Uses of also in oral semi-informal German

In recent grammars and dictionaries also (`therefore, so, well¿) continues to be preferably presented as an adverb with a conclusive-consecutive connective function that essentially corresponds to its use in formal written German. Its function as a modal particle is documented, however, since the beginnings of what is known as Partikelforschung, though not all its uses have been systematically investigated contrasting oral and written German, either in mode or concept. In this article we analyse the uses of also in semi-informal oral interactions on the basis of empirical data (from a subsample of the VARCOM corpus). Specifically, we will analyse the presence and frequency of also at the beginning of a sentence or sequence, the functions it serves as a logical-semantic connector or discourse and interaction marker and the interrelations between these functions, in order to contrast these results with the description of also provided by current reference works.

Dimensió educativa de l'aprenentatge del discurs oral en una llengua segona o en una llengua estrangera

En un segle hem passat de considerar l'ensenyament de llengues estrangeres com una activitat marginal sense cap dimensió educativa reconeguda a considerar-lo com una activitat que cada vegada té un paper més notable en els programes deis estudiants de secundaria i que reclama més atenció en els estudis superiors. Avui dia, no és pensable una formació superior sense una comprensió ben desenvolupada de l'anglés com a llengua vehicular d'informació deis camps de coneixement més variats. Algunes formacions de caracter superior requereixen a més a més altres habilitats lingüístiques com ara parlar i escriure. La situació dominant de l'anglés, pero, no ens ha de fer oblidar que també són necessaries altres llengues si els professionals s'han de moure en un mercat de treball únic en una Europa extremadament plurilingue: i així es veura que per exemple és probablement inadequat de formar graduats i llicenciats amb perfils que els faci integrables en els sectors comercials de la indústria o les finances sense dotar-los d'uns coneixements satisfactoris de dues llengues estrangeres (a la Universitat de Barcelona, els estudiants que podrien integrar aquest grup representen actualment més d'un 20 per cent del total de l'alumnat).

Incorporation and washout of n-3 PUFA after high dose intravenous and oral supplementation in healthy volunteers.

BACKGROUND & AIMS: Although the physiological effects of n-3 polyunsaturated fatty acids (n-3PUFA) are generally thought to require several weeks of exposure to allow their incorporation into plasma membranes, intravenous (IV) n-3PUFA attenuate the cardiovascular and neuroendocrine response to stress within 3 h. Whether oral n-3 PUFA exert similar early effects remains unknown. OBJECTIVE: To assess whether acute IV or short term oral n-3PUFA administration reproduces the metabolic effects of long term oral supplements during exercise, and how it relates to their incorporation into platelets and red blood cells (RBC) membranes. DESIGN: Prospective single center open label study in 8 healthy subjects receiving a 3-h infusion of 0.6 g/kg body weight n-3PUFA emulsion, followed one week later by an oral administration of 0.6 g/kg over 3 consecutive days. Maximal power output (cycling exercise), maximal heart rate (HR), blood lactate at exhaustion, and platelet function were measured at baseline and after IV or 3-day oral supplementation; platelet and RBC membrane composition were assessed until 15 days after n-3PUFA administration. RESULTS: Both IV and oral n-3PUFA significantly decreased maximal HR (-6% and -5%), maximal power output (-10%) and peak blood lactate (-47% and -52%) Platelet function tests were unchanged. The EPA and DHA membrane contents of RBC and platelets increased significantly, but only to 1.7-1.9% of fatty acid content. CONCLUSION: The cardiovascular and metabolic effects of n-3 PUFA during exercise occur already within 1-3 days of exposure, and may be unrelated to changes in membranes composition. Effects occur within hours of administration and are unrelated to lipid membrane composition. Trial registered at clinicaltrials.gov as NCT00516178.

Caspofungin for prevention of intra-abdominal candidiasis in high-risk surgical patients.

PURPOSE: Thirty to forty percent of patients with recurrent gastrointestinal perforation/anastomotic leakage or acute necrotizing pancreatitis develop intra-abdominal invasive candidiasis (IC). A corrected Candida colonization index (CCI) > or =0.4 is a powerful predictor of IC. Fluconazole prevents intra-abdominal IC in this setting, but azole-resistant Candida species are emerging. The aim of this study was to explore the efficacy and safety of caspofungin for prevention of intra-abdominal IC in high-risk surgical patients. METHODS: Prospective non-comparative single-center study in consecutive adult surgical patients with recurrent gastrointestinal perforation/anastomotic leakage or acute necrotizing pancreatitis. Preventive caspofungin therapy (70 mg, then 50 mg/day) was given until resolution of the surgical condition. Candida colonization index and CCI, occurrence of intra-abdominal IC and adverse events were monitored. RESULTS: Nineteen patients were studied: 16 (84%) had recurrent gastrointestinal perforation/anastomotic leakage and 3 (16%) acute necrotizing pancreatitis. The median duration of preventive caspofungin therapy was 16 days (range 4-46). The colonization index decreased significantly during study therapy, and the CCI remained <0.4 in all patients. Caspofungin was successful for prevention of intra-abdominal IC in 18/19 patients (95%, 1 breakthrough IC 5 days after inclusion). No drug-related adverse event requiring caspofungin discontinuation occurred. CONCLUSION: Caspofungin may be efficacious and safe for prevention of intra-abdominal candidiasis in high-risk surgical patients. This needs to be further investigated in randomized trials.

Decreased thermogenic response to an oral glucose load in older subjects.

