  • Racial and Ethnic Disparities in Health Care, Updated 2010
    RACIAL AND ETHNIC DISPARITIES IN HEALTH CARE, UPDATED 2010 American College of Physicians A Position Paper 2010 Racial and Ethnic Disparities in Health Care A Summary of a Position Paper Approved by the ACP Board of Regents, April 2010 What Are the Sources of Racial and Ethnic Disparities in Health Care? The Institute of Medicine defines disparities as “racial or ethnic differences in the quality of health care that are not due to access-related factors or clinical needs, preferences, and appropriateness of intervention.” Racial and ethnic minorities tend to receive poorer quality care compared with nonminorities, even when access-related factors, such as insurance status and income, are controlled. The sources of racial and ethnic health care disparities include differences in geography, lack of access to adequate health coverage, communication difficulties between patient and provider, cultural barriers, provider stereotyping, and lack of access to providers. In addition, disparities in the health care system contribute to the overall disparities in health status that affect racial and ethnic minorities. Why is it Important to Correct These Disparities? The problem of racial and ethnic health care disparities is highlighted in various statistics: • Minorities have less access to health care than whites. The level of uninsurance for Hispanics is 34% compared with 13% among whites. • Native Americans and Native Alaskans more often lack prenatal care in the first trimester. • Nationally, minority women are more likely to avoid a doctor’s visit due to cost. • Racial and ethnic minority Medicare beneficiaries diagnosed with dementia are 30% less likely than whites to use antidementia medications.

Human Health as another major challenge of Global Soil Security Florence Carré, Julien Caudeville, Roseline Bonnard, Valérie Bert, Pierre Boucard, Martine Ramel Abstract This chapter aimed to demonstrate, by several illustrated examples, that Human Health should be considered as another major challenge of global soil security by emphasizing the fact that (a) soil contamination is a worldwide issue, estimations can be done based on local contamination but the extent and content of diffuse contamination is largely unknown; (b) although soil is able to store, filter and reduce contamination, it can also transform and make accessible soil contaminants and their metabolites, contributing then to human health impacts.

  • Frequently Asked Questions
    FACT SHEET Frequently Asked Questions How can I find out today's air quality? Citizens can call a smog recording at (858) 586-2800 which gives the day's maximum pollution levels listed by monitoring stations and the forecasted pollution levels for the next day. The recording is updated at 4:30 p.m. each weekday. The recording also provides advance notice if there is the potential for unhealthful air quality. Air quality information can also be obtained through this web site (www.sdapcd.org) under Current Air Quality. Why do we need to regulate air quality? Because it involves the health of our community. All of us face some health risk from polluted air. Short-term exposure to smog (ozone) for an hour or two can add stress to the body. It is a strong irritant that can cause constriction of the airways, forcing the respiratory system to work harder in order to provide oxygen. Chronic exposure to smog can reduce lung capacity, lower stamina, and leave people more vulnerable to long-term respiratory problems. Smog is especially harmful for children whose lungs are still developing, senior citizens whose immune systems are breaking down, and those who suffer from heart or lung disease. Another pollutant, inhalable particles, can increase the number and severity of asthma attacks and cause or aggravate bronchitis and other lung diseases. Tiny particles, 2.5 microns or less in diameter, are so small they can penetrate deep into the lungs and damage lung tissue. Safeguarding our air quality is the primary focus of our regulatory system.

M. Skłodowskiej-Curie 62, 59-301 Lubin, Poland; [email protected] (M.P.); [email protected] (W.S.) * Correspondence: [email protected]; Tel.: +48-7132-028-68 Received: 12 November 2020; Accepted: 9 December 2020; Published: 18 December 2020 Abstract: In underground mines, mobile mining equipment is critical for the production system. The microenvironment inside the mobile machine may cause exposure to strongly polluted mine air, which adversely affects the health and working performance of the operator. Harmful pollutants may access the cabin together with the ventilation air delivered from the machine’s surroundings. This work proposes a solution that is able to ensure that the air for the machine operator is of proper quality. The proposal emerged from an analysis of the compliance of cabins of mobile machines working underground in mines with occupational health and safety (H&S) standards. An analytical model of air quality in a well-mixed zone was utilized for this purpose. The cabin atmosphere was investigated with regard to the concentration of gaseous species in the surrounding air, the cabin ventilation rate, and human breathing parameters. The analysis showed that if currently available ventilation approaches are used, compliance with multiple H&S standards cannot be attained inside the cabin if standards are exceeded in the surroundings of the machine.

