Özet: Kist hidatik (KH), etiyolojik ajanı olan Echinococcus granulosus olan zoonotik paraziter bir hastalıktır. Türkiye bu hastalığın endemik olduğu ülkeler arasında yer almaktadır. Bu çalışmamızda Türkiye'de önemli bir halk sağlığı sorunu olan KH konusunda yayınlanan araştırma makalelerinin değerlendirilmesi amaçlandı. Çalışmada Scopus bibliyometrik veritabanı bibliyometrik veri analiz tekniği ile incelendi. Makalere ulaşmak için "hidatik" "kist" ve "Türkiye" "İnsan" "Makale" "Echinococcosis" anahtar kelimeleri kullanıldı. Analizde; KH konulu tüm literatürün %95,7'inin Türkiye kaynaklı olduğu saptandı. En fazla yayına sahip kurumlar ise Atatürk Üniversitesi (%9,2) ve İstanbul Üniversitesi (%9,1) oldu. İlk yayın 1966 yılında, en fazla yayın 2007 yılında (n=107) yapılmıştı. Bu makalelerden 56 tanesi en az 56 kez atıf almıştı. Ülkemiz için endemik olan hastalıkla ilgili yayın sayısının son yıllarda azaldığı tespit edilmiştir. Halen vaka sayımız artan bu hastalık hakkında; özellikle önleme ve epidemiyoloji gibi alanlarda bilimsel verimliliğin artırılması gerekmektedir.

Background SARS-CoV-2 infects cells via angiotensin-converting enzyme 2 (ACE2). ACE2 levels are high in the thyroid gland. Although the thyroid gland can be directly infected in COVID-19 patients, the hypothalamic-pituitary-thyroid axis is also affected. Therefore, changes in thyroid function occur in COVID-19 patients. This study aimed to examine the effect of thyroid function tests on the prognosis of COVID-19. Methodology A total of 146 patients who were diagnosed with COVID-19 and treated in the intensive care unit between August and November 2021 and who had no previous history of thyroid disease were included in the study. Demographic information, laboratory tests, and thyroid hormone levels during hospitalization and discharge patterns were evaluated. The patients were divided into two groups: group I included those who were discharged after recovery, and group II included those who did not respond to treatment and died. Results When the fT3 and fT4 levels of the patients were compared, the hormone levels decreased as the clinical severity of the disease increased. The amount of decrease in hormone levels was mostly seen in group II. In the recovered patient group, the amount of hormone decreased was less. The difference between fT3 and ft4 values between the groups was found to be statistically significant ( P = 0.015 and P = 0.004). In addition, the difference between the groups' C-reactive protein (CRP), D-dimer, and ferritin values was statistically significant ( P = 0.036, P = 0.022, and P < 0.000, respectively). There was no statistically significant difference between the groups in terms of demographic characteristics ( P > 0.05). Conclusions Thyroid hormone changes were found to be an important prognostic parameter affecting disease severity and mortality in COVID-19 patients and can be used to predict mortality.

Objectives: Recent publications on coronavirus disease 2019 (COVID-19) suggest that pulmonary embolism (PE) plays an important role in mortality and morbidity. In this context, it is natural that studies on COVID-19-associated PE are increasing rapidly. This study aimed to evaluate the studies on PE associated with COVID-19, see the overall picture in accordance with scientific literature and guide future research. Materials and methods: In this scientometric study, the Web of Science Core Collection (WoSCC) was searched for all documents regarding COVID-19-associated PE. An Excel spreadsheet was applied to analyze the data, and the VOSviewer was used for visualization. Results: A total of 159 records were retrieved in WoSCC. 41.5% (66) of the publications on the subject were original research articles. There were 151 articles in English, five in Spanish, two in German and one in Norwegian. A total of 66 articles were extracted by filtering the results. The mean citation number of these 66 articles was 2.17. Most of the articles were published in the United States of America (USA) (36, 22.64%), Italy (26, 16.35%), and France (20, 12.58%). Although most of the publications were from the USA, it was determined that the majority of citations were to articles published in France and Italy. It was determined that publications made in the journals Radiology, Circulation and European Heart Journal received the most citations when considering the distribution of articles with 10 or more citations. Content analysis showed that the majority of the publications were about the clinical features of the disease (71.2%), while the publications on other issues were limited. Conclusion: Publications from countries other than the USA on COVID-19-associated PE are needed, especially on subjects other than clinical features.
