    The University of the District of Columbia (UDC) and the Lombardi Comprehensive Cancer Center (LCCC), Georgetown University Medical Center established a Masters Degree Program in Cancer Biology, Prevention and Control at UDC that is jointly administered and taught by UDC and LCCC faculty. The goal of the Masters Degree Program is to educate students as master-level cancer professionals capable of conducting research and service in cancer biology, prevention, and control or to further advance the education of students to pursue doctoral studies. The Program's unique nature is reflected in its philosophy "the best cancer prevention and control researchers are those with a sound understanding of cancer biology". This program is a full-time, 2-year, 36-credit degree in which students take half of their coursework at UDC and half of their coursework at LCCC. During the second year, students are required to conduct research either at LCCC or UDC. Unlike most cancer biology programs, this unique Program emphasizes both cancer biology and cancer outreach training.

    This article provides the findings of a survey of previous and current students in the UDC/GU-LCCC master's degree program. This master's degree program, Cancer Biology, Prevention, and Control is administered and taught jointly by faculty of a Minority Serving Institution, the University of the District of Columbia, and the Lombardi Comprehensive Cancer Center to incorporate the strengths of a community-based school with a research intensive medical center. The program was initiated in 2008 through agreements with both University administrations and funding from the National Cancer Institute. The master's degree program is 36 credits with a focus on coursework in biostatistics, epidemiology, tumor biology, cancer prevention, medical ethics, and cancer outreach program design. For two semesters during the second year, students work full-time with a faculty person on a laboratory or outreach project that is a requirement for graduation. Students are supported and encouraged to transition to a doctoral degree after they obtain the master's and many of them are currently in doctorate programs. Since the inception of the program, 45 students have initiated the course of study, 28 have completed the program, and 13 are currently enrolled in the program. The survey was designed to track the students in their current activities, as well as determine which courses, program enhancements, and research experiences were the least and most useful, and to discern students' perceptions of knowledge acquired on various aspects of Cancer Biology Prevention, and Control Master's Program. Thirty of the 35 individuals to whom email requests were sent responded to the survey, for a response rate of 85.7%. The results of this study will inform the strengthening of the Cancer Biology program by the Education Advisory Committee. They can also be used in the development of comparable collaborative master's degree programs designed to address the significant disparities in prevalence of

    Cancer is predicted to be an increasingly important cause of morbidity and mortality in Bangladesh in the next few decades. The estimated incidence of 12.7 million new cancer cases will rise to 21.4 million by 2030. More than two-thirds of the total expenditure on health is through out-of-pocket payments. According to the Bangladesh Bureau of Statistics, cancer is the sixth leading cause of death. International Agency for Research on Cancer has estimated cancer-related death rates in Bangladesh to be 7.5% in 2005 and 13% in 2030. The two leading causes are in males are lung and oral cancer and in females are breast cancer and cervical cancer. Bangladesh is now in severe shortage of radiation therapy machines, hospital bed, trained oncologists, medical radiation physicists and technologists. Bangladesh having different cancers associated with smoking and smokeless tobacco use, Human papilloma virus infection, Hepatitis B and C infection, Helicobacter Pylori infection, arsenic contaminated groundwater, availability of chemical carcinogens mainly formalin treated fruits, fish and vegetables at open market, tannery waste contaminated with chromium (which is used for poultry feed and fish feed preparation). A World Health Organization study revealed the annual cost of illnesses in Bangladesh attributable to tobacco usage is US$ 500 million and the total annual benefit from the tobacco sector is US$ 305 million as tax revenue. Bangladesh has developed a National Cancer Control Strategy and Action Plan with the aim of delivering a universal, quality-based and timely service. Cancer prevention through tobacco control, health promotion and vaccination program, cancer early detection program for oral cavity, breast and cervix has initiated. Cancer detection and diagnostic facilities will be made available at medical colleges and district- hospitals and establish a referral chain. National capacity development, more cancer research will allow Bangladesh to deal effectively

    Full Text Available Abstract Background Cancer-related fatigue (CRF and its impact on patients' quality of life has been an increasing subject of research. However, in Germany there is a lack of evidence-based interventions consistent with the multidimensional character of fatigue. The objective of this study is to develop and evaluate a self-management program for disease-free cancer patients to cope with CRF. Methods Based on evidence extracted from a literature review, a curriculum for the self-management program was elaborated. The curriculum was reviewed and validated by an interdisciplinary expert group and the training-modules will be pretested with a small number of participants and discussed in terms of feasibility and acceptance. To determine the efficacy of the program a randomised controlled trial will be carried out: 300 patients will be recruited from oncological practices in Bremen, Germany, and will be allocated to intervention or control group. The intervention group participates in the program, whereas the control group receives standard care and the opportunity to take part in the program after the end of the follow-up (waiting control group. Primary outcome measure is the level of fatigue, secondary outcome measures are quality of life, depression, anxiety, self-efficacy and physical activity. Data will be collected before randomisation, after intervention, and after a follow-up of 6 months. Discussion Because there are no comparable self-management programs for cancer survivors with fatigue, the development of the curriculum has been complex; therefore, the critical appraisal by the experts was an important step to validate the program and their contributions have been integrated into the curriculum. The experts appreciated the program as filling a gap in outpatient cancer care. If the results of the evaluation prove to be satisfactory, the outpatient care of cancer patients can be broadened and supplemented. Trial Registration Clinical

  7. Widespread FRA1-dependent control of mesenchymal transdifferentiation programs in colorectal cancer cells.

    Directory of Open Access Journals (Sweden)

    Jeannine Diesch

    Full Text Available Tumor invasion and metastasis involves complex remodeling of gene expression programs governing epithelial homeostasis. Mutational activation of the RAS-ERK is a frequent occurrence in many cancers and has been shown to drive overexpression of the AP-1 family transcription factor FRA1, a potent regulator of migration and invasion in a variety of tumor cell types. However, the nature of FRA1 transcriptional targets and the molecular pathways through which they promote tumor progression remain poorly understood. We found that FRA1 was strongly expressed in tumor cells at the invasive front of human colorectal cancers (CRCs, and that its depletion suppressed mesenchymal-like features in CRC cells in vitro. Genome-wide analysis of FRA1 chromatin occupancy and transcriptional regulation identified epithelial-mesenchymal transition (EMT-related genes as a major class of direct FRA1 targets in CRC cells. Expression of the pro-mesenchymal subset of these genes predicted adverse outcomes in CRC patients, and involved FRA-1-dependent regulation and cooperation with TGFβ signaling pathway. Our findings reveal an unexpectedly widespread and direct role for FRA1 in control of epithelial-mesenchymal plasticity in CRC cells, and suggest that FRA1 plays an important role in mediating cross talk between oncogenic RAS-ERK and TGFβ signaling networks during tumor progression.

    Geographic information systems (GIS) mapping technologies have potential to advance public health promotion by mapping regional differences in attributes (e.g., disease burden, environmental exposures, access to health care services) to suggest priorities for public health interventions. Training in GIS for comprehensive cancer control (CCC) has been overlooked. State CCC programs' GIS training needs were assessed by interviewing 49 state CCC directors. A majority perceived a need for GIS training, slightly more than half of state CCC programs had access to geocoded data, and the majority of programs did not require continuing education credits of their staff. CCC directors perceived judging maps and realizing their limitations as important skills and identified epidemiologists, CCC staff, public health officials, policy makers, and cancer coalition members as training audiences. They preferred in-class training sessions that last a few hours to a day. Lessons learned are shared to develop training programs with translatable GIS skills for CCC.

    The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) has played a critical role in providing cancer screening services to American Indian and Alaska Native (AI/ANs) women and strengthening tribal screening capacity. Since 1991, the NBCCEDP has funded states, tribal nations, and tribal organizations to develop and implement organized screening programs. The ultimate goal is to deliver breast and cervical cancer screening to women who do not have health insurance and cannot afford to pay for these services. The delivery of clinical services is supported through complementary program efforts such as professional development, public education and outreach, and patient navigation. This article seeks to describe the growth of NBCCEDP's tribal commitment and the unique history and aspects of serving the AI/AN population. The article describes: 1) how this program has demonstrated success in improving screening of AI/AN women; 2) innovative partnerships with the Indian Health Service, state programs, and other organizations that have improved tribal public health infrastructure; and 3) the evolution of Centers for Disease Control and Prevention work with tribal communities.

    Full Text Available Abstract Background Elevated stress can exacerbate cancer symptom severity, and after completion of primary cancer treatments, many individuals continue to have significant distress. Mindfulness-Based Cancer Recovery (MBCR is an 8-week group psychosocial intervention consisting of training in mindfulness meditation and yoga designed to mitigate stress, pain, and chronic illness. Efficacy research shows face-to-face (F2F MBCR programs have positive benefits for cancer patients; however barriers exist that impede participation in F2F groups. While online MBCR groups are available to the public, none have been evaluated. Primary objective: determine whether underserved patients are willing to participate in and complete an online MBCR program. Secondary objectives: determine whether online MBCR will mirror previous efficacy findings from F2F MBCR groups on patient-reported outcomes. Method/design The study includes cancer patients in Alberta, exhibiting moderate distress, who do not have access to F2F MBCR. Participants will be randomized to either online MBCR, or waiting for the next available group. An anticipated sample size of 64 participants will complete measures online pre and post treatment or waiting period. Feasibility will be tracked through monitoring numbers eligible and participating through each stage of the protocol. Discussion 47 have completed/completing the intervention. Data suggest it is possible to conduct a randomized waitlist controlled trial of online MBCR to reach underserved cancer survivors. Trial registration Clinical Trials.gov Identifier: NCT01476891

    Widespread use of the human papillomavirus (HPV) vaccine has the potential to reduce incidence from HPV-associated cancers. However, vaccine uptake among adolescents remains well below the Healthy People 2020 targets. The Centers for Disease Control and Prevention (CDC) National Comprehensive Cancer Control Program (NCCCP) awardees are well positioned to work with immunization programs to increase vaccine uptake. The CDC chronic disease management information system was queried for objectives and activities associated with HPV vaccine that were reported by NCCCP awardees from 2013 to 2016 as part of program reporting requirements. A content analysis was conducted on the query results to categorize interventions according to strategies outlined in The Guide to Community Preventive Services and the 2014 President's Cancer Panel report. Sixty-two percent of NCCCP awardees had planned or implemented at least one activity since 2013 to address low HPV vaccination coverage in their jurisdictions. Most NCCCP awardees (86%) reported community education activities, while 65% reported activities associated with provider education. Systems-based strategies such as client reminders or provider assessment and feedback were each reported by less than 25% of NCCCP awardees. Many NCCCP awardees report planning or implementing activities to address low HPV vaccination coverage, often in conjunction with state immunization programs. NCCCP awardees can play a role in increasing HPV vaccination coverage through their cancer prevention and control expertise and access to partners in the healthcare community.

    Full Text Available Abstract Background Despite evidence that physical activity improves the health and well-being of prostate cancer survivors, many men do not engage in sufficient levels of activity. The primary aim of this study (ENGAGE is to determine the efficacy of a referral and physical activity program among survivors of prostate cancer, in terms of increasing participation in physical activity. Secondary aims are to determine the effects of the physical activity program on psychological well-being, quality of life and objective physical functioning. The influence of individual and environmental mediators on participation in physical activity will also be determined. Methods/Design This study is a cluster randomised controlled trial. Clinicians of prostate cancer survivors will be randomised into either the intervention or control condition. Clinicians in the intervention condition will refer eligible patients (n = 110 to participate in an exercise program, comprising 12 weeks of supervised exercise sessions and unsupervised physical activity. Clinicians allocated to the control condition will provide usual care to eligible patients (n = 110, which does not involve the recommendation of the physical activity program. Participants will be assessed at baseline, 12 weeks, 6 months, and 12 months on physical activity, quality of life, anxiety, depression, self-efficacy, outcome expectations, goals, and socio-structural factors. Discussion The findings of this study have implications for clinicians and patients with different cancer types or other chronic health conditions. It will contribute to our understanding on the potential impact of clinicians promoting physical activity to patients and the long term health benefits of participating in physical activity programs.

    The goal of cancer control research is "to generate basic knowledge about how to monitor and change individual and collective behavior and to ensure that knowledge is translated into practice and policy rapidly, effectively, and efficiently" (Division of Cancer Control and Population Sciences in Cancer control framework and synthese rationale, 2010). Research activities span the cancer control continuum from prevention to early detection and diagnosis through treatment and survivorship (Division of Cancer Control and Population Sciences in Cancer control framework and synthese rationale, 2010). While significant advancements have been made in understanding, preventing and treating cancer in the past few decades, these benefits have yielded disproportionate results in cancer morbidity and mortality across various socioeconomic and racial/ethnic subgroups (Ozols et al in J Clin Oncol, 25(1):146-1622, 2007). It has been a high priority since the beginning of the Comprehensive Cancer Control (CCC) movement to utilize research in the development and implementation of cancer plans in the states, tribes and tribal organizations, territories and US Pacific Island Jurisdictions. Nevertheless, dissemination and implementation of research in coalition activities has been challenging for many programs. Lessons learned from programs and coalitions in the implementation and evaluation of CCC activities, as well as resources provided by national partners, can assist coalitions with the translation of research into practice.

    The solution of the optimal control problem, even with low order dynamical systems, can usually strain the analytical ability of most engineers. The understanding of this subject matter, therefore, would be greatly enhanced if a software package existed that could simulate simple generic problems. Surprisingly, despite a great abundance of commercially available control software, few, if any, address the part of optimal control in its most generic form. The purpose of this paper is, therefore, to present a simple computer program that will perform simulations of optimal control problems that arise from the first necessary condition and the Pontryagin's maximum principle.

    Excess body weight at diagnosis and weight gain after breast cancer are associated with poorer long-term prognosis. This study investigated the effects of a lifestyle intervention on body weight and other health outcomes influencing long-term prognosis in overweight women (BMI > 25.0 kg/m(2)) recovering from early-stage (stage I-III) breast cancer. A total of 90 women treated 3-18 months previously were randomly allocated to a 6-month exercise and hypocaloric healthy eating program (n = 47, aged 55.6 ± 10.2 year) or control group (n = 43, aged 55.9 ± 8.9 year). Women in the intervention group received three supervised exercise sessions per week and individualized dietary advice, supplemented by weekly nutrition seminars. Body weight, waist circumference, waist/hip ratio [WHR], cardiorespiratory fitness, blood biomarkers associated with breast cancer recurrence and cardiovascular disease risk, and quality of life (FACT-B) were assessed at baseline and 6 months. Three-day diet diaries were used to assess macronutrient and energy intakes.

  7. Development of a Federally Funded Demonstration Colorectal Cancer Screening Program

    Directory of Open Access Journals (Sweden)

    2008-04-01

    Full Text Available Colorectal cancer is the second leading cause of cancer-related mortality among U.S. adults. In 2004, treatment costs for colorectal cancer were $8.4 billion.There is substantial evidence that colorectal cancer incidence and mortality are reduced with regular screening. The natural history of this disease is also well described: most colorectal cancers develop slowly from preexisting polyps. This slow development provides an opportunity to intervene with screening tests, which can either prevent colorectal cancer through the removal of polyps or detect it at an early stage. However, much less is known about how best to implement an effective colorectal cancer screening program. Screening rates are low, and uninsured persons, low-income persons, and persons who have not visited a physician within a year are least likely to be screened.Although the Centers for Disease Control and Prevention (CDC has 15 years of experience supporting the National Breast and Cervical Cancer Early Detection Program for the underserved population, a similar national program for colorectal cancer is not in place. To explore the feasibility of implementing a national program for the underserved U.S. population and to learn which settings and which program models are most viable and cost-effective, CDC began a 3-year colorectal cancer screening demonstration program in 2005.This article describes briefly this demonstration program and the process CDC used to design it and to select program sites. The multiple-methods evaluation now under way to assess the program’s feasibility and describe key outcomes is also detailed. Evaluation results will be used to inform future activities related to organized screening for colorectal cancer.

    Three federal programs with the potential to reduce cervical cancer incidence, morbidity, and mortality, especially among underserved populations, are administered by the Centers for Disease Control and Prevention (CDC): the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), the Vaccines for Children (VFC) Program, and the Section 317 immunization grant program. The NBCCEDP provides breast and cervical cancer screening and diagnostic services to uninsured and underinsured women. The VFC program and the Section 317 immunization grant program provide vaccines, including human papillomavirus (HPV) vaccine, to targeted populations at no cost for these vaccines. This article describes the programs, their histories, populations served, services offered, and roles in preventing cervical cancer through HPV vaccination and cervical cancer screening. Potential long-term reduction in healthcare costs resulting from HPV vaccination is also discussed. As an example of an initiative to vaccinate uninsured women aged 19-26 years through a cancer services program, a state-based effort that was recently launched in New York, is highlighted.

  13. Perspective on BVDV control programs.

    Science.gov (United States)

    Givens, M Daniel; Newcomer, Benjamin W

    2015-06-01

    Programs for control and eradication of bovine viral diarrhea virus (BVDV) are often considered prudent when the expense of a control program within a specified time frame effectively prevents loss due to disease and the expense of control does not exceed the costs associated with infection. In some geographic areas, concerns about animal welfare or desires to reduce antibiotic usage may motivate BVDV control even when control programs are associated with a lack of financial return on investment. In other geographic areas, concerns about financial return on investment may be the key motivating factor in considering implementation of BVDV control programs. Past experiences indicate that systematic, well-coordinated control programs have a clear potential for success, while voluntary control programs in cultures of distributed decision-making often result in notable initial progress that ultimately ends in dissolution of efforts. Segmentation of the cattle industry into cow-calf producers, stocker/backgrounders, and feedlot operators amplifies the distribution of decision-making regarding control programs and may result in control measures for one industry segment that are associated with significant costs and limited rewards. Though the host range of BVDV extends well beyond cattle, multiple eradication programs that focus only on testing and removal of persistently infected (PI) cattle have proven to be effective in various countries. While some individuals consider education of producers to be sufficient to stimulate eradication of BVDV, research surrounding the adoption of innovative health care procedures suggests that the process of adopting BVDV control programs has a social element. Collegial interactions and discussions may be crucial in facilitating the systematic implementation necessary to optimize the long-term success of control programs. Compulsory control programs may be considered efficient and effective in some regions; however, in a nation where

    Full Text Available IntroductionIn 2005, the Centers for Disease Control and Prevention funded five sites to implement the Colorectal Cancer Screening Demonstration Program (CRCSDP. An evaluation is being conducted that includes a multiple case study. Case study results for the start-up period, the time between initial funding and screening initiation, provide details about the program models and start-up process and reveal important lessons learned.MethodsThe multiple case study includes all five CRCSDP sites, each representing a unique case. Data were collected from August 2005 through September 2006 from documents, observations, and more than 70 interviews with program staff and stakeholders.ResultsSites differed by geographic service area, screening modality selected, and service delivery structure. Program models were influenced by two factors: preexisting infrastructure and the need to adapt programs to fit local service delivery structures. Several sites modeled program components after their National Breast and Cervical Cancer Early Detection Program. Medical advisory boards convened by all sites provided clinical support for developing program policies and quality assurance plans. Partnerships with comprehensive cancer control programs facilitated access to financial and in-kind resources.ConclusionThe program models developed by the CRCSDP sites offer a range of prototypes. Case study results suggest benefits in employing a multidisciplinary staff team, assembling a medical advisory board, collaborating with local partners, using preexisting resources, designing programs that are easily incorporated into existing service delivery systems, and planning for adequate start-up time.

    . For colorectal cancer, the stage at diagnosis of cases diagnosed in northeast Pennsylvania was compared to data from prior years. A population-based interview study of healthy adults was conducted to document the status of cancer screening and to estimate the prevalence of established cancer risk factors in this community. This study is similar in design to that used by the Centers for Disease Control and Prevention’s (CDC) Behavioral Risk Factor Surveillance System (BRFSS). EXPERIMENTAL METHODS AND PROCEDURES: This program includes two distinct but related projects. The first project uses existing data to conduct cancer surveillance in northeast Pennsylvania, and the second is a population-based study of cancer risk factors and cancer screening behaviors in this same population. HUMAN SUBJECTS CONSIDERATIONS This program includes two projects: cancer surveillance and a population-based study of cancer risk factors and screening behavior. The cancer surveillance project involves only the use of existing aggregate data or de-identified data. As such, the surveillance project is exempt from human subjects considerations. The study of cancer risk factors and screening behaviors includes data from a random sample of adult residents of northeast Pennsylvania who are 18 or more years of age. All races, ethnicities and both sexes are included in proportion to their representation in the population. Subjects are interviewed anonymously by telephone; those who are unable to complete an interview in English are ineligible. This project has been reviewed and approved by the Scranton-Temple Residency Program IRB (IRB00001355), which is the IRB for the Northeast Regional Cancer Institute.

    Each state is autonomous in its comprehensive cancer control (CCC) program, and considerable heterogeneity exists in the program plans. However, researchers often focus on the concept of nationally representative data and pool observations across states using regression analysis to come up with average effects when interpreting results. Due to considerable state autonomy and heterogeneity in various dimensions-including culture, politics, historical precedent, regulatory environment, and CCC efforts-it is important to examine states separately and to use geographic analysis to translate findings in place and time. We used 100 percent population data for Medicare-insured persons aged 65 or older and examined predictors of breast cancer (BC) and colorectal cancer (CRC) screening from 2001-2005. Examining BC and CRC screening behavior separately in each state, we performed 100 multilevel regressions. We summarize the state-specific findings of racial disparities in screening for either cancer in a single bivariate map of the 50 states, producing a separate map for African American and for Hispanic disparities in each state relative to whites. The maps serve to spatially translate the voluminous regression findings regarding statistically significant disparities between whites and minorities in cancer screening within states. Qualitative comparisons can be made of the states' disparity environments or for a state against a national benchmark using the bivariate maps. We find that African Americans in Michigan and Hispanics in New Jersey are significantly more likely than whites to utilize CRC screening and that Hispanics in 6 states are significantly and persistently more likely to utilize mammography than whites. We stress the importance of spatial translation research for informing and evaluating CCC activities within states and over time.

    We describe Salmonella control programs of broiler chickens, layer hens, and pigs in Denmark. Major reductions in the incidence of foodborne human salmonellosis have occurred by integrated control of farms and food processing plants. Disease control has been achieved by monitoring the herds and flocks, eliminating infected animals, and diversifying animals (animals and products are processed differently depending on Salmonella status) and animal food products according to the determined risk. In 2001, the Danish society saved U.S.$25.5 million by controlling Salmonella. The total annual Salmonella control costs in year 2001 were U.S.$14.1 million (U.S.$0.075/kg of pork and U.S.$0.02/kg of broiler or egg). These costs are paid almost exclusively by the industry. The control principles described are applicable to most industrialized countries with modern intensive farming systems.

    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.

    2010-11-01

    Full Text Available Abstract Background Childhood cancer and its treatment have considerable impact on a child's physical and mental wellbeing. Especially long-term administration of chemotherapy and/or radiotherapy impairs physical fitness both during and after therapy, when children often present with muscle weakness and/or low cardiorespiratory fitness. Physical exercise can improve these two elements of physical fitness, but the positive effects of physical exercise might be further increased when a child's wellbeing is simultaneously enhanced by psychosocial training. Feeling better may increase the willingness and motivation to engage in sports activities. Therefore, this multi-centre study evaluates the short and long-term changes in physical fitness of a child with a childhood malignancy, using a combined physical exercise and psychosocial intervention program, implemented during or shortly after treatment. Also examined is whether positive effects on physical fitness reduce inactivity-related adverse health problems, improve quality of life, and are cost-effective. Methods This multi-centre randomized controlled trial compares a combined physical and psychosocial intervention program for children with cancer, with care as usual (controls. Children with cancer (aged 8-18 years treated with chemotherapy and/or radiotherapy, and who are no longer than 1 year post-treatment, are eligible for participation. A total of 100 children are being recruited from the paediatric oncology/haematology departments of three Dutch university medical centres. Patients are stratified according to pubertal stage (girls: age ≤10 or >10 years; boys: ≤11 or >11 years, type of malignancy (haematological or solid tumour, and moment of inclusion into the study (during or after treatment, and are randomly assigned to the intervention or control group.

    The objective of the Advanced Emissions Control Development Program (AECDP) is to develop practical, cost-effective strategies for reducing the emissions of air toxics from coal-fired boilers. Ideally, the project aim is to effectively control air toxic emissions through the use of conventional flue gas cleanup equipment such as electrostatic precipitators (ESPS), fabric filters (baghouse), and wet flue gas desulfurization. Development work to date has concentrated on the capture of mercury, other trace metals, fine particulate and hydrogen chloride. Following the construction and evaluation of a representative air toxics test facility in Phase I, Phase II focused on the evaluation of mercury and several other air toxics emissions. The AECDP is jointly funded by the United States Department of Energy's Federal Energy Technology Center (DOE), the Ohio Coal Development Office within the Ohio Department of Development (oCDO), and Babcock& Wilcox-a McDermott company (B&W).

  12. Stewardship and cancer screening programs in Italy

    2011-06-01

    Full Text Available As one of the four major functions of health systems, Stewardship is on the health agenda of several countries worldwide. There is, however, little empirical evidence to support or guide its implementation. To help bridge this gap, the paper aims to contribute to the empirical evidence for health system stewardship and, importantly, to offer implementers an explanatory example of what it could mean in practice. It achieves this by analyzing the experience of the Italian Cancer Screening Programs (from 2004-2009 within a comprehensive framework for health system stewardship. The analysis is largely based on primary and secondary qualitative data, using information collected from an in-depth interview, official documents, and scientific and grey literature. We describe the framework and sub-functions of stewardship, identify the stewardship activities that were carried out by the Programs, and reflect upon the operability of the framework as well as the activities that the Programs have not implemented but would benefit from doing so. The general experience and activities of the Italian Cancer Screening Programs fit well into the stewardship framework, despite not having followed it a priori. Overall, the Programs managed to implement most activities under each sub-function. As an empirical case study, they corroborated the theoretical framework and demonstrated how it could be translated into certain activities on an operational platform. Ultimately, the analysis showed that the framework of stewardship is useful for structuring and prioritizing the most important activities of a steward and, thus, provides a good benchmark for implementers.

    Surgery and radiotherapy commonly cause adverse musculoskeletal problems, particularly loss of strength and range of motion, in the upper quadrant of breast cancer patients. Few well-designed studies have investigated whether these impairments can be prevented. Stretching is an effective technique for increasing range of motion, hence the aim of this study was to investigate whether a stretching program reduced acute musculoskeletal impairments in patients undergoing radiotherapy for breast cancer. Sixty-four women were recruited prior to commencement of radiotherapy following breast cancer surgery. Participants were randomised to either a control or stretch group. Participants in both groups were reviewed by the physical therapist on a weekly basis for approximately 6 weeks, and were given general information about skin care and lymphedema. The control group received no advice about exercise. The stretch group received instruction on low-load, prolonged pectoral stretches, which were to be performed daily and were checked at weekly visits. Shoulder range of motion, strength, arm circumference, and quality of life measurements were taken prior to, and at completion of radiotherapy, and at 7 months after radiotherapy. There was no difference in any outcome between groups. Breast symptoms increased for both groups during radiotherapy, without loss of strength or range of movement. The incidence of lymphedema during the study was low for both groups and did not differ between groups. The pectoral stretching program did not influence the outcomes measured because the symptoms reported by patients were not a consequence of contracture.

  17. The National Program of Cancer Registries: Explaining State Variations in Average Cost per Case Reported

    Directory of Open Access Journals (Sweden)

    Hannah K. Weir, PhD

    2005-07-01

    Full Text Available Introduction The Centers for Disease Control and Prevention’s National Program of Cancer Registries is a federally funded surveillance program that provides support and assistance to state and territorial health departments for the operation of cancer registries. The objective of this study was to identify factors associated with the Centers for Disease Control and Prevention’s costs to report cancer cases during the first 5 years of the National Program of Cancer Registries. Methods Information on expenditures and number of cases reported through the National Program of Cancer Registries was used to estimate the average cost per case reported for each state program. Additional information was obtained from other sources, and regression analyses were used to assess the contribution of each factor. Results Average costs of the National Program of Cancer Registries differed substantially among programs and were inversely associated with the number of cases reported (P < .001. The geographic area of the state was positively associated with the cost (P = .01, as was the regional cost of living (P = .08, whereas the program type (i.e., enhancement or planning was inversely associated with cost (P = .08. Conclusion The apparent existence of economies of scale suggests that contiguous state programs might benefit from sharing infrastructure and other fixed costs, such as database management resources, depending on the geographic area and population size served. Sharing database management resources might also promote uniform data collection and quality control practices, reduce the information-sharing burden among states, and allow more resources to be used for other cancer prevention and control activities.

    Environmental Restoration managers need to demonstrate that their programs are under control. Unlike most industrial programs, the public is heavily involved in Environmental Restoration activities. The public is demanding that the country prove that real progress is being made towards cleaning up the environment. A Program Control Management System can fill this need. It provides a structure for planning, work authorization, data accumulation, data analysis and change control. But it takes time to implement a control system and the public is losing its patience. This paper describes critical items essential to the quick development and implementation of a successful control system.

    This article describes a cancer survivorship program that addressed quality of life (QOL) changes related to chemotherapy. The program focused on adult breast and colon cancer survivors at a community oncology practice in the southeastern United States, and consisted of an educational visit designed to identify and address QOL changes that occurred as a result of chemotherapy. The QOL of Cancer Survivors (QOL-CS) survey administered before and after the visit analyzed QOL metrics, which were combined with program evaluation data to assess physical, psychosocial, social, and spiritual well-being changes that may have occurred as a result of program participation. Differences in QOL-CS scores did not represent statistically significant changes in QOL for program participants. However, program evaluation responses identified perceived changes in QOL as a result of participating in cancer treatment and a subsequent cancer survivorship program, which demonstrated clinical significance for program participants. Physical, psychosocial, social, and spiritual well-being measures were affected by program participation. Improvement in distress related to the initial cancer diagnosis and family distress were the most significant reported changes, and male gender and advanced age were associated with improved psychosocial well-being.

    The present paper is a longitudinal study which aims to develop and deliver cancer nursing education conferences in Honduras using volunteer nurse educators. This program intends to (1) perform site assessments of work environments and resources for cancer care in Honduras, (2) develop cancer nursing education programs, (3) survey conference participants continuing education needs, (4) deliver cancer nursing education conferences, and (5) share data with local and global partners for future cancer programs. The study draws on a longitudinal program development with site assessments, data collection, and educational conferences at two time points. Assessments and surveys were used for conference development and delivery by volunteer nurse educators. Site assessments and conferences were delivered twice. Data were collected regarding assessments and surveys to inform program development. Survey data revealed that 65 % had internet access. Participants desired more information about handling of chemotherapy, symptom management, and palliative care. Volunteer nurse educators perform site assessments and develop educational programming for cancer nurses. Local and global partners should explore internet-based programs between site visits to create sustainable education programs.

    The Alabama Department of Public Health (ADPH) is collaborating with the National Cancer Institute to develop detailed profiles of underserved Alabama communities most at risk for cancer. These profiles will be combined with geocoded data to create a pilot project, Cancer Prevention for Alabama's Underserved Populations: A Focused Approach. The project's objectives are to provide the ADPH's cancer prevention programs with a more accurate and cost-effective means of planning, implementing, and evaluating its prevention activities in an outcomes-oriented and population-appropriate manner. The project links geocoded data from the Alabama Statewide Cancer Registry with profiles generated by the National Cancer Institute's cancer profiling system, Consumer Health Profiles. These profiles have been successfully applied to market-focused cancer prevention messages across the United States. The ADPH and the National Cancer Institute will evaluate the efficacy of using geocoded data and lifestyle segmentation information in strategy development and program implementation. Alabama is the first state in the nation not only to link geocoded cancer registry data with lifestyle segmentation data but also to use the National Cancer Institute's profiles and methodology in combination with actual state data.

    Cervical cancer (CC) is second most common cause of cancer in Latin America and is a leading cause of cancer mortality among women. In 2015, an estimated 74,488 women will be diagnosed with CC in Latin America and 31,303 will die of the disease. CC mortality is projected to increase by 45% by 2030 despite human papillomavirus (HPV) vaccination and screening efforts. In this setting, the goal was of the current study was to examine CC control efforts in Latin America and identify deficiencies in these efforts that could be addressed to reduce CC incidence and mortality. The authors found that HPV vaccination has been introduced in the majority of Latin American countries, and there is now a need to monitor the success (or shortcomings) of these programs and to ensure that these programs are sustainable. This topic was also reviewed in light of emerging data demonstrating that visual inspection with acetic acid and HPV DNA testing without Papanicolaou tests have efficacy from a screening perspective and are good alternatives to cytology-based screening programs. Overall, there is a need to build capacity for CC control in Latin America and the best strategy will depend on the country/region and must be tailored to meet the needs of the population as well as available resources.

    A description is presented of a Material Control System Simulator (MCSS) program for determination of material accounting uncertainty and system response to particular adversary action sequences that constitute plausible material diversion attempts. The program is intended for use in situations where randomness, uncertainty, or interaction of adversary actions and material control system components make it difficult to assess safeguards effectiveness against particular material diversion attempts. Although MCSS may be used independently in the design or analysis of material handling and processing systems, it has been tailored toward the determination of material accountability and the response of material control systems to adversary action sequences.

    2010-07-01

    Full Text Available Abstract Background Aneuploidy has long been recognized to be associated with cancer. A growing body of evidence suggests that tumorigenesis, the formation of new tumors, can be attributed to some extent to errors occurring at the mitotic checkpoint, a major cell cycle control mechanism that acts to prevent chromosome missegregation. However, so far no statistical model has been available quantify the role aneuploidy plays in determining cancer. Methods We develop a statistical model for testing the association between aneuploidy loci and cancer risk in a genome-wide association study. The model incorporates quantitative genetic principles into a mixture-model framework in which various genetic effects, including additive, dominant, imprinting, and their interactions, are estimated by implementing the EM algorithm. Results Under the new model, a series of hypotheses tests are formulated to explain the pattern of the genetic control of cancer through aneuploid loci. Simulation studies were performed to investigate the statistical behavior of the model. Conclusions The model will provide a tool for estimating the effects of genetic loci on aneuploidy abnormality in genome-wide studies of cancer cells.

  15. [Making Decisions on the Resources for Cancer Control

    We aim at modelling the strategic decision making process in case of devoting resources to a governmental cancer control program. We use a model based on the theory of Analytic Hierarchy Process. In this article we describe the characteristic features of such a decision making process and reveal the complexity of the problem underlying the decisions. A second article will present and discuss the results from the application of the AHP model. Interventions which are capable of decreasing the burden of cancer in a society need strategic approach. Decisions on interventions seem inevitable to be based on and balance between the priorities and the available resources. There is not much doubt about it that the reason for setting the priorities arises on the one hand from the scarcity of resources. On the other hand, priorities evolve on other bases, and are supposed to "guide" health policy makers devoting the scarce resources. In general, a strategic mode of thought has been based on assumptions, which, in case of cancer control enhance the necessity to assess information on cancer and cancer patients, and to understand the factors contributing towards better health. The capabilities of the NCCP achieving its aims by preventing the development of cancer diseases (primary prevention), by making use of the means of early detection and appropriate therapy (secondary prevention), and by providing modern (comprehensive) tertiary prevention are inevitably affected by the priorities. Health policy should assume a responsibility for enforcing certain priorities and should be aware of the long-term interest of the population. To solve the problem we restrict the model to a simple three level one, representing the goals, the criteria, and the alternatives of the resource allocation. We determine "decreasing the burden of cancer" as the overall goal. "Distributive justice" "cost-effectiveness", "human rights", "evidences", and "standpoints of a community" serve as criteria, while

    The American Cancer Society is a leader in the development of cancer survivorship resources. One resource of the American Cancer Society is the I Can Cope program, an educational program for cancer survivors and their families. Evaluations of this program indicate that cancer patients highly rate its objectives. Yet, there are gaps in the understanding of the full impact of the program on diverse cancer survivors. In this study, the authors used a randomized trial to evaluate the program. Participants included 140 low-income survivors (79% Black; 38% breast cancer) from community hospitals who were randomized to 4 sessions of I Can Cope (learning about cancer; understanding cancer treatments; relieving cancer pain; and keeping well in mind and body) or 4 sessions of a wellness intervention (humor, meditation, relaxation, and music therapy). The authors' primary outcome was "met information needs." After controlling for covariates, their analysis indicated that I Can Cope was no more effective than the wellness intervention in addressing survivor information needs relative to the learning objectives. Participants provided high overall ratings for both interventions. Self-efficacy for obtaining advice about cancer, age, education, and income were associated with information needs. Educational programs tailored to levels of self-efficacy and patient demographics may be needed.

  18. Nurse's role in controlling cancer pain.

    Nurses spend more time with patients than any other member of the healthcare team. They play a critical, active and very important part in controlling cancer patients' pain and alleviating suffering. In controlling cancer pain the nurse needs to understand the psychological state of the cancer patient, cancer pain, cancer pain treatment, deleterious effects of unrelieved cancer pain and patient's socio cultural background. She needs to understand that there are two types of pain, nociceptive and neuropathic pains and that 80% of the cancer patients in pain could have 2 or more than 4 different pains at the same time. Nurses' role in controlling cancer pain include believing the patient, assessing pain, identifying the root of the problem, planning the care, administering medication, evaluating effectiveness, ensuring good pain control and individualizing treatment. It also includes nursing interventions such as giving tender nursing care, preventing pain, educating, advocating, communicating, comforting, supporting, and counseling the patient. The nurse must use both pharmacological and non pharmacological treatments to individualize treatment, know all the drugs that are used for the treatment of Cancer Pain, how these drugs relieve pain and what their side effects are. She must use the WHO guidelines to treat pain and must choose the right drug, right dose, given at the right times, with the right intervals and to the right patient. She must evaluate effectiveness of treatment, give PRN doses for breakthrough pain and recommend for specific changes. The role of the nurse is to anticipate the patient's pain needs, advocate for the patient for what feels appropriate for him within his cultural context and incorporate the patient's belief. The nurse can physically relieve pain by promoting comfort, support painful area, gentleness in handling the patient and use nursing treatments. The nurse can recommend physiotherapy, (TENS)/Acupuncture, Occupational therapy

    This study explains and demonstrates the design method for a control system with a load disturbance observer. Observer gains are determined by linear programming (LP) in terms of the Routh-Hurwitz stability criterion and the final-value theorem. In addition, the control model has a feedback structure, and feedback gains are determined to be the linear quadratic regulator. The simulation results confirmed that compared with the conventional method, the output estimated by our proposed method converges to a reference input faster when a load disturbance is added to a control system. In addition, we also confirmed the effectiveness of the proposed method by performing an experiment with a DC motor.

