Full Text Available Updated spatial information on the dynamics of slums can be helpful to measure and evaluate progress of policies. Earlier studies have shown that semi-automatic detection of slums using remote sensing can be challenging considering the large variability in definition and appearance. In this study, we explored the potential of an object-oriented image analysis (OOA method to detect slums, using very high resolution (VHR imagery. This method integrated expert knowledge in the form of a local slum ontology. A set of image-based parameters was identified that was used for differentiating slums from non-slum areas in an OOA environment. The method was implemented on three subsets of the city of Ahmedabad, India. Results show that textural features such as entropy and contrast derived from a grey level co-occurrence matrix (GLCM and the size of image segments are stable parameters for classification of built-up areas and the identification of slums. Relation with classified slum objects, in terms of enclosed by slums and relative border with slums was used to refine classification. The analysis on three different subsets showed final accuracies ranging from 47% to 68%. We conclude that our method produces useful results as it allows including location specific adaptation, whereas generically applicable rulesets for slums are still to be developed.

Urbanization and Slum Formation

The formation of slums need not be inevitable with rapid urbanization. Such an argument appears to be contradicted by evidence of large slum populations in a large number of developing countries and particularly in rapidly urbanizing regions like Asia. The evidence discussed suggests that city authorities faced with rapid urban development lack the capacity to cope with the diverse demands for infrastructural provision to meet economic and social needs. Not only are strategic planning and intervention major issues in agenda to manage rapid urbanization, but city governments are not effectively linking the economic development trajectory to implications for urban growth and, hence, housing needs. In the following discussion, a case study is presented in support of the argument that city governments have to first recognize and then act to establish the link that is crucial between economic development, urban growth, and housing. This is the agendum that has been largely neglected by city and national governments that have been narrowly focused on economic growth with the consequent proliferation of slum formation as a housing solution.

Brazil's National Tuberculosis Control Program seeks to improve tuberculosis (TB) treatment in vulnerable populations. Slum residents are more vulnerable to TB due to a variety of factors, including their overcrowded living conditions, substandard infrastructure, and limited access to healthcare compared to their non-slum dwelling counterparts. Directly observed treatment (DOT) has been suggested to improve TB treatment outcomes among vulnerable populations, but the program's differential effectiveness among urban slum and non-slum residents is not known. We retrospectively compared the impact of DOT on TB treatment outcome in residents of slum and non-slum census tracts in Rio de Janeiro reported to the Brazilian Notifiable Disease Database in 2010. Patient residential addresses were geocoded to census tracts from the 2010 Brazilian Census, which were identified as slum (aglomerados subnormais -AGSN) and non-slum (non-AGSN) by the Census Bureau. Homeless and incarcerated cases as well as those geocoded outside the city's limits were excluded from analysis. In 2010, 6,601 TB cases were geocoded within Rio de Janeiro; 1,874 (27.4 %) were residents of AGSN, and 4,794 (72.6 %) did not reside in an AGSN area. DOT coverage among AGSN cases was 35.2 % (n = 638), while the coverage in non-AGSN cases was 26.2 % (n = 1,234). Clinical characteristics, treatment, follow-up, cure, death and abandonment were similar in both AGSN and non-AGSN TB patients. After adjusting for covariates, AGSN TB cases on DOT had 1.67 (95 % CI: 1.17, 2.4) times the risk of cure, 0.61 (95 % CI: 0.41, 0.90) times the risk of abandonment, and 0.1 (95 % CI: 0.01, 0.77) times the risk of death from TB compared to non-AGSN TB cases not on DOT. While DOT coverage was low among TB cases in both AGSN and non-AGSN communities, it had a greater impact on TB cure rate in AGSN than in non-AGSN populations in the city of Rio de Janeiro.

The Urbanization, Poverty, and Health Dynamics research program was designed to generate and provide the evidence base that would help governments, development partners, and other stakeholders understand how the urban slum context affects health outcomes in order to stimulate policy and action for uplifting the wellbeing of slum residents. The program was nested into the Nairobi Urban Health and Demographic Surveillance System, a uniquely rich longitudinal research platform, set up in Korogocho and Viwandani slum settlements in Nairobi city, Kenya. Findings provide rich insights on the context in which slum dwellers live and how poverty and migration status interacts with health issues over the life course. Contrary to popular opinions and beliefs that see slums as homogenous residential entities, the findings paint a picture of a highly dynamic and heterogeneous setting. While slum populations are highly mobile, about half of the population comprises relatively well doing long-term dwellers who have lived in slum settlements for over 10 years. The poor health outcomes that slum residents exhibit at all stages of the life course are rooted in three key characteristics of slum settlements: poor environmental conditions and infrastructure; limited access to services due to lack of income to pay for treatment and preventive services; and reliance on poor quality and mostly informal and unregulated health services that are not well suited to meeting the unique realities and health needs of slum dwellers. Consequently, policies and programs aimed at improving the wellbeing of slum dwellers should address comprehensively the underlying structural, economic, behavioral, and service-oriented barriers to good health and productive lives among slum residents.

Circular migration patterns and determinants in Nairobi slum settlements

Directory of Open Access Journals (Sweden)

Donatien Beguy

2010-09-01

Full Text Available This paper measures migration flows and determinants in two slum settlements in Nairobi City between 2003 and 2007. The results confirm the high intensity of migration with a quarter of the total slum population and a third of those aged 15-30 being renewed annually. A circular migration system is at play whereby the majority of slum dwellers are short-term migrants spending on average less than 3 years in the area. Migration is more intense during early adulthood (20-24, and despite very similar determinants across gender, mobility is more intense among women compared to men. The increasing feminization of migration is likely to change the face of slum settlements, resulting in more balanced sex ratios, in line with city-wide trends in Nairobi over the past half century. The high population turnover is due to the insecurity of livelihoods, tenure, and poor basic amenities and social services in slum settlements.

Migration and labour characteristics of slum dwellers in Bombay.

Science.gov (United States)

Desai, V

1994-03-01

This article presents a description of the migration and labor force characteristics of a sample of Bombay households in three slum areas. Interviews were conducted among 135 households in 1989. Slum areas were both similar and different from one another. Wadala slum had a large migrant population and a more integrated community structure. Slum dwellers tended to retain assets at their place of origin and were from agricultural areas in south Maharashtra. A greater proportion had close kin living in Wadala. Slum dwellers tended to be better-educated, formal-sector workers. Worli slum was less affluent and less close-knit. Migrants were mostly external migrants from Uttar and Andhra Pradesh. Kurla slum was the oldest slum area and had mixed traits. Kin interaction was voluntary and selective and flexible. The decision to return was unrelated to years spent in Bombay. Survey findings indicate that all areas had roughly equal proportions of internal and external migrants. Villagers migrated to cities due to unemployment in villages and the opportunity for social mobility and better employment. This analysis indicates that community-based politics were more influenced by state concerns than by the attributes of settlers or settlement types. State policies and market forces constrained poor people's housing options. The cost of urban housing and amenities rises as population density increases. The demand in urban areas for public services, housing, and infrastructure increases due to expanding populations, inadequate and deteriorating facilities, and social pressures. Governments are constrained by high debt levels and inadequate revenues. National agencies may be inefficient in the provision of services and infrastructure. There is growing pressure on international donors and developing country governments to reexamine the role of the private sector in financing and providing services and infrastructure.

Slum Definitions in Urban India: Implications for the Measurement of Health Inequalities

Science.gov (United States)

Nolan, Laura B.

2015-01-01

Half the population of low- and middle-income countries will live in urban areas by 2030, and poverty and inequality in these contexts is rising. Slum dwelling is one way in which to conceptualize and characterize urban deprivation but there are many definitions of what constitutes a slum. This paper presents four different slum definitions used in India alone, demonstrating that assessments of both the distribution and extent of urban deprivation depends on the way in which it is characterized, as does slum dwelling’s association with common child health indicators. Using data from India’s National Family and Health Survey from 2005–2006, two indictors of slum dwelling embedded in the survey and two constructed from the household questionnaire are compared using descriptive statistics and linear regression models of height- and weight-for-age z-scores. The results highlight a tension between international and local slum definitions, and underscore the importance of improving empirical representations of the dynamism of slum and city residents.

DEFINING SLUMS USING MULTIDIMENSIONAL AND RELATIONAL PROPERTIES: A DYNAMIC FRAMEWORK FOR INTERVENTION

Full Text Available Phenomenon as old as cities themselves, slums - in their many permutations - have been part of city management for a long time. Descriptions and definitions have gone through trends and so have the strategies to address their conditions and relationship to cities. Summarising various trends, definitions and approaches to solutions of slums, this paper critically analyses more recent and structured approaches that attempt to grasp the complexity of all realities constituting the slum as a key to their management. Then, from a detailed review of properties of slums from literature, it proposes  a rational framework – the Slum Property Map – that organises such properties (cultural, social, economic, environmental into a relationship map where reciprocal links between properties are highlighted and used both to develop narratives of the slum – how it originates, develops and functions for its inhabitants, and in relation to the city- and thus eventually to guide intervention through investment in and management of local assets. The paper presents the Slum Property Map as a comprehensive and dynamic way to understand slums as holding potential for their immediate and future prosperity.

Slum residence and child health in developing countries.

Fink, Günther; Günther, Isabel; Hill, Kenneth

2014-08-01

Continued population growth and increasing urbanization have led to the formation of large informal urban settlements in many developing countries in recent decades. The high prevalence of poverty, overcrowding, and poor sanitation observed in these settlements-commonly referred to as "slums"-suggests that slum residence constitutes a major health risk for children. In this article, we use data from 191 Demographic and Health Surveys (DHS) across 73 developing countries to investigate this concern empirically. Our results indicate that children in slums have better health outcomes than children living in rural areas yet fare worse than children in better-off neighborhoods of the same urban settlements. A large fraction of the observed health differences appears to be explained by pronounced differences in maternal education, household wealth, and access to health services across residential areas. After we control for these characteristics, children growing up in the slums and better-off neighborhoods of towns show levels of morbidity and mortality that are not statistically different from those of children living in rural areas. Compared with rural children, children living in cities (irrespective of slum or formal residence) fare better with respect to mortality and stunting but not with respect to recent illness episodes.

It is generally assumed that urban slum residents have worse health status when compared with other urban populations, but better health status than their rural counterparts. This belief/assumption is often because of their physical proximity and assumed better access to health care services in urban areas. However, a few recent studies have cast doubt on this belief. Whether slum dwellers are better off, similar to, or worse off as compared with rural and other urban populations remain poorly understood as indicators for slum dwellers are generally hidden in urban averages. The aim of this study was to compare health and health-related indicators among slum, rural, and other urban populations in four countries where specific efforts have been made to generate health indicators specific to slum populations. We conducted a comparative analysis of health indicators among slums, non-slums, and all urban and rural populations as well as national averages in Bangladesh, Kenya, Egypt, and India. We triangulated data from demographic and health surveys, urban health surveys, and special cross-sectional slum surveys in these countries to assess differences in health indicators across the residential domains. We focused the comparisons on child health, maternal health, reproductive health, access to health services, and HIV/AIDS indicators. Within each country, we compared indicators for slums with non-slum, city/urban averages, rural, and national indicators. Between-country differences were also highlighted. In all the countries, except India, slum children had much poorer health outcomes than children in all other residential domains, including those in rural areas. Childhood illnesses and malnutrition were higher among children living in slum communities compared to those living elsewhere. Although treatment seeking was better among slum children as compared with those in rural areas, this did not translate to better mortality outcomes. They bear a disproportionately

The aims of the study were to estimate the prevalence of diabetic retinopathy (DR) and enumerate history-based risk factors in the urban slums of Western India. The population-based study was conducted in seven wards of Mumbai urban slums, where we screened 6569 subjects of ≥ 40 years age, with a response rate of 98.4%, for type 2 diabetes mellitus (T2DM) based on American Diabetes Association criteria. All subjects with T2DM underwent dilated 30° seven-field stereo-fundus-photography for DR severity grading based on modified Airlie House classification. A multivariate logistic regression model was used to assess the correlation of DR with the history-based risk factors. The prevalence of DR in the general population of Mumbai urban slums was 1.41% (95% CI 0.59-2.23) and in the T2DM population it was 15.37% (95% CI 8.87-21.87). The positive associations with DR were the longer duration of DM (≥ 11 years: OR, 12.77; 95% CI 2.93-55.61) and male gender (OR, 2.05; 95% CI 1.08-3.89); increasing severity of retinopathy was also significantly associated with longer duration of DM (p Mumbai urban slums. Duration of DM and male gender were significantly associated with DR. The slums in Western India show the trends of urban lifestyle influences similar to the rest of urban India.

THE ETHICAL BORDERS OF SLUM TOURISM IN THE MOBILE CAPITALISM: A CONCEPTUAL DISCUSSION

Full Text Available Though modern nation states appealed to slum-tourism as a valid mechanism towards pacification of slums or violent ghettos, less attention is given to detractors who observe contradictory results. This chapter critically explores the anthropology of poverty to expand the current understanding of slum tourism, the connection of capitalism and poverty as well as problems of policy makers to delineate sustainable programs of development in slums. Far from being a solution for the trouble, slum tourism not only aggravates the situation of exploitation slum-dwellers daily live, but falls in a deep-seated paradox. If poverty turns in the commodity this segment needs or looks, it is almost impossible to reduce the main resource of profits. At time community gains further profits from slum tourism, poverty tends to be replicated

Women's reproductive health in slum populations in India: evidence from NFHS-3.

2010-03-01

The urban population in India is one of the largest in the world. Its unprecedented growth has resulted in a large section of the population living in abject poverty in overcrowded slums. There have been limited efforts to capture the health of people in urban slums. In the present study, we have used data collected during the National Family Health Survey-3 to provide a national representation of women's reproductive health in the slum population in India. We examined a sample of 4,827 women in the age group of 15-49 years to assess the association of the variable slum with selected reproductive health services. We have also tried to identify the sociodemographic factors that influence the utilization of these services among women in the slum communities. All analyses were stratified by slum/non-slum residence, and multivariate logistic regression was used to analyze the strength of association between key reproductive health services and relevant sociodemographic factors. We found that less than half of the women from the slum areas were currently using any contraceptive methods, and discontinuation rate was higher among these women. Sterilization was the most common method of contraception (25%). Use of contraceptives depended on the age, level of education, parity, and the knowledge of contraceptive methods (p women, the proportion of deliveries conducted by skilled attendants was low, and the percentage of home deliveries was high. The use of skilled delivery care was found to be significantly associated with age, level of education, economic status, parity, and prior antenatal visits (p women from slum areas depended on the government facilities for reproductive health services. Our findings suggest that significant differences in reproductive health outcomes exist among women from slum and non-slum communities in India. Efforts to progress towards the health MDGs and other national or international health targets may not be achieved without a focus on the

The objective of this study was to describe the health status of people living in the slums of Nairobi. It was designed as a cross-sectional study based on data from visitors at a clinic at Trnava University located in Mukuru slum in Nairobi. There were about 16,000 visits registered at Mary Immaculate Clinic of Trnava University in Nairobi during 2 years of operation. A random 5% sample was drawn from the paper-card database of this clinic to assess basic characteristics and health complaints of visitors. Both self-reported health complaints and diagnoses written by physicians were used to assess health status of participants. More females with average age (by slum) ranging from 20.46 to 21.30 years than males with average age ranging from (by slum) 15.86 to 19.49 years are the visitors of the clinic. The major self-reported health complaints of visitors were cough, abdominal pain, and headache for both sexes. The most frequent diagnoses were consequently virosis, acute respiratory infections, and bronchitis. Differences in health complaints by slums were observed and are described herein. The major health complaints and diagnoses in addition to the differences in health complaints and diagnoses by slum show that environmental conditions can have major influences on health status. Therefore, environmental improvements are important in the improvement of health status. A very high prevalence of respiratory complaints and gastrointestinal problems signify that improvements in air pollution reduction, drinking water provision, and waste management in slums can lead to more significant and sustainable improvements in health status than just simple treatment. This fact should be taken into account when planning future relief programs

Full Text Available The present paper attempted to study the urbanization in India and condition of urban slums in terms of water, sanitation, electricity, garbage collection and health care, and education which are supposed to be basic minimum needs for the slum dwellers. India is going through the process of rapid urbanization because of industrialization like other third world countries.  The percent of urbanization increase from 27.8 percent in 2001 to 31.1 percent in 2011 census. The increase in the percentage of population in urban areas is because of natural growth, rural to urban migration and the reclassification of village and towns. The share of the slum population in the total urban population of the country was 18.3 percent in 2001 while in 2011 it was 17.4 percent. The condition of urban slums in India is to be improved so as to make them better for living.

Full Text Available Leptospirosis, a spirochaetal zoonotic disease, is the cause of epidemics associated with high mortality in urban slum communities. Infection with pathogenic Leptospira occurs during environmental exposures and is traditionally associated with occupational risk activities. However, slum inhabitants reside in close proximity to environmental sources of contamination, suggesting that transmission during urban epidemics occurs in the household environment.A survey was performed to determine whether Leptospira infection clustered within households located in slum communities in the city of Salvador, Brazil. Hospital-based surveillance identified 89 confirmed cases of leptospirosis during an outbreak. Serum samples were obtained from members of 22 households with index cases of leptospirosis and 52 control households located in the same slum communities. The presence of anti-Leptospira agglutinating antibodies was used as a marker for previous infection. In households with index cases, 22 (30% of 74 members had anti-Leptospira antibodies, whereas 16 (8% of 195 members from control households had anti-Leptospira antibodies. Highest titres were directed against L. interrogans serovars of the Icterohaemorrhagiae serogroup in 95% and 100% of the subjects with agglutinating antibodies from case and control households, respectively. Residence in a household with an index case of leptospirosis was associated with increased risk (OR 5.29, 95% CI 2.13-13.12 of having had a Leptospira infection. Increased infection risk was found for all age groups who resided in a household with an index case, including children <15 years of age (P = 0.008.This study identified significant household clustering of Leptospira infection in slum communities where recurrent epidemics of leptospirosis occur. The findings support the hypothesis that the household environment is an important transmission determinant in the urban slum setting. Prevention therefore needs to target

This paper presents an approach to automated identification of slum area change patterns in Hyderabad, India, using multi-year and multi-sensor very high resolution satellite imagery. It relies upon a lacunarity-based slum detection algorithm, combined with Canny- and LSD-based imagery pre-processing routines. This method outputs plausible and spatially explicit slum locations for the whole urban agglomeration of Hyderabad in years 2003 and 2010. The results indicate a considerable growth of area occupied by slums between these years and allow identification of trends in slum development in this urban agglomeration.

2014-02-01

This study aims to aim to investigate the capability of ENVISAT ASAR satellite and Google Earth data for three-dimensional (3-D) slum urban reconstruction in developed country such as Egypt. The main objective of this work is to utilize 3-D automatic detection algorithm for urban slum in ENVISAT ASAR and Google Erath images were acquired in Cairo, Egypt using Fuzzy B-spline algorithm. The results show that fuzzy algorithm is the best indicator for chaotic urban slum as it can discriminate them from its surrounding environment. The combination of Fuzzy and B-spline then used to reconstruct 3-D of urban slam. The results show that urban slums, road network, and infrastructures are perfectly discriminated. It can therefore be concluded that fuzzy algorithm is an appropriate algorithm for chaotic urban slum automatic detection in ENVSIAT ASAR and Google Earth data.

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 arterial systolic (≥140 mmHg) or diastolic (≥90 mmHg) blood pressure. Sex-specific multivariable models of systolic blood pressure were constructed to identify factors associated with elevated blood pressure. The prevalence of hypertension in the population 18 years and older was 21% (1162/5649). Men had 1.2 times the risk of hypertension compared with women (95% confidence intervals (CI), 1.05, 1.36). Increasing age and lack of any schooling, particularly for women, were also significantly associated with elevated blood pressure (p slum community was lower than reported frequencies in the non-slum population of Brazil and Salvador, yet both disease awareness and treatment frequency were low. Further research on hypertension and other chronic non-communicable diseases in slum populations is urgently needed to guide prevention and treatment efforts in this growing population.

Empowering change: The effects of energy provision on individual aspirations in slum communities

International Nuclear Information System (INIS)

Parikh, Priti; Chaturvedi, Sankalp; George, Gerard

2012-01-01

This paper discusses the role of energy provision in influencing the social aspirations of people living in slums. We examine factors that influence the shift in aspirations in five slum settlements using data from 500 interviews conducted in serviced and non-serviced slums from the state of Gujarat in India. The non-serviced slums did not have access to basic services namely water, sanitation, energy, roads, solid waste and rainwater management. We find empirical evidence which suggests that when basic infrastructure provisions are met, slum dwellers shift their focus from lower order aspirations to the higher order aspirations like health, education, housing and land ownership. We argue that energy provision enhances productivity and enables slum dwellers to shift their aspirations upwards. Furthermore, we test the effect of work days lost due to illness on the relationship between higher order aspirations and aspirations for energy provision. When provision of energy is low, higher work day loss dampens higher order aspirations. For policy makers, this study highlights the critical link between the infrastructure services preferred by slum dwellers and their social aspirations for growth. - Highlights: ► We examine the role of energy provision in influencing social aspirations of people living in slums. ► 500 household interviews conducted in five Indian slum settlements used for the analysis. ► Shift in slum dwellers aspirations from non-serviced to serviced conditions examined using Herzberg’s theory. ► Link between energy provision and higher order aspirations established through a regression model. ► Policy recommendation is to encourage investment in infrastructure services as a driver for development.

2012-04-01

Groundwater in unsewered urban areas is heavily contaminated by onsite sanitation activities and is believed to be an important source of nutrients ex-filtrating into streams and thus contributing to eutrophication of Lakes in urban areas. Currently the fate of nutrients and especially phosphorus leached into groundwater in such areas is not well known. In this study, we undertook an extensive investigation of groundwater in Bwaise slum, Kampala Uganda to understand the distribution and fate of sanitation-related nutrients N and P that are leached into groundwater. Transects of monitoring wells were installed in Bwaise slum and downstream of the slum. From these wells, water levels were measured and water quality analyses done to understand the distribution and composition of the nutrients, how they evolve downstream and the possible subsurface processes affecting their fate during transport. These findings are necessary to evaluate the risk of eutrophication posed by unsewered areas in urban cities and to design/implement sanitation systems that will effectively reduce the enrichment of these nutrients in groundwater. Key words: fate, groundwater, nutrients, processes, slums

Assessing urban sustainability of slum settlements in Bangladesh: Evidence from Chittagong city

2018-04-01

Full Text Available This paper examines the sustainability of urban development through the livelihood conditions of slum dwellers in Bangladesh. The empirical data were collected through interview schedule and FGD from 97 respondents in two slum areas of Bangladesh. The respondents were selected purposively from the second largest city of Bangladesh namely, Chittagong. The results clearly indicate that there exist significant diversity and differences of sustainability indicators, particularly household and housing characteristics, health, drinking water, waste disposal system and security. More specifically, the finding shows that slum dwellers have been experiencing with a wide range of substandard, overcrowded and unhealthy housing conditions in one hand. On the other hand, they have scarce and insufficient health, sanitation, water and waste disposal services which are unswervingly impeding to sustainable development in urban areas. Although the majority of slum dwellers have access to electricity, they are still threatened by the insecurities of women, drug dealing, eviction and natural disaster. Therefore, the findings suggest a holistic approach to address the multi-faceted sustainability issues that affect the livelihoods of slum dwellers within the framework of context-driven development policy of the country.

There is widespread acknowledgement of the need for biodiversity and greening to be part of urban sustainability efforts. Yet we know little about greenery in the context of urban poverty, particularly in slums, which constitute a significant challenge for inclusive development in many rapidly growing cities. We assessed the composition, density, diversity, and species distribution of vegetation in 44 slums of Bangalore, India, comparing these to published studies on vegetation diversity in other land-use categories. Most trees were native to the region, as compared to other land-use categories such as parks and streets which are dominated by introduced species. Of the most frequently encountered tree species, Moringa oleifera and Cocos nucifera are important for food, while Ficus religiosa plays a critical cultural and religious role. Tree density and diversity were much lower in slums compared to richer residential neighborhoods. There are also differences in species preferences, with most plant (herb, shrub and vines) species in slums having economic, food, medicinal, or cultural use, while the species planted in richer residential areas are largely ornamental. Historic development has had an impact on species distribution, with older slums having larger sized tree species, while recent slums were dominated by smaller sized tree species with greater economic and food use. Extensive focus on planting trees and plant species with utility value is required in these congested neighborhoods, to provide livelihood support.

2014-06-01

Full Text Available Background: Urban population growth in developing countries especially in India is at a rapid pace in the past few decades. Growth of urban population is always accompanied by the growth of population in urban slums, which poses threat to the health of urban population, particularly, the health of the children. Objective: The present study aims to study whether the slum dwelling affects the child morbidity, low weight at birth, infant mortality, child malnutrition and anemia.  Methods: Until NFHS-3, there was paucity of data on slums to analyze for a larger area and compare it with non-slum population. However, NFHS-3 provides data from slums in eight cities and is used for the present study. The child health aspects considered here are: prevalence of diarrhea among children, prevalence of fever among children, prevalence of cough among children, infant death, low birth weight, malnutrition among children and anemia among children. Results: Slum children belong to lower socioeconomic strata than children from non-slum areas. Children living in slum areas are 1.3 times, 1.5 times and 1.2 times more likely to suffer from diarrhea, cough and fever respectively than children living in non-slum areas. Multivariate results also showed that slum children have higher odds for low weight at birth (1.4 times and child anemia (1.2 times compared to non-slum children. Conclusion: Slum dwelling children are at a disadvantageous side in terms of child morbidity, anemia and weight at the time of birth.

Spatial approach is one of the main approaches of geography, its analysis emphasizes the existence of space that serves to accommodate human activities. The dynamic development of the city area brings many impacts to the urban community’s own life patterns. The development of the city center which is the center of economic activity becomes the attraction for the community that can bring influence to the high flow of labor both from within the city itself and from outside the city area, thus causing the high flow of urbanization. Urbanization has caused an explosion in urban population and one implication is the occurrence of labor-clumping in major cities in Indonesia. Another impact of the high urbanization flow of cities is the problem of urban settlements. The more populations that come in the city, the worse the quality of the existing settlements in the city if not managed properly. This study aims to determine the location of slum areas in East Wara Sub-Districts using remote sensing technology tools and Geographic Information System (GIS). Parameters used to identify slum areas partially extracted using remote sensing data and for parameters that cannot be extracted using remote sensing data, information obtained from field surveys with information retrieval based on reference data. Analysis results for slum settlements taken from the parameters indicate that the East Wara Sub-District has the largest slum areas located in Pontap village. The village of Pontap has two classes of slums that are very shabby and slums. Slum classes are also in Surutangga Village. The result of the analysis shows that the slum settlement area has 46,324 Ha, which is only located in Pontap Village, whereas for the slum class are found in some villages of Pontap and Surutangga Urban Village, there are 37.797 Ha area. The class of slum settlement areas has the largest proportion of the area among other classes in East Wara Subdistrict. The class of slum settlement areas has an

The epidemic of non-communicable diseases (NCDs) in slums has pushed its residents to heightened vulnerability. The Social Determinants of Health (SDH) framework has been used to understand the social dynamics and impact of NCDs, especially in poorly resourced communities. Whilst the SDH has helped to discredit the characterisation of NCDs as diseases of affluence, its impact on policy has been less definite. Given the multitude of factors that interact in the presentation of NCDs, operationalising the SDH for policies and programmes that account for the contextual complexity of slums has stalled. To organise the complex networks of relations between SDH in slums so as to identify options for Indian municipal policy that are feasible to implement in the short term. The study reviews the literature describing SDH in Indian slums, specifically those that establish causal relations between SDH and NCDs. Root cause analysis was then used to organise the identified relations of SDH and NCDs. Although poverty remains the largest structural determinant of health in slums, the multi-dimensional relations between SDH and NCDs are structured around four themes that describe the dynamics of slums, namely scarce clean water, low education, physical (in)activity and transportation. From the reviewed literature, four logic trees visualising the relations between SDH in slums and NCDs were constructed. The logic trees separate symptomatic problems from their more distal causes, and recommendations were formulated based on features of these relationships that are amenable to policy intervention. Root cause analysis provides a means to focus the lens of examination of SDH, as evidenced here for Indian slums. It provides a guide for the development of policies that are grounded in the actual health concerns of people in slums, and takes account of the complex pathways through which diseases are socially constituted.

Analysing the Great Urban Divide: Turning the Lens to Rural to Understand Slums

Directory of Open Access Journals (Sweden)

Praveen Dhanda

2018-02-01

Full Text Available Instead of looking at slums as strictly ‘urban problems’ requiring ‘urban solutions’, this paper attempts to build a structural link between growth of slums in urban areas and, what can be called, the ‘decay’ of the rural in India. It contends that uneven development of Indian cities with great spatial disparities – made evident by increasing number of slums – is related to uneven development between rural and urban areas. Thus, in order to grapple with the ‘enigma’ of slums, the political economy of rural areas – from where the migrants living in slums ‘originally’ belong – becomes the essential site to engage with. The paper foregrounds the need to study transformations in the rural domain in order to make sense of the growth of slums in cities. In a nutshell, the argument is that the ‘decay’ of the rural and the ‘swelling’ of the city are to be visualised in hyphenated terms since the rural-urban divide is at the heart of the ‘great urban divide’.

A critical challenges in urban aeras is slums. In fact, they are considered a source of crime and disease due to poor-quality housing, unsanitary conditions, poor infrastructures and occupancy security. The poor in the dense urban slums are the most vulnerable to infection due to (i) inadequate and restricted access to safety, drinking water and sufficient quantities of water for personal hygiene; (ii) the lack of removal and treatment of excreta; and (iii) the lack of removal of solid waste. This study aims to investigate the capability of ENVISAT ASAR satellite and Google Earth data for three-dimensional (3-D) slum urban reconstruction in developed countries such as Egypt. The main objective of this work is to utilize some 3-D automatic detection algorithm for urban slum in ENVISAT ASAR and Google Erath images were acquired in Cairo, Egypt using Fuzzy B-spline algorithm. The results show that the fuzzy algorithm is the best indicator for chaotic urban slum as it can discriminate between them from its surrounding environment. The combination of Fuzzy and B-spline then used to reconstruct 3-D of urban slum. The results show that urban slums, road network, and infrastructures are perfectly discriminated. It can therefore be concluded that the fuzzy algorithm is an appropriate algorithm for chaotic urban slum automatic detection in ENVSIAT ASAR and Google Earth data

Slum Conditions in Haryana and Pro-poor Housing Initiatives in Faridabad, India

Directory of Open Access Journals (Sweden)

Nirmala

2017-09-01

Full Text Available Rapid urbanization forces urban poor to live in slums and squatter settlement. In neo-liberal development approach, participatory planning and collaborative actions are becoming popular in slum upgrading programmes. This paper discusses the slum scenario in state of Haryana along with detailed pro-poor housing attempts in industrial city of Haryana i.e. Faridabad. The paper reviews the three projects that aimed to improve the living conditions and lives of urban poor communities in Faridabad. The study examines in detail BSUP projects at Dabua Colony and Bapu Nagar taken up under India’s first urban renewal mission i.e. JNNURM within the context of community participation. Results reveal that contrary to the state’s rhetoric of inclusive governance, the urban poor are completely excluded from settlement planning, leading to a lack of understanding of their needs by the state. BSUP housing scheme has failed to mobilize slum dwellers. Drawing on the experience of these projects, the paper seeks to answer the question: why the stated objectives were not achieved and makes recommendation that community led initiatives and slum mapping should be at the core of slum improvement strategy so that qualitatively superior areas can be planned for the unprivileged.

People living in slums can be considered left behind with regard to national successes in achieving Millennium Development Goals (MDGs). The objective of this study was to evaluate the living and working conditions of waste pickers and their children in a landfill slum located in the largest city in eastern Indonesia. A total of 113 people from the landfill slum and 1184 people from the general population participated in face-to-face interviews. Municipal solid waste (MSW) was analyzed for metals, metalloids and fecal indicator bacteria. Ambient air quality including particulate matter was measured in the landfill. Households in the landfill slum were 5.73 (p=0.04) times more likely to be below the international poverty line (MDG 1: Poverty) and 15.6 times (pIndonesia. Young children living in the landfill slum were 2.87 times (p=0.02) more likely to develop diarrhea than their general population counterparts. Other survey results and environmental measurements suggest that landfill slum children have additional adverse health effects (e.g. infections and poisoning). Poverty underlies several MDG issues that directly or indirectly affect child health. Therefore, eradicating extreme poverty will continue to be the most critical challenge for the MDGs beyond 2015.

Full Text Available Abstract:This Exploration focuses on the emerging field of slum tourism research, which has the potential to connect Latin American and Caribbean studies on tourism and urban inequality. Slum tourism involves transforming poverty, squalor and violence into a tourism product. Drawing on both altruism and voyeurism, this form of tourism is a complex phenomenon that raises various questions concerning power, inequality and subjectivity. This essay seeks to advance the theoretical debate on slum tourism research and to stimulate comparative studies. Introducing brief examples of slum tourism in Mexico and Jamaica, this contribution moves towards an initial theorization of the performance, negotiation and transformation of inequality in a framework of tourism and global mobilities.Resumen: Teorizar el Turismo en las zonas marginadas: Construcción, negociación y transformación de la desigualdadEsta Exploración se centra en el campo emergente del turismo en zonas marginadas, que tiene como potencial conectar a América Latina y el Caribe en los estudios sobre el turismo y la desigualdad urbana.

Handling slum area actually needs to be done not only in slum areas that are part of a metropolitan city or a large town, but it also need to be conducted in the slum areas in the middle city, small town, and coastal areas. A slum generally includes physical condition, socio-economic conditions of cultural communities who live in the settlements, and the impact of both of these conditions. Environmental coastal settlements in Konawe located in the riverside that lead to loss of quality due to environmental stress of the condition of settlement that are not habitable, can be seen from the problems that exist, namely the existence of housing that goes into river body which causes malfunction of watershed river (DAS), and that is prone to flooding. The purpose of this study is to identify slums in coastal settlements in an effort to improve the quality of structured settlements to obtain a picture of the slum in Konawe, to know the problems regarding the existence of slums and future recommendation of the slum settlement in Konawe. Normative analysis was carried out in this research together with quantitative and qualitative description, as well as methods of spatial analysis (spatial). Identification of slum areas was analyzed based on indicators and parameters issued by the Directorate General of Human Settlements. Problems in some districts in Konawe located in the coastal rivers and coastal areas, consist of drainage, disposal of waste water, waste, and the settlement which is not in accordance with the Spatial Konawe. Among those, there are settlements categorized as slums and some are recommended for refurbishment.

A continuous influx of poor people to urban slums poses a challenge to Bangladesh's health system as it has failed to tackle maternal morbidity and mortality. BRAC is the largest non-governmental organisation in Bangladesh. BRAC has been working to reduce maternal, neonatal and under-five children morbidity and mortality of slum dwellers in cities. BRAC has been doing this work for a decade through a programme called MANOSHI. This programme provides door-to-door services to its beneficiaries through community health workers (CHWs) and normal delivery service through its delivery and maternity centres. BRAC started the 'MANOSHI' programme in Narayanganj City Corporation during 2011 to address maternal, neonatal and child health problems facing slum dwellers. We investigated the existing maternal health-service indicators in the slums of Narayanganj City Corporation and compared the findings with a non-intervention area. This cross-sectional study was conducted during 2012, in 47 slums of Narayanganj City Corporation as intervention and 10 slums of Narsingdi Sadar Municipality as comparison area. A total of 1206 married women, aged 15-49 years, with a pregnancy outcome in the previous year were included for interview. Data on socio-demographic characteristics, reproductive and maternal health-care practices like use of contraceptive methods, antenatal care (ANC), delivery care, postnatal care (PNC) were collected through a structured questionnaire. The chi-square test, Student t test, Mann Whitney U-test, factor analysis and log-binominal test were performed by using STATA statistical software for analysing data. The activities of BRAC CHWs significantly improved four or more ANC (47% vs. 21%; pslums compared to comparison slums. Still, about half of the deliveries in both areas were attended at home by unskilled birth attendants, of which a very few received PNC within 48 hours after delivery. The poorest and illiterate women received fewer maternal health services

In India, "non-notified" slums are not officially recognized by city governments; they suffer from insecure tenure and poorer access to basic services than "notified" (government-recognized) slums. We conducted a study in a non-notified slum of about 12,000 people in Mumbai to determine the prevalence of individuals at high risk for having a common mental disorder (i.e., depression and anxiety), to ascertain the impact of mental health on the burden of functional impairment, and to assess the influence of the slum environment on mental health. We gathered qualitative data (six focus group discussions and 40 individual interviews in July-November 2011), with purposively sampled participants, and quantitative data (521 structured surveys in February 2012), with respondents selected using community-level random sampling. For the surveys, we administered the General Health Questionnaire-12 (GHQ) to screen for common mental disorders (CMDs), the WHO Disability Assessment Schedule 2.0 (WHO DAS) to screen for functional impairment, and a slum adversity questionnaire, which we used to create a composite Slum Adversity Index (SAI) score. Twenty-three percent of individuals have a GHQ score≥5, suggesting they are at high risk for having a CMD. Psychological distress is a major contributor to the slum's overall burden of functional impairment. In a multivariable logistic regression model, household income, poverty-related factors, and the SAI score all have strong independent associations with CMD risk. The qualitative findings suggest that non-notified status plays a central role in creating psychological distress-by creating and exacerbating deprivations that serve as sources of stress, by placing slum residents in an inherently antagonistic relationship with the government through the criminalization of basic needs, and by shaping a community identity built on a feeling of social exclusion from the rest of the city.

To analyze small intestinal bacterial overgrowth in school-aged children and the relationship between hydrogen and methane production in breath tests. This transversal study included 85 children residing in a slum and 43 children from a private school, all aged between 6 and 10 years, in Osasco, Brazil. For characterization of the groups, data regarding the socioeconomic status and basic housing sanitary conditions were collected. Anthropometric data was obtained in children from both groups. All children completed the hydrogen (H(2)) and methane (CH(4)) breath test in order to assess small intestinal bacterial overgrowth (SIBO). SIBO was diagnosed when there was an increase in H(2) ≥ 20 ppm or CH(4) ≥ 10 ppm with regard to the fasting value until 60 min after lactulose ingestion. Children from the slum group had worse living conditions and lower nutritional indices than children from the private school. SIBO was found in 30.9% (26/84) of the children from the slum group and in 2.4% (1/41) from the private school group (P = 0.0007). Greater hydrogen production in the small intestine was observed in children from the slum group when compared to children from the private school (P = 0.007). A higher concentration of hydrogen in the small intestine (P slum group with SIBO when compared to children from the slum group without SIBO. Methane production was observed in 63.1% (53/84) of the children from the slum group and in 19.5% (8/41) of the children from the private school group (P slum. Colonic production of hydrogen was lower in methane-producing children (P = 0.017). Children who live in inadequate environmental conditions are at risk of bacterial overgrowth and methane production. Hydrogen is a substrate for methane production in the colon.

Objectives This research studies the role of slums in the spread and control of infectious diseases in the National Capital Territory of India, Delhi, using detailed social contact networks of its residents. Methods We use an agent-based model to study the spread of influenza in Delhi through person-to-person contact. Two different networks are used: one in which slum and non-slum regions are treated the same, and the other in which 298 slum zones are identified. In the second network, slum-specific demographics and activities are assigned to the individuals whose homes reside inside these zones. The main effects of integrating slums are that the network has more home-related contacts due to larger family sizes and more outside contacts due to more daily activities outside home. Various vaccination and social distancing interventions are applied to control the spread of influenza. Results Simulation-based results show that when slum attributes are ignored, the effectiveness of vaccination can be overestimated by 30%–55%, in terms of reducing the peak number of infections and the size of the epidemic, and in delaying the time to peak infection. The slum population sustains greater infection rates under all intervention scenarios in the network that treats slums differently. Vaccination strategy performs better than social distancing strategies in slums. Conclusions Unique characteristics of slums play a significant role in the spread of infectious diseases. Modelling slums and estimating their impact on epidemics will help policy makers and regulators more accurately prioritise allocation of scarce medical resources and implement public health policies.

Shekhar, S.

2012-07-01

We have been witnessing a gradual and steady transformation from a pre dominantly rural society to an urban society in India and by 2030, it will have more people living in urban than rural areas. Slums formed an integral part of Indian urbanisation as most of the Indian cities lack in basic needs of an acceptable life. Many efforts are being taken to improve their conditions. To carry out slum renewal programs and monitor its implementation, slum settlements should be recorded to obtain an adequate spatial data base. This can be only achieved through the analysis of remote sensing data with very high spatial resolution. Regarding the occurrences of settlement areas in the remote sensing data pixel-based approach on a high resolution image is unable to represent the heterogeneity of complex urban environments. Hence there is a need for sophisticated method and data for slum analysis. An attempt has been made to detect and discriminate the slums of Pune city by describing typical characteristics of these settlements, by using eCognition software from quick bird data on the basis of object oriented approach. Based on multi resolution segmentation, initial objects were created and further depend on texture, geometry and contextual characteristics of the image objects, they were classified into slums and non-slums. The developed rule base allowed the description of knowledge about phenomena clearly and easily using fuzzy membership functions and the described knowledge stored in the classification rule base led to the best classification with more than 80% accuracy.

Gender differentials and old age survival in the Nairobi slums, Kenya.

This paper examines gender differentials in survival amongst older people (50+ years) in the Nairobi slums and to the best of our knowledge is the first study of its kind in an urban African setting. The results provide evidence contrary to the expected paradox of poorer self-rated health yet better survival amongst older women. Older women in the Nairobi slums have poorer self-rated health and poorer circumstances across other factors, including disability and socio-economic status. Further, older women in the slums do not have better survival. The conventional female advantage in mortality only becomes apparent after accounting for the cumulative influence of individual characteristics, social networks, health and socio-economic status, suggesting the female advantage in unadjusted old-age mortality does not apply to contexts where women experience significant disadvantage across multiple life domains. This highlights the urgent need to redress the support, status and opportunities available for women across the life course in contexts such as the Nairobi slums. In addition, a greater number of factors differentiate mortality risk amongst men than amongst women, suggesting inequality amongst slum dwelling older men and highlighting the need for gender sensitive interventions which account for the particular needs of both genders in old age.

