Association of emergency department characteristics with presence of recommended pediatric-specific behavioral health policies.

Objectives: In the United States, pediatric emergency department (ED) visits for behavioral health (BH) are increasing. We sought to determine ED-level characteristics associated with having recommended BH-related policies. Methods: We conducted a retrospective serial cross-sectional study of National Pediatric Readiness Project assessments administered to US EDs in 2013 and 2021. Changes in responses related to BH items over time were examined. Multivariable logistic regression models examined ED characteristics associated with the presence of specific BH-related policies in 2021. Results: Of 3554 EDs that completed assessments in 2021, 73.0% had BH-related policies, 66.5% had transfer guidelines for children with BH issues, and 38.6% had access to BH resources in a disaster. Of 2570 EDs that completed assessments in both 2013 and 2021, presence of specific BH-related policies increased from 48.6% to 72.0% and presence of appropriate transfer guidelines increased from 56.2% to 64.9%. The adjusted odd ratios (aORs) of having specific BH-related policies were lower in rural (aOR 0.73; 95% confidence interval [CI] 0.57, 0.92) and remote EDs (aOR 0.65; 95% CI 0.48, 0.88) compared to urban EDs; lower among EDs with versus without trauma center designation (aOR 0.80; 95% CI 0.67, 0.95); and higher among EDs with a nurse and physician pediatric emergency care coordinator (PECC) (aOR 1.89; 95% CI 1.54, 2.33) versus those without a PECC. Conclusion: Although pediatric readiness for BH conditions increased from 2013 to 2021, gaps remain, particularly among rural EDs and designated trauma centers. Having nurse and physician PECCs is a modifiable strategy to increase ED pediatric readiness pertaining to BH.

Strategies for optimal management of pediatric acute agitation in emergency settings.

Acute agitation in youth is a challenging presentation to the emergency department. In many cases, however, youth can be behaviorally de-escalated using a combination of environmental modification and verbal de-escalation. In cases where additional strategies such as pharmacologic de-escalation or physical restraint are needed, using the least restrictive means possible, including the youth in the decision-making process, and providing options are important. This paper reviews specific considerations on the approach to a youth with acute agitation and strategies and techniques to successfully de-escalate agitated youth who pose a danger to themselves and/or others.

Medial Amygdalar Tau Is Associated With Mood Symptoms in Preclinical Alzheimer's Disease.

BACKGROUND: While the amygdala receives early tau deposition in Alzheimer's disease (AD) and is involved in social and emotional processing, the relationship between amygdalar tau and early neuropsychiatric symptoms in AD is unknown. We sought to determine whether focal tau binding in the amygdala and abnormal amygdalar connectivity were detectable in a preclinical AD cohort and identify relationships between these and self-reported mood symptoms. METHODS: We examined 598 individuals (347 amyloid positive [58% female], 251 amyloid negative [62% female] subset in tau positron emission tomography and functional magnetic resonance imaging cohorts) from the A4 (Anti-Amyloid Treatment in Asymptomatic AD) Study. In the tau positron emission tomography cohort, we used amygdalar segmentations to examine representative nuclei from 3 functional divisions of the amygdala. We analyzed between-group differences in division-specific tau binding in the amygdala in preclinical AD. We conducted seed-based functional connectivity analyses from each division in the functional magnetic resonance imaging cohort. Finally, we conducted exploratory post hoc correlation analyses between neuroimaging biomarkers of interest and anxiety and depression scores. RESULTS: Amyloid-positive individuals demonstrated increased tau binding in the medial and lateral amygdala, and tau binding in these regions was associated with mood symptoms. Across amygdalar divisions, amyloid-positive individuals had relatively higher regional connectivity from the amygdala to other temporal regions, the insula, and the orbitofrontal cortex, but medial amygdala to retrosplenial cortex connectivity was lower. Medial amygdala to retrosplenial connectivity was negatively associated with anxiety symptoms, as was retrosplenial tau. CONCLUSIONS: Our findings suggest that preclinical tau deposition in the amygdala and associated changes in functional connectivity may be related to early mood symptoms in AD.

