Oxygen saturation in healthy-term neonates at high altitude: A multisite prospective study.

Objectives: To determine oxygen saturation (SpO) values and their variability in healthy-term neonates at high altitude.

Methods: In a prospective multisite, non-randomized blinded study, we performed SpO measurements in healthy neonates admitted to postnatal wards and followed up in Public Health Nurse Clinics (PHNC) in Calgary, Alberta, Canada. We recruited healthy-term neonates (≥37 weeks) between 6 and 24 h of age.

Therapeutic hypothermia success for hypoxic-ischaemic encephalopathy in Latin America: Eight-year experience in EpicLatino Neonatal Network.

Aim: A study reported that therapeutic hypothermia (TH) did not reduce the combined prognosis of mortality and disability at 18 months, in low- and middle-income countries for patients with hypoxic ischaemic encephalopathy (HIE) who received TH, suggesting its no implementation in these regions. We described characteristics, mortality, and neurological response before and after the use of TH in newborns with HIE within the EpicLatino Neonatal Network (ENN) and described the population of infants with HIE treated and not treated with TH.

Methods: Data were collected from 2015 to 2022 for patients with HIE.

Assessing the long-term adverse effects of aluminium nanoparticles on freshwater phytoplankton using isolated-species and microalgal communities.

The physicochemical properties of aluminum oxide nanoparticles (AlO-NPs or AlNPs) allow them to remain suspended in water for extended periods. Despite this, AlNPs are one of the least studied types of metal nanoparticles and pose a significant risk to aquatic ecosystems. Therefore, it is essential to understand the toxic mechanisms of AlNPs on microalgae and cyanobacteria, as they can have adverse effects on the entire aquatic food web.

Influence of polyethylene-type microplastics on long-term exposure to heavy metals in freshwater phytoplankton.

The use of plastic materials has brought about significant social benefits but has also led to negative consequences, particularly their accumulation in aquatic environments. Studies have shown that small plastic particles, known as microplastics (MPs), can carry various harmful pollutants, such as heavy metals (HMs). Therefore, the aim of this research is to investigate the impact of polyethylene-type MPs on the long-term exposure of different HMs on freshwater microalgae Scenedesmus armatus and cyanobacteria Microcystis aeruginosa, in both isolated cultures and phytoplanktonic community conditions.
