Os primeiros anos da Universidade Federal do Pará vistos através da Faculdade de Medicina.

O trabalho pretende apresentar as disputas entre grupos divergentes durante a criação da Universidade do Pará e os problemas da primeira reitoria, sob a ótica da Faculdade de Medicina, que representava uma força importante nesse período dentro do ensino superior do estado. Os conflitos existentes nos primórdios da instituição são tradicionalmente desconsiderados em abordagens mais convencionais

A disputa das Faculdades de Medicina imaginárias (Belém, Pará, década de 1950).

O artigo recorda o planejamento de duas Faculdades de Medicina em Belém (Pará) durante a década de 1950, geridas por grupos médicos divergentes, e as possíveis razões para que ambas não se tornassem realidade pelo menos naqueles anos

FACTORS ASSOCIATED WITH INFANT MORTALITY IN THE METROPOLITAN REGION OF CARIRI, CEARÁ, BRAZIL

Introduction: The identification of factors related to children’s deaths is very important in planning public health actions for restructure and improve the mother and child assistance, aimed in reducing child mortality. Objective: Analyze the factors associated with infant mortality in the metropolitan area of Cariri, Ceará, Brazil. Method: This is a cross-sectional study. All deaths occurring in children under one year old of the metropolitan region of Cariri, Ceará, Brazil, contained in the mortality information system and in live births’s information system, from January 2009 to December 2013. Newborn variables (sex, race/color, weight, age); maternal variables (maternal age and education and type of gestation); assistance variables (labor type) were extracted from the SUS (Sistema Único de Saúde/Unified Health System) Informatics Department and presented in chart and tables in absolute and percentage frequency form. Results: In the five-year period, 816 infant deaths in 48321 births were registered associated to the following factors: 453 (55.5%) male, 471 (57.7%) drab and 514 (63%) low weight in birth, 458 (56.1%) with 20 to 34 years of age, 353 (43.2%) 8 years or more of schooling, 657 (80.5%) only pregnancy and 414 (50.7%) vaginal birth. Conclusion: Infant mortality variables in the metropolitan region of Cariri, Ceará, Brazil were associated mostly with deaths occurring in drab boys with birth weight below the normal, whose mothers were young, with good education and who had just one gestation, born of vaginal birth

Topical Insulin Accelerates Wound Healing in Diabetes by Enhancing the AKT and ERK Pathways: A Double-Blind Placebo-Controlled Clinical Trial

Background: Wound healing is impaired in diabetes mellitus, but the mechanisms involved in this process are virtually unknown. Proteins belonging to the insulin signaling pathway respond to insulin in the skin of rats. Objective: The purpose of this study was to investigate the regulation of the insulin signaling pathway in wound healing and skin repair of normal and diabetic rats, and, in parallel, the effect of a topical insulin cream on wound healing and on the activation of this pathway. Research Design and Methods: We investigated insulin signaling by immunoblotting during wound healing of control and diabetic animals with or without topical insulin. Diabetic patients with ulcers were randomized to receive topical insulin or placebo in a prospective, double-blind and placebo-controlled, randomized clinical trial (NCT 01295177) of wound healing. Results and Conclusions: Expression of IR, IRS-1, IRS-2, SHC, ERK, and AKT are increased in the tissue of healing wounds compared to intact skin, suggesting that the insulin signaling pathway may have an important role in this process. These pathways were attenuated in the wounded skin of diabetic rats, in parallel with an increase in the time of complete wound healing. Upon topical application of insulin cream, the wound healing time of diabetic animals was normalized, followed by a reversal of defective insulin signal transduction. In addition, the treatment also increased expression of other proteins, such as eNOS (also in bone marrow), VEGF, and SDF-1 alpha in wounded skin. In diabetic patients, topical insulin cream markedly improved wound healing, representing an attractive and cost-free method for treating this devastating complication of diabetes.Sao Paulo Research Foundation (FAPESP)Sao Paulo Research Foundation (FAPESP)National Institute of Science and Technology (INCT)National Institute of Science and Technology (INCT)National Council for Scientific and Technological Development (CNPq)National Council for Scientific and Technological Development (CNPq
