A limited number of published studies have evaluated concentrations of airborne fibers in outdoor air, with even fewer assessing typical air concentrations in the ambient air near fiberglass wool manufacturing facilities. Building upon the assessment by Switala et al. (1994), area samples for airborne fiber concentrations (diameters of less than 3 µm, lengths greater than 5 µm, and aspect ratios equal to or greater than 5 to 1) were collected at fixed locations along the fence lines of three fiberglass wool manufacturing facilities in the United States.

Potential health effects from occupational exposure to MMVF have been investigated since the 1970s, with focus on incidence of respiratory tract cancer among MMVF-exposed production workers. The general population may experience exposure to MMVF in residential and/or commercial buildings due to deterioration, construction, or other disruption of materials containing these fibers.

- * A total of 23 studies were analyzed, with 9 studies on mortality showing generally no link between MMVF exposure and increased risk of NMRD mortality, while the remaining 14 focused on respiratory symptoms without strong evidence of an association.
- * The review highlights limitations in the existing studies, such as outdated data, reliance on self-reported information, and calls for future research to address these flaws for a clearer understanding of the health impacts of MMVF exposure.
Article Synopsis
- * Our search on MEDLINE/PubMed and Web of Science identified studies that we analyzed, showing a pooled relative risk (RR) of RTC among MMVF-exposed workers at 1.09.
- * However, when considering studies that accounted for key risk factors like asbestos and smoking, the RR decreased to 1.03, suggesting that MMVF exposure is not significantly associated with an increased risk of RTC.
Background: Perceived neighborhood characteristics, including satisfaction with one's neighborhood as a place to live, are associated with lower obesity rates and more favorable cardiovascular risk factor profiles. Yet, few studies have evaluated whether changes in perceived neighborhood characteristics over time may be associated with cardiometabolic health indicators.
Methods: Changes in perception of one's neighborhood (2013-2016) were determined from a cohort of residents who lived in one of two low-income urban neighborhoods.
Context: Endogenous sex hormones may be involved in the pathogenesis of cardiovascular disease (CVD) in women. Carotid plaque characteristics, such as echogenicity, an ultrasound measure that reflects plaque composition, may identify unstable plaques that are more likely to rupture, precipitating a CVD event. However, few studies have considered sex steroids in relation to carotid plaque and its characteristics.

We utilized an exploratory factor analysis (EFA) to identify distinct factors derived from circulating inflammatory and coagulation biomarkers then examined the associations of these factors with measures of lower extremity subclinical atherosclerosis, including the ankle-brachial index (ABI), common and superficial femoral intima-media thickness (IMT), and atherosclerotic plaque presence, burden, and characteristics.
Methods: The San Diego Population Study (SDPS) is a prospective, community-living, multi-ethnic cohort of 1103 men and women averaged age 70.
