Infections for intestinal parasites are one of the main morbidade causes in humans and, its relationships with socioeconomic levels and hygiene conditions in countries in development are already very established. Many works, even so, they are being accomplished to elucidate the complex interactions among nutrition, these infections and answer imunológica, because it is seen that malnutrition commits the immunity increasing the susceptibilidade for infectious diseases and these for its time can harm the state human nutricional. It is known that sponge helmínticos they stimulate synthesis of IgE so much policlonal as specific for the same ones and that IgA secretora, main imunoglobulina of defense of the mucous ones, can act against protozoa as the Giardia lamblia and against helmintos as Trichuris tichiura and Strongyloides stercorales. Some studies show that the malnutrition energy protéica influences in the production of these answers, but some authors show results divergentes. In this work it was evaluated the levels of total IgE, IgA sérica and secretora, contagem of sanguine eosinófilos, levels of proteins séricas and state nutricional, in 103 children of low socioeconomic level, to discover a correlation between those and infection for enteroparasitas. They participated in the study children of both sexes, with age of 3 to 6 years, visitors of the same creche and residents in a neighborhood with precarious hygiene conditions and basic saneamento, in the city of Christmas. The obtained results showed that the faulty environmental and socioeconomic conditions favored to a high infection frequency for enteroparasitas, mainly Trichuris trichiura and Ascaris lumbricoides between the helmintos and Endolimax sleep and Giárdia lamblia among the protozoa. Light malnutrition without deficit protéico was observed in 30% of the children, which didn't also present significant deficiencies of IgA sérica and secretora. The sponged children

The exclusive breastfeeding in the first six months of life practice is essential for the health and development of children. Studies show there is in human milk protective antibodies against intestinal parasites and a relationship between the absence of breastfeeding or weaning and parasitic infections. This work was a prospective cohort study involving 34 pregnant adolescents attended school in Maternity Januario Cicco / RN and their children, to assess the influence of breastfeeding on intestinal parasites in them. Thus, the parasitic infection was investigated by examination of feces parasitological and environmental factors by use of questionnaires. The average age of the mothers studied was 16.2 years. Of these 76.4% were infected and the most prevalent species of parasites were Entamoeba histolytica/dispar (76.9%), Giardia lamblia (19.2%) and Ascaris lumbricoides (11.5%). The infected children had an average age of 5.1 months and the frequency of parasites was 61.7%. The infection was earlier detecctada with 45 days of life. The most common parasites were Giardia lamblia (40%), Entamoeba histolytica/dispar (35%), Ascaris lumbricoides (5%) and Ancylostoma (5%). The average length of exclusive breastfeeding was 2.2 months. There was an association between increased duration of exclusive breastfeeding and increased time to detection of parasites in the feces of children. There was no statistically significant correlation between the socio-economic conditions and cultural and breastfeeding. The data reinforce the importance of breastfeeding to protect the children in its first year of life

Natural oils have shown a scientific importance due to its pharmacological activity and renewable character. The copaiba (Copaifera langsdorffii) and Bullfrog (Rana catesbeiana Shaw) oils are used in folk medicine particularly because the anti-inflammatory and antimicrobial activities. Emulsion could be eligible systems to improve the palatability and fragrance, enhance the pharmacological activities and reduce the toxicological effects of these oils. The aim of this work was to investigate the antimicrobial activity of emulsions based on copaiba (resin-oil and essential-oil) and bullfrog oils against fungi and bacteria which cause skin diseases. Firstly, the essential oil was extracted from copaiba oil-resin and the oils were characterized by gas chromatography coupled to a mass spectrometry (GC-MS). Secondly, emulsion systems were produced. A microbiological screening test with all products was performed followed (the minimum inhibitory concentration, the bioautography method and the antibiofilm determination). Staphylococcus aureus, S. epidermidis, Pseudomonas aeruginosa, Candida albicans, C. parapsilosis, C. glabrata, C. krusei and C. tropicalis American Type Culture Collection (ATCC) and clinical samples were used. The emulsions based on copaiba oil-resin and essential oil improved the antimicrobial activity of the pure oils, especially against Staphylococcus e Candida resistant to azoles. The bullfrog oil emulsion and the pure bullfrog oil showed a lower effect on the microorganisms when compared to the copaiba samples. All the emulsions showed a significant antibiofilm activity by inhibiting the cell adhesion. Thus, it may be concluded that emulsions based on copaiba and bullfrog oils are promising candidates to treatment of fungal and bacterial skin infections

