ABSTRACT

Existing acute febrile illness (AFI) surveillance systems can be leveraged to identify and characterize emerging pathogens, such as SARS-CoV-2, which causes COVID-19. The US Centers for Disease Control and Prevention collaborated with ministries of health and implementing partners in Belize, Ethiopia, Kenya, Liberia, and Peru to adapt AFI surveillance systems to generate COVID-19 response information. Staff at sentinel sites collected epidemiologic data from persons meeting AFI criteria and specimens for SARS-CoV-2 testing. A total of 5,501 patients with AFI were enrolled during March 2020-October 2021; >69% underwent SARS-CoV-2 testing. Percentage positivity for SARS-CoV-2 ranged from 4% (87/2,151, Kenya) to 19% (22/115, Ethiopia). We show SARS-CoV-2 testing was successfully integrated into AFI surveillance in 5 low- to middle-income countries to detect COVID-19 within AFI care-seeking populations. AFI surveillance systems can be used to build capacity to detect and respond to both emerging and endemic infectious disease threats.

ABSTRACT

BACKGROUND: Respiratory-related complaints prompt most pediatric visits to Karl Heusner Memorial Hospital Authority's (KHMHA) Emergency Department (ED) in Belize. We developed and taught a novel pediatric respiratory emergencies module for generalist practitioners there. We assessed the curriculum's clinical impact on pediatric asthma emergency management. OBJECTIVE: This study assesses the clinical impact of a pediatric emergency medicine curriculum on management of pediatric asthma emergencies at KHMHA in Belize City, Belize. METHODS: We conducted a randomized chart review of pediatric (aged 2-16 y) visits for asthma-related diagnosis at the KHMHA ED between 2015 and 2018 to assess the training module's clinical impact. Primary outcomes included time to albuterol and steroids. Secondary outcomes included clinical scoring tool (Pediatric Respiratory Assessment Measure [PRAM]) usage, ED length of stay, usage of chest radiography, return visit within 7 days, and hospital admission rates. Kaplan-Meier survival analysis and Cox proportional hazard regression were used. RESULTS: Two hundred eighty-three pediatric asthma-related diagnoses met our inclusion criteria. The patients treated by trained and untrained physician groups were demographically and clinically similar. The time to albuterol was significantly faster in the trained (intervention) group compared with the untrained (control) physician group when evaluating baseline of the group posttraining (P < 0.05). However, the time to steroids did not reach statistical significance posttraining (P = 0.93). The PRAM score utilization significantly increased among both control group and intervention group. The untrained physician group was more likely to use chest radiography or admit patients. The trained physician group had higher return visit rates within 7 days and shorter ED length of stay, but this did not reach statistical significance. CONCLUSIONS: The curriculum positively impacted clinical outcomes leading to earlier albuterol administration, increased PRAM score use, obtaining less chest radiographs, and decreased admission rates. The timeliness of systemic steroid administration was unaffected.

ABSTRACT

Objective. Triage in resource-limited settings (RLS) improves outcomes. Emergency Triage Assessment and Treatment (ETAT) is a simple triage algorithm that improves assessment and initial management of children in RLS. In Belize, pediatric triage varies with setting, from a 5-level Emergency Severity Index (ESI) used at the National Referral Hospital to a lack of triage at government health centers (GHC). Most data on ETAT implementation are in settings where no triage system existed; data on how to integrate ETAT into existing, heterogeneous triage systems are lacking. The aim of this study is to explore health care providers' (HCPs) attitudes toward the current triage system prior to national pediatric triage process implementation. Methods. A qualitative study was performed via convenience sampling of HCPs who participated in an ETAT training course using focus groups immediately and 1 year after an initial ETAT training. Focus groups were digitally recorded and transcribed. Three coders analyzed all transcripts to identify emerging themes. Constant comparison analysis was performed until achieving thematic saturation. Results. The following principal themes emerged: (1) importance of triage education and implementation to standardize and improve communication; (2) major limitations of ESI include its complexity, lack of pediatric-specific criteria, and dependence on equipment not consistently available; and (3) desire to implement a simple, low-resource pediatric-specific triage system. Conclusions. Participants believe triage education and process implementation is essential to improve communication and pediatric emergency care. Simple, low-resource pediatric-specific triage systems, like ETAT, may improve utilization by providing faster recognition and improved care for acutely ill children.

