Àcid fòlic; Hhomocisteïna; Deteriorament cognitiu lleuÁcido fólico; Homocisteína; Deterioro cognitivo leveFolic acid; Homocysteine; Mild cognitive impairmentHyperhomocysteinemia is an independent predictor of the risk for cognitive decline and may be a result of low levels of vitamins B12, B6, and folate. Previous findings suggest that adequate intake of these vitamins may reduce homocysteine levels. This review aimed to assess the effects of treatment with vitamins B6, B12, and/or folic acid in the homocysteine levels in patients with mild cognitive impairment (MCI). A systematic literature review was conducted in EMBASE, MEDLINE®, PsycINFO, and Cochrane Central Register of Controlled Trials. The research question was formulated using the Population, Intervention, Comparison, and Outcome (PICO) framework: in patients with MCI (P); what is the efficacy of vitamins B6, B12, and/or folic acid intake (I); compared with baseline values, and/or compared with controls (C); in reducing homocysteine levels from baseline (O). A total of eight primary studies with a total of 1,140 participants were included in the review. Four were randomized controlled trials, one was a quasi-controlled trial, and three were observational studies. All studies included folic acid in their intervention, seven vitamin B12, and four vitamin B6. Mean (SD) length of the intervention period was 18.8 (19.3) months, ranging from 1 to 60 months. All studies showed a statistically significant decrease in homocysteine levels in groups treated with vitamins B6, B12, and/or folic acid compared to controls, with a mean decline of homocysteine concentration of 31.9% in the intervention arms whereas it increased by 0.7% in the control arm. This review identified evidence of a reduction of plasma homocysteine levels in MCI patients taking vitamins B6, B12, and/or folic acid supplements, with statistically significant declines being observed after 1 month of supplementation. Findings support that supplementation with these vitamins might be an option to reduce homocysteine levels in people with MCI and elevated plasma homocysteine.Nestlé Health Science, Switzerlan

X-ray properties of a sample of NLS1 selected from the SDSS

Galaxy surveys have revealed the existence of Narrow Emission Line Galaxies (NELG) which are spectroscopically classified as starforming (SF), but whose X-ray luminosity exceeds 1042 erg s?1 which unambiguously signals the presence of an AGN. The origin for such a discrepancy is not understood. In order to addres this issue, we present a study using a large sample of 239 NELG (FWHM(H? ) < 1200 km/s) from the SDSS, for which we can construct the BPT diagram and that are detected in the hard (2?10 keV) X-ray band within the 2XMM X-ray source catalogue. We find that 33 of these objects are diagnosed as starforming galaxies but their X-ray luminosity exceeds 1042 erg s?1 . We conducted a detailed analysis of this population, using other optical spectral features,like the FWHM of the H? emission line and the X-ray spectral properties. We find that the bulk of this misclassified population, which represents over 10% of our full sample of hard X-ray detected NELGs, is constituted by NLS1 galaxies.Partial financial support for this work was provided by the spanish Ministry of Science and Innovation, through grant AYA2009-08059

Prevalence of Fetal Alcohol Spectrum Disorders (FASD) among Children Adopted from Eastern European Countries: Russia and Ukraine

Fetal alcohol spectrum disorders; Adopted children; Cognitive disorderTrastornos del espectro alcohólico fetal; Niño adoptado; Trastorno cognitivoTrastorns de l'espectre alcohòlic fetal; Nens adoptats; Trastorn cognitiuFetal alcohol spectrum disorder (FASD) is a leading cause of neurodevelopmental disorders. Children adopted internationally from countries where alcohol consumption during pregnancy is very high are at greater risk for FASD. Lack of expertise in diagnosing FASD and mixed neurodevelopmental and behavioral signs due to abandonment complicate a timely diagnosis. The aim of this study was to determine the prevalence of FASD in adopted children. Children between the ages of 8 and 24 adopted from Russia and Ukraine were evaluated for clinical and historical features of FASD. Of the 162 children evaluated, 81 (50%) met FASD diagnostic criteria. Thirty-three (20.4%) children had fetal alcohol syndrome (FAS), 28 (17.2%) had partial FAS, 2 (1.2%) had alcohol-related birth defects (ARBD) and 18 (11.1%) had alcohol-related neurodevelopmental disorder (ARND). Of the 81 children in which fetal alcohol exposure could not be confirmed, many had manifestations that would have established a diagnosis of FASD if a history of maternal alcohol consumption was confirmed. In a population of children with a high risk of prenatal alcohol exposure (adoptees from Eastern European countries), at least 50% showed manifestations associated with FASD. The reported prevalence in this study is in line with the results obtained in a previous study as well as in orphanages of origin

