    Acil Pandemi Polikliniğine Başvuran ve COVID-19 Şüphesiyle Değerlendirilen Hastaların Retrospektif Analizi
    (2021) Altınsoy, Hasan Baki; Naldemir, İbrahim Feyyaz; Çalışkan, Emel; Şahin, İbrahim Ethem; Karadağ, Mehmet; Boğan, Mustafa
    Amaç: SARS-CoV-2 olarak adlandırılan yeni tip korona virüsün neden olduğu COVID-19 pandemisi halen tüm dünyada etkisini sürdürmektedir. COVID-19 etkeninin neden olduğu semptomlar diğer solunum yolu etkenlerine benzese de toplumsal etkileri oldukça şiddetli ve farklı seyretmektedir. Bu çalışma hastanemizin acil servis girişinde oluşturulan acil pandemi polikliniğine başvuran ve COVID-19 ön tanısıyla tetkik edilen hastaların analizinin yapılması amacıyla planlanmıştır.Gereç ve Yöntemler: Acil pandemi polikliniğine başvurmuş 16 yaş ve üzeri hastalardan, ateş, öksürük, nefes darlığı şikayetleri olup COVID-19 şüphesiyle polimeraz zincir reaksiyonu (PZR) testi için üst solunum yolundan sürüntü örneği alınmış ve Toraks bilgisayarlı tomografisi (TBT) yapılmış olanlar dahil edilmiştir. Bulgular: PZR testi pozitif ve negatif olan hastaların geliş şikayetleri karşılaştırıldığında, iki grubun da benzer şikayetlere sahip olduğu görülmüştür. PZR testi pozitif hastaların WBC sayıları (5748,39 ± 1547,01), nötrofil sayıları (3650,32 ± 1355,58), lenfosit sayıları (1467,74 ± 472,3) ve platelet sayıları (224,65 ± 76,01); PZR testi negatif olan hastalardan daha düşük bulunmuştur.Sonuç: COVID-19 PZR testi pozitif hastalarda daha düşük WBC, nötrofil ve lenfosit sayısı tespit edilmiştir. Toraks bilgisayarlı tomografi bulguları olan PZR pozitif vakalarda platelet sayısı daha düşük ve CRP değeri daha yüksek izlenmiştir. Bu verilerin özellikle ileri tanı testlerinin olmadığı veya geç sonuçlandığı sağlık kuruluşları için hastalıktan şüphelenme ve erken izolasyon için yol gösterici olabileceğini düşünmekteyiz.

    (2021) Dokur, Mehmet; Baysoy, Nüket Güler; Uysal, Betül Borku; Karadağ, Mehmet; Demirbilek, Mahmut
    Objective: Altmetrics, or alternative-metrics, have\rrecently emerged as a web-based metrics measuring the\rimpact of an individual article in social media accounts\rwith an emphasis on the public attention/engagement\rwith the research output. Aim of this study is to perform\rmid-2020 altmetric analysis of top-100 articles about\rCOVID-19 that provoked the most online attention.\rMethods: Altmetric Explorer search was performed\rin June 3th ,2020. After ranked by altmetric attention\rscore (AAS: an automatically calculated weighted count\rof all of the attention a research output has received in\rsocial media), articles that are not related by COVID-19\rwere excluded and the first-100 COVID-19-related\rarticles were analyzed. Variables evaluated were (I)\rAAS, (II) dimensions-badge (interactive visualizations\rthat showcase the citation data origins for individual\rpublications), (III) month of publication, (IV) distribution\rof web-sources, (V) demographic-breakdown type\rdistributions of citations, (VI) geographic-breakdown\rtype distributions of citations, (VII) level-of-evidence\r(decided using SIGN-Criteria) (VIII) Q-categories ofscientific journals, and (IX) h-index. Descriptive and\rcorrelational statistics were performed. Kruskal-Wallis\rtest was used for AAS and dimensions-badge value\rcomparisons while post-hoc analyses were performed\rby Dunn test. Spearman correlation coefficients were\rcalculated to detect linear relationship between\rnumerical variables. Analyses were performed by SPSS-\r23.0 and p<0.05 was considered statistically significant.\rResults: Most (74%) of the disseminated articles\rwere published in Q1-journals while evidence levels were\rmostly level-3/level-4.

