Aim: This work was designed to investigate the relationship between cardiac outcomes and Naples Prognostic Score (NPS) among heart failure (HF) patients. Materials & methods: This retrospective observational study enrolled 298 consecutive individuals hospitalized for New York Heart Association class 3–4 HF. The primary outcome was all-cause mortality. Secondary outcomes were rehospitalization and in-hospital death. Results: The high NPS group had a statistically greater rate of all-cause mortality (p < 0.001). In Cox regression analysis, integrating NPS considerably improved the performance of the full model over the baseline model (adjusted hazard ratio = 2.28; p = 0.004). Based on time-dependent receiver operating characteristic curve analysis, the NPS model outperformed the baseline and CONUT score models in discriminatory power in predicting the probability of survival. Conclusion: NPS was associated with short- and midterm mortality as well as rehospitalization.

Introduction: In-stent restenosis (ISR) still constitutes a major problem after percutaneous vascular interventions and the inflammation has a pivotal role in the pathogenesis of such event. The C-reactive protein/albumin ratio (CAR) is a newly identified inflammatory biomarker, and it may be used as an indicator to predict ISR in subjects with coronary artery stenting. In light of these data, our main objective was to investigate the relationship between the preprocedural CAR and ISR in patients undergoing successful iliac artery stent implantation. Methods: In total, 138 consecutive patients who had successful iliac artery stent implantation in a tertiary heart center between 2015 and 2018 were enrolled in the study. The study population was categorized into two groups; patients with ISR and those without ISR during follow-up. The CAR was determined by dividing CRP by serum albumin. Results: In the multivariable regression analysis; the CAR (HR: 2.66, 95% CI: 1.66-4.25, P < 0.01), stent length (HR: 1.01, 95% CI: 0.99-1.02, P = 0.04), and HbA1c levels (HR: 1.22, 95% CI: 0.99-1.51, P = 0.04) were independently related with ISR. A receiver operating curve analysis displayed that the CAR value of >0.29 predicted ISR with sensitivity of 97.5% and specificity of 88.8% (AUC 0.94, P < 0.01). Conclusion: Our findings provide evidence that the CAR may be an applicable inflammatory biomarker in predicting ISR in subjects undergoing iliac artery stenting for the treatment of peripheral artery disease (PAD). Also, the stent length and poor glycemic control were found to be associated with ISR.

IAB is common in patients with STEMI and along with the presence of diffuse coronary artery disease is associated with new onset of AF.

Objective: In this study, we aimed to determine whether admission hemoglobin versus post-percutaneous coronary intervention (PCI) hemoglobin level at 24 hours is a predictor of in-hospital mortality for patients with ST elevation myocardial infarction (STEMI) without evidence of clinical hemorrhage who underwent primary PCI. Methods: In this study, we included 1,444 consecutive patients with STEMI who underwent primary PCI at a tertiary heart hospital. The primary outcome of the study was the in-hospital all-cause mortality. We used the penalized maximum likelihood estimation (PMLE) logistic regression method to examine the relationship between primary outcome and candidate predictors. Results: In total, 172 (11.9%) patients died during the in-hospital course. According to a PMLE logistic regression analysis, age, KILLIP class ≥2, pre-PCI thrombolysis in myocardial infarction (TIMI) flow <3, systolic blood pressure, creatinine, glycoprotein IIb/IIIa inhibitor use, and post-PCI hemoglobin levels at 24 hours were predictors of in-hospital mortality. The relative importance of post-PCI hemoglobin at 24 hours (contributing 6% of the explainable outcome in the model) was significantly higher than admission hemoglobin (contributing only 0.1% of the explainable outcome in the model). Conclusion:This study demonstrated that post-PCI hemoglobin levels were independently associated with in-hospital survival in patients with STEMI without evidence of bleeding following primary PCI. In addition, post-PCI hemoglobin was a better predictor of in-hospital mortality than admission hemoglobin for patients with STEMI who underwent primary PCI.

