We further delineated that EGFR/MEK/ERK/IKK/mTORC1 is the key upstream pathway of NF-κB activation in immortalized NPE cells. Elucidation of events underlying immortalization of NPE cells may provide insights into early events in pathogenesis of NPC. The identification of NF-κB activation and elucidation of its activation mechanism in immortalized NPE cells may reveal novel therapeutic targets for treatment and prevention of NPC.
On 31 December 2013, the US Preventive Services Task Force rated low-dose computed tomography (LDCT) for lung cancer screening as level 'B' recommendation. Yet, lung cancer screening implementation remains controversial, particularly when considering its cost-effectiveness. The aim of this work is to investigate the cost-effectiveness of LDCT screening program for lung cancer by performing a systematic literature review.
We reviewed the published economic evaluations of LDCT in lung cancer screening. MEDLINE, ISI Web of Science and Cochrane databases were searched for literature retrieval up to 31 March 2015. Inclusion criteria included studies reporting an original full economic evaluation; reports presenting the outcomes as Quality-Adjusted Life Years (QALYs) gained or as Life Years Gained.
Nine economic evaluations met the inclusion criteria. All the cost-effectiveness analyses included high risk populations for lung cancer and compared the use of annual LDCT screening with no screening. Seven studies reported an incremental cost-effectiveness ratio below the threshold of US$ 100 000 per QALY gained.
Cost-effectiveness of LDCT screening for lung cancer is an highly debatable issue. Currently available economic evaluations suggest the cost-effectiveness of LDCT for lung cancer screening compared with no screening and indicate that the implementation of LDCT should be considered when planning a national lung cancer screening program. Additional economic evaluations, especially from a societal perspective and in an EU-setting, are needed.

Back pain (BP) represents a widespread public health problem in Europe. The morbidity depends on several indicators, which must be investigated to discover risk groups. The examination of trends in socioeconomic developments should ensure a better understanding of the complex link between socioeconomic-status and BP. Therefore, the role of social inequalities for BP has been investigated among Austrian subpopulations over a 24-year period.
Self-reported data from nationally representative health surveys (1983-2007) were analyzed and adjusted for self-report bias (N=121 486). Absolute changes (ACs) and aetiologic fractions (AF) were calculated to measure trends. To quantify the extent of social inequality, the relative index of inequality was computed based on educational levels.
The prevalence of BP nearly doubled between 1983 and 2007. When investigating educational groups, subjects with low educational level were most prevalent. Obese persons generally showed higher rates of BP than non-obese subjectsf effective approaches to BP, in combination with target group-specific interventions focusing on educational status, is recommended.
The diagnosis-related group-based prospective payment programme was introduced in Korea in 1997 as a pilot programme to control health spending. In July 2013, the programme was implemented throughout the nation. The aim of our study is to evaluate the relationship between quality of care and market competition following the introduction of the new payment system in Korea.
We conduct an observational analysis using National Health Insurance claim data from 2011 to 2014. We analyse data on readmission within 30 days, length of stay, and number of outpatient visits for 1742 hospitals and 821 912 cases. We use a generalized estimating equation model to evaluate readmission within 30 days and number of outpatient visits and a multi-level regression model to assess length of stay.
Total readmission within 30 days is 10 727 (1.3%). High competition areas present a lower risk of readmission [odds ratio (OR) 0.95, P 0.0277], a longer length of stay (1%, P < 0.0001), and an increased number of outpatient visits (Relative Risk 1.11, P 0.0011) as compared with moderate competition areas. Risk of readmission is higher in low competition areas as compared with moderate competition areas (OR 1.21, P < 0.0001).
The effects of the introduction of the new payment system differed by degree of market competition. Thus, evaluation about the effect of new payment system on hospital performance should be measured in combination with the degree of hospital market structure.

Colorectal cancer (CRC) is one of the most common cancers in men and women. CRC screening programmes have been implemented in various countries. However, the participation rate remains disappointingly low. For a screening method to be beneficial, high participation rates are essential. Therefore, understanding the factors that are associated with CRC screening and follow-up adherence is necessary. In this systematic review, factors studied in literature were identified that are associated with CRC screening adherence.
A systematic search in PUBMED, EMBASE and COCHRANE was performed to identify barriers and facilitators for CRC screening adherence. Study characteristics were summarized and analysed.
Seventy-seven papers met the inclusion criteria to be applicable for review. Female gender, younger participants, low level of education, lower income, ethnic minorities and not having a spouse were the most frequently reported barriers. Health provider characteristics, such as health insurance and a usual source of care were also frequently reported barriers in CRC screening adherence. Disparities were found in weight, employment status and self-perceived health status.
Barriers and facilitators of CRC screening participation are frequently reported. Understanding these factors is the first step to possibly modify specific factors to increase CRC screening participation rate.

