The esophagus and mouth tumors are very frequent malignancies worldwide. Lipopolysaccharides (LPS) are capable of regulating gene expression of pro-inflammatory cytokines by binding to toll-like receptor 4 (TLR4). Recent studies show that LPS can increase the migration ability of human esophageal cancer cell line HKESC-2 by increasing its adhesion properties. However, the effect of LPS has not been tested on viability of human esophageal and oral cancer cells. This study aimed to determine the action of LPS on the cell proliferation and viability in OE19 (adenocarcinoma) and OE21 (squamous carcinoma) cell lines, representative of human esophageal cancer, and HN30 cell line, representative of human oral carcinoma. LPS was used as treatment to OE19 and OE21 cells, and PgLPS (Porphyromonasgingivalis lipopolysaccharide) to HN30 cells. Viability was assessed by MTT assay and proliferation by cell counting. TLR4 expression was evaluated by real-time PCR. LPS at higher concentrations decreased significantly cell viability in both cell lines, adenocarcinoma (OE19) and squamous esophageal carcinoma (OE21) at different times of treatment. In addition, both cell lines, OE19 and OE21, expressed TLR4 receptor. Taken together, our data demonstrated that LPS at high concentrations might contribute to tumor death, in agreement with previously data.

Resumo Para descrever o perfil de consumo de nutrientes e verificar a sua associação com as variáveis sociodemográficas e de saúde, desenvolveu-se um estudo transversal, de base populacional em uma amostra aleatória de 427 idosos residentes em Porto Alegre, Brasil. O consumo alimentar foi avaliado através do Inquérito Recordatório de 24 Horas e Investigação da História Dietética. Dos idosos entrevistados, 70% eram mulheres; 48,5% possuíam entre 60 e 69 anos; 68,8% possuíam menos de 8 anos de escolaridade; 39,0%, renda familiar entre 2 e 5 salários mínimos; e 58,4% não praticava exercício físico. A hipertensão foi a doença mais prevalente, e 54,9% dos idosos estavam abaixo do peso. Os homens consumiam mais calorias, proteínas, fibras, minerais e vitaminas do que as mulheres. O consumo de carboidrato e cálcio aumentou conforme o avanço da idade, assim como diminuiu a ingestão de zinco. A prática de exercício físico elevou o consumo de calorias, magnésio, potássio e fósforo. Quanto maior a escolaridade, maior é o consumo de vitaminas B6 e B12; quanto maior a renda familiar, maior o consumo de vitamina B6 e ácido fólico. Os resultados demonstram que há deficiências nutricionais na alimentação diária da nossa população de idosos, principalmente entre as mulheres e os indivíduos acima de 80 anos.

Abstract A cross-sectional, population-based study was conducted on a random sample of 427 elderly individuals living in Porto Alegre, Brazil, to establish the nutrient consumption profile and verify its association with sociodemographic and health variables. Dietary intake was assessed using the 24-hour Food Recall Survey and the Dietetic Research Investigation technique. Seventy percent of the elderly respondents were women: 48.5% were between 60 and 69 years old; 68.8% had less than 8 years of schooling; 39% had a family income of between 2 and 5 minimum wages and 58.4% took no physical exercise. Hypertension was the most prevalent disease among the elderly and 54.9% were underweight. Men consumed more calories, protein, fiber, minerals and vitamins than women. Carbohydrate and calcium intake increases with advancing age, while zinc intake decreases. Physical exercise increased the intake of calories, magnesium, potassium and phosphorus. The higher the schooling the greater the intake of vitamins B6 and B12; the higher the family income, the greater the consumption of vitamin B6 and folic acid. The results show that there are nutritional deficiencies in the daily diet of the Brazilian elderly population, especially among women and individuals over 80 years of age.

