Redes Sociais Pessoais de Idosos com e sem Filhos

Objetivos: O presente estudo tem como objectivo analisar as redes sociais e pessoais de idosos portugueses com filhos e sem filhos, relativamente às características estruturais, funcionais e relacionais-contextuais. Metodologia: Para a avaliação das variáveis em estudo foram utilizados: o Instrumento de Análise da Rede Social Pessoal, versão para idosos (IARSP – Idosos) (Guadalupe, 2010; Guadalupe & Vicente, 2012) para avaliar as dimensões da rede social pessoal; um inquérito por questionário para caracterização da amostra a nível sociodemográfico e sociofamiliar. Participantes: A amostra é constituída por 418 idosos, com uma média de idades de 76 anos (DP=7,62), entre os 65 anos e os 98 anos, maioritariamente do sexo feminino (63,9%), casados ou em união facto (51,0%) e com escolaridade (63,9,1%). A maioria dos idosos inquiridos vive com agregado familiar (80,4%) em zonas rurais (64,8) e não usufrui de qualquer tipo de apoio de resposta social (71,5%). Resultados: Os idosos com filhos são maioritários (n=364; 87,1%) e os sem filhos os minoritários (n=54; 12,9%) na nossa amostra. Dos que têm filhos, 29,9% (109) têm filhos únicos e 70,1% (255) têm mais do que um filho (67% com 1 ou 2 filhos), sendo os filhos maioritariamente de ambos os sexos (n=158; 43,4%). Os resultados sugerem que o facto de os idosos terem ou não terem filhos reflete-se sobretudo em diferenças nas características estruturais das redes. Os idosos com filhos apresentam uma média mais elevada no tamanho da rede, na proporção das relações de familiares, e satisfação da rede e reciprocidade de apoio (p ≤ 0,001), a nível das características funcionais. Já relativamente à proporção das relações de amizade, vizinhança na rede, são os idosos sem filhos que apresentam uma média substantivamente mais elevada (p ≤ 0,003) do que a outra subamostra, apresentando também uma maior durabilidade das relações interpessoais (p < 0,03). As correlações entre o número total de filhos/as com as características estruturais e funcionais da rede, indicam-nos que quanto maior é o número de filhos maior é o tamanho da rede, a proporção das relações familiares, o apoio emocional, a reciprocidade de apoio, a satisfação com a rede e com o suporte social. Conclusões: O nosso estudo revela que as redes sociais pessoais dos idosos diferenciam-se a nível estrutural segundo o facto de terem ou não filhos, mas também nalgumas variáveis funcionais. Os idosos com filhos apresentam redes mais alargadas e muito centradas nas relações familiares na rede (sensivelmente menos um terço) do que os idosos sem filhos. Os últimos apresentam redes menores (com cerca de 2 pessoas a menos) e mais investidas nas relações de amizade e de vizinhança (com proporções que representam mais do dobro destes vínculos). / Goals: The present study has the purpose to analyze the personal social networks of Portuguese elder with our without sons/daughters, in their structural, functional and contextual relations. Methodology: We used for the evaluation of the variables: The Personal Social Network Analysis Tool, regarding elderly people (IARSP – elderly people) (Guadalupe, 2010; Guadalupe & Vicente, 2012), to evaluate the personal social network dimensions; a survey through an inquiry to characterize the sample at sociodemographic and at sociofamily level. Participants: The sample includes 418 elderly with an average age of 76 years old (DP = 7,62) between 65 and 98 years old, mainly women (63,9%), married or living as a couple (51,0%) with education (63,9,1%). Most of the elderly people who answered the survey live in family household (80,4%) in rural areas (64,8) and do not benefit from any type of social services support (71,5%). Results: The majority is elderly people with sons/daughters (n=364, 87,1%) and the ones without are the minority (n= 54, 12,9%) in our sample. Within those who are parents, 29,9% (109) have only one child and 70,1% (255) have more than one child (67% with 1 or 2), and the children are mainly of both sexes (n= 158; 43,4%). The results suggest that the fact that the elderly have or not have children is reflected especially in differences in the structural characteristics of the networks. Elderly people with children have a higher average in the network size, in the proportion of family relationships, and satisfaction of the network and reciprocal support (p ≤ 0,001). Regarding the proportion of friendly relations, network neighborhood, are the elderly without children who have a substantially higher mean (p ≤ 0,003) than the other subsample, also featuring improved durability of interpersonal relationships (p < 0,003). The correlations between the total number of children/with the structural and functional characteristics of the network, indicate that the greater the number of children, the greater the size of the network, the proportion of family relationships, emotional, support, reciprocity support and satisfaction with social network. Conclusion: Our study reveals that the personal social networks of the elderly differ in the structural level, according to whether they have sons/daughters or not, but also in some functional variables. The elderly with children have networks much more broader and centered on family relationships (roughly one-third) than elderly without children. These elderly without children have smaller networks (about 2 fewer people) and more centered in relations of friendship and neighborhood (with proportions that are more than the double compared to the other subsample).

