Nutrition determinants of acute skeletal muscle loss in critically ill patients: A prospective observational cohort study.

BACKGROUND: Skeletal muscle loss is associated with adverse outcomes in critically ill patients and risk factors of acute skeletal muscle loss are not well described. This study aims to determine the factors associated with acute skeletal muscle loss in critically ill patients. METHODS: This prospective observational cohort study was conducted with patients who were expected to stay in the intensive care unit (ICU) for at least a week. Rectus femoris cross-sectional area (RFCSA) measurements were performed within 48 h of ICU admission and on study day 7. The percentage change in RFCSA and variables associated with this change were evaluated by univariate and multivariate regression analysis. RESULTS: Over a 12-month period, 518 patients were assessed for eligibility and 44 critically ill patients with a mean age of 59.3 ± 10.9 years were enrolled; 52.3% of them were female. There were significant reductions in RFCSA (16.8 ± 16.5%; P < 0.001). The mean amounts of protein and energy consumed compared with those prescribed were 67.0 ± 28.8% and 71.5 ± 38.3%, respectively. Multivariate regression analysis revealed that frailty was independently associated with acute skeletal muscle loss after adjusting for confounding factors in our cohort of patients. CONCLUSION: Frailty status before ICU admission is associated with acute skeletal muscle loss and may be important for identifying critically ill patients at high risk of muscle wasting.

Neuromuscular Electrical Stimulator as a Protective Treatment against Intensive Care Unit Muscle Wasting in Sepsis/Septic Shock Patients.

OBJECTIVE: To investigate the efficacy of neuromuscular electrical stimulation (NMES) application in preventing muscle wasting in intensive care unit (ICU) patients diagnosed with sepsis/septic shock. STUDY DESIGN: A single-centre, unblinded, parallel-group, prospective, randomised clinical study. PLACE AND DURATION OF STUDY: Ondokuz Mayis University, Faculty of Medicine Hospital, Level 3 ICU, between October 28th 2018, and October 1st, 2020. METHODOLOGY: Eighty patients from a single centre who were diagnosed with sepsis/septic shock, followed up at level 3 ICU, and met the criteria were included. The patients were evaluated in 2 groups: One who received physiotherapy alone (n=40) and the other who received physiotherapy + NMES (n=40). The development of intensive care unit-muscle wasting was evaluated in patients of both groups. Muscle wasting was identified by anthropometric and ultrasonographic measurements. The day the patients were diagnosed with sepsis was determined as the first day and the bilateral anthropometric and ultrasonographic measurements of the biceps brachii and rectus femoris muscles were obtained on days 3, 7, 14, 21, and 28. RESULTS: There was no significant difference between the groups in the ultrasonographic and anthropometric measurements on days 1, 3, and 7 (p>0.005). However, the ultrasonographic measurements of the group that received physiotherapy + NMES demonstrated a significantly lower loss in the upper extremities on days 14 and 21 compared to the group that received physiotherapy alone (p=0.003 and p=0.028, respectively). No significant difference was found in the anthropometric measurements. CONCLUSION: The NMES, which have been increasingly used as new treatment protocols in the prevention of ICU-AW, yield favourable results in patients with sepsis/septic shock.

Effect of tocilizumab on intensive care patients with Covid-19 pneumonia, a retrospective cohort study.

