Introduction: Hematopoietic stem cell transplantation (HSCT) often requires a central venous catheter (CVC) for quick and safe vascular access. Currently, new technologies are available to protect the catheter insertion site, such as chlorhexidine-impregnated gel dressings (CIGD). Objectives: To evaluate local cutaneous effects associated with CIGD in patients undergoing HSCT. Methods: In this cross-sectional, prospective study, we evaluated 25 HSCT patients who had a CVC inserted. Patients were visited daily to monitor the CIGD changing procedures and evaluate abnormalities of the underlying skin after dressing removal. Findings: Local erythema was the most frequently detected abnormality, although usually transient and considered secondary to the mechanical trauma of dressing removal. The most severe lesions, consisting of areas of skin loss, erythematous plaques and/or vesicles were classified as skin irritation and presented in 11 (44%) of the 25 patients. An association test showed that skin irritation was more frequent in patients who underwent allogeneic HSCT (p = 0.03). Skin irritation was most frequently observed in areas of contact with the non-woven polyester adhesive tape (n = 22; 88%), which made up the adhesive margins of the dressing. The CIGD was discontinued in 6 (54%) of the 11 patients who presented severe skin injuries. Conclusion: In this study, we detected that skin irritation was more frequent in patients who underwent allogeneic HSCT. The most common skin manifestation was skin loss.

Abstract: A computer software for image analysis (IMAGE PRO PLUS, MEDIA CYBERNETICS) was utilized in male and females adult worms, aiming the morphological characterization of Schistosoma mansoni samples isolated from a slyvatic rodent, Nectomys squamipes, and humans in Sumidouro, Rio de Janeiro, Brazil and recovered from Mus musculus C3H/He. The following characters for males's testicular lobes were analyzed: number, area, density, larger and smaller diameter, longer and shorter axis and perimeter and extension; for females: area, longer and shorter axis, larger and smaller diameter and perimeter of the eggs and spine; oral and ventral suckers area and distance between them in both sex were determined. By the analysis of variance (one way ANOVA) significant differences (p<0.05) were observed in all studied characters, except for the density of testicular lobes. Significant differences (p<0.05) were detected for all characters in the female worms. Data ratify that sympatric isolates present phenotypic differences and the adult female characters are useful for the proper identification of S. mansoni isolates.

Abstract: populations of synchaeta jollyae (shiel & koste, 1993) (rotifera), a species recently recorded for the first time in brazil and south america, were analyzed in reservoirs in southeast brazil. sampling was carried out monthly from august 2006 to july 2007 at furnas reservoir in the rio grande basin, state of minas gerais, and in four cascade reservoirs in the tietê river basin (barra bonita, bariri, ibitinga and nova avanhandava) state of s?o paulo, in june and september 2008 and in january and may 2009. synchaeta jollyae occurred in most samples and periods. from the results obtained it is evident that s. jollyae occurs in water bodies of varied trophic status but reaches larger populations in eutrophic water bodies and during lower temperature periods. the greatest densities of s. jollyae were found in the eutrophic bariri reservoir, on the tietê river, during the winter. mann-whitney test confirmed the significant difference between the population densities in periods of high and low temperatures, with populations reaching higher densities at lower temperatures. it is not yet possible to tell whether s. jollyae is a widely distributed species that has been overlooked in previous plankton studies in south america. wherever these populations of s. jollyae might have originated, it appears to be a species well established and adapted to a wide range of conditions in the neotropics.

Abstract: Female New Zealand rabbits (N = 12) were immunized with 1 mg/ml of collagen V in Freund's adjuvant (IM). After 150 days, six immunized animals were tolerated by nasal administration of collagen V (25 μg/day) (IM-TOL) daily for 60 days. The collagen content was determined by morphometry, and mRNA expressions of types I, III and V collagen were determined by Real-time PCR. The TGF-beta expression was evaluated by immunostaining and quantified by point counting methods. To statistic analysis ANOVA with Bonferroni test were employed for multiple comparison when appropriate and the level of significance was determined to be p < 0.05.IM-TOL, when compared to IM, showed significant reduction in total collagen content around the vessels (0.371 ± 0.118 vs. 0.874 ± 0.282, p < 0.001), bronchioles (0.294 ± 0.139 vs. 0.646 ± 0.172, p < 0.001) and in the septal interstitium (0.027 ± 0.014 vs. 0.067 ± 0.039, p = 0.026). The lung tissue of IM-TOL, when compared to IM, showed decreased immunostaining of types I, III and V collagen, reduced mRNA expression of types I (0.10 ± 0.07 vs. 1.0 ± 0.528, p = 0.002) and V (1.12 ± 0.42 vs. 4.74 ± 2.25, p = 0.009) collagen, in addition to decreased TGF-beta expression (p < 0.0001).Collagen V-induced nasal tolerance in the experimental model of SSc regulated the pulmonary remodeling process, inhibiting collagen deposition and collagen I and V mRNA synthesis. Additionally, it decreased TGF-beta expression, suggesting a promising therapeutic option for scleroderma treatment.Progressive Systemic Sclerosis (SSc) is an autoimmune disease of unknown pathogenesis, characterized by the increased extracellular matrix (ECM) synthesis, vascular remodeling and autoantibody emergence, which results in scarring in multiple organs. The lung is usually involved, and is the main cause of mortality in this disease [1]. Interstitial lung fibrosis, of variable intensity, affects approximately 90% of patients, and the frequency of pulmonary hypertension varies from

Abstract: El estudio tiene como objetivo describir los cuidados de enfermería al recién nacido y analizar las modificaciones en la atención de enfermería al recién nacido durante el período de 1937 hasta 1979. Se trata de un estudio histórico. Las fuentes primarias son 14 artículos publicados en la Revista Brasile a de Enfermería en el período en cuestión, y las fuentes secundarias son los libros y periódicos nacionales e internacionales con relación a la historia de la pediatría y de la neonatología. Es evidente, en este período, la descripción detallada de los cuidados directos (básicos y específicos) y los cuidados indirectos oferecidos por el equipo de enfermería al recién nacido. Entre los cuidados directos básicos, se destacan: higiene corporal y cuidados con el cordón umbilical. Los cuidados directos específicos son: infecciones y afecciones respiratórias. Los cuidados indirectos se relacionan con el material y el equipamiento. Se concluye que el discurso oficial de las enfermeras estuvo volcado para a la sistematización de los cuidados de enfermería al recién nacido, como pionera de los cuidados intensivos neonatales.

Abstract: Los objetivos del presente estudio son: evaluar la confiabilidad del Inventario de Necesidades y Estresores de Familiares de Pacientes en Cuidados Intensivos en 72 familiares de recién nacidos internados en una unidad de cuidados intensivos neonatales e identificar la importancia de dichas necesidades. El estudio cuantitativo, descriptivo y transversal se realizó durante el período de julio a septiembre de 2008. Para evaluar la importancia de las necesidades se calculó el promedio de cada subescala y del total de los ítems del instrumento, y para la confiabilidad se calculó el coeficiente alfa de Cronbach. El instrumento presentó satisfactorios valores de coherencia interna para todos los ítems y las subescalas del instrumento. Las necesidades consideradas como las de mayor importancia fueron las relacionadas con seguridad, información y proximidad. El conocer las necesidades de los familiares le permite al enfermero implementar acciones que garanticen una asistencia de mejor calidad a los recién nacidos y sus familias.
