It is marked by progressive hypoxemia and respiratory distress. Due to the diverse causes of ARDS, the unclear pathogenesis, and the absence of effective predictive markers or biomarkers, there are no effective treatment measures available, resulting in a high mortality rate. ARDS is increasingly recognized for its heterogeneity, biomarkers, and the emergence of new opportunities for the development of diagnostic tools and personalized treatment strategies provided by omics technologies. A single omics analysis cannot fully reveal the heterogeneity and complexity of ARDS, while multi-omics analysis can provide a more systematic and comprehensive understanding of ARDS. Using clinical samples is closer to the actual disease situation compared to animal models. Multi-omics studies based on clinical samples have achieved significant progress in elucidating the pathophysiology of ARDS, identifying ARDS subtypes, and identifying biomarkers related to ARDS. This review focuses on the current applications of genomics, transcriptomics, metabolomics, and proteomics analyses based on clinical samples in the ARDS field, with a focus on the application of these omics methods in ARDS heterogeneity, potential biomarkers, and pathogenesis.

The patients with SA-AKI undergoing first CRRT admitted to the critical care medicine department of General Hospital of Ningxia Medical University from August 2022 to October 2023 were enrolled as the study objects, and they were divided into observation group and control group by random number table method. All patients received routine treatment including anti-infection, optimized volume management and organ function support. On this basis, the observation group was treated with oXiris filter for CRRT, while the control group was treated with ordinary filter for CRRT, and the first treatment time was ≥ 36 hours. General data of the two groups were collected and compared. At the same time, the inflammatory indicators [high-sensitivity C-reactive protein (hs-CRP), procalcitonin (PCT), interleukin-6 (IL-6)], sequential organ failure assessment (SOFA) score, mean arterial pressure (MAP), blood lactic acid (Lac), noradrenaline dosage and other related indicators were collected before CRRT treatment and 24 hours and 48 hours after treatment, and the 7-day and 28-day mortality of patients were recorded.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Finally, 65 patients were enrolled, including 30 in the observation group and 35 in the control group.

It can lead to multiple organ failure, of which the heart is one of the target organs. Fluid resuscitation plays an important role in the treatment of septic shock, but when a patient develops septic-induced cardiomyopathy, the circulation is often not improved by fluid resuscitation, and may even lead to deterioration of circulation. On October 2, 2023, a 52-year-old female patient with septic shock was admitted to the department of intensive care medicine of Civil Aviation General Hospital, whose circulation deteriorated during fluid resuscitation. The main complaint of the patient was left face numbness for more than 20 days, aggravated with unconsciousness for 5 days. Upon admission, the patient was in a coma and intubated by oral tube. The blood pressure was 128/82 mmHg (1 mmHg ≈ 0.133 kPa; intravenous pump of norepinephrine 0.2 μg×kg&lt;sup&gt;-1&lt;/sup&gt;×min&lt;sup&gt;-1&lt;/sup&gt;). Chest CT indicated lung infection, and infection markers were elevated. The main diagnoses were septic shock, pneumonia, acute cerebral infarction of left pontine arm and etc. At 12 hours after admission, according to arterial and central vein blood gas analyses, the oxygen uptake rate was 31% (&gt; 30%), and the veno-arterial blood partial pressure of carbon dioxide (Pv-aCO&lt;sub&gt;2&lt;/sub&gt;) was 7 mmHg (&gt; 6 mmHg), blood lactic acid (Lac) increased, combined with the width of the inferior vena cava of 1.0-1.6 cm, also indicated a relative insufficiency of effective circulating blood volume, so appropriate fluid resuscitation was given. After fluid resuscitation, the urine volume of the patient increased from 40 mL/h to 100 mL/h, but the blood pressure did not increase significantly, indicating that there was no volume responsiveness, so dobutamine 3 μg×kg&lt;sup&gt;-1&lt;/sup&gt;×min&lt;sup&gt;-1&lt;/sup&gt; was added to enhance myocardial contractility. The heart rate did not increase significantly, and the blood pressure was relatively stable. At 21 hours after admission, the patient's systolic blood pressure (SBP) suddenly dropped from 110-120 mmHg to 60-70 mmHg, while heart rate dropped from 100-110 bpm to 80-90 bpm. Therefore, the dosage of norepinephrine was increased to 2 μg×kg&lt;sup&gt;-1&lt;/sup&gt;×min&lt;sup&gt;-1&lt;/sup&gt;, and the dosage of dobutamine was increased to 10 μg×kg&lt;sup&gt;-1&lt;/sup&gt;×min&lt;sup&gt;-1&lt;/sup&gt;, but the circulation could not be maintained. In addition, no tension pneumothorax was found in the chest radiography, and blood routine did not indicate the possibility of acute blood loss. Troponin I (TnI) decreased from 3 778.8 ng/L to 2 025.9 ng/L, brain natriuretic peptide (BNP) increased from 15 ng/L to 1 638 ng/L.

Physiological mechanical stretching is beneficial for maintaining the lineage homeostasis and normal physiological functions of AEC cells, while excessive mechanical stretching can cause damage to AEC cells. Damage to AEC cells is an important aspect in the occurrence and development of VILI. Understanding the effects of mechanical stretching on AEC cells is crucial for developing safe and effective MV strategies, preventing the occurrence of VILI, and improving the clinical prognosis of VILI patients.

The clinical data of sepsis patients admitted to intensive care unit (ICU) of the First Affiliated Hospital of Wenzhou Medical University from September 2021 to September 2023 were collected, including basic information, clinical characteristics, and clinical outcomes. The patients were divided into non-elderly group (age ≥ 65 years old) and elderly group (age &lt; 65 years old) based on age. Additionally, the elderly patients were divided into survival group and death group based on their 30-day survival status. The clinical characteristics of elderly patients with sepsis were analyzed. Univariate and multivariate Logistic regression analyses were used to screen the independent risk factors for 30-day death in elderly patients with sepsis, and the regression equation was constructed.

ICU-acquired weakness (ICU-AW) refers to a group of syndromes with systemic and symmetrical muscle weakness during the intensive care unit (ICU) hospitalization and cannot be explained by the patient's own disease, which often involve diaphragm and skeletal muscle, resulting in difficulty in weaning and nosocomial infection. The incidence of ICU-AW in sepsis patients is over 50%, making it an important factor affecting the prognosis of these patients. The occurrence of sepsis ICU-AW is related to many factors, which can be summarized into two categories, including sepsis-related factors such as sepsis-associated inflammatory response, sepsis-associated encephalopathy (SAE), and treatment-related factors such as physical immobilization and insufficient nutritional support. The current ICU-AW risk assessment tools are mainly on subjective assessment scales, but there are some limitations in clinical application, and objective assessment tools including predictive model and imaging assessment, which are still in the research stage. \"ABCDEF bundle strategy\" is an important measure to prevent ICU-AW, in which early rehabilitation is the core element. This review of the literature from the risk factors, risk assessment and early rehabilitation of ICU-AW, and focuses on the timing, content, method and safety assessment of early rehabilitation, aims to improve the understanding of ICU-AW, strengthen the prevention of sepsis with ICU-AW, and improve the prognosis of sepsis patients, not only survive, but also live better.</p>","PeriodicalId":24079,"journal":{"name":"Zhonghua wei zhong bing ji jiu yi xue","volume":"37 1","pages":"87-91"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143450241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
