Objective:To analyze clinical characteristics of patients within 48 hours in pediatric intensive care unit（PICU）,and investigate causes and prognosis of extubation failure in reintubation children.Methods:A single-center retrospective study was conducted.Patients who were reintubated within 48 hours after extubation in PICU at Children's Hospital of Fudan University from January 1，2019 to December 31，2022 were retrospectively enrolled.Patients with unplanned extubation for various reasons which include re-intubation due to surgery and replacement of tracheal intubation were excluded.We analyzed the clinical characteristics，causes of extubation failure and prognosis.Main outcome measures included principal diagnosis，pediatric critical illness score（PCIS），the reason of intubation，the glasgow coma scale（GCS），the direct cause of reintubation，aeration time，hospitalization period，outcomes at PICU discharge and whether to extubate successfully.Results:During the study period，a total of 2 652 patients were extubated in PICU,and a total of 87 children were enrolled.Finally，63（72.4%）patients survived at PICU，nine（10.3%）patients died in hospital，and 15（17.2%）patients were discharged automatically.In the survival group，38（60.3%）patients were decannulated and 25（39.7%）patients underwent tracheotomy.The top three principal diagnosis in 87 cases were central nervous system disease[34（39.1%）cases]，lower airway disease[18（20.7%）cases] and sepsis[nine（10.3%）cases].Of the 87 children，28（32.2%）patients were reintubated due to central respiratory failure，21（24.1%）patients were reintubated due to lower airway disease，20（23.0%）patients were reintubated due to upper airway obstruction，14（16.1%）patients were reintubated due to cough weakness and/or swallowing disturbance，and four（4.6%）patients were reintubated for other reasons.In children with mechanical ventilation duration ≥7 days before first extubation，central nervous system diseases were the most common primary diseases，and it accounts for 55.6%.Central respiratory failure was the main direct cause of reintubation，accounting for 40.0%，and more patients(40.0%) had GCS scores＜8 before the first intubation.Compared with the successful decannulation group，the extubation failure group had the higher proportion of children with GCS＜8（32.7% vs.10.5%， P＜0.05），the longer median duration of mechanical ventilation before the first extubation[239（123，349）h vs.68.5（19，206）h， P＜0.05]and the longer median length of ICU stay[38（23，54）d vs.24（12，43）d， P＜0.05].After comparing the three groups including survival group，in-hospital death group and automatic discharge group，the PCIS score of the survival group was the highest，and the in-hospital death group was the lowest( P＜0.05). Conclusion:The rate of reintubation at 48 h after extubation in PICU is 3.3%.The immediate causes of reintubation mainly included central respiratory failure，lower airway disease，upper airway obstruction，cough weakness and/or dysphagia.The mortality rate of reintubation in critically ill children is high and the prognosis is poor.

Objective@#Scavenger receptor class B type I (SR-BI) is primarily known for its role in the selective uptake of cholesteryl esters (CEs) from high-density lipoproteins (HDLs). Here we investigated whether SR-BI deficiency is associated with other potentially relevant changes in the plasma lipidome than the established effect of HDL-cholesterol elevation. @*Methods@#Targeted ultra-high-performance liquid chromatography-tandem mass spectrometry was utilized to measure lipid species in plasma from female wild-type and SRBI knockout mice. @*Results@#SR-BI deficiency was associated with a reduction in the average CE fatty acid length (−2%; p9-fold rise (p<0.001) in Cer (d18:1/24:1) concentrations. @*Conclusion@#We have shown that SR-BI deficiency in mice not only impacts the CE concentrations, length, and saturation index within the plasma compartment, but is also associated with plasma accumulation of several Cer and SM species that may contribute to the development of specific hematological and metabolic (disease) phenotypes previously detected in SR-BI knockout mice.

