Adverse drug reaction as cause of hospital admission of elderly people: a pilot study

The objective of this study was to estimate the prevalence of adverse drug reactions (ADR) related to hospital admission of elderly people, identifying the use of potentially inappropriate medication (PIM), the ADR and the risk factors associated with the hospitalization. A cross-sectional study was conducted in a private hospital of São Paulo State, Brazil. All patients aged ≥ 60 years, admitted in the general practice ward in May 2006 were interviewed about the drugs used and the symptoms/complaints that resulted in hospitalization. More than a half (54.5 %) of elderly hospitalizations were related with ADR. The therapeutic classes involved with ADR were: cardiovascular (37.7 %), central nervous (34.6 %) and respiratory (5.7 %). The ADR observed were disorders in circulatory (28.4 %), digestive (20.0 %) and respiratory (18.9 %) tracts. 27 elderly had made PIM and in 20 of them this was the cause of hospitalization. Polypharmacy was an ADR risk factor (p = 0.021).These data allows the healthcare professionals upgrade, qualifying them in pharmcovigilance.

Evidence of defect-mediated magnetic coupling on hydrogenated Co-doped ZnO

Hydrogenated bulk Zn1-xCoxO samples were synthesized via standard solid-state reaction route with Co molar concentrations up to 15 at.%. Magnetic characterization demonstrates a room temperature ferromagnetic behavior associated to a paramagnetic Curie-Weiss component. Detailed microstructural analysis was carried out to exclude the presence of extrinsic sources of ferromagnetism. The magnetization increases linearly as a function of Co concentration. Hall measurements reveal an insulating character for the whole set of samples. In this context, the defect mediated magnetic coupling between the Co atoms under the scope of the bound magnetic polarons model is used to interpret the observed room temperature ferromagnetism. © 2012 Elsevier B.V.

NN -> NN pi(+) reaction near threshold in a chiral power counting approach

Power-counting arguments are used to organize the interactions contributing to the NN-->d pi,pn pi reactions near threshold. We estimate the contributions from the three formally leading mechanisms: the Weinberg-Tomozawa (WT) term, the impulse term, and the Delta-excitation mechanism. Subleading but potentially large mechanisms, including S-wave pion rescattering, the Galilean correction to the WT term, and short-ranged contributions are also examined. The WT term is shown to be numerically the largest, and the other contributions are found to approximately cancel. Similarly to the reaction pp-->pp pi(0), the computed cross sections are considerably smaller than the data. We discuss possible origins of this discrepancy.
