    Background/Aims: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. Material and Methods: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)+/- ribavirin (RBV) ombitasvir/paritaprevir/ritonavir +/- dasabuvir (PrOD)+/- RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. Results: SVR12 was achieved in 92.8\% of the patients (4,040/4,352) according to intention-to-treat and in 98.3\% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2\%-100\%) and genotypes (95.6\%-100\%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90 +/- 54.60 U/L to 17.00 +/- 14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51 +/- 4.54 to 7.32 +/- 3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0 +/- 16.0 weeks post-treatment. Higher initial MELD score (odds ratio {[}OR]: 1.92, 95\% confidence interval {[}CI]: 1.22-2.38

    Objective: There is no other screening program close to the success rate of PAP test. Cervical cytology constitutes a large workload so that quality control in cervical cytology is important for the quality assurance of pathology laboratories. Material and Method: In this study, we collected the cervical cytology results from all over Turkey and discussed the parameters influencing the quality of the PAP test. The study was conducted with Turkish gynaecopathology working group and 38 centers (totally 45 hospitals) agreed to contribute from 24 different cities. The study was designed to cover the cervical cytology results during 2013. The results were evaluated from the data based on an online questionnaire. Results: The total number of Epithelial Cell Abnormality was 18,020 and the global Epithelial Cell Abnormality rate was 5.08\% in the total 354,725 smears and ranging between 0.3\% to 16.64\% among centers. The Atypical squamous cells/Squamous intraepithelial lesion ratios changed within the range of 0.21-13.94 with an average of 2.61. When the centers were asked whether they performed quality assurance studies, only 14 out of 28 centers, which shared the information, had such a control study and some quality parameters were better in these centers. Conclusion: There is an increase in the global Epithelial Cell Abnormality rate and there are great differences among centers. Quality control studies including the Atypical squamous cells/Squamous intraepithelial lesion ratio are important. Corrective and preventive action according to quality control parameters is a must. A cervical cytology subspecialist in every center can be utopic but a dedicated pathologist in the center is certainly needed.

    (BMC, 2020-01-01) Idilman, Ramazan; Razavi, Homie; Robbins-Scott, Sarah; Akarca, Ulus Salih; Ormeci, Necati; Kaymakoglu, Sabahattin; Aygen, Bilgehan; Tozun, Nurdan; Guner, Rahmet; Bodur, Hurrem; Lazarus, Jeffrey V.
    Background In 2016, WHO passed the Global Health Sector Strategy on Viral Hepatitis (GHSS), calling for its elimination by 2030. Two years later, Turkey approved a strategy to reach the WHO targets. This study reports new national prevalence data, breaks it down by subpopulation, and models scenarios to reach HCV elimination. Methods Literature was reviewed for estimates of HCV disease burden in Turkey. They were discussed with stakeholders and used as inputs to develop a disease burden model. The infected population was estimated by sequelae for the years 2015-2030. Three scenarios were developed to evaluate the disease burden in Turkey: a Base 2017 scenario, representing the current standard of care in Turkey

    Recommendations for the selection of techniques and components used in congenital heart surgery in Turkey
    (BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2012-01-01) Undar, Akif; Haydin, Sertac; Erek, Ersin; Yivli, Perihan; Odemis, Ender; Agirbasli, Mehmet; Alkan-Bozkaya, Tijen; Turkoz, Ayda; Turkoz, Riza; Sasmazel, Ahmet; Karaci, Ali Riza; Cicek, Ali Ekber; Yalcinbas, Yusuf; Akcevin, Atif; Sarioglu, Tayyar; Bakir, Ihsan
    There is no standard for the selection of technical and mechanical components (heart-lung machine system, oxygenator, arterial and venous cannulae, arterial filter and other specifically-designed components and devices) used in cardiopulmonary bypass in Turkey. The cost of the component plays a significant role in the selection, as well as the preference of the facility. Only a limited number of hospitals decide which components to be used based on scientific data. Studies have confirmed that selected novel techniques and components having no basis of scientific justification may pose risk for the life of the patient in the short- and long-term. The objectives of this study are to show how to use quality-control procedures and scientific data for the selection of novel techniques and components and to share, also, recent techniques experienced to minimize the complication risk after surgery.