ObjectiveTo determine the trend in diabetes-related death and probability of premature mortality among residents in Yangpu District of Shanghai and provide evidence for the formulation of relevant intervention strategies. MethodsMortality and demographic data were collected among residents in Yangpu District of Shanghai from 2002 to 2020. Statistical analysis was conducted using chi-square test with SPSS 21.0 and Excel 2010. Joinpoint regression was used to determine annual percent change （APC）. The mortality was standardized by utilizing the world standard population in 2000. ResultsA total of 25 091 cases of diabetes-related deaths were reported in Yangpu District， Shanghai from 2002 to 2020. The average annual crude mortality of diabetes-related diseases was 122.10/105， which was 116.13/105 in males and 128.23/105 in females. The difference between males and females in crude mortality was statistically significant （P<0.05）. Moreover， primary causes of diabetes-related deaths were diabetes， cardiovascular and cerebrovascular diseases， and tumors. Among diabetic deaths， peripheral circulatory complications accounted for 50.79%， followed by renal complications （16.05%）. The crude mortality in males， females， and total of diabetes-related diseases showed an upward trend， while the standardized mortality remained stable with an upward trend in male and a downward trend in female. Furthermore， the crude mortality in males， females， and total of diabetes complicated with cardiovascular and cerebrovascular diseases showed an increasing trend. In contrast， both the standardized mortality in males and in total showed an increasing trend， while that in females remained stable. The overall crude mortality of diabetes was on the rise， which was increasing in males and stable in females. The overall standard mortality of diabetes was on the decline， which was increasing in males while declining in females. In addition， the probability of premature mortality caused by diabetes-related diseases， cardiovascular and cerebrovascular diseases complicated with diabetes， and diabetes decreased from 2002 to 2020 with no statistical significance. Males showed an upward trend while females showed a downward trend. ConclusionThe mortality of diabetes-related diseases， cardiovascular and cerebrovascular diseases complicated with diabetes， and diabetes among residents in Yangpu District of Shanghai is on the rise. Similarly， standardized mortality and probability of premature mortality in males for all three diseases are also on the rise. It warrants more attention to the health of male diabetes patients and targeted measures to reduce the disease burden.

Objective:To dynamically monitor the pediatric sequential organ failure assessment(pSOFA) score of children in PICU at different time points, and to evaluate the predictive value of pSOFA score for the prognosis of children with sepsis.Methods:A multicenter prospective observational study was conducted to collect the data of children with sepsis admitted to the PICU of four children′s hospitals in Shanghai from December 2018 to December 2019(Children′s Hospital of Fudan University, Shanghai Children′s Medical Center Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai Children′s Hospital Affiliated to Shanghai Jiaotong University School of Medicine, and Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine). We collected their pSOFA scores on the 1st, 3rd, and 7th day after sepsis diagnosis and the highest score.The patients were divided into survival group and death group according to the clinical outcomes at the time of leaving PICU.The clinical characteristics of two groups were compared.Receiver operating characteristic(ROC) curve were used to assess the resolution of the pSOFA score.Logistic regression was used to analyze the relationship between pSOFA score and sepsis mortality.Results:A total of 170 cases diagnosed sepsis were included, with a median age of 32.5(11.5, 83.2) months, and a median length of stay in PICU of 10(6, 21) days.Forty-two died and 128 survived.The medians of the 1st, 3rd, 7th day and the highest pSOFA score of the children in death group[10(7, 12) points, 9(5, 10) points, 7(4, 10) points, 11(7, 12) points, respectively] were higher than those in survival group[4(2, 8) points, 3(1, 6) points, 2(0, 5) points, 6(3, 8) points, respectively]( P<0.05). The area under the ROC curve of the pSOFA score predicting death on day 1 after sepsis diagnosis was greater than that on days 3, 7 and the highest pSOFA score[0.84(95% CI 0.79-0.91) vs.0.80(95% CI 0.71-0.89), 0.77(95% CI 0.65-0.89), 0.83(95% CI 0.77-0.90)], but the difference was not statistically significant( χ2=1.660, P=0.646). The pSOFA score on the first day of diagnosis had the best cut-off value of >6 points for predicting the risk of death from sepsis, with a sensitivity of 97.6% and a specificity of 53.9%.Logistic regression analysis of pSOFA score and childhood sepsis death showed that the OR values corresponding to the 1st, 3rd, 7th day of diagnosis and the highest pSOFA score were 1.58(95% CI 1.350-1.840), 1.39(95% CI 1.218-1.595), 1.38(95% CI 1.184-1.617) and 1.55(95% CI 1.333-1.800), respectively(all P<0.05). The 1-point increase in pSOFA score on the first day of diagnosis of sepsis was associated with a 58% increase in the hazard ratio for death, and each 1-point increase in the highest pSOFA score was associated with a 55% increase in the hazard ratio for death. Conclusion:The 1st, 3rd, 7th day of sepsis diagnosis and the highest pSOFA score could better predict the mortality risk of sepsis in children.Dynamic monitoring of the pSOFA score at different time points has a certain clinical value in predicting the progression and prognosis of children with sepsis.

