OBJECTIVES: To study the predictive value of hemoglobin (Hb) decrease for the occurrence of necrotizing enterocolitis (NEC) in preterm infants with late-onset sepsis (LOS) . METHODS: Clinical data of 93 LOS preterm infants were collected for retrospective analysis, among which 16 infants developed NEC while 77 infants did not. Based on the decrease in Hb levels from the most recent Hb measurement before LOS occurrence to the initial Hb levels during LOS, the infants were divided into three groups: no Hb decrease (n=15), mild Hb decrease (Hb decrease <15 g/L; n=35), and severe Hb decrease (Hb decrease ≥15 g/L; n=43). Multivariate logistic regression analysis was conducted to explore the predictive factors for NEC secondary to LOS, and the value of Hb decrease in predicting NEC secondary to LOS was evaluated through receiver operating characteristic curve analysis. RESULTS: The incidence of NEC in the severe Hb decrease group, mild Hb decrease group, and no Hb decrease group were 26%, 14%, and 0% (P<0.05), respectively. Multivariate logistic regression analysis revealed that a larger Hb decrease was an independent predictive factor for NEC in LOS preterm infants (OR=1.141, 95%CI: 1.061-1.277, P<0.001). Receiver operating characteristic curve analysis showed that the area under the curve for predicting NEC in preterm infants with LOS using Hb decrease (with a cut-off value of 20 g/L) was 0.803, with sensitivity and specificity of 0.69 and 0.78, respectively. CONCLUSIONS: Hb decrease can serve as an indicator for prediction of NEC in preterm infants with LOS.

[Surgical ventricular restoration versus isolated coronary artery bypass grafting for left ventricular aneurysm: comparison of mid- to long-term outcomes].

OBJECTIVE: To compare the mid- to long-term outcomes of patients receiving isolated coronary artery bypass grafting (CABG) versus surgical ventricular restoration (SVR) plus CABG for left ventricular aneurysms. METHODS: The clinical data were retrospectively analyzed in 205 patients with left ventricular aneurysms admitted to our hospital between January, 1997 and December, 2012, including 115 patients receiving SVR plus CABG and 90 undergoing isolated CABG. By matching preoperative echocardiographic parameters including aneurysm size, left ventricular ejection fraction (LVEF), left ventricular end-systolic volume index (LVESVI) and EuroSCORE risk factors, 32 patients receiving SVR plus CABG and another 32 with isolated CABG were enrolled in this study. The patients were compared for survival rates, major adverse cardiac or cerebrovascular events (MACCEs), left ventricular geometry and function at 1, 3 and 5 years of follow-up. RESULTS: Compared with the patients receiving isolated CABG, those receiving SVR and CABG showed greater improvements in echocardiographic parameters and NYHA functional class. The differences in the echocardiographic parameters between the two groups gradually reduced with time and became comparable at 5 years after the operation (P>0.05). No significant difference was found in the mid- to long-term survival or the incidence of MACCEs between the two groups (P>0.05). CONCLUSION: Compared with isolated CABG, SVR plus CABG does not reduce the incidence of MACCEs or improve the mid- to long-term survival rate of patients with left ventricular aneurysm with a LVESVI <60 mL/m(2).

[Different approaches to revascularization for complex coronary artery disease and left ventricular dysfunction: analysis of perioperative outcomes].

OBJECTIVE: To compare the perioperative outcomes of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for treatment of complex coronary artery disease and left ventricular dysfunction. METHDOS: The clinical data of 966 patients admitted to our hospital from January 2003 to December 2013 with coronary artery disease and left ventricular dysfunction (ejection fraction ≤50%) were retrospectively reviewed. Among the patients, 386 underwent CABG and 580 received PCI. After matching for EuroSCORE risk factors and preoperative echocardiographic parameters, 135 patients with CABG and 135 with PCI were enrolled in this study. With hospital mortality and perioperative major complications as the endpoints, the early outcomes of the procedures were evaluated. Perioperative echocardiography was performed to evaluate the change of left ventricular geometry and function. RESULTS: Compared with CABG group, PCI group had significantly higher incidences of chronic lung disease (8.1% vs 0.7%, P=0.003) and recent myocardial infarction (64.4% vs 31.9%, P=0.000) but significantly lower left-main disease (12.6% vs 23.7%, P=0.018); the other baseline characteristics were comparable between the two groups. Patients with CABG had a greater number of treated target vessels than those with PCI (2.90±0.81 vs 1.67±0.73, P=0.000), and complete revascularization was more common in CABG group (94.8% vs 51.8%, P=0.000). No significant difference was found in perioperative variations of LVEF between the two groups, but patients with CABG had a greater variation in LVEDD than those with PCI. The hospital mortality and other major complications were similar between the two groups. CONCLUSION: Both CABG and PCI are safe and reliable revascularization strategies for complex coronary artery disease and left ventricular dysfunction, but CABG can achieve a higher rate of complete revascularization and better improves the left ventricular function.

Sublingual Immunotherapy for Asthmatic Children Sensitized to House Dust Mite: A Meta-Analysis.

The house dust mite is one of the most common allergens worldwide. There is good evidence that house dust mite subcutaneous immunotherapy is efficacious and has long-term benefit in children. However, the evidence of the benefit of house dust mite sublingual immunotherapy (SLIT) is less convincing. The purpose of this meta-analysis was to evaluate that efficacy and safety of dust mite SLIT in children with asthma. Medical Literature Analysis and Retrieval System Online, ISI Web of Knowledge, and Cochrane Central Register of Controlled Trials databases until February 2014 were searched. The primary outcome was mean change in asthma symptom score. Secondary outcomes included mean change in serum immunoglobulin G4 (sIgG4), specific Dermatophagoides pteronyssinus, immunoglobulin E (IgE) levels, and medication score. Safety was also assessed. We found that SLIT significantly decreased asthma symptom score (P = 0.007) and increased sIgG4 levels (P = 0.011) greater than control in children (<18 years of age) with asthma. There was no difference between SLIT and control groups in specific D pteronyssinus IgE levels (P = 0.076) and medication score (P = 0.408). The safety profile was similar between groups. Our study indicates that dust mite SLIT therapy was effective in reducing asthma symptoms and in increasing sIgG4 but did not significantly reduce medication scores or specific D pteronyssinus IgE levels. Our findings are not enough to support the use of dust mite SLIT in children with asthma.
