Consumption of sugar-sweetened soft drinks and risk of metabolic syndrome and its components: results of the ELSA-Brasil study (2008-2010 and 2012-2014).

AIM: To estimate the association between consumption of sugar-sweetened soft drinks and unsweetened fruit juice with metabolic syndrome (MetS) and its components in participants of the Brazilian Longitudinal Adult Health Study (ELSA-Brasil) after 4 years of follow-up. METHODS: We used data from ELSA-Brasil cohort (N = 15,105). The sample consisted of 6,124 civil servants free of the MetS at baseline (35 to 74 years, both sexes). The consumption of sugar-sweetened soft drinks and unsweetened fruit juice was estimated by a food frequency questionnaire previously validated. The outcome was MetS and its components (Joint Interim Statement criteria). To test the association between beverage consumption at baseline (2008-2010) and MetS and its components at follow-up (2012-2014), we used Poisson regression models with robust variance adjusting for potential confounders. RESULTS: After 4-year follow-up, the higher consumption of sugar-sweetened soft drinks (≥ 1 serving/day = 250 mL/day) increased the relative risk of MetS (RR = 1.22; 95% CI 1.04-1.45), high fasting glucose (RR = 1.23; 95% CI 1.01-1.48), and high blood pressure (RR = 1.23; 95% CI 1.00-1.54). Moderate consumption of this beverage (0.4 to < 1 serving/day) increased the relative risk of high waist circumference (WC) (RR = 1.21; 95% CI 1.02-1.42). After adjustment for confounding variables, the consumption of unsweetened fruit juice was not associated with the MetS and its components. CONCLUSION: Higher sugar-sweetened soft drinks consumption was associated with a higher risk relative of MetS, high fasting glucose, and high blood pressure, while moderate consumption of this beverage increased the relative risk of high WC in Brazilian adults.

Association of sleep disturbances with sarcopenia and its defining components: the ELSA-Brasil study.

Sarcopenia and sleep problems share common physiopathology. We aimed to investigate the association of sleep disturbances with sarcopenia and its defining components in Brazilian middle-aged and older adults. In this cross-sectional analysis of the second wave of the ELSA-Brasil study, we included data from 7948 participants aged 50 years and older. Muscle mass was evaluated by bioelectrical impedance analysis and muscle strength by hand-grip strength. Sarcopenia was defined according to the Foundation for the National Institutes of Health criteria. Sleep duration and insomnia complaint were self-reported. Short sleep duration was considered as ≤6 h/night and long sleep duration as >8 h/night. High risk of obstructive sleep apnea (OSA) was assessed using the STOP-Bang questionnaire. Possible confounders included socio-demographic characteristics, lifestyle, clinical comorbidities, and use of sedatives and hypnotics. The frequencies of sarcopenia, low muscle mass, and low muscle strength were 1.6, 21.1, and 4.1%, respectively. After adjustment for possible confounders, high risk of OSA was associated with low muscle mass (OR=2.17, 95%CI: 1.92-2.45). Among obese participants, high risk of OSA was associated with low muscle strength (OR=1.68, 95%CI: 1.07-2.64). However, neither short nor long sleep duration or frequent insomnia complaint were associated with sarcopenia or its defining components. In conclusion, high risk of OSA was associated with low muscle mass in the whole sample and with low muscle strength among obese participants. Future studies are needed to clarify the temporal relationship between both conditions.

Highly porous multiwalled carbon nanotube buckypaper using electrospun polyacrylonitrile nanofiber as a sacrificial material.

