RESUMO
OBJECTIVE: This study aimed to identify the most useful ultrasound (US) features associated with definite neonatal necrotizing enterocolitis (NEC) and their prognostic values, particularly the calculated markers combined with important features. METHODS: A total of 213 suspected NEC cases were collected from the neonatal department of our hospital from January 2015 to August 2017. Each infant received both X-ray and US examinations. RESULTS: No differences were found in sex composition and delivery modes between groups. NEC-positive neonates had poorer prognosis compared to negative ones. The NEC group showed a higher frequency of abnormal signals. US showed higher NEC-related frequencies in different parameters. A variable (named predictor in US [PUS]) with five features was constructed. For NEC diagnosis, this variable provided a much higher area under the curve Q2 (AUC) (0.965) than other parameters. In this model, PUS had a cutoff value of 0.376 with a 0.900 sensitivity and 0.922 specificity. In prognosis, the closest factors were selected to draw a receiver operating characteristic curve, as well as a novel calculated variable US prognostic (USPro) marker. USPro had a much higher AUC (0.86) than other single features and showed a cutoff value of 0.18145, with 0.75 sensitivity and 0.84 specificity. This variable had a weaker power in prognosis when compared with PUS in diagnosis. CONCLUSIONS: The application of abdominal color Doppler US can provide high accuracy and sensitivity in NEC diagnosis and also contribute to its prognosis, without induction of radiation. Suspected neonates should be examined using this technique as early as possible.

OBJECTIVE: To explore whether family integrated care (FICare) is feasible and improves the outcomes of preterm infants in China. STUDY DESIGN: This was a multicenter prospective cluster-randomized controlled trial comparing FICare and standard care. The primary outcome was length of stay (LOS). Secondary outcomes were nosocomial infections, duration of supplemental oxygen, breastfeeding, and weight gain. Outcomes were compared using univariate and multivariable analyses adjusted for potential confounders and clustering. RESULTS: We enrolled 601 preterm infants from 11 neonatal intensive care units (FICare, n = 298; control, n = 303). The unadjusted LOS was 30.81 vs 30.26 days (mean ratio, 1.02; 95% CI, 0.85-1.22; P = .85). After adjustment, outcomes in the FICare group were improved compared with the control group, including LOS (28.26 vs 35.04 days; mean ratio, 0.81; 95% CI, 0.72-0.91), total medical expenditures (mean ratio, 0.69; 95% CI, 0.53-0.90), weight gain velocity (15.73 vs 10.30 g/day; mean difference, 5.43; 95% CI, 3.65-7.21), duration of supplemental oxygen (13.11 vs 21.42 days; mean difference, 0.71; 95% CI, 0.50-1.00), nosocomial infection rates (4.13 vs 5.84/1000 hospital days; mean ratio, 0.67; 95% CI, 0.47-0.96), antibiotic exposure (38.63 vs 57.32/100 hospital days; mean ratio, 0.67; 95% CI, 0.47-0.96), breastfeeding rates (87.25% vs 55.78%; OR, 5.42; 95% CI, 3.25-9.05), and rehospitalization rates (3.65% vs 7.48%; OR, 0.47; 95% CI, 0.28-0.77). At follow-up to 18 months, breastfeeding rates and weight were significantly (P < .05) higher over time in the FICare group. CONCLUSIONS: FICare was feasible in Chinese neonatal intensive care units and was associated with reduced hospital LOS, medical expenditures, and rates of adverse outcomes.
