Variations in lipid profile have been observed in sickle cell disease (SCD) and understanding their relationship with disease severity is crucial. This study aimed to investigate the association of polymorphisms of the CETP gene and laboratory markers of disease severity with lipid profile in a pediatric population with SCD. Biochemical and anthropometric analyses and CETP and alpha-thalassemia genotyping were performed. The study included 133 children and adolescents with sickle cell anemia (SCA) or hemoglobin SC disease (SCC), in steady-state. The SCA and no hydroxyurea (no HU) groups had higher values of ApoB, total cholesterol, low-density lipoprotein cholesterol (LDL-C), and non-high-density lipoprotein cholesterol (non-HDL-C) compared to the SCC and HU groups. However, there were no significant differences in ApoA1 and HDL-C levels between the groups based on genotype. Furthermore, the groups with altered levels of ApoA1, HDL-C, and the triglyceride/HDL ratio exhibited lower hemoglobin (Hb) levels and higher white blood cell counts. Hb level was associated to HDL-C levels. Analysis of CETP gene variants showed that the minor alleles of rs3764261 (C>A), rs247616 (C>T), and rs183130 (C>T), as well as the TTA haplotype, are explanatory variables for HDL-C levels. These findings suggested that dyslipidemia in SCD, specifically related to HDL-C levels, may be influenced by individual genetic background. Additionally, further investigation is needed to determine if clinical manifestations are impacted by CETP gene variants.

Seizures are a disorder caused by structural brain lesions, life-threatening metabolic derangements, or drug toxicity. The present study describes the behavior related to proconvulsant activity induced by thiocolchicoside (TCC) in rats and investigates the electrocorticographic patterns of this behavior and the effectiveness of classic antiepileptic drugs used to control these seizures. Forty-nine adult male Wistar rats were used and divided into two phases of our experimental design: 1) evaluation of seizure-related behavior and electrocorticographic patterns induced by TCC and 2) evaluation of the efficacy of classical antiepileptic drugs to control the proconvulsive activity caused by TCC. Our results showed that TCC induced tonic-clonic seizures that caused changes in electrocorticographic readings, characteristic of convulsive activity, with average amplitude greater than that induced by pentylenetetrazole. Treatment with anticonvulsants, especially diazepam, reduced the electrocorticographic outbreaks induced by TCC. The results suggested that TCC caused seizures with increased power in brain oscillations up to 40 Hz and that diazepam may partially reverse the effects.

We aimed to evaluate whether the administration of riboflavin to septic animals reduces inflammation, oxidative stress, organ dysfunction, and mortality. C57BL/6 mice, 6-8 weeks old, were allocated to the study group (polymicrobial sepsis induced by cecal ligation and puncture (CLP) + antibiotic + iv riboflavin), control (CLP + antibiotic + iv saline), or naïve (non-operated controls). Serum concentrations of alanine aminotransferase (ALT), creatine kinase-MB (CK-MB), urea, and creatinine, and markers of inflammation [interleukin (IL)-6, tumor necrosis factor (TNF)-α, keratinocyte-derived chemokine (KC), and macrophage inflammatory protein (MIP)-2)], and oxidative stress (malondialdehyde (MDA) were measured 12 h after the experiment. Animal survival rates were calculated after 7 days. Means between groups were compared using linear regression models adjusted under the Bayesian approach. No significant difference was observed between control and study groups in serum concentrations of IL-6 (95% credible interval) (-0.35 to 0.44), TNF-α (-15.7 to 99.1), KC (-0.13 to 0.05), MIP-2 (-0.84 to 0.06), MDA (-1.25 to 2.53), or ALT (-6.6 to 11.5). Serum concentrations of CK-MB (-145.1 to -30.1), urea (-114.7 to -15.1), and creatinine (-1.14 to -0.01) were higher in the study group. Survival was similar in both groups (P=0.8). Therefore, the use of riboflavin in mice undergoing sepsis induced by CLP did not reduce inflammation, oxidative stress, organ dysfunction, or mortality compared with placebo.