Polyacrylonitrile (PAN) was solubilized in N,N-dimethyl formamide (DMF) and the electrospinning process has been employed to obtain PAN nanofibers (PF). Multiwalled carbon nanotubes (MWCNT) were dispersed with the aid of Triton X-100 surfactant and subsequently centrifugated. Buckypapers (BP/PF) were prepared by vacuum filtration procedure of MWCNT suspension supernatant stacking four PF layers over a nylon membrane. The PF removal was carried out by immersing the BP/PF system in DMF and removal periods of 10 and 30 min were evaluated. Scanning electron microscopy (SEM) has not shown any PAN residue in the MWCNT network resulting in highly porous BP. However, by Fourier transform infrared spectroscopy (FT-IR) a PAN band was found around of 2243 cm-1 corresponding to nitrile group (C≡N). Besides, PAN leftover was evidenced by thermogravimetric analysis (TGA), high-resolution transmission electron microscopy (HR-TEM), electrical characterization through four-point probe, nitrogen adsorption at 77 K, and X-ray diffraction (XRD).

Relationship between heart rate variability and subclinical thyroid disorders of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

The association between subclinical thyroid dysfunctions and autonomic modulation changes has been described by many studies with conflicting results. We aimed to analyze the association between subclinical hyperthyroidism (SCHyper), subclinical hypothyroidism (SCHypo), and heart rate variability (HRV) using the baseline from ELSA-Brasil. SCHyper and SCHypo were classified by use of medication to treat thyroid disorders, thyrotropin levels respectively above and under the reference range, and normal free thyroxine levels. For HRV, the participants underwent 10 min in supine position and the R-R intervals of the final 5 min were selected for analysis. We first used linear regression models to report crude data and then, multivariate adjustment for sociodemographic (age, sex, and race) and cardiovascular risk factors (hypertension, dyslipidemia, diabetes, smoking, body mass index, use of alcohol, and leisure physical activity) using the euthyroid group as reference. From 9270 subjects (median age, 50; interquartile range: 44-56), 8623 (93.0%) were classified as euthyroid, 136 (1.5%) as SCHyper, and 511 (5.5%) as SCHypo. Compared to euthyroid subjects, SCHyper participants presented significantly higher heart rate (68.8 vs 66.5 for euthyroidism, P=0.007) and shorter R-R intervals (871.4 vs 901.6, P=0.007). Although SCHyper was associated with lower standard deviation of NN interval (SDNN) (ß: -0.070; 95% confidence interval (95%CI): -0.014 to -0.009) and low-frequency (LF) (ß: -0.242, 95%CI: -0.426 to -0.058) compared to the euthyroid group, these differences lost significance after multivariate adjustment for confounders. No significant differences were found for HRV in SCHypo. No association was found between HRV and SCHyper or SCHypo compared to euthyroid subjects in this sample of apparently healthy subjects.

No significant differences were found for HRV in SCHypo. No association was found between HRV and SCHyper or SCHypo compared to euthyroid subjects in this sample of apparently healthy subjects.

Mortality rate after open Roux-in-Y gastric bypass: a 10-year follow-up

The prevalence of obesity has increased to epidemic status worldwide. Thousands of morbidly obese individuals undergo bariatric surgery for sustained weight loss; however, mid- and long-term outcomes of this surgery are still uncertain. Our objective was to estimate the 10-year mortality rate, and determine risk factors associated with death in young morbidly obese adults who underwent bariatric surgery. All patients who underwent open Roux-in-Y gastric bypass surgery between 2001 and 2010, covered by an insurance company, were analyzed to determine possible associations between risk factors present at the time of surgery and deaths related and unrelated to the surgery. Among the 4344 patients included in the study, 79% were female with a median age of 34.9 years and median body mass index (BMI) of 42 kg/m2. The 30-day and 10-year mortality rates were 0.55 and 3.34%, respectively, and 53.7% of deaths were related to early or late complications following bariatric surgery. Among these, 42.7% of the deaths were due to sepsis and 24.3% to cardiovascular complications. Male gender, age ≥50 years, BMI ≥50 kg/m2, and hypertension significantly increased the hazard for all deaths (P<0.001). Age ≥50 years, BMI ≥50 kg/m2, and surgeon inexperience elevated the hazard of death from causes related to surgery. Male gender and age ≥50 years were the factors associated with increased mortality from death not related to surgery. The overall risk of death after bariatric surgery was quite low, and half of the deaths were related to the surgery. Older patients and superobese patients were at greater risk of surgery-related deaths, as were patients operated on by less experienced surgeons.

