ABSTRACT
Objective:To investigate the correlation of lung ultrasound score and poor prognosis in internal shock patients in intensive care unit (ICU).Methods:The clinical data of 200 shock patients admitted to the ICU of Wuzhou Red Cross Hospital from July 2019 to June 2021 were selected for study. According to the prognosis of patients, they were divided into survival group and death group. The clinical data of shock patients in ICU with different prognosis were analyzed by single factor analysis, multiple factor regression analysis and predictive value analysis.Results:All patients were followed up. The end point of the study was death or transfer from ICU. The follow-up period was 28 days, with a median of 16 days. The 28-day survival rate (OS) of all patients was 62.5%(125/200). The Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, prothrombin time (PT), Fbg, D-dimer(D-D), lactic acid, oxygenation index and lung ultrasound score of the patients in the survival group and the death group were significantly different (all P<0.05), while other indexes were not significantly different (all P>0.05). The results of COX multivariate analysis showed that APACHE Ⅱ score, lactate, and lung ultrasound score were independent prognostic factors of shock patients in ICU (all P<0.05). The survival curves of patients with different lung ultrasound scores were significantly different ( P<0.05). The higher the lung ultrasound score, the lower the 28-day survival rate ( P<0.05). The receiver operating characteristic(ROC) curve analysis showed that the area under curve (AUC), sensitivity and specificity of predicting the prognosis of patients with lung ultrasound score were 0.753, 76.0% and 71.2%, respectively; The AUC , sensitivity and specificity of APACHE Ⅱ score were 0.774, 77.3% and 79.2% respectively; The AUC, sensitivity and specificity of lactic acid were 0.783, 81.3% and 68.8% respectively, with no significant difference (all P>0.05). Conclusions:The lung ultrasound score , lactic acid and APACHE Ⅱ scores are independent risk factors affecting the prognosis of ICU shock patients, and have considerable predictive value.
ABSTRACT
Objective:To investigate the correlation between lung ultrasound score at the end of spontaneous breathing trial (SBT) and cumulative fluid balance at 48 h and their predictive value of extubation outcome in patients with intro-abdominal infection (IAI) under mechanical ventilation.Methods:A retrospective study was conducted. Patients with IAI under mechanical ventilation for more than 48 h were collected from three hospitals from October 1, 2017 to September 30, 2018. Routine demographic variables and clinical characteristics were recorded. The patients were divided into the successful extubation group and failed extubation group according to whether they could maintain spontaneous breathing for 48 h after extubation. LUS at the end of SBT (before extubation) and cumulative fluid balance at 48 h were compared between the two groups. LUS and cumulative fluid balance at 48 h were analyzed by bivariate correlation analysis, and their correlations with shallow fast breathing index (RSBI) and precursor protein of BNP (Pro-BNP) were analyzed. The predictive value of LUS at the end of SBT (before extubation) and cumulative fluid balance for extubation failure were analyzed by receiver operating characteristic curve (ROC).Results:Totally 207 patients were enrolled. There were significant differences in LUS before extubation [12 (10, 14) vs. 16 (14, 17) points], cumulative fluid balance [-318 (-1 116, 200) mL vs. 1 140 (685, 1 614) mL], RSBI [60 (55, 66) (times/min)/L vs. 70 (65, 78) (times/min)/L], pro-BNP [250 (122, 1 292) pg/mL vs. 1156 (285, 4 346) pg/mL], IAP >15 mmHg [32.8% vs. 46.6%], and ICU stay [8 (6, 12) days vs. 11 (8, 14) days] ( P<0.05). Logistic regression analysis showed that the COPD history, RSBI, LUS at the end of SBT, and cumulative fluid balance at 48 h before extubation were independent risk factors for extubation failure. Correlation analysis showed that LUS was moderately correlated with cumulative fluid balance at 48 h ( r=0.41, P<0.001), weakly correlated with RSBI ( r=0.381, P<0.001), and weakly correlated with pro-BNP ( r=0.220, P<0.001). Cumulative fluid balance at 48 h was weakly correlated with RSBI ( r=0.31, P<0.001), but not with pro-BNP. LUS at the end of SBT and cumulative liquid balance at 48 h had predictive value for extubation failure [AUC=0.87 (95% CI: 0.82-0.91), AUC=0.89 (95% CI: 0.85-0.94), P<0.001]. Conclusions:There is a moderate correlation between LUS at the end of SBT (before extubation) and 48 h cumulative fluid balance in patients with IAI and mechanical ventilation. LUS at the end of SBT (before extubation) and cumulative fluid balance at 48 h have some predictive value for extubation failure.
