We analyzed chromatin dynamics and transcriptional activity of human embryonic stem cell (hESC)-derived cardiac progenitor cells (CPCs) and KDR(+)/CD34(+) endothelial cells generated from different mesodermal origins. Using an unbiased algorithm to hierarchically rank genes modulated at the level of chromatin and transcription, we identified candidate regulators of mesodermal lineage determination. HOPX, a non-DNA-binding homeodomain protein, was identified as a candidate regulator of blood-forming endothelial cells...

OBJECTIVE: Research has demonstrated that a lack of social support is related to suicide risk. This study exams perceived burdensomeness and thwarted belongingness, of the Interpersonal Theory of Suicide, as mechanisms of the social support-suicide relationship in college students. METHOD: The study consisted of 207 students from a Midwestern university. Data were collected from 2007-2008. Two multiple mediation analyses were conducted to examine whether perceived burdensomeness and thwarted belongingness mediated the relationship between indices of social support and suicide ideation...

OBJECTIVE: The current Juvenile Idiopathic Arthritis (JIA) Core Set was developed in 1997 to identify the outcome measures to be used in JIA clinical trials using statistical and consensus-based techniques, but without patient involvement. The importance of patient/parent input into the research process has increasingly been recognized over the years. An Outcome Measures in Rheumatology (OMERACT) JIA Core Set Working Group was formed to determine whether the outcome domains of the current core set are relevant to those involved or whether the core set domains should be revised...

Chemotherapy is widely used to treat patients with systemic cancer. The efficacy of cancer therapies is frequently undermined by adverse side effects that have a negative impact on the quality of life of cancer survivors. Cancer patients who receive chemotherapy often experience chemotherapy-induced cognitive impairment across a variety of domains including memory, learning, and attention. In the current study, the impact of paclitaxel, a taxane derived chemotherapeutic agent, on episodic memory, prior learning, new learning, and reversal learning were evaluated in rats...

BACKGROUND: Though direct acting antivirals (DAAs) promise high cure rates, many providers and payers remain concerned about successful treatment for people who use drugs (PWUD), even among those engaged in opioid agonist treatment (OAT). The efficacy of DAAs among PWUD in real-world settings is unclear. METHODS: We conducted a cohort study of patients initiating HCV treatment between January 2014 and August 2015 (n=89) at a primary care clinic in the Bronx, NY...

This study introduces a standardized protocol for conducting linear measurements of postcranial skeletal elements using three-dimensional (3D) models constructed from post-mortem computed tomography (PMCT) scans. Using femoral DICOM datasets, reference planes were generated and plane-to-plane measurements were conducted on 3D surface rendered models. Bicondylar length, epicondylar breadth, anterior-posterior (AP) diameter, medial-lateral (ML) diameter and cortical area at the midshaft were measured by four observers to test the measurement error variance and observer agreement of the protocol (n=6)...

Enterolignans, products of gut bacterial metabolism of plant lignans, have been associated with reduced risk of chronic diseases, but their association with other plasma metabolites is unknown. We examined plasma metabolite profiles according to urinary enterolignan excretion in a cross-sectional analysis using data from a randomized crossover, controlled feeding study. Eighty healthy adult males and females completed two 28-day feeding periods differing by glycemic load, refined carbohydrate, and fiber content...

Mutations activating KRAS underlie many forms of cancer, but are refractory to therapeutic targeting. Here, we develop Poloppin, an inhibitor of protein-protein interactions via the Polo-box domain (PBD) of the mitotic Polo-like kinases (PLKs), in monotherapeutic and combination strategies to target mutant KRAS. Poloppin engages its targets in biochemical and cellular assays, triggering mitotic arrest with defective chromosome congression. Poloppin kills cells expressing mutant KRAS, selectively enhancing death in mitosis...

BACKGROUND: Neoadjuvant treatment is standard for locally advanced esophageal cancer. However, whether the addition of radiation to neoadjuvant regimen improves survival remains unclear. The aim of this study was to compare survival in locally advanced esophageal cancer treated with neoadjuvant chemotherapy versus chemoradiation. MATERIALS AND METHODS: A prospectively maintained database of esophagectomies (1999-2012) was analyzed. We identified 297 patients with locally advanced esophageal cancer that underwent either neoadjuvant chemotherapy (n = 231) or chemoradiation (n = 66) followed by esophagectomy...

