    Financiado para publicación en acceso aberto: Universidade da Coruña/CISUG.[Abstract:] Waves with periods between 25 s and some minutes can amplify the motions of moored ships, which may result in terminal downtimes and compromise safety. The purpose of this work is twofold: (i) studying infragravity waves and their influence on moored ship motions, including the definition of operational thresholds and (ii) developing a novel and integrated approach to identify and assess resonance situations using wavelet transform analysis. The resonant modes of the harbor basin were identified using a numerical model validated with full-scale data. The motions of five similar LPG vessels moored at two adjacent jetties were analyzed, both in the frequency and frequency–time domains. It was concluded that surge is the most important motion at the berth that has greater operational problems. Moreover, the infragravity motion periods vary with the mooring line pretension and are proportional to the ratio of water depth to vessel draft. Three episodes of mooring line breaking were attributed to large infragravity surge oscillations. In addition, operational thresholds for basin-vessel resonance situations were defined based on the port tide gauge data. A significant wave height of 0.075 and 0.010 m for the 30–65 s period band was established for LPGs and oil tankers, respectively.Ministerio de Economía, Industria y Competitividad; BIA2017-86738-RMinisterio de Ciencia e Innovación; PID2020-112794RB-I00 / AEI / 10.13039/501100011033Ministerio de Ciencia, Innovación y Universidades; PRE2018-08377

    Dental implant register : summary and consensus statements of group 2. The 5th EAO consensus conference 2018

    Get PDF
    Objectives: This publication reports the EAO Workshop group-2 and consensus plenary discussions and statements on a narrative review providing the background and possible facilities and importance of a dental implant register, to allow for a systematic follow-up of the clinical outcome of dental implant treatment in various clinical settings. It should be observed that the format of the review and the subsequent consensus report consciously departs from conventional consensus publications and reports. Material and methods: The publication was a narrative review on the presence and significance of quality registers regarding select medical conditions and procedures. The group discussed and evaluated the publication and made corrections and recommendations to the authors and agreed on the statements and recommendations described in this consensus report. Results: Possible registrations to be included in an implant register were discussed and agreed as a preliminary basis for further development, meaning that additional parameters be included or some be deleted. Conclusions: It was agreed to bring the idea of an implant quality register, including the presented results of discussions and proposals by the group- and plenary sessions, to the EAO Board for further discussion and decision

    Inorganic arsenic exposure may be associated with diabetes, but the evidence at low-moderate levels is not sufficient. Polymorphisms in diabetes-related genes have been involved in diabetes risk. We evaluated the association of inorganic arsenic exposure on diabetes in the Hortega Study, a representative sample of a general population from Valladolid, Spain. Total urine arsenic was measured in 1451 adults. Urine arsenic speciation was available in 295 randomly selected participants. To account for the confounding introduced by non-toxic seafood arsenicals, we designed a multiple imputation model to predict the missing arsenobetaine levels. The prevalence of diabetes was 8.3%. The geometric mean of total arsenic was 66.0 µg/g. The adjusted odds ratios (95% confidence interval) for diabetes comparing the highest with the lowest tertile of total arsenic were 1.76 (1.01, 3.09) and 2.14 (1.47, 3.11) before and after arsenobetaine adjustment, respectively. Polymorphisms in several genes including IL8RA, TXN, NR3C2, COX5A and GCLC showed suggestive differential associations of urine total arsenic with diabetes. The findings support the role of arsenic on diabetes and the importance of controlling for seafood arsenicals in populations with high seafood intake. Suggestive arsenic-gene interactions require confirmation in larger studies

    Treatment of stage I-III periodontitis-The EFP S3 level clinical practice guideline

    Get PDF
    Background: The recently introduced 2017 World Workshop on the classification of periodontitis, incorporating stages and grades of disease, aims to link disease classification with approaches to prevention and treatment, as it describes not only disease severity and extent but also the degree of complexity and an individual's risk. There is, therefore, a need for evidence-based clinical guidelines providing recommendations to treat periodontitis. Aim: The objective of the current project was to develop a S3 Level Clinical Practice Guideline (CPG) for the treatment of Stage I–III periodontitis. Material and Methods: This S3 CPG was developed under the auspices of the European Federation of Periodontology (EFP), following the methodological guidance of the Association of Scientific Medical Societies in Germany and the Grading of Recommendations Assessment, Development and Evaluation (GRADE). The rigorous and transparent process included synthesis of relevant research in 15 specifically commissioned systematic reviews, evaluation of the quality and strength of evidence, the formulation of specific recommendations and consensus, on those recommendations, by leading experts and a broad base of stakeholders. Results: The S3 CPG approaches the treatment of periodontitis (stages I, II and III) using a pre-established stepwise approach to therapy that, depending on the disease stage, should be incremental, each including different interventions. Consensus was achieved on recommendations covering different interventions, aimed at (a) behavioural changes, supragingival biofilm, gingival inflammation and risk factor control; (b) supra- and sub-gingival instrumentation, with and without adjunctive therapies; (c) different types of periodontal surgical interventions; and (d) the necessary supportive periodontal care to extend benefits over time. Conclusion: This S3 guideline informs clinical practice, health systems, policymakers and, indirectly, the public on the available and most effective modalities to treat periodontitis and to maintain a healthy dentition for a lifetime, according to the available evidence at the time of publication

