[Effect of COVID-19 pandemics in treatment of cervical cancer: pre/post study]

INTRODUCTION

Little evidence exists on the impact of the COVID-19 pandemics on the compliance with cervical cancer treatment.

METHODS

We carried out a population-based, before-and-after retrospective cohort study of all cervical cancer patients diagnosed in the Jujuy province public health sector (n=140), Argentina, between 2017 and 2020. Patients diagnosed in 2020 were considered exposed to the COVID-19 pandemic (n=21). We used multivariable logistic regression to assess the relationship between the pandemics and compliance with treatment. We also measured treatment duration for women who were indicated brachytherapy and time to treatment initiation by stage.

RESULTS

Compared with women diagnosed in 2017-2019 the odds ratio of non-complying with treatment was 1.77 (95%CI 0.59-5.81; p = 0.32) for women diagnosed during 2020. An increased risk of non-compliance was found in patients with prescribed brachytherapy (OR 4.14. 95%CI 1.95-9.11; p < 0.001). Median treatment duration for women with prescribed brachytherapy was 12.8 and 15.7 weeks in 2017-2019 vs. 2020 (p = 0.33); median time to treatment initiation for women with early-stage disease was 9 and 5 weeks during 2017-2019 and 2020 respectively (p = 0.06), vs 7.2 and 9 weeks in 2017-2019 and 2020 respectively (p = 0.36) for patients with stages IIB+ disease.

CONCLUSIONS

Low access to brachytherapy was a major determinant of non-compliance. irrespective of the effect of the pandemics.

Latin America and the Caribbean Code Against Cancer 1st Edition: Medical interventions including hormone replacement therapy and cancer screening

Prostate, breast, colorectal, cervical, and lung cancers are the leading cause of cancer in Latin America and the Caribbean (LAC) accounting for nearly 50% of cancer cases and cancer deaths in the region. Following the IARC Code Against Cancer methodology, a group of Latin American experts evaluated the evidence on several medical interventions to reduce cancer incidence and mortality considering the cancer burden in the region. A recommendation to limit the use of HRT was issued based on the risk associated to develop breast, endometrial, and ovarian cancer and on growing concerns related to the over-the-counter and without prescription sales, which in turn bias estimations on current use in LAC. In alignment with WHO breast and cervical cancer initiatives, biennial screening by clinical breast examination (performed by trained health professionals) from the age of 40 years and biennial screening by mammography from the age of 50 years to 74, as well as cervical screening by HPV testing (either self-sampling or provider-sampling) every 5-10 years for women aged 30-64 years, were recommended. The steadily increasing rates of colorectal cancer in LAC also led to recommend colorectal screening by occult blood testing every two years or by endoscopic examination of the colorectum every 10 years for both men and women aged 50-74 years. After evaluating the evidence, the experts decided not to issue recommendations for prostate and lung cancer screening; while there was insufficient evidence on prostate cancer mortality reduction by prostate-specific antigen (PSA) testing, there was evidence of mortality reduction by low-dose computed tomography (LDCT) targeting high-risk individuals (mainly heavy and/or long-term smokers) but not individuals with average risk to whom recommendations of this Code are directed. Finally, the group of experts adapted the gathered evidence to develop a competency-based online microlearning program for building cancer prevention capacity of primary care health professionals.

Photoelectron Spectroscopy of Oppositely Charged Molecular Switches in the Aqueous Phase: Theory and Experiment

XUV photoelectron spectroscopy (XPS) is a powerful method for investigating the electronic structures of molecules. However, the correct interpretation of results in the condensed phase requires theoretical models that account for solvation. Here we present experimental aqueous-phase XPS of two organic biomimetic molecular switches, NAIP and p-HDIOP. These switches are structurally similar, but have opposite charges and thus present a stringent benchmark for solvation models which need to reproduce the observed ΔeBE = 1.1 eV difference in electron binding energy compared to the 8 eV difference predicted in the gas phase. We present calculations using implicit and explicit solvent models. The latter employs the average solvent electrostatic configuration and free energy gradient (ASEC-FEG) approach. Both nonequilibrium polarizable continuum models and ASEC-FEG calculations give vertical binding energies in good agreement with the experiment for three different computational protocols. Counterions, explicitly accounted for in ASEC-FEG, contribute to the stabilization of molecular states and reduction of ΔeBE upon solvation.

Implementation of an mHealth intervention to increase adherence to triage among HPV positive women with HPV-self-collection (ATICA study): post-implementation evaluation from the women's perspective

BACKGROUND

Low adherence to triage after positive screening is a widespread problem for cervical cancer screening programs in Low- and Middle-income Countries. Adherence to cytology-based triage can be challenging, especially among women with self-collected tests. SMS-based interventions are accepted by women and can increase screening uptake. The ATICA study was an effectiveness-implementation hybrid type I trial, combining a cluster randomized controlled trial (RCT) with a mixed-methods implementation evaluation involving quantitative and qualitative methods. Although the RCT provided evidence regarding the effectiveness of the SMS-based intervention, less is known about its acceptability, relevance, and usefulness from the women´s perspective.

METHODS

We carried out a cross-sectional study based on a structured questionnaire among HPV-positive women who were enrolled in ATICA's intervention group. We measured acceptability, appropriateness, and message content comprehension. Also, we evaluated if the SMS message was considered a cue to encourage women to pick up their HPV test results and promote the triage.

RESULTS

We interviewed 370 HPV-positive women. Acceptability of SMS messages among women who had received at least one message was high (97%). We found high levels of agreement in all appropriateness dimensions. More than 77% of women showed high comprehension of the content. Among women who received at least one SMS message, 76% went to the health center to pick up their results. Among those who got their results, 90% reported that the SMS message had influenced them to go. We found no significant differences in acceptability, appropriateness or message comprehension between women who adhered to triage and those who did not adhere after receiving the SMS messages.

CONCLUSION

The intervention was highly acceptable, and women reported SMS was an appropriate channel to be informed about HPV test results availability. SMS was also a useful cue to go to the health center to pick up results. The implementation did not encounter barriers associated with the SMS message itself, suggesting the existence of other obstacles to triage adherence. Our results support the RCT findings that scaling up SMS is a highly acceptable intervention to promote cervical screening triage adherence.

