This study aimed to investigate the optimal conditions for Papanicolaou (Pap) smear to increase the success rate of target cell isolation through manual microdissection (MMD) and prevent cell spread. Pap smears were prepared using an HPV42-positive SurePath™ liquid-based cytology case, and 46 and 50 koilocytes were used in wet and dried Pap smears, respectively, to verify the success rate of target cell isolation using MMD based on the HPV detection rate. During MMD, the microscopic examination of both specimens revealed that cells in dried smears could be easily identified; however, cell debris remained in the surrounding area after MMD. Although it was difficult to observe cells in wet smears, there was no cell debris. When the needle tip was immersed in DNA lysate after cell isolation through MMD, a difference in cell solubility was found between dry and wet smears. HPV42 was detected in 94.7% and 97.4% of dried and wet Pap smears, respectively, via polymerase chain reaction genotyping using lysed cell solution; the detection rates were not significantly different. The isolation of target cells from wet Pap smears using MMD reduced the risk of contamination and increased the success rate of HPV detection. This study might facilitate the identification of new CIN-derived HPV-infected cells using MMD with wet Pap smears.

INTRODUCTION
Cervical cancer remains a reproductive health burden. Pap smear (PS) screening can detect cervical cancer early but is underused despite being subsidized. Motivational factors play a role in promoting PS screening. This study aimed to determine the women's motivation toward PS screening based on Protection Motivation Theory (PMT), which mainly focused on sexual and screening status.
MATERIALS AND METHODS
The study was conducted electronically throughout Malaysia from January to February 2022 by disseminating Google Form (https://forms.gle/cD7fkUKYR4Cq6kZC8) via multiple WhatsApp groups to reach 526 women aged 21-65 years. The questionnaire consists of 24 items based on seven PMT constructs [perceived vulnerability, perceived severity, self-efficacy, response efficacy, fear (threat appraisal), response costs (coping appraisal), and protection motivation]. The descriptive statistics and independent -test was used to analyze data using IBM SPSS Statistics software, version 25.
RESULTS
Most respondents were sexually active [80.6% ( = 424)] and have heard of PS screening [95.8% ( = 504)]. More than half of respondents did not have PS screening in the last three years [59.3% ( = 312)]. Sexually active women have heard and have undergone PS screening feel less threatened with low coping appraisals. Undergoing PS screening made women perceived more response efficacy ( =. 011), more self-efficacy ( <. 001), and higher protection motivation ( <. 001) toward PS screening.
CONCLUSIONS
Women's motivation related to PS screening needs to be highlighted. Future development of health education strategy should include motivation focused in emphasizing the threat and coping appraisal into educational plan to ensure women come forward for screening.

BACKGROUND
In 2020, cervical cancer ranked fourth in terms of both frequency of diagnosis and the leading cause of cancer-related deaths among women globally. Among Malaysian women, it was the third most prevalent form of cancer. Published data on nationally representative cervical cancer screening in Malaysia have been limited. Therefore, this study aimed to determine the prevalence of receiving a Pap smear test in the past three years, its relationship with socio-demographic factors and physical activity.
METHODS
Using a subset of survey data from the National Health and Morbidity Survey (NHMS) 2019, a secondary data analysis was performed. Trained research assistants collected data through face-to-face method using a mobile tablet questionnaire system application. Logistic regression analysis was performed to examine the relationship between sociodemographic factors, physical activity, and cervical cancer screening. The analyses were conducted using STATA version 14 (Stata Corp, College Station, Texas, USA), accounting for sample weighs and complex sampling design.
RESULTS
The analysis included 5,650 female respondents, representing an estimated 10.3 million Malaysian female adults aged 18 and above. Overall, 35.2% (95%CI 33.2, 37.4) respondents had a Pap smear test within the past three years. Respondents who were physically active were 1.41 times more likely to have a Pap smear test. Similarly, respondents aged 35-59 (OR 1.84; 95%CI 1.46, 2.34) and those living in rural localities (OR 1.38; 95%CI 1.13, 1.70) had higher odds of receiving a Pap smear test. Compared to married respondents, single respondents (OR 0.04; 95%CI 0.02, 0.07) and widowed/divorcee respondents (OR 0.72; 95%CI 0.56, 0.82) were less likely to receive a Pap smear test. Educated respondents were more likely to have had a Pap smear test.
CONCLUSIONS
The overall prevalence of cervical cancer screening in Malaysia remains low (35.2%). Efforts should be made to strengthen health promotion programs and policies in increasing awareness on the significance of cervical cancer screening. These initiatives should specifically target younger women, single women, and widowed/divorced individuals. The higher cervical screening uptake among rural women should be studied further, and the enabling factors in the rural setup should be emulated in urban areas whenever possible.

