Incidence, risk factors and hospital burden in children under five years of age hospitalised with respiratory syncytial virus infections. - Acta paediatrica (Oslo, Norway : 1992)
Respiratory syncytial virus (RSV) infections are among the most common lower respiratory tract infections in infants, but few studies have determined the age-specific incidence of hospitalisation in defined populations. This study gathered Swedish data on RSV in Gothenburg and its 10 surrounding municipalities from 2004 to 2011.Information was obtained from hospital databases of all patients up to five years of age who had a discharge diagnosis of an RSV infection and had a positive antigen detection or polymerase chain reaction test.A total of 1764 children fulfilled the inclusion criteria and 238 of these were preterm. The incidence under one year of age was 17.4/1000/year, and in children aged one to four years it was 0.6/1000/year. RSV patients occupied a mean of 1141 hospital beds per year: 65 were treated in the intensive care unit, 27 needed ventilator support, 19 needed continuous positive airway pressure, 408 (23%) received antibiotics, 399 (23%) received steroids, and all but four patients received a bronchodilator. All children survived.The incidence of RSV infections was high, medication use was high, and complications were low. Preterm infants had a higher risk, but most infants needing hospitalisation for RSV are full term and have no known risk factors.©2015 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.
The impact of HIV-associated anaemia on the incidence of red blood cell transfusion: implications for blood services in HIV-endemic countries. - Transfusion and apheresis science : official journal of the World Apheresis Association : official journal of the European Society for Haemapheresis
Cytopaenias, especially anaemia, are common in the HIV-infected population. The causes of HIV related cytopaenias are multi-factorial and often overlapping. In addition, many of the drugs used in the management of HIV-positive individuals are myelosuppresive and can both cause and exacerbate anaemia. Even though blood and blood products are still the cornerstone in the management of severe cytopaenias, how HIV may affect blood utilisation is not well understood. The impact of HIV/AIDS on blood collections has been well documented. As the threat posed by HIV on the safety of the blood supply became clearer, South Africa introduced progressively more stringent donor selection criteria, based on the HIV risk profile of the donor cohort from which the blood collected. The implementation of new testing technology in 2008 which significantly improved the safety of the blood supply enabled the removal of what was perceived by many as a racially based donor risk model. However, this new technology had a significant and sustained impact on the cost of blood and blood products in South Africa. In contrast, it would appear little is known of how HIV influences the utilisation of blood and blood products. Considering the high prevalence of HIV among hospitalised patients and the significant risk for anaemia among this group, there would be an expectation that the transfusion requirements of an HIV-infected patient would be higher than that of an HIV-negative patient. However, very little published data is available on this topic which emphasises the need for further large-scale studies to evaluate the impact of HIV/AIDS on the utilisation of blood and blood products and how the large-scale roll-out of ARV programs may in future play a role in determining the country's blood needs.Copyright © 2014 Elsevier Ltd.

Global transcriptome analysis of Atlantic cod (Gadus morhua) liver after in vivo methylmercury exposure suggests effects on energy metabolism pathways. - Aquatic toxicology (Amsterdam, Netherlands)
Methylmercury (MeHg) is a widely distributed contaminant polluting many aquatic environments, with health risks to humans exposed mainly through consumption of seafood. The mechanisms of toxicity of MeHg are not completely understood. In order to map the range of molecular targets and gain better insights into the mechanisms of toxicity, we prepared Atlantic cod (Gadus morhua) 135k oligonucleotide arrays and performed global analysis of transcriptional changes in the liver of fish treated with MeHg (0.5 and 2 mg/kg of body weight) for 14 days. Inferring from the observed transcriptional changes, the main pathways significantly affected by the treatment were energy metabolism, oxidative stress response, immune response and cytoskeleton remodeling. Consistent with known effects of MeHg, many transcripts for genes in oxidative stress pathways such as glutathione metabolism and Nrf2 regulation of oxidative stress response were differentially regulated. Among the differentially regulated genes, there were disproportionate numbers of genes coding for enzymes involved in metabolism of amino acids, fatty acids and glucose. In particular, many genes coding for enzymes of fatty acid beta-oxidation were up-regulated. The coordinated effects observed on many transcripts coding for enzymes of energy pathways may suggest disruption of nutrient metabolism by MeHg. Many transcripts for genes coding for enzymes in the synthetic pathways of sulphur containing amino acids were also up-regulated, suggesting adaptive responses to MeHg toxicity. By this toxicogenomics approach, we were also able to identify many potential biomarker candidate genes for monitoring environmental MeHg pollution. These results based on changes on transcript levels, however, need to be confirmed by other methods such as proteomics.Copyright © 2012 Elsevier B.V. All rights reserved.
