Patient Perspectives on Digital Interventions to Manage Heart Failure Medications: The VITAL-HF Pilot.

Use of guideline-directed medical therapy (GDMT) for treatment of heart failure with reduced ejection fraction (HFrEF) remains unacceptably low. The purpose of this study was to determine whether a digital health tool can augment GDMT for patients with HFrEF. Participants ≥ 18 years old with symptomatic HFrEF (left ventricular ejection fraction ≤ 40%) and with access to a mobile phone with internet were included. Participants were given a blood pressure cuff, instructed in its use, and given regular symptom surveys via cell-phone web-link. Data were transmitted to the Story Health web-based platform, and automated alerts were triggered based on pre-specified vital sign and laboratory data. Health coaches assisted patients with medication education, pharmacy access, and lab access through text messages and phone calls. GDMT titration plans were individually created in the digital platform by local clinicians based on entry vitals and labs. Twelve participants enrolled and completed the study. The median age and LVEF were 52.5 years (IQR, 46.5-63.5) and 25% (IQR, 22.5-35.5), respectively. There were 10 GDMT initiations, 52 up-titrations, and 13 down-titrations. Five participants engaged in focus-group interviews following study completion to understand first-hand perspectives regarding the use of digital tools to manage GDMT. Participants expressed comfort knowing that there were clinicians regularly reviewing their data. This alleviated concerns of uncertainty in daily living, led to an increased feeling of security, and empowered patients to understand decision-making regarding GDMT. Frequent medication changes, and the associated financial impact, were common concerns. Remote titration of GDMT for HFrEF is feasible and appears to be a patient-centered approach to care.

What to know about 2.0: Revisions to the pediatric emergency medicine milestones.

Introduction: The Accreditation Council for Graduate Medical Education (ACGME) adopted educational milestones for trainee assessment in 2013, as a key component of the Next Accreditation System. Two years later, the ACGME, American Board of Pediatrics (ABP), and American Board of Emergency Medicine (ABEM) collaborated to create specialty-specific subcompetencies in pediatric emergency medicine (PEM). Since that time, emerging data have demonstrated the need to revise specialty milestones. Consequently, the ACGME summoned a working group to revise the original PEM milestones. Methods: The PEM Milestones 2.0 Working Group convened in April 2021, comprising diverse representation from ACGME staff, PEM and EM attendings, PEM fellowship program directors, PEM fellows, and community members, overseen by the ACGME's vice president for milestones development. The group met virtually six times over 3 months, with concurrent independent and subgroup work, to draft the PEM Milestones 2.0 and supplemental guide. Results: The working group's revisions generated concise descriptions of behavioral anchors to define skill acquisition more accurately; attention to the transition from residency to fellowship training; incorporation of harmonized milestones for non-patient care and non-medical knowledge domains; and increased emphasis on diversity, equity, and inclusion. A supplemental guide was also designed to aid programs in designing programmatic assessment related to specialty-specific milestones. Conclusions: The PEM Milestones 2.0 provide an updated, specialty-specific framework to guide the development and assessment of PEM fellows and training programs. Future work may focus on faculty and learner development, advancing validity evidence, strengthening content expertise, and integrating milestones with specialty-specific entrustable professional activities.

Inappropriate Shock Delivery Is Common During Pediatric In-Hospital Cardiac Arrest.

OBJECTIVES: To characterize inappropriate shock delivery during pediatric in-hospital cardiac arrest (IHCA). DESIGN: Retrospective cohort study. SETTING: An international pediatric cardiac arrest quality improvement collaborative Pediatric Resuscitation Quality [pediRES-Q]. PATIENTS: All IHCA events from 2015 to 2020 from the pediRES-Q Collaborative for which shock and electrocardiogram waveform data were available. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We analyzed 418 shocks delivered during 159 cardiac arrest events, with 381 shocks during 158 events at 28 sites remaining after excluding undecipherable rhythms. We classified shocks as: 1) appropriate (ventricular fibrillation [VF] or wide complex ≥ 150/min); 2) indeterminate (narrow complex ≥ 150/min or wide complex 100-149/min); or 3) inappropriate (asystole, sinus, narrow complex < 150/min, or wide complex < 100/min) based on the rhythm immediately preceding shock delivery. Of delivered shocks, 57% were delivered appropriately for VF or wide complex rhythms with a rate greater than or equal to 150/min. Thirteen percent were classified as indeterminate. Thirty percent were delivered inappropriately for asystole (6.8%), sinus (3.1%), narrow complex less than 150/min (11%), or wide complex less than 100/min (8.9%) rhythms. Eighty-eight percent of all shocks were delivered in ICUs or emergency departments, and 30% of those were delivered inappropriately. CONCLUSIONS: The rate of inappropriate shock delivery for pediatric IHCA in this international cohort is at least 30%, with 23% delivered to an organized electrical rhythm, identifying opportunity for improvement in rhythm identification training.