ABSTRACT
Objective:To investigate the clinical predictive value of combined diaphragmatic and pulmonary ultrasound in acute respiratory failure patients with mechanical ventilation (MV).Methods:From January 2020 to August 2022, patients with acute respiratory failure admitted to People's Hospital Affiliated to Ningbo University who underwent invasive MV and weaning were enrolled. After meeting the weaning standards, spontaneous breathing test (SBT) was performed using T-tube. Right diaphragm excursion (DE), diaphragm thickness and lung ultrasound score (LUS) were collected by bedside ultrasound at 30 minutes of SBT, and rapid shallow respiratory index (RSBI), diaphragmatic-shallow respiratory index (D-RSBI) and diaphragmatic thickening rate (DTF) were calculated. According to the weaning outcome, the patients were divided into successful weaning group and failed weaning group. The clinical data of all patients were collected, and the ultrasound parameters and clinical indicators were compared between the two groups. Receiver operator characteristic curve (ROC curve) was used to evaluate the predictive value of D-RSBI, RSBI, DE combined with LUS score and DTF combined with LUS score for weaning failure patients.Results:A total of 77 patients were enrolled, including 54 cases in the successful weaning group and 23 cases in the failed weaning group. The right DE and DTF of patients in successful weaning group were significantly higher than those in failed weaning group [right DE (cm): 1.28±0.39 vs. 0.88±0.41, DTF: (32.64±18.27)% vs. (26.43±15.23)%, both P < 0.05], LUS score, RSBI and D-RSBI were significantly lower than those in failed weaning group [LUS score: 11.45±2.67 vs. 18.33±3.62, RSBI (times·min -1·L -1): 72.21±19.67 vs. 107.35±21.32, D-RSBI (times·min -1·mm -1): 0.97±0.19 vs. 1.78±0.59, all P < 0.05]. ROC curve analysis showed that when the cut-off value of D-RSBI and RSBI was 1.41 times·min -1·mm -1 and 56.46 times·min -1·L -1, the area under the ROC curve (AUC) for predicting weaning failure was 0.972 and 0.988; and the sensitivity was 95.7% and 87.0%, respectively; the specificity was 81.0% and 100.0%, respectively. The AUC of right DE combined with LUS score and DTF combined with LUS score in predicting weaning failure were 0.974 and 0.985, respectively, with a sensitivity of 91.3% and a specificity of 98.1%. Conclusions:Combined assessment of diaphragmatic and pulmonary ultrasound is a good parameter to effectively predict weaning failure in MV patients, which has high application value in guiding weaning in MV patients, and is worthy of clinical application.
ABSTRACT
Objective:To investigate the correlation between dead space fraction and lung ultrasound score (LUS) and their prognostic value in patients with acute respiratory distress syndrome (ARDS).Methods:The data of 98 patients with ARDS treated in the intensive care unit (ICU) of the First Affiliated Hospital of Jinzhou Medical University from January to December 2020 were collected and analyzed. The gender, age, acute physiology and chronic health evaluationⅡ(APACHEⅡ), oxygenation index, dead space fraction and LUS score immediately and 24, 48, 72 and 96 hours after ICU admission and 28-day outcomes of all patients were collected. Pearson correlation was used to analyze the correlation between dead space fraction and LUS score. Binary Logistic regression was performed to analyze whether the dead space fraction and LUS score could be the risk factors of the prognosis in patients with ARDS. Receiver operator characteristic curve (ROC) was used to analyze the predictive effect of dead space fraction and LUS score on 28-day mortality in patients with ARDS.Results:A total of 98 patients with ARDS were included, of which 76 cases survived and 22 cases died within 28 days. With the prolongation of ICU stay, the dead space fraction and LUS score in the survival group increased first and then decreased. The dead space fraction and LUS score in the death group continued to increase to 96 hours, and were significantly higher than those in the survival group (dead space fraction: 0.569±0.019 vs. 0.491±0.021, LUS score: 20.09±2.39 vs. 15.13±1.91, both P < 0.05). There was a positive correlation between the dead space fraction and LUS score at 48, 72 and 96 hours in ICU ( r values were 0.200, 0.471 and 0.677, all P < 0.05). Binary Logistic regression analysis showed that dead space fraction and LUS score were independent risk factors affecting the prognosis of patients with ARDS [dead space fraction: odds ratio ( OR) was 69.064, 95% confidence interval (95% CI) was 22.680-123.499, P = 0.008; LUS score: OR was 4.790, 95% CI was 1.609-14.261, P = 0.005]. The results of ROC curve analysis showed that the dead space fraction at 48, 72 and 96 hours after ICU admission could be used to predict the 28-day mortality of patients with ARDS, the sensitivity was 59.1%, 90.9% and 95.5%, and the specificity was 89.5%, 80.3% and 98.7%. The area under the curve (AUC) of dead space fraction predicting 28-day mortality was 0.802, 0.952 and 0.998, all P < 0.01. The LUS score of 72 hours and 96 hours in ICU could be used to predict the 28-day mortality of patients with ARDS, the sensitivity was 77.3%, 77.3% and 100.0%, and the specificity was 68.4%, 88.2% and 80.3%, respectively. The AUC of the LUS score to predict the 28-day mortality of patients were 0.935 and 0.959, both P < 0.01. Conclusion:There was significant correlation between dead space fraction and LUS score, both of which were risk factors of 28-day mortality and be used to evaluate the 28-day prognosis of patients with ARDS.
