Pediatric acute kidney injury is a condition that is underdiagnosed among children seen in the emergency department, and it has been associated with significant morbidity and mortality, including increased risk for chronic kidney disease. The most common etiologies in pediatric patients are now known to be due to hypovolemia, sepsis, shock, and cardiac dysfunction. This issue compares 3 classification systems for the diagnosis and staging of acute kidney injury and reviews the etiologies that lead to kidney injury in children...

INTRODUCTION: Prone position ventilation (PPV) has been shown to improve oxygenation and decrease pulmonary vascular resistance and mortality in patients with severe acute respiratory distress syndrome (ARDS). Whether these benefits of PPV occur similarly in acute exacerbations of interstitial lung disease (ILD) is not clear. We retrospectively explored the use of PPV in acute exacerbation with ILD versus those with severe ARDS. METHODS: Retrospective study of the application of PPV in 17 patients with acute exacerbations of ILD and in 19 patients with severe ARDS...

Electromagnetic metamaterials (MMs) and metasurfaces (MSs) are artificial media and surfaces with subwavelength separations of meta-atoms designed for anomalous manipulations of light properties. Owing to large scattering cross-sections of metallic/dielectric meta-atoms, it is possible to not only localize strong electromagnetic fields in deep subwavelength volume but also decompose and analyze incident light signal with ultracompact setup using MMs and MSs. Hence, by probing resonant spectral responses from extremely boosted interactions between analyte layer and optical MMs or MSs, sensing the variation of refractive index has been a popular and practical application in the field of photonics...

The hybrid MRI-radiotherapy machines, like the MR-linac (Elekta AB, Stockholm, Sweden) installed at the UMC Utrecht (Utrecht, The Netherlands), will be able to provide real-time patient imaging during treatment. In order to take advantage of the system's capabilities and enable online adaptive treatments, a new generation of software should be developed, ranging from motion estimation to treatment plan adaptation. In this work we present a proof of principle adaptive pipeline designed for high precision Stereotactic Body Radiation Therapy (SBRT) suitable for sites affected by respiratory motion, like Renal Cell Carcinoma (RCC)...

Several anatomical magnetic resonance imaging (MRI) markers for Alzheimer's disease (AD) have been identified. Cortical gray matter volume, cortical thickness, and subcortical volume have been used successfully to assist the diagnosis of Alzheimer's disease (AD) including its early warning and developing stages, e.g., mild cognitive impairment (MCI) including MCI converted to AD (MCIc) and MCI not converted to AD (MCInc). Currently, these anatomical MRI measures have mainly been used separately. Thus, the full potential of anatomical MRI scans for AD diagnosis might not yet have been used optimally...

Aspergillosis is a common respiratory fungal disease in African penguins ( Spheniscus demersus ) under managed care, and treatment failures with itraconazole due to drug resistance are increasingly common, leading to recent use of voriconazole. Empirical dosing with voriconazole based on other avian studies has resulted in adverse clinical drug effects in penguins. The objective of this study was to determine oral voriconazole pharmacokinetics (PK) in African penguins (n = 18). Single and once daily multiple oral doses of 5 mg/kg voriconazole were evaluated with a 4-mo washout period between trials...

Apelin is the endogenous ligand for the G protein-coupled receptor APJ, and plays important roles in the cardiovascular system. Our previous studies showed that apelin-13 promotes the hypertrophy of H9c2 rat cardiomyocytes through the PI3K-autophagy pathway. The aim of this study was to explore what roles ER stress and autophagy played in apelin-13-induced hypertrophy of cardiomyocytes in vitro. Treatment of H9c2 cells with apelin-13 (0.001-2 μmol/L) dose-dependently increased the production of ROS and the expression levels of NADPH oxidase 4 (NOX4)...