Objective:To explore the effects of external diaphragm electrical stimulation on the diaphragm thickness and function in mechanically ventilated children.Methods:A randomized controlled trial was conducted in children who were admitted to PICU at Children′s Hospital of Fudan University and received mechanical ventilation between June 2021 and April 2022.The control group was given the routine treatment of mechanical ventilation, and the intervention group was given external diaphragm electrical stimulation in the early stage of mechanical ventilation in addition to routine treatment.Diaphragm thickness was continuously measured by bedside ultrasound every day for one week after mechanical ventilation, and the changing trend of diaphragm thickness was observed, and the diaphragmatic thickening fraction (DTf) and the incidence of ventilator-induced diaphragmtic dysfunction(VIDD) were calculated at the same time.Results:A total of 32 valid samples were included, including 15 cases in intervention group (10 males) and 17 cases in control group (11 males). The median age of the patients was 33 (10, 77) months, and the median duration of mechanical ventilation was 12 (8, 21) days.The reasons for mechanical ventilation in children included respiratory insufficiency in ten cases, brain dysfunction in ten cases, heart failure in eight cases, and postoperative surgery in four cases.The diaphragm end-expiratory thickness (DTe) in intervention group and the control group showed a gradually decreasing trend from the 1st day to the 7th day.The left thickness was reduced by 11% on the 7th day compared to 1st day in intervention group, which was reduced by 18% in control group; the average daily DTe was reduced by 2% per day in intervention group and by 3% per day in control group.The trends on the right and left were similar.The DTe thickness in the intervention group was greater than that in control group, among which, the mean DTe thickness in the left side of the intervention group on the 7th day was (0.110 7±0.023 7)cm, which was greater than that in control group (0.093 5±0.016 9)cm, and the difference was statistically significant ( t=-2.372, P<0.05); On the second day, the mean DTe thickness on the right side in the intervention group was (0.1267±0.0277) cm, which was greater than that in control group (0.104 7±0.018 1)cm, and the difference was statistically significant ( t=-2.688, P<0.05). DTf in the intervention group was lower than that in control group at 7th day, but the difference was not statistically significant(left DTf: adjusted mean difference was -0.117, P=0.088; right DTf: adjusted mean difference was -0.065, P=0.277). The incidence of VIDD in the intervention group was lower than that in control group(33.3% vs.41.2%), but the difference was not statistically significant ( χ2=0.005, P=0.946). Conclusion:External diaphragmatic electrical stimulation may be helpful for alleviating diaphragmatic atrophy in mechanically ventilated children.However, whether the improvement of diaphragm atrophy is beneficial to clinical outcome still needs further study.

Objective:To investigate pediatric sepsis-related mortality of pediatric intensive care unit(PICU) and family socioeconomic status in Yangtze River Delta.Methods:A prospective, multicenter observational study was conducted to collect sepsis cases from eight PICUs in Jiangsu, Zhejiang and Shanghai from August 2016 to July 2017.Sepsis cases were divided into normal sepsis group and severe sepsis group.The primary outcome was in-hospital death.Patient data were prospectively collected including age, gender, medical insurance status, long-term residence, source of admission, first-day pediatric sequential organ failure score(pSOFA) score, underlying diseases and socioeconomic characteristics including family education level, family annual economic income.Results:A total of 4, 983 patients admitted in PICUs, of which 651 patients were diagnosed sepsis on admission.The prevalence of sepsis was 13.1% (651/4 983), and overall mortality was 11.7% (76/651). The prevalence of severe sepsis was 28.3% (184/651), and the mortality was 20.1% (37/184). The overall median age was 0.9 years old.The infant group accounted for 50.8%, including 331 cases, followed by toddler group 19.8% (129 cases), preschool group 13.0% (86 cases), school group 11.8% (77 cases), and adolescent group 4.3% (28 cases). The median pSOFA score was 4.Logistic regression analysis showed that the OR value was 1.4(95% CI 1.3-1.5) of pSOFA score corresponding to the death of sepsis in hospital.There were 14.6% patients left hospital in medical insurance group, while 27.4% in non-medical insurance group, and there was significant difference between these two groups.The median of daily cost was 5, 446 RMB, among which the median of daily cost of sever sepsis was 6, 678 RMB.The median of total cost for sepsis was 36, 109 RMB, and that for severe sepsis was 41, 433 RMB. Conclusion:The sepsis-related mortality was high in PICU.The pSOFA score has a certain predictive value for the prognosis of sepsis.The burden of sepsis is still heavy.Compared with medical insurance families, non-medical insurance families have a higher proportion of choosing left hospital.

