Papel da eritropoetina recombinante humana sobre o metabolismo dos carboidratos, paratormônio, cálcio iônico, zinco, prolactina e níveis pressóricos em renais crônicos tratados com hemodiálise

Objective: To evaluate the influence of recombinant human erythropoietin (Epho) on carbohydrate metabolism, parathyroid hormone, calcium ionic, zinc, prolactin and blood pressure (BP) in chronic renal failure treated by hemodialysis. Methods: Ten patients in hemodialysis were followed during 24 weeks in two phases: 12 weeks pre-Epho (BP was measured pre and post hemodialysis sessions) and 12 weeks post-Epho (BP was measured as above and also the blood levels of glucose, insulin, parathyroid hormone, calcium ionic, prolactin, and zinc). Results: Patients were 39.8±8.5 y, 50% males. Hematocrit and hemoglobin presented a significant increase four weeks after Epho (22.3±2.3 to 28.1±2.6% and 7.4±0.8 to 9.4±0.9 g/dL, p<0.05). BP (mmHg) and weight pre-Epho: 158±99 and 59±13 (before hemodialysis), 147±96 and 55±13 (after hemo) and post-Epho: 161±100 and 59±13 (before hemo) 155±101 and 56±12 (after hemo) were all not statistically different in any moment. There are also no difference pre and post-Epho in fast glucose (91.8±6.5 and 90.8±6.1 mg/dL, p>0.05), parathyroid hormone (341.4±249.3 and 515.7±310 pg/ mL), calcium ionic (3,66±0.63 and 3.76±0.45 mmol/L), prolactin (males: 327±144.1 and 298.1 ±145.2 μg/mL; females: 666.2±426.6 and 659±395.3 μg/mL) and zinc (median of 0.73 and 0.71 μg\L). Basal insulin was lower after Epho (median of 9.1 to 3.8 μg/mL, p<0.05). Conclusion: These data suggest that recombinant human erythropoietin was effective to improve the anemia and the carbohydrate metabolism in patients with chronic renal failure treated by hemodialysis. © Copyright Moreira Jr. Editors.

Multiplicadores reflexivos: Uma experiância do Instituto Familiae junto ao Grupo de Assistância em Transtornos Alimentares (GRATA) do HC-FMRP-USP

This article describes the Reflecting Practitioners Program developed by Instituto Familiae at GRATA (Grupo de Assistência em Transtornos Alimentares) placed at the Clinical Hospital of the Faculty of Medicine of Ribeirão Preto - University of Sao Paulo (HC-FMRP-USP). The aim of this program was to take care of the caretakers - the GRATA interdisciplinary team - through the development of their reflecting ability, the appropriation of their own resources and the support on constructing alternative histories and on solving situations defined by them as problematic. Thirteen monthly meeting had been carried out among Familiae members and GRATA interdisciplinary team. The changes described by the participants had occurred through sessions developed with interdisciplinary pairs and through the development of their capacity to construct more comfortable positions - as members of the team and in the relationship among professional/client/ family. This triad became to be seen by the team through its resources and abilities, instead of its flaws and lacks. As a result, horizontal relationships could be privileged instead of hierarchical ones.

Diferenciação hepatocítica de células-tronco mesenquimais da medula óssea humana

Some recent articles have reported that mesenchymal stem cells (MSCs) can be induced to express hepatocyte markers by transplanting them into animal models of liver damage, or by in vitro culture with growth factors and cytokines. In this study, the aim is to evaluate the behavior of MSCs subjected to induction of hepatocyte differentiation. The MSCs were isolated from the bone marrow of 4 normal donors, characterized and subjected to both in vitro and in vivo induction of hepatocyte differentiation. The in vitro induced cells showed morphological changes, acquiring hepatocyte-like features. However, the immunophenotype of these cells was not modified. The induced cells exhibited no increase in albumin, cytokeratin 18 or cytokeratin 19 transcripts, when analyzed by real-time RT-PCR. The expression of albumin, cytokeratin 18 and alpha fetoprotein was also unchanged, according to immunofluorescence tests. In vivo, the MSC demonstrated a potential to migrate to damaged liver tissue in immunodeficient mice. Taken together, the results suggest that bone marrow MSCs are incapable of in vitro differentiation into hepatocytes by the approach used here, but are capable of homing to damaged hepatic tissue in vivo, suggesting a role for them in the repair of the liver. This contribution to tissue repair could be associated with a paracrine effect exerted by these cells.

Investigação sorológica de espécies de Ehrlichia em cães, equinos e humanos de um assentamento rural do sul do Brasil

The aims of this study were to determine the seroprevalence of Ehrlichia spp. and risk factors for exposure in a restricted population of dogs, horses, and humans highly exposed to tick bites in a Brazilian rural settlement using a commercial ELISA rapid test and two indirect immunofluorescent assays (IFA) with E. canis and E. chaffeensis crude antigens. Serum samples from 132 dogs, 16 horses and 100 humans were used. Fifty-six out of 132 (42.4%) dogs were seropositive for E. canis. Dogs > one year were more likely to be seropositive for E. canis than dogs ≤ one year (p = 0.0051). Ten/16 (62.5%) and 8/16 (50%) horses were seropositive by the commercial ELISA and IFA, respectively. Five out of 100 (5%) humans were seropositive for E. canis and E. chaffeensis. Rhipicephalus sanguineus (n = 291, 97.98%) on dogs and Amblyomma cajennense (n = 25, 96.15%) on horses were the most common ticks found. In conclusion, anti-Ehrlichia spp. antibodies were found in horses; however, the lack of a molecular characterization precludes any conclusion regarding the agent involved. Additionally, the higher seroprevalence of E. canis in dogs and the evidence of anti-Ehrlichia spp. antibodies in humans suggest that human cases of ehrlichiosis in Brazil might be caused by E. canis, or other closely related species.
