The Relationship between albumin-Bilirubin grade and survival in hepatocelluler carcinoma patients treated with sorefanib.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common hepatic malignancies and the sixth most common cancer worldwide. Prognosis is affected by tumor stage, hepatic disfunction and patient performance. Albumin - bilirubin grade was developed to assess the hepatic function in patient with HCC. Aims: The purpose of this study was to examine the relationship between albumin-bilirubin (ALBI) grade and survival in HCC patients receiving sorafenib. We also planned to investigate whether ALBI scores in advanced stage patients are prognostic and predictive. PATIENTS AND METHODS: Patients presenting to the Karadeniz Technical University Medical Faculty Medical Oncology Clinic and diagnosed with HCC in 2010-2018 were included in the study. Fifty-six patients using sorafenib with Eastern Cooperative Oncology Group (ECOG) performance scores of 0, 1, or 2, who had not previously received systemic therapy were enrolled. RESULTS: Patients' median age was 64.8 years (range: 23-86), and 80.4% were men. The highest proportion of patients were infected with hepatitis B virus (46.4%), 37 patients were ECOG 1 (66.1%), and 40 were ALBI grade 2 (71.4%). The change occurring in ALBI scores after sorafenib therapy compared to pre-sorafenib values was found to affect progression-free survival. Prognosis was better in the group with decreasing ALBI scores than in the increasing score group (p: 0.028). Multivariate regression analysis revealed that the change occurring in ALBI scores after sorafenib therapy compared to pre-sorafenib values was predictive of progression-free survival independently of alpha-fetoprotein (AFP) levels. CONCLUSION: This study shows that ALBI grade affects survival independently of AFP, Hand-Foot Syndrome (HFS), and other prognostic factors. ALBI grading can be used as a prognostic parameter in patients using sorafenib.

Retrieval of a malpositioned left subclavian artery stent from the ascending aorta: combined percutaneous and surgical management.

Chronic upper limb ischemia is an uncommon clinical condition and is most often caused by subclavian artery stenosis. Surgical and percutaneous treatment modalities have been shown to be effective for the management of subclavian artery occlusion. Because of lower mortality and morbidity rates, percutaneous interventions for subclavian arterial occlusions are more acceptable than surgery. Chronic total occlusions of the subclavian artery are challenging to treat percutaneously because of the structure and complexity of the lesion. The complexity of the lesion causes its own complications. In this paper, we report a case of a completely occluded left subclavian artery that was complicated by a malpositioned stent hanging into the aortic arch and the ascending aorta during percutaneous intervention, which was successfully managed by our heart team.

Increased ischemia-modified albumin levels in patients with gastric cancer.

Reactive oxygen species (ROS) are found in the development stages of carcinogenesis. Fifty two patients with gastric cancer and 35 controls were enrolled in this trial. IMA, MDA, Total Oxidant Status (TOS), Total Antioxidant Status (TAS) and Oxidative Stress Index (OSI) were evaluated. There was a significant increase in IMA and MDA levels in the patient group (0.405±0.111, 0.271±0.066; p= 0.0001 and 0.207±0.251, 0.077±0.103; p= 0.004 respectively). TOS was also higher in the patient group but it was not statistically different. TAS was statistically lower and there was significant difference in OSI (0.621±0.394, 0.996±0.37; p=0.0001 and 9.68±18.2, 2.9±3.85; p=0.001 respectively). The areas under receiver operating characteristics curves for the determination of gastric cancer were 0.842 for IMA and 0.708 for MDA. Increased levels of IMA, MDA and oxidative stress index were detected and this condition is associated with the impairment of oxidant-antioxidant balance.

Evaluation of risk factors associated with first episode febrile seizure.

OBJECTIVE: Febrile convulsion (FC) is one of the most common neurological findings in children. This study was aimed to investigate the difference in laboratory parameters between Febrile Seizure and control groups. PATIENTS AND METHODS: In this study, 169 children admitted to the pediatric emergency department with their first episode of FS and 189 control groups were retrospectively analyzed. The demographic characteristics and laboratory parameters of children were obtained from their files. RESULTS: Upper respiratory tract infection (URTI) was determined the most common disease (81.6%) in the FC group followed by acute gastroenteritis (AGE) (15.4%) and urinary tract infection (UTI) (3%), respectively. Similarly, URTI was detected as the most common disease (81.8%) in control groups. It was determined that there was no statistically significant difference between the two groups in terms of diseases. The leukocyte and neutrophil counts of the children with FC were significantly higher but the mean corpuscular volume of lenfosit and lenfosit/neutrophil ratio was significantly lower than the control groups (p= 0.009, <0.001, 0.001, <0.001, <0.001, respectively). Children with FC had significantly higher blood glucose, urea, creatinine, creatine kinase, alkaline phosphatase and albumin levels compared with the control groups (p<0.001, in all parameters). On the other hand, the potassium, sodium and chlorine levels of the Children with FCs were significantly lower than control groups (p=0.017, <0.001, p <0.001, respectively). CONCLUSIONS: To conclude, febrile patients with high leukocyte counts, high neutrophil counts, and several biochemical parameters should be carefully monitored for FCs due to the increasing seizure risk.

Hepatitis B Reactivation in HBsAg-negative Anti-HBc-positive patients receiving cytotoxic chemotherapy for solid tumors.