    Radiotherapy Equipment and Workforce in Turkey
    (KARE PUBL, 2021-01-01) BecerIr, Hatice Bilge; Gurdalli, Salih; Yapici, Bulent; Alkaya, Fadime; cakir, Aydin; Yaray, Kadir; Gursoy, Tamer Oguz
    OBJECTIVE Radiotherapy is a costly treatment that requires the proper use of human and financial resources. In any country, the radiation therapy equipment and workforce should be well planned for the appropriate use of resources and radiotherapy treatments. For proper planning, the current situation should be assessed and prepared for the targets to be achieved. This study aims to determine the current status of radiotherapy devices and the workforce in Turkey. METHODS Questions were sent to 141 centers to evaluate the number of devices, technical specifications, date of manufacture and the number of radiation oncologists, medical physicists, and radiotherapy technicians by Turkish Medical Physics Association. The responses from the centers were analyzed by region and compared with the situation in other countries. RESULTS The data collected in the study are from December 2019. The rate of radiotherapy devices in Turkey according to population is estimated to be 3.14 megavoltage (MV) external devices per 1 million people. The distribution is not homogeneous in all regions. The highest value is 4.59 in the Central Anatolia region, and the lowest is 0.78 in the Eastern Anatolia region. For each MV device, on average, there are 1.58 specialists in medical physics. CONCLUSION Our study has shown that Turkey has made significant progress in terms of radiotherapy equipment and workforce in the past decade. Nevertheless, although Turkey did not reach the standards of high-income European countries, it is comparable to middle-income countries.

    The state of ethics education at medical schools in Turkey: taking stock and looking forward
    (BMC, 2020-01-01) Kavas, Mustafa Volkan; Ulman, Yesim Isil; Demir, Figen; Artvinli, Fatih; Sahiner, Melike; Demiroren, Meral; Senyurek, Gamze; Pakis, Isil; Bakirci, Nadi
    Background Ethics teaching is globally considered an essential part of medical education fostering professionalism. It does not only provide knowledge for good clinical conduct, but also trains medical students as virtuous practitioners. Although Turkey has had a considerable experience in ethics education of healthcare professionals, the general state of ethics curricula at medical schools in Turkey is unknown. Methods The purpose of this study was to collect comprehensive data about the ethics education programs at medical schools in Turkey. To this aim, we designed a cross-sectional descriptive questionnaire survey which focuses on the content, teaching years, teaching, assessment and evaluation methodologies, workforce and infrastructure. We delivered the questionnaire to all medical schools in Turkey. Seventy-nine medical schools participated in this study (response rate: 78\%). Results Although most institutions had an undergraduate ethics curriculum (91.1\%), the findings suggest deficiency of teaching personnel (34.2\% had no instructors). Furthermore, the distribution and composition of the workforce was imbalanced. The content varies largely among institutions. Medical schools with an ethics department were more likely to diversify teaching topics. However, ethics education was largely based on the four-principle approach. The content was usually conveyed to students theoretically. Around 90\% of schools had classroom lectures. It is the only method used at one-third of them. Clinical ethics education was mostly lacking. Multiple-choice tests were widely used to assess and evaluate student attainments (86.1\%). Conclusions Staff qualified to teach ethics and ethics education integrated into the six-year medical curriculum given by a multidisciplinary team are urgent necessities. Considering teaching, assessment and evaluation methodologies used, most medical schools seem to fall short of fostering students to develop ethical attitudes. Endeavors aiming for modern topics should be encouraged. As the organization ethics education change continuously, we think that a platform for monitoring ethics education at medical schools in Turkey should be established. Such a body would help ethics instructors to network and find solutions to current problems and build shared wisdom.

    Lived experiences of people living with HIV: a descriptive qualitative analysis of their perceptions of themselves, their social spheres, healthcare professionals and the challenges they face daily
    (BMC, 2021-01-01) Senyurek, Gamze; Kavas, Mustafa Volkan; Ulman, Yesim Isil
    Background: Human immunodeficiency virus (HIV) infection rates have been gradually increasing in Istanbul, Turkey. Many people living with HIV (PLWH) here encounter difficulties, for example, in adapting to the chronic disease and obtaining continuous access to healthcare services. In this study, we aimed to explore the challenges PLWH face in their daily lives and understand their perceptions of themselves, healthcare professionals and services, and their social spheres via their expressed lived experiences in the healthcare setting. Method: Individual semi-structured in-depth interviews were conducted face-to-face with 20 PLWH in Istanbul. All the interviews were voice-recorded and transcribed verbatim except one, upon participant request, for which the interviewer took notes. These logs and the interviewer's notes were analyzed thematically using the inductive content analysis method. Results: The themes concerned experiences in three distinct contexts: 1) Interactions with healthcare providers
