Correlation of B-type Natriuretic Peptide Level with Hemodynamic Parameters and Inflammatory Cytokines in Patients with Gram-negative Sepsis / 中国医学科学院学报

Objective To study the correlation of B-type natriuretic peptide(BNP)level with hemodynamic parameters and inflammatory cytokines in patients with Gram-negative sepsis,and further determine the main factors for the significant increase of BNP level. Methods The prospective study method was applied,and septic patients infected with Gram-negative bacteria from May 2017 to October 2019 were enrolled.The patients were divided into the BNP<2400 ng/L group and the BNP≥2400 ng/L group by taking the average value of BNP as the dividing point.The independent predictors of BNP≥2400 ng/L were analyzed by Logistic regression.Pearson correlation analysis was used to analyze the correlation between BNP and various indicators. Results A total of 106 patients with Gram-negative sepsis were included,among which 60 cases present with higher serum BNP levels than the average of(2398.45 ± 421.45)ng/L.Thus BNP≥2400 ng/L was considered as a significantly increased BNP level.Multiple logistic regression analysis showed that cardiac index(CI)[odds ratio (

Survey of attitudes and behaviors of healthcare professionals on delirium in ICU / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To assess the medical community's awareness and practice regarding delirium in the intensive care unit (ICU).</p><p><b>METHODS</b>One hundred and ten predesigned questionnaires were distributed to ICU practitioners in the affiliated hospitals of Zhejiang University.</p><p><b>RESULTS</b>A total of 105 valid questionnaires were collected. Totally, 55.3% of the clinicians considered that delirium was common in the ICU. Delirium was believed to be a significant or serious problem by 70.5% of respondents, and under-diagnosis was acknowledged by 56.2% of the respondents. The incidence of ICU delirium is even more under-estimated by the pediatric doctors compared with their counterparts in adult ICU (P less than 0.05). Primary disease of the brain (agreed by 82.1% of the respondents) was believed to be the most common risk factor for delirium. None of the ICU professionals screened delirium or used a specific tool for delirium assessment routinely. The vast majority (92.4%) of respondents had little knowledge on the diagnosis and the standard treatment of delirium.</p><p><b>CONCLUSIONS</b>Although delirium is considered as a serious problem by a majority of the surveyed ICU professionals, it is still under-recognized in routine critical care practice. Data from this survey show a disconnection between the perceived significance of delirium and the current practices of monitoring and treatment in ICU in China.</p>

Prospective study on prognosis of infants with neonatal subependymal cysts / 中华儿科杂志

<p><b>OBJECTIVES</b>It is confirmed that most neonatal subependymal cysts (SEC) are closely correlated with intrauterine infection and the short-term prognosis of SEC is not very good. Little information about the long-term prognosis of SEC is available. The purpose of the present study was to explore the short-term and long-term prognosis of neonatal SEC cases via a 6-year follow up.</p><p><b>METHODS</b>Seventy SEC neonates detected by cranial ultrasound between October 1993 and October 1994 were enrolled into SEC group and 70 healthy neonates into control group. Serum antibodies (IgG and IgM) to cytomegalovirus (CMV), toxoplasma and rubella virus and PCR for these pathogens (except for rubella virus) were measured in the two groups. CMV-PCR was also performed for urine specimens. Cranial sonography assessment, physical growth evaluation, Bayley developmental scale or Wyeth developmental scale, brain-stem auditory evoked potential (BAEP) and vision examination were undertaken at 3, 6, 12 months and 6 years in the two groups.</p><p><b>RESULTS</b>The positive rate of CMV-IgM and blood CMV-PCR in SEC group was significantly higher than those of control group (19.1% vs. 5.7%, 12.9% vs. 2.9%). The positive rate of urine CMV-PCR in SEC group was also significantly higher (40% vs 17.1%). No significant difference could be found in the positive rate of PCR for toxoplasma and rubella-IgM between the two groups. The weight and height of infants with SEC were obviously lower than those in control group during the first year after birth. The parameters of the physical development in SEC infants reached the similar level as controls till 6 years old. However, the index of mental development below 80 was more often seen in infants with SEC comparing to that in control group during the whole six years. There were no abnormal findings either in BAEP or vision examination in the two groups.</p><p><b>CONCLUSION</b>Infants with SEC may show a transient retardation of physical growth after birth, while their mental developmental retardation might last for longer time. It is suggested that cranial ultrasound examination should be performed in all neonates for the detection of SEC, and a longer follow-up should be done for infants with SEC.</p>
