Evaluation of Business Intelligence Projects Success – a Case Study


Background: Many studies found in literature only focus on specific aspects of the evaluation of the success of projects, such as the criteria for evaluation; and just a few are focused on the activities for evaluating success. Objectives: The goal of the paper is to present the process for evaluating the success of Business Intelligence (BI) projects in a large company. Methods/Approach: An exploratory case study was carried out at Tintas Robbialac, SA, a Portuguese company of the paint industry. Results: The specific company approach for evaluating the success of BI projects is presented and discussed. Conclusions: The process for evaluating the success of BI, as well as the evaluation criteria, should be formally defined; and the success should be evaluated and monitored along all the project lifecycle.

The impact of demographic and clinical characteristics on diabetic painful neuropathy


Introduction: Diabetic neuropathy (DN) is one of the most devastating complications of diabetes mellitus; however, in contrast to other countries, there are no scientific studies in Portugal evaluating the impact of demographic and clinical characteristics of this pathological entity. The aim of this study was to evaluate the impact of gender, metabolic control, age of diabetic patients, as well as time of disease progression, the appearance of complaints related to neuropathic pain.

Material and Methods: A multicentre study with a non-probabilistic, convenience sample of 359 patients was performed employing the quantitative method, using the Statistical Package for Social Science 24 software. The p-value of p<0.05 was defined to consider a result statistically significant. The Spearman correlation coefficient (r) was determined to determine the relationship between categorical variables.

Results: There was no statistically significant difference in the prevalence of DN between genders (p=0.633 and r=0.025). There was a statistically significant relationship between the value of HbA1c and DN, with p=0.010 and r=0.136. There is a relationship between age and complaints of neuropathic pain, with p=0.034 and r=0.112. The variable, time of disease progression, is also correlated with the appearance of complaints of neuropathic pain with p=0.020 and r=0.112.

Conclusion: The prevalence of neuropathic pain in subjects with diabetes is not negligible and is associated with modifiable risk factors that can be identified, possibly modified and prevented. The correct approach for these patients, which involves screening and early treatment, is decisive improving functionality and quality of life.

Celiac Disease and Cystic Fibrosis: Challenges to Differential Diagnosis


Cystic fibrosis and celiac disease were considered a single clinical entity for many years. Differentiation between the diseases occurred some time in the 1930s of the 20th Century. Both diseases may present the intestinal malabsorption syndrome and similar clinical manifestations that contribute to difficulties with clinical distinction. We describe a report of two patients with initial diagnosis of cystic fibrosis, who were subsequently diagnosed with celiac disease.

These case reports emphasize the possibility of false positivity being shown in the sweat test in CD, which may result in delayed diagnosis and inadequate management of this disease.
