    Phytoremediation is an effective, non-intrusive, inexpensive, aesthetically pleasing, socially accepted, promising phytotechnology for the remediation of polluted soils. The objective of any soil remediation process must be not only to remove the contaminant(s) from the soil but, most importantly, to restore the continued capacity of the soil to perform or function according to its potential (i.e., to recover soil health). Hence, indicators of soil health are needed to properly assess the efficiency of a phytoremediation process. Biological indicators of soil health, especially those related to the size, activity and diversity of the soil microbial communities, are becoming increasingly used, due to their sensitivity and capacity to provide information that integrates many environmental factors. In particular, microbial indicators of soil health are valid tools to evaluate the success of metal phytoremediation procedures such as phytoextraction and phytostabilization processes.

    The past decades have been a golden era during which great tasks were accomplished in the field of microbiology, including food microbiology. In the past, culture-dependent methods have been the primary choice to investigate bacterial diversity. However, using cultureindependent high-throughput sequencing of 16S rRNA genes has greatly facilitated studies exploring the microbial compositions and dynamics associated with health and diseases. These culture-independent DNA-based studies generate large-scale data sets that describe the microbial composition of a certain niche. Consequently, understanding microbial diversity becomes of greater importance when investigating the composition, function, and dynamics of the microbiota associated with health and diseases. Even though there is no general agreement on which diversity index is the best to use, diversity indices have been used to compare the diversity among samples and between treatments with controls. Tools such as the Shannon- Weaver index and Simpson index can be used to describe population diversity in samples. The purpose of this review is to explain the principles of diversity indices, such as Shannon- Weaver and Simpson, to aid general microbiologists in better understanding bacterial communities. In this review, important questions concerning microbial diversity are addressed. Information from this review should facilitate evidence-based strategies to explore microbial communities.

    eHealth indicators are needed to measure defined aspects of national eHealth implementations. However, until now, eHealth indicators are ambiguous or unclear. Therefore, an expert workshop "Towards an International Minimum Dataset for Monitoring National Health Information System Implementations......" was organized. The objective was to develop ideas for a minimum eHealth indicator set. The proposed ideas for indicators were classified based on EUnetHTA and De-Lone & McClean, and classification was compared with health IT evaluation criteria classification by Ammenwerth & Keizer. Analysis of the workshop...... results emphasized the need for a common methodological framework for defining and classifying eHealth indicators. It also showed the importance of setting the indicators into context. The results will benefit policy makers, developers and researchers in pursuit of provision and use of evidence...

    Full Text Available Worldwide coliform bacteria are used as indicators of fecal contamination and hence, the possible presence of disease causing organisms. Therefore, it is important to understand the potential and limitations of these indicator organisms before realistically implementing guidelines and regulations to safeguard our water resources and public health. This review addresses the limitations of current faecal indicator microorganisms and proposed significant alternative microbial indicators of water and wastewater quality. The relevant literature brings out four such significant microbial water pollution indicators and the study of these indicators will reveal the total spectrum of water borne pathogens. As E.coli and enterococci indicates the presence of bacterial pathogens, Coliphages indicate the presence of enteric viruses, and Clostridium perfringens, an obligate anaerobe, indicates presence of parasitic protozoan and enteric viruses. Therefore, monitoring a suite of indicator organisms in reclaimed effluent is more likely to be predictive of the presence of certain pathogens in order to protect public health, as no single indicator is most highly predictive of membership in the presence or absence category for pathogens.

    Traditional bacterial indicators used in public health to assess water quality and the Biolog® system were evaluated to compare their response to biological, chemical, and physical habitat indicators of stream condition both within the state of Oregon and among ecoregion aggregates (Coast Range, Willamette Valley, Cascades, and eastern Oregon). Forty-three randomly selected Oregon river sites were sampled during the summer in 1997 and 1998. The public health indicators included heterotrophic plate counts (HPC), total coliforms (TC), fecal coliforms (FC) and Escherichia coli (EC). Statewide, HPC correlated strongly with physical habitat (elevation, riparian complexity, % canopy presence, and indices of agriculture, pavement, road, pasture, and total disturbance) and chemistry (pH, dissolved O2, specific conductance, acid-neutralizing capacity, dissolved organic carbon, total N, total P, SiO2, and SO4). FC and EC were significantly correlated generally with the river chemistry indicators. TC bacteria significantly correlated with riparian complexity, road disturbance, dissolved O2, and SiO2 and FC. Analyzing the sites by ecoregion, eastern Oregon was characterized by high HPC, FC, EC, nutrient loads, and indices of human disturbance, whereas the Cascades ecoregion had correspondingly low counts of these indicators. The Coast Range and Willamette Valley presented inconsistent indicator patterns that are more difficult to characterize. Attempts to distinguish between ecoregions with the Biolog system were not successful, nor did a statistical pattern emerge between the first five principle components and the other environmental indicators. Our research suggests that some traditional public health microbial indicators may be useful in measuring the environmental condition of lotic systems.

    2016-12-01

    Land-use change from native forest to intensive agricultural systems can negatively impact numerous soil parameters. Understanding the effects of forest ecosystem transformations on markers of long-term soil health is particularly important in rapidly developing regions such as Nepal, where unprecedented levels of agriculturally-driven deforestation have occurred in recent decades. However, the effects of widespread land use changes on soil quality in this region have yet to be properly characterized. Microbial indicators (soil microbial biomass, metabolic quotient and enzymes activities) are particularly suited to assessing the consequences of such ecosystem disturbances, as microbial communities are especially sensitive to environmental change. Thus, the aim of this study was to assess the effect of land use system; i.e. forest, organic and conventional farming, on soil quality in Chitwan, Nepal using markers of microbial community size and activity. Total organic C and N contents were higher in organic farming compared with conventional farming and forest, suggesting higher nutrient retention and soil preservation with organic farming practices compared to conventional. These differences in soil composition were reflected in the health of the soil microbial communities: Organic farm soil exhibited higher microbial biomass C, elevated β-glucosidase and chitinase activities, and a lower metabolic quotient relative to other soils, indicating a larger, more active, and less stressed microbial community, respectively. These results collectively demonstrate that application of organic fertilizers and organic residues positively influence nutrient availability, with subsequent improvements in soil quality and productivity. Furthermore, the sensitivity of microbial indicators to different management practices demonstrated in this study supports their use as effective markers of ecosystem disturbance in subtropical soils.

    Acknowledgment of the gut microbiome as a vital asset to health has led to multiple studies attempting to elucidate its mechanisms of action. During the first year of life, many factors can cause fluctuation in the developing gut microbiome. Host genetics, maternal health status, mode of delivery, gestational age, feeding regime, and perinatal antibiotic usage, are known factors which can influence the development of the infant gut microbiome. Thus, the microbiome of vaginally born, exclusively breastfed infants at term, with no previous exposure to antibiotics, either directly or indirectly from the mother, is to be considered the "gold standard." Moreover, the use of prebiotics as an aid for the development of a healthy gut microbiome is equally as important in maintaining gut homeostasis. Breastmilk, a natural prebiotic source, provides optimal active ingredients for the growth of beneficial microbial species. However, early life disorders such as necrotising enterocolitis, childhood obesity, and even autism have been associated with an altered\\/disturbed gut microbiome. Subsequently, microbial therapies have been introduced, in addition to suitable prebiotic ingredients, which when administered, may aid in the prevention of a microbial disturbance in the gastrointestinal tract. The aim of this mini-review is to highlight the beneficial effects of different probiotic and prebiotic treatments in early life, with particular emphasis on the different conditions which negatively impact microbial colonisation at birth.

    Mathematical models have been widely applied to surface waters to estimate rates of settling, resuspension, flow, dispersion, and advection in order to calculate movement of particles that influence water quality. Of particular interest are the movement, survival, and persistence of microbial pathogens or their surrogates, which may contaminate recreational water, drinking water, or shellfish. Most models devoted to microbial water quality have been focused on fecal indicator organisms (FIO), which act as a surrogate for pathogens and viruses. Process-based modeling and statistical modeling have been used to track contamination events to source and to predict future events. The use of these two types of models require different levels of expertise and input; process-based models rely on theoretical physical constructs to explain present conditions and biological distribution while data-based, statistical models use extant paired data to do the same. The selection of the appropriate model and interpretation of results is critical to proper use of these tools in microbial source tracking. Integration of the modeling approaches could provide insight for tracking and predicting contamination events in real time. A review of modeling efforts reveals that process-based modeling has great promise for microbial source tracking efforts; further, combining the understanding of physical processes influencing FIO contamination developed with process-based models and molecular characterization of the population by gene-based (i.e., biological) or chemical markers may be an effective approach for locating sources and remediating contamination in order to protect human health better.

    Full Text Available The quality of water prior to its use for drinking, farming or recreational purposes must comply with several physicochemical and microbiological standards to safeguard society and the environment. In order to satisfy these standards, expensive analyses and highly trained personnel in laboratories are required. Whereas macroinvertebrates have been used as ecological indicators to review the health of aquatic ecosystems. In this research, the relationship between microbial pathogens and macrobenthic invertebrate taxa was examined in the Machangara River located in the southern Andes of Ecuador, in which 33 sites, according to their land use, were chosen to collect physicochemical, microbiological and biological parameters. Decision tree models (DTMs were used to generate rules that link the presence and abundance of some benthic families to microbial pathogen standards. The aforementioned DTMs provide an indirect, approximate, and quick way of checking the fulfillment of Ecuadorian regulations for water use related to microbial pathogens. The models built and optimized with the WEKA package, were evaluated based on both statistical and ecological criteria to make them as clear and simple as possible. As a result, two different and reliable models were obtained, which could be used as proxy indicators in a preliminary assessment of pollution of microbial pathogens in rivers. The DTMs can be easily applied by staff with minimal training in the identification of the sensitive taxa selected by the models. The presence of selected macroinvertebrate taxa in conjunction with the decision trees can be used as a screening tool to evaluate sites that require additional follow up analyses to confirm whether microbial water quality standards are met.

  19. Mechanistic links between gut microbial community dynamics, microbial functions and metabolic health

    Ha, Connie WY; Lam, Yan Y; Holmes, Andrew J

    2014-01-01

    Gut microbes comprise a high density, biologically active community that lies at the interface of an animal with its nutritional environment. Consequently their activity profoundly influences many aspects of the physiology and metabolism of the host animal. A range of microbial structural components and metabolites directly interact with host intestinal cells and tissues to influence nutrient uptake and epithelial health. Endocrine, neuronal and lymphoid cells in the gut also integrate signals from these microbial factors to influence systemic responses. Dysregulation of these host-microbe interactions is now recognised as a major risk factor in the development of metabolic dysfunction. This is a two-way process and understanding the factors that tip host-microbiome homeostasis over to dysbiosis requires greater appreciation of the host feedbacks that contribute to regulation of microbial community composition. To date, numerous studies have employed taxonomic profiling approaches to explore the links between microbial composition and host outcomes (especially obesity and its comorbidities), but inconsistent host-microbe associations have been reported. Available data indicates multiple factors have contributed to discrepancies between studies. These include the high level of functional redundancy in host-microbiome interactions combined with individual variation in microbiome composition; differences in study design, diet composition and host system between studies; and inherent limitations to the resolution of rRNA-based community profiling. Accounting for these factors allows for recognition of the common microbial and host factors driving community composition and development of dysbiosis on high fat diets. New therapeutic intervention options are now emerging. PMID:25469018

    Full Text Available Abstract Background In western Sweden, the aim was to study the associations between oral health variables and total and central adiposity, respectively, and to investigate the influence of socio-economic factors (SES, lifestyle, dental anxiety and co-morbidity. Methods The subjects constituted a randomised sample from the 1992 data collection in the Prospective Population Study of Women in Gothenburg, Sweden (n = 999, 38- > =78 yrs. The study comprised a clinical and radiographic examination, together with a self-administered questionnaire. Obesity was defined as body mass index (BMI > =30 kg/m2, waist-hip ratio (WHR > =0.80, and waist circumference >0.88 m. Associations were estimated using logistic regression including adjustments for possible confounders. Results The mean BMI value was 25.96 kg/m2, the mean WHR 0.83, and the mean waist circumference 0.83 m. The number of teeth, the number of restored teeth, xerostomia, dental visiting habits and self-perceived health were associated with both total and central adiposity, independent of age and SES. For instance, there were statistically significant associations between a small number of teeth ( Conclusions Associations were found between oral health and obesity. The choice of obesity measure in oral health studies should be carefully considered.

    Objective Promoting mental health and preventing mental health problems are important tasks for international organizations and nations. Such goals entail the establishment of active information networks and effective systems and indicators to assess the mental health of populations. This being said, there is a need in Korea develop ways to measure the state of mental health in Korea. Methods This paper reviews the mental health indicator development policies and practices of seven organizations, countries, and regions: WHO, OECD, EU, United States, Australia, UK, and Scotland. Using Delphi method, we conducted two surveys of mental health indicators for experts in the field of mental health. The survey questionnaire included 5 domains: mental health status, mental health factor, mental health system, mental health service, and quality of mental health services. We considered 124 potential mental health indicators out of more than 600 from indicators of international organizations and foreign countries. Results We obtained the top 30 mental health indicators from the surveys. Among them, 10 indicators belong to the mental health system. The most important five mental health indicators are suicide rate, rate of increase in mental disorder treatment, burden caused by mental disorders, adequacy of identifying problems of mental health projects and deriving solutions, and annual prevalence of mental disorders. Conclusion Our study provides information about the process for indicator development and the use of survey results to measure the mental health status of the Korean population. The aim of mental health indicator development is to improve the mental health system by better grasping the current situation. We suggest these mental health indicators can monitor progress in efforts to implement reform policies, provide community services, and involve users, families and other stakeholders in mental health promotion, prevention, care and rehabilitation.

    Adverse environmental exposures in early life increase the risk of chronic disease but do not attract the attention nor receive the public health priority warranted. A safe and healthy environment is essential for children's health and development, yet absent in many countries. A framework that aids in understanding the link between environmental exposures and adverse health outcomes are environmental health indicators-numerical estimates of hazards and outcomes that can be applied at a population level. The World Health Organization (WHO) has developed a set of children's environmental health indicators (CEHI) for physical injuries, insect-borne disease, diarrheal diseases, perinatal diseases, and respiratory diseases; however, uptake of steps necessary to apply these indicators across the WHO regions has been incomplete. A first indication of such uptake is the management of data required to measure CEHI. The present study was undertaken to determine whether Australia has accurate up-to-date, publicly available, and readily accessible data on each CEHI for indigenous and nonindigenous Australian children. Data were not readily accessible for many of the exposure indicators, and much of the available data were not child specific or were only available for Australia's indigenous population. Readily accessible data were available for all but one of the outcome indicators and generally for both indigenous and nonindigenous children. Although Australia regularly collects data on key national indicators of child health, development, and well-being in several domains mostly thought to be of more relevance to Australians and Australian policy makers, these differ substantially from the WHO CEHI. The present study suggests that the majority of these WHO exposure and outcome indicators are relevant and important for monitoring Australian children's environmental health and establishing public health interventions at a local and national level and collection of appropriate

    Noroviruses are the most common causative agent of viral gastroenteritis in humans, and are responsible for major foodborne illnesses in the United States. Filter-feeding molluscan shellfish exposed to sewage-contaminated waters bioaccumulate viruses, and if consumed raw, transmit the viruses to humans and cause illness. We investigated the occurrence of norovirus GI and GII and microbial indicators of fecal contamination in the eastern oysters (Crassostrea virginica) and water from commercial harvesting areas along the Louisiana Gulf Coast (January to November of 2013). Microbial indicators (aerobic plate count, enterococci, fecal coliforms, Escherichia coli, male-specific coliphages, and somatic coliphages) were detected at the densities lower than public health concerns. Only one oyster sample was positive for norovirus GII at 3.5 ± 0.2 log10 genomic equivalent copies/g digestive tissues. A stool specimen obtained from an infected individual associated with a norovirus outbreak and the suspected oysters (Cameron Parish, La., area 30, January 2013) were also analyzed. The norovirus strain in the stool belonged to GII.4 Sydney; however, the oysters were negative and could not be linked. In general, no temporal trend was observed in the microbial indicators. Low correlation among bacterial indicators was observed in oysters. Strongest correlations among microbial indicators were observed between enterococci and fecal coliforms (r = 0.63) and between enterococci and E. coli (r = 0.64) in water (P oysters (r oysters and harvest water (r ≤ 0.36, P > 0.05). Our results emphasize the need for regular monitoring of pathogenic viruses in commercial oyster harvesting areas to reduce the risks of viral gastroenteritis incidences. © 2015 Institute of Food Technologists®

    Several measures of biodiversity are commonly used to describe microbial communities, analyzed using 16S gene sequencing. A wide range of available experiments on 16S gene sequencing allows us to present a framework for a comparison of various diversity indices. The criterion for the comparison is the statistical significance of the difference in index values for microbial communities with different traits, within the same experiment. The results of the evaluation indicate that Shannon diversity is the most effective measure among the commonly used diversity indices. The results also indicate that, within the present framework, the Gini coefficient as a diversity index is comparable to Shannon diversity, despite the fact that the Gini coefficient, as a diversity estimator, is far less popular in microbiology than several other measures.

    Mediterranean rivers, which are subject to long, dry periods and heavy rainfall events, could be particularly useful for understanding future climate scenarios. This study generated microcosms that mimicked riverbank sediment resuspension into the water of a typical Mediterranean river as a consequence of heavy rainfall. The mobilization and inactivation of six fecal pollution indicators and microbial source tracking markers were evaluated. The T 90 values in the sediments were: 4 days for sorbitol-fermenting Bifidobacterium, 11 days for culturable E. coli, 36 days for bacteriophages infecting Bacteroides thetaiotaomicron strain GA17 and more than 42 days for qPCR-detected E. coli, somatic coliphages and sulfite-reducing clostridia spores. Bacteriophages and bacteria showed different resuspension and sedimentation patterns. The data obtained could be used in predictive models to assess the effects of climate change on surface water quality. Pathogen mobilization into the water column poses a risk for humans, animals and the natural environment, and breaches the One Health approach. Copyright © 2017 Elsevier Ltd. All rights reserved.

Major nutrition factors were determined by reviewing relevant epidemiological and clinical literature in nutrition and health as well as referring to reports from international expert groups, including the report from the project Nutrition and Diet for Healthy Lifestyles in Europe. The selection of factors was also based on the relative ease and cost involved for participating countries to obtain comparable and valid data. The selected factors include foods or food groups as well as individual nutrients. Biomarkers are suggested for selected nutrients that pose the greatest difficulty in obtaining valid and comparable data from dietary studies. The following list of diet indicators for health monitoring in Europe was agreed upon by the EFCOSUM group in 2001, in order of priority: vegetables, fruit, bread, fish, saturated fatty acids as percentage of energy (%E), total fat as %E, and ethanol in grams per day. Biomarkers were suggested for the following nutrients: folate, vitamin D, iron, iodine and sodium. Energy has to be assessed in order to calculate %E from total fat and saturated fatty acids.

    To achieve the hygienic safety of food waste used as animal feed, a hydrothermal treatment process of 60-110 degrees C for 10-60 min was applied on the separated food waste from a university canteen. Based on the microbial analysis of raw waste, the inactivation of hygienic indicators of Staphylococcus aureus (SA), total coliform (TC), total aerobic plate counts (TPC), and molds and yeast (MY) were analyzed during the hydrothermal process. Results showed that indicators' concentrations were substantially reduced after hydrothermal treatment, with a greater reduction observed when the waste was treated with a higher temperature and pressure and a longer ramping time. The 110 degrees C hydrothermal treatment for 60 min was sufficient to disinfect food waste as animal feed from the viewpoint of hygienic safety. Results obtained so far indicate that hydrothermal treatment can significantly decrease microbial indicators' concentrations but does not lead to complete sterilization, because MY survived even after 60 min treatment at 110 degrees C. The information from the present study will contribute to the microbial risk control of food waste-amended animal feed, to cope with legislation on food or feed safety.

    In the Mediterranean areas of Southern Spain, unsuitable agricultural practices with adverse environmental conditions (López Bermúdez and Albaladejo, 1990), have led to a permanent degradation and loss of soil fertility. This includes deterioration of the natural plant cover, which protects against erosion by contributing organic matter, the main prerequisite of ecosystem sustainability (Grace et al., 1994). Physico-chemical, microbiological and biochemical soil properties are very responsive and provide immediate and precise information on small changes occurring in soil (Dick and Tabatabai, 1993). There is increasing evidence that such parameters are also sensitive indicators of ecology stress suffered by a soil and its recovery, since microbial activity has a direct influence on the stability and fertility of ecosystems (Smith and Papendick, 1993). One method for recovering degraded soils of such semiarid regions, with their low organic matter content, is to enhance primary productivity and carbon sequestration without any additional nitrogen fertilization and preferably without incorporation of leguminous plants (Martinez Mena et al., 2008). Carbon rich materials can sustain microbial activity and growth, thus enhancing biogeochemical nutrient cycles (Pascual et al., 1997). The present study is focused in the role of physico-chemical and microbial soil properties in Mediterranean environment, in terms of in situ and ex situ microbial transformation of soil carbon and nitrogen, in order to characterise the key soil microbial activities which could strongly affect carbon and nitrogen turnover in soil and hereby soil fertility and soil organic matter "quality". These microbial activities could at unsuitable agricultural practices with adverse environmental conditions induce unfavourable hydrologycal tempo-spatial response. The final results shown modifications in the soil properties studied with the increasing of the aridity. Such changes suppose the soil

    The significance of contact with microbes in early life for subsequent health has been the subject of intense research during the last 2 decades. Disturbances in the establishment of the indigenous intestinal microbiome caused by cesarean section delivery or antibiotic exposure in early life have been linked to the risk of immune-mediated and inflammatory conditions such as atopic disorders, inflammatory bowel disease and obesity later in life. Distinct microbial populations have recently been discovered at maternal sites including the amniotic cavity and breast milk, as well as meconium, which have previously been thought to be sterile. Our understanding of the impact of fetal microbial contact on health outcomes is still rudimentary. Breast milk is known to modulate immune and metabolic programming. The breast milk microbiome is hypothesized to guide infant gut colonization and is affected by maternal health status and mode of delivery. Immunomodulatory factors in breast milk interact with the maternal and infant gut microbiome and may mediate some of the health benefits associated with breastfeeding. The intimate connection between the mother and the fetus or the infant is a potential target for microbial therapeutic interventions aiming to support healthy microbial contact and protect against disease.

    Health Information Systems (HISs) are expected to have a positive impact on quality and efficiency of health care. Rapid investment in and diffusion of HISs has increased the importance of monitoring the adoption and impacts of them in order to learn from the initiatives, and to provide decision makers evidence on the role of HISs in improving health care. However, reliable and comparable data across initiatives in various countries are rarely available. A four-phase approach is used to compare different HIS indicator methodologies in order to move ahead in defining HIS indicators for monitoring effects of HIS on health care performance. Assessed approaches are strong on different aspects, which provide some opportunities for learning across them but also some challenges. As yet, all of the approaches do not define goals for monitoring formally. Most focus on health care structural and process indicators (HIS availability and intensity of use). However, many approaches are generic in description of HIS functionalities and context as well as their impact mechanisms on health care for HIS benchmarking. The conclusion is that, though structural and process indicators of HIS interventions are prerequisites for monitoring HIS impacts on health care outputs and outcomes, more explicit definition is needed of HIS contexts, goals, functionalities and their impact mechanisms in order to move towards common process and outcome indicators. A bottom-up-approach (participation of users) could improve development and use of context-sensitive HIS indicators.

    Microbial contamination of recreational beaches is often at its worst after heavy rainfall events due to storm floods that carry fecal matter and other pollutants from the watershed. Similarly, overflows of untreated sewage from combined sewerage systems may discharge directly into coastal water or via rivers and streams. In order to understand the effect of rainfall events, wind-directions and tides on the recreational water quality, GEMSS, an integrated 3D hydrodynamic model was applied to assess the spreading of Escherichia coli (E. coli) at the Sandvika beaches, located in the Oslo fjord. The model was also used to theoretically investigate the effect of discharges from septic tanks from boats on the water quality at local beaches. The model make use of microbial decay rate as the main input representing the survival of microbial pathogens in the ocean, which vary widely depending on the type of pathogen and environmental stress. The predicted beach water quality was validated against observed data after a heavy rainfall event using Nash-Sutcliffe coefficient (E) and the overall result indicated that the model performed quite well and the simulation was in - good agreement with the observed E. coli concentrations for all beaches. The result of this study indicated that: 1) the bathing water quality was poor according to the EU bathing water directive up to two days after the heavy rainfall event depending on the location of the beach site. 2) The discharge from a boat at 300-meter distance to the beaches slightly increased the E. coli levels at the beaches. 3) The spreading of microbial pathogens from its source to the different beaches depended on the wind speed and the wind direction.

    Contamination of aquatic ecosystems by human and animal wastes is a global concern for water quality. Disclosing fate and transport processes of fecal indicator organism (FIO) in large water bodies is a big challenge due to material intensive and time consuming methods used in microbiological water quality monitoring. In respect of utilization of large surface water resources there is a dearth of rapid microbiological methods that allow a near-real time health related water quality monitoring to be implemented into early warning systems. The detection of enzymatic activities has been proposed as a rapid surrogate for microbiological pollution monitoring of water and water resources (Cabral, 2010; Farnleitner et al., 2001, 2002). Methods such as the beta-D-Glucuronidase assay (GLUC), targeting FIO such as E. coli, were established. New automated enzymatic assays have been implemented during the last years into on-site monitoring stations, ranging from ground- to surface waters (Ryzinska-Paier et al., 2014; Stadler et al., 2017, 2016). While these automated enzymatic methods cannot completely replace assays for culture-based FIO enumeration, they yielded significant information on pollution events and temporal dynamics on a catchment specific basis, but were restricted to stationary measurements. For the first time we conducted ship-borne and automated measurements of enzymatic GLUC activity on large fresh water bodies, including the Columbia River, the Mississippi River and Lake Mendota. Not only are automated enzymatic assays technically feasible from a mobile vessel, but also can be used to localize point sources of potential microbial fecal contamination, such as tributaries or storm drainages. Spatial and temporal patterns of enzymatic activity were disclosed and the habitat specific correlation with microbiological standard assays for FIO determined due to reference samples.

    There are few methods available for broadly assessing microbial community metabolism directly within a groundwater environment. In this study, hydrogen consumption rates were estimated from in situ injection/withdrawal tests conducted in two geochemically varying, contaminated aquifers as an approach towards developing such a method. The hydrogen consumption first-order rates varied from 0.002 nM h-1 for an uncontaminated, aerobic site to 2.5 nM h-1 for a contaminated site where sulfate reduction was a predominant process. The method could accommodate the over three orders of magnitude range in rates that existed between subsurface sites. In a denitrifying zone, the hydrogen consumption rate (0.02 nM h-1) was immediately abolished in the presence of air or an antibiotic mixture, suggesting that such measurements may also be sensitive to the effects of environmental perturbations on field microbial activities. Comparable laboratory determinations with sediment slurries exhibited hydrogen consumption kinetics that differed substantially from the field estimates. Because anaerobic degradation of organic matter relies on the rapid consumption of hydrogen and subsequent maintenance at low levels, such in situ measures of hydrogen turnover can serve as a key indicator of the functioning of microbial food webs and may be more reliable than laboratory determinations. ?? 2007 Federation of European Microbiological Societies.

    Full Text Available Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertilizers, were considered. The activities of soil enzymes including dehydrogenase, β-glucosidase, arylsulfatase, urease, alkaline and acid phosphatases were used as indicators of important microbial mediated functions and the soil chemical properties were measured in the soils applied with organic or inorganic fertilizer for 10 years. Fatty acid methyl ester analysis was applied to determine the soil microbial community composition. Relatively higher microbial community richness and enzyme activities were found in the organic fertilizers applied soils as compared to the inorganic fertilizers applied soils. Principal component analysis explained the positive influence of organic fertilizers on the microbial community. The application of organic fertilizers can be a better alternative compared to inorganic fertilizers for the long-term health and security of urban agriculture.

  4. Linking the Gut Microbial Ecosystem with the Environment: Does Gut Health Depend on Where We Live?

    2017-10-01

    Full Text Available Global comparisons reveal a decrease in gut microbiota diversity attributed to Western diets, lifestyle practices such as caesarian section, antibiotic use and formula-feeding of infants, and sanitation of the living environment. While gut microbial diversity is decreasing, the prevalence of chronic inflammatory diseases such as inflammatory bowel disease, diabetes, obesity, allergies and asthma is on the rise in Westernized societies. Since the immune system development is influenced by microbial components, early microbial colonization may be a key factor in determining disease susceptibility patterns later in life. Evidence indicates that the gut microbiota is vertically transmitted from the mother and this affects offspring immunity. However, the role of the external environment in gut microbiome and immune development is poorly understood. Studies show that growing up in microbe-rich environments, such as traditional farms, can have protective health effects on children. These health-effects may be ablated due to changes in the human lifestyle, diet, living environment and environmental biodiversity as a result of urbanization. Importantly, if early-life exposure to environmental microbes increases gut microbiota diversity by influencing patterns of gut microbial assembly, then soil biodiversity loss due to land-use changes such as urbanization could be a public health threat. Here, we summarize key questions in environmental health research and discuss some of the challenges that have hindered progress toward a better understanding of the role of the environment on gut microbiome development.

The health and quality indicators are a set of measurements (physical, chemical and biological properties that pretend to establish quality standards for this resource; the enzymatic activity is placed inside this set because of its close relationship with the other properties and because of its sensibleness to the changes due to handling and use. The present review pretends to illustrate how the tracking of the biological catalysis of the soil through uses and alterations that an ecosystem may suffer, may supply information for the understanding of how the processes responsible for the maintenance of functions such as biomass production, pollutant remediation and cycling of nutrients, suffer changes and if these are positive, negative or iterative.

    The pioneer microbiota of the neonatal gut are essential for gut maturation, and metabolic and immunologic programming. Recent research has shown that early bacterial colonization may impact the occurrence of disease later in life (microbial programming). Despite early conflicting evidence, it has long been considered that the womb is a sterile environment and human microbial colonization begins at birth. In the last few years, several findings have reiterated the presence of microbes in infant first stool (meconium) and pointed to the existence of in utero microbial colonization of the infant gut. The dominant bacterial taxa detected in meconium specimens belong to the Enterobacteriaceae family (Escherichia genus) and lactic acid bacteria (notably members of the genera Leuconostoc, Enterococcus, and Lactococcus). Maternal atopy promotes dominance of Enterobacteriaceae in newborn meconium, which in turn may lead to respiratory problems in the infant. This microbial interaction with the host immune system may in fact, originate during fetal life. Our review evaluates the evidence for an intrauterine origin of meconium microbiota, their composition and influences, and potential clinical implications on infant health. © 2015 Wiley Periodicals, Inc.

    2011-05-01

    In the present study we evaluated the degree of microbial water pollution along the coast line between Brindisi and Santa Maria di Leuca (Southern Adriatic Sea) as well as the culturable heterotrophic bacteria abundances and biodiversity in relation to the microbiological quality of the water. A total of 3773 colonies were isolated, subcultured and identified by several morphological, cultural and biochemical methods including the standardized API 20 E and API 20 NE tests. Along the examined coastal tract the microbial pollution indicators were always below the tolerance limits for bathing waters defined by the CEE directive, suggesting a good sanitary quality. Concerning culturable heterotrophic bacteria, different temporal density trends were observed in the four sites in relation to their geographical position. A positive relationship between the bacterial abundances and the temperature was observed in S. Cataldo and Otranto. The culturable bacterial community was mainly composed of the genera Aeromonas, Pseudomonas, Photobacterium and Flavobacterium. The Enterobacteriaceae family represented a conspicuous component of the bacterial community too. Bacilli were predominant among the Gram-positive bacteria. Of interest is the isolation of yeasts (2% at the surface and 1% at the bottom) taking into account their capability of biodegradation of various materials. Because of the low level of microbial pollution recorded, our results are indicative of the natural variation and diversity of the culturable bacterial community in such an oligotrophic ecosystem and could represent a good point of comparison with other ecosystems as well as a baseline for long term studies aimed to evaluate the effects of environmental fluctuations and human impacts on this aspect of biodiversity in coastal areas.

    Evidence-based political measures need reliable information about the health status of a population and the determinants affecting health. Here, environment and health indicators can provide helpful additional insights. This article provides an overview of existing indicators in the field of environment and health. There are single indicators and indicator sets describing solely the environment or health as well as some indicators integrating both aspects. The indicator sets cover classical epidemiological indicators but also summary measures of population health, which combine mortality and morbidity as well as simple descriptions of the exposure towards environmental risks. The indicator sets mostly cover water and air quality related aspects. For some of the indicators their influence on health is also presented. Furthermore, environment related health indicators are part of sustainability indicator sets. There are indicators on the international, European, national, and municipal level. All indicator sets aim to support policy-making by advising on measures and setting priorities in the area of environment and health protection. However not all indicators reflect the effect of the environment on health adequately. Therefore, further development of the existing indicators is necessary to reflect current progress (e. g. political needs) and to include new scientific evidence in the field of environment and health. A continuous provision, review, and interpretation of meaningful indicators is required to identify trends and to react to these in order to protect the environment and health. This is necessary to adequately pursue the precautionary principle.

    Maintaining good soil productivity in rice paddies is important for global food security. Numerous methods have been developed to evaluate paddy soil productivity (PSP), most based on soil physiochemical properties and relatively few on biological indices. Here, we used a long-term dataset from experiments on paddy fields at eight county sites and a short-term dataset from a single field experiment in southern China, and aimed at quantifying relationships between PSP and the ratios of carbon (C) to nutrients (N and P) in soil microbial biomass (SMB). In the long-term dataset, SMB variables generally showed stronger correlations with the relative PSP (rPSP) compared to soil chemical properties. Both correlation and variation partitioning analyses suggested that SMB N, P and C:N ratio were good predictors of rPSP. In the short-term dataset, we found a significant, negative correlation of annual rice yield with SMB C:N (r = -0.99), confirming SMB C:N as a robust indicator for PSP. In treatments of the short-term experiment, soil amendment with biochar lowered SMB C:N and improved PSP, while incorporation of rice straw increased SMB C:N and reduced PSP. We conclude that SMB C:N ratio does not only indicate PSP but also helps to identify management practices that improve PSP.

    2006-11-01

    Where legal systems allow therapeutic abortion to preserve women's mental health, practitioners often lack access to mental health professionals for making critical diagnoses or prognoses that pregnancy or childcare endangers patients' mental health. Practitioners themselves must then make clinical assessments of the impact on their patients of continued pregnancy or childcare. The law requires only that practitioners make assessments in good faith, and by credible criteria. Mental disorder includes psychological distress or mental suffering due to unwanted pregnancy and responsibility for childcare, or, for instance, anticipated serious fetal impairment. Account should be taken of factors that make patients vulnerable to distress, such as personal or family mental health history, factors that may precipitate mental distress, such as loss of personal relationships, and factors that may maintain distress, such as poor education and marginal social status. Some characteristics of patients may operate as both precipitating and maintaining factors, such as poverty and lack of social support.

  13. Metagenomic analysis indicates Epsilonproteobacteria as a potential cause of microbial corrosion in pipelines injected with bisulfite

    Full Text Available Sodium bisulfite (SBS is used as an oxygen scavenger to decrease corrosion in pipelines transporting brackish subsurface water used in the production of bitumen by steam-assisted gravity drainage. Sequencing 16S rRNA gene amplicons has indicated that SBS addition increased the fraction of the sulfate-reducing bacteria (SRB Desulfomicrobium, as well as of Desulfocapsa, which can also grow by disproportionating sulfite into sulfide, sulfur and sulfate. SRB use cathodic H2, formed by reduction of aqueous protons at the iron surface, or use low potential electrons from iron and aqueous protons directly for sulfate reduction. In order to reveal the effects of SBS treatment in more detail, metagenomic analysis was performed with pipe-associated solids (PAS scraped from a pipe section upstream (PAS-616P and downstream (PAS-821TP of the SBS injection point. A major SBS-induced change in microbial community composition and in affiliated hynL genes for the large subunit of [NiFe] hydrogenase was the appearance of sulfur-metabolizing Epsilonproteobacteria of the genera Sulfuricurvum and Sulfurovum. These are chemolithotrophs, which oxidize sulfide or sulfur with O2 or reduce sulfur with H2. Because O2 was absent, this class likely catalyzed reduction of sulfur (S0 originating from the metabolism of bisulfite with cathodic H2 (or low potential electrons and aqueous protons originating from the corrosion of steel (Fe0. Overall this accelerates reaction of of S0 and Fe0 to form FeS, making this class a potentially powerful contributor to microbial corrosion. The PAS-821TP metagenome also had increased fractions of Deltaproteobacteria including the SRB Desulfomicrobium and Desulfocapsa. Altogether, SBS increased the fraction of hydrogen-utilizing Delta- and Epsilonproteobacteria in brackish-water-transporting pipelines, potentially stimulating anaerobic pipeline corrosion if dosed in excess of the intended oxygen scavenger function.

    Full Text Available The Yellow River is the most important water resource in northern China. In the recent past, heavy metal contamination has become severe due to industrial processes and other anthropogenic activities. In this study, riparian soil samples with varying levels of chromium (Cr pollution severity were collected along the Gansu industrial reach of the Yellow River, including samples from uncontaminated sites (XC, XGU, slightly contaminated sites (LJX, XGD, and heavily contaminated sites (CG, XG. The Cr concentrations of these samples varied from 83.83 mg⋅kg-1 (XGU to 506.58 mg⋅kg-1 (XG. The chromate [Cr (VI] reducing ability in the soils collected in this study followed the sequence of the heavily contaminated > slightly contaminated > the un-contaminated. Common Cr remediation genes chrA and yieF were detected in the XG and CG samples. qRT-PCR results showed that the expression of chrA was up-regulated four and threefold in XG and CG samples, respectively, whereas the expression of yieF was up-regulated 66- and 7-fold in the same samples after 30 min treatment with Cr (VI. The copy numbers of chrA and yieF didn’t change after 35 days incubation with Cr (VI. The microbial communities in the Cr contaminated sampling sites were different from those in the uncontaminated samples. Especially, the relative abundances of Firmicutes and Bacteroidetes were higher while Actinobacteria was lower in the contaminated group than uncontaminated group. Further, potential indicator species, related to Cr such as Cr-remediation genera (Geobacter, PSB-M-3, Flavobacterium, and Methanosarcina; the Cr-sensitive genera (Skermanella, Iamia, Arthrobacter, and Candidatus Nitrososphaera were also identified. These data revealed that Cr shifted microbial composition and function. Further, Cr (VI reducing ability could be related with the expression of Cr remediation genes.

    To improve food safety on farms, it is critical to quantify the impact of environmental microbial contamination sources on fresh produce. However, studies are hampered by difficulties achieving study designs with powered sample sizes to elucidate relationships between environmental and produce contamination. Our goal was to quantify, in the agricultural production environment, the relationship between microbial contamination on hands, soil, and water and contamination on fresh produce. In 11 farms and packing facilities in northern Mexico, we applied a matched study design: composite samples ( n = 636, equivalent to 11,046 units) of produce rinses were matched to water, soil, and worker hand rinses during two growing seasons. Microbial indicators (coliforms, Escherichia coli , Enterococcus spp., and somatic coliphage) were quantified from composite samples. Statistical measures of association and correlations were calculated through Spearman's correlation, linear regression, and logistic regression models. The concentrations of all microbial indicators were positively correlated between produce and hands (ρ range, 0.41 to 0.75; P contamination of soil and water and contamination of produce. This methodology provides a foundation for future field studies, and results highlight the need for interventions surrounding farmworker hygiene and sanitation to reduce microbial contamination of farmworkers' hands. IMPORTANCE This study of the relationships between microbes on produce and in the farm environment can be used to support the design of targeted interventions to prevent or reduce microbial contamination of fresh produce with associated reductions in foodborne illness.

    2017-06-01

    Full Text Available Several studies have noted that treated and untreated wastewaters are primary contributors of a variety of pathogenic microorganisms to the aquatic ecosystem. Conventional wastewater treatment may not be sufficient to achieve microbiologically safe effluent to be discharged into natural waters or reused, thus requiring wastewater effluents to be disinfected. In recent years, peracetic acid (PAA has been adopted as a disinfectant for wastewater effluents. The aim of this study was to evaluate the disinfection efficiency of PAA at low doses (range 0.99–2.10 mg/L against microbial indicators and pathogenic bacteria in a municipal wastewater plant. Samples of untreated sewage and effluents before and after PAA treatment were collected seasonally for 1 year and were analysed for pathogenic Campylobacter, Salmonella spp., E. coli O157:H7 and E. coli virulence genes using molecular methods; moreover, the detection of specific microbial indicators (E. coli, faecal coliforms, enterococci, C. perfringens and Salmonella spp. were carried out using culturing methods. Salmonella spp. DNA was found in all untreated sewage and effluent before PAA treatment, whereas it was recovered in 50% of the samples collected after PAA treatment. Although E. coli O157:H7 was never identified, the occurrence of Shiga-like toxin I amplicons was identified in 75% of the untreated sewage samples, in 50% of the effluents assayed before PAA treatment, and in 25% of the effluents assayed after PAA treatment, whereas the stx2 gene was never found. Campylobacter coli was only detected in one effluent sample before PAA treatment. In the effluents after PAA treatment, a lower load of indicator bacteria was observed compared to the effluents before treatment. The results of this study highlight that the use of low doses of PAA seems to lead to an improvement of the microbiological quality of the effluent, although it is not sufficient to guarantee its suitability for irrigation

    Full Text Available Intercropping forest plantations of Eucalyptus with nitrogen-fixing trees can increase soil N inputs and stimulate soil organic matter (OM cycling. However, microbial indicators and their correlation in specific fractions of soil OM are unclear in the tropical sandy soils. Here, we examined the microbial indicators associated with C and N in the soil resulting from pure and intercropped Eucalyptus grandis and Acacia mangium plantations. We hypothesized that introduction of A. mangium in a Eucalyptus plantation promotes changes in microbial indicators and increases C and N concentrations on labile fractions of the soil OM, when compared to pure eucalyptus plantations. We determined the microbial and enzymatic activity, and the potential for C degradation by the soil microbial community. Additionally, we evaluated soil OM fractions and litter parameters. Soil (0–20 cm and litter samples were collected at 27 and 39 months after planting from the following treatments: pure E. grandis (E and A. mangium (A plantations, pure E. grandis plantations with N fertilizer (E+N and an E. grandis, and A. mangium intercropped plantations (E+A. The results showed that intercropped plantations (E+A increase 3, 45, and 70% microbial biomass C as compared to A, E+N, and E, at 27 months after planting. The metabolic quotient (qCO2 showed a tendency toward stressful values in pure E. grandis plantations and a strong correlation with dehydrogenase activity. A and E+A treatments also exhibited the highest organic fractions (OF and C and N contents. A canonical redundancy analysis revealed positive correlations between microbial indicators of soil and litter attributes, and a strong effect of C and N variables in differentiating A and E+A from E and E+N treatments.

    Many changes have been made in different sciences by developing and advancing information and communication technology in last two decades. E-health is a very broad term that includes many different activities related to the use of electronic devices, software as well as hardware in health organizations. The aim of this study is comparing electronic health indicators in the selected countries and discussion on the best indicators. This study has chosen 12 countries randomly based on the regional division of the WHO. The relevant numbers of health indicators and general indicators and information technology indicators are extracted of these countries. We use data from the Bitarf's comparative study, which is conducted by the Iranian Supreme Council of Information Technology in 2007. By using Pearson correlation test, the relations between health general indicators and IT indicators are studied. Data was analyzed based on the research objectives using SPSS software and in accordance with research questions Pearson correlation test were used. The findings show that there is a positive relation between indicators related to IT and "Total per capita health, healthy life expectancy, percent literacy". Furthermore, there is a mutual relation between IT indicators and "mortality indicator". This study showed differences between selective indicators among different countries. The modern world, with its technological advances, is not powerless in the face of these geographic and health disparity challenges. Researchers must not rely on the available indicators. They must consider indicators like e-business companies, electronic data internet, medical supplies, health electronic record, health information system, etc., In future, continuous studies in this field, to provide the exact and regular reports of amount of using of these indicators through different countries must be necessary.

