Dependência funcional dentro e fora de casa em pessoas idosas com 75 anos ou mais: diferenças entre os sexos / Functional disability inside and outside of home of older adults aged 75 years and older: differences between males and females / Dependencia funcional dentro y fuera del hogar en ancianos de 75 años o más: diferencias entre sexos

O sexo é um importante fator a ser considerado na compreensão da dependência de cuidados na velhice. Objetivo:Verificar fatores associados à dependência, dentro e fora de casa, em pessoas idosas com 75 anos ou mais, com ênfase na diferença entre os sexos. Metodologia:Pesquisa transversal com dados do estudo FIBRA. A capacidade funcional nas Atividades Instrumentais de Vida Diária (AIVD) foi dividida em atividades realizadas dentro de casa (uso do telefone, manejo da medicação, tarefas domésticas e preparo da refeição) e atividades realizadas fora de casa (fazer compras, utilizar transporte e manejo do dinheiro). As variáveis independentes incluíram aspectos sociodemográficas e de saúde. Foram estimadas razões de prevalência por meio de modelos de regressão múltipla de Poisson a fim de verificar as variáveis associadas com dependência dentro e fora de casa. Resultados:A amostra foi composta por 804 idosos. Dentro de casa, não houve fatores associados à dependência para o sexo masculino. Enquanto para o sexo feminino, os fatores associados foram fragilidade (RP = 1,99; 95%IC: 1,26-3,15) e 80 anos e mais (RP = 1,41; 95%IC: 1,05-1,89). Quanto à dependência fora de casa, a fragilidade destacou-se como um fator associado a ambos os sexos, masculino (RP = 2,80 95%IC: 1,17-6,64) e feminino (RP = 1,98 95%IC: 1,24-3,17). Conclusões:Para o sexo feminino, a idade avançada e a fragilidade foram os fatores de maior associação com dependência, tanto para o ambiente dentro quanto fora de casa. Para o sexo masculino, a fragilidade foi o único e grande determinante de dependência nas atividades fora de casa, apresentando prevalência maior do que a encontrada na amostra do sexo feminino (AU).

Sexis an important factor to be considered tocomprehendoldage care dependencyObjective:Verify associated factors to dependency, in and out of home, in persons with 75 years or more, with emphasis on sexdifferences. Methodology:Cross-sectional research with data from the FIBRA Study. The functional dependence in Instrumental Activities of Daily Living (IADL) was divided in activities performed inside home (using telephone, managing medicine, housework and meal preparation) and activities performed outside home (shopping, transportation and managing finances).The independent variable included health and sociodemographic aspects. Estimates on prevalence ratios were made using multiple Poisson regression models to verify the many variables associated with dependency inside and outside home. Results:The sample was composed of 804 older people. Inside home there were not any factors associated with dependency in the males. However, in the females the associated factors were frailty (PR = 1.99; 95%CI: 1.26-3.15) and 80 and older (PR = 1.41; 95%CI: 1.05-1.89). As to dependency outside home, frailty was a factor that stood out in both sexes, male (PR = 2.80 95%CI: 1.17-6.64) and female (PR = 1.98 95%CI: 1.24-3.17). Conclusions:To women, older age and frailty were the strongest factors of dependency, to both inside and outside home. To men, frailty was the strongest and single dependency factor for dependency in outside activities, showing a higher prevalence than that of the female sex (AU).

Prevalence risk of sarcopenia in older Brazilian adults during the pandemic: A cross-sectional analysis of the Remobilize Study

ABSTRACT BACKGROUND: Social distancing has led to lifestyle changes among older adults during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVES: This study aimed to estimate the prevalence risk of sarcopenia (RS) and investigate its associated factors during the COVID-19 pandemic in older Brazilian adults. DESIGN AND SETTING: Cross-sectional observational analysis of baseline data as part of the Remobilize Study. METHODS: Participants in the study were older adults (≥ 60 years), excluding those who were bedridden or institutionalized. The data collected consisted of answers about the RS (SARC-F), functional status, walking, sedentary behavior (SB), pain, comorbidity, and life space mobility. RESULTS: A total of 1,482 older adults (70 ± 8.14 years, 74% women) participated in the study, and an RS prevalence of 17.1% was found. (95% confidence interval [CI] 15.25-19.15%). The adjusted multivariate model showed a significant association between RS and functional limitation (odds ratio [OR]: 19.05; CI 13.00-28.32), comorbidity (OR: 5.11; CI 3.44-7.81), pain (OR: 4.56; CI 3.33-6.28), total walking (OR: 0.99; CI 0.99-1.00), SB of 8-10 hours (OR: 1.85; CI 1.15-2.93), and SB of > 10 hours (OR: 3.93; CI 2.48-6.22). RS was associated with mobility during the pandemic (OR: 0.97; CI 0.96-0.98). P < 0.05. CONCLUSIONS: During the pandemic, the prevalence of RS in older Brazilians was estimated at 17.1%. Moderate to severe functional limitation, comorbidities, presence of pain, walking, longer SB period, and reduced life space mobility significantly contributed to RS in older adults during the pandemic.