Abstract The search for new therapeutic strategies for leishmaniasis treatment is essential due to the side effects of available drugs and the increasing incidence of resistance to them. Marine sponges use chemical compounds as a defense mechanism, and several of them present interesting pharmacological properties. The aim of this study was to evaluate the in vitro activity of the aqueous extract of the marine sponge Dercitus (Stoeba) latex against Leishmania amazonensis. MIC and toxicity against mammal cells were evaluated through broth microdilution assays. Transmission electron microscopy analysis was performed to assess possible effects on L. amazonensis ultrastructure. Arginase and proteolytic activities were measured by spectrometric methodologies. The extract of Dercitus (Stoeba) latex displayed antileishmanial activity and moderate toxicity against peritonial macrophages. Ultrastructural changes were observed after the growth of L. amazonensis promastigotes in the presence of the extract at 150 µg.ml-1 (IC50), mainly on acidocalcysomes. The extract was able to inhibit the activity of arginase and serine proteases. This study shows that Dercitus (Stoeba) latex aqueous extract may be a novel potential source of protozoa protease inhibitors and drugs that are less toxic to be used in the treatment of L. amazonensis infections.

RESUMO Um cachorro-vinagre (Speothos venaticus) apresentou um nódulo cutâneo pequeno na região perianal. Histologicamente havia neoplasia cutânea de células redondas e ulcerada, constituída por mastócitos bem diferenciados, com abundantes grânulos citoplasmáticos metacromáticos na coloração de Giemsa e infiltrado eosinofílico difuso. A imuno-histoquímica demonstrou que 30% das células neoplásicas eram positivas para a proteína Kit no citoplasma e na membrana celular. As células foram negativas para MAC e CD3. Menos de 10% das células neoplásicas foram positivas para Ki67. Durante a necropsia, foram identificados outros tumores primários, como adenoma intestinal, adenoma cortical da adrenal e tumor de células intersticiais do testículo.
ABSTRACT A senile male captive bush dog (Speothos venaticus) presented a small perianal cutaneous nodule. Histologically, there was an ulcerated round cell tumor composed of well differentiated mast cells with abundant intracytoplasmic purple Giemsa-positive granules, with a diffuse eosinophilic infiltrate. Immunohistochemistry revealed that 30% of the neoplastic cells were positive for Kit in the cytoplasm and cell membrane, and all neoplastic cells were negative for MAC and CD3. Less than 10% of the neoplastic cells were positive for Ki67. At necropsy other primary tumors were identified in this animal, including an intestinal adenoma, an adrenal cortex adenoma and a testicular interstitial cell tumor.