Implementation and scaling-up of an effective mHealth intervention to increase adherence to triage of HPV-positive women (ATICA study): perceptions of health decision-makers and health-care providers

BACKGROUND

The ATICA study was a Hybrid I type randomized effectiveness-implementation trial that demonstrated effectiveness of a multicomponent mHealth intervention (Up to four SMS messages sent to HPV-positive women, and one SMS message to CHWs to prompt a visit of women with no triage Pap 60 days after a positive-test), to increase adherence to triage of HPV positive women (ATICA Study). We report data on perceptions of health decision-makers and health-care providers regarding the intervention implementation and scaling-up.

METHODS

A qualitative study was carried out based on individual, semi-structured interviews with health decision-makers (n = 10) and health-care providers (n = 10). The themes explored were selected and analyzed using domains and constructs of the Consolidated Framework for Implementation Research (CFIR) and the maintenance dimension of the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework.

RESULTS

Both health-care providers and decision-makers had a positive assessment of the intervention through most included constructs: knowledge of the intervention, intervention source, design quality, adaptability, compatibility, access to knowledge and information, relative advantage, women's needs, and relative priority. However, some potential barriers were also identified including: complexity, leadership engagement, external policies, economic cost, women needs and maintenance. Stakeholders conditioned the strategy's sustainability to the political commitment of national and provincial health authorities to prioritize cervical cancer prevention, and to the establishment of the ATICA strategy as a programmatic line of work by health authorities. They also highlighted the need to ensure, above all, that there was staff to take Pap tests and carry out the HPV-lab work, and to guarantee a constant provision of HPV-tests.

CONCLUSION

Health decision-makers and health-care providers had a positive perception regarding implementation of the multicomponent mHealth intervention designed to increase adherence to triage among women with HPV self-collected tests. This increases the potential for a successful scaling-up of the intervention, with great implications not only for Argentina but also for middle and low-income countries considering using mHealth interventions to enhance the cervical screening/follow-up/treatment process.

Assessing the implementation fidelity of HPV self-collection offered by community health workers during home visits (the EMA strategy): a case study in a low-middle-resource setting in Argentina

BACKGROUND

In Argentina, HPV  self-collection offered by community health workers was demonstrated to be effective to improve cervical cancer screening uptake. Based on these findings, the EMA strategy was scaled up in nine Argentinian provinces. However, there is no evidence about the degree of fidelity-in relation to the core components proposed by the National Program on Cervical Cancer Prevention-with which this strategy was implemented in the new jurisdictions. We carried out a fidelity evaluation of the EMA strategy scaling-up aimed at evaluating the level of adherence to the core components of the EMA strategy, and how different moderating factors affected the implementation fidelity.

METHODS

This descriptive study used a multi-method approach involving quantitative and qualitative evaluations of the implementation fidelity using the Conceptual Framework for Implementation Fidelity. Evaluation of the degree of adherence to the core components of the EMA strategy was carried out through the analysis of a self-administered survey of health promoters, observations, and secondary data from the National Screening Information System. The analysis of moderating factors was carried out through analysis of field notes, and semi-structured interviews with key stakeholders.

RESULTS

Our results showed that the core components with highest fidelity were training, sample handling, and transportation. Regarding the offer of HPV self-collection, we found some adaptations such as locations in which health promoters offered HPV self-collection, and fewer pieces of information provided to women during the offer. In the follow-up and treatment core component, we found a reduced adherence to triage and colposcopy. Some contextual factors had a negative impact on implementation fidelity, such as urban insecurity and the reduction in the number of health promoters that offered HPV self-collection. Moderating factors that contributed to achieve high level of fidelity included a well-defined strategy with clear steps to follow, permanent feedback and high level of engagement among implementers.

CONCLUSIONS

Our study shows how the analysis of fidelity and adaptations of HPV self-collection in real-world contexts are key to measure and maximize its effectiveness in low-middle-income settings.

Ten Steps to Design a Counseling App to Reduce the Psychosocial Impact of Human Papillomavirus Testing on the Basis of a User-Centered Design Approach in a Low- and Middle-Income Setting

PURPOSE

This study describes the 10 steps followed to produce the information architecture of a user-centered design (UCD) counseling mobile application, the first phase to develop an app. The app aims to reduce the psychosocial impact of the human papillomavirus test result and improve women's knowledge of human papilloma virus and cervical cancer.

METHODS

We used a UCD approach to produce the information architecture of the app (ie, how to organize contents into features). We analyzed field notes, meeting agendas, and documentation produced during each stage of the design process. We described the goals, methods, and outcomes of each step. We also discussed the critical challenges and the strategies to address them.

RESULTS

The steps are (1) knowledge, attitudes, and beliefs mapping: reanalysis of team's research findings from prior studies; (2) environmental scanning of apps available on the market; (3) stakeholders' point of view: The International Advisory Committee; (4) potential user's profile: building archetypes through the Persona method; (5) women's interviews: user's preferences and experiences; (6) effective features: scoping review to select app's features that address psychosocial impact; (7) the user journey: ideal interaction with the gynecological service and the counseling app; (8) women's focus groups: using Personas and Scenarios to discuss app's mock-up; (9) women's design sessions: prototype test and card-sorting techniques; and (10) team's design session: translating results into visual objects and features.

CONCLUSION

We provide here detailed descriptions of the UCD process of an app for human papillomavirus-tested women for those venturing into the area of mHealth strategies work. Our experience can be used as a guide for future mHealth app development for a low- and middle-income setting.

Formative Research to Design SMS Messages to Increase Breast Cancer Screening Uptake in Argentina

PURPOSE

There is a need for interventions to promote breast cancer screening among high-risk population. This formative research is part of a pragmatic randomized trial being conducted in Santa Fe, Argentina, in which we are evaluating whether SMS messages sent to women aged 50-69 increases breast cancer screening uptake. Here, we describe the formative results used to design the content of the SMS messages to be tested in the trial.

METHODS

We conducted four on-line focus groups with women aged 50+ (n = 14). Participatory techniques were used to debate the advantages and disadvantages of different options for the five structural elements -i.e., greeting, recipient, sender, message's topic, and closing line-of the SMS message. We openly coded the discussions for agreements and preferences regarding the SMS message content.

RESULTS

SMS messages as reminders to increase breast cancer screening were highly accepted. Women argued that the greeting line should provide clear information about the topic of the SMS message (eg, Health information). SMS messages should also include the woman's name, because this inclusion would be an indicator that it was a personal SMS message. Most women considered that the sender of the SMS messages should be a health institution as this would legitimize the content. Regarding the topic of the message, women preferred an imperative tone and they mentioned that the SMS message should include information about how to get a mammogram (eg, “Women aged 50-69 should have a mammogram done every two years. Do you have an appointment? WhatsApp to xxxxx”). The closing line should encourage women to get a mammogram (eg, “Ask for your appointment now! It is important!”).