Water administration and the risk of syncope and presyncope during blood donation: a randomized clinical trial. - Transfusion
Blood centers rely heavily on adolescent donors to meet blood demand, but presyncope and syncope are more frequent in younger donors. Studies have suggested administration of water before donation may reduce syncope and/or presyncope in this group.We conducted a randomized, controlled trial to establish the effect of preloading with 500 mL of water on the rate of syncope and presyncope in adolescent donors. School collection sites in Eastern Cape Province of South Africa were randomized to receive water or not. Incidence of syncope and presyncope was compared between randomization groups using multivariable logistic regression.Of 2464 study participants, 1337 received water and 1127 did not; groups differed slightly by sex and race. Syncope or presyncope was seen in 23 (1.7%) of the treatment and 18 (1.6%) of the control arm subjects. After adjusting for race, sex, age, and donation history, there was no difference in outcome between the water versus no water arms (adjusted odds ratio [OR], 0.80; 95% confidence interval [CI], 0.42-1.53). Black donors had sevenfold lower odds of syncope or presyncope than their white counterparts (adjusted OR, 0.14; 95% CI, 0.04-0.47).Preloading adolescent donors with 500 mL of water did not have a major effect in reducing syncope and presyncope in South African adolescent donors. Our adolescent donors had lower overall syncope and presyncope rates than similar populations in the United States, limiting the statistical power of the study. We confirmed much lower rates of syncope and presyncope among young black donors.© 2012 American Association of Blood Banks.
Brain proteome alterations of Atlantic cod (Gadus morhua) exposed to PCB 153. - Aquatic toxicology (Amsterdam, Netherlands)
Polychlorinated biphenyls (PCBs) are still widespread environmental pollutants that bioaccumulate and biomagnify in the aquatic food chains despite the ban on their production. They constitute a class of 209 possible congeners with different chlorination pattern of the biphenyl ring structure resulting in many different toxicities and mechanisms of toxicity. The neurotoxicity of PCBs is relatively poorly understood, and biomarkers for their neurotoxic effects are lacking. We have carried out a proteomic analysis of brain tissue from Atlantic cod (Gadus morhua) exposed to 2,2',4,4',5,5'-hexachlorobiphenyl (PCB 153, ortho-substituted and non-coplanar), a previously demonstrated neurotoxic congener and the most prevalent congener in biological samples. The fish received 0, 0.5, 2 and 8 mg/kg PCB 153 by intraperitoneal injection, half of the dose on the first day and the second half after one week, and were exposed for two weeks in total. Using a 2-DE approach we found 56 protein spots to be 20% or more (≤ 0.8-fold or ≥ 1.2-fold) significantly different between at least one of the three PCB 153-exposed groups and the control group, and 27 of these were identified by MALDI-TOF MS and MS/MS. Approximately 80% of the differentially regulated proteins may be associated with a non stressor-specific response and/or have previously been classified as notoriously differentially regulated in 2-DE/MS based proteomics studies, such as alterations/responses in energy metabolism, cytoskeleton, protein synthesis, protein degradation (ubiquitin-proteasome system), cellular growth, cycle and death (14-3-3 protein), and (surprisingly) axon guidance (dihydropyrimidinase-like 2 (=collapsin response mediator protein 2, CRMP-2)). The six remaining affected proteins include the strongest up-regulated protein, pyridoxal kinase (essential for synthesis of neurotransmitters such as dopamine, serotonin and GABA), nicotinamide phosphoribosyl-transferase (involved in protection against axonal degeneration) and protein phosphatase 1 (controls brain recovery by synaptic plasticity). The last three of these six proteins (deltex, Rab14 and sorting nexin 6) may preliminarily identify involvement of the Notch signaling pathway and endosomal function in PCB 153-induced neurotoxicity. Our findings constitute novel clues for further research on PCB 153 mode of action in brain, and a proper selection of proteins may, following validation, be applicable in a panel of biomarkers for aquatic environmental monitoring.Copyright © 2011 Elsevier B.V.

