RESUMEN
The use of a bougie, a flexible endotracheal tube introducer, has been proposed to optimize first-attempt success in emergency department intubations. We aimed to evaluate the available evidence on the association of bougie use in the first attempt and success in tracheal intubations. This was a systematic review and meta-analysis of studies that evaluated first-attempt success between adults intubated with a bougie versus without a bougie (usually with a stylet) in all settings. Manikin and cadaver studies were excluded. A medical librarian searched Ovid Cochrane Central, Ovid Embase, Ovid Medline, Scopus, and Web of Science for randomized controlled trials and comparative observational studies from inception to June 2023. Study selection and data extraction were done in duplicate by 2 independent reviewers. We conducted a meta-analysis with random-effects models, and we used GRADE to assess the certainty of evidence at the outcome level. We screened a total of 2,699 studies, and 133 were selected for full-text review. A total of 18 studies, including 12 randomized controlled trials, underwent quantitative analysis. In the meta-analysis of 18 studies (9,151 patients), bougie use was associated with increased first-attempt intubation success (pooled risk ratio [RR] 1.11, 95% confidence interval [CI] 1.06 to 1.17, low certainty evidence). Bougie use was associated with increased first-attempt success across all analyzed subgroups with similar effect estimates, including in emergency intubations (9 studies; 8,070 patients; RR 1.11, 95% CI 1.05 to 1.16, low certainty). The highest point estimate favoring the use of a bougie was in the subgroup of patients with Cormack-Lehane III or IV (5 studies, 585 patients, RR 1.60, 95% CI 1.40 to 1.84, moderate certainty). In this meta-analysis, the bougie as an aid in the first intubation attempt was associated with increased success. Despite the certainty of evidence being low, these data suggest that a bougie should probably be used first and not as a rescue device in emergency intubations.

OBJECTIVE: Falls in older adults correlate with heightened morbidity and mortality. Assessing fall risk in the emergency department (ED) not only aids in identifying candidates for prevention interventions but may also offer insights into overall mortality risk. We sought to examine the link between fall risk and 30-day mortality in older ED adults. METHODS: Observational cohort study of adults aged ≥ 75years who presented to an academic ED and who were assessed for fall risk using the Memorial Emergency Department Fall Risk Assessment Tool (MEDFRAT), a validated, ED-specific screening tool. The fall risk was classified as low (0-2 points), moderate (3-4 points), or high (≥5) risk. The primary outcome was 30-day mortality. Hazard ratios (HR) with 95% confidence intervals (CIs) were calculated. RESULTS: A total of 941 patients whose fall risk was assessed in the ED were included in the study. Median age was 83.7 years; 45.6% were male, 75.6% lived in private residences, and 62.7% were admitted. Mortality at 30 days among the high fall risk group was four times that of the low fall risk group (11.8% vs 3.1%; HR 4.00, 95% CI 2.18 to 7.34, p < 0.001). Moderate fall risk individuals had nearly double the mortality rate of the low-risk group (6.0% vs 3.1%), but the difference was not statistically significant (HR 1.98, 95% CI 0.91 to 4.32, p = 0.087). CONCLUSION: ED fall risk assessments are linked to 30-day mortality. Screening may facilitate the stratification of older adults at risk for health deterioration.

