Autoestima e qualidade de vida de pessoas com úlcera venosa atendidas na atenção primária

Venous ulcers (VU) is a chronic injury of the lower extremities and because of its high incidence and recurrence implies long and complex treatments, damaging the quality of life (QOL) and self-esteem (SE) of the people. This study aimed to analyze the association between self-esteem with the quality of life of people with venous ulcers treated in primary care. Cross sectional analytical study with a quantitative approach conducted with 44 people met with VU at 13 primary care units 2 and Mixed units in Natal/RN. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte (UFRN), CAAE: 07556312.0.0000.5537. Held data collection from February to April 2014 and used three instruments: a structured form covering sociodemographic, health care and clinical variables, the Rosenberg Self-Esteem Scale and the SF-36. The collected data were entered into a database and processed on computerized software for descriptive and inferential analyzes. The results showed a predominance of people with UV females (65,9%), with more than 60 years (59,1%), married or in a stable relationship (52,3%), low education (86,4%) without occupation (68,2%) and less than one minimum wage income (81,8%). Regarding assistance characteristics was observed that most patients performed the dressing with appropriate material (72,7%), professional or trained caregiver (61,4%) did not use compression therapy (81,8%), treating the injury for more than 6 months (77,3%), lack of guidelines for the use of compression therapy, elevation of legs, and regular exercise (77,3%) and consulting the angiologist last year (52,3% ). Regarding clinical features of the lesion was found that most of the recurrent lesions are (77,3%), over one year of current lesion (52,3%) medium to large lesions (54,8%), without signs of infection (61,3%) and pain (79,5%). The mean SE of respondents was 9,3 (± 5,1). The relations between the SE and the sociodemographic variables, health care and clinics showed that individuals without a partner (a) (p = 0,01), who did not wear compression therapy (p = 0,04), with more 6 months of treatment (p = 0,01) and larger lesions (p = 0,01) had a lower SE. The mean domain and the dimensions of the SF-36 were lower emphasizing the functional capacity 36.5 (± 27,6) and the physical aspects of 15.3 (± 30,6). There were significant correlations between AE people with VU and the domains and dimensions of the SF-36: physical functioning (r = -0,432), general health (r = -0,415), vitality (r = -0,573), aspects social (r = -0,517), mental health (r = -0,612) and mental health dimensions (r = -0,612) and physical health (r = -0,473). Based on these results it is concluded by rejecting the null hypothesis and accept the alternative proposed in the study in which it was found that there is a negative correlation between the SE and the QOL of people with venous ulcers

Aplicação superficial de calcário em pomar de laranjeira pêra em produção

A citricultura paulista é a maior do mundo, sendo de extrema importância manejos que visem a aumentar e melhorar a produção de frutos. Com vistas a isso, foi instalado na EECB (Bebedouro-SP), em um Latossolo Vermelho distrófico típico, um experimento com a aplicação de cinco doses de calcário calcinado, em julho/99. Os efeitos no solo foram avaliados através de amostragens nas camadas de 0-10; 10-20; 20-40 e 40-60 cm, aos 6; 12; 18; 24; 30 e 36 meses. Através da utilização de modelos lineares, constatou-se que os efeitos da aplicação superficial de calcário no solo podem atingir até a camada de 20-40 cm, sendo a saturação por bases uma ótima característica indicadora da ação do corretivo. A máxima reação do calcário ocorreu entre 12 e 18 meses após a aplicação. O estado nutricional das plantas e a produção foram alterados, significativamente em função da aplicação superficial de calcário, sendo que melhores respostas da planta foram obtidas com saturação por bases de aproximadamente 50%.

