Impact of Corticosteroid Administration on Fetal Doppler Metrics and Neonatal Outcomes: A Comprehensive Review
No full textAntenatal corticosteroid therapy is a crucial intervention to improve neonatal outcomes in pregnancies at risk of preterm birth. Corticosteroids such as betamethasone and dexamethasone enhance fetal lung maturation and reduce morbidity and mortality. To assess the effects of these drugs, we conducted a systematic review adhering to PRISMA guidelines. Data were located through extensive searches of PubMed, MEDLINE, Cochrane Library, Scopus, and Web of Science, using keywords such as “antenatal corticosteroids,” “fetal Doppler,” and “neonatal outcomes,” and applying filters for human studies published between 2013 and 2024. Studies were selected based on inclusion criteria that prioritized original research articles, systematic reviews, and meta-analyses in English. Screening and eligibility assessments were performed by independent reviewers, with full-text articles. Data extraction involved recording study designs, sample sizes, corticosteroid regimens, Doppler metrics assessed, and neonatal outcomes observed. The extracted data were synthesized qualitatively through narrative methods and quantitatively using meta-analysis where applicable. The review found that corticosteroid administration leads to transient reductions in the resistance and pulsatility indices of key fetal vessels, reflecting improved placental and cerebral perfusion. These Doppler changes correlate with better neonatal outcomes, including reduced respiratory distress syndrome and enhanced neurodevelopmental results. Despite these promising findings, limitations such as small sample sizes and short follow-up periods were noted. Future research should focus on larger, multicenter trials and long-term outcome assessments. Clinicians are advised to incorporate serial Doppler monitoring in high-risk pregnancies to optimize maternal-fetal management and neonatal outcomes
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Psychological Dimensions of Polycystic Ovarian Disorder: A Comprehensive Review of Anxiety and Depression
No full textPolycystic Ovarian Disorder (PCOD) is a common endocrine disorder that significantly impacts both physical and mental health. Women with PCOD have a higher risk of developing anxiety and depression due to hormonal imbalances, body image issues, and psychosocial stressors. Elevated androgen levels and insulin resistance are implicated in mood disturbances, while physical symptoms like hirsutism, acne, and obesity negatively affect self-esteem and contribute to psychological distress. Studies indicate that up to 40% of PCOD patients experience anxiety and approximately 30% suffer from depression. Effective diagnosis and assessment of these mental health issues necessitate standardized screening tools, such as the Beck Depression Inventory (BDI) and General Anxiety Disorder-7 (GAD-7), and comprehensive clinical interviews. Multifaceted treatment strategies are essential, incorporating pharmacological options like SSRIs and hormonal treatments, psychological interventions such as cognitive-behavioural therapy (CBT) and mindfulness-based stress reduction (MBSR), and lifestyle modifications including regular exercise and dietary changes. Supportive care through counselling and community support groups also plays a critical role in enhancing treatment outcomes. Despite these advancements, challenges persist, including underdiagnosis and the lack of standardized diagnostic criteria for mental health disorders in PCOD patients. Future research should focus on interdisciplinary care models, the development of tailored screening tools, and innovative treatments like digital mental health interventions and personalized medicine. In conclusion, addressing the psychological aspects of PCOD through comprehensive, patient-centered care is vital for improving overall quality of life. A holistic approach integrating pharmacological, psychological, and lifestyle interventions, supported by continuous care and community resources, can effectively manage anxiety and depression in women with PCOD, leading to better mental health outcomes and enhanced quality of life
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
