Qualidade de vida de pessoas com úlcera venosa: associação dos aspectos sociodemográficos, de saúde, assistência e clínicos da lesão

Venous ulcer (VU) is a lower limbs injury resulting from inadequate return of venous blood in feet or legs. Although it is not a deadly disease, it causes chronic wounds, which seriously undermine patients´ quality of life (QOL) and sometimes leads to drastic family, social, economic and psychological changes. In this sense, there are several aspects that may influence the venous ulcers patients´ QOL. The study´s objective aimed on the association of socio-demographic and health, health care and clinical injury on UV patients‟ QOL. Analytical studies, which consider the complexity of factors involved in changes in UV patients‟ QOL has a cross-sectional and quantitative approach. The HUOL Ethics Committee approved this project (n.279/09). The collection of data lasted a period of 3 months in 2010 and it took place at the clinic of Angiology at Hospital Universitário Onofre Lopes (HUOL). The data sample consisted of 60 patients treated by UV angiologists in the HUOL Surgical Clinic. The results were analyzed with SPSS 15.0 by descriptive and inferential statistics. The study was based on UV patients that were predominantly female, average age of 61.4 years, that had low education level and low family income, with occupations requiring long periods of standing or sitting, but mostly retired, unemployed or laid off due to the disease and/or due to chronic diseases associated with the UV. The study took also into consideration patients that used inappropriate products, that were improperly treated by a professional caregiver, that lacked of adequate guidance and compression therapy, that performed no lifting of the lower limbs and regular exercise, that the time of injury were greater than or equal to six months, that were missing specific laboratory tests. The study‟s reference were on recurrent lesions, medium to large lesions area, bed of the lesion (injuries) with fibrin and/or necrosis, with amount of exudate with medium to large, odorless and no signs of infection, with tissue loss between 1st and 2nd degree, without collecting swab or biopsy and with pain. In general, QOL of researched individuals were considered low, the maximum score was 69 points, which the areas that were mostly influenced were the total scores of QOL functional capacity (0.021), emotional (0.000) and social functioning (0.080). Of the 60 individuals, 53.3% had scores between 40 and 69 points in SF-36, and they had the best scores in sociodemographic and health variables (ρ = 0.049). In respect to the assistance and injury characteristics, patients who scored between 40 and 69 points in SF-36 had better scores on these characteristics. By combining the socio-demographic variables, health, and handling characteristics of the injury, we observed a significant difference (ρ = 0.032) when linking them with the QOL total scores. When analyzing separately the domains of the SF-36 scores on the quality of life, we find that the areas that showed statistical significance were functional ability (ρ = 0.035), appearance (ρ = 0.019), emotional (ρ = 0.000), and mental health (ρ = 0.050). Among the socio-demographic characteristics studied, gender and marital status contributed more to the reduction of QOL and among the variables of assistance and the injury, orientation, reference and area of UV contributed the most. By analyzing these five variables all together in accordance with the overall score obtained in the quality of life, we found a significant correlation (ρ = 0.002); with 6.23 times more chances of patients have better QOL in the presence of these five positive factors. By conducting the Mann Whitney U test between all the five demographic variables, health, and clinical care, we found that this combination also proved to be significant (ρ = 0.006). Therefore, patients with these five variables positive tend to have a better QOL. Based on these results, we reject the null hypothesis (H0) and accept the alternative hypothesis (H1) proposed in this study because we noted that the QOL of patients with UV is associated with sociodemographic and health, health care and clinical aspects of the injury

Qualidade da carne ovina submetida ao processo de salga

Foi estudada a qualidade da carne ovina submetida a diferentes teores de sal no processo de salga, utilizando-se 18 pernas desossadas provenientes de cordeiros ½ Ile de France ½ Ideal, machos inteiros, com peso vivo médio de 30kg. Os tratamentos constituíram-se em: T1 - controle; T2 - salga a 15% e T3 - salga a 20%. As mantas de carne foram lavadas rapidamente em água corrente para remoção do excesso de sal e secadas à sombra. As análises foram realizadas antes da salga e 67 horas após o início da mesma. As perdas de peso ao cozimento, maciez, cor, umidade (2, 4, 16, 28, 40 e 67 horas após o início da salga) e número de TBARS, substâncias reativas ao ácido 2-tiobarbitúrico, foram realizadas no músculo Semimembranosus. Os diferentes teores de sal não influenciaram (P>0,05) na luminosidade da carne, entretanto os teores de vermelho e amarelo, que foram influenciados (P<0,05). As perdas de peso ao cozimento e a umidade foram menores (P<0,05) nas carnes salgadas. A carne dos tratamentos controle e com 15% de salga, apresentou maior (P<0,05) maciez, em relação à carne do tratamento com 20% de salga. A carne que foi submetida a 20% de salga, apresentou maior oxidação lípidica, não diferindo da salga a 15%. A salga a 15% forneceu melhores resultados com valores de perdas de peso ao cozimento, cor, umidade e número de TBARS semelhante a salga a 20%, porém com maior maciez.