    2017-01-01

    Neuropeptides act as neurohormones, neurotransmitters and/or neuromodulators. Neuropeptides maintain physiological homeostasis and are paramount in molecular mechanisms of disease progression and regulation, including in cancer. Neuropeptides, by their definition, originate and are secreted from the neuronal cells, they are able to signal to neighboring cells or are released into the blood flow, if they act as neurohormones. The majority of neuropeptides exert their functions through G protein-coupled receptors, with certain exceptions. Although previous studies indicate that neuropeptides function in supporting proliferation of malignant cells in many types of solid tumor, the antitumorigenic action of the neuropeptides and their receptors, for example, in gastric cancers and chondrosarcoma, were also reported. It is known that epigenetically modified chromatin regulates molecular mechanisms involved in gene expression and malignant progression. The epigenetic modifications are genetically heritable, although they do not cause changes in DNA sequence. DNA methylation, histone modifications and miRNA expression are subject to those modifications. While there is substantial data on epigenetic regulation of neuropeptides, the epigenetic control of cancer by neuropeptides is considered to be uncharted territory. The aim of the current review is to describe the involvement of neuropeptides in the epigenetic machinery of cancer based on data obtained from our laboratory and from other authors.

    AIM:To investigate barriers to colorectal cancer (CRC) screening in a community population. METHODS:We conducted a community-based case-control study in an urban Chinese population by questionnaire. Cases were selected from those completing both a fecal occult blood test (FOBT) case and colonoscopy in a CRC screening program in 2004. Control groups were matched by gender, age group and community. Control 1 included those having a positive FOBT but refusing a colonoscopy. Control 2 included those who refused both an FOBT and colonoscopy. RESULTS:The impact of occupation on willingness to attend a colorectal screening program differed by gender. P for heterogeneity was 0.009 for case vs control group 1, 0.01 for case versus control group 2, and 0.80 for control group 1 vs 2. Poor awareness of CRC and its screening program, characteristics of screening tests, and lack of time affected the screening rate. Financial support, fear of pain and bowel preparation were barriers to a colonoscopy as a screening test. Eighty-two percent of control group 1 and 87.1% of control group 2 were willing attend if the colonoscopy was free, but only 56.3% and 53.1%,respectively, if it was self-paid. Multivariate odds ratios for case vs control group 1 were 0.10 among those unwilling to attend a free colonoscopy and 0.50 among those unwilling to attend a self-paid colonoscopy. CONCLUSION:Raising the public awareness of CRC and its screening, integrating CRC screening into the health care system, and using a painless colonoscopy would increase its screening rate.

    Full Text Available O objetivo deste artigo é demonstrar alguns desafios para a implementação de ações programáticas visando ao controle do câncer do colo do útero no Estado do Amazonas, Brasil. Foram analisados os relatórios do Programa Viva Mulher do Amazonas referentes à coleta e qualidade das lâminas e os dados de mortalidade por esta causa registrados no DATASUS para os períodos 2001 a 2005. Os resultados apresentam que no período não houve o aumento na cobertura da coleta de exames de Papanicolaou, embora tenha havido uma discreta melhora na qualidade das lâminas; as taxas de mortalidade por câncer de colo de útero estão aumentando, e situam-se em patamares acima dos encontrados no país e na região norte. A análise desses resultados sugere a necessidade de haver um esforço, por parte da gestão do Programa no Amazonas, na capacitação de profissionais e dos gerentes dos serviços, visando aumentar a captação das mulheres sob maior risco.The purpose of this study is to present a number of challenges facing the implementation of program actions regarding the control of cervical cancer in the State of Amazonas, Brazil. Reports of the Viva Mulher program in Amazonas on Papanicolaou screening tests and the quality of cervical samples and mortality rates from this disease taken from DATASUS were analyzed for the 2001 to 2005 period. The results show no increase in the population covered by the Papanicolaou screening test in this period, although there was a small improvement in the quality of cervical samples. However, mortality rates for cervical cancer are increasing in this reason, and are higher than the rates for Brazil as a whole and for the North region of the country. Analysis of these results suggests the need for local program managers, to make efforts to build the capacity of health-care professionals and service managers, with a view to increasing Papanicolaou screening test coverage for high-risk women.

    The growing evidence linking dietary patterns to the incidence and prevention of chronic disease has prompted a number of prominent health and scientific agencies to publish dietary guidelines for the public. Some dietary guidelines address specific diseases, such as cancer or heart disease; others focus on overall health promotion. This situation has created a demand for nutrition education and information programs for the public. Increasingly, supermarkets are seen as potential sites for effective consumer education. Eat for Health is a joint research study by the National Cancer Institute (NCI) and Giant Food Inc., a regional supermarket chain in the Washington-Baltimore area. The study's goal was to test the feasibility of supermarkets as a site for consumer nutrition education. Eat for Health's educational focus was diet and cancer control issues in the context of dietary patterns that promote health. Particular attention was paid to reduction of fat intake and increases in consumption of dietary fiber from grains, vegetables, and fruits. Analysis of program results is currently underway; data should be available in early 1990.

    1998-01-01

    This paper deals with the problem of synthesizing or designing a feedback controller of fixed dynamic order. The closed loop specifications considered here are given in terms of a target performance vector representing a desired set of closed loop transfer functions connecting various signals. In general these point targets are unattainable with a fixed order controller. By enlarging the target from a fixed point set to an interval set the solvability conditions with a fixed order controller are relaxed and a solution is more easily enabled. Results from the parametric robust control literature can be used to design the interval target family so that the performance deterioration is acceptable, even when plant uncertainty is present. It is shown that it is possible to devise a computationally simple linear programming approach that attempts to meet the desired closed loop specifications.

    In this review the effect of internet-based support programs on psychosocial and physical symptoms resulting from cancer diagnosis and treatment is analyzed. Selection of studies was based on the following criteria: (non-)randomized controlled trials, performed in adult cancer patients, comparing quantitative psychosocial and/or physical outcomes of an internet-based support program with (a) comparison group(s). Literature search yielded 2032 studies of which 16 fulfilled the eligibility criteria. Three different internet-based support programs were identified: social support groups, online therapy for psychosocial/physical symptoms, and online systems integrating information, support, and coaching services. Outcomes improved by these programs in nine studies. Especially fatigue, social support, and distress improved, regardless of the program type. All online systems showed positive effects, mainly for social support and quality of life. This analysis indicates that internet-based support programs are effective in improving psychosocial and physical symptoms in cancer patients.

    CERN Document Server

    Fuchs, N; Fuchs, Norbert E.; Schwitter, Rolf

    1995-01-01

    Writing specifications for computer programs is not easy since one has to take into account the disparate conceptual worlds of the application domain and of software development. To bridge this conceptual gap we propose controlled natural language as a declarative and application-specific specification language. Controlled natural language is a subset of natural language that can be accurately and efficiently processed by a computer, but is expressive enough to allow natural usage by non-specialists. Specifications in controlled natural language are automatically translated into Prolog clauses, hence become formal and executable. The translation uses a definite clause grammar (DCG) enhanced by feature structures. Inter-text references of the specification, e.g. anaphora, are resolved with the help of discourse representation theory (DRT). The generated Prolog clauses are added to a knowledge base. We have implemented a prototypical specification system that successfully processes the specification of a simple...

    Full Text Available Background: In recent years, the interest in Qigong as an alternative therapy has grown following reports of its ability to regulate psychological factors in cancer patients. This is a case series to evaluate the outcome measures of Qigong when used as an adjunct to standard medical care to treat insomnia and stress in cancer patients. Patients and methods: The Qigong program was applied to four cancer patients with insomnia, stress, and anxiety. The program consisted of 30-min sessions involving exercise, patting of the 12 meridians, and spontaneous breathing exercises three times a week for a period of 4 weeks. The Pittsburgh Sleep Quality Index was measured as the primary outcome, while the Stress Scale, the State–Trait Anxiety Inventory, and the Functional Assessment Cancer Therapy–General determined the secondary outcomes. Insomnia, stress, and anxiety levels were examined weekly, while quality of life was examined on the first visit and the last visit. Results: The Pittsburgh Sleep Quality Index and Stress Scale scores were reduced after conduct of the Qigong program. Conclusion: This study could provide a better understanding of Qigong’s influence on insomnia and stress in cancer patients. However, a larger controlled trial should be conducted to confirm these findings.

    Lung cancer is the leading cause of cancer mortality in the USA. Within the past decade, two large trials (the National Lung Screening Trial Research and the International Early Lung Cancer Action Program) confirmed a significant role for low-dose CT (LDCT) screening in identifying early stages of cancer leading to reduced mortality in high-risk patients. Given the evidence, the US Preventive Services Task Force issued a recommendation in favour of LDCT screening for high-risk individuals. Despite the strong support for LDCT among physicians who treat lung cancer and cumulative data demonstrating a survival benefit for screening and early detection, it took more than a decade for lung cancer screening to be embraced at the policy level. With many lives lost in the interim, did we really need a randomized controlled trial to make this decision?

    Cancer control is a long-term work. Cancer research and intervention really need the support of cohort study. In the recent years, more and more cohort studies on cancer control were conducted in China along with the increased ability of scientific research in China. Since 2010, Cancer Hospital, Chinese Academy of Medical Sciences, collaborated with Lanzhou University and the Worker' s Hospital of Jinchuan Group Company Limited, have carried out a large-scale cohort study on cancer, which covered a population of more than 50 000 called " Jinchang cohort". Since 2012, a National Key Public Health Project, "cancer screening in urban China" , has been conducted in Jinchang, which strengthened the Jinchang cohort study. Based on the Jinchang cohort study, historical cohort study, cross-sectional study and prospective cohort study have been conducted, which would provide a lot of evidence for the cancer control in China.

    The incidence and mortality of breast cancer is in an increasing trend. In contrast to the global breast cancer situation, the prevention and control is challenging in China. Some suggestions are presented to the project of breast cancer prevention and control in China. Combining the global screening experiences with the epidemiological features of Chinese female breast cancer, aims to improve the population screening and early detection rate. Standardizing clinical diagnosis and treatment practice, aims to increase the efficacy and decrease the mortality. Intervening lifestyle and dietary behaviors, and intends to reduce risk exposure and incidence. Building national breast cancer registry provides preventive strategies. Great efforts should be made to carry out large sample multicenter clinical trails and translational research on the prevention and cotrol of breast cancer coordiated by health care service and science and technology administrations. Breast cancer prevention and control has a long way to go in China.

    Cancer control organizations commonly refer to the critical role of clinical practice guidelines to support the best possible cancer care. But how can a cancer care program ensure the systematic implementation of those guidelines? The goals of this article are to describe the process of developing a cancer control system driven by knowledge management, to highlight the key elements of this system and to foster discussion on the implementation of such frameworks. In order to promote best cancer practices within an expanded radiation service model for the province of Alberta, we developed an integrated conceptual framework for knowledge management. We identified six key elements of a knowledge management framework for the cancer program: evidence-based provincial guidelines, funding decisions, harmonized care pathways, targeted knowledge transfer projects, performance measurement and feedback to the system. We are establishing a process to characterize the explicit linkages and accountabilities between each of these elements as part of a broader cancer care quality agenda. We will implement the framework to support the start-up of the first of three new radiation treatment services in the province. The basic elements of a guidelines-supported cancer care system are not in doubt; how to unambiguously engage them within an integrated care system remains an area of intense interest.

    Full Text Available Inhibitory molecules of the B7/CD28 family play a key role in the induction of immune tolerance in the tumor microenvironment. The programmed death-1 receptor (PD-1, with its ligands PD-L1 and PD-L2, constitutes an important member of these inhibitory pathways. The relevance of the PD-1/PD-L1 pathway in cancer has been extensively studied and therapeutic approaches targeting PD-1 and PD-L1 have been developed and are undergoing human clinical testing. However, PD-L2 has not received as much attention and its role in modulating tumor immunity is less clear. Here, we review the literature on the immunobiology of PD-L2, particularly on its possible roles in cancer-induced immune suppression and we discuss the results of recent studies targeting PD-L2 in cancer.

    Full Text Available Lung cancer is an important and common cancer that constitutes a major public health problem, but early detection of small cell lung cancer can significantly improve the survival rate of cancer patients. A number of serum biomarkers have been used in the diagnosis of lung cancers; however, they exhibit low sensitivity and specificity.We used biochemical methods to measure blood levels of lactate dehydrogenase (LDH, C-reactive protein (CRP, Na+, Cl-, carcino-embryonic antigen (CEA, and neuron specific enolase (NSE in 145 small cell lung cancer (SCLC patients and 155 non-small cell lung cancer and 155 normal controls. A gene expression programming (GEP model and Receiver Operating Characteristic (ROC curves incorporating these biomarkers was developed for the auxiliary diagnosis of SCLC.After appropriate modification of the parameters, the GEP model was initially set up based on a training set of 115 SCLC patients and 125 normal controls for GEP model generation. Then the GEP was applied to the remaining 60 subjects (the test set for model validation. GEP successfully discriminated 281 out of 300 cases, showing a correct classification rate for lung cancer patients of 93.75% (225/240 and 93.33% (56/60 for the training and test sets, respectively. Another GEP model incorporating four biomarkers, including CEA, NSE, LDH, and CRP, exhibited slightly lower detection sensitivity than the GEP model, including six biomarkers. We repeat the models on artificial neural network (ANN, and our results showed that the accuracy of GEP models were higher than that in ANN. GEP model incorporating six serum biomarkers performed by NSCLC patients and normal controls showed low accuracy than SCLC patients and was enough to prove that the GEP model is suitable for the SCLC patients.We have developed a GEP model with high sensitivity and specificity for the auxiliary diagnosis of SCLC. This GEP model has the potential for the wide use for detection of SCLC in less

    Full Text Available Introduction The goals of this study were to determine U.S. states with Comprehensive Cancer Control plans that include genomics in some capacity and to review successes with and barriers to implementation of genomics-related cancer control initiatives. Methods This study was conducted in two phases. Phase one included a content analysis of written state Comprehensive Cancer Control plans (n = 30 for terms related to genomics, or “genomic components” (n = 18. The second phase involved telephone interviews with the Comprehensive Cancer Control plan coordinators in states with plans that contained genomic components (n = 16. The interview was designed to gather more detailed information about the genomics-related initiatives within the state’s Comprehensive Cancer Control plan and the successes with and barriers to plan implementation, as defined by each state. Results Eighteen of the 30 Comprehensive Cancer Control plans analyzed contained genomics components. We noted a large variability among these 18 plans in the types of genomics components included. Nine (56% of the 16 states interviewed had begun to implement the genomics components in their plan. Most states emphasized educating health care providers and the public about the role of genomics in cancer control. Many states consider awareness of family history to be an important aspect of their Comprehensive Cancer Control plan. Approximately 67% of states with family history components in their plans had begun to implement these goals. Virtually all states reported they would benefit from additional training in cancer genetics and general public health genomics. Conclusion The number of states incorporating genomics into their Comprehensive Cancer Control plans is increasing. Family history is a public health application of genomics that could be implemented more fully into Comprehensive Cancer Control plans.

    To improve cancer pain management, the Medical Oncology Department of Sun Yat-sen University Cancer Center (SYSUCC) launched the Good Pain Management (GPM) Ward Program, which has been recognized by the Chinese Ministry of Health and promoted throughout the nation. This retrospective case-control study was designed to evaluate the effectiveness of the program. Patients diagnosed with malignant solid tumors with bone metastasis were eligible. Patients who were admitted 6 months before the initiation of the GPM program were used as the control group, and patients admitted 6 months after the initiation of the program were used as the GPM group. The pain-reporting rate and pain management index (PMI) were calculated. The pain levels before and after pain management were compared. A total of 475 patients (244 in the control group and 231 in the GPM group) were analyzed. The pain-reporting rate of the GPM group was significantly higher than that of the control group (62.8% vs. 37.7%,P< 0.001). The PMI of the GPM group was significantly higher than that of the control group (0.083 vs. -0.261,P< 0.001). Therefore, the GPM Ward Program improved the pain management of cancer patients and provided experience for improving cancer pain management in the future.

    The Stockholm Cancer Prevention Program (SCPP) is a community-based program aimed at reducing cancer incidence and mortality by reducing risk factors related to life-style: dietary habits, tobacco use, and sunbathing. The program, which came about as a result of a political initiative and commitment, has as its dietary objectives to reduce fat intake to 30% of energy and to increase fiber intake to 30 g/day. SCPP strives to achieve these goals by simultaneously affecting food supply and food demand. To date, the program collaborates with 12 municipalities and several large occupational health services and restaurant chains. It has developed cook books for caterers and the general public and has organized food fairs targeting policymakers and those working with food, education, or health promotion. SCPP emphasizes collaboration across sectors of society and has initiated contests for students studying food service technology and for retailers with the aim of promoting dietary change. The intervention is based on the principles and strategies of community organization.

    Background:Ovarian cancer is a leading gynecological malignancy.We investigated the prognostic value of programmed cell death 5 (PDCD5) in patients with ovarian cancer.Methods:Expression levels ofPDCD5 mRNA and protein were examined in six ovarian cancer cell lines (SKOV3,CAOV3,ES2,OV1,3AO,and HOC1A) and one normal ovarian epithelial cell line (T29) using reverse transcription polymerase chain reaction,Westem blotting,and flow cytometry.After inducing PDCD5 induction in SKOV3 cells or treating this cell line with taxol or doxorubicin (either alone or combined),apoptosis was measured by Annexin V-FITC/propidium iodide staining.Correlations between PDCD5 protein expression and pathological features,histological grade,FIGO stage,effective cytoreductive surgery,and serum cancer antigen-125 values were evaluated in patients with ovarian cancer.Results:PDCD5 mRNA and protein expression were downregulated in ovarian cancer cells.Recombinant human PDCD5 increased doxorubicin-induced apoptosis in SKOV3 cells (15.96 ± 2.07%,vs.3.17 ± 1.45% in controls).In patients with ovarian cancer,PDCD5 expression was inversely correlated with FIGO stage,pathological grade,and patient survival (P < 0.05,R =0.7139 for survival).Conclusions:PDCD5 expression is negatively correlated with disease progression and stage in ovarian cancer.Therefore,measuring PDCD5 expression may be a good method of determining the prognosis of ovarian cancer patients.

    Full Text Available In 2011, the Division of Cancer Prevention and Control (DCPC, at the United States Centers for Disease Control and Prevention (CDC, released a three-year funding opportunity announcement (FOA for a competitive, non-research cooperative agreement. The agreement enhanced the capacities of state health departments to promote the application of best practices for evidence-based breast cancer genomics through education, surveillance, and policy activities. The FOA required that applicants focus on activities related to hereditary breast and ovarian cancer (HBOC. The DCPC funded three states: Georgia, Michigan, and Oregon. Georgia was a first-time recipient of cancer genomics funding, whereas Michigan and Oregon had long standing activities in cancer genomics and had received CDC funding in the past. By the end of the funding period, each state had well-functioning and impactful state-based programs in breast cancer genomics. This article highlights the impact of a few key state activities by using CDC’s Science Impact Framework. There were challenges to implementing public health genomics programs, including the need to develop relevant partnerships, the highly technical nature of the subject matter, a lack of genetic services in certain areas, and the difficulty in funding genetic services. Georgia, Michigan, and Oregon have served as models for others interested in initiating or expanding cancer genomics programs, and they helped to determine what works well for promoting and integrating public health genomics into existing systems.

    We report here a tumor-targeting masked phototherapeutic agent 1 (PT-1). This system contains SN-38—a prodrug of the topoisomerase I inhibitor irinotecan. Topoisomerase I is a vital enzyme that controls DNA topology during replication, transcription, and recombination. An elevated level of topoisomerase I is found in many carcinomas, making it an attractive target for the development of effective anticancer drugs. In addition, PT-1 contains both a photo-triggered moiety (nitrovanillin) and a cancer targeting unit (biotin). Upon light activation in cancer cells, PT-1 interferes with DNA re-ligation, diminishes the expression of topoisomerase I, and enhances the expression of inter alia mitochondrial apoptotic genes, death receptors, and caspase enzymes, inducing DNA damage and eventually leading to apoptosis. In vitro and in vivo studies showed significant inhibition of cancer growth and the hybrid system PT-1 thus shows promise as a programmed photo-therapeutic (“phototheranostic”).

    The primary objective of the Advanced Emissions Control Development Program (AECDP) is to develop practical, cost-effective strategies for reducing the emissions of air toxics from coal-fired boilers. The project goal is to effectively control air toxic emissions through the use of conventional flue gas clean-up equipment such as electrostatic precipitators (ESPs), fabric filters (baghouses - BH), and wet flue gas desulfurization systems (WFGD). Development work concentrated on the capture of trace metals, fine particulate, hydrogen chloride and hydrogen fluoride, with an emphasis on the control of mercury. The AECDP project is jointly funded by the US Department of Energy's Federal Energy Technology Center (DOE), the Ohio Coal Development Office within the Ohio Department of Development (OCDO), and Babcock and Wilcox, a McDermott company (B and W). This report discusses results of all three phases of the AECDP project with an emphasis on Phase III activities. Following the construction and evaluation of a representative air toxics test facility in Phase I, Phase II focused on characterization of the emissions of mercury and other air toxics and the control of these emissions for typical operating conditions of conventional flue gas clean-up equipment. Some general comments that can be made about the control of air toxics while burning a high-sulfur bituminous coal are as follows: (1) particulate control devices such as ESP's and baghouses do a good job of removing non-volatile trace metals, (2) particulate control devices (ESPs and baghouses) effectively remove the particulate-phase mercury, but the particulate-phase mercury was only a small fraction of the total for the coals tested, (3) wet scrubbing can effectively remove hydrogen chloride and hydrogen fluoride, and (4) wet scrubbers show good potential for the removal of mercury when operated under certain conditions, however, for certain applications, system enhancements can be required to achieve

    2015-12-01

    Traditionally, postdoctoral training programs largely have focused efforts within a single discipline or closely related fields. Yet, addressing the complex questions around cancer prevention and control increasingly requires the ability to work and communicate across disciplines in order to gain a perspective that encompasses the multilevel and multifaceted issues involved with this public health issue. To address this complexity, a transdisciplinary training program was implemented to cultivate the professional and scientific development of the postdoctoral fellows in Washington University in St Louis School of Medicine's Division of Public Health Sciences and NCI-funded centers (Community Networks Program Center and Transdisciplinary Research in Energetics in Cancer Center). Fellows are matched with primary mentors and assemble a multidisciplinary mentoring team. Structured programs support the transition of fellows from disciplinary trainees to independent transdisciplinary scholars and provide exposure to multiple disciplines. This article describes the training program, challenges encountered in implementation, solutions to those problems, and the metrics employed to evaluate the program's success. The goal of the program is to train emerging investigators in the conceptual bases, language, and practices that underlie a transdisciplinary perspective on cancer prevention and control research, to create an infrastructure for continued cross-discipline dialogue and collaboration, and to develop disseminable strategies for such training.

    Pancreatic cancer is estimated to be the 12th most common cancer in the United States in 2014 and yet this malignancy is the fourth leading cause of cancer-related death in the United States. Late detection and resistance to therapy are the major causes for its dismal prognosis. Apoptosis is an actively orchestrated cell death mechanism that serves to maintain tissue homoeostasis. Cancer develops from normal cells by accruing significant changes through one or more mechanisms, leading to DNA damage and mutations, which in a normal cell would induce this programmed cell death pathway. As a result, evasion of apoptosis is one of the hallmarks of cancer cells. PDAC is notoriously resistant to apoptosis, thereby explaining its aggressive nature and resistance to conventional treatment modalities. The current review is focus on understanding different intrinsic and extrinsic pathways in pancreatic cancer that may affect apoptosis in this disease.

    Pancreatic cancer is a devastating disease and predicting the status of the patients becomes an important and urgent issue. The authors explore the applicability of inductive logic programming (ILP) method in the disease and show that the accumulated clinical laboratory data can be used to predict disease characteristics, and this will contribute to the selection of therapeutic modalities of pancreatic cancer. The availability of a large amount of clinical laboratory data provides clues to aid in the knowledge discovery of diseases. In predicting the differentiation of tumour and the status of lymph node metastasis in pancreatic cancer, using the ILP model, three rules are developed that are consistent with descriptions in the literature. The rules that are identified are useful to detect the differentiation of tumour and the status of lymph node metastasis in pancreatic cancer and therefore contributed significantly to the decision of therapeutic strategies. In addition, the proposed method is compared with the other typical classification techniques and the results further confirm the superiority and merit of the proposed method.

  7. Infections and cancer: debate about using vaccines as a cancer control tool.

    In 2012, Infectious Agents and Cancer commissioned a thematic series collection of articles on Prevention of HPV related cancer. The articles have attracted wide interest and stimulated debate, including about the utility of vaccines in cancer control. The application of vaccines to cancer control fulfills a promise envisioned at the turn of the 20th century when remarkable experiments showed that some cancers were caused by infections. This suggested the possibility of applying infection-control strategies to cancer control. Vaccines represent the most practical cost-effective technology to prevent wide human suffering and death from many acute infectious diseases, such as small pox or polio. Hitherto applied to control of acute fatal infections, vaccines, if developed, might provide a potent way to control cancer. The articles in the HPV thematic series show success in developing and applying a vaccine against human papilloma virus (HPV). A vaccine is also available against hepatitis B virus (HBV), which causes liver cancer. These vaccines augment the tools available to control the associated cancers. Scientific endeavor continues for six other cancer-associated infections, mostly viruses. Not surprisingly, debate about the safety of vaccines targeting cancer has been triggered in the scientific community. Questions about safety have been raised for those populations where other means to control these cancers may be available. Although it is difficult to quantify risk from vaccines in individuals where other cancer control services exist, it is likely to be low. Vaccines are much safer today than before. Technological advancement in vaccine development and manufacture and improved regulatory review and efficient distribution have minimized substantially the risk for harm from vaccines. Formal and informal debate about the pros and cons of applying vaccines as a cancer control tools is ongoing in scientific journals and on the web. Infectious Agents and Cancer

    Novel strategies for cancer treatment involving blockade of immune inhibitors have shown significant progress toward understanding the molecular mechanism of tumor immune evasion. The preclinical findings and clinical responses associated with programmed death-1 (PD-1) and PD-ligand pathway blockade seem promising, making these targets highly sought for cancer immunotherapy. In fact, the anti-PD-1 antibodies, pembrolizumab and nivolumab, were recently approved by the US FDA for the treatment of unresectable and metastatic melanoma resistant to anticytotoxic T-lymphocyte antigen-4 antibody (ipilimumab) and BRAF inhibitor. Here, we discuss strategies of combining PD-1/PD-ligand interaction inhibitors with other immune checkpoint modulators and standard-of-care therapy to break immune tolerance and induce a potent antitumor activity, which is currently a research area of key scientific pursuit.

    The 1951 Tuberculosis Control Law of Japan was amended extensively and has been in effect since April, 2005. The revision of the National Tuberculosis Program (NTP) is to respond to the tremendous changes that have occurred during the last 50 years in tuberculosis epidemiology and in the environment in tuberculosis control implementation. In this review, the main points and framework of the revisions were summarized and the perspective of the development of new technical innovations relevant to each area of the revised TB control legislation is discussed. Also, challenges of Japan's NTP in the recent future are discussed, including the controversies over the proposed abolishment of the Tuberculosis Control Law. 1. IMMUNIZATION: In the revision of NTP, the BCG vaccination of elementary school and junior-high school entrants was discontinued. In order to strengthen the early primary vaccination for infants, the new Law has adopted the direct vaccination scheme omitting tuberculin testing prior to immunization. This program is implemented to young babies, i.e., less than six months old, as defined by the decree. It is a heavy responsibility for the municipalities to ensure the high coverage of immunization when the period of legal vaccination is rather strictly limited practically to the fourth to sixth months after birth. The safe direct vaccination is another new challenge where appropriate management of the Koch's phenomenon or similar reactions should be warranted. 2. CHEMOPROPHYLAXIS: Though unfortunately suspended for some legal reason currently, the expansion and improvement of chemoprophylaxis, or treatment of latent tuberculosis infection, to cover anyone with higher risk of clinical development of TB would have a tremendous effect in Japan, especially since 90% of patients who developed TB were infected tens of years ago. The technical innovations in diagnosis of TB infection such as QuantiFERON will be very helpful. Development of new drugs or drug regimens

    Self-management training is one of the ways to empower patients to cope with disease. The aim of this before-and-after quasi-experimental study was to determine effects of a teach-back self-management training method on breast cancer patient happiness. Fifty breast cancer patients who visited the Park-e Neshat Limited Surgery Clinic in Kerman, Iran were randomly divided into intervention and control groups after convenience sampling and checking for inclusion eligibility. Data were collected using a demographic questionnaire and the Oxford Happiness Inventory before and after teach-back training and analyzed using SPSS 23. Findings showed no significant difference between mean happiness scores in the two groups before the intervention. However, after the intervention, the mean happiness score in the intervention group increased from 37.2 to 62.9, while it decreased from 41.4 to 29.8 in the control group. These changes were statistically significant (p<0.001). Even after controlling for the effect of confounding factors such as residence location and history of cancer education, the observed differences between the groups were statistically significant (p<0.001). A teach-back self-management training program can increase happiness levels in breast cancer patients. Therefore, the use of this method is recommended to improve self-management and increase happiness.

  16. Approximate Dynamic Programming for Self-Learning Control

    2005-01-01

    This paper introduces a self-learning control approach based on approximate dynamic programming. Dynamic programming was introduced by Bellman in the 1950's for solving optimal control problems of nonlinear dynamical systems. Due to its high computational complexity, the applications of dynamic programming have been limited to simple and small problems. The key step in finding approximate solutions to dynamic programming is to estimate the performance index in dynamic programming. The optimal control signal can then be determined by minimizing (or maximizing) the performance index. Artificial neural networks are very efficient tools in representing the performance index in dynamic programming. This paper assumes the use of neural networks for estimating the performance index in dynamic programming and for generating optimal control signals, thus to achieve optimal control through self-learning.

An importa nt part of the task of supervision focuses on the detection and the diagnosis of various situatio ns of faults which can affect the process. Methods of fault detection and diagnosis (FDD are different from the type of knowledge about the process that they require. They can be classifi ed as data-driven, analytical, or knowledge- based approach. A collaborative FDD approach that c ombines the strengths of various heterogeneous FDD methods is able to maximize diagn ostic performance.

    Full Text Available The timing of lung maturation is controlled precisely by complex genetic and cellular programs. Lung immaturity following preterm birth frequently results in Respiratory Distress Syndrome (RDS and Broncho-Pulmonary Dysplasia (BPD, which are leading causes of mortality and morbidity in preterm infants. Mechanisms synchronizing gestational length and lung maturation remain to be elucidated. In this study, we designed a genome-wide mRNA expression time-course study from E15.5 to Postnatal Day 0 (PN0 using lung RNAs from C57BL/6J (B6 and A/J mice that differ in gestational length by ∼30 hr (B6controlling lung maturation. We identified both temporal and strain dependent gene expression patterns during lung maturation. For time dependent changes, cell adhesion, vasculature development, and lipid metabolism/transport were major bioprocesses induced during the saccular stage of lung development at E16.5-E17.5. CEBPA, PPARG, VEGFA, CAV1 and CDH1 were found to be key signaling and transcriptional regulators of these processes. Innate defense/immune responses were induced at later gestational ages (E18.5-20.5, STAT1, AP1, and EGFR being important regulators of these responses. Expression of RNAs associated with the cell cycle and chromatin assembly was repressed during prenatal lung maturation and was regulated by FOXM1, PLK1, chromobox, and high mobility group families of transcription factors. Strain dependent lung mRNA expression differences peaked at E18.5. At this time, mRNAs regulating surfactant and innate immunity were more abundantly expressed in lungs of B6 (short gestation than in A/J (long gestation mice, while expression of genes involved in chromatin assembly and histone modification were expressed at lower levels in B6 than in A/J mice. The present study systemically mapped key regulators

    Purpose: To evaluate the performance of the first years since the beginning of a mammographic population-based screening program. Materials and methods: Women aged 49–69 were invited biennially for two-view film-screen mammography and double reading without arbitration was performed. Interval cancers (ICs) from 2001 to 2006 were identified using screening archives, local pathology archives, and hospital discharge records. The proportional incidence of IC was determined considering breast cancers expected without screening. Three offsite radiologists experienced in breast cancer screening blindly evaluated mammograms prior to diagnosis, randomly mixed with negative mammograms (1:2 ratio). Cases unrecalled at review were considered as true ICs, those recalled by only one reviewer as minimal signs, and those recalled by two or three reviewers as missed cancers. T and N stage of the reviewed ICs were evaluated and compared. Results: A total of 86,276 first level mammograms were performed. Mean recall rate was 6.8% at first and 4.6% at repeat screening. We had 476 screen-detected cancers and 145 ICs (10 of them ductal carcinomas in situ). Absolute incidence was 17 per 10,000 screening examinations. Invasive proportional incidence was 19% (44/234) in the first year, 39% (91/234) in the second year, and 29% (135/468) in the two-year interval. Of 145 ICs, 130 (90%) were reviewed mixed with 287 negative controls: 55% (71/130) resulted to be true ICs, 24% (31/130) minimal signs, and 22% (28/130) missed cancers. The rate of ICs diagnosed in the first year interval was 21% (15/71) for true ICs, 46% (13/28) for missed cancers, and 39% (12/31) for minimal signs, with a significant difference of true ICs rate compared to missed cancers rate (p = 0.012). A higher rate of T3 and T4 stages was found for missed cancers (18%, 5/28) compared to minimal signs (6%, 2/31) or true ICs (8%, 6/71), while the rate of N2 and N3 stage for both minimal signs (19%, 6/31) or missed cancers (25

    Background Interventions addressing cancer survivors’ post-treatment concerns can be time-intensive and require specialized staff. Research is needed to identify feasible minimal intervention strategies to improve survivors’ quality of life after treatment. Objectives The objectives of this study were to evaluate the feasibility and short-term impact of a minimal clinic intervention on breast cancer survivors’ quality of life, unmet needs, distress and cancer worry. Interventions/Methods In this randomized controlled pilot trial, we enrolled breast cancer survivors at the end of treatment and administered baseline surveys. Participants were randomized to study arm (4-week video plus educational booklet intervention group and usual care group) and completed follow-up surveys at 10 weeks. Linear regression was used to examine intervention effects on quality of life outcomes controlling for clinical and demographic factors. Open-ended questions were used to examine program satisfaction and obtain feedback to improve the intervention. Results We enrolled 92 survivors in the trial. Participants rated the intervention highly and reported feeling less isolated and having more realistic expectations about their recovery after completing the program. Despite positive qualitative findings, no significant intervention effects were observed for quality of life, unmet needs, distress or cancer worry in unadjusted or adjusted analyses. Conclusions Future research is needed to define optimal intervention elements to prepare breast cancer survivors for the post-treatment period. Implications for Practice Effective survivorship interventions may require more intensive components such as clinical input and longer follow-up periods. PMID:24831043

    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.

    Apoptosis or programmed cell death is a highly conserved genetically controlled response of metazoan cells to commit suicide. Non apoptotic programmed cell death seems to operate in single celled eukaryotes implying that evolution of PCD has preceded the evolution of multicellularity. PCD plays a crucial role in the regulation of cellular and tissue homeostasis and any aberrations in apoptosis leads to several diseases including cancer, neurodegenerative disorders and AIDS. The mechanisms by which apoptosis is controlled are varied. In some cells, members of bcl-2 family or p53 are crucial for regulating the apoptosis programme, whereas in other cells Fas ligand is more important. bcl-2 family members have a prime role in the regulation of cell death at all stages including development, whereas cell death during development is independent of p53. bcl-2 family members being localized on the outer mitochondrial membrane, control the mitochondrial homeostasis and cytochrome c redistribution and thereby regulate the cell death process. p53 promotes DNA damage mediated cell death after growth arrest and failed DNA repair. Caspases play a key role in the execution of cell death by mediating highly specific cleavages of crucial cellular proteins collectivley manifesting the apoptotic phenotype. Protein inhibitors like crm A, p35 and IAPs could prevent/control apoptosis induced by a broad array of cell death stimuli by several mechanisms specially interfering in caspase activation or caspase activity. Among endonucleases, caspase activated DNase (CAD) plays a crucial role in DNA fragmentation, a biochemical hallmark of apoptosis. As regulation of cell death seems to be as complex as regulation of cell proliferation, multiple kinase mediated regulatory mechanisms might control the apoptotic process. Thus, in spite of intensive research over the past few years, the field of apoptosis still remains fertile to unravel among others, the molecular mechanisms of cytochrome c

    Full Text Available The benefit of early breast cancer detection is the foundation for programs around the globe to reduce morbidity and mortality related to breast cancer. These programs range from educational programs targeted to women and health professionals to organized or opportunistic screening programs that target specific age groups of women.Modern mammography programs tend to follow the protocols from the randomized clinical trials, but there is variation in key program elements such as the age groups invited to screening, the screening interval, performance indicators, and the uptake rate. Until recently, the emphasis on early breast cancer detection was limited to mammography, but the steady rise in incidence and mortality in low and medium resource countries, where mammography may be unaffordable, has led to a renewal in emphasizing the incremental value of downsizing palpable tumors through physical exams. There is consensus that programs should be designed based on disease burden and available resources, but that even in low resource countries there are opportunities to reduce breast deaths through earlier diagnosis and effective treatment. Screening programs are most effective when they are organized, and program planners should consider WHO criteria and local input data as a basis for tailoring screening programs to the needs of their population.El beneficio de la detección temprana del cáncer de mama es el fundamento para programas alrededor del mundo que buscan reducir la morbilidad y mortalidad relacionada con este padecimiento.

    Of working women diagnosed with cancer, approximately one-third will have breast cancer. Communicating about their cancer plays an important role in their workplace experience. It is challenging but helpful in eliciting needed social support and accommodations. Fully understanding such communication experiences is important in order to facilitate the well-being and success of such women in their workplaces. A qualitative study permits a richer account of the details of these workplace communications, and a deeper understanding of how women manage the complex and multifaceted communication process. This study used thematic analysis of semistructured interviews from 19 women working full time at the time of their breast cancer diagnosis. We found 3 themes that encapsulated unfolding individual experiences, representing a complex interplay of challenges to maintaining a sense of personal control in workplace responses: challenges to control posed by the experience of sharing information in the workplace about the woman's cancer, women's very individual attempts to control how information about their cancer was shared, and the mixed responses of those who were told. The result was unique individual trajectories in which empathic responses tailored to the individual's needs and preferences were most helpful. These findings can provide guidance on managing cancer communication for survivors, and on how to best support and accommodate women workers with breast cancer, facilitating their ability to control how their cancer impacts their work experience. Our website (http://www.iwantedyoutoknow.ca/) provides a video, tip sheet, and other resources for facilitating supportive communication in the workplace.

