Factors predicting hyperimmune response in COVID-19 patients presenting to the emergency department
Aim: The aim of this study is to determine the predictive parameters that can be used in the early determination of hyperimmune response syndrome in the Emergency Department. Material and Methods: This is a cross-sectional, retrospective study. Patients over the age of 18 who were admitted to the emergency department with a pre-diagnosis of COVID-19, and who were admitted to the intensive care unit were included in the study. Demographic data and laboratory findings were obtained from the hospital information system and patient files. Patients' thoracic computerized tomography images were classified into two groups. The classic involvement includes bilateral basal ground-glass opacities, crazy paving, reverse halo, per lobular pattern, and peripheral consolidation. All other images were included as non-classic COVID-19 involvement. Results: A total of 202 patients were included. Hyperimmune response development was detected in 74 (36.6%) patients. When laboratory values were examined, ferritin and ALT values were found to be higher, WBC and lymphocyte values were found to be lower in patients who developed a hyperimmune response (p<0.01, p<0.01, p=0.038 and p=0.004, respectively). In the logistic regression analysis of the values that can be effective in the development of the hyperimmune response, classic imaging had a statistically significant effect (Odds ratio 0.449 [95% confidence interval, CI = 0.244-0.827], non-classic vs classic[reference]). No statistically significant effect was found in the analysis of other values. Discussion: Classical chest tomography findings can be useful as a preliminary parameter in the development of hyperimmune response
Pseudoulnar Palsy Due to Ischemic Stroke; Case Report
Isolated motor nerve paresis can occur due to central nervous system lesions. This condition is extremely rare, they are often misdiagnosed as a peripheral nerve lesion. 83-year-old male, applied to our hospital with 4th and 5th digit weakness. Neuroimaging revealed cortical-subcortical diffusion restriction in the medial gyrus of the precentral gyrus. The patient was diagnosed as ischemic stroke. In this article, we presented a case of ischemic stroke that mimics ulnar nerve paresis and be easily overlooked

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
The role of neutrophil-albumin ratio in the diagnosis of acute appendicitis and its efficacy in predicting perforation
BACKGROUND: Acute appendicitis (AA) is one of the most common causes of abdominal pain in patients presenting to the emergency department with abdominal pain, and despite developments in radiological imaging for its diagnosis, researchers are still in pursuit of a simpler, cheaper, and safer biomarker. Our study investigated the usability of the neutrophil-albumin ratio, a biomarker that predicts prognosis in cases with severe inflammation, in diagnosing AA and anticipating perforation. METHODS: Our study is a retrospective and cross-sectional study. The study was conducted with patients who presented to the emergency department between January 2018 and December 2020 and were hospitalized with a preliminary diagnosis of AA. The cases were first divided into two groups as Not appendicitis and AA, and then the patients with AA were divided into two subgroups as Perforated and Non-perforated. The demographic data of the patients, their symptoms, physical examination findings, and the decision-making process for surgery were noted. The neutrophil count and albumin levels detected in the blood samples obtained at the time of admission to the emergency department were noted. Afterward, the neutrophil-albumin ratio (NAR) was calculated and the cutoff level was determined to predict the diagnosis of AA and the development of perforation. RESULTS: The rate of complaints of pain in the periumbilical region was significantly higher in the patient group without AA compared to the patients in the AA group (70.6% and 40.3%, p=0.034). Although the leukocyte count, neutrophil count and percentage, and NAR were significantly higher in the AA group, the lymphocyte count was found to be significantly lower (p=0.005). However, no significant correlation was found between the NAR and the development of perforation (p=0.697). CONCLUSION: The NAR is useful for the diagnosis of AA. Nevertheless, it is not a sufficient biomarker for detecting perforation
Akut aort diseksiyonu tanısında kullanılabilecek kan parametreleri
Amaç: Akut aort diseksiyonu yüksek mortalite ve morbiditeye sahip bir hastalıktır. Oldukça geniş semptomlara neden olması sebebiyle tanısı sıklıkla atlanmakta veya akut koroner sendom, gastrointestinal hastalıkları veya serebrovasküler hastalıklarla karıştırılabilmektedir. Çalışmamızda, aort diseksiyonu tanısı alan hastalarda bakılan kan parametrelerinin tanıyı belirlemedeki etkinliğini saptamayı hedefledik. Yöntemler: Çalışmamız retrospektif, kesitsel bir çalışma olarak planlandı. Çalışmamıza üçüncü basamak bir acil servise göğüs ağrısı şikâyeti ile başvuran ve aort diseksiyonundan şüphe edilip, bilgisayarlı toraks ve abdomen anjiografisi (BTAA) çekilen hastalar dâhil edildi. Çalışmaya alınan hastalar iki gruba ayrıldı ve BTAA raporunda aort diseksiyonu saptanıp saptanmamasına göre aort diseksiyonu olanlar “hasta grubu” ve aort diseksiyonu saptanmayanlar ise “kontrol grubu” olarak belirlendi. Hastalara ait yaş, cinsiyet gibi demografik verilerle birlikte, tam kan parametreleri (lökosit, lenfosit, nötrofil, platelet sayıları), C-reaktif protein (CRP), kreatinin değerleri kaydedildi. Bulgular: Çalışmaya 64 hasta dâhil edildi. Çalışmaya alınan hastaların yaş ortalaması 61,48±14,49 olarak saptandı. Hastalar ve kontrol grubu karşılaştırıldığında, aort diseksiyonu olan grubun yaş ortalaması 56,96±10,37, kontrol grubun ise 64,20±15,98 olarak saptandı. Aort diseksiyonu olan grubun yaş ortalaması kontrol grubuna göre istatistiksel olarak anlamlı bir şekilde daha düşüktü (p=0,032). Aort diseksiyonu olan grubun platelet sayısı 199 109/L [162-260], kontrol grubunun ise 260 109/L [348-223] olarak saptandı (p=0,003). Platelet değeri için yapılan ROC analizinde, değer 199 109/L olarak alındığında, aort diseksiyonu için duyarlılık %50,0 (pozitif prediktif değeri =2,5), özgüllük %80,0 (negatif prediktif değeri =0,63) olarak belirlendi (AUC= 0,725 [0,597-0,853], p=0,003). Sonuç: Platelet sayısı ve yaş, aort diseksiyonu tanısında bağımsız risk faktörleridir. Düşük platelet sayısı seviyeleri aort diseksiyonu tanısını destekler
Do we feel safe and confident about workplace violence in the emergency departments?
Study objective: This study aimed to determine the relationship of safety and safety perception of physicians working in emergency departments with socio-demographic characteristics and working conditions. Method: The study included physicians who work in the emergency department. An online questionnaire with two sections was used to collect data. The first section comprised 11 questions about the socio-demographic characteristics and working conditions. The second section comprised the Safety and Confidence Scale for Health Professionals (SCSHP) that assessed how safe physicians felt and how confident they were in the face of violence. Results: A total of 402 participants were included in the study. The median score of the participants with less than one year of work experience was significantly lower than the other subgroups (p 0.05). When the relationship between the working title and SCSHP score was examined, significant differences were found between faculty members and specialist doctors vs general practitioners (p = 0.005, 0.001, respectively), whereas no significant difference was found in SCSHP scores among other subgroups (p > 0.0125). Conclusion: Among physicians working in the emergency department, those with less work experience, female physicians, and those who are unmarried feel less safe and confident about workplace violence.(c) 2022 Elsevier Inc.