We aimed to assess the hydration status in patients with OD and the effect TF therapy has on it. Methods: Two literature reviews following PRISMA methodology (each one including a systematic and a scoping review) were performed: (R1) hydration status in adult patients with OD; (R2) effect of TF therapy on fluid intake and dehydration. Narrative and descriptive methods summarized both reviews. Quality assessment was assessed by Joanna Briggs Institute tools and GRADE. Results: (R1) Five out of twenty-two studies using analytical parameters or bioimpedance showed poorer hydration status among OD and 19-100% prevalence of dehydration; (R2) two high quality studies (total of 724 participants) showed positive effects of TF on hydration status. Among the articles included, nine out of ten studies that evaluated fluid intake reported a reduced TF intake below basal water requirements. Conclusions: Dehydration is a highly prevalent complication in OD. There is scientific evidence on the positive effect of TF therapy on the hydration status of patients with OD. However, strict monitoring of fluid volume intake is essential due to the low consumption of TF in these patients

Use of health resources and healthcare costs associated with nutritional risk: The FRADEA study

BACKGROUND: In spite of its high prevalence and its clinical relevance, the economic impact of malnutrition has not been sufficiently explored. OBJECTIVE: To study whether malnutrition predicts total hospital healthcare costs and costs related to specialist visits, emergency department visits and hospitalization in older adults. METHODS: Concurrent cohort study in Albacete City, Spain. The study sample included 827 subjects aged 70 and over from the FRADEA Study. Mini Nutritional Assessment®-Short Form (MNA®-SF) was recorded at baseline. Use of hospital resources (hospital admissions, emergency visits, and specialist visits), and hospital healthcare costs were recorded at follow-up. Generalized linear models (GLM) adjusted for age, sex, comorbidity, polypharmacy, and disability in basic activities of daily living were used to estimate the impact of nutritional factors on total healthcare costs per person/year (€ base year 2013) as well as specialist visit costs, emergency department visit costs and hospitalization costs. RESULTS: The average cost associated with the use of health resources was 1922€/year. Subjects with MNA®-SF between 0 and 7 had an average total health cost of 3492€/year, 2744€/year in those with MNA®-SF between 8 and 11, and 1542€/year in those with MNA®-SF between 12 and 14. Of the total health cost, 67.2% was associated with hospital admission costs. Adjusted healthcare costs were 714€/year greater in subjects with malnutrition or nutritional risk. Subjects with malnutrition or nutritional risk presented an increased adjusted risk of hospitalization (OR1.72, 95% CI 1.22-2.43). CONCLUSIONS: Malnutrition assessed by MNA®-SF is a prognostic factor of high healthcare cost and use of resources in older adults

Propiedades nutricionales, microbiológicas y costes de producción de las dietas de textura modificada en las residencias de ancianos. El estudio ABADÍA.

Introduction: although nutritional differences between different types of texture-modified diet (TMD) have been evaluated, the resources and costs associated with their preparation have been less studied. Objective: to describe the nutritional, microbiological properties and costs of: 1) in-home produced pureed food (hTMD); 2) concentrated nutrient-dense commercial food products, hand-blended (cTMD); 3) food prepared using the MixxPro® automatic food mixer (cTMD-Mix). Methods: an observational, prospective study carried out in three geriatric nursing-homes. Patients ≥ 65 years, receiving TMD, with a stable clinical condition, estimated survival/expected internment > 1 month, and sufficient cognitive capacity were included. The following data were recorded: 1) patient socio-demographic and clinical variables; 2) TMD compliance and symptoms related to dysphagia during the meal; 3) patient appetite; and 4) kitchen information and resources used to prepare a TMD. Results: sixty-two residents were included (65.0 % women, 88.3 years (SD: 9.3); 43.5 % malnourished, 79.0 % with good appetite). The proportion of food eaten/median kcal served/portion/mean kcal consumed were: hTMD: 95.5 % (SD: 10.7)/92.4 kcal (IQR: 75.6-128.1)/88.2 kcal (IQR: 72.2-122.3); cTMD: 89.2 % (SD: 15.9)/323.4 kcal (IQR: 284.2-454.1)/288.5 kcal (IQR: 253.5-325.1); and cTMD-Mix: 80.3 % (SD: 21.4)/358.0 kcal (IQR: 344.0-372.1)/287.5 kcal (IQR: 276.5-298.8). No microorganisms were detected. The average time spent in preparing each portion and its costs were: hTMD: 11.2 min (SD: 3.89)/€2.33 (SD: 0.63); cTMD: 1.7 min (SD: 0.28)/€2.01 (SD: 0.39); and cTMD-Mix: 1.6 min (SD: 0.00)/€2.00 (SD: 0.33). Conclusions: in patients with dysphagia and/or chewing difficulties, concentrated nutrient-dense food products, particularly those produced using the MixxPro® automatic food mixer, ensure a high caloric intake and allow quick and safe food preparation