ABSTRACT
Objective:To study the early predictive value of lung ultrasound score for bronchopulmonary dysplasia (BPD) in preterm infants with gestational age ≤32 w.Methods:From the establishment of the databases PubMed, Medline, Embase, Cumulative Index to Nursing and Allied Health (CINAHL), Cochrane Library, CNKI, CQVIP and Wanfang databases to February 17, 2022, studies on BPD with lung ultrasound score were searched. Literatures were screened according to the inclusion and exclusion criteria. The quality of the literature was evaluated and the eligible data were extracted. Stata 15.1 software was used for Meta-analysis.Results:Fourteen studies with a total of 1 645 preterm infants were included. The results showed that the sensitivity of the lung ultrasound score at 7 d of life predicting BPD was 0.71 (95% CI 0.64~0.77), the specificity was 0.83 (95% CI 0.74~0.89), and AUC was 0.81 (95% CI 0.78~0.84). At 14 d, the sensitivity was 0.64 (95% CI 0.59~0.69), the specificity was 0.89 (95% CI 0.72~0.96), and AUC was 0.68 (95% CI 0.64~0.72). Meta-analysis showed that sex, BA and birth weight were not sources of heterogeneity. Conclusions:Meta-analysis shows that lung ultrasound score has predictive value for BPD in preterm infants with GA ≤32 w, especially at 7 d of life. Lung ultrasound score is helpful in clinical decision-making.
ABSTRACT
Objective:To explore the value of 5G robotic remote ultrasound in the diagnosis of plateau pulmonary edema(HAPE).Methods:A total of 27 patients who quickly entered Nagqu, Tibet at an altitude of 4 600 m-5 600 m from March to December 2021 and developed one of the clinical symptoms of HAPE were collected. All patients were examined by 5G remote robotic ultrasound and lung CT respectively. Kappa test was used to analyze the consistency of the two diagnostic results, and McNemar test was used to compare the difference in diagnostic results. The ROC curve was used to analyze the sensitivity and specificity of remote lung ultrasound scores in the diagnosis of HAPE.Results:Among the 27 patients, 16 showed thickening of pleural line, increasing of B line, lung consolidation, pleural effusion, etc. Meanwhile, 11 showed no abnormality. Additionally, 8 cases had diffuse pulmonary fluid in both lungs, and 8 cases had localized pulmonary fluid. ROC curve showed that the area under the curve of lung ultrasound score for the diagnosis of HAPE was 0.947 (95% CI=0.78-0.99, P<0.001). The sensitivity and specificity were 0.933 and 0.917, respectively. Lung CT diagnosis was positive in 15 cases. Lung CT showed thickening of lung texture, ground glass, small nodular shadow, fine reticulate shadow, etc. The diagnostic results of the two techniques were in good agreement (Kappa=0.924, P<0.001), and there was no significant difference between the two methods ( P>0.05). Conclusions:5G remote robotic ultrasound has high consistency with CT in the diagnosis of HAPE and is an alternative early diagnosis method for HAPE. It may have clinical application value in scattered medical resources and remote plateau areas.
