RESUMO
BACKGROUND: Gut microbiota and its by-products are increasingly recognized as having a decisive role in cardiovascular diseases. The aim is to study the relationship between gut microbiota and early vascular ageing (EVA). METHODS: A cross-sectional study was developed in Salamanca (Spain) in which 180 subjects aged 45-74 years were recruited. EVA was defined by the presence of at least one of the following: carotid-femoral pulse wave velocity (cf-PWV), cardio-ankle vascular index (CAVI) or brachial-ankle pulse wave velocity (ba-PWV) above the 90th percentile of the reference population. All other cases were considered normal vascular ageing (NVA). MEASUREMENTS: cf-PWV was measured by SphygmoCor® System; CAVI and ba-PWV were determined by Vasera 2000® device. Gut microbiome composition in faecal samples was determined by 16S rRNA Illumina sequencing. RESULTS: Mean age was 64.4 ± 6.9 in EVA group and 60.4 ± 7.6 years in NVA (p < .01). Women in EVA group were 41% and 53% in NVA. There were no differences in the overall composition of gut microbiota between the two groups when evaluating Firmicutes/Bacteriodetes ratio, alfa diversity (Shannon Index) and beta diversity (Bray-Curtis). Bilophila, Faecalibacterium sp.UBA1819 and Phocea, are increased in EVA group. While Cedecea, Lactococcus, Pseudomonas, Succiniclasticum and Dielma exist in lower abundance. In logistic regression analysis, Bilophila (OR: 1.71, 95% CI: 1.12-2.6, p = .013) remained significant. CONCLUSIONS: In the studied Spanish population, early vascular ageing is positively associated with gut microbiota abundance of the genus Bilophila. No relationship was found between phyla abundance and measures of diversity.