PURPOSE: To examine the safety and effectiveness of benzodiazepines (BZD) as compared to antipsychotics for the management of acute agitation in older adults in the emergency department (ED). BASIC PROCEDURES: Retrospective observational cohort study of 21 EDs across four states in the US, including adults ≥60 years old who received either BZD or antipsychotics for acute agitation in the ED and subsequently were admitted to the hospital. Safety was measured as presence of adverse events: respiratory depression, cardiovascular effects, extrapyramidal side effects, or a fall during hospitalization. Effectiveness was measured as indicators of treatment failure: need for additional medication, one-to-one observation, or physical restraints following initial medication administration. Proportions and odds ratios with 95% confidence intervals (CI) were calculated. Univariable and multivariable logistic regression were used to assess the association between potential risk factors and for efficacy and safety endpoints. MAIN FINDINGS: A total of 684 patients were included (63.9% received a BZD and 36.1% an antipsychotic). There was no difference in the incidence of adverse events between groups (20.6% vs 14.6%, difference 6.0%, 95% CI -0.2% to 11.8%), but there was a higher intubation rate in the BZD group (2.7% vs 0.4%, difference 2.3%). There were more treatment failures in the antipsychotic group for the composite primary efficacy endpoint (94.3% vs 87.6%, difference 6.7%, 95% CI 2.5% to 10.9%). This appears to have been driven by the need for 1:1 observation; sensitivity analysis excluding 1:1 observation in the composite outcome demonstrated no significant difference with a failure rate of 38.5% in the antipsychotic group and 35.2% in the benzodiazepine group. PRINCIPAL CONCLUSIONS: Overall there are high rates of treatment failure among agitated older adults receiving pharmacological treatment for agitation in the emergency department. The optimal selection of pharmacological treatment for agitation in older adults should be made considering patient-specific factors that could increase the risk of adverse effects or treatment failure.

STUDY OBJECTIVE: To evaluate the association between delirium and subsequent short-term mortality in geriatric patients presenting to the emergency department (ED). METHODS: This was an observational cohort study of adults age ≥75 years who presented to an academic ED and were screened for delirium during their ED visit. The Delirium Triage Screen followed by the Brief Confusion Assessment Method were used to ascertain the presence of delirium. In-hospital, 7-day, and 30-day mortality were compared between patients with and without ED delirium. Odds ratios with 95% confidence intervals (CIs) were calculated through logistic regression after adjusting for confounders including age, sex, history of dementia, ED disposition, and acuity. RESULTS: A total of 967 ED visits were included for analysis among which delirium was detected in 107 (11.1%). The median age of the cohort was 83 years (IQR 79, 88), 526 (54.4%) were female, 285 (29.5%) had documented dementia, and 171 (17.7%) had a high acuity Emergency Severity Index triage level 1 or 2. During the hospitalization, 5/107 (4.7%) of those with delirium and 4/860 (0.5%) of those without delirium died. Within 7 days of ED departure, 6/107 (5.6%) of those with delirium and 6/860 (0.7%) of those without delirium died (unadjusted OR 8.46, 95% CI 2.68-26.71). Within 30 days, 18/107 (16.8%) of those with delirium and 37/860 (4.3%) of those without delirium died (unadjusted OR 4.50, 95% CI 2.46-8.23). ED delirium remained associated with higher 7-day (adjusted OR 5.23, 95% CI 1.44-19.05, p = 0.008) and 30-day mortality (adjusted OR 2.82, 95% CI 1.45-5.46, p = 0.002). CONCLUSION: Delirium is an important prognostic factor that ED clinicians and nurses must be aware of to optimize delirium prevention, management, disposition, and communication with patients and families.

OBJECTIVE: To assess the QTc interval variation after low-dose droperidol in a population of undifferentiated, stable, and non-agitated patients receiving droperidol in the emergency department. METHODS: Prospective cohort study of patients aged ≥12 years of age who received low-dose droperidol (≤ 2.5 mg) for indications other than acute behavioral disturbances. QTc intervals were monitored in real-time during pre-specified observation periods in the ED. Primary outcome was variation of QTc interval after droperidol administration, defined as the maximum delta (change) of QTc interval. Other outcomes included proportion of patients with a QTc ≥ 500 ms after droperidol, delta ≥ +60 ms, and incidence of clinical adverse events. Patients were monitored up to 30 min after IV bolus and up to 46 min after infusion. RESULTS: A total of 68 patients were included (mean age 42.1 years, 66.2% females). The median dose of droperidol was 1.875 mg (range 0.625 mg, 2.5 mg) and 94.1% received droperidol for headache management. Most patients received droperidol as a 2-min bolus (n = 41, 60.3%). The mean maximum delta of QTc interval after droperidol across all 68 patients was +29.9 ms (SD 15). A total of 12 patients (17.6%) experienced a QTc interval ≥ 500 ms during the observation period after droperidol, and 3 patients (4.4%) had a delta QTc ≥ +60 ms. There were no serious arrhythmias, such as TdP, or deaths among the 68 participants in this study (0/68). However, 13.2% (n = 9) had at least one non-serious adverse event including restlessness and/or anxiety. CONCLUSION: The QTc interval slightly increased after droperidol administration, but these prolongations were brief, mostly below 500 msec and did not lead to serious arrhythmias. The yield of continuous cardiac monitoring in patients receiving low doses of droperidol is likely low.

