Hepatitis C virus prevalence among an immigrant community to the Southern Amazon, Brazil

A community-based random survey was conducted in a southern Brazilian Amazonian county aiming to investigate hepatitis C virus (HCV) infection prevalence and the association of demographic variables and lifestyle behaviours. Seven hundred eighty individuals were serologically screened with a third generation enzyme-linked immunosorbent assay to detect anti-HCV antibodies between 1994/1995. Positive samples were retested for confirmation with a line immunoassay (LIA, Inno-LIA HCV Ab III). Most of these subjects were low income and came from southern Brazilian states (65.8). Two point four percent (IC 95% 1.2%- 4.6%) of the subjects had LIA-confirmed anti-HCV antibodies reactivity. The age-specific prevalence of HCV antibodies slightly increased with age, with the highest prevalence after the age of 40 years. The results of multivariate analysis indicate a strong association between HCV antibodies and previous surgery and history of intravenous drug use. There were no apparent association with gender, hepatitis B virus markers, blood transfusion, and sexual activity. Mean time living in Amazon did not differ between confirmed and negative anti-HCV individuals. The present data point out an intermediate endemicity of HCV infection among this immigrant community to the Amazon region and that few HCV infected participants presented known risk factors.

Health care to immigrant and Portuguese pregnant women in Portugal

This study aimed to assess the care received and the barriers faced by immigrants and Portuguese pregnant women in Portugal. This is an exploratory qualitative study, resorting to applying semi-structured interviews to 60 immigrant and 22 Portuguese women. Content analysis supported by QSR Nvivo10 program was used. The study was approved by an Ethics Committee. The results showed four categories related to affective dimensions-relational, cognitive, technical-instrumental and health care policy for pregnant women. As for the barriers in health care, these were mentioned by some of the expectant mothers, especially immigrant women. Almost all, both immigrant and Portuguese, pregnant women were satisfied with the health care.

Risk perception about zoonoses in immigrants and Italian workers in Northwestern Italy

OBJETIVO: To assess factors associated with a low risk perception of zoonoses and to identify the gaps in knowledge about transmission and prevention of zoonoses in immigrant and Italian workers. MÉTODOS: A cross-sectional study with 175 workers in the agro-livestock and agro-food industry in Piemonte, Italy, was carried out. Data were collected with a semi-structured questionnaire based on knowledge, attitudes and practices (KAP) survey. We calculated proportions and used chi-square tests and odds ratios to assess associations. Eight individual interviews with key informants on immigration and public health in Piemonte were carried out. RESULTADOS: Participants were 82 (47%) Italians and 93 (53%) immigrants. Immigrants were from Romania, Morocco, Albania, India, China, Argentina, Peru, Macedonia, Ivory Coast, Ukraine and Colombia. The study revealed significant differences in risk perception at work (p = 0.001). We found associations between "not having correct knowledge about zoonoses" and the following variables: i. "being immigrant" OR = 4.1 (95%CI 1.7;9.8 p ≤ 0.01); ii. "working in the livestock industry" OR = 2.9 (95%CI 1.2;15.4 p = 0.01); and iii. "being an unqualified worker" OR = 4.4 (95%CI 2.9;15.4 p ≤ 0.01). Another strong association was found between being immigrant and having a low job qualification OR = 6.7 (IC95% 2.9 - 15.4 p ≤ 0.01). Asian immigrants were the group with the highest frequency of risky behaviours and the lowest level of knowledge about zoonoses. CONCLUSÕES: Our results indicate that there were differences in risk perception of zoonoses between the groups participating in our study. These results suggest that immigrant status can be considered a risk factor for having lower risk perception and lower level of knowledge of zoonoses at work. There is a relationship between this specific knowledge of zoonoses and lack of training and instruction among migrant populations. Our results stress the need for developing education programs on zoonoses prevention among the immigrant population in Piemonte, Italy.

African histoplasmosis: report of the first case in Brazil and treatment with itraconazole

We report the first case of African histoplasmosis diagnosed in Brazil. The patient was an immigrant from Angola who had come to Brazil six months after the appearance of the skin lesion. The skin of the right retroauricular area was the only site of involvement. The diagnosis was established by direct mycologic examination, culture and by histopathologic examination of the lesion. The patient was successfully treated with Itraconazole 100mg a day for 52 days. No recurrent skin lesions were observed during the ten month follow-up period.

Effects of immigration on the prevalence of malaria in rural areas of the Amazon basin of Brazil

Epidemiological studies were conducted on malaria in three rural areas of the Amazon basin in the State of Rondônia: the town of Costa Marques, Forte Príncipe da Beira (Fort), and an immigrant settlement in the nearby forest. These studies were instituted to document the malaria problem and to describe the role of immigration on its distribution and prevalence. Hospital records in the town show that the number of malaria cases increased five fold from 1983 to 1987 and that the predominant malaria parasite changel from Plasmodium vivax to P. falciparum. Increased malaria followed increased immigration and colonization of the forest. A series of epidemiologic studies suggested the linkage between malaria and immigration as the prevalence of malaria was 1-2% at the Fort, a stable community, 8-9% at Costa Marques, a growing community, and 14-26% in the new settlements in the forest.

Entrepreneurial decision-making using the knightian uncertainty approach

The article discusses the behavioral aspects that affect the entrepreneurs' decision making under the Knightian uncertainty approach. Since the profit arising from entrepreneurial activity represents the reward of an immeasurable and subjective risk, it has been hypothesized that innovative entrepreneurs have excessive optimism and confidence, which leads them to invest in high-risk activities. A behavioral model of decision making under uncertainty is used to test the hypothesis of overconfidence. This model is based on Bayesian inference, which allows us to model the assumption that these entrepreneurs are overconfident. We conclude that, under the hypothesis of overconfidence, these entrepreneurs decide to invest, despite the fact that the expected utility model indicates the contrary. This theoretical finding could explain why there are a large number of business failures in the first years of activity.

Pregnancy and childbirth: What changes in the lifestyle of women who become mothers?

Pregnancy is a period influenced by the interaction of several factors, therefore this study aimed to identify changes in lifestyles due to pregnancy and childbirth in Portuguese and immigrant women in Portugal. This is a qualitative study, using the semi-structured interview, with eighty-two Portuguese and immigrant women. Content analysis was used, with verbatim classification supported by Nvivo 10. It was authorized by an Ethics Commission. Results revealed that the primary changes in lifestyles due to pregnancy were in eating habits (nutrition), daily activity, exposure to danger, sleep and rest patterns, social and family relationships, going out, self-care, work, clothing and footwear, travel, health monitoring and sexual activity and substances consumption. The main change after the birth, manifested by these women, was that their lives began to revolve around their baby.

Weber e Schumpeter: a ação econômica do empreendedor

Weber and Schumpeter: the Economic action of the entrepreneur. Is there any specificity to be raised in the relations established between entrepreneurs and institutions? Recently, the term entrepreneurship is being widely employed. Enterprising is not anymore a restricted activity to the private sector, but also the Third Sector and the Public Administration. It does not only circumscribe the space of innovation, but also of the adapting changes. In this sense, such elastic concept runs the risk to lose consistency. It seems to be appropriate, therefore, to rescue the meaning that many authors, considered classic in Social Sciences, had attributed to the subject, to show that, although deep socioeconomic transformations occurred since Schumpeter wrote the Theory of the Economic Development, is still necessary to emphasize a basic dimension of the enterprising action: resistance and institutional conflict.
