    Classification of the mountain frogs of the Bercelan Plateau (Hakkari), east Anatolia (Turkey)
    Afsar, M; Afsar, B; Arikan, H
    In the present study, the mountain frog population of the Bercelan Plateau (Karadag, Hakkari) in east Anatolia was examined both in terms of their morphology (morphometric and color-pattern characteristics) and serology (blood plasma protein electrophoresis). According to these studies and when compared with frogs from the type localities of Rana macrocnemis BOULENGER, 1885, and Rana holtzi WERNER, 1898, the mountain frogs of the Bercelan Plateau strongly resembled the specimens from Uludag (Bursa) which are currently assigned to R. macrocnemis.

    Rana macrocnemis BOULENGER, 1885, from the Emir Mountains in western inner Anatolia (Turkey)
    Afsar, M; Afsar, B; Arikan, H
    In the present study, mountain frogs from the Emir Mountains (Province of Afyonkarahisar) in western inner Anatolia (Turkey) were examined both morphologically i.e., morphometry and color-pattern, and serologically by analyzing the blood-plasma proteins using polyacrylamide gel disc electrophoresis. Based on the analyses, the mountain frog population of the Emir Mountains represents Rana macrocnemis BOULENGER, 1885.

    Analysis of morphological variations of three Adlerius (Diptera: Psychodidae) species collected in two cutaneous leishmaniasis endemic foci of Turkey
    Kavur, H; Arikan, H; Toz, S; Balcioglu, IC; Ozbel, Y
    Leishmaniasis, transmitted to human by sand flies, is a neglected vector-borne diseases and has two clinical forms: cutaneous (CL) and visceral leishmaniasis (VL) in Turkey. Subgenus of Adlerius are known as probable vectors of both forms of leishmaniasis in Turkey. Examined three species belonging to Adlerius are difficult to distinguish morphologically and have similar taxonomic characters. The aim of this study was to analyse and identify the possible morphological variations, of wild-caught sand fly specimens belonging to Adlerius subgenus. Six and seven morphological characters for female and male specimens were used, respectively. ANOVA, principal component analysis (PCA) and discriminant function analysis (DFA) test were performed to determine the significant morphometric variables of the three species. Univariate and multivariate analyses of 13 morphometric variables via ANOVA, DFA and PCA showed that eight (six for females, two for males) morphometric variables had an accuracy of 100% for discriminating three Adlerius subgenus specimens. The analyses revealed significant differences on several morphological structures of Adlerius specimens. These results suggested that morphological and morphometrical features can be used to discriminate three Adlerius species, in which one of them is proven vector Leishmania (L.) tropica in two foci of Turkey.

    Research Publications from the ATS MECOR Program in Turkiye
    Karakurt, Z; Yilmaz, O; Arikan, H; Ay, P; Demir, C; Gurkan, CG; Akgun, M; Buist, S
    Background: The American Thoracic Society (ATS) Methods in Epidemiologic, Clinical, and Operations Research (MECOR) Program aims to build research capacity in low and middle-income countries. MECOR has three levels, during which students learn to develop a research protocol and write a manuscript. MECOR Turkiye has been offered every year since 2008.Objective: The aim of this paper is to report the number and impact of published articles generated from research questions developed by students in levels 1, 2, and 3 of the ATS MECOR Program in Turkiye between 2008 and 2018.Methods: We collected the research questions developed in all levels of the ATS MECOR Program in Turkiye between 2008 and 2018. We searched Google Scholar, PubMed, Web of Science, and ResearchGate in April 2022 to see how many of these research questions were published as articles and, if published, in which journals.Results: Of the 176 research questions collected, 49 had been developed in level 1, 82 had been developed in level 2, and 45 had been developed in level 3. Of those 176 research questions, 55 (31.3%) generated articles that were accepted for publication. The frequency of published articles based on MECOR-developed research questions increased linearly as the course level in which they were developed increased (18.4% in level 1, 30% in level 2, 46.7% in level 3; P = 0.012; linear-by-linear association, P = 0.003). The median time from the development of the research question to publication was three years overall and did not differ significantly among the course levels (P = 0.36). Of the research questions developed, 43 were published in Science Citation Index or Science Citation Index Expanded-indexed journals.Conclusion: Acceptance of an article for publication is one way to measure the impact of the ATS MECOR Program. Our data describe significant research output among our participants, which increases with their length of participation in the program.

    In this article, Early Career Task Force Group members of the Turkish Thoracic Society summarize the European Respiratory Society 2020 virtual congress. Current developments in the field of respiratory diseases were compiled with the addition of sessions specific to coronavirus disease 2019 this year. Almost all of the congress sessions were examined, and the important and striking results of the congress were highlighted. Congress sessions were attended by expert researchers, and the prominent messages of each session were highlighted in short summaries. They were then grouped under relevant titles and ranked in order of meaning and relation. It was finalized by a team of researchers.

    It has been more than 3 months now since the first case of COVID-19 was reported in Turkey. Globally, the number of confirmed cases and deaths reached 9,653,048 and 491,128 respectively, as reported by 216 countries by June 27, 2020. Turkey had 1,396 new cases, 194,511 total cases, and 5,065 deaths by the same date. From the first case until today, the Turkish Thoracic Society (TTS) has been very proactive in educating doctors, increasing public awareness, undertaking academic studies, and assisting with public health policies. In the present report, social, academic, and management perspectives of the pandemic are presented under appropriate subtitles. During this critical public health crisis, TTS has once again demonstrated its readiness and constructive stance by supporting public health, healthcare workers, and the environment. This review summarizes the perspective of TTS on each aspect of the COVID-19 pandemic and casts light on its contributions.

    The novel coronavirus pandemic poses a major global threat to public health. Our knowledge concerning every aspect of COVID-19 is evolving rapidly, given the increasing data from all over the world. In this narrative review, the Turkish Thoracic Society Early Career Taskforce members aimed to provide a summary on recent literature regarding epidemiology, clinical findings, diagnosis, treatment, prevention, and control of COVID-19. Studies revealed that the genetic sequence of the novel coronavirus showed significant identity to SARS-CoV and MERS-CoV. Angiotensin-converting enzyme 2 receptor is an important target of the SARS-CoV-2 while entering an organism. Smokers were more likely to develop the disease and have a higher risk for ICU admission. The mean incubation period was 6.4 days, whereas asymptomatic transmission was reported up to 25 days after infection. Fever and cough were the most common symptoms, and cardiovascular diseases and hypertension were reported to be the most common comorbidities among patients. Clinical manifestations range from asymptomatic and mild disease to severe acute respiratory distress syndrome. Several patients showed typical symptoms and radiological changes with negative RT-PCR but positive IgG and IgM antibodies. Although radiological findings may vary, bilateral, peripherally distributed, ground-glass opacities were typical of COVID-19. Poor prognosis was associated with older age, higher Sequential Organ Failure Assessment score, and high D-dimer level. Chloroquine was found to be effective in reducing viral replication in vitro. Likewise, protease inhibitors, including lopinavir/ritonavir, favipiravir, and nucleoside analogue remdesivir were proposed to be the potential drug candidates in COVID-19 management. Despite these efforts, we still have much to learn regarding the transmission, treatment, and prevention of COVID-19.