    Fecal coliforms are indicators for disease-causing pathogens. The United States Environmental Protection Agency (US. EPA) recommends the use of E. coli and Enterococci because they are highly correlated with pathogenic organisms in recreational waters. This standard method helps to determine the overall water quality and the potential health risks. Studies have shown that it is difficult to estimate the exact sources of fecal contamination because both human and certain animal species contain E. coli and Enterococci in their waste. Certain strains of E. coli and Enterococci are also able to survive outside of their hosts, which should not be the case for an appropriate fecal indicator. As a result, microbial source tracking (MST) studies use gene specific markers to identify the possible contributors to water pollution whether human or animal. Trail Creek is a second-order stream located in Athens-Clarke County, GA. The 33-km2 watershed is approximately 64% forests, 18% pastures and 16% residential communities. Trail Creek is on the TMDL list and an extended study on the relationships between the different factors causing elevated fecal bacteria is needed. Synoptic sampling events were conducted during baseflow conditions at six locations. Storm sampling events (> 8 mm) were captured using automated samplers at two locations. These samplers were equipped with pressure transducers which record stage at 30-minute intervals. The samples were analyzed for fecal coliform, E. Coli and Enterococci. Water quality parameters including temperature, specific conductance, dissolved oxygen, pH, and turbidity were also recorded. Relationships between the parameters and fecal indicator bacteria show inconsistent patterns and high variability. Using quantitative PCR and MST techniques, the human specific marker (HF183) and ruminant marker (Rum2Bac) were used to identify the fecal sources in both baseflow and storm samples. The presence and abundance of the different markers at

    Combined sewer overflows (CSOs) degrade water quality and end-of-pipe treatment is one potential solution for retrofitting this outdated infrastructure. The goal of this research was to evaluate peracetic acid (PAA) as a disinfectant for CSOs using viability based molecular methods for antibiotic resistance genes (ARGs), indicator organism marker gene BacHum, and 16S rRNA genes. Simulated CSO effluent was prepared using 23-40% wastewater, representing the higher end of the range of wastewater concentrations reported in CSO effluent. PAA residual following disinfection was greatest for samples with the lowest initial COD. Treatment of simulated CSO effluent (23% wastewater) with 100 mg∙min/L PAA (5 mg/L PAA, 20 min) was needed to reduce viable cell sul 1, tet (G), and BacHum (1.0±0.63-3.2±0.25-log) while 25 to 50 mg•min/L PAA (5 mg/L PAA, 5-10 min) was needed to reduce viable cell loads (0.62±0.56-1.6±0.08-log) in 40% wastewater from a different municipal treatment plant. Increasing contact time after the initial decrease in viable cell gene copies did not significantly improve treatment. A much greater applied Ct of 1200 mg∙min/L PAA (20 mg/L PAA, 60 min) was required for significant log reduction of 16S rRNA genes (3.29±0.13-log). No significant losses of mex B were observed during the study. Data were fitted to a Chick-Watson model and resulting inactivation constants for sul 1 and tet (G) > BacHum > 16S rRNA. Amplicon sequencing of the 16S rRNA gene indicated the initial viable and total microbial communities were distinct and that treatment with PAA resulted in marked increases of the relative abundance of select phyla, particularly Clostridia which increased by 1-1.5 orders of magnitude. Results confirm that membrane disruption is a mechanism for PAA disinfection and further treatment is needed to reduce total ARGs in CSO effluent.

The experiment consisted of combinations of synthetic nitrogen (N, vinasse (V; a liquid waste from ethanol production, and sugarcane-straw blankets. Increases in CO2-C and N2O-N emissions were identified shortly after the addition of both N and V to the soils, thus increasing MB nitrogen (MB-N and decreasing MB carbon (MB-C in the N+V-amended soils and altering soil chemical factors that were correlated with the MB. Across 57 soil metagenomic datasets, Actinobacteria (31.5%, Planctomycetes (12.3%, Deltaproteobacteria (12.3%, Alphaproteobacteria (12.0% and Betaproteobacteria (11.1% were the most dominant bacterial groups during the experiment. Differences in relative abundance of metagenomic sequences were mainly revealed for Acidobacteria, Actinobacteria, Gammaproteobacteria and Verrucomicrobia with regard to N+V fertilization and straw retention. Differential abundances in bacterial groups were confirmed using 16S rRNA gene-targeted phylum-specific primers for real-time PCR analysis in all soil samples, whose results were in accordance with sequence data, except for Gammaproteobacteria. Actinobacteria were more responsive to straw retention with Rubrobacterales, Bifidobacteriales and Actinomycetales related to the chemical factors of N+V-amended soils. Acidobacteria subgroup 7 and Opitutae, a verrucomicrobial class, were related to the chemical factors of soils without straw retention as a surface blanket.

    Comparison of published data and health indices from different countries with different health systems is subject to many pitfalls. Comparison of national expenditure for health care based on purchasing power of the currency may be misleading if the purchasing power of the health services is ignored. Comparisons may also be misleading if they ignore national geographic and demographic structures. Government and health authorities often quote different sets of data and use different terminology and definitions. This article stresses the disparity in the definition of medical manpower and points out differences relating to ratios of manpower to population and to per capita spending. Also addressed is the importance of the qualitative and value aspects of health systems not usually involved in comparison of international health indices. In conclusion, safety measures and precautions such as choosing the right index for the right purpose, adjustment of indices to the purchasing power parity of health, demographics, etc., should be used when conducting health care analyses.

    Full Text Available Pasture degradation is a concern, especially in susceptible sandy soils for which strategies to recover them must be developed. Microbiological and biochemical soil health indicators are useful in the guindace of soil management practices and sustainable soil use. We assessed the success of threePanicum maximum Jacq. cultivars in the reclamation of a pasture in a sandy Typic Acrudox in the northwest of the state of Paraná, Brazil, based on soil health indicators. On a formerly degraded pasture withUrochloa brizantha (Hochst. ex A. Rich. R.D. Webster, a trial with threeP. maximum (cv. Massai, Tanzânia, or Mombaça was conducted. Lime and phosphate were applied at set-up, and mineral N and K as topdressing. A remnant of degraded pasture adjacent to the trial was used as control. Twenty-three chemical, physical, microbiological and biochemical attributes were assessed for the 0-10 cm topsoil. The procedures for reclamation improved most of the indicators of soil health in relation to the degraded pasture, such as soil P, mineral N, microbial biomass C, ammonification rate, dehydrogenase activity and acid phosphatase. CO2 evolution decreased, whereas microbial biomass C increased in the pasture under reclamation, resulting in a lower metabolic quotient (qCO2 that points to a decrease in metabolic stress of the microbial community. The reclamation of the pasture withP. maximum, especially cv. Mombaça, were evidenced by improvements in the microbiological and biochemical soil health indicators, showing a recovery of processes related to C, N and P cycling in the soil.

    Bacterial indicators are used to indicate increased health risk from pathogens and to make beach closure and advisory decisions; however, beaches are seldom monitored for the pathogens themselves. Studies of sources and types of pathogens at beaches are needed to improve estimates of swimming-associated health risks. It would be advantageous and cost-effective, especially for studies conducted on a regional scale, to use a method that can simultaneously filter and concentrate all classes of pathogens from the large volumes of water needed to detect pathogens. In seven recovery experiments, stock cultures of viruses and protozoa were seeded into 10-liter lake water samples, and concentrations of naturally occurring bacterial indicators were used to determine recoveries. For the five filtration methods tested, the highest median recoveries were as follows: glass wool for adenovirus (4.7%); NanoCeram for enterovirus (14.5%) and MS2 coliphage (84%); continuous-flow centrifugation (CFC) plus Virocap (CFC+ViroCap) for Escherichia coli (68.3%) and Cryptosporidium (54%); automatic ultrafiltration (UF) for norovirus GII (2.4%); and dead-end UF for Enterococcus faecalis (80.5%), avian influenza virus (0.02%), and Giardia (57%). In evaluating filter performance in terms of both recovery and variability, the automatic UF resulted in the highest recovery while maintaining low variability for all nine microorganisms. The automatic UF was used to demonstrate that filtration can be scaled up to field deployment and the collection of 200-liter lake water samples.

    Mining of sulfide ore deposits containing metalloids, such as antimony and arsenic, has introduced serious soil contamination around the world, posing severe threats to food safety and human health. Hence, it is important to understand the behavior and composition of the microbial communities that control the mobilization or sequestration of these metal(loid)s. Here, we selected two sites in Southwest China with different levels of Sb and As contamination to study interactions among various Sb and As fractions and the soil microbiota, with a focus on the microbial response to metalloid contamination. Comprehensive geochemical analyses and 16S rRNA gene amplicon sequencing demonstrated distinct soil taxonomic inventories depending on Sb and As contamination levels. Stochastic gradient boosting indicated that citric acid extractable Sb(V) and As(V) contributed 5% and 15%, respectively, to influencing the community diversity. Random forest predicted that low concentrations of Sb(V) and As(V) could enhance the community diversity but generally, the Sb and As contamination impairs microbial diversity. Co-occurrence network analysis indicated a strong correlation between the indigenous microbial communities and various Sb and As fractions. A number of taxa were identified as core genera due to their elevated abundances and positive correlation with contaminant fractions (total Sb and As concentrations, bioavailable Sb and As extractable fractions, and Sb and As redox species). Shotgun metagenomics indicated that Sb and As biogeochemical redox reactions may exist in contaminated soils. All these observations suggest the potential for bioremediation of Sb- and As-contaminated soils.

    Socio-medical indicators developed by WHO for monitoring progress towards Health-for-All have been adapted to reveal, clearly and objectively, the devastating impact of state planning based on an outmoded immoral and unscientific philosophy of race superiority in South Africa on the health of the disenfranchised majority within the context of social and economic discrimination; Health policy indicators confirm that the government is committed to three options (Bantustans, A New Constitution, and A Health Services Facilities Plan) all of which are inconsistent with the attainment of Health-for-All; Social and economic indicators reveal gross disparities between African, Coloured, Indian, and White living and working conditions; Provision of health care indicators show the overwhelming dominance of high technology curative medical care consuming about 97 percent of the health budget with only minor shifts towards community-based comprehensive care; and Health status indicators illustrate the close nexus between privilege, dispossession and disease with Whites falling prey to health problems related to affluence and lifestyle, while Africans, Coloureds, and Indians suffer from disease due to poverty. All four categories of the indicator system reveal discrepancies which exist between Black and White, rich and poor, urban and rural. To achieve the social goal of Health-for-All requires a greater measure of political commitment from the state. We conclude that it is debatable whether a system which maintains race discrimination and exploitation can in fact be adapted to provide Health-for-All.

  19. 15N indicates an active N-cycling microbial community in low carbon, freshwater sediments.

    Earth's large lakes are unique aquatic ecosystems, but we know little of the microbial life driving sedimentary biogeochemical cycles and ultimately the isotopic record. In several of these large lakes, water column productivity is constrained by element limitation, such as phosphorus and iron, creating oligotrophic water column conditions that drive low organic matter content in sediments. Yet, these sediments are biogeochemically active and have been shown to have oxygen consumption rates akin to pelagic ocean sediments and complex sulfur cycling dynamics. Thus, large oligotrophic lakes provide unique and interesting biogeochemical contrast to highly productive freshwater and coastal marine systems. Using Lake Superior as our study site, we found microbial community structure followed patterns in bulk sediment carbon and nitrogen concentrations. These observed patterns were loosely driven by land proximity, as some stations are more coastal and have higher rates of sedimentation, allochthonous carbon inputs and productivity than pelagic sites. Interestingly, upper sediment carbon and nitrogen stable isotopes were quite different from water column. Sediment carbon and nitrogen isotopes correlated significantly with microbial community structure. However, 15N showed much stronger correlation than 13C, and became heavier with core depth. Coinciding with the increase in 15N values, we see evidence of both denitrification and anammox processes in 16S rRNA gene libraries and metagenome assembled genomes. Given that microorganisms prefer light isotopes and that these N-cycling processes both contribute to N2 production and efflux from the sediment, the increase in 15N with sediment depth suggests microbial turnover. Abundance of these genomes also varies with depth suggesting these novel microorganisms are partitioning into specific sediment geochemical zones. Additionally, several of these genomes contain genes involved in sulphur cycling, suggesting a dual

    Full Text Available Aim: The aim of the present study was the evaluation of non-microbial salivary caries activity parameters and salivary biochemical indicators in predicting dental caries. Materials and Methods: The present study was carried out on 60 children, aged 4-6 years, selected from the schools of Panchkula district, Haryana, on the basis of their caries status. Level of hydration, flow rate, pH, buffering capacity, relative viscosity, calcium, phosphorus and alkaline phosphatase levels in caries-free and caries-active children were evaluated. Results: Results showed that 90% of subjects in the caries-free group and 30% of subjects in the caries-active group had normal level of hydration value of less than 60 s and the difference was found to be statistically very highly significant. Normal flow rate of stimulated saliva was found in 90% of the subjects in caries-free group and 33.3% subjects in the caries active group and difference was found to be statistically very highly significant. Adequate salivary pH was found in 100% subjects in caries-free group and 30% in caries-active group and the difference was statistically very highly significant. Conclusion: To conclude, within limitations of this study, it became clear that normal level of hydration and higher values for flow rate, pH, buffering capacity of saliva lead to good oral health and a reduced caries occurrence. Increased salivary viscosity plays a role in increasing caries incidence. Salivary biochemical indicators like calcium, phosphorus and alkaline phosphatase also play their respective role in determining caries susceptibility of an individual. These salivary parameters can be used as diagnostic tool for caries risk assessment.

    Climate change scenarios predict an increase of intense rainfall events in summer in Western Europe. Current urban drainage systems cannot cope with such intense precipitation events. Cities are constructing stormwater storage facilities to prevent pluvial flooding. Combining storage with other functions, such as recreation, may lead to exposure to contaminants. This study assessed the microbial quality of rainwater collected in a water plaza and the health risks associated with recreational exposure. The water plaza collects street run-off, diverges first flush to the sewer system and stores the rest of the run-off in the plaza as open water. Campylobacter, Cryptosporidium and Legionella pneumophila were the pathogens investigated. Microbial source tracking tools were used to determine the origin (human, animal) of the intestinal pathogens. Cryptosporidium was not found in any sample. Campylobacter was found in all samples, with higher concentrations in samples containing human Bacteroides than in samples with zoonotic contamination (15 vs 3.7 gc (genomic copies)/100 mL). In both cases, the estimated disease risk associated with Campylobacter and recreational exposure was higher than the Dutch national incidence. This indicates that the health risk associated with recreational exposure to the water plaza is significant. L. pneumophila was found only in two out of ten pond samples. Legionnaire's disease risks were lower than the Dutch national incidence. Presence of human Bacteroides indicates possible cross-connections with the CSS that should be identified and removed.

    The goal of the present article is to compile a corpus of indicators of eHealth development evaluation that would essentially reflect stakeholder approaches and complement technical indicators of assessment of an eHealth system. Consequently, the assessment of the development of an eHealth system would reflect stakeholder approaches and become an innovative solution in attempting to improve productivity of IT projects in the field of health care. The compiled minimum set of indicators will be designed to monitor implementation of the national eHealth information system. To ensure reliability of the quality research, the respondents were grouped in accordance to the geographical distribution and diversity of the levels and types of the represented jobs and institutions. The applied analysis implies several managerial insights on the hierarchy of eHealth indicators. These insights may be helpful in recommending priority activities in implementation of an eHealth data system on the national or international level. The research is practically useful as it is the first to deal with the topic in Lithuania and its theoretical and practical aspect are particularly relevant in implementation of an eHealth data system in Lithuania. The eHealth assessment indicators presented in the article may be practically useful in two aspects: (1) as key implementation guidelines facilitating the general course of eHealth system development and (2) as a means to evaluate eHealth outcomes.

    © Springer International Publishing Switzerland 2015. Cold seeps are unique ecosystems that are generally characterized by high salinity and reducing solutions. Seepage fluid, the major water influx of this system, contains hypersaline water, sediment pore water, and other components. The Thuwal cold seeps were recently discovered on the continental margin of the Red Sea. Using 16S rRNA gene pyro-sequencing technology, microbial communities were investigated by comparing samples collected in 2011 and 2013. The results revealed differences in the microbial communities between the two sampling times. In particular, a significantly higher abundance of Marine Group I (MGI) Thaumarchaeota was coupled with lower salinity in 2013. In the brine pool, the dominance of Desulfobacterales in 2011 was supplanted byMGI Thaumarchaeota in 2013, perhaps due to a reduced supply of hydrogen sulfide from the seepage fluid. Collectively, this study revealed a difference in water components in this ecosystem between two sampling times. The results indicated that the seawater in this cold seep displayed a greater number of characteristics of normal seawater in 2013 than in 2011, which might represent the dominant driving force for changes in microbial community structures. This is the first study to provide a temporal comparison of the microbial biodiversity of a cold seep ecosystem in the Red Sea.

    Increasingly, scientists are being called upon to assist in the development of indicators for monitoring ecosystem health. For human health indicators, they may draw on environmental exposure, human morbidity/mortality or well-being and sustainability approaches. To improve the rigour of indicators, we propose six scientific criteria for indicator selection: (1) data availability, suitability and representativeness (of populations), (2) indicator validity (face, construct, predictive and convergent) and reliability; (3) indicator responsiveness to change; (4) indicator desegregation capability (across personal and community characteristics); (5) indicator comparability (across populations and jurisdictions); and (6) indicator representativeness (across important dimensions of concern). We comment on our current capacity to adhere to such criteria with examples of measures of environmental exposure, human health and sustainability. We recognize the considerable work still required on documenting environment-human health relationships and on monitoring potential indicators in similar ways over time. Yet we argue that such work is essential in order for science to inform policy decisions which affect the health of ecosystems and human health. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam.

  7. Recent advances in microbial fermentation for dairy and health

    2017-01-01

    Microbial fermentation has been used historically for the preservation of foods, the health benefits of which have since come to light. Early dairy fermentations depended on the spontaneous activity of the indigenous microbiota of the milk. Modern fermentations rely on defined starter cultures with desirable characteristics to ensure consistency and commercial viability. The selection of defined starters depends on specific phenotypes that benefit the product by guaranteeing shelf life and ensuring safety, texture, and flavour. Lactic acid bacteria can produce a number of bioactive metabolites during fermentation, such as bacteriocins, biogenic amines, exopolysaccharides, and proteolytically released peptides, among others. Prebiotics are added to food fermentations to improve the performance of probiotics. It has also been found that prebiotics fermented in the gut can have benefits that go beyond helping probiotic growth. Studies are now looking at how the fermentation of prebiotics such as fructo-oligosaccharides can help in the prevention of diseases such as osteoporosis, obesity, and colorectal cancer. The potential to prevent or even treat disease through the fermentation of food is a medically and commercially attractive goal and is showing increasing promise. However, the stringent regulation of probiotics is beginning to detrimentally affect the field and limit their application. PMID:28649371

  8. Air quality as respiratory health indicator: a critical review.

    Moshammer, Hanns; Wallner, Peter

    2011-09-01

    As part of the European Public Health project IMCA II validity and practicability of "air pollution" as a respiratory health indicator were analyzed. The definitions of air quality as an indicator proposed by the WHO project ECOEHIS and by IMCA I were compared. The public availability of the necessary data was checked through access to web-based data-bases. Practicability and interpretation of the indicator were discussed with project partners and external experts. Air quality serves as a kind of benchmark for the good health-related environmental policy. In this sense, it is a relevant health indicator. Although air quality is not directly in the responsibility of health policy, its vital importance for the population's health should not be neglected. In principle, data is available to calculate this IMCA indicator for any chosen area in Europe. The indicator is relevant and informative, but calculation and interpretation need input from local expert knowledge. The European health policy is well advised to take air quality into account. To that end, an interdisciplinary approach is warranted. The proposed definition of air quality as a (respiratory) health indicator is workable, but correct interpretation depends on expert and local knowledge.

    Groundwater quality is often evaluated using microbial indicators. This study examines data from 12 international groundwater studies (conducted 1992-2013) of 718 public drinking-water systems located in a range of hydrogeological settings. Focus was on testing the value of indicator organisms for identifying virus-contaminated wells. One or more indicators and viruses were present in 37 and 15% of 2,273 samples and 44 and 27% of 746 wells, respectively. Escherichia coli ( E. coli) and somatic coliphage are 7-9 times more likely to be associated with culturable virus-positive samples when the indicator is present versus when it is absent, while F-specific and somatic coliphages are 8-9 times more likely to be associated with culturable virus-positive wells. However, single indicators are only marginally associated with viruses detected by molecular methods, and all microbial indicators have low sensitivity and positive predictive values for virus occurrence, whether by culturable or molecular assays, i.e., indicators are often absent when viruses are present and the indicators have a high false-positive rate. Wells were divided into three susceptibility subsets based on presence of (1) total coliform bacteria or (2) multiple indicators, or (3) location of wells in karst, fractured bedrock, or gravel/cobble settings. Better associations of some indicators with viruses were observed for (1) and (3). Findings indicate the best indicators are E. coli or somatic coliphage, although both indicators may underestimate virus occurrence. Repeat sampling for indicators improves evaluation of the potential for viral contamination in a well.

    In this study, four different mesophilic and thermophilic full-scale anaerobic digesters treating food wastewater (FWW) were monitored for 1-2years in order to investigate: 1) microbial communities underpinning anaerobic digestion of FWW, 2) significant factors shaping microbial community structures, and 3) potential microbial indicators of process instability. Twenty-seven bacterial genera were identified as abundant bacteria underpinning the anaerobic digestion of FWW. Methanosaeta harundinacea, M. concilii, Methanoculleus bourgensis, M. thermophilus, and Methanobacterium beijingense were revealed as dominant methanogens. Bacterial community structures were clearly differentiated by digesters; archaeal community structures of each digester were dominated by one or two methanogen species. Temperature, ammonia, propionate, Na + , and acetate in the digester were significant factors shaping microbial community structures. The total microbial populations, microbial diversity, and specific bacteria genera showed potential as indicators of process instability in the anaerobic digestion of FWW.

    2003-09-01

    Within the EU Health Monitoring Programme (HMP), the ECHI project has proposed a comprehensive list of 'European Community Health Indicators'. In the design of the indicator set, a set of explicit criteria was applied. These included: i) be comprehensive and coherent, i.e. cover all domains of the public health field; ii) take account of earlier work, especially that by WHO-Europe, OECD and Eurostat; and iii) cover the priority areas that Member States and Community health policies currently pursue. Flexibility is an important characteristic of the present proposal. In ECHI, this has been emphasized by the definition of 'user-windows'. These are subsets from the overall indicator list, each of which should reflect a specific user's requirement or interest. The proposed indicators are, in most cases, defined as generic indicators, i.e. their actual operational definitions have not yet been attempted. This work has been, and is being carried out to a large part by other projects financed under the HMP, which cover specific areas of public health or areas of data collection. Apart from indicators covered by regularly available data, indicators (or issues) have been proposed for which data are currently difficult to collect but which from a policy point of view would be needed. All this points to the fact that establishing an indicator list which is actually used by Member States is a continuously developing process. This process is now continued by the first strand of the new EU Public Health Action Programme.

    To compare microbiological indicator and pathogen contamination among different types of fresh produce and environmental samples along the production chain, 636 samples of produce (rinsates from cantaloupe melons, jalapeño peppers, and tomatoes) and environmental samples (rinsates from hands of workers, soil, and water) were collected at four successive steps in the production process (from the field before harvest through the packing facility) on 11 farms in northern Mexico during 2011 and 2012. Samples were assayed for enteric pathogens (Escherichia coli O157:H7, other Shiga toxigenic E. coli, Salmonella, and Listeria monocytogenes) and microbial indicators (coliforms, other E. coli strains, and Enterococcus spp.). Salmonella was the only pathogen detected; it was found in one preharvest jalapeño sample (detection limits: 0.0033 CFU/ml in produce and hand samples, 0.0013 CFU/ml in water, and 0.04 CFU/g in soil). Microbial indicator profiles for produce, worker hands, and soil from jalapeño and tomato farms were similar, but cantaloupe farm samples had higher indicator levels (P soil (indicators were significantly more prevalent (70 to 89% of samples were positive; P = 0.01 to 0.02), and geometric mean levels were higher (0.3 to 0.6 log CFU/100 ml) than those in cantaloupe farm water (32 to 38% of samples were positive, geometric mean indicators were present during all production steps, but prevalence and levels were generally highest at the final on-farm production step (the packing facility) (P type and production step can inform the design of effective approaches to mitigate microbial contamination.

    2014-12-01

    In the Middle East, dust and sand storms are a persistent problem and can deliver significant amounts of micro-particulates via inhalation into the mouth, nasal pharynx, & lungs due to the fine size and abundance of these micro-particulates. The chronic and acute health risks of this dust inhalation have not been well studied nor has the dust been effectively characterized as to its chemical composition, mineral content, or microbial flora. Scientific experiments were designed to study the Kuwaiti and Iraqi dust as to its physical, chemical, and biological characteristics and for its potential to cause adverse health effects. First, dust samples from different locations were collected and processed and exposure data collected. Initial chemical and physical characterization of each sample including particle size distribution and inorganic analysis was conducted, followed by characterization of biologic flora of the dust, including bacteria, fungi and viruses. Data indicates that the mineralized dust is composed of calcium carbonate over a matrix of metallic silicate nanocrystals containing a variety of trace and heavy metals constituting ~3 % of the PM10 particles by weight, of which ~1% is bioaccessible aluminum and reactive iron, each. The particles also consist of ~1% bioavailable aluminum and reactive iron each. Microbial analysis reveals a significant biodiversity of bacterial, fungi, and viruses of which ~30% are known pathogens. Of the microbes identified, several have hemolytic properties and most have significant antibiotic resistance. Viral analysis indicates a tremendous amount of virons with a large percent of RNA viruses. The level of total suspended particle mass at PM 10 along with environmental & physiological conditions present constitute an excessive exposure to micro-particulates including PM 2.5 and the potential for adverse health effects. Reported data on cell culture and animal studies have indicated a high level of toxicity to these dust

    2007-06-01

    Full Text Available This study describes the relations between the European Union standardized health indicators and the community-based health policy. One of the goals of the European Commission is to provide standardized information on health in order to make it comparable at a trans-national level. Hence, numerous projects aimed at developing health indicators, and improving databases relating to these were supported by the Program of Community Action in the Field of Public Health. In this paper the authors argue that standardized health indicators can provide more than a prototype for a future health monitoring system. Bearing in mind that the production of comparable information on health is based upon four different tasks (the analysis of data needs in a specific area, definition of indicators and quality assurance, reporting and analysis, and promotion of the results the authors assert that all of these tasks are important steps towards the development of community-based health policy. Thus, the main objective of this study is to analyze their utility as premises for policy development.

    The relationship between microbial community structure and function has been examined in detail in natural and engineered environments, but little work has been done on using microbial community information to predict function. We processed microbial community and operational data from controlled experiments with bench-scale bioreactor systems to predict reactor process performance. Four membrane-operated sequencing batch reactors treating synthetic wastewater were operated in two experiments to test the effects of (i) the toxic compound 3-chloroaniline (3-CA) and (ii) bioaugmentation targeting 3-CA degradation, on the sludge microbial community in the reactors. In the first experiment, two reactors were treated with 3-CA and two reactors were operated as controls without 3-CA input. In the second experiment, all four reactors were additionally bioaugmented with a Pseudomonas putida strain carrying a plasmid with a portion of the pathway for 3-CA degradation. Molecular data were generated from terminal restriction fragment length polymorphism (T-RFLP) analysis targeting the 16S rRNA and amoA genes from the sludge community. The electropherograms resulting from these T-RFs were used to calculate diversity indices - community richness, dynamics and evenness - for the domain Bacteria as well as for ammonia-oxidizing bacteria in each reactor over time. These diversity indices were then used to train and test a support vector regression (SVR) model to predict reactor performance based on input microbial community indices and operational data. Considering the diversity indices over time and across replicate reactors as discrete values, it was found that, although bioaugmentation with a bacterial strain harboring a subset of genes involved in the degradation of 3-CA did not bring about 3-CA degradation, it significantly affected the community as measured through all three diversity indices in both the general bacterial community and the ammonia-oxidizer community (

    To develop public health adaptation strategies and to project the impacts of climate change on human health, indicators of vulnerability and preparedness along with accurate surveillance data on climate-sensitive health outcomes are needed. We researched and developed environmental health indicators for inputs into human health vulnerability assessments for climate change and to propose public health preventative actions. We conducted a review of the scientific literature to identify outcomes and actions that were related to climate change. Data sources included governmental and nongovernmental agencies and the published literature. Sources were identified and assessed for completeness, usability, and accuracy. Priority was then given to identifying longitudinal data sets that were applicable at the state and community level. We present a list of surveillance indicators for practitioners and policy makers that include climate-sensitive health outcomes and environmental and vulnerability indicators, as well as mitigation, adaptation, and policy indicators of climate change. A review of environmental health indicators for climate change shows that data exist for many of these measures, but more evaluation of their sensitivity and usefulness is needed. Further attention is necessary to increase data quality and availability and to develop new surveillance databases, especially for climate-sensitive morbidity.

    2017-12-01

    Sexual minorities experience higher rates of several physical health problems compared to their heterosexual counterparts. The present study uses Meyer's Minority Stress Model (Psychological Bulletin, 129(5): 674-697, 2003) to examine physical health indicators among 250 adults who identified as sexual minorities. Study hypotheses include that sexual minority stress is predictive of two physical health indicators (i.e., engagement in a health-promoting lifestyle and number of physical health problems) and that planning (i.e., problem-focused) and social support coping will partially mediate the relationship between sexual minority stress and each physical health indicator. Results showed that as level of sexual minority stress increased, engagement in a health-promoting lifestyle decreased and the number of physical health problems increased. Planning and social support coping did not mediate these relationships; however, as levels of coping increased, engagement in a health-promoting lifestyle increased. These findings have implications for researchers and healthcare professionals in their efforts to promote the physical health of sexual minorities.

    Background The strengthening of primary health care is one major goal of the current national health reform in Austria. In this context, a new interdisciplinary concept was developed in 2014 that defines structures and requirements for future primary health care facilities. Objective The aim of this project was the development of quality indicators for the evaluation of the scheduled primary health care facilities in Austria, which are in accordance with the new Austrian concept. Methods We used the RAND/NPCRDC method for the development and selection of the quality indicators. We conducted systematic literature searches for existing measures in international databases for quality indicators as well as in bibliographic databases. All retrieved measures were evaluated and rated by an expert panel in a 2-step process regarding relevance and feasibility. Results Overall, the literature searches yielded 281 potentially relevant quality indicators, which were summarized to 65 different quality measures for primary health care. Out of these, the panel rated and accepted 30 measures as relevant and feasible for use in Austria. Five of these indicators were structure measures, 14 were process measures and the remaining 11 were outcome measures. Based on the Austrian primary health care concept, the final set of quality indicators was grouped in the 5 following domains: Access to primary health care (5), quality of care (15), continuity of care (5), coordination of care (4), and safety (1). Conclusion This set of quality measures largely covers the four defined functions of primary health care. It enables standardized evaluation of primary health care facilities in Austria regarding the implementation of the Austrian primary health care concept as well as improvement in healthcare of the population. © Georg Thieme Verlag KG Stuttgart · New York.

    2003-07-01

    An environmental assessment conducted at Repulse Bay, Nunavut in the summer of 2001 revealed a recent diesel spill flowing from the groundwater into a creek. The spill had not been reported. When Arctic surface waters mix with hydrocarbon impacted groundwater and sediments, distinctive mats of diatom, cyanobacteria and other bacteria are formed. These mats have the potential for phytoremediation of hydrocarbons. This paper explained the apparent dominance of mats in contaminated Arctic waters and why they promote biodegradation of hydrocarbons. Hydrocarbon-contaminated soils and groundwater are generally anaerobic. The higher dissolved carbon dioxide in polluted soils and groundwater can benefit photosynthetic cyanobacteria and diatom found in oligotrophic, lower alkalinity Arctic waters. The anaerobic and aerobic bacteria can potentially take advantage of the hydrogen substrate and the nitrogen fixing abilities of the cyanobacteria. Zooplankton predators may be killed off by the toxicity of the polluted groundwater. The paper provides examples where a microbial mat reduced the sulfate content of a hydrocarbon-impacted Arctic stream by 100 ppm, and where a pond covered in a benthic microbial mat showed no evidence of hydrocarbons in the water overlying sediments contaminated with hydrocarbons at concentrations measured at 30,000 ppm. 19 refs., 3 tabs., 8 figs.

    Air environmental health indicators were defined operationally as a combination of air quality and air-related health indicators. Clean air is a basic precondition of human health. Air pollutants had been identified with potential negative impact on health especially on respiratory and cardiovascular diseases. Thus, studies are necessary to identify and understand the state of environmental health. This study was aimed to examine and analyses the air environmental health condition in city of Kuala Lumpur by using a set of indicators. House to house questionnaire survey was carried out to collect air-related health data, and air quality sampling was carried out to identify ambient air quality level of the city. In general, city of Kuala Lumpur was found to have a moderate level of air quality. Air-related illnesses indicated by acute respiratory infection and asthma were found to be higher in more developed or higher density zones, as compared to other zones. Besides, air-related illnesses were significantly correlated to respondents exposure to air pollution. The findings imply that human health can be improved by managing the urban development and its environmental quality properly. (author)

    Objectives: To identify indicators of accuracy for consumer health information on the Internet. The results will help lay people distinguish accurate from inaccurate health information on the Internet. Design: Several popular search engines (Yahoo, AltaVista, and Google) were used to find Web pages on the treatment of fever in children. The accuracy and completeness of these Web pages was determined by comparing their content with that of an instrument developed from authoritative sources on treating fever in children. The presence on these Web pages of a number of proposed indicators of accuracy, taken from published guidelines for evaluating the quality of health information on the Internet, was noted. Main Outcome Measures: Correlation between the accuracy of Web pages on treating fever in children and the presence of proposed indicators of accuracy on these pages. Likelihood ratios for the presence (and absence) of these proposed indicators. Results: One hundred Web pages were identified and characterized as “more accurate” or “less accurate.” Three indicators correlated with accuracy: displaying the HONcode logo, having an organization domain, and displaying a copyright. Many proposed indicators taken from published guidelines did not correlate with accuracy (e.g., the author being identified and the author having medical credentials) or inaccuracy (e.g., lack of currency and advertising). Conclusions: This method provides a systematic way of identifying indicators that are correlated with the accuracy (or inaccuracy) of health information on the Internet. Three such indicators have been identified in this study. Identifying such indicators and informing the providers and consumers of health information about them would be valuable for public health care. PMID:11751805

    The need to replace the commonly applied fecal indicator conversions ratio (an assumption of 1:10 -5 virus to fecal indicator organism) in Quantitative Microbial Risk Assessment (QMRA) with models based on quantitative data on the virus of interest has gained prominence due to the different physical and environmental factors that might influence the reliability of using indicator organisms in microbial risk assessment. The challenges facing analytical studies on virus enumeration (genome copies or particles) have contributed to the already existing lack of data in QMRA modelling. This study attempts to fit a QMRA model to genome copies of norovirus data. The model estimates the risk of norovirus infection from the intake of vegetables irrigated with wastewater from different sources. The results were compared to the results of a corresponding model using the fecal indicator conversion ratio to estimate the norovirus count. In all scenarios of using different water sources, the application of the fecal indicator conversion ratio underestimated the norovirus disease burden, measured by the Disability Adjusted Life Years (DALYs), when compared to results using the genome copies norovirus data. In some cases the difference was >2 orders of magnitude. All scenarios using genome copies met the 10 -4 DALY per person per year for consumption of vegetables irrigated with wastewater, although these results are considered to be highly conservative risk estimates. The fecal indicator conversion ratio model of stream-water and drain-water sources of wastewater achieved the 10 -6 DALY per person per year threshold, which tends to indicate an underestimation of health risk when compared to using genome copies for estimating the dose.

    Two years after the implementation of the Health Sector Evolution Plan (HSEP), this study evaluated the effects of the plan on health equity indices. The main indices assessed by the study were the Out-of-Pocket (OOP) health expenditures, the Fairness in Financial Contribution (FFC) to the health system index, the index of households' Catastrophic Health Expenditure (CHE) and the headcount ratio of Impoverishing Health Expenditure (IHE). The per capita share of costs for total health services has been decreased. The lowered costs have been more felt in rural areas, generally due to sharp decrease in inpatient costs. Per capita pay for outpatient services is almost constant or has slightly increased. The reform plan has managed to improve households' Catastrophic Health Expenditure (CHE) index from an average of 2.9% before the implementation of the plan to 2.3% after the plan. The Fairness in Financial Contribution (FFC) to the health system index has worsened from 0.79 to 0.76, and the headcount ratio of Impoverishing Health Expenditure (IHE) index deteriorated after the implementation of plan from 0.34 to 0.50. Considerable improvement, in decreasing the burden of catastrophic hospital costs in low income strata which is about 26% relative to the time before the implementation of the plan can be regarded as the main achievement of the plan, whereas the worsening in the headcount ratio of IHE and FFC are the equity bottlenecks of the plan.

    The Lahore canal is an important watershed in Lahore. The present study was conducted to monitor pollution load of Lahore canal. Surface water was collected from the middle of the canal at four different sites, and analysed for physicochemical parameters (temperature, pH, EC, DO, BOD/sub 5/, turbidity, nitrates, phosphates) and microbial load (bacteria (TVC), total coliform and fungi). Water quality parameters were monitored from May to August at four sites along 17Km long patch. Surface water was collected in the middle of the canal. The results were compared with IWQ guidelines proposed by WWF, Pakistan. Pollution load of Lahore Canal revealed an alarming situation. Water can be used for the irrigation purpose, but only with advanced treatment. (author)

    The article presents the basic principles of health care, health care measures and strategic objectives of these measures in Croatia. The health of the population does not depend solely on the activities of the health care system but also on various demographic indicators. Our success in implementing health care depends largely on the structure of health facilities and health workers. The Croatian health system in late 2013 had permanently employed 74,489 workers. Out of these, 77% were health care workers. Most health care workers had only secondary school education (37.7%); physicians represented 17.4% of the workforce. On assessing the health of the population, certain health indicators are of utmost importance. The leading cause of deaths were circulatory diseases (in 2012, 24,988 persons died, 585.5/100,000). Neoplasms were the cause of death in 13,940 persons (326.6/100,000), then injuries and poisoning (69.1/100,000), diseases of the gastrointestinal system (53.1/100,000), and respiratory diseases (50.4/100,000). Data are presented on the basis of diseases reported from several national registries (cancer, psychoactive drug abuse, the disabled, diabetes, and suicides). The importance of vaccination for the control of infectious diseases in Croatia is especially emphasized, as well as the experience and excellent results achieved in this area. The epidemiological situation in Croatia in terms of infectious diseases can be assessed as favorable. This is due to the general living conditions, which contributed to the entire health system, making Croatia equal to other developed countries of Europe and throughout the world.

    Assessing recreational water quality requires a fundamental understanding of metal-microbial interactions and the key biogeochemical processes occurring in urban public beaches. Metals play an important role in the distribution and virulence (e.g. resistance) of microorganisms in water systems. In turn, microorganisms have a significant influence on metal cycling, thus affecting metal mobility, bioavailability and toxicity in the aquatic environment. Bacteria adhere to floc, small suspended mineral-bacterial aggregates, in aquatic systems resulting in high-density floc-associated bacterial biofilm communities. These nanoparticulate bacterial microhabitats are important environmental sinks for metals and potential reservoirs for antibiotic resistant and pathogenic bacteria. The objectives of this study are to identify and quantify (1) metal distributions among suspended floc, bed sediment and water-column aqueous compartments (2) important biogeochemical processes influencing metal cycling and (3) linkages between floc metals and the occurrence of floc associated antibiotic resistant bacteria and pathogens across a series of variably contaminated aquatic systems. Results of this project will provide new diagnostic indicators of pathogens in recreational water systems and aid in the development of public health policies to improve water quality and reduce water borne infectious disease. Here, results will be presented assessing the metal and microbial community dynamics in samples collected from Toronto's Sunnyside Beach (May 13 and August 20), an urban public beach on Lake Ontario. Water column, floc and bed sediments near and offshore were analyzed for physico-chemical characteristics and metal concentrations. Floc were imaged using DAPI and FISH to assess microbial community structure. Results to date, characterizing the linkages amongst bacteria, metal contaminant concentrations and sediment partitioning and system physico-chemical conditions will be discussed.

    Despite its progress in terms of socio-economic indicators, Brazil is still unequal, which is due to an unequal and exclusionary historical process. In this paper we selected the Human Development Index - HDI and other social, economic, environmental and health indicators to exemplify this situation. We selected the municipalities that had the lowest HDI in the country in 2000 comparing their evolution over time between 2000 and 2010 by means of indicators linked to the economic, environmental and social pillars of sustainable development. These municipalities have an HDI classified as low (sustainable development with quality of life, the improvement of sanitation and education indicators should be a priority for Brazil.

    Ecological diversity indices are frequently applied to molecular profiling methods, such as terminal restriction fragment length polymorphism (T-RFLP), in order to compare diversity among microbial communities. We performed simulations to determine whether diversity indices calculated from T-RFLP profiles could reflect the true diversity of the underlying communities despite potential analytical artifacts. These include multiple taxa generating the same terminal restriction fragment (TRF) and rare TRFs being excluded by a relative abundance (fluorescence) threshold. True community diversity was simulated using the lognormal species abundance distribution. Simulated T-RFLP profiles were generated by assigning each species a TRF size based on an empirical or modeled TRF size distribution. With a typical threshold (1%), the only consistently useful relationship was between Smith and Wilson evenness applied to T-RFLP data (TRF-E(var)) and true Shannon diversity (H'), with correlations between 0.71 and 0.81. TRF-H' and true H' were well correlated in the simulations using the lowest number of species, but this correlation declined substantially in simulations using greater numbers of species, to the point where TRF-H' cannot be considered a useful statistic. The relationships between TRF diversity indices and true indices were sensitive to the relative abundance threshold, with greatly improved correlations observed using a 0.1% threshold, which was investigated for comparative purposes but is not possible to consistently achieve with current technology. In general, the use of diversity indices on T-RFLP data provides inaccurate estimates of true diversity in microbial communities (with the possible exception of TRF-E(var)). We suggest that, where significant differences in T-RFLP diversity indices were found in previous work, these should be reinterpreted as a reflection of differences in community composition rather than a true difference in community diversity.

    Managed Aquifer Recharge (MAR) is becoming an attractive option for water storage in water reuse processes as it provides an additional treatment barrier to improve recharged water quality and buffers seasonal variations of water supply and demand. To achieve a better understanding about the level of pathogenic microorganisms and their relation with microbial indicators in these systems, five waterborne pathogens and four microbial indicators were monitored over one year in three European MAR sites operated with reclaimed wastewater. Giardia and Cryptosporidium (oo)cysts were found in 63.2 and 36.7% of the samples respectively. Salmonella spp. and helminth eggs were more rarely detected (16.3% and 12.5% of the samples respectively) and Campylobacter cells were only found in 2% of samples. At the Belgian site advanced tertiary treatment technology prior to soil aquifer treatment (SAT) produced effluent of drinking water quality, with no presence of the analysed pathogens. At the Spanish and Italian sites amelioration of microbiological water quality was observed between the MAR injectant and the recovered water. In particular Giardia levels decreased from 0.24-6.14 cysts/L to 0-0.01 cysts/L and from 0.4-6.2 cysts/L to 0-0.07 cysts/L in the Spanish and Italian sites respectively. Salmonella gene copies and Giardia cysts were however found in the water for final use and/or the recovered groundwater water at the two sites. Significant positive Spearman correlations (p<0.05, r(s) range: 0.45-0.95) were obtained, in all the three sites, between Giardia cysts and the most resistant microbial markers, Clostridium spores and bacteriophages.

    Viral communities are important for ecosystem function as they are involved in critical biogeochemical cycles and controlling host abundance. This study investigates riverine viral communities around a small rural town that influences local water inputs. Myoviridae, Siphoviridae, Phycodnaviridae, Mimiviridae, Herpesviridae, and Podoviridae were the most abundant families. Viral species upstream and downstream of the town were similar, with Synechoccocus phage, salinus, Prochlorococcus phage, Mimivirus A, and Human herpes 6A virus most abundant, contributing to 4.9-38.2% of average abundance within the metagenomic profiles, with Synechococcus and Prochlorococcus present in metagenomes as the expected hosts for the phage. Overall, the majority of abundant viral species were or were most similar to those of marine origin. At over 60 km to the river mouth, the presence of marine communities provides some support for the Baas-Becking hypothesis "everything is everywhere, but, the environment selects." We conclude marine microbial species may occur more frequently in freshwater systems than previously assumed, and hence may play important roles in some freshwater ecosystems within tens to a hundred kilometers from the sea. © 2016 The Authors.

    Full Text Available South East Queensland is one of the fastest growing regions in Australia with a correspondingly rapid increase in sewage production. In response, local councils are investing in more effective and sustainable options for the treatment and reuse of domestic and industrial effluents. A novel, evaporative solar dryer system has been installed on the Sunshine Coast to convert sewage sludge into a drier, usable form of biosolids through solar radiation exposure resulting in decreased moisture concentration and pathogen reduction. Solar-dried biosolids were analyzed for selected pathogenic microbial, metal and organic contaminants at the end of different drying cycles in a collaborative study conducted with the Regional Council. Although fecal coliforms were found to be present, enteroviruses, parasites, E. coli, and Salmonella sp. were not detected in the final product. However, elevated levels of zinc and copper were still present which restricted public use of the biosolids. Dilution of the dried biosolids with green waste as well as composting of the biosolids is likely to lead to the production of an environmentally safe, Class A end-product.

