Expectations are high that electronic health record–based clinical decision support and performance feedback will improve adherence to guidelines by delivering relevant and actionable information to clinicians. Few studies have evaluated these assertions or examined the combined effects of decision support and feedback.

Clinical decision support customized to a patient’s history and presentation and performance feedback are both effective for improving adherence to guidelines for otitis media. However, the combination of the 2 interventions is no better than either delivered alone. (Read the full article)

Rates of screen media use have risen in parallel with rates of obesity among young people. Identifying the specific characteristics of media use that are associated with obesity can help elucidate the explanatory processes and inform effective interventions.

This study examines the associations between BMI and characteristics of media use including the type of device, duration of use, and attention to the medium. The more that participants paid primary attention to television, the higher their BMI. (Read the full article)

Atherosclerotic cardiovascular diseases are rooted in childhood. Vascular intima-media thickness (IMT) and elasticity are early surrogate markers of atherosclerosis. In adults, cardiorespiratory fitness is associated with enhanced arterial elasticity and decreased IMT.

Fitness was favorably associated with aortic IMT and elasticity in adolescents. The association was independent of several cardiometabolic risk factors. In fit adolescents, the increase in IMT during the preceding 6 years was smaller compared with low-fit peers. (Read the full article)

Children with autism spectrum disorders (ASD) or attention-deficit/hyperactivity disorder (ADHD) are at increased risk for sleep disturbances and excessive media use. However, the relationship between media use and sleep in children with ASD or ADHD has not been studied.

In-room access to screen-based media and video game hours were associated with less sleep among boys with ASD. The relationships between media use and sleep were much more pronounced among boys with ASD than among boys with ADHD or typical development. (Read the full article)

Xylitol given as a gum or syrup 5 times daily has been shown to reduce the incidence of acute otitis media in children, but this dosing schedule is unlikely to be feasible for many families.

A regimen of viscous xylitol syrup in a dose of 5 g 3 times daily was ineffective in preventing recurrences of acute otitis media in otitis-prone children. (Read the full article)

Several studies suggest that excessive media use in early childhood predicts poorer developmental outcomes. It has not been studied whether infants with self-regulation problems, who may be at higher developmental risk, develop excessive media use habits.

This study shows that infants and toddlers with self-regulation difficulties (ie, problems with self-soothing, sleep, emotional regulation, and attention) view more media at 2 years of age, independent of other important confounders. (Read the full article)

Mixed results exist regarding the efficacy of caregiver-mediated interventions for children who have ASD. To date, randomized controlled studies have rarely compared 2 active interventions; none have focused on targeting families who are low-resourced in the community.

Significant improvements were found in social communication of children who have autism when caregivers received a hands-on caregiver training intervention in the home. These are the first data from a low-intensity, short-term intervention with low-resourced families. (Read the full article)

A previous study suggested that physicians in 1 practice network were less likely to diagnose otitis media (OM) and to prescribe broad-spectrum antibiotics for OM for black versus nonblack children.

Nationally, black children with OM are more likely to receive guideline-recommended, narrow-spectrum antibiotics than nonblack children. These findings may reflect inappropriate treatment of OM with the use of broad-spectrum antibiotics in a majority of US children. (Read the full article)

Parental depression is associated with adverse child outcomes. It is important to understand possible mediators and moderators. Several studies suggest that the family environment or parenting style may be potential pathways for transmission of risk from parents to children.

Paternal depression appears to exert its influence on children’s outcomes through an effect on family functioning (couple conflict and maternal depression), whereas maternal postnatal depression appears to affect children through other mechanisms, potentially including direct mother-infant interaction and care.

Interactive mobile media devices have revolutionized children’s access to and experience of media, but research is lagging behind its adoption. A critical first step is to understand when and how young children adopt mobile media devices.

Our study found almost universal exposure, early adoption, and use of mobile media devices among young children in an urban, low-income, minority community. Studies are needed to update guidelines on the use of mobile media by young children. (Read the full article)

Burundi’s year-long crisis has not gone away. It started with President Pierre Nkurunziza’s determination to claim a third term, trampling over the constitutional arrangements that ended a decade-long civil war. Press freedom is a major casualty of the new strife; but the turmoil has also transformed the way in which Burundians get information. For better or worse, social media has filled the vacuum left by the shutting down of the most popular radio stations and forcing out of many of the country’s professional journalists.

