Splenic involvement of tuberculosis: US and CT findings
No full textTuberculosis (TB) of spleen is rare and usually occurs in miliarv form. Macronodular form is extremely rare, Immunodeficiency associated with alcoholism IV drug abuse, diabetes, cancer, corticosteroid therapy, and AIDS are prominent risk factors. Early diagnosis and treatment are important, because untreated abdominal TB carries a 50% mortality rate. We report US and CT of five cases with splenic TB. Our cases showed multiple small hypoechoic and hypodense nodules on US and CT, respectively, except one case whose US was normal. All cases also had extrasplenic involvement. The diagnosis of TB was established in two cases by cervical and in one case by submandibular lymph node biopsy, in one case by peritoneal biopsy, and in one case by a typical spinal lesion at L2-3. The US and CT findings are not specific for TB, but especially in endemic regions TB should be included in the differential diagnosis of Splenic lesions. © 1994 Springer-Verlag
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
Intensive Insulin Titration with Insulin Glargine in Insulin-Naive Type 2 Diabetic Patients in Turkey: LANTIT Study
Get PDFWOS: 000362601700003Purpose: This open-label, single-arm, phase 4 study was designed to evaluate the efficacy of intensive insulin glargine titration in type 2 diabetes mellitus (T2DM) patients for 6 months to reach good glycaemic control. Material and Method: Two hundred-forty one insulin-naive T2DM patients were included. The primary efficacy variable was the glycaemic control (HbA1c level of <= 7%). The secondary variables were a fasting blood glucose (FBG) level of <100 mg/dL, the final dose of basal insulin, number of dose adjustments, time to dose titration in reaching target HbA1c level of <= 7%, weight gain and treatment satisfaction using the Diabetes Treatment Satisfaction Questionnaire (DTSQ). Hypoglycemia, severe hypoglycemia and adverse events were also assessed. Results: The mean (+/-SD) HbA1c level of 8.8+/-0.6% at baseline decreased to 7.4+/-0.9% on day-90 (p<0.001) and to 7.3+/-0.9% on day-180 (p<0.001). The percentage of patients with HbA1c <=%7 was 36.9% on day-90 and 40% on day-180. The mean FBG of 186.3+/-52.5 mg/dL at baseline decreased to 111.5+/-36.6 mg/dL on day-90 (p<0.001) and to 114.1+/-34.8 mg/dL on day-180 (p<0.001). The mean insulin glargine dose on the last day of FBG measurement (day-89) was 32.7+/-15.5 IU and the mean number of titrations was 12.7+/-6.6. These values on day-179 were 36.8+/-19.4 IU and 5.8+/-5.7, respectively. The total DTSQ score (20.3+/-7.7) and scores for each item at baseline showed improvement on day-180 (p<0.001). The most frequently reported adverse reactions were hypoglycaemia (49.7%) and weight gain (9.5%). Serious hypoglycaemia cases reported during the first and the second 3-month periods were 11.2% and 13.3%, respectively. Discussion: In conclusion, the use of insulin glargine with intensive dose titration is effective and safe in T2DM patients.Amaç: Bu açık-etiketli, tek-kollu faz 4 çalışma, insulin glarjin ile tedavi edilen tip 2 diabetus mellitus (T2DM) hastalarında iyi glisemik kontrol için etkili dozlara ulaşmada yoğunlaştırılmış insülin titrasyonunu değerlendirmek amacıyla tasarlanmıştır. Gereç ve Yöntem: Önceden insülin kullanmamış 241 T2DM hastası çalışmaya alınmıştır. Birincil değerlendirme kriteri glisemik kontrol (HbA1c seviyesi ?%7), ikincil kriterler ise açlık kan şekeri (AKŞ) <100 mg/dL, son bazal insülin dozu, doz ayarlama sayısı, hedef HbA1c seviyesine ulaşıldığı an doz titrasyonuna kadar geçen zaman, kilo alımı ve tedavi memnuniyetinin Diyabet Tedavi Memnuniyet Anketi (DTSQ) ile değerlendirilmesi olmuş, ayrıca hipoglisemi, ciddi hipoglisemi ve advers olaylar da değerlendirilmiştir. Bulgular: Başlangıçtaki ortalama ± SD HbA1c seviyesi %8,8±0,6, 90. günde %7,4±0,9 seviyesine (p<0,001), 180. günde ise %7,3±0,9 seviyesine (p<0,001) düşmüştür. HbA1c seviyesi ?%7 olan hastaların oranı 90. günde %36,9 iken 180. günde %40 olmuştur. Ortalama AKŞ başlangıçta 186,3±52,5 mg/dL iken 90. günde 111,5±36,6 mg/dL’ye (p<0,001), 180. günde ise 114,1± 34,8 mg/dL’ye düşmüştür (p<0,001). Son AKŞ ölçümü sırasında (89. gün) ortalama insülin glarjin dozu 32,7±15,5 IU ve ortalama titrasyon sayısı ise 12,7±6,6 idi. Bu değerler 169. gün 36,8±19,4 IU ve 5,8±5,7 idi. Total DTSQ skoru (20,3±7,7) ve her bir madde için 180. günde başlangıç vizitine göre bir iyileşme izlendi (p<0,001). En sık bildirilen advers olay hipoglisemi (%49,7) ve kilo alımı (%9,5) idi. İlk ve ikinci 3 aylık dönemlerde bildirilen ciddi hipoglisemi olayları sırasıyla %11,2 ve %13,3 idi. Tartışma: Sonuç olarak yoğunlaştırılmış doz titrasyonu ile insülin glarjin kullanımı T2DM hastalarında etkili ve güvenli bir tedavi seçeneğidir
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
Solitary nodules distrubution in the thyrold
Get PDFSoliter tiroid nodülleri kanser riski taşımayan nedeniyle önemlidir. Bu çalışma 1499 soliter tiroid nodüllü olgu üzerinde yapılmıştır. Hipoaktif nodüller tüm tiroid bölgelerinde normoaktif ve hiperaktif nodüllerden istatistiki açıdan anlamlı derecede yüksek bulundu. Kadınlarda sağ lobda, sol lob ve istmusa göre daha fazla nodül görülürken, erkeklerde belirgin bir farklılık saptanmadı.The solitary nodules of thyroid are important, because they are confused with thyroid carcinomas. We studied 1499 solitary thyroid nodules. Hypoactive nodules are significantly higher than normoactive and hyperactive nodules in all the regions of the thyroid. There is not any differentiation in the number of the same kind of the nodules in the men while right lobs have more nodules than left lobes and isthmus, in the women
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