    Eskom's Koeberg Nuclear Power Station has maintained and reported on the WANO Chemistry Performance Index for a number of years. Because of the masking effects of multiple averaging, the value of the Index was questionable. The modified WANO Chemistry Performance Indicator, introduced recently, was considered an improvement. However, it was felt that it is too general to adequately address the long-term plant health management needs of a specific plant; a more tailored, plant-specific indicator is needed. A system of indices for measuring and managing long-term plant health at Eskom's 10 large fossil-fired power stations had been developed in 1996. The major success of these indices in improving plant performance management lay in their inclusion in station performance contracts. The Fossil Chemistry Index was based on the original WANO Chemistry Performance Index and suffered from the same shortcomings. Consequently, a major revision of this index was initiated to address these deficiencies. The objectives set for the revised common indicator were that target and limit values from Eskom Chemistry Standards should be incorporated, that the masking effect of multiple averaging be minimised or eliminated, that weighting factors be introduced to reflect the relative importance of selected parameters, that conditioning chemical effectiveness be monitored, and that ranges of values be accommodated. In tandem with this revision, there was requirement to include Koeberg in the reporting of long term plant health indicators. Instead of developing completely separate chemistry indicators for fossil and nuclear plant. A commonality of approach to Long Term Plant Health indicators was sought. This has resulted in a single indicator determination, with parameter selection, limit values, and target values providing the required plant specificity. (J.P.N.)

    Interactions between bacteria and protists are essential to the ecosystem ecology of fens. Until now, however, there has been almost no information on how restoration procedures in carbonate fens affect the functioning of microbial food webs. Changes in vegetation patterns resulting from restoration may take years to be observed, whereas microbial processes display effects even after short-term exposure to changes in environmental conditions caused by restoration. Therefore, microbial processes and patterns can be used as sensitive indicators of changes in environmental conditions. The present study attempts to verify the hypothesis that the species richness and abundance of microbial loop components would differ substantially before and after restoration. The effect of restoration processes on the functioning of the food web was investigated for a 10 years in a carbonate-rich fen, before and after restoration. The restoration procedure (particularly the improvement in hydrological conditions) distinctly modified the taxonomic composition and functioning of microbial food webs. This is reflected in the increased abundance and diversity of testate amoeba, i.e. top predators, within the microbial food web and in the pronounced increase in the abundance of bacteria. This study suggests potential use of microbial loop components as bio-indicators and bio-monitoring tools for hydrological status of fens and concentrations of nutrients. Better understanding of what regulates microbial populations and activity in fens and unravelling of these fundamental mechanisms are particularly critical in order to more accurately predict how fens will respond to global change or anthropogenic disturbances.

    The objective of this study was to evaluate whether indicator microbes and physical-chemical parameters were correlated with pathogens within a tidally influenced estuary. Measurements included the analysis of physical-chemical parameters (pH, salinity, temperature, and turbidity), measurements of bacterial indicators (enterococci, fecal coliform, E. coli, and total coliform), viral indicators (somatic and MS2 coliphage), viral pathogens (enterovirus by culture), and protozoan pathogens (Cryptosporidium and Giardia). All pathogen results were negative with the exception of one sample which tested positive for culturable reovirus (8.5 MPN/100 L).. Notable physical-chemical parameters for this sample included low salinity (<1 ppt) and high water temperature (31 °C). Indicator bacteria and indicator virus levels for this sample were within average values typically measured within the study site and were low in comparison with levels observed in other freshwater environments. Overall results suggest that high levels of bacterial and viral indicators were associated with low salinity sites. PMID:19464704

    Full Text Available The effect of crop sequences on soil quality indicators and its relationship with sudden death syndrome (SDS, a complex of Fusarium species was evaluated by physical, chemical, biochemical and molecular techniques. Regarding physical aspects, soybean/maize and maize monoculture exhibited the highest stable aggregate level, with values 41% and 43% higher than in soybean monoculture, respectively, and 133% higher than in bean monoculture. Bulk density (BD was higher in soybean monoculture, being 4% higher than in bean monoculture. The chemical parameters organic matter, total N, P, K, Mg, Ca, and water holding capacity also indicated that soybean/maize and maize monoculture improved soil quality. Fungal and bacterial community fingerprints generated using Terminal Restriction Fragment Length Polymorphism analysis of intergenic transcribed spacer regions of rRNA genes and 16S rRNA genes, respectively, indicated a clear separation between the rotations. Fatty acid profiles evaluated by FAME showed that bean monoculture had higher biomass of Gram (+ bacteria and stress indicators than maize monoculture, while the soybean/maize system showed a significant increase in total microbial biomass (total FAMEs content in comparison with soybean and bean monoculture. The incidence of SDS (Fusarium crassistipitatum was markedly higher (15% under soybean monoculture than when soybean was grown in rotation with maize. In the present work, soil microbial properties were improved under soybean/maize relative to continuous soybean. The improvement of soil health was one of the main causes for the reduction of disease pressure and crop yield improvement due to the benefits that crop rotation produces for soil quality.

    This study compares complementary feeding World Health Organization (WHO) indicators with those built in accordance with Brazilian recommendations (Ten Steps to Healthy Feeding). A cross-sectional study was carried out during the National Immunization Campaign against Poliomyelitis in Guarapuava-Paraná, Brazil, in 2012. Feeding data from 1,355 children aged 6-23 months were obtained through the 24 h diet recall. Based on five indicators, the proportion of adequacy was evaluated: introduction of solid, semi-solid, or soft foods; minimum dietary diversity; meal frequency; acceptable diet; and consumption of iron-rich foods. Complementary feeding showed adequacy higher than 85% in most WHO indicators, while review by the Ten Steps assessment method showed a less favorable circumstance and a high intake of unhealthy foods. WHO indicators may not reflect the complementary feeding conditions of children in countries with low malnutrition rates and an increased prevalence of overweight/obesity. The use of indicators according to the Ten Steps can be useful to identify problems and redirect actions aimed at promoting complementary feeding. © 2016 John Wiley & Sons Australia, Ltd.

    Since the 1978 Italian reform, an integrated network of community mental health services has been introduced. With few exceptions, research on determinants of mental health service use at the district level has focused on inpatient activities and social deprivation indicators. The European Psychiatric Care Assessment Team (EPCAT) standardized methodology allows for an evidence-based comparison of mental health systems between geographical areas. To compare service provision and utilization between local catchment areas; to explore quantitative relationships between residential and community service use and socio-demographic indicators at the ecological level. The European Socio-demographic Schedule (ESDS) was used to describe area characteristics, and the European Service Mapping Schedule (ESMS) to measure service provision and utilization in 18 catchment areas in Piedmont. Substantial variation in service use emerged. Acute hospital bed occupancy rates were lower in areas with more intensive community continuing care service users and with a smaller percentage of the population living alone. The non-acute hospital bed occupancy rate was directly related to the percentage of the population living alone or in overcrowded conditions, and to the level of mobile continuing care service users. Community continuing care service use was highest in areas with a larger percentage of the population living alone. Multiple regression models explained between 48 and 55% of the variation in inpatient and community service use between areas. Relationships based on ecological characteristics do not necessarily apply to the individual. This level of assessment, however, is necessary in evaluating mental health policy and service systems, and in allocating resources. The distribution of mental health care resources should be weighted in terms of indicators of social deprivation shown to be important predictors of both inpatient and community service use, as these are likely to be

    Full Text Available The efficiency of treatment in a wastewater treatment plant of Hat Yai Municipality through stabilization ponds and constructed wetlands was monitored by using the bacterial indicators, total coliforms (TC, fecal coliforms (FC, Escherichia coli and fecal streptococci (FS, and photosynthetic microbes. The sequence of water flow in the wastewater treatment plant is as follows: primary or anaerobic pond (P, facultative pond (F, maturation pond (M, constructed wetlands (W1, W2 and W3, and an effluent storage pond (S for the treated wastewater. The wastewater treatment plant has an approximate area of 3,264,000 m2 (2,040 rai and its dry weather flow was running at only 40,000 m3/ day. There were 10 sampling times used for all the 7 ponds during July-October, 2006.Statistical analysis using a Two-Factorial Design model, indicated that pond types significantly affected temperature, dissolved oxygen (DO, and pH (p<0.05, whereas the time of sampling during the day had a significant effect (p<0.05 only on the temperature and light intensity available to the ponds. There were also significant different removal efficiencies of the different bacterial indicator groups tested (p<0.05. The overall performance of the wastewater treatment plant effectively removed TC, FC, E. coli, and FS as follows, 99.8%, 99.8%, 75.8% and 98.8%, respectively. The amounts of bacterial indicators, except for E. coli, showed a negative correlation with levels of light intensity and DO, whereas there was no correlation between the pH and the different indicator bacteria. There was a positive middle level correlation between pHand chlorophyll a.There were five different divisions of photosynthetic organisms detected throughout the plant as follows, Cyanophyta, Chlorophyta, Bacillariophyta, Euglenophyta, and Pyrrhophyta. The least diversity was found in the anaerobic pond (P as there were only 15 genera. Euglena, an indicator of dirty water, was detected only in this pond. The

    Climate change scenarios predict an increase of intense rainfall events in summer in Western Europe. Current urban drainage systems cannot cope with such intense precipitation events. Cities are constructing local stormwater storage facilities to prevent pluvial flooding. Combining storage with other functions, such as recreation, may lead to exposure to contaminants. This study assessed the microbial quality of rainwater collected in a water plaza in Rotterdam (The Netherlands) and the health risks associated with recreational exposure. The water plaza collects street run-off, diverges first flush to the sewer system and stores the rest of the run-off in the plaza as open water. A rain simulation experiment was conducted using drinking water from fire hydrants. The water flowed over the street pavement into the street gutters and into the square. Samples were collected from the first flush diverted water and from two different levels of the water plaza at different points in time. Campylobacter spp., Cryptosporidium, and Legionella pneumophila were the pathogens investigated, using quantitative PCR. Escherichia coli was quantified with culture methods to obtain information on faecal contamination. Microbial source tracking tools (human Bacteroides, avian Helicobacter and canine mitochondrial DNA, all analysed with quantitative PCR) were used to determine the origin (human, animal) of the intestinal pathogens. To estimate the health risks for children playing in the water plaza after a rain event, a quantitative microbial risk assessment model was built. The volume of water ingested was obtained from literature on similar locations (flooded streets). Published dose-response models were used to calculate the risk per event. Exposure frequency was estimated using weather data (precipitation events). E. coli concentrations were below the level for excellent bathing water in the EU Bathing Water Directive. Cryptosporidium was not found in any sample. Campylobacter spp

    Bed stability is an important stream habitat attribute because it affects geomorphology and biotic communities. Natural resource managers desire indices of bed stability that can be used under a wide range of geomorphic conditions, are biologically meaningful, and are easily incorporated into sampling protocols. To eliminate potential bias due to presence of instream wood and increase precision of stability values, we modified a stream bed instability index (ISI) to include measurements of bankfull depth (d bf ) and median particle diameter (D 50 ) only in riffles and increased the pebble count to decrease variability (i.e., increase precision) in D 50 . The new riffle-based instability index (RISI) was compared to two established indices: ISI and the riffle stability index (RSI). RISI and ISI were strongly associated with each other but neither was closely associated with RSI. RISI and ISI were closely associated with both a diatom- and two macrovertebrate-based stream health indices, but RSI was only weakly associated with the macroinvertebrate indices. Unexpectedly, precision of D 50 did not differ between RISI and ISI. Results suggest that RISI is a viable alternative to both ISI and RSI for evaluating bed stability in multiple stream types. With few data requirements and a simple protocol, RISI may also better conform to riffle-based sampling methods used by some water quality practitioners.

    2012-01-01

    In Stone Town, Zanzibar, sewage treatment is minimal, with a biological oxygen demand reduction to 60% and no removal of bacteria or nutrients. Here, Stone Town’s sewage pollution was studied by measuring Enterococci and NH 4 + concentrations in seawater and δ 15 N of benthic organisms; samples were collected along the Stone Town shoreline and from offshore coral reefs. Public perceptions of sewage pollution were investigated via interviews. Enterococci from the Stone Town shoreline exceeded USEPA guidelines for recreational use. Benthic organisms from two of the four reefs were relatively enriched (δ 15 N > 10‰), indicative of sewage derived N. δ 15 N values of organisms from Stone Town exceeded 16‰. A strong correlation was found between Enterococci and δ 15 N across sites, while step-wise regression indicated rainfall and tidal stage as important predictors for bacterial concentrations. These data provide an important impact assessment from which the efficacy of future policy and management change can be assessed.

    The effect of lead (Pb) treatment on the soil microbial activities (soil microbial biomass and soil basal respiration) and rice physiological indices were studied by greenhouse pot experiment. Pb was applied as lead acetate at six different levels in two different paddy soils, namely 0 (control), 100, 300, 500, 700, 900 mg kg-1 soil. The results showed that the application of Pb at lower level (500 mg Pb kg-1 soil), which might be the critical concentration of Pb causing a significant decline in the soil microbial activities. However, the degree of influence on soil microbial activities by Pb was related to the clay and organic matter contents of the soils. On the other hand, when the level of Pb treatments increased to 500 mg kg-1, there was ecological risk for both soil microbial activities and plants. The results also revealed that there was a consistent trend that the chlorophyll contents increased initially, and then decreased gradually with increase in Pb concentration. Pb was effective in inducing proline accumulation and its toxicity causes oxidative stress in rice plants. In a word, soil microbial activities and rice physiological indices, therefore, may be sensitive indicators reflecting environmental stress in soil-Pb-rice system.

    General consumption of “western diet” characterized by high refined carbohydrates, fat and energy intake has resulted in a global obesity epidemics and related metabolic disturbance even for pregnant women. Pregnancy process is accompanied by substantial hormonal, metabolic and immunological changes during which gut microbiota is also remarkably remodeled. Dietary fiber has been demonstrated to have a striking role in shifting the microbial composition so as to improve host metabolism and health in non-pregnant individuals. The present study was conducted to investigate effects of adding a soluble dietary fiber inulin (0 or 1.5%) to low- or high- fat (0 or 5% fat addition) gestational diet on maternal and neonatal health and fecal microbial composition in a sow model. Results showed that inulin addition decreased the gestational body weight gain and fat accumulation induced by fat addition. Circulating concentrations of pro-inflammatory cytokine IL-6, adipokine leptin and chemerin were decreased by inulin supplementation. Inulin addition remarkably reduced the average BMI of newborn piglets and the within litter BMI distributions (%) ranging between 17 and 20 kg/m2, and increased the BMI distribution ranging between 14 and 17 kg/m2. 16S rRNA gene sequencing of the V3-V4 region showed that fecal microbial changes at different taxonomic levels triggered by inulin addition predisposed the pregnant sow to be thinner and lower inflammatory. Meanwhile, fecal microbial composition was also profoundly altered by gestation stage with distinct changes occurring at perinatal period. Most representative volatile fatty acid (VFA) producing-related genera changed dramatically when reaching the perinatal period and varied degrees of increases were detected with inulin addition. Fecal VFA concentrations failed to show any significant effect with dietary intervention, however, were markedly increased at perinatal period. Our findings indicate that positive microbial changes

    The present study evaluated the effects of dietary microbial phytase on the growth and gut health of hybrid tilapia (Oreochromis niloticus ♀×Oreochromis aureus ♂), focusing on the effect on intestinal histology, adhesive microbiota and expression of immune-related cytokine genes. Tilapia were fed either control diet or diet supplemented with microbial phytase (1000 U/kg). Each diet was randomly assigned to four groups of fish reared in cages (3×3×2 m). After 12 weeks of feeding, weight gain and feed conversion ratio of tilapia were not significantly improved by dietary microbial phytase supplementation. However, significantly higher level of P content in the scales, tighter and more regular intestinal mucosa folds were observed in the microbial phytase group and the microvilli density was significantly increased. The adhesive gut bacterial communities were strikingly altered by microbial phytase supplementation (0·41phytase, as indicated by the up-regulated intestinal expressions of the cytokine genes (tnf-α and tgf-β) and hsp70. In addition, the gut microvilli height was significantly decreased in the phytase group. These results indicate that dietary microbial phytase may exert mixed effects on hybrid tilapia, and can guide our future selection of phytases as aquafeed additives - that is, eliminating those that can stimulate intestinal inflammation.

    Fiałkiewicz-Kozieł, B; Smieja-Król, B; Ostrovnaya, T M; Frontasyeva, M; Siemińska, A; Lamentowicz, M

    We investigated a peat profile from the Izery Mountains, located within the so-called Black Triangle, the border area of Poland, Czech Republic, and Germany. This peatland suffered from an extreme atmospheric pollution during the last 50 years, which created an exceptional natural experiment to examine the impact of pollution on peatland microbes. Testate amoebae (TA), Centropyxis aerophila and Phryganella acropodia , were distinguished as a proxy of atmospheric pollution caused by extensive brown coal combustion. We recorded a decline of mixotrophic TA and development of agglutinated taxa as a response for the extreme concentration of Al (30 g kg -1 ) and Cu (96 mg kg -1 ) as well as the extreme amount of fly ash particles determined by scanning electron microscopy (SEM) analysis, which were used by TA for shell construction. Titanium (5.9 %), aluminum (4.7 %), and chromium (4.2 %) significantly explained the highest percentage of the variance in TA data. Elements such as Al, Ti, Cr, Ni, and Cu were highly correlated ( r  > 0.7, p  < 0.01) with pseudostome position/body size ratio and pseudostome position. Changes in the community structure, functional diversity, and mechanisms of shell construction were recognized as the indicators of dust pollution. We strengthen the importance of the TA as the bioindicators of the recent atmospheric pollution.

    This paper suggests new empirical DEA models for the measurement of health indicators and the allocation of health resources. The proposed models were developed by first suggesting a population-based health indicator. By introducing the suggested indicator into DEA models, a new approach that solves the problem of health resource allocation has been developed. The proposed models are applied to an empirical study of Taiwan's health system. Empirical findings show that the suggested indicator can successfully accommodate the differences in health resource demands between populations, providing more reliable performance information than traditional indicators such as physician density. Using our models and a commonly used allocation mechanism, capitation, to allocate medical expenditures, it is found that the proposed model always obtains higher performance than those derived from capitation, and the superiority increases as allocated expenditures rise.

    Several surveys of microbial indicators and pathogens were conducted to determine the impact of confined animal farming operations (CAFOs) on shallow, local, and regional groundwater quality in the Central Valley aquifer system, California. The aquifer system consists of highly heterogeneous, alluvial, unconsolidated coarse- to fine-grained sediments and is among the largest aquifers in the U.S.. Overlying landuse includes 3 million ha of irrigated agriculture and 1.7 million mature dairy cows in nearly 1,500 CAFOs. A multi-scale survey of water-borne indicator pathogens (Enterococcus spp. and generic E. coli) and of three water-borne pathogens (Campylobacter, Salmonella, and E. coli O157:H7) was conducted at five different spatial scales, increasing with distance from animal sources of these enteric microbial organisms: moist surfaces within individual CAFO sub-systems (calf-hutches, heifer corrals, mature cow stalls, hospital barn etc.), first encountered (shallow) groundwater immediately below these sub-systems, production aquifer below CAFOs, production aquifer near CAFOs, and production aquifer away from CAFOs. Where found, indicator pathogens were tested for antibiotic resistance. Hundreds of samples were collected at each scale: continuously during irrigation events and seasonally over a multi-year period at the three smaller site-scales; and in a one-time survey at the two larger, regional scales. All three pathogens were frequently detected in moist surface samples across CAFO sub-systems, albeit at concentrations several orders of magnitude lower than enteric indicators. Two of the three pathogens (but not Campylobacter) were also detected in first encountered groundwater, at 3-9 m below ground surface, in 1% of samples. No pathogens were found at the production aquifer scales. Generic E. coli was detected in ¼ of first encountered groundwater samples, and in 4% of production aquifer samples, while Enterococcus spp. was ubiquitously present across the

    Full Text Available Dietary preferences and nutrients composition have been shown to influence human and gut microbial metabolism, which ultimately has specific effects on health and diseases’ risk. Increasingly, results from molecular biology and microbiology demonstrate the key role of the gut microbiota metabolic interface to the overall mammalian host’s health status. There is therefore raising interest in nutrition research to characterize the molecular foundations of the gut microbial mammalian cross-talk at both physiological and biochemical pathway levels. Tackling these challenges can be achieved through systems biology approaches, such as metabolomics, to underpin the highly complex metabolic exchanges between diverse biological compartments, including organs, systemic biofluids and microbial symbionts. By the development of specific biomarkers for prediction of health and disease, metabolomics is increasingly used in clinical applications as regard to disease aetiology, diagnostic stratification and potentially mechanism of action of therapeutical and nutraceutical solutions. Surprisingly, an increasing number of metabolomics investigations in pre-clinical and clinical studies based on proton nuclear magnetic resonance (1H NMR spectroscopy and mass spectrometry (MS provided compelling evidence that system wide and organ-specific biochemical processes are under the influence of gut microbial metabolism. This review aims at describing recent applications of metabolomics in clinical fields where main objective is to discern the biochemical mechanisms under the influence of the gut microbiota, with insight into gastrointestinal health and diseases diagnostics and improvement of homeostasis metabolic regulation.

    Recent research has emphasized the importance of using physical, chemical, and biological indicators of stream health for diagnosing impaired watersheds and their receiving water bodies. A multidisciplinary team at the University of Minnesota is carrying out research to develop a stream classification system for Total Maximum Daily Load (TMDL) assessment. Funding for this research is provided by the United States Environmental Protection Agency and the Minnesota Pollution Control Agency. One objective of the research study involves investigating the relationships between indicators of stream health and localized stream characteristics. Measured data from Minnesota streams collected by various government and non-government agencies and research institutions have been obtained for the research study. Innovative Geographic Information Systems tools developed by the Environmental Science Research Institute and the University of Texas are being utilized to combine and organize the data. Simple linear relationships between index of biological integrity (IBI) and channel slope, two-year stream flow, and drainage area are presented for the Redwood River and the Snake River Basins. Results suggest that more rigorous techniques are needed to successfully capture trends in IBI scores. Additional analyses will be done using multiple regression, principal component analysis, and clustering techniques. Uncovering key independent variables and understanding how they fit together to influence stream health are critical in the development of a stream classification for TMDL assessment.

    Psychological stress is a major cause of lost working days in the UK. The Health & Safety Executive (HSE) has developed management standards (MS) to help organizations to assess work-related stress. To investigate the relationships between the MS indicator tool and employee health, job attitudes, work performance and environmental outcomes. The first phase involved a survey employing the MS indicator tool, General Health Questionnaire-12 (GHQ-12), job attitudes, work performance and environmental measures in a call centre from a large utility company. The second phase comprised six focus groups to investigate what employees believed contributed to their perceived stress. Three hundred and four call centre employees responded with a response rate of 85%. Significant negative correlations were found between GHQ-12 and two MS dimensions; demands (Rho = -0.211, P job performance, job motivation and increased intention to quit but low stress levels were associated with reduced job satisfaction. Lack of management support, recognition and development opportunities were identified as sources of stress. The findings support the utility of the MS as a measure of employee attitudes and performance.

    Female doctors in Hungary have worse indicators of physical and mental health compared with other professional women. We aimed to cast light on possible indicators of mental health, workload, and burnout of female physicians. Two time-points (T) were compared, in 2003 (T1 n = 408) and 2013 (T2 n = 2414), based on two nationally representative surveys of female doctors, and comparison made with data from other professional control groups. Independent samples t test or chi-squared test was used both for the two time-point comparison and the comparison between the index and the control groups. The background factors of sleep disorders and burnout were assessed by binary logistic regression analysis. No significant differences in the rates of depressive symptoms and suicidal thoughts and attempts were detected between the 2003 and 2013 cohorts, but the prevalence of sleep disorders increased. The workload increased, and there was less job satisfaction in 2013 than in 2003, coupled to more stressful or difficult work-related situations. The personal accomplishment component of burnout significantly decreased in line with the declining work-related satisfaction. Compared to the professional control groups, the prevalence of depressive symptoms, suicide attempts, and sleep disorders was higher among female physicians at both time-points. The number of workplaces, frequency of work-related stressful situations, and intensive role conflict was associated with sleep disorders and decreased personal accomplishment. In comparison with the other professional groups, female doctors had worse mental health indicators with regard to depression, suicidal ideas, and sleep disorders both in 2003 and 2013 while within professional strata the changes seemed to be less. Increasing workload had a clear impact on sleep disorders and the personal accomplishment dimension of burnout.

    Full Text Available BACKGROUND: To convert deserts into arable, green landscapes is a global vision, and desert farming is a strong growing area of agriculture world-wide. However, its effect on diversity of soil microbial communities, which are responsible for important ecosystem services like plant health, is still not known. METHODOLOGY/PRINCIPAL FINDINGS: We studied the impact of long-term agriculture on desert soil in one of the most prominent examples for organic desert farming in Sekem (Egypt. Using a polyphasic methodological approach to analyse microbial communities in soil as well as associated with cultivated plants, drastic effects caused by 30 years of agriculture were detected. Analysing bacterial fingerprints, we found statistically significant differences between agricultural and native desert soil of about 60%. A pyrosequencing-based analysis of the 16S rRNA gene regions showed higher diversity in agricultural than in desert soil (Shannon diversity indices: 11.21/7.90, and displayed structural differences. The proportion of Firmicutes in field soil was significantly higher (37% than in the desert (11%. Bacillus and Paenibacillus play the key role: they represented 96% of the antagonists towards phytopathogens, and identical 16S rRNA sequences in the amplicon library and for isolates were detected. The proportion of antagonistic strains was doubled in field in comparison to desert soil (21.6%/12.4%; disease-suppressive bacteria were especially enriched in plant roots. On the opposite, several extremophilic bacterial groups, e.g., Acidimicrobium, Rubellimicrobium and Deinococcus-Thermus, disappeared from soil after agricultural use. The N-fixing Herbaspirillum group only occurred in desert soil. Soil bacterial communities were strongly driven by the a-biotic factors water supply and pH. CONCLUSIONS/SIGNIFICANCE: After long-term farming, a drastic shift in the bacterial communities in desert soil was observed. Bacterial communities in agricultural

    Background 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. Objective 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. Design 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. Results 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.

    The aim of our study is to compare incidence of orthodontic malocclusion based on occlusal indices and Index of Orthodontic Treatment Need (IOTN), and to evaluate the most commonly used method among the dentists for orthodontic treatment in Sarajevo. The sample consisted of 110 (31 female and 79 male)subjects older than 16 years with complete permanent dentition. Subjects were examined according to Occlusal Index (Angle classification of malocclusion, overjet, overbite, dental arch crowding and tooth rotation) and IOTN index. We conduct survey regarding which indexes are used in deciding on orthodontic treatment need, among primary health care and Orthodontist. The present study show differences between the presence of malocclusion and treatment need as assessed by these two used indices. Based on the survey that we conduct all primary health care doctors use Occlusal Index to decide need for orthodontic treatment, more than 95% of orthodontic specialist use Occlusal Index for treatment need estimation. When measuring and grading treatment needs we should rely on Index of orthodontic treatment need. In such high demand for orthodontic treatment need it is necessary to establish need for the orthodontic treatment as fundamental, so that individuals with greatest treatment need can be assigned priority.

    To improve the quality of care in a Mental Health Hospital and identify the level of patient satisfaction. A descriptive, longitudinal, and retrospective study was conducted on 666 patients who completed treatment in the Mental Health Day Hospital of Salamanca, during the period 1994-2012, using the Hospital Management Annual Reports. A questionnaire designed for this purpose was used as the measurement tool. Most of the patients satisfactorily valued aspects, such as the general impression of the treatment (90% said «good/fairly good») and perception of being helped (94% perceived «very/fairly helped»); with 83% believing that the hospital is accessible. As regards empathy-understanding, it was noted that 14% feel discontent. While 18% of patients expected to be completely cured, the 83% of patients that finished their treatment have said that, in their opinion, the symptoms have subsided «very or somewhat». As regards the knowledge that they have about their disease, 30% believe it has advanced «a lot.» Based on the perceptions reported by patients, it may be said that in general, the level of user satisfaction in the Mental Health Day Hospital is high. Assessing quality through the user opinions helps control the quality, considering that patient satisfaction is a good indicator of result of the care received during their hospitalisation.

    New York, like many other states, provides county-level health statistics for use in local priority settings but does not provide any data on public views about priority health issues. This study assessed whether health department priorities are notably different from community concerns about health, and how both groups' priorities compare with local health statistics. Data from a 2009 rural survey on community health concerns were compared to priorities named by the seven area county health departments, and to local health indicator data. Health care/insurance cost (60%), obesity (53%), and prescription cost (41%) were leading community concerns, regardless of age, education, sex, or Internet in the home. Six of seven county health departments selected access to quality health care (which includes health care/insurance cost) as a leading public health priority, but only three identified obesity. The following leading local health issues were suggested by health indicators: Physical activity and nutrition, Smoking, and Unintentional injury. Health departments diverged from community priorities, from health indicator data, and from one another in choosing priorities. Adding a question about community health priorities to existing state telephone surveys on health behavior and lifestyle would provide an important tool to local health departments. © 2014 Society for Public Health Education.

    To assess the impact of health promotion programs and microcredit programs on three communities in the Dominican Republic. One community had only the health promotion program, one community had only the microcredit program, and one community had both a health promotion program and a microcredit program. This pilot project examined the hypothesis that the largest changes in 11 health indicators that were studied would be in the community with both a health promotion program and a microcredit program, that there would be intermediate changes in the community with only a health promotion program, and that the smallest changes would be in the community with only a microcredit program. The health promotion programs used community volunteers to address two major concerns: (1) the prevalent causes of mortality among children under 5 years of age and (2) women's health (specifically breast and cervical cancer screening). The microcredit program made small loans to individuals to start or expand small businesses. Outcome measures were based on comparisons for 11 health indicators from baseline community surveys (27 households surveyed in each of the three communities, done in December 2000 and January 2001) and from follow-up surveys (also 27 households surveyed in each of the three communities, in June and July 2002, after the health promotion program had been operating for about 13 months). Households were randomly chosen during both the baseline and follow-up surveys, without regard to their involvement in the microcredit or health promotion programs. The health indicators improved in all three communities. However, the degree of change was different among the communities (P microcredit and health promotion programs had the largest changes for 10 of the 11 health indicators. Multisector development is known to be important on a macroeconomic scale. The results of this pilot project support the view that multisector development is also important on a microeconomic level

    Full text: During the last 10 years there has been a remarkable growth of the attention for problems related to the electromagnetic pollution, motivated by the alert connected to potential risk for the health of persons and due to the increasing diffusion of Bats for mobile telecommunication as EMF sources. Many projects are being realized about the environmental and health impact of electromagnetic field and an important social role is played by specific actions to minimize the risk perception of the population. This study aims to find an innovative approach to these problems through the use of a system of continuous time monitoring of the electromagnetic fields and the individuation of appropriate environmental indicators. The proposed system monitors the electromagnetic fields continuously over time, and is already operating in many southern Italian cities. It works in a very efficient way as a mean for: a) Info to the citizens, thanks to diffusion of daily collected data on Internet Web; b) Control for local administrations and Authorities, due to capability of the system itself to alert when measured values exceed the limits reported by the Italian laws; c) Planning, for the implementation of : 1) New procedures agreed among local environmental control agency, local administrations and mobile Companies for network planning and management of alarm situations; 2) New local guidelines documents concerning the installation and operation of telecommunications apparatus. Moreover, starting from the general principles of the Strategic Environmental Evaluation (VAS), the environmental impacts of EMS field is studied. Based on the model DPSIR (Drivers, Pressure, State, Impacts, Responses), 12 environmental indicators have been chosen providing an immediate and understandable tool to obtain very important information on electromagnetic pollution generated by radio-telecommunication systems. The selected environmental indicators have been applied to 11 cities of the

  2. Health sector employment: a tracer indicator for universal health coverage in national Social Protection Floors.

    Health sector employment is a prerequisite for availability, accessibility, acceptability and quality (AAAQ) of health services. Thus, in this article health worker shortages are used as a tracer indicator estimating the proportion of the population lacking access to such services: The SAD (ILO Staff Access Deficit Indicator) estimates gaps towards UHC in the context of Social Protection Floors (SPFs). Further, it highlights the impact of investments in health sector employment equity and sustainable development. The SAD is used to estimate the share of the population lacking access to health services due to gaps in the number of skilled health workers. It is based on the difference of the density of the skilled health workforce per population in a given country and a threshold indicating UHC staffing requirements. It identifies deficits, differences and developments in access at global, regional and national levels and between rural and urban areas. In 2014, the global UHC deficit in numbers of health workers is estimated at 10.3 million, with most important gaps in Asia (7.1 million) and Africa (2.8 million). Globally, 97 countries are understaffed with significantly higher gaps in rural than in urban areas. Most affected are low-income countries, where 84 per cent of the population remains excluded from access due to the lack of skilled health workers. A positive correlation of health worker employment and population health outcomes could be identified. Legislation is found to be a prerequisite for closing access as gaps. Health worker shortages hamper the achievement of UHC and aggravate weaknesses of health systems. They have major impacts on socio-economic development, particularly in the world's poorest countries where they act as drivers of health inequities. Closing the gaps by establishing inclusive multi-sectoral policy approaches based on the right to health would significantly increase equity, reduce poverty due to ill health and ultimately contribute

    Public health practitioners are often called upon to make inference about a health indicator for a population at large when the sole available information are data gathered from a convenience sample, such as data gathered on visitors to a clinic. These data may be of the highest quality and quite extensive, but the biases inherent in a convenience sample preclude the legitimate use of powerful inferential tools that are usually associated with a random sample. In general, we know nothing about those who do not visit the clinic beyond the fact that they do not visit the clinic. An alternative is to take a random sample of the population. However, we show that this solution would be wasteful if it excluded the use of available information. Hence, we present a simple annealing methodology that combines a relatively small, and presumably far less expensive, random sample with the convenience sample. This allows us to not only take advantage of powerful inferential tools, but also provides more accurate information than that available from just using data from the random sample alone.

    Full Text Available The aim of the research was to determine the status of the secondary school students regarding different indicators of mental health. We were interested in the perception of successfulness, stress caused by the school, relationships towards friends and family members, intensive physical response to the stress, depression symptoms, eating disorders symptoms and substance abuse. The participants also estimated feeling of content and meaning in life. The questionnaire was designed especially for this research. 647 grammmar school and economics secondary school students were asked to participate in the study. The results are mostly similar to those of other Slovene surveys. There are major differences in problem areas depending on the sex of participants: girls' results show more physical responses to the stress, fear and the strain of learning, depression symptoms and eating disorders symptoms, while the boys reported more substance abuse, lower grades and less studying. The research shows the frequency of different problems in adolescents and correlations among forms of risk taking behavior. There are high correlations among different sorts of subsubstance abuse. Also depression, physical response to the stress and eating disorders symptoms are connected. The research should lead to various preventive programmes, where the efforts of the schools, health-care system, local community and the state have to be co-ordinated.

    The fact that the bacteria in the human gastrointestinal (GI) tract play a symbiotic role was noted as early as 1885, well before we began to manage microbial infections using antibiotics. However, even with the first antimicrobial compounds used in humans, the sulfa drugs, microbes were recognized to be critically involved in the biotransformation of these therapeutics. Thus, the roles played by the microbiota in physiology and in the management of human health have long been appreciated. De...

  12. Antibiotic, Pesticide, and Microbial Contaminants of Honey: Human Health Hazards

    Directory of Open Access Journals (Sweden)

    Noori Al-Waili

    2012-01-01

    Full Text Available Agricultural contamination with pesticides and antibiotics is a challenging problem that needs to be fully addressed. Bee products, such as honey, are widely consumed as food and medicine and their contamination may carry serious health hazards. Honey and other bee products are polluted by pesticides, heavy metals, bacteria and radioactive materials. Pesticide residues cause genetic mutations and cellular degradation and presence of antibiotics might increase resistant human or animal's pathogens. Many cases of infant botulisms have been attributed to contaminated honey. Honey may be very toxic when produced from certain plants. Ingestion of honey without knowing its source and safety might be problematic. Honey should be labeled to explore its origin, composition, and clear statement that it is free from contaminants. Honey that is not subjected for analysis and sterilization should not be used in infants, and should not be applied to wounds or used for medicinal purposes. This article reviews the extent and health impact of honey contamination and stresses on the introduction of a strict monitoring system and validation of acceptable minimal concentrations of pollutants or identifying maximum residue limits for bee products, in particular, honey.

    Authors: Patrick Cajandig*, Jose Ayala**, Nathaniel Cooper**, Catherine Courtier**, Hannah Nolan**, Rachelle Tallman**, T.E. Angela L. Quiros** * Davis High-School CA, **University of California Santa Cruz, Ecology and Evolutionary Biology Department Seagrasses are a key component in coastal ecosystems. Found in shallow marine environments, they make a large contribution to coastal ecosystem health by sustaining water quality, stabilizing the sea bottom, and providing habitat as well as food for other organisms. Seagrasses accumulate tiny grains of sediment, increasing water clarity. Just like barren hills are prone to erosion compared to vegetated, rooted down hills, we find a similar situation in the ocean. Seagrasses have broad roots that extend vertically and horizontally to help stabilize the seabed. Seagrasses support a whole ecosystem, because some organisms feed off of the seagrass alone, while others feed off the inhabitants of the seagrass. The quality of sediment is a vital part of seagrass health, just like nutrient rich soils are important to land plants. But what in seagrass sediment is a good indication of health? We hypothesize that seagrass health measures such as percent cover and seagrass species diversity are related to the abundance of foraminiferans relative to other seagrass sediment components. My mentor, T. E. Angela L. Quiros, from the University of California, Santa Cruz (UCSC), collected the sediment samples from seagrass beds in the Philippines. Samples were dried and brought to UCSC for sediment sieving. We used different sized sieves to sort the sediment. These sieves ranged from coarse to very fine sieves (Phi -2.0 (coarse) through +3.0 (fine) going in 0.5 intervals on a log scale). We weighed the sediment that was caught in each tray and separated them into bags of different size classes. To analyze each sample, we subsampled four size classes (Phi's -2.0, -1.5,-1.0, 0.0), and used a dissecting scope to identify and then weigh the

    Advances in lesbian, gay, and bisexual (sexual minority [SM]) acceptance and equality have been made in the past decade. However, certain SM subgroups continue to be disadvantaged due to lack of data and, thus, lack of knowledge about these populations. Data for older sexual minorities are especially lacking and will be increasingly important as more sexual minorities enter older age. This research explores results from a nationally representative health survey to elucidate some health indicators for older sexual minorities. Data from the 2013 and 2014 National Health Interview Surveys (NHIS) were pooled for increased sample size, and established research methods were followed as recommended by prior NHIS sexual orientation studies. We conducted descriptive analyses on the differences between SM and heterosexual groups, aged 65 years and older, for 12 health indicators. Four out of the 12 health indicators were significantly different for sexual minorities, and three out of those four indicated positive health outcomes or behaviors when compared with heterosexuals. Sexual minorities were more than three times as likely to receive HIV testing as heterosexual peers. Sexual minorities were more likely to receive an influenza vaccination, and much more likely to report excellent or very good health, than their heterosexual peers. Sexual minorities were more than twice as likely to report binge drinking, which is consistent with prior research for adult sexual minorities. This analysis is the first to examine national data on health indicators for sexual minorities, aged 65 years and older, using NHIS data. As more surveys begin to collect SMdata and more years of data are collected by NHIS, a clearer picture of the health of older adult sexual minorities should emerge.

    To identify the incidence of mortality, diarrheal diseases, scabies and falls; and the prevalence of pressure ulcers - all of which are related to the safety ofinstitutionalized older adults. This was a documentary retrospective study developed in a long-term residential careinstitution for older adults in the Northeast region of Brazil. The data were gathered from records of health assessment indicators filed between January 2008 and December 2015. Analysis included absolute case frequency; the sum of monthly prevalence and incidence rates; mean values of cases; and mean annual incidence and prevalence rates. The incidence of mortality over these nine years ranged from 9% to 13%; of acute diarrheic disease from 13% to 45%; and scabies from 21% to 63%. The prevalence of pressure ulcers ranged from 8% to 23%. Between 2012 and 2015, the incidence rate of falls without injury varied from 38% to 83%, and with injury from12% to 20%. Analysis of the health indicators revealeda high incidence of scabies and falls and a high prevalence of pressure ulcers. The identification of less than optimal rates for performance indicators canhelp improve the quality of nursing care.

    Longitudinal monitoring of patients suggests a causal link between chronic periodontitis and the development of Alzheimer’s disease (AD). However, the explanation of how periodontitis can lead to dementia remains unclear. A working hypothesis links extrinsic inflammation as a secondary cause of AD. This hypothesis suggests a compromised oral hygiene leads to a dysbiotic oral microbiome whereby Porphyromonas gingivalis, a keystone periodontal pathogen, with its companion species, orchestrates immune subversion in the host. Brushing and chewing on teeth supported by already injured soft tissues leads to bacteremias. As a result, a persistent systemic inflammatory response develops to periodontal pathogens. The pathogens, and the host’s inflammatory response, subsequently lead to the initiation and progression of multiple metabolic and inflammatory co-morbidities, including AD. Insufficient levels of essential micronutrients can lead to microbial dysbiosis through the growth of periodontal pathogens such as demonstrated for P. gingivalis under low hemin bioavailability. An individual’s diet also defines the consortium of microbial communities that take up residency in the oral and gastrointestinal (GI) tract microbiomes. Their imbalance can lead to behavioral changes. For example, probiotics enriched in Lactobacillus genus of bacteria, when ingested, exert some anti-inflammatory influence through common host/bacterial neurochemicals, both locally, and through sensory signaling back to the brain. Early life dietary behaviors may cause an imbalance in the host/microbial endocrinology through a dietary intake incompatible with a healthy GI tract microbiome later in life. This imbalance in host/microbial endocrinology may have a lasting impact on mental health. This observation opens up an opportunity to explore the mechanisms, which may underlie the previously detected relationship between diet, oral/GI microbial communities, to anxiety, cognition and sleep

    The Clinical and Translational Science Awards (CTSA) program represents a significant public investment. To realize its major goal of improving the public’s health and reducing health disparities, the CTSA Consortium’s Community Engagement Key Function Committee has undertaken the challenge of developing a taxonomy of community health indicators. The objective is to initiate a unified approach for monitoring progress in improving population health outcomes. Such outcomes include, importantly, the interests and priorities of community stakeholders, plus the multiple, overlapping interests of universities and of the public health and health care professions involved in the development and use of local health care indicators. The emerging taxonomy of community health indicators that the authors propose supports alignment of CTSA activities and facilitates comparative effectiveness research across CTSAs, thereby improving the health of communities and reducing health disparities. The proposed taxonomy starts at the broadest level, determinants of health; subsequently moves to more finite categories of community health indicators; and, finally, addresses specific quantifiable measures. To illustrate the taxonomy’s application, the authors have synthesized 21 health indicator projects from the literature and categorized them into international, national, or local/special jurisdictions. They furthered categorized the projects within the taxonomy by ranking indicators with the greatest representation among projects and by ranking the frequency of specific measures. They intend for the taxonomy to provide common metrics for measuring changes to population health and, thus, extend the utility of the CTSA Community Engagement Logic Model. The input of community partners will ultimately improve population health. PMID:24556775

    The choice of bedding material affects the quality of air in a stable and, consequently, the respiratory health of horses and humans. The risk of respiratory problems can be mitigated by improving the quality of air in the stable. The choice of bedding material is particularly important in cold climate conditions where horses are kept indoors throughout the year. This study examined the impact of three bedding materials: straw (S), peat with shavings (PS), and crushed wood pellets (CWP). The investigated factors were air contamination, including dust contamination and microbial (bacterial and fungal) contamination, and the condition of the equine respiratory tract. The condition of the respiratory tract was evaluated based on the results of arterial blood biochemistry tests and endoscopic evaluations of the upper respiratory tract. Mechanical dust contamination was lowest for PS (1.09mg/m 3 ) and highest for CWP (4.07mg/m 3 ). Bacterial contamination (in CFU - colony forming units) was highest for PS (5.14log 10 CFU/m 3 ) and lowest for CWP (4.81log 10 CFU/m 3 ). Fungal air contamination was lowest for CWP (4.54log 10 CFU/m 3 ) and highest for S (4.82log 10 CFU/m 3 ) and PS (4.88log 10 CFU/m 3 ). An analysis of physiological indicators revealed that all horses were clinically healthy regardless of the type of applied bedding. The type of bedding material did not exert a clear influence on arterial blood biochemistry or the results of endoscopic evaluations of the respiratory tract; however, the use of alternative for straw bedding materials improved endoscopy results.

