Inpatient diabetes care in a Swiss multi-site hospital: is there room for improvement?

Background and objective: Optimal care of diabetic patients (DPs) decreases the risk of complications. Close blood glucose monitoring can improve patient outcomes and shorten hospital stay. The objective of this pilot study was to evaluate the treatment of hospitalized DPs according to the current standards, including their diabetic treatment and drugs to prevent diabetes related complications [=guardian drugs: angiotensin converting enzyme inhibitors (ACEI) or Angiotensin II Receptor Blockers (ARB), antiplatelet drugs, statins]. Guidelines of the American Diabetes Association (ADA) [1] were used as reference as they were the most recent and exhaustive for hospital care. Design: Observational pilot study: analysis of the medical records of all DPs seen by the clinical pharmacists during medical rounds in different hospital units. An assessment was made by assigning points for fulfilling the different criteria according to ADA and then by dividing the total by the maximum achievable points (scale 0-1; 1 = all criteria fulfilled). Setting: Different Internal Medicine and Geriatric Units of the (multi-site) Ho^pital du Valais. Main outcome measures: - Completeness of diabetes-related information: type of diabetes, medical history, weight, albuminuria status, renal function, blood pressure, (recent) lipid profile. - Management of blood glucose: Hb1Ac, glycemic control, plan for treating hyper-/hypoglycaemia. - Presence of guardian drugs if indicated. Results: Medical records of 42 patients in 10 different units were analysed (18 women, 24 men, mean age 75.4 ± 11 years). 41 had type 2 diabetes. - Completeness of diabetes-related information: 0.8 ± 0.1. Information often missing: insulin-dependence (43%) and lipid profile (86%). - Management of blood glucose: 0.5 ± 0.2. 15 patients had suboptimal glycemic balance (target glycaemia 7.2-11.2 mmol/ l, with values[11.2 or\3.8 mmol/l, or Hb1Ac[7%), 10 patients had a deregulated balance (more than 10 values[11.2 mmol/l or \3.8 mmol/l and even values[15 mmol/l). - Presence of guardian drugs if indicated: ACEI/ARB: 19 of 23 patients (82.6%), statin: 16 of 40 patients (40%), antiplatelet drug: 16 of 39 patients (41%). Conclusions: Blood glucose control was insufficient in many DPs and prescription of statins and antiplatelet drugs was often missing. If confirmed by a larger study, these two points need to be optimised. As it is not always possible and appropriate to make those changes during hospital stay, a further project should assess and optimise diabetes care across both inpatient and outpatient settings.

Donor-site morbidity of the sensate extended lateral arm flap.

The free extended lateral arm flap (ELAF) has gained increasing popularity thank to its slimness and versatility, longer neurovascular pedicle, and greater flap size when compared with the original flap design. The aim of this study was to assess the donor-site morbidity associated with this extended procedure. A retrospective study of 25 consecutive patients analyzing postoperative complications using a visual analogue scale questionnaire revealed high patients satisfaction and negligible donor-site morbidity of the ELAF. Scar visibility was the commonest negative outcome. Impaired mobility of the elbow had the highest correlation with patient dissatisfaction. Sensory deficits or paresthetic disorders did not affect patient satisfaction. The extension of the lateral arm flap and positioning over the lateral humeral epicondyle is a safe and well-accepted procedure with minimal donor-site morbidity. To optimize outcomes, a maximal flap width of 6 or 7 cm and intensive postoperative mobilization therapy is advisable.

Habitat selection by grey mullets (Osteichthyes: Mugilidae) in Mediterranean estuaries: the role of salinity.

A stratified study of microhabitat use by grey mullet on the island of Minorca (Balearic archipelago, western Mediterranean) showed that the distribution of all the species was dramatically affected by salinity. Sites with a salinity level under 15 were positively selected in spring and summer by those species whose growth performance was the best in oligomesohaline water (Liza ramado and Mugil cephalus) but also by a species whose growth was not affected by salinity (Chelon labrosus). Liza aurata concentrated in polyhaline and euhaline sites, where growth was improved, a pattern also exhibited by Liza saliens. Both species avoided fresh water sites all year round. As a consequence, community structure was correlated with salinity. The above reported electivity patterns often disappeared in autumn, when most grey mullets migrate off-shore.

