This article provides an overview of the ways in which the home environment can affect human health, describes how specific
health hazards in housing are related, and considers implications of these concerns for research and programs to address the
health-housing connection. The widespread availability of decent housing has contributed greatly to improvements in health
status in developed countries through, for example, provision of safe drinking water, proper sewage disposal, and protection
from the elements. However, a lack of decent housing and homelessness among a significant number of Americans remains a significant
public health concern. In addition, a number of specific health hazards can be found even in housing that is in good condition
and provides all basic amenities. Specific health hazards related to housing include unintentional injuries, exposure to lead,
exposure to allergens that may cause or worsen asthma, moisture and fungi (mold), rodent and insect pests, pesticide residues,
and indoor air pollution. A number of these specific hazards share underlying causes, such as excess moisture, and all may
be influenced by factors in the community environment or by occupant behaviors. We make recommendations for developing programs
and research efforts that address multiple housing problems in an integrated way, rather than categorically, and for closer
collaboration between housing and public health programs.

The environmental justice literature has described differential health effects of environmental toxins and pollutants on people of different socio-economic status (SES) that may not always reflect differing levels of exposure. We offer four questions or contentions that together may contribute to understanding this conundrum and then present an empirical exploration of one of these questions: Does the relationship between SES and self-perceived status vary in space? Utilizing data from an original questionnaire survey of randomly selected adults conducted in twenty-five communities in British Columbia, Canada, a supplementary data set containing demographic and socio-economic characteristics of the communities themselves, and multilevel modelling techniques, this article describes relationships between objective and subjective measures of social status, by gender and in space. Our analysis contributes to the development of innovative environmental justice models by bringing some spatial sensitivity to interrelationships among these aspects of status. 相似文献

This work presents results from analytical as well as ecotoxicologic investigations of sediment and water samples from the
North and Baltic Seas. A bioassay-directed procedure was used to investigate cause–effect relationships between observed effects
in acute laboratory bioassays (luminescent bacteria assay with Vibrio fischeri and embryo test with Danio rerio) and analyte concentrations in extracted samples. Brominated phenols and indoles—including 4-bromophenol; 2,4-dibromophenol;
4- and 6-bromoindole; 3,4-, 4,6-, and 3,6-dibromoindole; and tribrominated compounds—were identified in partly remarkable
concentrations (up to 40,000 ng g−1 total organic carbon TOC for 4-bromophenol) in North Sea sediment samples and water samples (913 ng L−1 3,6-dibromoindole) from the German Bight. The toxicity of some of the identified brominated substances was low, with median
effect concentration levels (EC50) ranging from 0.08 to 21.7 mg/L for V. fischeri and 4.3 to 46.3 mg/L for D. rerio. Comparison of the concentrations of analytes with ECs showed a toxicity contribution of brominated phenols and indoles to
overall toxicity of the fraction. In the case of one water sample from the German Bight, brominated phenols and indoles accounted
for the observed toxicity. Brominated phenols and indoles, which are assumed to be of biogenic origin, have rarely been discussed
so far in the context of ecotoxicologic effects in marine ecosystems. 相似文献

To improve our understanding of the metabolism of ornithine α-ketoglutarate (OKG), used as an adjuvant of parenteral nutrition, we studied the plasma kinetics, localisation of target tissues and metabolism of α ketoglutarate (αKG) and ornithine (Orn) in healthy and burned animals. After parenteral administration, the kinetics of plasma disappearance of the two labelled compounds showed a biphasic decrease reflecting an open two-compartmental model of elimination, with the exception of Orn in burned rats. The appearance of metabolites in the plasma was rapid, particularly with regard to glutamate, proline and, following ornithine administration, glutamine. This witnessed the engagement of the substrates in multiple metabolic pathways. The study of tissular distribution by autoradiography demonstrated certain target tissues in common for αKG and Orn such as the liver, intestinal mucosa, salivary glands, kidney and muscle. This is consistent with a possible synergic action of these two compounds. The identification of labelled amino-acids and aliphatic polyamines was also performed in the tissues. Two major observations were made, which could be of interest in further work concerning cellular mechanisms of OKG action. Firstly, after αKG administration, labelled Glu and αKG were detected simultaneously in muscle; this would render possible the local biosynthesis of the anticatabolic compound α ketoisocaproate. Secondly, the injection of 14C-ornithine was followed by the appearance in the intestinal mucosa and salivary glands of labelled aliphatic polyamines, which possess an anabolic effect. 相似文献