The one of the aim of nuclear medicine is diagnosis of an abnormal metabolic activities in target organs. In a routine nuclear medicine imaging procedure, a radiopharmaceutical is used. Radiopharmaceutical's radionuclide part emits gamma radiation. This radiation is dedected by Gamma Camera or Single Photon Emission Computed Tomography (SPECT). A computed tomography (CT) device was added to the SPECT(SPECT-CT). To combine anatomical images. Image quality of this device is important for accurate diagnosis and treatment of diseases. By means of quality control tests, performance changes of device are dedected. A various quality control parameters such as uniformity, sensivity, resolution, linearity have been developed for Gamma cameras, SPECT. Quality control test results are should be verify by comparing acceptable results. In this study, quality control tests of SPECT-CT are performed as proposed by the National Electrical Manufacturers Association (NEMA) and it was aimed to investigate some correction methods.

ÖZAmaç: Radyasyonlu ortamda çalışan sağlık personelinin radyasyon konusundaki bilincini değerlendirmek için bir anket çalışması yapılmıştır. Ankete Radyoterapi ve Radyoloji bölümlerinde çalışan Teknikerler ile bu bölümde okuyan öğrencilerin katılımı sağlanmıştır. Bu iki grup için elde edilen anket sonuçlarının karşılaştırılması amaçlanmıştır. Materyal ve Metot: Bu çalışma, bölüm, deneyim ve eğitim durumuna göre değerlendirilmiştir. Çalışma verileri değerlendirilirken tanımlayıcı istatistiksel metotların ( frekans, yüzde) yanı sıra verilerin meslek, tecrübe ve eğitim düzeyleri ile karşılaştırılmasında fark bulunup bulunmadığı ki-kare testleri kullanılarak araştırılmıştır. Elde edilen verilerin analizinde SPSS 22.0 programı kullanılmış ve P değerinin 0.05'in altında olduğu durum istatiksel anlamlı sonuçlar olarak değerlendirilmiştir. Bulgular: Anket sonuçlarına göre; Teknikerler, öğrencilerden istatistiksel anlamda daha çok doğru yanıt vermişlerdir. Bu durum aldıkları eğitimin daha kaliteli olması ile açıklanabilir. Bunun yanında, teknikerlerin bilgi düzeylerinin tecrübe ile arttığı ancak temel bilgilerin yerinin doldurulamadığı görülmektedir. Sonuç: Hizmet içi ve hizmet dışı olarak radyasyonlu ortamda çalışan sağlık personelinin radyasyon güvenliği ile bilgilendirmeye ihtiyacı vardır. Bu bilgilerin belli aralıklarla yenilenmesi fayda sağlayacaktır. Ayrıca radyasyon ile çalışan personelin zaman zaman mesleki bilinçlendirme eğitim, seminer ve kongrelere katılarak mesleki bilgilerinin güncellenmesi gerektiği görülmektedir. Anahtar kelimeler: Radyasyon, radyasyon bilinci, radyasyondan korunma, radyoterapi ABSTRACT Objective: A survey study was conducted to evaluate the awareness of the health personnel working in the radiation environment on radiation. The technicians working in the departments of radiotherapy and radiology and the students studying in this department were included in the survey. The aim of this study was to compare the results of the two groups. Materials and Methods:This study was evaluated according to department, experience and educational status. In the evaluation of the study data, whether there is any difference between the descriptive statistical methods (frequency, percentage) and the comparison of data with occupation, experience and education levels, the chi-square tests were used.SPSS 22.0 program was used in the analysis of the data obtained and the value of P value below 0.05 was evaluated as statistically significant results. Results: According to the results of the survey; technicians statistically gave more accurate answers than students. This can be explained by the higher quality of the education they received. Besides, it is seen that the level of knowledge of technicians increased with experience but basic knowledge could not be replaced. Conclusion: Personnel working in radiation environments need to be informed about radiation safety. Periodic renewal of knowledge will be beneficial. Moreover, it is seen that the personnel working with radiation should update their professional ...
