    (W.B. Saunders Ltd, 2021) Kokturk N.; Babayigit C.; Kul S.; Duru Cetinkaya P.; Atis Nayci S.; Argun Baris S.; Karcioglu O.; Aysert P.; Irmak I.; Akbas Yuksel A.; Sekibag Y.; Baydar Toprak O.; Azak E.; Mulamahmutoglu S.; Cuhadaroglu C.; Demirel A.; Kerget B.; Baran Ketencioglu B.; Ozger H.S.; Ozkan G.; Ture Z.; Ergan B.; Avkan Oguz V.; Kilinc O.; Ercelik M.; Ulukavak Ciftci T.; Alici O.; Nurlu Temel E.; Ataoglu O.; Aydin A.; Cetiner Bahcetepe D.; Gullu Y.T.; Fakili F.; Deveci F.; Kose N.; Tor M.M.; Gunluoglu G.; Altin S.; Turgut T.; Tuna T.; Ozturk O.; Dikensoy O.; Yildiz Gulhan P.; Basyigit I.; Boyaci H.; Oguzulgen I.K.; Borekci S.; Gemicioglu B.; Bayraktar F.; Elbek O.; Hanta I.; Kuzu Okur H.; Sagcan G.; Uzun O.; Akgun M.; Altinisik G.; Dursun B.; Cakir Edis E.; Gulhan E.; Oner Eyuboglu F.; Gultekin O.; Havlucu Y.; Ozkan M.; Sakar Coskun A.; Sayiner A.; Kalyoncu A.F.; Itil O.; Bayram H.
    The COVID-19-related death rate varies between countries and is affected by various risk factors. This multicenter registry study was designed to evaluate the mortality rate and the related risk factors in Turkey. We retrospectively evaluated 1500 adults with COVID-19 from 26 centers who were hospitalized between March 11 and July 31, 2020. In the study group, 1041 and 459 cases were diagnosed as definite and highly probable cases, respectively. There were 993 PCR-positive cases (66.2%). Among all cases, 1144 (76.3%) were diagnosed with non-severe pneumonia, whereas 212 (14.1%) had severe pneumonia. Death occurred in 67 patients, corresponding to a mortality rate of 4.5% (95% CI:3.5–5.6). The univariate analysis demonstrated that various factors, including male sex, age ≥65 years and the presence of dyspnea or confusion, malignity, chronic obstructive lung disease, interstitial lung disease, immunosuppressive conditions, severe pneumonia, multiorgan dysfunction, and sepsis, were positively associated with mortality. Favipiravir, hydroxychloroquine and azithromycin were not associated with survival. Following multivariate analysis, male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were found to be independent risk factors for mortality. Among the biomarkers, procalcitonin levels on the 3rd-5th days of admission showed the strongest associations with mortality (OR: 6.18; 1.6–23.93). This study demonstrated that the mortality rate in hospitalized patients in the early phase of the COVID-19 pandemic was a serious threat and that those patients with male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were at increased risk of mortality; therefore, such patients should be closely monitored. © 2021 Elsevier Ltd

    (Frontiers Media S.A., 2022) Babayigit C.; Kokturk N.; Kul S.; Cetinkaya P.D.; Atis Nayci S.; Argun Baris S.; Karcioglu O.; Aysert P.; Irmak I.; Akbas Yuksel A.; Sekibag Y.; Baydar Toprak O.; Azak E.; Mulamahmutoglu S.; Cuhadaroglu C.; Demirel A.; Kerget B.; Baran Ketencioglu B.; Ozger H.S.; Ozkan G.; Ture Z.; Ergan B.; Avkan Oguz V.; Kilinc O.; Ercelik M.; Ulukavak Ciftci T.; Alici O.; Nurlu Temel E.; Ataoglu O.; Aydin A.; Cetiner Bahcetepe D.; Gullu Y.T.; Fakili F.; Deveci F.; Kose N.; Tor M.M.; Gunluoglu G.; Altin S.; Turgut T.; Tuna T.; Ozturk O.; Dikensoy O.; Yildiz Gulhan P.; Basyigit I.; Boyaci H.; Oguzulgen I.K.; Borekci S.; Gemicioglu B.; Bayraktar F.; Elbek O.; Hanta I.; Kuzu Okur H.; Sagcan G.; Uzun O.; Akgun M.; Altinisik G.; Dursun B.; Cakir Edis E.; Gulhan E.; Oner Eyuboglu F.; Gultekin O.; Havlucu Y.; Ozkan M.; Sakar Coskun A.; Sayiner A.; Kalyoncu A.F.; Itil O.; Bayram H.
