Social isolation and depression predict 12-month outcomes in the "waiting for a new heart study".

2009

Identification of modifiable psychosocial characteristics related to survival of heart transplant (HTx) candidates is needed to prevent clinical deterioration and improve prognosis.A multi-site, prospective study was conducted with 318 HTx candidates (18% female, 82% male; 53 +/- 11 years of age) newly listed at 17 hospitals in Germany and Austria. Baseline demographic and psychosocial characteristics were assessed by questionnaires. Indicators of disease severity (Heart Failure Survival Score, creatinine, cardiac index) and 12-month outcomes (death, high-urgency HTx, elective HTx, de-listing due to deterioration or improvement) were provided by Eurotransplant.By 12 months, 33 patients died…

Finely tuned nickel complexes as highly active catalysts affording branched polyethylene of high molecular weight: 1-(2,6-Dibenzhydryl-4- methoxyphen…

Abstract A series of unsymmetrical 1,2-bis(imino)acenaphthenenickel(II) halides containing N-2,6-dibenzhydryl-4-methoxyphenyl – a single bulky group with adjusted electron donating properties – has been synthesized and characterized. These compounds adopt distorted tetrahedral geometry and their 1H NMR spectra show the paramagnetically shifted peaks. On activation with a low amount of Et2AlCl or ethylaluminum sesquichloride (EASC), these nickel complexes display high activity in ethylene polymerization, yielding the polyethylene of high molecular weight. They are also stable at elevated temperature; superb activity of 2.51 × 106 g of PE (mol of Ni)−1 h−1 can be attained at 90 °C. The result…