OBJECTIVES: To evaluate the short-term mortality of adult patients presenting to the emergency department (ED) with altered mental status (AMS) as compared to other common chief complaints. METHODS: Observational cohort study of adult patients (age ≥ 40) who presented to an academic ED over a 1-year period with five pre-specified complaints at ED triage: AMS, generalized weakness, chest pain, abdominal pain, and headache. Primary outcomes included 7 and 30-day mortality. Hazard ratios (HR) were calculated with 95% confidence intervals (CI) using Cox proportional hazards models adjusted for age, acuity level, and comorbidities. RESULTS: A total of 9850 ED visits were included for analysis from which 101 (1.0%) and 295 (3.0%) died within 7 and 30 days, respectively. Among 683 AMS visits, the 7-day mortality rate was 3.2%. Mortality was lower for all other chief complaints, including generalized weakness (17/1170, 1.5%), abdominal pain (32/3609, 0.9%), chest pain (26/3548, 0.7%), and headache (4/840, 0.5%). After adjusting for key confounders, patients presenting with AMS had a significantly higher risk of death within 7 days of ED arrival than patients presenting with chest pain (HR 3.72, 95% CI 2.05 to 6.76, p < .001). Similarly, we found that patients presenting with AMS had a significantly higher risk of dying within 30 days compared to patients with chest pain (HR 3.65, 95% CI 2.49 to 5.37, p < .001), and headache (HR 2.09, 95% CI 1.09 to 4.01, p = .026). Differences were not statistically significant for comparisons with abdominal pain and generalized weakness, but confidence intervals were wide. CONCLUSION: Patients presenting with AMS have worse short-term prognosis than patients presenting to the ED with chest pain or headache. AMS may indicate an underlying brain dysfunction (delirium), which is associated with adverse outcomes and increased mortality.

STUDY OBJECTIVE: To evaluate the association between potential emergency department (ED)-based modifiable risk factors and subsequent development of delirium among hospitalized older adults free of delirium at the time of ED stay. METHODS: Observational cohort study of patients aged ≥75 years who screened negative for delirium in the ED, were subsequently admitted to the hospital, and had delirium screening performed within 48 h of admission. Potential ED-based risk factors for delirium included ED length of stay (LOS), administration of opioids, benzodiazepines, antipsychotics, or anticholinergics, and the placement of urinary catheter while in the ED. Odds ratios (OR) and mean differences (MD) with 95% confidence intervals (CIs) were calculated. RESULTS: Among 472 patients without delirium in the ED (mean age 84 years, 54.2% females), 33 (7.0%) patients developed delirium within 48 h of hospitalization. The ED LOS of those who developed delirium was similar to those who did not develop delirium (312.1 vs 325.6 min, MD -13.5 min, CI -56.1 to 29.0). Patients who received opioids in the ED were as likely to develop delirium as those who did not receive opioids (7.2% vs 6.9%: OR 1.04, CI 0.44 to 2.48). Patients who received benzodiazepines had a higher risk of incident delirium, the difference was clinically but not statistically significant (37.3% vs 6.5%, OR 5.35, CI 0.87 to 23.81). Intermittent urinary catheterization (OR 2.05, CI 1.00 to 4.22) and Foley placement (OR 3.69, CI 1.55 to 8.80) were associated with a higher risk of subsequent delirium. After adjusting for presence of dementia, only Foley placement in the ED remained significantly associated with development of in-hospital delirium (adjusted OR 3.16, CI 1.22 to 7.53). CONCLUSION: ED LOS and ED opioid use were not associated with higher risk of incident delirium in this cohort. Urinary catheterization in the ED was associated with an increased risk of subsequent delirium. These findings can be used to design ED-based initiatives and increase delirium prevention efforts.

