Characterization of Spirulina-derived extracellular vesicles and their potential as a vaccine adjuvant.

Spirulina is an edible cyanobacterium that increasingly gaining recognition for it untapped potential in the biomanufacturing of pharmaceuticals. Despite the rapidly accumulating information on extracellular vesicles (EVs) from most other bacteria, nothing is known about Spirulina extracellular vesicles (SPEVs). This study reports the successful isolation, characterization and visualization of SPEVs for the first time and it further investigates the potential therapeutic benefits of SPEVs using a mouse model.

Navigating the Healthcare Conundrum: Leadership Perspective from a Premier Healthcare Organization in Loma Linda's Blue Zone.

Navigating the healthcare conundrum in the Blue Zone of Loma Linda, California, requires understanding the unique factors that make this region stand out in terms of health and longevity. But more important is understanding the healthcare system sustaining the Blue Zone in Loma Linda, California. In an era marked by soaring healthcare costs and diminishing reimbursement rates, hospitals and physicians face an unprecedented challenge: providing excellent patient care while maintaining financial sustainability.

Targeting a highly repetitive genomic sequence for sensitive and specific molecular detection of the filarial parasite Mansonella perstans from human blood and mosquitoes.

Background: Mansonella perstans is among the most neglected of the neglected tropical diseases and is believed to cause more human infections than any other filarial pathogen in Africa. Based largely upon assumptions of limited infection-associated morbidity, this pathogen remains understudied, and many basic questions pertaining to its pathogenicity, distribution, prevalence, and vector-host relationships remain unanswered. However, in recent years, mounting evidence of the potential for increased Mansonella infection-associated disease has sparked a renewal in research interest.

Integrating blue: How do we make nationally determined contributions work for both blue carbon and local coastal communities?

Blue Carbon Ecosystems (BCEs) help mitigate and adapt to climate change but their integration into policy, such as Nationally Determined Contributions (NDCs), remains underdeveloped. Most BCE conservation requires community engagement, hence community-scale projects must be nested within the implementation of NDCs without compromising livelihoods or social justice. Thirty-three experts, drawn from academia, project development and policy, each developed ten key questions for consideration on how to achieve this.

Healthcare professionals' views of a new second-level nursing associate role: A qualitative study exploring early implementation in an acute setting.

Aim: The study aimed to establish the views of a range of stakeholders about their experiences of the newly implemented nursing associate role in England and its potential to contribute to patient care.

Background: Second-level nursing roles are increasingly used internationally within the healthcare workforce. In response to registered nurse workforce deficits, a new nursing associate role has been introduced in England to augment care provided by registered nurses and enable career progression of support workers.

Healthcare professionals' perspectives on enrolled nurses, practical nurses and other second-level nursing roles: A systematic review and thematic synthesis.

Background: Significant workforce shortages and economic pressures have led to the expanded scope and reintroduction of new roles for second-level nurses in many Organization for Economic Co-operation and Development countries. Given this, there is a need to understand the emic and etic perspectives of second-level nurses, to ensure collaborative teamwork and safe patient care.

Objective: This review aimed to systematically identify, appraise, and synthesize qualitative research evidence on healthcare professionals' perspectives on second-level nursing roles in the healthcare workforce.

Healthcare students interprofessional critical event/disaster response course.

Objective: Numerous disasters confirm the need for critical event training in healthcare professions. However, no single discipline works in isolation and interprofessional learning is recognized as a necessary component. An interprofessional faculty group designed a learning curriculum crossing professional schools.

Effect of Educational Debt on Emergency Medicine Residents: A Qualitative Study Using Individual Interviews.

Study Objective: In 2001, less than 20% of emergency medicine residents had more than $150,000 of educational debt. Our emergency medicine residents anecdotally reported much larger debt loads. Surveys have reported that debt affects career and life choices.

Allosensitization does not alter post-transplant outcomes in pediatric patients bridged to transplant with a ventricular assist device.

Patients supported with a VAD are at increased risk for sensitization. We aimed to determine risk factors for sensitization as well as the impact of sensitization on post-transplant outcomes. The UNOS database (January 2004-June 2014) was used to identify patients (≤18 yrs) supported with a durable VAD.

Arrhythmia as a cardiac manifestation in MELAS syndrome.

A 44-year-old female with a diagnosis of mitochondrial myopathy, encephalopathy and stroke-like episodes (MELAS) syndrome had progressive left ventricular hypertrophy (LVH) on echocardiogram. A Holter monitor demonstrated episodes of non-sustained atrial tachycardia, a finding not been previously described in this population. This unique case of MELAS syndrome demonstrates the known associated cardiac manifestation of LVH and the new finding of atrial tachycardia which may represent the potential for subclinical arrhythmia in this population.

The flipped classroom: a modality for mixed asynchronous and synchronous learning in a residency program.

