Based on the quality evaluation methods, domains and quality criteria (described above and detailed for all studies in Supplementary Tables 5, 6), most of the studies assessing pulmonary cancer risk among talc miners and millers were rated medium quality.

WebFinal Screening Assessment for Talc (Mg3H2(SiO3)4) (published on April 22, 2021). Feb., 1980. The normalized lung talc burdens for both mice and rats were lower at the lowest exposure level than at the two higher exposure levels; however, the difference was statistically significant only for the rats. WebTalc is a mineral made up mainly of magnesium, silicon, and oxygen. In general, potential confounders such as age were appropriately considered in the statistical analyses, and employment records were used to extract key demographic and work history information. An overview of our methods is provided below, and an example of their application can be seen in a recent review on ethylene oxide (9). Our evaluation of reproductive tract cancers, following the same methods as the current review, to be presented in a companion manuscript (10). Gamble JF. Two nested case-control studies were conducted in tandem with occupational mortality analyses (30, 31). Although the paucity of mechanistic information remains a limitation, the balance of evidence, especially the volume of epidemiological evidence demonstrating no increased cancer risks associated with even the highest real world human-relevant exposures, strengthens the current analysis. 0000000016 00000 n To comment on this thread you need to create a Mumsnet account. For each cohort, excluding the Austrian and French cohorts, mortality was updated at least once. Webbreathing in loose talc powder may cause lung effects, such as coughing, trouble breathing, decreased lung function and fibrosis; and. Lines are open from9am to 5pmMonday to Friday(excluding bank holidays). Our systematic review methods adhere to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and incorporated aspects from the US Institute of Medicine (IOM) and several United States (US) Environmental Protection Agency (EPA) frameworks for systematic reviews. Ierardi AM, Marsh GM. Further, the physicochemical properties of non-fibrous talc (e.g., inertness) and recent evaluations of potential MOAs indicate talc poses little to no concern for carcinogenic effects in humans, especially at less than lung overload exposures. This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). The available data indicate that talc dust exposure in the modern mining of cosmetic grade talc does not appear to be injurious to health and the significantly lower dust Exposure in the normal use of cosmeticgrade talcdusts in talc-containing health and cosmetic products confirms that their use is not a hazard to health.

Inhalation of talc induces infiltration of macrophages and upregulation of manganese superoxide dismutase in rats. Quantitative Synthesis. Figure 1. Long term sequelae after talc pleurodesis for spontaneous pneumothorax. The body of epidemiological evidence does not demonstrate a clear or consistent increase in mortality from lung cancer among talc miners and millers. Am J Ind Med. We employed qualitative and hierarchical or tiered approaches to arrive at the overall study quality score, tailored to each study type and outcome. Particle overload is common when high doses of poorly insoluble particles are administered particle clearance mechanisms of the lung are overwhelmed and carcinogenic processes are initiated (23, 24): see Mechanistic evidence and Mode of Action. There was no evidence of carcinogenicity in mice exposed to talc. Integration of evidence included consideration of consistency, coherence and the presence of exposure-response relationships. The authors observed increases in macrophage infiltration at 50 and 100 mg/m3 talc, but not at the lowest concentration of 5 mg/m3. However, the authors noted that these tumors were metastatic and that there were no primary neoplasms found in the respiratory system. Ann Occup Hyg. This exposure assessment focuses on routes of exposure where critical effects have been identified; namely, non-cancer lung effects following inhalation of insoluble respirable particles of talc, and an association with ovarian cancer following perineal exposure to talc. Selevan SG, Dement JM, Wagoner JK, Froines JR. Mortality patterns among miners and millers on non-asbestiform talc: Preliminary report. Briefly, the cohorts ranged in size from about 400 (53) to over 1,700 (1) miners and millers that were followed for mortality for up to seven decades. (1987() 87:22234. Features. Typical conditions that require a Test of Abstract Language Comprehension. (2020) 44:2118. In:Dusts and Disease, Lemen R., Dement J.M, , editors. 792 children aged 4 to 16 years and 70 adults participated from 10 regions across the United Kingdom. (56) reported that the death certificate for the single mesothelioma death in the cohort explicitly mentioned exposure to asbestos; yet no additional information was available regarding this potential exposure (56). (2014) 42:86376. The objective of this paper was to apply systematic review methods to critically evaluate and synthesize the scientific evidence addressing the possible relationship(s) between exposure to talc occupationally and from exposure to talc-containing products (primarily talcum powders and cosmetics) and pulmonary cancers, specifically lung cancer and pleural mesothelioma, integrating epidemiology, toxicology, and studies informing potential underlying modes of action. Wehner et al. Can be used to set targets to encourage development of abstract reasoning skills. Specifically, this framework involves reviewing and evaluating studies according to specific quality domains (e.g., outcome assessment and exposure characterization), each of which includes two to seven individual metrics assessing specific study features.

Stille and Tabershaw (47) updated the earlier cohort study and reported that all workers combined showed a moderate excess of lung cancer deaths (SMR = 1.57; no CI reported) (47). However, the lung tumors occurred only in female rats exposed at a dose also inducing significant chronic lung toxicity and high lung talc burden, such that the maximum tolerable dose may have been exceeded (21). When stratified by employment history, talc workers with known prior employment also showed excess lung cancer mortality (SMR = 2.14; no CI reported), and talc workers with no known work prior to their talc facility employment showed a slight deficit of lung cancer deaths (SMR = 0.76; no CI reported). The increased risk appeared to be limited to workers hired before 1955 (SMR pre-1955: 2.86; 95% CI: 1.904.14), as the SMR for workers hired after 1955 was 0.83 (95% CI: 0.172.42).

Some of the popular cosmetic ingredients discussed in this paper may exert a negative influence on human health, and many of these harmful effects have been discovered recently. Canad Resp J.

We pilot tested the case-control quality evaluation for Gamble (31) and determined that its rating was equivalent to the associated cohort study (41) and thus did not separately evaluate the second case-control study.

Public comments received on the draft screening assessment and risk management scope Calculated cumulative talc exposures were 12, 120, and 600 mg-h/m3 for 30 days or 1,200 and 6,000 mg-h/m3 for the 300-day groups. Poorly Soluble Particles/Lung Overload: Technical Report No. Risk Science Institute ILSI. Generally, aerosolized talc has an alveolar biological half-life of about 710 days in animals.

However, high quality ratings were rare due to inadequate information on prior employment history among the cohort members, which precluded determining the potential for prior occupational exposure to asbestos.

Across all cohort studies, observed numbers of deaths for site-specific cancers among talc miners and millers (either combined or separately) were compared with expected numbers based on national and/or regional reference rates.
