To evaluate the effects of a self-administered, digital behavioral parent training program on parent and child behavior for parents of young children.

A randomized controlled trial compared ezParent (digital delivery of the evidence-based Chicago Parent Program) with an enhanced usual-care control. Introduction to the study occurred during well-child visits at 4 primary care clinics. In total, 287 parents of children age 2-5years were randomized to ezParent or the control. Parents responded to surveys evaluating parent behavior, self-efficacy, and stress, and child behavior at baseline, and 3-, 6-, and 12-months postbaseline. Multilevel growth models examined parent and child outcomes for intervention efficacy in intent-to-treat analyses. Secondary moderation analysis explored intervention effects by program use and baseline parenting stress and child behavior problems.

The intervention main effect was not significant for parent and child behaviors. In exploratory moderation analysis, parents in the ezParent condition with greater baseline parenting stress reported less corporal punishment (P=.044); and greater improvement in parental warmth (P=.008), setting limits (P=.026), and proactive parenting (P=.019). Parents reporting greater baseline child behavior problems reported greater improvements in parental warmth (P=.007), setting limits (P=.003), and proactive parenting (P=.010). There were no differences in outcomes based on program usage.

Results suggest that ezParent as a self-administered behavioral parent training program may not be intense enough for child and parent behavioral change as a universal prevention model. Parents may require different levels of support for completion based on their level of service seeking, family characteristics, risk profile, and motivation for change.

To determine associations between a graded approach to intravenous (IV) dextrose treatment for neonatal hypoglycemia and changes in blood glucose (BG), length of stay (LOS), and cost of care.

Retrospective cohort study of 277 infants born at ≥35weeks of gestation in an urban academic delivery hospital, comparing the change in BG after IV dextrose initiation, neonatal intensive care unit (NICU) LOS, and cost of care in epochs before and after a hospital protocol change. During epoch 1, all infants who needed IV dextrose for hypoglycemia were given a bolus and started on IV dextrose at 60mL/kg/day. During epoch 2, infants received IV dextrose at 30 or 60mL/kg/day based on the degree of hypoglycemia. Differences in BG outcomes, LOS, and cost of hospital care between epochs were compared using adjusted median regression.

In epoch 2, the median (IQR) rise in BG after initiating IV dextrose (19 [10, 31] mg/dL) was significantly lower than in epoch 1 (24 [14,37] mg/dL; adjusted β = -6.0 mg/dL, 95% CI -11.2, -0.8). Time to normoglycemia did not differ significantly between epochs. NICU days decreased from a median (IQR) of 4.5 (2.1, 11.0) to 3.0 (1.5, 6.5) (adjusted β = -1.9, 95% CI -3.0, -0.7). Costs associated with NICU hospitalization decreased from a median (IQR) $14 030 ($5847, $30 753) to $8470 ($5650, $19 019) (adjusted β = -$4417, 95% CI -$571, -$8263) after guideline implementation.

A graded approach to IV dextrose was associated with decreased BG lability and length and cost of NICU stay for infants with neonatal hypoglycemia.

To report the intermediate-term outcome following surgical intervention for median arcuate ligament syndrome (MALS) in adolescents and young adults with orthostatic intolerance (OI) to assess clinical improvement in the gastrointestinal and 5 other functional domains and if relief of arterial obstruction is associated with resolution of clinical symptoms.

Thirty-one patients were given 2 dysautonomia-designed questionnaires to assess changes in symptoms following operative intervention in 6 functional domains and underwent postoperative repeat abdominal ultrasound examinations.

Average follow-up after surgery was 22.4±14.8months. Self-assessed quality of health on a Likert scale (1-10 with 10 being normal) improved from 4.5±2.1 preoperatively to 5.3±2.4 postoperatively (P = not significant). Gastrointestinal symptoms of abdominal pain, nausea, and vomiting improved in 63% (P=.007), 53% (P=.040), and 62% (P=.014) of patients, respectively. Cardiovascular symptoms of dizziness, syncope, chest pain, and pa and vomiting. Despite these encouraging data, many patients with MALS and OI continue to have an impaired quality of health.Anti-CRISPRs are protein inhibitors of CRISPR-Cas systems. They are produced by phages and other mobile genetic elements to evade CRISPR-Cas-mediated destruction. Anti-CRISPRs are remarkably diverse in sequence, structure, and functional mechanism; thus, structural and mechanistic investigations of anti-CRISPRs continue to yield exciting new insights. In this study, we used nuclear magnetic resonance (NMR) spectroscopy to determine the solution structure of AcrIE2, an anti-CRISPR that inhibits the type I-E CRISPR-Cas system of Pseudomonas aeruginosa. Guided by the structure, we used site-directed mutagenesis to identify key residues that are required for AcrIE2 function. Using affinity purification experiments, we found that AcrIE2 binds the type I-E CRISPR-Cas complex (Cascade). In vivo transcriptional assays, in which Cascade was targeted to promoter regions, demonstrated that Cascade still binds to DNA in the presence of AcrIE2. This is the first instance of a type I anti-CRISPR that binds to a CRISPR-Cas complex but does not prevent DNA-binding. Another unusual property of AcrIE2 is that the effect of CascadeAcrIE2 complex binding to promoter regions varied depending on the position of the binding site. Most surprisingly, CascadeAcrIE2 binding led to transcriptional activation in some cases rather than repression, which did not occur when Cascade alone bound to the same sites. We conclude that AcrIE2 operates through a distinct mechanism compared to other type I anti-CRISPRs. Metabolism inhibitor While AcrIE2 does not prevent Cascade from binding DNA, it likely blocks subsequent recruitment of the Cas3 nuclease to Cascade thereby preventing DNA cleavage.