Late diagnosis and the lack of screening methods for early detection define high-grade serous ovarian cancer (HGSOC) as the gynecological malignancy with the highest mortality rate. In the work presented here, we investigated a retrospective and multicentric cohort of 250 archival Papanicolaou (Pap) test smears collected during routine gynecological screening. Samples were taken at different time points (from 1 month to 13.5 years before diagnosis) from 113 presymptomatic women who were subsequently diagnosed with HGSOC (pre-HGSOC) and from 77 healthy women. Genome instability was detected through low-pass whole-genome sequencing of DNA derived from Pap test samples in terms of copy number profile abnormality (CPA). CPA values of DNA extracted from Pap test samples from pre-HGSOC women were substantially higher than those in samples from healthy women. Consistently with the longitudinal analysis of clonal pathogenic mutations, this assay could detect HGSOC presence up to 9 years before diagnosis. This finding confirms the continual shedding of tumor cells from fimbriae toward the endocervical canal, suggesting a new path for the early diagnosis of HGSOC. We integrated the CPA score into the EVA (early ovarian cancer) test, the sensitivity of which was 75% (95% CI, 64.97 to 85.79), the specificity 96% (95% CI, 88.35 to 100.00), and the accuracy 81%. This proof-of-principle study indicates that the early diagnosis of HGSOC is feasible through the analysis of genomic alterations in DNA from endocervical smears.

BACKGROUND
The Fine needle aspiration cytology (FNAC) is considered as a valuable and distinguished diagnostic test in the initial assessment of the patients presenting with a mass in the head and neck region or when a recurrence is suspected after previous treatment.
AIMS
This study was therefore designed to elucidate the efficacy of FNAC as an alternate diagnostic tool to histopathology in head and neck swellings and evaluation of staining efficacy of PAP and MGG stain over Haematoxylin and eosin (H and E) in routine cytopathological smears.
SETTINGS AND DESIGN
The study was conducted in the Department of Oral and Maxillofacial Pathology, where FNAC samples were collected from 150 patients with head and neck swellings.
MATERIALS AND METHODS
All the slides were stained with H and E, Papanicolaou (PAP), and May Grunewald Giemsa (MGG) stains. The cytopathological diagnosis was compared with histopathological diagnosis based on H and E stained sections obtained from paraffin-embedded formalin-fixed biopsy specimen of benign and malignant neoplasms.
STATISTICAL ANALYSIS USED
The resulting data were analyzed using SPSS software version 19. Differences between the variables were analyzed using Pearson Chi-square test and Kruskal-Wallis test wherever applicable.
RESULTS
The FNAC as a diagnostic tool has sensitivity of 84.8%, 72.72%, and 78.78%, specificity of 62.5%, 75%, and 75%, and accuracy of 80.48%, 73.14%, and 78.04% in H and E, MGG, and PAP stain, respectively. PAP stain was the most efficient stain when all qualitative parameters are taken into consideration with maximum sensitivity and specificity for achieving definitive cytodiagnosis.
CONCLUSIONS
The FNAC is an inexpensive and minimally invasive technique to diagnose different types of head and neck swellings and complement histopathological diagnosis.

