Qualidade de vida medida pelo "WHOQOL-bref": estudo comparativo de pacientes em hemodiálise e pós-transplante renal

Exploratory descriptive study, prospective with quantitative approach, performed in the nefrology outpatient service from the Onofre Lopes University Hospital (HUOL), Natal/RN, aiming to identify aspects that concern Quality of Life (QOL) on transplanted and hemodialysis patients, as measured by WHOQOL-bref and describe the aspects that differentiate QL between the two groups as measured by the same instrument. The population was of 62 renal patients in hemodialysis and 58 transplantd, with data collected from february to march 2006. The instrument used was WHOQOL-bref, translated to and validated for Portuguese by the multicentric group of the World Health Organization (WHO) in Brazil. The results show predominance of the masculine gender both in the post-transplant group (55,17%), as well as in the hemodialysis group (51,61%); the age strip of 28 to 43 prevailed, among which were 53,45% transplanted and 48,99% hemodialysis patients; 79,93% of the hemodialysis patients and 62,07% of the transplanted were provenient from ouside the capital of the state; from the hemodialysis population, 59,68% were married, while among the transplanted 48,28% were single; 58,06% of the hemodialisys patients had 1 to 3 children, while the majority of the transplanted, 44,83%, had no children; regarding scholarity level on both groups, there was a predominance of incomplete fundamental school, representing 62,9% of the hemodialysis patients and 46,6% of the transplanted; regarding work status, 98,39% of those in hemodialysis informed not to be working, and the same applied to the transplanted, with 75,86%; regarding treatment time, most patients of both populations were in the 1- to 4-year interval, of which were 62,9% of the hemodialisys patients and 53,45% of the transplanted. The analysis of WHOQOL-bref reliability through Crobach s Alpha coefficient had a value of 0,8816, demonstrating good internal consistency for the instrument. Regarding description of QOL tests, the average scores of the post-transplant were (Q-1) 18,14 e (Q-2) 18,69, and 12,3 (Q-1) and 11,29 (Q-2) for the group in hemodialisys. Regarding the aspects that differentiate QOL on the two groups observed through average scores from the Domains: Physical, 15,91 for the post-transplant group and 12,71 for the hemodialisys group; Psychological, 16,75 for the post-transplant group and 14,84 for the hemodialisys group; Social Relations, 17,79 on the post-transplant group and 16,58 on the hemodialisys group; Environment, 14,16 on the post-transplant group and 12,38 on the hemodialisys group. On every evaluated item, the post-transplant group achieved higher scores when compared to the hemodialisys group. The diference in QOL for both populations was significant on all items evaluated with a p<0,005

Dermatophytosis: association between ABO blood groups and reactivity to the trichophytin

Os autores investigaram a relação entre dermatofitose e grupo sanguíneo ABO através da tipagem sanguínea, identificação do dermatófito isolado e resposta imune celular específica de 40 indivíduos portadores desta micose. Verificaram que o fungo Trichophyton rubrum foi isolado em 54,5% dos pacientes, sendo mais frequente em indivíduos pertencentes ao grupo sanguíneo A. A resposta imune celular, avaliada através do antígeno tricofitina, foi positiva em 25% dos pacientes estudados; a presença de reações imediatas (30 min) foi verificada em 35%. A distribuição dos grupos sanguíneos entre pacientes com dermatofitose e grupo controle foi a seguinte: 47,5% x 36% grupo A, 40% x 50% grupo O, 12,5% x 11% grupo B. Embora os autores tenham encontrado um número maior de pacientes pertencentes ao grupo sanguíneo A e infectados pelo T. rubrum, não obtiveram evidência estatística de que esses indivíduos sejam mais suscetíveis as dermatofitoses.

Análise bromatológica de carnes antes e após o processamento para obtenção de charque

The process of salting and drying in the sun is used to preserve meat since the beginning of civilization. There is evidence that this preservation technique has arisen in Egypt, between 4,000 and 5,000 years ago. In our country, according to literature, was the first industrial product that gave the appearance of beef jerky, beef being produced, where about 70% to 75% of the muscle is composed of water, where it will be around 45% as a final product, according to the law in his article RIISPOA No. 432 provides that the jerky should contain no more than this amount of moisture in the muscular portion, or more than 15% of total ash with tolerance of up to 5% variation . Besides this parameter, proteins, lipids, ash, and minerals were analyzed in samples before and after the manufacturing process to know the content of these nutrients. Since these are considered important in product quality, thus the concentration in these samples, respectively, in the flesh Front (CD and CHD) before and after the manufacturing process for humidity were respectively 75.28% and 47.38% , the protein was 14.17 and 22.20 g / 100 g sample, 6.360 and 4.251 of lipids g/100g of the sample, and the ashes 0.974 9.144 g/100g sample, minerals like calcium and 4.074 30 , 06 ppm, sódio0, 055 and 5.401 g / L, sodium chloride, 0.139 and 13.74 g / L, potassium 237.5 and 166.8 ppm, 1.721 and 3.295 ppm iron, 0.143 and 0.135 ppm phosphorus, zinc and 4.690 6.905 ppm; magnésio14, 63 e13, 75 ppm manganese .017 e0, 007ppm, copper 0.057 and 0.039 ppm in the case of needle-type meat (CPA and CHPA), 68.04% and 44.17%, protein 13 , 72, and 24.42 g/100g of sample, 1.137 in the ash and 12.68 g / 100g of sample, and the minerals calcium 17.11 and 12.89 ppm; sódio0, 123 and 4.871 g / L, sodium chloride 0.312 and 12.39 g / L, potassium 305.3 and 182.1 ppm; ferro1, 817 and 1.513 ppm, 0.273 and 0.139 ppm phosphorus, zinc 6.305 and 4.783 ppm, 27.95 and 15.85 ppm magnesium, manganese and 0.025 0.011 ppm, 0.057 and 0.143 ppm copper and chromium 0.014 and 0.068 ppm