Development of inclusion complex based on cyclodextrin and oxazolidine derivative

Abstract Oxazolidine derivatives (OxD) have been described as third-line antibiotics and antitumoral agents. The inclusion complexes based on cyclodextrin could improve the solubility and bioavailability of these compounds. A novel synthetic OxD was used, and its inclusion complexes were based on 2-hydroxy-beta-cyclodextrin (2-HPßCD). We conducted an in silico study to evaluate the interaction capacity between OxD and 2-HPßCD. Characterization studies were performed through scanning electron microscopy (SEM), Fourier-transformed infrared (FTIR), nuclear magnetic resonance spectroscopy (1H-NMR), X-ray diffraction (XRD), and thermal analyses. A kinetic study of the OxD was performed, including a cytotoxicity assay using peripheral blood mononuclear cells (PBMCs). The maximum increment of solubility was obtained at 70 mM OxD using 400 mM 2-HPßCD. SEM analyses and FTIR spectra indicated the formation of inclusion complexes. 1H-NMR presented chemical shifts that indicated 1:1 stoichiometry. Different thermal behaviors were obtained. The pharmacokinetic profile showed a short release time. Pure OxD and its inclusion complex did not exhibit cytotoxicity in PBMCs. In silico studies provided a foremost insight into the interactions between OxD and 2-HPßCD, including a higher solubility in water and an average releasing profile without toxicity in normal cells

Pectin-like Polysaccharide Extracted from the Leaves Caesalpinia pulcherrima is a Promising Antioxidant and Immunomodulator Agent

Abstract Studies have shown that Caesalpinia pulcherrima extracts promote antioxidant, healing, immunomodulating and antiparasitic activities and its polysaccharides can be used as functional food. In this sense, this work had as objective the isolation and characterization of a polysaccharide-like pectin, extracted from the C. pulcherrima leaves and its possible applications as an antioxidant and immunomodulator agent. The molecule was characterized by high performance liquid chromatography, fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy. Its antioxidant potential was evaluated through the methods of phosphomolybdenum, ABTS radical scavenging [2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid], DPPH (1,1-diphenyl-2-picrylhydrazyl) and nitric oxide radical. The immunostimulating effects of pectin were tested in splenocytes to evaluate its toxic, proliferative and cell activator and immunomodulatory potential. The polysaccharide obtained has structural characteristics similar to pectins. Pectin showed high in vitro antioxidant activity for ABTS radical scavenging, moderate activity for phosphomolybdenum and low activity for DPPH and nitric oxide. In vitro immunomodulation assays showed that pectin obtained did not promote a cytotoxic effect (viability > 90%). The increase in cytosolic ROS levels indicates a possible mechanism of cell activation without causing damage. Immunophenotyping showed that pectin increased a subpopulation of CD8+ T lymphocytes and monocytes. In addition, it promoted a mostly pro-inflammatory response confirmed by the production of cytokines IL-2, -4, -6, IFN-γ and TNF-α. These results reinforce the ethnopharmacological use of C. pulcherrima leaves and expand the use of this plant for future applications as herbal medicines.