BACKGROUND: In this study, the efficacy of an IL-6 antagonist, Tocilizumab, administered in the early period was studied in intensive care patients with COVID-19 pneumonia followed by hypoxic and systemic inflammation not receiving mechanical ventilation support. METHODS: Patients with COVID-19 pneumonia who have signs of hypoxia and systemic inflammation and/or who have acute bilateral infiltrates on chest radiograph and who received tocilizumab treatment were compared with the patients who received standard medical therapy. Patients who were followed up with COVID-19 pneumonia and respiratory failure between March 2020 and March 2021 were retrospectively evaluated in the study. A 400 mg - 800 mg iv dose (depending on weight) of Tocilizumab was administered. The primary endpoint was determined as intensive care unit mortality. RESULTS: A total of 213 patients who were admitted with respiratory failure associated with COVID-19 to our third-level intensive care unit were evaluated. Of these patients, the study was conducted with 50 patients in the tocilizumab treatment group and 92 patients in the standard treatment group. During the intensive care period, 26 patients (28.3%) in the standard treatment group and 12 patients (24%) in the group receiving tocilizumab died. The adjusted hazard ratio for mortality in the tocilizumab group was 0.39 (95% confidence interval [CI], 0.186 to 0.808; p = 0.001 by log-rank test). During the intensive care period, 22 patients (24.8%) in the standart treatment group and 16 patients (32%) in the tocilizumab group were intubated. The adjusted hazard ratio for a primary outcome intubation in the tocilizumab group was 0.71 (95% confidence interval [CI], 0.355 to 1.424; p = 0.184 by log-rank test).

Timeline of critically ill 2019 SARS-CoV-2 cases after onset of illness: Intensive care data from Turkey.

Introduction: This study aimed to evaluate the epidemiological, clinical, laboratory characteristics and treatment and clinical outcomes of severe COVID19 cases from a 3rd degree intensive care unit in Turkey. Materials and Methods: The study was conducted in a level three, 16-bed COVID intensive care unit. The investigation was planned as a retrospective and observational study. Patients who were admitted with COVID-19 pneumonia and respiratory failure in the intensive care unit between March 2020 and March 2021 and followed up due to critical illness were evaluated. Result: A total of 213 patients that were admitted to the intensive care unit with the diagnosis of COVID-19 pneumonia were included in the study. Median age of the patients was 66 (IQR 56.5-74) years, and 134 (62.9%) were males. One hundred and sixty-six (77.9%) of the patients had at least one comorbidity. Patients were followed up mainly with invasive mechanical ventilation [104 (48.8%)] and high flow nasal cannula [67 (31.5%)]. Median number of days was 7 (IQR 4-10) and included the first symptom onset to intensive care admission. The time to intubation was 9 (IQR 4-15) days, and the median day to intensive care discharge was 16 (IQR 11-23). After the symptoms started, first tocilizumab 9 (IQR 5-11) and pulse steroid treatment 8 (IQR 3-11) were found to be close to each other. In total, 95 (44.6%) of the 213 patients died. Conclusions: SARS-CoV-2 associated viral disease can progress after simple symptoms to hospital admission in a median of four days and to intensive care admission requiring intubation in a median of nine days. We believe that a better understanding of the clinical course of COVID-19 and its change between centers can be revealed through sharing information from different countries and centers.

Extracorporeal membrane oxygenation experiences during COVID-19 pandemic, third wave with younger patients: A retrospective observational study.

OBJECTIVES: In this article, the results of severe coronavirus disease 2019 (COVID-19) cases followed with extracorporeal membrane oxygenation (ECMO) support in a 3-month period in the third wave when there were an increased number of cases of young patients in our intensive care unit (ICU) were presented. METHODS: The study was carried out with all COVID-19 patients who were given ECMO support in our tertiary referral hospital ICU after obtaining the consent of the Ministry of Health Scientific Research Platform and after the approval of the local ethics committee. Patient data were obtained retrospectively from intensive care bedside follow-up charts and computer records. The demographic and clinical characteristics of the patients were presented in average, median, and percentages. The data of the patients were evaluated and compared with the current literature. RESULTS: ECMO treatment was applied in seven patients who were followed up with severe COVID-19 pneumonia in the last 3 months. Venovenous extracorporeal membrane oxygenation (VV-ECMO) was applied to all patients. Five (71.5%) of seven patients were weaned from ECMO. Four (57.2%) of seven patients were discharged from the ICU and hospital in good health. While two of the patients had a cesarean section (C/S) before ECMO, one patient underwent C/S under ECMO. All three newborns were delivered via C/S and all were premature (C/S dates were 35 weeks, 32 weeks, and 27 weeks), and all were discharged from the hospital in good health. CONCLUSION: Our experience shows that ECMO in COVID-19 patients is a lifesaving treatment option that can be successfully applied in severe acute respiratory distress syndrome cases who do not respond to conventional treatments.

