From 2D kaolinite to 3D amorphous cement.

Kaolinite is a single 2D layer of kaolin or metakaolin (MK), common clays that can be characterized as layered 3D materials. We show that because of its chemical composition, kaolinite can be converted into an amorphous 3D material by chemical means. This dimensional transformation is possible due to the large surface to volume ratio and chemical reactivity of kaolinite.

Hospital-level volume in extracorporeal membrane oxygenation cases and death or disability at 6 months.

Objective: Extracorporeal membrane oxygenation (ECMO) is a high-risk procedure with significant morbidity and mortality and there is an uncertain volume-outcome relationship, especially regarding long-term functional outcomes. The aim of this study was to examine the association between ECMO centre volume and long-term death and disability outcomes.

Design Setting And Participants: This is a registry-embedded observational cohort study.

The Psychometric Properties of the EuroQol 5D Five Level in Survivors of Critical Illness.

Objectives: The EuroQol 5D five level (EQ-5D-5L) instrument is a standardized measure of health-related quality of life and is routinely used in survivors of critical illness. However, information on its psychometric properties and minimal clinically important difference (MCID) in this patient group is lacking.

Design: Secondary analysis of data from the previously published PREDICT (a registry in critically ill patients to determine predictors of disability-free survival) study, a prospective, multicenter cohort study.

Lacustrine sedimentation patterns at the Northern Antarctic Peninsula and surroundings as a response to late Holocene and Modern Climate changes.

The Northern Antarctic Peninsula (NAP) and the West Antarctic Ice Sheet (WAIS) are likely to respond rapidly to climate changes by increasing the collapse of peripheral ice shelves and the number of days above 0 °C. These facts make this region a representative hotspot of the global sea level rise and the location of one of the global climate tipping points (thresholds in the Earth system whose changes may become irreversible, if exceeded). Understanding the climate evolution of the NAP, based on past evidences, may help infer its future scenario.

The Peritubercle Lucency Sign as a Considerable Predictive Factor for Contralateral Hip Slippage in Unilateral Slipped Capital Femoral Epiphysis Cases.

 To determine whether the radiographic parameter at the epiphyseal tubercle region (peritubercle lucency sign) on the unaffected side can predict slipped capital femoral epiphysis (SCFE).  We retrospectively reviewed patients who received an initial diagnosis of unilateral SCFE between 1995 and 2020 at a pediatric hospital in a Brazilian state's capital. The patients were monitored for at least 18 months.
