No full textDNA Damage, Glutathione, and Total Antioxidant Capacity in Anesthesia Nurses
No full textThe possibilities of a potential mutagenic/carcinogenic action of waste anesthetic gases in occupationally exposed anesthesia personnel have been previously reported in several studies. The aim of this study was to assess the DNA damage, reduced glutathione (GSH), and total antioxidant capacity (TAC) in anesthesia nurses. DNA damage was determined with comet assay, GSH levels were measured spectrophotometrically, and TAC was determined by using Randox kit. Anesthesia nurses (n = 40) showed increased DNA damage in terms of mean percentage of the total DNA in the comet tail compared to controls (n = 40) (p < .001). Mean TAC and GSH levels of the anesthesia nurses were significantly lower than that of the controls (p < .001, p < .05, respectively). The results of this study indicate that occupational exposure to anesthetic gases induce DNA damage, which may lead to changes in TAC and GSH levels
High-Dose Vitamin C Infusion for the Treatment of Covid-19: Beware of Paraben Intoxication
No full textSevere Theophylline Intoxication, Rhabdomyolysis, Disseminated Intravascular Coagulopathy and Death: Case Report
No full textBackground: Severe intoxication which is induced by theophylline which is used in the treatments of broncospastic pulmonary diseases is quite rare. In literature, there is limited number of rhabdomyolysis cases induced by theophylline toxicity. The statement of disseminated intravascular coagulopathy which develops after theophylline intoxication has not been detected in the literature. Case report: We present the case which has resulted with rhabdomyolysis, disseminated intravascular coagulopathy and death after overdose theophylline intake of a female patient at the age of seventeen. Conclusion: The overdose theophylline intake can cause quite mortal toxicity as a result of negative effects it causes on cardiovascular, neurological and metabolic systems. It should not be forgotten that in severe intoxications, rhabdomyolysis and disseminated intravascular coagulopathy can be developed, although the patient's condition is good, she/he should be monitored with close monitorization under intensive care conditions
Endothelial Activation and Stress Index (EASIX) to Predict the Outcome of Patients with COVID-19
No full textEndotheliopathy plays an essential role in the pathophysiology of COVID-19. The endothelial activation and stress index (EASIX) indicates endothelial dysfunction. We aimed to investigate the relationship between a high EASIX score and mortality in patients with COVID-19. We retrospectively reviewed COVID-19 patients admitted to the ICU (intensive care unit) of the Ankara Bilkent City Hospital. We recorded hematological and biochemical parameters at the ICU admission and further calculated EASIX with the following equation: EASIX = Lactate dehydrogenase (U/L) × creatinine (mg/dL)/platelet count (109/L). Statistical comparisons were made between the surviving and non-surviving groups in terms of EASIX. The median EASIX score was 1.2 (0.7–2.0) in the survivor group and a median of 2.5 (1.6–4.2) in the non-survivor group (p < 0.001). The mean log2-EASIX was 0.2 ± 0.9 in the survivor group and 1.3 ± 1.2 in the non-survivor group (p < 0.001). Lactate dehydrogenase, creatinine, Troponin I, D-dimer, procalcitonin, ferritin, and IL-6 were statistically significantly higher in the non-survivor group compared to the survivor group. The receiver operating characteristic (ROC) curve analysis showed that the cut-off value of the EASIX score was 2.05 (The area under the curve [AUC] = 0.764, p = 0.001, 95% CI: 0.662–0.847). Our study showed an association between high EASIX scores and poor prognosis in COVID-19 patients. Lactate dehydrogenase, creatinine, Troponin I, D-dimer, procalcitonin, ferritin, IL-6, EASIX, and log2-EASIX were statistically significantly higher in the non-survivor group compared to the survivor group. Being old and having chronic kidney disease increases the risk of death. Eventually, EASIX can be used to predict mortality in COVID-19 patients
Can Nutritional Screening Tools Predict the Prognosis of Critically Ill Patients with Sepsis?
No full textBackground and Objectives: Although nutritional status is critical to the clinical outcomes of septic patients, studies on this topic are limited. We aim to assess the prognostic value of five nutritional screening tools (NSTs) for septic patients both at the time of admission to the intensive care unit (ICU) and five days later. Materials and Methods: This prospective observational study included adult septic patients in the ICU. Patients were divided into two groups: survivors and non-survivors. Clinical, laboratory characteristics, and NST values [The Controlling Nutritional Status (CONUT), Prognostic Nutritional Index (PNI), Nutritional Risk Screening (NRS-2002), Geriatric Nutritional Risk Index (GNRI), and Nutrition Risk in the Critically Ill (NUTRIC)] were recorded at admission and on Day-5, and intergroup and intragroup comparisons were performed. Results: A total of 126 patients were included in this study: 97 in the survival group and 29 in the non-survival group. The non-survivors had higher CONUT and NUTRIC scores and lower PNI scores. Multivariate analysis found higher Day-5 NUTRIC scores independently associated with mortality. ROC analysis identified NUTRIC > 6 as a mortality predictor. Conclusions: Although several markers differed significantly between survivors and non-survivors, our findings show that a high Day-5 NUTRIC score was the only factor independently associated with mortality among NSTs
Factors Determining Nephrotoxicity and Mortality in Critical Care Patients Receiving Colistin
No full textIntroduction: We aimed to determine risk factors for nephrotoxicity and factors affecting mortality in patients who received colistin.
Methodology: Critical patients who received colistin were enrolled. Pregnancy, age < 18 years, basal creatinine level > 2 mg/dL, colistin use for < 48 hours, and previous renal replacement therapy were exclusion criteria. KDIGO stages were determined according to creatinine levels. Patients were grouped as those with no acute kidney injury (Group N0) and those with acute kidney injury (Group N). Their demographic data, APACHE II and SOFA scores, treatments, and laboratory results were recorded.
Results: A total of 91 patients were included: 27 in Group N0 and 64 in Group N. Demographic data were similar between groups; however, higher admission APACHE-II scores (OR:1.179, 95% CI:1.033-1.346, p = 0.015) and need for vasopressors (OR:5.486, 95% CI:1.522–19.769, p = 0.009) were found to be independent risk factors for nephrotoxicity. Higher APACHE II scores (OR:1.253, %95 CI:1.093-1.437, p = 0.001), presence of coronary artery disease (OR:7.720, % 95 CI: 1.613-36.956, p = 0.011), need for vasopressors (OR: 4.587, % 95 CI: 1.224 – 17.241, p = 0.024), hypoalbuminemia (OR: 4.721, % 95 CI: 1.088 – 20.469, p = 0.038), and higher direct bilirubin levels (OR: 1.806, % 95 CI: 1.055 – 3.092, p = 0.031) were independent risk factors for mortality.
Conclusion: When use of colistin is considered in ICU patients, presence of modifiable risk factors for nephrotoxicity such as hypoalbuminemia, nephrotoxic drug administration, and presence of shock should be determined and managed to prevent nephrotoxicity.</jats:p