Integrative environmental genomics of Cod (Gadus morhua): the proteomics approach. - Journal of toxicology and environmental health. Part A
Atlantic cod (Gadus morhua) is an essential species in North Atlantic fisheries and increasingly relevant as an aquaculture species. However, potential conflicts with both coastal industry and petroleum industry expanding into northern waters make it important to understand how effluents (produced water, pharmaceuticals, food contaminants, and feed contaminants) affect the growth, reproduction, and health of this species in order to maintain a sustainable cod population and a healthy human food source, and to discover biomarkers for environmental monitoring and risk assessment. The ongoing genome sequencing effort of Atlantic cod has opened the possibility for a systems biology approach to elucidate molecular mechanisms of toxicity. Our study aims to be a first step toward such a systems toxicology understanding of genomic responses to environmental insults. A toxicogenomic approach was initiated that is combining data generated from proteomics analyses and transcriptomics analyses, and the concurrent development of searchable expressed sequence tags (EST) databases and genomic databases. This interdisciplinary study may also open new possibilities of gene annotation and pathway analyses.
Responses in the brain proteome of Atlantic cod (Gadus morhua) exposed to methylmercury. - Aquatic toxicology (Amsterdam, Netherlands)
The molecular mechanisms underlying the neurotoxicity of methylmercury (MeHg), a ubiquitous environmental contaminant, are not yet fully understood. Furthermore, there is a lack of biomarkers of MeHg neurotoxicity for use in environmental monitoring. We have undertaken a proteomic analysis of brains from Atlantic cod (Gadus morhua) exposed to 0, 0.5 and 2 mg/kg MeHg administered by intraperitoneal injection. The doses were given in two injections, half of the dose on the first day and the second half after 1 week, and the total exposure period lasted 2 weeks. Using 2-DE coupled with MALDI-TOF MS and MS/MS, we observed the level of 71 protein spots to be 20% or more significantly altered following MeHg exposure, and successfully identified 40 of these protein spots. Many of these proteins are associated with main known molecular targets and mechanisms of MeHg-induced neurotoxicity in mammals, such as mitochondrial dysfunction, oxidative stress, altered calcium homeostasis and tubulin/disruption of microtubules. More interestingly, several of the affected proteins, with well-established or recently demonstrated critical functions in nervous system-specific processes, have not previously been associated with MeHg exposure in any species. These proteins include the strongest up-regulated protein, pyridoxal kinase (essential for synthesis of several neurotransmitters), G protein (coupled to neurotransmitter receptors), nicotinamide phosphoribosyl-transferase (protection against axonal degeneration), dihydropyrimidinase-like 5 (or collapsin response mediator protein 5, CRMP-5) (axon guidance and regeneration), septin (dendrite development), phosphatidylethanolamine binding protein (precursor for hippocampal cholinergic neurostimulating peptide) and protein phosphatase 1 (control of brain recovery by synaptic plasticity). The results of the present study aid our understanding of molecular mechanisms underlying MeHg neurotoxicity and defense responses, and provide a large panel of protein biomarker candidates for aquatic environmental monitoring.2010 Elsevier B.V.

