Effectiveness and safety of a new vaginal misoprostol product specifically labeled for cervical ripening and labor induction

Objective. The purpose of this study was to evaluate the effectiveness and safety of misoprostol in two different formulations: vaginal tablets of 25 mu g and one-eighth of a 200-mu g oral tablet, also administered intravaginally, for cervical ripening and labor induction of term pregnancies with an indication for that. Methods. A single-blind, randomized, controlled clinical trial was carried out in 120 pregnant women who randomly received one of the two formulations. The main dependent variables were mode of delivery, need for additional oxytocin, time between beginning of induction and delivery, perinatal results, complications, and maternal side effects. Student's t, Mann-Whitney, chi(2), Fisher's Exact, Wilcoxon and Kolmogorov-Smirnoff tests, as well as survival analysis, were used in the data analysis. Results. There were no significant differences between the groups in terms of general characteristics, uterine contractility, and fetal well-being during labor, cesarean section rates, perinatal outcomes, or maternal adverse events. The mean time between the beginning of cervical ripening and delivery was 31.3 h in the vaginal tablet group and 30.1 h in the oral tablet group, a difference that was not statistically significant. Conclusion. The results showed that the 25-mu g vaginal tablets of misoprostol were as effective and safe for cervical ripening and labor induction as the dose-equivalent fraction of 200-mu g oral tablets.

Camponeses Brazil's Peasant Movement in Historical Perspective (1946-2004)

Comparison of the histories of three leading peasant organizations in the Pontal do Paranapanema region of Brazil-the Partido Comunista do Brasil (PCB) from 1945 to 1964, the Confederacao Nacional de Trabalhadores na Agricultura (CONTAG) from 1964 to 1984, and the Movimento dos Trabalhadores Rurais Sem-Terra (MST) from 1984 to 2004-suggests that continuity is as important as change in understanding Brazilian peasant movements. The MST has been considered a "new social movement" in that it has eschewed partisan politics, incorporated families as members rather than just male heads of household, had a national scope and a participatory decision-making structure, and been attuned to the international struggle over globalization. Placing it in historical perspective makes it clear, however, that this is not the first time that militants have organized around the concept of peasants as a political identity; that while the representation of peasants in the leadership of contemporary rural labor organizations may be greater than in the past, earlier peasant leaders also struggled on behalf of their class; that earlier peasant organizations had, if not a national presence, a substantial presence in the agricultural states of the time; and that attempts at international organization to unite peasant struggles around the globe are not entirely new. This is not to deny the innovative features of contemporary movements but to suggest that the investigation of past achievements will contribute to a fuller appreciation of these movements' conditions and prospects.

Division of labor in Ectatomma edentatum (Hymenoptera, Formicidae)

The behavioral division of labor between queens and workers of E. edentatum was investigated under laboratory conditions. Each behavioral category of both castes was described by direct observation of the ants in the colonies. The spatial position and the behavior of each individual were recorded. A colony ethogram was constructed to determine comparatively the behavioral repertory of the 2 castes. Most of the members of the colonies, including the queens, occupied the 2nd chamber, which also contained the immature stages. Forty-two behavioral categories were recorded for the workers, and 28 for the queens. The comparison of the behavioral repertory of the 2 castes revealed that ovipositing a fecundated egg is an exclusive behavior of the queens, while the workers showed 15 exclusive behaviors. Queens were never seen foraging out of the nest. Twelve behaviors were common for both castes. Polygynic colonies have only 1 female with full-developed ovaries, which is the main egg layer of the group, a feature defining the social organization of colonies of E. edentatum as a functional monogyny.

Division of labor in pachycondyla striata Fr. Smith, 1858 (Hymenoptera: Formicidae: Ponerinae)

Four colonies of the ant Pachycondyla striata were used to analyze the specie behavioral repertoire. Forty-six behavioral acts were recorded in laboratory. Here, we present the record the division of labor between the castes and the temporal polyethism of monomorphic workers. The queens carried out many of the behavioral traits recorded in this work however; they performed them less frequently compared to the worker. The workers activity involved chasing and feeding on fresh insects and usingthem to nourish larvae besides laying eggs in the C-posture, an activity also performed by queens, which is similar to that of wasps of the subfamily Stenogastrinae. The young workers were involved in activities of brood care, sexuate care, and nest maintenance, and the older workers were involved in defense, exploration, and foraging. © 2012 Adolfo da Silva-Melo and Edilberto Giannotti.