OBJECTIVE: Cochlear implant research and product development over the past 40 years have been heavily focused on speech comprehension with little emphasis on music listening and enjoyment. The relatively little understanding of how music sounds in a cochlear implant user stands in stark contrast to the overall degree of importance the public places on music and quality of life. The purpose of this article is to describe what music sounds like to cochlear implant users, using a combination of existing research studies and listener descriptions...

Primary central nervous system lymphoma (PCNSL) risk is greatly increased in immunosuppressed HIV-infected people. Using data from the United States transplant registry linked with 17 cancer registries (1987-2014), we studied PCNSL and systemic non-Hodgkin lymphoma (NHL) in 288,029 solid organ transplant recipients. Transplant recipients had elevated incidence for PCNSL compared with the general population (standardized incidence ratio=65.1; N=168), and this elevation was stronger than for systemic NHL (standardized incidence ratio=11...

BACKGROUND: Monitoring cancer risk among HIV-infected people in the modern antiretroviral therapy (ART) era is essential given their elevated risk for many cancers and prolonged survival with immunosuppression, ART exposure, and ageing. We aimed to examine cancer risk in HIV-infected people in the USA as compared with that in the general population. METHODS: We did a registry-linkage study with data from population-based HIV and cancer registries in the USA (the HIV/AIDS Cancer Match Study)...

OBJECTIVES: To measure the urodynamic effects of electrical co-stimulation of two individual sites in the proximal and distal urethra in persons with spinal cord injury (SCI). This work was motivated by preclinical findings that selective co-stimulation of the cranial urethral sensory nerve and the dorsal genital nerve, which innervate the proximal and distal portions of the urethra, respectively, increased reflex bladder activation and voiding efficiency. METHODS: Electrical co-stimulation of urethral afferents was conducted in persons with chronic SCI during urodynamics...

OBJECTIVES: Para-aortic lymph node involvement in women with endometrial carcinoma (EC) is a poor prognostic factor. Many studies have included women with stage IIIC2 in cohorts of patients with advanced stage disease. The aim of this study was to analyze survival outcomes and patterns of failure in women with solely stage IIIC2 EC. METHODS: We identified women with FIGO stage IIIC2 EC who underwent surgical staging at our institution. In addition to descriptive analyses of patient demographics, tumor characteristics, and adjuvant treatment received, univariate log-rank analyses and Cox regression multivariate analyses (MVA) were performed to identify predictors of recurrence-free (RFS), disease-specific (DSS) and overall survival (OS)...

BACKGROUND: The care needs of women with gynecological cancer are complex and change over the course of their cancer journey. Specialist nurses are well positioned to play a role in meeting the needs of women with gynecological cancer although their role and scope of practice have not been well defined. As patients are a key stakeholder, understanding their experience of care is an important step in better defining the role and scope of practice of specialist nurses in gynecological oncology in Australia and New Zealand...

Exposure to nitrogen dioxide (NO2), a byproduct of combustion, is associated with poor asthma control in children. We sought to determine whether gas-fueled kitchen appliance use is associated with 24-h indoor NO2 concentrations and whether these concentrations are associated with asthma morbidity in children. Children aged 5-12 years old with asthma were eligible. Mean 24-h NO2 concentration was measured in the kitchen over a four-day sampling period and gas stove use was captured in time activity diaries...

OBJECTIVES: The literature demonstrates that 'aggressive' head-and-neck basal cell carcinomas (HN-BCC) have a higher than expected relapse rate with unfavorable outcomes. We report outcomes following definitive (dRT) or post-operative radiotherapy (PORT) for these tumors. METHODS: We reviewed all HN-BCC patients with 'aggressive' features (primary lesions diameter >10mm, >2 recurrences, or extra-cutaneous extension), treated with megavoltage dRT or PORT between 1998 and 2013...
