Background: Prognostic scoring systems are applied in intensive care units (ICUs) to monitor patients’ responses to treatment and guide treatment modalities. These scoring systems are also used as predictors in sepsis, where mortality rates are high. This study aims to compare the scores (APACHE II, SOFA, SAPS II, OASIS) in terms of their role in predicting overall mortality in patients admitted to ICUs with a diagnosis of sepsis or septic shock. Methods: Among 740 patients admitted to the tertiary intensive care unit within a 2-year period, 165 patients diagnosed with sepsis and septic shock were included in the study. Demographic data, comorbidities, SOFA, SAPSII, OASIS, and APACHE II scores, invasive or noninvasive mechanical ventilation requirements and durations, ICU admissions, hospital stays, and 28-day mortalities were retrospectively evaluated. Results: All scoring systems were positively correlated with mortality and CCI score. SAPS II and OASIS showed a higher correlation with mortality compared to other scoring systems, correlated with ICU admission and mechanical ventilation, unlike other scoring systems. The AUC values for the APACHE II, SOFA, SAPS II, and OASIS were 0.803, 0.873, 0.902, and 0.879, respectively. No statistically significant difference was found between the scores (p > 0.05). Conclusions: Compared to commonly used scoring systems, OASIS is a practical tool and serves as a robust scoring system for assessing mortality in ICU patients diagnosed with sepsis.

Magnesium deficiency is defined as a pathophysiologic factor in numerous illnesses. This study aims to define the effects of magnesium levels on patients in the intensive care unit (ICU) regarding length of stay in the ICU, length of mechanical ventilation (MV), and 28-day mortality. The following data were collected during initial assessment of patients admitted to the ICU with acute respiratory failure (ARF). Demographic data, magnesium and potassium levels, Charlson's Comorbidity Index (CCI), Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) scores, length of MV, length of hospital stay in the ICU, 28-day mortality, and ICU discharge status. In the initial serum analysis prior to treatment of patients in the ICU, the mortality rate of the patient group with hypermagnesemia was found to be statistically significant when compared with other magnesium levels (P = .018). Apart from renal failure, ICU mortality is higher in the hypermagnesemia group than other groups. Hypermagnesemia is an electrolyte abnormality that is generally seen in older individuals and those with serious comorbidity and it can be used in mortality prediction.

Background and Objectives: The predictive value of changes in C-reactive protein (CRP), procalcitonin, and leukocyte levels, which are commonly used in the diagnosis of infection in sepsis and septic shock, remains a topic of debate. The aim of this study was to evaluate the effectiveness of changes in CRP, procalcitonin, and leukocyte counts on the prognosis of 230 patients admitted to the intensive care unit (ICU) with the diagnosis of sepsis and pneumonia-related septic shock between 1 April 2022 and 31 December 2023, and to investigate whether any of these markers have a superior predictive value over the others in forecasting prognosis. Materials and Methods: This single-center, retrospective, cross-sectional observational study included patients who developed sepsis and septic shock due to community-acquired pneumonia and were admitted to the ICU. Demographic data, 1-month and 90-day mortality rates, length of stay in the ICU, discharge to the ward or an outside facility, need for dialysis after sepsis, need for invasive or noninvasive mechanical ventilation during the ICU stay and the duration of this support, whether patients admitted with sepsis or septic shock required inotropic agent support during their stay in the ICU and whether they received monotherapy or combination therapy with antibiotics during their admission to the ICU, the Comorbidity Index score (CCIS), CURB-65 score (confusion, uremia, respiratory rate, BP, age ≥ 65), and Acute Physiology and Chronic Health Evaluation II (APACHE-II) score were analyzed. Additionally, CRP, procalcitonin, and leukocyte levels were recorded, and univariate and multivariate logistic regression analyses were performed to evaluate their effects on 1- and 3-month mortality outcomes. In all statistical analyses, a p-value of <0.05 was accepted as a significant level. Results: According to multivariate logistic regression analysis, low BMI, male gender, and high CCIS, CURB-65, and APACHE-II scores were found to be significantly associated with both 1-month and 3-month mortality (p < 0.05). Although there was no significant relationship between the first-day levels of leukocytes, CRP, and PCT and mortality, their levels on the third day were observed to be at their highest in both the 1-month and 3-month mortality cases (p < 0.05). Additionally, a concurrent increase in any two or all three of CRP, PCT, and leukocyte values was found to be higher in patients with 3-month mortality compared with those who survived (p = 0.004). Conclusions: In patients with pneumoseptic or pneumonia-related septic shock, the persistent elevation and concurrent increase in PCT, CRP, and leukocyte values, along with male gender, advanced age, low BMI, and high CCIS, CURB-65, and APACHE-II scores, were found to be significantly associated with 3-month mortality.

