Immature Aedes mosquitoes colonize Culex quinquefasciatus breeding sites in neighborhoods in the municipality of Olinda, State of Pernambuco

Introduction The present study shows the colonization of Aedes mosquitoes in breeding sites specific for Culex quinquefasciatus in neighborhoods in the municipality of Olinda. Methods Samples were collected between May 2011 and June 2012 from breeding sites positive for Cx. quinquefasciatus by using a ladle and manual suction pump. Results Aedes aegypti (0.12%), Aedes albopictus (0.03%), and Cx. quinquefasciatus (99.8%) were found across the breeding sites. Conclusions The presence of Aedes ssp. in several Cx. quinquefasciatus breeding sites with a heavy load of organic material demonstrates the need to review the concepts and methods used for treatment, as the use of specific larvicide for breeding sites of Culex.

Movilidad social en barrios de Córdoba: Villa La Tela y áreas colindantes. Social Mobility in Neighborhoods of Cordoba: Villa La Tela and Adjacent Areas.

Esta investigación propone aproximarse al conocimiento y comprensión de los diversos mecanismos de movilidad social en Villa La Tela barrios adyacentes (ciudad de Córdoba). Si bien las poblaciones objetivo poseen diferentes niveles de vida, este proyecto no se propone la comparación entre ambos sectores urbanos, sino la identificación de diversos patrones de movilidad social vigentes. Se intenta también aproximarse indirectamente al esquema de estratificación social vigente en la ciudad de Córdoba. El equipo se propone avanzar en la definición de una estrategia metodológica que permita comprender de una manera integral los diversos mecanismos de movilidad social. Se propone articular una triangulación de métodos cuantitativos y cualitativos que aproveche las fortalezas de cada enfoque para efectuar una mirada multidisciplinaria de las condiciones de vida de la población en estudio. Se intenta también aprovechar la inserción que ya tienen algunos de los investigadores del equipo en los barrios, a fin de aportar conocimientos útiles a las organizaciones que realizan actividades de intervención social. El trabajo se propone en tres fases constituidas por tres instancias que no necesariamente se corresponden con tiempos cronológicos: análisis de información secundaria (censos de población, relevamientos de organismos gubernamentales y civiles) y de resultados de investigaciones previas; en otra fase se generará un espacio recreativo en la comunidad que permita identificar las percepciones subjetivas de los actores locales en relación a las condiciones de vida y la experiencia de movilidad social (etnodrama, etnografía fotográfica); finalmente se realizará una fase de trabajo de encuestas y entrevistas en profundidad a partir de los insumos producidos en las dos fases antes mencionadas. Se tomará para ello, como unidad de análisis socio-económica a los hogares, considerados como el espacio físico y social desde el cual se diseñan e implementan las estrategias familiares de vida de sus miembros. Se considera que el proyecto puede transferir los resultados -parciales y finales- alcanzados a las instituciones intervinientes en los barrios considerados. Esta transferencia constituye una actividad de extensión concreta, dado que las intervenciones en marcha están destinadas a mejorar las condiciones de vida de la población en términos materiales y culturales. La acción sinérgica entre las diversas instituciones que intervienen o investigan sobre estas comunidades es un compromiso, ya que de ello depende la calidad del impacto en las propias comunidades. En este sentido, la descripción de las experiencias intergeneracionales de movilidad social de los hogares y su significación subjetiva, puede considerarse de interés tanto para las instituciones como para la comunidad misma. De esta manera se espera devolver a las comunidades lo que éstas le ofrezcan al equipo de investigación, como flujo de intercambio recíproco de conocimiento y desarrollo humano. Desde el punto de vista metodológico, el equipo espera realizar una evaluación de los distintos abordajes cuantitativos y cualitativos a escala microsocial, a fin de realizar propuestas válidas para nuevas investigaciones en ámbitos locales. This research proposes to approach the knowledge and understanding of the various mechanisms of social mobility in adjacent neighborhoods of Villa La Tela (Cordoba, Argentina). Although the target populations have different levels of life, this project does not intend to compare urban areas, but the identification of different patterns of social mobility nowadays. Indirect approach is also intended to outline the existing social stratification in Cordoba city. We plan to define a methodological approach based on triangulation of quantitative and qualitative methods, exploiting the strengths of each approach to make a multidisciplinary vision of the population living conditions. Project proposes phases consisting of three instances, that do not necessarily correspond with chronological time: 1) secondary data analysis (population censuses, surveys of government agencies and civilian organizations) and previous research results; 2) promotion of a recreation space in the community to identify the subjective perceptions of local actors in relation to living conditions and experience of social mobility; 3) finally there will be a phase of survey work and deep interviews from inputs produced in the two phases mentioned above. Households will be taken as socio-economic unit, also considered as social and physical space where family strategies of life are designed and implemented by its members. We considere this project can transfer the obtained results to the institutions involved in the concerned districts. This transfer is a specific outreach activity, since the interventions in place are aimed to improving the living conditions of population in material and cultural terms.

