Abstract
Abstract
Background and objectives
The prevalence of both atrial fibrillation (AF) and cancer are increasing especially in the elderly. The occurrence of AF in cancer may be related to comorbidities of patients, cancer treatment, or a direct tumor effect. The objectives of this study were to investigate the incidence of AF according to cancer type.
Methods
From the Korean National Health Insurance Service elderly (NHIS-elderly) cohort (age >60), we identified 67,077 patients with newly diagnosed cancer and without previous AF. Incidence rates of new onset AF were evaluated.
Results
The mean age of the cancer patients was 75.1 year and 53.5% were males. During a median follow-up period of 25 months, the incidence rate of AF among overall cancer patients was higher than that of age-sex matched non-cancer population (1.42 vs. 0.69 per 100 person-years, respectively). Compared with solid cancer, the risk of incident AF in patients with hematologic cancer was significantly higher (hazard ratio [HR]: 1.53, 95% confidence interval [CI]: 1.39–1.72, p<0.001). Among patients with solid cancer, thoracic (lung cancer, esophageal cancer, mediastinal cancer, etc.) and breast cancer was associated with a higher risk of AF incidence compared with other solid cancer (HR: 1.64, 95% CI: 1.53–1.76, p<0.001).
Conclusions
Cancer was associated with an increased incidence of AF. Hematologic cancer was associated with higher risk of AF incidence than solid cancer. Among solid cancer, thoracic and breast cancer was most strongly associated with the risk of AF incidence.

Abstract
BACKGROUND Despite a growing need for designing and monitoring health information sites through comprehensive examination of the various elements of website quality, there is little research that systematically models and presents such examinations. OBJECTIVES Applying the updated DeLone and McLean Model of Information Systems Success, this research aimed to examine how health information sites' information quality, system quality, and service quality lead to user satisfaction and perceived benefits. METHODS This research was conducted in a specific context of the National Health Information Portal (NHIP), a governmental health information site in South Korea. We conducted online survey in 2017, with 506 adults from the NHIP consumer panel. Data were analyzed using a confirmatory factor analysis, hierarchical ordinary least squares regression, and bootstrapping approach for a mediation test. RESULTS Of the three quality factors, information quality had significant associations with all outcome variables: user satisfaction, intention to reuse the site, and perceived benefits of site use in health settings. There were also indirect paths from information quality to perceived benefits, one mediated through intention and the other mediated through satisfaction and then intention. Service quality had a significant association with user satisfaction, and its impact on perceived benefits occurred indirectly through user satisfaction and intention in serial. By contrast, the role of system quality received no empirical support. IMPLICATIONS The results offer theoretical and practical implications for how to enhance the effectiveness of online health information sites.

Abstract
Lay public's concerns around health and health information are increasing. In response, governments and government agencies are establishing websites to address such concerns and improve health literacy by providing better access to validated health information. Since 2011, the Korean government has constructed the National Health Information Portal (NHIP) website run in collaboration with the Korean Academy of Medical Sciences (KAMS). This study therefore aimed to 1) examine consumer use of NHIP, with respect to the usage patterns, evaluation on health information provided, and perceived effectiveness of the site; and 2) identify factors that may impact perceived effectiveness of the site. An online survey was conducted with 164 NHIP users, recruited through a popup window on the main screen of the portal website from October to November 2015. The significant predicting factors supported by the data include the relevance of health information on the site, the usefulness of information in making health decisions, and the effective visualization of information. These factors can inform future efforts to design more effective health information websites, possibly based on metadata systems, to further advance the lay public's information seeking and health literacy.

Abstract
OBJECTIVE Emerging adulthood (EA) is an important yet overlooked period for developing long-term health behaviors. During these years, emerging adults adopt health behaviors that persist throughout life. This study applies the Integrative Model of Behavioral Prediction (IMBP) to examine the role of childhood parental communication in predicting engagement in healthful eating during EA. METHODS Participants included 239 college students, ages 18 to 25, from a large university in the southern United States. Participants were recruited and data collection occurred spring 2012. Participants responded to measures to assess perceived parental communication, eating behaviors, attitudes, subjective norms, and behavioral control over healthful eating. SEM and mediation analyses were used to address the hypotheses posited. RESULTS Data demonstrated that perceived parent-child communication - specifically, its quality and target-specific content - significantly predicted emerging adults' eating behaviors, mediated through subjective norm and perceived behavioral control. CONCLUSION This study sets the stage for further exploration and understanding of different ways parental communication influences emerging adults' healthy behavior enactment.

