Abstract
AIM This study aimed to identify the prevalence and distribution of high-risk human papillomavirus (HR-HPV) types among Kazakhstani women with abnormal cervical cytology. METHODS A cross-sectional study was performed from May 2019 to June 2020. Cervical samples were collected from women in the different regions of Kazakhstan. RESULTS A total of 316 patients' samples were analysed for HR-HPV using real-time multiplex PCR. Cervical cytology abnormalities were reported according to the Bethesda classification. HPV detection by cytology showed a statistically significant association with HPV status and the number of HPV infection types (p < .05). Among women with abnormal cervical cytology, 62.4% were positive for HPV infection of those 79.4% had low-grade squamous intraepithelial lesions (LSIL), and 20.6% had high-grade squamous intraepithelial lesions (HSIL). Among patients with LSIL, 77.4% had HPV16 and 58.8% were infected with HPV18. Among patients with HSIL, 41.2% had HPV18 and 22.6% - HPV16. CONCLUSIONS There is a high prevalence of HR-HPV types among Kazakhstani women with abnormal cervical cytology. The most identified types were HPV16, 18, 31, 33 and 52. There is an emergency need to implement an HPV vaccination program to prevent cervical lesion development.

Abstract
Objective Cervical cancer screening coverage remains low in many countries worldwide. Self-sampling approach for cervical cancer screening has a good potential to improve the screening coverage. This study aims to compare different types of HPV self-sampling devices for cervical cancer screening to identify the most accurate and acceptable device(s). Methods A systematic review was performed on data extracted from all studies specific to HPV self-sampling devices by searching relevant articles in PubMed, Google Scholar, Scopus, Web of Science, ScienceDirect, Cochrane Library, and EBSCO published from 2013 to October 2023. The study was registered in PROSPERO (CRD42022375682). Results Overall, 70 papers met the eligibility criteria for this systematic review and were included in the analysis: 22 studies reported self-sampling devices diagnostic accuracy, 32 studies reported self-sampling devices acceptability and 16 studies reported both (accuracy and acceptability). The most popular self-sampling devices were Evalyn Brush, FLOQ Swab, Cervex-Brush, and Delphi Screener. Out of overall 38 studies analyzing self-sampling devices' diagnostic accuracy, 94.7% of studies reported that self-collected specimens provided sensitivity and specificity comparable with clinician-collected samples; acceptability of Evalyn Brush, FLOQ Swab, Delphi Screener, and Colli-Pee, varied between 84.2% and 100%. Conclusion The self-sampling approach has a good potential to increase cervical cancer screening coverage. Evalyn Brush, Cervex-Brush, FLOQ Swab, and Delphi Screener self-sampling devices for HPV detection were the most commonly utilized and found to be the most accurate, and patient-acceptable. HPV detection accuracy using these self-sampling devices had no significant difference compared to the sampling performed by healthcare providers.

Abstract
BACKGROUND Although recommended for all member states of World Health Organization, there is no national human papillomavirus vaccination program in Kazakhstan. Furthermore, there are no studies in Kazakhstan that evaluate the mothers' perception of human papillomavirus vaccines. OBJECTIVES This study aims to assess the knowledge and attitudes toward human papillomavirus vaccination among mothers in Kazakhstan and the factors associated with their attitudes. DESIGN A cross-sectional study was performed during the period of December 2021-February 2022. The STROBE guideline for cross-sectional studies was applied. METHODS Paper-based structured questionnaires were filled out by 191 mothers, 141 of whom had daughters. The attitude score was assessed as per the Likert-type scale. The Chi-square and Fisher's exact tests, with a significance value of < 0.05 were used to analyze the relationships between the characteristics of mothers and their attitude scores. RESULTS The following factors were significantly associated with mothers' attitudes toward human papillomavirus vaccination: a place of residence, family income, number of children, and refusal of vaccination for themselves (p < 0.005). Of all participants, only 45% of all mothers, 41% of mothers with a female, and 46% of mothers with male children had positive attitudes toward human papillomavirus vaccination. The child's gender was not a significant determinant. Overall, the level of knowledge about human papillomavirus vaccination was found to be low. The median total score is 0 out of 12 for women who have negative and neutral attitudes toward human papillomavirus vaccines. Among women who have positive attitudes toward HPV vaccines, the median score is around 3 points. CONCLUSION Before the implementation of the human papillomavirus vaccination program into the Kazakhstani national vaccination calendar, comprehensive and adequate information and education campaigns are required on the national level for parents and the population in general.

