Efeitos de desastres naturais ao desempenho orçamentário do estado do Pará

Este trabalho avalia os efeitos dos desastres naturais ao desempenho orçamentário do Governo do Estado do Pará no período de 2000 a 2012, através da análise de correlação do número de decretos de Situação de Emergência ou Estado de Calamidade Pública com: a) a eficiência orçamentária de áreas prioritárias à Gestão de Riscos Naturais; e b) o risco fiscal, calculado pela redução das receitas e realocação do total de verbas previstas. Os resultados indicam que, no Estado do Pará, a vulnerabilidade fiscal aos desastres naturais é alta, principalmente nas áreas de Prevenção (Ciência e Tecnologia e Meio Ambiente). As principais alternativas para a redução dos impactos são o fortalecimento das ações de curto-prazo, o estabelecimento de fundos monetários e a melhoria das atividades de Prevenção.

Cardiovascular risk and mortality in end-stage renal disease patients undergoing dialysis: sleep study, pulmonary function, respiratory mechanics, upper airway collapsibility, autonomic nervous activity, depression, anxiety, stress and quality of life: a prospective, double blind, randomized controlled clinical trial

Background: Chronic kidney disease (CKD) is one of the most serious public health problems. The increasing prevalence of CKD in developed and developing countries has led to a global epidemic. The hypothesis proposed is that patients undergoing dialysis would experience a marked negative influence on physiological variables of sleep and autonomic nervous system activity, compromising quality of life.Methods/Design: A prospective, consecutive, double blind, randomized controlled clinical trial is proposed to address the effect of dialysis on sleep, pulmonary function, respiratory mechanics, upper airway collapsibility, autonomic nervous activity, depression, anxiety, stress and quality of life in patients with CKD. The measurement protocol will include body weight (kg); height (cm); body mass index calculated as weight/height(2); circumferences (cm) of the neck, waist, and hip; heart and respiratory rates; blood pressures; Mallampati index; tonsil index; heart rate variability; maximum ventilatory pressures; negative expiratory pressure test, and polysomnography (sleep study), as well as the administration of specific questionnaires addressing sleep apnea, excessive daytime sleepiness, depression, anxiety, stress, and quality of life.Discussion: CKD is a major public health problem worldwide, and its incidence has increased in part by the increased life expectancy and increasing number of cases of diabetes mellitus and hypertension. Sleep disorders are common in patients with renal insufficiency. Our hypothesis is that the weather weight gain due to volume overload observed during interdialytic period will influence the degree of collapsibility of the upper airway due to narrowing and predispose to upper airway occlusion during sleep, and to investigate the negative influences of haemodialysis in the physiological variables of sleep, and autonomic nervous system, and respiratory mechanics and thereby compromise the quality of life of patients.

A new tuning fork with different vibration frequencies as an aid to bronchopulmonary hygiene physiotherapy

Background: The main function of the mucociliary system is the removal of particles or substances that are potentially harmful to the respiratory tract. The tuning fork therapeutic for the purpose of bronchial hygiene has still not been described in the literature. The optimal vibration frequency to mobilize secretions is widely debated and varies between 3 and 25 Hz. It is expected that a tuning fork is able to generate vibrations in the thorax, facilitating bronchial hygiene. The aim of the present study is to develop tuning forks with different frequencies, for use in bronchopulmonary hygiene therapy. Methods: The first tuning fork was made with a fixed frequency of 25 Hz and it was recorded in the Brazilian institution of patent registration. This device generated a frequency of 25 Hz and had a weight of 521 g, with dimensions of 600 mm in total length. The device is characterized by a bottom end containing a transducer with a diameter of 62 mm and a thickness of 5/16 mm (8''), a rod removable 148 mm, fork length of 362 mm and an extension at the upper end of sinuous shape bilaterally.The tuning forks must be applied at an angle of 90° directly on the chest wall of the patient after pulmonary auscultation for location of secretions. The tuning fork is activated by squeezing the tips of the extensions together and releasing them in a sudden movement. Results: This study shows the result of the development of others three tuning forks of different dimensions to generate different frequencies. Each equipment reaches a fixed frequency preset of 12, 15 and 20 Hz measured by digital oscilloscope. Conclusions: The tuning fork models developed in this study generated different frequencies proposed by the scientific literature as effective in the mobilization of pulmonary secretions.

