Department of Chemistry and Centre for Catalysis Research and Innovation, University of Ottawa, 30 Marie Curie, Ottawa, Ontario K1N 6N5, Canada.

Published: February 2014

The Ruppert-Prakash reagent (Me3SiCF3) is used to introduce difluorocarbene (CF2) and tetrafluoroethylene (TFE) ligands to cobalt(I) metal centres, whereby the TFE ligand is generated via [2+1] cycloaddition between [Co]=CF2 and CF2.

Article Synopsis
  • Preterm birth significantly impacts parents' mental health, and posttraumatic growth (PTG) can help them cope with this trauma, though research on PTG in this context is limited.
  • A study involving 160 parents in Shenzhen, China, found that most had low to medium PTG levels, with influences like older gestational age, higher Apgar scores, positive coping styles, and better social support correlating with higher PTG.
  • The findings highlight the importance of social support and effective coping mechanisms in fostering PTG among parents dealing with the challenges of having a preterm infant.

Background: The aim of this study was to examine the potential added value of including neuropsychiatric symptoms (NPS) in machine learning (ML) models, along with demographic features and Alzheimer's disease (AD) biomarkers, to predict decline or non-decline in global and domain-specific cognitive scores among community-dwelling older adults.

Objective: To evaluate the impact of adding NPS to AD biomarkers on ML model accuracy in predicting cognitive decline among older adults.

Methods: The study was conducted in the setting of the Mayo Clinic Study of Aging, including participants aged ≥ 50 years with information on demographics (i.

Background: Echocardiography is widely used to assess aortic stenosis (AS) but can yield inconsistent results, leading to uncertainty about AS severity and the need for further diagnostics. This retrospective study aimed to evaluate a novel echocardiography-based marker, the signal intensity coefficient (SIC), for its potential in accurately identifying and quantifying calcium in AS, enhancing noninvasive diagnostic methods.

Methods: Between May 2022 and October 2023, 112 cases of AS that were previously considered severe by echocardiography were retrospectively evaluated, as well as a group of 50 cases of mild or moderate AS, both at the Eastern Slovak Institute of Cardiovascular Diseases in Kosice, Slovakia.

The modern use of hydroxyurea for children with sickle cell anemia.

Over the past 40 years, the introduction and refinement of hydroxyurea therapy has led to remarkable progress for the care of individuals with sickle cell anemia (SCA). From initial small proof-of-principle studies to multi-center Phase 3 controlled clinical trials and then numerous open-label studies, the consistent benefits of once-daily oral hydroxyurea have been demonstrated across the lifespan. Elevated fetal hemoglobin (HbF) serves as the most important treatment response, as HbF delays sickle hemoglobin polymerization and reduces erythrocyte sickling.

A nomograph model for predicting the risk of diabetes nephropathy.

Int Urol Nephrol

January 2025

Medical College, Qinghai University, Xining, 810016, People's Republic of China.

Objective: Using machine learning to construct a prediction model for the risk of diabetes kidney disease (DKD) in the American diabetes population and evaluate its effect.

Methods: First, a dataset of five cycles from 2009 to 2018 was obtained from the National Health and Nutrition Examination Survey (NHANES) database, weighted and then standardized (with the study population in the United States), and the data were processed and randomly grouped using R software. Next, variable selection for DKD patients was conducted using Lasso regression, two-way stepwise iterative regression, and random forest methods.