The aim of this study was to determine sex differences in the prevalence of cardiovascular health (CVH) metrics according to the CVH status.
The cross-sectional, population-based study involved 2250 women and 1920 men aged ≥18 years that participated in the 2010 National Health Survey in the Republic of Srpska, Bosnia and Herzegovina. Prevalence of CVH behaviours (smoking, body mass index, physical activity, diet), CVH factors (cholesterol, fasting blood glucose and blood pressure, plus smoking) and ideal CVH were estimated according to the American Heart Association criteria for ideal, intermediate and poor levels. Association between sex and ideal CVH categories was analyzed with multivariable logistic regression analysis across three age stratums.
A higher prevalence of ideal CVH metrics was seen in women for smoking status, body mass index, healthy diet score and blood pressure, and in men for physical activity and total cholesterol. Women from all age groups had better CVH behaviours (odds ratio [OR] = 1.40 for the youngest; OR = 2.05 for middle-aged; and OR = 2.03 for older-aged women), while only women from the youngest age group had better CVH factors (OR = 5.09). In line with this, ideal overall CVH prevailed in younger and middle-aged women in comparison to men of the same ages (OR = 3.01 and OR = 2.25, respectively), while disappeared in older ones.
Significant differences in the prevalence of CVH metrics between men and women in the Republic of Srpska should be considered in cardiovascular disease prevention.

'Han-ji' is the name of a traditional paper used widely in Korea in construction, textile, craftworks and many household items but before now it has not been used for filtration purpose. Seeking for the utilization of this abundant natural material, this study aims to develop a fabrication process for the traditional paper to be used as a filter for dust filtration, and evaluate the performance by lab-scale experiments. To create pores in the paper, cellulose pulp was pretreated using several methods such as TEMPO oxidation and enzyme hydrolysis, or freeze dried with an alcoholic freezing medium, t-butyl alcohol, instead of water. The filters were characterized and their dust removal performance was tested at a lab scale while also monitoring pressure loss. Chemical oxidation and enzymatic pretreatment were helpful in fabricating a homogeneous filter but would not remove fine-dust particles because of its loose, enlarged pores. The best removal efficiency was observed with filters that were not pretreated but in which water had been exchanged with t-butyl alcohol before freeze-drying. The filter attained a dust removal efficiency higher than 99% over the entire experimental period, with a pressure loss of less than 230 Pa, at a 6.67 (cm3/s)/cm2 air-to-cloth ratio.The number of notified syphilis cases in Tokyo has more than doubled in recent years. The number of reported primary and secondary syphilis cases increased from 108 cases (0.8 per 100,000 population) in 2007 to 245 cases in 2013 (1.9 per 100,000 population). selleck chemicals llc During this period, the majority of cases was male (905/1,024), and the recent increase among primary and secondary syphilis cases was attributed to the increase among males (90/108 [83%] cases in 2007 to 218/245 [89%] cases in 2013); men aged 20-49 years contributed most to the increase, with those aged 30-34 years having the highest notification rate in 2013. Male-to-male transmission was the primary route of infection reported, and men who have sex with men (MSM) accounted for nearly 80% of male cases in 2013. Syphilis appears to be reemerging in Tokyo, and reducing the risk of acquiring syphilis among MSM aged 20-49 years should be a public health priority in Tokyo.Human rotavirus samples from 54 children with acute gastroenteritis in Myanmar in 2011 were subjected to reverse transcription-PCR to determine their G and P types. On G typing, G2 (24/54; 44.4%) was found to be the most prevalent, followed by G12 (17/54; 31.5%) and G1 (1/54; 1.9%). Mixed cases with G2 and G12 were found in 12 of the 54 (22.2%) samples. On P typing, P[4] was found to be the most predominant (29/54; 53.7%), followed by P[8] (17/54; 31.5%) and P[6] (4/54; 7.4%). Mixed cases with P[4] and P[8] were detected in 4 of 54 (7.4%) samples. Thus, occurrence of G2 and unusual G12 in high proportions was characteristic of human rotaviruses in Myanmar in this study setting.
