Consumption of alcohol and blood pressure: Results of the ELSA-Brasil study

<div><p>Background</p><p>Prevention and reduction of excessive use of alcohol represents damages to society in general. In turn, arterial hypertension is the main attributable risk factor premature life lost years and disability.</p><p>Objective</p><p>To investigate the relationship between alcohol consumption and high blood pressure in participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).</p><p>Methodology</p><p>A baseline data of total of 7,655 participants volunteers between 35 and 74 years of age, of both genders, in six educational and research institutions of three different regions of the country were interviewed between 2008–2010. Socioeconomic, haemodynamic, anthropometric and health data were collected in the research centers of ELSA-Brasil. The presence of high blood pressure was identified when the systolic blood pressure was ≥140 mm Hg and/or the diastolic was ≥90 mm Hg. Alcohol consumption was estimated and categorized regarding consumption and pattern of ingestion. The Student’s t-test, chi-squared and logistic regression tests were used for analysis, including potential co-variables of the model, and a 5% significance level was adopted.</p><p>Results</p><p>A dose-response relation was observed for the consumption of alcohol (g/week) in systolic blood pressure and diastolic blood pressure. Alcohol consumption was associated with high blood pressure in men who reported moderate (<i>OR</i> = 1.69; _95%CI 1.35–2.11) and excessive (<i>OR</i> = 2.70; _95%CI 2.04–3.59) consumption. Women have nearly three times more chance of presenting elevated blood pressure when presenting excessive consumption (<i>OR</i> = 2.86, _95%CI 1.77–4.63), and binge drinkers who drink more than 2 to 3 times a month have approximately 70% more chance of presenting with elevated blood pressure, after adjusting for consumption of drinks with meals.</p><p>Conclusion</p><p>The consumption of alcohol beverages increases the odds of elevated blood pressure, especially among excessive drinkers.

Nuclear cardiology practice and associated radiation doses in Europe: results of the IAEA Nuclear Cardiology Protocols Study (INCAPS) for the 27 European countries

Purpose: Nuclear cardiology is widely used to diagnose coronary artery disease and to guide patient management, but data on current practices, radiation dose-related best practices, and radiation doses are scarce. To address these issues, the IAEA conducted a worldwide study of nuclear cardiology practice. We present the European subanalysis. Methods: In March 2013, the IAEA invited laboratories across the world to document all SPECT and PET studies performed in one week. The data included age, gender, weight, radiopharmaceuticals, injected activities, camera type, positioning, hardware and software. Radiation effective dose was calculated for each patient. A quality score was defined for each laboratory as the number followed of eight predefined best practices with a bearing on radiation exposure (range of quality score 0&nbsp;–&nbsp;8). The participating European countries were assigned to regions (North, East, South, and West). Comparisons were performed between the four European regions and between Europe and the rest-of-the-world (RoW). Results: Data on 2,381 European patients undergoing nuclear cardiology procedures in 102 laboratories in 27 countries were collected. A cardiac SPECT study was performed in 97.9&nbsp;% of the patients, and a PET study in 2.1&nbsp;%. The average effective dose of SPECT was 8.0 ± 3.4&nbsp;mSv (RoW 11.4 ± 4.3&nbsp;mSv; P &lt; 0.001) and of PET was 2.6 ± 1.5&nbsp;mSv (RoW 3.8 ± 2.5&nbsp;mSv; P &lt; 0.001). The mean effective doses of SPECT and PET differed between European regions (P &lt; 0.001 and P = 0.002, respectively). The mean quality score was 6.2 ± 1.2, which was higher than the RoW score (5.0 ± 1.1; P &lt; 0.001). Adherence to best practices did not differ significantly among the European regions (range 6 to 6.4; P = 0.73). Of the best practices, stress-only imaging and weight-adjusted dosing were the least commonly used. Conclusion: In Europe, the mean effective dose from nuclear cardiology is lower and the average quality score is higher than in the RoW. There is regional variation in effective dose in relation to the best practice quality score. A possible reason for the differences between Europe and the RoW could be the safety culture fostered by actions under the Euratom directives and the implementation of diagnostic reference levels. Stress-only imaging and weight-adjusted activity might be targets for optimization of European nuclear cardiology practice

