Background and Objectives: It has been demonstrated that parameters such as the Controlled Nutrition Status (CONUT) score and Prognostic Nutrition Index (PNI) are beneficial for the assessment of patients' nutrition. In this study, our objective was to investigate the potential benefits of CONUT and, as a prognostic marker of acute pancreatitis, the PNI. Materials and Methods: The data of 361 patients were analysed retrospectively. The PNI and CONUT scores of these patients were retrospectively calculated. They were categorised as CONUT-high (≥3) and CONUT-low (≤2). A PNI ≥ 45 was considered high and a PNI < 45 low. The AP severity and organ failure due to disease were evaluated based on Atlanta 2012. Results: According to the CONUT score, it was found that 209 patients had normal to mild, whereas 152 patients had severe malnutrition. A total of 293 patients had mild AP and 68 thereof had severe AP. The patients with a high CONUT score used more antibiotics, were hospitalised more in intensive care units and experienced organ failure more frequently. There were no intensive care hospitalisations, mortalities, surgical needs and local complications among the patients with a higher PNI score. Conclusions: CONUT and the PNI have proven to be useful prognostic markers not only for predicting nutritional status but also for estimating the severity and results of AP. [ABSTRACT FROM AUTHOR]

Aim: Percutaneous endoscopic gastrostomy (PEG) is a method that can be applied for nutritional purposes in patients who cannot be fed orally for various reasons but whose gastrointestinal system functions are normal. In this study, we aimed to determine the etiological causes and long-term outcomes (efficacy, safety, lifespan) of PEG in patients over 65 years of age. Methods: The data of patients aged 65 years or older who had PEG in our unit between 2015 and 2019 were analyzed retrospectively. The demographic information of the patients, the units they are being followed in, the underlying diseases, additional diseases, if any, complications-related to the procedure and the average life span were evaluated. Results: During this period, 140 patients had been PEG inserted. 51% of patients were male and the average age was 73.7±9.2 years, and the average age of women was 76±7.2 years. The most frequent cause of PEG insertion is a neurological disease. PEG insertion was the most common in cerebrovascular events, with a rate of 39%. PEG was implanted in 30% for Alzheimer's disease, and 14% for malignant reasons. 28% of the patients lived less than a month. In total, 76% of patients died. The average life expectancy of patients who died after PEG was 221.3±330.7 days. Conclusion: PEG is the gold standard in patients with normal gastrointestinal system functions in long-term enteral nutrition. However, in patients with a life expectancy of less than 1 month, the decision to place PEG or not should be made carefully. [ABSTRACT FROM AUTHOR]
