Recubrimientos de vidrios de fosfatos de calcio sobre circonas
Se presentan los resultados obtenidos en la preparación y caracterización microestructural de un recubrimiento de vidrio de fosfato de calcio (biovidrio) sobre dos substratos cerámicos de circona. Los tratamientos térmicos se llevaron a cabo a 1 100 °C durante 2 h en aire. Los materiales se caracterizaron empleando microscopa electrónica de barrido (MEB) y de barrido ambiental (MEBA), difracción de rayos-X (DRX) y microanálisis por separación de energías de rayos-X (SERX) acoplado al MEB. Además, se estudiaron
los cambios ocurridos en las superficies de los materiales después de dos semanas en una disolución fisiológica simulada (DFS). Las observaciones por MEB revelaron una buena deposición de la capa de biovidrio sobre los dos substratos de circona. Los resultados de microanálisis por SERX demostraron la difusión del magnesio de la estructura de la circona hacia el vidrio en el caso de los substratos estabilizados con óxido de magnesio, así como la difusión del calcio desde la capa de biovidrio a la
circona estabilizada en este caso con óxido de itrio. En el caso de los resultados de difracción de rayos-X, la formación de nuevas fases asociadas a cierta cristalización del biovidrio, así como a la difusión del calcio y magnesio antes mencionada le confieren una determinada complejidad a su interpretación. En cuanto al comportamiento después de dos semanas en DFS, las observaciones por MEB y MEBA permitieron apreciar cambios significativos en la microestructura de la capa de biovidrio asociados a su degradación

Effectiveness of an mHealth Intervention Combining a Smartphone App and Smart Band on Body Composition in an Overweight and Obese Population: Randomized Controlled Trial (EVIDENT 3 Study)
[EN]Background: Mobile health (mHealth) is currently among the supporting elements that may contribute to an improvement in
health markers by helping people adopt healthier lifestyles. mHealth interventions have been widely reported to achieve greater
weight loss than other approaches, but their effect on body composition remains unclear.
Objective: This study aimed to assess the short-term (3 months) effectiveness of a mobile app and a smart band for losing
weight and changing body composition in sedentary Spanish adults who are overweight or obese.
Methods: A randomized controlled, multicenter clinical trial was conducted involving the participation of 440 subjects from
primary care centers, with 231 subjects in the intervention group (IG; counselling with smartphone app and smart band) and 209
in the control group (CG; counselling only). Both groups were counselled about healthy diet and physical activity. For the 3-month
intervention period, the IG was trained to use a smartphone app that involved self-monitoring and tailored feedback, as well as
a smart band that recorded daily physical activity (Mi Band 2, Xiaomi). Body composition was measured using the InBody 230
bioimpedance device (InBody Co., Ltd), and physical activity was measured using the International Physical Activity Questionnaire. Results: The mHealth intervention produced a greater loss of body weight (–1.97 kg, 95% CI –2.39 to –1.54) relative to standard
counselling at 3 months (–1.13 kg, 95% CI –1.56 to –0.69). Comparing groups, the IG achieved a weight loss of 0.84 kg more
than the CG at 3 months. The IG showed a decrease in body fat mass (BFM; –1.84 kg, 95% CI –2.48 to –1.20), percentage of
body fat (PBF; –1.22%, 95% CI –1.82% to 0.62%), and BMI (–0.77 kg/m2, 95% CI –0.96 to 0.57). No significant changes were
observed in any of these parameters in men; among women, there was a significant decrease in BMI in the IG compared with the
CG. When subjects were grouped according to baseline BMI, the overweight group experienced a change in BFM of –1.18 kg
(95% CI –2.30 to –0.06) and BMI of –0.47 kg/m2 (95% CI –0.80 to –0.13), whereas the obese group only experienced a change
in BMI of –0.53 kg/m2 (95% CI –0.86 to –0.19). When the data were analyzed according to physical activity, the moderate-vigorous
physical activity group showed significant changes in BFM of –1.03 kg (95% CI –1.74 to –0.33), PBF of –0.76% (95% CI –1.32%
to –0.20%), and BMI of –0.5 kg/m2 (95% CI –0.83 to –0.19).
Conclusions: The results from this multicenter, randomized controlled clinical trial study show that compared with standard
counselling alone, adding a self-reported app and a smart band obtained beneficial results in terms of weight loss and a reduction
in BFM and PBF in female subjects with a BMI less than 30 kg/m2 and a moderate-vigorous physical activity level. Nevertheless,
further studies are needed to ensure that this profile benefits more than others from this intervention and to investigate modifications
of this intervention to achieve a global effect.[EN]This study was funded by the Spanish Ministry of Science and Innovation, Instituto de Salud Carlos III, and co-funded by the