    We provide original, international evidence documenting that self-assessed health (SAH) is a leading health indicator, that is, a significant predictor of future changes in health conditions, in a large sample of Europeans aged above 50 and living in 13 different countries. We find that, after controlling for attrition bias, lagged SAH is significantly and negatively correlated with changes in the number of chronic diseases, net of the correlations with levels, and changes in sociodemographic factors and health styles, country and regional health system effects, and declared symptoms. Illness-specific estimates document that lagged SAH significantly correlates with arthritis, cholesterol, and lung diseases (and weakly so with ulcer, hypertension, and cataracts) and has a significant correlation with the probability of contracting cancer. Interpretations and policy implications of our findings are discussed in the paper. Copyright © 2017 John Wiley & Sons, Ltd.

    The role climate change may play in altering human health, particularly in the emergence and spread of diseases, is an evolving area of research. It is important to understand this relationship because it will compound the already significant burden of diseases on national economies and public health. Authorities need to be able to assess, anticipate, and monitor human health vulnerability to climate change, in order to plan for, or implement action to avoid these eventualities. Environmental health indicators (EHIs) provide a tool to assess, monitor, and quantify human health vulnerability, to aid in the design and targeting of interventions, and measure the effectiveness of climate change adaptation and mitigation activities. Our aim was to identify the most suitable framework for developing EHIs to measure and monitor the impacts of climate change on human health and inform the development of interventions. Using published literature we reviewed the attributes of 11 frameworks. We identified the Driving force-Pressure-State-Exposure-Effect-Action (DPSEEA) framework as the most suitable one for developing EHIs for climate change and health. We propose the use of EHIs as a valuable tool to assess, quantify, and monitor human health vulnerability, design and target interventions, and measure the effectiveness of climate change adaptation and mitigation activities. In this paper, we lay the groundwork for the future development of EHIs as a multidisciplinary approach to link existing environmental and epidemiological data and networks. Analysis of such data will contribute to an enhanced understanding of the relationship between climate change and human health. PMID:21845162

    To compare self-perceived health indicators between ethnic groups in Colombia. Cross-sectional study with data from the 2007 National Public Health Survey (ENSP-2007). Data from 57,617 people ≥18 years were used. Variables included: belonging to an ethnic group (exposure); self-rated health; mental health problems, injuries for accidents/violence (outcomes); sex, age, education level and occupation (explicative/control). A descriptive study was carried out of the explicative variables, and the prevalence of the outcomes was calculated according to ethnicity, education level and occupation. The association between the exposure variable and the outcomes was estimated by means of adjusted odds ratios (OR) with 95% CI using logistic regression. Analyses were conducted separately for men and women. The prevalence of outcomes was higher in people reporting to belong to an ethnic group and differences were found by sex, ethnic groups and health outcomes. Women from the Palenquero group were more likely to report poor self-rated health (aOR 7.04; 95%CI 2.50-19.88) and injuries from accidents/violence (aOR 7.99; 95%CI 2.89-22.07). Indigenous men were more likely to report mental health problems (aOR 1.75; 95%CI 1.41-2.17). Gradients according to ethnicity, education, occupation and sex were found. Minority ethnic groups are vulnerable to reporting poor health outcomes. Political actions are required to diminish health inequalities in these groups.

  9. The human microbiota: the role of microbial communities in health and disease

    Full Text Available During the last decade, there has been increasing awareness of the massive number of microorganisms, collectively known as the human microbiota, that are associated with humans. This microbiota outnumbers the host cells by approximately a factor of ten and contains a large repertoire of microbial genome-encoded metabolic processes. The diverse human microbiota and its associated metabolic potential can provide the host with novel functions that can influence host health and disease status in ways that still need to be analyzed. The microbiota varies with age, with features that depend on the body site, host lifestyle and health status. The challenge is therefore to identify and characterize these microbial communities and use this information to learn how they function and how they can influence the host in terms of health and well-being. Here we provide an overview of some of the recent studies involving the human microbiota and about how these communities might affect host health and disease. A special emphasis is given to studies related to tuberculosis, a disease that claims over one million lives each year worldwide and still represents a challenge for control in many countries, including Colombia.

    Universal Health Coverage (UHC) is widely considered one of the key components for the post-2015 health goal. The idea of UHC is rooted in the right to health, set out in the International Covenant on Economic, Social, and Cultural Rights. Based on the Covenant and the General Comment of the Committee on Economic, Social, and Cultural Rights, which is responsible for interpreting and monitoring the Covenant, we identify 6 key legal principles that should underpin UHC based on the right to health: minimum core obligation, progressive realization, cost-effectiveness, shared responsibility, participatory decision making, and prioritizing vulnerable or marginalized groups. Yet, although these principles are widely accepted, they are criticized for not being specific enough to operationalize as post-2015 indicators for reaching the target of UHC. In this article, we propose measurable and achievable indicators for UHC based on the right to health that can be used to inform the ongoing negotiations on Sustainable Development Goals. However, we identify 3 major challenges that face any exercise in setting indicators post-2015: data availability as an essential criterion, the universality of targets, and the adaptation of global goals to local populations. © SAGE Publications 2015.

    All 16 KPIs were analyzed, including the percentage of patients admitted to the stroke unit, venous thromboembolism prophylaxis in the first 48 hours after admission, pneumonia and hospital mortality due to stroke, and hospital discharge on antithrombotic therapy in patients without cardioembolic mechanism. Both centers admitted over 80% of the patients in their stroke unit. The incidence of venous thromboembolism prophylaxis was > 85%, that of in-hospital pneumonia was 70%. Our results suggest using the parameters of all of the 16 KPIs required by the Ministry of Health of Brazil, and the present results for the two stroke units for future benchmarking.

  13. Flavin as an Indicator of the Rate-Limiting Factor for Microbial Current Production in Shewanella oneidensis MR-1

    Microbial electrode catalysis such as microbial fuel cells or electrosynthesis involves electron exchange with the electrodes located at the cell exterior; i.e., extracellular electron transport (EET). Despite the vast amount of research on the kinetics of EET to optimize the catalysis rate, the relevance of other factors, including upstream metabolic reactions, has scarcely been investigated. Herein, we report an in vivo electrochemical assay to confirm whether EET limits anodic current production (j) for the lactate oxidation of Shewanella oneidensis MR-1. Addition of riboflavin, which specifically enhances the EET rate, increased j only in the early phase before j saturation. In contrast, when we removed a trace metal ion necessary for upstream reactions from the electrolyte, a significant decrease in j and the lactate consumption rate was observed only after j saturation. These data suggest that the limiting factor for j shifted from EET to upstream reactions, highlighting the general importance of enhancing, for example, microbial metabolism, especially for long-standing practical applications. Our concept to specifically control the rate of EET could be applicable to other bioelectrode catalysis systems as a strategy to monitor their rate-limiting factors.

    Few studies have assessed healthcare experiences in apparently healthy adolescents, or whether healthcare attitudes are linked to the two leading adolescent health indicators, smoking and obesity. Even fewer have examined these relationships in adolescent immigrant groups or made comparisons to adolescent non-immigrants. Using a cross-sectional study, healthcare experiences were compared among three groups of adolescents (n = 589) including Russian immigrants (n = 154), Ethiopian immigrants (n = 54), and non-immigrants (n = 381). Bootstrap estimates indicated positive healthcare experiences were less common among Russian adolescent immigrants (OR = 0.38, CI = 0.17, 0.86) compared to non-immigrants, unless the Russian adolescent immigrants reported above average socioeconomic status, in which case they were more likely than non-immigrant adolescents to report positive healthcare experiences (OR = 3.22, CI = 1.05, 9.85). Positive healthcare experiences were less likely among adolescents who were smokers (OR = 0.50, CI = 0.27, 0.91), and more likely for adolescents with a normal or low BMI (OR = 3.16, CI = 1.56, 6.40) and for those relying on parents for health information (OR = 1.97, CI = 1.05, 3.70). Findings suggest a social gradient in which positive healthcare experiences were more common among adolescence with higher socioeconomic status for some immigrants (Russian adolescents) but not for others. The two leading health indicators were related to healthcare experiences, but as adolescent smokers were less likely to have positive healthcare experiences, proactive efforts are needed to engage this group. What is Known: • Health indicators (such as obesity) and healthcare attitudes are linked to healthcare service use among adolescents sampled from outpatient and inpatient populations. What is New: • A social gradient involving socioeconomic status and being an adolescent immigrant was found regarding

    Full Text Available Anthropometric indices are of the best indicators for growth monitoring during neonatal period. The aim of this cross-sectional study was to determine the association ofanthropometric indices in Iranian and Afghan infants with maternal indices. The study was conducted in 230 mothers who had health profiles in the Eqbaliyeh health center, Qazvin during 2013. Data were collected through the records in mothers’ health profiles. Data were analyzed using T-test and Pearson’s correlation coefficient. Of 230 infants, 119 (51.7% were male. Mean weight and head circumference were significantly different between Iranian and Afghan infants.The Iranian mothers were older and had higher weight and height during pregnancy compared to the Afghan mothers and the difference was statistically significant. There was positive significant correlation between mothers’ age, weight, hemoglobin, and hematocrit and infants’ birth weight. There was also positive significant correlation between mothers’ hemoglobin and hematocrit and infants’ height. With regards to the results, proper nutrition, maternal health, and providing appropriate health services during pregnancy can be beneficial for improving infants’ health.

    Objective To evaluate the evolution of indicators after the implementation of 21 Oral Healthcare Teams in the Family Health Strategy. Methods We used data from outpatient services of Oral Healthcare Teams to evaluate efficiency, access, percentage of absences and emergencies of oral healthcare professionals who worked in the partnership between the Sociedade Beneficente Israelita Brasileira Hospital Albert Einstein and the Secretaria Municipal de Saúde de São Paulo, during the period 2009-2011. Results Percentages of emergencies, income, and access showed a significant difference during the period analyzed, but no difference for percentage of absences was found. When monthly analysis was made, it is noteworthy that at the beginning of service implementation a fluctuation occurred, which may indicate that the work was consolidated over the months, becoming capable of receiving new professionals and increasing the population served. Comparison of the indicators in that period with the goals agreed upon between the Sociedade Beneficente Israelita Brasileira Hospital Albert Einstein and the Secretaria Municipal de Saúde de São Paulo made it possible to notice that the Oral Health Teams had a good performance. Conclusion The results showed that the goals were achieved reflecting the increasing number of professionals, the maturing of work processes in the Oral Health Teams, and optimization of the manpower available to perform the activities. Understanding these results will be important to guide the actions of Oral Health Teams for the following years and to assess the achievement of goals. PMID:25295445

    The National Social Life, Health, and Aging Project (NSHAP) measures seven indicators of quality of life (QoL) and psychological health. The measures used for happiness, self-esteem, depression, and loneliness are well established in the literature. Conversely, measures of anxiety, stress, and self-reported emotional health were modified for their use in this unique project. The purpose of this paper is to provide (a) an overview of NSHAP's QoL assessment and (b) evidence for the adequacy of the modified measures. First, we examined the psychometric properties of the modified measures. Second, the established QoL measures were used to examine the concurrent validity of the modified measures. Finally, gender- and age-group differences were examined for each modified measure. The anxiety index exhibited good internal reliability and concurrent validity. Consistent with the literature, a single-factor structure best fit the data. Stress was satisfactory in terms of concurrent validity but with only fair internal consistency. Self-reported emotional health exhibited good concurrent validity and moderate external validity. The modified indices used in NSHAP tended to exhibit good internal reliability and concurrent validity. These measures can confidently be used in the exploration of QoL and psychological health in later life and its many correlates.

    Amplicon length heterogeneity PCR (LH-PCR) was investigated for its ability to distinguish between microbial community patterns from the same soil type under different land management practices. Natural sagebrush and irrigated mouldboard-ploughed soils from Idaho were queried as to which hypervariable domains, or combinations of 16S rRNA gene domains, were the best molecular markers. Using standard ecological indices to measure richness, diversity and evenness, the combination of three domains, V1, V3 and V1+V2, or the combined V1 and V3 domains were the markers that could best distinguish the undisturbed natural sagebrush communities from the mouldboard-ploughed microbial communities. Bray-Curtis similarity and multidimensional scaling were found to be better metrics to ordinate and cluster the LH-PCR community profiling data. The use/misuse of traditional ecological indices such as diversity and evenness to study microbial community profiles will remain a major point to consider when performing metagenomic studies.

    There is accumulating evidence that the emerging burden of global climate change threatens the fidelity of routine indicators for disease detection and management of risks to public health. The threat partially reflects the conservative character of the health sector and the reluctance to adopt new indicators, despite the growing awareness that existing environmental health indicators were developed to respond to risks that may no longer be relevant, and are too simplistic to also act as indicators for newer global-scale risk factors. This study sought to understand the scope of existing health indicators, while aiming to discover new indicators for building resilience against three climate sensitive diseases (cerebro spinal meningitis, malaria and diarrhea). Therefore, new potential indicators derived from human and biophysical origins were developed to complement existing health indicators, thereby creating climate-sensitive battery of robust composite indices of resilience in health planning. Using Ghana's health sector as a case study systematic international literature review, national expert consultation, and focus group outcomes yielded insights into the relevance, sensitivity and impacts of 45 indicators in 11 categories in responding to climate change. In total, 65% of the indicators were sensitive to health impacts of climate change; 24% acted directly; 31% synergistically; and 45% indirectly, with indicator relevance strongly associated with type of health response. Epidemiological indicators (e.g. morbidity) and health demographic indicators (e.g. population structure) require adjustments with external indicators (e.g. biophysical, policy) to be resilient to climate change. Therefore, selective integration of social and ecological indicators with existing public health indicators improves the fidelity of the health sector to adopt more robust planning of interdependent systems to build resilience. The study highlights growing uncertainties in

    This study aimed to investigate health belief as a major motive for diet and lifestyle behaviors of 100 vegans in the United States; and to determine congruence with selected health and nutrition outcomes. Response data from an administered questionnaire was analyzed. Statistical analyses determined the most common factors influencing diet choice; the number of vegans practicing particular lifestyle behaviors; body mass index; and prevalence of self-reported chronic disease diagnoses. Nutrient intakes were analyzed and assessed against Dietary Reference Intakes. Health was the most reported reason for diet choice (47%). In the health belief, animal welfare, and religious/other motive categories, low percentages of chronic disease diagnoses were reported: 27%, 11%, and 15%, respectively. There were no significant differences in health behaviors and indices among vegan motive categories, except for product fat content choices. Within the entire study population, health-related vegan motive coincided with regular exercise; 71% normal BMI (mean=22.6); minimal alcohol and smoking practices; frequently consumed vegetables, nuts, and grains; healthy choices in meal types, cooking methods, and low-fat product consumption; and adequate intakes for most protective nutrients when compared to reference values. But incongruence was found with 0% intake adequacy for vitamin D; and observation of excessive sodium use. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the soil use and management within a desired timescale. Attributes with a rapid response to natural or anthropogenic actions are considered good indicators of soil health. Among the physical indicators, soil texture, aggregation, moisture, porosity, and bulk density have been used, while among chemical indicators total C and N, mineral nutrients, organic matter, cation exchange capacity, among others are well established. However, most of them generally have a slow response, when compared to the biological ones, such as microbial biomass C and N, biodiversity, soil enzymes, soil respiration, etc., in addition to macro and mesofauna. Thus, a systemic approach based on different kinds of indicators (physical, chemical and biological in assessing soil health would be safer than using only one kind of attribute. Many human activities have caused desertification, loss of biodiversity, disruption of aggregates, loss of organic matter and nutrients, among others. Today, it is imperious to maintain soil health and productivity with increasing emphasis on reforestation and recuperation of degraded areas through the use of organic amendments, reintroduction of plants, soil fauna and microorganisms. This review focused on an integrative view on indicators of soil health to be used as tools for prediction of sustainability in production systems.

  9. Interactions with human nutrition and other indices of population health

    The contamination of food is an important pathway involved in the internal combination of humans. The site-related critical foodstuffs can be grouped into three main categories: dairy products; aquatic animals, such as fish, molluscs and crustaceans; and other typical foods. The concentration factor plays a more important role than the amount of a certain food consumed. Semi-natural and natural ecosystems are of special interest in this content because they can provide critical pathways for radionuclide transfer to humans, and they can also act as temporary sinks or long-term sources for radionuclides deposited from the atmosphere. From the viewpoint of population health, another important role is played by the countermeasures. The reference values commonly adopted in radiation protection are conservative and they have been established for planning practices that could provide future sources of irradiation. After a large release of radionuclides, the evaluation of the problem must be as realistic as possible, otherwise the countermeasures will imply consequences worse than those produced by the accident itself (without any further intervention). This criterion was clearly stated by the International Commission on Radiological Protection but it was frequently neglected after the Chernobyl accident. The results of a survey on the number of induced abortions following this incident are reported. These suggest that moral and ethical problems are involved above and beyond any economical implications. (Author)

    The effect of lead (Pb) treatment on the soil enzymatic activities, soil microbial biomass, rice physiological indices and rice biomass were studied in a greenhouse pot experiment. Six levels of Pb viz. 0(CK), 100, 300, 500, 700, 900 mg/kg soil were applied in two types of paddy soils. The results showed that Pb treatment had a stimulating effect on soil enzymatic activities and microbial biomass carbon (Cmic) at low concentration and an inhibitory influence at higher concentration. The degree of influence on enzymatic activities and Cmic by Pb was related to the clay and organic matter contents of the soils. When the Pb treatment was raised to the level of 500 mg/kg, ecological risk appeared both to soil microorganisms and plants. The results also revealed a consistent trend of increased chlorophyll contents and rice biomass initially, maximum at a certain Pb treatment, and then decreased gradually with the increase in Pb concentration. Pb was effective in inducing proline accumulation and its toxicity causes oxidative stress in rice plants. Therefore, it was concluded that soil enzymatic activities, Cmic and rice physiological indices, could be sensitive indicators to reflect environmental stress in soil-lead-rice system.

    The effect of a stormwater conveyance system on indicator bacteria levels at a Florida beach was assessed using microbial source tracking methods, and by investigating indicator bacteria population structure in water and sediments. During a rain event, regulatory standards for both fecal coliforms and Enterococcus spp. were exceeded, contrasting with significantly lower levels under dry conditions. Indicator bacteria levels were high in sediments under all conditions. The involvement of human sewage in the contamination was investigated using polymerase chain reaction (PCR) assays for the esp gene of Enterococcus faecium and for the conserved T antigen of human polyomaviruses, all of which were negative. BOX-PCR subtyping of Escherichia coli and Enterococcus showed higher population diversity during the rain event; and higher population similarity during dry conditions, suggesting that without fresh inputs, only a subset of the population survives the selective pressure of the secondary habitat. These data indicate that high indicator bacteria levels were attributable to a stormwater system that acted as a reservoir and conduit, flushing high levels of indicator bacteria to the beach during a rain event. Such environmental reservoirs of indicator bacteria further complicate the already questionable relationship between indicator organisms and human pathogens, and call for a better understanding of the ecology, fate and persistence of indicator bacteria.

    Taiwan is surrounded by oceans, and therefore numerous pleasure beaches attract millions of tourists annually to participate in recreational swimming activities. However, impaired water quality because of fecal pollution poses a potential threat to the tourists' health. This study probabilistically characterized the health risks associated with recreational swimming engendered by waterborne enterococci at 13 Taiwanese beaches by using quantitative microbial risk assessment. First, data on enterococci concentrations at coastal beaches monitored by the Taiwan Environmental Protection Administration were reproduced using nonparametric Monte Carlo simulation (MCS). The ingestion volumes of recreational swimming based on uniform and gamma distributions were subsequently determined using MCS. Finally, after the distribution combination of the two parameters, the beta-Poisson dose-response function was employed to quantitatively estimate health risks to recreational swimmers. Moreover, various levels of risk to recreational swimmers were classified and spatially mapped to explore feasible recreational and environmental management strategies at the beaches. The study results revealed that although the health risks associated with recreational swimming did not exceed an acceptable benchmark of 0.019 illnesses daily at all beaches, they approached to this benchmark at certain beaches. Beaches with relatively high risks are located in Northwestern Taiwan owing to the current movements.

    Full Text Available Introduction: Accumulated data obtained over the last 20 years on the microbial status and survival of pathogens on currency notes indicate that this could represent a potential cause of sporadic cases of food borne illness. Objectives: To identify the micro-organisms present on the Indian currency notes and the oral health risks due to microbial contamination of Indian currency notes circulating in Bengaluru city. Materials and Methods: A cross-sectional survey was conducted and the Indian currency notes of various denominations (Rs. 10, Rs. 20, Rs. 50, Rs. 100, Rs. 500, and Rs. 1000 were collected from fruit vendors, hawkers, vegetable vendors, bus conductors, railway ticket counters, hotel counters, and butchers. Sample size was determined to be 70 Indian currency notes. Convenience sampling technique was used. Microbiological analysis of the collected currency notes was done. Results: The contamination rate of collected currency notes from the butchers and hawkers were 80% and 60% respectively. Staphylococcus aureus was present on 15 currency notes (21.42% and was found to be higher in Rs. 10 than in other currency denominations. Streptococcus pyogenes was present on four currency notes (5.714% of Rs. 10. Conclusion: The Indian currency notes circulating in Bengaluru city were contaminated with pathogenic bacteria. The oral health risks due to microbial contamination of Indian currency notes are acute pharyngitis, peritonsillar or retropharyngeal abscess, mastoiditis, sinusitis, otitis media, mild cellulitis, angular cheilitis, some endodontic infections, osteomyelitis of the jaw, parotitis, and oral mucositis.

    A high biomasses of Cladophora, a filamentous green alga, is found mainly during the summer along the shores of Lake Michigan. In this study, the abundance and persistence of the fecal indicator bacterium Escherichia coli and sulfate-reducing bacteria (SRB) on Cladophora mats collected at Lake Michigan beaches were evaluated using both culture-based and molecular analyses. Additionally, 16S rRNA gene cloning and sequencing were used to examine the bacterial community composition. Overall, E. coli was detected in all 63 samples obtained from 11 sites, and the average levels at most beaches ranged from 2,700 CFU/100 g (wet weight) of Cladophora to 7,500 CFU/100 g of Cladophora. However, three beaches were found to have site average E. coli densities of 12,800, 21,130, and 27,950 CFU/100 g of Cladophora. The E. coli levels in the lake water collected at the same time from these three sites were less than the recommended U.S. Environmental Protection Agency limit, 235 CFU/100 ml. E. coli also persisted on Cladophora mats in microcosms at room temperature for more than 7 days, and in some experiments it persisted for as long as 28 days. The SRB densities on Cladophora mats were relatively high, ranging from 4.4x10(6) cells/g (6.64 log CFU/g) to 5.73x10(6) cells/g (6.76 log CFU/g) and accounting for between 20% and 27% of the total bacterial counts. Partial sequences of the 16S rRNA gene clones revealed a phylogenetically diverse community, in which the Cytophaga-Flavobacterium-Bacteroides cluster and the low-G+C-content gram-positive bacteria were the dominant organisms, accounting for 40% and 12.8%, respectively, of the total clone library. These results further reveal the potential public health and ecological significance of Cladophora mats that are commonly found along the shoreline of Lake Michigan, especially with regard to the potential to harbor microorganisms associated with fecal pollution and odor-causing bacteria.

  15. Microbial pathways in colonic sulfur metabolism and links with health and disease

    Full Text Available Sulfur is both crucial to life and a potential threat to health. While colonic sulfur metabolism mediated by eukaryotic cells is relatively well studied, much less is known about sulfur metabolism within gastrointestinal microbes. Sulfated compounds in the colon are either of inorganic (e.g., sulfates, sulfites or organic (e.g., dietary amino acids and host mucins origin. The most extensively studied of the microbes involved in colonic sulfur metabolism are the sulfate-reducing bacteria, which are common colonic inhabitants. Many other microbial pathways are likely to shape colonic sulfur metabolism as well as the composition and availability of sulfated compounds, and these interactions need to be examined in more detail. Hydrogen sulfide is the sulfur derivative that has attracted the most attention in the context of colonic health, and the extent to which it is detrimental or beneficial remains in debate. Several lines of evidence point to sulfate-reducing bacteria or exogenous hydrogen sulfide as potential players in the etiology of intestinal disorders, inflammatory bowel diseases and colorectal cancer in particular. Generation of hydrogen sulfide via pathways other than dissimilatory sulfate reduction may be as, or more, important than those involving the sulfate-reducing bacteria. We suggest here that a novel axis of research is to assess the effects of hydrogen sulfide in shaping colonic microbiome structure. Clearly, in-depth characterization of the microbial pathways involved in colonic sulfur metabolism is necessary for a better understanding of its contribution to colonic disorders and development of therapeutic strategies.

    Full Text Available Abstract Background Many definitions are being used to conceptualize child health problems. With survey data, commonly used indicators for identifying children with health problems have included chronic condition checklists, measures of activity limitations, elevated service use, and health utility thresholds. This study compares these different indicators in terms of the prevalence rates elicited, and in terms of how the subgroups identified differ. Methods Secondary data analyses used data from the National Longitudinal Survey of Children and Youth, which surveyed a nationally representative sample of Canadian children (n = 13,790. Descriptive analyses compared healthy children to those with health problems, as classified by any of the key indicators. Additional analyses examined differences between subgroups of children captured by a single indicator and those described as having health problems by multiple indicators. Results This study demonstrates that children captured by any of the indicators had poorer health than healthy children, despite the fact that over half the sample (52.2% was characterized as having a health problem by at least one indicator. Rates of child ill health differed by indicator; 5.6% had an activity limitation, 9.2% exhibited a severe health difficulty, 31.7% reported a chronic condition, and 36.6% had elevated service use. Further, the four key indicators captured different types of children. Indicator groupings differed on child and socio-demographic factors. Compared to children identified by more than one indicator, those identified only by the severe health difficulty indicator displayed more cognitive problems (p Conclusion We provide information useful to researchers when selecting indicators from survey data to identify children with health problems. Researchers and policy makers need to be aware of the impact of such definitions on prevalence rates as well as on the composition of children classified as

    Public health indicators generally operate in the world as credible, apolitical and authoritative. But indicators are less stable than they appear. Clinical critiques of Intrauterine Growth Restriction (IUGR) criteria have been forthcoming for decades. This article, though, takes up the measuring and calculation gradients of IUGR in the ultrasound machine itself, including the software algorithms that identify IUGR. One hospital where research was conducted incorrectly predicted pathological birth outcomes 14 of 14 times. We are at a historical moment when the global use of prenatal diagnostic ultrasound for the express purpose of assessing IUGR is set to escalate. Medical imaging device corporations like Siemens, Toshiba, General Electric and Phillips are quite literally banking on it, and new forms of ultrasound technology and diagnostic software are increasingly available on smartphones, tablets and laptops. Clinical guidelines for IUGR--assumed to be authoritative and evidence-based--are evolving right along with the installation throughout the world of the technology capable of diagnosing it. Maternal malnutrition remains the single strongest predictive factor for IUGR, regardless of the technological investments currently amassing to identify the indicator, which is cause for a reassessment of priority spending and investment.

    There is optimism that the inclusion of universal health coverage in the Sustainable Development Goals advances its prominence in global and national health policy. However, formulating indicators for Target 3.8 through the Inter-Agency Expert Group on Sustainable Development Indicators has been challenging. Achieving consensus on the conceptual and methodological aspects of universal health coverage is likely to take some time in multi-stakeholder fora compared with national efforts to select indicators.

    To provide indicators to assess the impact on health, its social determinants and health inequalities from a social context and the recent economic recession in Spain and its autonomous regions. Based on the Spanish conceptual framework for determinants of social inequalities in health, we identified indicators sequentially from key documents, Web of Science, and organisations with official statistics. The information collected resulted in a large directory of indicators which was reviewed by an expert panel. We then selected a set of these indicators according to geographical (availability of data according to autonomous regions) and temporal (from at least 2006 to 2012) criteria. We identified 203 contextual indicators related to social determinants of health and selected 96 (47%) based on the above criteria; 16% of the identified indicators did not satisfy the geographical criteria and 35% did not satisfy the temporal criteria. At least 80% of the indicators related to dependence and healthcare services were excluded. The final selection of indicators covered all areas for social determinants of health, and 62% of these were not available on the Internet. Around 40% of the indicators were extracted from sources related to the Spanish Statistics Institute. We have provided an extensive directory of contextual indicators on social determinants of health and a database to facilitate assessment of the impact of the economic recession on health and health inequalities in Spain and its autonomous regions.

    Full Text Available Abstract Background The Federal Ministry of Health of Ethiopia has been publishing Health and Health related indicators of the country annually since 1987 E.C. These indicators have been of high importance in indicating the status of health in the country in those years. However, the trends/patterns of these indicators and the factors related to the trends have not yet been investigated in a systematic manner. In addition, there were minimal efforts to develop a model for predicting future values of Health and Health related indicators based on the current trend. Objectives The overall aim of this study was to analyze trends of and develop model for prediction of Health and Health related indicators. More specifically, it described the trends of Health and Health related indicators, identified determinants of mortality and morbidity indicators and developed model for predicting future values of MDG indicators. Methods This study was conducted on Health and Health related indicators of Ethiopia from the year 1987 E.C to 2000 E.C. Key indicators of Mortality and Morbidity, Health service coverage, Health systems resources, Demographic and socio-economic, and Risk factor indicators were extracted and analyzed. The trends in these indicators were established using trend analysis techniques. The determinants of the established trends were identified using ARIMA models in STATA. The trend-line equations were then used to predict future values of the indicators. Results Among the mortality indicators considered in this study, it was only Maternal Mortality Ratio that showed statistically significant decrement within the study period. The trends of Total Fertility Rate, physician per 100,000 population, skilled birth attendance and postnatal care coverage were found to have significant association with Maternal Mortality Ratio trend. There was a reversal of malaria parasite prevalence in 1999 E.C from Plasmodium Falciparum to Plasmodium Vivax. Based on

    Thermal adaptations of soil microorganisms could mitigate or facilitate global warming effects on soil organic matter (SOM) decomposition and soil CO2 efflux. We incubated soil from warmed and control subplots of a forest soil warming experiment to assess whether 9 years of soil warming affected the rates and the temperature sensitivity of the soil CO2 efflux, extracellular enzyme activities, microbial efficiency, and gross N mineralization. Mineral soil (0-10 cm depth) was incubated at temperatures ranging from 3 to 23 °C. No adaptations to long-term warming were observed regarding the heterotrophic soil CO2 efflux (R10 warmed: 2.31 ± 0.15 μmol m(-2)  s(-1) , control: 2.34 ± 0.29 μmol m(-2)  s(-1) ; Q10 warmed: 2.45 ± 0.06, control: 2.45 ± 0.04). Potential enzyme activities increased with incubation temperature, but the temperature sensitivity of the enzymes did not differ between the warmed and the control soils. The ratio of C : N acquiring enzyme activities was significantly higher in the warmed soil. Microbial biomass-specific respiration rates increased with incubation temperature, but the rates and the temperature sensitivity (Q10 warmed: 2.54 ± 0.23, control 2.75 ± 0.17) did not differ between warmed and control soils. Microbial substrate use efficiency (SUE) declined with increasing incubation temperature in both, warmed and control, soils. SUE and its temperature sensitivity (Q10 warmed: 0.84 ± 0.03, control: 0.88 ± 0.01) did not differ between warmed and control soils either. Gross N mineralization was invariant to incubation temperature and was not affected by long-term soil warming. Our results indicate that thermal adaptations of the microbial decomposer community are unlikely to occur in C-rich calcareous temperate forest soils. © 2015 The Authors.

  5. Theoretical investigation of the upper and lower bounds of a generalized dimensionless bearing health indicator

    2018-01-01

    Bearing-supported shafts are widely used in various machines. Due to harsh working environments, bearing performance degrades over time. To prevent unexpected bearing failures and accidents, bearing performance degradation assessment becomes an emerging topic in recent years. Bearing performance degradation assessment aims to evaluate the current health condition of a bearing through a bearing health indicator. In the past years, many signal processing and data mining based methods were proposed to construct bearing health indicators. However, the upper and lower bounds of these bearing health indicators were not theoretically calculated and they strongly depended on historical bearing data including normal and failure data. Besides, most health indicators are dimensional, which connotes that these health indicators are prone to be affected by varying operating conditions, such as varying speeds and loads. In this paper, based on the principle of squared envelope analysis, we focus on theoretical investigation of bearing performance degradation assessment in the case of additive Gaussian noises, including distribution establishment of squared envelope, construction of a generalized dimensionless bearing health indicator, and mathematical calculation of the upper and lower bounds of the generalized dimensionless bearing health indicator. Then, analyses of simulated and real bearing run to failure data are used as two case studies to illustrate how the generalized dimensionless health indicator works and demonstrate its effectiveness in bearing performance degradation assessment. Results show that squared envelope follows a noncentral chi-square distribution and the upper and lower bounds of the generalized dimensionless health indicator can be mathematically established. Moreover, the generalized dimensionless health indicator is sensitive to an incipient bearing defect in the process of bearing performance degradation.

  6. Using indicators to determine the contribution of human rights to public health efforts

    2009-01-01

    Abstract There is general agreement on the need to integrate human rights into health policies and programmes, although there is still reluctance to go beyond rhetorical acknowledgement of their assumed significance. To determine the actual value of human rights for the effectiveness of public health efforts requires clarity about what their incorporation looks like in practice and how to assess their contribution. Despite the pervasive use of indicators in the public health field, indicators that specifically capture human rights concerns are not well developed and those that exist are inconsistently used. Even though “health and human rights indicators” are increasingly being constructed, it is often the case that health indicators are used to draw conclusions about some interaction between human rights and health; or that law and policy or other indicators, traditionally the domain of the human rights community, are used to make conclusions about health outcomes. To capture the added value that human rights bring to health, the differences in the contributions offered by these indicators need to be understood. To determine the value of different measures for advancing programme effectiveness, improving health outcomes and promoting human rights, requires questioning the intended purpose behind the construction of an indicator, who uses it, the kind of indicator it is, the extent to which it provides information about vulnerable populations, as well as how the data are collected and used.

    This study aimed at investigating the microbial contamination of mobile phones in a hospital setting. Swab samples were collected from 40 mobile phones of patients and health care workers at the Alexandria University Students' Hospital. They were tested for their bacterial contamination at the microbiology laboratory of the High Institute of Public Health. Quantification of bacteria was performed using both surface spread and pour plate methods. Isolated bacterial agents were identified using standard microbiological methods. Methicillin-resistant Staphylococcus aureus was identified by disk diffusion method described by Bauer and Kirby. Isolated Gram-negative bacilli were tested for being extended spectrum beta lactamase producers using the double disk diffusion method according to the Clinical and Laboratory Standards Institute recommendations. All of the tested mobile phones (100%) were contaminated with either single or mixed bacterial agents. The most prevalent bacterial contaminants were methicillin-resistant S. aureus and coagulase-negative staphylococci representing 53% and 50%, respectively. The mean bacterial count was 357 CFU/ml, while the median was 13 CFU/ml using the pour plate method. The corresponding figures were 2,192 and 1,720 organisms/phone using the surface spread method. Mobile phones usage in hospital settings poses a risk of transmission of a variety of bacterial agents including multidrug-resistant pathogens as methicillin-resistant S. aureus. The surface spread method is an easy and useful tool for detection and estimation of bacterial contamination of mobile phones.

    The economic crisis has adverse effects on determinants of health and health inequalities. The aim of this article was to present a set of indicators of health and its determinants to monitor the effects of the crisis in Spain. On the basis of the conceptual framework proposed by the Commission for the Reduction of Social Health Inequalities in Spain, we searched for indicators of social, economic, and political (structural and intermediate) determinants of health, as well as for health indicators, bearing in mind the axes of social inequality (gender, age, socioeconomic status, and country of origin). The indicators were mainly obtained from official data sources published on the internet. The selected indicators are periodically updated and are comparable over time and among territories (among autonomous communities and in some cases among European Union countries), and are available for age groups, gender, socio-economic status, and country of origin. However, many of these indicators are not sufficiently reactive to rapid change, which occurs in the economic crisis, and consequently require monitoring over time. Another limitation is the lack of availability of indicators for the various axes of social inequality. In conclusion, the proposed indicators allow for progress in monitoring the effects of the economic crisis on health and health inequalities in Spain. Copyright © 2013 SESPAS.

    This article describes the activities of a project aimed at developing a system of process and process/outcome indicators suitable to monitor over time the quality of psychiatric care of Italian inpatient and residential psychiatric facilities. This system, named PRISM (Process Indicator System for Mental health), was developed by means of a standardized evaluation made by a panel of experts and a consecutive pilot study in 17 inpatient and 13 residential psychiatric facilities. A total of 28 indicators were selected from a set of 251 candidate indicators developed by the most relevant and qualified Italian and international authorities. These indicators are derived by data from medical records and information about characteristics of facilities, and they cover processes of care, operational equipment of facilities, staff training and working, relationships with external agencies, and sentinel events. The procedure followed for the development of the indicator system was reliable and innovative. The data collected from the pilot study suggested a favourable benefit-cost ratio between the workload associated with regular use of the indicators into the context of daily clinical activities and the advantages related to the information gathered through regular use of the indicators. CONCLUSIONS.:The PRISM system provides additional information about the healthcare processes with respect to the information gathered via routine information systems, and it might prove useful for both continuous quality improvement programs and health services research.

    Phytostabilization is a promising option for the remediation of metal contaminated soils which requires the implementation of long-term monitoring programs. We here propose to incorporate the paradigm of "adaptive monitoring", which enables monitoring programs to evolve iteratively as new information emerges and research questions change, to metal phytostabilization. Posing good questions that cover the chemical, toxicological and ecological concerns associated to metal contaminated soils is critical for an efficient long-term phytostabilization monitoring program. Regarding the ecological concerns, soil microbial parameters are most valuable indicators of the effectiveness of metal phytostabilization processes in terms of recovery of soil health. We suggest to group soil microbial parameters in higher-level categories such as "ecological attributes" (vigor, organization, stability) or "ecosystem services" in order to facilitate interpretation and, most importantly, to provide long-term phytostabilization monitoring programs with the required stability through time against changes in techniques, methods, interests, etc. that will inevitably occur during the monitoring program. Finally, a Phytostabilization Monitoring Card, based on both ecological attributes and ecosystem services, for soil microbial properties is provided.

    Converging evidence from culturally diverse contexts indicates that sexually explicit media use behavior (SEMB; i.e., pornography consumption) is associated with risky sexual health perceptions and behaviors, many that involve high risks of HIV/STD transmission. Essentially unexplored, and the focus here, are potential relationships between SEMB and nonsexual mental- and physical-health indicators. Variability in six continuously measured health indicators (depressive symptoms, mental- and physical-health diminished days, health status, quality of life, and body mass index) was examined across two levels (users, nonusers) of SEMB. A sample of 559 Seattle-Tacoma Internet-using adults was surveyed in 2006. Multivariate general linear models parameterized in a SEMB by respondent gender (2 × 2) factorial design were computed incorporating adjustments for several demographics. SEMB was reported by 36.7% (n = 205) of the sample. Most SEMB users (78%) were men. After adjusting for demographics, SEMB users, compared to nonusers, reported greater depressive symptoms, poorer quality of life, more mental- and physical-health diminished days, and lower health status. The findings show that mental- and physical-health indicators vary significantly across SEMB, suggesting the value of incorporating these factors in future research and programmatic endeavors. In particular, the findings suggest that evidence-based sexual health promotion strategies simultaneously addressing individuals' SEMB and their mental health needs might be a useful approach to improve mental health and address preventable sexual health outcomes associated with SEMB. © 2010 International Society for Sexual Medicine.

    We have developed a microtiter plate method for screening a large number of bacterial isolates for the ability to grow on different crystalline polycyclic aromatic hydrocarbons (PAHs). Growth on PAHs cannot easily be determined with standard growth assays because of the very low aqueous solubility and bioavailability of the PAHs. Our microtiter plate assay utilizes a new water-soluble respiration indicator, WST-1 {4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate}...

    This study aimed to develop a methodological tool to analyze and monitor the green jobs in the context of Occupational Health and Safety. A literature review in combination with an investigation of Occupational Health Indicators was performed. The resulting tool of Occupational Health Indicators was based on the existing information of "Single Report" and was validated by national's experts. The tool brings together 40 Occupational Health Indicators in four key fields established by World Health Organization in their conceptual framework "Health indicators of sustainable jobs." The tool proposed allows for assessing if the green jobs enabled to follow the principles and requirements of Occupational Health Indicators and if these jobs are as good for the environment as for the workers' health, so if they can be considered quality jobs. This shows that Occupational Health Indicators are indispensable for the assessment of the sustainability of green jobs and should be taken into account in the definition and evaluation of policies and strategies of the sustainable development.

    Full Text Available Introduction: The Mental Health Strategy for Canada identified a need to enhance the collection of data on mental health in Canada. While surveillance systems on mental illness have been established, a data gap for monitoring positive mental health and its determinants was identified. The goal of this project was to develop a Positive Mental Health Surveillance Indicator Framework, to provide a picture of the state of positive mental health and its determinants in Canada. Data from this surveillance framework will be used to inform programs and policies to improve the mental health of Canadians. Methods: A literature review and environmental scan were conducted to provide the theoretical base for the framework, and to identify potential positive mental health outcomes and risk and protective factors. The Public Health Agency of Canada’s definition of positive mental health was adopted as the conceptual basis for the outcomes of this framework. After identifying a comprehensive list of risk and protective factors, mental health experts, other governmental partners and non-governmental stakeholders were consulted to prioritize these indicators. Subsequently, these groups were consulted to identify the most promising measurement approaches for each indicator. Results: A conceptual framework for surveillance of positive mental health and its determinants has been developed to contain 5 outcome indicators and 25 determinant indicators organized within 4 domains at the individual, family, community and societal level. This indicator framework addresses a data gap identified in Canada’s strategy for mental health and will be used to inform programs and policies to improve the mental health status of Canadians throughout the life course.

    Socioeconomic status has been operationalised in a variety of ways, most commonly as education, social class, or income. In this study, we also use occupational complexity and a SES-index as alternative measures of socioeconomic status. Studies show that in analyses of health inequalities in the general population, the choice of indicators influence the magnitude of the observed inequalities. Less is known about the influence of indicator choice in studies of older adults. The aim of this study is twofold: i) to analyse the impact of the choice of socioeconomic status indicator on the observed health inequalities among older adults, ii) to explore whether different indicators of socioeconomic status are independently associated with health in old age. We combined data from two nationally representative Swedish surveys, providing more than 20 years of follow-up. Average marginal effects were estimated to compare the association between the five indicators of SES, and three late-life health outcomes: mobility limitations, limitations in activities of daily living (ADL), and psychological distress. All socioeconomic status indicators were associated with late-life health; there were only minor differences in the effect sizes. Income was most strongly associated to all indicators of late-life health, the associations remained statistically significant when adjusting for the other indicators. In the fully adjusted models, education contributed to the model fits with 0-3% (depending on the outcome), social class with 0-1%, occupational complexity with 1-8%, and income with 3-18%. Our results indicate overlapping properties between socioeconomic status indicators in relation to late-life health. However, income is associated to late-life health independently of all other variables. Moreover, income did not perform substantially worse than the composite SES-index in capturing health variation. Thus, if the primary objective of including an indicator of socioeconomic

    In Latin America and the Caribbean, with a population of approximately 580 million inhabitants, less than 20 % of wastewater is treated. Megacities in this region face common challenges and problems related with water quality and sanitation, which require urgent actions, such as changes in the sustainable use of water resources. The Mexico City Metropolitan Area is one of the most populous urban agglomerations in the world, with over 20 million inhabitants, and is no exception to the challenges of sustainable water management. For more than 100 years, wastewater from Mexico City has been transported north to the Mezquital Valley, which is ranked as the largest wastewater-irrigated area in the world. In this study, bacteria and pathogenic protozoa were analyzed to determine the association between the presence of such microorganisms and water types (WTs) across sampling sites and seasons in Mexico City and the Mezquital Valley. Our results show a difference in microbiological water quality between sampling sites and WTs. There is no significant interaction between sampling sites and seasons in terms of bacterial concentration, demonstrating that water quality remains constant at each site regardless of whether it is the dry or the rainy season. The results illustrate the quantity of these microorganisms in wastewater, provide a current diagnosis of water quality across the area which could affect the health of residents in both Mexico City and the Mezquital Valley, and demonstrate the need to transition in the short term to treat wastewater from a local to a regional scale.

