The social representation of digital transformation: The IT professionals' perspective.

In this study, we aimed to identify how Information Technology professionals make sense of digital transformation, in order to compare this perception with the scientific literature on the topic. To conduct the research, we adopted the Social Representation Theory. Thus, via an online tool, we applied the words evocation technique as well as an ancillary questionnaire comprising open and closed questions. The expressions collected were then semantically treated and categorized, being then analyzed vis-à-vis their frequency of evocation, relevance, connectedness, and cooccurrence. Then, we performed similarity and content analyses for the open answers received. In doing so, we detected dissonance between scientific production on the concept of digital transformation and the perception of Information Technology professionals on this construct, concluding that such professionals have a technocentric view of digital transformation, based mainly on its technological aspects, which can prevent digital transformation initiatives from fully achieving the desired objectives.

Predictors of Acute Postsurgical Pain After Inguinal Hernioplasty.

Acute postsurgical pain (APSP) is a common and anticipated problem after surgery with detrimental consequences if not appropriately managed. This study examined the independent and joint contribution of presurgical demographic, clinical, and psychological variables as predictors of APSP intensity, evaluated using an 11-point numeric rating scale, after inguinal hernioplasty, one of the most performed surgeries worldwide. In a prospective observational cohort study, a consecutive sample of 135 men undergoing hernioplasty was assessed before and 48 hours after surgery. When adjusted for depression, helplessness, and magnification scores, a multiple hierarchical regression analysis revealed that younger age (ß = -.247, P < .005), previous chronic pain (ß = .175, P < .05), presurgical anxiety (ß = .235, P < .05), and the rumination component of pain catastrophizing (ß = .222, P < .05) were significant predictors of APSP intensity. The integrative predictive model found in this study revealed the simultaneous influence that demographic, clinical, and psychological factors have on APSP after inguinal hernioplasty. Therefore, these results improve knowledge on APSP predictors after inguinal hernioplasty and highlight potential modifiable intervention targets, such as anxiety and pain catastrophizing (rumination), for the design of interventions focused on APSP prevention and management. Hence, taken together, these findings lend support for the inclusion of presurgical screening and psychological interventions among surgical patients at risk for higher APSP intensity. PERSPECTIVE: This study found that, when adjusted for depression, helplessness, and magnification scores, the variables younger age, previous chronic pain, presurgical anxiety, and the rumination component of pain catastrophizing are significant predictors of APSP intensity after inguinal hernioplasty. These findings improve knowledge on APSP and highlight potential modifiable intervention targets for the design of interventions focused on APSP prevention and management.

The selective COX-2 inhibitor Etoricoxib reduces acute inflammatory markers in a model of neurogenic laryngitis but loses its efficacy with prolonged treatment.

OBJECTIVE: A randomised experimental study was used to evaluate the therapeutic effect of a selective cyclooxygenase-2 (COX-2) inhibitor in neurogenic laryngitis. MATERIALS AND METHODS: Male Wistar Han rats were subjected to the nasogastric intubation model (NGI) of laryngitis for 1 and 2 weeks. The NGI animals were divided into three groups: (1) treated with COX-2 inhibitor Etoricoxib, (2) vehicle and (3) non-intubated animals. A fourth group of animals was submitted to NGI only. Laryngeal sections were immunostained for substance P (SP) and calcitonin gene-related peptide (CGRP) fibre-immunoreactivity (IR) and quantification of COX-2 positive cells through stereological analysis. The expression of COX-2, interleukins IL-1beta, IL-6, IL-10 and tumour necrosis factor-alpha (TNF-alpha) was determined by quantitative real time QRT-PCR. TREATMENT: Etoricoxib (6 mg/kg/day) was prepared in 0.9% sterile saline with 5% glucose (vehicle) and administered daily during 1 or 2 weeks. RESULTS: Treatment for 1 week with Etoricoxib attenuated the CGRP-IR fibre depletion, the COX-2-IR increased cell number and the TNF-alpha and COX-2 mRNA increased levels induced by NGI. Two weeks of treatment had no beneficial effect. CONCLUSIONS: Etoricoxib is effective in neurogenic laryngitis for limited periods of administration, indicating that selective COX-2 inhibitors should be evaluated in the future.
