Testing the effectiveness of the exercise plus program in older women post-hip fracture

Background: Exercise is an important strategy with potential to improve recovery in older adults following a hip fracture.Purpose: The purpose of this study was to test the impact of a self-efficacy based intervention, the Exercise Plus Program, and the different components of the intervention, on self-efficacy, outcome expectations, and exercise behavior among older women post-hip fracture.Methods: Participants were randomized to one of four groups: exercise plus, exercise only, plus only (i.e., motivation), or routine care. Data collection was done at baseline (within 22 days of fracture), 2, 6, and 12 months post-hip fracture.Results: A total of 209 women were recruited with an average age of 81.0 years (SD=6.9). The majority was White (97.1%), was widowed (57.2%), and had a high school education (66.7%). Generalized Estimating Equations were used to perform repeated measures analyses. No differences in trajectories of recovery were observed for self-efficacy or outcome expectations. A statistically significant difference in the overall trajectory of time in exercise was seen (p<.001), with more time spent exercising in all three treatment groups.Conclusions: The study demonstrated that it was possible to engage these women in a home-based exercise program and that the plus only, exercise only, and the exercise plus groups all increased exercise. Support for this project was provided by National Institute on Aging grants R37 AG09901, R01-AG18668, R01 AG17082, and the Claude D. Pepper Older Americans Independence Center P60-AG12583.     

Perceived value of nursing certification--summary of a national survey.

The American Board of Nursing Specialties (ABNS) conducted a survey to determine the value professional nurses place on nursing certification as well as barriers to certification. This article presents an overview of the survey results in general and specifically the views of nephrology nurse participants.     

Subjective work noise: A major risk factor in myocardial infarction

Summary The relationship between subjective work noise exposure and the risk of myocardial infarction (MI) was assessed in a population based casecontrol study. 395 MI patients (31–65 years) were compared to 2148 controls from a random population sample with the same age/sex distribution. The relative risk (RR) for MI—adjusted for control variables (smoking, age, social status, etc.)—was found to increase significantly and steadily with noise category. Subjective work noise exposure was the second greatest risk factor for MI after smoking. Possible bias due to overreporting of subjective noise exposure is discussed. Interdisciplinary studies on the relationship between cardiovascular diseases and workrelated stressors including subjective and objective noise assessment are needed to quantify the risk of MI due to work noise.

Zusammenfassung In einer bevölkerungsbezogenen Fall-Kontroll-Studie wurde der Zusammenhang zwischen der subjektiven Arbeitslärmbelastung und dem Herzinfarktrisiko untersucht. 395 Herzinfarktpatienten im Alter von 31 bis 65 Jahren wurden mit 2148 Kontrollpersonen aus einer Zufallsstichprobe mit gleicher Alters- und Geschlechtsverteilung verglichen. Das relative Risiko für Herzinfarkt—adjustiert bezüglich mehrerer Einflussvariablen wie Rauchen, Alter, Sozialstatus usw.—stieg signifikant und monoton mit der Arbeitslärmbelastung an. Die subjektive Arbeitslärmbelastung erwies sich als der zweitwichtigste Risikofaktor für Herzinfarkt nach dem Rauchen. Mögliche Fehler wie z.B. Überbewertung der subjektiven Lärmbelastung werden diskutiert. Interdisziplinäre Studien zum Zusammenhang zwischen kardiovaskulären Erkrankungen und arbeitsplatzbezogenen Stressoren mit Erfassung der subjektiven und der objektiven Lärmbelastung sind notwendig, um das Herzinfarktrisiko durch Arbeitslärm zu quantifizieren.

Résumé Le rapport entre la perception subjective de bruit gênant et le risque d'infarctus du myocarde (IM) fait l'objet d'une étude comparative portant sur 395 malades (IM) âgés de 31 à 65 ans et 2148 cas témoins sortis d'un sondage aléatoire parmi la population générale tout en assurant la même distribution d'âge et de sexe. II s'avère que—après la rectification exigée par les variables telles que consommation de tabac, âge, couche sociale, etc.—le risque relatif (RR) de IM augmente de manière significative et constante avec le gêne causé par le bruit au lieu de travail. Pour le IM, la perception subjective du bruit vécu au lieu de travail est le deuxième facteur de risque, son importance n'étant dépassée que par le tabagisme. Les auteurs discutent l'incidence possible d'une notification exagérée de bruit gênant. Afin de calculer le risque d' IM attributable au bruit perçu au lieu de travail, des études interdisciplinaires devraient être réalisées pour examiner les liens entre les maladies cardiovasculaires et les stresseurs liés au travail, y compris l'évaluation subjective et objective du bruit.

     

Therapy of refractory/relapsed acute myeloid leukemia and blast crisis of chronic myeloid leukemia with the combination of cytosine arabinoside,tetrahydrouridine, and carboplatin

Summary Eight patients, of whom four had acute myeloid leukemia (AML) and four had chronic myeloid leukemia (CML) blast crisis, were treated with a combination of cytosine arabinoside (ARA-C: 1,600 mg/m² in three patients, 1,200 mg/m² in five patients), tetrahydrouridine (THU: 2,800 mg/m² in two patients, 2,646 mg/m² in one patient, 2,100 mg/m² in five patients), and carboplatin (900 mg/m² in four patients, 720 mg/m² in one patient, 450 mg/m² in three patients). As a result of this treatment, five of the eight patients became aplastic. Two of the four patients with CML blast crisis reverted to the chronic phase and two of the four patients with acute nonlymphocytic leukemia (ANLL) attained a remission (one partial remission and one complete remission). The major toxicities included myelosuppression, unacceptable hepatotoxicity, and diarrhea. Pharmacokinetics studies revealed that the addition of carboplatin did not significantly change the disposition of ARA-C. ARA-C levels were not significantly changed in comparison with those obtained in a prior study of ARA-C with THU (ARA-C plasma levels at 3 h, 2630±1170 ng/ml).Supported by the Don Monti Memorial Research Foundation     

Amplification of the c-erbB oncogene is associated with malignancy in primary tumours of neuroepithelial tissue

Summary In various primary brain tumours of neuroepithelial tissue recombinant DNA techniques were used to demonstrate changes of the epidermal growth factor receptor gene, which is homologous to the c-erbB oncogene. Twenty-one of 40 grade III/IV tumours, but only 1 of 16 grade I/II tumours were found to contain amplified and/or rearranged c-erbB sequences. This highly significant difference suggest that c-erbB amplification, rearrangement, or both, are important steps in malignant transformation in a subset of patients with neuroepithelial tumours.