Indigofera tinctoria Linn (Fabaceae) attenuates cognitive and behavioral deficits in scopolamine-induced amnesic mice

Purpose: To investigate the cognition-enhancing effects of aqueous extract of Indigofera tinctoria Linn (ITE, Fabaceae) in experimental amnesic mice. Methods: Scopolamine (2 mg/kg, i.p.) was used to induce amnesia in mice. The cognitive-enhancing activity of the ITE (5, 10 and 20 μg/mL) was studied by passive avoidance response, elevated plus maze and Y-maze behavioral paradigm in normal and scopolamine-induced amnesic mice. Antioxidant activities were also determined based on the ability of ITE to inhibit lipid peroxide, superoxide and hydroxyl radicals. Results: Scopolamine-induced cognitive deficits were significantly reversed by ITE (p < 0.001 at 20 mg/kg) in a dose-dependent fashion in all the behavioral paradigms tested. Furthermore, ITE dosedependently scavenged lipid peroxide, superoxide and hydroxyl free radicals with 50 % inhibition concentration (IC50) of 7.28 ± 0.37, 5.25 ± 0.28 and 7.62 ± 0.43 μg/mL, respectively. Conclusion: ITE possesses cognitive-enhancing properties in amnesic mice due to its potent antioxidant action.

Uso de dexmedetomidina como tratamiento coadyuvante de síndrome de abstinencia alcohólica: revisión sistemática

El objetivo de este estudio es establecer si la dexmedetomidina (DEX) es segura y efectiva para el manejo coadyuvante de síndrome de abstinencia a alcohol (SAA) a través de la búsqueda de evidencia científica. Metodología: se realiza una revisión sistemática de literatura publicada y no publicada desde enero de 1989 hasta febrero 2016 en PubMed, Embase, Scopus, Bireme, Cochrane library y en otras bases de datos y portales. Los criterios de inclusión fueron ensayos clínicos aleatorizados y no aleatorizados, estudios cuasi-experimentales, estudios de cohorte, y estudios de casos y controles; que incluyeron pacientes mayores de 18 años hospitalizados con diagnóstico de SAA y donde se usó DEX como terapia coadyuvante. Resultados: 7 estudios, 477 pacientes, se incluyeron en el análisis final. Se encontraron dos ensayos clínicos aleatorizados, tres estudios de casos y controles y dos estudios de cohorte retrospectivo. Solo uno de los estudios fue doble ciego y utilizó placebo como comparador. Análisis y conclusiones: en los estudios experimentales se determinan que el uso de DEX como terapia coadyuvante en el manejo de SAA tiene significancia clínica y estadística para disminuir dosis de BZD en las primeras 24 horas de tratamiento; pero no demostraron tener otros beneficios clínicos. En los estudios no aleatorizados existe consenso que relaciona el uso de DEX con menores dosis de BZD de forma temprana. Recomendaciones: no se recomienda el uso de DEX en SAA de forma rutinaria. Se recomienda usar DEX solo en casos en el que exista evidencia fallo terapéutico a BZD.

Inclusive cross section and double helicity asymmetry for pi(0) production in p plus p collisions at root s=62.4 GeV

The PHENIX experiment presents results from the RHIC 2006 run with polarized p + p collisions at root s = 62.4 GeV, for inclusive pi(0) production at midrapidity. Unpolarized cross section results are measured for transverse momenta p(T) = 0.5 to 7 GeV/c. Next-to-leading order perturbative quantum chromodynamics calculations are compared with the data, and while the calculations are consistent with the measurements, next-to-leading logarithmic corrections improve the agreement. Double helicity asymmetries A(LL) are presented for p(T) = 1 to 4 GeV/c and probe the higher range of Bjorken x of the gluon (x(g)) with better statistical precision than our previous measurements at root s = 200 GeV. These measurements are sensitive to the gluon polarization in the proton for 0.06 < x(g) < 0.4.

