Condições socioeconômicas e câncer de cabeça e pescoço: uma revisão sistemática de literatura

O presente estudo teve como objetivo descrever as principais características dos estudos epidemiológicos que investigaram a associação entre condições socioeconômicas e câncer de cabeça e pescoço. Foram pesquisadas as bases de dados Medline (Literatura Internacional em Ciências), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Scielo (Scientific Electronic Library Online), além de referências citadas nos artigos obtidos a partir da busca primária nessas bases. O período de publicação considerado englobou 38 anos (1970-2007) e a análise restringiu-se aos artigos em espanhol, inglês ou português. Foram selecionados 25 estudos, 15 com delineamento caso-controle, quatro ecológicos e seis que mesclaram informações de bases de dados oficiais, como censos e registros de câncer ou de óbitos. A maior parte das pesquisas reportou associação entre piores condições socioeconômicas e câncer de cabeça e pescoço. Os indicadores mais empregados foram a ocupação e a escolaridade. Poucos estudos investigaram mediação, procurando evidenciar quais os fatores proximais operam na associação investigada. Pesquisas adicionais, com critérios uniformes para proceder aos ajustes nos modelos de regressão e amostra suficiente, são necessárias para investigar essa dimensão.

O Jornal da Paulista: a configuração de um meio de divulgação universitária numa perspectiva histórica

Este artigo, decorrência da pesquisa de mestrado realizada no programa do Centro de Desenvolvimento do Ensino Superior em Saúde da Universidade Federal de São Paulo (2007), tem como objetivo apresentar a descrição e a análise da trajetória histórica do Jornal da Paulista, jornal universitário que surgiu na Escola Paulista de Medicina em 1987 e que circulou até 2003, quando esta já havia se transformado em universidade. Partindo do referencial teórico do semiólogo Eric Landowiski, a trajetória do Jornal da Paulista foi dividida em três fases. Na primeira, o jornal foi compreendido como uma publicação direcionada à necessidade de comunicação interna e de divulgação institucional; na segunda fase ocorreu uma intensificação na publicação de matérias de divulgação científica; e a terceira fase foi avaliada como um momento de envolvimento pleno do jornal com a comunicação pública das ciências da saúde. Apontamos que o JP constituiu-se preponderantemente como um veículo de divulgação científica das ciências da saúde.

Situação de mendicância, trabalho precoce e prostituição infantil envolvendo crianças e adolescentes em Londrina, Estado do Paraná - 2006

Nas últimas décadas, a importância da infância e adolescência e a necessidade de proteção deste grupo têm mobilizado sociedades no sentido de notificarem aos órgãos competentes situações de risco em que figuram crianças e adolescentes. A pesquisa, de natureza descritiva, objetivou estudar as circunstâncias da mendicância, trabalho e prostituição infantil envolvendo menores de 15 anos residentes em Londrina, Estado do Paraná, notificadas aos Conselhos Tutelares, em 2006. Os dados foram coletados nos prontuários dos Conselhos Tutelares, utilizando-se formulário com questões fechadas, e analisados pelo programa Epi Info. Foram estudados 27 casos, 55,6 por cento de meninas e 44,4 por cento de meninos, com idades de 11 anos para os meninos (33,3 por cento) e oito anos para as meninas (26,7 por cento). Os principais agressores foram a mãe (37,0 por cento) e o pai (37,0 por cento), com idade predominante de 30 a 34 anos para os homens (58,3 por cento) e de 20 a 24 para as mulheres (40,0 por cento). Entre os meninos, destacou-se trabalho infantil (58,3 por cento) e mendicância (41,7 por cento). Entre as meninas, mendicância (53,3 por cento), prostituição (33,3 por cento) e trabalho infantil (13,3 por cento). É preciso ressaltar a necessidade de que a sociedade como um todo combata esses tipos de violência tão desastrosos para a criança e o adolescente. Deve ser prioritária a participação de todos os segmentos sociais, instâncias executivas e legislativas a fim de formular, acompanhar e avaliar políticas voltadas para a redução do trabalho infantil, da problemática das crianças de rua e, principalmente, da exploração sexual de crianças e adolescentes

