Item Six-year distribution pattern of hepatitis C virus in Turkey: a multicentre study(TAYLOR \& FRANCIS LTD, 2016-01-01) Altindis, Mustafa; Dal, Tuba; Akyar, Isin; Karatuna, Onur; Gokahmetoglu, Selma; Ulger, Seda Tezcan; Kulah, Canan; Uzun, Berrin; Sener, Asli Gamze; Ozdemir, Mehmet; Aydogan, Sibel; Kuskucu, Mert Ahmet; Midilli, Kenan; Otlu, Baris; Celen, Mustafa Kemal; Buruk, Kurtulus; Guducuoglu, HuseyinHepatitis C infection is a public health problem. The aim of this retrospective study was to determine the distribution of hepatitis C virus (HCV) genotypes in seven regions of Turkey, by evaluating 7002 patients with chronic HCV in a six-year period. During the 2009-2014 period, serum/plasma samples from 7002 new consecutive HCV RNA positive patients were collected. The female patients were 3867 (55.2\%). The genotype distribution of HCV patiens was evaluated by ages and years. Statistical analysis was performed by using the Mann-Whitney test and the chi(2) analysis. During the six-year period, genotype 1b was the most common genotype (67.7\%) followed by untypeable genotype 1 (7.7\%), genotype 4 (7.3\%) and genotype 3 (6.7\%). In 2014, genotype 3 was the second most common one (11.3\%) and genotype 4 was the third most common one (9.8\%). In the group with <25 years old patients, genotype 1b was most common (78.48\%, 62/79) between the years of 2009 and 2011, whereas genotype 3 (34.8\%, 86/247), between the years of 2012 and 2014. Genotype 1b was the most common in the groups between 26 and 35 years, 36 and 45 years, 46 and 55 years, 56 and 65 years. The rate of genotype 3 was increased from 4.78\% to 10.06\% and the rate of genotype 4 was increased from 1.3\% to 3.84\%, from 2009-2011 to 2012-2014. In recent years, genotypes 3 and 4 have gained importance. New therapeutic strategies and survey studies may be required for the modified HCV genotype pattern.Item `My story is like a magic wand': a qualitative study of personal storytelling and activism to stop violence against women in Turkey(TAYLOR \& FRANCIS LTD, 2021-01-01) Mwaba, Kasonde; Senyurek, Gamze; Ulman, Yesim Isil; Minckas, Nicole; Hughes, Peter; Paphitis, Sharli; Andrabi, Shazana; Ben Salem, Lobna; Ahmad, Lida; Ahmad, Ayesha; Mannell, JenevieveBackground: Telling personal stories of violence has been central to recent advocacy efforts to prevent violence against women around the world. In this paper, we explore the use of personal storytelling as a form of activism to prevent femicide in Turkey. This study is part of a broader storytelling initiative called SHAER (Storytelling for Health: Acknowledgement, Expression and Recovery) to alleviate the psychological and emotional suffering of women who have experienced gender-based violence in high-prevalence settings. Objectives: We conceptually explore personal stories of violence as a form of both distributed agency and activism. This conceptual framework is used to answer the following research question in the Turkish context: How do women use their personal stories of interpersonal violence for their own benefit (support) and that of others (activism)? Methods: Our study is based on 20 in-depth semi-structured interviews with women who have experienced violence and were purposefully recruited by the `We Will End Femicide' Platform in Istanbul. Interviews were conducted between March and August 2019. We used inductive and deductive thematic analysis to identify instances of personal storytelling at three levels: intrapersonal, relational and collective. Results: Our results show how the use of personal storytelling can provide a means of healing from experiences of violence. However, this process is not linear and is often influenced by the surrounding context including: the listener of the story, their reaction, and what social networks the woman has to support her. In supportive social contexts, personal storytelling can be an effective support for activism against violence: personal stories can provide opportunities for individuals to shape broader discourses about violence against women and the right of women to share their stories. Conclusions: Telling one's personal story of violence can both support women's agency and contribute to the collective struggle against violence against women more broadly.Item Pain management practices in the emergency departments in Turkey(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2021-01-01) Cetin, Murat; Kaya, Bora; Kilic, Turgay Yilmaz; Hanoglu, Nazife Didem; Gokhan, Servan; Eroglu, Serkan Emre; Akar, Sakine Neval; Cekic, Ozgen Gonenc; Polat, Dicle; Ustsoy, Emre; Cinar, Orhan; Yilmaz, SerkanOBJECTIVES: This study aimed to evaluate pain management practices in the emergency departments (EDs) in Turkey and to evaluate the prevalence and etiologies of oligoanalgesia to identify possible improvement strategies.