RESUMO: O objetivo do estudo foi realizar a avaliação ultrassonográfica de órgãos do terço médio e caudal da cavidade celomática de serpentes hígidas da família Boidae. Para isto, foram avaliadas 15 serpentes adultas de cinco espécies: Boa constrictor amarali, Boa constrictor constrictor, Eunectes murinus, Epicrates assisi e Epicrates crassus. Os animais foram contidos fisicamente para a realização do exame. Após aplicação de gel acústico sobre as escamas, o transdutor foi posicionado no plano frontal da cavidade celomática. Foram utilizados transdutores microconvexo e linear em 10MHz. O exame ultrassonográfico foi conduzido no sentido craniocaudal, com cortes longitudinais e transversais para avaliar sintopia, ecogenicidade e ecotextura dos órgãos. O fígado se apresentou bilobulado, hiperecoico, ecotextura homogênea, cápsula hiperecoica, com lobo hepático medindo 1,15±0,64cm de largura, e presença de uma veia central hepática, medindo 0,44±0,21cm de diâmetro. A vesícula biliar foi caracterizada como uma estrutura anecoica de paredes ecogênicas e dimensões de 2,91±1,18cm x 1,38±0,84cm(comprimento x largura). O estômago apresentou-se com o aspecto pregueado e linear, ecogênico, com paredes hipoecoicas medindo 0,3±0,07cm de largura. O esplenopâncreasse apresentou como uma estrutura circular e ecogênica, ecotextura homogênea e medindo de 1,18±0,62cm de largura e 1,56±0,88cm de comprimento. Os rins se caracterizaram por estruturas alongadas, lobuladas, hipoecoicas, cápsula ecogênica e uma linha central ecogênica, medindo 1,05±0,7cm de largura. Os testículos foram caracterizados por estruturas fusiformes, hipoecoicas, ecotextura homogênea, medindo 2,31±0,79cm de comprimento e 0,6±0,23cm de largura. Foram visualizados folículos ovarianos em diferentes estágios, de 0,67±0,39cm de largura e 0,73±0,38cm de comprimento. Não foram encontradas diferenças entre espécies de sintopia, ecogenicidade e ecotextura dos órgãos da cavidade celomática. O exame ultrassonográfico demonstrou-se uma técnica segura, não invasiva e eficiente para caracterização dos órgãos da cavidade celomática de serpentes.
ABSTRACT: The aim of this study was the ultrasonographic evaluation of the organs in the middle third and caudal coelomic cavity of healthy snakes in the Boidae family. For such, 15 adult snakes from five species were evaluated: Boa constrictor amarali, Boa constrictor constrictor, Eunectes murinus, Epicrates assisi and Epicrates crassus. The animals were physically restrained for examination. After the application of acoustic gel over the scales the transducer was positioned in the frontal plane of the coelomic cavity. Microconvex and linear transducers at 10MHz were used. The ultrasound examination was conducted in the craniocaudal direction, with longitudinal and transversal sections to assess syntropy, echogenicity and echotexture of the organs. The liver was bilobulated, hyperechoic, homogeneous echotexture, hyperechoic capsule, with a hepatic lobe measuring 1.15±0.64cm wide, and the presence of a central hepatic vein, measuring 0.44±0.21cm in diameter. The gallbladder was characterized as an anechoic structure with echogenic walls and dimensions of 2.91±1.18cm x 1.38±0.84cm (length x width). The stomach showed a pleated and linear texture, echogenic, with hypoechoic walls measuring 0.3±0.07cm wide. The splenopancreas was a circular and echogenic structure, homogeneous echotexture and measuring 1.18±0.62cm in width and 1.56±0.88cm in length. The kidneys were characterized by elongated, lobulated, hypoechoic structures, an echogenic capsule and an echogenic central line, measuring 1.05±0.7cm in width. The testis were characterized by fusiform, hypoechoic structures, homogeneous echotexture, measuring 2.31±0.79cm in length and 0.6±0.23cm in width. Ovarian follicles were seen in different stages, 0.67±0.39cm wide and 0.73±0.38cm long. No differences were found between species of syntropy, echogenicity and echotexture of the organs of the coelomic cavity. The ultrasound examination proved to be a safe, non-invasive and efficient technique for characterizing the organs of the coelomic cavity of snakes.

Since the outbreak of severe acute respiratory coronavirus 2 (SARS-CoV-2), the coronavirus disease 2019 has had a wide range of effects on human health. This paper summarizes the data related to the effects of the SARS-CoV-2 infection on human reproduction. Both the male and female reproductive tract express high levels of receptors and proteins needed for viral cell entry. There is presently no evidence that gametes are affected by the infection. Male fertility may be temporarily reduced due to inflammatory responses following infection. The endometrium is highly susceptible to SARS-CoV-2 cell entry; however, it remains unclear whether this could alter receptivity and embryo implantation. Menstrual cycle changes were reported in women who experienced severe infection; however, they tended to be reversible. For couples undergoing assisted reproduction treatment, the pandemic led to a significant psychological burden, with changes in lifestyle that could directly affect the success of the treatment. Human reproduction societies recommend screening all patients prior to cycle initiation and avoiding treatment of women with severe comorbidities until the pandemic is under control. Finally, for pregnant women, it is expected that the infection is more severe in women in the third trimester and in those with comorbidities. Those who are symptomatic for SARS-CoV-2 are more likely to have increased rates of prematurity and intrapartum fetal distress than those who are asymptomatic. Vertical transmission cannot be completely ruled out, but neonatal infection rates are low. Vaccination appears to be safe and is indicated for use in pregnant and lactating women because the benefits outweigh the risks.