Background: In this study we analyzed the association between physical activity and sedentary lifestyle with vascular aging in Spanish populations aged 35-75 years. Methods: A cross-sectional study was developed, in which 501 subjects aged 35-75 years were recruited. Physical activity and sedentary time were measured with an accelerometer (Actigraph GTX3) for a week. We measured carotid-femoral pulse wave velocity (cfPWV) by a Sphygmo Cor® device and carotid intima-media thickness (cIMT) by ultrasound (Sonosite Micromax®). The vascular aging index (VAI) was calculated as described in the literature. Vascular aging was defined considering the 25th and 75th percentiles by age and sex of cfPWV and VAI, presence of vascular injury, type-2 diabetes mellitus or arterial hypertension. Individuals were classified into three groups: healthy, normal, and early vascular aging. Results: The mean age of the sample was 55.90 ± 14.24 years, 50% being women. Total physical activity was negatively associated with cfPWV ( ß = -0.454) and VAI ( ß = -1.845). Similarly, the number of steps per day obtained a negative association with cfPWV ( ß = -0.052) and VAI ( ß = -0.216), while sedentary time showed a positive association with cfPWV ( ß = 0.028) and VAI ( ß = 0.117). In the analysis by sex, the results showed similar values. The odds ratio (OR) of total physical activity of subjects classified as early vascular aging (EVA) with regarding those classified as healthy vascular aging (HVA) was 0.521 (95% confidence interval [CI] 0.317 to 0.856) for cfPWV, and 0.565 (95% CI 0.324 to 0.986) for VAI. In terms of the number of steps per day, the OR was 0.931 (95% CI 0.875 to 0.992) for cfPWV and 0.916 (95% CI 0.847 to 0.990) for VAI and for sedentary time the OR was 1.042 (95% CI 1.011 to 1.073) for cfPWV and 1.037 (95% CI 1.003 to 1.072) for VAI. The OR of subjects classified as vigorous physical activity was 0.196 (95% CI 0.041 to 0.941) using cfPWV and 0.161 (95% CI 0.032 to 0.820) using VAI. In the analysis by sex, the results showed an association in men when cfPWV was used and an association in women when VAI was used to define vascular aging. Conclusions: The results of this study indicate that the more time spent performing physical activity and the less sedentary time, the lower the arterial stiffness and the probability of developing early vascular aging. Clinical Trial Registration: The study was registered in ClinicalTrials.gov (number: NCT02623894).
RESUMO
The Research Network on Preventive Activities and Health Promotion (redIAPP), a reference network and promoter of primary care research was created in 2003 thanks to the program Thematic Networks for Cooperative Research in Health (RETICS) of the Instituto de Salud Carlos III (ISCIII). Its creation has meant a radical change in the situation of research in primary care. Throughout its 19 years (2003-2021), different research groups and autonomous communities have participated, and different lines of research have been developed with numerous projects and publications. Despite the difficulties suffered, it has created a collaborative research experience between different autonomous communities with great vitality and with important results for primary care. The redIAPP, therefore, has been a great reference for research in primary care and for the deepening of its area of knowledge. Several lines of improvement are suggested for the future of primary care research.
RESUMO
INTRODUCTION: The aim of this work was to analyse the association of the retinal arteriolar calibre and the arteriole/venule index (AV index) with vascular ageing in a general population without previous cardiovascular disease. MATERIALS AND METHODS: Descriptive cross-sectional study. A total of 482 individuals without cardiovascular disease (mean age: 55.6 ± 14.2 years) were selected by random sampling, stratified by age and sex. The retinal arteriolar calibre was measured using digital fundus images of the back of the eye captured with a validated, semiautomatized and computer-assisted software (Index calculator). Vascular ageing was defined using three criteria based on the values of: (1) Carotid-femoral Pulse Wave Velocity (cfPWV), (2) Brachial-ankle Pulse Wave Velocity (baPWV) and (3) Carotid Intima-Media Thickness. RESULTS: The AV index and arteriolar calibre show a negative correlation with age, arterial pressure, cardiovascular risk and parameters of vascular structure and function (p < 0.001 in all cases). We found lower mean values of the AV index and arteriolar calibre in the individuals with early vascular ageing compared to those with healthy vascular ageing. AV index was negatively correlated with cfPWV ((ß=-2.9; 95% CI (-4.7; -1.1)), baPWV ((ß=-3.2; 95% CI (-5.4; -0.9)) and vascular ageing index ((ß=-1.7; 95% CI (-2.7; -0.7)). Arteriolar calibre showed a negative correlation with baPWV (ß=-0.1; 95% CI (-0.2; -0.1)). In the logistic regression analysis, lower values of AV index ((OR=0.01; 95% CI (0.01-0.10), OR=0.03; 95% CI (0.01-0.11) and OR=0.09; 95% CI (0.01-0.67)) were associated with EVA defined with cfPWV, baPWV and vascular ageing index respectively, and lower values of arteriolar calibre ((OR=0.71; 95% CI (0.55-0.91)) were associated with EVA defined with vascular ageing index. CONCLUSIONS: Lower values of AV index and retinal arteriolar calibre were associated with vascular ageing in a general Spanish population without previous cardiovascular disease.

OBJECTIVES: The aim of this research was to evaluate the effects of adding 10â g of cocoa-rich chocolate (99%) to the habitual diet on cognitive performance in postmenopausal women. METHODS: Following a randomised controlled parallel clinical trial, a total of 140 postmenopausal women aged 50-64 were recruited. The intervention group (n = 73) consumed daily 10â g of chocolate (99% cocoa) in addition to their usual food intake for 6 months, whereas the control group (n = 67) did not receive any intervention. Attention and executive functions, verbal memory, working memory, phonological fluency, category fluency and clinical variables were assessed at baseline and 6 months. RESULTS: Trail Making Test B execution time showed a decreased of -12.08 s (95% CI: -23.99, -0.18; p = 0.047) in the intervention group compared to the control group, after adjusting for age, educational level, time elapsed from the beginning of menopause and daily energy consumption (Cohen's d = -0.343). Attention, immediate or delayed verbal memory, phonological or category fluency, and working memory remained unchanged. CONCLUSIONS: The consumption of cocoa-rich (99%) chocolate in addition to the habitual diet could be related to a slight improvement in cognitive performance regarding cognitive flexibility and processing speed in postmenopausal women, with no changes in the rest of the cognitive performance variables evaluated.Trial registration: This clinical trial has been registered at clinicaltrials.gov as NCT03492983.

