Five-year risk of all-cause death and cardiovascular events in women with gestational diabetes and hypertensive disorders of pregnancy
Full text linkBackground: . The long-term impact of gestational complications on cardiovascular outcomes in women remains a subject of debate. Aim: To assess the 5-year risk of cardiovascular events and all-cause mortality in women with gestational diabetes and hypertension. Methods: Retrospective study utilising an health research network(TriNetX). The primary outcome was the composite risk of a cardiovascular event within 5 years with secondary outcomes being its components (all-cause death, acute heart failure, myocardial infarction, ischaemic stroke). Women were categorised into 8 different groups based on the ICD-codes for pregnancy related complications recorded 9 months before the delivery:1) gestational diabetes,2) gestational hypertension,3) gestational diabetes with gestational hypertension,4) gestational diabetes with gestational hypertension without pre-eclampsia or eclampsia,5) gestational diabetes with pre-eclampsia or eclampsia,6) gestational hypertension without pre-eclampsia or eclampsia,7) pre-eclampsia or eclampsia,and 8) no gestational complications. Cox-regression analyses were used to produce hazard ratios (HRs) and 95 % confidence intervals (CI) before and after propensity score matching (PSM). Results: We identified, 24,402 women with gestational diabetes and gestational hypertension and 920,478 without gestational complications. After PSM, compared to women without pregnancy complications, women with gestational diabetes and gestational hypertension had a higher 5-year risk of composite outcome(HR 2.25,95 %CI 2.02-2.51), all-cause death(HR 1.64,95 %CI 1.31-2.06), acute heart failure(HR 2.06,95 %CI 1.69-2.52), myocardial infarction(HR 2.46,95 %CI 1.93-3.14), and ischemic stroke(HR 2.37,95 %CI 2.06-2.74). Women who experienced pre-eclampsia or eclampsia showed the highest risk of primary and secondary outcomes. Conclusions: Gestational complications are associated with worse long-term cardiovascular outcomes. There is a clear call to action required to improve the longitudinal management of gestational complications to improve women's long-term health
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
Feasibility of Using Appreciative Inquiry to Improve Maternity Services in District Hospitals of Malawi
No full textPurpose
In Malawi as demand for maternity services continues to surpass supply and overstretch frontline healthcare providers, it is important to improve the quality of maternity care to address the burden of maternal mortality and morbidity. Appreciative Inquiry (AI) is a method through which healthcare providers can make organisational change to improve clinical care and their working lives. It harnesses the energy and ideas of staff through a four-stage cycle: Discover (how it is now), Dream (of what it could be), Design (concrete plans) and Destiny (implement plans).
The purpose of the study was to assess the feasibility of implementing Appreciative Inquiry in three district level facilities in Malawi using participatory aproach.
Methods
Between April 2015 and January, 2016 we adapted and implemented AI through participatory action cycle sessions.
Findings:
We have successfully implemented AI with contributions from the entire ward team (patient attendants, nurses, clinical officers and clerks). Each team chose a different focus for their activities including ‘team spirit’ and ‘infection prevention ’. In two hospitals there have been some steps towards change, driven largely by key midwives team leaders. In one hospital the team have lobbied the management to have security guards to support their ‘traffic control’ policies in addition to successfully implementing the removal of shoes before entering the nursery and kangaroo wards. Another team has reduced the number of incidences of overfull sharps bins and waste in the incorrect bins on the ward. The main challenges faced were from constantly changing teams and the lack of time and resources to dedicate to the change process.
Conclusion
It is feasible to implement AI in maternity settings in Malawi when the care providers stay positive. However, the presence of committed champions seems important and health system challenges necessitate realistic goal setting; further study is needed to understand the effectiveness of the interventio
