Objectives. We sought to determine cardiovascular risk factor prevalence rates among adults in Abu Dhabi, United Arab Emirates. Methods. We used self-reported indicators, anthropometric measures, and blood tests to screen 50 138 adults aged 18 years or older taking part in a population-wide cardiovascular screening program. Results. Participants’ mean age was 36.82 years (SD = 14.3); 43% were men. Risk factor prevalence rates were as follows: obesity, 35%; overweight, 32%; central obesity, 55%; diabetes, 18%; prediabetes, 27%; dyslipidemia, 44%; and hypertension, 23.1%. In addition, 26% of men were smokers, compared with 0.8% of women. Age-standardized diabetes and prediabetes rates were 25% and 30%, respectively, and age-standardized rates of obesity and overweight were 41% and 34%. Conclusions. This population-wide cardiovascular screening program demonstrated a high cardiovascular burden for our small sample in Abu Dhabi. The data form a baseline against which interventions can be implemented and progress monitored as part of the population-wide Abu Dhabi Cardiovascular Disease Program. PMID:21940918

To determine whether our health care employees were undergoing mammography screening according to American Cancer Society guidelines and to determine whether aggressive outreach, education and streamlining of mammography scheduling could improve compliance. All female employees at North Shore University Hospital (NSUH) and several other health system facilities (SF) were sent mailings to their homes that included breast health education and mammography screening guidelines, a questionnaire regarding their own mammography screening history and the opportunity to have their mammography screening scheduled by the Mammography Screening Employee Inreach Program (MSEIP) coordinator. Of the approximately 2,700 female employees aged 40 and over at NSUH and SF, 2,235 (82.7%) responded to the questionnaire, and 1,455 had a mammogram done via the MSEIP. Of the 1,455, 43% either were overdue for a mammogram or had never had one. During a second year of the MSEIP at NSUH and SF, an additional 1,706 mammograms were done. People employed in health care jobs do not necessarily avail themselves of appropriate health care screening. An aggressive program that utilized education, outreach and assistance with scheduling was effective in increasing compliance with mammography screening.

Screening for breast cancer can result in early detection of malignancies and lives saved. Many employers now offer periodic screening as an employee health benefit, and some have established screening programs in the workplace. This study was performed to identify the employer costs of breast cancer screening in the workplace, referrals for suspicious findings, and initial treatment of malignant disease. Additionally, the costs for these same services, had they been obtained outside of a workplace screening program, were estimated. Data on program components and associated costs for an established employer based breast cancer screening program were obtained. These costs were compared to those among a hypothetical cohort of women not enrolled in the workplace screening program. From 1989 through 1995, 1,416 women participated in the program. Nearly 2,500 screening mammograms and approximately 2,773 clinical breast examinations were performed, resulting in 292 referrals to physicians outside of the program for additional diagnostic procedures and treatment as needed. These referrals resulted in the detection of 12 malignancies: 8 Stage I; 3 Stage II; and 1 Stage III. Mammographic and clinical breast examination screening cost $249,041; referrals resulting in benign disease or no detectable disease cost $185,002; and referrals resulting in malignant disease, followed by initial treatment, cost $148,530. Therefore, the total cost was $582,573. Approximately 47% of the cost of referrals and initial treatment were due to employee lost productivity. Total cost in the hypothetical cohort was $1,067,948 under the assumptions that all women received screening outside of the workplace, and that the same number of malignancies were detected at the same stage as in the workplace program. These findings indicate referrals resulting in detection of benign disease or no disease accounted for a substantial proportion of the total cost of the program. In addition, employee lost

Cervical cancer is one of the most common malignancies among women in India. There is a high mortality as patients usually present at an advanced stage because of lack of awareness and nonexistent screening programs. This study was planned to find out awareness about cervical cancer among women and their willingness to utilize screening services in an urban resettlement colony of Delhi, India. A community-based, cross-sectional study was carried out in a resettlement colony of North-West Delhi. Semi-structured interview schedule was used to collect information regarding different aspects of cervical cancer. Analysis was done using SPSS package (SPSS version 16 (UCMS and GTBH, Delhi, India)). A total of 373 women were included in the study. Mean age of study participants was 39.14 years. Two-third of the study population were illiterate. Half of the study population was aware of cervical cancer, and only one-fourth of population were willing to participate in a screening test. Willingness was higher among educated, ever user of family planning method and having knowledge about at least one risk factor, signs or symptoms, or possibility of early diagnosis of cancer cervix. The country's national program advocates for opportunistic and targeted screening of women. An understanding of the factors that influences womens' willingness to participate in screening program is essential for the success of such programs. Hence, this study emphasizes the need for dissemination of knowledge about various aspects of cancer cervix which is critical for uptake of any screening program in a developing country.

We determined the feasibility of abdominal aortic aneurysm (AAA) screening program led by family physicians in public primary healthcare setting using hand-held ultrasound device. The potential study population was 11,214 men aged ≥ 60 years attended by three urban, public primary healthcare centers. Participants were recruited by randomly-selected telephone calls. Ultrasound examinations were performed by four trained family physicians with a hand-held ultrasound device (Vscan®). AAA observed were verified by confirmatory imaging using standard ultrasound or computed tomography. Cardiovascular risk factors were determined. The prevalence of AAA was computed as the sum of previously-known aneurysms, aneurysms detected by the screening program and model-based estimated undiagnosed aneurysms. We screened 1,010 men, with mean age of 71.3 (SD 6.9) years; 995 (98.5%) men had normal aortas and 15 (1.5%) had AAA on Vscan®. Eleven out of 14 AAA-cases (78.6%) had AAA on confirmatory imaging (one patient died). The total prevalence of AAA was 2.49% (95%CI 2.20 to 2.78). The median aortic diameter at diagnosis was 3.5 cm in screened patients and 4.7 cm (p<0.001) in patients in whom AAA was diagnosed incidentally. Multivariate logistic regression analysis identified coronary heart disease (OR = 4.6, 95%CI 1.3 to 15.9) as the independent factor with the highest odds ratio. A screening program led by trained family physicians using hand-held ultrasound was a feasible, safe and reliable tool for the early detection of AAA. PMID:28453577

OBJECTIVES The Northeast Regional Cancer Institute is conducting a program of ongoing epidemiologic research to address cancer disparities in northeast Pennsylvania. Of particular concern are disparities in the incidence of, stage at diagnosis, and mortality from colorectal cancer. In northeast Pennsylvania, age-adjusted incidence and mortality rates for colorectal cancer are higher, and a significantly smaller proportion of new colorectal cancer cases are diagnosed with local stage disease than is observed in comparable national data. Further, estimates of the prevalence of colorectal cancer screening in northeast Pennsylvania are lower than the US average. The Northeast Regional Cancer Institute’s research program supportsmore » surveillance of common cancers, investigations of cancer risk factors and screening behaviors, and the development of resources to further cancer research in this community. This project has the following specific objectives: I. To conduct cancer surveillance in northeast Pennsylvania. a. To monitor incidence and mortality for all common cancers, and colorectal cancer, in particular, and b. To document changes in the stage at diagnosis of colorectal cancer in this high-risk, underserved community. II. To conduct a population-based study of cancer risk factors and screening behavior in a six county region of northeast Pennsylvania. a. To monitor and document changes in colorectal cancer screening rates, and b. To document the prevalence of cancer risk factors (especially factors that increase the risk of colorectal cancer) and to identify those risk factors that are unusually common in this community. APPROACH Cancer surveillance was conducted using data from the Northeast Regional Cancer Institute’s population-based Regional Cancer Registry, the Pennsylvania Cancer Registry, and NCI’s SEER program. For common cancers, incidence and mortality were examined by county within the region and compared to data for similar populations in

This prospective, pre- and post-evaluation of a worksite cardiovascular health management program consisted of employee education, measurement of cardiovascular risk factors, and onsite individual counseling for all employees, along with follow up screening for high risk participants. Of 1,099 employees (16.4% of those eligible) who participated in the initial screening, 596 (54.2%) were classified as high risk. A total of 167 (28.0%) high risk participants completed the 6 month follow up screening. Most high risk participants in the 6 month follow up screening reported they had increased their exercise (64.7%), improved their diet (71.3%), and visited a physician (61.7%). A minority of the participants (16.8%) began new cardiovascular medications, and 2.4% were diagnosed with diabetes. In addition, there were statistically significant decreases in the percentages of participants with elevated systolic blood pressure, diastolic blood pressure, low density lipoprotein cholesterol, and total cholesterol to high density lipoprotein ratio. Almost all (99.7%) of the 909 participants (82.7% of all participants) who completed the satisfaction survey were satisfied or very satisfied with the overall program. Screening in the workplace can identify individuals at high risk for cardiovascular disease. In this study, more than half of the participants were classified as high risk. Most high risk individuals who attended the 6 month follow up screening had improved their cardiovascular health, but attrition remains a challenge for worksite programs.

To develop a low-cost automated video system to effectively screen children aged 6 months to 6 years for amblyogenic factors. In 1994 one of the authors (G.C.) described video vision development assessment, a digitizable analog video-based system combining Brückner pupil red reflex imaging and eccentric photorefraction to screen young children for amblyogenic factors. The images were analyzed manually with this system. We automated the capture of digital video frames and pupil images and applied computer vision and artificial intelligence to analyze and interpret results. The artificial intelligence systems were evaluated by a tenfold testing method. The best system was the decision tree learning approach, which had an accuracy of 77%, compared to the "gold standard" specialist examination with a "refer/do not refer" decision. Criteria for referral were strabismus, including microtropia, and refractive errors and anisometropia considered to be amblyogenic. Eighty-two percent of strabismic individuals were correctly identified. High refractive errors were also correctly identified and referred 90% of the time, as well as significant anisometropia. The program was less correct in identifying more moderate refractive errors, below +5 and less than -7. Although we are pursuing a variety of avenues to improve the accuracy of the automated analysis, the program in its present form provides acceptable cost benefits for detecting ambylogenic factors in children aged 6 months to 6 years.

In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancermore » Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical

Latin America and the Caribbean (LAC) have a significant burden of cervical cancer. Prophylactic human papillomavirus (HPV) vaccines are an opportunity for primary prevention and new screening methods, such as new HPV DNA testing, are promising alternatives to cytology screening that should be analyzed in the context of regional preventive programs. Cytology-based screening programs have not fulfilled their expectations and coverage does not sufficiently explain the lack of impact on screening in LAC. While improved evaluation of screening programs is necessary to increase the impact of screening on the reduction of incidence and mortality, other programmatic aspects will need to be addressed such as follow-up of positive tests and quality control. The implementation of new technologies might enhance screening performance and reduce mortality in the region. The characteristics, performance and impact of cervical cancer screening programs in LAC are reviewed in this article.

Rein, David B.; Wittenborn, John S.; Zhang, Xinzhi; Song, Michael; Saaddine, Jinan B.

2013-01-01

Background To estimate the incremental cost-effectiveness of amblyopia screening at preschool and kindergarten, we compared the costs and benefits of 3 amblyopia screening scenarios to no screening and to each other: (1) acuity/stereopsis (A/S) screening at kindergarten, (2) A/S screening at preschool and kindergarten, and (3) photoscreening at preschool and A/S screening at kindergarten. Methods We programmed a probabilistic microsimulation model of amblyopia natural history and response to treatment with screening costs and outcomes estimated from 2 state programs. We calculated the probability that no screening and each of the 3 interventions were most cost-effective per incremental quality-adjusted life year (QALY) gained and case avoided. Results Assuming a minimal 0.01 utility loss from monocular vision loss, no screening was most cost-effective with a willingness to pay (WTP) of less than $16,000 per QALY gained. A/S screening at kindergarten alone was most cost-effective between a WTP of $17,000 and $21,000. A/S screening at preschool and kindergarten was most cost-effective between a WTP of $22,000 and $75,000, and photoscreening at preschool and A/S screening at kindergarten was most cost-effective at a WTP greater than $75,000. Cost-effectiveness substantially improved when assuming a greater utility loss. All scenarios were cost-effective when assuming a WTP of $10,500 per case of amblyopia cured. Conclusions All 3 screening interventions evaluated are likely to be considered cost-effective relative to many other potential public health programs. The choice of screening option depends on budgetary resources and the value placed on monocular vision loss prevention by funding agencies. PMID:21877675

By comparing the Universal Neonatal Hearing Screening (UNHS) program as implemented in Shanghai and other regions in China and countries around the world, this study makes an assessment of the Shanghai model and summarizes the experiences implementing the UNHS program, so as to provide a valuable reference for other countries or regions to carry out UNHS more effectively. Since Shanghai is one of the most developed regions in China, we also examined the relationship between economic development and the UNHS starting year and coverage rate. The study conducted a systematic review of published studies in Chinese and English on the program status of neonatal hearing screening to compare and analyze the implementation of the UNHS program in 20 cities or provinces in China and 24 regions or countries around the world. The literature search in Chinese was conducted in the three most authoritative publication databases, CNKI (China National Knowledge Infrastructure), WANFANGDATA, and CQVIP (http://www.cqvip.com/). We searched all publications in those databases with the keywords "neonatal hearing screening" (in Chinese) between 2005 and 2014. English literature was searched using the same keywords (in English). The publication database included Medline and Web of Science, and the search time period was 2000-2014. Shanghai was one of the first regions in China to implement UNHS, and its coverage rate was among the top regions by international comparison. The starting time of the UNHS program had no relationship with the Gross Domestic Product (GDP) per capita in the same year. Economic level serves as a threshold for carrying out UNHS but is not a linear contributor to the exact starting time of such a program. The screening coverage rate generally showed a rising trend with the increasing GDP per capita in China, but it had no relationship with the area's GDP per capita in selected regions and countries around the world. The system design of UNHS is the key factor

Methicillin-resistant Staphylococcus aureus (MRSA) poses an increasingly large disease and economic burden worldwide. The effectiveness of screening programs in the tropics is poorly understood. The aims of this study are: (i) to analyze the factors affecting MRSA colonization at admission and acquisition during hospitalization and (ii) to evaluate the cost-effectiveness of a screening program which aims to control MRSA incidence during hospitalization. We conducted a retrospective case-control study of patients admitted to the Communicable Disease Centre (CDC) in Singapore between Jan 2009 and Dec 2010 when there was an ongoing selective screening and isolation program. Risk factors contributing to MRSA colonization on admission and acquisition during hospital stay were evaluated using a logistic regression model. In addition, a cost-effectiveness analysis was conducted to determine the cost per disability-adjusted life year (DALY) averted due to implementing the screening and isolation program. The average prevalence rate of screened patients at admission and the average acquisition rate at discharge during the study period were 12.1 and 4.8 % respectively. Logistic regression models showed that older age (adjusted odds ratio (OR) 1.03, 95 % CI 1.02-1.04, p < 0.001) and dermatological conditions (adjusted OR 1.49, 95 % CI 1.11-1.20, p = 0.008) were independently associated with an increased risk of MRSA colonization at admission. Age (adjusted OR 1.02, 95 % CI 1.01-1.03, p = 0.002) and length of stay in hospital (adjusted OR 1.04, 95 % CI 1.03-1.06, p < 0.001) were independent factors associated with MRSA acquisition during hospitalization. The screening and isolation program reduced the acquisition rate by 1.6 % and was found to be cost saving. For the whole study period, the program cost US$129,916, while it offset hospitalization costs of US$103,869 and loss of productivity costs of US$50,453 with -400 $/DALY averted. This study is the first to our knowledge

Objective We assessed the reliability of a hearing risk factor screening survey used by hearing conservation programs for noise-exposed workers. Design We compared workers’ answers from the screening survey to their answers to a confidential research questionnaire regarding hearing loss risk factors. We calculated kappa statistics to test the correlation between yes/no questions in the research questionnaire compared to answers from one and five years of screening surveys. Study Sample We compared the screening survey and research questionnaire answers of 274 aluminum plant workers. Results Most of the questions in the in-company screening survey showed fair to moderate agreement with the research questionnaire (kappa range: −0.02, 0.57). Workers’ answers to the screening survey had better correlation with the research questionnaire when we compared five years of screening answers. For nearly all questions, workers were more likely to respond affirmatively on the research questionnaire than the screening survey. Conclusions Hearing conservation programs should be aware that workers may underreport hearing loss risk factors and functional hearing status on an audiometric screening survey. Validating company screening tools could help provide more accurate information on hearing loss and risk factors. PMID:27609310

As part of the Meharry Community Networks Program (CNP) needs assessment, a 123-item community survey was administered to assess demographic characteristics, health care access and utilization, and screening practices for various cancers in low-income African Americans. For this study, only African American women 40 years and older (n = 334) were selected from the Meharry CNP community survey database. There were several predictors of breast cancer screening such as marital status and having health insurance (P < .05). Additionally, there were associations between obstacles to screening and geographic region such as transportation and not having enough information about screenings (P < .05). Educational interventions aimed at improving breast cancer knowledge and screening rates should incorporate information about obstacles and predictors to screening.

Lung cancer screening may provide a "teachable moment" for promoting smoking cessation. This study assessed smoking cessation and relapse rates among individuals undergoing follow-up low-dose chest computed tomography (CT) in a clinical CT lung screening program and assessed the influence of initial screening results on smoking behavior. Self-reported smoking status for individuals enrolled in a clinical CT lung screening program undergoing a follow-up CT lung screening exam between 1st February, 2014 and 31st March, 2015 was retrospectively reviewed and compared to self-reported smoking status using a standardized questionnaire at program entry. Point prevalence smoking cessation and relapse rates were calculated across the entire population and compared with exam results. All individuals undergoing screening fulfilled the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology: Lung Cancer Screening v1.2012(®) high-risk criteria and had an order for CT lung screening. A total of 1,483 individuals underwent a follow-up CT lung screening exam during the study interval. Smoking status at time of follow-up exam was available for 1,461/1,483 (98.5%). A total of 46% (678/1,461) were active smokers at program entry. The overall point prevalence smoking cessation and relapse rates were 20.8% and 9.3%, respectively. Prior positive screening exam results were not predictive of smoking cessation (OR 1.092; 95% CI, 0.715-1.693) but were predictive of reduced relapse among former smokers who had stopped smoking for 2 years or less (OR 0.330; 95% CI, 0.143-0.710). Duration of program enrollment was predictive of smoking cessation (OR 0.647; 95% CI, 0.477-0.877). Smoking cessation and relapse rates in a clinical CT lung screening program rates are more favorable than those observed in the general population. Duration of participation in the screening program correlated with increased smoking cessation rates. A positive exam result correlated with reduced

The Internet is a potentially important medium for communication about public health programs including newborn screening. This study explores whether the information available on official newborn screening program websites is consistent with existing guidelines regarding educational content for parents. We conducted a systematic search of the public websites of newborn screening programs in the US and Canada, identifying web pages and downloadable brochures that contained educational information. Two researchers independently reviewed all documents to determine the extent to which they included 14 key recommended educational messages. We identified 85 documents containing educational information on 46 US and 6 Canadian newborn screening program websites. The documents contained from 1 to 14 of the recommended messages. The majority of identified materials emphasized the importance and benefits of screening. The differences between US and Canadian materials were related to the importance of parental involvement in follow-up and issues of consent and storage of blood spots. Our findings are consistent with studies of non-web-based newborn screening education materials. The results emphasize the need for further evaluation of newborn screening education, including internet-based resources, particularly in terms of the impact of particular messages on parental attitudes and behaviors.

After brief training, teachers independently measured visual acuity (VA) in 555 children aged 12-15 years in Ba Ria - Vung Tau Province. Teacher VA measurements were compared to those of refractionists. Sensitivity, specificity, positive predictive value and negative predictive value were calculated for uncorrected VA (UVA) and presenting VA (PVA) 20/40 or worse in either eye. Chi-square, Fisher's exact test and multivariate logistic regression were used to assess factors associated with accuracy of vision screening. Level of significance was set at 5%. Trained teachers in Vietnam demonstrated 86.7% sensitivity, 95.7% specificity, 86.7% positive predictive value and 95.7% negative predictive value in identifying children with visual impairment using the UVA measurement. PVA measurement revealed low accuracy for teachers, which was significantly associated with child's age, sex, spectacle wear and myopic status, but UVA measurement showed no such associations. Better accuracy was achieved in measurement of VA and identification of children with visual impairment using UVA measurement compared to PVA. UVA measurement is recommended for teacher-based vision screening programs.

Purpose To develop a low-cost automated video system to effectively screen children aged 6 months to 6 years for amblyogenic factors. Methods In 1994 one of the authors (G.C.) described video vision development assessment, a digitizable analog video-based system combining Brückner pupil red reflex imaging and eccentric photorefraction to screen young children for amblyogenic factors. The images were analyzed manually with this system. We automated the capture of digital video frames and pupil images and applied computer vision and artificial intelligence to analyze and interpret results. The artificial intelligence systems were evaluated by a tenfold testing method. Results The best system was the decision tree learning approach, which had an accuracy of 77%, compared to the “gold standard” specialist examination with a “refer/do not refer” decision. Criteria for referral were strabismus, including microtropia, and refractive errors and anisometropia considered to be amblyogenic. Eighty-two percent of strabismic individuals were correctly identified. High refractive errors were also correctly identified and referred 90% of the time, as well as significant anisometropia. The program was less correct in identifying more moderate refractive errors, below +5 and less than −7. Conclusions Although we are pursuing a variety of avenues to improve the accuracy of the automated analysis, the program in its present form provides acceptable cost benefits for detecting ambylogenic factors in children aged 6 months to 6 years.

Cancer screening is a process of care consisting of several steps and interfaces. This article reviews what is known about the association between organizational factors and cancer screening rates and examines how organizational strategies can address the steps and interfaces of cancer screening in the context of both intraorganizational and interorganizational processes. We reviewed 79 studies assessing the relationship between organizational factors and cancer screening. Screening rates are largely driven by strategies to 1) limit the number of interfaces across organizational boundaries; 2) recruit patients, promote referrals, and facilitate appointment scheduling; and 3) promote continuous patient care. Optimal screening rates can be achieved when health-care organizations tailor strategies to the steps and interfaces in the cancer screening process that are most critical for their organizations, the providers who work within them, and the patients they serve.

Worldwide, colorectal cancer is the fourth leading cause of death from cancer and the incidence is projected to increase. Many countries are exploring the introduction of organized screening programs, but there is limited information on the resources required and guidance for cost-effective implementation. To facilitate the generating of the economics evidence base for program implementation, we collected and analyzed detailed program cost data from 5 European members of the International Colorectal Cancer Screening Network. The cost per person screened estimates, often used to compare across programs as an overall measure, varied significantly across the programs. In addition, there were substantial differences in the programmatic and clinical cost incurred, even when the same type of screening test was used. Based on these findings, several recommendations are provided to enhance the underlying methodology and validity of the comparative economic assessments. The recommendations include the need for detailed activity-based cost information, the use of a comprehensive set of effectiveness measures to adequately capture differences between programs, and the incorporation of data from multiple programs in cost-effectiveness models to increase generalizability. Economic evaluation of real-world colorectal cancer-screening programs is essential to derive valuable insights to improve program operations and ensure optimal use of available resources.

South Asian Canadians experience disproportionately high rates of cardiovascular disease (CVD). The goal of this qualitative study was to determine the feasibility of implementing a sustainable, culturally adapted, community-based CVD risk factor screening program for this population. South Asians (≥ 45 years) in Calgary, Alberta underwent opportunistic cardiovascular risk factor screening by lay trained volunteers at local religious facilities. Those with elevated blood pressure (BP) or ≥ 1 risk factor underwent point of care cholesterol testing, 10-year CVD risk calculation, counseling, and referral to family physicians and local culturally tailored chronic disease management (CDM) programs. Participants were invited for re-screening and were surveyed about health system follow-up, satisfaction with the program and suggestions for improvement. Changes in risk factors from baseline were estimated using McNemar's test (proportions) and paired t-tests (continuous measures). Baseline assessment was completed for 238 participants (median age 64 years, 51% female). Mean TC, HDL and TC/HDL were 5.41 mmol/L, 1.12 mmol/L and 4.7, respectively. Mean systolic and diastolic blood pressures (mmHg) were 129 and 75 respectively. Blood pressure and TC/HDL ratios exceeded recommended targets in 36% and 58%, respectively, and 76% were at high risk for CVD. Ninety-nine participants (47% female) attended re-screening. 82% had accessed health care providers, 22% reported medication changes and 3.5% had attended the CDM programs. While BP remained unchanged, TC and TC/HDL decreased and HDL increased significantly (mean differences: -0.52 mmol/L, -1.04 and +0.07 mmol/L, respectively). Participants were very satisfied (80%) or satisfied (20%) with the project. Participants suggested screening sessions and CDM programs be more accessible by: delivering evening or weekends programs at more sites, providing transportation, offering multilingual programs/translation assistance, reducing

To examine women's preferences for characteristics of chlamydia screening. Chlamydia trachomatis is the most common curable sexually transmitted disease. To design effective screening programs, it is important to fully capture the benefits of screening to patients. Thus, the value of experience factors must be considered alongside health outcomes. A self-complete discrete choice experiment questionnaire was administered to women attending a family planning clinic. Chlamydia screening was described by five characteristics: location of screening; type of screening test; cost of screening test; risk of developing pelvic inflammatory disease if chlamydia is untreated; and support provided when receiving results. One hundred twenty-six women completed the questionnaire. Respondents valued characteristics of the care experience. Screening was valued at 15 pound; less invasive screening tests increase willingness to pay by 7 pound, and more invasive tests reduce willingness to pay by 3.50 pound. The most preferred screening location was the family planning clinic, valued at 5 pound. The support of a trained health-care professional when receiving results was valued at 4 pound. Respondents under 25 years and those in a casual relationship were less likely to be screened. Women valued experience factors in the provision of chlamydia screening. To correctly value these screening programs and to predict uptake, cost-effectiveness studies should take such values into account. Failure to do this may result in incorrect policy recommendations.

Colorectal cancer (CRC) is a leading cause of cancer death in the United States. Early detection through recommended screening has been shown to have favorable treatment outcomes, yet screening rates among the medically underserved and uninsured are low, particularly for rural and minority populations. This study evaluated the effectiveness of a patient navigation program that addresses individual and systemic barriers to CRC screening for patients at rural, federally qualified community health centers. This quasi-experimental evaluation compared low-income patients at average risk for CRC (n = 809) from 4 intervention clinics and 9 comparison clinics. We abstracted medical chart data on patient demographics, CRC history and risk factors, and CRC screening referrals and examinations. Outcomes of interest were colonoscopy referral and examination during the study period and being compliant with recommended screening guidelines at the end of the study period. We conducted multilevel logistic analyses to evaluate the program's effectiveness. Patients at intervention clinics were significantly more likely than patients at comparison clinics to undergo colonoscopy screening (35% versus 7%, odds ratio = 7.9, P < .01) and be guideline-compliant on at least one CRC screening test (43% versus 11%, odds ratio = 5.9, P < .001). Patient navigation, delivered through the Community Cancer Screening Program, can be an effective approach to ensure that lifesaving, preventive health screenings are provided to low-income adults in a rural setting.

The effectiveness of a CNS-led community-based COPD screening and intervention program.

DeJong, Sandra R; Veltman, Rebecca H

The purpose of this study was to evaluate the effectiveness of a screening program in identifying undiagnosed individuals with chronic obstructive pulmonary disease (COPD). THEORETICAL RATIONALE: Underdiagnosis of COPD is common. Symptoms do not usually become apparent until the disease is advanced. Consequently, by the time a diagnosis of COPD is made, based on symptoms, the individual has often lost up to 50% or more of their original lung capacity. Early diagnosis and intervention has been demonstrated to have an impact in slowing the progression of the disease. The study was based on the premise that when individuals become self-aware of their risk factors related to disease, they are more likely to change their behaviors. The Transtheoretical Model describes how individuals move through various stages of change and how they can be helped in transitioning from one stage to another. Subjects (n = 243) were recruited via letter, newspaper, and physician referral. The screening program consisted of (1) pulmonary function testing using a handheld spirometry device, (2) education about the test results and COPD, and (3) smoking cessation counseling. Current smokers and those found to have obstruction were contacted at 8 to 12 weeks after screening. Results indicated that 209 (86%) of participants were at risk for developing COPD as evidenced by current or past smoking status. Mild to moderate stage obstructive disease was found in 55 subjects (23%). Of 61 subjects contacted after the screening, 29 smokers (47%) indicated they had stopped smoking, were in the process of quitting, or were seriously considering quitting. Results support the use of a community-screening program to identify and help modify risk factors for COPD. IMPLICATIONS FOR NURSING PRACTICES: This project provides an example of how a clinical nurse specialist (CNS) can exercise all the spheres of CNS influence: the patient/client sphere, the nursing personnel sphere, and the organization sphere.

Cervical cancer has long been known as a preventable disease. Yet it still is a prime women's health issue globally. In Malaysia, the current cervical cancer screening program, introduced in the 1960s, has been found to be unsuccessful in terms of Pap smear coverage. The aim of this study is to determine providers perceptives on the program and the feasibility of practicing an organized cervical screening program in Malaysia. 11 key informant interviews were conducted with policy makers and health care providers from the Ministry of Health in Malaysia from October 2009 to May 2010. Interviewees' perceptions were explored on current and organized cervical screening program based on their expertise and experience. The results highlighted that the existing cervical screening program in Malaysia faced flaws at all levels that failed to reduce cervical cancer morbidity and mortality. The identified weaknesses were poor acceptance by women, lack of commitment by health care providers, nature of the program, an improper follow-up system, limited resources and other competing needs. Complementarily, all interviewees perceived an organized cervical screening program as an alternative approach both feasible and acceptable by women and government to practice in Malaysia. Better screening coverage depends on an effective screening program that incorporates a behaviour-based strategy. A new program should be focused in the policy-making context to improve screening coverage and to effectively combat cervical cancer.

Cervical cancer screening: A never-ending developing program

With the term “oncological screening”, we define the overall performances made to detect early onset of tumors. These tests are conducted on a population that does not have any signs or symptoms related to a neoplasm. The whole population above a certain age, only one sex, only subjects with a high risk of developing cancer due to genetic, professional, discretionary reasons may be involved. Screening campaigns should be associated, when risk factors that can be avoided are known, with campaigns for the prevention of cancer by means of suitable behavior. The goal of cancer screening cannot however be limited to the diagnosis of a greater number of neoplasms. Screening will be useful only if it leads to a reduction in overall mortality or at least in mortality related to the tumor. Screening should then allow the diagnosis of the disease at a stage when there is a possibility of healing, possibility that is instead difficult when the disease is diagnosed at the appearance of signs or symptoms. This is the reason why not all campaigns of cancer screening have the same effectiveness. In Italy, every year there are about 150000 deaths due to cancer. Some of these tumors can be cured with a very high percentage of success if diagnosed in time. Cervical cancer can be diagnosed with non-invasive tests. The screening test used all over the world is Papanicolaou (Pap) test. This test may be carried out over the entire healthy population potentially exposed to the risk of contracting cancer. Public health has begun the screening campaigns in the hope of saving many of the approximately 270000 new cases of cancer reported each year. Screening is done following protocols that guarantee quality at the national level: these protocols are subject to change over time to reflect new realities or to correct any errors in the system. A simplified sketch of a possible route of cancer screening is as follows: (1) after selecting the target population, for example all women between

Incidence-based evaluations of cervical cancer screening programs have suggested age-specific impacts and there is uncertainty regarding the effectiveness of screening outside the ages of 30-60 years. We audited the screening histories of cervical cancer deaths and conducted a case-control evaluation of the effectiveness of organized screening in different ages with mortality as outcome. We included all 506 cervical cancer deaths in Finland in 2000-2009 due to cancers diagnosed in 1990 or later, and 3,036 controls matched by age at diagnosis to the cases. Squamous cell carcinoma constituted 59% of the cases, adenocarcinomas 29%, and the remaining 12% were other specified and unspecified cervical malignancies. Most deaths (54%) were due to cancers diagnosed more than 5 years after last screening invitation, 24% were diagnosed among nonattenders and only 14% of deaths occurred among women who had attended invitational screening. The risk reduction associated with attending a single program screen at an age below 40 was nonsignificant (OR 0.70; 95% CI 0.33-1.48), while clear risk reductions were observed after screening at the age of 40-54 (OR 0.33; CI 0.20-0.56) and 55-69 (OR 0.29; CI 0.16-0.54). This study also provides some indication of a long-lasting additional effect of screening at the age of 65. Possible avenues for improving the effectiveness of the Finnish screening program include efforts to increase attendance and an extension of the target ages to include 65-to 69-year-old women. The potential benefit of increasing the sensitivity of the screening test or shortening the screening interval is smaller. Copyright © 2012 UICC.

The effectiveness of breast cancer screening programs in reducing mortality is well established in the scientific literature. The National Breast Cancer Screening Program in Israel provides biennial mammograms for women of average risk aged 50-74 and annual mammograms for women aged 40-49 at higher risk. Compliance is high, but differential. This study explores different factors associated with breast cancer screening attendance among women aged 40-74 years. Two main outcomes were studied: ever been screened and been screened in the 2 years preceding the study, using the cross-sectional Knowledge, Attitudes and Practices (KAP) Survey conducted in 2010-2012 among 2575 Israeli women aged 21+ years. The independent variables were sociodemographic characteristics, perceived health status, lifestyle habits, and healthcare fund membership. Bivariate and multivariable logistic regressions were conducted. Of the 943 participants aged 50-74, 87% had ever been screened and 74.8% had attended screening for breast cancer in the last 2 years. In multivariable models, Jewish compared to Arab women (adjusted prevalence ratio [APR] = 2.09, 95% confidence interval [CI]: 1.02-4.32), and unmarried compared to married women (APR = 2.9, 95% CI: 1.2-7.2), were more likely to have ever been screened. The only factor associated with breast cancer screening in the 2 years preceding the study was healthcare fund membership. In women aged 40-49 years, ethnicity was the only contributing factor associated with breast cancer screening, with higher screening rates in the 2 years preceding the study in Jewish versus Arab women (APR = 3.7, 95% CI: 1.52-9.3). Breast cancer screening attendance in Israel is high. However, significant differences are observed by membership of healthcare fund and by ethnicity, calling for better targeted outreach programs at this level.

To determine the impact of applying an age cutoff to tumor-based Lynch syndrome (LS) screening, specifically focusing on changes in relative effectiveness, efficiency, and cost. The project was undertaken to answer questions about implementation of the LS screening program in an integrated health care delivery system. Clinical data extracted from an internal cancer registry, previous modeling efforts, published literature, and gray data were used to populate decision models designed to answer questions about the impact of age cutoffs in LS screening. Patients with colorectal cancer (CRC) were stratified at 10-year intervals from ages 50 to 80 years and compared with no age cutoff. Outcomes are reported for a cohort of 325 patients screened and includes total cost to screen, LS cases present in the cutoff category, number of LS cases expected to be identified by screening, cost per LS case detected, and total number and percentage of LS cases missed. Applying an age cutoff to an LS screening program has considerable potential for decreasing total screening costs and increasing efficiency, but at a loss of effectiveness. Imposing an age cutoff of 50 years reduces the cost of the screening program to 16% of a program with no age cutoff, but at the expense of missing more than half of the cases. Failure to identify LS cases is magnified by a cascade effect in family members. The results of this analysis influenced the final policy in our system.

The fecal immunochemical test (FIT) has been widely used in preliminary screening for colorectal cancer (CRC). The high-risk factor questionnaire (HRFQ) and quantitative risk-assessment method (QRAM) are recommended for estimating the risk of CRC qualitatively and quantitatively in China. We aimed to prospectively compare the diagnostic values of CRC preliminary screening methods to identify which method is preferable as a screening strategy. Individuals aged 40-74 years old were enrolled in a mass CRC screening program from January 1, 2007 to December 31, 2014, in Jiashan County, Zhejiang Province, China. FIT of two stool specimens at 1-week intervals was performed by laboratory personnel and face-to-face interviews were conducted by trained investigators. Screening data in the program were linked to a CRC surveillance and registry system, and CRC cases reported in the system were regarded as true patients. A total of 96,043 subjects were included. The sensitivity and specificity of FIT for detecting CRC cases were 75.49% (95% CI 69.84-80.39) and 90.36% (95% CI 90.17-90.54), respectively. QRAM was more sensitive (p < 0.001) and less specific (p < 0.001) than HRFQ. The sensitivity and specificity of FIT along with HRFQ were 86.56% (95% CI 81.81-90.22) and 81.37% (95% CI 81.12-81.62), and those of FIT along with QRAM were 88.93% (95% CI 84.47-92.23) and 73.95% (95% CI 73.67-74.23). Our findings suggest that CRC preliminary screening with FIT and QRAM in parallel has high sensitivity and satisfactory specificity, and is a useful strategy in mass screening programs.

Objective: To evaluate the cost-effectiveness of colorectal cancer screening program in different age groups from the view of health economics. Methods: The screening compliance rates, detection rates in different age groups were calculated by using the data from colorectal cancer screening program in Jiashan county, Zhejiang province. The differences in indicator among age groups were analyzed with χ (2) test or trend χ (2) test. The ratios of cost to the number of case were calculated according to cost statistics. Results: The detection rates of immunochemical fecal occult blood test (iFOBT) positivity, advanced adenoma and colorectal cancer and early stage cancer increased with age, while the early diagnosis rates were negatively associated with age. After exclusion the younger counterpart, the cost-effectiveness of individuals aged >50 years could be reduced by 15 %- 30 % . Conclusion: From health economic perspective, it is beneficial to start colorectal cancer screening at age of 50 years to improve the efficiency of the screening.

Financing for newborn screening is different from virtually all other public health programs. All except 5 screening programs collect fees as the primary source of program funding. A fee-based approach to financing newborn screening has been adopted by most states, to ensure consistent funding for this critical public health activity. Two types of data are reported here, ie, primary data from a survey of 37 state public health agencies and findings from exploratory case studies from 7 states. Most of the programs that participated in this survey (73%) reported that their newborn screening funding increased between 2002 and 2005, typically through increased fees and to a lesser extent through Medicaid, Title V Maternal and Child Health Services Block Grant, and state general revenue funding. All of the responding states that collect fees (n = 31) use such funds to support laboratory expenses, and most (70%) finance short-term follow-up services and program management. Nearly one half (47%) finance longer-term follow-up services, case management, or family support beyond diagnosis. Other states (43%) finance genetic or nutritional counseling and formula foods or treatment. Regardless of the source of funds, the available evidence indicates that states are committed to maintaining their programs and securing the necessary financing for the initial screening through diagnosis. Use of federal funding is currently limited; however, pressure to provide dedicated federal funding would likely increase if national recommendations for a uniform newborn screening panel were issued.

Since 1998, after we started the support group for neonatal hearing screening, many other hearing screening programs were held in Brazil. In Alagoas, the first program started in 2003, but none of its results were published. Hearing is paramount for human communication; therefore, childhood hearing loss can impair speech acquisition, emotional, educational and social development. to present the results achieved in a neonatal hearing screening program in Maceió. a retrospective analytical study was carried out in order to study the results from tests carried out from September 2003 to December 2006 in a private hospital of Maceió. from a total of 2002 newborns, 1,626 fitted the inclusion criteria, 835 (51.4%) males. The hearing screening was considered appropriate in 1416 cases (87.1%), and the most frequently found age was between 16 and 30 days. Finally, 163 (10.0%) children presented risk indicators for hearing loss, and hyperbilirubinemia was the most common indicator. statistical results obtained from this hearing screening program show the importance of holding such programs. This study is important because it contributes to further regional or multinational studies.

There is a general consensus on the recommendation of applying breast cancer screening programs to the population. In March 1990, the Health Department set in motion a Program for the Early Detection of Breast Cancer, with the aim of reducing mortality due to this tumour. At present, the program is reaching the end of its seventh round. The present study aims to analyze the results obtained, describing the principal indicators of the process and the impact predictions according to the most determinant factors. Data was collected for the screening explorations carried out from the start of the program up until December 31st 2002; the data was classified according to age at the time of exploration, type of exploration and round. During the period, 354,575 explorations were carried out. Process indicators: an additional exploration was recommended for 11.22% of the women. Naught point sixty seven percent (0.67%) of the women were sent to hospital units for a diagnostic evaluation. A malignant tumour was confirmed in 0.34% of the women subjected to exploration. It was recommended that 8.37% of the women should carry out an intermediate exploration before the next call from the screening program. Predictive impact indicators: global recruitment was 88.68%; global participation 87.91%; and adherence to the program was 96.32%. The rate of detection reached the figure of 3.95 per 1,000 women explored. Of the tumours detected: 19.17% were intraductal and 37.23% of the invasive tumours had a size equal to or below 10mm. Seventy-four point eighty nine percent (74.89%) of total tumours did not show ganglionary invasion. Considering the references established by the European Union for screening programs, all of the calculated predictive indicators exceed the required standards.

