Association between anthropometric markers and asthma control, quality of life and pulmonary function in adults with asthma.

BACKGROUND: The role of abdominal fat and body fat (BF) in the evaluation of nutritional status in asthma has been considered recently. The present study aimed to evaluate the association between different anthropometric markers and asthma control, pulmonary function and quality of life. A secondary objective was to determine the agreement between the anthropometric markers with respect to assessing obesity in adults with asthma. METHODS: This cross-sectional study enrolled adult asthma patients attending an outpatient asthma clinic in southern Brazil. Patients were evaluated regarding sociodemographic data, lung function, asthma control, nutritional status and health-related quality of life (Asthma Quality of Life Questionnaire; AQLQ). Nutritional status was classified by body mass index (BMI), waist circumference (WC) and BF. RESULTS: The mean (SD) age of the 198 patients was 56.2 (14.8) years. The prevalence of uncontrolled asthma among subjects who were overweight as diagnosed by their BMI was 64.6% higher than in those who were normal weight. An increase in a measure of BMI (1 kg m-2 ) decreases approximately 44-59% of symptoms, activity limitations and emotional function domains of the AQLQ, whereas an increase in a measure in WC (1 cm) decreases approximately 24-30% of the same domains. Agreement between BMI and BF was 0.566 and that between BMI and WC was 0.597 by Kendall's Tau-b test. CONCLUSIONS: The prevalence of uncontrolled asthma is greater in overweight subjects than in normal weight subjects. WC and BMI were negatively associated with symptoms, activity limitations and emotional function domains of the AQLQ. BMI appears to be sufficient to diagnose the nutritional status of subjects with asthma in this population.

DNA profiles of Salmonella spp. isolated from chicken products and from broiler and human feces

Salmonella species have been isolated from various kinds of food and are accountable for outbreaks of foodborne diseases in humans. This study aimed at identifying the similarities between the DNA profiles of Salmonella isolated from chicken feces, chicken products, and human feces in southern Brazil. Six hundred samples were collected (200 from chicken products, 200 from broiler chicken feces, and 200 from human feces) and tested for the presence of Salmonella. Isolates proven to be Salmonella compatible by biochemical and serological tests were tested by the Polymerase Chain Reaction. Their DNA profiles were then analyzed by PFGE and rep-PCR. Salmonella was isolated from 16 out of 600 analyzed samples, with Schwarzengrund serotype presenting the highest incidence, followed by Mbandaka in chicken meat and fecal samples, and Panama in human fecal samples. Some strains isolated from chicken fecal and product samples were indistinguishable by the molecular methods used in the study, suggesting that that the contamination of the broilers on the farm can be transmitted the processed products.(AU)

Seasonal variability of the essential oil of Hesperozygis ringens (Benth.) Epling.

This study was developed to evaluate the effect of seasonality on the yield and chemical composition of the essential oil (EO) of Hesperozygis ringens (Benth.) Epling, a native species from the Brazilian Pampa. Leaves were collected from four specimens of a single population in each of the four seasons for a year and were extracted in triplicate by hydro-distillation for 2 hours. The yield of EO (% w/w) was calculated on fresh weight basis (FWB), and the 16 oil samples were analyzed by gas chromatography coupled to mass spectrometry (GC-MS) and gas chromatography with flame ionization detector (GC-FID). Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA) were used as statistical tools to evaluate differences in chemical composition. The highest yields were obtained in autumn, spring and summer (2.32-4.38%), while the lowest yields were detected in winter, ranging from 1.15 to 1.91%. Oxygenated monoterpenoids were the predominant class of chemical constituents in the EO obtained in all seasons, showing the highest contents in autumn and summer, and pulegone was identified as a major compound, whose contents varied between 54.13 and 81.17%. The EO samples were divided into three chemical groups by HCA and PCA and were assigned to the same group, except for the three samples gathered in winter. The results showed a seasonal influence on the yield and chemical composition of the EO.

Effect of (+)-dehydrofukinone on GABAA receptors and stress response in fish model.

(+)-Dehydrofukinone (DHF) is a major component of the essential oil of Nectandra grandiflora (Lauraceae), and exerts a depressant effect on the central nervous system of fish. However, the neuronal mechanism underlying DHF action remains unknown. This study aimed to investigate the action of DHF on GABAA receptors using a silver catfish (Rhamdia quelen) model. Additionally, we investigated the effect of DHF exposure on stress-induced cortisol modulation. Chemical identification was performed using gas chromatography-mass spectrometry and purity was evaluated using gas chromatography with a flame ionization detector. To an aquarium, we applied between 2.5 and 50 mg/L DHF diluted in ethanol, in combination with 42.7 mg/L diazepam. DHF within the range of 10-20 mg/L acted collaboratively in combination with diazepam, but the sedative action of DHF was reversed by 3 mg/L flumazenil. Additionally, fish exposed for 24 h to 2.5-20 mg/L DHF showed no side effects and there was sustained sedation during the first 12 h of drug exposure with 10-20 mg/L DHF. DHF pretreatment did not increase plasma cortisol levels in fish subjected to a stress protocol. Moreover, the stress-induced cortisol peak was absent following pretreatment with 20 mg/L DHF. DHF proved to be a relatively safe sedative or anesthetic, which interacts with GABAergic and cortisol pathways in fish.

