The aim of this study was to investigate asthma management policies and protocols in Bronx, New York, public elementary schools in light of the National Heart, Lung, and Blood Institute (NHLBI) Resolution on Asthma Management in Schools. An anonymous survey was conducted in November 2001 of principals, teachers, counselors, and nurses at five Bronx elementary schools. The response rate was 62%, and the majority of respondents (84%) were teachers; 51% of respondents learned of a student's asthma only through informal conversation with the student or parent, 28% said they were usually not informed of a student's asthma status, and only 10% learned of a child's asthma through existing school protocols; 21% of respondents did not know whom in the school was responsible for supervising the health needs of children with asthma, and 30% did not know how asthma inhalers were supposed to be handled at their school. Only 1.6% of teachers were "very familiar" with Board of Education asthma policies. The results are interpreted as showing poor adherence to the NHLBI recommendations. They also reflect a lack of consistent strategies for communication of a child's asthma diagnosis and for management of the disease in the schools. Ongoing efforts to improve asthma management in public schools through teacher education and policy development should be supported and evaluated for outcomes in teacher knowledge and student health.

Objectives: With decreasing mortality in PICUs, a growing number of survivors experience long-lasting physical impairments. Early physical rehabilitation and mobilization during critical illness are safe and feasible, but little is known about the prevalence in PICUs. We aimed to evaluate the prevalence of rehabilitation for critically ill children and associated barriers. Design: National 2-day point prevalence study. Setting: Eighty-two PICUs in 65 hospitals across the United States. Patients: All patients admitted to a participating PICU for greater than or equal to 72 hours on each point prevalence day. Interventions: None. Measurements and Main Results: The primary outcome was prevalence of physical therapy– or occupational therapy–provided mobility on the study days. PICUs also prospectively collected timing of initial rehabilitation team consultation, clinical and patient mobility data, potential mobility–associated safety events, and barriers to mobility. The point prevalence of physical therapy– or occupational therapy–provided mobility during 1,769 patient-days was 35% and associated with older age (adjusted odds ratio for 13–17 vs < 3 yr, 2.1; 95% CI, 1.5–3.1) and male gender (adjusted odds ratio for females, 0.76; 95% CI, 0.61–0.95). Patients with higher baseline function (Pediatric Cerebral Performance Category, ≤ 2 vs > 2) less often had rehabilitation consultation within the first 72 hours (27% vs 38%; p < 0.001). Patients were completely immobile on 19% of patient-days. A potential safety event occurred in only 4% of 4,700 mobility sessions, most commonly a transient change in vital signs. Out-of-bed mobility was negatively associated with the presence of an endotracheal tube (adjusted odds ratio, 0.13; 95% CI, 0.1–0.2) and urinary catheter (adjusted odds ratio, 0.28; 95% CI, 0.1–0.6). Positive associations included family presence in children less than 3 years old (adjusted odds ratio, 4.55; 95% CI, 3.1–6.6). Conclusions: Younger children, females, and patients with higher baseline function less commonly receive rehabilitation in U.S. PICUs, and early rehabilitation consultation is infrequent. These findings highlight the need for systematic design of rehabilitation interventions for all critically ill children at risk of functional impairments.

Carbon monoxide (CO) inhalation often leads to cardiac dysfunction, dysrhythmias, ischemia, infarction, and death. However, the underlying mechanism of CO toxicity is poorly understood. We hypothesize that inhaled CO interrupts myocardial oxidative phosphorylation by decreasing the activity of myocardial cytochrome oxidase (CcOX), the terminal oxidase of the electron transport chain. Male C57Bl6 mice were exposed to either 1000 ppm (0.1%) CO or air for 3 h. Cardiac ventricles were harvested and mitochondria were isolated. CcOX kinetics and heme aa(3) content were measured. V(max), K(m), and turnover number were determined. Levels of CcOX subunit I message and protein were evaluated. Carboxyhemoglobin (COHb) levels were measured and tissue hypoxia was assessed with immunohistochemistry for pimonidazole hydrochloride. CO significantly decreased myocardial CcOX activity and V(max) without altering K(m). Heme aa(3) content and CcOX I protein levels significantly decreased following CO exposure while enzyme turnover number and CcOX I mRNA levels remained unchanged. CO exposure increased COHb levels without evidence of tissue hypoxia as compared to sham and hypoxic controls. Decreased CcOX activity following CO inhalation was likely due to decreased heme aa(3) and CcOX subunit I content. Importantly, myocardial CcOX impairment could underlie CO induced cardiac dysfunction.

Background: The Accreditation Council for Graduate Medical Education (ACGME) requires evaluation of residents'communication skills. These evaluations should involve assessments from a variety of persons with different perspectives and opportunities to observe resident behavior. Our objectives with this study were to determine if parents, nurses, and physicians significantly differed in their ratings of residents' communication skills; to ascertain the degree of association between these evaluations and ACGME milestone data; and to elicit feedback from residents about the specificity and usefulness of this type of evaluation compared to the evaluations they were typically provided. Methods: During the 2016-2017 academic year, parents of patients ready for discharge, nurses, and attending physicians completed evaluations of resident communication skills. A repeated measures multivariate analysis of variance compared communication skills scores across the 3 groups of raters. Resident ACGME milestone ratings for interpersonal and communication skills were correlated with the communication skills evaluations. Residents rated the specificity and usefulness of the 360-degree evaluations. Results: Parents rated residents' communication skills significantly higher than nurses and physicians rated them. We found no significant difference between the nurse and physician ratings. A significant correlation was found between resident ratings by physicians and ACGME milestone data. Residents found the feedback from these evaluations to be more specific and useful in delineating their communication strengths and weaknesses than typical milestone feedback. Conclusion: Parents added a unique perspective about residents' communication and should be included in resident evaluation when feasible. Residents appreciated the specificity and usefulness of the evaluation instrument.