To describe the cultural, social and gender features that determine attitudes to colorectal cancer screening in a target group of patients aged 50 to 69 years old in the primary health care setting. We performed a qualitative ethnographic study from a gender perspective. Participants consisted of men and women aged 50 to 69 years old in the Balearic Islands and Barcelona. Group discussion and a field diary were used. The key element was diagnosis at an early stage. Until recently, cancer was considered an incurable disease but is currently perceived as a serious health problem that can be cured if diagnosed promptly. The participants requested more information on cancer and felt they were at risk, mainly because of their age. Men tended to pay attention to symptoms while women tended to ignore them. Attitudes to colorectal cancer screening were generally positive, even to colonoscopy. Some barriers to screening were identified in women, such as a fear of having cancer. The opportunity for early diagnosis is the key element in promoting participation in a colorectal cancer screening program. Perceptions-and hence willingness to participate in screening-differ between men and women. Factors to be taken into account in the design of population-based colorectal cancer programs are health concerns in men and fear of a cancer diagnosis in women. Copyright © 2012 SESPAS.

Evidence-based guidelines recommend that all newly diagnosed colon cancer be screened for Lynch syndrome (LS), but best practices for implementing universal tumor screening have not been extensively studied. We interviewed a range of stakeholders in an integrated health-care system to identify initial factors that might promote or hinder the successful implementation of a universal LS screening program. We conducted interviews with health-plan leaders, managers, and staff. Interviews were audio-recorded and transcribed. Thematic analysis began with a grounded approach and was also guided by the Practical Robust Implementation and Sustainability Model (PRISM). We completed 14 interviews with leaders/managers and staff representing involved clinical and health-plan departments. Although stakeholders supported the concept of universal screening, they identified several internal (organizational) and external (environment) factors that promote or hinder implementation. Facilitating factors included perceived benefits of screening for patients and organization, collaboration between departments, and availability of organizational resources. Barriers were also identified, including: lack of awareness of guidelines, lack of guideline clarity, staffing and program "ownership" concerns, and cost uncertainties. Analysis also revealed nine important infrastructure-type considerations for successful implementation. We found that clinical, laboratory, and administrative departments supported universal tumor screening for LS. Requirements for successful implementation may include interdepartmental collaboration and communication, patient and provider/staff education, and significant infrastructure and resource support related to laboratory processing and systems for electronic ordering and tracking.

To test a multimedia patient education program on colorectal cancer (CRC) screening that was designed specifically for the Hispanic/Latino community, and developed with input from community members. A total of 270 Hispanic/Latino adults, age 50-80 years, participated in Spanish for all phases of this pretest-posttest design. Patients were randomly assigned to a version of the multimedia program that opened with either a positive or negative introductory appeal. Structured interviews assessed screening relevant knowledge (anatomy and key terms, screening options, and risk information), past screening behavior, willingness to consider screening options, intention to discuss CRC screening with the doctor, and reactions to the multimedia patient education program. The multimedia program significantly increased knowledge of anatomy and key terms (e.g., polyp), primary screening options (FOBT, flexible sigmoidoscopy, colonoscopy), and risk information as well as willingness to consider screening (p<.001 for all). No significant differences emerged between positive and negative introductory appeals on these measures, intention to discuss CRC screening with their doctor, or rating the multimedia program. Multimedia tools developed with community input that are designed to present important health messages using graphics and audio can reach Hispanic/Latino adults across literacy levels and ethnic backgrounds. Additional research is needed to determine effects on actual screening behavior. Despite promising results for engaging a difficult-to-reach audience, the multimedia program should not be considered a stand-alone intervention or a substitute for communication with physicians. Rather, it is a priming mechanism intended to prepare patients for productive discussions of CRC screening.

IMPORTANCE Newborn screening for severe combined immunodeficiency (SCID) using assays to detect T-cell receptor excision circles (TRECs) began in Wisconsin in 2008, and SCID was added to the national recommended uniform panel for newborn screened disorders in 2010. Currently 23 states, the District of Columbia, and the Navajo Nation conduct population-wide newborn screening for SCID. The incidence of SCID is estimated at 1 in 100 000 births. OBJECTIVES To present data from a spectrum of SCID newborn screening programs, establish population-based incidence for SCID and other conditions with T-cell lymphopenia, and document early institution of effective treatments. DESIGN Epidemiological and retrospective observational study. SETTING Representatives in states conducting SCID newborn screening were invited to submit their SCID screening algorithms, test performance data, and deidentified clinical and laboratory information regarding infants screened and cases with nonnormal results. Infants born from the start of each participating program from January 2008 through the most recent evaluable date prior to July 2013 were included. Representatives from 10 states plus the Navajo Area Indian Health Service contributed data from 3 030 083 newborns screened with a TREC test. MAIN OUTCOMES AND MEASURES Infants with SCID and other diagnoses of T-cell lymphopenia were classified. Incidence and, where possible, etiologies were determined. Interventions and survival were tracked. RESULTS Screening detected 52 cases of typical SCID, leaky SCID, and Omenn syndrome, affecting 1 in 58 000 infants (95%CI, 1/46 000-1/80 000). Survival of SCID-affected infants through their diagnosis and immune reconstitution was 87%(45/52), 92%(45/49) for infants who received transplantation, enzyme replacement, and/or gene therapy. Additional interventions for SCID and non-SCID T-cell lymphopenia included immunoglobulin infusions, preventive antibiotics, and avoidance of live vaccines. Variations in

Mailed questionnaires were used to examine the success of PKU (phenylketonuria) screening programs that were operated by departments of health and to examine differences between these programs. Of 55 departments, 44 were returned and 42 departments reported they had a PKU detection program. Thirty-eight respondents considered the PKU detection program to be effective, and 31 respondents indicated that the entire program cost $60,000 or less per year. The answers and comments on the questionnaires showed a generally positive view of the effectiveness about the value of the treatment program in general were also positive. However, a few departments indicated that more clinical evidence and experience were needed to fully evaluate the overall merits of PKU detection and screening programs. PMID:803697

Key considerations in designing a patient navigation program for colorectal cancer screening.

2014-07-01

Colorectal cancer is the second leading cause of cancer mortality among those cancers affecting both men and women. Screening is known to reduce mortality by detecting cancer early and through colonoscopy, removing precancerous polyps. Only 58.6% of adults are currently up-to-date with colorectal cancer screening by any method. Patient navigation shows promise in increasing adherence to colorectal cancer screening and reducing health disparities; however, it is a complex intervention that is operationalized differently across institutions. This article describes 10 key considerations in designing a patient navigation intervention for colorectal cancer screening based on a literature review and environmental scan. Factors include (1) identifying a theoretical framework and setting program goals, (2) specifying community characteristics, (3) establishing the point(s) of intervention within the cancer continuum, (4) determining the setting in which navigation services are provided, (5) identifying the range of services offered and patient navigator responsibilities, (6) determining the background and qualifications of navigators, (7) selecting the method of communications between patients and navigators, (8) designing the navigator training, (9) defining oversight and supervision for the navigators, and (10) evaluating patient navigation. Public health practitioners can benefit from the practical perspective offered here for designing patient navigation programs. © 2013 Society for Public Health Education.

A Network and Visual Quality Aware N-Screen Content Recommender System Using Joint Matrix Factorization

PubMed Central

Ullah, Farman; Sarwar, Ghulam; Lee, Sungchang

2014-01-01

We propose a network and visual quality aware N-Screen content recommender system. N-Screen provides more ways than ever before to access multimedia content through multiple devices and heterogeneous access networks. The heterogeneity of devices and access networks present new questions of QoS (quality of service) in the realm of user experience with content. We propose, a recommender system that ensures a better visual quality on user's N-screen devices and the efficient utilization of available access network bandwidth with user preferences. The proposed system estimates the available bandwidth and visual quality on users N-Screen devices and integrates it with users preferences and contents genre information to personalize his N-Screen content. The objective is to recommend content that the user's N-Screen device and access network are capable of displaying and streaming with the user preferences that have not been supported in existing systems. Furthermore, we suggest a joint matrix factorization approach to jointly factorize the users rating matrix with the users N-Screen device similarity and program genres similarity. Finally, the experimental results show that we also enhance the prediction and recommendation accuracy, sparsity, and cold start issues. PMID:24982999

Objective: From an actual cancer screening service demanders' perspective, we tried to understand the preference on screening frequency and willingness-to-pay for the packaging screening program on common cancers and to evaluate its long-term sustainability in urban populations in China. Methods: From 2012 to 2014, a multi-center cross-sectional survey was conducted among the actual screening participants from 13 provinces covered by the Cancer Screening Program in Urban China (CanSPUC). By face-to-face interview, information regarding to preference to screening frequency, willingness-to-pay for packaging screening program, maximum amount on payment and related reasons for unwillingness were investigated. Results: A total of 31 029 participants were included in this survey, with an average age as (55.2±7.5) years and median annual income per family as 25 000 Chinese Yuan. People's preference to screening frequency varied under different assumptions ( " totally free" and "self-paid" ). When the packaging screening was assumed totally free, 93.9% of residents would prefer to take the screening program every 1 to 3 years. However, the corresponding proportion dropped to 67.3% when assuming a self-paid pattern. 76.7% of the participants had the willingness-to-pay for the packaging screening, but only 11.2% of them would like to pay more than 500 Chinese Yuan (the expenditure of the particular packaging screening were about 1 500 Chinese Yuan). The remaining 23.3% of residents showed no willingness-to-pay, and the main reasons were unaffordable expenditure (71.7%) and feeling'no need'(40.4%). Conclusions: People who participated in the CanSPUC program generally tended to choose high-frequency packaging screening program, indicating the high potential acceptance for scale-up packaging screening, while it needs cautious assessments and rational guidance to the public. Although about seven in ten of the residents were willing to pay, the payment amount was limited

The resolution of policy questions relating to medical genetic screening programs will not be without considerable difficulty. Examples include such issues as the optimal degree of screening program expansion, the relative values of screening for different genetic diseases, the appropriate sources of program funding (public vs. private), and the relative value of funding expanded genetic screening programs vs. research directed toward elimination of genetic traits themselves. Information on the net impact of the relevant alternatives is greatly needed, and this need will increase if the National Genetics Act receives funding approval. We have provided what is hopefully a contribution toward this end. While our analysis pertains to a specific disease and a specific screening program for that disease, the methodology is readily generalizable to other genetic diseases, as well as programs of any size or structure. Hopefully, this will serve to stimulate further research efforts that we believe are needed for the objective consideration of resource allocation alternatives. PMID:418675

Approximately 15% to 25% of colorectal cancer (CRC) cases have positive family history for disease. Colonoscopy screening test is the best way for prevention and early diagnosis. Studies have found that first degree relatives (FDRs) with low socioeconomic status are less likely to participate in colonoscopy screening program. The aim of this study is to determine the association between socioeconomic status and participation in colonoscopy screening program in FDRs. This descriptive cross-sectional, study has been conducted on 200 FDRs who were consulted for undergoing colonoscopy screening program between 2007 and 2013 in research institute for gastroenterology and liver disease of Shahid Beheshti University of Medical Sciences, Tehran, Iran. They were interviewed via phone by a valid questionnaire about socioeconomic status. For data analysis, chi-square, exact fisher and multiple logistic regression were executed by SPSS 19. The results indicated 58.5% participants underwent colonoscopy screening test at least once to the time of the interview. There was not an association between participation in colonoscopy screening program and socioeconomic status to the time of the interview in binomial analysis. But statistical significance between intention to participate and educational and income level were found. We found, in logistic regression analysis, that high educational level (Diploma and University degree in this survey) was a predictor to participate in colonoscopy screening program in FDRs. According to this survey low socioeconomic status is an important factor to hinder participation of FDRs in colonoscopy screening program. Therefore, planned interventions for elevation knowledge and attitude in FDRs with low educational level are necessary. Also, reducing colonoscopy test costs should be a major priority for policy makers.

Cervical screening programs are highly protective for cervical cancer, but only for women attending screening procedure. Identify socio-economic and demographic determinants for non-attendance in cervical screening. Design: Population-based case-control study. Setting: Sweden. Population: Source population was all women eligible for screening. Based on complete screening records, two groups of women aged 30-60 were compared. The case group, non-attending women, (N = 314,302) had no smear registered for 6-8 years. The control group (N = 266,706) attended within 90 days of invitation. Main outcome measures: Risk of non-attendance by 9 groups of socioeconomic and demographic variables. Analysis: Unadjusted odds ratios (OR) and OR after adjustment for all variables in logistic regression models were calculated. Women with low disposable family income (adjOR 2.06; 95% confidence interval (CI) 2.01-2.11), with low education (adjOR 1.77; CI 1.73-1.81) and not cohabiting (adjOR 1.47; CI 1.45-1.50) were more likely to not attend cervical screening. Other important factors for non-attendance were being outside the labour force and receiving welfare benefits. Swedish counties are responsible for running screening programs; adjusted OR for non-participation in counties ranged from OR 4.21 (CI 4.06-4.35) to OR 0.54 (CI 0.52-0.57), compared to the reference county. Being born outside Sweden was a risk factor for non-attendance in the unadjusted analysis but this disappeared in certain large groups after adjustment for socioeconomic factors. County of residence and socio-economic factors were strongly associated with lower attendance in cervical screening, while being born in another country was of less importance. This indicates considerable potential for improvement of cervical screening attendance in several areas if best practice of routines is adopted.

The Manitoba Perinatal Screening Program is guided by a committee of medical specialists with skills in the diagnosis and management of disorders of metabolism in the newborn. The program is voluntary and is centralized at Cadham Provincial Laboratory, in Winnipeg. A filter card blood specimen is collected from newborns on discharge from hospital, and a filter card urine sample is collected and mailed to the laboratory by the mother when the infant is about 2 weeks of age. The overall compliance rates for the blood and urine specimens are approximately 100% and 84% respectively. The blood specimen is screened for phenylalanine and other amino acids, thyroxine, galactose, galactose-1-phosphate and biotinidase. The urine specimen is screened for amino acids, including cystine, as well as methylmalonic acid and homocystine. Between 1965 and 1985, 83 cases of metabolic disorders were detected, including 23 cases of primary hypothyroidism, 14 of classic phenylketonuria, 5 of galactosemia variants, 3 of galactosemia, 2 of maple syrup urine disease and 1 of hereditary tyrosinemia. The direct cost per infant screened is $5.50, and the cost:benefit ratio is approximately 7.5:1. Maternal serum alpha-fetoprotein screening is being made available as the necessary supporting clinical facilities become available. On the basis of this experience, the author outlines the components that are important for an effective screening program. PMID:3676929

Background Interval cancers are primary breast cancers diagnosed in women after a negative screening test and before the next screening invitation. Our aim was to evaluate risk factors for interval cancer and their subtypes and to compare the risk factors identified with those associated with incident screen-detected cancers. Methods We analyzed data from 645,764 women participating in the Spanish breast cancer screening program from 2000–2006 and followed-up until 2009. A total of 5,309 screen-detected and 1,653 interval cancers were diagnosed. Among the latter, 1,012 could be classified on the basis of findings in screening and diagnostic mammograms, consisting of 489 true interval cancers (48.2%), 235 false-negatives (23.2%), 172 minimal-signs (17.2%) and 114 occult tumors (11.3%). Information on the screening protocol and women's characteristics were obtained from the screening program registry. Cause-specific Cox regression models were used to estimate the hazard ratios (HR) of risks factors for interval cancer and incident screen-detected cancer. A multinomial regression model, using screen-detected tumors as a reference group, was used to assess the effect of breast density and other factors on the occurrence of interval cancer subtypes. Results A previous false-positive was the main risk factor for interval cancer (HR = 2.71, 95%CI: 2.28–3.23); this risk was higher for false-negatives (HR = 8.79, 95%CI: 6.24–12.40) than for true interval cancer (HR = 2.26, 95%CI: 1.59–3.21). A family history of breast cancer was associated with true intervals (HR = 2.11, 95%CI: 1.60–2.78), previous benign biopsy with a false-negatives (HR = 1.83, 95%CI: 1.23–2.71). High breast density was mainly associated with occult tumors (RRR = 4.92, 95%CI: 2.58–9.38), followed by true intervals (RRR = 1.67, 95%CI: 1.18–2.36) and false-negatives (RRR = 1.58, 95%CI: 1.00–2.49).

Purpose. To describe integration of fundus autofluorescence (FAF) imaging into an ocular screening program. Methods. Fifty consecutive screening participants were included in this prospective pilot imaging study. Color and FAF (530/640 nm exciter/barrier filters) images were obtained with a 15.1MP Canon nonmydriatic hybrid camera. A clinician evaluated the images on site to determine need for referral. Visual acuity (VA), intraocular pressure (IOP), and ocular pathology detected by color fundus and FAF imaging modalities were recorded. Results. Mean ± SD age was 47.4 ± 17.3 years. Fifty-two percent were female and 58% African American. Twenty-seven percent had a comprehensive ocular examination within the past year. Mean VA was 20/39 in the right eye and 20/40 in the left eye. Mean IOP was 15 mmHg bilaterally. Positive color and/or FAF findings were identified in nine (18%) individuals with diabetic retinopathy or macular edema (n = 4), focal RPE defects (n = 2), age-related macular degeneration (n = 1), central serous retinopathy (n = 1), and ocular trauma (n = 1). Conclusions. FAF was successfully integrated in our ocular screening program and aided in the identification of ocular pathology. Larger studies examining the utility of this technology in screening programs may be warranted.

Employee wellness programs (EWPs) have been used to implement worksite-based cancer prevention and control interventions. However, little is known about whether these programs result in improved adherence to cancer screening guidelines or how participants' characteristics affect subsequent screening. This study was conducted to describe cancer screening behaviors among participants in a state EWP and identify factors associated with screening adherence among those who were initially nonadherent. We identified employees and their dependents who completed health risk assessments (HRAs) as part of the Kansas state EWP in both 2008 and 2009. We examined baseline rates of adherence to cancer screening guidelines in 2008 and factors associated with adherence in 2009 among participants who were initially nonadherent. Of 53,095 eligible participants, 13,222 (25%) participated in the EWP in 2008 and 6,205 (12%) participated in both years. Among the multiyear participants, adherence was high at baseline to screening for breast (92.5%), cervical (91.8%), and colorectal cancer (72.7%). Of participants who were initially nonadherent in 2008, 52.4%, 41.3%, and 33.5%, respectively, became adherent in the following year to breast, cervical, and colorectal cancer screening. Suburban/urban residence and more frequent doctor visits predicted adherence to breast and colorectal cancer screening guidelines. The effectiveness of EWPs for increasing cancer screening is limited by low HRA participation rates, high rates of adherence to screening at baseline, and failure of nonadherent participants to get screening. Improving overall adherence to cancer screening guidelines among employees will require efforts to increase HRA participation, stronger interventions for nonadherent participants, and better access to screening for rural employees.

Recent studies report racial disparities among individuals in organized colorectal cancer (CRC) programs; however, there is a paucity of information on CRC screening utilization by race/ethnicity among newly age-eligible adults in such programs. This was a retrospective cohort study among Kaiser Permanente Northern California enrollees who turned age 50 years between 2007 and 2012 (N=138,799) and were served by a systemwide outreach and facilitated in-reach screening program based primarily on mailed fecal immunochemical tests to screening-eligible people. Kaplan-Meier and Cox model analyses were used to estimate differences in receipt of CRC screening in 2015-2016. Cumulative probabilities of CRC screening within 1 and 2 years of subjects' 50th birthday were 51% and 73%, respectively. Relative to non-Hispanic whites, the likelihood of completing any CRC screening was similar in blacks (hazard ratio, 0.98; 95% CI=0.96, 1.00); 5% lower in Hispanics (hazard ratio, 0.95; 95% CI=0.93, 0.96); and 13% higher in Asians (hazard ratio, 1.13; 95% CI=1.11, 1.15) in adjusted analyses. Fecal immunochemical testing was the most common screening modality, representing 86% of all screening initiations. Blacks and Hispanics had lower receipt of fecal immunochemical testing in adjusted analyses. CRC screening uptake was high among newly screening-eligible adults in an organized CRC screening program, but Hispanics were less likely to initiate screening near age 50 years than non-Hispanic whites, suggesting that cultural and other individual-level barriers not addressed within the program likely contribute. Future studies examining the influences of culturally appropriate and targeted efforts for screening initiation are needed. Copyright © 2017 American Journal of Preventive Medicine.

Routine screening for breast and cervical cancers lowers mortality from these diseases, but the benefit has not permeated to Native American women, for whom the five-year survival rate is the lowest of any population group in the United States. To help address this problem, an educational/training program was designed to enhance the skills of nurses and other health service providers and develop clinic support systems to better recruit, screen, and follow clients for breast and cervical cancer screening services. A total of 131 nurses participated in the training program at 33 different sites between 1995 and 2000. Prior to and following training, each participant was given a questionnaire to determine knowledge of breast and cervical cancer screening techniques and recommendations, cancer survival and risk factors, and situational scenarios. The average score for the pretest was 54% correct. The posttest average was 89% correct. The percent correct increased 35% from pre- to posttest (p < 0.001). The knowledge to implement a successful screening program can be acquired through the current curriculum.

To develop, pilot and determine the feasibility of a sleep-specific screening and awareness program in community pharmacies. The screening was piloted in five Australian community pharmacies. The Pharmacy Tool for Assessment of Sleep Health was constructed by drawing on known relationships between sleep disorders, and lifestyle factors, medical conditions and medications. Four validated instruments were used in the screening tool: the Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), Multivariable Apnea Prediction Index (MAPI) and International Restless Legs Syndrome Study Group Screening Criteria (IRLS). These instruments were used to predict the participant's risk of a sleep disorder and the results were compared with reported lifestyle, medical and medication factors. On-site training of consenting pharmacists was provided, followed by an eight week client recruiting and screening period. Feedback was elicited from participating pharmacists and clients. The feasibility of, and trends found from, the developed screening tool and protocol. Of 167 clients who requested or were invited to participate by pharmacists, 84 (50.3%) were screened. Analysis of collected data indicated that 33.3%, 21.4% and 27.4% of participants were at risk of having or developing insomnia, obstructive sleep apnea (OSA) and restless legs syndrome (RLS) respectively, while 38.1% were not at risk of any of the screened disorders. OSA odds increased 12.8 times (95% CI: 3.2-50.4) with diabetes and 4.9 times (1.2-20.9) with opioid use, while shift workers were 8.4 times (1.6-43.2) more likely to have insomnia. Participants and pharmacists reported the screening protocol and instrument was user friendly and feasible. The development and pilot of this screening tool was successful. The prevalence of sleep disorders in the sampled population was high but generally consistent with previous studies on the general population. Furthermore, associations found may form a foundation for a

Neonatal hearing screening (NHS) has been routinely offered as a vital component of early childhood care in developed countries, whereas such a screening program is still at the pilot or preliminary stage as regards its nationwide implementation in developing countries. To provide significant evidence for health policy making in China, this study aims to determine the cost-effectiveness of NHS program implementation in case of eight provinces of China. A cost-effectiveness model was conducted and all neonates annually born from 2007 to 2009 in eight provinces of China were simulated in this model. The model parameters were estimated from the established databases in the general hospitals or maternal and child health hospitals of these eight provinces, supplemented from the published literature. The model estimated changes in program implementation costs, disability-adjusted life years (DALYs), average cost-effectiveness ratio (ACER), and incremental cost-effectiveness ratio (ICER) for universal screening compared to targeted screening in eight provinces. A multivariate sensitivity analysis was performed to determine uncertainty in health effect estimates and cost-effectiveness ratios using a probabilistic modeling technique. Targeted strategy trended to be cost-effective in Guangxi, Jiangxi, Henan, Guangdong, Zhejiang, Hebei, Shandong, and Beijing from the level of 9%, 9%, 8%, 4%, 3%, 7%, 5%, and 2%, respectively; while universal strategy trended to be cost-effective in those provinces from the level of 70%, 70%, 48%, 10%, 8%, 28%, 15%, 4%, respectively. This study showed although there was a huge disparity in the implementation of the NHS program in the surveyed provinces, both universal strategy and targeted strategy showed cost-effectiveness in those relatively developed provinces, while neither of the screening strategy showed cost-effectiveness in those relatively developing provinces. This study also showed that both strategies especially universal strategy

Background: A population-based program promoting the Fecal Occult Blood Test (FOBT) for colorectal cancer screening was introduced in 2008 in Ontario, Canada, where opportunistic screening with colonoscopy had been increasing in frequency. We evaluated the impact of the program on income and immigration-related disparities in screening. Methods: We used linked administrative data to calculate colorectal cancer screening rates for eligible Ontarians in each year between 2001/02 ( n = 2,852,619) and 2013/14 ( n = 4,139,304). We quantified disparities using an "inequality ratio" of screening rates in the most disadvantaged group relative to the most advantaged group. We performed segmented logistic regression analyses stratified by screening modality and adjusted for age, sex, rurality, comorbidity, and morbidity. Results: Between 2001/02 and 2013/14, the income and immigration inequality ratios narrowed from 0.74 to 0.80 and 0.55 to 0.69, respectively. Before the screening program, the income inequality ratio was widening by 1% per year (95% CI 1% to 1%); in the year it was introduced, it narrowed by 4% (95% CI 2% to 7%) and in the years following, it remained stable [0% decrease (95% CI 1% decrease to 0% decrease) per year]. Results were similar for immigration-related disparities. After program introduction, disparities in receiving FOBT were narrowing at a faster rate while disparities in receiving colonoscopy were widening at a slower rate. Conclusions: Introduction of a population-based screening program promoting FOBT for colorectal cancer was associated with only modest improvements in immigration and income-related disparities. Impact: Reducing immigration and income-related disparities should be a focus for future research and policy work. Disparities in Ontario seem to be driven by a higher uptake of colonoscopy among more advantaged groups.

Improvements in genetic testing technologies have led to the development of expanded carrier screening panels for the Ashkenazi Jewish population; however, there are major inconsistencies in current screening practices. A 2-year pilot program was launched in Atlanta in 2010 to promote and facilitate screening for 19 Jewish genetic diseases. We analyzed data from this program, including participant demographics and outreach efforts. This retrospective analysis is based on a de-identified dataset of 724 screenees. Data were obtained through medical chart review and questionnaires and included demographic information, screening results, response to outreach efforts, and follow-up behavior and preferences. We applied descriptive analysis, chi-square tests, and logistic regression to analyze the data and compare findings with published literature. The majority of participants indicated that they were not pregnant or did not have a partner who was pregnant were affiliated with Jewish organizations and reported 100 % AJ ancestry. Overall, carrier frequency was 1 in 3.9. Friends, rabbis, and family members were the most common influencers of the decision to receive screening. People who were older, had a history of pregnancy, and had been previously screened were more likely to educate others (all p < 0.05). Analysis of this 2-year program indicated that people who are ready to have children or expand their families are more likely to get screened and encourage others to be screened. The most effective outreach efforts targeted influencers who then encouraged screening in the target population. Educating influencers and increasing overall awareness were the most effective outreach strategies.

Preventive service delivery, including cancer screenings, continues to pose a challenge to quality improvement efforts. Although many studies have focused on person-level characteristics associated with screening, less is known about organizational influences on cancer screening. This study aims to understand the association between organizational factors and adherence to cancer screenings. This study employed a cross-sectional design using organizational-level, patient-level, and area-level data. Dependent variables included breast, cervical, and colorectal cancer screening. Organizational factors describing resource sufficiency were constructed using factor analyses from a survey of 250 Veterans Affairs primary care directors. We conducted random-effects logistic regression analyses, modeling cancer screening as a function of organizational factors, controlling for patient-level and area-level factors. Overall, 87% of the patients received mammograms, 92% received cervical and 78% had colorectal screening. Quality improvement orientation increased the odds of cervical [odds ratio (OR): 1.27; 95% confidence interval (CI), 1.03-1.57] and colorectal cancer screening (OR: 1.10; 95% CI, 1.00-1.20). Authority in determining primary care components increased the odds of mammography screening (OR: 1.23; 95% CI, 1.03-1.51). Sufficiency in clinical staffing increased the odds of mammography and cervical cancer screenings. Several patient-level factors, serving as control variables, were associated with achievement of screenings. Resource sufficiency led to increased odds of screening possibly because they promote excellence in patient care by conveying organizational goals and facilitate goal achievement with resources. Complementary to patient-level factors, our findings identified organizational processes associated with better performance, which offer concrete strategies in which facilities can evaluate their capabilities to implement best practices to foster and

Although guidelines recommend that clinicians consider life expectancy before screening older women for breast cancer, many older women with limited life expectancies are screened. We aimed to identify factors important to mammography screening decisions among women aged 80 and older compared to women aged 65-79. Telephone surveys of 107 women aged 80+ and 93 women aged 65-79 randomly selected from one academic primary care practice who were able to communicate in English (60% response rate). The survey addressed the following factors in regards to older women's mammography screening decisions: perceived importance of a history of breast disease, family history of breast cancer, doctor's recommendations, habit, reassurance, previous experience, mailed reminder cards, family/friend's recommendations or experience with breast cancer, age, health, and media. The survey also assessed older women's preferred role in decision making around mammography screening. Of the 200 women, 65.5% were non-Hispanic white and 82.8% were in good to excellent health. Most (81.3%) had undergone mammography in the past 2 years. Regardless of age, older women ranked doctor's recommendations as the most important factor influencing their decision to get screened. Habit and reassurance were the next two highly ranked factors influencing older women to get screened. Among women who did not get screened, women aged 80 and older ranked age and doctor's counseling as the most influential factors and women aged 65-79 ranked a previous negative experience with mammography as the most important factor. There were no significant differences in preferred role in decision-making around mammography screening by age, however, most women in both age groups preferred to make the final decision on their own (46.6% of women aged 80+ and 50.5% of women aged 65-79). While a doctor's recommendation is the most important factor influencing elderly women's mammography screening decisions, habit and reassurance

In the United States, Lung Cancer is responsible for more cancer deaths than the next four cancers combined. In addition, the 5 year survival rate for lung cancer patients has not improved over the past 40 to 50 years. To combat this deadly disease, in 2002 the National Cancer Institute launched a very large Randomized Control Trial called the National Lung Screening Trial (NLST). This trial would randomize subjects who had substantial risk of lung cancer (due to age and smoking history) into either a Chest X-ray arm or a low dose CT arm. In November 2010, the National Cancermore » Institute announced that the NLST had demonstrated 20% fewer lung cancer deaths among those who were screened with low-dose CT than with chest X-ray. In December 2013, the US Preventive Services Task Force recommended the use of Lung Cancer Screening using low dose CT and a little over a year later (Feb. 2015), CMS announced that Medicare would also cover Lung Cancer Screening using low dose CT. Thus private and public insurers are required to provide Lung Cancer Screening programs using CT to the appropriate population(s). The purpose of this Symposium is to inform medical physicists and prepare them to support the implementation of Lung Screening programs. This Symposium will focus on the clinical aspects of lung cancer screening, requirements of a screening registry for systematically capturing and tracking screening patients and results (such as required Medicare data elements) as well as the role of the medical physicist in screening programs, including the development of low dose CT screening protocols. Learning Objectives: To understand the clinical basis and clinical components of a lung cancer screening program, including eligibility criteria and other requirements. To understand the data collection requirements, workflow, and informatics infrastructure needed to support the tracking and reporting components of a screening program. To understand the role of the medical

Cellular antiviral programs can efficiently inhibit viral infection. These programs are often initiated through signaling cascades induced by secreted proteins such as type I interferons, IL-6 or TNF-α. Here, we generated an arrayed library of 756 human secreted proteins to perform a secretome screen focused on the discovery of novel modulators of viral entry and/or replication. The individual secreted proteins were tested for their capacity to inhibit infection by two replication-competent recombinant vesicular stomatitis viruses (VSV) with distinct glycoproteins utilizing different entry pathways. Fibroblast growth factor 16 (FGF16) was identified and confirmed as the most prominent novel inhibitor of both VSVs and therefore of viral replication and not entry. Importantly, an antiviral interferon signature was completely absent in FGF16 treated cells. Nevertheless, the antiviral effect of FGF16 is broad as it was evident on multiple cell types and also on infection of Coxsackievirus. In addition, other members of the FGF family also inhibited viral infection. Thus, our unbiased secretome screen revealed a novel protein family capable of inducing a cellular antiviral state. This previously unappreciated role of the FGF family may have implications for the development of new antivirals and the efficacy of oncolytic virus therapy. Importance Viruses infect human cells in order to replicate, while human cells aim to resist infection. Several cellular antiviral programs have therefore evolved to resist infection. Knowledge of these programs is essential for the design of antiviral therapeutics in the future. The induction of antiviral programs is often initiated by secreted proteins such as interferons. We hypothesized that other secreted proteins may also promote resistance to viral infection. Thus we tested 756 human secreted proteins for their capacity to inhibit two pseudotypes of vesicular stomatitis virus (VSV). In this first secretome screen on viral infection

Whole-Genome Screening of Newborns? The Constitutional Boundaries of State Newborn Screening Programs

State newborn screening (NBS) programs routinely screen nearly all of the 4 million newborns in the United States each year for ~30 primary conditions and a number of secondary conditions. NBS could be on the cusp of an unprecedented expansion as a result of advances in whole-genome sequencing (WGS). As WGS becomes cheaper and easier and as our knowledge and understanding of human genetics expand, the question of whether WGS has a role to play in state NBS programs becomes increasingly relevant and complex. As geneticists and state public health officials begin to contemplate the technical and procedural details of whether WGS could benefit existing NBS programs, this is an opportune time to revisit the legal framework of state NBS programs. In this article, we examine the constitutional underpinnings of state-mandated NBS and explore the range of current state statutes and regulations that govern the programs. We consider the legal refinements that will be needed to keep state NBS programs within constitutional bounds, focusing on 2 areas of concern: consent procedures and the criteria used to select new conditions for NBS panels. We conclude by providing options for states to consider when contemplating the use of WGS for NBS. PMID:26729704

Osteoporosis affects approximately 26% of women and 4% of men after the age of 65 years. However, the diffusion of knowledge about osteoporosis risk factors, prevention and treatment remains low. The purpose of this longitudinal study was to investigate the value of adding initial and refresher osteoporosis education classes to a bone health screening program. A convenience sample of 376 men (n = 62) and women (n = 314) over the age of 62 years was assigned randomly to the Screening plus Education (n =193) or Screening only (n = 183) groups. Participants in both study groups demonstrated an increase in knowledge about osteoporosis, regardless of group assignment and other factors, over the two years of the study. Self-reported calcium use increased for all women and for men in the education group from baseline to year one, with a decline thereafter. There was no effect on exercise behaviors. This study points out the critical need for a more comprehensive and personalized bone health program that includes more than classroom-based education. Copyright © 2010 Mosby, Inc.

The purpose of this study was to determine the national training practices of speech-language pathology graduate programs in outer and middle ear screening. Directors of all American Speech-Language-Hearing Association-accredited speech-language pathology graduate programs (N = 254; Council on Academic Accreditation in Audiology and Speech-Language Pathology, 2013) were surveyed on instructional formats in outer and middle ear screening. The graduate speech-language pathology program survey yielded 84 (33.1%) responses. Results indicated that some programs do not provide any training in the areas of conventional screening otoscopy using a handheld otoscope (15.5%; n = 13) or screening tympanometry (11.9%; n = 10), whereas close to one half (46.4%; n = 39) reported no training in screening video otoscopy. Outcomes revealed that approximately one third or more of speech-language pathology graduate programs do not provide experiential opportunities in screening handheld otoscopy (36.9%) or tympanometry (32.1%), and most (78.6%) do not provide experiential opportunities in video otoscopy. The implication from the graduate speech-language pathology program survey findings is that some speech-language pathologists will graduate from academic programs without the acquired knowledge or experiential learning required to establish skill in 1 or more areas of screening otoscopy and tympanometry. Graduate speech-language pathology programs should consider appropriate training opportunities for students to acquire and demonstrate skill in outer and middle ear screening.

Fall prevention is an important way to prevent fractures in person with osteoporosis. We developed and implemented a fall screening program in the context of routine osteoporosis care. This program was found to be feasible and showed that a significant proportion of persons with osteoporosis are at risk of falling. Falls are the most common cause of fracture in persons with osteoporosis. However, osteoporosis care rarely includes assessment and prevention of falling. We thus sought to assess the feasibility of a fall screening and management program integrated into routine osteoporosis care. The program was developed and offered to patients with osteoporosis or osteopenia seen at an outpatient clinic between May 2015 and May 2016. Feasibility was measured by physical therapist time required to conduct screening and ease of integrating the screening program into the usual clinic workflow. Self-report responses and mobility testing were conducted to describe the fall and fracture risk profile of osteoporosis patients screened. Effects on fall-related care processes were assessed via chart abstraction of patient participation in fall prevention exercise. Of the 154 clinic patients who presented for a clinic visit, 68% met screening criteria and completed in two thirds of persons. Screening was completed in a third of the time typically allotted for traditional PT evaluations and did not interfere with clinic workflow. Forty percent of those screened reported falling in the last year, and over half had two or more falls in the past year. Over half reported a balance or lower extremity impairment, and over 40% were below norms on one or more performance tests. Most patients who selected a group exercise fall prevention program completed all sessions while only a quarter completed either supervised or independent home-based programs. Implementation of a fall risk screening program in an outpatient osteoporosis clinic appears feasible. A substantial proportion of people

Existing research on barriers to breast and cervical cancer screening uptake has focused primarily on socio-demographic characteristics of individuals. However, contextual factors, such as service organization, as well as healthcare providers' training and practices, are more feasibly altered to increase health service use. The objective of the authors in this study was to perform a critical systematic review of the literature to identify contextual factors at the provider- and system-level that were associated with breast and cervical cancer screening uptake. Studies published from 2000 to 2013 were identified through PubMed and PsycInfo. Methodologic quality was assessed, and studies were examined for themes related to provider- and system-level factors associated with screening uptake. Thirteen studies met the inclusion criteria. Findings revealed a positive association between patients' receipt of provider recommendation and uptake of breast and cervical cancer screening. Uptake was also higher among patients of female providers. Facilities with flexible appointment times and reminders had higher mammography and Pap test uptake. Similarly, greater organizational commitment to quality and performance had higher breast and cervical cancer screening rates. Knowledge provided in this review could be used in future research to inform the development of public health policy and clinical programs to improve screening uptake.

Cost-effectiveness analysis of risk-factor guided and birth-cohort screening for chronic hepatitis C infection in the United States.

