Stratification by smoking status reveals an association of CHRNA5-A3-B4 genotype with body mass index in never smokers.

We previously used a single nucleotide polymorphism (SNP) in the CHRNA5-A3-B4 gene cluster associated with heaviness of smoking within smokers to confirm the causal effect of smoking in reducing body mass index (BMI) in a Mendelian randomisation analysis. While seeking to extend these findings in a larger sample we found that this SNP is associated with 0.74% lower body mass index (BMI) per minor allele in current smokers (95% CI -0.97 to -0.51, P = 2.00 × 10(-10)), but also unexpectedly found that it was associated with 0.35% higher BMI in never smokers (95% CI +0.18 to +0.52, P = 6.38 × 10(-5)). An interaction test confirmed that these estimates differed from each other (P = 4.95 × 10(-13)). This difference in effects suggests the variant influences BMI both via pathways unrelated to smoking, and via the weight-reducing effects of smoking. It would therefore be essentially undetectable in an unstratified genome-wide association study of BMI, given the opposite association with BMI in never and current smokers. This demonstrates that novel associations may be obscured by hidden population sub-structure. Stratification on well-characterized environmental factors known to impact on health outcomes may therefore reveal novel genetic associations.

Prédiction des durées de séjour en réadaptation en fonction du status fonctionnel

Objectif : En Suisse, la réadaptation est financée en partie par l'assureur qui fixe préalablement à l'admission un nombre de jours (durée garantie) qu'il s'engage à rembourser. Lorsqu'une durée garantie est trop courte, une demande de prolongation est nécessaire, induisant des démarches administratives. Les objectifs de cette étude étaient a) d'étudier le lien entre durées garanties et caractéristiques du patient ; b) d'estimer les coûts liés aux demandes de prolongation ; c) d'évaluer l'impact de l'introduction d'un modèle d'attribution de durée garantie basé sur l'état fonctionnel du patient.¦Méthodes : Les corrélations entre état fonctionnel, durée effective et durée garantie ont été testées sur 208 séjours représentatifs. Des durées garanties fictives ont été calculées à partir de la médiane de durée de séjour de 2 335 patients, groupés selon leur niveau fonctionnel (score des activités de base de la vie quotidienne (BAVQ) 0-1 vs 2-4 vs 5-6), puis comparées aux durées de séjour effectives et garanties.¦Résultats : L'état fonctionnel du patient n'est pas corrélé à la durée garantie, et 69 % des séjours nécessitent au moins une demande de prolongation, représentant 2,6 équivalents temps plein en temps administratif projeté sur le canton. L'application du modèle proposé réduirait de 28 % les demandes de prolongation, et n'augmenterait que marginalement la proportion de jours garantis en surplus (11,2 % contre 6,5 % actuellement).¦Conclusion : L'utilisation systématique d'un modèle d'attribution de durées garanties basées sur l'état fonctionnel du patient permettrait de réduire sensiblement les coûts administratifs liés aux demandes de prolongation, sans entraîner de risque accru d'une augmentation de la durée de séjour.

Experimental and computational approaches to quantitative proteomics: status quo and outlook.

Proteomics has come a long way from the initial qualitative analysis of proteins present in a given sample at a given time ("cataloguing") to large-scale characterization of proteomes, their interactions and dynamic behavior. Originally enabled by breakthroughs in protein separation and visualization (by two-dimensional gels) and protein identification (by mass spectrometry), the discipline now encompasses a large body of protein and peptide separation, labeling, detection and sequencing tools supported by computational data processing. The decisive mass spectrometric developments and most recent instrumentation news are briefly mentioned accompanied by a short review of gel and chromatographic techniques for protein/peptide separation, depletion and enrichment. Special emphasis is placed on quantification techniques: gel-based, and label-free techniques are briefly discussed whereas stable-isotope coding and internal peptide standards are extensively reviewed. Another special chapter is dedicated to software and computing tools for proteomic data processing and validation. A short assessment of the status quo and recommendations for future developments round up this journey through quantitative proteomics.

Intravenous lacosamide for treatment of status epilepticus.

Objectives -  Treatment of established status epilepticus (SE) requires immediate intravenous anticonvulsant therapy. Currently used first-line drugs may cause potentially hazardous side effects. We aimed to assess the efficacy and safety of intravenous lacosamide (LCM) in SE after failure of standard treatment. Methods -  We retrospectively analyzed 39 patients (21 women, 18 men, median age 62 years) from the hospital databases of five neurological departments in Germany, Austria and Switzerland between September 2008 and January 2010 who were admitted in SE and received at least one dose of intravenous LCM. Results -  Types of SE were generalized convulsive (n = 6), complex partial (n = 17) and simple partial (n = 16). LCM was administered after failure of benzodiazepins or other standard drugs in all but one case. Median bolus dose of LCM was 400 mg (range 200-400 mg), which was administered at 40-80 mg/min in those patients where infusion rate was documented. SE stopped after LCM in 17 patients, while 22 patients needed further anticonvulsant treatment. The success rate in patients receiving LCM as first or second drug was 3/5, as third drug 11/19, and as fourth or later drug 3/15. In five subjects, SE could not be terminated at all. No serious adverse events attributed to LCM were documented. Conclusions -  Intravenous LCM may be an alternative treatment for established SE after failure of standard therapy, or when standard agents are considered unsuitable.

Ictal cerebral positron emission tomography (PET) in focal status epilepticus.