ABSTRACT
Objective:To explore the value of bedside lung ultrasound in the early diagnosis and severity assessment of ventilator-associated pneumonia (VAP).Methods:A prospective observational study was conducted in 60 patients with VAP (VAP group) and 62 patients without VAP (control group) who were admitted to department of intensive care unit of General Hospital of Ningxia Medical University from September 2018 to July 2020. The gender, age and underlying diseases of non-VAP group were matched with VAP group. The general clinical data such as gender, age, underlying diseases, department source of the patient, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment (SOFA) score were recorded. The body temperature, white blood cell count (WBC), procalcitonin (PCT), oxygenation index (PaO 2/FiO 2), alveolar artery oxygen differential pressure (P A-aDO 2) were recorded. During mechanical ventilation, the patient's body temperature, WBC, sputum characteristics, and the change of the lung ultrasound were dynamically observed. With or without dynamic air bronchogram, lung ultrasound was considered to be positive as long as there were small subpleural consolidation or tissue-like sign. Ventilator-associated pneumonia lung ultrasound score (VPLUS) and lung ultrasound score (LUSS) were performed, and chest CT scan was completed on the same day. Use positive chest CT scan as the standard to evaluate the diagnostic efficacy of lung ultrasound, VPLUS score, and the combination of the two with PCT for VAP. LUSS was used to assess the severity of disease in patients with VAP. The correlation between LUSS and PaO 2/FiO 2, P A-aDO 2, APACHEⅡscore and SOFA score were analyzed. Results:① General information: compared with non-VAP group, VAP group had more emergency surgery patients [51.7% (31/60) vs. 33.9% (21/62), P = 0.047], APACHEⅡ score and SOFA score were significantly higher (APACHEⅡscore: 15.4±5.7 vs. 13.4±3.4, P = 0.021; SOFA score: 8.8±4.2 vs. 6.3±3.3, P < 0.001), body temperature tended to rise (℃: 38.3±0.8 vs. 38.0±0.9, P = 0.054), more patients had airway purulent secretions [65.0% (39/60) vs. 41.9% (26/62), P = 0.011], and mechanical ventilation time and length of ICU stay were longer [mechanical ventilation time (days): 10.5 (6.6, 15.0) vs. 4.3 (3.0, 6.0), P < 0.001; length of ICU stay (days): 14.8 (9.0, 18.0) vs. 6.0 (4.0, 9.1), P < 0.001], 28-day mortality rate was higher [31.7% (19/60) vs. 9.7% (6/62), P = 0.003].② Diagnostic efficacy evaluation: when lung ultrasound was positive, VPLUS≥3 and PCT > 0.5 μg/L were used separately for the diagnosis of VAP, the sensitivity was 73.3%, 75.0%, 61.7%, respectively; the specificity was 80.6%, 58.1% and 59.7%, respectively; the 95% confidence interval (95% CI) was 0.685-0.842, 0.574-0.748, 0.514-0.694, respectively, all P < 0.05, positive lung ultrasound had good sensitivity and specificity. When positive lung ultrasound or VPLUS≥3 were combined with PCT > 0.5 μg/L for tandem test, the specificity of VAP diagnosis was increased to 95.2% and 83.9%, respectively; but the specificity of VAP diagnosis of positive lung ultrasound combined with PCT > 0.5 μg/L was higher than VPLUS ≥3 combined with PCT > 0.5 μg/L (95.2% vs. 83.9%, P < 0.05).③ Correlation analysis: LUSS showed a significant positive correlation with APACHEⅡ and SOFA score ( r values were 0.407, 0.399, P values were 0.001, 0.002, respectively), LUSS had no relation with PaO 2/FiO 2 and P A-aDO 2 ( r values were 0.189, -0.064, P values were 0.629, 0.149, respectively). Conclusions:Lung ultrasound can early detect VAP , and its diagnostic specificity is significantly improved when combined with PCT > 0.5 μg/L. LUSS is closely related to the severity of disease in VAP patients, therefore, lung ultrasound may be an effective method for early diagnosis and efficacy evaluation of VAP patients.