2013-01-01

No consensus exists on screening to detect the estimated 2 million Americans unaware of their chronic hepatitis C infections. Advisory groups differ, recommending birth-cohort screening for baby boomers, screening only high-risk individuals, or no screening. We assessed one-time risk assessment and screening to identify previously undiagnosed 40-74 year-olds given newly available hepatitis C treatments. A Markov model evaluated alternative risk-factor guided and birth-cohort screening and treatment strategies. Risk factors included drug use history, blood transfusion before 1992, and multiple sexual partners. Analyses of the National Health and Nutrition Examination Survey provided sex-, race-, age-, and risk-factor-specific hepatitis C prevalence and mortality rates. Nine strategies combined screening (no screening, risk-factor guided screening, or birth-cohort screening) and treatment (standard therapy-peginterferon alfa and ribavirin, Interleukin-28B-guided (IL28B) triple-therapy-standard therapy plus a protease inhibitor, or universal triple therapy). Response-guided treatment depended on HCV genotype. Outcomes include discounted lifetime costs (2010 dollars) and quality adjusted life-years (QALYs). Compared to no screening, risk-factor guided and birth-cohort screening for 50 year-olds gained 0.7 to 3.5 quality adjusted life-days and cost $168 to $568 per person. Birth-cohort screening provided more benefit per dollar than risk-factor guided screening and cost $65,749 per QALY if followed by universal triple therapy compared to screening followed by IL28B-guided triple therapy. If only 10% of screen-detected, eligible patients initiate treatment at each opportunity, birth-cohort screening with universal triple therapy costs $241,100 per QALY. Assuming treatment with triple therapy, screening all individuals aged 40-64 years costs less than $100,000 per QALY. The cost-effectiveness of one-time birth-cohort hepatitis C screening for 40-64 year olds is comparable

BACKGROUND Colorectal cancer, as the second leading cause of cancer-related deaths among men and women in the United States, represents an important area for public health intervention. Although colorectal cancer screening can prevent cancer and detect disease early when treatment is most effective, few organized public health screening programs have been implemented and evaluated. From 2005 to 2009, the Centers for Disease Control and Prevention funded 5 sites to participate in the Colorectal Cancer Screening Demonstration Program (CRCSDP), which was designed to reach medically underserved populations. METHODS The authors conducted a longitudinal, multiple case study to analyze program implementation processes. Qualitative methods included interviews with 100 stakeholders, 125 observations, and review of 19 documents. Data were analyzed within and across cases. RESULTS Several themes related to CRCSDP implementation emerged from the cross-case analysis: the complexity of colorectal cancer screening, the need for teamwork and collaboration, integration of the program into existing systems, the ability of programs to use wisdom at the local level, and the influence of social norms. Although these themes were explored independently from 1 another, interaction across themes was evident. CONCLUSIONS Colorectal cancer screening is clinically complex, and its screening methods are not well accepted by the general public; both of these circumstances have implications for program implementation. Using patient navigation, engaging in transdisciplinary teamwork, assimilating new programs into existing clinical settings, and deferring to local-level wisdom together helped to address complexity and enhance program implementation. In addition, public health efforts must confront negative social norms around colorectal cancer screening. PMID:23868482

To evaluate the impact of an intervention in primary care professionals on their current knowledge about colorectal cancer screening, subsequent surveillance recommendations and referral strategies. Cluster randomized controlled trial. Primary Care Centers in L'Hospitalet de Llobregat (Barcelona). Primary Care Professionals (doctors and nurses). Training session in six of the 12 centers (randomly selected) about the colorrectal cancer screening program, and three emails with key messages. Professionals and centers characteristics and two contextual variables; involvement of professionals in the screening program; information about colorectal cancer knowledge, risk factors, screening procedures, surveillance recommendations and referral strategies. The total score mean on the first questionnaire was 8.07 (1.38) and the second 8.31 (1.39). No statistically significant differences between the intervention and control groups were found, however, in 9 out of 11 questions the percentage of correct responses was increased in the intervention group, mostly related to the surveillance after the diagnostic examination. The intervention improves the percentage of correct answers, especially in those in which worst score obtained in the first questionnaire. This study shows that professionals are familiar with colorectal cancer screening, but there's a need to maintain frequent communication in order to keep up to date the information related to the colorectal cancer screening.

Congenital hypothyroidism and phenylketonuria (PKU) are the most common cause for preventable mental retardation in infants worldwide. Timely diagnosis and treatment of these disorders can have lasting effects on the mental development of newborns. However, there are several problems at different stages of screening programs that along with imposing heavy costs can reduce the precision of the screening, increasing the chance of undiagnosed cases which in turn can have damaging consequences for the society. Therefore, given these problems and the importance of information systems in facilitating the management and improving the quality of health care the aim of this study was to improve the screening process of hypothyroidism and PKU in infants with the help of electronic resources. The current study is a qualitative, action research designed to improve the quality of screening, services, performance, implementation effectiveness, and management of hypothyroidism and PKU screening program in Isfahan province. To this end, web-based software was designed. Programming was carried out using Delphi.net software and used SQL Server 2008 for database management. Given the weaknesses, problems, and limitations of hypothyroidism and PKU screening program, and the importance of these diseases in a national scale, this study resulted in design of hypothyroidism and PKU screening software for infants in Isfahan province. The inputs and outputs of the software were designed in three levels including Health Care Centers in charge of the screening program, provincial reference lab, and health and treatment network of Isfahan province. Immediate registration of sample data at the time and location of sampling, providing the provincial reference Laboratory and Health Centers of different eparchies with the ability to instantly observe, monitor, and follow-up on the samples at any moment, online verification of samples by reference lab, creating a daily schedule for reference lab

To investigate the probability of breast cancer among women recalled due to abnormal findings on the screening mammograms (PPV-1) and among women who underwent an invasive procedure (PPV-2) by mammographic density (MD), screening mode and age. We used information about 28,826 recall examinations from 26,951 subsequently screened women in the Norwegian Breast Cancer Screening Program, 1996-2010. The radiologists who performed the recall examinations subjectively classified MD on the mammograms into three categories: fatty (<30% fibroglandular tissue); medium dense (30-70%) and dense (>70%). Screening mode was defined as screen-film mammography (SFM) and full-field digital mammography (FFDM). We examined trends of PPVs by MD, screening mode and age. We used logistic regression to estimate odds ratio (OR) of screen-detected breast cancer associated with MD among women recalled, adjusting for screening mode and age. PPV-1 and PPV-2 decreased by increasing MD, regardless of screening mode (p for trend <0.05 for both PPVs). PPV-1 and PPV-2 were statistically significantly higher for FFDM compared with SFM for women with fatty breasts. Among women recalled, the adjusted OR of breast cancer decreased with increasing MD. Compared with women with fatty breasts, the OR was 0.90 (95% CI: 0.84-0.96) for those with medium dense breasts and 0.85 (95% CI: 0.76-0.95) for those with dense breasts. PPVs decreased by increasing MD. Fewer women needed to be recalled or undergo an invasive procedure to detect one breast cancer among those with fatty versus dense breasts in the screening program in Norway, 1996-2010.

Although measuring parent satisfaction has been recommended as one of the important outcome measures in assessing the effectiveness of neonatal hearing screening programs, there are few published studies investigating this issue. To validate the Spanish version of the Parent Satisfaction Questionnaire with Neonatal Hearing Screening Program (PSQ-NHSP). 112 parents whose children had received hearing screening participated in this study. High levels of satisfaction were reported with more than 90% of parents satisfied with all aspects of the program. The psychometric properties of the Spanish version of the PSQ-NHSP were analyzed and demonstrated good internal consistency (alpha=0.75). Construct validity was indicated by a significant positive relationship between overall satisfaction and the three specific dimensions in the questionnaire. The development of a valid and reliable parent satisfaction questionnaire is important for improving hearing screening programs.

Multiple advisory groups now recommend that high-risk smokers be screened for lung cancer by low-dose computed tomography. Given that the development of lung cancer screening programs will face many of the same issues that have challenged other cancer screening programs, the National Cancer Institute-funded Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium was used to identify lessons learned from the implementation of breast, cervical, and colorectal cancer screening that should inform the introduction of lung cancer screening. These lessons include the importance of developing systems for identifying and recruiting eligible individuals in primary care, ensuring that screening centers are qualified and performance is monitored, creating clear communication standards for reporting screening results to referring physicians and patients, ensuring follow-up is available for individuals with abnormal test results, avoiding overscreening, remembering primary prevention, and leveraging advances in cancer genetics and immunology. Overall, this experience emphasizes that effective cancer screening is a multistep activity that requires robust strategies to initiate, report, follow up, and track each step as well as a dynamic and ongoing oversight process to revise current screening practices as new evidence regarding screening is created, new screening technologies are developed, new biological markers are identified, and new approaches to health care delivery are disseminated.

Dockres: a computer program that analyzes the output of virtual screening of small molecules

PubMed Central

2010-01-01

Background This paper describes a computer program named Dockres that is designed to analyze and summarize results of virtual screening of small molecules. The program is supplemented with utilities that support the screening process. Foremost among these utilities are scripts that run the virtual screening of a chemical library on a large number of processors in parallel. Methods Dockres and some of its supporting utilities are written Fortran-77; other utilities are written as C-shell scripts. They support the parallel execution of the screening. The current implementation of the program handles virtual screening with Autodock-3 and Autodock-4, but can be extended to work with the output of other programs. Results Analysis of virtual screening by Dockres led to both active and selective lead compounds. Conclusions Analysis of virtual screening was facilitated and enhanced by Dockres in both the authors' laboratories as well as laboratories elsewhere. PMID:20205801

The functional movement screen is developed to examine individuals' movement patterns through 7 functional tasks. The purpose of this study was to identify the internal consistency and factor structure of the 7 tasks of the functional movement screen in elite athletes; 290 elite athletes from a variety of Chinese national teams were assessed using the functional movement screen. Cronbach's alpha was calculated for the scores of the 7 tasks. Exploratory factor analysis was performed to explore the factor structure of the functional movement screen. The mean and standard deviation of the sum score were 15.2 ± 3.0. A low Cronbach's alpha (0.58) was found for the scores of the 7 tasks. Exploratory factor analysis extracted 2 factors with eigenvalues greater than 1, and these 2 factors explained 47.3% of the total variance. The first factor had a high loading on the rotatory stability (loading = 0.99) and low loadings on the other 6 tasks (loading range: 0.04-0.34). The second factor had high loadings on the deep squat, hurdle step and inline lunge (loading range: 0.46-0.61) and low loadings on the other 3 tasks (loading range: 0.12-0.32). The 7 tasks of the functional movement screen had low internal consistency and were not indicators of a single factor. Evidence for unidimensionality was not found for the functional movement screen in elite athletes. More attention should be paid to the score of each task rather than the sum score when we interpret the functional movement screen scores.

Data integration and warehousing: coordination between newborn screening and related public health programs.

PubMed

Therrell, Bradford L

2003-01-01

At birth, patient demographic and health information begin to accumulate in varied databases. There are often multiple sources of the same or similar data. New public health programs are often created without considering data linkages. Recently, newborn hearing screening (NHS) programs and immunization programs have virtually ignored the existence of newborn dried blood spot (DBS) newborn screening databases containing similar demographic data, creating data duplication in their 'new' systems. Some progressive public health departments are developing data warehouses of basic, recurrent patient information, and linking these databases to other health program databases where programs and services can benefit from such linkages. Demographic data warehousing saves time (and money) by eliminating duplicative data entry and reducing the chances of data errors. While newborn screening data are usually the first data available, they should not be the only data source considered for early data linkage or for populating a data warehouse. Birth certificate information should also be considered along with other data sources for infants that may not have received newborn screening or who may have been born outside of the jurisdiction and not have birth certificate information locally available. This newborn screening serial number provides a convenient identification number for use in the DBS program and for linking with other systems. As a minimum, data linkages should exist between newborn dried blood spot screening, newborn hearing screening, immunizations, birth certificates and birth defect registries.

The aim of this paper is to share our experience and observations in running the Universal Neonatal Hearing Screening Program on a national level, present results and indicate some problems that have arisen during these 4 years. Polish Universal Neonatal Hearing Screening Program started back in 2002 in all neonatal units in Poland. Implemented testing methods consisted of test of transient evoked otoacoustic emission (TEOAE) performed in all new born children in their first 2-3 days of life and auditory brainstem response testing (ABR) conducted on children, who did not meet the TEOAE pass criteria. Additional questionnaire registered information on ototoxic drugs and family history of hearing impairment in every newborn. Diagnosed children were further referred for treatment and rehabilitation. After 4 years of running the program (between 2003 and 2006) a total number of 1,392,427 children were screened for hearing impairment, what stands for 96.3% of all delivered babies, registered in Poland. The screening program enabled to identify and refer for further treatment 2485 children with various types of hearing loss, 312 with profound (0.02% of population) and 145 with severe sensorineural hearing loss (0.11% of population). Our results indicate the accuracy of newborn hearing screening which remain an issue. Although improvement is needed in both intervention systems and diagnostic follow-up of hospitals, the Polish Universal Neonatal Hearing Program fully has achieved the main goal, the identification and treatment of hearing impaired children.

Lack of follow-up exams after failed school vision screenings: an investigation of contributing factors.

Programs to facilitate professional eye exams after failed school vision screenings often are based on the assumption that funding and access to services are major obstacles to care. Despite such programs, many children do not receive professional exams. The purpose of this study was to identify additional barriers to follow-up eye care. School nurses in an urban, midwestern public school district identified elementary school students who had not received follow-up eye exams after failed school vision screenings. Parents of these students were interviewed during the summer to determine financial, logistical, social/family, and perceptual barriers to care. Family issues, parental perceptions of vision problems, and difficulty planning ahead were found to be significant factors. Strategies to increase follow-up compliance and recommendations for overcoming barriers to care were also identified.

The Next Step Trial was a randomized trial of worksite colorectal cancer screening promotion and nutrition interventions for automobile industry employees at increased risk of colorectal cancer. Interventions were tested at 28 worksites with 5,042 employees. This report describes results of the screening promotion intervention. Worksites randomized to the control group received a standard program including rectal examination, fecal occult blood testing, and flexible sigmoidoscopy. Intervention worksites received an enhanced program (i.e., standard program plus an educational booklet/telephone call). Compliance (i.e., completion of all recommended screening examinations) and coverage (i.e., completion of at least one screening examination), the primary and secondary outcomes, were measured over 2 years. In the 2 years prior to baseline, 61% of employees had been screened. After random assignment, baseline differences in several employee characteristics and worksite screening procedures were detected, including more past history of screening in control worksites. After adjusting for differences, we found modest, but higher, compliance and coverage in intervention compared with control worksites (odds ratio [95% confidence limits] = 1.46 [1.1-2.0] and 1.33 [1.1, 1.6], respectively). Adding a personally tailored behavioral intervention to a standard colorectal cancer screening program can promote continued employee participation in screening as measured by compliance. Further research is needed to assess intervention effects in other populations. Copyright 1999 American Health Foundation and Academic Press.

The need for supplemental breast cancer screening modalities: a perspective of population-based breast cancer screening programs in Japan.

PubMed

Uematsu, Takayoshi

This article discusses possible supplemental breast cancer screening modalities for younger women with dense breasts from a perspective of population-based breast cancer screening program in Japan. Supplemental breast cancer screening modalities have been proposed to increase the sensitivity and detection rates of early stage breast cancer in women with dense breasts; however, there are no global guidelines that recommend the use of supplemental breast cancer screening modalities in such women. Also, no criterion standard exists for breast density assessment. Based on the current situation of breast imaging in Japan, the possible supplemental breast cancer screening modalities are ultrasonography, digital breast tomosynthesis, and breast magnetic resonance imaging. An appropriate population-based breast cancer screening program based on the balance between cost and benefit should be a high priority. Further research based on evidence-based medicine is encouraged. It is very important that the ethnicity, workforce, workflow, and resources for breast cancer screening in each country should be considered when considering supplemental breast cancer screening modalities for women with dense breasts.

Colorectal cancer screening is a life-saving intervention, but screening rates are low. The authors implemented and evaluated the Spokane Colorectal Cancer Screening Program-a novel worksite intervention to promote colorectal cancer screening that used a combination of evidence-based strategies recommended by the Guide to Community Preventive Services, as well as additional strategies. Over a period of approximately 3 months, participating worksites held one or more physician-led seminars about colorectal cancer screening for employees. They also distributed free fecal immunochemical tests at the worksite to employees 50 years and older, and they provided test results to employees and their primary care physician. The authors measured attendance at seminars, test kits taken and returned, employee awareness of the program, and colorectal cancer screening rates in participating and comparison worksites. It is estimated that 9% of eligible employees received kits at the worksite, and 4% were screened with these kits. The Spokane Colorectal Cancer Screening Program was a promising pilot test of an innovative worksite screening program that successfully translated evidence-based strategies into practical use in a brief period of time, and it merits a larger study to be able to test its effects more rigorously.

In most industrialized countries, screening programs for cervical cancer have shifted from cytology (Pap smear or ThinPrep) alone on clinician-obtained samples to the addition of screening for human papillomavirus (HPV), its main causative agent. For HPV testing, self-sampling instead of clinician-sampling has proven to be equally accurate, in particular for assays that use nucleic acid amplification techniques. In addition, HPV testing of self-collected samples in combination with a follow-up Pap smear in case of a positive result is more effective in detecting precancerous lesions than a Pap smear alone. Self-sampling for HPV testing has already been adopted by some countries, while others have started trials to evaluate its incorporation into national cervical cancer screening programs. Self-sampling may result in more individuals willing to participate in cervical cancer screening, because it removes many of the barriers that prevent women, especially those in low socioeconomic and minority populations, from participating in regular screening programs. Several studies have shown that the majority of women who have been underscreened but who tested HPV-positive in a self-obtained sample will visit a clinic for follow-up diagnosis and management. In addition, a self-collected sample can also be used for vaginal microbiome analysis, which can provide additional information about HPV infection persistence as well as vaginal health in general.

PURPOSE Bahçeşehir Breast Cancer Screening Program is a population based organized screening program in Turkey, where asymptomatic women aged 40–69 years are screened biannually. In this prospective study, we aimed to determine the mammographic findings of screen-detected cancers and discuss the efficacy of breast cancer screening in a developing country. METHODS A total of 6912 women were screened in three rounds. The radiologic findings were grouped as mass, focal asymmetry, calcification, and architectural distortion. Masses were classified according to shape, border, and density. Calcifications were grouped according to morphology and distribution. Cancers were grouped according to the clinical stage. RESULTS Seventy cancers were detected with an incidence of 4.8/1000. Two cancers were detected in other centers and three were not visualized mammographically. Mammographic presentations of the remaining 65 cancers were mass (47.7%, n=31), calcification (30.8%, n=20), focal asymmetry (16.9%, n=11), architectural distortion (3.1%, n=2), and skin thickening (1.5%, n=1). The numbers of stage 0, 1, 2, 3, and 4 cancers were 13 (20.0%), 34 (52.3%), 14 (21.5%), 3 (4.6%), and 1 (1.5%), respectively. The numbers of interval and missed cancers were 5 (7.4%) and 7 (10.3%), respectively. CONCLUSION A high incidence of early breast cancer has been detected. The incidence of missed and interval cancers did not show major differences from western screening trials. We believe that this study will pioneer implementation of efficient population-based mammographic screenings in developing countries. PMID:27705880

Breast cancer is the first cancer among females in the Kingdom of Saudi Arabia, accounting for 27.4% of all newly diagnosed female cancers in 2010. There are several risk factors affecting the incidence of breast cancer where some factors influence the risk more than the others. We aimed to identify the different risk factors related to breast cancer among females participating in the breast-screening program in Riyadh, KSA. Based on data from phase-I of the breast-screening program, a case-control study was conducted on women living in Riyadh, KSA. A sample of 349 women (58 cases and 290 controls) was recruited to examine the different breast cancer correlates. Multivariate regression model was built to investigate the most important risk factors. The mean age of cases was 48.5±7.1 years. Age at marriage, number of pregnancy, age at menopause, oral contraceptive pills, breast feeding and family history of breast cancer in first-degree relative were identified as the most important correlates among the studied cohort. The findings of the current work suggested that age at marriage, age at menopause ⩾50 years and 1st degree family history of breast cancer were risk factors for breast cancer, while, age at menopause <50 years, number of pregnancies and practicing breast feeding were protective factors against breast cancer. There was no effect of body mass index or physical inactivity. Further studies are needed to explore the hereditary, familial and genetic background risk factors in Saudi population.

Prostate cancer is rapidly increasing in Korea and professional societies have requested adding prostate specific antigen (PSA) testing to the National Cancer Screening Program (NCSP), but this started a controversy in Korea and neutral evidence on this issue is required more than ever. The purpose of this study was to provide economic evidence to the decision makers of the NCSP. A cost-utility analysis was performed on the adoption of PSA screening program among men aged 50-74-years in Korea from the healthcare system perspective. Several data sources were used for the cost-utility analysis, including general health screening data, the Korea Central Cancer Registry, national insurance claims data, and cause of mortality from the National Statistical Office. To solicit the utility index of prostate cancer, a face-to-face interview for typical men aged 40 to 69 was conducted using a Time-Trade Off method. As a result, the increase of effectiveness was estimated to be very low, when adopting PSA screening, and the incremental cost effectiveness ratio (ICER) was analyzed as about 94 million KRW. Sensitivity analyses were performed on the incidence rate, screening rate, cancer stage distribution, utility index, and treatment costs but the results were consistent with the base analysis. Under Korean circumstances with a relatively low incidence rate of prostate cancer, PSA screening is not cost-effective. Therefore, we conclude that adopting national prostate cancer screening would not be beneficial until further evidence is provided in the future.

Correction factors for self-selection when evaluating screening programmes.

In screening programmes there is recognized bias introduced through participant self-selection (the healthy screenee bias). Methods used to evaluate screening programmes include Intention-to-screen, per-protocol, and the "post hoc" approach in which, after introducing screening for everyone, the only evaluation option is participants versus non-participants. All methods are prone to bias through self-selection. We present an overview of approaches to correct for this bias. We considered four methods to quantify and correct for self-selection bias. Simple calculations revealed that these corrections are actually all identical, and can be converted into each other. Based on this, correction factors for further situations and measures were derived. The application of these correction factors requires a number of assumptions. Using as an example the German Neuroblastoma Screening Study, no relevant reduction in mortality or stage 4 incidence due to screening was observed. The largest bias (in favour of screening) was observed when comparing participants with non-participants. Correcting for bias is particularly necessary when using the post hoc evaluation approach, however, in this situation not all required data are available. External data or further assumptions may be required for estimation. © The Author(s) 2015.

Community-Based Multidisciplinary Computed Tomography Screening Program Improves Lung Cancer Survival.

2016-05-01

Lung cancer is the most common cause of cancer deaths in the United States. Overall survival is less than 20%, with the majority of patients presenting with advanced disease. The National Lung Screening Trial, performed mainly in academic medical centers, showed that cancer mortality can be reduced with computed tomography (CT) screening compared with chest radiography in high-risk patients. To determine whether this survival advantage can be duplicated in a community-based multidisciplinary thoracic oncology program, we initiated a CT scan screening program for lung cancer within an established health care system. In 2008, we launched a lung cancer CT screening program within the WellStar Health System (WHS) consisting of five hospitals, three health parks, 140 outpatient medical offices, and 12 imaging centers that provide care in a five-county area of approximately 1.4 million people in Metro-Atlanta. Screening criteria incorporated were the International Early Lung Cancer Action Program (2008 to 2010) and National Comprehensive Cancer Network guidelines (2011 to 2013) for moderate- and high-risk patients. A total of 1,267 persons underwent CT lung cancer screening in WHS from 2008 through 2013; 53% were men, 87% were 50 years of age or older, and 83% were current or former smokers. Noncalcified indeterminate pulmonary nodules were found in 518 patients (41%). Thirty-six patients (2.8%) underwent a diagnostic procedure for positive findings on their CT scan; 30 proved to have cancer, 28 (2.2%) primary lung cancer and 2 metastatic cancer, and 6 had benign disease. Fourteen patients (50%) had their lung cancer discovered on their initial CT scan, 11 on subsequent scans associated with indeterminate pulmonary nodules growth and 3 patients who had a new indeterminate pulmonary nodules. Only 15 (54%) of these 28 patients would have qualified as a National Lung Screening Trial high-risk patient; 75% had stage I or II disease. Overall 5-year survival was 64% and 5-year

The rates of participation in the Korean nationwide cervical cancer screening program and the rates of abnormal test results were determined. The database of the National Health Insurance Service (NHIS) was used during the study period (2009-2014). The participation rate increased from 41.10% in 2009 to 51.52% in 2014 (annual percentage change, 4.126%; 95% confidence interval [CI]=2.253-6.034). During the study period, women ≥70 years of age had the lowest rate of participation (range, 21.7%-31.9%) and those 30-39 years of age the second-lowest (27.7%-44.9%). The participation rates of National Health Insurance beneficiaries (range, 48.6%-52.5%) were higher than those of Medical Aid Program (MAP) recipients (29.6%-33.2%). The rates of abnormal results were 0.65% in 2009 and 0.52% in 2014, with a decreasing tendency in all age groups except the youngest (30-39 years). Every year the abnormal result rates tended to decrease with age, from the age groups of 30-39 years to 60-69 years but increased in women ≥70 years of age. The ratio of patients with atypical squamous cells of undetermined significance compared with those with squamous intraepithelial lesions increased from 2.71 in 2009 to 4.91 in 2014. Differences related to age and occurring over time were found in the rates of participation and abnormal results. Further efforts are needed to encourage participation in cervical cancer screening, especially for MAP recipients, elderly women and women 30-39 years of age. Quality control measures for cervical cancer screening programs should be enforced consistently. Copyright © 2017. Asian Society of Gynecologic Oncology, Korean Society of Gynecologic Oncology

Parent-Child Relationships: Implementation of a Screening and Referral Program for Adolescents With Mood Disorders.

2017-11-01

Parent-child relational problems (PCRP) have been increasingly recognized as a risk factor in the development and/or progression of childhood mental illnesses. Despite many young individuals being at risk, health care providers do not specifically screen for PCRP in children diagnosed with mental illnesses. The objective of the current project was to implement a PCRP screening program in a metropolitan children's hospital and refer those with PCRP for treatment. Adolescents ages 10 to 17 presenting for admission in an inpatient pediatric psychiatric unit were screened with the PCRP semi-structured questionnaire and diagnostic criteria developed by the American Psychiatric Association's Relational Processes Workgroup. Eleven (73%) of 15 patients screened were found to have PCRP. Patients may be screened with a PCRP screening tool during biopsychosocial assessment without undue time burden on the provider. It is recommended that PCRP be added to electronic health records so providers can select PCRP in problem lists as well as formulate PCRP-sensitive care plans.

Objectives To examine factors that enhance under-screened and never-screened women’s completion of the self-collection alternative pathway of the Renewed National Cervical Screening Program (ncsp) in Victoria, Australia. Background With the Australian ncsp changing, starting on 1 December 2017, the Medical Services Advisory Committee (msac) recommended implementing human papillomavirus (hpv) testing using a self-collected sample for under-screened and never-screened populations. In response, a multi-agency group implemented an hpv self-collection pilot project to trial self-collection screening pathways for eligible women. Methods Quantitative data were collected on participation rates and compliance rates with follow-up procedures across three primary health care settings. Forty women who self-collected were interviewed in a semi-structured format, and seven agency staff completed in-depth interviews. Qualitative data were used to identify and understand clinical and personal enablers that assisted women to complete self-collection cervical screening pathways successfully. Results Eighty-five per cent (10 women) of participants who tested positive for hpv successfully received their results and completed follow-up procedures as required. Two remaining participants also received hpv-positive results. However, agencies were unable to engage them in follow-up services and procedures. The overall participation rate in screening (self-collection or Pap test) was 85.7% (84 women), with 79 women self-collecting. Qualitative data indicated that clear explanations on self-collection, development of trusting, empathetic relationships with health professionals, and recognition of participants’ past experiences were critical to the successful completion of the self-collection pathway. When asked about possible inhibitors to screening and to following up on results and appointments, women cited poor physical and mental health, as well as financial and other structural

Forty women who self-collected were interviewed in a semi-structured format, and seven agency staff completed in-depth interviews. Qualitative data were used to identify and understand clinical and personal enablers that assisted women to complete self-collection cervical screening pathways successfully. Eighty-five per cent (10 women) of participants who tested positive for hpv successfully received their results and completed follow-up procedures as required. Two remaining participants also received hpv-positive results. However, agencies were unable to engage them in follow-up services and procedures. The overall participation rate in screening (self-collection or Pap test) was 85.7% (84 women), with 79 women self-collecting. Qualitative data indicated that clear explanations on self-collection, development of trusting, empathetic relationships with health professionals, and recognition of participants' past experiences were critical to the successful completion of the self-collection pathway. When asked about possible inhibitors to screening and to following up on results and appointments, women cited poor physical and mental health, as well as financial and other structural barriers. A well-implemented process, led by

Assess patient adherence to radiologist recommendations in a clinical CT lung cancer screening program. Patients undergoing CT lung cancer screening between January 12, 2012, and June 12, 2013, were included in this institutional review board-approved retrospective review. Patients referred from outside our institution were excluded. All patients met National Comprehensive Cancer Network Guidelines Lung Cancer Screening high-risk criteria. Full-time program navigators used a CT lung screening program management system to schedule patient appointments, generate patient result notification letters detailing the radiologist follow-up recommendation, and track patient and referring physician notification of missed appointments at 30, 60, and 90 days. To be considered adherent, patients could be no more than 90 days past due for their next recommended examination as of September 12, 2014. Patients who died, were diagnosed with cancer, or otherwise became ineligible for screening were considered adherent. Adherence rates were assessed across multiple variables. During the study interval, 1,162 high-risk patients were screened, and 261 of 1,162 (22.5%) outside referrals were excluded. Of the remaining 901 patients, 503 (55.8%) were male, 414 (45.9%) were active smokers, 377 (41.8%) were aged 65 to 73, and >95% were white. Of the 901 patients, 772 (85.7%) were adherent. Most common reasons for nonadherence were patient refusal of follow-up exam (66.7%), inability to successfully contact the patient (20.9%), and inability to obtain the follow-up order from the referring provider (7.8%); 23 of 901 (2.6%) were discharged for other reasons. High rates of adherence to radiologist recommendations are achievable for in-network patients enrolled in a clinical CT lung screening program. Copyright © 2017 American College of Radiology.

A Systematic Review of the Factors Influencing Ethnic Minority Women's Cervical Cancer Screening Behavior: From Intrapersonal to Policy Level.

PubMed

Chan, Dorothy N S; So, Winnie K W

Cervical cancer can be prevented by effective screening using Papanicolaou tests, but the utilization rate is lower among ethnic minorities than in the general population. Understanding the factors influencing minorities' use of such screening can aid the design of an appropriate intervention to increase their uptake rate. The aims of this study were to examine the factors that influence ethnic minority women in using cervical cancer screening and the similarities and differences in associated factors across different groups and to explore the interrelationships between the factors identified. A literature search was conducted using Ovid MEDLINE, Cumulative Index to Nursing and Allied Health Literature Plus, Scopus, PsycINFO, and PubMed. Furthermore, 1390 articles were retrieved, of which 24 met the inclusion criteria. Critical appraisal was performed by means of a quality assessment tool. The findings were summarized in tabular and narrative forms. The findings showed that certain factors commonly affected ethnic minority women's screening behavior, including knowledge, attitude and perceptions, physician's recommendation, quality of care and service, language, and acculturation. Culture-related factors, religion, and acculturation exhibited close interrelationships with the attitude and perceptions factor, resulting in behavioral change. The review sheds light on how common or unique are the factors across ethnic minorities and how these factors interact to influence behavior. Further studies are warranted to develop and test empirically a comprehensive model leading to a better understanding of the interrelationships between multiple factors. The model should be useful in informing policy makers about appropriate resource allocation and in guiding the development of culturally relevant programs to increase screening uptake.

BACKGROUND The Centers for Disease Control and Prevention initiated the Colorectal Cancer Screening Demonstration Program (CRCSDP) to explore the feasibility of establishing a large-scale colorectal cancer (CRC) screening program for underserved populations in the United States. The authors of this report assessed the clinical costs incurred at each of the 5 participating sites during the demonstration period. METHODS By using data on payments to providers by each of the 5 CRCSDP sites, the authors estimated costs for specific clinical services and overall clinical costs for each of the 2 CRC screening methods used by the sites: colonoscopy and fecal occult blood test (FOBT). RESULTS Among CRCSDP clients who were at average risk for CRC and for whom complete cost data were available, 2131 were screened by FOBT, and 1888 were screened by colonoscopy. The total average clinical cost per individual screened by FOBT (including costs for screening, diagnosis, initial surveillance, office visits, and associated clinical services averaged across all individuals who received screening FOBT) ranged from $48 in Nebraska to $149 in Greater Seattle. This compared with an average clinical cost per individual for all services related to the colonoscopy screening ranging from $654 in St. Louis to $1600 in Baltimore City. CONCLUSIONS Variations in how sites contracted with providers and in the services provided through CRCSDP affected the cost of clinical services and the complexity of collecting cost data. Health officials may find these data useful in program planning and budgeting. PMID:23868481

Colorectal cancer screening program using fecal immunochemical test had been conducted on an isolated island named Nii-jima. However, the participation rate of the program had been approximately 12%, which was lower than average level of Japan. This study aimed to evaluate the participation rate, safety and efficacy of a colorectal cancer screening program using colonoscopy on the island. Educational campaigns were actively conducted every month using information bulletins and special propaganda pamphlets. The primary recommended modality was colonoscopy, followed by fecal immunochemical test. The participants of this program were 1671 individuals aged 40–79 years (men, 819; women, 852). A total of 789 (47.2%) individuals provided consent for this screening program, and 89.2% (704/789) of participants chose colonoscopy as the primary screening procedure. The completion rate of total colonoscopy was 99.7%, and there was no complication during this program. Detection rates of invasive cancer, intramucosal cancer, advanced neoplasia and any adenoma were 0.9% (n = 6), 2.4% (n = 17), 11.8% (n = 83) and 50.0% (n = 352), respectively. The adenoma detection rate and incidence of advanced neoplasia were significantly higher in men than in women in all age groups. The colorectal cancer screening program using colonoscopy that was conducted on an island achieved considerably higher participation rate than the conventional screening program using fecal immunochemical test. Completion rate and safety of screening colonoscopy were excellent during this program.

Different screening strategies exist to estimate the risk of tubal factor subfertility, preceding laparoscopy. Three screening strategies, comprising Chlamydia trachomatis IgG antibody testing (CAT), high-sensitivity C-reactive protein (hs-CRP) testing and hysterosalpingography (HSG), were explored using laparoscopy as reference standard and the occurrence of a spontaneous pregnancy as a surrogate marker for the absence of tubal pathology. In this observational study, 642 subfertile women, who underwent tubal testing, participated. Data on serological testing, HSG, laparoscopy and interval conception were collected. Multiple imputations were used to compensate for missing data. Strategy A (HSG) has limited value in estimating the risk of tubal pathology. Strategy B (CAT-->HSG) shows that CAT significantly discerns patients with a high versus low risk of tubal pathology, whereas HSG following CAT has no additional value. Strategy C (CAT-->hs-CRP-->HSG) demonstrates that hs-CRP may be valuable in CAT-positive patients only and HSG has no additional value. CAT is proposed as first screening test for tubal factor subfertility. In CAT-negative women, HSG may be performed because of its high specificity and fertility-enhancing effect. In CAT-positive women, hs-CRP seems promising, whereas HSG has no additional value. The position and timing of laparoscopy deserves critical reappraisal.

Pancreatic ductal adenocarcinoma: Risk factors, screening, and early detection

2014-01-01

Pancreatic cancer is the fourth most common cause of cancer-related deaths in the United States, with over 38000 deaths in 2013. The opportunity to detect pancreatic cancer while it is still curable is dependent on our ability to identify and screen high-risk populations before their symptoms arise. Risk factors for developing pancreatic cancer include multiple genetic syndromes as well as modifiable risk factors. Genetic conditions include hereditary breast and ovarian cancer syndrome, Lynch Syndrome, familial adenomatous polyposis, Peutz-Jeghers Syndrome, familial atypical multiple mole melanoma syndrome, hereditary pancreatitis, cystic fibrosis, and ataxia-telangiectasia; having a genetic predisposition can raise the risk of developing pancreatic cancer up to 132-fold over the general population. Modifiable risk factors, which include tobacco exposure, alcohol use, chronic pancreatitis, diet, obesity, diabetes mellitus, as well as certain abdominal surgeries and infections, have also been shown to increase the risk of pancreatic cancer development. Several large-volume centers have initiated such screening protocols, and consensus-based guidelines for screening high-risk groups have recently been published. The focus of this review will be both the genetic and modifiable risk factors implicated in pancreatic cancer, as well as a review of screening strategies and their diagnostic yields. PMID:25170203

Answer questions and earn CME/CNE Screening to detect polyps or cancer at an early stage has been shown to produce better outcomes in colorectal cancer (CRC). Programs with a population-based approach can reach a large majority of the eligible population and can offer cost-effective interventions with the potential benefit of maximizing early cancer detection and prevention using a complete follow-up plan. The purpose of this review was to summarize the key features of population-based programs to increase CRC screening in the United States. A search was conducted in the SCOPUS, OvidSP, and PubMed databases. The authors selected published reports of population-based programs that met at least 5 of the 6 International Agency for Research on Cancer (IARC) criteria for cancer prevention and were known to the National Colorectal Cancer Roundtable. Interventions at the level of individual practices were not included in this review. IARC cancer prevention criteria served as a framework to assess the effective processes and elements of a population-based program. Eight programs were included in this review. Half of the programs met all IARC criteria, and all programs led to improvements in screening rates. The rate of colonoscopy after a positive stool test was heterogeneous among programs. Different population-based strategies were used to promote these screening programs, including system-based, provider-based, patient-based, and media-based strategies. Treatment of identified cancer cases was not included explicitly in 4 programs but was offered through routine medical care. Evidence-based methods for promoting CRC screening at a population level can guide the development of future approaches in health care prevention. The key elements of a successful population-based approach include adherence to the 6 IARC criteria and 4 additional elements (an identified external funding source, a structured policy for positive fecal occult blood test results and confirmed cancer

Objective The rates of participation in the Korean nationwide cervical cancer screening program and the rates of abnormal test results were determined. Methods The database of the National Health Insurance Service (NHIS) was used during the study period (2009–2014). Results The participation rate increased from 41.10% in 2009 to 51.52% in 2014 (annual percentage change, 4.126%; 95% confidence interval [CI]=2.253–6.034). During the study period, women ≥70 years of age had the lowest rate of participation (range, 21.7%–31.9%) and those 30–39 years of age the second-lowest (27.7%–44.9%). The participation rates of National Health Insurance beneficiaries (range, 48.6%–52.5%) were higher than those of Medical Aid Program (MAP) recipients (29.6%–33.2%). The rates of abnormal results were 0.65% in 2009 and 0.52% in 2014, with a decreasing tendency in all age groups except the youngest (30–39 years). Every year the abnormal result rates tended to decrease with age, from the age groups of 30–39 years to 60–69 years but increased in women ≥70 years of age. The ratio of patients with atypical squamous cells of undetermined significance compared with those with squamous intraepithelial lesions increased from 2.71 in 2009 to 4.91 in 2014. Conclusion Differences related to age and occurring over time were found in the rates of participation and abnormal results. Further efforts are needed to encourage participation in cervical cancer screening, especially for MAP recipients, elderly women and women 30–39 years of age. Quality control measures for cervical cancer screening programs should be enforced consistently. PMID:28657224

Bronchiectasis is one of the common chronic respiratory diseases and associated with respiratory morbidity and mortality. However, neither its prevalence nor its etiology is well-defined. We aimed to estimate the prevalence and risk factors of bronchiectasis in adults. In a retrospective study, we analyzed radiologic findings on chest computed tomography (CT) images performed as part of a health-screening program. From January to December 2008, 1,409 (24.6%) of 5,727 participants in the screening program of a health promotion center at a university hospital underwent chest CT scans based on the subject's decision. Bronchiectasis was diagnosed, if there was abnormal bronchial dilatation in any area of both lungs on chest CT. Respiratory symptoms, smoking status, and past medical history were also analyzed to define clinical characteristics and risk factors of bronchiectasis. Of 1,409 patients (aged 23-86 years), who were screened for respiratory diseases using chest CT for one year in a health promotion center, 129 patients (9.1%) were diagnosed with bronchiectasis. The prevalence of bronchiectasis was higher in females than in males (11.5% vs. 7.9%, p = 0.022) and increased with age. Respiratory symptoms were reported in 53.7% of subjects. Previous history of tuberculosis (TB) (OR 4.61, 95% CI 2.39-8.88, p = 0.001) and age (OR 2.49, 95% CI 1.56-3.98, p = 0.001) were significantly associated with bronchiectasis. This retrospective analysis of chest CT findings in health screening examinees revealed a very high prevalence of bronchiectasis in adults. Previous TB infection is one of the major causes of bronchiectasis.

The Centers for Disease Control and Prevention (CDC) established and supported a 4-year Colorectal Cancer Screening Demonstration Program (CRCSDP) from 2005 to 2009 for low-income, under- or uninsured men and women aged 50-64 at 5 sites in the United States. A multiple methods evaluation was conducted including 1) a longitudinal, comparative case study of program implementation, 2) the collection and analysis of client-level screening and diagnostic services outcome data, and 3) the collection and analysis of program- and patient-level cost data. Several themes emerged from the results reported in the series of articles in this Supplement. These included the benefit of building on an existing infrastructure, strengths and weakness of both the 2 most frequently used screening tests (colonoscopy and fecal occult blood tests), variability in costs of maintaining this screening program, and the importance of measuring the quality of screening tests. Population-level evaluation questions could not be answered because of the small size of the participating population and the limited time frame of the evaluation. The comprehensive evaluation of the program determined overall feasibility of this effort. Critical lessons learned through the implementation and evaluation of the CDC's CRCSDP led to the development of a larger population-based program, the CDC's Colorectal Cancer Control Program (CRCCP). © 2013 American Cancer Society.

