The most effective treatment modality was P-CS according to ultrasonographic and other findings. Although there were inverse correlations between the CSA of MN and sensory and motor MN conduction velocity, no relationship was found between symptom severity, functional status and US findings or electrophysiological studies.
Adding the scores obtained from SI and ABG to the sECG enhances the specificity of sECG in predicting RVD (+) or severe PE patients, although a lesser degree decreasing in sensitivity may occur.
It has been suggested that reactive oxygen species (ROS) plays an important role in radio contrast media (RCM)-induced ischemia reperfusion tissue injury although antioxidants may have protective effects on the injury. We investigated the effects of erdosteine as an antioxidant agent on RCM-induced liver toxicity in rats by evaluation of lipid peroxidation (as TBARS), catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH) and glutathione peroxidase (GSH-Px) values and histological evaluation. Twenty-one rats were equally divided into three groups as follows: control, RCM, and RCM plus erdosteine. RCM was intraperitoneally administered for 1 day. Erdosteine was administered orally for 2 days after RCM administration. Liver samples were taken from the rats and they homogenized in a motor-driven tissue homogenizer. TBARS levels were significantly (p < 0.005) higher in RCM group than in control although SOD activities significantly (p < 0.05) decreased in RCM group. TBARS levels were lower in RCM plus erdosteine group than in control although SOD activity and GSH level increased (p < 0.05) in liver as compared to RCM alone. Erdosteine showed also histopathological protection (p < 0.0001) against RCM induced hepatotoxicity. GSH-Px and CAT activities were not statistically changed by the erdosteine. According to our results, it can be concluded that radiocontrast media can induce oxidative stress in liver as suggested by previous studies. Erdosteine seems to be protective agent on the radiocontrast media-induced liver toxicity by inhibiting the production of ROS via the enzymatic antioxidant system.
Aim
In this study it was aimed to evaluate the prognostic factors for the geriatric patients with confirmed COVID-19 in a tertiary-care hospital at Kastamonu region of Turkey.
Method
Patients (≥65-year-old) who had PCR positivity for COVID-19 between March 2020 and April 2020 in our center were recorded retrospectively. A p value less than 0.05 was considered significant. Ethical committee approval was given from the Bolu University with decision number 2020/176.
Results
There were a total of 100 patients (44% female). In-hospital mortality was recorded as 7%. In univariate analysis for 1 month mortality, diabetes mellitus (p = 0.038), leucocyte count (p = 0.005), neutrophile count (p = 0.02), neutrophile-to-lymphocyte ratio (NLR) (p < 0.001), thrombocyte-to-lymphocyte ratio (TLR) (p = 0.001), C-reactive protein (CRP) (p = 0.002), lactate dehydrogenase (LDH) (p = 0.001), sequential organ failure assessment (SOFA) score (p = 0.001) and qSOFA score (p = 0.002) were found as independent risk factors. On admission, one point increase of NLR (p = 0.014, odds ratio (OR) = 1.371, 95% CI = 1.067–1.761) and one point increase of LDH (p = 0.047, OR = 1.011, 95% CI = 1.001–1.023) were associated with mortality on day 30 according to logistic regression analysis. The cut-off values were found as > 7.8 for NLR (83.33% sensitivity, 97.7% specificity) and > 300 U/L for LDH (100% sensitivity, 79.31% specificity) regarding the prediction of 30-day mortality.
Conclusion
In order to improve clinical management and identify the geriatric patients with COVID-19 who have high risk for mortality, NLR and LDH levels on admission might be useful prognostic tools.
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.