Essential oils encapsulated in a polymeric matrix can be used as an alternative method to control fungi and mycotoxins. The essential oils were extracted by hydrodistillation and characterized by gas chromatography. The nanofibres were produced from poly (acid lactic) (PLA) containing essential oils by the Solution Blow Spinning method. The antifungal and antimicotoxygenic properties were evaluated against Aspergillus ochraceus and Aspergillus westerdijkiae by the fumigation method. Terpinen-4-ol (20·23%), sabinene (20·18%), 1·8-cineole (16·69%) and γ-terpinene (11·03%) were the principal compounds present in the essential oil from Alpinia speciosa, whereas citral (97·67%) was dominant from Cymbopogon flexuosus. Microscopy images showed that the addition of essential oils caused an increase in the diameter of the nanofibres. The infrared spectroscopy results indicated the presence of essential oils in the PLA nanofibres. Differential scanning calorimetry curves also indicated the existence of interactions between the essential oils and polymeric macromolecules through their plasticizing action. The hydrophobic character of nanofibres was revealed by the contact angle technique. An antifungal effect was observed, the mycelial growths (3·25-100%) and the synthesis of ochratoxin A (25·94-100%) were inhibited by the presence of the nanofibres. The results suggest that bioactive nanofibres hold promise for application to control toxigenic fungi.

Coffee (Coffea L.) is one of the main crops produced globally. Its contamination by the fungus Hemileia vastatrix Berkeley and Broome has been economically detrimental for producers. The objective of this work was to extract and characterize the essential oils from Eucalyptus citriodora Hook, Eucalyptus camaldulensis Dehn and Eucalyptus grandis Hill ex Maiden, produce and characterize nanoparticles containing these essential oils and evaluate the in vivo and in vitro antifungal activity of free and nanoencapsulated essential oils. The principal constituent of the essential oil from E. citriodora was citronellal; that from E. grandis was α-pinene; and that from E. camaldulensis was 1,8-cineol. The in vitro antifungal activity against the fungus H. vastatrix was 100% at a concentration of 1000 µl l-1 for all the oils and nanoparticles containing these natural products. The sizes of the nanoparticles produced with the essential oils from E. citriodora, E. camaldulensis and E. grandis were 402·13 nm, 275·33 nm and 328·5 nm, respectively, with surface charges of -11·8 mV, -9·24 mV and - 6·76 mV, respectively. Fourier transform infrared analyses proved that the encapsulation of essential oils occurred in the polymeric matrix of poly(ε-caprolactone). The incorporation of essential oils into biodegradable poly(ε-caprolactone) nanoparticles increased their efficiency as biofungicides in the fight against coffee rust, decreasing the severity of the disease by up to 90·75% after treatment with the nanoparticles containing the essential oil from E. grandis.

