Reducing post-extubation failure rates in very preterm infants: is BiPAP better than CPAP?

BACKGROUND AND AIM: Continuous positive airway pressure (CPAP) is currently used in neonates after mechanical ventilation though it may occasionally be associated with air leaks syndromes or it may fail to support the baby. The pressure difference offered by bilevel continuous positive distending pressure (BiPAP) respect to CPAP may be an advantage to the spontaneously breathing patient. In this study, we compared the efficacy of CPAP and BiPAP in the firstweek post-extubation in a series of very preterm infants. METHODS: Inborn neonates less than 30 weeks of gestational age who were intubated shortly after birth from January 2011 to December 2017 were enrolled in a retrospective study. The attending clinician assessed the patients for non-invasive respiratory support readiness and allocated them to CPAP (PEEP 4-6 cmH2O) or BiPAP (PEEP 4-5 cmH2O, rate 10-40; Thigh 0.7-1.2; upper-pressure level 8-10 cmH2O). Both techniques were compared for preventing extubation failure within 7 days from extubation as defined per local protocol (primary outcome). Secondary outcomes were: definitive failure of extubation, pneumothorax during non-invasive respiratory support, periventricular leukomalacia, bronchopulmonary dysplasia, sepsis, patent ductus arteriosus and retinopathy of prematurity at discharge. RESULTS: We enrolled 134 neonates; the CPAP group included 89 babies while 45 received BiPAP. Patients did not differ for their general characteristics (EG, antenatal steroids, incidence of SGA, maternal hypertension, surfactant replacement therapy). Short term extubation failure was significantly higher in the former group (23/89 in CPAP vs 5/45 in BiPAP; p = .005). No infant developed air leak syndrome. Secondary outcomes were comparable between groups. Multivariate analysis showed that on the whole population the extubation failure was correlated to the insurgence of late-onset sepsis. CONCLUSION: BiPAP safely reduced early extubation failure compared to CPAP in our cohort of very preterm neonates within 7 days from extubation.

Reduced central line infection rates in children with leukemia following caregiver training: A quality improvement study.

Infections are a leading cause of morbidity and mortality in children with acute leukemia. Central-line (CL) devices increase this population's risk of serious infections.Within the context of a quality improvement (QI) project, we tested the effect of caregiver education on CL management on the CL-associated bloodstream infection (CLABSI) rate among children with acute leukemia seen at a large referral center in Italy. The intervention consisted of 9 in-person sessions for education and practice using mannequins and children.One hundred and twenty caregivers agreed to participate in the initiative. One hundred and five (87.5%) completed the training, 5 (4.1%) withdrew after the first session, and 10 (8.3%) withdrew during practical sessions. After educational intervention, the overall CLABSI rate was reduced by 46% (from 6.86 to 3.70/1000 CL-days). CLABSI rate was lower in children whose caregivers completed the training (1.74/1000 CL-days, 95% CI 0.43-6.94) compared with those who did not receive any training (12.2/1000 CL-days, 95% CI 7.08-21.0, P < 0.05) or were in-training (3.96/1000 CL-days, 95% CI 1.98-7.91) at the time of infection.Caregiver training in CL management, applied within a multifaceted QI approach, reduced the rate of CLABSI in children with acute leukemia. Specific training and active involvement of caregivers in CL management may be effective to reduce CLABSI in high-risk children.

Relationship between severe obesity and gut inflammation in children: what's next?

BACKGROUND: Preliminary evidence suggests an association between obesity and gut inflammation. AIMS: To evaluate the frequency of glucose abnormalities and their correlation with systemic and intestinal inflammation in severely obese children. PATIENTS AND METHODS: Thirty-four children (25 males; median age 10.8 ± 3.4 yrs) with severe obesity (BMI >95%) were screened for diabetes with oral glucose tolerance test (OGTT), systemic inflammation with C-reactive protein (CRP) and gut inflammation with rectal nitric oxide (NO) and faecal calprotectin. RESULTS: BMI ranged from 23 to 44 kg/m2, and BMI z-score between 2.08 e 4.93 (median 2.69 ± 0.53). Glucose abnormalities were documented in 71% of patients: type 2 diabetes in 29%, impaired fasting glucose (IFG) in 58%, and impaired glucose tolerance (IGT) in 37.5%. Thirty-one patients (91%) were hyperinsulinemic. CRP was increased in 73.5% with a correlation between BMI z-score and CRP (p 0.03). Faecal calprotectin was increased in 47% patients (mean 77 ± 68), and in 50% of children with abnormal glucose metabolism (mean 76 ± 68 µg/g), with a correlation with increasing BMI z-score. NO was pathological in 88%, and in 87.5% of glucose impairment (mean 6.8 ± 5 µM). CONCLUSIONS: In this study, the prevalence of glucose abnormalities in obese children is higher than in other series; furthermore, a correlation is present between markers of systemic and intestinal inflammation and glucose abnormalities.
