Cervical Cancer Screening Among Female Medicaid Beneficiaries With and Without Schizophrenia.

BACKGROUND AND HYPOTHESIS: In the United States, women with schizophrenia face challenges in receiving gynecologic care, but little is known about how cervical cancer screening rates vary across time or states in a publicly insured population. We hypothesized that women Medicaid beneficiaries with schizophrenia would be less likely to receive cervical cancer screening across the United States compared with a control population, and that women with schizophrenia and other markers of vulnerability would be least likely to receive screening. STUDY DESIGN: This retrospective cohort study used US Medicaid administrative data from across 44 states between 2002 and 2012 and examined differences in cervical cancer screening test rates among 283 950 female Medicaid beneficiaries with schizophrenia and a frequency-matched control group without serious mental illness, matched on age and race/ethnicity. Among women with schizophrenia, multivariable logistic regression estimated the odds of receiving cervical cancer screening using individual sociodemographics, comorbid conditions, and health care service utilization. STUDY RESULTS: Compared to the control group, women with schizophrenia were less likely to receive cervical cancer screening (OR = 0.76; 95% CI 0.75-0.77). Among women with schizophrenia, nonwhite populations, younger women, urban dwellers, those with substance use disorders, anxiety, and depression and those connected to primary care were more likely to complete screening. CONCLUSIONS: Cervical cancer screening rates among US women Medicaid beneficiaries with schizophrenia were suboptimal. To address cervical cancer care disparities for this population, interventions are needed to prioritize women with schizophrenia who are less engaged with the health care system or who reside in rural areas.

Utilizing the open-source programming language Python to create interactive Quality Assurance dashboards for diagnostic and screening performance in Cytology.

INTRODUCTION: Effective feedback on cytology performance relies on navigating complex laboratory information system data, which is prone to errors and lacks flexibility. As a comprehensive solution, we used the Python programming language to create a dashboard application for screening and diagnostic quality metrics. MATERIALS AND METHODS: Data from the 5-year period (2018-2022) were accessed. Versatile open-source Python libraries (user developed program code packages) were used from the first step of LIS data cleaning through the creation of the application. To evaluate performance, we selected 3 gynecologic metrics: the ASC/LSIL ratio, the ASC-US/ASC-H ratio, and the proportion of cytologic abnormalities in comparison to the total number of cases (abnormal rate). We also evaluated the referral rate of cytologists/cytotechnologists (CTs) and the ratio of thyroid AUS interpretations by cytopathologists (CPs). These were formed into colored graphs that showcase individual results in established, color-coded laboratory "goal," "borderline," and "attention" zones based on published reference benchmarks. A representation of the results distribution for the entire laboratory was also developed. RESULTS: We successfully created a web-based test application that presents interactive dashboards with different interfaces for the CT, CP, and laboratory management (https://drkvcsstvn-dashboards.hf.space/app). The user can choose to view the desired quality metric, year, and the anonymized CT or CP, with an additional automatically generated written report of results. CONCLUSIONS: Python programming proved to be an effective toolkit to ensure high-level data processing in a modular and reproducible way to create a personalized, laboratory specific cytology dashboard.

Cytologic Parameters in Predicting the Outcome of Atypical Glandular Cells on Papanicolaou Smears: A Single-Institutional Experience.

Background: Atypical glandular cells (AGCs) diagnosis on Pap (Papanicolaou) smears are uncommon and may represent various benign and malignant lesions. Objective: This study aims to report the incidence of AGC on Pap smear, to study the relationship of AGC with malignancy, and to determine cytomorphological features that help in predicting malignancy. Materials and Methods: Retrospective analytical study conducted in the Department of Oncopathology at Tertiary Cancer and Research Institute. In this retrospective study, we included cases diagnosed with AGC between July 2017 to July 2022. All slides were reviewed and subclassified according to the Bethesda 2014 classification system (TBS). The predetermined cytomorphological features observed in the smears were recorded. The follow-up histopathological diagnoses of the cases were retrieved. The significant cytomorphological and clinicopathological findings for malignancy were determined. Results: Pearson χ2 test with SPSS software version 22 to compare cytologic features of cases with benign and malignant follow-up. The significant cytomorphological features observed in neoplastic cases were cells in 3-dimensional clusters, nuclear overlapping, reniform nucleus, irregular nuclear membrane, increased nuclear size, single macronucleoli, engulfed neutrophils, and prominently vacuolated cytoplasm. Conclusions: The diagnosis of AGC on cytology is associated with clinically significant lesions, and cytomorphologic parameters can be used to predict the benign and malignant outcome.

