Evidence-Based Checklist to Delay Cardiac Arrest in Brain-Dead Potential Organ Donors: The DONORS Cluster Randomized Clinical Trial.

Importance: The effectiveness of goal-directed care to reduce loss of brain-dead potential donors to cardiac arrest is unclear. Objective: To evaluate the effectiveness of an evidence-based, goal-directed checklist in the clinical management of brain-dead potential donors in the intensive care unit (ICU). Design, Setting, and Participants: The Donation Network to Optimize Organ Recovery Study (DONORS) was an open-label, parallel-group cluster randomized clinical trial in Brazil. Enrollment and follow-up were conducted from June 20, 2017, to November 30, 2019. Hospital ICUs that reported 10 or more brain deaths in the previous 2 years were included. Consecutive brain-dead potential donors in the ICU aged 14 to 90 years with a condition consistent with brain death after the first clinical examination were enrolled. Participants were randomized to either the intervention group or the control group. The intention-to-treat data analysis was conducted from June 15 to August 30, 2020. Interventions: Hospital staff in the intervention group were instructed to administer to brain-dead potential donors in the intervention group an evidence-based checklist with 13 clinical goals and 14 corresponding actions to guide care, every 6 hours, from study enrollment to organ retrieval. The control group provided or received usual care. Main Outcomes and Measures: The primary outcome was loss of brain-dead potential donors to cardiac arrest at the individual level. A prespecified sensitivity analysis assessed the effect of adherence to the checklist in the intervention group. Results: Among the 1771 brain-dead potential donors screened in 63 hospitals, 1535 were included. These patients included 673 males (59.2%) and had a median (IQR) age of 51 (36.3-62.0) years. The main cause of brain injury was stroke (877 [57.1%]), followed by trauma (485 [31.6%]). Of the 63 hospitals, 31 (49.2%) were assigned to the intervention group (743 [48.4%] brain-dead potential donors) and 32 (50.8%) to the control group (792 [51.6%] brain-dead potential donors). Seventy potential donors (9.4%) at intervention hospitals and 117 (14.8%) at control hospitals met the primary outcome (risk ratio [RR], 0.70; 95% CI, 0.46-1.08; P = .11). The primary outcome rate was lower in those with adherence higher than 79.0% than in the control group (5.3% vs 14.8%; RR, 0.41; 95% CI, 0.22-0.78; P = .006). Conclusions and Relevance: This cluster randomized clinical trial was inconclusive in determining whether the overall use of an evidence-based, goal-directed checklist reduced brain-dead potential donor loss to cardiac arrest. The findings suggest that use of such a checklist has limited effectiveness without adherence to the actions recommended in this checklist.

Is the press properly presenting the epidemiological data on COVID-19? An analysis of newspapers from 25 countries.

We conducted a cross-sectional study to assess how the top 3 highest circulation newspapers from 25 countries are comparing and presenting COVID-19 epidemiological data to their readers. Of 75 newspapers evaluated, 51(68%) presented at their websites at least one comparison of cases and/or deaths between regions of their country and/or between countries. Quality assessment of the comparisons showed that only a minority of newspapers adjusted the data for population size in case comparisons between regions (37.2%) and between countries (25.6%), and the same was true for death comparisons between regions (27.3%) and between countries (27%). Of those making comparisons, only 13.7% explained the difference in the interpretation of cases and deaths. Of 17 that presented a logarithmic curve, only 29.4% explained its meaning. Although the press plays a key role in conveying correct medical information to the general public, we identified inconsistencies in the reporting of COVID-19 epidemiological data.