    The purpose of the present study was to evaluate the influence of a mixed exercise program, including Greek traditional dances and upper body training, in physical function, strength and psychological condition of breast cancer survivors. Twenty-seven women (N = 27), who had been diagnosed and surgically treated for breast cancer, volunteered to participate in this study. The experimental group consisted of 14 women with mean age 56.6 (4.2) years. They attended supervised Greek traditional dance courses and upper body training (1 h, 3 sessions/week) for 24 weeks. The control group consisted of 13 sedentary women with mean age 57.1 (4.1) years. Blood pressure, heart rate, physical function (6-min walking test), handgrip strength, arm volume and psychological condition (Life Satisfaction Inventory and Beck Depression Inventory) were evaluated before and after the exercise program. The results showed significant increases of 19.9% for physical function, 24.3% for right handgrip strength, 26.1% for left handgrip strength, 36.3% for life satisfaction and also a decrease of 35% for depressive symptoms in the experimental group after the training program. Significant reductions of 9% for left hand and 13.7% for right hand arm volume were also found in the experimental group. Consequently, aerobic exercise with Greek traditional dances and upper body training could be an alternative choice of physical activity for breast cancer survivors, thus promoting benefits in physical function, strength and psychological condition.

    Cancer cells accommodate multiple genetic and epigenetic alterations that initially activate intrinsic (cell-autonomous) and extrinsic (immune-mediated) oncosuppressive mechanisms. Only once these barriers to oncogenesis have been overcome can malignant growth proceed unrestrained. Tetraploidization can contribute to oncogenesis because hyperploid cells are genomically unstable. We report that hyperploid cancer cells become immunogenic because of a constitutive endoplasmic reticulum stress response resulting in the aberrant cell surface exposure of calreticulin. Hyperploid, calreticulin-exposing cancer cells readily proliferated in immunodeficient mice and conserved their increased DNA content. In contrast, hyperploid cells injected into immunocompetent mice generated tumors only after a delay, and such tumors exhibited reduced DNA content, endoplasmic reticulum stress, and calreticulin exposure. Our results unveil an immunosurveillance system that imposes immunoselection against hyperploidy in carcinogen- and oncogene-induced cancers.

    Full Text Available Background & Objective: Cancer is one of the life-threatening diseases that cause the numerous changes in the life style, public interaction and social activities of the patients. Usually cancer patients have some degrees of stress and depression. This study aimed to determine the effects of educational program on stress and depression among cancer patients. Materials & Methods: This study is a semi experimental research. 52 cancer patients referred to Seyedoshohada hospital of Isfahan were selected through purposeful method and then divided into 2 groups randomly, the Cooper stress and Beck depression questionnaires were used in this study. The two groups of patients (control 24 and experimental 28 both appear for the pre test. Then after one month of applying psychological intervention only on experimental group, both the groups appeared for the post test. The data were collected and analyzed with analysis of covariance. P< 0.05 was considered as statistically significant. Results: The results of covariance showed significant differences between the 2 groups in the Cooper stress inventory (F=10.8, P<0.003 and Beck depression inventory (F=12.87, P< 0.001 and the hypothesis of study was confirmed. Conclusion: Globally, the findings proved that psychological intervention based on stress and depression reduction would be a successful approach in promoting mental health on cancer patients.

    Although cancer is a leading cause of morbidity and premature death among Latinos, there is limited knowledge of cancer-related issues and priorities of greatest significance to the Latino population, the largest minority group in the nation. This information is vital in helping to guide Latino cancer research, training, and awareness efforts at national, regional, and local levels. To help identify cancer issues of greatest relevance to Latinos, Redes En Accion, The National Hispanic/Latino Cancer Network, a major network among the National Cancer Institute's Special Populations Networks, conducted a survey of 624 key opinion leaders from around the country. Respondents were asked to rank the three cancer sites most important to Latinos in their region and the five issues of greatest significance for this population's cancer prevention and control. Recommendations were prioritized for three specific areas: 1) research, 2) training and/or professional education, and 3) awareness and/or public education. Among cancers, breast carcinoma was ranked number one, followed in order by cervical and lung carcinomas. The issues of greatest significance to Latinos were 1) access to cancer screening and care, 2) tobacco use, 3) patient-doctor communication, 4) nutrition, and 5) risk communication. This survey solicited information from scientists, health care professionals, leaders of government agencies, professional and community-based organizations, and other stakeholders in Latino health. The results laid the foundation for a national Redes En Accion Latino cancer agenda, thus providing a useful tool for individuals and organizations engaged in cancer prevention and control efforts among the Hispanic-Latino population.

    Momin, Behnoosh; Richardson, Lisa

    2017-01-01

    Chronic hepatitis B and C virus (HBV and HCV) infections are among the leading causes of preventable death worldwide. Chronic viral hepatitis is the cause of most primary liver cancer, which is the third leading cause of cancer deaths globally and the ninth leading cause of cancer deaths in the U.S. The extent to which Comprehensive Cancer Control (CCC) programs in states, tribal governments and organizations, territories, and Pacific Island jurisdictions address chronic hepatitis B and/or hepatitis C infections as risk factors for liver cancer or recommend interventions for liver cancer prevention in their CCC plans remains unknown. We searched CCC plans for this information using the search tool at http://www.cdc.gov/cancer/ncccp/ to access the content of plans for this information. A combination of key search terms including “liver cancer,” “hepatitis,” “chronic alcohol,” and “alcohol abuse” were used to identify potential content regarding liver cancer risk factors and prevention. Relevant content was abstracted for further review and classification. Of 66* CCC plans, 27% (n=18) addressed liver cancer using the above-mentioned search terms. In the 23 plans that addressed HBV and/or HCV, there were 25 goals, objectives, strategies, and outcomes aimed at reducing the incidence or prevalence of HBV and/or HCV infection. While nearly a third of CCC programs identify at least one goal, objective, strategy, outcome, or prevention program to reduce cancer burden in their CCC plans, few plans discuss specific actions needed to reduce the burden of liver cancer.

    Full Text Available Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts.Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire.Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09. There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045. Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01 and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007, while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002.Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40 were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

    On January 1, 2011, Princess Margaret Cancer Centre (PM) - University Health Network (UHN) began a five-year partnership agreement with the Kuwait Ministry of Health's Kuwait Cancer Control Center (KCCC) to enhance cancer care services. Over the course of the partnership, opportunities for improvement were identified by UHN experts in order to accelerate KCCC's development toward subspecialty cancer care. Many of these opportunities involved building a robust infrastructure to support foundational hospital operation processes and procedures. Harnessing UHN's own successes in accreditation, the partnership took advantage of the national accreditation mandate in Kuwait to initiate a quality program and drive clinical improvement at KCCC. This resulted in improved staff engagement, better awareness and alignment of administration with clinical management and a stronger patient safety culture. This article discusses the successes and lessons learned at KCCC that may provide insight to healthcare providers implementing Accreditation Canada International's accreditation framework in other countries and cultures.

    In Italy, educational programs for cancer patients are currently provided by the national government, scientific societies, and patient advocate organizations. Several gaps limit their effectiveness, including the lack of coordinated efforts, poor involvement of patient feedback in the planning of programs, as well as a lack of resources on innovative cancer-related topics. This process is parallel to a strong shift in the attitude of patients towards health in general and taking charge of their own health conditions in particular. The National Cancer Institute in the USA and the Organization of European Cancer Institutes encourage comprehensive cancer centers in providing educational programs conceived to overcome these gaps. The goal of this paper is to identify and describe the key elements necessary to develop a global patient education program and provide recommendations for strategies with practical examples for implementation in the daily activities of cancer institutes. A multidisciplinary committee was established for patient education, including patient representatives as equal partners, to define, implement, verify, and evaluate the fundamental steps for establishing a comprehensive education program. Six essential topics were identified for the program: appropriate communication of cancer epidemiology, clinical trial information, new therapeutic technologies, support in the use of medicines, psycho-oncological interventions, age-personalized approaches, and training programs for healthcare providers. Integration of these topics along with patient feedback is the key to a successful model for educational programs. An integrated educational program can transform a comprehensive cancer center to an institution that provides research and care for and with patients.

    The incidence of breast cancer and mortality from this disease remain high in countries with limited resources such as the Ukraine. Because of a lack of mammography equipment and formal screening programs, as well as educational and other factors, breast cancer is usually diagnosed in late stages in such countries. We report the experience of the PATH Breast Cancer Assistance Program in introducing a pilot breast cancer screening program in one territory of the Ukraine, the Chernihiv oblast. The program entailed educating the public, training health care providers in clinical breast examination (CBE) and mammography, opening a dedicated mammography facility, designating a center for breast cancer care, building diagnostic capacity, and fostering the formation of support groups. From 1998 to 2002, 18,000 women underwent screening with CBE and 8778 women underwent screening with mammography. When implementing the program we encountered various cultural, economic, and logistic difficulties, such as reservations about showing bare breasts in educational materials, the lack of an established system for collecting screening data, and barriers to follow-up in women with positive screening results. Screening mammography proved to be more effective in detecting small and nonpalpable lesions; 8.7% of cancers detected in the mammography group were in situ, compared with 0% in the CBE group. However, introduction of CBE as a screening modality required fewer financial resources compared with mammography and was recommended as a transitional method before the introduction of mammography screening programs in countries with limited resources. The introduction of screening was associated with favorable changes in indicators of breast cancer care, including an increase in the percentage of breast-preserving operations and new legislation to provide funding for breast cancer services. We conclude that this successful pilot program of breast cancer screening in a limited

    Violation of proliferation control is a common feature of cancer cells. We put forward the hypothesis that promoters of genes involved in the control of cell proliferation should possess intrinsic cancer specific activity. We cloned promoter regions of CDC6, POLD1, CKS1B, MCM2, and PLK1 genes into pGL3 reporter vector and studied their ability to drive heterologous gene expression in transfected cancer cells of different origin and in normal human fibroblasts. Each promoter was cloned in short (335-800 bp) and long (up to 2.3 kb) variants to cover probable location of core and whole promoter regulatory elements. Cloned promoters were significantly more active in cancer cells than in normal fibroblasts that may indicate their cancer specificity. Both versions of CDC6 promoters were shown to be most active while the activities of others were close to that of BIRC5 gene (survivin) gene promoter. Long and short variants of each cloned promoter demonstrated very similar cancer specificity with the exception of PLK1-long promoter that was substantially more specific than its short variant and other promoters under study. The data indicate that most of the important cis-regulatory transcription elements responsible for intrinsic cancer specificity are located in short variants of the promoters under study. CDC6 short promoter may serve as a promising candidate for transcription targeted cancer gene therapy.

    Cervical cancer takes the lives of more than 250,000 women each year globally, particularly in under-resourced areas of low-, middle-, and high-income countries. Options for cancer control and treatment have reached a point that there are interventions for control that could be adopted for virtually every resource and demographic situation. Women die despite the availability of attractive control options, which means that educating policy makers, women's health professionals, as well as women themselves, must become a major focus for ongoing control of this disease. The human right to life, to prevention of suffering, and to education are all key rights linked to improving the control of cervical cancer and saving the lives of women, particularly in resource-poor parts of the world.

    The Oak Ridge National Laboratory (ORNL), under sponsorship of the US Department of Energy (DOE), is conducting research that will lead to advanced, automated control of new liquid-metal-reactor (LMR) nuclear power plants. Although this program of research (entitled the Advanced Controls Program'') is focused on LMR technology, it will be capable of providing control design, test, and qualification capability for other advanced reactor designs (e.g., the advanced light water reactor (ALWR) and high temperature gas-cooled reactor (HTGR) designs), while also benefiting existing nuclear plants. The Program will also have applicability to complex, non-nuclear process control environments (e.g., petrochemical, aerospace, etc.). The Advanced Controls Program will support capabilities throughout the entire plant design life cycle, i.e., from the initial interactive first-principle dynamic model development for the process, systems, components, and instruments through advanced control room qualification. The current program involves five principal areas of research activities: (1) demonstrations of advanced control system designs, (2) development of an advanced controls design environment, (3) development of advanced control strategies, (4) research and development (R D) in human-system integration for advanced control system designs, and (5) testing and validation of advanced control system designs. Discussion of the research in these five areas forms the basis of this paper. Also included is a description of the research directions of the program. 8 refs.

  2. Case-control study of fetal microchimerism and breast cancer.

    Directory of Open Access Journals (Sweden)

    Vijayakrishna K Gadi

    Full Text Available BACKGROUND: Prior pregnancy is known to protect against development of breast cancer. Recent studies have demonstrated that pregnancy has the capacity to establish small numbers of immunologically active fetal-derived cells in the mother, a phenomenon known as fetal microchimerism (FMc. We asked whether presence of FMc, routinely acquired during pregnancy, is a protective factor for breast cancer. METHODOLOGY/PRINCIPAL FINDINGS: DNA extracts from peripheral blood specimens were obtained from a population-based case-control study of risk factors for breast cancer in women 21 to 45 years old. Specimens were tested with quantitative PCR for presence and concentrations of male DNA presumed to derive from prior pregnancies with a male fetus. Odds ratios (OR and 95% confidence intervals (CI were estimated with consideration of multiple established reproductive and environmental risk factors for breast cancer. FMc results were generated on 99 parous women, 54 with primary invasive breast cancer and 45 general population controls. FMc prevalence was 56% (25/45 and 26% (14/54 in controls and cases, respectively. Women harboring FMc were less likely to have had breast cancer (OR = 0.29, 95% CI 0.11-0.83; p = 0.02, adjusting for age, number of children, birth of a son, history of miscarriage, and total DNA tested. In addition, FMc concentrations were higher in controls versus cases (p = 0.01. Median concentrations were 2 (0-78 and 0 (0-374 fetal genomes/10(6 maternal genomes in controls and cases, respectively. CONCLUSIONS: Results suggest that the enigma of why some parous women are not afforded protection from breast cancer by pregnancy might in part be explained by differences in FMc. Mechanistic studies of FMc-derived protection against breast cancer are warranted.

  3. A Gene Regulatory Program in Human Breast Cancer.

    Molecular heterogeneity in human breast cancer has challenged diagnosis, prognosis, and clinical treatment. It is well known that molecular subtypes of breast tumors are associated with significant differences in prognosis and survival. Assuming that the differences are attributed to subtype-specific pathways, we then suspect that there might be gene regulatory mechanisms that modulate the behavior of the pathways and their interactions. In this study, we proposed an integrated methodology, including machine learning and information theory, to explore the mechanisms. Using existing data from three large cohorts of human breast cancer populations, we have identified an ensemble of 16 master regulator genes (or MR16) that can discriminate breast tumor samples into four major subtypes. Evidence from gene expression across the three cohorts has consistently indicated that the MR16 can be divided into two groups that demonstrate subtype-specific gene expression patterns. For example, group 1 MRs, including ESR1, FOXA1, and GATA3, are overexpressed in luminal A and luminal B subtypes, but lowly expressed in HER2-enriched and basal-like subtypes. In contrast, group 2 MRs, including FOXM1, EZH2, MYBL2, and ZNF695, display an opposite pattern. Furthermore, evidence from mutual information modeling has congruently indicated that the two groups of MRs either up- or down-regulate cancer driver-related genes in opposite directions. Furthermore, integration of somatic mutations with pathway changes leads to identification of canonical genomic alternations in a subtype-specific fashion. Taken together, these studies have implicated a gene regulatory program for breast tumor progression.

    Full Text Available OBJECTIVE: To identify critical screening program factors for reducing cervical cancer mortality in Colombia. MATERIAL AND METHODS: Coverage, quality, and screening follow-up were evaluated in four Colombian states with different mortality rates. A case-control study (invasive cancer and healthy controls evaluating screening history was performed. RESULTS: 3-year cytology coverage was 72.7%, false negative rate 49%, positive cytology follow-up 64.2%. There was no association between screening history and invasive cancer in two states having high cytology coverage but high false negative rates. Two states revealed association between deficient screening history and invasive cancer as well as lower positive-cytology follow-up. CONCLUSIONS: Reduced number of visits between screening and treatment is more relevant when low access to health care is present. Improved quality is a priority if access to screening is available. Suitable interventions for specific scenarios and proper appraisal of new technologies are compulsory to improve cervical cancer screening. Comprehensive process-failure audits among invasive cancer cases could improve program evaluation since mortality is a late outcome.OBJETIVO: Identificar factores críticos para reducir la mortalidad por cáncer cervical en Colombia. MATERIAL Y MÉTODOS: Se evaluó cobertura, calidad y seguimiento del tamizaje en cuatro departamentos con tasas de mortalidad diferenciales. Un estudio de casos (cáncer invasor y controles (sanos evaluó historia de tamizaje. RESULTADOS: Cobertura 72,7%; falsos negativos 49%; acceso a diagnóstico-tratamiento de HSIL 64,2%. La historia de tamizaje no se asoció con cáncer invasor en dos departamentos con elevada cobertura pero elevada proporción de falsos negativos. Dos departamentos con asociación entre historia de tamizaje deficiente y cáncer invasor tuvieron cobertura aceptable pero bajo acceso a diagnóstico-tratamiento. No hubo relación entre mortalidad

    Full Text Available Objectives: The purpose of this study is to report a case series of advanced cancer patients whose cancer pain was relieved by using autonomic nerve pharmacopuncture (ANP treatment. ANP is a subcutaneous injection therapy of mountain ginseng pharmacopuncture (MGP along the acupoints on the spine (Hua-Tuo-Jia-Ji-Xue; 0.5 cun lateral to the lower border of the spinous processes of vertebrae to enhance the immune system and to balance autonomic nerve function. Methods: Patients with three different types of cancer (gastric cancer, lung cancer, colon cancer with distant metastases with cancer pain were treated with ANP. 1 mL of MGP was injected into the bilateral Hua-Tuo-Jia-Ji-Xue on the T1-L5 sites (total 12 ─ 20 mL injection of each patient’s dorsum by using the principle of symptom differentiation. During ANP treatment, the visual analogue scale (VAS for pain was used to assess their levels of cancer pain; also, the dosage and the frequency of analgesic use were measured. Results: The cancer pain levels of all three patients improved with treatment using ANP. The VAS scores of the three patients decreased as the treatment progressed. The dosage and the frequency of analgesics also gradually decreased during the treatment period. Significantly, no related adverse events were found. Conclusion: ANP has shown benefit in controlling cancer pain for the three different types of cancer investigated in this study and in reducing the dosage and the frequency of analgesics. ANP is expected to be beneficial for reducing cancer pain and, thus, to be a promising new treatment for cancer pain.

  10. Aberrant Splicing in Cancer: Mediators of Malignant Progression through an Imperfect Splice Program Shift.

    2017-01-01

    Although the efforts to understand the genetic basis of cancer allowed advances in diagnosis and therapy, little is known about other molecular bases. Splicing is a key event in gene expression, controlling the excision of introns decoded inside genes and being responsible for 80% of the proteome amplification through events of alternative splicing. Growing data from the last decade point to deregulation of splicing events as crucial in carcinogenesis and tumor progression. Several alterations in splicing events were observed in cancer, caused by either missexpression of or detrimental mutations in some splicing factors, and appear to be critical in carcinogenesis and key events during tumor progression. Notwithstanding, it is difficult to determine whether it is a cause or consequence of cancer and/or tumorigenesis. Most reviews focus on the generated isoforms of deregulated splicing pattern, while others mainly summarize deregulated splicing factors observed in cancer. In this review, events associated with carcinogenesis and tumor progression mainly, and epithelial-to-mesenchymal transition, which is also implicated in alternative splicing regulation, will be progressively discussed in the light of a new perspective, suggesting that splicing deregulation mediates cell reprogramming in tumor progression by an imperfect shift of the splice program.

    The etiology of testicular cancer is largely unexplained. Research has mainly focused on prenatal exposures, especially to sex hormones, while less attention has been paid to exposures that may act also postnatally. As baldness has been previously associated with testicular cancer risk we focused on baldness and body hairiness, which are both associated with androgen activity. We used data of the Postnatal Exposures and Male Health (EPSAM) study, a case-control study on testicular cancer conducted in the Province of Turin, Italy, involving cases diagnosed between 1997 and 2008. Information was collected using mailed questionnaires. Analyses included 255 cases and 459 controls. We calculated ORs and 95% CIs to estimate testicular cancer risk among those who developed baldness and among those with body hairiness. We found an inverse association between testicular cancer and baldness (OR: 0.67, 95% CI: 0.46-0.98) and body hairiness (OR: 0.78, 95% CI: 0.53-1.16), although the latter had wider CIs. The inverse association between baldness and testicular cancer is consistent with the results from previous studies. These results suggest that androgens activity may influence testicular cancer risk.

    The purpose of this randomized controlled study was to investigate the effect of a pain education program (PEP) on pain intensity, patients' satisfaction with pain treatment, and patient-related barriers to pain management among Turkish patients with cancer. The study was conducted in a sample of 40 patients who were hospitalized for cancer and experiencing pain. The patients were equally randomized to either a PEP or a control group. The data were collected by means of the McGill Pain Questionnaire, the Numeric Rating Scale, and the Barrier Questionnaire-Revised. After the completion of the questionnaires at the first interview, patients in the PEP group received pain education using a pain educational booklet and an explanatory slide program that discussed the booklet's content with the patients. Patients in the control group received routine clinical care. The questionnaires were reapplied to the patients in both groups after 2, 4, and 8 weeks. Participation in a PEP was associated with decreased pain intensity scores for "present" and "least pain" during weeks 2, 4, and 8 (p satisfaction with pain treatment (p satisfaction with treatment, and decreases barriers about cancer pain management in cancer patients. Incorparation of PEP into the standard of care for cancer patients with pain may improve the quality of pain management.

    1989-01-01

    The KALI distributed robot programming and control environment is described within the context of its use in the Jet Propulsion Laboratory (JPL) telerobot project. The purpose of KALI is to provide a flexible robot programming and control environment for coordinated multi-arm robots. Flexibility, both in hardware configuration and software, is desired so that it can be easily modified to test various concepts in robot programming and control, e.g., multi-arm control, force control, sensor integration, teleoperation, and shared control. In the programming environment, user programs written in the C programming language describe trajectories for multiple coordinated manipulators with the aid of KALI function libraries. A system of multiple coordinated manipulators is considered within the programming environment as one motion system. The user plans the trajectory of one controlled Cartesian frame associated with a motion system and describes the positions of the manipulators with respect to that frame. Smooth Cartesian trajectories are achieved through a blending of successive path segments. The manipulator and load dynamics are considered during trajectory generation so that given interface force limits are not exceeded.

    Variation in the detection, signaling, and repair of DNA damage contributes to human cancer risk. To assess capacity to modulate endogenous DNA damage among radiologic technologists who had been diagnosed with breast cancer and another malignancy (breast-other; n=42), early-onset breast cancer (early-onset, age {<=} 35; n=38), thyroid cancer (n=68), long-lived cancer-free individuals (hyper-normals; n=20) and cancer-free controls (n=49) we quantified DNA damage (single strand breaks and abasic sites) in untreated lymphoblastoid cell lines using the alkaline comet assay. Komet{trademark} software provided comet tail length, % DNA in tail (tail DNA), comet distributed moment (CDM), and Olive tail moment (OTM) summarized as the geometric mean of 100 cells. Category cut-points (median and 75th percentile) were determined from the distribution among controls. Tail length (for {>=} 75% vs. below the median, age adjusted) was most consistently associated with the highest odds ratios in the breast-other, early-onset, and thyroid cancer groups (with risk increased 10-, 5- or 19-fold, respectively, with wide confidence intervals) and decreased risk among the hyper-normal group. For the other three Comet measures, risk of breast-other was elevated approximately three-fold. Risk of early-onset breast cancer was mixed and risk of thyroid cancer ranged from null to a two-fold increase. The hyper-normal group showed decreased odds ratios for tail DNA and OTM, but not CDM. DNA damage, as estimated by all Comet measures, was relatively unaffected by survival time, reproductive factors, and prior radiation treatment. We detected a continuum of endogenous DNA damage that was highest among cancer cases, less in controls, and suggestively lowest in hyper-normal individuals. Measuring this DNA damage phenotype may contribute to the identification of susceptible sub-groups. Our observations require replication in a prospective study with a large number of pre-diagnostic samples.

    Optimal impulse control problems are, in general, difficult to solve. A current research goal is to isolate those problems that lead to tractable solutions. In this paper, we identify a special class of optimal impulse control problems which are easy to solve. Easy to solve means that solution algorithms are polynomial in time and therefore suitable to the on-line implementation in real-time problems. We do this by using a paradigm borrowed from the Operations Research field. As main result, ...

    Full Text Available There are many carcinogenetic elements in industry and it is for this reason that study and research concerning the effect of these materials is carried out on a national and international level. The establishment and growth of cancer are affected by different factors in two main areas:-1 The nature of the human or animal including sex, age, point and method of entry, fat metabolism, place of agglomeration of carcinogenetic material, amount of material absorbed by the body and the immunity of the body.2 The different nature of the carcinogenetic material e.g. physical, chemical quality, degree of solvency in fat and purity of impurity of the element. As the development of cancer is dependent upon so many factors, it is extremely difficult to determine whether a causative element is principle or contributory. Some materials are not carcinogenetic when they are pure but become so when they combine with other elements. All of this creates an industrial health problem in that it is almost impossible to plan an adequate prevention and safety program. The body through its system of immunity protects itself against small amounts of carcinogens but when this amount increases and reaches a certain level the body is not longer able to defend itself. ILO advises an effective protection campaign against cancer based on the Well –equipped laboratories, Well-educated personnel, the establishment of industrial hygiene within factories, the regular control of safety systems, and the implementation of industrial health principles and research programs.

    The standard of care for metastatic prostate cancer (PCa) is androgen deprivation therapy since almost all PCa growth is initially reliant on the androgen receptor (AR).However,almost all patients develop resistance to this therapy within 18-24months,and current treatment for castration-resistant prostate cancer (CRPC) is extremely limited,despite the advent of new drugs that target the AR,such as ahiraterone and MDV3100.1 Multiple studies have associated the loss of phosphatase and tensin homolog deleted on chromosome 10(PTEN),a dual lipid and protein phosphatase that is frequently lost in prostate cancer,with the development of CRPC.2,3 Yet,multiple studies have shown that at least 20%-40%of primary PCa,which are almost always androgen sensitive,experience a loss of PTEN,4,5 while as many as 30% of CRPC tumors are PTEN-positive.6 The broad questions then facing researchers are:(i) How does PTEN loss cause CRPC?;(ii) What is the mechanism of CRPC development in PTEN+/+ tumors?;and (iii) How can CRPC tumors be inhibited in PTEN-null cells?Three new publications in recent times have come up with mechanisms that answer these questions.7-9 Two of these,both in Cancer Cell eadier this year,from the laboratories of Dr Charles Sawyers and Dr Hong Wu,address a novel negative feedback regulation between AR and PTEN,and all three,including the one from Dr Damu Tang,show that the loss of PTEN function is likely the first step towards the development of CRPC.

  2. Anti program death-1/anti program death-ligand 1 indigestive cancers

    Human tumors tend to activate the immune systemregulatory checkpoints as a means of escaping immunosurveillance.For instance, interaction between programdeath-1 (PD-1) and program death-ligand 1 (PD-L1) willlead the activated T cell to a state of anergy. PD-L1 isupregulated on a wide range of cancer cells. Anti-PD-1and anti-PD-L1 monoclonal antibodies (mAbs), calledimmune checkpoint inhibitors (ICIs), have consequentlybeen designed to restore T cell activity. Accumulatingdata are in favor of an association between PD-L1expression in tumors and response to treatment. APD-L1 expression is present in 30% to 50% of digestivecancers. Multiple anti-PD-1 (nivolumab, pembrolizumab)and anti-PD-L1 mAbs (MPDL3280A, Medi4736) areunder evaluation in digestive cancers. Preliminaryresults in metastatic gastric cancer with pembrolizumabare highly promising and phase Ⅱ will start soon. Inmetastatic colorectal cancer (CRC), a phase Ⅲ trialof MPDL3280A as maintenance therapy will shortlybe initiated. Trials are also ongoing in metastatic CRCwith high immune T cell infiltration (i.e. , microsatelliteinstability). Major challenges are ahead in order todetermine how, when and for which patients we shoulduse these ICIs. New radiologic criteria to evaluate tumorresponse to ICIs are awaiting prospective validation.The optimal therapeutic sequence and association withcytotoxic chemotherapy needs to be established. Finally,biomarker identification will be crucial to selection of patients likely to benefit from ICIs.

    A number of future DOD and NASA spacecraft such as the space based radar will be not only an order of magnitude larger in dimension than the current spacecraft, but will exhibit extreme structural flexibility with very low structural vibration frequencies. Another class of spacecraft (such as the space defense platforms) will combine large physical size with extremely precise pointing requirement. Such problems require a total departure from the traditional methods of modeling and control system design of spacecraft where structural flexibility is treated as a secondary effect. With these problems in mind, the Air Force Rocket Propulsion Laboratory (AFRPL) initiated research to develop dynamics and control technology so as to enable the future large space structures (LSS). AFRPL's effort in this area can be subdivided into the following three overlapping areas: (1) ground experiments, (2) spacecraft modeling and control, and (3) sensors and actuators. Both the in-house and contractual efforts of the AFRPL in LSS are summarized.

    Colorectal cancer is the third most frequently diagnosed cancer worldwide. Prevention of colorectal cancer initiation represents the most effective overall strategy to reduce its associated morbidity and mortality. Activating KRAS mutation (KRASmut) is the most prevalent oncogenic driver in colorectal cancer development, and KRASmut inhibition represents an unmet clinical need. We apply a systems-level approach to study the impact of KRASmut on stem cell signaling during human colon cancer initiation by performing gene set enrichment analysis on gene expression from human colon tissues. We find that KRASmut imposes the embryonic stem cell-like program during human colon cancer initiation from colon adenoma to stage I carcinoma. Expression of miR145, an embryonic SC program inhibitor, promotes cell lineage differentiation marker expression in KRASmut colon cancer cells and significantly suppresses their tumorigenicity. Our data support an in vivo plasticity model of human colon cancer initiation that merges the intrinsic stem cell properties of aberrant colon stem cells with the embryonic stem cell-like program induced by KRASmut to optimize malignant transformation. Inhibition of the embryonic SC-like program in KRASmut colon cancer cells reveals a novel therapeutic strategy to programmatically inhibit KRASmut tumors and prevent colon cancer.

    Full Text Available Pacemakers are safety-critical devices whose faulty behaviors can cause harm or even death. Often these faulty behaviors are caused due to bugs in programs used for digital control of pacemakers. We present a formal verification methodology that can be used to check the correctness of object code programs that implement the safety-critical control functions of DDD mode pacemakers. Our methodology is based on the theory of Well-Founded Equivalence Bisimulation (WEB refinement, where both formal specifications and implementation are treated as transition systems. We develop a simple and general formal specification for DDD mode pacemakers. We also develop correctness proof obligations that can be applied to validate object code programs used for pacemaker control. Using our methodology, we were able to verify a control program with millions of transitions against the simple specification with only 10 transitions. Our method also found several bugs during the verification process.

    Mammography is the best tool for early detection of Breast Cancer. In this diagnostic radiology modality it is necessary to establish the criteria to ensure the proper use and operation of the equipment used to obtain mammographic images in order to contribute to the safe use of ionizing radiation. The aim of the work was to implement at FUCAM-AC the radiation protection program which must be established for patients and radiation workers according to Mexican standards [1-4]. To achieve this goal, radiation protection and quality control manuals were elaborated [5]. Furthermore, a quality control program (QCP) in the mammography systems (analog/digital), darkroom included, has been implemented. Daily sensitometry, non-variability of the image quality, visualizing artifacts, revision of the equipment mechanical stability, compression force and analysis of repetition studies are some of the QCP routine tests that must be performed by radiological technicians of this institution as a set of actions to ensure the protection of patients. Image quality and patients dose assessment were performed on 4 analog equipment installed in 2 mobile units. In relation to dose assessment, all equipment passed the acceptance criteria (<3 mGy per projection). The image quality test showed that most images (70%)- presented artifacts. A brief summary of the results of quality control tests applied to the equipment and film processor are presented. To maintain an adequate level of quality and safety at FUCAM-AC is necessary that the proposed radiation protection program in this work is applied.

    The Arab world, stretching from Lebanon and Syria in the north, through to Morocco in the west, Yemen in the south and Iraq in the east, is the home of more than 300 million people. Cancer is already a major problem and the lifestyle changes underlying the markedly increasing rates for diabetes mean that the burden of neoplasia will only become heavier over time, especially with increasing obesity and aging of what are now still youthful populations. The age-distributions of the affected patients in fact might also indicate cohort effects in many cases. There are a number of active registries in the region and population-based data are now available for a considerable number of countries. A body of Arab scientists is also contributing to epidemiological research into the causes of cancer and how to develop effective control programs. The present review covers the relevant PubMed literature and cancer incidence data from various sources, highlighting similarities and variation in the different cancer types, with attempts to explain disparities with reference to possible environmental factors. In males, the most prevalent cancers vary, with lung, urinary bladder or liver in first place, while for females throughout the region breast cancer is the greatest problem. In both sexes, non-Hodgkins lymphomas and leukemias are relatively frequent, along with thyroid cancer in certain female populations. Adenocarcinomas of the breast, prostate and colorectum appear to be increasing. Coordination of activities within the Arab world could bring major benefits to cancer control in the eastern Mediterranean region.

    The development of robot control programs is a complex task. Many robots are different in their electrical and mechanical structure which is also reflected in the software. Specific robot software environments support the program development, but are mainly text-based and usually applied by experts in the field with profound knowledge of the target robot. This paper presents a graphical programming environment which aims to ease the development of robot control programs. In contrast to existing graphical robot programming environments, our approach focuses on the composition of parallel action sequences. The developed environment allows to schedule independent robot actions on parallel execution lines and provides mechanism to avoid side-effects of parallel actions. The developed environment is platform-independent and based on the model-driven paradigm. The feasibility of our approach is shown by the application of the sequencer to a simulated service robot and a robot for educational purpose.

    Indian women with breast cancer are usually diagnosed in advanced stages leading to poor survival. Improving breast awareness and increasing access to early diagnosis and adequate treatment has been advocated for breast cancer control. We implemented a program to increase awareness on breast cancer and access to its early detection in an occupational health care scheme in Mumbai, India. Breast awareness brochures were mailed annually between June 2013 and June 2016 to a cohort of 22,500 eligible women aged 30-69 years old receiving universal health care from an occupational health care scheme comprising of primary health centres and a referral secondary care hospital in Mumbai. Women with suspected breast cancers were provided with diagnostic investigations and treatment. Socio-demographic information and tumour characteristics were compared between the breast awareness pre-intervention period (Jan 2005-May 2013) and the breast awareness intervention period after four rounds of mailers (June 2013-June 2016). The proportion of women with early tumours and axillary lymph node negative cancers increased from 74% to 81% and 46% to 53% respectively, between the two periods. While the proportion of patients receiving breast conserving surgery increased from 39% to 51%, the proportion receiving chemotherapy decreased from 84% to 56%. Interim results following efforts to improve breast awareness and access to care in a cohort of women in an occupational health care scheme indicate early detection and more conservative treatment of breast cancers. Creating awareness and improving access to care may result in cancer down-staging.

    Full Text Available Each year, an estimated 443,000 people die of smoking-related diseases in the United States. Cigarette smoking results in more than $193 billion in medical costs and productivity losses annually.In an effort to reduce this burden, many states, the federal government, and several national organizations fund tobacco control programs and policies. For this report we reviewed existing literature on economic evaluations of tobacco control interventions. We found that smoking cessation therapies, including nicotine replacement therapy (NRT and self-help are most commonly studied. There are far fewer studies on other important interventions, such as price and tax increases, media campaigns, smoke free air laws and workplace smoking interventions, quitlines, youth access enforcement, school-based programs, and community-based programs. Although there are obvious gaps in the literature, the existing studies show in almost every case that tobacco control programs and policies are either cost-saving or highly cost-effective.

    2010-10-01

    Full Text Available Abstract Background Cancer is a rapidly increasing problem in developing countries. Access, quality and efficiency of cancer services in developing countries must be understood to advance effective cancer control programs. Health services research can provide insights into these areas. Discussion This article provides an overview of oncology health services in developing countries. We use selected examples from peer-reviewed literature in health services research and relevant publicly available documents. In spite of significant limitations in the available data, it is clear there are substantial barriers to access to cancer control in developing countries. This includes prevention, early detection, diagnosis/treatment and palliation. There are also substantial limitations in the quality of cancer control and a great need to improve economic efficiency. We describe how the application of health data may assist in optimizing (1 Structure: strengthening planning, collaboration, transparency, research development, education and capacity building. (2 Process: enabling follow-up, knowledge translation, patient safety and quality assurance. (3 Outcome: facilitating evaluation, monitoring and improvement of national cancer control efforts. There is currently limited data and capacity to use this data in developing countries for these purposes. Summary There is an urgent need to improve health services for cancer control in developing countries. Current resources and much-needed investments must be optimally managed. To achieve this, we would recommend investment in four key priorities: (1 Capacity building in oncology health services research, policy and planning relevant to developing countries. (2 Development of high-quality health data sources. (3 More oncology-related economic evaluations in developing countries. (4 Exploration of high-quality models of cancer control in developing countries. Meeting these needs will require national, regional and

    Full Text Available Abstract Background Correct control selection is crucial to the internal validity of case-control studies. Little information exists on differences between population and hospital controls in case-control studies on cancers in Chinese hospital setting. Methods We conducted three parallel case-control studies on leukemia, breast and colorectal cancers in China between 2009 and 2010, using population and hospital controls to separately match 540 incident cases by age, gender and residency at a 1:1 ratio. Demographic and lifestyle factors were measured using a validated questionnaire in face-to-face interview. Odds ratios (ORs and 95% confidence intervals (CIs were obtained using conditional logistic regression analyses. Results The two control groups had closely similar exposure distributions of 15 out of 16 factors, with the only exception being that hospital controls were less likely to have a BMI ≥ 25 (OR = 0.71, 95% CI: 0.54, 0.93. For exposure of green tea drinking, the adjusted ORs (95% CIs comparing green tealeaves intake ≥ 1000 grams annually with non-drinkers were 0.51 (0.31, 0.83 and 0.21 (0.27, 0.74 for three cancers combined, 0.06 (0.01, 0.61 and 0.07 (0.01, 0.47 for breast cancer, 0.52 (0.29, 0.94 and 0.45 (0.25, 0.82 for colorectal cancer, 0.65 (0.08, 5.63 and 0.57 (0.07, 4.79 for leukemia using hospital and population controls respectively. Conclusions The study found that hospital controls were comparable with population controls for most demographic characteristics and lifestyle factors measured, but there was a slight difference between the two control groups. Hospital outpatients provide a satisfactory control group in hospital-based case-control study in the Chinese hospital setting.