The thermogenic response to a 100 g oral glucose load was studied by indirect calorimetry in 13 older persons (age range, 38-68 years) and compared with that of 16 young matched controls of similar body weight (age range, 19-30 years). The glucose-induced thermogenesis measured over 180 min and expressed as a per cent of the energy content of the glucose load was found to be reduced in the older subjects, i.e., 5.8 +/- 0.3 per cent vs 8.6 +/- 0.7 per cent, P less than 0.002). This was also accompanied by a significant decrease in the glucose oxidation rate when averaged over the same three-hour period following the glucose load, i.e., 153 mg/min vs 213 mg/min in the control subjects (P less than 0.001) despite a similar time course of glycemia. This study suggests that the thermogenic response to an oral glucose load is blunted in older people, and this may represent an additional factor that contributes to the decreased energy requirement with age and therefore to the increased propensity to obesity if energy intake is not adjusted.

La prótesis bucal como causante del carcinoma espinocelular oral

La aparición de cáncer bucal está vinculada a múltiples factores de riesgo. En este artículo queremos exponer como uno de ellos la úlcera crónica producida por las prótesis dentales removibles o fijas.

La cresta alveolar atrófica en implantología oral

Los implantes dentales endoóseos constituyen una alternativa terapéutica ideal en pacienfes parcial o totalmente edéntulos; sin embargo, en ocasiones, la atrofia ósea generalizada o localizada contraindica el tratamiento, siendo necesario realizar un aumento de cresta alveolar que permita, bien simultáneamente o deforma diferida, la adecuada rehabilitación implantológica. En el presente trabajo, hacemos una revisión de las distintas técnicas y materiales utilizados actualmente en implantología, para mejorar las condiciones de recepción de los implantes, en presencia de defectos óseos.

Oral tongue squamous cell carcinoma (OTSCC): alcohol and tobacco consumption versus non-consumption. A study in a Portuguese population

There has been an increase in the incidence of carcinoma of the tongue, particularly among alcohol and tobacco non-users. However, the number of studies that would allow a better understanding of etiological factors and clinical features, particularly in the Portuguese population, is very limited. This study was based on patients with squamous cell carcinoma of the anterior two thirds of the tongue that were treated at the Department of Head and Neck Surgery of the ¿Instituto Portugues de Oncologia de Lisboa - Francisco Gentil" IPOLFG) in Lisbon, Portugal, between January 1, 2001 and December 31, 2009. The patients were divided in alcohol and tobacco users and non-users in order to evaluate the differences between these 2 groups based on gender, age, tumor location, denture use, and tumor size, metastasis and stage. Of the 354 cases, 208 were users and 146 were non-users. The main location in both groups was the lateral border of the tongue. Denture use showed no significant effect in both study groups. It was possible to conclude that patients who did not drink or smoke were older and presented with smaller tumor size, lower incidence of ganglion metastasis and lower tumor stage compared with alcohol and tobacco users.

Estomatitis protésica: puesta al dia

La estomatitis protésica es una inflamación crónica de la mucosa oral debida al contacto con una prótesis extraible. Es un proceso difícil de controlar en los pacientes portadores de este tipo de prótesis. La patología involucra diferentes factores predisponentes, y el más importante de ellos es la presencia de Candida. En el presente artículo se describe el manejo del paciente y las dificultades de los tratamientos actuales para eliminar de las prótesis y de la mucosa oral los residuos fúngicos. Se concluye que los hábitos de higiene oral y personal en pacientes portadores de prótesis extraible son los métodos principales para evitar la aparición de la patología. Una vez instaurada, podemos controlar al paciente con medidas higiénicas y agentes antifúngicos, pero debemos ser conscientes de las limitaciones terapéuticas ante los depósitos de Candidade las prótesis. En algunos casos puede estar indicada la sustitución de la prótesis por una nueva.

Technological, biopharmaceutical and pharmacokinetic advances: new formulations of application on the skin and oral mucosa

Currently a growing interest to improve the pharmacological therapy exists, not only by the production and the appearance of new drugs, but guaranteeing that the uses of those which already exist, become more effective. In fact, the conventional pharmaceutical formulations of different drugs present a few secondary effects due to oral administration. In order to avoid these undesired side effects, the purpose of current therapeutic is the development and research of formulations as an alternative to others routes of administration. Therefore, in spite of the undoubtedly complete parenteral absorption, the transdermal and transbuccal routes appear to be a rather attractive alternative to provide an efficient absorption. In this chapter a new technological, biopharmaceutical and pharmacokinetic approach of strategies for application on skin and buccal mucosa are reported. In the future new transdermal drug delivery systems will emerge to be more effective, equipped with an improved aesthetic appearance, better adherence and greater diffusion. But to reach these aims, it is necessary previous knowledge of histology and physiology of skin, and factors involved in the penetration of drugs through it.

Effects of regular insulin or insulin LISPRO on glucose metabolism after an oral glucose load in patients with type 2 diabetes mellitus.

Seven obese Type 2 diabetic patients were studied for two 4-h periods after ingestion of a glucose load to determine the effects of preprandial subcutaneous injection of Insulin Lispro (5 min before the meal) or regular insulin (20 min before the meal) on glucose metabolism. Glucose production and utilisation were measured using a dual isotope method. After Lispro, the mean postprandial increase in plasma glucose was 29% lower and the increase in insulin concentration 25% higher than after regular insulin (p < 0.05). Suppression of endogenous glucose production was similar with both types of insulin. Thus, preprandial injection of Lispro reduced postprandial glucose increments in Type 2 diabetic patients as compared to regular insulin. This effect is best explained by the increased postprandial bioavailability of Lispro.