BACKGROUND: Acute blood pressure (BP) management in neurologic patients is paramount. Different neurologic emergencies dictate various BP goals. There remains a lack of literature determining the optimal BP regimen regarding safety and efficacy. The objective of this study was to identify which intravenous antihypertensive is the most effective and safest for acute BP management in neurologic emergencies. METHODS: Ovid EBM (Evidence Based Medicine) Reviews, Ovid Embase, Ovid Medline, Scopus, and Web of Science Core Collection were searched from inception to August 2020. Randomized controlled trials or comparative observational studies that evaluated clevidipine, nicardipine, labetalol, esmolol, or nitroprusside for acute neurologic emergencies were included. Outcomes of interest included mortality, functional outcome, BP variability, time to goal BP, time within goal BP, incidence of hypotension, and need for rescue antihypertensives. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to evaluate the degree of certainty in the evidence available. RESULTS: A total of 3878 titles and abstracts were screened, and 183 articles were selected for full-text review. Ten studies met the inclusion criteria; however, the significant heterogeneity and very low quality of studies precluded a meta-analysis. All studies included nicardipine. Five studies compared nicardipine with labetalol, three studies compared nicardipine with clevidipine, and two studies compared nicardipine with nitroprusside. Compared with labetalol, nicardipine appears to reach goal BP faster, have less BP variability, and need less rescue antihypertensives. Compared with clevidipine, nicardipine appears to reach goal BP goal slower. Lastly, nicardipine appears to be similar for BP-related outcomes when compared with nitroprusside; however, nitroprusside may be associated with increased mortality. The confidence in the evidence available for all the outcomes was deemed very low. CONCLUSIONS: Because of the very low quality of evidence, an optimal BP agent for the treatment of patients with neurologic emergencies was unable to be determined. Future randomized controlled trials are needed to compare the most promising agents.

We conducted a systematic review and meta-analysis to identify risk factors for delirium in geriatric patients in the emergency department and to identify emergency department (ED)-based modifiable risk factors for developing delirium during hospitalization. We searched evidence based medicine reviews, EMBASE, MEDLINE, Scopus, and Web of Science for observational studies from the time of their inception to July 2020. We included studies that evaluated potential risk factors for either prevalent or incident delirium among older adults (age ≥ 60 years) presenting to the ED. When appropriate, we meta-analyzed estimates for risk factors using a random-effects model. The certainty of evidence was evaluated using the grading of recommendations assessment, development and evaluation approach. The study's protocol was registered in PROSPERO (CDR42020175261). A total of 4,513 citations were reviewed, and 34 studies met the criteria for inclusion: 27 evaluating risk factors for ED delirium (13,412 patients) and 7 evaluating ED-based risk factors for developing delirium during hospitalization (2,238 patients). The prevalence of ED delirium ranged from 7% to 35%. Four factors had strong associations with ED delirium and were graded as high-certainty evidence, including nursing home residence (4 studies; odds ratio [OR], 3.45; 95% confidence interval [CI], 2.17 to 5.48), cognitive impairment (7 studies; OR, 4.46; 95% CI, 3.38 to 5.89), hearing impairment (3 studies, OR, 2.57; 95% CI, 1.03 to 6.41), and a history of stroke (3 studies; OR, 3.20; 95% CI, 1.17 to 8.75). The rate of developing delirium during hospitalization ranged from 11% to 27%. A length of stay of more than 10 hours in ED was associated with a higher risk of delirium (1 study; OR, 2.23; 95% CI, 1.13 to 4.41). One study reported that severe pain, rather than the use of opioids, was associated with the development of delirium. These findings can be used to prioritize delirium screening in the ED and develop novel ED delirium risk scores or prevention interventions.

OBJECTIVE: To compare resource utilization and mortality between older and younger adult patients with similar ED chief complaints and ESI triage levels. METHODS: This was an observational study of consecutive adult patients (age ≥ 40) who presented to an academic ED over a 1-year period with chest pain, abdominal pain, altered mental status, generalized weakness, or headache. Patients were categorized into 40-64, 65-79, and ≥ 80-year old groups. Mortality and utilization outcomes were compared between age groups through logistic regression models or Cox proportional hazards adjusting for ESI level and chief complaint. Odds ratios (OR) and hazard ratios (HR) were calculated with 95% confidence intervals (CI). RESULTS: A total of 9798 ED visits were included. As compared to younger adults (age 40-64), older adults, independently of ESI level and chief complaint, had higher ED laboratory use (OR 1.46 [CI 1.29, 1.66] for age 65-80; OR 1.33 [CI 1.15, 1.55] for age ≥ 80), ED radiology use (OR 1.40 [CI 1.26, 1.56]; OR 1.48 [CI 1.30, 1.69]), hospital admission (OR 1.56 [CI 1.42, 1.72]; OR 1.97 [CI 1.75, 2.21]), and ICU admission (OR 1.38 [CI 1.15, 1.65]; OR 1.23 [CI 0.99, 1.52]). Despite similar ESI and chief complaint, patients age 65-79 and ≥ 80 had higher 30-day mortality rates (HR 1.87 [CI 1.39 to 2.51] and 2.47 [CI 1.81 to 3.37], respectively). CONCLUSIONS: Older adults with similar chief complaints and ESI levels than younger adults, have significantly higher ED resource use, hospitalization rates, and mortality.

