This study aimed to investigate the characteristics and outcomes among PD patients and compare them with \rmatched hemodialysis (HD) patients and a control group without kidney disease.\rMethods: We included 18 PD patients and consecutive age- and gender-matched 18 HD and 18 patients without kidney \rdisease (control group) registered into the Turkish Society of Nephrology database including 1301 COVID-19 patients. We \rcompared demographic, clinical, radiological, laboratory data, and outcomes namely intensive care unit (ICU) admission, \rmechanical ventilation, mortality, and composite outcome (death and/or ICU admission).\rResults: ICU admission, mechanical ventilation, and mortality rates in PD patients (27.8%, 22.2%, and 22.2%, respectively) \rand the HD group (16.7%, 11.1%, and 16.7%, respectively) were higher than the control group (11.1%, 11.1%, and 5.6%, \rrespectively), but intergroup comparison did not reveal difference. A total of 11 (20.3%) patients had composite outcome \r(6 PD patients, 3 HD patients, and 2 patients in the control group). In Cox regression analysis, higher age and higher CRP level were related to increased risk of composite outcome. Adjusted rate of composite outcome in PD group was significantly higher than \rthe control group (P = .050). This rate was similar in HD and control groups (P = .30).\rConclusions: Combined in-hospital mortality and/or ICU admission of PD patients with COVID-19 was significantly higher than the control \rpatients. There is a need for careful surveillance of PD patients for infection signs and prompt treatment of COVID-19.Article False Information About Covid-19 Vaccination in Turkey: Analysis of Twitter Posts(2022) Özoran, Beris Artan; Seyıdov, IlgarThe COVID-19 pandemic has affected the world socially, culturally, economically, and politically. Struggling with the COVID-19 virus has become the focal point of the countries. As many studies are being conducted, and new treatment methods are being discussed, the vaccination process continues worldwide. According to the current statistics, 63% of the world population has been already fully vaccinated. During this period, along with the true information, many false information facts and materials proliferated which lead to the reluctance of individuals to be vaccinated. As a result of it, the virus exposes to mutation and more serious cases emerge worldwide. In this context, this study aims to analyze false information Tweets regarding vaccination in Turkey. As Turkey is one of the top countries with the highest cases and the medium-scaled (68%) level of vaccination worldwide, the study findings will help to understand the main motives of anti-vaccination by focusing on false facts. A two-step methodology was followed in the research. First, data collection was done through Twitter API and then, the analysis was conducted using the Orange Data Mining Program and content analysis. Propaganda is one of the interesting results as the most-shared false information type. On the other hand, while “the denial of the epidemic” was the most-focused theme, “stop insisting on PCR” and “pandemic is over” were the most-emphasized discourses in the Tweets.Article Citation - WoS: 3Citation - Scopus: 4Identification of Bacterial Diversity of Bee Collected Pollen and Bee Bread Microbiota by Metagenomic Analysis(Aves, 2022) Arserim Ucar, Dilhun Keriman; Yurt, Mediha Nur Zafer; Tasbasi, Behiye Busra; Acar, Elif Esma; Yegin, Zeynep; Ozalp, Veli Cengiz; Sudagidan, Mert; Uçar, Dilhun Keriman Arserim; Ozalp, Cengiz; Arserim-uçar, Dılhun KerimanThis study investigated the bacterial diversities of bee-collected pollen and bee bread of Apis mellifera in Turkey. The bacterial community structure of 14 bee pollen from Bingol, Konya, and Hakkari and 11 bee bread samples from Bingol were studied using 16 S rRNA amplicon sequencing and metagenomic analysis. The dominant bacterial phylum in pollen and bee bread samples was Firmicutes, followed by Proteobacteria. In pollen and bee bread samples, Bacillaceae, Clostridiaceae, Enterococcaceae, and Enterobacteriaceae were identified as dominant bacterial families. At the genus level, Bacillus, Clostridium sensu stricto, and Enterococcus were dominant bacteria in both pollen and bee bread samples. The most abundant species was Clostridium perfringens in both pollen and bee bread samples. Escherichia vulneris, Enterococcus faecalis, Bacillus cereus, Enterococcus casseliflavus, and Cronobacter malonaticus were identified with high reads in pollen samples. In bee bread samples, E. faecalis, Clostridium bifermentans, and Pantoea calida were abundant bacterial species. Alpha diversity showed that pol-3 sample had the highest diversity. Beta-diversity plots separated the pollen samples into four main groups and bee bread samples into three main groups. Our results indicated that the culture-independent metagenomic analysis will be a valuable tool for determining the microbial diversity of bee products produced in Bingol-Turkey one of the important centers of apiculture.Article İnkontinans İlişkili Dermatit Yönetiminde Hemşirelerin Bilgi, Tutum ve Uygulamalarını Değerlendirme Ölçeği: Türkçe Geçerlik ve Güvenirlik Çalışması(2022) Sönmez, Münevver; Korkmaz, Serap; Kısacık, Öznur GürlekAmaç: Çalışma, İnkontinans İlişkili Dermatit Yönetiminde Hemşirelerin Bilgi, Tutum ve Uygulamalarını Değerlendirme Ölçeği Türkçe formunun geçerlik ve güvenirliğini incelemek amacı ile gerçekleştirildi.

