Strongyloides stercoralis and other Enteroparasites in Children at Uberlândia City, State of Minas Gerais, Brazil

To evaluate the rate of infection by Strongyloides stercoralis and other enteroparasites a survey was conducted in the city of Uberlândia, State of Minas Gerais, Brazil. A total of 900 stool samples from 300 children aging from four months to seven years, randomly selected in ten nursery schools from September 1994 to December 1995, were examined, both by the Baermann-Moraes and Lutz methods. Thirty nine children (13%) were found to be infected by S. stercoralis, 64.1% were boys and 35.9% were girls. Taking all the enteroparasites as a whole the results of the survey pointed out that 265 (88.4%) of the 300 children were infected by the following: Giardia lamblia, 78.3%; Ascaris lumbricoides, 15.3%; S. stercoralis, 13%; Hymenolepis nana, 6.7%; hookworms, 6%; Enterobius vermicularis, 4%; Hymenole-pis diminuta, 4% and Trichuris trichiura, 0.7%. From 265 infected children 64.5% were mono-infected, 27.2% were infected by two parasites and 8.3% had a poly-specific parasite burden. It was concluded that strongyloidiasis is hyperendemic in this area

The Rapakivi texture of feldspars in a plutonic mixing environment - A dissolution-recrystallization process

A new hypothesis is formulated to explain the development of rapakivi texture in and around the mafic enclaves of porphyritic granitoids, i.e. in environments involving magma mixing and mingling. The formation of a plagioclase mantle around alkali feldspar megacrysts is attributed to the localized presence of a melt resulting from the reaction of these megacrysts, with host hybrid magma with which they are in disequilibrium. This feldspathic melt adheres to the resorbed crystals and is virtually immiscible with the surrounding magma. Its composition is modified in terms of the relative proportions of K2O, Na2O, and CaO through selective diffusion of these elements, thus allowing the specific crystallization of andesine. With decreasing temperature, the K-feldspar, again stable, crystallizes along with the plagioclase, leading to mixed mantle structures.

Antigenic and Genetic Characterization of Twenty-six Strains of Human Respiratory Syncytial Virus (Subgroup A) Isolated During Three Consecutive Outbreaks in Havana City, Cuba

Twenty-six human respiratory syncytial virus strains (subgroup A) isolated from three outbreaks in Havana City during the period 1994/95, 1995/96 and 1996/97 were analyzed to determine their antigenic and genetic relationships. Analyses were performed by monoclonal antibodies and restriction mapping (N gene) following amplification of the select region of the virus genome by polymerase chain reaction. All isolated strains were classified as subgroup A by monoclonal antibodies and they showed a restriction pattern NP4 that belonged to subgroup A. Thus the results obtained in this work, showed a close relation (100%) between antigenic and genetic characterization of the isolated strains in our laboratory. These methods permit the examination of large numbers of isolates by molecular techniques, simplifying the researchs into the molecular epidemiology of the virus.

Survey of canine heartworm in the city of Recife, Pernambuco, Brazil

Six hundred and eleven random-source dogs (338 male, 273 female) one year of age or older, from six sections of the city of Recife, Pernambuco, were examined antemortem for circulating microfilariae Dirofilaria immitis and Dipetalonema reconditum adult heartworm (D. immitis) antigen, and examined postmortem for adult heartworms. The prevalence of heartworm infection was 2.3% (14/611), as determined by necropsy for adult worms, and 1% (6/611) had circulating microfilariae of D. immitis; thus, 57.1% of the heartworm-infected dogs had occult infections. The results of serological testing indicated that 1.3% (8/611) of the dogs were positive for adult heartworm antigen. A total of 42 (6.9%) of the dogs had microfilariae of D. reconditum; 40 of these had only D. reconditum and two additional dogs had microfilariae of both species, D. immitis and D. reconditum.

The tick-bird relationship of 56 specimens of birds (Passeriformes and Columbiformes) collected in the city of Curitiba, State of Paraná, between 1990 and 1995, among which 102 specimens of Ixodes (Multidentatus) auritulus were found and analyzed. New host records were also produced including the first report of I. auritulus on a Columbiformes bird in Brazil.

Health and the Built Environment, Sources of Information

The Institute of Public Health in Ireland (IPH) has produced a series of reviews which look at the health impacts of identified subject areas. Four reviews have been produced in the areas of employment, transport, the built environment and education. All reviews may be found at http://www.publichealth.ie/ireland/hiaresources. This resource supplements the ‘Health Impacts of Built Environment’ report. It highlights a number of organisations whose work considers issues relevant to the relationship between health and built environment.

Department for Social Development, Belfast City Centre Northside Urban Village, Draft Regeneration Framework. Health Impact Assessment Report

IPH conducted a rapid HIA appraisal in response to the consultation on DSD Draft Regeneration Framework. The Department for Social Development (DSD) has developed a Draft Regeneration Framework for the North West Quarter Part 2 area of Belfast City Centre, to be known as the Northside Urban Village. The Framework, which outlines the vision for the redevelopment of an inner city area of Belfast was released for public consultation in April 2008. In responding to this consultation, the Institute of Public Health in Ireland (IPH) conducted a Health Impact Assessment (HIA) in order to assess how the proposed Framework might impact on the health of those living in or close to the area as well as the wider Belfast population. The key recommendations which resulted from this process have been presented to the Department. This paper presents an overview of the HIA conducted.

