Reliability of Total Bilirubin Measurements in Whole Blood from Preterm Neonates Using a Blood Gas Analyzer.

BACKGROUND Blood gas analyses are usually required more frequently in preterm neonates than in term neonates. If total bilirubin (TB) levels in whole blood measured using a blood gas analyzer are reliable, blood sampling for total serum bilirubin (TSB) levels alone can be reduced in preterm neonates. We investigated the reliability of measuring TB levels in whole blood from preterm neonates using the latest generation blood gas analyzer. METHODS TB measured on an ABL90 FLEX blood gas analyzer and TSB analyzed in the hospital laboratory were simultaneously analyzed. TB and TSB levels (300 data sets in 85 preterm neonates) were compared using linear regression and Bland-Altman difference plots. RESULTS Concordance correlation coefficient analysis showed a strong relationship between TB and TSB levels (a CCC value of 0.94) with a Pearson's coefficient of 0.97 and a bias correction of 0.97. Bland-Altman difference p lots demonstrated that, on average, TB tended to underestimate the TSB, with a mean (95% confidence interval) bias of -0.7 (-0.6 to -0.8) mg/dL. CONCLUSIONS Whole blood TB levels measured using an ABL90 FLEX are reliable and can lead to a reduction in blood sampling for TSB in preterm neonates.
Increased Killing of Staphylococci and Streptococci by Daptomycin Compared with Cefazolin and Vancomycin in an In Vitro Peritoneal Dialysate Model

ABSTRACT Peritoneal dialysate fluid (PDF) is a bacteriostatic medium that compromises the antibacterial activity of cell wall-active agents. By use of an in vitro static model, methicillin-resistant Staphylococcus aureus (MRSA), methicillin-susceptible S. aureus (MSSA), methicillin-susceptible Staphylococcus epidermidis (MSSE), and Streptococcus sanguis were exposed to daptomycin at concentrations of 10, 30, and 100 mg/liter, cefazolin at 125 mg/liter, and vancomycin at 25 mg/liter in cation-adjusted Mueller-Hinton Broth or Todd Hewitt Broth (for S. sanguis) and PDF at pHs of 5.5 and 7.4. The pH had no effect on antibacterial activity. Neither cefazolin nor vancomycin produced a bactericidal or a bacteriostatic effect versus MRSA, MSSA, MSSE, or S. sanguis in PDF, while all concentrations of daptomycin were bactericidal against all organisms in PDF. Daptomycin did not exhibit concentration-dependent activity in PDF. Daptomycin appears to be a promising agent for use in peritoneal dialysis-associated peritonitis, producing bacterial kill to a greater extent and at a higher rate than cefazolin or vancomycin in PDF.
Oral Clearance and Acid Production of Dairy Products during Interaction with Sweet Foods

Oral clearance and acid production were observed in 30 volunteers following the ingestion of sharp cheddar cheese (CC) and in 9 volunteers following the ingestion of milk chocolate (MC) and low-fat yogurt, and then when MC was eaten immediately after CC (CC/MC) and when CC was eaten following MC (MC/CC). After each test food or food combination had been ingested the volunteers were monitored at five different tooth sites. At each site, using an absorbent paper point, 4 oral fluid samples were collected at 30 min intervals. The five paper points from each sampling occasion were pooled, extracted with 1 ml of water and analyzed qualitatively and quantitatively for both carbohydrates and organic acids using HPLC. Data obtained for each food was averaged and subjected to statistical evaluation. With the CC, glucose clearance was prolonged, due to intermediate lactose degradation into galactose and glucose. The quantity of lactic acid produced during the four intervals was monitored for each of the test foods and their combinations. Results: CC, MC, CC/MC, MC/CC 30 min after ingestion: 1.64, 3.47, 4.68, 2.97; after 60 min: 1.30, 1.24, 1.28, 1.43; after 90 min: 1.58, 1.02, 0.76, 0.43; after 120 min: 1.27, 0.90, 0.70, 0.42 mmol lactic acid/l oral fluid, respectively. The average total amount of lactic acid obtained during the two hour test period was (highest) CC/MC > MC > CC > MC/CC (lowest). The lowest amount of intra-oral lactic acid was observed (Student’s t test, p < 0.05) when cheddar cheese (CC) was eaten immediately after the milk chocolate (MC). Clinical Significance: Consumption of cheese (cheddar), immediately after a sweet meal, significantly reduces (approx. 30%) the amount of lactic acid produced in the oral cavity, when compared to the amount of acid obtained from the sweet food alone.
High-density lipoproteins inhibit cytokine-induced expression of endothelial cell adhesion molecules.