Resumo Objetivo Identificar o perfil de mobilidade nos espaços de vida em idosos que vivem na comunidade e estabelecer a precisão dos pontos de corte desse instrumento para discriminar entre níveis de fragilidade, fragilidade em marcha e de risco de sarcopenia. Método Estudo observacional e metodológico com 391 participantes com 72 anos e mais (80,4±4,6), que responderam ao Life Space Assessment (LSA) e a medidas de rastreio de fragilidade e risco de sarcopenia usando respectivamente o fenótipo de fragilidade e o SARC-F. Os pontos de corte para fragilidade e risco de sarcopenia foram determinados por meio da Curva ROC (Receiver Operating Characteristic) com intervalos de confiança de 95%. Resultados A média da pontuação no LSA foi 53,6±21,8. Os pontos de corte de melhor acurácia diagnóstica foram ≤54 pontos para fragilidade em marcha (AUC= 0,645 95%; p<0,001) e ≤60 pontos para risco de sarcopenia (AUC= 0,651 95%; p<0,001). Conclusão A capacidade de idosos de se deslocar nos vários níveis de espaços de vida, avaliado pelo LSA demonstrou ser uma ferramenta viável que pode contribuir no rastreio de fragilidade em marcha e de risco de sarcopenia e, com isso, prevenir desfechos negativos.

Abstract Objective To identify the profile of a sample of older people recruited at home based on a measure of life-space mobility and to establish the accuracy of the cut-off points of this instrument for discriminating between levels of frailty, frailty in walking speed and risk of sarcopenia. Method An observational methodological study of 391 participants aged ≥72 (80.4±4.6) years, who answered the Life-Space Assessment (LSA) and underwent frailty and risk of sarcopenia screening using the frailty phenotype and SARC-F measures, respectively, was performed. The cut-off points for frailty and risk of sarcopenia were determined using ROC (​​Receiver Operating Characteristic) curves and their respective 95% confidence intervals. Results Mean total LSA score was 53.6±21.8. The cut-off points with the best diagnostic accuracy for total LSA were ≤54 points for frailty in walking speed (AUC=0.645 95%; p<0.001) and ≤60 points for risk of sarcopenia (AUC=0.651 95%; p<0.001). Conclusion The ability of older people to move around life-space levels, as assessed by the LSA, proved a promising tool to screen for frailty in walking speed and risk of sarcopenia, thus contributing to the prevention of adverse outcomes.

Prenatal factors associated with fetal visceral adiposity / Fatores pré-natais associados à adiposidade visceral fetal

Abstract Objective: To assess fetal visceral adiposity and associated factors during pregnancy. Methods: Secondary analysis of prospective cohort data with 172 pairs (pregnant woman/fetus) treated at public health units. Anthropometric data, metabolic (glucose, glycated hemoglobin, insulin, insulin resistance, total cholesterol and fractions, triglycerides) measures, fetal biometry, and visceral and subcutaneous adiposity in the binomial (pregnant woman/fetus) were evaluated at the 16th, 28th and 36th gestational weeks by ultrasonography. Pearson's correlation coefficient and multiple linear regression were used, with a significance level of 5%. Results: At the 16th week, the mean age of the pregnant women was 26.6 ± 5.8 years and mean weight was 62.7 ± 11.5 kg; 47.0% had normal weight, 28.3% were overweight, 13.3% were underweight, and 11.2% were obese. At 36 weeks, 44.1% had inadequate gestational weight gain, 32.5% had adequate gestational weight gain, and 23.3% had excessive gestational weight gain. Fetal visceral adiposity at week 36 showed a positive correlation with maternal variables: weight (r = 0.15) and body mass index (r = 0.21) at the 16th; with weight (r = 0.19), body mass index (r = 0.24), and gestational weight gain (r = 0.21) at the 28th; and with weight (r = 0.22), body mass index (r = 0.26), and gestational weight gain (r = 0.21) at the 36th week. After multiple linear regression, adiposity at the 28th week remained associated with fetal variables: abdominal circumference (p < 0.0001), head circumference (p = 0.01), area (p < 0.0001), and thigh circumference (p < 0.001). At the 36th week, adiposity remained associated with the abdominal circumference of the 28th (p = 0.02) and 36th weeks (p < 0.001). Conclusion: Adiposity was positively correlated with the measurements of the pregnant woman. After the multivariate analysis, the persistence of the association occurred with the abdominal circumference, a central adiposity measurement with a higher metabolic risk.

Na 36a semana com circunferência abdominal da 28a (p = 0,02) e 36a semana (p < 0,001). Conclusão: A adiposidade foi positivamente correlacionada com medidas da gestante, após análise multivariada a persistência da associação deu-se com a circunferência abdominal, medida de adiposidade central, de maior risco metabólico.