Newborn screening programs collectively administer the largest genetic testing initiative in the United States. The redress of grievances is an important mechanism for consumers to provide input into clinical and public health programs. In this study, we evaluated mechanisms for addressing consumer grievances in newborn screening programs. To do this, we surveyed all 50 state plus the District of Columbia newborn screening programs by questionnaire regarding protocols for receipt and redress of problems reported by parents of newborns and ascertained the existence and nature of complaints and how complaints were documented and addressed. Pertinent state and federal legislation and regulation were also reviewed. Six of 49 newborn screening programs reported having formal policies for handling consumer grievances. Four states reported having pertinent legislation or regulation. Thirty-eight of 49 states reported having received complaints from 1993 to 1995. Thirteen of 49 newborn screening programs reported that they actively seek feedback from consumers. Consumer grievances ranged from minor complaints to potentially life-threatening concerns. In general, complaints are managed on an ad hoc basis; formal policies are typically lacking. As newborn screening programs affect a vast number of Americans, a proactive and comprehensive approach, including solicitation of consumer feedback, could benefit both newborn screening programs and the public served by them.

Cervical cancer in Nepal ranks as the first most frequent cancer among women. Primary prevention measures, such as prophylactic vaccines against high risk HPV, are now available. Over time, vaccination will decrease the prevalence of the disease among younger women; however, screening will still be needed. The objective of the study was to assess the cervical cancer screening behavior and its associated factors among women of Nala Village Development Committee (VDC), Kavre. A descriptive cross-sectional study was done to assess the cervical cancer screening behavior among women in 2014. Systematic Random sampling was used to collect the data from a sample of 180 women residing in Nala VDC. A structured interview questionnaire and health belief model scale was used to collect data. Descriptive and inferential statistics (Chi-square test) was used for data analysis using SPSS version 16 program. Minority (18.3%) of the respondents had cervical cancer screening behavior. Education level of the respondents was significantly associated with cervical cancer screening behavior (p < 0.05). Age, parity, perceived susceptibility, perceived benefits, and perceived barriers had no significant association with cervical cancer screening behavior. This study shows that cervical cancer screening behavior was satisfactory. The findings of the study indicate a significant association between cervical cancer screening behavior and education level of the participants. Awareness campaigns targeting illiterate groups can be conducted in community so that they become motivated towards cervical cancer screening.

AIM: To investigate the outcome and effectiveness of two screening programs, National Cancer Screening Program (NCSP) and opportunistic screening (OS), for the detection of gastric cancer. METHODS: A total of 45  654 subjects underwent upper endoscopy as part of the NCSP or OS at the Chung-Ang University Healthcare System in Korea between January 2007 and December 2010. The study population was comprised of subjects over the age of 40 years. More specifically, subjects who took part in the NCSP were Medicaid recipients and beneficiaries of the National Health Insurance Corporation. Still photographs from the endoscopies diagnosed as gastric cancer were reviewed by two experienced endoscopists. RESULTS: The mean age of the screened subjects was 55 years for men and 54 years for women. A total of 126 cases (0.28%) of gastric cancer were detected from both screening programs; 100 cases (0.3%) from NCSP and in 26 cases (0.2%) from OS. The proportion of early gastric cancer (EGC) detected in NCSP was higher than that in OS (74.0% vs 53.8%, P = 0.046). Among the 34  416 screenees in NCSP, 6585 (19.1%) underwent upper endoscopy every other year as scheduled. Among the 11  238 screenees in OS, 3050 (27.1%) underwent upper endoscopy at least once every two years during the study period. The detection rate of gastric cancer was found to be significantly higher during irregular follow-up than during regular follow-up in both screening programs (0.3% vs 0.2%, P = 0.036). A higher incidence of EGC than advanced gastric cancer was observed during regular follow-up compared with irregular follow-up. CONCLUSION: Compliance to the screening program is more important than the type of screening system used. PMID:23430471

To assess the cost-effectiveness of a community-based patient navigation program to improve cervical cancer screening among Hispanic women 18 or older in San Antonio, Texas. We used a microsimulation model of cervical cancer to project the long-term cost-effectiveness of a community-based patient navigation program compared with current practice. We used program data from 2012 to 2015 and published data from the existing literature as model input. Taking a societal perspective, we estimated the lifetime costs, life expectancy, and quality-adjusted life-years and conducted 2-way sensitivity analyses to account for parameter uncertainty. The patient navigation program resulted in a per-capita gain of 0.2 years of life expectancy. The program was highly cost-effective relative to no intervention (incremental cost-effectiveness ratio of $748). The program costs would have to increase up to 10 times from $311 for it not to be cost-effective. The 3-year community-based patient navigation program effectively increased cervical cancer screening uptake and adherence and improved the cost-effectiveness of the screening program for Hispanic women 18 years or older in San Antonio, Texas. Future research is needed to translate and disseminate the patient navigation program to other socioeconomic and demographic groups to test its robustness and design.

Assessment of the efficacy of a hearing screening program for college students.

2013-01-01

The Towson University (TU) Speech-Language-Hearing Center (SLHC) conducts annual hearing screenings for college students entering education or health-care professions. Hearing is screened in therapy rooms, and students who fail the screening are rescreened in a sound-treated booth. Students who fail the rescreening are referred for a comprehensive audiological assessment, which is offered at no cost to students at the SLHC. The purpose of this study was to examine the efficacy of the hearing screening program, to report trends in hearing screening statistics for the college student population, and to make recommendations regarding ways universities can optimize hearing screening programs. The study included retrospective and prospective portions. Hearing screening records were reviewed from 1999 to 2011. The prospective study involved recruiting students to participate in diagnostic testing following the hearing screening and measuring background noise levels in the therapy rooms. Hearing screening records from 1999 to 2011 were reviewed. In addition, during the three-day fall 2011 hearing screenings, 80 students were selected to participate in diagnostic testing. Data from the retrospective review were used to determine positive predictive value (PPV) between screening and rescreening. Return rates were also examined. For the prospective study, pure tone threshold results were compared to screening results to determine sensitivity, specificity, and PPV. The retrospective file review indicated that the hearing screening in the therapy room had poor PPV compared with the rescreening in the sound booth. Specifically, if a student failed the screening, they had only a 49% chance of failing the rescreening. This may have been due to background noise, as the prospective study found noise levels were higher than allowed by American National Standards Institute (ANSI) standard. Only a third of students referred for diagnostic testing from 1999 to 2010 returned for

In 2005 through 2009, the Centers for Disease Control and Prevention (CDC) funded 5 sites to implement a colorectal cancer screening program for uninsured, low-income populations. These 5 sites composed a demonstration project intended to explore the feasibility of establishing a national colorectal cancer screening program through various service delivery models. A longitudinal, multiple case study was conducted to understand and document program implementation processes. Using metaphor as a qualitative analytic technique, evaluators identified stages of maturation across the programmatic life cycle. Analysis rendered a working theory of program development during screening implementation. In early stages, program staff built relationships with CDC and local partners around screening readiness, faced real-world challenges putting program policies into practice, revised initial program designs, and developed new professional skills. Midterm implementation was defined by establishing program cohesiveness and expanding programmatic reach. In later stages of implementation, staff focused on sustainability and formal program closeout, which prompted reflection about personal and programmatic accomplishments. Demonstration sites evolved through common developmental stages during screening implementation. Findings elucidate ways to target technical assistance to more efficiently move programs along their maturation trajectory. In practical terms, the time and cost associated with guiding a program to maturity may be potentially shortened to maximize return on investment for both organizations and clients receiving service benefits. © 2013 American Cancer Society.

The objective of this study was to characterise the effects of antenatal inflammatory factors and maternal therapies on neonatal hearing screen outcomes in very low birthweight infants. We conducted a retrospective study of a cohort of infants <33 weeks' gestational age and <1501 g birth weight prospectively enrolled between 1999 and 2003 for whom placental pathology, cord blood interleukin (IL) 6, IL-1ß, tumour necrosis factor-α and neonatal hearing screen results were available. Of 289 infants with documented hearing screen results, 244 (84%) passed and 45 (16%) failed the hearing screen (unilateral, N=25 (56%); bilateral, N=20 (44%)). In the final logistic model, the fetal inflammatory response syndrome defined as the presence of fetal vasculitis and/or cord serum IL-6>18.2 pg/mL was the factor with greatest risk for hearing screen failure (OR 3.62, 95% CI 1.38 to 9.5). A patent ductus arteriosus treated with indomethacin significantly increased the risk (OR 3.3, 95% CI 1.3 to 8.26), while combined maternal steroid and magnesium sulfate exposure (0.37, 95% CI 0.11 to 0.81) reduced the risk for hearing screen failure. Intrauterine infection with a fetal inflammatory response is a risk factor for neonatal hearing loss while maternal therapies significantly reduced the risk of neonatal hearing loss in very low birthweight infants.

Early detection is considered to improve the prognosis of cutaneous melanoma. The value of population-based screening for melanoma, however, is still controversial. The aim of this study was to evaluate the predictive power of established risk factors in the setting of a population-based screening and to provide empirical evidence for potential risk stratifications. We reanalyzed data (including age, sex, risk factors, and screening results) of 354 635 participants in the Skin Cancer Research to provide Evidence for Effectiveness of Screening in Northern Germany project conducted in the German state of Schleswig-Holstein (2003-2004). In multivariable analysis, atypical nevi [odds ratio (OR): 17.4; 95% confidence interval (CI): 14.4-20.1], personal history of melanoma (OR: 5.3; 95% CI: 3.6-7.6), and multiple (≥40) common nevi (OR: 1.3; 95% CI: 1.1-1.6) were associated with an increased risk of melanoma detection. Family history and congenital nevi were not significantly associated with melanoma detection in the Skin Cancer Research to provide Evidence for Effectiveness of Screening in Northern Germany population. The effects of several risk-adapted screening strategies were evaluated. Hypothesizing a screening of individuals aged more than or equal to 35 years, irrespective of risk factors (age approach), the number needed to screen is 559 (95% CI: 514-612), whereas a screening of adults (aged ≥20) with at least one risk factor (risk approach) leads to an number needed to screen of 178 (95% CI: 163-196). Converted into one screen-detected melanoma, the number of missed melanomas is 0.15 (95% CI: 0.12-0.18) with the age approach and 0.22 (95% CI: 0.19-0.26) with the risk approach. The results indicate that focusing on individuals at high risk for melanoma may improve the cost-effectiveness and the benefit-to-harm balance of melanoma screening programs.

According to recent statistics, the breast cancer rate is growing fast in developing countries. In North West Iran, the incidence of breast cancer after esophageal and gastric cancers has the highest rate. Previous studies have also indicated that women in this region show reluctance to do breast cancer screening. There is a great need for change to promote breast cancer screening among women. Social marketing is a discipline that uses the systematic application of commercial marketing techniques to promote the adoption of behavior by the target audience. In the present qualitative study, thirty-two women with breast cancer were interviewed about their experiences of breast cancer screening. A semi-structured interview guide was designed to elicit information specific to the 4 P's in social marketing. Three main categories emerged from the analysis: price, service and promotion. Subcategories related to these main categories included factors effective in increasing and decreasing cost of screening, current and desirable features of screening services, and weakness of promotion. Screening programs should be designed to be of low cost, to meet patients' needs and should be provided in suitable places. Furthermore, it is essential that the cultural beliefs of society be improved through education. It seems necessary to design an executive protocol for breast cancer screening at different levels of primary health care to increase the women's willingness to undergo screening.

To compare breast cancer cumulative incidence, time evolution and stage at diagnosis between participants and non-participant women in a population-based screening program. Cohort study of breast cancer incidence in relation to participation in a population screening program. The study population included women from the target population of the screening program. The source of information for diagnostics and stages was the population-based cancer registry. The analysis period was 1999-2010. The Relative Risk for invasive, in situ, and total cancers diagnosed in participant women compared with non-participants were respectively 1.16 (0.94-1.43), 2.98 (1.16-7.62) and 1.22 (0.99-1.49). The Relative Risk for participants versus non-participants was 2.47 (1.55-3.96) for diagnosis at stagei, 2.58 (1.67-3.99) for T1 and 2.11 (1.38-3.23) for negative lymph node involvement. The cumulative incidence trend had two joint points in both arms, with an Annual Percent of Change of 92.3 (81.6-103.5) between 1999-2001, 18.2 (16.1-20.3) between 2001-2005 and 5.9 (4.0-7.8) for the last period in participants arm, and 72.6 (58.5-87.9) between 1999-2001, 12.6 (7.9-17.4) between 2001-2005, and 8.6 (6.5-10.6) in the last period in the non-participant arm. Participating in the breast cancer screening program analyzed increased the in situ cumulative cancer incidence, but not the invasive and total incidence. Diagnoses were earlier in the participant arm. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

For efficient transgenic herd expansion, only the transgenic animals that possess the ability to transmit transgene into next generation are considered for breeding. However, for transgenic pig, practically lacking a pre-breeding screening program, time, labor and money is always wasted to maintain non-transgenic pigs, low or null transgenic transmission pigs and the related fruitless gestations. Developing a pre-breeding screening program would make the transgenic herd expansion more economical and efficient. In this technical report, we proposed a three-step pre-breeding screening program for transgenic boars simply through combining the fluorescence in situ hybridization (FISH) assay with the common pre-breeding screening workflow. In the first step of screening, combined with general transgenic phenotype analysis, FISH is used to identify transgenic boars. In the second step of screening, combined with conventional semen test, FISH is used to detect transgenic sperm, thus to identify the individuals producing high quality semen and transgenic sperm. In the third step of screening, FISH is used to assess the in vitro fertilization embryos, thus finally to identify the individuals with the ability to produce transgenic embryos. By this three-step screening, the non-transgenic boars and boars with no ability to produce transgenic sperm or transgenic embryos would be eliminated; therefore only those boars could produce transgenic offspring are maintained and used for breeding and herd expansion. It is the first time a systematic pre-breeding screening program is proposed for transgenic pigs. This program might also be applied in other transgenic large animals, and provide an economical and efficient strategy for herd expansion.

Studies done in the mid-1970s documented increased risk for respiratory cancer and leukemia among employees in a chemical company manufacturing plant where chloromethyl ethers were used in production from 1948 to 1971. In the late 1980s, the company informed current and former employees about the results of follow-up studies which showed a moderation of risk of respiratory cancer and leukemia. New data showing elevated rates of mortality from colorectal, prostate, bladder, and pancreatic cancer in the population were also reported. Via mailed correspondence, the company made a no-cost program of colorectal and prostate cancer screening available to employees upon request; and information about bladder and pancreatic cancer was made available. Thirteen percent of employees in the population indicated interest in colorectal and prostate cancer screening (response). Thirty-one percent of these responders were screened (adherence). Multivariate analyses showed that education and length of employment in the plant were positively associated with response. Being white was positively associated with response for younger workers; while among older workers being male was positively associated with response. In terms of adherence, we found that older, more highly educated workers were more likely to have a screening examination. Findings indicate that employee participation in workplace-sponsored colorectal and prostate cancer screening can vary according to worker sociodemographic factors and length of employment in areas of potential exposure.

In 1999, the Korean government introduced the National Cancer Screening Program (NCSP) to increase the cancer-screening rate, particularly among the low-income population. This study investigates how the NCSP has decreased both relative and absolute income inequalities in the uptake of cancer screening in South Korea. A nationally representative cross-sectional repeated data from the Korea National Health and Nutrition Examination Survey 1998-2012, managed by the Ministry of Health and Welfare, was used to assess changes over time and the extent of discontinuity at the NCSP-recommended initiation age in the uptake of screening for breast, colorectal, and gastric cancers across income quartiles. Relative inequalities in the uptake of screening for all cancers decreased significantly over the policy period. Absolute inequalities did not change for most cancers, but marginally increased from 9 to 14% points in the uptake of screening for colorectal cancer among men. At the recommended initiation age, absolute inequalities did not change for breast and colorectal cancers but increased from 5 to 16% points for gastric cancer, for which relative inequality significantly decreased. The NCSP, which reduced out-of-pocket payment, may not decrease absolute gap although it leads to overall increases in the uptake of cancer screening and decreases in relative inequalities. Further investigations are needed to understand barriers that prevent the low-income population from attending cancer screening.

Besides participation in the primary prevention, screening as secondary prevention is an important requirement for primary care services. The effect of this work is influenced by the characteristics of individual primary care practices and doctors' screening habits, as well as by the regulation of screening processes and available financial resources. Between 1999 and 2009, a managed care program was introduced and carried out in Hungary, financed by the government. This financial support and motivation gave the opportunity to increase the number of screenings. 4,462 patients of 40 primary care practices were screened on the basis of SCORE risk assessment. The results of the screening were compared on the basis of two groups of patients, namely: those who had been pre-screened (pre-screening method) for known risk factors in their medical history (smoking, BMI, age, family cardiovascular history), and those randomly screened. The authors also compared the mortality data of participating primary care practices with the regional and national data. The average score was significantly higher in the pre-screened group of patients, regardless of whether the risk factors were considered one by one or in combination. Mortality was significantly lower in the participating primary practices than had been expected on the basis of the national mortality data. This government-financed program was a big step forward to establish a proper screening method within Hungarian primary care. Performing cardiovascular screening of a selected target group is presumably more appropriate than screening within a randomly selected population. Both methods resulted in a visible improvement in regional mortality data, though it is very likely that with pre-screening a more cost-effective selection for screening may be obtained.

Cancer-related distress has been endorsed as the sixth vital sign by many international cancer organizations, and some countries such as Canada have implemented national screening for distress programs. The completion of a screening tool is an important first step in improving responsiveness to cancer-related distress, but screening must be followed with skilled supportive care to make a difference in patient-reported outcomes. Our objective was to create a web-based education program to support nurses and other frontline staff in providing an initial response to screening results. To address screening and supportive care learning needs, the Canadian Association of Psychosocial Oncology (CAPO), with support from the Canadian Partnership Against Cancer, created a web-based education program as one component of the national screening for distress agenda. The program provides clinically grounded and interactive learning through the use of PowerPoint presentations, video clips of clinical interactions with patients and family members, and test questions. Presentation topics include, for example, strategies for dealing with screening results, managing referrals, and supportive counseling. We employed a matched pairs, pre-post survey design to assess the effect of the education program on confidence in screening and in providing initial supportive care. Our analysis of the first 147 matched pairs to complete the course suggests that satisfaction with the course was high. Statistically significant increases in confidence in relation to screening for distress and assessing distress, and in providing initial supportive care, were evident. Our ongoing experience with CAPO's Interprofessional Psychosocial Oncology Distance Education (IPODE) project (www.ipode.ca) project suggests that healthcare professionals value web-based learning for its accessibility and convenience. Such programs appear to offer excellent opportunities for cost-effective education that supports practice

To study the factors affecting a neurodevelopmental status of children with congenital hypothyroidism, diagnosed on national screening program. The study was performed in the Pediatric Endocrinology Department of Dr. Behcet Uz Children's Hospital between May 2012 and May 2013. Children with congenital hypothyroidism, aged between 24 and 36 months, diagnosed by national screening program were included in the study group. Healthy subjects at the same age group consisted of the control group. For the neurodevelopmental evaluation, Bayley Scale of Infant Development- II (BSID-II) was used. Factors possibly effective on neurodevelopment were evaluated. 42 patients and 40 healthy children (mean (SD) age, 29.4 (3.7) and 29.2 (3.5), respectively were included in the study. The mean MDI score [92.6 (7.07) vs 97.1 (9.69), P=0.14)] and the mean PDI score [97.8 (15.68) vs 99.1 (10.57), P=0.66)] in the study group and control group were not significantly different. Among the patient, 4.6% and 4.7% children were moderately retarded as per the MDI scores and PPI scores, respectively. The sex, socioeconomic status, birth weight, screening levels of TSH, severity of the congenital hypothyroidism, initiation time and the dosage of thyroid hormone replacement, length of the normalization period of TSH, and adherence to treatment were not found to affect the MDI and PDI scores of the patients. Some children with congenital hypothyrodism may have mild to moderate neurodevelopmental retardation, despite the early diagnosis and treatment, and thus need to be under regular follow-up for neurodevelopmental status.

Acromegaly is a rare disease with a large burden due its associated comorbidities and the life-long management required. Since the occurrence and severity of associated complications are related to length of exposure to the excess growth hormone seen in acromegaly, early diagnosis is imperative. The delay in diagnosis, however, can be long, and may be the result of a lack of disease awareness and screening programs. Since acromegaly is an uncommon disease, finding ways to increase recognition and diagnosis that would permit early detection in a logical and cost-effective manner could be a challenge. We conducted a retrospective literature review for information relating to the screening and diagnosis of acromegaly using PubMed. The aim was to assess whether an acromegaly-screening program in Latin America (and elsewhere) would be both of use and be feasible. An earlier diagnosis allows earlier initiation of treatment, such as surgery and/or drugs, which leads to more successful disease management (biochemical control) and better outcomes. Since the delay in diagnosis can be long, we believe that clear opportunities exist for earlier (and increased) detection of acromegaly. This can be achieved by increasing disease awareness for earlier recognition of symptoms and by using targeted screening (rather than mass screening) programs.

Participation in established cancer screening programs remains variable. Therefore, a renewed focus on how to increase screening uptake, including addressing structural barriers such as time, travel, and cost is needed. One approach could be the provision of combined cancer screening, where multiple screening tests are provided at the same time and location (essentially a 'One Stop' screening shop). This cohort study explored both cancer screening behavior and the acceptability of a combined screening approach. Participants of the North Western Adelaide Health Study (NWAHS), South Australia were invited to participate in a questionnaire about cancer screening behaviors and the acceptability of a proposed 'One Stop' cancer screening shop. Data were collected from 10th August 2015 to 18th January 2016, weighted for selection probability, age, and sex and analyzed using descriptive and multivariable logistic regression analysis. 1,562 people, 52% female (mean age 54.1 years ± 15.2) participated. Reported screening participation was low, the highest being for Pap Smear (34.4%). Common reasons for screening participation were preventing sickness (56.1%, CI 53.2-59.0%), maintaining health (51%, CI 48-53.9%), and free program provision (30.9%, CI 28.2-33.6%). Females were less likely to state that screening is not beneficial [OR 0.37 (CI 0.21-0.66), p  < 0.001] and to cite sickness prevention [OR 2.10 (CI 1.46-3.00), p  < 0.001] and free program [OR 1.75 (CI 1.22-2.51), p  < 0.003] as reasons for screening participation. Of those who did not participate, 34.6% (CI 30.3-39.1%) stated that there was nothing that discouraged them from participation, with 55- to 64-year olds [OR 0.24 (CI 0.07-0.74), p  < 0.04] being less likely to cite this reason. 21% (CI 17.2-24.8%) thought they did not need screening, while a smaller proportion stated not having time (6.9%, CI 4.9-9.7%) and the costs associated with screening (5.2%, CI 3.5-7.7%).

Objective: To determine the prevalence of excessive screen time and to analyze associated factors among adolescents. Methods: This was a cross-sectional school-based epidemiological study with 2874 high school adolescents with age 14-19 years (57.8% female) from public and private schools in the city of João Pessoa, PB, Northeast Brazil. Excessive screen time was defined as watching television and playing video games or using the computer for more than 2 h/day. The associated factors analyzed were: sociodemographic (gender, age, economic class, and skin color), physical activity and nutritional status of adolescents. Results: The prevalence of excessive screen time was 79.5% (95%CI 78.1-81.1) and it was higher in males (84.3%) compared to females (76.1%; p<0.001). In multivariate analysis, adolescent males, those aged 14-15 year old and the highest economic class had higher chances of exposure to excessive screen time. The level of physical activity and nutritional status of adolescents were not associated with excessive screen time. Conclusions: The prevalence of excessive screen time was high and varied according to sociodemographic characteristics of adolescents. It is necessary to develop interventions to reduce the excessive screen time among adolescents, particularly in subgroups with higher exposure. PMID:26298661

We examined trends in colorectal cancer (CRC) screening (fecal occult blood test (FOBT), colonoscopy, and flexible sigmoidoscopy (FS)) and differences in CRC screening by income in a population with an organized CRC screening program and universal health-care coverage. Individuals who had an FOBT, colonoscopy, or FS were identified from the provincial Physician Claims database and the population-based colon cancer screening registry. Trends in age-standardized rates were determined. Logistic regression was performed to explore the association between CRC screening and income quintiles by year. Up-to-date CRC screening (FOBT, colonoscopy, or FS) increased over time for men and women, all age groups, and all income quintiles. Up-to-date CRC screening was very high among 65- to 69- and 70- to 74-year-olds (70% and 73%, respectively). There was a shift toward the use of an FOBT for CRC screening for individuals in the lower income quintiles. The disparity in colonoscopy/FS coverage by income quintile was greater in 2012 than in 1995. Overall, there was no reduction in disparities by income in up-to-date CRC screening nor did the rate of increase in up-to-date CRC screening or FOBT use change after the introduction of the organized provincial CRC screening program. CRC screening is increasing over time for both men and women and all age groups. However, a disparity in up-to-date CRC screening by income persisted even with an organized CRC screening program in a universal health-care setting.

Abstract Background The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides low-income, uninsured women with screening and diagnostic services for breast and cervical cancer. Our study was conducted to describe the demographic and practice characteristics of participating and nonparticipating physicians, as well as their beliefs, adoption of new screening technologies, and recommendations for breast and cervical cancer screening. Methods From a 2006–2007 nationally representative survey, we identified 1,111 practicing primary care physicians who provide breast and cervical cancer screenings and assessed their recommendations using clinical vignettes related to screening initiation, frequency, and cessation. Responses of physicians participating in the NBCCEDP were compared with those from nonparticipating physicians. Results Of the physicians surveyed, 15% reported participation in the NBCCEDP, 65% were not participants, and 20% were not sure or did not respond to this question. Program physicians were significantly more likely to practice in multispecialty settings, in a rural location, and in a hospital or clinic setting and had more patients who were female and insured by Medicaid or uninsured compared with nonprogram physicians. Beliefs about the effectiveness of screening tools or procedures in reducing breast or cervical cancer mortality were similar by program participation. Adoption of new technologies, including digital mammography and human papillomavirus (HPV) testing, and making guideline-consistent recommendations for screening initiation, frequency, and cessation did not differ significantly by program participation. Conclusions Although there may be differences in physician characteristics and practice settings, the beliefs and screening practices for both breast and cervical cancer are similar between program and nonprogram providers.

Colorectal cancer (CRC) is a major health problem in Asia. It has been reported that the Chinese are more susceptible to CRC than many other ethnic groups. Screening for CRC is a cost-effective prevention and control strategy; however, the screening rates among the Chinese are sub-optimal. We conducted a review to identify the factors associated with CRC screening participation among Chinese people. Twenty-two studies that examined the factors related to CRC screening behaviors among the Chinese were identified through five databases. Seven factors were consistently reported to influence CRC screening behaviors in at least one of the studies: socio-demographic characteristics (educational level, health insurance, and knowledge about CRC and its screening); psychological factors (perceived severity of CRC, susceptibility of having CRC, and barriers to screening); and contact with medical provider (physician recommendation). The evidence base for many of these relationships is quite limited. Furthermore, the associations of many factors, including age, gender, income, cancer worry/fear, and self-efficacy with CRC screening behaviors, were mixed or inconsistent across these studies, thereby indicating that more studies are needed in this area.

Evaluate the Neonatal Screening Program of the Health Secretariat of the State of Santa Catarina for sickle-cell disease, from January 2003 to December 2012, regarding program coverage and disease frequency. Descriptive, observational, cross-sectional study with retrospective data collection. The variables analyzed were: number of live births in the State of Santa Catarina; number of screened children; number of children diagnosed with sickle-cell trait and sickle-cell disease; type of sickle-cell disease diagnosed; age at the time of sample collection, ethnicity/skin color, gender, and origin of children with sickle-cell disease. Descriptive measures and frequency tables were used for data analysis. During the study period, there were 848,833 live births and 730,412 samples were screened by the program, resulting in a coverage of 86.0%. There were 6173 samples positive for sickle-cell trait and 39 for sickle-cell disease. Among children with sickle-cell disease, the median age at the time of sample collection was 6 days. Regarding the ethnicity/skin color, 25 (64.1%) children were white, seven were black, and seven others were not specified. The Midwest and the Highland (Planalto Serrano) of Santa Catarina were the regions with the highest incidence of sickle-cell disease. Coverage by the Neonatal Screening Program of Santa Catarina is good, but did not demonstrate an improvement trend over the years. The frequency of sickle-cell disease is low and lower than in the North, Northeast, and Midwest regions. The median age in days at the time of collection is older than the age recommended by the Ministry of Health. Copyright © 2016 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

2008-01-01

Dentists are at the forefront for screening oral cancer. In addition to the well known carcinogenic potential of tobacco and alcohol, betel nut chewing and human papilloma virus are important risk factors in the development of oral cancer. To aid in screening and decreasing morbidity and mortality from oral cancer, a variety of techniques have been developed. These techniques show promise but they require additional investigations to determine their usefulness in oral cancer detection. Dentists need to be well educated and vigilant when dealing with all patients they encounter. Early detection, diagnosis and treatment are critical for the effective management of oral cancers.

The quality of risk factor screening during antenatal consultations in Niger.

Prual, A; Toure, A; Huguet, D; Laurent, Y

2000-03-01

A decade after the first International Conference on Safe Motherhood, maternal mortality remains very high in most West African countries, even in capital cities. The detection of high risk pregnancies, known as the risk approach, during antenatal consultations has been the basis of most maternal and child health programmes over the last decade. The effectiveness of antenatal care as a tool to prevent or predict obstetric complications is being questioned more and more. In addition to the scarcity of reliable data about the predictivity of most risk factors, the quality of the screening must be questioned. The goal of this study was to assess the frequency of risk factors among a sample of pregnant women attending antenatal care in Niger and to assess the quality of the screening of those risk factors. Overall, 330 pregnant women were enrolled in the study. Each woman was examined twice: the first time by a midwife, the second time by one of the authors but without knowledge of the results of the first consultation. Fifty-five percent of pregnant women had at least one risk factor, 31% had more than one. Ninety-one percent of the risk factors were detected at interview. The following risk factors were not systematically searched for by midwives: height (48.5%), blood pressure (43.6%), glycosuria (40.6%), vaginal bleeding (38.2%), oedema (37.3%), parity (17%), age (16%), previous caesarean section (15.2%), previous stillbirth (15.2%) and previous miscarriages (14.8%). This study has shown that, in Niger, the quality of screening for risk factors during antenatal consultation is poor. In the urban settings where this study took place, lack of personnel, lack of equipment, lack of time and poor compliance by women cannot be made responsible for this situation. While screening of these risk factors continues as policy, the quality of screening must be dramatically improved.

Background The E-Screen bioassay can measure the mitogenicity of human serum and thus may be useful as a biomarker in epidemiologic studies of breast cancer. While the assay’s MCF-7 cells are known to proliferate in response to estrogen, the specific determinants of variation in E-Screen activity in human serum samples are poorly understood. We sought to identify serum molecules and patient characteristics associated with serum E-Screen activity among postmenopausal women. Methods Postmenopausal women (N=219) aged 55–70 with no history of postmenopausal hormone use or breast cancer completed a questionnaire and provided a blood sample. Serum was analyzed for E-Screen activity and a variety of molecules including sex hormones, growth factors, and environmental chemicals. Stepwise selection procedures were used to identify correlates of E-Screen activity. Results Serum samples from all women had detectable E-Screen activity, with a median estradiol equivalents value of 0.027 ng/mL and interquartile range of 0.018–0.036 ng/mL. In the final multivariable-adjusted model, serum E-Screen activity was positively associated with serum estradiol, estrone, IGFBP-3, and testosterone levels (p<0.05), as well as body mass index (p=0.03). Serum E-Screen activity was lower among women with higher SHBG (p<0.0001) and progesterone levels (p=0.03). Conclusion Serum E-Screen activity varies according to levels of endogenous estrogens and other serum molecules. Obesity appears to confer additional serum mitogenicity beyond its impact on the measured hormones and growth factors. Impact By capturing mitogenicity due to a variety of patient and serum factors, the E-Screen may provide advantages for use as a biomarker in breast cancer studies. PMID:23588007

To explore possible factors explaining a low participation rate to breast cancer screening for Turkish women living in Antwerp, Belgium, and to develop ways to increase participation rate. The authors used focus group discussions with Turkish women to explore their reasons to participate or not to participate in breast cancer screening. Groups consisted of four to six women. Inclusion criteria were: being female, having a Turkish origin, and age between 50 and 69 years. For each focus group, one Turkish women was invited and asked to invite five other women meeting the inclusion criteria. Three focus group discussions with in total 17 women have taken place. Six women had participated to all consecutive invitations for breast cancer screening. One woman had participated once, but not the next time she was invited. Ten women had never participated to screening mammography, although some of them had undergone diagnostic mammography. In all three focus groups, insufficient knowledge of the Dutch language, the unavailability of a professional interpreter, being careless about healthcare, and a negative influence of the husband, were the main reasons not to participate in breast cancer screening. Invitation letters are not read because they are in a language the woman does not understand. Less frequently mentioned obstacles were being on a holiday or being sick on the day of the scheduled mammography, fear of pain, considering an examination useless when not having any symptoms, being anxious for a positive result, and the physical distance to the screening center. Receiving an invitation in Turkish and knowing that a person speaking Turkish will be available at the screening center were proposed as possible measures to improve participation. The single most important reason why Turkish women living in Antwerp, Belgium, do not participate in breast cancer screening was a language problem; other reasons were a lack of knowledge concerning breast cancer screening and not

We examined the factor structure of the Psychiatric Diagnostic Screening Questionnaire (PDSQ), a 125-item self-report scale that screens for 15 of the most common Axis I psychiatric disorders for which patients seek treatment in outpatient settings. The sample consisted of 2440 psychiatric outpatients. Thirteen factors were extracted. Ten mapped directly onto the DSM-IV diagnosis for which they were designed and one represented suicidal ideation. The remaining two factors reflected closely related disorders: Panic Disorder/Agoraphobia, and Somatization/Hypochondriasis. A psychosis factor was not extracted. Overall, the factor structure of the PDSQ was consistent with the DSM-IV nosology upon which it was developed.

Adapting the Australian system: is an organized screening program feasible in Malaysia?--an overview of cervical cancer screening in both countries.

Cervical cancer is the third most common form of cancer that strikes Malaysian women. The National Cancer Registry in 2006 and 2007 reported that the age standardized incidence (ASR) of cervical cancer was 12.2 and 7.8 per 100,000 women, respectively. The cumulative risk of developing cervical cancer for a Malaysian woman is 0.9 for 74 years. Among all ethnic groups, the Chinese experienced the highest incidence rate in 2006, followed by Indians and Malays. The percentage cervical cancer detected at stage I and II was 55% (stage I: 21.0%, stage II: 34.0%, stage III: 26.0% and stage IV: 19.0%). Data from Ministry of Health Malaysia (2006) showed a 58.9% estimated coverage of pap smear screening conducted among those aged 30-49 years. Only a small percentage of women aged 50-59 and 50-65 years old were screened, 14% and 13.8% coverage, respectively. Incidence of cervical cancer was highest (71.6%) among those in the 60-65 age group (MOH, 2003). Currently, there is no organized population-based screening program available for the whole of Malaysia. A pilot project was initiated in 2006, to move from opportunistic cervical screening of women who attend antenatal and postnatal visits to a population based approach to be able to monitor the women through the screening pathway and encourage women at highest risk to be screened. The project was modelled on the screening program in Australia with some modifications to suit the Malaysian setting. Substantial challenges have been identified, particularly in relation to information systems for call and recall of women, as well as laboratory reporting and quality assurance. A cost-effective locally-specific approach to organized screening, that will provide the infrastructure for increasing participation in the cervical cancer screening program, is urgently required.

Objectives. We examined relationships among organizations in a cancer screening network to inform the development of interventions to improve cancer screening for South Asians living in the Peel region of Ontario. Methods. From April to July 2012, we surveyed decision-makers, program managers, and program staff in 22 organizations in the South Asian cancer screening network in the Peel region. We used a network analytic approach to evaluate density (range = 0%–100%, number of ties among organizations in the network expressed as a percentage of all possible ties), centralization (range = 0–1, the extent of variability in centrality), and node characteristics for the communication, collaboration, and referral networks. Results. Density was similar across communication (15%), collaboration (17%), and referral (19%) networks. Centralization was greater in the collaboration network (0.30) than the communication network (0.24), and degree centralization was greater in the inbound (0.42) than the outbound (0.37) referral network. Diverse organizations were central to the networks. Conclusions. Certain organizations were unexpectedly important to the South Asian cancer screening network. Program planning was informed by identifying opportunities to strengthen linkages between key organizations and to leverage existing ties. PMID:24328613

Congenital cytomegalovirus (CMV) infection is a major cause of sensorineural hearing loss. By law, newborns in Connecticut who fail newborn hearing screening are tested for infection with CMV. This targeted screening is controversial, because most children with congenital CMV infection are asymptomatic, and CMV-related hearing loss can have a delayed onset. Our hospital uses a saliva polymerase chain reaction (PCR) assay (confirmed by a urine PCR assay) to detect CMV. Here, we report the results of the first year of our screening program. We reviewed the medical records of newborns in the Yale New Haven Health System who failed the newborn hearing screening test between January 1 and December 31, 2016. Of 10964 newborns, 171 failed newborn hearing screening, and 3 of these newborns had positive saliva CMV PCR test results. Of these 3 newborns, 2 had positive results on the confirmatory test (for 1 of them the confirmatory test was not performed until the infant was 10 weeks old), and 1 had a negative result on the confirmatory test. Three additional newborns with congenital CMV infection were tested because of clinical indications (1 for ventriculomegaly on prenatal ultrasound and 2 for CMV infection of the mother). Results of audiology follow-up were available for 149 (87.1%) of the 171 newborns who failed newborn hearing screening; 127 (85.2%) had normal results. Our targeted screening program for congenital CMV infection had a low yield. Consideration should be given to other strategies for identifying children at risk of hearing loss as a result of congenital CMV infection. © The Author(s) 2018.

To explore the accessibility of standardized printed information materials of the national Dutch colorectal cancer screening program among low health literate screening invitees and to assess the effect of the information on their knowledge about colorectal cancer and the screening program. Linguistic tools were used to analyze the text and design characteristics. The accessibility, comprehensibility and relevance of the information materials were explored in interviews and in observations (n=25). The effect of the information on knowledge was assessed in an online survey (n=127). The materials employed a simple text and design. However, respondents expressed problems with the amount of information, and the difference between screening and diagnostic follow-up. Knowledge significantly increased in 10 out of 16 items after reading the information but remained low for colorectal cancer risk, sensitivity of testing, and the voluntariness of colorectal cancer screening. Despite intelligible linguistic and design characteristics, screening invitees with low health literacy had problems in accessing, comprehending and applying standard information materials on colorectal cancer screening, and lacked essential knowledge for informed decision-making about participation. To enable equal access to informed decision-making, information strategies need to be adjusted to the skills of low health literate screening invitees. Copyright © 2016 Elsevier Ireland Ltd.

Thalassemia screening program has been implemented for years in Southeast Asia, but no external quality assessment program has been established. We have developed and initiated the proficiency testing (PT) program for the first time in Thailand with the aim to assess the screening performance of laboratory staff and their competency in interpretation of the screening results. Three PT cycles per year were organized. From the first to the third cycle of the PT scheme, a total number of participant laboratories increased from 59 to 67. In each cycle, 2 PT items (assigned as blood samples of the couple) were provided. Performance evaluation was based on the accuracy of screening results, i.e . mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and the dichlorophenolindophenol (DCIP) test for haemoglobin E, including the competency in interpretation of screening results and assessment of foetal risk. Performance was assessed by comparing the participants' result against the assigned value. Of all 3 cycles, most laboratories reported acceptable MCV and MCH values. From the first to the third cycle, incorrect DCIP test and misinterpretation rates were decreased while incorrect risk assessment varied by cycle to cycle. Combining the accuracy of thalassemia screening and the competency in interpretation and risk assessment, approximately half of participants showed excellent performance. Improved performance observed in many laboratories reflects the achievement and benefit of the PT program which should be regularly provided.