Medial amygdalar tau is associated with anxiety symptoms in preclinical Alzheimer's disease.

BACKGROUND: While the amygdala receives early tau deposition in Alzheimer's disease (AD) and is involved in social and emotional processing, the relationship between amygdalar tau and early neuropsychiatric symptoms in AD is unknown. We sought to determine whether focal tau binding in the amygdala and abnormal amygdalar connectivity were detectable in a preclinical AD cohort and identify relationships between these and self-reported mood symptoms. METHODS: We examined n=598 individuals (n=347 amyloid-positive (58% female), n=251 amyloid-negative (62% female); subset into tau PET and fMRI cohorts) from the A4 Study. In our tau PET cohort, we used amygdalar segmentations to examine representative nuclei from three functional divisions of the amygdala. We analyzed between-group differences in division-specific tau binding in the amygdala in preclinical AD. We conducted seed-based functional connectivity analyses from each division in the fMRI cohort. Finally, we conducted exploratory post-hoc correlation analyses between neuroimaging biomarkers of interest and anxiety and depression scores. RESULTS: Amyloid-positive individuals demonstrated increased tau binding in medial and lateral amygdala (F(4,442)=14.61, p=0.00045; F(4,442)=5.83, p=0.024, respectively). Across amygdalar divisions, amyloid-positive individuals had relatively increased regional connectivity from amygdala to other temporal regions, insula, and orbitofrontal cortex. There was an interaction by amyloid group between tau binding in the medial and lateral amygdala and anxiety. Medial amygdala to retrosplenial connectivity negatively correlated with anxiety symptoms (rs=-0.103, p=0.015). CONCLUSIONS: Our findings suggest that preclinical tau deposition in the amygdala may result in meaningful changes in functional connectivity which may predispose patients to mood symptoms.

Preprocedural Oxygenation and Procedural Oxygenation During Pediatric Procedural Sedation: Patterns of Use and Association With Interventions.

STUDY OBJECTIVE: Preprocedural oxygenation (pre-emptive oxygenation started during presedation and/or induction) and procedural oxygenation (pre-emptive oxygenation started during any phase of sedation) are easy-to-use strategies with potential to decrease adverse events. Here, we describe practice patterns of preprocedural oxygenation and procedural oxygenation. We hypothesized that patients who received preprocedural oxygenation or procedural oxygenation would have a lower risk of airway/breathing/circulation interventions during sedation compared with patients without procedural oxygenation. METHODS: We performed a retrospective, multicenter, cross-sectional study of pediatric sedations from April 2020 to July 2023 using the Pediatric Sedation Research Consortium multicenter database. The patient-level and sedation-level characteristics were described using frequencies and proportions, stratified by preprocedural oxygenation and procedural oxygenation status. We determined the site-level frequency of preprocedural oxygenation and procedural oxygenation use. We used inverse probability of treatment weighting to calculate the risk difference for interventions associated with preprocedural oxygenation and procedural oxygenation. RESULTS: This study included a total of 85,599 pediatric sedations; 43,242 (50.5%) patients received preprocedural oxygenation (used oxygen before sedation and/or at induction) and a total of 52,219 (61.0%) received procedural oxygenation pre-emptively at any time during the sedation. There was no statistical difference in overall interventions with either preprocedural oxygenation (risk difference -0.06%; 95% confidence interval -4.26% to 4.14%) or procedural oxygenation (risk difference -1.07%; 95% confidence interval -6.44% to 4.30%). CONCLUSION: Pre-emptive preprocedural oxygenation and procedural oxygenation were not associated with a difference in the use of airway/breathing/circulation interventions in pediatric sedations.

Association between tooth loss-related speech and psychosocial impairment with cognitive function: A pilot study in Hong Kong's older population.

