Noninvasive Ventilation or CPAP for Postextubation Support in Small Infants.

Background: Infants with a high risk of extubation failure are often treated with noninvasive ventilation (NIV) or CPAP, but data on the role of these support modalities following extubation are sparse. This report describes our experience using NIV or CPAP to support infants following extubation in our pediatric ICUs (PICUs).

Methods: We performed a retrospective study of children < 10 kg receiving postextubation NIV or CPAP in our PICUs.

Perspectives of Parents and Teachers on the Impact of the COVID-19 Pandemic on Children's Socio-Emotional Well-Being.

The negative impacts of COVID 19 on children's holistic development have been reported by researchers around the world. This qualitative study explored teachers' and parents' perspectives on the impact of physical/social distancing and school closure policies on children's socioemotional development. The study was conducted in fall 2020.

Carbon monoxide levels in households using coal-briquette fuelled stoves exceed WHO air quality guidelines in Ulaanbaatar, Mongolia.

In 2019, a domestic raw coal ban (RCB) was introduced in Ulaanbaatar, Mongolia. Coal-briquettes have since been promoted in Ger district households, however implications for carbon monoxide (CO) exposure remains uncertain. We obtained 48-hour indoor CO concentrations in 23 Ger district households and compared these to 10 raw-coal households.

Citizen science reveals unexpected solute patterns in semiarid river networks.

Human modification of water and nutrient flows has resulted in widespread degradation of aquatic ecosystems. The resulting global water crisis causes millions of deaths and trillions of USD in economic damages annually. Semiarid regions have been disproportionately affected because of high relative water demand and pollution.

Tundra wildfire triggers sustained lateral nutrient loss in Alaskan Arctic.

Climate change is creating widespread ecosystem disturbance across the permafrost zone, including a rapid increase in the extent and severity of tundra wildfire. The expansion of this previously rare disturbance has unknown consequences for lateral nutrient flux from terrestrial to aquatic environments. Lateral loss of nutrients could reduce carbon uptake and slow recovery of already nutrient-limited tundra ecosystems.

Characterization of permissive and non-permissive peptide insertion sites in chloramphenicol acetyltransferase.

The growing prevalence of antibiotic resistance in numerous pathogenic bacteria is a major public health concern and urgently requires the development of new therapeutic approaches. Multidrug resistant species that remain sensitive to chloramphenicol (CAM) treatment have engendered renewed interest in using this drug as a modern day antimicrobial agent. High-level resistance to CAM commonly is mediated by chloramphenicol acetyltransferase (CAT) which catalyzes the acetylation of CAM and renders the drug inactive.

An overview of respiratory problems in children with Down's syndrome.

Respiratory disease is a common cause of morbidity and mortality in children with Down's syndrome (DS). Causes range from those problems common to many children with DS, such as a narrow airway or impaired immunity, to rare structural lesions, such as tracheal bronchus. Additionally, other organ systems or extrinsic factors may play a role.

The Subjective Experiences of Psychosis Scale (SEPS): psychometric evaluation of a scale to assess outcome in psychosis.

Background: A range of outcome measures has been developed to assess psychotic symptoms. Many of these are observer based assessments which rate the presence and severity of broad symptom types. There is a need for service-user generated multi-dimensional scales to assess psychosis.