Abstract
Background. The high prevalence of HPV infection among Kazakhstani women and the absence of an HPV vaccination program are directly reflected in increasing rates of cervical cancer incidence and mortality. Kazakhstan made its first attempt at introducing the HPV vaccine in 2013, but was unsuccessful due to complications and low public acceptance. The attitudes of Kazakhstani women towards the vaccine were never measured. Therefore, this study aims to investigate the attitudes of women towards the HPV vaccine and determine factors associated with positive, negative, or neutral attitudes. Methods. A 29-item survey consisting of 21 demographic and contextual questions and 8 Likert-scale questions was distributed among women attending gynecological offices in four major cities of Kazakhstan from December 2021 until February 2022. Attitudes of women were measured based on their answers to the eight Likert-scale questions. Ordinal logistic regression was built to find associations between demographic characteristics and attitudes of women. Results. Two hundred thirty-three women were included in the final analysis. A total of 54% of women had positive attitudes towards the vaccine. The majority of women did not trust or had a neutral attitude towards the government, pharmaceutical industry, and traditional and alternative media. However, the trust of women was high in medical workers and scientific researchers. Women's age, education, number of children, effect of the 2013 HPV program, and trust in alternative medicine were included in the ordinal logistic model. Women with a low level of education, a high number of children, who believe in alternative medicine, and who were affected by the failed 2013 vaccination program were less likely to have a positive attitude towards the vaccine. Conclusions. Contrary attitudes towards HPV vaccination exist among Kazakhstani women, with approximately half having positive and almost half having negative or neutral attitudes towards the vaccine. An informational campaign that takes into consideration women's levels of trust in different agencies, as well as targets those who are the most uninformed, might help in a successful relaunch of the HPV vaccination program. However, more studies that cover a higher number of women are required.

Abstract
Cervical cancer remains one of the top causes of cancer-related morbidity and mortality all over the world. Currently, however, there are no published studies to assess the knowledge of HPV and cervical cancer in Kazakhstan. This study aimed to assess the awareness of HPV, the knowledge of HPV as a cause of cervical cancer, and the awareness of HPV vaccination among Kazakhstani women visiting gynecological clinics across the country. In addition, the study aimed to identify the factors associated with the awareness of HPV and the HPV vaccine and knowledge of HPV as a major cause of cervical cancer. This was a cross-sectional survey-based study with 2,272 women aged between 18–70 years attending gynecological clinics, who were administered paper-based questionnaires. Data analysis included descriptive statistics consisting of mean values, standard deviations, and frequencies, where applicable. Differences in categorical variables between groups were analyzed using the Chi-square test with a significance value of <0.005. Crude odds ratio (OR) and adjusted odds ratio (AOR) with 95% corresponding confidence intervals were calculated in regression analysis using univariate and multivariable logistic regression models. The mean age of participants was 36.33±10.09 years. More than half (53%) of the participants had been screened for cervical cancer. Among those who were aware of HPV, 46% knew that HPV causes cervical cancer and 52% were aware of the HPV vaccine. The key factors related to outcome variables were age, ethnicity, education, family, number of deliveries, and menarche. From a subgroup analysis, results from the HPV test and Pap smear test were factors related to dependent variables such as awareness of HPV and awareness of HPV vaccination.