  2. Birth control pills, cigarettes, alcohol linked to liver cancer.

    1992-03-01

    Data on 74 pathologically confirmed cases of liver cancer among blacks and whites living in Los Angeles County, California were compared with 162 matched controls. The study was limited to only people with no hepatitis infection and to non-Asians. The risk of liver cancer for women who have used OCs for 5 years was 5.5 times higher than that for women who had never used OCs. This risk was 3 times higher for women who had ever used OCs. The data for women who were in their reproductive years when OCs 1st entered the market in the 1960s showed that the risk for 5 years of OC use increased to almost 30 times that of women who had never used OCs. Even though estrogens were presumed to be the risk factor since they induce liver cancer in animals, no significant association was found between estrogens used in estrogen replacement therapy and liver cancer. Overall, diabetics were at 3.3 times the risk for liver cancer compared with nondiabetics. People who had diabetes for at least 10 years had 4.3 times the risk and those dependent on insulin injections had 18.5 times the risk. Cigarette smokers had a 2.1 times greater risk of liver cancer than nonsmokers. Most of the women did not drink heavily which showed the independent effect of cigarette smoking. As of December 1991, these data represented the best data on OCs and cigarette smoking to date. The risk for heavy drinkers of alcohol (80g of alcohol/day=9 cans of beer, 9 glasses of wine, or 9 shots of spirits) was 4.7 times the risk of nondrinkers or light drinkers. It is concluded that alcohol and/or cigarettes caused 56% of liver cancer cases in men and that cigarettes and/or OCs caused 54% of liver cancer cases in women.

    Full Text Available Childhood cancer was the leading cause of death among children aged 1-14 years for 2012 in Spain. Leukemia has the highest incidence, followed by tumors of the central nervous system (CNS and lymphomas (Hodgkin lymphoma, HL, and Non-Hodgkin's lymphoma, NHL. Spatial distribution of childhood cancer cases has been under concern with the aim of identifying potential risk factors.The two objectives are to study overall spatial clustering and cluster detection of cases of the three main childhood cancer causes, looking to increase etiological knowledge.We ran a case-control study. The cases were children aged 0 to 14 diagnosed with leukemia, lymphomas (HL and NHL or CNS neoplasm in five Spanish regions for the period 1996-2011. As a control group, we used a sample from the Birth Registry matching every case by year of birth, autonomous region of residence and sex with six controls. We geocoded and validated the address of the cases and controls. For our two objectives we used two different methodologies. For the first, for overall spatial clustering detection, we used the differences of K functions from the spatial point patterns perspective proposed by Diggle and Chetwynd and the second, for cluster detection, we used the spatial scan statistic proposed by Kulldorff with a level for statistical significance of 0.05.We had 1062 cases of leukemia, 714 cases of CNS, 92 of HL and 246 of NHL. Accordingly we had 6 times the number of controls, 6372 controls for leukemia, 4284 controls for CNS, 552 controls for HL and 1476 controls for NHL. We found variations in the estimated empirical D(s for the different regions and cancers, including some overall spatial clustering for specific regions and distances. We did not find statistically significant clusters.The variations in the estimated empirical D(s for the different regions and cancers could be partially explained by the differences in the spatial distribution of the population; however, according to the

    Full Text Available The Alabama Department of Public Health (ADPH is collaborating with the National Cancer Institute to develop detailed profiles of underserved Alabama communities most at risk for cancer. These profiles will be combined with geocoded data to create a pilot project, Cancer Prevention for Alabama’s Underserved Populations: A Focused Approach. The project's objectives are to provide the ADPH's cancer prevention programs with a more accurate and cost-effective means of planning, implementing, and evaluating its prevention activities in an outcomes-oriented and population-appropriate manner. The project links geocoded data from the Alabama Statewide Cancer Registry with profiles generated by the National Cancer Institute’s cancer profiling system, Consumer Health Profiles. These profiles have been successfully applied to market-focused cancer prevention messages across the United States. The ADPH and the National Cancer Institute will evaluate the efficacy of using geocoded data and lifestyle segmentation information in strategy development and program implementation. Alabama is the first state in the nation not only to link geocoded cancer registry data with lifestyle segmentation data but also to use the National Cancer Institute’s profiles and methodology in combination with actual state data.

    1981-01-01

    The emphasis of a program to conduct digital controls research for small turboshaft engines is on engine test evaluation of advanced control logic using a flexible microprocessor based digital control system designed specifically for research on advanced control logic. Control software is stored in programmable memory. New control algorithms may be stored in a floppy disk and loaded directly into memory. This feature facilitates comparative evaluation of different advanced control modes. The central processor in the digital control is an Intel 8086 16 bit microprocessor. Control software is programmed in assembly language. Software checkout is accomplished prior to engine test by connecting the digital control to a real time hybrid computer simulation of the engine. The engine currently installed in the facility has a hydromechanical control modified to allow electrohydraulic fuel metering and VG actuation by the digital control. Simulation results are presented which show that the modern control reduces the transient rotor speed droop caused by unanticipated load changes such as cyclic pitch or wind gust transients.

    There are many methods of stable controller design for nonlinear systems. In seeking to go beyond the minimum requirement of stability, Adaptive Dynamic Programming for Control approaches the challenging topic of optimal control for nonlinear systems using the tools of  adaptive dynamic programming (ADP). The range of systems treated is extensive; affine, switched, singularly perturbed and time-delay nonlinear systems are discussed as are the uses of neural networks and techniques of value and policy iteration. The text features three main aspects of ADP in which the methods proposed for stabilization and for tracking and games benefit from the incorporation of optimal control methods: • infinite-horizon control for which the difficulty of solving partial differential Hamilton–Jacobi–Bellman equations directly is overcome, and  proof provided that the iterative value function updating sequence converges to the infimum of all the value functions obtained by admissible control law sequences; • finite-...

    Full Text Available Background: Breast cancer is one of the most prevalent cancers among women and features increasing trends of incidence rates. Worldwide, yearly about 1.67 million of new cases and 522,000 of deaths from breast cancer are registered. The aim of this study was to determine the risk factors of breast cancer in women and to identify high risk groups. Methods: In a case-control study, 170 women with breast cancer who were registered in cancer registration system from 2011 to 2015 at Dezful City, Iran, were compared with 170 healthy women with confirmation of mammography. After age matching of groups, the needed information about risk factors and demographic information including information, educational level, marital status, family history of breast cancer, age at menarche, parity, oral contraceptive use, age at first pregnancy, menopausal status, and age at menopause, breastfeeding, stress, abortion, alcohol use and smoking, hormone therapy and physical activity was collected by a questionnaire. The analysis of collected data was performed by using odds ratio and logistic regression model and SPSS software, version 16 (SPSS, Inc., Chicago, IL, USA. The statistical significance was set at a two-sided p-value of %5. Results: The results of this study showed that, women with the family history [OR: 6.78 (95% CI: 2.15-21.41] and women with the stress history [OR: 4.86 (95% CI: 2.46-9.59] had higher risk of breast canser, while women with the history of having physical activity at least once a week [OR: 0.29 (95% CI: 0.13-0.65] and women with the history breast feeding for 3 to 4 years [OR: 0.36 (95% CI: 0.16-0.81] had lower risk of breast cancer. Conclusion: It is recommended that the mentioned risk factors and protective factors be considered in first and second level (screening of preventive programs.

    The highly integrated digital electronic control (HIDEC) program will integrate the propulsion and flight control systems on an F-15 airplane at NASA Ames Research Center's Dryden Flight Research Facility. Ames-Dryden has conducted several propulsion control programs that have contributed to the HIDEC program. The digital electronic engine control (DEEC) flight evaluation investigated the performance and operability of the F100 engine equipped with a full-authority digital electronic control system. Investigations of nozzle instability, fault detection and accommodation, and augmentor transient capability provided important information for the HIDEC program. The F100 engine model derivative (EMD) was also flown in the F-15 airplane, and airplane performance was significantly improved. A throttle response problem was found and solved with a software fix to the control logic. For the HIDEC program, the F100 EMD engines equipped with DEEC controls will be integrated with the digital flight control system. The control modes to be implemented are an integrated flightpath management mode and an integrated adaptive engine control system mode. The engine control experience that will be used in the HIDEC program is discussed.

    The authors report on a method to calculate radiological risks, applicable to breast screening programs and other controlled medical exposures to ionizing radiation. In particular, it has been applied to make a risk assessment in the Valencian Breast Cancer Early Detection Program (VBCEDP) in Spain. This method is based on a parametric approach, through Markov processes, of hazard functions for radio-induced breast cancer incidence and mortality, with mean glandular breast dose, attained age and age-at-exposure as covariates. Excess relative risk functions of breast cancer mortality have been obtained from two different case-control studies exposed to ionizing radiation, with different follow-up time: the Canadian Fluoroscopy Cohort Study (1950-1987) and the Life Span Study (1950-1985 and 1950-1990), whereas relative risk functions for incidence have been obtained from the Life Span Study (1958-1993), the Massachusetts tuberculosis cohorts (1926-1985 and 1970-1985), the New York post-partum mastitis patients (1930-1981) and the Swedish benign breast disease cohort (1958-1987). Relative risks from these cohorts have been transported to the target population undergoing screening in the Valencian Community, a region in Spain with about four and a half million inhabitants. The SCREENRISK software has been developed to estimate radiological detriments in breast screening. Some hypotheses corresponding to different screening conditions have been considered in order to estimate the total risk associated with a woman who takes part in all screening rounds. In the case of the VBCEDP, the total radio-induced risk probability for fatal breast cancer is in a range between [5 x 10{sup -6}, 6 x 10{sup -4}] versus the natural rate of dying from breast cancer in the Valencian Community which is 9.2 x 10{sup -3}. The results show that these indicators could be included in quality control tests and could be adequate for making comparisons between several screening programs.

    2003-01-01

    Full Text Available The cervical cancer screening programs (CCSP have not been very efficient in the developing countries. This explains the need to foster changes on policies, standards, quality control mechanisms, evaluation and integration of new screening alternatives considered as low and high cost, as well as to regulate colposcopy practices and the foundation of HPV laboratories. Cervical cancer (CC is a disease most frequently found in poverty-stricken communities and reflecting a problem of equity at both levels gender and regional, and this, is not only due to social and economic development inequalities, but to the infrastructure and human resources necessary for primary care. For this reason, the CCSP program must be restructured, a to primarily address unprivileged rural and urban areas; b to foster actions aimed at ensuring extensive coverage as well as a similar quality of that coverage in every region; c to use screening strategies in keeping with the availability of health care services. In countries with a great regional heterogeneity, a variety of screening procedures must be regulated and standardized, including a combination of assisted visual inspection, cervical cytology and HPV detection; d regional community intervention must be set up to assess the effectiveness of using HPV detection as an strategy in addition to cervical cytology (pap smear; e the practice of colposcopy must be regulated to prevent the use of it in healthy women at a population level, thus preventing unnecessary diagnosis and treatment which not only are expensive but also causes unnecessary anxiety to women at risk; f the operation of those clinical laboratories using HPV as a detection strategy must likewise be accredited and regulated and g the CCSP program for assuring health care quality should meet the expectations of its beneficiaries, and increase the knowledge in cervical cancer related matters. Finally, though a variety of clinical tests on prophylactic and

    Full Text Available Abstract The eruption of Kaposi sarcoma (KS and aggressive non-Hodgkin lymphoma (NHL in young homosexual men in 1981 in the West heralded the onset of the human immunodeficiency virus (HIV infection epidemic, which remains one of the biggest challenges to global public health and science ever. Because KS and NHL were increased >10,000 and 50-600 times, respectively, with HIV, they were designated AIDS defining cancers (ADC. Cervical cancer (CC, increased 5-10 times was also designated as an ADC. A few other cancers are elevated with HIV, including Hodgkin lymphoma (10 times, anal cancer (15-30 times, and lung cancer (4 times are designated as non-AIDS defining cancers (NADCs. Since 1996 when combination antiretroviral therapy (cART became widely available in the West, dramatic decreases in HIV mortality have been observed and substantial decrease in the incidence of ADCs. Coincidentally, the burden of NADCs has increased as people with HIV age with chronic HIV infection. The impact of HIV infection on cancer in sub-Saharan Africa, where two thirds of the epidemic is concentrated, remains poorly understood. The few studies conducted indicate that risks for ADCs are also increased, but quantitatively less so than in the West. The risks for many cancers with established viral associations, including liver and nasopharynx, which are found in Africa, do not appear to be increased. These data are limited because of competing mortality, and cancer is under diagnosed, pathological confirmation is rare, and cancer registration not widely practiced. The expansion of access to life-extending cART in sub-Saharan Africa, through programs such as the Global Fund for AIDS, Malaria, and Tuberculosis and the US President's Emergency Program for AIDS Relief (PEPFAR, is leading to dramatic lengthening of life of HIV patients, which will likely influence the spectrum and burden of cancer in patients with HIV. In this paper, we review current literature and explore

    Cancer prevention is a broad field that crosses many disciplines; therefore, educational efforts to enhance cancer prevention research focused on interdisciplinary approaches to the field are greatly needed. In order to hasten progress in cancer prevention research, the Cancer Prevention Internship Program (CPIP) at Purdue University was designed to develop and test an interdisciplinary curriculum for undergraduate and graduate students. The hypothesis was that course curriculum specific to introducing interdisciplinary concepts in cancer prevention would increase student interest in and ability to pursue advanced educational opportunities (e.g., graduate school, medical school). Preliminary results from the evaluation of the first year which included 10 undergraduate and 5 graduate students suggested that participation in CPIP is a positive professional development experience, leading to a significant increase in understanding of interdisciplinary research in cancer prevention. In its first year, the CPIP project has created a successful model for interdisciplinary education in cancer prevention research. PMID:21533583

    Christofferson, Rebecca C; Mores, Christopher N

    2015-12-10

    Development and deployment of a successful dengue virus (DENV) vaccine has confounded research and pharmaceutical entities owing to the complex nature of DENV immunity and concerns over exacerbating the risk of DENV hemorrhagic fever (DHF) as a consequence of vaccination. Thus, consensus is growing that a combination of mitigation strategies will be needed for DENV to be successfully controlled, likely involving some form of vector control to enhance a vaccine program. We present here a deterministic compartmental model to illustrate that vector control may enhance vaccination campaigns with imperfect coverage and efficacy. Though we recognize the costs and challenges associated with continuous control programs, simultaneous application of vector control methods coincident with vaccine roll out can have a positive effect by further reducing the number of human cases. The success of such an integrative strategy is predicated on closing gaps in our understanding of the DENV transmission cycle in hyperedemic locations.

    Anterior Gradient 2 (AGR2) is a protein expressed in many solid tumor types including prostate, pancreatic, breast and lung. AGR2 functions as a protein disulfide isomerase in the endoplasmic reticulum. However, AGR2 is secreted by cancer cells that overexpress this molecule. Secretion of AGR2 was also found in salamander limb regeneration. Due to its ubiquity, tumor secretion of AGR2 must serve an important role in cancer, yet its molecular function is largely unknown. This study examined the effect of cancer-secreted AGR2 on normal cells. Prostate stromal cells were cultured, and tissue digestion media containing AGR2 prepared from prostate primary cancer 10-076 CP and adenocarcinoma LuCaP 70CR xenograft were added. The control were tissue digestion media containing no AGR2 prepared from benign prostate 10-076 NP and small cell carcinoma LuCaP 145.1 xenograft. In the presence of tumor-secreted AGR2, the stromal cells were found to undergo programmed cell death (PCD) characterized by formation of cellular blebs, cell shrinkage, and DNA fragmentation as seen when the stromal cells were UV irradiated or treated by a pro-apoptotic drug. PCD could be prevented with the addition of the monoclonal AGR2-neutralizing antibody P3A5. DNA microarray analysis of LuCaP 70CR media-treated vs. LuCaP 145.1 media-treated cells showed downregulation of the gene SAT1 as a major change in cells exposed to AGR2. RT-PCR analysis confirmed the array result. SAT1 encodes spermidine/spermine N1-acetyltransferase, which maintains intracellular polyamine levels. Abnormal polyamine metabolism as a result of altered SAT1 activity has an adverse effect on cells through the induction of PCD. PMID:27283903

    Full Text Available OBJECTIVE To analyze the influence from context characteristics in the control of tuberculosis in prisons, and the influence from the program implementation degrees in observed effects.METHODS A multiple case study, with a qualitative approach, conducted in the prison systems of two Brazilian states in 2011 and 2012. Two prisons were analyzed in each state, and a prison hospital was analyzed in one of them. The data were submitted to a content analysis, which was based on external, political-organizational, implementation, and effect dimensions. Contextual factors and the ones in the program organization were correlated. The independent variable was the program implementation degree and the dependent one, the effects from the Tuberculosis Control Program in prisons.RESULTS The context with the highest sociodemographic vulnerability, the highest incidence rate of tuberculosis, and the smallest amount of available resources were associated with the low implementation degree of the program. The results from tuberculosis treatment in the prison system were better where the program had already been partially implemented than in the case with low implementation degree in both cases.CONCLUSIONS The implementation degree and its contexts – external and political-organizational dimensions – simultaneously contribute to the effects that are observed in the control of tuberculosis in analyzed prisons.

    This feasibility study tested an instructional DVD program for improving cancer family caregivers' knowledge and preparedness in fall prevention and reducing fall occurrence among the patients they care for at home. DVD program features included training caregivers on safe mobility skills. Family caregivers of cancer patients were surveyed before and after viewing the DVD program on "Moving Safely" in the home. Cancer patients were followed 4 months postintervention to determine if fall occurrence was reduced. There was a decrease in the number of patients who fell postintervention compared with those who fell preintervention. Caregivers' perceptions of knowledge about fall prevention improved significantly after viewing the DVD. An instructional DVD program is an effective educational tool for preparing family caregivers with the knowledge and skills needed to reduce the incidence of falls in the home setting. Educators must develop programs for preparing family caregivers to perform nursing skills within the home.

    The Next Generation (NextGen) transport aircraft configurations being investigated as part of the NASA Aeronautics Subsonic Fixed Wing Project have more control surfaces, or control effectors, than existing transport aircraft configurations. Conventional flight control is achieved through two symmetric elevators, two antisymmetric ailerons, and a rudder. The five effectors, reduced to three command variables, produce moments along the three main axes of the aircraft and enable the pilot to control the attitude and flight path of the aircraft. The NextGen aircraft will have additional redundant control effectors to control the three moments, creating a situation where the aircraft is over-actuated and where a simple relationship does not exist anymore between the required effector deflections and the desired moments. NextGen flight controllers will incorporate control allocation algorithms to determine the optimal effector commands and attain the desired moments, taking into account the effector limits. Approaches to solving the problem using linear programming and quadratic programming algorithms have been proposed and tested. It is of great interest to understand their relative advantages and disadvantages and how design parameters may affect their properties. In this paper, we investigate the sensitivity of the effector commands with respect to the desired moments and show on some examples that the solutions provided using the l2 norm of quadratic programming are less sensitive than those using the l1 norm of linear programming.

    2007-08-01

    This study explored psychosocial experiences of breast cancer survivors involved in dragon boat programs. Twenty women (M(age) = 58.69, SD = 6.85) were interviewed for 45-60 min about their experiences as members of survivor dragon boat teams. Interviews were analyzed using constructivist grounded theory methods. The dragon boat program facilitated social support from women with common challenges and a shared understanding of survivorship. It also provided opportunities to (re)gain a sense of personal control, develop new identities as athletes, and overcome physical challenges. Together these elements contributed to positive psychological growth and linked to the literature on posttraumatic growth. Future physical activity interventions targeting breast cancer survivors may benefit from developing strategies that share key characteristics of dragon boating.

    Prior to 2005, 51% of children in Mexico diagnosed with cancer received no standardized optimal multidisciplinary medical care. A government-subsidized national cancer treatment program was therefore created for these patients and a National Cooperative Childhood Cancer Treatment Group was consequently formed for these patients. Pediatric patients with a proven diagnosis of leukemia, lymphoma or solid tumor and who were registered in the Popular Medical Insurance (PMI) program from January 2007 to December 2010, are described in this report. These patients had been enrolled and registered in one of the 49 nationwide certified medical institutions in Mexico. The national incidence and frequency data for childhood cancers were analyzed for the whole program. At the end of a 4-year study, the analysis revealed that 8,936 children from across Mexico had been diagnosed with cancer. The incidence rate for the PMI patients was 150.3/million/year (2010) for children of 0-18 years. The highest age incidence rate was 51.9 between 0 and 4 years and boys were the predominant group for all types of cancer. The leukemia incidence was 75.3/million/year (2010), and an average frequency of 50.75% throughout the 4 years. The overall mortality rate was measured at 5.4/100,000/year (2010). This study demonstrates a high frequency and incidence of childhood cancer and a beneficial impact of the PMI program over the quality of life in these children.

    The most prevalent types of human papillomavirus in cervical cancer in India are HPV 16 and HPV 18, found in 60.7 per cent and 16 per cent of cases respectively. A comprehensive strategy with a judicious mix of interventions on health promotion, specific protection (vaccination), early diagnosis (screening), and treatment should be instituted to prevent and control cervical cancer in India. Proponents of vaccination and screening argue for enhanced investments on these interventions based on their relative cost-effectiveness. For policymakers, the major concerns about these interventions remain affordability and cost to government. Herein we try to review comprehensively the evidence on prevention and control interventions and to recommend appropriate policies to guide public health decision-making.

    2011-01-01

    Full Text Available Recent research indicates a definite positive impact on treatment outcomes when an integrative approach that focuses on symptom control and quality of life is provided along with the standard therapeutic regimens. However implementation or practice of this approach is not seen widely due to the culture of medical training and practice. This article presents the initial development of a program for incorporating integrative care principles into an ongoing comprehensive cancer care program at a tertiary centre. The key purpose of the program being to develop, facilitate, and establish comprehensive and holistic processes including palliative care principles, that would positively enhance the quantity and quality of life of the person with disease, as well as create an environment that reflects and sustains this approach. The vision, objectives, goals, strategies, activities and results within the 7 months of implementation are documented. The new learnings gained during the process have also been noted in the hope that the model described may be used to conceptualize similar care giving facilities in other centres.

  10. Approximate Dynamic Programming in Tracking Control of a Robotic Manipulator

    Marcin Szuster

    2016-02-01

    Full Text Available This article focuses on the implementation of an approximate dynamic programming algorithm in the discrete tracking control system of the three-degrees of freedom Scorbot-ER 4pc robotic manipulator. The controlled system is included in an articulated robots group which uses rotary joints to access their work space. The main part of the control system is a dual heuristic dynamic programming algorithm that consists of two structures designed in the form of neural networks: an actor and a critic. The actor generates the suboptimal control law while the critic approximates the difference of the value function from Bellman’s equation with respect to the state. The residual elements of the control system are the PD controller, the supervisory term and an additional control signal. The structure of the supervisory term derives from the stability analysis performed using the Lyapunov stability theorem. The control system works online, the neural networks’ weights-adaptation procedure is performed in every iteration step, and the neural networks’ preliminary learning process is not required. The performance of the control system was verified by a series of computer simulations and experiments performed using the Scorbot-ER 4pc robotic manipulator.

    2012-08-01

    Full Text Available Objective: This study aims to develop a foot massage program to support care activity in reducing nausea and vomiting for cancer patients undergoing chemotherapy. Two phases, a literature review and the development of a foot massage program were conducted. The literature review was to analyze state of the art massage techniques by reviewing problems, related theories and supporting evidence. Method: Eight published studies in the English language were reviewed. A massage can be performed for different durations, from 10 minutes up to 60 minutes for three to six weeks and can be applied on various body areas. We found that the soft stroke/effleurage seems to be the best method and is most suitable for patients with cancer. It is also evident that foot massaging can be applied as a modality to reduce nausea and vomiting for cancer patients undergoing chemotherapy. Result: We developed a foot massage program specifically for patients with cancer. The foot massage program comprised of three sessions, including 1 education session, 2 preparation session, and 3 foot massage session. In the education session, patients obtain brief information about the definition of a foot massage, the benefits and contraindication of foot massaging. During the preparation phase, foot soaking and warming up are performed. Subsequently, the foot massage is applied and should last for 30 minutes. Further research is recommended to test the effectiveness of the proposed foot massage program for nausea and vomiting in cancer patients across countries including Indonesia. Key Words: Foot massage program, chemotherapy, nausea and vomiting

    Although many efforts in cancer prevention and control have routinely focused on behavioral risk factors, such as tobacco use, or on the early detection of cancer, such as colorectal cancer screening, advances in genetic testing have created new opportunities for cancer prevention through evaluation of family history and identification of cancer-causing inherited mutations. Through the collection and evaluation of a family cancer history by a trained health care provider, patients and families at increased risk for a hereditary cancer syndrome can be identified, referred for genetic counseling and testing, and make informed decisions about options for cancer risk reduction (1). Although hereditary cancers make up a small proportion of all cancers, the number of affected persons can be large, and the level of risk among affected persons is high. Two hereditary cancer syndromes for which public health professionals have worked to reduce the burden of morbidity and mortality are hereditary breast and ovarian cancer syndrome (HBOC) and Lynch syndrome.

    Full Text Available Objectives: This study compares the effects of an integrated yoga program with brief supportive therapy on distressful symptoms in breast cancer outpatients undergoing adjuvant radiotherapy. Materials and Methods: Eighty-eight stage II and III breast cancer outpatients were randomly assigned to receive yoga (n = 44 or brief supportive therapy (n = 44 prior to their radiotherapy treatment. Intervention consisted of yoga sessions lasting 60 min daily while the control group was imparted supportive therapy once in 10 days during the course of their adjuvant radiotherapy. Assessments included Rotterdam Symptom Check List and European Organization for Research in the Treatment of Cancer-Quality of Life (EORTC QoL C30 symptom scale. Assessments were done at baseline and after 6 weeks of radiotherapy treatment. Results: A GLM repeated-measures ANOVA showed a significant decrease in psychological distress (P = 0.01, fatigue (P = 0.007, insomnia (P = 0.001, and appetite loss (P = 0.002 over time in the yoga group as compared to controls. There was significant improvement in the activity level (P = 0.02 in the yoga group as compared to controls. There was a significant positive correlation between physical and psychological distress and fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, and constipation. There was a significant negative correlation between the activity level and fatigue, nausea and vomiting, pain, dyspnea, insomnia, and appetite loss. Conclusion: The results suggest beneficial effects with yoga intervention in managing cancer- and treatment-related symptoms in breast cancer patients.

    1992-06-01

    Training in the neurolinguistic programming techniques of shifting perceptual position, visual-kinesthetic dissociation, timelines, and change-history, all based on experiential cognitive processing of remembered events, leads to an increased awareness of behavioral contingencies and a more sensitive recognition of environmental cues which could serve to lower trait anxiety and increase the sense of internal control. This study reports on within-person and between-group changes in trait anxiety and locus of control as measured on the Spielberger State-Trait Anxiety Inventory and Wallston, Wallston, and DeVallis' Multiple Health Locus of Control immediately following a 21-day residential training in neurolinguistic programming. Significant with-in-person decreases in trait-anxiety scores and increases in internal locus of control scores were observed as predicted. Chance and powerful other locus of control scores were unchanged. Significant differences were noted on trait anxiety and locus of control scores between European and U.S. participants, although change scores were similar for the two groups. These findings are consistent with the hypothesis that this training may lower trait-anxiety scores and increase internal locus of control scores. A matched control group was not available, and follow-up was unfortunately not possible.

    Turbulent shear flows have triggered fundamental research in nonlinear dynamics, like transition scenarios, pattern formation and dynamical modeling. In particular, the control of nonlinear dynamics is subject of research since decades. In this publication, actuated turbulent shear flows serve as test-bed for a nonlinear feedback control strategy which can optimize an arbitrary cost function in an automatic self-learning manner. This is facilitated by genetic programming providing an analytically treatable control law. Unlike control based on PID laws or neural networks, no structure of the control law needs to be specified in advance. The strategy is first applied to low-dimensional dynamical systems featuring aspects of turbulence and for which linear control methods fail. This includes stabilizing an unstable fixed point of a nonlinearly coupled oscillator model and maximizing mixing, i.e.\\ the Lyapunov exponent, for forced Lorenz equations. For the first time, we demonstrate the applicability of genetic p...

    We investigate the familial risks of cancers of the breast and ovary, using data pooled from three population-based case-control studies of ovarian cancer that were conducted in the United States. We base estimates of the frequency of mutations of BRCA1 (and possibly other genes) on the reported occurrence of breast cancer and ovarian cancer in the mothers and sisters of 922 women with incident ovarian cancer (cases) and in 922 women with no history of ovarian cancer (controls). Segregation analysis and goodness-of-fit testing of genetic models suggest that rare mutations (frequency .0014; 95% confidence interval .0002-.011) account for all the observed aggregation of breast cancer and ovarian cancer in these families. The estimated risk of breast cancer by age 80 years is 73.5% in mutation carriers and 6.8% in noncarriers. The corresponding estimates for ovarian cancer are 27.8% in carriers and 1.8% in noncarriers. For cancer risk in carriers, these estimates are lower than those obtained from families selected for high cancer prevalence. The estimated proportion of all U.S. cancer diagnoses, by age 80 years, that are due to germ-line BRCA1 mutations is 3.0% for breast cancer and 4.4% for ovarian cancer. Aggregation of breast cancer and ovarian cancer was less evident in the families of 169 cases with borderline ovarian cancers than in the families of cases with invasive cancers. Familial aggregation did not differ by the ethnicity of the probands, although the number of non-White and Hispanic cases (N = 99) was sparse. 14 refs., 3 figs., 6 tabs.

    The cyber-physical security threat to buildings is complex, non-linear, and rapidly evolving as operational and information technologies converge and connect buildings to cyberspace. Cyberattacks on buildings can exploit smart building controls and breach corporate networks, causing financial and reputational damage. This may result in the loss of sensitive building information or the disruption of, or damage to, the systems necessary for the safe and efficient operation of buildings. For the buildings and facility infrastructure, there is a need for a robust national cybersecurity strategy for buildings, guidance on the selection and implementation of appropriate cybersecurity controls for buildings, an approach to evaluate the maturity and adequacy of the cybersecurity programs. To provide an approach for evaluating the maturity of the cybersecurity programs for building control systems, the US Department of Energy’s widely used Cybersecurity Capability and Maturity Model (C2M2) has been adapted into a building control systems version. The revised model, the Buildings-C2M2 (B-C2M2) provides maturity level indicators for cybersecurity programmatic domains. A “B-C2M2 Lite” version allows facility managers and building control system engineers, or information technology personnel to perform rapid self-assessments of their cybersecurity program. Both tools have been pilot tested on several facilities. This paper outlines the concept of a maturity model, describes the B-C2M2 tools, presents results and observations from the pilot assessments, and lays out plans for future work.

    Eighty-four women at high risk for ovarian cancer by having first-degree relatives with epithelial ovarian cancer participated in a newly established, early ovarian cancer detection program at Yale University. Participants were to be evaluated with physical examinations and circulating tumor markers at entry and every six months thereafter. Endovaginal ultrasound and color Doppler flow studies were to be performed at three and nine months following entry into the program. In addition, women were encouraged to follow American Cancer Society guidelines for mammography. Stool was checked for occult blood. Endometrial sampling was offered to post-menopausal women. No participant has developed an ovarian cancer since entering the program. One woman has been diagnosed to have breast cancer. False-positive levels of circulating tumor markers (CA 125, 4/84 [4.8 percent]; lipid-associated sialic acid in plasma, 13/84 [15.5 percent]; NB/70K, 4/84 [4.8 percent]; and urinary gonadotropin fragment, 1/65 [1.5 percent]) were observed on entry into the program. Low resistive indices (less than 0.5) were documented in 8/91 (8.8 percent) ovaries studied by the color Doppler flow technique. One participant underwent a laparotomy based on a false-positive endovaginal ultrasound examination. Tests now being employed in community practice have a high likelihood of being associated with false-positive results. Therapeutic interventions based on isolated abnormal tumor markers or ultrasound studies obtained from women with family histories of ovarian cancer may lead to inappropriate surgery. It is necessary for cancer centers to develop expertise in ovarian cancer detection techniques to advise physicians in their geographic areas appropriately about the significance of the abnormal screening test.

    This paper describes a technology for remote sharing of intelligent electro-mechanical devices. An architecture and actual system have been developed and tested, based on the proposed National Information Infrastructure (NII) or Information Highway, to facilitate programming and control of intelligent programmable machines (like robots, machine tools, etc.). Using appropriate geometric models, integrated sensors, video systems, and computing hardware; computer controlled resources owned and operated by different (in a geographic sense as well as legal sense) entities can be individually or simultaneously programmed and controlled from one or more remote locations. Remote programming and control of intelligent machines will create significant opportunities for sharing of expensive capital equipment. Using the technology described in this paper, university researchers, manufacturing entities, automation consultants, design entities, and others can directly access robotic and machining facilities located across the country. Disparate electro-mechanical resources will be shared in a manner similar to the way supercomputers are accessed by multiple users. Using this technology, it will be possible for researchers developing new robot control algorithms to validate models and algorithms right from their university labs without ever owning a robot. Manufacturers will be able to model, simulate, and measure the performance of prospective robots before selecting robot hardware optimally suited for their intended application. Designers will be able to access CNC machining centers across the country to fabricate prototypic parts during product design validation. An existing prototype architecture and system has been developed and proven. Programming and control of a large gantry robot located at Sandia National Laboratories in Albuquerque, New Mexico, was demonstrated from such remote locations as Washington D.C., Washington State, and Southern California.

    Cancer patients at a high risk of acquiring infectious diseases should be maintained in a facility where good infection control practices are followed. At our hospital, the infection control team(ICT)provides expertise, education, and support to the staff, helping them maintain proper standards, thereby minimizing the risks of infection. The ICT(established in 2004)has implemented infection control programs by employing an appropriate number of staff members after the revision of medical treatment fees in 2011. Our intervention program includes 2 general policies, namely, ordering and collection of blood cultures and intervention for the medical care of patients with positive blood cultures. In this study, we evaluated the effectiveness of our intervention for cancer patients with a positive blood culture. During the surveillance period(April 2011 to July 2012), 42 positive cases were determined to be infectious. ICT intervention was required in 37 cases. Our suggestions were accepted in 92%(34/37)of the cases, and improved outcome was estimated in 65%(22/34)of the cases. The results of our study contribute to the scientific bases on which routine clinical practices could be promoted in the future.

    AIM: Tumor formation is generally linked to an expansion of glycolytic phosphometabolite pools and aerobic glycolytic flux rates. To achieve this, tumor cells generally overexpress a special glycolytic isoenzyme, termed pyruvate kinase type M2. The present study was designed to evaluate the use of a new tumor marker, tumor M2-PK, in discriminating gastrointestinal cancer patients from healthy controls, and to compare with the reference tumor markers CEA and CA72-4.METHODS: The concentration of tumor M2-PK in body fluids could be quantitatively determined by a commercially available enzyme-linked immunosorbent assay (ELISA)-kit (ScheBo(R) Tech, Giessen, Germany). By using this kit, the tumor M2-PK concentration was measured in EDTA-plasma of 108 patients. For the healthy blood donors a cut-off value of 15 U/mL was evaluated, which corresponded to 90% specificity. Overall 108 patients were included in this study, 54 patients had a histological confirmed gastric cancer, 54 patients colorectal cancer, and 20 healthy volunteers served as controls.RESULTS: The cut-off value to discriminate patients from controls was established at 15 U/mL for tumor M2-PK. The mean tumor M2-PK concentration of gastric cancer was 26.937 U/mL. According to the TNM stage system, the mean tumor M2-PK concentration of stage Ⅰ was 16.324 U/mL, of stage Ⅱ 15.290 U/mL, of stage Ⅲ 30.289 U/mL, of stage Ⅳ127.31 U/mL, of non-metastasis 12.854 U/mL and of metastasis 35.711 U/mL. The mean Tumor M2-PK concentration of colorectal cancer was 30.588 U/mL. According to the Dukes stage system, the mean tumor M2-PK concentration of Dukes A was 16.638 U/mL, of Dukes B 22.070 U/mL, and of Dukes C 48.024 U/mL, of non-metastasis 19.501 U/mL, of metastasis 49.437 U/mL. The mean tumor M2-PK concentration allowed a significant discrimination of colorectal cancers (30.588 U/mL) from controls (10.965 U/mL) (P<0.01), and gastric cancer (26.937 U/mL) from controls (10.965 U/mL)(P<0.05).

    Full Text Available Background: Prostate cancer has been reported as the second leading cause of cancer death among men in 2013. Prevention and early detection of cancer are considered as critical factors in controlling the disease and increasing the survival of patients. Therefore, we aimed to investigate the effect of Health Belief Model (HBM-based education onknowledge and prostate cancer screening behaviors in a randomized controlled trial. Methods: This study was a non-blinded randomized controlled trial. We enrolled 210 men aged 50-70. Balanced block randomization method was used to randomize the final participants who had inclusion criteria into intervention (n=93 and control (n=87 groups. The participants of the intervention group attended training workshops based on HBM. Data were collected using three questionnaires, i.e. demographic questionnaire, Prostate Cancer Screening-Health Belief Model Scale (PCS-HBMS, and the Knowledge about Prostate Cancer Screening questionnaire, all given before and immediately one month after the intervention. Results: The mean scores of the perceived susceptibility, severity, barriers and benefits increased significantly after the intervention (P>0.05 in the intervention group. In the control group, such a difference was reported only for perceived susceptibility (P>0.05. The rate of participation in prostate cancer screening in the intervention group increased from 7.5% to 24% and 43.3% one month and three months after the intervention, respectively. Conclusion: Our findings showed that the health education programs designed based on HBM could positively affect prostate cancer preventive behaviors of individuals by improving their knowledge level and leaving positive effects on perceived susceptibility and severity as well as considering the perceived barriers, benefits and health motivations.

