Phage types of Salmonella Enteritidis isolated from clinical and food samples, and from broiler carcasses in Southern Brazil

272 isolates of Salmonella Enteritidis (111 isolated from frozen broiler chicken carcasses, 126 from human food and other biological materials involved in food poisoning outbreaks and 35 from different poultry materials) were selected for phage typing. From these, 111 were phage typed, 57.65% being classified as phage type 4, 32.43% as phage type 4a, 3.60% as phage type 6a and 0.90% as phage type 7, whereas 5.40% samples were not phage typeable. The predominance of phage type 4 is in agreement with the results published worldwide, and reinforces the need for studies related to the epidemiological meaning of these findings.

CLINICAL AND EPIDEMIOLOGICAL PROFILE OF ELDERLY PATIENTS WITH CHAGAS DISEASE FOLLOWED BETWEEN 2005-2013 BY PHARMACEUTICAL CARE SERVICE IN CEARÁ STATE, NORTHEASTERN BRAZIL

By controlling the transmission of Chagas disease, the challenge of providing assistance to millions of infected patients that reach old age arises. In this study, the socioeconomic, demographic and comorbidity records of all elderly chagasic patients followed at the Pharmaceutical Care Service of the Chagas Disease Research Laboratory were assessed. The information related to the clinical form of the disease was obtained from medical records provided by the Walter Cantídio University Hospital. The profile of the studied population was: women (50.5%); mean age of 67 years; retired (54.6%); married (51.6 %); high illiteracy rate (40.2%); and family income equal to the minimum wage (51.5%). The predominant clinical forms of Chagas disease were cardiac (65.3%) and indeterminate (14.7%). The main electrocardiographic changes were the right bundle branch block (41.0%), associated or not with the anterosuperior left bundle branch block (27.4%). The average number of comorbidities per patient was 2.23 ± 1.54, with systemic arterial hypertension being the main one found (67.0%). It was found that the elderly comprise a vulnerable group of patients that associate aging with cardiac and/or digestive disorders resulting from the evolution of Chagas disease and other comorbidities, which requires special attention from health services to ensure more appropriate medical and social care.

SEROVARS AND ANTIMICROBIAL RESISTANCE OF Salmonella spp. ISOLATED FROM TURKEY AND BROILER CARCASSES IN SOUTHERN BRAZIL BETWEEN 2004 AND 2006

Salmonella spp. causes diseases in fowls, when species-specific serovars (Salmonella Pullorum and S.Gallinarum) are present in flocks, and public health problems, when non-typhoid serovars are isolated, as well as possible bacterial resistance induced by the preventive and therapeutic use of antimicrobials in animal production. This study describes the serovars and bacterial resistance of 280Salmonella spp. strains isolated from turkey and broiler carcasses in Southern Brazil between 2004 and 2006. SalmonellaEnteritidis was the most prevalent serovar (55.7%), followed by Heidelberg (5.0%), Agona (4.3%), Bredeney (3.9%), Hadar (3.2%), and Typhimurium (2.9%). Tennessee and S. Enterica subspecies enterica(O: 4.5) were isolated only in turkeys, and Hadar (18.6%) was the most prevalent serovar in this species. Antimicrobial susceptibility tests were performed in 178 isolates (43 from turkeys and 135 from broilers). All isolates were sensitive to amoxicillin + clavulanic acid, polymyxin B, ciprofloxacin, and norfloxacin, and were resistant to bacitracin and penicillin. Broiler carcass isolates showed resistance to nalidixic acid (48.9%), nitrofurantoin (34.3%), neomycin (9.6%), tetracycline (5.2%), and kanamycin (8.9%); and turkey carcass isolates were resistant to nalidixic acid (62.8%), tetracycline (34.9%), and neomycin (30.2%), with a significant difference in turkeys when compared to broiler carcass isolates. These results indicate the need for judicious use of antimicrobials in livestock production, given that the serovars identified are potential causes of food poisoning.