2012-03-01

Full Text Available Abstract Background Urban health is of global concern because the majority of the world's population lives in urban areas. Although mental health problems (e.g. depression in developing countries are highly prevalent, such issues are not yet adequately addressed in the rapidly urbanising megacities of these countries, where a growing number of residents live in slums. Little is known about the spectrum of mental well-being in urban slums and only poor knowledge exists on health promotive socio-physical environments in these areas. Using a geo-epidemiological approach, the present study identified factors that contribute to the mental well-being in the slums of Dhaka, which currently accommodates an estimated population of more than 14 million, including 3.4 million slum dwellers. Methods The baseline data of a cohort study conducted in early 2009 in nine slums of Dhaka were used. Data were collected from 1,938 adults (≥ 15 years. All respondents were geographically marked based on their households using global positioning systems (GPS. Very high-resolution land cover information was processed in a Geographic Information System (GIS to obtain additional exposure information. We used a factor analysis to reduce the socio-physical explanatory variables to a fewer set of uncorrelated linear combinations of variables. We then regressed these factors on the WHO-5 Well-being Index that was used as a proxy for self-rated mental well-being. Results Mental well-being was significantly associated with various factors such as selected features of the natural environment, flood risk, sanitation, housing quality, sufficiency and durability. We further identified associations with population density, job satisfaction, and income generation while controlling for individual factors such as age, gender, and diseases. Conclusions Factors determining mental well-being were related to the socio-physical environment and individual level characteristics. Given that

How do slums change the relationship between urbanization and the carbon intensity of well-being?

Directory of Open Access Journals (Sweden)

Julius Alexander McGee

Full Text Available This study examines how the relationship between urbanization (measured as the percentage of total population living in urban areas and the carbon intensity of well-being (CIWB (measured as a ratio of carbon dioxide emissions and life expectancy in most nations from 1960-2013 varies based on the economic context and whereabouts of a substantial portion of a nation's urban population. To accomplish this, we use the United Nations' (UN definition of slum households to identify developing countries that have substantial slum populations, and estimate a Prais-Winsten regression model with panel-corrected standard errors (PCSE, allowing for disturbances that are heteroskedastic and contemporaneously correlated across panels. Our findings indicate that the rate of increase in CIWB for countries without substantial slum populations begins to slow down at higher levels of urbanization, however, the association between urbanization and CIWB is much smaller in countries with substantial slum populations. Overall, while urbanization is associated with increases in CIWB, the relationship between urban development and CIWB is vastly different in developed nations without slums than in under-developed nations with slums.

Undernutrition remains the largest contributor to the global disease burden. Different factors affecting the nutritional status of children need to be studied to determine those to be targeted in a country like Nigeria, characterized by widespread poverty and inequitable distribution of wealth. This study was aimed at ascertaining the relationship between prevailing socioeconomic and environmental factors, and the nutritional status of children residing in a typical urban slum. A cross-sectional descriptive study of 788 children aged 6-12 years selected by stratified, multistage random sampling method from public primary schools in slum and non-slum areas of Onitsha was carried out. Their nutritional status was determined using anthropometric measures. The socioeconomic and environmental variables of interest were analyzed to determine their relationship with undernutrition in the children. Socioeconomic status was the major determinant of nutritional status in this study. Poor housing also affected the nutritional status of the slum children who were significantly from poorer families than those residing in non-slum areas (χ2 = 66.69, P = 0.000). This study highlights the need for an effective nutrition program targeted at school children in urban slums surrounded by factors predisposing them to undernutrition.

Policy directions in urban health in developing countries--the slum improvement approach.

The urban development, or housing, sector has a longer experience of addressing the problems of the urban poor in developing countries than the health sector. In recent years the policy of 'slum improvement', which involves both sectors, has attracted the support of international donors. This article documents the development of the slum improvement approach and addresses key issues of the approach which have implications for health planning: covering the poorest dwellers; relocation; land tenure; gentrification; debt burdens and the impact on women. Questions about the approach which still need answering are defined and a summary of the constraints in slum improvement and potential solutions is presented.

Full Text Available Background: : Slum dwellers are likely to be among the most deprived people in urban areas. Poor hygiene practices and inadequate sanitary conditions play major roles in the increased burden of communicable diseases within developing countries like ours. Objective: To assess the knowledge and practice about personal hygiene and environmental sanitation in selected slums of Dhaka city. Materials and method: This cross sectional study was conducted in purposively selected urban slum areas of Moghbazar slum, Bashabo slum and T&T slum of Dhaka city during February 2014 to April 2014. Convenient sampling technique was applied. Semi-structured pre-tested questionnaire was used and face to face interview was conducted. Total 475 subjects, irrespective of age and sex, were included in this study. Results: Out of 475 respondents, more than fifty percent slum dwellers resided in tin shaded room while 21.7% in ‘kacha’ houses. Sixty six percent of the respondents used to drink water from tube-well and 24% used supplied water provided by the city corporation. The study revealed that near 59% of the respondents used sanitary latrine. About 67% slum dwellers regularly practiced hand washing before taking meal and 59.2% respondents used soap after defecation. About fifty percent respondents brushed their teeth regularly with tooth paste. Regarding personal cleanliness, 81% subjects took bath regularly while 78% washed clothes irregularly. A statistically significant relation was found between washing of hands before meal (p=0.001, washing of hands after defecation (p=0.02, tooth brushing (p=0.001, bathing (p=0.009, washing of cloths (p=0.001, use of footwear (p=0.63 with knowledge of personal hygiene of the slum dwellers. Conclusion: Continuous community hygiene education along with adequate access to water supply and sanitation improves hygiene behaviour and policy makers and health care providers should have definite strategy and implementation.

Social determinants of health in selected slum areas in Jordan: challenges and policy directions.

Ajlouni, Musa T

2016-01-01

The unplanned urbanization in Jordan has over time created many informal settlements "slums" around big cities as Amman, Zerka and Aqaba. The purpose of this study was to highlight the most common challenges related to social determinants of health in two selected slum areas in Amman and Aqaba and suggest policy directions and interventions to meet these challenges. In addition to a prestructured interview with all household heads living in the two slum sites, focus group meetings with a purposefully selected sample of 12 slum dwellers in each site were used to assess the structural and intermediary determinants of health as perceived by slum residents in the two study locations. The study found that slum residents in the two locations suffer from many challenges as severe poverty; unemployment; illiteracy and low education attainments; gender discrimination; insufficient and poor diet; social and official exclusion; unhealthy environment; lack of water supply, electricity and basic sanitation facilities; high prevalence of diseases; and insufficient and inappropriate health services. Specific policy directions to meet these challenges were recommended and grouped into three main clusters: social protection, social inclusion and empowerment. New plans and tools should be developed by local authorities in Jordan to understand, protect, include and empower those vulnerable people who are forced to live in these unhealthy and inhuman environments.

One largely unstudied benefit of relocating families from slums to public housing is the potential improvement in indoor air quality (IAQ). We compared families that moved from slums to public housing with those that remained living in slums in Santiago, Chile in terms of fine particulate matter (PM2.5) as main indicator of change. A cross-sectional study of 98 relocated families and 71 still living in slums was carried out, obtaining indoor and outdoor samples by a Personal Environmental Monitor. Home characteristics, including indoor air pollution sources were collected through questionnaires. Multivariate regression models included the intervention (public housing or slum), indoor pollution sources, outdoor PM2.5 and family characteristics as predictors. Indoor PM2.5 concentrations were higher in slums (77.8 μg m-3 [SD = 35.7 μg m-3]) than in public housing (55.7 μg m-3 [SD = 34.6 μg m-3], p slum houses. The multivariate analysis showed that housing intervention significantly decreased indoor PM2.5 (10.4 μg m-3) after adjusting by the other predictors. Outdoor PM2.5 was the main predictor of indoor PM2.5. Other significant factors were water heating fuels and indoor smoking. Having infants 1-23 months was associated with a lowering of indoor PM2.5. Our results suggest that a public housing program that moves families from slums to public housing improves indoor air quality directly and also indirectly through air pollution sources.

In their own words: assessment of satisfaction with residential location among migrants in Nairobi slums.

2011-06-01

Using qualitative data collected from a sample of rural-urban migrants over the age of 15 in two Nairobi slums interviewed in 2008, this paper discusses the migrants' extent of satisfaction with their residential location and decision to migrate. The study sheds light on why people continue to migrate to, and stay in, the rapidly growing slum settlements despite the high levels of poverty and poor health conditions in these areas. Tenure status is related to satisfaction for all ages. Environmental factors were frequently mentioned as a source of dissatisfaction. Life cycle and 'age-cohort effects' may also affect satisfaction for different age groups in terms of who is satisfied as well as the issues that are considered for satisfaction. High levels of dissatisfaction with slum life may be responsible for high out-migration in slum areas, although it does not mean that those who remain do so because they are satisfied. At the same time, challenges associated with slum life do not automatically signify dissatisfaction. Perceived success, as well as conditions in the area of origin can be used to explain and understand satisfaction/dissatisfaction with slum life. Satisfaction with migration and residential location may be related not only to the destination place, but also to events in the area of origin.

2016-04-01

Full Text Available The cancerous spread of slum has been a rampant problem in urban areas worldwide. The acute shortage of housing facilities compels the poor to live in slums. Proper rehabilitation is considered as a very essential remedial measure to provide better living environment to slum peoples. This study is an essential attempt to gauge the effectiveness of a rehabilitation program, which studies the changes in socio-economic and health condition of rehabilitated slum dwellers since they got rehabilitated. In order to do so, a household survey was carried comprising 240 households in two rehabilitated sites in the city of Kolkata (ward no. 107 and 114 during the month of July, 2014. The results conforms a strand of a belief that in-situ rehabilitation or rehabilitation within short distance is more effective. A rehabilitation too far away area disrupts the existing social, economic and political ties of neighborhoods. Measures have also been proposed to overcome such problems and to make the slum dwellers an integral part of urban society.

Full Text Available Introduction: Humans have been using substances in one form or the other for centuries. Adolescents seem to be the most vulnerable group, and the slum dwellers are particularly at risk because of the prevailing environment. Objectives: The objective of this study is to study the prevalence of substance use among adolescents of slums of Guwahati city and to find out various factors influencing substance use among them. Materials and Methods: A cross-sectional study was conducted among the adolescents living in slums of Guwahati, Assam, from February to May 2014. Using cluster sampling method, 23 slums were selected, and desired clusters were obtained by applying probability proportionate to size method. From each slum, equal number of boys and girls were interviewed to get a total of 414 study subjects. Statistical Analysis: Proportions, Chi-square test, and binary logistic regression were used. Results: The prevalence of ever users was 37.68% and 35.02% were current users. Gutkha was the most common substance used. The mean age of initiation of abusive substances was around 12 years for both boys and girls. Age, sex, religion, caste, schooling status, occupation, living status of parents and respondents, peer usage, and relationship with the family members showed significant association with substance use. Binary logistic regression concluded that age group, sex, and peer usage were the most significant factors influencing substance use behavior. Conclusion: As increasing age and peer usage influenced the substance usage, peer group counseling, recreational activities, and skill development programs in the early years hold promising in curbing the problem.

The study aimed to identify the important effects of some selected variables in antenatal care (ANC) seeking behaviour among slum mothers. The data for the study were collected in 2006 from 700 mothers in the slum areas of Rajshahi City Corporation (RCC), Bangladesh. The results indicate that tetanus toxoid (TT) is relatively widespread in slum areas of RCC. Serious health implications were observed for the mothers and their children who lived in the study areas because more than half of the respondents (56.1%) were not assisted at their last childbirth by any health professional. The respondents were too poor to buy iron tablets/syrup and vitamin tablets/syrup during their last pregnancy. The application of a logistic regression model suggested that demographic and socio-economic factors were associated with ANC seeking behaviour among slum mothers. Respondents' education, place of treatment, husband's occupation, family's income, and exposure to mass media had highly significant effects on mothers seeking medical checkups during their last pregnancy.

People living in slums can be considered left behind with regard to national successes in achieving Millennium Development Goals (MDGs). The objective of this study was to evaluate the living and working conditions of waste pickers and their children in a landfill slum located in the largest city in eastern Indonesia. A total of 113 people from the landfill slum and 1184 people from the general population participated in face-to-face interviews. Municipal solid waste (MSW) was analyzed for metals, metalloids and fecal indicator bacteria. Ambient air quality including particulate matter was measured in the landfill. Households in the landfill slum were 5.73 (p = 0.04) times more likely to be below the international poverty line (MDG 1: Poverty) and 15.6 times (p < 0.01) more likely to have no one in the household possessing a primary education (MDG 2: Universal Education), and 107 times (p < 0.01) more likely not to have improved sanitation facilities (MDG 7: Environmental Sustainability) when compared to the general population. Diarrhea is one of the leading causes of death in children under five in Indonesia. Young children living in the landfill slum were 2.87 times (p = 0.02) more likely to develop diarrhea than their general population counterparts. Other survey results and environmental measurements suggest that landfill slum children have additional adverse health effects (e.g. infections and poisoning). Poverty underlies several MDG issues that directly or indirectly affect child health. Therefore, eradicating extreme poverty will continue to be the most critical challenge for the MDGs beyond 2015. - Highlights: • Waste-pickers and the health and well-being of their children are examined • Landfill slum (LS) residents do not have a share in improving economies • LSs illustrate the interrelationship of Millennium Development Goals • LS mothers and children are exposed to toxic chemicals and pathogens • MDGs directly and indirectly addresses issues

A cross-sectional survey, using cluster sampling technique, of slum population, was done to explore the oral health status and the prevalence of common oral diseases. A close ended questionnaire comprising Decayed, Missing and Filled Teeth (DMFT) Index, Gingival Index (Löe and Silness) and Plaque Index was applied to evaluate and record oral diseases, in both male and female population, covering a wide range of age groups. Clinical examination was carried out in different shum set ups, including slum schools by trained and calibrated examiners. Three thousand nine hundred and four (3904) slum dwellers participated in the survey. Prevalence of Caries was expressed in mean DMFT, recording of gingival status followed the method of Löe and Silness, oral hygiene status was evaluated using Plaque index. Mean decayed component, of the DMFT, was significantly higher than filling and missing component. Both decayed and missing components showed increasing trend, and filling components decreased as the age progressed. Prevalence of gingivitis and plaque accumulation was remarkably high among slum dwellers. Significantly high level of common oral diseases was found among Tongi slum dwellers.

Catastrophic health expenditure and its determinants in Kenya slum communities.

In Kenya, where 60 to 80% of the urban residents live in informal settlements (frequently referred to as slums), out-of-pocket (OOP) payments account for more than a third of national health expenditures. However, little is known on the extent to which these OOP payments are associated with personal or household financial catastrophe in the slums. This paper seeks to examine the incidence and determinants of catastrophic health expenditure among urban slum communities in Kenya. We use a unique dataset on informal settlement residents in Kenya and various approaches that relate households OOP payments for healthcare to total expenditures adjusted for subsistence, or income. We classified households whose OOP was in excess of a predefined threshold as facing catastrophic health expenditures (CHE), and identified the determinants of CHE using multivariate logistic regression analysis. The results indicate that the proportion of households facing CHE varies widely between 1.52% and 28.38% depending on the method and the threshold used. A core set of variables were found to be key determinants of CHE. The number of working adults in a household and membership in a social safety net appear to reduce the risk of catastrophic expenditure. Conversely, seeking care in a public or private hospital increases the risk of CHE. This study suggests that a substantial proportion of residents of informal settlements in Kenya face CHE and would likely forgo health care they need but cannot afford. Mechanisms that pool risk and cost (insurance) are needed to protect slum residents from CHE and improve equity in health care access and payment.

No land in sight : impact of caste on slum communities' access to land in Bangalore, India

OpenAIRE

Narayana, Rakesh

2012-01-01

This study examines the impact of caste on slum communities’ access to urban land in Bangalore, India. Historically, pattern of land ownership in India was inextricably melded together with caste wherein the dominant castes owned land and excluded Dalits from land access. Slums can be seen as primarily an urban land access issue. A majority of slum residents in Bangalore are Dalits though they form a minority in the overall population. The study adopts a Social Exclusion paradigm to understan...

Surakarta is a rapidly urbanized city and it causes the limitation of the availability of land within its urban area. This entangled problem is resulting in the development of slum settlements that spread across the city. One of the slum concentration areas is located on Pepe riverbanks downstream area that belongs to Kampung Sangkrah administrative boundaries. Slum settlements are characterized as a densely-populated area lacking of, or absence of, open space. This condition forces slum inhabitants to effectively use their available spaces, even multi-functionally. This research aims to observe how slum inhabitants multi-functionally use the spaces around their houses and determine the typology of multifunctional space and also the factors that influence it. To understand this phenomenon, this research used activity pattern perspectives. The scope of observation covers in-house (internal) space utilizations and neighborhood-level (external) space utilization. The data used for this research were collected primarily through site observations and interviews, using sampling to conduct data collection for in-house activities and space utilization. The analysis was conducted using descriptive method qualitatively. The research concluded that there are three types of multifunctional space utilization within slum settlements, and the utilization of spaces, whether internal or external utilization also varies depending on the inhabitants' economic-related activities.

Parkar, Shubhangi R; Fernandes, Johnson; Weiss, Mitchell G

2003-12-01

Urban mental health programmes in developing countries remain in their infancy. To serve low-income communities, research needs to consider the impact of common life experience in slums, including poverty, bad living conditions, unemployment, and crowding. Our study in the Malavani slum of Mumbai examines afflictions of the city affecting the emotional well-being and mental health of women and men with respect to gender. This is a topic for which mental health studies have been lacking, and for which psychiatric assumptions based on middle-class clinical experience may be most tenuous. This study employs ethnographic methods to show how environmental and social contexts interact in shaping local experience with reference to common mental health problems. Focusing on the social and environmental context of the mental health of communities, rather than psychiatric disorders affecting individuals, findings are broadly applicable and sorely needed to guide the development of locally appropriate community mental health programmes. Identified afflictions affecting mental health include not only access to health care, but also sanitation, addictions, criminality, domestic violence, and the so-called bar-girl culture. Although effective clinical interventions are required for mental health services to treat psychiatric disorders, they cannot directly affect the conditions of urban slums that impair mental health.

Telaga Tujuh village is the only island inhabited compared to other islands in Langsa City, Aceh. Most of the houses are on stilts with very limited infrastructure such as lack of road facilities, local drainage, drinking water, wastewater, and garbage disposals. In determining the model of the slum settlements arrangement of Telaga Tujuh Village, there are some things to know that the characteristics of slums themselves and the causes of slum settlement. The aim of this study is to determine model of slum settlement arrangement that is suitable to be applied in the location. The method used is qualitative with sampling technique and qualitative analysis. To obtain the primary data used observation method, questionnaires, and interview. Secondary data obtained from agencies related to slum settlement arrangement. Based on characteristic analysis found that 365 residential buildings are irregular with the percentage of 100%, 365 residential buildings do not have safe drinking water supply, 365 residential buildings do not have waste water management. From the analysis shows that the appropriate model to be applied to Telaga Tujuh village is the rejuvenation model with the land consolidation system through the re-arrangement divided by two, 60% for the existing residential development and 40% for commercial development.

Do slums matter? Location and early childhood preventive care choices among urban residents of Bangladesh.

Science.gov (United States)

Heller, Lauren R

2013-10-01

Upward trends in the relative proportions of slum residents in developing countries have led to widespread concern regarding the impact of slum residency on health behaviors. Measurement of these impacts requires recognizing that unobservable household characteristics that affect the location decision may also affect health care choices and outcomes. To address the potential for bias, this paper models the location decision and the household's demand for maternal and child health services simultaneously using a flexible, semi-parametric approach. It uses a unique urban data set from Bangladesh that incorporates sophisticated geographical mapping techniques to carefully delineate between slum and non-slum areas at a particular point in time. The results suggest that accounting for the endogenous location decision of a family substantially reduces bias in estimated marginal effects of slum residence on preventive care demand. While community infrastructure variables appear correlated with preventive care demand, the causal effect of the availability of primary health care facilities is indistinguishable from zero when unobserved heterogeneity is taken into account. The findings suggest that improvements in community infrastructure in urban areas of developing countries are a more favorable health policy solution at the margin than the construction of additional health care facilities.

Urbanization is occurring at a rapid pace, especially in low-income countries. Dhaka, Bangladesh, is estimated to grow to 50 million by 2015, with 21 million living in urban slums. Although health services are available, neonatal mortality is higher in slum areas than in urban non-slum areas. The Manoshi program works to improve maternal, newborn, and child health in urban slums in Bangladesh. This paper describes newborn care practices in urban slums in Dhaka and provides program recommendations. A quantitative baseline survey was conducted in six urban slum areas to measure newborn care practices among recently delivered women (n = 1,256). Thirty-six in-depth semi-structured interviews were conducted to explore newborn care practices among currently pregnant women (n = 18) and women who had at least one delivery (n = 18). In the baseline survey, the majority of women gave birth at home (84%). Most women reported having knowledge about drying the baby (64%), wrapping the baby after birth (59%), and cord care (46%). In the in-depth interviews, almost all women reported using sterilized instruments to cut the cord. Babies are typically bathed soon after birth to purify them from the birth process. There was extensive care given to the umbilical cord including massage and/or applying substances, as well as a variety of practices to keep the baby warm. Exclusive breastfeeding was rare; most women reported first giving their babies sweet water, honey and/or other foods. These reported newborn care practices are similar to those in rural areas of Bangladesh and to urban and rural areas in the South Asia region. There are several program implications. Educational messages to promote providing newborn care immediately after birth, using sterile thread, delaying bathing, and ensuring dry cord care and exclusive breastfeeding are needed. Programs in urban slum areas should also consider interventions to improve social support for women, especially first time mothers. These

Full Text Available Introduction: Education plays a vital role to developing a nation. In India, urban slums constituting about 22.6% of the urban population are the poor and socially disadvantaged. This slum community is least concerned for school enrolment of their children inspite of the fact that primary education is compulsory and is free in public schools. In urban areas schools available are mostly of private sector that are not free and beyond affordability to slums; government and corporation schools are few, but beyond reach. Motive of the parents is to involve children in income generating activities and the girls are more deprived of school enrolment in poorer society. Objectives: 1 assess the enrolment status of slum children and 2 determine the factors influencing school enrolment.Methodology: The data was collected during 2011-12 from 15 randomly selected slums out of 227 in which a total of 893 families were contacted and mothers with children aged 5-15 years interrogated. In addition to child history on age, sex and school enrolment, the family background characteristics were e.g. religion, caste, and family size as well as age, education and occupation of both mother & father were recorded.Results: Out of 1145 children, male and female equal represented; mostly (90.9% were Hindus and half were SC/ST class. About 30% father and 57.2% mothers were illiterate; about half fathers were unskilled-worker and 96.0% mother’s house wife. Overall 31.3% children were not enrolled and were decreasing from 49.2% to 24.3% to 21.4% in the age groups 5-6, 7-9 and 10-15 years respectively. Enrolment was poor in Muslims (50.0% compared to Hindus (29.4%; enrolment was similar irrespective of child sex among Hindus, but in Muslims 62.5% male and 35.4% female children were only enrolled. Similar was the situation as one move from SC/ST (67.6% to OBC (73.4% and general caste (77.9%. Education of father and mother had significant role to enrolment but not the age and

Rapid urbanization has led to the growth of urban slums and increased healthcare burdens for vulnerable populations. Electronic Medical Records (EMRs) have the potential to improve continuity of care for slum residents, but their implementation is complicated by technical and non-technical limitations. This study sought practical insights about facilitators and barriers to EMR implementation in urban slum environments. Descriptive qualitative method was used to explore staff perceptions about a recent open-source EMR deployment in two primary care clinics in Kibera, Nairobi. Participants were interviewed using open-ended, semi-structured questions. Content analysis was used when exploring transcribed data. Three major themes - systems, software, and social considerations - emerged from content analysis, with sustainability concerns prevailing. Although participants reported many systems (e.g., power, network, Internet, hardware, interoperability) and software (e.g., data integrity, confidentiality, function) challenges, social factors (e.g., identity management, training, use incentives) appeared the most important impediments to sustainability. These findings are consistent with what others have reported, especially the importance of practical barriers to EMR deployments in resource-constrained settings. Other findings contribute unique insights about social determinants of EMR impact in slum settings, including the challenge of multiple-identity management and development of meaningful incentives to staff compliance. This study exposes front-line experiences with opportunities and shortcomings of EMR implementations in urban slum primary care clinics. Although the promise is great, there are a number of unique system, software and social challenges that EMR advocates should address before expecting sustainable EMR use in resource-constrained settings.

Rashid, Sabina Faiz

2009-08-01

The health and rights of populations living in informal or slum settlements are key development issues of the twenty-first century. As of 2007, the majority of the world's population lives in urban areas. More than one billion of these people, or one in three city-dwellers, live in inadequate housing with no or a few basic resources. In Bangladesh, urban slum settlements tend to be located in low-lying, flood-prone, poorly-drained areas, having limited formal garbage disposal and minimal access to safe water and sanitation. These areas are severely crowded, with 4-5 people living in houses of just over 100 sq feet. These conditions of high density of population and poor sanitation exacerbate the spread of diseases. People living in these areas experience social, economic and political exclusion, which bars them from society's basic resources. This paper overviews policies and actions that impact the level of exclusion of people living in urban slum settlements in Bangladesh, with a focus on improving the health and rights of the urban poor. Despite some strategies adopted to ensure better access to water and health, overall, the country does not have a comprehensive policy for urban slum residents, and the situation remains bleak.

TIPOLOGI DAN POLA PENANGANAN PERMUKIMAN KUMUH DI KOTA BONTANG (The Typology and Patterns of Slum Improvement Management in Bontang City

Directory of Open Access Journals (Sweden)

2014-11-01

Full Text Available Started as a fishing settlement area in Bontang Kuala Village, the City of Bontang has been growing very rapidly. However, despite this growth people's standard of living has been decreasing in terms of environmental quality, income as well as sheltering with the emergence of slum areas. These conditions greatly affect the physical, social, cultural and economic aspects of life. The management of slum areas in Bontang City becomes strategic because slums are integrated with the rest of the city including the downtown area and urban growth centers, as well as with the other areas in the vicinity, such as industrial, commercial, warehousing, and office areas. Therefore, it is necessary to identify the characteristics of the slum areas. The identification methods do not discriminate the distribution of slum areas. The criteria used include non-economic vitality, regional economic vitality, land ownership status, infrastructure and facility conditions, local government’s commitment, and handling priorities. Environmental assessment of the slums was done by assigning a weighting system to each of the above criteria. The determination of the weights of the criteria is relative and depends on the individual and group preferences in looking at the influence of each criterion. The improvement or treatment patterns appropriate to be applied in Bontang City should be in accordance with the site characteristics. Locations with high-scale slum category (HS requires the curative pattern while those with moderate category (MS should take reductive treatment, and slum areas with low-scale category (LS will require preventive treatment.

Leptospirosis disproportionately affects residents of urban slums. To understand the knowledge, attitudes, and practices regarding leptospirosis, we conducted a cross-sectional study among residents of an urban slum community in Salvador, Brazil. Of the 257 residents who were interviewed, 225 (90%) were aware of leptospirosis and more than two-thirds of respondents correctly identified the modes of disease transmission and ways to reduce exposure. However, study participants who performed risk activities such as cleaning open sewers had limited access to protective clothing such as boots (33%) or gloves (35%). Almost all respondents performed at least one activity to prevent household rat infestation, which often included use of an illegal poison. Our findings support the need for interventions targeted at the individual and household levels to reduce risk of leptospirosis until large-scale structural interventions are available to residents of urban slum communities.

Toward “Age-Friendly Slums”? Health Challenges of Older Slum Dwellers in Nairobi and the Applicability of the Age-Friendly City Approach

Aboderin, Isabella; Owii, Hilda Akinyi

2017-01-01

A majority of urban residents in sub-Saharan Africa (SSA) and other developing regions live in informal settlements, or slums. Much of the discourse on slum health centres on younger generations, while an intensifying agenda on healthy ageing as yet lacks a systematic focus on slums. Similarly, the global age-friendly cities (AFC) movement does not, thus far, extend to slums. This paper examines the particular challenges that a slum-focused age-friendly initiative in SSA may need to address, and the relevance of present AFC indicators and domains for initiatives to advance the health and well-being of older slum dwellers. The analysis builds on the case of two slum communities in Nairobi, Kenya. It analyzes two bodies of relevant evidence from these settlements, namely on the health and social circumstances of older residents, and on the local application and measurement of AFC indicators. The findings point to a set of unsurprising, but also less obvious, core health and social adversities that an age-friendly initiative in such settlements would need to consider. The findings show, further, that the current AFC domains and indicators framework only partly capture these adversities, but that there is potential for adapting the framework to be meaningful for slum settings. The paper concludes by underscoring the need for, and opportunities inherent in, the pursuit of an “age-friendly slums” initiative going forward. PMID:29053576

Impact of environment and social gradient on Leptospira infection in urban slums.

2008-04-01

Full Text Available Leptospirosis has become an urban health problem as slum settlements have expanded worldwide. Efforts to identify interventions for urban leptospirosis have been hampered by the lack of population-based information on Leptospira transmission determinants. The aim of the study was to estimate the prevalence of Leptospira infection and identify risk factors for infection in the urban slum setting.We performed a community-based survey of 3,171 slum residents from Salvador, Brazil. Leptospira agglutinating antibodies were measured as a marker for prior infection. Poisson regression models evaluated the association between the presence of Leptospira antibodies and environmental attributes obtained from Geographical Information System surveys and indicators of socioeconomic status and exposures for individuals. Overall prevalence of Leptospira antibodies was 15.4% (95% confidence interval [CI], 14.0-16.8. Households of subjects with Leptospira antibodies clustered in squatter areas at the bottom of valleys. The risk of acquiring Leptospira antibodies was associated with household environmental factors such as residence in flood-risk regions with open sewers (prevalence ratio [PR] 1.42, 95% CI 1.14-1.75 and proximity to accumulated refuse (1.43, 1.04-1.88, sighting rats (1.32, 1.10-1.58, and the presence of chickens (1.26, 1.05-1.51. Furthermore, low income and black race (1.25, 1.03-1.50 were independent risk factors. An increase of US$1 per day in per capita household income was associated with an 11% (95% CI 5%-18% decrease in infection risk.Deficiencies in the sanitation infrastructure where slum inhabitants reside were found to be environmental sources of Leptospira transmission. Even after controlling for environmental factors, differences in socioeconomic status contributed to the risk of Leptospira infection, indicating that effective prevention of leptospirosis may need to address the social factors that produce unequal health outcomes among

Land security and the challenges of realizing the human right to water and sanitation in the slums of Mumbai, India.

Science.gov (United States)

Murthy, Sharmila L

2012-12-15

Addressing the human right to water and sanitation in the slums of Mumbai, India requires disentangling the provision of basic services from a more complicated set of questions around land security and land ownership. Millions of slum-dwellers in Mumbai lack adequate access to safe drinking water and sanitation, which places them at risk for waterborne diseases. Many slums are located in hazardous areas such as flood plains, increasing their susceptibility to climate change-related weather patterns. Access to water and sanitation in slums generally hinges on whether a dwelling was created prior to January 1, 1995, because those constructed created prior to that date have greater land security. Although the so-called "1995 cut-off rule" looms large in Mumbai slum policy, a closer reading of the relevant laws and regulations suggests that access to water and sanitation could be expanded to slums created after January 1, 1995. State and municipal governments already have the authority to expand access to water services; they just need to exercise their discretion. However, slums located on central government land are in a more difficult position. Central government agencies in Mumbai have often refused to allow the state and municipal governments to rehabilitate or improve access to services for slums located on their land. As a result, an argument could be made that by interfering with the efforts of sub-national actors to extend water and sanitation to services to slum-dwellers, the central government of India is violating its obligations to respect the human right to water and sanitation under international and national jurisprudence.

Vegetation in Bangalore’s Slums: Boosting Livelihoods, Well-Being and Social Capital

Directory of Open Access Journals (Sweden)

Divya Gopal

2014-04-01

Full Text Available Urban greenery provides ecosystem services that play an important role in the challenging context of urban deprivation and poverty. This study assesses the social importance of vegetation through empirical assessment of 44 urban slums in the rapidly developing southern city of Bangalore, India. Vegetation played a major role in supporting nutrition by its role in food consumption, and in promoting health through the planting of species with medicinal use. Trees in slums also formed nodes for social activities including conversing and playing, domestic activities such as cooking and washing dishes, and livelihood activities such as the manufacture of broomsticks and tyre repair. Innovative methods of gardening were widely adopted, with kitchen gardens found planted in plastic bags, paint cans, old kitchen utensils and buckets, indicating the importance given to planting in environments with limited finances. Short and narrow trunked trees with medium-sized canopies and high economic value, such as Pongamia, were preferred. A greater focus on greening in slums is needed, and can provide an invaluable, inexpensive and sustainable approach to improve lives in these congested, deprived environments.

Community perception regarding rabies prevention and stray dog control in urban slums in India.

The lack of community awareness about rabies control is a major issue that thwarts efforts to prevent human deaths caused by rabies. The objectives of this study were (1) to assess community knowledge and attitudes about rabies, rabies prevention and stray dog control in an urban slum community and (2) to determine the factors that influence rabies awareness in urban slums. Using a systematic random sampling strategy, 185 participants were selected from 8 urban slums. The data were collected by direct interview using a pre-tested, structured questionnaire. In the study population, 74.1% of the participants had heard about rabies, and 54.1% knew that rabies is a fatal disease. Only 33.5% of the interviewees felt that people in the community had a role to play in controlling the stray dog population. Gender, age and educational status were significantly associated with rabies awareness. Our study indicates that there are gaps in the knowledge and attitudes of individuals living in urban slums regarding rabies prevention and control. Efforts to promote awareness should be targeted at men, older people and uneducated individuals. Copyright © 2012 King Saud Bin Abdulaziz University for Health Sciences. Published by Elsevier Ltd.

2013-01-01

This study aimed to (i) examine the contextual influences of urban slum residency on infant mortality and child stunting over and above individual and household characteristics and (ii) identify factors that might modify any adverse effects. We obtained data from Demographic and Health Surveys conducted in 45 countries between 2000 and 2009. The respondents were women (15-49 years) and their children (0-59 months). Results showed that living in a slum neighborhood was associated with infant mortality (OR = 1.34, 95% CI = 1.15-1.57) irrespective of individual and household characteristics and this risk was attenuated among children born to women who had received antenatal care from a health professional (OR = 0.79, 95% CI = 0.63-0.99). Results also indicated that increasing child age exacerbated the risk for stunting associated with slum residency (OR = 1.19, 95% CI = 1.16-1.23). The findings suggest that improving material circumstances in urban slums at the neighborhood level as well as increasing antenatal care coverage among women living in these neighborhoods could help reduce infant mortality and stunted child growth. The cumulative impact of long-term exposure to slum neighborhoods on child stunting should be corroborated by future studies.

Objective: To assess the extent of use of adequately iodized salt in the urban slums of Cuttack. Materials and Methods: Using a stratified random multi-stage cluster sampling design, a cross-sectional study involving 336 households and 33 retail shops selected randomly from 11 slums of Cuttack was conducted in 2005. A predesigned pretested schedule was used to obtain relevant information and salt iodine was estimated qualitatively by using a spot testing kit and quantitatively using the iodometric titration method. Statistical Analysis: Proportion, Chi-square test. Results: Only 60.1% of the households in urban slums of Cuttack were using adequately iodized salt i.e., the iodine level in the salt was ≥15 ppm. Iodine deficiency was significantly marked in sample salts collected from katcha houses as compared with salts collected from pucca houses. Households with low financial status were using noniodized/inadequately-iodized salt. Both crystalline and refined salts were sold at all retail shops. Crystalline salts collected from all retailers had an iodine content < 15 ppm and refined salts collected from one retailer had iodine content < 15 ppm. About 48.5% of salt samples collected from retail shops were adequately iodized. Conclusion: In the urban slums of Cuttack, retailers were selling crystalline salts, which were inadequately iodized- this would be a setback in the progress towards eliminating IDD.

Almost, one third of the world's urban population resides in slums and the number would double by 2030. Slums denotes collection of people from various communities having a meagre income and living in unhygienic conditions thus making themselves most vulnerable for outbreaks of communicable diseases. India contributes substantially to the global disease burden and under-five mortality rates i.e. 20% attributable to vaccine preventable diseases. Immunization plays a crucial role in combating high childhood mortality rates attributable to vaccine preventable diseases across the globe. This systematic review, provides insights on immunization status in slums, identifies various factors influencing it thus, exploring opportunities that may be available to improve vaccination coverage under the National Immunization Program. Taking into account the above aspects, a review of literature was undertaken in various databases that included studies published between 2006 and 2017. In India, ~33% of the urban population lives in slums with suboptimal vaccination coverage ranging from 14% to upto 90%. Few of the important causes for low coverage included socioeconomic factors such as poor community participation, lack of awareness, frequent migration, and loss of daily income. Hence, mere presence of vaccines in the National Immunization Program doesn't do the job, there is a definite unmet need to emphasize upon the importance of immunization among slums dwellers and take necessary steps. For instance, delivering immunization services at the doorstep (e.g. pulse polio program), community-based education, text messaging as reminders and incentivized immunization services are some of the opportunities that can be explored and implemented to improve immunization status in the slums. Thus, in addition to inclusion of more and more vaccines in the National Immunization Program, there is a definite need to focus on people living in high risk areas in order to improve coverage and

To evaluate the effect of a housing transition on sleep quality and quality of life in slum dwellers, participating in a slum housing upgrading program. Observational before-and-after study with a convergent-parallel mixed method design. Five slums located in the metropolitan area of Buenos Aires, Argentina. A total of 150 slum dwellers benefited by a housing program of the nonprofit organization TECHO (spanish word for "roof"). Participants moved from their very low-quality house to a basic prefabricated 18 m(2) modular house provided by TECHO. The Pittsburgh Sleep Quality Index (PSQI) and World Health Organization Quality of Life brief scale (WHOQOL-BREF) were administered before and after housing upgrading. Data about housing conditions, income, education, sleeping conditions, and cardiovascular risk were also collected. Semistructured interviews were used to expand and nuance quantitative data obtained from a poorly educated sample. Results showed that sleep quality significantly increased after the housing program (z = -6.57, P urban settlements could help to define what kind of low-cost intervention may improve sleep quality, quality of life, and reduce existent sleep disparity.

Full Text Available Abstract Background MANOSHI, an integrated community-based package of essential Maternal, Neonatal and Child Health (MNCH services is being implemented by BRAC in the urban slums of Bangladesh since 2007. The objective of the formative research done during the inception phase was to understand the context and existing resources available in the slums, to reduce uncertainty about anticipated effects, and develop and refine the intervention components. Methods Data were collected during Jan-Sept 2007 in one of the earliest sites of programme intervention in the Dhaka metropolitan area. A conceptual framework guided data collection at different stages. Besides exploring slum characteristics, studies were done to map existing MNCH service providing facilities and providers, explore existing MNCH-related practices, and make an inventory of community networks/groups with a stake in MNCH service provision. Also, initial perception and expectations regarding the community delivery centres launched by the programme was explored. Transect walk, observation, pile sorting, informal and focus group discussions, in-depth interviews, case studies, network analysis and small quantitative surveys were done to collect data. Results Findings reveal that though there are various MNCH services and providers available in the slums, their capacity to provide rational and quality services is questionable. Community has superficial knowledge of MNCH care and services, but this is inadequate to facilitate the optimal survival of mothers and neonates. Due to economic hardships, the slum community mainly relies on cheap informal sector for health care. Cultural beliefs and practices also reinforce this behaviour including home delivery without skilled assistance. Men and women differed in their perception of pregnancy and delivery: men were more concerned with expenses while women expressed fear of the whole process, including delivering at hospitals. People expected 'one

In 2014, over half (54%) of the world's population lived in urban areas and this proportion will increase to 66% by 2050. This urbanizing trend has been accompanied by an increasing number of people living in urban poor communities and slums. Lower immunization coverage is found in poorer urban dwellers in many contexts. This study aims to identify factors associated with immunization coverage in poor urban areas and slums, and to identify interventions to improve coverage. We conducted a systematic review, searching Medline, Embase, Global Health, CINAHL, Web of Science and The Cochrane Database with broad search terms for studies published between 2000 and 2016. Of 4872 unique articles, 327 abstracts were screened, leading to 63 included studies: 44 considering factors and 20 evaluating interventions (one in both categories) in 16 low or middle-income countries. A wide range of socio-economic characteristics were associated with coverage in different contexts. Recent rural-urban migration had a universally negative effect. Parents commonly reported lack of awareness of immunization importance and difficulty accessing services as reasons for under-immunization of their children. Physical distance to clinics and aspects of service quality also impacted uptake. We found evidence of effectiveness for interventions involving multiple components, especially if they have been designed with community involvement. Outreach programmes were effective where physical distance was identified as a barrier. Some evidence was found for the effective use of SMS (text) messaging services, community-based education programmes and financial incentives, which warrant further evaluation. No interventions were identified that provided services to migrants from rural areas. Different factors affect immunization coverage in different urban poor and slum contexts. Immunization services should be designed in collaboration with slum-dwelling communities, considering the local context

Debate on the burden of musculoskeletal (MSK) conditions in lower and middle income countries is intensifying; yet, little knowledge so far exists on patterns and impacts of such conditions among general or older adult populations in sub-Saharan Africa (SSA). The objectives of this study are to examine the prevalence, potential predictors, and sequelae of MSK among older adults residing in two low resource informal urban settlements or "slums" in Nairobi Kenya. Data on older adults aged 60 years and over from two unrelated cross-sectional surveys on the older slum populations are used: a 2006/7 survey on the social, health, and overall well-being of older people (sample N = 831), and a 2016 survey on realities and impacts of long-term care and social protection for older adults (sample n = 1026). Uni and multivariate regressions on the 2006/7 data are employed to examine relationships of back pain and symptoms of arthritis with sex, age, wealth, unemployment, diagnoses of hypertension, and diabetes; and with indicators of subjective well-being and functional ability. Descriptive frequencies and chi-squared tests of association are used on 2016 data to identify the overall prevalence and locations of activity limiting MSK pain, and sex differences in these. Prevalence of past month back pain and past 2 week symptoms of arthritis was 44% and 42.6%, respectively. Respective prevalence of past month activity limiting back pain and joint pain was 13.9% and 22.7%. A total of 42.6% of slum residents with a current health problem report MSK as the most severe problem. In multivariate regressions, female sex, unemployment, and diagnosis of hypertension are predictive of back pain and symptoms of arthritis. Both conditions are associated with raised odds of having lower quality of life, poorer life satisfaction, and depressive symptoms, and with mobility impairments and self-care difficulties. MSK conditions are salient, and a likely key cause of impaired subjective well

A focus on bacterial contamination has limited many studies of water service delivery in slums, with diarrheal illness being the presumed outcome of interest. We conducted a mixed methods study in a slum of 12,000 people in Mumbai, India to measure deficiencies in a broader array of water service delivery indicators and their adverse life impacts on the slum's residents. Six focus group discussions and 40 individual qualitative interviews were conducted using purposeful sampling. Quantitative data on water indicators-quantity, access, price, reliability, and equity-were collected via a structured survey of 521 households selected using population-based random sampling. In addition to negatively affecting health, the qualitative findings reveal that water service delivery failures have a constellation of other adverse life impacts-on household economy, employment, education, quality of life, social cohesion, and people's sense of political inclusion. In a multivariate logistic regression analysis, price of water is the factor most strongly associated with use of inadequate water quantity (≤20 liters per capita per day). Water service delivery failures and their adverse impacts vary based on whether households fetch water or have informal water vendors deliver it to their homes. Deficiencies in water service delivery are associated with many non-health-related adverse impacts on slum households. Failure to evaluate non-health outcomes may underestimate the deprivation resulting from inadequate water service delivery. Based on these findings, we outline a multidimensional definition of household "water poverty" that encourages policymakers and researchers to look beyond evaluation of water quality and health. Use of multidimensional water metrics by governments, slum communities, and researchers may help to ensure that water supplies are designed to advance a broad array of health, economic, and social outcomes for the urban poor.