To determine the prevalence of excessive screen time and to analyze associated factors among adolescents. This was a cross-sectional school-based epidemiological study with 2,874 high school adolescents with age 14-19 years (57.8% female) from public and private schools in the city of João Pessoa, PB, Northeast Brazil. Excessive screen time was defined as watching television and playing video games or using the computer for more than two hours per day. The associated factors analyzed were: sociodemographic (gender, age, economic class, and skin color), physical activity and nutritional status of adolescents. The prevalence of excessive screen time was 79.5% (95%CI: 78.1-81.1) and it was higher in males (84.3%) compared to females (76.1%; p<0,001). In multivariate analysis, adolescent males, aged 14-15 years old, of higher economic classes had higher chances of exposure to excessive screen time. The level of physical activity and nutritional status of adolescents were not associated with excessive screen time. The prevalence of excessive screen time was high and varied according to sociodemographic characteristics of adolescents. It is necessary to develop interventions to reduce the excessive screen time among adolescents, particularly in subgroups with higher exposure. Copyright © 2015 Sociedade de Pediatria de São Paulo.

McLean, M J; Condon, J R

1999-08-01

A process evaluation of the Northern Territory (NT) mammography program, NT Breast Screen (NTBS), during its initial 18 months of operation. The study was undertaken in Darwin, NT, from December 1994 to May 1996. Clinical outcomes were obtained by reviewing computerised and manual program records to determine waiting times for results, recall rates and cancer detection rates. Client satisfaction was assessed by a questionnaire sent to all women with normal results over a 12-week period. General practitioner satisfaction was assessed by a questionnaire sent to all general practitioners in the region who had one or more clients who had attended the service. During this time, 2,882 screening mammograms were performed; 98 women were recalled for assessment (3.4%). Breast cancer was detected in 10 women (3.5 per 1000 women screened). The program was well accepted by clients and general practitioners. Performance criteria were not met for waiting times for results. NTBS faced challenges because of its small and dispersed population, a lack of local radiologists with mammographic experience and the conflict with other pressing health issues, particularly in Aboriginal health. Despite these challenges, the program functioned effectively during its initial 18 months. Mammography screening programs in isolated areas can function effectively. The constraints encountered by NTBS are likely to apply to similar programs. Issues identified requiring further research are the psychological consequences of long waiting times for results, and the prioritisation of mammography for Aboriginal women.

Breast cancer (BC) continues to be a major cause of morbidity and mortality among women throughout the world and in Iran. Lack of awareness and early detection program in developing country is a main reason for escalating the mortality. The present research was conducted to assess the Iranian women's level of knowledge about breast cancer risk factors, early warning signs, and therapeutic and screening approaches, and their correlated determinants. In a cross-sectional study, 2250 women before participating at a community based screening and public educational program in an institute of cancer research in Isfahan, Iran, in 2012 were investigated using a self-administered questionnaire about risk factors, early warning signs, and therapeutic and screening approaches of BC. Latent class regression as a comprehensive statistical method was used for evaluating the level of knowledge and its correlated determinants. Only 33.2%, 31.9%, 26.7%, and 35.8% of study participants had high awareness levels about screening approaches, risk factors, early warning signs and therapeutic modalities of breast cancer, respectively, and majority had poor to moderate knowledge levels. Most effective predictors of high level of awareness were higher educational qualifications, attending in screening and public educational programs, personal problem, and family history of BC, respectively. Results of current study indicated that the levels of awareness among study population about key elements of BC are low. These findings reenforce the continuing need for more BC education through conducting public and professional programs that are intended to raise awareness among younger, single women and those with low educational attainments and without family history.

Factors affecting reproducibility between genome-scale siRNA-based screens

RNA interference-based screening is a powerful new genomic technology which addresses gene function en masse. To evaluate factors influencing hit list composition and reproducibility, we performed two identically designed small interfering RNA (siRNA)-based, whole genome screens for host factors supporting yellow fever virus infection. These screens represent two separate experiments completed five months apart and allow the direct assessment of the reproducibility of a given siRNA technology when performed in the same environment. Candidate hit lists generated by sum rank, median absolute deviation, z-score, and strictly standardized mean difference were compared within and between whole genome screens. Application of these analysis methodologies within a single screening dataset using a fixed threshold equivalent to a p-value ≤ 0.001 resulted in hit lists ranging from 82 to 1,140 members and highlighted the tremendous impact analysis methodology has on hit list composition. Intra- and inter-screen reproducibility was significantly influenced by the analysis methodology and ranged from 32% to 99%. This study also highlighted the power of testing at least two independent siRNAs for each gene product in primary screens. To facilitate validation we conclude by suggesting methods to reduce false discovery at the primary screening stage. In this study we present the first comprehensive comparison of multiple analysis strategies, and demonstrate the impact of the analysis methodology on the composition of the “hit list”. Therefore, we propose that the entire dataset derived from functional genome-scale screens, especially if publicly funded, should be made available as is done with data derived from gene expression and genome-wide association studies.

Breast screening programs are increasingly controversial, especially regarding two points: the number of breast cancer deaths they avoid, and the problem of over-diagnosis and over-treatment. The French national breast cancer screening program was extended to cover the whole country in 2004. Ten years later it is time to examine the risk/benefit ratio of this program and to discuss the need for change. Like all forms of cancer management, screening must be regularly updated, taking into account the state of the art, new evidence, and uncertainties. All screening providers should keep themselves informed of the latest findings. In the French program, women aged 50-74 with no major individual or familial risk factors for breast cancer are offered screening mammography and clinical breast examination every two years. Images considered non suspicious of malignancy by a first reader are re-examined by a second reader. The devices and procedures are subjected to quality controls. Participating radiologists (both public and private) are required to read at least 500 mammographies per year. The program's national participation rate was 52.7 % in 2012. When individual screening outside of the national program is taken into account (nearly 15 % of women), coverage appears close to the European recommendation of 65 %. Breast cancer mortality has been falling in France by 0.6 % per year for over 30 years, starting before mass screening was implemented, and by 1.5 % since 2005. This decline can be attributed in part to earlier diagnosis and better treatment, so that the specific impact of screening cannot easily be measured. Over-treatment, defined as the detection and treatment of low-malignancy tumors that would otherwise not have been detected in a person's lifetime, is a major negative effect of screening, but its frequency is not precisely known (reported to range from 1 % to 30 %). In view of these uncertainties, it would be advisable to modify the program in order to

Despite the long history of cancer screening in Japan, the participation rates in gastric and colorectal cancer screenings have not increased. Strategies for improving the participation rates have been proposed, but differences in their effects among different age groups remain unclear. The Japanese government conducted a national survey in all municipalities in Japan in 2010 to investigate whether the implementation of promotion strategies increased participation in cancer screening. We investigated the association between age factors and strategies for promoting participation in cancer screening based on this national survey. Multiple regression analysis with generalized linear model was performed using the participation rates in gastric and colorectal cancer screenings as dependent variables, and the following strategies for promoting participation as independent variables: 1) personal invitation letters, 2) household invitation letters, 3) home visits by community nurses, 4) screenings in medical offices, and 5) free cancer screening programs. One thousand six hundred thirty nine municipalities for gastric cancer screening and 1666 municipalities for colorectal cancer screening were selected for the analysis. In gastric and colorectal cancer screenings, the participation rates of individuals aged 60-69 years was higher than those of other age groups. Personal and household invitation letters were effective promotion strategies for all age groups, which encouraged even older people to participate in gastric and colorectal cancer screenings. Screening in medical offices and free screenings were not effective in all age groups. Home visits were effective, but their adoption was limited to small municipalities. To clarify whether promotion strategies can increase the participation rate in cancer screening among different age groups, 5 strategies were assessed on the basis of a national survey. Although personal and household invitation letters were effective

To explore the performance of a protocol combining fecal immunochemical test (FIT) and a high-risk factor questionnaire (HRFQ) for selecting patients requiring colonoscopy as part of a population-based colorectal cancer (CRC) screening program in China. From 2015 to 2016, we conducted a CRC screening program for all residents aged 45 years or older in Tianhe District, Guangzhou City, China. Participants underwent an FIT and received an HRFQ as part of primary screening. Those with positive FIT and/or HRFQ results were considered to be at high risk and were recommended to undergo colonoscopy. A total of 10 074 subjects were recruited and enrolled in the screening program. In the enrolled population, 17.5% had positive FIT results and 19.4% had positive HRFQ results. Of those recommended to undergo diagnostic colonoscopy, 773 did so. The screening method's overall positive predictive value (PPV) was 4.9% for non-adenomatous polyps, 11.4% for low-risk adenomas (LRAs), 15.9% for high-risk adenomas (HRAs) and 1.6% for CRC. The PPVs of positive FIT results for non-adenomatous polyps, LRAs, HRAs and CRC were 5.2%, 15.9%, 22.5% and 2.5%, respectively. The PPVs of positive HRFQ results for non-adenomatous polyps, LRA, HRA and CRC were 4.1%, 10.2%, 14.3% and 1.4%, respectively. The PPVs associated with combined positive FIT and HRFQ results for non-adenomatous polyps, LRAs, HRAs and CRC were 4.5%, 16.4%, 23.7% and 2.8%, respectively. Our results suggest that this two-step CRC screening strategy, involving a combination of FIT and HRFQ followed by colonoscopy, is useful to identify early-stage CRC. The high detection rates and PPVs for CRC and adenomas encourage this strategy's use in ongoing screening programs.

As part of the development of a system for the screening of refractive error in Thai children, this study describes the accuracy and feasibility of establishing a program conducted by teachers. To assess the accuracy and feasibility of screening by teachers. A cross-sectional descriptive and analytical study was conducted in 17 schools in four provinces representing four geographic regions in Thailand. A two-staged cluster sampling was employed to compare the detection rate of refractive error among eligible students between trained teachers and health professionals. Serial focus group discussions were held for teachers and parents in order to understand their attitude towards refractive error screening at schools and the potential success factors and barriers. The detection rate of refractive error screening by teachers among pre-primary school children is relatively low (21%) for mild visual impairment but higher for moderate visual impairment (44%). The detection rate for primary school children is high for both levels of visual impairment (52% for mild and 74% for moderate). The focus group discussions reveal that both teachers and parents would benefit from further education regarding refractive errors and that the vast majority of teachers are willing to conduct a school-based screening program. Refractive error screening by health professionals in pre-primary and primary school children is not currently implemented in Thailand due to resource limitations. However, evidence suggests that a refractive error screening program conducted in schools by teachers in the country is reasonable and feasible because the detection and treatment of refractive error in very young generations is important and the screening program can be implemented and conducted with relatively low costs.

Noncommunicable disease (NCDs), psychological, substance use disorders, and stress-related issues have been less understood in Indian industrial settings. Systems for screening and early identification of the above have not been integrated in workplaces, nor there is a strong regulatory backing for the same. To explore the feasibility of integrating mental health and select NCD risk factor screening with the periodical medical examination of employees. To identify proportion of employees with select NCD risk factors and symptoms suggestive of mental health problems. Around 10% of employees from a leading motor industry in Bangalore, (706) participated in this cross-sectional voluntary screening program. This screening was conducted as a part of their annual medical examination. A mixed method of self-report and interview administered technique was adopted for the same. Descriptive statistical methods (proportions, median, mean, and standard deviation (SD)) and Chi-square test of significance. Screening revealed the following; tobacco use (18%), alcohol use (57%), perceived work stress (10%), and obesity (3%). Nearly 23% screened positive for psychological distress. Time consumed for this assessment was 1-5 min. Initial attempts point out that it is feasible to integrate screening for mental health, substance use, and NCD risk factors in periodic medical examination using a combination of self-report and interview-administered method, though further detailed assessments for confirmation is necessary.

Colorectal cancer (CRC) is one of the leading causes of cancer mortality in Belgium. In Flanders (Belgium), a population-based screening program with a biennial immunochemical faecal occult blood test (iFOBT) in women and men aged 56-74 has been organised since 2013. This study assessed the cost-effectiveness and budget impact of the colorectal population-based screening program in Flanders (Belgium). A health economic model was conducted, consisting of a decision tree simulating the screening process and a Markov model, with a time horizon of 20years, simulating natural progression. Predicted mortality and incidence, total costs, and quality-adjusted life-years (QALYs) with and without the screening program were calculated in order to determine the incremental cost-effectiveness ratio of CRC screening. Deterministic and probabilistic sensitivity analyses were conducted, taking into account uncertainty of the model parameters. Mortality and incidence were predicted to decrease over 20years. The colorectal screening program in Flanders is found to be cost-effective with an ICER of 1681/QALY (95% CI -1317 to 6601) in males and €4,484/QALY (95% CI -3254 to 18,163). The probability of being cost-effective given a threshold of €35,000/QALY was 100% and 97.3%, respectively. The budget impact analysis showed the extra cost for the health care payer to be limited. This health economic analysis has shown that despite the possible adverse effects of screening and the extra costs for the health care payer and the patient, the population-based screening program for CRC in Flanders is cost-effective and should therefore be maintained.

The purpose of this study was to evaluate the contributions and limitations of the cervical cancer screening test with accuracy in Korea. This was a retrospective observational study. The study population consisted of all participants who underwent cervical cancer screening test from 2009 to 2014. The data were obtained from National Health Information Database (NHID) which represents medical use records of most Koreans. As the indices for contributions and limitations of the screening test, crude detection rate, incidence rate of interval cancer, sensitivity, specificity, and positive predictive value were used. The crude detection rate of screening test per 100,000 participants increased from 100.7 in 2009 to 102.1 in 2014. The incidence rate of interval cancer per 100,000 negatives decreased from 13.0 in 2009 to 10.2 in 2014. The sensitivities of screening test were 88.7% in 2009 and 91.2% in 2014, and the specificities were 98.5% in 2009 and 97.7% in 2014. The positive predictive value of screening decreased from 6.2% in 2009 to 4.3% in 2014. The Korean national cervical cancer screening program has improved in accuracy and has contributed to detection of early stage of cervical cancer over the years. Along with efforts to promote participation in cancer screening programs, quality control over the screening program should be enhanced. Copyright © 2018. Published by Elsevier B.V.

Objective: To estimate the cervical and breast cancer screening coverage and related factors among women aged 35-69 years who were in the National Cervical and Breast Screening Program, to provide evidence for improving cervical and breast cancer control and prevention strategy. Methods: Data used in this study were abstracted from the 2013 Chinese Chronic Diseases and Risk Factors Surveillance Program. A total of 66 130 women aged 35-64 years and 72 511 women aged 35-69 years were included for this study. Weighted prevalence, (with 95% confidence interval, CI ) was calculated for complex sampling design. Rao-Scott χ (2) method was used to compare the screening coverage among subgroups. A random intercept equation which involved the logit-link function, was fitted under the following five levels: provincial, county, township, village and individual. Fix effects of all explanatory variables were converted into OR with 95% CI . Results: In 2013, 26.7% (95% CI : 24.6%-28.9%) of the 35-64 year-old women reported that they ever had been screened for cervical cancer and 22.5% (95% CI : 20.4%-24.6%) of the 35-69 year-olds had ever undergone breast cancer screening. Lower coverage was observed among women residing in rural and central or western China than those in urban or eastern China ( P <0.000 1). The coverage among women aged 50 years or older was substantially lower than those aged 35-49 years. Those who were with low education level, unemployed, low household income and not covered by insurance, appeared fewer number on this cervical or breast cancer screening program ( P <0.000 1). Women living in rural and western China were having less chance of receiving the breast cancer screening ( P <0.05), but the difference was not statistically significant. Conclusion: It is essential to strengthen the community-based cervical and breast cancer screening programs, in order to increase the coverage. More attention should be paid to women aged 50 years or older, especially

To determine the type of glaucoma in subjects with diabetes mellitus detected during a diabetic retinopathy screening program and to determine any association between diabetic retinopathy (DR) and glaucoma. This is a population-based prospective cross-sectional study, in which subjects with diabetes mellitus underwent screening for DR in a primary care outpatient clinic. Digital fundus photographs were taken and graded for presence/absence and severity of DR. During this grading, those fundus photographs showing increased cup-to-disc ratio (CDR) (≥0.6) were identified and these patients were referred to the specialist ophthalmology clinic for detailed examination. The presence of glaucoma was established based on CDR and abnormal visual field (VF) defects according to Hodapp-Parrish-Anderson's criteria. An elevation of intraocular pressure was not required for the diagnosis of glaucoma. The patients said to have definite glaucoma were those with vertical CDR>/=0.6, glaucomatous defects on VF examination, or retinal nerve fiber thinning if VF was unreliable. Of the 2182 subjects who underwent screening, 81 subjects (3.7%) had increased CDR and 40 subjects (1.8%) had confirmed glaucoma. Normal-tension variant of primary open-angle glaucoma was the most prevalent type (1.2%) We did not find any evidence that DR is a risk factor for glaucoma [odds ratio for DR vs. no DR=1.22 (95% confidence interval, 0.59-2.51)]. The overall prevalence of glaucoma in this diabetic population, based on finding increased cupping of optic disc in a teleretinal screening program was 1.8% (95% confidence interval, 1.0-3.0).

Chinese women have been consistently reported as having low breast cancer screening practices. The Chinese Breast Cancer Screening Beliefs Questionnaire (CBCSB) was designed to assess Chinese Australian women's beliefs, knowledge, and attitudes toward breast cancer and screening practices. The objectives of the study were to confirm the factor structure of the CBCSB with a new, larger sample of immigrant Chinese Australian women and to report its clinical validity. A convenience sample of 785 Chinese Australian women was recruited from Chinese community organizations and shopping malls. Cronbach α was used to assess internal consistency reliability, and Amos v18 was used for confirmatory factor analysis. Clinical validity was assessed through linear regression using SPSS v18. The 3-factor structure of the CBCSB was confirmed, although the model required respecification to arrive at a suitable model fit as measured by the goodness-of-fit index (0.98), adjusted goodness-of-fit index (0.97), normed fit index (0.95), and root mean square error of approximation (0.031). Internal consistency reliability coefficients were satisfactory (>.6). Women who engaged in all 3 types of screening had more proactive attitudes to health checkups and perceived less barriers to mammographic screening. The CBCSB is a valid and reliable tool for assessing Chinese women's beliefs, knowledge, and attitudes about breast cancer and breast cancer screening practices. The CBCSB can be used for providing practicing nurses with insights into the provision of culturally sensitive breast health education.

For mental health outreach programs for older adults, accurately detecting depression is key to quality service provision. Multiple factors, including gender, cognitive impairment, or recent bereavement may affect depression detection, but this is under-studied. Therefore, we sought to both establish rates of depressive symptom detection and to examine factors associated with inaccuracies of detecting depression among participants in a mental health outreach program serving older adults. We conducted a chart review of 1126 cases in an older adult-focused mental health outreach program in New Hampshire, the Referral Education Assistance & Prevention (REAP) program. Accuracy of depression detection was identified by comparing screen-positive scores for depressive symptoms on the 15-item Geriatric Depression Scale (GDS) to depression identification by counselors on a 'presenting concerns' list. Inaccurate depression detection (positive on the GDS but depression not identified by counselors) occurred in 27.6% of cases. Multivariate regression analyses indicated that anxiety, cognitive concerns, and rurality were all associated with detection innaccuracy. This study appears to be the first to examine factors influencing depression detection in a mental health outreach program. Future efforts should help ensure that all older mental health outreach clients have depression detected at optimal rates.

To estimate the prevalence and referral rates in well born and high risk babies using two step hearing screening protocol with Distortion Product Otoacoustic Emissions (DPOAE) and Automated Auditory Brainstem Response (AABR). A prospective study was carried out on 1405 neonates (983 well born babies and 422 high risk babies) who were screened during May 2013 to January 2015 at Institute of Obstetrics and Gynecology, Madras Medical College, Chennai. All neonates were screened using two step screening protocol. They were initially tested with DPOAE. Referred babies in DPOAE were screened with AABR subsequently. Among 1405 (100%) neonates 983 (69.96%) were well born babies and 422 (30.03%) were high risk babies. Total referral rate in DPOAE was found to be 311 (22.13%) among which 195 (13.87%) were well born babies and 116 (8.25%) were high risk babies. Out of 311 babies 31 (2.20%) babies were referred in AABR screening. In 31 babies referred in AABR 11(0.78%) were from well born group and 20 (1.42%) were from the high risk group. Further diagnostic evaluation of these babies, 2 (0.14%) were confirmed to have hearing loss. This study reveals, the prevalence of congenital hearing loss in our population is 1.42 per 1000 babies. Using two step protocol especially AABR along with DPOAE at the initial level of testing significantly reduces referral rates in new born screening programs. Also AABR decreases the false positive responses hence increasing the efficiency of screening program. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To outline the design of a clinical trial to evaluate the impact of HPV vaccination as part of a hrHPV-based primary screening program to extend screening intervals. A total of 18,000 women aged 25-45 years, attending the regular cervical cancer-screening program in primary health care services in Tlalpan, Mexico City, will be invited to the study. Eligible participants will be assigned to one of three comparison groups: 1) HPV16/18 vaccine and hrHPV-based screening; 2) HPV6/11/16/18 vaccine and hrHPV-based screening; 3) Control group who will receive only hrHPV-based screening. Strict surveillance of hrHPV persistent infection and occurrence of precancerous lesions will be conducted to estimate safety profiles at different screening intervals; participants will undergo diagnosis confirmation and treatment as necessary. The FASTER-Tlalpan Study will provide insights into new approaches of cervical cancer prevention programs. It will offer valuable information on potential benefits of combining HPV vaccination and hrHPV-based screening to safety extend screening intervals.

The attendance rate in Estonian cervical cancer screening programme is too low therefore the programme is hardly effective. A cross-sectional population based survey was performed to identify awareness of cervical cancer risk factors, reasons why women do not want to participate in cervical screening programme and wishes for better organisation of the programme. An anonymous questionnaire with a covering letter and a prepaid envelope was sent together with the screening invitation to 2942 randomly selected women. Results are based on the analysis of 1054 (36%) returned questionnaires. Main reasons for non-participation in the national screening programme were a recent visit to a gynaecologist (42.3%), fear to give a Pap-smear (14.3%), long appointment queues (12.9%) and unsuitable reception hours (11.8%). Fear to give a Pap-smear was higher among women aged 30 and 35 than 50 and 55 (RR 1.46; 95% CI: 0.82-2.59) and women with one or no deliveries (RR 1.56, 95% CI: 0.94-2.58). In general, awareness of cervical cancer risk factors is poor and it does not depend on socio-demographic factors. Awareness of screening was higher among Estonians than Russians (RR 1.64, 95% CI: 1.46-1.86). Most women prefer to receive information about screening from personally mailed invitation letters (74.8%). Women need more information about cervical cancer risk factors and the screening programme. They prefer personally addressed information sharing. Minority groups should be addressed in their own language. A better collaboration with service providers and discouraging smears outside the programme are also required.

Aim To investigate urban-rural differences in the distribution of risk factors for breast cancer. Methods We analyzed the data from the first round of the “Mamma” population based-screening program conducted in Croatia between 2007 and 2009 and self-reported questionnaire results for 924 patients with histologically verified breast cancer. Reproductive and anthropometric characteristics, family history of breast cancer, history of breast disease, and prior breast screening history were compared between participants from the city of Zagreb (n = 270) and participants from 13 counties with more than 50% of rural inhabitants (n = 654). Results The screen-detected breast cancer rate was 4.5 per 1000 mammographies in rural counties and 4.6 in the city of Zagreb, while the participation rate was 61% in rural counties and 59% in Zagreb. Women from Zagreb had significantly more characteristics associated with an increased risk of breast cancer (P < 0.001 in all cases): no pregnancies (15% vs 7%), late age of first pregnancy (≥30 years) (10% vs 4%), and the most recent mammogram conducted 2-3 years ago (32% vs 14%). Women from rural counties were more often obese (41% vs 28%) and had early age of first live birth (<20 years) (20% vs 7%, P < 0.001 for both). Conclusion Identification of rural-urban differences in mammography use and their causes at the population level can be useful in designing and implementing interventions targeted at the reduction of inequalities and modifiable risk factors.

One of the economic evaluation techniques involves calculation of willingness to pay (WTP) for a service to find out the value of that service from the clients' perspective. This study estimated WTP for both breast cancer and osteoporosis screening and comparatively examined the contributing factors. In fact, the comparisons served to provide an exact analysis of individual attitudes and behaviors in relation to screening programs for cancers and other diseases. This study was first designed in six scenarios several questionnaires concerning individual breast cancer and osteoporosis screening cases, and determined the WTP median in each scenario between people in Kerman Province of Iran in 2016. Then, the demand function for breast cancer and osteoporosis screening was formulated. Moreover, the factors contributing to WTP were examined through various scenarios in Stata and econometric techniques. The median and mean values of WTP in all the above scenarios were greater for breast cancer screening than for osteoporosis screening. Theoretically, the price assumed a minus sign whereas risk assumed a plus sign within the demand function formulated for both screening programs. Regarding the evaluated factors, age in breast cancer screening and risk of disease in osteoporosis screening were the major factors contributing to WTP. Breast cancer screening was more valuable than osteoporosis screening program from the perspective of the subjects. The programs can be successfully designed by concentrating on patients' age groups in breast cancer screening and high-risk patients in osteoporosis screening.

Diabetic retinopathy is the first cause of blindness during working years. Provide knowledge of screening coverage, prevalence and level of diabetic retinopathy in patients that belong to the Cardiovascular Health Program in primary care. Analysis of retinographies performed to 9076 diabetic patients aged 61 ± 13 years (61% women) adscribed to a Cardiovascular Health program in primary care centers of South-East Metropolitan Santiago. The examination was carried out by the evaluation of retinographies by trained optometrists. The coverage of the screening program was 21%. The prevalence of sight threatening diabetic retinopathy was 3,1%. The prevalence of these entities was 45% higher in people aged between 18 and 44 years than in older people. Their prevalence in urban communities was 32% higher than in rural locations. The coverage of the screening program is low. Diabetic patients aged 18 to 44 years and those coming from urban communities have a higher prevalence of severe non-proliferative and proliferative diabetic retinopathy.

To determine the incremental cost-effectiveness of a new telemedicine technician-based assessment relative to an existing model of family physician (FP)-based assessment of diabetic retinopathy (DR) in Singapore from the health system and societal perspectives. Model-based, cost-effectiveness analysis of the Singapore Integrated Diabetic Retinopathy Program (SiDRP). A hypothetical cohort of patients aged 55 years with type 2 diabetes previously not screened for DR. The SiDRP is a new telemedicine-based DR screening program using trained technicians to assess retinal photographs. We compared the cost-effectiveness of SiDRP with the existing model in which FPs assess photographs. We developed a hybrid decision tree/Markov model to simulate the costs, effectiveness, and incremental cost-effectiveness ratio (ICER) of SiDRP relative to FP-based DR screening over a lifetime horizon. We estimated the costs from the health system and societal perspectives. Effectiveness was measured in terms of quality-adjusted life-years (QALYs). Result robustness was calculated using deterministic and probabilistic sensitivity analyses. The ICER. From the societal perspective that takes into account all costs and effects, the telemedicine-based DR screening model had significantly lower costs (total cost savings of S$173 per person) while generating similar QALYs compared with the physician-based model (i.e., 13.1 QALYs). From the health system perspective that includes only direct medical costs, the cost savings are S$144 per person. By extrapolating these data to approximately 170 000 patients with diabetes currently being screened yearly for DR in Singapore's primary care polyclinics, the present value of future cost savings associated with the telemedicine-based model is estimated to be S$29.4 million over a lifetime horizon. While generating similar health outcomes, the telemedicine-based DR screening using technicians in the primary care setting saves costs for Singapore compared

To explore the factors that contribute to children's screen-related sedentary (S-RS) behaviors. Elementary schools. A random sample of children in grades five and six and their parents. The outcome measure was children's S-RS activity level measured by a self-administered questionnaire. A full spectrum of potential contributing factors for children's S-RS behaviors was obtained through surveys. Multilevel linear regression methods were used to determine the associations between these factors and children's screen time (hours per day) and results were expressed as regression coefficients (g). Of 955 child-parent pairs in 14 participating schools, 508 pairs (53%) completed the surveys. At an intrapersonal level, protective factors included being a girl (g = -.71); belonging to a sports team inside (g = -.56) or outside (g = -.49) of school; having a negative attitude toward S-RS activities (g = -.13); and having a positive attitude toward physical activity (g = .48). At the interpersonal and social levels, parental leisure S-RS behaviors (g = .32) were positively associated, whereas strict parental rules on computer use (g = -.27) and family income (g = -.32) were inversely correlated with S-RS behavior. At the environmental level, the presence of TVs in children's bedrooms (g = .44) and owning videogame devices (g = .58) increased the risk of S-RS behaviors, whereas after school programs (g = - .86) and schools' participation in the Turn Off the Screen Week campaign (g = -.91) decreased the risk. Public health interventions should target multilevel factors, including increasing children's awareness, promoting parental involvement in healthy lifestyle pursuits, and creating less screenogenic environments.

Background: Noncommunicable disease (NCDs), psychological, substance use disorders, and stress-related issues have been less understood in Indian industrial settings. Systems for screening and early identification of the above have not been integrated in workplaces, nor there is a strong regulatory backing for the same. Aim: To explore the feasibility of integrating mental health and select NCD risk factor screening with the periodical medical examination of employees. To identify proportion of employees with select NCD risk factors and symptoms suggestive of mental health problems. Settings and Design: Around 10% of employees from a leading motor industry in Bangalore, (706) participated in this cross-sectional voluntary screening program. Materials and Methods: This screening was conducted as a part of their annual medical examination. A mixed method of self-report and interview administered technique was adopted for the same. Statistical Analysis: Descriptive statistical methods (proportions, median, mean, and standard deviation (SD)) and Chi-square test of significance. Results and Conclusions: Screening revealed the following; tobacco use (18%), alcohol use (57%), perceived work stress (10%), and obesity (3%). Nearly 23% screened positive for psychological distress. Time consumed for this assessment was 1–5 min. Initial attempts point out that it is feasible to integrate screening for mental health, substance use, and NCD risk factors in periodic medical examination using a combination of self-report and interview-administered method, though further detailed assessments for confirmation is necessary.

Incidences of UV-induced skin cancer are continuously increasing. For this reason, early diagnosis is becoming more important. In this study, 783 employees of a technical company participated in an employee skin cancer screening program, which consisted of a physical examination for benign and malignant skin lesions and premalignant conditions. To ensure the quality of the examinations, screening was only performed by 5 trained dermatologists. Participants also were asked to complete a standardized questionnaire prior to examination. A total of 661 skin lesions were diagnosed among 48% of participants; 12.8% of participants exhibited 50 or more melanocytic nevi and the risk for developing skin cancer was categorized as at least moderate for 64.9%. Additionally, 84.4% of participants with at least 1 skin lesion were advised to have a checkup within 1 year. The high rate of suspicious nevi detected in this study suggested that employee skin cancer screening programs are effective and also should be recommended at companies where employees are not at increased risk for developing skin cancer due to the nature of their work (eg, those who work outdoors). Despite the comparatively selective and young study population, these examinations provide evidence of the importance of skin cancer screening for the wider population.

Patients with asymptomatic left ventricular systolic dysfunction (ALVSD) have an increased risk of heart failure (HF) and a worse life expectancy. Since valuable therapies may prevent such dismal evolution, screening programs for ALVSD have recently been advocated to detect as early as possible such ominous condition. Echocardiography represents the gold standard for the assessment of ALVSD but its indiscriminate use in screening programs is impractical. Clinical multivariate risk assessment associated with ECG and serum brain natriuretic peptide (BNP) may be a feasible strategy to screen ALVSD. We prospectively sought to investigate the feasibility and effectiveness of a screening program for ALVSD based on ECG and BNP used in a hierarchical sequence in patients at high risk for HF. Patients > or =55 years old with > or =2 risk factors for HF or > or =70 years old with > or =1 risk factor for HF entered the study performing sequentially ECG, BNP and echocardiographic evaluation. ALVSD was defined as a left ventricular ejection fraction < or =50%. Thirty-three of 122 enrolled patients (27%) had ALVSD. They were older, presented more frequently a history of chemotherapy exposure, had often bundle branch block and higher BNP levels. No patient without any major abnormalities (atrial fibrillation, left ventricular hypertrophy, STT alterations of ischemic/strain origin, pathologic Q wave, bundle branch block) on ECG (n=31, 24.4%) had ALVSD. Among the 91 patients with abnormal ECG, ALVSD was observed in 33 (36%). The area under the receiver operating characteristic curve to detect ALVSD by BNP was 0.86 (confidence interval 0.79-0.94, p<0.0001) and BNP values of > or =43 pg/ml showed a sensitivity and a specificity of 94% and 57%, respectively. The proposed screening program was able to identify 95% (31/33) of patients with ALVSD saving 53% of echocardiographic examinations with a substantial reduction of the costs to diagnose ALVSD.

A comparative examination of tuberculosis immigration medical screening programs from selected countries with high immigration and low tuberculosis incidence rates

PubMed Central

2011-01-01

Background Tuberculosis (TB) in migrants is an ongoing challenge in several low TB incidence countries since a large proportion of TB in these countries occurs in migrants from high incidence countries. To meet these challenges, several countries utilize TB screening programs. The programs attempt to identify and treat those with active and/or infectious stages of the disease. In addition, screening is used to identify and manage those with latent or inactive disease after arrival. Between nations, considerable variation exists in the methods used in migration-associated TB screening. The present study aimed to compare the TB immigration medical examination requirements in selected countries of high immigration and low TB incidence rates. Methods Descriptive study of immigration TB screening programs Results 16 out of 18 eligible countries responded to the written standardized survey and phone interview. Comparisons in specific areas of TB immigration screening programs included authorities responsible for TB screening, the primary objectives of the TB screening program, the yield of detection of active TB disease, screening details and aspects of follow up for inactive pulmonary TB. No two countries had the same approach to TB screening among migrants. Important differences, common practices, common problems, evidence or lack of evidence for program specifics were noted. Conclusions In spite of common goals, there is great diversity in the processes and practices designed to mitigate the impact of migration-associated TB among nations that screen migrants for the disease. The long-term goal in decreasing migration-related introduction of TB from high to low incidence countries remains diminishing the prevalence of the disease in those high incidence locations. In the meantime, existing or planned migration screening programs for TB can be made more efficient and evidenced based. Cooperation among countries doing research in the areas outlined in this study should

Objective. To analyze interval cancers among participants in a screening program for colorectal cancer (CRC) during four screening rounds. Methods. The study population consisted of participants of a fecal occult blood test-based screening program from February 2000 to September 2010, with a 30-month follow-up (n = 30,480). We used hospital administration data to identify CRC. An interval cancer was defined as an invasive cancer diagnosed within 30 months of a negative screening result and before the next recommended examination. Gender, age, stage, and site distribution of interval cancers were compared with those in the screen-detected group. Results. Within the study period, 97 tumors were screen-detected and 74 tumors were diagnosed after a negative screening. In addition, 17 CRC (18.3%) were found after an inconclusive result and 2 cases were diagnosed within the surveillance interval (2.1%). There was an increase of interval cancers over the four rounds (from 32.4% to 46.0%). When compared with screen-detected cancers, interval cancers were found predominantly in the rectum (OR: 3.66; 95% CI: 1.51-8.88) and at more advanced stages (P = 0.025). Conclusion. There are large numbers of cancer that are not detected through fecal occult blood test-based screening. The low sensitivity should be emphasized to ensure that individuals with symptoms are not falsely reassured.

Peru struggles to prevent cervical cancer (CC). In the jungle, prevention programs suffer from significant barriers although technology exists to detect CC precursors. This study used community based participatory research (CBPR) methods to overcome barriers. The objective was to evaluate the utility of CBPR techniques in a mother–child screen/treat and vaccinate program for CC prevention in the Peruvian jungle. The CC prevention program used self-sampling for human papillomavirus (HPV) for screening, cryotherapy for treatment and the HPV vaccine Gardasil for vaccination. Community health leaders (HL) from around Iquitos participated in a two half day educational course. The HLs then decided how to implement interventions in their villages or urban sectors. The success of the program was measured by: (1) ability of the HLs to determine an implementation plan, (2) proper use of research forms, (3) participation and retention rates, and (4) participants’ satisfaction. HLs successfully registered 320 women at soup kitchens, schools, and health posts. Screening, treatment, and vaccination were successfully carried out using forms for registration, consent, and results with minimum error. In the screen/treat intervention 100 % of participants gave an HPV sample and 99.7 % reported high satisfaction; 81 % of HPV + women were treated, and 57 % returned for 6-month followup.

Peru struggles to prevent cervical cancer (CC). In the jungle, prevention programs suffer from significant barriers although technology exists to detect CC precursors. This study used community based participatory research (CBPR) methods to overcome barriers. The objective was to evaluate the utility of CBPR techniques in a mother-child screen/treat and vaccinate program for CC prevention in the Peruvian jungle. The CC prevention program used self-sampling for human papillomavirus (HPV) for screening, cryotherapy for treatment and the HPV vaccine Gardasil for vaccination. Community health leaders (HL) from around Iquitos participated in a two half day educational course. The HLs then decided how to implement interventions in their villages or urban sectors. The success of the program was measured by: (1) ability of the HLs to determine an implementation plan, (2) proper use of research forms, (3) participation and retention rates, and (4) participants' satisfaction. HLs successfully registered 320 women at soup kitchens, schools, and health posts. Screening, treatment, and vaccination were successfully carried out using forms for registration, consent, and results with minimum error. In the screen/treat intervention 100% of participants gave an HPV sample and 99.7% reported high satisfaction; 81% of HPV + women were treated, and 57% returned for 6-month followup. Vaccine intervention: 98% of girls received the 1st vaccine, 88% of those received the 2nd, and 65% the 3rd. CBPR techniques successfully helped implement a screen/treat and vaccinate CC prevention program around Iquitos, Peru. These techniques may be appropriate for large-scale preventive health-care interventions.

The DuPage Patient Navigation Collaborative evaluated the Patient Navigation Research Program (PNRP) model for uninsured women receiving free breast or cervical cancer screening through the Illinois Breast and Cervical Cancer Program in DuPage County, Illinois. We used medical records review and patient surveys of 477 women to compare median follow-up times with external Illinois Breast and Cervical Cancer Program and Chicago PNRP benchmarks of performance. We examined the extent to which we mitigated community-defined timeliness risk factors for delayed follow-up, with a focus on Spanish-speaking participants. Median follow-up time (29.0 days for breast and 56.5 days for cervical screening abnormalities) compared favorably to external benchmarks. Spanish-speaking patients had lower health literacy, lower patient activation, and more health care system distrust than did English-speaking patients, but despite the prevalence of timeliness risk factors, we observed no differences in likelihood of delayed (> 60 days) follow-up by language. Our successful replication and scaling of the PNRP navigation model to DuPage County illustrates a promising approach for future navigator research.

