La aplicación de la regionalización al comercio de carnes: ¿A qué obedece la reticencia?

Actualmente, el comercio mundial de cárnicos registra cambios sustanciales como consecuencia de la propagación de enfermedades animales transfronterizas, que han puesto en evidencia la práctica de embargos absolutos a países infectados, transgrediendo así el principio de regionalización. Este principio permite que parte del territorio de un país pueda declararse libre de una determinada enfermedad, aunque se hayan producidos brotes en otras regiones, evitándose así la suspensión de todas las exportaciones. Su aplicación consiste en el reconocimiento formal de una zona libre de enfermedad o plaga.  En el presente artículo se dan a conocer algunos de los conflictos provocados por la reticencia a la aplicación del principio de regionalización en el caso de tres grandes enfermedades transfronterizas que han afectado el comercio de carnes en los últimos años: la enfermedad de las "vacas locas", la fiebre aftosa y la gripe aviar. En el texto  se analiza la posición de algunos mercados consumidores y los desafíos que los principales países exportadores han tenido que enfrentar ante los embargos comerciales.

Níveis de mercúrio, prolactina e interleucina 10 em mulheres em idade reprodutiva e puérperas dos municípios de Itaituba e Ananindeua, Pará

Ao mercúrio tem sido atribuída a capacidade de interferir nos sistemas orgânicos imunológico e hormonal, além dos sistemas nervoso e renal frequentemente atingidos por esse agente tóxico. Mulheres em idade fértil ou grávidas constituem um grupo vulnerável a esses efeitos, em relação a si mesmas e seus conceptos. Foi avaliada a exposição ao mercúrio (Hg) e os níveis de prolactina (PRL) e interleucina-10 (IL-10) em 144 mulheres (no pós-parto e cerca de um ano depois) de Itaituba, área sob impacto ambiental do mercúrio e em mulheres de municípios da área metropolitana de Belém, sobretudo Ananindeua, área sem impacto conhecido do mercúrio (156 puérperas e 156 não puérperas). As análises de mercúrio total (Hg-t) em sangue foram feitas por Espectrometria de Absorção Atômica por Vapor Frio. As análises séricas de PRL foram feitas por Ensaio Imunoenzimático com detecção final em fluorescência e as determinações de IL-10 foram realizadas por Ensaio Imunoenzimático de Fase Sólida. Dados demográficos e epidemiológicos foram obtidos através de questionário semi-estruturado. As puérperas de Itaituba apresentaram média de Hg-t, PRL e IL-10 de 13,93 μg/l, 276,20 ng/ml e 39,54 pg/ml, respectivamente. Nas puérperas de Ananindeua as respectivas médias foram 3,67 μg/l, 337,70 ng/ml e 4,90 pg/ml. As mulheres não puérperas de Itaituba apresentaram média de Hg-t de 12,68 μg/l, média de PRL de 30,75 ng/ml e média de IL-10 de 14,20 pg/ml. As médias de Hg-t, PRL e IL-10 das mulheres de Ananindeua foram 2,73 μg/l, 17,07 ng/ml e 1,49 pg/ml, respectivamente. Os níveis de Hg-t, PRL e IL-10 foram maiores em Itaituba (p<0,0001), exceto em relação à PRL das puérperas, maior em Ananindeua. Os níveis semelhantes de Hg-t nas duas avaliações das mulheres de Itaituba (p=0,7056) e a correlação moderada sugerem continuidade da exposição (r=0,4736, p<0,0001). A principal variável preditora dos níveis de mercúrio foi o consumo de peixe nos modelos de regressão múltipla linear e logística. A paridade e os níveis de IL-10 apresentaram associação positiva com a PRL nas puérperas de Itaituba e o peso do recém-nascido e a IL-10, associação positiva com a PRL em puérperas de Ananindeua. A IL-10 apresentou associação negativa com a PRL nas mulheres não puérperas de Itaituba (p=0,0270) e positiva nas mulheres de Ananindeua (p=0,0266). Os níveis de Hg-t estavam associados negativamente com a PRL nas puérperas (p=0,0460) e positivamente com o trabalho em garimpo (p=0,0173) (este também importante para as não puérperas) em Itaituba, segundo os modelos logísticos. A IL-10 esteve associada positivamente à morbidade recente nas puérperas de Itaituba (p=0,0210), negativamente ao consumo de bebida alcoólica (p=0,0178) e positivamente ao trabalho em garimpo nas mulheres não puérperas (p=0,0199). A exposição crônica ao Hg das mulheres de Itaituba, a diferença nos níveis dos fatores imunoendócrinos avaliados em relação às mulheres não expostas e a associação com variáveis epidemiológicas relevantes, sugerem a possibilidade de impactos da exposição no perfil imunoendócrino das mulheres de Itaituba, chamando atenção para a importância da vigilância da saúde dessa população e o possível uso de bioindicadores como a PRL em sua avaliação.