Effect of thermal cycling on microleakage between hard chairside relines and denture base acrylic resins

Objectives:Microleakage is a pre-stage of debonding between hard chairside relines and denture base acrylic resins. Therefore, it is important to assess them with regard to the longevity of the relined denture. This study investigated the effect of thermal cycling on the microleakage at the interface of three hard chairside reline resins and three denture base resins.Material and methods:Rectangular bars (12 mm x 3 mm x 3 mm) of Lucitone 550, Acron MC and QC 20 were made and relined with Kooliner, Tokuyama Rebase Fast II and Ufi Gel Hard, Lucitone 550, Acron MC and QC 20 resins. Specimens were divided into one control and two test groups (n = 10). In specimens of the control group, the microleakage was performed after the reline procedure. In Test Group 1, the specimens were stored for 24 h in distilled water at room temperature and in Test Group 2; the specimens were thermal cycled from 5 to 55 degrees C for 5000 cycles with a 30-s dwell time. Subsequently, all specimens were immersed in 50% silver nitrate solutions for 24 h. All specimens were sectioned longitudinally into three fractions and the lateral sections were examined (n = 20). Silver nitrate stain penetration was examined under a stereoscopic lens with x30 magnification, and the images were captured. Leica Qwin image analysis software was used to determine microleakage at the interface of the materials. Data were analysed using the Kruskal-Wallis test at a 95% level of significance.Results:For all cycles, there were no statistically significant differences between thermal cycled and non-thermal cycled groups (p > 0.05).Conclusion:It can be concluded that thermal cycling had no effect on the microleakage.

Transporte jejunal eletrogênico da glicose em ratos com deficiência de niacina.

The active electrogenic absorption of glucose was studied in 12 niacin deficient rats using a method for measuring changes in transmural potential difference across jejunal mucosa. The glucose was infused in 6 different concentrations (2.5; 5.0; 10.0; 20.0; 50.0 and 100.0 mM/L) at a constant rate of 1.7 ml per minute. The apparent kinetic parameters (Km and Pdmax) of active electrogenic transport were obtained graphically from curves of glucose transfer potentials. The results were compared with that obtained in a control group. The curve of glucose transfer potential in niacin deficient group was significantly lower than that of the control group. The apparent Km of niacin deficient group was greater than in the control group (16.1 x 12.7 mM/L). Furthermore, the Pdmax of the deficient group was lower than that of the control group (12.5 x 19.4 mV). The results showed that in niacin deficiency occurs a decreasing of the active electrogenic glucose absorption. One of the possible interpretation of the differences in the kinetic characteristics of electrogenic glucose transport would be a depleted energy supplement for the active transport in the enterocyte of the niacin deficient rats.

Capacidade combinatória para frutificação em cultivares de nogueira macadâmia

A 5 × 5 diallel experiment was conducted at Experimental Station of Tietê, SP, aiming to evaluate the combining ability amongst macadamia nut trees (Macadamia integrifolia Maiden & Betche) cultivars IAC Campinas A, IAC 2-23 A, IAC 4-12 B, IAC 4-20 e IAC 5-10. The initial fruit set was evaluated 14 days after manual pollination and showed that every cultivar presented self incompatibility. There were significant general and specific combining ability amongst cultivars and reciprocal effects. The cultivar IAC Campinas A reduced the initial fruit set at all crossing in which was used as female progenitor. The best results for initial fruit set were showed by crossings between following cultivars: IAC 4-20 × IAC Campinas A, IAC 4-12 B × IAC 2-23 A, IAC 4-20 x× IAC 4-12 B, IAC 5-10 × IAC 2-23 A, IAC 5-10 × IAC 4-20, IAC 4-20 × IAC 2-23 A e IAC 5-10 × IAC 4-12 B.

Nonforward parton distributions of the pion within an effective single instanton approximation

We develop a relativistic quark model for pion structure, which incorporates the nontrivial structure of the vacuum of quantum chromodynamics as modelled by instantons. Pions are bound states of quarks and the strong quark-pion vertex is determined from an instanton induced effective Lagrangian. The interaction of the constituents of the pion with the external electromagnetic field is introduced in gauge invariant form. The parameters of the model, i.e., effective instanton radius and constituent quark mass, are obtained from the vacuum expectation values of the lowest dimensional quark and gluon operators and the low-energy observables of the pion. We apply the formalism to the calculation of the pion form factor by means of the isovector nonforward parton distributions and find agreement with the experimental data. © 2000 Elsevier Science B.V.