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

Energy and lysine for broilers from 44 to 55 days of age

An experiment was conducted to evaluate the performance and carcass yield of broilers at 55 days of age fed diets with different levels of metabolizable energy and lysine. Evaluated data of performance were weight gain, feed intake, energy intake, lysine intake, caloric conversion and feed conversion. Carcass assessment was performed based on data from carcass yield, breast weight, whole wings, whole legs, back, head + neck, feet and abdominal fat. A 3 x 3 factorial arrangement was used, with 3 levels of metabolizable energy (3,200; 3,400 and 3,600 kcal ME/kg) and 3 lysine levels (0.95%; 1.05% and 1.15%). There was no interaction between the two factors. Nevertheless, increasing levels of metabolizable energy improved weight gain (745 g; 841 g and 910 g, respectively) and feed intake was higher in broilers receiving the diets with 3,200 and 3,600 kcal ME/kg. Overall performance was not affected by lysine levels. Feed conversion values were 2.69, 2.42 and 2.14 for birds fed diets with 3,200; 3,400 and 3,600 kcal ME/kg, respectively. Carcass yield and breast weight increased with higher levels of energy and lysine in the diets.

Diferentes Perfis de Aminoácidos para Frangos de Corte no Período de 43 a 56 Dias de Idade

Um experimento foi conduzido para avaliar o desempenho e rendimento de carcaça de duas marcas comerciais de frangos de corte alimentados com diferentes perfis de aminoácidos. Dados de desempenho (ganho de peso, consumo de ração e conversão alimentar), carcaça (rendimento de carcaça, peito, pernas, dorso, asas, pés, cabeça e gordura abdominal) e vísceras comestíveis (moela, fígado e coração) foram coletados. O experimento foi realizado no período de 43 a 56 dias de idade e o delineamento experimental foi inteiramente casualizado em esquema fatorial 2x4 (duas marcas comerciais -- Hubbard e HI-Yield, e quatro perfis de aminoácidos - NRC (1994), Rostagno et al. (1992), Degussa (1997) e AEC (1993)), com quatro repetições de 50 aves cada. Quando as diferentes recomendações foram comparadas, o nível de lisina foi mantido constante, utilizando o nível do NRC (1994) como padrão. As aves alimentadas com dietas formuladas segundo recomendações do NRC (1994) apresentaram menor ganho de peso e pior conversão alimentar. As aves da marca comercial Hubbard apresentaram melhor ganho de peso, porém o consumo e a conversão alimentar não foram alterados. O rendimento de carcaça não diferiu entre os tratamentos. Contudo, as aves da marca comercial Hubbard apresentaram melhor rendimento de pernas e as aves HI-Yield, melhor rendimento de peito. A gordura abdominal foi afetada pelos tratamentos estudados em que aves da marca comercial Hubbard e alimentadas de acordo com os níveis recomendados pelo AEC (1993) apresentaram menor porcentagem de gordura abdominal. Não ocorreu efeito significativo para as vísceras comestíveis.

Study of postures in sugarcane cutters in the Pontal of Paranapanema-SP, Brazil

The expansion of sugarcane monoculture in Brazil in the last decades has pointed out to the necessity of considering the question of sugarcane cutters occupational health. In this work we present a cross-sectional study aiming to examine the occupational posture of a group of sugarcane cutters, which work in a cane field located in the region of Pontal do Paranapanema-SP, Brazil. The study was made using the Ergonomic Analysis of Work - EAW methodology and the postural analysis method by Win-OWAS. Through the obtained records of postures, it was observed that during a workday the sugarcane cutters remain standing erect on two legs or in one leg 66% of the time and that their trunk remain tilted and in rotation, according to 63% of the positions categorized. It was also observed that the sugarcane cutter trunk performs repetitive and boundless movements during his routine of work, which can expose this individual to additional wear of their musculoskeletal functions. The activities in which the individual engages have favorable or adverse influence on his posture. The repetitive movements involved in specialized occupations are equivalent to repeated exercises, thus may be responsible for the excessive development of certain muscle groups. The study suggests that the postures adopted by sugarcane cutters can overload their musculoskeletal system and predispose the cutters to work-related musculoskeletal diseases.