INTRODUCTION: The long-term effects caused by COVID-19 are unknown. The present study aims to assess factors associated with health-related quality of life and long-term outcomes among survivors of hospitalization for COVID-19 in Brazil. METHODS: This is a multicenter prospective cohort study nested in five randomized clinical trials designed to assess the effects of specific COVID-19 treatments in over 50 centers in Brazil. Adult survivors of hospitalization due to proven or suspected SARS-CoV-2 infection will be followed-up for a period of 1 year by means of structured telephone interviews. The primary outcome is the 1-year utility score of health-related quality of life assessed by the EuroQol-5D3L. Secondary outcomes include all-cause mortality, major cardiovascular events, rehospitalizations, return to work or study, physical functional status assessed by the Lawton-Brody Instrumental Activities of Daily Living, dyspnea assessed by the modified Medical Research Council dyspnea scale, need for long-term ventilatory support, symptoms of anxiety and depression assessed by the Hospital Anxiety and Depression Scale, symptoms of posttraumatic stress disorder assessed by the Impact of Event Scale-Revised, and self-rated health assessed by the EuroQol-5D3L Visual Analog Scale. Generalized estimated equations will be performed to test the association between five sets of variables (1- demographic characteristics, 2- premorbid state of health, 3- characteristics of acute illness, 4- specific COVID-19 treatments received, and 5- time-updated postdischarge variables) and outcomes. ETHICS AND DISSEMINATION: The study protocol was approved by the Research Ethics Committee of all participant institutions.

Statistical analysis plan for a cluster-randomised trial assessing the effectiveness of implementation of a bedside evidence-based checklist for clinical management of brain-dead potential organ donors in intensive care units: DONORS (Donation Network to Optimise Organ Recovery Study).

BACKGROUND: The quality of clinical care of brain-dead potential organ donors may help reduce donor losses caused by irreversible or unreversed cardiac arrest and increase the number of organs donated. We sought to determine whether an evidence-based, goal-directed checklist for donor management in intensive care units (ICUs) can reduce donor losses to cardiac arrest. METHODS/DESIGN: The DONORS study is a multicentre, cluster-randomised controlled trial with a 1:1 allocation ratio designed to compare an intervention group (goal-directed checklist for brain-dead potential organ donor management) with a control group (standard ICU care). The primary outcome is loss of potential donors due to cardiac arrest. Secondary outcomes are the number of actual organ donors and the number of solid organs recovered per actual donor. Exploratory outcomes include the achievement of relevant clinical goals during the management of brain-dead potential organ donors. The present statistical analysis plan (SAP) describes all primary statistical procedures that will be used to evaluate the results and perform exploratory and sensitivity analyses of the trial. DISCUSSION: The SAP of the DONORS study aims to describe its analytic procedures, enhancing the transparency of the study. At the moment of SAP subsmission, 63 institutions have been randomised and were enrolling study participants. Thus, the analyses reported herein have been defined before the end of the study recruitment and database locking. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03179020. Registered on 7 June 2017.

Effect of Flexible Family Visitation on Delirium Among Patients in the Intensive Care Unit: The ICU Visits Randomized Clinical Trial.