    An altmetric study: Social attention based evaluation of top-100 publications about the COVID-19 pandemic from notification of the first case to the 6th month
    (Refik Saydam National Public Health Agency (RSNPHA), 2021) Dokur, Mehmet; Baysoy, Nüket Güler; Uysal, Betül Borku; Karadağ, Mehmet; Demirbilek, Mahmut
    Objective: Altmetrics, or alternative-metrics, have recently emerged as a web-based metrics measuring the impact of an individual article in social media accounts with an emphasis on the public attention/engagement with the research output. Aim of this study is to perform mid-2020 altmetric analysis of top-100 articles about COVID-19 that provoked the most online attention. Methods: Altmetric Explorer search was performed in June 3th,2020. After ranked by altmetric attention score (AAS: an automatically calculated weighted count of all of the attention a research output has received in social media), articles that are not related by COVID-19 were excluded and the first-100 COVID-19-related articles were analyzed. Variables evaluated were (I) AAS, (II) dimensions-badge (interactive visualizations that showcase the citation data origins for individual publications), (III) month of publication, (IV) distribution of web-sources, (V) demographic-breakdown type distributions of citations, (VI) geographic-breakdown type distributions of citations, (VII) level-of-evidence (decided using SIGN-Criteria) (VIII) Q-categories of scientific journals, and (IX) h-index. Descriptive and correlational statistics were performed. Kruskal-Wallis test was used for AAS and dimensions-badge value comparisons while post-hoc analyses were performed by Dunn test. Spearman correlation coefficients were calculated to detect linear relationship between numerical variables. Analyses were performed by SPSS23.0 and p<0.05 was considered statistically significant. Results: Most (74%) of the disseminated articles were published in Q1-journals while evidence levels were mostly level-3/level-4. Content of the first 3 articles was about the impact of non-pharmaceutical interventions, origin of COVID-19 and chloroquine usage, respectively. There was no significant difference between AAS in different months (p=0.673) but dimensions-badges in January were significantly higher (p<0.05). There was a weak positive correlation between AAS and dimensionsbadge (r=0.250; p=0.017). Conclusion: Dimensions-badge and AAS results revealed that academia discussed COVID-19 much more in the first-month of pandemic, but then interests continued parallelly in academia and other social media platforms, including public. Academicians have discussed experiences of large-patient series but public preferred what is potentially protective or risky for them. Although enormously fast accumulation and dissemination of new scientific publications were witnessed, it seems sens-clinique rather than strict evidence-based-advice transferred to journals. Because infodemic is another emerging problem, every scientist should be ethically more responsible about the publication they choose to disseminate. Interpretations/public-messages of scientists might also be critical, given the fact that only 15% of discussed Covid-19 articles was in level-1/level-2 evidence © 2021,Turk Hijyen ve Deneysel Biyoloji Dergisi.All Rights Reserved