Full Text Available Abstract Background The deprived physical environments present in slums are well-known to have adverse health effects on their residents. However, little is known about the health effects of the social environments in slums. Moreover, neighbourhood quantitative spatial analyses of the mental health status of slum residents are still rare. The aim of this paper is to study self-rated mental health data in several slums of Dhaka, Bangladesh, by accounting for neighbourhood social and physical associations using spatial statistics. We hypothesised that mental health would show a significant spatial pattern in different population groups, and that the spatial patterns would relate to spatially-correlated health-determining factors (HDF. Methods We applied a spatial epidemiological approach, including non-spatial ANOVA/ANCOVA, as well as global and local univariate and bivariate Moran's I statistics. The WHO-5 Well-being Index was used as a measure of self-rated mental health. Results We found that poor mental health (WHO-5 scores Conclusions Spatial patterns of mental health were detected and could be partly explained by spatially correlated HDF. We thereby showed that the socio-physical neighbourhood was significantly associated with health status, i.e., mental health at one location was spatially dependent on the mental health and HDF prevalent at neighbouring locations. Furthermore, the spatial patterns point to severe health disparities both within and between the slums. In addition to examining health outcomes, the methodology used here is also applicable to residuals of regression models, such as helping to avoid violating the assumption of data independence that underlies many statistical approaches. We assume that similar spatial structures can be found in other studies focussing on neighbourhood effects on health, and therefore argue for a more widespread incorporation of spatial statistics in epidemiological studies.

Shekhar, S.

2014-11-01

In India, a number of schemes and programmes have been launched from time to time in order to promote integrated city development and to enable the slum dwellers to gain access to the basic services. Despite the use of geospatial technologies in planning, the local, state and central governments have only been partially successful in dealing with these problems. The study on existing policies and programmes also proved that when the government is the sole provider or mediator, GIS can become a tool of coercion rather than participatory decision-making. It has also been observed that local level administrators who have adopted Geospatial technology for local planning continue to base decision-making on existing political processes. In this juncture, geospatial decision support system (GSDSS) can provide a framework for integrating database management systems with analytical models, graphical display, tabular reporting capabilities and the expert knowledge of decision makers. This assists decision-makers to generate and evaluate alternative solutions to spatial problems. During this process, decision-makers undertake a process of decision research - producing a large number of possible decision alternatives and provide opportunities to involve the community in decision making. The objective is to help decision makers and planners to find solutions through a quantitative spatial evaluation and verification process. The study investigates the options for slum development in a formal framework of RAY (Rajiv Awas Yojana), an ambitious program of Indian Government for slum development. The software modules for realizing the GSDSS were developed using the ArcGIS and Community -VIZ software for Gulbarga city.

Full Text Available Introduction: Not many studies have been conducted regarding contraceptive practices in the slums of Lucknow. This study will be helpful in the assessing the current scenario of prevalence of contraceptive use and various bio-social characteristics that can affect the contraceptive use by the women residing in urban slums of Lucknow. Objectives: To assess the knowledge of contraceptives and its practices among married women in urban slums of Lucknow district. Methodology: This was a descriptive cross-sectional study. Based on thirty cluster sampling technique, thirty urban slums were selected. Total 600 married women of reproductive age group (15-49 years were interviewed in the period of one year from August 2010 to August 2011. Data was collected through preformed and pretested schedule and analysis was done using chi squared test and multiple logistic regression through SPSS 17.0 software. Results: It was found that 99.2 percent married women had the knowledge of contraceptives but its use was only 46.7 percent. Most commonly used contraceptive was condom. Among women who had ever used contraceptives, about 56.3 percent women were current users. Fear of side effects/ health concern was the main reason for discontinuing contraceptive use. Conclusions: Though knowledge of contraceptives among women residing in urban slums of Lucknow was good but contraceptive use was far lagging behind.

The Norway rat (Rattus norvegicus) is the principal reservoir for leptospirosis in many urban settings. Few studies have identified markers for rat infestation in slum environments while none have evaluated the association between household rat infestation and Leptospira infection in humans or the use of infestation markers as a predictive model to stratify risk for leptospirosis. We enrolled a cohort of 2,003 urban slum residents from Salvador, Brazil in 2004, and followed the cohort during four annual serosurveys to identify serologic evidence for Leptospira infection. In 2007, we performed rodent infestation and environmental surveys of 80 case households, in which resided at least one individual with Leptospira infection, and 109 control households. In the case-control study, signs of rodent infestation were identified in 78% and 42% of the households, respectively. Regression modeling identified the presence of R. norvegicus feces (OR, 4.95; 95% CI, 2.13-11.47), rodent burrows (2.80; 1.06-7.36), access to water (2.79; 1.28-6.09), and un-plastered walls (2.71; 1.21-6.04) as independent risk factors associated with Leptospira infection in a household. We developed a predictive model for infection, based on assigning scores to each of the rodent infestation risk factors. Receiver operating characteristic curve analysis found that the prediction score produced a good/excellent fit based on an area under the curve of 0.78 (0.71-0.84). Our study found that a high proportion of slum households were infested with R. norvegicus and that rat infestation was significantly associated with the risk of Leptospira infection, indicating that high level transmission occurs among slum households. We developed an easily applicable prediction score based on rat infestation markers, which identified households with highest infection risk. The use of the prediction score in community-based screening may therefore be an effective risk stratification strategy for targeting control

The aim of this study was to establish reference values for mucociliary clearance and mucociliary clearance reserve capacity as determined by β 2 -adrenergic agonist-induced increase in mucociliary clearance. We studied 62 healthy females (n=33) and males (n=29). Their ages ranged evenly between 18 and 84 years. Fifty-three of the subjects were life-long non-smokers, while nine were ex-smokers. Multiple linear regression analyses showed that mucociliary clearance was significantly faster when the radioaerosol was deposited in the central airways than when it was deposited in the peripheral airways, and faster in life-long non-smokers than in ex-smokers. There was no influence of age, and no convincing association with sex. The variation was less within than between subjects. Mean mucociliary clearance reserve capacity was 21.3% (SD: 10.0%, P 2 agonist-induced increase in lung mucociliary clearance was significantly larger (P<0.05) than the stimulation which has previously been reported in patients with asthma, bronchiectasis or cystic fibrosis. The signal-to-noise ratio of the mucociliary clearance reserve capacity in relation to measurement of baseline mucociliary clearance indicates that measurement of mucociliary clearance reserve capacity may be a more efficient means of distinguishing between ''normal'' and ''abnormal'' mucociliary clearance than single measurement of baseline mucociliary clearance.

Slum areas are heavily populated urban informal settlements characterized by substandard housing and illegal land usage (squatting). Surakarta is one of many Indonesian cities that are still entangled by this problem. One of the slum concentrations in Surakarta is the slum settlement (kampong) alongside Kali Pepe riverbank. Within these slum settlements, people survive in substandard housing by effectively using the limited space. This research aims to discover the typologies of the alternative use of space. This research takes a case study approach in a few kampongs alongside Kali Pepe riverbank, based on the types and sizes of small houses within this area, considering the number of occupants and the space required. The data for this research is categorized as primary data which was collected through a series of site observations and focus group discussions. The data will be analysed, compared, and classified to find out the typology of the alternative solutions of space requirements. This research uses mixed-method analysis to define how Kali Pepe's slum residents alternatively use the spaces within their kampongs. Based on the typologies found through multiple analyses, this research concludes that the use of space in substandard housing cannot be bound by limited spaces. Furthermore, the main strategy to solve the problem of limited space is by using alternative spaces.

Full Text Available Introduction: Diarrhea is a leading cause of mortality in children in developing countries and the condition is worse in slums. In order to provide effective preventive and management strategies, it is important to identify factors associated with the disease. This study was carried out to investigate the risk factors of diarrhea in  children under five years of age in urban slums. Methods: Parents of all children under five years from the urban slums of Tansen municipality, Palpa, Nepal were interviewed using a standardized pretested questionnaire and proforma. Parental variables, environmental factors, and presence of diarrhea in those children in past three months were collected by trained enumerators and the data were analyzed with statistical software SPSS-10. Results: A total of 450 under five years children were enrolled in the study. There were 216 (48% male and 234 (52% female children with F:M ratio of 1.08:1. Occurrence of diarrhea was lower if the children were breast-fed for more than six months, well-nourished, used fountain water for drinking, or used boiled or treated water. Similarly, diarrhea prevalence was lower if father had a regular job, daily income in the family was more than one US dollar, there was a toilet in the house, practice of hand washing was followed before feeding or preparing food, or there was no child suffering from diarrhea in the neighborhood. Conclusion: There are a few variables that are significantly related to diarrhea in children under five years of age. In order to decrease the diarrheal episodes in children in the slums of the developing countries, priority could be given in the improvement of those variables.

Isotope determinations of renal clearance equivalent with physiological clearance measurements

Junges, R.

1983-01-01

The concept of renal clearance in nuclear medicine describes the tubular secretion and glomerular filtration of a substance being removed from the blood plasma. The concept of clearance as used physiologically is rather wider and includes consideration of the outflow of the substances remained back in the kidneys. The present paper discusses clearance measurements as seen from a thermodynamic point of view, in which isotope clearances become equivalent with the physiological concept of clearance. In addition, it is possible to quantify each single step of the excretory function of each kidney separately. (orig.) [de

Despite one-third of the urban population in Bangladesh living in urban slums and at increased risk of non-communicable diseases (NCDs), little is known about the NCD risk profile of this at-risk population. The aim of the study was to identify the prevalence of the NCD risk factors and the association of NCD risk factors with socio-demographic factors among the adults of urban slums in Dhaka, Bangladesh. A cross-sectional study was conducted among adult slum dwellers (aged 25 and above) residing in three purposively selected urban slums of Dhaka for at least six months preceding the survey. The risk factors assessed were- currently smoking, fruit and vegetable intake, physical activity, hypertension and body mass index (BMI). Information on self-reported diabetes was also taken. A total of 507 participants (252 females; 49.7%) were interviewed and their physical measures were taken using the WHO NCD STEPS instrument. The overall prevalence of NCD risk factors was: 36.0% (95% CI: 31.82-40.41) for smoking; 95.60% (95% CI: 93.60-97.40) for insufficient fruit and vegetable intake; 15.30% (95% CI:12.12-18.71) for low physical activity;13.70% (95% CI: 10.71-16.92) for hypertension; 22.70% (95% CI: 19.31-26.02) for overweight or obesity; and 5.00% (95%: 3.20-7.00) for self-reported diabetes. In the logistic regression model, the clustering of three or more NCD risk factors was positively associated with younger age groups (p = 0.02), no formal education (p slum adults. These findings are important to support the formulation and implementation of NCD-related polices and plan of actions that recognize urban slum populations in Bangladesh as a priority sub-population.

Full Text Available Introduction: Safe drinking water is scarce in Kolkata. Inadequate knowledge and poor practices of storing and cleaning drinking water can cause severe effects on the health of the population. There is a need to understand the current trend of attitudes and practices of individuals living in urban slums to reduce water-borne diseases and mortality. This limited convenience sample study attempted to explore and identify areas for further study regarding the barriers of clean water access in urban slums of Kolkata, India. Methods: This pilot cross-sectional study was conducted in Kolkata, India during July 2014. Five urban slums were selected based on proximity and cooperation from the community. A sample of 50 women was taken, representing the five slums, with a sample of 10 women taken from each slum. Results: The majority (80% of the participants said they regularly have enough water available to meet the needs of their household. Fifty-two percent of subjects received their water for drinking from a tap, hand pump, or time pump. Thirty percent had water pumped into their homes, and 18% purchased their water from a water truck. Fourteen percent said they did not treat their water because it was too time consuming, 40% said it was too much work, and 34% said it was not needed. Ninety percent said they felt it was important to clean their water, almost half (48% thought their water was not clean, but only 42% used some method to clean their water. Many subjects (68% stated they knew how to clean their water, but 66% were unaware that visible dirt is not an indicator of illness-causing bacteria in water. Conclusions: More focus should be directed towards improving awareness and knowledge and changing attitudes, motivation, and perceived susceptibility to disease from water within slum communities in Kolkata, India.

For children, maintenance of personal hygiene helps to improve the quality of life and longevity. This is of particular importance in a slum community with compromised living situation. This study was undertaken to find out the knowledge and practice of personal hygiene among the primary school children living in a slum area, to identify any misconception among them regarding the maintenance of personal hygiene, to find out their morbidity pattern, and also to elicit the relationship between practice of personal hygiene among the children and the literacy status of their mother. A cross-sectional observational study was conducted among 104 primary school children of a primary school situated in the slum area of Chetla, Kolkata, India with the help of a predesigned, pre-tested and structured questionnaire. Data were analyzed statistically by simple proportions and tests of significance. It was found that the female students were more knowledgeable than the male students regarding the maintenance of personal hygiene. There was a wide gap between practice and knowledge of personal hygiene among the primary school children living in the slum area. Even, misconceptions do exist on certain indicators of personal hygiene among the students. Statistically significant association was observed between practices of personal hygiene among the primary school children and the literacy status of their mother. Future of a society depends considerably on the health of its children. The parents and the school teachers, as constructive shapers of children's health behaviors, should play a responsible role in early education of children on personal hygiene.

Observations are reported relating to the endogenous creatinine clearance, the Tc-99m-EDTA-complex clearance and the creatinine clearance estimated via a selected mathematical formula, with special regard to the problems of renal insufficiency and the nephrotic syndrome. The activity applied was in the range of 3.7-7.4 MBq. It was observed that measurement of the isotope clearance can also be applied to determine the endogeneous creatinine clearance in otherwise less suitable patients. A reliable result is obtained even if the renal function is restricted, but the accuracy of the method may be reduced in nephrotic syndrome cases. (author) 24 refs

Slums are densely populated, neglected parts of cities where housing and living conditions are exceptionally poor. In situ slum upgrading, at its basic level, involves improving the physical environment of the existing area, such as improving and installing basic infrastructure like water, sanitation, solid waste collection, electricity, storm water drainage, access roads and footpaths, and street lighting, as well as home improvements and securing land tenure. To explore the effects of slum upgrading strategies involving physical environment and infrastructure interventions on the health, quality of life and socio-economic wellbeing of urban slum dwellers in low and middle income countries (LMIC). Where reported, data were collected on the perspectives of slum dwellers regarding their needs, preferences for and satisfaction with interventions received. We searched for published and unpublished studies in 28 bibliographic databases including multidisciplinary (for example Scopus) and specialist databases covering health, social science, urban planning, environment and LMIC topics. Snowballing techniques included searching websites, journal handsearching, contacting authors and reference list checking. Searches were not restricted by language or publication date. We included studies examining the impact of slum upgrading strategies involving physical environment or infrastructure improvements (with or without additional co-interventions) on the health, quality of life and socio-economic wellbeing of LMIC urban slum dwellers. Randomised controlled trials (RCTs), controlled before and after studies (CBAs) and interrupted time series (ITS) were eligible for the main analysis. Controlled studies with only post-intervention data (CPI) and uncontrolled before and after (UBA) studies were included in a separate narrative to examine consistency of results and to supplement evidence gaps in the main analysis. Two authors independently extracted data and assessed risk of bias

The presence of viruses in a slum environment where sanitation is poor is a major concern. However, little is known of their occurrence and genomic copy concentration in the slum environment. The main objective of this study was to determine the genomic copy concentrations of human adenoviruses F and G, Rotavirus (RV), Hepatitis A virus (HAV), Hepatitis E virus (HEV) and human adenovirus species A,C,D,E, and F (HAdV-ACDEF) in Bwaise III, a typical slum in Kampala, Uganda. Forty-one samples from surface water, grey water and ground water were collected from 30 sampling locations. The virus particles were recovered by glass wool filtration with elution using beef extract. DNA and RNA viruses were detected by the real time quantitative polymerase chain reaction (qPCR) and the reverse transcription-qPCR (RT-qPCR), respectively. HAdV-F and G were detected in 70.7% of the samples with concentrations up to 2.65 × 10(1) genomic copies per mL (gc mL(-1)). RV and HAV were detected in 60.9% and 17.1% of the samples, respectively. The maximum concentration of RV was 1.87 × 10(2)gc mL(-1). In addition, 78% of the samples tested positive for the HAdV-ACDEF, but all samples tested negative for HEV. These new data are essential for quantitative microbial risk assessment, and for understanding the effects of environmental pollution in slums.

The aim of this study was to examine the associations of food store choice with food consumption among urban slum women. A cross-sectional survey was carried out among 188 urban slum women (19-50 years old) in Jakarta, Indonesia. A semiquantitative food frequency questionnaire was used to assess food consumption. Associations between food consumption and food store choice were tested by linear regression. This study found that frequencies of buying food from small shops (warung), street food vendors, and modern food stores were significantly associated with consumption of snacks, mixed dishes, and fruit respectively. In addition, buying food from traditional markets and small cafes (warung makan) was not significantly associated with particular types of food consumption. As modern food stores are rarely utilized by these women, small shops (warung) and street food vendors are likely to be important channels to improve slum dwellers' diet. © 2016 APJPH.

To evaluate predictive validity of cognitive dysfunction of the Saint Louis University mental status (SLUMS) exam or mini-mental state exam (MMSE) for institutionalization and mortality after 7.5-years. Longitudinal study. Geriatric Research, Education and Clinical Center Veterans Affairs Hospital St. Louis, MO. Patients (N=705) were screened for cognitive dysfunction in 2003 using the SLUMS exam and MMSE, and mortality and institutionalization up to 7.5-years later were evaluated as outcome measures. The associations between outcome measures and MMSE and SLUMS exam total scores, and cognitive status were examined using Kaplan-Meier curves and Cox proportional-hazards regression. Five hundred thirty-three charts were reviewed, 176/533(33%) patients had died and 31/526 (6%) were institutionalized during 7.5-year follow-up period. All subjects were male with a mean age of 75 years and most had high school education or greater (71%). MMSE dementia, SLUMS dementia (ps<.001) and MCI (p<.05) groups had significantly lower survival rates than normal cognition group in the Kaplan-Meier curves. Scores classified as dementia on SLUMS (HR=2.4, 95% CI 1.6-3.7; p <.001) or MMSE (HR=2.3, 95% CI 1.5-3.6; p <.001) both predicted mortality and, also, institutionalization (SLUMS: HR=3.5, 95% CI 1.3-9.1; p <.01; MMSE: HR=3.8, 95% CI 1.6-9.0; p <.001) after adjustment for covariates. Unadjusted SLUMS exam MCI predicted morality (HR=1.5, 95% CI 1.1-2.2; p <.019) but not institutionalization. The SLUMS exam and MMSE both predict mortality and institutionalization for male patients screened as positive for dementia.

On-site sanitation provisions in urban slums rarely prioritise grey water management, yet it forms the largest fraction of wastewater. This study was carried out to characterise grey water and quantify its pollutant loads in Bwaise III (Uganda) and to provide data for grey water management in urban slums of developing countries. Samples were collected for analysis from ten representative households as well as from four tertiary drains and the main drainage channel for 7 months in two dry seasons. Grey water production was found to comprise 85 % of the domestic water consumption. The chemical oxygen demand concentration in the grey water generated by laundry, in the kitchen and in the bathroom was 9,225 ± 1,200 mg L-1, 71,250 ± 1,011 mg L-1 and 4,675 ± 750 mg L-1, while the BOD5 (biochemical oxygen demand) to COD ratio was 0.24 ± 0.05, 0.33 ± 0.08 and 0.31 ± 0.07, respectively. The maximum concentration of Escherichia coli and total coliforms was 2.05 9 107 cfu (100 mL)-1 and 1.75 9 108 cfu (100 mL)-1, respectively, in grey water from the bathroom, while that of Salmonella spp. was 7.32 9 106 cfu (100 mL)-1 from laundry. Analysis of variance (ANOVA) showed a significant difference in the concentration of COD, total suspended solids, total organic carbon, dissolved organic carbon, total phosphorus, sodium adsorption ratio, oil and grease, and Salmonella spp. in grey water from laundry, bathroom and kitchen (p/0.05). The high loads of COD ([500 kg day-1), total suspended solids ([200 kg day-1), nutrients (8.3 kg TKN day-1 and 1.4 kg total phosphorus day-1) and microorganisms (106 to 109 cfu c-1 day-1) originating from grey water in Bwaise III show that grey water poses a threat to the environment and a risk to human health in urban slums. Therefore, there is a need to prioritise grey water treatment in urban slums of developing countries to achieve adequate sanitation.

Nutritional status differs between infants and young children living in slum and non-slum conditions-infants and young children living in City Corporation slums are likely to have worse nutritional status compared to those from non-slums. Furthermore, families in slums tend to engage female labor in cash-earning activities as a survival strategy; hence, a higher percentage of mothers stay at work. However, little is known about feeding practices for infants and young children in families with working mothers in slums. This study aims to understand the factors that determine feeding practices for infants and young children living in families with working mothers in Dhaka slums. This study adopted a qualitative approach. Sixteen In-depth Interviews, five Key Informant Interviews, and Focused Group Discussions were conducted with family members, community leaders, and program staff. Method triangulation and thematic analyses were conducted. Feeding practices for infants and young children in families with working mothers are broadly determined by mothers' occupation, basis civic facilities, and limited family buying capacity. Although mothers have good nutritional knowledge, they negotiate between work and feeding their infants and young children. Household composition, access to cooking facilities, and poverty level were also found to be significant determining factors. The results suggest a trade-off between mothers' work and childcare. The absence of alternative care support in homes and/or work places along with societal factors outweighs full benefits of project interventions. Improving alternative childcare support could reduce the burden of feeding practice experienced by working mothers and may improve nutritional outcomes.

There are recent efforts made to eliminate inequalities in the utilisation of basic health care services. More emphasis is given for improvement of health in developing countries including maternal and child health. However, disparities for the fast-growing population of urban poor are masked by the urban averages. The aim of this paper is to report on the findings of antenatal care adequacy among slum residents in Addis Ababa, Ethiopia. This was a quantitative and cross-sectional community based study design which employed a stratified two-stage cluster sampling technique to determine the sample. Data was collected using structured questionnaire administered to 870 women aged 15-49 years. Weighted 'backward selection' logistic regression models were employed to identify predictors of adequacy of antenatal care. Majority of slum residents did not have adequate antenatal care services with only 50.3, 20.2 and 11.0 % of the slum resident women initiated antenatal care early, received adequate antenatal care service contents and had overall adequate antenatal care services respectively. Educational status and place of ANC visits were important determinant factors for adequacy of ANC in the study area. Women with secondary and above educational status were 2.7 times more likely to receive overall adequate care compared to those with no formal education. Similarly, clients of private healthcare facilities were 2.2 times respectively more likely to receive overall adequate antenatal care compared to those clients of public healthcare facilities. In order to improve ANC adequacy in the study area, the policy-making, planning, and implementation processes should address the poor adequacy of ANC among the disadvantaged groups in particular and the slum residents in general.

Comparison of [ 51 Cr]EDTA plasma clearance corrected for extrarenal elimination with 24 h endogenous creatinine clearance in patients with advanced renal failure showed that the corrected [ 51 Cr]EDTA clearance was lower than creatinine clearance, and thus might be a better approximation to the glomerular filtration rate in uraemic patients. The corrections cannot be used on [ 51 Cr]EDTA clearance values below the mean extrarenal clearance, averaging 3.7 ml/min. (Auth.)

Undernutrition among children is a major public health concern worldwide, more prevalent in Asia and Africa. It manifests itself in various forms such as wasting or stunting or underweight and retards physical and mental development, increases susceptibility to infection, and reduces educational attainment and productivity. The present study was undertaken to assess the level of wasting, stunting, and underweight and determine its associates among slum children of 3-9 years of age, residing in Bhubaneswar city, India. After obtaining informed consent, a total of 249 children from 249 households were studied and their parents/guardians were interviewed to collect all relevant information. 23.3%, 57.4%, and 45.4% of children were found to have wasting, stunting, and underweight, respectively. Variables like birth order of child, period of initiation of breastfeeding and mother's education were found to be strong predictors of wasting, whereas toilet facility in household and practice of drinking water storage were significantly associated with stunting among slum children as revealed in multiple regression analysis. Thus, a multipronged approach is needed such as giving priority to improve education for slum community especially for women, creating awareness regarding benefits of early initiation of breastfeeding, small family size, and proper storage of drinking water, and providing toilet facility in slum households which could improve the nutritional status of slum children.

Full Text Available Background: Rapid rural-urban migration of people to cities is a reality around the globe that has increased city slum dwellers. Sodom and Gomorrah is a city slum located in the heart of Accra, Ghana. Like other slums, it lacks basic amenities necessary for dwellers’ quality of life. This study describes residents’ access to health and factors associated with the use of healthcarefacilities. Methods: Questionnaires were administered in systematically selected shacks across the entire slum. Data on demographic characteristics, existent health facilities and number of users, health-insured residents and knowledge of common diseases were collected. Results: Majority of the residents were from the northern parts of Ghana, relative to the south and a few of them come from other parts of West Africa. Seventy-one percent of residents had never visited a health facility in the last 5 years. When necessary, they access health care from drug stores (61.1% or hospitals (33.1%. Residents’ age, educational status, income, health knowledge and membership of National Health Insurance Scheme were significantly (p < 0.05 associated with the use of healthcare facilities. Younger residents and those without National Health Insurance Scheme membership, formal education, no knowledge of common illnesses and regular income were significantly less likely to use a healthcare facility. For most residents, neither distance (73.2% nor transportation to health facilities was a problem (74.1%. Conclusion: Conditions of profound environmental hazards, overcrowding, poor-quality housing and lack of health care in Sodom and Gomorrah pose grave threats to the health of the inhabitants. Multisectoral interventions and resource mobilisation championed by the Ministry of Local Government and Rural Development are needed to alter the trend. Keywords: Slum dwellers, health, access, Sodom and Gomorra, Ghana

Full Text Available Background: Bangladesh is a small South Asian country which became independent in 1971 after a bloody war. Rapid urbanisation in Bangladesh (26% of the 147.1 million inhabitants live in urban areas is fuelling a growth in urban poverty, particularly in the urban slums where the quality of life is extremely poor. The average population density in slums was reported in 2005 as 831 persons per acre or 205,415 people per square kilometre.1 Early commencement of antenatal care by pregnant women as well as regular visits has the potential to affect maternal and foetal outcome. Objective: To assess the status of ANC service used by the pregnant mothers and their socio-demographic characteristics. Materials and Methods: A community-based cross-sectional study was conducted at Moghbazar slum area in Dhaka district of Bangladesh, during January to June 2014. A total of 161 slum dwellers were enrolled in the study. Information regarding education, occupation, monthly family income, antenatal care was gathered using a pretested structured questionnnare and data were analysed. Results: The majority respondents had knowledge about antenatal care and of them 89 (55.2% completed ≥3 visits. Forty five (47.8% pregnant women received ANC from government hospitals. Nearly 72% mothers received ANC service from doctors and 16.9% received from family welfare visitors (FWV. Half of mothers were satisfied with the overall care provided to them. About 86.2% mothers said that they had to wait for more than two hours for check-ups. More than 50% received information about exercise and 36% were reassured about discussing fear and anxiety about pregnancy. Conclusion: This study reveals that antenatal care provided was not up to the mark of standard care and measures should be taken to improve it.

Poor solid waste management is among the major challenges facing urban slums in developing countries including Uganda. Understanding community concerns and willingness towards involvement in solid waste management improvement initiatives is critical for informing interventions in slums. We used a cross-sectional study to collect quantitative data from 435 residents in two urban slums in central Uganda. A semistructured questionnaire was used which assessed waste collection practices, separation and disposal methods, concerns regarding solid wastes, and willingness to participate in waste separation and composting. Data was analysed using STATA 12. Food remains (38%) and plastics (37%) formed the biggest proportion of wastes generated in households. Most households (35.9%) disposed of general wastes by open dumping while 27% disposed of plastics by burning. Only 8.8% of households conducted composting while 55% carried out separation for some decomposable wastes. Separation was carried out for only banana peelings and leftover foods for feeding animals. Respondents expressed high willingness to separate (76.6%) and compost (54.9%) solid wastes. Practices in waste disposal and separation were poor despite high willingness to participate in initiatives to improve waste management, highlighting a need for authorities to engage residents of slums to improve their practices.

To quantitatively assess disease burden due to tuberculosis between populations residing in and outside of urban informal settlements in Rio de Janeiro, Brazil, we compared disability-adjusted life years (DALYs), or "DALY-gap." Using the 2010 Brazilian census definition of informal settlements as aglomerados subnormais (AGSN), we allocated tuberculosis (TB) DALYs to AGSN vs non-AGSN census tracts based on geocoded addresses of TB cases reported to the Brazilian Information System for Notifiable Diseases in 2005 and 2010. DALYs were calculated based on the 2010 Global Burden of Disease methodology. DALY-gap was calculated as the difference between age-adjusted DALYs/100,000 population between AGSN and non-AGSN. Total TB DALY in Rio in 2010 was 16,731 (266 DALYs/100,000). DALYs were higher in AGSN census tracts (306 vs 236 DALYs/100,000), yielding a DALY-gap of 70 DALYs/100,000. Attributable DALY fraction for living in an AGSN was 25.4%. DALY-gap was highest for males 40-59 years of age (501 DALYs/100,000) and in census tracts with <60% electricity (12,327 DALYs/100,000). DALY-gap comparison revealed spatial and quantitative differences in TB burden between slum vs non-slum census tracts that were not apparent using traditional measures of incidence and mortality. This metric could be applied to compare TB burden or burden for other diseases in mega-cities with large informal settlements for more targeted resource allocation and evaluation of intervention programs.

UNMET NEED OF SEX EDUCATION AMONG ADOLESCENTS IN URBAN SLUM AREA: AN INTERVENTIONAL STUDY

Directory of Open Access Journals (Sweden)

Tamboli Kshitij S, Avachat Subhada S, Tamboli Suchit S

2015-07-01

Full Text Available Context: Adolescents comprise one-fifth of India’s total population. There is widespread ignorance associated with unprotected sex, contraceptives, among young people. As majority adolescents in slum areas have illiterate and ignorant family backgrounds; they are misguided by the myths. Hence providing sex education for them is the need of the hour. Aims: 1 To assess the knowledge and awareness of adolescents in an urban slum area regarding some aspects of reproductive health. 2 To assess the need of sex education among them. 3 To study the impact of sex education on their knowledge Material and Methods: An interventional study was done on 132 adolescents of urban slum area, selected by simple random sampling. Informed consent was obtained from the participants. Data was collected with the help of structured questionnaire prepared by literature search. Response of adolescents was recorded through questionnaires. A sensitization workshop was organized as intervention. The same questionnaire was given to them and the effect of intervention was assessed. Statistical analysis of data was done using percentage, proportion and appropriate tests of significance. Result and Conclusions: Only 31.06% adolescents had discussed the topic of reproductive health with some or other person and out of them friends were the major sources (39.2% of information. Only 38.63% knew the hazards of teenage pregnancy which significantly rose to 89.4% after intervention workshop. The study concludes that the slum adolescents profoundly lack adequate knowledge of sexuality related matters. Even before intervention workshop, unmet need of reproductive health education was 59.1% and 93.93% was the felt need in the post test.

In 2008, the global urban population surpassed the rural population and by 2050 more than 6 billion will be living in urban centres. A growing body of research has reported on poor health outcomes among the urban poor but not much is known about HIV prevalence among this group. A survey of nearly 3000 men and women was conducted in two Nairobi slums in Kenya between 2006 and 2007, where respondents were tested for HIV status. In addition, data from the 2008/2009 Kenya Demographic and Health Survey were used to compare HIV prevalence between slum residents and those living in other urban and rural areas. The results showed strong intra-urban differences. HIV was 12% among slum residents compared with 5% and 6% among non-slum urban and rural residents, respectively. Generally, men had lower HIV prevalence than women although in the slums the gap was narrower. Among women, sexual experience before the age of 15 compared with after 19 years was associated with 62% higher odds of being HIV positive. There was ethnic variation in patterns of HIV infection although the effect depended on the current place of residence. Copyright © 2012 Elsevier Ltd. All rights reserved.

Undernutrition among children is a major public health concern worldwide, more prevalent in Asia and Africa. It manifests itself in various forms such as wasting or stunting or underweight and retards physical and mental development, increases susceptibility to infection, and reduces educational attainment and productivity. The present study was undertaken to assess the level of wasting, stunting, and underweight and determine its associates among slum children of 3–9 years of age, residing in Bhubaneswar city, India. After obtaining informed consent, a total of 249 children from 249 households were studied and their parents/guardians were interviewed to collect all relevant information. 23.3%, 57.4%, and 45.4% of children were found to have wasting, stunting, and underweight, respectively. Variables like birth order of child, period of initiation of breastfeeding and mother's education were found to be strong predictors of wasting, whereas toilet facility in household and practice of drinking water storage were significantly associated with stunting among slum children as revealed in multiple regression analysis. Thus, a multipronged approach is needed such as giving priority to improve education for slum community especially for women, creating awareness regarding benefits of early initiation of breastfeeding, small family size, and proper storage of drinking water, and providing toilet facility in slum households which could improve the nutritional status of slum children.

Full Text Available OBJECTIVE : To assess the awareness and attitude towards AIDS and PLHA in slum dwellers of Chennai, an Indian metropolis by KAP (Knowledge, Attitude, Practice study. METHODS : A cross sectional study was conducted in a representative sample of 650 subjects (400 females and 250 females, aged 15-45 years, by means of a questionnaire in the local dialect Tamil. RESULTS : The overall literacy rate was 64%, with males being 70% and females being 60% literate. 20% of males and 11% of females do not know about a disease called AIDS. Only 67% of males and 55% of females are aware of the sexual mode of transmission. 34% of males and 50% females opine that AIDS is also a hereditary disease. Also 45% of males and 62% of females feel that AIDS also spreads by air, fomites, or mosquito-bite. Only 30% of males and 22% females know about the possible symptoms of AIDS. 30% of males and 45% of females never ask for a new syringe if not provided, as they are totally unaware of its significance. 43% of males and 78% of females do not know about the risk of a barber′s blade. 56% of males and 71% of females feel that AIDS can be treated at least by a traditional medicine. Lastly, 48% of males and 60% females prefer outcasting an AIDS patient from the slum. CONCLUSIONS : AIDS awareness in the slum dwellers of Chennai is very poor. Corresponding awareness in suburbs and rural areas will be much worse. Conventional IEC methods targeting general population via mass media are not reaching the slum dwellers, even in a metropolitan city. A specially designed targeted intervention is needed.

Full Text Available With 2.8 billion biomass users globally, household air pollution remains a public health threat in many low- and middle-income countries. However, little evidence on pollution levels and health effects exists in low-income settings, especially slums. This study assesses the levels and sources of household air pollution in the urban slums of Nairobi. This cross-sectional study was embedded in a prospective cohort of pregnant women living in two slum areas—Korogocho and Viwandani—in Nairobi. Data on fuel and stove types and ventilation use come from 1058 households, while air quality data based on the particulate matters (PM2.5 level were collected in a sub-sample of 72 households using the DustTrak™ II Model 8532 monitor. We measured PM2.5 levels mainly during daytime and using sources of indoor air pollutions. The majority of the households used kerosene (69.7% as a cooking fuel. In households where air quality was monitored, the mean PM2.5 levels were high and varied widely, especially during the evenings (124.6 µg/m3 SD: 372.7 in Korogocho and 82.2 µg/m3 SD: 249.9 in Viwandani, and in households using charcoal (126.5 µg/m3 SD: 434.7 in Korogocho and 75.7 µg/m3 SD: 323.0 in Viwandani. Overall, the mean PM2.5 levels measured within homes at both sites (Korogocho = 108.9 µg/m3 SD: 371.2; Viwandani = 59.3 µg/m3 SD: 234.1 were high. Residents of the two slums are exposed to high levels of PM2.5 in their homes. We recommend interventions, especially those focusing on clean cookstoves and lighting fuels to mitigate indoor levels of fine particles.

Socioenvironmental conditions and intestinal parasitic infections in Brazilian urban slums: a cross-sectional study

Full Text Available ABSTRACT Intestinal parasitic infections (IPIs are neglected diseases with limited data regarding prevalence in Brazil and many other countries. In increasingly urban societies, investigating the profile and socioenvironmental determinants of IPIs in the general population of slum dwellers is necessary for establishing appropriate public policies catered to these environments. This study assessed the socioenvironmental conditions and prevalence of IPIs in slums of Rio de Janeiro, RJ State, Brazil. Methods A cross-sectional study covering an agglomeration of urban slums was conducted between 2015 and 2016 using participants observation, a socioeconomic survey, and the spontaneous sedimentation method with three slides per sample to analyze fresh stool specimens ( n =595 searching for intestinal parasites. Results Endolimax nana ( n =95, 16.0% and Entamoeba coli ( n =65, 10.9% were the most frequently identified agents, followed by Giardia intestinalis ( n =24, 4.0% and Ascaris lumbricoides ( n =11, 1.8%. Coinfections caused by E. nana and E. histolytica/dispar and by Entamoeba coli/A. lumbricoides were significant. The use of piped water as drinking water, the presence of A. lumbricoides , and contamination with coliform bacteria and Escherichia coli were more common in major area (MA 1. Children (0-19 years had a greater chance of living in poverty (OR 3.36; 95% CI: 2.50- 4.52; p <0.001 which was pervasive. The predominance of protozoa parasites suggests that a one-size-fits-all approach focusing on preventive chemotherapy for soil-transmitted helminths is not appropriate for all communities in developing countries. It is important that both residents and health professionals consider the socioenvironmental conditions of urban slums when assessing intestinal parasitic infections for disease control and health promotion initiatives.

Almost 40% of Delhi's population lives in slums and is vulnerable to tobacco use. It is therefore important to assess their opinion and ensure compliance to antismoking legislation. The present study was undertaken to assess the awareness of the general public residing in slums in Delhi regarding the smoke-free initiative of 2009, 3 years after intensive implementation. It was a cross-sectional study conducted among participants selected by cluster sampling from the slums in six districts of Delhi using a pretested semistructured questionnaire. A total of 708 slum dwellers were interviewed. Out of the total, only 16.1% (n = 114) of the participants had heard of The Cigarettes and Other Tobacco Products (Prohibition of Advertisement and Regulation of Trade and Commerce, Production, Supply and Distribution) Act, 2003 (COTPA), though, they were aware about some of the provisions of the COTPA. Majority (n = 529; 74.7%) perceived the smoke-free zones as the places where smoking forms of tobacco are banned. Regarding the awareness about the places designated as smoke-free zones, 82.1% (n = 581) of the respondents named educational institutions. About 61% of the people interviewed reported to have seen people smoking at public places on the day of interview while only 21.5% reported to have seen any one getting punished for smoking. Awareness about COTPA was low. The study respondents perceived that no action was being taken against persons acting in violation of the law. Thus, there is a need for stricter implementation of COTPA and increased spreading of awareness among the general public. While awareness about antismoking legislation among general population (particularly slums) has been studied world over, this has not been the case in India. The study depicts opinion of one of the susceptible populations regarding tobacco control legislation, which has hitherto not been studied in the Indian context. This study has an important implication as it highlights the need

Full Text Available Objective: To study the effect of various maternal factors on the prevalence of underweight and stunting among 1-5-year-old children in urban slum population. Design: Cross-sectional study. Materials and Methods: The study was carried out in three urban slums of Tripuri Town, Patiala. All 1-5-year children living in these slums were included, whose mother′s demographic profile, weight and height were recorded. Results: Out of 482 children who participated in the study, 185 (38.38% had low weight for age whereas 222 (46.06% had low height for age. Both kinds of malnutrition were common in females than in males. Prevalence of malnutrition was more where mother′s age was less than 20 years. Children of educated mothers were better nourished as compared to illiterate ones. Conclusion: Maternal factors significantly affect a child′s nutritional status, thus encouraging the improvement in the social status of women so as to have healthy children and thereby a healthy future.