ResumoEste estudo objetivou analisar a prevalência do uso de anti-inflamatórios e analgésicos em idosos da Estratégia Saúde da Família de Porto Alegre-RS, bem como investigar fatores associados: dados sociodemográficos e de saúde; uso contínuo ou se necessário da medicação; indicação médica ou automedicação. A coleta de dados ocorreu entre março de 2011 e dezembro de 2012. Os agentes de saúde comunitários aplicaram um questionário com dados sociodemográficos, de saúde e uso de medicamentos. Foram estudados os anti-inflamatórios não esteroidais, glicocorticoides, analgésicos não opioides e opioides de uso oral. Foram incluídos 758 idosos e o uso de anti-inflamatórios e analgésicos era feito por 28,8%. O paracetamol e o ibuprofeno foram os mais utilizados. No que diz respeito à autopercepção de saúde, quanto pior a saúde relatada, maior o uso da terapêutica (p<0,001). A doença hepática e artrose/artrite/reumatismo mostraram estar associadas ao uso de anti-inflamatórios e analgésicos (p<0,001). A prevalência de uso de anti-inflamatórios e analgésicos foi considerada moderada quando comparada a estudos prévios (28,8%). Além disso, a maioria dos idosos fazia uso desses medicamentos quando era preciso, provavelmente porque sentia dores leves a moderadas, não sendo necessário o uso contínuo da medicação ou também por sofrer com os efeitos adversos desses medicamentos, optando por usá-los esporadicamente.

AbstractThe aim of this study was to analyze the prevalence of the use of anti-inflammatory and analgesic drugs among elderly persons from the Family Health Program in Porto Alegre, Rio Grande do Sul, and investigate associated factors such as sociodemographic and health data; continuous or as needed use of drug, drug used subject to medical prescription or self-medicated. Data collection occurred between March 2011 and December 2012. Community health workers applied a questionnaire relating to sociodemographic and health data and medication use. Non-steroidal anti-inflammatory drugs, glucocorticoids, non-opioid analgesics and opioids were evaluated. A total of 758 elderly persons were included and anti-inflammatory and analgesic drugs were used by 28.8% of the population. Acetaminophen and ibuprofen were the most frequently used drugs. Regarding self-perception of health, the worse the perception of health, the greater was the use of therapy (p<0.001). Liver disease and osteoarthritis/arthritis/rheumatism were found to be associated with anti-inflammatory and analgesic use (p<0.001). The prevalence of anti-inflammatory and analgesic use was considered moderate when compared to previous studies (28.8%). In addition, most of the elderly persons used the drugs when only needed, most probably due to feeling minor to moderate pain or because they had suffered the adverse effects of these medications in the past and so chose to use them sporadically.

OBJECTIVE: The aims of this study were to analyze the hematological parameters, the prevalence of anemia and the association between anemia and socioeconomic conditions in an elderly community-based population. METHODS: A population-based study was performed as part of the Multidimensional Study of the Elderly in Porto Alegre, Brazil (EMIPOA). An initial total of 1058 community residents aged 60 years and older were interviewed. Of these, 392 agreed to have a physical evaluation and a blood sample was taken from each. The hematological parameters analyzed in the blood samples included the hemoglobin concentration, mean cell volume (MCV), mean corpuscular hemoglobin concentration (MCHC) and red cell distribution width (RDW). The association between the variables and the diagnosis of anemia was assessed using the chi-squared test and a multiple logistic regression model. RESULTS: The overall prevalence of anemia was 12.8%. Anemia was present in 13.7% of women and in 10.4% of men. Normocytic normochromic anemia without anisocytosis was the most common type of anemia (46%). The assessment of erythrocyte morphology showed significant differences between anemic and non-anemic individuals (microcytosis = 12% vs. 1.5%, hypochromia = 40% vs. 8.8%, and anisocytosis = 26% vs. 7%). In the analysis of socioeconomic conditions, significant differences were found in respect to age and race. CONCLUSION: The prevalence of anemia increases with age and is associated with race, microcytosis, hypochromia and anisocytosis. Anemia is not a condition that should be associated only with the aging process, as it may be due to pathological conditions that occur most frequently in this age group. As a result, a diagnosis of anemia warrants adequate clinical attention.

OBJECTIVE: This study aims to analyze pharmacological interactions among drugs taken by elderly patients and their age and gender differences in a population from Porto Alegre, Brazil. METHODS: We retrospectively analyzed the database provided by the Institute of Geriatric and Gerontology, Porto Alegre, Brazil. The database was composed of 438 elderly and includes information about the patients' disease, therapy regimens, utilized drugs. All drugs reported by the elderly patients were classified using the Anatomical Therapeutic and Chemical Classification System. The drug-drug interactions and their severity were assessed using the Micromedex® Healthcare Series. RESULTS: Of the 438 elderly patients in the data base, 376 (85.8%) used pharmacotherapy, 274 were female, and 90.4% of females used drugs. The average number of drugs used by each individual younger than 80 years was 3.2±2.6. Women younger than 80 years old used more drugs than men in the same age group whereas men older than 80 years increased their use of drugs in relation to other age groups. Therefore, 32.6% of men and 49.2% of women described at least one interaction, and 8.1% of men and 10.6% of women described four or more potential drug-drug interactions. Two-thirds of drug-drug interactions were moderate in both genders, and most of them involved angiotensin-converting enzyme inhibitor, non-steroidal anti-inflammatory, loop and thiazide diuretics, and β-blockers. CONCLUSION: Elderly patients should be closely monitored, based on drug class, gender, age group and nutritional status.

