Inquérito sorológico para a rubéola em professoras do município de São Paulo, Brasil

The sera of 415 female schoolteachers aged 20 to 35 years and over, from the city of São Paulo, Brazil, were tested for rubella hemagglutination-inhibiting antibodies. Antibodies to rubella virus were found in 67.9%. Of these, 59.5% had titers ranging from 1:8 to 1:32 and 8.4% had titers of 1:64 and higher. No significant differences were observed between age-groups. Four of 35 sera with titers of 1:64 and higher showed reduction in the hemagglutination-inhibiting antibody titer after treatment with 2 ME, a sulphydryl-reduction compound wich breaks down IgM immunoglobulins. Some comments are presented on the necessity of developing programs of routine tests for the continuing assessment of the susceptibility of schoolteachers to rubella infection and vaccination, provided adequate precautions are followed.Estudou-se a distribuição etária de anticorpos inibidores da hemaglutinação para o vírus da rubéola em 415 soros de professoras de 27 parques infantis e 75 escolas municipais, da rede municipal de ensino de São Paulo. Deste total, 67,9% dos soros apresentavam títulos iguais ou superiores a 8, considerados como indicativos da presença de imunidade. Não se observaram diferenças significativas entre os diversos grupos etários estudados, relativamente à distribuição dos porcentuais de positividade. A distribuição porcentual dos títulos de anticorpos inibidores da hemaglutinação foi de 32,1% para títulos menores do que 8, 29,3% para título 8, 18,1% para título 16, 12,1% para título 32 e 8,4% para títulos iguais ou superiores a 64. De 35 soros com títulos iguais ou superiores a 64, após tratamento com 2-mercapto-etanol, 4 sofreram uma redução significativa do título. São feitas algumas considerações sobre os riscos de infecção a que estão sujeitas as professoras e sugere-se, entre os requisitos exigidos para a admissão das mesmas nas redes oficiais e particulares de ensino, o diagnóstico sorológico da rubéola, bem como o estabelecimento de um serviço de vacinação, devidamente controlado

Resposta sorológica de adultos à vacinação contra a rubéola

The effect of Wistar RA 27/3 live attenuated rubella virus vaccine, given subcutaneously, was evaluated in 30 susceptible female schoolteachers aged 20 to 35 years and over, from the city of São Paulo, Brazil. The serum samples, to be tested for hemagglutination-inhibiting (HI) and complement fixing (CF) antibodies, were collected 10, 30, 90 and 180 days after vaccination. Of the 30 susceptible adults who received the Wistar RA 27/3 vaccine, 96,6% showed seroconversion in the HI and CF tests. No unusual reactions occured.Foi estudada a resposta sorológica à vacinação contra a rubéola, por via subcutânea, com a cepa vacinal viva atenuada Wistar RA 27/3, num grupo de 30 professoras da rede municipal de ensino de São Paulo. Foram escolhidos, como participantes do grupo, indivíduos destituídos de imunidade contra a rubéola, tendo as dosagens de anticorpos inibidores da hemaglutinação e fixadores do complemento sido feitas em amostras de soro colhidas 10, 30, 90 e 180 dias após a vacinação. Tanto nas provas de inibição da hemaglutinação, como fixação do complemento, observou-se uma soro-conversão de 96,6%. Não se observaram quaisquer relações vacinais no grupo em estudo

Identificação por contraimunoeletroforese de rotavirus em casos de diarréia infantil

The faecal samples of 162 children with acute diarrhea were tested by counterimmunoelectrophoresis in order to detect rotaviruses. In 72.7%, 77.7% and 66.6% of samples from children of different age groups, varying from 6 to 8 months to 1 year or older, a positive result was found.Os resultados obtidos na identificação de rotavirus, usando a técnica da contraimunoeletroforese, com 162 amostras de feses de crianças com quadros diarréicos agudos, mostram uma distribuição percentual de positividade de 72,7%, 77,7% e 66,6% em diferentes grupos etários de 6 a 8 meses até um ano de idade

A reação de fixação do complemento na identificação de rotavírus humano

Após a eliminação da anticomplementaridade, foi utilizada a reação de fixação do complemento na identificação de rotavírus em 134 amostras de fezes de crianças até um ano de idade, com quadros diarréicos agudos. A percentagem total de positividade foi de 28,7% com percentagens mais elevadas de casos positivos nos grupos etários de 6 meses a 1 ano de idade.After eliminating the anticomplementarity of the fecal extracts, complement fixation was used to detect human rotavirus in the stools of 35 (28.7%) out of 122 one-to twelve-month-old children with acute gastroenteritis. Infection was nigher in the 6-to 12-month-old children

Patterns of sports sponsorship by gambling, alcohol and food companies: an Internet survey

BACKGROUND: Sports sponsorship is a significant marketing tool. As such, it can promote products that pose risks to health (eg, high fat and high sugar foods) or it can promote health-supporting products (eg, sporting equipment and services). However, there is a lack of data on the proportion of sponsorship associated with "unhealthy" and "healthy" products and no methodology for systematically assessing it. This research aimed to explore this proportion with an Internet survey of sports sponsorship in the New Zealand setting. METHODS: A search methodology was developed to identify Internet-based evidence of sports sponsorship at the national level and at the regional and club level in one specific region (Wellington). The top eight sports for 5-17-year-olds were selected and products and services of sponsors were classified in terms of potential public health impact (using a conservative approach). RESULTS: Sponsorship of these popular sports was common at the national, regional and club levels (640 sponsors listed on 107 websites overall). Sports sponsorship associated with sponsors' products classified as "unhealthy" (eg, food high in fat and sugar, gambling and alcohol) were over twice as common as sponsorship associated with sponsors' products classified as "healthy" (32.7% (95% CI = 29.1, 36.5) versus 15.5% (95% CI = 12.8, 18.6) respectively). "Gambling" was the most common specific type of sponsorship (18.8%) followed by alcohol (11.3%). There were significantly more "alcohol" sponsors for rugby, compared to all the other sports collectively (rate ratio (RR) = 2.47; 95% CI = 1.60, 3.79), and for top male sports compared to female (RR = 1.83; 95% CI = 1.05, 3.18). Also there was significantly more "unhealthy food" sponsorship for touch rugby and for "junior" teams/clubs compared to other sports collectively (RR = 6.54; 95% CI = 2.07, 20.69; and RR = 14.72, 95% CI = 6.22, 34.8; respectively). A validation study gave an inter-rater reliability for number of sponsors of 95% (n = 87 sponsors), and an inter-rater reliability of classification and categorisation of 100%. CONCLUSION: This study found that the sponsorship of popular sports for young people is dominated by "unhealthy" sponsorship (ie, predominantly gambling, alcohol and unhealthy food) relative to "healthy" sponsorship. Governments may need to consider regulations that limit unhealthy sponsorship and/or adopt alternative funding mechanisms for supporting popular sports