Abstract
How the news media cover cancer may have profound significance for cancer prevention and control; however, little is known about the actual content of cancer news coverage in Korea. This research thus aimed to examine news portrayal of specific cancer types with respect to threat and efficacy, and to investigate whether news portrayal corresponds to actual cancer statistics. A content analysis of 1,138 cancer news stories was conducted, using a representative sample from 23 news outlets (television, newspapers, and other news media) in Korea over a 5-year period from 2008 to 2012. Cancer incidence and mortality rates were obtained from the Korean Statistical Information Service. Results suggest that threat was most prominent in news stories on pancreatic cancer (with 87% of the articles containing threat information with specific details), followed by liver (80%) and lung cancers (70%), and least in stomach cancer (41%). Efficacy information with details was conveyed most often in articles on colorectal (54%), skin (54%), and liver (50%) cancers, and least in thyroid cancer (17%). In terms of discrepancies between news portrayal and actual statistics, the threat of pancreatic and liver cancers was overreported, whereas the threat of stomach and prostate cancers was underreported. Efficacy information regarding cervical and colorectal cancers was overrepresented in the news relative to cancer statistics; efficacy of lung and thyroid cancers was underreported. Findings provide important implications for medical professionals to understand news information about particular cancers as a basis for public (mis)perception, and to communicate effectively about cancer risk with the public and patients.

Abstract
BACKGROUND Little is known about the news coverage of cancer risk factors in Korea. This study aimed to examine how the news media encompasses a wide array of content regarding cancer risk factors and related cancer sites, and investigate whether news coverage of cancer risk factors is congruent with the actual prevalence of the disease. MATERIALS AND METHODS A content analysis was conducted on 1,138 news stories covered during a 5-year period between 2008 and 2012. The news stories were selected from nationally representative media in Korea. Information was collected about cancer risk factors and cancer sites. RESULTS Of various cancer risk factors, occupational and environmental exposures appeared most frequently in the news. Breast cancer was mentioned the most in relation to cancer sites. Breast, cervical, prostate, and skin cancer were overrepresented in the media in comparison to incidence and mortality cases, whereas lung, thyroid, liver, and stomach cancer were underrepresented. CONCLUSIONS To our knowledge, this research is the first investigation dealing with news coverage about cancer risk factors in Korea. The study findings show occupational and environmental exposures are emphasized more than personal lifestyle factors; further, more prevalent cancers in developed countries have greater media coverage, not reflecting the realities of the disease. The findings may help health journalists and other health storytellers to develop effective ways to communicate cancer risk factors.

Abstract
An appropriate level of risk perception should be a critical issue in modern "risk society." There have been many studies on the influences on risk perception. This study investigates whether risk communication scholar Dr. Peter Sandman's outrage factors intensify journalistic attention to health risks from food consumption. A content analysis of a health institution's press releases was conducted to examine 15 outrage factors of food risks conveyed in the governmental risk communication. In addition, the news stories covering the food risks informed by the press releases were calculated to evaluate the relation between outrage factors of a risk and the number of news stories covering the risk. Results showed that controllability was the most salient outrage factor, followed by trust, voluntariness, familiarity, and human origin; the greater the outrage score of a risk, the more news stories of the risk. For individual outrage factors, a risk with an implication of catastrophic potential was associated with an increase of news stories. Food providers' distrustful behaviors also influenced journalistic attention to the food risks. The implication of the findings to health message designers is discussed.

Abstract
Despite existing research identifying psychological benefits of patients' interpersonal competence in various contexts, little longitudinal research has addressed underlying mechanism(s). To address this limitation, we examined both the cross-sectional and longitudinal associations between cancer patients' communication competence in close relationships and psychological well-being, as well as the mediating role of coping efforts. Data came from a larger project with women with breast cancer (N = 661), recruited from April 2005 to May 2007 at three large university-affiliated cancer centers in the U.S. to study the effects of an Internet-based system providing patients and families with a range of services. The present study focused on survey data at baseline, 6 weeks, and 12 weeks after the intervention (controlling for the possible effects of the intervention). Results from both cross-sectional and longitudinal analyses indicated that competence in open communication between patients and their close support persons had a positive association with patients' psychological well-being and that approach coping efforts partially mediated this association. We discussed the implications and limitations of the study.