METHODS: This multicenter cross-sectional observational study was conducted in 10 tertiary care hospitals in Turkey. Patients who were admitted to the ED with pain chief complaints were included in the study. Both patients and physicians were surveyed with two separate forms by the research associates, respectively. The patient survey collected data about the pain and the interventions from the patients' perspective. The pain was evaluated using the Numerical Rating Scale. The physician survey collected data to assess the differences between study centers on pain management strategies and physician attitudes in pain management.
RESULTS: Ten emergency physicians and 740 patients (male/female: 365/375) enrolled in the study. The median pain score at admission at both triage and ED was 7 (interquartile range: 5-8). The most frequent type of pain at admission was headache (n = 184, 24.7\%). The most common analgesics ordered by physicians were nonsteroidal anti-inflammatory drugs (n = 505, 67.9\%), and the most frequent route of administration was intramuscular injection (n = 396, 53.2\%). About half of the patients (n = 366, 49.2\%) received analgesics 10-30 min from ED admission. The posttreatment median pain score decreased to 3 (P < 0.001). About 79.2\% of patients did not need a second analgesic administration (n = 589), and opioid analgesics were the most frequently administered analgesic if the second application was required. Physicians prescribed an analgesic at discharge from the ED in 55.6\% of the patients (n = 414) and acute pain was present in 7.5\% (n = 56) of the patients.
CONCLUSION: Our study on the pain management practices in the EDs in Turkey suggested that high rate of intramuscular analgesic use and long emergency room stay durations are issues that should constitute the focus of our quality improvement efforts in pain management.Item Determination of Antimony Resistance Mechanism of Leishmania tropica Causing Cutaneous Leishmaniasis in Turkey(ANKARA MICROBIOLOGY SOC, 2020-01-01) Ozbilgin, Ahmet; Zeyrek, Fadile Yildiz; Guray, Melda Zeynep; Culha, Gulnaz; Akyar, Isin; Harman, Mehmet; Ozbel, Yusuf; Ertabaklar, Hatice; Cavus, Ibrahim; Gunduz, CumhurWorld Health Organization reported that approximately one billion people are at risk in endemic areas, one million cases of cutaneous leishmaniasis (CL) and approximately 300,000 cases of visceral leishmaniasis (VL) were reported per year in the last five years. The number of deaths due to VL is reported to be approximately 20,000 per year. Approximately 2500 cases/year have been reported as CL, caused by Leishmania tropica and Leishmania infantum, in Turkey. The significant increase observed in many cities mainly in the provinces of Mediterranean and Aegean regions in cases and foci in recent years, suggests that there may be an increase in this infections in the following years as well. In Turkey, the causative agent of CL is L.tropica and meglumine antimoniate is used in the treatment of CL. We aimed to determine antimony resistance genes specific for L.tropica by comparing the gene and protein expressions of antimony-resistant and non-resistant L.tropica strains. Ltropica isolates obtained from 3 CL patients without antimonate resistance from Aegean, Mediterranean and Southeastern regions of Turkey were provided to transform into 3 resistant isolates against meglumine antimony in the laboratory conditions. Gene expression alterations by microarray methodItem Diversity of Leishmania Strains Isolated from Cutaneous Leishmaniasis Patients in Turkey and its Reflection to Clinics in Mice Model(ANKARA MICROBIOLOGY SOC, 2020-01-01) Ozbilgin, Ahmet; Culha, Gulnaz; Guray, Melda Zeynep; Zeyrek, Fadile Yildiz; Akyar, Isin; Toz, Seray; Ural, Ipek Ostan; Kurt, Ozgur; Kocagoz, Tanil; Cavus, Ibrahim; Gunduz, CumhurAlthough asexual reproduction has been attributed to Leishmania species, genetic exchange has recently been demonstrated, which helped emerging of hybrid isolates. Situated on the crossroads between three continents, Leishmania hybrids may be present in Turkey. In Turkey, visceral leishmaniasis caused by Leishmania infantum is less common, while cutaneous leishmaniasis (CL) caused by Leishmania tropica and L.infantum could reach 2500 reported cases a year. Our aim was to