Severity of illness, age, malnutrition, and infection are the important factors determining intensive care unit (ICU) survival. The aim of the study is to determine the relations between Geriatric Nutritional Risk Index (GNRI), C-reactive protein/albumin (CAR), and prognosis-mortality of geriatric patients (age of ≥65 years) admitted to intensive care unit. The study with 10/15/2020, 697 approval date, and number retrospectively registered. Between January 1, 2018 and December 31, 2019, 413 geriatric patients admitted to ICU. The patients were divided into three groups according to their age. The age group, gender, Charlson comorbidity index, intensive care scores (Acute Physiology And Chronic Health Evaluation II and Sequential Organ Failure Assessment), the infection markers (white blood cell, procalcitonin, CAR levels), malnutrition tools for each patient (body mass index, Nutrition Risk in Critically ill score, and GNRI scores) were analyzed retrospectively. Also length of stay (LOS) ICU, length of stay hospital, and 30-day mortality were recorded. Geriatric patients number of 403 was included in the study. Forty-nine (12.3%) patients had a history of malignancy, 272 (67.5%) patients had Chronic Obstructive Pulmonary Disease comorbidity. There was no difference in mortality between age groups. In patients with mortality, body mass index, had being Chronic Obstructive Pulmonary Disease history, GNRI, length of stay hospital, and albumin were significantly lower; malignancy comorbidity rate, inotrope use, modified Nutrition Risk in Critically ill score, mechanical ventilation duration, LOS ICU, Sequential Organ Failure Assessment, Acute Physiology And Chronic Health Evaluation II, Charlson comorbidity index, C-reactive protein, procalcitonin, and CAR were significantly higher. Both malnutrition and infection affect mortality in geriatric patients in intensive care. The GNRI is better than CAR at predicting mortality.

Malnutrition is common in patients diagnosed with chronic obstructive pulmonary disease (COPD). CRP/albumin ratio (CAR) can be used as a parameter to evaluate the inflammatory process and nutritional status together. The aim of this study was to make a general evaluation of the nutritional status of hospitalized patients with COPD and to investigate whether CAR can predict nutritional status in these patients. Patients who were hospitalized with COPD who were consulted to the nutrition department were included in the study. The patients' Nutritional Risk Score-2002 (NRS), demographic data, diagnoses, body mass indexes (BMI), nutritional support applied to the patients were recorded. CRP, Albumin, and CAR values of the patients were determined. Patients recommended nutritional follow-up, total parenteral nutrition (TPN) or enteral nutrition (EN) initiated, and oral nutritional supplement (ONS) support were identified. A total of 393 patients with COPD were analyzed. 88.55% of the patients were in the NRS ≥ 3 risk group. TPN treatment was started in 10.2% of the patients, EN in 10.9%, ONS in 76.3%, and nutritional follow-up was recommended in 2.5% of the patients. While albumin level was lower in patients with NRS ≥ 3, CRP and CAR were higher in patients with NRS ≥ 3 (p < 0.05). There was a negative correlation between NRS-2002 and albumin (p < 0.001). A positive correlation was observed between NRS-2002 and CRP and CAR (p < 0.001). Age and CAR were found to be effective in predicting those with NRS-2002 ≥ 3. The cut-off value for CAR was accepted as 3.26. The need for nutritional support is high in patients hospitalized with COPD. It is important to evaluate nutritional support needs in these patients, regardless of NRS-2002 and BMI. In this respect, the clinician's observation and the decision are as valuable as the scoring that determines malnutrition. We think that the cut-off value of 3.26 determined for CAR can be used in the nutritional risk assessment in patients with COPD.

Background/Aims: To assess the effect of propofol supplemented with alfentanil or fentanyl on cognitive functions for sedation during elective colonoscopy. Materials and Methods: Patients (n=150, 18-65 years old, American Society of Anesthesiologists risk group I-III) scheduled undergo elective colonoscopy were included. They were randomized into three groups using the closed envelope methodpropofol-alfentanil (Group A), propofol-fentanyl (Group F), and propofol only (Group P).Group A patients were given an alfentanil (10 mcg/kg)-supplemented propofol bolus infusion and 5 mcg/kg alfentanil when necessary. Group F patients were given fentanyl (1 mcg/kg)-supplemented propofol and 0.5 mcg/kg fentanyl when necessary. Group P patients were given 1 mg/kg propofol and 0.5 mg/kg propofol when necessary. Vital signs, depth of sedation, recovery parameters, and patient and endoscopist satisfaction were recorded. Trieger dot test (TDT) and Digit Symbol Substitution Test (DSST) were performed post procedure. Results: Demographic data were similar among all patients in the groups. Bispectral index values were lower in Group P (p Conclusions: Compared with propofol-alfentanil and propofol-fentanyl, propofol alone is associated with an increased incidence of apnea, drug consumption, and reported pain. Propofol-alfentanil has a less negative effect on cognitive functions than propofol alone or propofol-fentanyl.