BACKGROUND: Tooth loss has been associated with cognitive decline, but the underlying mechanisms involving speech and psychosocial impairment remain unclear. OBJECTIVES: To investigate the impact of tooth loss-related speech and psychosocial impairment on cognitive function in Hong Kong's older population. METHODS: Seventy-six Cantonese-speaking participants between the ages of 51-92 were classified into three groups: patients with complete dentures (CD), partially edentulous patients with less than 10 occluding tooth pairs (OU <10), and at least 10 occluding tooth pairs (OU ≥10). Cognitive function was assessed using the Montreal Cognitive Assessment Hong Kong Version, One-minute Verbal Fluency Task and Hayling Sentence Completion Test. Objective and subjective speech assessments were carried out using artificial intelligence speech recognition algorithm and a self-designed speech questionnaire. The impact of tooth loss on psychosocial condition was evaluated by the Reading the Mind in the Eyes Test and a self-designed questionnaire. Statistical analyses (one-way ANOVA, ANCOVA, Kruskal-Wallis test, Spearman correlation test) were performed. RESULTS: Tooth loss was significantly associated with lower cognitive function (p = .008), speech accuracy (p = .018) and verbal fluency (p = .001). Correlations were found between cognitive function and speech accuracy (p < .0001). No significant difference in tooth loss-related psychosocial impact was found between the three groups. CONCLUSION: While warranting larger sample sizes, this pilot study highlights the need for further research on the role of speech in the association between tooth loss and cognitive function. The potential cognitive impact of tooth retention, together with its known biological and proprioceptive benefits, supports the preservation of the natural dentition.

Determination, categorization, and hierarchy of content for a pediatric emergency medicine curriculum designed for emergency medicine residents.

Background: Currently, the Accreditation Council of Graduate Medical Education requires time-based pediatric experiences for emergency medicine (EM) residents in both pediatric emergency medicine (PEM) and critical care settings. The American Board of Emergency Medicine has published the Model of the Clinical Practice of Emergency Medicine, which is a list of content an EM resident should learn. However, this list is large and without prioritization and therefore can be difficult to incorporate into time-limited curricula. Objectives: The primary objective of this study was to develop comprehensive categorization of PEM content using an EM lens. The second objective was to suggest a prioritization for the EM learner of the enumerated PEM elements. Methods: We first assembled a comprehensive list of PEM concepts, diagnoses, and procedures that might be taught to EM residents. We then convened focus groups composed of key stakeholders to help formulate content and concept themes important for EM resident training. Once the themes were identified, we divided the list of PEM topics into appropriate themes and then carried out a second round of focus groups expanded to include more diverse expert input for prioritizing the elements of the comprehensive list within each theme. Results: We prioritized 168 important PEM concepts from previous standards and emerging PEM literature among 10 identified themes: the pediatric normal, the bottom-line boil-it-down approach, common presentations, high-acuity pediatric cases and procedures, differences between children and adults, same between children and adults, red flags, infrequency of caring for a child compared with an adult, keep breadth but promote self-directed depth, and triage and disposition. Conclusions: Based on input from stakeholders in EM resident education, we identified key themes within PEM education and created a framework for the hierarchical categorization of PEM content for within an EM residency.

Effect of Antiresorptive Drugs on Osseointegrated Dental Implants: A Systematic Review.