    Background and objectives: Although several repurposed antiviral drugs have been used for the treatment of COVID-19, only a few such as remdesivir and molnupiravir have shown promising effects. The objectives of our study were to investigate the association of repurposed antiviral drugs with COVID-19 morbidity. Methods: Patients admitted to 26 different hospitals located in 16 different provinces between March 11–July 18, 2020, were enrolled. Case definition was based on WHO criteria. Patients were managed according to the guidelines by Scientific Board of Ministry of Health of Turkey. Primary outcomes were length of hospitalization, intensive care unit (ICU) requirement, and intubation. Results: We retrospectively evaluated 1,472 COVID-19 adult patients; 57.1% were men (mean age = 51.9 ± 17.7years). A total of 210 (14.3%) had severe pneumonia, 115 (7.8%) were admitted to ICUs, and 69 (4.7%) were intubated during hospitalization. The median (interquartile range) of duration of hospitalization, including ICU admission, was 7 (5–12) days. Favipiravir (n = 328), lopinavir/ritonavir (n = 55), and oseltamivir (n = 761) were administered as antiviral agents, and hydroxychloroquine (HCQ, n = 1,382) and azithromycin (n = 738) were used for their immunomodulatory activity. Lopinavir/ritonavir (β [95% CI]: 4.71 [2.31–7.11]; p = 0.001), favipiravir (β [95% CI]: 3.55 [2.56–4.55]; p = 0.001) and HCQ (β [95% CI]: 0.84 [0.02–1.67]; p = 0.046) were associated with increased risk of lengthy hospital stays. Furthermore, favipiravir was associated with increased risks of ICU admission (OR [95% CI]: 3.02 [1.70–5.35]; p = 0.001) and invasive mechanical ventilation requirement (OR [95% CI]: 2.94 [1.28–6.75]; p = 0.011). Conclusion: Our findings demonstrated that antiviral drugs including lopinavir, ritonavir, and favipiravir were associated with negative clinical outcomes such as increased risks for lengthy hospital stay, ICU admission, and invasive mechanical ventilation requirement. Therefore, repurposing such agents without proven clinical evidence might not be the best approach for COVID-19 treatment.

    Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study
    (Galenos Publishing House, 2023) Oktay A.; Aslan Ö.; Taşkın F.; Tunçbilek N.; İçten S.G.E.; Balcı P.; Arıbal M.E.; Çelik L.; Örgüç İ.Ş.; Demirkazık F.B.; Gültekin S.; Aydın A.M.; Durmaz E.; Kul S.; Binokay F.; Çetin M.; Emlik G.D.; Akpınar M.G.; Voyvoda S.N.K.; Polat A.V.; Akın I.B.; Yıldız Ş.; Poyraz N.; Özsoy A.; Öztekin P.S.; Elverici E.; Bayrak İ.K.; İkizceli T.; Dinç F.; Sezgin G.; Gülşen G.; Tunçbilek I.; Yalçın S.R.; Çolakoğlu G.; Ağlamış S.; Yılmaz R.; Rona G.; Durhan G.; Güner D.C.; Yabul F.Ç.; Karabekmez L.G.; Tutar B.; Göktaş M.; Buğdaycı O.; Suner A.; Özdemir N.
    Purpose: The clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions. Methods: This retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson's chi-squared test, the Fisher-Freeman-Halton test, and Fisher's exact test were used for the statistical analyses. Results: The overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes. Conclusion: ADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision. © 2023, Galenos Publishing House. All rights reserved.