Low uptake of Pap test as a cervical cancer screen among Saudi women: Findings from a national survey.

OBJECTIVE: The present study aimed to assess the current knowledge and uptake of Papanicolaou (Pap) tests for cervical screening among Saudi women, including barriers to undergoing the test and the availability of related services. METHODS: A cross-sectional study was conducted using a health questionnaire administered through the Absher portal between April 1, 2019, and March 31, 2020. The questionnaire consisted of five questions and took less than 5 min to complete. Descriptive and inferential statistics were employed to analyze demographic variables, and chi-square tests were used to examine the association between these variables and Pap test uptake. RESULTS: The questionnaire included 8194 Saudi women, with the majority from Makkah (24.40%), Riyadh (21.92%), and Eastern (14.44%) regions. Only 22.52% of respondents had ever received a Pap test, and among them, 17.48% did so based on their physician's recommendation. Private clinics accounted for 10.73% of Pap test locations, while public clinics accounted for 8.97%. The primary reasons for not undergoing the test were lack of knowledge regarding its importance (40.24%) and lack of information from physicians (16.96%). Knowledge of the Pap test as a cervical screening method was significantly associated with marital status, Saudi region, and age group. CONCLUSIONS: This study revealed low awareness of the Pap test for cervical screening among Saudi women, particularly in younger age groups. Targeted educational initiatives are essential to increase awareness and emphasize the significance of regular screenings, especially among younger individuals, to enhance early detection and reduce the burden of cervical cancer in Saudi Arabia.

Cervical cancer screening barriers and facilitators from the perspectives of women with a history of criminal-legal system involvement and substance use.

BACKGROUND: The wide availability of routine screening with Papanicolaou (Pap) tests and vaccinations against human papillomavirus has resulted in a decline in rates of cervical cancer. As with other diseases, however, disparities in incidence and mortality persist. Cervical cancer, is found more often, at later stages, and has worse outcomes in people who live in rural areas, identify as Black or Hispanic, and in people who are incarcerated. Studies report 4-5 times higher rates of cervical cancer incidence in people detained in jails and prisons than in community-based samples. Studies to explain cervical cancer differences have been inconclusive, though there is broad consensus that issues of access play a role. In this study, we sought to learn more from people who have a history of criminal-legal system involvement and substance use about what barriers and facilitators they perceive in accessing cervical cancer preventive health and other support services in the community. RESULTS: We conducted semi-structured interviews with open-ended questions by telephone with 20 self-identified women, ages 22-58, in Birmingham, Alabama. Interviews were audio recorded and transcribed and the transcripts analyzed using immersion-crystallization techniques. Our team identified two main themes, making connections: the importance of interpersonal communication, which stressed barriers and facilitators related to what makes for effective and humanistic interactions in cervical health prevention and other services, and getting it done: the logistics of access and availability, which highlighted elements of cost and payment; scheduling; transportation; and clinic policies. CONCLUSIONS: People with a history of criminal-legal system involvement and substance abuse meet with a variety of enabling and impeding factors at personal and interpersonal as well as systemic levels in obtaining cervical health services. To better ensure that women in this high-risk group have equitable access to cervical cancer prevention and treatment-and thus better cancer outcomes-will require multilevel efforts that include an emphasis on improving the human connection in health care encounters and improving the nuts-and-bolts logistics related to accessing that care.

Enhancing Cervical Cancer Screening: Review of p16/Ki-67 Dual Staining as a Promising Triage Strategy.

Cervical cancer, primarily caused by high-risk human papillomavirus (HR-HPV) types 16 and 18, is a major global health concern. Persistent HR-HPV infection can progress from reversible precancerous lesions to invasive cervical cancer, which is driven by the oncogenic activity of human papillomavirus (HPV) genes, particularly E6 and E7. Traditional screening methods, including cytology and HPV testing, have limited sensitivity and specificity. This review explores the application of p16/Ki-67 dual-staining cytology for cervical cancer screening. This advanced immunocytochemical method allows for simultaneously detecting p16 and Ki-67 proteins within cervical epithelial cells, offering a more specific approach for triaging HPV-positive women. Dual staining and traditional methods are compared, demonstrating their high sensitivity and negative predictive value but low specificity. The increased sensitivity of dual staining results in higher detection rates of CIN2+ lesions, which is crucial for preventing cervical cancer progression. However, its low specificity may lead to increased false-positive results and unnecessary biopsies. The implications of integrating dual staining into contemporary screening strategies, particularly considering the evolving landscape of HPV vaccination and changes in HPV genotype prevalence, are also discussed. New guidelines and further research are necessary to elucidate the long-term effects of integrating dual staining into screening protocols.

