Background: Urinalysis has an important place in evaluating kidney and urinary tract infections. Automated urine analyzers enhance productivity and turnover in laboratories and economize time and labor required for analysis. In the present study, we evaluated and compared analytic and diagnostic performance of UriSed2 with LX-8000R, which is a novel image-based automated urine sediment analyzer. Methods: A total of 178 urine samples sent to our laboratory were evaluated by the two urine analyzers and standard manual microscopy. Precision and comparison studies were done in accordance with CLSI guidelines. Results: Sensitivity assessment revealed similar outcomes with both UriSed2 and LX-8000R devices for erythrocyte count (RBC), whereas UriSed2 device yielded higher outcomes for leukocyte count (WBC) and epithelial cells (EPI) than LX-8000R analyzer. Specificity of UriSed2 for WBC and RBC was higher than that of LX-8000R device. According to Gamma statistics, both urine analyzers showed perfect consistency for WBC, RBC and EPI cell counts. Manuel microscopy revealed statistically significant correlation between LX-8000R and UriSed2 in terms of WBC and RBC. Manual evaluation by Bland-Altman analysis demonstrated lower WBC and RBC values and higher EPI as compared to both UriSed2 and LX-8000R devices. As the result of Passing-Bablok regression analysis, both devices were found to be inconsistent with manual microscopy. Conclusion: We think that evaluation of automated urine analyzers will be more meaningful when they are evaluated together with urine samples and patient clinic in addition to comparing with manual microscopy.
Bölgemizde yaş, ırk, deri rengi, iklim, enlem özellikleri açısından aynı olan FMS, MAS, FM+MAS'lı hastalarda D vitamini düzeyini araştırmak ve hastalık parametreleri ile ilişkisini tespit ederek; Özellikle FMS ve MAS' birlikteliğinde oluşabilecek farkı ortaya koymaktı.Yöntemler: Dicle Üniversitesi Tıp Fakültesi Fiziksel Tıp ve Rehabilitasyon Anabilim Dalı polikliniğine başvuran ACR 1990 FMS tanı kriterlerine uyan 23 FMS'li, 36 MAS'lı ve her iki tanıyı birden taşıyan 21 hasta ile 39 sağlıklı semptomsuz bireyden kan örnekleri alınarak laboratuvarda analiz edildi.Bulgular: FMS ve FMS+MAS hastalarında normal popülasyonla kıyaslandığında D vitamini düşük bulundu. FMS ve FMS+MAS'ta normal kabul ettiğimiz sınırın altında vitamin D seviyesi tespit edilmesine rağmen sadece FMS'deki düşüklük istatiksel olarak anlamlı bulundu (p< 0,05). D vitamin düzeylerini ortalama olarak FMS'li grupta 16,5 ng/ml, MAS'lı grupta 25,5 ng/ml, FMS+MAS'lı grupta ise 20,6 ng/ml kontrol grubunda 26,5 ng/ml seviyelerinde tespit edildi. D vitamin eksikliğinin FMS, MAS, FMS+MAS'lı hastalarda ağrı, uyku bozukluğu, yorgunluk, depresyon, anksiyete üzerine etkilerinin olduğu tespit edilmiştir.Sonuç: Sonuç olarak FMS ve MAS hastalarında sağlıklı kontrollere göre D vitamini düzeyi düşük bulundu. Bu nedenle ağrı, yorgunluk gibi şikâyetlerle polikliniklere başvuran hastalarda vitamin D düzeyi düşüklüğünün olabileceği düşünülüp araştırılmalıdır.
Background: Studies on biomarkers in the diagnosis of myocardial infarction are ongoing. Adropin is a biomarker that has been studied and has been shown to have different effects. This study aimed to examine the adropin level of patients with myocardial infarction within the first 24 hours, as well as its relationship with cobalamin and folic acid.Material and methods: The control group included 70 patients whose troponin values did not increase and no coronary lesions were detected. In the ST-elevation myocardial infarction (STEMI) group, 70 patients with ST elevation on ECG and coronary total thrombosis on coronary angiography were evaluated. Coronary lesion severity was measured using the SYNergy between percutaneous coronary intervention (PCI) with TAXUS and Cardiac Surgery (SYNTAX) score tool. Hemogram, troponin, adropin, c-reactive protein (CRP), cobalamin, folic acid, and other biochemical parameters were evaluated in all patients.Results: In the STEMI group, a significant increase was observed in the adropin level along with the troponin and CRP levels in the first 24 hours (p<0.001). Cobalamin and folic acid levels were low in the same group (p:0.016, p<0.001). While a strong negative correlation was observed between adropin and cobalamin, no correlation was found with other parameters. Conclusion:The study supports that adropin could be used as a cardiac biomarker in the early stages of STEMI patients. Another result is with low cobalamin and folic acid levels in patients with myocardial infarction which needs to be further explained with the strong negative correlation between adropin and cobalamin.
Background: Dried blood spot samples are suitable for diagnosing some congenital errors of metabolism; however, they provide limited benefit in the regular monitoring of amino acids. Objectives: The present study aimed to evaluate Alanine (Ala), Arginine (Arg), Citrulline (Cit), Glutamic Acid (Glu), Glycine (Gly), Isoleucine (Ileu), Leucine (Leu), Methionine (Met), Ornithine (Orn), Phenylalanine (Phe), Tyrosine (Tyr), and Valine (Val) amino acid concentrations in dried blood and plasma samples obtained simultaneously. Methods: Amino acid concentrations were determined in the plasma, and dried blood spot samples obtained simultaneously from 145 patients (50 females and 95 males). Amino acid concentrations in the plasma and dried blood spot samples were studied by LC-MS/MS using original kits. Results: There were significant differences between dried blood spots and plasma in all amino acid concentrations, except for Met and Val. Bland-Altman analysis revealed the highest mean differences in Glu (-148.1), Gly (-70.1), and Ala (-58.1). Deming regression analysis showed that plasma and dried blood spot samples were consistent concerning Cit, Met, Phe, and Tyr concentrations. Conclusions: Differences in methodology and sample can influence amino acid concentrations. Dried blood spot samples might cause errors in amino acid screening programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
