Background There is considerable heterogeneity in individuals’ risk of disease and thus the absolute benefits and harms of population-wide screening programmes. Using colorectal cancer (CRC) screening as an exemplar, we explored how people make decisions about screening when presented with information about absolute benefits and harms, and how those preferences vary with baseline risk, between screening tests and between individuals. Method We conducted two linked studies with members of the public: a think-aloud study exploring decision making in-depth and an online randomised experiment quantifying preferences. In both, participants completed a web-based survey including information about three screening tests (colonoscopy, sigmoidoscopy, and faecal immunochemical testing) and then up to nine scenarios comparing screening to no screening for three levels of baseline risk (1%, 3% and 5% over 15 years) and the three screening tests. Participants reported, after each scenario, whether they would opt for screening (yes/no). Results Of the 20 participants in the think-aloud study 13 did not consider absolute benefits or harms when making decisions concerning CRC screening. In the online experiment (n = 978), 60% expressed intention to attend at 1% risk of CRC, 70% at 3% and 77% at 5%, with no differences between screening tests. At an individual level, 535 (54.7%) would attend at all three risk levels and 178 (18.2%) at none. The 27% whose intention varied by baseline risk were more likely to be younger, without a family history of CRC, and without a prior history of screening. Conclusions Most people in our population were not influenced by the range of absolute benefits and harms associated with CRC screening presented. For an appreciable minority, however, magnitude of benefit was important.

This study sought to describe the colorectal cancer (CRC)-screening behavior of a population of two lower income communities near Pittsburgh, Pennsylvania. The transtheoretical model was used to characterize individuals according to their stage of readiness to engage in one of two recommended CRC screening tests—the Fecal Occult Blood Test (FOBT) or Flexible Sigmoidoscopy (FSG) test. A telephone survey was conducted of 50- to 79-year-old men and women in Aliquippa and Clairton in the spring of 1999. Analyses based on 414 survey respondents showed associations between FOBT or FSG behavioral stage and factors including gender, age, recent doctor checkup, chronic need for prescription medications, history of cervical Pap smear testing, history of prostate-specific antigen blood testing, and prior doctor recommendation in favor of FOBT or FSG testing. This study appears to be one of the first applications of this theory to understanding CRC screening behavior in a community intervention.

69 Background: The Healthy People 2020 initiative aims to increase colorectal cancer (CRC) screening. The common CRC screening options are FIT, FOBT, sigmoidoscopy, and colonoscopy. Colonoscopy allows visualization of the entire colon and offers therapeutic benefit whereas stool tests are less invasive, cost-effective and are easily available. Inequities exist in CRC screening among rural residents which may be contributed to a lower level of education, income, health insurance and access to health care. The purpose of the study is to identify the impact of geographic region on the preference of CRC screening modality among Louisiana adults. Methods: We performed a retrospective cohort study among age-eligible Louisiana adults who had CRC screening either with colonoscopy or stool-based tests using the 2016 Behavioral Risk Factor Surveillance System database (n = 1372). We examined demographic characteristics among participants who had CRC screening with colonoscopy versus who had a stool-based test. Multivariable logistic regression analysis evaluated the association of geographic region and the preference of CRC screening. Results: Participants age 65-75 years old were 36% less likely to have a colonoscopy as compared to age 50-64 years (p = 0.0008). African Americans and Hispanic Americans were 34% (p < 0.006) and 55% (p = 0.057) less likely to have a colonoscopy as compared to Caucasian Americans, respectively. Medicaid and Medicare participants were 82% (p < 0.0001) and 52% (p < 0.0001) less likely to have a colonoscopy compared to participants with private insurance, respectively. After adjusting for age, race/ethnicity, education, income, and insurance the odds of screening colonoscopy was 29% lower for rural residents compared to urban residents of Louisiana (OR 0.71 95% CI 0.53 - 0.94). Conclusions: Individuals residing in rural parishes of Louisiana were more likely to have a stool-based test for CRC screening. Health care providers while considering the reliability and feasibility of CRC screening modality should also incorporate patient’s preferences while offering the screening tests to increase the rate of CRC screening.

The epidemiology and the current burden of chronic liver disease are changing globally, with non-alcoholic fatty liver disease (NAFLD) becoming the most frequent cause of liver disease in close relationship with the global epidemics of obesity, type 2 diabetes and metabolic syndrome. The clinical phenotypes of NAFLD are very heterogeneous in relationship with multiple pathways involved in the disease progression. In the absence of a specific treatment for non-alcoholic steatohepatitis (NASH), it is important to understand the natural history of the disease, to identify and to optimize the control of factors that are involved in disease progression. In this paper we propose a critical analysis of factors that are involved in the progression of the liver damage and the occurrence of extra-hepatic complications (cardiovascular diseases, extra hepatic cancer) in patients with NAFLD. We also briefly discuss the impact of the heterogeneity of the clinical phenotype of NAFLD on the clinical practice globally and at the individual level.