OBJECTIVE: To identify predictors of 30-day emergency department (ED) return visits in patients age 65-79 years and age ≥ 80 years. METHODS: This was a cohort study of older adults who presented to the ED over a 1-year period. A mixed-effects logistic regression model was used to identify predictors for returning to the ED within 30 days. We stratified the cohort into those aged 65-79 years and aged ≥80 years. Adjusted odds ratios (aORs) with 95% confidence intervals (CI) were reported. This study adhered to the STROBE reporting guidelines. RESULTS: A total of 21,460 ED visits representing 14,528 unique patients were included. The overall return rate was 15% (1998/13,300 visits) for age 65-79 years, and 16% (1306/8160 visits) for age ≥ 80 years. A history of congestive heart failure (CHF), dementia, or prior hospitalization within 2 years were associated with increased odds of returning in both age groups (for age 65-79: CHF aOR 1.36 [CI 1.16-1.59], dementia aOR 1.27 [CI 1.07-1.49], prior hospitalization aOR 1.36 [CI 1.19-1.56]; for age ≥ 80: CHF aOR 1.32 [CI 1.13-1.55], dementia aOR 1.22 [CI 1.04-1.42], and prior hospitalization aOR 1.27 [CI 1.09-1.47]). Being admitted from the ED was associated with decreased odds of returning to the ED within 30 days (aOR 0.72 [CI 0.64-0.80] for age 65-79 years and 0.72 [CI 0.63-0.82] for age ≥ 80). CONCLUSION: Age alone was not an independent predictor of return visits. Prior hospitalization, dementia and CHF were predictors of 30-day ED return. The identification of predictors of return visits may help to optimize care transition in the ED.

OBJECTIVE: To evaluate the prognostic accuracy of qSOFA for predicting in-hospital mortality among patients with suspected infection presenting to the ED of a public tertiary hospital in Brazil. METHODS: We performed a retrospective cohort study of consecutive adult patients (age ≥ 18 years) with suspected infection who presented to an academic tertiary ED in Porto Alegre (Southern Brazil) during an 18-month period. The qSOFA was calculated by using information collected at triage and patients were followed throughout hospitalization for the primary outcome of in-hospital mortality. Sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratios with corresponding 95% CIs were calculated for the qSOFA and qSOFA65. RESULTS: A total of 7523 ED visits of patients with suspected infection in which an intravenous antibiotic was administered within 24 h were included, which resulted in 908 in-hospital deaths (12.1%). There were 690 (9.2%) patients whose triage qSOFA was ≥2 points. When such cutoff was used, the sensitivity for in-hospital death was 24.6% (95% CI 21.8 to 27.4%) and the specificity was 92.9% (95% CI 92.3% to 93.5%). The sensitivity increased to 67.4% (95% CI 64.2% to 70.3%) when a cutoff of ≥1 was tested, but the specificity decreased to 55.3% (95% CI 54.1% to 56.5%). Using a cutoff of ≥2, the qSOFA65 had a sensitivity of 51.0% (95% CI 47.7% to 54.3%) and a specificity of 75.7% (95% CI 74.6% to 76.7%). CONCLUSIONS: The qSOFA score yielded very low sensitivity in predicting in-hospital mortality. Emergency physicians or ED triage nurses in low-to-middle income countries should not be using qSOFA or qSOFA65 as "rule-out" screening tools in the initial evaluation of patients with suspected infection.