Evaluation of three brands of drug interaction software for use in intensive care units

Objective To evaluate drug interaction software programs and determine their accuracy in identifying drug-drug interactions that may occur in intensive care units. Setting The study was developed in Brazil. Method Drug interaction software programs were identified through a bibliographic search in PUBMED and in LILACS (database related to the health sciences published in Latin American and Caribbean countries). The programs` sensitivity, specificity, and positive and negative predictive values were determined to assess their accuracy in detecting drug-drug interactions. The accuracy of the software programs identified was determined using 100 clinically important interactions and 100 clinically unimportant ones. Stockley`s Drug Interactions 8th edition was employed as the gold standard in the identification of drug-drug interaction. Main outcome Sensitivity, specificity, positive and negative predictive values. Results The programs studied were: Drug Interaction Checker (DIC), Drug-Reax (DR), and Lexi-Interact (LI). DR displayed the highest sensitivity (0.88) and DIC showed the lowest (0.69). A close similarity was observed among the programs regarding specificity (0.88-0.92) and positive predictive values (0.88-0.89). The DIC had the lowest negative predictive value (0.75) and DR the highest (0.91). Conclusion The DR and LI programs displayed appropriate sensitivity and specificity for identifying drug-drug interactions of interest in intensive care units. Drug interaction software programs help pharmacists and health care teams in the prevention and recognition of drug-drug interactions and optimize safety and quality of care delivered in intensive care units.

Biochemistry of the Envenomation Response-a Generator Theme for Interdisciplinary Integration

The understanding of complex physiological processes requires information from many different areas of knowledge. To meet this interdisciplinary scenario, the ability of integrating and articulating information is demanded. The difficulty of such approach arises because, more often than not, information is fragmented through under graduation education in Health Sciences. Shifting from a fragmentary and deep view of many topics to joining them horizontally in a global view is not a trivial task for teachers to implement. To attain that objective we proposed a course herein described Biochemistry of the envenomation response aimed at integrating previous contents of Health Sciences courses, following international recommendations of interdisciplinary model. The contents were organized by modules with increasing topic complexity. The full understanding of the envenoming pathophysiology of each module would be attained by the integration of knowledge from different disciplines. Active-learning strategy was employed focusing concept map drawing. Evaluation was obtained by a 30-item Likert-type survey answered by ninety students; 84% of the students considered that the number of relations that they were able to establish as seen by concept maps increased throughout the course. Similarly, 98% considered that both the theme and the strategy adopted in the course contributed to develop an interdisciplinary view.

In situ gelling hexagonal phases for sustained release of an anti-addiction drug

In this study, fluid precursor formulations for subcutaneous injection and in situ formation of hexagonal phase gels upon water absorption were developed as a strategy to sustain the release of naltrexone, a drug used for treatment of drug addiction. Precursor formulations were obtained by combining BRIJ 97 with propylene glycol (PG, 5-70%, w/w). To study the phase behavior of these formulations, water was added at 10-90% (w/w), and the resulting systems were characterized by polarized light microscopy. Two precursor formulations containing BRIJ:PG at 95:5 (w/w, referred to as BRIJ-95) and at 80:20 (w/w, referred to as BRIJ-80) were chosen. Naltrexone was dissolved at 1% or suspended at 5% (w/w). Precursor formulations were transformed into hexagonal phases when water content exceeded 20%. Water uptake followed second-order kinetics, and after 2-4 h all precursor formulations were transformed into hexagonal phases. Drug release was prolonged by the precursor formulations (compared to a drug solution in PBS), and followed pseudo-first order kinetics regardless of naltrexone concentration. The release from BRIJ-80 was significantly higher than that from BRIJ-95 after 48 h. The relative safety of the precursor formulations was assessed in cultured fibroblasts. Even though BRIJ-95 was more cytotoxic than BRIJ-80, both precursor formulations were significantly less cytotoxic than sodium lauryl sulfate (considered moderate-to-severe irritant) at the same concentration (up to 50 mu g/mL). These results suggest the potential of BRIJ-based precursor formulations for sustained naltrexone release. (C) 2011 Elsevier By. All rights reserved.

