Origin of the giant magnetic moments of Fe impurities on and in Cs films

To explore the origin of the observed giant magnetic moments ($\sim 7 \mu_B$) of Fe impurities on the surface and in the bulk of Cs films, we have performed the relativistic LSDA + U calculations using the linearized muffin-tin orbital (LMTO) band method. We have found that Fe impurities in Cs behave differently from those in noble metals or in Pd. Whereas the induced spin polarization of Cs atoms is negligible, the Fe ion itself is found to be the source of the giant magnetic moment. The 3d electrons of Fe in Cs are localized as the 4f electrons in rare-earth ions so that the orbital magnetic moment becomes as large as the spin magnetic moment. The calculated total magnetic moment of $M = 6.43 \mu_B$, which comes mainly from Fe ion, is close to the experimentally observed value.Comment: 4 pages including 3 figures and 1 table.

Social Support and Self-Care of Patients with Heart Failure

Background Social support can influence treatment adherence of patients with chronic illnesses, which may explain the positive effects of social support on heart failure (HF) outcomes. Purpose To investigate the effects of social support among patients with HF, we examined whether aspects of social support were associated with self-care, including medication adherence, dietary adherence, and HF symptom monitoring functions. Methods We recruited 74 patients with HF from cardiology clinics of a Veterans Affairs Medical Center and a university-affiliated hospital, and tested the relationships between social support and the patients\u27 self-care. Results Consistent with previous research in older adults, family members, especially spouses, were often involved in the medical care of patients with chronic HF and provided a range of levels of support to patients. Self-care was generally poor, as measured across several self-care domains. Perceived social support was moderately associated with relatively better self-reported medication and dietary adherence, and other aspects of self-care such as daily weighing. Conclusions These findings suggest that a relatively higher level of self-care is an important correlate of social support and may explain how social support influences HF outcomes. This study also suggests that family members should play a greater part in clinical care focused on improving self-care

Clinical Exacerbations as a Surrogate End Point in Heart Failure Research

Background We examined the utility of an index of clinical exacerbations of heart failure (HF) as a surrogate measure of outcome for use in modestly sized clinical trials and observational studies. Methods Electronic records of 189 outpatients with HF in a US Veterans Affairs Medical Center were examined over a 2- to 3-year period. Data collected included patient characteristics, clinical exacerbations of HF, hospitalizations, and deaths. Subsets of patient were also assessed for HF-related level of functioning. Results Episodes of clinical exacerbation could be detected reliably (kappa = .83). An index of episodes (number of episodes divided by the time in years) was associated with lower quality of life, higher functional class, increased rate of HF hospitalization, poorer exercise tolerance, and up to 30% increased risk of mortality across 2 years. Conclusions The index of HF exacerbations is potentially a useful surrogate end point for use in clinical HF research

Psychiatric Comorbidity and Greater Hospitalization Risk, Longer Length of Stay, and Higher Hospitalization Costs in Older Adults with Heart Failure

OBJECTIVES: To explore associations between psychiatric comorbidity and rehospitalization risk, length of hospitalization, and costs. DESIGN: Cross‐sectional study of 1‐year hospital administrative data. SETTING: Claims‐based study of older adults hospitalized in the United States. PARTICIPANTS: Twenty‐one thousand four hundred twenty‐nine patients from a 5% national random sample of U.S. Medicare beneficiaries aged 65 and older, with at least one acute care hospitalization in 1999 with a Diagnostic‐Related Group of congestive heart failure. MEASUREMENTS: The number of hospitalizations, mean length of hospital stay, and total hospitalization costs in calendar year 1999. RESULTS: Overall, 15.8% of patients hospitalized for heart failure (HF) had a coded psychiatric comorbidity; the most commonly coded comorbid psychiatric disorder was depression (8.5% of the sample). Most forms of psychiatric comorbidity were associated with greater inpatient utilization, including risk of additional hospitalizations, days of stay, and hospitalization charges. Additional hospitalization costs associated with psychiatric comorbidity ranged up to $7,763, and additional days length of stay ranged up to 1.4 days. CONCLUSION: Psychiatric comorbidity appears in a significant minority of patients hospitalized for HF and may affect their clinical and economic outcomes. The associations between psychiatric comorbidity and use of inpatient care are likely to be an underestimate, because psychiatric illness is known to be underdetected in older adults and in hospitalized medical patients