BACKGROUND: The aim of this study was to assess the efficacy of the combined use of smartphone and smartband technology for 3-months alongside brief lifestyle counselling, versus counselling alone, in increasing physical activity. As secondary objectives, the effects of the intervention on dietary habits, body composition, quality of life, level of functionality and cognitive performance were assessed. METHODS: This study employed a randomized clinical trial of two-parallel groups design - control group (CG) and intervention group (IG). The study was conducted in 3 Spanish health-centres between October 2018-February 2020. Eligible participants were people of both sexes and aged between 65-80 years attending the health-centres with a score ≥ 24 points on the Mini-Mental State Examination. Key variables included physical activity, dietary pattern, body composition, cognitive performance, level of functionality and quality of life. All variables were measured at baseline and after 3-months. Both groups received a brief nutritional and physical activity advice. Intervention group participants were instructed to use a smartphone application for a period of 3-months. This application integrates information on physical activity received from a fitness bracelet and self-reported information on the patient's daily nutritional composition. RESULTS: The study population comprised 160 participants (IG = 81, CG = 79), with a mean age of 70.8 ± 4.0 years (61.3% women). No difference was found in the primary and secondary outcomes analyzed (physical activity (steps/min -0.4 (-1.0 to 0.2) p = 0.174), and dietary habits (Mediterranean diet score 0.0 (-0.6 to 0.6) p = 0.956) that could be attributed to either group after an ANCOVA test. A difference attributable to the intervention was observed in the total Clock test score (0.7 (0.1 to 1.2) p = 0.018. CONCLUSIONS: In a sample of people over 65 years of age, the combined use of the EVIDENT 3 smartphone app and an activity tracking bracelet for 3-months did not result in lifestyles changes related to the amount and level of physical activity or the eating habits, compared to brief lifestyle advice. Other clinical parameters were not changed either, although at the cognitive level, a slight improvement was observed in the score on the Clock test assessing a variety of cognitive functions such as memory. TRIAL REGISTRATION: The study was registered in ClinicalTrials.gov Identifier: NCT03574480. Date of trial Registration 02/07/2018.

BACKGROUND: The present study describes the effectiveness of a complex intervention that addresses multiple lifestyles to promote healthy behaviours in increasing adherence to the Mediterranean diet (MD). METHODS: Cluster-randomised, hybrid clinical trial controlled with two parallel groups. The study was carried out in 26 primary Spanish healthcare centres. People aged 45-75 years who presented at least two of the following criteria were included: smoker, low adherence to the MD or insufficient level of physical activity. The intervention group (IG) had three different levels of action: individual, group, and community, with the aim of acting on the behaviours related to smoking, diet and physical activity at the same time. The individual intervention included personalised recommendations and agreements on the objectives to attain. Group sessions were adapted to the context of each healthcare centre. The community intervention was focused on the social prescription of resources and activities performed in the environment of the community of each healthcare centre. Control group (CG) received brief advice given in the usual visits to the doctor's office. The primary outcome was the change, after 12 months, in the number of participants in each group with good adherence to the MD pattern. Secondary outcomes included the change in the total score of the MD adherence score (MEDAS) and the change in some cardiovascular risk factors. RESULTS: Three thousand sixty-two participants were included (IG = 1,481, CG = 1,581). Low adherence to the MD was present in 1,384 (93.5%) participants, of whom 1,233 initiated the intervention and conducted at least one individual visit with a healthcare professional. A greater increase (13.7%; 95% CI, 9.9-17.5; p < 0.001) was obtained by IG in the number of participants who reached 9 points or more (good adherence) in the MEDAS at the final visit. Moreover, the effect attributable to the intervention obtained a greater increase (0.50 points; 95% CI, 0.35 to 0.66; p < 0.001) in IG. CONCLUSIONS: A complex intervention modelled and carried out by primary healthcare professionals, within a real clinical healthcare context, achieved a global increase in the adherence to the MD compared to the brief advice. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03136211. Retrospectively registered on 02/05/2017 https://clinicaltrials.gov/ct2/show/NCT03136211.

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. TRIAL REGISTRATION: ClinicalTrials.gov NCT03175614; https://clinicaltrials.gov/ct2/show/NCT03175614.