Socioeconomic disparities in Papanicolaou test utilization in Western Iran.

BACKGROUND: Cervical cancer remains the fourth most frequently diagnosed cancer among women, and its impact is particularly significant in women residing in less developed countries. This study aims to assess socioeconomic inequality in using Papanicolaou tests, commonly known as Pap tests, which are crucial for detecting cervical cancer. The research also seeks to decompose this inequality, identifying its contributing factors. This investigation is conducted within a sizable population-based study focused on the Kurdish population, with an additional examination of potential variations between urban and rural areas. METHOD: The study utilized baseline data from the Ravansar Non-Communicable Disease Cohort Study (RaNCD), involving 3,074 ever-married women aged 35-65. Asset data was employed to determine socioeconomic status (SES), and Principal Component Analysis was applied. The uptake of Papanicolaou tests was assessed for inequality using the Concentration Index (Cn). Additionally, decomposition analysis was conducted to identify and understand the factors contributing to socioeconomic inequality. RESULTS: The study found that overall, 86% of women reported having undergone cervical cancer screening at least once in their lifetime. The Concentration Index (Cn) for the total population was 0.21 (p < 0.0001), indicating a higher concentration of Papanicolaou test uptake among wealthier groups. In urban areas, the Cn was 0.34 (p < 0.0001), reflecting a significant concentration among the rich. However, in rural areas, the Cn was -0.10 (p = 0.3006), suggesting no significant socioeconomic inequality. Factors such as socioeconomic status (SES), education, and age contributed to reducing inequality, explaining 62.7%, 36.0%, and 1.7% of the observed inequality, respectively. Interestingly, place of residence had a negative influence on inequality. CONCLUSION: The uptake of Papanicolaou tests varies across different socioeconomic status levels, with a higher concentration among wealthier groups. The results enable health policymakers and researchers to tailor health intervention toward increasing public awareness, especially among women with lower levels of education women in economically deprived groups.

Knowledge of cervical cancer screening among Omani women attending a university teaching hospital: a cross-sectional study.

OBJECTIVES: To assess knowledge, attitudes, and practices regarding cervical cancer and Pap smear screening among Omani women attending a tertiary clinic in Muscat, Oman, and to establish correlations with selected sociodemographic factors. METHODS: An observational, cross-sectional study was carried out among Omani women aged 18-50 years old attending the outpatient clinic of the Department of Obstetrics and Gynecology, Sultan Qaboos University Hospital, from October 2019 to February 2020. A validated Arabic-language questionnaire was utilized to collect data regarding the participants' sociodemographic characteristics, their knowledge of cervical cancer and related risk factors, and their knowledge, attitudes, and practices related to cervical cancer screening and Pap smear testing. RESULTS: Of the 380 respondents, 86 and 55% had previously heard of cervical cancer and Pap smear testing, respectively; however, only 26% were knowledgeable concerning these topics. Knowledge scores were significantly associated with various sociodemographic factors, including marital status and a previous awareness of cervical cancer (odds ratio: > 1, p < 0.05). Only 21% had themselves previously undergone Pap smear testing; however, 75% reported being willing to undergo such screening in future. CONCLUSIONS: Knowledge regarding cervical cancer-related risk factors and Pap smear screening was poor among a cohort of Omani women attending a tertiary clinic in Muscat, Oman. This may play a role in the increased frequency of cervical cancer cases observed in Oman over recent years. As such, a well-structured public education program is recommended to raise awareness of this issue.

Our experience diagnosing 225 patients with cervical glandular lesions: current technologies, lessons learned, and areas for improvement.

OBJECTIVE: To explore the relative sensitivity of different methods for detecting cervical glandular lesions. METHODS: A total of 225 patients with cervical glandular lesions diagnosed from January 2018 to February 2023 were retrieved from the pathology database of Guangdong Maternal and Child Health Hospital, and their clinicopathological features were reviewed. RESULTS: Four human papillomavirus (HPV) genotypes: HPV18, 16, 45, and 52, dominated all glandular lesions, and accounting for 74.10% of HPV-positive tumors. Furthermore, 36.89% of abnormal squamous cells were diagnosed as abnormal based on cytological examinations leading to the detection of cervical glandular lesions; only 16.89% were diagnosed based on the initial detection of abnormal glandular cytology. The most common abnormal cervical screening result was ASC-US on cytology (14.22%), followed by HSIL (11.56%). Only few number of patients were diagnosed with or suspected of having cervical adenopathy via a Pap test (18.22%). Nearly one-third of cervical glandular lesions cases were not detected on the Pap test; but were diagnosed upon cervical biopsy or based on the histological examination of ECC, LEEP, or CKC specimens. The LEEP or CKC biopsy specimens had negative margins in 49 cases (40.83%), while the margins were positive in the other 71 cases (59.17%). Five cases (10.20%) with negative margins still had residual lesions following total hysterectomy, and 19 (26.76%) with positive margins had no residual lesions after total hysterectomy. CONCLUSION: The ability to detect cervical glandular lesions varies for routine HPV genotyping, Pap test, or biopsy/ECC, with different sensitivities and advantages and disadvantages for each method.

