Molecular diagnostics of gliomas: the clinical perspective.

Significant progress has been made in the molecular diagnostic subtyping of brain tumors, in particular gliomas. In contrast to the classical molecular markers in this field, p53 and epidermal growth factor receptor (EGFR) status, the clinical significance of which has remained controversial, at least three important molecular markers with clinical implications have now been identified: 1p/19q codeletion, O⁶-methylguanine methyltransferase (MGMT) promoter methylation and isocitrate dehydrogenase-1 (IDH1) mutations. All three are favorable prognostic markers. 1p/19q codeletion and IDH1 mutations are also useful to support and extend the histological classification of gliomas since they are strongly linked to oligodendroglial morphology and grade II/III gliomas, as opposed to glioblastoma, respectively. MGMT promoter methylation is the only potentially predictive marker, at least for alkylating agent chemotherapy in glioblastoma. Beyond these classical markers, the increasing repertoire of anti-angiogenic agents that are currently explored within registration trials for gliomas urgently calls for efforts to identify molecular markers that predict the benefit derived from these novel treatments, too.

07043-017 North Fork Maquoketa Final Report

The North Fork Maquoketa River Headwaters (NFMRH) has been identified as impaired by nutrients, episodic slugs of ammonia and sediment. The NFMRH TMDL plan calls for a "phasing approach" to managing water quality when the origin is non-point source contaminants. This project will address phase 1 using a performance reward program for targeted cooperators to improve environmental index scores using cost-share, EQIP practices and flexible management alternatives. Pre-project assessments suggest that rewards should target refined management of erosion-prone fields and farms with livestock populations, which contribute to the P and N loads responsible for fertilizing filamentous algae blooms that depress dissolved oxygen concentrations in the NFMRH. The Phosphorus Index, Soil Conditioning Index and cornstalk nitrate test will be used by producers to determine effective alternatives, such as no-till planting, to reduce nutrient and sediment delivery. These evironmental indexes will be especially useful for livestock producers in the livestock dense watershed. This project will extend a NRCS-sponsored Conservation Innovation Grant currently offered to producers in the Coffee Creek sub-watershed to a three-year, watershed-wide effort that will be necessary to make significant improvements in environmental management.

Hospital outbreak of methicillin-resistant Staphylococcus aureus caused by a new, possibly hyperepidemic variant from a previously sporadic strain.

Objective: To describe an ongoing outbreak that tripled the annual detection of methicillin-resistant Staphylococcus aureus (MRSA) carriage in a tertiary care hospital. Methods: Active surveillance of MRSA is performed since 20 years in our hospital. Our protocol includes screening of patients transferred from high-incidence health-care institutions or countries, roommates of new MRSA cases, and wards where _2 patients acquired MRSA during the same week. Contact precautions are used for known carriers. PFGE was used for molecular typing until 2004, and was then replaced by Double-Locus Sequence Typing (DLST). Results: A median yearly incidence of 173 new carriers of MRSA was observed from 2002 to 2007. Since September 2008, an increasing number of new cases were observed, mainly as successive clusters limited to distinct wards, reaching a total of 398 until October 2009. The yearly incidence of new cases rose to 275 in 2008 and 613 in 2009. 60% of the cases were due to one strain: DLST 4−4, ST 228, SCCmecI. The incidence of new cases due to the previously predominant strains remained unchanged. The epidemic strain corresponded to a new variant of a clone responsible for a previous outbreak in 2001, and only sporadically isolated (mean of 20 cases/year) since then. A case- control study documented a significant association between acquisition of the epidemic strain and a stay in intensive and intermediary care units, a highest number of internal transfers, but did not identify a point source of transmission. Infection control practices and antibiotic policy had remained unchanged for several years. Compliance with handhygiene as monitored yearly was on the rise. Screening of 313 healthcare workers only found one carrier of the epidemic strain lately in the outbreak. Additional infection control measures were enforced, including screening at ICU admission and discharge with PCR-based rapid test, routine screening for all patients leaving epidemic wards, introduction of PCR-based rapid test for contact tracing, additional working forces for environmental disinfection, and hospital-wide education of healthcare workers. However, the outbreak was still ongoing after 5 months. Conclusions: Factors linked to the dissemination of this new variant in our institution remain undetermined. This unresolved outbreak suggests that this new variant acquired hyperepidemic properties, which calls for further investigations.

Isozymic variability in a Brazilian collection of annatto (Bixa orellana L.)

The objectives of this work were to optimize the isozyme electrophoresis technique for Bixa orellana, and use isozyme markers for a preliminary survey on the genetic variability in Brazilian annatto germplasm accessions. Collection consisted of seed samples from sixty open pollinated trees, representing two Northern and four Southern geographic provenances. The extraction, electrophoresis, and interpretation of annatto isozymes are described. Three out of the twenty-one identified isozyme loci were polymorphic in the collection. The percentage of polymorphic loci (P = 21.05) and the expected heterozygosity in annatto (H T = 0.064) were low, compared to other tropical woody species. A UPGMA phenogram, constructed with Nei's genetic distances, clearly separated the germplasm provenant from North and Central Brazil. Variability was significantly higher among the accessions from Maranhão. A sharp genetic differentiation was detected between accessions from Maranhão and Pará States, despite their geographical proximity. The distinctive isozyme polymorphism, observed in the accessions from Maranhão, together with reports on local morphological heterogeneity in annatto fruit shape, color, and pubescence, calls for more detailed genetic and taxonomic investigation.

