Contemporary issues are defined by people who share diverse and often strongly defended views about the topic. In Oregon, citizens are increasingly being asked or expected to participate in complex decisions that require a consensus. Rather than teach one professor's synthesis of a contemporary natural resource issue, faculty from six disciplines coach group process, interactive learning skills, and systems thinking as a way to address complex issues from multiple perspectives. Students learn by grappling with a natural resource issue of their choice within groups based on a diversity among majors, degree status, and gender. Students define situation (S), brainstorm new or different targets (T), and analyze two or more pathways (P), using an STP learning and action process. Exploring potential pathways involves defining possible consequences, stakeholder views, feasibility (ecological, social, economic, and political), and planning that includes expected behavior of the improved system over time. Students present their topics and improvements showing systemic relationships, systematic analysis, and integration of scientific facts and secondary data at midterm and during finals. Reflective learning is fostered throughout the course with prompted questions in a journal notebook. Grading criteria promote meaningful inquiry and participation in group process combined with integration of scientific facts and reflective learning.

Background: Intravenous (IV) sulfamethoxazole/trimethoprim (SMX/TMP) has been associated with hyponatremia in adults. Objective: The primary objective was to identify the number of patients with a serum sodium <135 mEq/L. Secondary objectives between the hyponatremic versus nonhyponatremic groups included demographic comparisons, median serum sodium concentrations, SMX/TMP cumulative dose, number of diuretics, and other medications causing hyponatremia. Methods: This was a retrospective study of children <18 years receiving IV SMP/TMX. Comparisons were conducted via Mann-Whitney-Wilcoxon and Mantel-Haenszel χ2 tests with an a priori P value <0.05. Results: Sixty-one patients received 66 total courses; 20 courses (30.3%) were associated with hyponatremia with a decrease in the median nadir serum sodium concentration of 133 and 138 mEq/L in the hyponatremic and nonhyponatremic groups, respectively ( P<0.001). The median age (interquartile range) was lower in the hyponatremic versus nonhyponatremic group, but this was not statistically significant: 0.6 (0.1-5.5) versus 3.9 (0.3-11.0) years; P=0.077. There was no significant difference in the median cumulative dose (mg/kg) between groups; P=0.104. In addition, there was a significant difference in the number of children in the hyponatremic versus nonhyponatremic groups receiving diuretics (16 [80.0%] vs 23 [50.0%], P=0.023) and other medications that cause hyponatremia (7 [35.0%] vs 5 [10.9%], P=0.034), respectively. Furosemide was noted to be the medication most associated with hyponatremia. Conclusion and Relevance: Approximately one-third administered IV SMX/TMP developed hyponatremia. Concomitant furosemide administration was one of the most common risk factors. Clinicians should be aware of this potential adverse event when initiating IV SMX/TMP in children.

Background: Few studies have compared clinical outcomes and medication use between obese and nonobese children in the pediatric intensive care unit (PICU). Objectives: The primary objective was to compare clinical outcomes including mortality, PICU length of stay (LOS), and mechanical ventilation (MV) requirement between obese and nonobese children. Secondary objectives included analysis of factors associated with these outcomes and medication use between groups. Methods: This retrospective study included children 2 to 17 years old admitted to the PICU over a 1-year time frame. Patients were categorized as obese, body mass index (BMI) ≥ 95th percentile, and nonobese (BMI < 95th percentile). Three binary regression models assessed the impact of obesity on clinical outcomes. Results: There were 834 admissions, with 22.1% involving obese children. There was no difference in mortality, MV requirement, or PICU LOS between groups. There were no associations with obesity and clinical outcomes found, but an association was noted for medication classes and receipt of continuous infusions on clinical outcomes. There was no difference noted in the median number (interquartile range [IQR]) of medications between obese and nonobese children, 8 (6-13) versus 9 (6-15), P = .38, but there was a difference in patients receiving a continuous infusion between obese and nonobese children, 24.4% versus 8.8%, P < .01. The 15 most used medications in both groups included analgesics, antimicrobials, corticosteroids, bronchodilators, and gastrointestinal agents. Conclusions: One-fifth of all admissions included obese children. Obesity was not associated with mortality, PICU LOS, and MV requirement, but the number of medication classes and continuous infusions were associated with these outcomes.