RESUMO O objetivo do estudo foi avaliar os efeitos do óleo essencial (OE) de tomilho nos parâmetros ruminais, na digestibilidade e no balanço de nitrogênio em borregos alimentados com elevado teor de concentrado. Vinte borregos providos de cânulas ruminais foram blocados de acordo com o peso corporal (PC=64,0±2,1kg) e receberam um dos tratamentos: 25mg de monensina/kg de matéria seca (MS; MON) ou doses de OE de tomilho (1,25; 2,50 ou 3,75g/kg de MS). A dieta foi composta por 90% de concentrado. A composição do OE de tomilho foi principalmente timol (46,6% da MS) e p-cimeno (38,9% da MS). A ingestão e a digestibilidade dos nutrientes foram semelhantes entre os tratamentos. A inclusão de 3,75g de OE de tomilho tendeu (P=0,07) a aumentar o butirato em relação aos tratamentos MON e 1,25OE. Os borregos alimentados com 1,25g de OE tenderam (P=0,07) a apresentar menor pH ruminal no 14º dia comparado a MON. No entanto, os tratamentos não afetaram a relação acetato:propionato, concentração total de ácidos graxos de cadeia curta e retenção de nitrogênio. Os resultados sugerem que a adição de OE de tomilho em dietas com elevado teor de concentrado pode ser uma alternativa à monensina como aditivo alimentar para cordeiros em confinamento.
ABSTRACT This trial aimed to evaluate the effects of thyme essential oils (EO) on rumen parameters, nutrient digestibility and nitrogen balance in wethers fed with high-concentrate diet. Twenty rumen-cannulated wethers were blocked according to body weight (BW= 64.0±2.1kg), and received one of the following treatments: 25mg of monensin/kg of dry matter (DM; MON) or doses of thyme EO (1.25, 2.50 or 3.75g/kg of DM). The diet was composed of 90% concentrate. Thyme EO was composed mainly by thymol (46.6% of DM) and p-cymene (38.9% of DM). The nutrient intake and apparent digestibility were similar among treatments. The inclusion of 3.75g of thyme EO tended (P= 0.07) to increase butyrate compared to MON and 1.25OE and wethers fed with 1.25g of thyme EO tended (P= 0.07) to decrease ruminal pH on the 14th day compared to MON. The treatments did not affect acetate:propionate ratio, total short chain fatty acids (SCFA) and nitrogen retention. Results from this study suggest that adding thyme EO to high-concentrate diets may be used as an alternative to monensin as feed additive in feedlot lambs.

Objetivou-se neste estudo avaliar a eficiência da aplicação e eficácia de controle de aguapé (Eichhornia crassipes) com o uso do herbicida diquat veiculado com dois volumes de aplicação. associado a três classes de gotas. Foram conduzidos três experimentos: no primeiro avaliou-se a eficiência da aplicação; no segundo, a eficácia de controle; e, no terceiro, o espectro de gotas, conduzidos em delineamento inteiramente casualizado, com cinco, quatro e seis repetições, respectivamente. Os tratamentos foram dispostos em esquema fatorial 2 x 3, com dois volumes de aplicação (100 e 200 L ha-1) e três classes de gotas (fina, extremamente grossa e ultragrossa) para o primeiro e o segundo experimento, e o terceiro foi constituído por duas concentrações do herbicida diquat na calda (2 e 4 g de i.a. L-1) e por três classes de gotas (fina, extremamente grossa e ultragrossa). A eficiência da aplicação foi determinada pela cobertura por gotas, deposição de calda e ingrediente ativo do herbicida (diquat). Já a eficácia foi quantificada pelo controle e pela porcentagem de plantas com rebrote até 50 dias após a aplicação. Foi analisado o espectro das gotas produzidas por cada modelo de pontas utilizado para obter as classes de gotas. De acordo com os parâmetros analisados, o uso das classes de gotas extremamente grossa e ultragrossa pode proporcionar maior segurança na aplicação do herbicida diquat em ambiente aquático, associado à deposição do ativo e cobertura suficiente para controle de E. crassipes com ambos os volumes de aplicação.
The objective of this study was to evaluate the efficiency of application and the efficacy of control of water hyacinth (Eichhornia crassipes) with the use of the diquat herbicide done with two application volumes associated to three droplets classes. Three experiments were conducted; in the first, the application efficiency was evaluated; in the second, the control efficiency and; in the third, the droplet spectrum. They were conducted in a completely randomized design with five, four and six replicates, respectively. The treatments were arranged in a 2 x 3 factorial design, with two application volumes (100 and 200 L ha-1) and three droplets classes (fine, extremely coarse and ultra-coarse) to the first and second experiment and the third comprised two diquat concentrations in spray solution (2 and 4 g i.a. L-1) and three droplets classes (fine, extremely coarse and ultra-coarse). The application efficiency was determined by the coverage by droplets, spray deposition and active ingredient of the herbicide (diquat). The efficacy was measured by the control and the percentage of plants with regrowth at 50 days after application. The spectrum of droplets produced per each nozzle model used to obtain the droplets classes were analyzed. According to the parameters analyzed, using the droplets classes extremely thick and ultra thick can provide greater certainty in the application of diquat in the aquatic environment associated with the deposition of the active and sufficient coverage to control Eichhornia crassipes with both application volumes

