AI Article Synopsis

  • The rise of plastic pollution is a serious global issue that poses both environmental and health risks, particularly due to microplastics (MPs) and nanoplastics (NPs) released from degrading plastics.
  • Humans are regularly exposed to these tiny particles through ingestion, inhalation, and skin contact, leading to potential health impacts, especially in vital systems like cardiovascular, nervous, reproductive, and digestive systems.
  • This review compiles the latest research on the toxic effects of micro- and nanoplastics in human health, aiming to increase awareness and support the development of strategies to combat this ongoing plastic crisis.

Article Abstract

The escalation of plastic pollution represents a global environmental and health problem. Important toxic effects have been attributed to the increasing diffusion of microplastics (MPs) and nanoplastics (NPs) derived from the degradation of plastics. These particles have been ubiquitously observed in the environment, with humans being continuously exposed via ingestion, inhalation and skin contact. Nonetheless, the cellular homeostasis imbalance induced by micro- and nano- plastics (MNPs) in human health has been only recently shown, while most evidence and molecular mechanisms derived from studies and models. To date, the majority of available results testified the accumulation of MNPs in the cardiovascular, nervous, reproductive and digestive systems, and recently clear evidence about cardiovascular toxic effects of MNPs has been provided in humans. In this context, this review aims to provide a comprehensive update about the most recent studies reporting the effects of MNPs in different models, focusing on the available evidence in the main areas of study related to human health. Hopefully, this review will contribute to raise awareness about the toxicity and oxidative alteration exerted by MNPs, supporting the elaboration of new strategies to counteract plastic pandemics.

Background: Anxiety commonly affects older individuals with negative consequences on various physical and motor performances such as balance. When coupled with age-related muscular strength loss, the effects on the ability to perform daily tasks could be particularly detrimental, particularly in older women who are more susceptible to anxiety, muscular strength losses and falls. The study aimed to verify the effects of anxiety on balance performance in relation to muscular strength level in healthy older women.

Patients in need of a kidney transplant have the option of receiving a kidney from a living donor or a deceased donor. Patients in the United States who do not have an available living donor typically wait on the deceased donor waiting list for an average of three to five years, although some patients may wait longer. The waiting list is very complex and intended to allocate kidneys in a fair and equitable manner.
