Gender differences in Leptospira exposure risk, perceptions of disease severity, and high-risk behaviours in Salvador, Brazil: A cross-sectional study
Vulnerability to climate hazards and infectious diseases is not gender-neutral, meaning that men, women, and other gender identities experience different risks. Leptospirosis is a zoonotic climate-sensitive infectious disease caused by the bacteria Leptospira and is transmitted to humans through contact with infected animals or contaminated environments, particularly soil and floodwater. Globally, studies report a higher risk of leptospiral infec…
Invisibilidade de pessoas com deficiência durante a pandemia da Covid-19: Narrativas na cidade de Vitória/ES
Este artigo objetiva compreender de que modo a invisibilização das pessoas com deficiência impactou as formas como essa população vivenciou a pandemia da Covid-19 na cidade de Vitória/ES. Com base nas narrativas coletadas em 13 entrevistas semiestruturadas com pessoas com deficiência moradoras de Vitória, são analisadas três categorias principais: os sentimentos de medo relacionados aos riscos e incertezas do período pandêmico; a ampliação das ba…
Predictors of Neurodevelopment in Microcephaly Associated with Congenital Zika Syndrome: A Prospective Study
EI predicted neurodevelopmental delay in all Bayley domains in children with microcephaly associated with CZS
Why is leptospirosis hard to avoid for the impoverished? Deconstructing leptospirosis transmission risk and the drivers of knowledge, attitudes, and practices in a disadvantaged community in Salvador,…
Several studies have identified socioeconomic and environmental risk factors for infectious disease, but the relationship between these and knowledge, attitudes, and practices (KAP), and more importantly their web of effects on individual infection risk, have not previously been evaluated. We conducted a cross-sectional KAP survey in an urban disadvantaged community in Salvador, Brazil, leveraging on simultaneously collected fine-scale environmen…
Rat infestation associated with environmental deficiencies in an urban slum community with high risk of leptospirosis transmission
We analyzed environmental factors that provide food, water and harborage to rodents and the risk of household rodent infestation in a slum community with a high risk of leptospirosis transmission. Detailed environmental surveys were performed in 221 households. Multivariate regression models evaluated the association between rodent infestation and socioeconomic status and environmental attributes obtained from Geographical Information System surv…
Hypertension in a Brazilian Urban Slum Population
Low- and middle-income countries account for the majority of hypertension disease burden. However, little is known about the distribution of this illness within subpopulations of these countries, particularly among those who live in urban informal settlements. A cross-sectional hypertension survey was conducted in 2003 among 5649 adult residents of a slum settlement in the city of Salvador, Brazil. Hypertension was defined as either an elevated a…
The impact of Brazil’s Bolsa Família conditional cash transfer program on children’s health care utilization and health outcomes
BACKGROUND: Conditional cash transfer (CCT) programs provide poor families with cash conditional on investments in health and education. Brazil's Bolsa Família program began in 2003 and is currently the largest CCT program in the world. This community-based study examines the impact of Bolsa Família on child health in a slum community in a large urban center. METHODS: In 2010, detailed household surveys were conducted with randomly selected Bolsa…
Surveillance for leptospirosis in the Americas, 1996-2005: A review of data from ministries of health
OBJECTIVE: To characterize current leptospirosis reporting practices in the Americas. METHODS: Information was collected from the official websites of national ministries of health from the Americas region and two international organizations; personal communications; and three international morbidity databases. For all sources other than the morbidity databases, the review was limited to official reports citing clinically suspected and laboratory…
P2-506 Influence of climate on the incidence of urban leptospirosis
Introduction Leptospirosis has emerged as an important health problem in developing countries due to the growth of slum settlements worldwide, where poor sanitation favours rat-borne transmission. Large urban epidemics occur during seasonal periods of heavy rainfall. However, a detailed analysis has not been performed to determine how rainfall, as well as other climatic factors, specifically influences the risk of leptospirosis in these endemic s…
First insights into the genetic diversity of Mycobacterium tuberculosis strains in Salvador, Bahia State, Brazil
This study constitutes a first attempt to describe the genetic population structure of Mycobacterium tuberculosis circulating in Salvador, Bahia State, Brazil. A total of 56 confirmed cases of pulmonary tuberculosis, identified between March and June 2008, were analyzed using restriction fragment length polymorphism (IS6110-RFLP). The study population was characterized by a predominance of males (71.43%) over 30 years of age (68.75%). Forty-one i…

Slum health: Diseases of neglected populations
BACKGROUND: Urban slums, like refugee communities, comprise a social cluster that engenders a distinct set of health problems. With 1 billion people currently estimated to live in such communities, this neglected population has become a major reservoir for a wide spectrum of health conditions that the formal health sector must deal with. DISCUSSION: Unlike what occurs with refugee populations, the formal health sector becomes aware of the health …
Hemoglobinopathies in newborns from Salvador, Bahia, Northeast Brazil
Hemoglobinopathies are hereditary disorders of the hemoglobin molecule with a high prevalence worldwide. Brazil has a prevalence of 0.1 to 0.3% of newborns with sickle cell anemia and 20.0 to 25.0% of heterozygous alpha2 thalassemia among African Brazilians. In the present study, we investigated the presence of variant hemoglobins and alpha2(3.7 Kb) and alpha2(4.2 Kb) thalassemia in newborns from Salvador, Bahia, Brazil. Samples of umbilical cord…
C677T polymorphism of the MTHFR gene and variant hemoglobins: A study in newborns from Salvador, Bahia, Brazil
The C677T polymorphism in the methylenetetrahydrofolate reductase gene (MTHFR) is associated with an increase in total homocysteine serum levels (tHcy), described as a risk factor for cardiovascular disease. Eight hundred forty-three neonates from two different maternity hospitals, one public and another private, in Salvador, Bahia, Brazil were screened for this polymorphism by PCR and RFLP. The T-allele frequency in the total sample was 0.23, an…
Fatores de risco para anemia por deficiência de ferro em crianças e adolescentes parasitados por helmintos intestinais
The initiatives to control anemia in the group at greatest risk, as identified in this study, should seek to increase the consumption of iron-rich foods, boost the bioavailability of the iron ingested, and improve socioenvironmental conditions
Epidemiologia do desenvolvimento cognitivo de escolares em Jequié, Bahia, Brasil: Procedimentos De Avaliação E Resultados Gerais
Este artigo descreve metodologia, aplicação e utilidade do teste das Matrizes Progressivas de Raven e do Teste de Sondagem Intelectual (TSI), comparando-os ainda com o rendimento escolar do aluno, em Jequié, Bahia. O Raven, que avalia o raciocínio não-verbal, foi aplicado a 374 escolares (7 a 17 anos). Somente 231 TSI foram respondidos porque requeriam habilidades de leitura e escrita. Foram coletadas notas escolares para todos os participantes. …