CONCLUSION

Our findings have some implications for the design of mHealth interventions targeted at improving breast cancer screening. A personalized SMS could be a good way of inviting women, although its content must be carefully designed to provide clear information about how to get a mammogram.

Acceptability, appropriateness and feasibility of the Latin American and Caribbean Code against Cancer: perceptions of decision-makers and health professionals in Argentina

Background

Cancer is an important public health problem. In Latin America and the Caribbean, there were approximately 1,500,000 new cases of cancer and 700,000 deaths due to cancer in 2020. These figures will increase by 78% by 2040 to more than 2.5 million people diagnosed with cancer each year, who will require medical attention, care and support. However, it is estimated that at least 40% of cancers could be prevented by adopting a healthier lifestyle, reducing risky behaviours and implementing recommended health interventions.

Objective

To evaluate the perceptions of health decision-makers and professionals regarding the Latin American and Caribbean Code against Cancer (CLCC) as a support tool for designing and implementing public policies for cancer prevention and control (acceptability, appropriateness and feasibility) in Argentina.

Methods

A qualitative study was conducted using individual, semi-structured interviews with health decision-makers and professionals (n = 30). The questions and thematic analysis of the information gathered have been guided by the principles of the Consolidated Framework for Implementation Research: intervention characteristics, outer setting, inner setting and characteristics of individuals.

Results

Health professionals and health decision-makers broadly accepted the proposal of the CLCC as a tool for supporting the design and implementation of public policies for cancer prevention and control, and considered it to be appropriate. Additionally, from the interviewees' perspective, factors should be ensured to guarantee the implementation of the CLCC as a viable public health policy. They also felt it was right to take the CECC as a model and to adapt its content to the specific characteristics of the Latin American population, customs, lifestyle habits, epidemiological characteristics and, in particular, the Argentinian socio-economic context. Interviewees perceived the CLCC as a health intervention whose complexity varied depending on the recommendation, although most of them were feasible. The broad consensus among the interviewees was that the development of the CLCC could yield numerous advantages in improving cancer prevention and control policy, and responding to the needs of the population. It was also considered to be an opportunity to introduce fundamental changes. With regard to the implementation of the CLCC, interviewees reported a favourable institutional climate, since they perceived that it would receive a priority equal to or greater than the ongoing prevention measures, and that it would have the commitment of the health authorities. They also felt that the implementation of the CLCC in their work environment would not be very complicated, and that the decision-makers and professionals had the necessary capacity to implement it. Finally, they felt that the implementation would be facilitated by the participation and consensus of health decision-makers at the primary care level, and negotiation with industrial and environmental sectors.

Conclusions

Our study shows that health professionals and decision-makers consider the CLCC to be highly acceptable, appropriate and feasible. This would facilitate its implementation as a tool that could enhance current cancer prevention and control policies in Argentina. The results of the study indicate the necessity for the CLCC to be adapted to the socio-economic context of Argentina, and highlight that population adherence to the CLCC recommendations will depend on complex and diverse factors, especially those involving changing unhealthy behaviours linked to cancer risk.

A Counseling Mobile App to Reduce the Psychosocial Impact of Human Papillomavirus Testing: Formative Research Using a User-Centered Design Approach in a Low-Middle-Income Setting in Argentina

Background

Human papillomavirus (HPV) testing detects sexually transmitted infections with oncogenic types of HPV. For many HPV-positive women, this result has negative connotations. It produces anxiety, fear of cancer or death, and disease denial. Face-to-face counseling could present many difficulties in its implementation, but a counseling mobile app could be practical and may help HPV-positive women reduce the psychosocial impact of the result, improve their knowledge of HPV and cervical cancer, and increase adherence to follow-up.

Objective

This study aims to understand HPV-tested women’s perceptions about an app as a tool to receive information and support to reduce the emotional impact of HPV-positive results. We investigated their preferences regarding app design, content, and framing.

Methods

We conducted formative research based on a user-centered design approach. We carried out 29 individual online interviews with HPV-positive women aged 30 years and over and 4 focus groups (FGs) with women through a virtual platform (n=19). We shared a draft of the app's potential screens with a provisional label of the possible content, options menus, draft illustrations, and wording. This allowed us to give women understandable triggers to debate the concepts involved on each screen. The draft content and labels were developed drawing from the health belief model (HBM) and integrative behavioral model (IBM) variables and findings of mobile health literature. We used an FG guide to generate data for the information architecture (ie, how to organize contents into features). We carried out thematic analysis using constructs from the HBM and IBM to identify content preferences and turn them into app features. We used the RQDA package of R software for data processing.

Results

We found that participants required more information regarding the procedures they had received, what HPV-positive means, what the causes of HPV are, and its consequences on their sexuality. The women mentioned fear of the disease and stated they had concerns and misconceptions, such as believing that an HPV-positive result is a synonym for cancer. They accepted the app as a tool to obtain information and to reduce fears related to HPV-positive results. They would use a mobile app under doctor or health authority recommendation. The women did not agree with the draft organization of screens and contents. They believed the app should first offer information about HPV and then provide customized content according to the users’ needs. The app should provide information via videos with experts and testimonies of other HPV-positive women, and they suggested a medical appointment reminder feature. The app should also offer information through illustrations, or infographics, but not pictures or solely text.

Conclusions

Providing information that meets women’s needs and counseling could be a method to reduce fears. A mobile app seems to be an acceptable and suitable tool to help HPV-positive women.

"I'm neither here, which would be bad, nor there, which would be good": the information needs of HPV+ women. A qualitative study based on in-depth interviews and counselling sessions in Jujuy, Argentina

The objective of this qualitative study was to explore the information needs of HPV+ women. We conducted 38 in-depth interviews with HPV+ women in the province of Jujuy, Argentina. The interviews included a counselling session to respond to women’s concerns and questions. Women perceived the information provided as good, despite having several doubts and misconceptions after receiving results of an HPV+ test. They expressed difficulties in formulating questions during the consultation due to shame, excess of information provided or lack of familiarity with technical language. They valued emotional support and being treated kindly by professionals. The perceived information needs that emerged as most important were: (1) the meaning of an HPV+ result and its relationship with cervical cancer evolution and severity; (2) continuity and timing of the care process; (3) information on the sexual transmission of the virus; (4) explanation of the presence or absence of symptoms. Women’s primary unperceived information needs were: (1) detailed information about colposcopy, biopsy and treatments and their effects (including fertility consequences); and (2) deconstructing the association of sexual transmission with infidelity. Sources of information included: (1) the health care system; (2) the internet; and (3) social encounters (close friends and relatives). It is crucial to strengthen the processes for delivering results, with more thorough information, improved emotional support and active listening focused on the patient, as well as to conceive new formats to provide information in stages and/or gradually, in order to facilitate women’s access to the health care system and the information they need.