BACKGROUND: Fever-7 is a test evaluating host mRNA expression levels of IFI27, JUP, LAX, HK3, TNIP1, GPAA1 and CTSB in blood able to detect viral infections. This test has been validated mostly in hospital settings. Here we have evaluated Fever-7 to identify the presence of respiratory viral infections in a Community Health Center. METHODS: A prospective study was conducted in the "Servicio de Urgencias de Atención Primaria" in Salamanca, Spain. Patients with clinical signs of respiratory infection and at least one point in the National Early Warning Score were recruited. Fever-7 mRNAs were profiled on a Nanostring nCounter® SPRINT instrument from blood collected upon patient enrolment. Viral diagnosis was performed on nasopharyngeal aspirates (NPAs) using the Biofire-RP2 panel. RESULTS: A respiratory virus was detected in the NPAs of 66 of the 100 patients enrolled. Median National Early Warning Score was 7 in the group with no virus detected and 6.5 in the group with a respiratory viral infection (P > .05). The Fever-7 score yielded an overall AUC of 0.81 to predict a positive viral syndromic test. The optimal operating point for the Fever-7 score yielded a sensitivity of 82% with a specificity of 71%. Multivariate analysis showed that Fever-7 was a robust marker of viral infection independently of age, sex, major comorbidities and disease severity at presentation (OR [CI95%], 3.73 [2.14-6.51], P < .001). CONCLUSIONS: Fever-7 is a promising host immune mRNA signature for the early identification of a respiratory viral infection in the community.

During menopause, women undergo a series of physiological changes that include a redistribution of fat tissue. This study was designed to investigate the effect of adding 10 g of cocoa-rich chocolate to the habitual diet of postmenopausal women daily on body composition. We conducted a 6-month, two-arm randomised, controlled trial. Postmenopausal women (57·2 (sd 3·6) years, n 132) were recruited in primary care clinics. Participants in the control group (CG) did not receive any intervention. Those of the intervention group (IG) received 10 g daily of 99 % cocoa chocolate in addition to their habitual diet for 6 months. This quantity comprises 247 kJ (59 kcal) and 65·4 mg of polyphenols. The primary outcomes were the between-group differences in body composition variables, measured by impendancemetry at the end of the study. The main effect of the intervention showed a favourable reduction in the IG with respect to the CG in body fat mass (-0·63 kg (95 % CI -1·15, -0·11), P = 0·019; Cohen's d = -0·450) and body fat percentage (-0·79 % (95 % CI -1·31, -0·26), P = 0·004; Cohen's d = -0·539). A non-significant decrease was also observed in BMI (-0·20 kg/m2 (95 % CI -0·44, 0·03), P = 0·092; Cohen's d = -0·345). Both the body fat mass and the body fat percentage showed a decrease in the IG for the three body segments analysed (trunk, arms and legs). Daily addition of 10 g of cocoa-rich chocolate to the habitual diet of postmenopausal women reduces their body fat mass and body fat percentage without modifying their weight.

BACKGROUND: During the transition to menopause, women experience different psychological, hormonal, and physical alterations that can affect their health. Physical activity is considered an important strategy in the prevention and control of such changes. AIM: To evaluate the short-term effect of an intensive intervention, based on a combined exercise programme using a Smartband, on the increase of physical activity and the decrease of sedentary lifestyle in postmenopausal and inactive women. DESIGN: Randomized clinical trial with two parallel groups. METHODS: In total, 100 postmenopausal and inactive women aged 45-70 years will be randomized to a control group or an intervention group. Both groups will be given a standardized advice about physical activity. The intervention group will carry out a supervised 12-week programme of aerobic and muscle strengthening exercise; moreover, the women in this group will receive a Smartband to assist them in the intervention. The main result will be the increase of physical activity and the decrease of sedentary lifestyle, measured with an accelerometer for 1 week. This programme will be conducted by a nurse and a physiotherapist of the health centre. The study was approved by the Drug Research Ethics Committee of the Salamanca Health Service on 15 February 2019. The project was funded by the Autonomous Government of Castile and Leon and by the Carlos III Health Institute. DISCUSSION: Physical activity is an important strategy to consider when addressing the changes caused by menopause, although the current evidence shows that further studies should be carried out with longer intervention periods and new technologies. IMPACT: This study will allow determining the effectiveness of the intensive intervention based on a combined programme of physical activity using a Smartband in postmenopausal and inactive women.

