RESUMO

BACKGROUND AND AIMS: The association between changes in ultra-processed food (UPF) consumption and cardiometabolic risk (CMR) factors remains understudied. We evaluated the association between changes in UPF consumption over 12 months of follow-up and changes in CMR factors in adults diagnosed with metabolic syndrome. METHODS: We analysed data from 5373 adults (aged 55-75 years) participating in the PREDIMED-Plus trial. Diet was evaluated at baseline, 6- and 12-month visits using a validated food frequency questionnaire, and UPF consumption (in grams/day and percentage of total daily dietary intake in grams) was categorized based on NOVA classification. We used mixed-effects linear models with repeated measurements at baseline, 6 and 12 months of follow-up to assess the associations between changes in UPF consumption and changes in CMR factors adjusting for sociodemographic and lifestyles variables. RESULTS: In multivariable-adjusted models, when comparing the highest versus the lowest quartile of UPF consumption, positive associations were found for several CMR factors: weight (kg, ß = 1.09; 95% confidence interval 0.91 to 1.26); BMI (kg/m2, ß = 0.39; 0.33 to 0.46); waist circumference (cm, ß = 1.03; 0.81 to 1.26); diastolic blood pressure (mm Hg, ß = 0.67; 0.29 to 1.06); fasting blood glucose (mg/dl, ß = 1.66; 0.61 to 2.70); HbA1c (%, ß = 0.04; 0.01 to 0.07); triglycerides (mg/dl, ß = 6.79; 3.66 to 9.91) and triglycerides and glucose index (ß = 0.06; 0.04 to 0.08). CONCLUSIONS: Higher UPF consumption was associated with adverse evolution in objectively measured CMR factors after 12 months of follow-up in adults with metabolic syndrome. Further research is needed to explore whether these changes persist for longer periods.

RESUMO

Introduction: Type 2 diabetes has been linked to greater cognitive decline, but other glycemic parameters such as prediabetes, diabetes control and treatment, and HOMA-IR and HbA1c diabetes-related biomarkers have shown inconsistent results. Furthermore, there is limited research assessing these relationships in short-term studies. Thus, we aimed to examine 2-year associations between baseline diabetes/glycemic status and changes in cognitive function in older participants at high risk of cardiovascular disease. Methods: We conducted a 2-year prospective cohort study (n=6,874) within the framework of the PREDIMED-Plus study. The participants (with overweight/obesity and metabolic syndrome; mean age 64.9 years; 48.5% women) completed a battery of 8 cognitive tests, and a global cognitive function Z-score (GCF) was estimated. At baseline, participants were categorized by diabetes status (no-diabetes, prediabetes, and <5 or ≥5-year diabetes duration), and also by diabetes control. Furthermore, insulin resistance (HOMA-IR) and glycated hemoglobin (HbA1c) levels were measured, and antidiabetic medications were recorded. Linear and logistic regression models, adjusted by potential confounders, were fitted to assess associations between glycemic status and changes in cognitive function. Results: Prediabetes status was unrelated to cognitive decline. However, compared to participants without diabetes, those with ≥5-year diabetes duration had greater reductions in GCF (ß=-0.11 (95%CI -0.16;-0.06)], as well as in processing speed and executive function measurements. Inverse associations were observed between baseline HOMA-IR and changes in GCF [ß=-0.0094 (95%CI -0.0164;-0.0023)], but also between HbA1c levels and changes in GCF [ß=-0.0085 (95%CI -0.0115, -0.0055)], the Mini-Mental State Examination, and other executive function tests. Poor diabetes control was inversely associated with phonologic fluency. The use of insulin treatment was inversely related to cognitive function as measured by the GCF [ß=-0.31 (95%CI -0.44, -0.18)], and other cognitive tests. Conclusions: Insulin resistance, diabetes status, longer diabetes duration, poor glycemic control, and insulin treatment were associated with worsening cognitive function changes in the short term in a population at high cardiovascular risk.

RESUMO

Hiking is a very popular outdoor activity, and has led to an exponential increase in the number of visitors to natural spaces. The objective of this study was to analyze the circulation pattern of visitors to the Caminito del Rey trail, based on the three zones into which the trail can be divided. The sample consisted of 1582 hikers distributed into three different profiles. Of these, 126 utilized an eye-tracking device during the hike, while, for the rest (1456), only their travel speed along the trail was recorded. The use of eye tracking devices identified a greater number of interesting landscapes located in zones 1 and 3 of the trail, and it was observed that the mean travel speed was greater for zone 2 (42.31 m/min) (p < 0.01). Additionally, when the three different visitor profiles were analyzed, significant differences were found between the mean travel speeds according to sectors (p < 0.05). This information is crucial for more efficient management of the trail, as it allows for the development of measures to control and regulate the flow of visitors according to zone, and the design of additional strategies to increase the awareness of the hiker about specific areas of the hike.

RESUMO

Environmental and genetic factors are assumed to be necessary for the development of multiple sclerosis (MS), however its interactions are still unclear. For this reason here, we have not only analyzed the impact on increased risk of MS of the best known factors (HLA-DRB1*15:01 allele, sun exposure, vitamin D levels, smoking habit), but we have included another factor (skin phototype) that has not been analyzed in depth until now. This study included 149 MS patients and 147 controls. A multivariate logistic regression (LR) model was carried out to determine the impact of each of the factors on the increased risk of MS. Receiver Operating Characteristics (ROC) analysis was performed to evaluate predictive value of the models. Our multifactorial LR model of susceptibility showed that females with light brown skin (LBS), smokers and who had HLA-DRB1*15:01 allele had a higher MS risk (LBS: OR = 5.90, IC95% = 2.39-15.45; smoker: OR = 4.52, IC95% = 2.69-7.72; presence of HLA-DRB1*15:01: OR = 2.39, IC95% = 1.30-4.50; female: OR = 1.88, IC95% = 1.08-3.30). This model had an acceptable discriminant value with an Area Under a Curve AUC of 0.76 (0.69-0.82). Our study indicates that MS risk is determined by complex interactions between sex, environmental factors, and genotype where the milieu could provide the enabling proinflammatory environment that drives an autoimmune attack against myelin by self-reactive lymphocytes.

