Thoracic ultrasound may improve paramedic diagnostic and management accuracy in undifferentiated respiratory distress.

Objectives: Patients with chronic obstructive pulmonary disease (COPD) and congestive heart failure (CHF) exacerbations present with similar history and physical examination findings. This complicates both the diagnostic process and the creation of appropriate treatment plans for patients presenting in respiratory distress, particularly in the prehospital setting. Thoracic point-of-care-ultrasound (POCUS) may increase diagnostic accuracy; however, its potential to improve patient management by emergency medical services clinicians is unknown. We aimed to determine whether a brief thoracic POCUS educational intervention would improve prehospital diagnostic accuracy and treatment plans for patients with COPD and CHF exacerbations. Methods: In this prospective pre-/post-study, paramedics completed a thoracic POCUS training program. The pre-test presented history and physical examination data for 10 patients and asked paramedics to diagnose each patient with COPD or CHF exacerbation and to select the appropriate treatment(s). The post-test asked paramedics to interpret ultrasound images in addition to selecting diagnosis and treatment(s). Pre-post differences in average cumulative diagnostic and management accuracy were analyzed using paired two-tailed t-tests. Results: Thirty-three paramedics participated in the study. At baseline, paramedics selected the accurate patient diagnosis and treatment(s) 73% and 60% of the time, respectively. On the post-test, diagnostic accuracy improved by 17% (95% confidence interval [CI]: 11-24, p < 0.001) and appropriate treatment selection improved by 23% (95% CI: 16-28, p < 0.001). Paramedics correctly interpreted ultrasound images 90% of the time. Conclusion: Effective training of paramedics to recognize the clinical scenario of undifferentiated respiratory distress and their associated thoracic ultrasound images may lead to improved treatment plans.

Effects of Acute Yohimbine Hydrochloride Supplementation on Repeated Supramaximal Sprint Performance.

The purpose of this study was to examine the effects of a single acute dose of yohimbine hydrochloride on repeated anaerobic sprint ability. Physically active females (n = 18) completed two separate repeated supramaximal sprint trials each with a different single-dose treatment: placebo (PL; gluten-free corn starch) or yohimbine hydrochloride (YHM; 2.5 mg). For each trial, participants consumed their respective treatment 20 min before exercise. Following a warm-up, participants completed 3 × 15 s Wingate anaerobic tests (WAnTs) separated by 2 min of active recovery. A capillary blood sample was obtained pre- and immediately post-exercise to measure blood concentrations of lactate (LA), epinephrine (EPI), and norepinephrine (NE). Heart rate (HR) and rate of perceived exertion (RPE) were measured following each WAnT. Findings showed that mean power (p < 0.001; η2 = 0.024), total work (p < 0.001; η2 = 0.061), and HR (p < 0.001; η2 = 0.046), were significantly higher with YHM supplementation versus PL. Fatigue index (p < 0.001; η2 = 0.054) and post-exercise LA (p < 0.001; d = 1.26) were significantly lower with YHM compared to PL. YHM resulted in significantly higher EPI concentrations versus PL (p < 0.001; η2 = 0.225) pre- and post-exercise while NE only increased as a function of time (p < 0.001; η2 = 0.227) and was unaffected by treatment. While RPE increased after each WAnT, no differences between treatments were observed (p = 0.539; η2 < 0.001). Together, these results suggest that acute YHM ingestion imparts ergogenic benefits which may be mediated by lower blood LA and fatigue concomitantly occurring with blood EPI increases. Thus, YHM may improve sprint performance although more mechanistic study is warranted to accentuate underlying processes mediating performance enhancement.

Scoping Review: Medical Education Interventions Optimizing Social Workers in the Emergency Department.

INTRODUCTION: As the significance of social workers (SW) in improving healthcare delivery in the emergency department (ED) continues to expand, emergency physicians will increasingly be expected to effectively partner with SWs in both academic and community settings. In this scoping review we sought to provide evidence-based recommendations for effective emergency clinician educational interventions on how to incorporate SWs in the ED to address health-related social needs while also identifying directions for future research. METHODS: We conducted a systematic literature review of publications in PubMed, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and APA PsycINFO. A search strategy was designed in accordance with Peer Review of Electronic Search Strategies (PRESS) guidelines. Using the scoping review framework by Arksey and O'Malley, we applied consensus-based inclusion and exclusion criteria to guide study selection. A Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) flow chart delineating the selection process was generated using Covidence. RESULTS: Our search strategy identified nine qualifying articles for further analysis out of an initial sample of 2,119 articles. Of the nine articles that underwent full text review, 89% (8/9) evaluated a short educational didactic with or without a hands-on component to reinforce learning. Barriers to successful implementation of curricula discussed in all articles included time constraints, lack of buy-in from clinical faculty, lack of knowledge of appropriate referral sources once a problem is identified, and perceived distraction of the training from more standard clinical topics. Facilitators of curricula implementation and training success included the presence of a pre-existing and structured weekly conference schedule, ability to complete the training in a relatively short time frame or during intern orientation, presence of simulation resources, and residents' overall perceived interest in the topics. CONCLUSION: Ultimately, we found that interdisciplinary learning with SWs is generally well received by participants, and we offer various suggestions on incorporation into student and resident education. Moving forward, we recommend that a standardized curriculum of working with SWs be developed using didactic sessions, simulation, and/or direct observation with feedback.

Meaningful work and mental health: job satisfaction as a moderator.

BACKGROUND: Depression, anxiety and stress are common problems for modern workers. Although having meaningful work, or work that is significant, facilitates personal growth, and contributes to the greater good, has been linked to better mental health, people's work might also need to be satisfying or enjoyable to improve outcomes. AIMS: The purpose of the present study was to examine meaningful work's relation to mental health (i.e. depression, anxiety and stress) and investigate job satisfaction as a moderator of this relation. METHODS: The study hypotheses were tested with a large, diverse sample recruited from an online source. RESULTS: Partially supporting hypotheses, when controlling for job satisfaction, meaningful work negatively correlated with depression but did not have a significant relation with anxiety and stress. Similarly, job satisfaction negatively predicted depression and stress. Furthermore, the relations between meaningful work and both anxiety and stress were moderated by job satisfaction. Specifically, only people perceiving their work as meaningful and satisfying reported less anxiety and stress. CONCLUSIONS: Although continued research is needed, employers and employees may have to target both the meaningfulness and job satisfaction to address the issues of stress and anxiety among working adults.
