RESUMEN
Objective: Extracorporeal membrane oxygenation (ECMO) is a widely used treatment for circulatory and pulmonary support in newborns and young children. Over the past decade, the number of children successfully treated with ECMO has gradually increased. However, despite an increasing number of survivors, new morbidity and long-term health issues are becoming more prevalent. A better understanding of the pediatric ECMO prognosis contributes to improved treatment and care programs and minimizes the risk of sequelae and dysfunctions. We aimed to determine the incidence of new morbidity, prognoses, and follow-up data of survivors treated with ECMO in pediatric intensive care units (PICU) using the Functional Status Scale (FSS). Methods: We retrospectively collected and analyzed clinical data of patients in the PICU who received ECMO from January 2016 to January 2020. Clinical and functional outcomes were assessed at admission and discharge using the FSS. Twenty-seven patients aged between 1 month and 14 years who received ECMO in the PICU were included. Fifty-two percent were male, and the median age was 36 months (interquartile range, 21-114 months). The patients were admitted for fulminant myocarditis (n = 13), acute respiratory distress syndrome (ARDS) (n = 11), and septic shock (n = 3). Results: This study reviewed a single-center experience using the FSS for ECMO treatment in a PICU. The patients' original conditions included fulminant myocarditis, ARDS, and septic shock. Of the 27 patients who received ECMO, 9 (33%) died, 12 (67%) showed improved condition, and 6 (33%) discontinued treatment and left the hospital. Furthermore, the following adverse events were observed in the survivors who were discharged: nine (50%) cases of lower extremity deep vein thrombosis, seven (39%) jugular vein thrombosis, six (33%) acute kidney injury, five (27%) intracranial hemorrhage and cerebral infarction, and one each of (6% each) pulmonary embolism and peripheral nerve injury. Of the 12 patients who survived through 1 year after discharge, five (42%) recovered completely, whereas seven (58%) showed mild to moderate communication and motor dysfunction. The short-term survival rate and 1-year survival rate of ECMO patients were 67% (18/27) and 44% (12/27), respectively. Additionally, approximately one-third of the patients developed a new morbidity after ECMO treatment (6/18). Conclusions: High mortality and new morbidity were common in patients who received ECMO treatment. New morbidity increased the risk of death and exacerbated the functional state. Follow-up and rehabilitation after discharge are essential to achieve positive outcomes.
RESUMEN
Viral sepsis is an often neglected heterogeneous form of sepsis，which can be caused by a variety of viruses.Infants and young children are at high risk of viral sepsis，which is related to their relatively low immunity.Viral sepsis is different from bacterial infection in terms of pathogenesis，clinical phenotype,and treatment strategy.Effective elimination of virus and immune regulation according to different immune types may be beneficial to improve the prognosis.
RESUMEN
Augmented renal clearance（ARC）can be caused by the disease itself，inflammatory state，or therapeutic interventions，and is often associated with severe infections and trauma.Sepsis is one of the most important diseases with high morbidity and mortality in the world.Current studies suggest that ARC is significantly associated with inadequate antimicrobial therapy concentration in patients with sepsis，increasing the risk of clinical treatment failure.It is important to optimize the drug administration strategy for patients with ARC in sepsis，although the current clinical screening of ARC is not yet perfect.This review summarized the literature on changes in blood concentration of antibiotics and administration strategies in patients with sepsis with ARC，in order to provide appropriate medication and clinical guidance for ARC patients.
RESUMEN
Sepsis-induced thrombocytopenia-associated multiple organ failure（TAMOF）is a severe subtype of sepsis-related organ dysfunctions，which has high mortality and poor prognosis.The main clinical characteristics are thrombocytopenia caused by infection and multiple organ dysfunction.However，the exact molecular mechanism of TAMOF remains unclear.The current studies have shown ADAMTS-13，which is a von Willebrand factor lyase，plays an important role during the disease.Plasma exchange could be a treatment method，but still need more large-scale randomized controlled trials to verify.In the future，von Willebrand factor and ADAMTS-13 could become the therapeutic targets for new drug development.
