RESUMO
PURPOSE: Cancer chemotherapy can induce fatigue in about 20% to 30% of patients. So far, there is very little information as to the predictors of chemotherapy-induced fatigue (CIF). We evaluated potential predictors of CIF in a sample of patients with cancer with several types of solid tumors scheduled to receive chemotherapy according to institutional protocols. METHODS: Before their first and second chemotherapy cycles, patients answered to the Brief Fatigue Inventory (BFI), Chalder, Mini Nutritional Assessment (MNA), Stress thermometer, and HADS questionnaires as well as provided blood samples for inflammatory markers. RESULTS: We evaluated 52 patients, 37 (71%) were female and mean age was 53 years. The most common tumors were breast cancer 21 (40%) and gastrointestinal tumors 12 (23%). Although 14 (25.2%) patients had an increase in their fatigue BFI scores equal or above 3 points from baseline, we observed no significant overall differences between BFI scores before and after chemotherapy. The only 2 factors associated with an increase of 3 points in the BFI scores after chemotherapy were race and higher baseline BFI levels. By multivariate analysis, overall BFI and Chalder scores after chemotherapy also correlated significantly with their respective baseline scores before treatment. HADS scores before treatment correlated with overall BFI scores postchemotherapy, whereas MNA scores before chemotherapy and female sex correlated with higher Chalder scores after treatment. CONCLUSION: We conclude that fatigue induced by chemotherapy is common and consistently associated with higher fatigue scores before treatment. Screening for fatigue before chemotherapy may help to identify patients who are prone to develop CIF.

OBJECTIVE: To evaluate the evolution of injuries of the supraspinatus muscle by immunohistochemistry (IHC) and anatomopathological analysis in animal model (Wistar rats). METHODS: Twenty-five Wistar rats were submitted to complete injury of the supraspinatus tendon, then subsequently sacrificed in groups of five animals at the following periods: immediately after the injury, 24h after the injury, 48h after, 30 days after and three months after the injury. All groups underwent histological and IHC analysis. RESULTS: Regarding vascular proliferation and inflammatory infiltrate, we found a statistically significant difference between groups 1(control group) and 2 (24h after injury). IHC analysis showed that expression of vascular endothelial growth factor (VEGF) showed a statistically significant difference between groups 1 and 2, and collagen type 1 (Col-1) evaluation presented a statistically significant difference between groups 1 and 4. CONCLUSION: We observed changes in the extracellular matrix components compatible with remodeling and healing. Remodeling is more intense 24h after injury. However, VEGF and Col-1 are substantially increased at 24h and 30 days after the injury, respectively. Level of Evidence I, Experimental Study.

Obesity is a chronic and multifactorial disease, whose prevalence is increasing in many countries. Pharmaceutical strategies for the treatment of obesity include drugs that regulate food intake, thermogenesis, fat absorption, and fat metabolism. Fenproporex is the second most commonly consumed amphetamine-based anorectic worldwide; this drug is rapidly converted in vivo into amphetamine, which is associated with neurotoxicity. In this context, the present study evaluated DNA damage parameters in the peripheral blood of young and adult rats submitted to an acute administration and chronic administration of fenproporex. In the acute administration, both young and adult rats received a single injection of fenproporex (6.25, 12.5 or 25 mg/kg i.p.) or vehicle. In the chronic administration, both young and adult rats received one daily injection of fenproporex (6.25, 12.5, or 25 mg/kg i.p.) or Tween for 14 days. 2 h after the last injection, the rats were killed by decapitation and their peripheral blood removed for evaluation of DNA damage parameters by alkaline comet assay. Our study showed that acute administration of fenproporex in young and adult rats presented higher levels of damage index and frequency in the DNA. However, chronic administration of fenproporex in young and adult rats did not alter the levels of DNA damage in both parameters of comet assay. The present findings showed that acute administration of fenproporex promoted damage in DNA, in both young and adult rats. Our results are consistent with other reports which showed that other amphetamine-derived drugs also caused DNA damage. We suggest that the activation of an efficient DNA repair mechanism may occur after chronic exposition to fenproporex. Our results are consistent with other reports that showed some amphetamine-derived drugs also caused DNA damage.

