How High Dose(s) of Oral Vitamin D3 Can Correct Insufficiency in a Non Supplemented Rheumatologic Population ?

Introduction: 700 to 1000 UI Vitamin D/day prevent 20% of fall and fracture. Higher dosage could prevent other health problems, such as immune diseases. Adherence to oral daily vitamin D supplementation is low. There is no guideline on how to supplement patients with rheumatic diseases. We evaluated if 1-2 dose(s) of 300'000 UI oral vitamin D3 was enough to reach an optimal level of 25-OH vitamin D in late winter in patients with insufficiency. Methods: During November 2009 (M0) patients attending our Rheumatology Outpatient Clinic had a blood test to measure 25-OH vitamin D. Results were classified as: deficiency <10µg/l, insufficiency 10µg/l to 30µg/l and normal >30µg/l. Patients on daily oral vitamin D3 or who received a single high dose of vitamin D3 in the last 6 months and patients with deficiency or normal results were excluded. Patients included received a single dose of 300'000 IU of oral vitamin D3 and were asked to come back for a blood test for 25-OH vitamin D after 3 (M3) and 6 months (M6). If they were still insufficient at M3, they received a second high dose of 300'000 IU of oral vitamin D3. Results: 292 patients had their level of 25-OH vitamin D determined at M0. 141 patients (70% women) had vitamin D insufficiency (18.5µg/l (10.2-29.1)) and received a prescription for a single dose of 300'000 IU of oral vitamin D3. Men and women were not statistically different in term of age and 25-OH vitamin D level at M0. 124/141 (88%) patients had a blood test at M3. 2/124 (2%) had deficiency (8.1µg/l (7.5-8.7)), 50/124 (40%) normal results (36.7µg/l (30.5-56.5)). 58% (72/124) were insufficient (23.6µg/l (13.8-29.8)) and received a second prescription for 300'000 IU of oral vitamin D3. Of the 50/124 patients who had normal results at M3 and did not receive a second prescription, 36 (72%) had a test at M6. 47% (17/36) had normal results (34.8µg/l (30.3-42.8)), 53% (19/36) were insufficient (25.6µg/l (15.2-29.9)). Out of the 54/72 (75%) patients who received a second prescription, 28/54 (52%) had insufficiency (23.2µg/l (12.8-28.7)) and 26/54 (48%) had normal results (33.8µg/l (30.0-43.7)) at M 6. Discussion: This real life study has shown that one or two oral bolus of 300'000 IU of vitamin D3 in autumn and winter was not enough to completely correct hypovitaminosis D but was a good way of preventing a nadir of 25-OH vitamin D usually observed in spring in a Swiss rheumatologic population.

Chronic inflammation and fatty acid deficiency, in particular in docosahexaenoic acid (DHA, C22:6-n3), occurring in cystic fibrosis patients, are two convincing arguments urging the use of polyunsaturated fatty acids (PUFA) omega-3 in this population. PUFA omega-3 oral dietary intake position in the cystic fibrosis treatment is however not clear despite many years of clinical research. This review article sets out the reasons that conduct nutritionists to try this approach and reviews the results published until nowadays.

Serum antimüllerian hormone levels remain stable through the menstrual cycle and after oral or vaginal administration of synthetic sex steroids

Rapport de synthèse : Objectif de l'étude : étudier si l'administration orale ou vaginale d'hormones contraceptives influence les concentrations sériques d'hormone antimüllérienne (AMH). Design : essai prospectif chez des femmes recrutées par annonce. Les femmes désireuses d'avoir une contraception ont été randomisées entre une contraception orale et une contraception vaginale. Celles qui ne souhaitaient pas de contraception ont été incluses dans le groupe témoin. Cadre de l'étude : unité de médecine de la reproduction d'un hôpital universitaire. Patientes : vingt-quatre jeunes femmes en bonne santé avec des cycles menstruels réguliers qui n'avaient pas utilisé de contraception hormonale pendant les trois mois précédant l'étude. Intervention : contraception orale ou vaginale du 5ème au 25ème jour du cycle menstruel dans les groupes contraception versus pas de contraception dans le groupe témoin. Mesure d'issue : variations inter et intra-cycle des concentrations sériques d'AMH dans les trois groupes: groupe témoin en cycle spontané et groupes sous contraception oestroprogestative orale ou vaginale. Résultats : les fluctuations d'AMH observées pendant le cycle menstruel (variations intra-cycle) restent dans les valeurs des variations entre deux cycles (variations inter-cycles) tant chez les femmes en cycle spontané que chez les femmes sous contraception orale ou vaginale. Conclusions : nos résultats confirment que les concentrations sériques d'AMH restent stables pendant le cycle menstruel et indiquent qu'elles ne sont pas influencées par l'administration exogène de stéroïdes sexuels contraceptifs, que ce soit par voie orale ou vaginale.

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.