    Prevention and treatment of peri-implant diseases—The EFP S3 level clinical practice guideline

    Get PDF
    Background: The recently published Clinical Practice Guidelines (CPGs) for the treatment of stages I–IV periodontitis provided evidence-based recommendations for treating periodontitis patients, defined according to the 2018 classification. Peri-implant diseases were also re-defined in the 2018 classification. It is well established that both peri-implant mucositis and peri-implantitis are highly prevalent. In addition, peri-implantitis is particularly challenging to manage and is accompanied by significant morbidity. Aim: To develop an S3 level CPG for the prevention and treatment of peri-implant diseases, focusing on the implementation of interdisciplinary approaches required to prevent the development of peri-implant diseases or their recurrence, and to treat/rehabilitate patients with dental implants following the development of peri-implant diseases. Materials and Methods: This S3 level CPG was developed by the European Federation of Periodontology, following methodological guidance from the Association of Scientific Medical Societies in Germany and the Grading of Recommendations Assessment, Development and Evaluation process. A rigorous and transparent process included synthesis of relevant research in 13 specifically commissioned systematic reviews, evaluation of the quality and strength of evidence, formulation of specific recommendations, and a structured consensus process involving leading experts and a broad base of stakeholders. Results: The S3 level CPG for the prevention and treatment of peri-implant diseases culminated in the recommendation for implementation of various different interventions before, during and after implant placement/loading. Prevention of peri-implant diseases should commence when dental implants are planned, surgically placed and prosthetically loaded. Once the implants are loaded and in function, a supportive peri-implant care programme should be structured, including periodical assessment of peri-implant tissue health. If peri-implant mucositis or peri-implantitis are detected, appropriate treatments for their management must be rendered. Conclusion: The present S3 level CPG informs clinical practice, health systems, policymakers and, indirectly, the public on the available and most effective modalities to maintain healthy peri-implant tissues, and to manage peri-implant diseases, according to the available evidence at the time of publication

    Diet quality index as a predictor of treatment efficacy in overweight and obese adolescents: The EVASYON study

    Get PDF
    Background & aim: A diet quality index (DQI) is a tool that provides an overall score of an individual''s dietary intake when assessing compliance with food-based dietary guidelines. A number of DQIs have emerged, albeit their associations with health-related outcomes are debated. The aim of the present study was to assess whether adherence to dietary intervention, and the overall quality of the diet, can predict body composition changes. Methods: To this purpose, overweight/obese adolescents (n = 117, aged: 13–16 years; 51 males, 66 females) were recruited into a multi-component (diet, physical activity and psychological support) family-based group treatment programme. We measured the adolescents’ compliance and body composition at baseline and after 2 months (intensive phase) and 13 months (extensive phase) of follow-up. Also, at baseline, after 6 months, and at the end of follow-up we calculated the DQI. Results: Global compliance with the dietary intervention was 37.4% during the intensive phase, and 14.3% during the extensive phase. Physical activity compliance was 94.1% at 2-months and 34.7% at 13months and psychological support compliance were growing over the intervention period (10.3% intensive phase and 45.3% during extensive phase). Adolescents complying with the meal frequency criteria at the end of the extensive phase had greater reductions in FMI z-scores than those did not complying (Cohen''s d = 0.53). A statistically significant association was observed with the diet quality index. DQI-A variation explained 98.1% of BMI z-score changes and 95.1% of FMI changes. Conclusions: We conclude that assessment of changes in diet quality could be a useful tool in predicting body composition changes in obese adolescents involved in a diet and physical activity intervention programme backed-up by psychological and family support