  • What the Public Thinks About Menatl Health and Mental Illness
    What the Public Thinks about Mental Health and ~entaleI1lness A paper presented by Shirley A. Star, Senior Study Director National Opinion Research Center, University of Chicago to the Annual Meeting The National Association for Mental Health, Inc. November 19, 1952 For the past two and a half years, the National Opinion Research Center has been engaged upon a pioneering study of the-American public's thinking in the field of mental health, under the joint sponsorship of the National Association for Mental Health and the National Institute of Mental Health, It is a vast and ambitious project, and I'm afraid that the title which has been assigned to my remarks about .the study is going to prove to be misleading in at least two ways. In the first place, and this must be obvious, both the title given me and the scope of the study cover Ear more ground than I could possibly present in the course of one afternoon. About all I can do today is hit a few of the high spots in public thinking and emphasize beforehand that the study aims to be inclusive. You can pretty well assume that it contains some information on just about any question in the area you might raise, even though I don't refer to many of them. So, as they say in the more enterprising shops--"If you don't see what you want, ask for it," In the second place, and this is more serious, I am in the em- barrassing position of having to stand here this afternoon and honestly- -2- admit that I don1t -know what the public thinks as yet.

  • Indoor Air Quality
    Indoor Air Quality Poor indoor air quality can cause a stuffy nose, sore throat, coughing or wheezing, headache, burning eyes, or skin rash. People with asthma or other breathing problems or who have allergies may have severe reactions. Common Indoor Air Pollutants Poor indoor air quality comes from many sources, including: » Tobacco smoke » Mold » Pollen » Allergens such as those from cats, dogs, mice, dust mites, and cockroaches » Smoke from fireplaces and woodstoves » Formaldehyde in building materials, textiles, and furniture » Carbon monoxide from gas furnaces, ovens, and other appliances » Use of household products such as cleaners and bug sprays » Outdoor air pollution from factories, vehicles, wildfires, and other sources How to Improve Indoor Air Quality » Open windows to let in fresh air. • However, if you have asthma triggered by outdoor air pollution or pollen, opening windows might not be a good idea. In this case, use exhaust fans and non-ozone-producing air cleaners to reduce exposure to these triggers. » Clean often to get rid of dust, pet fur, and other allergens. • Use a vacuum cleaner equipped with a HEPA filter. • Wet or damp mopping is better than sweeping. » Take steps to control mold and pests. » Do not smoke, and especially do not smoke indoors. If you think poor indoor air is making you sick, please see or call a doctor or other health care provider. About CDC CDC is a federal public health agency based in Atlanta, GA.

  • Core Principles to Reframe Mental and Behavioral Health Policy 2
    Getty Images / Maskot Core Principles to Reframe Mental and Behavioral Health Policy January 2021 Historic and modern-day policies rooted in discrimination and oppression have created and widened harmful inequities impacting many communities of color. Effectively and equitably addressing mental health requires intervening at systemic and policy levels to dismantle the structures that produce negative outcomes like generational poverty, intergenerational and cultural trauma, racism, sexism, and ableism. Changing social, economic, and physical environments alongside key mental and behavioral health supports through immediate relief and longer-term fixes impact individual and community mental health and wellbeing. An individual’s mental health is impacted by and informs nearly every aspect of their life, identity, and community. CLASP looks at how one’s social, economic, and physical environment impact individual and community views of mental health and wellbeing. To improve mental health outcomes, we must think about an individual and family’s economic security, family support, and their community’s built environment. CLASP recognizes the influence of intergenerational and cultural trauma on communities and believes that all mental and behavioral health practices should be trauma-informed and healing- centered. Policymakers must significantly reform and reimagine systems that support the wellbeing of people with low incomes. This includes, but is not exclusive to: • Universal health coverage, as noted in our health care principles; • Recognizing

Helsinki 1996, 65 pp. ISBN 951-712-094-X ISSN 0781-1705 Key words Radioactive particles, in-field gamma-ray spectrometry, emergency preparedness ABSTRACT Rapid and accurate measurements must be carried out in a nuclear disaster that releases radioactive material into the atmosphere. To evaluate the risk to the people, .external dose rate and nuclide-specific activity concentrations in air must be determined. The Finnish Centre for Radiation and Nuclear Safety (STUK) has built an emergency vehicle to accomplish these tasks in the field. The present paper describes the systems and methods to determine the activity concentration in air. Airborne particulate sampling and gamma-ray spectrometric analysis are quantitative and sensitive tools to evaluate the nuclide-specific concentrations in air. The vehicle is equipped with a pump sampler which sucks air through a glassfiber filter (flow about 10 1 s"1). Representative sampling of airborne particles from a moving vehicle is a demanding task. According to the calculations the total collection efficiency in calm air is 60 -140% for the particle size range of 0.1 - 30 um.