Objective:To study the correlation between non-contact anterior cruciate ligament (ACL) injury and functional ankle instability (FAI) in young patients.Methods:A retrospective analysis was conducted of the 102 patients with non-contact ACL injury[61 males and 41 females, with an age of (31.9±6.1) years and a Tegner activity score of (6.1±1.9) points] who had been treated at Department of Orthopedics, Sun Yat-sen Memorial Hospital from January 2017 to March 2020 (injury group). Another 102 citizens without ACL injury from Guangzhou [56 males and 46 females, with an age of (30.3±7.2) years and a Tegner activity score of (6.0±2.1) points] were recruited as a control group. The Cumberland ankle instability tool (CAIT) and the Ankle Joint Functional Assessment Tool (AJFAT) were used to assess whether the subjects had self-conscious FAI or not. A correlation analysis was conducted using the data collected.Results:The 2 groups were comparable because there were no significant differences between them in general data ( P>0.05). By the CAIT score, the incidence of FAI in the injury group [52.9% (54/102)] was significantly higher than that in the control group [32.4% (33/102)] ( P<0.05); by the AJFAT score, the incidence of FAI in the injury group [59.8% (61/102) ] was significantly higher than that in the control group [39.2% (40/102)] ( P<0.05). Pearson correlation analysis showed that diagnoses of FAI by CAIT and by AJFAT were respectively correlated with ACL injury ( r=-0.159, P=0.023; r=-0.215, P=0.002). Conclusions:The incidence of FAI may be high in patients with ACL injury and there is a correlation between FAI and ACL injury.

Drug‐induced hypersensitivity syndrome is also known as drug reaction with eosinophilia and systemic symptoms which is a rare and serious adverse drug reaction. The clinical manifestations include skin eruption,hematologic abnormalities,lymphadenopathy,and internal organ involvement ( liver,kidney, lung) . Its pathogenesis is still unclear and is considered to be related to a variety of factors,including drug‐specific immune responses,viral reactivation and inheritance. Prompt withdrawal of suspicious drugs is the key to treatment,and the use of systemic corticosteroids and intravenous immunoglobulins remains contro‐versial.

Objective@#To compare the clinical effects of autologous semitendinosus tendon and allogenic tendon arthroscopic anatomical reconstruction of anterior talofibular ligament (ATFL) combined with calcaneofibular ligament (CFL) in the treatment of chronic lateral ankle instability.@*Methods@#A retrospective analysis was made of 55 patients with chronic lateral ankle instability who underwent arthroscopic reconstruction of ATFL combined with CFL from January 2012 to June 2017. A total of 28 cases were treated with autologous semitendinosus tendon (autologous group), including 19 males and 9 females, with an average age of 28.5±8.03 years (range, 16-46 years). A total of 27 cases were treated with allogenic tendon (allogenic group), including 17 males and 10 females, with an average age of 27.48±7.89 years (range, 16-46 years). ATFL/CFL was reconstructed by the same method in both groups. The reconstruction methods were the same between the groups. The talus and calcaneus were fixed with absorbable compression nails.@*Results@#The operation duration in the autologous group was 94.07±7.83 min, which was longer than that in the allogeneic group 63.56±7.96 min (t=14.51, P<0.001). Fever days 5.26±0.90 days in allogeneic group were longer than 2.46±0.74 days in autologous group (t=-12.55, P<0.001). Wound healing duration in allogeneic group was 13.44±3.33 days longer than that in autologous group 10.32±2.34 days (t=-4.01, P<0.001). In the autologous group, 28 cases were followed up for 34.54±16.04 months, and 27 cases in the allograft group were followed up for 42.74±17.79 months. The mean AOFAS score improved from 63.64±11.20 before operation to 90.21±4.48 after operation in the autologous group, and that improved from 63.93±10.59 before operation to 89.56±5.15 after operation in the allogeneic group with no significant difference between the two groups after operation (t=0.506, P=0.615). The mean VAS score decreased from 5.79±1.79 before operation to 1.54±1.35 after operation in the autologous group, and from 5.89±1.78 before operation to 2.04±1.32 after operation in the allogeneic group. There was no significant difference between the two groups after operation (t=-1.396, P=0.168). Tegner score increased from 4.07±1.39 to 6.43±1.14 in the autologous group and from 3.85±1.06 to 6.52±0.85 in the allogeneic group with no significant difference between the two groups after operation (t=-0.333, P=0.740). Stress radiographic showed that the talar tilt angle decreased from 15.60°±3.86° to 6.01°±2.64° in the autologous group, 16.99°±3.78° to 7.14°±3.34° in the allogeneic group, and there was no significant difference between the two groups after operation (t=-1.382, P=0.171). Anterior talar displacement reduced from 10.82±3.12 mm to 4.03±1.69 mm in the autologous group, from 10.10±2.02 mm to 4.17±1.52 mm in the allogeneic group, and there was no significant difference between the two groups after operation (t=-0.326, P=0.746). No donor tendon dysfunction was found in the autologous group. At the end of follow-up, there was no difference in ankle dorsiflexion, plantar flexion and hind foot mobility between autologous group and allogeneic group.@*Conclusion@#Arthroscopic autologous tendon and allogeneic tendon reconstruction of AFTL combined with CFL can obtain satisfactory short-term results. The autologous tendon group was superior to the allogeneic group in terms of fever, wound healing time. However, there was no significant difference in clinical effects between the two groups.