No período compreendido entre 1985 e 1996 foram necropsiados, para pesquisa de helmintos, 42 cervídeos, sendo sete Mazama americana, 16 M. gouazoubira, 13 Ozotoceros bezoarticus e seis Blastocerus dichotomus. Desses animais, foram colhidos 14.426 nematódeos Trichostrongyloidea, sendo 13.281 (92,06%) parasitos de abomaso e 1.145 (7,94%), de intestino delgado. Nesses órgãos, foram identificadas seis espécies de nematódeos: Haemonchus contortus, H. similis, Trichostrongylus axei, T. colubriformis, Cooperia punctata e C. pectinata. Todos os animais apresentaram infecções helmínticas por uma ou mais espécies, ocorrendo grande variação na intensidade de infecção (1 a 4.345 nematódeos). Ainda com relação à intensidade de infecção, os dados expressavam valores menores que 100 parasitos em 25 (59,52%) animais. Os valores mais altos de intensidade média das infecções foram observados em M. gouazoubira (596,37 helmintos) e em O. bezoarticus (331), e os menores, em M. americana (17,57) e B. dichotomus (75,5). Os dados mais expressivos de intensidade de infecção, abundância e prevalência foram observados para Haemonchus (larvas de 4º estágio), H. contortus, H. similis e T. axei. O gênero Haemonchus foi constatado em 35 animais, com prevalência de 83,33%; apresentou carga parasitária de 11.616 exemplares, representando 80,52% dos nematódeos verificados, sendo a maioria (8.903) constituída por formas imaturas. Por outro lado, H. similis foi a espécie predominante nas infecções e, portanto, a que apresentou maiores valores de abundância. Verificou-se o gênero Trichostrongylus em 24 (57,14%) animais, com carga parasitária de 2.444 exemplares, sendo 1.665 espécimes de T. axei, que representou 11,54% da carga parasitária obtida. As seis espécies de vermes identificadas nos cervídeos são comuns aos ruminantes domésticos nos Estados de São Paulo e Mato Grosso do Sul e dessa maneira não se observou nenhuma espécie de Trichostrongyloidea exclusiva dos cervídeos.

In recent decades, the search for quality care has been widely discussed by the institutions and health professionals. In this context, it is the nurse coordinator of the process of providing nursing staff, reflecting the commitment to quality of care. In this process, it is the appearance of Infections Related to health care and its potential association with the workload in nursing as a valuable indicator of quality of care. Thus, this research contributes to studies to characterize the demand of nursing work to promote a safe healthcare practice. This study aimed to identify the association of nursing workload with the number of cases of Ventilator-Associated Pneumonia, urinary tract infection and central venous catheter infection in the intensive care unit. This is a quantitative research approach, descriptive, cross-sectional and prospective, held at Unimed Hospital in Natal-RN. The study population consisted of all patients treated in the Intensive Care Unit, Hospital for a period of 90 consecutive days in 2011. The convenience sample was compostapelos patients admitted to the ICU during the period of data collection, a total sample of 286 patients. To perform the data analysis software were used: Statistica 6.0, SPPS (Statistical Package for Social Sciences) version 17.0 (2004) and Excel 2007. In the descriptive analysis, we used Measures of Central Tendency and Measures of Dispersion or Variability and the use of nonparametric tests. Of the 286 patients, 88 were from the ICU and 198 ICU II II. Males predominated in the ICU I (51.1%) and female ICU II (57.6%) patients in the ICU I were aged 61-80 years (39.8%) followed by greater than 80 years (39.8%). In the ICU II, most of the patients were aged 61-80 years (38.9%) and then from 41 to 60 years (24.2%). In relation to the class of TISS inlet predominant class II in the two ICUs (59.1%), followed by Class III also in the two units (34.6%). Most patients (70.6%) out of the ICUs belonging to class II TISS. In the ICU I, the average number of forms of the TISS 28 was 6, has in ICU II this value drops to 3.2 forms. The overall mean was 19.9 TISS points in ICU patients I and ICU II.the 17 points in the average hours required to provide adequate nursing care to patients in the ICU I found that is 10 , 7 hours, and the ICU II 9.2 hours. It was found that the time provided by the nursing staff were higher in ICU II, with an average of 19 hours available for nurses in this sector. In the ICU I, which showed higher need of available hours, it was found that the mean value of 12.7 available hours. It was found that only 2.4% of patients had these units Ventilator-Associated Pneumonia, 1.0% were infected central venous catheter and 1.4% of patients had urinary tract infection. Infection associated with health care occurs, on average, on the tenth day of hospitalization. In the ICU II, this average value extends to the twelfth day with an excess of 2.7 hours of nursing care while in ICU I value decays to the ninth day of hospitalization with a deficiency of 12-hour assistance. It is concluded that patients generally showed a need for classification of semi-intensive care and has been assisted in their need to load. As for his association with the Related Infections Health will assist this analysis could not be performed due to the small number of notifications in this period. It is suggested further study how other factors related to infections me a longer period of analysis

