Early adversity increases risk for child mental health difficulties. Stressors in the home environment (e.g., parental mental illness, household socioeconomic challenges) may be particularly impactful. Attending out-of-home childcare may buffer or magnify negative effects of such exposures. Using a longitudinal observational design, we leveraged data from the NIH Environmental influences on Child Health Outcomes Program to test whether number of hours in childcare, defined as 1) any type of nonparental care and 2) center-based care specifically, was associated with child mental health, including via buffering or magnifying associations between early exposure to psychosocial and socioeconomic risks (age 0–3 years) and later internalizing and externalizing symptoms (age 3–5.5 years), in a diverse sample of N = 2,024 parent–child dyads. In linear regression models, childcare participation was not associated with mental health outcomes, nor did we observe an impact of childcare attendance on associations between risk exposures and symptoms. Psychosocial and socioeconomic risks had interactive effects on internalizing and externalizing symptoms. Overall, the findings did not indicate that childcare attendance positively or negatively influenced child mental health and suggested that psychosocial and socioeconomic adversity may need to be considered as separate exposures to understand child mental health risk in early life.

The March 2, 2022, United Nations Environment Assembly Resolution 5/14: “End plastic pollution: Toward an international legally binding instrument by 2024” provides an important path for addressing global plastic pollution, from monomer design and production through the value chain to the final fate of plastic products, including resource recovery. Of the goals set for this effort, simplifying the polymer and additive universe is among the most significant. One primary obstacle to resource recovery from plastic waste is polymer variability, which renders post-use plastic inherently waste-like. While simplification will not address microplastics and leaching of chemicals during use, these measures simplify the plastic universe and mitigate leakage which is critical to ensuring circular plastic use. This study provides a pathway for simplification of formulations through the elimination of problematic additives and revealing paths toward simplifying and reducing the variability in polymers, waste streams and pollution, while preserving critical uses. This study focuses on phenolic antioxidants to support this concept; however, these principles can be applied to other additive classes. The results show extensive duplication of chemical species with different trade names and the appearance of only minor changes to species with the intention of evergreening patents for improved marketability.

Children with fragile X syndrome (FXS) often avoid eye contact, a behavior that is potentially related to hyperarousal. Prior studies, however, have focused on between-person associations rather than coupling of within-person changes in gaze behaviors and arousal. In addition, there is debate about whether prompts to maintain eye contact are beneficial for individuals with FXS. In a study of young females (ages 6–16), we used eye tracking to assess gaze behavior and pupil dilation during social interactions in a group with FXS (n = 32) and a developmentally similar comparison group (n = 23). Participants engaged in semi-structured conversations with a female examiner during blocks with and without verbal prompts to maintain eye contact. We identified a social–behavioral and psychophysiological profile that is specific to females with FXS; this group exhibited lower mean levels of eye contact, significantly increased mean pupil dilation during conversations that included prompts to maintain eye contact, and showed stronger positive coupling between eye contact and pupil dilation. Our findings strengthen support for the perspective that gaze aversion in FXS reflects negative reinforcement of social avoidance behavior. We also found that behavioral skills training may improve eye contact, but maintaining eye contact appears to be physiologically taxing for females with FXS.

A crucial reckoning was initiated when the COVID-19 pandemic began to expose and intensify long-standing racial/ethnic health inequities, all while various sectors of society pursued racial justice reform. As a result, there has been a contextual shift towards broader recognition of systemic racism, and not race, as the shared foundational driver of both societal maladies. This confluence of issues is of particular relevance to Black populations disproportionately affected by the pandemic and racial injustice. In response, institutions have initiated diversity, equity, and inclusion (DEI) efforts as a way forward. This article considers how the dual pandemic climate of COVID-19-related health inequities and the racial justice movement could exacerbate the “time and effort tax” on Black faculty to engage in DEI efforts in academia and biomedicine. We discuss the impact of this “tax” on career advancement and well-being, and introduce an operational framework for considering the interconnected influence of systemic racism, the dual pandemics, and DEI work on the experience of Black faculty. If not meaningfully addressed, the “time and effort tax” could contribute to Black and other underrepresented minority faculty leaving academia and biomedicine – consequently, the very diversity, equity, and inclusion work meant to increase representation could decrease it.

OBJECTIVES/SPECIFIC AIMS: We aimed to develop an assay to measure new protein synthesis after Antisense Oligonucleotide treatment, which we hypothesized to be the earliest biochemical identification of RNA-targeting therapy efficacy. METHODS/STUDY POPULATION: We treated 2 transgenic animal models expressing proteins implicated in neurodegenerative disease: human tau protein (hTau) and human superoxide dismutase 1 (hSOD1), with ASO against these mRNA transcripts. Animals received isotope-labeled 13C6-Leucine via drinking water to label newly synthesized proteins. We assayed target protein synthesis and concentration after ASO treatment to determine the earliest identification of ASO target engagement. RESULTS/ANTICIPATED RESULTS: hTau ASO treatment in transgenic mice lowered hTau protein concentration 23 days post-treatment in cortex (95% CI: 0.05%–64.0% reduction). In the same tissue, we observed lowering of hTau protein synthesis as early as 13 days (95% CI: 29.4%–123%). In hSOD1 transgenic rats, we observed lowering of 13C6-leucine-labeled hSOD1 in the cerebrospinal fluid 30 days after ASO treatment compared with inactive ASO control (95% CI: 12.0%–48.4%). DISCUSSION/SIGNIFICANCE OF IMPACT: In progressive neurodegenerative diseases, it is crucial to develop measurements that identify treatment efficacy early to improve patient outcomes. These data support the use of stable isotope labeling of amino acids to measure new protein synthesis as an early pharmacodynamics measurement for therapies that target RNA and inhibit the translation of proteins.