Avaliação de doses e produtos corretores da acidez em variáveis biométricas na produção de mudas de maracujazeiro

A utilização de produtos corretores da acidez do solo e a crescente busca por novos insumos agrícolas são de suma importância para uma agricultura sustentável e ecologicamente viável. O presente trabalho foi conduzido no viveiro de mudas do Setor de Fruticultura da Universidade Federal de Lavras (UFLA), Lavras, Estado de Minas Gerais. O delineamento experimental utilizado foi blocos casualizados em esquema fatorial 3 x 4, sendo três produtos, quatro doses e três repetições, as doses foram calculadas de modo que se atingisse a saturação estabelecida, de acordo com a concentração de cada produto. As doses foram: zero, metade, completa e o dobro da dose recomendada. A incubação foi realizada para o silício e calcário, e o Lithothamnium, pela liberação rápida, foi apenas incorporado ao solo. As características avaliadas foram: crescimento da parte aérea (mm), tamanho do sistema radicular (mm), número de folhas, matéria seca da parte aérea (mg), matéria seca da raiz (mg) e matéria seca total (mg). Os três produtos em questão proporcionaram mudas de qualidade, sendo a dose de 1,4 vezes a recomendada, a melhor para formação de mudas de maracujazeiro.

Suplementação protéica energética no desempenho de novilhas em pastejo durante a fase de terminação

Para estudar o efeito da suplementação da dieta sobre o desempenho de novilhas na fase de terminação mantidas em pastagem de capim-marandu sob lotação intermitente, durante a estação chuvosa, foram utilizadas 20 novilhas cruzadas (¼ Nelore, ¼ Santa Gertrudes, ½ Braunvieh) com peso corporal médio de 300 kg e 22 meses de idade. Os tratamentos constituíram-se de dois tipos de suplementação: sal mineral (SM) ad libtum e suplemento protéico energético (SPE) fornecido a 0,3% do peso corporal (PC) por dia com avaliações realizadas a cada 28 dias, no período entre dezembro de 2006 e março de 2007 Foram avaliados o desempenho animal e as características de carcaça medidas por ultrassom. Observou-se o efeito (P=0,057) da suplementação sobre o ganho de peso dos animais suplementados, 0,700 kg/dia e 0,587 kg/dia dos animais que receberam sal-mineral. Houve efeito da suplementação na área de olho de lombo e profundidade do músculo Gluteus medius. As demais características analisadas pela técnica de ultrassom não diferiram entre si em função da suplementação. A suplementação protéica energética da dieta permite ganhos adicionais, o que reflete em aumento da deposição de músculo de novilhas mantidas em pastagem de capim-marandu durante o período das águas.

Estudo da detecção do DNA do papiloma vírus humano (HPV) e da expressão imuno-histoquímica de proteína do ciclo celular no carcinoma epidermóide oral

Oral squamous cell carcinoma (OSCC) is the most common malignancy in oral cavity and human papillomavirus (HPV) may have an important role in its development. The aim of this experiment was to investigate the HPV DNA and viral types in 90 cases of OSCC. Moreover, a comparative analysis between the cases of OSSC with and without HPV DNA was performed by using cell cycle markers p21 and pRb in order to detect a possible correlation of these proteins and HPV infection. DNA was extracted from paraffin embedded tissue and amplified by PCR (polymerase chain reaction) with primers PCO3+ e PCO4+ for a fragment of human β-globin gene. After this procedure, PCR for HPV DNA detection was realized using a pair of generic primers GP5+ e GP6+. Immunohistochemical study was performed by streptoavidin-biotin technique and antibodies against p21 and pRb proteins were employed. Eighty-eight cases were positive for human β-globin gene and HPV DNA was found in 26 (29.5%) of then. It could not be detected significant correlation between HPV and age, sex and anatomical sites of the lesion. The most prevalent viral type was HPV 18 (80.8%). Regarding the immunohistochemical analysis, it was detected significant association between HPV presence and pRb immunoexpression (p=0,044), nevertheless, the same was not observed in relation to p21 protein (p =0,416). It can be concluded that the low detection of HPV DNA in OSCC by the present experiment suggests a possible role of the virus in the development and progression in just a subset of this disease