Abstract
OBJECTIVES To conduct a nationwide high-risk human papillomavirus (HR-HPV) infection genotyping analysis of women attending gynecological clinics and identify factors associated with HR-HPV infection. METHODS A cross-sectional survey-based study with 759 participants. Demographics, lifestyle, and medical history data were collected by questionnaire completed by gynecologists during patients' visits. Cervical swabs were used for HPV genotyping using AmpliSens kit. Data analysis included descriptive statistics consisting of mean values, standard deviations, and frequencies, where applicable. Ordinal logistic regression was performed to identify factors associated with HPV infection status. RESULTS The mean age of participants was 36.51 ± 10.09 years. The majority of participants were aged 26-35 years. Less than half of the women (39%) were HPV positive; 26% had single HR-HPV, and 13% had multiple HR-HPV infection. The most prevalent HR-HPV genotypes were HPV-16 (54%), HPV-51 (7%), HPV-68 (7%), and HPV-18 (6%). Ordinal logistic regression demonstrated that older age, not being single, and having a history of sexually transmitted infections, decrease the odds of HPV infection. CONCLUSION This study identified high prevalence of HR-HPV among Kazakhstani women. Our results showed that adding HPV testing to compulsory cervical cancer screening in Kazakhstan could improve the screening program and decrease cervical cancer rates.

Abstract
OBJECTIVE Although cervical cancer could be prevented through medical screening, it remains one of the top causes of cancer-related morbidity and mortality all over the world. A number of factors may contribute to cervical cancer screening behaviour of women. The aim of this study was to investigate factors related to cervical cancer screening behaviour of women in Kazakhstan. METHODS This was a cross-sectional survey-based study with a total of 1189 participants. Women attending gynaecological clinics aged between 18 and 70 years were administered paper-based questionnaires about their awareness of cervical cancer, the associated risk factors, and cervical cancer screening. Student t test or Wilcoxon rank-sum test and chi-square test or Fisher's exact test, where appropriate, were used to determine associations with categorical independent variables. RESULTS The mean age of participants was 36.5 ± 10.1 years. Less than half (45.7%) of the participants had been screened for cervical cancer. The key factors related to the cervical cancer screening behaviour of women in this study included age, having a larger number of children, regular menstrual function, awareness of Pap smear test, and free screening programme for cervical cancer, and the causal association of human papillomavirus with cervical cancer. CONCLUSION This study revealed several significant factors predicting screening behaviour in Kazakhstani women. To improve the rate of screening, there is a need to increase public knowledge and awareness of cervical cancer and opportunities for the free screening programme in the female population of Kazakhstan.

Abstract
Mice deficient in TMEM218 (Tmem218(-/-) ) were generated as part of an effort to identify and validate pharmaceutically tractable targets for drug development through large-scale phenotypic screening of knockout mice. Routine diagnostics, expression analysis, histopathology, and electroretinogram analyses completed on Tmem218(-/-) mice identified a previously unknown role for TMEM218 in the development and function of the kidney and eye. The major observed phenotypes in Tmem218(-/-) mice were progressive cystic kidney disease and retinal degeneration. The renal lesions were characterized by diffuse renal cyst development with tubulointerstitial nephropathy and disruption of tubular basement membranes in essentially normal-sized kidneys. The retinal lesions were characterized by slow-onset loss of photoreceptors, which resulted in reduced electroretinogram responses. These renal and retinal lesions are most similar to those associated with nephronophthisis (NPHP) and retinitis pigmentosa in humans. At least 10% of NPHP cases present with extrarenal conditions, which most often include retinal degeneration. Senior-Løken syndrome is characterized by the concurrent development of autosomal recessive NPHP and retinitis pigmentosa. Since mutations in the known NPHP genes collectively account for only about 30% of NPHP cases, it is possible that TMEM218 could be involved in the development of similar ciliopathies in humans. In reviewing all other reported mouse models of NPHP, we suggest that Tmem218(-/-) mice could provide a useful model for elucidating the pathogenesis of cilia-associated disease in both the kidney and the retina, as well as in developing and testing novel therapeutic strategies for Senior-Løken syndrome.

Abstract
A rare combination of two histogenetically different tumours of the larynx in a male patient of 43, namely chondrosarcoma and squamous cell carcinoma is described. These tumours developed simultaneously, therefore the carcinoma could not result from the radiotherapy. No similar observation has been published in the literature.

Abstract
The NRAS protooncogene codes for a GTP binding/GTPase p21 protein which resides on the inner surface of the plasma membrane. Using a human cDNA probe for NRAS, we have assigned the gene to Syrian hamster chromosome 12 with the most likely localization being 12qa5.
