Deriving use case diagrams from business process models

In this paper we introduce a technique to simplify requirements capture. The technique can be used to derive functional requirements, specified in the form of UML use case diagrams, from existing business process models. Because use case diagrams have to be constructed by performing interviews, and business process models usually are available in a company, use case diagrams can be produced more quickly when derived from business proces models. The use case diagrams that result from applying the technique, specify a software system that provides automated support for the original business processes. We also show how the technique was successfully evaluated in practice

Moderate alcohol consumption, adiponectin, inflammation and type 2 diabetes risk : prospective cohort studies and randomized crossover trials

Background: Moderate alcohol consumption has been associated with a lower risk of type 2 diabetes in various populations. However, the underlying mechanisms are not entirely clear. The aims of this thesis were 1) to substantiate the evidence of the association between alcohol consumption and type 2 diabetes in observational research and 2) to examine physiological mechanisms in randomized trials with specific attention to adiponectin, inflammation and insulin sensitivity which may mediate the association between alcohol consumption and type 2 diabetes. Methods: Two prospective cohort studies, one among 38,031 U.S. men (age: 45-75 y) of the Health Professionals Follow up Study (HPFS) and one among 35,625 Dutch men and women (age: 20-70 y) of the European Prospective Investigation into Cancer and Nutrition (EPIC)-NL cohort. Four randomized, crossover trials of eight to twelve weeks with consumption of 25-30 g alcohol/day in the form of vodka with orange juice, beer, or white wine (twice) compared to orange juice, alcohol free beer, white grape juice or water among 24 young men, 24 premenopausal and 36 and 22 postmenopausal women, respectively. Results: A 7.5 g/day increase in alcohol consumption over four years was associated with lower diabetes risk among initial non-drinkers (hazard ratio [HR]: 0.78; 95% confidence interval (CI): 0.60, 1.00) and drinkers initially consuming In the randomized crossover trials, alcohol consumption consistently increased circulating adiponectin levels by about 10% compared to abstention (P Conclusions: Moderate alcohol consumption was associated with a lower risk of type 2 diabetes compared with abstention. The association persisted among subjects already at low risk based on combined favorable lifestyle behaviors. Also, increases in alcohol consumption among initially rare and light drinking men were associated with higher adiponectin levels and lower risk of type 2 diabetes. Increased adiponectin levels, anti-inflammatory effects and decreased insulin and triglyceride levels, may partially explain the inverse association between moderate alcohol consumption and type 2 diabetes. <br/

Plasma anandamide and other N-acylethanolamines are correlated with their corresponding free fatty acid levels under both fasting and non-fasting conditions in women

N-acylethanolamines (NAEs), such as anandamide (AEA), are a group of endogenous lipids derived from a fatty acid linked to ethanolamine and have a wide range of biological activities, including regulation of metabolism and food intake. We hypothesized that i) NAE plasma levels are associated with levels of total free fatty acids (FFAs) and their precursor fatty acid in fasting and non-fasting conditions and ii) moderate alcohol consumption alters non-fasting NAE levels. In a fasting and non-fasting study we sampled blood for measurements of specific NAEs and FFAs. In the fasting study blood was drawn after an overnight fast in 22 postmenopausal women. In the non-fasting study blood was sampled before and frequently after a standardized lunch with beer or alcohol-free beer in 19 premenopausal women. Fasting AEA levels correlated with total FFAs (r = 0.84; p <0.001) and arachidonic acid levels (r = 0.42; p <0.05). Similar results were observed for other NAEs with both total FFAs and their corresponding fatty acid precursors. In addition, AEA (r = 0.66; p <0.01) and OEA levels (r = 0.49;

Moderate alcohol consumption alters both leucocyte gene expression profiles and circulating proteins related to immune response and lipid metabolism in men

Moderate alcohol consumption has various effects on immune and inflammatory processes, which could accumulatively modulate chronic disease risk. So far, no comprehensive, integrative profiling has been performed to investigate the effects of longer-term alcohol consumption. Therefore, we studied the effects of alcohol consumption on gene expression patterns using large-scale profiling of whole-genome transcriptomics in blood cells and on a number of proteins in blood. In a randomised, open-label, cross-over trial, twenty-four young, normal-weight men consumed 100 ml vodka (30 g alcohol) with 200 ml orange juice or only orange juice daily during dinner for 4 weeks. After each period, blood was sampled for measuring gene expression and selected proteins. Pathway analysis of 345 down-regulated and 455 up-regulated genes revealed effects of alcohol consumption on various signalling responses, immune processes and lipid metabolism. Among the signalling processes, the most prominently changed was glucocorticoid receptor signalling. A network on immune response showed a down-regulated NF-¿B gene expression together with increased plasma adiponectin and decreased pro-inflammatory IL-1 receptor antagonist and IL-18, and acute-phase proteins ferritin and a1-antitrypsin concentrations (all P <0·05) after alcohol consumption. Furthermore, a network of gene expression changes related to lipid metabolism was observed, with a central role for PPARa which was supported by increased HDL-cholesterol and several apo concentrations (all P <0·05) after alcohol consumption. In conclusion, an integrated approach of profiling both genes and proteins in blood showed that 4 weeks of moderate alcohol consumption altered immune responses and lipid metabolis

Mass Spectrometry for Identification, Monitoring, and Minimal Residual Disease Detection of M-Proteins

BACKGROUND: Monoclonal gammopathies (MGs) are plasma cell disorders defined by the clonal expansion of plasma cells, resulting in the characteristic excretion of a monoclonal immunoglobulin (M-protein). M-protein detection and quantification are integral parts of the diagnosi

Psychosocial functioning of adult siblings of Dutch very long-term survivors of childhood cancer: DCCSS-LATER 2 psycho-oncology study

ObjectiveTo describe psychosocial outcomes among adult siblings of very long-term childhood cancer survivors (CCS), to compare these outcomes to reference populations and to identify factors associated with siblings' psychosocial outcomes. MethodsSiblings of survivors (diagnosed 5 years since diagnosis) of the Dutch Childhood Cancer Survivor Study DCCSS-LATER cohort were invited to complete questionnaires on HRQoL (TNO-AZL Questionnaire for Adult's HRQoL), anxiety/depression (Hospital Anxiety and Depression Scale), post-traumatic stress (Self-Rating Scale for Post-traumatic Stress Disorder), self-esteem (Rosenberg Self-Esteem Scale) and benefit and burden (Benefit and Burden Scale for Children). Outcomes were compared to a reference group if available, using Mann-Whitney U and chi-Square tests. Associations of siblings' sociodemographic and CCS' cancer-related characteristics with the outcomes were assessed with mixed model analysis. ResultsFive hundred five siblings (response rate 34%, 64% female, mean age 37.5, mean time since diagnosis 29.5) of 412 CCS participated. Siblings had comparable HRQoL, anxiety and self-esteem to references with no or small differences (r = 0.08-0.15, p < 0.05) and less depression. Proportions of symptomatic PTSD were very small (0.4%-0.6%). Effect sizes of associations of siblings' sociodemographic and CCS cancer-related characteristics were mostly small to medium (& beta; = 0.19-0.67, p < 0.05) and no clear trend was found in the studied associated factors for worse outcomes. ConclusionsOn the very long-term, siblings do not have impaired psychosocial functioning compared to references. Cancer-related factors seem not to impact siblings' psychosocial functioning. Early support and education remain essential to prevent long-term consequences.Metabolic health: pathophysiological trajectories and therap
