BACKGROUND: The role of surveillance breast MRI for women with mammographically dense breasts, a personal history of breast cancer (BC), atypical hyperplasia (AH), or lobular carcinoma in situ (LCIS) is unclear. We estimated the performance of annual surveillance MRI in women with a combination of these risk factors. METHODS: We performed a retrospective review of the clinical, radiological, and pathological parameters of women who received annual concurrent surveillance breast MRI and mammography between 04/2013 and 12/2015 and fulfilled all of the following criteria: 1) age <70; 2) prior diagnosis of AH, LCIS or BC; 3) heterogeneously or extremely dense breast(s); and 4) did not qualify for our provincial breast MRI high risk screening program...

The formation of robust resting cysts enables Acanthamoeba to resist harsh environmental conditions. This study investigated to what extent these cysts are resistant to physical and chemical stresses as applied in food industry cleaning and disinfection procedures. Moreover it was assessed whether certain intracystic meatborne bacterial pathogens are more stress-resistant than free-living bacterial monocultures and if intracystic passage and subsequent association with trophozoites induces cross-tolerance towards other stressors...

To inform regulatory decisions on the risk due to exposure to ambient air pollution, consistent and transparent communication of the scientific evidence is essential. The United States Environmental Protection Agency (U.S. EPA) develops the Integrated Science Assessment (ISA), which contains evaluations of the policy-relevant science on the effects of criteria air pollutants and conveys critical science judgments to inform decisions on the National Ambient Air Quality Standards. This article discusses the approach and causal framework used in the ISAs to evaluate and integrate various lines of scientific evidence and draw conclusions about the causal nature of air pollution-induced health effects...

AP1 transcription factors are important controllers of gene expression in the epidermis, and altered AP1 factor function can perturb keratinocyte proliferation and differentiation. However, our understanding of how AP1 signaling changes may underlie or exacerbate skin disease is limited. We have shown that inhibiting AP1 factor function in suprabasal adult epidermis leads to reduced filaggrin levels and to a phenotype that resembles the genetic disorder, ichthyosis vulgaris. We now show that inhibiting AP1 factor function during development in embryonic epidermis produces marked phenotypic changes including reduced filaggrin mRNA and protein levels, compromised barrier function, marked ultrastructural change and enhanced dehydration susceptibility that resembles the phenotype observed in the flaky tail mouse, a model for ichthyosis vulgaris...

The presence of minimal residual disease (MRD) is widely recognized as a powerful predictor of therapeutic outcome in acute myeloid leukemia (AML), but methods of measurement and quantification of MRD in AML are not yet standardized in clinical practice. There is an urgent, unmet need for robust and sensitive assays that can be readily adopted as real-time tools for disease monitoring. NPM1 frameshift mutations are an established MRD marker present in half of patients with cytogenetically normal AML. However, detection is complicated by the existence of hundreds of potential frameshift insertions, clonal heterogeneity, and absence of sequence information when the NPM1 mutation is identified using capillary electrophoresis...

Background.: Frailty is an age-related clinical syndrome of decreased resilience to stressors and is associated with numerous adverse outcomes. Although there is preponderance of literature on frailty in developed countries, limited investigations have been conducted in less developed regions including China-a country that has the world's largest aging population. We examined frailty prevalence in China by socio-demographics and geographic region, and investigated correlates of frailty...

Recurrence of bladder cancer can occur repeatedly in the same patient after treatment of the primary tumor. Models predicting the risk of a next recurrence may inform individualized decision-making on surveillance frequency. We aimed to assess the usefulness of extensions of the Cox proportional hazards model for repeated events in this context. We analyzed 531 Dutch patients with bladder cancer (1990-2012) with information on 7 pre-specified predictors at the time of diagnosing the primary and recurrent tumors...

Human activity is currently changing our environment rapidly, with predicted temperature increases of 1-5°C over the coming century and increased nitrogen and phosphorus inputs in aquatic ecosystems. In the shallow parts of these ecosystems, submerged aquatic plants enhance water clarity by resource competition with phytoplankton, provide habitat, and serve as a food source for other organisms. The carbon:nutrient stoichiometry of submerged aquatic plants can be affected by changes in both temperature and nutrient availability...