While an elevated plasma concentration of HDLs is protective against the development of atherosclerosis and ensuing coronary heart disease (CHD), the mechanism of this protection is unknown. One early cellular event in atherogenesis is the adhesion of mononuclear leukocytes to the endothelium. This event is mediated principally by vascular cell adhesion molecule-1 (VCAM-1) but also involves other molecules, such as intercellular adhesion molecule-1 (ICAM-1) and E-selectin. We have investigated the effect of isolated plasma HDLs and reconstituted HDLs on the expression of these molecules by endothelial cells. We show that physiological concentrations of HDLs inhibit tumor necrosis factor-alpha (TNF-alpha) or interleukin-1 (IL-1) induction of these leukocyte adhesion molecules in a concentration-dependent manner. Steady state mRNA levels of TNF-alpha-induced VCAM-1 and E-selectin are significantly reduced by physiological concentrations of HDLs. An an HDL concentration of 1 mg/mL apolipoprotein A-I, the protein expressions of VCAM-1, ICAM-1, and E-selectin were inhibited by 89.6 +/- 0.4% (mean +/-SD, n=4), 64.8 +/- 1.0%, and 79.2 +/- 0.4%, respectively. In contrast, HDLs have no effect on the expression of platelet endothelial cell adhesion molecule (PECAM) or on the expression of the p55 and p75 subunits of the TNF-alpha receptor. HDLs were effective when added from 16 hours before to 5 minutes after cytokine stimulation. HDLs had no effect on TNF-alpha-induced expression of ICAM-1 by human foreskin fibroblasts, suggesting that the effect is cell-type restricted. (ABSTRACT TRUNCATED AT 250 WORDS)
Differential Effects of Protein Synthesis Inhibition on the Activity-Dependent Expression of BDNF Transcripts: Evidence for Immediate-Early Gene Responses from Specific Promoters

In the adult rat forebrain, brain-derived neurotrophic factor (BDNF) expression is very rapidly induced by neuronal activity, suggesting that this might occur without intervening protein synthesis. The rat BDNF gene has four differentially regulated promoter regions; each gives rise to an mRNA containing a unique 5′ exon (I–IV) and a common 3′ exon (V) that codes for mature BDNF protein. The present study used exon-specific in situ hybridization and both in vivo andin vitro preparations to determine whether activity induces BDNF as an “immediate-early gene” (IEG) from specific promoter regions and to compare the regulation of BDNF and nerve growth factor (NGF). In cultured hippocampal slices, kainic acid markedly increased pan-BDNF (exon V) and NGF mRNA content; cycloheximide attenuated the effect of kainic acid on both. In vivostimulation of a paroxysmal afterdischarge increased both pan-BDNF and NGF mRNA levels in the dentate gyrus granule cells; pretreatment with anisomycin modestly attenuated the paroxysmal afterdischarge-induced increase of both transcripts. To determine whether partial drug effects on BDNF expression reflect the differential regulation of transcript species, levels of mRNAs containing exons I–IV were evaluated. A single afterdischarge increased exon I–IV-containing mRNA levels; anisomycin significantly attenuated the increase in exon I- and II-containing mRNAs but had no effect on the increase in exon III- and IV-containing mRNAs. These data show that for mature forebrain neurons, activity induces the expression of BDNF exon III- and IV-containing transcripts as IEG responses.
Complete paternal uniparental isodisomy of chromosome 1 resulting in Herlitz junctional epidermolysis bullosa