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

A Bradypus variegatus habita florestas da América do Sul e alimenta-se de folhas, ramos e brotos de várias plantas. Em decorrência de sua dieta, bem como da escassez de literatura sobre aspectos morfológicos dos Xenarthras, avaliaram-se cinco línguas de Bradypus variegatus, que foram a óbito por causas naturais, provenientes do Museu Paraense Emílio Goeldi e doados ao Laboratório de Pesquisa Morfológica Animal (LaPMA) da UFRA, a fim de se elucidarem os diferentes tipos de papilas e a interface epitélio-tecido conjuntivo. Macroscopicamente, as línguas apresentaram formato alongado, ápice arredondado, corpo, raiz, sulco mediano do ápice à raiz e duas papilas valadas. A mucosa da língua revelou epitélio de revestimento pavimentoso estratificado queratinizado, enquanto a face ventral era delgada e lisa, desprovida de qualquer tipo de papila. Já a face dorsal apresentou-se irregular, com a presença de três tipos papilares: papilas filiformes, fungiformes e valadas. As papilas filiformes encontradas eram do tipo simples, com base circular, distribuídas irregularmente, com maior concentração e desenvolvimento no ápice e no corpo da língua. A papila fungiforme mostrou-se com superfície praticamente lisa e de formato irregular, com a presença de poros gustativos. Estas foram encontradas por toda a superfície dorsal, com maior concentração na parte rostral do ápice. Foram observadas apenas duas papilas valadas, dispostas na região da raiz da língua, com corpo rodeado por sulcos profundos e vários botões gustativos. As línguas de Bradypus variegatus apresentaram papilas linguais similares às descritas para outras espécies de Xenarthras e mamíferos selvagens.
The Bradypusvariegatus inhabits the forests of South America and feeds from leaves, branches and sprouts from different plants. Due to its diet and the lack of literature on the morphological aspect of Xenarthras, five Bradypusvariegatus tongues from animals which died from natural causes were evaluated, and they came from Pará State Museum Emílio Goeldi and were donated to the Laboratory of Animal Morphological Research (LaPMA) from UFRA, for revealing the different types of papillae and epithelial-connective tissue. Macroscopically, the tongues presented elongated shape, rounded apex, body, root, median sulcus in the root's apex, and two vallate papillae. The mucous membrane of the tongue revealed a keratinized stratified pavement epithelium, while the ventral surface of the tongue was thin and smooth, not provided with any type of papillae. However, the dorsal surface of the tongue was irregular with the presence of three types of papillae: filiform, fungiform and vallate papillae. The filiform papillae found were of a simple type, presenting a rounded base, irregularly distributed with a larger concentration and development on the tongue's apex and body. The fungiform papilla showed a practically smooth surface with irregular format, with the presence of gustatory pores; these were found all over the dorsal surface, with larger concentration at the rostral part of the apex. Only two vallate papillae were observed disposed in the root of the tongue, surrounded by a deep groove, and revealing several taste buds. The tongues from Bradypusvariegatus presented gustatory papillae similar to the ones described for other Xenarthras species and wild mammals.

