Fetomaternal outcome of pregnancies complicated by cardiac disease
Get PDFObjectives: The aim of this study was to assess the Fetomaternal outcome of pregnancies Complicated by Cardiac Disease. Methods: This is an observational study that includes prospective analysis of patients admitted in labour room, at Narayana Hrudayalaya Institute of Medical Sciences with pregnancy complicated by heart disease. Data was collected from 110 women during the time period from November 2013 to September 2015. Results: Out of 3588 cases delivered in the hospital, incidence of pregnancies complicated by heart disease was 3.06%. 43 patients (39%) were in the age group of 21-25 years.In 30% (n = 33) women, the diagnosis of heart disease was made during pregnancy and labour. Principal etiology was Rheumatic in 46% (n = 50), Congenital in 32% (n = 35), MVP in 9% (n = 10), cardiomyopathy in 7% (n =8) and 6% had rheumatic superimposing on congenital heart disease, arrhythmias, dissecting aneurysm of aorta.Septal defects were the most common form of congenital heart disease. 42 patients (38%) underwent surgical and nonsurgical (PTMC) interventions before pregnancy in both congenital and rheumatic group. PTMC in 11, valve repair in 6, and valve replacement in 10 patients. 5 patients underwent PTMC in antenatal period. Patients in NYHA class I & II (n = 89, 80.9%) had fewer maternal complications and their babies had a higher birth weight than those in NYHA class III&IV (n = 21, 19%). 69% (n = 76) had term deliveries, 17% (n = 19) had preterm deliveries, and 12% (n = 14) had abortions. 40.6 % patients had vaginal deliveries, 59.3% had caesarean section. Maternal mortality was 3.63% (n = 4) and maternal cardiac complications occurred in 10%, predominant being CCF. 61 patients had live birth with normal birth weight, 35 patients had low birth weight, 1 patient had intrauterine death and 4 patients had early neonatal death, 3 due to prematurity, 1 due to birth asphyxia due to shoulder dystocia. Conclusion: Pregnancy in women with heart disease is associated with significant cardiac and neonatal complications,despite state-of-the-art obstetric and cardiac care. Multidisciplinary approach should be adopted in the management of cardiac patient to minimize maternal and neonatal complications. Rheumatic heart disease was the predominant type. Patients in NYHA class I and II had abetter maternal and fetal outcome than those in NYHA class III and IV. Surgical correction of the cardiac lesion prior topregnancy was associated with better pregnancy outcome. Pregnant women with prosthetic valves tolerated pregnancy well
Effect of follicular size on the day of trigger on OOCYTE and EMBRYO quality in clomiphene citrate protocol- A comparitive retrospective study
Get PDFObjective: To compare the effect of follicular size on the day of trigger on the oocyte and embryo quality in clomiphene citrate protocol in patients undergoing IVF/ICSI. Materials and Methods: A Retrospective comparative analysis was done in patients who underwent IVF/ICSI with clomiphene citrate protocol between 2016-2018 in craft hospital and research centre kodungallur Kerala. 242 patients who met the inclusion criteria of primary/secondary infertility, <40yrs old, normal male factor. Excluding > 4oys old, endometriosis, PCOS, male factor infertility. Group A: included 83 patients with lead follicle measuring 21-23 mm on the day of trigger. Group B: Included 159 patients with lead follicle measuring 17-19mm on the day of trigger. Inj ovitrille 250 mcg was given as a trigger. Oocytes retrieved after 36hrs by transvaginal approach. Both groups were compared for number of oocytes retrieved, number of mature oocytes, number of Day 3 good embryos. Statistical analysis was done by independent sample T-test for all variables. Results: No statistical difference between age and AFC in both groups. Statistical difference in number of oocytes retrieved (p value -0.055). No statistical difference in number of mature oocytes and number of day 3 embryos. Conclusion: Women who underwent IVF/ICSI with clomiphene citrate protocol with a lead > 20mm had less number of oocytes retrieved when compared to <20mm lead follicle on the trigger day and had similar number of mature oocyte and day 3 embryos. No beneficial effect by waiting for the lead follicle to reach beyond 20mm in size
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
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