RESUMEN
Sepsis-associated encephalopathy(SAE) is a diffuse brain dysfunction caused by sepsis.The main clinical manifestations are abnormal mental state, high mortality and poor prognosis.At present, there is no unified diagnostic standard for SAE.The exclusion diagnosis is mainly based on clinical symptoms and signs, combined with laboratory examination and imaging auxiliary examination.Among them, brain magnetic resonance imaging and quantitative electroencephalography can early detect brain dysfunction and predict the prognosis of children, which play an important role in the early diagnosis and prognosis assessment of SAE.Cerebral oxygen monitoring can dynamically reflect the changes of brain function and can be used for long-term monitoring of children with severe brain function injury.SAE is closely associated with poor prognosis, and mortality will increase with the extention of hospitalization.Therefore, early identification of SAE is of great significance to reduce mortality.
RESUMEN
Vancomycin plays an increasingly important role in the treatment of complex infections in severe patients, and it is currently the first choice for the treatment of methicillin-resistant S. aureus infection.The incidence of infectious diseases in children is extremely high, and the disease changes quickly, easy to become severe.With the increase of drug-resistant bacteria, vancomycin is becoming widely used.As a special group, children with severe illness have great individual difference, and the conventional dose application of vancomycin often cannot achieve the ideal treatment effect.Therefore, we need to realize the different circumstances of vancomycin pharmacokinetic changes and routine drug therapy monitoring, namely by measuring the patient with drug exposure, pharmacological markers or pharmacodynamic index design, to timely adjust physical treatment regimen, improve drug efficacy, reduce drug resistance and adverse reactions.
RESUMEN
Sepsis is a heterogeneous disease with a complex pathogenesis and diverse clinical manifestations.Sepsis leads to disruption of biochemical homeostasis, which strongly promotes changes in metabolites in the body.Initial differences in metabolites may predict the severity of the disease, and changes in metabolites over time may useful in assessing treatment response, predicting progression of disease progression or clinical outcomes.This review focused on the studies related to the application of metabolomics strategy in sepsis, which could help to understand the potential value of sepsis metabolomics in the pathogenesis, diagnosis, prognosis and treatment of sepsis.
RESUMEN
Objective:To investigate whether vestibular-evoked myogenic potentials (VEMP) can be used to assess brainstem and its supplementary diagnostic value in patients with early-stage Parkinson′s disease (PD).Methods:A total of 123 patients with early-stage PD (PD group) diagnosed in the Department of Neurology of the Second Affiliated Hospital of Soochow University from January 2019 to January 2022 were consecutively enrolled, and 122 healthy controls (healthy control group) were included. Cervical VEMP (cVEMP) and ocular VEMP (oVEMP) examinations were performed on all subjects. VEMP parameters between the 2 groups were compared, and receiver operating characteristic curve was used to evaluate the auxiliary diagnostic efficacy of VEMP for early-stage PD. Correlations between VEMP parameters and motor and non-motor symptoms such as autonomic dysfunction were analyzed in the PD group using Spearman correlation analysis.Results:Bilateral latencies of cVEMP [left P1 latency (Lp13): 19.0 (16.4, 20.9) ms vs 13.1(12.0, 14.2) ms, Z=-11.18, left N1 latency (Ln23): 27.4 (24.6, 29.9) ms vs 21.2 (19.8, 23.0) ms, Z=-10.14; right P1 latency (Rp13): 18.8 (16.2, 20.9) ms vs 13.0 (11.7, 14.1) ms, Z=-10.84, right N1 latency (Rn23): 27.7 (24.3, 29.7) ms vs 21.1 (19.6, 22.9) ms, Z=-10.50] and bilateral latencies of oVEMP [left N1 latency (Ln10): 12.7 (10.7, 14.4) ms vs 10.4 (9.7, 11.4) ms, Z=-8.02, left P1 latency (Lp15): 16.5 (15.1, 18.3) ms vs 14.5 (13.4, 