Fatores Associados à satisfação com a vida de idosos usuários de unidades básicas de saúde / Associated factors in satisfaction with the life of elderly users of basic health units / Fatores asociados a la satisfacción con la vida de los ancianos usuarios de unidades básicas de salud

Este estudo investigou os fatores associados à satisfação com a vida de 654 idosos usuários de Unidades Básicas de Saúde de Maringá, Paraná. Foi utilizado um questionário sociodemográfico, o International Physical Activity Questionnaire (IPAQ) e a Escala de Satisfação com a Vida. A análise dos dados foi realizada por meio dos testes de Kruskal-Wallis, Mann-Whitney e correlação de Spearman (p < 0,05). Verificou-se que os idosos com menor poder aquisitivo que se perceberam com saúde ruim e tomam medicamentos regularmente são menos satisfeitos com a vida do que seus pares. Os idosos fisicamente ativos se mostraram mais satisfeitos com a vida do que os sedentários/irregularmente ativos. A satisfação com a vida se associou com os dias de caminhada por semana (r = 0,15). Conclui-se que a renda familiar, a percepção de saúde, o uso de medicamentos e a atividade física são fatores intervenientes na satisfação com a vida.

This study investigated the associated factors involved in life satisfaction of 654 elderly users of Basic Health Units of Maringá, Paraná. A sociodemographic questionnaire was used, the International Physical Activity Questionnaire (IPAQ) and the Life Satisfaction Scale. Data analysis was performed using the Kruskal-Wallis, Mann-Whitney, and Spearman correlation tests (p < 0.05). Older people with lower purchasing power who were perceived with poor health and who take medications regularly are less satisfied with life than their peers (p < 0.05). The physically active elderly were more satisfied with life than the sedentary/irregularly active (p = 0.004). Satisfaction with life correlated with walking days per week (r = 0.15). It is concluded that family income, health perception, medication use, and physical activity are factors that intervene in life satisfaction.

El análisis de los datos fue realizado por medio de las pruebas de Kruskal-Wallis, Mann-Whitney y correlación de Spearman (p < 0,05). Se verificó que los ancianos con menor poder adquisitivo que se percibieron con mala salud y que toman medicamentos regularmente son menos satisfechos con la vida que sus pares. Los ancianos físicamente activos se mostraron más satisfechos con la vida que los sedentarios/irregularmente activos. La satisfacción con la vida se asoció con los días de caminata por semana (r = 0,15). Se concluye que la renta familiar, la percepción de salud, el uso de medicamentos y la actividad física son factores intervinientes en la satisfacción con la vida.

Metabolic syndrome in pregnancy and postpartum: prevalence and associated factors

SUMMARY OBJECTIVE Evaluate the prevalence of metabolic syndrome (MS) and the main associated maternal factors in women without pre-gestational conditions, in early pregnancy and in the immediate postpartum. METHODS Two hundred pregnant women were evaluated at the 16th week of pregnancy, and 187 were reassessed postpartum. MS was diagnosed according to the criteria by the National Cholesterol Education Program Adult Treatment Panel III. In addition to the diagnostic criteria, anthropometric measures, blood pressure, metabolic profile, and visceral and subcutaneous fat thickness (by ultrasonography) were collected from the pregnant woman. The student's t-test was used to compare the prevalence of MS and its components in the 16th week and in the postpartum. Multiple logistic regression was performed to identify the principal factors associated with the syndrome. RESULTS The prevalence of the MS was 3.0% in early pregnancy and 9.7% postpartum (p=0.01). Following multiple logistic regression, the prepregnancy body mass index (BMI) (p=0.04) and high-density lipoprotein cholesterol (HDL-c) (p=0.02) remained associated with MS at 16 weeks, and triglyceride levels evaluated in postpartum (p<0.001) with MS in postpartum. CONCLUSION The frequency of the MS was high in the immediate postpartum. The factors associated were prepregnancy BMI and HDL-c at the 16th week, as well as triglyceride levels postpartum.