Importance: The effects of intensive care unit (ICU) visiting hours remain uncertain. Objective: To determine whether a flexible family visitation policy in the ICU reduces the incidence of delirium. Design, Setting and Participants: Cluster-crossover randomized clinical trial involving patients, family members, and clinicians from 36 adult ICUs with restricted visiting hours (<4.5 hours per day) in Brazil. Participants were recruited from April 2017 to June 2018, with follow-up until July 2018. Interventions: Flexible visitation (up to 12 hours per day) supported by family education (n = 837 patients, 652 family members, and 435 clinicians) or usual restricted visitation (median, 1.5 hours per day; n = 848 patients, 643 family members, and 391 clinicians). Nineteen ICUs started with flexible visitation, and 17 started with restricted visitation. Main Outcomes and Measures: Primary outcome was incidence of delirium during ICU stay, assessed using the CAM-ICU. Secondary outcomes included ICU-acquired infections for patients; symptoms of anxiety and depression assessed using the HADS (range, 0 [best] to 21 [worst]) for family members; and burnout for ICU staff (Maslach Burnout Inventory). Results: Among 1685 patients, 1295 family members, and 826 clinicians enrolled, 1685 patients (100%) (mean age, 58.5 years; 47.2% women), 1060 family members (81.8%) (mean age, 45.2 years; 70.3% women), and 737 clinicians (89.2%) (mean age, 35.5 years; 72.9% women) completed the trial. The mean daily duration of visits was significantly higher with flexible visitation (4.8 vs 1.4 hours; adjusted difference, 3.4 hours [95% CI, 2.8 to 3.9]; P < .001). The incidence of delirium during ICU stay was not significantly different between flexible and restricted visitation (18.9% vs 20.1%; adjusted difference, -1.7% [95% CI, -6.1% to 2.7%]; P = .44). Among 9 prespecified secondary outcomes, 6 did not differ significantly between flexible and restricted visitation, including ICU-acquired infections (3.7% vs 4.5%; adjusted difference, -0.8% [95% CI, -2.1% to 1.0%]; P = .38) and staff burnout (22.0% vs 24.8%; adjusted difference, -3.8% [95% CI, -4.8% to 12.5%]; P = .36). For family members, median anxiety (6.0 vs 7.0; adjusted difference, -1.6 [95% CI, -2.3 to -0.9]; P < .001) and depression scores (4.0 vs 5.0; adjusted difference, -1.2 [95% CI, -2.0 to -0.4]; P = .003) were significantly better with flexible visitation. Conclusions and Relevance: Among patients in the ICU, a flexible family visitation policy, vs standard restricted visiting hours, did not significantly reduce the incidence of delirium.

DONORS (Donation Network to Optimise Organ Recovery Study): Study protocol to evaluate the implementation of an evidence-based checklist for brain-dead potential organ donor management in intensive care units, a cluster randomised trial.

INTRODUCTION: There is an increasing demand for multi-organ donors for organ transplantation programmes. This study protocol describes the Donation Network to Optimise Organ Recovery Study, a planned cluster randomised controlled trial that aims to evaluate the effectiveness of the implementation of an evidence-based, goal-directed checklist for brain-dead potential organ donor management in intensive care units (ICUs) in reducing the loss of potential donors due to cardiac arrest. METHODS AND ANALYSIS: The study will include ICUs of at least 60 Brazilian sites with an average of ≥10 annual notifications of valid potential organ donors. Hospitals will be randomly assigned (with a 1:1 allocation ratio) to the intervention group, which will involve the implementation of an evidence-based, goal-directed checklist for potential organ donor maintenance, or the control group, which will maintain the usual care practices of the ICU. Team members from all participating ICUs will receive training on how to conduct family interviews for organ donation. The primary outcome will be loss of potential donors due to cardiac arrest. Secondary outcomes will include the number of actual organ donors and the number of organs recovered per actual donor. ETHICS AND DISSEMINATION: The institutional review board (IRB) of the coordinating centre and of each participating site individually approved the study. We requested a waiver of informed consent for the IRB of each site. Study results will be disseminated to the general medical community through publications in peer-reviewed medical journals. TRIAL REGISTRATION NUMBER: NCT03179020; Pre-results.

Hospital quality indicators: a systematic review.