Herlitz junctional epidermolysis bullosa (JEB) is an autosomal recessive mechanobullous disorder that results from loss‐of‐function mutations in the genes encoding the basement membrane component, laminin 5. Typically, there are frameshift, splice site or nonsense mutations on both alleles of either the LAMA3, LAMB3 or LAMC2 genes, with affected individuals inheriting one mutated allele from each parent. In this report, we describe a patient with Herlitz JEB in whom DNA analysis revealed homozygosity for the recurrent nonsense mutation R635X in LAMB3, located on chromosome 1q32.2. However, screening of parental DNA showed that although the patient's father was a heterozygous carrier of this mutation, the mother's DNA showed only wild‐type sequence. Subsequent genotype analysis using 13 microsatellite markers spanning chromosome 1 revealed that the affected child was homozygous for the entire series of markers tested and that all of the alleles originated from the father. These results indicate that the Herlitz JEB phenotype in this patient is due to complete paternal isodisomy of chromosome 1 and reduction to homozygosity of the mutant LAMB3 gene locus. This is the fourth case of uniparental disomy to be described in Herlitz JEB, but it represents the first example of complete paternal isodisomy for chromosome 1 with a pathogenic mutation in the LAMB3 gene. These findings have important implications for mutation screening in JEB and for genetic counselling.
Choosing a diagnostic cut-off for cannabis dependence.

AIM While cannabis dependence has been increasingly recognized, there is little research on the measurement issues involved in operationalizing the dependence syndrome for this drug. This paper aimed to investigate the diagnostic utility and appropriate diagnostic cut-offs of three short dependence measures among long-term cannabis users. SETTING AND PARTICIPANTS Two hundred long-term, regular cannabis users were recruited and interviewed in Sydney, Australia. MEASUREMENTS Receiver Operating Characteristic analyses compared the diagnostic performance of the short University of Michigan CIDI, a measure of ICD-10 dependence and the Severity of Dependence Scale against the "gold standard" of moderate or more severe DSM-III-R cannabis dependence, as diagnosed by the Substance Abuse Module of the CIDI. FINDINGS The measures were of equal utility in diagnosing at least moderate DSM-III-R cannabis dependence. While the optimal diagnostic cut-offs for the short University of Michigan CIDI and the ICD-10 dependence measure remained unchanged from those conventionally applied, a more liberal cut-off was optimal for the Severity of Dependence Scale. The amended prevalence of cannabis dependence was 77% using the short University of Michigan CIDI, 72% by the ICD-10 measure and 62% by the Severity of Dependence Scale. CONCLUSIONS The three instruments were able to diagnose cannabis dependence at levels substantially better than chance. They were generally robust in terms of the optimal diagnostic cut-off in a population of long-term cannabis users. This paper provides guidelines for choosing optimal cut-offs within different contexts.
Physiologic and psychological symptoms experienced by adults with acute leukemia: an integrative literature review.

PURPOSE/OBJECTIVES To evaluate the current knowledge of symptoms experienced by adults with acute leukemia (AL) and provide evidence to inform practice and research. DATA SOURCES Literature review using an electronic search supplemented by a hand search of current literature reporting the physiologic and/or psychological symptoms of patients with AL was conducted. DATA SYNTHESIS Because of the variability found in the methods and specific aims of the articles, a rating system was applied to score how strongly the findings contributed to meeting the aims of the research. This rating system was applied to assist the authors in analyzing the findings. Therefore, the articles that scored lower ultimately contributed less during the analysis phase. CONCLUSIONS Knowledge regarding the symptoms experienced by adults undergoing treatment is being slowly evaluated. However, to better understand and subsequently manage these symptoms, longitudinal research examining the symptom trajectories in this population is needed. IMPLICATIONS FOR NURSING Additional investigation into symptom characteristics will facilitate the development of tailored interventions to manage the temporal characteristics of symptoms for this population.
Arthritis burden and impact are greater among U.S. women than men: intervention opportunities.

OBJECTIVES To summarize arthritis burden and impact among women compared with men, using updated surveillance and impact measures; to describe public health approaches to arthritis; and to review effective, evidence-based arthritis self-management interventions. RESULTS Arthritis continues to burden the U.S. population as the leading cause of physical disability and affects women disproportionately: women with arthritis report greater prevalence of activity and work limitations, psychological distress, and severe joint pain than their male counterparts. Three main public health interventions can reduce arthritis impact: self-management education, physical activity, and weight management. Self-management education programs are proven to reduce pain and depression, delay disability, improve self-efficacy, physical function, and quality of life, and reduce healthcare costs. Appropriate physical activity decreases pain, improves function, and delays disability. The American College of Rheumatology recommends maintaining a healthy weight to benefit patients with hip or knee osteoarthritis. Women appear more receptive to certain information delivery methods (i.e., physician counseling) than men, suggesting gender-specific targeting of interventions may be of use. CONCLUSIONS Effective interventions remain underused. The Centers for Disease Control and Prevention Arthritis Program and its partners, including state arthritis programs, continue their efforts to build the arthritis public health science base, monitor burden and impact, evaluate and disseminate evidence-based interventions, and work to decrease and delay disability, and increase quality of life among those with arthritis. As new approaches are developed, women and other disproportionately impacted groups merit particular consideration in tailoring and delivering programs to reduce arthritis burden.
The impact of shifting vantage perspective when recalling and imagining positive events