Avaliou-se o comportamento ingestivo de vacas leiteiras com acesso restrito ou irrestrito a uma pastagem de alfafa suplementada com silagem de milho e concentrado. Utilizaram-se 16 vacas da raça Holandesa, em estádio médio de lactação, em delineamento em blocos ao acaso. Os tratamentos foram: silagem de milho substituída parcialmente por pastejo restrito ou irrestrito de alfafa. As vacas foram manejadas em sistema de pastejo rotacionado e a quantidade de concentrado foi igual em ambos os tratamentos. As atividades comportamentais observadas foram pastejo, ruminação e ócio, das oito às 19 horas, em quatro ocasiões. No pastejo irrestrito, observou-se que, nos horários entre 14 e 17 horas, o pastejo foi intermitente e de curta duração, enquanto no pastejo restrito a atividade de pastejo foi mais prolongada durante a manhã e no final da tarde. A restrição no tempo disponível para pastejo da alfafa influenciou marcadamente a distribuição, no decorrer do dia, do tempo gasto em pastejo, da ruminação e do ócio. Entretanto, não se observou este efeito no tempo total gasto nestas atividades.
The diurnal ingestive behavior of dairy cows on alfalfa pastures supplemented with corn silage and concentrate was evaluated. Sixteen Holstein dairy cows in mid-lactation were used in a randomized block design. The treatments were partial replacement of corn silage for limited alfalfa grazing time (LGT) or unlimited grazing time (UGT). Rotational alfalfa grazing was used and the amount of concentrate fed was the same in both treatments. Behavioral activities observed were time spent grazing, rumination and idleness, during four days, from 8:00 AM to 7:00 PM. From 2:00 to 5:00 PM grazing was intermittent and short-lasting on UGT, whereas on LGT grazing activity was longer than UGT in the morning and at the end of the afternoon. Restriction in available grazing time clearly influenced the distribution of time spent with grazing, rumination and idleness throughout the day. However, this effect was not observed in the total time spent in these activities.

Objetivo deste estudo foi analisar o equilíbrio postural de indivíduos neuropatas diabéticos, por meio de baropodometria, relacionando com prejuízos no sistema sensoriomotor. Vinte e oito pessoas saudáveis e 25 com diagnóstico de neuropatia diabética foram submetidas à avaliação estática (mensuração do deslocamento do centro de pressão corporal) e dinâmica (análise temporal da fase de apoio do ciclo da marcha). A sensibilidade tátil dos pés foi avaliada por meio de monofilamentos Semmes Weinstein e a força muscular isométrica do tornozelo por dinamometria. As análises de multivariânvia (MANOVAs) e de variância (ANOVAs) indicaram desempenho inferior na sensibilidade tátil, na força muscular e no equilíbrio dinâmico, porém não apontou diferença para o equilíbrio estático de neuropatas diabéticos. Com esse estudo por meio da análise de regressão, pode-se inferir que as diferenças do equilíbrio na marcha dos neuropatas podem ser resultantes da insensibilidade tátil e da força muscular.
Objective of this study was to analyze the postural balance of neuropathic diabetic individuals through baropodometry, related to losses in the sensorimotor system. Twenty-eight healthy and 25 diagnosed with diabetic neuropathy were subjected to static evaluation (measurement of displacement of body center of pressure) and dynamic (temporal analysis of the stance phase of gait cycle). The tactile sensitivity of the feet was assessed by Semmes Weinstein monofilaments and isometric muscle strength of ankle dynamometry. Analyses of multivariânvia (MANOVAs) and variance (ANOVAs) indicated lower performance in tactile sensitivity, muscle strength and dynamic balance, but showed no difference for static equilibrium of diabetic neuropathy. With this study by regression analysis, one can infer that the equilibrium differences in gait of neuropathic insensitivity may result from tactile and muscle strength.