investigate genetic variability of local Leishmania species and presence of hybrid Leishmania strains in Turkey. Twenty CL patients from Sanliurfa and Hatay, where only L.tropica and both L.tropica and L.infantum cause CL, respectively, were registered equally. All isolates were assessed with real-time polymerase chain reaction (Rt-PCR), isoenzyme analysis, gene sequencing, two-dimensional gel electrophoresis (2D-PAGE) and MALDI-TOF/TOF-MS followed by in vivo analyses on mouse model. Identification of differentially expressed proteins was performed. These proteins were confirmed by sequence analysis. All isolates from Sanliurfa were found to be L.tropica which caused cutaneous infection in mice. However, one of 10 isolates from Hatay was found as Leishmania major which caused cutaneous infection. Five isolates were found as L.tropica with Rt-PCR and gene sequencing, one of which had one different protein from the reference L.tropica strain and caused cutaneous infection. Four of the five isolates had five different proteins compared to reference strain and caused both cutaneous and visceral infections. Remaining four isolates showed double melting curves in Rt-PCR, which were concordant with L.tropica and L.infantum. Their sequencing and isoenzyme analyses indicated them as L.infantum. They had six different proteins compared to reference L.infantum strain and caused cutaneous and visceral infections. It is concluded that the isolates with different proteins were hybrid Leishmania species. In the present study, outcomes of the proteomics, genomics, clinical manifestations and tissue tropism on animal models were evaluated together for the first time. In addition to L. tropica and L.infantum, L.major was identified as a causative agent for CL and hybrids of Linfantum/tropica were also shown to be present.Item Perceptions of Students of a Medical School on Combined Health Warnings in Plain Packs(AVES, 2021-01-01) Yasin, Yesim; Aykac, NiluferOBJECTIVE: Turkey has recently adopted the regulation of plain and standard packaging for tobacco products and introduced newly designed combined health warnings. In this study, we aimed to reveal how the new combined health warnings are perceived among medical students. MATERIAL AND METHODS: The study was descriptive and the data were collected by a 3-part questionnaire. The first part covered demographic characteristics, the second part was designed to measure the saliency of the combined health warnings, and the third part evaluated their effect on the motivation to quit. RESULTS: Out of 484 students of medicine, 287 (59\%) were included in the studyItem Persistent Ambient Air Pollution in Turkey: A 4-Year Analysis(AVES, 2021-01-01) Aykac, Nilufer; Yasin, YesimOBJECTIVE: Ambient air pollution is an important cause of morbidity and mortality for both individual and public health. The major contaminant that creates air pollution in Turkey is particulate matter. This study aims to demonstrate Turkey's air quality in terms of particulate matter in the last 4 years. MATERIAL AND METHODS: In this descriptive study, the public data of the National Air Quality Monitoring Network between the years 2016 and 2019 were analyzed for particulate matter (PM10). Stations with less than 75\% data throughout the year were excluded from the evaluation while calculating the annual average values. The averages of the years were compared statistically with each other. RESULTS: For 111 stations that made sufficient measurements for 4 years, the annual median value of particulate matter remained constant in 12 stations (10.8\%), increased in 26 stations (23.4\%), and decreased in 73 stations (65.7\%). The level of air pollution at 18 stations has been sustained for 4 years. It has been observed that there is no significant improvement in the criterion that the daily average PM10 level should not be higher than 50 mu g/m(3) for more than 35 days, and pollution is detected above the limit value permitted by the World Health Organization in all provinces and stations except a few provinces every year. Finally, during the 4-year observation, the number of stations that did not make sufficient measurements throughout the year has been found to increase over the years. CONCLUSION: Our data reveal that the air pollution attributable