter the lack of healthcare personnel. HPV vaccination is essential for primary cervical cancer prevention, especially in rural and remote areas, as it requires less medical infrastructure. Conclusion: Certain measures can be proposed to improve the uptake of CC screening and HPV vaccination programs among rural residents, which are needed to address the higher prevalence of CC in rural areas. Further investigation into cervical cancer prevention in rural and remote contexts is necessary to ascertain the optimal strategies that promote health equity.

This systematic review aims to address the research gap in the performance of computational algorithms for the digital image analysis of HER2 images in clinical settings. While numerous studies have explored various aspects of these algorithms, there is a lack of comprehensive evaluation regarding their effectiveness in real-world clinical applications. We conducted a search of the Web of Science and PubMed databases for studies published from 31 December 2013 to 30 June 2024, focusing on performance effectiveness and components such as dataset size, diversity and source, ground truth, annotation, and validation methods. The study was registered with PROSPERO (CRD42024525404). Key questions guiding this review include the following: How effective are current computational algorithms at detecting HER2 status in digital images? What are the common validation methods and dataset characteristics used in these studies? Is there standardization of algorithm evaluations of clinical applications that can improve the clinical utility and reliability of computational tools for HER2 detection in digital image analysis? We identified 6833 publications, with 25 meeting the inclusion criteria. The accuracy rate with clinical datasets varied from 84.19% to 97.9%. The highest accuracy was achieved on the publicly available Warwick dataset at 98.8% in synthesized datasets. Only 12% of studies used separate datasets for external validation; 64% of studies used a combination of accuracy, precision, recall, and F1 as a set of performance measures. Despite the high accuracy rates reported in these studies, there is a notable absence of direct evidence supporting their clinical application. To facilitate the integration of these technologies into clinical practice, there is an urgent need to address real-world challenges and overreliance on internal validation. Standardizing study designs on real clinical datasets can enhance the reliability and clinical applicability of computational algorithms in improving the detection of HER2 cancer.

Cervical cancer (CC) continues to be a significant global health issue, which in part can be attributed to disparities in access to CC screening services. This study aims to conduct a trend of CC in Kazakhstan and to compare attitudes towards the screening program between women living in urban and rural areas. In the first stage, we conducted a trend study of CC indicators in Kazakhstan using official statistics. In the second stage, a cross-sectional study was conducted using a structured questionnaire to assess adherence to screening. The trend study reveals a decline in cervical cancer mortality rates (from 7.15 to 5.93 per 100,000 female inhabitants) over the period studied, while the incidence remains stable (from 18.51 to 19.38 per 100,000 female inhabitants). Regional variations in Period Prevalence rates were observed. Significant differences were found in screening participation rates between urban n = 41 (74%) and rural n = 23 (38%) women, p < 0.001, as well as awareness of the screening program (urban: n = 15 (27%), rural: n = 35 (58%), p < 0.001). The trend study highlights a decrease in cervical cancer mortality rates over the specified period, accompanied by a consistent incidence rate. Additionally, regional disparities in period prevalence rates of cervical cancer were observed. The primary factor contributing to the low adherence of rural women to screening was found to be a lack of awareness regarding the screening program. Therefore, increasing awareness about the importance of screening is crucial for improving adherence rates among rural women in Kazakhstan.

Background: Cervical cancer, predominantly caused by human papillomavirus, remains a major public health issue globally and in Kazakhstan, where it ranks among the most common cancers in women. A pilot HPV vaccination programme in Kazakhstan was suspended in 2017 due to mass parental refusals, and it is planned to be restarted in the coming years. This study aims to assess the knowledge, attitudes, barriers, and sources of information about HPV and the HPV vaccine among healthcare professionals in Kazakhstan. Methods: A cross-sectional study (December 2022–May 2023) involving 1189 healthcare professionals in Kazakhstan used a self-administered questionnaire. Statistical analysis included descriptive statistics, mean knowledge score, between-group comparisons, and binary logistic regression to identify factors linked to higher knowledge and vaccine recommendation. Results: The study found that the average knowledge score for HPV and the HPV vaccine among participants was 11 out of a possible 18. Correct answers to the questionnaire were observed more frequently among physicians than among nurses (p < 0.001). In our study, 72.6% of healthcare professionals expressed a positive intention to recommend the HPV vaccine. The likelihood of recommending the HPV vaccine was significantly higher among those with higher knowledge of HPV and its vaccine (OR 1.8; 95% CI 1.3–2.5; p < 0.001), those familiar with cervical cancer patients (OR 2.0; 95% CI 1.5–2.8; p < 0.001), and those with positive attitudes towards the COVID-19 vaccine and childhood vaccination (OR 2.3 and 1.5, respectively). Healthcare professionals identified key barriers to HPV vaccination, including public mistrust (49.4%), fear of side effects (45.9%), and insufficient knowledge among healthcare professionals themselves (30.3%). Information from the internet, including articles and journals, was the most commonly used source of information, followed by social media and colleagues. Conclusions: The disparities identified call for a tailored, multifaceted communication strategy that addresses the diverse needs of health professionals to address the differences in awareness between different groups, in order to ensure successful implementation and coverage of HPV vaccination across Kazakhstan.

Introduction Human papillomavirus (HPV) is a prevalent sexually transmitted infection linked to certain types of malignant neoplasms, notably cervical cancer (CC). In Kazakhstan, a high prevalence of high oncogenic HPV types (HR-HPV) has been observed, and CC ranks as the second most common malignancy among women with a crude incidence rate of 18.3 cases per 100 000 women. The HPV vaccine, developed as the primary prevention measure against HPV infection, including the most prevalent HR-HPV, received approval from the WHO in 2009. In 2014, Kazakhstan initiated HPV vaccination as a pilot project in four sub-national regions; however, it was later in 2017 discontinued due to widespread parental refusal influenced by negative media reports. This study aims to examine knowledge, attitudes, information sources, barriers to HPV vaccination and factors associated with HPV vaccination hesitancy among different target groups in Kazakhstan prior to the HPV vaccine re-launch announced by the Ministry of Health. Methods and analysis This mixed-method-designed research comprises quantitative and qualitative components. Data on HPV awareness, attitudes towards HPV vaccination and sources of information will be collected through an online survey administered by parents and legal guardians, health professionals, and schoolteachers in the Republic of Kazakhstan between January 2023 and January 2024. Additionally, qualitative data on Kazakhstani parental beliefs and attitudes toward HPV vaccination will be collected through online focus group discussions. Ethics and dissemination of results The study has been approved by the local ethics committee at the Kazakhstan Medical University “Higher School of Public Health” (KMU “KSPH”) (No. 138 of 31.05.2021). The results will be reported in publications, at conferences among researchers and healthcare and school education professionals in Kazakhstan, and internationally.