The vantage perspective from which memories are recalled influences their emotional impact. To date, however, the impact of vantage perspective on the emotions elicited by positive memories and images of positive future events has been minimally explored. We experimentally manipulated the vantage perspective from which a sample of undergraduate students (n =80) recalled positive memories and imagined positive future events. Participants who naturally recalled their positive memories from a field perspective reported decreased vividness and positive affect (i.e., happiness, optimism, hopefulness) when they were instructed to shift to an observer perspective. The same pattern of emotionality ratings was observed when participants' vantage perspective of imagined future events was manipulated. In contrast, shifting participants from observer to field perspective recall of positive memories did not result in changes in ratings of memory-related emotion, although we found an unexpected trend towards reduced vividness. For positive future events, shifting from an observer to a field perspective resulted in decreased vividness but did not lead to any changes in positive emotion. Our findings confirm that vantage perspective plays a key role in determining the emotional impact of positive memories, and demonstrate that this relationship is also evident for images of future positive events.
Trends in Seniors' Use of Digital Health Technology in the United States, 2011-2014.

Trends in Seniors’ Use of Digital Health Technology in the United States, 2011-2014 The sickest, most expensive, and fastest growing segment of the US population are seniors 65 years and older.1 Digital health technology has been advocated as a solution to improve health care quality, cost, and safety. However, little is known about digital health use among seniors. Methods | The Partners HealthCare Human Research Committee exempted this study from review. The National Health and Aging Trends Study (NHATS) is an annual in-home, computerassisted, longitudinal, nationally representative survey of community-dwelling Medicare beneficiaries 65 years and older drawn from the Medicare enrollment database through a complex sampling design.2 Each year, NHATS asks the same respondents about everyday (nonhealth) technology use and 4 digital health modalities: use of the internet to fill prescrip-
Hepatitis E virus infection in Europe: surveillance and descriptive epidemiology of confirmed cases, 2005 to 2015

Hepatitis E virus (HEV) is an under-recognised cause of acute hepatitis in high-income countries. The purpose of this study was to provide an overview of testing, diagnosis, surveillance activities, and data on confirmed cases in the European Union/European Economic Area (EU/EEA). A semi-structured survey was developed and sent to 31 EU/EEA countries in February 2016, 30 responded. Twenty of these countries reported that they have specific surveillance systems for HEV infection. Applied specific case definition for HEV infection varied widely across countries. The number of reported cases has increased from 514 cases per year in 2005 to 5,617 in 2015, with most infections being locally acquired. This increase could not be explained by additional countries implementing surveillance for HEV infections over time. Hospitalisations increased from less than 100 in 2005 to more than 1,100 in 2015 and 28 fatal cases were reported over the study period. EU/EEA countries are at different stages in their surveillance, testing schemes and policy response to the emergence of HEV infection in humans. The available data demonstrated a Europe-wide increase in cases. Standardised case definitions and testing policies would allow a better understanding of the epidemiology of HEV as an emerging cause of liver-related morbidity.
Comparative isolation and genetic diversity of Arcobacter sp. from fish and the coastal environment

