Telehealth in emergency medicine residency training: A model curriculum.

Emergency physicians are well-positioned to take a leadership role in telehealth, particularly in emerging categories such as triage, direct acute unscheduled care, and virtual observation. However, the growth of telehealth has outpaced curricular development in emergency medicine (EM) residency programs. This manuscript presents a model longitudinal telehealth curriculum, developed by the consensus of education experts, including representatives from the telehealth interest groups from EM's two primary specialty societies: the American College of Emergency Physicians and the Society for Academic Emergency Medicine.

Prospective Randomized Trial Comparing 2 Devices for Deep Inspiration Breath Hold Management in Breast Radiation Therapy: Results of the BRAVEHeart Trial.

Purpose: The Breast Radiotherapy Audio Visual Enhancement for sparing the Heart (BRAVEHeart) trial prospectively randomized patients with left-sided breast cancer to 1 of 2 deep inspiration breath hold biofeedback devices: a novel chest surface tracking system and an abdominal block tracking system. The primary hypothesis was that the accuracy of chest tracking would be higher than that of abdominal tracking as the chest is a more direct surrogate of the breast target.

Methods And Materials: Patients with left-sided breast cancer were treated in deep inspiration breath hold with intensity modulated radiation therapy delivery.

Serological Evidence of Bactrian Camel Infection with Tamdy Virus, Xinjiang, China.

Tamdy Virus (TAMV) is a pathogenic nairovirus widely distributed in central Asia and northwestern China. However, the host range of TAMV remains unclear, which limits our understanding the transmission cycle and cross-species patterns of this virus. A total of 160 serum samples were collected from livestock animals of camels, cattle, and sheep in Xinjiang, China between 2018 and 2021.

SARS-CoV-2 Seropositivity in Urban Population of Wild Fallow Deer, Dublin, Ireland, 2020-2022.

SARS-CoV-2 can infect wildlife, and SARS-CoV-2 variants of concern might expand into novel animal reservoirs, potentially by reverse zoonosis. White-tailed deer and mule deer of North America are the only deer species in which SARS-CoV-2 has been documented, raising the question of whether other reservoir species exist. We report cases of SARS-CoV-2 seropositivity in a fallow deer population located in Dublin, Ireland.

Identification and phylogenetic analysis of Nairobi sheep disease virus from Haemaphysalis longicornis ticks in Shandong Province, China.

Nairobi Sheep Disease (NSD) is a typical tick-borne syndrome characterized by severe hemorrhagic gastroenteritis, spontaneous abortion, and a high case fatality rate in small ruminants. The pathogenic agent, Nairobi sheep disease virus (NSDV), has also been associated with human infections, indicating its possible zoonotic potential. Prior to this study, NSDV has been detected from ticks collected in Jilin, Hubei, and Liaoning provinces in China.

Isolation and characterization of a novel rodent hepevirus in long-tailed dwarf hamsters () in China.

Hepeviruses have been identified in a broad range of animal hosts, including mammals, birds, and fish. In this study, rodents (=91) from seven different species and ten pikas () were collected in Qinghai Province, China. Using transcriptomic sequencing and confirmatory molecular testing, hepeviruses were detected in 27 of 45 (60 %) long-tailed dwarf hamsters () and were undetected in other rodents and pika.

Doxycycline inhibits neurotropic enterovirus proliferation in vitro.

Human enteroviruses (EVs) represent a global public health concern due to their association with a range of serious pediatric illnesses. Despite the high morbidity and mortality exerted by EVs, no broad-spectrum antivirals are currently available. Herein, we presented evidence that doxycycline can inhibit in vitro replication of various neurotropic EVs, including enterovirus A71 (EV-A71), enterovirus D68 (EV-D68), and coxsackievirus (CV)-A6, in a dose-dependent manner.

Multiple introductions of monkeypox virus to Ireland during the international mpox outbreak, May 2022 to October 2023.