Background: This systematic review aimed to evaluate the impact of antiresorptive drug therapy on osseointegrated dental implants and the association with medication-related osteonecrosis of the jaw (MRONJ). Methods: A systematic search, including a computer search of several databases with specific keywords, a reference search, and a manual search of four key maxillofacial journals were performed. Relevant articles were then evaluated and those that fulfilled the five predetermined criteria were chosen to enter the final review. A total of 445 implants in 135 subjects were included in the eight studies analyzed in the final review. Results: The failure rate of dental implants after antiresorptive medication in the included studies was 23%, with 83% of failures attributed to MRONJ. The average time from antiresorptive drug initiation to MRONJ development was approximately 34 months, ranging from 3 months to 16 years. The majority of MRONJ cases were classified as stage 2, and all sites showed either complete healing or substantial mucosal coverage after treatment. Conclusions: This review highlights the significant impact of antiresorptive drugs on osseo- integrated implants, with MRONJ identified as a leading cause of implant failure. The potential role of peri-implantitis as a trigger for MRONJ is emphasized. Regular monitoring and maintaining good periodontal health, especially within the first three years of antiresorptive drug therapy initiation, are crucial for implant success. Physicians and dentists should provide comprehensive information to patients prescribed with antiresorptive drugs, emphasizing the need for an awareness of the risks of MRONJ in the context of osseointegrated implants. A longer term of follow-up is recommended to identify and manage MRONJ around dental implants in an early manner.

Approach to acute agitation in the pediatric emergency department.

PURPOSE OF REVIEW: The complexity of pediatric mental and behavioral health (MBH) complaints presenting to emergency departments (EDs) is increasing at an alarming rate. Children may present with agitation or develop agitation during the ED visit. This causes significant distress and may lead to injury of the child, caregivers, or medical staff. This review will focus on providing safe, patient-centered care to children with acute agitation in the ED. RECENT FINDINGS: Approaching a child with acute agitation in the ED requires elucidation on the cause and potential triggers of agitation for optimal management. The first step in a patient-centered approach is to use the least restrictive means with behavioral and environmental strategies. Restraint use (pharmacologic or physical restraint) should be reserved where these modifications do not result in adequate de-escalation. The provider should proceed with medications first, using the child's medication history as a guide. The use of physical restraint is a last resort to assure the safety concerns of the child, family, or staff, with a goal of minimizing restraint time. SUMMARY: Children are increasingly presenting to EDs with acute agitation. By focusing primarily on behavioral de-escalation and medication strategies, clinicians can provide safe, patient-centered care around these events.

Humanistic burden of mucopolysaccharidoses: a systematic literature review.

OBJECTIVE: To systematically review the literature and summarize the health-related quality-of-life (HRQoL) of patients undergoing treatment for mucopolysaccharidoses (MPS), a rare, hereditary lysosomal storage disorder. METHODS: A systematic review was performed in accordance with PRISMA guidelines to identify research studies that describe the humanistic burden of MPS. A comprehensive literature search was conducted in EMBASE, MEDLINE, and eligible conferences were screened to include applicable abstracts. RESULTS: Of 870 identified articles, 15 studies reported the HRQoL burden of patients with MPS undergoing or with a history of ERT and/or HSCT. These studies include patients of MPS I (n = 2), MPS II (n = 4), MPS IV (n = 6), MPS VI (n = 1), and subtype not mentioned (n = 2). Although the quality-of-life of MPS patients is influenced by time of diagnosis, pain, cognitive involvement, severity of disease, mobility, dependence, and time of treatment initiation, the HRQoL scores of MPS patients across all the scales were below the median reference population scores across all dimensions. This is seen in comparison to healthy participants but also in comparison to patients with other chronic illnesses. The multi-organ involvement, neurological impairment, pain, and morbidity associated with the condition not only affects activity of daily living but also affects social functioning, emotional status, employment status among adults, and school functioning among children. CONCLUSIONS: This systematic literature review revealed the substantial humanistic burden of individuals affected by MPS as well as caregivers. Significant variation in HRQoL scores was observed, however studies indicate that the quality-of-life of MPS patients is influenced primarily by severity of disease (MPS type and phenotype), and then by time of diagnosis, pain, cognitive involvement, mobility, dependence, and time of treatment initiation. Further studies are needed to assess the global humanistic burden of MPS, particularly in MPS III, VI, VII, and IX subtypes, in adults, and for a longer follow-up period. Considering the vast array of HRQoL assessment tools available and used in this study, researchers should also consider using scales with condition-specific measures to ensure appropriate estimates of effectiveness.