The diagnosis of focal status epilepticus (SE) can be challenging, particularly when clinical manifestations leave doubts about its nature, and electroencephalography (EEG) is not conclusive. This work addresses the utility of ictal (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) in focal SE, which was performed in eight patients in whom SE was finally diagnosed. Clinical, MRI and EEG data were reviewed. (18)F-FDG-PET proved useful: (1) to establish the diagnosis of focal SE, when clinical elements were equivocal or the EEG did not show clear-cut epileptiform abnormalities; (2) to delineate the epileptogenic area in view of possible resective surgery; and (3) when clinical features, MRI and EEG were incongruent regarding the origin of SE. We suggest that ictal (18)F-FDG-PET may represent a valuable diagnostic tool in selected patients with focal SE or frequent focal seizures.

Midwest Regional Rail Passenger Initiative Status Report December 2006

This report is submitted as required per Code of Iowa section 327J.3(5), "The director shall report annually to the general assembly concerning the development and operation of the midwest regional rail system and the state's passenger rail service." The Midwest Regional Rail Initiative (MWRRI) is a nine-state effort to develop an implementation plan for a 3,000-mile, high-speed rail system hubbed in Chicago. Studies done since 1996 have concluded that such a regional system, including a line from Chicago to Omaha through Davenport, Iowa City and Des Moines, is viable. Most of the system would be upgraded to allow 110 mile-per-hour service. Some low volume lines, including the Iowa portions, would be upgraded for 79 mile-per-hour service. The nine-state coalition released an updated 2004 executive report for the system. As reported, the updated cost estimate for the Chicago to Omaha corridor, which includes a branch to Quincy, Ill., is $638 million for infrastructure and $167 million for rolling stock. These costs are higher than first estimated in 1998 and are given in 2002 dollars, (not adjusted for the cost of inflation). Operating subsidies would be required during an extended start-up phase. The allocation of these subsidy costs among the various states has not been determined, and is still a subject for analysis and negotiation. Little progress on implementation is expected unless a federal funding package is passed for passenger rail initiatives. Continued congressional discussion on policy directions relative to Amtrak clouds the issue of passenger rail funding. However, Congress is expected to address passenger rail issues and funding in 2007. Participation of the Iowa Department of Transportation in the MWRRI is authorized under Iowa Code section 327J.3.

Estudio clínico y mutacional de una cohorte de pacientes con mutación en el gen hnf1b

HNF1B (Hepatocyte Nuclear Factor 1-B localizado en el cromosoma 17q21.3) es un factor de transcripción con un papel fundamental en los primeros estadios del desarrollo y en la organogénesis de diferentes tejidos como el renal, hepático, pancreático o genital. Las mutaciones de este gen se heredan con un patrón autosómico dominante. A nivel renal acostumbran a haber alteraciones morfológicas y grados variables de afectación tubular. A nivel extrarenal se ha relacionado con la diabetes tipo MODY, malformaciones genitales o alteraciones hepáticas. La gran variabilidad de formas de presentación hace que la sospecha clínica resulte en muchas ocasiones dificultosa. En el presente estudio, se realiza una descripción clínica y génètica de los pacientes identificados en nuestro centro con mutación en el gen HNF1b. Observamos, en consonancia con lo descrito en la literatura, una gran variabilidad interfamiliar y intrafamiliar, así como una ausencia de relación fenotipo-genotipo en cuanto la forma de presentación o evolución de la enfermedad. Se recomienda el estudio de HNF1b en pacientes pediátricos o adultos con patología estructural renal, especialmente si se asocia a diabetes tipo MODY, malformaciones genitales, hipomagnesemia, hiperuricemia o antecedentes familiares de nefropatía.

Current status of the whitefly Aleurodicus dispersus as an invasive pest in the CapeVerte Islands

In the last three decades, the spiralling whitefly (Aleurodicus dispersus) has become an important international pest. The movement of plants and parts of plants (such as fruits) in international trade and tourism, and by natural dispersal, has favoured its introduction to new areas. In common with others whiteflies of economic importance, the immature and adult stages cause direct feeding damage by piercing and sucking of sap from foliage, and indirect damage following the accumulation all over host plants of honeydew and waxy flocculent material produced by the insects. Spiralling whitefly is a pest of tropical and subtropical crops, and highly polyphagous. Up to the 1970s, it had been recorded on 44 genera of plants, belonging to 26 botanical families (Mound & Halsey, 1978). This situation changed with the dispersal of the pest to new areas. Nowadays, the spiralling whitefly is one of the major pest of vegetable, ornamental and fruit crops around the globe (Lambkin, 1999). Important host crops include: banana (Musa sapientum), Citrus spp., coconut (Cocos nocifera), eggplant (Solanum melanogena), guava (Psidium guajava), Hibiscus rosa sinensis, Indian almond (Terminalia catappa), papya (Carica papaya), Rosa sp. and tomato (Lycopersicon esculentum) (Saminathan & Jayaraj, 2001). Spiralling whitefly has its origin in the tropical Americas, including Brazil. Although the pest has been recorded only once in Brasil, in the 1920s in the state of Bahia (Bondar, 1923), it now has official quarantine status because of its economic importance. In the Cape Verte Islands, on the West African coast, the pest was initially introduced in the first half of 2000; it has since become established, reaching urban, natural and agricultural areas of the islands that constitute the archipelago. Since then, the pest has been causing damage to many native plants, ornamentals and cultivated food crops (Anon., 2001; Monteiro, 2004). The present study was done in order to produce an inventory of the most common host plants of spiralling whitefly in this new habitat.