    ANKİLOZAN SPONDİLİTLİ HASTALARDA NÖROPATİK AĞRININ HASTALIK AKTİVİTE SKORLARI İLE İLİŞKİSİ VE ANTİ- TNF? KULLANIMININ ETKİSİ
    (2021) Kimyon, Gezmiş; Güneş, Ümran Gezici; Gümüşay, Meryem; Karadağ, Mehmet; Bay, Feyyaz; Melek, İsmet Murat
    AMAÇ: Bu çalışmada ankilozan spondiliti olan hastalarda nöropatik ağrının hastalık aktivite indekslerine etki edip etmediği ve aynı zamanda tedavide kullanılan anti-TNF? gibi ajanların bununla ilişkili olup olmadığını araştırmayı amaçladık. GEREÇ VE YÖNTEM: Çalışmaya modifiye New York kriterlerine göre ankilozan spondilit tanıs konan 98 hasta ve yaş ve cinsiyet uyumlu 99 sağlıklı kontrol alındı. Her iki grupta nöropatik ağrı painDETECT skorlamasına göre yapıldı. Ankilozan spondilit hastalarının hastalık aktiviteleri BASDAI (Bath Ankylosing Spondylitis Disease Activity Index), BASFI (Bath ankylosing spondylitis functional ındex), VAS ağrı (Visual Analog Scale) ve Leeds entezit indeksi ile değerlendirildi. Ayrıca herikigrubaHAQ(HealthAssesmentQuestionnaire)veBeckdepresyon ölçeği uygulandı. Ayrıca ankilozan spondilit hastaları anti-TNF? ilaç kullanan ve kullanmayan şeklinde iki grup olarak karşılaştırıldı. BULGULAR: PainDETECT hasta grubunda kontrol grubuna göre istatistiksel olarak anlamlı derecede yüksekti. Ankilozan spondilit grubunda ortalama painDETECT 22,10 kontrol grubunda ise 9,95 idi (p<0,001). Hasta grubunda VAS, HAQ ve Beck depresyon ölçeği kontrol grubuna göre istatistiksel olarak anlamlı derecede yüksek saptandı. Anlilozan spondilit hastaları anti-TNF? ilaç kullanan ve kullanmayan olarak incelendiğinde painDETECT ile anti-TNF? kullanmak arasında istatistiksel anlamlı bir fark saptanmadı. Anti- TNF? kullanan grupta painDETECET ortalama 20,30 kullanmayan grupta 17,80 (p=0,135) idi. Kolerasyon analizi yapıldığında ise painDETECT ile BASDAI, VAS ağrı ve Beck depresyon ölçeği arasında orta düzeyde pozitif yönde kolerasyon saptandı. SONUÇ: Ankilozan spondilitte nöropatik ağrı hastalık aktivite göstergeleri ile paralellik gösterir. Dolayısıyla nöropatik ağrı nedeniyle AS hastalık aktivitesinin yüksek saptanması, AS için verilecek aşırı tedavinin önüne geçebilir.Anti-TNF? ilaçlar ile nöropatik ağrı arasında herhangi bir ilişki saptamadık.

    Assessment of vitamin D levels in patients with sudden sensorineural hearing loss
    (2023) Sarı, Elif; Tokat, Taşkın; Aliyeva, Aynur; Karadağ, Mehmet; Eren, Fatma; Çatlı, Tolgahan; Olgun, Levent
    Aim: Vitamin D is important in antiproliferative, immunomodulatory, prodifferentiative effects, metabolic functions, and neuromuscular activity. We try to evaluate the relation between vitamin D deficiency and Idiopathic Sudden Sensorineural Hearing Loss (ISSHL) and its impact on response to treatment. Materials and Methods: This study was performed prospectively in 2 groups, 55 participants with SSHL and 55 with normal hearing without middle ear pathology. All patient information such as age, gender, lipid values, coagulation parameters, audiometry results, and vitamin D level was recorded at baseline. Patients with SSHL received steroid therapy at a decreasing dose of 1 mg/kg/day, and their response to treatment had evaluated according to posttreatment audiometry tests. Results: Vitamin D level in the SSHL group with a mean of 17.27±15.73 ng/ml was significantly less than the control group (31.31±27.21 ng/ml; p-value =0.001). The mean pure-tone audiometry (PTA) before treatment was 62.74±23.66 dB HL (range 28-117 dB) and 45.24±23.47 dB HL after treatment (range 6-101 dB HL). The patient group with less vitamin D values was statistically significant than the group with normal vitamin D values in terms of mean PTA before and after treatment (respectively: p=0.010; p=0.002). Pretreatment and posttreatment hearing levels were statistically higher in the group with normal vitamin D. Vitamin D values below 22.16 were a risk factor for sudden hearing loss (p=0.001). Conclusion: In our study, participials with SSHL found a higher vitamin D deficiency level. The role of pathophysiological mechanisms underlying SSHL remains uncertain; vitamin D affecting these mechanisms seems to be an important prognostic factor.