Smoking is a chronic disease with damages to physical and mental health and to the social and economic life of the user. This study aimed to identify in the scientific literature the knowledge produced about tobacco dependence in schizophrenia and its utilization by nursing. An integrative review of the scientific literature was conducted, from May 2001 to May 2011, based on the following guiding questions: Is there a relationship between tobacco dependence and schizophrenia? Has this issue been approached by nursing? The papers were selected in MEDLINE and CAPES Periodicals Portal, from the descriptors: smoking, schizophrenia and nursing. Of the 346 papers found, attending to the inclusion criteria, the sample comprised52 papers, which were analyzed and discussed. It was found that the relationship between schizophrenia and smoking is unquestionable according to the scientific literature, and worrying because despite the apparent benefits (improvement of the negative symptoms, decrease of the adverse effects of the medicines, feeling of pleasure) there is interference in the drug therapy and impairment of disorder presentation. Of the 52 papers analyzed, only three mentioned the professional nurse, so evidencing the lack of positioning of nursing at the head of this issue. It was concluded that the association between smoking and schizophrenia is worrying and that nursing should include the approach to smoker as part of nursing care, offering psychiatric patients the opportunity to reflect on smoking in their life and on their willingness to receive help to quit the habit.
O tabagismo é uma doença crónica com prejuízos à saúde física, mental e à vida social e económica do usuário. Este estudo teve por objetivo, identificar na literatura científica o conhecimento produzido sobre a dependência de tabaco na esquizofrenia e sua utilização pela enfermagem. Foi realizada uma revisão integrativa da literatura científica, de maio de 2001 a maio de 2011, a partir das seguintes questões norteadoras: Existe relação entre dependência de tabaco e esquizofrenia? Esta temática tem sido abordada pela enfermagem? Os artigos foram selecionados no MEDLINE e no Portal de Periódicos da CAPES, a partir dos descritores: tabagismo, esquizofrenia e enfermagem. Dos 346 artigos encontrados, atendendo aos critérios, a amostra ficou constituída por 52 artigos, analisados e discutidos. Constatou-se que a relação entre esquizofrenia e tabagismo é inquestionável segundo a literatura científica e preocupante, pois apesar dos aparentes benefícios (melhora dos sintomas negativos, diminuição dos efeitos colaterais das medicações, sensação de prazer) há interferência na terapêutica medicamentosa e prejuízo na apresentação do transtorno. Dos 52 artigos analisados, apenas três fizeram menção ao profissional enfermeiro, evidenciando a falta de posicionamento da enfermagem diante desta temática. Conclui-se que a associação entre tabagismo e esquizofrenia é preocupante e que a enfermagem deve incluir a abordagem ao tabagista como parte do cuidado de enfermagem, oferecendo aos pacientes psiquiátricos a oportunidade de refletir sobre o tabagismo em sua vida e sobre sua real disposição para receber ajuda para abandonar o hábito.
El tabaquismo es una enfermedad crónica con perjuicio a la salud del cuerpo, mental, social y económica del usuario. Este estudio tuvo como objetivo identificar los conocimientos en la literatura científica producida sobre la dependencia del tabaco en la esquizofrenia y su utilización por la enfermería. Fue realizada una revisión integradora de la literatura científica, desde mayo 2001 hasta mayo 2011, desde las siguientes preguntas: ¿Existe relación entre la dependencia del tabaco y la esquizofrenia? ¿Esta temática ha sido abordada por la enfermería? Los artículos fueron seleccionados en el MEDLINE y en el Portal de Periódicos CAPES, siguiendo las palabras claves: tabaquismo, esquizofrenia y enfermería. De los 346 artículos encontrados, teniendo en cuenta los criterios, la muestra se quedó con 52 artículos, analizados y discutidos. Se constató que la relación entre la esquizofrenia y el tabaquismo es incuestionable según la literatura científica y preocupante, pues a pesar de los aparentes beneficios (mejora de los síntomas negativos, disminución de los efectos secundarios de los medicamentos, los sentimientos de placer) interfiere en el tratamiento de las drogas y perjuicio en la presentación del trastorno. De los 52 artículos analizados, solamente tres han hecho mención al profesional enfermero, lo que muestra una falta de posición de la enfermería en este tema. Se concluye que la asociación del tabaquismo y la esquizofrenia es preocupante y que el enfermero debe incluir el abordaje al fumador como parte del cuidado de la enfermería, ofreciendo a los sujetos pacientes psiquiátricos la oportunidad de reflexionar sobre el tabaquismo en su vida y su real disposición para recibir ayuda para dejar el hábito de fumar.