Screening Program Reduced Melanoma Mortality at the Lawrence Livermore National Laboratory, 1984-1996

Schneider, MD, J S; II, PhD, D; MD, PhD, M

Worldwide incidence of cutaneous malignant melanoma has increased substantially, and no screening program has yet demonstrated reduction in mortality. We evaluated the education, self examination and targeted screening campaign at the Lawrence Livermore National Laboratory (LLNL) from its beginning in July 1984 through 1996. The thickness and crude incidence of melanoma from the years before the campaign were compared to those obtained during the 13 years of screening. Melanoma mortality during the 13-year period was based on a National Death Index search. Expected yearly deaths from melanoma among LLNL employees were calculated by using California mortality data matched by age,more » sex, and race/ethnicity and adjusted to exclude deaths from melanoma diagnosed before the program began or before employment at LLNL. After the program began, crude incidence of melanoma thicker than 0.75 mm decreased from 18 to 4 cases per 100,000 person-years (p = 0.02), while melanoma less than 0.75mm remained stable and in situ melanoma increased substantially. No eligible melanoma deaths occurred among LLNL employees during the screening period compared with a calculated 3.39 expected deaths (p = 0.034). Education, self examination and selective screening for melanoma at LLNL significantly decreased incidence of melanoma thicker than 0.75 mm and reduced the melanoma-related mortality rate to zero. This significant decrease in mortality rate persisted for at least 3 yr after employees retired or otherwise left the laboratory.« less

The current study aims to examine the effects of human resource (measured with the perception of health workers' perception towards UNHS), screening equipment, program layout and screening techniques on healthcare practitioners' awareness (measured with knowledge) of universal newborn hearing screening (UNHS) in Malaysian non-public hospitals. Via cross sectional approach, the current study collected data using a validated questionnaire to obtain information on the awareness of UNHS program among the health practitioners and to test the formulated hypotheses. 51, representing 81% response rate, out of 63 questionnaires distributed to the health professionals were returned and usable for statistical analysis. The survey instruments involving healthcare practitioners' awareness, human resource, program layout, screening instrument, and screening techniques instruments were adapted and scaled with 7-point Likert scale ranging from 1 (little) to 7 (many). Partial Least Squares (PLS) algorithm and bootstrapping techniques were employed to test the hypotheses of the study. With the result involving beta values, t-values and p-values (i.e. β=0.478, t=1.904, p<0.10; β=0.809, t=3.921, p<0.01; β= -0.436, t=1.870, p<0.10), human resource, measured with training, functional equipment and program layout, are held to be significant predictors of enhanced knowledge of health practitioners. Likewise, program layout, human resource, screening technique and screening instrument explain 71% variance in health practitioners' awareness. Health practitioners' awareness is explained by program layout, human resource, and screening instrument with effect size (f2) of 0.065, 0.621, and 0.211 respectively, indicating that program layout, human resource, and screening instrument have small, large and medium effect size on health practitioners' awareness respectively. However, screening technique has zero effect on health practitioners' awareness, indicating the reason why T-statistics is

This study examined the use of breast cancer screening education programs in 102 of the major workplaces in Forsyth County, North Carolina. Characteristics of workplaces that had sponsored such programs within the preceding three years were identified. Eighteen percent of the workplaces surveyed had offered breast cancer screening education programs. Factors that were directly related to having sponsored a program included the size of the workforce, the number of female employees, and the proportion of female employees over 40 years old. Characteristics related to health service activities in the workplace were also predictive. Neither the type of industry nor the insurance status of the workplace was significantly related to having sponsored a program.

Wehner, Nora; Weiste, Christoph; Dröge-Laser, Wolfgang

2011-01-01

In the model plant Arabidopsis thaliana, more than 2000 genes are estimated to encode transcription factors (TFs), which clearly emphasizes the importance of transcriptional control. Although genomic approaches have generated large TF open reading frame (ORF) collections, only a limited number of these genes is functionally characterized, yet. This review evaluates strategies and methods to identify TF functions. In particular, we focus on two recently developed TF screening platforms, which make use of publically available GATEWAY®-compatible ORF collections. (1) The Arabidopsis thaliana TF ORF over-Expression (AtTORF-Ex) library provides pooled collections of transgenic lines over-expressing HA-tagged TF genes, which are suited for screening approaches to define TF functions in stress defense and development. (2) A high-throughput microtiter plate based protoplast trans activation (PTA) system has been established to screen for TFs which are regulating a given promoter:Luciferase construct in planta.

An alternative approach to intervention-control designs to evaluate community health education studies is to use a quasi-experimental design in which the outcomes of interest are examined over time in the intervention unit. The Forsyth County Cancer Screening Project (FoCaS) was a comprehensive clinic- and community-based education program to increase screening for cervical cancer and breast cancer among low-income women. This paper reports the use of piecewise regression accounting for potential effects of auto-correlation in the data to evaluate the effectiveness of the project in increasing mammography screening. Data for the evaluation of trends in screening consisted of all mammograms performed during the period of May 1992 through June 1995 at the Reynolds Health Center in Forsyth County, North Carolina. The results suggested that the FoCaS project was effective in increasing mammography screening among women age 40 or older in the study population. Analysis of the trends by age indicated that the program had differential effects on women age 40-49 and 50 or older. The results demonstrate that analyses of the type presented here can either complement or serve as an alternative to more traditional intervention-control analyses.

Diagnosis of retinal detachments by a tele-ophthalmology screening program.

In 2015, a tele-ophthalmology program was undertaken at the Atlanta Veterans Affairs Medical Center to provide screening eye care for veterans in their primary care clinics. Though this program was developed as a screening tool, the availability of these services in primary care clinics has enabled triage of certain acute eye complaints. These case reports describe two patients who were diagnosed with retinal detachments through this program, although their primary care providers had triaged them as requiring non-urgent referrals to the eye clinic. Although many patients are seen for acute ocular complaints in primary care clinics and emergency departments, providers in such settings may lack the ability to adequately examine eyes and thus triage ocular complaints. These cases demonstrate the ability of tele-ophthalmology to assist in diagnosing urgent ocular conditions in primary care clinics. Though tele-ophthalmology has been accepted in some parts of the world, in the United States of America it remains widely underutilized. These cases highlight the ability of tele-ophthalmology to close the gap in acute eye care coverage that exists in the USA, most prominently in rural regions.

Diabetes mellitus (DM) increases the risk of developing pulmonary tuberculosis (TB) disease. Therefore, pulmonary TB screening among DM patients is essential. This study aimed to identify factors associated with participation of DM type II patients in pulmonary TB screening using chest X-ray. This was a cross-sectional analytic study and was part of TB-DM screening study in Denpasar, Bali, Indonesia. The sample consisted of 365 DM type II patients selected by quota sampling among DM type II patients joining the screening program from January until March 2016 in 11 public health centres in Denpasar. Data were collected via structured interviews. The contributing factors were determined by modified Poisson regression test for cross-sectional data. From the findings, less than half (45.48%) of DM type II patients participated in chest X-ray examination for TB. Factors associated with participation in pulmonary TB screening were having a higher educational level [APR = 1.34, 95% CI (1.07-1.67)], having family member who developed pulmonary TB disease [APR = 1.47, 95% CI (1.12-1.93)], the travel time to referral hospital for screening being ≤ 15 minutes [APR = 1.6, 95% CI (1.26-2.03)], having health insurance [APR = 2.69, 95% CI (1.10-6.56)], and receiving good support from health provider [APR = 1.35, 95% CI (1.06-1.70)]. Therefore, training for health provider on providing counselling, involvement of family members in screening process, and improving the health insurance coverage and referral system are worth considering.

Problem alcohol use is associated with adverse health and economic outcomes, especially among people in opioid agonist treatment. Screening, brief intervention, and referral to treatment (SBIRT) are effective in reducing alcohol use; however, issues involved in SBIRT implementation among opioid agonist patients are unknown. To assess identification and treatment of alcohol use disorders, we reviewed clinical records of opioid agonist patients screened for an alcohol use disorder in a primary care clinic (n = 208) and in an opioid treatment program (n = 204) over a two-year period. In the primary care clinic, 193 (93%) buprenorphine patients completed an annual alcohol screening and six (3%) had elevated AUDIT scores. In the opioid treatment program, an alcohol abuse or dependence diagnosis was recorded for 54 (27%) methadone patients. Practitioner focus groups were completed in the primary care (n = 4 physicians) and the opioid treatment program (n = 11 counselors) to assess experience with and attitudes towards screening opioid agonist patients for alcohol use disorders. Focus groups suggested that organizational, structural, provider, patient, and community variables hindered or fostered alcohol screening. Alcohol screening is feasible among opioid agonist patients. Effective implementation, however, requires physician training and systematic changes in workflow.

The current use and content of screening tools utilized by ASHP-accredited pharmacy residency programs were assessed. A survey consisting of 19 questions assessing residency programs and the screening of pharmacy residency program applicants was e-mailed to residency directors of 362 pharmacy residency programs at 105 University HealthSystem Consortium (UHC)-member institutions. Questions gathered general program demographic information, data related to applicant growth from residency years 2010-11 to 2011-12, and information about the residency screening processes currently used. Responses were received from 73 residency program sites (69.5%) of the 105 UHC-member institutions to whom the e-mail was sent. Many sites used screening tools to calculate applicants' scores and then determined which candidates to invite for an onsite interview based on applicants' scores and group discussion. Seventy-eight percent (n = 57) of the 73 responding institutions reported the use of a screening tool or rubric to select applicants to invite for onsite interviews. The most common method of evaluation was individual applicant review before meeting as a group to discuss candidate selection. The most important factor for determining which residency candidate to interview was the overall impression based on the candidate's curriculum vitae (CV) and letters of recommendation. Most residency programs in UHC-member hospitals used a screening tool to determine which applicants to invite for an onsite interview. The most important factor for determining which residency candidate to interview was the overall impression based on the candidate's CV and letters of recommendation.

Objective: From the perspective of actual service suppliers regarding cancer screening, this study aimed to assess the long-term sustainability of cancer screening programs in China. Methods: Based on a Cancer Screening Program in Urban China (CanSPUC), our survey focused on all the hospitals, centers for disease control and prevention (CDC) and community service centers across 16 provinces in China which participated in the programs between 2013 and 2015. All the managers (institutional/department level) and professional staff involved in the program were interviewed using either paper-based questionnaire or online approach. Results: A total of 4 626 participants completed the interview. It showed that the main gains from providing screening service emphasized promotion in social value (63.6%), local reputation (35.9%), and professional skills (30.6%), whereas difficulties encountered included inadequate compensation (30.9%) and discordance among information systems (28.3%). When the service remuneration amounts to about 50 Chinese Yuan per screening item, those professional staff self-reported that they would like to work overtime. More than half (63.7%) of the staff expressed willingness to provide routine screening service, the main expectations were to promote their reputation to the local residents (48.7%) and to promote professional skills (43.1%). Those who were not willing to provide screening services were worried about the potential heavy workload (59.8%) or being interfered with their routine work (49.8%). Further detailed results regarding the different organization types and program roles were presented in the following detailed report. Conclusions: Findings of gains and difficulties showed that if cancer screening is expected to become a long-term running, incentive mechanism from the program, external promotion and advocacy as well as capacity building should be strengthened; furthermore, rewards to staff's screening services should be raised

Screening synteny blocks in pairwise genome comparisons through integer programming.

It is difficult to accurately interpret chromosomal correspondences such as true orthology and paralogy due to significant divergence of genomes from a common ancestor. Analyses are particularly problematic among lineages that have repeatedly experienced whole genome duplication (WGD) events. To compare multiple "subgenomes" derived from genome duplications, we need to relax the traditional requirements of "one-to-one" syntenic matchings of genomic regions in order to reflect "one-to-many" or more generally "many-to-many" matchings. However this relaxation may result in the identification of synteny blocks that are derived from ancient shared WGDs that are not of interest. For many downstream analyses, we need to eliminate weak, low scoring alignments from pairwise genome comparisons. Our goal is to objectively select subset of synteny blocks whose total scores are maximized while respecting the duplication history of the genomes in comparison. We call this "quota-based" screening of synteny blocks in order to appropriately fill a quota of syntenic relationships within one genome or between two genomes having WGD events. We have formulated the synteny block screening as an optimization problem known as "Binary Integer Programming" (BIP), which is solved using existing linear programming solvers. The computer program QUOTA-ALIGN performs this task by creating a clear objective function that maximizes the compatible set of synteny blocks under given constraints on overlaps and depths (corresponding to the duplication history in respective genomes). Such a procedure is useful for any pairwise synteny alignments, but is most useful in lineages affected by multiple WGDs, like plants or fish lineages. For example, there should be a 1:2 ploidy relationship between genome A and B if genome B had an independent WGD subsequent to the divergence of the two genomes. We show through simulations and real examples using plant genomes in the rosid superorder that the quota

Population-based screening programs have resulted in minimizing mortality and morbidity from cervical cancer. The aim of this integrative review was to explore the factors influencing access of women from Western Asian and Middle Eastern Arab countries to cervical cancer screening. A systematic search for studies conducted in Arab countries in those regions, and published in English between January 2002 and January 2017, was undertaken. Thirteen papers were selected and subjected to quality appraisal. A three step analysis was used, which involved a summary of the evidence, analysis of both quantitative and qualitative data, and integration of the results in narrative form. Few population-based cervical cancer screening programs had been implemented in the relevant countries, with low knowledge of, and perceptions about, cervical screening among Arab women, the majority of whom are Muslim. Factors affecting the uptake of cervical cancer screening practices were the absence of organized, systematic programs, low screening knowledge among women, healthcare professionals' attitudes toward screening, pain and embarrassment, stigma, and sociocultural beliefs. Policy changes are urgently needed to promote population-based screening programs. Future research should address the promotion of culturally-sensitive strategies to enable better access of Arab Muslim women to cervical cancer screening. © 2017 John Wiley & Sons Australia, Ltd.

Background Screening for serum cryptococcal antigen (CrAg) may identify those at risk for disseminated cryptococcal disease (DCD), and pre-emptive fluconazole treatment may prevent progression to DCD. In August 2012, the Western Cape Province (WC), South Africa, adopted provider-initiated CrAg screening. We evaluated the implementation and effectiveness of this large-scale public-sector program during its first year, September 1, 2012—August 31, 2013. Methods We used data from the South African National Health Laboratory Service, WC provincial HIV program, and nationwide surveillance data for DCD. We assessed the proportion of eligible patients screened for CrAg (CrAg test done within 30 days of CD4 date) and the prevalence of CrAg positivity. Incidence of DCD among those screened was compared with those not screened. Results Of 4,395 eligible patients, 26.6% (n=1170) were screened. The proportion of patients screened increased from 15.9% in September 2012 to 36.6% in August 2013. The prevalence of positive serum CrAg was 2.1%. Treatment data were available for 13 of 24 CrAg-positive patients; nine of 13 were treated with fluconazole. Nine (0.8%) incident cases of DCD occurred among the 1170 patients who were screened for CrAg vs. 49 (1.5%) incident cases among the 3225 patients not screened (p=0.07). Conclusions Relatively few eligible patients were screened under the WC provider-initiated CrAg screening program. Unscreened patients were nearly twice as likely to develop DCD. CrAg screening can reduce the burden of DCD, but needs to be implemented well. To improve screening rates, countries should consider laboratory-based reflexive screening when possible. PMID:26926942

We analyzed hemochromatosis detection in a 11.5-year multiphasic health screening program at a forest products mill. There were 2199 participants: 2032 Whites (1506 men, 526 women) and 167 African Americans (124 men, 43 women); 85.0% of employees were screened. Iron and transferrin saturation were measured in a serum biochemistry profile on specimens obtained after overnight fasting; ferritin was measured in participants with elevated iron concentrations or transferrin saturation > 48%. Participants with elevated ferritin levels underwent further evaluation. Eight White men were diagnosed to have hemochromatosis (frequency 0.0039 in Whites, 0.0053 in White men). The estimated cost per case detected was $8826. Family members of two participants with hemochromatosis were also diagnosed to have hemochromatosis or iron overload. We conclude that detecting hemochromatosis in a workplace multiphasic health screening program is efficacious and economical.

There are conflicting views as to whether testing for biotinidase deficiency (BD) ought to be incorporated into universal newborn screening (NBS) programs. The aim of this study was to evaluate the cost-effectiveness of adding BD to the panel of conditions currently screened under the national NBS program in Spain. We used information from the regional NBS program for BD that has been in place in the Spanish region of Galicia since 1987. These data, along with other sources, were used to develop a cost-effectiveness decision model that compared lifetime costs and health outcomes of a national birth cohort of newborns with and without an early detection program. The analysis took the perspective of the Spanish National Health Service. Effectiveness was measured in terms of quality-adjusted life years (QALYs). We undertook extensive sensitivity analyses around the main model assumptions, including a probabilistic sensitivity analysis. In the base case analysis, NBS for BD led to higher QALYs and higher health care costs, with an estimated incremental cost per QALY gained of $24,677. Lower costs per QALY gained were found when conservative assumptions were relaxed, yielding cost savings in some scenarios. The probability that BD screening was cost-effective was estimated to be >70% in the base case at a standard threshold value. This study indicates that NBS for BD is likely to be a cost-effective use of resources. Copyright © 2015 by the American Academy of Pediatrics.

Identifying, screening and engaging high-risk clients in private non-profit child abuse prevention programs.

1986-01-01

Child abuse prevention programs rely on varied strategies to identify, screen, obtain referrals of, and engage high risk parents. Available literature on community-based child abuse prevention projects is not conclusive about project outcomes nor sufficiently descriptive about implementation. From the literature, experience and interviews with staff from more than 20 programs, barriers to implementation are identifiable. Barriers arise during identifying and screening at-risk families, referral, continued collaboration with referrers, and engaging clients in services. The paper describes a diverse set of strategies for surmounting these barriers. Staff characteristics and concrete services partially predict the success of program implementation. So does the program's relationship to other agencies. Child abuse prevention programs assume independent, interdependent, and dependent relationships with other agencies and referrers. Interdependent programs appear to have the best chance of obtaining referrals and maintaining clients who match their program's intent.

The Cost of Screening and Brief Intervention in Employee Assistance Programs

Cowell, Alexander J.; Bray, Jeremy W.; Hinde, Jesse M.

2016-01-01

Few studies examine the costs of conducting screening and brief intervention (SBI) in settings outside health care. This study addresses this gap in knowledge by examining the employer-incurred costs of SBI in an employee assistance program (EAP) when delivered by counselors. Screening was self-administered as part of the intake paperwork, and the brief intervention (BI) was delivered during a regular counseling session. Training costs were $76 per counselor. The cost of a screen to the employer was $0.64; most of this cost comprised the cost of the time the client spent completing the screen. The cost of a BI was $1.86. The cost of SBI is lower than cost estimates of SBI conducted in a health care setting. The low costs for the current study suggest that only modest gains in outcomes would likely be needed to justify delivering SBI in an EAP setting. PMID:21938602

Screening was self-administered as part of the intake paperwork, and the brief intervention (BI) was delivered during a regular counseling session. Training costs were $83 per counselor. The cost of a screen to the employer was $0.64; most of this cost comprised the cost of the time the client spent completing the screen. The cost of a BI was $2.52. The cost of SBI is lower than cost estimates of SBI conducted in a health care setting. The low costs for the current study suggest that only modest gains in outcomes would likely be needed to justify delivering SBI in an EAP setting.

Background The aim of this study was to identify factors associated with cancer screening practices and with general attitudes toward cancer screening in a general population. Methods Mailed survey of 30–60 year old residents of Geneva, Switzerland, that included questions about screening for five cancers (breast, cervix uteri, prostate, colon, skin) in the past 3 years, attitudes toward screening, health care use, preventive behaviours and socio-demographic characteristics. Cancer screening practice was dichotomised as having done at least one screening test in the past 3 years versus none. Results The survey response rate was 49.3% (2301/4670). More women than men had had at least one cancer screening test in the past 3 years (83.2% vs 34.5%, p < 0.001). A majority of women had had a cervical smear (76.6%) and a mammography (age 30–49: 35.0%; age 50 and older: 90.3%); and 55.1% of men 50–60 years old had been screened for prostate cancer. Other factors associated with screening included older age, higher income, a doctor visit in the past 6 months, reporting a greater number of preventive behaviours and a positive attitude toward screening. Factors linked with positive attitudes included female gender, higher level of education, gainful employment, higher income, a doctor visit in the past 6 months and a personal history of cancer. Conclusion Attitudes play an important role in cancer screening practices among middle-aged adults in the general population, independent of demographic variables (age and sex) that determine in part screening recommendations. Negative attitudes were the most frequent among men and the most socio-economically disadvantaged. The moderate participation rate raises the possibility of selection bias. PMID:19402895

To evaluate ROP screening rates in a population-based cohort; and to identify characteristics of patients that were missed. We used the California Perinatal Quality Care Collaborative data from 2005-2007 for a cross-sectional study. Using eligibility criteria, screening rates were calculated for each hospital. Multivariable regression was used to assess associations between patient clinical and sociodemographic factors and the odds of missing screening. Overall rates of missed ROP screening decreased from 18.6% in 2005 to 12.8% in 2007. Higher gestational age (OR = 1.25 for increase of 1 week, 95% CI, 1.21-1.29), higher birth weight (OR = 1.13; 95% CI, 1.10-1.15), and singleton birth (OR = 1.2; 95% CI, 1.07-1.34) were associated with higher probability of missing screening. Level II neonatal intensive care units and neonatal intensive care units with lower volume were more likely to miss screenings. Although ROP screening rates improved over time, larger and older infants are at risk for not receiving screening. Furthermore, large variations in screening rates exist among hospitals in California. Identification of gaps in quality of care creates an opportunity to improve ROP screening rates and prevent impaired vision in this vulnerable population. Copyright © 2012 Mosby, Inc.

Sicsic, Jonathan; Franc, Carine

2017-06-01

A voluntary-based pay-for-performance (P4P) program (the CAPI) aimed at general practitioners (GPs) was implemented in France in 2009. The program targeted prevention practices, including breast cancer screening, by offering a maximal amount of €245 for achieving a target screening rate among eligible women enrolled with the GP. Our objective was to evaluate the impact of the French P4P program (CAPI) on the early detection of breast cancer among women between 50 and 74 years old. Based on an administrative database of 50,752 women aged 50-74 years followed between 2007 and 2011, we estimated a difference-in-difference model of breast cancer screening uptake as a function of visit to a CAPI signatory referral GP, while controlling for both supply-side and demand-side determinants (e.g., sociodemographics, health and healthcare use). Breast cancer screening rates have not changed significantly since the P4P program implementation. Overall, visiting a CAPI signatory referral GP at least once in the pre-CAPI period increased the probability of undergoing breast cancer screening by 1.38 % [95 % CI (0.41-2.35 %)], but the effect was not significantly different following the implementation of the contract. The French P4P program had a nonsignificant impact on breast cancer screening uptake. This result may reflect the fact that the low-powered incentives implemented in France through the CAPI might not provide sufficient leverage to generate better practices, thus inviting regulators to seek additional tools beyond P4P in the field of prevention and screening.

Background Community pharmacists' role in screening of several chronic diseases has been widely explored. The global health burden of chronic kidney disease is high; however, the progression and adverse outcomes can be prevented or delayed by detecting and treating the disease in its initial stages 1-3. Therefore, a web-based training program was developed to enhance pharmacists' knowledge and skills required to perform a chronic kidney disease screening service in a community setting. Objective The aim of this study was to evaluate the impact of a web-based training program on community pharmacists' knowledge and skills associated with chronic kidney disease screening. As secondary aim, pharmacists' satisfaction with the training program was assessed. Setting Community pharmacy practice. Method A web-based training program was developed by four pharmacists and a nephrologist. Quantitative data was collected by employing a self-administered, web-based questionnaire, which comprised a set of five multiple-choice knowledge questions and one clinical vignette to assess skills. A nine-item Likert scale was used to determine pharmacists' satisfaction with the training program. Main outcome measure Pharmacists' knowledge and skills scores at pre and post-training, reliability of the Likert scale, and the proportion of responses to the individual nine items of the satisfaction survey. Results Fifty pharmacists participated in the pre-questionnaire and 38 pharmacists completed the web-based training and post-questionnaire. Significant differences were observed in the knowledge scores (p < 0.001) and skills scores (p < 0.001) at pre- and post-training. Cronbach's alpha for the nine-item satisfaction scale was 0.73 and the majority pharmacists (92.1-100 %) were satisfied with the various aspects of the training program. Conclusion The web-based training program positively enhanced pharmacists' knowledge and skills associated with chronic kidney disease screening. These

To examine the conditions under which Screening, Brief Intervention and Referral to Treatment (SBIRT) programs can be sustained by health insurance payments. A mathematical model was used to estimate the number of patients needed for revenues to exceed costs. Three medical settings in the United States were examined: in-patient, out-patient and emergency department. Components of SBIRT were delivered by combinations of health-care practitioners (generalists) and behavioral health specialists. Practitioners in seven SBIRT programs who received grants from the US Substance Abuse and Mental Health Services Administration (SAMHSA). Program costs and revenues were measured using data from grantees. Patient flows were measured from administrative data and adjusted with prevalence and screening estimates from the literature. SBIRT can be sustained through health insurance reimbursement in out-patient and emergency department settings in most staffing mixes. To sustain SBIRT in in-patient programs, a patient flow larger than the national average may be needed; if that flow is achieved, the range of screens required to maintain a surplus is narrow. Sensitivity analyses suggest that the results are very sensitive to changes in the proportion of insured patients. Screening, Brief Intervention and Referral to Treatment programs in the United States can be sustained by health insurance payments under a variety of staffing models. Screening, Brief Intervention and Referral to Treatment programs can be sustained only in an in-patient setting with above-average patient flow (more than 2500 screens). Screening, Brief Intervention and Referral to Treatment programs in out-patient and emergency department settings can be sustained with below-average patient flows (fewer than 125 000 out-patient visits and fewer than 27 000 emergency department visits). © 2017 Society for the Study of Addiction.

Detection of critical congenital heart defects: Review of contributions from prenatal and newborn screening

2015-01-01

In 2011, statewide newborn screening programs for critical congenital heart defects began in the United States, and subsequently screening has been implemented widely. In this review, we focus on data reports and collection efforts related to both prenatal diagnosis and newborn screening. Defect-specific, maternal, and geographic factors are associated with variations in prenatal detection, so newborn screening provides a population-wide safety net for early diagnosis. A new web-based repository is collecting information on newborn screening program policies, quality indicators related to screening programs, and specific case-level data on infants with these defects. Birth defects surveillance programs also collect data about critical congenital heart defects, particularly related to diagnostic timing, mortality, and services. Individuals from state programs, federal agencies, and national organizations will be interested in these data to further refine algorithms for screening in normal newborn nurseries, neonatal intensive care settings, and other special populations; and ultimately to evaluate the impact of screening on outcomes.

Purpose To examine the outcomes of a breast cancer screening program based on digital breast tomosynthesis (DBT) plus synthesized two-dimensional (2D) mammography compared with those after full-field digital mammography (FFDM). Materials and Methods This prospective study included 16 666 asymptomatic women aged 50-69 years who were recruited in April 2015 through March 2016 for DBT plus synthetic 2D screening in the Verona screening program. A comparison cohort of women screened with FFDM (n = 14 423) in the previous year was included. Screening detection measures for the two groups were compared by calculating the proportions associated with each outcome, and the relative rates (RRs) were estimated with multivariate logistic regression. Results Cancer detection rate (CDR) for DBT plus synthetic 2D imaging was 9.30 per 1000 screening examinations versus 5.41 per 1000 screening examinations with FFDM (RR, 1.72; 95% confidence interval [CI]: 1.30, 2.29). CDR was significantly higher in patients screened with DBT plus synthetic 2D imaging than in those screened with FFDM among women classified as having low breast density (RR, 1.53; 95% CI: 1.13, 2.10) or high breast density (RR, 2.86; 95% CI: 1.42, 6.25). The positive predictive value (PPV) for recall was almost doubled with DBT plus synthetic 2D imaging: 23.3% versus 12.9% of recalled patients who were screened with FFDM (RR, 1.81; 95% CI: 1.34, 2.47). The recall rate was similar between groups (RR, 0.95; 95% CI: 0.84, 1.06), whereas the recall rate with invasive assessment was higher for DBT plus synthetic 2D imaging than for FFDM (RR, 1.93; 95% CI: 1.31, 2.03). The mean number of screening studies interpreted per hour was significantly lower for screening examinations performed with DBT plus synthetic 2D imaging (38.5 screens per hour) than with FFDM (60 screens per hour) (P < .001). Conclusion DBT plus synthetic 2D imaging increases CDRs with recall rates comparable to those of FFDM. DBT plus synthetic 2D imaging

The objectives of this paper are to describe the planned implementation and evaluation of the Building on Existing Tools to Improve Chronic Disease Prevention and Screening in Primary Care (BETTER 2) program which originated from the BETTER trial. The pragmatic trial, informed by the Chronic Care Model, demonstrated the effectiveness of an approach to Chronic Disease Prevention and Screening (CDPS) involving the use of a new role, the prevention practitioner. The desired goals of the program are improved clinical outcomes, reduction in the burden of chronic disease, and improved sustainability of the health-care system through improved CDPS in primary care. The BETTER 2 program aims to expand the implementation of the intervention used in the original BETTER trial into communities across Canada (Alberta, Ontario, Newfoundland and Labrador, the Northwest Territories and Nova Scotia). This proactive approach provides at-risk patients with an intervention from the prevention practitioner, a health-care professional. Using the BETTER toolkit, the prevention practitioner determines which CDPS actions the patient is eligible to receive, and through shared decision-making and motivational interviewing, develops a unique and individualized 'prevention prescription' with the patient. This intervention is 1) personalized; 2) addressing multiple conditions; 3) integrated through linkages to local, regional, or national resources; and 4) longitudinal by assessing patients over time. The BETTER 2 program brings together primary care providers, policy/decision makers and researchers to work towards improving CDPS in primary care. The target patient population is adults aged 40-65. The reach, effectiveness, adoption, implementation, maintain (RE-AIM) framework will inform the evaluation of the program through qualitative and quantitative methods. A composite index will be used to quantitatively assess the effectiveness of the prevention practitioner intervention. The CDPS actions

Cervical cancer screening is one of the most effective cancer prevention strategies, but most women in Africa have never been screened. In 2007, the Cameroon Baptist Convention Health Services, a large faith-based health care system in Cameroon, initiated the Women's Health Program (WHP) to address this disparity. The WHP provides fee-for-service cervical cancer screening using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC), prioritizing care for women living with HIV/AIDS. They also provide clinical breast examination, family planning (FP) services, and treatment for reproductive tract infection (RTI). Here, we document the strengths and challenges of the WHP screening program and the unique aspects of the WHP model, including a fee-for-service payment system and the provision of other women's health services. We retrospectively reviewed WHP medical records from women who presented for cervical cancer screening from 2007-2014. In 8 years, WHP nurses screened 44,979 women for cervical cancer. The number of women screened increased nearly every year. The WHP is sustained primarily on fees-for-service, with external funding totaling about $20,000 annually. In 2014, of 12,191 women screened for cervical cancer, 99% received clinical breast exams, 19% received FP services, and 4.7% received treatment for RTIs. We document successes, challenges, solutions implemented, and recommendations for optimizing this screening model. The WHP's experience using a fee-for-service model for cervical cancer screening demonstrates that in Cameroon VIA-DC is acceptable, feasible, and scalable and can be nearly self-sustaining.

Expanded newborn screening: social and ethical issues.

PubMed

Dhondt, Jean-Louis

2010-10-01

Newborn screening and genetic testing have expanded rapidly in the last decade with the advent of multiplex (e.g., tandem mass spectrometry) and/or DNA technologies. However, screening panels include a large number of disorders, which may not meet all of the traditional screening criteria, established in late 1960s, and used for years to justify screening programs. After a period of expansion driven by technological advances, many reports have reconsidered the justification of expanded programs. Many factors have contributed to test-panel discrepancies between countries. The test-panel review methodology, the way health benefits are weighed against harms, and the socioeconomic-political environment all play a role. Expansion of screening also requires reconsideration of the infrastructure (ideally, in the context of national plans for rare diseases) to support testing, counselling, education, treatment, and follow-up. Consequently, economic aspects cannot be ignored and can be a limitation for expansion. New ethical questions have emerged: risks of discrimination or stigmatization, respect of the autonomy of persons to make decisions, parental anxiety resulting from a false positive test (especially when reporting to parents screening results for untreatable conditions identified as by-products of screening), etc. For disorders where there is not yet confirmation of benefit, it may be prudent to recommend pilot screening and to have a mechanism that can be used to adapt or even to stop a program.

To determine whether health-related lifestyle factors are associated with attendance at a population-based invitational mammography screening program in southern Sweden, data on health-related lifestyle factors (smoking, alcohol use, physical activity, BMI, diet, self-rated health, and stress) were obtained from the Malmö Diet and Cancer Study and linked to the Malmö mammography register (Sweden, 1992-2009). Women (n=11 409) who were free from breast cancer at study entry were included in the cohort, and mammography attendance was followed from cohort entry to 31 December 2009. Generalized estimating equations were used to account for repeated measures within patients. Adjusted odds ratios (OR) and 95% confidence intervals (CI) are reported. Nonattendance occurred in 8% of the 69 746 screening opportunities that were observed. Nonattendance was more common among women who were current or former smokers [OR=1.60 (1.45-1.76) and OR=1.15 (1.05-1.28)], had not used alcohol in the past year [OR=1.55 (1.32-1.83)], were less physically active outside of work [OR=1.10 (1.00-1.20)], had high physical activity at work (OR=1.13, 95% CI: 1.00-1.28), were vegetarians or vegans [OR=1.49 (1.11-1.99)], had not used dietary supplements [OR=1.11 (1.01-1.21)], had poor self-rated health [OR=1.24 (1.14-1.36)], and were experiencing greater stress [OR=1.25 (1.14-1.36)]. In this cohort, nonattendance was associated with smoking, alcohol abstinence, physical activity, poor self-rated health, stress, and following a vegetarian/vegan diet. These findings generally support the notion that women with less healthy lifestyles are less likely to engage in mammography screening.

Objectives. The DuPage Patient Navigation Collaborative evaluated the Patient Navigation Research Program (PNRP) model for uninsured women receiving free breast or cervical cancer screening through the Illinois Breast and Cervical Cancer Program in DuPage County, Illinois. Methods. We used medical records review and patient surveys of 477 women to compare median follow-up times with external Illinois Breast and Cervical Cancer Program and Chicago PNRP benchmarks of performance. We examined the extent to which we mitigated community-defined timeliness risk factors for delayed follow-up, with a focus on Spanish-speaking participants. Results. Median follow-up time (29.0 days for breast and 56.5 days for cervical screening abnormalities) compared favorably to external benchmarks. Spanish-speaking patients had lower health literacy, lower patient activation, and more health care system distrust than did English-speaking patients, but despite the prevalence of timeliness risk factors, we observed no differences in likelihood of delayed (> 60 days) follow-up by language. Conclusions. Our successful replication and scaling of the PNRP navigation model to DuPage County illustrates a promising approach for future navigator research. PMID:25713942

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) of the Centers for Disease Control and Prevention (CDC) is implemented through cooperative agreements with state health departments, US territories, and tribal health organizations (grantees). Grantees typically contract with clinicians and other providers to deliver breast and cervical cancer screening and diagnostic services. As required by the CDC, grantees report biannually a subset of patient and clinical level program data known as the Minimum Data Elements. Rigorous processes are in place to ensure the completeness and quality of program data collection. In this article, the authors describe the NBCCEDP data-collection processes and data management system and discusses how data are used for 1) program monitoring and improvement, 2) evaluation and research, and 3) policy development and analysis. They also provide 2 examples of how grantees use data to improve their performance. PMID:25099900

Objectives Information on the process and method of service delivery is sparse for hepatitis B surface antigen (HBsAg) testing, and no systematic study has evaluated the relative effectiveness or cost-effectiveness of different HBsAg screening models. To address this need, we compared five specific community-based screening programs. Methods We funded five HBsAg screening programs to collect information on their design, costs, and outcomes of participants during a six-month observation period. We categorized programs into four types of models. For each model, we calculated the number screened, the number screened as per Centers for Disease Control and Prevention (CDC) recommendations, and the cost per screening. Results The models varied by cost per person screened and total number of people screened, but they did not differ meaningfully in the proportion of people screened following CDC recommendations, the proportion of those screened who tested positive, or the proportion of those who newly tested positive. Conclusions Integrating screening into outpatient service settings is the most cost-effective method but may not reach all people needing to be screened. Future research should examine cost-effective methods that expand the reach of screening into communities in outpatient settings. PMID:21800750

Food insecurity is associated with many poor health outcomes yet is not routinely addressed in clinical settings. The purpose of this study was to implement a food insecurity screening and referral program in Student-run Free Clinics (SRFC) and to document the prevalence of food insecurity screening in this low-income patient population. All patients seen in three SRFC sites affiliated with one institution in San Diego, California were screened for food insecurity using the 6-item United States Department of Agriculture (USDA) Food Security Survey between January and July 2015 and referred to appropriate resources. The percentage of patients who were food insecure was calculated. The screening rate was 92.5% (430/463 patients), 74.0% (318/430) were food insecure, including 30.7% (132/430) with very low food security. A food insecurity registry and referral tracking system revealed that by January 2016, 201 participants were receiving monthly boxes of food onsite, 66 used an off-site food pantry, and 64 were enrolled in the Supplemental Nutrition Assistance Program (SNAP). It is possible to implement a food insecurity screening and referral program into SRFCs. The prevalence of food insecurity in this population was remarkably high yet remained largely unknown until this program was implemented. Other health care settings, particularly those with underserved patient populations, should consider implementing food insecurity screening and referral programs.

Diabetic teleretinal screening programs have been utilized successfully across the world to detect diabetic retinopathy (DR) and are well validated. Less information, however, exists on the ability of teleretinal imaging to detect nondiabetic ocular pathology. This study performed a retrospective evaluation to assess the ability of a community-based diabetic teleretinal screening program to detect common ocular disease other than DR. A retrospective chart review of 1,774 patients who underwent diabetic teleretinal screening was performed. Eye clinic notes from the Veterans Health Administration's electronic medical record, Computerized Patient Record System, were searched for each of the patients screened through teleretinal imaging. When a face-to-face examination note was present, the physical findings were compared to those obtained through teleretinal imaging. Sensitivity, specificity, and positive and negative predictive values were calculated for suspicious nerve, cataract, and age-related macular degeneration. A total of 903 patients underwent a clinical examination. The positive predictive value was highest for cataract (100%), suspicious nerve (93%), and macular degeneration (90%). The negative predictive value and the percent agreement between teleretinal imaging and a clinical examination were over 90% for each disease category. A teleretinal imaging protocol may be used to screen for other common ocular diseases. It may be feasible to use diabetic teleretinal photographs to screen patients for other potential eye diseases. Additional elements of the eye workup may be added to enhance accuracy of disease detection. Further study is necessary to confirm this initial retrospective review.

As primary HPV screening programs are rolled out, methods are needed for routine quality assurance of HPV laboratory analyzes. To explore the use of similar design for audit as currently used in cytology-based screening, to estimate the clinical sensitivity to identify women at risk for CIN 3 or worse (CIN3+). Population-based cohort study conducted within the cervical screening program in Stockholm, Sweden, in 2011-2012. All women with histopathologically confirmed CIN3+ in the following two years were identified by registry analysis. Primary HPV and cytology screening results were collected. For women who had not been HPV tested, biobanked cytology samples were HPV-tested. If the original HPV result had been negative, the sample and subsequent biopsies were analyzed with broad HPV typing (general primer PCR and Luminex). 154 women had a biobanked prediagnostic cytology sample taken up to 2 years before a histopathologically confirmed CIN3+. The high-risk HPV-positivity was 97% (148/154 women), whereas 143/154 (94%) women had had a cytological abnormality. Among the six HPV-negative samples, one sample was HPV 33 positive in repeat testing whereas the other five cases were HPV-negative also on repeat testing, but HPV-positive in the subsequent tumor tissue. A sensitivity of the HPV test that is higher than the sensitivity of cytology suggests adequate quality of the testing. Regular audits of clinical sensitivity, similar to those of cytology-based screening, should be used also in HPV-based screening programs, in order to continuously monitor the performance of the analyzes.

To compute a ratio between the estimated numbers of lives saved from breast cancer death and the number of women diagnosed with a breast cancer that never would have been diagnosed during the woman's lifetime had she not attended screening (epidemiologic over-diagnosis) in the Norwegian Breast Cancer Screening Program. The Norwegian Breast Cancer Screening Program invites women aged 50-69 to biennial mammographic screening. Results from published studies using individual level data from the programme for estimating breast cancer mortality and epidemiologic over-diagnosis comprised the basis for the ratio. The mortality reduction varied from 36.8% to 43% among screened women, while estimates on epidemiologic over-diagnosis ranged from 7% to 19.6%. We computed the average estimates for both values. The benefit-detriment ratio, number of lives saved, and number of women over-diagnosed were computed for different scenarios of reduction in breast cancer mortality and epidemiologic over-diagnosis. For every 10,000 biennially screened women, followed until age 79, we estimated that 53-61 (average 57) women were saved from breast cancer death, and 45-126 (average 82) were over-diagnosed. The benefit-detriment ratio using average estimates was 1:1.4, indicating that the programme saved about one life per 1-2 women with epidemiologic over-diagnosis. The benefit-detriment ratio estimates of the Norwegian Breast Cancer Screening Program, expressed as lives saved from breast cancer death and epidemiologic over-diagnosis, should be interpreted with care due to substantial uncertainties in the estimates, and the differences in the scale of values of the events compared. © The Author(s) 2016.