The effect of preemptive airway pressure release ventilation on patients with high risk for acute respiratory distress syndrome: a randomized controlled trial.

BACKGROUND AND OBJECTIVES: The objective of this study was to investigate the use of early APRV mode as a lung protective strategy compared to conventional methods with regard to ARDS development. METHODS: The study was designed as a randomized, non-blinded, single-center, superiority trial with two parallel groups and a primary endpoint of ARDS development. Patients under invasive mechanical ventilation who were not diagnosed with ARDS and had Lung Injury Prediction Score greater than 7 were included in the study. The patients were assigned to APRV and P-SIMV + PS mode groups. RESULTS: Patients were treated with P-SIMV+PS or APRV mode; 33 (50.8%) and 32 (49.2%), respectively. The P/F ratio values were higher in the APRV group on day 3 (p = 0.032). The fraction of inspired oxygen value was lower in the APRV group at day 7 (p = 0.011).While 5 of the 33 patients (15.2%) in the P-SIMV+PS group developed ARDS, one out of the 32 patients (3.1%) in the APRV group developed ARDS during follow-up (p = 0.197). The groups didn't differ in terms of vasopressor/inotrope requirement, successful extubation rates, and/or mortality rates (p = 1.000, p = 0.911, p = 0.705, respectively). Duration of intensive care unit stay was 8 (2-11) days in the APRV group and 13 (8-81) days in the P-SIMV+PS group (p = 0.019). CONCLUSIONS: The APRV mode can be used safely in selected groups of surgical and medical patients while preserving spontaneous respiration to a make benefit of its lung-protective effects. In comparison to the conventional mode, it is associated with improved oxygenation, higher mean airway pressures, and shorter intensive care unit stay. However, it does not reduce the sedation requirement, ARDS development, or mortality.

Effects of personality traits on severity of sepsis.

INTRODUCTION: The aim of this study was to reveal the effect of the individual's lifestyle and personality traits on the disease process in patients with sepsis and to have clinical predictions about these patients. MATERIALS AND METHODS: The study was planned as a multi-center, prospective, observational study after obtaining the approval of the local ethics committee. Patients were hospitalized in different intensive care units. Besides demographics and personal characteristics of patients, laboratory data, length of hospital and ICU stay, and mortality was recorded. Two hundred and fifty-nine patients were followed up in 11 different intensive care units. Mortality rates, morbidities, blood analyses, and personality traits were evaluated as primary outcomes. RESULT: Of the 259 patients followed up, mortality rates were significantly higher in men than in women (p= 0.008). No significant difference was found between the patients' daily activity, tea and coffee consumption, reading habits, smoking habits, blood groups, atopy histories and mortality rates. Examining the personal traits, it was seen that 90 people had A-type personality structure and 51 (56.7%) of them died with higher mortality rate compared to type B (p= 0.038). There was no difference between personalities, in concomitant ARDS occurrence, need for sedation and renal replacement therapies. CONCLUSIONS: Among individuals diagnosed with sepsis/septic shock, mortality increased significantly in patients with A-type personality trait compared to other personality traits. These results showed that personal traits may be useful in predicting the severity of disease and mortality in patients with sepsis/septic shock.

Effects of different lipid emulsions on serum adipokines, inflammatory markers and mortality in critically ill patients with sepsis: A prospective observational cohort study.

