- Background and purpose The detection of memory impairment is an important part of dementia screening. However, the scope of memory measures in current screening batteries is limited. There is a need for a short yet sensitive instrument for early detection of memory impairment that could serve as a complement to existing globally oriented screening tests, for example, Mini-Mental State Examination (MMSE). To that end, the current study investigates the sensitivity and psychometric properties of the memory screening instrument The Five-Items Memory Screen -Extended Variant (FIMS-XV). Methods Hundred and forty-five participants included in the Gothenburg Mild Cognitive Impairment Study-27 patients with subjective cognitive impairment (SCI), 73 with mild cognitive impairment (MCI), and 45 with mild dementia-underwent cognitive screening including the MMSE and FIMS-XV. Ninety participants also underwent extensive neuropsychological testing. Results The FIMS-XV showed high internal consistency and strong correlations with established neuropsychological memory tests. Both the FIMS-XVdelayed recall score and the FIMS-XV total score differentiated mild dementia patients from patients with SCI and MCI. Conclusions The FIMS-XV shows promise as a sensitive tool for screening for memory impairment in all putative phases of dementia.

Search Heuristics and Market Entry: The Impact of Policy Availability on Novel Market Entry
-
Konferensbidrag (refereegranskat)abstract
- Whereas prior research highlights that firms rely on competitors’ actions and market resource munificence in market entry decisions, the effect of policy availability remains overlooked. In this study, we explore the direct and indirect effects of policy availability on the likelihood of novel market entry. Grounded in the behavioral theory of the firm, we hypothesize that policy availability in a novel market: (1) increases the firm’s likelihood of entry into this market and (2) positively moderates the inverted U-shaped relationship between the number of competitors active in this market and the likelihood of entry into it. Analyzing rich data on the market entry activities of 134 wind turbine manufacturers over a 25- year time period, we largely find empirical support for our predictions. Our study offers new theoretical insights about how search heuristics, and policy availability in particular, influence market entry decisions."

- Cardiovascular (CV) disease and osteoporosis (OP) have been associated with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Bone and vascular biomarkers and parameters along with the effect of 1-year anti-TNF therapy on these markers were assessed in order to determine correlations between vascular pathophysiology and bone metabolism in RA and AS. Thirty-six patients treated with etanercept or certolizumab pegol and 17 AS patients treated with ETN were included in a 12-month follow-up study. Bone and vascular markers were previously assessed by ELISA. Bone density was measured by DXA and quantitative CT (QCT). Flow-mediated vasodilation (FMD), common carotid intima-media thickness (IMT) and pulse-wave velocity (PWV) were assessed by ultrasound. Multiple correlation analyses indicated associations between bone and vascular markers. Osteoprotegerin, sclerostin and cathepsin K were significantly associated with FMD, IMT and PWV, respectively (p < 0.05). Moreover, total and trabecular BMD determined by QCT inversely correlated with IMT (p < 0.05). On the other hand, among vascular parameters, platelet-derived growth factor BB and IMT correlated with DXA femoral and QCT total BMD, respectively (p < 0.05). In the RM-ANOVA analysis, anti-TNF treatment together with baseline osteocalcin, procollagen 1 N-terminal propeptide (P1NP) or vitamin D3 levels determined one-year changes in IMT (p < 0.05). In the MANOVA analysis, baseline disease activity indices (DAS28, BASDAI), the one-year changes in these indices, as well as CRP exerted effects on multiple correlations between bone and vascular markers (p < 0.05). As the pattern of interactions between bone and vascular biomarkers differed between baseline and after 12 months, anti-TNF therapy influenced these associations. We found a great number of correlations in our RA and AS patients undergoing anti-TNF therapy. Some of the bone markers have been associated with vascular pathophysiology, while some vascular markers correlated with bone status. In arthritis, systemic inflammation and disease activity may drive both vascular and bone disease.