To assess knowledge of cardiovascular disease (CVD) risk factors among a group of health screening participants and to compare knowledge between participants with high and low CVD risk. Cross-sectional pilot study. Jonesboro, AR, during June 2007. 121 adult volunteers participating in a community health screening. 34-item self-administered written questionnaire. Ability to identify CVD risk factors and healthy values for CVD risk factors and the differences in these abilities between participants with high and low CVD risk. Participants demonstrated good knowledge of traditional CVD risk factors such as high blood pressure, high cholesterol, lack of exercise, and overweight or obese status. Knowledge of other CVD risk factors and healthy values for major CVD risk factors was limited. Participants with high CVD risk were significantly more likely to correctly identify high triglycerides as a CVD risk factor and to identify healthy values for fasting blood glucose and total cholesterol compared with participants with low CVD risk. Overall, participants lacked knowledge of the risk factor status and healthy values for many CVD risk factors. Participants with high CVD risk may have better knowledge of some CVD risk factors than participants with low CVD risk. These findings highlight the need for more education to improve knowledge in both risk groups.

Colorectal cancer (CRC) is the 2nd most common cancer in women worldwide. In Italy, only 50% of people invited to get the Fecal Occult Blood Test (FOBT) decided to do it. Women's participation in breast and cervical screening is, instead, very high (>70%). The aim of our study was to investigate the beliefs, the feelings and the psychological factors that could influence the participation of women in CRC screening. We conducted a cross sectional study, in the Hospital of Siena, Central Italy, in 2011. We administered a questionnaire to 507 women of all ages, who attended mammography or clinical breast examination. The adherence to CRC screening was analyzed only in the group of 207 older women (age >50 years). We performed descriptive, bivariate and logistic regression analysis to identify whether an association was present between participant characteristics, willingness and adherence to screening. Family history of colorectal cancer (OR 4.3; p<0.007) and the General Practitioner's advice (OR: 3.4; p<0.003) were associated with a greater adherence to screening (colonoscopy). The embarrassment was another factor related to colonoscopy compliance (OR: 0.34; p<0.016). Family history of CRC, pain or embarassment and GP's advice are the factors that correlated more strongly (positively or negatively) with adherence to colorectal cancer screening. These elements should be further analyzed to choose the best solution to improve the adherence in campaigns on colorectal cancer.

Interventions tailored to sociopsychological factors associated with health behaviors have promise for reducing colorectal cancer screening disparities, but limited research has assessed their impact in multiethnic populations. We examined whether an interactive multimedia computer program (IMCP) tailored to expanded health belief model sociopsychological factors could promote colorectal cancer screening in a multiethnic sample. We undertook a randomized controlled trial, comparing an IMCP tailored to colorectal cancer screening self-efficacy, knowledge, barriers, readiness, test preference, and experiences with a nontailored informational program, both delivered before office visits. The primary outcome was record-documented colorectal cancer screening during a 12-month follow-up period. Secondary outcomes included postvisit sociopsychological factor status and discussion, as well as clinician recommendation of screening during office visits. We enrolled 1,164 patients stratified by ethnicity and language (49.3% non-Hispanic, 27.2% Hispanic/English, 23.4% Hispanic/Spanish) from 26 offices around 5 centers (Sacramento, California; Rochester and the Bronx, New York; Denver, Colorado; and San Antonio, Texas). Adjusting for ethnicity/language, study center, and the previsit value of the dependent variable, compared with control patients, the IMCP led to significantly greater colorectal cancer screening knowledge, self-efficacy, readiness, test preference specificity, discussion, and recommendation. During the followup period, 132 (23%) IMCP and 123 (22%) control patients received screening (adjusted difference = 0.5 percentage points, 95% CI -4.3 to 5.3). IMCP effects did not differ significantly by ethnicity/language. Sociopsychological factor tailoring was no more effective than nontailored information in encouraging colorectal cancer screening in a multiethnic sample, despite enhancing sociopsychological factors and visit behaviors associated with screening.

How to Improve the Quality of Screening Endoscopy in Korea: National Endoscopy Quality Improvement Program.

PubMed

Cho, Yu Kyung

2016-07-01

In Korea, gastric cancer screening, either esophagogastroduodenoscopy or upper gastrointestinal series (UGIS), is performed biennially for adults aged 40 years or older. Screening endoscopy has been shown to be associated with localized cancer detection and better than UGIS. However, the diagnostic sensitivity of detecting cancer is not satisfactory. The National Endoscopy Quality Improvement (QI) program was initiated in 2009 to enhance the quality of medical institutions and improve the effectiveness of the National Cancer Screening Program (NCSP). The Korean Society of Gastrointestinal Endoscopy developed quality standards through a broad systematic review of other endoscopic quality guidelines and discussions with experts. The standards comprise five domains: qualifications of endoscopists, endoscopic unit facilities and equipment, endoscopic procedure, endoscopy outcomes, and endoscopic reprocessing. After 5 years of the QI program, feedback surveys showed that the perception of QI and endoscopic practice improved substantially in all domains of quality, but the quality standards need to be revised. How to avoid missing cancer in endoscopic procedures in daily practice was reviewed, which can be applied to the mass screening endoscopy. To improve the quality and effectiveness of NCSP, key performance indicators, acceptable quality standards, regular audit, and appropriate reimbursement are necessary.

Since 1996, vision screening of three to six-year-old children is conducted every year in Iran. We present outcomes of project review held in August 2006. Kindergarten teachers examined vision by using Snellen's illiterate 'E' chart. They used torchlight to detect strabismus. On a repeat test, if either eye had vision < 20/30, the child was referred to the optometrist. A pediatric ophthalmologist examined and managed children with strabismus or amblyopia. Provincial managers supervised the screening program. The evaluator team assessed the coverage, yield, quality and feasibility, and cost-effectiveness of vision screening, as well as magnitude of amblyopia, and its risk factors. In 2005, 1.4 million (67%) children were examined in all provinces of Iran. Opticians examined 90,319 (61%) children with defective vision that were referred to them. The prevalence of uncorrected refractive error, strabismus and amblyopia was 3.82% (95% CI 3.79 - 3.85), 0.39% (95% CI 0.38 - 0.40) and 1.25% (95% CI 1.24 - 1.26) respectively. Validity test of 7,768 children had a sensitivity of 74.5% (95% CI 72.7 - 76.3) and specificity of 97.2% (95% CI 96.7 - 97.7). The cost of amblyopia screening was US $ 1.5 per child. While the cost of screening and treating one child with amblyopia was US $ 245. A review of the vision screening of children in Iran showed it with screening and useful exercise and had a yield of 1:21. The coverage of vision screening was low and the management of children with amblyopia, low vision and refractive error needed strengthening.

Adults with serious mental illness have a mortality rate two to three times higher than the overall US population, much of which is due to somatic conditions, especially cardiovascular disease. Given the disproportionately high prevalence of cardiovascular risk factors in the population with SMI, screening for these conditions is an important first step for timely diagnosis and appropriate treatment. This comprehensive literature review summarizes screening rates for cardiovascular risk factors in the population with serious mental illness. Relevant articles published between 2000 and 2013 were identified using the EMBASE, PsychInfo, PubMed, SCOPUS and Web of Science databases. We reviewed 10 studies measuring screening rates for obesity, diabetes, dyslipidemia, and hypertension in the population with serious mental illness. Two reviewers independently extracted information on screening rates, study population, and study setting. Rates of screening varied considerably by time period, study population, and data source for all medical conditions. For example, rates of lipid testing for antipsychotic users ranged from 6% to 85%. For some conditions, rates of screening were consistently high. For example, screening rates for hypertension ranged from 79% - 88%. There is considerable variation in screening of cardiovascular risk factors in the population with serious mental illness, with significant need for improvement in some study populations and settings. Implementation of standard screening protocols triggered by diagnosis of serious mental illness or antipsychotic use may be promising avenues for ensuring timely diagnosis and treatment of cardiovascular risk factors in this population.

The purpose of this study was to evaluate patient factors such as knowledge, attitude, motivation, perception, socio-economic status and travel time to health facilities and assess how these factors affected patients' decision to pursue cervical cancer screening with visual inspection with acetic acid (VIA). A total of 80 women of childbearing age who visited Kenjeran and Balongsari Public Health Centers for health assessments were involved in this study. Patients who agreed to participate in the study underwent a verbal questionnaire to evaluate various factors. Bivariate analysis concluded that knowledge, attitude, motivation, perception, socioeconomic status, and travel time to health facilities were significantly different between women who received VIA screening and women who did not receive VIA screening ( p < 0.05). The factors of knowledge, attitudes, motivation, perception, socio-economic status, and the travel time to health facilities accounted for 2.920-fold, 2.043-fold, 3.704-fold, 2.965-fold, 3.198-fold and 2.386-fold possibility, respectively, of patients to pursue cervical cancer screening with VIA. Multivariate analysis showed that perception, socio-economic status, and travel time to health facilities were the most important factors influencing whether or not women pursued VIA screening. Knowledge, attitude, motivation, perception, socio-economic status, and travel time to health facilities appears to affect women's' decision to pursue cervical cancer screening with VIA, with the largest intake being the motivational factor.

This study explores whether, and how, motivations for two screen viewing predicted social interaction behaviors and subsequent viewing intention of TV programs. A total of 453 respondents who responded that they use social networking sites (SNSs) via smartphones and actively watch entertainment programs completed an online survey questionnaire. In agreement with uses and gratifications assumptions, motivations for TSV predicted distinctive sets of social interaction behaviors, which mediated the influence of motivations on viewing intentions. Respondents' two screen viewing was meaningfully related with social interaction, engagement with programs, information seeking, and passing time. Results suggest that two screen viewing could provide shared experiences nourishing social capital and reintegrate TV audiences by social adhesive resulting from TV with SNSs.

Effectiveness of traveller screening for emerging pathogens is shaped by epidemiology and natural history of infection

Gostic, Katelyn M; Kucharski, Adam J; Lloyd-Smith, James O

2015-01-01

During outbreaks of high-consequence pathogens, airport screening programs have been deployed to curtail geographic spread of infection. The effectiveness of screening depends on several factors, including pathogen natural history and epidemiology, human behavior, and characteristics of the source epidemic. We developed a mathematical model to understand how these factors combine to influence screening outcomes. We analyzed screening programs for six emerging pathogens in the early and late stages of an epidemic. We show that the effectiveness of different screening tools depends strongly on pathogen natural history and epidemiological features, as well as human factors in implementation and compliance. For pathogens with longer incubation periods, exposure risk detection dominates in growing epidemics, while fever becomes a better target in stable or declining epidemics. For pathogens with short incubation, fever screening drives detection in any epidemic stage. However, even in the most optimistic scenario arrival screening will miss the majority of cases.

Changes in geographic variation in the uptake of cervical cancer screening in Taiwan: possible effects of "leadership style factor"?

PubMed

Chiou, Shu-Ti; Lu, Tsung-Hsueh

2014-01-01

Wennberg proposed the "practice style factor" to explain the large variations in the use of medical care. As a corollary, we propose the "leadership style factor" of the director of the city/county bureau of public health to explain changes in geographic variation in the uptake of cervical cancer screening. We first calculated the triennial Pap smear rates for women aged 30-69 years from 1997 through 2010 for each city/county in Taiwan and the rate difference and rate ratio between the highest and the lowest city/county to illustrate the geographic variation in the uptake of cervical cancer screening. We then created an expert panel to conduct a hypothesis generation process to examine the possible effects of "leadership style factors" in explaining the changes. The Pap smear rate in Taiwan as a whole was 35% in 1997 and increased to 56% in 2001, and was then stable until 2010 (55%). In 2002, the geographic variation in the Pap smear rate was the smallest, ranging from 49% in Penghu County to 63% in I-lan County, with a rate ratio of 1.28. Unfortunately, the rate ratio increased to 1.49 in 2010, the rate being lowest in Penghu County (42%) and highest in Tainan City (63%). We identified four cities/counties with unique patterns of change in Pap smear rates, which were highly associated with the leadership style of the director of the city/county bureau of public health. Despite the launch of an organized cancer screening program in Taiwan, geographic variation in the uptake of cervical cancer screening still exists and has increased during the past decade. The "leadership style factor" of the director of the city/county bureau of public health might play a plausible role in explaining the pattern of change in geographic variation in the use of cervical cancer screening in Taiwan.

Congenital hypothyroidism (CH) is a common cause of mental retardation; it has a worldwide incidence ranging from 1:3000 to 1:4500 live births. Predictably, an increase in the reported incidence of primary CH occurs when the cut-off levels of thyroid-stimulating hormone are lowered. We aimed to evaluate the results of a congenital hypothyroidism screening program and current status in this study. Analysis results of 1300 infants who were referred to the endocrinology polyclinic because of suspected CH within the scope of the Ministry of Health National Neonatal Screening Program were retrospectively evaluated. The diagnosis of CH and initiation of treatment were both done in 223 (18.5%) and 10 (0.8%) infants as a result of the initial evaluation and follow-up, respectively. The mean capillary and venous thyroid-stimulating hormone (TSH) levels of 223 patients were 40.78 (5.5-100) μIU/mL and 67.26 (10.7-100) μIU/mL, respectively. These patients' mean heel prick time was 8.65 (0-30, median: 7) days. The mean age of the 223 infants whose treatment was initiated as a result of the initial evaluation was 19.87 (4-51, median: 20) days, and the mean age of the infants whose treatment was started at follow-up was 43.71 (29-65) days. The duration between heel prick time and venous TSH time was 11.10 (2-28, median: 11) days and was longer than planned (3-5 days). Although the duration for the diagnosis and initiation of CH treatment were markedly reduced with the implementation of the screening program in Turkey compared to those before the implementation of the screening program, we have not yet achieved the ideal time (≤14 days).

Sweden has not yet implemented a national screening program for colorectal cancer, but a nationwide study is ongoing; the Screening of Swedish Colons (SCREESCO). Previous research shows that the use of health care services, together with several health-related outcomes, is associated with an individual's level of health literacy. However, the relation between health literacy and participation in colorectal cancer screening has produced varying results reported within the few studies addressing this issue and therefore, further research is warranted. The aim was to explore health literacy and views about being invited to screening, among participants and non-participants in a national colorectal cancer screening program. They were randomly sampled to fecal immunochemical test or colonoscopy and a mixed methods approach was applied, using questionnaires, focus group discussions and interviews. The majority of individuals, whether they were participants or non-participants in the SCREESCO program, had an acceptable level of health literacy and no significant differences in health literacy levels between the groups were found. Participants expressed that it was important and appreciated to be able to choose information sources on an individual basis. Among non-participants, the importance of receiving invitations with a clear message that quickly draws one's attention was highlighted. However, both groups expressed a positive outlook towards the invitation. The mixed methods approach revealed that findings from interviews and focus group discussions corresponded to items in the health literacy scales. A majority of individuals displayed acceptable levels of health literacy, regardless of whether they chose to participate or not. Similarities between the groups were seen in the qualitative findings regarding views of the invitation. Currently, the SCREESCO invitation letter is distributed by regular mail, but in the future a more dynamic approach could be valuable to

Breast cancer is less likely to be diagnosed at the earliest stage in Hispanic/Latino (Hispanic) women compared to non-Hispanic White women, even after accounting for differences in age, socioeconomic status, and method of detection. Moffitt Cancer Center created a comprehensive health education program called Yo me cuido (®) (YMC) to address and reduce breast cancer disparities among Spanish- and English-speaking Hispanic women by providing breast cancer and healthy lifestyles awareness and education, and promoting breast cancer screenings, reminders, and referrals for women 40 years and older. The purpose of this paper is to showcase the innovative approaches and methods to cancer prevention and early detection of the YMC program, and to promote it as an effective tool for improving outcomes in community health education, outreach, and engagement activities with Hispanic populations. Key components of the program include educational workshops, mammogram referrals, and a multimedia campaign. The YMC program is unique because of its approaches in reaching the Hispanic population, such as delivering the program with compassionate services to empower participants to live a healthier lifestyle. Additionally, direct follow-up for mammography screenings is provided by program staff. From 2011 to 2013, YMC has educated 2,226 women and 165 men through 93 workshops. About 684 (52 %) women ages 40 and older have had a screening mammogram within their first year of participating in the program. The YMC program is an innovative cancer education and outreach program that has demonstrated a positive impact on the lives of the Hispanic community in the Tampa Bay region.

This article describes the development of the Cultivando La Salud program, an intervention to increase breast and cervical cancer screening for Hispanic farmworker women. Processes and findings of intervention mapping (IM), a planning process for development of theory and evidence-informed program are discussed. The six IM steps are presented: needs assessment, preparation of planning matrices, election of theoretic methods and practical strategies, program design, implementation planning, and evaluation. The article also describes how qualitative and quantitative findings informed intervention development. IM helped ensure that theory and evidence guided (a) the identification of behavioral and environmental factors related to a target health problem and (b) the selection of the most appropriate methods and strategies to address the identified determinants. IM also guided the development of program materials and implementation by lay health workers. Also reported are findings of the pilot study and effectiveness trial.

Screening of modifiable cardiovascular disease (CVD) risk factors is recommended but not routinely provided for HIV-infected patients, especially in low-resource settings. Potential concerns include limited staff time and low patient acceptability, but little empirical data exists. As part of a pilot study of screening in a large urban HIV clinic in Swaziland, we conducted a time-motion study to assess the impact of screening on patient flow and HIV service delivery and exit interviews to assess patient acceptability. A convenience sample of patients ≥40 years of age attending routine HIV clinic visits was screened for hypertension, diabetes, hyperlipidemia and tobacco smoking. We observed HIV visits with and without screening and measured time spent on HIV and CVD risk factor screening activities. We compared screened and unscreened patients on total visit time and time spent receiving HIV services using Wilcoxon rank-sum tests. A separate convenience sample of screened patients participated in exit interviews to assess their satisfaction with screening. We observed 172 patient visits (122 with CVD risk factor screening and 50 without). Screening increased total visit time from a median (range) of 4 minutes (2 to 11) to 15 minutes (9 to 30) (p < 0.01). Time spent on HIV care was not affected: 4 (2 to 10) versus 4 (2 to 11) (p = 0.57). We recruited 126 patients for exit interviews, all of whom indicated that they would recommend screening to others. Provision of CVD risk factor screening more than tripled the length of routine HIV clinic visits but did not reduce the time spent on HIV services. Programme managers need to take longer visit duration into account in order to effectively integrate CVD risk factor screening and counselling into HIV programmes. © 2018 The Authors.

Latinos are a diverse population comprised of multiple countries of origin with varying cultural profiles. This study examines differences in colonoscopy completion across place of birth and migration-related factors in a sample of predominantly Dominican and Puerto Rican Latinos living in New York City after receiving a recommendation for colonoscopy screening and navigation services. The sample included 702 Latinos recruited for two cancer screening projects targeting Latinos eligible for colonoscopy who seek healthcare in New York City. Participants completed a survey that included sociodemographic, health-related questions, psychosocial assessments and cancer screening practices, in Spanish or English. Migration, acculturation, and language factors were found to predict colonoscopy completion. The results indicated that Latinos born in the Dominican Republic and Central America were more likely to complete a screening colonoscopy than their counterparts born in the US. Further, those who emigrated at an older age, who have resided in the US for less than 20 years, preferred Spanish and those with lower US acculturation levels were also more likely to complete a screening colonoscopy. The findings suggest that Latinos who are less acculturated to the US are more likely to complete a screening colonoscopy after receiving a physician recommendation for colonoscopy screening. The results provide important information that can inform clinical practice and public health interventions. Continued attention to cultural and migration influences are important areas for cancer screening intervention development.

In 1996, the U.S. Congress passed the Food Quality Protection Act and amended the Safe Drinking Water Act (SDWA) requiring the U.S. Environmental Protection Agency (EPA) to implement a screening program to investigate the potential of pesticide chemicals and drinking water contaminants to adversely affect endocrine pathways. Consequently, the EPA launched the Endocrine Disruptor Screening Program (EDSP) to develop and validate estrogen, androgen, and thyroid (EAT) pathway screening assays and to produce standardized and harmonized test guidelines for regulatory application. In 2009, the EPA issued the first set of test orders for EDSP screening and a total of 50 pesticide actives and 2 inert ingredients have been evaluated using the battery of EDSP Tier 1 screening assays (i.e., five in vitro assays and six in vivo assays). To provide a framework for retrospective analysis of the data generated and to collect the insight of multiple stakeholders involved in the testing, more than 240 scientists from government, industry, academia, and non-profit organizations recently participated in a workshop titled "Lessons Learned, Challenges, and Opportunities: The U.S. Endocrine Disruptor Screening Program." The workshop focused on the science and experience to date and was organized into three focal sessions: (a) Performance of the EDSP Tier 1 Screening Assays for Estrogen, Androgen, and Thyroid Pathways; (b) Practical Applications of Tier 1 Data; and (c) Indications and Opportunities for Future Endocrine Testing. A number of key learnings and recommendations related to future EDSP evaluations emanated from the collective sessions.

Data were extracted from the National Cancer Screening Program databases for participants who underwent FIT between 2009 and 2010. We compared positivity rates, cancer detection rates, interval cancer rates, positive predictive value, sensitivity, and specificity for FIT during the spring, summer, fall, and winter seasons in Korea. In total, 4,788,104 FIT results were analyzed. FIT positivity rate was lowest during the summer months. In the summer, the positive predictive value of FIT was about 1.1 times (adjusted odds ratio (aOR) 1.08, 95% confidence interval (CI) 1.00-1.16) higher in the overall FIT group and about 1.3 times (aOR 1.29, 95% CI 1.10-1.50) higher in the quantitative FIT group, compared to those in the other seasons. Cancer detection rates, however, were similar regardless of season. Interval cancer risk was significantly higher in the summer for both the overall FIT group (aOR 1.16, 95% CI 1.07-1.27) and the quantitative FIT group (aOR 1.31, 95% CI 1.12-1.52). In addition, interval cancers in the rectum and distal colon were more frequently detected in the summer and autumn than in the winter. The positivity rate of FIT was lower in the summer, and the performance of the FIT screening program was influenced by seasonal variations in Korea. These results suggest that more efforts to reduce interval cancer during the summer are needed in population-based screening programs using FIT, particularly in countries with high ambient temperatures.

Lung cancer risk prediction models have the potential to make programs more affordable; however, the economic evidence is limited. Participants in the National Lung Cancer Screening Trial (NLST) were retrospectively identified with the risk prediction tool developed from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. The high-risk subgroup was assessed for lung cancer incidence and demographic characteristics compared with those in the low-risk subgroup and the Pan-Canadian Early Detection of Lung Cancer Study (PanCan), which is an observational study that was high-risk-selected in Canada. A comparison of high-risk screening versus standard care was made with a decision-analytic model using data from the NLST with Canadian cost data from screening and treatment in the PanCan study. Probabilistic and deterministic sensitivity analyses were undertaken to assess uncertainty and identify drivers of program efficiency. Use of the risk prediction tool developed from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial with a threshold set at 2% over 6 years would have reduced the number of individuals who needed to be screened in the NLST by 81%. High-risk screening participants in the NLST had more adverse demographic characteristics than their counterparts in the PanCan study. High-risk screening would cost $20,724 (in 2015 Canadian dollars) per quality-adjusted life-year gained and would be considered cost-effective at a willingness-to-pay threshold of $100,000 in Canadian dollars per quality-adjusted life-year gained with a probability of 0.62. Cost-effectiveness was driven primarily by non-lung cancer outcomes. Higher noncurative drug costs or current costs for immunotherapy and targeted therapies in the United States would render lung cancer screening a cost-saving intervention. Non-lung cancer outcomes drive screening efficiency in diverse, tobacco-exposed populations. Use of risk selection can reduce the budget impact, and

The National Cancer Screening Program (NCSP) in Korea supports cancer screening for stomach, liver, colorectal, breast, and cervical cancer. This study was conducted to assess trends in participation rates among Korean men and women invited to undergo screening via the NCSP as part of an effort to guide future implementation of the program in Korea. Data from the NCSP for 2002 to 2012 were used to calculate annual participation rates with 95% confidence intervals (CI) by sex, insurance status, and age group for stomach, liver, colorectal, breast, and cervical cancer screening. In 2012, participation rates for stomach, liver, colorectal, breast, and cervical cancer screening were 47.3%, 25.0%, 39.5%, 51.9%, and 40.9%, respectively. The participation rates increased annually by 4.3% (95% CI, 4.0 to 4.6) for stomach cancer, 3.3% (95% CI, 2.5 to 4.1) for liver cancer, 4.1% (95% CI, 3.2 to 5.0) for colorectal cancer, 4.6% (95% CI, 4.1 to 5.0) for breast cancer, and 0.9% (95% CI, -0.7 to 2.5) for cervical cancer from 2002 to 2012. Participant rates for the NCSP for the five above-mentioned cancers increased annually from 2002 to 2012.

From 2003 to 2012, the Philadelphia High School STD Screening Program screened 126,053 students, identifying 8089 Chlamydia trachomatis (CT)/Neisseria gonorrhoeae (GC) infections. We examined sociodemographic and behavioral factors associated with CT/GC diagnoses among a sample of this high-risk population. Standardized interviews were given to infected students receiving in-school CT/GC treatment (2009-2012) and to uninfected students calling for results (2011-2012). Sex-stratified multivariable logistic models were created to examine factors independently associated with a CT/GC diagnosis. A simple risk index was developed using variables significant on multivariable analysis. A total of 1489 positive and 318 negative students were interviewed. Independent factors associated with a GC/CT diagnosis among females were black race (adjusted odds ratio [AOR], 2.27; confidence interval, 1.12-4.58), history of arrest (AOR, 2.26; 1.22-4.21), higher partner number (AOR, 1.75; 1.05-2.91), meeting partners in own neighborhood (AOR, 1.92; 1.29-2.86), and meeting partners in venues other than own school, neighborhood, or through friends ("all other"; AOR, 9.44; 3.70-24.09). For males, factors included early sexual debut (AOR, 1.99; 1.21-3.26) and meeting partners at "all other" venues (AOR, 2.76; 1.2-6.4); meeting through friends was protective (AOR, 0.63; 0.41-0.96). Meeting partners at own school was protective for both sexes (males: AOR, 0.33; 0.20-0.55; females: AOR, 0.65; 0.44-0.96). Although factors associated with a GC/CT infection differed between males and females in our sample, partner meeting place was associated with infection for both sexes. School-based screening programs could use this information to target high-risk students for effective interventions.

Many cardiac rehabilitation (CR) guidelines and position statements recommend screening for psychosocial risk factors, although there is wide variation in the recommended factors and recommended screening tools. Little is known about screening in CR in Australia. Cardiac rehabilitation coordinators at the 314 CR programs operating across Australia, drawn from the 2014 Australian Directory of Cardiac Rehabilitation Services were invited to participate in an online survey. Of 165 complete responses, 157 (95%) CR coordinators indicated that they screened at entry with 132 (80%) screening on exit. At CR entry, programs screened for - depression (83%), anxiety (75%), stress (75%), and sleep disturbance (57%). The use of standardised instruments by those screening at entry varied from 89% for depression to only 9% for sleep disturbance. Organisational, resource and personal barriers inhibited the routine screening for many psychosocial factors. Surveys such as this are useful for monitoring the rate of adoption of guideline recommendations and identifying barriers to implementation. Findings can also inform discussions about what should be included in minimum data sets for CR programs, and the identification of brief screening tools that have been validated not just in the general population but in cardiac patients.

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast and cervical cancer screening and diagnostic services to low-income and underserved women through a network of providers and health care organizations. Although the program serves women 40-64 years old for breast cancer screening and 21-64 years old for cervical cancer screening, the priority populations are women 50-64 years old for breast cancer and women who have never or rarely been screened for cervical cancer. From 1991 through 2011, the NBCCEDP provided screening and diagnostic services to more than 4.3 million women, diagnosing 54,276 breast cancers, 2554 cervical cancers, and 123,563 precancerous cervical lesions. A critical component of providing screening services is to ensure that all women with abnormal screening results receive appropriate and timely diagnostic evaluations. Case management is provided to assist women with overcoming barriers that would delay or prevent follow-up care. Women diagnosed with cancer receive treatment through the states' Breast and Cervical Cancer Treatment Programs (a special waiver for Medicaid) if they are eligible. The NBCCEDP has performance measures that serve as benchmarks to monitor the completeness and timeliness of care. More than 90% of the women receive complete diagnostic care and initiate treatment less than 30 days from the time of their diagnosis. Provision of effective screening and diagnostic services depends on effective program management, networks of providers throughout the community, and the use of evidence-based knowledge, procedures, and technologies.

HPV vaccination programs have not been shown to be cost-effective in countries with comprehensive Pap screening and surgery.

Pap screening combined with loop electrosurgical excision procedures (LEEP) is almost 100% effective in preventing cervical cancer mortality yet many countries with these procedures have now implemented broad HPV vaccination programs. HPV vaccines have not been demonstrated to be more effective or safer than Pap screening in the prevention of cervical cancer and Pap screening will still be required even in vaccinated women. The HPV vaccine costs Au$450 per person and it does not protect against ~30% of cancer. This investigation analyses the cost-effectiveness of using the HPV vaccine in countries where Pap screening and surgical procedures have already reduced cervical cancer mortality to very low rates. Cost-effectiveness of vaccination programs is being determined by mathematical models which are founded on many assumptions. It is necessary to examine the rigor of these assumptions to be certain of the health benefits that are predicted. In 2002 scientists concluded that HPV 16 and 18 were the central and independent cause of most cervical cancer. This conclusion was based on molecular technology. If HPV 16 and 18 infections are the central and independent cause of most cervical cancer then the incidence of HPV 16 and 18 should vary with the incidence and mortality of cervical cancer worldwide. This correlation does not exist. It is also observed that the majority of HPV 16/18 infections do not lead to cervical cancer. This indicates that other etiological or 'risk' factors are necessary for persistent HPV infection to progress to cancer. The benefits of HPV vaccines have been determined by using pre-cancerous lesions in young women as a surrogate for cervical cancer. This surrogate is found to be inadequate as an end-point for cervical cancer. Clinical trials have only provided speculative benefits for the efficacy of HPV vaccines against cancer and the long-term risks of the vaccine have not been established. Pap screening will still be required in vaccinated

Screen viscometer measurements give different information about polymer molecular weight and molecular weight distribution than intrinsic viscosity or relative viscosity measurements. This study shows that conventional screen viscometers measure elongation flow properties of solutions, and that for flexible polymers such as polyacrylamides, a sharp transition in conformation from a coiled to a stretched state is observed, which occurs at a Deborah number of 0.5. Conventional screen viscometers operate just above this critical Deborah number. Evidence for this transition in polymer conformation comes from measurements on a modified screen viscometer, from extensive work by Durst and Interhal on the sudden pressuremore » jumps during flow of polyacrylamide solutions through porous media, and from polymer kinetic theory modeling of molecular deformation in flow. ll references.« less

2015-02-01

This review assessed the effectiveness of diabetic retinopathy (DR) screening programs, using retinal photography in Australian urban and rural settings, and considered implications for public health strategy and policy. An electronic search of MEDLINE, PubMed, and Embase for studies published between 1 January 1996 and the 30 June 2013 was undertaken. Key search terms were "diabetic retinopathy," "screening," "retinal photography" and "Australia." Twelve peer-reviewed publications were identified. The 14 DR screening programs identified from the 12 publications were successfully undertaken in urban, rural and remote communities across Australia. Locations included a pathology collection center, and Indigenous primary health care and Aboriginal community controlled organizations. Each intervention using retinal photography was highly effective at increasing the number of people who underwent screening for DR. The review identified that prior to commencement of the screening programs a median of 48% (range 16-85%) of those screened had not undergone a retinal examination within the recommended time frame (every year for Indigenous people and every 2 years for non-Indigenous people in Australia). A median of 16% (range 0-45%) of study participants had evidence of DR. This review has shown there have been many pilot and demonstration projects in rural and urban Australia that confirm the effectiveness of retinal photography-based screening for DR.

Preeclampsia affects approximately 3% of all pregnancies and is a major cause of maternal and perinatal morbidity and death. In the last decade, extensive research has been devoted to early screening for preeclampsia with the aim of reducing the prevalence of the disease through pharmacologic intervention in the high-risk group starting from the first trimester of pregnancy. The purpose of this study was to develop a model for preeclampsia based on maternal demographic characteristics and medical history (maternal factors) and biomarkers. The data for this study were derived from prospective screening for adverse obstetric outcomes in women who attended for their routine first hospital visit at 11-13 weeks gestation in 2 maternity hospitals in England. We screened 35,948 singleton pregnancies that included 1058 pregnancies (2.9%) that experienced preeclampsia. Bayes theorem was used to combine the a priori risk from maternal factors with various combinations of uterine artery pulsatility index, mean arterial pressure, serum pregnancy-associated plasma protein-A, and placental growth factor multiple of the median values. Five-fold cross validation was used to assess the performance of screening for preeclampsia that delivered at <37 weeks gestation (preterm-preeclampsia) and ≥37 weeks gestation (term-preeclampsia) by models that combined maternal factors with individual biomarkers and their combination with screening by maternal factors alone. In pregnancies that experienced preeclampsia, the values of uterine artery pulsatility index and mean arterial pressure were increased, and the values of serum pregnancy-associated plasma protein-A and placental growth factor were decreased. For all biomarkers, the deviation from normal was greater for early than late preeclampsia; therefore, the performance of screening was related inversely to the gestational age at which delivery became necessary for maternal and/or fetal indications.

Cytology and core-needle biopsies are not always sufficient to exclude malignancy in benign breast lesions (BBL) that are at risk of developing cancer, and open biopsy often is mandatory. In screening programs, open biopsies performed for lesions that are at risk of developing malignancy are considered benign. The authors of this report evaluated the impact of the screen-detected BBL at risk of developing cancer that were counted in the quota of benign breast open biopsies in the Breast Cancer Screening Program of Verona. Benign open biopsies were subdivided into 4 groups according to their risk of developing cancer: Histo1, normal histology; Histo2, 'pure' BBL (fibroadenoma, fibrocystic disease, mastitis, adenosis); Histo3, BBL with a low risk of developing cancer (radial scar, papilloma, papillomatosis, phyllodes tumor, mucocele-like lesion); and Histo4, BBL with a high risk of developing cancer (atypical columnar cell hyperplasia, atypical ductal hyperplasia, atypical lobular hyperplasia). Of 510 open biopsies, 83 biopsies were benign, and the ratio of benign to malignant biopsies was 1:5. Histo1 was observed in 4.8% of all benign open biopsies, Histo2 was observed in 37.4%, Histo3 was observed in 31.3%, and Histo4 was observed 26.5%. BBL at risk of developing cancer may be numerous in screening programs. It is inappropriate to include BBL at risk of developing cancer in the overall benign open biopsy rate. The authors propose separating pure BBL from lesions at higher risk of developing cancer. To date, there is no evidence to support the premise that detecting high-risk proliferative lesions leads to benefits in terms of reduced mortality; however, these lesions need to be counted separately for future evaluations.

This study investigates the impact of and behavioral responses to cost sharing in Korea's National Cancer Screening Program, which provides free stomach and breast cancer screenings to those with an income below a certain cutoff. Free cancer screening substantially increases the screening take up rate, yielding more cancer detections. However, the increase in cancer detection is quickly crowded out by cancer detection through other channels such as diagnostic testing and private cancer screening. Further, compliers are much less likely to have cancer than never takers. Crowd-out and selection help explain why the program has been unable to reduce cancer mortality.

The population in northeast Thailand continues to present with hepatobiliary abnormalities, particularly periductal fibrosis (PDF) which is the result of chronic infection with liver fluke (Opisthorchis viverini; OV) and may lead to the development of cholangiocarcinoma (CCA). Although the prevalence of OV infection has been decreased due to a liver fluke control program over decades, the prevalence of PDF remains high. This study aimed to investigate demographic factors associated with PDF risk based on ultrasonography (US) screening. This cross-sectional study is part of the Cholangiocarcinoma Screening and Care Program (CASCAP), a prospective cohort study. Multiple logistic regression was used for data analysis. In 55,246 subjects, the overall prevalence of PDF was 33.0% (95%CI: 32.6 - 33.4). Males (33.9 %) were at higher risk for developing PDF than females (32.2 %) (ORcrude = 0.93; 95%CI: 0.89 - 0.96; p-value < 0.001). Factors associated with an increased PDF risk, in addition to OV infection, included old age (≥ 70 years) (ORadj =1.28, 95% CI: 1.14 - 1.44, <0.001) and hepatitis B infection (ORadj = 1.31, 95% CI: 1.11 - 1.55, p = 0.001). In contrast, number of praziquantel treatments (> 2 times) (ORadj = 0.54, 95% CI: 0.47 - 0.63, <0.001) and diabetes mellitus (ORadj =0.57, 95% CI: 0.49 - 0.65, <0.001) were significantly associated with a decreased PDF risk. Future US screening should closely examine older people and hepatitis B subjects for the purpose of PDF surveillance among high risk groups for CCA. However, the results of inverse associations require further investigation in order to confirm our findings.

The effectiveness of fecal immunochemical testing (FIT) in reducing colorectal cancer (CRC) mortality has not yet been fully assessed in a large, population-based service screening program. A prospective cohort study of the follow-up of approximately 5 million Taiwanese from 2004 to 2009 was conducted to compare CRC mortality for an exposed (screened) group and an unexposed (unscreened) group in a population-based CRC screening service targeting community residents of Taiwan who were 50 to 69 years old. Given clinical capacity, this nationwide screening program was first rolled out in 2004. In all, 1,160,895 eligible subjects who were 50 to 69 years old (ie, 21.4% of the 5,417,699 subjects of the underlying population) participated in the biennial nationwide screening program by 2009. The actual effectiveness in reducing CRC mortality attributed to the FIT screening was 62% (relative rate for the screened group vs the unscreened group, 0.38; 95% confidence interval, 0.35-0.42) with a maximum follow-up of 6 years. The 21.4% coverage of the population receiving FIT led to a significant 10% reduction in CRC mortality (relative rate, 0.90; 95% confidence interval, 0.84-0.95) after adjustments for a self-selection bias. This large, prospective Taiwanese cohort undergoing population-based FIT screening for CRC had the statistical power to demonstrate a significant CRC mortality reduction, although the follow-up time was short. Although such findings are informative for health decision makers, continued follow-up of this large cohort will be required to estimate the long-term impact of FIT screening if the covered population is expanded. © 2015 American Cancer Society.

Growth Monitoring and Promotion programs (GMP) have been intensively promoted to improve children's health in developing countries. It has been hoped that regularly weighing children would result in the early detection of growth falterers, and that the growth chart would serve as an educational tool to make that state apparent to both health workers and caretakers in order to trigger improved caring practices. Our objective was to review whether GMP answers the theoretical grounds of a screening and intervention program. A systematic literature review was performed. The WHO framework developed by Wilson and Jungner for planning and evaluating screening programs guided the analysis. Sixty-nine studies were retrieved. Overall, evidence is weak on the performance of GMP as a screening program for malnutrition through early detection of growth falterers. The main results are: (1) malnutrition remains a public health problem, but its importance is context specific; (2) the value of a low weight velocity to predict malnutrition is unknown and likely to vary in different contexts; (3) the performance of GMP for improving nutrition status of children and in reducing mortality and morbidity is unknown; (4) the performance of the screening is affected by the unreliability of weight measurements; (5) the promotional and educational effectiveness of GMP is low, in particular the growth chart is poorly understood by mothers; (6) the acceptability seems low in regards of low attendance rates; (7) evidence is lacking regarding cost-effectiveness. We conclude that there is too little scientific evidence to indiscriminately support international promotion of GMP. However GMP could constitute a valid strategy of public nutrition in specific situations. We indicate paths for further research and how prevention programs could be developed.

The authors evaluate the different organizational strategies of a congenital hypothyroidism screening program. Positive and negative aspects of laboratory screening tests (TSH only, T4-supplemental TSH, TSH and T4), organization strategies (centralization or decentralization), recall and first follow-up criteria are examined. The authors consider that the necessity for an early diagnostic confirmation can be associated with a precise etiologic diagnosis and an evaluation of the prenatal severity of congenital hypothyroidism factors. Some European and North-American experiences are compared with the activity of a regional Italian screening center.