Oral Health Status and Oral Health-Related Behaviours of Hong Kong Students with Vision Impairment.

This cross-sectional epidemiological study aimed to describe dental caries and oral hygiene conditions among visually impaired students in Hong Kong. Students aged 6-21 years from two specialised schools for those with vision impairment were invited. Information on sociodemographic background and oral health-related behaviours was collected through an online parent-reported questionnaire. Dental caries and oral hygiene were assessed using the Decayed, Missing and Filled Teeth (DMFT) index and the Visible Plaque Index (VPI), respectively. Chi-square, Mann-Whitney U and Kruskal-Wallis H tests were conducted to analyse the association between students' background and oral health status. A total of 73 participants were recruited, of whom 57.5% were male. Their mean (SD) age was 12.9 (4.7) years. Their mean DMFT score (SD) was 1.0 (1.8), and 43.8% had caries experience. The mean VPI (SD) was 0.76 (0.30). Their caries experience was significantly associated with their snacking habits (p = 0.013). Male participants had poorer oral hygiene than females (p = 0.048). In summary, dental caries is prevalent among visually impaired students in Hong Kong and their oral hygiene condition is unsatisfactory. Caries experience is significantly associated with snacking frequency, whereas oral hygiene is associated with gender. More specially designed preventive oral health measures should be provided for visually impaired students and their caretakers.

Alternative care sites and resident exposure in pediatric emergency medicine: Who, what, and where.

Objectives: Emergency medicine (EM) physicians and pediatricians who provide acute pediatric care depend on clinical exposure during residency to learn pediatric EM. Increasing volumes of pediatric patients, especially with behavioral health complaints, have stressed pediatric emergency departments (ED) and prompted clinical operations innovations including alternative care sites outside the main ED. We investigated the impact of these recent trends and resulting alternative care sites on the exposure of residents to core pediatric conditions. Methods: This retrospective study reviewed patient encounters between July 1, 2018, and December 31, 2022, at a pediatric ED that hosts one pediatric and three EM residencies. During the study, the hospital employed alternative care sites in response to increased and shifting patient populations. Median patients per resident per academic year were compared before and after the opening of alternative care sites, overall and stratified by patient factors (age, sex, Emergency Severity Index [ESI], and diagnostic category). The study also compared the percentage of residents who saw no patients with a given diagnosis between the two periods. Results: Of 231,101 patient encounters, 199,947 were seen in the main ED and 31,154 in alternative care sites. The median number of patients seen by a single resident in a single academic year ranged from 82 to 136 for pediatric residents and from 128 to 183 for EM residents. The median number of patients per resident per year did not decrease for any age group, sex, ESI level, or diagnosis across the two periods. Residents saw a median of 19 more patients with psychiatric diagnoses (95% CI 15.4-22.7) in the more recent period. Seven diagnoses were not seen by at least 20% of residents during both periods. Conclusions: Current pediatric ED capacity challenges can be addressed with alternative care sites without decreasing volume or variety of patients seen by residents.

Critical Revisits Among Children After Emergency Department Discharge.