PURPOSE: The purpose of this paper is to identify and describe hospital quality indicators, classifying them according to Donabedian's structure, process and outcome model and in specific domains (quality, safety, infection and mortality) in two care divisions: inpatient and emergency services. DESIGN/METHODOLOGY/APPROACH: A systematic review identified hospital clinical indicators. Two independent investigators evaluated 70 articles/documents located in electronic databases and nine documents from the grey literature, 35 were included in the systematic review. FINDINGS: In total, 248 hospital-based indicators were classified as infection, safety, quality and mortality domains. Only 10.2 percent were identified in more than one article/document and 47 percent showed how they were calculated/obtained. Although there are scientific papers on developing, validating and hospital indicator assessment, most indicators were obtained from technical reports, government publications or health professional associations. RESEARCH LIMITATIONS/IMPLICATIONS: This review identified several hospital structure, process and outcome quality indicators, which are used by different national and international groups in both research and clinical practice. Comparing performance between healthcare organizations was difficult. Common clinical care standard indicators used by different networks, programs and institutions are essential to hospital quality benchmarking. ORIGINALITY/VALUE: To the authors' knowledge, this is the first systematic review to identify and describe hospital quality indicators after a comprehensive search in MEDLINE/PubMed, etc., and the grey literature, aiming to identify as many indicators as possible. Few studies evaluate the indicators, and most are found only in the grey literature, and have been published mostly by government agencies. Documents published in scientific journals usually refer to a specific indicator or to constructing an indicator. However, indicators most commonly found are not supported by reliability or validity studies.

RESUMO Objetivo: Avaliar a prevalência de incapacidades físicas, cognitivas e psiquiátricas, fatores associados e sua relação com qualidade de vida em pacientes sobreviventes de internação em unidades de terapia intensiva brasileiras. Métodos: Um estudo de coorte prospectivo multicêntrico está sendo conduzido em dez unidades de terapia intensiva adulto clínico-cirúrgicas representativas das cinco regiões geopolíticas do Brasil. Pacientes com idade ≥ 18 anos que receberam alta das unidades de terapia intensiva participantes e permaneceram internados na unidade de terapia intensiva por 72 horas ou mais, nos casos de internação clínica ou cirúrgica de urgência, e por 120 horas ou mais, nos casos de internação cirúrgica eletiva, serão incluídos de forma consecutiva. Estes pacientes serão seguidos por 1 ano, por meio de entrevistas telefônicas estruturadas 3, 6 e 12 meses pós-alta da unidade de terapia intensiva. Dependência funcional, disfunção cognitiva, sintomas de ansiedade e depressão, sintomas de estresse pós-traumático, qualidade de vida relacionada à saúde, re-hospitalizações e mortalidade em longo prazo serão avaliados como desfechos. Discussão: O presente estudo tem o potencial de contribuir para o conhecimento a respeito da prevalência e dos fatores associados à síndrome pós-cuidados intensivos na população de pacientes adultos sobreviventes de internação em unidades de terapia intensiva brasileiras. Ademais, a associação entre síndrome pós-cuidados intensivos e qualidade de vida relacionada à saúde poderá ser estabelecida.

ABSTRACT Objective: To establish the prevalence of physical, cognitive and psychiatric disabilities, associated factors and their relationship with the qualities of life of intensive care survivors in Brazil. Methods: A prospective multicenter cohort study is currently being conducted at 10 adult medical-surgical intensive care units representative of the 5 Brazilian geopolitical regions. Patients aged ≥ 18 years who are discharged from the participating intensive care units and stay 72 hours or more in the intensive care unit for medical or emergency surgery admissions or 120 hours or more for elective surgery admissions are consecutively included. Patients are followed up for a period of one year by means of structured telephone interviews conducted at 3, 6 and 12 months after discharge from the intensive care unit. The outcomes are functional dependence, cognitive dysfunction, anxiety and depression symptoms, posttraumatic stress symptoms, health-related quality of life, rehospitalization and long-term mortality. Discussion: The present study has the potential to contribute to current knowledge of the prevalence and factors associated with postintensive care syndrome among adult intensive care survivors in Brazil. In addition, an association might be established between postintensive care syndrome and health-related quality of life.

POP-Brazil study protocol: a nationwide cross-sectional evaluation of the prevalence and genotype distribution of human papillomavirus (HPV) in Brazil.