Long-term Effectiveness of a Smartphone App Combined With a Smart Band on Weight Loss, Physical Activity, and Caloric Intake in a Population With Overweight and Obesity (Evident 3 Study): Randomized Controlled Trial
[EN]Background: Multicomponent mobile health approaches can improve lifestyle intervention results, although little is known
about their long-term effectiveness.
Objective: This study aims to evaluate the long-term effectiveness (12 months) of a multicomponent mobile health
intervention—combining a smartphone app, an activity tracker wristband, and brief counseling, compared with a brief counseling
group only—on weight loss and improving body composition, physical activity, and caloric intake in Spanish sedentary adults
with overweight or obesity.
Methods: We conducted a randomized controlled, multicenter clinical trial (Evident 3). A total of 650 participants were recruited
from 5 primary care centers, with 318 participants in the intervention group (IG) and 332 in the control group (CG). All participants
were briefly counseled about a healthy diet and physical activity at the baseline visit. For the 3-month intervention period, the
IG received training to use the app to promote healthy lifestyles and the smart band (Mi Band 2, Xiaomi). All measurements were
performed at baseline and at 3 and 12 months. Physical activity was measured using the International Physical Activity Questionnaire–Short Form. Nutritional habits were assessed using the Food Frequency Questionnaire and Adherence to
Mediterranean diet questionnaire.
Results: Of the 650 participants included, 563 (86.6%) completed the 3-month visit and 443 (68.2%) completed the 12-month
visit. After 12 months, the IG showed net differences in weight (−0.26, 95% CI −1.21 to 0.70 kg; P=.02), BMI (−0.06, 95% CI
−0.41 to 0.28 points; P=.01), waist-height ratio (−0.25, 95% CI −0.94 to 0.44; P=.03), body adiposity index (−0.33, 95% CI −0.77
to 0.11; P=.03), waist circumference (−0.48, 95% CI −1.62 to 0.66 cm, P=.04) and hip circumference (−0.69, 95% CI –1.62 to
0.25 cm; P=.03). Both groups lowered daily caloric intake and increased adherence to the Mediterranean diet, with no differences
between the groups. The IG increased light physical activity time (32.6, 95% CI −30.3 to 95.04 min/week; P=.02) compared with
the CG. Analyses by subgroup showed changes in body composition variables in women, people aged >50 years, and married
people.
Conclusions: The low-intensity intervention of the Evident 3 study showed, in the IG, benefits in weight loss, some body
composition variables, and time spent in light physical activity compared with the CG at 3 months, but once the devices were
collected, the downward trend was not maintained at the 12-month follow-up. No differences in nutritional outcomes were
observed between the groups.This study was funded by the Spanish Ministry of Science and Innovation, Instituto de Salud Carlos III and cofunded by the

Cardiovascular risk stratification using the globorisk scale in the population of the Czech Republic
[eng] Introduction: The risk of cardiovascular disease can be determined with a multitude of scales. The present study aims to determine the level of cardiovascular risk in population of the Czech Republic by applying the Globorisk scale. Methods: A descriptive, cross-sectional study of 28234 persons aged 40-74 years in whom cardiovascular risk was assessed using the Globorisk scale adapted to the population of the Czech Republic. The influence of sociodemographic variables (age, sex and social class) and tobacco consumption on the values of this scale was assessed. Results: Both the mean values and the prevalence of high values of the Globorisk scale are higher in males, in older people, in people with lower socioeconomic status and in smokers. The variable that most influences the occurrence of high values of the scale is male sex with an odds ratio of 39.71 (95% CI 29.79-52.92). Conclusions: All the sociodemographic variables analyzed, as well as tobacco consumption, influence the values of the Globorisk scale
Changing paradigms in seagrass restoration
Sharing experiences and results among scientists and managers working on seagrass restoration was the main objective of the first European Seagrass Restoration Workshop that gathered researchers from around Europe. The meeting was the first forum in Europe that allowed for scientists, NGOs, and managers to interact and share their experiences relating to seagrass restoration and management. The results show that none of the seagrass restoration programs developed in Europe by the participants during the last 10 years was successful. Furthermore, an informal review of data published in seagrass restoration success, showed that the results reported were biased because they were mostly based on a very short monitoring period (i.e. <1 year). Numerous decision trees, guidelines, and restoration models have been developed to aid seagrass restoration management, but the results of this workshop point toward a new paradigm in seagrass restoration were efforts should shift to give priority to natural restoration potential, with an emphasis on the fact that restoration should never be considered the first alternative when planning for the mitigation of coastal development projects or to justify mitigation as a compensation measure for economic activities. © 2012 Society for Ecological Restoration International.This research was funded by the European commission through the LIFE Biomares project (LIFE 06 NAT/P/192)Peer Reviewe