Colorectal cancer screening: An updated review of the available options.

Colorectal cancer (CRC) is a significant cause of morbidity and mortality worldwide. However, colon cancer incidence and mortality is declining over the past decade owing to adoption of effective screening programs. Nevertheless, in some parts of the world, CRC incidence and mortality remain on the rise, likely due to factors including "westernized" diet, lifestyle, and lack of health-care infrastructure and resources. Participation and adherence to different national screening programs remain obstacles limiting the achievement of screening goals. Different modalities are available ranging from stool based tests to radiology and endoscopy with varying sensitivity and specificity. However, the availability of these tests is limited to areas with high economic resources. Recently, FDA approved a blood-based test (Epi procolon ® ) for CRC screening. This blood based test may serve to increase the participation and adherence rates. Hence, leading to increase in colon cancer detection and prevention. This article will discuss various CRC screening tests with a particular focus on the data regarding the new approved blood test. Finally, we will propose an algorithm for a simple cost-effective CRC screening program.

British Columbia undertook a colorectal cancer screening pilot program in 3 communities. Our objective was to assess the performance of 2-specimen fecal immunochemical testing in the detection of colorectal neoplasms in this population-based screening program. A prospective cohort of asymptomatic, average-risk people aged 50 to 74 years completed 2 quantitative fecal immunochemical tests every 2 years, with follow-up colonoscopy if the result of either test was positive. Participant demographics, fecal immunochemical test results, colonoscopy quality indicators and pathology results were recorded. Non-screen-detected colorectal cancer that developed in program participants was identified through review of data from the BC Cancer Registry. A total of 16 234 people completed a first round of fecal immunochemical testing, with a positivity rate of 8.6%; 5378 (86.0% of eligible participants) completed a second round before the end of the pilot program, with a positivity rate of 6.7%. Of the 1756 who had a positive test result, 1555 (88.6%) underwent colonoscopy. The detection rate of colorectal cancer was 3.5 per 1000 participants. The positive predictive value of the fecal immunochemical test was 4.9% (95% confidence interval [CI] 3.8%-6.0%) for colorectal cancer, 35.0% (95% CI 32.5%-37.2%) for high-risk polyps and 62.0% (95% CI 59.6%-64.4%) for all neoplasms. The number needed to screen was 283 to detect 1 cancer, 40 to detect 1 high-risk polyp and 22 to detect any neoplasm. Screening every 2 years with a 2-specimen fecal immunochemical test surpassed the current benchmark for colorectal cancer detection in population-based screening. This study has implications for other jurisdictions planning colorectal cancer screening programs.

The Massachusetts Department of Public Health's (MDPH) Office of HIV/AIDS (OHA) and Hinton State Laboratory Institute (HSLI) have offered HIV screening since 1985. Point-of-care screening and serum collection for laboratory-based testing is conducted at clinic and non-clinic-based sites across Massachusetts as part of an integrated communicable disease screening intervention. MDPH aimed to transition to a 4th generation HIV screening-based algorithm for testing all serum specimens collected at OHA-funded programs and submitted to the HSLI to detect acute HIV infections, detect and differentiate HIV-1 and HIV-2 infections, eliminate indeterminate results, reduce cost and turnaround time, and link newly diagnosed HIV+ individuals to care. The HSLI and OHA created a joint project management team to plan and lead the transition. The laboratory transitioned successfully to a 4th generation screening assay as part of a revised diagnostic algorithm. In the 12 months since implementation, a total of 7984 serum specimens were tested with 258 (3.2%) positive for HIV-1 and one positive for HIV-2. Eight were reported as acute HIV-1 infections. These individuals were linked to medical care and partner services in a timely manner. Turnaround time was reduced and the laboratory realized an overall cost savings of approximately 15%. The identification of eight acute HIV infections in the first year underscores the importance of using the most sensitive screening tests available. A multi-disciplinary program and laboratory team was critical to the success of the transition, and the lessons learned may be useful for other jurisdictions. Published by Elsevier B.V.

Evidence Does Not Support Clinical Screening of Literacy

PubMed Central

Wolf, Michael S.

2007-01-01

Limited health literacy is a significant risk factor for adverse health outcomes. Despite controversy, many health care professionals have called for routine clinical screening of patients’ literacy skills. Whereas brief literacy screening tools exist that with further evaluation could potentially be used to detect limited literacy in clinical settings, no screening program for limited literacy has been shown to be effective. Yet there is a noted potential for harm, in the form of shame and alienation, which might be induced through clinical screening. There is fair evidence to suggest that possible harm outweighs any current benefits; therefore, clinical screening for literacy should not be recommended at this time. PMID:17992564

Burden of colorectal cancer is rising in China. More attention and financial input have been paid to it by central government that colorectal cancer screening program has been carried out recently in many areas in China. Diversity of screening strategies and limited health resources render selecting the best strategy in a population-wide program a challenging task that economy was also required to be considered except safety and efficacy. To provide a reference for the subsequent further economic evaluation, here we reviewed the evidence available on the economic evaluation of colorectal cancer screening in China. Meanwhile, information related to screening strategies, participation and mid-term efficacy of screening, information and results on economic evaluation were extracted and summarized. Three of the four studies finally included evaluated strategies combining immunochemical fecel occult blood test (iFOBT) with high-risk factor questionnaire as initial screening, colonoscopy as diagnostic screening. There was a consensus regarding the efficacy and effectiveness of screening compared to no screening. Whereas the lack and poor comparability between studies, multi-perspective and multi-phase economic evaluation of colorectal cancer screening is needed, relying on current population-based screening program to conduct a comprehensive cost accounting.

To profile and compare the content and presentation of written communications related to informed decision-making about mammography. Materials from 16 screening programs organized at the national or regional level were analyzed according to five major information domains suggested by the international literature. A majority of countries provided information on the program (interval, cost and quality). There was considerable variability in comprehensiveness of elements in the domains, e.g., test characteristics (false positive/negative) and pros and cons of screening. The majority noted the likelihood of recall for further tests, few commented on the risks of additional tests or finding unimportant tumors. The audit also found variation in presentation (words and pictures). Presentation of comprehensive, but balanced information on screening benefits and risks is complex and daunting. Issues such as framing effects, coupled with debate about screening efficacy are challenging to the design of effective information tools. The objective of increasing screening prevalence at the population level must be balanced with objectively presenting complete and clear information. Additional research is needed on how information (and mode of presentation) impact screening decisions. Public health officials need to articulate their objectives and review written communication according to important decision-making domains.

2017-01-01

Objectives Uptake of health screening is low in men, particularly among those aged <40 years. This study aimed to explore factors that influence health screening behaviour in younger men. Design This qualitative study employed an interpretive descriptive approach. Two trained researchers conducted in-depth interviews (IDIs) and focus group discussions (FGDs) using a semi-structured topic guide, which was developed based on literature review and behavioural theories. All IDIs and FGDs were audio-recorded and transcribed verbatim. Two researchers analysed the data independently using a thematic approach. Participants and setting Men working in a banking institution in Kuala Lumpur were recruited to the study. They were purposively sampled according to their ethnicity, job position, age and screening status in order to achieve maximal variation. Results Eight IDIs and five FGDs were conducted (n=31) and six themes emerged from the analysis. (1) Young men did not consider screening as part of prevention and had low risk perception. (2) The younger generation was more receptive to health screening due to their exposure to health information through the internet. (3) Health screening was not a priority in young men except for those who were married. (4) Young men had limited income and would rather invest in health insurance than screening. (5) Young men tended to follow doctors' advice when it comes to screening and preferred doctors of the same gender and ethnicity. (6) Medical overuse was also raised where young men wanted more screening tests while doctors tended to promote unnecessary screening tests to them. Conclusions This study identified important factors that influenced young men's screening behaviour. Health authorities should address young men's misperceptions, promote the importance of early detection and develop a reasonable health screening strategy for them. Appropriate measures must be put in place to reduce low value screening practices. PMID

Newborn hearing screening update for midwifery practice.

PubMed

Narrigan, D

2000-01-01

Neonatal identification of congenital hearing impairment allows interventions during the first 3 years, the critical period for language and speech development. Two recently developed biophysical testing methods offer simple, accurate, and relatively inexpensive means to identify the one to three in 1,000 healthy newborns with hearing loss. Universal screening for auditory system integrity is advocated, because almost half of all newborns with hearing impairment have no risk factors associated with this impairment. Critics of universal screening cite the high rate of false positive tests (up to 7%), which increases program costs from follow-up and re-testing large numbers of infants to ensure identifying the few affected infants. As of early 2000, 24 states had introduced some type of auditory screening program, and the U.S. Congress had passed legislation with appropriations mandating state-based auditory screening for all newborns. Midwives practicing in states already mandating biophysical screening need to comply with their local requirements; those in other states may voluntarily incorporate new auditory test methods into practice.

To identify factors associated with total sedentary time and screen time in children aged 9-11 years. For seven consecutive days, 328 children (51.5% boys) used accelerometers to monitor total sedentary time. Screen time was calculated by the self-reporting method. Individual, family, family environment, and school environment questionnaires were filled out. Body composition was measured using a Tanita scale. The mean sedentary time was 500min/day (boys: 489, girls: 511, p=0.005), and mean screen time was 234min/day (boys: 246, girls: 222, p=0.053). In both genders, factors associated with sedentary time were healthy dietary pattern and moderate-to-vigorous physical activity. In boys, only moderate-to-vigorous physical activity was significant; in girls, the healthy dietary pattern, moderate-to-vigorous physical activity, and transportation to school were significant. As for the screen time, the associated factors were body mass index and healthy dietary pattern (both genders). In boys, the associated factors were body mass index, healthy dietary pattern, and television in the bedroom. In girls, the associated factors were healthy dietary pattern, transportation to school, and physical activity policies or practice at school. Several associated factors were identified in the association between total sedentary time and screen time in children; however, only the healthy dietary pattern was common between sedentary time and screen time.

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast and cervical cancer screens to low-income, uninsured, and underinsured women. We describe the number and proportion of women eligible for cervical cancer screening services and the proportion of eligible women screened over the period 1997-2012. Low-income, uninsured, and underinsured women aged 18-64 years who have not had a hysterectomy are eligible for cervical cancer screening through the NBCCEDP. We estimated the number of low-income, uninsured women using data from the US Census Bureau. We adjusted our estimates for hysterectomy status using the National Health Interview Survey and the Behavioral Risk Factor Surveillance System. We used data from the NBCCEDP to describe the number of women receiving NBCCEDP-funded screening and calculated the proportion of eligible women who received screening through the NBCCEDP at the national level (by age group, race/ethnicity) and at the state level by age group. We used the Medical Expenditure Panel Survey to estimate the proportion of NBCCEDP-eligible women who were screened outside the NBCCEDP and the proportion that are not screened. We estimate that in 2010-2012, 705,970 women aged 18-64 years, 6.5 % (705,970 of 9.8 million) of the eligible population, received NBCCEDP-funded Pap tests. We estimate that 60.2 % of eligible women aged 18-64 years were screened outside the NBCCEDP and 33.3 % were not screened. The NBCCEDP provided 623,603 screens to women aged 40-64 years, an estimated 16.5 % of the eligible population, and 83,660 screens to women aged 18-39 years, representing an estimated 1.2 % of the eligible population. The estimated proportions of eligible women screened in each state ranged from 1.5 to 32.7 % and 5 % to 73.2 % among the 18-64 and 40-64 years age groups, respectively. Changes in the proportion of eligible women screened over the study period were nonsignificant. Although the program provided cervical

Spencer, Leslie

2002-05-01

The author collected data on serum cholesterol, blood pressure, and self-reported health behavior in 226 college students aged 18 to 26 years. Twenty-nine percent had undesirable total cholesterol levels, 10% had high cholesterol, 10% had high systolic blood pressure, and 11% had high diastolic blood pressure. Half or more of the participants consumed a diet high in saturated fats, engaged in binge drinking, had a parental risk for high cholesterol or blood pressure, or reported they experienced elevated stress levels. Men had higher risk-factor levels than women. Findings from a regression analysis revealed that smoking, binge drinking, lack of cardiovascular exercise, and eating a high saturated-fat diet were predictive of undesirable cholesterol levels. Study limitations included self-selection of participants and single measurements of blood pressure and cholesterol. Trained students served as screeners in the program for providing an effective, low-cost screening intervention.

Aim: This study was aimed to explore and describe the Kurdish women's perception of cervical cancer screening. Methods: A qualitative design based on a conventional content analysis approach. Purposive sampling was applied to 19 women chosen, who had a Pap smear or refused to have one. The study was performed in the Kurdistan Region, Iraq. Semi-structure din-depth individual interviews were carried out to collect data. Results: Four main themes including conflict, belief, and awareness about cervical cancer screening and socio-cultural factors emerged during data analysis Conclusions: Cervical cancer has a high mortality rate in the developing countries. However, only a few Kurdish women participated in the cervical cancer screening in the Kurdistan Region, Iraq. Understanding the factors associated with the women's perception of cervical cancer could guide future educational planning and clinical interventions improve the cervical cancer screening.

Genome-wide RNAi Screening to Identify Host Factors That Modulate Oncolytic Virus Therapy.

PubMed

Allan, Kristina J; Mahoney, Douglas J; Baird, Stephen D; Lefebvre, Charles A; Stojdl, David F

2018-04-03

High-throughput genome-wide RNAi (RNA interference) screening technology has been widely used for discovering host factors that impact virus replication. Here we present the application of this technology to uncovering host targets that specifically modulate the replication of Maraba virus, an oncolytic rhabdovirus, and vaccinia virus with the goal of enhancing therapy. While the protocol has been tested for use with oncolytic Maraba virus and oncolytic vaccinia virus, this approach is applicable to other oncolytic viruses and can also be utilized for identifying host targets that modulate virus replication in mammalian cells in general. This protocol describes the development and validation of an assay for high-throughput RNAi screening in mammalian cells, the key considerations and preparation steps important for conducting a primary high-throughput RNAi screen, and a step-by-step guide for conducting a primary high-throughput RNAi screen; in addition, it broadly outlines the methods for conducting secondary screen validation and tertiary validation studies. The benefit of high-throughput RNAi screening is that it allows one to catalogue, in an extensive and unbiased fashion, host factors that modulate any aspect of virus replication for which one can develop an in vitro assay such as infectivity, burst size, and cytotoxicity. It has the power to uncover biotherapeutic targets unforeseen based on current knowledge.

Radiation risks in lung cancer screening programs: a comparison with nuclear industry workers and atomic bomb survivors.

PubMed

McCunney, Robert J; Li, Jessica

2014-03-01

The National Lung Cancer Screening Trial (NLST) demonstrated that screening with low-dose CT (LDCT) scan reduced lung cancer and overall mortality by 20% and 7%, respectively. The LDCT scanning involves an approximate 2-mSv dose, whereas full-chest CT scanning, the major diagnostic study used to follow up nodules, may involve a dose of 8 mSv. Radiation associated with CT scanning and other diagnostic studies to follow up nodules may present an independent risk of lung cancer. On the basis of the NLST, we estimated the incidence and prevalence of nodules detected in screening programs. We followed the Fleischner guidelines for follow-up of nodules to assess cumulative radiation exposure over 20- and 30-year periods. We then evaluated nuclear worker cohort studies and atomic bomb survivor studies to assess the risk of lung cancer from radiation associated with long-term lung cancer screening programs. The findings indicate that a 55-year-old lung screening participant may experience a cumulative radiation exposure of up to 280 mSv over a 20-year period and 420 mSv over 30 years. These exposures exceed those of nuclear workers and atomic bomb survivors. This assessment suggests that long-term (20-30 years) LDCT screening programs are associated with nontrivial cumulative radiation doses. Current lung cancer screening protocols, if conducted over 20- to 30-year periods, can independently increase the risk of lung cancer beyond cigarette smoking as a result of cumulative radiation exposure. Radiation exposures from LDCT screening and follow-up diagnostic procedures exceed lifetime radiation exposures among nuclear power workers and atomic bomb survivors.

The aim of this investigation was to assess emergency department (ED) patients’ perceptions and preferences about an opt-in, universal, rapid HIV screening program and identify patient groups who expressed stronger beliefs about components of the testing program. From July 2005 to July 2006, ED patients in the opt-in, universal, rapid HIV screening program were interviewed in person. Multivariable regression models were used to compare participants on their beliefs about the program components. Of the 561 participants, 62.0% had previously been tested for HIV. The majority of participants (58.8%) believed the rapid and standard/conventional HIV tests to be equally accurate, 27.7% believed the rapid test to be less or much less accurate, and 8.7% believed the rapid test to be more or much more accurate. Almost two-thirds (65.1%) favored having a rapid instead of a standard/conventional HIV test, 94.6% wanted the test results within one hour, and 61.3% would be likely or very likely to undergo testing in the ED if it prolonged their ED visit. Almost all (92.5%) believed that their medical care was “not at all” delayed because of being tested, 94.1% believed that testing did “not at all” divert attention from the reason for their ED visit, and 80.9% thought that testing in the ED was “not at all” stressful. In multivariable logistic regression models, males and those with more than 12 years of formal education showed greater concerns about the rapid HIV test’s accuracy. Hispanic/Latinos, participants with governmental insurance, and those previously HIV tested were more apt to be screened for HIV even if testing delayed their ED departure. Overall, participants were highly accepting of the components of this opt-in rapid HIV screening program. However, concerns regarding the accuracy of the rapid HIV test might limit test acceptance and should be addressed during pre-test information procedures. PMID:19283644

In Tunisia, cervical cancer is considered the second leading cancer in women and causes high morbidity and mortality. This study aimed to investigate women's knowledge, attitudes, and practices of cervical cancer screening in the region of Monastir (Tunisia). We conducted a cross-sectional study exploring the cervical cancer screening knowledge, attitudes, and practices of women in the region of Monastir. The study was conducted in health centers in this region from 1st March to 30th June 2009. Data were collected using a structured questionnaire containing 15 items on demographic status, knowledge of risk factors and screening methods, and attitudes toward the relevance and effectiveness of cervical cancer screening. A total of 900 women agreed to take part in the study. Their mean age was 41.6±12.4 years and 64% did not exceed the primary level of education. According to the constructed scores, 22.8% of the participants had good knowledge of cervical cancer risk factors and 38.2% had good knowledge of screening methods. Multiple logistic regression analysis showed that women aged 45 and older, married, with good knowledge of risk factors and screening methods were more likely to undergo cervical cancer screening (P-value<0.01). This study provides useful information that could be utilized by both researchers and those involved in public health programs. The results show the need for educational programs to enhance women's adherence to cervical cancer screening programs in Tunisia. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Cervical cancer disproportionately affects women living in low- and middle-income countries. To address this global crisis, many governments and NGOs have implemented community-based screening and treatment programs at outreach camps. Here, high volumes of patients are able to access care: screening and diagnosis followed by immediate treatment of precancerous lesions onsite. However, monitoring and evaluation (M&E) of these efforts presents challenges, since each event typically relies on a different health workforce, and refers patients to different facilities for follow up and advanced care. To address these challenges, a digital imaging intervention was deployed at several screening camps in East Africa. Trained nurses screened women using a connected low-cost mobile colposcope built around a smartphone. A decision support job aid was integrated into the app controlling the device, guiding nurses and recording their diagnosis and treatment decisions. Aggregating the data from the job aid allowed M&E of the screening camp in real-time. In this paper, the M&E data from 2 different screening camps in East Africa are compared. Additionally, screening camps are compared to stationary clinics. Differences in the patient screening times, treatment rates, and individual nurse statistics were all documented through the job aid allowing for much improved epidemiological information following outreach events thus enabling targeted program improvements and provider training. Reporting data from screening camps were also shared online via public web pages, facilitating broader dissemination of health needs in specific East African communities, and sparking conversations with regional stakeholders about local disease burden.

Cervical cancer is a major health problem in South Africa. Despite having a national, population-based screening program, screening coverage is as low as 13%. Based on the role men could play in increasing cervical cancer screening and the low level of knowledge, men living in the study setting had about this health issue, we developed and pilot tested an educational program aimed at empowering men to teach their female partners and family members about cervical cancer and motivate them to be screened. The study setting was Ward 23 in Muldersdrift, a semi-urban, resource poor area situated northeast of Johannesburg. We used an intervention research design to assess the outcomes of our educational program. The primary outcome was screening uptake, with knowledge the secondary outcome. Statistics and face-to-face and telephone interviews, guided by questionnaires, were used to collect the data which were analyzed by means of descriptive statistics and content analysis. A total of 120 men (n = 120) participated in the educational program and 100 (n = 100) completed the post-test questionnaire. Only 30 women (n = 30) reported for screening. The men's knowledge improved after the education program but did not guarantee that they would educate women about cervical cancer as only 55% (n = 66) indicated they taught a female family member or their partner. Cultural restrictions were the most common reason presented for not teaching women about this health issue. Ways of supporting men to overcome cultural barriers prohibiting them from discussing matters related to sexuality should be explored, before refining and replicating the intervention.

Deficiency of mitochondrial complex I is encountered in both rare and common diseases, but we have limited therapeutic options to treat this lesion to the oxidative phosphorylation system (OXPHOS). Idebenone and menadione are redox-active molecules capable of rescuing OXPHOS activity by engaging complex I-independent pathways of entry, often referred to as “complex I bypass.” In the present study, we created a cellular model of complex I deficiency by using CRISPR genome editing to knock out Ndufa9 in mouse myoblasts, and utilized this cell line to develop a high-throughput screening platform for novel complex I bypass factors. We screened a library of ~40,000 natural product extracts and performed bioassay-guided fractionation on a subset of the top scoring hits. We isolated four plant-derived 1,4-naphthoquinone complex I bypass factors with structural similarity to menadione: chimaphilin and 3-chloro-chimaphilin from Chimaphila umbellata and dehydro-α-lapachone and dehydroiso-α-lapachone from Stereospermum euphoroides. We also tested a small number of structurally related naphthoquinones from commercial sources and identified two additional compounds with complex I bypass activity: 2-methoxy-1,4-naphthoquinone and 2-methoxy-3-methyl-1,4,-naphthoquinone. The six novel complex I bypass factors reported here expand this class of molecules and will be useful as tool compounds for investigating complex I disease biology. PMID:27622560

Since the Pap test was introduced in the 1940s, there has been an approximately 70% reduction in the incidence of squamous cell cervical cancers in many developed countries by the application of organized and opportunistic screening programs. The efficacy of the Pap test, however, is hampered by high interobserver variability and high false-negative and false-positive rates. The use of biomarkers has demonstrated the ability to overcome these issues, leading to improved positive predictive value of cervical screening results. In addition, the introduction of HPV primary screening programs will necessitate the use of a follow-up test with high specificity to triage the high number of HPV-positive tests. This paper will focus on protein biomarkers currently available for use in cervical cancer screening, which appear to improve the detection of women at greatest risk for developing cervical cancer, including Ki-67, p16INK4a, BD ProEx C, and Cytoactiv HPV L1.

This study explored Arabic, Chinese, South Asian, and Vietnamese immigrant women's experiences with a peer health educator program, a public health program that facilitated access to breast health information and mammography screening. Framed within critical social theory, this participatory action research project took place from July 2009 to January 2011. Ten focus groups and 14 individual interviews were conducted with 82 immigrant women 40 years of age and older. Qualitative methods were utilized. Thematic content analysis derived from grounded theory and other qualitative literature was employed to analyze data. Four dominant themes emerged: Breast Cancer Prevention focused on learning within the program, Social Support provided by the peer health educator and other women, Screening Services Access for Women centered on service provision, and Program Enhancements related to specific modifications required to meet the needs of immigrant women accessing the program. The findings provide insights into strategies used to promote breast health, mammography screening, and the improvement of public health programming. Perceived barriers that continue to persist are structural barriers, such as the provision of information on breast cancer and screening by family physicians. A future goal is to improve collaborations between public health and primary care to minimize this barrier.

Four dominant themes emerged: Breast Cancer Prevention focused on learning within the program, Social Support provided by the peer health educator and other women, Screening Services Access for Women centered on service provision, and Program Enhancements related to specific modifications required to meet the needs of immigrant women accessing the program. The findings provide insights into strategies used to promote breast health, mammography screening, and the improvement of public health programming. Perceived barriers that continue to persist are structural barriers, such as the provision of information on breast cancer and screening by family physicians. A future goal is to improve collaborations between public health and primary care to minimize this barrier. PMID:25810922

The objective was to describe the proportions of successful linkage to care (LTC) and identify factors associated with LTC among newly diagnosed human immunodeficiency virus (HIV)-positive patients, from two urban emergency department (ED) rapid HIV screening programs. This was a retrospective analysis of programmatic data from two established urban ED rapid HIV screening programs between November 2005 and October 2009. Trained HIV program assistants interviewed all patients tested to gather risk behavior data using a structured data collection instrument. Reactive results were confirmed by Western blot testing. Patients were provided with scheduled appointments at HIV specialty clinics at the institutions where they tested positive within 30 days of their ED visit. "Successful" LTC was defined as attendance at the HIV outpatient clinic within 30 days after HIV diagnosis, in accordance with the ED National HIV Testing Consortium metric. "Any" LTC was defined as attendance at the outpatient HIV clinic within 1 year of initial HIV diagnosis. Multivariate logistic regression was performed to determine factors associated with any LTC or successful LTC. Of the 15,640 tests administered, 108 (0.7%) were newly identified HIV-positive cases. Nearly half (47.2%) of the patients had been previously tested for HIV. Successful LTC occurred in 54% of cases; any LTC occurred in 83% of cases. In multivariate analysis, having public medical insurance and being self-pay were negatively associated with successful LTC (odds ratio [OR] = 0.33, 95% confidence interval [CI] = 0.12 to 0.96; OR = 0.34, 95% CI = 0.13 to 0.89, respectively); being female and having previously tested for HIV was negatively associated with any LTC (OR = 0.30, 95% CI = 0.10 to 0.93; OR = 0.23, 95% CI = 0.07 to 0.77, respectively). In spite of dedicated resources for arranging LTC in the ED HIV testing programs, nearly 50% of patients did not have successful LTC (i.e., LTC occurred at >30 days), although >80

Australia's National Cervical Screening Program currently recommends cytological screening every 2 years for women aged 18-69 years. Human papillomavirus (HPV) vaccination was implemented in 2007 with high population coverage, and falls in high-grade lesions in young women have been reported extensively. This decline prompted a major review of the National Cervical Screening Program and new clinical management guidelines, for which we undertook this analysis. We did effectiveness modelling and an economic assessment of potential new screening strategies, using a model of HPV transmission, vaccination, natural history, and cervical screening. First, we evaluated 132 screening strategies, including those based on cytology and primary HPV testing. Second, after a recommendation was made to adopt primary HPV screening with partial genotyping and direct referral to colposcopy of women positive for HPV16/18, we evaluated the final effect of HPV screening after incorporating new clinical guidelines for women positive for HPV. Both evaluations considered both unvaccinated and vaccinated cohorts. Strategies entailing HPV testing every 5 years and either partial genotyping for HPV16/18 or cytological co-testing were the most effective. One of the most effective and cost-effective strategies comprised primary HPV screening with referral of women positive for oncogenic HPV16/18 direct to colposcopy, with reflex cytological triage for women with other oncogenic types and direct referral for those in this group with high-grade cytological findings. After incorporating detailed clinical guidelines recommendations, this strategy is predicted to reduce cervical cancer incidence and mortality by 31% and 36%, respectively, in unvaccinated cohorts, and by 24% and 29%, respectively, in cohorts offered vaccination. Furthermore, this strategy is predicted to reduce costs by up to 19% for unvaccinated cohorts and 26% for cohorts offered vaccination, compared with the current programme

Promoting community awareness of the need for colorectal cancer screening: a pilot study.

Greenwald, Beverly

2006-01-01

The purpose of this pilot study was to determine if a community education program based on the Health Belief Model effectively promotes awareness of the need for colorectal cancer (CRC) prevention and screening. An education program was given to 20 employees of an accounting firm in a midwestern city. A survey evaluated the participants' beliefs about CRC, before and after the presentation. The results support a significant increase in the belief that CRC is preventable, and in 5 of 6 screening factors from the Health Belief Model. Participants were encouraged to share what they learned and reported that they anticipate sharing with at least 31 others. A screening questionnaire was distributed as a "cue to action" to discuss CRC screening with their physicians. Participants' intention to discuss CRC with their physicians also increased. The actual effectiveness will be evaluated with 11 participants who volunteered for a 1-year follow-up study. This community education concept had several advantages, including simultaneous access to many participants who share personal testimonials and who invite peers to become screened. The program was effective in increasing awareness of the need for CRC prevention and screening, even beyond those in attendance. The results of the 1-year follow-up study may provide more insight to what education factors promote screening most effectively.

Several countries are implementing a transition to HPV testing for cervical screening in response to the introduction of HPV vaccination and evidence indicating that HPV screening is more effective than cytology. In Australia, a 2017 transition from 2-yearly conventional cytology in 18-20 to 69 years to 5-yearly primary HPV screening in 25 to 74 years will involve partial genotyping for HPV 16/18 with direct referral to colposcopy for this higher risk group. The objective of this study was to determine the optimal management of women positive for other high-risk HPV types (not 16/18) ('OHR HPV'). We used a dynamic model of HPV transmission, vaccination, natural history and cervical screening to determine the optimal management of women positive for OHR HPV. We assumed cytology triage testing was used to inform management in this group and that those with high-grade cytology would be referred to colposcopy and those with negative cytology would receive 12-month surveillance. For those with OHR HPV and low-grade cytology (considered to be a single low-grade category in Australia incorporating ASC-US and LSIL), we evaluated (1) the 20-year risk of invasive cervical cancer assuming this group are referred for 12-month follow-up vs. colposcopy, and compared this to the risk in women with low-grade cytology under the current program (i.e. an accepted benchmark risk for 12-month follow-up in Australia); (2) the population-level impact of the whole program, assuming this group are referred to 12-month surveillance vs. colposcopy; and (3) the cost-effectiveness of immediate colposcopy compared to 12-month follow-up. Evaluation was performed both for HPV-unvaccinated cohorts and cohorts offered vaccination (coverage ~72%). The estimated 20-year risk of cervical cancer is ≤1.0% at all ages if this group are referred to colposcopy vs. ≤1.2% if followed-up in 12 months, both of which are lower than the ≤2.6% benchmark risk in women with low-grade cytology in the current

AIM: To compare high resolution colonoscopy (Olympus Lucera) with a megapixel high resolution system (Pentax HiLine) as an in-service evaluation. METHODS: Polyp detection rates and measures of performance were collected for 269 colonoscopy procedures. Five colonoscopists conducted the study over a three month period, as part of the United Kingdom bowel cancer screening program. RESULTS:There were no differences in procedure duration (χ2 P = 0.98), caecal intubation rates (χ2 P = 0.67), or depth of sedation (χ2 P = 0.64). Mild discomfort was more common in the Pentax group (χ2 P = 0.036). Adenoma detection rate was significantly higher in the Pentax group (χ2 test for trend P = 0.01). Most of the extra polyps detected were flat or sessile adenomas. CONCLUSION: Megapixel definition colonoscopes improve adenoma detection without compromising other measures of endoscope performance. Increased polyp detection rates may improve future outcomes in bowel cancer screening programs. PMID:22090787

Uptake of health screening is low in men, particularly among those aged <40 years. This study aimed to explore factors that influence health screening behaviour in younger men. This qualitative study employed an interpretive descriptive approach. Two trained researchers conducted in-depth interviews (IDIs) and focus group discussions (FGDs) using a semi-structured topic guide, which was developed based on literature review and behavioural theories. All IDIs and FGDs were audio-recorded and transcribed verbatim. Two researchers analysed the data independently using a thematic approach. Men working in a banking institution in Kuala Lumpur were recruited to the study. They were purposively sampled according to their ethnicity, job position, age and screening status in order to achieve maximal variation. Eight IDIs and five FGDs were conducted (n=31) and six themes emerged from the analysis. (1) Young men did not consider screening as part of prevention and had low risk perception. (2) The younger generation was more receptive to health screening due to their exposure to health information through the internet. (3) Health screening was not a priority in young men except for those who were married. (4) Young men had limited income and would rather invest in health insurance than screening. (5) Young men tended to follow doctors' advice when it comes to screening and preferred doctors of the same gender and ethnicity. (6) Medical overuse was also raised where young men wanted more screening tests while doctors tended to promote unnecessary screening tests to them. This study identified important factors that influenced young men's screening behaviour. Health authorities should address young men's misperceptions, promote the importance of early detection and develop a reasonable health screening strategy for them. Appropriate measures must be put in place to reduce low value screening practices. Published by the BMJ Publishing Group Limited. For permission to use (where

Colorectal cancer screening: An updated review of the available options

Issa, Iyad A; Noureddine, Malak

Colorectal cancer (CRC) is a significant cause of morbidity and mortality worldwide. However, colon cancer incidence and mortality is declining over the past decade owing to adoption of effective screening programs. Nevertheless, in some parts of the world, CRC incidence and mortality remain on the rise, likely due to factors including “westernized” diet, lifestyle, and lack of health-care infrastructure and resources. Participation and adherence to different national screening programs remain obstacles limiting the achievement of screening goals. Different modalities are available ranging from stool based tests to radiology and endoscopy with varying sensitivity and specificity. However, the availability of these tests is limited to areas with high economic resources. Recently, FDA approved a blood-based test (Epi procolon®) for CRC screening. This blood based test may serve to increase the participation and adherence rates. Hence, leading to increase in colon cancer detection and prevention. This article will discuss various CRC screening tests with a particular focus on the data regarding the new approved blood test. Finally, we will propose an algorithm for a simple cost-effective CRC screening program. PMID:28811705

Importance Diabetic retinopathy (DR) is the leading cause of blindness in adults of working age in the United States. In the Los Angeles County safety net, a nonvertically integrated system serving underinsured and uninsured patients, the prevalence of DR is approximately 50%, and owing to limited specialty care resources, the average wait times for screening for DR have been 8 months or more. Objective To determine whether a primary care–based teleretinal DR screening (TDRS) program reduces wait times for screening and improves timeliness of needed care in the Los Angeles County safety net. Design, Setting, and Participants Quasi-experimental, pretest-posttest evaluation of exposure to primary care–based TDRS at 5 of 15 Los Angeles County Department of Health Services safety net clinics from September 1, 2013, to December 31, 2015, with a subgroup analysis of random samples of 600 patients before and after the intervention (1200 total). Exposure Primary care clinic–based teleretinal screening for DR. Main Outcomes and Measures Annual rates of screening for DR before and after implementation of the TDRS program across the 5 clinics, time to screening for DR in a random sample of patients from these clinics, and a description of the larger framework of program implementation. Results Among the 21 222 patients who underwent the screening (12 790 female, 8084 male, and 348 other gender or not specified; mean [SD] age, 57.4 [9.6] years), the median time to screening for DR decreased from 158 days (interquartile range, 68-324 days) before the intervention to 17 days (interquartile range, 8-50 days) after initiation of the program (P < .001). Overall annual screening rates for DR increased from 5942 of 14 633 patients (40.6%) before implementation to 7470 of 13 133 patients (56.9%) after initiation of the program at all 15 targeted clinics (odds ratio, 1.9; 95% CI, 1.3-2.9; P = .002). Of the 21 222 patients who were screened, 14 595 (68.8%) did

Abstract Background Depression is a prevalent, yet underdiagnosed, psychiatric disorder among patients with end-stage renal disease. Active case identification through routine screening is suggested; however, patient-related barriers may reduce the effectiveness of screening for, and treating, depression. This study aimed to explore the perceived barriers that limit patients from participating in screening and treatment programs for depression. Methods In a cross-sectional study of chronic maintenance hemodialysis patients, the Perceived Barriers to Psychological Treatment questionnaire, adapted to include screening, was used to measure perceived barriers. The two-item Patient Health Questionnaire was used to identify patients with depressive symptoms. Results Of 160 participants, 73.1% reported at least one barrier preventing them from participation [95% confidence interval (95% CI) 66.2–80.0%]. Patients with depressive symptoms were more likely to perceive at least one barrier to a screening program for depression compared with those without depressive symptoms (96% versus 68.9%, respectively; odds ratio = 10.8; 95% CI 1.4–82.8; P = 0.005). The association of the barrier scores with depressive symptoms remained significant after adjustment for patient’s characteristics. The most common barriers that patients expressed were concerns about the side effects of any antidepressant medications that may be prescribed (40%), concerns about having more medications (32%), feeling that the problem is not severe enough (23%) and perceiving no risk of depression (23%). Conclusions Negative perceptions about depression and its treatment among hemodialysis patients constitute an important barrier to identifying this condition and first need to be addressed before implementing a screening program in this population.

In Malaysia, colorectal cancer is the most common cancer in males and the third most common in females. Mortality due to colorectal cancer can be effectively reduced with early diagnosis. This study was designed to look into colorectal cancer screening participation and its barriers among average risk individuals in Malaysia. A cross sectional study was conducted from August 2009 till April 2010 involving average risk individuals from 44 primary care clinics in West Malaysia. Each individual was asked whether they have performed any of the colorectal cancer screening methods in the past five years. The barrier questions had three domains: patient factors, test factors and health care provider factors. Descriptive analysis was achieved using Statistical Program for Social Sciences (SPSS) version 12.0. A total of 1,905 average risk individuals responded making a response rate of 93.8%. Only 13 (0.7%) respondents had undergone any of the colorectal cancer screening methods in the past five years. The main patient and test factors for not participating were embarrassment (35.2%) and feeling uncomfortable (30.0%), respectively. There were 11.2% of respondents who never received any advice to do screening. The main reason for them to undergo screening was being advised by health care providers (84.6%). The study showed that participation in colorectal cancer screening in Malaysia is extremely low and multiple factors contribute to this situation. Given the importance of the disease, efforts should be made to increase colorectal cancer screening activities in Malaysia.

To review and classify the interval cancers found in the Principality of Asturias's Breast Cancer Screening Program (PDPCM). A secondary objective was to determine the histological characteristics, size, and stage of the interval cancers at the time of diagnosis. We included the interval cancers in the PDPCM in the period 2003-2007. Interval cancers were classified according to the breast cancer screening program protocol, with double reading without consensus, without blinding, with arbitration. Mammograms were interpreted by 10 radiologists in the PDPCM. A total of 33.7% of the interval cancers could not be classified; of the interval cancers that could be classified, 40.67% were labeled true interval cancers, 31.4% were labeled false negatives on screening, 23.7% had minimal signs, and 4.23% were considered occult. A total of 70% of the interval cancers were diagnosed in the year of the period between screening examinations and 71.7% were diagnosed after subsequent screening. A total of 76.9% were invasive ductal carcinomas, 61.1% were stage II when detected, and 78.7% were larger than 10mm when detected. The rate of interval cancers and the rate of false negatives in the PDPCM are higher than those recommended in the European guidelines. Interval cancers are diagnosed later than the tumors detected at screening. Studying interval cancers provides significant training for the radiologists in the PDPCM. Copyright © 2011 SERAM.

To assess the budgetary impact of switching from screen-film mammography to full-field digital mammography in a population-based breast cancer screening program. A discrete-event simulation model was built to reproduce the breast cancer screening process (biennial mammographic screening of women aged 50 to 69 years) combined with the natural history of breast cancer. The simulation started with 100,000 women and, during a 20-year simulation horizon, new women were dynamically entered according to the aging of the Spanish population. Data on screening were obtained from Spanish breast cancer screening programs. Data on the natural history of breast cancer were based on US data adapted to our population. A budget impact analysis comparing digital with screen-film screening mammography was performed in a sample of 2,000 simulation runs. A sensitivity analysis was performed for crucial screening-related parameters. Distinct scenarios for recall and detection rates were compared. Statistically significant savings were found for overall costs, treatment costs and the costs of additional tests in the long term. The overall cost saving was 1,115,857€ (95%CI from 932,147 to 1,299,567) in the 10th year and 2,866,124€ (95%CI from 2,492,610 to 3,239,638) in the 20th year, representing 4.5% and 8.1% of the overall cost associated with screen-film mammography. The sensitivity analysis showed net savings in the long term. Switching to digital mammography in a population-based breast cancer screening program saves long-term budget expense, in addition to providing technical advantages. Our results were consistent across distinct scenarios representing the different results obtained in European breast cancer screening programs.