Quantitative Blood Volume Analysis and Hemodynamic Measures of Vascular Compliance in Patients With Worsening Heart Failure.

BACKGROUND: The role of blood volume (BV) expansion vs a change in vascular compliance in worsening heart failure (HF) remains under debate. We aimed to assess the relationship between BV and resting and stress hemodynamics in worsening HF and to further elucidate the significance of BV in cardiac decompensation. METHODS AND RESULTS: Patients with worsening HF underwent radiolabeled indicator-dilution BV analysis and cardiac catheterization. Intravascular volumes and resting/stress hemodynamics were recorded. Provocative stress maneuvers included change in systolic blood pressure (ΔSBP) from lying to standing and Valsalva and intracardiac pressure changes with leg raise. Correlation between BV and invasive hemodynamics were assessed by linear regression. Of 27 patients with worsening HF, patients' characteristics included mean age 61 ± 12 years, 70% male, 19% Black, and mean ejection fraction 29% ± 15%. Of the patients, 13 (48%) had hypervolemia as measured by total BV, which weakly correlated with ΔSBP by position (R2 = 0.009) and Valsalva (R2 = 0.003) and with right atrial (R2 = 0.049) and pulmonary capillary wedge (R2 = 0.047) pressure changes during leg raise. CONCLUSIONS: In patients with worsening HF, BV mildly correlated with intracardiac pressures at rest. Provocative maneuvers intended to test vascular compliance did not correlate with BV, indicating that compliance may serve as a stand-alone metric in HF.

Going viral: A scoping review of the current state and impact of online research dissemination in emergency medicine.

BACKGROUND: The use of free open-access medical education (FOAM) and other online knowledge dissemination methods has increased over the past decade. However, the role and impact of these tools in the knowledge translation continuum are poorly understood, potentially limiting the ability of knowledge generators to fully harness and exploit their potential. Here, we aim to comprehensively map and synthesize the literature describing the use of online tools for the dissemination of emergency medicine research. METHODS: Using scoping review methodology, we searched the traditional literature via PubMed, CINAHL, EMBASE, ERIC, SCOPUS, and the gray literature for publications exploring online methods to disseminate new research findings. We synthesized the results and constructed a conceptual model of current research dissemination methods. RESULTS: We included 79 out of 655 unique abstracts and articles identified in our search, 62 of which were from the traditional literature. We describe six primary domains: integration with traditional literature, measurement of dissemination, online organizations and communities of practice, professional development, quality assurance tools and techniques, and advantages and disadvantages of FOAM. For each domain we present an exemplar article and prevailing gaps in knowledge. Finally, we propose a current conceptual framework for dissemination of new research findings that describes both traditional and novel methods of dissemination. CONCLUSIONS: This comprehensive review of the literature and current dissemination framework will empower researchers, research networks, and granting organizations to maximize their use of FOAM and other online methods to disseminate new knowledge as well as provide clinicians a better understanding of the tools and methods by which to access and implement new research findings.

Risk of malignancy following emergency department Bell's palsy diagnosis in children.

OBJECTIVE: To quantify the risk of malignancy following the emergency department (ED) diagnosis of Bell's Palsy (BP) using a large retrospective cohort. STUDY DESIGN: We performed a cohort study using the Pediatric Health Information System database. We included all children (6 months - 17 years) from 2011 to 2020 with an ED diagnosis of BP. We excluded children with previous neurologic chronic condition or malignancy diagnosed during or prior to the index visit. Our primary outcome was diagnosis of malignancy within 60 days following the index ED visit. We compared clinical characteristics between children with and without new-onset malignancy. RESULTS: Of 12,272 encounters for BP, 41 had a new oncologic diagnosis within 60 days (0.33%, 95% confidence interval [CI]: 0.25-0.45%). Median time to oncologic diagnosis was 22 days. Primary CNS malignancy (59%) and leukemia (17.1%) were the most common diagnoses. Younger children had a higher incidence of new oncologic diagnosis compared with older children. Incidences were 0.68% (95% CI 0.36-1.3%), 0.70% (95% CI 0.38-1.3%), 0.26% (95% CI 0.15-0.47%), and 0.21% (95% CI 0.12-0.37%) for children aged <2 years, 2-5 years, 6-11 years, and 12-17 years respectively. CONCLUSIONS: We found a small but potentially clinically significant rate of new-onset oncologic diagnosis within 60 days after BP diagnosis in the ED, especially in children younger than 5 years. Further studies of the diagnostic utility of laboratory testing or neuroimaging and the risk of empiric steroids in children with BP are needed.