Distribution of dengue vectors in neighborhoods with different urbanization types of Manaus, state of Amazonas, Brazil

Aedes aegypti and Ae. albopictus are vectors of dengue viruses, which cause endemic disease in the city of Manaus, capital of the state of Amazonas, Brazil. More than 53 thousand cases have been registered in this city since the first epidemic in 1998. We evaluated the hypothesis that different ecological conditions result in different patterns of vector infestation in Manaus, by measuring the infestation level in four neighborhoods with different urbanization patterns, during the rainy (April), dry (August), and transitional (November) seasons. Ae. aegypti predominated throughout the study areas and sampling periods, representing 86% of all specimens collected in oviposition traps. High frequencies of houses positive for both species were observed in all studied sites, with Ae. aegypti present in more than 84% of the houses in all seasons. Ae. albopictus, on the other hand, showed more spatial and temporal variation in abundance. We found no association between infestation level and house traits. This study highlights the homogeneity of dengue vector distribution in Manaus.

Social support, socioeconomic and clinical risk: comparison between to neighborhoods in a Brazilian upcountry town

The objective of this study was to compare the perceptions of two families living in two different neighborhoods (rated according to risk levels) regarding social support. A questionnaire was designed to assess social support according to the following dimensions: instrumental, emotional, religious, and support from friends, neighbors and family. The sample was comprised as follows: considering the 114 families living in neighborhood 1, 52 families were interviewed; and among the 162 families living in neighborhood 2, 60 families were interviewed. No significant difference was found related to instrumental, religious and emotional support, including the support from relatives among the families from both neighborhoods. The results disagree with the reviewed literature, which indicated a strong association between social support and families living at socioeconomic risk. In conclusion, social support is important for families, regardless of their risk stratification.

Banks and the Racial Patterning of Homicide: A Study of Chicago Neighborhoods

While bank investment is a driving force behind neighborhood viability, few studies have directly examined the effects of bank loan practices on neighborhood crime rates. This paper proposes that residential bank loan policies help explain the higher rates of homicide in minority neighborhoods in Chicago compared to white neighborhoods. It finds that black and Latino neighborhoods would experience fewer homicides if more financial capital were infused into these neighborhoods. These findings suggest that neighborhoods are shaped profoundly by the decisions of external economic actors.

Prevalence and risk factors for human immunodefiency virus and hepatitis C virus co-infection among drug users in innercity neighborhoods in Houston, Texas

Background. There are 200,000 HIV/HCV co-infected people in the US and IDUs are at highest risk of exposure. Between 52-92% of HIV infected IDUs are chronically infected with HCV. African Americans and Hispanics bear the largest burden of co-infections. Furthermore HIV/HCV co-infection is associated with high morbidity and mortality if not treated. The present study investigates the demographic, sexual and drug related risk factors for HIV/HCV co-infection among predominantly African American injecting and non-injecting drug users living in two innercity neighborhoods in Houston, Texas. ^ Methods. This secondary analysis used data collected between February 2004 and June 2005 from 1,889 drug users. Three case-comparison analyses were conducted to investigate the risk factors for HIV/HCV co-infection. HIV mono-infection, HCV mono-infection and non-infection were compared to HIV/HCV co-infection to build multivariate logistic regression models. Race/ethnicity and age were forced into each model regardless of significance in the univariate analysis. ^ Results. The overall prevalence of HIV/HCV co-infection was 3.9% while 39.8% of HIV infected drug users were co-infected with HCV and 10.7% of HCV infected drug users were co-infected with HIV. Among HIV infected IDUs the prevalence of HCV was 71.7% and among HIV infected NIDUs the prevalence of HCV was 24%. In the multivariate analysis, HIV/HCV co-infection was associated with injecting drug use when compared to HIV mono-infection, with MSM when compared to HCV mono-infection and with injecting drug use as well as MSM when compared to non-infection. ^ Conclusion. HIV/HCV co-infection was associated with a combination of sexual and risky injecting practices. More data on the prevalence and risk factors for co-infection among minority populations is urgently needed to support the development of targeted interventions and treatment options. Additionally there should be a focus on promoting safer sex and injecting practices among drug users as well as the expansion of routine testing for HIV and HCV infections in this high risk population.^

Follow-up care after a health fair screening in three Houston neighborhoods in 2008