BackgroundMpox, caused by monkeypox virus (MPXV), was considered a rare zoonotic disease before May 2022, when a global epidemic of cases in non-endemic countries led to the declaration of a Public Health Emergency of International Concern. Cases of mpox in Ireland, a country without previous mpox reports, could reflect extended local transmission or multiple epidemiological introductions.AimTo elucidate the origins and molecular characteristics of MPXV circulating in Ireland between May 2022 and October 2023.

Coronary Artery Aneurysms Following Repair of Transposition of the Great Arteries.

• Periodic surveillance after ASO for TGA with multimodality imaging is recommended. • New aneurysms may be detected in patients with antecedent KD. • KD should be suspected in patients with CAA even without previously known illness.

Ketones provide an extra source of fuel for the failing heart without impairing glucose oxidation.

Background: Cardiac glucose oxidation is decreased in heart failure with reduced ejection fraction (HFrEF), contributing to a decrease in myocardial ATP production. In contrast, circulating ketones and cardiac ketone oxidation are increased in HFrEF. Since ketones compete with glucose as a fuel source, we aimed to determine whether increasing ketone concentration both chronically with the SGLT2 inhibitor, dapagliflozin, or acutely in the perfusate has detrimental effects on cardiac glucose oxidation in HFrEF, and what effect this has on cardiac ATP production.

A Reference Equation for Peak Oxygen Uptake for Pediatric Patients Who Undergo Treadmill Cardiopulmonary Exercise Testing.

Pediatric patients are often referred to cardiopulmonary exercise testing (CPET) laboratories for assessment of exercise-related symptoms. For clinicians to understand results in the context of performance relative to peers, adequate fitness-based prediction equations must be available. However, reference equations for prediction of peak oxygen uptake (VO) in pediatrics are largely developed from field-based testing, and equations derived from CPET are primarily developed using adult data.

Tricuspid Atresia with Absent Pulmonary Valve with Nearly Discontinuous Branch Pulmonary Arteries.

Absent pulmonary valve with tricuspid atresia or tricuspid stenosis (APV-TA/TS) is an extremely rare congenital heart defect associated with significant morbidity and mortality. Compared to Tetralogy of Fallot with Absent Pulmonary Valve Syndrome, branch pulmonary arteries are not typically significantly dilated. We present the case of a newborn male prenatally diagnosed APV-TA with intact ventricular septum (IVS) and nearly discontinuous branch pulmonary arteries, the surgical strategy employed, and the salient hemodynamic factors considered in the medical decision-making.

Grade of Primary Cutaneous Leiomyosarcoma Dictates Risk for Metastatic Spread and Disease-Specific Mortality.

Background And Objectives: Primary cutaneous leiomyosarcoma (cLMS), a rare, typically intradermal tumor, has previously been reported to exhibit an indolent course of disease with zero-to-low risk of local recurrence or distant metastasis. This study seeks to evaluate recurrence and survival of cLMS patients through study of its clinicopathologic and treatment characteristics.

Methods: All patients included underwent resection of primary cLMS at this institution between 2006 and 2019.

Reference Values for Cardiorespiratory Fitness in Patients Aged 6 to 18 Years.

Objective: To develop reference values for cardiorespiratory fitness, as quantified by peak oxygen uptake (VO) and treadmill time, in patients aged 6 through 18 years referred for cardiopulmonary exercise testing (CPET).

Study Design: We reviewed a clinical pediatric CPET database for fitness data in children aged 6-18 years with no underlying heart disease. CPET was obtained via the Bruce protocol utilizing objectively confirmed maximal effort via respiratory exchange ratio.

Circulation of influenza C virus of C/Sao Paulo/378/82 lineage among pediatric acute respiratory cases, Shandong, China.

Influenza C virus (ICV) was identified in five pediatric acute respiratory cases in Shandong. Co-infection with other respiratory viruses was detected in four of these cases. Two ICV genomes were obtained and clustered in the S1-sublineage of C/Sao Paulo/378/82, indicating that genetically diverse ICV strains have been circulating in mainland China.

Managing valvular pathology during LVAD implantation.