STUDY OBJECTIVE: Identifying higher risk groups could reveal ways to prevent critical emergency department (ED) revisits. The study objectives were to determine the rate of critical ED revisits among children discharged from the ED and to identify factors associated with critical revisits. METHODS: We performed a retrospective study using the Healthcare Cost and Utilization Project State ED Databases (SEDD) and the State Inpatient Databases (SID). We included data from 6 states from 2014 through 2017. Critical ED revisit was defined as either ICU admission or death within 3 days of the initial ED discharge. We included all patients younger than 21 years. The main outcome was the rate of critical ED revisit. We also determined the relative risk (RR) of a critical ED revisit for the most common index ED visit diagnoses. We used negative binomial regression to calculate incidence rate ratios (IRR) of a critical ED visit by pediatric volume and complex chronic conditions. RESULTS: A total of 16.3 million children were discharged from an ED over the 4-year study period. There were 18,704 (0.1%) critical ED revisits, 180 (0.00001%) of whom died. Asthma (RR 2.24, 95% confidence interval [CI] [2.11 to 2.38) had the highest relative risk of a critical revisit among all ED diagnoses. Adjusting for hospital volume and patient age, patients with complex chronic conditions were also more likely to have a critical ED revisit (IRR 11.03, 95% CI, 7.76 to 15.67). CONCLUSIONS: Critical revisits after ED discharge were uncommon among children in our study sample, with revisits resulting in patient death within 3 days of an ED discharge being rare. Given the short time interval between ED discharges, however, future research should focus on understanding higher risk patients among those with asthma and a history of complex chronic conditions.

Pediatric emergency care coordinator workforce: A survey study.

Objectives: The appointment of pediatric emergency care coordinators (PECC) in emergency departments (EDs) enhances pediatric readiness, yet little is understood regarding this workforce. We describe PECC role characteristics, responsibilities, barriers, and threats to the role among a national cohort. Methods: We surveyed a sample of PECCs from all regions of the United States who participated in the Emergency Medical Services for Children PECC Workforce and Trauma Collaboratives (2021-2022). EDs were categorized by annual pediatric patient volume: low (<1800), medium (1800-4999), medium-high (5000-9999), and high (≥10,000). Trend tests were performed to explore the relationship between pediatric volume and PECC characteristics. Results: Among 187 PECCs, 114 (61.0%) responded. The majority (75.2%) identified as a nurse. There was a significant difference in median hours per week spent on PECC activities by pediatric volume ranging from a median of 2 hours (interquartile range [IQR] 0.0-2.3) for low pediatric volume to 16 hours (IQR 4.0-37.0) for high pediatric volume (P < 0.001). Most respondents reported more time was needed for PECC activities (58.4%), and desired additional training to support the role (70.8%). Most (74.6%) felt the PECC position should be paid, yet 30.7% reported the role was voluntary. The most frequently assigned responsibilities were education of staff (77.2%) and oversight of quality improvement (QI) efforts (72.8%). Conclusion: Characteristics of PECC workforce vary but PECC activities of education and QI work are common among all. There is a reported need for additional training and support. Further studies will determine the impact of PECC characteristics on pediatric readiness.

Exploring physician gender bias in the initiation of prescribing cascades for older men and women: a qualitative clinical vignette study protocol.

INTRODUCTION: A prescribing cascade occurs when a drug is prescribed to manage the often unrecognised side effect of another drug; these cascades are of particular concern for older adults who are at heightened risk for drug-related harm. It is unknown whether, and to what extent, gender bias influences physician decision-making in the context of prescribing cascades. The aim of this transnational study is to explore the potential impact of physician implicit gender biases on prescribing decisions that may lead to the initiation of prescribing cascades in older men and women in two countries, namely: Canada and Italy. METHODS AND ANALYSIS: Male and female primary care physicians at each site will be randomised 1:1 to a case vignette that features either a male or female older patient who presents with concerns consistent with the side effect of a medication they are taking. During individual interviews, while masked to the true purpose of the study, participants will read the vignette and use the think-aloud method to describe their ongoing thought processes as they consider the patient's concerns and determine a course of action. Interviews will be recorded, transcribed verbatim and thematic analysis will be conducted to highlight differences in decisions in the interviews/transcripts, using a common analytical framework across the sites. ETHICS AND DISSEMINATION: This study has received ethics approval at each study site. Verbal informed consent will be received from participants prior to data collection and all data will be deidentified and stored on password-protected servers. Results of this study will be disseminated through peer-reviewed journal articles and presented at relevant national and international conferences.