BACKGROUND: The development of an author-level complementary metric could play a role in the process of academic promotion through objective evaluation of scholars' influence and impact. OBJECTIVE: The objective of this study was to evaluate the correlation between the Healthcare Social Graph (HSG) score, a novel social media influence and impact metric, and the h-index, a traditional author-level metric. METHODS: This was a cross-sectional study of health care stakeholders with a social media presence randomly sampled from the Symplur database in May 2020. We performed stratified random sampling to obtain a representative sample with all strata of HSG scores. We manually queried the h-index in two reference-based databases (Scopus and Google Scholar). Continuous features (HSG score and h-index) from the included profiles were summarized as the median and IQR. We calculated the Spearman correlation coefficients (ρ) to evaluate the correlation between the HSG scores and h-indexes obtained from Google Scholar and Scopus. RESULTS: A total of 286 (31.2%) of the 917 stakeholders had a Google Scholar h-index available. The median HSG score for these profiles was 61.1 (IQR 48.2), and the median h-index was 14.5 (IQR 26.0). For the 286 subjects with the HSG score and Google Scholar h-index available, the Spearman correlation coefficient ρ was 0.1979 (P<.001), indicating a weak positive correlation between these two metrics. A total of 715 (78%) of 917 stakeholders had a Scopus h-index available. The median HSG score for these profiles was 57.6 (IQR 46.4), and the median h-index was 7 (IQR 16). For the 715 subjects with the HSG score and Scopus h-index available, ρ was 0.2173 (P<.001), also indicating a weak positive correlation. CONCLUSIONS: We found a weak positive correlation between a novel author-level complementary metric and the h-index. More than a chiasm between traditional citation metrics and novel social media-based metrics, our findings point toward a bridge between the two domains.

STUDY OBJECTIVE: To assess the efficacy and safety of intranasal analgesic-dose ketamine as compared to intranasal fentanyl for pediatric acute pain. METHODS: A systematic review and meta-analysis was performed following the PRISMA guidelines. We searched PubMed, Embase, and Scopus databases for randomized controlled trials from inception to December 2019. We conducted meta-analysis with random-effects models to evaluate pain reduction, rescue analgesia, adverse events and sedation between intranasal ketamine and intranasal fentanyl. Random-effects models were used to estimate weighted mean differences (WMD) and pooled relative risks (RR). RESULTS: A total of 546 studies were screened and 4 trials were included. In the meta-analysis of 4 studies including 276 patients, ketamine had similar reductions in pain scores from baseline to all post-intervention times (10 to 15â¯min: WMD -1.42, 95% CI -9.95 to 7.10; 30â¯min: WMD 0.40, 95% CI -6.29 to 7.10; 60â¯min: WMD -0.64, 95% CI -6.76 to 5.47). Ketamine was associated with similar rates of rescue analgesia (RR 0.74, 95% CI 0.44 to 1.25). Ketamine had a higher risk of non-serious adverse events (RR 2.00, 95% CI 1.43 to 2.79), and no patients receiving ketamine had a serious adverse event. There was one serious adverse event (hypotension) with fentanyl that self-resolved. No patients receiving either IN fentanyl or ketamine had significant sedation. CONCLUSION: Intranasal analgesic-dose ketamine may be considered as an alternative to opioids for acute pain management in children. Its accepted use will depend on the tolerability of non-serious adverse events and the desire to avoid opioids.

