Adverse events following emergent prehospital sedation of patients with behavioral emergencies: A retrospective cohort study.

Background: Patients presenting to emergency medical services (EMS) with behavioral emergencies may require emergent sedation to facilitate care, but concerns about sedation-related adverse events (AEs) exist. This study aimed to describe the frequency of AEs following emergent prehospital sedation with three types of sedative agents: ketamine, benzodiazepines and antipsychotics. Methods: This retrospective cohort study included patients ≥ 15 years who presented to 1031U.S. EMS agencies in calendar year 2019 with behavioral emergencies necessitating emergent prehospital sedation. Serious AEs (SAE) included cardiac arrest, invasive airway placement, and severe oxygen desaturation (<75%). Less-serious AEs included positive pressure ventilation, any oxygen desaturation (<90%), oropharyngeal or nasopharyngeal airway placement, and suctioning. The need for additional sedation was also assessed. Findings: Of 7973 patients, 1996 received ketamine; 4137 received a benzodiazepine; 1532 received an antipsychotic agent; and 308 received an indeterminant agent. Cardiac arrest occurred in 11 patients (0·1%) and any SAE occurred in 165 patients (2·1%). Invasive airway placement was more frequent with ketamine (40, 2·0%) compared with benzodiazepines (17, 0·4%) or antipsychotics (3, 0·2%). Oxygen desaturation below 75% also occurred more frequently with ketamine (51, 2·6%) than with benzodiazepines (52, 1·3%) or antipsychotics (14, 0·9%). Patients sedated with ketamine were less likely to require additional sedation. Propensity-matching to minimize potential confounding between patient condition, sedative choice and AEs did not meaningfully alter the results. Interpretation: Although SAEs were rare among patients receiving emergent prehospital sedation, prehospital clinicians should remain mindful of the potential risks and monitor patients closely. Funding: None.

A pilot study investigating the efficacy of brief, phone-based, behavioral interventions for burnout in graduate students.

OBJECTIVE: This pilot study tested the efficacy of two brief, phone-administered, behavioral interventions derived from behavioral activation in reducing burnout among doctoral students. METHODS: Sixty-six doctoral students demonstrating current high burnout were randomly assigned to one of three intervention conditions: (1) Reward: increasing pleasant, rewarding behaviors, (2) Approach: approaching important goals that they have been avoiding, or (3) Control: monitoring only. RESULTS: Results indicated that doctoral students treated with the approach intervention reported significantly lower burnout compared to participants in the control condition immediately after the intervention and at a 1-week follow-up. Results also suggested that students in the approach intervention also reported higher well-being compared to students in the control condition. CONCLUSION: These findings suggest that this approach intervention is an effective treatment for school burnout for doctoral students that can be delivered remotely through phone and web technology.

Development of a Binary End-of-Event Outcome Indicator for the NEMSIS Public Release Research Dataset.

INTRODUCTION: Emergency department and hospital discharge status are available for less than 2% of events recorded in the National EMS Information System (NEMSIS) Public Release Research dataset. The purpose of this project was to develop a binary ("dead" vs. "alive") end-of-event outcome indicator for the NEMSIS dataset. METHODS: The data dictionary for the Version 3 NEMSIS dataset was evaluated to identify elements and codes providing information about a patient's end-of-event status-defined as the point at which EMS providers stopped providing care for an encountered patient, whether at the scene of the event or the transport destination. Those element and code combinations were then used to test the criteria using the NEMSIS-2017 dataset. After revising the criteria based on the NEMSIS-2017 results, the final criteria were then applied to the 2018 NEMSIS dataset. To assess representativeness, the characteristics of events with a determinable outcome were compared to those of the entire dataset. To assess accuracy, the end-of-event indicator was compared with the final reported outcome for patients with a known emergency department disposition. RESULTS: Eighteen NEMSIS element and code combinations suggest a patient was likely "dead" at the end of EMS care, and 15 combinations suggest a patient was likely "alive" at the end of EMS care. A binary end-of-event outcome indicator could be determined for 13,045,887 (98.6%) of the 13,229,079 NEMSIS-2018 9-1-1 initiated ground EMS responses in which patient contact was established, and for 132,728 (89.1%) of the 148,963 events with documented cardiac arrest. The characteristics of the events with determinable end-of-event outcomes did not differ from those of the full dataset. Among patients with a known outcome, 99.6% of those with an "alive" end-of-event indicator were in fact alive at the time of emergency department disposition. CONCLUSION: A binary end-of-event outcome indicator can be determined for 98.6% of 9-1-1 initiated ground EMS scene responses and 89.1% of cardiac arrests included in the NEMSIS dataset. The events with a determinable outcome appear representative of the larger dataset and the end-of-event indicators are generally consistent with reported emergency department outcomes.