The influence of the "cancer" label on perceptions and management decisions for low-grade prostate cancer.

BACKGROUND: Grade Group 1 (GG1) prostate cancer should be managed with active surveillance (AS). Global uptake of AS remains disappointingly slow and heterogeneous. Removal of cancer labels has been proposed to reduce GG1 overtreatment. We sought to determine the impact of GG1 disease terminology on individual's perceptions and decision making. METHODS: Discrete choice experiments were conducted on 3 cohorts: healthy men, canonical partners (partners), and patients with GG1 (patients). Participants reported preferences in a series of vignettes with 2 scenarios each, permuting key opinion leader-endorsed descriptors: biopsy (adenocarcinoma, acinar neoplasm, prostatic acinar neoplasm of low malignant potential [PAN-LMP], prostatic acinar neoplasm of uncertain malignant potential), disease (cancer, neoplasm, tumor, growth), management decision (treatment, AS), and recurrence risk (6%, 3%, 1%, <1%). Influence on scenario selection were estimated by conditional logit models and marginal rates of substitution. Two additional validation vignettes with scenarios portraying identical descriptors except the management options were embedded into the discrete choice experiments. RESULTS: Across cohorts (194 healthy men, 159 partners, and 159 patients), noncancer labels PAN-LMP or prostatic acinar neoplasm of uncertain malignant potential and neoplasm, tumor, or growth were favored over adenocarcinoma and cancer (P < .01), respectively. Switching adenocarcinoma and cancer labels to PAN-LMP and growth, respectively, increased AS choice by up to 17%: healthy men (15%, 95% confidence interval [CI] = 10% to 20%, from 76% to 91%, P < .001), partners (17%, 95% CI = 12% to 24%, from 65% to 82%, P < .001), and patients (7%, 95% CI = 4% to 12%, from 75% to 82%, P = .063). The main limitation is the theoretical nature of questions perhaps leading to less realistic choices. CONCLUSIONS: "Cancer" labels negatively affect perceptions and decision making regarding GG1. Relabeling (ie, avoiding word "cancer") increases proclivity for AS and would likely improve public health.

Enteral administration of the protease inhibitor gabexate mesilate preserves vascular function in experimental trauma/hemorrhagic shock.

Preserving vascular function is crucial for preventing multiorgan failure and death in ischemic and low-pressure states such as trauma/hemorrhagic shock (T/HS). It has recently been reported that inhibiting circulating proteases released from the bowel to the circulation during T/HS may preserve vascular function and improve outcomes following T/HS. This study aimed to evaluate the role of the serine protease inhibitor gabexate mesilate (GM) in preserving vascular function during T/HS when given enterally. We studied the vascular reactivity of mesenteric arteries from male Wistar rats treated with enteral GM (10 mg/kg) (GM-treated, n = 6) or control (Shock-control, n = 6) following (T/HS) using pressure myography. Concentration-response curves of endothelial-dependent and endothelial-independent agonists (e.g., acetylcholine, sodium nitroprusside) ranging from 10-10 to 10-5 M were performed. In a second set of experiments, ex-vivo arteries from healthy rats were perfused with plasma from shocked animals from both groups and vascular performance was similarly measured. Arteries from the GM-treated group demonstrated a preserved concentration-response curve to the α1 adrenergic agonist phenylephrine compared to arteries from Shock-control animals (- logEC50: - 5.73 ± 0.25 vs. - 6.48 ± 0.2, Shock-control vs. GM-treated, p = 0.04). When perfused with plasma from GM-treated rats, healthy arteries exhibited an even greater constriction and sensitivity to phenylephrine (- logEC50: - 6.62 ± 0.21 vs. - 7.13 ± 0.21, Shock-control vs. GM-treated, p = 0.02). Enteral GM also preserved the endothelium-dependent vascular response to agonists following T/HS and limited syndecan-1 shedding as a marker of glycocalyx compromise (41.84 ± 9 vs. 17.63 ± 3.97 ng/mL, Shock-control vs. GM-treated, p = 0.02). Syndecan-1 cleavage was correlated with plasma trypsin-like activity (r2 = 0.9611). Enteral gabexate mesilate was able to maintain vascular function in experimental T/HS, which was reflected by improved hemodynamics (mean arterial pressure 50.39 ± 7.91 vs. 64.95 ± 3.43 mmHg, Shock-control vs. GM treated, p = 0.0001). Enteral serine protease inhibition may be a potential therapeutic intervention in the treatment of T/HS.