INTRODUCTION: Human papillomavirus (HPV) is associated with the development of genital warts and different types of cancer, including virtually all cervical cancers and a considerable number of penile, anal and oropharyngeal cancers. Data regarding the prevalence of HPV infection in Brazil are limited and fragmented. We aim to determine HPV prevalence in sexually active women and men aged 16-25 years and to investigate regional differences in virus prevalence and types. METHODS AND ANALYSIS: This is a nationwide, multicentric, cross-sectional, prospective study that will include participants aged 16-25 years from all Brazilian capital cities. Recruitment will occur in primary health units by trained health professionals who will be responsible for collecting biological samples and interviewing the volunteers. After signing informed consent, all participants will answer a questionnaire that will collect sociodemographic and behavioural data. All samples will be processed in a certified central laboratory, and strict quality control will be performed by many different procedures, including double data entry, training and certification of primary care health professionals responsible for data collection, simulation of interviews, and auditing and monitoring of visits. The sample size will be standardised based on the population distribution of each capital using SAS and R statistical software. ETHICS AND DISSEMINATION: The project was approved by the research ethics committee of the main institution and the corresponding ethics committees of the recruitment sites. This will be the first Brazilian nationwide study to determine overall HPV prevalence and to examine regional differences and social, demographic and behavioural factors related to HPV infection. Critical analysis of the study results will contribute to epidemiological knowledge and will set a baseline for future evaluation of the impact of the National HPV Vaccination Program.

Assessment of potential risk factors for breast cancer in a population in Southern Brazil.

PURPOSE: The aim of this study is to assess potential risk factors for breast cancer in a population in Southern Brazil and build a multivariate logistic model using these factors for breast cancer risk prediction. METHODS: A total of 4242 women between 40 and 69 years of age without a history of breast cancer were selected at primary healthcare facilities in Porto Alegre and submitted to mammographic screening. They were evaluated for potential risk factors. RESULTS: In all, 73 participants among the 4242 women had a breast cancer diagnosis during the follow-up of the project (10 years). The multivariate analysis considering all the patients aged 40-69 years showed that older age (OR 1.08, 95% CI 1.04-1.12), higher height (OR 1.04, 95% CI 1.01-1.09), and history of previous breast biopsy (OR 2.66, 95% CI 1.38-5.13) were associated with the development of breast cancer. Conversely, the number of pregnancies (OR 0.87, 95% CI 0.78-0.98) and use of hormone replacement therapy (OR 0.39, 95% CI 0.20-0.75) were considered a protective factor. Additionally, we performed an analysis separating the participants into groups of 40-49 and 50-69 years old, since a risk factor could have a specific behavior in these age groups. No additional risk factors were identified within these age brackets, and some factors lost statistical significance. CONCLUSION: The risk prediction model indicates that the following variables should be assessed in this specific population: age, height, having had previous breast biopsies, number of pregnancies, and use of hormone replacement therapy. These findings may help to better understand the causal model of breast cancer in Southern Brazil.

Carcinogenesis of Vulvar Lesions: Morphology and Immunohistochemistry Evaluation.

OBJECTIVES: The aim of the study was to assess the 2 pathways of vulvar carcinogenesis and correlate immunohistochemical expression of p53 with histopathological findings. MATERIALS AND METHODS: This cross-sectional study included 76 cases. Patients were classified according to the 2004 International Society for the Study of Vulvovaginal Disease Terminology, followed by a review of clinical records and immunohistochemical staining for p53. RESULTS: Fifteen cases were in the human papillomavirus (HPV)-associated pathway (12 cases of usual vulvar intraepithelial neoplasia [VIN] and 3 of warty squamous cell carcinoma [SCC]), and 13 cases were in the HPV-independent pathway (5 cases of differentiated VIN and 8 of keratinizing SCC). Significant differences in p53 expression were observed between the 2 pathways of carcinogenesis: in the lesions related to the HPV-independent pathway, the percentage of p53-positive cells was greater (>25%, p < .001), and the staining pattern was basal (extending into the middle layer) in differentiated VIN and diffuse or infiltrative in warty SCC (p < 0.001). In the lesions HPV-associated pathway, p53 staining was less extensive (≤10% of cells, p < 0.001) and followed basal pattern in usual VIN, whereas warty SCCs were negative for p53 (p < 0.001). CONCLUSIONS: Unique patterns of histological appearance and p53 expression can separate vulvar lesions into 2 distinct pathways of carcinogenesis. We propose that p53 immunohistochemistry may be performed simultaneously with histopathological examination in all cases of VIN and vulvar SCC, because it would aid in definition of the pathway of carcinogenesis and thus enable better clinical follow-up of patients with these conditions.