Avaliação ultrassonográfica dos efeitos da acupuntura na involução uterina em cadelas

The aim of this study was to evaluate, by means of ultrasound exam, acupuncture effects on uterine involution during the postpartum period in bitches with electroacupuncture. The phenomenon of eutocic uterine involution was studied in 16 bitches, randomly divided into two groups of eight animals each. Group 1 (G1) was treated with electric stimulation (electroacupuncture) of the needle at the points SP6, L3, Bai Hui, TB1, B23, B26, and group 2 (G2), the control group, received treatment in Sham points (placebo points), also with electrical stimuli. The monitoring of the phenomenon of uterine involution was performed by ultrasonography on days 0 (partum), 1, 3, 7 and 14 postpartum. We used SAS statistical analysis method, in order to compare the groups. The results of ultrasound examinations (mean and standard deviations in cm) for the period of observation were as follows: G1: 0.30 ± 0.01 (P), 2.08 ± 0.21 (LU), 4.13 ± 0.23 (DU) and G2: 0.31 ± 0.01 (P) 1.82 ± 0.09 (LU), 3.92 ± 0.11 (DU). We concluded that electroacupuncture affected uterine tone (lasting and uniform at the end of treatment). Electroacupuncture produces a positive tone in the uterus, aiding at the prevention of puerperal diseases.

Pregnancy Monitoring of In Vitro Produced Embryos in Buffaloes

In the present study, pregnancies obtained from 115 in vitro produced embryos were monitored by ultrasonography on days 30 and 60 after embryo transfer (ET), and at calving. Additionally, the health of newborns and recipients were also evaluated. On day 30 after ET, positive pregnancy was diagnosed in 50 animals (43.5%). A total of 8 fetal mortalities (16.0%) were verified from 30 days until calving, in which 2 occurred from 30 to 60 days after ET (4.0%), and 6 occurred from 60 days until calving (12.0%). In this last period of pregnancy, 3 pregnancy losses were due to abortion, and the other 3 were stillbirth. One additional animal was eliminated from the study, remaining 41 pregnancies. From these 41 pregnancies, a total of 20 female calves (48.8%) and 21 male calves (51.2%) were born. Pregnancies from female and male calves had a mean length of 309.8 and 310.9 days, respectively (range 300 to 328 days, and 297 to 320 days, respectively). Weight at calving was a mean of 31.4 and 33.8 kg for female and male calves, respectively. All calving occurred without intervention and dystocia was not observed in any case. No large offspring syndrome, hydramnios, hydroallantois, or umbilical cord anomalies were observed in calves. Delivery was normal in all recipients, and no puerperal infections, or retained placenta occurred. Suckling assistance was not necessary in any newborn. All genetic pedigree was confirmed later by DNA tests.

