rove access to valve interventions are necessary if progress is to be made toward reducing, and eventually eliminating, the burden of these highly treatable diseases.This study examines knowledge of physical activity (PA) guidelines for cancer prevention and beliefs of the role of PA in preventing cancer as correlates of moderate-to-vigorous intensity PA (MVPA) behaviour among adults. Measures assessing socio-demographic characteristics, knowledge of PA guidelines, and PA beliefs and behaviour were completed online by 654 adults (Mage = 36.92 ± 14.61 years) with no history of cancer. Data were analyzed descriptively and using unadjusted and adjusted logistic regression analysis. Approximately half the sample was aware of PA guidelines for cancer prevention (49.24%) and believed that PA was extremely effective in reducing the risk of developing cancer (48.93%). Knowledge of PA guidelines for cancer prevention was associated with a greater likelihood of being active (unadjusted odds ratio [OR] 1.66, 95% confidence interval [95% CI] 1.18-2.34; p less then .01; adjusted OR 2.05, 95% CI 1.36-3.11; p less then .001). Beliefs regarding the effectiveness of PA in preventing cancer was not associated with a greater likelihood of being active. There is a lack of awareness of current PA guidelines for cancer prevention. Experimental studies are needed to further explore if increasing adults’ knowledge of PA guidelines for cancer prevention can enhance PA levels.Marginal zone lymphoma (MZL) belongs to the group of indolent B-cell non-Hodgkin’s lymphomas, which is characterized by an indolent course. In this mostly elderly patient population, the development of chemotherapy-free approaches is of particular interest. In this situation, single-agent treatment with the next-generation anti-CD20 antibody obinutuzumab is an attractive approach, which promises high efficacy without major toxicity. We describe here an open-label, multicentric Phase II trial evaluating the efficacy and safety of obinutuzumab in de novo MZL patients, who are treatment naive for systemic therapy and not eligible for or failed local treatment. (clinicaltrials.gov identifier NCT03322865).Objectives Racial/ethnic minority women have disproportionately lower breast cancer survival rates compared to white women. As minorities in the US are exposed to higher levels of discrimination, and exposure to discrimination has been associated with shorter telomere lengths (TLs), we investigated the association between perceived everyday discrimination and TL in a multiethnic sample of breast cancer survivors.Design We examined a cohort of 58 breast cancer survivors who participated in a pilot study to investigate biological stress. Participants were drawn from the Equality in Breast Cancer Care (EBCC) study and were asked to provide saliva samples for DNA extraction. Ordinary least squares linear regression was used to derive regression coefficients (β) and 95% confidence intervals (CI).Results Higher levels of everyday discrimination were associated with longer TLs (eβ = 1.04, CI 1.01-1.07), adjusting for age, race/ethnicity, breast cancer stage, and breast cancer subtype. Luminal B subtypes were associated with longer telomeres relative to luminal A, while African Americans were less likely than Whites to have longer telomeres.Conclusions Further research, particularly longitudinal studies, is needed to understand how discrimination, and other social stressors, impact biological stress and health outcomes.Objective Race disparities exist in bone metastasis (BM) development and survival in lung cancer (LC) patients. The Surveillance, Epidemiology, and End Results (SEER) database was used to investigate different patterns of BM development and survival in different races.Design LC patients with BM were identified from the database from 2010 to 2014. Risk factors were investigated by univariable and multivariable logistic regression. Potential factors for prognosis were evaluated by univariable and multivariable Cox regression.Results Asian and Pacific Islander (API) patients presented the highest prevalence of BM (24.6%), followed by white (20.7%) and black patients (19.9%) (χ2 = 78.74; p  less then  .001). After adjusting for the demographic and clinical factors, API race was independently associated with a high risk of BM development. The median survival times for the API, white and black LC patients with BM were 16 months (95% CI 15.2-16.8), 11 months (95% CI 10.9-11.1) and 10 months (95% CI 9.7-10.3), respectively, with significant differences (p  less then  .001). Multivariable Cox regression showed that API race was positively associated with greater overall survival compared with white and black patients. Male gender, larger tumor size, lymph node involvement, lower tumor differentiated grade, and the presence of lung, liver and brain metastases were independently associated with a high risk of developing BM and worse survival with LC across all races. Age, income, insurance and histological types had different impacts on BM among different races.Conclusion Homogeneous and heterogeneous associated factors for BM were revealed among different races. Individualized screening and treatment should be performed race-specifically.In the United States, through nation-wide discussions, the procedures for handling allegations of research misconduct are now well established. Procedures are geared toward carefully treating both complainants and respondents fairly in accordance within the US framework. Other countries, which have their own cultural and legal framework, also need fair and legally compatible procedures for conducting investigations of allegations of research misconduct. Given the rapid growth of international collaboration in research, it is desirable to have a global standard, or common ground, for misconduct investigations. Institutions need clear guidance on important subjects such as what information should be included in the investigation reports, how the investigation committee should be organized once research misconduct allegation