Abstract 100: Implementation Fidelity of a HPV Self-Collection Strategy in Buenos Aires, Argentina

Purpose: HPV self-collection (SC) has been proposed as a strategy to increase cervical cancer (CC) screening coverage among hard-to-reach women. However, evaluations of the implementation fidelity of this strategy in real-world contexts are scarce. The aim of the study was to evaluate the implementation fidelity of the core components of SC strategy (EMA strategy) in La Matanza, Buenos Aires, Argentina. We report preliminary results.

Methods: We carried out a descriptive study. The core components included: 1) Training: Two workshops delivered to health promoters (HP) including scientific data on CC prevention; 2) Offer of SC during home visits: HP provide women with information about CC prevention, and a 10-minute step-by-step explanation on how to perform SC, 3) Sample handling and transportation (SH&T): Sample collectors labeled with the woman's name and identifying number are transported at room temperature to the HPV laboratory (within 14 days) and 4) Follow-up of HPV+ women: cytology triage for HPV+ women. Data sources included: selfadministered questionnaires to evaluate knowledge acquired in the training (n=171), a structured checklist to evaluate offer of self-collection and SH&T (74 observations), and secondary data from the national screening information system (SITAM) to evaluate follow-up.. Quantitative analyses assessed whether activities were implemented as planned, using descriptive statistics.

Results: Training: 95% of HP participated in the two workshops. More than 90% had adequate knowledge about the strategy (score of more than 70% on questionnaire). Offer of self-collection: 47% offered SC during home visit and 53% in community health meetings and waiting rooms of primary health care centers. HP had less time than stipulated in the training to offer self-collection (mean: 8 minutes; range: 1-17 minutes), so fewer pieces of information were provided. 79% of eligible women accepted self-collection. Sample handling and transportation: More than 96% adhered to the standardized protocol. Follow-up of HPV+ women: 57% of HPV+ women had a triage test registered in SITAM.

Conclusion: The core components with the highest fidelity were Training and SH&T. We found adaptations in the offer of SC. Our results suggest that these adaptations do not affect the acceptability of SC. In addition, adherence to triage in the context of the SC strategy is a challenge.

Abstract 97: Designing a Counseling App to Reduce the Psycho-Social Impact of HPV-Testing: A User-Centered Design Approach

Purpose: HPV-testing detects sexually transmitted infection with oncogenic types of HPV. For many HPV+ women, this result has negative connotations, it produces anxiety, fear of cancer or death, and disease denial. While face-to-face counseling could present many difficulties in its implementation, a counseling mobile-app may help HPV+ women reduce the psychosocial impact of the result, improve their knowledge about HPV and CC and increase adherence to follow-up.

Methods: We conducted formative research based on a user-centered design approach. We carried out 29 individual online interviews with HPV+ women aged 30 and over, and four focus groups (FG) with a total of 19 participants through a virtual platform. We used a focus group guide to produce data for the information architecture (i.e., how to organize contents into features). We carried out thematic analysis using constructs from the Health Belief Model and Integrative Behavioral Model to identify content preferences and turn them into app features. We used the RQDA package of R software for data processing.

Results: Preliminary results showed that participants needed more information regarding the procedures they had received; about what HPV+ means; what are the causes of HPV; if the HPV is present only in females; and if HPV has consequences on their sexuality. Also, we found that women's fear of the disease and death could increase after medical consultations. They had complaints when they had left the consultation with unanswered questions and misconceptions, such as believing that HPV+ is a synonym for cancer. Women accepted the App as a tool to get information and they agreed it can be useful to reduce fears related to HPV-positive results. They would use a mobile-app if the doctor or a health authority recommends it. They believe the app should provide information through videos, illustrations, or infographics, but not by pictures or only text. The app has to offer information on the next steps in the follow-up and medical appointment reminders.

Conclusion: Providing information that meets women's needs and counseling could be a way of reducing fears. A mobile-app seems to be an acceptable and suitable tool to provide support to HPV+ women.

Local and exhaustive study of transmission of detected psychopathological dimensions in family groups in the “albanova” area

Introduction

It is not known with certainty how different phenotypes are transmitted in groups of families divided into three generations.

Objectives

Having meticulously searched for terms of psychopathogic lexicon that best translated the sterile categorical diagnosis, we obtained three dimensional groups for all six families in the three generations.

Methods

We calculated the frequencies and percentages of the three dimensional groups for the three generations of families based on sex.

Results

The chi-square TEST attests a p-value = 0.049, statistically significant for the dimensional group “A”. (Tab. 3)

Conclusions

The genetics, and above all the epigenetics, of the phenotypes are periodically transmitted in group “A” and group “C” in the female and male sex. (Graphs 2.1.1 and 2.3.1) Different phenotypes indicate that the complexity of the interactions of the regulatory mechanisms of genes with the environment is extremely significant for the group with the most severe psychiatric pathology.

Changing the paradigm of cervical cancer prevention through introduction of HPV-testing: evaluation of the implementation process of the Jujuy Demonstration Project in Argentina

Introduction

The Jujuy Demonstration Project (JDP) was a project carried out over the course of 4 years (2011–2014) to develop, implement and evaluate the programmatic components of a Human Papilloma Virus (HPV)-based screening programme in Argentina. The aim of this paper is to present a qualitative evaluation of the context and implementation process of the JDP.

Methods

We used an adaptation of the Health System Framework (HSF), which includes interconnected contextual factors that are considered key drivers for successful health interventions. We reviewed secondary documents, which included scientific reports, norms and regulations, information sheets, power point presentations and manuals and recommendations published by the National Programme for Cervical Cancer Prevention. We also carried out semi-structured interviews with key informants to explore their views about technology acceptability.

Results

Key components of the JDP implementation process were: a high level of political support and consensus among stakeholders, the demonstrated effectiveness of the technology and its acceptability by health authorities and providers, the funding of tests and diagnosis/treatment services, the implementation of an information system for monitoring and evaluation and the reorganisation of the network of screening, diagnosis and treatment services.

Conclusion

This analysis examines the policy context in which the JDP was implemented and the system components that were key for the demonstrated effectiveness of the strategy. Such analyses provide useful insights into core components of HPV testing implementation that are needed to guarantee its potential effectiveness to reduce cervical cancer incidence and mortality.