Comparison of the microsatellite instability analysis system and the Bethesda panel for the determination of microsatellite instability in colorectal cancers. - The Journal of molecular diagnostics : JMD
Microsatellite instability (MSI) analysis of colorectal cancers is clinically useful to identify patients with hereditary nonpolyposis colorectal cancer (HNPCC) caused by germline mutations of mismatch repair genes. MSI status may also predict cancer response/resistance to certain chemotherapies. We evaluated the MSI Analysis System (Promega Corp.; five mononucleotide and two pentanucleotide repeats) and compared the results to the Bethesda panel, which interrogates five microsatellite loci recommended by the 1997 National Cancer Institute-sponsored MSI workshop (three dinucleotide and two mononucleotide repeats). Thirty-four colorectal cancers were analyzed by both assays. The overall concordance between the two assays was 85% (29 of 34). There was complete concordance between the two assays for all of the MSI-high (11 of 11) and microsatellite stable (MSS; 18 of 18) cases. In the 11 MSI-high cases, all 5 of the mononucleotide loci in the MSI Analysis System demonstrated shifted alleles (100% sensitivity), and each shift resulted in products that were smaller in size than the germline alleles. All (5 of 5) of the cases interpreted as MSI-low by the Bethesda assay were interpreted as MSS by the MSI Analysis System. Our results suggest that the MSI Analysis System is generally superior and may help resolve cases of MSI-low into either MSI-high or MSS.
Overexpression of claudin proteins in esophageal adenocarcinoma and its precursor lesions. - Applied immunohistochemistry & molecular morphology : AIMM / official publication of the Society for Applied Immunohistochemistry
Claudins are components of tight junctions important in intercellular barriers and cell polarity. The authors identified upregulation of Claudins 3, 4, and 7 in gastric adenocarcinoma using Affymetrix U-133 oligonucleotide microarrays and immunohistochemistry (IHC). While normal gastric mucosa lacked Claudin 3, 4, and 7 expression, intestinal metaplasia and dysplasia showed these proteins. The authors hypothesized that Claudins would be similarly overexpressed in Barrett's esophagus (BE)/adenocarcinoma. Claudins 3, 4, and 7 gene expression was analyzed by Affymetrix U-133 microarrays in three esophageal adenocarcinomas, one case of BE, and three normal esophagi. IHC validation was performed using tissue microarrays constructed from esophageal resection specimens containing squamous (44 cases), gastric (40 cases), and non-dysplastic BE (16 cases), low-grade and high-grade dysplasia (16 and 26 cases), adenocarcinoma (58 cases), and nodal metastases (27 cases). IHC staining was scored semiquantitatively (0+ to 4+). By microarray analysis, Claudin 3 showed a marked increase in mRNA expression compared with normal esophagus (approximately 100-fold). Claudins 4 and 7 were modestly increased (2.2- and 1.3-fold). By IHC, Claudin 3 expression was 1+ in most (>95%) normal squamous or gastric tissues and 2+ to 4+ in more than 80% of high-grade dysplasia, adenocarcinoma, and metastases specimens. Claudin 4 protein expression was 2+ or less in most squamous and gastric mucosa (>90%) but 3+ or 4+ in BE, low- and high-grade dysplasia, adenocarcinoma, and metastases specimens (>90%). Claudin 7 expression was minimal in squamous and gastric mucosa but strong (3+ to 4+) in BE and low-grade dysplasia. In high-grade dysplasia, adenocarcinoma, and metastases, Claudin 7 was less intense, with 60% to 70% staining 3+ or 4+ and 30% to 40% staining weakly (1+ or 2+). The findings suggest that alterations in Claudin proteins are an early event in tumorigenesis and may provide targets for diagnosis and directed therapy for esophageal adenocarcinoma and its precursors.
Local stakeholders' acceptance of model-generated data used as a communication tool in water management: The Rönneå Study. - Ambio
The objective of this study was to increase the knowledge of local stakeholders' acceptance of model-generated data when used as a communication tool in water quality management. The Rönneå catchment in the southwest of Sweden was chosen as the study area. The results indicate the model-generated data served as a uniting factor. Simultaneously, the stakeholders were concerned with presented data, the main problems being sources of pollution, which were not accounted for, lack of trustworthiness when measuring pollution, and the uncertainty of the impact of natural variation and delayed effects. Four clusters of factors were identified as influencing stakeholders' acceptance of the model-generated data: confidence in its practical applications, confidence in the people involved in or providing material for the dialog (such as experts, decision-makers, and media), the social characteristics of the participants (such as age and profession), and the way of communicating the data (such as tone of communication, group composition, duration, and geographical scope of the dialog). The perception of the fairness of the practical application of given model-generated data was also an important factor for acceptance.
