The present study aimed to numerically simulate blood flow within central venous catheters of hemodialysis and its thrombogenic potential. Numerical simulation research performed through the dynamic computational program of fluids. A three-dimensional geometry of right and left internal jugular veins were built, taken from the Visible Human Project®. Catheters with obstructed and unobstructed lateral holes were constructed. For the simulation, we considered the duration of the cardiac cycle of 0.8 s with pulsatile cycle of 75 beats per minute. Shear stress, velocity and pressure increased when the catheter was within the vein and when they were obstructed. At the venous orifice of the catheter that was unobstructed, the velocity increased from 0.99 ± 0.02 m s-1 to 1.79 ± 0.009 m s-1 and the pressure from 1487 ± 0.8 Pa to 3215 ± 0.7 Pa. Blood re-circulation areas have created areas of stagnation of blood flow, making it more susceptible to the development of venous thrombi. This study may contribute to the expansion of multiprofessional partnerships between health professionals and Bioengineering fields in order to study health problems that can be verified through advanced technologies. Such technologies, such as simulation programs, detail possible adverse events based on scientific evidences which often occur silently in patients.
本研究旨在数值模拟血液透析中心静脉导管内的血流及其血栓形成潜力。通过流体动力学计算程序进行数值模拟研究。建立了左右颈内静脉的三维几何形状，取自Visible Human Project®。构建具有阻塞和未阻塞侧孔的导管。在模拟中，我们考虑心脏周期的持续时间为0.8 s，脉搏周期为每分钟75次。导管在静脉内和静脉阻塞时，剪应力、速度和压力均增加。在导管静脉口通畅处，流速由0.99±0.02 m s-1增加到1.79±0.009 m s-1，压力由1487±0.8 Pa增加到3215±0.7 Pa。血液再循环区域造成了血液流动停滞的区域，使其更容易形成静脉血栓。本研究可能有助于扩大卫生专业人员与生物工程领域之间的多专业合作伙伴关系，以研究可通过先进技术验证的健康问题。这些技术，如模拟程序，根据科学证据详细说明可能发生在患者身上的不良事件。

High levels of reactive oxygen species can trigger an imbalance in redox status, which generates oxidative damage in macromolecules. The present study aimed to investigate the influence of oral supplementation with benfotiamine on oxidative stress and antioxidant activity in muscle of trained mice. Twenty-five male Balb/c mice were placed in groups. Sta-Sed: standard diet and sedentary (n = 6); Ben-Sed: benfotiamine supplemented and sedentary (n = 6); Sta-Tr: standard diet and trained (n = 6); and Ben-Tr: benfotiamine supplemented and trained (n = 7). Standard diet was AIN-93 growth and supplemented diet was AIN-93 with benfotiamine (500 mg kg-1). Trained mice were submitted to 6-weeks of endurance swimming training. The concentration of thiobarbituric acid reactive substances (TBARS), non-protein thiols, catalase (CAT) and superoxide dismutase activities (SOD) were analyzed in the gastrocnemius muscle. TBARS concentration was lower in the Ben-Tr group than in Ben-Sed and Sta-Tr groups. Thiol levels were higher in the Ben-Sed group than in the non-supplemented groups. CAT activity was more pronounced in both supplemented groups while SOD activity was higher in the Ben-Tr group than in the non-supplemented groups. The results show that benfotiamine supplementation is effective in enhancing antioxidant defenses and reducing oxidative damage in muscle of endurance-trained mouse.

The present study aimed to evaluate the nutritional state and WL of individuals with cancer. Is a longitudinal observational study was performed with patients assisted in the oncological ambulatory. Sample was composed of 402 patients, with an average of 58.46±13.60 years old, 56.5% women and the majority elderly (51.74%). Regarding tumor localization, 12.9% were found in the head and neck, 22.6% in mamas, 10.2% in the lungs, 29.4% in the gastrointestinal tract (GI tract) and 29.4% in other body parts. A gradual fall of nutritional state in relation to BMI was observed, and the patients were advancing to malnutrition. When severe and not severe WL were correlated, a statistical difference was demonstrated regarding age, current and habitual weight, as well as the corresponding BMI (p<0.05). Overweight and obese patients presented a higher severe WL than the other group (p<0.05). However, 67.34% of patients presented WL and a following nutritional state alteration, being cancer in the GI tract with a significant difference, 37.44% (p<0.05) with severe WL (p<0.000). Patients diagnosed with cancer, especially in the GI tract, treated with chemotherapy have higher chances of WL, which trigger a reduction of survival rate, being obesity and age reliable predictors of a consequent severe WL.