There is a need to identify the complex interplay between various physiological mechanisms in primary ciliary dyskinesia (PCD) and cystic fibrosis (CF). The study investigated the interaction between respiratory function, exercise capacity, muscle strength, and inflammatory and oxidant/antioxidant responses in patients with PCD and CF. Methods. The study included 30 PCD patients, 30 CF patients, and 29 age and sex-matched healthy subjects. Exercise capacity was assessed using the modified shuttle walk test (MSWT). Handgrip strength (HGS) was used to evaluate general muscle strength. Oxidative stress-inflammatory parameters were also assessed. Pulmonary function test was performed by spirometry. Regarding the forced expiratory volume in 1 second (FEV1) 1 ) z-score, patients with PCD and CF were subdivided into normal, mild, and severe/moderate groups. Results. Forced vital capacity (FVC) z-scores were lower in PCD and CF patients than controls. FEV1, 1 , FEV1/ 1 / FVC, peak expiratory flow (PEF), and forced mid expiratory flow (FEF 25-75% ) z-scores were lower in PCD than in the other groups. HGS was lower in both mild PCD and normal CF patients relative to the controls. MSWT distance was lower in severe/moderate PCD patients than controls. Catalase (CAT), glutathione S-transferase (GST), glutathione peroxidase (GPx), and malondialdehyde (MDA) levels did not differ significantly among the study groups, but superoxide dismutase (SOD) level in severe/moderate PCD, and glutathione (GSH) level in normal CF were higher than in controls. Interleukin-6 (IL-6) level was higher in patients with normal PCD and CF compared to the controls. IL-1 beta level was higher in PCD compared to controls. Additionally, correlations among these parameters were also determined in some patient groups. Conclusion. Homeostasis related to respiratory function, aerobic performance, muscle strength, inflammatory response, and oxidant/antioxidant balance were affected in PCD and CF. Evaluating these mechanisms together may contribute to elucidating the pathophysiology of these rare diseases.Review Hepatit B İnfeksiyonlarının İmmünopatogenezi(Bilimsel Tip Yayinevi, 2019) Tülek, NeclaHepatit B infeksiyonları tüm dünyada majör sağlık problemleri arasında olup, siroz ve hepatoselüler karsinomanın en önemli nedenidir.Tedavide gelişmelere rağmen henüz kronik hepatit B infeksiyonunda kür sağlanamamaktadır. Hepatit B infeksiyonlarında klinik sonuçinfeksiyonun alınma yaşı, viral yük ve konağın immün yanıtına bağlıdır. Akut hepatitlerde klinik seyir subklinik hastalıktan, anikterikhepatite, ikterik hepatite ve fulminant hepatite kadar değişebilirken, kronik hepatitlerde hastalığın seyri asemptomatik inaktif durumdankronik hepatite, siroz ve hepatoselüler karsinomaya kadar değişebilir. Hepatit B virüsü hepatositlerde sitopatik olmayarak çoğalır veklinik sendromların çoğu immün yanıt ile ilişkilidir. İmmün sistem aktivasyonu virüsün eliminasyonunu sağladığı gibi karaciğer hasarınada neden olur. Hepatit B patogenezinde hücresel immün yanıt özellikle de CD8+ T hücreler santral olmasına rağmen immün sistemindiğer komponentleri de katkıda bulunur. Kronik hepatitli hastalarda hem doğal hem de adaptif immün yanıt zayıflamış ve T hücreyanıtı tükenmiş durumdadır. İmmünopatolojideki mekanizmaların daha iyi anlaşılması, yeni etkin tedavi stratejilerinin geliştirilmesindeyararlı olacaktır.Article Citation - Scopus: 5Real-World Data From Turkey: Is Sofosbuvir/Ledipasvir With or Without Ribavirin Treatment for Chronic Hepatitis C Really Effective?(AVES, 2021) Demirtürk,N.; Aygen,B.; Çelik,İ.; Mıstık,R.; Akhan,S.; Barut,Ş.; Doğan,N.; Karakeçili, Faruk; Asan, Ali; Özel, Selcan Arslan; Ersöz, Gülden; Yıldız, Orhan; Şimşek, Sümeyra; Tarakçı, HüseyinBackground: In this study, we aimed to investigate the efficacy and safety of sofosbuvir-based therapies in the treatment of chronic hepatitis C in real-world clinical practice. Methods: Data from patients with chronic hepatitis C treated with SOF/LDV ± RBV or SOF/RBV in 31 centers across Turkey between April 1, 2017, and August 31, 2018, were recorded in a nationwide database among infectious disease specialists. Demographics, clinical, and