Electronic Medical Record-Assisted Telephone Follow-Up of Breast Cancer Survivors During the COVID-19 Pandemic: A Single Institution Experience
Full text linkPURPOSE: The COVID-19 outbreak rapidly became a public health emergency and led to radical changes in patient management. From the start of the pandemic, we used electronic medical record-assisted telephone follow-up (E-TFU) of cancer survivors (CS) to minimize hospital exposure. The aim of this prospective study was to assess how breast cancer survivors (bCSs) perceived E-TFU.MATERIALS AND METHODS: A 15-item survey was e-mailed to bCSs who had been managed with E-TFU. The responses were measured using Likert-like scales and were correlated with the main characteristics of the bCS using Pearson's test.RESULTS: One hundred thirty-seven of 343 bCSs (40%) completed the survey between March 9 and June 2, 2020. Their median age was 59 years. Although 80.3% of bCSs were satisfied with E-TFU, only 43.8% would like to have E-TFU in the future. A low educational level was correlated with higher COVID-19-related anxiety (P = .025). An older age (P = .002) and a low educational level (P < .0001) were correlated with the need to be accompanied to reach the hospital. A personal history of second cancer was inversely correlated with understanding medical advice (P = .015) and the expectation of feeling relief after a follow-up visit (P = .0027). Furthermore, pandemic phase II was correlated with satisfaction with E-TFU (P = .010).CONCLUSION: E-TFU was an important means of avoiding hospital contacts during the COVID-19 pandemic, and the majority of bCSs in the survey were satisfied with this procedure. Further studies are needed to investigate the implementation of telemedicine even outside an emergency situation
Sequencing new agents after docetaxel in patients with metastatic castration-resistant prostate cancer
No full textTwo new hormonal agents (NHAs), abiraterone and enzalutamide, and one chemotherapeutic agent, cabazitaxel (CABA) improved overall survival (OS) in patients with metastatic castration-resistant prostate cancer (mCRPC) who progress after docetaxel. Although several analyses of patient cohorts receiving a sequence of two different new agents (NAs) after docetaxel have been published, no definite conclusions can be drawn regarding the best treatment strategy
Pretreatment lung immune prognostic index as biomarker in advanced non-small-cell lung cancer patients receiving first line pembrolizumab
No full textBackground: To investigate the role of pretreatment lung immune prognostic index (LIPI) as biomarker in PD-L1 ≥50% non-small-cell lung cancer patients receiving pembrolizumab. Patients & methods: We retrospectively identified 117 patients, divided into 3 prognostic groups according to LIPI score. For each patient, we evaluated 1-year overall survival (OS) and progression-free survival rate. C-statistic and survival receiver operating characteristic curves were used to study discrimination of LIPI. Results: After a median follow-up of 11.7 months, 1-year OS rate was 60.1%, 35.3% and 28.6%, while 1-year progression-free survival rate was 39.1%, 20.6% and 14.3% in good, intermediate and poor LIPI groups, respectively (p < 0.001). The c-statistic and area under the curve of LIPI were 0.63 and 0.662 for OS and 1-year OS, respectively. Conclusions: Higher LIPI score is related to worse survival in advanced non-small-cell lung cancer patients treated with first-line pembrolizumab. However, based on c-statistic and area under the curve, LIPI does not represent a good prognostic survival model
Serial 18F-choline-PET imaging in patients receiving enzalutamide for metastatic castration-resistant prostate cancer: response assessment and imaging biomarkers
No full textHigh rate of non-target lesions in metastatic castration-resistant prostate cancer usually limits applicability of Response Evaluation Criteria in Solid Tumors (RECIST) criteria, and this has led to a growing interest in using PET/computed tomography (CT). We prospectively investigated the role of (18)F-choline (FCH)-PET/CT in patients receiving enzalutamide after docetaxel
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