Lipid-lowering medications for children and adolescents.

As demonstrated by the 2011 publication of the National Heart, Lung, and Blood Institute Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, the information available regarding the treatment of pediatric lipid disorders has greatly expanded. HMG-CoA reductase inhibitor, or statin, therapy is now considered a first-line pharmacologic intervention for pediatric patients with severe dyslipidemias failing treatment with diet and exercise alone. Despite their ability to effectively reduce cholesterol levels, bile acid sequestrants continue to pose challenges for pediatric patients because of their unpalatability and are typically used as adjunctive therapy or for patients not able to tolerate statins. Fibric acid derivatives, as a class of medications, not only lack a Food and Drug Administration (FDA)-approved agent, but also continue to lack significant pediatric safety and efficacy data. Niacin, a potential adjunct therapy, lacks FDA approval for pediatric patients and is plagued by significant adverse effects making it an unlikely therapy option for pediatric patients. Ezetimibe provides clinicians with an alternative adjunct therapy option when synergistically paired with an HMG-CoA reductase inhibitor or it can be used as monotherapy for patients intolerant to statins and bile acid sequestrants. Finally, despite several marketed formulations, omega-3 fish oils currently lack FDA approval in pediatric patients and have failed to demonstrate statistically significant lipid lowering in pediatric and adolescent patients. Although recent years have witnessed a dramatic increase in data available for the use of lipid-lowering medications for pediatric patients, long-term study data are still generally lacking and continues to present an active focus of research.

The role of dietary fatty acids in predicting myocardial structure in fat-fed rats.

BACKGROUND: Obesity increases the risk for development of cardiomyopathy in the absence of hypertension, diabetes or myocardial ischemia. Not all obese individuals, however, progress to heart failure. Indeed, obesity may provide protection from cardiovascular mortality in some populations. The fatty acid milieu, modulated by diet, may modify obesity-induced myocardial structure and function, lending partial explanation for the array of cardiomyopathic phenotype in obese individuals. METHODS: Adult male Sprague-Dawley rats were fed 1 of the following 4 diets for 32 weeks: control (CON); 50% saturated fat (SAT); 40% saturated fat + 10% linoleic acid (SAT+LA); 40% saturated fat + 10% α-linolenic acid (SAT+ALA). Serum leptin, insulin, glucose, free fatty acids and triglycerides were quantitated. In vivo cardiovascular outcomes included blood pressure, heart rate and echocardiographic measurements of structure and function. The rats were sacrificed and myocardium was processed for fatty acid analysis (TLC-GC), and evaluation of potential modifiers of myocardial structure including collagen (Masson's trichrome, hydroxyproline quantitation), lipid (Oil Red O, triglyceride quantitation) and myocyte cross sectional area. RESULTS: Rats fed SAT+LA and SAT+ALA diets had greater cranial LV wall thickness compared to rats fed CON and SAT diets, in the absence of hypertension or apparent insulin resistance. Treatment was not associated with changes in myocardial function. Myocardial collagen and triglycerides were similar among treatment groups; however, rats fed the high-fat diets, regardless of composition, demonstrated increased myocyte cross sectional area. CONCLUSIONS: Under conditions of high-fat feeding, replacement of 10% saturated fat with either LA or ALA is associated with thickening of the cranial LV wall, but without concomitant functional changes. Increased myocyte size appears to be a more likely contributor to early LV thickening in response to high-fat feeding. These findings suggest that myocyte hypertrophy may be an early change leading to gross LV hypertrophy in the hearts of "healthy" obese rats, in the absence of hypertension, diabetes and myocardial ischemia.

A naturalistic study of the associations between changes in alcohol problems, spiritual functioning, and psychiatric symptoms.

The study evaluated how spiritual and religious functioning (SRF), alcohol-related problems, and psychiatric symptoms change over the course of treatment and follow-up. Problem drinkers (n = 55, including 39 males and 16 females) in outpatient treatment were administered questionnaires at pretreatment, posttreatment, and follow up, which assessed two aspects of SRF (religious well-being and existential well-being), two aspects of alcohol misuse (severity and consequences), and two aspects of psychiatric symptoms (depression and anxiety). Significant improvements in SRF, psychiatric symptoms and alcohol misuse were observed from pretreatment to follow-up. Although SRF scores were significantly correlated with psychiatric symptoms at all three time points, improvement in the former did not predict improvement in the latter. When measured at the same time points, SRF scores were not correlated with the measures of alcohol misuse. However, improvement in SRF (specifically in existential well-being) over the course of treatment was predictive of improvement in the alcohol misuse measures at follow-up. These results suggest that the association between SRF, emotional problems, and alcohol misuse is complex. They further suggest that patients who improve spiritual functioning over the course of treatment are more likely to experience improvement in drinking behavior and alcohol-related problems after treatment has ended.