Current worldwide nuclear cardiology practices andradiationexposure: results from the 65 country IAEA nuclear cardiology protocols cross-sectional study (INCAPS)

Aims To characterize patient radiation doses from nuclear myocardial perfusion imaging (MPI) and the use of radiationoptimizing 'best practices' worldwide, and to evaluate the relationship between laboratory use of best practices and patient radiation dose. Methods and results We conducted an observational cross-sectional study of protocols used for all 7911 MPI studies performed in 308 nuclear cardiology laboratories in 65 countries for a single week in March-April 2013. Eight 'best practices' relating to radiation exposurewere identified a priori by an expert committee, and a radiation-related quality index (QI) devised indicating the number of best practices used by a laboratory. Patient radiation effective dose (ED) ranged between 0.8 and 35.6 mSv (median 10.0 mSv). Average laboratory ED ranged from 2.2 to 24.4 mSv (median 10.4 mSv); only 91 (30%) laboratories achieved the median ED ≤ 9 mSv recommended by guidelines. Laboratory QIs ranged from 2 to 8 (median 5). Both ED and QI differed significantly between laboratories, countries, and world regions. The lowest median ED (8.0 mSv), in Europe, coincided with high best-practice adherence (mean laboratory QI 6.2). The highest doses (median 12.1 mSv) and low QI (4.9) occurred in Latin America. In hierarchical regression modelling, patients undergoing MPI at laboratories following more 'best practices' had lower EDs Conclusion Marked worldwide variation exists in radiation safety practices pertaining to MPI, with targeted EDs currently achieved in a minority of laboratories. The significant relationship between best-practice implementation and lower doses indicates numerous opportunities to reduce radiation exposure from MPI globally

Personality traits in chronic daily headache patients with and without psychiatric comorbidity: an observational study in a tertiary care headache center

BACKGROUND: Previous studies suggest that patients with Chronic Daily Headache (CDH) have higher levels of anxiety and depressive disorders than patients with episodic migraine or tension-type headache. However, no study has considered the presence of psychiatric comorbidity in the analysis of personality traits. The aim of this study is to investigate the prevalence of psychiatric comorbidity and specific personality traits in CDH patients, exploring if specific personality traits are associated to headache itself or to the psychiatric comorbidity associated with headache. METHODS: An observational, cross-sectional study. Ninety-four CDH patients with and without medication overuse were included in the study and assessed by clinical psychiatric interview and Mini International Neuropsychiatric Interview (M.I.N.I.) as diagnostic tools. Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Hamilton Depression Rating Scale (HAM-D) were afterwards administered. Patients with and without psychiatric comorbidity were compared. Further analyses were made by splitting the whole group according to the headache diagnosis and the presence or not of medication overuse. RESULTS: Psychiatric comorbidity was detected in 44 patients (46.8%) (group A) and was absent in the remaining 50 patients (53.2%) (group B). Mood and anxiety disorders were the most frequently diagnosed (43.6%). In the overall group, mean scores of MMPI-2 showed a high level in the so-called neurotic triad; in particular the mean score in the Hypochondriasis subscale was in the pathologic area (73.55 ± 13.59), while Depression and Hysteria scores were moderate but not severe (62.53 and 61.61, respectively). In content scales, score in Health Concern was also high (66.73). Group A presented higher scores compared to Group B in the following MMPI-2 subscales: Hypochondriasis (p = .036), Depression (p = .032), Hysteria (p < .0001), Hypomania (p = .030). Group B had a high score only in the Hypochondriasis subscale. No significant differences were found between chronic migraine (CM)-probable CM (pCM) plus probable medication overuse headache (pMOH) and chronic tension-type headache (CTTH)-probable CTTH (pCTTH) plus pMOH patients or between patients with and without drug overuse. CONCLUSIONS: The so-called “Neurotic Profile” reached clinical level only in CDH patients with psychiatric comorbidity while a high concern about their general health status was a common feature in all CDH patients