Abstract
Despite the benefits and growing availability of online cancer support groups, many breast cancer patients still do not actively participate in them. To better understand cancer patients' online information- and support-seeking behaviors, this study explores how various social and psychological characteristics predict different levels of engagement with an online breast cancer support group: posters, lurkers, and nonusers. The study sample included 231 recently diagnosed breast cancer patients. Data included baseline survey scores of demographic, disease-related, and psychosocial factors and automatically collected discussion group use data over the 4-month intervention. Patterns of engagement with the cancer support group differed according to the patients' characteristics, suggesting that (a) cancer patients have very different orientations to and engagement with an online support group, and (b) deficits in social and psychological resources may not be barriers to participation in a cancer support group, but rather motivators to interact with other patients. The authors discuss the theoretical and practical implications of their findings.

Abstract
Despite much research on the beneficial effects of written disclosure, relatively little attention has been paid to specifying the mechanism underlying the effects. Building upon the two theoretical models (the cognitive adaptation model and the emotional exposure-habituation model), this research focused on two aspects of disclosure content-insights and emotions-and examined how women with breast cancer benefit from written disclosure in online support groups. Using survey data collected at baseline and after four months and messages posted in bulletin-board-type online groups in between, we analyzed how the content of disclosive messages predicted health outcomes. Disclosure of insights led to greater improvements in health self-efficacy, emotional well-being, and functional well-being, which was mediated by lowered breast cancer concerns. Disclosure of negative emotions did not have main effects on health outcomes; instead, it weakened the unfavorable association between concerns at baseline and functional well-being at follow-up. Our findings support both theoretical models, but in regard to different aspects of disclosure content.

Abstract
Provider-patient communication is an important factor influencing patients' satisfaction and health outcomes. This study draws upon the uses and gratification theory to examine how individuals' perception of communication with healthcare providers is associated with their Internet use for health-related activities. Using the data from the 2007 Health Information National Trends Survey (HINTS), we found that as individuals perceived their communication with providers to be less patient-centered, they were more likely to engage in various types of online health activities, such as using websites for healthy lifestyles, searching for healthcare providers, and seeking health information. Trust in online health information was also found to be a significant predictor of online health activities. The results of this study emphasized the important role of provider-patient communication in motivating individuals to turn to the Internet for health purposes.

Abstract
This study applies the knowledge gap hypothesis to the specific domain of Internet use for cancer information. In particular, this study examines disparities in online information seeking by education and ethnicity, and subsequent gaps in cancer knowledge. Perceived risk of cancer and ease of connection to the Internet are concerned as contingent factors influencing knowledge gaps. A subsample of the 2003 Health Information National Trends Survey-t-hose who have ever been online--was analyzed. Data supported the hypothesis that high education groups and White Americans were more likely to use the Internet for cancer information than were their counterparts, and online information seeking enlarged to some degree the cancer knowledge gaps between education groups. Perceived cancer risk had a weak but significant three-way interaction effect with ethnicity and online seeking on cancer knowledge, which suggests the importance of motivation in attenuating the knowledge gaps. The moderating role of ease of connection to the Internet was not supported. Discussion about the findings and further suggestions are offered.

Abstract
Previous research on cancer information focused on active seeking, neglecting information gathered through routine media use or conversation ("scanning"). It is hypothesized that both scanning and active seeking influence knowledge, prevention, and screening decisions. This study uses Health Information National Trends Survey (HINTS, 2003) data to describe cancer-related scanning and seeking behavior (SSB) and assess its relationship with knowledge, lifestyle behavior, and screening. Scanning was operationalized as the amount of attention paid to health topics, and seeking was defined as looking for cancer information in the past year. The resulting typology included 41% low-scan/no-seekers; 30% high-scan/no-seekers; 10% low-scan/seekers, and 19% high-scan/seekers. Both scanning and seeking were significantly associated with knowledge about cancer (B=.36; B=.34) and lifestyle choices that may prevent cancer (B=.15; B=.16) in multivariate analyses. Both scanning and seeking were associated with colonoscopy (OR = 1.38, for scanning and OR=1.44, for seeking) and with prostate cancer screening (OR=4.53, scanning; OR=10.01, seeking). Scanning was significantly associated with recent mammography (OR=1.46), but seeking was not. Individuals who scan or seek cancer information are those who acquire knowledge, adopt healthy lifestyle behaviors, and get screened for cancer. Causal claims about these associations await further research.

