Objective:To evaluate the safety and efficacy of secondary transport on extracorporeal membrane oxygenation (ECMO) for critically ill children.Methods:This was a retrospective cohort study. Data from 222 pediatric patients who underwent ECMO transport from May 2019 to May 2024 at 5 ECMO centers and Chinese Database of Pediatric Extracorporeal Life Support Organization were collected. The cases were divided into primary and secondary transport groups by nature of transport. The clinical data, including demographics, ECMO indications, transport distance, pre-transport lab results, prognosis and complications were analyzed. Two independent samples t-test, Wilcoxon test, and χ2 test or Fisher′s exact probability method were used to compare the differences between 2 groups and evaluate the safety and efficacy of secondary transport. Results:Among the 222 children transported with ECMO, there were 135 males and 87 females, with an age of 3.0 (0.2, 7.0) years. There were 202 cases in the primary transport group and 20 cases in the secondary transport group. All secondary transport patients had failed attempts at weaning ECMO before transfer. The patients in the secondary transport group were older, had higher rates of surgical cannulation, circulatory support, and pre-ECMO lactate levels compared to the primary transport group (7.0 (2.8, 10.0) vs. 3.0 (0.2, 6.0) years old, 55.0% (11/20) vs. 3.6% (7/202), 80.0% (16/20) vs. 41.6% (84/202), (10±4) vs. (7±6) mmol/L, Z=3.41, χ 2=66.31, 10.99, t=2.24, all P<0.05). In the secondary transport group, the vasoactive-inotropic scores of patients on circulatory support and the oxygenation index for patients requiring respiratory support were higher than those in the primary transport group (83±33 vs. 82±68, 51.0±1.8 vs. 37.4±10.2, t=2.36, 2.63, respectively; both P<0.05). There were no statistically significant differences between the 2 groups in sex, transport distance, pre-ECMO creatinine, arterial blood gas BE values, and ECMO duration (all P>0.05). No life-threatening complications occurred during the transport in either group. Two patients in the secondary transport group underwent heart transplantation, and 1 patient underwent radiofrequency ablation. The overall survival rate between the 2 groups showed no statistically significant difference (45.0% (9/20) vs. 55.4% (112/202), χ2=1.15, P>0.05). Conclusions:Secondary ECMO transport for critically ill children don't increase mortality or life-threatening complications during transport. ECMO patients who cannot receive effective treatment locally can benefit from secondary transport to an advanced ECMO center provides further treatment opportunities.

OBJECTIVE To explore the relationship between peripheral blood interferon γ(IFN-γ)/interleukin-4(IL-4)and the short-term prognosis of children with Mycoplasma pneumoniae pneumonia(MPP),and to analyze the influencing factors for the short-term prognosis of children with MPP.METHODS A total of 170 children with MPP admitted to the hospital from Jan.2021 to Jan.2024 were selected(MPP group).Based on the condition 28 days after treatment,they were divided into a poor prognosis group(n=49)and a good prognosis group(n=121).Clinical data of the children were collected,and the levels of peripheral blood interleukin-4(IL-4)and inter-feron-γ(IFN-γ)were measured to calculate the IFN-γ/IL-4 ratio.Multivariate Logistic regression model was used to analyze the factors affecting the short-term prognosis of children with MPP.RESULTS In the poor prognosis group,the duration of antibiotic use,the proportion of pleural effusion,the proportion of extrapulmonary compli-cations,and the levels of peripheral blood IL-4 and IFN-γ were higher than those in the good prognosis group,while the IFN-γ/IL-4 ratio was lower than that in the good prognosis group(P＜0.05).Logistic regression re-sults showed that persistent fever,prolonged antibiotic use and the occurrence of extrapulmonary complications were risk factors for the short-term prognosis of children with MPP(P＜0.05),and a high IFN-γ/IL-4 ratio was a protective factor(P＜0.05).CONCLUSION Persistent fever,prolonged antibiotic use and extrapulmonary com-plications are risk factors for the short-term prognosis of children with MPP,and high IFN-γ/IL-4 values is a pro-tective factor.

Objective:To investigate the characteristics and management approaches of patients admitted to the isolation wards in public general hospitals under regular epidemic prevention and control measures of coronavirus disease 2019 (COVID-19).Methods:All patients admitted to the isolation ward in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from May 14, 2020 to April 15, 2021 were enrolled, and the general information, illness severity, preliminary diagnosis and transfer department of the patients were analyzed.Results:Out of the 2 292 patients admitted to the isolation ward, critical patients accounted for 34.34% (787 cases), surgical system patients accounted for 80.06% (1 835 cases) and internal medicine system patients accounted for 19.94% (457 cases), fever patients accounted for 11.30% (259 cases). All patients successfully completed COVID-19 screening, and no COVID-19 patients were detected. Among the total enrolled patients, 2 201 patients were promptly transferred to the corresponding departments for further treatment, with an average transfer time of 0.55 day. The remaining 91 patients were discharged from the isolation ward with an average hospitalization stay of 1.27 days.Notably, there were no COVID-19 cross-infection occurred between patients and medical staff in the isolation ward.Conclusions:Scientific and efficient management of isolation wards ensure timely screening and effective treatment for patients, and simultaneously achieving "zero" infection for both medical staff and patients.