ABSTRACT
Objective:To evaluate the predictive value of lung ultrasound on mortality in children with severe acute respiratory distress syndrome (ARDS) undergoing extracorporeal membrane oxygenation (ECMO) support.Methods:A prospective observational study was used to enroll patients with severe ARDS who met the Berlin criteria in the Pediatric Intensive Care Unit of Children’s Hospital of Shanghai Jiao Tong University from January 2016 to December 2019. Patients with ECMO support <3 d, lack of appropriate acoustic windows, with severe pneumothorax, and secondary to congenital heart disease or chronic lung disease were excluded. ECMO parameters, respiratory mechanics parameters and outcome were collected and analyzed. Lung ultrasound score (LUS) was measured at the initiation of ECMO as LUS-0 h, then at 24 h, 48 h, 72 h, and 7 d after ECMO support as the value of LUS-24 h, LUS-48 h, LUS-72 h, LUS-7 d, as well as after weaning ECMO as LUS-w. The patients were divided into survivors and non-survivors according to hospital survival status. Receiver operating characteristic (ROC) curve and Kaplan-Meier survival analysis curve were performed to explore the predictive value of lung ultrasound on mortality in patients with severe ARDS undergoing ECMO.Results:A total of 26 patients were enrolled in this study, of which 18 patients survived and 8 died. There were no significant differences in PRISM Ⅲ, dynamic pulmonary compliance (Cdyn), oxygenation index, PaO 2/FiO 2, and PaCO 2 on PICU admission between the two groups (all P>0.05). The values of LUS-72 h and LUS-w in non-survivors were significantly higher than those in survivors [26 (24, 29) vs16 (13, 19), P<0.01] and [30 (26, 35) vs11 (10, 13), P<0.01]. The values of Cdyn-72 h, Cdyn-7 d and Cdyn-w in survivors were significantly higher than those in non-survivors [0.48 (0.42, 0.54)mL/cmH 2O·kg vs 0.36 (0.29, 0.40) mL/cmH 2O·kg, P<0.01; 0.60 (0.52, 0.67) mL/cmH 2O·kg vs 0.27 (0.13, 0.30) mL/cmH 2O·kg, P<0.01, and 0.66 (0.62, 0.70) mL/cmH 2O·kg vs 0.30 (0.13, 0.35) mL/cmH 2O·kg, P<0.01]. ROC curve analysis showed that an area under ROC curve (AUC) of LUS-72 h for predicting PICU mortality was 0.955 (95% CI: 0.864-1.000; P<0.01). The cutoff value of LUS-72 h was 24 with a sensitivity of 87.5% and a specificity of 100.0%. Kaplan-Meier survival analysis showed that PICU mortality of patients with LUS-72 h≥24 was significantly higher than that in patients with LUS-72 h < 24 ( P<0.01) . Conclusions:Lung ultrasound is an effective tool for monitoring progress of children with severe ARDS received ECMO support. LUS-72 h >24 is an index to predict the worsen outcome in children with severe ARDS under ECMO support.
ABSTRACT
Background: The discrimination between benign and malignant adnexal masses is important for clinical management and surgical planning in such patients. Various combined methods of evaluation adnexal mass have also been proposed. Risk of malignancy index (RMI) is a combined parameter which is simple, preclinical and highly sensitive, and more specific. Risk of malignancy index 4 (RMI 4) is calculated as a product of ultrasound score (U)×menopausal score (M)×CA 125×tumor size. Objective of this study was to determine if the RMI (RMI 4) can distinguish between benign and malignant adnexal masses.Methods: A prospective study was conducted on 30 women with an adnexal mass presenting in the OPD and emergency and RMI-4 calculated. Cut off level of 450 was set to differentiate between benign and malignant mass.Results: In this study, the value of RMI-4 is less than 450 in 17 patients with benign disease and 3 patients with malignant disease. The value is more than 450 in 2 patients with benign disease and 8 patients with malignant disease. RMI-4 >450 had a sensitivity of 72.73% and specificity is 89.47%. The positive predictive value is 80% and negative predictive value is 85%. The p-value for RMI-4 in this study is 0.001 which is highly significant.Conclusions: RMI is a reliable, simple, easy to use and cost-effective method in differentiating benign from malignant adnexal masses.

