BACKGROUND: During stress, vasopressin is a potent synergistic factor of CRH as a hypothalamic stimulator of the HPA axis. The measurements of CRH and vasopressin levels are cumbersome because of their instability and short half-life. Copeptin is a more stable peptide stoichiometrically released from the same precursor molecule. The aim of our study was to compare copeptin and cortisol levels in different stress situations. METHODS: Three groups of patients with increasing stress levels were investigated: a) healthy controls without apparent stress (n=20), b) hospitalized medical patients with moderate stress (n=25) and c) surgical patients 30 minutes after extubation, with maximal stress (n=29). In all patients we assessed cortisol and copeptin levels. Copeptin levels were measured with a new sandwich immunoassay. RESULTS: Cortisol levels in controls were (median, IQ range, 486 [397-588] nmol/L), not significantly different as compared to medical patients (438 [371-612] nmol/L, p=0.69). Cortisol levels in surgical patients after extubation were higher (744 [645-1062] nmol/L p<0.01 vs controls and medical patients). Copeptin levels in controls were 4.3 [3.2-5.5] pmol/L, which was lower as compared to medical patients (17.5 [6.4-24.1], p<0.001) and surgical patients after extubation (67.5 [37.8-110.0] pmol/L, p<0.001). The correlation between copeptin levels and cortisol was r=0.46, p<0.001. CONCLUSION: Copeptin is a novel marker of the individual stress level. It more subtly mirrors moderate stress as compared to cortisol values.

This guidance is aimed at those responsible for helping people to change their behaviour to improve their health. This includes policy makers and those working in local authorities and the community and voluntary sectors. It gives advice on how to plan and run relevant initiatives. The recommendations include the following advice: base interventions on a proper assessment of the target group, where they are located and the behaviour which is to be changed: careful planning is the cornerstone of success  work with other organisations and the community itself to decide on and develop initiatives build on the skills and knowledge that already exists in the community, for example, by encouraging networks of people who can support each other take account of and resolve problems that prevent people changing their behaviour (for example, the costs involved in taking part in exercise programmes or buying fresh fruit and vegetables, or lack of knowledge about how to make changes) base all interventions on evidence of what works train staff to help people change their behaviour evaluate all interventions.This resource was contributed by The National Documentation Centre on Drug Use.

L'objectiu del TFC és el desenvolupament d'una aplicació informàtica sota la plataforma J2EE, implementant el patró model-vista-controlador. Per posar-ho en pràctica, es desenvoluparà una aplicació web que gestioni una companyia dedicada a la compra i venda de cotxes de segona mà. Es desenvoluparà tant la part empresarial relacionada amb la interacció amb els clients com la part administrativa, que permeti a la companyia gestionar la seva xarxa de concessionari i el personal que tenen contractat.

En els estudis d'enginyeria superior d'informàtica fets s'estudien els aspectes tècnics i metodològics de gestió de projectes informàtics. Ara bé, s'aborda breument un dels factors més importants i més determinants dels projectes: el factor humà. Aquest projecte complementa els coneixements sobre la gestió de projectes mitjançant un estudi sobre com el vessant humà afecta el desenvolupament d'un projecte informàtic. El projecte serveix de manual per a conèixer el funcionament d'un equip de projecte informàtic i de guia per a poder dirigir un equip d'aquestes característiques. Aquest treball permet saber per què pot funcionar un equip de projecte informàtic, quins factors individuals i de grup hi ha, quins són els seus participants i quines són les seves funcions, com s'organitzen, els problemes que hi poden aparèixer, i consells i estratègies per a aconseguir un equip eficient. Alhora, el projecte es complementa amb una sèrie d'experiències de persones que desenvolupen o han desenvolupat diferents rols dins equips de diferents projectes informàtics, que ajuden a entendre i identificar l'objectiu estudiat.

L'objectiu d'aquest treball és establir un criteri de classificació dels projectes informàtics, trobar-ne els diferents tipus i desenvolupar les estructures de descomposició del treball (EDT) per a cada tipus. Aquest criteri s'orientarà a fixar les màximes diferències entre tipus. Una vegada se'ls hagi localitzat, s'establiran les EDT corresponents a cada tipus, centrant el desenvolupament de cada estructura a reflectir les diferències entre les distintes descomposicions.

Physicians who frequently perform fluoroscopic examinations are exposed to high intensity radiation fields. The exposure monitoring is performed with a regular personal dosimeter under the apron in order to estimate the effective dose. However, large parts of the body are not protected by the apron (e.g. arms, head). Therefore, it is recommended to wear a supplemental dosimeter over the apron to obtain a better representative estimate of the effective dose. The over-apron dosimeter can also be used to estimate the eye lens dose. The goal of this study was to investigate the relevance of double dosimetry in interventional radiology. First the calibration procedure of the dosimeters placed over the apron was tested. Then, results of double dosimetry during the last five years were analyzed. We found that the personal dose equivalent measured over a lead apron was underestimated by ∼20% to ∼40% for X-ray beam qualities used in radiology. Measurements made over five-year period confirm that the use of a single under-apron dosimeter is inadequate for personnel monitoring. Relatively high skin dose (>10 mSv/month) would have remained undetected without a second dosimeter placed on the apron.

Excessive exposure to solar UV light is the main cause of skin cancers in humans. UV exposure depends on environmental as well as individual factors related to activity. Although outdoor occupational activities contribute significantly to the individual dose received, data on effective exposure are scarce and limited to a few occupations. A study was undertaken in order to assess effective short-term exposure among building workers and characterize the influence of individual and local factors on exposure. The effective exposure of construction workers in a mountainous area in the southern part of Switzerland was investigated through short-term dosimetry (97 dosimeters). Three altitudes, of about 500, 1500 and 2500 m were considered. Individual measurements over 20 working periods were performed using Spore film dosimeters on five body locations. The postural activity of workers was concomitantly recorded and static UV measurements were also performed. Effective exposure among building workers was high and exceeded occupational recommendations, for all individuals for at least one body location. The mean daily UV dose in plain was 11.9 SED (0.0-31.3 SED), in middle mountain 21.4 SED (6.6-46.8 SED) and in high mountain 28.6 SED (0.0-91.1 SED). Measured doses between workers and anatomical locations exhibited a high variability, stressing the role of local exposure conditions and individual factors. Short-term effective exposure ranged between 0 and 200% of ambient irradiation, indicating the occurrence of intense, subacute exposures. A predictive irradiation model was developed to investigate the role of individual factors. Posture and orientation were found to account for at least 38% of the total variance of relative individual exposure, and were also found to account more than altitude on the total variance of effective daily exposures. Targeted sensitization actions through professional information channels and specific prevention messages are recommended. Altitude outdoor workers should also benefit from preventive medical examination.
