On Linear Codes Over a Non-Chain Ring
In this paper, we study skew cyclic and quasi cyclic codes over the ring S = F2 +uF2 + vF2 where u2 = u, v2 = v, uv = vu = 0.We investigate the structural properties of them. Using a Gray map on S we obtain the MacWilliams identities for codes over S. The relationships between Symmetrized, Lee and Hamming weight enumerator are determined

The efficacy of cinacalcet in the treatment of hyperparathyroidism in Turkish hemodialysis patient population
WOS: 000393291900012OBJECTIVE: Cinacalcet reduces parathyroid hormone levels by increasing the sensitivity of the parathyroid gland to calcium. in this study, we firstly aimed to evaluate the efficacy of cinacalcet in Turkish hemodialysis patients. MATERIAL and METHODS: 4483 hemodialysis patients were screened and 469 patients who had used cinacalcet were included in the study. the patients were divided into 4 groups according to drug usage durations (Group 1: 3 months, Group 2: 6 months, Group 3: 9 months and Group 4: 12 months). the patients' Parathormone, Ca, P and CaxP levels at the 3rd, 6th, 9th and 12th months were compared to the start of treatment and previous months. RESULTS: the levels of Parathormone, Ca, P and CaxP significantly decreased compared to their initial levels in all groups (from 1412 pg/ml to 1222 pg/mL for Parathormone, p< 0,001) in the 3rd month. However, this reduction was not continued in the subsequent months (Parathormone: 1381 pg/ml for the 12th month). CONCLUSION: Cinacalcet may not provide adequate benefit in control of hyperparathyroidism in Turkish hemodialysis patient population
Outcome of COVID-19 in Patients With Autoimmune Hepatitis: An International Multicenter Study
Background and Aims: Data regarding outcome of COVID-19 in patients with autoimmune hepatitis (AIH) are lacking. Approach and Results: We performed a retrospective study on patients with AIH and COVID-19 from 34 centers in Europe and the Americas. We analyzed factors associated with severe COVID-19 outcomes, defined as the need for mechanical ventilation, intensive care admission, and/or death. The outcomes of patients with AIH were compared to a propensity score?matched cohort of patients without AIH but with chronic liver diseases (CLD) and COVID-19. The frequency and clinical significance of new-onset liver injury (alanine aminotransferase > 2 × the upper limit of normal) during COVID-19 was also evaluated. We included 110 patients with AIH (80% female) with a median age of 49 (range, 18-85) years at COVID-19 diagnosis. New-onset liver injury was observed in 37.1% (33/89) of the patients. Use of antivirals was associated with liver injury (P = 0.041; OR, 3.36; 95% CI, 1.05-10.78), while continued immunosuppression during COVID-19 was associated with a lower rate of liver injury (P = 0.009; OR, 0.26; 95% CI, 0.09-0.71). The rates of severe COVID-19 (15.5% versus 20.2%, P = 0.231) and all-cause mortality (10% versus 11.5%, P = 0.852) were not different between AIH and non-AIH CLD. Cirrhosis was an independent predictor of severe COVID-19 in patients with AIH (P < 0.001; OR, 17.46; 95% CI, 4.22-72.13). Continuation of immunosuppression or presence of liver injury during COVID-19 was not associated with severe COVID-19. Conclusions: This international, multicenter study reveals that patients with AIH were not at risk for worse outcomes with COVID-19 than other causes of CLD. Cirrhosis was the strongest predictor for severe COVID-19 in patients with AIH. Maintenance of immunosuppression during COVID-19 was not associated with increased risk for severe COVID-19 but did lower the risk for new-onset liver injury during COVID-19.Fil: Efe, Cumali.

Effects of immunosuppressive drugs on COVID-19 severity in patients with autoimmune hepatitis
Background: We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). Patients and methods: Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. Results: We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. Conclusion: Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.Fil: Efe, Cumali.

The examination of the effect of virtual patient visits on stress response in post-coronary artery bypass graft surgery
Sanal hasta ziyaretinin stres yanıta etkisi bilinmemektedir. Bu çalışma ile sanal ziyaretin koroner arter baypas greft cerrahisi sonrası serum kortizol seviyesi ve durumluk kaygı puanına etkisinin belirlenmesi amaçlandı. Araştırma 1 Aralık 2022-1 Mart 2023 tarihleri arasında bir Eğitim ve Araştırma Hastanesi'nin Kalp Damar Cerrahisi YBÜ'de yapılan önce-sonra kontrollü klinik bir çalışmadır. Araştırmaya başlamadan önce etik onay alındı (Onay no: 2022/221). Koroner arter baypas greft cerrahisi sonrasında en az 12 saatini doldurmuş hastalar, 20-30 dakika aile üyeleri ile görüntülü görüşme programı (zoom) ile görüştürüldüler. Hastalar sanal ziyaretten bir saat önce (T0) ve sanal ziyaretten bir saat sonra (T1) değerlendirildiler. Serum kortizol; Enzim Linked İmminosolbent Assay (ELISA) yöntemi ile kaygı ve ağrı seviyesinin belirlenmesinde görsel kıyaslama ölçeği kullanıldı. İstatistiksel anlamlılık için p0.05). T0 ölçümünde durumluk kaygı seviyesi puan ortalaması 3.75±3.31 T1 ölçümünde durumluk kaygı puan ortalaması 2.30±2.66 olarak ölçüldü. Karşılaştırıldığında ise aradaki farkın istatistiksel olarak anlamlı olduğu belirlendi (p=0.002) (p0.05). However, the state anxiety level scores were significantly different between T0 (3.75±3.31) and T1 (2.30±2.66) measurements (p=0.002) (p<0.05). There was a moderate positive correlation between serum cortisol levels and state anxiety scores at both T0 (p=0.001) and T1 (p=0.005) measurements. Comparing T0 and T1 measurements, it was found that 72% of the patients had a decrease in serum cortisol levels, while 23% experienced an increase. Additionally, 62% of the patients showed a decrease in anxiety levels, whereas 28% had an increase. In conclusion, virtual patient visits have a positive effect on stress levels in a significant portion of patients. Further large-scale studies should be conducted in different patient groups, and qualitative research should be carried out to explore the effects of virtual visits on patients
Bir tasarım stratejisi olarak yapı dokusu oluşturma yaklaşımının evrensel olarak tasarlanmış çevrelerin yaratılmasındaki potansiyelinin araştırılması
The goal of this study is to reread the strategies of formal organization in architecture, which are called أmat-buildingؤ and أmat-urbanismؤ, exploring their potential to contribute to the creation of universally designed built environments in the 21st century. The idea of mat-building was first delineated by Alison Smithson in 1974, in her article أHow to Recognize and Read Mat-Building,ؤ by means of its traditional and modern examples. The concept of universal design was first used in 1970̕s and reinterpreted by the American architect Ronald Mace in 1985. Since then, it has become a widely accepted design approach that is also known as ءinclusive design̕ and ءdesign for all̕. Mat-building can be considered as a viable design approach that can respond to the crucial need for equally accessible, adjustable and adaptable built environments for all people all over the world. The study aims not only to evaluate the exemplary mat like configurations in light of the universal design principles. It also tries to point to the new ways for developing creative ideas and design theories, and emphasizes the significance of implementing the universal design approach in contemporary architecture and urbanism.M.Arch. - Master of Architectur
