Comparison of nutritional risk indices (PNI, GNRI, mNUTRIC) and HALP score in predicting adverse clinical outcomes in older patients staying in an intensive care unit.

Malnutrition among critically ill older patients is a frequent problem in intensive care units (ICUs) and is associated with a higher risk of hospital/ICU length of stay (LOS) and mortality. The aim of this study was to evaluate malnutrition in older patients staying in an ICU using the hemoglobin, albumin, lymphocyte, platelet (HALP) score, modified nutrition risk in the critically Ill (mNUTRIC), prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI) and to determine the consistency between these tools and their association with clinical outcomes. This cross-sectional retrospective, observational, hospital-based study included 153 older patients (≥65 years of age), who were admitted to an internal medicine ICU. Sequential organ failure assessment (SOFA) scores and acute physiology and chronic health evaluation (APACHE) II were used to assess disease severity. Nutritional status was evaluated using mNUTRIC, GNRI, PNI, and HALP scores, and their association with ICU LOS and mortality was evaluated using ROC and regression analyses. The mortality rate of the patients was 43.1%. The risk of malnutrition was higher among non-survivors, with mNUTRIC scores showing a significant difference between the groups. The scores for all indices, except HALP, showed significant differences between the groups. APACHE-II, SOFA, and mNUTRIC were the strongest prognostic indices for ICU mortality, with mNUTRIC having the highest sensitivity and negative predictive value. The HALP score was not associated with ICU LOS or a significant prognostic factor for mortality. All indices except HALP were good indicators of clinical outcomes in the study population including older patients. Prospective studies in larger and specific patient populations are needed to draw a strict conclusion in this subject.

Effect of fosfomycin-induced hypernatremia on patients' hospital stay length and survival.

BACKGROUND AND OBJECTIVE: Hypernatremia is a possible side effect of intravenous fosfomycin. The aim of this study was to investigate the effects of changes in sodium (Na) levels on hospital stay and survival in patients hospitalized in the intensive care unit receiving fosfomycin. SUBJECTS AND METHODS: This study was conducted retrospectively on the files of patients over the age of 60, who were admitted to the Internal Medicine Intensive Care Unit. Plasma sodium levels were observed and documented over a period of 14 days. The patients were divided into two groups (Hypernatremia group Na > 145 mEq/L vs normonatremia group 135-145 mEq/L). In addition, daily sodium changes were noted for 14 days in patients. RESULTS: The mean age of the patients was 75 years. Hospitalization days were longer for hypernatremia patients (31.5 days vs 41 days, p = 0.003). Patients with hypernatremia had an extended duration of stay in the intensive care unit. (21 days vs 31 days p = 0.002). The 1-month survival rate was 61.4% in patients with hypernatremia and 24.9% in patients without hypernatremia (p = 0.004). The absence of hypernatremia increases mortality by 2.09 times (95% CI 1.35-3.23). When discharge and mortality rates were analyzed according to sodium fluctuation, discharged patients exhibited a lower sodium fluctuation (4 min/max (-10/19) vs 6 min/max (-16/32) p < 0.001). CONCLUSION: In conclusion, the strength of our study is that it specifically focuses on the consequences of the sodium fluctuation on patient management and provides results.

The Comparison of Ultrasound and Tomographic Images of Lung Involvement in Critically Ill Patients With COVID-19 Pneumonia: A Prospective Observational Study.

Introduction Computed tomography (CT) has a high sensitivity for diagnosing COVID-19 pneumonia in critically ill patients, but it has significant limitations. Lung ultrasonography (LUS) is an imaging method increasingly used in intensive care units. Our primary aim is to evaluate the relationship between LUS and CT images by scoring a critically ill patient who was previously diagnosed with COVID-19 pneumonia and underwent CT, as well as to determine their relationship with the patient's oxygenation. Methods This was a single-center, prospective observational study. The study included COVID-19 patients (positive reverse transcription polymerase chain reaction, RT-PCR) who were admitted to the intensive care unit between June 2020 and December 2020, whose oxygen saturation (SpO2) was below 92%, and who underwent a chest tomography scan within the last 12 hours. CT findings were scored by the radiologist using the COVID-19 Reporting and Data System (CO-RADS). The intensivist evaluated 12 regions to determine the LUS score. The ratio of the partial pressure of oxygen in the arterial blood to the inspiratory oxygen concentration (PaO2/FiO2) was used to assess the patient's oxygenation. Results The study included 30 patients and found a weak correlation (ICC = 0.45, 95% CI = 0.25-0.65, p < 0.05) between total scores obtained from LUS and CT scans. The correlation between the total LUS score and oxygenation (r = -0.514, p = 0.004) was stronger than that between the CT score and oxygenation (r = -0.400, p = 0.028). The most common sonographic findings were abnormalities in the pleural line, white lung, and subpleural consolidation. On the other hand, the CT images revealed dense ground-glass opacities and consolidation patterns classified as CO-RADS 5. Conclusion A weak correlation was found between LUS and CT scores in critically ill COVID-19 pneumonia patients. Also, as both scores increased, oxygenation was detected to be impaired, and such a correlation is more evident with the LUS score.

The assessment of P-wave dispersion and myocardial repolarization parameters in patients with chronic kidney disease.

OBJECTIVE: The risks of sudden death and cardiac arrhythmia are increased in patients with chronic kidney disease (CKD). Here, we aimed to evaluate the indicators of arrhythmias, such as p-wave dispersion (P-WD), QTc dispersion, Tp-e and Tp-e/QT ratio in patients with CKD stages 3-5 on no renal replacement therapy (RRT). MATERIAL AND METHODS: One-hundred and thirty three patients with CKD stages 3-5 and 32 healthy controls were enrolled into the study. No patients received RRT. QTc dispersion, P-WD and Tp-e interval were measured using electrocardiogram and Tp-e/QT ratio was also calculated. RESULTS: Mean age rates were found similar in patients and controls (60.8 ± 14.2 and 61 ± 12.9 y, p = .937, respectively). Compared patients with controls, P-WD (45.85 ± 12.42 vs. 21.17 ± 6.6 msec, p < .001), QTc-min (366.99 ± 42.31 vs. 387.15 ± 20.5 msec, p < .001), QTc dispersion (71.13 ± 27.95 vs. 41.25 ± 14.55 msec, p < .001), Tp-e maximum (81.04 ± 10.34 vs. 75.49 ± 10.9 msec, p < .001), Tp-e minimum (62.25 ± 7.58 vs. 54.8 ± 6.72 msec, p < .001) and Tp-e/QTc ratio (0.19 ± 0.02 vs. 0.18 ± 0.01, p = .001) were found to be different. QTc-max and Tp-e interval were found to be similar in both groups. CONCLUSION: P-WD and QTc dispersion, Tp-e interval and Tp-e/QTc ratio were found to be increased in with CKD stages 3-5 on no RRT.