RESUMO OBJETIVO Avaliar a prevalência da SM e os principais fatores maternos associados em mulheres sem doenças pré-gestacionais, no início da gravidez e no pós-parto imediato. MÉTODOS Foram avaliadas 200 mulheres na 16a semana de gravidez, sendo 187 reavaliadas no pós-parto. A SM foi diagnosticada de acordo com os critérios do National Cholesterol Education Program Adult Treatment Panel III. Além dos critérios diagnósticos da síndrome, foram coletadas medidas antropométricas, pressão arterial, perfil metabólico e espessura de gordura visceral e subcutânea (através de ultrassonografia) da gestante. O teste t de Student foi usado para comparar a prevalência de SM e dos seus componentes nos dois momentos. Os modelos de regressão logística múltipla, para investigar os principais fatores associados à síndrome na 16a semana de gestação e no pós-parto. RESULTADOS A prevalência da SM foi de 3,0% no início da gravidez e 9,7% no pós-parto (p=0,01). O índice de massa corporal (IMC) pré-gravídico (p=0,04) e o colesterol lipoproteínas de alta densidade (HDL-c) (p=0,02) permaneceram associados à SM na 16a semana. Após o parto, os níveis de triglicerídeos permaneceram associados à SM no pós-parto (p<0,001). CONCLUSÃO A prevalência da SM foi alta no pós-parto imediato e os fatores associados à síndrome foram IMC pré-gravídico e HDL-c na 16a semana, e níveis triglicerídeos no pós-parto.

Ability of two new thiazolidinediones to downregulate proinflammatory cytokines in peripheral blood mononuclear cells from children with asthma

Allergic asthma is a chronic, complex inflammatory disease of the airway. Despite extensive studies on the immunomodulation of T helper (Th) cell pathways (i.e., Th1 and Th2) in asthma, little is known about the effects of Th17 pathway modulation, particularly that involving peroxisome proliferator-activated receptors (PPARs). In response, two new thiazolidinedione derivatives-namely, LPSF-GQ-147 and LPSF-CR-35 were synthesized and evaluated for their immunomodulatory effects on Th17-related cytokines, including interferon γ (IFNγ), interleukin IL-6, IL-17, and IL-22 in the peripheral blood mononuclear cells of asthmatic children. Both compounds were nontoxic even at high concentrations (i.e., 100 µM). The LPSF-CR-35 compound significantly reduced the levels of IL-17A (p = .039) and IFNγ (p = .032) at 10 µM. For IL-22 and IL-6, significant reduction occurred at 100 µM (p = .039 and p = .02, respectively). Conversely, LPSF-GQ-147 did not significantly inhibit the production of the tested cytokines, the levels of all of which were more efficiently reduced by LPSF-CR-35 than methylprednisolone, the standard compound. Real-time polymerase chain reaction assay confirmed that LPSF-GQ-147 has significant PPARγ modulatory activity. Such data indicate that both LPSF-CR-35 and LPSF-GQ-147 are promising candidates as drugs for treating inflammation and asthma

INVASIVE TRIPLE NEGATIVE BREAST CANCER WITH BASAL AND NON-BASAL-LIKE IMMUNOPHENOTYPES: PROGNOSTIC IMPLICATIONS / Carcinoma invasivo de mama triplo negativo com imunofenótipo basal e não basal: implicações prognósticas Darley de Lima Ferreira Filho1*, Nancy Cristina Ferraz de Lucena Ferreira1, Maria do Carmo Abreu

Objectives: The objective of the study was to compare the postoperative staging and clinical development outcomes in a period of three years with the histopathological and immunohistochemical characteristics considered prognostic and/or predictive factors in patients being treated for triple negative type of breast cancer in the Barão Lucena Hospital, Recife, Pernambuco. Method: The study was conducted with 125 female patients suffering from triple negative breast cancer who underwent surgical treatment in the mastology service of Barão Lucena Hospital from 2009 to 2012. The clinical and pathological features of the tumors were studied and correlated with basal and non-basal subtypes. A descriptive data analysis was carried out using tables and/or graphs for qualitative variables. Association analysis was performed using χ2 test for independence. In tables that showed expected frequency lower than 5, in more than 20% of cells, we used the Fisher's exact test. In addition, the odds ratio (OR) and the confidence interval (CI) for OR were calculated. In the entire analysis, a 5% significance level was considered. Results: M ean a ge w as 4 9 y ears; r egarding r ace, b lack w as p resent i n 8 3 ( 66.4%). The most common histological type was ductal, in 111 (88.8%). The pathological stage I/II was the most common, in 87 (69.6%) patients. A total of 71 patients (56.8%) showed no axillary metastasis. Regarding the type of surgery, the conservative one was performed in 57 (45.6%), including sectorectomy and oncoplastic surgery. The recurrence was present in 30 patients, basal in 16 (53.3%) patients and 14 (46.7%) in the non-basal, and bone metastasis was the most frequent. Conclusion: In this triple-negative tumor sample, the most important facts related to survival were: being aged less than 40 years, histological type, cytokeratin CK5/6 and higher significance level of the factors EGFR and KI-67.