Availability of Pediatric Emergency Care Coordinators in US Emergency Departments in 2018.

OBJECTIVES: In 2007, the US Institute of Medicine recommended that every emergency department (ED) appoint pediatric emergency care coordinators (PECCs). Despite this recommendation, our national surveys showed that few (17%) US EDs reported at least 1 PECC in 2015. This number increased slightly to 19% in 2016 and 20% in 2017. The current study objectives were to determine the following: percent of US EDs with at least 1 PECC in 2018, factors associated with availability of at least 1 PECC in 2018, and factors associated with addition of at least 1 PECC between 2015 and 2018. METHODS: In 2019, we conducted a survey of all US EDs to characterize emergency care in 2018. Using the National ED Inventory-USA database, we identified 5514 EDs open in 2018. This survey collected availability of at least 1 PECC in 2018. A similar survey was administered in 2016 and identified availability of at least 1 PECC in 2015. RESULTS: Overall, 4781 (87%) EDs responded to the 2018 survey. Among 4764 EDs with PECC data, 1037 (22%) reported having at least 1 PECC. Three states (Connecticut, Massachusetts, and Rhode Island) had PECCs in 100% of EDs. The EDs in the Northeast and with higher visit volumes were more likely to have at least 1 PECC in 2018 (all P < 0.001). Similarly, EDs in the Northeast and with higher visit volumes were more likely to add a PECC between 2015 and 2018 (all P < 0.05). CONCLUSIONS: The availability of PECCs in EDs remains low (22%), with a small increase in national prevalence between 2015 and 2018. Northeast states report a high PECC prevalence, but more work is needed to appoint PECCs in all other regions.

A Statewide Assessment of Pediatric Emergency Care Surge Capabilities.

BACKGROUND: Pediatric surge planning is critical in the setting of decreasing pediatric inpatient capacity. We describe a statewide assessment of pediatric inpatient bed capacity, clinical care therapies, and subspecialty availability during standard and disaster operations in Massachusetts. METHODS: To assess pediatric (<18 years old) inpatient bed capacity during standard operations, we used Massachusetts Department of Public Health data from May 2021. To assess pediatric disaster capacity, therapies, and subspecialty availability in standard and disaster operations, we performed a state-wide survey of Massachusetts hospital emergency management directors from May to August 2021. From the survey, we calculated additional pediatric inpatient bed capacity during a disaster and clinical therapy and subspecialty availability during standard and disaster operations. RESULTS: Of 64 Massachusetts acute care hospitals, 58 (91%) completed the survey. Of all licensed inpatient beds in Massachusetts (n = 11 670), 19% (n = 2159) are licensed pediatric beds. During a disaster, 171 pediatric beds could be added. During standard and disaster operations, respiratory therapies were available in 36% (n = 21) and 69% (n = 40) of hospitals, respectively, with high flow nasal cannula being most common. The only surgical subspecialist available in the majority of hospitals (>50%) during standard operations is general surgery (59%, n = 34). In a disaster, only orthopedic surgery could additionally provide services in the majority hospitals (76%; n = 44). CONCLUSIONS: Massachusetts pediatric inpatient capacity is limited in a disaster scenario. Respiratory therapies could be available in more than half of hospitals in a disaster, but the majority of hospitals lack surgical subspecialists for children under any circumstance.