Since the time of their invention, implantable continuous flow left ventricular assist devices (LVADs) have improved the quality of life and extended survival for patients with advanced heart failure. The decision surgeons and their physician colleagues make with these patients to undergo implantation must come with full understanding of the immediate, short-term, and long-term implications of such a life-changing procedure. The presence of pathology regarding the aortic, mitral, and tricuspid valves introduces particularly complex problems for the surgical treatment strategy.

Multisystem Inflammatory Syndrome in Children (MIS-C): Reduced Exercise Duration and Capacity at Six Month Follow-Up.

Myocarditis is common in Multisystem Inflammatory Syndrome in Children (MIS-C), and the mechanism may differ from idiopathic/viral myocarditis as MIS-C involves a hyper-inflammatory state weeks after COVID-19. We sought to evaluate exercise stress testing (EST) in these patients as EST may help guide return-to-play recommendations. Retrospective cohort study evaluating ESTs (standard Bruce treadmill protocol) from MIS-C patients from 2020 to 2022, compared to myocarditis patients and age, sex, and weight matched controls from 2005 to 2019.

Breast Conservation Surgery and Mastectomy Have Similar Locoregional Recurrence After Neoadjuvant Chemotherapy: Results From 1462 Patients on the Prospective, Randomized I-SPY2 Trial.

Neoadjuvant chemotherapy (NAC) increases rates of successful breast-conserving surgery (BCS) in patients with breast cancer. However, some studies suggest that BCS after NAC may confer an increased risk of locoregional recurrence (LRR). We assessed LRR rates and locoregional recurrence-free survival (LRFS) in patients enrolled on I-SPY2 (NCT01042379), a prospective NAC trial for patients with clinical stage II to III, molecularly high-risk breast cancer.

Dysregulated early transcriptional signatures linked to mast cell and interferon responses are implicated in COVID-19 severity.

Background: Dysregulated immune responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are thought to underlie the progression of coronavirus disease 2019 (COVID-19) to severe disease. We sought to determine whether early host immune-related gene expression could predict clinical progression to severe disease.

Methods: We analysed the expression of 579 immunological genes in peripheral blood mononuclear cells taken early after symptom onset using the NanoString nCounter and compared SARS-CoV-2 negative controls with SARS-CoV-2 positive subjects with mild (SARS+ Mild) and Moderate/Severe disease to evaluate disease outcomes.

SFTSV infection is associated with transient overproliferation of monoclonal lambda-type plasma cells.

The impairment of antibody-mediated immunity is a major factor associated with fatal cases of severe fever with thrombocytopenia syndrome (SFTS). By collating the clinical diagnosis reports of 30 SFTS cases, we discovered the overproliferation of monoclonal plasma cells (MCP cells, CD38cLambdacKappa) in bone marrow, which has only been reported previously in multiple myeloma. The ratio of CD38cLambda versus CD38cKappa in SFTS cases with MCP cells was significantly higher than that in normal cases.

Assessing the Efficacy of Imiquimod Use in Patients With Persistent Locally Advanced Melanoma In Situ.

Background: The standard of care when treating melanoma in situ (MMIS) is an excision with at least 5 mm surgical margins.1 Some studies have suggested up to 9 mm margins to maximize local recurrence-free survival.2 This retrospective review aims to assess the efficacy of imiquimod as a topical treatment for persistently positive MMIS at the margins of prior excisions or where surgery is not an option.

Prevalence of Abnormal Hemoglobin A1c Values in Single Ventricle Patients Following Fontan Palliation.

Fontan palliation has improved survival in single ventricle patients. However, Fontan patients are subject to long-term morbidity. A few previous studies suggest Fontan patients have an increased risk of abnormal glucose metabolism without a clear mechanism.

Adeno-Associated Virus 2 and Human Adenovirus F41 in Wastewater during Outbreak of Severe Acute Hepatitis in Children, Ireland.

During April-July 2022, outbreaks of severe acute hepatitis of unknown etiology (SAHUE) were reported in 35 countries. Five percent of cases required liver transplantation, and 22 patients died. Viral metagenomic studies of clinical samples from SAHUE cases showed a correlation with human adenovirus F type 41 (HAdV-F41) and adeno-associated virus type 2 (AAV2).
