© 2025 The Author(s). Clinical Cardiology published by Wiley Periodicals LLC.Background: Acute myocardial infarction (AMI) remains a leading cause of mortality in the USA, particularly among individuals aged 65 and older. There is limited research about the association between psychoactive substance use and cardiovascular death due to AMI. This study aims to analyze trends in AMI-related mortality among older adults (aged ≥ 65) associated with psychoactive substance use in the USA from 1999 to 2020, with a focus on demographic and geographic variations.
Methods: We conducted a descriptive analysis using death certificates from the CDC's WONDER database. Data were extracted for age, sex, race/ethnicity, urban-rural status, and geographic region. Crude mortality rates and AAMR were calculated, and temporal trends were assessed using Joinpoint regression.
Results: Between 1999 and 2020, there were 231 359 AMI-related deaths among older adults with substance use disorders. Men (39.2) had a markedly higher mortality rate than women (15.0). Mortality rates increased across all age groups, with the most pronounced rise in those aged 85 and older (33.9). Metropolitan areas (22.3) experienced lower mortality rates than nonmetropolitan areas (37.9). The Midwest (32.3) consistently recorded the highest mortality rates, followed by the Northeast (25.0), South (24.5), and West (18.7).
Conclusion: The study reveals notable temporal trends in AMI mortality among older adults with psychoactive substance use, highlighting significant demographic and regional disparities. These findings underscore the need for targeted interventions to address this growing public health issue

© 2025 The Author(s). Endocrinology, Diabetes & Metabolism published by John Wiley & Sons Ltd.Background: Hypertension remains a major contributor to global cardiovascular morbidity and mortality. Aldosterone, a key hormone in blood pressure regulation, plays a significant role in hypertension pathophysiology. This has led to growing interest in aldosterone synthase inhibitors (ASIs) as a potential treatment. This meta-analysis aims to evaluate the efficacy and safety of ASIs in managing hypertension.
Methods: A systematic search of PubMed, Google Scholar and Cochrane Central was conducted up to 13 July 2025, to identify randomised controlled trials (RCTs) evaluating ASIs in hypertensive adults. Data were analysed using RevMan version 5.4, employing random-effects models with significance set at p < 0.05.
Results: A total of 8 RCTs were included, with a total of 2003 participants in the ASI group and 650 participants in the placebo group. ASIs significantly reduced systolic blood pressure (SBP) compared to placebo (MD: -6.01 mmHg; 95% confidence interval [CI]: -9.31 to -2.71; I2 = 85%; p = 0.0004); diastolic blood pressure (DBP) was found to be comparable between the two groups (MD: -2.20 mmHg; 95% CI: -4.46 to 0.06; I2 = 69%; p = 0.06). There was a significant reduction in serum aldosterone levels favouring ASI use (MD: -1.46; 95% CI: -2.76 to -0.16; I2 = 99%; p < 0.00001). The risk of serious (RD: 0.00; 95% CI: -0.01 to 0.02; I2 = 30%; p = 0.75) and non-serious adverse events (RD: 0.05; 95% CI: -0.02 to 0.12; I2 = 64%; p = 0.20) did not differ significantly between ASI and placebo groups. However, ASI use was associated with a significantly higher risk of hyperkalemia (RD: 0.04; 95% CI: 0.02 to 0.06; I2 = 70%; p = 0.002).
Conclusion: ASIs effectively lower SBP and serum aldosterone in adults with hypertension. They appear safe overall but may increase the risk of hyperkalemia
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