Adherence to triage among women with HPV-positive self-collection: a study in a middle-low income population in Argentina

Introduction

Screening for cervical cancer (CC) prevention has substantially changed with the introduction of human papillomavirus (HPV) tests. This technology compared to cytology has increased the detection of pre-malignant and malignant cervical lesions in real-world programmes in different settings. Very importantly, through self-collection, HPV testing can reduce barriers to screening and increase coverage. However, when using HPV self-collection, triage tests are a key step in the CC prevention process, and high adherence to triage has been difficult to obtain in low-middle income settings. The aim of this study was to measure adherence to triage among women with HPV+ self-collection and analysed factors associated with this adherence in a middle-low resource setting in Argentina. We also evaluated key indicators related to the implementation of the HPV self-collection strategy.

Methods

We analysed data on screening/triage/diagnosis/treatment from women aged 30+ who performed self-collection between 2015 and 2017 (n = 15,763), in the public health system in Tucuman, Argentina. We analysed secondary data from the national screening information system. The primary outcomes were: 1) adherence to cytology triage within the recommended timeframe (120 days) and 2) overall adherence to cytology triage including data at 18 months after screening. Multivariable regression was used to examine the association between age group, year of the screening test, record of the previous Pap-based screening and health insurance status with adherence to triage test as a primary outcome. We reported odds ratios, 95% confidence intervals and p-value of 0.05, which was considered the threshold for p-values).

Results

We analysed data of 2,389 HPV+ women. The overall adherence to triage at 18 months was 42.9%. The percentage of women completing cytology triage within the recommended timeframe of 120 days was lower (25.2%). Women with the record of a previous Pap-based screening had 1.86 times the odds of having a triage compared to women without a record of a previous Pap-based screening (95% CI: 1.64–2.64, p <0.001). Furthermore, the probability of having triage at the recommended timeframe was higher among women who were older and women with public health insurance.

Conclusions

Our results showed that adherence to triage in the recommended timeframe was low. In addition, the probability of having triage at the recommended timeframe was higher among women with a record of a previous Pap-based screening, a proxy of the use of health services. Our results showed that adherence to triage in the context of the HPV-self-collection strategy is challenging. The implementation of alternative approaches that might facilitate adherence to triage should be further investigated.

Psycho-social impact of positive human papillomavirus testing in Jujuy, Argentina results from the Psycho-Estampa study

Human papillomavirus (HPV) testing can have a negative impact on women's lives which might also result in abandoning the follow-up and treatment process. This study measured the psycho-social impact of HPV-positivity among HPV-tested women from Jujuy, Argentina, a middle-low income setting. In this cross-sectional study (2015-2016), the psycho-social impact of HPV-positivity was measured using the Psycho-Estampa Scale, specifically designed and validated to be used in screening contexts. We measured mean scores for each of the five scale domains, and the Overall Impact score (Values from 1: No impact to 4: Heavy impact). We compared scores according to cytology triage diagnosis using ordinal logistic regression. A total of 163 HPV-positive women were recruited at the Centro Carlos Alvarado hospital and included in the study sample; of these, 124 (76.1%) had normal triage cytologies. The overall Impact score was between low and moderate (mean:2.56, SD:0.65). The highest psycho-social impact was measured in the Worries about cancer and treatment domain (mean score:3.60, SD:0.60), followed by Sexuality domain (mean:2.50; SD:1.00). The Uncertainty about information provided by health providers domain had the lowest mean score (mean:2.14, SD:0.73). Compared to women with normal cytologies (n = 124), women with abnormal cytologies (n = 39) had a higher likelihood of greater overall Psycho-social Impact (OR: 2.91; p = 0.0036). No statistically significant differences were found in scores of specific domains according to cytology results. It is important to devise specific counseling interventions to reduce the psycho-social impact of HPV-Testing as primary screening and its potential effect on completion of the diagnosis/ treatment process.

Developing SMS Content to Promote Papanicolaou Triage Among Women Who Performed HPV Self-collection Test: Qualitative Study

Background

SMS interventions are effective in promoting a variety of health behaviors; however, there is limited information regarding the use of SMS for cervical cancer screening and follow-up care. The Application of Communication and Information Technologies to Self-Collection study aims to evaluate a multicomponent mobile health intervention to increase triage adherence among women with human papillomavirus (HPV)–positive self-collected tests in Jujuy, Argentina. Here, we describe the formative results used to design the content of the SMS to be tested in the trial.

Objective

This study aimed to understand the cultural and contextual elements, women’s beliefs, and perceptions regarding the use of SMS by the health care system and women’s preferences about the message content.

Methods

We conducted five focus groups (FGs), stratified by rural or urban residence and age. All participants were aged 30 years or older and had performed HPV self-collection. Participatory techniques, including brainstorming, card-based classification, and discussions were used to debate the advantages and disadvantages of messages. We openly coded the discussions for agreements and preferences regarding the SMS content. Messages for both HPV-negative and HPV-positive women were validated through interviews with health authorities and 14 HPV-tested women. The final versions of the messages were pilot-tested.

Results

A total of 48 women participated in the FGs. Participants rejected receiving both negative and positive HPV results by SMS because, for them, the delivery of results should be done in a face-to-face interaction with health professionals. They stressed the importance of the SMS content informing them that results were available for pick up and reflecting the kind of relationship that they have with the community health workers and the nearest health center. Women considered that a personalized SMS was important, as was the use of a formal yet warm tone. Owing to confidentiality issues, not using the word “HPV” was also a key component of the desired SMS content; therefore, the final message included the term “self-collection” without the mention of HPV infection. Results from the validation stage and pilot test showed high acceptability of the final version of the message.

Conclusions

The results suggest that SMS is accepted when notifying women about the availability of the HPV test result, but it should not replace the delivery of results in face-to-face, doctor-patient encounters. In addition, messages must be tailored and must have a persuasive tone to motivate women to adhere to the triage.

Programmatic human papillomavirus testing in cervical cancer prevention in the Jujuy Demonstration Project in Argentina: a population-based, before-and-after retrospective cohort study

BACKGROUND

Human papillomavirus (HPV) testing for cervical cancer prevention was introduced in Argentina through the Jujuy Demonstration Project (2011-14). The programme tested women aged 30 years and older attending the public health system with clinician-collected HPV tests. HPV self-collection was introduced as a programmatic strategy in 2014. We aimed to evaluate the effectiveness of programmatic HPV testing to detect cervical intraepithelial neoplasia (CIN) of grade 2 or worse (CIN2+) in comparison with cytology-based screening.