Objective To evaluate the clinical results of arthroscopic anatomical reconstruction of anterior talofibular ligament and calcaneofibular ligament for treatment of chronic ankle instability. Methods From June 2012 to August 2016, 27 patients with chronic ankle instability (28 ankles) were treated with arthroscopic anatomical reconstruction of anterior talofibular ligament and calcaneofibular ligament. All the patients were evaluated preoperatively and at the last follow-up using visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) score. The talar tilt angle and anterior translation were assessed radiographically in pre- and postoperative ankle stress views.Results The operations lasted for 75.8 minutes (from 72 to 104 minutes). The 27 patients received a mean follow-up of 14.8 months (range, from 12 to 25 months). All the wounds healed by the first intention. No neurovascular complications were observed and no patient reported ankle stiffness or pain in motion. On average, the anterior talar trans-lation was reduced from 10.82 ± 3.32 mm preoperatively to 4.03 ± 1.70 mm at the last follow-up, the talar tilt angle decreased from 15.60°± 3.86°to 6.01°± 2.64°, the VAS pain score decreased from 5.79 ± 1.79 to 1.54 ± 1.35, and the AOFAS ankle-hindfoot score improved from 63.64 ± 11.20 to 90.21 ± 4.48. All the above differences were statistically significant (P <0.01). Conclusion Arthroscopic anatomical re-construction of anterior talofibular ligament and calcaneofibular ligament can improve function and stability of the ankle joint effectively, providing a valid option for treatment of chronic ankle instability.

Objective To determine the epidemiology of death in PICU in the past ten years.Meth-ods Retrospective cohort study was conducted in the PICU of Childrne ′s Hosip tal of Fud an University from January2005 to December 2014.Resulst The overall mortality rate of PICU was 8.5%overa 10-year peri-od for m January 2005 toD ecember 2014.Compared wti h the period from 2005 to 2009,the mortalti y rate in PICU decreasedf rom 9.7%to 8.0%during ht e period of 2010 to 2014.A totalo f 736 patients died over a 10-year pre iod,including 329(44.7%) infants,191(26.0%) toddlers,118(16.0%) preschoolers,and 98 (13.3%) school-age and adolsec ence.From 2005 to 2009,there were 269 deaths,of which 65.4% were infants and toddlers.From 2010 to 2014,there were 467 deaths,of which 73.7% were infants and toddlers. Among the diseases causing death,the severe pneumonia was the most common disease(21.6%),followed by malignant tumors ( 16.3%) , sepsis ( 15.4%) , accidental injury ( 13.7%) , and severe encephla itis (8.0%).In different age groups,the distribution of the diseases causing death was different,such as infants mainly with sevre e pneum onia(34.3%),t oddlers mainly with accidental injury(16.8%),preschoolers main-ly with accidental injury and malignant tumors(23.7%),school-age and adolescence mainly with malignant tumor(28.6%).From 2005 to 2009,77.5%deaths were critically and very critically ill patients,and the sep sis was the most common cause of death ( 27.6%) especially in very critically ill patients.From 2010 to 2014,83.0%deaths were critically and very critically ill patients,and the accidental injury was the most com-mon cause of death( 23.2%) especially in very critically ill patients, followed by sepsis ( 17.9%).There were 345 deaths ( 46.9%) occurred within the first week of admission, mainly with accidental injury (20.9%).There we re 391 deaths(53.1%) with the PICU stay for 7 or more days,and severe pneumonia (24.3%) was the most common cause of death.Modes of death were categorized as failed cardiopulmonary resuscitation(54.6%) adn forgoing life-sustaining treatme nt(45.4 %).Conclu sion Compared with the pe-riod from 2005 to 2009,the mortality rate in PICU decreaseds gi nificantly during the periodo f 2010 to 2014. The younger the patine t,the higher the mortality rate.Most deaths were attributed to severe pneumonia,fol-lowed by malignant tumors and sepsis.The causes of death also had relations with severity of diseases and lne gth of PICU stay.Failed cardiopulmonary resuscitation and forgoing life-sustaining treatment were still the mostc ommon mode of deaths.