ABSTRACT
Objective@#To investigate the value of mechanical power (MP) to predict the potential of the lung recruitment maneuver and assess prognoses in patients with acute respiratory distress syndrome (ARDS).@*Methods@#Patients with moderate-to-severe ARDS who required mechanical ventilation therapy longer than 24 hours were randomly selected April 2017 to April 2019. The lung recruitment maneuver (RM) protocol was performed according to the patient's condition, their MP, lung ultrasound score (LUS), oxygenation index (P/F), and dead volume ratio (Vd/Vt), which were monitored before the RM and one hour after the RM. The patients were divided into the lung recruitment maneuver potential positive group (RMP-P group) and lung recruitment maneuver potential negative group (RMP-N group) according to whether the variation in the patient's RM aeration score (ΔLUS) was≥5. Differences in MP between the two groups were compared and correlations between MP variation (ΔMP), aeration score variation (ΔLUS), oxygenation index variation (ΔP/F), and dead volume ratio variation (ΔVd/Vt) were analyzed. The receiver operating characteristic curve (ROC) was used to calculate the predictive value of MP for the potential of RM and the prognosis (28-day mortality) of patients with moderate or severe ARDS.@*Results@#Eighty-three patients were enrolled in the study, 45 in the RMP-P group and 38 in the RMP-N group. There was no statistical difference in the baseline levels between the two groups (P>0.05). After RM treatment, MP, LUS scores, and Vd/Vt for each patient in the two groups decreased significantly compared to the pre-RM values, whereas, the P/F increased significantly (P<0.05). The MP, LUS scores, and Vd/Vt in the RMP-P group were significantly lower than those in the RMP-N group (P<0.05), whereas there was no difference in the P/F between the two groups after RM treatment (P>0.05). The ΔMP, ΔLUS, and ΔVd/Vt in the RMP-P group were significantly higher than those in the RMP-N group (P<0.05). There was no difference in the ΔP/F between the two groups (P>0.05). There was a significant positive correlation between ΔMP and ΔLUS and ΔVd/Vt in all patients (r=0.4746, 0.3995, P<0.01) and no significant correlation withΔP/F (r=0.0314, P>0.05). The area under the ROC curves of ΔMP for predicting the potential of RM was 0.856, with a sensitivity of 91.1% and a specificity of 63.2%. The AUC of the 28-day survival status was 0.788, with a sensitivity of 84.3% and a specificity of 62.5% (P<0.05).@*Conclusions@#Mechanical power monitoring before and after RM can be used to predict the potential of the lung recruitment maneuver and assess the prognosis in patients with moderate-to-severe ARDS.
ABSTRACT
Objective: To explore the application value of 7-joint ultrasound score in the treat-to-target of rheumatoid arthritis. Methods Totally 40 patients with rheumatoid arthritis in active stage were enrolled. The changes of disease activity score of 28 joints (DAS28), synovitis, tenosynovitis and 7-joint ultrasound score before and after treatment were analyzed in accordance with the principles of clinical standard treatment, and the correlation of changes of synovitis, tenosynovitis, 7-joint ultrasound score and changes of DAS28 were analyzed. Results: Compared with those before treatment, DAS28, synovitis, tenosynovitis and 7-joint ultrasound score decreased significantly after escalation therapy (all P<0.001), but changes in bone erosion were not statistically significant (P=0.317). The changes of synovitis, tenosynovitis, 7-joint ultrasound score and DAS28 showed relatively weak correlation (rs=0.363, 0.318, 0.317, P=0.021, 0.045, 0.047). Conclusion: 7-joint ultrasound score can be used to detect changes of disease activity of rheumatoid arthritis, but not yet be advocated as testing index for treat-to-target escalation.
ABSTRACT
Objective: To explore the clinical significance of 7-joint ultrasound score (US7) method in evaluating the progression of RA. Methods Totally 198 RA patients were divided into 3 groups according to disease activity score of 28 joints (DAS28), i.e. light active period group (n=55), medium active period group (n=83) and heavy active period group (n=60). Gray-scale ultrasound (GSUS) and power Doppler ultrasound (PDUS) were performed on the severe lateral wrist joints, the second/third metacarpophalangeal joints, proximal interphalangeal joints and the second/fifth metatarsophalangeal joints. US7 scoring was performed. The differences among 3 groups were compared, and their correlation with the severity of the disease were analyzed. Logistic regression analysis was performed to find the predictive factor of RA. Results: With the severity of disease, DAS28, GSUS synovitis, PDUS synovitis, GSUS tendon tenosynovitis, PDUS tendon tenosynovitis, US7 total score showed significant increase (all P<0.001). There were positive correlation of GSUS synovitis, PDUS synovitis, GSUS tendon tenosynovitis, PDUS tendon tendonitis, US7 total score to the severity of RA (all P<0.001). PDUS synovitis in US7 scoring system was an independent predictor of light-medium activity. PDUS synovitis and GSUS tendon tenosynovitis were independent predictors of medium-heavy activity (all P<0.001). Conclusion: There is correlation between the progression of US7 and RA. PDUS synovitis is an efficient indicator for identifying the severity of RA.
