Fish populations are sensitive to environmental impact resulting from many factors, as an introduction of exotic species, industrial or residual waste, oil spills, pesticides or other agents that can directly affect the ecology and species survival. Astyanax altiparanae is pelagic and active swimmer specie and can have serious implications on its way of life as changes in muscle structure of fish may occur since the presence of pollutants in the water. In this study we analyze the alterations in Muscle and collagen fibers of the pectoral muscles and pollutants exposed flows contained in water with biodegradable detergents, and water coming from the Blue Lake, River clear-SP (2o24'39"S, 47o33'39"E) diluted. Effects of these exposures were analyzed during the period of seven and thirty days. Compared with acclimatized fish (Astyanax altiparanae) with pure water from an artesian well, the muscle fibers morphology and collagen concentration on them have changed due to the exposure to urban pollutants and biodegradable detergents.

Indiscriminate disposal of residues of domestic and/or industrial origin in aquatic ecosystems resulting from urban activities causes concern about their effects on the fauna. Substances absorbed by animals, such as those cited above, are metabolized by the liver, as it is the main target organ of several pollutants and also exercises basic vital functions in the organism. For this reason the liver is used as the main and most reliable biomarker in environmental studies. Thus the objective of the present study was to identify hepatic alterations resulting from exposure to water contaminated by a few commercial brands of biodegradable detergents and their effects when present together with several other contaminants found in nature. For such, a solution of 1 ppm of biodegradable detergents and water from an urban lake were tested on two widely distributed native Brazilian fish (Astyanax altiparanae and Prochilodus lineatus). Several alterations were found on the liver, including cytoplasm vacuolization, nuclear displacement, macrophage recruitment and reduced liver glycogen, showing a degenerative process in the liver of the fish, due to the action of contaminants.

A literature search of articles from 2002-2019 was performed using Medline, Embase, Cochrane, LILACS, IBECS, CRD, and Epistemonikos databases, to analyze the effects of Cognitive-Behavioral Therapy (CBT) in the treatment of fibromyalgia. Twenty-seven articles were selected in which CBT was performed exclusively by specialist physicians, associated or not with conventional pharmacological treatment and/or physical exercise. In most articles, CBT worked with self-knowledge and cognitive restructuring, attempting to reduce pain perception, and it showed a general improvement in daily activities by decreasing patient’s limitations, such as morning stiffness. The literature showed significant correlations of CBT in pain processing over time. When CBT was compared to conventional pharmacological therapy, a certain superiority of CBT could be observed concerning the quality of life, catastrophizing, and acceptance of pain. However, when they were simultaneously applied, this improvement in quality of life was not observed.
