RESUMO

AIM: To analyse recommended interventions for the safe and responsible dissemination of suicidal behaviour in the media for preventive purposes. BACKGROUND: Suicide is a serious public health problem that leads to more than 700,000 deaths per year, which translates into one death every forty seconds. The media play a significant role in shaping public perceptions and reflecting societal issues. Because of its active role in the construction of reality, the way in which the media report and expose suicidal behaviour has the capacity to influence the population in either a preventive or harmful way. DESIGN: An umbrella review was carried out and a report was written according to the Preferred Reporting Items for Overviews of Reviews. METHODS: We systematically searched for reviews published from inception to February 2023 in MEDLINE (PubMed), CINAHL and PsycInfo (via EBSCOhost), Web of Science, Embase, Cochrane Library of Systematic Reviews, Scopus, and Google Scholar. A narrative synthesis of the results was conducted. RESULTS: Six systematic reviews with a moderate to high quality level were selected. Among the recommended interventions were the inclusion of positive messages of hope, resilience, or of overcoming the event, narratives with information on available resources or the promotion of support-seeking attitudes as an effective prevention mechanism, as well as the avoidance of repetitive reporting of the same suicide. The appropriate and responsible dissemination of information on suicidal behaviour in the media with complete and up-to-date information on available centres, organisations, institutions, and resources has proven to be effective, especially in vulnerable populations. CONCLUSION: Educating and training the media in an appropriate approach to disseminating suicidal behaviour helps to reduce the number of suicidal behaviours. Knowing what information is advisable to include in the news item as well as what information to avoid is a strong point. Guidelines to promote responsible media reporting are a key component of suicide prevention strategies. This study was prospectively registered in the International Prospective Register of Systematic Reviews (PROSPERO) on 23 April 2022 with the registration number CRD42022320393.

RESUMO

The objective of this study was to evaluate the effects of consuming 50 g of raisins on cognitive performance, quality of life, and functional activities in healthy older adults. This is a parallel randomized controlled clinical trial, in which 80 subjects over 70 years of age participated. For 6 months, the intervention group (IG; n = 40) consumed 50 g of raisins per day added to their usual diet, whereas the control group (CG; n = 40) received no supplement. All variables were measured at baseline and at 6 months. Cognitive performance assessed with the Montreal Cognitive Assessment (MOCA) test shows a difference of 3.27 points (95% CI 1.59 to 4.96), p ≤ 0.001, favorable to the IG, after the intervention. Among the cognitive performances, an improvement is observed in the IG in orientation, assessed both with the MOCA test 0.49 (95% CI 0.10 to 0.87), p = 0.014, and with the Mini-Mental State Examination (MMSE) test, 0.36 (95% CI 0.02 to 0.70), p = 0.038. In visuospatial/executive capacity and in language, improvements were also observed in the IG, 1.36 (95% CI 0.77 to 1.95), p = 0.001, and 0.54 points (95% CI 0.12 to 0.96), p = 0.014, respectively. Immediate and delayed recall, assessed with the Rey Auditory Verbal Learning Test, improved in the IG. In addition, the IG showed a better quality of life and greater autonomy in instrumental activities of daily living after 6 months. No significant changes were observed in the rest of the variables analyzed. Therefore, the consumption of 50 g of raisins produces a slight improvement in cognitive performance, quality of life, and functional activities in the elderly.

RESUMO

Polyphenols have been shown to be effective against many chronic diseases. These compounds could have a beneficial effect at the cognitive level. The exact mechanism by which they provide positive effects at the cognitive level is not well known, but it is believed that they could counteract neuroinflammation. The objective of this study is to review nutritional interventions that include foods or supplements rich in flavanols, flavonols, or stilbenes to the usual diet on cognitive deterioration in people over 50 years of age. Clinical trials published in PubMed and Web of Science from 1 March 2010 to 1 March 2020 were explored, from which 14 studies were selected. All of them showed some improvement after the intervention. In interventions with flavanols and stilbenes, relevant improvements have been observed both in healthy patients and in patients with established cognitive impairment. Most studies agree that the greatest benefits are found with high doses and longer duration treatments. The changes were fundamentally assessed through cognitive tests, and in some of the studies, through magnetic resonance imaging (fMRI). The type of cognitive test used to assess the effect of the intervention was revealed to be critical. Several studies have also shown improvements in analytical parameters and blood pressure.