Sanidade Uterina Pós Parto: Aspectos Imunológicos e Terapêuticos

Function of the uterus is often compromised in cattle by bacterial contamination of the uterine lumen after parturition. Pathogenic bacteria often persist, causing uterine disease, a major cause of infertility in cattle. Knowledge of the immunological aspects of the uterus involved in maintaining reproductive healthiness is fundamental to the study of uterine infections that affect the uterus postpartum. Polymorphonuclear leukocytes have an important role because they are the first line of defense against colonization of bacteria in utero (Hammon and Goff, 2006). The establishment of uterine infection depends in parts of endocrine environment, particularly progesterone, which suppresses the immune system (Lewis, 2003). In the puerperium may occur uterine disorders, such as retained placenta, puerperal metritis, clinical and subclinical endometritis and pyometra, this review was proposed a study of the immunology involved in uterine health and a better understanding of uterine disorders, using the model of Sheldon et al. al, (2006) for classification of diseases, and a study of best treatment options and discussion about its functionality, because a lot of controversy among authors about choosing a treatment and another and between treated and untreated

Frequência e perfil de gestantes com toxoplasmose em uma unidade de saúde de Matão - SP

Congenital toxoplasmosis is a serious public health case, for it causes irreversible damage to the embryo/fetus, which may cause its death. The identification and the care to pregnant women with suspect acute toxoplasmosis (IgM+) is performed in prenatal monitoring. This study aimed to measure the incidence and know the profile of positive pregnant women for toxoplasmosis in a Basic Health Unit (BHU) in Matão - SP, between the years 2011 to 2013. This is a retrospective descriptive study, from the medical records of pregnant women attended. The project was approved by the Municipal Departament of Health and BHU was chosen along the Municipal Epidemiological Surveillance. From 2011 to 2013, 189 women began prenatal care in the unit, an annual median of 71(±26.91), of which 17 (8.99%) were positive for the serological test indicative of acute phase (IgM+). The distribution over the trial period was: four cases in 2011, twelve cases in 2012 and one in 2013. Pregnant women IgM positive for toxoplasmosis attend by BHU were: age 24(±5.47) years; color: equally distributed among white, black and brown; as the number of pregnancies: multiparous (2±0.97), most of them with a cesarean delivery as obstetric history and possessed no other risk factors associated with pregnancy (94.12%); gave entrance at BHU with 13.65(±7.35) weeks of gestation and had a median of 5(±2.36) consultation on their prenatal care. The examination for toxoplasmosis was requested as recommended by the Health Ministry (HM) and the medication prescribed was Roxamicina® - spiramycin, as soon as the test results (IgM+) arrived. Of the 17 pregnant women, only 10 completed the pre-natal at BHU - attendance at the postpartum consult (58.8%). Of these, the deliveries were vaginal (55.55%), made preterm with 36.5 weeks of gestation at the Municipal Hospital. The babies were born alive (100%) with the weight of 2.68(±0.77) Kg and required special care hospital scope. From the ...

Ações educativas para o controle de vetores da dengue e leishmaniose visceral

Results of educative actions on the control of vectors for dengue and leishmaniasis were evaluated by using an online semi-present course directed to teachers from Fundamental I Education level in Araçatuba-SP. 40 teachers from municipal schools located on geographical areas of town with higher occurrence of dengue and leishmaniasis cases, attended to the course, which consisted in a conceptual part directed to specific subjects such as vector borne and zoonotic diseases, responsible ownership of pets and health education and a practical phase, directed to execution and application of educative projects in the target schools. Data about the teacher’s specific knowledge, before and after the attendance to the course, were submitted to the Wilcoxon test with a 5% of significant level. The application of practical educative projects was evaluated by multiplicative actions involving target public. Tests showed statistically significant increase in the knowledge about the studied diseases (p<0.0001) after the course, especially on questions related to etiological agent, clinical symptoms on man and animals and prevention. Activities of knowledge multiplication envolved teachers and students which detected the problems and promoted education actions in their neighborhood as stage performing, group cleaning activities and elaboration and distribution of folders during a student pared. In conclusion, educative actions direct to the control of diseases vectors using a semi-present course, provides new knowledge to the teachers, impelling them to motivate their students to adopt vectors control measures and environmental cares and to sensitive the community to collaborate with control diseases.