has been received, how to conduct the investigation, how the data and information obtained should be taken as evidence for vs. against misconduct, and what policies the investigation committee should follow. We explore these issues from the viewpoint of members of committees investigating accusations of research misconduct (hereafter referred to as „investigation committees”) as well as persons overseeing the committees in Japan. We hope to engender productive discussions among experts in misconduct investigations, leading to a formulation of international standards for such investigation.To analyze the biomechanical stability of a redesigned cage, a new lateral plate and the effect of length of cage in CLIF, an L4-L5 finite element model was performed. Six different internal fixation methods were designed and operated under six conditions (Stand-alone CLIF; CLIF with unilateral pedicle screws (CLIF + UPS); CLIF with bilateral pedicle screws (CLIF + BPS); CLIF with lateral plate (CLIF + LP); CLIF with lateral plate and unilateral pedicle screws (CLIF + LP + UPS); CLIF with lateral plate and bilateral pedicle screws (CLIF + LP + BPS)). Ranges of motion (ROM) and stress distribution were evaluated. The effect of the length of cage was analyzed. The ROMs of stand-alone CLIF group and other internal fixation groups were decreased by >90% compared with the intact group. The CLIF + LP + BPS group has the minimum ROM. The CLIF + LP group has smaller ROM than stand-alone group. The stand-alone group has the minimum stress except for extension condition. The CLIF + LP model has less ROM, but a greater stress load was observed in the lateral plate. As for the length of cage, the largest stress is located at the junction between cage and distal end plate, especially in the epiphyseal ring and cortical compact. We conduct a new 'cylinder wall theory’ that the cage should be placed to cover the epiphyseal ring. We recommend the length of cage should cover the epiphyseal ring to reduce the subsidence of cage.Background This study was launched in response to an American Indian (AI) community’s concern regarding the comorbid occurrence of substance use, poor mental health, and other risk factors on sexual health. The purpose of this manuscript was to assess the relationship between alcohol use, violence, depression and STI/HIV risk behaviors on the frequency of unprotected sex acts and number of sexual partners among AI adults.Methods Specifically, this analysis examines sociodemographic characteristics, experience of sexual and physical violence, binge drinking, depression, and sexual risk taking among n = 281 AI adults ages 18-55. Regression models examine associations between the aforementioned risk factors, number of sex partners and number of unprotected sex acts, by depression status and sex, among participants.Results Frequent binge drinking predicted frequency of unprotected sex for both males and females; ever experiencing physical violence was a powerful predictor of unprotected sex for females, but not males. Ever experiencing physical violence strongly predicted having multiple sexual partners for females but was related to decreased number of sexual partners for males. Females ever experiencing sexual violence had more sexual partners; this was not observed for males. Binge drinking predicted frequency of unprotected sex acts, regardless of depression status.Discussion Interventions for AI adults seeking to reduce sexual health risk should reflect past violence victimization in sexual decision making, primarily among women. The significant role of binge alcohol use for modifying sexual decisions should be of prime focus and interventions should be personalized to address individuals’ own alcohol use patterns. Additional research should explore how binge alcohol use moderates the relationship between depression and sexual risk.New processing routes and materials for non-biocidal, antifouling (AF) coatings with an improved performance are currently much sought after for a range of marine applications. Here, the processing, physical properties and marine AF performance of a fluorinated coating based on a thermoplastic (non-crosslinked) fluorinated polymer are reported. It was found that the addition of lubricating oil and hydrodynamic drag reducing microstructures improved the AF properties substantially, i.e. the settlement of a marine biofilm, containing mixed microalgae including diatoms, was reduced to low levels. More importantly, the remaining fouling was removed from the coatings at low hydrodynamic shear rates and promising AF properties were obtained. Moreover, additional potential benefits were revealed originating from the thermoplastic nature of the coating material which might result in significant cost reductions.OBJECTIVE Diabetes mellitus is a significant risk factor for peripheral artery disease. Diabetes mellitus induces chronic states of oxidative stress and vascular inflammation that increase neutrophil activation and release of myeloperoxidase. The goal of this study is to determine whether inhibiting myeloperoxidase reduces oxidative stress and neutrophil infiltration, increases vascularization, and improves blood flow in a diabetic murine model of hindlimb ischaemia. METHODS Leptin receptor-deficient (db/db) mice were subjected to hindlimb ischaemia. Ischaemic mice were treated with N-acetyl-lysyltyrosylcysteine-amide (KYC) to inhibit myeloperoxidase. After ligating the femoral artery, effects of treatments were determined with respect to hindlimb blood flow, neutrophil infiltration, oxidative damage, and the capability of hindlimb extracellular matrix to support human endothelial cell proliferation and migration. RESULTS KYC treatment improved hindlimb blood flow at 7 and 14 days in db/db mice; decreased the formation of advanced glycation end products, 4-hydroxynonenal, and 3-chlorotyrosine; reduced neutrophil infiltration into the hindlimbs; and improved the ability of hindlimb extracellular matrix from db/db mice to support endothelial cell proliferation and migration.