RESUMO

As shown in the previous literature, in view of the future responsibilities of nursing professionals and the consequences for healthcare, it is of great interest to examine their risk perceptions, coping behaviors, and sense of coherency during the COVID-19 pandemic. The purpose of this study is to design and to validate a specific questionnaire that evaluates the factors relating to perceived risk, coping behaviors, and preventive knowledge against COVID-19 infection among nursing students from Spain. This is a psychometric study of a questionnaire's design and its validation in 1562 nursing students at 16 undergraduate nursing institutions in Spain. An ad-hoc survey was designed by a panel of six experts drawing from the literature. After a trial test, the questionnaire was formed with four scales (perception, risk, coping, and knowledge of preventive practices for COVID-19), with a total of 69 items. The final questionnaire was composed of 52 items grouped into four scales, with good psychometric properties to measure risk perception (Cronbach's alpha 0.735), factors related to perceived risk (Cronbach's alpha 0.653), coping behaviors (Cronbach's alpha 0.80), and knowledge of preventive practices against COVID-19 (Cronbach's alpha 0.77). This questionnaire, specifically designed and validated for nursing students, is the first to address four important areas in the development of preventive measures against COVID-19.

RESUMO

BACKGROUND: The increase in the survival of oncology patients include multiple side effects as cancer-related asthenia and dyspnea, which represents a serious health problem. An implementation of the conventional clinical practice, developed through multimodal physical exercise and functional rehabilitation program intervention, may be useful in controlling dyspnoea. This study aims to evaluate the effects of a multimodal exercise and functional rehabilitation program on fatigue, pain, functional capacity, and quality of life in cancer patients with cancer-related asthenia. METHODS: This is a protocol for an experimental, prospective, randomised study using a parallel, fixed assignment scheme, with an experimental group and a control group in patients from the oncology hospitalisation unit at the Salamanca University Hospital Complex in Spain, using consecutive sampling to select 50 participants with oncological asthenia who are hospitalised at the time of inclusion. After the baseline evaluation, the participants will be randomised into two groups. Both groups will receive standard clinical practice care and the normal health education program at discharge, but in addition, the participants assigned to the experimental group will also complete a multimodal exercise and functional rehabilitation program lasting one month. The primary outcomes will be basic activities of daily living (Barthel Index) and degree of asthenia (FACT-An scale). Additionally, physical performance will be evaluated with the Short Physical Performance Battery (SPPB), as will the attention and executive functions (Trail-Making Test), fear/avoidance of movement (TAMPA scale), pain (VAS scale), and body composition (waist, hip, brachial, thigh, wrist, and ankle circumferences). DISCUSSION: The results of this study may be translated to clinical practice, incorporating a specific autonomy recovery programme into comprehensive rehabilitation programmes of care for cancer patients with asthenia. The current study addresses to improve the conventional clinical practice by proposing a multimodal physical exercise and functional rehabilitation program intervention, which will be implemented by an interdisciplinary team, to try to improve the autonomy of cancer patients with cancer-related asthenia.

RESUMO

BACKGROUND: The relationship between the quality of the diet and the adherence to the Mediterranean diet with the presence of persistent or recurrent depressive symptoms have been described. The objective of this study is to analyze the relationship between adherence to the Mediterranean diet and the intake of specific foods in primary care patients aged 45 to 75, having subclinical or major depression. The study also specifically analyzes this relationship in individuals suffering from chronic diseases. METHODS: A cross-sectional descriptive study was conducted. 3062 subjects met the inclusion criteria from the EIRA study. Sociodemographic variables, clinical morbidity, depression symptomatology (PHQ-9) and adherence to Mediterranean diet (MEDAS) were collected. RESULTS: Being female, younger, with a higher BMI, consuming more than 1 serving of red meat a day and drinking more than one carbonated or sugary drink daily, not consuming 3 servings of nuts a week and not eating 2 vegetables cooked in olive oil a week are predictors of having higher depressive symptomatology. CONCLUSIONS: Assessing the type of diet of patients presenting depressive symptoms and promoting adherence to a healthy diet is important, especially in patients with chronic diseases. However, depression is a very complex issue and the relationship between nutrition and depression must be further examined.