    The Upper Floridan aquifer in the southern region of Florida is a multi-use, regional scale aquifer that is used as a potable water source and as a repository for passively recharged untreated surface waters, and injected treated surface water and wastewater, industrial wastes, including those which contain greenhouse gases (for example, carbon dioxide). The presence of confined zones within the Floridan aquifer that range in salinity from fresh to brackish allow regulatory agencies to permit the injection of these different types of product waters into specific zones without detrimental effects to humans and terrestrial and aquatic ecosystems. The type of recharge that has received the most regulatory attention in south Florida is aquifer storage and recovery (ASR). The treated water, prior to injection and during recovery, must meet primary and secondary drinking water standards. The primary microbiology drinking water standard is total coliforms, which have been shown to be difficult to inactivate below the regulatory standard during the treatment process at some ASR facilities. The inefficient inactivation of this group of indicator bacteria permits their direct injection into the storage zones of the Floridan aquifer. Prior to this study, the inactivation rates for any member of the total coliform group during exposure to native geochemical conditions in groundwater from any zone of the Floridan aquifer had not been derived. Aboveground flow through mesocosms and diffusion chambers were used to quantify the inactivation rates of two bacterial indicators, Escherichia coli and Pseudomonas aeruginosa, during exposure to groundwater from six wells. These wells collect water from two ASR storage zones: the Upper Floridan aquifer (UFA) and Avon Park Permeable Zone (APPZ). Both bacterial strains followed a biphasic inactivation model. The E. coli populations had slower inactivation rates in the UFA (range: 0.217–0.628 per hour (h-1)) during the first phase of the

    In many developing countries including Malawi, health indicators are on average better in urban than in rural areas. This phenomenon has largely prompted Governments to prioritize rural areas in programs to improve access to health services. However, considerable evidence has emerged that some population groups in urban areas may be facing worse health than rural areas and that the urban advantage may be waning in some contexts. We used a descriptive study undertaking a comparative analysis of 13 child health indicators between urban and rural areas using seven data points provided by nationally representative population based surveys-the Malawi Demographic and Health Surveys and Multiple Indicator Cluster Surveys. Rate differences between urban and rural values for selected child health indicators were calculated to denote whether urban-rural differentials showed a trend of declining urban advantage in Malawi. The results show that all forms of child mortality have significantly declined between 1992 and 2015/2016 reflecting successes in child health interventions. Rural-urban comparisons, using rate differences, largely indicate a picture of the narrowing gap between urban and rural areas albeit the extent and pattern vary among child health indicators. Of the 13 child health indicators, eight (neonatal mortality, infant mortality, under-five mortality rates, stunting rate, proportion of children treated for diarrhea and fever, proportion of children sleeping under insecticide-treated nets, and children fully immunized at 12 months) show clear patterns of a declining urban advantage particularly up to 2014. However, U-5MR shows reversal to a significant urban advantage in 2015/2016, and slight increases in urban advantage are noted for infant mortality rate, underweight, full childhood immunization, and stunting rate in 2015/2016. Our findings suggest the need to rethink the policy viewpoint of a disadvantaged rural and much better-off urban in child health

    To identify indicators of accuracy for consumer health information on the Internet. Several popular search engines were used to find websites on carpal tunnel syndrome. The accuracy and completeness of these sites were determined by orthopedic surgeons. It also was noted whether proposed indicators of accuracy were present. The correlation between proposed indicators of accuracy and the actual accuracy of the sites was calculated. A total of 116 websites and 29 candidate indicators were examined. A high Google toolbar rating of the main page of a site, many inlinks to the main page of a site, and an unbiased presentation of information on carpal tunnel syndrome were considered genuine indicators of accuracy. Many proposed indicators taken from published guidelines did not indicate accuracy (e.g., the author or sponsor having medical credentials). There are genuine indicators of the accuracy of health information on the Internet. Determining these indicators, and informing providers and consumers of health information about them, would be useful for public health care. Published guidelines have proposed many indicators that are obvious to unaided observation by the consumer. However, indicators that make use of the invisible link structure of the Internet are more reliable guides to accurate information on carpal tunnel syndrome.

  1. Recent advances in microbial fermentation for dairy and health [version 1; referees: 3 approved

    Full Text Available Microbial fermentation has been used historically for the preservation of foods, the health benefits of which have since come to light. Early dairy fermentations depended on the spontaneous activity of the indigenous microbiota of the milk. Modern fermentations rely on defined starter cultures with desirable characteristics to ensure consistency and commercial viability. The selection of defined starters depends on specific phenotypes that benefit the product by guaranteeing shelf life and ensuring safety, texture, and flavour. Lactic acid bacteria can produce a number of bioactive metabolites during fermentation, such as bacteriocins, biogenic amines, exopolysaccharides, and proteolytically released peptides, among others. Prebiotics are added to food fermentations to improve the performance of probiotics. It has also been found that prebiotics fermented in the gut can have benefits that go beyond helping probiotic growth. Studies are now looking at how the fermentation of prebiotics such as fructo-oligosaccharides can help in the prevention of diseases such as osteoporosis, obesity, and colorectal cancer. The potential to prevent or even treat disease through the fermentation of food is a medically and commercially attractive goal and is showing increasing promise. However, the stringent regulation of probiotics is beginning to detrimentally affect the field and limit their application.

    Association between deprivation and health is well established, particularly among unemployed or fixed-term contract or temporary contract subjects. This study aimed to assess if this relationship existed as well in full-time permanent workers. Biometrical, biological, behavioural and psychosocial health risk indicators and an individual deprivation score, the Evaluation of Precarity and Inequalities in Health Examination Centres score, were recorded from January 2007 to June 2008, in 34 905 full-time permanent workers aged 18-70 years, all volunteers for a free health examination. Comparisons of the behavioural, metabolic, cardiovascular and health risk indicators between quintiles of the deprivation score with adjustments on age and socioeconomic categories were made by covariance analysis or logistic regression. For both genders, degradation of nutritional behaviours, metabolic and cardiovascular indicators and health appeared gradually with deprivation, even for deprivation score usually considered as an insignificant value. The absence of only one social support or one social network was associated with a degradation of health. Full-time permanent workers with the poorest health risk indicators had more frequent social exclusion signs. These results were independent of socioeconomic categories and age. Understanding how deprivation influences health status may lead to more effective interventions to reduce social inequalities in health. The deprivation Evaluation of Precarity and Inequalities in Health Examination Centres score is a relevant tool to detect subjects who could benefit from preventive interventions. Our findings suggest that this deprivation score should be used as a health risk indicator even in full-time permanent workers. Assessing deprivation is useful to design and evaluate specific intervention programmes. © The Author 2013. Published by Oxford University Press on behalf of the European Public Health Association.

    When the Government of Ontario launched a comprehensive mental health and addictions strategy, the Institute for Clinical Evaluative Sciences (ICES) was tasked with developing a scorecard for ongoing monitoring of the child and youth mental health system. Using existing administrative and survey-based healthcare and education data, researchers at ICES developed a scorecard consisting of 25 indicators that described at-risk populations, child and youth mental healthcare and relevant outcomes. This scorecard is the first in Canada to report on performance indicators for the child and youth mental health system and provides a model for monitoring child and youth mental health using routinely collected administrative data.

    Full Text Available The health of the coral reefs of the Abrolhos Bank (Southwestern Atlantic was characterized with a holistic approach using measurements of four ecosystem components: (i inorganic and organic nutrient concentrations, [1] fish biomass, [1] macroalgal and coral cover and (iv microbial community composition and abundance. The possible benefits of protection from fishing were particularly evaluated by comparing sites with varying levels of protection. Two reefs within the well-enforced no-take area of the National Marine Park of Abrolhos (Parcel dos Abrolhos and California were compared with two unprotected coastal reefs (Sebastião Gomes and Pedra de Leste and one legally protected but poorly enforced coastal reef (the "paper park" of Timbebas Reef. The fish biomass was lower and the fleshy macroalgal cover was higher in the unprotected reefs compared with the protected areas. The unprotected and protected reefs had similar seawater chemistry. Lower vibrio CFU counts were observed in the fully protected area of California Reef. Metagenome analysis showed that the unprotected reefs had a higher abundance of archaeal and viral sequences and more bacterial pathogens, while the protected reefs had a higher abundance of genes related to photosynthesis. Similar to other reef systems in the world, there was evidence that reductions in the biomass of herbivorous fishes and the consequent increase in macroalgal cover in the Abrolhos Bank may be affecting microbial diversity and abundance. Through the integration of different types of ecological data, the present study showed that protection from fishing may lead to greater reef health. The data presented herein suggest that protected coral reefs have higher microbial diversity, with the most degraded reef (Sebastião Gomes showing a marked reduction in microbial species richness. It is concluded that ecological conditions in unprotected reefs may promote the growth and rapid evolution of opportunistic

    Full Text Available The World Health Organization emphasized the importance of mental health by including it in their definition of health as 'a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.' Mental health has direct influence to the quality of life of citizens as well as to productivity of economy. Therefore, both government and enterprises are interested for further improvement in this field. The European Health Consumer Index (EHCI was founded as a project in 2006, and it has been working ever since on comparison and ranking of the health systems of the European countries. Its main aim is the setting of standards for well-functioning and organization of health care from the perspective of patients (consumers - users of the health system. Assessment of the health system is based on pre-determined forty eight indicators, divided into six groups. The aim of this study was to assess the state of Serbian mental health care in 2014 and 2015 from the perspective of European health consumer index and propose recommendations for its improvement and functioning in accordance with the norms of European standards. The Republic of Serbia, according to the European Health Consumer Index, was ranked 33rd. in 2014 among European countries, with 473 points, while in 2015 was ranked 30 with 554 points. Mental health care indicators shows improvement in 2015 comparing with 2014. year.

    Quality-of-work-life (QWL) includes broad aspects of the work environment that affect employee learning and health. Canadian health care organizations (HCOs) are being encouraged to monitor QWL, expanding existing occupational health surveillance capacities. To investigate the understanding, collection, diffusion and use of QWL indicators in Canadian HCOs. We obtained cooperation from six diverse public HCOs managing 41 sites. We reviewed documentation relevant to QWL and conducted 58 focus groups/team interviews with strategic, support and programme teams. Group interviews were taped, reviewed and analysed for themes using qualitative data techniques. Indicators were classified by purpose and HCO level. QWL indicators, as such, were relatively new to most HCOs yet the data managed by human resource and occupational health and safety support teams were highly relevant to monitoring of employee well-being (119 of 209 mentioned indicators), e.g. sickness absence. Monitoring of working conditions (62/209) was also important, e.g. indicators of employee workload. Uncommon were indicators of biomechanical and psychosocial hazards at work, despite their being important causes of morbidity among HCO employees. Although imprecision in the definition of QWL indicators, limited links with other HCO performance measures and inadequate HCO resources for implementation were common, most HCOs cited ways in which QWL indicators had influenced planning and evaluation of prevention efforts. Increase in targeted HCO resources, inclusion of other QWL indicators and greater integration with HCO management systems could all improve HCO decision-makers' access to information relevant to employee health.

    This study aimed at developing a list of key human health indicators for quantifying the health impacts of climate change in Canada. A literature review was conducted in OVID Medline to identify health morbidity and mortality indicators currently used to quantify climate change impacts. Public health frameworks and other studies of climate change indicators were reviewed to identify criteria with which to evaluate the list of proposed key indicators and a rating scale was developed. Total scores for each indicator were calculated based on the rating scale. A total of 77 health indicators were identified from the literature. After evaluation using the chosen criteria, 8 indicators were identified as the best for use. They include excess daily all-cause mortality due to heat, premature deaths due to air pollution (ozone and particulate matter 2.5), preventable deaths from climate change, disability-adjusted life years lost from climate change, daily all-cause mortality, daily non-accidental mortality, West Nile Disease incidence, and Lyme borreliosis incidence. There is need for further data and research related to health effect quantification in the area of climate change.

    Full Text Available Objectives: Performance indicators are a popular mechanism for measuring the quality of healthcare to facilitate both quality improvement and systems management. Few studies make comparative assessments of different countries’ performance indicator frameworks. This study identifies and compares frameworks and performance indicators used in selected Organisation for Economic Co-operation and Development health systems to measure and report on the performance of healthcare organisations and local health systems. Countries involved are Australia, Canada, Denmark, England, the Netherlands, New Zealand, Scotland and the United States. Methods: Identification of comparable international indicators and analyses of their characteristics and of their broader national frameworks and contexts were undertaken. Two dimensions of indicators – that they are nationally consistent (used across the country rather than just regionally and locally relevant (measured and reported publicly at a local level, for example, a health service – were deemed important. Results: The most commonly used domains in performance frameworks were safety, effectiveness and access. The search found 401 indicators that fulfilled the ‘nationally consistent and locally relevant’ criteria. Of these, 45 indicators are reported in more than one country. Cardiovascular, surgery and mental health were the most frequently reported disease groups. Conclusion: These comparative data inform researchers and policymakers internationally when designing health performance frameworks and indicator sets.

    The aim of this study was to investigate how moderately increased dietary red meat combined with a soluble fiber (wheat arabinoxylan [AX]) alters the large intestinal microbiota in terms of fermentative end products and microbial community profiles in pigs. Four groups of 10 pigs were fed Western-type diets containing two amounts of red meat, with or without a solubilized wheat AX-rich fraction for 4 wk. After euthanasia, fermentative end products (short-chain fatty acids, ammonia) of digesta from four sections of large intestine were measured. Di-amino-pimelic acid was a measure of total microbial biomass, and bacterial profiles were determined using a phylogenetic microarray. A factorial model determined effects of AX and meat content. Arabinoxylan was highly fermentable in the cecum, as indicated by increased concentrations of short-chain fatty acids (particularly propionate). Protein fermentation end products were decreased, as indicated by the reduced ammonia and branched-chain ratio although this effect was less prominent distally. Microbial profiles in the distal large intestine differed in the presence of AX (including promotion of Faecalibacterium prausnitzii), consistent with an increase in carbohydrate versus protein fermentation. Increased di-amino-pimelic acid (P < 0.0001) suggested increased microbial biomass for animals fed AX. Solubilized wheat AX has the potential to counteract the effects of dietary red meat by reducing protein fermentation and its resultant toxic end products such as ammonia, as well as leading to a positive shift in fermentation end products and microbial profiles in the large intestine.

    Despite the expanding use of social media, little has been published about its appropriate role in health promotion, and even less has been written about evaluation. The purpose of this article is threefold: (a) outline purposes for social media in health promotion, (b) identify potential key performance indicators associated with these purposes, and (c) propose evaluation metrics for social media related to the key performance indicators. Process evaluation is presented in this article as an overarching evaluation strategy for social media.

    Ensuring the health and productivity of emergency medical services (EMS) professionals is important. However, there has been no known national baseline assessment of the health and wellness of EMS professionals in the United States. According to Healthy People 2010, top indicators of personal health include physical activity, body mass index (BMI), and smoking prevalence. The objectives of this study included quantifying existing health conditions and describing key health indicators among EMS professionals. It was hypothesized that work-life characteristics were associated with existing health conditions and key health indicators. Data utilized for this analysis were obtained from a 2007 questionnaire included in biennial national recertification packets. This questionnaire utilized validated items from the Behavioral Risk Factor Surveillance System (BRFSS) and the Longitudinal EMT Attributes and Demographics Study (LEADS). Along with common demographic characteristics, items inquired about existing health conditions (diabetes, asthma, hypertension, myocardial infarction, angina, stroke, and/or high blood cholesterol level), general health, physical activity, and smoking status. Descriptive analyses were performed utilizing chi-square tests, and logistic regression was utilized to describe associations between existing health conditions and the key health indicators. There were 58,435 individuals who became recertified in 2007, with 30,560 (52%) returning questionnaires. Individuals with missing data were removed, leaving 19,960 individual records. There were 4,681 (23.5%) individuals who reported at least one existing health condition. The mean BMI for the study participants was 27.69 kg/m(2). There were 5,742 (28.8%) individuals classified as having normal weight and 5,146 (25.8%) who were obese. The overwhelming majority of individuals did not meet the Centers for Disease Control and Prevention (CDC) recommendations for physical activity (15,022, 75.3%). There

    This article describes a pilot study evaluating the sensitivity of Indigenous community health to climate change impacts on Salish Sea shorelines (Washington State, United States and British Columbia, Canada). Current climate change assessments omit key community health concerns, which are vital to successful adaptation plans, particularly for Indigenous communities. Descriptive scaling techniques, employed in facilitated workshops with two Indigenous communities, tested the efficacy of ranking six key indicators of community health in relation to projected impacts to shellfish habitat and shoreline archaeological sites stemming from changes in the biophysical environment. Findings demonstrate that: when shellfish habitat and archaeological resources are impacted, so is Indigenous community health; not all community health indicators are equally impacted; and, the community health indicators of highest concern are not necessarily the same indicators most likely to be impacted. Based on the findings and feedback from community participants, exploratory trials were successful; Indigenous-specific health indicators may be useful to Indigenous communities who are assessing climate change sensitivities and creating adaptation plans.

    1999-12-01

    Two freshwater bathing sites, the Crook O'Lune and the University Boathouse, on the River Lune in the north-west of England, were monitored over a 2 year period for the faecal indicators, faecal coliforms and faecal streptococci, the pathogens, Salmonella and Campylobacter, and compliance with the EU Directive on Bathing Water Quality. Faecal indicator numbers showed no seasonal variation, with numbers in the bathing season similar to those in the non-bathing season. They were consistently above the EU Guideline and Imperative standards so that if the EU Bathing Water Quality Directive (76/160/EEC) were applied, neither site would comply. Faecal indicator numbers in the sediments were an order of magnitude higher than in the overlying water. Campylobacter numbers showed seasonal variation in the water with higher counts in winter than in the summer, although numbers were low. Higher numbers were found in the sediments but there was no seasonal variation. Analysis of various inputs showed that indicators and campylobacters came from a mixture of sources, namely a sewage treatment works, agricultural run-off, streams and mallards. Microbial numbers in the water at the Crook O'Lune, which is closer to the sources of pollution, were twice those at the Boathouse. In the sediments they were six to eight times higher. Faecal coliforms were all identified as Escherichia coli of which 80% were a single biotype. Faecal streptococci were all enterococci of which 55% were E. avium, 38% E. faecalis and 7% E. durans. Salmonella was not isolated from either the water column or the sediments. Campylobacters were mainly Camp. jejuni, followed by Camp. coli, UPTC and Camp. lari.

    Full Text Available Colistin (Polymyxin E is one of the few cationic antimicrobial peptides commercialized in both human and veterinary medicine. For several years now, colistin has been considered the last line of defense against infections caused by multidrug-resistant (MDR Gram-negative such as Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae. Colistin has been extensively used orally since the 1960s in food animals and particularly in swine for the control of Enterobacteriaceae infections. However, with the recent discovery of plasmid-mediated colistin resistance encoded by the mcr-1 gene and the higher prevalence of samples harboring this gene in animal isolates compared to other origins, livestock has been singled out as the principal reservoir for colistin resistance amplification and spread. Co-localization of the mcr-1 gene and Extended-Spectrum- β-lactamase (ESBL genes on a unique plasmid has been also identified in many isolates from animal origin. The use of colistin in pigs as a growth promoter and for prophylaxis purposes should be banned, and the implantation of sustainable measures in pig farms for microbial infection prevention should be actively encouraged and financed. The scientific research should be encouraged in swine medicine to generate data helping to reduce the exacerbation of colistin resistance in pigs and in manure. The establishment of guidelines ensuring a judicious therapeutic use of colistin in pigs, in countries where this drug is approved, is of crucial importance. The implementation of a microbiological withdrawal period that could reduce the potential contamination of consumers with colistin resistant bacteria of porcine origin should be encouraged.

  7. The 'sialo-microbial-dental complex' in oral health and disease.

    Science.gov (United States)

    Kaidonis, John; Townsend, Grant

    2016-01-01

    Biofilms are naturally found in all wet environments including the oral structures of nearly all species. Human oral biofilms have existed since our earliest ancestors and have evolved symbiotically with the dentition over many millennia within a Palaeolithic, hunter-gatherer setting. Irrespective of the plant-animal ratio, it can be argued that the Palaeolithic diet was essentially acidic, and acted as a selective force for much of the evolution of the stomatognathic system. The relationship between saliva, biofilm and teeth, the 'sialo-microbial-dental complex', provides oral health benefits and offers a different perspective to the old dental paradigm that only associated oral biofilms (plaque) with disease (caries). This new paradigm emphasises that oral biofilms are essential for the 'mineral maintenance' of teeth. Oral biofilms provide physical protection from dietary acid and together with bacterial metabolic acids cause the resting pH of the biofilm to fall below neutral. This is then followed by the re-establishment of a neutral environment by chemical interactions mediated by the saliva within the biofilm. Such pH fluctuations are often responsible for the cyclic demineralisation, then remineralisation of teeth, a process necessary for tooth maturation. However, since the advent of farming and especially since the industrial revolution, the increase in consumption of carbohydrates, refined sugars and acidic drinks has changed the ecology of biofilms. Biofilm biodiversity is significantly reduced together with a proliferation of acidogenic and aciduric organisms, tipping the balance of the 'demin-remin' cycle towards net mineral loss and hence caries. In addition, the consumption of acidic drinks in today's societies has removed the protective nature of the biofilm, leading to erosion. Erosion and caries are 'modern-day' diseases and reflect an imbalance within the oral biofilm resulting in the demineralisation of teeth. Copyright © 2015 The Authors

  8. A combined sensitivity analysis and kriging surrogate modeling for early validation of health indicators

    To increase the dependability of complex systems, one solution is to assess their state of health continuously through the monitoring of variables sensitive to potential degradation modes. When computed in an operating environment, these variables, known as health indicators, are subject to many uncertainties. Hence, the stochastic nature of health assessment combined with the lack of data in design stages makes it difficult to evaluate the efficiency of a health indicator before the system enters into service. This paper introduces a method for early validation of health indicators during the design stages of a system development process. This method uses physics-based modeling and uncertainties propagation to create simulated stochastic data. However, because of the large number of parameters defining the model and its computation duration, the necessary runtime for uncertainties propagation is prohibitive. Thus, kriging is used to obtain low computation time estimations of the model outputs. Moreover, sensitivity analysis techniques are performed upstream to determine the hierarchization of the model parameters and to reduce the dimension of the input space. The validation is based on three types of numerical key performance indicators corresponding to the detection, identification and prognostic processes. After having introduced and formalized the framework of uncertain systems modeling and the different performance metrics, the issues of sensitivity analysis and surrogate modeling are addressed. The method is subsequently applied to the validation of a set of health indicators for the monitoring of an aircraft engine’s pumping unit

    By 1979 50 years of uneven development and modernization by governments prior to the Islamic Revolution had left rural parts of the Islamic Republic of Iran with extremely low economic and health status. This paper reports on the impact of the rural health development programme implemented as an effective and inexpensive way to improve the heath of the rural population, especially mothers and children. It describes the system of rural health centres, health houses and community health workers (behvarz) and demonstrates the effectiveness of the programme through declining measures of rural-urban disparities in health indicators. The implications of inexpensive rural health policies for other countries in the region such as Afghanistan and Central Asian countries with a similar sociocultural structure are discussed.

    2009-01-01

    The Canadian Institute for Health Information (CIHI), in collaboration with diverse stakeholders, led the development of pan-Canadian indicators to measure primary health care. In 2006, CIHI released a set of 105 pan-Canadian Primary Health Care (PHC) indicators that were developed with the assistance of national, provincial and territorial representatives, clinicians and researchers. Additionally, data gaps were identified in a series of reports. In 2006 and 2007, CIHI assessed options for closing the data gaps so that the indicators could be measured and reported. CIHI then began a program to build the data infrastructure needed for the PHC indicators. The program included the development of content standards for electronic medical records, a prototype of a voluntary reporting system, enhancements to surveys, and the development of reports. In 2006, fewer than 10% of the 105 indicators could be calculated with existing data sources. Now, four projects have begun and over 50% of the indicators are being captured. Important relationships have been established with key collaborators. These relationships will lead to the development of a reporting system prototype and to the refinement of PHC indicators and electronic medical record (EMR) content standards. The project for pan-Canadian PHC indicators has encouraged consultation and synergy. It has motivated CIHI to establish an information program to fill data gaps and to make PHC indicators available.

    Full Text Available Purpose. The article is devoted to solving the problem of social measurement of modern youth’s health. The subject of the analysis is the content of the concept, characteristics and indicators of the social health of young people, which enable using sociological research’ methods to measure a given status of the younger generation in contemporary Russian society. The purpose of this work is to define the theoretical and methodological foundations of the sociological analysis of the young people social health and to substantiate its main indicators in the tools of complex sociological research. Methodology of the study. The basis of the research is formed by the system approach, the complex approach, the logical-conceptual method and general scientific methods of research: comparative analysis, system analysis, construction of social indicators, modeling. Results. The social health of young people is defined through the category “status” and is considered as an integrated indicator of the social quality of the younger generation. It is substantiated that the social health of youth is a status of socio-demographic community in which it is able not only to adapt to the changing conditions of the social environment but is also ready to transform actively the surrounding reality, having the potential to resist destructive social phenomena and processes. The main indicators that allow measuring the social health of young people by sociological methods are determined: adaptability in the social environment, social activity in all spheres of public life, social orientation and significance of activity, behavior regulativity by social norms and universal values, creativity of thinking and behavior, readiness for social integration and self-development. A system of social indicators and indicators for conducting a sociological study of social health in historical memory, value orientations and everyday practices of young people has been developed.

    Massively parallel sequencing has provided a more affordable and high-throughput method to study microbial communities, although it has mostly been used in an exploratory fashion. We combined pyrosequencing with a strict indicator species statistical analysis to test if bacteria specifically responded to ethanol injection that successfully promoted dissimilatory uranium(VI) reduction in the subsurface of a uranium contamination plume at the Oak Ridge Field Research Center in Tennessee. Remediation was achieved with a hydraulic flow control consisting of an inner loop, where ethanol was injected, and an outer loop for flow-field protection. This strategy reduced uranium concentrations in groundwater to levels below 0.126 μM and created geochemical gradients in electron donors from the inner-loop injection well toward the outer loop and downgradient flow path. Our analysis with 15 sediment samples from the entire test area found significant indicator species that showed a high degree of adaptation to the three different hydrochemical-created conditions. Castellaniella and Rhodanobacter characterized areas with low pH, heavy metals, and low bioactivity, while sulfate-, Fe(III)-, and U(VI)-reducing bacteria (Desulfovibrio, Anaeromyxobacter, and Desulfosporosinus) were indicators of areas where U(VI) reduction occurred. The abundance of these bacteria, as well as the Fe(III) and U(VI) reducer Geobacter, correlated with the hydraulic connectivity to the substrate injection site, suggesting that the selected populations were a direct response to electron donor addition by the groundwater flow path. A false-discovery-rate approach was implemented to discard false-positive results by chance, given the large amount of data compared. PMID:20729318

    The main function of vitamin D is calcium homeostasis. However, emerging evidence has correlated adequate serum 25-hydroxyvitamin D (25(OH)D) concentrations with better mental health. The objective of this study is to investigate the association of serum 25(OH)D concentrations with indicators of mental health such as depression, anxiety, and stress. Associations of serum 25(OH)D concentrations with four indicators of mental health were examined using ordered logistic regression models with increasing specificity that account for demographics, socio-economic status, and health. Margin effects are used to determine the probability of the average adult Canadian being in the best mental health state by groupings of serum 25(OH)D concentrations. A robust association between serum 25(OH)D concentrations and the indicators of mental health were observed. In the fully adjusted ordered logistic model, an average Canadian appeared more likely to experience better mental health when serum 25(OH)D concentrations were higher. This study adds to the weight of the existence of an association between vitamin D status and mental health, but, as this study is cross sectional, it does not establish causality. Due to the low risk of harm from toxicity and the relative modest costs of vitamin D supplements, more research to establish the effectiveness and causality of this relationship is recommended.

    A large number of migrants have move to cities in Thailand seeking employment. These people may be at increased risk for environmental health problems. We studied the health status, environmental living conditions and microbial indoor air quality (IAQ) among selected groups of migrant workers and their households in Mueang District, Samut Sakhon, central Thailand. We conducted a cross sectional study of 240 migrant workers and their households randomly selected by multistage sampling. The person responsible for hygiene at each studied household was interviewed using a structured questionnaire. Two indoor air samples were taken from each household (480 indoor air samples) to determine bacterial and fungal counts using a Millipore air tester; 240 outdoor air samples were collected for comparison. Ninety-nine point six percent of study subjects were Myanmar, 74.2% were aged 21-40 years, 91.7% had a primary school level education or lower and 53.7% had stayed in Thailand less than 5 years. Eight point three percent had a history of an underlying disease, 20.8% had a recent history of pulmonary tuberculosis in a family member within the previous year. Forty-three point eight percent had a current illness related to IAQ during a previous month. Twenty-one point three were current cigarette smokers, 15.0% were current alcohol consumers, and 5.0% exercises ≥3 times per week. Forty-nine point two percent never opened the windows of their bedrooms or living rooms for ventilation, 45% never cleaned their window screens, and 38.3% never put their pillows or mattresses in the sunlight. The mean(±SD) air bacterial count was 230(±229) CFU/m3 (outdoor air = 128±82 CFU/ m3), and the mean fungal count was 630(±842) CFU/m3 (outdoor air = 138±94 CFU/ m3). When the bacterial and fungal counts were compared with the guidelines of the American Conference of Governmental Industrial Hygienists, the bacterial counts in 6.5% of houses surveyed and the fungal counts in 28.8% of house

    Although many risk behaviors peak during young adulthood, little is known about health risk factors and access to care. This study assessed health indicators and health care access in a national sample of young adult veterans and civilians. Data were from the 2010 Behavioral Risk Factor Surveillance System, a national telephone survey. Of 27,471 participants, ages 19-30 years, 2.2% were veterans (74.6% were male) and 97.7% were civilians (37.6% were male). Gender-stratified comparisons assessed health indicators and health care access by veteran status. Multivariate logistic regression was used to examine health indicators and health care access as a function of gender and veteran status. In the overall sample, women were more likely than men to have insurance, to have a regular physician, and to have had a routine checkup and yet were more likely to report financial barriers to care. Women also were more likely than men to report general medical and mental distress and higher lifetime anxiety and depressive disorders, whereas men were more likely to be overweight or obese and to report tobacco use and high-risk drinking. Adjusted analyses revealed a higher likelihood of general medical distress and higher rates of lifetime anxiety disorders among veterans compared with civilians, although there were no differences between veterans and civilians regarding health care utilization and hazardous drinking. Findings extend the literature on health care status and modifiable risk factors for young adults by identifying differences between men and women and between veterans and civilians. Interventions may need to be tailored on the bases of gender and veteran status because of several differences in mental health and general health needs.

    To determine the minimal conditions (temperature-time), necessary to achieve set sanitation targets for selected microbial indicators during the continuous thermal treatment of pig slurry. The effectiveness of thermal treatment between 55 and 96°C was studied using Escherichia coli, enterococci, sulfite-reducing Clostridia (SRC), mesophilic culturable bacteria (MCB), F+-specific and somatic phages. Identification of SRC and MCB was performed using 16S rRNA gene analysis. Ten minutes at 70°C or 1 h at 60°C was sufficient to reduce the vegetative bacteria by 4-5 log(10), but it had little effect on somatic phages nor on spore formers, dominated by Clostridium sp. At 96°C, somatic phages were still detected, but there was a reduction of 3.1 log(10) for SRC and of 1.4 log(10) for MCB. At 96°C, Clostridium botulinum was identified among the thermotolerant MCB. Only those hygienic risks relating to mesophilic vegetative bacteria can be totally eliminated from pig slurry treated at 60°C (60 min) or 70°C (cost treatment using heat recovery). However, even at 96°C, certain pathogens may persist. Journal of Applied Microbiology © 2011 The Society for Applied Microbiology. No claim to French Government works.

    This study is a contribution towards a risk assessment of the São Domingos Mine area (Portugal), integrating information from: soil physicochemical characteristics, pseudo-total and bioavailable trace elements (As, Cd, Cr, Cu, Ni, Pb and Zn), ecotoxicological evaluation, and microbial indicators. The bioassays using soil eluates (seed germination, luminescent inhibition of Vibrio fischeri and Daphnia magna immobilization) confirmed the soil toxicity categorization obtained with the bioassays using soil (plant growth tests, Eisenia fetida mortality and avoidance behaviour). However, the soil identified as the most toxic using bioassays, was different from the expected when considering the results from pseudo-total and effective bioavailable trace elements. Taking in consideration the observations, it is highly recommended to complement the results from environmental chemistry with results from bioassays, in order to provide a more complete and relevant information on the bioavailability of contaminants and to characterize the risk of contaminated soils. - Highlights: ► Impaired soil retention and habitat functions for all tested soils. ► Aquatic and terrestrial bioassays agreed in the soil toxicity categorization. ► Do results obtained by chemical methods really translate into “biological availability”? ► In multi-contaminated sites, risk estimation based only on chemical methods is inadequate. ► Bioassays provide a more realistic risk assessment of contaminated sites. - Bioassays provide a more complete and relevant information to characterize the risk of contaminated soils, and should be used to complement chemical results.

Data envelopment analysis (DEA was used to evaluate the inefficiency of resource allocation and service utilization. Factor Analysis (FA was used to determine input/output indicators.The CI of Health Institutions, Beds in Health Institutions, Health Professionals and Outpatient Visits were -0.116, -0.012, 0.038, and 0.111, respectively. Gini coefficient for the 31 provinces varied between 0.05 and 0.43; out of these 23 (742% were observed to be technically efficient constituting the "best practice frontier". The other 8 (25.8% provinces were technically inefficient.Health professionals and outpatient services are focused on higher income levels, while the Health Institutions and Beds in Health Institutions were concentrated on lower income levels. In China, a few provinces attained a basic balance in both equity and efficiency in terms of current health resource and service utilization, thus serving as a reference standard for other provinces.

    Modern society faces serious challenges, among them, the complexity of environmental problems. Thus, there are several possible sources of environmental degradation, however, the waste produced by health services have an important peculiarity due to its toxic or pathogenic characteristics, since when managed improperly provide also health risk public. The involvement of solid waste from healthcare services environmental impact integrates matters a little more complex, because in addition to environmental health, they also interfere with the healthiness of environments that generate, with the consequences of nosocomial infections, occupational health and public. Thus, the management has become an urgent need, especially when we see no use of performance indicators management in healthcare environments in the city of São Mateus, ES. For this, we used the Analytic Hierarchy Process Method to prioritize such indicators as the potential improvement in health services waste management process - WHS and thus environmental analysis was performed with the use of a template for SWOT analysis.

    Content quality indicators are warranted in order to help patients and consumers to judge the content quality of health-related on-line information. The aim of the present study is to evaluate web-based information on health topics and to assess particular content quality indicators like HON (Health on the Net) and DISCERN. The present study is based on the analysis of data issued from six previous studies which assessed with a standardized tool the general and content quality (evidence-based health information) of health-related websites. Keywords related to Social phobia, bipolar disorders, pathological gambling as well as cannabis, alcohol and cocaine addiction were entered into popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability and content quality (evidence-based information). "Health on the Net" (HON) quality label, and DISCERN scale scores were used to verify their efficiency as quality indicators. Of 874 websites identified, 388 were included. Despite an observed association with higher content quality scores, the HON label fails to predict good content quality websites when used in a multiple regression. Sensibility and specificity of a DISCERN score >40 in the detection of good content quality websites were, respectively, 0.45 and 0.96. The DISCERN is a potential quality indicator with a relatively high specificity. Further developments in this domain are warranted in order to facilitate the identification of high-quality information on the web by patients.

    Various behaviors are considered health enhancing. Nevertheless, according to the current scientific literature, four health behaviors are considered particularly risky in view of their association with a group of chronic diseases: 1) smoking; 2) excessive alcohol consumption; 3) poor diet; and 4) lack of physical activity. Theoretically, it should be possible to make improvements to one's health by maximizing the number of healthy behaviors and minimizing the unhealthy ones. However, in reality, the different behaviors interconnect to create more complex lifestyles. Therefore, the objective of this paper is to present the construction of a lifestyle indicator based on health behaviors selected in the ELSA-Brazil study. This indicator revealed two lifestyles: less healthy and healthier lifestyles. The model proved adequate and was confirmed using latent class analysis (LCA). Agreement was 83.2 between the indicator and the LCA results, with a kappa coefficient of 0.65. Women were more likely to have a healthier lifestyle than men, reinforcing the scientific consistency of the indicator, since this finding is in agreement with data from the scientific literature. The indicator created to define lifestyle was found to have scientific consistency and validity; therefore, its use can be recommended for future population-based studies concerning the promotion of health and healthy lifestyles.

    Urban health indicator (UHI) tools provide evidence about the health impacts of the physical urban environment which can be used in built environment policy and decision-making. Where UHI tools provide data at the neighborhood (and lower) scale they can provide valuable information about health inequalities and environmental deprivation. This review performs a census of UHI tools and explores their nature and characteristics (including how they represent, simplify or address complex systems) to increase understanding of their potential use by municipal built environment policy and decision-makers. We searched seven bibliographic databases, four key journals and six practitioner websites and conducted Google searches between January 27, 2016 and February 24, 2016 for UHI tools. We extracted data from primary studies and online indicator systems. We included 198 documents which identified 145 UHI tools comprising 8006 indicators, from which we developed a taxonomy. Our taxonomy classifies the significant diversity of UHI tools with respect to topic, spatial scale, format, scope and purpose. The proportions of UHI tools which measure data at the neighborhood and lower scale, and present data via interactive maps, have both increased over time. This is particularly relevant to built environment policy and decision-makers, reflects growing analytical capability and offers the potential for improved understanding of the complexity of influences on urban health (an aspect noted as a particular challenge by some indicator producers). The relation between urban health indicators and health impacts attributable to modifiable environmental characteristics is often indirect. Furthermore, the use of UHI tools in policy and decision-making appears to be limited, thus raising questions about the continued development of such tools by multiple organisations duplicating scarce resources. Further research is needed to understand the requirements of built environment policy and

    The Adélie Basin, located offshore of the Wilkes Land margin, experiences unusually high sedimentation rates (~ 2 cm yr− 1) for the Antarctic coast. This study sought to compare depthwise changes in organic matter (OM) quantity and quality with changes in microbial biomass with depth at this high-deposition site and an offshore continental margin site. Sediments from both sites were collected during the International Ocean Drilling (IODP) Program Expedition 318. Viable microbial biomass was estimated from concentrations of bacterial-derived phospholipid fatty acids, while OM quality was assessed using four different amino acid degradation proxies. Concentrations of total hydrolysable amino acids (THAA) measured from the continental margin suggest an oligotrophic environment, with THAA concentrations representing only 2% of total organic carbon with relative proportions of non-protein amino acids β-alanine and γ-aminobutyric acid as high as 40%. In contrast, THAA concentrations from the near-shore Adélie Basin represent 40%–60% of total organic carbon. Concentrations of β-alanine and γ-aminobutyric acid were often below the detection limit and suggest that the OM of the basin as labile. DI values in surface sediments at the Adélie and margin sites were measured to be + 0.78 and − 0.76, reflecting labile and more recalcitrant OM, respectively. Greater DI values in deeper and more anoxic portions of both cores correlated positively with increased relative concentrations of phenylalanine plus tyrosine and may represent a change of redox conditions, rather than OM quality. This suggests that DI values calculated along chemical profiles should be interpreted with caution. THAA concentrations, the percentage of organic carbon (CAA%) and total nitrogen (NAA%) represented by amino acids at both sites demonstrated a significant positive correlation with bacterial abundance estimates. These data suggest that the selective degradation of amino acids, as

    The distribution of income related health inequalities appears to exhibit changing patterns when both developing countries and developed countries are examined. This paper tests for the existence of a health Kuznets' curve; that is, an inverse U-shape pattern between economic developments (as measured by GDP per capita) and income-related health inequalities (as measured by concentration indices). We draw upon both cross sectional (the World Health Survey) and a long longitudinal (the European Community Household Panel survey) dataset. Our results suggest evidence of a health Kuznets' curve on per capita income. We find a polynomial association where inequalities decline when GDP per capita reaches a magnitude ranging between $26,000 and $38,700. That is, income-related health inequalities rise with GDP per capita, but tail off once a threshold level of economic development has been attained.

    Outcome measures are being widely used by health services to assess the quality of health care. It is important to have a battery of useful performance indicators with high validity and feasibility. Thus, the objective of this study is to perform a review of reviews in order to identify outcome indicators for use in Primary Care. A review of systematic reviews (umbrella review) was carried out. The following databases were consulted: MedLine, EMBASE, and CINAHL, using descriptors and free terms, limiting searches to documents published in English or Spanish. In addition, a search was made for free terms in different web pages. Those reviews that offered indicators that could be used in the Primary Care environment were included. This review included a total of 5 reviews on performance indicators in Primary Care, which consisted of indicators in the following areas or clinical care processes: in osteoarthritis, chronicity, childhood asthma, clinical effectiveness, and prescription safety indicators. A total of 69 performance indicators were identified, with the percentage of performance indicators ranging from 0% to 92.8%. None of the reviews identified performed an analysis of the measurement control (feasibility or sensitivity to change of indicators). This paper offers a set of 69 performance indicators that have been identified and subsequently validated and prioritised by a panel of experts. Copyright © 2017 SECA.

    To evaluate the association between the proportion of tooth extractions, socioeconomic indicators, and the availability of oral health services in an underprivileged area of Brazil. An ecological study was carried out in 52 municipalities in the state of Minas Gerais, Brazil. The socioeconomic indicators employed were criteria for health care resources allocation, municipal human development index, Theil index, Gini coefficient, and sanitation conditions. Concerning the availability of oral health services, the following were considered: number of inhabitants, number of dental surgeons living in the city, number of dentists working in the public services, and number of municipal oral health care teams. The utilization of oral health services was evaluated using the indicators recommended by the Health Ministry's Basic Care Package (Pacto da Atencão Básica in Portuguese) and the number of procedures carried out in the primary care setting. The 17 variables assessed were grouped into factorial components, which were then analyzed in terms of their relationship with the dependent variable, tooth extractions. The following six components explained 73.5% of the overall variance: socioeconomic conditions, social inequality, Basic Care Package indicators, number of procedures carried out, ratio of dentists to inhabitants, and coverage of the Family Health Strategy. Inequalities in income distribution (P = 0.031) and coverage by the Family Health Strategy (P = 0.015) contributed significantly to explain the difference in the proportion of tooth extractions in the different municipalities under study. The dental loss observed in the region is largely explained by socioeconomic factors and aspects related to the organization of oral health services.

    Climate-related health indicators are potentially useful for tracking and predicting the adverse public health effects of climate change, identifying vulnerable populations, and monitoring interventions. However, there is a need to understand stakeholders' perspectives on the identification, development, and utility of such indicators. A qualitative approach was used, comprising semi-structured interviews with key informants and service providers from government and non-government stakeholder organizations in South Australia. Stakeholders saw a need for indicators that could enable the monitoring of health impacts and time trends, vulnerability to climate change, and those which could also be used as communication tools. Four key criteria for utility were identified, namely robust and credible indicators, specificity, data availability, and being able to be spatially represented. The variability of risk factors in different regions, lack of resources, and data and methodological issues were identified as the main barriers to indicator development. This study demonstrates a high level of stakeholder awareness of the health impacts of climate change, and the need for indicators that can inform policy makers regarding interventions.

    Contextual factors can influence health through exposures to health-promoting and risk-inducing factors. The aim of this study was to (1) build, from geotagged Twitter and Yelp data, a national food environment database and (2) to test associations between state food environment indicators and health outcomes. This is a cross-sectional study based upon secondary analyses of publicly available data. Using Twitter's Streaming Application Programming Interface (API), we collected and processed 4,041,521 food-related, geotagged tweets between April 2015 and March 2016. Using Yelp's Search API, we collected data on 505,554 unique food-related businesses. In linear regression models, we examined associations between food environment characteristics and state-level health outcomes, controlling for state-level differences in age, percent non-Hispanic white, and median household income. A one standard deviation increase in caloric density of food tweets was related to higher all-cause mortality (+46.50 per 100,000), diabetes (+0.75%), obesity (+1.78%), high cholesterol (+1.40%), and fair/poor self-rated health (2.01%). More burger Yelp listings were related to higher prevalence of diabetes (+0.55%), obesity (1.35%), and fair/poor self-rated health (1.12%). More alcohol tweets and Yelp bars and pub listings were related to higher state-level binge drinking and heavy drinking, but lower mortality and lower percent reporting fair/poor self-rated health. Supplemental analyses with county-level social media indicators and county health outcomes resulted in finding similar but slightly attenuated associations compared to those found at the state level. Social media can be utilized to create indicators of the food environment that are associated with area-level mortality, health behaviors, and chronic conditions.

