Orta Karadeniz’den Örneklenen Merlangius merlangus‘un Dört Otolit Karakterinin Dalgalı Asimetrisinin İncelenmesi

Fluctuating asymmetry was calculated for the otolith width, length, area and perimeter of Merlangius merlangus caught in the Middle Black Sea. In the present study, M. merlangus samples were divided nine-total length groups. All total length groups were examined for asymmetry values in the otolith characters, the highest asymmetry values were found in the Group III. The lowest asymmetry values in four otolith characters such as area, length, perimeter, and width were calculated in the Group I and Group IX. In this study, it was determined that the otolith asymmetry levels of M. merlangus in the Middle Black Sea were varied between the four otolith characters, the otolith area has the highest and the otolith length has the lowest asymmetric feature. In addition, there was no significant relationship between the asymmetry values of the four otolith characters and total length. The asymmetry in these otolith characters may be a result of the stress from different pollutants in the Black Sea.Orta Karadeniz'den yakalanan Merlangius merlangus’un otolit genişliği, uzunluğu, alanı ve çevresi için dalgalı asimetri değerleri hesaplanmıştır. Bu çalışmada elde edilen M. merlangus örnekleri dokuz total boy grubuna ayrılmıştır. Tüm total boy grupları, otolit karakterlerindeki asimetri değerleri açısından incelenmiş ve en yüksek asimetri değerleri Grup III'de bulunmuştur. Alan, uzunluk, çevre ve genişlik gibi dört otolit karakterindeki en düşük asimetri değerleri Grup I ve Grup IX'de hesaplanmıştır. Bu çalışmada, Orta Karadeniz'deki M. merlangus'un otolit asimetri düzeylerinin bu dört otolit karakteri arasında farklılık gösterdiği, otolit alanının en yüksek ve otolit boyunun ise en düşük asimetrik özelliğe sahip oluğu belirlenmiştir. Ayrıca bu dört otolit karakterinin asimetri değerleri ile total boy grupları arasında anlamlı bir ilişki yoktur. Bu türün otolit karakterlerinde gözlenen asimetri Karadeniz’deki farklı kirleticilerden kaynaklı stresin bir sonucu olabilir

Prevalence and Factors Affecting Postoperative Delirium in a Neurosurgical Intensive Care Unit

PURPOSE: The aim of this study was to identify the prevalence of, and factors affecting, postoperative delirium (POD) in patients in the neurosurgical intensive care unit. METHODS: A cross-sectional study of 127 Turkish neurosurgical intensive care unit patients admitted between May 2018 and May 2019 was conducted. Patients were assessed for the development of POD using the Intensive Care Delirium Screening Checklist. We collected other independent data variables daily. Data were analyzed using independent sample t test, chi(2) test, and logistic regression. RESULTS: The prevalence rates of POD on the first and second postoperative days were 18.9% and 8.7%, respectively. Logistic regression analysis showed that the Glasgow Coma Scale score, albumin level, Spo(2) level, hemoglobin values, undergoing cranial surgery, and having intra-arterial catheter were the independent risk factors for POD. CONCLUSION: These findings may contribute to identifying patients at risk for developing POD and developing strategies to improve patient outcomes