Polymyxins are increasingly used as the critical last-resort therapeutic options for multidrug-resistant gram-negative bacteria. Unfortunately, polymyxin resistance has increased gradually for the last few years. Although studies on mechanisms of polymyxin are expanding, system-wide analyses of the underlying mechanism for polymyxin resistance and stress response are still lacking. To understand how Klebsiella pneumoniae adapt to colistin (polymyxin E) pressure, we carried out proteomic analysis of Klebsiella pneumoniae strain cultured with different concentrations of colistin. Our results showed that the proteomic responses to colistin treatment in Klebsiella pneumoniae involving several pathways, including (i) gluconeogenesis and TCA cycle; (ii) arginine biosynthesis; (iii) porphyrin and chlorophyll metabolism; and (iv) enterobactin biosynthesis. Interestingly, decreased abundance of class A β-lactamases including TEM, SHV-11, SHV-4 were observed in cells treated with colistin. Moreover, we also present comprehensive proteome atlases of paired polymyxin-susceptible and -resistant Klebsiella pneumoniae strains. The polymyxin-resistant strain Ci, a mutant of Klebsiella pneumoniae ATCC BAA 2146, showed missense mutation in crrB. The crrB mutant Ci, which displayed lipid A modification with 4-amino-4-deoxy-L-arabinose (L-Ara4N) and palmitoylation, showed striking increases of CrrAB, PmrAB, PhoPQ, ArnBCADT and PagP. We hypothesize that crrB mutations induce elevated expression of the arnBCADTEF operon and pagP via PmrAB and PhoPQ. Moreover, multidrug efflux pump KexD, which was induced by crrB mutation, also contributed to colistin resistance. Overall, our results demonstrated proteomic responses to colistin treatment and the mechanism of CrrB-mediate colistin resistance, which may further offer valuable information to manage polymyxin resistance.

Chromosomal and plasmid-borne AmpC cephalosporinases are a major resistance mechanism to β-lactams in Enterobacteriaceae and Pseudomonas aeruginosa. The new β-lactamase inhibitor avibactam effectively inhibits class C enzymes and can fully restore ceftazidime susceptibility. The conserved amino acid residue Asn³⁴⁶ of AmpC cephalosporinases directly interacts with the avibactam sulfonate. Disruption of this interaction caused by the N³⁴⁶Y amino acid substitution in Citrobacter freundii AmpC was previously shown to confer resistance to the ceftazidime-avibactam combination (CAZ-AVI). The aim of this study was to phenotypically and biochemically characterize the consequences of the N³⁴⁶Y substitution in various AmpC backgrounds. Introduction of N³⁴⁶Y into Enterobacter cloacae AmpC (AmpC_cloacae), plasmid-mediated DHA-1, and P. aeruginosa PDC-5, led to 270-, 12,000-, and 79-fold decreases in the inhibitory efficacy (k₂/K_i) of avibactam, respectively. The kinetic parameters of AmpC_cloacaeand DHA-1 for ceftazidime hydrolysis were moderately affected by the substitution. Accordingly, AmpC_cloacaeand DHA-1 harboring N³⁴⁶Y conferred CAZ-AVI resistance (MIC of ceftazidime of 16 µg/ml in the presence of 4 µg/ml of avibactam). In contrast, production of PDC-5 N³⁴⁶Y was associated with a lower MIC (4 µg/ml) since this β-lactamase retained a higher inactivation efficacy by avibactam in comparison to AmpC_cloacaeN³⁴⁶Y. For FOX-3, the I³⁴⁶Y substitution did not reduce the inactivation efficacy of avibactam and the substitution was highly deleterious for β-lactam hydrolysis, including ceftazidime, preventing CAZ-AVI resistance. Since AmpC_cloacaeand DHA-1 display substantial sequence diversity, our results suggest that loss of hydrogen interaction between Asn³⁴⁶ and avibactam could be a common mechanism of acquisition of CAZ-AVI resistance.

Florfenicol belongs to a class of phenicol antimicrobials widely used as feed additives and for the treatment of respiratory infections. In recent years, increasing resistance to florfenicol has been reported in Campylobacter spp., the leading foodborne enteric pathogen causing diarrheal diseases worldwide. Here, we reported the identification of fexA, a novel mobile florfenicol resistance gene in Campylobacter. Of the 100 Campylobacter jejuni strains isolated from poultry in Zhejiang, China, nine of them were shown to be fexA positive, and their whole genome sequences were further determined by integration of Illumina short-read and MinION long-read sequencing. The fexA gene was found in the plasmid of one strain and chromosomes of eight strains, and its location was verified by S1 nuclease pulsed-field gel electrophoresis (S1-PFGE) and Southern blotting. Based on comparative analysis, the fexA gene was located within a region with the tet(L)-fexA-catA-tet(O) gene arrangement, demonstrated to be successfully transferrable among C. jejuni strains. Functional cloning indicated that acquisition of the single fexA gene significantly increased resistance to florfenicol, whereas its inactivation resulted in increased susceptibility to florfenicol in Campylobacter. Taken together, these results indicated that the emerging fexA resistance is horizontally transferable, which might greatly facilitate the adaptation of Campylobacter in food producing environments where florfenicols are frequently used.

BACKGROUND:

Elevated non–high-density lipoprotein cholesterol (HDL-C) levels are used to identify children at increased cardiovascular risk, but the use of non–HDL-C in childhood to predict atherosclerosis is unclear. We examined whether the National Heart, Lung, and Blood Institute classification of youth non–HDL-C status predicts high common carotid artery intima-media thickness in adulthood.