Maple syrup urine disease is an inborn error of metabolism caused by a severe deficiency of the branched chain alpha-ketoacid dehydrogenase complex. Neurological dysfunction is a common finding in patients with maple syrup urine disease. However, the mechanisms underlying the neuropathology of brain damage in this disorder are poorly understood. In this study, we investigated whether acute or chronic administration of a branched chain amino acid pool (leucine, isoleucine and valine) causes transient DNA damage, as determined by the alkaline comet assay, in the brain and blood of rats during development and whether antioxidant treatment prevented the alterations induced by branched chain amino acids. Our results showed that the acute administration of branched chain amino acids increased the DNA damage frequency and damage index in the hippocampus. However, the chronic administration of branched chain amino acids increased the DNA damage frequency and damage index in both the hippocampus and the striatum, and the antioxidant treatment was able to prevent DNA damage in the hippocampus and striatum. The present study demonstrated that metabolite accumulation in MSUD induces DNA damage in the hippocampus and striatum and that it may be implicated in the neuropathology observed in the affected patients. We demonstrated that the effect of antioxidant treatment (N-acetylcysteine plus deferoxamine) prevented DNA damage, suggesting the involvement of oxidative stress in DNA damage.

Porto Alegre e comparar a gravidade da doença entre pacientes com um ou mais agentes virais.Métodos: um estudo transversal, realizado entre setembro de 2009 e setembro de 2010, incluiu lactentes de até 12 meses de idade com diagnóstico de bronquiolite viral aguda, que estavam internados nas unidades pediátricas do Hospital São Lucas da PUCRS e haviam iniciado com sintomas de vias aéreas inferiores até 72 horas antes da inclusão. A pesquisa de vírus respiratórios foi realizada em amostras de secreção nasofaríngea, por imunofluorescência direta.Resultados: foram coletadas 71 amostras de um total de 73 pacientes, cuja média de idade foi de 3,3 meses. Do total das amostras coletadas, 61,97% (44/71) foram positivas para vírus. Destas, 70,46% (31/44) foram positivas para apenas um vírus e 29,54% (13/44) para dois ou mais vírus. O vírus sincicial respiratório foi o mais comum (86,36%), seguido pelo influenza (27,27%). Utilizando os desfechos tempo de internação e tempo de uso de oxigênio, não foi observada associação entre presença de coinfecção e gravidade da bronquiolite.Conclusões: o estudo demonstrou uma positividade geral elevada para vírus, com a predominância do vírus sincicial respiratório. Foi demonstrado também um alto índice de coinfecção viral. Não houve efeito adicional, pela presença de mais de um tipo de vírus, na gravidade da bronquiolite. Não se pode excluir a possibilidade de que a combinação com outros vírus, não identificados neste estudo, possa influenciar a gravidade da bronquiolite viral aguda.
Aims: To evaluate the epidemiologic characteristics and to compare the seriousness of the infection between one or more than one viral agents in infants hospitalized with acute viral bronchiolitis.Methods: A cross-sectional study conducted between September 2009 and September 2010 included infants up to 12 months of age diagnosed with acute viral bronchiolitis, who were admitted to the pediatric units of the Hospital São Lucas da PUCRS and had started with lower airways symptoms to 72 hours before inclusion. Testing for respiratory viruses was performed on nasopharyngeal specimens by direct immunofluorescence.Results: Seventy one samples were collected from a total of 73 patients, whose mean age was 3.3 months. Of the total samples collected, 61,97% (44/71) were positive for virus. Of these, 70,46% (31/44) were positive for one virus and 29,54% (13/44) for two or more viruses. Respiratory syncytial virus was the most common (86,36%), followed by parainfluenza (27,27%). Using the outcomes length of hospital stay and time of use of oxygen, there was no association between the presence of coinfection and severity of bronchiolitis.Conclusions: The study demonstrated a high overall positivity for viruses, with the predominance of respiratory syncytial virus. A high rate of viral coinfection was also showed. There was no additional effect of the presence of more than one type of virus on the severity of bronchiolitis. We can not exclude the possibility that the combination with other viruses, unidentified in this study, may influence the severity of acute viral bronchiolitis.