Predictive Value of Various Atypical Cells for the Detection of Human Papillomavirus in Cervical Smears.

It is thought that numerous genotypes of human papillomavirus (HPV) are associated with various atypical cells, such as multinucleated cells, koilocytes, binucleated cells, parakeratotic cells, and giant cells, in the cervix. We previously showed the specificity of HPV genotypes for koilocytes and multinucleated cells. Therefore, in this study, we analyzed the association among HPV genotypes and binucleated cells, parakeratotic cells, and giant cells in Papanicolaou (Pap) smears. We detected HPV genotypes and atypical cells in 651 cases of liquid-based cytology with an abnormal Pap smear. The HPV genotypes associated with atypical cells were evaluated using stepwise logistic regression with backward elimination and a likelihood ratio test for model construction. Polymerase chain reaction was used to determine the HPV genotypes in whole liquid-based cytology samples and microdissected cell samples from Pap smear slides. Binucleated cells were significantly associated with HPV genotype 42. Moreover, parakeratotic cells were significantly associated with certain HPV genotypes, such as HPV40. However, it was difficult to detect specific HPV genotypes by the manual microdissection-polymerase chain reaction method despite the presence of binucleated cells and parakeratotic cells. Thus, the presence of binucleated cells, parakeratotic cells, and giant cells in Pap smears may not be predictive of cervical lesions above low-grade squamous intraepithelial lesions or infection with highly carcinogenic HPV genotypes.

Self-reported participation in cervical cancer screening among Polish women in 2004-2019.

OBJECTIVES: We aimed to assess self-reported participation in cervical cancer screening among Polish women between 2004 and 2019 and to identify the groups with the lowest participation rate. MATERIAL AND METHODS: Data on declared participation in cervical cancer screening were obtained from the European Health Interview Survey from 2004 to 2019. RESULTS: In 2019, 86.7% of Polish women aged ≥ 15 years declared that they had ever undergone a Pap test. Compared to 2004, the coverage of ever-screened women improved by 16.6 percentage points. The proxy population coverage was 72.9%. The highest proportion of women who underwent a Pap smear in the last three years was observed among those aged 35-44 years and 25-34 years (84.0% and 83.2%, respectively), and the lowest among women aged ≥ 75 years (20.5%). The proportion screened within the last three years also varied by education (up to lower secondary education 26.4%, up to post-secondary non-tertiary education 62.8%, and the highest level of education 83.7%), urbanization (large cities 66.7%, suburbs, and smaller cities 62.8%, and rural areas 59.0%), income (poorest households 42.5%, wealthiest households 70.6%), and declared health status (best 68.9%, worst 41.4%). The lowest participation in screening was observed in the southeastern regions and the highest in the northwestern regions of Poland. CONCLUSIONS: In Poland, in 2019, the approximate coverage of cervical cancer screening was high compared to other European countries and has improved over the last 15 years. A complete screening registry is required to confirm questionnaire-based self-reported data. Targeted interventions should be implemented to address low participation in the identified regions and socioeconomic groups.

Implementation rate and related factors of confirmatory tests following an abnormal Pap smear: a nationwide study from the National Health Insurance.

