The president's scientist.

The science advisor to the US president has the opportunity to influence how scientific research is supported by the federal government, as well as the ways in which science and technology can be applied to meet the needs of society.

Promoting Coordination and Collaboration in Tribal Home Visiting Programs in the United States.

BACKGROUND: A joint statement from two federal agencies in the United States calls for coordination and collaboration between programs serving families of infants and toddlers who are at risk or developmentally delayed or disabled U.S. Department of Education and U.S. Department of Health and Human Services. Policy guidance: Joint statement on collaboration and coordination of the MIECHV and IDEA Part C programs. (2017). Individuals with Disabilities Education Act. ED/HHS Joint Guidance Document: Collaboration and Coordination of the Maternal, Infant, and Early Childhood Home Visiting Program and the Individuals with Disabilities Education Act Part C Programs. Young Native American children living on tribal lands in this country are currently eligible for two federal programs associated with these agencies which overlap in mission and implementation. PURPOSE: This paper outlines potential strategies for creating a more seamless system of services for tribal families involving more centralized intake processes and procedures, cross training of staff to work across programs, and adopting more unifying approaches to program implementation. CONCLUSION: A streamlined system of services will result in interventions that better support family and child outcomes while reducing duplication of services, consolidating the limited number of qualified professionals available to provide services, and increasing convenience and cultural attunement of services to Native American families currently participating in both programs.

From urban dust and marine sediment to Ginkgo biloba and human serum-a top ten list of Standard Reference Materials (SRMs).

During the past 40 years, the National Institute of Standards and Technology (NIST) has developed over 180 natural matrix Standard Reference Materials® (SRMs) for the determination of trace organic constituents in environmental, clinical, food, and dietary supplement matrices. A list of the Top Ten SRMs intended for organic analysis was identified based on selection criteria including analytical challenge to assign certified values, challenges in material preparation, novel matrices, longevity, widespread use, and unique design concept or intended use. The environmental matrix SRMs include air particulate matter, marine sediment, mussel tissue, and human serum with the focus on contaminants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), chlorinated pesticides, and polybrominated diphenyl ethers (PBDEs). Human serum and plasma SRMs for clinical diagnostic markers including vitamin D metabolites represent clinical analysis, whereas infant formula, multivitamin/multielement tablets, and Ginkgo biloba constitute the food and dietary supplement matrices on the list. Each of the SRMs on the Top Ten list is discussed relative to the selection criteria and significance of the material, and several overall lessons learned are summarized.

Improving Health Risk Assessment as a Basis for Public Health Decisions in the 21st Century.

One-fifth of the way through the 21st century, a commonality of factors with those of the last 50 years may offer the opportunity to address unfinished business and current challenges. The recommendations include: (1) Resisting the tendency to oversimplify scientific assessments by reliance on single disciplines in lieu of clear weight-of-evidence expressions, and on single quantitative point estimates of health protective values for policy decisions; (2) Improving the separation of science and judgment in risk assessment through the use of clear expressions of the range of judgments that bracket protective quantitative levels for public health protection; (3) Use of comparative risk to achieve the greatest gains in health and the environment; and (4) Where applicable, reversal of the risk assessment and risk management steps to facilitate timely and substantive improvements in public health and the environment. Lessons learned and improvements in the risk assessment process are applied to the unprecedented challenges of the 21st century such as, pandemics and climate change. The beneficial application of the risk assessment and risk management paradigm to ensure timely research with consistency and transparency of assessments is presented. Institutions with mandated stability and leadership roles at the national and international levels are essential to ensure timely interdisciplinary scientific assessment at the interface with public policy as a basis for organized policy decisions, to meet time sensitive goals, and to inform the public.

Trends in Trust in the Sources of Health Information on E-Cigarettes Among US Adults, 2015-2017.

Objectives. To evaluate recent levels and trends in trust in sources of health information on e-cigarettes in the United States.Methods. We obtained data from nationally representative samples of adults in 2015 (n = 5389), 2016 (n = 5273), and 2017 (n = 5389) that reported trust in 13 sources of health information on e-cigarettes in the United States. We used weighted linear regression models to examine temporal trends in trust levels.Results. Doctors, health organizations, the Centers for Disease Control and Prevention (CDC), health experts and scientists, the National Institutes of Health (NIH), the Food and Drug Administration (FDA), and family and friends were trusted, whereas news media, e-cigarette users, social media, vape shop employees, and e-cigarette and cigarette companies were distrusted. From 2015 to 2017, trust significantly increased for CDC, FDA, health experts and scientists, and news media (Ps < .01). Trust also increased for NIH between 2016 and 2017 (P < .01).Conclusions. US adults trust public health sources and distrust entities with commercial interest in e-cigarettes. This suggests that evidence-based messaging and information on health effects of e-cigarettes from public health professionals can effectively counter e-cigarette promotion and improve public understanding about e-cigarettes.

Global Perspective on Careers in Environmental Toxicologic Pathology: The 2019 Society of Toxicologic Pathology Annual Symposium Lunchtime Career Development Session.

A wide range of career options is available globally in the environmental toxicologic pathology (ETP) arena including academia, government, contract research organizations, and the agrichemical/chemical industry. This small and specialized subset of toxicologic pathologists addresses the effects of contaminants and pollutants on human, animal, and ecological health (One Health). Veterinary students and pathology trainees are primarily exposed to diagnostic pathology and often have limited exposure to toxicologic pathology and even less so to the issues and opportunities in environmental toxicology. The speakers provided a brief overview of global opportunities in their work sector and personal perspectives of their careers in ETP. The following panel discussion provided an opportunity to discuss issues related to careers in this specialty.

Skin sensitization testing needs and data uses by US regulatory and research agencies.

United States regulatory and research agencies may rely upon skin sensitization test data to assess the sensitization hazards associated with dermal exposure to chemicals and products. These data are evaluated to ensure that such substances will not cause unreasonable adverse effects to human health when used appropriately. The US Consumer Product Safety Commission, the US Environmental Protection Agency, the US Food and Drug Administration, the Occupational Safety and Health Administration, the National Institute for Occupational Safety and Health, and the US Department of Defense are member agencies of the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM). ICCVAM seeks to identify opportunities for the use of non-animal replacements to satisfy these testing needs and requirements. This review identifies the standards, test guidelines, or guidance documents that are applicable to satisfy each of these agency's needs; the current use of animal testing and flexibility for using alternative methodologies; information needed from alternative tests to fulfill the needs for skin sensitization data; and whether data from non-animal alternative approaches are accepted by these US federal agencies.

Exploring current read-across applications and needs among selected U.S. Federal Agencies.

Read-across is a well-established data gap-filling technique applied for regulatory purposes. In US Environmental Protection Agency's New Chemicals Program under TSCA, read-across has been used extensively for decades, however the extent of application and acceptance of read-across among U.S. federal agencies is less clear. In an effort to build read-across capacity, raise awareness of the state of the science, and work towards a harmonization of read-across approaches across U.S. agencies, a new read-across workgroup was established under the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM). This is one of several ad hoc groups ICCVAM has convened to implement the ICCVAM Strategic Roadmap. In this article, we outline the charge and scope of the workgroup and summarize the current applications, tools used, and needs of the agencies represented on the workgroup for read-across. Of the agencies surveyed, the Environmental Protection Agency had the greatest experience in using read-across whereas other agencies indicated that they would benefit from gaining a perspective of the landscape of the tools and available guidance. Two practical case studies are also described to illustrate how the read-across approaches applied by two agencies vary on account of decision context.