    Many types of cancer therapies target the tumor microenvironment, causing biochemical and morphological changes in tissues. In therapies using ultrasound activated microbubbles, vascular collapse is typically reported. Red blood cells (RBCs) that leak out of the vasculature become exposed to the ceramide that is released from damaged endothelial cells. Ceramide can induce programmed cell death in RBCs (eryptosis), and is characterized by cell shrinkage, membrane blebbing and scrambling. Since the effect of eryptotic cells on generated photoacoustics (PA) signals has not been reported, we investigated the potential PA may have for cancer treatment monitoring by using PA spectral analysis to sense eryptosis. To induce eryptosis, C2-ceramide was added to RBC suspensions and that were incubated for 24 hours at 37°C. A control and ceramide-induced sample was imaged in a vessel phantom using a high frequency PA system (VevoLAZR, 10 - 45 MHz bandwidth) irradiated with multiple wavelengths ranging from 680 to 900 nm. PA spectral parameters were measured and linked to changes in RBCs as it underwent eryptosis. These samples were examined using optical microscopy, a blood gas analyzer and an integrating sphere setup to measure optical properties (wavelengths 600 - 900 nm). The results of the experiment demonstrate how PA spectral analysis can be used to identify eryptosis at a depth of more than 1 cm into the phantom using ultrasound derived the y-intercept and mid bandfit (MBF) parameters at optical wavelengths of 800 - 900 nm. These parameters were correlated to the morphological and biochemical changes that eryptotic RBCs display. The results establish the potential of PA in cancer treatment monitoring through sensing treatment induced eryptosis.

    Monitoring the current status of cancer care is essential for effective cancer control and high-quality cancer care. To address the information needs of patients and physicians in Japan, hospital-based cancer registries are operated in 397 hospitals designated as cancer care hospitals by the national government. These hospitals collect information on all cancer cases encountered in each hospital according to precisely defined coding rules. The Center for Cancer Control and Information Services at the National Cancer Center supports the management of the hospital-based cancer registry by providing training for tumor registrars and by developing and maintaining the standard software and continuing communication, which includes mailing lists, a customizable web site and site visits. Data from the cancer care hospitals are submitted annually to the Center, compiled, and distributed as the National Cancer Statistics Report. The report reveals the national profiles of patient characteristics, route to discovery, stage distribution, and first-course treatments of the five major cancers in Japan. A system designed to follow up on patient survival will soon be established. Findings from the analyses will reveal characteristics of designated cancer care hospitals nationwide and will show how characteristics of patients with cancer in Japan differ from those of patients with cancer in other countries. The database will provide an infrastructure for future clinical and health services research and will support quality measurement and improvement of cancer care. Researchers and policy-makers in Japan are encouraged to take advantage of this powerful tool to enhance cancer control and their clinical practice.

  19. Optimal traffic control in highway transportation networks using linear programming

    KAUST Repository

    Li, Yanning

    2014-06-01

    This article presents a framework for the optimal control of boundary flows on transportation networks. The state of the system is modeled by a first order scalar conservation law (Lighthill-Whitham-Richards PDE). Based on an equivalent formulation of the Hamilton-Jacobi PDE, the problem of controlling the state of the system on a network link in a finite horizon can be posed as a Linear Program. Assuming all intersections in the network are controllable, we show that the optimization approach can be extended to an arbitrary transportation network, preserving linear constraints. Unlike previously investigated transportation network control schemes, this framework leverages the intrinsic properties of the Halmilton-Jacobi equation, and does not require any discretization or boolean variables on the link. Hence this framework is very computational efficient and provides the globally optimal solution. The feasibility of this framework is illustrated by an on-ramp metering control example.

    The key goal in energy efficient buildings is to reduce energy consumption of Heating, Ventilation, and Air- Conditioning (HVAC) systems while maintaining a comfortable temperature and humidity in the building. This paper proposes a novel stochastic control approach for achieving joint performance and power control of HVAC. We employ a constrained Stochastic Linear Quadratic Control (cSLQC) by minimizing a quadratic cost function with a disturbance assumed to be Gaussian. The problem is formulated to minimize the expected cost subject to a linear constraint and a probabilistic constraint. By using cSLQC, the problem is reduced to a semidefinite optimization problem, where the optimal control can be computed efficiently by Semidefinite programming (SDP). Simulation results are provided to demonstrate the effectiveness and power efficiency by utilizing the proposed control approach.

    Full Text Available Coated magnetite nanoparticles were linked to 68Ga complexes used in the positron emission tomography (PET for a new technical approach to detect cancer tissue with radiopharmaceuticals. By substitution of the Ga isotope with an alpha emitter the same compound could be used for cancer treatment. Furthermore the nanoparticles were connected to pH-sensitive complexes, enabling a pH-controlled assembly/disassembly and therefore the spreading of the particles in the tissue. With this novel method of combining detection and treatment simultaneously, the amount of medical exposure could be minimized for the patient. The results demonstrate that magnetite nanoparticles can effectively be functionalized with PET isotopes and pH sensitive complexes in order to use them as a new type of radiopharmaceuticals.

    Service providers rely on industrial control systems (ICS) to manage the flow of water at dams, open breakers on power grids, control ventilation and cooling in nuclear power plants, and more. In today's interconnected environment, this can present a serious cyber security challenge. To combat this growing challenge, government, private industry, and academia are working together to reduce cyber risks. The Idaho National Laboratory (INL) is a key contributor to the Department of Energy National SCADA Test Bed (NSTB) and the Department of Homeland Security (DHS) Control Systems Security Program (CSSP), both of which focus on improving the overall security posture of ICS in the national critical infrastructure. In support of the NSTB, INL hosts a dedicated SCADA testing facility which consists of multiple control systems supplied by leading national and international manufacturers. Within the test bed, INL researchers systematically examine control system components and work to identify vulnerabilities. In support of the CSSP, INL develops and conducts training courses which are designed to increase awareness and defensive capabilities for IT/Control System professionals. These trainings vary from web-based cyber security trainings for control systems engineers to more advanced hands-on training that culminates with a Red Team/ Blue Team exercise that is conducted within an actual control systems environment. INL also provides staffing and operational support to the DHS Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) Security Operations Center which responds to and analyzes control systems cyber incidents across the 18 US critical infrastructure sectors.

    Full Text Available Abstract Background Colon cancer has been classically described by clinicopathologic features that permit the prediction of outcome only after surgical resection and staging. Methods We performed an unsupervised analysis of microarray data from 326 colon cancers to identify the first principal component (PC1 of the most variable set of genes. PC1 deciphered two primary, intrinsic molecular subtypes of colon cancer that predicted disease progression and recurrence. Results Here we report that the most dominant pattern of intrinsic gene expression in colon cancer (PC1 was tightly correlated (Pearson R = 0.92, P -135 with the EMT signature-- both in gene identity and directionality. In a global micro-RNA screen, we further identified the most anti-correlated microRNA with PC1 as MiR200, known to regulate EMT. Conclusions These data demonstrate that the biology underpinning the native, molecular classification of human colon cancer--previously thought to be highly heterogeneous-- was clarified through the lens of comprehensive transcriptome analysis.

    A key outcome measure of cancer research training programs is the number of cancer-related peer-reviewed publications after training. Because program graduates do not routinely report their publications, staff must periodically conduct electronic literature searches on each graduate. The purpose of this study is to compare findings of an innovative computer-based automated search program versus repeated manual literature searches to identify post-training peer-reviewed publications. In late 2014, manual searches for publications by former R25 students identified 232 cancer-related articles published by 112 of 543 program graduates. In 2016, a research assistant was instructed in performing Scopus literature searches for comparison with individual PubMed searches on our 543 program graduates. Through 2014, Scopus found 304 cancer publications, 220 of that had been retrieved manually plus an additional 84 papers. However, Scopus missed 12 publications found manually. Together, both methods found 316 publications. The automated method found 96.2 % of the 316 publications while individual searches found only 73.4 %. An automated search method such as using the Scopus database is a key tool for conducting comprehensive literature searches, but it must be supplemented with periodic manual searches to find the initial publications of program graduates. A time-saving feature of Scopus is the periodic automatic alerts of new publications. Although a training period is needed and initial costs can be high, an automated search method is worthwhile due to its high sensitivity and efficiency in the long term.

    Ovarian cancer has received national attention as a highly virulent disease. Its lack of early warning symptoms and the failure to develop highly sensitive screening tests have led some physicians to recommend prophylactic oophorectomies to women with relatives who have had ovarian cancer. Others have recommended routine screening of otherwise normal women for CA 125, a circulating tumor marker, and ultrasound examinations. Each of these techniques is associated with substantial false-positive rates that could lead to unnecessary surgery. A review of epidemiologic data suggests that familial ovarian cancer kindreds are rare, but women with first-degree relatives who have had ovarian cancer have a significant risk themselves for developing ovarian cancer. In addition, women with a great number of ovulatory cycles are at an increased risk for the disease. Circulating tumor markers are frequently elevated in women with advanced ovarian cancer, but their value in early detection of ovarian cancer has yet to be established. Advances in endovaginal ultrasound and color Doppler flow technology have significantly improved our ability to assess pelvic organs. This article presents the background, rationale, and structure of the Yale Early Detection Program for ovarian cancer, whose goals are to identify the best techniques for diagnosing ovarian cancer in an early stage, to determine the frequency with which such tests should be employed, to assess false-positive results, and to identify women who might benefit from prophylactic oophorectomies.

    In men, data regarding breast cancer carcinogenesis are limited. The aim of our study was to describe the presence of precursor lesions adjacent to invasive male breast cancer, in order to increase our understanding of carcinogenesis in these patients. Central pathology review was performed for 1328 male breast cancer patients, registered in the retrospective joint analysis of the International Male Breast Cancer Program, which included the presence and type of breast cancer precursor lesions. In a subset, invasive breast cancer was compared with the adjacent precursor lesion by immunohistochemistry (n=83) or targeted next generation sequencing (n=7). Additionally, we correlated the presence of ductal carcinoma in situ with outcome. A substantial proportion (46.2%) of patients with invasive breast cancer also had an adjacent precursor lesion, mainly ductal carcinoma in situ (97.9%). The presence of lobular carcinoma in situ and columnar cell-like lesions were very low (cases with adjacent ductal carcinoma in situ (n=83), a complete concordance was observed between the estrogen receptor, progesterone receptor, and HER2 status of both components. Next generation sequencing on a subset of cases with invasive breast cancer and adjacent ductal carcinoma in situ (n=4) showed identical genomic aberrations, including PIK3CA, GATA3, TP53, and MAP2K4 mutations. Next generation sequencing on a subset of cases with invasive breast cancer and an adjacent columnar cell-like lesion showed genomic concordance in two out of three patients. A multivariate Cox model for survival showed a trend that the presence of ductal carcinoma in situ was associated with a better overall survival, in particular in the Luminal B HER2+ subgroup. In conclusion, ductal carcinoma in situ is the most commonly observed precursor lesion in male breast cancer and its presence seems to be associated with a better outcome, in particular in Luminal B HER2+ cases. The rate of lobular carcinoma in situ and

    Full Text Available Objective. To estimate the annual cost of the National Cervical Cancer Screening Program (CCSP of the Mexican Institute of Social Security (IMSS. Materials and methods. This cost analysis examined regional coverage rates reported by IMSS. We estimated the number of cytology, colposcopy, biopsy and pathology evaluations, as well as the diagnostic test and treatment costs for cervical intraepithelial neoplasia grade II and III (CIN 2/3 and cervical cancer. Diagnostic test costs were estimated using a micro-costing technique. Sensitivity analyses were performed. Results. The cost to perform 2.7 million cytology tests was nearly 38 million dollars, which represents 26.1% of the total program cost (145.4 million. False negatives account for nearly 43% of the program costs. Conclusion. The low sensitivity of the cytology test generates high rates of false negatives, which results in high institutional costs from the treatment of undetected cervical cancer cases.

    Full Text Available The Human Papillomavirus (HPV vaccines have been widely introduced in the national immunization programs in most of the medium and high income countries following endorsement from national and international advisory bodies. HPV vaccine is unique and its introduction is challenging in many ways - it is the first vaccine developed to prevent any cancer, the vaccine is gender specific, it targets adolescent females who are difficult to reach by any health intervention programs. It is not unusual for such a vaccine to face scepticism and reservations not only from lay public but also from professionals in spite of the clinical trial results convincingly and consistently proving their efficacy and safety. Over the last few years millions of doses of the HPV vaccine have been administered round the world and the efficacy and safety data have started coming from the real life programs. A comprehensive cervical cancer control program involving HPV vaccination of the adolescent girls and screening of the adult women has been proved to be the most cost-effective approach to reduce the burden of cervical cancer. The present article discusses the justification of HPV vaccination in the backdrop of natural history of cervical cancer, the mechanism of action of the vaccines, efficacy and safety data from phase III randomized controlled trials as well as from the national immunization programs of various countries.

    To compare the effects of a 3-week multimodal rehabilitation involving supervised high-intensity interval training (HIIT) on female breast cancer survivors with respect to key variables of aerobic fitness, body composition, energy expenditure, cancer-related fatigue, and quality of life to those of a standard multimodal rehabilitation program. A randomized controlled trial design was administered. Twenty-eight women, who had been treated for cancer were randomly assigned to either a group performing exercise of low-to-moderate intensity (LMIE; n = 14) or a group performing high-intensity interval training (HIIT; n = 14) as part of a 3-week multimodal rehabilitation program. No adverse events related to the exercise were reported. Work economy improved following both HIIT and LMIE, with improved peak oxygen uptake following LMIE. HIIT reduced mean total body fat mass with no change in body mass, muscle or fat-free mass (best P HIIT can be performed by female cancer survivors without adverse health effects. Here, HIIT and LMIE both improved work economy, quality of life and cancer-related fatigue, body composition or energy expenditure. Since the outcomes were similar, but HIIT takes less time, this may be a time-efficient strategy for improving certain aspects of the health of female cancer survivors.

    On the basis of the National Lung Screening Trial data released in 2011, the U.S. Preventive Services Task Force made lung cancer screening (LCS) with low-dose computed tomography (CT) a public health recommendation in 2013. The Centers for Medicare and Medicaid Services (CMS) currently reimburse LCS for asymptomatic individuals aged 55-77 years who have a tobacco smoking history of at least 30 pack-years and who are either currently smoking or had quit less than 15 years earlier. Commercial insurers reimburse the cost of LCS for individuals aged 55-80 years with the same smoking history. Effective care for the millions of Americans who qualify for LCS requires an organized step-wise approach. The 10-pillar model reflects the elements required to support a successful LCS program: eligibility, education, examination ordering, image acquisition, image review, communication, referral network, quality improvement, reimbursement, and research frontiers. Examination ordering can be coupled with decision support to ensure that only eligible individuals undergo LCS. Communication of results revolves around the Lung Imaging Reporting and Data System (Lung-RADS) from the American College of Radiology. Lung-RADS is a structured decision-oriented reporting system designed to minimize the rate of false-positive screening examination results. With nodule size and morphology as discriminators, Lung-RADS links nodule management pathways to the variety of nodules present on LCS CT studies. Tracking of patient outcomes is facilitated by a CMS-approved national registry maintained by the American College of Radiology. Online supplemental material is available for this article.

    Full Text Available Abstract Background To achieve widespread cancer control, a better understanding is needed of the factors that contribute to successful implementation of effective skin cancer prevention interventions. This study assessed the relative contributions of individual- and setting-level characteristics to implementation of a widely disseminated skin cancer prevention program. Methods A multilevel analysis was conducted using data from the Pool Cool Diffusion Trial from 2004 and replicated with data from 2005. Implementation of Pool Cool by lifeguards was measured using a composite score (implementation variable, range 0 to 10 that assessed whether the lifeguard performed different components of the intervention. Predictors included lifeguard background characteristics, lifeguard sun protection-related attitudes and behaviors, pool characteristics, and enhanced (i.e., more technical assistance, tailored materials, and incentives are provided versus basic treatment group. Results The mean value of the implementation variable was 4 in both years (2004 and 2005; SD = 2 in 2004 and SD = 3 in 2005 indicating a moderate implementation for most lifeguards. Several individual-level (lifeguard characteristics and setting-level (pool characteristics and treatment group factors were found to be significantly associated with implementation of Pool Cool by lifeguards. All three lifeguard-level domains (lifeguard background characteristics, lifeguard sun protection-related attitudes and behaviors and six pool-level predictors (number of weekly pool visitors, intervention intensity, geographic latitude, pool location, sun safety and/or skin cancer prevention programs, and sun safety programs and policies were included in the final model. The most important predictors of implementation were the number of weekly pool visitors (inverse association and enhanced treatment group (positive association. That is, pools with fewer weekly visitors and pools in the enhanced

    Literature regarding the development of adolescent and young adult (AYA) cancer programs has been dominantly informed by pediatric centers and practitioners. However, the majority of young adults are seen and treated at adult cancer centers, in which cancer volumes afford the development of innovative supportive care services. Although the supportive care services in adult cancer centers are helpful to AYAs, some of the most prominent and distinct issues faced by AYAs are not adequately addressed through these services alone. This article describes how the AYA Program at Princess Margaret Cancer Centre has collaborated with existing supportive care services in addition to supplying its own unique services to meet the comprehensive needs of AYAs in the domains of: symptom management (sexuality and fatigue), behavior modification (return to work and exercise), and health services (advanced cancer and survivorship). These collaborations are augmented by patient education interventions and timely referrals. The objective of this article was to assist other centers in expanding existing services to address the needs of AYA patients with cancer.

    The National Breast and Cervical Cancer Early Detection Program provides funding to tribes and tribal organizations to implement comprehensive cancer screening programs using a program model developed for state health departments. We conducted a multiple-site case study using a participatory research process to describe how 5 tribal programs implemented screening services, and to identify strategies used to address challenges in delivering services to American Indian and Alaska Native women. We analyzed data from semistructured interviews with 141 key informants, 16 focus groups with 132 program-eligible women, and program documents. Several challenges regarding the delivery of services were revealed, including implementing screening programs in busy acute-care environments, access to mammography, providing culturally sensitive care, and providing diagnostic/treatment services in rural and remote locations. Strategies perceived as successful in meeting program challenges included identifying a "champion" or main supporter of the program in each clinical setting, using mobile mammography, using female providers, and increasing the capacity to provide diagnostic services at screening sites. The results should be of interest to an international audience, including those who work with health-related programs targeting indigenous women or groups that are marginalized because of culture, geographic isolation, and/or socioeconomic position.

    The Alabama Comprehensive Cancer Control Coalition (ACCCC) has developed an integrated and coordinated approach to reducing cancer incidence, morbidity, and mortality, and to improving the quality of life for cancer survivors, their families, and their caregivers. The ACCCC is currently in a maintenance phase and a formal plan for sustainability of the coalition was needed to keep the members engaged and productive. A training session in coalition sustainability conducted in 2013 identified the following elements as essential to success: (1) increased marketing of the coalition by simplifying its mission; (2) improved networking including flexibility in coalition meeting location and attendance; (3) increased membership satisfaction through transformational leadership; (4) revision of the working structure of committees and improved accountability; and (5) enhancement of partner satisfaction with coalition activities designed to recruit and retain new partners. A self-administered membership satisfaction survey was given to assess coalition mission, meeting logistics, organization, capacity building, and coalition goals. Results indicated that the subcategories of communication, mission, and meeting logistics were rated satisfied to very satisfied on a five-point scale. Although the ACCCC had clearly written goals, improvement could be made in leadership participation and new member orientation could be improved. Most members rated their parent organization as highly involved with the ACCCC and many offered suggestions on capacity building. Results of the sustainability training have clarified the ACCCC's plans to ensure coalition viability and improve strategies to inform stakeholders of the benefits of participation in the coalition.

    With this review, the authors sought to determine what strategies have been evaluated (including the outcomes assessed) to disseminate cancer control interventions that promote the uptake of behavior change. Five topic areas along the cancer care continuum (smoking cessation, healthy diet, mammography, cervical cancer screening, and control of cancer pain) were selected to be representative. A systematic review was conducted of primary studies evaluating dissemination of a cancer control intervention. Thirty-one studies were identified that evaluated dissemination strategies in the 5 topic areas. No strong evidence currently exists to recommend any one dissemination strategy as effective in promoting the uptake of cancer control interventions. The authors conclude that there is a strong need for more research into dissemination of cancer control interventions. Future research should consider methodological issues such as the most appropriate study design and outcomes to be evaluated.

    Full Text Available During developing programs for programmable logic controllers (PLCs the concept of model-oriented design is increasingly used. In particular, usage of Simulink PLC Coder is giving the opportunity to get SCL program codefrom Simulink model which contains certain dynamic elements. Then, for example, this SCL code can be transformed to functional blocks of the Simatic S7-300 (VIPA 300 PLC. This significantly reduces the timerequired to develop code in the language of SCL and reduces requirements for specialists’ qualification when developing control systems. In this article we provide an example of PLC programming automation whenimplementing algorithms of guaranteeing control (AGC. For certain types of technological processes it is typical to contain monotonically increasing function of the effectiveness with fixed one-way restriction in regulations. Forexample, in the grinders, presses, extruders the load current of the drive is stabilized using the change of feed. Energy efficiency of these plants will increase with increasing of the set point (SP to the controller of the drive loadcurrent stabilization loop. However, an increase in SP increases the probability of triggering appropriate protection, for example, as a result of random changes in the properties of raw materials. Therefore, to avoid this accident, thepower of driving motors is often unreasonably overrated. And in this case they are used with currents equal to the half of rated.Systems of guaranteeing control (SGC are used to solve the contradiction between the need to improvethe efficiency and increasing probability of an accident.

    Full Text Available Abstract Background The Exercise and Nutrition Routine Improving Cancer Health (ENRICH study is investigating a novel lifestyle intervention aimed at improving the health behaviors of adult cancer survivors and their carers. The main purpose of the study is to determine the efficacy of lifestyle education and skill development delivered via group-based sessions on the physical activity and dietary behaviors of participants. This article describes the intervention development, study design, and participant recruitment. Methods/Design ENRICH is a randomized controlled trial, conducted in Australia, with two arms: an intervention group participating in six, two-hour face-to-face sessions held over eight weeks, and a wait-list control group. Intervention sessions are co-facilitated by an exercise physiologist and dietician. Content includes healthy eating education, and a home-based walking (utilizing a pedometer and resistance training program (utilizing elastic tubing resistance devices. The program was developed with reference to social cognitive theory and chronic disease self-management models. The study population consists of cancer survivors (post active-treatment and their carers recruited through community-based advertising and referral from health professionals. The primary outcome is seven-days of sealed pedometry. Secondary outcomes include: self-reported physical activity levels, dietary intake, sedentary behavior, waist circumference, body mass index, quality of life, and perceived social support. The outcomes will be measured at baseline (one week prior to attending the program, eight-weeks (at completion of intervention sessions, and 20-weeks. The intervention group will also be invited to complete 12-month follow-up data collection. Process evaluation data will be obtained from participants by questionnaire and attendance records.

    Full Text Available Objective. To evaluate cytology laboratories and the performance of cytotechnologists for establishing efficient external quality control for Mexico's National Program for the Prevention and Control of Cervical Cancer. Material and Methods. During January and February 1998, an on-site evaluation of all cytology laboratories of the Ministry of Health found that only 70% of the microscopes were in adequate working conditions, reagents were out of date, and working conditions were sub-optimal. A program for external quality control based on proficiency testing was established for cytotechnologists. Fifty slide sets with 20 Papanicolaou slides and 10 photographic slides were prepared. The sets were given to the cytotechnologists for evaluation and again one year later by courier. Results. Twenty-one percent of microscopes were repaired and 9% replaced; reagents were distributed and laboratory facilities improved. Only 16% of cytotechnologists passed the initial proficiency test. Cytotechnologists received a refresher training course: one year later 67% of them passed the proficiency test. To ascertain that each slide was correctly diagnosed, 41 sets were rescreened by expert cytopathologists or cytologists and their diagnoses compared to the original ones. Thirty-seven sets had 86% to 96% concordance. Conclusions. This new system for external quality control of cervical cytology allowed the opportune and reliable evaluation of the performance of cytotechnologists.

    Background Due to advances in the field of oncology, survival rates for children with cancer have improved significantly. However, these childhood cancer survivors are at a higher risk for obesity and cardiovascular diseases and for developing these conditions at an earlier age. Objective In this paper, we describe the rationale, conceptual framework, development process, novel components, and delivery plan of a behavioral intervention program for preventing unhealthy weight gain in survivors of childhood acute lymphoblastic leukemia (ALL). Methods A Web-based program, the Healthy Eating and Active Living (HEAL) program, was designed by a multidisciplinary team of researchers who first identified behaviors that are appropriate targets for weight management in childhood ALL survivors and subsequently developed the intervention components, following core behavioral change strategies grounded in social cognitive and self-determination theories. Results The Web-based HEAL curriculum has 12 weekly self-guided sessions to increase parents’ awareness of the potential impact of cancer treatment on weight and lifestyle habits and the importance of weight management in survivors’ long-term health. It empowers parents with knowledge and skills on parenting, nutrition, and physical activity to help them facilitate healthy eating and active living soon after the child completes intensive cancer treatment. Based on social cognitive theory, the program is designed to increase behavioral skills (goal-setting, self-monitoring, and problem-solving) and self-efficacy and to provide positive reinforcement to sustain behavioral change. Conclusions Lifestyle interventions are a priority for preventing the early onset of obesity and cardiovascular risk factors in childhood cancer survivors. Intervention programs need to meet survivors’ targeted behavioral needs, address specific barriers, and capture a sensitive window for behavioral change. In addition, they should be convenient

  13. Rac and Rho GTPases in cancer cell motility control

    Directory of Open Access Journals (Sweden)

    Parri Matteo

    2010-09-01

    Full Text Available Abstract Rho GTPases represent a family of small GTP-binding proteins involved in cell cytoskeleton organization, migration, transcription, and proliferation. A common theme of these processes is a dynamic reorganization of actin cytoskeleton which has now emerged as a major switch control mainly carried out by Rho and Rac GTPase subfamilies, playing an acknowledged role in adaptation of cell motility to the microenvironment. Cells exhibit three distinct modes of migration when invading the 3 D environment. Collective motility leads to movement of cohorts of cells which maintain the adherens junctions and move by photolytic degradation of matrix barriers. Single cell mesenchymal-type movement is characterized by an elongated cellular shape and again requires extracellular proteolysis and integrin engagement. In addition it depends on Rac1-mediated cell polarization and lamellipodia formation. Conversely, in amoeboid movement cells have a rounded morphology, the movement is independent from proteases but requires high Rho GTPase to drive elevated levels of actomyosin contractility. These two modes of cell movement are interconvertible and several moving cells, including tumor cells, show an high degree of plasticity in motility styles shifting ad hoc between mesenchymal or amoeboid movements. This review will focus on the role of Rac and Rho small GTPases in cell motility and in the complex relationship driving the reciprocal control between Rac and Rho granting for the opportunistic motile behaviour of aggressive cancer cells. In addition we analyse the role of these GTPases in cancer progression and metastatic dissemination.

    2015-09-01

    The prevalence of cancer pain in patients with cancer is high. The majority of efforts are spent on research in cancer treatment, but only a small fraction focuses on cancer pain. Pain in cancer patients, viewed predominantly as a secondary issue, is considered to be due to the destruction of tissues, compression of the nerves, inflammation, and secretion of biological mediators from the necrotic tumor mass. As a result, opioid drugs have remained as the primary pharmacological therapy for cancer pain for the past hundred years. This report reviews evidence that cancer pain may be produced by the metabolic effects of two byproducts of cancer-high acidity in the cancer microenvironment and the secretion of formaldehyde and its metabolites. We propose the research and development of therapeutic approaches for preemptive, short- and long-term management of cancer pain using available drugs or nutraceutical agents that can suppress or neutralize lactic acid production in combination with formaldehyde scavengers. We believe this approach may not only improve cancer pain control but may also enhance the quality of life for patients.

    The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized an international session as part of the official program of the 71st Annual Meeting of the Japanese Cancer Association to discuss the topic "Healthcare Economics: The Significance of the UN Summit non-communicable diseases (NCDs) Political Declaration in Asia." The presenters and participants discussed the growing cost of cancer in the Asian region and the challenges that are faced by the countries of Asia, all of which face budgetary and other systemic constraints in tackling and controlling cancer in the region. The session benefited from the participation of various stakeholders, including cancer researchers and representatives of the pharmaceutical industry. They discussed the significance of the UN Political Declaration on the prevention and control of NCDs (2011) as a means of boosting awareness of cancer in the Asian region and also addressed the ways in which stakeholders can cooperate to improve cancer control and treatment. Other issues that were covered included challenges relating to pharmaceutical trials in Asia and how to link knowledge and research outcomes. The session concluded with the recognition that with the onset of a super-aged society in most countries in Asia and an increasing focus on quality of life rather than quantity of life, it is more important than ever for all stakeholders to continue to share information and promote policy dialogue on cancer control and treatment.

    The viewgraphs and discussion of the NASA supersonic laminar flow control program are provided. Successful application of laminar flow control to a High Speed Civil Transport (HSCT) offers significant benefits in reductions of take-off gross weight, mission fuel burn, cruise drag, structural temperatures, engine size, emissions, and sonic boom. The ultimate economic success of the proposed HSCT may depend on the successful adaption of laminar flow control, which offers the single most significant potential improvements in lift drag ratio (L/D) of all the aerodynamic technologies under consideration. The F-16XL Supersonic Laminar Flow Control (SLFC) Experiment was conceived based on the encouraging results of in-house and NASA supported industry studies to determine if laminar flow control is feasible for the HSCT. The primary objective is to achieve extensive laminar flow (50-60 percent chord) on a highly swept supersonic wing. Data obtained from the flight test will be used to validate existing Euler and Navier Stokes aerodynamic codes and transition prediction boundary layer stability codes. These validated codes and developed design methodology will be delivered to industry for their use in designing supersonic laminar flow control wings. Results from this experiment will establish preliminary suction system design criteria enabling industry to better size the suction system and develop improved estimates of system weight, fuel volume loss due to wing ducting, turbocompressor power requirements, etc. so that benefits and penalties can be more accurately assessed.

    The purpose of the study was to develop and evaluate Taking CHARGE, a self-management intervention designed to facilitate successful transitions to survivorship after breast cancer treatment. The Taking CHARGE intervention involves a two-pronged approach building on self-regulation principles to (1) equip women with self-management skills to address concerns following breast cancer treatment, and (2) provide information about common survivorship topics. The program involved four intervention contacts, two small group meetings and two individualized telephone sessions, delivered by nurse/health educators. This paper focuses on the process evaluation findings from a preliminary test of the Taking CHARGE intervention conducted with 25 women, aged 34-66 years, completing breast cancer treatment, who were randomly assigned to the intervention group. The process evaluation was conducted to obtain systematic information about the relevance and usefulness of the self-regulation approach, informational aspects, and program delivery. The findings indicated that intervention group participants found the Taking CHARGE program to be timely, relevant, and to have high utility in dealing with concerns that exist following breast cancer treatment. The process evaluation findings provide early evidence of the usefulness of the Taking CHARGE intervention for successful transition to survivorship following breast cancer treatment.

    The PS/SL Convergence Project was launched in March 1998. Its objective is to deliver a common control as infrastructure for the CERN accelerators by year 2001. In the framework of this convergence activity, a project was launched to develop a Java Application Programming Interface (API) between programs written in the Java language and the PS and SL accelerator equipment. This Java API was specified and developed in collaboration with TJNAF. It is based on the Java CDEV [1] package that has been extended in order to end up with a CERN/TJNAF common product. It implements a detailed model composed of devices organized in named classes that provide a property-based interface. It supports data subscription and introspection facilities. The device model is presented and the capabilities of the API are described with syntax examples. The software architecture is also described.

    This book covers the most recent developments in adaptive dynamic programming (ADP). The text begins with a thorough background review of ADP making sure that readers are sufficiently familiar with the fundamentals. In the core of the book, the authors address first discrete- and then continuous-time systems. Coverage of discrete-time systems starts with a more general form of value iteration to demonstrate its convergence, optimality, and stability with complete and thorough theoretical analysis. A more realistic form of value iteration is studied where value function approximations are assumed to have finite errors. Adaptive Dynamic Programming also details another avenue of the ADP approach: policy iteration. Both basic and generalized forms of policy-iteration-based ADP are studied with complete and thorough theoretical analysis in terms of convergence, optimality, stability, and error bounds. Among continuous-time systems, the control of affine and nonaffine nonlinear systems is studied using the ADP app...

    AIM: In order to detect risk factors for esophageal cancer,a national research program was carried out during the Eighth Five-Year Plan (from 1991 to 1995). METHODS: Cixian County and Chichen County in Hebei Province were selected as the index and the control for the study fields with higher or lower incidence of esophagus cancer in China, respectively. In these areas, we investigated the pollution of three nitrogenous compounds in well water for drinking and the use of nitrogen fertilizer in farming. RESULTS: In well water, nitrate nitrogen, nitrite nitrogen and ammonia nitrogen were 8.77 mg/L, 0.014 mg/L and 0.009 mg/L in Cixian County in 1993, respectively. They were significantly higher than their levels (3.84 mg/L, 0.004 mg/L and 0.004 mg/L) in Chichen County (P<0.01, t=6.281,t=3.784,t=3.775). There was a trend that the nitrogenous compounds in well water increased from 1993 to 1996.The amount of nitrogen fertilizer used in farming was 787.6 kg per hectare land in Cixian County in 1991, significantly higher than 186 kg per hectare in Chichen County (t=9.603,P<0.001). CONCLUSION: These investigations indicate that the poilution of nitrogenous compounds in well water for drinking is closely related to the use of nitrogen fertlizer in farming, and there is a significantly positive correlation between the level of three nitrogenous compounds in well water and the mortality ofesophageal cancer (correlation coefficient =0.5992). We suggest that improvement of well system for drinking water quality should be an effective measure for esophageal cancer prevention and control in rural areas.

    Full Text Available INTRODUCTION: In Mexico, breast cancer (BC is one of the main causes of cancer deaths in women, with increasing incidence and mortality in recent years. Therefore, the aim of the study is identify possible risk factors related to BC. METHODS: An epidemiological study of hospital cases of BC and controls with cervical uterine cancer (CUCA was carried out at eight third level concentration hospitals in Mexico City. The total of 353 incident cases of BC and 630 controls with CUCA were identified among women younger than 75 years who had been residents of the metropolitan area of Mexico City for at least one year. Diagnosis was confirmed histologically in both groups. Variables were analyzed according to biological and statistical plausibility criteria. Univariate, bivariate and multivariate analyses were carried out. Cases and controls were stratified according to the menopausal hormonal status (pre and post menopause. RESULTS: The factors associated with BC were: higher socioeconomic level (OR= 2.77; 95%CI = 1.77 - 4.35; early menarche (OR= 1.32; 95%CI= 0.88 - 2.00; old age at first pregnancy (>31 years: OR= 5.49; 95%CI= 2.16 - 13.98 and a family history of BC (OR= 4.76; 95% CI= 2.10 - 10.79. In contrast, an increase in the duration of the breastfeeding period was a protective factor (>25 months: OR= 0.38; 95%CI= 0.20 - 0.70. CONCLUSIONS: This study contributes to the identification of risk factors for BC described in the international literature, in the population of Mexican women. Breastfeeding appears to play an important role in protecting women from BC. Because of changes in women`s lifestyles, lactation is decreasing in Mexico, and young women tend not to breastfeed or to shorten the duration of lactation.

    Full Text Available Introduction. High values of standardized mortality and morbidity rates of standardized cancer mortality in Serbia, especially colorectal, cervical and breast cancer led to creation of national programs for their early detection and engagement of the international support for their implementation. Objective. Assessment of required resources (time, personnel, financial to implement the National program for screening of breast cancer in the Republic of Serbia. Methods. Three possible scenarios have been prepared (optimistic, realistic and pessimistic based on the expected coverage by screening of women aged 45 to 69 years, and time, personnel and financial feasibility estimates were made for a two-year screening cycle. Results. Time aspect of feasibility even under conditions of “relaxation” of the assumption on the number of working days during the year did not question feasibility of any of the scenarios. Personnel feasibility is only possible in the pessimistic scenario, while the financial feasibility only makes sense in optimistic scenario as the least unfavorable solution due to economies of scale. Conclusion. Establishment of the initial base of skilled radiologists and radiology technicians and the system for their continuous medical education as well as allocation of specific MoH budget line for screening program expenditures, along with donated mammographs and good organization and coordination, may provide unobstructed implementation of the National program for early detection of breast cancer in the Republic of Serbia.

    2009-09-01

    Full Text Available Abstract Background In this article, we describe the National Cancer Institute (NCI Community Cancer Centers Program (NCCCP pilot and the evaluation designed to assess its role, function, and relevance to the NCI's research mission. In doing so, we describe the evolution of and rationale for the NCCCP concept, participating sites' characteristics, its multi-faceted aims to enhance clinical research and quality of care in community settings, and the role of strategic partnerships, both within and outside of the NCCCP network, in achieving program objectives. Discussion The evaluation of the NCCCP is conceptualized as a mixed method multi-layered assessment of organizational innovation and performance which includes mapping the evolution of site development as a means of understanding the inter- and intra-organizational change in the pilot, and the application of specific evaluation metrics for assessing the implementation, operations, and performance of the NCCCP pilot. The assessment of the cost of the pilot as an additional means of informing the longer-term feasibility and sustainability of the program is also discussed. Summary The NCCCP is a major systems-level set of organizational innovations to enhance clinical research and care delivery in diverse communities across the United States. Assessment of the extent to which the program achieves its aims will depend on a full understanding of how individual, organizational, and environmental factors align (or fail to align to achieve these improvements, and at what cost.

    Bauer, Frank H.; Downing, John P.; Thorpe, Christopher J.

    1990-01-01

    Structural finite element models are often too large to be used in the design and analysis of control systems. Model reduction techniques must be applied to reduce the structural model to manageable size. In the past, engineers either performed the model order reduction by hand or used distinct computer programs to retrieve the data, to perform the significance analysis and to reduce the order of the model. To expedite this process, the latest version of INCA has been expanded to include an interactive graphical structural mode significance and model order reduction capability.

    Despite the recent acquisition of significant quantities of computed radiography CR equipment for mammography, Mexican regulations do not specify the performance requirements for digital systems such as those of CR type. The design of a quality control program QCP specific for CR mammography systems was thus considered relevant. International protocols were taken as reference to define tests, procedures and acceptance criteria. The designed QCP was applied in three CR mammography facilities. Important deficiencies in spatial resolution, noise, image receptor homogeneity, artifacts and breast thickness compensation were detected.