JAMA Network Open Nov 2023Breast, cervical, and colorectal cancer-screening disparities existed prior to the COVID-19 pandemic, and it is unclear whether those have changed since the pandemic.
IMPORTANCE
Breast, cervical, and colorectal cancer-screening disparities existed prior to the COVID-19 pandemic, and it is unclear whether those have changed since the pandemic.
OBJECTIVE
To assess whether changes in screening from before the pandemic to after the pandemic varied for immigrants and for people with limited income.
DESIGN, SETTING, AND PARTICIPANTS
This population-based, cross-sectional study, using data from March 31, 2019, and March 31, 2022, included adults in Ontario, Canada, the country's most populous province, with more than 14 million people, almost 30% of whom are immigrants. At both dates, the screening-eligible population for each cancer type was assessed.
EXPOSURES
Neighborhood income quintile, immigrant status, and primary care model type.
MAIN OUTCOMES AND MEASURES
For each cancer screening type, the main outcome was whether the screening-eligible population was up to date on screening (a binary outcome) on March 31, 2019, and March 31, 2022. Up to date on screening was defined as having had a mammogram in the previous 2 years, a Papanicolaou test in the previous 3 years, and a fecal test in the previous 2 years or a flexible sigmoidoscopy or colonoscopy in the previous 10 years.
RESULTS
The overall cohort on March 31, 2019, included 1 666 943 women (100%) eligible for breast screening (mean [SD] age, 59.9 [5.1] years), 3 918 225 women (100%) eligible for cervical screening (mean [SD] age, 45.5 [13.2] years), and 3 886 345 people eligible for colorectal screening (51.4% female; mean [SD] age, 61.8 [6.4] years). The proportion of people up to date on screening in Ontario decreased for breast, cervical, and colorectal cancers, with the largest decrease for breast screening (from 61.1% before the pandemic to 51.7% [difference, -9.4 percentage points]) and the smallest decrease for colorectal screening (from 65.9% to 62.0% [difference, -3.9 percentage points]). Preexisting disparities in screening for people living in low-income neighborhoods and for immigrants widened for breast screening and colorectal screening. For breast screening, compared with income quintile 5 (highest), the β estimate for income quintile 1 (lowest) was -1.16 (95% CI, -1.56 to -0.77); for immigrant vs nonimmigrant, the β estimate was -1.51 (95% CI, -1.84 to -1.18). For colorectal screening, compared with income quintile 5, the β estimate for quntile 1 was -1.29 (95% CI, 16 -1.53 to -1.06); for immigrant vs nonimmigrant, the β estimate was -1.41 (95% CI, -1.61 to -1.21). The lowest screening rates both before and after the COVID-19 pandemic were for people who had no identifiable family physician (eg, moving from 11.3% in 2019 to 9.6% in 2022 up to date for breast cancer). In addition, patients of interprofessional, team-based primary care models had significantly smaller reductions in β estimates for breast (2.14 [95% CI, 1.79 to 2.49]), cervical (1.72 [95% CI, 1.46 to 1.98]), and colorectal (2.15 [95% CI, 1.95 to 2.36]) postpandemic screening and higher uptake of screening in general compared with patients of other primary care models.
CONCLUSIONS AND RELEVANCE
In this cross-sectional study in Ontario that included 2 time points, widening disparities before compared with after the COVID-19 pandemic were found for breast cancer and colorectal cancer screening based on income and immigrant status, but smaller declines in disparities were found among patients of interprofessional, team-based primary care models than among their counterparts. Policy makers should investigate the value of prioritizing and investing in improving access to team-based primary care for people who are immigrants and/or with limited income.