How Insecurity impacts on school attendance and school drop out among urban slum children in Nairobi

Directory of Open Access Journals (Sweden)

Chimaraoke Izugbara

2008-06-01

Full Text Available This paper discusses how perceptions of personal security can impact on school enrolment and attendance. It mainly focuses on threats of physical harm, crime, and community and domestic violence. These security fears can include insecurity that children suffer from as they go to school, maybe through the use of unsafe routes; insecurity that children feel at school; and the insecurity they suffer from in their homes. Although poverty can be a source and/or an indicator of insecurity, this paper does not focus solely on poverty as it is well covered elsewhere in the literature. The paper relies on qualitative data col- lected in Korogocho and Viwandani slum areas in Nairobi, Kenya between October and November 2004. The paper analyses data from individual interviews and focus group interviews and focuses on the narrative of slum dwellers on how insecurity impacts on educational attainment. The conclusion in this paper is that insecure neighbourhoods may have a negative impact on schooling. As a result policies that address insecurity in slum neighbourhoods can also improve school attendance and performance.

Ninety-five percent of burn deaths occur in low- and middle-income countries (LMICs); however, longitudinal household-level studies have not been done in urban slum settings, where overcrowding and unsafe cook stoves may increase likelihood of injury. Using a prospective, population-based disease surveillance system in the urban slum of Kibera in Kenya, we examined the incidence of household-level burns of all severities from 2006-2011. Of approximately 28,500 enrolled individuals (6000 households), we identified 3072 burns. The overall incidence was 27.9/1000 person-years-of-observation. Children slums rapidly increases in many African countries, characterizing and addressing the rising burden of burns is likely to become a public health priority.

Of voyeuristic safari tours and responsible tourism with educational value: Observing moral communication in slum and township tourism in Cape Town and Mumbai

Directory of Open Access Journals (Sweden)

Burgold. Julia

2013-11-01

Full Text Available Sightseeing in the poorest quarters of southern hemisphere cities has been observed occurring in Cape Town, Rio de Janeiro, Mumbai and many other cities. The increasing global interest in touring poor urban environments is accompanied by a strong morally charged debate; so far, this debate has not been critically addressed. This article avoids asking if slum tourism is good or bad, but instead seeks a second-order observation, i.e. to investigate under what conditions the social praxis of slum tourism is considered as good or bad, by processing information on esteem or disesteem among tourists and tour providers. Special attention is given to any relation between morality and place, and the thesis posited is that the moral charging of slum tourism is dependent on the presence of specific preconceived notions of slums and poverty. This shall be clarified by means of references to two empirical case studies carried out in (1 Cape Town in 2007 and 2008 and (2 Mumbai in 2009.

Development of the clearance level verification evaluation system. 2. Construction of the clearance data management system

Clearance is defined as the removal of radioactive materials or radioactive objects within authorized practices from any further regulatory control by the regulatory body. In Japan, clearance level and a procedure for its verification has been introduced under the Laws and Regulations, and solid clearance wastes inspected by the national authority can be handled and recycled as normal wastes. The most prevalent type of wastes have generated from the dismantling of nuclear facilities, so the Japan Atomic Energy Agency (JAEA) has been developing the Clearance Level Verification Evaluation System (CLEVES) as a convenient tool. The Clearance Data Management System (CDMS), which is a part of CLEVES, has been developed to support measurement, evaluation, making and recording documents with clearance level verification. In addition, validation of the evaluation result of the CDMS was carried out by inputting the data of actual clearance activities in the JAEA. Clearance level verification is easily applied by using the CDMS for the clearance activities. (author)

Full Text Available INTRODUCTION: Understanding of family planning scenario among different societies and communities, which by and large reside in urban slum areas, might prove useful in increasing family planning acceptance by them and decreasing population growth. Unmet need is a valuable indicator for assessing the achievements of national family planning programs. OBJECTIVES: The present study was undertaken with the objectives to estimate unmet need for family planning among the married women of reproductive age group (15 - 49 years in urban slums of Lucknow and to determine the various factors that influence the unmet need. METHODS: A community based cross - sectional study was conducted in slums of Lucknow City from February 2014 to September 2014. A total 452 married women in reproductive age group were interviewed through house to house survey with the help of a pre - designed, pre - tested and semi - structured questionnaire. RESULTS: The total unmet need for family planning was 69.0%. Multivariate logistic regression revealed socioeconomic status upper lower and below (OR 2.7; 95% CI 1.5 - 5.1; p = 0.00; duration of marriage less than 1 year (OR 1.8; 95% CI 1.1 - 2.9; p = 0.01; less number of live issues (OR 1.6; 95% CI 1.1 - 2.5; p = 0.00; working status of women (OR 1.9; 95% CI 1.1 - 2.9; p = 0.03; social class i.e. OBC and SC/ST (OR 2.3; 95% CI 1.1 - 4.6; p = 0.02 were found to be independent predictors of unmet need of family planning. CONCLUSION: The present study revealed that unmet need for family planning was quite high among women belonging to social class i.e. OBC and SC/ST, with low socioeconomic status, duration of marriage less than one year less number of live issues and working status of the women.

Rapid rural-urban migration of people to cities is a reality around the globe that has increased city slum dwellers. Sodom and Gomorrah is a city slum located in the heart of Accra, Ghana. Like other slums, it lacks basic amenities necessary for dwellers' quality of life. This study describes residents' access to health and factors associated with the use of healthcarefacilities. Questionnaires were administered in systematically selected shacks across the entire slum. Data on demographic characteristics, existent health facilities and number of users, health-insured residents and knowledge of common diseases were collected. Majority of the residents were from the northern parts of Ghana, relative to the south and a few of them come from other parts of West Africa. Seventy-one percent of residents had never visited a health facility in the last 5 years. When necessary, they access health care from drug stores (61.1%) or hospitals (33.1%). Residents' age, educational status, income, health knowledge and membership of National Health Insurance Scheme were significantly (p < 0.05) associated with the use of healthcare facilities. Younger residents and those without National Health Insurance Scheme membership, formal education, no knowledge of common illnesses and regular income were significantly less likely to use a healthcare facility. For most residents, neither distance (73.2%) nor transportation to health facilities was a problem (74.1%). Conditions of profound environmental hazards, overcrowding, poor-quality housing and lack of health care in Sodom and Gomorrah pose grave threats to the health of the inhabitants. Multisectoral interventions and resource mobilisation championed by the Ministry of Local Government and Rural Development are needed to alter the trend.

2012-01-01

Full Text Available Background : The increasing proportion of elderly persons is contributing to an increase in the prevalence of diabetes. The residents of urban slums are more vulnerable due to poverty and lack of access to health care. Objective: To estimate the prevalence of diabetes in elderly persons in an urban slum and to assess their awareness, treatment and control of this condition. Materials and Methods : All persons aged 60 years and above, residing in an urban slum of Delhi, were included in this cross-sectional community- based study. Data were collected on sociodemographic variables. The participants′ awareness and treatment of diabetes was recorded. Their fasting blood sugar was estimated using an automated glucometer. Diabetes was diagnosed if fasting blood glucose was ≥126 mg/dL, or if the participant was taking treatment for diabetes. Impaired fasting blood glucose was diagnosed if fasting blood glucose was 110-125 mg/dL. Results: Among the 474 participants studied, the prevalence of diabetes was estimated to be 18.8% (95% CI 15.3-21.5. It decreased with increasing age, and was higher among women. The prevalence of impaired fasting blood glucose was 19.8% (95% CI 16.3-23.7. It was higher among women. One-third of the diabetic participants were aware of their condition; two-thirds of these were on treatment and three-fourths of those on treatment had controlled fasting blood sugar level. The awareness, treatment and control were better among women. Conclusions : Diabetes is common among elderly persons in urban slums. Its magnitude and low awareness warrant effective public health interventions for their treatment and control.

Full Text Available Effectiveness of community-based leprosy control operations spanning almost a decade in two locations, a small self settled leprosy colony (I of about 800 subjects as well as a large slum (II with a population of about 20,000 in the metropolitan city of Bombay are compared. New case detection through survey in location I and voluntary reporting in location II during the period 1982-86 is taken as an index of the impact of the intervention, which consisted of field based administration of multi-drug therapy. Though the leprosy colony concentrates an abnormal reservoir of infectious cases in a small population, it was relatively easier to achieve success in reducing the transmission rate through field-based chemotherapy programme. The same degree of success however, could not be achieved in a normal slum. Health care delivery system in relation to leprosy eradication at the grass-root levels has to be planned giving maximum importance to cost-effective methods of identification of multi-bacillary leprosy patients and monitoring their movements carefully during the treatment phase.

Children living in slums are at high risk of being malnourished. There are no published reviews on existing interventions promoting better nutrition for children living in slums and the risk factors for children's malnutrition. Improved understanding of the risk factors for malnutrition in slums communities and the impact of interventions on children's health can provide guidance to practitioners and decision-makers. The present review is designed to provide this information. The search included 30 electronic bibliographic databases and relevant eligible studies published up to December 2013. The search located 1512 citations. Full text relevance screening was conducted on 226 studies and on abstracts for 16 studies. The final 58 unique studies included 22 on interventions and 38 on risk. All of the interventions were nutrition-specific, with nutritional intervention being the most dominant type. Seventy-three per cent of the interventions were assessed effective. The findings stressed the gaps in knowledge in terms of quality assessment and programmatic recommendations to identify children who are the most at risk of malnutrition to appropriately target interventions. Finally, the review helped to inform a systematic review (Cochrane Systematic review protocol 2015) that will examine the impact of interventions on outcome measures.

Human rights and reproductive health: political realities and pragmatic choices for married adolescent women living in urban slums, Bangladesh.

Rashid, Sabina Faiz

2011-12-16

In Bangladesh, particularly in urban slums, married adolescent women's human rights to life, health, and reproductive and sexual health remain adversely affected because of the structural inequalities and political economic, social and cultural conditions which shape how rights are understood, negotiated and lived. The focus of the research and methods was anthropological. An initial survey of 153 married adolescent women was carried out and from this group, 50 in-depth interviews were conducted with selected participants and, from the in-depth interviews, a further eight case studies of women and their families were selected for in-depth repeated interviews and case histories. This paper speaks of the unanticipated complexities when writing on reproductive rights for poor adolescent women living in the slums, where the discourses on 'universal human rights' are often removed from the reality of adolescent women's everyday lives. Married adolescent women and their families remain extremely vulnerable in the unpredictable, crime-prone and insecure urban slum landscape because of their age, gender and poverty. Adolescent women's understanding of their rights such as the decision to marry early, have children, terminate pregnancies and engage in risky sexual behaviour, are different from the widely accepted discourse on rights globally, which assumes a particular kind of individual thinking and discourse on rights and a certain autonomy women have over their bodies and their lives. This does not necessarily exist in urban slum populations. The lived experiences and decisions made pertaining to sexual and reproductive health and 'rights' exercised by married adolescent women, their families and slum communities, allow us to reflect on the disconnect between the international legal human rights frameworks as applied to sexual and reproductive health rights, and how these are played out on the ground. These notions are far more complex in environments where married

A million dollar exit from the anarchic slum-world: Slumdog Millionaire's hollow idioms of social justice.

2010-01-01

This article contests the characterisation of the popular and acclaimed film, Slumdog Millionaire, as a realistic portrayal of India's urban poverty that will ultimately serve as a tool of advocacy for India's urban poor. It argues that the film's reductive view of slum-spaces will more probably reinforce negative attitudes towards slum-dwellers, lending credibility to the sorts of policies that have historically dispossessed them of power and dignity. By drawing attention to the film's celebration of characters and spaces that symbolise Western culture and Northern trajectories of 'development', the article also critically engages with some of the issues raised by the film's enormous success.

Background & objectives: Domestic violence is identified as a public heath problem. It is associated with adverse maternal health. This study examined the prevalence and determinants of domestic violence among women in urban slums of Mumbai, India. Methods: A community based cross-sectional household survey was carried out among eligible women for the study during September 2012 to January 2013. A total of 1137 currently married women aged 18-39 yr with unmet need for family planning and having at least one child were selected using cluster systematic random sampling from two urban slums. Information on socio-demographic, reproductive and domestic violence was collected through face-to-face interview using a pretested structured questionnaire after obtaining informed written consent. Bivariate and multivariate analyses were carried out to find the socio-demographic factors associated with ever experienced domestic violence among women. Results: The prevalence of women ever experiencing domestic violence in the community was 21.2 per cent. Women whose husband consumed alcohol [RR: 2.17, (95% CI: 1.58-2.98)] were significantly at an increased risk of ever experiencing domestic violence than their counterparts. Risk of domestic violence was twice [RR: 2.00, (95% CI: 1.35-2.96)] for women who justified wife beating than women who did not justify wife beating. Interpretation & conclusions: The findings showed that domestic violence was prevalent in urban slums. Factors like early marriage, working status, justified wife beating and husbands use of alcohol were significantly associated with domestic violence. PMID:26205021

Women whose husband consumed alcohol [RR: 2.17, (95% CI: 1.58-2.98] were significantly at an increased risk of ever experiencing domestic violence than their counterparts. Risk of domestic violence was twice [RR: 2.00, (95% CI: 1.35-2.96] for women who justified wife beating than women who did not justify wife beating. Interpretation & conclusions: The findings showed that domestic violence was prevalent in urban slums. Factors like early marriage, working status, justified wife beating and husbands use of alcohol were significantly associated with domestic violence.

Full Text Available Background: The largest proportion of women with an unmet need for contraception is found among those in their first year after childbirth; concentrating efforts to reduce unmet need among these women could have additionally bigger impact on increasing contraceptive use than concentrating on any other group. Aims & Objectives: To know the knowledge & practices of post – partum contraception among mothers in urban slums. Material & Methods: Cross sectional study conducted in urban slums for duration of six months. Study population included mothers in extended post – partum period residing in urban slums. Mothers were interviewed using pre – tested, semi – structured questionnaire. Data was analyzed using SPSS v 22.0 and, chi square test and logistic regression analysis was employed. P value of <0.05 was considered statistically significant. Results: Majority of the mothers in our study were in the age group of 20-24 years (46%. Mean age was 21.6 ± 3.1years. Majority of the mothers (56% were Hindus. Mean age of marriage observed was 18.2±2.1years. In the present study, majority (76% had knowledge of post – partum contraceptive methods, but only 17% of the mothers were using contraception. Unmet need for post – partum contraception was found among 49% of mothers. Conclusions: Inspite of being aware, the practice of family planning was very low among post-partum mothers. The study highlights the impact of socio cultural factors like religion, caste, number of living children, duration of marriage and ANC service utilization on post – partum contraception usage among mothers.

Background Knowledge of tuberculosis has been shown to influence health seeking behaviour; and urban slum dwellers are at a higher risk of acquiring tuberculosis than the general population. The study aim was to assess knowledge of tuberculosis and identify the associated socio-demographic determinants, in order to inform tailored interventions for advocacy, communication and social mobilisation in three urban-slum communities of Uganda. Methods A cross-sectional survey of 1361 adults between April and October 2011. Data was analyzed by descriptive statistics. Adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) of potential determinants of tuberculosis (TB) knowledge were estimated by multivariable ordinal logistic regression using Stata 11.2 software. Results We found low knowledge of TB cause (26.7%); symptoms (46.8%), transmission (54.3%), prevention (34%) and free treatment (35%). Knowledge about TB treatment (69.4) and cure (85.1) was relatively high. Independent determinants of poor knowledge of TB in the multivariable analysis included (aOR, 95% CI) lack of formal education (0.56; 0.38 – 0.83, P = 0.004), unemployment (0.67; 0.49 – 0.90, P = 0.010) and never testing for HIV (0.69; 0.51 – 0.92, P slum dwellers in Uganda. Tuberculosis control programmes in similar settings should consider innovative strategies for TB education, advocacy, communication and social mobilisation to reach the youth, unemployed and less-educated; as well as those who have never tested for HIV.

To determine the magnitude of microbial risks from waterborne viruses and bacteria in Bwaise III in Kampala (Uganda), a typical slum in Sub-Saharan Africa. A quantitative microbial risk assessment (QMRA) was carried out to determine the magnitude of microbial risks from waterborne pathogens through various exposure pathways in Bwaise III in Kampala (Uganda). This was based on the concentration of Escherichia coli O157:H7, Salmonella spp., rotavirus (RV) and human adenoviruses F and G (HAdV) in spring water, tap water, surface water, grey water and contaminated soil samples. The total disease burden was 680 disability-adjusted life years (DALYs) per 1000 persons per year. The highest disease burden contribution was caused by exposure to surface water open drainage channels (39%) followed by exposure to grey water in tertiary drains (24%), storage containers (22%), unprotected springs (8%), contaminated soil (7%) and tap water (0.02%). The highest percentage of the mean estimated infections was caused by E. coli O157:H7 (41%) followed by HAdV (32%), RV (20%) and Salmonella spp. (7%). In addition, the highest infection risk was 1 caused by HAdV in surface water at the slum outlet, while the lowest infection risk was 2.71 × 10(-6) caused by E. coli O157:H7 in tap water. The results show that the slum environment is polluted, and the disease burden from each of the exposure routes in Bwaise III slum, with the exception of tap water, was much higher than the WHO reference level of tolerable risk of 1 × 10(-6) DALYs per person per year. The findings of this study provide guidance to governments, local authorities and nongovernment organizations in making decisions on measures to reduce infection risk and the disease burden by 10(2) to 10(5) depending on the source of exposure to achieve the desired health impacts. The infection risk may be reduced by sustainable management of human excreta and grey water, coupled with risk communication during hygiene awareness

Recent activities on clearance in IAEA and clearance automatic laser inspection system (CLALIS)

International Nuclear Information System (INIS)

Hattori, Takatoshi; Sasaki, Michiya

2005-01-01

Exemption levels for bulk amounts of materials have been described in RS-G-1.7 published as a safety guide in IAEA on August 2004. In Japan, the Nuclear Safety Commission adopted the RS-G-1.7 values as Japanese clearance levels after the careful review of dose assessment results. After completing revises of regulatory laws in relation to clearance level, solid wastes from decommissioning and operating nuclear power plants will be targets of clearance inspection. In CRIEPI, Clearance Automatic Laser Inspection System (CLALIS) has been developed, which can give high reliability and objectivity to the measurement data. The CLALIS is a new monitoring system coupling with 3D laser shape measurement, Monte-Carlo calculation and gamma measurement techniques, which can keep a high accuracy in the measurement data using an automatic correction technique for self-shielding effects of metal waste itself and is expected to apply as a practical use in actual clearance inspections.

Full Text Available NTRODUCTION: Aging refers to normal, progressive and irreversible biological changes that occur over an individual’s life span. The advancement of medical science and increased awareness among the people has brought about a sharp decline in mortality and a steady decline in fertility. This has resulted in a worldwide shift in the demographic profile and has led to significant increase in the aged population. About two thirds of all older people are concentrated in the developing world. OBJECTIVES: to study & compare socio - demographic variables of old age people living in Urban & Urban slum areas. MATERIAL & METHODS: all the old age people living in urb a n slum area & rando mly selected one urban area of K arad town were interviewed by using pre structured proforma about socio - demographic variable & compared with each other. OBSERVATIONS: Total 153 from urban & 135 from urban slum were enrolled for the study. Nearly 2/3 rd subjects were above age 65yrs in both areas with more female proportions in slum area than urban area. Significant difference was found with education, occupation & socio - economic status in both areas. CONCLUSION: Ageing is a universal phenomenon, with advanced fertility control, improvement in health and social services life expectancy has increased. Ageing has profound effect on the individual status in the family, the work force, goals and organization of health, social services, policies and practices of the government

2009-01-01

This paper analyzes the Generic Clearance Values established for natural and artificial radionuclides with the objective of evaluating their degree of conservatism in views of adopting them into the regulatory body. Generic clearance values for natural radionuclides have been chosen by experts judgments as the optimum boundary between, on one hand, the ubiquitous unmodified soil concentrations and, on the other hand, activity concentrations in ores, mineral sands, industrial residues and wastes. For artificial radionuclides the clearance levels have been derived from the scenarios postulated in the document 'Safety Reports Series Nr 44' of the IAEA considering quantitative exemption criteria. A set of 8 scenarios were postulated covering external, ingestion and inhalation exposure pathways. For each radionuclide, the generic clearance level was derived as the more restrictive value obtained from the scenarios, that is the lowest ratio between the applicable individual dose and the dose per unit activity concentration (Bq/g). The individual dose was calculated by a formula depending on each scenario and pathway, with different parameters, such as exposure time, dosimetric factors, dilution factor, density of the material, geometric factors, etc. It was concluded that the basis and parameters used for the derivation of the generic clearance levels are quite conservative and therefore its the adoption in Argentina has been recommended. It is expected that their implementation will contribute to optimize the regulatory management system. (author)

Rat-borne leptospirosis is an emerging zoonotic disease in urban slum settlements for which there are no adequate control measures. The challenge in elucidating risk factors and informing approaches for prevention is the complex and heterogeneous environment within slums, which vary at fine spatial scales and influence transmission of the bacterial agent. We performed a prospective study of 2,003 slum residents in the city of Salvador, Brazil during a four-year period (2003-2007) and used a spatiotemporal modelling approach to delineate the dynamics of leptospiral transmission. Household interviews and Geographical Information System surveys were performed annually to evaluate risk exposures and environmental transmission sources. We completed annual serosurveys to ascertain leptospiral infection based on serological evidence. Among the 1,730 (86%) individuals who completed at least one year of follow-up, the infection rate was 35.4 (95% CI, 30.7-40.6) per 1,000 annual follow-up events. Male gender, illiteracy, and age were independently associated with infection risk. Environmental risk factors included rat infestation (OR 1.46, 95% CI, 1.00-2.16), contact with mud (OR 1.57, 95% CI 1.17-2.17) and lower household elevation (OR 0.92 per 10m increase in elevation, 95% CI 0.82-1.04). The spatial distribution of infection risk was highly heterogeneous and varied across small scales. Fixed effects in the spatiotemporal model accounted for the majority of the spatial variation in risk, but there was a significant residual component that was best explained by the spatial random effect. Although infection risk varied between years, the spatial distribution of risk associated with fixed and random effects did not vary temporally. Specific "hot-spots" consistently had higher transmission risk during study years. The risk for leptospiral infection in urban slums is determined in large part by structural features, both social and environmental. Our findings indicate that

Full Text Available Background: Total fertility rate of Uttar Pradesh is 2.7 with annual growth rate of 16.5. Age specific marital fertility rate (ASMFR in Uttar Pradesh is highest in the age group of 20-24 years (383.9 followed by 15-19 years (271.0 age group. Use of contraceptives is also very low in this most productive age group. Among the Young married women in the age group of 15-24 years the contraceptive prevalence rate (CPR is only 27.75% which is quite low than the target CPR of 60%. State level data presents a grim picture of contraceptive use in the slum areas in comparison to non-slum areas. This slum population is the most vulnerable section of our society. Aims & Objectives: i To assess the prevalence of non-use of contraceptives among young married women living in urban slums. ii To understand the reasons for non-use of contraceptives among young married women. iii To explore the factors influencing non-use of contraceptive among young married women. Materials and Methods: A cross sectional study was carried out in the urban slums of Lucknow. Out of the eight Nagar-Nigam zones in Lucknow, one Urban-Primary Health Centre was selected randomly from each zone. From each Urban- Primary Health Centre, 2 slums were selected randomly. In selected slum, all the households were visited until at least 33 young married women (15-24 years were interviewed using a pre-tested questionnaire to obtain the desired sample size of 535. The data was analyzed using SPSS 16.0. Results: Current use of contraceptives was found to be 33.8 % and almost two-thirds (66.2% of the participants were not using any form of contraceptive method. The important reasons for non-use of contraception were embarrassment / hesitancy / shyness regarding family planning, lack of knowledge about the contraceptive method or place of availability of services, opposition to contraceptive use by husband or family members and women’s desire to get pregnant. About one third of the women had no

2016-03-05

Intimate partner violence (IPV) is an urgent public health priority. It is a neglected issue in women's health, especially in urban slums in Nepal and globally. This study was designed to better understand the IPV experienced by young pregnant women in urban slums of the Kathmandu Valley, as well as to identify their coping strategies, care and support seeking behaviours. Womens' views on ways to prevent IPV were also addressed. 20 young pregnant women from 13 urban slums in the Kathmandu valley were recruited purposively for this qualitative study, based on pre-defined criteria. In-depth interviews were conducted and transcribed, with qualitative content analysis used to analyse the transcripts. 14 respondents were survivors of violence in urban slums. Their intimate partner(s) committed most of the violent acts. These young pregnant women were more likely to experience different forms of violence (psychological, physical and sexual) if they refused to have sex, gave birth to a girl, or if their husband had alcohol use disorder. The identification of foetal gender also increased the experience of physical violence at the prenatal stage. Interference from in-laws prevented further escalation of physical abuse. The most common coping strategy adopted to avoid violence among these women was to tolerate and accept the husbands' abuse because of economic dependence. Violence survivors sought informal support from their close family members. Women suggested multiple short and long term actions to reduce intimate partner violence such as female education, economic independence of young women, banning identification of foetal gender during pregnancy and establishing separate institutions within their community to handle violence against young pregnant women. Diversity in the design and implementation of culturally and socially acceptable interventions might be effective in addressing violence against young pregnant women in humanitarian settings such as urban slums. These

Background In Bangladesh, particularly in urban slums, married adolescent women’s human rights to life, health, and reproductive and sexual health remain adversely affected because of the structural inequalities and political economic, social and cultural conditions which shape how rights are understood, negotiated and lived. Methods The focus of the research and methods was anthropological. An initial survey of 153 married adolescent women was carried out and from this group, 50 in-depth interviews were conducted with selected participants and, from the in-depth interviews, a further eight case studies of women and their families were selected for in-depth repeated interviews and case histories. Results This paper speaks of the unanticipated complexities when writing on reproductive rights for poor adolescent women living in the slums, where the discourses on ‘universal human rights’ are often removed from the reality of adolescent women’s everyday lives. Married adolescent women and their families remain extremely vulnerable in the unpredictable, crime-prone and insecure urban slum landscape because of their age, gender and poverty. Adolescent women’s understanding of their rights such as the decision to marry early, have children, terminate pregnancies and engage in risky sexual behaviour, are different from the widely accepted discourse on rights globally, which assumes a particular kind of individual thinking and discourse on rights and a certain autonomy women have over their bodies and their lives. This does not necessarily exist in urban slum populations. Conclusions The lived experiences and decisions made pertaining to sexual and reproductive health and ‘rights’ exercised by married adolescent women, their families and slum communities, allow us to reflect on the disconnect between the international legal human rights frameworks as applied to sexual and reproductive health rights, and how these are played out on the ground. These notions are

AbstractDiarrhea is a leading cause of mortality in children under 5 years of age. We conducted a cross-sectional study of 54 children aged 3 months to 5 years old in Kibera, an urban slum in Nairobi, Kenya, to assess the relationship between caregiver-reported soil ingestion and child diarrhea. Diarrhea was significantly associated with soil ingestion (adjusted odds ratio = 9.9, 95% confidence interval = 2.1-47.5). Soil samples from locations near each household were also collected and analyzed for Escherichia coli and a human-associated Bacteroides fecal marker (HF183). Escherichia coli was detected in 100% of soil samples (mean 5.5 log colony forming units E. coli per gram of dry soil) and the Bacteroides fecal marker HF183 was detected in 93% of soil samples. These findings suggest that soil ingestion may be an important transmission pathway for diarrheal disease in urban slum settings.

Full Text Available Abstract Background India has seen rapid unorganized urbanization in the past few decades. However, the burden of childhood diseases and malnutrition in such populations is difficult to quantify. The morbidity experience of children living in semi-urban slums of a southern Indian city is described. Methods A total of 176 children were recruited pre-weaning from four geographically adjacent, semi-urban slums located in the western outskirts of Vellore, Tamil Nadu for a study on water safety and enteric infections and received either bottled or municipal drinking water based on their area of residence. Children were visited weekly at home and had anthropometry measured monthly until their second birthday. Results A total of 3932 episodes of illness were recorded during the follow-up period, resulting in an incidence of 12.5 illnesses/child-year, with more illness during infancy than in the second year of life. Respiratory, mostly upper respiratory infections, and gastrointestinal illnesses were most common. Approximately one-third of children were stunted at two years of age, and two-thirds had at least one episode of growth failure during the two years of follow up. No differences in morbidity were seen between children who received bottled and municipal water. Conclusions Our study found a high burden of childhood diseases and malnutrition among urban slum dwellers in southern India. Frequent illnesses may adversely impact children’s health and development, besides placing an additional burden on families who need to seek healthcare and find resources to manage illness.

2017-01-01

The mental health of women residing in slum areas is a neglected and important public health concern. The present cross-sectional study was undertaken during 2012-2013 to assess frequently occurring mental disorders and associated factors among married women 15-45 years of age, residing in slum areas of Bhubaneswar, India. A multistage, cluster, random sampling design was applied to select the study areas. The presence of a mental disorder was determined using a validated, self-reported questionnaire, developed by the World Health Organization. Using a predesigned, pretested schedule, relevant data were collected from 362 eligible, willing women respondents. Eighty women (22.1%) had a mental disorder, 56 (70.0%) of whom never consulted a health-care provider. Results of multiple logistic regression indicated that presence of a mental disorder was positively associated with not being satisfied with managing household financial affairs, not having time to attend social obligations, attending religious services less than four times per month, addiction of a family member to alcohol or drugs, and misunderstandings or quarrels in the family. Policy makers should be encouraged to incorporate such determinants in schemes or programs intended to promote the mental health of married slum women.

The clearance system is a legal system to release 'the radioactive waste not requiring treatment as radioactive waste' from the regulatory control. JNES supports NISA on approval and confirmation of clearance measurement and judgment developed by the operator. The objective of this study is to establish technical base of the validation method of the clearance measurement for various objects. In reactor facilities, the bulk measurement technique or the statistical sampling measurement technique may be applied to large scale objects or concrete walls. In this study, the criteria of those techniques were examined. In uranium processing facilities, it is important to confirm surface state of the object in case of detecting alpha rays. The result of the examination about the influence of the surface rust in the uranium clearance measurement by the alpha ray measurement showed that the pollution was distributed in rust layer uniformly. This result will be reflected to the revision of the Ministerial Ordinance on Clearance in 2011FY. To develop a manual for unexpected incidents, the response procedure for an unexpected incident was prepared, including a response system. (author)

Full Text Available Background At present of the limitation of the current case finding strategies and the global urgency to improve tuberculosis (TB case finding, a renewed interest in active case finding (ACF has risen. World Health Organization (WHO calls for research on TB screening among low-income countries because of the limitation of the passive case finding strategies. We aimed to evaluated Active Case Finding strategy for TB among the slums population in North of Iran (Gorgan city and comprise this procedure to Passive Case Finding. Materials and Methods We conducted a house-to-house survey from April 2016 to July 2016 by trained health volunteers for TB in ten urban slums of Gorgan. Individuals with TB symptoms were identified through targeted screening using a standardized questionnaire and investigated further for TB. Descriptive analyses were performed using Stata-12. Results During study period, of 22,741 individuals screened for TB, 112 (0.49% were identified as TB suspects; 95 suspects were evaluated for TB. TB was diagnosed in four individuals, representing 4.2% of those evaluated for TB as suspected cases. The incidence rate of tuberculosis was 17.5 in 100.000 people in slums population of Gorgan. Of the four detected cases, three individuals had pulmonary TB that among them two cases had new smear-positive TB. Conclusion ACF could supplement current strategies to yield additional TB cases, lead to early diagnosis and better treatment.

Emerging changes in reproductive behaviour among married adolescent girls in an urban slum in Dhaka, Bangladesh.

Science.gov (United States)

Rashid, Sabina Faiz

2006-05-01

Structural and social inequalities, a harsh political economy and neglect on the part of the state have made married adolescent girls an extremely vulnerable group in the urban slum environment in Bangladesh. The importance placed on newly married girls' fertility results in high fertility rates and low rates of contraceptive use. Ethnographic fieldwork among married adolescent girls, aged 15-19, was carried out in a Dhaka slum from December 2001-January 2003, including 50 in-depth interviews and eight case studies from among 153 married adolescent girls, and observations and discussions with family and community members. Cultural and social expectations meant that 128 of the girls had borne children before they were emotionally or physically ready. Twenty-seven had terminated their pregnancies, of whom 11 reported they were forced to do so by family members. Poverty, economic conditions, marital insecurity, politics in the household, absence of dowry and rivalry among family, co-wives and in-laws made these young women acquiesce to decisions made by others in order to survive. Young married women's status is changing in urban slum conditions. When their economical productivity takes priority over their reproductive role, the effects on reproductive decision-making within families may be considerable. This paper highlights the vulnerability of young women as they pragmatically make choices within the social and structural constraints in their lives.

To determine whether a glomerular filtration rate (GFR) assay based on serum iohexol clearance can be used to predict carboplatin clearance in cats. 10 cats with tumors. GFR was measured concurrently by use of plasma clearance of technetium Tc 99m-labeled diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) to yield GFR(99mTc-DTPA) and serum clearance of iohexol to yield GFR(Iohexol). A single dose of carboplatin was administered IV as a bolus. Dose was calculated by use of a target value for the area under the plasma platinum concentration-versus-time curve (AUC(Target)) and estimation of platinum clearance (CL(PT)) derived from GFR(99mTc-DTPA) as follows: dose = AUC(Target) x 2.6 x GFR(99mTc-DTPA) x body weight, where AUC(Target) is 2.75 min.mg.mL(-1). Plasma platinum concentrations were measured via atomic absorption spectrophotometry. Values for GFR(99mTc-DTPA) and GFR(Iohexol) were compared by use of least-squares regression and Bland-Altman analysis. Least-squares regression was used to determine whether CL(PT) could be predicted from GFR(99mTc-DTPA) or GFR(Iohexol) (or both). GFR(99mTc-DTPA) and GFR(Iohexol) were strongly correlated (r = 0.90), but GFR(Iohexol) values were significantly larger by a factor of approximately 1.4. Platinum clearance had a significant linear relationship to GFR(99mTc-DTPA) (CL(PT) = 2.5 x GFR(99mTc-DTPA)) and to GFR(Iohexol) (CL(PT) = [1.3 x GFR(Iohexol)] + 1.4). In cats, serum iohexol clearance was an accurate predictor of CL(PT) and can be used to calculate the carboplatin dose as follows: dose = AUC(Target) x ([1.3 x GFR(Iohexol)] + 1.4) x body weight.

Full Text Available Introduction: Cardiovascular disease (CVD is a leading cause of death in sub-Saharan Africa (SSA, with annual deaths expected to increase to 2 million by 2030. Currently, most national health systems in SSA are not adequately prepared for this epidemic. This is especially so in slum settlements where access to formal healthcare and resources is limited. Objective: To develop and introduce a model of cardiovascular prevention in the slums of Nairobi by integrating public health and private sector approaches. Study design: Two non-profit organizations that conduct public health research, Amsterdam Institute for Global Health and Development (AIGHD and African Population and Health Research Center (APHRC, collaborated with private-sector Boston Consulting Group (BCG to develop a service delivery package for CVD prevention in slum settings.

Malnutrition continues to be a critical public health problem in sub-Saharan Africa. For example, in East Africa, 48 % of children under-five are stunted while 36 % are underweight. Poor health and poor nutrition are now more a characteristic of children living in the urban areas than of children in the rural areas. This is because the protective mechanism offered by the urban advantage in the past; that is, the health benefits that historically accrued to residents of cities as compared to residents in rural settings is being eroded due to increasing proportion of urban residents living in slum settings. This study sought to determine effect of mother's education on child nutritional status of children living in slum settings. Data are from a maternal and child health project nested within the Nairobi Urban Health and Demographic Surveillance System (NUHDSS). The study involves 5156 children aged 0-42 months. Data on nutritional status used were collected between October 2009 and January 2010. We used binomial and multiple logistic regression to estimate the effect of education in the univariable and multivariable models respectively. Results show that close to 40 % of children in the study are stunted. Maternal education is a strong predictor of child stunting with some minimal attenuation of the association by other factors at maternal, household and community level. Other factors including at child level: child birth weight and gender; maternal level: marital status, parity, pregnancy intentions, and health seeking behaviour; and household level: social economic status are also independently significantly associated with stunting. Overall, mothers' education persists as a strong predictor of child's nutritional status in urban slum settings, even after controlling for other factors. Given that stunting is a strong predictor of human capital, emphasis on girl-child education may contribute to breaking the poverty cycle in urban poor settings.

Urban slum adolescents and young adults have disproportionately high rates of HIV compared to rural and non-slum urban youth. Yet, few studies have examined youth's perceptions of the economic drivers of HIV. Informed by traditional and behavioral economics, we applied a scarcity theoretical framework to qualitatively examine how poverty influences sexual risk behaviors among adolescents and young adults. Focus group discussions with one hundred twenty youth in Kenyan's urban slums were transcribed, coded, and analyzed using interpretive phenomenology. Results indicated that slum youth made many sexual decisions considered rational from a traditional economics perspective, such as acquiring more sex when resources were available, maximizing wealth through sex, being price-sensitive to costs of condoms or testing services, and taking more risks when protected from adverse sexual consequences. Youth's engagement in sexual risk behaviors was also motivated by scarcity phenomena explained by behavioral economics, such as compensating for sex lost during scarce periods (risk-seeking), valuing economic gains over HIV risks (tunneling, bandwidth tax), and transacting sex as an investment strategy (internal referencing). When scarcity was alleviated, young women additionally described reducing the number of sex partners to account for non-economic preferences (slack). Prevention strategies should address the traditional and behavioral economics of the HIV epidemic.

Inadequate urban sanitation disproportionately impacts the social determinants of women's health in informal settlements or slums. The impacts on women's health include infectious and chronic illnesses, violence, food contamination and malnutrition, economic and educational attainment, and indignity. We used household survey data to report on self-rated health and sociodemographic, housing, and infrastructure conditions in the Mathare informal settlement in Nairobi, Kenya. We combined quantitative survey and mapping data with qualitative focus group information to better understand the relationships between environmental sanitation and the social determinants of women and girls' health in the Mathare slum. We find that an average of eighty-five households in Mathare share one toilet, only 15% of households have access to a private toilet, and the average distance to a public toilet is over 52 meters. Eighty-three percent of households without a private toilet report poor health. Mathare women report violence (68%), respiratory illness/cough (46%), diabetes (33%), and diarrhea (30%) as the most frequent physical burdens. Inadequate, unsafe, and unhygienic sanitation results in multiple and overlapping health, economic, and social impacts that disproportionately impact women and girls living in urban informal settlements.

Public Health Risks in Urban Slums: Findings of the Qualitative 'Healthy Kitchens Healthy Cities' Study in Kathmandu, Nepal.

Full Text Available Communities in urban slums face multiple risks to their health. These are shaped by intermediary and structural determinants. Gaining a clear understanding of these determinants is a prerequisite for developing interventions to reduce the health consequences of urban poverty. With 828 million people living in slum conditions, the need to find ways to reduce risks to health has never been greater. In many low income settings, the kitchen is the epicentre of activities and behaviours which either undermine or enhance health.We used qualitative methods of semi-structured interviews, observation and participatory workshops in two slum areas in Kathmandu, Nepal to gain women's perspectives on the health risks they faced in and around their kitchens. Twenty one women were interviewed and four participatory workshops with a total of 69 women were held. The women took photographs of their kitchens to trigger discussions.The main health conditions identified by the women were respiratory disease, gastrointestinal disease and burn injuries. Women clearly understood intermediary (psychosocial, material and behavioural determinants to these health conditions such as poor ventilation, cooking on open fires, over-crowding, lack of adequate child supervision. Women articulated the stress they experienced and clearly linked this to health conditions such as heart disease and uptake of smoking. They were also able to identify protective factors, particularly social capital. Subsequent analysis highlighted how female headed-households and those with disabilities had to contend with greater risks to health.Women living in slums are very aware of the intermediary determinants-material, behavioural and psycho-social, that increase their vulnerability to ill health. They are also able to identify protective factors, particularly social capital. It is only by understanding the determinants at all levels, not just the behavioural, that we will be able to identify

Clearance Kinetics and Clearance Routes of Molecules From the Suprachoroidal Space After Microneedle Injection.

To determine clearance kinetics and routes of clearance of molecules from the suprachoroidal space (SCS) of live New Zealand White rabbits. Suprachoroidal space collapse rate and pressure changes after microneedle injection into SCS were determined. Fluorescent fundus images were acquired to determine clearance rates of molecules ranging in size from 332 Da to 2 MDa. Microneedle injections of fluorescein were performed, and samples were taken from various sites over time to determine amount of fluorescein exiting the eye. Clearance transport was modeled theoretically and compared with experimental data. After injection, pressures in SCS and vitreous humor spiked and returned to baseline within 20 minutes; there was no difference between these two pressures. Suprachoroidal space collapse occurred within 40 minutes. One hour after fluorescein injection, 46% of fluorescein was still present in the eye, 15% had transported across sclera, 6% had been cleared by choroidal vasculature, and 4% had exited via leakage pathways. Characteristic clearance time increased in proportion with molecular radius, but total clearance of 2 MDa FITC-dextran was significantly slower (21 days) than smaller molecules. These data generally agreed with predictions from a theoretical model of molecular transport. Guided by experimental data in the context of model predictions, molecular clearance from SCS occurred in three regimes: (1) on a time scale of approximately 10 minutes, fluid and molecules exited SCS by diffusion into sclera and choroid, and by pressure-driven reflux via transscleral leakage sites; (2) in approximately 1 hour, molecules cleared from choroid by blood flow; and (3) in 1 to 10 hours, molecules cleared from sclera by diffusion and convection.