    The aim of the present study was to review the National Colorectal Cancer Screening Program (the Program) in Lithuania according to the criteria set by the European Union. In Lithuania, screening services are provided free of charge to the population. The National Health Insurance Fund (NHIF) reimburses the institutions for performing each service; each procedure within the Program has its own administrative code. All the information about the performance of the Program is collected in one institution - the NHIF. The results of the Program were retrieved from the database of NHIF from the start of the Program from 1 July 2009 to 1 July 2012. Descriptive analysis of epidemiological indicators was carried out. Results were compared with the references in the guidelines of the European Union for quality assurance in colorectal cancer (CRC) screening and diagnosis. Information service [which involves fecal immunochemical test (FIT)] was provided to 271,396 of 890,309 50-74-year-old residents. The screening uptake was 46.0% over 3 years. During this period, 19,455 (7.2%) FITs were positive and 251,941 (92.8%) FITs were negative. Referral for colonoscopy was performed in 10,190 (52.4%) patients. Colonoscopy was performed in 12,864 (66.1%) patients. Colonoscopy did not indicate any pathological findings in 8613 (67.0%) patients. Biopsies were performed in 4251 (33.0%) patients. The rate of high-grade neoplasia reported by pathologists was 3.9%; the rate of cancer was 3.1% of all colonoscopies. The rate of CRC detected by the Program was 0.2%. The CRC screening program in Lithuania meets most of the requirements for standardized CRC screening programs. The invitation coverage and rate of referral for colonoscopy after positive FIT should be improved.

    Full Text Available The Centers for Disease Prevention and Control’s National Comprehensive Cancer Control Program oversees Comprehensive Cancer Control (CCC programs designed to develop and implement CCC plans via CCC coalitions, alliances or consortia of program stakeholders. We reviewed 40 up-to-date plans for states and the District of Columbia in order to assess how capacity building and sustainability, two evidence-based practices necessary for organizational readiness, positive growth, and maintenance are addressed. We employed an electronic key word search, supplemented by full text reviews of each plan to complete a content analysis of the CCC plans. Capacity is explicitly addressed in just over half of the plans (53%, generally from a conceptual point of view, with few specifics as to how capacity will be developed or enhanced. Roles and responsibilities, timelines for action, and measurements for evaluation of capacity building are infrequently mentioned. Almost all (92% of the 40 up-to-date plans address sustainability on at least a cursory level, through efforts aimed at funding or seeking funding, policy initiatives and/or partnership development. However, few details as to how these strategies will be implemented are found in the plans. We present the Texas plan as a case study offering detailed insight into how one plan incorporated capacity building and sustainability into its development and implementation. Training, technical assistance, templates and tools may help CCC Coalition members address capacity and sustainability in future planning efforts and assure the inclusion of capacity building and sustainability approaches in CCC plans at both the state, tribal, territorial and jurisdiction levels.

    Full Text Available Physicians and health care organizations that provide services to low-income patients are valuable partners in improving health care access for the uninsured and medically underserved. In this pilot study, we explored physicians' needs and factors for satisfaction in the Women's Health Connection (WHC, a breast and cervical cancer-screening program for low-income women in Nevada. Of the 126 physicians in the WHC program, 50 physicians completed a needs-and-satisfaction questionnaire. Survey data were subjected to factor analysis using Varimax rotation. The results yielded three components, which accounted for 65% of the variance. The three components or dimensions for physician satisfaction were: (1 appropriate administrative support and documentation, (2 availability of support for medical management, and (3 timeliness of diagnostic reports. Amount of reimbursement was not a significant factor. The respondents serving in this cancer prevention program for low-income women were satisfied in their involvement in the program. Further attention should be given on the identified issues for satisfaction among physicians, which could lead to quality improvement and serve as a model for other programs that serve low-income patients in cancer prevention.

    The purpose of this study is to reveal the different risk factors related to this cancer particularly that there is no agreement about which factors affect the risk. A fishing expedition hospital based case control study was carried out. Cases and controls were identified from the Urology Department of Alexandria Main University Hospital, 2004. All cases diagnosed as having the tumor were included in the case series. For each case the second subject proved to have a negative pathological examination was included in the control group (50).Data collection was carried out blindly using a structured interview schedule. Analysis was applied using Chi-square test, Fisher exact and Student's t-test. Odds Ratios and 95% Confidence Intervals were calculated. Results indicated that regular consumption of sausages was greater among cases than controls (X(2)= 10.19, p= 0.001 and an odds ratio of 5.92 (CI: 1.69-25.99). Also more cases claimed consuming regularly butter and natural ghee than controls (X(2)= 5.47, p= 0.019). The estimate risk was as high as 2.79 (Cl: 1.07-7.33). However regular consumption of vegetables was more encountered among controls than cases (X(2) = 5.005, p= 0.025 where the odds ratio was 0.19 (Cl: 0.02-1.01). Moreover the multiple regression analysis confirmed the results obtained from univariate analysis. The consistency of results of current work as regards sausages and butter with several other research works can support the identification of these specific possible risk factors. Also other research workers pointed out to the protective effect of vegetables. However further research is needed to address other risk factors.

    Full Text Available Abstract Background Quality of life (QOL issues are of interest in cancer because effective methods of treatment and detection have led to an increase in the number of long-term survivors. The objectives of the study were: to assess the subjective QOL of stable Sudanese women cancer outpatients and their family caregivers, using the WHO 26-item QOL Instrument; compare with matched general population groups, as well as diabetic and psychiatric patient groups; examine patient-caregiver concordance in ratings; and assess the variables associated with their QOL, with a view to identifying factors that can enhance quality of care. Methods Responses of oncology outpatients with breast cancer (117, cervical cancer (46 and ovarian cancer (18 (aged 44.6, SD 11.5 were compared with those of their family caregivers and matched general population groups. Data were analyzed by univariate and multivariate statistics. Results The cancer groups had similar QOL domain scores, which were significantly lower than those of their caregivers, but higher than the control group as well as those of psychiatric and diabetic patients studied previously. Patients who were married, with higher education, better employment, and with longer duration of illness had higher QOL. Patients on radiotherapy and their caregivers had higher QOL scores. Correlations between patient's ratings and caregiver impression of patient's QOL were high. Caregiver impression was a significant predictor of patient's and caregiver's QOL. Other predictors for the patient were: currently feeling sick and duration of illness; for the caregiver: feeling sick, relationship to patient, and age. Conclusion Cancer patients in stable condition and with psychosocial support can hope to enjoy good QOL with treatment. The findings constitute an evidence base for the country's cancer care program, to boost national health education about prognosis in cancer. Families living with women cancer patients are

    The need to familiarize medical students and graduate health professional students with research training opportunities that cultivate the appeal of research careers is vital to the future of research. Comprehensive evaluation of a cancer research training program can be achieved through longitudinal tracking of program alumni to assess the program's impact on each participant's career path and professional achievements. With advances in technology and smarter means of communication, effective ways to track alumni have changed. In order to collect data on the career outcomes and achievements of nearly 500 short-term cancer research training program alumni from 1999-2013, we sought to contact each alumnus to request completion of a survey instrument online, or by means of a telephone interview. The effectiveness of each contact method that we used was quantified according to ease of use and time required. The most reliable source of contact information for tracking alumni from the early years of the program was previous tracking results, and for alumni from the later years, the most important source of contact information was university alumni records that provided email addresses and telephone numbers. Personal contacts with former preceptors were sometimes helpful, as were generic search engines and people search engines. Social networking was of little value for most searches. Using information from two or more sources in combination was most effective in tracking alumni. These results provide insights and tools for other research training programs that wish to track their alumni for long-term program evaluation.

    Purpose: Cancer-related fatigue is frequently experienced by patients during and after therapy. The present study was conducted to assess the impact of energy conservation strategies and health promotion in breast cancer survivors. Methods: A randomized controlled trial was carried out to compare the intervention effect (n=69.0) with controls (n=66.0) based on routine oncology ward care. The intervention was five weekly sessions for groups of 6-8 breast cancer survivors. Data on fatigue and health promotion lifestyle were obtained before and after completion the intervention and then 8 weeks later for analysis of variance (ANOVA) with repeated measures. Results: Our findings showed cancer-related fatigue to be reduced in the intervention group from pre- to post-intervention, and this persisted over the 8-weeks follow-up period (F = 69.8, p<0.001). All subscales of the cancer fatigue scale demonstrated statistically significant effects with partial eta-squared values ranging from 0.15 (the smallest effect in cognitive fatigue) to 0.21 (the largest for affective fatigue). Changes in the health promotion life style indicated a significant promotion from pre- to post-intervention, and this again continued after 8-weeks follow-up (F = 41.6, p < 0.001). All six domains of a health promoting life style featured significantly elevated values, the largest effect being seen in the interpersonal relations subscale (F=57.7, partial η2=0.21, p<0.001) followed by physical activity (F=51.9, partial η2=0.18, p<0.001). Conclusions: The program was effective in decreasing cancer related fatigue and promoting a healthy lifestyle.

  10. Re-programming tumour cell metabolism to treat cancer: no lone target for lonidamine

    Tumour cell metabolism is very different from normal cell metabolism; cancer cells re-programme the metabolic pathways that occur in normal cells in such a manner that it optimizes their proliferation, growth and survival. Although this metabolic re-programming obviously operates to the advantage of the tumour, it also offers unique opportunities for effective cancer therapy. Molecules that target the tumour cell-specific metabolic pathways have potential as novel anti-cancer drugs. Lonidamine belongs to this group of molecules and is already in use in some countries for cancer treatment. It has been known for a long time that lonidamine interferes with energy production in tumour cells by inhibiting hexokinase II (HKII), a glycolytic enzyme. However, subsequent studies have uncovered additional pharmacological targets for the drug, which include the electron transport chain and the mitochondrial permeability transition pore, thus expanding the pharmacological effects of the drug on tumour cell metabolism. A study by Nancolas et al. in a recent issue of the Biochemical Journal identifies two additional new targets for lonidamine: the pyruvate transporter in the mitochondria and the H+-coupled monocarboxylate transporters in the plasma membrane (PM). It is thus becoming increasingly apparent that the anti-cancer effects of lonidamine do not occur through a single target; the drug works at multiple sites. Irrespective of the molecular targets, what lonidamine does in the end is to undo what the tumour cells have done in terms of re-programming cellular metabolism and mitochondrial function.

    Full Text Available Parisa Momtaz,1,2 Michael A Postow1,2 1Department of Medicine, Memorial Sloan Kettering Cancer Center, New York, NY, USA; 2Weill Cornell Medical College, New York, NY, USA Abstract: T-lymphocytes have the potential to recognize cancer antigens as foreign and therefore eliminate them. However, immune checkpoints such as cytotoxic T-lymphocyte-associated antigen (CTLA-4 and programmed cell death (PD-1 receptor and its ligands (PD-L1, PD-L2 suppress the activity of T-lymphocytes. Advances in the understanding of immunology and its role in cancer have led to the development of immune checkpoint inhibitors that block CTLA-4 and PD-1 and result in durable responses in patients with a wide range of cancers. PD-1 and PD-L1 inhibitors are currently in many stages of clinical investigation, and the anti-PD-1 antibody, pembrolizumab, was recently approved by the US Food and Drug Administration. Many questions remain to be answered, such as the optimal administration schedule, biomarkers that associate with benefit, and potential for use of PD-1 agents in combination approaches. Nonetheless, immunotherapy with PD-1 blocking antibodies is now becoming an integral part in the management of cancer.

    We surveyed speech language pathology (SLP) programs for head and neck cancer (HNC) training. Program directors of 242 American Speech-Language-Hearing Association accredited masters programs for SLP were contacted regarding curricular HNC material. Directors (n = 120) responded online: six included a required course in HNC, and all but two programs with no required HNC course included HNC topics in other required courses. Thirty-two programs were affiliated with a medical center and/or a teaching hospital. Programs that offered either a required course in HNC or elective courses on HNC were more likely to be affiliated with a medical center and/or a teaching hospital than programs that did not offer a required course in HNC (P = 0.043) or elective courses on HNC (P = 0.007), respectively. Few programs offer a required HNC course but most programs integrate HNC content into the required coursework. Potential strategies to incorporate HNC exposure into formal SLP programs are identified.

    Only limited data is available on the relationship between family history of laryngeal and other neoplasms and laryngeal cancer risk. We investigated the issue using data from a multicentre case-control study conducted in Italy and Switzerland between 1992 and 2009 including 852 cases with histologically confirmed laryngeal cancer and 1970 controls admitted to hospital for acute, non neoplastic conditions. Unconditional logistic regression models adjusted for age, sex, study center, education, tobacco smoking, alcohol drinking and number of siblings were used to estimate the odds ratios (ORs) of laryngeal cancer. The multivariate OR was 2.8 (95% confidence interval [CI], 1.5-5.3) in subjects reporting a first-degree relative with laryngeal cancer, as compared to subjects with no family history. The OR was higher when the relative was diagnosed before 60 years of age (OR = 3.5, 95% CI 1.4-8.8). As compared to subjects without family history, non-smokers, and moderate drinkers, the OR was 37.1 (95% CI 9.9-139.4) for current smokers, heavy drinkers, with family history of laryngeal cancer. Family history of colorectal (OR = 1.5, 95% CI 1.0-2.3) and kidney (OR = 3.8, 95% CI 1.2-12.1) cancer were also associated to an increased risk of laryngeal cancer, while no significant increase in risk was found for family history of cancer at all sites, excluding the larynx (OR = 1.1).

    1991-01-01

    The population explosion has been abating since the 2nd half of the 1960s. The birth rate of the 3rd World dropped from 45/1000 during 1950-55 to 31/1000 during 1985-90. From the 1st half of the 1960s to the 1st half of the 1980s the total fertility of such countries dropped from 6.1 to 4.2 children/woman. In Taiwan, Singapore, Hong Kong, South Korea, and Malaysia living standards improved as a result of industrialization, and fertility decreased significantly. In Sri Lanka, China, North Vietnam, and Thailand the drop of fertility is explained by cultural and religious factors. In 1982 about 78% of the population of developing countries lived in 39 states that followed an official policy aimed at reducing the population. Another 16% lived in countries supporting the concept of a desired family size. However, World Bank data showed that in the mid-1980s in 27 developing countries no state family planning (FP) programs existed. India adopted an official FP program in 1952, Pakistan followed suit in 1960, South Korea in 1961, and China in 1962. In Latin America a split policy manifested itself: in Brazil birth control was rejected, only Colombia had a FP policy. In 1986 the governments of 68 of 131 developing countries representing 3.1 billion people considered the number of children per woman too high. 31 of these countries followed concrete population control policies. On the other hand, in 1986 24 countries of Africa with 40% of the continent's population took no measures to influence population growth. In Latin America and the Caribbean 18 of 33 countries were idle, except for Mexico that had a massive state FP program. These programs also improve maternal and child health with birth spacing of at least 2 years, and the prevention of pregnancies of too young women or those over 40. The evaluation of rapidly spreading FP programs in the 1970s was carried out by the World Fertility Survey in 41 countries. The impact of FP programs was more substantial than

    The present study was aimed at assessing the health consequences of the presence of radon in Quebec homes and the possible impact of various screening programs on lung cancer mortality. Lung cancer risk due to this radioactive gas was estimated according to the cancer risk model developed by the Sixth Committee on Biological Effects of Ionizing Radiations. Objective data on residential radon exposure, population mobility, and tobacco use in the study population were integrated into a Monte-Carlo-type model. Participation rates to radon screening programs were estimated from published data. According to the model used, approximately 10% of deaths due to lung cancer are attributable to residential radon exposure on a yearly basis in Quebec. In the long term, the promotion of a universal screening program would prevent less than one death/year on a province-wide scale (0.8 case; IC 99%: -3.6 to 5.2 cases/year), for an overall reduction of 0.19% in radon-related mortality. Reductions in mortality due to radon by (1) the implementation of a targeted screening program in the region with the highest concentrations, (2) the promotion of screening on a local basis with financial support, or (3) the realization of systematic investigations in primary and secondary schools would increase to 1%, 14%, and 16.4%, respectively, in the each of the populations targeted by these scenarios. Other than the battle against tobacco use, radon screening in public buildings thus currently appears as the most promising screening policy for reducing radon-related lung cancer.

    Full Text Available Introduction: As one of the most common cancers among head and neck malignancies, cancer of the oral cavity probably has some variations in countries with a high prevalence of esophageal cancer.  Materials and Methods: Patients with oral cavity cancer who were treated at two tertiary referral centers from January 1999 to January 2009 were included in this study. In addition to demographic data, information regarding personal and family history of head and neck cancer, use of dentures, presence of immune deficiency, consumption of alcohol, and incidence of cigarette smoking was collected. Additionally, a history of opium usage was obtained from the participants in this study. Moreover, an appropriately matched control group was selected for comparisons between the risk factors.   Results: A total of 557 patients were entered into this study over a 10-year period, of whom 219 (39.3% were female and the remaining 338 (60.7% were male. The tongue was the most common site of cancer and 9% of the patients had a history of opium abuse, but more than half of the patients did not have any recognized risk factors. The incidence and stage of cancer had a significant relationship with cigarette smoking (P= 0.013.   Conclusion: Tongue cancer in non-smokers is the predominant pattern of oral cavity cancer in Iran.

  20. Use of a general control simulation program to evaluate HVAC control stability

    1987-08-01

    A general process engineering simulation program for a microcomputer is used to evaluate the response of a cooling system to changes in load, set point, and controller tuning parameters to better understand the control stability of a supply air cooling system used in the Mobile Windows Thermal Test (MoWiTT) Facility. A detailed system model is built out of standard components and is used to plot the steady state performance under different operating conditions. The response of the cooling coil output depends strongly on the transport delays. For a system with a linear control valve, the process gain of the cooling coil increases rapidly as the valve flow fraction decreases. A system which is stable at mid-range is shown to become marginally unstable at the low end of the control range. The application of both an equal percentage valve and reheat are shown to improve the control response of the system under low cooling load conditions.

    Background The value of community-based cancer research has long been recognized. In addition to the National Cancer Institute’s Community Clinical and Minority-Based Oncology Programs established in 1983, and 1991 respectively, the National Cancer Institute established the National Cancer Institute Community Cancer Centers Program in 2007 with an aim of enhancing access to high-quality cancer care and clinical research in the community setting where most cancer patients receive their treatment. This article discusses strategies utilized by the National Cancer Institute Community Cancer Centers Program to build research capacity and create a more entrenched culture of research at the community hospitals participating in the program over a 7-year period. Methods To facilitate development of a research culture at the community hospitals, the National Cancer Institute Community Cancer Centers Program required leadership or chief executive officer engagement; utilized a collaborative learning structure where best practices, successes, and challenges could be shared; promoted site-to-site mentoring to foster faster learning within and between sites; required research program assessments that spanned clinical trial portfolio, accrual barriers, and outreach; increased identification and use of metrics; and, finally, encouraged research team engagement across hospital departments (navigation, multidisciplinary care, pathology, and disparities) to replace the traditionally siloed approach to clinical trials. Limitations The health-care environment is rapidly changing while complexity in research increases. Successful research efforts are impacted by numerous factors (e.g. institutional review board reviews, physician interest, and trial availability). The National Cancer Institute Community Cancer Centers Program sites, as program participants, had access to the required resources and support to develop and implement the strategies described. Metrics are an important

    In this case-control study we determined whether dietary differences underlie some of the ethnic and sex differences in US lung cancer rates. We examined the relationship between diet and lung cancer development in 137 lung cancer cases (93 African Americans and 44 Mexican Americans) and 187 controls (78 African Americans and 109 Mexican Americans). Cases reported a higher daily mean total fat intake (p fruits (p = 0.02). Ethnic differences in diet were also observed: Mexican Americans consumed less total fat (p fruits (p lung cancer risk (p fruit consumption and lung cancer risk (p = 0.05). In conclusion, our findings support the hypothesis that diet, particularly high fat consumption and low fruit and vegetable consumption, contributes (independent of cigarette smoking) to the excess lung cancer risk in African-American men, who have the highest lung cancer rates in the United States.

    Under the Atoms for Peace program, Turkey received a one MWt swimming pool reactor in 1962 that initiated a health physics program for the reactor and a Radiation Control Program (RCP) for the country's use of ionizing radiation. Today, over 13,000 radiation workers, concentrated in the medical field, provide improved medical care with 6,200 x-ray units, including 494 CAT scanners, 222 radioimmunoassay (RIA) labs and 42 radiotherapy centers. Industry has a large stake in the safe use of ionizing radiation with over 1,200 x-ray and gamma radiography and fluoroscopic units, 2,500 gauges in automated process control and five irradiators. A 48-person RCP staff oversees this expanded radiation use. One incident involving a spent 3.3 TBq (88 Ci) 60Co source resulted in 10 overexposures but no fatalities. Taiwan received a 1.6 MWt swimming pool reactor in 1961 and rapidly applied nuclear technology to the medical and industrial fields. Today, there are approximately 24,000 licensed radiation workers in nuclear power field, industry, medicine and academia. Four BWRs and two PWRs supply about 25% of the island's electrical power needs. One traumatic event galvanized the RCP when an undetermined amount of 60Co was accidentally incorporated into reinforcing bars, which in turn were incorporated into residential and commercial buildings. Public exposures were estimated to range up to 15 mSv (1.3 rem) per annum. There were no reported ill effects, except possibly psychological, to date. The RCP now has instituted stringent control measures to ensure radiation-free dwellings and work places. Albania's RCP is described as it evolved since 1972. Regulations were promulgated which followed the IAEA Basic Safety Standards of that era. With 525 licenses and 600 radiation workers, the problem was not in the regulations per se but in their enforcement. The IAEA helped to upgrade the RCP as the economy evolved from one that was centrally planned economy to a free market economy. As this

    Full Text Available Abstract Introduction The raw incidence of cancer of the uterine cervix is Spain is 7,8 per 100.000 inhabitants (adjusted incidence is 5.6. The incidence of this tumor is still low, but a steady increase has been seen, probably related to increasing risk factors. Aim To determine the frequency of infection by different types of human papillomavirus (HPV in Papanicolau smears from women with and without cancer of the uterine cervix in Spain. Patients and methods A case-control study was performed in women with and without cervical cancer from Zaragoza, Spain. Pap smears from 600 cases (540 women with cervical intraepithelial neoplasms (CIN and 60 with invasive cancer and 1200 controls (women without those lesions were tested by polymerase chain reaction (PCR and typed by oligonucleotide microarray-based detection. Results HPV was detected in 93.3% of all samples with invasive cancer versus 17.5% of controls. OR for invasive cancer was 55 (95% CI 21.5–140,5. Statistically significant associations were also found for different grades of cervical dysplasia. Conclusion The strong association found between HPV infection, specifically types 16 and 18 and cancer of the uterine cervix in Zaragoza, Spain, stresses the importance of ongoing efforts to institute a vaccine program with recently approved HPV vaccines in order to prevent cervical cancer in this population.

    Cancer is a major health problem in both high income and middle-to-low income countries, and is the second leading cause of death in the world. Although more than a third of cancer could be prevented and another third could be cured if diagnosed early, it remains a huge challenge to health-care systems worldwide. Despite substantial improvements in health services some of the countries in the Gulf region, the burden of non-communicable diseases is a major threat, primarily due to the rapid socioeconomic shifts that have led to unfavourable changes in lifestyle such as increased tobacco use, decreased physical activity, and consumption of unhealthy food. In the Gulf Cooperation Council states (United Arab Emirates, Bahrain, Saudi Arabia, Oman, Qatar, and Kuwait), advanced breast cancer, colorectal cancer, leukaemia, thyroid cancer, and non-Hodgkin lymphomas are the most common cancers affecting younger populations compared with other countries. By contrast with cancer prevalence in developed countries, prostate, lung, and cervical cancers are not among the most common cancers in the Gulf region. In view of the increased cost of cancer management worldwide, integrated approaches between primary, secondary, and tertiary health-care systems with special focus on prevention and early detection is an essential step in the countries' efforts in the fight against cancer.

    Full Text Available This research was conducted to evaluate (1 rice tolerance to saflufenacil applied preemergence (PRE and postemergence (POST and (2 the combination of saflufenacil and clomazone in light-textured soils. No injury from PRE application of saflufenacil was observed in 2009, and minimal injury for saflufenacil alone was observed in 2010. Injury as high as 68% was observed with combinations of 505 g ha−1 of clomazone applied PRE and 50 g ha−1 of saflufenacil applied POST in 2009 early evaluations. No interaction between clomazone and POST saflufenacil rates was observed in 2010. Rice injury intensified with increasing rates of saflufenacil applied POST. However, rice recovered with time for herbicide treatments applied PRE and POST in both years. Consequently, rice yield was not affected by any of the saflufenacil rates applied either PRE or POST in a clomazone weed control program.

    2016-08-01

    Full Text Available Oral cancer rates have been increasing. There are several ongoing studies on this subject that specifically focus on the risk factors for this type of cancer. Addressing this problem holistically will allow analyzing this phenomenon using various approaches. For such reasons, we conducted a review of research papers published in electronic journals in SciELO and PubMed databases in order to demonstrate the contribution of the Oral Cancer Screening Program to Cuban public health and its interrelation with science, technology, and society. The assumed starting point allows stating that the science, technology and society approach is not only a field of study concerned with the complex interrelationships between science, technology, and the societies in which they develop. In addition, this approach is related to all social areas. Therefore, it is not just a matter of thought or study; it is, above all, a practical-existential problem.

  9. The facilities and challenges for cancer control in India.

    India is a vast subcontinent with 845 million peoples occupying 2.5% of land mass of the earth, but carrying 15% of the world population. It is a multiracial society with widely varying cultures, habits, languages and many different ethnic groups. The pattern of cancer, therefore, mainly depends on their habits and life styles apart from other variations. Head, Neck & Esophagus cancers in the male and cervix and breast cancers in the females are the main cancers. All together they form nearly 60% of all cancers. The incidence rates are around 90/100,000 though this is an underestimate as cancer is not a notifiable disease in India. It is estimated that by the year 2,000 there will be six million cancer patients in India at any given time with nearly 2 million new patients annually. The over-all facilities for cancer treatment vary widely from metropolitan cities to rural areas where 70% of the Indian population lives. In major cities, good to excellent treatment facilities exist in comprehensive cancer centres--yet in the rural setting the facilities are sketchy at best or non-existent at worst. The Government of India in its national cancer policy has recognized regional cancer centres and consolidated other existing centres. There are 10 regional cancer centres thus identified, each one at a different level of development. For optimal requirements at least 600 teletherapy units, (existing 150--not always functional) 100 departments of surgical oncology and an equal number of medical oncology divisions are needed (existing 20). The demand for cancer treatment facilities are, therefore, very high with poor available facility. Nearly 50% of patients present late for treatment and therefore appropriate education in prevention and early diagnosis are important factors. The Government of India through Ministry of Health has identified cancer as a major health problem by the year 2,000 and hence planning by the National Cancer Plan is operative in many States. Major

    Lymphedema, pain, and range of motion restrictions after breast cancer remain underexplored, and few interventions have been developed for these women. Together with a yoga instructor, our interdisciplinary research team developed a yoga program for women with lymphedema after breast cancer (n = 13). Qualitative interviews and participants' journals show that there were a number of benefits to the yoga program. Themes outlining these are (1) understanding arm morbidity; (2) becoming aware of posture; and (3) countering fatigue. More surprisingly, perhaps, the participants also described the ways in which yoga furthered their understandings of loss associated with disability, the fourth theme, and showed that yoga enhanced their experiences of embodiment, the final theme. Finally, we assert that our research demonstrates the potential for qualitative research connected to the evaluation of interventions and that it demonstrates the blurring of traditional boundaries between interventions and data collection.

    Be The Match® Patient and Health Professional Services (PHPS) supports patients undergoing hematopoietic cell transplant (HCT) and caregivers by providing educational programs and resources. HCT is a potentially curative therapy for blood cancers such as leukemia and lymphoma. To help meet the increasing demand for support services, PHPS implemented a multipronged plan to build and sustain the organization's capacity to conduct evaluation of its programs and resources. To do so, PHPS created and operationalized an internal evaluation model, developed customized resources to help stakeholders incorporate evaluation in program planning, and implemented utilization-focused evaluation for quality improvement. Formal mentorship was also critical in the development of an evidence-based, customized model and navigating inherent challenges throughout the process. Our model can serve as a guide for evaluators on establishing and operationalizing an internal evaluation program. Ultimately, we seek to improve support and education services from the time of diagnosis through survivorship.

    Investigations of spiritual interventions for cancer patients are disproportionately few compared to the reported importance of religion to Americans. We report on the implementation and evaluation of a spiritual, community-based intervention developed with interdenominational community clergy. Approximately 1200 people attended a total of 3 gatherings: 2 at Roman Catholic and another at a Protestant Church. Respondents to questionnaires evaluating attendee characteristics and satisfaction (n = 209) were predominantly women (85%); 50% were patients and 45% were aged 60 years and older. Men were more likely to be currently under treatment for cancer, while women were more likely to be past patients or friends. Fewer than 2% felt anger or anxiety; attendees felt the service was very (90%) or somewhat (9.5%) helpful and expressed appreciation for cancer program clinician attendance and for hospital sponsorship of the event. Components in order of preference were prayer, music, Scripture, and litany. Logistic regression models reveal that music was most appreciated by previously treated patients, and prayer by currently treated patients. Secular healthcare systems can offer a religious service that comforts and links attendees to a broader community, including clergy and cancer program clinicians. Surveys can identify service components that appeal to differing groups and can facilitate service development.

    Experimental studies have indicated that disulfiram (Antabuse) has antineoplastic effects against melanoma, breast, and prostate cancer. To explore this hypothesis, we examined the association between disulfiram use and these cancers in a nationwide register-based case-control study nested within ever-users (≥one prescription) of disulfiram. Cases were all Danish individuals with a histologically verified first-time diagnosis of malignant melanoma, breast, or prostate cancer during 2000-2009. For each case, we selected four cancer-free controls matched for age, sex, and year of first disulfiram prescription using risk set sampling. Similarly, for secondary analyses, we selected case-control populations for selected tobacco-related and alcohol-related cancer types, that is, cancers of the buccal cavity, liver, lung, and colorectal cancer. Disulfiram use 1 year before cancer diagnosis and the corresponding date for controls were disregarded. We estimated crude and adjusted odds ratios and 95% confidence intervals (CI) for cancer associated with long-term (≥500 daily defined doses) versus one-time (one prescription) use of disulfiram. Among 53 856 disulfiram users, we identified 166, 644, and 464 cases, respectively, of melanoma, breast, or prostate cancer. Adjusted odds ratios for melanoma, breast, or prostate cancer associated with long-term disulfiram use were 1.04 (95% CI: 0.60-1.78), 0.92 (95% CI: 0.70-1.22), and 0.77 (95% CI: 0.56-1.06), respectively. For prostate cancer, dose-response analyses showed a further risk reduction with the highest cumulative dose level of disulfiram; however, the test for trend did not reach statistical significance. Our study provides some epidemiological support for a protective effect of disulfiram against prostate and breast cancer.

    The anatomy, physiology, and biochemistry of the human skin have been studied for a long time. A special interest has been shown in the water permeability of the premature infant's skin, which is known to be an important factor in the maintenance of a controlled water and heat balance. The rate of evaporative heat exchange between the skin surface of a very premature infant and the surrounding incubator air may be so high that evaporative heat loss alone may exceed the infant's total metabolic heat production. However, it has been demonstrated in several investigations published in recent years that basal evaporative water loss can be consistently reduced by increasing the ambient humidity. Nevertheless, the passive humidification system (water reservoir) used in most incubators cannot achieve high and steady humidity levels. In this paper, we propose an active humidification system. The algorithm is based on a combination of optimal control theory and dynamic programming approach. The relative-humidity (R.H.) regulation is performed in range of 35-90% at 33 degrees C with small oscillations (+/- 0.5% R.H.) around the reference value (i.e., prescribed R.H.).

    Full Text Available The aim was to illuminate the meaning of participating in support and rehabilitation programs described by people diagnosed with cancer. Nineteen persons were interviewed in focus groups and face-to-face. Data were analyzed with a qualitative phenomenological hermeneutical method for researching lived experiences. Interpretation proceeded through three phases: naïve reading, structural analysis, and comprehensive understanding. Three themes were disclosed: receiving support for recovery when being most vulnerable, recapturing capabilities through supportive activities, and searching to find stability and well-being in a changed life situation. Participating in the programs was an existential transition from living in an unpredictable situation that was turned into something meaningful. Recovery did not mean the return to a state of normality; rather, it meant a continuing recovery from cancer treatments and symptoms involving recapturing capabilities and searching for a balance in a forever changed life. This study provides new insights about the experiences of participating in cancer support and rehabilitation programs.

    In assessment of screening for cancer, no distinction is usually made between the sensitivity of the screening test (St) and the sensitivity of the screening program (Sp). This paper was aimed to distinguish meaning, method for assessment and interest for each of them, and to determine their relationship. Sensitivity of the screening program can be directly assessed with data from on-going trials whilst assessment of sensitivity of screening test requires modelisation techniques, especially for assessing the mean duration of the preclinical phase of cancer. Assuming an exponential distribution of this duration, lambda as the time parameter, a mathematical relation between St and Sp is suggested as follows: [formula: see text] with r being the interval between two screening tests. The implementation of this equation with data from a mass-screening program for colorectal cancer in the department of Calvados allowed us to investigate the influence of the mean preclinical phase and the interval between two screening tests on the value of the sensitivity of the screening procedure. Such a modelisation could be useful in the development of a rational screening policy.

    The molecular mechanisms underlying the aggressive behavior of MYCN driven neuroblastoma (NBL) is under intense investigation; however, little is known about the impact of this family of transcription factors on the splicing program. Here we used high-throughput RNA sequencing to systematically study the expression of RNA isoforms in stage 4 MYCN-amplified NBL, an aggressive subtype of metastatic NBL. We show that MYCN-amplified NBL tumors display a distinct gene splicing pattern affecting multiple cancer hallmark functions. Six splicing factors displayed unique differential expression patterns in MYCN-amplified tumors and cell lines, and the binding motifs for some of these splicing factors are significantly enriched in differentially-spliced genes. Direct binding of MYCN to promoter regions of the splicing factors PTBP1 and HNRNPA1 detected by ChIP-seq demonstrates that MYCN controls the splicing pattern by direct regulation of the expression of these key splicing factors. Furthermore, high expression of PTBP1 and HNRNPA1 was significantly associated with poor overall survival of stage4 NBL patients (p ≤ 0.05). Knocking down PTBP1, HNRNPA1 and their downstream target PKM2, an isoform of pro-tumor-growth, result in repressed growth of NBL cells. Therefore, our study reveals a novel role of MYCN in controlling global splicing program through regulation of splicing factors in addition to its well-known role in the transcription program. These findings suggest a therapeutically potential to target the key splicing factors or gene isoforms in high-risk NBL with MYCN-amplification.

    Full Text Available Abstract Background Currently 1 in 11 women over the age of 60 in Australia are diagnosed with breast cancer. Following treatment, most breast cancer patients are left with shoulder and arm impairments which can impact significantly on quality of life and interfere substantially with activities of daily living. The primary aim of the proposed study is to determine whether upper limb impairments can be prevented by undertaking an exercise program of prolonged stretching and resistance training, commencing soon after surgery. Methods/design We will recruit 180 women who have had surgery for early stage breast cancer to a multicenter single-blind randomized controlled trial. At 4 weeks post surgery, women will be randomly assigned to either an exercise group or a usual care (control group. Women allocated to the exercise group will perform exercises daily, and will be supervised once a week for 8 weeks. At the end of the 8 weeks, women will be given a home-based training program to continue indefinitely. Women in the usual care group will receive the same care as is now typically provided, i.e. a visit by the physiotherapist and occupational therapist while an inpatient, and receipt of pamphlets. All subjects will be assessed at baseline, 8 weeks, and 6 months later. The primary measure is arm symptoms, derived from a breast cancer specific questionnaire (BR23. In addition, range of motion, strength, swelling, pain and quality of life will be assessed. Discussion This study will determine whether exercise commencing soon after surgery can prevent secondary problems associated with treatment of breast cancer, and will thus provide the basis for successful rehabilitation and reduction in ongoing problems and health care use. Additionally, it will identify whether strengthening exercises reduce the incidence of arm swelling. Trial Registration The protocol for this study is registered with the Australian Clinical Trials Registry (ACTRN012606000050550.

    This paper reports the most cost-effective policy options to support and improve breast cancer control in Costa Rica and Mexico. Total costs and effects of breast cancer interventions were estimated using the health care perspective and WHO-CHOICE methodology. Effects were measured in disability-adjusted life years (DALYs) averted. Costs were assessed in 2009 United States Dollars (US$). To the extent available, analyses were based on locally obtained data. In Costa Rica, the current strategy of treating breast cancer in stages I to IV at a 80% coverage level seems to be the most cost-effective with an incremental cost-effectiveness ratio (ICER) of US$4,739 per DALY averted. At a coverage level of 95%, biennial clinical breast examination (CBE) screening could improve Costa Rica's population health twofold, and can still be considered very cost-effective (ICER US$5,964/DALY). For Mexico, our results indicate that at 95% coverage a mass-media awareness raising program (MAR) could be the most cost-effective (ICER US$5,021/DALY). If more resources are available in Mexico, biennial mammography screening for women 50-70 yrs (ICER US$12,718/DALY), adding trastuzumab (ICER US$13,994/DALY) or screening women 40-70 yrs biennially plus trastuzumab (ICER US$17,115/DALY) are less cost-effective options. We recommend both Costa Rica and Mexico to engage in MAR, CBE or mammography screening programs, depending on their budget. The results of this study should be interpreted with caution however, as the evidence on the intervention effectiveness is uncertain. Also, these programs require several organizational, budgetary and human resources, and the accessibility of breast cancer diagnostic, referral, treatment and palliative care facilities should be improved simultaneously. A gradual implementation of early detection programs should give the respective Ministries of Health the time to negotiate the required budget, train the required human resources and understand possible

    Activation of cellular stress response pathways to maintain metabolic homeostasis is emerging as a critical growth and survival mechanism in many cancers1. The pathogenesis of pancreatic ductal adenocarcinoma (PDA) requires high levels of autophagy2–4, a conserved self-degradative process5. However, the regulatory circuits that activate autophagy and reprogram PDA cell metabolism are unknown. We now show that autophagy induction in PDA occurs as part of a broader transcriptional program that coordinates activation of lysosome biogenesis and function, and nutrient scavenging, mediated by the MiT/TFE family transcription factors. In PDA cells, the MiT/TFE proteins6 – MITF, TFE3 and TFEB – are decoupled from regulatory mechanisms that control their cytoplasmic retention. Increased nuclear import in turn drives the expression of a coherent network of genes that induce high levels of lysosomal catabolic function essential for PDA growth. Unbiased global metabolite profiling reveals that MiT/TFE-dependent autophagy-lysosomal activation is specifically required to maintain intracellular amino acid (AA) pools. These results identify the MiT/TFE transcription factors as master regulators of metabolic reprogramming in pancreatic cancer and demonstrate activation of clearance pathways converging on the lysosome as a novel hallmark of aggressive malignancy.

