Full text linkGender-dependent impact of COVID-19 lockdown on metabolic and psychological aspects
Full text linkThe first COVID-19 lockdown resulted in enforced quarantine of heavily affected areas with social isolation and related measures by several governments to slow the spread of the disease. The general population experienced several mental and lifestyle changes. Herein, we aimed to evaluate the metabolic and psychological effects induced by lifestyle changes during COVID-19 self-isolation among an Apulian overweight/obese cohort with metabolic disturbances. The study assessed anthropometric data (weight, abdominal circumferences), dietary habits (adherence to the Mediterranean diet, junk food score), lifestyle habits (i.e., smoking, and physical activity), levels of stress and anxiety, and depression. Subjects underwent bioumoral exams before and after self-isolation to monitor glycemic and lipid profiles. A total of 245 subjects (M:F = 118:127) have been included in the study. After lockdown, the number of obese subjects significantly increased in both sexes, and was higher in females than in males (P < 0.0001). Glycemic and lipid profiles worsened, with higher levels of insulinemia, lower levels of HDL cholesterol, and higher levels of triglycerides in females than in males. Adherence to the Mediterranean diet and consumption of junk foods were altered in both groups, especially in females. Psychological aspects were significantly higher in females than in males. Finally, work activities and familial status strongly affected the metabolic and psychological profile. In conclusion, COVID-19 self-isolation induced changes in lifestyle and dietary habits with psychological distress and detrimental effects on metabolic patterns, which were more pronounced in female gender
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
Atherogenic dyslipidaemia and residual cardiovascular risk: Understanding the link to heart disease
No full textBackground: A significant proportion of patients continue to experience cardiovascular (CV) events despite achieving recommended low-density lipoprotein cholesterol (LDL-C) targets, a phenomenon referred to as residual CV risk. Methods: Clinical evidence from large outcome trials highlights the impact of residual risk on cardiovascular disease (CVD) burden, underscoring the need for therapeutic strategies beyond LDL-C lowering. Residual CV risk arises from diverse mechanisms, including persistent atherogenic dyslipidaemia [elevated triglyceride-rich lipoproteins (TRL), high triglycerides (TG), low high-density lipoprotein cholesterol (HDL-C) levels and increased apolipoprotein B (ApoB), Lipoprotein(a) (Lp[a]) and non-HDL-C], chronic inflammation, metabolic disorders and a prothrombotic state. These abnormalities continue to drive atherosclerotic progression in optimally treated patients, underscoring that managing residual CV risk requires a multifaceted approach. Results: Lifestyle and dietary interventions remain foundational, targeting weight reduction, smoking cessation or adoption of a Mediterranean diet. Pharmacological options include statins (as first-line therapy), or the use of ezetimibe, or bempedoic acid since they both have complementary effects to LDL-C lowering. Emerging therapies, including proprotein convertase subtilisin/kexin type 9 (PCSK9), apolipoprotein C-III (ApoC3) and angiopoietin-like 3 (ANGPTL3) inhibitors, demonstrate potential efficacy in favourably modulating lipid profiles and targeting specific components of atherogenic dyslipidaemia (AD). Combination therapies tailored to individual lipid profiles show promise to reduce residual CV risk. Conclusion: The following review aims to provide a comprehensive overview of the latest evidence on the factors driving residual CV risk and the therapeutic interventions available to treat atherogenic dyslipidaemia beyond LDL-C reduction
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