15.3) ms, Z=-7.96; right N1 latency (Rn10): 12.8 (11.4, 14.0) ms vs 10.5 (9.7, 11.5) ms, Z=-8.85, right P1 latency (Rp15): 16.7 (15.3, 18.3) ms vs 14.4 (13.3, 15.1) ms, Z=-9.39] of the PD group significantly prolonged compared to the healthy control group (all P<0.001). Compared to the healthy control group, the area under the curve (AUC) values of Lp13, Ln23, Rp13 and Rn23 of cVEMP in the PD group were all greater than 0.7, and the AUC values of Lp13 and Rp13 in the PD group were greater than 0.9 (all P<0.001); the AUC values of Ln10, Lp15, Rn10, and Rp15 of oVEMP in the PD group were all greater than 0.7 (all P<0.001). The Rn10-p15 corrected amplitude in PD patients was positively correlated with levodopa equivalent dose ( r=0.21, P=0.020). The Rn10 in PD patients was positively correlated with the Non-Motor Symptoms Questionnaire scores ( r=0.21, P=0.023). The Lp13-n23 corrected amplitude was negatively correlated with the Scale for Outcomes in Parkinson′s Disease-Autonomic scores ( r=-0.20, P=0.023). There was no significant correlation between VEMP parameters and Unified Parkinson′s Disease Rating Scale part Ⅲ score ( P>0.05). Conclusion:VEMP, especially cVEMP, as a non-invasive neuroelectrophysiological index, is an objective marker for brainstem damage and could be used for screening early-stage PD patients.

RESUMEN
Yeast autolysis affects the flavor and quality of beer. The regulation of yeast autolysis is a need for industrial beer production. Previous studies on brewer's yeast autolysis showed that the citric acid cycle-related genes had a great influence on yeast autolysis. To explore the contribution of isocitrate dehydrogenase genes in autolysis, the IDP1 and IDP2 genes were destroyed or overexpressed in typical lager yeast Pilsner. The destruction of IDP1 gene improved the anti-autolytic ability of yeast, and the anti-autolytic index after 96 h autolysis was 8.40, 1.5 times higher than that of the original strain. The destruction of IDP1 gene increased the supply of nicotinamide adenine dinucleotide phosphate (NADPH) and the NADPH/NADP+ ratio was 1.94. After fermentation, intracellular ATP level was 1.8 times higher than that of the original strain, while reactive oxygen species (ROS) was reduced by 10%. The destruction of IDP2 gene resulted in rapid autolysis and a decrease in the supply of NADPH. Anti-autolytic index after 96 h autolysis was 4.03 and the NADPH/NADP+ ratio was 0.89. After fermentation, intracellular ATP level was reduced by 8% compared with original strain, ROS was 1.3 times higher than that of the original strain. The results may help understand the regulation mechanism of citric acid cycle-related genes on yeast autolysis and provide a basis for the selection of excellent yeast with controllable anti-autolytic performance.

Mitophagy is a process whereby cells selectively remove mitochondria through the mechanism of autophagy, which plays an important role in maintaining cellular homeostasis. In order to explore the effect of mitophagy genes on the antioxidant activities of Saccharomyces cerevisiae, mutants with deletion or overexpression of mitophagy genes ATG8, ATG11 and ATG32 were constructed respectively. The results indicated that overexpression of ATG8 and ATG11 genes significantly reduced the intracellular reactive oxygen species (ROS) content upon H2O2 stress for 6 h, which were 61.23% and 46.35% of the initial state, respectively. Notable, overexpression of ATG8 and ATG11 genes significantly increased the mitochondrial membrane potential (MMP) and ATP content, which were helpful to improve the antioxidant activities of the strains. On the other hand, deletion of ATG8, ATG11 and ATG32 caused mitochondrial damage and significantly decreased cell vitality, and caused the imbalance of intracellular ROS. The intracellular ROS content significantly increased to 174.27%, 128.68%, 200.92% of the initial state, respectively, upon H2O2 stress for 6 h. The results showed that ATG8, ATG11 and ATG32 might be potential targets for regulating the antioxidant properties of yeast, providing a new clue for further research.