ABSTRACT

Mental health disorders are a major cause of morbidity and a growing burden in low-income and middle-income countries; but there is little existing literature on the detailed epidemiology, diagnosis, and treatment in low-resource settings. Special situations with vulnerable populations, such as those created by international humanitarian emergencies, refugees or internally displaced people, and victims of human trafficking, are increasing in prevalence. These victims are often resettled in developed countries and come to the emergency department seeking care. To better care for these populations, knowledge of specialized psychosocial and cultural considerations should inform the comprehensive psychiatric assessment and treatment plan.

ABSTRACT

OBJECTIVES: There are many barriers impeding the conduct of high-quality emergency care research, particularly in low- and middle-income countries. Several of these barriers were originally outlined in 2013 as part of the Academic Emergency Medicine Global Health and Emergency Care Consensus Conference. This paper seeks to establish a broader consensus on the barriers to emergency care research globally and proposes a comprehensive array of new recommendations to overcome these barriers. METHODS: An electronic survey was conducted of a purposive sample of global emergency medicine research experts from around the world to describe the major challenges and solutions to conducting emergency care research in low-resource settings and rank them by importance. The Global Emergency Medicine Think Tank Clinical Research Working Group at the Society for Academic Emergency Medicine 2016 Annual Meeting utilized a modified Delphi technique for consensus-based decision making to categorize and expand upon these barriers and develop a comprehensive array of proposed solutions. RESULTS: The working group identified four broad categories of barriers to conducting emergency care research globally, including 1) the limited availability of research personnel, particularly those with prior research training; 2) logistic barriers and lack of standardization of data collection; 3) ethical barriers to conducting research in resource-limited settings, particularly when no local institutional review board is available; and 4) the relative dearth of funding for global emergency care research. Proposed solutions included building a diverse and interdisciplinary research team structured to promote mentorship of junior researchers, utilizing local research assistants or technologic tools such as telemedicine for language translation, making use of new tools such as mobile health (mHealth) to standardize and streamline data collection, identifying alternatives to local institutional review board approval and the use of community consent when appropriate, and increased advocacy for global emergency care research funding. CONCLUSIONS: Significant barriers to the conduct of high-quality global emergency care research persist, and innovative strategies need to be adopted to promote and grow the field of global emergency care research. This paper provides a global consensus on the most important barriers identified, as well as recommendations for cost-effective strategies for overcoming these barriers with the overall goal of promoting high-quality research and improving emergency care worldwide.

ABSTRACT

The major sperm protein (MSP) motility system in nematode sperm is best known for propelling the movement of mature sperm, where it has taken over the role usually played by actin in amoeboid cell motility. However, MSP filaments also drive the extension of filopodia, transient organelles composed of a core bundle of MSP filaments, that form in the late in sperm development but are not found on crawling cells. We have reconstituted filopodial extension in vitro whereby thin bundles of MSP filaments, each enveloped by a membrane sheath at their growing end, elongated at rates up to 17 microm/min. These bundles often exceeded 500 microm in length but were comprised of filaments only 1 microm long. The reconstituted filopodia assembled in the same cell-free sperm extracts that produced MSP fibers, robust meshworks of filaments that exhibit the same organization and dynamics as the lamellipodial filament system that propels sperm movement. The filopodia and fibers that assembled in vitro both had a membranous structure at their growing end, shared four MSP accessory proteins, and responded identically to agents that alter MSP-based motility by modulating protein phosphorylation. However, filopodia grew three- to four-fold faster than fibers. The reconstitution of filopodial extension shows that, like the actin cytoskeleton, MSP filaments can adopt two architectures, bundles and meshworks, each capable of pushing against membranes to generate protrusion. The reconstitution of both forms of motility in the same in vitro system provides a promising avenue for understanding how the forces for membrane protrusion are produced.