Prevalence of papillomavirus in Brazil: a systematic review protocol.

INTRODUCTION: Human papillomavirus (HPV) infection is a cause of premalignant and malignant cancer in the lower genital and digestive tracts. In Brazil, there have been no prevalence studies that included a nationwide sample, and the prevalence of HPV has not been determined in many regions. METHODS: We will search the EMBASE, LILACS, MEDLINE, Web of Science and SciELO databases and previously published review articles to identify original research articles assessing HPV prevalence of the perineal (cervical, penile and anal) and oral areas. No exclusion criteria related to language or publication date will apply. 2 reviewers will independently screen for eligibility and perform data extraction. Discrepancies will be resolved through consensus; the opinion of a third reviewer will be sought as necessary. Relevant measures and data about study and population characteristics will be extracted from the included studies. Where possible, study prevalence will be pooled using a random-effects meta-analysis. The methodological quality of the studies will be assessed using an adapted version of the NIH 'Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies'. The overall quality of evidence will be assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE). ETHICS AND DISSEMINATION: We expect to estimate the prevalence of perineal and oral HPV infection in the general population as well as the prevalence of HPV infection in individuals with premalignant and malignant lesions in Brazil and its 5 geographic regions. This systematic review does not require ethical approval. TRIAL REGISTRATION NUMBER: CRD42016032751.

Effectiveness of pharmaceutical care at discharge in the emergency department: study protocol of a randomized controlled trial.

BACKGROUND: Patient education on pharmacological therapy may increase medication adherence and decrease hospitalizations. Our aim is to evaluate the effectiveness of pharmaceutical care at emergency department discharge in patients with hypertension and/or diabetes. METHODS/DESIGN: This is a randomized controlled trial. Participants will be recruited from a public emergency department at Restinga district in Porto Alegre, southern Brazil. A total of 380 patients will be randomly assigned into 2 groups at the moment of emergency department discharge after receiving medical orientations: an intervention group, consisting of a structured individual counseling session by a pharmacist in addition to written orientations, or a control group, consisting only of written information about the disease. Outcomes will be assessed in an ambulatory visit 2 months after the randomization. The primary outcome is the proportion of patients with high medication adherence assessed using the Morisky-Green Test and the Brief Medication Questionnaire. The secondary outcomes are reduction of blood pressure, glycated hemoglobin, fasting plasma glucose, quality of life and number of visits to the emergency department. DISCUSSION: Pharmaceutical care interventions have shown to be feasible and effective in increasing medication adherence in both hospital outpatient and community pharmacy settings. However, there have been no previous assessments of the effectiveness of pharmacy care interventions initiated in patients discharged from emergency departments. Our hypothesis is that pharmaceutical counseling is also effective in this population.

Effects of lifestyle modification after breast cancer treatment: a systematic review protocol.