Full Text Available Abstract Background Knowledge of tuberculosis has been shown to influence health seeking behaviour; and urban slum dwellers are at a higher risk of acquiring tuberculosis than the general population. The study aim was to assess knowledge of tuberculosis and identify the associated socio-demographic determinants, in order to inform tailored interventions for advocacy, communication and social mobilisation in three urban-slum communities of Uganda. Methods A cross-sectional survey of 1361 adults between April and October 2011. Data was analyzed by descriptive statistics. Adjusted odds ratios (aOR and 95% confidence intervals (95% CI of potential determinants of tuberculosis (TB knowledge were estimated by multivariable ordinal logistic regression using Stata 11.2 software. Results We found low knowledge of TB cause (26.7%; symptoms (46.8%, transmission (54.3%, prevention (34% and free treatment (35%. Knowledge about TB treatment (69.4 and cure (85.1 was relatively high. Independent determinants of poor knowledge of TB in the multivariable analysis included (aOR, 95% CI lack of formal education (0.56; 0.38 – 0.83, P = 0.004, unemployment (0.67; 0.49 – 0.90, P = 0.010 and never testing for HIV (0.69; 0.51 – 0.92, P  Conclusion This study revealed deficiencies in the public health knowledge about TB symptoms, diagnosis and treatment among urban-slum dwellers in Uganda. Tuberculosis control programmes in similar settings should consider innovative strategies for TB education, advocacy, communication and social mobilisation to reach the youth, unemployed and less-educated; as well as those who have never tested for HIV.

Quantification of pathogenic Leptospira in the soils of a Brazilian urban slum.

Full Text Available Leptospirosis is an important zoonotic disease that causes considerable morbidity and mortality globally, primarily in residents of urban slums. While contact with contaminated water plays a critical role in the transmission of leptospirosis, little is known about the distribution and abundance of pathogenic Leptospira spp. in soil and the potential contribution of this source to human infection.We collected soil samples (n = 70 from three sites within an urban slum community endemic for leptospirosis in Salvador, Brazil. Using qPCR of Leptospira genes lipl32 and 16S rRNA, we quantified the pathogenic Leptospira load in each soil sample. lipl32 qPCR detected pathogenic Leptospira in 22 (31% of 70 samples, though the median concentration among positive samples was low (median = 6 GEq/g; range: 4-4.31×102 GEq/g. We also observed heterogeneity in the distribution of pathogenic Leptospira at the fine spatial scale. However, when using 16S rRNA qPCR, we detected a higher proportion of Leptospira-positive samples (86% and higher bacterial concentrations (median: 4.16×102 GEq/g; range: 4-2.58×104 GEq/g. Sequencing of the qPCR amplicons and qPCR analysis with all type Leptospira species revealed that the 16S rRNA qPCR detected not only pathogenic Leptospira but also intermediate species, although both methods excluded saprophytic Leptospira. No significant associations were identified between the presence of pathogenic Leptospira DNA and environmental characteristics (vegetation, rat activity, distance to an open sewer or a house, or soil clay content, though samples with higher soil moisture content showed higher prevalences.This is the first study to successfully quantify the burden of pathogenic Leptospira in soil from an endemic region. Our results support the hypothesis that soil may be an under-recognized environmental reservoir contributing to transmission of pathogenic Leptospira in urban slums. Consequently, the role of soil should be

To identify the factors influencing dropout from Ghana's health insurance scheme among populations living in slum communities. Cross-sectional data were collected from residents of 22 slums in the Accra Metropolitan Assembly. Cluster and systematic random sampling techniques were used to select and interview 600 individuals who had dropped out from the scheme 6 months prior to the study. Descriptive statistics and multivariate logistic regression models were computed to account for sample characteristics and reasons associated with the decision to dropout. The proportion of dropouts in the sample increased from the range of 6.8% in 2008 to 34.8% in 2012. Non-affordability of premium was the predominant reason followed by rare illness episodes, limited benefits of the scheme and poor service quality. Low-income earners and those with low education were significantly more likely to report premium non-affordability. Rare illness was a common reason among younger respondents, informal sector workers and respondents with higher education. All subgroups of age, education, occupation and income reported nominal benefits of the scheme as a reason for dropout. Interventions targeted at removing bottlenecks to health insurance enrolment are salient to maximising the size of the insurance pool. Strengthening service quality and extending the premium exemption to cover low-income families in slum communities is a valuable strategy to achieve universal health coverage. © 2014 John Wiley & Sons Ltd.

Serological Evidence of Hantavirus Infection in Apparently Healthy People from Rural and Slum Communities in Southern Chile

Full Text Available Hantavirus disease in America has been recognizable because of its rapid progression in clinical cases, occurrence in previously healthy young adults, and high case fatality rate. Hantavirus disease has been proposed now to define the diversity of clinical manifestations. Since 1995, a total of 902 cases of hantavirus pulmonary syndrome have been reported in Chile, caused by Andes virus (ANDV, with overall fatality of 32%. This report describes the sero-epidemiology of hantavirus in apparently healthy people in rural and urban slum communities from southern Chile. Ten of 934 samples yielded a positive result resulting in a seroprevalence of 1.07% (95% confidence intervals: 0.05%–2.0%. A higher proportion of positive samples was found among individuals from rural villages (1.3% and slums (1.5% compared with farms (0.5%. Seropositivity was associated with age (p = 0.011, low education level (p = 0.006 and occupations linked to the household (homemaker, retired, or student (p = 0.016. No evidence of infection was found in 38 sigmodontinae rodents trapped in the peri-domestic environment. Our findings highlight that exposure risk was associated with less documented risk factors, such as women in slum and rural villages, and the occurrence of infection that may have presented as flu-like illness that did not require medical attention or was misdiagnosed.

Leptospirosis has emerged as an urban health problem as slum settlements have rapidly spread worldwide and created conditions for rat-borne transmission. Prospective studies have not been performed to determine the disease burden, identify risk factors for infection and provide information needed to guide interventions in these marginalized communities. We enrolled and followed a cohort of 2,003 residents from a slum community in the city of Salvador, Brazil. Baseline and one-year serosurveys were performed to identify primary and secondary Leptospira infections, defined as respectively, seroconversion and four-fold rise in microscopic agglutination titers. We used multinomial logistic regression models to evaluate risk exposures for acquiring primary and secondary infection. A total of 51 Leptospira infections were identified among 1,585 (79%) participants who completed the one-year follow-up protocol. The crude infection rate was 37.8 per 1,000 person-years. The secondary infection rate was 2.3 times higher than that of primary infection rate (71.7 and 31.1 infections per 1,000 person-years, respectively). Male gender (OR 2.88; 95% CI 1.40-5.91) and lower per capita household income (OR 0.54; 95% CI, 0.30-0.98 for an increase of $1 per person per day) were independent risk factors for primary infection. In contrast, the 15-34 year age group (OR 10.82, 95% CI 1.38-85.08), and proximity of residence to an open sewer (OR 0.95; 0.91-0.99 for an increase of 1 m distance) were significant risk factors for secondary infection. This study found that slum residents had high risk (>3% per year) for acquiring a Leptospira infection. Re-infection is a frequent event and occurs in regions of slum settlements that are in proximity to open sewers. Effective prevention of leptospirosis will therefore require interventions that address the infrastructure deficiencies that contribute to repeated exposures among slum inhabitants.

Full Text Available Background: Diabetes was described more than 2000 years ago. For the past 250 years, it has featured in the history of medicine. Since the discovery of insulin, work on diabetes at both cellular and clinical levels has expanded. The worldwide prevalence of diabetes mellitus has risen dramatically in the developing countries over the past two decades. India with the highest absolute number of cases has become the diabetic capital of the world. Research question: What is the level of knowledge and awareness among adults regarding diabetes mellitus ? Objective: To study the level of knowledge and awareness regarding diabetes in adults of urban slum in Meerut. Study Design: Cross-sectional, Community-based study. Settings and Participants: Adults belonging to families of urban slum area of Multan nagar which also happens to be the field practice area of Department of Community Medicine, Subharti Medical College, Meerut. Sample Size: 400 young people aged above 25years, 220 respondents were males and 180 were females. Study Period: Feb 2011 to July 2011 Study Variables: A pre- designed, pre-tested, questionnaire was used after taking verbal consent. Questions consisted of age, sex, knowledge and awareness of diabetes i.e. whether ever heard of diabetes, causes, signs and symptoms, mode of diagnosis, complications, risk factors, mode of treatment, source of information regarding diabetes. Statistical Analysis: Data was entered and analyzed in MS Excel. For Socio-economic status, Modified Kuppuswamy classification was used. Results: 75% of the respondents had heard of diabetes.

In spite of major gains in contraceptive prevalence over the last few decades, many women in most parts of the developing world who would like to delay or avoid pregnancy do not use any method of contraception. This paper seeks to: a) examine whether experiencing an unintended pregnancy is associated with future use of contraception controlling for a number factors including poverty at the household and community levels; and b) investigate the mechanisms through which experiencing an unintended pregnancy leads to uptake of contraception. Quantitative and qualitative data from a cross-sectional research project conducted in 2009/10 in two slum settlements and two non-slum settings of Nairobi, Kenya are used. The quantitative component of the project was based on a random sample of 1,259 women aged 15-49 years. Logistic regression models were used to assess the effect of unintended pregnancy on future contraceptive use. The qualitative component of the project successfully interviewed a total of 80 women randomly selected from survey participants who had reported having at least one unintended pregnancy. Women whose last pregnancy was unintended were more likely to be using a modern method of contraception, compared to their peers whose last pregnancy was intended, especially among the wealthier group as shown in the interaction model. Among poor women, unintended pregnancy was not associated with subsequent use of contraception. The qualitative investigation with women who had an unplanned pregnancy reveals that experiencing an unintended pregnancy seems to have served as a "wake-up call", resulting in greater attention to personal risks, including increased interest in pregnancy prevention. For some women, unintended pregnancy was a consequence of strong opposition by their partners to family planning, while others reported they started using contraceptives following their unintended pregnancy, but discontinued after experiencing side effects.

Urban slum environments in the tropics are conducive to the proliferation and the spread of rodent-borne zoonotic pathogens to humans. Calodium hepaticum (Brancroft, 1893) is a zoonotic nematode known to infect a variety of mammalian hosts, including humans. Norway rats (Rattus norvegicus) are considered the most important mammalian host of C. hepaticum and are therefore a potentially useful species to inform estimates of the risk to humans living in urban slum environments. There is a lack of studies systematically evaluating the role of demographic and environmental factors that influence both carriage and intensity of infection of C. hepaticum in rodents from urban slum areas within tropical regions. Carriage and the intensity of infection of C. hepaticum were studied in 402 Norway rats over a 2-year period in an urban slum in Salvador, Brazil. Overall, prevalence in Norway rats was 83% (337/402). Independent risk factors for C. hepaticum carriage in R. norvegicus were age and valley of capture. Of those infected the proportion with gross liver involvement (i.e. >75% of the liver affected, a proxy for a high level intensity of infection), was low (8%, 26/337). Sixty soil samples were collected from ten locations to estimate levels of environmental contamination and provide information on the potential risk to humans of contracting C. hepaticum from the environment. Sixty percent (6/10) of the sites were contaminated with C. hepaticum. High carriage levels of C. hepaticum within Norway rats and sub-standard living conditions within slum areas may increase the risk to humans of exposure to the infective eggs of C. hepaticum. This study supports the need for further studies to assess whether humans are becoming infected within this community and whether C. hepaticum is posing a significant risk to human health.

To estimate the incremental economic costs and explore satisfaction with a highly effective intervention for improving immunization coverage among slum populations in Dhaka, Bangladesh. A package of interventions based on extended clinic hours, vaccinator training, active surveillance, and community participation was piloted in two slum areas of Dhaka, and resulted in an increase in valid fully immunized children (FIC) from 43% pre-intervention to 99% post-intervention. Cost data and stakeholder perspectives were collected January-February 2010 via document review and 10 key stakeholders interviews to estimate the financial and opportunity costs of the intervention, including uncompensated time, training and supervision costs. The total economic cost of the 1-year intervention was $18,300, comprised of external management and supervision (73%), training (11%), coordination costs (1%), uncompensated staff time and clinic costs (2%), and communications, supplies and other costs (13%). An estimated 874 additional children were correctly and fully immunized due to the intervention, at an average cost of $20.95 per valid FIC. Key stakeholders ranked extended clinic hours and vaccinator training as the most important components of the intervention. External supervision was viewed as the most important factor for the intervention's success but also the costliest. All stakeholders would like to reinstate the intervention because it was effective, but additional funding would be needed to make the intervention sustainable. Targeting slum populations with an intensive immunization intervention was highly effective but would nearly triple the amount spent on immunization per FIC in slum areas. Those committed to increasing vaccination coverage for hard-to-reach children need to be prepared for substantially higher costs to achieve results. Copyright © 2014. Published by Elsevier Ltd.

Air pollution is among the leading global risks for mortality and responsible for increasing risk for chronic diseases. Community perceptions on exposure are critical in determining people’s response and acceptance of related policies. Therefore, understanding people’ perception is critical in informing the design of appropriate intervention measures. The aim of this paper was to establish levels and associations between perceived pollution and health risk perception among slum residents. A cross-sectional study of 5,317 individuals aged 35+ years was conducted in two slums of Nairobi. Association of perceived score and individual characteristics was assessed using linear regression. Spatial variation in the perceived levels was determined through hot spot analysis using ArcGIS. The average perceived air pollution level was higher among residents in Viwandani compared to those in Korogocho. Perceived air pollution level was positively associated with perceived health risks. The majority of respondents were exposed to air pollution in their place of work with 66% exposed to at least two sources of air pollution. Less than 20% of the respondents in both areas mentioned sources related to indoor pollution. The perceived air pollution level and related health risks in the study community were lowamong the residents indicating the need for promoting awareness on air pollution sources and related health risks.

Throughout the developing world, urban centers with sprawling slum settlements are rapidly expanding and invading previously forested ecosystems. Slum communities are characterized by untended refuse, open sewers, and overgrown vegetation, which promote rodent infestation. Norway rats (Rattus norvegicus), are reservoirs for epidemic transmission of many zoonotic pathogens of public health importance. Understanding the population ecology of R. norvegicus is essential to formulate effective rodent control strategies, as this knowledge aids estimation of the temporal stability and spatial connectivity of populations. We screened for genetic variation, characterized the population genetic structure, and evaluated the extent and patterns of gene flow in the urban landscape using 17 microsatellite loci in 146 rats from 9 sites in the city of Salvador, Brazil. These sites were divided between three neighborhoods within the city spaced an average of 2.7 km apart. Surprisingly, we detected very little relatedness among animals trapped at the same site and found high levels of genetic diversity, as well as structuring across small geographic distances. Most FST comparisons among sites were statistically significant, including sites Salvador, linked to the heterogeneous urban landscape. Future rodent control measures need to take into account the spatial and temporal linkage of rat populations in Salvador, as revealed by genetic data, to develop informed eradication strategies.

Urban area like Dhaka City, in Bangladesh, has scarcity of safe drinking water which is one of the prominent basic needs for human kind. This study explored the acceptability of harvested rainwater in a densely populated city like Dhaka, using a simple and low cost technology. A total of 200 random people from four slums of water-scarce Dhaka City were surveyed to determine the dwellers' perception on rainwater and its acceptability as a source of drinking water. The questionnaire was aimed at finding the socio-economic condition and the information on family housing, sanitation, health, existing water supply condition, knowledge about rainwater, willingness to accept rainwater as a drinking source etc. A Yield before Spillage (YBS) model was developed to know the actual rainwater availability and storage conditions which were used to justify the effective tank size. Cost-benefit analysis and feasibility analysis were performed using the survey results and the research findings. The survey result and overall study found that the low cost rainwater harvesting technique was acceptable to the slum dwellers as only the potential alternative source of safe drinking water.

Full Text Available Inadequate urban sanitation disproportionately impacts the social determinants of women’s health in informal settlements or slums. The impacts on women’s health include infectious and chronic illnesses, violence, food contamination and malnutrition, economic and educational attainment, and indignity. We used household survey data to report on self-rated health and sociodemographic, housing, and infrastructure conditions in the Mathare informal settlement in Nairobi, Kenya. We combined quantitative survey and mapping data with qualitative focus group information to better understand the relationships between environmental sanitation and the social determinants of women and girls’ health in the Mathare slum. We find that an average of eighty-five households in Mathare share one toilet, only 15% of households have access to a private toilet, and the average distance to a public toilet is over 52 meters. Eighty-three percent of households without a private toilet report poor health. Mathare women report violence (68%, respiratory illness/cough (46%, diabetes (33%, and diarrhea (30% as the most frequent physical burdens. Inadequate, unsafe, and unhygienic sanitation results in multiple and overlapping health, economic, and social impacts that disproportionately impact women and girls living in urban informal settlements.

Depression among elderly is emerging as an important public health issue in developing countries like India. Published evidence regarding the magnitude and determinants of depression among elderly hailing from urban slum is currently limited. Hence, the current study was conducted to assess magnitude of the problem and identify factors associated with depression among the elderly in an urban slum. A cross-sectional study was done to cover total of 473 elderly persons from an urban slum in Bangalore, India. They were assessed for depression using Center for Epidemiologic Studies Depression scale. The overall prevalence of depression was found to be 37.8 (95% CI = 33.43-42.16). Multivariate analysis revealed that unemployment (self or children) (odds ratio (OR) 2.6; 95% confidence interval (CI) 1.41-4.72), illness of self (OR 2.2; 95% CI 1.45-3.21), female gender (OR 1.9; 95% CI 1.19-2.89), conflicts in family (OR 1.6; 95% CI 1.03-2.43), and marriage of children or grandchildren (OR 1.6; 95% CI 1.02-2.68) as independent risk factors. Depression among elderly is an important health issue of this area. Psychological intervention need to be provided for all elderly persons especially at the time of being diagnosed with any kind of illness. Strategies should be targeted to the females. The stressful life events need to be identified and remedial actions taken. This facility should be made available to them at the primary level of health care. There is a need to include screening of depression in our national health programs.

Cities around the world are undergoing rapid urbanization, resulting in the growth of informal settlements or slums. These informal settlements lack basic services, including sanitation, and are associated with joblessness, low-income levels, and insecurity. Families living in such settlements may turn to a variety of strategies to improve their livelihoods and household food security, including urban agriculture. However, given the lack of formal sanitation services in most of these informal settlements, residents are frequently exposed to a number of environmental risks, including biological and chemical contaminants. In the Kibera slums of Nairobi, Kenya, households practice a form of urban agriculture called sack gardening, or vertical gardening, where plants such as kale and Swiss chard are planted into large sacks filled with soil. Given the nature of farming in slum environments, farmers and consumers of this produce in Kibera are potentially exposed to a variety of environmental contaminants due to the lack of formal sanitation systems. Our research demonstrates that perceived and actual environmental risks, in terms of contamination of food crops from sack gardening, are not the same. Farmers perceived exposure to biological contaminants to be the greatest risk to their food crops, but we found that heavy metal contamination was also significant risk. By demonstrating this disconnect between risk perception and actual risk, we wish to inform debates about how to appropriately promote urban agriculture in informal settlements, and more generally about the trade-offs created by farming in urban spaces.

Clearance and release from control - An international perspective

Thierfeldt, S.

2005-01-01

This paper tries to give an overview of the clearance, or release from regulatory control, on an international scale, including some of those countries where clearance has become or is about to become vital for D and D. The emphasis lies on the impact of clearance, and in particular of differences between clearance levels of various countries, on D and D. Relevance of clearance for D and D of nuclear installations Clearance is an essential part of waste management (or more general, material management) in nuclear installations, and in particular during the decommissioning phase where waste streams continues to arise. Of course, the relevance of clearance in a particular country depends on a number of factors, like: availability of a final repository and its price; prevailing decommissioning strategy; number of nuclear installations reaching decommissioning phase. This small selection of reasons why clearance may be of varying importance for different countries may already suffice to illustrate why up to now clearance has been developed and implemented in quite different ways. If one thinks of additional reasons that may influence clearance, like politics, the public opinion, availability of funds etc., the situation becomes even more complex. It is, however safe to draw the conclusion that countries with a certain number of nuclear installations which have been or will soon be shut down or which are already in the decommissioning phase will need to implement provisions for clearance. This has indeed been the case with countries like the UK, Germany, the USA, Sweden, and a number of others. It is not essential for clearance levels to be exactly equal between various countries. They may differ as long as the difference is not too large, e.g. the values fall into the same order of magnitude. This is the reason why for example Germany has no problems with clearance levels which differ from the EU recommendation RP 122 partially adopted in a number of EU countries

The transport of excessive phosphorus (P) discharged from unsewered informal settlements (slums) due to poor on-site sanitation is largely unknown. Hence, we investigated the processes governing P transport in a 28 km2 slum-dominated catchment in Kampala, Uganda. During high runoff events and a period of base flow, we collected hourly water samples (over 24 h) from a primary channel draining the catchment and from a small size tertiary channel draining one of the contributing slum areas (0.5 km2). Samples were analyzed for orthophosphate (PO4-P), particulate P (PP), total P (TP) and selected hydro-chemical parameters. Channel bed and suspended sediments were collected to determine their sorption potential, geo-available metals and dominant P forms. We found that P inputs in the catchment originated mainly from domestic wastewater as evidenced by high concentrations of Cl (36-144 mg L-1), HCO3 and other cations in the channels. Most P discharged during low flow conditions was particulate implying that much of it was retained in bed sediments. Retained P was mostly bound to Ca and Fe/Al oxides. Hence, we inferred that mineral precipitation and adsorption to Ca-minerals were the dominant P retention processes. Bed sediments were P-saturated and showed a tendency to release P to discharging waters. P released was likely due to Ca-bound P because of the strong correlation between Ca and total P in sediments (r2 = 0.9). High flows exhibited a strong flush of PP and SS implying that part of P retained was frequently flushed out of the catchment by surface erosion and resuspension of bed sediment. Our findings suggest that P accumulated in the channel bed during low flows and then was slowly released into surface water. Hence, it will likely take some time, even with improved wastewater management practices, before P loads to downstream areas can be significantly reduced.

The four common non-communicable diseases (NCDs) account for 80% of NCD-related deaths worldwide. The four NCDs share four common risk factors. As most of the existing evidence on the common NCD risk factors is based on analysis of a single factor at a time, there is a need to investigate the co-occurrence of the common NCD risk factors, particularly in an urban slum setting in sub-Saharan Africa. To determine the prevalence of co-occurrence of the four common NCDs risk factors among urban slum dwellers in Nairobi, Kenya. This analysis was based on the data collected as part of a cross-sectional survey to assess linkages among socio-economic status, perceived personal risk, and risk factors for cardiovascular and NCDs in a population of slum dwellers in Nairobi, Kenya, in 2008-2009. A total of 5,190 study subjects were included in the analysis. After selecting relevant variables for common NCD risk factors, we computed the prevalence of all possible combinations of the four common NCD risk factors. The analysis was disaggregated by relevant background variables. The weighted prevalences of unhealthy diet, insufficient physical activity, harmful use of alcohol, and tobacco use were found to be 57.2, 14.4, 10.1, and 12.4%, respectively. Nearly 72% of the study participants had at least one of the four NCD risk factors. About 52% of the study population had any one of the four NCD risk factors. About one-fifth (19.8%) had co-occurrence of NCD risk factors. Close to one in six individuals (17.6%) had two NCD risk factors, while only 2.2% had three or four NCD risk factors. One out of five of people in the urban slum settings of Nairobi had co-occurrence of NCD risk factors. Both comprehensive and differentiated approaches are needed for effective NCD prevention and control in these settings.

Diarrhoeal infections are the fifth leading cause of death worldwide and continue to take a high toll on child health. Mushrooming of slums due to continuous urbanization has made diarrhoea one of the biggest public-health challenges in metropolitan cities in India. The objective of the study was to carry out a community-based health and nutrition-education intervention, focusing on several factors influencing child health with special emphasis on diarrhoea, in a slum of Delhi, India. Mothers (n=370) of children, aged >12-71 months, identified by a door-to-door survey from a large urban slum, were enrolled in the study in two groups, i.e. control and intervention. To ensure minimal group interaction, enrollment for the control and intervention groups was done purposively from two extreme ends of the slum cluster. Baseline assessment of knowledge, attitudes, and practices on diarrhoea-related issues, such as oral rehydration therapy (ORT), oral rehydration salt (ORS), and continuation of breastfeeding during diarrhoea, was carried out using a pretested questionnaire. Thereafter, mothers (n=195) from the intervention area were provided health and nutrition education through fortnightly contacts achieved by two approaches developed for the study--'personal discussion sessions' and 'lane approach'. The mothers (n=175) from the control area were not contacted. After the intervention, there was a significant (p=0.000) improvement in acquaintance to the term 'ORS' (65-98%), along with its method of reconstitution from packets (13-69%); preparation of home-made sugar-salt solution (10-74%); role of both in the prevention of dehydration (30-74%) and importance of their daily preparation (74-96%); and continuation of breastfeeding during diarrhoea (47-90%) in the intervention area. Sensitivity about age-specific feeding of ORS also improved significantly (p=0.000) from 13% to 88%. The reported usage of ORS packets and sugar-salt solution improved significantly from 12% to 65

Unsightly urban menaces and the rescaling of residential segregation in the United States.

Science.gov (United States)

Hanlon, James

2011-01-01

In this article, the author uses a slum clearance project in Lexington, Kentucky, as a lens through which to examine the spatial dynamics of racial residential segregation during the first half of the twentieth century. At the time, urban migration and upward socioeconomic mobility on the part of African Americans destabilized extant residential segregation patterns. Amid this instability, various spatial practices were employed in the interest of maintaining white social and economic supremacy. The author argues that such practices were indicative of a thoroughgoing reinvention of urban socio-spatial order that in turn precipitated the vastly expanded scale of residential segregation still found in U.S. cities today. Evidence of this reinvented ordering of urban space lies in the rendering of some long-standing African American neighborhoods as “out of place” within it and the use of slum clearance to remove the “menace” such neighborhoods posed to it.

Access to improved drinking water, sanitation and hygiene is one of the prime concerns around the globe. This study aimed at assessing water and sanitation hygiene-related attitude and practices, and quality of water in urban slums of south Delhi, India. This pilot cross sectional study was performed during July 2013 across four urban slums of South Delhi. A convenient sample of 40 participants was enrolled. A modified version of previously validated questionnaire was used to gather information on socio-demographics, existing water and sanitation facilities and water treatment practices. Water quality testing was additionally performed using hydrogen sulphide (H2S) vials. Average age of participants was 36 years (SD=10). 83% of the participants perceived gastrointestinal tract infection as the most important health problem. 75% of the participants did not use any method for drinking water treatment. 45% of the participants consumed water from privately-owned tube well/ bore well. Water shortage lasted two days or more (50%) at a stretch with severe scarcity occurring twice a year (40%). Females aged 15 years and above were largely responsible (93%) for fetching water from water source. 45% of the participants had toilets within their households. 53% of drinking water samples collected from storage containers showed positive bacteriological contamination. There is an urgent need to develop family centered educational programs that would enhance awareness about water treatment methods that are cost effective and easily accessible.

Few studies of dengue have shown group-level associations between demographic, socioeconomic, or geographic characteristics and the spatial distribution of dengue within small urban areas. This study aimed to examine whether specific characteristics of an urban slum community were associated with the risk of dengue disease. From 01/2009 to 12/2010, we conducted enhanced, community-based surveillance in the only public emergency unit in a slum in Salvador, Brazil to identify acute febrile illness (AFI) patients with laboratory evidence of dengue infection. Patient households were geocoded within census tracts (CTs). Demographic, socioeconomic, and geographical data were obtained from the 2010 national census. Associations between CTs characteristics and the spatial risk of both dengue and non-dengue AFI were assessed by Poisson log-normal and conditional auto-regressive models (CAR). We identified 651 (22.0%) dengue cases among 2,962 AFI patients. Estimated risk of symptomatic dengue was 21.3 and 70.2 cases per 10,000 inhabitants in 2009 and 2010, respectively. All the four dengue serotypes were identified, but DENV2 predominated (DENV1: 8.1%; DENV2: 90.7%; DENV3: 0.4%; DENV4: 0.8%). Multivariable CAR regression analysis showed increased dengue risk in CTs with poorer inhabitants (RR: 1.02 for each percent increase in the frequency of families earning ≤1 times the minimum wage; 95% CI: 1.01-1.04), and decreased risk in CTs located farther from the health unit (RR: 0.87 for each 100 meter increase; 95% CI: 0.80-0.94). The same CTs characteristics were also associated with non-dengue AFI risk. This study highlights the large burden of symptomatic dengue on individuals living in urban slums in Brazil. Lower neighborhood socioeconomic status was independently associated with increased risk of dengue, indicating that within slum communities with high levels of absolute poverty, factors associated with the social gradient influence dengue transmission. In addition, poor

We hypothesized that wastewater leaching from on-site sanitation systems to alluvial aquifers underlying informal settlements (or slums) may end up contributing to high nutrient loads to surface water upon groundwater exfiltration. Hence, we conducted a hydro-geochemical study in a shallow sandy aquifer in Bwaise III parish, an urban slum area in Kampala, Uganda, to assess the geochemical processes controlling the transport and fate of dissolved nutrients (NO3, NH4 and PO4) released from on-site sanitation systems to groundwater. Groundwater was collected from 26 observation wells. The samples were analyzed for major ions (Ca, Mg, Na, Mg, Fe, Mn, Cl and SO4) and nutrients (o-PO4, NO3 and NH4). Data was also collected on soil characteristics, aquifer conductivity and hydraulic heads. Geochemical modeling using PHREEQC was used to determine the level of o-PO4 control by mineral solubility and sorption. Groundwater below the slum area was anoxic and had near neutral pH values, high values of EC (average of 1619 μS/cm) and high concentrations of Cl (3.2 mmol/L), HCO3 (11 mmol/L) and nutrients indicating the influence from wastewater leachates especially from pit latrines. Nutrients were predominantly present as NH4 (1-3 mmol/L; average of 2.23 mmol/L). The concentrations of NO3 and o-PO4 were, however, low: average of 0.2 mmol/L and 6 μmol/L respectively. We observed a contaminant plume along the direction of groundwater flow (NE-SW) characterized by decreasing values of EC and Cl, and distinct redox zones. The redox zones transited from NO3-reducing in upper flow areas to Fe-reducing in the lower flow areas. Consequently, the concentrations of NO3 decreased downgradient of the flow path due to denitrification. Ammonium leached directly into the alluvial aquifer was also partially removed because the measured concentrations were less than the potential input from pit latrines (3.2 mmol/L). We attributed this removal (about 30%) to anaerobic ammonium oxidation

Little, David A.; Pu, Zhengxiang

2015-08-18

A compressor airfoil tip clearance optimization system for reducing a gap between a tip of a compressor airfoil and a radially adjacent component of a turbine engine is disclosed. The turbine engine may include ID and OD flowpath boundaries configured to minimize compressor airfoil tip clearances during turbine engine operation in cooperation with one or more clearance reduction systems that are configured to move the rotor assembly axially to reduce tip clearance. The configurations of the ID and OD flowpath boundaries enhance the effectiveness of the axial movement of the rotor assembly, which includes movement of the ID flowpath boundary. During operation of the turbine engine, the rotor assembly may be moved axially to increase the efficiency of the turbine engine.

Slum-resettlement communities are increasingly adopting urban lifestyles. The aim of this study was to assess the prevalence and identify correlates of hypertension among residents aged 20-59 years of a slum-resettlement colony. A community-based cross-sectional study was done from 2010 to 2012 in NandNagri, a slum-resettlement area in east Delhi. 310 participants aged 20-59 years were enrolled through multistage systematic random sampling. Each study subject was interviewed and examined for raised blood pressure; data on risk factors including smoking, alcohol intake, physical activity and salt consumption were also collected. Data were analysed by use of univariate and multivariate regression. The overall prevalence of hypertension was 17.4% and 35% participants were prehypertensive. On multiple logistic regression, age 40-49 years (P = 0.020) and 50-59 years (P = 0.012), clerical/professional occupation (P = 0.004), abnormal waist circumference (≥90 cm in males and ≥ 80 cm in females; P = 0.001), positive family history of hypertension in both parents (P = 0.013) and above-average daily salt intake (P = 0.000) were significantly associated with hypertension. These findings indicate that hypertension is a significant health problem in the study population. Many study participants diagnosed with prehypertension are at risk of developing hypertension, thus immediate public-health interventions are indicated.

Full Text Available Maya Laxmi Patel, Raywat Deonandan Interdisciplinary School of Health Sciences, University of Ottawa, Ottawa, ON, Canada Background: Urbanization is increasing around the world, and in India, this trend has translated into an increase in the size of slum dwellings whose environments are suspected of being associated with poor health outcomes, particularly those relating to women’s nutritional status. With this study, we sought to determine the factors associated with Indian women’s body mass index (BMI in slum environments, with special attention paid to women with tribal status.Methods: A multiple linear regression analysis was performed on data from the Indian National Family Health Survey (2005–2006, modeling demographic and behavioral factors suspected of being associated with BMI, with additional focus on the measures of social class, specifically caste and tribal status.Results: Increasing BMI is significantly and positively associated with frequency of watching television, having diabetes, age, wealth index, and residency status in the areas of New Delhi, Andhra Pradesh, or Tamil Nadu.Conclusion: Although belonging to a scheduled tribe was not associated with changes in BMI, unadjusted rates suggest that tribal status may be worthy of deeper investigation. Among slum dwellers, there is a double burden of undernutrition and overnutrition. Therefore, a diverse set of interventions may be required to improve the health outcomes of these women.

Noninvasive determination of individual renal clearance

International Nuclear Information System (INIS)

Chanard, J.; Brunois, J.P.; Ruiz, J.C.; Assailly, J.

1980-01-01

A noninvasive method for measurement of individual renal clearance is presented, based on analysis of the early rise of the kidneys' time-activity curves after injection of an appropriate tracer ( 131 I-ortho-iodohippurate for tubular function or 111 In DTPA for glomerular clearance). The analysis is based on the assumption that an insignificant amount of tracer leaves the kidney during the first few moments following injection. Therefore, the kidney activity during this period is directly proportional to the integral of the blood (heart) activity. After blood background subtraction, the linear correlation between the early part of the renogram and the corresponding blood integral activity curve allows calculation of an angular coefficient. The ratio of these coefficients calculated for each kidney is proportional to the ratio of the individual clearances. The latter are calculated from the total clearance simultaneously measured using a simplified method without urine collection. In control subjects with normal renal function individual renal clearances were not significantly different. In uninephrectomized patients a precision of 5% in calculating individual clearance was estimated from data recorded at the level of the remaining kidney. In patients with functional asymmetry, results were compared with 197 HgCl 2 quantitative renal fixation. A linear correlation was found (r = 0.95). The method we propose seems valuable for clinical investigation and allows sequential measurements. (orig.)

Decentralised grey water treatment in urban slums using low-cost and robust technologies offers opportunities to minimise public health risks and to reduce environmental pollution caused by the highly polluted grey water i.e. with a COD and N concentration of 3000-6000 mg L(-1) and 30-40 mg L(-1), respectively. However, there has been very limited action research to reduce the pollution load from uncontrolled grey water discharge by households in urban slums. This study was therefore carried out to investigate the potential of a two-step filtration process to reduce the grey water pollution load in an urban slum using a crushed lava rock filter, to determine the main filter design and operation parameters and the effect of intermittent flow on the grey water effluent quality. A two-step crushed lava rock filter unit was designed and implemented for use by a household in the Bwaise III slum in Kampala city (Uganda). It was monitored at a varying hydraulic loading rate (HLR) of 0.5-1.1 m d(-1) as well as at a constant HLR of 0.39 m d(-1). The removal efficiencies of COD, TP and TKN were, respectively, 85.9%, 58% and 65.5% under a varying HLR and 90.5%, 59.5% and 69%, when operating at a constant HLR regime. In addition, the log removal of Escherichia coli, Salmonella spp. and total coliforms was, respectively, 3.8, 3.2 and 3.9 under the varying HLR and 3.9, 3.5 and 3.9 at a constant HLR. The results show that the use of a two-step filtration process as well as a lower constant HLR increased the pollutant removal efficiencies. Further research is needed to investigate the feasibility of adding a tertiary treatment step to increase the nutrients and microorganisms removal from grey water. Copyright © 2013 Elsevier Ltd.

A model of clearance rate regulation in mussels

Science.gov (United States)

Fréchette, Marcel

2012-10-01

Clearance rate regulation has been modelled as an instantaneous response to food availability, independent of the internal state of the animals. This view is incompatible with latent effects during ontogeny and phenotypic flexibility in clearance rate. Internal-state regulation of clearance rate is required to account for these patterns. Here I develop a model of internal-state based regulation of clearance rate. External factors such as suspended sediments are included in the model. To assess the relative merits of instantaneous regulation and internal-state regulation, I modelled blue mussel clearance rate and growth using a DEB model. In the usual standard feeding module, feeding is governed by a Holling's Type II response to food concentration. In the internal-state feeding module, gill ciliary activity and thus clearance rate are driven by internal reserve level. Factors such as suspended sediments were not included in the simulations. The two feeding modules were compared on the basis of their ability to capture the impact of latent effects, of environmental heterogeneity in food abundance and of physiological flexibility on clearance rate and individual growth. The Holling feeding module was unable to capture the effect of any of these sources of variability. In contrast, the internal-state feeding module did so without any modification or ad hoc calibration. Latent effects, however, appeared transient. With simple annual variability in temperature and food concentration, the relationship between clearance rate and food availability predicted by the internal-state feeding module was quite similar to that observed in Norwegian fjords. I conclude that in contrast with the usual Holling feeding module, internal-state regulation of clearance rate is consistent with well-documented growth and clearance rate patterns.

The inadequate provision of sanitation in informal urban settlements, also known as slums, continues to be an important issue. New technologies and services are being designed to solve this problem. However, the history of failed sanitation programmes and projects highlights a lack of understanding of how slum inhabitants decide on investing in such products and services. In this paper, we gather perspectives from potential clients and investigate how slum inhabitants (1) perceive the current situation and whether they desire improvements of sanitation, (2) how they evaluate a new toilet that is still in development, and how (3) social processes and (4) constraints affect decisions. Data were collected through interviewing 1538 people within a general household survey. People using shared and public latrines desire an improvement of their sanitation facilities. The lack of water for washing is perceived by residents as a the biggest problem when accessing current latrines. The new toilet was mostly evaluated positively: people like it, expect large health benefits from it and it complies with cultural norms. However, people also expect some problems with the functioning of the toilet and expect opposition to pay for the service, due to the high costs and a lack of space to set up new toilets.

This work explores the utility of the cynomolgus monkey as a preclinical model to predict hepatic uptake clearance mediated by organic anion transporting polypeptide (OATP) transporters. Nine OATP substrates (rosuvastatin, pravastatin, repaglinide, fexofenadine, cerivastatin, telmisartan, pitavastatin, bosentan and valsartan) were investigated in plated cynomolgus monkey and human hepatocytes. Total uptake clearance and passive diffusion were measured in vitro from initial rates in the absence and presence of the OATP inhibitor rifamycin SV, respectively. Total uptake clearance values in plated hepatocytes ranged over three orders of magnitude in both species with a similar rank order and good agreement in the relative contribution of active transport to total uptake between cynomolgus monkey and human. In vivo hepatic clearance for these nine drugs was determined in cynomolgus monkey after intravenous dosing. Hepatic clearances showed a similar range to human parameters and good predictions from respective hepatocyte parameters (with 2.7 and 3.8-fold bias on average, respectively). The use of cross species empirical scaling factors (based on either dataset average or individual drug scaling factor from cynomolgus monkey data) improved prediction (less bias, better concordance) of human hepatic clearance from human hepatocyte data alone. In vitro intracellular binding in hepatocytes also correlated well between species. It is concluded that the minimal species differences observed for the current dataset between cynomolgus monkey and human hepatocyte uptake, both in vitro and in vivo, support future use of this preclinical model to delineate drug hepatic uptake and enable prediction of human in vivo intrinsic hepatic clearance.

Urban slum populations in Africa continue to grow faster than national populations. Health strategies that focus on non-communicable diseases (NCD) in this segment of the population are generally lacking. We determined the prevalence of diabetes and associated cardiovascular disease (CVD) risk factors correlates in Kibera, Nairobi's largest slum. We conducted a population-based household survey utilising cluster sampling with probability proportional to size. Households were selected using a random walk method and consenting residents aged 18 years and above were recruited. The WHO STEPS instrument was administered. A random capillary blood sugar (RCBS) was obtained; known persons with diabetes and subjects with a RCBS >11.1 had an 8 hours fasting blood sugar (FBS) drawn. Diabetes was defined as a RCBS of  ≥ 11.1 mmol/l and a FBS of  ≥ 7.0 mmol/l, or a prior diagnosis or receiving diabetes drug treatment. Out of 2061 enrolled; 50.9% were males, mean age was 33.4 years and 87% had a minimum of primary education. Only 10.6% had ever had a blood sugar measurement. Age adjusted prevalence of diabetes was 5.3% (95% CI 4.2-6.4) and prevalence increased with age peaking at 10.5% (95% CI 6.8-14.3%) in the 45-54 year age category. Diabetes mellitus (DM) correlates were: 13.1% smoking, 74.9% alcohol consumption, 75.7% high level of physical activity; 16.3% obese and 29% overweight with higher rates in women.Among persons with diabetes the odds of obesity, elevated waist circumference and hypertension were three, two and three fold respectively compared to those without diabetes. Cardiovascular risk factors among subjects with diabetes were high and mirrored that of the entire sample; however they had a significantly higher use of tobacco. This previously unstudied urban slum has a high prevalence of DM yet low screening rates. Key correlates include cigarette smoking and high alcohol consumption. However high levels of physical activity were also reported. Findings

2018-02-01

Following recent advances in distinguishing settlements vs. non-settlement areas from latest SAR data, the question arises whether a further automatic intra-urban delineation and characterization of different structural types is possible. This paper studies the appearance of the structural type ;slums; in high resolution SAR images. Geocoded Kennaugh elements are used as backscatter information and Schmittlet indices as descriptor of local texture. Three cities with a significant share of slums (Cape Town, Manila, Mumbai) are chosen as test sites. These are imaged by TerraSAR-X in the dual-co-polarized high resolution spotlight mode in any available aspect angle. Representative distributions are estimated and fused by a robust approach. Our observations identify a high similarity of slums throughout all three test sites. The derived similarity maps are validated with reference data sets from visual interpretation and ground truth. The final validation strategy is based on completeness and correctness versus other classes in relation to the similarity. High accuracies (up to 87%) in identifying morphologic slums are reached for Cape Town. For Manila (up to 60%) and Mumbai (up to 54%), the distinction is more difficult due to their complex structural configuration. Concluding, high resolution SAR data can be suitable to automatically trace potential locations of slums. Polarimetric information and the incidence angle seem to have a negligible impact on the results whereas the intensity patterns and the passing direction of the satellite are playing a key role. Hence, the combination of intensity images (brightness) acquired from ascending and descending orbits together with Schmittlet indices (spatial pattern) promises best results. The transfer from the automatically recognized physical similarity to the semantic interpretation remains challenging.

