Growth assessment in preterm children from birth to preschool age
Preterm infant growth is a major health indicator and needs to be monitored with an appropriate growth curve to achieve the best developmental and growth potential while avoiding excessive caloric intake that is linked to metabolic syndrome and hypertension later in life. New international standards for size at birth and postnatal growth for preterm infants are available and need implementation in clinical practice. A prospective, single center observational study was conducted to evaluate the in-hospital and long-term growth of 80 preterm infants with a mean gestational age of 33.3 ± 2.2 weeks, 57% males. Size at birth and at discharge were assessed using the INTERGROWTH-21ST standards, at preschool age with World Health Organization (WHO) child growth standards. The employment of INTERGROWTH-21ST Preterm Postnatal longitudinal standards during the in-hospital follow-up significantly reduced the diagnosis of short term extrauterine growth restriction when compared to commonly used cross sectional neonatal charts, with significant lower loss of percentiles between birth and term corrected age (p < 0.0001). The implementation of a package of standards at birth, preterm postnatal growth standards and WHO child growth standards proved to be consistent, with correlation between centile at birth and at follow-up, and therefore effective in monitoring growth in a moderate and late preterm infant cohort without chronic or major morbidities. Infants identified as small for gestational age at birth showed significantly more frequently a need for auxological referral
Novel artful applications of vaccines at the horizon
Some live vaccines, particularly Bacillus Calmette-Guerin (BCG), oral polio vaccine (OPV), and measles vaccine, can reduce the incidence of all-cause mortality by outreaching the mere control of specific infections and exerting off-target effects. Asides from the prevention of viral infection, some other vaccines, such as those against flu or rotavirus, could reduce the risk of developing autoimmunity. The nonspecific effects of vaccines are mediated by the innate immune system, mainly through the so-called trained innate immunity. These observations paved the way for developing tolerogenic and trained immunity-based vaccines with substantial implications for more effective use of vaccines and combat vaccine hesitancy
Antagonistic effect of Lactobacillus strains against gas-producing coliforms isolated from colicky infants
<p>Abstract</p> <p>Background</p> <p>Infantile colic is a common disturb within the first 3 months of life, nevertheless the pathogenesis is incompletely understood and treatment remains an open issue. Intestinal gas production is thought to be one of the causes of abdominal discomfort in infants suffering from colic. However, data about the role of the amount of gas produced by infants' colonic microbiota and the correlation with the onset of colic symptoms are scanty. The benefit of supplementation with lactobacilli been recently reported but the mechanisms by which they exert their effects have not yet been fully defined. This study was performed to evaluate the interaction between <it>Lactobacillus </it>spp. strains and gas-forming coliforms isolated from stools of colicky infants.</p> <p>Results</p> <p>Strains of coliforms were isolated from stools of 45 colicky and 42 control breastfed infants in McConkey Agar and identified using PCR with species-specific primers, and the BBL™ Enterotube™ II system for <it>Enterobacteriaceae</it>. Gas-forming capability of coliforms was assessed in liquid cultures containing lactose as sole carbon source. The average count of total coliforms in colicky infants was significantly higher than controls: 5.98 (2.00-8.76) log<sub>10 </sub><it>vs </it>3.90 (2.50-7.10) CFU/g of faeces (p = 0.015). The following strains were identified: <it>Escherichia coli</it>, <it>Klebsiella pneumoniae</it>, <it>Klebsiella oxytoca</it>, <it>Enterobacter aerogenes</it>, <it>Enterobacter cloacae </it>and <it>Enterococcus faecalis</it>. Then, 27 <it>Lactobacillus </it>strains were tested for their antagonistic effect against coliforms both by halo-forming method and in liquid co-cultures. <it>Lactobacillus delbrueckii </it>subsp.<it>delbrueckii </it>DSM 20074 and <it>L. plantarum </it>MB 456 were able to inhibit all coliforms strains (halo-forming method), also in liquid co-cultures, thus demonstrating an antagonistic activity.</p> <p>Conclusions</p> <p>This study shows that two out of 27 strains of <it>Lactobacillus </it>examined possess an antimicrobial effect against six species of gas-forming coliforms isolated from colicky infants. Our findings may stimulate new researches to identify which <it>Lactobacillus </it>strains can improve colicky symptoms by acting on coliforms gut colonization.</p
Lidocaine treatment in refractory status epilepticus resulting from febrile infection-related epilepsy syndrome: a case report and follow-up.
Efficacy of ketamine in refractory convulsive status epilepticus in children: A protocol for a sequential design, multicentre, randomised, controlled, open-label, non-profit trial (KETASER01)
Introduction: Status epilepticus (SE) is a lifethreatening neurological emergency. SE lasting longer than 120 min and not responding to first-line and second-line antiepileptic drugs is defined as 'refractory' (RCSE) and requires intensive care unit treatment. There is currently neither evidence nor consensus to guide either the optimal choice of therapy or treatment goals for RCSE, which is generally treated with coma induction using conventional anaesthetics (high dose midazolam, thiopental and/or propofol). Increasing evidence indicates that ketamine (KE), a strong N-methyl-D-aspartate glutamate receptor antagonist, may be effective in treating RCSE. We hypothesised that intravenous KE is more efficacious and safer than conventional anaesthetics in treating RCSE. Methods and analysis: A multicentre, randomised, controlled, open-label, non-profit, sequentially designed study will be conducted to assess the efficacy of KE compared with conventional anaesthetics in the treatment of RCSE in children. 10 Italian centres/ hospitals are involved in enrolling 57 patients aged 1 month to 18 years with RCSE. Primary outcome is the resolution of SE up to 24 hours after withdrawal of therapy and is updated for each patient treated according to the sequential method. Ethics and dissemination: The study received ethical approval from the Tuscan Paediatric Ethics Committee (12/2015). The results of this study will be published in peer-reviewed journals and presented at international conferences