AIM
The present study aimed to investigate healthcare professionals' perceptions and experiences in caring for cervical cancer patients. The present study was also designed to assess the healthcare professionals' attitudes toward cervical cancer screening and its prevention.
METHODS
A cross-sectional quantitative descriptive study was conducted, and 540 participants (240 nurses and 300 doctors), from different hospitals of Pakistan have been selected and interviewed.
RESULTS
Data was collected using structured questionnaires and SPSS was used to statistically analyze the data. Participants in the present study are questioned with respect to age, gender, and work experience. The mean age of the participants is 35 years. Among them, 41% of participants are < 35 years of age and 59% are > 35 years of age. In the case of gender, 22% of participants are males and 78% are females. 47% of the participants have work experience < 20 years and 53% have work experience > 20 years. Data from the present study showed that most of the nurses are less educated (basic education of middle and matric degree) with a simple diploma in nursing and midwifery. Nurses and doctors do not have any knowledge/experience of the patient's psychological counselling. Participants are also questioned with respect to HPV vaccination, 39% of nurses and 62% of doctors are vaccinated. The difference in vaccination frequency of participants was observed as statistically significant (p < 0.0001). In the case of treatment modalities, doctors have statistically more knowledge about the pap smear (p < 0.0001), cervical biopsy (p < 0.0001), colposcopy (p < 0.0001), and visual application after acetic acid application (p < 0.0001) compared to nurses. Data analysis showed that Pap smear was performed significantly higher in married females compared to unmarried (p < 0.0001).
CONCLUSION
our study provides a comprehensive and in-depth perspective of the nurses and doctors for cervical cancer patients. Cervical cancer prevalence is increasing due to inadequate knowledge and awareness among healthcare professionals. Improvement can be brought about by the regular use of treatment modalities in unmarried females also.

BACKGROUND
The incidence of cervical cancer has decreased by 70% since the 1950s. Preventative measures include vaccination against HPV strains and Papanicolaou tests. Early identification of cervical cancer through routine screening can significantly improve patient outcomes.
MATERIALS AND METHODS
At our academic institution, Community Internal Medicine (CIM) Clinic, 63% of female patients aged 21-65 were compliant with cervical cancer screening. The opening of the 'Saturday Pap Smear Clinic' sought to address barriers by offering non-traditional appointment times on Saturday mornings with an all female staff. Our aim was to increase the cervical cancer screening rate by 1% within 12 weeks. Our team compared CIM (intervention) and family medicine (FM) (control) compliance rates from September 2021 to January 2022. Messages were sent to the patient indicating non-compliance and offering options to complete screening.
RESULTS
At the start of this study, 5239 CIM patients were cervical cancer screening non-compliant. Postintervention, cervical screening rates among non-compliant women within CIM improved by 1.2%. The intervention cohort, CIM patients, had a significant improvement in compliance compared with the control group, FM patients. White women between the ages of 50 and 65 comprised the majority of patients who used the 'Saturday Pap Smear Clinic'.
CONCLUSIONS
The availability of Saturday appointments for cervical cancer screening completion can enhance cervical cancer screening compliance among eligible women. Eliminating barriers for women can improve health outcomes.

Review
BACKGROUND
Widespread use of screening in high-income countries has led to significant reductions in mortality from cervical cancer. However, in Iran, the main reason for the late diagnosis of cervical cancer was the failure to perform a Pap smear (Papanicolaou). We aimed to investigate the status of cervical cancer prevention and its challenges and solutions in Iran.
METHOD
We conducted a systematic review of literature published from 1974 to 2021 in the electronic databases, including PubMed, Web of Science, Embase, Scopus, and Google Scholar, and retrieved all English-language articles. Following the application of the inclusion and exclusion criteria, full-text articles were identified and evaluated for eligibility. Finally, these publications were analyzed as part of the synthesis.
RESULTS
Lower social-economic level, inadequate knowledge of screening tests and health centers for Pap test performance leading to worse outcomes such as lower screening participation or coverage.
CONCLUSION
By addressing these challenges through increasing education, increasing service accessibility, expanding screening programs, improving public awareness, improving insurance coverage, and establishing a control protocol for follow-up, it is possible to reduce cervical cancer incidence and mortality.
