Impai red balance is one of several factors that increase an elderly's susceptibility to falls. Balance assessment can be performed using postural tests and plantar cutaneous sensitivity tests. Aim: To assess balance disorders and loss of plantar cutaneous sensitivity in the elderly and look for association between these alterations. Materials and Methods: A descriptive cross-sectional study involving 45 elderly submitted to the Berg Balance Scale (BBS) and the plantar sensitivity test with nylon monofilament. We used chi-square and Fisher's exact tests, and ROC curves were created in order to study the sensitivity and specificity of BBS. Results: Two and 4 individuals showed balance and cutaneous sensation disorders, respectively. There was a significant association between the complaint of impaired balance and loss of skin sensitivity (p = 0.047), and there was a reasonable agreement (Kappa: 0.6457) between the BBS and the sensorial test. A significant association was also found among 6 of the 14 BBS tasks and the sensitivity test. Conclusion: Most of the elderly living independently in the community showed normal balance and plantar cutaneous sensation. When impaired, these functions appeared associated in a way that if the tests are performed together, the accuracy of the evaluation of the balance increases.
Abstract:Marinheiros is the largest island of the estuarine archipelago of Patos lagoon and is considered an area of biological relevance in the coastal region of the extreme south of Brazil. Aiming to contribute to the knowledge on the biodiversity of this important area, we conducted an ichthyofaunistic inventory in the limnic environments of the island. Twenty-seven field trips were performed between April 2015 and May 2017. A total of 12 sites representative of habitats of an intermittent shallow lagoon, intermittent pools and a perennial artificial channel were sampled. Sampling of 2,436 specimens revealed the occurrence of 30 species, including the non-native piscivorous Acestrorhynchus pantaneiro. Characiformes was the most diverse order (18 species), followed by Cichliformes (four species) and Cyprinodontiformes (three species). Characiformes was also the most numerically abundant order (77%) followed by Cichliformes (17.6%) and Cyprinodontiformes (5.1%). The species richness recorded in Marinheiros Island is is comparable to the richness observed for lotic systems of southernmost Brazilian coastal plain. The fish assemblage is composed mainly of species of limnic habits whereas few taxa of estuarine-marine-limnic and estuarine-limnic habits were recorded. In view of the presence of allochtonous A. pantaneiro and its potential to impact native species, monitoring is recommended to the ichthyofauna of Marinheiros Island and the other estuarine islands, as well as peninsular systems connected to Patos lagoon estuary.

Com o objetivo de contribuir para o conhecimento sobre a biodiversidade desta importante área, realizamos um inventário ictiofaunístico nos ambientes limnicos da ilha. Vinte e sete visitas foram realizadas entre abril de 2015 e maio de 2017. Um total de 12 locais representativos dos habitats de uma lagoa rasa intermitente, poções intermitentes e um canal artificial perene foram amostrados. A amostragem de 2.436 espécimes revelou a ocorrência de 30 espécies, incluindo o piscívoro não-nativo Acestrorhynchus pantaneiro. Characiformes foi a ordem mais diversa (18 espécies), seguido por Cichliformes (quatro espécies) e Cyprinodontiformes (três espécies). Characiformes foi também a ordem mais numericamente abundante (77%), seguida po Cichliformes (17,6%) e Cyprinodontiformes (5,1%). A riqueza de espécies registrada na Ilha dos Marinheiros é comparável à riqueza observada para sistemas lóticos da planície costeira do extremo sul do Brasil. A assembleia de peixes é composta principalmente por espécies de hábitos límnicos, enquanto que poucos taxa de hábitos estuarino-marinho-límnico e estuarino-límnico foram registrados. Em vista da presença do alóctono A. pantaneiro e ...
A Restinga da Lagoa dos Patos (RLP) compreende São José do Norte, Tavares, Mostardas e Palmares do Sul. O objetivo deste trabalho foi reconhecer as paisagens ameaçadas com base nas formas de uso e ocupação do espaço. Foi utilizado um mapa base de classes de paisagem que correspondem ao uso e ocupação do solo e os descritores métricos foram aplicados aos níveis de classe e da paisagem. As classes antrópicas ocupam mais de dois terços da área total da restinga (68, 6%). A classe antrópico rural é a matriz da paisagem. São José do Norte está mais susceptível aos impactos ocasionados pelas atividades associadas ao setor do petróleo e gás natural. Tavares, com a presença do Parque Nacional da Lagoa do Peixe (PNLP) possui a maior integridade das áreas naturais. Embora Mostardas abrigue parte do PNLP muitos de seus remanescentes naturais podem ser perdidos devido à expansão do cultivo de soja e da silvicultura. Em Palmares do Sul a expansão dos cultivos de arroz e de soja configuram a principal ameaça. O crescimento econômico sem planejamento territorial é uma ameaça à conservação. Portanto, o zoneamento ecológico econômico costeiro e a criação de unidades de conservação são necessárias ao desenvolvimento sustentável.ABSTRACT The Restinga da Lagoa dos Patos (RLP) includes São José do Norte, Tavares, Mostardas and Palmares do Sul municipalities. The goal of this study was the recognition of the threatened landscapes of the RLP, based on type of use and occupation of space. A base map of landscape’s classes was used. The classes correspond to the use and occupation of land. Metrical descriptors were applied to the levels class and landscape. Anthropogenic classes occupy more than two-thirds of the total area of RLP (68.6%). The rural anthropic class is the matrix of the landscape. São José do Norte is more susceptible to the impacts caused by activities from the oil use and gas sector. Tavares, due to the presence of the Parque Nacional da Lagoa do Peixe (PNLP), is the municipality with greater integrity of natural areas. Although Mostardas shelters a part of the PNLP many of its natural remnants may be lost due to agricultural expansion from soybean farming and silviculture. In Palmares do Sul the expansion of rice and soybean plantations figures the major threat. Economic growth without territorial planning threats conservation. Thus, economic ecological zoning and the creation of further environmental protection areas are important actions for sustainable development.Keywords: Restinga da Lagoa dos Patos; landscape ecology; metrics.