virological outcomes were analyzed. Results: A total of 552 patients were included in the study. The mean age of the patients was 51.28 ± 14.2, and 293 (55.8%) were female. The majority had HCV genotype 1b infection (65%), 75.04% of the patients underwent treatment, and non-cirrhosis was present at baseline in 381 patients (72.6%). SOF/LDV ± RBV treatment was given to 477 patients and 48 patients received SOF/RBV according to HCV genotype. The total SVR12 rate was 99% in all patients. Five patients experienced disease relapse during the study and all of them were genotype 2. In patients infected with HCV GT2, SVR12 was 77.3%. SVR was 100% in all patients infected with other HCV genotypes. All treatments were well tolerated by patients without causing severe adverse events. Side effects and side effects-associated treatment discontinuation rates were 28.2% and 0.4%, respectively. Weakness (13.7%) was the common side effect. Conclusion: The present real-world data of 525 patients with HCV genotypes 1, 1a, 1b, 3, 4, and 5 who underwent SOF/LDV ± RBV treatment in Turkey demonstrated a high efficacy and safety profile. HCV GT2 patients should be treated with more efficacious treatment. © Copyright 2021 by The Turkish Society of Gastroenterology • Available online at turkjgastroenterol.orgArticle Herpes Zoster Hastalarının Demografik ve Klinik Özelliklerinin Değerlendirilmesi(Selcuk University, 2023) Demirci Saadet, E.; Hasanbeyzade, S.; Hasanbeyzade, Sabir; Saadet, Elif DemırcıBackground: Herpes zoster is a disease that is more frequently seen in people aged over 50 years and negatively affects the quality of life due to the development of post-herpetic neuralgia. This study aimed to investigate the demographic and clinical characteristics of patients diagnosed with herpes zoster. Methods: In this cross-sectional study, the data of patients who were followed up with a diagnosis of herpes zoster at the dermatology department between 2013 and 2020 were retrospectively examined. Results: Of 440 patients, 252 (57.3%) were female and 188 (42.7%) were male. The mean age was 48.9±18 (4-94) years. The most common localization was the thoracic region at a rate of 35.5% and the lumbar region at a rate of 21.4%. Disseminated and ophthalmic zoster were more common in elderly patients (p<0.001). The most common comorbidities were hypertension (HT)+coronary artery disease (CAD) (12.6%), cancer (10.3%), and diabetes+HT (5.9%). Severe pain was observed in 19.7% of the patients and was more common in women (p=0.016). The rate of moderate and severe pain was high in the patients with HT+CAD and cancer (p˂0.001). Post-herpetic neuralgia was observed in 15.3% of the patients aged over 50. Conclusions: Herpes zoster is especially common in adults. Since it causes acute pain and can lead to postherpetic neuralgia development, risky patient groups should be more carefully followed up and treated. © 2023, Selcuk University.

Materials and Methods: This multi-center point-prevalence study was conducted on inpa- tients, divided into two groups as ‘fully’ and ‘partially’ vaccinated according to COVID-19 vaccination status. Results: Totally 516 patients were included in the study. The median age was 65 (55-77), and 53.5% (n=276) of the patients were male. Hypertension (41.9%, n=216), diabetes mel- litus (DM) (31.8%, n=164), and coronary artery disease (CAD) (16.3%, n=84) were the pre- dominant comorbidities. Patients were divided into two groups ICU (n=196) and non-ICU (n=301). Hypertension (p=0.026), DM (p=0.048), and congestive heart failure (CHF) (p=0.005) were significantly higher in ICU patients and the median age was younger among non-ICU patients (p=0.033). Of patients, 16.9% (n=87) were fully vaccinated, and this group’s need for ICU support was statistically significantly lower (p=0.021). Conclusion: We conclude that older age, hypertension, DM, CHF, and being partially vacci- nated were associated with the need for ICU support. Therefore, all countries should con- tinuously monitor post-vaccination breakthrough COVID-19 infections to determine the national booster vaccine administration approach that will provide vulnerable individuals the highest protection.
