RESUMO
Atrial fibrillation (AF) is a rhythm disorder observed mostly amongst adults. AF has been regarded as one of the most important medical problems because it leads to thromboembolism and paralysis risks. Although warfarin has been used in the past to cope with this health problem, new oral anticoagulant medicines have replaced it in the last few years. The new oral anticoagulants, namely, dabigatran etexilate, rivaroxaban, and apixaban, are currently being used in daily clinical practice and treatment guidelines. Since AF patients are supposed to receive long-term oral anticoagulant therapy, it is extremely important to provide them with accurate information and appropriate training regarding the treatment to decrease oncoming complications. This is a prospective study involving 168 patients who were admitted to the emergency department with AF and who were using oral anticoagulants. Findings indicate a lack of awareness in the patients regarding the effects and side effects of the drugs they take despite having been informed by the prescribing physician. We believe that informed action by patients with regard to the oral anticoagulants and their side effects will have an impact on the reduction in hospitalization observed. It will also make a substantial contribution to the quality of life of AF patients and to their use of medical services.
RESUMO
BACKGROUND AND OBJECTIVES: Uremic encephalopathy is the most important complication of renal failure and urgent dialysis treatment is required. Parathormone (PTH) contributes to the etiopathogenesis of uremic encephalopathy. PTH is a hormone that acts in the calcium balance in the organism. The aim of our study was to investigate the effect of serum adjusted and ionized calcium on the development of uremic encephalopathy in patients with acute renal injury (acute kidney injury network (AKIN) stage 3). MATERIALS AND METHODS: Our study was supported by Canakkale Onsekiz Mart University Scientific Research Projects Unit (ID:1278). Three groups were formed for the study. The first group was acute renal failure AKIN stage 3 (N: 23), the second group was AKIN stage 3, and the patients who had emergency hemodialysis (N: 17) and the third group (N: 9) had AKIN stage 3 hemodialysis due to uremic encephalopathy. In these patient groups, 25-hydroxy vitamin D, PTH, calcium, albumin, urea, creatinine, and blood-gas-ionized calcium were observed in their serum during the first application. Calcium, albumin, urea, creatinine, and ionized calcium in blood gas were also examined in serum at 24th and 72th hours. Data were analyzed using SPSS version 19.0. Kruskal-Wallis test and Mann-Whitney U test were applied for the variables that did not comply with normal distribution. p < 0.005 was accepted statistically. RESULTS: A statistically significant difference was found between the measurement creatinine values at the 24th and 72th hours of admission in AKIN stage 3 patients who applied to the emergency department (p = 0.008). A statistically significant difference was found in the measured calcium values (p = 0.013). A statistically significant difference was found in the measured ionized calcium values (p = 0.035). CONCLUSIONS: In our study, the effect of ionized calcium level on uremic encephalopathy in serum creatinine, calcium, and blood gas in patients presenting with acute renal injury, AKIN stage 3, was significant, but studies with new and large groups are needed.
