Multicenter clinical assessment of improved wearable multimodal convulsive seizure detectors Onorati, F., Regalia, G., Caborni, C., Migliorini, M., Bender, D., et al. (2017), Multicenter clinical assessment of improved wearable multimodal convulsive seizure detectors. Epilepsia. doi:10.1111/epi.13899 Objective New devices are needed for monitoring seizures, especially those associated with sudden unexpected death in epilepsy (SUDEP). They must be unobtrusive and automated, and provide false alarm rates (FARs) bearable in everyday life. This study quantifies the performance of new multimodal wrist-worn convulsive seizure detectors. Methods Hand-annotated video-electroencephalographic seizure events were collected from 69 patients at six clinical sites. Three different wristbands were used…

Short-course treatment for multidrug-resistant tuberculosis: the STREAM trials. Moodley, R., Godec, T. R., & STREAM Trial Team. (2016). Short-course treatment for multidrug-resistant tuberculosis: The STREAM trials. European Respiratory Review : An Official Journal of the European Respiratory Society, 25(139), 29-35. doi:10.1183/16000617.0080-2015 Multidrug-resistant (MDR) tuberculosis (TB) is a threat to global TB control, as suboptimal and poorly tolerated treatment options have resulted in largely unfavourable outcomes for these patients. The last of six cohort studies conducted in Bangladesh which assessed a new shorter regimen using currently available TB drugs showed promising results and offered the possibility of a more acceptable and more effective…

Incidence of Previously Undiagnosed Atrial Fibrillation Using Insertable Cardiac Monitors in a High-Risk Population: The REVEAL AF Study Reiffel JA, Verma A, Kowey PR, al e. Incidence of previously undiagnosed atrial fibrillation using insertable cardiac monitors in a high-risk population: The reveal af study. JAMA Cardiology. 2017. http://dx.doi.org/10.1001/jamacardio.2017.3180. Importance  In approximately 20% of atrial fibrillation (AF)–related ischemic strokes, stroke is the first clinical manifestation of AF. Strategies are needed to identify and therapeutically address previously undetected AF. Objective  To quantify the incidence of AF in patients at high risk for but without previously known AF using an insertable cardiac monitor. Design, Setting, and Participants  This…

Jackie Werner Hot Topics in Research, Oncology, Uncategorized

Nondestructive tissue analysis for ex vivo and in vivo cancer diagnosis using a handheld mass spectrometry system Zhang J, Rector J, Lin JQ, et al. Nondestructive tissue analysis for ex vivo and in vivo cancer diagnosis using a handheld mass spectrometry system. Science Translational Medicine. 2017;9(406). http://dx.doi.org/10.1126/scitranslmed.aan3968 Conventional methods for histopathologic tissue diagnosis are labor- and time-intensive and can delay decision-making during diagnostic and therapeutic procedures. We report the development of an automated and biocompatible handheld mass spectrometry device for rapid and nondestructive diagnosis of human cancer tissues. The device, named MasSpec Pen, enables controlled and automated delivery of a discrete…

Hot Topics: Cardiovascular Event Risk Lowered by Reducing Inflammation Alone

Jackie Werner Cardiology, Hot Topics in Research

Antiinflammatory Therapy with Canakinumab for Atherosclerotic Disease Ridker PM, Everett BM, Thuren T, et al. Antiinflammatory therapy with canakinumab for atherosclerotic disease. N Engl J Med. 2017. http://dx.doi.org/10.1056/NEJMoa1707914. BACKGROUND Experimental and clinical data suggest that reducing inflammation without affecting lipid levels may reduce the risk of cardiovascular disease. Yet, the inflammatory hypothesis of atherothrombosis has remained unproved. METHODS We conducted a randomized, double-blind trial of canakinumab, a therapeutic monoclonal antibody targeting interleukin-1β, involving 10,061 patients with previous myocardial infarction and a high-sensitivity C-reactive protein level of 2 mg or more per liter. The trial compared three doses of canakinumab (50 mg, 150…

Jackie Werner Hot Topics in Research, Oncology

Inhibition of pRB pathway differentially modulates apoptosis in esophageal cancer cells Soletti RC, Biasoli D, Rodrigues NALV, et al. Inhibition of pRB pathway differentially modulates apoptosis in esophageal cancer cells. Translational Oncology. 2017;10(5):726-733. doi: http://dx.doi.org/10.1016/j.tranon.2017.06.008. Esophageal cancer is the sixth most common cause of cancer-related death worldwide. Current chemotherapy regimens include a combination of 5-fluorouracil (5-FU) and cisplatin, but more efficient therapy strategies are needed to increase 5-year survival. Alterations in the signaling pathway of the tumor suppressor gene Rb-1, which encodes a phosphoprotein (pRB) that negatively regulates the G1/S transition of the cell cycle, are present in 70% of all tumors, but…
