We name white coat effect (WCE) to the difference between the systolic arterial pressure (SAP)/diastolic AP (DAP) of consulting room and the ambulatory obtained one with ambulatory blood pressure ...monitoring (ABPM). In our work we analyzed by means of ABPM, the influence of the antihypertensive medicaments on the WCE and the cardiac frequency of use of the antihypertensive ones.
Almost experimental study (with a period before and a period later) and descriptive.
Primary care. Urban health centre. PARTICIPANTS AND MAIN MEASUREMENTS: Studies of ABPM were realized to 70 hypertense essential patients with good control of the arterial pressure after pharmacological treatment before suspending the antihypertensive medication (phase 1) and to the 4 weeks of leaving the treatment (phase 2).
Or all 70 hypertense patients. 18 (26%) did not manage to carry out the second ABPM (unbalanced during the wash) that forced to re-introduce the antihypertensive medicaments. The WCE systolic and diastolic is significantly more raised in patient males in treatment with diuretics with regard to which they use other pharmacological groups. The CF is significantly more raised in patient women who do not take blockaders thread (they use another group) with regard to they take it. In the blockaders alpha the CF is significantly more raised in the women who use it with regard to that they use antihypertensive other one. Of all 52 patients who were realized double ABPM, WCE was significantly top in phase 1 that in 2.
In hypertense controlled patients, the diuretics (in males) are the pharmacological group that of more significant way influences on WCE, them raising with regard to the patients who take antihypertensive other one, being in influence the opposite on CF. The women with blockaders thread present values of CF significantly lower than those who use another antihypertensive medication; happening the inverse thing the blockaders alpha. In our consulting room exists a inadequate use of the antihypertensive ones. The WCE is significantly mayor when is submitted to pharmacological treatment.
The stability of ranitidine hydrochloride in total nutrient admixtures (TNAs) containing 5% intravenous fat emulsion was studied. A TNA containing lipids and glucose was prepared aseptically in three ...ethylene-vinyl acetate bags. Ranitidine hydrochloride 100 mg and 200 mg was added to two of the bags to yield concentrations of 50 micrograms/mL and 100 micrograms/mL, respectively. The third bag served as a control. At 0, 12, 24, 48, and 72 hours, the ranitidine content was measured by high-performance liquid chromatography, the pH of the admixtures was determined, and the bags were visually inspected for signs of color changes, creaming, or precipitates. Particle-size distribution was measured at 72 hours and compared with that in the control bag at time zero. No appreciable changes in pH occurred over 72 hours, and no visual changes were observed. At concentrations of 50 and 100 micrograms/mL of admixture, ranitidine hydrochloride activity declined approximately 80% during the study period. Approximately 10% of the initial concentration was lost in 12 hours. In both cases, there was no variation in particle-size distribution compared with that in the control bag at time zero. Ranitidine hydrochloride appears to be stable for up to 12 hours at room temperature in the admixtures studied, and the lipid emulsion apparently was not altered during this period by ranitidine.
The stability of famotidine in two types of total nutrient admixtures (TNAs), one containing 5% intravenous fat emulsion of long-chain triglycerides and the other, of medium- and long-chain ...triglycerides, was studied. The TNAs, which contained lipids, glucose, amino acids, electrolytes, vitamins, and trace elements, were prepared aseptically in ethylene-vinyl acetate containers. Famotidine 40 mg was added to both types of TNAs and famotidine 80 mg was added to both types to yield concentrations of 20 and 40 mg/L (expressed hereafter as micrograms per milliliter), respectively. A control solution was prepared for each type of TNA. Samples were removed at 0, 12, 24, 48, and 72 hours for measurement of pH and of famotidine concentration by high-performance liquid chromatography; the solutions were visually inspected for color changes, creaming, and formation of precipitates. Particle size distributions were measured at 72 hours and compared with those for the control solutions at time zero. No appreciable changes in pH occurred over 72 hours, and no physicochemical changes were observed. Famotidine 20 and 40 micrograms/mL was stable for at least 72 hours in both types of TNAs. There was no variation in particle size distribution. Famotidine appears to be stable for up to 72 hours at room temperature in the TNAs studied, and it appears not to alter the integrity of the two lipid emulsions.
This paper analyses satisfaction with a cultural event, specifically in relation to an art exhibition. Following the literature in this field, satisfaction is measured as a post-consumption ...phenomenon omitting the role of expectations. A six-item satisfaction scale was then produced considering the main attributes of the exhibition. Data was collected from visitors after attending an exhibition of pinhole photography. The exhibition was organized by the Faculty of Economics (University of XXX, XXX) and it was held in two intermodal freight containers located on the university campus. Respondents were also asked to consider different aspects of their experience. Results show a high positive opinion on the overall exhibition and also in relation to some of its peripheral elements. Further implications for cultural events are also discussed.
