The Asthma-COPD Overlap Syndrome

Abstract: Although in textbooks asthma and chronic obstructive pulmonary disease (COPD) are viewed as distinct disorders, there is increasing awareness that many patients have features of both. This article reviews the asthma-COPD overlap syndrome.

Intramural Hemorrhage of the Thoracic Aorta Diagnostic and Therapeutic Implications

Abstract: Background Intramural hemorrhage (IMH) was recently identified at necropsy and anecdotally in vivo as a unique aortic syndrome (without entry and with no flap-like intraluminal component, such as overt aortic dissection). However, little is known about diagnosis, prognosis, and outcome of IMH. Methods and Results Between 1983 and 1993, 360 patients from two medical centers with clinical indications of aortic dissection were prospectively evaluated; they presented to the emergency department a median of 3.5 hours after onset of back or chest pain or other suggestive symptoms. Among 195 patients with aortic syndromes, 25 patients (12.8%) were diagnosed to have IMH of the thoracic aorta with no evidence of a primary intimal tear, flap, or overt dissection by multiple noninvasive imaging modalities, including magnetic resonance imaging (n=12), contrast-enhanced computed tomography (n=14), and transesophageal echocardiography (n=3) in random order. There were 16 men and 9 women with a median age of 56±13 years...

Decomposition of skin conductance data by means of nonnegative deconvolution

Abstract: Skin conductance (SC) data are usually characterized by a sequence of overlapping phasic skin conductance responses (SCRs) overlying a tonic component. The variability of SCR shapes hereby complicates the proper decomposition of SC data. A method is proposed for full decomposition of SC data into tonic and phasic components. A two-compartment diffusion model was found to adequately describe a standard SCR shape based on the process of sweat diffusion. Nonnegative deconvolution is used to decompose SC data into discrete compact responses and at the same time assess deviations from the standard SCR shape, which could be ascribed to the additional process of pore opening. Based on the result of single non-overlapped SCRs, response parameters can be estimated precisely as shown in a paradigm with varying inter-stimulus intervals.

Measurements of Energetic Particle Radiation in Transit to Mars on the Mars Science Laboratory

Abstract: The Mars Science Laboratory spacecraft, containing the Curiosity rover, was launched to Mars on 26 November 2011, and for most of the 253-day, 560-million-kilometer cruise to Mars, the Radiation Assessment Detector made detailed measurements of the energetic particle radiation environment inside the spacecraft. These data provide insights into the radiation hazards that would be associated with a human mission to Mars. We report measurements of the radiation dose, dose equivalent, and linear energy transfer spectra. The dose equivalent for even the shortest round-trip with current propulsion systems and comparable shielding is found to be 0.66 ± 0.12 sievert.
