At a median follow-up of 12 months, 101 children had resolution of neutropenia, 40 children had mild neutropenia, 10 children had moderate neutropenia, 3 children had severe neutropenia, and 1 patient had very severe neutropenia. A specific diagnosis was not identified in most (54%) children. The most common etiologies were viral suppression (16%), autoimmune neutropenia (14%), and drug-induced neutropenia (8%). Black children had a 3.5 higher odds of having persistent mild neutropenia. Six (4%) children received granulocyte colony-stimulating factor therapy. Most children referred for isolated neutropenia do not progress in severity and do not require subspecialty interventions or hospitalizations.Most children referred for isolated neutropenia do not progress in severity and do not require subspecialty interventions or hospitalizations. To determine impact of a primary care-based child obesity prevention intervention beginning during pregnancy on early childhood weight outcomes in low-income Hispanic families. A randomized controlled trial comparing mother-infant pairs receiving either standard care or the Starting Early Program providing prenatal and postpartum nutrition counseling and nutrition parenting support groups targeting key obesity-related feeding practices in low-income groups. Primary outcomes were reduction in weight-for-age -scores (WFAzs) from clinical anthropometric measures, obesity prevalence (weight for age ≥95th percentile), and excess weight gain (WFAz trajectory) from birth to age 3 years. Secondary outcomes included dose effects. Pregnant women ( = 566) were enrolled in the third trimester; 533 randomized to intervention ( = 266) or control ( = 267). Also, 358 children had their weight measured at age 2 years; 285 children had weight measured at age 3 years. Intervention infants had lower mean WFAz at 18 months (0.49 vs 0.73, = .04) and 2 years (0.56 vs 0.81, = .03) but not at 3 years (0.63 vs 0.59, = .76). No group differences in obesity prevalence were found. When generalized estimating equations were used, significant average treatment effects were detected between 10-26 months (B = -0.19, = .047), although not through age 3 years. In within group dose analyses at 3 years, obesity rates (26.4%, 22.5%, 8.0%, = .02) decreased as attendance increased with low, medium, and high attendance. Mean WFAz and growth trajectories were lower for the intervention group through age 2 years, but there were no group differences at age 3. Further study is needed to enhance sustainability of effects beyond age 2.Mean WFAz and growth trajectories were lower for the intervention group through age 2 years, but there were no group differences at age 3.

Catheter insertion bundles (IBs) and maintenance bundles (MBs) have been developed to prevent CAUTIs but have not been extensively validated for use in pediatric populations. We report the CAUTI prevention efforts of a large network of children's hospitals. Children's hospitals joined the Children's Hospitals' Solutions for Patient Safety engagement network from 2011 to 2017, using an open start time engagement approach, and elected to participate in CAUTI prevention efforts, with 26 submitting data initially and 128 at the end. CAUTI prevention recommendations were first released in May 2012, and IBs and MBs were released in May 2014. Hospitals reported on CAUTIs, patient-days, and urinary catheter-line days and tracked reliability to each bundle. For the network, run charts or control charts were used to plot CAUTI rates, urinary catheter use, and reliability to each bundle component. After the introduction of the pediatric CAUTI IBs and MBs, CAUTI rates across the network decreased 61.6%, from 2.55 to 0.98 infections per 1000 catheter-line days. Centerline shifts occurred both before and after the 2015 Centers for Disease Control and Prevention CAUTI definition change. DNA Repair inhibitor Urinary catheter use rates did not decline during the intervention period. Network reliability to the IBs and MBs increased to 95.4% and 86.9%, respectively. IBs and MBs aimed at preventing CAUTIs were introduced across a large network of children's hospitals. Across the network, the rate of urinary tract infections among hospitalized children with indwelling urinary catheters decreased 61.6%.IBs and MBs aimed at preventing CAUTIs were introduced across a large network of children's hospitals.

Sexual stage maturation occurs in the midgut of the mosquito vector, where male and female gametes egress from the host erythrocytes to fuse and form a zygote. Gamete egress entails the successive rupture of two membranes surrounding the parasite, the parasitophorous vacuole membrane and the erythrocyte plasma membrane. In this study, we used the rodent model parasite Plasmodium berghei to design a label-free quantitative proteomic approach aimed at identifying gender-related proteins differentially released/secreted by purified mature gametocytes when activated to form gametes. We compared the abundance of molecules secreted by wild type gametocytes of both genders with that of a transgenic line defective in male gamete maturation and egress. This enabled us to provide a comprehensive data set of egress-related molecules and their gender specificity. Using specific antibodies, we validated eleven candidate molecules, predicted as either gender-specific or common to both male and female gametocytes. All of them localize to punctuate, vesicle-like structures that relocate to cell periphery upon activation, but only three of them localize to the gametocyte-specific secretory vesicles named osmiophilic bodies. Our results confirm that the egress process involves a tightly coordinated secretory apparatus that includes different types of vesicles and may put the basis for functional studies aimed at designing novel transmission-blocking molecules.