OBJECTIVE: This study aims to investigate the implementation rate and influencing factors of confirmatory tests for women with abnormal cervical cytology results in the Korean nationwide cervical cancer screening program. METHODS: The National Health Insurance Service (NHIS) database was utilized to identify all Korean women who have participated in the Korean nationwide cervical cancer screening program from January 2011 and December 2021 using the NHIS database. Multiple logistic regression analysis was performed to estimate the multivariate odds ratio and evaluate the patients' characteristics. RESULTS: The rate of abnormal Papanicolaou (Pap) smears showed an initial increase from 2011 to 2015 and subsequently reached a plateau after 2016. When examining specific subcategories, cases of atypical squamous cells of undetermined significance (ASC-US) increased from 28,546 cases (1.1%) in 2011 to 62,850 cases (1.7%) in 2021. In contrast, cases of HSIL and SCC declined from 3,535 cases (0.14%) to 2,763 cases (0.07%) and from 383 cases (0.01%) to 179 cases (0.005%), respectively. Furthermore, the implementation rate of confirmatory tests for women with abnormal cytology increased from 8,865 cases (21.0%) in 2011 to 39,045 cases (51.2%) in 2021. Regarding the specific subcategory of ASC-US, the number of confirmatory tests exhibited a substantial increase from 4,101 cases (14.4%) in 2011 to 30,482 cases (48.5%) in 2021. For SCC, there was no significant change, with 216 cases (56.4%) in 2011 and 102 cases (57.0%) in 2021. The implementation rate of confirmatory tests was found to be significantly associated with results of abnormal Pap smear, age, and residence. Notably, economic status did not emerge as a significant factor affecting the likelihood of undergoing confirmatory tests. CONCLUSIONS: The severity of abnormal Pap smear results is a reliable indicator of the probability of undergoing a confirmatory test. Additional endeavors are required to improve the implementation rate among women who have received abnormal Pap smear results.

Barreras asociadas con la falta de interés en el resultado del Papanicolaou / Barriers associated with lack of interest in the Papanicolaou result

Resumen OBJETIVO: Determinar las barreras personales, culturales e institucionales asociadas con la falta de interés de las pacientes en conocer (recoger) el reporte de la prueba de Papanicolaou. MATERIALES Y MÉTODOS: Estudio observacional, analítico, de casos y controles efectuado en el Centro de Salud Moyopampa, distrito de Lurigancho-Chosica, en Lima, Perú, durante diciembre del 2022. La muestra fue de casos (pacientes que no recogieron el reporte de la última prueba de Papanicolaou practicada en los dos últimos años) y controles (pacientes que sí acudieron a recibir su reporte). Parámetros de estudio: barreras personales, culturales e institucionales registradas en un cuestionario previamente validado. La asociación entre variables se estimó con χ² de Pearson y prueba exacta de Fisher, razón de momios con intervalo de confianza del 95% y p < 0.05. RESULTADOS: Se estudiaron 138 casos y 138 controles. En relación con las barreras personales, la edad de 25 a 35 años se asoció, significativamente, con el desinterés para recoger los reportes (RM = 0.021; IC95%: 0.35-0.92; p = 0.021). El carecer de estudios o solo haber cursado el nivel primario se asociaron con el desinterés para recoger los reportes de la prueba de Papanicolaou (RM = 2.83; IC95%: 1.30-6.15; p = 0.007); no haber oído hablar del virus del papiloma humano (VPH) (RM = 2.56; IC95%: 1.17-5.60; p = 0.016) y tener dificultad por el horario de trabajo (RM = 2.01; IC95%: 1.23-3.27; p = 0.005). CONCLUSIONES: Las barreras personales, como un escaso grado de instrucción, la falta de conocimiento del virus del papiloma humano y las dificultades relacionadas con el horario de trabajo, aumentaron la probabilidad de no acudir a recibir el informe de la prueba.

Abstract OBJECTIVE: To identify the personal, cultural and institutional barriers associated with patients' lack of interest in knowing (obtaining) the report of the Papanicolaou test. MATERIALS AND METHODS: Observational, analytical, case-control study carried out in the Moyopampa Health Center, district of Lurigancho-Chosica, in Lima-Peru, during December 2022. The sample consisted of cases (patients who did not obtain the report of the last Papanicolaou test performed in the last two years) and controls (patients who came to obtain their report). Study parameters: personal, cultural and institutional barriers recorded in a previously validated questionnaire. The association between variables was estimated with Pearson's χ² and Fisher's exact test, odds ratio with 95% confidence interval and p < 0.05. RESULTS: 138 cases and 138 controls were examined. Regarding personal barriers, age 25-35 years was significantly associated with disinterest in reporting (MR = 0.021; 95%CI: 0.35-0.92; p = 0.021). Lack of education or having attended only primary school was associated with disinterest in collecting Pap smear reports (MR = 2.83; 95%CI: 1.30-6.15; p = 0.007); not having heard of the Pap smear was associated with disinterest in collecting Pap smear reports (MR = 2.83; 95%CI: 1.30-6.15; p = 0.007); not having heard of the Pap smear was associated with disinterest in collecting Pap smear reports (MR = 2.83; 95%CI: 1.30-6.15; p = 0.007). 007); not having heard of human papillomavirus (HPV) (MR = 2.56; 95%CI: 1.17-5.60; p = 0.016); and having difficulty because of work schedule (MR = 2.01; 95%CI: 1.23-3.27; p = 0.005). CONCLUSIONS: Personal barriers, such as low educational level, lack of knowledge about human papillomavirus, and difficulties related to work schedule, increased the likelihood of not attending to receive the test report.