Abstract
In addition to being the major site of cerebrospinal fluid formation, the choroid plexus epithelium emerges as an important source of polypeptides in the brain. Physiologically regulated release of some polypeptides synthesized by the choroid plexus has been shown. The molecular mechanisms underlying this polypeptide secretion have not been characterized, however. In the present study, synaptosome-associated protein of 25 kDa and vesicle-associated membrane protein, two membrane fusion proteins playing a critical role in exocytosis in neurons and endocrine cells, were found to be expressed in the choroid plexus epithelium. It was also shown that in choroidal epithelium, synaptosome-associated protein of 25 kDa and vesicle-associated membrane protein stably interact. Two members of the vesicle-associated membrane protein family, vesicle-associated membrane protein-1 and vesicle-associated membrane protein-2, were expressed in the rat choroid plexus at the messenger RNA and protein level. However, their newly discovered isoforms, vesicle-associated membrane protein-1b and vesicle-associated membrane protein-2b, produced by alternative RNA splicing, were not detected in choroidal tissue. Immunohistochemistry demonstrated that vesicle-associated membrane protein is confined to the cytoplasm of choroidal epithelium, whereas synaptosome-associated protein of 25 kDa is associated with plasma membranes, albeit with a varied cellular distribution among species studied. Specifically, in the rat choroid plexus, synaptosome-associated protein of 25 kDa was localized to the basolateral membrane domain of choroidal epithelium and was expressed in small groups of cells. In comparison, in ovine and human choroidal tissues, apical staining for synaptosome-associated protein of 25 kDa was found in the majority of epithelial cells. These species-related differences in cellular synaptosome-associated protein of 25 kDa distribution suggested that the synaptosome-associated protein of 25 kDa homologue, synaptosome-associated protein of 23 kDa, is also expressed in the rat choroid plexus, which was confirmed by reverse-transcriptase polymerase chain reaction. Our findings suggest that synaptosome-associated protein of 25 kDa and vesicle-associated membrane protein are involved in secretion of polypeptides from the choroid plexus epithelium. The presence of synaptosome-associated protein of 25 kDa and its homologue as well as multiple isoforms of vesicle-associated membrane protein in choroidal epithelium may play a role in the apical versus basolateral targeting of secretory vesicles.

Abstract
Wurtzite ZnO nanocrystals capped with trioctylphosphine oxide or alkylamines are synthesized and characterized. These ZnO nanocrystals can be made n-type either by electron transfer doping from reducing species in solution or by above band gap photoexcitation with a UV lamp. The n-type nanocrystals exhibit a strong intraband infrared absorption, an extensive bleach of the interband band-edge absorption, and a complete quenching of the photoluminescence.

Abstract
Incorporating nanocrystals into future electronic or optoelectronic devices will require a means of controlling charge-injection processes and an understanding of how the injected charges affect the properties of nanocrystals. We show that the optical properties of colloidal semiconductor nanocrystal quantum dots can be tuned by an electrochemical potential. The injection of electrons into the quantum-confined states of the nanocrystal leads to an electrochromic response, including a strong, size-tunable, midinfrared absorption corresponding to an intraband transition, a bleach of the visible interband exciton transitions, and a quench of the narrow band-edge photoluminescence.

Abstract
Colloidal semiconductor nanocrystals combine the physical and chemical properties of molecules with the optoelectronic properties of semiconductors. Their colour is highly controllable, a direct consequence of quantum confinement on the electronic states. Such nanocrystals are a form of 'artificial atoms' (ref. 4) that may find applications in optoelectronic systems such as light-emitting diodes and photovoltaic cells, or as components of future nanoelectronic devices. The ability to control the electron occupation (especially in n-type or p-type nanocrystals) is important for tailoring the electrical and optical properties, and should lead to a wider range of practical devices. But conventional doping by introducing impurity atoms has been unsuccessful so far: impurities tend to be expelled from the small crystalline cores (as observed for magnetic impurities), and thermal ionization of the impurities (which provides free carriers) is hindered by strong confinement. Here we report the fabrication of n-type nanocrystals using an electron transfer approach commonly employed in the field of conducting organic polymers. We find that semiconductor nanocrystals prepared as colloids can be made n-type, with electrons in quantum confined states.