ABSTRACT
Objective To investigate the value of mechanical power(MP)to predict the potential of the lung recruitment maneuver and assess prognoses in patients with acute respiratory distress syndrome(ARDS).Methods Patients with moderate-to-severe ARDS who required mechanical ventilation therapy longer than 24 hours were randomly selected April 2017 to April 2019.The lung recruitment maneuver(RM)protocol was performed according to the patient's condition,their MP,lung ultrasound score(LUS),oxygenation index(PIF),and dead volume ratio(Vd/Vt),which were monitored before the RM and one hour after the RM.The patients were divided into the lung recruitment maneuver potential positive group(RMP-P group)and lung recruitment maneuver potential negative group(RMP-N group)according to whether the variation in the patient's RM aeration score(ΔLUS)was ≥ 5.Differences in MP between the two groups were compared and correlations between MP variation(Δ MP),aeration score variation(Δ LUS),oxygenation index variation(Δ P/F),and dead volume ratio variation(Δ V d/Vt)were analyzed.The receiver operating characteristic curve(ROC)was used to calculate the predictive value of MP for the potential of RM and the prognosis(28-day mortality)of patients with moderate or severe ARDS.Results Eighty-three patients were enrolled in the study,45 in the RMP-P group and 38 in the RMP-N group.There was no statistical difference in the baseline levels between the two groups(P＞0.05).After RM treatment,MP,LUS scores,and Vd/Vt for each patient in the two groups decreased significantly compared to the pre-RM values,whereas,the P/F increased significantly(P＜0.05).The MP,LUS scores,and Vd/Vt in the RMP-P group were significantly lower than those in the RMP-N group(P＜0.05),whereas there was no difference in the PIF between the two groups after RM treatment(P＞0.05).The Δ MP,Δ LUS,and Δ V d/Vt in the RMP-P group were significantly higher than those in the RMP-N group(P＜0.05).There was no difference in the Δ P/F between the two groups(P＞0.05).There was a significant positive correlation between Δ MP and Δ LUS and Δ Vd/Vt in all patients(r=0.4746,0.3995,P＜0.01)and no significant correlation with Δ P/F(r=0.0314,P＞0.05).The area under the ROC curves of Δ MP for predicting the potential of RM was 0.856,with a sensitivity of 91.1％and a specificity of 63.2％.The AUC of the 28-day survival status was 0.788,with a sensitivity of 84.3％and a specificity of 62.5％(P＜0.05).Conclusions Mechanical power monitoring before and after RM can be used to predict the potential of the lung recruitment maneuver and assess the prognosis in patients with moderate-to-severe ARDS.
ABSTRACT
Objective To investigate the clinical correlations between mechanical power (MP) and lung ultrasound score (LUS), and analyze their evaluation value of prognosis in patients with acute respiratory distress syndrome (ARDS). Methods Patients with moderate to severe ARDS, who underwent invasive mechanical ventilation admitted to intensive care unit (ICU) of the Lianyungang Affiliated Hospital of Xuzhou Medical University from January 2017 to March 2019 were enrolled. The MP and LUS were recorded 0, 24, 48 and 72 hours after ICU admission. The patients were divided into death group and survival group according to the 28-day prognosis. The trends of MP and LUS in the two groups and their differences between groups were analyzed. Then the MP and LUS were analyzed by bivariate correlation analysis, and their correlations with acute physiology and chronic health evaluationⅡ (APACHEⅡ), sequential organ failure assessment (SOFA), oxygenation index (PaO2/FiO2), and blood lactate (Lac) were also analyzed. The predictive value of MP and LUS 0 hour and 72 hours in ICU for 28-day mortality in patients with moderate to severe ARDS was analyzed by receiver operating characteristic (ROC) curve. Results At the end, 83 patients were enrolled, with 32 died and 51 survived in 28-day. The Lac level, APACHEⅡ and SOFA in the death group were significantly higher than those in the survival group, while PaO2/FiO2 was significantly lower than the survival group, and the other baseline indicators were not statistically significant between the two groups. As the treatment time increased, the MP and LUS of the survival group showed a significant decrease trend, while the death group showed a significant upward trend. The MP and LUS of the death group 0, 24, 48, 72 hours after ICU admission were significantly higher than those of the survival group [MP (J/min): 20.97±3.34 vs. 17.20±4.71, 21.56±3.48 vs. 16.87±3.85, 22.72±2.97 vs. 16.13±3.52, 25.81±3.46 vs. 15.24±3.78; LUS: 19.17±3.31 vs. 16.27±4.28, 20.28±3.65 vs. 15.27±3.23, 21.53±4.32 vs. 13.63±3.71, 23.94±3.82 vs. 12.53±2.94, all P < 0.05]. There was a significant positive correlation between MP and LUS 0, 24, 48, 72 hours after ICU admission (r value was 0.547, 0.577, 0.754, and 0.783, respectively, all P < 0.01). The MP and LUS at 0 hour of ICU admission were significantly positively correlated with SOFA and PaO2/FiO2 (r value was 0.421, 0.450, and 0.409, 0.536, respectively, all P < 0.01), but no correlation with Lac and APACHEⅡ was found. The ROC curve analysis showed that the MP and LUS at 0 hour and 72 hours had predictive value for the 28-day mortality [the area under the ROC curve (AUC) of MP was 0.836, 0.867; and the AUC of LUS was 0.820, 0.891, all P < 0.01]. Conclusions There was a significant correlation between MP and LUS in patients with moderate to severe ARDS. The MP and LUS could be used early to evaluate the 28-day prognosis of patients with moderate to severe ARDS.

