Objective: To build and validate an instrument to measure the perceived quality of life in the nutritional status. Material and methods: By focal groups and interviews with nutrition experts, the dimensions with greater affectation were identified. After the judge test, the CaVEN questionnaire was defined. For its valuation a multicentric study was performed, participating 7 Spanish hospitals. The internal structure of the questionnaire was evaluated by explanatory factorial analysis. Reliability was tested using the Cronbach [alpha] coefficient and the validity of the criteria with the nutritional Gold Standards. Results: A questionnaire of 26 items with 6 health dimensions was built. It was applied to 68 patients that were valued in the Nutrition Units. The test KMO was 0.756, showing a good accuracy in the Factorial Analysis. The existence of principal dimension of inertia was found (Bartlett p < 0.01). The 6 dimensions showed an accumulative variance of 77.670. It was observed a direct relationship in the Subjective Global Valuation and CaVEN (p < 0.01) and with the 'Mini Nutritional Assessment Short' (p = 0.02), which was interpreted as the greater affectation of the nutritional status, the lower the quality of life detected by the CaVEN. Conclusions: The CaVEN questionnaire has proved a useful tool for assessing the quality of life related to nutritional status, even in groups with little nutritional alterations.

Introduction: Research is usually considered a reliable indicator of the degree of development. Research in a problematic area such as food and nutrition for a given region, should have an impact on scientific production in agreement with the importance of the problem, the research capacity and the available resources for generating such a research. Objective: To identify some indicators of Iberoamerican research in nutrition and food. Method: Retrospective study of Iberoamerican scientific production in nutrition and food in the last 25 years. The data were obtained from the bibliographic database Science Citation Index Expanded, Journal Citation Reports Science Edition Database 2011, both included in the Web of Knowledge (Thomson Reuters), and the database of the World Bank. Results: 49,808 papers were registered, the 3.20% of the Health Sciences collection in SCI. The evolution was fitted to an exponential model, N&D (R² 0.962) and FS&T (R² 0.995). The average production in N&D per average population was higher in Spain with 0.659 papers/million. The highest rates of productivity and profitability were found in Guatemala with 12.963 papers/1000 researchers and 1.486 papers/million $ respectively. The average production in FS&T of the different countries per average population was higher in Cuba with 21.624 papers/million. The productivity index was higher in Uruguay with 25.999 papers/thousand researchers. The profitability index was higher in Guatemala with 0.271 papers/million $. Conclusion: There is exponential growth in the two categories studied N&D and FS&T. Productivity and profitability was higher in countries with low R&D (Research & Development) budget.

Background: Response Shift (RS) refers to the idea that an individual may undergo changes in its health-related quality of life (HRQOL). If internal standard, values, or reconceptualization of HRQOL change over time, then answer to the same items by the same individuals may not be comparable over time. Traditional measures to evaluate RS is prone to bias and strong methodologies to study the existence of this phenomenon is required. The objective is to systematically identify, analyze, and synthesize the existing and recent evidence of statistical methods used for RS detection in HRQOL studies., Methods: The analysis of selected studies between January 2010 and July 2020 was performed through a systematic review in MEDLINE/PubMed, Scopus, Web of Science, PsycINFO and Google Scholar databases. The search strategy used the terms "Health-Related Quality of Life" and "Response Shift" using the filters "Humans", "Journal Article", "English" and "2010/01/01-2020/07/31". The search was made in August 2020., Results: After considering the inclusion and exclusion criteria, from the total selected articles (675), 107 (15.9%) of the publications were included in the analysis. From these, 79 (71.0%) detected the existence of RS and 86 (80.4%) only used one detection method. The most used methods were Then Test (n = 41) and Oort's Structural Equation Models (SEM) (n = 35). Other method used were Multiple Lineal Regression (n = 7), Mixed-Effect Regression (n = 6), Latent Trajectory Analysis (n = 6), Item Response Theory (n = 6), Logistics Regression (n = 5), Regression and Classification Trees (n = 4) and Relative Importance Method (n = 4). Most of these detected recalibration, including Then Test (n = 27), followed by Oort's SEM that detected the higher combination of RS types: recalibration (n = 24), reprioritization (n = 13) and reconceptualization (n = 7)., Conclusions: There is a continuous interest of studying RS detection. Oort's SEM becomes the most versatile method in its capability for detecting RS in all different types. Despite results from previous systematic reviews, same methods have been used during the last years. We observed the need to explore other alternative methods allowing same detection capacity with robust and highly precise methodology. The investigation on RS detection and types requires more study, therefore new opportunity grows to continue attending this phenomenon through a multidisciplinary perspective., (© 2022.

Great efforts focus on early detection of autism spectrum disorder, although some scientists and policy-makers have questioned early universal screening. The aim of this meta-analysis was to evaluate the diagnostic accuracy of the different screening tools. Several electronic databases were used to identify published studies. A Bayesian model was used to estimate the screening accuracy. The pooled sensitivity was 0.72 (95% CI 0.61-0.81), and the specificity was 0.98 (95% CI 0.97-0.99). Subgroup analyses to remove heterogeneity indicated sensitivity was 0.77 (95% CI 0.69-0.84), and specificity was 0.99 (95% CI 0.97-0.99; SD ≤ 0.01). Level 1 screening tools for ASD showed consistent statistically significant results and therefore are adequate to detect autism at 14-36 months.

Objective: To perform a systematic review to analyze the association between occupational exposure to wood dust and cancer., Methods: A systematic literature search of entries made in the MEDLINE-PubMed database between 1957 and 2013 was conducted to identify studies that had assessed the relationship between occupational exposure to wood dust and different types of cancer. A meta-analysis of selected case-control and cohort studies was subsequently performed., Results: A total of 114 studies were identified and 70 were selected for review. Of these, 42 studies focused on the relationship between wood dust and nasal cancer (n = 22), lung cancer (n = 11), and other types of cancer (n = 9). Low-to-moderate quality evidence that wood dust acts as a carcinogen was obtained, and a stronger association between wood dust and nasal adenocarcinoma was observed. A lesser association between wood dust exposure and lung cancer was also observed. Several studies suggested that there is a relationship between wood dust and the onset of other cancers, although there was no evidence to establish an association. A meta-analysis that included four case-controls studies showed that workers exposed to wood dust exhibited higher rates of nasal adenocarcinoma than other workers (odds ratio = 10.28; 95% confidence interval: 5.92 and 17.85; P<0,0001), although a large degree of heterogeneity was found., Conclusions: Low-to-moderate quality evidence supports a causal association between cancer and occupational exposure to wood dust, and this association was stronger for nasal adenocarcinoma than for lung cancer. There was no evidence of an association between wood dust exposure and the other cancers examined.

Introduction: The quality of life of university students acquires special importance because it provides information about their life conditions and especially how they perceive it., Objective: Evaluate the quality of life of students who are enrolled in health science studies and its relation with the following diverse factors: life and dietetic habits, anthropometric parameters and the influence of distinct variables on their perception., Methods: Transversal study of a sample of 1753 health science degree students of nine Spanish universities with a randomized design and stratified by course and faculty for which we applied an ad hoc questionnaire that considered all study variables., Results: The quality of life (QoL) perceived by the participants had a Median of 75. The factors that were explored about the quality of life correlated significantly with their global perception of it (p., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.