Atividade anti-helmíntica de plantas nativas do continente americano: uma revisão / Anthelmintic activity of native American plants: a review

O presente trabalho faz uma revisão de plantas nativas do continente americano com atividade anti-helmíntica com a finalidade de subsidiar pesquisas e o desenvolvimento de novos medicamentos na área de produtos naturais. Na literatura, foram citadas 22 famílias de plantas, tais como: Moraceae, Asteraceae e Cucurbitaceae, e estudadas cerca de 35 espécies, como a Ficus sp, Cucurbita máxima, e Ruta graveolens, usadas por sua alegada atividade anti-helmíntica. Destas espécies, 26 foram ativas contra alguns helmintos: Strongyloides stercolaris, Ancylostomidae, Trichostrongylus sp, Capillaria sp, Ascaris lumbricoides, Taenia saginata, Haemonchus contortus, e Hymenolepsis diminuta. Foi verificado maior número de estudos com parasitas de animais, possivelmente devido ao desenvolvimento de resistência dos helmintos aos tratamentos convencionais disponíveis.

This paper is a review of native American plants showing anthelmintic activity in order to give support to research and development of new drugs in the field of natural products. In the literature, 22 plant families were cited, such as: Moraceae, Asteraceae and Cucurbitaceae, and around 35 species were studied, including Ficus sp, Cucurbita maxima and Ruta graveolens, used for their putative anthelmintic activity. From these species, 26 were active against some helminthes: Strongyloides stercolaris, Ancylostomidae, Trichostrongylus sp, Capillaria sp, Ascaris lumbricoides, Taenia saginata, Haemonchus contortus and Hymenolepsis diminuta. Data indicated a larger number of studies with animal parasites, probably due to the resistance of these helminthes to the conventional treatments available.

Possibilidades terapêuticas e risco toxicológico de Jatropha gossypiifolia L: uma revisão narrativa / Therapeutic possibilities and toxicological risk of Jatropha gossypiifolia L: a narrative review

A espécie Jatropha gossypiifolia L. (Euphorbiaceae), popularmente conhecida como pião-roxo, entre tantos outros nomes, é um bom exemplo do tênue limiar que separa o efeito terapêutico do tóxico. Apesar de ser classicamente conhecida como planta tóxica possui usos na medicina popular. Alguns desses efeitos têm sido comprovados em estudos experimentais, como os de antimicrobiano, antineoplásico, cicatrizante e hipotensor, sendo possivelmente explicados pela presença de substâncias como alcalóides, terpenóides, flavonóides, lignanas e taninos. Esta revisão aborda aspectos importantes, com ênfase na toxicidade crônica dessa espécie, de modo a servir de fonte de informação aos interessados em avaliar a relação risco/benefício do uso terapêutico de Jatropha gossypiifolia L.

The species Jatropha gossypiifolia L. (Euphorbiaceae), popularly known as bellyache bush, among several other names, is an important example of the tenuous threshold that separates the therapeutic from the toxic effect. Although traditionally known as a toxic plant, it has been used in folk medicine. Some of its effects have been proved by experimental studies as antimicrobial, antineoplastic, healing and hypotensive, likely explained by the presence of substances such as alkaloids, terpenoids, flavonoids, lignans and tannins. This review deals with important aspects, focusing on the chronic toxicity of this species, in order to serve as an information source for those interested in evaluating the risk-benefit ratio of the therapeutic use of Jatropha gossypiifolia L.

