Staffing Patterns of Non-ACGME Fellowships with 4-Year Residency Programs: A National Survey.

Introduction: Emergency medicine (EM) is one of few specialties with variable training lengths. Hiring a three-year graduate to continue fellowship training in a department that supports a four-year residency program can lead to conflicts around resident supervision. We sought to understand hiring and clinical supervision, or staffing, patterns of non-Accreditation Council for Graduate Medical Education (ACGME) fellowships hosted at institutions supporting four-year residency programs.

[Coronary sinus reducer : Literature review and issues surrounding the France Reducer registry].

Coronary sinus Reducer implantation is a percutaneous technique used to treat patients suffering from refractory angina pectoris. The device narrows the coronary sinus, increases the back pressure in the myocardial venous system and forces redistribution of coronary blood flow from less ischemic subepicardium to the more ischemic subendocardium. Multiple clinical studies had proven its efficacy to alleviate myocardial ischemia and related symptoms, and to improve the quality of life of patients with refractory symptomatic chronic coronary artery disease for whom coronary revascularization is deemed unsuitable.

A feasibility study on AI-controlled closed-loop electrical stimulation implants.

Miniaturized electrical stimulation (ES) implants show great promise in practice, but their real-time control by means of biophysical mechanistic algorithms is not feasible due to computational complexity. Here, we study the feasibility of more computationally efficient machine learning methods to control ES implants. For this, we estimate the normalized twitch force of the stimulated extensor digitorum longus muscle on n = 11 Wistar rats with intra- and cross-subject calibration.

A consensus list of ultrasound competencies for graduating emergency medicine residents.

Objectives: Emergency ultrasound (EUS) is a critical component of emergency medicine (EM) resident education. Currently, there is no consensus list of competencies for EUS training, and graduating residents have varying levels of skill and comfort. The objective of this study was to define a widely accepted comprehensive list of EUS competencies for graduating EM residents through a modified Delphi method.

Association of a longitudinal, preclinical ultrasound curriculum with medical student performance.

Introduction: Point-of-care ultrasound (US) is used in clinical practice across many specialties. Ultrasound (US) curricula for medical students are increasingly common. Optimal timing, structure, and effect of ultrasound education during medical school remains poorly understood.

Assessment of Oropharyngeal Specimens for Discontinuation of Transmission-Based COVID-19 Precautions.

We compared oropharyngeal swab test performance with nasopharyngeal testing for discontinuation of transmission-based COVID-19 precautions. We performed a retrospective review of confirmed COVID-19-positive patients who received paired nasopharyngeal and oropharyngeal SARS-CoV-2 tests for clearance from isolation from May 4, 2020, to May 26, 2020. Using nasopharyngeal swabs as the reference standard, we calculated the sensitivity, specificity, and negative predictive value of oropharyngeal swabs.

[A case of "juvenile" self-healing cutaneous mucinosis in an adult].

Introduction: Self-healing juvenile cutaneous mucinosis (SHJCM) is a stereotypical disease in children characterized by the acute onset of subcutaneous papules and nodules on the face, dorsum of the hands and peri-articular regions that disappear spontaneously within a few months or years. A few cases have been reported in adults, but these display more heterogeneous clinical and histopathological features. Herein we report a case with a juvenile clinical presentation in an adult woman.

Polyol-Made Luminescent and Superparamagnetic β-NaYEuF@γ-FeO Core-Satellites Nanoparticles for Dual Magnetic Resonance and Optical Imaging.

Red luminescent and superparamagnetic β-NaYEuF@γ-FeO nanoparticles, made of a 70 nm-sized β-NaYEuF single crystal core decorated by a 10 nm-thick polycrystalline and discontinuous γ-FeO shell, have been synthesized by the polyol process. Functionalized with citrate ligands they show a good colloidal stability in water making them valuable for dual magnetic resonance and optical imaging or image-guided therapy. They exhibit a relatively high transverse relaxivity r = 42.

Uptake and excretion dynamics of gold nanoparticles in cancer cells and fibroblasts.

Radiotherapy is one of the main treatments used to fight cancer. A major limitation of this modality is the lack of selectivity between cancerous and healthy tissues. One of the most promising strategies proposed in this last decade is the addition of nanoparticles with high-atomic number to enhance radiation effects in tumors.

[Microcystic adnexal carcinoma: A case report].

We report a case of microcystic adnexal carcinoma in a 80-year-old woman. This is a rare malignant adnexal cutaneous tumor with glandular and follicular differentiation, rare, often asymptomatic, with late diagnosis and slow growth, locally aggressive and rarely metastatic. The distinction with other benign and malignant skin tumors is difficult.

Characterization of fiber ultrashort pulse delivery for nonlinear endomicroscopy.

In this work, we present a detailed characterization of a small-core double-clad photonic crystal fiber, dedicated and approved for in vivo nonlinear imaging endomicroscopy. A numerical and experimental study has been performed to characterize the excitation and collection efficiencies through a 5 m-long optical fiber, including the pulse duration and spectral shape. This was first done without any distal optics, and then the performances of the system were studied by using two kinds of GRIN lenses at the fiber output.

IgE serum concentration against airborne fungi in children with respiratory allergies.

Background: To evaluate total and specific E immunoglobulin (IgE) antibody concentrations in underage subjects with respiratory allergic diseases.

Methods: This study was a transversal-type study in 100 underage subjects between 4 and 14 years old, with asthma and/or allergic rhinitis. Total and specific IgE were quantified for airborne fungi in the city of São Luís, Maranhão, Brazil.

Spectral and lifetime domain measurements of rat brain tumors.

During glioblastoma surgery, delineation of the brain tumor margins is difficult because the infiltrated and normal tissues have the same visual appearance. We use a fiber-optical fluorescence probe for spectroscopic and time domain measurements to assist surgeon in differentiating the healthy and the infiltrated tissues. First study was performed on rats that were previously injected with tumorous cells.

Characterization, comparison, and choice of a commercial double-clad fiber for nonlinear endomicroscopy.

Several endomicroscope prototypes for nonlinear optical imaging were developed in the last decade for in situ analysis of tissue with cellular resolution by using short infrared light pulses. Fourier-transform-limited pulses at the tissue site are necessary for optimal excitation of faint endogenous signals. However, obtaining these transform-limited short pulses remains a challenge, and previously proposed devices did not achieve an optimal pulse delivery.
