Particulate Matter

Particles of any solid substance, generally under 30 microns in size, often noted as PM30. There is special concern with PM1 which can get down to PULMONARY ALVEOLI and induce MACROPHAGE ACTIVATION and PHAGOCYTOSIS leading to FOREIGN BODY REACTION and LUNG DISEASES.

1.	Asthma (Bronchial Asthma) 08/01/2013 - "Several studies highlight the efficacy of portable HEPA purifiers in reduction of indoor particulate matter and improving asthma outcomes. " 04/01/2015 - "In the present study, we examined associations between source contributions of fine particulate matter and emergency department visits for pediatric asthma in Atlanta, Georgia (2002-2010) using a novel ensemble-based SA technique. " 03/17/2015 - "This study was designed to investigate whether different types of near-road particulate matter (PM) contribute to exacerbation of allergic asthma. " 02/01/2015 - "Relative risk (RR) or odds ratio (OR) and 95% confidence intervals (CI) of asthma hospital admissions per 10 µg/m³ increase of daily particulate matter were obtained from each study. " 02/01/2015 - "The PubMed, Ebsco, Ovid and four Chinese periodical databases were screened for studies related to short-term effects of particulate matter on pediatric asthma hospital admissions published from 1 January 1990 to 31 December 2013.Sixteen studies on PM(10) and 10 studies on PM(2.5) were selected finally for meta-analysis. "
2.	Infection 09/01/1977 - "Tentative conclusions concerning the role of recognition and ingestion of microorganisms by phagocytes in host defense and the consequences of disorders of phagocytosis can be derived by correlating a) knowledge about recognition and ingestion derived from studies in vitro, b) investigations of the clearance of particulate matter from the circulation of animals and man, and c) analyses of the behavior of phagocytes in patients susceptible to recurrent pyogenic infections. " 01/01/2006 - "This has been attributed to its complex anatomy and prominent reticuloendothelial functions which include clearance of unwanted particulate matter in blood ( culling), defense against infection and reservoir for blood cells. " 11/01/2014 - "This study aimed to assess the effect of environmental particulate matter (PM) and other important risk factors on 1-year PD-related infection in patients undergoing PD.A total of 175 patients undergoing PD were recruited in this 1-year retrospective observational study. " 07/01/2013 - "The main purpose of this study is to assess the impact of prenatal exposure to fine particulate matter (PM2.5) on the recurrent broncho-pulmonary infections in early childhood. " 12/01/2009 - "The objective of the study presented here was to determine the relationship between air pollution from particulate matter less than or equal to 10 microm in aerodynamic diameter (PM10; mostly PM2.5, or particulate matter <2.5 microm in aerodynamic diameter) and health effects measured as the daily number of deaths, hospital admissions, and emergency room visits for cardiovascular, respiratory, and acute respiratory infection (ARI) diseases. "
3.	Pneumonia (Pneumonitis) 07/01/2013 - "Statins reduce lung inflammation by promoting the clearance of particulate matter from lung tissues." 03/15/1997 - "The experimental protocols employed in the above inhalation studies permitted examination of (1) the impact of species, size, handling stress, and changes in Ta on both the induced hypothermic response and the concomitant pulmonary toxicity; (2) the additive impact of exercise stress on O3 toxicity; and (3) the toxicity of ambient-derived particulate matter in normal rats and in rats with preexisting pulmonary inflammation. " 11/01/2014 - "In conclusion, associations between particulate matter mass exposure and pneumonia were not explained by the elements we investigated. " 11/01/2014 - "We assessed associations between eight particulate matter elements and early-life pneumonia in seven birth cohort studies (N total=15,980): BAMSE (Sweden), GASPII (Italy), GINIplus and LISAplus (Germany), INMA (Spain), MAAS (United Kingdom) and PIAMA (The Netherlands). " 11/01/2014 - "Associations between particulate matter elements and early-life pneumonia in seven birth cohorts: results from the ESCAPE and TRANSPHORM projects."
4.	Sepsis (Septicemia) 02/01/1989 - "Severe sepsis leads to depression of the reticuloendothelial (RE) system with delayed bloodstream clearance of particulate matter and bacteria. " 02/01/1988 - "Severe sepsis leads to depression of the reticulo-endothelial system (RES) with delayed bloodstream clearance of particulate matter and bacteria. " 07/01/1983 - "Following splenectomy (SPLY) there is increased retention in the lung of injected particulate matter and an increased mortality from sepsis in experimental animals. " 09/01/1981 - "The reticuloendothelial system (RES) is thought to ensure organ integrity following trauma, burn, and sepsis by removing potentially embolic particulate matter and blood-borne bacteria from the circulation. "
5.	Wounds and Injuries (Trauma) 11/01/2013 - "Through 8 different transport scenarios, the number of cases of disease or injuries related to physical activity, particulate matter air pollution <2.5 μm (PM2.5) and traffic incidents in travelers was estimated. " 04/01/2013 - "We measured the change in disease burden in disability-adjusted life years (DALYs) based on dose-response relationships and the distributions of physical activity, particulate matter, and traffic injuries. " 04/01/2013 - "Statistics on travel patterns and injuries, physical activity, fine particulate matter, and GHGE in the San Francisco Bay Area, California, were input to a model that calculated the health impacts of walking and bicycling short distances usually traveled by car or driving low-emission automobiles. " 03/01/2011 - "Mechanisms of cardiovascular injuries from exposure to gas and particulate air pollutants are unknown. " 03/01/2002 - "In cases of severe eye trauma or as a result of certain diseases and medical conditions, particulate matter may be introduced into the anterior chamber. "