Health Impacts of the Built Environment: A review

This review is the third in the series and illustrates how the built environment impacts on health. It also highlights the unequal distribution of these impacts on different sections of the population. We hope it will help inform debate about the links between the built environment and health and be a useful resource for those working to influence public policy for health at local and national level across the island. The review has an extensive reference list. To supplement the health impacts of the built environment review a 'sources of information' list has been developed which highlights a number of organisations whose work considers issues relevant to the relationship between health and the built environment.

Ireland on the move: Enhancing opportunities for physical activity in the built environment

The Institute of Public Health in Ireland recently hosted a seminar on physical activity. The seminar presentations were: Ms Teresa Lavin, IPH - Physical activity and the built environment in Ireland Prof James Sallis, Professor of Psychology at San Diego State University and Director of Active Living Research - Translating evidence from physical activity research into practice.

IPH Submission to Department of the Environment, Heritage and Local Government Climate Change Response Bill 2010

The main purpose of the Clmate Change Bill is to provide for the adoption of a national policy for reducing greenhouse gas (GHG) emissions; to support this through the making of mitigation and adaptation action plans; and to make provision for emission reduction targets to support the objective of transition to a low carbon, climate resilient and environmentally sustainable economy.The remit of the Institute of Public Health in Ireland (IPH) is to promote cooperation for public health between Northern Ireland and the Republic of Ireland in the areas of research and information, capacity building and policy advice. Our approach is to support Departments of Health and their agencies in both jurisdictions, and maximise the benefits of all-island cooperation to achieve practical benefits for people in Northern Ireland and the Republic of Ireland.IPH has a keen interest in the effects of climate change on health. In September 2010 the IPH published a paper – Climate Change and Health: A platform for action - to inform policy-makers and the public about the health benefits in reducing greenhouse gas emissions. This paper followed a seminar with international speakers, opened by Minister Gormley, on the same topic in February 2010. 

IPH response to Department of the Environment, Heritage and Local Government and the Department for Regional Development Spatial Strategies

The remit of the Institute of Public Health in Ireland (IPH) is to promote cooperation for public health between Northern Ireland and the Republic of Ireland in the areas of research and information, capacity building and policy advice. Our approach is to support Departments of Health and their agencies in both jurisdictions, and maximise the benefits of all-island cooperation to achieve practical benefits for people in Northern Ireland and the Republic of Ireland. As an all-island body, the Institute of Public Health in Ireland particularly welcomes that the Framework for Collaboration has been co-produced by the Department for Regional Development and the Department of the Environment, Heritage and Local Government. In addition the Institute of Public Health welcomes a more holistic approach to spatial planning that takes into account the environment and sustainable economic development. A clean environment and a more equitable distribution of prosperity have associated health benefits, as outlined in the IPH’s Active travel – healthy lives (2011) and Health impacts of the built environment- a review (2006).

Consideration of health in Strategic Environment Assessment (SEA) on the island of Ireland

This IPH report explores the extent health was incorporated into SEA in a manner which would suggest a good understanding of the many social and economic factors which strongly influence health. The research identifies that a consideration of health is not routinely included in SEAs. There is a need to build capacity and change mindsets in how SEAs are undertaken to more completely factor in the health impacts.

IPH response to Department of Environment (NI) Planning Policy Statement 7

The Institute of Public Health in Ireland (IPH) aims to improve health on the island of Ireland by working to combat health inequalities and influence public policies in favour of health.  The Institute promotes cooperation between Northern Ireland and the Republic of Ireland in public health research, training and policy advice. IPH acknowledge that health is influenced by a wide range of social determinants, including economic, environmental, social and biological factors.  Housing and residential areas are identified as key determinants of health and IPH welcomes the opportunity to comment on the Department of the Environment (DoE), Draft Addendum to Planning Policy Statement 7.

IPH response to Department of the Environment (NI) Planning Policy Statement 21 (PPS21)

In responding, IPH identify a number of potential health impacts including providing employment opportunities through farm diversification.  Other issues include access to open space and housing located close to traditional focal points.   The Institute of Public Health in Ireland (IPH) is an all-island body which aims to improve health in Ireland, by working to combat health inequalities and influence public policies in favour of health. IPH promotes co-operation in research, training, information and policy in order to contribute to policies which tackle inequalities in health. IPH is particularly interested in the Draft Planning Policy Statement 21 due to the impact on the countryside and potential implications on health for the population of Northern Ireland. IPH conducted a Health Impact Assessment on the proposed West Tyrone Area Plan 2019 and through this work has developed extensive knowledge when looking at health and rural issues.

Submission to the Department of Environment, Heritage and Local Government: Sustainable Residential Development in Urban Areas

The Institute of Public Health in Ireland is an all-island body which aims to improve health in Ireland by working to combat health inequalities and influence public policies in favour of health. The Institute promotes co-operation in research, training, information and policy in order to contribute to policies which tackle inequalities in health.   Over the past ten years the Institute has worked closely with the Department of Health and Children and the Department of Health, Social Services and Public Safety in Northern Ireland to build capacity for public health across the island of Ireland.   The Institute takes the view that health is determined by policies, plans and programmes in many sectors outside the health sector as well as being dependent on access to and availability of first class health services. The importance of other sectors is encapsulated in a social determinants of health perspective which recognises that health is largely shaped and influenced by the physical, social, economic and cultural environments in which people live, work and play. Figure 1 illustrates these multi-dimensional impacts on health and also serves to highlight the clear and inextricable links between health and sustainable development. Factors that impact on long-term sustainability will thus also impact on health.
