Mortality associated with stopping statins in the oldest-old - with and without ischemic heart disease.

The association between stopping statins and 1-year mortality in the general population of the oldest-old - with or without ischemic heart disease (IHD) - has been studied herein for the first time.This was a retrospective study. Included were all consecutive patients (n = 369) aged 80 years or more (mean age 87.

Systematic evaluation of activated carbon-FeO composites for removing and degrading emerging organic pollutants.

In this study, a comparative activity assessment of several activated carbon (AC) and AC-FeO composites was performed to evaluate their efficiency and versatility as Fenton-like catalysts. Although many studies have demonstrated the advantages of AC-based materials as Fenton-like catalysts, most have been developed using only one oxidant and/or one pollutant. Here, untreated (AC) and acid-treated AC (AC) iron-oxide composites were synthesized, characterized, and compared in terms of activity to bare AC using several oxidants and pollutants, the activation efficiency of hydrogen peroxide (HO) and ammonium persulfate ((NH)SO), and the subsequent oxidation extent and kinetics of bisphenol-A, atrazine, and carbamazepine by the AC-based materials were studied in depth.

Parent-Adolescent Communication Influences on Anxious and Depressive Symptoms in Early Adolescence.

The unique developmental changes and important role of parents during early adolescence warrants consideration of parent-adolescent communication, including open communication, co-problem-solving, and co-rumination, and its influences on adolescents' anxious and depressive symptoms. In this study, 400 early adolescents (M age = 12.49; 54% female) recruited from a middle school completed electronic questionnaires at two time points, 5 months apart.

Which laboratory malnutrition markers best predict 1-year mortality in hospitalized older adults?

Purpose: To study which laboratory malnutrition markers best predict 1-year mortality in the general population of hospitalized older adults as well as among patients at risk for malnutrition.

Methods: A historical prospective study. All older adults (age ≥ 65 years) hospitalized in one geriatric department during 9 months were included.

Synthetic 9-cis-beta-carotene inhibits photoreceptor degeneration in cultures of eye cups from rpe65rd12 mouse model of retinoid cycle defect.

The retinoid cycle enzymes regenerate the visual chromophore 11-cis retinal to enable vision. Mutations in the genes encoding the proteins of the retinoid cycle are the leading cause for recessively inherited retinal dystrophies such as retinitis pigmentosa, Leber congenital amaurosis, congenital cone-rod dystrophy and fundus albipunctatus. Currently there is no treatment for these blinding diseases.