    The stochastic optimal controller design for the nonlinear networked control system (NNCS) with uncertain system dynamics is a challenging problem due to the presence of both system nonlinearities and communication network imperfections, such as random delays and packet losses, which are not unknown a priori. In the recent literature, neuro dynamic programming (NDP) techniques, based on value and policy iterations, have been widely reported to solve the optimal control of general affine nonlinear systems. However, for realtime control, value and policy iterations-based methodology are not suitable and time-based NDP techniques are preferred. In addition, output feedback-based controller designs are preferred for implementation. Therefore, in this paper, a novel NNCS representation incorporating the system uncertainties and network imperfections is introduced first by using input and output measurements for facilitating output feedback. Then, an online neural network (NN) identifier is introduced to estimate the control coefficient matrix, which is subsequently utilized for the controller design. Subsequently, the critic and action NNs are employed along with the NN identifier to determine the forward-in-time, time-based stochastic optimal control of NNCS without using value and policy iterations. Here, the value function and control inputs are updated once a sampling instant. By using novel NN weight update laws, Lyapunov theory is used to show that all the closed-loop signals and NN weights are uniformly ultimately bounded in the mean while the approximated control input converges close to its target value with time. Simulation results are included to show the effectiveness of the proposed scheme.

    Adding aromatase inhibitors (AIs) to adjuvant treatment of postmenopausal women with hormone-receptor-positive breast cancer significantly reduces cancer recurrence. A common side effect of AIs is noninflammatory joint pain and stiffness (arthralgia) similar to arthritis symptoms. An evidence-based walking program developed by the Arthritis Foundation - Walk With Ease (WWE) - reduces arthritis-related joint symptoms. We hypothesized that WWE may also reduce AI-associated arthralgia. However, the potential for different barriers and facilitators to physical activity for these 2 patient populations suggested a need to adapt WWE before testing it with breast cancer survivors. We conducted qualitative research with 46 breast cancer survivors to explore program modification and inform the development of materials for an adapted program (Walk With Ease-Breast Cancer). Our process parallels the National Cancer Institute's Research-Tested Intervention Programs (RTIPs) guidelines for adapting evidence-based programs for cancer populations. Findings resulted in a customized 8-page brochure to supplement existing WWE materials.

    Full Text Available In some Chilean cities, levels of arsenic (As in drinking water reached 800 µg/L between 1950 and 1970, while current levels are 40 µg/L. To evaluate the causal role of this exposure in lung and bladder cancers, we conducted a case-control study in Regions I, II, and III of the country. From 1994 to 1996, cases diagnosed as lung cancer and two hospital controls were entered in the study; one control was a patient with a cancer, while the other was a patient without cancer, both conditions unrelated to As. Controls were matched with cases by age and sex. A standard survey containing questions about residence, employment, health history, was administered to study subjects. Data on As concentrations in water were obtained from records of the municipal water companies. A total of 151 lung cancer cases and 419 controls (167 with cancer and 242 without cancer were enrolled. Median level of lifetime As exposure was significantly higher among cases, with a clear dose-response relationship between mean As exposure levels, with an OR (95% CI of: 1, 1.7 (0.5-5.1, 3.9 (1.2-13.4, 5.5 (2.2-13.5, and 9.0 (3.6-22 for strata one to five respectively. This study provides new evidence that As in drinking water can cause internal cancers and gives an estimate of the form of this relationship.

    2000-01-01

    Cancer illness affects people in many ways, physical, financial, and existential. In this paper, we describe a proposed group intervention for individuals with advanced disease who want help finding a sense of meaning at this critical juncture in their lives. This intervention has a brief, semi-structured format, and is informed by the work of Viktor Frankl, empirical findings in the area of meaning and trauma, and the empirical findings of other group interventions for cancer patients. Individual sessions focus on different aspects of meaning, including responsibility to others, creativity, transcendence, and ascertaining one's values and priorities. Having goals on which to focus and feeling like part of a larger whole are critically important to the ability to find meaning and cope with terminal illness. Such goals may be generated by a number of sources, including connectedness with others, or a sense of the temporal continuity of one's own life despite the disruption posed by severe illness. Didactic discussions and experiential exercises help to facilitate exploration of these various elements in group members' lives. The finite structure of the intervention may also highlight these issues, as people who are faced with similar issues work together in a limited time frame in order to accomplish the goals they set out for themselves.

    2015-07-01

    Full Text Available Background: Acinetobacter baumannii complex (A. baumannii has been isolated worldwide. The rapid spread of multidrug-resistant A. baumannii complex (MDRAB in clinical settings has made choosing an appropriate antibiotic to treat these infections and executing contact precautions difficult for clinicians. Although controlling the transmission of MDRAB is a high priority for institutions, there is little information about MDRAB control. Therefore, this study evaluated infection control measures for A. baumannii infections, clusters and outbreaks in the literature. Methods: We performed a review of OVID Medline (from 1980 to 2015, and analyzed the literature. Results: We propose that both infection control programs and antibiotic control programs are essential for control of MDRAB. The first, effective control of MDRAB infections, requires compliance with a series of infection control methods including strict environmental cleaning, effective sterilization of reusable medical equipment, concentration on proper hand hygiene practices, and use of contact precautions, together with appropriate administrative guidance. The second strategy, effective antibiotic control programs to decrease A. baumannii, is also of paramount importance. Conclusion: We believe that both infection control programs and antibiotics stewardship programs are essential for control of MDRAB infections.

    Full Text Available Abstract Cancer control researchers seek to reduce the burden of cancer by studying interventions, their impact in defined populations, and the means by which they can be better used. The first step in cancer control is identifying where the cancer burden is elevated, which suggests locations where interventions are needed. Geographic information systems (GIS and other spatial analytic methods provide such a solution and thus can play a major role in cancer control. This report presents findings from a workshop held June 16–17, 2005, to bring together experts and stakeholders to address current issues in GIScience and cancer control. A broad range of areas of expertise and interest was represented, including epidemiology, geography, statistics, environmental health, social science, cancer control, cancer registry operations, and cancer advocacy. The goals of this workshop were to build consensus on important policy and research questions, identify roadblocks to future progress in this field, and provide recommendations to overcome these roadblocks.

    Literature suggests racial/ethnic minorities, particularly those who are less-acculturated, have stronger fatalistic attitudes toward cancer than do non-Latino Whites. Knowledge of cancer prevention is also lower among racial/ethnic minorities. Moreover, low knowledge about cancer risk factors is often associated with fatalistic beliefs. Our study examined fatalism and cancer knowledge by race/ethnicity and explored whether race/ethnicity moderate the association of fatalism with knowledge of cancer prevention and risk factors. We analyzed data from the Health Information National Trends Survey (2008), a national probability survey, to calculate population estimates of the associations among race/ethnicity, fatalistic beliefs, and knowledge about cancer from multivariable logistic regression. Racial/ethnic minorities had higher odds of holding fatalistic beliefs and lower odds of having knowledge of cancer risk factors than non-Hispanic Whites, and important differences by acculturation among Latinos were observed. Limited evidence of the moderating effect of race/ethnicity on the relationship between fatalistic beliefs and cancer risk factor knowledge was observed. Knowledge of cancer risk factors is low among all race/ethnicities, while fatalistic beliefs about cancer are higher among racial/ethnic minorities compared with non-Hispanic Whites. Implications for cancer education efforts are discussed.

    Full Text Available Prostate cancer is a major cause of morbidity and mortality in Iran, yet there are few studies examining risk factors specific to the Iranian context. We conducted a case-control study to explore risk factors for prostate cancer in Mazandaran, Iran from 2005 to 2008. The cases were 137 men with clinicopathologically confirmed prostate cancer. Controls were 137 neighborhood and age match men without prostate cancer by PSA and digit examination. Analysis comprised an exploratory stage to identify potential risk factors, defined as variables associated with case status at the P < 0.20 level in conditional logistic regression. A second stage included all potential risk factors in multiple conditional logistic regression analysis, retaining those associated with prostate cancer at the P < 0.05 level. Potential risk factors for prostate cancer in exploratory analysis included family history of prostate cancer, history of other cancer, prostatitis, alcohol consumption, pipe or hookah smoking, walking to work, duration of occupational physical activity, intensity of occupational physical activity, body mass index, and older age. Multivariate analysis found intensity of occupational physical activity, prostatitis, and older age as independent predictors of increased risk for prostate cancer in this Iranian population. Our study confirms several recognized risk factors for prostate cancer, contributes evidence to the discussions of other hypothesized risk factors, and points to potentially new factors. Findings, along with confirmatory studies, can help guide efforts for early detection, treatment, and prevention for this common malignancy that is set to increase in Iran in future decades.

    Dewi, C.; Trisilowati

    2015-03-01

    In this paper, an optimal control model of the growth of bladder cancer with BCG (Basil Calmate Guerin) immunotherapy and chemotherapy is discussed. The purpose of this optimal control is to determine the number of BCG vaccine and drug should be given during treatment such that the growth of bladder cancer cells can be suppressed. Optimal control is obtained by applying Pontryagin principle. Furthermore, the optimal control problem is solved numerically using Forward-Backward Sweep method. Numerical simulations show the effectiveness of the vaccine and drug in controlling the growth of cancer cells. Hence, it can reduce the number of cancer cells that is not infected with BCG as well as minimize the cost of the treatment.

    The Centers for Disease Prevention and Control's National Comprehensive Cancer Control (CCC) Program oversee CCC programs designed to develop and implement CCC plans via CCC coalitions, alliances, or consortia of program stakeholders. We reviewed 40 up-to-date plans for states and the District of Columbia in order to assess how capacity building and sustainability, two evidence-based practices necessary for organizational readiness, positive growth, and maintenance are addressed. We employed an electronic key word search, supplemented by full text reviews of each plan to complete a content analysis of the CCC plans. Capacity is explicitly addressed in just over half of the plans (53%), generally from a conceptual point of view, with few specifics as to how capacity will be developed or enhanced. Roles and responsibilities, timelines for action, and measurements for evaluation of capacity building are infrequently mentioned. Almost all (92%) of the 40 up-to-date plans address sustainability on at least a cursory level, through efforts aimed at funding or seeking funding, policy initiatives, and/or partnership development. However, few details as to how these strategies will be implemented are found in the plans. We present the Texas plan as a case study offering detailed insight into how one plan incorporated capacity building and sustainability into its development and implementation. Training, technical assistance, templates, and tools may help CCC coalition members address capacity and sustainability in future planning efforts and assure the inclusion of capacity building and sustainability approaches in CCC plans at the state, tribal, territorial, and jurisdiction levels.

  6. A case-control study of risk factors for epithelial ovarian cancer

    Full Text Available Ovarian cancer is second prevalent cancer among gynecologic malignancies and the most common type of ovarian cancer is epithelial form (85-90 percent. To detect the risk factors for the epithelial ovarian cancer, a case-control study was conducted in Valieasr hospital in 1988. In this study, 118 cases with epithelial ovarian cancer (according histological records and 240 controls without any gynecological cancer in gynecologic clinic had been interviewed. For data analysis, T-test, Chi2 test and logistic regression have been used at a =0.05 as level of significance. The mean age in cases was 50±13 and in controls was 49.9±12 years, without significant different. The mean number of pregnancies and parity in cases was less than controls, significantly (P<0.03. The mean months of breast feeding in cases was less than controls (54.9±71.2 versus 82.4±62.7 (P<0.001. The cases had a lower mean age of menarch than controls (P=0.03. 58 percent of cases and 21.3 percent of controls hadn't used any contraception methods (P=0.00001. The mean years of contraception was significantly less in cases versus controls (P<0.001. The odds ratio for epithelial ovarian cancer was 0.24 (95 percent CI: 0.13-0.48 in OCP users, 0.47 (95 percent CI: 0.005-0.43 in TL method, and was 0.41 (95 percent CI: 0.22-0.76 in other contraception methods, relative to women who hadn't used any contraception methods. This study reveals that epithelial ovarian cancer risk increases significantly with earlier menarch, decreasing number of pregnancy, deliveries duration of breast feeding and use of contraception methods. Use of contraception pill and tubal ligation method decreases risk of epithelial ovarian cancer.

    This study investigates the existence of economies of scale in the provision of breast and cervical cancer screening and diagnostic services by state National Breast and Cervical Cancer Early Detection Program (NBCCEDP) grantees. A translog cost function is estimated as a system with input factor share equations. The estimated cost function is then used to determine output levels for which average costs are decreasing (i.e., economies of scale exist). Data were collected from all state NBCCEDP programs and District of Columbia for program years 2006-2007, 2008-2009 and 2009-2010 (N = 147). Costs included all programmatic and in-kind contributions from federal and non-federal sources, allocated to breast and cervical cancer screening activities. Output was measured by women served, women screened and cancers detected, separately by breast and cervical services for each measure. Inputs included labor, rent and utilities, clinical services, and quasi-fixed factors (e.g., percent of women eligible for screening by the NBCCEDP). 144 out of 147 program-years demonstrated significant economies of scale for women served and women screened; 136 out of 145 program-years displayed significant economies of scale for cancers detected. The cost data were self-reported by the NBCCEDP State programs. Quasi-fixed inputs were allowed to affect costs but not economies of scale or the share equations. The main analysis accounted for clustering of observations within State programs, but it did not make full use of the panel data. The average cost of providing breast and cervical cancer screening services decreases as the number of women screened and served increases.

  8. Laboratory support of drug abuse control programs: an overview.

    Science.gov (United States)

    Decker, W J

    1977-01-01

    Labeling an individual a drug abuser has serious sociologic and legal implications that only laboratory testing can effectively allay. A proper specimen (both qualitatively and quantitatively) must be obtained for analysis. Positive identification of specimen with subject is of paramount importance. The problems of specimen substitution--other people's urine, tap water, apple juice--directly impinge here, as does the possibility of drug degradation by heat, light, and microbial attack and of drug adsorption by the container and urinary sediment. Confirmation of postives indicated by screening tests (thin layer chromatography and immunoassays) by gas chromatography and/or ultraviolet spectrophotometry is, in most situations, mandatory. An effective quality control program is an absolute requirement. Even under ideal circumstances, laboratory results can sometimes wrongly indicate the abuse of drugs; and conversely, drug abuse can take place without detection by the laboratory. As in any clinical situation, laboratory tests are only a part (albeit an important one) of the entire evaluation of the individual involved.

    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.

    Breast cancer is the most frequent malignant neoplasia worldwide. In emergent countries as Mexico, an increase has been shown in frequency and mortality, unfortunately, most cases in advanced loco-regional stages developed in young women. The success of breast screening in mortality reduction has been observed since 1995 in Western Europe and the United States, where as many as 40% mortality reduction has been achieved. Most countries guidelines recommends an annual or biannual mammography for all women >40 years of age. In 2005, FUCAM, a nonlucrative civil foundation in Mexico join with Mexico City government, initiated the first voluntary mammography screening program for women >40 years of age residing in Mexico City's Federal District. Mammographies were carried out with analogical mammographs in specially designed mobile units and were performed in the area of women's domiciles. This report includes data from the first 96,828 mammographies performed between March 2005 and December 2006. There were 1% of mammographies in Breast Imaging Reporting and Data System 0, 4, or 5 and 208 out of 949 women with abnormal mammographies (27.7%) had breast cancer, a rate of 2.1 per thousand, most of them in situ or stage I (29.4%) or stage II (42.2%) nevertheless 21% of those women with abnormal mammography did not present for further clinical and radiologic evaluation despite being personally notified at their home addresses. The breast cancer rate of Mexican women submitted to screening mammography is lower than in European or North American women. Family history of breast cancer, nulliparity, absence of breast feeding, and increasing age are factors that increase the risk of breast cancer. Most cancers were diagnosed in women's age below 60 years (68.5%) with a mean age of 53.55 corroborating previous data published. It is mandatory to sensitize and educate our population with regard to accepting to visit the Specialized Breast Centers.

    Intra-cellular signaling networks are crucial to the maintenance of cellular homeostasis and for cell behavior (growth, survival, apoptosis, movement). Mutations or alterations in the expression of elements of cellular signaling networks can lead to incorrect behavioral decisions that could result in tumor development and/or the promotion of cell migration and metastasis. Thus, mitigation of the cascading effects of such dysregulations is an important control objective. My group at Penn State is collaborating with wet-bench biologists to develop and validate predictive models of various biological systems. Over the years we found that discrete dynamic modeling is very useful in molding qualitative interaction information into a predictive model. We recently demonstrated the effectiveness of network-based targeted manipulations on mitigating the disease T cell large granular lymphocyte (T-LGL) leukemia. The root of this disease is the abnormal survival of T cells which, after successfully fighting an infection, should undergo programmed cell death. We synthesized the relevant network of within-T-cell interactions from the literature, integrated it with qualitative knowledge of the dysregulated (abnormal) states of several network components, and formulated a Boolean dynamic model. The model indicated that the system possesses a steady state corresponding to the normal cell death state and a T-LGL steady state corresponding to the abnormal survival state. For each node, we evaluated the restorative manipulation consisting of maintaining the node in the state that is the opposite of its T-LGL state, e.g. knocking it out if it is overexpressed in the T-LGL state. We found that such control of any of 15 nodes led to the disappearance of the T-LGL steady state, leaving cell death as the only potential outcome from any initial condition. In four additional cases the probability of reaching the T-LGL state decreased dramatically, thus these nodes are also possible control

    In diagnosis of lung cancer, rapid distinction between small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) tumors is very important. Serum markers, including lactate dehydrogenase (LDH), C-reactive protein (CRP), carcino-embryonic antigen (CEA), neurone specific enolase (NSE) and Cyfra21-1, are reported to reflect lung cancer characteristics. In this study classification of lung tumors was made based on biomarkers (measured in 120 NSCLC and 60 SCLC patients) by setting up optimal biomarker joint models with a powerful computerized tool - gene expression programming (GEP). GEP is a learning algorithm that combines the advantages of genetic programming (GP) and genetic algorithms (GA). It specifically focuses on relationships between variables in sets of data and then builds models to explain these relationships, and has been successfully used in formula finding and function mining. As a basis for defining a GEP environment for SCLC and NSCLC prediction, three explicit predictive models were constructed. CEA and NSE are frequently- used lung cancer markers in clinical trials, CRP, LDH and Cyfra21-1 have significant meaning in lung cancer, basis on CEA and NSE we set up three GEP models-GEP 1(CEA, NSE, Cyfra21-1), GEP2 (CEA, NSE, LDH), GEP3 (CEA, NSE, CRP). The best classification result of GEP gained when CEA, NSE and Cyfra21-1 were combined: 128 of 135 subjects in the training set and 40 of 45 subjects in the test set were classified correctly, the accuracy rate is 94.8% in training set; on collection of samples for testing, the accuracy rate is 88.9%. With GEP2, the accuracy was significantly decreased by 1.5% and 6.6% in training set and test set, in GEP3 was 0.82% and 4.45% respectively. Serum Cyfra21-1 is a useful and sensitive serum biomarker in discriminating between NSCLC and SCLC. GEP modeling is a promising and excellent tool in diagnosis of lung cancer.

The aim of this study was to investigate the role of spiritual therapy intervention in improving the spiritual well-being and quality of life (QOL of Iranian women with breast cancer. Methods. This randomized controlled clinical trial (RCT recruited 65 women with breast cancer, randomly assigned to a 6-week spirituality-based intervention (n=34 or control group (n=31. Before and after six-week spiritual therapy intervention, spiritual well-being and quality of life (QOL were assessed using Functional Assessment of Chronic Illness Therapy Spiritual Well-being scale (FACIT-Sp12 and cancer quality-of-life questionnaire (QLQ-C30, respectively. t-test, Paired t-test, pearson's correlation, and hierarchical regression analyses were used for analysis using Predictive Analytic software (PASW, version 18 for Windows. Results. After six spiritual therapy sessions, the mean spiritual well-being score from 29.76 (SD=6.63 to 37.24 (SD=3.52 in the intervention group (P<0.001. There was a significant difference between arms of study (F=22.91, P<0.001. A significant positive correlation was detected between meaning and peace with all subscales of functional subscales on European Organization for Research and Treatment of Cancer quality of Life (EORTC QLQ-C30 (P<0.05. Hierarchical regression analyses of participants indicated that the study arm, pain, and financial impact were significant predictors of spiritual well-being and overall QOL. Social functioning was another significant predictor of spiritual well-being. Conclusion. The results of this randomized controlled trial study suggest that participation in spiritual therapy program is associated with improvements in spiritual well-being and QOL. Targeted interventions to acknowledge and incorporate spiritual needs into conventional treatment should be considered in caring of Iranian patients with breast cancer.

    The aim of this study was to evaluate the cost-effectiveness of an organized breast cancer mammographic screening program implemented in Porto Alegre (Núcleo Mama Porto Alegre - NMPOA), Rio Grande do Sul State, Brazil. A Markov model was constructed to estimate the incremental cost-effectiveness ratio of NMPOA compared to current BC diagnosis and care in the Brazilian public health system, in a hypothetical cohort of women aged 40-69 years at risk of developing breast cancer. Model parameters were collected from NMPOA and the national literature. In the NMPOA strategy, effectiveness was modeled taking into account the actual observed screening adherence. Effectiveness was measured in quality-adjusted life years (QALYs). Incremental cost-effectiveness ratio in the base case was R$ 13,426 per QALY. This result was not sensitive to variation in the main model parameters in sensitivity analyses. Considering the threshold usually suggested as highly attractive in Brazil, breast cancer screening as performed in NMPOA is cost-effective in cities with high incidence of breast cancer.

    Problems with attention and symptom distress are common clinical features reported by women who receive adjuvant chemotherapy for breast cancer. Mindfulness practice significantly improves attention and mindfulness programs significantly reduce symptom distress in patients with cancer, and, more specifically, in women with breast cancer. Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention and decreased negative mood and fatigue in women with breast cancer. This paper delineates the design and development of the mindfulness-based music therapy (MBMT) program implemented in that pilot study and includes clients’ narrative journal responses. Conclusions and recommendations, including recommendation for further exploration of the function of music in mindfulness practice are provided. PMID:27517966

Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention and decreased negative mood and fatigue in women with breast cancer. This paper delineates the design and development of the mindfulness-based music therapy (MBMT) program implemented in that pilot study and includes clients' narrative journal responses. Conclusions and recommendations, including recommendation for further exploration of the function of music in mindfulness practice are provided.

    Cancer forms a robust system capable of maintaining stable functioning (cell sustenance and proliferation) despite perturbations. Cancer progresses as stages over time typically with increasing aggressiveness and worsening prognosis. Characterizing these stages and identifying the genes driving transitions between them is critical to understand cancer progression and to develop effective anti-cancer therapies. In this work, we propose a novel model for the `cancer system' as a Boolean state space in which a Boolean network, built from protein-interaction and gene-expression data from different stages of cancer, transits between Boolean satisfiability states by "editing" interactions and "flipping" genes. Edits reflect rewiring of the PPI network while flipping of genes reflect activation or silencing of genes between stages. We formulate a minimization problem min flip to identify these genes driving the transitions. The application of our model (called BoolSpace) on three case studies-pancreatic and breast tumours in human and post spinal-cord injury (SCI) in rats-reveals valuable insights into the phenomenon of cancer progression: (i) interactions involved in core cell-cycle and DNA-damage repair pathways are significantly rewired in tumours, indicating significant impact to key genome-stabilizing mechanisms; (ii) several of the genes flipped are serine/threonine kinases which act as biological switches, reflecting cellular switching mechanisms between stages; and (iii) different sets of genes are flipped during the initial and final stages indicating a pattern to tumour progression. Based on these results, we hypothesize that robustness of cancer partly stems from "passing of the baton" between genes at different stages-genes from different biological processes and/or cellular components are involved in different stages of tumour progression thereby allowing tumour cells to evade targeted therapy, and therefore an effective therapy should target a "cover set" of

    Non-communicable diseases, including cancer, are overtaking infectious disease as the leading health-care threat in middle-income and low-income countries. Latin American and Caribbean countries are struggling to respond to increasing morbidity and death from advanced disease. Health ministries and health-care systems in these countries face many challenges caring for patients with advanced cancer: inadequate funding; inequitable distribution of resources and services; inadequate numbers, training, and distribution of health-care personnel and equipment; lack of adequate care for many populations based on socioeconomic, geographic, ethnic, and other factors; and current systems geared toward the needs of wealthy, urban minorities at a cost to the entire population. This burgeoning cancer problem threatens to cause widespread suffering and economic peril to the countries of Latin America. Prompt and deliberate actions must be taken to avoid this scenario. Increasing efforts towards prevention of cancer and avoidance of advanced, stage IV disease will reduce suffering and mortality and will make overall cancer care more affordable. We hope the findings of our Commission and our recommendations will inspire Latin American stakeholders to redouble their efforts to address this increasing cancer burden and to prevent it from worsening and threatening their societies.

    Strontium has been widely used in industries like electronic and pharmacy. It has a carcinogenic potential, however, and no study has been conducted to evaluate its effects on cancer risk. The aim of this study was to explore the possible association between strontium and breast cancer risk in a case-control study including 240 incident invasive breast cancer patients and 246 age-matched controls. We measured the urinary concentrations of strontium by inductively coupled plasma mass spectrometry, and conducted face-to-face interviews to obtain information on potential breast cancer risk factors. Multivariable analysis was used to estimate the association. Creatinine-adjusted levels [median (25th, 75th) {mu}g/g] of strontium were 155.59 (99.05, 230.70) in the breast cancer patients and 119.62 (81.97, 163.76) in the controls. Women in the highest tertile of strontium showed 124% increased risk of breast cancer, when compared with those in the lowest tertile after adjustment for the potential risk factors [OR (95% CI): 2.24 (1.42-3.81)]. This association was particularly strong for HER2 positive breast cancer [OR (95% CI): 10.92 (3.53-33.77)], and only occurred among premenopausal women. These results suggest a potential role of strontium in the development of breast cancer and urge further studies on the environmental contamination and the physiological and pathological mechanisms of strontium.

    There is conflicting evidence surrounding the extent of changes in resting energy expenditure (REE) in cancer. This meta-analysis aimed to establish the mean difference in REE, as kilojoules per kilogram fat-free mass, among cancer patients when compared to healthy control subjects. The secondary aim was to determine differences among different cancer types. PubMed, Cochrane Library, Medline, Science Direct, Scopus, Web of Science, Wiley Online Library, and ProQuest Central were searched from the earliest records until March 2014. Studies were included if measured REE was reported as kilojoules or kilocalories per kilogram fat-free mass (FFM) in adult subjects with cancer. Twenty-seven studies were included in the meta-analysis. Fourteen studies included both cancer (n = 1453) and control (n = 1145) groups. The meta-analysis shows an average increase in REE of 9.66 (95% confidence interval: 3.34, 15.98) kJ/kgFFM/day in cancer patients when compared to control subjects. Heterogeneity was detected (P < 0.001) which suggest variations in REE among cancer types. Elevations are most noticeable in patients with cancers of metabolically demanding organs.

    Several epidemiologic studies have indicated an increased risk of lung cancer among welders. We used the SYNERGY project database to assess welding as a risk factor for developing lung cancer. The database includes data on 15,483 male lung cancer cases and 18,388 male controls from 16 studies in Europe, Canada, China, and New Zealand conducted between 1985 and 2010. Odds ratios and 95% confidence intervals between regular or occasional welding and lung cancer were estimated, with adjustment for smoking, age, study center, and employment in other occupations associated with lung cancer risk. Overall, 568 cases and 427 controls had ever worked as welders and had an odds ratio of developing lung cancer of 1.44 (95% confidence interval: 1.25, 1.67) with the odds ratio increasing for longer duration of welding. In never and light smokers, the odds ratio was 1.96 (95% confidence interval: 1.37, 2.79). The odds ratios were somewhat higher for squamous and small cell lung cancers than for adenocarcinoma. Another 1,994 cases and 1,930 controls had ever worked in occupations with occasional welding. Work in any of these occupations was associated with some elevation of risk, though not as much as observed in regular welders. Our findings lend further support to the hypothesis that welding is associated with an increased risk of lung cancer.

    2012-10-01

    Full Text Available Abstract Background Research on physical activity and nutrition interventions aimed at positively impacting symptom management, treatment-related recovery and quality of life has largely excluded head and neck (HN cancer populations. This translates into a lack of clinical programming available for these patient populations. HN cancer patients deal with severe weight loss, with more than 70% attributed to lean muscle wasting, leading to extended recovery times, decreased quality of life (QoL, and impaired physical functioning. To date, interventions to address body composition issues have focused solely on diet, despite findings that nutritional therapy alone is insufficient to mitigate changes. A combined physical activity and nutrition intervention, that also incorporates important educational components known to positively impact behaviour change, is warranted for this population. Our pilot work suggests that there is large patient demand and clinic support from the health care professionals for a comprehensive program. Methods/Design Therefore, the purpose of the present study is to examine the impact and timing of a 12-week PA and nutrition intervention (either during or following treatment for HN cancer patients on body composition, recovery, serum inflammatory markers and quality of life. In addition, we will examine the impact of a 12-week maintenance program, delivered immediately following the intervention, on adherence, patient-reported outcomes (i.e., management of both physical and psychosocial treatment-related symptoms and side-effects, as well as return to work. Discussion This research will facilitate advancements in patient wellness, survivorship, and autonomy, and carve the path for a physical-activity and wellness-education model that can be implemented in other cancer centers.

    Full Text Available Background and objective It has been proven that increase of the awareness level of lung cancer prevention and control could enhance participation of lung cancer screening of lung cancer high risk group. The aim of this study is to investigate the awareness level of lung cancer prevention and control and the effect of individual characteristics on lung cancer awareness, and to provide evidence for comprehensive lung cancer prevention in high risk areas of lung cancer. Methods Staffs of Tianjin Dagang Oil Field who participate low dose CT (LDCT lung cancer screening by cluster sampling or according to voluntary principle were surveyed, data of lung cancer awareness were collected by questionnaire. Results A total of 1,633 valid questionnaires were collected. The average age of respondents was 60.08±6.58. Most participants were males (82.2% while female only accounted for 17.8%. The proportions of awareness about lung cancer in China, risk factors, screening methods and the knowledge of health examination were 64.5%, 77.1%, 43.7%, 49.6% respectively. Result of multiple logistic regression analysis showed that education level, smoking (pack-year, age, prior tuberculosis were the influencing factors of lung cancer awareness with adjusted Ors for education and age level as of 0.567 (95%CI: 0.439-0.733 and 1.373 (95%CI: 1.084-1.739 respectively. 80.3% of the participants can accept health examination once a year, while the ability to pay the medical expenses was not high. The influencing factors of health examination willingness were gender, age, income, the knowledge of lung cancer. Conclusion Education level and smoking affect the awareness of lung cancer prevention and control, health education for lung cancer should be conducted especially in population with low education level. Comprehensive lung cancer control in high risk areas should combined lung cancer screening, tobacco control and health education.

    The relation between diazepam use and breast cancer was explored in two case-control studies. The first (1981-1987) was a hospital-based study in the United States of 3,078 cases of breast cancer, 1,259 controls with other malignancies, and 672 controls with nonmalignant conditions. The relative risk estimates for regular diazepam use (at least 4 days per week for at least 6 months) that antedated the diagnosis of breast cancer by at least 12 months were 1.0 (95% confidence interval (CI) 0.6-1.7) using the cancer controls and 0.8 (95% CI 0.4-1.8) using the noncancer controls. Risk factors for breast cancer were taken into account in the estimates. There was no association for regular use lasting at least 5 years or for regular use that took place exclusively in the recent or more distant past. The second study (1982-1986), conducted in Toronto, Ontario, Canada, was community-based, and included 607 cases of breast cancer and 1,214 neighbor controls selected from municipal voting and census records. After control of confounding, the relative risk estimate for regular diazepam use was 0.8 (95% CI 0.5-1.3). Again, there was no association for long-term, past, or recent regular use. The results of both studies suggest that regular diazepam use does not increase the risk of breast cancer. The findings are strengthened by the similarity of the results using three different control groups--women with cancer, women with nonmalignant conditions, and neighbors.

    Three screening programs for early cervical cancer currently in use in Japan were evaluated according to the following criteria: (1) economic effectiveness; (2) screening efficiency; and (3) access to medical care. The mobile program has the highest benefit-cost ratio (BCR, 1.20) and is hence most cost-effective; its detection rate, rescreening rate, and early cancer detection rate (proportion of Stage-O patients to all patients with cancer) are moderately high (0.09%, 2.07%, 55%, respectively). It is obviously suited to rural areas, especially where residents have a positive attitude toward local health services. The detection center program is less cost-effective than the mobile program (BCR, 0.83) but diagnostically the most effective with highest detection, rescreening, and early cancer detection rate (0.15%, 5.08%, 61%, respectively). It is suitable to large cities (population over 1 million) with efficient public transportation. The private physician program is economically and in terms of screening efficiency least effective of the three; its BCR being 0.40 and detection, rescreening, and early cancer detection rate being the lowest (0.08%, 0.29%, 33%, respectively). However, the private physician program is increasingly employed, presumably because of easy access to medical care, better rapport between the patient and physician, and, in addition, successful lobbying by private physicians.

  17. The Relationship between Food Intake and Bladder Cancer: A Case Control Study

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Background & aim: Bladder cancer is the second most common cancer of the urinary tract worldwide and the third most common cancer among Iranian males. Despite the relative high incidence of bladder cancer in Iran, no study has examined the relationship between dietary factors and bladder cancer. The aim of the present study was to investigate this relationship. Methods: The present case-control study was carried out on fifty-five patients with bladder cancer and including 110 cancer-free patients as controls. Dietary intake was evaluated using a food frequency questionnaire. To investigate the relationship between food items and bladder cancer, the subjects were classified according to the tertile of food items. The odds ratio was calculated for each tertile and the first tertile was considered as the reference group. Results: Our findings revealed that among food groups, animal fat (OR=19.76, fat (OR=12.92, junk foods (OR=8.1, organ meat (OR=5.47, processed meat (OR=5.34 and sweets (OR=3.62 were involved in the development of bladder cancer. In bladder carcinogenesis, an inverse association was recorded between consumption of low fat dairy products (OR=0.31, yoghurt (OR =0.14, fish (OR = 0.13, specific fruits (OR=0.13 and the development of bladder cancer. Conclusion: Animal products and sources of saturated fat are associated with an increased in risk of bladder cancer. The protective effect of olive oil, specific fruits, vegetables, low-fat dairy fermented was observed to reduce the risk of bladder cancer.

    The discovery and development of anticancer drugs with clinical potential are the responsibility of the Developmental Therapeutics Program (DTP), Division of Cancer Treatment, National Cancer Institute (NCI). Approximately 10,000 compounds/year are selectively acquired and screened against murine tumor models in order to discover new, active materials. The program required to accomplish this objective, as well as the subsequent tasks of formulation development and toxicology testing, is described. Since its inception in 1955, the preclinical new drug research program of the NCI has played a major role in the discovery and development of new agents which have been entered into clinical trial. The NCI has been responsible for the discovery of eight of the 16 commercially available drugs discovered since 1955. In addition, the NCI has played an important role in the clinical evaluation of all 16 of these New Drug Application (NDA)-approved drugs. During 1977-1982, the NCI filed Investigational New Drug Applications (INDA) for 33 cytotoxic agents. It was responsible for the discovery of the antitumor activity of 73% of these compounds. Most of the INDA compounds were acquired directly through NCI efforts. The DTP active acquisition program was responsible for obtaining 69% of these materials, with an additional 12% coming from the DTP intramural research program. Only 19% were received as voluntary submissions. The DTP active acquisition and screening effort is shown to have played even a larger role in identifying and obtaining those compounds which are currently in earlier stages of the NCI drug discovery and development process.

    2015-05-01

    Full Text Available There has been an increasing call to prospectively screen patients with breast cancer for the development of breast cancer-related lymphedema (BCRL following their breast cancer treatment. While the components of a prospective screening program have been published, some centers struggle with how to initiate, establish, and sustain a screening program of their own. The intent of this manuscript is to share our experience and struggles in establishing a prospective surveillance program within the infrastructure of our institution. It is our hope that by sharing our history other centers can learn from our mistakes and successes to better design their own prospective screening program to best serve their patient population.

    Objectives Investigate potential association between pioglitazone exposure and risk of prostate cancer. Research design and methods Nested, matched case–control study. UK primary care data (Clinical Practice Research Datalink (CPRD) GOLD) linked to inpatient (Hospital Episode Statistics (HES)) and cancer registry (National Cancer Information Network (NCIN)) data. English men aged ≥40 years diagnosed with type 2 diabetes mellitus, January 1, 2001 to January 5, 2015. Cases, with prostate cancer diagnosis, matched with up to 4 controls by age, cohort entry date and region. ORs for association of exposure to pioglitazone to incident prostate cancer, adjusted for potential confounders. Results From a cohort of 47 772 men with 243 923 person-years follow-up, 756 definite cases of prostate cancer were identified. Incidence was 309.9/100 000 person-years (95% CI 288.6 to 332.8). Pioglitazone use was not associated with prostate cancer risk; adjusted OR 0.759, 95% CI 0.502 to 1.148. Analyses showed no difference when possible cases, prostate cancer in CPRD GOLD only, included (adjusted OR 0.726, 95% CI 0.510 to 1.034). No association when adjusted for channeling bias (OR 0.778, 95% CI 0.511 to 1.184) or limited to an index date prior to July 1, 2011 (adjusted OR 0.508, 95% CI 0.294 to 0.879), despite prostate-specific antigen screening occurring more frequently among cases than controls (81.6% of 756 definite cases cf. 24.2% of 2942 controls (ppioglitazone use, increasing pioglitazone dose or increasing time since initiation. Conclusions In this real-world, nested matched case–control study, exposure to pioglitazone was not associated with increased risk of prostate cancer. PMID:28074141

    In 2007, an Italian cancer research group proposed a specific concerted action aimed at the "analytical and clinica validation of new biomarkers for early diagnosis: Network, resources, methodology, quality control, and data analysis." The proposal united 37 national operative units involved in different biomarker studies and it created a strong coordinative body with the necessary expertise in methodologies, statistical analysis, quality control, and biological resources to perform ad hoc validation studies for new biomarkers of early cancer diagnosis. The action, financed by the Italian Ministry of Health within the Integrated Oncology Program (PIO) coordinated by NCI-Istituto Tumori Bari, started in 2007 and activated 7 projects, each of which focused on disease-specific biomarker studies. Overall, the 37 participating units proposed studies on 50 biomarkers, including analytical and clinical validation procedures. Clusters of units were specifically involved in research of early-detection biomarkers for cancers of the lung, digestive tract, prostate/bladder, and nervous system, as well as female cancers. Furthermore, a cluster involved in biomarkers for bioimaging and infection-related cancers was created. The first investigators' meeting, "Analytical and clinical validation of new biomarkers for early diagnosis," was held on 9 September 2008 in Bari. During this meeting, methodological aspects, scientific programs and preliminary results were presented and discussed.