BACKGROUND & AIMS: Intravenous lipid emulsions in parenteral nutrition may cause different metabolic responses and immune effects in critically ill patients with sepsis. The aim of this study is to investigate the effects of different lipid emulsions on changes in concentrations of adipokine and cytokine and their relationship with mortality in patients. METHODS: Patients enrolled in this prospective, single-center, observational cohort study, were estimated to require more than ten days of parenteral nutrition. They were treated with soybean oil-based or olive oil-based parenteral lipid emulsions. Adipokine and cytokine concentrations of septic patients were determined at enrollment and ten days after, in accordance with the diagnostic criteria of SEPSIS-3. The concentrations levels were measured in an enzyme-linked immunosorbent assay. Mortality was analyzed using the Kaplan-Meier method and Cox regressions. RESULTS: Over a 25-month period, 145 patients were assessed for eligibility and consequently, 40 patients were analyzed. On admission, both groups had comparable physiological scores, comorbidities, malnutrition risk, anthropometric measurements, metabolic/hematologic biomarkers and concentrations of adipokines and cytokines (p > .05). Serum leptin, resistin, and cytokines (IL-6, IL-10, IL-1ß and TNF-α) decreased significantly in the entire cohort over ten days following sepsis (p < .05). Serum resistin decreased in both olive oil-based and soybean oil-based lipid emulsions groups. Serum adiponectin only decreased in soybean oil-based lipid emulsions group (p < .05). There was association between survival and percentage changes in adiponectin, resistin and visfatin concentrations (log rank test: p < .05). CONCLUSION: Adipokine and cytokine responses are affected by medical nutritional therapy in the sepsis process and adipokines may represent functional prognostic biomarkers in critically ill patients with sepsis.

[Mortality prediction ability of phycians in intensive care units of Turkey (MOPAP)]. / Türkiye'de yogun bakim ünitelerinde hekimin mortaliteyi öngörebilme gücü.

INTRODUCTION: Intensive care physicians are increasingly involved in decision making about the prognosis of intensive care unit ICU patients. With this study; we aimed to evaluate the power of clinician foresight at prediction of mortality in patient at triage to intensive care and patient follow-up. MATERIALS AND METHODS: This study was conducted in ICUs located in various geographical regions of Turkey between January 1, 2017-April 30, 2017.The clinical research was planned as observational, multicenter, cross-sectional. RESULT: A total of 1169 intubated patients were followed in 37 different ICU. At the beginning of the follow-up we asked the physician who will follow the patient in the ICU to give a score for the probability of survival of the patients. Scoring included a total of 6 scores from 0 to 5, with the "0" the worst probability "5" being the best. According to this distribution, only 1 (0.9%) of 113 patients who were given 0 points survived. Three (6.1%) of 49 with the best score of 5 died. Survival rates were significantly different in each score group (r: -0.488; p<0.001). After the combined mortality estimation scores based on the clinical observations of the physicians (0 and 1 point score was combined as non-survive, 4 and 5 score was combined as survived) 320 of the 545 patients were estimated to be dead and 225 were predicted survival. Sensitivity and spesifity of scoring system to predict mortality was 91.56% (95% CI: 87.96-94.37), 76.89% (95% CI: 70.82-82.23) respectively. CONCLUSIONS: In this study, we concluded that the physicians who follow the patients in the ICU can predict the poor prognosis at the time of admission and the high mortality rate. The physician's opinion on mortality estimation should be considered in intensive care mortality scoring in addition to other laboratory and clinical parameters.

Can we predict patients that will not benefit from invasive mechanical ventilation? A novel scoring system in intensive care: the IMV Mortality Prediction Score (IMPRES)

Background/aim: The present study aimed to define the clinical and laboratory criteria for predicting patients that will not benefit from invasive mechanical ventilation (IMV) treatment and determine the prediction of mortality and prognosis of these critical ill patients. Materials and methods: The study was designed as an observational, multicenter, prospective, and cross-sectional clinical study. It was conducted by 75 researchers at 41 centers in intensive care units (ICUs) located in various geographical areas of Turkey. It included a total of 1463 ICU patients who were receiving invasive mechanical ventilation (IMV) treatment. A total of 158 parameters were examined via logistic regression analysis to identify independent risk factors for mortality; using these data, the IMV Mortality Prediction Score (IMPRES) scoring system was developed. Results: The following cut-off scores were used to indicate mortality risk: <2, low risk; 2­5, moderate risk; 5.1­8, high risk; >8, very high risk. There was a 26.8% mortality rate among the 254 patients who had a total IMPRES score of lower than 2. The mortality rate was 93.3% for patients with total IMPRES scores of greater than 8 (P < 0.001). Conclusion: The present study included a large number of patients from various geographical areas of the country who were admitted to various types of ICUs, had diverse diagnoses and comorbidities, were intubated with various indications in either urgent or elective settings, and were followed by physicians from various specialties. Therefore, our data are more general and can be applied to a broader population. This study devised a new scoring system for decision-making for critically ill patients as to whether they need to be intubated or not and presents a rapid and accurate prediction of mortality and prognosis prior to ICU admission using simple clinical data.

