Abstract: Objectives: According to the Brazilian Hospital Nutritional Assessment Inquiry, malnutrition in hospitals reaches 48.1% in Brazil, with this figure reaching as high as 63.9% in the northern and northeastern regions of the country. Despite its high prevalence, hospital malnutrition is not well identified by the majority of professionals on healthcare teams. The aim of the present study was to identify nutritional risk in patients hospitalized for clinical conditions. Method: This study was conducted at a university hospital in northeastern Brazil. Data were collected using the NRS 2002 screening tool (score ≥ 3 for nutritional risk) within 48 hours after admission to hospital. Results: Ninety-nine patients (44.4% men and 55.6% women; 58.6% elderly individuals and 41.4%) were studied between April and October 2010. Nutritional risk was identified in 39.4% upon admission to hospital. Reduced food intake and body mass index were associated with nutritional risk. Conclusions: A high percentage of clinical patients were at nutritional risk, which corroborates findings described in the literature. Low food intake was associated with nutritional risk. These results underscore the importance of nutritional care upon admission to hospital, which can contribute to improving or maintaining nutritional status and the avoidance of complications throughout the hospitalization period.

Abstract: Introduction: Although there are several studies in the international literature regarding hepatic steatosis, few large-scale studies of risk factors are available. Objective: To verify potential risk factors associated with hepatic steatosis, such as: alcohol consumption, overweight, dyslipidemia, hypertension, and type 2 diabetes mellitus. Methods: This is a case series study including a control group (without hepatic steatosis), carried out at the gastroenterology outpatient clinic in Northeast Brazil. The sample was composed of 219 patients with hepatic steatosis and 82 without the disease. Results: There was an association between hepatic steatosis and socioeconomic status. Prevalence Ratio (PR) for family income < 2 minimum wage was (PR = 1.35 CI 95%, 1.18-1.54) and education level < primary education (PR = 1.44, CI 95%,1.27-1.64). Regarding anthropometric and clinical characteristics and lipid profile, there was an association with overweight (PR = 1.59, CI 95%, 1.38-1.83), abdominal circumference in the range of very high risk (PR = 2.28, IC 95%,1.68-3.09), hypertension (PR = 1.30, CI 95%, 1.15-1.48) and type 2 diabetes mellitus (PR = 1.23, CI 95%, 1.07-1.64), low HDL-choles-terol (PR = 1,96, CI 95%, 1.55-2.48), hypertriglyceridemia (PR = 2.10, CI 95%, 1.64-2.68). In the regression model three variables remained independently associated to hepatic steatosis, abdominal circumference in the range of very high risk (PRadjusted = 1.74), low HDL-cholesterol (PRadjusted = 1.39) and overweight (PRadjusted = 1.28). Conclusion: The results showed an association of hepatic steatosis with some risk factors, being abdominal circumference (very high risk) the most strongly associated, followed by low HDL-cholesterol and overweight. Introducción: Aunque hay varios estudios en la literatura internacional sobre la esteatosis hepática, pocos estudios a gran escala de factores de riesgo están disponibles. Objetivo: Verificar potenciales factores de riesgo asociados a la esteatosis hepática como: consumo de alcohol, exceso de peso, dislipidemia, hipertensión arterial y diabetes mellitus tipo 2. Método: Estudio del tipo serie de casos, incluyendo un grupo control (sin esteatosis hepática), realizado en el ambulatorio de gastroenterología de un hospital universitario en el nordeste brasile o, compuesto por 219 pacientes con esteatosis hepática y 82 sin la enfermedad. Resultados: Hubo asociación entre la esteatosis hepática y condiciones socioeconómicas, el renta familiar < 2 salarios mínimos presentó Razón de Prevalencia (RP) = 1,35, IC 95%, 1,18-1,54) y escolaridad

Abstract: The discovery of argon from underground sources with significantly less 39Ar than atmospheric argon was an important step in the development of direct-detection dark matter experiments using argon as the active target. We report on the design and operation of a low background detector with a single phase liquid argon target that was built to study the 39Ar content of the underground argon. Underground argon from the Kinder Morgan CO2 plant in Cortez, Colorado was determined to have less than 0.65% of the 39Ar activity in atmospheric argon.

Abstract: The direct search for dark matter WIMP particles through their interaction with nuclei at the "neutrino floor" sensitivity, where neutrino-induced coherent scattering on nuclei starts contributing to the background, requires detectors capable of collecting exposures of the order of 1~ktonne yr free of background resulting from beta and gamma decays and cosmogenic and radiogenic neutrons. The same constraints are required for precision measurements of solar neutrinos elastically scattering on electrons. Two-phase liquid argon time projection chambers (LAr TPCs) are prime candidates for the ambitious program to explore the nature of dark matter. The large target, high scintillation light yield and good spatial resolution in all three cartesian directions concurrently allows a high precision measurement of solar neutrino fluxes. We studied the cosmogenic and radiogenic backgrounds affecting solar neutrino detection in a 300 tonne (100 tonne fiducial) LAr TPC operating at LNGS depth (3,800 meters of water equivalent). Such a detector could measure the CNO neutrino rate with 5 sigma sensitivity, and significantly improve the precision of the 7Be and pep neutrino rates compared to the currently available results from the Borexino organic liquid scintillator detector. Measurements with ~2%, ~10% and ~15% precision for 7Be, pep, and CNO neutrinos, respectively, are possible.

Abstract: Purification of the 278 tons of liquid scintillator and 889 tons of buffer shielding for the Borexino solar neutrino detector was performed with a system that combined distillation, water extraction, gas stripping and filtration. The purification of the scintillator achieved unprecedented low backgrounds for the large scale liquid scintillation detector. This paper describes the principles of operation, design, construction and commissioning of the purification system, and reviews the requirements and methods to achieve system cleanliness and leak-tightness.