Underestimated Cervical Cancer among Women over 65 Years Old: Is It Time to Revise the Screening Target Age Group? / Câncer cervical subestimado entre mulheres com mais de 65 anos: É hora de rever a faixa etária alvo do rastreamento?

Abstract Objective To compare cytological and histological results from women > 64 years old who followed the Brazilian national cervical cancer screening guidelines with those who did not. Methods The present observational retrospective study analyzed 207 abnormal cervical smear results from women > 64 years old in a mid-sized city in Brazil over 14 years. All results were reported according to the Bethesda System. The women were divided into those who followed the screening guidelines and those who did not. Results Atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion cytology results were found in 128 (62.2%) cases. Of these, 112 (87.5%) had repeated cytology with positive results. The other 79 (38.1%) with abnormal results should have been referred to colposcopy and biopsy. Out of 41 (51.9%) biopsied women, 23 (29.1%) had a confirmed diagnosis of neoplasia or precursor lesion. In contrast, among the 78 (37.7%) biopsied patients, 40 (51.3%) followed the guideline recommendations, with 9 (22.5%) positive biopsies. Of the 38 (48.7%) women who did not follow the guidelines, there were 24 (63.1%) positive results. Women who did not follow the guidelines demonstrated higher chances of cancer and precursor lesions (odds ratio [OR]: 5.904; 95% confidence interval [CI]: 2.188-15.932; p = 0.0002). Conclusion Women > 64 years old who did not follow the national screening protocol showed significant differences in the frequency of abnormal results and severity of diagnosis compared with those who followed the protocol.

Conclusão Mulheres > 64 anos que não seguiram a diretriz nacional de rastreamento apresentaram diferenças significativas na frequência de resultados anormais e gravidade do diagnóstico em comparação com aquelas que seguiram a diretriz.

Predictors of non-adherence to cervical cancer screening among immigrant women in Ontario, Canada.

Cervical cancer is one of the most common types of cancer among women and is largely preventable with regular screening using Papanicolau (Pap) tests. In Canada, all provinces have regular screening programs, although with slightly differing recommendations. Previous research has found that immigrant women, who are a large proportion of the Canadian population, are at higher risk of being under-screened, or non-adherent to the recommended screening frequency. Using data from the 2017 Canadian Community Health Survey, this study examined: (1) the extent to which immigration status and time since immigration are associated with Pap test adherence in Ontario, and (2) predictors of Pap test adherence for immigrants and Canadian born populations in Ontario, Canada's most populous province, with a focus on the role of racial or ethnic identity among immigrants. Estimates of 3-year test adherence were 71.3 % (95 %CI: 66.9-75.7) among immigrant women and 75.4 % (95 %CI: 73.1-77.1) among non-immigrant women. Recent immigrants (6-10 years in Canada) had lower adherence (63.5 %, 95 %CI: 48.0-80.0). Logistic regression models found that immigrant women had lower adherence than Canadian-born women, controlling for age, household income, education, and having a primary care physician. Subgroup analysis found that South Asian immigrant women were least likely to be adherent. These results support targeted programming to increase screening adherence among recent immigrants and raise concerns regarding potential barriers to screening. Data that allow better disaggregation of racial and ethnic identities are important for better understanding the potential implications of these patterns for racial inequities in health.

Acesso e utilização da atenção ginecológica na atenção primária a saúde: percepção do homem transexual / Access and use of gynecological care in primary health care: perception of transgender men

Investigar a percepção do homem transexual sobre acesso e utilização da atenção ginecológica em serviços da Atenção Primária à Saúde no SUS. Estudo qualitativo e descritivo. A população foi de cinco participantes; todos homens trans, residentes em municípios do estado de Minas Gerais, Brasil. A coleta de dados foi realizada por meio de entrevistas virtuais, entre o final de 2021 e início de 2022. Para análise dos dados obtidos, a técnica de Bardin foi utilizada. O desrespeito e o despreparo dos profissionais de saúde no atendimento foram indicados em todas as entrevistas, dificultando o acesso à saúde da população LGBTQIAP+. Baixa procura da população trans pelo serviço de saúde por receio e medo de (re)viver experiências traumatizantes indica que o enfermeiro de serviços de Atenção Primária à Saúde necessita desenvolver conhecimento e habilidades para acolher a população transexual, a fim de garantir humanização do atendimento.

