Complementary data on four methods for sampling free-living ticks in the Brazilian Pantanal.

In this study, four methods for sampling free-living ticks that are used in ecological and human tick-bite risk studies were evaluated. Cloth dragging, carbon dioxide traps and visual searches and inspection of plant litter on the ground were used in field and forest areas within the Brazilian Pantanal. Among the three tick species collected, Amblyomma sculptum predominated, followed by Amblyomma parvum and Amblyomma ovale. Dragging, a cheap and simple technique, yielded the highest numbers of ticks, particularly nymphs. The visual search detected a high number of adult ticks and provided information on tick questing height. Even though laborious, plant litter examination showed that large numbers of ticks may use this stratum. Carbon dioxide (CO2) traps are expensive and difficult to handle, but they are highly efficient for adult ticks, especially A. parvum. These data indicate that one method alone is incapable of providing a representative sample of the tick fauna in a particular area and that multiple techniques should be used for tick population studies

CENTRO DE PARTO NORMAL COMO ESTRATÉGIA DE INCENTIVO AO PARTO NORMAL: ESTUDO DESCRITIVO

Recientemente se verificó un esfuerzo gubernamental para reducir las tasas de cesariana en el sector público y cualificar la asistencia al parto normal. Así, se crearon los Centros de Parto Normal (CPN) destinados al acompañamiento de nacimientos fisiológicos, a cargo de enfermeras obstétricas. Este estudio descriptivo tuvo como objetivo caracterizar a las parturientas en cuanto a la edad materna, historia obstétrica, condiciones del parto y del recién-nacido en un CPN, en la ciudad de São Paulo. Se utilizaron datos secundarios de registros de nacimientos atendidos por enfermeras obstétricas y se analizaron 1.860 registros de partos ocurridos en julio y agosto de 2001. Los resultados indican: edad media de 23,7 años; 44,4% de nulíparas; 79,0% de partos normales; peso medio de los recién-nacidos de 3.174g; Apgar ≥7 en el primer y quinto minutos en 93,7% y 99,1% de los recién nacidos, respectivamente. Se concluyó que la atención al parto hecha por enfermeras obstétricas es importante para valorar la fisiología del parto y nacimiento, con indicadores obstétricos y neonatales de calidad.Tem-se verificado um esforço governamental para reduzir as taxas de cesariana no setor público e qualificar a assistência ao parto normal.

Big sugar in southern Africa : rural development and the perverted potential of sugar/ethanol exports

This paper asks how investment in large-scale sugar cane production has contributed, and will contribute, to rural development in southern Africa. Taking a case study of the South African company Illovo in Zambia, the argument is made that the potential for greater tax revenue, domestic competition, access to resources and wealth distribution from sugar/ethanol production have all been perverted and with relatively little payoff in wage labour opportunities in return. If the benefits of agro-exports cannot be so easily assumed, then the prospective 'balance sheet' of biofuels needs to be re-examined. In this light, the paper advocates smaller-scale agrarian initiatives

Brazilian obstetrician-gynecologists and abortion: a survey of knowledge, opinions and practices

BACKGROUND: Abortion laws are extremely restrictive in Brazil. The knowledge, opinions of abortion laws, and abortion practices of obstetrician-gynecologists can have a significant impact on women's access to safe abortion. METHODS: We conducted a mail-in survey with a 10% random sample of obstetrician-gynecologists affiliated with the Brazilian Federation of Obstetricians and Gynecologists. We documented participants' experiences performing abortion under a range of legal and illegal circumstances, and asked about which abortion techniques they had experience with. We used chi-square tests and crude logistic regression models to determine which sociodemographic, knowledge-related, or practice-related variables were associated with physician opinion. RESULTS: Of the 1,500 questionnaires that we mailed out, we received responses from 572 (38%). Less than half (48%) of the respondents reported accurate knowledge about abortion law and 77% thought that the law should be more liberal. One-third of respondents reported having previous experience performing an abortion, and very few of these physicians reported having experience with manual vacuum aspiration (MVA) or with misoprostol with either mifepristone or methotrexate. Physicians that favored liberalization of the law were more likely to have correct knowledge about abortion law, and to be in favor of public funding for abortion services. CONCLUSION: Brazilian obstetrician-gynecologists need more information on abortion laws and on safe, effective abortion procedures

Reflexões sobre deambulação e posição materna no trabalho de parto e parto Reflexiones sobre deambulación y posición materna en el trabajo de parto y parto Reflection on ambulation and maternal position during labor and delivery

Este artigo apresenta uma reflexão sobre os fatores determinantes que levaram à mudança da posição da mulher de vertical para horizontal no processo de parturição. A institucionalização do processo de parir e nascer promoveu uma série de mudanças no assistir à mulher e à família. Muitas das práticas que preservavam o respeito à autonomia e aos valores culturais deram lugar a outros que valorizam a tecnologia, a medicalização e a intervenção. Tais mudanças não efetivaram significativa redução na mortalidade materna e neonatal, pelo contrário, promoveram a desumanização da assistência. Um novo olhar sobre o efeito da deambulação e da posição durante o trabalho de parto e parto está sendo incentivado e está dando oportunidade de evidenciar uma série de vantagens e benefícios para mãe e filho.<br>Este artículo presenta una reflexión sobre los factores determinantes que llevaran al cambio de la posición de la mujer de vertical para horizontal en el proceso de parturiación.

The institutionalization of the labor and birth process that promoted a lot of changes in the woman and family assistance. Many practicals preserved the autonomy respect and the cultural values that give place to other ones that valued the technology, the medicalization and the intervention. Such changes didn't make possible a significant reduction in the mother mortality and neonatal, in other way, they promoted the lack of humanization in the assistance. A new look on the ambulation effect and the position during labor and delivery is been encouraged and giving opportunity to became evident a variety of vantages and benefits to the mother and child