Objetivos: O objetivo do estudo foi correlacionar o estadiamento pós-cirúrgico e a evolução clínica em um período de três anos com as características histopatológicas e imunoistoquímicas consideradas fatores prognósticos e/ou preditivos nas pacientes em tratamento de câncer de mama do tipo triplo negativo do Hospital Barão de Lucena, Recife, Pernambuco. Método: O estudo foi feito com 125 pacientes do sexo feminino portadoras de câncer de mama triplo negativo e que foram submetidas a tratamento cirúrgico no serviço de mastologia do Hospital Barão de Lucena no período de 2009 a 2012. Nessas pacientes foram estudadas as características clínicas e patológicas dos tumores, as quais foram correlacionadas com os subtipos basal e não basal. A análise descritiva dos dados foi feita através de tabelas e/ou gráficos para variáveis qualitativas. Para análise de associação, foi utilizado o teste do χ2 para independência. Nas tabelas que apresentaram frequência esperada menor que 5, em mais de 20% das caselas, foi utilizado o teste exato de Fisher. Além disso, foi calculada a razão de chance (OR) e o intervalo de confiança (IC) para OR. Em toda a análise foi considerado nível de significância de 5%. Resultados: A média de idade foi de 49 anos; com relação à raça, tivemos a cor negra em 83 (66,4%) delas. O tipo histológico mais comum foi o ductal, em 111 (88,8%) pacientes. O estágio patológico I/II foi o mais comum, em 87 (69,6%) delas. Um total de 71 (56,8%) pacientes não demonstrou comprometimento axilar. Com relação ao tipo de cirurgia, a conservadora foi utilizada em 57 (45,6%) pacientes, incluindo setorectomia e técnicas de oncoplastia. A recorrência esteve presente em 30 pacientes, sendo basal em 16 (53,3%) e não basal 14 (46,7%) delas, nas quais a metástase óssea foi a mais frequente. Conclusão: Nessa amostra de tumores triplo negativo, os fatos mais importantes associados à sobrevida foram a idade abaixo de 40 anos, o tipo histológico, a citoqueratina CK5/6 e o grau de significância maior dos fatores EGFR e KI-67.

Prática de atividade física por idosos frequentadores de unidades básicas de saúde / Practice of physical activity by elderly frequenters of basic health units

Objetivo: O objetivo do presente estudo foi identificar os fatores associados à atividade física de idosos usuários das unidades básicas de saúde (UBS) do município de Matelândia, Paraná. Métodos: Trata-se de um estudo transversal, no qual foram pesquisados 343 idosos usuários das UBS do município. Foi utilizado um questionário sociodemográfico, o International Physical Activity Questionnaire (IPAQ), e o questionário de barreiras para prática de atividade física. Resultados: Em relação ao nível de atividade física, 88,9% dos idosos avaliados foram classificados como ativos/muito ativos. Maior nível de atividade física foi significativamente associado a quantidade de medicamentos utilizados (p = 0,024), motivo para ir à UBS (p = 0,037) e indicação de atividade física pela UBS (p = 0,040). A falta de energia (p = 0,048) foi é uma barreira mais frequente e significativa para os idosos ativos/muito ativos. Conclusão: É grande o número de idosos ativos/muito ativos usuários das UBS de Matelândia, Paraná, e este foi associado à menor faixa etária, ao menor uso de medicamentos, à ida à UBS para retirada de medicamento/outros e à indicação de atividade física pela UBS. Para aqueles que não se enquadram nesses níveis, a falta de recursos financeiros e o ambiente insuficientemente seguro são as barreiras mais frequentes para a prática de atividades físicas.