Are niche-based species distribution models transferable in space?

Aim To assess the geographical transferability of niche-based species distribution models fitted with two modelling techniques. Location Two distinct geographical study areas in Switzerland and Austria, in the subalpine and alpine belts. Methods Generalized linear and generalized additive models (GLM and GAM) with a binomial probability distribution and a logit link were fitted for 54 plant species, based on topoclimatic predictor variables. These models were then evaluated quantitatively and used for spatially explicit predictions within (internal evaluation and prediction) and between (external evaluation and prediction) the two regions. Comparisons of evaluations and spatial predictions between regions and models were conducted in order to test if species and methods meet the criteria of full transferability. By full transferability, we mean that: (1) the internal evaluation of models fitted in region A and B must be similar; (2) a model fitted in region A must at least retain a comparable external evaluation when projected into region B, and vice-versa; and (3) internal and external spatial predictions have to match within both regions. Results The measures of model fit are, on average, 24% higher for GAMs than for GLMs in both regions. However, the differences between internal and external evaluations (AUC coefficient) are also higher for GAMs than for GLMs (a difference of 30% for models fitted in Switzerland and 54% for models fitted in Austria). Transferability, as measured with the AUC evaluation, fails for 68% of the species in Switzerland and 55% in Austria for GLMs (respectively for 67% and 53% of the species for GAMs). For both GAMs and GLMs, the agreement between internal and external predictions is rather weak on average (Kulczynski's coefficient in the range 0.3-0.4), but varies widely among individual species. The dominant pattern is an asymmetrical transferability between the two study regions (a mean decrease of 20% for the AUC coefficient when the models are transferred from Switzerland and 13% when they are transferred from Austria). Main conclusions The large inter-specific variability observed among the 54 study species underlines the need to consider more than a few species to test properly the transferability of species distribution models. The pronounced asymmetry in transferability between the two study regions may be due to peculiarities of these regions, such as differences in the ranges of environmental predictors or the varied impact of land-use history, or to species-specific reasons like differential phenotypic plasticity, existence of ecotypes or varied dependence on biotic interactions that are not properly incorporated into niche-based models. The lower variation between internal and external evaluation of GLMs compared to GAMs further suggests that overfitting may reduce transferability. Overall, a limited geographical transferability calls for caution when projecting niche-based models for assessing the fate of species in future environments.

Grau de satisfacció d'un col·lectiu de persones grans en relació a l'atenció rebuda dels professionals d'infermeria durant la seva hospitalització

Introducció: La preocupació per la qualitat assistencial, i concretament per la qualitat de les cures infermeres, la satisfacció percebuda pel pacient com element fonamental com a indicador de la qualitat dels serveis sanitaris i clau en la millora de la qualitat assistencial, i el fet que a l’estat espanyol hi ha pocs estudis de satisfacció específics de la població anciana hospitalitzada, ens va portar a plantejar un estudi amb l’objectiu de valorar el grau de satisfacció de les persones grans hospitalitzades en relació a l’atenció rebuda dels professionals d’infermeria. Metodologia: S’ha realitzat un estudi descriptiu i transversal en un col.lectiu de 42 persones hospitalitzades d’edat ≥ 60 anys. El grau de satisfacció es va determinar amb “La Monica Oberst Patient Satisfaction Scale 12” (LOPSS 12), versió reduïda en castellà. La personalització de les cures es va valorar amb un qüestionari que valora la relació infermera-usuari extret de l’Índex de Personalització de les Cures. L'anàlisi estadística es va dur a terme amb el programa informàtic SPSS® vs 21.0. Resultats: Es va evidenciar un elevat grau de satisfacció global amb les cures d’infermeria (8,8  1,5 / 10), però el nivell global de personalització d’aquestes cures no va ser molt satisfactori (3,4  2,1 / 7). Els homes van valorar millor a les infermeres respecte a que consideraven les seves opinions i preferències (p=0,03) i contestaven amb rapidesa les seves trucades (p=0,009). La personalització de les cures millorava conforme incrementava el grau de satisfacció global (r = 0,582; p = 0,000) i amb el temps d’hospitalització (r = 0,344; p = 0,026). Conclusions: El grau de satisfacció global respecte la satisfacció en l’atenció rebuda per part d’infermeria, va ser elevat però amb baix grau de personalització, mostrant major satisfacció els homes respecte les dones. Conèixer l’opinió dels usuaris representa una oportunitat pels professionals de reflexionar sobre la pràctica clínica i ser crítics per avançar en el desenvolupament de la professió, identificant aspectes susceptibles de millora 5 amb la finalitat d’augmentar la qualitat de les cures que es presten, així com la qualitat de vida de les persones.

