RESUMO
(1) Background: The relationship between enteral nutrition and neonatal necrotizing enterocolitis (NEC) among premature neonates is still unclear. The present work was designed to assess the relationship between NEC and feeding strategies compared to control infants. (2) Methods: A retrospective case-control study of premature infants (<35 weeks' gestation) with or without NEC that examined feeding practices and clinical characteristics at birth and 3, 7, and 14-day hospitalization, with a longitudinal and cross-sectional analysis. (3) Results: A total of 100 newborns with NEC diagnosis and 92 neonates without the disease with similar demographic and clinical characteristics were included. The median day of NEC diagnosis was 15 days (Interquartile Range (IQR) 5-25 days). A significantly higher number of neonates that were fasting on days 7 and 14 developed NEC (p < 0.05). In the longitudinal analysis, generalized linear and mixed models were fit to evaluate NEC association with feeding strategies and showed that exclusive mother's own milk (MM) and fortified human milk (FHM) across time were significantly less likely associated with NEC (p < 0.001) and that enteral fasting was positively related with NEC. In the cross-sectional analysis, a binary logistic regression model was fit and predicted 80.7% of NEC cases. MM was also found to correlate with a reduced risk for NEC (OR 0.148, 95% CI 0.044-0.05, p = 0.02), and in particular, on day 14, several factors were related to a decreased odd for NEC, including birth weight, antenatal steroids, and the use of FHM (p < 0.001). (4) Conclusions: MM and FHM were associated with less NEC compared to fasting on days 7 and 14. Feeding practices in Neonatal Intensive Care Units (NICUs) should promote exclusive MM across the two-week critical period as a potential guideline to improve NEC outcome.
RESUMO
To evaluate the association of C-reactive protein (CRP) polymorphisms with risk of development SLE in a group of Mexican individuals. Five CRP polymorphisms (rs3093059, rs3093062, rs1800947, rs1130864, and rs1205) were determined by PCR-restriction fragment length polymorphism and SNP rs3093061 by refractory mutation system PCR assay in 126 SLE patients and 131 controls. Four of the polymorphisms showed differences between patients and controls. rs3093061 polymorphism was associated with a lower risk of developing lupus principally in the codominant 2 (OR = 0.219, 95% CI 0.108-0.785, P = 0.015) model. rs1130864 was associated with decreased risk mainly under codominant 1 (OR = 0.288, 95% CI 0.143-0.581, P = 0.001) model. rs1205 was associated under the over-dominant model (OR = 0.504, 95% CI 0.270-0.942, P = 0.032). The rs3091244 polymorphism was associated with decreased risk of SLE mostly under additive (OR = 0.605, 95% CI 0.393-0.931. P = 0.022) model. Our study establishes that rs3093061, rs1130864, rs1205, and rs3091244 polymorphisms are associated with decreased risk of developing SLE.

OBJECTIVES: To identify the causes and risk factors for hospitalisation in primary Sjögren's syndrome (pSS). METHODS: We included 170 pSS patients who regularly attended our Institution (2000-2013) and retrospectively collected demographic, clinical (glandular and extraglandular features) and serological (anti-Ro/SSA, anti-La/SSB, RF, low C3 or C4 and immunoglobulin levels) data. If they were hospitalised, a rheumatologist determined the primary cause. We registered the length of hospitalisation, need for Intensive Care Unit (ICU) admission, number of hospitalisations and death. The Disease Damage Index (SSDDI) (excluding the oral and ocular items) and the Charlson comorbidity Index were assessed. We used a logistic regression analysis and multiple imputation method for missing data. RESULTS: Fifty-five (32%) patients were hospitalised, representing 111 hospitalisations (28 patients had ≥1 hospital admission). The hospitalisation incidence density rate was 6.49/100 patient / years. The median length of hospital stay was 9 days (IQR 6-15), there were 7 ICU admissions and 6 deaths. The main causes of admissions were disease activity (33.3%) and infection (32.4%). At the multivariate analysis, the variables associated with hospitalisation were hepatic involvement (OR=5.4; 95% CI 1.61-18.15; p=0.006), vasculitis (OR=3.8; 95% CI 1.11-13.09; p=0.03), the SSDDI (OR=1.3; 95% CI 1.01-1.66; p=0.03) and the use of antimalarials (OR=0.08; 95% CI 0.02-0.22; p<0.001). CONCLUSIONS: The major causes for hospitalisation were disease activity and infection. Patients with hepatic involvement, vasculitis and more damage accrual had the highest risk for being hospitalised, while the use of antimalarials was protective.