Efeitos imediatos da eletroestimulação nervosa transcutânea e crioterapia na espasticidade e na atividade eletromiográfica de sujeitos hemiparéticos

Cerebrovascular accident (CVA) is a term used to characterize an ischemic or hemorrhagic vascular injury, which has got as main clinic manifestations, the motor and reflex function disturbance. In the first stage there is flaccidity and loss of voluntary movements that afterwards is substituted by mass patterns and spasticity. The spasticity brings with itself functional deficits and can generate negative impacts in various motor patterns. The aim of this research was to investigate the hyperreflexia and identify the immediate effects of transcutaneous nervous stimulation (TENS) and cryotherapy in the spasticity and electromyographic activity of hemiparetic subjects. The study is characterized as an almost experimental type, in which were selected, to compose the sample, 16 patients of both sex with CVA sequel. These individuals were evaluated by collecting the amplitude peak to peak and H reflex latency, Motor response (M response) in solear muscle and the electromyography (EMG) of the injured and healthy legs anterior tibial muscles. In the injured limb the evaluations occurred in different days for cryotherapy, TENS and control, in two moments, before and after the interventions. The healthy limb was evaluated one single time to serve as baseline, for comparison with the injured limb. It was used an statistic analysis, the t paired student test to identify the H reflex differences, latency and EMG of the injured and healthy limbs and to compare the results before and after the recourses application. The ANOVA for related samples was used to identify the differences among the recourses used. It was attributed for the statistic tests a significance level of 5%. The amplitude peak to peak of normalized maximum H reflex through the maximum motor response (Hmax/Mmax), showed itself significantly increased in the injured limb (p=0.0245). The H reflex latency was presented reduced in the injured limb (p=0, 0375). The electromyographic activity was showed decreased in the injured limb (p< 0.0001). After the TENS there was a Hmáx/Mmáx ratio decrease (0.60±0.16 versus 0.49.±0.18; P = 0.0006). Nonetheless, Just after the cryotherapy application there was an increase of Hmáx/Mmáx ratio (0.58 ± 0,15 to 0.77 ± 0.13, P=0,0007) and increase of signal latency (30.41 ± 1.87 versus 33.24 ± 2.19; P=0.0001). The electromyographic activity wasn t altered significantly by any resource. It was met statistic significant differences when the Hmáx/Mmáx P<0.0001) ratio and H reflex latency (P<0.0001) were compared between the post TENS, cryotherapy and control. One can conclude that the TENS can be used to spasticity immediate reduction, and that the cryotherapy can increase the hyperreflexia state in spastic patients. Nonetheless, the spasticity decrease or increase didn t provoke lectromyographic activity change in the muscle that is opponent to the spastic one

Efeito do treinamento resistido na pressão arterial e capacidade funcional de idosas hipertensas

The results of studies about the ideal resistance training intensity for reduction of resting blood pressure levels, as well as this type of training to increase the functional capacity of hypertensive older women are still unclear, since the few investigations usually analyze young individuals normotensive, and the literature lacks precise information in elderly hypertensive subjects. Objectives: To determine the effect of two resistance training intensities on resting blood pressure and the effect of resistance training on functional capacity in elderly women with systemic arterial hypertension, analyzing these variables before and after eight weeks of intervention. Methods: Patients underwent eight weeks of resistance training, with a frequency of three times per week on alternate days, in the afternoon. The exercises performed were: leg press, bench press, knee extension, lat pull-down, knee flexion, shoulder abduction, standing cable hip abduction and biceps curl. Results: It was found that patients who underwent training with moderate resistance, showed a reduction on resting values of diastolic blood pressure (DBP) p<0.03 and of mean arterial pressure (MAP) p<0.03. Patients who underwent mild resistance training showed reduction in resting values of MAP (p<0.03) and a tendency to decrease in DBP (p<0.06). With regard to functional capacity, the results showed significant increase in the strength of arms and legs, agility and aerobic endurance (p<0.001) and maintaining flexibility (p>0.05). Conclusion: The data indicated that both mild and moderate resistance training, even when started in old age, promoted cardiovascular benefits and also improve the functional capacity of hypertensive older women.