Protest attitudes and stated preferences: Evidence on scale usage heterogeneity

We contribute to the stated preference literature by addressing scale usage heterogeneity regarding how individuals answer attitudinal questions capturing lack of trust in institutions and fairness issues. Using a latent class model, we conduct a contingent valuation study to elicit the willingness-to-pay to preserve a recreational site. We find evidence that respondents within the same class, that is, with similar preferences and attitudes, interpret the Likert scale differently when answering the attitudinal questions. We identify different patterns of scale usage heterogeneity within and across classes and associate them with individual characteristics. Our approach contributes to better a understanding of individual behavior in the presence of protest attitudes.

Life (dis)satisfaction and the decision to migrate: Evidence from Central and Eastern Europe

This paper provides empirical evidence of the impact of life satisfaction on the individual intention to migrate. The impacts of individual characteristics and of country macroeconomic variables on the intention to migrate are analyzed jointly. Differently from other studies, we allow for life satisfaction to serve as a mediator between macroeconomic variables and the intention to migrate. Using the Eurobarometer Survey for 27 Central Eastern European (CEE) and Western European (non-CEE) countries, we find that people have a higher intention to migrate when dissatisfied with life. The socio-economic variables and macroeconomic conditions have an effect on the intention to migrate indirectly through life satisfaction. The impact of life satisfaction on the intention to migrate for middle-aged individuals with past experience of migration, low level of education, and with a low or average income from urban areas is higher in CEE countries than in non-CEE countries.

Protesting or justifying? A latent class model for contingent valuation with attitudinal data

This article develops a latent class model for estimating willingness-to-pay for public goods using simultaneously contingent valuation (CV) and attitudinal data capturing protest attitudes related to the lack of trust in public institutions providing those goods. A measure of the social cost associated with protest responses and the consequent loss in potential contributions for providing the public good is proposed. The presence of potential justification biases is further considered, that is, the possibility that for psychological reasons the response to the CV question affects the answers to the attitudinal questions. The results from our empirical application suggest that psychological factors should not be ignored in CV estimation for policy purposes, allowing for a correct identification of protest responses.

Evaluation of the phagocytic activity of peripheral blood monocytes of patients with Jorge Lobo's disease

Studies on host-parasite interaction in Jorge Lobo's disease are scarce, with no report in the literature on the phagocytosis of Lacazia loboi by phagocytic mononuclear cells. Thus, the objective of the present study was to assess the phagocytic activity of blood monocytes in the presence of L. loboi in patients with the disease and in healthy subjects (controls) over 3 and 24 hours of incubation. Statistical analyses of the results showed no significant difference in percent phagocytosis of the fungus between patient and control monocytes. With respect to incubation time, however, there was a significant difference, in that percent phagocytosis was higher at 3 hours than at 24 hours (p <0.01). These results suggest that monocytes from patients with the mycosis are able to phagocyte the fungus, as also observed in control individuals.

Estudo de associação entre antígenos leucocitários humanos e doença de Jorge Lobo

A doença de Jorge Lobo é uma micose cutânea/subcutânea de evolução crônica, causada pelo fungo Lacazia loboi. Devido às características epidemiológicas e poucos estudos relacionados aos aspectos imunológicos dessa doença, o objetivo do trabalho foi investigar uma possível associação das especificidades HLA de classe II em 21 pacientes portadores da doença de Jorge Lobo, comparando com indivíduos sadios de mesma etnia. As tipificações HLA foram realizadas pelo método de PCR-SSP. O resultado não revelou qualquer tipo de associação entre os antígenos HLA e doença de Jorge Lobo. Embora sem significância estatística, foi observada a diminuição da freqüência do antígeno HLA-DR7 no grupo dos pacientes em relação aos controles (0% x 18%), sugerindo uma associação negativa (protetora) entre HLA-DR7 e doença de Jorge Lobo. Contudo, estudos devem ser continuados, objetivando melhor entendimento nos mecanismos envolvidos na suscetibilidade e/ou proteção dessa doença.

