Results of a Professional Medical Counseling/surveillance in Preoperative Weight Loss

Background:Preoperative weight loss reduces the risk for complications after bariatric surgery.Objectives:To evaluate the effectiveness of a preoperative counseling program compared to general recommendations alone.Setting: Obesity Surgery Unit. Reina Sofia General University Hospital.  Murcia (southeast Spain).Methods: Prospective, randomized controlled study including 162 patients. Participants were randomly assigned to our preoperative intensive behavioral/lifestyle program (Counseling Group:55, 78% women) or to receive general nutritional recommendations (Reference Group:49, 82% women). Primary endpoint was a between-group comparison of percent excess weight loss (%EWL) at 4 months.Results: Counseling Group: baseline Body Mass Index (BMI)1was 45.9±7.3kg/m2 when  enrolled into the education program and reduced to to BMI2:43.2±5.6kg/m2 the day before the operation. After the motivational intervention, we got an average loss of 7.3±3.7kg of body weight and 12.4%EWL in 16 weeks.Reference Group: mean BMI1 was 45.5±7.3kg/m2. The day before surgery, BMI2 was: 46.1±6.1kg/m2. Over a period of 16 weeks the average weight gain was 1.8±1.1kg and -3%EWL (p=0.12). Weight gain was observed in 55% of these patients.The comparison of the mean %EWL in both groups did not reveal any statistically significant differences.  Conclusions: The educational intervention was not statistically significant more effective than general nutritional recommendations in achieving weight loss

How to link agricultural productivity, water availability and water demand in a risk context?

The importance of water scarcity in irrigated agriculture in Spain provides the rationale for this paper, which analyses and evaluates the risk of water shortage on the economic result of this kind of agriculture. The main objective is to monitor this risk on a real-time basis. For this aim, we first estimated a number of regression models that explain irrigated agricultural productivity based on crop price indices, a time trend and water availability. These models, which correct for auto-correlation, yield good explanatory power. Second we carried out ex ante simulations of agricultural productivity using fitted distribution functions of water balance. The risk model framework provides the basis for a real time drought management system through a variety of distribution functions of expected economic results, which can be revised on a monthly basis before the beginning of the irrigation season. The results of the simulation show how this kind of risk model can be used to anticipate the effects of droughts and complement the hydrological models used to manage water storage in years of scarcity. Different risk profiles are identified. For example, in Genil-Cabra we found that the resilience of the system after a drought period is very high, whereas in La Plana de Castellón the risk of irrigation area abandonment is increasing year by year. In Genil-Cabra the estimated losses were 60 million euros in 2007. The models were applied to some of the most agriculturally relevant irrigation districts in Spain

Economic analysis of drought risks: an application to irrigated agriculture in Spain

Abstract This paper describes a two-part methodology for managing the risk posed by water supply variability to irrigated agriculture. First, an econometric model is used to explain the variation in the production value of irrigated agriculture. The explanatory variables include an index of irrigation water availability (surface storage levels), a price index representative of the crops grown in each geographical unit, and a time variable. The model corrects for autocorrelation and it is applied to 16 representative Spanish provinces in terms of irrigated agriculture. In the second part, the fitted models are used for the economic evaluation of drought risk. In flow variability in the hydrological system servicing each province is used to perform ex-ante evaluations of economic output for the upcoming irrigation season. The model?s error and the probability distribution functions (PDFs) of the reservoirs? storage variations are used to generate Monte Carlo (Latin Hypercube) simulations of agricultural output 7 and 3 months prior to the irrigation season. The results of these simulations illustrate the different risk profiles of each management unit, which depend on farm productivity and on the probability distribution function of water in flow to reservoirs. The potential for ex-ante drought impact assessments is demonstrated. By complementing hydrological models, this method can assist water managers and decisionmakers in managing reservoirs

Disentangling the social, macro and micro-economic effects of agricultural droughts: An application to Spanish irrigated agriculture

Droughts affect irrigated agricultural production, reducing economic output and creating social stress. The economic consequences of droughts begin at the farm level, reaching the macro level along the production chain value. To the extent that crop markets adjust to the supply shocks and because droughts do not affect all sectors at the same time and with the same severity, it is instructive to conduct economic evaluations of drought effects at both micro- and macro-economic levels. The objective of this paper is to estimate the impact of water availability variations on the crops’ market values, the total value added of the agricultural sector and farm employment. We run regression models for these three economic variables and 14 provinces in Spain, comprising more than 50% of the Spanish irrigated area. Results show that the macro economic variables are only sensitive to water availability in the provinces where aridity and water stress are more severe. The value of the harvests obtained in irrigated land is largely explained by water availability. The time trend explains the largest percentage of variance of the three economic variables, including micro and macro

Observing the Onset of Effective Mass

The response of a particle in a periodic potential to an applied force is commonly described by an effective mass which accounts for the detailed interaction between the particle and the surrounding potential. Using a Bose-Einstein condensate of 87-Rb atoms initially in the ground band of an optical lattice, we experimentally show that the initial response of a particle to an applied force is in fact characterized by the bare mass. Subsequently, the particle response undergoes rapid oscillations and only over timescales long compared to that of the interband dynamics is the effective mass observed to be an appropriate description

A search for water maser emission toward obscured post-AGB star and planetary nebula candidates

Water maser emission at 22 GHz is a useful probe to study the transition between the nearly spherical mass-loss in the AGB to a collimated one in the post-AGB phase. In their turn, collimated jets in the post-AGB phase could determine the shape of planetary nebulae (PNe) once photoionization starts. We intend to find new cases of post-AGB stars and PNe with water maser emission, including water fountains or water-maser-emitting PNe. We observed water maser emission in a sample of 133 objects, with a significant fraction being post-AGB and young PN candidate sources with strong obscuration. We detected this emission in 15 of them, of which seven are reported here for the first time. We identified three water fountain candidates: IRAS 17291-2147, with a total velocity spread of ~96 km/s in its water maser components and two sources (IRAS 17021-3109 and IRAS 17348-2906) that show water maser emission outside the velocity range covered by OH masers. We have also identified IRAS 17393-2727 as a possible new water-maser-emitting PN. The detection rate is higher in obscured objects (14%) than in those with optical counterparts (7%), consistent with previous results. Water maser emission seems to be common in objects that are bipolar in the near-IR (43% detection rate). The water maser spectra of water fountain candidates like IRAS 17291-2147 show significantly less maser components than others (e.g., IRAS 18113-2503). We speculate that most post-AGBs may show water maser emission with wide enough velocity spread (> 100 km/s) when observed with enough sensitivity and/or for long enough periods of time. Therefore, it may be necessary to single out a special group of "water fountains", probably defined by their high maser luminosities. We also suggest that the presence of both water and OH masers in a PN is a better tracer of its youth, rather than the presence of just one of these species.Comment: To be published in Astronomy & Astrophysics. 16 pages, 1 figure (spanning 5 pages).