Changes in 131 I hippuran clearance were estimated by a non-catheter method, as well as total clearance and clearance of each kidney, in 43 women at various stages of pregnancy and in 13 non-pregnant women who were not using hormonal contraceptives. The results are demonstrated in graph form. The methods used are described in detail. The procedure for determining clearance in separate kidneys is indicated. It was found that clearance values increased up to the 35th and 26th weeks of pregnancy.

Full Text Available Background: Sexually transmitted diseases are very important health challenges for adolescents. Many national and international governmental and nongovernmental health agencies are running programmes to reduce the incidence of these diseases. We can provide an insight to the reproductive and sexual health needs of adolescents by assessing their knowledge, attitude and practice about these diseases. Research Question: What is the level of knowledge awareness and practice among adolescents regarding sexually transmitted diseases?  Objectives: To assess the knowledge awareness and practice among adolescents regarding sexually transmitted diseases in an urban slum in Dehradun. Study Design: Cross-Sectional Settings and Participants: Adolescents belonging to registered families of Chandreshwar Nagar urban slum under the field practice area of Urban Health Training Centre (UHTC of department of Community Medicine, Himalayan Institute of Medical Sciences. Sample Size: 166 Adolescents i.e. Males-88 and Females-78. Study Period: May 2009 to October 2009 Study Variable: A predesigned, pretested, self-administered questionnaire was used for collecting information on Age, Sex, Knowledge and awareness regarding STDs, etc. Statistical Analysis: Standard statistical package i.e. SPSS, Microsoft Excel.  Results: 51.2% of the adolescents were having knowledge about STD’s.

Conclusions: Appropriate health care seeking behaviour and Information Education and Communication (IEC activities should be promoted.

Establishing exemption and clearance criteria by the regulatory authority

International Nuclear Information System (INIS)

Salih, A.E.A.

2012-04-01

This Project work discusses the relationship between the concepts of exemption and clearance, and their practical use in the overall scheme of regulatory control of practices. It also discusses how exemptions and clearance is established and the scope of its applications for regulatory control. The concept of general clearance levels for any type of material and any possible pathway of disposal is also introduced in this work. Guidance of the Group of Experts establishing scenarios for general clearance, parameter values, and a nuclide-specific list of calculated clearance levels is also presented. Regulatory authorities are required to develop guidance on exemption and clearance levels to assist licensees and registrants to know which practices and sources within practices are exempted from regulatory control and those to be cleared from further controls. Exemption and clearance levels are tools for assisting the Regulatory Authority to optimize the use of resources. (author)

Hypertension is an emerging public health problem in Sub Saharan Africa (SSA) and urbanization is considered to favor its emergence. Given a paucity of information on hypertension and associated risk factors among urban slum dwellers in SSA, we aimed to characterize the distribution of risk factors for hypertension and investigate their association with hypertension in an urban slum in Kenya. We conducted a community based cross-sectional survey among adults 35 years and older living in Kibera slum Nairobi, Kenya. Trained interviewers collected data on socio demographic characteristics and self reported health behaviours using modified World Health Organization stepwise surveillance questionnaire for chronic disease risk factors. Anthropometric and blood pressure measurements were performed following standard procedures. Multiple logistic regression was used for analysis and odds ratios with 95 % confidence intervals were calculated to identify risk factors associated with hypertension. A total of 1528 adults were surveyed with a mean age of 46.7 years. The age-standardized prevalence of hypertension was 29.4 % (95 % CI 27.0-31.7). Among the 418 participants classified as hypertensive, over one third (39.0 %) were unaware they had hypertension. Prevalence of current smoking and alcohol consumption was 8.5 and 13.1 % respectively. Over one quarter 26.2 % participants were classified as overweight (Body Mass Index [BMI] ≥25 to ≤29.9 kg/m(2)), and 17 % classified as obese (BMI ≥30 kg/m(2)). Overweight, obesity, current smoking, some level of education, highest wealth index, moderate physical activity, older age and being widowed were each independently associated with hypertension. When fit in a multivariable logistic regression model, being a widow [AOR = 1.7; (95 % CI, 1.1-2.6)], belonging to the highest wealth index [AOR = 1.6; (95 % CI, 1.1-2.5)], obesity [AOR = 1.8; 95 % CI, 1.1-3.1)] and moderate physical activity [AOR = 1.9; (95 % CI

2010-07-01

Full Text Available Bangladesh has one of the highest maternal mortality rates (MMR in the world. The estimated lifetime risk of dying from pregnancy and childbirth related causes in Bangladesh is about 100 times higher compare to developed countries. However, utilization of maternal health care services (MHCS is notably low. This study examines the socio-economic determinants of utilization of MHCS in some slum areas of Dhaka city. The overall utilization was 86.3% of women; however, utilization of different sorts of MHCS was very low, i.e., the mean utilization was found to be 2.25 out of 5 MHCS. Indicator wise, ANC, TT, institutional delivery, delivery assistance by health professional and PNC were received by 61.3%, 80.4%, 12.6%, 33.2% and 55.4% of women respectively. Variation was observed with different socio-economic variables. Multiple regression model could explain 38% of variance (P<0.001. Among the significant determinants, order of last birth negatively explained the most variance (15.2%. Similarly, distance between home and clinic was found to affect the utilization negatively. Besides, some respondents’ socio economic variables had a significant positive effect on MHCS utilization. To reduce maternal mortality in disadvantaged women in slum areas, this study might suggest a few pointers while considering formulation of policies and planning. Ibrahim Med. Coll.

Full Text Available Abstract Background Malnutrition continues to be a critical public health problem in sub-Saharan Africa. For example, in East Africa, 48 % of children under-five are stunted while 36 % are underweight. Poor health and poor nutrition are now more a characteristic of children living in the urban areas than of children in the rural areas. This is because the protective mechanism offered by the urban advantage in the past; that is, the health benefits that historically accrued to residents of cities as compared to residents in rural settings is being eroded due to increasing proportion of urban residents living in slum settings. This study sought to determine effect of mother’s education on child nutritional status of children living in slum settings. Methods Data are from a maternal and child health project nested within the Nairobi Urban Health and Demographic Surveillance System (NUHDSS. The study involves 5156 children aged 0–42 months. Data on nutritional status used were collected between October 2009 and January 2010. We used binomial and multiple logistic regression to estimate the effect of education in the univariable and multivariable models respectively. Results Results show that close to 40 % of children in the study are stunted. Maternal education is a strong predictor of child stunting with some minimal attenuation of the association by other factors at maternal, household and community level. Other factors including at child level: child birth weight and gender; maternal level: marital status, parity, pregnancy intentions, and health seeking behaviour; and household level: social economic status are also independently significantly associated with stunting. Conclusion Overall, mothers’ education persists as a strong predictor of child’s nutritional status in urban slum settings, even after controlling for other factors. Given that stunting is a strong predictor of human capital, emphasis on girl-child education may

Clearance Laboratory - Capability and measurement sensitivity

2005-08-01

A new low-level Clearance Laboratory has been built at the Risoe-site. Building materials with a low content of naturally occurring radionuclides have been used. To minimize transport of radon gas from soil into the laboratory the foundation has been supplied with a membrane. The laboratory has been equipped with two high-efficiency germanium detectors. These detectors will be used for clearance measurements on the predicted amount of 15,000 - 18,000 tonnes of non-active or nearly non-active materials, which will originate from the decommissioning of all the nuclear facilities at the Risoe-site. They will be used also for clearance measurements on buildings and land. Objects and materials to be measured for clearance are placed on a rotation table that can carry up to one tonne and can rotate once a minute to simulate some averaging of inhomogeneously distributed activity. Sensitivity and background measurements reveal that measuring times of 20 - 50 minutes would normally be sufficient to detect radionuclide concentrations of only a small fraction of the nuclide-specific clearance levels with a sufficiently low uncertainty. Probability calculations of the measurement capacity of the Clearance Laboratory indicate that the mean value of the total measuring time for all materials that potentially can be cleared would be 13 years with a 95% probability of being less than 25 years. The mean value of the annual amount of materials that can be measured in the laboratory is 600 tonnes with a 95% probability of being less than 1,200 tonnes. If needed, there is room for additional measuring systems to increase the capacity of the laboratory. (au)

Experience and lessons learnt from clearance in Germany

International Nuclear Information System (INIS)

Thierfeldt, Stefan

2002-01-01

Clearance is an important corner-stone of waste management in nuclear installations in Germany. It has been practised successfully for around two decades. The importance of clearance can also be judged from the fact that it has been included detailedly in the new German Radiation Protection Ordinance. Currently, there are 19 NPPs and a number of fuel cycle installations in operation in Germany. The main waste quantities, however, arise from the dismantling of NPPs and fuel cycle installations which are currently in decommissioning. As most of the decommissioning projects are targeted for early dismantling instead of safe enclosure, there is already considerable experience with the application of clearance procedures and verification of clearance levels. The German waste management strategy is governed by two options: Clearance of the material (after decontamination and release measurement). After clearance, the material is no longer regarded as radioactive in a legal sense. Final disposal of the material as radioactive waste in a deep geological repository (no near-surface disposal facilities exist or are planned in Germany). A deep geological repository is planned to be operable around 2030. Stefan Thierfeldt described German clearance requirements and lessons learned from their application to decommissioning of power reactors. The great majority of the waste was in fact recycled, although the costs were dominated by the small fraction that had to be disposed of as radioactive waste. Among the lessons learned from the German experience were some revealing insights into the public perception of both clearance and of recycling of material from decommissioning of a nuclear installation

Order of magnitude and standard deviation of 99m Tc-DTPA and 131 I-hippurate slope clearance were analyzed successively in 56 male Wistar rats. The clearance of 99m Tc-DTPA was 17.4 ± 3.43 μl · s -1 (100 g b-w) -1 , of 131 I-hippurate 34.3 ± 7.21 μl · s -1 (100 g b-w) -1 . In 17 rats inulin and PAH clearances were analyzed by steady state method with permanent infusion and 3 to 4 urine collection periods 3 days later. The endogeneous creatinine clearance was determined within the same periods. The 99m Tc-DTPA slope clearance corresponded to the inulin clearance, as well as the hippurate clearance to the PAH clearance. The high filtration fraction calculated from nuclear medicine and chemical clearance methods and the low PAH extraction (42%) let suggest that PAH and hippurate are eliminated only incompletely from plasma in rat kidney and are unsuitable for determination of renal blood supply in rats. The creatinine clearance with 4.7 ± 1.38 μl · s -1 (100 g b-w) -1 was far beneath the clearance of inulin and 99m Tc-DTPA, supposing that creatinine is reabsorbed tubularly in part and the creatinine clearance can not be used for valuation of the GFR in rats. However, for this the 99m Tc-DTPA clearance in Wistar rats seems to be well suited. (author)

Five outbreaks of ebola occurred in Uganda between 2000-2012. The outbreaks were quickly contained in rural areas. However, the Gulu outbreak in 2000 was the largest and complex due to insurgency. It invaded Gulu municipality and the slum- like camps of the internally displaced persons (IDPs). The Bundigugyo district outbreak followed but was detected late as a new virus. The subsequent outbreaks in the districts of Luwero district (2011, 2012) and Kibaale (2012) were limited to rural areas. Detailed records of the outbreak presentation, cases, and outcomes were reviewed and analyzed. Each outbreak was described and the outcomes examined for the different scenarios. Early detection and action provided the best outcomes and results. The ideal scenario occurred in the Luwero outbreak during which only a single case was observed. Rural outbreaks were easier to contain. The community imposed quarantine prevented the spread of ebola following introduction into Masindi district. The outbreak was confined to the extended family of the index case and only one case developed in the general population. However, the outbreak invasion of the town slum areas escalated the spread of infection in Gulu municipality. Community mobilization and leadership was vital in supporting early case detection and isolations well as contact tracing and public education. Palliative care improved survival. Focusing on treatment and not just quarantine should be emphasized as it also enhanced public trust and health seeking behavior. Early detection and action provided the best scenario for outbreak containment. Community mobilization and leadership was vital in supporting outbreak control. International collaboration was essential in supporting and augmenting the national efforts.

Accumulation of toxic protein aggregates—amyloid-β (Aβ) plaques and hyperphosphorylated tau tangles—is the pathological hallmark of Alzheimer disease (AD). Aβ accumulation has been hypothesized to result from an imbalance between Aβ production and clearance; indeed, Aβ clearance seems to be impaired in both early and late forms of AD. To develop efficient strategies to slow down or halt AD, it is critical to understand how Aβ is cleared from the brain. Extracellular Aβ deposits can be removed from the brain by various clearance systems, most importantly, transport across the blood–brain barrier. Findings from the past few years suggest that astroglial-mediated interstitial fluid (ISF) bulk flow, known as the glymphatic system, might contribute to a larger portion of extracellular Aβ (eAβ) clearance than previously thought. The meningeal lymphatic vessels, discovered in 2015, might provide another clearance route. Because these clearance systems act together to drive eAβ from the brain, any alteration to their function could contribute to AD. An understanding of Aβ clearance might provide strategies to reduce excess Aβ deposits and delay, or even prevent, disease onset. In this Review, we describe the clearance systems of the brain as they relate to proteins implicated in AD pathology, with the main focus on Aβ. PMID:26195256

Sanitation is one of the most intimate issues that affect women, especially in slums of developing countries. There are few studies that have paid attention to the gender variations in access, choice to use and cleaning of shared latrines in slums. This paper draws on qualitative data from a cross sectional study conducted between 2012 and 2013 in six slums of Kampala City, Uganda. The study involved both women and men. Data were collected from 12 Focus Group Discussions (FGDs), 15 Key informant interviews; community transects and photographs of shared latrines. Location of a shared latrine facility, distance, filthy, narrow and irregular paths; the time when a facility is visited (day or night), privacy and steep inclines were gender 'filters' to accessing shared latrines. A full latrine pit was more likely to inhibit access to and choice of a facility for women than men. Results indicate that the available coping mechanisms turned out to be gendered, with fewer options available for women than men. On the whole, women sought for privacy, easy reach, self-respect and esteem, cleanliness and privacy than men. While men like women also wanted clean facilities for use; they (men) were not keen on cleaning these facilities. The cleaning of shared latrines was seen by both women and men as a role for women. The presence of sanitation facilities as the first step in the access, choice, use, and cleaning by both women and men has distinct motivations and limitations along gender lines. The study confirms that the use and cleaning of latrines is regulated by gender in daily living. Using a latrine for women was much more than relieving oneself: it involved security, intimacy and health concerns.

Secretin enhances [14C]erythritol clearance in unanesthetized dogs

To determine the effect of secretin infusion on clearance of inert markers into bile, unanesthetized dogs fitted with Thomas cannulas received continuous infusions of [ 14 C]erythritol and [ 3 H]inulin throughout study. Taurocholic acid administered sequentially at 9.0, 20.0, and 40.0 mumol/min enhanced [ 14 C]erythritol clearance, and GIH secretin (3 units/min) administered along with TCA (40.0 mumol/min) increased [ 14 C]erythritol clearance from 4.9 +/- 1.2 ml/10 min to 6.8 +/- 1.3 ml/10 min (P less than 0.001), but simultaneously measured [ 3 H]inulin clearance was unaltered. Secretin alone also increased [ 14 C]erythritol clearance but did not alter [ 3 H]inulin clearance. The increase in [ 14 C]erythritol clearance per unit increase in bile flow was less during secretin infusion than TCA. Thus, secretin increases [ 14 C]erythritol transport through restricted channels, probably distal to the canaliculi. [ 14 C]Erythritol may not be an accurate marker for canalicular bile flow in dogs during secretin infusion

Urban populations now exceed rural populations worldwide, creating unique challenges in providing basic services, especially in developing countries where informal or illegal settlements grow in peri-urban areas. West Africa is an acute example of the problems created by rapid urban growth, with high levels of urban poverty and low water and sanitation access rates. Although considerable effort has been made in providing improved water access and urban services to slum communities, research indicates that clean water access rates are not keeping up with urbanization rates in several areas of the world and that rapidly growing slum communities are beginning to overwhelm many prior water improvements projects. In the face of these challenges, domestic rainwater harvesting is proposed as a technologically appropriate and economically viable option for enhancing water supplies to urban slum households. However, assessing the reliability, potential health impacts, and overall cost-effectiveness of these systems on a regional level is difficult for several reasons. First, long daily rainfall records are not readily available in much of the developing world, including many regions of sub-Saharan Africa. Second, significant uncertainties exist in the relevant cost, water use, and health data. Third, to estimate the potential future impacts at the regional scale, various global change scenarios should be investigated. Finally, in addition to these technical challenges, there is also a need to develop relatively simple and transparent assessment methods for informing policy makers. A procedure is presented for assessment of domestic rainwater harvesting systems using a combination of scenario, sensitivity, and trade-off analyses. Using data from West Africa, simple stochastic weather models are developed to generate rainfall sequences for the region, which are then used to estimate the reliability of providing a range of per capita water supplies. Next, a procedure is

Averages and standard deviations of 99m Tc-DTPA and 131 I-hippurate slope clearance were consecutively determined for 56 male Wistar rats, with a body-weight of 271 ± 69 g in a single investigation. Clearance of 99m Tc-DTPA was 17.4 ± 3.4, that of 131 I-hippurate was 34.3 ± 7.2 μl · s -1 per 100 g body weight. For 17 rats inulin and PAH clearances were determined after 3 days with the steady-state method with continuous infusion and 3-4 periods of urine collection. During the same periods endogeneous creatinine clearance was determined. 99m Tc-DTPA slope clearance correlated well with inulin clearance, also the hippurate with the PAH clearance. The high values of the filtration fraction, calculated from radioisotope and chemical methods, and the low PAH extraction of 42% lead to the conclusion, that PAH and hippurate are incompletely eliminated by the rat kidney from plasma and therefore are inadequate for determining renal blood flow in rats. Creatinine clearance was 4.7 ± 1.38 μl · s -1 per 100 g body weight, much lower than that of inulin and 99m Tc-DTPA. Therefore is assumed, that tubular reabsorption of creatinine occurs and creatinine clearance cannot serve for the evaluation of GFR in rats. For this, however, the clearance of 99m Tc-DTPA seems well applicable in Wistar rats. (author)

Metabolic clearance rate and urinary clearance of purified beta-core

Wehmann, R.E.; Blithe, D.L.; Flack, M.R.; Nisula, B.C.

1989-01-01

We injected a highly purified preparation of the beta-core molecule, a fragment of hCG beta excreted in pregnancy urine, into five men and three women to determine its kinetic parameters, MCR, and urinary clearance. The beta-core molecule was distributed in an initial volume [1950 +/- 156 (mean +/- SEM) mL/m2 body surface area] approximately equal to the estimated plasma volume. Its disappearance was multiexponential on a semilogarithmic plot, with a rapid phase t1/2 of 3.5 +/- 0.7 min and a slow phase t1/2 of 22.4 +/- 4.2 min. The transit time (the mean time spent by a molecule of beta-core in transit) was 20.6 +/- 2.1 min. The MCR was 192.0 +/- 8.0 mL/min.m2 body surface area. About 5% of the injected dose of beta-core was excreted into the urine in the first 30 min after injection, and low levels of excretion persisted for up to 7 days. The urinary clearance rate of beta-core was 13.7 +/- 1.4 mL/min.m2, accounting for about 8% of the elimination of beta-core from the plasma. The beta-core immunoreactivity in serum and urine was characterized by gel filtration and three independent RIA systems to show that its properties were indistinguishable from those of the injected beta-core. Serum levels of beta-core in pregnant women were less than 0.2 ng/mL, while the amounts excreted in their urine were as much as 5 mg/day. Based on these clearance parameters of beta-core in normal subjects, less than 0.2% of the beta-core excreted in pregnancy urine is derived by urinary clearance of plasma beta-core. Therefore, more than 99% of the beta-core excreted in pregnancy urine is derived from beta-core in a compartment separate from plasma. In particular, these data indicate that there is relatively little placental secretion of beta-core into plasma and that placental secretion does not account for the vast majority of beta-core in pregnancy urine

Full Text Available Diarrhea remains a major health issue in developing countries, with high morbidity and mortality rates. Determining the incidence of acute diarrhea in children and its associated factors is crucial to the planning of preventive approaches. The objective of this study was to determine the incidence of diarrhea and to assess some relevant associated factors to it in children younger than 40 months living in two slums of Salvador, Brazil. This is the first prospective cohort, community-based study that was performed in two periurban slums of Salvador, Brazil. Eighty-four children younger than 40 months were randomly selected and visited every other day for one year. The chi-square test was used to evaluate the occurrence of diarrhea and its associated factors. During the surveillance period, 232 diarrhea episodes were identified, resulting in an incidence rate of 2.8 episodes/child/year. In average (mean value of 84 children,each child suffered 11.1 days of diarrhea per year, yielding an average duration of 3.9 days per episode. The highest incidence rates were found among children under one year old. Early weaning, male sex, malnutrition, having a mother younger than 25 years or who considered her child malnourished, missed immunizations and previous pneumonia were associated factors for suffering diarrheal episodes. The rates of incidence and duration of diarrhea that we found are in accordance to those reported by others. Additionally, our results reinforce the importance of environmental and health-related associated factors to the onset of diarrhea.

Environmental impacts of wastewater from urban slums: case study - Old Fadama, Accra

Full Text Available The burgeoning of slums in the developing world poses an urgent environmental threat due to insanitary conditions and rampant disposal of wastewater. To assess the potential environmental impacts, domestic wastewater from Ghana's biggest urban slum - Old Fadama was characterised throughout the dry and wet seasons. The study drew on a comprehensive assessment of the general sanitary conditions in the community to determine the sources of pollution and water quality monitoring. BOD5 levels of wastewater from the study area were 545.63±99.88mg/L and 645.94±331.43mg/L in the dry and wet seasons respectively whereas COD levels were 1100.45±167.16mg/L and 1415.12±722.83mg/L in the dry and wet seasons respectively. E-coli levels were 4±1x106CFU/100mL and 4200±2400 x106CFU/100mL in the dry and wet seasons respectively whereas total coliform levels also showed the same trend with 9±2106CFU/100mL and 16800±5100106CFU/100mL in the dry and wet seasons respectively. The study identifies that wastewater from this community has potential deleterious environmental implications due to high levels of nutrients, oxygen-demanding substances and faecal coliforms. Pollutants were identified to be emanating predominantly from open defecation and indiscriminate waste disposal. Efforts should thus be directed towards improving sanitary conditions viz. access to toilet facilities, waste disposal mechanisms and best management practices for wastewater.

Domestic violence (DV) is prevalent in low-income and slum-dwelling communities in India. To date, the focus of DV prevention in resource-poor settings has largely been with women. We herein aim to identify correlates of DV perpetration to help inform future primary prevention efforts that focus on behavioral change in men. Utilizing a cross-sectional design, potential correlates of DV perpetration were explored among a geographically-clustered random sample of 100 recently-married men residing in slums in Pune, India. In multivariable regression, DV perpetration was associated with less time spent alone in the relationship post-marriage (standardized β = -0.230, p<0.01), not attaining the "husband ideal" (standardized β = -0.201, p<0.05), poor resilience (standardized β = -0.304, p < .01), having limited definitions of behaviors constituting DV (standardized β = -0.217, p<0.05), and reporting greater jealousy if the participant's spouse were to talk to men outside the family (standardized β = 0.272, p<0.01). The identified correlates should inform components of future DV primary prevention interventions that target men as potential perpetrators or the couple as a unit.

The investigation of interspecies differences in bisphenol A (BPA) pharmacokinetics (PK) may be useful for translating findings from animal studies to humans, identifying major processes involved in BPA clearance mechanisms, and predicting BPA PK parameters in man. For the first time, a large range of species in terms of body weight, from 0.02 kg (mice) to 495 kg (horses) was used to predict BPA clearance in man by an allometric approach. BPA PK was evaluated after intravenous administration of BPA in horses, sheep, pigs, dogs, rats and mice. A non-compartmental analysis was used to estimate plasma clearance and steady state volume of distribution and predict BPA PK parameters in humans from allometric scaling. In all the species investigated, BPA plasma clearance was high and of the same order of magnitude as their respective hepatic blood flow. By an allometric scaling, the human clearance was estimated to be 1.79 L/min (equivalent to 25.6 mL/kg.min) with a 95% prediction interval of 0.36 to 8.83 L/min. Our results support the hypothesis that there are highly efficient and hepatic mechanisms of BPA clearance in man. - Highlights: • Allometric scaling was used to predict BPA pharmacokinetic parameters in humans. • In all species, BPA plasma clearance approached hepatic blood flow. • Human BPA clearance was estimated to be 1.79 L/min

The high risk of experiencing domestic violence (DV) among married women in India who reside in slum communities underscores the need for effective, evidence-based, and culturally-tailored primary prevention. To inform such DV primary prevention strategies for this population, we herein aimed to identify correlates of DV experience in early marriage. Utilizing a cross-sectional design, potential correlates of DV experience were explored among a geographically-clustered random sample of 100 recently-married women residing in slums in Pune, India. In multivariable regression, DV experience was associated with less educational attainment by the participant's spouse (standardized β = -0.281, p = 0.004), less satisfaction of the spouse's family with the maanpaan (wedding-related gifts provided by the bride's family) they received at the time of marriage (standardized β = -0.298, p<0.001), poorer conflict negotiation skills (standardized β = -0.308, p<0.001), and greater acknowledgement of DV occurrence in family and friends (standardized β = 0.436, p<0.001). These correlates suggest strategies that could be incorporated into future DV primary prevention interventions for this vulnerable population (i.e. promoting completion of formal education of boys alongside girls, mitigating causes of familial dowry harassment, improving conflict negotiation skills, and challenging norms surrounding DV).

Full Text Available Background:Marriages and having children is a universal phenomenon in India and in slum areas of cities there is a tendency to have more number of children in married women due to many interrelated causes. In the current study we have tried to explore some of the reasons for having more number of children in urban slum area. Objective: To study the effect of education,age at marriage of women and socioeconomic status of the family onnumber of children among married women of reproductive age group in a slum area of Mumbai. Materials and Methods: A cross sectional observational study was carried out in the field practice area of an Urban Health Training Centre of a teaching hospital in Mumbai. Results:A sample of 342 women was taken by random sampling. Questionnaire was administered in the local language.It was found that illiteracy, marriage before 18 years of age and low socioeconomic status,are significantly associated with more than 3living children.Out of these, socioeconomic status of the family had the greatest influence on bearing of the total number of children, followed by the age of women at marriage and then educational status of the women. Conclusion:Improvement in education, socioeconomic status and increasing the age at marriage can prove to be very effective for the control of population.

The authors have evaluated iohexol as a filtration marker in 150 children. The clearance of iohexol was compared with that of inulin or with a formula clearance. The single-sample clearance of iohexol showed a good correlation with the clearance of inulin. The clearance of iohexol correlated well with the formula clearance. The optimal blood sampling time for iohexol clearance determinations appears to be between 120 and 180 min after injection, at least in patient with relatively normal filtration rates. It is concluded that iohexol clearance is an accurate method of determining the glomerular filtration rate in clinical practice. 25 refs., 5 figs

Compressors consume a considerable portion of the electricity used in the industrial sector. Hence, improvements in compressor efficiency lead to energy savings and reduce environmental impacts. The efficiency of an unshrouded centrifugal compressor suffers from leakage flow over the blade tips. The effect of tip leakage flow on the passage flow differs between the full and splitter blade passages. In this study, the differences in the flow fields between the full and splitter blade passages were studied numerically in detail. An industrial high-speed compressor with a design pressure ratio of 1.78 was modelled. Numerical studies were conducted with six different tip clearances and three different diffuser widths. The results show that increasing tip clearance considerably increases the reversed flow into the impeller with an unpinched diffuser. The reversed flow then partly mixes into the flow in the same blade passage it entered the impeller and the rest migrates over the blade, mixing with the tip clearance flow. Furthermore, as the reversed and clearance flow mix into the wake, the wake is weakened. As pinch reduces both the reversed flow and clearance flow, the passage wakes are stronger with pinches. However, the pinch is beneficial as the losses at the impeller outlet decrease.

Hepatic drug clearance following traumatic injury.

Science.gov (United States)

Slaughter, R L; Hassett, J M

1985-11-01

Trauma is a complex disease state associated with physiologic changes that have the potential to alter hepatic drug clearance mechanisms. These responses include alterations in hepatic blood flow, reduction in hepatic microsomal activity, reduction in hepatic excretion processes, and changes in protein binding. Hepatic blood flow is influenced by sympathomimetic activity. Both animal and human studies demonstrate an initial reduction and subsequent increase in hepatic blood flow, which coincides with an observed increase and subsequent return to normal in serum catecholamine concentrations. Unfortunately, there are no human studies that address the importance these findings may have to the clearance processes of high intrinsic clearance compounds. Animal studies of trauma indicate that hepatic microsomal activity is depressed during the post-traumatic period. Reduction in the hepatic clearance of antipyrine, a model low intrinsic compound, has also been demonstrated in animal models of trauma. In addition to these effects, hepatic excretion of substances such as indocyanine green and bilirubin have been demonstrated to be impaired in both traumatized animals and humans. Finally, substantial increases in the serum concentration of the binding protein alpha 1-acid glycoprotein occur in trauma patients. This has been reported to be associated with subsequent decreases in the free fraction of lidocaine and quinidine. In addition to changing serum drug concentration/response relationships, the pharmacokinetic behavior of drugs bound to alpha 1-acid glycoprotein should also change. Preliminary observations in our laboratory in a dog model of surgically-induced trauma have shown a reduction in the total clearance of lidocaine and reduction in free lidocaine concentration.(ABSTRACT TRUNCATED AT 250 WORDS)

Evidence supporting the hypothesis that reduced cerebrospinal fluid (CSF) clearance is involved in the pathophysiology of Alzheimer disease (AD) comes primarily from rodent models. However, unlike rodents, in which predominant extracranial CSF egress is via olfactory nerves traversing the cribriform plate, human CSF clearance pathways are not well characterized. Dynamic PET with 18 F-THK5117, a tracer for tau pathology, was used to estimate the ventricular CSF time-activity as a biomarker for CSF clearance. We tested 3 hypotheses: extracranial CSF is detected at the superior turbinates; CSF clearance is reduced in AD; and CSF clearance is inversely associated with amyloid deposition. Methods: Fifteen subjects, 8 with AD and 7 normal control volunteers, were examined with 18 F-THK5117. Ten subjects additionally underwent 11 C-Pittsburgh compound B ( 11 C-PiB) PET scanning, and 8 were 11 C-PiB-positive. Ventricular time-activity curves of 18 F-THK5117 were used to identify highly correlated time-activity curves from extracranial voxels. Results: For all subjects, the greatest density of CSF-positive extracranial voxels was in the nasal turbinates. Tracer concentration analyses validated the superior nasal turbinate CSF signal intensity. AD patients showed ventricular tracer clearance reduced by 23% and 66% fewer superior turbinate CSF egress sites. Ventricular CSF clearance was inversely associated with amyloid deposition. Conclusion: The human nasal turbinate is part of the CSF clearance system. Lateral ventricle and superior nasal turbinate CSF clearance abnormalities are found in AD. Ventricular CSF clearance reductions are associated with increased brain amyloid depositions. These data suggest that PET-measured CSF clearance is a biomarker of potential interest in AD and other neurodegenerative diseases. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

Analysis of conservativity analysis for clearance levels. Final report

International Nuclear Information System (INIS)

Deckert, A.; Thierfeldt, S.

1997-07-01

When deriving clearance levels for material from nuclear installations it is necessary to proceed with a certain degree of conservativity. This can, however, differ between various sets of clearance levels leading to inconsistencies between clearance pathways. The aim of the work therefore is to compare levels of conservativity for the following two sets of clearance levels: clearance levels for disposal as conventional waste and for metallic materials for recycling/reuse. A method was developed to quantify the degree of conservativity and make it comparable. The actual and future situation for disposal of (conventional) wastes in Germany was analysed. In addition, the masses, nuclide vectors, geographical distribution etc. for slightly radioactive material being cleared for conventional disposal was analysed and modelled and the resulting dose distributions were calculated. The values for the clearance levels were taken from the 1995 recommendation by the German Commission on Radiation Protection (SSK). By using realistic scenarios, the exposure was calculated for the personnel on the landfills and for persons of the general public being exposed via groundwater pathways. It could be shown that the trivial dose range will not be exceeded even if the masses of cleared material per landfill site exceed 100 Mg/a. Because of the types and distribution of nuclear installations in Germany and because of the nuclide vectors it is therefore not necessary to limit the masses per landfill sites. Clearance levels that are determined by the exposure pathways external exposure to and the inhalation of dust by the landfill personnel show a similar level of conservativity as those for metal scrap. This means that the clearance levels for gamma emitting nuclides are not overly restrictive. Although radiologically justified, raising the clearance levels would not lead to an increase of the material quantities because other nuclides of the respective nuclide vectors are limiting. In

In this paper, the flow field considering the hub clearance flow in a Kaplan turbine has been investigated through using the commercial CFD code ANSYS CFX based on high-quality structured grids generated by ANSYS ICEM CFD. The turbulence is simulated by k-ω based shear stress transport (SST) turbulence model together with automatic near wall treatments. Four kinds of simulations have been conducted for the runner geometry without hub clearance, with only the hub front clearance, with only the rear hub clearance, and with both front and rear clearance. The analysis of the obtained results is focused on the flow structure of the hub clearance flow, the effect on the turbine performance including hydraulic efficiency and cavitation performance, which can improve the understanding on the flow field in a Kaplan turbine.

In this paper, the flow field considering the hub clearance flow in a Kaplan turbine has been investigated through using the commercial CFD code ANSYS CFX based on high-quality structured grids generated by ANSYS ICEM CFD. The turbulence is simulated by k-ω based shear stress transport (SST) turbulence model together with automatic near wall treatments. Four kinds of simulations have been conducted for the runner geometry without hub clearance, with only the hub front clearance, with only the rear hub clearance, and with both front and rear clearance. The analysis of the obtained results is focused on the flow structure of the hub clearance flow, the effect on the turbine performance including hydraulic efficiency and cavitation performance, which can improve the understanding on the flow field in a Kaplan turbine.

In sub-Saharan Africa (SSA), rapid urbanization and changing lifestyle have modified the profile and pattern of various medical disorders. Apart from high prevalence rates, recent trends with regard to hypertension in Africa include: low levels of awareness, treatment and control. Although a large number of studies provide data about hypertension in SSA, few studies focused on special populations such as urban slum dwellers. The WHO STEP-wise approach to surveillance of noncommunicable diseases was used to access the prevalence of hypertension among adults in one of the urban slums in Enugu. Out of the 811 individuals aged 20 years and above surveyed, 774 (95.4%) cases were analyzed. About 4.7% and 2.7% reported a past history of diabetes and stroke, respectively, whereas 15% had a positive family history of hypertension. The mean (95% confidence interval (CI)) body mass index (BMI) was 23.7 (23.2-24.2) kg m(-2) among males and 26.6 (25.7-26.7) kg m(-2) among females (Pslums is very high and a cause for concern, and calls for urgent attention.

Determination of renal clearance of 131I-hippuran

International Nuclear Information System (INIS)

Ridzon, S.

1982-01-01

The author presents his own method for the determination of total renal clearance of 131 I-hippuran under conditions of its diminishing plasma concentration following single intravenous administration. Total renal clearance is determined as the ratio of the amount of activity excreted into the urine over a certain time interval and of the area limited by the curve of activity decrease in plasma and by the time axis in the corresponding interval. The results are demonstrated in five investigated healthy subjects, and very good agreement of the calculated values of total renal clearance for different time intervals in the same subject is pointed out. When isotope nephrography is simultaneously performed, the method allows to determine also the values of isolated renal clearance for each kidney separately. (author)

Inherited Disorders of Bilirubin Clearance

Science.gov (United States)

Memon, Naureen; Weinberger, Barry I; Hegyi, Thomas; Aleksunes, Lauren M

2016-01-01

Inherited disorders of hyperbilirubinemia may be caused by increased bilirubin production or decreased bilirubin clearance. Reduced hepatic bilirubin clearance can be due to defective 1) unconjugated bilirubin uptake and intrahepatic storage, 2) conjugation of glucuronic acid to bilirubin (e.g. Gilbert syndrome, Crigler-Najjar syndrome, Lucey-Driscoll syndrome, breast milk jaundice), 3) bilirubin excretion into bile (Dubin-Johnson syndrome), or 4) conjugated bilirubin re-uptake (Rotor syndrome). In this review, the molecular mechanisms and clinical manifestations of these conditions are described, as well as current approaches to diagnosis and therapy. PMID:26595536

Approaches towards establishing of clearance levels in Japan

Sumitani, N.; Watanabe, I.; Okoshi, M.

1998-01-01

It is important to establish necessary regulatory systems for decommissioning waste management, especially to establish clearance levels from regulatory control. To establish the regulatory systems, the Nuclear Safety Commission (NSC) has been discussing the unconditional clearance levels for materials from nuclear reactors since May 1997. The NSC tries to derive unconditional clearance levels for the materials such as concrete and ferrous metal, arising from nuclear reactor decommissioning. In the derivation, both disposal and recycle/reuse of the materials are considered. Typical scenarios and parameter values for dose estimation are selected considering the Japanese natural and social conditions. Preliminary clearance levels were derived from 10 μSv/yr of individual dose criterion and deterministic analysis. For most radionuclides, the preliminary results are the same order of magnitude recommended in IAEA-TECDOC-855. Some radionuclides such as β emitters, however, are different order of magnitude from those recommended in IAEA-TECDOC-855. It is necessary that international organizations lead the discussions on the clearance levels to conclude final consensus. (author)

Nuclear regulation. NRC's security clearance program can be strengthened

International Nuclear Information System (INIS)

Fultz, Keith O.; Kruslicky, Mary Ann; Bagnulo, John E.

1988-12-01

Because of the national security implications of its programs, the Nuclear Regulatory Commission (NRC) investigates the background of its employees and consultants as well as others to ensure that they are reliable and trustworthy. If the investigation indicates that an employee will not endanger national security, NRC grants a security clearance that allows access to classified information, material, and facilities. NRC also requires periodic checks for some clearance holders to ensure their continued clearance eligibility. The Chairman, Subcommittee on Environment, Energy, and Natural Resources, House Committee on Government Operations, asked GAO to review NRC's personnel security clearance program and assess the procedures that NRC uses to ensure that those who operate nuclear power plants do not pose a threat to the public. The Atomic Energy Act of 1954 requires NRC to conduct background investigations of its employees and consultants as well as others who have access to classified information, material, or facilities. To do this, NRC established a personnel security clearance program. Under NRC policies, a security clearance is granted after the Office of Personnel Management (OPM) or the Federal Bureau of Investigation checks the background of those applying for an NRC clearance. NRC also periodically reassesses the integrity of those holding the highest level clearance. NRC employees, consultants, contractors, and licensees as well as other federal employees hold approximately 10,600 NRC clearances. NRC does not grant clearances to commercial nuclear utility employees unless they require access to classified information or special nuclear material. However, the utilities have voluntarily established screening programs to ensure that their employees do not pose a threat to nuclear plants. NRC faces a dilemma when it hires new employees. Although its policy calls for new hires to be cleared before they start work, the security clearance process takes so long

A study for promoting measures of social acceptance on clearance system

International Nuclear Information System (INIS)

Okoshi, Minoru; Torii, Hiroyuki; Fujii, Yasuhiko

2007-01-01

Clearance is one of the useful concepts to manage large amounts of slightly contaminated solid radioactive materials generated from the decommissioning of nuclear facilities. Cleared materials are expected to be disposed of as conventional wastes or recycled to produce consumer goods. In Japan, the legal frame-work for clearance was established in 2005 by amending the Law to regulate nuclear materials, reactors and so on. However, it is not so clear whether the general public understands clearance well. In this paper, major concerns about clearance from the general public are analyzed based on the public comments for reports on clearance prepared by the Nuclear Safety Commission and the Nuclear Institute Safety Agency. The major anxieties for clearance expressed by the general public are the safety of clearance, unknown factors of radiation effects, possibilities of excess radiation exposure due to inadequate measurements of radioactivities and fairness in decision making. In order to deal with those anxieties, some countermeasures including the confidence in nuclear operators and regulatory authorities and controllability of clearance by the general public are discussed to promote the social acceptance of clearance by the general public.

2017-09-01

Full Text Available Diarrhea is a waterborne disease due to consumption of contaminated food/water. People in urban slum area have highest risk to get diarrhea because of poor hygiene and sanitation as well as limited access to uncontaminated water. This study aimed to identify conta­mination in watersources by Entamoeba Sp and helmint eggs (Anchylostoma duodenale, Ascaris lumbricoides, Trichuris trichuria in one of urban slum area in Bandung municipality. Samples were taken from 123 watersources (74 tap water, 21 borehole, 22 dugwell and 6 spring water which was randomly selected in 10 RW along the Cikapundung river basin in Tamansari subdistrict during period of July-September 2015. Water samples were examined by PCR to detect Entamoeba Sp and microscopic identification for helminth eggs. 90 out of 123 samples were positive for Entamoeba Sp (59 tap water, 16 dugwell, 11 borehole and 4 spring water. Helminth egg of Ascaris lumbricoides was detected from unimproved common dugwell which had very high risk of contamination. Appropriate of water treatment prior to consumption is vastly important. Physical improvement to construct improved dugwell should be done to prevent contamination from helminth eggs in watersources.

Intraarticular volume and clearance in human synovial effusions

International Nuclear Information System (INIS)

Wallis, W.J.; Simkin, P.A.; Nelp, W.B.; Foster, D.M.