Effects of glass-forming histories on the crystallization kinetic of the 20Li(2)O-80TeO(2) glass

In the present work, tellurite 20Li(2)O-80TeO(2) glasses were prepared with identical nominal composition under different glass-forming histories to produce a stressed and stress-free samples. X-ray Diffraction (XRD) and Differential Scanning Calorimetry (DSC) techniques were used to study the effects of the glass-forming histories on the thermal and structural properties of these glasses. The gamma-TeO2 (metastable), alpha-TeO2 and alpha-Li2Te2O5 phases were identified during the controlled devitrification in these glasses. The mestastable character of the gamma-TeO2 phase was clearly observed in the glass under stress but this effect is not so clear in the stress-free glass. The gamma-TeO2 and alpha-TeO2 phases crystallizes during the initial stages of crystallization in both studied glasses while the alpha-Li2Te2O5 phase crystallize in the final stages of the crystallization. The activation energies and Avrami exponent were calculated for both studied glasses with different particle size leading to E-3 > E-2 > E-1 for stressed glass and E-3 > E-2 approximate to E-1 for stress-free glass, where E-1, E-2 and E-3 were associated to the gamma-TeO2, alpha-TeO2 and alpha-Li2Te2O5 phases, respectively. The observed distinct (n) over bar (1) < <(n)over bar>(2) < <(n)over bar>(3) in both glasses is an indicative that nucleation and growth takes place by more than one mechanism in the early stages of the crystallization.

Evaluation of Hemodynamic, Metabolic, and Electrolytic Changes After Graft Reperfusion in a Porcine Model of Intestinal Transplantation

Background. We sought to establish an anesthetic protocol to evaluate the hemodynamic, metabolic, and electrolytic changes after graft reperfusion in pigs undergoing orthotopic intestinal transplant (ITX).Methods. Fifteen pigs were distributed into two groups: GI (n = 6), without immunosuppression, and GII (n = 9), immunosuppressed before surgery with tacrolimus (0.3 mg/kg). The animals were premedicated at 1 hour before surgery with IM acepromazine (0.1 mg/kg), morphine (0.4 mg/kg), ketamine (10 mg/kg), and atropine (0.044 mg/kg IM). Anesthesia induction used equal proportions of diazepam and ketamine (0.1-0.15 mL/kg/IV) and for maintenance in IV infusion of xylazine (1 mg/mL), ketamine (2 mg/mL), and guaiacol glyceryl ether 5% (50 mg/mL), diluted in 250 mL of 5% glucose solution. In addition, recipient pigs were treated with isofluorane inhalation. Heart rate (HR), systolic (SAP), mean (MAP), and diastolic (DAP) arterial pressure, pulse oximetry, respiratory frequency (f), capnography, body temperature (T), blood gas analysis (pH, PaCO(2), PaO(2), base excess, BE; HCO(3)(-), SatO(2)), serum potassium (K), calcium (Ca), sodium, hematocrit (Hct), and glucose (Glu) were measured at four times; MO: after incision (basal value); M1: 10 minutes before reperfusion; and M2 and M3: 10 and 20 minutes after graft reperfusion.Results. All groups behaved in a similar pattern. There was significant hypotension after graft reperfusion in GI and GII (M2 = 56.2 +/- 6.4 and M3 = 57.2 +/- 8.3 mm Hg and M2 = 65.7 +/- 10.2 and M3 = 67.8 +/- 16.8 mm Hg, respectively), accompanied by elevated HR. The ETCO(2) was elevated at M2 (42 mm Hg) and M3 (40 mm Hg). Metabolic acidosis was observed after reperfusion, with significant increase in K levels.Conclusion. The anesthetic protocol for donors and recipients was safe to perform the procedure, allowing control of hemodynamic and metabolic changes after reperfusion without differences regarding immunosuppression.