    Seminario “Promoción de hábitos saludables en adolescentes desde el ámbito educativo”.Objetivo: Evaluar el riesgo nutricional, por edad y sexo, que presentan los adolescentes escolarizados en la Comunidad Autónoma de Cantabria. Sujetos: Se realizó un estudio transversal, analizando una muestra de 1101 adolescentes, de los que 51,6% eran varones y 48,4% fueron mujeres de edades comprendidas entre los 10 y los 17 años, escolarizados en centros de enseñanza pública, mediante el cuestionario Krece Plus. Resultados: Se observa un elevado porcentaje de ado- lescentes que presentan un riesgo nutricional elevado (35%). Los varones presentan un riesgo nutricional alto en un porcentaje ligeramente superior a las mujeres (37,8 % vs 32,1%). Además, el riesgo nutricional alto sufre un notable incremento a medida que la edad de los jóvenes aumenta. Se aprecian diferencias estadísticamente signi- ficativas tanto en los grupos de edad de los varones (p = 0,024), de las mujeres (p < 0,001) como en el grupo global (p = 0,001). En los tres casos, la distribución del riego nutricional en los grupos de menor edad es muy similar (entre 35,2 y 35,8% en los h , entre 27,9 y 29,7% en las m , y entre 31,7 y 32,7% en el grupo total). Mientras que en el grupo de mayor edad estos valores prácticamente se duplican (57,1% en los h , 69,0% en las m , y 62,2 % en el grupo total). Conclusión: Los resultados obtenidos muestran una realidad preocupante debido, principalmente, al elevado porcentaje de adolescentes que presentan un riesgo nutri- cional elevado. Siendo los varones y los adolescentes de mayor edad los sectores en los que este riesgo nutricional elevado es superior.Objective: To analyse nutritional risk, by age and sex, among primary and secondary education adolescents from Cantabria. Methodology: a cross-sectional study was carried out, analysing a sample of 1101 adolescents: 568 (51.6%) were men and 533 (48.4%) were women, aged 12 to 17, attending 16 different primary and secondary education centres in Cantabria, by means of a Krece Plus questionnaire. Results: A high percentage of adolescents with a high nutritional risk (35%) can be observed. Men show a high nutritional risk slightly higher than women (37.8% h vs 32.1% m ). Moreover, the high nutritional risk expe riences a notable increase as young people get older. Significant statistical differences can be seen both in male and female groups, and as a global group. In all three cases, the nutritional risk distribution in the youngest group is very similar (35.2-35.8% in h , 27.9-29.7% in m , 31.7-32.7% in the global group); whereas in elder adolescents, those values are practically doubled (57.1% in h , 69.0% in m , y 62.2% in the global group). Conclusions: Results are alarming mainly given the high percentage of adolescents with a high nutritional risk. Men and older adolescents are the groups in which high nutritional risk is more evident

    Objetivo. Analizar determinadas prácticas alimentarias en adolescentes escolarizados en centros de educación pública de Cantabria, participantes en el Proyecto "Promoción de Hábitos Saludables en Adolescentes desde el Ámbito Educativo". Sujetos. Se realizó un estudio transversal, analizando una muestra de 1.101 adolescentes: 568 (51,6%) varones y 533 (48,4%) mujeres, de edades comprendidas entre los 10 y los 17 años, escolarizados en dieciséis centros de enseñanza primaria y secundaria, mediante un cuestionario autocumplimentado. Resultados. Los adolescentes suelen realizar entre cuatro (41,5%) y cinco (31,6%) ingestas diarias. Durante los días de colegio, el 34% emplea entre diez y quince minutos en desayunar, y entre 30 y 35 minutos en comer (33,5%) y cenar (23%). Un elevado porcentaje (49,4%) de adolescentes desayunaba en soledad durante los días lectivos. Las principales ingestas alimenticias se realizan en el hogar. Las bebidas no alcohólicas (53,6%) y los dulces (42%) son los principales destinos de su dinero de bolsillo. En la casi totalidad de los hogares, es la madre la que se encarga de la compra de los alimentos, de la preparación de las comidas y de decidir tanto el almuerzo como la merienda. La pizza (72,6%) y las patatas fritas (70,8%) son los alimentos considerados más ricos entre los analizados, mientras que el perrito caliente (49,4%) y la hamburguesa (48,5%) son considerados como los menos sanos. El 58,6% de los encuestados cena viendo la televisión. Conclusión. En el estudio del comportamiento alimentario es necesario analizar la influencia de otros factores que, en muchas ocasiones, están detrás de las recomendaciones dietéticas y que casi siempre son ignorados. Prácticas alimentarias como las analizadas en el presente estudio, permiten, cuando estas se desarrollan de forma adecuada, una mejora sustancial en la salud alimentaria y nutricional de las personas