    2013-01-01

    The goal of this study is to develop an emission based indicator for the health impact of the air pollution caused by traffic. This indicator must make it possible to compare different situations, for example different Urban Travel Plans, or technical innovations. Our work is based on a literature survey of methods for evaluating health impacts and, more particularly, those which relate to the atmospheric pollution caused by transport. We then define a health impact indicator based on the traffic emissions, named IISCEP for Chronic health impact indicator of pollutant emission. Here health is understood in a restricted meaning, excluding well-being. Only primary pollutants can be considered, as the inputs are emission data and an indicator must be simple. The indicator is calculated as the sum of each pollutant emission multiplied by a dispersion and exposition factor and a substance specific toxicity factor taking account of the severity. Last, two examples are shown using the IISCEP: comparison between petrol and diesel vehicles, and Nantes urban district in 2008 vs 2002. Even if it could still be improved, IISCEP is a straightforward indicator which can be used to gauge the chronic effects of inhaling primary pollutants. It can only be used in comparisons, between different scenarios or different technologies. The quality of the emissions data and the choice of the pollutants that are considered are the two essential factors that determine its validity and reliability. - Highlights: ► The goal of the study is to develop an emission based indicator for the health impact of the air pollution caused by traffic. ► It is based on a literature survey of methods for evaluating health impacts related to the atmospheric pollution. ► We define a composite indicator based on the traffic emissions and on local data as dispersion conditions and population. ► The indicator is a combination of pollutant emission, dispersion, exposition factor, and substance specific

    Full Text Available Abstract Background Oral health impairment comprises three conceptual domains; pain, appearance and function. This study sought to: (1 estimate the prevalence of severe oral health impairment as assessed by a summary oral health impairment measure, including aspects of dental pain, dissatisfaction with dental appearance and difficulty eating, among a birth cohort of Indigenous Australian young adults (n = 442, age range 16-20 years; (2 compare prevalence according to demographic, socio-economic, behavioural, dental service utilisation and oral health outcome risk indicators; and (3 ascertain the independent contribution of those risk indicators to severe oral health impairment in this population. Methods Data were from the Aboriginal Birth Cohort (ABC study, a prospective longitudinal investigation of Aboriginal individuals born 1987-1990 at an Australian regional hospital. Data for this analysis pertained to Wave-3 of the study only. Severe oral health impairment was defined as reported experience of toothache, poor dental appearance and food avoidance in the last 12 months. Logistic regression models were used to evaluate effects of demographic, socio-economic, behavioural, dental service utilisation and clinical oral disease indicators on severe oral health impairment. Effects were quantified as odds ratios (OR. Results The percent of participants with severe oral health impairment was 16.3 (95% CI 12.9-19.7. In the multivariate model, severe oral health impairment was associated with untreated dental decay (OR 4.0, 95% CI 1.6-9.6. In addition to that clinical indicator, greater odds of severe oral health impairment were associated with being female (OR 2.0, 95% CI 1.2-3.6, being aged 19-20 years (OR 2.1, 95% CI 1.2-3.6, soft drink consumption every day or a few days a week (OR 2.6, 95% 1.2-5.6 and non-ownership of a toothbrush (OR 1.9, 95% CI 1.1-3.4.

    According to the framework of "Pressure-State-Response", this study established an indicator system which can reflect comprehensive risk of environment and health for an area at large scale. This indicator system includes 17 specific indicators covering social and economic development, pollution emission intensity, air pollution exposure, population vulnerability, living standards, medical and public health, culture and education. A corresponding weight was given to each indicator through Analytical Hierarchy Process (AHP) method. Comprehensive risk assessment of the environment and health of 58 counties was conducted in the Jiangsu province, China, and the assessment result was divided into four types according to risk level. Higher-risk counties are all located in the economically developed southern region of Jiangsu province and relatively high-risk counties are located along the Yangtze River and Xuzhou County and its surrounding areas. The spatial distribution of relatively low-risk counties is dispersive, and lower-risk counties mainly located in the middle region where the economy is somewhat weaker in the province. The assessment results provide reasonable and scientific basis for Jiangsu province Government in formulating environment and health policy. Moreover, it also provides a method reference for the comprehensive risk assessment of environment and health within a large area (provinces, regions and countries).

    Health information technology dashboards that integrate evidence-based quality indicators can efficiently and accurately display patient risk information to promote early intervention and improve overall quality of patient care. We describe the process of developing, evaluating, and implementing a dashboard designed to promote quality care through display of evidence-based quality indicators within an electronic health record. Clinician feedback was sought throughout the process. Usability evaluations were provided by three nurse pairs and one physician from medical-surgical areas. Task completion times, error rates, and ratings of system usability were collected to compare the use of quality indicators displayed on the dashboard to the indicators displayed in a conventional electronic health record across eight experimental scenarios. Participants rated the dashboard as "highly usable" following System Usability Scale (mean, 87.5 [SD, 9.6]) and Poststudy System Usability Questionnaire (mean, 1.7 [SD, 0.5]) criteria. Use of the dashboard led to reduced task completion times and error rates in comparison to the conventional electronic health record for quality indicator-related tasks. Clinician responses to the dashboard display capabilities were positive, and a multifaceted implementation plan has been used. Results suggest application of the dashboard in the care environment may lead to improved patient care.

    Identifying a minimum set of efficiency indicators calculated from current information sources. Interventions adopted from the analysis of these indicators could contribute to health services sustainability. We applied the discussion group technique. A total of 23 quality coordinators from around the country and the representatives of the regional quality societies in SECA (Spanish Society for Quality in Healthcare) participated. Ten efficiency indicators useful for integrated management areas were identified and accepted, 5 in the area of primary care and 5 for hospital management. The efficiency indicators agreed upon could contribute to the sustainability of the health system without this affecting the quality of care. Copyright © 2014 SECA. Published by Elsevier Espana.

    Within the frame of the EU-funded MARLON project, background data were reviewed to explore the possibility of measuring health indicators during post-market monitoring for potential effects of feeds, particularly genetically modified (GM) feeds, on livestock animal health, if applicable. Four case studies (CSs) of potential health effects on livestock were framed and the current knowledge of a possible effect of GM feed was reviewed. Concerning allergenicity (CS-1), there are no case-reports of allergic reactions or immunotoxic effects resulting from GM feed consumption as compared with non-GM feed. The likelihood of horizontal gene transfer (HGT; CS-2) of GMO-related DNA to different species is not different from that for other DNA and is unlikely to raise health concerns. Concerning mycotoxins (CS-3), insect-resistant GM maize may reduce fumonisins contamination as a health benefit, yet other Fusarium toxins and aflatoxins show inconclusive results. For nutritionally altered crops (CS-4), the genetic modifications applied lead to compositional changes which require special considerations of their nutritional impacts. No health indicators were thus identified except for possible beneficial impacts of reduced mycotoxins and nutritional enhancement. More generally, veterinary health data should ideally be linked with animal exposure information so as to be able to establish cause-effect relationships. Copyright © 2017 Elsevier Ltd.

    The human gut microbiota is engaged in multiple interactions affecting host health during the host's entire life span. Microbes colonize the neonatal gut immediately following birth. The establishment and interactive development of this early gut microbiota are believed to be (at least partially) driven and modulated by specific compounds present in human milk. It has been shown that certain genomes of infant gut commensals, in particular those of bifidobacterial species, are genetically adapted to utilize specific glycans of this human secretory fluid, thus representing a very intriguing example of host-microbe coevolution, where both partners are believed to benefit. In recent years, various metagenomic studies have tried to dissect the composition and functionality of the infant gut microbiome and to explore the distribution across the different ecological niches of the infant gut biogeography of the corresponding microbial consortia, including those corresponding to bacteria and viruses, in healthy and ill subjects. Such analyses have linked certain features of the microbiota/microbiome, such as reduced diversity or aberrant composition, to intestinal illnesses in infants or disease states that are manifested at later stages of life, including asthma, inflammatory bowel disease, and metabolic disorders. Thus, a growing number of studies have reported on how the early human gut microbiota composition/development may affect risk factors related to adult health conditions. This concept has fueled the development of strategies to shape the infant microbiota composition based on various functional food products. In this review, we describe the infant microbiota, the mechanisms that drive its establishment and composition, and how microbial consortia may be molded by natural or artificial interventions. Finally, we discuss the relevance of key microbial players of the infant gut microbiota, in particular bifidobacteria, with respect to their role in health and

    The need to balance resources between community and hospital-based mental health services in the post-deinstitutionalisation era has been well-documented. However, few indicators have been developed to monitor the relationship between community and hospital services, in either developed or developing countries. There is a particular need for such indicators in the South African context, with its history of inequitable services based in custodial institutions under apartheid, and a new policy that proposes the development of more equitable community-based care. Indicators are needed to measure the distribution of resources and the relative utilisation of community and hospital-based services during the reform process. These indicators are potentially useful for assessing the implementation of policy objectives over time. To develop and document community/hospital indicators in public sector mental health services in South Africa. A questionnaire was distributed to provincial mental health coordinators requesting numbers of full-time equivalent (FTE) staff who provide mental health care at all service levels, annual patient admissions to hospitals and annual patient attendances at ambulatory care facilities. The information was supplemented by consultations with mental health coordinators in each of the 9 provinces. Population data were obtained from preliminary findings of the 1996 census. The community/hospital indicator measuring staff distribution was defined as the ratio of staff employed in community settings to all staff, expressed as a percentage. The community/hospital indicator measuring patient service utilisation was defined as the ratio of the annual ambulatory care attendance rate per 100,000 population to the sum of this rate and the annual hospital admission rate per 100,000 population, expressed as a percentage. Of psychiatric public sector staff, 25% are located in community settings in South Africa (provincial range: 11-70%). If hospital outpatient

    Full Text Available Introduction: Few studies have considered the factors independently associated with chronic fatigue syndrome (CFS and/or fibromyalgia (FM or considered the impact of these conditions on health status using population-based data. Methods: We used data from the nationally representative 2010 Canadian Community Health Survey (n= 59 101 to describe self-reported health professional-diagnosed CFS and/or FM, and their associations with 6 health status indicators. Results: In 2010, diagnosed CFS and FM are reported by 1.4% (95% confidence interval [CI]: 1.3%–1.6% and 1.5% (1.4%–1.7%, respectively, of the Canadian household population aged 12 years and over, with comorbid CFS and FM affecting 0.3% (0.3%–0.4% of that population. Prevalent CFS and/or FM were more common among women, adults aged 40 years and over, those with lowest income, and those with certain risk factors for chronic disease (i.e. obesity, physical inactivity and smoking. After controlling for differences between the groups, people with CFS and/or FM reported poorer health status than those with neither condition on 5 indicators of health status, but not on the measure of fair/poor mental health. Having both CFS and FM and having multiple comorbid conditions was associated with poorer health status. Conclusion: Co-occurrence of CFS and FM and having other chronic conditions were strongly related to poorer health status and accounted for much of the differences in health status. Understanding factors contributing to improved quality of life in people with CFS and/or FM, particularly in those with both conditions and other comorbidities, may be an important area for future research.

    Health system integration is a key component of health system reform with the goal of improving outcomes for patients, providers, and the health system. Although health systems continue to strive for better integration, current delivery of health services continues to be fragmented. A key gap in the literature is the lack of information on what successful integration looks like and how to measure achievement towards an integrated system. This multi-site study protocol builds on a prior knowledge synthesis completed by two of the primary investigators which identified 10 key principles that collectively support health system integration. The aim is to answer two research questions: What are appropriate indicators for each of the 10 key integration principles developed in our previous knowledge synthesis and what measurement tools are used to measure these indicators? To enhance generalizability of the findings, a partnership between Canada and Brazil was created as health system integration is a priority in both countries and they share similar contexts. This knowledge synthesis will follow an iterative scoping review process with emerging information from knowledge-user engagement leading to the refinement of research questions and study selection. This paper describes the methods for each phase of the study. Research questions were developed with stakeholder input. Indicator identification and prioritization will utilize a modified Delphi method and patient/user focus groups. Based on priority indicators, a search of the literature will be completed and studies screened for inclusion. Quality appraisal of relevant studies will be completed prior to data extraction. Results will be used to develop recommendations and key messages to be presented through integrated and end-of-grant knowledge translation strategies with researchers and knowledge-users from the three jurisdictions. This project will directly benefit policy and decision-makers by providing an easy

    Full Text Available The aim of this work is to evaluate the impact of high-power pulsed light (HPPL on the microbial control and nutritional properties of strawberries. Berries were treated with HPPL and afterwards analyzed in terms of microbial contamination, shelf life extension, antioxidant capacity, firmness, total phenolic, total anthocyanin and ascorbic acid content, and colour. Results indicate that the decontamination of strawberries by HPPL was significant compared to control. Naturally distributed mesophilic bacteria on the surface of strawberries were inactivated by 2.2 log, and inoculated Bacillus cereus and Listeria monocytogenes were inactivated by 1.5 and 1.1 log, respectively. Yeasts/microfungi distributed on the surface of strawberries were inactivated by 1 log. The shelf life of treated strawberries was extended by 2 days. The increase of temperature on the surface of fruit never exceeded 42 °C. No significantly important differences were observed in total phenolic, total anthocyanin and ascorbic acid content, and antioxidant capacity of strawberry fruits before and after pulsed light treatment. Moreover, no impact on the strawberry colour or firmness was found after HPPL treatment. In conclusion, HPPL is fast, effective, non-thermal and environmentally friendly technique which can be applied for microbial control of strawberries.

    despite goals for gender equity in South Asia, the relationship between gender-sensitive policies and the empowerment of women is complex and requires an analysis of how policies align with a broad set of social, cultural, political, and economic indicators that relate to women's health. through a review of four documents under the umbrella of the World Health Organization and the United Nations, a list of 17 gender-sensitive policy and 17 general health indicators was generated with a focus on health, education, economic, and political empowerment and violence against women. A series of policy documents and international and national databases that are accessible in the public domain were the major tools used to find supporting documentation to address women's health outcomes in Bangladesh, India, Nepal, Pakistan, and Sri Lanka. all five South Asian countries had several gender-sensitive policies that were measurable by indicators that contribute to health. Examination of political and economic status, birth sex ratios, human trafficking, illiteracy rates, maternal mortality rates, contraception prevalence, fertility rates, knowledge of HIV/AIDS prevention, access to skilled birth attendants, and microfinance show that large gender inequities still prevail despite the presence of gender-sensitive policies. in many cases, the presence of gender-sensitive policies did not reflect the realization of gender equity over a wide range of indicators. Although the economic, political, social, and cultural climates of the five countries may differ, the integration of women's needs into the formulation, implementation, and monitoring of policies is a universal necessity to achieve positive outcomes. 2011 Jacobs Institute of Women's Health.

    In Ontario, Canada, approximately $2.5 billion is spent yearly on occupational injuries in the healthcare sector. The healthcare sector has been ranked second highest for lost-time injury rates among 16 Ontario sectors since 2009 with female healthcare workers ranked the highest among all occupations for lost-time claims. There is a great deal of focus in Ontario's occupational health and safety system on compliance and fines, however despite this increased focus, the injury statistics are not significantly improving. One of the keys to changing this trend is the development of a culture of healthy and safe workplaces including the effective utilization of leading indicators within Occupational Health and Safety Management Systems (OHSMSs). In contrast to lagging indicators, which focus on outcomes retrospectively, a leading indicator is associated with proactive activities and consists of selected OHSMSs program elements. Using leading indicators to measure health and safety has been common practice in high-risk industries; however, this shift has not occurred in healthcare. The aim of this project is to conduct a longitudinal study implementing six elements of the Ontario Safety Association for Community and Healthcare (OSACH) system identified as leading indicators and evaluating the effectiveness of this intervention on improving selected health and safety workplace indicators. A quasi-experimental longitudinal research design will be used within two Ontario acute care hospitals. The first phase of the study will focus on assessing current OHSMSs using the leading indicators, determining potential facilitators and barriers to changing current OHSMSs, and identifying the leading indicators that could be added or changed to the existing OHSMS in place. Phase I will conclude with the development of an intervention designed to support optimizing current OHSMSs in participating hospitals based on identified gaps. Phase II will pilot test and evaluate the tailored

    We systematically reviewed PubMed and EBSCO business, looking for cost indicators of electronic health record (EHR) implementations and their associated benefit indicators. We provide a set of the most common cost and benefit (CB) indicators used in the EHR literature, as well as an overall estimate of the CB related to EHR implementation. Overall, CB evaluation of EHR implementation showed a rapid capital-recovering process. On average, the annual benefits were 76.5% of the first-year costs and 308.6% of the annual costs. However, the initial investments were not recovered in a few studied implementations. Distinctions in reporting fixed and variable costs are suggested.

    The objective of this study was to investigate if and how cow factors and intramammary infection (IMI) are associated with 4 different udder-health indicators in dairy cows as a first step in investigating whether the diagnostic performance of these indicators can be improved. The investigated indicators were somatic cell count (SCC), lactate dehydrogenase (LDH), N-acetyl-β-d-glucosaminidase (NAGase), and alkaline phosphatase (AP) measured in milk. In this cross-sectional study, approximately 1,000 cows from 25 dairy herds were sampled for bacteriology (quarter milk samples) during 3 consecutive days: the day before test milking, at the day of test milking, and at the day after test milking. The whole-udder test milking sample was analyzed for milk composition, SCC, LDH, NAGase, and AP. Cow data (parity, breed, milk yield, percentage of milk fat and protein, milk urea concentration, and days in milk from the sampled test milking) were collected from the Swedish milk-recording scheme. Of the sampled cows 485 were considered IMI negative and were used in multivariable mixed-effect linear regression models to investigate associations between cow factors and the udder-health indicators. A second modeling including all cows, both IMI negative and IMI positive (256 cows), was also performed. The results showed that all udder-health indicators were affected by cow factors but that different cow factors were associated with different indicators. Intramammary-infection status was significantly associated with all udder-health indicators except AP. Parity and milk urea concentration were the only cow factors associated with all indicators in all models. The significant cow factors explained 23% of the variation in SCC and >30% of the variation in LDH, NAGase, and AP in IMI-negative cows, showing that LDH, NAGase, and AP are more affected than SCC by cow factors. The IMI status explained 23% of the variation in SCC in the model with all cows but only 7% of the variation in

    Evidence suggests sitting time is independently associated with a range of health issues in adults, yet the relationship between sedentary behavior and health indicators in young people is less clear. Age-related increases in sedentary behavior are well-documented; the behavioral patterns of adolescent girls are of particular concern. More than one third of adolescent girls' sedentary behavior time is accumulated through use of recreational screen-based behaviors. The objective of this review was to investigate the association between recreational screen-based sedentary behavior and the physical, behavioral, and psychosocial health indicators for adolescent girls. A secondary objective was to identify studies that have adjusted sedentary behavior indicators for physical activity. A structured electronic search of all publication years (through December 2011) was conducted to identify studies in: CINAHL, Communications and Mass Media Complete, ERIC, MEDLINE with Full Text, PsycINFO, and SPORTDiscus with Full Text. Included publications were observational and interventional studies involving adolescent girls (12-18 years) that examined associations between screen-based, sedentary behavior and health indicators (physical, psychosocial, and/or behavioral). The search identified 33 studies that evaluated health indicators of screen-based sedentary behaviors among adolescent girls. Strong evidence for a positive association between screen-based sedentary behavior and weight status was found. A positive association was observed between screen-time and sleep problems, musculoskeletal pain and depression. Negative associations were identified between screen time and physical activity/fitness, screen time and psychological well-being, and screen time and social support. The relationship between screen-based sedentary behavior and diet quality was inconclusive. Less than half of the studies adjusted sedentary behavior indicators for physical activity.

    The overall purpose of the study was to examine if individuals with low motor competence achieve age-adequate fitness and health. A group of 149 children, adolescents, and adults with low or high motor competence participated in motor, fitness, and health assessments. Individuals with low motor competence did not differ on their basic physiological health parameters, but they had less optimal levels of overall health and fitness indices than those with high motor competence. As a function of age, musculoskeletal fitness was significantly compromised for the low motor competence group. The metabolic indices suggested that the low motor competence group had significantly higher BMI's compared to the high motor competence group. Motor skills and static balance were significant predictors of the BMI. Exercise intensity differed between children in the low and high motor competence group. The findings suggest that individuals with low motor competence have compromised health-related fitness. In order to discriminate between individuals with high and low motor competence, fitness assessment should include at least back extension, curl ups, and sit and reach. In addition, health-related fitness measurements such as BMI, waist circumference, blood lipid profile and bone mineral density are also recommended.

    The coastal ecosystem of Karimunjawa National Marine Park (KNMP) is facing various pressures, including from human activity. Monitoring the health condition of coastal ecosystems periodically is needed as an evaluation of the ecosystem condition. Systematic and consistent indicators are needed in monitoring of coastal ecosystem health. This paper presents hierarchical synthesis of coastal ecosystem health indicators using Analytic Hierarchy Process (AHP) method. Hierarchical synthesis is obtained from process of weighting by paired comparison based on expert judgments. The variables of coastal ecosystem health indicators in this synthesis consist of 3 level of variable, i.e. main variable, sub-variable and operational variable. As a result of assessment, coastal ecosystem health indicators consist of 3 main variables, i.e. State of Ecosystem, Pressure and Management. Main variables State of Ecosystem and Management obtain the same value i.e. 0.400, while Pressure value was 0.200. Each main variable consist of several sub-variable, i.e. coral reef, reef fish, mangrove and seagrass for State of Ecosystem; fisheries and marine tourism activity for Pressure; planning and regulation, institutional and also infrastructure and financing for Management. The highest value of sub-variable of main variable State of Ecosystem, Pressure and Management were coral reef (0.186); marine tourism pressure (0.133) and institutional (0.171), respectively. The highest value of operational variable of main variable State of Ecosystem, Pressure and Management were percent of coral cover (0.058), marine tourism pressure (0.133) and presence of zonation plan, regulation also socialization of monitoring program (0.53), respectively. Potential pressure from marine tourism activity is the variable that most affect the health of the ecosystem. The results of this research suggest that there is a need to develop stronger conservation strategies to facing with pressures from marine tourism

    In this study, the aim was to develop and test an urban green space indicator for public health, as proposed by the World Health Organisation (WHO) Regional Office for Europe, in order to support health and environmental policies. We defined the indicator of green space accessibility as a proportion of an urban population living within a certain distance from a green space boundary. We developed a Geographic Information System (GIS)-based method and tested it in three case studies in Malmö, Sweden; Kaunas, Lithuania; and Utrecht, The Netherlands. Land use data in GIS from the Urban Atlas were combined with population data. Various population data formats, maximum distances to green spaces, minimum sizes of green spaces, and different definitions of green spaces were studied or discussed. Our results demonstrated that with increasing size of green space and decreased distance to green space, the indicator value decreased. As compared to Malmö and Utrecht, a relatively bigger proportion of the Kaunas population had access to large green spaces, at both shorter and longer distances. Our results also showed that applying the method of spatially aggregated population data was an acceptable alternative to using individual data. Based on reviewing the literature and the case studies, a 300 m maximum linear distance to the boundary of urban green spaces of a minimum size of 1 hectare are recommended as the default options for the indicator. The indicator can serve as a proxy measure for assessing public accessibility to urban green spaces, to provide comparable data across Europe and stimulate policy actions that recognise the importance of green spaces for sustainable public health. © 2015 the Nordic Societies of Public Health.

    Despite considerable investment in digital health (DH) companies and a growing DH ecosystem, there are multiple challenges to testing and implementing innovative solutions. Health systems have recognized the potential of DH and have formed DH innovation centers. However, limited information is available on DH innovation center processes, best practices, or outcomes. This case report describes a DH innovation center process that can be replicated across health systems and defines and benchmarks process indicators to assess DH innovation center performance. The Brigham and Women's Hospital's Digital Health Innovation Group (DHIG) accelerates DH innovations from idea to pilot safely and efficiently using a structured process. Fifty-four DH innovations were accelerated by the DHIG process between July 2014 and December 2016. In order to measure effectiveness of the DHIG process, key process indicators were defined as 1) number of solutions that completed each DHIG phase and 2) length of time to complete each phase. Twenty-three DH innovations progressed to pilot stage and 13 innovations were terminated after barriers to pilot implementation were identified by the DHIG process. For 4 DH solutions that executed a pilot, the average time for innovations to proceed from DHIG intake to pilot initiation was 9 months. Overall, the DHIG is a reproducible process that addresses key roadblocks in DH innovation within health systems. To our knowledge, this is the first report to describe DH innovation process indicators and results within an academic health system. Therefore, there is no published data to compare our results with the results of other DH innovation centers. Standardized data collection and indicator reporting could allow benchmark comparisons across institutions. Additional opportunities exist for the validation of DH solution effectiveness and for translational support from pilot to implementation. These are critical steps to advance DH technologies and

The 402 persons (age 24-78 years were surveyed with the use of questionnaires MOS SF 36 and IPAQ. The highest quality of life and level of physical activity have teachers of physical culture. It is considered the quality of life of teachers of other subjects similar to persons with chronic diseases. The level of physical activity in leisure time was particularly low for teachers of Basic of Health and pedagogue-organizers. The teachers spent no more than 433 MET-min/ week for moderate- and vigorous-intensity activity. The level of physical activity of teachers (besides the physical education teachers was insufficient to improve health and indicate about low level of health-preserving competence.

    Maternal critical illness occurs in 1.2 to 4.7 of every 1000 live births in the United States and approximately 1 in 100 women who become critically ill will die. Patient characteristics and comorbid conditions are commonly summarized as an index or score for the purpose of predicting the likelihood of dying; however, most such indices have arisen from non-pregnant patient populations. We sought to systematically review comorbidity indices used in health administrative datasets of pregnant women, in order to critically appraise their measurement properties and recommend optimal tools for clinicians and maternal health researchers. We conducted a systematic search of MEDLINE and EMBASE to identify studies published from 1946 and 1947, respectively, to May 2017 that describe predictive validity of comorbidity indices using health administrative datasets in the field of maternal health research. We applied a methodological PubMed search filter to identify all studies of measurement properties for each index. Our initial search retrieved 8944 citations. The full text of 61 articles were identified and assessed for final eligibility. Finally, two eligible articles, describing three comorbidity indices appropriate for health administrative data remained: The Maternal comorbidity index, the Charlson comorbidity index and the Elixhauser Comorbidity Index. These studies of identified indices had a low risk of bias. The lack of an established consensus-building methodology in generating each index resulted in marginal sensibility for all indices. Only the Maternal Comorbidity Index was derived and validated specifically from a cohort of pregnant and postpartum women, using an administrative dataset, and had an associated c-statistic of 0.675 (95% Confidence Interval 0.647-0.666) in predicting mortality. Only the Maternal Comorbidity Index directly evaluated measurement properties relevant to pregnant women in health administrative datasets; however, it has only modest

    The study aims to determine soil health indicators of 46 coffee smallholder farmers in the area of Mbale, Mount Elgon region (1200m ~ 1900m) in the southeast of Uganda. Forty of these farmers are working under an organic farmers association and are certified. They are compared to six conventional coffee production systems. The organic farms are agroforestry systems, whereas the conventional coffee farms have nearly no shading trees. Topsoil and subsoil samples, in a depth of 0-20 and 20-40 cm were collected from each farm and analyzed. The following parameters were determined: pH (H2O), electric conductivity (EC), organic matter (OM), dissolved organic carbon (DOC), nitrate (NO3), phosphate (PO4) , sulfate (SO4) carbonate, dissolved total nitrogen (TN), plant available phosphorus (PO4 CAL), plant available potassium (K CAL) and cation exchange capacity (CEC). These parameters were used as indicators for soil health. A set of 33 quantitative and qualitative indicators was exclusively developed for coffee farmers to best describe a functioning ecosystem through social, economic and ecological indicators. These ecosystem-indicators were assessed through a questionnaire, carried out parallel to the soil sampling and further transformed into a scoring matrix where a scoring system from 0 to 100 points was used to normalize the collected data. There is a significant difference between the soil health indicators of organic and conventional coffee producers. The soil samples of conventional farms show higher pH values than those of organic farming systems referring to high turnover rates of the organic material. DOC release is on average higher in organic production systems. A major difference in the system is the higher plant available phosphate content, as well as a higher CEC in organic systems, which is due to the high organic matter input. The soil health indicator systems allowed to differentiate and to evaluate organic farms. Outlook Through the different management

    Human campylobacteriosis is the leading bacterial gastrointestinal illness in Canada; environmental transmission has been implicated in addition to transmission via consumption of contaminated food. Information about Campylobacter spp. occurrence at the watershed scale will enhance our understanding of the associated public health risks and the efficacy of source water protection strategies. The overriding purpose of this study is to provide a quantitative framework to assess and compare the relative public health significance of watershed microbial water quality associated with agricultural BMPs. A microbial monitoring program was expanded from fecal indicator analyses and Campylobacter spp. presence/absence tests to the development of a novel, 11-tube most probable number (MPN) method that targeted Campylobacter jejuni, Campylobacter coli, and Campylobacter lari. These three types of data were used to make inferences about theoretical risks in a watershed in which controlled tile drainage is widely practiced, an adjacent watershed with conventional (uncontrolled) tile drainage, and reference sites elsewhere in the same river basin. E. coli concentrations (MPN and plate count) in the controlled tile drainage watershed were statistically higher (2008-11), relative to the uncontrolled tile drainage watershed, but yearly variation was high as well. Escherichia coli loading for years 2008-11 combined were statistically higher in the controlled watershed, relative to the uncontrolled tile drainage watershed, but Campylobacter spp. loads for 2010-11 were generally higher for the uncontrolled tile drainage watershed (but not statistically significant). Using MPN data and a Bayesian modelling approach, higher mean Campylobacter spp. concentrations were found in the controlled tile drainage watershed relative to the uncontrolled tile drainage watershed (2010, 2011). A second-order quantitative microbial risk assessment (QMRA) was used, in a relative way, to identify

    To analyse the role of Mexico's mental health system governance in the development of mental health policies and programmes, from the perspective of its own actors. A map was developed for identifying the actors in Mexico's mental health system. A guide was designed for in-depth interviews, which were recorded and arranged in categories for their analysis. The Atlas-ti v.7 software was used for the organisation of qualitative data and Policy Maker v.4 was used to determine the position and influence of actors within the health system. The actors were identified according to their level of influence in mental health policies: high, medium and low. Actors with a high level of influence participate in national policies, actors with medium influence are involved in regional or local policies and the participation of actors with a low level of influence is considered marginal. This study facilitated understanding of governance in mental health. The level of influence of the actors directly affects the scope of governance indicators. Relevant data were obtained to improve policies in mental health care. Copyright © 2016 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

    To describe an index to identify inequities in living conditions and health and its relationship with health planning. Variables and indicators that would reflect demographic, economic, environment and education processes as well as supply and production of health services were applied for nondimensional scaling and clustering of 5,507 Brazilian municipalities. Data sources were the 2000 Census and the Brazilian Ministry of Health information systems. Z-score test statistic and cluster analysis were performed allowing to defining 4 groups of municipalities by living conditions. There was seen a polarization between the group with the best living conditions and health (Group 1) and the group with the worst living conditions (Group 4). Group 1 consisted of municipalities with larger populations while Group 4 comprised mainly the smallest municipalities. As for Brazilian macroregions, municipalities in Group 1 are clustered in the south and southeast and those in Group 4 are in the Northeast. The living conditions and health index comprises reality dimensions such as housing, environment and health which allows to identifying the most vulnerable municipalities and can provide input for setting priorities, and developing criteria for more equitable financing and resource allocation.

    Full Text Available Abstract Background It has been proposed that greater availability of primary medical care practitioners (GPs contributes to better population health. We evaluated whether measures of the supply and structure of primary medical services are associated with health and health care indicators after adjusting for confounding. Methods Data for the supply and structure of primary medical services and the characteristics of registered patients were analysed for 99 health authorities in England in 1999. Health and health care indicators as dependent variables included standardised mortality ratios (SMR, standardised hospital admission rates, and conceptions under the age of 18 years. Linear regression analyses were adjusted for Townsend score, proportion of ethnic minorities and proportion of social class IV/ V. Results Higher proportions of registered rural patients and patients ≥ 75 years were associated with lower Townsend deprivation scores, with larger partnership sizes and with better health outcomes. A unit increase in partnership size was associated with a 4.2 (95% confidence interval 1.7 to 6.7 unit decrease in SMR for all-cause mortality at 15–64 years (P = 0.001. A 10% increase in single-handed practices was associated with a 1.5 (0.2 to 2.9 unit increase in SMR (P = 0.027. After additional adjustment for percent of rural and elderly patients, partnership size and proportion of single-handed practices, GP supply was not associated with SMR (-2.8, -6.9 to 1.3, P = 0.183. Conclusions After adjusting for confounding with health needs of populations, mortality is weakly associated with the degree of organisation of practices as represented by the partnership size but not with the supply of GPs.

    Active video games (AVGs) have gained interest as a way to increase physical activity in children and youth. The effect of AVGs on acute energy expenditure (EE) has previously been reported; however, the influence of AVGs on other health-related lifestyle indicators remains unclear. This systematic review aimed to explain the relationship between AVGs and nine health and behavioural indicators in the pediatric population (aged 0-17 years). Online databases (MEDLINE, EMBASE, psycINFO, SPORTDiscus and Cochrane Central Database) and personal libraries were searched and content experts were consulted for additional material. Included articles were required to have a measure of AVG and at least one relevant health or behaviour indicator: EE (both habitual and acute), adherence and appeal (i.e., participation and enjoyment), opportunity cost (both time and financial considerations, and adverse events), adiposity, cardiometabolic health, energy intake, adaptation (effects of continued play), learning and rehabilitation, and video game evolution (i.e., sustainability of AVG technology). 51 unique studies, represented in 52 articles were included in the review. Data were available from 1992 participants, aged 3-17 years, from 8 countries, and published from 2006-2012. Overall, AVGs are associated with acute increases in EE, but effects on habitual physical activity are not clear. Further, AVGs show promise when used for learning and rehabilitation within special populations. Evidence related to other indicators was limited and inconclusive. Controlled studies show that AVGs acutely increase light- to moderate-intensity physical activity; however, the findings about if or how AVG lead to increases in habitual physical activity or decreases in sedentary behaviour are less clear. Although AVGs may elicit some health benefits in special populations, there is not sufficient evidence to recommend AVGs as a means of increasing daily physical activity.

    Full Text Available Aim: The aim of the research study is to identify the selected indicators of mental health, such as meaning of life, experience of well-being, hope, and feelings of loneliness and depression in the elderly participating in the University of the Third Age, in relation to their age and gender. Design: A quantitative descriptive study. Methods: The selection of respondents was deliberate. The sample consisted of 147 seniors with a mean age of 67.4 (± 4.9 years enrolled at the University of the Third Age at Jessenius Faculty of Medicine, Comenius University. Data were collected by means of self-assessment scales - the Life Meaningfulness Scale, Snyder´s Hope Scale, the Emotional Habitual Subjective Well-being Scale, the Loneliness Scale, and the Geriatric Depression Scale. Results: Seniors considered their life meaningful, and expressed a high level of hope. Their emotions were predominately positive. We identified low levels of loneliness and found no indication of depressed mood. We identified significant differences between men and women in evaluation indicators of mental health only in the frequency of positive emotions. Conclusion: The study indicates the presence of salutogenic factors affecting the mental health of the sample of seniors in the process of active aging. The results could form the basis for implementing preventive strategies in clinical nursing practice.

    The Qualitative aspect of health care delivery is one of the major factors in reducing morbidity and mortality in a health care setup. The expanding suburban secondary health care delivery facilities of the Municipal Corporation of Greater Mumbai are an important part of the healthcare backbone of Mumbai and therefore the quality of care delivered here needed standardization. The project was completed over a period of one year from Jan to Dec, 2013 and implemented in three phases. The framework with components and sub-components were developed and formats for data collection were standardized. The benchmarks were based on past performance in the same hospital and probability was used for development of normal range. An Excel spreadsheet was developed to facilitate data analysis. The indicators comprise of 3 components--Statutory Requirements, Patient care & Cure and Administrative efficiency. The measurements made, pointed to the broad areas needing attention. The Indicators for patient care and monitoring standards can be used as a self assessment tool for health care setups for standardization and improvement of delivery of health care services.

    To identify indicators of accuracy for consumer health information on the Internet. The results will help lay people distinguish accurate from inaccurate health information on the Internet. Several popular search engines (Yahoo, AltaVista, and Google) were used to find Web pages on the treatment of fever in children. The accuracy and completeness of these Web pages was determined by comparing their content with that of an instrument developed from authoritative sources on treating fever in children. The presence on these Web pages of a number of proposed indicators of accuracy, taken from published guidelines for evaluating the quality of health information on the Internet, was noted. Correlation between the accuracy of Web pages on treating fever in children and the presence of proposed indicators of accuracy on these pages. Likelihood ratios for the presence (and absence) of these proposed indicators. One hundred Web pages were identified and characterized as "more accurate" or "less accurate." Three indicators correlated with accuracy: displaying the HONcode logo, having an organization domain, and displaying a copyright. Many proposed indicators taken from published guidelines did not correlate with accuracy (e.g., the author being identified and the author having medical credentials) or inaccuracy (e.g., lack of currency and advertising). This method provides a systematic way of identifying indicators that are correlated with the accuracy (or inaccuracy) of health information on the Internet. Three such indicators have been identified in this study. Identifying such indicators and informing the providers and consumers of health information about them would be valuable for public health care.

    An environmental health inequality is a major public health concern in Europe. However just few studies take into account a large set of characteristics to analyze this problematic. The aim of this study was to identify and describe how socioeconomic, health accessibility and exposure factors accumulate and interact in small areas in a French urban context, to assess environmental health inequalities related to infant and neonatal mortality. Environmental indicators on deprivation index, proximity to high-traffic roads, green space, and healthcare accessibility were created using the Geographical Information System. Cases were collected from death certificates in the city hall of each municipality in the Nice metropolitan area. Using the parental addresses, cases were geocoded to their census block of residence. A classification using a Multiple Component Analysis following by a Hierarchical Clustering allow us to characterize the census blocks in terms of level of socioeconomic, environmental and accessibility to healthcare, which are very diverse definition by nature. Relation between infant and neonatal mortality rate and the three environmental patterns which categorize the census blocks after the classification was performed using a standard Poisson regression model for count data after checking the assumption of dispersion. Based on geographic indicators, three environmental patterns were identified. We found environmental inequalities and social health inequalities in Nice metropolitan area. Moreover these inequalities are counterbalance by the close proximity of deprived census blocks to healthcare facilities related to mother and newborn. So therefore we demonstrate no environmental health inequalities related to infant and neonatal mortality. Examination of patterns of social, environmental and in relation with healthcare access is useful to identify census blocks with needs and their effects on health. Similar analyzes could be implemented and considered

    To develop performance indicators for outsourcing clinical laboratory services, based on information systems and public administrative records. In the municipality of Rio de Janeiro, Southern Brazil, the public health laboratory network comprised 33 laboratories with automated equipment (but no integrated information system), 90 primary care units (where sample collection was performed) and 983 employees. Information records were obtained from the administrative records of the Budget Information System for Public Health and the Outpatient and Hospital Information System of the Unified Health System. Performance indicators (production, productivity, usage and costs) were generated from data collected routinely from 2006 to 2008. The variations in production, costs and unit prices for tests were analyzed by Laspeyres and Paasche indices, which specifically measure laboratory activity, and by the Consumer Price Index from the Brazilian Institute of Geography and Statistics. A total of 10,359,111 tests were performed in 2008 (10.6% increase over 2006), and the test/employee ratio grew by 8.6%. The costs of supplies, wages and providers increased by 2.3%, 45.4% and 18.3%, respectively. The laboratory tests per visit and hospitalizations increased by 10% and 20%, respectively. The direct costs totaled R$ 63.2 million in 2008, representing an increase of 22.2% in current values during the period analyzed. The direct costs deflated by the Brazilian National Consumer Price Index (9.5% for the period) showed an 11.6% increase in production volumes. The activity-specific volume index, which considers changes in the mix of tests, showed increases of 18.5% in the test price and 3.1% in the production volume. The performance indicators, particularly the specific indices for volume and price of activity, constitute a baseline of performance potential for monitoring private laboratories and contractors. The economic performance indicators demonstrated the need for network

    We now know that efficient public policies for cancer control need to be global and take into account each and all the factors involved: economics and level of development, style of life and risk factors, access to screening, effectiveness of the care-providing system. A very simple scorecard is proposed, based on publicized public health indicators, which allows a comparison between European countries. We extracted 49 indicators from public databases and literature concerning 22 European countries. We made correlation calculations in order to identify relevant indicators from which a global score was extracted. Using a hierarchical clustering method we were then able to identify subsets of homogeneous countries. A 7 indicator scorecard was drawn up: national gross product, scientific production, smoking rate, breast screening participating rate, all cancer mortality rate (male population), 5 years relative survival for colorectal cancer and life expectancy at birth. A global score shows: 1) the better positioned countries: Switzerland, Sweden, Finland and France; 2) the countries where cancer control is less effective: Estonia, Hungary, Poland and Slovakia. Three subsets of countries with a fairly similar profile were identified: a high level of means and results group; a high level of means but a medium level of results group; and a low level of means and results group. This work emphasizes dramatically heterogeneous situations between countries. A follow-up, using a reduced but regularly updated set of public health indicators, would help induce an active European policy for cancer control.

    Mastitis is an important disease in dairy goat production. Subclinical mastitis is common in goats and is mainly caused by contagious bacteria. Several methods to diagnose mastitis in goats are available but have not all been investigated in healthy udders and at different stages of lactation....... The purpose of the study was to investigate the variation in some udder health indicators at different stages of lactation in goats without intramammary infection (IMI). The udder health indicators were: somatic cell counts (SCC) measured by DeLaval Cell Counter (DCC) and estimated by California Mastitis Test...... (CMT), lactate dehydrogenase (LDH) activity, N-acetyl-β-d-glucoseaminidase (NAGase) activity and alkaline phosphatase (AP) activity. Milk samples from twenty-four clinically healthy dairy goats were collected on two consecutive days in early, mid and late lactation. At milking, each goat's udder half...

    The objective of this study was to illustrate the importance of combining Health Usage Monitoring Systems (HUMS) data with usage monitoring system data when detecting rotorcraft transmission health. Three gear sets were tested in the NASA Glenn Spiral Bevel Gear Fatigue Rig. Damage was initiated and progressed on the gear and pinion teeth. Damage progression was measured by debris generation and documented with inspection photos at varying torque values. A contact fatigue analysis was applied to the gear design indicating the effect temperature, load and reliability had on gear life. Results of this study illustrated the benefits of combining HUMS data and actual usage data to indicate progression of damage for spiral bevel gears.

    In response to the call for empirical evidence of a connection between leading and lagging indicators of occupational health and safety (OHS), the first aim of the current research is to consider the association between leading and lagging indicators of OHS. Our second aim is to investigate the moderating effect of safety leadership on the association between leading and lagging indicators. Data were collected from 3578 employees nested within 66 workplaces. Multi-level modelling was used to test the two hypotheses. The results confirm an association between leading and lagging indicators of OHS as well as the moderating impact of middle management safety leadership on the direct association. The association between leading and lagging indicators provides OHS practitioners with useful information to substantiate efforts within organisations to move away from a traditional focus on lagging indicators towards a preventative focus on leading indicators. The research also highlights the important role played by middle managers and the value of OHS leadership development and investment at the middle management level. Copyright © 2016 Elsevier Ltd.

    Full Text Available Introduction: Various types of software are used in health care organizations to manage information and care processes. The quality of software has been an important concern for both health authorities and designers of Health Information Technology. Thus, assessing the effect of software quality on the performance quality of healthcare institutions is essential. Method: The most important health care quality indicators in relation to software quality characteristics are provided via an already performed literature review. ISO 9126 standard model is used for definition and integration of various characteristics of software quality. The effects of software quality characteristics and sub-characteristics on the healthcare indicators are evaluated through expert opinion analyses. A questionnaire comprising of 126 questions of 10-point Likert scale was used to gather opinions of experts in the field of Medical/Health Informatics. The data was analyzed using Structural Equation Modeling. Results: Our findings showed that software Maintainability was rated as the most effective factor on user satisfaction (R2 =0.89 and Functionality as the most important and independent variable affecting patient care quality (R2 =0.98. Efficiency was considered as the most effective factor on workflow (R2 =0.97, and Maintainability as the most important factor that affects healthcare communication (R2 =0.95. Usability and Efficiency were rated as the most effectual factor affecting patient satisfaction (R2 =0.80, 0.81. Reliability, Maintainability, and Efficiency were considered as the main factors affecting care costs (R2 =0.87, 0.74, 0.87. Conclusion: We presented a new model based on ISO standards. The model demonstrates and weighs the relations between software quality characteristics and healthcare quality indicators. The clear relationships between variables and the type of the metrics and measurement methods used in the model make it a reliable method to assess

    Full Text Available Abstract Background Outcome quality indicators are rarely used to evaluate mental health services because most jurisdictions lack clinical data systems to construct indicators in a meaningful way across mental health providers. As a result, important information about the effectiveness of health services remains unknown. This study examined the feasibility of developing mental health quality indicators (MHQIs using the Resident Assessment Instrument - Mental Health (RAI-MH, a clinical assessment system mandated for use in Ontario, Canada as well as many other jurisdictions internationally. Methods Retrospective analyses were performed on two datasets containing RAI-MH assessments for 1,056 patients from 7 facilities and 34,788 patients from 70 facilities in Ontario, Canada. The RAI-MH was completed by clinical staff of each facility at admission and follow-up, typically at discharge. The RAI-MH includes a breadth of information on symptoms, functioning, socio-demographics, and service utilization. Potential MHQIs were derived by examining the empirical patterns of improvement and incidence in depressive symptoms and cognitive performance across facilities in both sets of data. A prevalence indicator was also constructed to compare restraint use. Logistic regression was used to evaluate risk adjustment of MHQIs using patient case-mix index scores derived from the RAI-MH System for Classification of Inpatient Psychiatry. Results Subscales from the RAI-MH, the Depression Severity Index (DSI and Cognitive Performance Scale (CPS, were found to have good reliability and strong convergent validity. Unadjusted rates of five MHQIs based on the DSI, CPS, and restraints showed substantial variation among facilities in both sets of data. For instance, there was a 29.3% difference between the first and third quartile facility rates of improvement in cognitive performance. The case-mix index score was significantly related to MHQIs for cognitive performance

    The MMR - maternal mortality ratio - has risen from obscurity to become a major global health indicator, even appearing as an indicator of progress towards the global Sustainable Development Goals. This has happened despite intractable challenges relating to the measurement of maternal mortality. Even after three decades of measurement innovation, maternal mortality data are widely presumed to be of poor quality, or, as one leading measurement expert has put it, 'guilty until proven innocent'. This paper explores how and why leading epidemiologists, demographers and statisticians have devoted the better part of the last three decades to producing ever more sophisticated and expensive surveys and mathematical models of globally comparable MMR estimates. The development of better metrics is publicly justified by the need to know which interventions save lives and at what cost. We show, however, that measurement experts' work has also been driven by the need to secure political priority for safe motherhood and by donors' need to justify and monitor the results of investment flows. We explore the many effects and consequences of this measurement work, including the eclipsing of attention to strengthening much-needed national health information systems. We analyse this measurement work in relation to broader political and economic changes affecting the global health field, not least the incursion of neoliberal, business-oriented donors such as the World Bank and the Bill and Melinda Gates Foundation whose institutional structures have introduced new forms of administrative oversight and accountability that depend on indicators.

