Given the magnitude and seriousness of PICC complications, clinicians should reconsider the practice of treating otherwise healthy children with acute osteomyelitis with prolonged intravenous antibiotics after hospital discharge when an equally effective oral alternative exists.
An imbalance between triacylglycerol synthesis and breakdown is necessary for the development of obesity. The direct precursor for triacylglycerol biosynthesis is ␣-glycerol phosphate, which can have glycolytic and glyceroneogenic origins. We present a technique for determining the relative glyceroneogenic contribution to triacylglyceride glycerol by labeling the glycerol moiety with 2 H 2 O. The number of hydrogen atoms (n) incorporated from H 2 O into C-H bonds reflects the metabolic source of ␣-glycerol phosphate and can be calculated by combinatorial analysis of the distribution of mass isotopomers in triacylglyceride glycerol. Three physiological settings with potential effects on glyceroneogenesis and glycolysis were studied in rodents. Adipose tissue acylglyceride glycerol in mice fed a low carbohydrate diet had significantly higher values of n than in mice fed a high carbohydrate diet, suggesting an increased contribution from glyceroneogenesis of from 17 to 50% on the low carbohydrate diet. Similarly, mice administered rosiglitazone had a significant relative increase in glyceroneogenesis (from 17 to 53%), indicated by an increase in adipose acylglyceride glycerol n. Fructose infusion in overnight fasted rats rapidly lowered plasma triacylglyceride glycerol n, reflecting a decreased contribution from glyceroneogenesis (from 66 to 34%) presumably because of increased glycolytic input. In conclusion, we demonstrate that the number of C-H atoms derived from cellular H 2 O in triacylglyceride glycerol is an informative indicator of ␣-glycerol phosphate origin and, ultimately, triacylglycerol metabolism. Under certain physiological conditions, glyceroneogenesis can be upregulated in adipose (e.g. low carbohydrate diet) or down-regulated in liver (e.g. fructose infusion). Additionally, stimulation of glyceroneogenesis by rosiglitazone in adipose tissue may be an important factor in the antilipolytic actions of thiazolidinediones.
Treatment failure rates between PICC and oral antibiotics did not differ. Children with complicated pneumonia should preferentially receive oral antibiotics at discharge when effective oral options are available.
IMPORTANCE National guidelines recommend against continuous pulse oximetry use for hospitalized children with bronchiolitis who are not receiving supplemental oxygen, yet guidelinediscordant use remains high. OBJECTIVES To evaluate deimplementation outcomes of educational outreach and audit and feedback strategies aiming to reduce guideline-discordant continuous pulse oximetry use in children hospitalized with bronchiolitis who are not receiving supplemental oxygen. DESIGN, SETTING, AND PARTICIPANTS A nonrandomized clinical single-group deimplementation trial was conducted in 14 non-intensive care units in 5 freestanding children's hospitals and 1 community hospital from December 1, 2019, through March 14, 2020, among 847 nurses and physicians caring for hospitalized children with bronchiolitis who were not receiving supplemental oxygen. INTERVENTIONS Educational outreach focused on communicating details of the existing guidelines and evidence. Audit and feedback strategies included 2 formats: (1) weekly aggregate data feedback to multidisciplinary teams with review of unit-level and hospital-level use of continuous pulse oximetry, and (2) real-time 1:1 feedback to clinicians when guideline-discordant continuous pulse oximetry use was discovered during in-person data audits. MAIN OUTCOMES AND MEASURES Clinician ratings of acceptability, appropriateness, feasibility, and perceived safety were assessed using a questionnaire. Guideline-discordant continuous pulse oximetry use in hospitalized children was measured using direct observation of a convenience sample of patients with bronchiolitis who were not receiving supplemental oxygen. RESULTS A total of 847 of 1193 eligible clinicians (695 women [82.1%]) responded to a Likert scalebased questionnaire (71% response rate). Most respondents rated the deimplementation strategies of education and audit and feedback as acceptable (education, 435 of 474 [92%]; audit and feedback, 615 of 664 [93%]), appropriate (education, 457 of 474 [96%]; audit and feedback, 622 of 664 [94%]), feasible (education, 424 of 474 [89%]; audit and feedback, 557 of 664 [84%]), and safe (803 of 847 [95%]). Sites collected 1051 audit observations (range, 47-403 per site) on 709 unique patient admissions (range, 31-251 per site) during a 3.5-month period of continuous pulse oximetry use in children with bronchiolitis not receiving supplemental oxygen, which were compared with 579 observations (range, 57-154 per site) from the same hospitals during the baseline 4-month period (prior season) to determine whether the strategies were associated with a reduction in use. (continued) Key Points Question Are audit and feedback strategies and educational outreach associated with clinician perceptions of the feasibility, acceptability, appropriateness, and safety of continuous pulse oximetry use in children hospitalized with bronchiolitis who are not receiving supplemental oxygen (guideline-discordant use)? Findings In this 6-hospital single-group nonrandomized clinical trial, 847 nurses and physicians highl...