Estimaram-se os componentes de variância do período de gestação (PG) considerando-se o efeito direto do bezerro e os efeitos direto da vaca e aleatório do touro (pai do bezerro). Além dos efeitos aleatórios, os modelos estatísticos incluíram os efeitos fixos de grupo de contemporâneos, composto pela data juliana de inseminação, ano de nascimento e sexo do bezerro, e a idade da vaca ao parto (covariável linear e quadrática). As médias de PG para os animais da raça Nelore foram 294,55 dias (machos) e 293,34 dias (fêmeas) e para os animais cruzados, 292,49 dias (machos) e 292,55 dias (fêmeas). Os componentes de variância observados no Nelore, utilizando-se o modelo 1, que considerou o PG como característica do bezerro, foram 14,47; 72,78 e 57,31 para os componentes aditivo direto (sigma2a), fenotípico total (sigma2p) e residual (sigma2e), respectivamente, e a herdabilidade foi 0,21. Para os animais cruzados, pelo mesmo modelo, os componentes de variância foram 90,40 (sigma2a), 127,35 (sigma2p ) e 36,95 (sigma2e), e a herdabilidade, 0,71. Os componentes de variância do PG do Nelore sob o modelo 2, que considerou o PG como característica da vaca, foram 12,78; 5,01; 74,84 e 57,05, para sigma2a; sigma2pb (variância do pai do bezerro); sigma2p e sigma2e, respectivamente. A fração fenotípica atribuída ao touro (c²) foi 0,07 e a repetibilidade, 0,17. Para os cruzados, estimaram-se 22,11; 22,97; 127,70 e 82,61 para sigma2a; sigma2pb; sigma2p e sigma2e, respectivamente, enquanto o c² foi 0,18 e o coeficiente de repetibilidade, 0,17. Sugere-se, para fins de seleção, que o coeficiente de herdabilidade utilizado seja o obtido na análise em que PG foi considerado como característica do bezerro.

The subjective well- being (SWB) is formed by global judgments of satisfaction with life, or with peculiar domains the positive and the negative emotional experiences. The perception in turn, is the process of interpretive process of sensory data with cognitive or informative sense, absorbed in function of a context. From this perspective, the research aimed to evaluate SWB and the perception of advanced age pregnant women. Participated in the survey 80 pregnant with 35 years old or older (Group A or older) and 80 pregnant aged between 20 and 34 years old (Group B or young adults). The instruments used were: the scale of subjective well-being and a questionnaire, that included sociodemographic informations, items about pregnancy and a statement based on the Free Association of Words Technique (FAWT) to approach the perception of pregnancy. The data from the questionnaire and scale, in order to compare the data between groups suffered descriptive and inferential statistical analyzes. The analyzes performed with chi-square test among groups, which had values that were statistically significant, with the sociodemographic variables the type of contraceptive and health problems. The indicators of the SWB had further more by means in groups. The results of the Wilcoxon's test that there were no differences between the groups referred above. In the relation indicators of well being with variables age, education and income, some associations were significant. In addition, the words derived from the (FAWT) were analyzed using the software Programmer s Permenttant l´Analyse des Evocation (EVOC2000) and categorized according to content analysis of Bardin in three thematic categories (positive and negative affects, perception of gestation and implications of pregnancy) discussed as a group, since most of words were common. The study highlights shown how similar were the presented data by pregnant women surveyed. It is supposed about this fact the similarity is related to the social context. The relevance of this study for the health care network is to help with proposals aimed at specific improvements to the public and the sector, beside demonstrate that advanced age pregnant women and young adulst in the researched context showed no differences in the most of the studied characteristics