Objective:To explore the pathological mechanism of SN hyperechogenicity by investigating the characteristics of substantia nigra (SN) hyperechogenicity on transcranial sonography (TCS) and serum iron metabolism parameters in the postural instability gait difficulty and tremor dominant subtypes of Parkinson′s disease (PD), and the correlation between them.Methods:A total of 155 PD patients recruited in Parkinson′s Disease Specialty in the Second Affiliated Hospital of Soochow University from January 2019 to December 2021 were divided into postural instability gait difficulty group( n=95) and tremor dominant group( n=60). Meanwhile, 49 healthy gender- and age-matched healthy individuals who sought for physical examination during the same period were included as the control group. All subjects underwent TCS and blood test, and the echo of SN between the postural instability gait difficulty group and tremor dominant group, serum iron metabolism parameters among the three groups were compared. The postural instability gait difficulty group and tremor dominant group were subdivided into with SN hyperechogenicity (SN+ )subgroup and without SN hyperechogenicity (SN-) subgroup respectively according to TCS results, and the differences in serum iron metabolism parameters between the subgroups were further compared. The association between SN hyperechogenicity and serum iron metabolism parameters of the postural instability gait difficulty group and tremor dominant group were further analyzed. Results:The total area of bilateral SN+ , the area of SN+ on the larger side, and the ratio of the total area of SN+ to the midbrain area (S/M) in postural instability gait difficulty group were larger than those in tremor dominant group (all P<0.001). The value of serum ceruloplasmin and transferrin in both postural instability gait difficulty group and tremor dominant group were lower than those in control group (all P<0.001), and compared with tremor dominant group and control group, the postural instability gait difficulty group had lower serum ferritin(all P<0.01). In both postural instability gait difficulty group and tremor dominant group, serum ceruloplasmin in SN+ subgroup was lower than that in SN-subgroup ( P=0.001, 0.032). Moreover, there was a negative correlation between serum transferrin and the area of SN hyperechogenicity in two subgroups(postural instability gait difficulty group: rs=-0.454, P<0.001; tremor dominant group: rs=-0.494, P<0.001). Conclusions:Compared with the tremor dominant patients, the postural instability gait difficulty patients have larger area of SN hyperechogenicity and lower serum ferritin level. The area of SN hyperechogenicity is significantly negatively correlated with serum transferrin level, indicating that the production of this imaging characteristics is related to iron metabolism.
RESUMEN
Objective:To explore the adjunctive diagnostic value of transcranial sonography (TCS) combined with olfactory test in early Parkinson′s disease (PD) and the clinical value of both in the cognitive function of PD patients.Methods:TCS and olfactory test were performed in 157 early PD patients(PD group) and 157 healthy controls(control group) in the Second Affiliated Hospital of Soochow University from January 2018 to January 2022. The differences in clinical characteristics, TCS, and olfactory test results between the two groups were analyzed. The values of TCS, olfactory test, and their combination in diagnosing early PD were evaluated using clinical diagnosis as the gold standard. The correlations of the midbrain area, the midbrain substantia nigra hyperechoic area, and the third ventricle width in TCS examination with the cognitive score were analyzed in the PD group. According to the olfactory test scores, 157 patients with early PD were divided into two groups: 110 cases of PD with olfactory dysfunction (PD-OD) and 47 cases of PD without olfactory dysfunction (PD-NOD). The differences in clinical scores and TCS results between the two groups were compared.Results:The midbrain substantia nigra hyperechoic area, substantia nigra hyperechoic positivity rate, third ventricle width, and olfactory dysfunction rate were higher in the PD group compared to the control group, while the midbrain area and olfactory test scores were lower than those in the control group (all P<0.001). The sensitivity and the coincidence rate of TCS combined with the olfactory test for early PD diagnosis (90.0%, 77.1%) were higher than those of TCS alone (60.0%, 71.3%) and olfactory test alone (70.1%, 72.3%), but the specificity (63.7%) was lower than that of both alone (82.8% for TCS and 75.2% for olfactory test), (all P<0.001). MoCA score, visual space and executive ability, memory, attention, and language were positively correlated with the area of the midbrain ( rs=0.38, 0.32, 0.27, 0.25, 0.23; all P<0.05) and negatively correlated with the width of the third ventricle ( rs=-0.39, -0.22, -0.39, -0.22, -0.32; all P<0.05), and orientation was negatively correlated only with the width of the third ventricle ( rs=-0.24, P<0.05). The MoCA score of PD-OD group[22(18, 25)] was lower than that of PD-NOD group[24(20, 26)]( P=0.040). Conclusions:The combination of TCS and olfactory test can enhance the sensitivity and diagnostic agreement rate for early PD diagnosis, providing some auxiliary value. The cognitive function of PD patients is positively correlated with the midbrain area and negatively correlated with the width of the third ventricle. The cognitive function of PD patients with olfactory dysfunction is lower than that of PD patients without olfactory dysfunction. TCS and olfactory test may help assess cognitive function in PD patients.