AIM: This study assesses the effect of an intervention to reduce the disruptive behaviours (DB) presented by care recipient users of adult day care centres (ADCC), thereby reducing caregiver overload. While ADCC offer beneficial respite for family caregivers, the DB that many care recipients show promote resistance to attending these centres, which can be a great burden on their family caregivers. DESIGN: Randomized controlled clinical trial. METHODS: The study was carried out with 130 family caregivers of people attending seven ADCC in the municipality of Salamanca (Spain), randomly distributed into intervention and control groups. The intervention was applied across eight sessions, one per week, in groups of 8-10 people where caregivers were trained in the Antecedent-Behavior-Consequence (ABC) model of functional behaviour analysis. The primary outcome was the reduction of DB measured with the Revised Memory and Behavior Problems Checklist (RMBPC). RESULTS: An average reduction in the RMBPC of 4.34 points was obtained in the intervention group after applying the intervention (p < 0.01 (U de Mann-Whitney); Cohen d = 1.00); furthermore, differences were found in the Center for Epidemiologic Studies Depression Scale (CES-D) (U = -2.67; p = 0.008; Cohen d = 0.50) and in the Short Zarit Burden Interview (Short ZBI) (t = -4.10; p < 0.01; Cohen d = 0.98). CONCLUSION: The results obtained suggest that the implementation of this intervention could reduce both the frequency of DB occurrence and the reaction of the caregiver to their appearance. Improvement was also noted in the results regarding overload and emotional state of the family caregiver. IMPACT: To our knowledge, this is the first randomized clinical trial to show that an intervention based on the ABC model could reduce the frequency and reaction of DB of care recipients in ADCC increasing their quality of life, and improving the mental health and overload of their family caregivers.

BACKGROUND: A more complete assessment of coronary artery disease (CAD) can be performed by coronary computed tomography angiography (CCTA). The aim was to assess the prevalence, distribution and characteristics of coronary artery disease (CAD) and the reclassification of cardiovascular risk by CCTA in an asymptomatic Spanish population. DESIGN: We included, in a cross-sectional study, 501 random subjects from asymptomatic population, aged 35 and 75. Risk factors, target organ damage and cardiovascular risk were assessed. CCTA was offered to measure the coronary artery calcium score(CACS), segment involvement score(SIS) and segment stenosis score(SSS). The offer was accepted by 220 subjects (44%), with a mean age of 58 ± 14 years, 56% of them male. RESULTS: The mean CACS was 119.6 ± 381.7 (median (IQR) (0 (0-61.55))), with higher scores in males (191.9 ± 493.1) than females (26.1 ± 73.3; P < .01). CCTA revealed coronary atherosclerosis in 89 cases, 40% (CI95%:34%-46%) in global, 51% in male and 25% in female, of which 13 had obstructive lesions (5.9%). Mean SIS was 1.5 ± 2.5 and SSS 1.2 ± 3.1. When the CACS was included in the CAD risk scale, there was a reclassification of 24%, and when using the SIS percentile, it was 38%, with a 9% increase in risk in both cases. CONCLUSIONS: The prevalence of CAD in asymptomatic Spanish population was 40%, with greater proportion among males. The incorporation of CACS and SIS in the assessment of cardiovascular risk allows reclassifying subjects who are at low or moderate risk and thus identify those with high cardiovascular risk and also the other way.

BACKGROUND: Controversy exists regarding the way alcohol use is associated with vascular structure and arterial stiffness parameters. The purpose of this study is to evaluate the association between alcohol consumption with vascular structure and arterial stiffness in an adult population. METHODS: We conducted a cross-sectional study. Five hundred and one participants were recruited by random sampling from an urban population of 43,946 individuals aged 35 to 75 years, assigned from 5 healthcare centers located in Salamanca, Spain. This was a subanalysis of the EVA study. Arterial stiffness was assessed by measuring cardio-ankle vascular index (CAVI) and brachial-ankle pulse wave velocity (ba-PWV) with the VaSera VS-1500® device, and carotid-femoral pulse wave velocity (cf-PWV) with the Sphygmocor® . Vascular structure was evaluated by measuring the carotid intima-media thickness (c-IMT) with a Sonosite Micromax® ultrasound. Alcohol consumption was calculated using a standardized questionnaire and quantified in g/wk. RESULTS: In the multiple regression analysis adjusted for sex, age, smoking status, and systolic blood pressure, the c-IMT and cf-PWV values of individuals drinking > 70 g/wk were higher than those of the reference group (nondrinkers) by 0.02 mm (p = 0.030) and 0.42 m/s (p = 0.021), respectively. The association between alcohol consumption with vascular structure and arterial stiffness only attains statistical significance for cf-PWV (p = 0.039) and c-IMT (p = 0.019), showing an association which suggests a J-shaped association. This association was not statistically significant for ba-PWV and CAVI (p = 0.446 and p = 0.141, respectively), although a similar trend was observed with ba-PWV. CONCLUSIONS: The results of this study suggest that heavy alcohol consumption (>70 g/wk) is associated with increased c-IMT and cf-PWV. Moreover, we found a J-shaped association between alcohol consumption and c-IMT and cf-PWV values as markers of vascular structure and arterial stiffness, with no association with ba-PWV and CAVI being observed.