    In most health care organizations there is still insufficient awareness for recognizing and treating malnourished patients. To gain more insight into nutritional care policies in Dutch health care organizations, this study investigated screening, treatment, and other quality indicators of nutritional care. In 2007 a cross-sectional multicenter study was performed that included 20 255 patients (hospitals, n = 6021; nursing homes, n = 11 902; home care, n = 2332). A standardized questionnaire was used to study nutritional screening and treatment at the patient level and quality indicators at institutional and ward levels (e.g., malnutrition guidelines/protocols, nutritional education, and weighing policy). Nutritional screening was performed more often in nursing homes (60.2%) than in hospitals (40.3%) and home care (13.9%, P hospitals, and home care. At ward level nursing homes focused more on the quality of nutritional care than did hospitals and home care, especially with respect to controlling the use of nutritional guidelines (54.6%, P malnutrition is still a considerable problem in one of every five patients in all participating health care settings. It furthermore demonstrates that recognizing and treating malnutrition continues to be problematic. To target the problem of malnutrition adequately, more awareness is needed of the importance of nutritional screening, appropriate treatment, and other nutritional quality indicators.

    Poor mental health functioning among persons living with HIV (PLHIV) has gained considerable attention particularly in low-income countries that disproportionately carry the global HIV/AIDS burden. Fewer studies, however, have examined the relationship between poverty indicators and mental health among PHLIV in India. Based on this cross-sectional study of 196 HIV-seropositive adults who received medical services at Shalom AIDS Project in Delhi, India, structural equation modeling and mediation analysis were employed to estimate the associations between poverty indices (household asset index, food security, unemployment, water treatment, sanitation), HIV-health factors (illness in the past 3 months, co-morbid medical conditions), and psychological distress. In the final model, ownership of fewer household assets was associated with higher levels of food insecurity, which in turn was associated with higher psychological distress. Also, the household asset index, food insecurity, and unemployment had a larger effect on psychological distress than new opportunistic infections. These findings build on increasing evidence that support concerted efforts to design, evaluate, and refine HIV mental health interventions that are mainstreamed with livelihood programming in high poverty regions in India.

    The relationship between the number of withdrawn/restricted drugs and socioeconomic, health, and welfare indicators were investigated in a comprehensive review of drug regulation information in the United Nations (UN) countries. A total of of 362 drugs were withdrawn and 248 were restricted during 1950-2010, corresponding to rates of 12.02 ± 13.07 and 5.77 ± 8.69 (mean ± SD), respectively, among 94 UN countries. A socioeconomic, health, and welfare analysis was performed for 33 OECD countries for which data were available regarding withdrawn/restricted drugs. The gross domestic product (GDP) per capita, GDP per hour worked, health expenditure per GDP, and elderly population rate were positively correlated with the numbers of withdrawn and restricted drugs (P < 0.05), while the out-of-pocket health expenditure payment rate was negatively correlated. The number of restricted drugs was also correlated with the rate of drug-related deaths (P < 0.05). The World Bank data cross-validated the findings of 33 OECD countries. The lists of withdrawn/restricted drugs showed markedly poor international agreement between them (Fleiss's kappa = -0.114). Twenty-seven drugs that had been withdrawn internationally by manufacturers are still available in some countries. The wide variation in the numbers of drug withdrawals and restrictions among countries indicates the need to improve drug surveillance systems and regulatory communication networks.

    This analysis explored the effect of timing, sequencing, and change in preconception health across adolescence and young adulthood on racial/ethnic disparities in birth weight in a diverse national cohort of young adult women. Data came from Waves I (1994-1995), III (2001-2002), and IV (2007-2008) of the National Longitudinal Study of Adolescent Health. Eligibility was restricted to all singleton live births to female non-Hispanic White, non-Hispanic Black, Mexican-origin Latina, or Asian/Pacific Islander participants (n = 3,014) occurring between the Wave III (ages 18-26 years) and IV (ages 24-32 years) interviews. Birth weight was categorized into low (4,000 g). Preconception health indicators were cigarette smoking, heavy alcohol consumption, overweight or obesity, and inadequate physical activity, measured in adolescence (Wave I, ages 11-19 years) and early adulthood (Wave III) and combined into four-category variables to capture the timing and sequencing of exposure. Measures of preconception health did not explain the Black-White disparity in low birth weight, which increased after adjustment for confounders (odds ratio [OR], 2.17; 95% confidence interval [CI], 1.33-3.53) and effect modification by overweight/obesity (OR, 3.58; 95% CI, 1.65-7.78). A positive association between adult-onset overweight/obesity and macrosomia was modified by race (OR, 3.83; 95% CI, 1.02-14.36 for Black women). This longitudinal analysis provides new evidence on preconception health and racial/ethnic disparities in birth weight. Specifically, it indicates that interventions focused on prevention of overweight/obesity and maintenance of healthy weight during the transition to adulthood, especially among Black females, may be warranted.

    Community health planning requires identification of the level of access to care and factors which affect the differentials in use of health services. In formulating strategies or alternatives for planning, some assessment of the current level or patterns of health services must be made. It is this element of the planning process that is addressed in this paper. In this study sixty-five specifically designated areas (medical market areas) in the Province of Quebec, Canada were selected. The analysis was performed using data obtained from a large scale study of physicians' responses to the introduction of universal medical care insurance in Quebec. Our analysis offered an opportunity to observe the impact of Medicare on access to care for those thought to be underserved.

    Although higher microbial concentrations have been reported in sediments than in the overlying water column, most quantitative microbial risk assessment (QMRA) studies have not clearly indicated the contribution of sediment-borne pathogens to estimated risks. Thus, the present study aimed at determining the public health risk associated with exposure to pathogenic bacteria in polluted river water under undisturbed conditions and conditions of sediment resuspension in the Apies River, Gauteng, South Africa. Microbial pathogens were isolated and identified using culture and molecular methods. The beta-Poisson dose-response model was used to estimate the probability of infection (Pi) with the various pathogens, following accidental/intentional ingestion of 1mL or 100mL (or 50mL) of untreated river water. Mean wet season Escherichia coli counts ranged between 5.8E+01 and 8.8E+04MPN/100mL (water column) and between 2.40E+03 and 1.28E+05MPN/100mL (sediments). Mean dry season E. coli counts ranged between 5.11E+00 and 3.40E+03MPN/100mL (water column) and between 5.09E+00 and 6.30E+03MPN/100mL (sediments). Overall (water and sediments) Vibrio cholerae was the most detected pathogen (58.8%) followed by Salmonella spp. (23.9%) and Shigella (10.1%). Ingestion of 1mL of river water could lead to 0%-4% and 1%-74% Pi with E. coli during the dry and wet season, respectively. During the dry season, the Pi with V. cholerae, Salmonella spp. and Shigella spp. were 0%-1.39%, 0%-4.11% and 0%-0.16% respectively, depending on volume of water ingested. The risks of infections with all microorganisms increased during the wet season. A 2-log increase in water E. coli count following sediments disturbance led to approximately 10 times higher Pi with E. coli than when sediments were undisturbed. Therefore, the use of the untreated water from the Apies River for drinking, household purposes or recreational activities poses a potential health risk to the users of the river. Copyright © 2016

In electronic patient records, many diagnostic and procedural codes are registered, but unfortunately, it is usually not specified which one is the reason for transfusion. Therefore, a method is needed to determine the most likely indication for transfusion in an automated way.Study design and methods: An algorithm to identify the most likely transfusion indication was developed and evaluated against a gold standard based on the review of medical records for 234 cases by 2 experts. In a second step, information on misclassification was used to fine-tune the initial algorithm. The adapted algorithm predicts, out of all data available, the most likely indication for transfusion using information on medical specialism, surgical procedures, and diagnosis and procedure dates relative to the transfusion date.Results: The adapted algorithm was able to predict 74.4% of indications in the sample correctly (extrapolated to the full data set 75.5%.

    Characterize geographical indicators in relation to their usefulness in measuring regional inequities, identify and describe areas according to their degree of geographical accessibility to primary health care centers (PHCCs), and detect populations at risk from the perspective of access to primary care. Analysis of spatial accessibility using geographic information systems (GIS) involved three aspects: population without medical coverage, distribution of PHCCs, and the public transportation network connecting them. The development of indicators of demand (real, potential, and differential) and analysis of territorial factors affecting population mobility enabled the characterization of PHCCs with regard to their environment, thereby contributing to local and regional analysis and to the detection of different zones according to regional connectivity levels. Indicators developed in a GIS environment were very useful in analyzing accessibility to PHCCs by vulnerable populations. Zoning the region helped identify inequities by differentiating areas of unmet demand and fragmentation of spatial connectivity between PHCCs and public transportation.

    Background Previous analyses have shown the individual correlations between poverty, health and satellite-derived vegetation indices such as the normalized difference vegetation index (NDVI). However, generally these analyses did not explore the statistical interconnections between poverty, health outcomes and NDVI. Methods In this research aspatial methods (principal component analysis) and spatial models (variography, factorial kriging and cokriging) were applied to investigate the correlations and spatial relationships between intensity of poverty, health (expressed as child mortality and undernutrition), and NDVI for a large area of West Africa. Results This research showed that the intensity of poverty (and hence child mortality and nutrition) varies inversely with NDVI. From the spatial point-of-view, similarities in the spatial variation of intensity of poverty and NDVI were found. Conclusions These results highlight the utility of satellite-based metrics for poverty models including health and ecological components and, in general for large scale analysis, estimation and optimisation of multidimensional poverty metrics. However, it also stresses the need for further studies on the causes of the association between NDVI, health and poverty. Once these relationships are confirmed and better understood, the presence of this ecological component in poverty metrics has the potential to facilitate the analysis of the impacts of climate change on the rural populations afflicted by poverty and child mortality.

    Full Text Available Urban green spaces can yield considerable health benefits to urban residents. Assessing these health benefits is a key step for managing urban green spaces for human health and wellbeing in cities. In this study, we assessed the change of health benefits generated by urban green spaces in 28 megacities worldwide between 2005 and 2015 by using availability and accessibility as proxy indicators. We first mapped land covers of 28 megacities using 10,823 scenes of Landsat images and a random forest classifier running on Google Earth Engine. We then calculated the availability and accessibility of urban green spaces using the land cover maps and gridded population data. The results showed that the mean availability of urban green spaces in these megacities increased from 27.63% in 2005 to 31.74% in 2015. The mean accessibility of urban green spaces increased from 65.76% in 2005 to 72.86% in 2015. The increased availability and accessibility of urban green spaces in megacities have brought more health benefits to their residents.

    This article presents a series of pertinent predictors of financial failure based on analysis of solvent and bankrupt health systems to identify which financial measures show the clearest distinction between success and failure. Early warning signals are evident from the longitudinal analysis as early as five years before bankruptcy. The data source includes seven years of annual statements filed with the Securities and Exchange Commission by 13 health systems before they filed bankruptcy. Comparative data were compiled from five solvent health systems for the same seven-year period. Seven financial solvency ratios are included in this study, including four cash liquidity measures, two leverage measures, and one efficiency measure. The results show distinct financial trends between solvent and bankrupt health systems, in particular for the operating-cash-flow-related measures, namely Ratio 1: Operating Cash Flow Percentage Change, from prior to current period; Ratio 2: Operating Cash Flow to Net Revenues; and Ratio 4: Cash Flow to Total Liabilities, indicating sensitivity in the hospital industry to cash flow management. The high dependence on credit from third-party payers is cited as a reason for this; thus, there is a great need for cash to fund operations. Five managerial policy implications are provided to help health system managers avoid financial solvency problems in the future.

    The aim of the present study was to examine the maternal and neonatal birth risk indicator and their relationship with the outcome of pregnancy. This retrospective descriptive study was conducted in a selective month of 2008, 2009, and 2010. The birth risk indicators of maternal and neonatal health were collected from the medical records. There were 385, 349 and 334 deliveries in a selective month of 2008, 2009, and 2010. There was neither maternal mortality, nor cardiovascular failure in the present study period. Three main indication of inductions of labor were premature rupture of membrane (up to 4.0%), diabetes mellitus (up to 2.0%), and postdate (up to 1.3%). The first two conditions had statistical significance in September 2009 (p = 0.0334 and 0.0053 respectively). Whereas, the three major indications of cesarean section were previous cesarean section (12.5 to 21.9%), failure to progress due to protracted/arrest of labor pattern with/without rupture of membrane and augmented labor (2.4 to 7.5%), and fetal distress (1.1 to 4.2%). The rates of low birth weight, less than 2,500 grams, were varied from 5.2 to 6.9%. The respiratory distress syndrome (RDS) related to repeat cesarean section was encountered up to 3.6%, as well as the RDS related to induction of labor was up to 1.6%. The birth risk indicators reflect the outcome of pregnancy, however the development of additional key indicators for perinatal health care outcome are required.

    Full Text Available Data collected on germination index, temperature, moisture content, pH, total viable count, total coliform count and total fungi count were determined during composting in HV and FA systems at VREL Farms for a period of thirteen weeks and analysed to ascertain the effects of temperature, moisture and pH on compost maturity and microbial survival. There were no significant differences in germination index, pH and moisture content values for both systems as ANOVA results at α = 5% yielded p-values of 0.17, 0.98 and 0.13 respectively. Moisture content and pH values ranged between 40%-70% and 7.20 - 8.30 respectively. Temperature values recorded however were significantly different (p-value = 1.2 x 10-5, α = 5% in both systems and affected the microbial distribution during the process. The temperature recorded in HV and FA systems ranged between 45.19 ºC – 65.44 ºC and 29.00 ºC – 50.83ºC respectively. Germination Index values were >150% in different systems at the end of week 12. Listeria spp., known to be zoonotic, and Staphylococcus spp. survived in compost processed in FA system; and Penicillium spp. in both systems.

  2. Use of country of birth as an indicator of refugee background in health datasets

    2014-01-01

    Background Routine public health databases contain a wealth of data useful for research among vulnerable or isolated groups, who may be under-represented in traditional medical research. Identifying specific vulnerable populations, such as resettled refugees, can be particularly challenging; often country of birth is the sole indicator of whether an individual has a refugee background. The objective of this article was to review strengths and weaknesses of different methodological approaches to identifying resettled refugees and comparison groups from routine health datasets and to propose the application of additional methodological rigour in future research. Discussion Methodological approaches to selecting refugee and comparison groups from existing routine health datasets vary widely and are often explained in insufficient detail. Linked data systems or datasets from specialized refugee health services can accurately select resettled refugee and asylum seeker groups but have limited availability and can be selective. In contrast, country of birth is commonly collected in routine health datasets but a robust method for selecting humanitarian source countries based solely on this information is required. The authors recommend use of national immigration data to objectively identify countries of birth with high proportions of humanitarian entrants, matched by time period to the study dataset. When available, additional migration indicators may help to better understand migration as a health determinant. Methodologically, if multiple countries of birth are combined, the proportion of the sample represented by each country of birth should be included, with sub-analysis of individual countries of birth potentially providing further insights, if population size allows. United Nations-defined world regions provide an objective framework for combining countries of birth when necessary. A comparison group of economic migrants from the same world region may be appropriate

    This study was aimed at analysing the association between socioeconomic indicators and adolescents' physical activity and health-related fitness. The study involved 716 adolescents from both genders whose age ranged from 10 to 18 years-old (46.8% male) who answered a questionnaire for estimating their habitual physical activity, socioeconomic status; two health-related physical fitness tests were also performed. The socioeconomic indicators analysed concerned their parents' educational level and the number of bathrooms, TVs, cars, housemaids, refrigerators and freezers in their homes. A positive association was found between paternal education (PR=1.61 (range 1.27-2.10) and 1.41 (1.10-1.83)) and housemaids (PR=1.97 (1.04-3.81) and 1.92 (1.05-3.52)) with recommended physical activity and leisure time physical activity, respectively. The number of cars (PR=1.48: 1.02-2.19) and freezers (PR=1.88: 1.12-3.18) was positively associated with leisure time physical activity and the number of TVs negatively so (PR=0.75: 0.63-0.89). The number of TVs (PR=0.80: 0.67-0.96) and cars (PR=0.70: 0.55-0.89) was negatively associated with cardiorespiratory fitness whilst paternal education (PR=1.17: 1.00-1.37) and the number of bathrooms in the home (PR=1.25: 1.02-1.54) were positively associated with muscular strength. Physical activity and health-related physical fitness were associated with socioeconomic status. However, such association depended on the socioeconomic indicator being analysed. Caution should be taken when analysing studies which use different socioeconomic indicators.

    Full Text Available We have been developing a method of evaluating the mental health condition of a person based on the sound of their voice. Currently, we have applied this technology to create a smartphone application that shows the vitality and the mental activity as mental health condition indices. Using voice to measure one’s mental health condition is a non-invasive method. Moreover, this application can be used continually through a smartphone call. Unlike a periodic checkup every year, it could be used for monitoring on a daily basis. The purpose of this study is to compare the vitality index to the widely used Beck depression inventory (BDI and to evaluate its validity. This experiment was conducted at the Center of Innovation Program of the University of Tokyo with 50 employees of one corporation as participants between early December 2015 and early February 2016. Each participant was given a smartphone with our application that recorded his/her voice automatically during calls. In addition, the participants had to read and record a fixed phrase daily. The BDI test was conducted at the beginning of the experimental period. The vitality index was calculated based on the voice data collected during the first two weeks of the experiment and was considered as the vitality index at the time when the BDI test was conducted. When the vitality and the mental activity indicators were compared to BDI score, we found that there was a negative correlation between the BDI score and these indices. Additionally, these indices were a useful method to discriminate a participant of high risk of disease with a high BDI score. And the mental activity index shows a higher performance than the vitality index.

    Full Text Available Abstract Background & aim: Nearly a decade the World Health Organization has tried to provide a unique definition of community mental health. But due to the complexity of psychosocial and cultural context, it is not provided. The purpose of the study was to determine indexes community mental health of children and adolescents in the province of Kohgiluyeh and Boyerahmad. Methods: This study was conducted as a hybrid approach (qualitative and quantitative. Delphi technique was used in qualitative research. In the current study, 31 experts, children and adolescents of Social Welfare organizations were selected as snowball method throughout the province of Kohgiluyeh & Boyerahmad. The primary data to run the Delphi Technique was gathered in three stages from the participants. The quantitative data were analyzed using factor analysis. Results: The results indicated that the main indicators of psychosocial health lie in intrapersonal (emotional self-awareness, risk-taking and self-respect, interpersonal (participation, social responsibility, and social relationships, stress (stress management and controlling emotions and adaptability (flexibility and happiness components. The results also showed that decreasing gender-related discriminations and rise in the educational level of parents are the major strengths and lack of required standards in child-care centers, lack of involvement of young adolescents in decision-making and lack of social skills in families are the major weaknesses of psychosocial health. Conclusion: Given the right conditions, and in order to safeguard children and adolescents against the grave consequences awaiting them, the organizations charged with the responsibility should raise the children and adolescents in such a way that they meet the professional needs of the society and feel responsible when it comes to these responsibilities and commitments.

    Universal Health Coverage (UHC), referring to access to healthcare without financial burden, has received renewed attention in global health spheres. UHC is a potential goal in the post-2015 development agenda. Monitoring of progress towards achieving UHC is thus critical at both country and global level, and a monitoring framework for UHC was proposed by a joint WHO/World Bank discussion paper in December 2013. The aim of this study was to determine the feasibility of the framework proposed by WHO/World Bank for global UHC monitoring framework in Kenya. The study utilised three documents--the joint WHO/World Bank UHC monitoring framework and its update, and the Bellagio meeting report sponsored by WHO and the Rockefeller Foundation--to conduct the research. These documents informed the list of potential indicators that were used to determine the feasibility of the framework. A purposive literature search was undertaken to identify key government policy documents and relevant scholarly articles. A desk review of the literature was undertaken to answer the research objectives of this study. Kenya has yet to establish an official policy on UHC that provides a clear mandate on the goals, targets and monitoring and evaluation of performance. However, a significant majority of Kenyans continue to have limited access to health services as well as limited financial risk protection. The country has the capacity to reasonably report on five out of the seven proposed UHC indicators. However, there was very limited capacity to report on the two service coverage indicators for the chronic condition and injuries (CCIs) interventions. Out of the potential tracer indicators (n = 27) for aggregate CCI-related measures, four tracer indicators were available. Moreover the country experiences some wider challenges that may impact on the implementation and feasibility of the WHO/World Bank framework. The proposed global framework for monitoring UHC will only be feasible in Kenya if

    It is clear that globalization is something more than a purely economic phenomenon manifesting itself on a global scale. Among the visible manifestations of globalization are the greater international movement of goods and services, financial capital, information and people. In addition, there are technological developments, more transboundary cultural exchanges, facilitated by the freer trade of more differentiated products as well as by tourism and immigration, changes in the political landscape and ecological consequences. In this paper, we link the Maastricht Globalization Index with health indicators to analyse if more globalized countries are doing better in terms of infant mortality rate, under-five mortality rate, and adult mortality rate. The results indicate a positive association between a high level of globalization and low mortality rates. In view of the arguments that globalization provides winners and losers, and might be seen as a disequalizing process, we should perhaps be careful in interpreting the observed positive association as simple evidence that globalization is mostly good for our health. It is our hope that a further analysis of health impacts of globalization may help in adjusting and optimising the process of globalization on every level in the direction of a sustainable and healthy development for all.

    Results: Generally, 75% production centers had favorable hygienic status and 25% had slightly favorable hygienic status. According to obtained results, hygienic status of production centers had relatively favorable and favorable conditions and only in January and February in 31.3% and 18.8% processing hall and 12.5% product store was in a very favorable hygienic status. The results showed that in terms of environmental health status, 62.5% production centers in raw materials store part, 66.66% in production processing hall, 20.83% in packaging hall, 60.41% in product store and 37.5% in bathrooms had favorable status. Based on the results, hygienic status of bathrooms and processing hall achieved lowest and highest score, respectively. Statistical analysis showed that between hygienic status and production rate (p=0.411 there is no significant relationship. Conclusion: The results of this study indicate that the halva and tahini production centers of Ardakan city in terms of environmental health indicators had slightly favorable status to favorable and none of the production centers had not very favorable conditions. The results of this study can be used to improve health status of halva and tahini production centers.

    Despite substantial investment in health capacity building in developing countries, evaluations of capacity building effectiveness are scarce. By analysing projects in Africa that had successfully built sustainable capacity, we aimed to identify evidence that could indicate that capacity building was likely to be sustainable. Four projects were selected as case studies using pre-determined criteria, including the achievement of sustainable capacity. By mapping the capacity building activities in each case study onto a framework previously used for evaluating health research capacity in Ghana, we were able to identify activities that were common to all projects. We used these activities to derive indicators which could be used in other projects to monitor progress towards building sustainable research capacity. Indicators of sustainable capacity building increased in complexity as projects matured and included- early engagement of stakeholders; explicit plans for scale up; strategies for influencing policies; quality assessments (awareness and experiential stages)- improved resources; institutionalisation of activities; innovation (expansion stage)- funding for core activities secured; management and decision-making led by southern partners (consolidation stage).Projects became sustainable after a median of 66 months. The main challenges to achieving sustainability were high turnover of staff and stakeholders, and difficulties in embedding new activities into existing systems, securing funding and influencing policy development. Our indicators of sustainable capacity building need to be tested prospectively in a variety of projects to assess their usefulness. For each project the evidence required to show that indicators have been achieved should evolve with the project and they should be determined prospectively in collaboration with stakeholders.

    To explore patients' perceptions of health-care built environments, to assess how they perceived health-care built facilities and designs. To develop a set of patient-centred indicators by which to appraise future health-care designs. Qualitative and quantitative methodologies, including futures group conferencing, autophotographic study, novice-expert exchanges and a questionnaire survey of a representative sample of past patients. The research was carried out at Salford Royal Hospitals NHS Trust (SRHT), Greater Manchester, UK, selected for the study because of planned comprehensive redevelopment based on the new NHS vision for hospital care and service delivery for the 21st century. Participants included 35 patients who took part in an autophotographic study, eight focus groups engaged in futures conferencing, a sample of past inpatients from the previous 12 months that returned 785 completed postal questionnaires. The futures group provided suggestions for radical improvements which were categorized into transport issues; accessibility and mobility; ground and landscape designs; social and public spaces; homeliness and assurance; cultural diversity; safety and security; personal space and access to outside. Patients' autophotographic study centred on: the quality of the ward design, human interactions, the state and quality of personal space, and facilities for recreation and leisure. The novices' suggestions were organized into categories of elemental factors representing patient-friendly designs. Experts from the architectural and surveying professions and staff at SRHT in turn considered these categories and respective subsets of factors. They agreed with the novices in terms of the headings but differed in prioritizing the elemental factors. The questionnaire survey of past patients provided opinions about ward designs that varied according to where they stayed, single room, bay ward or long open ward. The main concerns were limitation of private space

    To analyze the relationship of legal status and employment conditions with health indicators in foreign-born and Spanish-born workers in Spain. Cross-sectional study of 1,849 foreign-born and 509 Spanish-born workers (2008-2009, ITSAL Project). Considered employment conditions: permanent, temporary and no contract (foreign-born and Spanish-born); considered legal statuses: documented and undocumented (foreign-born). Joint relationships with self-rated health (SRH) and mental health (MH) were analyzed via logistical regression. When compared with male permanently contracted Spanish-born workers, worse health is seen in undocumented foreign-born, time in Spain ≤3 years (SRH aOR 2.68, 95% CI 1.09-6.56; MH aOR 2.26, 95% CI 1.15-4.42); in Spanish-born, temporary contracts (SRH aOR 2.40, 95% CI 1.04-5.53); and in foreign-born, temporary contracts, time in Spain >3 years (MH: aOR 1.96, 95% CI 1.13-3.38). In females, highest self-rated health risks are in foreign-born, temporary contracts (aOR 2.36, 95% CI 1.13-4.91) and without contracts, time in Spain >3 years (aOR 4.63, 95% CI 1.95-10.97). Contract type is a health determinant in both foreign-born and Spanish-born workers. This study offers an uncommon exploration of undocumented migration and raises methodological issues to consider in future research.

    Numerous experiments under controlled conditions and extensive investigation of waterfowl die-offs have demonstrated that exposure to lead from spent gunshot is highly detrimental to the health of waterfowl. However, few studies have focused on examining the more subtle sub-lethal effects of lead toxicity on ducks in non-experimental settings. In our study, the health of ducks exposed to varying amounts of lead under natural conditions was assessed by correlating individual lead exposure with relevant indices of health. Based on hunter-killed wild ducks in Argentina, we measured spleen mass, body condition, examined bone marrow smears, and determined Ca and P in bone tissue. In free-ranging live-trapped ducks we determined basic hematology and aminolevulinic acid dehydratase activity. Using multivariate analyses, we found that, when controlling for the potential confounding effect of site type, year, duck species, body mass and age, lead levels in the liver were negatively associated with body condition and spleen mass. Spleen mass was also lower in ducks with higher lead levels in their bones. In live ducks, high blood lead levels were associated with low packed cell volume and red cell morphologic abnormalities. These findings suggest that, despite the lack of recorded lead-induced mortality in the region, lead exposure results in less conspicuous but still significant impacts on the health of ducks, which could have serious implications for their conservation. Moreover, this evidence further supports the need for urgently banning lead shot in the region.

    To provide baseline findings regarding Australians' trust in federal, state and local government. A computer-assisted telephone interviewing (CATI) survey was administrated during October to December 2009 to a random sample (n=1109) across Australia (response rate 41.2%). Binary logistic regression analyses were carried out by means of SPSS. Age, household size, household income, IRSD and ARIA were found to be significant indicators for trust in federal, state and local government. Trust in state government is lower for older respondents and respondents living in inner and outer regional areas. Trust in local council is lower in respondents living in inner regional areas, respondents living in disadvantaged areas, and respondents in the income bracket of $60001 to $100000. Trust in federal government is lower for older respondents and respondents living in disadvantaged areas. Of note is diminished trust in government among older, regional and lower income ($30001-$60000) respondents. Trust in all levels of government was found to be the lowest in population groups that are identified by empirical research and media to have the poorest access to government services. As a consequence, improved access to services for these populations may increase trust in health policy. Increased trust in health governance may in turn, ensure effective dissemination and implementation of health policies and that existing inequities are not perpetuated through distrust of health information and policy initiatives.

    Full Text Available Introduction: Empirical information provided by health care professionals acting in the first line of care report a constant increase in the number of civil construction workers that present painful acute conditions, in most cases associated with the existence of urinary tract calculi. Aims: Evaluating the prevalence of urinary lithiasis in civil construction workers, as a means to identify indicators for the management of health and personnel. Methods: Observational study based on directed questionnaire. Results: From the 94 participants, 18 (19% were lithiasic, mostly due to overweight and reduced fluid intake. Conclusion: The observed prevalence appeared to be two times greater than that of the general population. Thus, prevention for such condition gains relevance, in order to avoid discomfort for the worker, and also reduce costs due to absenteeism, improving productivity, benefiting the workers by performance and creating the perspective of an improved quality of life.

    This work questions the premise that the nutritional status of children under six years of age is a reliable indicator of family health. To do so, a research strategy based in case studies was carried out, following a qualitative design (participant observation and semistructured interviews using intentional sampling) and framed within the interpretivist paradigm. The anthropometric measurements of 20 children under six years of age attending the local Child Care Center in Villa La Tela, Córdoba were evaluated. Nutritional status was understood as an object that includes socially determined biological processes, and was therefore posited analytically as a cross between statistical data and its social determination. As a statistic, child nutritional status is merely descriptive; to assist in the understanding of its social determination, it must be placed in dialectical relationship with the spheres of sociability proposed to analyze the reproduction of health problems.

    Introduction Women and children account for a disproportionate morbidity burden among conflict-affected populations, and yet they are not included in global accountability frameworks for women’s and children’s health. We use Countdown to 2015 (Millennium Development Goals) health indicators to provide an up-to-date review and analysis of the best available data on Syrian refugees in Jordan, Lebanon and Turkey and internally displaced within Syria and explore data challenges in this conflict setting. Methods We searched Medline, PubMed, Scopus, Popline and Index Medicus for WHO Eastern Mediterranean Region Office and relevant development/humanitarian databases in all languages from January 2011 until December 2015. We met in person or emailed relevant key stakeholders in Lebanon, Jordan, Syria and Turkey to obtain any unpublished or missing data. We convened a meeting of experts working with these populations to discuss the results. Results The following trends were found based on available data for these populations as compared with preconflict Syria. Birth registration in Syria and in host neighbouring countries decreased and was very low in Lebanon. In Syria, the infant mortality rate and under-five mortality rate increased, and coverage of antenatal care (one visit with a skilled attendant), skilled birth attendance and vaccination (except for DTP3 vaccine) declined. The number of Syrian refugee women attending more than four antenatal care visits was low in Lebanon and in non-camp settings in Jordan. Few data were available on these indicators among the internally displaced. In conflict settings such as that of Syria, coverage rates of interventions are often unknown or difficult to ascertain because of measurement challenges in accessing conflict-affected populations or to the inability to determine relevant denominators in this dynamic setting. Conclusion Research, monitoring and evaluation in humanitarian settings could better inform public health

    Full Text Available Abstract Accumulating evidence suggests that, independent of physical activity levels, sedentary behaviours are associated with increased risk of cardio-metabolic disease, all-cause mortality, and a variety of physiological and psychological problems. Therefore, the purpose of this systematic review is to determine the relationship between sedentary behaviour and health indicators in school-aged children and youth aged 5-17 years. Online databases (MEDLINE, EMBASE and PsycINFO, personal libraries and government documents were searched for relevant studies examining time spent engaging in sedentary behaviours and six specific health indicators (body composition, fitness, metabolic syndrome and cardiovascular disease, self-esteem, pro-social behaviour and academic achievement. 232 studies including 983,840 participants met inclusion criteria and were included in the review. Television (TV watching was the most common measure of sedentary behaviour and body composition was the most common outcome measure. Qualitative analysis of all studies revealed a dose-response relation between increased sedentary behaviour and unfavourable health outcomes. Watching TV for more than 2 hours per day was associated with unfavourable body composition, decreased fitness, lowered scores for self-esteem and pro-social behaviour and decreased academic achievement. Meta-analysis was completed for randomized controlled studies that aimed to reduce sedentary time and reported change in body mass index (BMI as their primary outcome. In this regard, a meta-analysis revealed an overall significant effect of -0.81 (95% CI of -1.44 to -0.17, p = 0.01 indicating an overall decrease in mean BMI associated with the interventions. There is a large body of evidence from all study designs which suggests that decreasing any type of sedentary time is associated with lower health risk in youth aged 5-17 years. In particular, the evidence suggests that daily TV viewing in excess of 2

    Two common methods used to measure indicators for health programme monitoring and evaluation are the demographic and health surveys (DHS) and lot quality assurance sampling (LQAS); each one has different strengths. We report on both methods when utilised in comparable situations. We compared 24 indicators in south-west Uganda, where data for prevalence estimations were collected independently for the two methods in 2011 (LQAS: n = 8876; DHS: n = 1200). Data were stratified (e.g. gender and age) resulting in 37 comparisons. We used a two-sample two-sided Z-test of proportions to compare both methods. The average difference between LQAS and DHS for 37 estimates was 0.062 (SD = 0.093; median = 0.039). The average difference among the 21 failures to reject equality of proportions was 0.010 (SD = 0.041; median = 0.009); among the 16 rejections, it was 0.130 (SD = 0.010, median = 0.118). Seven of the 16 rejections exhibited absolute differences of 0.10 and 0.20 (mean = 0.261, SD = 0.083). There is 75.7% agreement across the two surveys. Both methods yield regional results, but only LQAS provides information at less granular levels (e.g. the district level) where managerial action is taken. The cost advantage and localisation make LQAS feasible to conduct more frequently, and provides the possibility for real-time health outcomes monitoring. © 2015 The Authors.

    Full Text Available Abstract Background Malaria continues to be a global public health challenge, particularly in developing countries. Delivery of prompt and effective diagnosis and treatment of malaria cases, detection of malaria epidemics within one week of onset and control them in less than a month, regular disease monitoring and operational classification of malaria are among the major responsibilities of the national malaria programme. The study was conducted to determine these indicators at the different level of primary health care facilities in malaria-affected provinces of Iran Methods In this survey, data was collected from 223 health facilities including health centres, malaria posts, health houses and hospitals as well as the profile of all 5, 836 recorded malaria cases in these facilities during the year preceding the survey. Descriptive statistics (i.e. frequencies, percentages were used to summarize the results and Chi square test was used to analyse data. Results All but one percent of uncomplicated cases took appropriate and correctly-dosed of anti-malarial drugs in accordance to the national treatment guideline. A larger proportion of patients [85.8%; 95% CI: 84.8 - 86.8] were also given complete treatment including anti-relapse course, in line with national guidelines. About one third [35.0%; 95% CI: 33.6 - 36.4] of uncomplicated malaria cases were treated more than 48 hours after first symptoms onset. Correspondingly, half of severe malaria cases took recommended anti-malarial drugs for severe or complicated disease more than 48 hours of onset of first symptoms. The latter cases had given regular anti-malarial drugs promptly. The majority of malaria epidemics [97%; 95% CI: 90.6 - 100] in study areas were detected within one week of onset, but only half of epidemics were controlled within four weeks of detection. Just half of target districts had at least one health facility/emergency site with adequate supply and equipment stocks. Nevertheless

    To determine what relation, if any, exists between mortality patterns, indicators of deprivation, general lifestyle and social attitudes, as exemplified by general election voting pattern, in the Republic of Ireland. A relation has been demonstrated previously between voting and mortality patterns in the United Kingdom. Cross sectional ecological study using three data sources. Standardised mortality ratios (SMR) were based on mortality rates at county level and 1996 census data from the Central Statistics Office, 1997 general election first preference voting data in all 41 constituencies were aggregated to county level. Selected reported measures of health status, lifestyle and social circumstances are from the first ever National survey on lifestyles, attitudes and nutrition (SLAN). This study comprised adults over 18 years sampled by post using the electoral register from 273 representative district electoral divisions. Univariate inter-relations were examined at individual level for the dataset as a whole, adjusting for age and at aggregated level for 26 county borough areas, which included the two largest cities and for 22 county areas, which afforded correlation with voting pattern, using the method of Pearson's correlation coefficient. 1,806,932 votes were cast nationally at the 1997 general election, representing a voter turnout of 65.92 %. There was an overall response rate of 62% to SLAN comprising 6539 adults (47% male). The demographic pattern of survey respondents was consistent with that of the general population over 18 years. At individual level there was a large number of highly significant inter-relations between indicators of deprivation, various measures of self rated health status and lifestyle factors. Aggregated at 26 county level percentage unemployed (r=0.408, p=0.038), and level of education (r=0.475, p=0.014) related significantly to SMR and inversely to both fruit and vegetable consumption (r= -0.672, p=0.001) and excess alcohol

    Objective. To assess and improve student adherence to hand hygiene indications using radio frequency identification (RFID) enabled hand hygiene stations and performance report cards. Design. Students volunteered to wear RFID-enabled hospital employee nametags to monitor their adherence to hand-hygiene indications. After training in World Health Organization (WHO) hand hygiene methods and indications, student were instructed to treat the classroom as a patient care area. Report cards illustrating individual performance were distributed via e-mail to students at the middle and end of each 5-day observation period. Students were eligible for individual and team prizes consisting of Starbucks gift cards in $5 increments. Assessment. A hand hygiene station with an RFID reader and dispensing sensor recorded the nametag nearest to the station at the time of use. Mean frequency of use per student was 5.41 (range: 2-10). Distance between the student's seat and the dispenser was the only variable significantly associated with adherence. Student satisfaction with the system was assessed by a self-administered survey at the end of the study. Most students reported that the system increased their motivation to perform hand hygiene as indicated. Conclusion. The RFID-enabled hand hygiene system and benchmarking reports with performance incentives was feasible, reliable, and affordable. Future studies should record video to monitor adherence to the WHO 8-step technique.

    High rates of obesity and chronic disease make establishment of effective indicators of risk for chronic disease important. The objective was to examine adequacy of anthropometric cut-off points as indicators of risk for chronic disease among Samoan women in Hawaii. A cross-sectional survey of 55 Samoan women 18 to 28 years of age that included blood lipids, cholesterol, and glucose (including after a 2-hour oral glucose test); anthropometry (weight, height, waist circumference); and DXA of body composition. Using the Centers for Disease Control and Prevention (CDC)/World Health Organization (WHO) cut-off points for BMI, 22% of women were overweight and 58% were obese. Cholesterol, lipid, and glucose values were all linearly related to DXA body fat, BMI, and waist circumference. BMI and waist circumference at WHO/NIH cut-off points predicted levels of blood lipids and glucose that indicate elevated risk for disease. WHO/NIH cut-off points for BMI and waist circumference reflect risk indicators of chronic disease among young Samoan women in Hawaii.

    The emergence of multidrug-resistant pathogens and the prevalence of biofilm-related infections have generated a demand for alternative anti-microbial therapies. Metals have not been explored in adequate detail for their capacity to combat infectious disease. Metal compounds can now be found in textiles, medical devices and disinfectants-yet, we know little about their efficacy against specific pathogens. To help fill this knowledge gap, we report on the anti-microbial and antibiofilm activity of seven metals: silver, copper, titanium, gallium, nickel, aluminum and zinc against three bacterial strains, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. To evaluate the capacity of metal ions to prevent the growth of, and eradicate biofilms and planktonic cells, bacterial cultures were inoculated in the Calgary Biofilm Device (minimal biofilm eradication concentration) in the presence of the metal salts. Copper, gallium and titanium were capable of preventing planktonic and biofilm growth, and eradicating established biofilms of all tested strains. Further, we observed that the efficacies of the other tested metal salts displayed variable efficacy against the tested strains. Further, contrary to the enhanced resistance anticipated from bacterial biofilms, particular metal salts were observed to be more effective against biofilm communities versus planktonic cells. In this study, we have demonstrated that the identity of the bacterial strain must be considered before treatment with a particular metal ion. Consequent to the use of metal ions as anti-microbial agents to fight multidrug-resistant and biofilm-related infections increases, we must aim for more selective deployment in a given infectious setting.

    We review evidence for and against the use of erythrocyte indicators of health status and condition, parasite infection level and physiological stress in free-living vertebrates. The use of indicators that are measured directly from the blood, such as haemoglobin concentration, haematocrit and erythrocyte sedimentation rate, and parameters that are calculated from multiple measured metrics, such as mean cell volume, mean cell haemoglobin content or mean cell haemoglobin concentration is evaluated. The evidence for or against the use of any given metric is equivocal when the relevant research is considered in total, although there is sometimes strong support for using a particular metric in a particular taxon. Possibly the usefulness of these metrics is taxon, environment or condition specific. Alternatively, in an uncontrolled environment where multiple factors are influencing a metric, its response to environmental change will sometimes, but not always, be predictable. We suggest that (i) researchers should validate a metricfres utility before use, (ii) multiple metrics should be used to construct an overall erythrocyte profile for an individual or population, (iii) there is a need for researchers to compile reference ranges for free-living species, and (iv) some metrics which are useful under controlled, clinical conditions may not have the same utility or applicability for free-living vertebrates. Erythrocyte metrics provide useful information about health and condition that can be meaningfully interpreted in free-living vertebrates, but their use requires careful forethought about confounding factors. © 2015 Cambridge Philosophical Society.

    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

    Full Text Available Introduction: There is little data on the association of metabolic syndrome and health status in Serbian men, so our intention was to investigate the prevalence of the metabolic syndrome in men with no history of diabetes or cardiovascular disease in New Belgrade, Serbia; to determine which of the anthropometric parameters (body mass index—BMI and waist circumference—WC is best for the evaluation of health risks in primary care, especially the risk factors for metabolic syndrome. Research Methods and Procedures: The study involved 132 healthy men ages 44.73 ± 9.37 years. Anthropometric values were measured in all the patients. Blood pressure, blood biochemistry (high-density lipoprotein- cholesterol, low-density lipoprotein-cholesterol, triglycerides, blood glucose and analysis of their medical records were also done. Analysis of consistency has been used in testing hypothesis. Results: The sample consisted of 132 patients with mean age 44.73 ± 9.37 years. The prevalence of the metabolic syndrome was 44.7%. Analysis of consistence showed differences in the combined predictive ability of anthropometric indicators and other factors of MetS. Conclusions: BMI andWCare the simple measures of adiposity most strongly associated with metabolic abnormalities. Our findings suggest that WC can not be used as a complementary measurement to identify health risks in any group of men

    Studies concerning the more appropriate criteria for evaluating oral health in relation to nutrition in the elderly vary greatly. There is a need to identify the most relevant criteria for classifying dental indicators of mastication in nutritional studies, so these indicators may be considered for epidemiological and clinical purposes. The aim of this study was to explore the associations between nutritional deficit and measures of oral health in a group of elderly. A convenience sample of independent elderly aged 65 years or more attending two primary care clinics in Beirut, Lebanon was selected. Data were collected from a questionnaire including the Mini-Nutritional Assessment (MNA), Geriatric Oral Health Assessment Index (GOHAI) and questions about perception of xerostomia and chewing problems. The oral examinations recorded decayed, missing and filled teeth (DMFT), the prosthetic status and the number of functional units (FU). The sample was composed of 121 women (mean age: 71.59 ± 5.97 years) and 80 men (mean age: 72.74 ± 6.98 years). They were allocated to two groups: 85 participants suffering from malnutrition (MNA score nutritional status (MNA score ≥ 24). Parameters that explain MNA variations were perception of xerostomia (OR = 3.49, 95% CI [1.66-7.34]), number of FU (OR = 2.79, 95% CI [1.49; 5.22]), and GOHAI score (OR = 2.905, 95% CI [1.40; 6.00]). Further studies exploring factors affecting nutrition in the elderly should take into consideration perception of xerostomia, number of FUs and GOHAI score. Copyright © 2013.

