The relationship of the atlantic diet with cardiovascular risk factors and markers of arterial stiffness in adults without cardiovascular disease

Background: Studying the adherence of the population to the Atlantic Diet (AD) could be simplified by an easy and quickly applied dietary index. The aim of this study is to analyse the relationship of an index measuring compliance with recommendations regarding the Atlantic diet and physical activity with cardiovascular disease risk factors, cardiovascular risk factors, obesity indexes and arterial stiffness markers. Methods: We included 791 individuals from the EVIDENT study (lifestyles and arterial ageing), (52.3 ± 12 years, 61.7% women) without cardiovascular disease. Compliance with recommendations on AD was collected through the responses to a food frequency questionnaire, while physical activity was measured by accelerometer. The number of recommendations being met was estimated using a global scale between 0 and 14 points (a higher score representing greater adherence). Blood pressure, plasma lipid and glucose values and obesity rates were measured. Cardiovascular risk was estimated with the Framingham equation. Results: In the overall sample, 184 individuals (23.3%) scored between 0–3 on the 14-point index we created, 308 (38.9%) between 4 and 5 points, and 299 (37.8%) 6 or more points. The results of multivariate analysis yield a common tendency in which the group with an adherence score of at least 6 points shows lower figures for total cholesterol (p = 0.007) and triglycerides (p = 0.002). Similarly, overall cardiovascular risk in this group is the lowest (p < 0.001), as is pulse wave velocity (p = 0.050) and the mean values of the obesity indexes studied (p < 0.05 in all cases). Conclusion: The rate of compliance with the Atlantic diet and physical activity shows that greater adherence to these recommendations is linked to lower cardiovascular risk, lower total cholesterol and triglycerides, lower rates of obesity and lower pulse wave velocity values

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)

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

Spread of a SARS-CoV-2 variant through Europe in the summer of 2020.

Following its emergence in late 2019, the spread of SARS-CoV-21,2 has been tracked by phylogenetic analysis of viral genome sequences in unprecedented detail3–5. Although the virus spread globally in early 2020 before borders closed, intercontinental travel has since been greatly reduced. However, travel within Europe resumed in the summer of 2020. Here we report on a SARS-CoV-2 variant, 20E (EU1), that was identified in Spain in early summer 2020 and subsequently spread across Europe. We find no evidence that this variant has increased transmissibility, but instead demonstrate how rising incidence in Spain, resumption of travel, and lack of effective screening and containment may explain the variant’s success. Despite travel restrictions, we estimate that 20E (EU1) was introduced hundreds of times to European countries by summertime travellers, which is likely to have undermined local efforts to minimize infection with SARS-CoV-2. Our results illustrate how a variant can rapidly become dominant even in the absence of a substantial transmission advantage in favourable epidemiological settings. Genomic surveillance is critical for understanding how travel can affect transmission of SARS-CoV-2, and thus for informing future containment strategies as travel resumes. © 2021, The Author(s), under exclusive licence to Springer Nature Limited

New synthesis of all four 1-amino-2-hydroxycyclohexanecarboxylic acids

This report describes a new synthesis of the four stereoisomers of 1-amino-2-hydroxycyclohexanecarboxylic acids [(1S,2S)-, (1R,2R)-, (1S,2R)- and (1R,2S)-c 6Ser], four conformationally constrained serine (Ser) analogues, possessing a six-membered carbocyclic ring. Initially, we synthesised cis-c 6Ser and trans-c 6Ser in their racemic forms, using as key steps the Diels-Alder reactions of methyl 2-benzamidoacrylate with Danishefsky's diene and 1-methoxy-1,3-butadiene, respectively. The optically active forms were achieved by resolution methods. © 2001 Elsevier Science Ltd

Modelos teóricos de promoción de la salud en la práctica habitual en atención primaria de salud

Objetivo: Comprender a qué modelos teóricos se ajusta la práctica actual de la prevención primaria ypromoción de la salud en atención primaria de salud en diferentes centros de salud de siete comunidadesautónomas de España, según los/las profesionales de distintas disciplinas de este ámbito asistencial. Método: Investigación cualitativa descriptiva en la que participaron 145 profesionales de 14 centros desalud de siete comunidades autónomas de España. El muestreo fue teórico. Se realizaron 14 grupos dediscusión. El análisis de datos se realizó siguiendo procedimientos del análisis de contenido temático y de acuerdo con siete modelos teóricos de promoción de la salud a nivel micro, meso y macro. Resultados: Las prácticas de los profesionales de los centros participantes en relación con las actividadesde prevención primaria y promoción de la salud se adhieren principalmente a modelos intrapersonales, centrándose en ayudar a que las personas se empoderen aumentando la conciencia de riesgo y de los beneficios del cambio en los comportamientos, y guiándolas en la implementación de un comportamientosaludable. Algunos/as profesionales realizan actividades que encajan en modelos interpersonales, implicando a la familia y al propio profesional en las estrategias. Solo en algunos casos las prácticas actualesencajan en modelos comunitarios de promoción de la salud. Conclusiones: Las prácticas de prevención primaria y promoción de la salud de los profesionales de atención primaria siguen principalmente modelos intrapersonales, en algunos casos modelos interpersonalesy más puntualmente modelos comunitarios. Es necesario potenciar la participación de la ciudadanía y laorientación comunitaria de los servicios de atención primaria de salud. Objective: To understand which theoretical models apply to current primary care practice of primary prevention and health promotion in a sample of primary health centres of seven autonomous regions in Spain according to the various professionals involved. Method: Descriptive qualitative research with the participation of 145 professionals from 14 primary health centres of seven autonomous regions in Spain. Theoretical sampling was used and 14 discussion groups were carried out. Data analysis followed thematic contents analysis procedures and was based on seven health promotion theoretical models at micro-, meso- and macro-level. Results: Current practice of primary prevention and health promotion activities mainly follow intrapersonal models, which focus on assisting the empowerment of patients by means of raising awareness of risk and benefits of behavioural change and on guiding the adoption of the new healthy behaviour. To a lesser degree, the activities of some professionals adhere to interpersonal models, which involve also the family and the health professional. In only a few instances community models of health promotion were used. Conclusions: Primary prevention and health promotion practice of primary healthcare professionals follow mainly intrapersonal models, few cases use interpersonal models and community models are only occasionally employed. Advance of public participation and community orientation in primary healthcare services is needed