    Flight weight digital computers are being used today to carry out many of the propulsion system control functions previously delegated exclusively to hydromechanical controllers. An operational digital computer facility for propulsion control mode studies has been used successfully in several experimental programs. This paper describes the system and some of the results concerned with engine control, inlet control, and inlet engine integrated control. Analytical designs for the digital propulsion control modes include both classical and modern/optimal techniques.

    A New Zealand Cancer Registry based case-control study involved 617 male patients with prostate cancer registered during 1979 and aged 20 years or more at the time of registration. Controls were also males chosen from the Cancer Registry with two controls per case, matched on age and year of registration. There was an elevated risk in the upper social class groupings. The data did not support the findings, from other countries, of elevated risks in agricultural workers (odds ratio = 1.08, 90% confidence limits 0.86-1.36). The only occupational groups showing elevated risks were sales and service workers (odds ratio = 1.29, 90% confidence limits 0.99-1.69) and teachers (odds ratio = 2.44, 90% confidence limits 1.05-5.70). The New Zealand data do not in general suggest that occupational factors--or lifestyle factors associated with occupation--are of major direct importance in the aetiology of prostate cancer.

    French Polynesia has one of the world's highest thyroid cancer incidence rates. A case-control study among native residents of French Polynesia included 229 cases of differentiated thyroid cancer diagnosed between 1979 and 2004, and 371 population controls. Dietary patterns and goitrogenic food consumption (cabbage, cassava) were analyzed. We used a factor analysis to identify dietary patterns and a conditional logistic regression analysis to investigate the association between dietary patterns or food items and thyroid cancer risk. Two distinct dietary patterns were identified: traditional Polynesian and Western. A nonsignificant inverse association was observed between the traditional Polynesian dietary pattern and thyroid cancer risk. The Western pattern was not associated with thyroid cancer risk. Cassava consumption was significantly associated with a decreased risk of thyroid cancer. In conclusion, a traditional Polynesian dietary pattern led to a weak reduced risk of thyroid cancer in French Polynesia. The protective effect of cassava on this cancer does not seem to be substantially different from that of cabbage, which was the main goitrogenic food studied to date.

    Diabetes has been associated to the risk of a few cancer sites, though quantification of this association in various populations remains open to discussion. We analyzed the relation between diabetes and the risk of various cancers in an integrated series of case-control studies conducted in Italy and Switzerland between 1991 and 2009. The studies included 1,468 oral and pharyngeal, 505 esophageal, 230 gastric, 2,390 colorectal, 185 liver, 326 pancreatic, 852 laryngeal, 3,034 breast, 607 endometrial, 1,031 ovarian, 1,294 prostate, and 767 renal cell cancer cases and 12,060 hospital controls. The multivariate odds ratios (OR) for subjects with diabetes as compared to those without-adjusted for major identified confounding factors for the cancers considered through logistic regression models-were significantly elevated for cancers of the oral cavity/pharynx (OR = 1.58), esophagus (OR = 2.52), colorectum (OR = 1.23), liver (OR = 3.52), pancreas (OR = 3.32), postmenopausal breast (OR = 1.76), and endometrium (OR = 1.70). For cancers of the oral cavity, esophagus, colorectum, liver, and postmenopausal breast, the excess risk persisted over 10 yr since diagnosis of diabetes. Our data confirm and further quantify the association of diabetes with colorectal, liver, pancreatic, postmenopausal breast, and endometrial cancer and suggest forthe first time that diabetes may also increase the risk of oral/pharyngeal and esophageal cancer.

    Full Text Available Background : In India, prostate cancer is one of the five leading sites of cancers among males in all the registries. Very little is known about risk factors for prostate cancer among the Indian population. Objectives : The present study aims to study the association of lifestyle factors like chewing (betel leaf with or without tobacco, pan masala, gutka, smoking (bidi, cigarette, comorbid conditions, diet, body mass index (BMI, family history, vasectomy with prostate cancer. Materials and Methods : This an unmatched hospital-based case-control study, comprised of 123 histologically proven prostate ′cancer cases′ and 167 ′normal controls. Univariate and regression analysis were applied for obtaining the odds ratio for risk factors. Results : The study revealed that there was no significant excess risk for chewers, alcohol drinkers, tea and coffee drinkers, family history of cancer, diabetes, vasectomy and dietary factors. However, patients with BMI >25 (OR = 2.1, those with hypertension history (OR = 2.5 and age >55 years (OR = 19.3 had enhanced risk for prostate cancer. Conclusions : In the present study age, BMI and hypertension emerged as risk factors for prostate cancer. The findings of this study could be useful to conduct larger studies in a more detailed manner which in turn can be useful for public interest domain.

    Full Text Available Abstract Background Tobacco smoke exposure may be associated with increased breast cancer risk, although the evidence supporting the association is inconclusive. We conducted a case-control study in Delaware, incorporating detailed exposure assessment for active and secondhand smoke at home and in the workplace. Methods Primary invasive breast cancer cases diagnosed among female Delaware residents, ages 40–79, in 2000–2002 were identified through the Delaware cancer registry (n = 287. Delaware drivers license and Health Care Finance Administration records were used to select age frequency-matched controls for women Results A statistically significant increased risk of breast cancer was observed for ever having smoked cigarettes (odds ratio = 1.43, 95% confidence interval = 1.03–1.99. However, there was no evidence of a dose-response relationship between breast cancer risk and total years smoked, cigarettes per day, or pack-years. Neither residential nor workplace secondhand smoke exposure was associated with breast cancer. Recalculations of active smoking risks using a purely unexposed reference group of women who were not exposed to active or secondhand smoking did not indicate increased risks of breast cancer. Conclusion These findings do not support an association between smoking and breast cancer.

    The Cancer Prevention and Control Research Network (CPCRN) is a thematic network dedicated to accelerating the adoption of evidence-based cancer prevention and control practices in communities by advancing dissemination and implementation science. Funded by the Centers for Disease Control and Prevention and National Cancer Institute, CPCRN has operated at two levels: Each participating network center conducts research projects with primarily local partners as well as multicenter collaborative research projects with state and national partners. Through multicenter collaboration, thematic networks leverage the expertise, resources, and partnerships of participating centers to conduct research projects collectively that might not be feasible individually. Although multicenter collaboration is often advocated, it is challenging to promote and assess. Using bibliometric network analysis and other graphical methods, this paper describes CPCRN's multicenter publication progression from 2004 to 2014. Searching PubMed, Scopus, and Web of Science in 2014 identified 249 peer-reviewed CPCRN publications involving two or more centers out of 6,534 total. The research and public health impact of these multicenter collaborative projects initiated by CPCRN during that 10-year period were then examined. CPCRN established numerous workgroups around topics such as: 2-1-1, training and technical assistance, colorectal cancer control, federally qualified health centers, cancer survivorship, and human papillomavirus. This paper discusses the challenges that arise in promoting multicenter collaboration and the strategies that CPCRN uses to address those challenges. The lessons learned should broadly interest those seeking to promote multisite collaboration to address public health problems, such as cancer prevention and control.

    Breast cancer is the main cause of cancer-related death among women, with a 0.5% increase in incidence per year. Natural killer cells (NK) are part of the innate immune system recognizing class I HLA molecules on target cells through their membrane receptors, called killer cell immunoglobulin-like receptors (KIR). The aim of our study was to evaluate the association between the KIR genes and HLA alleles in patients with breast cancer and healthy controls. Two hundred thirty patients with breast cancer and 272 healthy controls were typed for HLA class I and KIR genes by PCR-SSO. When both groups were compared, the presence of inhibitory KIR2DL2 receptors was significantly higher in breast cancer patients than in healthy controls. No significant differences were found for HLA-C2 and HLA-Bw4. However, a higher frequency of HLA-C1 in breast cancer patients was observed. These findings suggest a potential role for the KIR gene system in breast cancer. Further studies to confirm this observation are warranted.

    2002-01-01

    A case-control study was undertaken to study lung cancer in relation to dietary habits, occupational exposure, and living in urban or country areas. Suspect lung cancer cases in West Sweden and population controls were interviewed using a food frequency questionnaire. The study comprised 177 female and 359 male cases and 916 controls. The cases mainly comprised former and current smokers (82% female, 95% male). For the analysis, cases were divided into the histological diagnoses adenocarcinoma and squamous cell, small cell, and adenosquamous cell carcinomas, as well as into smoking categories. A high frequency of consumption of vegetables was significantly related to a lower risk for adenocarcinoma and squamous cell and adenosquamous cell carcinoma among men and adenocarcinoma among women. A low odds ratio in the highest quartile of vegetable consumption in men was seen in all smoking categories. There were no significant protective effects from fruit in the different lung cancer subgroups, although a significant trend was found for heavy-smoking females. A high consumption of milk was related to an increased risk for lung cancer, especially adenosquamous cell carcinoma. The results suggest that the protective effect or risk due to dietary factors may affect different forms of lung cancer. The results from this as well as previous studies suggest a complex interaction between diet and lung cancer risk, involving the types of lung cancer as well as consumption patterns in the population.

    Full Text Available Increasing access to clinically beneficial targeted cancer medicines is a challenge in every country due to their high cost. We describe the interplay of innovative policies and programs involving multiple stakeholders to facilitate access to these medicines in Thailand, as well as the utilization of selected targeted therapies over time.We selected two medicines on the 2013 Thai national list of essential medicines (NLEM [letrozole and imatinib] and three unlisted medicines for the same indications [trastuzumab, nilotinib and dasatinib]. We created timelines of access policies and programs for these products based on scientific and grey literature. Using IMS Health sales data, we described the trajectories of sales volumes of the study medicines between January 2001 and December 2012. We compared estimated average numbers of patients treated before and after the implementation of policies and programs for each product.Different stakeholders implemented multiple interventions to increase access to the study medicines for different patient populations. During 2007-2009, the Thai Government created a special NLEM category with different coverage requirements for payers and issued compulsory licenses; payers negotiated prices with manufacturers and engaged in pooled procurement; pharmaceutical companies expanded patient assistance programs and lowered prices in different ways. Compared to before the interventions, estimated numbers of patients treated with each medicine increased significantly afterwards: for letrozole from 645 (95% CI 366-923 to 3683 (95% CI 2,748-4,618; for imatinib from 103 (95% CI 72-174 to 350 (95% CI 307-398; and for trastuzumab from 68 (95% CI 45-118 to 412 (95% CI 344-563.Government, payers, and manufacturers implemented multi-pronged approaches to facilitate access to targeted cancer therapies for the Thai population, which differed by medicine. Routine monitoring is needed to assess clinical and economic impacts of these

    2016-01-01

    Cancer survivors (CA) tend to demonstrate metabolic, cardiac, and ventilatory alterations due to previous chemotherapy and radiation that may impair adaptability following aerobic exercise training. Exercise training adaptations of CA finished with primary treatment compared to non-cancer participants (NC) have not yet been extensively elucidated. Thus, the present study compared physiologic responses of CA versus NC following a low-to-moderate intensity, 8-wk aerobic training program. Thirty-seven previously sedentary participants (CA: n = 14, 12 females; NC: n = 23, 19 females) with no heart or metabolic disease did not differ in age, height, weight, and body mass index (51 ± 2 y, 1.66 ± 0.02 m, 83.8 ± 3.2 kg, and 30.5 ± 1 kg·m-2). Each participant underwent baseline, 3-, 6-, and 8-wk VO2peak treadmill testing using the USAFSAM protocol and walked on a treadmill three times per week at 80-90% of ventilatory threshold (VT) for approximately 40-min·session-1. Variables obtained on the VO2peak tests included: HR at stage 2 (HR@stage2), rating of perceived exertion at stage 2 (RPE@stage2), lactate threshold (LT), ventilatory threshold (VT), salivary cortisol at 30-min post VO2peak test (SC@30-minPost),VO2peak level, time of fatigue (TOF), and maximal heart rate (HRmax). NC had significantly (p exercise capacity during 8 weeks of aerobic training and did not show altered adaptability compared to NC. We suggest prescribing aerobic exercise training at low/moderate intensity and duration initially, with progressive increases in duration and intensity after approximately 8-weeks. If available and supported, we advise clinicians to utilize submaximal threshold concepts obtained from cardiopulmonary exercise testing to prescribe more precise aerobic exercise training parameters. Key points Cancer survivors will most likely begin an exercise program after cancer therapy with a diminished functional capacity whereby baseline cardiopulmonary testing is recommended. By

    Skin cancer is the most common cancer in the USA and is increasing in children and young adults. Adolescents are an important target population for sun-safety interventions with ultraviolet radiation as the strongest risk factor for developing skin cancer. Schools are an ideal setting to intervene with adolescents. A novel Arizona skin cancer prevention in-class education-activity program, Project 'Students are Sun Safe' (SASS), was designed to be delivered by university students for middle school and high school students. Participant students completed the pre- and post-program tests and a satisfaction questionnaire; teachers completed reviews. The evaluation examined the program's influence on participants' sun-safety knowledge, perceptions, and behaviors; satisfaction with the program; and intent to change. After exposure to Project SASS, participants were more likely to perceive a high risk of skin cancer, report negative attitudes toward tanned skin, and answer knowledge-based questions correctly. There were minimal differences in self-reported sun-safety behaviors, though participants did report intent to change. Both participants and teachers were satisfied with the program. Project SASS appears to be an effective sun-safety program for middle school and high school students for knowledge and perceptions, and the results confirm that appropriately tailoring program components to the target population has strong potential to impact adolescent perceived susceptibility, knowledge, and behavioral intent. The strengths and weaknesses of Project SASS have many implications for public health practice, and Project SASS may hold promise to be a model for skin cancer prevention in adolescents.

  3. Endomembrane control of cell polarity: Relevance to cancer.

    Baschieri, Francesco; Farhan, Hesso

    2015-01-01

    The role of polarity in cancer is an emerging research area and loss of polarity is widely considered an important event in cancer. Among the polarity regulating molecules, the small GTPase Cdc42 was extensively studied. Most attention was given to Cdc42 signaling at the plasma membrane, but whether and how Cdc42 is regulated at endomembranes remained poorly understood. Moreover, whether the endomembrane pool of Cdc42 is of any relevance to cell polarity was unknown. In our recent work, we identified a complex between the Golgi matrix protein GM130 and RasGRF and showed that it is responsible for regulating the Golgi pool of Cdc42, but had no effect on the plasma membrane pool of Cdc42. Depletion of GM130 disrupted apico-basal polarity as well as front-rear polarity, indicating that the spatial pool of Cdc42 is functionally relevant. The biomedical relevance of this finding was supported by the observation than GM130 is progressively lost in colorectal cancer. These findings support a role of the endomembrane pool of Cdc42 in cell polarity and point to a potential role of alterations of this pool in cancer.

    Purpose: The National Cancer Institute (NCI) Community Cancer Centers Program (NCCCP) began in 2007; it is a network of community-based hospitals funded by the NCI. Quality of care is an NCCCP priority, with participation in the American Society of Clinical Oncology Quality Oncology Practice Initiative (QOPI) playing a fundamental role in quality assessment and quality improvement (QI) projects. Using QOPI methodology, performance on quality measures was analyzed two times per year over a 3-year period to enhance our implementation of quality standards at NCCCP hospitals. Methods: A data-sharing agreement allowed individual-practice QOPI data to be electronically sent to the NCI. Aggregated data with the other NCCCP QOPI participants were presented to the network via Webinars. The NCCCP Quality of Care Subcommittee selected areas in which to focus subsequent QI efforts, and high-performing practices shared voluntarily their QI best practices with the network. Results: QOPI results were compiled semiannually between fall 2010 and fall 2013. The network concentrated on measures with a quality score of ≤ 0.75 and planned voluntary group-wide QI interventions. We identified 13 measures in which the NCCCP fell at or below the designated quality score in fall 2010. After implementing a variety of QI initiatives, the network registered improvements in all parameters except one (use of treatment summaries). Conclusion: Using the NCCCP as a paradigm, QOPI metrics provide a useful platform for group-wide measurement of quality performance. In addition, these measurements can be used to assess the effectiveness of QI initiatives. PMID:25538082

    Full Text Available Abstract Background In the US, Hispanic women have a higher incidence of, and mortality from, cervical cancer than non-Hispanic white women. The reason for this disparity may be attributable to both low rates of screening and poor adherence to recommended diagnostic follow-up after an abnormal Pap test. The 'Cervical Cancer Screening and Adherence to Follow-up Among Hispanic Women' study is a collaboration between a research institution and community partners made up of members from community based organizations, the Yakima Valley Farm Workers Clinic and the Breast, Cervical, and Colon Health Program of the Yakima District . The study will assess the efficacy of two culturally-appropriate, tailored educational programs designed to increase cervical cancer screening among Hispanic women, based in the Yakima Valley, Washington, US. Methods/design A parallel randomized-controlled trial of 600 Hispanic women aged 21–64, who are non-compliant with Papanicolau (Pap test screening guidelines. Participants will be randomized using block randomization to (1 a control arm (usual care; (2 a low-intensity information program, consisting of a Spanish-language video that educates women on the importance of cervical cancer screening; or (3 a high-intensity program consisting of the video plus a ‘promotora’ or lay-community health educator-led, home based intervention to encourage cervical cancer screening. Participants who attend cervical cancer screening, and receive a diagnosis of an abnormal Pap test will be assigned to a patient navigator who will provide support and information to promote adherence to follow-up tests, and any necessary surgery or treatment. Primary endpoint: Participants will be tracked via medical record review at community-based clinics, to identify women who have had a Pap test within 7 months of baseline assessment. Medical record reviewers will be blinded to randomization arm. Secondary endpoint: An evaluation of the patient

    Science.gov (United States)

    Janecka, Ivo P

    2007-06-05

    Cancer is a significant medical and societal problem. This reality arises from the fact that an exponential and an unrestricted cellular growth destabilizes human body as a system. From this perspective, cancer is a manifestation of a system-in-failing.A model of normal and abnormal cell cycle oscillations has been developed incorporating systems science, complexity, and chaos theories. Using this model, cancer expresses a failing subsystem and is characterized by a positive exponential growth taking place in the outer edge of chaos. The overall survival of human body as a system is threatened. This model suggests, however, that cancer's exponential cellular growth and disorganized complexity could be controlled through the process of induction of differentiation of cancer stem cells into cells of low and basic functionality. This concept would imply reorientation of current treatment principles from cellular killing (cyto-toxic therapies) to cellular retraining (cyto-education).

    Full Text Available Background. About 65% of cancer deaths globally occur in low to middle income countries (LMICs where prioritization and allocation of resources to cancer care are often quite poor. In the absence of governmental focus on this problem, public-private partnerships may be an avenue to provide effective cancer control. Methods. This manuscript highlights the establishment of a nongovernmental organization (NGO to stimulate the development of partnerships between oncology professionals, private enterprise, and academic institutions, both locally and internationally. Examples of capacity building, grant support, establishment of collaborative networks, and the development of a facility to provide clinical care are highlighted. Results. Collaborations were established between oncology professionals at academic institutions in the US and Nigeria. Cancer control workshops were conducted in Nigeria with grant support from the Union for International Cancer Control (UICC. A monthly tumor board conference was established at LASUTH in Lagos, and further capacity building is underway with grant support from the United States NCI. An outpatient, privately funded oncology clinic in Lagos has been launched. Conclusion. In LMICs, effective partnership between public and private institutions can lead to tangible strides in cancer control. The use of creative healthcare financing models can also support positive change.

    Moore, J H

    1995-06-01

    A genetic algorithm for instrumentation control and optimization was developed using the LabVIEW graphical programming environment. The usefulness of this methodology for the optimization of a closed loop control instrument is demonstrated with minimal complexity and the programming is presented in detail to facilitate its adaptation to other LabVIEW applications. Closed loop control instruments have variety of applications in the biomedical sciences including the regulation of physiological processes such as blood pressure. The program presented here should provide a useful starting point for those wishing to incorporate genetic algorithm approaches to LabVIEW mediated optimization of closed loop control instruments.

    Full Text Available To reduce the number of unnecessary biopsies in patients with benign prostatic disease, however, without missing significant PCa the present study re-evaluates the age-dependent PSA cut-offs in the Tyrol Prostate Cancer (PCa early detection program.The study population included 2225 patients who underwent prostate biopsy due to elevated PSA levels at our department. We divided our patient collective into four age groups: ≤49 years (n = 178, 50-59 years (n = 597, 60-69 years (n = 962 and ≥70 years (n = 488. We simulated different scenarios for PSA cut-off values between 1.25 and 6 ng/mL and fPSA% between 15 and 21% for all four age groups and calculated sensitivity, specificity, confidence intervals and predictive values.PCa was detected in 1218 men (54.7%. We found that in combination with free PSA ≤21% the following PSA cut-offs had the best cancer specificity: 1.75 ng/ml for men ≤49 years and 50-59 years, 2.25 ng/ml for men aged 60-69 years and 3.25 ng/ml for men ≥70 years. Using these adjusted PSA cut-off values all significant tumors are recognized in all age groups, yet the number of biopsies is reduced. Overall, one biopsy is avoided in 13 to 14 men (number needed to screen = 13.3, reduction of biopsies = 7.5% when decision regarding biopsy is done according to the "new" cut-off values instead of the "old" ones. For the different age groups the number needed to screen to avoid one biopsy varied between 9.2 (≤49 years and 17.4 (50-59 years.With "new", fine-tuned PSA cut-offs we detect all relevant PCa with a significant reduction of biopsies compared to the "old" cut-off values. Optimization of age-specific PSA cut-offs is one step towards a smarter strategy in the Tyrol PCa Early Detection Program.

    Full Text Available Background: Researchers have reported association of plasma/serum lipids and lipoproteins with different cancers. Increase levels of circulating lipids and lipoproteins have been associated with breast cancer risk. Aim: The aim of this study is to compare serum lipid profiles: total-cholesterol (T-CHOL, triglyceride (TG, high density lipoprotein-cholesterol (HDL-C, low density lipoprotein-cholesterol (LDL-C and very low density lipoprotein-cholesterol (VLDL-C between breast cancer patients and normal participants. Materials and Methods: A total of 403 women in this study were divided into two groups in the period during May 2006-April 2007. Blood samples were collected from 249 patients with early stage breast cancer and 154 normal controls for serum lipid profiles (T-CHOL, TG, HDL-C, LDL-C and VLDL-C analysis using Hitachi 717 Autoanalyzer (Roche Diagnostic GmbH, Germany. TG, LDL-C and VLDL-C levels in breast cancer group were significantly increased as compared with normal controls group (P < 0.001, whereas HDL-C and T-CHOL levels were not. Results: The results of this study suggest that increased serum lipid profiles may associate with breast cancer risk in Thai women. Further studies to group important factors including, cancer stages, types of cancer, parity, and menopausal status that may affect to lipid profiles in breast cancer patients along with an investigation of new lipid profiles to clarify most lipid factors that may involve in breast cancer development are needed.

    This study focuses on the association between the ABO blood group system and the risk of gastric cancer or Helicobacter pylori infection. The data for the ABO blood group was collected from 1045 cases of gastric cancer, whereby the patient underwent a gastrectomy in Ruijin Hospital, Shanghai. The information on the ABO blood group from 53,026 healthy blood donors was enrolled as control. We searched the Pubmed database on the relationship between ABO blood groups and gastric cancer risk for meta-analysis. In our case-control study, the risk of gastric cancer in blood group A was significantly higher than that in non-A groups (O, B and AB) (odd ratio, OR1.34; 95% confidential interval, CI 1.25-1.44). Compared with non-O groups (A, B and AB), individuals with blood group O demonstrated a reduced risk of gastric cancer (OR = 0.80; 95% CI 0.72-0.88). The proportion of H. pylori infection in blood group A individuals was significantly higher than that in non-A blood groups (OR = 1.42; 95% CI 1.05-1.93). We further combined our data with the published data of others, and crossreferenced the risk of gastric cancer with the blood type, finding consistent evidence that gastric cancer risk in the blood A group was higher than that in the non-A groups (OR = 1.11; 95% CI 1.07-1.15), and that blood type O individuals were consistently shown gastric cancer risk reduction (OR = 0.91; 95% CI 0.89-0.94). Our study concluded that there was a slightly increased risk of gastric cancer in blood group A individuals, and people with blood type A are more prone to be infected by H. pylori than other ABO blood type individuals, whereas, a slightly decreased risk of gastric cancer was identified in blood type O individuals.

    Full Text Available Abstract Background Digitoxin induces apoptosis in different human malignant cell lines in vitro. In this paper we investigated if patients taking digitoxin for cardiac disease have a different cancer incidence compared to the general population. Methods Computer stored data on digitoxin concentrations in plasma from 9271 patients with cardiac disease were used to define a user population. Age and sex matched controls from the Norwegian Cancer Registry were used to calculate the number of expected cancer cases. Results The population on digitoxin showed a higher incidence of cancer compared to the control population. However, an additional analysis showed that the population on digitoxin had a general increased risk of cancer already, before the start on digitoxin. Leukemia/lymphoma were the cancer types which stood out with the highest risk in the digitoxin population before starting on digitoxin. This indicates that yet unknown risk factors exist for cardiovascular disease and lymphoproliferative cancer. An internal dose-response analysis revealed a relationship between high plasma concentration of digitoxin and a lower risk for leukemia/lymphoma and for cancer of the kidney/urinary tract. Conclusion Morbidity and mortality are high in the population on digitoxin, due to high age and cardiac disease.These factors disturb efforts to isolate an eventual anticancer effect of digitoxin in this setting. Still, the results may indicate an anticancer effect of digitoxin for leukemia/lymphoma and kidney/urinary tract cancers. Prospective clinical cancer trials have to be done to find out if digitoxin and other cardiac glycosides are useful as anticancer agents.

    The purpose of the present paper was to evaluate the effects of an 8-week multimodal program focused on core stability exercises and recovery massage with DVD support for a 6-month period in physical and psychological outcomes in breast cancer survivors. A randomized controlled clinical trial was performed. Seventy-eight (n = 78) breast cancer survivors were assigned to experimental (core stability exercises plus massage-myofascial release) and control (usual health care) groups. The intervention period was 8 weeks. Mood state, fatigue, trunk curl endurance, and leg strength were determined at baseline, after the last treatment session, and at 6 months of followup. Immediately after treatment and at 6 months, fatigue, mood state, trunk curl endurance, and leg strength exhibited greater improvement within the experimental group compared to placebo group. This paper showed that a multimodal program focused on core stability exercises and massage reduced fatigue, tension, depression, and improved vigor and muscle strength after intervention and 6 months after discharge.

    Full Text Available In Albania, breast cancer is an important cause of death among women, with increasing incidence from 65 cases in 1970, to 400 cases in 2007. This is the first study concerning breast cancer risk factors in Albania. We used a population-based case-control study of 948 women with breast cancer compared with 1019 controls recruited from other hospitals through random selection. Early age at menarche was found to be a significantly strong risk factor during the pre- and postmenopausal groups with OR 10.04 and 12.1, respectively. In addition, nulliparity is associated with higher risk while abortion did not indicate any influence in the multivariate model. The findings from this study have shown that reproductive and menstrual variables are significant predictors of breast cancer risk in Albanian women, as seen in studies of other western countries.

    The relationship between cigarette smoking, vodka drinking and consumption of 44 food items typical of the Polish diet were analysed in a case-control study in Cracow, Poland, among 127 cases of breast cancer and 250 controls randomly selected from the general population. Cigarette smoking was not significantly influencing the breast cancer risk. Compared with never-drinkers, the habit of vodka drinking 20 years earlier significantly increased breast cancer risk in women below 50 years of age (multivariate OR was 4.4 with 95% CI 1.6-12.4). Frequent consumption of boiled vegetables 20 years earlier (greater than 3 times per week) was associated with a decreased risk of breast cancer in women aged 50 years and more (multivariate OR was 0.4 with 95% CI 0.2-0.8).

    Full Text Available In this paper a single input fuzzy controller is applied on autonomous drug-encapsulated nanoparticles (ADENPs to restrict the cancer growth. The proposed ADENPs, swarmly release the drug in local cancerous tissue and effectively decreases the destruction of normal tissue. The amount of released drug is defined considering to feed backed values of tumor growth rate and the used drug. Some significant characteristics of Nano particles compared to Nano-robots is their ability to recognize the cancerous tissue from the normal one and their simple structure. Nano particles became an attractive topic in Nano science and many efforts have been done to manufacture these particles. Simulation results show that the proposed controlling method not only decreases the cancerous tissue effectively but also reduces the side effects of drug impressively.

    An investigation based on a large population-based case-control study in British Columbia, Canada, was conducted to identify high-risk occupations for lung cancer by histological subtypes. Subjects were 14,755 male incident cancer cases for whom lifetime occupational histories and information on smoking and relevant covariates were collected. Occupational associations for 2998 lung cancer cases, including histological subtypes, were assessed by logistic regression using other cancer cases, excluding smoking-related cancers, as controls. An excess risk of lung cancer was found among workers in metal processing, bakers, and ship deck crew for all histological subtypes, and construction workers, chefs and cooks, and medical workers for specific histological subtypes. Occupational associations that are unique to histological subtypes of lung cancer were identified. Owing to a scarcity of literature in this area, future research needs to focus on confirming these histological associations, and identifying the risk from key exposures found within these occupations (e.g., medical radiation, electromagnetic fields, and cooking fumes).

    Persistent infection of the gastric mucosa by Helicobacter pylori, can initiate an inflammatory cascade that progresses into atrophic gastritis, a condition associated with reduced capacity for secretion of gastric acid and an increased risk in developing gastric cancer. The role of H. pylori as an initiator of inflammation is evident but the mechanism for development into gastric cancer has not yet been proven. A reduced capacity for gastric acid secretion allows survival and proliferation of other microbes that normally are killed by the acidic environment. It has been postulated that some of these species may be involved in the development of gastric cancer, however their identities are poorly defined. In this study, the gastric microbiota from ten patients with gastric cancer was characterized and compared with five dyspeptic controls using the molecular profiling approach, terminal-restriction fragment length polymorphism (T-RFLP), in combination with 16S rRNA gene cloning and sequencing. T-RFLP analysis revealed a complex bacterial community in the cancer patients that was not significantly different from the controls. Sequencing of 140 clones revealed 102 phylotypes, with representatives from five bacterial phyla (Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria and Fusobacteria). The data revealed a relatively low abundance of H. pylori and showed that the gastric cancer microbiota was instead dominated by different species of the genera Streptococcus, Lactobacillus, Veillonella and Prevotella. The respective role of these species in development of gastric cancer remains to be determined.

    Curcumin, is a polyphenol from Curcuma longa (turmeric plant), is a polyphenol that belongs to the ginger family which has long been used in Ayurveda medicines to treat various diseases such as asthma, anorexia, coughing, hepatic diseases, diabetes, heart diseases, wound healing and Alzheimer's. Various studies have shown that curcumin has anti-infectious, anti-inflammatory, anti-oxidant, hepatoprotective, thrombosuppressive, cardio protective, anti-arthritic, chemo preventive and anti-carcinogenic activities. It may suppress both initiation and progression stages of cancer. Anticancer activity of curcumin is due to negative regulation of inflammatory cytokines, transcription factors, protein kinases, reactive oxygen species (ROS) and oncogenes. This review focuses on the different targets of curcumin to treat cancer.

    Full Text Available Introduction & Objective: Reducing in muscle strength of the shoulder girdle is a side effect of breast cancer treatment. The aim of this study was to determine the effect of 4 weeks of resistance and mobility training on the shoulder girdle strength of women with breast cancer. Materials & Methods: In this randomized clinical trial study twenty-seven postmenopausal women with breast cancer (mean age, 51±5.96 years, (mean height, 158.08±7.2 cm, (mean weight, 63.08±11.06 kg who underwent surgery, chemotherapy and radiation therapy, were purposefully selected and divided into two groups of intervention and control. Intervention group performed 4 weeks (4 sessions per week of resistance training with flex-band and stretch training at home, but the control group did not participate in any sports or physical program. Muscle strength before and after intervention was measured using a handheld dynamometer. The data were analyzed using ANCOVA. Results: Significant differences were seen between intervention and control groups in shoulder flexion, scapula abduction and upward rotation, shoulder internal rotation, shoulder external rotation, shoulder horizontal adduction and scapula depression and adduction strength, as all strength variables increased after 4 weeks exercise. Conclusion: Since strength plays an important role in ADL performance and shoulder girdle function in breast cancer survivors, it seems that muscle strength improvement following combined home based exercise program can help patients after treatment to easier and faster rehabilitation.

    Pregnancy, parity, and circulating steroid hormone levels are associated with risk of breast cancer, but little is known about hormone concentrations during pregnancy and subsequent breast cancer risk. We evaluated early pregnancy (pregnancies registered in Finland since 1983. Individuals with samples collected in the first pregnancy leading to a live birth were eligible. Breast cancer cases (n = 1,199) were identified through linkage with the Finnish Cancer Registry; 2,281 matched controls were selected using incidence density sampling. ORs were calculated using conditional logistic regression. Hormone concentrations were not associated with breast cancer overall. Estradiol was positively associated with risk of breast cancer diagnosed age hormones were associated with increased risk of estrogen receptor (ER)- and progesterone receptor (PR)-negative tumors in women age hormones and ER(+)/PR(+) disease. These data suggest a positive association between high concentrations of early pregnancy steroid hormones and risk of ER(-)/PR(-) breast cancer in women diagnosed age pregnancy hormones and risk of steroid receptor-negative cancers is needed to further characterize this association.

  11. Homeostasis 5: nurses as external agents of control in breast cancer.

    Science.gov (United States)

    Clancy, John; McVicar, Andrew

    Breast cancer is caused by a homeostatic imbalance of cell division. Healthcare practitioners need to understand cellular activities to appreciate the physiological basis of health (homeostasis), the pathophysiological basis of illness and the physiological rationale of healthcare. Cells are the 'basic unit of life' (Clancy and McVicar, 2011a). This article describes normal cell division and the anatomy and physiology of the breast and, using a case study, will show how breast cancer is a homeostatic imbalance of cell division. There are analogies between the components of homeostasis and the components of the nursing (healthcare) process (Clancy and McVicar, 2011b) in the condition of breast cancer. After reading this article, nurses should be able to: understand that breast cancer is a cellular hence chemical imbalance that causes uncontrollable mitotic division of breast cells; understand how the cell cycle of cancer cells differs from that of normal cells; identify nature-nurture interactions involved in the aetiology of breast cancer; understand that when caring for people with breast cancer, health professionals including oncology nurses are acting as external agents of homeostatic control as the patient 'recovers' from breast cancer, and also to some extent when reducing signs and symptoms, hence quality of life, by providing palliative care.

    Breast cancer (BC) is the leading cancer among women worldwide and in 5-10 % of cases is of hereditary origin, mainly due to BRCA1/2 mutations. Therefore, the German Consortium for Familial Breast and Ovarian Cancer (HBOC) with its 15 specialized academic centers offers families at high risk for familial/hereditary cancer a multimodal breast cancer surveillance program (MBCS) with regular breast MRI, mammography, ultrasound, and palpation. So far, we know a lot about the psychological effects of genetic testing, but we know little about risk-correlated adherence to MBCS or prophylactic surgery over time. The aim of this study was to investigate counselees' adherence to recommendations for MBCS in order to adjust the care supply and define predictors for incompliance. All counselees, who attended HBOC consultation at the University Hospital Heidelberg between July 01, 2009 and July 01, 2011 were eligible to participate. A tripartite questionnaire containing sociodemographic information, psychological parameters, behavioral questions, and medical data collection from the German consortium were used. A high participation rate was achieved among the study population, with 72 % returning the questionnaire. This study showed a rate of 59 % of full-adherers to the MBCS. Significant predictors for partial or full adherence were having children (p = 0.0221), younger daughters (p = 0.01795), a higher awareness of the topic HBOC (p = 0.01795, p breast cancer risk (p breast cancer surveillance program for women at risk for familial breast and ovarian cancer versus overscreening-a monocenter study in Germany.

    Cervical cancer is the leading malignant neoplasm in Peruvian women. This malignancy is a public health problem and several efforts were previously performed to develop cancer control plans. Geographical, cultural, structural, infrastructural and procedural barriers can limit the implementation of such strategies. Several previous studies have characterized human papilloma virus (HPV) epidemiology, where prevalence of high-risk HPV in adult females is ~12% and the prevalence in cervical cance...

    Although anemia is considered to be a contributor to intra-tumoral hypoxia and tumor resistance to ionizing radiation in cancer patients, the impact of pretreatment anemia on local control after neoadjuvant concurrent chemoradiotherapy (NACRT) and surgery for rectal cancer remains unclear. We reviewed the records of 247 patients with locally advanced rectal cancer who were treated with NACRT followed by curative-intent surgery. The patients with anemia before NACRT (36.0%, 89/247) achieved less pathologic complete response (pCR) than those without anemia (p = 0.012). The patients with pretreatment anemia had worse 3-year local control than those without pretreatment anemia (86.0% vs. 95.7%, p = 0.005). Multivariate analysis showed that pretreatment anemia (p = 0.035), pathologic tumor and nodal stage (p = 0.020 and 0.032, respectively) were independently significant factors for local control. Pretreatment anemia had negative impacts on pCR and local control among patients who underwent NACRT and surgery for rectal cancer. Strategies maintaining hemoglobin level within normal range could potentially be used to improve local control in rectal cancer patients.

    The hormesis phenomena or J-shaped dose response have been accepted as a common phenomenon regardless of the involved biological model, endpoint measured and chemical class/physical stressor. This paper first introduced a mathematical dose response model based on systems biology approach. It links molecular-level cell cycle checkpoint control information to clonal growth cancer model to predict the possible shapes of the dose response curves of Ionizing Radiation (IR) induced tumor transforma...