RESUMO

BACKGROUND: Survival in cancer patients has increased exponentially in recent years, with multiple side effects caused by treatments. Cancer-related asthenia and dyspnea are among them, which represent a serious health problem, with considerable limitations and reduced quality of life. An implementation of the conventional clinical practice, developed through physical exercise, may be useful in controlling dyspnoea. This study aims to compare the effects of a comprehensive rehabilitation implementing a programme of multimodal physical exercise with a specific autonomy recovery programme, versus an isolated intervention using the physical exercise programme alone, on the functionality, physical performance and respiratory parameters in oncologycal patients with dyspnea. METHODS: This is a protocol por an experimental, prospective, randomized, parallel-controlled clinical trial, with two arms design of fixed assignment with an experimental and control groups. It will conduct in the Oncology Hospitalisation Unit at the University Hospital Complex of Salamanca, using consecutive sampling to select 50 participants with oncological dyspnoea who are hospitalised at the time of inclusion. After baseline assessment, participants will be randomised into the groups. Experimental group will complete Comprehensive Rehabilitation with the autonomy recovery and the multimodal exercise programmes, and in the control group, only the multimodal exercise programme will be carried out. The primary outcomes will be basic activities of daily living (Barthel Index) and degree of dyspnoea (MRC scale). Additionally, physical performance will be evaluated with the Short Physical Performance Battery (SPPB), as will the oxygen saturation in the blood using pulse oximetry, fear/avoidance of movement with the Tampa Scale of Kinesiophobia (TSK), and the quality of life of the oncology patient (ECOG performance scale). DISCUSSION: The results of this study may be translated to clinical practice, incorporating a specific autonomy recovery programme into comprehensive rehabilitation programmes of care for cancer patients with dyspnoea. Increase in the survival of patients with cancer includes multiple side effects as cancer-related asthenia and dyspnea, which represents a serious health problem. The current study addresses to improve the conventional clinical practice by proposing an integral, rehabilitative approach, to implement education and training for oncology patients with dyspnea to increase their quality of life.

RESUMO

BACKGROUND: Information and communication technologies are currently among the supporting elements that may contribute to improving health and changing lifestyles. OBJECTIVE: The aim of this study was to evaluate the long-term effectiveness of adding an app to standardized counseling in order to increase physical activity (PA) and adherence to the Mediterranean diet and to analyze the effects of app adherence in lifestyle changes. METHODS: A randomized, multicenter clinical trial with a 12 month-follow up was conducted, involving 833 participants recruited by random sampling in 6 primary Spanish care centers (415 vs 418). Counseling on PA and the Mediterranean diet was given to both groups by a research nurse; however, the counseling + app group (intervention group) received additional training in the use of an app that was designed to promote the Mediterranean diet and PA over a 3-month period. Main outcomes and measures included PA by accelerometer and the 7-day Physical Activity Recall (PAR) questionnaire and adherence to the Mediterranean diet by an adherence screener questionnaire. We considered adherence to the app to be high when it was used for more than 60 days. RESULTS: The mean age was 51 years (SD 12) in the intervention group and 52.3 years (SD 12.0) in the counseling-only group; females predominated in both groups (60.0%, 249/415 and 64.1%, 268/418, respectively). PA by accelerometer declined in both groups at 12 months (P value for tendency in moderate to vigorous PA, [MVPA]=.15). The intervention subgroup with high app adherence had better behavior than the low adherence subgroup (P value for tendency in MVPA=.001). PA analyzed by 7-day PAR did not show changes at 12 months in any of the groups (P value for tendency=.25). In the Mediterranean diet, an increase in adherence was observed in both groups at 12 months with no differences between them (P value for tendency=.46). In these two cases, the group with high app adherence also had better behavior, although without reaching significance for the tendency (P>.05). CONCLUSIONS: The participants with strongest app adherence showed better outcomes in terms of maintenance of healthy lifestyles at 12 months than those with weaker adherence. Overall, however, we found no differences between intervention group and counseling-only group in PA increase and adherence to the Mediterranean diet in the long term.