    (2021) Petekkaya, Emine; Karadağ, Mehmet; Dokur, Mehmet
    Objectives: This study aimed to investigate the significance of publications examining the effectiveness of education methods in the field of anatomy with the method of bibliometric and altmetric analysis, as well as online attention levels. Methods: To search all publications, “Anatomy education” was entered as a search term on the Web of Science database. The topics, journal impact factors, publication years and research centers of the first 100 articles with the highest numbers of citations were examined, and their analysis was conducted with the “Altmetric it on website: http: almetric.com”. Results: Four thousand, three hundred fifty-six articles published in the period of 1975-2019 containing the key phrase “Anatomy education” were found on Web of Science. The study with the highest number of citations was the study published by McLachlan et al. titled “Teaching anatomy without cadavers, 2004”. It was observed that the study titled “The production of anatomical teaching resources using three-dimensional (3D) printing technology, 2014” was the article with the highest rate of sharing on Twitter with the highest altmetric attention score (AAS) value. The AAS rates varied between 130 and 0. Conclusions: Bibliometric and altmetric analysis provides significant but different points of view regarding the effects of an article in the world of science. The altmetrics score may provide contributions in determining the direction of studies regarding the high-level interests and perceptions of the public on dynamic science and the field of medicine.

    Comparison of GAM and DLNM Methods for Disease Modeling in Environmental Epidemiology
    (2021) Karadağ, Mehmet; Kul, Seval; Yoloğlu, Saim; Boğan, Mustafa; Al, Behçet
    ABSTRACT Objective: In this study, it was aimed to compare the performance results of the methods modeled by using generalized additive models (GAM) and distributed lag non-linear models (DLNM) methods from real data of three different outcome variables of three separate diseases related to air pollution. Material and Methods: The data were retrospectively obtained from three hospitals under the General Secretariat of Gaziantep province public hospitals for a total of 1,916 days between 01 January 2009 and 31 March 2014. Response variables were number of the emergency unit admission, hospitalization and mortality due to asthma, chronic obstructive pulmonary disease (COPD) and pneumonia. The response variables were estimated by GAM and DLNM methods by building four different models and the performances of the models were compared. Results: When the estimation performances of GAM and DLNM methods are compared for each of the dependent variables in the prediction of hospitalizations due to asthma, GAM model IV [Akaike Information Criteria (AIC) (4,280.63)] values were found to perform the best. It was observed that DLNM method performed better than GAM in models established for the prediction of almost all other dependent variables. For when compare the odds ratio (OR) plot estimated on particulate matter (PM10); it was seen that GAM method made predictions with lower standard error compared to DLNM methods. Conclusion: When the models created with each dependent variable were compared; it was generally observed that superior performance was obtained from the DLNM method. However, the lowest standard error in the OR charts were observed in the models using the GAM method.

    Could Systemic Inflammation-Based Prognostic ScoresPredict the Clinical Outcome in Patients with Breast CancerTreated with Everolimus Plus Exemestane?
    (2021) Çelik, Emir; Samancı, Nilay Sengul; Karadağ, Mehmet; Demirci, Nebi Serkan; Demirelli, Fuat Hulusi
    Objectives: No study to clarify which inflammation score could best reflect survival in a cohort of metastatic breastcancer (mBC) patients who received everolimus plus exemestane. Methods: The impact of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and prognostic nutritional index (PNI) on PFS and OS was evaluated. Results: A total of 80 mBC patients were included. Median PFS was 8.9 months and median overall survival (OS) was31.8 months. We found that there was no significant difference between NLR, PLR, SII, and PNI groups for median PFSand OS. Conclusion: Inflammation-based prognostic scores were not correlated with prognosis in patients with mBC who hadbeen treated with everolimus plus exemestane.