BACKGROUND: There is no consensus in the literature regarding the effectiveness of lifestyle modification interventions, including recommendations about specific diet or exercise program for patients with breast cancer. Diet interventions and regular physical activity may reduce the risk of breast cancer and its recurrence. The primary aim of our study is to evaluate the effects of different lifestyle modification interventions (diet and physical activity) in the survival of patients with stages I to III breast cancer after treatment. METHODS/DESIGN: This review will be conducted according to the Cochrane Handbook for Systematic Reviews of Intervention and will be reported following the PRISMA statement recommendations. CENTRAL, MEDLINE and EMBASE databases will be searched for peer-reviewed literature. Randomized controlled trials of diet, exercise, or both, compared with usual care, after treatment of breast cancer stage I to III will be included in the systematic review. Two authors will independently screen titles and abstracts of studies for potential eligibility. Data will be combined using random-effect meta-analysis models with restricted maximum-likelihood as variance estimator, and will be presented as relative risk or standardized mean difference with 95% CI. The quality of evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework and summary of findings tables will be presented for patient important outcomes. DISCUSSION: Our study may improve the current understanding of the role that lifestyle-modifiable factors can play in saving or prolonging the lives of women who have been treated for breast cancer, and also on modifying their quality of life. SYSTEMATIC REVIEW REGISTRATION: The review has been registered with PROSPERO (registration number CRD42014008743).

Cervical digital photography for screening of uterine cervix cancer and its precursor lesions in developing countries.

PURPOSE: This study aims to evaluate and to compare the performance of cervical digital photography (CDP) to the visual inspection with acetic acid (VIA) and visual inspection with Lugol's iodine (VILI) methods for screening the uterine cervix cancer and its precursor lesions in developing countries. METHODS: A cross-sectional study was performed in Brazil. 176 women were evaluated by VIA, VILI, CDP with acetic acid and CDP with Lugol's iodine. Kappa statistic was used to estimate the interobserver and intermethod agreement. Sensitivity, specificity and diagnostic accuracy of the four methods (VIA, VILI, CDP with acetic acid, CDP with Lugol's iodine) was calculated. RESULTS: Interobserver agreement for CDP with acetic acid was K = 0.441 and for CDP with Lugol's iodine was K = 0.533; intermethod agreement of VIA and CDP with acetic acid, K = 0.559; and of VILI and CDP with Lugol's iodine, K = 0.507. Sensitivity and specificity of CDP with acetic acid were 84.00 and 95.83 %, and of CDP with Lugol's iodine were 88.00 and 97.26 %, respectively. The diagnostic accuracy of CDP with acetic acid and CDP with Lugol's iodine was 92.78 and 94.90 %, respectively. CONCLUSION: This was the first study to assess the CDP with Lugol's iodine performance, which had similar performance to the CDP with acetic acid. CDP is considered a promising method for screening the uterine cervix cancer and its precursor lesions in developing countries.

Performance characteristics of Pap test, VIA, VILI, HR-HPV testing, cervicography, and colposcopy in diagnosis of significant cervical pathology.

We sought to evaluate the performance of diagnostic tools to establish an affordable setting for early detection of cervical cancer in developing countries. We compared the performance of different screening tests and their feasibility in a cohort of over 12,000 women: conventional Pap smear, liquid-based cytology, visual inspection with acetic acid (VIA), visual inspection with Iodine solution (VILI), cervicography, screening colposcopy, and high-risk human papillomavirus (HPV) testing (HR-HPV) collected by physician and by self-sampling. HR-HPV assay collected by the physician has the highest sensitivity (80 %), but high unnecessary referrals to colposcopy (15.1 %). HR-HPV test in self-sampling had a markedly lower (57.1 %) sensitivity. VIA, VILI, and cervicography had a poor sensitivity (47.4, 55, and 28.6 %, respectively). Colposcopy presented with sensitivity of 100 % in detecting CIN2+, but the lowest specificity (66.9 %). Co-testing with VIA and VILI Pap test increased the sensitivity of stand-alone Pap test from 71.6 to 87.1 % and 71.6 to 95 %, respectively, but with high number of unnecessary colposcopies. Co-testing with HR-HPV importantly increased the sensitivity of Pap test (to 86 %), but with high number of unnecessary colposcopies (17.5 %). Molecular tests adjunct to Pap test seems a realistic option to improve the detection of high-grade lesions in population-based screening programs.

Hormonal contraceptives and the length of their use are not independent risk factors for high-risk HPV infections or high-grade CIN.

