Triage body temperature predicts outcome in cats at emergency department admission: a retrospective study of 1440 cases (January 2018 to December 2021)
Full text linkOBJECTIVES: The aim of the study was to evaluate the association between triage body temperature (BT) and outcome in cats presenting to the emergency department (ED). METHODS: A retrospective observational study was conducted on cats presented to the ED. BT, clinical diagnosis and outcome were recorded. BT was categorised as follows: normothermia (37.8-39.7°C); hyperthermia (⩾39.8°C); mild hypothermia (36.8-37.7°C); moderate hypothermia (35.6-36.7°C); severe hypothermia (33.1-35.5°C); and critical hypothermia (⩽33°C). Outcome in the ED was categorised as death, euthanasia, hospital admission and discharge. Outcome at hospital discharge was evaluated in patients admitted to the intensive care unit (ICU). Systemic inflammatory response syndrome (SIRS) was identified in patients. No-SIRS cats were divided into three disease categories (urinary system, cardiovascular and miscellanea) and SIRS cats into four categories (urinary system, cardiovascular, trauma and miscellanea). The presence of sepsis was evaluated. Non-parametric statistics were used. RESULTS: A total of 1440 cats were included. The hospital mortality rate was 21.9%. Hypothermia in the ED was reported in 510 (35.4%) cats, normothermia in 849 (59%) cats and hyperthermia in 81 (5.6%) cats. In the ED, the median temperature in non-survivors (35.4°C, 95% confidence interval [CI] 34.6-36.3) was significantly lower than in survivors (38.2°C, 95% CI 38.1-38.3; P <0.0001). The risk of non-survival in the ED was significantly higher in cats with a decreased BT, progressively increasing with the severity of hypothermia (P <0.0001). Furthermore, BT was significantly associated with a higher risk of mortality in the ICU (P <0.0001). A diagnosis of sepsis was associated with a high prevalence of hypothermia (79/124 cats, 63.7%) and a higher risk of non-survival (odds ratio [OR] 2.62, 95% CI 1.52-4.54; P = 0.0006). The mortality risk significantly increased in SIRS cats with a cardiovascular disease (OR 8.27, 95% CI 4.09-16.68; P <0.0001). CONCLUSIONS AND RELEVANCE: Hypothermia is common in cats at ED admission and is significantly associated with outcome. Triage hypothermia might identify patients with sepsis or SIRS complicated by comorbidities, such as cardiovascular and urinary diseases
Classification of Septic Shock Phenotypes Based on the Presence of Hypotension and Hyperlactatemia in Cats
Full text linkBackground: Three different phenotypes of septic shock based on changes in blood pressure and lactate are recognized in people. Dysoxic shock, representing the combination of fluid-refractory hypotension and hyperlactatemia, is characterized by greater disease severity and mortality compared to cryptic shock (hyperlactatemia alone) and vasoplegic shock (hypotension with normal blood lactate). Little is known about septic shock and specifically its phenotypes in cats. Objective: To analyze the characteristics and prognostic implications of three septic shock phenotypes in cats with sepsis. Methods: Cats with septic shock were prospectively included. Septic shock was defined by the presence of hypotension (mean blood pressure <60 mmHg) requiring vasopressor support and/or persistent hyperlactatemia (>4 mmol/L) and classified in three subgroups: dysoxic shock, vasoplegic shock and cryptic shock. Clinical and clinicopathological variables including APPLEfast and APPLEfull scores, occurrence of multi-organ dysfunction syndrome (MODS; presence of at least two dysfunctional organs simultaneously) and outcome were compared among subgroups. Cats with sepsis showing normal blood pressure and lactate concentrations hospitalized during the study period were included as uncomplicated sepsis, and compared to cats with septic shock for selected variables. Length of hospital stay and mortality were evaluated in the whole study population. Odds ratios for mortality were calculated using logistic regression analysis. Significance was set at P < 0.05. Results: The study enrolled 48 cats with uncomplicated sepsis and 37 cats with septic shock (dysoxic shock n = 17; vasoplegic shock n = 11; cryptic shock n = 7). Cats with dysoxic shock had significantly higher APPLEfast and APPLEfull scores compared to vasoplegic and cryptic shock. Mortality rates were not significantly different among cryptic (57%), dysoxic (65%) and vasoplegic shock (91%), while MODS occurrence was significantly lower in cats with cryptic shock (57%) compared to patients affected by dysoxic (94%) and vasoplegic (100%) shock. Cats with septic shock had higher frequency of MODS and greater mortality rate than cats with uncomplicated sepsis. Conclusion: Despite similar in-hospital mortality, cats with dysoxic and vasoplegic shock are characterized by having higher occurrence of multi- organ dysfunction compared to cats affected by cryptic shock. Results from this study suggest novel means of identifying high-risk subgroups of septic cats
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