ABSTRACT
Objective@#To explore the predicting performance of renal resistive index (RRI), semi quantitative power Doppler ultrasound (PDU) score and serum cystatin C (Cys C) for acute kidney injury (AKI) in patients with cardiac failure or sepsis.@*Methods@#A prospective, observational study was conducted. Critically ill patients with acute cardiac failure or sepsis admitted to the emergency intensive care unit (ICU) of Cangzhou Central Hospital from January 1st to December 31st in 2018 were enrolled. In addition to the demographic data, serum Cys C, RRI, and PDU score were measured within 6 hours after admission to ICU. Renal function was assessed on day 5 according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Patients who proceeded to AKI stage 2 or 3 within 5 days from admission were defined as the AKI 2-3 group; other patients were classified into the AKI 0-1 group. The differences of each index were compared in all patients, cardiac failure patients and sepsis patients between the two groups. Multivariate binary Logistic regression was carried out to identify the independent risk predictors of AKI 2-3. Receiver operator characteristic (ROC) curves were plotted to examine the values of Cys C, RRI, PDU score, and RRI+PDU in predicting AKI 2-3.@*Results@#Thirty-seven patients with cardiac failure (11 with no AKI, 10 with AKI stage 1, 3 with AKI stage 2, and 13 with AKI stage 3) and 26 patients with sepsis (8 with no AKI, 2 with AKI stage 1, 7 with AKI stage 2, and 9 with AKI stage 3) were recruited. In all patients as well as the subgroup of cardiac failure, compared with the AKI 0-1 group, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment (SOFA) score, rate of continuous renal replacement therapy (CRRT), 28-day mortality, serum creatinine (SCr), Cys C and RRI were higher in AKI 2-3 group, and urine output, PDU score were lower; in the subgroup of sepsis, rate of CRRT, SCr, and Cys C were higher in AKI 2-3 group, and urine output was lower. Multivariate Logistic regression analysis found that Cys C and PDU score were independent risk factors for AKI 2-3 in all patients [Cys C: odds ratio (OR) = 11.294, 95% confidence interval (95%CI) was 2.801-45.541, P = 0.001; PDU score: OR = 0.187, 95%CI was 0.056-0.627, P = 0.007]; RRI and PDU score were independent risk factors for AKI 2-3 in patients with cardiac failure [RRI (×10): OR = 6.172, 95%CI was 0.883-43.153, P = 0.067; PDU score: OR = 0.063, 95%CI was 0.007-0.584, P = 0.015]; Cys C was the independent risk factor for AKI 2-3 in patients with sepsis (OR = 22.830, 95%CI was 1.345-387.623, P = 0.030). It was shown by ROC curve analysis that: in the subgroup of cardiac failure, the predictive values of RRI, PDU score and Cys C were well [area under the curve (AUC) and 95%CI was 0.839 (0.673-0.942), 0.894 (0.749-0.971), 0.777 (0.610-0.897), all P < 0.01]. RRI+PDU performed best in predicting AKI (AUC = 0.956, 95%CI was 0.825-0.997, P < 0.01), and the predictive value was higher than Cys C [AUC (95%CI): 0.956 (0.825-0.997) vs. 0.777 (0.610-0.897), P = 0.034]. In the subgroup of sepsis, the predictive value of Cys C was well (AUC = 0.913, 95%CI was 0.735-0.987, P < 0.01), however, the predictive value of RRI, PDU, RRI+PDU were poor.@*Conclusions@#RRI and PDU score effectively predict AKI stage 2 or 3 in cardiac failure patients, but not in patients with sepsis. The predictive values of Cys C for AKI are similar in patients with cardiac failure or sepsis.