NRAS mutation in melanoma has been associated with aggressive tumor biology and poor prognosis. Although targeted therapy has been tested for NRAS mutated melanoma, response rates still appear much weaker, than in BRAF mutated melanoma. While plenty of cell lines exist, however, only few melanogenic cell lines retain their in vivo characteristics. In this work we present an intensively pigmented and well-characterized cell line derived from a highly aggressive NRAS mutated cutaneous melanoma, named MUG-Mel2...

The physiological effects of caesium (Cs) on living cells are poorly understood. Here, we examined the physiological role of Cs(+) on the activity of the potassium transporters in E. coli. In the absence of potassium (K(+)), Kup-mediated Cs(+) uptake partially supported cell growth, however, at a much lower rate than with sufficient K(+). In K(+)-limited medium (0.1 mM), the presence of Cs(+) (up to 25 mM) in the medium enhanced growth as much as control medium containing 1 mM K(+). This effect depended on the maintenance of basal levels of intracellular K(+) by other K(+) uptake transporters...

The malaria parasite Plasmodium falciparum invades human red blood cells via interactions between host and parasite surface proteins. By analyzing genome sequence data from human populations, including 1269 individuals from sub-Saharan Africa, we identify a diverse array of large copy number variants affecting the host invasion receptor genes GYPA and GYPB We find that a nearby association with severe malaria is explained by a complex structural rearrangement involving the loss of GYPB and gain of two GYPB-A hybrid genes, which encode a serologically distinct blood group antigen known as Dantu...

This study reports the first ever application of the trace element pollution index (TEPI) along a coastal, urban gradient using trace element concentrations (Ti, Mn, Co, Cu, As, Mo, Ag, Cd, Pb, Cr, Fe, Zn and Se) in the amphipod crustacean Talitrus saltator. Samples were collected from 10 sites in Galway Bay (Ireland) and concentrations of Pb showed the greatest spatial variation, likely due to the proximity of some sites to a former landfill and busy harbour. The TEPI used alongside the quartile method allowed for the assigning of sites to contamination level categories...

The aim of the present study was to examine the relationship between the use of key word signing (KWS) by support staff and by adults with intellectual disabilities (clients) who had experience with using KWS. Specifically, we explored whether these clients were more inclined to use KWS when support staff used KWS or imitated signs. One-to-one conversations between 24 clients and their support staff were filmed and transcribed. Partner turns were coded for communication mode (spoken or signed) and KWS response type (i...

BACKGROUND: People who have cancer increasingly seek second opinions. Yet, we know little about what motivates patients to seek them and how beneficial they are. Uncertainty-experienced by patients or communicated by physician and patient-may be crucial throughout the second opinion process. OBJECTIVE: This study sought to investigate (1) how uncertainty influences men with prostate cancer to seek second opinions and (2) how second opinions may affect these patients' sense of uncertainty and subsequent experiences with their care...

To determine the significance of TAR DNA binding protein 43 kDa (TDP-43) pathology in amyotrophic lateral sclerosis (ALS), we examined the whole brains and spinal cords of 57 patients (35 men; 22 women; mean age 63.3 years; 15 patients with c9orf72-associated ALS [c9ALS]). TDP-43 pathologic burden was determined relative to symptom onset site, disease duration, progression rate, cognitive status, and c9ALS status. There was a trend for greater TDP-43 pathologic burden in cognitively impaired patients (p = 0...

Purpose The purpose of the study was to describe outcomes that matter to teens with type 1 diabetes. Understanding outcomes that matter to teens could support successful interventions to improve diabetes self-management. Methods Fifty publicly available posts published in the "teen" sections of 2 major diabetes online forums between 2011 and 2013 were analyzed using qualitative research methods. From each post, content and descriptive data (eg, duration of diabetes and age) were collected. Two members of the research team independently used open coding techniques to identify outcomes (defined as impacts or consequences of type 1 diabetes) and organized them into themes and subthemes...