Prognostic evaluation of cases with thoracic trauma admitted to the intensive care unit: 10-year clinical outcomes.

BACKGROUND: Multiple traumas are a leading cause of mortality among young adults worldwide. Thoracic trauma causes approximately 25% of all trauma-associated deaths. This study aims to determine the independent prognostic factors of mortality in cases with thoracic trauma (isolated or with accompanying organ injuries) who were admitted to the intensive care unit (ICU). METHODS: We retrospectively reviewed data from patients with thoracic trauma who were admitted to our ICU between 2007 and 2016. After excluding pediatric patients (aged <18 years), the study sample included 564 cases. From the records, we collected the patients' demographical data, comorbid diseases, primary trauma as an indication for ICU admission, other traumas accompanying thoracic trauma, type of thoracic injury, and therapeutic interventions. The study sample was divided into two subsets: survival and non-survival groups. These two groups were compared with regards to first ICU day laboratory results and intensive care scores, mechanical ventilation times, and ICU stay lengths. RESULTS: Of the 8063 patients admitted to the ICU between 2007 and 2016, 616 (7.6%) had thoracic trauma. The median age (min-max) of the 564 patients eligible for this study was 43 (18-87) years. Mortality occurred in 159 (28.1%) cases, while 405 (71.8%) were discharged from the ICU. Multivariate regression analyses were also performed, in which every increment in age was associated with a 1.025-fold increase in the odds of mortality due to thoracic trauma. Additionally, the presence of central nervous system (CNS) trauma was associated with a 2.147-fold increase, and the presence of pulmonary contusion was associated with a 1.752-fold increase. CONCLUSION: Results of this study indicate that advanced age, the presence of pulmonary contusion, and accompanying CNS trauma are independent predictors of mortality in patients with thoracic trauma in the ICU. Our non-invasive approach is further supported by the trauma and injury severity score (TRISS) scoring system, which is one of the latest scoring systems used in trauma cases.

Non-infectious Fever After Acute Spinal Cord Injury in the Intensive Care Unit.

OBJECTIVE: The aim of the present study is to evaluate the frequency, etiology, risk factors and clinical outcomes in acute traumatic SCI patients who develop fever and to evaluate the relationship between fever and mortality. DESIGN: Retrospective data were collected between January 2007 and August 2016 from patients diagnosed with persistent fever from SCI cases observed in the ICU. PARTICIPANTS: Among 5370 intensive care patients, 435 SCI patients were evaluated for the presence of fever. A total of 52 patients meeting the criteria were evaluated. OUTCOME MEASURES: Fever characteristics were evaluated by dividing the patients into two groups: infectious (group-1) and non-infectious (group-2) fever. Demographic and clinical data, ICU and hospital stay, and mortality were evaluated. RESULTS: In the patients with noninfectious fever, mortality was significantly higher compared to the group with infectious fever (P < 0.001). Of 52 acute SCI cases, 25 (48.1%) had neurogenic fever that did not respond to treatment in intensive care follow-up, and 22 (88%) of these patients died. Maximal fever was 39.10 ± 0.64 °C in Group-1 and 40.22 ± 1.10 ° C in Group-2 (P = 0.001). There was a significant difference in the duration of ICU stay and hospital stay between the two groups (P = 0.005, P = 0.001, respectively), while there was no difference in the duration of mechanical ventilation between the groups (P = 0.544). CONCLUSION: This study demonstrates that patients diagnosed with neurogenic fever following SCI had higher average body temperature and higher rates of mortality compared to patients diagnosed with infectious fever.
