Use of Induced Pluripotent Stem Cells To Recapitulate Pulmonary Alveolar Proteinosis Pathogenesis.
In patients with pulmonary alveolar proteinosis (PAP) syndrome, disruption of granulocyte/macrophage colony-stimulating factor (GM-CSF) signaling is associated with pathogenic surfactant accumulation from impaired clearance in alveolar macrophages. ⋯ We used patient-specific iPS cells to accurately reproduce the molecular and cellular defects of alveolar macrophages that drive the pathogenesis of PAP in more than 90% of patients. These results demonstrate the critical role of GM-CSF signaling in surfactant homeostasis and PAP pathogenesis in humans and have therapeutic implications for hPAP.

Organ failure in the heart or kidney can initiate various complex metabolic, cell-mediated and humoral pathways affecting distant organs, contributing to the high therapeutic costs and significantly higher morbidity and mortality. The universal outreach of cells in an injured state has myriad consequences to distant organ cells and their milieu. Heart performance and kidney function are closely interconnected and communication between these organs occurs through a variety of bidirectional pathways. ⋯ Clinical evidence suggests that tissue injury in both acute kidney injury and heart failure has immune-mediated inflammatory consequences that can initiate remote organ dysfunction. Acute cardiorenal syndrome (CRS type 1) and acute renocardiac syndrome (CRS type 3) are particularly relevant in high-acuity medical units. This review briefly summarizes relevant research and focuses on the role of signaling in heart-kidney crosstalk in the critical care setting.

How do physicians in the specialty of anesthesiology perceive the working conditions regarding stress and job satisfaction? The health system in Germany has been confronted with a rapidly changing framework over the last 20 years: For example, an increased influence of economic patterns on the workflow and the medical decision of physicians has been established forcing them to always take the economic aspects into account. Moreover, a new generation (generation Y) of physicians with other requirements of the work place, meaning mainly a demand for a better work-life balance, has gained a foothold in hospitals. These changes make it very important to investigate the status quo of current working conditions. ⋯ This study revealed a high prevalence of unfavorable working conditions for anesthetists in hospitals. Taking the forthcoming shortage of qualified physicians in German hospitals into account, these results have to be considered as a cause for concern. Constant unfavorable working conditions have a negative effect on the mental and physical health of employees. Sooner or later a migration of qualified physicians abroad could be the consequence. To prevent a future shortage of qualified physicians and to make the hospital work place more appealing, working conditions have to be adapted to current needs and expectations of employees. The focus should be put on balanced working conditions according to stress models shown in this study.

Randomized Controlled Trial
Therapeutic effect of inhaled budesonide (Pulmicort(®) Turbuhaler) on the inflammatory response to one-lung ventilation.
Pre-operative nebulised budenoside may improve ventilation pressures and compliance, and reduce the inflammatory response to one-lung ventilation.

Case ReportsAn Epidural Blood Patch Causing Acute Neurologic Dysfunction Necessitating a Decompressive Laminectomy.
One risk with placement of an epidural blood patch (EDBP) is spinal cord or nerve root compression resulting from the epidural blood volume injected, a complication necessitating immediate surgical decompression. We could not find a previous report of this in the literature. Here, we review and discuss one such case. ⋯ A cauda equina syndrome from an epidural hematoma may occur as a rare complication of an EDBP, even with direct fluoroscopic guidance. Early diagnosis of symptoms and prompt surgical evacuation of an epidural hematoma is essential and may result in the resolution of symptoms. This complication remains a rare occurrence and should not deter the performance of an EDBP, when indicated.