RESUMO

PURPOSE: Cardiovascular disease remains the global leading cause of death. We evaluated at baseline the association between the adherence to eight a priori high-quality dietary scores and the prevalence of individual and clustered cardiovascular risk factors (CVRF) in the PREDIMED-Plus cohort. METHODS: All PREDIMED-Plus participants (6874 men and women aged 55-75 years, with overweight/obesity and metabolic syndrome) were assessed. The prevalence of 4 CVRF (hypertension, obesity, diabetes, and dyslipidaemia), using standard diagnoses criteria, were considered as outcomes. The adherence to eight a priori-defined dietary indexes was calculated. Multivariable models were fitted to estimate differences in mean values of factors and prevalence ratios for individual and clustered CVRF. RESULTS: Highest conformity to any dietary pattern did not show inverse associations with hypertension. The modified Mediterranean Diet Score (PR = 0.95; 95% CI 0.90-0.99), Mediterranean Diet Adherence Score (MEDAS) (PR = 0.94; 95% CI 0.89-0.98), the pro-vegetarian dietary pattern (PR = 0.95; 95% CI 0.90-0.99) and the Alternate Healthy Eating Index 2010 (PR = 0.92; 95% CI 0.87-0.96) were inversely associated with prevalence of obesity. We identified significant inverse trend among participants who better adhered to the MEDAS and the Prime Diet Quality Score (PDQS) in the mean number of CVRF across categories of adherence. Better adherence to several high-quality dietary indexes was associated with better blood lipid profiles and anthropometric measures. CONCLUSIONS: Highest adherence to dietary quality indexes, especially Mediterranean-style and PDQS scores, showed marginal associations with lower prevalence of individual and clustered CVRF among elderly adults with metabolic syndrome at high risk of cardiovascular disease.

RESUMO

Background Telerehabilitation promises to improve quality, increase patient access and reduce costs in health care. Physiotherapy with exercises is generally recommended to restore function after surgery in patients with chronic subacromial syndrome. Relatively few studies have investigated the feasibility of telerehabilitation interventions in musculoskeletal and orthopaedic disorders. The aim of this study was to evaluate the feasibility and effectiveness of a customizable telerehabilitation intervention and compare with traditional care. Methods This research includes 18 consecutive patients with subacromial impingement who underwent arthroscopic subacromial decompression in a controlled clinical prospective study. Patients were randomized to either a 12-week telerehabilitation programme or the usual face-to-face physical therapy for immediate postoperative rehabilitation. We have developed a telerehabilitation system to provide services to patients who have undergone shoulder arthroscopy. An independent blinded observer performed postoperative follow-up after 4, 8, and 12 weeks. Results The preliminary efficacy of this telerehabilitation programme in terms of both physical and functional objective outcome measures was assessed on eight patients. Using the Constant-Murley score to evaluate functional outcome, patients in the telerehabilitation group were shown to have improved from a mean 43.50 ± 3.21 points to a mean 68.50 ± 0.86 points after 12 weeks. The physical and functional improvements in the telerehabilitation group were similar to those in the control group ( p = 0.213). There was a non-significant trend for greater improvements in the telerehabilitation group for most outcome measurements. Conclusion The results of this study provide evidence for the efficacy of telerehabilitation after shoulder arthroscopy in shoulder impingement syndrome. A telerehabilitation programme with range of motion, strengthening of the rotator cuff and scapula stabilizers exercises seems to be similar and not inferior to traditional face-to-face physiotherapy after subacromial arthroscopic decompression. Through this study, we are developing our preliminary dataset to evaluate the efficacy of telerehabilitation programmes following surgical procedures in musculoskeletal injuries and for comparison with more traditional interventions.

RESUMO

BACKGROUND: Educational institutions play an important role in encouraging student engagement, being necessary to know how engaged are students at university and if this factor is involved in student success point and followed.To explore the association between academic engagement and achievement. METHODS: Cross-sectional study. The sample consisted of 304 students of Health Sciences. They were asked to fill out an on-line questionnaire. Academic achievements were calculated using three types of measurement. RESULTS: Positive correlations were found in all cases. Grade point average was the academic rate most strongly associated with engagement dimensions and this association is different for male and female students. The independent variables could explain between 18.9 and 23.9% of the variance (p < 0.05) in the population of university students being analyzed. CONCLUSIONS: Engagement has been shown to be one of the many factors, which are positively involved, in the academic achievements of college students.

RESUMO

OBJECTIVES: To determine heart rate influence on voice fundamental frequency under stress conditions. METHODS: In 14 healthy volunteers, heart rate and blood pressure variables were analyzed during three classical autonomic tasks. Sustained voice samples were obtained to analyze F0. RESULTS: Cold pressure test increased mean blood pressure, without effect on heart rate; isometric and mental tasks increased heart rate and blood pressure. Voice F0 was only affected by mental and cold ice tasks; it significantly correlated with the heart rate that occurred before and during every vocal emission. DISCUSSION: Cardiovascular changes showed that subjects were significantly stressed during autonomic tasks. Heartbeat variations had a regular and significant influence on phonatory frequency, and this effect occurred during baseline and stress conditions.