Fine-Tuning Translation Kinetics Selection as the Driving Force of Codon Usage Bias in the Hepatitis A Virus Capsid

Hepatitis A virus (HAV), the prototype of genus Hepatovirus, has several unique biological characteristics that distinguish it from other members of the Picornaviridae family. Among these, the need for an intact eIF4G factor for the initiation of translation results in an inability to shut down host protein synthesis by a mechanism similar to that of other picornaviruses. Consequently, HAV must inefficiently compete for the cellular translational machinery and this may explain its poor growth in cell culture. In this context of virus/cell competition, HAV has strategically adopted a naturally highly deoptimized codon usage with respect to that of its cellular host. With the aim to optimize its codon usage the virus was adapted to propagate in cells with impaired protein synthesis, in order to make tRNA pools more available for the virus. A significant loss of fitness was the immediate response to the adaptation process that was, however, later on recovered and more associated to a re-deoptimization rather than to an optimization of the codon usage specifically in the capsid coding region. These results exclude translation selection and instead suggest fine-tuning translation kinetics selection as the underlying mechanism of the codon usage bias in this specific genome region. Additionally, the results provide clear evidence of the Red Queen dynamics of evolution since the virus has very much evolved to re-adapt its codon usage to the environmental cellular changing conditions in order to recover the original fitness.

Postglacial recolonization at a snail's pace (Trochulus villosus): confronting competing refugia hypotheses using model selection.

The localization of Last Glacial Maximum (LGM) refugia is crucial information to understand a species' history and predict its reaction to future climate changes. However, many phylogeographical studies often lack sampling designs intensive enough to precisely localize these refugia. The hairy land snail Trochulus villosus has a small range centred on Switzerland, which could be intensively covered by sampling 455 individuals from 52 populations. Based on mitochondrial DNA sequences (COI and 16S), we identified two divergent lineages with distinct geographical distributions. Bayesian skyline plots suggested that both lineages expanded at the end of the LGM. To find where the origin populations were located, we applied the principles of ancestral character reconstruction and identified a candidate refugium for each mtDNA lineage: the French Jura and Central Switzerland, both ice-free during the LGM. Additional refugia, however, could not be excluded, as suggested by the microsatellite analysis of a population subset. Modelling the LGM niche of T. villosus, we showed that suitable climatic conditions were expected in the inferred refugia, but potentially also in the nunataks of the alpine ice shield. In a model selection approach, we compared several alternative recolonization scenarios by estimating the Akaike information criterion for their respective maximum-likelihood migration rates. The 'two refugia' scenario received by far the best support given the distribution of genetic diversity in T. villosus populations. Provided that fine-scale sampling designs and various analytical approaches are combined, it is possible to refine our necessary understanding of species responses to environmental changes.

Site Development and Facility Expansion Regulatory Assistance Program, 2001

The Iowa Department of Economic Development (IDED) helps businesses expand or locate all or part of their business in Iowa. It just makes sense for companies engaged in advanced manufacturing, biosciences and information solutions/financial services to look at Iowa and IDED helps to ensure their economic development timelines are met. Iowa is nationally recognized as an innovator in helping businesses by meeting their development needs in a timely and effective manner. IDED networks with Regulatory Assistance Coordinators in agencies across state government to reduce response time to businesses. This agency coordination helps to ensure that regulatory and compliance questions, or other needs associated with project site development and facility expansion are serviced quickly. We have listed information below about some of the more common regulatory requirements related to site development and expansion.

Recherche de l'iridium à la limite Permien-Trias du site de Meishan, Changhsing (R. P. Chine).

