    Spatial Learning Responses to Lipopolysaccharide in Adult and Aged Rats.
    Biol Res Nurs 2017 Jan 1:1099800417726875. Epub 2017 Jan 1.
    2 School of Nursing, University of Michigan, Ann Arbor, MI, USA.
    Sickness behaviors, adaptive responses to infections, include lethargy, depression, reduced eating and grooming, and concentration problems resulting from interactions between the immune and neuroendocrine systems. Detecting these responses is especially critical in the elderly, as the infections that cause them can lead to cognitive impairment. While deficits in spatial learning, a hippocampal-dependent form of learning, are part of the sickness response, directional heading errors (DHEs; an indicator of spatial-learning deficits) and their time trajectories need further examination.

    Plasma and Urinary Oxytocin Trajectories in Extremely Premature Infants During NICU Hospitalization.
    Biol Res Nurs 2017 Oct 12;19(5):549-558. Epub 2017 Jul 12.
    2 The Ohio State University College of Nursing, Columbus, OH, USA.
    Extremely premature infants are at great risk for poor neurodevelopmental outcomes, in part because neurologic structures designed to mature in the womb must now do so in the extrauterine environment. Reliable biomarkers of neurodevelopment are especially critical in this population, as behavioral measures can be unreliable due to immaturity of the premature infant nervous system. Oxytocin (OT) has the potential to be a marker of neurobiological processes that offer infant neuroprotection. Read More

    The Relation Between Physical Activity and Cognitive Change in Older Latinos.
    Biol Res Nurs 2017 Oct 29;19(5):538-548. Epub 2017 Jun 29.
    2 Rush Alzheimer's Disease Center, Rush University Medical Center, Chicago, IL, USA.
    Cognitive impairment in older Latinos is of concern due to the rapid growth of this population and their increased risk for dementia due to chronic disease. Evidence, primarily from studies of non-Latino Whites, suggests that physical activity (PA) may reduce cognitive decline. Few longitudinal studies have included older Latinos, objective measures of PA, or neurocognitive tests that assess domains of cognition. Read More

    Measuring Light at Night and Melatonin Levels in Shift Workers: A Review of the Literature.
    Biol Res Nurs 2017 Jul;19(4):365-374
    1 Lighting Research Center, Rensselaer Polytechnic Institute, Troy, NY, USA.
    Shift work, especially that involving rotating and night shifts, is associated with an increased risk of diseases, including cancer. Attempts to explain the association between shift work and cancer in particular have focused on the processes of melatonin production and suppression. One hypothesis postulates that exposure to light at night (LAN) suppresses melatonin, whose production is known to slow the development of cancerous cells, while another proposes that circadian disruption associated with shift work, and not just LAN, increases health risks.

    Measuring Stress in Young Children Using Hair Cortisol: The State of the Science.
    Biol Res Nurs 2017 Oct 15;19(5):499-510. Epub 2017 Jun 15.
    1 College of Nursing, The Ohio State University, Columbus, OH, USA.
    Extensive literature suggests that adverse experiences in early childhood may deleteriously impact later health. These effects are thought to be related to the impact of persistent or chronic stress on various biological processes, mediated by dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, and ultimately irregularities in cortisol levels. Ameliorating persistent stress in young children requires accurately measuring the chronicity of physiologic stress, which is difficult in young children because of unreliable self-report and the burden and inaccuracy associated with using invasive acute-stress biomeasures.

    IL-10 Gene Polymorphisms and Self-Medication With Over-the-Counter Nonsteroidal Anti-Inflammatory Drugs.
    Biol Res Nurs 2017 May 30;19(3):329-338. Epub 2017 Jan 30.
    1 School of Nursing, University of Connecticut, Storrs, CT, USA.
    Background: Genetic influences on self-medication with over-the-counter (OTC) drugs merit investigation. For example, patients frequently use OTC nonsteroidal anti-inflammatory drugs (NSAIDs) to treat inflammation, but the inflammatory response is also affected by endogenous cytokines whose production varies across polymorphisms of their encoding genes. In the case of interleukin 10 (IL-10), literature suggests that a single nucleotide polymorphism (SNP) in the promoter region of the cytokine's gene (-1082 A > G [rs1800896]) influences production with higher levels associated with G variant alleles.

    Precision medicine refers to the practice of determining a patient's unique genetic, biomarker, and other characteristics for the purpose of improving his or her clinical outcomes. Not all patients with the same clinical diagnosis respond equally to identical treatment regimens. By examining patients at the molecular level, health-care providers will be better able to apply the most effective therapies that each individual requires. Read More

    Chronic stress may accelerate cellular aging. Telomeres, protective "caps" at the end of chromosomes, modulate cellular aging and may be good biomarkers for the effects of chronic stress, including that associated with acculturation. The purpose of this analysis was to examine telomere length (TL) in acculturating Hispanic Mexican American women and to determine the associations among TL, acculturation, and psychological factors.

    Introduction: Treatment of venous thromboembolism (VTE) is classically based on oral vitamin K antagonists (VKAs). Due to the disadvantages and side effects of these drugs, monitoring the quality of anticoagulation by assessing time within therapeutic range (TTR) is recommended. Variables altering the TTR in patients with VTE are yet to be determined. Read More

    Patients in intensive care units (ICUs) often experience stress and anxiety. Although stress and anxiety can be pharmacologically attenuated, some drugs cause adverse side effects such as bradycardia, immobility, and delirium. There is thus a need for an alternative treatment with no substantial adverse effects. Read More