METHODS

We did a population-based, before-and-after retrospective cohort study using data from the National Cervical Cancer Prevention Program for the Jujuy province in northwest Argentina. We obtained data for the cytology-based screening period from Jan 1, 2010, until Dec 31, 2011, and for the HPV-based screening period from Jan 1, 2012, until Dec 31, 2014. The primary outcome was detection of histologically diagnosed CIN2+ among women aged 30 years and older. To assess the outcomes in all individuals included in the study, we used multivariable logistic regression and propensity score matching. The reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework was used for the before-and-after analysis of programmatic dimensions.

FINDINGS

Of the 29 631 women who underwent cytology-based screening in 2010-11, CIN2+ was detected in 236 (0·8%) individuals. Of the 49 565 women HPV tested in 2012-14 (clinician-collected tests, n=44 700; self-collection tests, n=4865), 693 (1·4%; 658 clinician-collected tests; 35 self-collection tests) were found to have CIN2+ after the first round of screening. Compared with cytology-based screening, the odds ratio of being diagnosed with a CIN2+ lesion was 2·34 (95% CI 2·01-2·73; p<0·0010) with clinician-collected tests, and 1·08 (0·74-1·52; p=0·68) when screened with self-collection tests, after controlling for age and health insurance status. Screening coverage was similar in both periods (52·7% vs 53·2%); improvements of programmatic indicators were observed in the HPV testing period in relation to laboratory centralisation, lower overscreening (6·6% vs 0·0%), higher adherance to age recommendations (79·3% vs 98·8%), and a decrease of inadequate samples (3·6% vs 0·2%).

INTERPRETATION

HPV testing in middle-income settings increases detection of CIN2+ lesions and allows for improvement of programmatic indicators. Evidence suggests that the introduction of HPV testing will accelerate the reduction of cervical cancer burden.

Factors associated with low adherence to cervical cancer follow-up retest among HPV+/ cytology negative women: a study in programmatic context in a low-income population in Argentina

BACKGROUND

Cervical Cancer is still a major public health challenge in low and middle-income countries. HPV testing has been an innovative approach, which was introduced in Argentina for women aged 30+ through the Jujuy Demonstration Project (JDP) carried out between 2012 and 2014. After a positive HPV-test, cytology is used as triage method. Under this protocol, the group of women with HPV+ and normal cytology are recommended to repeat the test within 12-18 months. Studies have shown that this group has increased risk of CIN2+, however, assuring high levels of repeating test among these women is difficult to achieve. We analyze those factors associated with lower re-test attendance among HPV+/ cytology negative women at a programmatic level in low-middle income settings.

METHODS

We used data of women aged 30+ HPV-tested in the JDP and followed until 2018 (n = 49,565). We performed a set of different adjusted logistic regression models. Primary outcomes were re-test attendance and re-test attendance within recommended timeframe. We assessed as covariates age, health insurance status, year of HPV-testing, Pap testing in the past 3 years, HPV-testing modality (clinician-collected (CC) tests/self-collected (SC) tests), and span between HPV-test collection and report of results.

RESULTS

Forty nine thousand five hundred sixty five women were HPV-tested and 6742 had a positive HPV-test. Among HPV+ women, a total of 4522 were HPV+/Cytology negative (67.1%). In total, 3172 HPV+/Cytology negative women (70.1%) had a record of a second HPV test as of March 2018. Only 1196 women (26%) completed the second test within the timeframe. Women with no record of a previous Pap (OR: 0.46, 95% CI: 0.4-0.53, p < 0.001), aged 64+ (OR: 0.46, 95% CI: 0.31-0.68, p < 0.001) were less likely to be retested; while women with clinician-collected samples had higher odds of being re-tested (OR: 1.42, 95% CI: 1.06-1.91, p < 0.001).

CONCLUSIONS

Low re-test rates were found in HPV +/ normal cytology women. Tailored interventions are needed to increase the effectiveness of the screening in this group, especially for those women with characteristics associated to lower attendance.

Mixed-methods approach to evaluate an mHealth intervention to increase adherence to triage of human papillomavirus-positive women who have performed self-collection (the ATICA study): study protocol for a hybrid type I cluster randomized effectiveness-implementation trial

BACKGROUND

Cervical cancer is one of the leading causes of cancer death among women worldwide, with more than 85% of cases occurring in low- and middle-income countries. Human papillomavirus (HPV) screening allows for self-collection with the potential to increase coverage, but still requires triage to identify which HPV+ women need diagnostic and treatment procedures. However, achieving high levels of triage adherence can be challenging, especially among socially vulnerable women. This paper describes the ATICA protocol (Application of Communication and Information Technologies to Self-Collection, for its initials in Spanish), aimed at evaluating the implementation strategy and the effectiveness of a multi-component mobile health (mHealth) intervention to increase adherence to triage among women with HPV+ self-collected tests.

METHODS

We will use an effectiveness-implementation hybrid type I trial with a mixed-methods evaluation approach. A cluster randomized trial design including 200 community health workers (CHWs) will evaluate whether the mHealth intervention increases adherence to triage among HPV+ women who self-collected at home during a CHW visit within 120 days after a positive result. The intervention includes an initial mobile phone text message (SMS) alert and subsequent reminders sent to HPV+ women. For those who do not adhere to triage within 60 days of a positive HPV test, an email and SMS will be sent to the CHWs to promote contact with these women during home visits. We will use the Consolidated Framework for Implementation Research (CFIR) as an organizing and analytic framework to evaluate the implementation of the intervention while also drawing on Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM). We will conduct a self-administered, semi-structured survey of CHWs, semi-structured interviews with local health authorities, and a survey of HPV+ women. Combining both qualitative and quantitative data will provide rich insights into local implementation challenges and successes.

DISCUSSION

Findings from the implementation evaluation will be applicable to programs that use or are planning to incorporate HPV self-collection and/or mHealth interventions in different settings and countries. This innovative study will also serve as a model for using implementation science in the region.

[Adoption and implementation of HPV self-collection sampling by CHWs in Jujuy, Argentina]

OBJECTIVE

To evaluate adoption and implementation of scaling up of HPV self-collection (SC) strategy offered doorto-door by Community Health Workers CHWs) in Jujuy, Argentina.

MATERIALS AND METHODS

A self-administered questionnaire was applied to 478 CHWs.RE-AIM model was used to evaluate adoption and implementation dimensions.

