Ureteral cancer in the retrocaval ureter is rare. We herein report a patient with this condition laparoscopically treated. A 69-year-old man was referred to us because of right ureteral cancer diagnosed during ureteroscopic surgery for a ureteral calculus. Histological diagnosis of the ureteroscopically biopsied material was non-invasive papillary urothelial carcinoma, low grade (G2). Computed tomography (CT) demonstrated a retrocaval ureter : a double J stent placed during ureteroscopy assisted the diagnosis...

Knee osteoarthritis (OA) affects 14 million individuals in the United States and over 250 million adults worldwide1,2 . OA of the lower extremities is associated with decreased quality of life and increased healthcare utilization3 . Recent estimates suggest that knee OA should not merely be considered a disease of aging - in the US alone more than half of those affected are under age 65, while close to 15% are under age 452 .

Objective: To develop an optical spectral transmission (OST) model to measure joint inflammation, and thus disease activity, as well as to evaluate (patho-)physiological findings that could lead to misclassification of inflammation. Methods: Forty-six RA patients were included in this cross-sectional study, where US scores, duplicate OST measurements and 28-joint DAS (DAS28) were acquired. With US as a reference standard, the diagnostic performance of OST in detecting inflammation at the joint level was evaluated using receiver operating characteristic (ROC) curve analyses...

Despite the fact that natural selection underlies both traits and interactions, evolutionary models often neglect that ecological interactions may, and in many cases do, influence the evolution of traits. Here, we explore the interdependence of ecological interactions and functional traits in the pollination associations of hawkmoths and flowering plants. Specifically, we develop an adaptation of the Ornstein-Uhlenbeck model of trait evolution that allows us to study the influence of plant corolla depth and observed hawkmoth-plant interactions on the evolution of hawkmoth proboscis length...

The Clinical Assessment Interview for Negative Symptoms (CAINS) was designed in accordance with the recent theory and research in social affective neuroscience and to address the psychometric and conceptual limitations of other instruments assessing negative symptoms. The present study aimed to provide a large-scale validation of the CAINS in China and examine its applicability and validity evidence across the schizophrenia spectrum. Using confirmatory factor analysis, our results replicated the original findings in the US development samples that the CAINS possesses a stable 2-factor structure, namely "motivation/pleasure" and "expression"...

Introduction: Despite effective treatments, relapse to smoking remains a vexing global health problem. One predictor of relapse is depressive symptoms. Medications such as varenicline reduce withdrawal-related symptoms of depression, reducing relapse. This study examined whether varenicline moderated the effect of depressive symptoms on relapse, and whether this varied by region of enrollment. Methods: Adult smokers (n=525; 37% male) with past or current, stable major depressive disorder recruited from US (n=255), and European (n=270) sites participated in a randomized, double-blind cessation treatment trial including 12 weeks of varenicline or placebo, with 40-week non-treatment follow-up...

Background: The herbicide alachlor has been widely used in US agriculture since its introduction in 1969. Experimental animal studies show that alachlor causes tumors in vivo; however, few epidemiologic studies have examined associations with human cancer risk. We evaluated alachlor use and cancer incidence in the Agricultural Health Study, updating an earlier analysis that suggested associations with lymphohematopoietic cancers with an additional 540 142 person-years of follow-up and 5113 cancer cases...

US midwifery education is provided through graduate education for the CNM/CM and didactic education with apprenticeship for the CPM. Clinical practice varies throughout the country depending on the credential held and current state legislation. A lack of clinical sites for midwifery education is a significant challenge to all programs and a barrier to meeting the national maternity care provider shortage.

Aspirin has positive effects on bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation. However, researchers did not give much thought to its effect on BMSCs adipogenic differentiation. Here, we analyzed the effect of aspirin on the BMSCs adipogenic differentiation. To detect whether the effect of aspirin on the adipogenic differentiation of BMSCs is associated with the disturbed epigenetic modification, the expression of histone deacetylases (HDACs), activity of HDACs and HAT, global histone H3 acetylation and H3k9 acetylation alterations were investigated...

REVIEW
Ilia N Karatsoreos
"Stress is complicated". A phrase uttered by many a stress researcher. This is true, from the vast array of stimuli considered "stressors" to the interactive and hormetic nature of the molecular, cellular, endocrine, and behavioral responses generated by such stressors. This commentary takes the position that stress researchers are poised to make even bigger contributions if they begin to shift from investigating the myriad effects of stress on brain and body, and to refocus a larger part of our efforts on more in-depth investigations of common themes in stress biology, with the goal of uncovering potential "universal principles" of stress that may help us better interpret the findings at higher levels of analysis, and provide a structured approach to help breach the next frontiers of stress research...

The definition of a suitable mesh to simulate blood flow in the human carotid bifurcation has been investigated. In this research, a novel mesh generation method is proposed: hexahedral cells at the centre of the vessel and a fine grid of tetrahedral cells near the artery wall, in order to correctly simulate the large blood velocity gradients associated with specific locations. The selected numerical examples to show the pertinence of the novel generation method are supported by carotid ultrasound (US) image data of a patient-specific case...

Objectives Pacific Islanders are disproportionately burdened by poorer perinatal health outcomes with higher rates of pre-term births, low birth weight babies, infant mortality, and inadequate or no prenatal care. The aim of this study is to examine Marshallese mothers' beliefs, perceptions, and experiences of prenatal care and to identify potential barriers. Methods Three focus groups were conducted with Marshallese mothers, who were 18 years or older, and living in Arkansas. Focus groups focused on mothers' beliefs, perceptions, and experiences of prenatal care...

PURPOSE OF REVIEW: Increasing hepatitis C virus (HCV) cases over the past decade have raised concerns about subsequent increased cases in infants due to mother to child transmission (MTCT). Many are reminded of the early days of HIV and the rationale for using antiretroviral agents during pregnancy. RECENT FINDINGS: Direct-acting antivirals (DAAs) that are highly potent, all-oral, short-duration regimens that cure HCV have led many to consider what it would entail to use DAAs for pregnant women...

We explain the anomaly of election results between large cities and rural areas in terms of urban scaling in the 1948-2016 US elections and in the 2016 EU referendum of the UK. The scaling curves are all universal and depend on a single parameter only, and one of the parties always shows superlinear scaling and drives the process, while the sublinear exponent of the other party is merely the consequence of probability conservation. Based on the recently developed model of urban scaling, we give a microscopic model of voter behavior in which we replace diversity characterizing humans in creative aspects with social diversity and tolerance...

Whereas the topic of the 'cultural sensitivity' of healthcare systems has been addressed extensively in the US and the UK, literature on the subject in most European countries, specifically looking at the situation of Roma, is still scarce. Drawing on qualitative research conducted mainly in the city of Barcelona under the communicative approach with Roma subjects who have stable socioeconomic positions and higher cultural capitals (end-users, professionals of the healthcare system, and key informants of a regional policy oriented to the improvement of Roma living conditions), the present study aims to fill this gap...

The study of aliphatic compounds adsorption on activated carbon can be carried out from the energetic change involved in the interaction; the energy values can be determined from isotherms or by the immersion enthalpy. Vapor phase adsorption isotherms of hexane at 263 K on five activated carbons with different content of oxygenated groups and the immersion enthalpy of the activated carbons in hexane and water were determined in order to characterize the interactions in the solid-liquid system, and for calculating the hydrophobic factor of the activated carbons...