The role of land values in the dairy industry of an urban-influenced region is investigated by estimating a dairy herd equation based on pooled cross-section and time-series data from counties in New Jersey, Pennsylvania, and New York. The use of cross-terms between hypothesized causal variables and a dummy variable capturing the effect of location allowed the estimation of the differences across states in the effects of milk, feed, and land prices. Results confirm the important role of rising land values in the decline of the dairy industry in the tri-state area, and suggest greater vulnerability of dairy enterprises in urban-influenced areas to rising adverse economic forces. The adverse effects of declining milk prices and higher land values are greatest in New Jersey. The results support the notion that programs such as price support, farmland preservation, farmland assessment, and right-to-farm may have to be maintained in order to retain dairy farms at the urban fringe, where land values are rising rapidly.

From computerized medical records to databases of pharmacological interactions and automated provisional EKG readings, the emergence of information technology has significantly altered the practice of medicine. Information technology has been widely used to enhance diagnosis and treatment and to improve communication between providers. The advent of the Internet also brings far-reaching implications for patient–physician communication, challenging physicians, patients, and policymakers to consider its impact on the delivery of medical care and the therapeutic relationship. A new set of practices by patients and physicians is unfolding in cyberspace, ranging from the use of e-mail to communicate between physicians and patients in an existing relationship to one-to-one consultations with an anonymous physician and ongoing online treatment, such as psychotherapy. These practices are emerging in both the for-profit and not-for-profit spheres.

The nutritional condition of children with human immunodeficiency virus (HIV) infection continues to be a problem both in developed and developing countries. HIV-infected children grow below normal standards in both height and weight when compared with HIV-exposed non-infected children. These patterns persist over time. It is possible that acute infectious episodes and increased HIV viral burden contribute to decrements in all growth variables. Potential aetiologies for abnormal growth include inadequate dietary intake, gastrointestinal malabsorption, increased energy utilization and psycho-social problems. It is likely that all these factors contribute to the growth problems of these children to some extent. With the development of protease inhibitor anti-retroviral therapy and highly-active anti-retroviral treatment regimens, children with HIV infection in developed countries are living longer with a chronic illness. New nutritional problems have arisen with the development of the fat redistribution syndrome or lipodystrophy. Emerging problems are now being recognized, with the development of insulin resistance and truncal obesity which may potentially lead to premature cardiovascular disease.

Responding to mounting public concern about the shift to managed care, legislation to grant patient protections has dominated the health policy agenda over the past two years. Although some policies, such as laws on maternity length of stay, can be easily dismissed as “body part by body part” micromanagement of medical practice, other initiatives offer substantive, new rights to patients across the spectrum of care. At both the state and the federal levels, the right of enrollees to appeal a denial of treatment or to file grievances about other plan decisions has emerged as a centerpiece of patient protection legislation. Grievance and appeal rights have been embraced as a way to empower patients, to enhance access to treatment, and to improve the quality of care by providing an external mechanism to review treatment denials.

On November 8, 1994, Oregon became the first state in the nation to legalize assisted suicide. Passage of Proposition 16 was a milestone in the campaign to make assisted suicide a legal option. The culmination of years of effort, the Oregon vote followed on the heels of failed referenda in California and Washington, and other unsuccessful attempts to enact state laws guaranteeing the right to suicide assistance. Indeed, in 1993, four states passed laws strengthening or clarifying their ban against assisted suicide. No doubt, Proposition 16 is likely to renew the effort to legalize assisted suicide at the state level.

The battle over assisted suicide is also unfolding in the courts. Litigation challenging Proposition 16 on the grounds that it violates the equal protection clause is ongoing in Oregon. More significantly, three cases, two in federal courts and one in Michigan state court, have been brought to establish assisted suicide as a constitutionally protected right.

On June 25,1990, seven years after Nancy Cruzan lapsed into permanent unconsciousness following a car accident, the United States Supreme Court handed down its landmark decision in Cruzan v. Director, Missouri Department of Health. The decision provided the Court's first ruling on the right to forgo life-sustaining treatment, addressing both the right of individuals to decide for themselves and the right of family members to decide on their behalf.

Inextricably linked to the Court's holding on individual rights were questions about the authority and responsibility of each state to fashion policy for treatment decisions on behalf of incompetent patients. The Cruzun case presented an opportunity for the Court to comment upon and reshape the patchwork of laws that define the right to decide about life-sustaining treatment in states across the country.

The issuance of do-not-resuscitate orders was one of the first dilemmas scrutinized by lawyers, health care professionals and philosophers in the field of bioethics. In 1983, the President's Commission articulated the basic principles that should guide decisions about CPR: respect for the choices of patients capable of deciding for themselves, recognition of family members as appropriate surrogates for decisionally incapable patients and the importance of an open dialogue with the physician as a predicate to informed consent.

Six years have passed since the President's Commission issued its landmark report. More than a decade of discussion and written commentary has clarified the ethical and social questions presented by resuscitation decisions. In many states, judicial decisions and legislation have addressed some of the legal uncertainties associated with do-not-resuscitate (DNR) orders. Nonetheless, the gulf between recognized ethical principles and clinical practice remains broad and resistant to change. Nowhere is this gap more evident than in decisions about cardiopulmonary resuscitation (CPR) for competent patients.