RESULTS

Adoption:81.8% offered SC and 86.4% were satis- fied with the strategy. Implementation: main problems were delays in the delivery of tubes (61.3%) and results (70.0%), lack of human resources (28.3%) and difficulties in obtaining an appointment for triage (26.1%). The main obstacle was the excessive workload of CHWs (50.2%).Training (38.0%) and the list of women to be offered the test (28.7%) were identified as facilitators.

CONCLUSIONS

The adoption of SC strategy was high among CHWs.Program strategiesshould be strengthened to motivate and reduce the excessive workload of CHWs when implementing SC strategy.

[Health agents' perspective on the incorporation of self-collected samples in HPV screening programs]

The objective of this study was to analyze health agents' perception of self-collecting of samples for HPV testing among women and the degree of agreement by the agents to incorporate this approach into their daily tasks. A self-administered questionnaire was applied to 127/191 health agents that participated in the EMA Project (Proyecto Evaluación Modalidad Autotoma) in the province of Jujuy, Argentina, in 2012-2013. The health agents with and without the experience of offering self-collected sampling expressed a high degree of agreement towards adoption of the strategy (78.7%), given its potential to prevent cervical cancer and its contribution to health care for the women under their coverage. However, the health agents identified the extra work and problems linking to the formal health system as the main barriers to offering this modality in the future. The study found that self-collecting of samples is a practice that can be adopted by health agents in the province of Jujuy, but that it should be accompanied by support measures from the formal health system.

Evaluation of scaling-up of HPV self-collection offered by community health workers at home visits to increase screening among socially vulnerable under-screened women in Jujuy Province, Argentina

BACKGROUND

Self-collection has been proposed as a strategy to increase cervical screening coverage among hard-to-reach women. However, evaluations of the implementation of this strategy on a large scale are scarce. This paper describes the process and measurement of the scaling-up of self-collection offered by community health workers during home visits as a strategy to reach under-screened women aged 30+ with public health coverage, defined as the target women.

METHODS

We used an adaptation of the Health System Framework to analyze key drivers of scaling-up. A content analysis approach was used to collect and analyze information from different sources. The RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) model was used to evaluate the impact of the strategy.

RESULTS

HPV self-collection was scaled-up in the province of Jujuy in 2014 after a RCT (Self-collection Modality Trial, initials EMA in Spanish) was carried out locally in 2012 and demonstrated effectiveness of the strategy to increase screening uptake. Facilitators of scaling-up were the organizational capacity of the provincial health system, sustainable funding for HPV testing, and local consensus about the value of the technology. Reach: In 2014, 9% (2983/33,245) of target women were screened through self-collection in the Jujuy public health sector. Effectiveness: In 2014, 17% (n = 5657/33,245) of target women were screened with any HPV test (self-collected and clinician-collected tests) vs. 11.7% (4579/38,981) in 2013, the pre-scaling-up period (p < 0.0001).

IMPLEMENTATION

Training about the strategy was provided to 84.2% (n = 609/723) of total community health workers (CHWs). Of 414 HPV+ women, 77.5% (n = 320) had follow-up procedures. Of 113 women with positive triage, 66.4% (n = 75) had colposcopic diagnosis. Treatment was provided to 80.7% of CIN2+ women (n = 21/26). Adoption: Of trained CHWs, 69.3% (n = 422/609) had at least one woman with self-collection; 85.2% (n = 315/368) of CHWs who responded to an evaluation survey were satisfied with self-collection strategy. Maintenance: During 2015, 100.0% (723/723) CHWs were operational and 63.8% (461/723) had at least one woman with self-collection.

CONCLUSIONS

The strategy was successfully scaled-up, with a high level of adoption among CHWs, which resulted in increased screening among socially vulnerable under-screened women.

Implementation of HPV-testing for cervical cancer screening in programmatic contexts: The Jujuy demonstration project in Argentina

The aim of this article is to present results of programmatic introduction of HPV testing with cytologic triage among women 30 years and older in the province of Jujuy, Argentina, including description of the planning phase and results of program performance during the first year. We describe the project implementation process, and calculate key performance indicators using SITAM, the national screening information system. We also compare disease detection rates of HPV testing in 2012 with cytology as performed during the previous year. HPV testing with cytology triage was introduced through a consensus-building process. Key activities included establishment of algorithms and guidelines, creating the HPV laboratory, training of health professionals, information campaigns for women and designing the referral network. By the end of 2012, 100% (n = 270) of public health care centers were offering HPV testing and 22,834 women had been HPV tested, 98.5% (n = 22,515) were 30+. HPV positivity among women over 30 was 12.7%, 807 women were HPV+ and had abnormal cytology, and 281 CIN2+ were identified. CIN2+ detection rates was 1.25 in 2012 and 0.62 in 2011 when the program was cytology based (p = 0.0002). This project showed that effective introduction of HPV testing in programmatic contexts of low-middle income settings is feasible and detects more disease than cytology.

Motion sickness susceptibility in healthy subjects and vestibular patients: effects of gender, age and trait-anxiety

Several studies have suggested that anxiety may play a role in motion sickness susceptibility (MSS) variability. This study aimed to assess motion sickness susceptibility in healthy subjects and chronic vestibular patients and to investigate its relationship to gender, age and trait-anxiety. Healthy subjects (n=167) and chronic dizzy patients with various vestibulopathies (n=94), aged from 20 to 92 years old, were asked to complete Motion Sickness Susceptibility questionnaire (MSSQ) and trait-anxiety questionnaire (STAI-B). When patients were divided into those who had vestibular loss (n=51) vs. patients without vestibular loss (n=43), the MSSQ scores (mean ± SD) for patients with vestibular loss (18.8 ± 30.9) were lower than healthy subjects (36.4 ± 34.8), who were lower than vestibular patients without vestibular loss (59.0 ± 39.7). These significant differences could not be explained by gender, age, trait-anxiety, or interaction. Women had higher MSS than men, and MSS declined with age for healthy subjects and vestibular patients. The overall relationship between anxiety and MSS scores was weak and only reached significance in healthy subjects. These results support the conclusion that the vestibular system is heavily involved in MSS and that trait-anxiety may play a role in MSS but only in healthy subjects.