Análise dos componentes da síndrome metabólica antes e após a suplementação dietética com farinha da casca do maracujá, em pacientes diabéticos / Analysis of components of metabolic syndrome before and after dietary supplementation with flour passion fruit peel in diabetic patients

A Síndrome Metabólica (SM) é caracterizada pela reunião de vários fatores de risco para doenças cardiovasculares (DCV): obesidade central (OC), hipertrigliceridemia, hipercolesterolemia e hipertensão arterial. Tendo conhecimento de que, além da terapia medicamentosa atual, o uso de fibras dietéticas tem demonstrado ser uma alternativa na redução dos fatores de riscos para as DCV. Este trabalho objetivou avaliar o efeito da farinha da casca do maracujá amarelo (Passiflora edulis f. flavicarpa Deg.) rica em fibra solúvel nos componentes da SM. Foi realizado ensaio clínico de fase II com 43 voluntários com idade entre 57 e 73 anos, de ambos os gêneros. Durante 60 dias, os participantes diariamente fizeram uso de 30 g do produto estudado e em todos eles foras determinados antes e após a suplementação com a farinha: glicose, hemoglobina glicada, frações lipídicas, além da antropometria e pressão arterial. Após a suplementação, existiu uma diferença significante (p,0,05) nos valores de OC, pressão arterial, glicose, hemoglobina glicada e triglicerídeos. Em relação ao colesterol total e LDL-c, não foram observadasa alterações estatisticamente significantes, enquanto o HDL-c apresentou aumento em suas concentrações de maneira significativa. Os resultados mostraram que a suplementação utilizada exerceu efeito positivo na maioria dos componentes da SM, sugerindo seu uso como terapia complementar dos tratamentos convencionais.

Natriuretic peptides: linking heart and adipose tissue in obesity and related conditions--a systematic review.

The objective of this study was to investigate the association between natriuretic peptides, obesity and related comorbidities. A systematic review of the English language literature from 1996 to 2008 was performed with Pubmed/MEDLINE and the ISI Web of Knowledge. 'Natriuretic peptides', 'atrial natriuretic factor', 'brain natriuretic peptide', 'obesity', 'body mass index', 'lipolysis' and 'adipose tissue' were used as Mesh terms. We also conducted a handle search among the references of the original articles selected. Finally, seventy-five studies were considered eligible for inclusion in the review. Natriuretic peptides are widely known as body homeostasis regulators. Recently, their action as lipolytic agents has been identified. Obese patients, especially those with hypertension and metabolic risk factors, have reduced plasma levels of natriuretic peptides. Whether this precedes or follows obesity and its complications remains undefined. The lipolytic effect of natriuretic peptides indicates that they may be involved in the pathophysiology of obesity. In general, studies with obese patients support paradoxical reduced levels of natriuretic peptides. However, the selection of subjects and classification of obesity and heart failure varied among the reviewed studies, rendering comparison unreliable.

Plants of the American continent with antiulcer activity.

Peptic ulcer is a chronic and appalling disease. Today, it is dominant among the diseases that affect the world's population. The principal factors causing this disease are inadequate dietetic habits, prolonged use of non-steroidal anti-inflammatory drugs, stress and infection by Helicobacter pylori, in addition to other factors of genetic origin. The present work is a literature survey of plant extracts from the American continent that have been reported to show antiulcer activity. This review refers to 58 plants with their families, parts used, type of extract used, model bioassays and their activity. This work intends to aid the researchers in the study of natural products appropriate to the treatment of stomach and intestinal diseases, in general, and peptic ulcer in particular.

De todas as bactérias isoladas, as Gram-positivas e as Gram-negativas compreenderam 91,2 por cento e 8,8 por cento, respectivamente. Dentre as Gram-positivas, a mais freqüente foi Bacillus sp.(31,2 por cento) e a menos, Staphylococcus saprophyticcus (3,0 por cento). Quanto às bactérias Gram-negativas, a mais encontrada foi Escherichia coli (50,1 por cento) e a menos, Serratia liquefaciens (6,2 por cento)

Estudo sobre o uso de plantas medicinais em crianças hospitalizadas da cidade de João Pessoa: riscos e benefícios / Survey on the use medicinal plants in children hospitalized in the city of João Pessoa city: risks and benefits

