Tratabilidade de águas pluviais utilizando coagulante natural a base de tanino visando fins não potáveis

This paper aimed to study the treatability of rainwater using natural coagulant tannin based. Assays were performed in laboratory scale and aimed to study the conditions most suitable for dosage and for pH of coagulation. Preliminary tests indicated that tannin concentration of 3% (m/m) prepared from the commercial solution presented the best set of results (84.3% of removal for apparent color and 82.51% for turbidity) compared to ferric chloride (66.25% of removal for apparent color and 67.82% for turbidity) and starch (73.68% of removal for apparent color and 67.19% for turbidity). The coagulation diagrams indicate that the best region for dosage ranges from 15 mg/L to about 37.5 mg/L and for pH ranging from about 6.5 to 7.5. The results indicate that the tannin based natural coagulant may be an alternative to conventional coagulants for rainwater treatment seeking non potable uses.

A prelude to the fractional calculus applied to tumor dynamic

In order to refine the solution given by the classical logistic equation and extend its range of applications in the study of tumor dynamics, we propose and solve a generalization of this equation, using the so-called Fractional Calculus, i.e., we replace the ordinary derivative of order 1, in one version of the usual equation, by a non-integer derivative of order 0 < α < 1, and recover the classical solution as a particular case. Finally, we analyze the applicability of this model to describe the growth of cancer tumors.

Kasabach-Merritt syndrome: clinical vs. surgical treatment

Kassabach-Merritt syndrome is a combination of capillary hemangioma and thrombocytopenia that predisposes to bleeding with petechiae, ecchymosis and spontaneous bruising. Treatment is generally started with corticosteroids, interferon alpha or chemotherapy. We present the case of a child (aged 1 year and 9 months) with a giant hemangioma, from the root of the thigh to the knee, and thrombocytopenia. Treatment was started with corticosteroids, without improvement, and then intra-tumor and cutaneous bleeding appeared spontaneously. The patient’s clinical condition precluded prescription of vincristine and interferon and emergency tumor resection was conducted because of extreme thrombocytopenia and bleeding. The child then began to develop sepsis with hypotension and ischemia of remnant tissues. This case presented a therapeutic challenge, which is the subject of this article.

Endovascular repair of a juxtarenal saccular aneurysm using the Multilayer Flow Modulator: report of the first case performed in a Public Hospital in Brazil

Endovascular aortic aneurysm repair (EVAR) involving renal and visceral arteries remains a great challenge. Several techniques have been developed over the time to treat juxtarenal, pararenal and thoracoabdominal aneurysms, highlighting the fenestrated and branched endografts, parallel prostheses as Chimney, Periscope and Sandwich Techniques and the use of flow modulation by multilayer stent. We report a case of saccular juxtarenal aortic aneurysm with high surgical risk for complex airway access due to a history of radical laryngectomy for laryngeal neoplasm. Due to chronic aorto-iliac obstructive disease, ostial stenosis of renal artery and limited diameter of the suprarenal aorta, we discarded options involving fenestrated/branched endografts and involving parallel prostheses techniques. We present this case as a therapeutic challenge and a successful treatment option in the short-term evaluation.

Unfavorable iliac artery anatomy causing access limitations during endovascular abdominal aortic aneurysm repair: application of the endoconduit technique

Endovascular aneurysm repair (EVAR) is already considered the first choice treatment for abdominal aortic aneurysms (AAA). Several different strategies have been used to address limitations to arterial access caused by unfavorable iliac artery anatomy. The aim of this report is to illustrate the advantages and limitations of each option and present the results of using the internal endoconduit technique and the difficulties involved.

Diagnósticos de enfermagem prevalentes em geriatria segundo o grau de dependência

This is a quantitative study conducted at the Outpatient Clinic of the Geriatrics and Gerontology Academic League of Botucatu School of Medicine. It aimed at learning about the profile of elderly patients and their level of disability in relation to basic activities of daily living. Based on this information, nursing diagnoses for the population under study were made, and the most frequent diagnosed were selected with the purpose of composing a stage of the instrument for nursing consultation in geriatric. It was found that the disabled elderly patients were predominantly females and widowed. They had a mean age of 81 years and had completed the first 4 grades of elementary school. Chronic pain related to physical disability and impaired ambulation related to the presence of osteoarticular diseases are examples of the most common diagnoses in the studied population. It is important that geriatric nurses implement Nursing Care Systematization based on the knowledge of the population to which they attend by considering the level of disability of elderly patients with respect to basic activities of daily living, so that full and individualized care can be provided and the patients’ remaining autonomy can be preserved.

As interfaces da convivência da família em uma unidade de pronto socorro

The aim was to describe the positive and negative aspects in a family communication at an emergency care unit. This is a descriptive research with a qualitative approach. The sample consisted of 20 family members / caregivers of patients admitted to the emergency room of a university hospital. Data collection was carried out through semi-structured interviews applied during the period of May-June 2011. Data analysis was performed using the methodological framework of the Collective Subject Discourse which resulted in four themes: Lack of information compromising the family/health professional ties; The ideal model of information provided by the professional regarding the condition of the hospitalized relative; Assessment of information provided about hospital routines; and The role of the relative/companion. Therefore, for the patient and his family, communication is presented as a tool on the care given with the function of transmitting safety, respect and guidance. However when it is incomplete, it becomes a potential form of stress and dissatisfaction.