    Hospitalize Kanser Hastalarında Malnütrisyon Riski ve Yaşam Kalitesine Etkisi
    (2021) Çelik, Emir; Aslan, Muhammed Şamil; Samancı, Nilay Şengül; Karadağ, Mehmet; Suzan, Veysel; Çelik, Yasemin Çakan; Demirci, Nebi Serkan
    Amaç: Malnutrisyon kanser hastalarında en sık klinik sorunlardan biridir. Hospitalize kanser hastalarında sıklığı daha da artar. Bu çalışmada hospitalize edilmiş kanser hastalarında malnutrisyon sıklığı ve yaşam kalitesine (YK) etkisinin araştırılması amaçlandı.Gereç ve Yöntem: Kesitsel olarak dizayn edilen bu çalışmada medikal onkoloji servisine yatan kanser tanılı hastalar için Nutrisyon Risk Skorlaması-2002 (NRS-2002) ve “Avrupa Kanser Araştırma ve Tedavi Teşkilatı” (EORTC)-QLQ C30 ölçekleri dolduruldu. Klinik ve laboratuvar paramatreleri ile malnutrisyon riski ve YK arasındaki ilişki istatistik yöntemleri ile analiz edildi.Bulgular: Çalışmaya 113 hasta dahil edildi. NRS-2002 sonuçlarına göre %42,5 (n=48) hastada malnutrisyon riski tespit edildi. Cinsiyet ve yaş açısından gruplar arasında fark yoktu. EORTC-QLQ C30 ölçek puanları karşılaştırıldığında malnutrisyon riskinin genel sağlık skoru üzerine etkisi yoktu (p=0,679). Fiziksel fonksiyon ve rol fonksiyon skorları malnutrisyon riski olanlarda anlamlı olarak daha düşüktü (daha kötü YK). Diğer fonksiyonel skalalar açısından gruplar arasında anlamlı istatistiksel fark yoktu. Daha iyi genel sağlık skoruna etki eden faktörlere tek değişkenli lojistik regresyon (LR) uygulandığında sadece hemoglobin düzeyi anlamlı faktör olarak bulundu. Bu yüzden çok değişkenli LR yapılmadı.Sonuç: Malnutrisyon risk değerlendirmesi hastaneye yatan her kanser hastasına mutlaka yapılmalıdır. Malnutrisyon riski olan hastalarda EORTC-QLQ C30 ölçeğine göre daha kötü YK olduğu görüldü. Risk saptanan hastalara erken dönemde nutrisyon desteği verilmelidir.

    The Relationship between Platelet İndices and Radiological İnvolvement in Pulmonary Thromboembolism
    (2023) Akgün, Kadir Burak; Korkmaz, İnan; Karadağ, Mehmet
    Objective: Pulmonary thromboembolism (PTE) is a disease characterized by occlu- sion of the pulmonary artery and its branches by thrombus material as a result of stasis, hypercoagulability, and/or endothelial damage. Recent studies have focused on platelet (PLT) parameters, mortality of the disease, and its use as a diagnostic parameter. In particular, a significant relationship was found between high mean PLT volume (MPV) values and mortality and disease risk in the meta-analyses. The aim of our study is to examine the relationship between PLT parameters and the severity of radiological involvement. Material and Methods: The files of patients who were followed up with the diag- nosis of pulmonary thromboembolism between 2012 and 2021 were reviewed ret- rospectively. The patients were radiologically divided into 3 groups: (1) those with major branch involvement, (2) those with segmental branch involvement without ma- jor branch involvement, and (3) those with only subsegmental branch involvement. In addition, patients were examined in two separate groups according to whether there was more than 50% of involvement in the main branch radiologically and whether the right ventricle/left ventricle ratio was above 0.9 or not, radiologically. PLT, neutrophil, lymphocyte, platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio, MPV, plateletcrit (PCT), platelet distribution width (PDW), and PLT large cell ratio data in complete blood count measurements taken from patients at the time of diagnosis were also recorded. Results: There was a significant correlation between rising in PLR and occlusion in the major branch more than 50% (p=0.041). PLT, PDW, PCT, and neutrophil values differed radiologically according to the involvement of major, segment, and subseg- ment; however, subgroup analyses did not provide the linear difference that we ex- pected in our study.Conclusion: An increase in the PLR appears to be associated with radiological weight in pulmonary thromboembolism. We think that the relationship between PLT indices and radiological involvement should be supported by multicenter studies.