Características da carcaça e qualidade da carne de ovinos terminados em pastagens cultivadas

The objective of this study was to evaluate the quality of housing and the physical and chemical characteristics of meat from sheep raised on pasture Brachiaria brizantha and Panicum maximum. The experiment was conducted in the physical area of the Study Group on Forage (GEFOR), located in the Academic Unit Specialized in Agricultural Sciences - Federal University of Rio Grande do Norte - UFRN in Macaíba, RN, Brazil. We used 32 lambs SPRD, obtained from herds in the state, with liveweight (LW) of 24.5 kg were assigned randomly to four treatments consisting of tropical grasses, two cultivars of Brachiaria brizantha, Marandu and Piatã, and two of Panicum maximum, Aruana and Massai. The experimental area was 2.88 ha, divided into 4 paddocks of 0.72 ha, where each picket consisted of a farm and was divided into six plots of 0.12 ha, where the animals remained under rotational grazing. The period of adaptation to the pickets was seven days. At the beginning of the experiment the animals were weighed, identified with plastic earrings and necklaces colored according to the treatment, and treated against. The lambs were loose in the paddock at 8 am and collected at 16 hours, which returned to collective pens. During the time of grazing animals had free access to mineral supplement with monensin Ovinofós ® and water. Before entering the paddocks of pasture were sampled to characterize the chemical composition. Every seven days occurred at weighing, with fasting, to monitor the weight development. Cultivars Marandu, Aruana, Piatã and Massai were grazed for 133, 129, 143 and 142 days, respectively, until the lambs reach slaughter weight. Arriving at 32 kg lambs were evaluated subjectively for body condition score by, passed through fasting period, diet and water for 16 hours were slaughtered. Measurements were made in the inner and outer casings in addition to subjective evaluations regarding muscling, finish and quantity of pelvic-renal fat, then each was divided longitudinally into two half-carcases and cuts were made in the commercial left half, and after heavy calculated their income. Between the 12th and 13th thoracic vertebrae, was performed a cut to expose the cross section of the Longissimus dorsi, which was drawn on the rib eye area (REA) in transparent film. Fat thickness and extent of AOL GR were determined using a caliper. A tissue composition was determined by dissection of the legs. Analyzes were performed physical (color, cooking loss and shear force) and chemical composition of meat (moisture, ash, protein and lipids) in Longissimus dorsi muscle. Grazing tropical grass Brachiaria brizantha cvs. Marandu and Piatã and Panicum maximum cvs. Aruana and Massai can be used for lambs SRPD in the rainy season, because not alter the physico-chemical and chemical composition of meat

Agricultura familiar: uma perspectiva da qualidade de vida do produtor rural orgânico da Paraíba

Knowledge of quality of life is a very complex and rich in cultural and subjective dimensions, understood in a broad sense and multivariate theme. Considering the rural areas from agriculture, it is observed that the production standard defines significant changes in the environmental context and the quality of life of rural workers. To explain the relationship between quality of life and Family Organic Agriculture, we sought to analyze the quality of life of the organic family farmer, after change in agricultural management. The research, based on a procedure exploratory study supported the articulation theoretically constructed, showed their relevance and allowed to delimit with greater security, the central question of work. The WHOQOL - 100 treated the instrument of research on quality of life that directed the field study with organic farmers from the town of Lagoa Seca / PB. Farmers and family members are from rural regions Almeida, Alvinho, Lagoa de Barro, Lagoa Gravatá, Oiti and Pau Ferro. The average time is 39 years farming and organic family farm is 16 years. In the analysis work was found that the process of production of vegetables and fruits is divided into 08 steps and with respect to workloads observations showed the presence of: physical loads, mechanical stresses, psychological burden and ergonomic factors. Most farmers reported symptoms were fatigue and cramps in the legs . Regarding the quality of life was noticed that the Psychological Domain contributed positively to the quality of life with mean and standard deviation (17.83 ± 12.78) and Domain Environment negatively contributing to the quality of life of this group (9.00 ± 6.82). We conclude that the practice of Family Organic Agriculture should be seen as an effective strategy in promoting quality of life and social values in between, since it presents environmental sustainability with regard to life and socio-cultural diversity of populations