We aimed to report the results of the implementation of the National Colorectal Cancer (CRC) Screening Program covering all the country. The National Health Insurance Fund (NHIF) reimburses the institutions for performing each service; each procedure within the program has its own administrative code. Information about services provided within the program was retrieved from the database of NHIF starting from the 1 January 2014 to the 31 December 2018. Exact date and type of all provided services, test results, date and results of biopsy and histopathological examination were extracted together with the vital status at the end of follow-up, date of death and date of emigration when applicable for all men and women born between 1935 and 1968. Results were compared with the guidelines of the European Union for quality assurance in CRC screening and diagnosis. The screening uptake was 49.5% (754,061 patients) during study period. Participation rate varied from 16% to 18.1% per year and was higher among women than among men. Proportion of test-positive and test-negative results was similar during all the study period—8.7% and 91.3% annually. Between 9.2% and 13.5% of test-positive patients received a biopsy of which 52.3–61.8% were positive for colorectal adenoma and 4.6–7.3% for colorectal carcinoma. CRC detection rate among test-positive individuals varied between 0.93% and 1.28%. The colorectal cancer screening program in Lithuania coverage must be improved. A screening database is needed to systematically evaluate the impact and performance of the national CRC screening program and quality assurance within the program.

Despite the effectiveness of screenings in reducing colorectal cancer (CRC) mortality, ~25% of US adults do not adhere to screening guidelines. Prior studies associate socioeconomic status (SES) with low screening adherence and suggest that neighborhood deprivation can influence CRC outcomes. We comprehensively investigated the effect of neighborhood SES circumstances (nSES), individual SES, and race/ethnicity on adherence to CRC screening in a multiethnic cross-sectional study. Participant surveys assessing 32 individual-level socioeconomic and healthcare access measures were administered from 2017 to 2018. Participant data were joined with nine nSES measures from the US Census at the census tract level. Univariate, LASSO, and multivariable mixed-effect logistic regression models were used for variable reduction and evaluation of associations. The total study population included 526 participants aged 50–85; 29% of participants were non-adherent. In the final multivariable model, age (p = 0.02) and Non-Hispanic Black race (p = 0.02) were associated with higher odds of adherence. Factors associated with lower adherence were home rental (vs. ownership) (p = 0.003), perception of low healthcare quality (p = 0.006), no routine checkup within two years (p = 0.002), perceived discrimination (p = 0.02), and nSES deprivation (p = 0.02). After comprehensive variable methods were applied, socioeconomic indicators at the neighborhood and individual level were found to contribute to low CRC screening adherence.

Abstract In this chapter, we focus on mathematical models of tuberculosis epidemiology (TB) that include interactions with HIV and an explicit representation of transmission. We review the natural history of TB and illustrate how its features are simplified and incorporated in mathematical models. We then review the ways HIV influences the natural history of TB, the interventions that have been considered in models, and the way these individual-level effects are represented in models. We then go on to consider population-level effects, reviewing the TB/HIV modelling literature. We first review studies whose focus was on purely epidemiological modelling, and then studies whose focus was on modelling the impact of interventions. We conclude with a summary of the uses and achievements of TB/HIV modelling and some suggested future directions.

Abstract Background Colorectal cancer (CRC) is a leading cause of cancer burden worldwide. In France, it is the second most common cause of cancer death after lung cancer. Systematic uptake of CRC screening can improve survival rates. However, people with limited health literacy (HL) and lower socioeconomic position rarely participate. Our aim is to assess the impact of an intervention combining HL and CRC screening training for general practitioners (GPs) with a pictorial brochure and video targeting eligible patients, to increase CRC screening and other secondary outcomes, after 1 year, in several underserved geographic areas in France. Methods We will use a two-arm multicentric randomized controlled cluster trial with 32 GPs primarily serving underserved populations across four regions in France with 1024 patients recruited. GPs practicing in underserved areas (identified using the European Deprivation Index) will be block-randomized to: 1) a combined intervention (HL and CRC training + brochure and video for eligible patients), or 2) usual care. Patients will be included if they are between 50 and 74 years old, eligible for CRC screening, and present to recruited GPs. The primary outcome is CRC screening uptake after 1 year. Secondary outcomes include increasing knowledge and patient activation. After trial recruitment, we will conduct semi-structured interviews with up to 24 GPs (up to 8 in each region) and up to 48 patients (6 to 12 per region) based on data saturation. We will explore strategies that promote the intervention’s sustained use and rapid implementation using Normalization Process Theory. We will follow a community-based participatory research approach throughout the trial. For the analyses, we will adopt a regression framework for all quantitative data. We will also use exploratory mediation analyses. We will analyze all qualitative data using a framework analysis guided by Normalization Process Theory. Discussion Limited HL and its impact on the general population is a growing public health and policy challenge worldwide. It has received limited attention in France. A combined HL intervention could reduce disparities in CRC screening, increase screening rates among the most vulnerable populations, and increase knowledge and activation (beneficial in the context of repeated screening).