    The relationship between preoperative hemoglobin, albumin, lymphocyte, and platelet (HALP) score and right colon cancer surgery outcomes: a retrospective cohort study
    (2024) Ay, Oğuzhan Fatih; Erol, Mehmet Fatih; Arıcı, Sinan; Karadağ, Mehmet
    Objectives: This study aims to investigate the association between the preoperative Hemoglobin Albumin Lymphocyte Platelet (HALP) score and surgical outcomes in right colon cancer patients. Methods: This retrospective cohort study included patients undergoing elective right colon adenocarcinoma surgery from January 2017 to June 2023 at Bursa Yuksek Ihtisas Training and Research Hospital. The HALP score, calculated from hemoglobin, albumin, lymphocyte, and platelet levels, aimed to predict perioperative morbidity through receiver operating characteristic (ROC) curve analysis. Results: The study involved 67 patients, mostly male with an average age of 68.28 years, undergoing 46 open and 21 laparoscopic surgeries. Although the HALP score's cutoff value was established, it did not significantly predict perioperative morbidity (P>0.05). However, lower platelet counts (<318×103/L) and open surgery type correlated significantly with higher morbidity (P<0.05). Conclusions: This study reveals that the HALP score may not effectively predict perioperative morbidity in right colon cancer surgeries, highlighting platelet counts as a more promising marker. Our findings also confirm the increased morbidity associated with open surgeries, challenging existing assumptions and guiding clinical practice.

    A social attention with altmetric score analysis on the relationship between oxidative stress and cancer
    (2022) Hanikoğlu, Ferhat; Vardar, Gökay; Ozben, Tomrıs; Karadağ, Mehmet; Dokur, Mehmet
    Oxidative stress has a crucial role in the development of various cancers. The aim of our study was to identify and analyze research articles about oxidative stress and cancer that have attracted the highest online attention. Our study is the first one evaluating social media attention to the articles on cancer and oxidative stress published in academic literature. Altmetric Explorer was used to identify research articles about oxidative stress and cancer. We evaluated the top 50 research articles having the highest Altmetric attention scores (AAS), using the Altmetric.com database. The Altmetric Attention Score (AAS) of 50 articles (T50) investigated was between 15 and 445 (mean±SD; 60.66±86.18). The social media platforms where the T50 articles are mentioned from highest to the lowest scores are the Facebook (n=2678) followed by Twitter (n=886) and Google + users (n=214). According to demographic breakdowns in Twitter, tweet counts were similar between scientists (34%) and not scientists (32%). Total citations of the 50 articles ranged from 3 to 3700 (mean ± SE; 203.40±87.07). A weak statistically significant positive correlation was found between the Altmetric score and the Q category (r=0.338: p=0.016). Interestingly, there was no correlation between Altmetric score and number of article citations. The increasing use of online social media platforms makes this area worthy, and the online impact of an article is becoming progressively more convenient for academic and public accessibility. Social media also may give oppurtunity to the researchers for disseminating their studies in scholar and non-scholar platforms.

    The Validity and Reliability of the Turkish Version of Short Questionnaire to Assess Healthcare Professionals’ Perceptions of Asynchronous Telemedicine Services
    (Mattioli 1885, 2022) Karadağ, Mehmet; Hüzmeli, İrem; Hüzmeli, Esra Doğru
    Study Objectives: The purpose of this study was to translate the “Short Questionnaire to Assess Healthcare Professionals’ Perceptions of Asynchronous Telemedicine Services” into Turkish, and analyze it for validity and reliability. Methods: A total of 80 individuals were accepted in this cross-sectional descriptive study. The original scale was translated into Turkish (forward translate, reconciliation, back translation, review, plot test, final scale). Cronbach alpha, exploratory and confirmatory factor analysis were employed to assess the reliability and validity of the measurement model. Results: Cronbach’s alpha was obtained as 0.880 in the Quality and 0.829 in the Difficulties subscales. The overall alpha value was 0.885. ICC (95% CI) values of the scale were calculated as 0.841 (0.775 to 0.891). RMSEA=0.09 was observed below the acceptable level of 0.10; GFI=0.92, AGFI=0.81 above the acceptable threshold of 0.90. Conclusion: The Turkish version of the scale is valid and reliable, and can be used in studies evaluating healthcare professionals’ perceptions of asynchronous telemedicine services. © Mattioli 1885