Timely Monitoring of Inflammation by Fecal Lactoferrin Rapidly Predicts Therapeutic Response in Inflammatory Bowel Disease.

BACKGROUND: Fecal lactoferrin (FL) levels may mirror drug-induced changes in inflammation in ulcerative colitis and Crohn disease in a timely way and could be used to assess loss of response (LOR) to biologics. METHODS: This study is a retrospective outcome review in 61 patients on adalimumab, infliximab, or vedolizumab managed in our center and followed for 6 to 24 months. Patients were 1) in clinical remission or 2) were experiencing possible LOR. RESULTS: For group 1, in 71% of 31 patients, FL slowly increased during the therapeutic interval (R2 = 0.769; P < 0.001), thus reflecting increasing inflammation as drug concentrations decreased. In the remaining patients, FL was undetectable throughout the therapeutic interval because of a stronger suppression of inflammation. For group 2, in 30 patients negative for infections, FL levels measured 1 to 3 days after infusion/injection compared to preadministration values either increased (nonresponders)-in these patients the medication was switched to another class; partially decreased (partial responders)-the therapeutic interval was shortened; or were normal throughout (responders)-causes for symptoms unrelated to disease activity were found for all. After FL-based management, 3-month standardized clinical scores were normalized in both partial responders (0.58 ±â€…0.21 vs 0.13 ±â€…0.09; P < 0.001) and nonresponders (0.81 ±â€…0.17 vs 0.12 ±â€…0.08; P < 0.001), and FL levels dropped by up to 99%. CONCLUSIONS: Levels of FL reflect drug-induced changes in mucosal inflammation in a timely way, thus enabling rapid assessment of therapeutic response in patients with ulcerative colitis and with Crohn disease. In patients with suspected LOR, FL levels before and after infusion/injection accurately separated responders, partial responders, and nonresponders. The strategy proposed here is simple, accurate, and easily applicable to clinical practice.

Case Studies of Challenges in Emergency Care for Children With Autism Spectrum Disorder.

ABSTRACT: Autism spectrum disorder (ASD) affects more than 1% of children in the United States, with the rate of new diagnoses climbing significantly in the last 15 years. Emergent conditions and subsequent visits to the emergency department (ED) can be particularly challenging for children with ASD, most of whom also have comorbidities in addition to their deficits in social communication and interaction. In the emergency setting, these conditions can cause a range of behaviors that result in challenges for health care providers and may result in suboptimal experiences for children with ASD and their families. We present the ED course of 3 children with ASD to illustrate these challenges, emphasize successful strategies, and highlight opportunities for improvement.

Fecal Lactoferrin and Other Stool Markers during Normal Pregnancy and in Inflammatory Bowel Diseases: A Prospective Study and Review of the Literature.

INTRODUCTION: Management of inflammatory bowel diseases (IBDs) - both Crohn's disease (CD) and ulcerative colitis (UC) - during pregnancy can be challenging since most monitoring tools available in nonpregnant patients are contraindicated. OBJECTIVES: The aim of the study was to test whether fecal inflammatory markers - specifically fecal lactoferrin - physiologically change during normal pregnancy as a prerequisite to use them to monitor IBD activity during pregnancy. METHODS: Fecal lactoferrin was tested in healthy pregnant and nonpregnant women from the same geographic area and age range (18-40 years) - all negative for clinical gastrointestinal tract inflammation. A retrospective review of fecal lactoferrin levels contrasted with the Simple Endoscopic Score for CD, and the Disease Activity Index for UC was also performed in women with active IBDs within the same age range and geographical area. RESULTS: In 30 nonpregnant subjects, fecal lactoferrin levels were 0.87 ± 1.08 µg/g. In 49 pregnant subjects, levels were 0.59 ± 0.83, 0.87 ± 1.13, and 0.85 ± 1.06 µg/g during the first, second, and third trimester, respectively (p = 0.64), with average levels for the 3 trimesters of 0.81 ± 1.04 µg/g (p = 0.61 compared to nonpregnant subjects). Sequential fecal lactoferrin levels (n = 26) did not differ from one trimester to the other in the individual subjects (p = 0.80). In 45 female IBD patients (27 with CD and 18 with UC), fecal lactoferrin levels were correlated with disease activity as defined by the endoscopic scores: 218, 688, and 1,175 µg/g for CD and 931, 2,088, and 2,509 µg/g for UC, respectively, for mild, moderate, and severe activity. CONCLUSIONS: Fecal lactoferrin levels during normal pregnancy are superimposable to those of nonpregnant women and significantly below levels in women of the same childbearing age with active IBDs. Additional published data - reviewed in this atricle - and our own indicate that fecal lactoferrin and other markers can be potentially used to monitor disease activity in pregnant IBD patients.