Objectives: This study aimed to identify the factors associated with the physical activity of elderly assisted at the basic health units (BHU) of the city of Matelândia, Paraná, Brazil. Methods: This is a cross-sectional study, in which 343 elderly users of the BHU of this city were surveyed. A socio-demographic questionnaire, the International Physical Activity Questionnaire (IPAQ), and the questionnaire of barriers to physical activity practice were used. Results: In relation to the level of physical activity, 88.9% of the elderlies were classified as active/very active. Higher level of physical activity was significantly associated with the amount of medication used (p = 0.024), reason to go to BHU (p = 0.037), and indication of physical activity by UBS (p = 0.040). Lack of energy (p = 0.048) was a more frequent and significant barrier for the active/very active elderly. Conclusion: There is a large number of active/very active elderly users of the BHU of Matelândia, Paraná, Brazil, and this was associated with lower age, lower medication use, going to BHU to withdraw medication/others and indication of physical activity by the BHU. For those who do not fit into these levels, lack of financial resources and insufficiently safe environment are the most common barriers to physical activity.

A new model for describing remission times: the generalized beta-generated Lindley distribution

New generators are required to define wider distributions for modeling real data in survival analysis. To that end we introduce the four-parameter generalized beta-generated Lindley distribution. It has explicit expressions for the ordinary and incomplete moments, mean deviations, generating and quantile functions. We propose a maximum likelihood procedure to estimate the model parameters, which is assessed through a Monte Carlo simulation study. We also derive an additional estimation scheme by means of least square between percentiles. The usefulness of the proposed distribution to describe remission times of cancer patients is illustrated by means of an application to real data.

Oral phaeohyphomycosis in a patient with squamocellular carcinoma of the lip: second case report

Abstract This communication reports the second known case of oral phaeohyphomycosis in a patient with squamocellular carcinoma of the lip. The patient, an 82-year-old black woman, a former smoker (for more than 30 years), suffering from an ulcerous vegetative lesion in the middle third of the lower lip for approximately 12 months. The result of the histopathological analysis indicated carcinoma, with well-differentiated keratinized squamous cells and the presence of septate mycelial filaments. In the direct mycological examination, thick and dematiaceous septate mycelial filaments were observed. After the resection surgery, the patient did not need to use an antifungal drug to treat the phaeohyphomycosis, and no follow-up radiotherapy was needed to treat the squamocellular carcinoma. We stress that the presence of the squamocellular lesion of the lip was a possible contributing factor to the infection.

Synthesis and biological evaluation of novel imidazolidine derivatives as candidates to schistosomicidal agents

ABSTRACT Introduction: Schistosomiasis is an infectious parasitic disease caused by trematodes of the genus Schistosoma, which threatens at least 258 million people worldwide and its control is dependent on a single drug, praziquantel. The aim of this study was to evaluate the anti-Schistosoma mansoni activity in vitro of novel imidazolidine derivatives. Material and methods: We synthesized two novel imidazolidine derivatives: (LPSF/PTS10) (Z)-1-(2-chloro-6-fluorobenzyl)-4-(4-dimethylaminobenzylidene)-5-thioxoimidazolidin-2-one and (LPSF/PTS23) (Z)-1-(2-chloro-6-fluoro-benzyl)-5-thioxo-4-(2,4,6-trimethoxy-benzylidene)-imidazolidin-2-one. The structures of two compounds were determined by spectroscopic methods. During the biological assays, parameters such as motility, oviposition, mortality and analysis by Scanning Electron Microscopy were performed. Results: LPSF/PTS10 and LPSF/PTS23 were considered to be active in the separation of coupled pairs, mortality and to decrease the motor activity. In addition, LPSF/PTS23 induced ultrastructural alterations in worms, after 24 h of contact, causing extensive erosion over the entire body of the worms. Conclusion: The imidazolidine derivatives containing the trimetoxy and benzylidene halogens showed promising in vitro schistosomicidal activity.

