    A decrease in intact parathyroid hormone (iPTH) levels is associated with higher mortality in prevalent hemodialysis patients.
    PLoS One 2017 24;12(3):e0173831. Epub 2017 Mar 24.
    Servicio de Nefrología, Fundación Jiménez Díaz, Madrid, España.
    Background: The mortality of dialysis patients is 10- to 100-fold higher than in the general population. Baseline serum PTH levels, and more recently, changes in serum PTH levels (ΔPTH) over time, have been associated to mortality in dialysis patients.

    Methods: We explored the relationship between ΔPTH over 1 year with mortality over the next year in a prospective cohort of 115 prevalent hemodialysis patients from a single center that had median baseline iPTH levels within guideline recommendations. Read More

    Genomic Loads and Genotypes of Respiratory Syncytial Virus: Viral Factors during Lower Respiratory Tract Infection in Chilean Hospitalized Infants.
    Int J Mol Sci 2017 Mar 21;18(3). Epub 2017 Mar 21.
    Department of Pediatrics and Pediatric Surgery, Hospital Roberto del Río, Facultad de Medicina, Universidad de Chile, Profesor Zañartu 1085, Independencia, 8380418 Santiago, Chile.
    The clinical impact of viral factors (types and viral loads) during respiratory syncytial virus (RSV) infection is still controversial, especially regarding newly described genotypes. In this study, infants with RSV bronchiolitis were recruited to describe the association of these viral factors with severity of infection. RSV antigenic types, genotypes, and viral loads were determined from hospitalized patients at Hospital Roberto del Río, Santiago, Chile. Read More

    The Influence of Exercise on Cognitive Function in Older Hispanic/Latino Adults: Results From the "¡Caminemos!" Study.
    Gerontologist 2017 Nov;57(6):1072-1083
    Department of Medicine, David Geffen School of Medicine at UCLA and VA Greater Los Angeles Geriatric Research Education and Clinical Center, Los Angeles, California.
    Purpose Of The Study: We examined the prospective effect of an evidence-based exercise intervention (¡Caminemos!) on cognitive function among older Hispanic/Latino adults and the potential synergistic effects (if any) of an attribution-retraining intervention given to a random sample to counter negative ascriptions of the aging process.

    Design And Methods: We analyzed baseline and follow-up (1- and 2-year) data collected from Hispanics/Latinos ≥60 years (N = 571) who participated in ¡Caminemos! across 27 senior centers. All participants were randomly assigned to either (a) the treatment group-a 1-hr attribution-retraining session plus a 1-hr exercise class or (b) the control group-health education plus a 1-hr exercise class.

    The relationship between nasopharyngeal CCL5 and microbiota on disease severity among infants with bronchiolitis.
    Allergy 2017 Nov 12;72(11):1796-1800. Epub 2017 Apr 12.
    Department of Emergency Medicine, Harvard Medical School, Massachusetts General Hospital, Boston, MA, USA.
    Emerging evidence suggests that the airway microbiota plays an important role in viral bronchiolitis pathobiology. However, little is known about the combined role of airway microbiota and CCL5 in infants with bronchiolitis. In this multicenter prospective cohort study of 1005 infants (age <1 year) hospitalized for bronchiolitis during 2011-2014, we observed statistically significant interactions between nasopharyngeal airway CCL5 levels and microbiota profiles with regard to the risk of both intensive care use (P =.

    The interdependencies of viral load, the innate immune response, and clinical outcome in children presenting to the emergency department with respiratory syncytial virus-associated bronchiolitis.

    Department of Molecular Virology and Microbiology, Baylor College of Medicine, Houston, Texas, United States of America.
    Respiratory syncytial virus (RSV) causes significant infant morbidity and mortality. For decades severe RSV-induced disease was thought to result from an uncontrolled host response to viral replication, but recent work suggests that a strong innate immune response early in infection is protective. To shed light on host-virus interactions and the viral determinants of disease, copy numbers of five RSV genes (NS1, NS2, N, G, F) were measured by quantitative real-time polymerase chain reaction (qPCR) in nasal wash samples from children with RSV-associated bronchiolitis.

    Very high MHC Class IIB diversity without spatial differentiation in the mediterranean population of greater Flamingos.
    BMC Evol Biol 2017 02 20;17(1):56. Epub 2017 Feb 20.
    Université de Bourgogne, Equipe Ecologie Evolutive, UMR CNRS 6282 Biogéosciences, 6 bd. Gabriel, 21000, Dijon, France.
    Background: Selective pressure from pathogens is thought to shape the allelic diversity of major histocompatibility complex (MHC) genes in vertebrates. In particular, both local adaptation to pathogens and gene flow are thought to explain a large part of the intraspecific variation observed in MHC allelic diversity. To date, however, evidence that adaptation to locally prevalent pathogens maintains MHC variation is limited to species with limited dispersal and, hence, reduced gene flow. Read More
