Pulmonary hypertension (PH) complicating bronchopulmonary dysplasia (BPD) worsens clinical outcomes in former preterm infants. Increased serotonin (5-hydroxytryptamine, 5-HT) signaling plays a prominent role in PH pathogenesis and progression in adults. We hypothesized that increased 5-HT signaling contributes to the pathogenesis of neonatal PH complicating BPD and neonatal lung injury. Thus, we interrogated 5-HT signaling in neonatal mice exposed to bleomycin, previously demonstrated to induce PH and alveolar simplification...

We aimed to determine whether aflatoxin dietary exposure plays a role in the high incidence of hepatocellular carcinoma (HCC) observed among Hispanics in South Texas. We measured TP53R249S somatic mutation, hallmark of aflatoxin etiology in HCC, using droplet digital PCR and RFLP. TP53R249S mutation was detected in 3 of 41 HCC tumors from Hispanics in South Texas (7.3%). We also measured TP53R249S mutation in plasma cell-free DNA (cfDNA) from 218 HCC patients and 96 Hispanic subjects with advanced fibrosis or cirrhosis, from South Texas...

In order to develop a catalog of regulatory sites in two major model organisms, Drosophilia melanogaster and Caenorhabditis elegans, the modERN consortium has systematically assayed the binding sites of transcription factors (TFs). Combined with data produced by our predecessor, modENCODE, we now have data for 262 TFs identifying 1.23M sites in the fly genome and 217 TFs identifying 0.67M sites in the worm genome. Because sites from different TFs are often overlapping and tightly clustered, they fall into 91,011 and 59,150 regions in the fly and worm, respectively, and these binding sites span as little as 8...

The presence of organic matter (OM) has a profound impact on uranium (U) redox cycling, either limiting or promoting the mobility of U via binding, reduction, or complexation. To understand the interactions between OM and U, we characterised U oxidation state and speciation in nine OM-rich sediment cores (18 samples), plus a lignite sample from the Mulga Rock polymetallic deposit in Western Australia. Uranium was unevenly dispersed within the analysed samples with 84% of the total U occurring in samples containing >21 wt % OM...

BACKGROUND: Delirium affects up to 80% of critically ill patients; however, many cases of delirium go unrecognized because of inaccurate assessments. The effectiveness of interventions to improve assessment accuracy among the general population has been established, but assessments among neuroscience patients are uniquely complicated due to the presence of structural neurologic changes. OBJECTIVES: The purposes of this quality improvement project were to improve the accuracy of nurse's delirium assessments among neuroscience patients and to determine the comparative effectiveness of the intervention between medical and neuroscience patients...

Service learning is an educational methodology that facilitates transformation of students' knowledge, attitudes and attitudes around holistic care through work with community organizations. To implement academically, defensible service learning requires faculty endorsement, consideration of course credit, an enthusiastic champion able to negotiate agreements with organizations, organizations' identification of their own projects so they are willing to both fund and supervise them, curricular underpinning that imparts the project skills necessary for success, embedding at a time when students' clinical identity is being formed, small packets of curriculum elements delivered "just in time" as students engage with their project, flexible online platform/s, assessment that is organically related to the project, providing cross cultural up-skilling, and focused on the students' responsibility for their own product...

Fetal growth restriction (FGR) affects up to 5% of pregnancies and is associated with significant perinatal complications. Maternal deficiency of vitamin D, a secosteroid hormone, is common in FGR-affected pregnancies. We recently demonstrated that decreased expression of the vitamin D receptor (VDR) in idiopathic FGR placentae could impair trophoblast growth. As strict regulation of cell-cycle genes in trophoblast cells is critical for optimal feto-placental growth, we hypothesised that pathologically decreased placental VDR contributes to aberrant regulation of cell-cycle genes...

As more people live longer, age-related neurodegenerative diseases are an increasingly important societal health issue. Treatments targeting specific pathologies such as amyloid beta in Alzheimer's disease (AD) have not led to effective treatments, and there is increasing evidence of a disconnect between traditional pathology and cognitive abilities with advancing age, indicative of individual variation in resilience to pathology. Here, we generated a comprehensive neuropathological, molecular, and transcriptomic characterization of hippocampus and two regions cortex in 107 aged donors (median = 90) from the Adult Changes in Thought (ACT) study as a freely-available resource (http://aging...

INTRODUCTION: It was observed that women with aneurysmal subarachnoid hemorrhage (aSAH) tended to have earlier menses than a typical 21- to 28-day cycle. The goal was to determine whether there is an association between aSAH and early onset of menses. METHODS: All cases of aSAH in women aged 18 to 55 years who were admitted to our facility's neuroscience intensive care unit from June 1, 2011, to June 30, 2012, were reviewed. The electronic healthcare record for each of these patients was examined for documentation of menses onset, computed tomography of the head, brain aneurysm characteristics, modified Fisher score and Glasgow Coma Scale on admission, presence/absence of vasospasm, medical/surgical history, and use of medications that affect the menstrual cycle...

BACKGROUND: Recent analyses of trait-disorder overlap suggest that psychiatric dimensions may relate to distinct sets of genes that exert maximum influence during different periods of development. This includes analyses of social communication difficulties that share, depending on their developmental stage, stronger genetic links with either autism spectrum disorder or schizophrenia. We developed a multivariate analysis framework in unrelated individuals to model directly the developmental profile of genetic influences contributing to complex traits, such as social communication difficulties, during an approximately 10-year period spanning childhood and adolescence...

BACKGROUND: The gold standards for assessing ambulation are the Expanded Disability Status Scale (EDSS) and the Timed 25-Foot Walk (T25FW) test. In relation with these measures, we assessed the reliability and validity of four clinical gait measures: the Timed Up and Go (TUG) test, the Dynamic Gait Index (DGI), the 2-Minute Walk Test (2MWT), and the 6-Minute Walk Test (6MWT). Patient self-report of gait was also assessed using the 12-item Multiple Sclerosis Walking Scale (MSWS-12). METHODS: Individuals 20 years or older with a diagnosis of multiple sclerosis (MS) and an EDSS score of 2...

Background: The risk of infection with Mycobacterium tuberculosis among healthcare workers (HCWs) is estimated to be higher than the general population. However, HCW acceptance and compliance with available latent tuberculosis infection (LTBI) treatment regimens has been problematic. Recently, regimens have become available that might improve HCW acceptance and compliance with LTBI treatment. Methods: A retrospective single-center review of Employee Health &Wellness Services records of all HCWs diagnosed with LTBI was conducted...

Early-life environmental factors can influence later-life susceptibility to cancer. Recent evidence suggests that metabolic pathways may mediate this type of latency effect. Previously, we reported that short-term exposure to dichloroacetic acid (DCA) increased liver cancer in mice 84 weeks after exposure was stopped. Here, we evaluated time course dynamics for key events related to this effect. This study followed a stop-exposure design in which 28-day-old male B6C3F1 mice were given the following treatments in drinking water for up to 93 weeks: deionized water (dH2O, control); 3...