Perfil clínico de pacientes chagásicos e não-chagásicos portadores de marca-passo cardíaco artificial

O objetivo do estudo foi comparar pacientes chagásicos e não-chagásicos com marca-passo cardíaco artificial uni ou bicameral quanto à fração de ejeção do ventrículo esquerdo, o limiar de estimulação ventricular e a incidência de arritmias cardíacas. Entre janeiro/2001 e novembro/2002 foram avaliados 45 pacientes chagásicos e 35 não-chagásicos portadores de marca-passo quanto à história clínica, radiografia do tórax, ecocardiograma, Holter 24h e análise telemétrica do marca-passo. Embora os chagásicos fossem mais jovens, os dois grupos foram semelhantes quanto a variáveis radiológicas e o limiar de estimulação ventricular direito. Os chagásicos apresentaram menor fração de ejeção do ventrículo esquerdo ao ecocardiograma e maior incidência de arritmia ventricular ao Holter 24h. Observou-se correlação positiva entre a baixa fração de ejeção do ventrículo esquerdo e a intensidade da arritmia ventricular ao Holter 24h. Em pacientes com marca-passo, a doença de Chagas está associada a marcadores cardíacos de prognóstico adverso.

Active surveillance of American tegumentary leishmaniasis in endemic areas in rural Bolivia

INTRODUCTION: American tegumentary leishmaniasis (ATL), including mucocutaneous leishmaniasis (MCL) and localized cutaneous leishmaniasis (LCL), is endemic in Bolivia. We describe the results of active surveillance of ATL from 2001 to 2006 and assess demographic data related to ATL epidemiology in the Yungas valleys. METHODS: Community-based active ATL surveillance was performed by the institutions SERVIR, CÁRITAS, and the Health Services Department of La Paz, whose files were reviewed retrospectively. A cross-sectional survey was carried out to assess demographic data in two communities. RESULTS: Two thousand nine hundred nine cases of ATL were detected from 2001 to 2006: 2,488 (85.5%) corresponded to LCL and 421 (14.5%) to MCL. A reduction in the proportion of mucosal cases was observed between 2001 and 2006. The proportion of MCL cases increased with age and was higher among males (15.5% versus 12.1%, p=0.018). The rate of positivity via direct observation of the parasite in dermal scrapings and in parasite cultivation was significantly higher for LCL than for MCL (p<0.001 and p=0.009, respectively). The rate of reactivity in the leishmanin skin test was higher in the group with mucosal lesions (p=0.012). The cross-sectional survey showed that 40% of the families had emigrated from the Altiplano. CONCLUSIONS: It is necessary to undertake continuous case detection of ATL in the area, where the disease presents a high rate of mucosal cases. Increasing incidence seems to be associated with immigration and continuous deforestation to expand the crop-growing areas.

Quantificação de fibra alimentar em algumas populações de cubiu (Solanum sessiliflorum dunal), camu-camu (Myrciaria dubia (H.B.K) Mc Vaugh) e açaí (Euterpe oleracea mart)

Considerando a relevância da fibra alimentar na proteção, manutenção e recuperação da saúde e a escassez de tabelas de composição química dos alimentos no que se refere a frutos amazônicos, determinou-se o teor de fibra alimentar em algumas populações de cubiu (Solanum sessiliflonun Dunal), camu-camu (Myrciaria dubia (H.B.K) Mc Vaugh) e açaí (Euterpe oleracea Mart) pelo método enzímico-gravimétrico. Os frutos tiveram diversas procedências: cubiu, da Estação Experimental do INPA/CPCA, camu-camu do município de Barcelos e ao longo da bacia do Rio Amazonas e açaí da bacia do Rio Solimões. Verificou-se que a concentração de fibra alimentar total e insolúvel nas amostras de açaí provenientes de Benjamin Constant (7,66±0,33 g e 6,60±0.IX g) e Anamã (7,45±0,25 g e 6,51±0,04 g), foi significativamente maior (p<0,05), quando comparada com os de outras procedências. Com relação ao cubiu, as maiores concentrações de fibra alimentar total foram detectadas nas amostras Alejo (4,38±0,0 g) e ACSI (3,88±0,18 g), salientando-se que fração analisada inclui a casca, cuja contribuição foi significativamente maior (p<0,05) nas frações insolúvel, solúvel e total. Da mesma forma, os teores de fibra alimentar total (6,18±0,25 g) e insolúvel (5,08±0,14 g) da casca do camu-camu, foram superiores aos encontrados nas demais amostras. Portanto, os frutos analisados apresentaram um potencial relevante como fonte de fibra alimentar, sendo mais uma opção para contribuir na adequação nutricional da população Amazônica e do país.