To investigate the perception of transgender men of access and use of gynecological care in Primary Health Care services in SUS. A qualitative, descriptive study. A population of five participants, all transgender men, living in cities of the state of Minas Gerais, Brazil. Data collection occurred via online interviews between late 2021 and early 2022. To analyze data, the Bardin technique was used. The lack of respect and preparation of health professionals in service were mentioned in all interviews. This hindered access of the LGBTQIAP+ population. Low demand from the transgender population for health services due to dread and fear of (re)experiencing traumatizing situations suggests that the Primary Health Care services professional must build knowledge and skills to welcome the transgender population in order to guarantee humanized services.

Use of grape-based stain (Vinatela) on cervical cytology: A Peruvian validation study.

Objectives: The Papanicolaou's (Pap's) stain is used for cervical cancer screening. It employs toxic-carcinogenic expensive reagents, which may not be easily accessible to many communities worldwide. The objective of this study was to validate the grape-based alcohol-extracted dye (Vinatela) on normal cervical samples for the Pap test. Material and Methods: Samples of the two grape species were collected from two vineyards through the Agroindustrial Research Institute of Universidad Privada San Juan Bautista. The dye extraction from the grape species and the dye performance to stain cells were conducted in three phases: (a) direct staining with pre-fermentation wine products, (b) direct fragmentation of grapes and direct staining with shells of the grapes, and (c) alcoholic extraction of the dye. Vinatela obtained from two species (Vitis vinifera "Tempranillo" and "Malbec") and posterior staining of cervical samples. We conducted a double-blind validation on 30 cervical samples. Results: The basophilic components of the cervical cells were stained. Alcoholic extraction staining protocol had a low yield. The nuclear and cytoplasmic borders, the nuclear details, and the polymorphonuclear nuclei were stained with Vinatela and could be differentiated during nuclear coloration. The initial staining protocol was 10- 20 min × (mean ~12 min) staining time. We noted a slightly better staining with V. v. Tempranillo as compared to V. v. Malbec (P = 0.045). Conclusion: Cervical cells stained with Vinatela stain from two grape species cultivated in the Southern of Peru, showed basophilic nuclear details.

Usefulness of the human papillomavirus DNA chip test as a complementary method for cervical cytology.

Objectives: As a convenient and economical method of screening cervical cancer and precancerous pathologies, the Papanicolaou smear (Pap smear) has been most widely used. Nevertheless, it requires cytological changes for making diagnoses and reportedly has a high false-negative rate. In this study, the usefulness of the human papillomavirus (HPV) DNA chip test as a complementary method that can compensate for the defect of the Pap smear was investigated. Material and Methods: Of the 6516 patients who simultaneously underwent a Pap smear and an HPV DNA chip test at Chonnam National University Hospital between January 2015 and December 2016, 1897, an initial PAP smear-negative patients who had undergone an additional Pap smear during their 2-year follow-up period were selected for this study. Of the subject patients, 281 underwent a cervical biopsy. Results: The Pap smear follow-up of an initial Pap smear-negative subjects showed 53 (75.7%) HPV high-risk positive cases in the cytology low-grade lesion group (70 cases) and 46 (97.8%) HPV high-risk positive cases in the cytology high-grade lesion group (47 cases). The 281 biopsy cases included 67 biopsy low-grade lesion cases and 74 biopsy high-grade lesion cases, of which there were 45 (67.2%) and 67 (90.5%) HPV high-risk positive cases, respectively. The follow-up cytology on the high-risk HPV-positive subjects showed that the ratio of their high-grade lesions was 260.8 times greater than that of the high-risk HPV-negative subjects (OR = 260.8 and 95% CI: 36.1 and 1886.1); and their biopsy showed that the ratio of their high-grade lesions was 102.7 times greater than that of the HPV-negative subjects (OR = 102.7 and 95% CI: 14.0 and 753.3). Conclusion: The complementary use of the HPV DNA chip test may be useful in increasing the accuracy of screening examinations for the early diagnosis of uterine cervix cancer when combined with the Pap smear.

The impact of transformation zone representation on the frequency of abnormal cervical cytological results.