Antinociceptive and anti-inflammatory properties of 7-hydroxycoumarin in experimental animal models: potential therapeutic for the control of inflammatory chronic pain

Objectives In the present study we investigated the anti nociceptive, anti-inflammatory and antipyretic effects of 7-hydroxycoumarin (7-HC) in animal models. Methods The effects of oral 7-HC were tested against acetic acid-induced writhing, formalin test, tail flick test, complete Freund`s adjuvant (CFA)-induced hypemociception, carrageenan-induced paw oedema, lipopolysaccharide-induced fever and the rota rod test. Key findings 7-HC (3-60 mg/kg) produced a dose-related antinociception against acetic acid-induced writhing in mice and in the formalin test. In contrast, treatment with 7-HC did not prevent thermal nociception in the tail flick test. A single treatment with 7-HC, 60 mg/kg, produced a long-lasting antinociceptive effect against CFA-induced hypernociception, a chronic inflammatory pain stimulus. Notably, at 60 mg/kg per day over 4 days the administration of 7-HC produced a continuous antinociceptive effect against CFA-induced hypernociception. 7-HC (30-120 mg/kg) produced anti-inflammatory and antipyretic effects against carrageenan-induced inflammation and lipopolysaccharide-induced fever, respectively. Moreover, 7-HC was found to be safe with respect to ulcer induction. In the rota rod test, 7-HC-treated mice did not show any motor performance alterations. Conclusions The prolonged antinociceptive and anti-inflammatory effects of 7-HC, in association with its low ulcerogenic activity, indicate that this molecule might be a good candidate for development of new drugs for the control of chronic inflammatory pain and fever.

Relationship of high energy expenditure and variation in dietary intake with reporting accuracy on 7 day food records and diet histories in a group of healthy adult volunteers

Objectives: To assess the accuracy of reporting from both a diet history and food record and identify some of the characteristics of more accurate reporters in a group of healthy adult volunteers for an energy balance study. Design: Prospective measurements in free-living people. Setting: Wollongong, Australia. Subjects: Fifteen healthy volunteers (seven male, eight female; aged 22 -59 y; body mass index (BMI) 19 - 33 kg/m(2)) from the local community in the city of Wollongong, Australia. Interventions: Measurement of energy intake via diet history interview and 7 day food records, total energy expenditure by the doubly labelled water technique over 14 days, physical activity by questionnaire, and body fat by dual-energy X-ray absorptiometry. Results: Increased misreporting of energy intake was associated with increased energy expenditure (r = 0.90, P < 0.0001, diet history; r(s)=0.79, P=0.0005, food records) but was not associated with age, sex, BMI or body fat. Range in number of recorded dinner foods correlated positively with energy expenditure (r(s)=0.63, P=0.01) and degree of misreporting (r(s)=0.71, P=0.003, diet history; r(s)=0.63, P=0.01, food records). Variation in energy intake at dinner and over the whole day identified by the food records correlated positively with energy expenditure (r=0.58, P = 0.02) and misreporting on the diet history (r=0.62, P=0.01). Conclusions: Subjects who are highly active or who have variable dietary and exercise behaviour may be less accurate in reporting dietary intake. Our findings indicate that it may be necessary to screen for these characteristics in studies where accuracy of reporting at an individual level is critical. Sponsorship: The study was supported in part by Australian Research Council funds made available through the University of Wollongong.

In vitro antibacterial activity of a 7-O-beta-D-glucopyranosyl-nutanocoumarin from Chaptalia nutans (Asteraceae)

Ethanolic crude extracts from the roots of Chaptalia nutans, traditionally used in Brazilian folk medicine, were screened against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa by using the disk diffusion test technique. S. aureus with 14 mm inhibition zone was considered susceptible. E. coli and P. aeruginosa without such a zone were considered resistant. As a result of this finding, the ethanolic crude extract was fractionated on silica gel column chromatography into five fractions. The ethyl acetate fraction was active against S. aureus and Bacillus subtilis. Further column chromatography separation of the ethyl acetate fraction afforded 30 fractions, which were assayed against S. aureus. Fractions 16 and 17 showed inhibition zones with S. aureus, indicating the presence of active compounds, and were subjected to purification by repeated preparative thin layer chromatography. The pure compound 7-O-beta-D-glucopyranosyl-nutanocoumarin inhibited B. subtilis and S. aureus at concentrations of 62.5 µg/ml and 125 µg/ml, respectively. The antibacterial property of C. nutans appears to have justified its use for the treatment of wounds, which are contaminated through bacterial infections.