to particulate matter in Turkey between the years 2016 and 2019 did not regress prominently. On the contrary, air pollution has been found to gain permanency in certain provinces, and air quality monitoring has been inadequate due to insufficient measurement activities of some of the stations.Item History of Lung Transplantation(BILIMSEL TIP PUBLISHING HOUSE, 2016-01-01) Dabak, Gul; Senbaklavaci, OmerHistory of lung transplantation in the world can be traced back to the early years of the 20th century when experimental vascular anastomotic techniques were developed by Carrel and Guthrie, followed by transplantation of thoracic organs on animal models by Demikhov and finally it was James Hardy who did the first lung transplantation attempt on human. But it was not until the discovery of cyclosporine and development of better surgical techniques that success could be achieved in that field by the Toronto Lung Transplant Group led by Joel Cooper. Up to the present day, over 51.000 lung transplants were performed in the world at different centers. The start of lung transplantation in Turkey has been delayed for various reasons. From 1998 on, there were several attempts but the first successful lung transplant was performed at Sureyyapasa Hospital in 2009. Today there are four lung transplant centers in TurkeyItem ASSESSMENT OF THE TURKEY'S ELECTRIC POWER POLICIES IN TERMS OF SUSTAINABILITY(VINCA INST NUCLEAR SCI, 2014-01-01) Atis, Selcuk; Onat, Nevzat; Guney, K. R. IrfanThis study, using statistical data published by the Turkish Electricity Transmission Company, analyzes key parameters such as installed capacity and energy demand growth rates, investment plans and emission rates, taking into consideration the expected increase in use through the year 2023. The results of the analyses were compared to relevant data from around the world. The weight of domestic and especially renewable resources in investment plans for the next 10 years was discussed. Recommendations for an investment plan to support sustainable development in Turkey are listed. Consequently, the lack of investment in domestic and renewable energy projects decreases the competitive power of Turkey vis-a-vis Organisation for Economic Co-Operation and Development countries in terms of many parameters. For a sustainable development, the country must make significant changes in its foreign-dependent energy production policies. Any future policies must encourage supplying local resources to meet the continuously increasing demand. Qualifications for incentive mechanisms applied to investments in renewable energy should be developed. The impact of the private sector on the installation of new plants must also be increased by quickly completing the privatization processItem IODINE DEFICIENCY IN PREGNANT WOMEN LIVING IN WESTERN TURKEY (EDIRNE)(EDITURA ACAD ROMANE, 2016-01-01) Celik, H.; Guldiken, S.; Celik, O.; Taymez, F.; Dagdeviren, N.; Tugrul, A.Objective. Data about iodine status in pregnant women in Turkey is not sufficient. We aimed to determine the iodine status, goiter prevalence, iodized salt consumption among first trimester pregnant women living in Edirne. Design and Setting. Cross-sectional study was performed on pregnant women living in Edirne. Subjects and Methods. A total of 275 pregnant women in their first trimester were examined regarding iodized salt use, median urinary iodine concentration (UIC), presence or absence of goitre and thyroid function. Goitre status was determined by palpation. Participants filled out a questionnaire, which included questions regarding sociodemographic features, iodized salt consumption, knowledge, and behavior regarding iodine deficiency. UIC was measured using colorimetric method based on Sandell-Kolthoff reaction. Thyroid hormones and TSH were measured by chemiluminescence immunoassays. Results. While the proportion of iodized salt use was 96.6\%, UIC was below 150 mu g/L in 88.4 \% of the women. The median UIC was 77 mu g/L, indicating insufficient iodine intake. Total goitre rate was 19.3\%. Conclusions. Our study shows that iodine deficiency is a serious problem among pregnant women in Edirne. We suggest that pregnant women living in Edirne should be supplemented by iodine-containing preparations in addition to iodized salt.