Abstract Background: People suffer from schistosomiasis, leading to liver fibrosis, splenomegaly and thrombocytopenia. The effects of bevacizumab plus oxaliplatin or irinotecan-based chemotherapy regimens on platelets are different, but have not been determined. We conducted a retrospective analysis in metastatic colorectal cancer (mCRC) patients evaluating the impact of bevacizumab on platelet, in order to find a more suitable plan for mCRC patients with a history of schistosomiasis.Methods: The medical records of all mCRC patients with a history of schistosomiasis who received FOLFOX or FOLFIRI with or without bevacizumab from September 1, 2017 to June 30, 2019 in Kunshan Hospital were reviewed. Platelet counts and spleen sizes were compared from the first cycle until completion of chemotherapy.Results: Evaluable splenic enlargement and thrombocytopenia results were obtained from 73 Bevacizumab-treated patients and 80 non-bevacizumab treated patients. In patients treated with oxaliplatin, the rates of splenic enlargement (19.5% vs. 66.7%, P=0.01) and thrombocytopenia (31.7% vs. 77.2%, P=0.02) were lower in the bevacizumab-treated cohort than that in the nonbevacizumab cohort. When stratified for irinotecan, there were no statistical differences of frequency of splenic enlargement between the two groups, however, the rates of thrombocytopenia were higher in the bevacizumab-treated cohort than that in the nonbevacizumab cohort (59.4% vs. 8.7%, P=0.01 ).Conclusion: The bevacizumab plus oxaliplatin-based chemotherapy regimen is more suitable for mCRC patients with a history of schistosomiasis, especially for lower platelet count patients.

Background: Presently, the level of participation in screening programs for colorectal cancer (CRC) with Fecal Immunochemical Test (FIT) is considerably low. Objective: To investigate factors associated with participation in CRC screening using a FIT in the Thai population age 45 to 74 years in the Namphong District of Khon Kaen Province. Materials and Methods: In the present study, the unmatched case-control study design was applied. Three hundred ten participants were equally divided into two groups with 155 participants in the study group and the other 155 in the control group. The data were collected by conducting interviews. Moreover, to explain the association between the factors, multiple logistic regressions were used with adjusted odds ratio (ORadj), a confidence level at 95%, and with p<0.05. Results: It was found that ages were equal to or higher than 60 years (ORadj 2.08; 95%CI 1.19 to 3.63), the lower education level (ORadj 3.70; 95% CI 1.86 to 7.33), a family history of cancer (ORadj 5.25; 95% CI 2.14 to 12.86), receiving advice from public health officials regarding CRC screening (ORadj 3.09; 95% CI 1.81 to 5.27), and high level of knowledge about CRC (ORadj 4.01; 95% CI 2.09 to 7.69) had all been related to participation in the CRC screening program with a statistical significance (p<0.05). Conclusion: The results revealed that receiving advice from public health officials regarding CRC screening and that proper knowledge had been related to participation in screening programs for CRC with the FIT. Thus, to raise awareness and create a greater understanding, public health officers should disseminate knowledge about CRC. Information about the colorectal screening with the FIT should especially be spread to those people who are younger than 60 years of age, have educational levels higher than the primary level, and to those, who have no family history of CRC.

Preventable differences in colorectal cancer (CRC) mortality across racial/ethnic, economic, geographic, and other groups can be eliminated by assuring equitable access and quality across the care continuum, but few interventions have been demonstrated to do so. Multicomponent strategies designed with a health equity framework may be effective. A health equity framework takes into account social determinants of health, multilevel influences (policy, community, delivery, and individual levels), screening processes, and community engagement. Effective strategies for increasing screening uptake include patient navigation and other interventions for structural barriers, reminders and clinical decision support, and data to continuously track metrics and guide targets for improvement. Community resource gaps should be addressed to assure high-quality services irrespective of racial/ethnic and socioeconomic status. One model combines population-based proactive outreach screening with delivery screening at in-person or virtual points of contact, as well as community engagement. Patient- and provider-based behavioral interventions may be considered for increasing screening demand and delivery. Providing a choice of screening tests is recommended for CRC screening, and access to colonoscopy is required for completion of the CRC screening process. Expected final online publication date for the Annual Review of Medicine, Volume 72 is January 27, 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