STUDY OBJECTIVE: To summarize interventions that impact the experience of older adults in the emergency department (ED) as measured by patient experience instruments. METHODS: This is a systematic review to evaluate interventions aimed to improve geriatric patient experience in the ED. We searched Ovid CENTRAL, Ovid EMBASE, Ovid MEDLINE and PsycINFO from inception to January 2019. The main outcome was patient experience measured through instruments to assess patient experience or satisfaction. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the confidence in the evidence available. RESULTS: The search strategy identified 992 studies through comprehensive literature search and hand-search of reference lists. A total of 21 studies and 3163 older adults receiving an intervention strategy aimed at improve patient experience in the ED were included. Department-wide interventions, including geriatric ED and comprehensive geriatric assessment unit, focused care coordination with discharge planning and referral for community services, were associated with improved patient experience. Providing an assistive listening device to those with hearing loss and having a pharmacist reviewing the medication list showed an improved patient perception of quality of care provided. The confidence in the evidence available for the outcome of patient experience was deemed to be very low. CONCLUSION: While all studies reported an outcome of patient experience, there was significant heterogeneity in the tools used to measure it. The very low certainty in the evidence available highlights the need for more reliable tools to measure patient experience and studies designed to measure the effect of the interventions.

OBJECTIVE: To characterize pediatric Emergency Medicine Service (EMS) transports to the Emergency Department (ED) using a national claims database. METHODS: We included children, 18â¯years and younger, transported by EMS to an ED, from 2007 to 2016 in the OptumLabs Data Warehouse. ICD-9 and ICD-10 diagnosis codes were used to categorize disease system involvement. Interventions performed were extracted using procedure codes. ED visit severity was measured by the Minnesota Algorithm. RESULTS: Over a 10-year period, 239,243 children were transported. Trauma was the most frequent diagnosis category for transport for children ≥5â¯years of age, 35.1% (age 6-13) and 32.7% (age 14-18). The most common diagnosis category in children <6â¯years of age was neurologic (29.3%), followed by respiratory (23.1%). Over 10â¯years, transports for mental disorders represented 15.3% in children age 14 to 18, and had the greatest absolute increase (rate differenceâ¯+â¯10.4 per 10,000) across all diagnoses categories. Neurologic transports also significantly increased in children age 14 to 18 (rate differenceâ¯+â¯6.9 per 10,000). Trauma rates decreased across all age groups and had its greatest reduction among children age 14 to 18 (rate differenceâ¯-â¯6.8 per 10,000). Across all age groups, an intervention was performed in 15.6%. Most children (83.3%) were deemed to have ED care needed type of visit, and 15.8% of the transports resulted in a hospital admission. CONCLUSION: Trauma is the most frequent diagnosis for transport in children older than 5â¯years of age. Mental health and neurologic transports have markedly increased, while trauma transports have decreased. Most children arriving by ambulance were classified as requiring ED level of care. These changes might have significant implication for EMS personnel and policy makers.

A strain of embryonic human kidney cells (HEK293) was transiently co-transfected with the expression vectors coding for the α- and ß-subunits of human thyroid-stimulating hormone (hTSH), and, for the first time, a human cell-derived recombinant hTSH was synthesized and extensively characterized. The purification strategy involving two steps provided an overall yield of 55% and a purity level > 90%. The purified material (hTSH-HEK) was analyzed and compared to a CHO-derived recombinant preparation (hTSH-CHO) and to a pituitary-derived (hTSH-Pit) preparation. The three preparations showed an equivalent purity (> 95%) with a hTSH-HEK molecular mass 2.1% lower than that of hTSH-CHO and 2.7% higher than that of hTSH-Pit. Remarkable differences were found in the carbohydrate moiety, the lowest sialic acid content and highest fucose content being observed in hTSH-HEK. In vivo biological activity was confirmed for the three preparations, the hTSH-HEK bioactivity being 39 and 16% lower than those of hTSH-CHO and hTSH-Pit, respectively. The hTSH-HEK circulatory half-life (t 1/2) was also shorter than those of hTSH-CHO (1.5-fold) and hTSH-Pit (1.2-fold). According to these findings, HEK-293-derived hTSH can be considered to be useful for clinical applications, in view as well of its human origin and particular carbohydrate composition.