Background. Each year thousands of people participate in mass health screenings for diabetes and hypertension, but little is known about whether or not those who receive higher than normal screening results obtain the recommended follow-up medical care, or what barriers they perceive to doing so. ^ Methods. Study participants were recruited from attendees at three health fairs in low-income neighborhoods in Houston, Texas Potential participants had higher than normal blood pressure (> 90/140 mgHg) or blood glucose readings (100 mm/dL fasting or 140 mm/dL random). Study participants were called at one, two, and three months and asked if they had obtained follow-up medical care; those who had not yet obtained follow-up care were asked to identify barriers. Using a modified Aday-Andersen model of health service access, the independent variables were individual and community characteristics and self-perceived need. The dependent variable was obtaining follow-up care, with barriers to care a secondary outcome. ^ Results. Eighty-two study participants completed the initial questionnaire and 59 participants completed the study protocol. Forty-eight participants (59% under an intent to treat analysis, 81% of those completing the study protocol) obtained follow-up care. Those who completed the initial questionnaire and who reported a regular source of care were significantly more likely to obtain follow-up care. For those who completed the study protocol the relationship between having a regular source of care and obtaining follow-up care approached but did not reach significance. For those who completed the initial questionnaire, self-described health status, when examined as a binary variable (good, very good, excellent, or poor, fair, not sure) was associated with obtaining follow-up care for those who rated their health as poor, fair, or not sure. While the group who completed the study protocol did not reach statistical significance, the same relationship between self-described health status of poor, fair, or not sure and obtaining follow-up care was present. The participants who completed the study protocol and described their blood pressure as OK or a little high were statistically more likely to get follow-up care than those who described it as high or very high. All those on oral medications for hypertension (12/12) and diabetes (4/4) who were told to obtain follow-up care did so; however, the small sample size allows this correlation to be of statistical significance only for those treating hypertension. ^ The variables significantly associated with obtaining follow-up care were having a regular source of care, self-described health status of poor, fair, or not sure, self-described blood pressure of OK or a little high, and taking medication for blood pressure. ^ At the follow-up telephone calls, 34 participants identified barriers to care; cost was a significant barrier reported by 16 participants, and 10 reported that they didn’t have time because they were working long hours after Hurricane Ike. ^ The study included the offer of access assistance: information about nearby safety-net providers, a visit to or information from the Health Information Center at their Neighborhood Center location, or information from Project Safety Net (a searchable web site for safety net providers). Access assistance was offered at the health fairs and then again at follow-up telephone calls to those who had not yet obtained follow-up care. Of the 48 participants who reported obtaining follow-up care, 26 said they had made use of the access assistance to do so. The use of access assistance was associated with being Hispanic, not having health insurance or a regular source of care, and speaking Spanish. It was also associated with being worried about blood glucose. ^ Conclusion. Access assistance, as a community enabling characteristic, may be useful in aiding low-income people in obtaining medical care. ^

Has the development of a New Urbanist community affected the physical activity levels of residents in surrounding neighborhoods?

Study Aims. The neighborhood environment has been shown to influence physical activity levels, but little is known about how far-reaching these effects are. This study sought to determine whether or not the development of a New Urbanist community in Austin, Texas affected the physical activity levels of residents in surrounding neighborhoods. The results were stratified by demographic characteristics, residential distance from the New Urbanist community, and type of physical activity to determine if any observed changes varied by these factors.^ Methods. Self-report questionnaires were mailed to a random sample of households located within one mile of the New Urbanist development. The questionnaire included questions about physical activity behaviors before and after the community was constructed in 2006. Changes in reported levels of physical activity between the two time points were examined.^ Results. The prevalence and average minutes per week of total physical activity did not change. Significant increases in the frequency and quantity of moderate-intensity leisure-time physical activity were observed. The amount of time spent walking and biking for recreation outside of the neighborhood increased significantly among those living close to Mueller. The weekly time spent in vigorous-intensity activity increased significantly, especially among those living closer to Mueller. There were significant decreases in the prevalence of and time spent walking for transport. The use of Mueller parks and trails was highest among participants living close to Mueller.^ Conclusions. The nearby Mueller development does not appear to have encouraged sedentary members of the surrounding population to become physically active, but might be associated with increased weekly physical activity among those who were already active. The increase in vigorous-intensity physical activity and recreational walking/biking outside of the neighborhood among those subjects living closer to Mueller may be attributed to the use of Mueller parks and trails, which was also considerably higher among this group. People may be substituting the time they spent walking for transport before the Mueller development with moderate-intensity leisure-time physical activity. Future research should seek to identify barriers that may be preventing more nearby residents from using Mueller facilities for physical activity. ^
