Estudio de inmunogenicidad para dos vacunas recombinantes contra hepatitis B
This study compares the immunogenicity (seroconversion, seroprotection and hiperesponse) produced by two hepatitis B recombinant vaccines (Engerix- B Belge and Cuban). For this purpose two sketches were used (012 and 016 months). The anti-HBs quantification was performed by using Abbott and Organon methods in order to compare its results. In the study 257 volunteers were distributed in four groups to the hapazard (two vaccines and two sketches). Results: the Abbott and Organon methods did not show any statistically significant difference. The Cuban vaccine shows greater immunogenous response for two doses and 012 sketch. There are no differences between sketch 012 and 016 with the Cuban vaccine. The scheme 016 did not show statistically significant difference for the Engerix-B Belge vaccine. The last mentioned vaccine showed to be better with the 016 scheme.Este estudio compara la inmunogenicidad (seroconversión, seroprotección e Hiperrespuesta), producida por dos vacunas recombinantes contra la hepatitis B (Engerix-B de Bélgica y Cubana), en dos esquemas (012 y 016 meses), empleando los métodos de cuantificación para Anti-HBsAg (Abbott y Organón), los cuales fueron también comparados. En el estudio participaron 257 voluntarios, divididos al azar en 4 grupos (dos vacunas, dos esquemas). Resultados: los dos métodos de Abbon y Organon, no presentan diferencias estadísticas significativas. La vacuna cubana muestra una mayor respuesta inmunogénica para dos dosis de vacuna y para el esquema 012. No hay diferencia entre los esquemas 012 y 016 y en el esquema 016 no se ven diferencias estadísticamente significativas con la vacuna Engerix-B. En esta Última el esquema 016 muestra mejores resultados que el 012

Falciparum malaria molecular drug resistance in the Democratic Republic of Congo: a systematic review
peer reviewedBackground: Malaria cases were estimated to 207 million in 2013. One of the problems of malaria control is the
emergence and spread of Plasmodium falciparum strains that become resistant to almost all drugs available. Monitoring
drug resistance is essential for early detection and subsequent prevention of the spread of drug resistance by
timely changes of treatment policy. This review was performed to gather all data available on P. falciparum molecular
resistance in DR Congo, as baseline for future assessments.
Methods: The search for this review was undertaken using the electronic databases PubMed and Google Scholar
using the terms “malaria”, “Congo”, “resistance”, “molecular”, “antimalarial”, “efficacy”. Articles were classified based on year
of collecting, year of publication, sample size and characteristics, molecular markers analysed and polymorphisms
detected.
Results: Thirteen articles were included and five genes have been analysed in these studies: pfcrt, pfdhps, pfdhfr,
pfmdr1 and K13-propeller. The majority of studies included were not representative of the whole country.
Conclusion: This systematic review demonstrates the lack of molecular resistance studies in DRC. Only 13 studies
were identified in almost 15 years. The MOH must implement a national surveillance system for monitoring malaria
drug resistance and this surveillance should be conducted frequently and country-representative

Analysis of Bacteria, Parasites, and Heavy Metals in Lettuce (Lactuca sativa) and Rocket Salad (Eruca sativa L.) Irrigated with Treated Effluent from a Biological Wastewater Treatment Plant
This study aimed to evaluate the viability of using treated residuary water from the Biological Wastewater Treatment Plant of Ribeiro Preto to grow vegetables, through the characterization and quantification of parasites, coliforms, and heavy metals. Three equal cultivation areas were prepared. The first was irrigated with treated/chlorinated (0.2 mg L(-1)) wastewater, the second one with treated wastewater without chlorination, and the third site with potable water, which was the control group. The presence of Hymenolepis nana, Enterobius vermicularis, nematode larvae, and Entamoeba coli was verified in lettuce (Lactuca sativa) samples. Although nematode larvae were observed in rocket salad (Eruca sativa L.), no significant differences were found between the number of parasites and type of irrigation water used. No significant differences were found between the number of fecal coliforms in vegetables and the different types of irrigation. However, the vegetables irrigated with treated effluent without chlorination showed higher levels of fecal coliforms. The risk of pathogens is reduced with bleach addition to the treated effluent at 0.2 mg/L. Concentration of heavy metals in vegetables does not mean significant risks to human health, according with the parameters recommended by the World Health Organization.State of Sao Paulo Research Foundation (FAPESP)[06/59920-8]State of Sao Paulo Research Foundation (FAPESP)[06/55788-8]AMBIENT, Environmental Services of Ribeirao Preto S