La forte teneur en elements siderophiles des sediments de la limite Cretace-Tertiaire suggere que les principaJes disparitions d'especes ont ete provoquees par des catastrophes cosmiques. Cette hypothese pourrait etre confirmee par la decouverte d'une anomaJie similaire it la limite Permien-Trias, caracterisee par la plus grave crise biologique du Phanerozoique. L'etude du site de Meishan, en Republique populaire de Chine, n'apporte aucune confirmation de ce scenario. Aucune trace d'iridium, Ie meilleur traceur de la matiere extraterrestre, n'a ete trouvee dans les 18 echantillons preleves au voisinage de la transition Permien-Trias. Toute relation entre la crise biologique du Permien-Trias et une catastrophe cosmique doit donc, pour l'instant, etre consideree comme hypothetique. The presence of siderophile-enriched material at the Cretaceous-Tertiary boundary suggests that the major extinctions of living species could result from cosmic catastrophes. The finding of the same kind of material at the Permian-Triassic boundary would be important to confirm the influence of cosmic phenomena on extinctions. The study of the M eishan section, in China, does not provide any support to this view. Iridium, the best tracer of cosmic material, has not been detected in any of the 18 samples collected around the boundary. A relation between the Permian-Triassic extinction and a cosmic collision therefore remains hypothetical.

Patterns of positive selection in seven ant genomes.

The evolution of ants is marked by remarkable adaptations that allowed the development of very complex social systems. To identify how ant-specific adaptations are associated with patterns of molecular evolution, we searched for signs of positive selection on amino-acid changes in proteins. We identified 24 functional categories of genes which were enriched for positively selected genes in the ant lineage. We also reanalyzed genome-wide data sets in bees and flies with the same methodology to check whether positive selection was specific to ants or also present in other insects. Notably, genes implicated in immunity were enriched for positively selected genes in the three lineages, ruling out the hypothesis that the evolution of hygienic behaviors in social insects caused a major relaxation of selective pressure on immune genes. Our scan also indicated that genes implicated in neurogenesis and olfaction started to undergo increased positive selection before the evolution of sociality in Hymenoptera. Finally, the comparison between these three lineages allowed us to pinpoint molecular evolution patterns that were specific to the ant lineage. In particular, there was ant-specific recurrent positive selection on genes with mitochondrial functions, suggesting that mitochondrial activity was improved during the evolution of this lineage. This might have been an important step toward the evolution of extreme lifespan that is a hallmark of ants.

Startegy selection during exploratory behavior: sex differences, uncertainty and risk managment

This study deals with the psychological processes underlying the selection of appropriate strategy during exploratory behavior. A new device was used to assess sexual dimorphisms in spatial abilities that do not depend on spatial rotation, map reading or directional vector extraction capacities. Moreover, it makes it possible to investigate exploratory behavior as a specific response to novelty that trades off risk and reward. Risk management under uncertainty was assessed through both spontaneous searching strategies and signal detection capacities. The results of exploratory behavior, detection capacities, and decision-making strategies seem to indicate that women's exploratory behavior is based on risk-reducing behavior while men behavior does not appear to be influenced by this variable. This difference was interpreted as a difference in information processing modifying beliefs concerning the likelihood of uncertain events, and therefore influencing risk evaluation.

Ubiquitination of the Epstein-Barr virus-encoded latent membrane protein 1 depends on the integrity of the TRAF binding site.

The latent membrane protein 1 (LMP1) encoded by the Epstein-Barr virus functions as a constitutively activated receptor of the tumor necrosis factor receptor family. LMP1 is a short-lived protein that is ubiquitinated and degraded by the proteasome. We have previously shown that LMP1 recruits the adapter protein tumor necrosis factor receptor-associated factor 3 (TRAF3) to lipid rafts. To test if TRAFs are involved in LMP1's ubiquitination, we have mutated the LMP1 CTAR1 site that has been identified as a TRAF binding site. We show that the CTAR1 mutant (CTAR1(-)) is expressed after transfection at a similar level to wild-type LMP1, and behaves as wild-type LMP1 with respect to membrane localization. However, CTAR1(-) does not bind TRAF3. We demonstrate that ubiquitination of CTAR1(-) is significantly reduced when compared to wild-type LMP1. In addition, the expression of wild-type LMP1 induces the ubiquitination, an effect that is significantly reduced when the CTAR1(-) is expressed. Taken together, our results suggest that TRAF proteins are involved in the ubiquitination of LMP1, and that their binding to LMP1 may facilitate their own ubiquitination.