Objective: To evaluate the postprandial effects of high and low glycaemic index (GI) breakfasts on cognitive performance in young, healthy adults.Methods: A crossover clinical trial including 40 young, healthy adults (aged 20-40 years, 50% females) recruited from primary healthcare centres in Salamanca, Spain. Verbal memory, phonological fluency, attention, and executive functions were examined 0, 60, and 120â minutes after consuming a low GI (LGI), high GI (HGI), or water breakfast. Every subject tried each breakfast variant, in a randomized order, separated by a washout period of 7 days, for a total of 3 weeks.Results: A significant interaction between the type of breakfast consumed and immediate verbal memory was identified (P<.05). We observed a trend towards better performance in verbal memory (delayed and immediate), attention, and phonological fluency following an LGI breakfast.Discussion: Cognitive performance during the postprandial phase in young, healthy adults was minimally affected by the GI of breakfast.

BACKGROUND: Daily aerobic exercise such as healthy walking could have an immediate effect on parameters of arterial stiffness; however, there is little evidence in the diabetic population. Our aim, therefore, is to evaluate the association between healthy walking and acute effects on the parameters of arterial stiffness in subjects with type 2 diabetes. METHODS: The Effectiveness of a multifactorial intervention in diabetics study (EMID), is a study based on an application for smartphones, healthy walking and a nutritional workshop in patients with type 2 diabetes in primary care, is a randomized controlled trial of two parallel groups. This is a subanalysis of the intervention group to evaluate the response to the healthy walking according to age and sex, in 89 subjects with type 2 diabetes, aged between 40 and 70 years. The intervention was a 4 km of a healthy walking at low-moderate intensity. To value our aim, the main study variables were measured before and after it. RESULTS: The study population had an average age of 65.0 years (61.2-68.1). After the healthy walking, there was a decrease in the parameters of arterial stiffness: Cardio ankle vascular index (CAVI) of - 0.2 (95%CI:-0.4 to - 0.1) and pulse pressure (PP) of the lower extremities of - 3.9 mmHg (95%CI: -5.9 to - 2.0). Furthermore, in the lower extremities there was a decrease in systolic blood pressure of - 5.3 mmHg (95% CI: -7.3 mmHg to - 3.3 mmHg), in diastolic blood pressure of - 1.5 mmHg (95% CI: -2.6 mmHg to - 0.4 mmHg) (p < 0.05 for all). It is observed that males have an OR of 2.981 (IC = 95% 1.095 to 8.119) to achieve a reduction in the CAVI (p < 0.05) and an OR of 2.433 (95%CI: 0.871 to 6.794) in the ankle PP (p > 0.05), compared with females. CONCLUSIONS: The findings of this study suggest that daily aerobic exercise at a low to moderate intensity, such as healthy walking, has an immediate beneficial effect on the cardio-ankle vascular index, especially in males.