In adults, burns of 40% total body surface areas(TBSA)or greater were virtually unsurvivable but a few decades ago.Now, more than half of the adult patients with a 70% TBSA burn survive. In children, the size of the survivable injury has increased so much that it is now possible to save a child with burns exceeding 95% TBSA full thickness.The decrease in mortality and morbidity related to major thermal burn injuries noted in the past decade is primarily due to improvements in four major areas. 相似文献

OBJECTIVES: Although increasing effort is being devoted to developing strategies to increase knowledge transfer and the uptake of health technology assessment (HTA) by various stakeholders, very little is known about the utilization and dissemination of HTA findings by patient and consumer organizations. The goal of this study is to understand how and why patient and consumer organizations use HTA findings within their organizations, and what factors influence how and when they communicate their findings to members or other organizations. METHODS: We examined the use and dissemination of four controversial HTA reports by sixteen patient and consumer organizations in Ontario and Quebec. We gathered data from semistructured interviews conducted between December 2006 and April 2007. RESULTS: Although HTA findings are often used by the patient and consumer organizations, key differences were observed in exactly how the four HTA reports were used. Three types of use (instrumental, conceptual, and symbolic) are reported and illustrated. We highlight the importance of the organization's mission and knowledge base in explaining the types of use observed. CONCLUSIONS: We contend that the use and dissemination of HTA reports by specific groups could help in widening the debate around controversial health technologies. The implications and opportunities for HTA agencies relate to the following: (i) identification of "lay" organizations that could help in disseminating results; (ii) acknowledgement of a "lay" audience for HTA findings; (iii) strategic inclusion of advocacy groups during the assessment process for highly controversial technologies; and (iv) contribution of these organizations to the push efforts of knowledge transfer. 相似文献

Previous studies have indicated that the δ-carboline (2) ring system derived from the natural product cryptolepine (1) may represent a pharmacophore for anti-infective activity. This paper describes the design and synthesis of a small library of substituted δ-carbolines and the evaluation of the anti-fungal and anti-bacterial activities. An evaluation of the anti-bacterial activity of a previously reported library of ring-opened analogs was also conducted to provide an opportunity to test the hypothesis that both group of compounds may have the same biological target. Results indicate that against a selected group of fungal pathogens, substituted δ-carbolinium analogs displayed higher potency and several fold lower cytotoxicity than cryptolepine the parent natural product. Both the δ-carbolinium compounds and their ring-opened analogs, exhibited equally high anti-bacterial activity against the selected pathogens and especially against the gram positive bacteria evaluated. 相似文献

PurposeAdolescence is a key stage for forming knowledge and attitudes about sex and reproduction that may have long-term implications for adult sexual behaviors. Gender differences in experiences and socialization processes may affect the links between adolescent characteristics and adult behaviors.MethodsBy following adolescent virgins aged 15 years and older from wave I through wave IV of the National Longitudinal Study of Adolescent to Adult Health (n = 4,152), we test whether adolescent boys' and girls' knowledge about, and attitudes toward, sex and reproduction influence the number of lifetime different-sex sexual partners and the likelihood of having concurrent sexual partners in adulthood, using negative binomial regression and logistic regression, respectively. Models are run separately by gender.ResultsMen and women who reported greater physical benefits of sex as adolescents reported more lifetime different-sex sexual partners and were more likely to have concurrent sexual partners in adulthood. For women, adolescent perceptions of more social costs to sex were linked to fewer lifetime sexual partners, whereas greater birth control confidence was linked to more sexual partners. Women who more strongly felt that avoiding sexually transmitted infections was a hassle during adolescence were less likely to have concurrent sexual partners as adults, and men who were more knowledgeable about condoms during adolescence were more likely to have concurrent sexual partners.ConclusionsAdolescent knowledge and attitudes about sex, contraception, and reproduction have implications for adult sexual behavior, but different aspects emerge as salient for men and women. 相似文献