Objetivo: O presente trabalho tem como objetivo sistematizar evidências científicas sobre a utilização dos exercícios de alongamento muscular no tratamento da fibromialgia (FM). Metodologia: Foi realizado a partir de consulta retrospectiva, sem limite cronológico e linguístico, às bases de dados MedLine, LILACS, SciELO e PEDro, além da ferramenta de busca PubMed. A coleta foi realizada por dois revisores independentes, em outubro de 2012, sendo a estratégia de busca formulada por meio do cruzamento de descritores e termos relevantes para o tema nos idiomas inglês, português e espanhol. Foram incluídos ensaios clínicos randomizados (ECRs) compostos apenas por pacientes com diagnóstico clínico de FM e com exercícios de alongamento muscular como medida terapêutica em pelo menos um dos grupos de intervenção. Os estudos incluídos foram avaliados quanto à qualidade metodológica por meio da escala PEDro, e suas referências bibliográficas, analisadas, para se destacar fontes adicionais. A busca totalizou 6.794 artigos. Cinco artigos foram selecionados, sendo um deles excluído por apresentar baixa qualidade metodológica. A dor foi avaliada por unanimidade. O método e o tempo das intervenções variaram amplamente, houve falta de menção de parâmetros na utilização dos alongamentos e ausência de exames físicos específicos. Resultados: Houve melhora significativa em todos os estudos quanto à dor, além de aspectos relacionados a qualidade de vida e condição física. Conclusão: É evidente a importância do alongamento muscular no tratamento da FM, porém observa-se a necessidade de novos estudos para se estabelecer os reais benefícios da técnica, visto que a maioria dos trabalhos publicados apresenta baixa qualidade metodológica e ausência de padronização quanto ao uso desse recurso. .

Objective: this study has the objective to systematize scientific evidences about the use of muscle stretching exercises in the treatment of FM. Methodology: it was performed from retrospective research without chronological and linguistic limits, at databases of MEDLINE, LILACS, SciELO and PEDro, as well as at PubMed search tool. Data collection was performed by two independent reviewers in October 2012, with the search strategy formulated by crossing descriptors and relevant terms to the topic in English, Portuguese and Spanish languages. Randomized clinical trials, only with patients with a clinical diagnosis of fibromyalgia and muscle stretching exercises as a therapeutic measure at least in one of the intervention groups were included. Included studies were assessed for methodological quality using PEDro scale and their references analyzed to highlight additional sources. The search amounted to an average of 6,794 items. Only five articles were selected, one being excluded because of its low methodological quality. Pain was assessed unanimously. The method and timing of interventions varied widely, there was poor mention of the parameters used in the stretches and absence of specific physical examinations. Results: there was significant improvement in all studies regarding pain, besides as related to quality of life and physical condition. Conclusion: it is clear the importance of muscle stretching in the treatment of FM, however, there is a need for further studies to establish the real benefits of the technique, because the majority of published studies shows low methodological quality and there is a lack of standardization regarding the use of this resource. .

Validation of a UV-spectrophotometric analytical method for determination of LPSF/AC04 from inclusion complex and liposomes

The aim of this study was to develop and validate a UV spectrophotometric method for determination of LPSF/AC04 from inclusion complex and encapsulated into liposomes. The validation parameters were determined according to the International Conference on Harmonisation (ICH) and National Health Surveillance Agency (ANVISA) guidelines. LPSF/AC04 was determined at 250 nm in methanol by a UV spectrophotometric method, exhibiting linearity in the range from 0.3 to 2 µg.mL−1 (Absorbance=0.18068 x [LPSF/AC04 µg.mL-1] + 0.00348), (r2=0.9995). The limits of detection and quantification were 0.047µg.mL−1 and 0.143µg.mL−1, respectively. The method was accurate, precise, reproducible and robust since all the samples analyzed had coefficient of variation of less than 5% and no statistically significant difference between theoretical and practical concentrations was detected. Thus, a rapid, simple, low cost and sensitive spectrophotometric method was developed and validated for determining the content of inclusion complex and liposomes containing LPSF/AC04.

O objetivo deste estudo foi desenvolver e validar um método espectrofotométrico para determinação do LPSF/AC04 em complexo de inclusão e encapsulado em lipossomas. Os parâmetros de validação foram determinados de acordo com o International Conference on Harmonisation (ICH) e Agência Nacional de Vigilância Sanitária (ANVISA). OLPSF/AC04 foi determinado a 250 nm em metanol pelo método espectrofotométrico UV, que apresenta linearidade na faixa de 0,3 a 2 µg/mL (Absorbância = 0,18068 x [LPSF/AC04 µg/mL] + 0,00348), (r2 = 0,9995). Os limites de detecção e quantificação foi 0,047 µg/mL e 0,143 µg/mL, respectivamente. O método foi exato, preciso, reprodutível e robusto e todas as amostras analisadas apresentaram coeficiente de variação menor que 5% e não houve diferença estatisticamente significante entre a concentração teórica e a prática. Assim, um método espectrofotométrico rápido, simples, sensível e de baixo custo foi desenvolvido e validado para determinar o conteúdo do LPSF/AC04 em complexos de inclusão e encapsulados em lipossomas.