AIMS: To evaluate the role of hormonal contraceptives as a risk factor of high-risk human papillomavirus (HR-HPV), cervical intraepithelial lesions (CIN) and cervical cancer in our multi-center population-based LAMS (Latin American Screening) study. METHODS: A cohort study with >12,000 women from Brazil and Argentina using logistic regression to analyze the covariates of hormonal contraception (HOC - oral, injections, patches, implants, vaginal ring and progesterone intrauterine system) use followed by multivariate modeling for predictors of HR-HPV and CIN2+. RESULTS: HR-HPV infection was a consistent risk factor of high-grade CIN in all three groups of women. The length of HOC use was not significantly related to high-grade squamous intraepithelial lesions (HSIL)+ Pap (p = 0.069), LSIL+ Pap (p = 0.781) or ASCUS+ (p = 0.231). The same was true with the length of HOC use and histology CIN3+ (p = 0.115) and CIN2+ (p = 0.515). Frequently, HOC users have previously shown more HPV-related lesions, as well as lower HPV prevalence if they were current smokers. But HOC use and time of usage were not independent risk factors of either HR-HPV infection or high-grade CIN using multiple logistic regressions. CONCLUSIONS: No evidence was found for an association between the use of HOC with an increased risk for HR-HPV infection or high-grade CIN in this cohort.

Persistent high-risk human papillomavirus infections and other end-point markers of progressive cervical disease among women prospectively followed up in the New Independent States of the Former Soviet Union and the Latin American Screening study cohorts.

BACKGROUND: New end points are needed in future human papillomavirus (HPV) vaccine efficacy studies that accurately predict disease progression. OBJECTIVES: Potential intermediate end points were analyzed in the combined New Independent States of the Former Soviet Union (NIS) and the Latin American Screening (LAMS) study cohorts. STUDY DESIGN AND METHODS: Data files of 2 international screening trials, the NIS (n = 3187) and the LAMS (n = 12,114) study cohorts, were combined, and a subcohort of 1865 (n = 854 and n = 1011 for the NIS and the LAMS, respectively) women prospectively followed up for 19.7 (median, 22.2) months was analyzed for different intermediate end-point markers of disease progression to squamous intraepithelial lesion (SIL), cervical intraepithelial neoplasia grade 1 and higher (CIN1+), and CIN grade 2 and higher (CIN2+) as terminal events. RESULTS: : Altogether, 131 (7.0%), 90 (4.8%), and 39 (2.1%) cases progressed to SIL, CIN1+, and CIN2+, respectively, progression times being equal in the NIS (11.9, 16.8, and 19.6 months) and LAMS (13.6, 14.1, and 15.4 months) cohorts (P = 0.931, P = 0.335, and P = 0.535). The 2 most powerful end-point markers of disease progression to CIN2+ were high-grade squamous intraepithelial lesions based on Papanicolaou test results at 6-month (odds ratio [OR] = 47.1; 95% confidence interval [CI], 17.3-128.7) and 12-month (OR = 21.5; 95% CI, 5.1-90.8) follow-up visits, with longitudinal positive and negative predictive values of 42.1% and 98.0% (6 months) and 33.3% and 97.7% (12 months). Of the virological end points, more than 6 months of persistent high-risk HPV (HR-HPV) was the most powerful predictor of progression to CIN1+ (OR = 18.6; 95% CI, 2.5-136.5), with longitudinal positive and negative predictive values of 10.3% and 99.4%, respectively. No additional benefit was obtained using more than 12 months of persistent HR-HPV end point. CONCLUSIONS: High-grade squamous intraepithelial lesion based on a Papanicolaou test results at 6- or 12-month follow-up visits was the most powerful end point, either considering cytological end points alone or in comparison to any of the virological end points. Of the virological end points, more than 6-month HR-HPV persistence criteria give the most powerful estimate of a progressive disease.
