ABSTRACT
Background. The need for healthcare in paediatric patients is often due to respiratory diseases, acute diarrhoea and viral fever, which suggests a limited need for the use of antibiotics.Objectives. To identify the determinants of antibiotic prescription in hospitalised paediatric patients in Mozambique.Methods. A cross-sectional study was conducted between January and June 2015. A total of 454 medical prescriptions and clinical records of children aged 0 - 14 years from Hospital Central de Maputo (HCM) and Hospital Geral de Mavalane (HGM) were analysed.Results. Antibiotics were used in 97.6% of the patients, with no significant differences (p>0.05) in the prescription rates of the hospitals. The most commonly used antibiotics were beta-lactams (57.3%), aminoglycosides (28.3%) and co-trimoxazole(9.4%). Antibiotics were prescribed in all cases of bronchopneumonia, fever, sepsis and acute gastroenteritis. For malaria and undefined diagnoses, antibiotics were prescribed 97.8% and 99.3% of cases, respectively. It was clear that most severe clinical conditions (odds ratio (OR) 9.06; 1.13 - 12.14) and age <5 years (OR 5.47;1.54 - 7.60) were treated with antibiotics.Conclusion. The prescription of antibiotics for paediatric patients at both HCM and HGM was largely influenced by patients' clinical condition and age. It showed that physicians used an empirical approach, in the absence of laboratory tests, often leading to unnecessary antibiotic treatments with negative causative effects. Physicians should be encouraged to use an evidence-based approach for managing the cases correctly

Abstract Aquatic macroinvertebrate fauna is a relevant component of limnic continental aquatic ecosystems, playing an important role in several processes with relevant biocomplexity. The present study characterized the benthic macroinvertebrate fauna found in three hydric bodies in the Sinos river drainage basin regarding community structure. Sample was collected from January to December 2013 in three locations in the basin: the city of Caraá (29 °45’45.5”S/50°19’37.3”W), the city of Rolante (29°38’34.4”S/50°32’33.2”W) and the city of Igrejinha (29°36’10.84”S/50°48’49.3”W). Abiotic components (pH, dissolved oxygen and temperature) were registered and collected samples were identified up to family type. Average annual pH, dissolved oxygen and temperature were similar in all locations. A total of 26,170 samples were collected. Class Insecta (Arthropods) represented 85.5% of total sample. Platyhelmintes, Mollusca and Annelida samples were also registered. A total of 57 families were identified for the drainage basin and estimators (Chao-1, Chao-2 and jackknife 2) estimated richness varying from 60 to 72 families.
Resumo A fauna de macroinvertebrados aquáticos é um relevante componente dos ecossistemas aquáticos límnicos continentais, atuando em vários processos de importante biocomplexidade. O presente estudo caracterizou a fauna de macroinvertebrados bentônicos em três corpos hídricos da Bacia Hidrográfica do Rio dos Sinos, em relação a estrutura da comunidade. Amostragens foram realizadas de janeiro a dezembro de 2013 em três locais na bacia: Município de Caraá (29°45’45,5”S/50°19’37,3”W), Município de Rolante(29°38’34,4”S/50°32’33,2”W) e Município de Igrejinha(29°36’10,84”S/50°48’49,3”W). Variáveis abióticas (pH, oxigênio dissolvido e temperatura) foram registradas e os exemplares coletados identificados até família. As médias anuais de pH, oxigênio dissolvido e temperatura foram similares em todos os pontos. Um total de 26.170 exemplares foi amostrado. A Classe Insecta (Arthropoda) representou 85,5% do total. Platyhelmintes, Mollusca e Annelida também foram registrados. Foram determinadas 57 famílias para a bacia hidrográfica e os estimadores (Chao-1, Chao-2 e jackknife 2) projetaram uma riqueza variando de 60 a 72.

Foi utilizado novo dispositivo para amostragem de macroinvertebrados bênticos de água doce num segmento do curso inferior arenoso de um rio brasileiro subtropical (Rio Caí, Triunfo, RS) e de seu pequeno tributário, Arroio Bom Jardim. Neste estudo, a efetividade do amostrador PET foi testada em locais diferentes do rio e do arroio e ao longo das quatro estações do ano, entre 2001-2002. Foram realizadas comparações por PCA e ANOVA, ambos empregando um procedimento "bootstrap" com base em matrizes de similaridade. O amostrador PET é confiável para detecção de diferenças sazonais e espaciais de riqueza, abundância total de organismos e diversidade de Shannon no rio e no arroio, sendo, portanto, recomendável para o monitoramento de comunidades de macroinvertebrados nesse sistema.