    This preliminary research was conducted to evaluate the alpine stream health by using water quality as an indicator in Khunjerab National park of the Karakoram ranges located in Pak-China boarder Pakistan having altitude of 3660 m. This study investigated the stream health in the context of the presence or absence of sensitive species, their diversity, and their taxa richness. The water and macroinvertebrate samples were collected from 17 different locations from upstream and downstream of the river by using random sampling method. Macroinvertebrate samples were obtained using kick net (500-μm mesh size) and hand-picking method (NYSDEC). A total of 710 counts including 41 families of macroinvertebrates were recorded comprising of 7 orders including: Ephemeroptera (46%) being the most dominant group, Plecoptera (33%), Trichoptera (5%), Chironomidae (Diptera) (14%), Heteroptera (1%), and Coleoptera (1%). Ephemeroptera, Trichoptera, and Plecoptera (EPT) were found in abundance at the main source, Qarchanai, Dhee, and Tourqeen Nullah, as compared to the other locations of the stream. The most dominant macroinvertebrate was Ephemeroptera whose relative abundance is Pi = 0.49 by using the Shannon index. However, different statistical tools, including principal component analysis (PCA), cluster analysis (CA), ANOVA, and linear regression model, show a strong correlation between water quality and macroinvertebrates. The overall results of the biological indicators showed better ecological health at downstream compared to upstream. This study will provide basic information and understanding about the macroinvertebrates for future researchers, and the data will be helpful for upcoming research programs on alpine streams for the discovery and occurrences of macroinvertebrates and associated fauna.

    Previous studies on the relationship between bone health and metabolic syndrome (MS) have revealed heterogeneous results. There are limited studies employing bone quantitative ultrasonometry in evaluating this relationship. This study aimed to determine the relationship between MS and bone health in a group of Malaysian middle-aged and elderly men using bone quantitative ultrasonometry. This cross-sectional study recruited 309 free living Chinese and Malay men aged 40 years and above residing in Klang Valley, Malaysia. Their demographic and anthropometric data were collected. Their calcaneal speed of sound (SOS) was measured using a CM-200 bone ultrasonometer. Their blood was collected for the evaluation of lipid profile, total testosterone and sex hormone-binding globulin. The joint interim MS definition was used for the classification of subjects. Multiple linear regression analysis was used to assess the association between SOS and indicators of MS and the presence of MS, with suitable adjustment for confounders. There was no significant difference in SOS value between MS and non-MS subjects (p > 0.05). The SOS values among subjects with different MS scores did not differ significantly (p > 0.05). There were no significant associations between SOS values and indicators of MS or the presence of MS (p > 0.05). The relationship between bone health and MS is not significant in Malaysian middle-aged and elderly men. A longitudinal study should be conducted to evaluate the association between bone loss and MS to confirm this finding.

    Gut microbial dysbiosis and alteration of microbial metabolites in Parkinson's disease (PD) have been increasingly reported. Dysbiosis in the composition and abundance of gut microbiota can affect both the enteric nervous system and the central nervous system (CNS), indicating the existence of a microbiota-gut-brain axis and thereby causing CNS diseases. Disturbance of the microbiota-gut-brain axis has been linked to specific microbial products that are related to gut inflammation and neuroinflammation. Future directions should therefore focus on the exploration of specific gut microbes or microbial metabolites that contribute to the development of PD. Microbiota-targeted interventions, such as antibiotics, probiotics and fecal microbiota transplantation, have been shown to favorably affect host health. In this review, recent findings regarding alterations and the role of gut microbiota and microbial metabolites in PD are summarized, and potential molecular mechanisms and microbiota-targeted interventions in PD are discussed.

    It is necessary to use health indicators describing the conditions of all individuals in a population, not just of those who have a disease or die. To introduce a method to collect population indicators of psychomotor development in children younger than 6 years old and show its results. Data were obtained from a cross-sectional assessment regarding compliance with 13 developmental milestones (selected from the national reference) conducted in 5465 children using five surveys administered by the Matanza-Riachuelo River Basin Authority in areas of this basin where a high proportion of families with unmet basic needs live. For each survey, a logistic regression analysis was used to estimate the median age at attainment of the 13 developmental milestones. A linear regression model between the estimated age at attainment of the 13 milestones was adjusted for each survey based on the corresponding age at attainment of the national reference. Based on this model, three indicators were defined: overall developmental quotient, developmental quotient at 4 years old, and developmental trend. Results from the five surveys ranged between 0.74 and 0.85, 0.88 and 0.81, and -0.15 and -0.26 for the overall developmental quotient, developmental quotient at 4 years old, and developmental trend, respectively. A distinct developmental delay and an increasing trend in delay with age were observed. Indicators are easily interpreted and related to social indicators (unmet basic needs, etc.). Collecting the information necessary to make estimations takes little time and can be applied to population groups, but not on an individual level. Sociedad Argentina de Pediatría.

    Few studies link organizational variables and outcomes to quality indicators. This approach would expose operant mechanisms by which work environment characteristics and organizational outcomes affect clinical effectiveness, safety, and quality indicators. What are the predominant psychosocial variables in the explanation of organizational outcomes and quality indicators (in this case, medication errors and length of stay)? The primary objective of this study was to link the fields of evidence-based practice to the field of decision making, by providing an effective model of intervention to improve safety and quality. The study involved healthcare workers (n = 243) from 13 different care units of a university affiliated health center in Canada. Data regarding the psychosocial work environment (10 work climate scales, effort/reward imbalance, and social support) was linked to organizational outcomes (absenteeism, turnover, overtime), to the nurse/patient ratio and quality indicators (medication errors and length of stay) using path analyses. The models produced in this study revealed a contribution of some psychosocial factors to quality indicators, through an indirect effect of personnel- or human resources-related variables, more precisely: turnover, absenteeism, overtime, and nurse/patient ratio. Four perceptions of work environment appear to play an important part in the indirect effect on both medication errors and length of stay: apparent social support from supervisors, appreciation of the workload demands, pride in being part of one's work team, and effort/reward balance. This study reveals the importance of employee perceptions of the work environment as an indirect predictor of quality of care. Working to improve these perceptions is a good investment for loyalty and attendance. In general, better personnel conditions lead to fewer medication errors and shorter length of stay. © Sigma Theta Tau International.

  16. A holistic model for the selection of environmental assessment indicators to assess the impact of industrialization on indigenous health.

    2011-01-01

    Mainstream environmental assessment (EA) methodologies often inadequately address health, social and cultural impacts of concern for Canadian indigenous communities affected by industrialization. Our objective is to present a holistic, culturally-appropriate framework for the selection of indigenous health indicators for baseline health assessment, impact prediction, or monitoring of impacts over time. We used a critical population health approach to explore the determinants of health and health inequities in indigenous communities and conceptualize the pathways by which industrialization affects these determinants. We integrated and extended key elements from three indigenous health frameworks into a new holistic model for the selection of indigenous EA indicators. The holistic model conceptualizes individual and community determinants of health within external social, economic and political contexts and thus provides a comprehensive framework for selecting indicators of indigenous health. Indigenous health is the product of interactions among multiple determinants of health and contexts. Potential applications are discussed using case study examples involving indigenous communities affected by industrialization. Industrialization can worsen indigenous health inequities by perpetuating the health, social and cultural impacts of historic environmental dispossession. To mitigate impacts, EA should explicitly recognize linkages between environmental dispossession and the determinants of health and health inequities and meaningfully involve indigenous communities in the process.

    Although the issue of monitoring appropriateness of tumour markers (TMs) request in outpatients remains crucial, proper indicators are still demanding. The present study developed and explored indicators of inappropriate TM ordering in outpatients through the data mining of electronic health records (EHRs). Carcinoembryonic antigen (CEA), alfa-fetoprotein (AFP), carbohydrate antigen (CA)125, CA15.3, CA19.9, and prostate-specific antigen (PSA) ordered in outpatients during a year were examined by mining EHRs of a Local Health Authority in Italy. Evidence-based criteria were used to develop performance indicators. Demographic and clinical information associated with TM orders were examined. A total of 80 813 TMs were ordered in 52 536 outpatients (1.54 markers/patient). Indicators related to disease codes, gender, age, and TM repetitions were developed, and their application showed that (1) CA15.3 and CEA are prevalently requested in patients with cancer (79.2% and 65.6%) whereas the other TMs are largely requested also in patients without cancer; (2) requests of PSA in women and of CA125 or CA15.3 in men are negligible; (3) although requests in people older than 80 years are relevant (16.4% of total), the highest rate of request of all markers occurs in patients aged 40 to 79 years; (4) CA15.3 and CEA are mainly requested in cancer cases between 50 and 79 years and AFP, CA19.9, and CA125 in those between 60 and 69 years; (5) associated with cancer code for all age intervals; and (6) multiple repetitions of AFP, CA125, CA15.3, CA19.9, and CEA are prevalent in cancer patients or benign diseases to which TMs are appropriate, whereas PSA repetitions occur mainly in patients without cancer. The developed indicators resulted suitable to monitor TM overordering in outpatients through the mining of EHRs. The present study is a first approach towards the use of big-data mining for TM appropriateness evaluation purposes. © 2017 John Wiley & Sons, Ltd.

    Turkish health reforms began in 2003 and brought some significant changes in primary care services. Few studies in Turkey compare the shift from health centres (HC) to family physicians (FP) approach, which was initiated by reforms. This study compares health status indicators during the HC period before reforms (2003-2007) and the FP period after reforms (2008-2012) in Turkey. This study encompasses time series data consisting of the results of a 10-year assessment (2003-2012) in Manisa district. All the data were obtained electronically and by month. The intersection points of the regression curves of these two periods and the beta coefficients were compared using segmented linear regression analysis. The mean number of follow-up per person/year during the HC period in infants (10.5), pregnant women (6.6) and women (1.8) was significantly higher than the mean number of follow-up during the FP period in infants (6.7), pregnant women (5.6) and women (0.9). Rates of BCG and measles vaccinations were significantly higher during the FP period; however, rates of HBV and DPT were same. The mean number of outpatient services per person/year during the FP period (3.3) was significantly higher than HC period (2.8). Within non-communicable diseases, no difference was detected for hypertension prevalence. Within communicable diseases, there was no difference for rabies suspected bites but acute haemorrhagic gastroenteritis significantly decreased. The infant mortality rate and under five-year child mortality rate significantly increased during the FP period. Primary care services should be reorganized and integrated with public health services.

    Bioarchaeological findings have linked defective enamel formation in preadulthood with adult mortality. We investigated how defective enamel formation in infancy and childhood is associated with risk factors for adult morbidity and mortality in adolescents. This cohort study of 349 Amerindian adolescents (10-17 years of age) related extent of enamel defects on the central maxillary incisors (none, less than 1/3, 1/3 to 2/3, more than 2/3) to adolescent anthropometrics (height, weight) and biomarkers (hemoglobin, glycated hemoglobin, white blood cell count, and blood pressure). Risk differences and 95% confidence intervals were estimated using multiple linear regression. Enamel defects and stunted growth were compared in their ability to predict adolescent health indicators using log-binomial regression and receiver operating characteristics (ROCs). Greater extent of defective enamel formation on the tooth surface was associated with shorter height (-1.35 cm, 95% CI: -2.17, -0.53), lower weight (-0.98 kg, 95% CI: -1.70, -0.26), lower hemoglobin (-0.36 g/dL, 95% CI: -0.59, -0.13), lower glycated hemoglobin (-0.04 %A 1c , 95% CI: -0.08, -0.00008), and higher white blood cell count (0.74 10 9 /L, 95% CI: 0.35, 1.14) in adolescence. Extent of enamel defects and stunted growth independently performed similarly as risk factors for adverse adolescent outcomes, including anemia, prediabetes/type II diabetes, elevated WBC count, prehypertension/hypertension, and metabolic health. Defective enamel formation in infancy and childhood predicted adolescent health outcomes and may be primarily associated with infection. Extent of enamel defects and stunted growth may be equally predictive of adverse adolescent health outcomes. © 2018 Wiley Periodicals, Inc.

    The present study was aimed at analysing how social sports projects are evaluated so as to draw up and develop indicators of success regarding social programmes' efficacy and effectiveness. This was a descriptive survey. The sample consisted of 51 participants, male (n=29) and female (n=22), from the Nova Descoberta project whose ages ranged from 8 to 17. Data was obtained from a semi-directed survey having open items covering 10 topics; it was carried out with children and adolescents over a 2-year period (2007-2008). Documental data was also obtained from schools which had agreed to cooperate with the project. There were no statistically significant differences (pperformance of survey group participants and those who had not joined the project in terms of scholastic performance during 2007. A significant difference (psports projects. The manifestation of other characteristics in the environment could have interfered with participation and involvement in physical activity and, consequently, with the children and adolescents' health and quality of life. It was found that school work performance indicators could be taken together with other indicators, such as development of various abilities, participation in other activities, activity motivation, behaviour and attitudes at home and at school, for evaluating social projects.

  1. Satellite Lithium-Ion Battery Remaining Cycle Life Prediction with Novel Indirect Health Indicator Extraction

    Full Text Available Prognostics and remaining useful life (RUL estimation for lithium-ion batteries play an important role in intelligent battery management systems (BMS. The capacity is often used as the fade indicator for estimating the remaining cycle life of a lithium-ion battery. For spacecraft requiring high reliability and long lifetime, in-orbit RUL estimation and reliability verification on ground should be carefully addressed. However, it is quite challenging to monitor and estimate the capacity of a lithium-ion battery on-line in satellite applications. In this work, a novel health indicator (HI is extracted from the operating parameters of a lithium-ion battery to quantify battery degradation. Moreover, the Grey Correlation Analysis (GCA is utilized to evaluate the similarities between the extracted HI and the battery’s capacity. The result illustrates the effectiveness of using this new HI for fading indication. Furthermore, we propose an optimized ensemble monotonic echo state networks (En_MONESN algorithm, in which the monotonic constraint is introduced to improve the adaptivity of degradation trend estimation, and ensemble learning is integrated to achieve high stability and precision of RUL prediction. Experiments with actual testing data show the efficiency of our proposed method in RUL estimation and degradation modeling for the satellite lithium-ion battery application.

    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

    When ingested in sufficient numbers, probiotics are expected to confer one or more proven health benefits on the consumer. Theoretically, the effectiveness of a probiotic food product is the sum of its microbial quality and its functional potential. Whereas the latter may vary much with the body (target) site, delivery mode, human target population, and health benefit envisaged microbial assessment of the probiotic product quality is more straightforward. The range of stakeholders that need to be informed on probiotic quality assessments is extremely broad, including academics, food and biotherapeutic industries, healthcare professionals, competent authorities, consumers, and professional press. In view of the rapidly expanding knowledge on this subject, the Belgian Superior Health Council installed Working Group “8651 Probiotics” to review the state of knowledge regarding the methodologies that make it possible to characterize strains and products with purported probiotic activity. This advisory report covers three main steps in the microbial quality assessment process, i.e. (i) correct species identification and strain-specific typing of bacterial and yeast strains used in probiotic applications, (ii) safety assessment of probiotic strains used for human consumption, and (iii) quality of the final probiotic product in terms of its microbial composition, concentration, stability, authenticity, and labeling.

    Aderita Sena

    Full Text Available Brazil has a large semiarid region, which covers part of 9 states, over 20% of the 5565 municipalities in the country and at 22.5 million persons, 12% of the country's population. This region experiences recurrent and extended droughts and is characterized by low economic development, scarcity of natural resources including water, and difficult agricultural and livestock production. Local governments and communities need easily obtainable tools to aid their decision making process in managing risks associated with drought.To inform decision-making at the level of municipalities, we investigated factors contributing to the health risks of drought. We used education and poverty indicators to measure vulnerability, number of drought damage evaluations and historical drought occurrences as indicators of hazard, and access to water as an indicator of exposure, to derive a drought disaster risk index.Indicators such as access to piped water, illiteracy and poverty show marked differences in most states and, in nearly all states, the living conditions of communities in the semiarid region are worse than in the rest of each state. There are municipalities at high drought disaster risk in every state and there are a larger number of municipalities at higher risks from the center to the north of the semiarid region.Understanding local hazards, exposures and vulnerabilities provides the means to understand local communities' risks and develop interventions to reduce them. In addition, communities in these regions need to be empowered to add their traditional knowledge to scientific tools, and to identify the actions most relevant to their needs and realities.

    This report presents a set of bibliometric indicators and statistics which explain the high level of production of articles on research in public and collective health in Brazil which are published in the main nationally edited journals in the field. The predominance of publications in the Portuguese language by Brazilian authors results in a lower impact in terms of citations received as measured by the bibliometric indexes Scimago/Scopus and JCR/WoS. These bibliometric indexes are used to measure the production and performance of research and journals. Nevertheless, the performance of these same journals stands out in SciELO, and is competitive internationally in the broader context of Google Scholar Metrics. The challenge faced by journals in Brazil is developing and applying editorial policies for the valuation of research with a national focus, and its internationalization.

    Full Text Available A cross-national study of young adult sexual minorities was conducted in order to explore the associations between sexual orientation and measures of depression, suicidality, and substance use. Two nationally representative data sets were explored from the United States (N = 14,335 and Norway (N = 2423. Results indicated that sexual minorities experienced multiple health disparities (depression, suicidality, and substance use compared to their heterosexual counterparts. We found similar patterns of depression, suicidality, and substance use for sexual minorities in both the United States and Norway. The highest odds of substance use were among heterosexual-identified Norwegian youth who reported same-sex sexual activity, and the highest odds of suicidality were found for bisexual young adults in Norway. These findings have implications for how we consider culture and social policy as barriers and/or opportunities for sexual minorities.

    Full Text Available Abstract Background The weakening of the cardiovascular system associated with aging could be countered by increasing levels of physical activity and functional fitness. However, inconsistent findings have been found, and the variety of characteristics of exercise used in previous studies may partly explain that inconsistent results. Objective To investigate the training effect of sixteen weeks of moderate intensity, progressive aerobic and strength-based training on metabolic health of older women and men. Methods Sixty three sedentary individuals (mean (SD age 76 (8 years were randomly assigned to control (n = 31 or exercising (n = 32 groups. The training group was separated to aerobic (n = 18 or strength-based (n = 14. Training took place three times a week. Subjects agreed not to change their diet or lifestyle over the experimental period. Results Exercising group attained after treatment significant differences on body weight, waist circumference, body mass index, diastolic blood pressure, triglycerides, total cholesterol, HDL-cholesterol, LDL-cholesterol, total cholesterol/HDL-cholesterol relationship, high sensitivity C-reactive protein, and 6-minute walk distance. The control group only had significant differences on waist circumference. Conclusion The training programs produced significant benefits on metabolic health indicators of sedentary older women and men.

    Full Text Available Introduction: Many organizations, especially, service organizations, relative to their goals and mission, have a special view towards quality phenomena and its management and are turning to approaches such as TQM to help manage their business. This study examined the TQM indicators gap in Isfahan Khorshid hospital. As fuzzy set theory is better than the logical theory for estimating the linguistic factors, this paper tries to apply fuzzy approach to quality management in hospitals and analyzes the gap between personnel expectations and perception. Methods: This paper analyzes medical total quality management in a case (Internal Section of Khorshid Hospital, based on gap analysis model and fuzzy logic. A questionnaire was therefore applied to measure expectations and perceptions of hospital personnel. Results: This study results show that on the whole, there is a significant difference between TQM expectations and perceptions among K`horshid hospital personnel. Conclusions: Spurred by impressive results in other industries, this compelling and logical approach has begun to penetrate the thinking of health care accrediting agencies, business coalitions, private foundations and leading health care organizations. However, before making a commitment to TQM, hospital decision makers should thoroughly understand what it is they are committing to, and solve the main barriers such as the conflict between hospital management philosophies and TQM philosophies.

    Full Text Available Abstract Background The recent Ebola Virus Disease (EVD epidemic that hit some countries in West Africa underscores the need to train front line high-risk health workers on disease prevention skills. Although Ghana did not record (and is yet to any case, and several health workers have received numerous training schemes, there is no record of any study that assessed preparedness of healthcare workers (HCWS regarding EVD and any emergency prone disease in Ghana. We therefore conducted a hospital based cross sectional study involving 101 HCWs from two facilities in Kumasi, Ghana to assess the level of preparedness of HCWs to respond to any possible EVD. Methods We administered a face-to-face questionnaire using an adapted WHO (2015 and CDC (2014 Checklist for Ebola Preparedness and assessed overall knowledge gaps, and preparedness of the Ghanaian HCWs in selected health facilities of the Ashanti Region of Ghana from October to December 2015. Results A total 92 (91.09% HCWs indicated they were not adequately trained to handle an EVD suspected case. Only 25.74% (n = 26 considered their facilities sufficiently equipped to handle and manage EVD patients. When asked which disinfectant to use after attending to and caring for a suspected patient with EVD, only 8.91% (n = 9 could correctly identify the right disinfectant (χ2 = 28.52, p = 0.001. Conclusion Our study demonstrates poor knowledge and ill preparedness and unwillingness of many HCWs to attend to EVD. Beyond knowledge acquisition, there is the need for more training from time to time to fully prepare HCWs to handle any possible EVD case.

    This study aimed to identify participant characteristics associated with volunteering among older adults. Based on data from the 2008 Aging Texas Well (ATW) Indicators Survey, we examined the degree to which demographic factors, health status, spiritual participation, and community involvement are associated with volunteering among adults aged 60 years or older (n = 525). Rates of volunteering varied by race/ethnicity: non-Hispanic Whites (56.4%), African Americans (51.1%), and Hispanics (43.2%). Bivariate analyses showed that non-Hispanic White older adults were more likely to participate in formal volunteering activities, while their African American and Hispanic counterparts tended to participate in informal volunteering activities. Logistic regression analyses revealed that volunteering was less observed among Hispanics (OR = 0.48, 95% CI 0.29-0.78). Volunteering was more observed among those who reported providing informal care (OR=1.93, 95% CI 1.14-3.28), having very good or excellent mental health (OR = 1.90 and 2.07, 95% CI 1.09-3.32 and 1.20-3.55, respectively), having weekly or daily spiritual participation (OR = 2.15 and 2.35, 95% CI 1.28-3.63 and 1.29-4.28, respectively), perceiving community involvement very important (OR = 2.37, 95% CI 1.55-3.62), and being very satisfied with the community interaction (OR = 1.81, 95% CI 1.15-2.85). Given the positive associations of mental health, spirituality, and social engagement with volunteering among older adults, system-level efforts to increase the sense of community among older adults and recognize their roles as volunteers will be helpful in recruiting and retaining older volunteers.

  17. Endocrine check-up in adolescents and indications for referral: A guide for health care providers

    Directory of Open Access Journals (Sweden)

    Vincenzo De Sanctis

    2014-01-01

    Full Text Available The American Academy of Pediatrics recommends that young people between the ages of 11 and 21 years should be seen annually by their pediatricians, since annual checkups can be an important opportunity for health evaluation and anticipatory guidance. Parents of infants and young children are accustomed to regularly visiting a pediatrician for their child′s checkups. Unfortunately, when children reach the teen years, these annual checkups may decrease in frequency. In routine check-ups and medical office visits, particular attention should be paid to the possibility of a developmental or endocrine disorder. Early diagnosis and treatment may prevent medical complications in adulthood and foster age-appropriate development. Our purpose is to acquaint readers with the concept, based on current scientific understanding, that some endocrine disorders may be associated with a wide range of deleterious health consequences including an increased risk of hypertension and hyperlipidemia, increased risk of coronary artery disease, type 2 diabetes, significant anxiety and lack of self-esteem. Understanding the milestones and developmental stages of adolescence is essential for pediatricians and all other health providers who care for adolescents. Treating adolescents involves knowledge of a variety of medical, social and legal information; in addition, close working relationships must be established within the adolescent′s network to create an effective care system. In summary, we underline the importance of a periodic endocrine checkup in adolescents in order to identify endocrine problems early and develop an approach to treatment for those patients who need help during this time. Indications for endocrine referral for professional and other healthcare providers are also included. These lists are clearly not intended to be comprehensive, but will hopefully serve as a guide for specific clinical circumstances.

    Full Text Available Objective: This study aimed to investigate the relationship among motor performance and nutritional status in students. Methods: Attended by 27 adolescents of both sexes, aged between 11-13 years (average 11.74 ± 0.70 years from a private school in Florianópolis/SC. The motor performance was assessed using the MABC-2. For assess the nutritional status was used the BMI calculus. Results: Among 27 participants, 6 had a risk / indicative of motor difficulties and 9 had overweight. The vast majority of participants had adequate height for age. There was negative significant statistically correlation, but moderate, among BMI and total performance in the MABC-2, indicating that as higher the BMI, worse is the motor performance. Conclusion: Based on these results and the literature, it is suggested that in addition to the identification of children with overweight and motor difficulties, programs targeted physical activity and motor interventions are implemented, especially in the school environment, aiming to maintain the health conditions.

    Full Text Available The main aim of this study was to determine health benefits among women older than 55 years who participated in organized, group-based physical activity (OPA. Thirty-five women aged 65.0 ± 7.3 years volunteered for this study. The classical and nonclassical cardiovascular (CVD risk factors were measured before and after a 2-week OPA camp in a remote location and 3 months of OPA. Self-guided physical activity was analyzed 18 months after OPA. Two-week effects included significant decreases in body mass index, waist and hip circumferences, resting systolic and diastolic blood pressure (BP and resting heart rate, improved exercise capacity (EC, improved low-density lipoprotein and high-density lipoprotein (HDL-C, cholesterol, and other atherogenic lipid indices (ALI, and a reduction in 10-year estimated risk of death from CVD. Three-month effects included a further decrease in systolic BP, improvements in EC and HDL-C, and maintenance of lower levels of ALI, as well as lower CVD risk. The implementation of the OPA programme had a positive impact on somatic features, exercise capacity, biochemical indices, and risk for death from CVD. The presented programme can be regarded as an effective element of primary prevention of cardiovascular diseases among women older than 55 years.

    The aim of the study was to assess the value of different indicators of socioeconomic status for oral health research among Sri Lankan adolescents. Six indicators of socioeconomic status were assessed in terms of their relationship to 2 oral health outcomes. The sample consisted of 15-year-old students (n = 1218) selected from 48 schools in the Colombo district using a stratified cluster sampling technique. Data collection included oral examinations of students and questionnaires to both students and their parents. The correlations between the 6 indicators were low to moderate. The indicators of household material assets and parental educational status emerged as significant predictors of the 2 oral health outcomes. Therefore, it is concluded that indicators of material assets-namely, the family affluence scale and the asset index-could be used as optimal measures of socioeconomic status in oral health research among adolescents in Sri Lanka.

Among the elderly, 47.5% was aged 60 to 69 years and 48.3% was widow. They lived in homes with three generations (38.1% and had low level of education: incomplete elementary school (88.7%. The elderly women were on retirement plan (58.5%, had monthly income up to minimum wage (51.7% and belonged to socioeconomic class D (55.8%. As for the PBI, 54% of the women were dissatisfied, mainly for body mass excess (35.1%. PBI was associated to the nutritional status, i.e., an increase in the BMI category raised the proportion of dissatisfied seniors. However, PBI was not associated with socio-demographic characteristics, health indicator or physical activity level. Comparing satisfied and dissatisfied women, no differences were noted in physical activity level, age or stature

    It has long been recognised that urban form impacts on health outcomes and their determinants. There is growing interest in creating indicators of liveability to measure progress towards achieving a wide range of policy outcomes, including enhanced health and wellbeing, and reduced inequalities. This review aimed to: 1) bring together the concepts of urban 'liveability' and social determinants of health; 2) synthesise the various liveability indicators developed to date; and 3) assess their quality using a health and wellbeing lens. Between 2011 and 2013, the research team reviewed 114 international academic and policy documents, as well as reports related to urban liveability. Overall, 233 indicators were found. Of these, 61 indicators were regarded as promising, 57 indicators needed further development, and 115 indicators were not useful for our purposes. Eleven domains of liveability were identified that likely contribute to health and wellbeing through the social determinants of health. These were: crime and safety; education; employment and income; health and social services; housing; leisure and culture; local food and other goods; natural environment; public open space; transport; and social cohesion and local democracy. Many of the indicators came from Australian sources; however most remain relevant from a 'global north' perspective. Although many indicators were identified, there was inconsistency in how these domains were measured. Few have been validated to assess their association with health and wellbeing outcomes, and little information was provided for how they should be applied to guide urban policy and practice. There is a substantial opportunity to further develop these measures to create a series of robust and evidence-based liveability indices, which could be linked with existing health and wellbeing data to better inform urban planning policies within Australia and beyond.

    The objective of the present study was to evaluate the applicability of purine derivative (PD) method to Sri Lankan Zebu cattle and their crosses. In the first experiment four male Zebu cattle (LW 100 kg) were used to determine the response of PD excretion at four levels of intake (95, 80, 60 and 40% of the voluntary intake). Digestibility of dry matter and organic matter were not affected (P > 0.05) but nitrogen retention was increased with increasing levels of feed intake. The PD excretion were 1.91, 1.46, 1.21 and 0.66 mmol/kgW 0.75 /d for 95, 80, 60 and 40% of the voluntary intake levels, respectively. The proportion of allantoin in total PD was 82.6%. The excretion of creatinine was 1.05, 1.04, 0.92 and 0.84 mmol/kgW 0.75 /d, respectively. Daily output of total PD showed a positive response to the level of feed intake, while creatinine excretion was independent of dietary treatments. The correlation between PD excretion and digestible organic matter intake (DOMI) was significant (r 2 0.70). Nevertheless, the PDC index was affected (P > 0.05) by the level of feed intake and the correlation of the PDC index and DOMI was significant as well (r 2 =0.63). Results of spot urine analysis showed that the sampling period had little or no influence on the concentration of total PD or creatinine in urine. The PDC index was affected by the level of feed intake, but not by the time of sampling. In the second experiment, crossbred milking cows showed a higher PD excretion when fed with the experimental ration as compared with the farm ration. The mean PD excretion were 3.45 and 5.21 mmol/d for farm and experimental diets respectively. Allantoin accounted for more than 80% of the total PD, as in the previous experiment. In conclusion, urinary PD excretion appears to be a valid and non-invasive procedure to assess the microbial protein supply in local Zebu cattle and crossbred milking cows in Sri Lanka. Spot urine sampling also appeared to be a satisfactory method for

    For the past 20 years, the New Zealand Deprivation Index (NZDep) has been the universal measure of area-based social circumstances for New Zealand (NZ) and often the key social determinant used in population health and social research. This paper presents the first theoretical and methodological shift in the measurement of area deprivation in New Zealand since the 1990s and describes the development of the New Zealand Index of Multiple Deprivation (IMD). We briefly describe the development of Data Zones, an intermediary geographical scale, before outlining the development of the New Zealand Index of Multiple Deprivation (IMD), which uses routine datasets and methods comparable to current international deprivation indices. We identified 28 indicators of deprivation from national health, social development, taxation, education, police databases, geospatial data providers and the 2013 Census, all of which represented seven Domains of deprivation: Employment; Income; Crime; Housing; Health; Education; and Geographical Access. The IMD is the combination of these seven Domains. The Domains may be used individually or in combination, to explore the geography of deprivation and its association with a given health or social outcome. Geographic variations in the distribution of the IMD and its Domains were found among the District Health Boards in NZ, suggesting that factors underpinning overall deprivation are inconsistent across the country. With the exception of the Access Domain, the IMD and its Domains were statistically and moderately-to-strongly associated with both smoking rates and household poverty. The IMD provides a more nuanced view of area deprivation circumstances in Aotearoa NZ. Our vision is for the IMD and the Data Zones to be widely used to inform research, policy and resource allocation projects, providing a better measurement of area deprivation in NZ, improved outcomes for Māori, and a more consistent approach to reporting and monitoring the social

    Hospital discharge data are used for occupational injury surveillance, but observed hospitalisation trends are affected by trends in healthcare practices and workers' compensation coverage that may increasingly impair ascertainment of minor injuries relative to severe injuries. The objectives of this study were to (1) describe the development of a severe injury definition for surveillance purposes and (2) assess the impact of imposing a severity threshold on estimated occupational and non-occupational injury trends. Three independent methods were used to estimate injury severity for the severe injury definition. 10 population-based hospital discharge databases were used to estimate trends (1998-2009), including the National Hospital Discharge Survey (NHDS) and State Inpatient Databases (SID) from the Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality. Negative binomial regression was used to model injury trends with and without severity restriction and to test trend divergence by severity. Trend estimates for occupational injuries were biased downwards in the absence of severity restriction, more so than for non-occupational injuries. Imposing a severity threshold resulted in a markedly different historical picture. Severity restriction can be used as an injury surveillance methodology to increase the accuracy of trend estimates, which can then be used by occupational health researchers, practitioners and policy-makers to identify prevention opportunities and to support state and national investments in occupational injury prevention efforts. The newly adopted state-based occupational health indicator, 'Work-Related Severe Traumatic Injury Hospitalizations', incorporates a severity threshold that will reduce temporal ascertainment threats to accurate trend estimates.

  9. Microbial bioenergetics of coral-algal interactions

    Full Text Available Human impacts are causing ecosystem phase shifts from coral- to algal-dominated reef systems on a global scale. As these ecosystems undergo transition, there is an increased incidence of coral-macroalgal interactions. Mounting evidence indicates that the outcome of these interaction events is, in part, governed by microbially mediated dynamics. The allocation of available energy through different trophic levels, including the microbial food web, determines the outcome of these interactions and ultimately shapes the benthic community structure. However, little is known about the underlying thermodynamic mechanisms involved in these trophic energy transfers. This study utilizes a novel combination of methods including calorimetry, flow cytometry, and optical oxygen measurements, to provide a bioenergetic analysis of coral-macroalgal interactions in a controlled aquarium setting. We demonstrate that the energetic demands of microbial communities at the coral-algal interaction interface are higher than in the communities associated with either of the macroorganisms alone. This was evident through higher microbial power output (energy use per unit time and lower oxygen concentrations at interaction zones compared to areas distal from the interface. Increases in microbial power output and lower oxygen concentrations were significantly correlated with the ratio of heterotrophic to autotrophic microbes but not the total microbial abundance. These results suggest that coral-algal interfaces harbor higher proportions of heterotrophic microbes that are optimizing maximal power output, as opposed to yield. This yield to power shift offers a possible thermodynamic mechanism underlying the transition from coral- to algal-dominated reef ecosystems currently being observed worldwide. As changes in the power output of an ecosystem are a significant indicator of the current state of the system, this analysis provides a novel and insightful means to quantify

    Full Text Available The aim of this study was to determine whether increase in proportion of the rumen undegradable starch (RUS and rumen undegradable protein (RUP affects the production performance and health status of calves. The experiment was done on 36 Holstein, seven-day-old calves, divided into three groups of 12 calves, with equal sex ratio. The experiment was conducted in two periods. In the first period, calves were fed with full pasteurized milk and milk replacer and additionally fed with starter mixture with different proportions of rumen undegradable protein and starch: Group I 36.6% RUP and 16.5% RUS, Group II 49.1% RUP and 27.6% RUS and Group III 53.5% RUP and 36.5% RUS. In the second period, calves were fed with milk replacer and grower mixture with different proportions of rumen undegradable protein and starch: Group I 33.5% RUP and 15.8% RUS, Group II 48% RUP and 26.3% RUS and Group III 54.3% RUP and 34.6% RUS. In the first period, calves from the Group III had significantly (P<0.01 higher body weight compared to calves in Group I and II (74.75; 59.36; 66.58 kg, as well as daily weight gain (0.76, 0.49, 0.61 kg/d. At the end of the experiment, there was no significant difference in body weight and daily weight gain. The calves in Group I and III had significantly (P<0.05 higher consumption of starter mixture compared to the calves in Group II (7.48; 7.11; 4.33 kg/d, and a significantly (P<0.05 higher overall feed consumption compared to the calves in Group II. The calves in Group II and III had significantly (P<0.05 better feed conversion ratio than the calves in Group I (1.37; 1.50; 2.08 kg/kg. The results of health monitoring (diarrhea, pneumonia indicate a different proportion of rumen undegradable starch and protein ratio did not have significant effect on calves’ health.

    Health facility-based data reported through routine health information systems form the primary data source for programmatic monitoring and evaluation in most developing countries. The adoption of District Health Information Software (DHIS2) has contributed to improved availability of routine health facility-based data in many low-income countries. An assessment of malaria indicators data reported by health facilities in Kenya during the first 5 years of implementation of DHIS2, from January 2011 to December 2015, was conducted. Data on 19 malaria indicators reported monthly by health facilities were extracted from the online Kenya DHIS2 database. Completeness of reporting was analysed for each of the 19 malaria indicators and expressed as the percentage of data values actually reported over the expected number; all health facilities were expected to report data for each indicator for all 12 months in a year. Malaria indicators data were analysed for 6235 public and 3143 private health facilities. Between 2011 and 2015, completeness of reporting in the public sector increased significantly for confirmed malaria cases across all age categories (26.5-41.9%, p performed and test results were not available in DHIS2 from 2011 to 2014. In 2015, sparse data on microscopy (11.5% for children aged performed were reported in DHIS2 from the private sector. There have been sustained improvements in the completeness of data reported for most key malaria indicators since the adoption of DHIS2 in Kenya in 2011. However, major data gaps were identified for the malaria-test indicator and overall low reporting across all indicators from private health facilities. A package of proven DHIS2 implementation interventions and performance-based incentives should be considered to improve private-sector data reporting.

    This study aimed to develop effectiveness indicators for social marketing communication to reduce health-risk behaviors among Thai youth by using the Delphi technique. The Delphi technique is a research approach used to gain consensus through a series of two or more rounds of questionnaire surveys where information and results are fed back to panel members between each round and it has been extensively used to generate many indicators relevant to health behaviors. The Delphi technique was conducted in 3 rounds by consulting a panel of 15 experts in the field of social marketing communication for public health campaigns in Thailand. We found forty-nine effectiveness indicators in eight core components reached consensus. These components were: 1) attitude about health-risk behavior reduction, 2) subjective norms, 3) perceived behavioral control, 4) intention to reduce health-risk behaviors, 5) practices for reducing health-risk behaviors, 6) knowledge about the dangers and impact of health-risk behaviors, 7) campaign brand equity, and 8) communication networks. These effectiveness indicators could be applied by health promotion organizations for evaluating the effectiveness of social marketing communication to effectively reduce health-risk behaviors among youth.

    A novel method for enhancing gearbox fault diagnosis and prognosis is developed by fusion of multiple health indicators through support vector data description. First, the Comblet transform is used to identify gear residual error signals from the raw signal. Second, based on the observation of gear residual error signals, a total of 11 gear health indicators are identified, and are categorized into two types of indicators. The first and second types of indicators are for fault diagnosis and prognosis, respectively. The first type has six indicators, which are sensitive to impulsive signals triggered by anomalous impacts. The second type has five indicators, which are suitable for tracking degradation of faults. Third, through the support vector data description, the first six health indicators are fused into type one indicators for fault diagnosis. The remaining five indicators are fused into type two indicators for fault prognosis. Finally, a Gaussian kernel is designed to enhance the performance of type one and two indicators by optimal range of width size. The effectiveness of the proposed method is validated through experiments. The new method has been proven to be superior to methods that use unfused indicators individually

    Epidemiological studies have investigated the health impacts of local sources of environmental pollution using as an outcome variable self-reported health, reflecting the overall perception interviewed people have of their own health. This work aims at analyzing the advantages and the results of this approach. A first step focused on describing the indicators. The literature on indicators of self-reported health was reviewed, leading to a discussion on data collection, selection of health effects, data processing, and construction of indicators. The literature review concerned 51 articles. The use of self-reported health indicators allowed the studies to take into account the health concerns and complaints of populations exposed to environmental pollution. Various indicators of self-reported health were used in the studies. They measured physical, psychological and general dimensions of health. Standardized questionnaires were used less often than ad hoc questionnaires (78% of studies) developed to fit the needs of a given study. Three standardized questionnaires were used more frequently: the MOS Short-Form Health Survey (SF-36) to measure general health perceptions, the General Health Questionnaire (GHQ), and the Symptoms Checklist (SCL-90) to measure psychological distress. The choice of self-reported health indicators is a compromise between specificity of the studied health issues within a given environment and standardization of the questionnaires used to measure them. Such standardization is necessary to ensure the validity and the reliability of the information collected across time and situations. The psychometric properties of the measuring questionnaires are rarely estimated or verified when they are used. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Prediction of lithium-ion batteries remaining useful life (RUL) plays an important role in an intelligent battery management system. The capacity and internal resistance are often used as the batteries health indicator (HI) for quantifying degradation and predicting RUL. However, on-line measurement of capacity and internal resistance are hardly realizable due to the not fully charged and discharged condition and the extremely expensive cost, respectively. Therefore, there is a great need to find an optional way to deal with this plight. In this work, a novel HI is extracted from the operating parameters of lithium-ion batteries for degradation modeling and RUL prediction. Moreover, Box-Cox transformation is employed to improve HI performance. Then Pearson and Spearman correlation analyses are utilized to evaluate the similarity between real capacity and the estimated capacity derived from the HI. Next, both simple statistical regression technique and optimized relevance vector machine are employed to predict the RUL based on the presented HI. The correlation analyses and prediction results show the efficiency and effectiveness of the proposed HI for battery degradation modeling and RUL prediction.

    This study evaluated the microbial contamination of health care workers' (HCWs) mobile phones. The study was conducted at a secondary referral hospital in July 2010. Samples were taken from all surfaces of the mobile phones using a sterile swab, and incubated on Brain Heart Infusion agar at 37.5°C for 24 hr. Any isolated microorganisms were grown aerobically on 5% sheep blood agar and eosin methylene-blue agar medium at 37.5°C for 24-48 hr. The Sceptor microdilution system was used to identify the microorganisms, together with conventional methods. The oxacillin disc diffusion test and double-disc synergy test were used to identify methicillin-resistant Staphylococcus aureus (MRSA) and expanded-spectrum beta-lactamase (ESBL)-producing Gram-negative bacilli, respectively. The mobile phones were also categorized according to whether the HCWs used them in the intensive care unit (ICU). Overall, 183 mobile phones were screened: 94 (51.4%) from nurses, 32 (17.5%) from laboratory workers, and 57 (31.1%) from health care staff. In total, 179 (97.8%) culture-positive specimens were isolated from the 183 mobile phones, including 17 (9.5%) MRSA and 20 (11.2%) ESBL-producing Escherichia coli, which can cause nosocomial infections. No statistical difference was observed in the recovery of MRSA (p = 0.3) and ESBL-producing E. coli (p = 0.6) between the HCW groups. Forty-four (24.6%) of the 179 specimens were isolated from mobile phones of ICU workers, including two MRSA and nine ESBL-producing E. coli. A significant (p = 0.02) difference was detected in the isolation of ESBL-producing E. coli between ICU workers and non-ICU workers. HCWs' mobile phones are potential vectors for transferring nosocomial pathogens between HCWs, patients, and the community.

    This study evaluated the relationship between the indices known as the Reef Health Index (RHI) and two-dimensional Coral Health Index (2D-CHI) and different representative metrics of biological, ecological and functional diversity of fish and corals in 101 reef sites located across seven zones in the western Caribbean Sea. Species richness and average taxonomic distinctness were used to asses biological estimation; while ecological diversity was evaluated with the indices of Shannon diversity and Pielou´s evenness, as well as by taxonomic diversity and distinctness. Functional diversity considered the number of functional groups, the Shannon diversity and the functional Pielou´s evenness. According to the RHI, 57.15% of the zones were classified as presenting a "poor" health grade, while 42.85% were in "critical" grade. Based on the 2D-CHI, 28.5% of the zones were in "degraded" condition and 71.5% were "very degraded". Differences in fish and coral diversity among sites and zones were demonstrated using permutational ANOVAs. Differences between the two health indices (RHI and 2D-CHI) and some indices of biological, ecological and functional diversity of fish and corals were observed; however, only the RHI showed a correlation between the health grades and the species and functional group richness of fish at the scale of sites, and with the species and functional group richness and Shannon diversity of the fish assemblages at the scale of zones. None of the health indices were related to the metrics analyzed for the coral diversity. In general, our study suggests that the estimation of health indices should be complemented with classic community indices, or should at least include diversity indices of fish and corals, in order to improve the accuracy of the estimated health status of coral reefs in the western Caribbean Sea.