Hyaluronan derivatives bearing variable densities of ferulic acid residues

A synthetic procedure has been developed to conjugate ferulic acid (FA) to an important natural polysaccharide derivative such as hyaluronic acid (HA). The activation of FA with 1,1'-carbonyldiimidazole (CDI) has been investigated. Two reactive intermediates, namely monoimidazolide 2 [i.e. (E)-3-(4-hydroxy-3-methoxyphenyl)-1-(1H-imidazol-1-yl)prop-2-en-1-one] and bisimidazolide 3 [i.e. (E)-4-(3-(1H-imidazol-1-yl)-3-oxoprop-1-enyl)-2-methoxyphenyl 1H-imidazole-1-carboxylate] were characterized from the point of view of their structure and reactivity. The ready isolation of bisimidazolide 3 and its reactivity support its potential usefulness in the feruloylation of molecular or macromolecular materials bearing hydroxyl moieties. Bisimidazolide derivative 3 has been found to be an effective reagent in the feruloylation of HA to give HAFA graft copolymers showing different grafting degrees (GD), which could be modulated by varying the reaction conditions. A series of HAFA derivatives showing different GD values has been prepared and submitted to an extensive macromolecular and rheological characterization in order to ascertain that the grafting of HA with FA does not degrade the polysaccharide backbone and to evaluate the role of GD in affecting solubility and rheological properties. The results suggested that relatively low GD values were sufficient to confer physical cross-linking capabilities resulting in the features of a strong gel of HAFA dispersions.

[Social determinants of dropout from diagnosis and treatment by women with abnormal Pap smears in Buenos Aires, Argentina]

OBJECTIVE

Determine the extent and reasons why women with abnormal Pap smears drop out from diagnosis and treatment, and the relationship between women's socioeconomic characteristics and dropping out.

METHODS

Cross-sectional retrospective study. Analysis of secondary sources and household interviews with women with abnormal Pap smears seen in the public municipal system from 2009 to 2011.

RESULTS

Confirmed dropout in the study population was 18.3%. Women with the greatest probability of dropping out lived in homes where there were children under five (probability ratio [PR]: 2.4; 95% confidence interval [95%CI]: 1.2-4.8) and where there was overcrowding (PR: 2.9; 95%CI: 1.2-7.3). Women whose initial Pap smear was done in a primary care center had a 4.6 times greater probability of dropping out than those seen in a hospital (95%CI: 1.7-12.3). The main reasons reported for dropping out were problems with health services organization and domestic workload.

CONCLUSIONS

Women's living conditions and the organization and quality of health services affect dropout from diagnosis and treatment of precancerous lesions. Strategies need to be developed that address social determinants of dropping out as a way to ensure effectiveness of cervical cancer screening programs.

[HPV vaccine acceptability and knowledge among gynecologists in Argentina]

OBJECTIVE

To evaluate HPV vaccine acceptability and prescription; knowledge about HPV vaccine; and knowledge about HPV infection and cervical cancer among Argentinean gynecologists.

MATERIALS AND METHODS

Between November 2009 and March 2010 we carried out an internet survey of 686 gynecologists.

RESULTS

More than 80% of gynecologists prescribed HPV vaccine, knew characteristics of HPV vaccines, and knew that women will still need regular cervical cancer screening after HPV vaccination; 37% had global knowledge about relationship between vaccine, detection and treatment of cervical cancer; 25% underestimated the epidemiological extent of HPV infections, ≈30% was not aware of the causative relationship between HPV infection and cervical cancer and ≈40% had global knowledge about management of HPV infection.

CONCLUSIONS

HPV vaccine acceptability is high. Physicians need to be fully informed on HPV vaccination and cervical cancer as well as HPV infection management.

SATB1 collaborates with loss of p16 in cellular transformation

Tumor progression is associated with invasiveness and metastatic potential. The special AT-rich binding protein 1 (SATB1) has been identified as a key factor in the progression of breast cancer cells to a malignant phenotype and is associated with progression of human tumors. In normal development, SATB1 coordinates gene expression of progenitor cells by functioning as a genome organizer. In contrast to progenitor and tumor cells, SATB1 expression in nontransformed cells is not compatible with proliferation. Here we show that SATB1 expression in mouse embryonic fibroblasts induces cell cycle arrest and senescence that is associated with elevated p16 protein levels. Deletion of p16 overcomes the SATB1-induced senescence. We further provide evidence for an interaction of SATB1 with the retinoblastoma (RB)/E2F pathway downstream of p16. A combined deletion of the RB proteins, RB, p107 and p130 (triple-mutant; TM), prevents SATB1-induced G1 arrest, which is restored upon the reintroduction of RB into SATB1-expressing TM fibroblasts. SATB1 interacts with the E2F/RB complex and regulates the cyclin E promoter in an E2F-dependent manner. These findings demonstrate that p16 and the RB/E2F pathway are critical for SATB1-induced cell cycle arrest. In the absence of p16, SATB1 causes anchorage-independent growth and invasive phenotype in fibroblasts. Our data illustrate that p16 mutations collaborate with the oncogenic activity of SATB1. Consistent with our finding, a literature survey shows that deletion of p16 is generally associated with SATB1 expressing human cell lines and tumors.

Analysis of the reasons for abandoning the follow-up and treatment process in women with pre-cancerous cervical lesions in the province of Jujuy: implications for health management

Adequate follow-up and treatment of women with high-grade squamous intraepithelial lesion (HSIL) and cancer is key in reducing cervical cancer mortality. This research study aims to analyze the magnitude of abandonment in the follow-up and treatment process, as well as the reasons for this abandonment, in women with HSIL who received care in public health services in the province of Jujuy in 2010. Secondary sources were analyzed and women were interviewed in their homes. The abandonment rate within the study population was 23.5%. Among these women, 40.5% mentioned organizational problems in the health care system as a reason for abandoning and 30.9% mentioned subjective reasons. Our results have been used in the reorganization of the follow-up and treatment process being carried out in the province.

Intraoperative imprint cytology: its significance as a diagnostic adjunct

We retrospectively evaluated 664 specimens submitted for intraoperative frozen-section analysis for which cytologic imprints or smears were also prepared; 238 (36%) were malignant neoplasms. These preparations were retrospectively evaluated independently by three reviewers of varied experience in the detection of malignancy. The number of false-positive and false-negative results were recorded, and various assessment parameters (sensitivity, specificity, efficiency, and predictive value) were calculated. The imprint was of chief value as an adjunct to the frozen section, particularly in avoiding false-positive and, to a lesser extent, false-negative interpretations. Experience with the use of intraoperative cytology demonstrated the technique to be of value in providing abbreviated preparation time (3-5 min); supportive diagnostic information when frozen section was equivocal; diagnostic information when frozen-section evaluation could not be done (e.g., excessively small sample); contributory information for final diagnosis on difficult cases; and excellent teaching material for cytopathology.