Abstract
Perturbations of the insulin-like growth factor (IGF) axis, including the autocrine production of IGFs, IGF binding proteins (IGFBPs) and IGFBP proteases such as prostate specific antigen (PSA), and cathepsin D have been identified in prostate, lung and breast cancer cells and tissues. Serum IGFBP-3 levels have been found to be negatively correlated to the risk of cancer. Interestingly, IGFBP-3 is a potent inhibitor of IGF action and also mediates apoptosis via an IGF-independent mechanism. Recent case-control studies have found an approximately 10% increase in the serum levels of IGF-I in patients with prostate, breast and lung cancers, which are among the most frequently diagnosed cancers. While the studies indicate an association between serum IGF-I levels and cancer risk, causality has not been established. Thus, serum IGF-I level may actually be a confounding variable, serving as a marker for autocrine tissue IGF-I production. Growth hormone (GH) therapy raises both IGF-I and IGFBP-3 levels in serum. However, the role of GH in controlling prostate, breast and lung growth and carcinogenesis remains unclear from animal studies. Increased GH levels as seen in acromegaly have been associated with benign prostatic hyperplasia but not with prostate, breast or lung cancers, although colon cancer mortality may be increased. Should serum IGF-I levels be proven to play a causal role in the pathogenesis of cancer, interpreting the risk associated with therapies such as GH replacement must take into account both the duration of exposure and the risk magnitude associated with the degree of serum IGF-I elevation. Since GH-deficient patients often have a subnormal IGF-I serum level, which normalizes on therapy, their cancer risk on GH therapy probably does not increase substantially above that of the normal population. Until further research in the area dictates otherwise, ongoing surveillance and routine monitoring of IGF-I levels in GH recipients should become standard of care.

Abstract
The epidermis is a stratified squamous epithelium composed primarily of keratinocytes that become postmitotic and undergo sequential changes in gene expression during terminal differentiation. The expression of the transcription factor CCAAT/enhancer binding protein beta (C/EBPbeta) within mouse epidermis and primary keratinocytes has recently been described; however, the function of C/EBPbeta within the epidermal keratinocyte is unknown. We report here that transient transfection of mouse primary keratinocytes with a C/EBP-responsive promoter-reporter construct resulted in a sevenfold increase in luciferase activity when keratinocytes were switched to culture conditions that induce growth arrest and differentiation. Forced expression of C/EBPbeta in BALB/MK2 keratinocytes inhibited growth, induced morphological changes consistent with a more differentiated phenotype, and upregulated two early markers of differentiation, keratin 1 (K1) and keratin 10 (K10) but had a minimal effect on the expression of late-stage markers, loricrin and involucrin. Analysis of the epidermis of C/EBPbeta-deficient mice revealed a mild epidermal hyperplasia and decreased expression of K1 and K10 but not of involucrin and loricrin. C/EBPbeta-deficient primary keratinocytes were partially resistant to calcium-induced growth arrest. Analysis of terminally differentiated spontaneously detached keratinocytes or those induced to differentiate by suspension culture revealed that C/EBPbeta-deficient keratinocytes displayed striking decreases in K1 and K10, while expression of later-stage markers was only minimally altered. Our results demonstrate that C/EBPbeta plays an important role in the early events of stratified squamous differentiation in keratinocytes involving growth arrest and K1 and K10 expression.

Abstract
President Clinton's Health Security Act proposes the formation of large scale health plans with improved quality assurance. Dental radiography consumes 4% ($1.2 billion in 1990) of total dental expenditure yet regular systematic office quality assurance is not performed. A pilot automated method is described for assessing density of exposed film and fogging of unexposed processed film. A workstation and camera were used to input intraoral radiographs. Test images were produced from a phantom jaw with increasing exposure times. Two radiologists subjectively classified the images as too light, acceptable, or too dark. A computer program automatically classified global grey level histograms from the test images as too light, acceptable, or too dark. The program correctly classified 95% of 88 clinical films. Optical density of unexposed film in the range 0.15 to 0.52 measured by computer was reliable to better than 0.01. Further work is needed to see if comprehensive centralized automated radiographic quality assurance systems with feedback to dentists are feasible, are able to improve quality, and are significantly cheaper than conventional clerical methods.