Effect of oil overlay on inhibition potential of roscovitine in sheep cumulus-oocyte complexes.

Inhibitors of cyclin-dependent kinases, as roscovitine, have been used to prevent the spontaneous resumption of meiosis in vitro and to improve the oocyte developmental competence. In this study, the interference of oil overlay on the reversible arrest capacity of roscovitine in sheep oocytes as well as its effects on cumulus expansion was evaluated. For this, cumulus-oocyte complexes (COCs) were cultured for 20 h in TCM 199 with 10% foetal bovine serum (Control) containing 75 µm roscovitine (Rosco). Subsequently, they were in vitro matured (IVM) for further 18 h in inhibitor-free medium with LH and FSH. The culture was performed in Petri dishes under mineral oil (+) or in 96 well plates without oil overlay (-) at 38.5°C and 5% CO2 . At 20 and 38 h, the cumulus expansion and nuclear maturation were evaluated under stereomicroscope and by Hoechst 33342 staining, respectively. No group presented cumulus expansion at 20 h. After additional culture with gonadotrophins, a significant rate of COCs from both Control groups (+/-) exhibited total expansion while in both Rosco groups (+/-) the partial expansion prevailed. Among the oocytes treated with roscovitine, 65.2% were kept at GV in the absence of oil overlay while 40.6% of them reached MII under oil cover (p < 0.05). This meiotic arrest was reversible, and proper meiosis progression also occurred in the Control groups (+/-). So, the culture system without oil overlay improved the meiotic inhibition promoted by roscovitine without affecting the cumulus expansion rate or the subsequent meiosis progression.

Conceptualizing and measuring potentially inappropriate drug therapy.

WHAT IS KNOWN AND OBJECTIVE: Elderly people are the principal consumers of prescription drugs. The more the medication used by the patient, the greater the likelihood there is of the patient being subjected to potentially inappropriate drug therapy (PIDT). PIDT has been measured in the literature with both implicit and explicit tools. The purpose of this review was to assess the use of tools to detect PIDT in various studies and to determine which terms are used to refer to PIDT in practice. METHODS: A systematic review was conducted according to the following steps: the first was identification. In this step, studies were selected from different combinations of the descriptors 'aged', 'elderly', 'inappropriate prescribing' and 'drug utilization' in three different languages, using the Embase, Medline, Scielo, Scopus and Web of Science databases. Second, the papers that satisfied the inclusion criteria for data extraction were carefully examined by three evaluators to determine the tools used and terms that referred to PIDT. RESULTS AND DISCUSSION: From the combinations of keywords, 8610 articles were found. At the end of the selection process, 119 of the articles complied with the specified criteria. The degree of agreement among evaluators was moderate for the study titles (κ1  = 0·479) and substantial for abstracts (κ2  = 0·647). With respect to the PIDT evaluation criteria used by the studies, 27·7% used two criteria. Of the 27 evaluation criteria identified, the Beers criteria were used by 82·3% of the studies. More than 50 different terms to identify PIDT were found in the literature. WHAT IS NEW AND CONCLUSION: This review is the first study to conceptualize and discuss terms that refer to PIDT. At present, there is no consensus regarding terms used to refer to PIDT, with over 50 different terms currently in use. This review shows an increase in the number of articles aimed at evaluating PIDT using implicit and explicit tools.

Larvicidal activity of Brazilian plant essential oils against Coenagrionidae larvae.

Odonate larvae can be serious pests that attack fish larvae, postlarvae, and fingerlings in fish culture tanks, causing significant loss in the supply and production of juveniles. This study reports a screen of the essential oils (EOs) of Nectandra megapotamica (Sprengel) Mez, Nectandra grandiflora Nees, Hesperozygis ringens (Bentham) Epling, Ocimum gratissimum L., Aloysia gratissima (Gillies & Hooker) Troncoso, and Lippia sidoides Chamisso against Coenagrionidae larvae. In addition, the most effective EO and its 50% lethal concentration (LC50) and chemical analysis are described. The larvae of Acanthagrion Selys, Homeoura Kennedy, Ischnura Charpentier, and Oxyagrion Selys were used to assess the EO effects. EO obtained from H. ringens, O. gratissimum, and L. sidoides showed the highest larvicidal effects at 19 h of treatment. The major constituents of the EO of H. ringens include pulegone and limonene, while eugenol and Z-beta-ocimene predominate in the EO of O. gratissimum, and carvacrol and rho-cymene were the major compounds of the EO of L. sidoides. Leaf EOs from H. ringens, O. gratissimum, and L. sidoides showed activity against Coenagrionidae larvae at similar concentrations with LC50s of 62.92, 75.05, and 51.65 microl liter(-1), respectively, and these were considered the most promising treatments.