RESUMO

BACKGROUND: Studies concerning ideal cardiovascular (CV) health and its relationship with arterial stiffness are lacking. This study examined the association between arterial stiffness with ideal CV health as defined by the American Heart Association, across age groups and gender. METHODS: The cross-sectional study included 1365 adults. Ideal CV health was defined as meeting ideal levels of the following components: 4 behaviors (smoking, body mass index, physical activity, and Mediterranean diet adherence) and 3 factors (total cholesterol, blood pressure, and glycated hemoglobin). Patients were grouped into 3 categories according to their number of ideal CV health metrics: ideal (5-7 metrics), intermediate (3-4 metrics), and poor (0-2 metrics). We analyzed the pulse wave velocity (PWV), the central and radial augmentation indexes, and the ambulatory arterial stiffness index (AASI). RESULTS: The ideal CV health profile was inversely associated with lower arterial radial augmentation index and AASI in both genders, particularly in middle-aged (45-65 years) and in elderly subjects (>65 years). Also in elderly subjects, adjusted models showed that adults with at least 3 health metrics at ideal levels had significantly lower PWV than those with 2 or fewer ideal health metrics. CONCLUSIONS: An association was found between a favorable level of ideal CV health metrics and lower arterial stiffness across age groups.

RESUMO

Objetivo: Examinar, en una población no diabética, si la asociación entre la rigidez arterial y los niveles glucémicos depende de la prueba utilizada como indicador glucémico, glucosa en ayunas o hemoglobina glicosilada A1c (HbA1c). Población de pacientes y métodos: Análisis transversal de una submuestra de 220 no diabéticos del estudio EVIDENT II en el que se determinaron los parámetros relacionados con glucosa en ayunas, HbA1c y rigidez arterial (velocidad de onda de pulso, índice de aumento radial y central y presión de pulso central). Las diferencias de medias entre los parámetros relacionados con la rigidez arterial en cada tercil de HbA1c y glucosa en ayunas se determinaron mediante un análisis de covarianza. Resultados: La media de todos los parámetros de rigidez arterial aumentaba por cada tercil de HbA1c, aunque las diferencias de medias solamente fueron estadísticamente significativas para la velocidad de la onda de pulso (p < 0,001), incluso tras ajustar por los potenciales factores de confusión (HbA1c <5,3% = 6,88 m/s; HbA1c 5,3%-5,59% = 7,06 m/s; y HbA1c 5,6% = 8,16 m/s, p = 0,004). Por el contrario, las diferencias de medias en la velocidad de onda de pulso por terciles de glucosa en ayunas no mostraron diferencias estadísticamente significativas después de ajustar por estos factores de confusión (glucosa 4,44 mmol/l = 7,18 m/s; glucosa 4,44 mmol/l-4,87 mmol/l= 7,26 m/s; y glucosa ≥4,88 mmol/l= 7.93 m/s, p = 0,066). Conclusiones: Los niveles de glucosa en la población no diabética se asociaron a rigidez arterial, aunque de forma más estrecha cuando esos niveles se determinaron usando HbA1c (AU)


Objective: To examine, in a non-diabetic population, whether the association between arterial stiffness and glycaemic levels depends on the test used as a glycaemic indicator, fasting plasma glucose (FPG) or glycated haemoglobin A1c (HbA1c). Patient population and methods: A cross-sectional analysis of a 220 non-diabetic subsample from the EVIDENT II study in which FPG, HbA1c and arterial stiffness-related parameters (pulse wave velocity, radial and central augmentation index, and central pulse pressure) were determined. Mean differences in arterial stiffness-related parameters by HbA1c and FPG tertiles were tested using analysis of covariance. Results: All means of arterial stiffness-related parameters increased by HbA1c tertiles, although mean differences were only statistically significant in pulse wave velocity (p ≤.001), even after controlling for potential confounders (HbA1c <5.30% = 6.88 m/s; HbA1c 5.30%-5.59% = 7.06 m/s; and HbA1c ≥5.60% = 8.16 m/s, p =.004). Conversely, mean differences in pulse wave velocity by FPG tertiles did not reach statistically significant differences after controlling for potential confounders (FPG 4.44 mmol/l = 7.18 m/s; FPG 4.44 mmol/l-4.87 mmol/l = 7.26 m/s; and FPG ≥4.88 mmol/l = 7.93 m/s, p =.066). Conclusions: Glucose levels in a non-diabetic population were associated with arterial stiffness but better when levels were determined using HbA1c (AU)

