Überinfusion von Verbrennungsopfern: häufig und schädlich [Over infusion in burn victims: frequent and injurious]

Major burns are characterized by an initial capillary leak, which requires fluid resuscitation for hemodynamic stabilization. While under resuscitation was the major cause of death until the 1980s, over resuscitation has become an important source of complications, including abdominal compartment syndrome, escharosis, impaired gas exchange with prolonged mechanical ventilation and hospital stay. Fluid over infusion started in the 1990s with an increasing proportion of the fluid delivered within the first 24 h being well above the 4 ml/kg/% burn surface area (BSA) according to the Parkland formula. The first alerts were published in the form of case reports of increased mortality due to abdominal compartment syndrome and respiratory failure. This paper analyses the causes of this fluid over infusion and the ways to prevent it, which include rationing prehospital fluid delivery, avoiding early administration of colloids and prevention by permissive hypovolemia.

A Study on the Use of Fabric to Retard Reflective Cracking Over Widened Joints, MLR-88-4, 1992

Reflective cracking of asphalt resurfacing has been a concern for a long time. Years ago wire mesh was used to control widening cracks. More recently it has been fabrics or fiberglass. In 1986, part of the proposed fabric was deleted from projects in different parts of Iowa with various histories and designs. These projects were monitored in 1988, 1989, 1990 and 1992 with only the thin (3 inch) overlays on newly widened pavements showing a significantly greater percentage of cracks in the areas where the fabric was deleted.

Persistent association of nailfold capillaroscopy changes and skin involvement over thirty-six months with duration of untreated disease in patients with juvenile dermatomyositis.

OBJECTIVE: To determine the association of changes on nailfold capillaroscopy with clinical findings and genotype in children with juvenile dermatomyositis (DM), in order to identify potential differences in disease course over 36 months. METHODS: At diagnosis of juvenile DM in 61 children prior to the initiation of treatment, tumor necrosis factor alpha (TNFalpha) -308 allele and DQA1*0501 status was determined, juvenile DM Disease Activity Scores (DAS) were obtained, and nailfold capillaroscopy was performed. The disease course was monitored for 36 months. Variations within and between patients were assessed by regression analysis. RESULTS: At diagnosis, shorter duration of untreated disease (P = 0.05) and a lower juvenile DM skin DAS (P = 0.035) were associated with a unicyclic disease course. Over 36 months, end-row loop (ERL) regeneration was associated with lower skin DAS (P < 0.001) but not muscle DAS (P = 0.98); ERL regeneration and decreased bushy loops were associated with a shorter duration of untreated disease (P = 0.04 for both). At 36 months, increased ERL regeneration (P = 0.007) and improvement of skin DAS (P < 0.001) and muscle DAS (P = 0.025) were associated with a unicyclic disease course. CONCLUSION: Early treatment of juvenile DM may lead to a unicyclic disease course. The non-unicyclic disease course usually involves continuing skin manifestations with persistent nailfold capillaroscopy changes. The correlation of nailfold capillaroscopy results with cutaneous but not with musculoskeletal signs of juvenile DM over a 36-month period suggests that the cutaneous and muscle vasculopathies have different pathophysiologic mechanisms. These findings indicate that efforts to identify the optimal treatment of cutaneous features in juvenile DM require greater attention.

Copy number variation modifies expression profiles over developmental time

Abstract : A preliminary understanding of the phenotypic effect of copy number variation (CNV) of DNA segments is emerging. These rearrangements were shown to influence, in a somewhat dose-dependent manner, the expression of genes mapping within them. They were also shown to modify the expression of genes located on their Hanks, sometimes at great distance. Here, we demonstrate by monitoring these effects at multiple life stages, that these controls over expression are effective throughout mouse development. Similarly, we observe that the more specific spatial expression patterns of CNV genes are maintained through life. However, 'we find that some brain- expressed genes mapping within CNVS appear to be under compensatory loops only at specific time-points, indicating that the effect of CNVS on these genes is modulated during development. Notably, we also observe that CNV genes are significantly enriched within transcripts that show variable time-course expression between strains. Thus, modifying the copy number of a gene may potentially alter not only its expression level, but its timing of expression as well. Résume : Nous commençons à comprendre les effets phénotypiques liés aux séquences d'ADN qui changent de nombre de copies d'un individu a l'autre. Des travaux précédents ont montré que ces variante de nombre de copies (CNVS) avaient une influence sur l'expression non seulement des gènes se trouvant dans le réarrangement, mais aussi sur ceux se trouvant à une certaine distance. Le présent travail étudie ces effets à différents stades du développement de la souris allant d'un embryon de deux semaines à la souris adulte. Nous avons observé que certains gènes exprimés dans le cerveau semblent soumis à un contrôle plus strict a certaines étapes du développement suggèrent que l'effet des CNVs est modulé différemment au cours de la vie. Notre travail sur trois souches différentes de souris a permis de montrer que les gènes ayant un profil d'expression différent dans le temps entre souches sont enrichis en gènes se trouvant dans des CNVs. Ceci nous amène à penser que les CNVs ont, non seulement une influence sur le niveau d'expression des gènes, mais aussi sur les moments durant lesquels ils seront exprimés. Résumé pour un large public : De nombreuses maladies sont dues soit a un gain (on parle alors de duplication) soit à une perte de matériel génétique (il s'agit dune délétion). Bien que les recherches visant à identifier les mécanismes moléculaires liés à ces réarrangements de notre génome progressent continuellement, la plupart des causes des maladies génétiques restent à élucider. Certaines parties de notre génome sont présentes en un nombre de copies qui diffère d'un individu à l'autre sans pour autant provoquer une ou des maladies. Ces segments d'ADN qui varient en nombre sont appelés Copy Number Variant (CNVs). Ils couvrent environ 12% de notre matériel génétique. Des études menées sur différents modèles animaux ont montré que les CNVs avaient une influence aussi bien sur les gènes qui sont a l'intérieur des CNVs que sur ceux qui sont dans leur voisinage. Ce travail étudie l'effet des CNVs à travers différents stades du développement de la souris. Nous avons démontré que les segments d'ADN qui varient en nombre de copies ont des effets variables selon le stade auxquels ils sont mesurés. Ainsi, les CNVs ont non seulement un impact sur l'expression des gènes présents dans ces régions et dans leur voisinage, mais influencent également leurs profils d'expression au cours du temps.