IMPORTANCE The American Academy of Pediatrics and the Centers for Disease Control and Prevention recommend waiting 3 to 5 days between the introduction of new complementary foods (solid foods introduced to infants <12 months of age), yet with advances in the understanding of infant food diversity, the guidance that pediatric practitioners are providing to parents is unclear. OBJECTIVE To characterize pediatric practitioner recommendations regarding complementary food introduction and waiting periods between introducing new foods. DESIGN, SETTING, AND PARTICIPANTS In this survey study, a 23-item electronic survey on complementary food introduction among infants was administered to pediatric health care professionals from February 1 to April 30, 2019. Responses were described among the total sample and compared among subgroups. Survey invitations were emailed to 2215 members of the Illinois Chapter of the American Academy of Pediatrics and the national American Academy of Pediatrics' Council on Early Childhood. Participants were required to be primary medical practitioners, such as physicians, resident physicians, or nurse practitioners, providing pediatric care to infants 12 months or younger. MAIN OUTCOMES AND MEASURES The main outcome measures were recommendations on age of complementary food introduction and waiting periods between the introduction of new foods. Categorical survey items were reported as numbers (percentages) and 95% CIs. Means (SDs) were used to describe continuous survey items. RESULTS The survey was sent to 2215 practitioners and completed by 604 (response rate, 27.3%). Of these respondents, 41 were excluded because they did not provide care for infants or pediatric patients. The final analyses included responses from 563 surveys. Of these, 454 pediatricians (80.6%), 85 resident physicians (15.1%), and 20 nurse practitioners (3.6%) completed the survey. Only 217 practitioners (38.6%; 95% CI, 34.1%-44.6%) recommended waiting 3 days or longer between food introduction; 259 practitioners (66.3%; 95% CI, 61.4%-70.8%) recommended waiting that amount of time for infants at risk for food allergy development (P = .02). A total of 264 practitioners (46.9%; 95% CI, 42.8%-51.0%) recommended infant cereal as the first food, and 226 practitioners (40.1%; 95% CI, 36.1%-44.2%) did not recommend a specific order. A total of 268 practitioners (47.6%; 95% CI, 43.5%-51.7%) recommended food introduction at 6 months for exclusively breastfed (EBF) infants, and 193 (34.3%; 95% CI, 30.5%-38.3%) recommended food introduction at 6 months for non-EBF infants (P < .001); 179 practitioners (31.8%; 95% CI, 28.1%-35.8%) recommended food introduction at 4 months for EBF infants, and 239 practitioners (42.5%; 95% CI, 38.4%-46.6%) recommended food introduction at 4 months for non-EBF infants (P < .001). A need for additional training on complementary food introduction was reported by 310 practitioners (55.1%; 95% CI, 50.9%-59.1%).
BACKGROUND Recent studies report an increasing incidence of Clostridium difficile infections (CDIs) in children and suggest that CDIs may occur outside known populations at risk. OBJECTIVE To identify clinical factors associated with CDI in a hospitalized pediatric population. METHODS A retrospective case‐control study was conducted with C difficile cases (CD) and controls (CTLs) in hospitalized children over a 2‐year period. CDs (N = 134) and 2:1 age‐matched CTLs (N = 274) with diarrheal illness were evaluated. RESULTS CDs and CTLs were similar in gender and race. Watery diarrhea was the most common type of diarrhea in CDs and CTLs. Immunodeficiency (46% vs 6%; P < 0.001), gastrointestinal (GI) disease (31% vs 18%; P = 0.005), and proton pump inhibitor (PPI) use (22% vs 7%; P < 0.001) were more frequent in CDs. Of CDs, 30% were defined as community acquired. Bloody diarrhea was more frequent in community‐acquired CD (28% vs 4% P < 0.001); however, other clinical variables were not statistically different. No antibiotic exposure, recent hospitalization, prolonged hospitalization, or past history of CDI existed in 8% of CDs. Multivariate logistic regression demonstrated that antibiotic use (odds ratio [OR]: 2.80, P = 0.001), recent hospitalization (OR: 2.33, P = 0.007), and immunodeficiency (OR: 6.02, P < 0.001) were significantly associated with cases when controlling for PPI use, having GI disease, and history of abdominal surgery. CONCLUSIONS Clinical history is of greater value than symptoms in distinguishing CD, with immunodeficiency having the strongest association. An important percentage of CDs did not have any risk factors, confirming concerns that CDIs do occur in otherwise low‐risk pediatric populations Journal of Hospital Medicine 2014;9:94–98. © 2013 Society of Hospital Medicine
