WHAT'S KNOWN ON THIS SUBJECT:Immune response to some vaccines is different among breastfed infants compared with those who are not breastfed. WHAT THIS STUDY ADDS:Breastfed infants are less likely to have fever after routine immunizations.abstract OBJECTIVE: The objective of this study was to evaluate the effects of breastfeeding on the risk for fever after routine immunizations. METHODS:A prospective cohort study was conducted at a pediatric vaccination center in Naples, Italy. The mothers of the infants scheduled to receive routine immunizations were instructed on how to measure and record infant temperature on the evening of the vaccination and for the subsequent 3 days. The information about the incidence of fever was obtained by telephone on the third day after vaccination. The relative risk for fever in relation to the type of breastfeeding was estimated in multivariate analyses that adjusted for vaccine dose, maternal education and smoking, and number of other children in the household. RESULTS:A total of 460 infants were recruited, and information on the outcome was obtained for 450 (98%). Fever was reported for 30 (25%), 48 (31%), and 94 (53%) of the infants who were being exclusively breastfed, partially breastfed, or not breastfed at all, respectively (P Ͻ .01). The relative risk for fever among infants who were exclusively and partially breastfed was 0.46 (95% confidence interval: 0.33-0.66) and 0.58 (95% confidence interval: 0.44 -0.77), respectively. The protection conferred by breastfeeding persisted even when considering the role of several potential confounders. CONCLUSIONS:In this study, breastfeeding was associated with a decreased incidence of fever after immunizations.

Objective To determine pregnancy outcome in women with atrial switch repair for transposition of the great arteries (TGA) and to compare follow up with a control group of childless women with the same repair.Design Retrospective cohort study.Setting Tertiary care medical centre.Population About 21 patients compared with 15 controls.Methods Review of records from joint cardiac-obstetric clinic 1993-2013.Main outcome measures Occurrence of cardiovascular events: maternal death, heart failure, arrhythmia, thromboembolic events, worsening systemic ventricular function, worsening tricuspid valve regurgitation and newly detected baffle problems.Results There were 34 pregnancies in 21 women. Mean follow up was 100 months. No deaths or recurrence occurred. Events (few arrhythmias, thromboembolic events and baffle issues) were common in both groups: 13 (62%) patients and eight (53%) controls (P = 0.736). Worsening of ventricular function was similar in both groups: six (29%) patients and four (27%) controls (P = 0.899). Worsening tricuspid regurgitation was more common in patients [11 (52%)] than controls (0)] (P < 0.001). Labour was induced in 76% cases: 32% for cardiac deterioration, 37% to control timing of delivery, and 26% for intrauterine growth restriction. Delivery was vaginal in 84% cases. Median gestational age was 37 (30-40) weeks, median birthweight 2525 g (1460-3530). In all, 38% babies were premature and 38% were small-for-gestational-age.Conclusions Cardiac events after atrial repair for TGA are equally common in pregnant women and non-pregnant controls, although worsening tricuspid regurgitation occurs more frequently in pregnancy. Induction of labour is to be expected but vaginal delivery is achievable in most cases. Infants are likely to be premature and small-for-gestational-age.Keywords Atrial repair pregnancy, congenital heart disease, transposition of the great arteries.Tweetable abstract Pregnancy in atrial repair for TGA: cardiac events similar to controls, prematurity and small babies likely.

The development of a progressive course is by far the most deleterious event in the case of a multiple sclerosis (MS) patient. It occurs in about 90% of relapsing remitting patients by 20-25 years from onset. The clinical transition to secondary progressive MS is phenotypically distinctive and both patients and physicians acknowledge that a fundamental shift in the degree of responsiveness to anti-inflammatory therapies has occurred. This review discusses the clinical studies that provided important findings relating to our understanding on different mechanisms that may contribute to irreversible disability in MS.

There was no maternal or neonatal mortality and an overall acceptable incidence of cardiovascular events but a relevant percentage of pregnant were first referred late and/or for the onset of symptoms. Events were more frequent in these patients. Further efforts are needed to optimize referral to specialized centers.

A female baby suffered from a rare association between histiocytoid cardiomyopathy, left ventricular non-compaction, and Wolff-Parkinson-White syndrome causing severe and recurrent arrhythmic storms. Antiarrhythmic drugs, radiofrequency ablation of Purkinje tissue, and sympathetic denervation were ineffective. The implant of a cardiac defibrillator allowed her to survive till heart transplant. Compound mutation of CACNA2D1 and RANGRF genes were found. To the best of our knowledge, this is the first comprehensive description of the concurrence of these two mutations and histiocytoid cardiomyopathy.