Topical Delivery of Lycopene Using Microemulsions: Enhanced Skin Penetration and Tissue Antioxidant Activity

Topical delivery of lycopene is a convenient way to supplement cutaneous levels of antioxidants. In this study, lycopene was incorporated (0.05%, w/w) in two microemulsions containing BRIJ-propylene glycol (2:1, w/w, surfactant blend) but different oil phases: mono/diglycerides of capric and caprylic acids (MG) or triglycerides of the same fatty acids (TG). Microemulsions containing MG and TG were isotropic, fluid, and clear, with internal phase diameters of 27 and 52 nm, respectively. Both MG- or TG-containing microemulsions markedly increased lycopene penetration in the stratum corneum, (6- and 3.6-fold, respectively) and in viable layers of porcine ear skin 2 (from undetected to 172.6 +/- 41.1 and 103.1 +/- 7.2 ng/cm(2), respectively) compared to a control solution. To assure that lycopene delivered to the skin was active, the antioxidant activity of skin treated with MG-containing microemulsion was determined by CUPRAC assay, and found to be 10-fold higher than untreated skin. The cytotoxicity of MG-containing microemulsion in cultured fibroblasts was similar to propylene glycol (considered safe) and significantly less than of sodium lauryl sulfate (a moderate-to-severe irritant) at 1-50 mu g/mL. These results demonstrate that the MG-containing microemulsion is an efficient and safe system to increase lycopene delivery to the skin and the antioxidant activity in the tissue.

Microemulsions Containing Medium-Chain Glycerides as Transdermal Delivery Systems for Hydrophilic and Hydrophobic Drugs

We evaluated the ability of microemulsions containing medium-chain glycerides as penetration enhancers to increase the transdermal delivery of lipophilic (progesterone) and hydrophilic (adenosine) model drugs as well as the effects of an increase in surfactant blend concentration on drug transdermal delivery. Microemulsions composed of polysorbate 80, medium-chain glycerides, and propylene glycol (1:1:1, w/w/w) as surfactant blend, myvacet oil as the oily phase, and water were developed. Two microemulsions containing different concentrations of surfactant blend but similar water/oil ratios were chosen; ME-lo contained a smaller concentration of surfactant than ME-hi (47:20:33 and 63:14:23 surfactant/oil/water, w/w/w). Although in vitro progesterone and adenosine release from ME-lo and ME-hi was similar, their transdermal delivery was differently affected. ME-lo significantly increased the flux of progesterone and adenosine delivered across porcine ear skin (4-fold or higher, p < 0.05) compared to progesterone solution in oil (0.05 +/- 0.01 mu g/cm(2)/h) or adenosine in water (no drug was detected in the receptor phase). The transdermal flux of adenosine, but not of progesterone, was further increased (2-fold) by ME-hi, suggesting that increases in surfactant concentration represent an interesting strategy to enhance transdermal delivery of hydrophilic, but not of lipophilic, compounds. The relative safety of the microemulsions was assessed in cultured fibroblasts. The cytotoxicity of ME-lo and ME-hi was significantly smaller than sodium lauryl sulfate (considered moderate-to-severe irritant) at same concentrations (up to 50 mu g/mL), but similar to propylene glycol (regarded as safe), suggesting the safety of these formulations.