Analyze the epidemiological profile of and years of life lost to suicide in Rio Grande do Norte, Brazil, from 2000 to 2015. This is an ecological study in which data on death were sourced from the Mortality Information System. Years of Potential Life Lost were calculated over the historical series. A total of 2,266 deaths by suicide were analyzed, identified during the period, with the most frequent cases being those occurring at home, by hanging, among men, black people, single people and the elderly. More Years of Potential Life Lost were counted in the economically active age group (30-39 years old). Thus, recognizing the epidemiological characteristics of suicide in Rio Grande do Norte may guide more effective actions and strategies targeting risk populations and reinforces the need for further studies focusing on regions with the highest rates in the state. Moreover, mental health care must be adapted to age and gender, besides approaching social support needs and feeling of belonging.

The use of venous catheters for hemodialysis is associated with high rates of morbidity and mortality in patients with chronic renal failure. The implant of the dual lumen catheter (DLC) assists the patient in a worsening situation but commonly the patient remains with the DLC back home and this requires a series of important measures. The use of printed educational materials becomes an important tool to assist this type of care. Thus, the objective was to create and validate an instructive folder for the self-care of the patient using a catheter for hemodialysis. It is a methodological study of creation and evaluation of technology, in three stages. For validation of the content and style the material was submitted to the evaluation by experts in the area. 92.3% of the participants stated that the folder demonstrates clarity in their language, 53.8% of the participants suggested change and addition of information, and the same percentage also states that the instrument is attractive. The main suggestions were to change some term/word used in the folder, suggest changes to the images used, and include some information in the content. It is presumed then that the use of educational materials results in benefits to the patients who will receive the guidelines for self-care. Thus, the importance of nurses to use these resources for chronic renal patient care is emphasized.

This study analyzed the level of state-anxiety of swimming athletes based on sex, category, competitive specialty, competitive level and competitive experience. Participants were 178 male (n = 105) and female (n = 73) swimmers with mean age of 15.51 ± 1.9 years at regional, national and international levels. The Competitive State Anxiety Inventory-2 (CASI-2) was used as instrument. Data analysis was conducted using the independent Student’s t-test, Mann-Whitney, Kruskal-Wallis and Spearman correlation. The results showed higher levels of self-confidence in males (p = 0.02) and higher levels of cognitive anxiety in females (p = 0.019). Among the competitive specialties, there were differences between levels of cognitive anxiety (p = 0.045) and self-confidence (p = 0.041) of swimmers. Differences were also observed in levels of cognitive anxiety (p = 0.049), somatic anxiety (p = 0.001) and self-confidence (p = 0.047) between swimming competition levels. It was concluded that male swimmers are more self-confident and less anxious than female swimmers and there are different levels of self-confidence and types of anxiety for different competitive specialties and ranking of competitions.

Overweight and obesity are responsible for significant costs of the Brazil’s public health system and can modify the self-perception of the body image, attitudes, cognitions and thoughts. This study intends to propose predictive models to evaluate factors related to body image dissatisfaction among university students. Undergraduate students, with a mean age of 22.4 years, were interviewed in Minas Gerais, Brazil, by means of a behavioral questionnaire and evaluated the body image by scale of figures of silhouettes according to the Brazilian biotype. Contingency analysis pointed out dissatisfaction in 67.1% of the students and the time dedicated to sedentary activities presented significant influence on body image. Female undergraduate students from health science courses with recent weight gain tended to wish smaller silhouettes, while male students wished larger body sizes. Multinomial and logistic regression analyses revealed a good predictive power, but the multinomial regression was more advantageous and effective in demonstrating a satisfactory predictive model comprised of a larger number of variables to explain the body image dissatisfaction.

The objective of the study was to analyze the correlation between the mortality rate from cervical cancer with schooling, Gini index and Human Development Index (HDI). This is an epidemiological, retrospective, observational and ecological study carried out in the 161 intermediate regions of urban articulation in Brazil. The study was based on secondary data from DATASUS and the United Nations Development Program. The spatial analysis of mortality versus schooling, Gini index and HDI was performed. Most municipalities in Brazil with high mortality rate are located in the North and Northeast. In addition, it was observed that schooling, Gini index and HDI directly influence the increase or reduction of mortality. Knowing these fragilities and their distribution in Brazil is necessary to solve the problems and improve the indicators such as the mortality rate.

The present study aimed to identify and compare knowledge and practices of early childhood education professionals from three public nursery schools (A, B and C) in the city of Florianópolis/SC relative to prevention, early detection and handling of acute respiratory infections (ARIs) in children aged between zero and six years old. A total of 120 educators answered a questionnaire. The instrument was composed of 15 close- and open-ended questions, five of which were scored. In statistical analyses, the Anova One-Way test revealed no significant differences for knowledge between professionals from the three institutions, with nursery school B having the highest mean score (6.12 ± 0.8), showing fair knowledge about child care. Overall results point to existing gaps concerning the need for guidance on these aspects of a child’s health.