RESUMEN
Objective:To analyze the difference of clinical characteristics and outcomes of infants with moderate and severe pediatric acute respiratory distress syndrome(PARDS)diagnosed according to baseline oxygenation index(OI) in pediatric intensive care unit(PICU).Methods:Second analysis of the data collected from the "Efficacy of pulmonary surfactant (PS) in the treatment of children with moderate and severe ARDS" program.Retrospectively compare of the differences in clinical data such as general condition, underlying diseases, OI, mechanical ventilation, PS administration and outcomes among infants with moderate and severe PARDS divided by baseline OI who admitted to PICUs at 14 participating tertiary hospitals from 2016 to December 2021.Results:Among the 101 cases, 55 cases (54.5%) were moderate and 46 cases (45.5%) were severe PARDS.The proportion of male in the severe group (50.0% vs.72.7%, P=0.019) and the pediatric critical illness score(PCIS)[72 (68, 78) vs.76 (70, 80), P=0.019] were significantly lower than those in the moderate group, while there was no significant difference regarding age, body weight, etiology of PARDS and underlying diseases.The utilization rate of high-frequency ventilator in the severe group was significantly higher than that in the moderate group (34.8% vs.10.9%, P=0.004), but there was no significant difference in PS use, fluid load and pulmonary complications.The 24 h OI improvement (0.26±0.33 vs.0.04±0.34, P=0.001) and the 72 h OI improvement[0.34 (-0.04, 0.62) vs.0.15 (-0.14, 0.42), P=0.029)]in the severe group were significantly better than those in the moderate group, but there was no significant difference regarding mortality, length of hospital stay and intubation duration after diagnosis of PARDS between the two groups. Conclusion:In moderate and severe(divided by baseline OI) PARDS infants with invasive mechanical ventilation, children in severe group have better oxygenation improvement in the early stage after PARDS identified and are more likely to receive high frequency ventilation compared to those in moderate group.Baseline OI can not sensitively distinguish the outcomes and is not an ideal index for PARDS grading of this kind of patient.
RESUMEN
Sepsis caused by bacterial infection is still one of the major causes of death in pediatric intensive care units, and the early and rational use of antibiotics plays a key role in reducing the mortality of sepsis.At present, there are some problems regarding appropriate and excessive use of antibiotics in pediatric intensive care units in China.Therefore, it is of great significance to strengthen the management of the use of antibiotics and avoid inappropriate and excessive use while effectively controlling infection, so as to reduce the occurrence of adverse drug reactions and bacterial drug resistance.