Low glutamate dehydrogenase levels are associated with colonization in Clostridium difficile PCR-only positive patients with inflammatory bowel disease.

BACKGROUND/AIMS: Clostridioides difficile infection (CDI) remains a diagnostic challenge in patients with inflammatory bowel disease (IBD). We tested novel biomarkers to differentiate CDI from colonization in patients without (CDI-only) and with IBD (IBD-CDI). METHODS: Samples were enzyme immunoassay (EIA)-tested for glutamate dehydrogenase (GDH) and toxin, followed by reflex PCR. Quantitative GDH [(qGDH) - a novel indicator of Clostridium difficile load] and stool lactoferrin were tested at days 0, 3 and 10 during antibiotic treatment. Samples were also analyzed for toxin B cytotoxicity neutralization assay (CNA) and toxigenic culture, gold standards to detect free toxin and virulent bacteria, respectively. RESULTS: Forty-five symptomatic patients (28 CDI-only, 13 with Crohn's disease, 4 with ulcerative colitis) were recruited with 3 sequential samples available for 36 (21 CDI-only, 15 IBD-CDI). Thirty-nine of 45 (87%) cases were toxigenic culture-positive. In the CDI-only group, 78.6% were positive for EIA-toxin, 21.4% were PCR-positive while 82.1% were CNA-positive. In the IBD-CDI group, only one patient (6%) was EIA-toxin positive and 17.6% CNA-positive. The median qGDH level at day 0 was higher in CNA-positive patients compared to CNA-negative patients (1111 vs. 146 ng/g, P = 0.004) and dropped together with lactoferrin from day 0 to 10. CDI eradication improved symptoms in 72.2% of patients with CDI-only. In 60% of patients with IBD-CDI, eradication was ineffective, with symptoms improving in 89% of them after IBD therapy intensification. CONCLUSION: In patients with IBD-CDI, PCR-only positivity might mainly reflect colonization rather than disease. C. difficile load by qGDH correlates with CNA-detected toxin and together with stool lactoferrin might differentiate CDI from colonization in patients with IBD.

Ondansetron Prescription for Home Use in a Pediatric Emergency Department.

OBJECTIVES: Ondansetron has been shown to decrease admission rate and the need for intravenous fluids among pediatric emergency department (ED) patients with acute gastroenteritis, but there is limited evidence regarding its use after ED discharge. This study describes prescribing patterns for ondansetron and assesses the effects of ondansetron home prescription on rate of return. METHODS: Data were gathered from the electronic health record on 2 separate but overlapping groups of patients seen in a pediatric ED from 2012 to 2014. The Gastroenteritis Group included all patients with a discharge diagnosis of gastroenteritis by International Classification of Diseases, Ninth Revision, code. The All Ondansetron Group included any child prescribed ondansetron at discharge. Patterns of ondansetron use and 3- and 7-day ED return rate were assessed for both groups. Discharge diagnosis was evaluated for the All Ondansetron Group. RESULTS: A total of 996 patients with acute gastroenteritis were identified during the study period. Of these, 76% received ondansetron in the ED, and 71% were discharged with prescriptions for ondansetron. Seven-day ED return rates were similar between groups (6% with prescription, 5% without, P = 0.66). A total of 2287 patients received home prescriptions for ondansetron. Fifty-four percent of these patients' discharge diagnoses were classed as gastrointestinal complaints, 14% other infectious conditions, 9% respiratory, and 4% injuries. Their return rate was 6%. There was wide variation in the number of doses prescribed. CONCLUSIONS: Home-use ondansetron is widely prescribed in this urban academic pediatric ED for a variety of indications, without effect on 3- or 7-day ED return. Further prospective studies are necessary to determine the efficacy of this practice.

Procedural sedation in children with autism spectrum disorders in the emergency department.