Introduction: A "flipped classroom" educational model exchanges the traditional format of a classroom lecture and homework problem set. We piloted two flipped classroom sessions in our emergency medicine (EM) residency didactic schedule. We aimed to learn about resident and faculty impressions of the sessions, in order to develop them as a regular component of our residency curriculum.

The use of a Berlin Heart EXCOR LVAD in a child receiving chemotherapy for Castleman's disease.

We present the unique case of a pediatric patient who received chemotherapy for a diagnosis of CD, while mechanically supported with a Berlin EXCOR LVAD secondary to restrictive cardiomyopathy. A four-yr-old previously healthy male with restrictive cardiomyopathy required MCS after cardiac arrest but was diagnosed with multicentric CD, a non-malignant lymphoproliferative disorder fueled by excessive IL-6 production. Treatment with IL-6 blockade (tocilizumab) every two wk and methylprednisolone had no effect on his lymph nodes or cardiac function while on temporary RotaFlow.

Autonomic dysfunction: a driving force for myocardial fibrosis in young Duchenne muscular dystrophy patients?

Cardiac manifestations of Duchenne muscular dystrophy (DMD) include progressive cardiac dysfunction and an elevated resting heart rate (HR). We hypothesized this elevated HR reflects autonomic dysfunction that can be identified by heart rate variability (HRV) analyses which will be associated with myocardial fibrosis by cardiac magnetic resonance imaging (cMR). DMD patients (N = 74) and controls (N = 17) had time and frequency domain HRV analyses calculated via Holter monitoring.

The Development of a Physician Vitality Program: A Brief Report.

We describe the development of an innovative program to support physician vitality. We provide the context and process of program delivery which includes a number of experimental support programs. We discuss a model for intervention and methods used to enhance physician resilience, support work-life balance, and change the culture to one that explicitly addresses the physician's biopsychosocial-spiritual needs.

Prompt recognition and percutaneous coronary intervention leads to favorable myocardial recovery after ST-segment elevation myocardial infarction secondary to acute promyelocytic leukemia: pediatric case report.

Acute myocardial infarction (AMI) is extremely rare in children, and unlike the adult disease, the etiology of the infarction is rarely due to atherosclerotic coronary disease. This unique reported case involved a 15-year-old boy with severe chest pain who presented with an ST-segment-elevation myocardial infarction secondary to in situ thrombus formation in the left anterior descending (LAD) coronary artery. The initial electrocardiogram (ECG) had a Q-wave pattern in V6 and ST depression in the inferior leads with ST-segment elevation in reciprocal leads.

Starting out-training in Finland made me crave starting out greater responsibility in the UK.

On a recent three-month educational exchange programme in Finland, I was intrigued by the differences in the opportunities offered to nursing students between Finland and the UK.

Correlation of heart rate and cardiac dysfunction in Duchenne muscular dystrophy.

Sinus tachycardia is common in cases of Duchenne muscular dystrophy (DMD). The authors hypothesized that an elevated heart rate would herald cardiomyopathy onset. A retrospective case-control study was performed with 55 DMD boys and 150 age-matched control boys.

Clinical policy: Critical issues in the evaluation and management of adult patients presenting to the emergency department with acute headache.

This clinical policy from the American College of Emergency Physicians is an update of a 2002 clinical policy on the evaluation and management of adult patients presenting to the emergency department (ED) with acute, nontraumatic headache. A writing subcommittee reviewed the literature to derive evidence-based recommendations to help clinicians answer the following 5 critical questions: (1) Does a response to therapy predict the etiology of an acute headache? (2) Which patients with headache require neuroimaging in the ED? (3) Does lumbar puncture need to be routinely performed on ED patients being worked up for nontraumatic subarachnoid hemorrhage whose noncontrast brain computed tomography (CT) scans are interpreted as normal? (4) In which adult patients with a complaint of headache can a lumbar puncture be safely performed without a neuroimaging study? (5) Is there a need for further emergent diagnostic imaging in the patient with sudden-onset, severe headache who has negative findings in both CT and lumbar puncture? Evidence was graded and recommendations were given based on the strength of the available data in the medical literature.

Mass-casualty triage: time for an evidence-based approach.

Mass-casualty triage has developed from a wartime necessity to a civilian tool to ensure that constrained medical resources are directed at achieving the greatest good for the most number of people. Several primary and secondary triage tools have been developed, including Simple Treatment and Rapid Transport (START), JumpSTART, Care Flight Triage, Triage Sieve, Sacco Triage Method, Secondary Assessment of Victim Endpoint (SAVE), and Pediatric Triage Tape. Evidence to support the use of one triage algorithm over another is limited, and the development of effective triage protocols is an important research priority.

International emergency medicine and the role for academic emergency medicine.

International emergency medicine continues to grow and expand. There are now more than 30 countries that recognize emergency medicine as a specialty. As the field continues to develop, many physicians are reaching across borders and working with their colleagues to improve patient care, education, and research.