RESUMO

OBJECTIVES: We prospectively examined the impact of type 2 diabetes compared with metabolic syndrome (MetS) on the development of vascular disease over 4 years as determined by anatomic and functional markers of vascular disease. By comparing the vascular outcomes of the 2 disorders, we seek to determine the independent effect of elevated glucose levels on vascular disease. SETTING: 2 primary care centres in Salamanca, Spain. PARTICIPANTS: We performed a prospective observational study involving 112 patients (68 with type 2 diabetes and 44 with MetS) who were followed for 4 years. PRIMARY AND SECONDARY OUTCOME MEASURES: Measurements included blood pressure, blood glucose, lipids, smoking, body mass index, waist circumference, Homeostasis Model Assessment Insulin Resistance (HOMA-IR), hs-c-reactive protein and fibrinogen levels. We also evaluated vascular, carotid intima media thickness (IMT), pulse wave velocity (PWV) and ankle/brachial index, heart and renal target organ damage (TOD). The haemodynamic parameters were central (CAIx) and peripheral (PAIx) augmentation indices. RESULTS: In year 4, participants with type 2 diabetes had increased IMT thickness. These patients had more plaques and an IMT>0.90 mm. In participants with MetS, we only found an increase in the number of plaques. We found no changes in PWV, CAIx and PAIx. The patients with diabetes had a greater frequency of vascular TOD. There were no differences neither in renal nor cardiac percentage of TOD in the patients with MetS or diabetes mellitus type 2. CONCLUSIONS: This prospective study showed that the evolution of vascular TOD is different in participants with type 2 diabetes compared with those with MetS. While IMT and PWV increased in type 2 diabetes, these were not modified in MetS. The renal and cardiac TOD evolution, as well as the PAIx and CAIx, did not change in either group.

RESUMO

BACKGROUND: The purpose of this study was to analyze the evolution of vascular, cardiac and renal target organ damage (TOD) in patients with increased insulin resistance over a 3.5 year follow-up and to investigate gender difference and factors that influence its progression. METHODS: We performed a prospective observational study involving 112 patients (71 men, 41 women) who were followed for 3.5 years. Measurements included blood pressure, blood glucose, lipids, smoking, body mass index (BMI) and HOMA-Ir Vascular TOD included carotid intima-media thickness (IMT), pulse wave velocity (PWV) and ankle/brachial index (ABI). Cardiac TOD included Cornell voltage-duration product and Sokolow. Renal TOD included creatinine, glomerular filtration and albumin/creatinine ratio. RESULTS: The IMT increased in both genders. Each year, the IMT increased 0.005 mm in men and 0.011 in women and the PWV 0.024 and 0.020 m/sec, respectively. The highest increase was in women with type 2 diabetes mellitus, who had an increase in TOD carotid (40%), PWV (24%) and renal TOD (20 %). Multiple regression analysis, after adjusting for age and gender, showed a negative association between duration since diabetes diagnosis and ABI (ß = -0.006; p = 0.017) and between BMI and glomerular filtration (ß = -0.813; p = 0.014). HbA1c was positively associated with PWV (ß = 0.501; p = 0.014). CONCLUSIONS: This study showed that the progression of vascular and renal TOD differs by gender. The increase in vascular and renal TOD was higher in women, especially in diabetic women. The PWV increase showed a positive association with mean HbA1c levels during the follow-up. Glomerular filtration was associated with BMI and the ABI was associated with duration since type 2 diabetes mellitus diagnosis. TRIAL REGISTRATION: Clinical Trials.gov Identifier NCT01065155.

RESUMO

OBJECTIVES: The use of brief screening tools to identify inactive patients is essential to improve the efficiency of primary care-based physical activity (PA) programs. However, the current employment of short PA questionnaires within the Spanish primary care pathway is unclear. This study evaluated the validity of the Spanish version of a Brief Physical Activity Assessment Tool (SBPAAT). METHODS: A validation study was carried out within the EVIDENT project. A convenience sample of patients (n = 1,184; age 58.9±13.7 years; 60.5% female) completed the SBPAAT and the 7-day Physical Activity Recall (7DPAR) and, in addition, wore an accelerometer (ActiGraph GT3X) for seven consecutive days. Validity was evaluated by measuring agreement, Kappa correlation coefficients, sensitivity and specificity in achieving current PA recommendations with the 7DPAR. Pearson correlation coefficients with the number of daily minutes engaged in moderate and vigorous intensity PA according to the accelerometer were also assessed. Comparison with accelerometer counts, daily minutes engaged in sedentary, light, moderate, and vigorous intensity PA, total daily kilocalories, and total PA and leisure time expenditure (METs-hour-week) between the sufficiently and insufficiently active groups identified by SBPAAT were reported. RESULTS: The SBPAAT identified 41.3% sufficiently active (n = 489) and 58.7% insufficiently active (n = 695) patients; it showed moderate validity (k = 0.454, 95% CI: 0.402-0.505) and a specificity and sensitivity of 74.3% and 74.6%, respectively. Validity was fair for identifying daily minutes engaged in moderate (r = 0.215, 95% CI:0.156 to 0.272) and vigorous PA (r = 0.282, 95% CI:0.165 to 0.391). Insufficiently active patients according to the SBPAAT significantly reported fewer counts/minute (-22%), fewer minutes/day of moderate (-11.38) and vigorous PA (-2.69), spent fewer total kilocalories/day (-753), and reported a lower energy cost (METs-hour-week) of physical activities globally (-26.82) and during leisure time (-19.62). CONCLUSIONS: The SBPAAT is a valid tool to identify Spanish-speaking patients who are insufficiently active to achieve health benefits.