OBJECTIVE: To compare the frequency of abnormal cervical cytological results with and without representation of the transformation zone (TZ) in a medium-sized city in Brazil according to the Bethesda categorization. METHODS: We performed an analytical observational study evaluating cytological results over 15 years from conventional smears collected within the Public Brazilian Health System in Araçatuba, Brazil. Tests were stratified by age and cytological result according to Brazilian guidelines and the Bethesda System. RESULTS: There were 261,881 examinations, 159,251 with and 102,630 without TZ representation. The global frequency of abnormal results was higher in smears with TZ representation (crude odds ratio [OR] 4.03; 95% confidence interval [CI] [3.71-4.38]). Considering only women between 25 and 64 years (the target of the national guidelines), there were higher results for high-grade squamous intraepithelial lesions (OR 11.54; 95% CI 6.74-19.78), low-grade squamous intraepithelial lesions (OR 2.82; 95% CI 2.17-3.67) atypical squamous cell in which high-grade intraepithelial lesion cannot be excluded (OR 6.90; 95% CI 4.91-9.66) and atypical squamous cell of undetermined significance (OR 3.53; 95% CI 3.11-4.01) among cases with TZ representation. CONCLUSION: Samples with TZ representation were associated with higher rates of abnormal results. Health professionals should be regularly trained to understand the weakness of cytological examinations when the TZ is not represented, especially in developing countries.

Prevalence and factors associated with cervical cancer preventive screening in a Peruvian region. / Prevalencia y factores asociados al tamizaje preventivo del cáncer cervical en una región de Perú.

Introduction: Preventive screening for cervical cancer is the best available strategy to reduce the incidence and mortality from this neoplasm. However, the low proportion of women who undergo routine screening is a pending concern for healthcare systems worldwide. Objective: To estimate the prevalence and factors associated with preventive cervical cancer screening in a Peruvian region. Methods: Cross-sectional, multicenter study. It enrolled 1146 women users of healthcare centers in a Peruvian sanitary region. The dependent variable was the performance of cervical cancer preventive screening with Papanicolaou or visual inspection with acetic acid in the last two years. The independent variables were sociodemographic and socio-sanitary factors, knowledge about cervical cancer and human papillomavirus, attitudes and information towards screening tests. To evaluate the association between the variables, crude and adjusted prevalence ratios were calculated with generalized linear models of Poisson. Results: The overall prevalence of preventive screening was 50.5%. This was associated with being tested, having a higher education level and urban area of residence, using contraceptive methods, having health insurance, being recommended by healthcare personnel to be screened, and being concerned about developing cervical cancer. It was also associated with responding that this cancer is preventable, being aware of cervical cancer or human papillomavirus, and believing it can cause cervical cancer. In contrast, considering preventive screening risky was associated with not having the test. Conclusions: The proportion of women with preventive cervical cancer screening is low. In addition, certain associated modifiable factors were identified, which could improve preventive screening behaviors and rates.

Introducción: El tamizaje preventivo del cáncer cervical es la mejor estrategia disponible para mermar la incidencia y mortalidad por esta neoplasia. No obstante, la baja proporción de mujeres que se someten al tamizaje de rutina, constituye un problema pendiente para los sistemas de salud del mundo. Objetivo: Estimar la prevalencia y los factores asociados a realizarse el tamizaje preventivo del cáncer cervical en una región de Perú. Métodos: Estudio transversal y multicéntrico. En él participaron 1146 mujeres usuarias de centros de salud de una región sanitaria de Perú. La variable dependiente fue la realización de un tamizaje preventivo de cáncer cervical con Papanicolaou o inspección visual con ácido acético, en los últimos dos años. Las variables independientes fueron factores sociodemográficos, sociosanitarios, conocimientos sobre cáncer de cuello uterino y virus del papiloma humano, actitudes e información ante las pruebas de tamizaje. Para evaluar la asociación entre las variables se calcularon razones de prevalencia crudas y ajustadas, con modelos lineales generalizados de la familia Poisson. Resultados: La prevalencia general del tamizaje preventivo fue de 50,5%. Esta se asoció a realizarse la prueba, el grado de instrucción superior y área de residencia urbana, usar métodos anticonceptivos, tener seguro de salud, recibir recomendación del personal de salud para realizarse el tamizaje y sentirse preocupada por adquirir cáncer de cuello uterino. También se vinculó a quienes respondieron que el cáncer es prevenible, que habían oído hablar de cáncer cervicouterino o virus del papiloma humano y si cree que este virus puede causar cáncer de cuello uterino, Además, se asoció el admitir que existe posibilidad de curar el cáncer con su detección temprana. En cambio, el considerar riesgoso el tamizaje preventivo se relacionó con no realizarse la prueba. Conclusiones: La proporción de mujeres con tamizaje preventivo de cáncer cervical es baja. Asimismo, se identificaron ciertos factores asociados modificables, los que podrían mejorar las conductas y tasas del tamizaje preventivo.