1985-01-01

Intraarticular volumes were measured by radiolabeled albumin (RISA) distribution in chronic knee effusions from 11 rheumatoid arthritis patients and 9 osteoarthritis patients. Volumes of synovial fluid obtained at joint aspiration were substantially less than those found by RISA dilution. Up to 24 hours was needed for full distribution of RISA throughout the intraarticular compartment. Measured 123I and RISA radioactivity over the knee described monoexponential rate constants, lambda (minute-1). The clearance of 123I and RISA from synovial effusions was derived by the formulation volume (ml) X lambda (minute-1) = clearance (ml/minute). RISA clearance in rheumatoid effusions was significantly greater than that found in osteoarthritis effusions. Intraarticular volume and isotope clearance were easily quantified and provide measures for further evaluating the microvascular physiology of synovial effusions

Full Text Available Background: Studies assessing the prevalence of reproductive morbidity among males in India have chiefly focused on prevalence of Reproductive Tract Infections/Sexually Transmitted Infections (RTIs/STIs among males attending Sexually Transmitted Disease clinics, blood donors and other selected population groups, with only few focused on the magnitude and the type of reproductive morbidity amongst Indian males at community level. Objective: To estimate prevalence of reproductive morbidity including (RTIs/STIs among males in the age group of 20-50 years residing in an urban slum of Delhi. Methods: Out of 268 males in the targeted age group, selected by systematic random sampling, residing in an urban sum of Delhi, 260 males were subjected to clinical examination and laboratory investigations for diagnosis of reproductive morbidity. Laboratory investigations were done for diagnosis of Hepatitis B and C, Syphilis, Gonorrhoea, Non gonococcal urethritis and urinary tract infection. Results: A total of 90 (33.6% of 268 study subjects reported one or more perceived symptoms of reproductive tract / sexual morbidity in last six months. Overall reproductive morbidity based on clinical and laboratory diagnosis was present in 76 (29.2% study subjects and of this sexually acquired morbidity accounted for 21.2% cases. Hepatitis B was most common (10.3% reproductive morbidity followed by Urinary Tract Infection (5.0%, scabies (3.5% and congenital anomalies (3.5%. Conclusion: High prevalence of reproductive morbidity (29.2% amongst males in an urban slum highlights the need for more studies in different settings. There is a need for developing interventions in terms of early diagnosis and treatment and prevention.

To explore the context, experiences and pathways of seeking abortion care among married women in a minority dominated urban slum community in Mumbai city of India. A mixed-method study was conducted using a systematic random sampling method to select 282 respondents from the slum community. One fifth of these womenreported undergoing at least one induced abortion over past five years. A quantitative survey was conducted among these women (n = 57) using structured face-to-face interviews. Additionally, in-depths interviews involving 11 respondents, 2 community health workers and 2 key informants from the community were conducted for further exploration of qualitative data. The rate of induced abortion was 115.6 per 1000 pregnancies in the study area with an abortion ratio of 162.79 per 1000 live births. Frequent pregnancies with low birth spacing and abortions were reported among the women due to restricted contraception use based on religious beliefs. Limited supportfrom husband and family compelled the women to seek abortion services, mostly secretly, from private, unskilled providers and unregistered health facilities. Friends and neighbors were main sources of advice and link to abortion services. Lack of safe abortion facilities within accessible distance furtherintensifies the risk of unsafe abortions. Low contraception usage based on rigid cultural beliefs and scarcely accessible abortion services were the root causes of extensive unsafe abortions.Contraception awareness and counseling with involvement of influential community leaders as well as safe abortion services need to be strengthened to protect these deprived women from risks of unwanted pregnancies and unsafe abortions.

Water, Sanitation and Hygiene Situation in Kenya's Urban Slums.

Science.gov (United States)

Kamau, Njoroge; Njiru, Haron

2018-01-01

Kenya has undergone rapid urbanization as people migrate to the cities in search of economic opportunities. This has given rise to informal settlements characterized by overcrowding, poor infrastructure, and inadequate social amenities. A cross-sectional study on water, sanitation, and hygiene (WASH) status was carried out in Mathare, an informal settlement in Nairobi. A random sample of 380 households was used. The average household size was five people, and 26% of the household heads had completed secondary or higher level of education. The main source of income (70%) was self-employment with 41% of the households living on less than 1.5 USD per day. The WASH situation in the urban slums is below the minimum standard recommended by the World Health Organization (WHO). There is need to improve the situation by improving and installing basic infrastructure including water, sanitation, and solid waste collection.

Test Rig for Evaluating Active Turbine Blade Tip Clearance Control Concepts

Science.gov (United States)

Lattime, Scott B.; Steinetz, Bruce M.; Robbie, Malcolm G.

2003-01-01

Improved blade tip sealing in the high pressure compressor and high pressure turbine can provide dramatic improvements in specific fuel consumption, time-on-wing, compressor stall margin and engine efficiency as well as increased payload and mission range capabilities of both military and commercial gas turbine engines. The preliminary design of a mechanically actuated active clearance control (ACC) system for turbine blade tip clearance management is presented along with the design of a bench top test rig in which the system is to be evaluated. The ACC system utilizes mechanically actuated seal carrier segments and clearance measurement feedback to provide fast and precise active clearance control throughout engine operation. The purpose of this active clearance control system is to improve upon current case cooling methods. These systems have relatively slow response and do not use clearance measurement, thereby forcing cold build clearances to set the minimum clearances at extreme operating conditions (e.g., takeoff, re-burst) and not allowing cruise clearances to be minimized due to the possibility of throttle transients (e.g., step change in altitude). The active turbine blade tip clearance control system design presented herein will be evaluated to ensure that proper response and positional accuracy is achievable under simulated high-pressure turbine conditions. The test rig will simulate proper seal carrier pressure and temperature loading as well as the magnitudes and rates of blade tip clearance changes of an actual gas turbine engine. The results of these evaluations will be presented in future works.

The aim is to provide a summary of methods available for the assessment of tear turnover and tear clearance rates. The review defines tear clearance and tear turnover and describes their implication for ocular surface health. Additionally, it describes main types of techniques for measuring tear turnover, including fluorescein tear clearance tests, techniques utilizing electromagnetic spectrum and tracer molecule and novel experimental techniques utilizing optical coherence tomography and fluorescein profilometry. Areas covered: Internet databases (PubMed, Science Direct, Google Scholar) and most frequently cited references were used as a principal resource of information on tear turnover rate and tear clearance rate, presenting methodologies and equipment, as well as their definition and implications for the anterior eye surface health and function. Keywords used for data-search were as follows: tear turnover, tear clearance, fluorescein clearance, scintigraphy, fluorophotometry, tear flow, drainage, tear meniscus dynamics, Krehbiel flow and lacrimal functional unit. Expert commentary: After decades, the topic of tear turnover assessment has been reintroduced. Recently, new techniques have been developed to propose less invasive, less time consuming and simpler methodologies for the assessment of tear dynamics that have the potential to be utilized in clinical practice.

Durbolota (weakness), chinta rog (worry illness), and poverty: explanations of white discharge among married adolescent women in an urban slum in Dhaka, Bangladesh.

Science.gov (United States)

Rashid, Sabina Faiz

2007-03-01

I carried out ethnographic fieldwork among 153 married adolescent girls, aged 15-19, in a Dhaka slum from December 2001 to January 2003, including 50 in-depth interviews and eight case studies. I also held discussions with family and community members. In this article, I focus on popular understandings of vaginal discharge being caused by durbolota (weakness) and chinta rog (worry illness), as mentioned by young women. Eighty-eight young women reported that they had experienced white discharge, blaming it on a number of factors such as stress and financial hardships, tensions in the household, marital instability, hunger anxiety, and reproductive burdens. For married adolescent women in the urban slum, white discharge has many levels of meaning linked to the broader social, political, and material inequalities in their everyday lives.

Transactional sex has been associated with a high risk of HIV acquisition and unintended pregnancy among young women in urban slums in sub-Saharan Africa. However, few studies have explored the structural drivers of transactional sex from the perspective of both genders in these settings. This paper explores how young men and women understand the factors that lead to transactional sex among their peers, and how deprivation of material resources (housing, food and health care access) and consumerism (a desire for fashionable goods) may instigate transactional sex in the urban slums of Blantyre, Malawi. Data from 5 focus group discussions and 12 in-depth interviews undertaken with a total of 60 young men and women aged 18-23 years old, conducted between December 2012 and May 2013, were analysed using anticipated and grounded codes. Housing and food deprivation influenced decisions to engage in transactional sex for both young men and women. Poor health care access and a desire for fashionable goods (such as the latest hair or clothing styles and cellular phones) influenced the decisions of young women that led to transactional sex. Interventions that engage with deprivations and consumerism are essential to reducing sexual and reproductive health risks in urban slums.

Effect of clearance on cartilage tribology in hip hemi-arthroplasty.

Lizhang, Jia; Taylor, Simon D; Jin, Zhongmin; Fisher, John; Williams, Sophie

2013-12-01

Hemi-arthroplasty of the hip (an artificial femoral head articulating against the natural acetabulum) is used to treat fractured necks of femur; however, there is evidence that articulation causes erosion of the cartilage, resulting in pain for the patient. Parameters that may influence this cartilage erosion include head material and roughness, clearance between the head and acetabulum and activity levels of the patient. This study has assessed the effect of clearance of hemi-arthroplasty articulations on the contact stress, friction and cartilage deformation in an in vitro tribological simulation of the hemi-arthroplasty joint that applied dynamic loads and motion. It has been demonstrated that peak contact stress increased from 5.6 to 10.6 MPa as radial clearance increased from small (1.8 mm). In all samples, friction factor increased with time and was significantly less with extra-large clearances compared to small (<0.6 mm), medium (0.6-1.2 mm) and large (1.2-1.8 mm) clearances. The cartilage deformation observed was significantly greater in acetabulum samples paired to give small or extra-large clearances compared to those with medium or large clearances.

Full Text Available Introduction: Domestic Violence against women is still an unsolved issue in India, though, it is an important public health problem contributing to physical, mental illness and low quality of life. Aim: The study was undertaken with the aim to estimate the prevalence of domestic violence against ever married women in an urban slum and the associated factors contributing to it. Materials and Methods: A community-based cross-sectional study had been conducted among 430 ever married women of reproductive age group, selected using a systematic random sampling technique in an urban slum of Kolkata. Interviews were conducted using pre-designed, pre-tested semi structured schedule regarding their socio-demographic characteristics, violence experienced by the subjects in their lifetime, type of violence (physical, emotional and sexual violence and the person responsible for the same. Data were entered and analysed using SPSS 20.0 version. Results: The overall prevalence of any form of violence in the study population as a whole was (59.3%. The prevalence of physical, emotional, sexual violence was 61.6%, 84.3%and 58.8%, respectively. The occurrence of the event was reported by only 33.1% of the victims. Multivariate analysis revealed violence was higher among women belonging to families with low per capita income (6 years, low educational background of husband, not able to bear a male child, unemployment amongst both the spouses, leave the household on any pretext without prior permission from husband and where the wives did not attend household activities properly. Conclusion: The prevalence of domestic violence in urban slum of Kolkata was high which is an alarming public health problem which needs to be addressed at the earliest through awareness programmes and empowerment of women.

Clearances occur in almost all mechanical systems, typically such as the clearance between slide plate of gun barrel and guide. Therefore, to study the clearances of mechanisms can be very important to increase the working performance and lifetime of mechanisms. In this paper, rigid dynamic modelling of cantilever with clearance was done according to the subject investigated. In the rigid dynamic modelling, clearance is equivalent to the spring-dashpot model, the impact of beam and boundary face was also taken into consideration. In ADAMS software, the dynamic simulation was carried out according to the model above. The software simulated the movement of cantilever with clearance under external excitation. Research found: When the clearance is larger, the force of impact will become larger. In order to study how the stiffness of the cantilever's supporting part influences natural frequency of the system, A Euler beam which is restricted by a draught spring and a torsion spring at its end was raised. Through numerical calculation, the relationship between natural frequency and stiffness was found. When the value of the stiffness is close to the limit value, the corresponding boundary condition is illustrated. An ADAMS experiment was carried out to check the theory and the simulation.

Household and ambient air pollution are jointly responsible for about 7 million premature deaths annually. Women living in slums, with unhealthy environment, both indoors and outdoors, particularly those living close to industrial and/or vehicular pollution zones due to multiple sources of air pollution, are at the higher risk of having impaired lung function tests. The aim of this study was to estimate the prevalence of abnormal lung functions and to identify the environmental risk factors associated with them among adult women of 18-59 years. A total of 550 women aged 18-59 years were approached in a representative urban slum. Five hundred consented to participate and 299 had prebronchodilator spirometry satisfying ATS standards. House visits to assess environmental conditions were conducted to determine their association with forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC). Chi-square test was used to test the association of risk factors with lung functions. ANOVA was used to test the association of mean values of FEV1 and FVC with age. Out of 299 participants with acceptable spirometric curves, 5% had reduced FEV1/FVC ratio than the normal and 26.8% and 17.4% had lower values than predicted for FVC and FEV1, respectively. Altered lung function was related to age, tobacco smoking, and history of respiratory disease. Both ambient and household air pollution have a deleterious pulmonary effect on long-term women residents of a representative urban slum in Delhi.

International Nuclear Information System (INIS)

Holland, N. J.

1985-01-01

In a refrigeration system such as a split Stirling system, fluid seals associated with the reciprocating displacer are virtually dragless clearance seals. Movement of the displacer relative to the pressure variations in the working volume of gas is retarded by a discrete braking element. Because it is not necessary that the brake providing any sealing action, the brake can be designed for greater durability and less dependence on ambient and operating temperatures. Similarly, the clearance seal can be formed of elements having low thermal expansion such that the seal is not temperature dependent. In the primary embodiments the braking element is a split friction brake

The multi-clearances of breaking type steering trapezoidal mechanism joints influences vehicle steering stability. Hence, to ascertain the influence of clearance value on steering stability, this paper takes the steering mechanism of a certain vehicle type as a prototype that can be simplified into a planar six-bar linkage, then establishes the system dynamic differential equations after considering the two clearances of tie rods and the steering knuckle arms. The influence of the clearance parameters on the movement stability of the steering mechanism is studied using a numerical computation method. Results show that when the two clearances are equal, the planar movement of the tie rods changes from period-doubling to chaos as the clearances increase. When the two clearances are 0.25 mm and 1.5 mm respectively, the planar movements of the two side tie rods come into chaos, causing the steering stability to deteriorate. Moreover, with the increase of clearances, turning moment fluctuates more intensively and the peak value increases.

The third aim was to explore what factors contribute to differences among parents in how the...

Measurement with nasal scintigraphy of nasal mucociliary clearance in normal man

International Nuclear Information System (INIS)

Murai, Sumiko

1989-01-01

Nasal mucociliary function was evaluated by nasal scintigraphy in normal subjects. A microdrop of HSA or saline labelled with 99m Tc was dripped into the middle part of each middle meatus in the nasal cavity and its clearance was observed by scinticamera. The accumulated concentration of RI was determined every 30 seconds for 10 minutes. The changes of accumulated concentration were studied, and a curve of decreasing RI-counts was obtained, with the 'clearance rate' defined as 100% for the count at the initial 30 seconds and 'half time' as the time when radioactivity was reduced to one half the initial count. Nasal resistance was measured by rhinomanometry with the oscillation method. In nonsmokers, 10μl of saline was cleared (78.0±10.4%) significantly faster than 10μl of HSA (59.9±24.6%), and there was no significant difference in the clearance between 10μl and 5μl of HSA (55.9±27.7%). In smakers, the mucociliary clearance of 10μl of HSA and saline was significantly lower than in nonsmokers. The clearance of 10μl of HSA reflects a pathological state much better than that of 5μl. In nonsmokers, there is a significant negative correlation between nasal resistance and clearance rate, suggesting that the more patent the nose, the faster the mucociliary clearance. When both nostrils were closed, the clearance rate was significantly depressed. When one nostril was closed, there was no significant effect on clearance. Nasal resistance was decreased by exercise with a bicycle ergometer. Nasal mucociliary clearance was slightly decreased after exercise but not significantly so. (J.P.N.)

The role of clearance in Germany - release of materials, buildings and sites

International Nuclear Information System (INIS)

Thierfeldt, S.

2005-01-01

Clearance in Germany is far advanced. A complex regulatory framework exists in the Radiation Protection Ordinance (RPO/Strahlenschutzverordnung, StrlSchV) since 2001 which has replaced previous recommendations on clearance issued by the German Radiation Protection Commission (Strahlenschutzkommission, SSK). A number of options exist both for unconditional clearance (e.g. of all kinds of materials with no restrictions on the destination or future use) and for clearance for a specific purpose (e.g. recycling of metal scrap). For each clearance option there is a set of nuclide specific clearance levels which have been derived on the basis of the 10 Sv/a individual dose criterion using complex radiological models which are tailored to the respective material cycles (metal scrap, buildings, building rubble, waste for disposal, sites). The clearance levels have been thoroughly reviewed by the SSK. An extensive comparison to sets of clearance levels used in other countries or issued as guidance by international bodies revealed that the correspondence between values is between good and acceptable taking into account country-specific approaches and special assumptions which would not necessarily pertain to German situations. Clearance is a major factor in the material management, especially of nuclear installations undergoing decommissioning. The variety of clearance options leaves the operator of a nuclear installation sufficient flexibility for optimisation of the material management. Clearance is of particular importance in a country like Germany where the estimated costs for a future repository are very high and the interim storage facilities for radioactive material are limited and costly. While the licensee is responsible for his material management, the issuance of a clearance permit is done by the regulatory body upon application. The regulators may choose to use the clearance levels and regulations as stipulated by the RPO, or to impose site-specific regulations on

Whole body and regional clearances of noradrenaline and adrenaline in man

1984-01-01

the clearance values based on arterial and venous sampling averaged 1.4 and 2.5 l/min, respectively (p less than 0.02). The difference in clearance values was due to peripheral uptake of NA averaging 45%. The plasma appearance rate on NA averaged 2.4 nmol/min before surgery and it increased to 9.5 nmol...... we found no correlation between clearance values based on venous and arterial sampling. In other experiments we measured the influence of physical exercise in young healthy subjects on the clearance rate of plasma adrenaline (A). The clearance of A, which at rest averaged 1.9 l/min tended to increase...

Online monitoring of dynamic tip clearance of turbine blades in high temperature environments

Science.gov (United States)

Han, Yu; Zhong, Chong; Zhu, Xiaoliang; Zhe, Jiang

2018-04-01

Minimized tip clearance reduces the gas leakage over turbine blade tips and improves the thrust and efficiency of turbomachinery. An accurate tip clearance sensor, measuring the dynamic clearances between blade tips and the turbine case, is a critical component for tip clearance control. This paper presents a robust inductive tip clearance sensor capable of monitoring dynamic tip clearances of turbine machines in high-temperature environments and at high rotational speeds. The sensor can also self-sense the temperature at a blade tip in situ such that temperature effect on tip clearance measurement can be estimated and compensated. To evaluate the sensor’s performance, the sensor was tested for measuring the tip clearances of turbine blades under various working temperatures ranging from 700 K to 1300 K and at turbine rotational speeds ranging from 3000 to 10 000 rpm. The blade tip clearance was varied from 50 to 2000 µm. The experiment results proved that the sensor can accurately measure the blade tip clearances with a temporal resolution of 10 µm. The capability of accurately measuring the tip clearances at high temperatures (~1300 K) and high turbine rotation speeds (~30 000 rpm), along with its compact size, makes it promising for online monitoring and active control of blade tip clearances of high-temperature turbomachinery.

Background Aggregate urban health statistics mask inequalities. We described maternity care in vulnerable slum communities in Mumbai, and examined differences in care and outcomes between more and less deprived groups. Methods We collected information through a birth surveillance system covering a population of over 280 000 in 48 vulnerable slum localities. Resident women identified births in their own localities and mothers and families were interviewed at 6 weeks after delivery. We analysed data on 5687 births over one year to September 2006. Socioeconomic status was classified using quartiles of standardized asset scores. Results Women in higher socioeconomic quartile groups were less likely to have married and conceived in their teens (Odds ratio 0.74, 95% confidence interval 0.69–0.79, and 0.82, 0.78–0.87, respectively). There was a socioeconomic gradient away from public sector maternity care with increasing socioeconomic status (0.75, 0.70–0.79 for antenatal care and 0.66, 0.61–0.71 for institutional delivery). Women in the least poor group were five times less likely to deliver at home (0.17, 0.10–0.27) as women in the poorest group and about four times less likely to deliver in the public sector (0.27, 0.21–0.35). Rising socioeconomic status was associated with a lower prevalence of low birth weight (0.91, 0.85–0.97). Stillbirth rates did not vary, but neonatal mortality rates fell non-significantly as socioeconomic status increased (0.88, 0.71–1.08). Conclusion Analyses of this type have usually been applied across the population spectrum from richest to poorest, and we were struck by the regularly stepped picture of inequalities within the urban poor, a group that might inadvertently be considered relatively homogeneous. The poorest slum residents are more dependent upon public sector health care, but the regular progression towards the private sector raises questions about its quality and regulation. It also underlines the need for

Platelet microembolization may contribute to microcirculatory and organ damage following trauma and shock. It is hypothesized that posttraumatic reticuloendothelial depression predisposes to such microembolization by failure to clear altered platelets from the circulation. The present study evaluated the short-term (1 h) clearance and organ localization of radiolabeled homologous damaged platelets in normal rats and in rats following sublethal Noble-Collip drum trauma. Platelets were collected in citrated platelet-rich plasma from normal rats and labeled with 51Cr in citrated saline. Platelets were altered by repeated centrifugation in protein-free medium. These platelets differed functionally and morphologically from normal platelets. Disappearance of iv injected damaged platelets conformed to a two-compartment exponential clearance. Velocity of clearance in the rapid compartment correlated with hepatic platelet localization, whereas velocity of clearance in the second compartment correlated with splenic platelet localization. Clearance rate of the rapid compartment was depressed at 1 h after trauma and elevated at 24 h. These changes were associated with a decrease in hepatic platelet localization at 1 h and an increase above normal at 24 h. Splenic platelet localization was decreased by 3 h following trauma. Pulmonary platelet localization was increased at all times following trauma. It is concluded that the posttrauma state is associated with a defect in the reticuloendothelial system clearance of altered platelets, which may augment embolization of platelets in the lung.

The health and well-being of older people in Nairobi's slums

Directory of Open Access Journals (Sweden)

Catherine Kyobutungi

2010-09-01

Full Text Available Background: Globally, it is estimated that people aged 60 and over constitute more than 11% of the population, with the corresponding proportion in developing countries being 8%. Rapid urbanisation in sub-Saharan Africa (SSA, fuelled in part by rural–urban migration and a devastating HIV/AIDS epidemic, has altered the status of older people in many SSA societies. Few studies have, however, looked at the health of older people in SSA. This study aims to describe the health and well-being of older people in two Nairobi slums. Methods: Data were collected from residents of the areas covered by the Nairobi Urban Health and Demographic Surveillance System (NUHDSS aged 50 years and over by 1 October 2006. Health status was assessed using the short SAGE (Study on Global AGEing and Adult Health form. Mean WHO Quality of Life (WHOQoL and a composite health score were computed and binary variables generated using the median as the cut-off. Logistic regression was used to determine factors associated with poor quality of life (QoL and poor health status. Results: Out of 2,696 older people resident in the NUHDSS surveillance area during the study period, data were collected on 2,072. The majority of respondents were male, aged 50–60 years. The mean WHOQoL score was 71.3 (SD 6.7 and mean composite health score was 70.6 (SD 13.9. Males had significantly better QoL and health status than females and older respondents had worse outcomes than younger ones. Sex, age, education level and marital status were significantly associated with QoL, while slum of residence was significantly associated with health status. Conclusion: The study adds to the literature on health and well-being of older people in SSA, especially those in urban informal settlements. Further studies are needed to validate the methods used for assessing health status and to provide comparisons from other settings. Health and Demographic Surveillance Systems have the potential to conduct such

MENSTRUAL HYGIENE PRACTICES AND REPRODUCTIVE TRACT INFECTION AMONG SLUM DWELLING ADOLESCENT GIRLS AGED 15-19 YEARS OF DIBRUGARH TOWN, ASSAM

Directory of Open Access Journals (Sweden)

Pushpita Barman

2017-04-01

Full Text Available BACKGROUND Menstruation is a natural physiological process linked with several misconceptions and practices having crucial role for health and dignity of girls and women. Hygiene-related practices increases vulnerability to reproductive tract infections. Adolescent girls dwelling in slums are vulnerable to poor reproductive health due to lack of awareness about reproductive health. Keeping in view the above, study has been undertaken with the following aim and objective. The aim of the study is to assess the menstrual hygiene practices and reproductive tract infection among slum dwelling adolescent girls aged 15-19 years. MATERIALS AND METHODS A community-based cross-sectional study was conducted for 1 year from June 2014 to May 2015 covering 210 adolescent girls aged 15-19 years living in the slums of Dibrugarh Town, Assam. An interview using a predesigned and pretested format conducted by house to house survey. For analysis, mean, standard deviation and proportions were calculated, Chi-square and Fischer’s exact test was done to see the association. RESULTS Mean age of girls was (16.57 ± 1.48 years and mean age of menarche was (12.73 ± 1.44 years. Awareness about menstruation was 27.1% prior to attainment of menarche. Rate of sanitary napkins use was 68.6% and 53.2% girls cleaned external genitalia >2 times per day. Regarding cultural practices of restriction, 100% girls did not attend any religious occasions during menstruation. Prevalence of reproductive tract infection was 43.3%, which was significantly more among girls using homemade reusable pad and washing external genitalia ≤2 times per day during menstruation. CONCLUSION There is a need to improve menstrual hygiene practices amongst adolescent girls. Awareness building on menstrual hygiene and other factors like traditional beliefs and practices needs to be addressed.

Assessment of renal function with the Tc-99m-MAG3 clearance

International Nuclear Information System (INIS)

Keske, U.; Corcles, M.; Andreessen, R.; Wilfling, M.; Roll, D.; Gahl, G.; Felix, R.

1990-01-01

This paper evaluates the applicability of the 99m-Tc-mercaptoacetyle-triglycine (MAG3) clearance for the documentation of renal function. Renal clearance was measured with the method of Tauxe in 699 patients during routine renal scintigraphy with 80 MBq of 99mTc-MAG3. Serum creatinine level and MAG3 clearance show an inverse correlation. Patients with an elevated serum creatinine level constantly have a lowered MAG3 clearance and vice versa. For creatinine values lower than 1.8 mg/dL, minor changes in creatinine level are accompanied by large changes in MAG3 clearance. Age (in years) dependence of MAG3 clearance was evaluated in 487 patients who showed no evidence of impaired renal function

Effects of heart rate on myocardial thallium-201 uptake and clearance

International Nuclear Information System (INIS)

Nordrehaug, J.E.; Danielsen, R.; Vik-Mo, H.

1989-01-01

The effects of heart rate on the myocardial uptake and clearance of 201 Tl were studied prospectively in seven healthy men, mean age 43 +/- 7 (s.d.) yr. Initial and delayed (3 hr) thallium images were obtained in three views after three bicycle exercise tests: to maximal, 80% and 60% of predicted maximal heart rate. The mean of three views initial myocardial 201 Tl uptake was higher at maximal than at both 80% and 60% of predicted maximal heart rate, being 81% (p less than 0.01) and 60% (p less than 0.01) of maximal activity, respectively. The myocardial activity in the delayed images was identical. There was a linear relationship between heart rate and the initial myocardial activity, r = 0.86 (p less than 0.001). The mean (range) 201 Tl clearance was 58% (51-65), 47% (34-56), and 34% (22-49) (all differences p less than 0.01), respectively. Concordance among the three individual views in estimating clearance was best for the highest exercise level. There was a linear relationship between heart rate and clearance, r = 0.80 (p less than 0.001). Clearance was altered by only 1.67 x 10%/heart bpm (0.024 hr/heart beat). Clearance in the liver, spleen and lungs increased at submaximal exercise levels. Thus, a linear relationship between heart rate and clearance is the result of changes in the initial exercise myocardial 201 Tl activity. Submaximal exercise may reduce reproducibility of clearance estimation, and the change of myocardial clearance with heart rate seems less than previously suggested

Summary Obesity is associated with the metabolic syndrome. The aims were, first, to study the postprandial triglyceride clearance in young, healthy obese subjects and, second, to investigate if fasting triglycerides can predict delayed postprandial triglyceride clearance. Eighteen apparently healthy, obese subjects with no clinical signs of metabolic disturbances participated. Controls were age‐ and sex‐matched, healthy, normal weight subjects. Subclinical markers of metabolic disturbances were assessed by measuring postprandial triglycerides in serum and in chylomicrons by oral fat tolerance test. Postprandial triglyceride clearance for 8 h was assessed indirectly as removal of the lipid from serum during the oral fat tolerance test. Insulin resistance was measured by the homeostasis model assessment of insulin resistance (HOMA‐IR). Twelve (66%) of the apparently healthy obese individuals had insulin resistance measured by HOMA‐IR. There was a delayed clearance of serum triglycerides and chylomicron triglycerides at 6 h when compared with the control group, while, at 8 h, the differences were only detected for the chylomicron triglyceride clearance. Triglyceride response was significantly greater in the obese subjects. Fasting triglycerides in upper normal level predicted a delayed postprandial triglyceride clearance and insulin resistance. In young, apparently healthy obese subjects early metabolic disturbances including insulin resistance and delayed postprandial triglyceride clearance can be detected. Fasting serum triglyceride in upper normal level predicted delayed postprandial triglyceride clearance and insulin resistance. PMID:26469529

A virtual experimental modal analysis (VEMA) method is proposed to deal with the effects of joint clearance and link flexibility on the dynamic characteristics of the DSS in this paper. The focus is on the finite element modeling of the clearance joint, VEMA and the modal parameters identification of the DSS. The finite element models (FEM) of the clearance joint and the deployable structure are established in ANSYS. The transient dynamic analysis is conducted to provide the time history data of excitation and response for the VEMA. The fast Fourier transform (FFT) technique is used to transform the data from time domain to frequency domain. The frequency response function is calculated to identify the modal parameters of the deployable structure. Experimental verification is provided to indicate the VEMA method is both a cost and time efficient approach to obtain the dynamic characteristics of the DSS. Finally, we analyze the effects of clearance size and gravity on the dynamic characteristics of the DSS. The analysis results indicate that the joint clearance and gravity strongly influence the dynamic characteristics of the DSS.

Bangladesh's urban population is rising fast. In the capital, Dhaka, some 4 million people live in slums. They are lacking in wealth, power and social connections; probably under-counted in national surveys; and under-served by both government and non-government organisations, many of whom still see poverty as a rural issue or see the urban poor…

Applicability of Clearance Automatic Laser Inspection System to Clearance Measurement of Concrete Segments

International Nuclear Information System (INIS)

Sasaki, M.; Ogino, H.; Hattori, T.

2009-01-01

In the decommissioning of a nuclear power plant, large amounts of metal scrap and concrete segments require disposal when dismantling the nuclear reactor and surrounding facilities. When their activity level is negligible or sufficiently small, they can be regarded as general industrial waste. To distinguish between radioactive and nonradioactive materials, the clearance level for each radionuclide has been determined in units of activity concentration. These clearance levels are indicated in the International Atomic Energy Agency (IAEA) Safety Standards Series No. RS-G-1.7. The Japanese regulatory authority decided in 2005 to adopt the values given in RS-G-1.7 as clearance levels in legislation. Recently, a Clearance Automatic Laser Inspection System (CLALIS) has been developed utilizing gamma-ray measurement, automatic laser shape measurement and Monte Carlo calculation. CLALIS comprises four laser scanners and eight large plastic scintillation detectors surrounded by a 5-cm-thick lead shield. Using three-dimensional (3D) laser scanning, a measurement target, which is placed on the measuring tray, is represented as a dot image. The dot image is converted into voxels after noise removal, and is written in MCNP (A General Monte Carlo N-Particle Transport Code System) input files. When the gamma-ray measurement is carried out, the MCNP calculations are also carried out to obtain the calibration factor and background (BG) correction factors. For the clearance measurement of concrete segments, the effect of gamma-rays from natural radionuclides in the measurement target, such as K-40 and the radioactive decay products of Th-232 and U-238, should be taken into account to ensure adequate waste management. Since NE102A plastic scintillation detectors are used for gamma-ray measurement in CLALIS, it is impossible to distinguish between the count rates of natural radionuclides and contaminants on the basis of gamma-ray energy information. To overcome this problem, the

Clearance level and industrial waste management

International Nuclear Information System (INIS)

Asano, Toichi

1999-01-01

Defining the clearance level enables the radioactive waste with lower radioactivity than a certain level to be the general industrial waste and therefore consideration for public acceptance is essential. For this, it is necessary to understand laws concerning not only atomic power and radioactivity but also disposal and cleaning of general waste. It is also necessary that the waste below the clearance level should be as much as possible handled in the modern common concept of recycling of resources. In 1996, the weight of industrial waste was about 400 million tons, of which 40% was disposed by burning and dehydration, 39% was re-used and 21% was subjected to the final disposal like reclamation. Reduction, re-use and recycling of the generated waste are required for making the society with recycling of resources. Scrap concrete materials below the clearance level of 0.6 million tons are estimated to be generated by dismantling the light water reactor of 1 million kW output and profitable technology for recycling the scrap is under investigation.

Factors Associated with Spontaneous Clearance of Hepatitis C Virus in Chinese Population

Directory of Open Access Journals (Sweden)

Fei Kong

2014-01-01

Full Text Available Hepatitis C virus (HCV infections spontaneously clear in approximately 15–45% of infected individuals. Factors which influence spontaneous HCV clearance remain to be identified. The purpose of the present study was to identify variables associated with spontaneous HCV clearance in a referred population of Chinese patients. The prevalence of host, viral, and environmental factors known to influence the outcome of HCV infections was compared in 92 HCV spontaneous clearance subjects and 318 HCV persistent infection subjects. Univariate and multivariate analyses were performed to identify those factors associated with spontaneous HCV clearance. In univariate analysis, female gender, a history of icteric hepatitis, serologic evidence of concurrent HBV infection, and rs12979860 CC genotype were positively associated with spontaneous HCV clearance, while alcohol consumption was negatively associated with clearance. In multivariate analysis, female gender, a history of icteric hepatitis, concurrent HBV infection, and rs12979860 CC genotype remained independent variables associated with spontaneous HCV clearance. Spontaneous HCV clearance is more likely to occur in females, subjects with a history of icteric hepatitis, HBV coinfections, and those with the rs12979860 CC genotype.

Extreme heat is a significant public health concern in India; extreme heat hazards are projected to increase in frequency and severity with climate change. Few of the factors driving population heat vulnerability are documented, though poverty is a presumed risk factor. To facilitate public health preparedness, an assessment of factors affecting vulnerability among slum dwellers was conducted in summer 2011 in Ahmedabad, Gujarat, India. Indicators of heat exposure, susceptibility to heat illness, and adaptive capacity, all of which feed into heat vulnerability, was assessed through a cross-sectional household survey using randomized multistage cluster sampling. Associations between heat-related morbidity and vulnerability factors were identified using multivariate logistic regression with generalized estimating equations to account for clustering effects. Age, preexisting medical conditions, work location, and access to health information and resources were associated with self-reported heat illness. Several of these variables were unique to this study. As sociodemographics, occupational heat exposure, and access to resources were shown to increase vulnerability, future interventions (e.g., health education) might target specific populations among Ahmedabad urban slum dwellers to reduce vulnerability to extreme heat. Surveillance and evaluations of future interventions may also be worthwhile.

Using Terrestrial Laser Scanners to Calculate and Map Vertical Bridge Clearance

Science.gov (United States)

Zhang, C.; Arditi, D.; Chen, Z.

2013-08-01

The vertical clearance of a bridge over a highway is important in preventing oversized vehicles from hitting the bridge. The vertical clearance of a bridge is traditionally measured by using surveying equipment such as leveling rods and total stations. Typically, measurements are taken at multiple locations in order to determine the minimum vertical clearance under the bridge. This process is time and labor consuming. Also, these measurements may not be accurate because of the traffic, the uneven surface, and the reading error caused by the surveyor. Additionally, when one is faced with a multitude of reports especially in large projects with multiple ramps and bridges, it is not easy and it often takes a long time to find the bridge under study. This research provides a highly accurate measurement of the vertical bridge clearance by using terrestrial laser scanners. The clearance can be measured in the office by processing the collected point cloud data. The minimum vertical clearance is easily identified and the measurement is visualized and geo-referenced. An approach to reduce data noise caused by traffic is also introduced in this study. In addition, to help reduce the confusion of finding the bridge under study and to facilitate access to the clearance data, the clearance measurements are geo-referenced to an online mapping system. This system allows access to the final deliverable very easily through a single web portal. Finally, Illinois Department of Transportation's Circle Interchange is used to demonstrate this new method.

2008-01-01

Purpose: To study the epidemiology and clinical profile of victims of ocular trauma in an urban slum population. Materials and Methods: This cross-sectional study, conducted on 500 families each in three randomly selected urban slums in Delhi, collected demographic data for all members of these families, and clinical data for all those who suffered ocular trauma at any time, that required medical attention. Data was managed on SPSS 11.0. Results: Of 6704 participants interviewed, 163 episodes of ocular trauma were reported by 158 participants (prevalence = 2.4%, confidence interval = 2.0 to 2.7) Mean age at trauma was 24.2 years. The association between the age of participants and the history of ocular trauma was significant (P < 0.001), when adjusted for sex, education and occupation. Males were significantly more affected. Blunt trauma was the commonest mode of injury (41.7%). Blindness resulted in 11.4% of injured eyes ( P = 0.028). Of 6704 participants, 1567 (23.4%) were illiterate, and no association was seen between education status and trauma, when adjusted for sex and age at injury. A significant association was noted between ocular trauma and workplace (Chi-square = 43.80, P < 0.001), and between blindness and place (Chi-square = 9.98, P = 0.041) and source (Chi-square = 10.88, P = 0.028) of ocular trauma. No association was found between visual outcome and the time interval between trauma and first consultation (Chi-square = 0.50, P = 0.78), between receiving treatment and the best corrected visual acuity (Chi-square = 0.81, P = 0.81), and between the person consulted and blinding ocular trauma (Chi-square = 1.88, P = 0.170). Conclusion: A significant burden of ocular trauma in the community requires that its prevention and early management be a public health priority. PMID:18579991

The objective of the study was to assess the awareness and health-seeking practices related to cataract in urban slums of Delhi. This study design was a population-based cross-sectional study. Participants aged 18-60 years were recruited from randomly selected five slums of South Delhi. They were interviewed using a semi-structured interview schedule on awareness and eye health-seeking practices related to cataract. The practices were recorded if the respondents themselves or any other member of the family was diagnosed with cataract in previous 2 years. A total of 1552 respondents participated in the study, of which, 89.9% had heard of cataract but only (42%) were aware of any symptom of cataract. The common symptoms of cataract reported by the participants were white opacity in eyes (25.9%) and loss of vision (20.6%). Surgery as a treatment of cataract was known to only 559 (40.1%) participants. Awareness about surgery as treatment of cataract was significantly higher among people aged 45-60 years (adjusted odds ratio = 2.89, 95% confidence interval = 2.11-3.97) and in educated people (adjusted OR = 3.69 95% CI = 2.37-5.73). Out of 84 respondents who had been diagnosed with cataract, the health-seeking practices were observed by 70 (83.3%) participants. Among them, 51 (72.9%) had undergone surgery and another 19 (27.1%) had been advised to wait for surgery. Most of the operated patients 48 (94.1%) attended the postoperative follow-up. The study findings suggest the majority of participants have heard of cataract, but there is low awareness of its symptoms and treatment, and good eye health-seeking practices observed for cataract in urban slum population. Gaps in awareness observed can be filled up by implementing proper eye health education programs.

2017-10-01

Full Text Available Introduction: India has the highest prevalence of low birth weight babies. Geographical variation and level of physical activity can influence diet diversity and maternal nutritional status which in turn influences the birth weight of the neonate. Mumbai is a large city comprising of slums in suburbs depicting diet diversity amongst populations. Aim: To study the maternal diet diversity, physical activity and its effect on birth weight of the neonates in urban slums of Mumbai. Materials and Methods: A six month follow-up study was carried out in three maternity homes representing different geographical areas of Western, Central and Southern Mumbai. A total number of 131 pregnant women were selected using simple random sampling. Final sample size was n=121 after follow-up loss of 9 and 1 miscarriage. Maternal anthropometric, socio-demographic, physical activity and diet diversity data was collected using structured questionnaires through personal interview after taking written informed consent. Birth weight of the neonate was recorded. Chi-Square, Correlation, ANOVA was used to test the significance. A p-value of <0.05 was considered to be significant. Results: Nineteen (15.7% were low birth weight (LBW infants, 102 (84.3% had normal weight. There was a significant association between place of Antenatal Clinic (ANC visit and diet diversity score and its subsequent effect on birth weight (p<0.05. Geographic variation had an impact on diet diversity scores which in turn affected the birth weight of neonates. Women who delivered low birth weight babies were more involved in household domestic activities (p<0.05 compared to those women who delivered normal weight babies. Conclusion: Diet diversity and physical activity influence the birth weight of neonates across different geographic locations. Despite of ample interventions available to prevent maternal malnutrition, the incidence of LBW was not decreased. Thus, this issue needs to be addressed at

Predictors of incompletion of immunization among children residing in the slums of Kathmandu valley, Nepal: a case-control study

Full Text Available Abstract Background Immunization is one of the most effective health interventions averting an estimated 2–3 million deaths every year. In Nepal, as in most low-income countries, infants are immunized with standard WHO recommended vaccines. However, 16.4 % of children did not receive complete immunization by 12 months of age in Nepal in 2011. Studies from different parts of the world showed that incomplete immunization is even higher in slums. The objective of this study was to identify the predictors of incompletion of immunization among children aged 12–23 months living in the slums of Kathmandu Valley, Nepal. Methods The unmatched case-control study was conducted in 22 randomly selected slums of Kathmandu Valley. The sampling frame was first identified by complete enumeration of entire households of the study area from which 59 incompletely immunized children as cases and 177 completely immunized children as controls were chosen randomly in 1:3 ratio. Data were collected from the primary caretakers of the children. Backward logistic regression with 95 % confidence interval and adjusted odds ratio (AOR were applied to assess the factors independently associated with incomplete immunization. Result Twenty-six percent of the children were incompletely vaccinated. The coverage of BCG vaccine was 95.0 % while it was 80.5 % for measles vaccine. The significant predictors of incomplete immunization were the home delivery of a child, the family residing on rent, a primary caretaker with poor knowledge about the schedule of vaccination and negative perception towards vaccinating a sick child, conflicting priorities, and development of abscess following immunization. Conclusion Reduction of abscess formation rate can be a potential way to improve immunization rates. Community health volunteers should increase their follow-up on children born at home and those living in rent. Health institutions and volunteers should be influential in creating

To determine the influence of varying molecular weight (mol wt) on respiratory clearance of aerosolized solutes, we studied eight radiopharmaceuticals, each administered to four dogs: sodium /sup 99m/Tc pertechnetate (TcO4), /sup 99m/Tc glucoheptonate ([/sup 99m/Tc]GH), 51Cr-ethylenedinitrotetraacetate ([51Cr]EDTA), /sup 99m/Tc diethylenetriaminepentaacetate ([99mTc] DTPA), 111 In diethylenetriaminepentaacetate ([ 111 In]DTPA), 67 Ga desferoxaminemesylate ([ 67 Ga]DFOM), /sup 99m/Tc dextran ([/sup 99m/Tc]DX) and 111 In transferrin ([ 111 In]TF). After aerosolization (0.8 m MMD, 2.4 GSD), clearance was determined for 30 min and then corrected by intravenous injection for nonairspace radioactivity. In-TF clearance (0.11 +/- 0.10%/min) was lower than TcO4 (6.32 +/- 0.62%/min), [/sup 99m/Tc]GH (1.50 +/- 0.37%/min), [ 51 Cr]EDTA (2.38 +/- 1.02%/min), [/sup 99m/Tc]DTPA (3.51 +/- 0.40%/min), [ 111 In]DTPA (2.35 +/- 0.42%/min), [ 67 Ga] DFOM (1.99 +/- 0.49%/min) and [/sup 99m/Tc]DX (1.81 +/- 0.75%/min) clearances (p less than 0.001). TcO4 clearance was higher than others (p less than 0.001). Technetium binding to DX was unsatisfactory; aerosolization caused unbinding from DTPA. We conclude that respiratory clearance of large mol wt solutes within 30 min is negligible and, that clearance of molecules between 347-5099 daltons differs greatly, suggesting that binding and/or intrapulmonary retention affect transfer

Comparison of German and international clearance regulations - chances and limits for harmonization

International Nuclear Information System (INIS)

Thierfeldt, S.; Schartmann, F.