RESUMO

BACKGROUND: The cardio ankle vascular index (CAVI) is a new index of the overall stiffness of the artery from the origin of the aorta to the ankle. This index can estimate the risk of atherosclerosis. We aimed to find the relationship between CAVI and target organ damage (TOD), vascular structure and function, and cardiovascular risk factors in Caucasian patients with type 2 diabetes mellitus or metabolic syndrome. METHODS: We included 110 subjects from the LOD-Diabetes study, whose mean age was 61 ± 11 years, and 37.3% were women. Measurements of CAVI, brachial ankle pulse wave velocity (ba-PWV), and ankle brachial index (ABI) were taken using the VaSera device. Cardiovascular risk factors, renal function by creatinine, glomerular filtration rate, and albumin creatinine index were also obtained, as well as cardiac TOD with ECG and vascular TOD and carotid intima media thickness (IMT), carotid femoral PWV (cf-PWV), and the central and peripheral augmentation index (CAIx and PAIx). The Framingham-D'Agostino scale was used to measure cardiovascular risk. RESULTS: Mean CAVI was 8.7 ± 1.3. More than half (54%) of the participants showed one or more TOD (10% cardiac, 13% renal; 48% vascular), and 13% had ba-PWV ≥ 17.5 m/s. Patients with any TOD had the highest CAVI values: 1.15 (CI 95% 0.70 to 1.61, p < 0.001) and 1.14 (CI 95% 0.68 to 1.60, p < 0.001) when vascular TOD was presented, and 1.30 (CI 95% 0.51 to 2.10, p = 0.002) for the cardiac TOD. The CAVI values had a positive correlation with HbA1c and systolic and diastolic blood pressure, and a negative correlation with waist circumference and body mass index. The positive correlations of CAVI with IMT (ß = 0.29; p < 0.01), cf-PWV (ß = 0.83; p < 0.01), ba-PWV (ß = 2.12; p < 0.01), CAIx (ß = 3.42; p < 0.01), and PAIx (ß = 5.05; p = 0.04) remained after adjustment for cardiovascular risk, body mass index, and antihypertensive, lipid-lowering, and antidiabetic drugs. CONCLUSIONS: The results of this study suggest that the CAVI is positively associated with IMT, cf-PWV, ba-PWV, CAIx, and PAIx, regardless of cardiovascular risk and the drug treatment used. Patients with cardiovascular TOD have higher values of CAVI. TRIAL REGISTRATION: Clinical Trials.gov Identifier: NCT01065155.

RESUMO

OBJECTIVE: The aim of this study was to analyze the association between sedentary behaviour, as assessed by an accelerometer, and mean carotid intima-media thickness (IMT). METHODS: The study included 263 healthy subjects belonging to the EVIDENT study (59.3% women). Carotid IMT was measured by carotid ultrasonography. Sedentary behaviour was measured objectively over 7 days using ActiGraph accelerometers. Thresholds of 10 consecutive minutes were used to establish sedentary bouts, and assess the number (n/day), and length ≥10 min (min/day). RESULTS: Total sedentary time and sedentary time in bouts ≥10 min was higher in participants with a larger mean carotid IMT (>P75). Otherwise, this sedentary time in bouts ≥10 min parameter was weakly associated with augmented carotid IMT injury in the logistic regression model. CONCLUSION: Total sedentary time and sedentary time in bouts ≥10 min, as assessed by accelerometer, was positively but weakly associated with carotid IMT. Equally, this sedentary time in bouts ≥10 min was associated with carotid injury, but disappears after adjusting for potential confounders. These findings support that reducing sedentary time and increasing breaks in bouts of sedentary time might represent a useful additional strategy in the cardiovascular disease prevention.

