Factors Related to Resuscitation Success and Prognosis of Cardiopulmonary Arrest Cases.

Background: In cases where return of spontaneous circulation (ROSC) is provided in the Emergency Department (ED) after cardiopulmonary arrest (CA), it is important to investigate the parameters affecting ROSC rates, to determine the factors affecting the survival status and prognosis in the short and medium term, and to determine to what extent these factors affect the prognosis. Materials and methods: This is a cross-sectional study that retrospectively investigates the factors affecting the success of resuscitation over a 5-year period in out-of-hospital cardiac arrest (OHCA) cases. Results: We determined that ROSC was achieved in 26.1% of 1616 adult cardiopulmonary arrest cases, 14.8% survived the first 24 hours, and 3.8% were discharged from the hospital. Conclusion: We determined that ROSC decreased by 21% with a 1-mg increase in the amount of adrenaline used, by 98% with a 1 mmol/L increase in HCO3 (std) value, by 27% with a 1 mmol/L increase in BE (B) value, and by 15% with a 1 mmol/L increase in lactate value. In terms of short-term survival, we found that a 1 mmol/L increase in lactate value reduced the probability of survival by 12%, and a 1 mEq/L increase in K value decreased the probability by 29%. With regard to the probability of survival in the medium term, we determined that the growth in age by 1 year decreased the probability by 4%, and the increase in K value by 1 mEq/L decreased the probability by 35%.

Effect of Serum Netrin-1 Levels on Diagnosis and Prognosis in Patients Admitted to the Emergency Service for Acute Coronary Syndrome.

Background Netrin-1 is a recently discovered diagnostic biomarker that indicates atherosclerosis, angiogenesis, and ischemia-reperfusion damage. There are no human studies about Netrin-1 in acute coronary syndrome (ACS). The purpose of the present study was to investigate Netrin-1 levels in the early diagnosis and successful reperfusion of ACS. Method The study was conducted with 188 patients diagnosed with ACS and 50 healthy subjects at the emergency unit in a prospective design. Blood samples were collected from the patient group at initial admission and after angiography. The control group consisted of healthy adult subjects without any disease. Netrin-1 levels were studied in both groups. Results The Netrin-1 levels of the patient group at the time of admission were found to be higher than of the control group (p<0.001). In the patient group, netrin-1 levels measured at initial admission (1.53±0.19) and after angiography (1.49±0.19) were determined to be statistically significant (p:0.049). In the patient group, where the Thrombolysis in Myocardial Infarction (TIMI) 3 flow was established after angiography, netrin-1 levels were detected to be low (p:0.039). Netrin-1 levels obtained at the time of admission were determined to be significantly different in the Global Registry of Acute Coronary Events (GRACE) moderate and high-risk groups in comparison to the low-risk group (p:0.017). Conclusion Netrin-1 was shown to increase in the early diagnosis of ACS and to decrease in patients for whom reperfusion was established after angiography. Therefore, Netrin-1 can be an important biomarker as an indicator of diagnosis and successful reperfusion in ACS.

The Effect of Beta-Trace Protein on Diagnosis and Prognosis in Patients with Acute Coronary Syndrome.

Objective The purpose of this study was to determine the effect of beta-trace protein (BTP) levels at the time of admission and at 8th hour on diagnosis and prognosis in patients who were under treatment and follow-up with acute coronary syndrome (ACS) diagnosis at coronary intensive care unit and emergency department. Materials and Methods This study was conducted between June 2014 and December 2014 at the Emergency Department of Konya Training and Research Hospital. Demographic characteristics, background, vital findings, laboratory findings, blood BTP levels, coronary angiography results, and echocardiography findings of the patients diagnosed with ACS were recorded. Risk classification was performed for patients with ACS and their mortality rates were recorded. Relation of BTP level with risk classification and mortality was evaluated. Results A total of 174 individuals, 138 patients and 36 control subjects, were included in the study. No significant difference was detected between BTP levels at the time of admission and at 8th hour in the patient group (p=0.883). There was no difference between the patient and control groups in terms of the BTP level (p=0.335). Ten patients (7.2%) died in the patient group. BTP levels measured at the time of admission and at 8th hour were not different for dead and living patients (admission p=0.085, 8th hour p=0.141). Conclusion We determined that there was a lack of biochemical markers that could be used for the prognosis of serum BTP levels in patients admitting to the emergency unit with ACS.

Relationship between the neutrophil-to-lymphocyte ratio in acute pancreatitis and the severity and systemic complications of the disease.