RESUMEN
Objective:To analyze the clinical characteristics, changes of bacterial resistance and death risk factors of children with streptococcus pneumoniae infection, so as to provide reference for clinical diagnosis and treatment.Methods:From January 2012 to December 2019, hospitalized pediatric patients at Shengjing Hospital of China Medical University were selected.Patients with streptococcus pneumoniae positive in bacterial culture in body fluids of various parts (including alveolar lavage fluid, blood, cerebrospinal fluid, external auditory canal secretions, and local abscess drainage fluid) within one week after admission were selected as subjects.The clinical characteristics and changes of bacterial resistance of 146 children with streptococcus pneumoniae infection were retrospectively analyzed, and 141 children were divided into improved group (124 cases) and death group (17 cases) according to the follow-up results, and the risk factors related to death of streptococcus pneumoniae infection were analyzed.Results:(1)A total of 146 children were included, mainly at age of 1 to 3 years (74 cases, 50.68%), and 14 cases had underlying diseases, including congenital malformation, spinal muscular atrophy, epilepsy and so on.(2) There were 76 (52.05%) cases of invasive streptococcus pneumoniae.There were 106 (72.60%) cases of pulmonary infection, 59 (40.41%) cases of sepsis, 42 (28.77%) cases of purulent meningitis, and five cases of local and pelvic abscess.Five cases were discharge from hospital, 17 cases died, and the rest were all improved.Among the dead children, five cases died because of multiple organ failure, ten cases died because of brain failure and two cases died because of severe sepsis.Six deaths were complicated with septic shock.(3) There were 169 streptococcus pneumoniae positive samples, among them 51 (30.18%) blood samples, 39 (23.08%) cerebrospinal fluid samples, 67 (39.64%) alveolar lavage fluid samples, seven (4.14%) pleural fluid samples, and other body fluid culture samples were five strains.(4) The sensitivity rates of vancomycin, linezolid, moxifloxacin and telithromycin to streptococcus pneumoniae were 100.00%, and that for levofloxacin was 98.82%.The resistant rate of erythromycin to streptococcus pneumoniae was 97.01%, and multidrug resistant rate was 85.61%.(5) Previous convulsions, cerebrospinal fluid or positive blood culture, sepsis, meningitis were risk factors for death(all P<0.05). Children in the death group had shorter out-of-hospital course of disease, lower levels of 24-hour hemoglobin, platelets, serum albumin, and higher levels of C-reactive protein and D-dimer (all P<0.05). Logistics multi-factor analysis showed that, low hemoglobin ( OR=0.31, P=0.025), high D-dimer( OR=1.16, P=0.038), septic shock ( OR=27.81, P=0.008), and positive cerebrospinal fluid culture ( OR=6.34, P=0.034) were independent risk factors for death from streptococcus pneumoniae infection. Conclusion:The average age of streptococcus pneumoniae infection is small, the onset of severe infection is rapid, and the fatality rate as well as and the incidence of invasive pneumococcal disease are high.During clinical treatment, the utilization rate of amoxicillin should be appropriately increased, and the application of cephalosporin antibiotics should be reduced.
RESUMEN
Exosomes play important roles in cell communication and information transmission.miRNA-126 carried by mesenchymal stem cells exosomes can reduce inflammatory response and protect vascular endothelium by regulating protein expression, thus blocking or alleviating cardiac dysfunction during septic shock, which is expected to become a new way to treat septic shock cardiac dysfunction.
RESUMEN
Cardiovascular disease is the leading cause of human deaths in the world.Studies have found that non-coding RNA plays an important role in cardiovascular disease.Non-coding RNA is not only a potential specific biomarker for cardiovascular disease diagnosis, but also a therapeutic target for the disease.In this paper, the research progress of the diagnostic value and regulatory role of non-coding RNA in the pathogenesis of cardiovascular disease was reviewed in order to provide new ideas for the diagnosis and treatment of cardiovascular diseases.
RESUMEN
Gastrointestinal symptoms are common nonmotor symptoms of Parkinson′s disease, which are related closely to occurrence and progress of Parkinson′s disease, as well as throughout its whole process. For example, constipation can be an important symptom in prodromal stage of Parkinson′s disease, and gastroparesis would weaken the effect of drug by interfering pharmacokinetics. However, insufficient attention has been paid to the gastrointestinal symptoms of Parkinson′s disease presently, and there are few effective treatments, which compromise the quality of patients′ life greatly. The intervention focus on gut-brain axis, microbiota and gastrointestinal barrier may play a positive role in improving gastrointestinal symptoms and delaying the process of Parkinson′s disease.
