The Influence of Mutuality on Self-Care in Heart Failure Patients and Caregivers: A Dyadic Analysis
No full textMutuality in patient–caregiver dyad may improve heart failure (HF) patient self-care and caregiver contribution to self-care, but literature is scarce. We evaluated the influence of mutuality and its dimensions on patient–caregiver dyad self-care. A sample of 366 HF patient–caregiver dyads was enrolled. The Actor–Partner Interdependence Model was used to identify the influence of individual patient and caregiver mutuality on their own self-care (actor effect) and on partner self-care (partner effect). The total mutuality score had an actor effect on patient self-care maintenance (i.e., behaviors aimed at maintaining HF stability) and on patient and caregiver self-care confidence. Total score of patient mutuality also had a partner effect on caregiver self-care management (i.e., responses to symptoms of HF exacerbation). Specific mutuality dimensions had different actor and partner effects on patient and caregiver self-care. Interventions to improve mutuality in HF patient–caregiver dyads may influence patient self-care and caregiver contribution to self-care
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Validity and reliability of the mutuality scale in heart failure patient and caregiver dyads
No full textGlucose regulates diacylglycerol intracellular levels and protein kinase C activity by modulating diacylglycerol-kinase subcellular localization.
No full textAlthough chronic hyperglycemia reduces insulin sensitivity and leads to impaired glucose utilization, short term exposure to high glucose causes cellular responses positively regulating its own metabolism. We show that exposure of L6 myotubes overexpressing human insulin receptors to 25 mm glucose for 5 min decreased the intracellular levels of diacylglycerol (DAG). This was paralleled by transient activation of diacylglycerol kinase (DGK) and of insulin receptor signaling. Following 30-min exposure, however, both DAG levels and DGK activity returned close to basal levels. Moreover, the acute effect of glucose on DAG removal was inhibited by >85% by the DGK inhibitor R59949. DGK inhibition was also accompanied by increased protein kinase C-alpha (PKCalpha) activity, reduced glucose-induced insulin receptor activation, and GLUT4 translocation. Glucose exposure transiently redistributed DGK isoforms alpha and delta, from the prevalent cytosolic localization to the plasma membrane fraction. However, antisense silencing of DGKdelta, but not of DGKalpha expression, was sufficient to prevent the effect of high glucose on PKCalpha activity, insulin receptor signaling, and glucose uptake. Thus, the short term exposure of skeletal muscle cells to glucose causes a rapid induction of DGK, followed by a reduction of PKCalpha activity and transactivation of the insulin receptor signaling. The latter may mediate, at least in part, glucose induction of its own metabolism
Self-care in heart failure patients: major results of a 7-year research program in Italy
No full textSelf-care improves patients’ outcomes in heart failure (HF). In this article we report the main results of a 7-year research program conducted in Italy. First, we established validity and reliability of the Self-Care of HF Index v.6.2 and the Caregiver Contribution to Self-Care of HF Index in the Italian population. Second, we tested the situation-specific theory of HF self-care that showed adequate fit to the data. Third, we showed in a sample of 1.192 HF patients that only about the 20% of them performs adequate self-care. Forth, we described caregiver contribution to self-care in a sample of 515 HF caregivers and we showed a low level of caregiver contribution to HF self-care. Fifth, we showed that patients and caregivers influence each other self-care. Six, we found that self-care confidence mediates between cognition and self-care, and comorbidity moderates between self-care confidence and self-care. Intervention studies are needed to improve self-care in Italian HF patients
[Newspaper Clipping: Author Claims Evidence of Second JFK Assassin #1]

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
The Caregiver Preparedness Scale is valid and reliable to measure preparedness in caregivers of heart failure patients
No full textLogarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