BACKGROUND/AIMS: In 80% of the patients, Acute pancreatitis (AP) occurs as a self-limiting disease that does not require any specific treatment; however, in 20% of the cases it occurs in its clinically severe form that may lead to local or systemic complications. The aim of this prospective study was to examine the relationship between the neutrophil to lymphocyte ratio (NLR) and the systemic complications and severity of AP. MATERIALS AND METHODS: This prospective study included 100 patients with AP. Age, sex, NLR, Ranson scores and the revised Atlanta classification of the patients were recorded. The patients were divided into two groups according to the Ranson scores as mild and severe AP. According to the Revised Atlanta classification, the patients were divided into two groups as mild and moderate+severe AP. RESULTS: According to the Ranson score, NLR at the time of admission and at the 48th hour in the severe group was found to be statistically higher than the mild AP group (p<0.01). The receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off value of NLR at the emergency department in order for it to be used for distinguishing AP patients with and without systemic complications. The area under the ROC curve was 0.81. Sensitivity and specificity were 87.50% and 69.05%, respectively, when the NLR cut-off value was >7.13. CONCLUSION: Neutrophil to lymphocyte ratio is associated with severe AP. We also regard NLR as a valuable parameter for predicting the development of systemic complications in patients with AP.

The experiences in a toxicology unit: a review of 623 cases.

BACKGROUND: To evaluate the etiological and demographic characteristics of adult poisoning patients followed up in a toxicology unit in Konya, Turkey. METHODS: Patients (≥ 15 years old) followed up with the diagnosis of poisoning in our toxicology unit in 2011 were included in this retrospective study. The patients' medical records were investigated. Age, gender, medical history, the first medical center the patient had been admitted to, the routes and causes of poisoning, the toxins involved, the number of the pills taken, treatments, complications, the length of stay in the hospital and the outcome were recorded. RESULTS: A total of 623 patients were included in the study. The mean age of patients was 28.1 ± 15.1. Four hundred and forty-five (71.4%) of patients were female, 541 (86.9%) of them were poisoned via the oral route and 75 (12.0%) of them were poisoned by inhalation. The causes of poisoning were drugs in 408 (65.5%) patients, pesticides/insecticides in 58 (9.3%) patients and carbon monoxide in 49 (7.9%) patients. The commonly used drugs were as follows: analgesics (57.2%), antidepressants (25.4%) and gastrointestinal system drugs (15.8%). The poisonings were suicidal in 489 (78.5%) patients, accidental in 120 (19.3%) patients and overdose in 14 (2.2%) patients. The number of women was higher in the suicide group. At the end of the treatment, 604 (97.0%) of the patients were discharged and 3 (0.4%) of them died. The duration of follow-up was 39.2 ± 37.5 h. CONCLUSION: The most common causes of poisoning are drugs, pesticides/insecticides and carbon monoxide. Health and educational policies at a national level are needed in order to prevent this medicosocial problem. Furthermore, specially equipped toxicology units should be constructed for the treatment and follow-up of the poisoned patients in order to reduce the morbidity and mortality to a significant extent.

The Importance of H-FABP in Determining the Severity of Carbon Monoxide Poisoning.

BACKGROUND: In this study, we aimed to investigate the importance of the use of heart-type fatty acid binding protein (H-FABP) in evaluating the myocardial damage in patients admitted to the emergency department with moderate to severe carbon monoxide (CO) poisoning. METHODS: All patients admitted to the emergency department with severe acute CO intoxication were enrolled the study. The H-FABP and cardiac biomarker levels were assessed at 0, 6th and 24th hours. The patients were divided into groups as those with normal echocardiography findings and with wall motion abnormalities. The differences between the groups for these parameters were compared. RESULTS: The mean age of 80 patients was 32.3 ± 12.9 years old. 42 of them were male. On admission, 29 (36.3%) had elevated serum troponin I levels and 56 (70.0%) had elevated serum H-FABP levels. At 6thhour, 4 (5.0%) of 80 patients had higher serum H-FABP levels and 23 (28.8%) of them had higher serum Troponin I levels than 0 hour. The patients with wall motion abnormality had significantly higher serum H-FABP levels compared to the patients with normal echocardiography findings at 6th and 24th hours (p = 0.001 and 0.009). While the serum COHb and H-FABP levels tended to decrease continuously in time (p < 0.001), the serum troponin I levels increased at 6th hour and then decreased at 24th hour (p = 0.017). CONCLUSION: The serum H-FABP levels are useful in identifying the myocardial damage in patients admitted to the emergency department with moderate to severe carbon monoxide poisoning at an early phase. KEYWORDS: Carbon monoxide; Poisoning; H-FABP; Myocardial injury.

Effects of phototherapy on the growth plate in newborn rats.