Objective
The current study aimed to examine the interplay between self-efficacy and perceived availabilities of fruits and vegetables (F&V) and energy-dense, low-nutrient foods and sugary drinks (EDLNF&SD) at home and in the school neighborhoods on adolescents’ eating behaviors.Design
The Family Life, Activity, Sun, Health, and Eating study, a cross-sectional, Internet-based survey was analyzed.Participants
Adolescent–parent dyads (n?=?1,657).Interventions
Self-efficacy for F&V intake and limiting EDLNF&SD consumption, perceived F&V and EDLNF&SD availabilities at home and in the school neighborhood, and F&V intake and EDLNF&SD consumption.Analysis
Multiple regression analyses.Results
Adolescents’ self-efficacy and perceived home and school neighborhood availability of F&V and EDLNF&SD had significant main effects on their F&V intake and EDLNF&SD consumption, respectively (all P < .01). The positive effect of self-efficacy on F&V intake was greater when home F&V availability was high (+1 SD; b?=?.29; P < .001) than when it was low (–1 SD; b?=?.07; P?=?.040). The effect of home F&V availability on F&V intake was significant when F&V were not available in the school neighborhood (b?=?.09; P?=?.006).Conclusions and Implications
Given the central role of home availability, it may be considered a fundamental unit of nutrition intervention for adolescents. Multiple contexts (eg, individual, home, school neighborhood) need to be considered to promote adolescents’ eating behaviors. 相似文献16.

Expectations are growing that literature may contribute to clinical skills. Narrative medicine is a quickly expanding area
of research. However, many people remain sceptical to the idea of literature having a capacity to “save the life of medicine”.
It is therefore urgent to scrutinize both the arguments in favour of and those against the potential of literature for increasing
medical understanding. This article attempts to do this. It does in fact support the assertion that literature is important,
but it stresses precisely its character of potential. There is no simple connection between acquaintance with literary texts
and understanding of the different aspects of medical work. Much more need to be known about the conditions which allow the
experiences residing in texts to be transformed into lived personal knowledge.

The 2010 Patient Protection & Affordable Care Act (ACA) significantly expanded access to private and public health insurance for low-income individuals through income-based subsidies and income-based eligibility expansions, respectively. In this paper, we use the universe of hospitals from 2009 to 2015 to characterize how these expansions affected the financing of hospital visits, along with price, utilization, and potential spillovers in the quality of care. The insurance coverage expansions generated a shift in the composition of payers and a modest increase in the utilization of hospital outpatient services. While concerns have been raised that these shifts in utilization could cause negative spillovers to the already insured population (e.g., Medicare enrollees), we find no significant change in the quality of care experienced by those already insured. The primary result of both federally funded insurance expansions was to increase the profits generated and prices charged by the hospitals providing such services. 相似文献

Over the past 30 years, and increasingly over the past decade, palliative care services characteristically address the complexity of communication, decision making, and management of end-of-life issues for patients and families of all ages. Clinical ethics services have a parallel 30-plus year history in the United States-so much so that some have offered that clinical ethics has "cut its teeth" on issues attendant to the beginning and end of life. The authors propose considerations necessary in determining the appropriateness of consultation with palliative care, clinical ethics, or both, and when either may be necessary but perhaps not sufficient for patient and family management. A resolution for any encountered tension and identification of common or overlapping domains for both consultants is presented. 相似文献