2005-01-01

The regulations on clearance in the German nuclear regulatory framework (especially sect. 29 and Annexes III and IV of the Radiation Protection Ordinance) are comprehensive and well founded. Germany has developed some of its clearance levels in advance of recommendations issued by the EC. Therefore, there are differences between the German and international clearance regulations. That has been investigated by a working group on clearance of the German Commission on Radiological Protection (SSK) which has performed an analysis of differences and their reasons for clearance levels in Germany and other countries (UK, The Netherlands, Sweden, USA and others). Differences can mainly be explained by country specific approaches in scenarios. Differences especially for the most relevant nuclides are not significant from a radiological point of view. The level of radiological protection (trivial dose range, a few 10 μSv/a) is guaranteed in all countries. The international discussion on the international harmonisation of clearance levels (mainly within the scope of the OECD/NEA and IAEA) can be enlightened on the basis of these results. This discussion concentrates on the question how far a harmonisation of clearance level values is actually necessary and possible. The IAEA Safety Guide RS-G-1.7 'Application of the concepts of exclusion, exemption and clearance' is of particular importance, because it proposes a set of values which might in the long-term take the role of international unconditional clearance levels. International harmonisation is only relevant for unconditional clearance of those materials, which are traded in large quantities among countries, in particular metal scrap. Harmonisation of the values to the same order of magnitude is sufficient. (orig.)

The early demonstration of lung involvement in systemic lupus erythematosus (SLE) patients is a difficult but important task. In the present study we attempted to identify abnormalities in pulmonary clearance of 99 mTc-DTPA in SLE, correlating their clearance data with clinical findings and disease activity. Forty-six consecutive SLE patients with and without active disease (LACC score) and 30 normal volunteers were studied. All subjects were submitted to pulmonary scintigraphy with 99 mTc-DTPA to evaluate the pulmonary clearance, and to a chest X-ray, and SLE patients were submitted to tests of disease activity, spirometry, arterial blood gases and tests to assess acute-phase proteins. Pulmonary clearance was faster in SLE patients with active disease when compared to normal controls [half-life of 67.04 min (51.52-82.55 min) in active SLE versus 85.87 min (78.85-92.87 min) in controls, P<0.05] and there was a higher frequency of abnormal clearance rates in patients with active disease (11 of 26 patients, 42.3%) when compared with SLE patients without disease activity (2 of 20 patients, 10%) (P = 0.04). A significant correlation was observed between the clearance rates and cough (P<0.05), but not between the clearance rates and dyspnoea symptoms or radiological findings, duration of SLE disease, antinuclear antibody titers and patterns, C-reactive protein or anti-double stranded DNA antibodies. We conclude that the pulmonary clearance of 99 m Tc-DTPA is increased in SLE patients with active disease. (author)

ENZYME-LINKED IMMUNOSORBENT ASSAY FOR SCREENING DIOXIN SOIL CONTAMINATION BY UNCONTROLLED COMBUSTION DURING INFORMAL RECYCLING IN SLUMS

Uncontrolled combustion due to garbage recycling is a widespread activity among slum dwellers in distressed economy countries and has been indicated as a major source of dioxin contamination. However, because of the high cost and complexity of gas chromatography/high-resolution mass spectrometry (GC-HRMS) analysis, the magnitude of the problem remains largely unknown. The present study describes a first approach toward the use of a dioxin antibody-based enzyme-linked immunosorbent assay (ELISA) as the basis for a sustainable, simple, and low-cost monitoring program to assess the toxicological impact of uncontrolled combustion in slums. A panel of 16 samples was analyzed by GC-HRMS and ELISA on split extracts. Close to 20% of the analyzed samples showed dioxin concentrations up to almost twice the guidance level for residential soil in several countries, pointing out the need for performing a large-scale monitoring program. Despite the potential for variations in dioxin congener distribution due to the mixed nature of the incinerated material, there was a good correlation between the toxic equivalents as determined by GC-HRMS and ELISA. Furthermore, an interlaboratory ELISA validation showed that the capacity to perform the dioxin ELISA was successfully transferred between laboratories. It was concluded that the ELISA method performed very well as a screening tool to prioritize samples for instrumental analysis, which allows cutting down costs significantly. PMID:18522475

Soil-transmitted helminths (STHs) are controlled by regular mass drug administration. Current practice targets school-age children (SAC) preferentially over pre-school age children (PSAC) and treats large areas as having uniform prevalence. We assessed infection prevalence in SAC and PSAC and spatial infection heterogeneity, using a cross-sectional study in two slum villages in Kibera, Nairobi. Nairobi has low reported STH prevalence. The SAC and PSAC were randomly selected from the International Emerging Infections Program's surveillance platform. Data included residence location and three stools tested by Kato-Katz for STHs. Prevalences among 692 analyzable children were any STH: PSAC 40.5%, SAC 40.7%; Ascaris: PSAC 24.1%, SAC 22.7%; Trichuris: PSAC 24.0%, SAC 28.8%; hookworm slums should be assessed separately in STH mapping. © The American Society of Tropical Medicine and Hygiene.

This paper describes associations among delivery-location, training of birth attendants, birthing practices, and early postpartum morbidity in women in slum areas of Dhaka, Bangladesh. During November 1993-May 1995, data on delivery-location, training of birth attendants, birthing practices, delivery-related complications, and postpartum morbidity were collected through interviews with 1,506 women, 489 home-based birth attendants, and audits in 20 facilities where the women from this study gave birth. Associations among maternal characteristics, birth practices, delivery-location, and early postpartum morbidity were specifically explored. Self-reported postpartum morbidity was associated with maternal characteristics, delivery-related complications, and some birthing practices. Dais with more experience were more likely to use potentially-harmful birthing practices which increased the risk of postpartum morbidity among women with births at home. Postpartum morbidity did not differ by birth-location. Safe motherhood programmes must develop effective strategies to discourage potentially-harmful home-based delivery practices demonstrated to contribute to morbidity.

Full Text Available This paper examines problem drinking, alcohol-related violence, and homelessness among youth living in the slums of Kampala—an understudied population at high-risk for both alcohol use and violence. This study is based on a cross-sectional survey conducted in 2014 with youth living in the slums and streets of Kampala, Uganda (n = 1134, who were attending Uganda Youth Development Link drop-in centers. The analyses for this paper were restricted to youth who reported current alcohol consumption (n = 346. Problem drinking patterns were assessed among youth involved in alcohol-related violence. Mediation analyses were conducted to examine the impact of homelessness on alcohol-related violence through different measures of problem drinking. Nearly 46% of youth who consumed alcohol were involved in alcohol-related violence. Problem drinkers were more likely to report getting in an accident (χ2 = 6.8, df = 1, p = 0.009, having serious problems with parents (χ2 = 21.1, df = 1, p < 0.0001 and friends (χ2 = 18.2, df = 1, p < 0.0001, being a victim of robbery (χ2 = 8.8, df = 1, p = 0.003, and going to a hospital (χ2 = 15.6, df = 1, p < 0.0001. For the mediation analyses, statistically significant models were observed for frequent drinking, heavy drinking, and drunkenness. Interventions should focus on delaying and reducing alcohol use in this high-risk population.

To describe the processes of care for secretion clearance in adult, intubated and mechanically ventilated patients in Australian and New Zealand Intensive Care Units (ICUs). A prospective, cross-sectional study was conducted through the Australian and New Zealand Intensive Care Society Clinical Trials Group (ANZICS CTG) Point Prevalence Program. Forty-seven ICUs collected data from 230 patients intubated and ventilated on the study day. Secretion clearance techniques beyond standard suctioning were used in 84/230 (37%) of patients during the study period. Chest wall vibration 34/84 (40%), manual lung hyperinflation 24/84 (29%), chest wall percussion 20/84 (24%), postural drainage/patient positioning 17/84 (20%) and other techniques including mobilisation 15/84 (18%), were the most common secretion clearance techniques employed. On average (SD), patients received airway suctioning 8.8 (5.0) times during the 24-h study period. Mucus plugging events were infrequent (2.7%). The additional secretion clearance techniques were provided by physiotherapy staff in 24/47 (51%) ICUs and by both nursing and physiotherapy staff in the remaining 23/47 (49%) ICUs. One-third of intubated and ventilated patients received additional secretion clearance techniques. Mucus plugging events were infrequent with these additional secretion clearance approaches. Prospective studies must examine additional secretion clearance practices, prevalence of mucus plugging episodes and impact on patient outcomes. Crown Copyright © 2017. Published by Elsevier Ltd.

Measurement of myocardial clearance rates between initial and delayed images is a major justification for adding computer quantification to the interpretation of exercise 201 TI images. To clarify the range of normal thallium clearance and its relationship to the level of exercise achieved, exercise thallium images in 89 normal subjects were analyzed: 45 asymptomatic subjects with less than 1% probability of coronary artery disease (CAD) (Group I), and 44 patients with chest pain found to have no significant CAD on angiography (Group II). Mean initial regional thallium uptake was similar in the two groups, but myocardial thallium clearance (mean +/- 1 s.d.) was slower in Group II, expressed as a longer half-life in the myocardium (8.2 +/- 7.6 hr compared with 3.4 +/- 0.7 hr p less than 0.001). Analysis of variance using ten clinical and exercise variables as covariates showed that the slower clearance in Group II was related to a lower peak exercise heart rate (HR) (154 +/- 27 compared with 183 +/- 11, respectively, p less than 0.001). By linear regression analysis, a decrease in peak HR of 1 beat/min was associated with a slower thallium clearance (longer half-life) of 0.05 hr. Using this formula, the clearance value in each patient was then corrected for peak exercise heart rate by decreasing measured clearance by 0.05 hr multiplied by the amount peak exercise heart rate which was below 183 (the mean value in Group I). There were no differences in the corrected clearance between the two groups. We conclude that thallium myocardial clearance after exercise is related in part to factors other than the presence of CAD, being slower when peak exercise HR is lower. Therefore, thallium clearance rates alone uncorrected for peak exercise heart rate should be used with caution when diagnosing CAD

A Study to Determine Clearance Levels of Radioactive Wastes in Kenya

Energy Technology Data Exchange (ETDEWEB)

Due to lack of a radioactive waste disposal facility in Kenya, radioactive wastes are stored in a bonded warehouse until such a time when their activity is low and they meet the criterion for clearance. The International Atomic Energy Agency (IAEA) has established activity concentrations of radionuclides to act as a universal guideline or standard for clearance in member countries. Radioactive wastes whose activity would yield a trivial risk to the people and environment, i.e. with an annual dose below 10 µSv are usually cleared from regulatory control with no further regulatory control mechanisms being taken. The Radiation Protection Board currently depends on the IAEA's generic clearance level activity concentrations for purposes of clearing the radiation wastes within its inventory. This study aims to determine activity concentrations of radionuclides in the Kenyan inventory that correspond to the clearance level dose of 10 µSv/a as set by the IAEA. The RESidual RADioactivity (RESRAD) computer code, an important tool developed in 1989 to aid in evaluation of sites with radioactive contamination, will aid in modeling these clearance level values using a pathways analysis method and available site-specific data from Kenya. Afterwards, the obtained clearance level values will be compared with the IAEA's generic clearance level values of the corresponding radionuclides. The results modeled using the RESRAD code are conservative. For most of the radionuclides in the Kenyan inventory, the values do correspond with the IAEA standard generic clearance level values, albeit with minor differences. For most of the radionuclides, the difference is within the acceptable uncertainty limit. For these low probability events the effective dose resulting from them should not exceed 1 mSv per year. Thus, consideration was given to doses to the skin and an equivalent dose to the skin of 50 mSv per year was duly used in estimating the clearance level activities. The

This study aims to determine the prevalence of primary headache disorders using the second edition of international classification of headache disorders among urban slum dwellers. Headache is a common neurological disorder and one of the most common reasons for visiting the neurology clinics in Nigeria. Low socioeconomic status has been linked with primary headaches. Factors that may precipitate and sustain headaches are common in Africa especially in urban slums. There are limited population based data on the prevalence of headache from Nigeria and other African countries. A 3 phase cross-sectional descriptive study was done to survey at least 40% of the adult population (Igbos) living in an urban slum using the International Classification of Headache Disorders 2nd Edition (ICHD-I) criteria using a validated Igbo language adaptation (translation and back-translation into Igbo language) of a World Health Organization protocol for screening neurological disorders in the community. The lifetime prevalence of headache of any type was 66.7% (95% confidence interval [CI] 64.2-69.2), significantly higher in females (70.2% [95% CI 67.0-73.4]) than in males (62.3% [95% CI 58.5-66.1]; P = .0.002). The prevalence of primary headaches was also significantly lower in males than in females (44.9% [95% CI 45.5-53.3] vs 53.2% (95% CI 49.3-57.1), P = .002). Female (52.1%) drinkers had a statistically higher prevalence of primary headaches than male drinkers (43.6%; P = .004). The prevalence of migraine was 6.4% (95% CI 5.1-7.7); 7.5% (95% CI 5.6-9.4) in females and 5% (95% CI 3.3-6.7) in males (P = .058). Migraine with aura was similar in both males and females. Migraine without aura was significantly higher in females (5.7%) than males (3.1%) (P = .022). Tension-type headache (TTH) had an overall prevalence of 13.8% (95% CI 11.3-16.3), males 12.2% (95% CI 9.7-14.7), and females 15.1% (95% CI 12.6-17.6; P = .118.)

Full Text Available Abstract Background Drug resistance in Plasmodium falciparum is common in many endemic and other settings but there is no clear recommendation on when to change therapy when there is delay in parasite clearance after initiation of therapy in African children. Methods The factors contributing to delay in parasite clearance, defined as a clearance time > 2 d, in falciparum malaria were characterized in 2,752 prospectively studied children treated with anti-malarial drugs between 1996 and 2008. Results 1,237 of 2,752 children (45% had delay in parasite clearance. Overall 211 children (17% with delay in clearance subsequently failed therapy and they constituted 72% of those who had drug failure, i.e., 211 of 291 children. The following were independent risk factors for delay in parasite clearance at enrolment: age less than or equal to 2 years (Adjusted odds ratio [AOR] = 2.13, 95% confidence interval [CI]1.44-3.15, P 50,000/ul (AOR = 2.21, 95% CI = 1.77-2.75, P 20000/μl a day after treatment began, were independent risk factors for delay in clearance. Non-artemisinin monotherapies were associated with delay in clearance and treatment failures, and in those treated with chloroquine or amodiaquine, with pfmdr 1/pfcrt mutants. Delay in clearance significantly increased gametocyte carriage (P Conclusion Delay in parasite clearance is multifactorial, is related to drug resistance and treatment failure in uncomplicated malaria and has implications for malaria control efforts in sub-Saharan Africa.

Around 86% of births in Mumbai, India, occur in healthcare institutions, but this aggregate figure hides substantial variation and little is known about urban home births. We aimed to explore factors influencing the choice of home delivery, care practices and costs, and to identify characteristics of women, households and the environment which might increase the likelihood of home birth. As part of the City Initiative for Newborn Health, we used a key informant surveillance system to identify births prospectively in 48 slum communities in six wards of Mumbai, covering a population of 280,000. Births and outcomes were documented prospectively by local women and mothers were interviewed in detail at six weeks after delivery. We examined the prevalence of home births and their associations with potential determinants using regression models. We described 1708 (16%) home deliveries among 10,754 births over two years, 2005-2007. The proportion varied from 6% to 24%, depending on area. The most commonly cited reasons for home birth were custom and lack of time to reach a healthcare facility during labour. Seventy percent of home deliveries were assisted by a traditional birth attendant (dai), and 6% by skilled health personnel. The median cost of a home delivery was US$ 21, of institutional delivery in the public sector US$ 32, and in the private sector US$ 118. In an adjusted multivariable regression model, the odds of home delivery increased with illiteracy, parity, socioeconomic poverty, poorer housing, lack of water supply, population transience, and hazardous location. We estimate 32,000 annual home births to residents of Mumbai's slums. These are unevenly distributed and cluster with other markers of vulnerability. Since cost does not appear to be a dominant disincentive to institutional delivery, efforts are needed to improve the client experience at public sector institutions. It might also be productive to concentrate on intensive outreach in vulnerable areas by

Effect of glucose-insulin-potassium infusion on thallium myocardial clearance

1983-01-01

Factors influencing the rate of 201 Tl clearance from the myocardium have not been clearly defined. This study determined the effect of an intravenous infusion of glucose-insulin-potassium (GIK) on the net 201 Tl clearance rates from myocardium with and without initial 201 Tl loading. Anesthetized open-chest dogs underwent 5 min of left anterior descending coronary artery occlusion and intravenous 201 Tl was injected and the occlusion released 5 min later. Thirty minutes after 201 Tl injection, 30 ml of either GIK (nine dogs) or saline (five dogs) was infused intravenously. The clearance rates of 201 Tl from the anterior wall (without initial 201 Tl loading) and from the posterior wall (with initial 201 Tl loading) were monitored with miniaturized cadmium telluride detectors placed on the myocardium. Calculation of net myocardial clearance rates was performed by linear regression analysis from serial 1 min counts. Compared with saline infusion, GIK increased the net clearance of 201 Tl from both myocardial regions with and without initial loading. The most marked change induced by GIK infusion was in the myocardial region without initial 201 Tl loading; a net increase in 201 Tl activity (72 +/- 42 cpm/30 min) was converted into a net loss (-594 +/- 228 cpm/30 min). There was no significant change in 201 Tl clearance after the saline infusion. Heart rate, aortic and left atrial pressure, sonomicrometer-measured transmural myocardial wall thickness, microsphere-determined myocardial blood flow, and blood glucose and potassium concentrations did not change significantly during GIK or saline infusions. Thus, GIK infusion appears to increase net 201 Tl clearance from myocardial zones with and without initial 201 Tl loading

The importance of clearance measurements in evaluating renal or hepatic function needs not further demonstration. The isotopic methods were proved in renal exploration but their utilization in exploration of hepato-biliary function needs to be evaluated. In this work we have compared the measurement of plasma clearance by Mebrofenine, a radiopharmaceutical of specifically hepatic elimination, with the reference method, the clearance of indocyanine green. On the basis of scintigraphic data from 23 patients who benefited by a hepato-biliary exploration by Mebrofenine- 99m Tc for pre-surgery account and surveillance, we have determined the plasma clearance of this radiopharmaceutical. The method makes use of the curve of normalized cardiac activity by a blood sampling, taken 60 minutes after injection. The measurement of the clearance of indocyanine green was effected within a delay inferior to 1 month from the moment of biliary scintigraphy. The average clearance of Mebrofenine- 99m Tc is of 553 ml/min for 1.73 m 2 of corporal surface (typical interval is 374 ml/min), the value of indocyanine green is of 450 ml/min (typical interval is 229 ml/min). The two measurements of clearance are correlated (p = 0.05). In conclusion, the measurement of clearance by Mebrofenine- 99m appears to be adapted to the evaluation of hepato-biliary function

Leong, Julie V B; Boro, Maureen S; Winter, Michaele

2011-04-01

Two methods of calculating vancomycin clearance were compared to determine the best body weight measure to use when dosing vancomycin for overweight and obese patients. Hospitalized veterans weighing more than 120% of their ideal body weight (IBW) with serum vancomycin concentrations (SVCs) drawn between January 1, 2003, and June 30, 2005, were eligible for study inclusion. Exclusion criteria included weight of more than 300% the IBW, unstable renal function, dialysis, uncertain vancomycin dosing or sampling times, and distribution-phase sampling. Data from January 1 through December 31, 2003 (phase 1) determined the best-fit weight for vancomycin clearance for the Leonard and Boro method. The bias and precision of the modified Leonard and Boro method using the best-fit weight for vancomycin clearance were then compared with those of the Rushing and Ambrose method for predicting SVCs from January 1, 2004, through June 30, 2005 (phase 2). Forty-eight patients were included in phase 1, with 67 SVCs for analysis. During phase 1, adjusted body weight (ABW), using the Leonard and Boro method, was superior in predicting vancomycin clearance and the resultant SVCs. A total of 96 patients were included in phase 2 of the study, with 160 SVCs for analysis. The modified Leonard and Boro method was significantly more precise than the Rushing and Ambrose method in predicting vancomycin clearance. Use of ABW proved to be superior compared with total body weight when estimating vancomycin clearance in overweight and obese patients. While there was no difference in bias between methods, the modified Leonard and Boro method was significantly more precise than the Rushing and Ambrose method in predicting SVCs when dosing vancomycin for obese patients.

Tip clearance effect on through-flow and performance of a centrifugal compressor

Eum, Hark Jin; Kang, Young Seok; Kang, Shin Hyoung

2004-01-01

Numerical simulations have been performed to investigate tip clearance effect on through-flow and performance of a centrifugal compressor which has the same configuration of impeller with six different tip clearances. Secondary flow and loss distribution have been surveyed to understand the flow mechanism due to the tip clearance. Tip leakage flow strongly interacts with mainstream flow and considerably changes the secondary flow and the loss distribution inside the impeller passage. A method has been described to quantitatively estimate the tip clearance effect on the performance drop and the efficiency drop. The tip clearance has caused specific work reduction and additional entropy generation. The former, which is called inviscid loss, is independent of any internal loss and the latter, which is called viscous loss, is dependent on every loss in the flow passage. Two components equally affected the performance drop as the tip clearances were small, while the efficiency drop was influenced by the viscous component alone. The additional entropy generation was modeled with all the kinetic energy of the tip leakage flow. Therefore, the present paper can provide how to quantitatively estimate the tip clearance effect on the performance and efficiency

Tear clearance implications for ocular surface health.

2004-03-01

Tear clearance/turnover provides a global assessment of the function of the lacrimal functional unit and of tear exchange on the ocular surface. It is an indirect measure of dry eye induced inflammation on the ocular surface. It shows better correlation with the severity of ocular irritation symptoms and corneal epithelial disease in dry eye than the Schirmer 1 test. Delayed tear clearance may prove to be the best measure for identifying patients with tear film disorders who may respond to anti-inflammatory therapy.

Clearance of Tc-99m DTPA in hemodialysis and peritoneal dialysis: concise communication

International Nuclear Information System (INIS)

Wainer, E.; Boner, G.; Lubin, E.; Rosenfeld, J.B.

1981-01-01

The clearance of Tc-99m DTPA was studied in 14 patients undergoing hemodialysis (HD) or peritoneal dialysis (PD). Mean Tc-99m DTPA clearance during HD was 37.8% +/- 10.1 of creatinine clearance. Mean Tc-99m DTPA clearance in PD was 65.1% +/- 10.3 of creatinine clearance. Tc-99m DTPA, with a larger molecular weight than that of creatinine, is cleared relatively better during PD than during HD. Thus Tc-99m DTPA may be used in the assessment of the effectiveness of different dialytic treatments for substances of similar molecular weight. In addition, our study shows that clearance of DTPA both in HD and PD is sufficiently high to allow the removal of this chelating agent in patients with renal failure

Access to and utilisation of quality healthcare promotes positive child health outcomes. However, to be optimally utilised, the healthcare system needs to be responsive to the expectations of the population it serves. Health systems in many sub-Saharan African countries, including Malawi, have historically focused on promoting access to health services by the rural poor. However, in the context of increasing urbanisation and consequent proliferation of urban slums, promoting health of children under five years of age in these settings is a public health imperative. We conducted a discrete choice experiment to determine the relative importance of health facility factors in seeking healthcare for childhood illnesses in urban slums of Malawi. Caregivers of children under five years of age were presented with choice cards that depicted two hypothetical health facilities using six health facility attributes: availability of medicines and supplies, thoroughness of physical examination of the child, attitude of health workers, cost, distance, and waiting time. Caregivers were asked to indicate the health facility they would prefer to use. A mixed logit model was used to estimate the relative importance of and willingness to pay (WTP) for health facility attributes. Attributes with greatest influence on choice were: availability of medicines and supplies (β = 0.842, ppay 1.8 and 2.4 times more for medicine availability over thorough examination and positive attitude of health workers respectively. Therefore, strengthening health service delivery system through investment in sustained availability of essential medicines and supplies, sufficient and competent health workforce with positive attitude and clinical discipline to undertake thorough examination, and reductions in waiting times have the potential to improve child healthcare utilization in the urban slums.

Effect of isolated hepatic ischemia on organic anion clearance and oxidative metabolism.

1992-04-01

Hepatic failure is frequently seen following severe hemorrhagic shock, sepsis, and trauma. Clearance of various drugs has been used to evaluate hepatocellular dysfunction, including indocyanine green (ICG), an organic anionic dye that is transported similarly to bilirubin, and antipyrine (AP), a marker of oxidative phosphorylation. Previous investigators have noted a decrease in ICG excretion following systemic hemorrhage. The effect of isolated hepatic ischemia on the clearances of ICG and AP was studied in 16 pigs after 90 minutes of vascular occlusion to the liver. Antipyrine clearance decreased almost 50% from baseline values at 24 and 72 hours after the ischemia procedure, indicating a significant depression in the cytochrome P-450 system. On the other hand, ICG clearance did not change significantly. In conclusion, ICG clearance is not depressed after isolated hepatic ischemia in pigs. Changes in organic anion clearance after systemic hemorrhage may be because of release of toxic products from ischemic peripheral tissue.

Clearance of 99mTc-DTPA and experimentally increased alveolar surfactant content

1992-01-01

The authors measured clearance of 99m Tc-labeled diethylenetriamine pentaacetic acid ( 99m Tc-DTPA) in rabbits with experimentally increased alveolar surfactant content. In one group of animals, surfactant production was increased by treatment with ambroxol, and another group of animals was treated with tracheal instillation of natural surfactant. A group of untreated control animals and animals treated with instillation of saline were also studied. Clearance was measured during standard conditions of mechanical ventilation and during ventilation with large tidal volumes. In ambroxol- and surfactant-treated groups, clearance rate was reduced compared with untreated control animals. In contrast, clearance rate increased after saline instillation. The differences were observed at both modes of ventilation. The findings indicate that the pulmonary surfactant system is a rate-limiting factor for the clearance of 99m Tc-DTPA and that the volume dependence of clearance is not explained by stretching of the alveolar wall only. 28 refs., 2 figs., 1 tab

Inequalities in maternity care and newborn outcomes: one-year surveillance of births in vulnerable slum communities in Mumbai

Full Text Available Abstract Background Aggregate urban health statistics mask inequalities. We described maternity care in vulnerable slum communities in Mumbai, and examined differences in care and outcomes between more and less deprived groups. Methods We collected information through a birth surveillance system covering a population of over 280 000 in 48 vulnerable slum localities. Resident women identified births in their own localities and mothers and families were interviewed at 6 weeks after delivery. We analysed data on 5687 births over one year to September 2006. Socioeconomic status was classified using quartiles of standardized asset scores. Results Women in higher socioeconomic quartile groups were less likely to have married and conceived in their teens (Odds ratio 0.74, 95% confidence interval 0.69–0.79, and 0.82, 0.78–0.87, respectively. There was a socioeconomic gradient away from public sector maternity care with increasing socioeconomic status (0.75, 0.70–0.79 for antenatal care and 0.66, 0.61–0.71 for institutional delivery. Women in the least poor group were five times less likely to deliver at home (0.17, 0.10–0.27 as women in the poorest group and about four times less likely to deliver in the public sector (0.27, 0.21–0.35. Rising socioeconomic status was associated with a lower prevalence of low birth weight (0.91, 0.85–0.97. Stillbirth rates did not vary, but neonatal mortality rates fell non-significantly as socioeconomic status increased (0.88, 0.71–1.08. Conclusion Analyses of this type have usually been applied across the population spectrum from richest to poorest, and we were struck by the regularly stepped picture of inequalities within the urban poor, a group that might inadvertently be considered relatively homogeneous. The poorest slum residents are more dependent upon public sector health care, but the regular progression towards the private sector raises questions about its quality and regulation. It also

Sexually transmitted infections (STIs) still stand as one of the commonest health problems affecting women of reproductive age. The knowledge and practices of STIs, among susceptible populations such as women of reproductive age, living in slums like Katanga in Kampala Uganda need to be established. This was a cross-sectional study with 339 participants in Katanga slum. Data was collected using an interviewer administered questionnaire, entered and analysed using SPSS version 17.0. Data was summarized using frequencies for categorical data and medians for continuous data. Majority of the participants (71.9%) were ≥25years with a mean age of 28.0(SD ±7.0) years. The commonest symptoms known to the participants were genital itching (60%) and genital rash (14.5%). Most mentioned multiple partners (63.7%) and unprotected sex (50.7%) as predisposing factors to STIs. Knowledge on methods of prevention was high (92.3%) however, 18.8% were found positive for STIs using the syndromic approach and 82% mentioned having suffered from STIs in the past 6 months more than once. Most participants did not know about the systemic effects of STIs to their health and didnot follow the appropriate behavior patterns despite being knowledgeable about the various methods of prevention of STIs.

Inspired air humidification has been reported to show some benefit in bronchiectatic patients. We have investigated the possibility that one effect might be to enhance mucociliary clearance. Such enhancement might, if it occurs, help to lessen the risks of recurrent infective episodes. Using a radioaerosol technique, we measured lung mucociliary clearance before and after 7 days of domiciliary humidification. Patients inhaled high flow saturated air at 37 degrees C via a patient-operated humidification nasal inhalation system for 3 h per day. We assessed tracheobronchial mucociliary clearance from the retention of (99m)Tc-labelled polystyrene tracer particles monitored for 6 h, with a follow-up 24-h reading. Ten out of 14 initially recruited patients (age 37-75 years; seven females) completed the study (two withdrew after their initial screening and two prior to the initial clearance test). Seven patients studied were non-smokers; three were ex-smokers (1-9 pack-years). Initial tracer radioaerosol distribution was closely similar between pre- and post-treatment. Following humidification, lung mucociliary clearance significantly improved, the area under the tracheobronchial retention curve decreased from 319 +/- 50 to 271 +/- 46%h (p humidification treatment improved lung mucociliary clearance in our bronchiectatic patients. Given this finding plus increasing laboratory and clinical interest in humidification mechanisms and effects, we believe further clinical trials of humidification therapy are desirable, coupled with analysis of humidification effects on mucus properties and transport.

Impairment of nasal mucociliary clearance in woodworkers in the furniture industry. Measurements of mucociliary clearance from the anterior end of the middle turbinate were made using technetium-99m-labelled particles in nine woodworkers from the furniture industry and in 12 controls, none of whom had been occupationally exposed to wood dust. Clearance rates in the controls ranged from 1·9 to 18·5 mm min-1 with a mean of 6·8. These values are in good agreement with measurements reported elsewhere for normal subjects. Only one of the woodworkers had a clearance rate which fell within the normal range and he had been occupationally exposed for the shortest period (6 years). In four woodworkers clearance was very slow (furniture industry for more than 10 years. PMID:4821406

The renal clearance of 99m Tc-MDP was measured in 13 patients who had bone scans and compared with the renal clearance of 51 Cr-EDTA. No difference was found between the renal clearance of the two tracers, showing a close correlation (r = 0.98). These data suggest that the 99m Tc-MDP is excreted by the kidneys by glomerular filtration without tubular secretion. (orig.) [de

It has been suggested that blood flow have little effect on the lung clearance of Tc-99m DTPA which depends on the alveolar distension. However an increase of pulmonary blood flow, induces a recruitment of new vascular areas which can enhance this clearance. To assess this hypothesis the pulmonary apical and basal clearances of a sumicronic aerosol of Tc-99m DTPA were studied at rest and at exercise in seven non smoking volunteers in upright posture. As a matter of fact exercising upright is known to increase primarily the apical blood flow. After inhalation the subjects were seated on a bicycle their back against a gamma camera which was linked to a computer. The lung radioactivity was registered successively during a resting and an exercising period. At rest there was a gradient of clearance from the apex to the base of the lung, the apical clearance being significantly higher. At exercise (50 Watts, 60 c. min /sup -1/, 7 min.) this regional gradient was enhanced by a large and significant increase of the apical clearances (0.0340 min /sup -1/ +-0.0063 SD versus 0.00183 min /sup -1/ +- 0.074 SD at rest, n = 7, p < 0.01). By contrast the changes of the basal clearances were slight and unsignificant (0.0146 min /sup -1/ +- 0.0062 SD versus 0.0140 min /sup -1/ +- 0.0082 SD). Since exercise induces little distension of the apical alveoli but drastically enhances the apical blood flow, the observed increase of the apical lung clearance could be primarily attributed to the recruitment of new capillaries induced by exercise in the apices. This led to an increase of the surface area permeability product

To evaluate the relative partial pressure in oxygen (pO2) at the corneal surface under Boston XO2 scleral lenses (SL) fitted with targeted clearances of 200 and 400 μm (SL200 and SL400). During this prospective study, the right eyes of eight normal subjects were fitted with SL200 and SL400. Clearance, validated after 5 minutes of wear with an optical coherence tomograph, was used with lens thicknesses to calculate transmissibility and estimate pO2. Corneal pO2s were measured with an oxygen electrode after 5 minutes of (1) corneal exposure to calibrating gases with various pO2 or of (2) SL wear. Decays in pO2 were modeled to an exponential. Linear regression between exponent k of these decays and calibrating gas pO2s allowed for the calculation of corneal pO2 under SL. Differences between pO2s beneath SL200 and SL400 were tested with a mixed ANOVA. The estimated transmissibility based on thicknesses and clearances (239.7 ± 34.7; 434.5 ± 33.2 μm) predicted a corneal pO2 of 8.52 ± 0.51 and 6.37 ± 0.28% for SL200 and SL400. These values were close to measured pO2: 9.07 ± 0.86 and 6.19 ± 0.87% (mean ± SEM) (P time, an 18-mm scleral lens fitted with a 400-μm clearance reduces the oxygen tension available to the cornea by 30% compared to a similar lens fitted with a 200-μm clearance after 5 minutes of wear.

Submicrometric sulfuric acid (H2SO4) aerosol can affect mucociliary clearance without eliciting irritative symptoms or changes in pulmonary function. The effect of larger fog droplets containing H2SO4 on mucociliary clearance is unknown. We quantified mucociliary clearance from the trachea (n = 4) and small airways (n = 7) of young healthy male adults after an acute exposure to H2SO4 fog (MMAD = 10.3 microns; pH = 2.0; liquid water content = 481 +/- 65 mg/m3; osmolarity = 30 mOsm). Acid fog (AF) or saline fog (SF) (10.9 microns; 492 +/- 116 mg/m3; 30 mOsm) was administered for 40 min of unencumbered breathing (no mouth-piece) at rest and for 20 min of exercise sufficient to produce oronasal breathing. Fog exposures were followed by a methacholine (MCh) challenge (a measure of airway reactivity) or inhalation of technetium-99M radioaerosol (MMAD = 3.4 microns) on 2 study days each. Changes in symptoms and forced ventilatory function were also assessed. Clearance was quantified from computer-assisted analyses of gamma camera images of the lower respiratory tract in terms of %removal/min of the radiolabel from the trachea 25 min after inhalation and from the outer zone of the right lung after 1.9 to 3 h. Symptoms, forced ventilatory function, and MCh response were unaffected by either fog. Tracheal clearance was more rapid in four of four subjects after AF (0.83 +/- 1.58% removal/min) compared with that after SF (-0.54 +/- 0.85% removal/min). Outer zone clearance was more rapid in six of seven subjects after AF (0.22 +/- 0.15% removal/min) compared with that after SF (0.01 +/- 0.09% removal/min)

Dimerization of glycoprotein Ibα is not sufficient to induce platelet clearance.

ESSENTIALS: Many anti-glycoprotein (GP)Ibα antibodies induce platelet clearance in a dimer-dependent manner. Characterization of monoclonal antibodies that bind the mechanosensitive domain (MSD) of GPIbα. An anti-MSD antibody binds two copies of GPIbα in platelets but does not induce platelet clearance. The prevailing clustering model of GPIbα signaling is incorrect or needs revision. The mechanism of platelet clearance is not clear. Many antibodies binding the membrane-distal ligand-binding domain of glycoprotein (GP)Ibα induce rapid clearance of platelets and acute thrombocytopenia, which requires the bifurcated antibody structure. It was thought that binding of these antibodies induced lateral dimerization or clustering of GPIbα in the plasma membrane, which leads to downstream signaling and platelet clearance. However, many antibodies targeting GPIbβ and GPIX, which are associated with GPIbα in the GPIb-IX complex, do not induce platelet clearance, which is in contradiction to the clustering model. To test whether dimerization or clustering of GPIbα is sufficient to transmit the signal that leads to platelet clearance. We have recently raised several mAbs targeting the mechanosensitive domain (MSD) of GPIbα. Binding of these anti-MSD antibodies was characterized with biochemical methods. Their ability to stimulate platelets and induce platelet clearance in mice was assessed. Infusion of anti-MSD antibodies does not cause thrombocytopenia in mice. These antibodies show no detectable effects on platelet activation and aggregation in vitro. Further biochemical investigation showed that the anti-MSD antibody 3D1 binds two copies of GPIbα on the platelet surface. Therefore, lateral dimerization of GPIbα induced by antibody binding is not sufficient to initiate GPIb-IX signaling and induce platelet clearance. Our results suggest that a factor other than or in addition to clustering of GPIbα is required to induce platelet clearance. © 2015 International

Although mental health research in India has gained momentum in recent years and several epidemiological studies have begun to quantify psychiatric morbidities, there are few community-based epidemiological studies focusing specifically on prevalence and associated risk factors of emotional and behavioral disorders among children. A cross-sectional study was conducted in an urban slum of Karimnagar, Andhra Pradesh among 370 children selected by simple random sampling. Strength and difficulty questionnaire (SDQ) was used to estimate the prevalence of emotional and behavioral disorder. A semi-structured questionnaire was used to evaluate the social predictors of the condition, health-seeking behavior, and its impact on educational status of the children. Maternal depression was evaluated using patient health questionnaire (PHQ-9). Eighty-three (22.43%) children had an abnormal score on at least one domain of SDQ. Logistic regression analysis indicated that male gender (odds ration (OR) = 5.51), under-nutrition (OR = 2.74), low socioeconomic status (OR = 3.73), nuclear family (OR = 1.89), working status of the mother (OR = 2.71), younger age of the mother at the birth of the child (OR = 3.09), disciplinary method (OR = 2.31), financial problem at home (OR = 13.32), alcoholic father (OR = 11.65), conflicts in family (OR = 7.29), and depression among mother (OR = 3.95) were significant predictors. There was a significant impact on educational performance (p = 0.008) and parents had little awareness regarding the condition. The high frequency of emotional and behavioral problems, its impact on educational performance of the children, associated adverse social factors, poor knowledge, and treatment-seeking behavior of the parents in an urban slum warrants immediate attention. The interrelation of all these factors can be utilized to plan a continuum of comprehensive services that focus on prevention, early identification, and effective intervention strategies with

Full Text Available Background: India was the first country to launch National Family Planning Program in 1952. Even though various measures have been taken to encourage the usage of contraception but the achievement in this field was not to the extent expected due to various social and cultural factors. Objective: This study was planned to assess the prevalence and its determinants of unmet need for contraception among eligible couples in urban slums of Raipur city. Methodology: A cross sectional community based study was conducted using cluster sampling in urban slums of Raipur city from November 2011 to October 2012. During the study, 711 fecund married women, age group 15-49 years were included and predesigned and pretested proforma was used as a study tool. The obtained data were analyzed using appropriate statistical test. Results: Among all eligible married women 45 % were concentrated in the prime reproductive age 20-29 yrs. Majority of women were not educated. The total unmet need for family planning comes out to 32.9%. Age, Education, literacy, Occupation, Type of Family, No of living children, Birth Order , No of male child, No of female child , Husband literacy were the most significant predictor of unmet need. Conclusion: Percentage of unmet need is higher as compared to national data, so there is urgently need to ensure the same.
