This study aimed to evaluate the effectiveness of a bovine brucellosis vaccination program in Rio Grande do Sul, with prevalence as the indicator, and to identify risk factors for the disease. The state was divided into seven regions. For each region, a predetermined number of properties were randomly sampled, in which a pre-established number of randomly selected females aged over 24 months were tested. The serodiagnosis protocol consisted of a screening test using buffered acidified antigen, followed by a confirmatory test using 2-mercaptoethanol. An epidemiological questionnaire was utilized to identify possible risk factors associated with bovine brucellosis. In the state of Rio Grande do Sul, the prevalence of infected herds was found to be 3.54% [2.49-4.88], and the prevalence of infected animals was 0.98% [0.57-1.57]. In assessments of specific regions, the infected herd prevalence ranged from 0.66% to 3.09%, and among the animals, from 0.06% to 2.03%. In herds comprising 15 or more cows, beef type and pasture sharing emerged as risk factors for bovine brucellosis in the state. The epidemiological status of bovine brucellosis in Rio Grande do Sul has remained unchanged since 2004, even though adequate vaccination coverage has been recorded since 2009. Thus, the state should continue its vaccination program, with emphasis on the quality of the process and on encouraging the use of non-antibody inducing vaccines. In addition, the state must make a greater effort to educate producers on the importance of testing for brucellosis in breeding animals before introducing them onto their properties, and on the importance of avoiding shared grazing among herds whose health conditions are unknown.

A cross-sectional study on the epidemiological situation of bovine brucellosis was carried out in the state of Tocantins to evaluate the effectiveness of its vaccination program. The state was divided into five regions, and a predetermined number of farms was randomly selected in each one. Females aged 24 months or older were randomly selected in each farm and diagnosed with brucellosis by serial serology (AAT and 2-ME). A total of 6,846 animals from 756 farms were examined. The prevalence of seropositive herds in the state was 6.42% [CI95%: 4.76-8.62], and the prevalence of seropositive animals was 2.21% [CI95%: 1.05-4.01]. The prevalence of seropositive herds was homogeneously distributed among regions. The 2002/2003 study estimated the prevalence of seropositive herds in the state to be 21.22% [CI95%: 19.33-23.11]. In conclusion, the vaccination program implemented in Tocantins, reaching vaccination coverage above 70% as of 2010, significantly reduced the prevalence of seropositive herds. Thus, continuing the vaccination program in the state is recommended, preferably increasing the quality of the processes involved, from commercialization to inoculation in animals, since immunization remains the most effective means to reduce the prevalence of brucellosis. In addition, animal replacement remains a major risk factor for bovine brucellosis in Tocantins since 20022003; therefore, the state must implement a strong health education program explaining to farmers the importance of testing animals for brucellosis before introducing them into their herds.

A study was conducted to determine the epidemiological status of bovine tuberculosis in the state of Rio Grande do Sul. The state was divided in seven regions, and in each of them, a pre-established number of farms was randomly sampled. In each farm, cows with age equal to or greater than 24 months were selected at random and submitted to the comparative cervical tuberculin test. The animals whose tests were inconclusive were retested with the same diagnostic procedure within a minimum interval of 60 days. In all, 9,895 animals from 1,067 farms were tested. An epidemiological questionnaire was applied in the farms in order to identify risk factors associated with bovine tuberculosis. The prevalence of infected herds in the state was 2.8% [1.8; 4.0] and that of infected animals was 0.7% [0.4; 1.0]. There was a trend towards a concentration of infected herds in the northern part of the state, with a predominance of dairy and mixed herds. The risk factors associated with the condition of infected herds were being a dairy herd (OR = 2.90 [1.40; 6.13]) and herds with 16 or more cows (OR = 2.61 [1.20; 5.49]). Thus, the best strategy to be adopted by the state is the implementation of surveillance systems to detect and remediate the infected herds, preferably incorporating elements of risk-based surveillance. In addition, the state must carry out a solid action of health education so that the producers test animals for bovine tuberculosis before introducing them in their herds.

Abstract: The objective of this work was to determine the genetic progress of grain quality attributes of flooded irrigated rice (Oryza sativa) cultivars in the state of Rio Grande do Sul, Brazil, between 1972 and 2016. The genetic estimates followed an approach based on the comparative analysis of 25 cultivars released by Embrapa’s breeding program over this period. The experiment was implemented in four producing regions of the state of Rio Grande do Sul: Sul, Campanha, Planície Costeira Interna, and Planície Costeira Externa. The following significant genetic gains were observed: 0.20% per year, for percentage of whole grains after processing; -1.38% per year, for percentage of chalky kernels and white-core grains; -0.77% per year, for total chalky area; -0.08% per year, for total whiteness; and -0.82% per year, for non-vitreous grain whiteness. Most cultivars released have high amylose content and a low gelatinization temperature. Therefore, the breeding program presented significant annual genetic progresses between 1972 and 2016 for the main attributes of grain quality, and made cultivars available according to the national demand for grain quality in the several segments of the rice production industry.

A study was conducted to verify that the State of Santa Catarina has maintained a low prevalence of bovine brucellosis, which would allow the state to move forward with implementing strategies for disease eradication. The state was divided into five regions. In each region, a predetermined number of randomly selected properties was sampled. In each property, blood samples were collected from randomly selected cows with ages equal to or greater than 24 months. Sera from the animals were submitted to a serial testing protocol, with screening by the buffered acidified antigen test and confirmation by the 2-mercaptoethanol test. In each property, a questionnaire was used to identify the risk factors associated with the disease. In the state, the prevalence rate of infected herds was 0.912% [0.297 - 2.11] and infected animals was 1.21% [0.09 - 4.97]. Relative to the earlier study in 2002, there was no difference. The risk factors associated with the condition of a herd infected with brucellosis were as follows: herd size ? 12 cows (OR = 7.47 [2.14 - 34.34]) and the presence of flooded areas (OR = 5.68 [1.62 - 26.13]). In view of the low prevalence, it is recommended that the state proceed with the implementation of eradication strategies that are based on a surveillance system structured to detect and eliminate infected herds, and supported by an effective compensation fund for the replacement of seropositive animals. Additionally, the State should make a significant effort to educate and supervise producers to ensure the testing of breeding animals for brucellosis before introducing them into their properties.

Abstract Objectives: to investigate factors associated with the route of birth delivery in a hospital extending public and private healthcare services, in the Northeast region in the State of Rio Grande do Sul. Methods: a cross-sectional study with 676 postpartum women, conducted from January to May 2017. The data were collected from the hospital records and women were interviewed shortly after childbirth in the maternity. Data analysis was performed by associating the Pearson’s chi-square and the Poisson regression tests with robust variance. Results: the prevalence of cesarean sections was 58.7%, that is, 41.7% in public health-care and 83.9% in private healthcare. The main reason for having a cesarean section was having had a previous one (PR=5.69; CI95%=3.64 - 8.90; p<0.001), followed by having source of childbirth financing (PR=1.54; CI95%=1.27 - 1.87; p<0.001), having source of prenatal care financing (PR=1.48; CI95%=1.22 - 1.79; p<0.001), the childbirth and prenatal care professional (PR=1.46; CI95%=1.28 - 1.66; p<0.001) and the prenatal care professional (PR=1.43; CI95%=1.07 - 1.90; p=0.016). Conclusions: the high cesarean section rates identified in this study were mainly associated with previous cesarean section. The findings suggest a change in the current childbirth care model in the city, characterized as highly medicalized, focused on the physician and on hospital care.