Ocorrência de Campylobacter em carne de frango, fezes de frango e humanas e pesquisa dos genes cdt / Occurrence of Campylobacter in poultry, meat chicken and human feces, and cdt GENES research

Foram coletadas 100 amostras de conteúdo fecal de aves de corte, 100 de produtos de frango (coxa, sobrecoxa, asa, dorso, carne moída e fígado) e 100 de fezes de humanos, e analisadas para pesquisa de Campylobacter. Realizou-se a determinação da espécie e da presença dos genes cdt, responsáveis pela codificação da toxina citoletal distensiva (CDT), através da técnica da PCR. A bactéria foi isolada de 61% das amostras de fezes de frango, 20% de produtos de frango e 3% de fezes de humanos. A maioria dos isolados foi determinada como C. jejuni . Destes, 93,5% apresentaram os genes para a toxina CDT. Apesar de a ocorrência de Campylobacter em fezes de humanos ter sido baixa, a prevalência em frangos de corte e produtos de frango foi elevada, fato que, aliado à presença dos genes cdt na maioria dos isolados, representa risco potencial para os consumidores. Esses resultados são indicativos da necessidade de medidas preventivas no sistema de produção e de boas práticas de fabricação na indústria, de forma a minimizar a contaminação dos produtos e diminuir o risco para os consumidores.

A hundred chicken fecal samples, a hundred samples of retail poultry products and a hundred samples of human feces were collected and tested for the presence of Campylobacter. The species identification and the analysis for the presence of cdt genes, responsible for encoding the cytolethal distending toxin, were performed by PCR. Campylobacter was found in 61% of the chicken fecal samples, in 20% of the poultry products and in 3% of the human feces. Most isolates were identified as C. jejuni. In 93.5% of these isolates, the cdt genes have been detected. Despite the occurrence of Campylobacter in feces of humans has been low, the prevalence in broilers and poultry products was high, which, combined with the presence of cdt genes in most isolates, represents a potential risk to consumers. These results suggest there is a need for preventive measures in the production system and good manufacturing practices in the industry so as to minimize contamination of products and reduce the risk to consumers.

Avaliação da participação e confiabilidade da população em relação à campanha de vacinação anual contra a raiva de cães e gatos no município de botucatu, são paulo, brasil / evaluation of participation and population reliability regarding annual rabies..

A campanha de vacinação anual contra a Raiva é o procedimento mais eficaz para prevenção desta enfermidade nos cães e gatos e, consequentemente, proteção aos seres humanos. Entretanto, nos anos de 2010 e 2011, esta atividade foi interrompida, no Brasil, pelos eventos adversos associados à vacina ocorridos nesses animais. Mesmo sendo observada uma redução de casos de Raiva canina nas últimas duas décadas, as ações de vigilância devem ser reforçadas, afim de evitar a perda de credibilidade dos donos de animais nas vacinas utilizadas em serviços públicos. O presente trabalho teve como objetivo verificar a participação da população em relação à campanha de vacinação anual em Botucatu. Durante março e abril de 2012, período anterior à 42a campanha, foram entrevistadas 312 pessoas que possuíam cão e/ou gato, em suas residências escolhidas a partir do sorteio de quadras em diferentes setores do Município, sendo todas as casas da quadra eleitas para o processo de amostragem e distribuídas pelos 120

NEUTRÓFILOS E EOSINÓFILOS RELACIONADOS COM A PRESENÇA DE AMASTIGOTAS DE LEISHMANIA INFANTUM NO INTESTINO DE CÃES / NEUTROPHILS AND EOSINOPHILS RELATED TO THE PRESENCE OF Leishmania infantum AMASTIGOTES IN THE GUT OF DOGS

O objetivo foi estudar a presença de neutrófilos e eosinófilos na região intestinal de cães naturalmente infectados com Leishmania infantum em presença e ausência do parasita. Foram analisados 11 cães positivos para Leishmaniose Visceral Canina (LVC) diagnosticados e eutanasiados pelo Centro de Controle de Zoonoses (CCZ) da cidade de Ilha Solteira, SP. Dois grupos foram estabelecidos: cães infectados com LVC com presença de amastigotas de Leishmania no intestino (P, n=5) e cães infectados com LVC, mas sem a presença do parasita no intestino (N, n=6). Secções histológicas do intestino delgado (duodeno, jejuno e íleo) e intestino grosso (cólon) foram submetidos ao processo de coloração por H&E e imunoistoquímica para identificação das células e do parasita, respectivamente. A quantificação celular foi realizada em 10 unidades de vilo/cripta (UVCs) do duodeno, jejuno, íleo e cólon, de cada animal.  Verificou-se que nos tecidos dos cães mais infectados com amastigotas (grupo P) havia menor número de neutrófilos e eosinófilos do que