OBJETIVO: Descrever o uso de medicamentos que atuam no sistema nervoso central (SNC) e identificar as possíveis interações mais frequentes com esses medicamentos em idosos do sul do Brasil. MÉTODOS: Estudo de base populacional, transversal e observacional, realizado durante 2006-2007. Quatrocentos e oitenta idosos de ambos os sexos foram randomizados e entrevistados. Foram utilizados um questionário farmacoterapêutico validado e o programa Micromedex® Healthcare Series para analisar as potenciais interações com os medicamentos. Foi utilizada uma escala para descrever a gravidade das interações nas categorias de "leve", "moderada" e "grave". RESULTADOS: A população idosa, moradora do sul do Brasil, que utilizava medicamentos para o SNC, era formada por 98 pacientes, 75,5% mulheres e 25,5% homens. Destes pacientes, 32,0% apresentaram interações farmacológicas graves ou moderadas relacionadas com a utilização de outros medicamentos. Alprazolam e Imipramina, usados pela população, apresentaram riscos de potenciais interações com tabaco. Foram encontradas vinte potenciais interações moderadas medicamento/etanol. As potenciais interações medicamento/cafeína foram classificadas como leves. CONCLUSÃO: Os pacientes idosos deveriam ser rigorosamente monitorizados, e ainda, é necessário advertir quanto às potenciais interações de medicamentos que atuam no SNC com outros medicamentos, etanol e tabaco.

OBJECTIVE: To describe the use of CNS drugs and to identify the most frequently observed potential drug interactions in the elderly living in Southern Brazil. METHODS: A population-based, transversal and observational study was carried out during 2006-2007. Four hundred and eighty elderly individuals of both genders were randomly recruited and interviewed. A validated pharmacotherapeutic questionnaire and the Micromedex® Healthcare Series were utilized to analyze potential drug interactions. A severity rating scale employing the categories of "mild", "moderate" and "severe" was used to describe the interactions. RESULTS: A population of elderly living in Southern Brazil was interviewed and 98 reported using CNS drugs, 74.5% female and 25.5% male. Out of these patients, 32.0% reported severe or moderate pharmacological interactions related to the use of other drugs. Alprazolam and imipramine were reported to potentially interact with tobacco. Twenty potential moderate drug/ethanol interactions were found. The potential drug/caffeine interactions were classified as mild on the severity scale. CONCLUSION: Elderly being prescribed drugs that act on the CNS should be closely monitored, and furthermore, should be warned against potential drug-drug, drug-ethanol, and drug-tobacco interactions.

Polifarmácia e falta de adesão à prescrição médica são problemas freqüentes na terapêutica farmacológica de idosos que podem prejudicar o resultado do seu tratamento. Realizou-se um estudo transversal exploratório e quantitativo em base populacional para levantar a freqüência de idosos aderentes e avaliar se a polifarmácia interfere na adesão. A pesquisa foi realizada com 466 idosos de Porto Alegre, RS. Os instrumentos foram aplicados por entrevista individual. A freqüência de idosos aderentes foi de 173 (37,1%) e maior entre os que utilizavam menos fármacos. Os resultados encontrados sugerem a implementação de programas educacionais para auxiliar os idosos no seguimento à terapêutica farmacológica.

Polipharmacy and medication non-adherence are problems faced frequently in the treatment of elderly patients. An exploratory cross-sectional study and quantitative approach were conducted to assess the frequency of treatment-adherence in elderly and how polipharmacy can affect adherence. Four hundred and sixty six elderly answered a questionnaire in Porto Alegre, RS in individual interviews. The adherence frequency found was 173 (37.1%) and was higher among those, who use less medication. These results indicate the need for implementing educational programs for the elderly in order to help them to follow their drug therapy.
