Bisphenol S (BPS) is a contaminant of emerging concern, its exposure and phytotoxicity towards plants, however, is scarce. This study aimed at revealing the BPS translocation in plants and phytotoxicity in the presence of Polystyrene (PS) microplastics. Results found that BPS and PS showed no effect on plant growth, indicating the tolerance of plants towards BPS and PS co-contamination. In addition, plants enriched BPS from soil, and a major part of absorbed BPS was accumulated in roots, as supported by the higher BCF value in roots compared with leaves. Besides, the low TF (<1) suggested the capacity of plants to accumulate BPS in roots, and less translocation to leaves. PS negatively affected the translocation of BPS in plants. PS with large size (5 μm) also increased the distribution of BPS in organelles. Exposure risk assessment suggested low concern of BPS carried in plants to human health. This study underlines the bioaccumulation of BPS in plants, and the effects of PS in the translocation process.

When encountering adverse environmental conditions, some holothurians can eject their internal organs in a process called evisceration. As global warming intensified, eviscerated and intact sea cucumbers both experience heat stress, but how they performed was uncertain. We constructed 24 metabolomics profiles to reveal the metabolite changes of eviscerated and intact sea cucumbers under normal and high temperature conditions, respectively. Carboxylic acids and fatty acyls were the most abundant metabolic categories in evisceration and heat stress treatments, respectively. Neural transduction was involved in sea cucumber evisceration and stress response, and the commonly enriched pathway was "neuroactive ligand-receptor interaction". Lipid metabolism in eviscerated sea cucumbers differed from those of intact individuals and was more seriously affected by heat stress. Choline is a key metabolite for revealing the evisceration mechanism. Our results contribute to understanding the mechanisms of evisceration in sea cucumbers, and how sea cucumbers might respond to increasingly warming ocean conditions.

Provider Perspectives on HIV Pre-Exposure Prophylaxis Service Disruptions and Adaptations During the COVID-19 Pandemic in Baltimore, Maryland: A Qualitative Study.

AIDS Patient Care STDS 2022 Aug;36(8):313-320

Department of Health, Behavior, and Society, Bloomberg School of Public Health, Johns Hopkins University, Baltimore, Maryland, USA.

The COVID-19 pandemic continues driving unprecedented disruptions to health care provision, including HIV pre-exposure prophylaxis (PrEP) services. We explored service provider experiences promoting and prescribing PrEP to marginalized populations during the COVID-19 pandemic in Baltimore, Maryland. In February to April 2021, we facilitated four virtual focus group discussions with 20 PrEP providers, representing various professional cadres and practice settings. Employing an iterative, team-based thematic analysis, we identified salient enablers and constraints to PrEP promotion, initiation, and maintenance in the COVID-19 era, along with innovative adaptations to PrEP service delivery. Discussants described attenuated demands for PrEP early in the pandemic, exemplified by high PrEP discontinuation rates. This was attributed to changes in clients' sexual behaviors and shifting priorities, including caregiving responsibilities, during the pandemic. Substantial systems-level disruptions impacting PrEP provision were identified, including outreach service suspension, personnel shortages, and facility restrictions on face-to-face visits. Providers emphasized that these disruptions, though occurring early in the pandemic, had protracted impacts on PrEP accessibility. The transition to telemedicine rendered health care services, including PrEP, more accessible/convenient to some clients and expeditious to providers. However, structural barriers to telehealth engagement (telephone/internet access), coupled with limitations of the virtual care environment (difficulty establishing rapport), impeded efforts to equitably promote and prescribe PrEP. Expanding the PrEP outreach workforce and availing alternatives to telemedicine (e.g., community-based PrEP provision, specimen self-collection) could facilitate PrEP care continuity, especially as COVID-19 transitions from an acute to a protracted health crisis.