Educação continuada e gerência participativa: indicadores de qualidade da gestão de recursos humanos em enfermagem

With the purpose to contribute to the construction of quality indicators in human resources management, this study aimed at identifying, from the perspective of nurse managers, essential elements in the composition of indicators for evaluating human resources management in nursing. To that end, phenomenology was adopted as the theoretical methodological framework for this qualitative investigation, in which ten nurses performing in teaching or care provision at a university hospital participated. Following approval by the Committee of Ethics in Research and the subjects’ consent, interviews were performed from September 2005 to July 2006. The analysis enabled the recovery of the following topics “Professional education”, “Training multiprofessional nursing teams” and “Institutional training conditions” in the Permanent Education category and topics “Actions that favor participant management” and “Team work” in the Participant Management category. In its conclusion, the study considers the findings to allow identify elements constituting quality indicators in human resources management.

Estudo com familiares de pacientes com câncer de mama: abordando conhecimento sobre fatores de risco

Breast cancer (BC) is the most common malignancy in women worldwide, with one million new cases confirmed each year. This study aimed at identifying the knowledge of patients? relatives concerning the risk factors (RF) for BC. It is a descriptive quantitative study carried out in the Chemotherapy Technical Division of a University Hospital in São Paulo state, Brazil, from September to October 2006. Only female (30) relatives were included due to the fact that BC is more frequent in females. The major RF cited were family history for BC 33.3% (10), smoking 16.6% (5), alcoholic-drink consumption 10% (3), animal-fat-rich diet 3.3% (1). Other factors such as not breastfeeding, environmental factors, use of oral contraceptives and hormone-replacement therapy were mentioned by 10% (3) of the relatives. It was concluded that the relatives of patients undergoing chemotherapeutic treatment showed to have little knowledge concerning RF for BC. Hence, it is important to rethink the inclusion of the health education process in the family scenario. This issue reaches far beyond thesimple transmission of information. Healthcare professionals and nurses in particular, must focus on these individuals? social context, values, beliefs and needs.

Sorovacinação antirrabica: aspectos epidemiologicos e implicações para assistência de enfermagem

This study was developed with the purpose to search for relevant knowledge concerning nursing care for individuals exposed to the rabies virus and submitted to post-exposure anti-rabies serovaccination. The authors aimed at evaluating the epidemiological aspects of accidents involving household and wild animals occurring in 2007 and patients assisted at a reference hospital located in the mid-southern region of São Paulo State. They also aimed at identifying the relevance of nurses' actions by describing aspects of care provision. The method adopted was exploratory, retrospective and descriptive of the epidemiological aspects of the accidents and of the care provided to these patients by referring to information in their medical charts. Fifty-one charts of patients aged 17 to 81 years, considered to be at risk and with indication for post-exposure prophylaxis against human rabies were evaluated. It was found that nursing care provision to these patients presents low complexity although it requires properly trained professionals. It was possible to identify the relevance of nurses' actions in care provision and procedures related to anti-rabies prophylaxis; however, consistent information concerning nursing care was not observed.

Enfermagem cuidando de paciente adulto e família no processo de morte em sala de emergência

The purpose of the study was to understand the experience of nursing professionals on the care provided to adult patients and relatives who experience the dying process in an emergency room. Statements of 12 nursing professionals, being 8 technicians and 4 registered nurses of the emergency room of a high-complexity university hospital were analyzed. Data was collected by means of semi-structured interviews and evaluated according to Bardin’s content analysis. As a result, the theme entitled the relative’s mourning process emerged with two categories: alterity as an opening and suffering as a limit. when subjectivity, which was revealed under the principle of alterity, permeated the subjects’ actions, the nursing practices were targeted at the patients and their relative’s needs, but suffering as a limit imposed distancing by the professionals during care provision, even when it was perceived as necessary.

Reproductive physiology, and physical and sexual development of female offspring born to diabetic dams

Objectives: The objective of this study was to evaluate physical and sexual development and reproductive physiology in female rat offspring that developed in hyperglycemia conditions in utero and during lactation. Materials and methods: Maternal diabetes was induced in female rats by a single IV injection of streptozotocin before mating. Female offspring development was evaluated by means of the following parameters: physical development; age of vaginal opening and first estrus; weight and histological evaluation of uterus and ovaries; duration of the estrous cycle, sexual behavior, and fertility after natural mating. Results: In the female offspring, maternal diabetes caused delays in initial physical development; diminution in ovary weight and number of follicles; and inferior reproductive performance compared with the control group. Conclusions: The exposure to hyperglycemia in uterus and during lactation caused delays in physical and sexual development, and affected the reproductive physiology of female rats negatively.