Trata-se de um estudo com abordagem quantitativa, com o objetivo de investigar o uso de plantas medicinais em crianças na faixa etária de zero a 12 anos internadas no Hospital Infantil Arlinda Marques, da cidade de João Pessoa (PB), entre agosto de 2000 a junho de 2001. Um roteiro de entrevista semi-estruturado foi empregado junto aos 132 acompanhantes das crianças para a obtenção dos dados. Os resultados evidenciaram que as doenças que mais acometeram as crianças foram: 1) pneumonia (26 por cento), 2) infecções intestinais (13 por cento), 3) anemia (8 por cento), 4) afecções renais (7 por cento). Cerca de 27,3 por cento dos acompanhantes usaram plantas medicinais em suas crianças antes de procurarem o Serviço Hospitalar e 41,7 por cento associaram plantas com alguma medicação. Diante destes resultados pode-se concluir que a utilização de plantas medicinais em crianças para o tratamento de doenças possui seus riscos e benefícios que precisam ser avaliados pelos profissionais de saúde.

The aim of this study is to investigate the use of medicinal plants in children of zero to 12 years hospitalized in the "Hospital Infantil Arlinda Marques", City of João Pessoa, State of Paraíba, Brazil between August 2000 and June 2001. For the collection of the data a half-structuralized script interview was applied to 132 children's companions. The results evidenced that the illnesses which mostly affected the children were: 1) pneumonia (26 percent), 2) infections of the intestines (13 percent), 3) anemia (8 percent), 4) kidneys illnesses (7 percent). About 27,3 percent of the companions had used medicinal plants in the children before going to the hospital service; 41,7 percent had associated plants with some medicines. Based on this, it can be concluded that the use of medicinal plants in children for the treatment of illnesses has its risks and benefits that need to be evaluated by health professionals.

Anorectic and behavioural effects of chronic Cissampelos sympodialis treatment in female and male rats.

Male and female rats were treated daily for 13 weeks with an ethanol extract of Cissampelos sympodialis leaves (9, 45 and 225 mg[sol ]kg). The food consumption, body weight and behavioural effects in the open-field test were evaluated by weekly monitoring. The results showed that the extract chronic treatment in female rats (45 and 225 mg[sol ]kg) reduced significantly the food intake and the body weight, and produced several alterations in the open-field test. These findings indicate that repeated oral administration of the extract may produce a sex-dependent difference in anoretic and behavioural effects.

Avaliação da adequação da publicidade de produtos naturais anunciada na Paraíba / Accuracy of information on natural products advertised in Paraíba

Considerando-se a expansão crescente do uso e comercialização de produtos naturais nos últimos anos e a preocupação com a qualidade e segurança dos produtos anunciados na mídia, buscou-se avaliar a adequação de sua publicidade em relação à legislação vigente. Com este objetivo, foi feita a coleta de 135 peças publicitárias, anunciando 690 diferentes produtos, obtidas em cinco diferentes veículos de comunicação: impressos, revistas, jornais regionais, emissoras de TV e de rádio veiculadas no município de João Pessoa/PB, no período de outubro de 2002 a outubro de 2003. O conteúdo das peças publicitárias foi analisado, considerando-se a sua adequação a Resolução de Diretoria Colegiada (RDC) número 102/2000/ANVISA, que regula a publicidade de medicamentos. Foi observado que 97,04% das peças publicitárias anunciadas na Paraíba não se encontram coerentes com a legislação brasileira, podendo promover diversos danos aos seus usuários, como o uso indiscriminado de medicamentos, a automedicação e reações adversas

Medicinal plants in the healing of dry socket in rats: microbiological and microscopic analysis.

The effectiveness of medicinal herbs as antimicrobial agents was tested on isolated microorganisms from an induced alveolitis and on alveolitis in rats. Sixteen ethanolic extracts from plants were prepared and tested. The plant materials were selected from ethnobotanic data and the best result was obtained with Schinus terebinthifolius Raddi. The activity on Enterococcus, Bacillus corineforme, Streptococcus viridans and S. beta-hemolytic was better than the one presented by the antibiotic currently used for the treatment of alveolitis. The extract of Schinus terebinthifolius Raddi has shown good wound-healing activity by histological analysis.