Efeito de hipercabia no desenvolvimento de ovos de Trachemys scripta

Females of the painted turtle, Trachemys scripta, have an annual reproductive cycle. Their nest periods in Brazil starts around September and they lay about 7 - 10 eggs in nests dug in the soil. The eggs hatch in December. It is possible that the nest cover cause problems for the gas diffusion, also, the rain can wet or compact the soil covering the nest, or even soaked the whole area. Those problems may change the nests intern atmosphere decreasing O2 partial pressure (hypoxia) and increasing CO2 partial pressure (hypercarbia). The main objective of this study was to determine if and how hypercarbia (3% and 6%CO2), could influence the eggs and early posthatching development of the Trachemys scripta. We used three experimental groups of eggs incubated in: normal atmosphere (Control group CG, n = 14), hypercarbia with 3% of CO2 (G3%, n = 16) and with 6% of CO2 (G6%, n = 15). The profile of the mass increment during the egg development were not different among the groups, GC = 9.89±0.81g; G3% = 10.11±0.60g and G6% = 10.58±0.36g. In addition, the mass of the post-hatching turtles were the not different. There were not differences between the duration of the incubation period among the experimental groups, GC = 60.12±0.97days, G3% = 59.00±0.98days and G6% = 60.80±1.14days. The mortality rates were not affected by the hypercarbia, GC = 0.43 (43%), G3% = 0.27 (27%) and G6% = 0.37 (37%). Furthermore, the mass increment and the metabolic rate were the same among the early development of the turtles until 3 month after hatching. We conclude that hypercarbia (up to 6% of CO2) does not cause any alteration on the eggs or post-hatching normal development. It is possible that the combination of hypercarbia and hypoxia change those results

Busca de atividade leishmanicida de extrato, frações e subfrações obtidas da planta Baccharis trimera (Less.) DC

Segundo a Organização Mundial da Saúde (OMS), leishmanioses são antropozoonoses e estão entre as seis doenças tropicais de maior importância no Velho Mundo e nas Américas. São endêmicas em 88 países e estima-se que sua prevalência seja de 12 milhões de casos no mundo. Nas duas últimas décadas, o número de casos tem aumentado, assim como sua ocorrência geográfica. No Brasil, é uma realidade em diversos estados, apresentando perfis epidemiológicos diferentes. A terapêutica empregada atualmente conta com poucos fármacos, em uso há mais de 40 anos, e que apresentam potencial nefro, hepato e cardiotóxico. Além disto, são contraindicados a idosos e gestantes, o que caracteriza mais um entrave à terapêutica atual. Tendo em vista a imensa biodiversidade brasileira, uma fonte alternativa para o tratamento destas e outras inúmeras enfermidades é a busca de novas moléculas por meio da pesquisa com extratos vegetais e seu fracionamento, a partir de diferentes espécies de plantas. Este trabalho avaliou a atividade leishmanicida do extrato acetato de etila, frações e subfrações obtidas da planta Baccharis trimera (Less.) DC sobre a espécie Leishmania amazonensis. Os ensaios biológicos foram realizados in vitro pelo método colorimétrico de MTT (Brometo de 3-(4,5-dimetiltiazol-2-il)-2,5-difenil-tetrazólio) utilizando formas promastigotas do parasito e macrófagos da linhagem J774, para estudos de citotoxicidade. Os testes foram realizados em triplicata, utilizando-se microplacas de 96 orifícios. Como resultado, três frações (CI50 = 23,56 μg/mL; 29,89 μg/mL; 42,31 μg/mL) e cinco subfrações (CI50 < 1,56 e CI50 = 5, 07 μg/mL ; 5,21 μg/mL; 24,61 μg/mL) apresentaram interessante potencial leishmanicida, sendo que duas destas subfrações também demonstraram baixa citotoxicidade (IS = 64,1). A partir de análises cromatográficas das frações e subfrações... (Resumo completo, clicar acesso eletrônico abaixo)

Trocas simbólicas entre gerações: avós, netos e a literatura infantil

This work aims at understanding the intergenerational relationships between grandparents and grandchildren in contemporary society. To this end, we analyze two works of Children's Literature as a form of manifestation of the importance of symbolic exchanges between generations. Selected Menina Nina: duas razões para não chorar, Ziraldo (2002) and A menina, o cofrinho e a vovó by Cora Coralina (2009). We adopt a psychoanalytic reading as a reference for analysis, since it excels in psychic construction of the individual, his unconscious design and its interaction with the socio-cultural environment , which allows to explore and reflect on the links between generations , thus serving as a research method and interpretation of relationships within the family . We confirm our hypothesis with writers - grandparents, here represented by Ziraldo and Cora Coralina, which produced works that highlight the experience with their grandchildren. Thus, grandparents, grandchildren and readers are active in recovery and symbolic transmission characters.