Mission-Oriented Dust Control and Surface Improvement Processes for Unpaved Roads, HR-194, 1981

Six subject areas prompted the broad field of inquiry of this mission-oriented dust control and surface improvement project for unpaved roads: • DUST--Hundreds of thousands of tons of dust are created annually by vehicles on Iowa's 70,000 miles of unpaved roads and streets. Such dust is often regarded as a nuisance by Iowa's highway engineers. • REGULATIONS--Establishment of "fugitive dust" regulations by the Iowa DEQ in 1971 has created debates, conferences, legal opinions, financial responsibilities, and limited compromises regarding "reasonable precaution" and "ordinary travel," both terms being undefined judgment factors. • THE PUBLIC--Increased awareness by the public that regulations regarding dust do in fact exist creates a discord of telephone calls, petitions, and increasing numbers of legal citations. Both engineers and politicians are frustrated into allowing either the courts or regulatory agencies to resolve what is basically a professional engineering responsibility. • COST--Economics seldom appear as a tenet of regulatory strategies, and in the case of "fugitive dust," four-way struggles often occur between the highway professions, political bodies, regulatory agencies, and the general public as to who is responsible, what can be done, how much it will cost, or why it wasn't done yesterday. • CONFUSION--The engineer lacks authority, and guidelines and specifications to design and construct a low-cost surf acing system are nebulous, i.e., construct something between the present crushed stone/gravel surface and a high-type pavement. • SOLUTION--The engineer must demonstrate that dust control and surface improvement may be engineered at a reasonable cost to the public, so that a higher degree of regulatory responsibility can be vested in engineering solutions.

GuavaH: a compendium of host genomic data in HIV biology and disease.

BACKGROUND: There is an ever-increasing volume of data on host genes that are modulated during HIV infection, influence disease susceptibility or carry genetic variants that impact HIV infection. We created GuavaH (Genomic Utility for Association and Viral Analyses in HIV, http://www.GuavaH.org), a public resource that supports multipurpose analysis of genome-wide genetic variation and gene expression profile across multiple phenotypes relevant to HIV biology. FINDINGS: We included original data from 8 genome and transcriptome studies addressing viral and host responses in and ex vivo. These studies cover phenotypes such as HIV acquisition, plasma viral load, disease progression, viral replication cycle, latency and viral-host genome interaction. This represents genome-wide association data from more than 4,000 individuals, exome sequencing data from 392 individuals, in vivo transcriptome microarray data from 127 patients/conditions, and 60 sets of RNA-seq data. Additionally, GuavaH allows visualization of protein variation in ~8,000 individuals from the general population. The publicly available GuavaH framework supports queries on (i) unique single nucleotide polymorphism across different HIV related phenotypes, (ii) gene structure and variation, (iii) in vivo gene expression in the setting of human infection (CD4+ T cells), and (iv) in vitro gene expression data in models of permissive infection, latency and reactivation. CONCLUSIONS: The complexity of the analysis of host genetic influences on HIV biology and pathogenesis calls for comprehensive motors of research on curated data. The tool developed here allows queries and supports validation of the rapidly growing body of host genomic information pertinent to HIV research.

05008-004 Mill-Picayune (Manteno Lake) Watershed Final Report

Manteno Lake is located 8 miles northwest of Earling, IA in Shelby County. The lake has been impaired with an overload of silt and nutrients. In October of 2007, land directly north of the lake will be coming out of CRP and back into agricultural production. The Shelby Soil and Water Conservation District, Shelby County Board of Supervisors and Shelby County Conservation Board feel strongly that treatment of this area is necessary prior to the CRP contract expiring. The placement and construction of three structures will reduce the amount of silt and nutrients affecting Manteno Lake. This project calls for the construction of three structures on crucial tributaries to the lake.

How siblings adjust sib-sib communication and begging signals to each other

Parents allocate food resources to their offspring in proportion to the intensity of begging behaviour. Begging encompasses several activities including vocalizations that should honestly signal need and jostling for the position in the nest where parents predictably deliver food items. Although siblings are known to adjust begging level to each other, the underlying mechanism remains unknown. We examined this issue in experimental two-chick broods of the barn owl, Tyto alba, a species in which siblings communicate vocally with each other in the prolonged absence of parents. The function of sib-sib vocal communication, so-called sibling negotiation, is to resolve conflicts over which individual will have priority of access to the next delivered indivisible food item. We found that when a nestling produced longer negotiation calls and stood closer to the nestbox entrance in the absence of parents, its sibling vocally negotiated at a lower rate. Additionally, when an individual produced more negotiation calls in the absence of parents, its sibling begged less intensely at the parent's return, with begging being the key factor that determined which nestling obtained a food item. We conclude that position in the nest and the duration of negotiation calls produced in the absence of parents influence the rate of producing negotiation calls, which in turn influences the rate at which siblings beg for food from their parents. Adjusting begging behaviour could therefore depend on complex sib-sib interactions taking place in the prolonged absence of parents.
