Microplastic ingestion by an aquatic ciliate: Functional response, modulation, and reduced population growth.

Microplastic particles are ubiquitous in aquatic environments and are considered a major threat to the large range of heterotrophic organisms that involuntarily consume them. However, there is current uncertainty around the mechanisms underpinning microplastic uptake by aquatic consumers and the consequences for both the fate of the microplastics and the growth potential of consumer populations. We performed a feeding experiment, exposing a model freshwater ciliate, Tetrahymena pyriformis, to six different microplastic concentrations and measured microplastic uptake and population growth over the course of several generations.

Translation of a longitudinal survey of veterans' well-being into action by a research-practice-policy partnership.

Introduction: Research-practice-policy partnerships are shifting the academic research paradigm toward collaboration and research-informed action at community and policy levels. In this case study, researchers partnered with philanthropic foundations to actualize data findings from a rigorous, longitudinal study.

Context: In 2016, a survey of post-9/11 military veterans began assessing veterans' well-being in key domains: health, vocation (education and employment), finances, and social relationships.

Ketamine's Altered States Meta-Analysis: The Relationship Between Psychomimetic and Clinical Effects With Focus in Depression.

Background: In recent years, there has been a significant focus on exploring the potential therapeutic impact of altered states of consciousness on treatment outcomes for mental illness, with the goal of enhancing therapeutic strategies and patient results.

Methods: This meta-analysis was designed to investigate the potential link between the psychomimetic effects of ketamine and clinical outcomes in mental health, which adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Results: Eleven studies were selected for meta-analysis, and the main result did not find a significant correlation between the psychoactive effects of ketamine and clinical outcomes either in mental illness (n = 11; n's = 27; r = 0.

Health-related social needs screening, reporting, and assistance in a large health system.

Background: National mandates require screening for and addressing health-related social needs (HRSNs) in healthcare settings. However, differences in HRSN screening process (i.e.

A Political-Economic Model of Community and Societal Health Resources: A 92-Country Global Analysis.

The quality and access to healthcare systems depend on community health resources, infrastructure, and funding; however, a significant disparity in these resources persists globally. The effectiveness of national health systems depends on a balanced approach to health spending, access to facilities and a skilled local health workforce. What accounts for country-level differences in those critical community and societal health resources? We proposed and tested a model that leverages political and socioeconomic factors to predict various health resources and services in countries.
