A Health- and Resource-Oriented Perspective on NSLBP

Nonspecific low back pain (NSLBP) is an important health issue of our time. Personal as well as economic factors, like suffering pain and experiencing disability on the one hand and enormous and still increasing costs to the economy and society on the other hand, display the importance of the matter. Tremendous research has been conducted in the last few decades on NSLBP. A PubMed search (June 17, 2013) on “low back pain” provided 22,980 hits, and when specifying for “low back pain, systematic review,” 3,134 hits were still generated. Most research has been done examining the development, risk factors, or therapeutic measures of NSLBP, but hardly any literature exists on resources related to NSLBP. The aims of this review are twofold. In order to shade light on the salutogenetic approach of NSLBP, and thus to focus on health instead of illness, the first aim is to facilitate the understanding of which therapeutic measures enhance the ability to cope with chronic NSLBP and enable (more) normal functioning in life. The second aim is to stimulate the understanding of resources protecting against the onset of NSLBP or against the development of chronic NSLBP and its resulting work absence.

La música Latinoamericana en el canon musicológico europeo

Lateinamerikanische Musik spielt im musikhistoriographischen Kanon europäischer Musikwissenschaft kaum eine Rolle, umgekehrt orientieren sind lateinamerikanische Musikwissenschaftler fast obsesiv an europäischen Paradigmen. Dieses Ungleichgewicht fördert gegenseitige Missverständnisse.

Globalized Antiquity: Uses and Perceptions of the Past in South Asia, Mesoamerica, and Europe

„Antike“ ist keine europäische Exklusivität: Das Buch zeigt, wie in Südasien, Mesoamerika und Europa je eigene Antiken konstruiert werden. In den untersuchten vorkolonialen, kolonialen und postkolonialen Zusammenhängen wird die Antike durch die zeitgenössische Geschichtspolitik stark mitbestimmt. Der Vergleich lässt die Verflechtung der Vorstellungen über die Vergangenheit zwischen „klassischer“ europäischer, indischer und mesoamerikanischer Antike von der frühen Neuzeit bis in die Gegenwart erkennen. Das Buch bietet Denkanstöße für Personen, die sich mit historisch interessierter Kulturanthropologie, kritischer Altertumswissenschaft und Globalgeschichte beschäftigen.

Modest Improvement in Overall Survival for Patients With Metastatic Pancreatic Cancer

OBJECTIVES: Patients with pancreatic adenocarcinoma often present with distant metastatic disease. We aimed to assess whether improvements in survival of clinical trials translated to a population-based level. METHODS: The US Surveillance, Epidemiology, and End Results registry was queried. Adult patients with distant metastatic adenocarcinoma of the pancreas were included from 1988 to 2008. Overall survival was analyzed using Kaplan-Meier curves as well as multivariable-adjusted Cox proportional hazards models. RESULTS: In total, 32,452 patients were included. Mean age was 67.6 (SD: 11.7) years, and 15,341 (47.3%) were female. Median overall survival was 3 months (95% confidence interval [CI], 3-3 months), which increased from 2 (CI, 2-2) months in 1988 to 3 (CI, 3-4) months in 2008. After adjustment for multiple covariates, the hazard ratio (HR) decreased by 0.977 per year (CI, 0.975-0.980). In multivariable-adjusted survival analyses, tumor location in the pancreatic body/tail (HR, 1.10), male sex (HR, 1.09), increasing age (HR, 1.016), African American ethnicity (HR, 1.16), nonmarried civil status (HR, 1.18), and absence of radiotherapy (HR, 1.41) were associated with worse survival (P < 0.001 for all predictors). CONCLUSIONS: The improvement in overall survival over the past 2 decades among patients with metastatic pancreatic adenocarcinoma is modest and disappointing. More effective therapeutic strategies for advanced disease are desperately needed.

Psychological adaptation to marital breakup in middle-aged persons: the role of gender and time

Marital breakup is among the most incisive stressors in adult life. While the negative effects of divorce on well-being are well documented in research literature, the large interindividual differences in psychological adaptation to marital dissolution are still not well understood. One major controversially discussed question is, whether marital dissolution represents a temporary crisis or rather a chronic strain. But also with regard of the role of gender results are mixed. The aim of the present study is to investigate the psychological adaptation (depression, perceived stress and life satisfaction) to marital breakup in a sample of 980 middle-aged persons (M = 51.8 years) who were partnered on average 19.4 years. We compared four time groups: one with a separation within the last 12 months (84 women, 36 men), another within the last 13-24 months (75 women, 19 men), a third within 25-60 months (121 women, 49 men), and one with a separation more than 60 months ago (189 women, 144 men). A group of 348 age-matched married people served as control group (189 women, 159 men). Findings from ANOVA with the outcome depression as well as with the outcome perceived stress yielded a significant main effect for both factors (gender and time). The group who had experienced a separation within the last 12 months differed significantly from all other groups (higher depression score and higher perceived stress). No significant main effect for the factor time was found for the outcome life satisfaction. Regarding gender differences, females from all time groups displayed higher depression scores and higher perceived stress but lower life satisfaction than males. These results give important insights into the process of adaptation to marital breakup, which can be used for counselling.

Sampling strategies for capillary isoelectric focusing with electroosmotic zone mobilization assessed by high-resolution dynamic computer simulation

The impact of initial sample distribution on separation and focusing of analytes in a pH 3–11 gradient formed by 101 biprotic carrier ampholytes under concomitant electroosmotic displacement was studied by dynamic high-resolution computer simulation. Data obtained with application of the analytes mixed with the carrier ampholytes (as is customarily done), as a short zone within the initial carrier ampholyte zone, sandwiched between zones of carrier ampholytes, or introduced before or after the initial carrier ampholyte zone were compared. With sampling as a short zone within or adjacent to the carrier ampholytes, separation and focusing of analytes is shown to proceed as a cationic, anionic, or mixed process and separation of the analytes is predicted to be much faster than the separation of the carrier components. Thus, after the initial separation, analytes continue to separate and eventually reach their focusing locations. This is different to the double-peak approach to equilibrium that takes place when analytes and carrier ampholytes are applied as a homogenous mixture. Simulation data reveal that sample application between two zones of carrier ampholytes results in the formation of a pH gradient disturbance as the concentration of the carrier ampholytes within the fluid element initially occupied by the sample will be lower compared to the other parts of the gradient. As a consequence thereof, the properties of this region are sample matrix dependent, the pH gradient is flatter, and the region is likely to represent a conductance gap (hot spot). Simulation data suggest that sample placed at the anodic side or at the anodic end of the initial carrier ampholyte zone are the favorable configurations for capillary isoelectric focusing with electroosmotic zone mobilization.
