Purpose: To determine whether prophylactic caffeine and ibuprofen, which have been shown to have vascular endothelial growth factor-modulating properties in other contexts, have a detectable effect on the incidence of severe retinopathy of prematurity (ROP) when administered in extremely low birth weight infants during the first 48 hours of life.
Methods: In this retrospective cohort study, the incidence and severity of ROP with respect to total exposure to caffeine and ibuprofen were assessed. The effect of oxygen exposure at 28 days' postnatal age (PNA) and 36 weeks' corrected gestational age (GA) was also studied.
Results: A total of 109 infants were included; of these, complete data were available for 93 infants (87%), of whom 18 (19%) had severe ROP (ETROP type 1, or stage 3), and 75 (81%) had mild-to-moderate ROP at final diagnosis. Infants with severe ROP had lower GA (P = 0.0006). Total caffeine and ibuprofen exposure did not vary with severity of ROP (P = 0.86 caffeine; P = 0.57 ibuprofen). Presence of oxygen at 28 days' PNA (P = 0.01) or 36 weeks' corrected GA varied significantly with ROP severity (P = 0.0005).
Conclusions: A relationship between prophylactic caffeine and ibuprofen exposure and severity of ROP could not be detected in our study cohort. Presence of oxygen at 28 days' PNA or 36 weeks' corrected GA was associated with ROP severity.

Multi-generational exposure of Daphnia magna to pharmaceuticals: Effects on colonization, reproduction, and habitat selection behavior.

The presence of pharmaceuticals in the aquatic environment is increasing due to their growing use for human health. Although most studies are based on short exposures to these contaminants, the present study has emerged from the need to study pharmaceuticals in aquatic organisms over a long-term exposure to understand any multi-generational chronic effects and alterations regarding habitat selection. Therefore, this study shows: (1) the ability of Daphnia magna to colonize environments contaminated with caffeine, ibuprofen and fluoxetine, and (2) the effect of these pharmaceuticals on reproduction and habitat selection (under two scenarios: with and without food) after a long-term exposure period of three generations.

Given the limited research on pharmaceuticals and personal care products (PPCPs) in the Wuhan section of the Yangtze River (WYR), this work investigated the distribution of 15 PPCPs in this region, assessed their ecological risks and annual fluxes. It was further to analyze the levels of indicator sucralose in the WYR to understand the sources of PPCPs. The results showed the average concentrations were 143.

Vegetated biofiltration system (VBS) is an effective green technology for urban stormwater and greywater treatment. However, VBS is yet to be optimised for effective treatment of wastewater, particularly if it contains trace organic chemicals (TrOCs). The effect of plant species has not been addressed under TrOC wastewater loading.

Microbial biotransformation of trace organic chemicals (TOrCs) is an essential process in wastewater treatment to eliminate environmental pollution. Understanding TOrC biotransformation mechanisms, especially at their original concentrations, is important to optimize treatment performance, whereas our current knowledge is limited. Here, we investigated the biotransformation of seven TOrCs by 24 model communities.

Due to global population growth and increased healthcare accessibility, pharmaceuticals and personal care products (PPCPs) are closely linked with human activities and have become new pollutants alongside some legacy priority pollutants, such as polycyclic aromatic hydrocarbons (PAHs). Although PPCPs have been detected in numerous river basins in recent years, a few researches have been carried out on their association with human activities. In this paper, the concentrations of PPCPs and toxicological data were compiled for over 25 representative watersheds in China in the past two decades from various sources, including PubMed, Elsevier and Springer.