OBJETIVO: Observar se diferentes graus de hiperglicemia durante a gestação determinam diferentes freqüências de obesidade e suas comorbidades na adolescência dos filhos. MÉTODOS: Participaram 73 filhos distribuídos em três grupos, segundo a tolerância à glicose materna: G1 (n = 27) teste oral de tolerância à glicose (TOTG) e glicemia diária (GD) normais; G2 (n = 23) TOTG normal e GD elevada; G3 (n = 23) TOTG e GD alterados (diabetes melito ges tacional - DMG). Todos foram submetidos à avaliação clínica (antropometria), a um questionário (dados neonatais, hábitos alimentares) e a dosagem basal de glicose e perfil lipídico sérico. A comparação entre os grupos foi feita por análise de variância e teste de Goodman. RESULTADOS: As mães G3 apresentaram glicemia de jejum (GJ) e GD mais elevadas que as G2 e G1 (GJ: 98 ± 10 versus 83 ± 5 versus 78 ± 10 mg/dL; GD: 104 ± 12 versus 93 ± 7 versus 85 ± 9 mg/dL, respectivamente; p < 0,001). As mães G2 apresentaram GD mais elevada que as G1 (93 ± 7 versus 85 ± 9 mg/dL; p < 0,001). O peso de nascimento (PN) dos filhos G3 foi mais elevado que o dos G2 e G1 (3.667 ± 527 versus 3.167 ± 565 e 3.282 ± 401 g, respectivamente; p < 0,05). Os filhos G3 apresentaram maior freqüência de sobrepeso que os G1 (52,2 versus 14,8%; p < 0,05). CONCLUSÕES: Mães com DMG, apresentando GJ e GD elevadas, têm filhos com maior PN e maior freqüência de sobrepeso na adolescência. Esses filhos precisam ser acompanhados desde a infância.

Helicobacter pylori is the main cause of gastritis, gastroduodenal ulcer disease and gastric cancer. The most recommended treatment for eradication of this bacteria often leads to side effects and patient poor compliance, which induce treatment failure. Magnetic drug targeting is a very efficient method that overcomes these drawbacks through association of the drug with a magnetic compound. Such approach may allow such systems to be placed slowed down to a specific target area by an external magnetic field. This work reports a study of the synthesis and characterization of polymeric magnetic particles loaded with the currently used antimicrobial agents for the treatment of Helicobacter pylori infections, aiming the production of magnetic drug delivery system by oral route. Optical microscopy, scanning electron microscopy, transmission electron microscopy, x-ray powder diffraction, nitrogen adsorption/desorption isotherms and vibrating sample magnetometry revealed that the magnetite particles, produced by the co-precipitation method, consisted of a large number of aggregated nanometer-size crystallites (about 6 nm), creating superparamagnetic micrometer with high magnetic susceptibility particles with an average diameter of 6.8 ± 0.2 μm. Also, the polymeric magnetic particles produced by spray drying had a core-shell structure based on magnetite microparticles, amoxicillin and clarithromycin and coated with Eudragit® S100. The system presented an average diameter of 14.2 ± 0.2 μm. The amount of magnetite present in the system may be tailored by suitably controlling the suspension used to feed the spray dryer. In the present work it was 2.9% (w/w). The magnetic system produced may prove to be very promising for eradication of Helicobacter pylori infections