BACKGROUND AND OBJECTIVES: Children with autism spectrum disorder (ASD) present more frequently to the emergency department (ED) than children with normal development, and frequently have injuries requiring procedural sedation. Our objective was to describe sedation practice and outcomes in children with ASD in the ED. METHODS: We performed a retrospective chart review of children with ASD who underwent sedation at two tertiary care EDs between January 2009-December 2016. Data were collected on children 1-18 years of age with ASD who were sedated in the ED. RESULTS: There were 6020 ED visits by children with ASD, 126 (2.1%) of whom received sedation. The most frequent indications for sedation were laceration repair (24.6%), incision and drainage (17.5%), diagnostic imaging (14.3%), and physical examination (11.9%). The most common sedatives used were ketamine (50.8%) and midazolam (50.8%). Ketamine was most commonly given intravenously (71.9%), while midazolam was usually given intranasally (71.9%). Procedures could not be completed in 4 (3.2%) patients, and adverse events were noted in 23 (18.3%) patients. Only four (3.2%) patients required supplemental oxygenation, and one received positive pressure ventilation. CONCLUSIONS: Children with autism in the ED commonly received sedation; one in four of which were for non-painful diagnostic procedures or physical examination. Over one-third received sedation via a non-parenteral route for intended minimal sedation. Sedative medication dosing and observed adverse events were similar to those reported previously in children without ASD. Emergency providers must be prepared to meet the unique sedation needs of children with ASD.

Fecal lactoferrin accurately reflects mucosal inflammation in inflammatory bowel disease.

BACKGROUND: Studies have demonstrated a potential role for fecal biomarkers such as fecal calprotectin (FC) and fecal lactoferrin (FL) in monitoring inflammatory bowel diseases (IBD) - Crohn's disease (CD) and ulcerative colitis (UC). However, their correlation to endoscopic scores, disease severity and affected intestinal surface has not been extensively investigated. AIM: To correlate FL, and for comparison white blood cell (WBC) and C-reactive protein (CRP), with endoscopic scores, disease extent and location in CD and UC. METHODS: Retrospective analysis in 188 patients who had FL, CRP and WBC determined within 30 d of endoscopy. Disease location, disease extent (number of intestinal segments involved), disease severity (determined by endoscopic scores), timing of FL testing in relation to colonoscopy, as well as the use of effective fast acting medications (steroids and biologics) between colonoscopy and FL measurement, were recorded. RESULTS: In 131 CD and 57 UC patients, both CRP and FL - but not WBC - distinguished disease severity (inactive, mild, moderate, severe). In patients receiving fast-acting (steroids or biologics) treatment in between FL and colonoscopy, FL showed a higher correlation to endoscopic scores when tested before vs after the procedure (r = 0.596, P < 0.001, vs r = 0.285, P = 0.15 for the Simple Endoscopic Score for CD; and r = 0.402, P = 0.01 vs r = 0.054 P = 0.84 for Disease Activity Index). Finally, FL was significantly correlated with the diseased mucosal surface (colon-ileocolon > small bowel) and the number of inflamed colon segments. CONCLUSION: FL and CRP separated disease severity categories with FL showing lower discriminating P-values. FL showed a close correlation with the involved mucosal surface and with disease extent and was more closely correlated to endoscopy when determined before the procedure - this indicating that inflammatory activity changes associated with therapy might be rapidly reflected by FL levels. FL can accurately and timely characterize intestinal inflammation in IBD.

Tacrolimus-associated hemolytic uremic syndrome in a pediatric heart transplant recipient.

HUS is a well-known entity primarily associated with bacterial infection and is characterized by a classic triad of anemia, thrombocytopenia, and kidney injury. Its atypical form has been associated with calcineurin inhibitors and has been extensively discussed in renal transplantation. We present a case of tacrolimus-associated HUS in a pediatric heart transplant recipient, which we believe to be previously unreported in the literature.

Omphalith-associated relapsing umbilical cellulitis: recurrent omphalitis secondary to a hair-containing belly button bezoar.

We report an 18-year-old man with recurrent cellulitis of his umbilicus and surrounding skin. Thorough investigation revealed a foreign body as the source of his relapsing infection, a compact collection of terminal hair shafts. Spontaneously occurring stonelike foreign bodies resulting from the accumulation and concretion of keratinous and amorphous sebaceous material within the umbilicus are referred to as omphaliths. However, because the composition of our patient's foreign body is pilar in origin, we propose that the foreign body be designated as either an omphalotrich or trichomphalith. Alternatively, because the umbilicus and epithelium of the gastrointestinal tract are embryologically related, we suggest that our patient's hair-containing foreign body be referred to as a trichobezoar, which is used to describe exogenous foreign bodies composed of ingested hair in the gastrointestinal tract. The patient's cellulitis resolved without any subsequent episodes following the removal of his belly button bezoar.