PURPOSE: The prevalence of hepatitis B virus (HBV) reacti- vation in HBsAg-negative/anti-HBc-positive patients receiving chemotherapy for solid tumors is not fully known. The aim of this study was to investigate the incidence and outcomes of HBV reactivation in these patients. METHODS: Data among 645 HBsAg-negative/ anti-HBc-positive patients who underwent intravenous chemotherapy were retrospectively analyzed. Patients were categorized into two groups, based on received antiviral prophylaxis (n = 43) or not (n = 602). HBV reactivation was defined as the presence of detectable serum HBV DNA or HBsAg seroconversion from negative to positive, with or without increased liver enzymes. RESULTS: HBV reactivation was detected in 3 patients (0.49%) among non-antiviral prophylaxis group and in none of those with antiviral prophylaxis. Two of the HBV reactivation detected patients were successfully treated with rescue therapy, while the third died due to liver failure. CONCLUSIONS: HBV reactivation is rare in HBsAg-negative and anti-HBc-positive patients receiving chemotherapy for solid tumors. However, considering the fatal outcomes patients must be closely monitored in terms of HBV-DNA positivity and/or HBsAg seroreversion and pre-emptive antiviral therapy must be initiated as soon as HBV reactivation occurs.

Neurocognitive Consequences of Childhood Leukemia and Its Treatment.

As survival rates have improved in pediatric patients with leukemia, late side effects from chemotherapeutics and radiotherapy have become important considerations. We investigated these side effects and evaluated their impact on neurocognitive functions. The observational study included 68 patients with acute leukemia who were treated at Eskisehir Osmangazi University Medical Faculty. The study also included 62 of the patients' closest age siblings as a control group. Demographic and clinical data, chemotherapy protocol, use of radiotherapy were recorded, neurological and ophthalmological examinations, cranial imaging, electroencephalography, visual evoked potential, and hearing investigations were performed, and neurocognitive functions were evaluated. At least one or more late effects detected by a neurologic abnormality on physical exam, cranial magnetic resonance imaging, neurological tests, or neurocognitive tests was significantly more likely in the patient group (82.4%) compared to the control group (29%, p < 0.001). A higher rate (82.4%) of delayed neurological and cognitive problems occurred in children who received radiotherapy, intrathecal and/or systemic chemotherapy during leukemia treatment compared to age-matched siblings. Patients being treated for leukemia should be periodically evaluated for treatment-related side effects. Prophylactic interventions such cognitive training and maintenance of academic growth may offer the best hope of preventing late effects.

Fabrication of oxide layer on zirconium by micro-arc oxidation: Structural and antimicrobial characteristics.

The aim of this study was to cover the surfaces of zirconium (Zr) with an antimicrobial layer for biomedical applications. For this purpose, the micro-arc oxidation (MAO) process was employed in a sodium silicate and sodium hydroxide containing base electrolyte with and without addition of silver acetate (AgC2H3O2). In general, synthesized MAO layers were composed of zirconium oxide (ZrO2) and zircon (ZrSiO4). Addition of AgC2H3O2 into the base electrolyte caused homogenous precipitation of silver-containing particles in the MAO layer, which exhibited excellent antibacterial efficiency against methicillin-resistant Staphylococcus aureus (MRSA) as compared to the untreated and MAO-treated Zr.

[Hospital nurses' perception of public health]. / La perception de la santé publique des infirmières à l'hôpital.

The objective of this work was to study hospital nurses' perceptions of public health based on a pedagogical exercise. A qualitative study, lead by students of a training institute for nursing care (IFSI), was conducted using semi-directed interviews of hospital nurses from different departments of a provincial hospital. The main results show that for one-third of the nurses interviewed, the hospital is not a setting for public health practice. In terms of their definition of public health, it is closely linked to the concept of prevention, with primarily individual approaches. This definition is very close to the public health activities that they conduct at the hospital and which are centred on information and disease prevention, on education related to pathologies and the relationship between the provision of care and listening to the patients and their families. Few nurses place their public health activities within the scope of the areas of hospital cleanliness, the welcoming of the patients, the organisation of services, and the improvement of the quality of care. The potential tracks which have emerged from this work lead to the need for the strengthening of training in patient education, in the hospital's work networking with external partners, and in better development of public health activities undertaken in the hospital setting.

Bolus fluorouracil induced syncope and pulseless ventricular tachycardia: a case report.

5-fluorouracil is an anti-cancer drug commonly used in oncology practice. Typical side effects are myelosupression, nausea, vomiting, diarrhea and stomatitis. Cardiotoxicity is the other toxicity. Cardiac side effects are ST segment changes, rhythm abnormalities, supraventricular and ventricular dysrhytmias. Pulseless ventricular tachycardia and ventricular fibrillation releated with bolus fluorouracil were not detected in the literature. Here we discussed a 46 year-old male patient that has no known cardiac history. After bolus fluorouracil administration, syncope and pulseless ventricular tachycardia developed in this patient. There are a few explanations about the cardiotoxicity of fluorouracil. One of these is the effect on nitric oxide. It causes a reduction in the levels of endothelial NO and this leads coronary vasospasm. Another explanation is protein kinase C mediated vasospasm. In animal studies toxic myocarditis like lesions were detected with fluorouracil infusions. Finally both myocardit and vasospasm may lead cardiac problems like sudden cardiac deaths. Bolus 5-fluorouracil is as cardiotoxic as 5-fluorouracil infusion and we must be careful about the arrhytmia after the bolus administration.