Objective:To explore the effect of pediatric critical illness score (PCIS), pediatric risk of mortality Ⅲ score (PRISM Ⅲ), pediatric logistic organ dysfunction 2 (PELOD-2), pediatric sequential organ failure assessment (p-SOFA) score and Glasglow coma scale (GCS) in the prognosis evaluation of septic-associated encephalopathy (SAE).Methods:The data of children with SAE admitted to the Pediatric Intensive Care Unit (PICU), Guangdong Provincial People’s Hospital, Guangdong Academy of Medical Sciences from January 2010 to December 2020 were retrospectively analyzed. They were divided into the survival and death groups according to the clinical outcome on the 28th day after admission. The efficiency of PCIS, PRISM Ⅲ, PELOD-2, p-SOFA and GCS scores for predicting death were evaluated by the area under the ROC curve (AUC). The Hosmer-Lemeshow goodness-of-fit test assessed the calibration of each scoring system.Results:Up to 28 d after admission, 72 of 82 children with SAE survived and 10 died, with a mortality rate of 12.20%. Compared with the survival group, the death group had significantly lower GCS [7 (3, 12) vs. 12 (8, 14)] and PCIS scores [76 (64, 82) vs. 82 (78, 88)], and significantly higher PRISM Ⅲ [14 (12, 17) vs. 7 (3, 12)], PELOD-2 [8 (5, 13) vs. 4 (2, 7)] and p-SOFA scores [11 (5, 12) vs. 6 (3, 9)] ( P<0.05). The AUCs of PCIS, PRISM Ⅲ, PELOD-2, p-SOFA and GCS scores for predicting SAE prognosis were 0.773 ( P=0.012, AUC>0.7), 0.832 ( P=0.02, AUC>0.7), 0.767 ( P=0.014, AUC>0.7), 0.688 ( P=0.084, AUC<0.7), and 0.692 ( P=0.077,AUC<0.7), respectively. Hosmer-Lemeshow goodness-of-fit test showed that PCIS ( χ2=5.329, P=0.722) predicted the mortality and the actual mortality in the best fitting effect, while PRISM Ⅲ ( χ2=12.877, P=0.177), PELOD-2 ( χ2=8.487, P=0.205), p-SOFA ( χ2=9.048, P=0.338) and GCS ( χ2=3.780, P=0.848) had poor fitting effect. Conclusions:The PCIS, PRISM Ⅲ and PELOD-2 scores have good predictive ability assessing the prognosis of children with SAE, while the PCIS score can more accurately evaluate the fitting effect of SAE prognosis prediction.

Objective:To investigate the effect of high-frequency repetitive transcranial magnetic stimulation(rTMS)on cue attention in male patients with alcohol use disorder (AUD) after the acute withdrawal.Methods:A total of 90 male patients AUD who were hospitalized in the Second Affiliated Hospital of Kunming Medical University and Psychiatric Hospital of Yunnan province from May 2020 to December 2020 were enrolled, then they were divided into study group and control group using random number table.Because 18 cases fell out during the study, 36 cases were included in each of the two groups.After the alcohol withdrawal syndrome eliminated, the study group received high-frequency rTMS at 10 Hz for 14 consecutive days, and the control group was administrated by sham rTMS.At baseline and after true or sham rTMS, the cognitive psychology experiment Oddball paradigm was completed, and the behavioral data of the subjects were collected.Paired-sample t-test was used to compare the changes of the two groups before and after treatment.Data analysis were conducted using SPSS 21.0 software. Results:There was no statistical difference between the study group and the control group in terms of drinking level, cognition level and demographic data(all P>0.05). In the Oddball paradigm, compared with the control group((526.72±75.30)ms, (0.98±0.02))the reaction time((497.93±64.51)ms, t=3.145, P=0.008) and accuracy rate((0.99±0.01), t=-2.803, P=0.016) in alcohol-related cues were significantly improved in the study group after rTMS intervention, but in the control group, there were no statistical differences(both P>0.05), whether the cue was alcohol related or not. Conclusion:The results suggest that the rTMS can enhance the attention bias of alcohol-related cues and change the impulse process partly.

Thousands of children experience cardiac arrest in hospital each year, and only about half of them can survive to hospital discharge.Recognizing cardiac arrest in time and initiating high-quality cardiopulmonary resuscitation as early as possible is the key to improve the prognosis.During resuscitation, the longer the duration of cardiopulmonary resuscitation, the lower the survival rate.To prevent the heart rhythm from deteriorating into ventricular fibrillation, pulseless ventricular tachycardia and other malignant rhythms, timely use of adrenaline is beneficial to improve survival.For shockable heart rhythms, the recommended initial dose of defibrillation is 2 J/kg.Invasive airways can be harmful during resuscitation.For qualified medical institutions, choosing appropriate cases to perform extracorporeal cardiopulmonary resuscitation as soon as possible will improve the prognosis.After resuscitation, normal oxygen supply and normal pressure ventilation should be maintained, and physiological monitoring such as arterial diastolic pressure and end-tidal carbon dioxide should be used to guide post-resuscitation management.However, mild hypothermia treatment does not bring benefits to improve the prognosis.Imaging tests such as EEG, CT, and magnetic resonance imaging can assess the prognosis of nerves after resuscitation early, while neuron-specific enolase, S100 calcium binding protein, and somatosensory evoked potential have better predictive value, but lacking of enough clinical data.