BACKGROUND: The increasing use of smartphones by older adults also increases their potential for improving different aspects of health in this population. Some studies have shown promising results in the improvement of cognitive performance through lifestyle modification. All this may have a broad impact on the quality of life and carrying out daily living activities. The objective of this study is to evaluate the effectiveness of combining the use of smartphone and smartband technology for 3 months with brief counseling on life habits, as opposed to providing counseling only, in increasing physical activity and improving adherence to the Mediterranean diet. Secondary objectives are to assess the effect of the intervention on body composition, quality of life, independence in daily living activities and cognitive performance. METHODS: This study is a two-arm cluster-randomized trial that will be carried out in urban health centers in Spain. We will recruit 160 people aged between 65 and 80 without cardiovascular disease or cognitive impairment (score in the Mini-mental State Examination ≥24). On a visit to their center, intervention group participants will be instructed to use a smartphone application for a period of 3 months. This application integrates information on physical activity received from a fitness bracelet and self-reported information on the patient's daily nutritional composition. The primary outcome will be the change in the number of steps measured by accelerometer. Secondary variables will be adherence to the Mediterranean diet, sitting time, body composition, quality of life, independence in daily living activities and cognitive performance. All variables will be measured at baseline and on the assessment visit after 3 months. A telephone follow-up will be carried out at 6 months to collect self-reported data regarding physical activity and adherence to the Mediterranean diet. DISCUSSION: Preventive healthy aging programs should include health education with training in nutrition and lifestyles, while stressing the importance of and enhancing physical activity; the inclusion of new technologies can facilitate these goals. The EVIDENT-AGE study will incorporate a simple, accessible intervention with potential implementation in the care of older adults. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03574480 .

Paget´s disease of bone (PDB) is characterized by increased bone resorption followed by an excessive compensatory bone formation, with an abnormal bone structure with altered mechanical properties. Pagetic bone also has a higher vascularization and marrow fibrosis. Despite of pagetic bone being a highly vascularized tissue, there are no studies on the plasma levels of angiogenic mediators in the different states of the disease; moreover, the effect of PDB treatment on plasma levels of these angiogenic mediators is not very well known. The aim of this study was to analyse plasma levels of cytokines implicated in the increased bone turnover (OPG, RANKL, sclerostin) and hypervascularization (VEGF, PGF, ENG) observed in PDB and their evolution and response to zoledronic acid treatment in 70 PDB patients, 29 with an active disease measured by plasma alkaline phosphatase (ALP). Plasma ALP concentration was higher in active PDB than in inactive PDB patients, whereas there were no differences in OPG, RANKL, sclerostin, VEGF, PGF and ENG plasma levels between active and inactive PDB patients. ALP decreased at 3 and 12 months after zoledronic acid treatment. RANKL levels were reduced and sclerostin levels were increased after 12 months of treatment. PGF levels were lower 12 months after zoledronic acid treatment, whereas there were no differences in plasma VEGF and ENG after zoledronic acid treatment. Summarizing, zoledronic acid treatment is associated to decreases in plasma levels of ALP, RANKL, sclerostin and P1GF in active PDB patients. This treatment may reduce bone turnover and might reduce the pathological vascularisation typical of pagetic bone.

RESUMO
BACKGROUND: Health promotion is a key process of current health systems. Primary Health Care (PHC) is the ideal setting for health promotion but multifaceted barriers make its integration difficult in the usual care. The majority of the adult population engages two or more risk behaviours, that is why a multiple intervention might be more effective and efficient. The primary objectives are to evaluate the effectiveness, the cost-effectiveness and an implementation strategy of a complex multiple risk intervention to promote healthy behaviours in people between 45 to 75 years attended in PHC. METHODS: This study is a cluster randomised controlled hybrid type 2 trial with two parallel groups comparing a complex multiple risk behaviour intervention with usual care. It will be carried out in 26 PHC centres in Spain. The study focuses on people between 45 and 75 years who carry out two or more of the following unhealthy behaviours: tobacco use, low adherence to the Mediterranean dietary pattern or insufficient physical activity level. The intervention is based on the Transtheoretical Model and it will be made by physicians and nurses in the routine care of PHC practices according to the conceptual framework of the "5A's". It will have a maximum duration of 12 months and it will be carried out to three different levels (individual, group and community). Incremental cost per quality-adjusted life year gained measured by the tariffs of the EuroQol-5D questionnaire will be estimated. The implementation strategy is based on the "Consolidated Framework for Implementation Research", a set of discrete implementation strategies and an evaluation framework. DISCUSSION: EIRA study will determine the effectiveness and cost-effectiveness of a complex multiple risk intervention and will provide a better understanding of implementation processes of health promotion interventions in PHC setting. It may contribute to increase knowledge about the individual and structural barriers that affect implementation of these interventions and to quantify the contextual factors that moderate the effectiveness of implementation.