Arcobacter species are emerging food‐borne and water‐borne human pathogens associated mostly with food animals and their environment. The present study was aimed to isolate Arcobacter species from fish, shellfish and coastal water samples using two methods and to determine their genetic diversity. Of 201 samples of fish, shellfish and water samples analysed, 66 (32·8%) samples showed the presence of Arcobacter DNA from both Arcobacter enrichment broth and Bolton broth. Arcobacters were isolated from 58 (87·8%) and 38 (57·5%) of Arcobacter DNA‐positive samples using Arcobacter blood agar and Preston blood agar, respectively. Arcobacter sp. identified by biochemical tests were further analysed by a genus‐specific PCR, followed by a multiplex‐PCR and 16S rRNA‐RFLP. From both the methods, four different Arcobacter species namely Arcobacter butzleri, Arcobacter skirrowii, Arcobacter mytili and Arcobacter defluvii were isolated, of which A. butzleri was the predominant species. Enterobacterial repetitive intergenic consensus (ERIC)‐PCR fingerprint analysis revealed that the arcobacters isolated in this study were genetically very diverse and no specific genotype was found associated with a specific source (seafood or water). Since pathogenic arcobacters are not known to be natural inhabitants of coastal marine environment, identifying the sources of contamination will be crucial for effective management of this problem.
Differences in fatigue by treatment methods in women with breast cancer.

PURPOSE/OBJECTIVES To investigate the differences between various cancer therapies (radiation, hormonal, chemotherapy, and their combinations) and the specific dimensions of fatigue (affective meaning, behavioral/severity, cognitive/mood, and sensory). DESIGN Descriptive, cross-sectional, mailed survey design. SAMPLE AND SETTING Data were collected from women who were breast cancer survivors and members of a nonprofit educational organization in the North-east. Criteria for this study included no self-reported disease recurrence, and treatment was within 18 months prior to the mailed survey (N = 322). The typical participant was middle-aged (mean = 52.2; SD = 10.3), Caucasian (93%), postmenopausal (55%), and diagnosed with cancer 2.42 (SD = 2.6) years prior to the study. METHODS Secondary data analysis from a study using the Piper Fatigue Scale. VARIABLES Level of fatigue. FINDINGS Significant differences were found by treatment in total fatigue scores (p < 0.03) and cognitive/mood scores (p < 0.05). Women who received combination therapy had the highest fatigue scores (mean = 4.8; SD = 2.0); those who received only radiation therapy had the lowest fatigue scores (mean = 2.7; SD = 2.0). CONCLUSIONS Fatigue in breast cancer survivors varies by type of cancer therapy. Future studies are needed to investigate the relationships between fatigue and hormonal therapy, and they need to be designed to examine changes over time. IMPLICATIONS FOR NURSING PRACTICE Study findings advance knowledge about fatigue in women with breast cancer and aid nurses in providing anticipatory guidance for women undergoing different treatment regimens.
Oleosin of Plant Seed Oil Bodies Is Correctly Targeted to the Lipid Bodies in Transformed Yeast*

Yeast (Saccharomyces cerevisiae) has been used extensively as a heterologous eukaryotic system to study the intracellular targeting of proteins to different organelles. The lipid bodies in yeast have not been previously subjected to such studies. These organelles are functionally equivalent to the subcellular storage oil bodies in plant seeds. A plant oil body has a matrix of oils (triacylglycerols) surrounded by a layer of phospholipids embedded with abundant structural proteins called oleosins. We tested whether plant oleosin could be correctly targeted to the lipid bodies in transformed yeast. The coding region of a maize (Zea mays L.) oleosin gene was incorporated into yeast high copy and low copy number plasmids in which its expression was under the control of GAL1 promoter. Yeast strains transformed with these plasmids produced oleosin when grown in a medium containing galactose but not glucose. The oleosin produced in yeast had a molecular mass slightly higher than that of the native protein in maize. Oleosin accumulated concomitantly with the storage lipids during growth of the transformed yeast, and it was not secreted. Subcellular fractionation of the cell extracts obtained by two different cell breakage procedures revealed that the oleosin was largely restricted to the lipid bodies. Oleosin apparently did not affect the lipid contents and composition of the transformed yeast lipid bodies but replaced some of the native proteins associated with the organelles. Immunocytochemistry of the transformed yeast cells showed that the oleosin was present mostly on the periphery of the lipid bodies. Oleosin isolated from maize or transformed yeast strain, alone or in the presence of phospholipids or SDS, did not bind to the yeast lipid bodies in vitro We conclude that plant oleosin is correctly targeted to the lipid bodies in transformed yeast and that yeast may be used as a heterologous system to dissect the intracellular targeting signals in the oleosin.
