Objective
To determine whether stratification of complexity models in congenital heart surgery (RACHS-1, Aristotle basic score and STS-EACTS mortality score) fit to our center and determine the best method of discriminating hospital mortality.Methods
Surgical procedures in congenital heart diseases in patients under 18 years of age were allocated to the categories proposed by the stratification of complexity methods currently available. The outcome hospital mortality was calculated for each category from the three models. Statistical analysis was performed to verify whether the categories presented different mortalities. The discriminatory ability of the models was determined by calculating the area under the ROC curve and a comparison between the curves of the three models was performed.Results
360 patients were allocated according to the three methods. There was a statistically significant difference between the mortality categories: RACHS-1 (1) - 1.3%, (2) - 11.4%, (3)-27.3%, (4) - 50 %, (P<0.001); Aristotle basic score (1) - 1.1%, (2) - 12.2%, (3) - 34%, (4) - 64.7%, (P<0.001); and STS-EACTS mortality score (1) - 5.5 %, (2) - 13.6%, (3) - 18.7%, (4) - 35.8%, (P<0.001). The three models had similar accuracy by calculating the area under the ROC curve: RACHS-1- 0.738; STS-EACTS-0.739; Aristotle- 0.766.Conclusion
The three models of stratification of complexity currently available in the literature are useful with different mortalities between the proposed categories with similar discriminatory capacity for hospital mortality. 相似文献43.

Background :
Immunological and inflammatory mechanisms play a key role in the development and progression of type 2 diabetes mellitus.Aim :
To raise the hypothesis that alterations in immunological parameters occur after duodenojejunal bypass surgery combined with ileal interposition without gastrectomy, and influences the insulin metabolism of betacells.Methods :
Seventeen patients with type 2 diabetes mellitus under clinical management were submitted to surgery and blood samples were collected before and six months after surgery for evaluation of the serum profile of proinflammatory (IFN-γ, TNF-α, IL-17A) and anti-inflammatory cytokines (IL-4, IL-10). In addition, anthropometric measures, glucose levels and insulin use were evaluated in each patient.Results :
No changes in the expression pattern of proinflammatory cytokines were observed before and after surgery. In contrast, there was a significant decrease in IL-10 expression, which coincided with a reduction in the daily insulin dose, glycemic index, and BMI of the patients. Early presentation of food to the ileum may have induced the production of incretins such as GLP-1 and PYY which, together with glycemic control, contributed to weight loss, diabetes remission and the consequent good surgical prognosis of these patients. In addition, the control of metabolic syndrome was responsible for the reduction of IL-10 expression in these patients.Conclusion :
These findings suggest the presence of low-grade inflammation in these patients during the postoperative period, certainly as a result of adequate glycemic control and absence of obesity, contributing to a good outcome of surgery. 相似文献44.

Bibliometry is a quantitative statistical technique to measure levels of
production and dissemination of knowledge, as well as a useful tool to track the
development of an scientific area. The valuation of production required for
recognition of researchers and magazines is accomplished through tools called
bibliometricindexes, divided into quality indicators and scientific impact.
Initially developed for monographs of statistical measures especially in
libraries, today bibliometrics is mainly used to evaluate productivity of
authors and citation repercussion. However, these tools have limitations and
sometimes provoke controversies about indiscriminate application, leading to the
development of newer indexes. It is important to know the most common search
indexes and use it properly even acknowledging its limitations as it has a
direct impact in their daily practice, reputation and funds achievement. 相似文献

The Strongest Correlates of PTSD for Firefighters: Number,Recency, Frequency,or Perceived Threat of Traumatic Events? 下载免费PDF全文

Firefighters experience a wide range of traumatic events while on duty and are at risk to develop psychopathology and posttraumatic stress disorder (PTSD). According to cognitive models, the person's interpretation of the traumatic event is responsible for the development of PTSD rather than the traumatic event itself. This cross‐sectional study aimed to explore the contribution of perceived threat to explain PTSD symptoms in Portuguese firefighters, after adjusting for potential confounding factors. A sample of 397 firefighters completed self‐report measures of exposure to traumatic events, psychopathology, and PTSD. Perceived threat explained unique variance in PTSD symptoms, R2 = .40, ΔR2 = .02, F(10, 367) = 24.55, p < .001, Cohen's f2 =.03, after adjusting for psychopathology, number, recency, and frequency of the events, and other potential confounding variables. The association between psychopathology and PTSD was also moderated by perceived threat, R2 = .43, ΔR2 = .03, F(11, 366) = 25.33, p < .001, Cohen's f2 =.05. Firefighters may benefit from interventions that focus on perceived threat to prevent PTSD symptoms. 相似文献

The Pediatric Dentistry Clinic staff of the Federal University of Santa Catarina (UFSC) treated a 5-year-old patient who had multiple dental treatment necessities. He also had cystic fibrosis (CF). As CF is an incurable disease that affects the mucous glands, especially the ones related to the lungs and digestive organs, the patient presented both chronic respiratory and intestinal problems. Such problems resulted in a severely compromised nutritional status. Patients who have CF may present problems in oral health because they receive food supplementation that is rich in carbohydrates. Behavioral changes of such patients when in contact with health professionals are also a point to consider because these changes may make the treatment difficult. That is the reason why oral complications imposed by the disease, as well as the psychological aspects related to it, need to be discussed so that treatment is given to the patient aiming at physical and emotional comfort. 相似文献

This prospective longitudinal study assessed the 3D soft tissue changes following mandibular advancement surgery. Cranial base registration was performed for superimposition of virtual models built from cone beam computed tomography (CBCT) volumes. Displacements at the soft and hard tissue chin (n = 20), lower incisors and lower lip (n = 21) were computed for presurgery to splint removal (4-6-week surgical outcome), presurgery to 1 year postsurgery (1-year surgical outcome), and splint removal to 1 year postsurgery (postsurgical adaptation). Qualitative evaluations of color maps illustrated the surgical changes and postsurgical adaptations, but only the lower lip showed statistically significant postsurgical adaptations. Soft and hard tissue chin changes were significantly correlated for each of the intervals evaluated: presurgery to splint removal (r = 0.92), presurgery to 1 year postsurgery (r = 0.86), and splint removal to 1 year postsurgery (r = 0.77). A statistically significant correlation between lower incisor and lower lip was found only between presurgery and 1 year postsurgery (r = 0.55). At 1 year after surgery, 31% of the lower lip changes were explained by changes in the lower incisor position while 73% of the soft tissue chin changes were explained by the hard chin. This study suggests that 3D soft tissue response to mandibular advancement surgery is markedly variable. 相似文献