RESUMO

BACKGROUND: To analyze the relationship of cocoa intake to central and peripheral blood pressure, arterial stiffness, and carotid intima-media thickness in subjects with some cardiovascular risk factor. DESIGN: A cross-sectional study of 351 subjects (mean age 54.76 years, 62.4% males). MEASUREMENTS: Intake of cocoa and other foods using a food frequency questionnaire, central and peripheral (ambulatory and office) blood pressure, central and peripheral augmentation index, pulse wave velocity, ambulatory arterial stiffness index, carotid intima-media thickness, and ankle-brachial index. RESULTS: Higher pulse wave velocity and greater cardiovascular risk were found in non-cocoa consumers as compared to high consumers (p < 0.05). In a multivariate analysis, these differences disappeared after adjusting for age, gender, the presence of diabetes, systolic blood pressure and antihypertensive and lipid-lowering drug use. All other arterial stiffness measures (central and peripheral augmentation index, ambulatory arterial stiffness index, ankle-brachial index, and carotid intima-media thickness) showed no differences between the different consumption groups. CONCLUSIONS: In subjects with some cardiovascular risk factors, cocoa consumption does not imply improvement in the arterial stiffness values.

RESUMO

BACKGROUND: The present study was designed to evaluate which arterial stiffness parameter - AASI or the home arterial stiffness index (HASI) - correlates best with vascular, cardiac and renal damage in hypertensive individuals. METHODS: A cross-sectional study was carried out involving 258 hypertensive patients. AASI and HASI were defined as the 1-regression slope of diastolic over systolic blood pressure readings obtained from 24-hour recordings and home blood pressure over 6 days. Renal damage was evaluated by glomerular filtration rate (GFR) and microalbuminuria; vascular damage by carotid intima-media thickness (IMT), pulse wave velocity (PWV) and ankle/brachial index (ABI); and left ventricular hypertrophy by the Cornell voltage-duration product (VDP) and the Novacode index. RESULTS: AASI and HASI were not correlated with microalbuminuria, however AASI and HASI- blood pressure variability ratio (BPVR) showed negative correlation with GRF. The Cornell PDV was positively correlated with AASI- BPVR-Sleep (r = 0.15, p < 0.05) and the left ventricular mass index with HASI-BPVR (r = 0.19, p < 0.01). Carotid IMT and PWV were positively correlated with all the parameters except the HASI, while ABI was negatively correlated with AASI and Awake-AASI. After adjusting for age, gender and 24 hours heart rate, statistical significance remains of the IMT with AASI, Awake AASI and AASI-BPVR. PWV with the AASI, Awake-AASI and Sleep-AASI. ABI with AASI and Awake-AASI. Odd Ratio to presence target organ damage was for AASI: 10.47(IC95% 1.29 to 65.34), Awake-AASI: 8.85(IC95% 1.10 to 71.04), Sleep-AASI: 2.19(IC95% 1.10 to 4.38) and AASI-BPVR-night: 4.09 (IC95% 1.12 to 14.92). CONCLUSIONS: After adjusting for age, gender and 24-hour heart, the variables that best associated with the variability of IMT, PWV and ABI were AASI and Awake-AASI, and with GFR was HASI-BPVR.

RESUMO

BACKGROUND: We examined the relationship between the intima-media thickness of the common carotid artery (CCA-IMT) and arterial stiffness, assessed by pulse wave velocity (PWV), the ambulatory arterial stiffness index (AASI) and the augmentation index (AIx) in subjects with and without type 2 diabetes. METHODS: A case-series study was made in 366 patients (105 diabetics and 261-non-diabetics). Ambulatory blood pressure monitoring was performed on a day of standard activity with the SpaceLabs 90207 system. AASI was calculated as "1-slope" from the within-person regression of diastolic-on-systolic ambulatory blood pressure readings. PWV and AIx were measured with the SphygmoCor system, and a Sonosite Micromax ultrasound unit was used for automatic measurements of CCA-IMT. RESULTS: PWV, AASI and CCA-IMT were found to be greater in diabetic patients, while no differences in AIx were observed between the two groups. CCA-IMT was independently correlated to the three measures of arterial stiffness in both groups. We found an increase in CCA-IMT of 0.40, 0.24 and 0.36 mm in diabetics, and of 0.48, 0.17 and 0.55 mm in non-diabetics for each unit increase in AASI, AIx and PWV. The variability of CCA-IMT was explained mainly by AASI, AIx and gender in diabetic patients, and by age, gender, AASI and PWV in non-diabetic patients. CONCLUSIONS: CCA-IMT showed a positive correlation to PWV, AASI and AIx in subjects with and without type 2 diabetes. However, when adjusting for age, gender and heart rate, the association to PWV was lost in diabetic patients, in the same way as the association to Alx in non-diabetic patients. The present study demonstrates that the three measures taken to assess arterial stiffness in clinical practice are not interchangeable, nor do they behave equally in all subjects.