Pre and post-natal exposure to ambient level of air pollution impairs memory of rats: the role of oxidative stress

The aims of this study were to evaluate whether air pollution during pre-natal and post-natal phases change habituation and short-term discriminative memories and if oxidants are involved in this process. As secondary objectives, it was to evaluate if the change of filtered to nonfiltered environment could protect the cortex of rats against oxidative stress as well as to modify the behavior of these animals. Wistar, male rats were divided into four groups (n = 12/group): pre and post-natal exposure until adulthood to filtered air (FA); pre-natal period to nonfiltered air (NFA-FA); until (21st post-natal day) and post-natal to filtered air until adulthood (PND21); prenatal to filtered air until PND21 and post-natal to nonfiltered air until adulthood (FA-NFA); pre and post-natal to nonfiltered air (NFA). After 150 days of air pollution exposure, animals were tested in the spontaneous object recognition test to evaluate short-term discriminative and habituation memories. Rats were euthanized; blood was collected for metal determination; cortex dissected for oxidative stress evaluation. There was a significant increase in malondialdehyde (MDA) levels in the NFA group when compared to other groups (FA: 1.730 +/- 0.217; NFA-FA: 1.101 +/- 0.217; FA-NFA: 1.014 +/- 0.300; NFA: 5.978 +/- 1.920 nmol MDA/mg total proteins; p = 0.007). NFA group presented a significant decrease in short-term discriminative (FA: 0.603 +/- 0.106; NFA-FA: 0.669 +/- 0.0666; FA-NFA: 0.374 +/- 0.178; NFA: -0.00631 +/- 0.106 sec; p = 0.006) and an improvement in habituation memories when compared to other groups. Therefore, exposure to air pollution during both those periods impairs short-term discriminative memory and cortical oxidative stress may mediate this process.

The use of complementary and alternative therapies by patients with cancer

The aim of this research was to assess the prevalence and predictors of complementary and alternative therapy (CAT) use among cancer patients in Australia. A total of 1492 cancer patients attending nine major public cancer treatment centers in New South Wales, Australia, were asked to complete the Supportive Care Needs Survey. Of the 1354 consenting patients, 888 (65%) returned a completed survey. This article reports the secondary analyses of the survey data, specifically focusing on CAT use. For all cancers, 17.1% of patients were using at least one CAT. The two main demographic characteristics of CAT users were gender and age, where females were more likely to use CAT than males and that CAT use declined as age increased. Time since diagnosis was identified as the only significant clinical predictor of CAT use, where CAT use increased with time until 5 years since diagnosis. Our research shows that herbal treatments and naturopathy are the most popular CAT used by cancer patients (constituting over 30% of all CAT use recorded). The use of CAT among cancer patients is a significant issue in cancer care, especially considering the potential interactions between CAT and conventional medicines. Given that many cancer patients may not be aware of potential risks associated with these interactions it is important that oncologists and others involved in cancer patient care are informed about CAT and its use amongst their patients.

Adult language input in the early childhood educational setting

Age-related changes in the adult language addressed to children aged 2;0-4;0 years in polyadic conditions were investigated in Australian childcare centres. The language that 21 staff members addressed to these children was coded for multiple variables in the broad social categories of prosody, context, speech act and gesture. The linguistic components were coded within the categories of phonology, lexicon, morphology, syntax and referential deixis. Minimal age-related differences were found. Explanations for the similarity of the adult language input across the age groups within the early childhood educational environment, will be discussed

RE: Does Snus use have a harm reduction effect in Sweden?

Eletter to Tobacco Control in response to an eletter published in the same journal about whether snus (Swedish moist oral snuff) was responsible for a decline in smoking prevalence among men in Sweden.

The prospects for tobacco harm reduction

Tobacco harm reduction (THR) policies aim to reduce the prevalence of tobacco-related harm by encouraging smokers who are unable or unwilling to quit to adopt less harmful ways of obtaining nicotine, such as pharmaceutical nicotine and oral tobacco snuff. Proponents of THR argue that the effects of tobacco control policies have reduced smoking as much as they reasonably can and that we can best reduce tobacco-related harm by encouraging smokers to use these methods, which substantially reduce the health risks of smoking. Critics argue that THR policies will undermine the two traditional tobacco control goals of preventing the uptake of smoking by young people and encouraging smokers to quit. I assess the main arguments and evidence advanced for and against THR.
