Ten-year comparison of pericardial tissue valves versus mechanical prostheses for aortic valve replacement in patients younger than 60 years of age

Aortic valve replacement using a tissue valve is controversial for patients younger than 60 years old. The long-term survival in this age group, the expected event rates during long-term follow-up, and valve-related complications are not clearly determined.

Damage control in severely injured trauma patients - A ten-year experience

This study reviews our 10-year institutional experience with damage control management and investigates risk factors for early mortality.

Ten years of meta-analyses on erythropoiesis-stimulating agents in cancer patients

Since erythropoiesis-stimulating agents (ESAs) were licensed in 1993, more than 70 randomized controlled trials and more than 20 meta-analyses and systematic reviews on their effectiveness were conducted. Here, we present a systematic review on the meta-analyses of trials evaluating ESAs in cancer patients.

Examining five- and ten-year survival in older women with breast cancer using cancer-specific geriatric assessment

To examine five- and ten-year survival based on cancer-specific geriatric assessment (C-SGA) in older women with early stage breast cancer.

Relationship between chronic stress and carotid intima-media thickness (IMT) in elderly Alzheimer's disease caregivers

The stress associated with providing care for a spouse diagnosed with Alzheimer's disease can have adverse effects on cardiovascular health. One potential explanation is that chronic caregiving stress may contribute to the development of atherosclerosis. The purpose of this study was to determine whether the duration that one has provided care is associated with the degree of atherosclerotic burden, as measured by carotid artery intima-media thickness (IMT). One hundred and ten Alzheimer caregivers [mean age 74 ± 8 (SD) years, 69% female] underwent in-home assessment of carotid artery IMT via B-mode ultrasonography. Data regarding medical history, blood pressure, and multiple indicators of caregiving stress were also collected. Multiple regression indicated that duration of care was positively associated with IMT measured in the internal/bifurcation segments of the carotid artery (β = 0.202, p = 0.044) independent of risk factors such as age, gender, body mass index, smoking history, sleep quality, hypertension status, and caregiving stressors. Duration of care was positively associated with IMT in the common carotid artery, but the relationship was not significant. These findings provide more evidence of the link between chronic caregiving stress and cardiovascular disease and indicate that enduring the experience of caregiving over a period of years might be associated with atherosclerotic burden.

Vorsorglicher Rechtsschutz. Vorsorgliche Massnahmen im internationalen Kontext, offene Fragen im neuen Arrestrecht und Sicherungsmassnahmen der ZPO, mit Beiträgen von Dr. Isabelle Chabloz, Dr. Richard Gassmann, PD Dr. Pascal Grolimund, Dr. Jürg Roth, Prof. Dr. Daniel Staehelin

Am 9. September 2011 führte das Institut für Verfahrensrecht und Internationales Privatrecht (CIVPRO) der Universität Bern in bewährter Zusammenarbeit mit der schweizerischen SchKG-Vereinigung die zweite Schweizer Tagung für Internationales Zivilverfahrensrecht durch. Im Mittelpunkt der Tagung standen vorsorgliche Massnahmen im internationalen Kontext vor dem Hintergrund der neuesten Entwicklungen, namentlich (aber nicht nur) des neuen Lugano-Übereinkommens. Der Tagungsband enthält die auf den Vorträgen basierenden, überarbeiteten und erweiterten Beiträge namhafter Autorinnen und Autoren zum vorsorglichen Rechtsschutz im neuen IZPR (Pascal Grolimund). Besondere Aufmerksamkeit gilt dem neuen Arrestrecht sowohl im als auch ausserhalb des Anwendungsbereichs des Lugano-Übereinkommens (Richard Gassmann und Jürg Roth). Ebenso enthält der Band Beiträge zu den Sicherungsmassnahmen in der Realvollstreckung (Daniel Staehelin) sowie zur Anerkennung ausländischer vorsorglicher Massnahmen (Isabelle Chabloz).

High-resolution electrophoretic simulations: performance characteristics of one-dimensional simulators

Three comprehensive one-dimensional simulators were used on the same PC to simulate the dynamics of different electrophoretic configurations, including two migrating hybrid boundaries, an isotachophoretic boundary and the zone electrophoretic separation of ten monovalent anions. Two simulators, SIMUL5 and GENTRANS, use a uniform grid, while SPRESSO uses a dynamic adaptive grid. The simulators differ in the way components are handled. SIMUL5 and SPRESSO feature one equation for all components, whereas GENTRANS is based on the use of separate modules for the different types of monovalent components, a module for multivalent components and a module for proteins. The code for multivalent components is executed more slowly compared to those for monovalent components. Furthermore, with SIMUL5, the computational time interval becomes smaller when it is operated with a reduced calculation space that features moving borders, whereas GENTRANS offers the possibility of using data smoothing (removal of negative concentrations), which can avoid numerical oscillations and speed up a simulation. SPRESSO with its adaptive grid could be employed to simulate the same configurations with smaller numbers of grid points and thus is faster in certain but not all cases. The data reveal that simulations featuring a large number of monovalent components distributed such that a high mesh is required throughout a large proportion of the column are fastest executed with GENTRANS.

HLA-A*3101 and carbamazepine-induced hypersensitivity reactions in Europeans

Carbamazepine causes various forms of hypersensitivity reactions, ranging from maculopapular exanthema to severe blistering reactions. The HLA-B*1502 allele has been shown to be strongly correlated with carbamazepine-induced Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS-TEN) in the Han Chinese and other Asian populations but not in European populations.