The aim of the present study was to evaluate the effect of phototherapy and oxidative stress on the growth plate of newborn rats. Forty newborn Sprague-Dawley rats were randomized into a phototherapy group and a control group. Twenty of the rats received phototherapy for 7 days. All zones of the growth plate were assessed with quantitative histomorphometric analysis. Individual zonal lengths were measured for the reserve zone (RZ), the proliferative zone (PZ), the hypertrophic zone (HZ), ossifying cartilage (OC), and total zone (TZ) of the growth plate. Levels of plasma malondialdehyde (MDA), an index of oxidative stress, were also evaluated. Compared with zonal lengths on day 7 after phototherapy between the two groups, the phototherapy group had significantly lower values than those of controls for RZ (5.13 +/- 0.36 vs. 6.4 +/- 0.85 mm x 10(-2); P < 0.001), PZ (20.6 +/- 3.0 vs. 29.25 +/- 1.68 mm x 10(-2); P < 0.001), HZ (15.4 +/- 1.44 vs. 20.87 +/- 1.12 mm x 10(-2); P < 0.001), OC (47.08 +/- 4.25 vs. 62.06 +/- 3.7 mm x 10(-2); P < 0.001), and TZ (88.15 +/- 6.56 vs. 118.48 +/- 4.50 mm x 10(-2); P < 0.001). Plasma MDA levels were correlated with the size of the PZ in the phototherapy group (r = -0.53, P = 0.01). In a multivariate regression model for all rats, being in the phototherapy group was the best predictor of the size of the TZ (beta = -0.94, P < 0.001), with the total variance explained being 88%. These results suggest that in newborn rats, receiving phototherapy is associated with early impairment of growth plate structure, and oxidative stress may be the main risk factor for growth plate injury.

Effect of deferoxamine on Na+K+ATPase activity after cerebral ischemia in rabbits.

OBJECTIVE: To study the effects of deferoxamine on tissue sodium-potassium adenosine triphosphatase (Na+-K+ ATPase) activity on cerebral ischemia in rabbits. METHODS: We cared for the animals in the Pharmacology Department of the Medical School of Selcuk University in 2004. We used 30, New Zealand, 7-day-old male rabbits in the experiment. We anesthetized all the animals with xylazine hydrochloric acid and ketamine. We divided the rabbits equally into 3 groups. In group 1 (n=10) (sham group), we observed baseline levels, and did not apply ischemia. In group 2 (n=10) (untreated group) we produced cerebral ischemia by clamping the bilateral common carotid arteries for 60 minutes, and in group 3 (n=10), we administered deferoxamine (DFO) 50 mg/kg intravenously immediately after opening the clamps. RESULTS: The Na+-K+ATPase activity increased after DFO treatment (p=0.045). CONCLUSION: We conclude that Na+-K+ATPase activity in cortical brain tissue was higher in DFO-treated rabbits compared with untreated animals after ischemia.

The influence of aldosterone on the development of left ventricular geometry and hypertrophy in patients with essential hypertension.

The identification of risk factors for the initiation of left ventricle hypertrophy (LVH), which is an independent risk factor for cardiovascular mortality and morbidity in hypertensive patients, is very important. The objective of the present study was to identify the relationship of aldosterone with LVH and different geometrical patterns of left ventricle that develop in patients with essential hypertension. A total of 83 patients with essential hypertension (44 females, mean age, 51 +/- 8 years, 39 males, mean age, 57 +/- 10 years) were included in this study. Thirty-two had LVH. When evaluated according to the geometrical patterns of LVH, 18 patients had concentric LVH, 14 had eccentric LVH, and 17 had concentric remodeling. Thirty-four patients had normal left ventricle geometry. Two weeks after the cessation of antihypertensive medications, sodium, potassium, and proteinuria in 24-hour urine samples and plasma aldosterone levels and plasma renin activity were measured. Plasma aldosterone levels of the patients with LVH were found to be significantly higher (9.92 +/- 6.34 ng/dL versus 5.83 +/- 3.5 ng/dL, P < 0.01). The difference between plasma renin activities was not statistically significant. Linear regression analysis revealed that plasma aldosterone level and age were independent parameters increasing left ventricle mass index. The plasma aldosterone levels of patients with concentric hypertrophy of the left ventricle were significantly higher than those of patients with normal geometry and concentric remodeling. There was no significant difference between plasma renin activities. Twenty-four hour urine protein concentrations of the patients with LVH were found to be significantly higher and sodium to be significantly lower. Plasma aldosterone levels seem to be correlated with LVH especially with concentric hypertrophy of the left ventricle in patients with essential hypertension.