GDP and life expectancy in Italy and Spain over the long-run (1861-2008): insights from a timeseries approach

The article presents and discusses long-run series of per capita GDP and life expectancy for Italy and Spain (1861-2008). After refining the available estimates in order to make them comparable and with the avail of the most up-to-date researches, the main changes in the international economy and in technological and sociobiological regimes are used as analytical frameworks to re-assess the performances of the two countries; then structural breaks are searched for and Granger causality between the two variables is investigated. The long-run convergence notwithstanding, significant cyclical differences between the two countries can be detected: Spain began to modernize later in GDP, with higher volatility in life expectancy until recent decades; by contrast, Italy showed a more stable pattern of life expectancy, following early breaks in per capita GDP, but also a negative GDP break in the last decades. Our series confirm that, whereas at the early stages of development differences in GDP tend to mirror those in life expectancy, this is no longer true at later stages of development, when, if any, there seems to be a negative correlation between GDP and life expectancy: this finding is in line with the thesis of a non-monotonic relation between life expectancy and GDP and is supported by tests of Granger causality.

La actividad productiva de la fábrica de harinas “La Montserrat” (Girona) en el año agrícola de 1903-1904 = The Production Activities at the Company Harinera “La Montserrat” (Girona) over the Agricultural Year 1903-1904

Harinera La Montserrat, S.A, a company involved in the manufacturing and trading of cereals and flour, was founded in Girona in 1898 by José Ensesa y Cía., Sociedad en Comandita. With the objective to determine how the product activity of this business was structured, we have studied in detail the operations that were carried out over the agricultural year 1903-1904. We have focused on three main aspects. Firstly, the purchasing of wheat (origin, transportation, prices); secondly, the production of flour (using internal and external wheat, profits); and thirdly, its distribution (customers, destination). Finally, we have analyzed the profit and loos account for this period in order to find out if this business was profitable

Surréanimation liquidienne pré et intrahospitatière des patients brûlés: fréquente et néfaste [Pre- and intra-hospital over-resuscitation in burns: frequent and deleterious].

Major burns are characterized by an initial capillary leak which requires fluid resuscitation for hemodynamic stabilisation. While under-resuscitation was the major cause of death until the 80ies, over-resuscitation has become an important source of complications: abdominal compartment syndrome, escharotomies, impaired gas exchange and prolonged mechanical ventilation and hospital stay. The fluid creep started in the 90ies with an increasing proportion of the first 24 hours' fluid delivery above the 4 ml/kg/% BSA Parkland prediction. The first alerts were published under the form of case reports of increased mortality due to abdominal compartment syndrome and respiratory failure. The paper analyses the causes of this fluid creep, and the ways to prevent it, which includes rationing prehospital fluid delivery, avoiding early colloids and permissive hypovolemia.

Long-distance wolf recolonization of France and Switzerland inferred from non-invasive genetic sampling over a period of 10 years

In the early 1900s, the wolf (Canis lupus) was extirpated from France and Switzerland. There is growing evidence that the species is presently recolonizing these countries in the western Alps. By sequencing the mitochondrial DNA (mtDNA) control region of various samples mainly collected in the field (scats, hairs, regurgitates, blood or tissue; n = 292), we could (1) develop a non-invasive method enabling the unambiguous attribution of these samples to wolf, fox (Vulpes vulpes) or dog (Canis familiaris), among others; (2) demonstrate that Italian, French and Swiss wolves share the same mtDNA haplotype, a haplotype that has never been found in any other wolf population world-wide. Combined together, field and genetic data collected over 10 years corroborate the scenario of a natural expansion of wolves from the Italian source population. Furthermore, such a genetic approach is of conservation significance, since it has important consequences for management decisions. This first long-term report using non-invasive sampling demonstrates that long-distance dispersers are common, supporting the hypothesis that individuals may often attempt to colonize far from their native pack, even in the absence of suitable corridors across habitats characterized by intense human activities.