RESUMO

Fundamento y objetivo: Estimar la prevalencia de afectación renal en pacientes hipertensos de nuevo diagnóstico e identificar los factores relacionados con esta afectación renal. Pacientes y métodos: Estudio transversal de 425 hipertensos de reciente diagnóstico en atención primaria. La afectación renal se ha valorado con la creatinina, índice albumina/ creatinina y tasa de filtrado glomerular (TFG). Los factores de riesgo cardiovascular, la lesión orgánica subclínica y la enfermedad cardiovascular se analizaron según los criterios de la Guía Europea de Hipertensión de 2007. Resultados: Edad media de 58,96 (DE: 12,73) años, el 63,3% eran varones. Encontramos dislipidemia en el 80%, obesidad abdominal en el 49% y síndrome metabólico en el 36%. Presentaron creatinina elevada el 3,3%, TFG disminuida el 9,6%, afectación renal oculta el 6,4%, oligoalbuminuria el 7,5% y nefropatía el 2,4%. Los hipertensos con afectación renal (17,88%) tenían mayor edad, presión arterial sistólica más elevada, mayor porcentaje de síndrome metabólico, íntima-media de carótida e índice tobillo/brazo patológico, así como mayor proporción de enfermedad cardiovascular. Las variables asociadas a la afectación renal fueron la presencia de síndrome metabólico (OR=11,12) y el índice tobillo/brazo patológico (OR=17,55). Las variables asociadas a creatinina elevada fueron sexo, índice tobillo/brazo patológico y síndrome metabólico; las variables asociadas a TFG disminuida fueron edad, sexo, índice tobillo/brazo patológico, síndrome metabólico e índice de masa corporal, y la variable asociada al índice albumina/creatinina elevado fue la diabetes mellitus. Conclusión: Se detecta afectación renal aproximadamente en 2 de cada 10 hipertensos cuando, además de la creatinina sérica, realizamos índice albumina/creatinina y TFG. El síndrome metabólico y el índice tobillo/brazo patológico son los principales indicadores de afectación renal (AU)


Background and objective:To estimate renal disease in recently diagnosed hypertensive patients, and to identify factors related to renal disease. Patients and methods: Cross-sectional study, with 425 hypertensive patients recently diagnosed in primary health care; renal disease was estimated with serum creatinine, albumin/creatinine index and glomerular filtration rate (GFR). We analyzed cardiovascular risk factors (CRF), subclinical organ injury and cardiovascular disease following the criteria of the 2007 European Guide of Hypertension. Results: Average age: 58,96±12,73 years old, 63,3% male. We found dyslipemia in 80%, abdominal obesity in 49% and metabolic syndrome in 36% patients. These patients showed increased serum creatinine 3,3%, a reduction in GFR 9,6%, hidden renal disease 6,4%, microalbuminuria 7,5% and nephropathy 2,4%. Hypertensive patients with renal disease (17,88%) were older, with higher systolic pressure, higher incidence of metabolic syndrome, abnormal carotid intima-media thickness and ankle-arm index, and presence of cardiovascular disease. Variables associated with renal disease were metabolic syndrome (odds ratio =11,12) and ankle-arm index (odds ratio =17,55). Variables related to creatinina were sex, ankle-arm index and metabolic syndrome; variables related to GFR were sex, age, ankle-arm index, metabolic syndrome and body mass index (BMI); variables related with albumin/creatinine index included diabetes mellitus. Conclusions: Renal disease is detected in about 2 out of 10 hypertensive patients, when, besides serum creatinina, we analyze albumin/creatinine index and GFR. Metabolic syndrome and ankle-arm index are the main variables associated with renal disease (AU)
