Limitations of Online Information on Abdominal Aortic Aneurysm
Carolyn G. Goldberg,Loren Berman,Richard J. Gusberg
International Journal of Vascular Medicine , 2010, DOI: 10.1155/2010/789198
Abstract: Background. Patients with AAA face a complex decision, and knowledge of the risks and benefits of each treatment option is essential to informed decision-making. Here we assess the current information on the internet accessible to patients regarding the management of AAA. Study Design. We performed a search on Google using the keywords “abdominal aortic aneurysm” and reviewed the top 50 web sites. We focused on information related to treatment options and alternatives to treatment and the risks of each option. Results. Twenty-seven websites were included in the study. Nearly 30% of websites discussed the risk of mortality and myocardial infarction after open surgery, compared to only 7.4% for both risks after EVAR. Other complications were listed by fewer websites. Fifty-five percent of websites reported that patients had a faster recovery following EVAR, but only 18.5% mentioned the risk of reintervention after EVAR or the need for long-term surveillance with CT scans. Conclusions. While most websites included descriptive information on AAA and mentioned the potential treatment options available to patients, the discussion of the risks of open surgery and EVAR was inadequate. These results suggest that websites frequently accessed by patients lack important information regarding surgical risk. 1. Introduction When diagnosed with an abdominal aortic aneurysm (AAA), patients are confronted with a complex decision: whether or not to undergo invasive treatment for an asymptomatic but potentially fatal condition. If patients elect to pursue surgical treatment, many must further decide between open surgery and endovascular repair (EVAR). Knowledge of the natural history of AAA as well as the risks and benefits of all treatment options is essential for patients to make a well-informed decision. Effective communication of this information during the informed consent process can be challenging because of the volume and complexity of the information involved as well as the emotional impact of the potentially life-changing alternatives being considered. We have previously reported that many patients neither appreciated the scope of their options before AAA repair nor felt adequately informed prior to making a decision [1]. Given the complexity and variability of information, it is not surprising that many patients do not feel well informed about possible outcomes of surgical intervention. It has been well documented that education increases patient satisfaction with decision making [2–5]. The internet has the potential to provide patients with information and
Heat Flow as Origin of Dark Energy  [PDF]
Marcelo Samuel Berman
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.410175

We first introduce entropy according to University Physics textbooks, then, briefly discuss it, and then we prove by a general relativistic derivation that the Universe has entropy growth, like a white-hole, that it is R2-dependent, and that dark energy, represented by a cosmological constant, is caused by heat flow, and provides for entropy growth.

Auto-percep??o de aluna de enfermagem ao desenvolver rela??o de ajuda a familiares de crian?a em fase terminal
Loren?on, Marisa;
Revista Latino-Americana de Enfermagem , 1998, DOI: 10.1590/S0104-11691998000400008
Abstract: the present study aims at reporting and analysing the therapeutic approach of children under intensive care and studying the relationship between nurse and mother. facing the illness of a dying child and within a sometimes hostile and emotional environment, the student is trained to help the family and their problems. the student's own anxiety and difficulties in managing these situations are evaluated.

Abstract: While the Panic of 1907 began in New York City, its effects reverberated throughout the United States. This article examines the response of Oklahoma banks to the nationwide restriction of payments beginning in late October of that year. Despite the widespread support of local communities for their banks, Oklahoma institutions cut back on loans and built up their reserves to a greater degree than did country banks nationwide. Of particular concern for Oklahomans in late 1907 was the financing of the cotton crop. Balance sheet evidence suggests that Oklahoma banks in cotton-growing areas reacted more defensively than did banks in wheat-growing areas, where the harvest had already been completed. A multiple regression model exploring changes in Oklahoma bank reserves before and after the Panic not only confirms the relevance of cotton as a factor but also points to bank size, the use of cash substitutes, and political jurisdiction as variables that influenced the extent to which Oklahoma banks increased their reserves in response to the Panic.

Essays in Economic & Business History , 2008,
Abstract: The Great Depression in the United States produced a great outpouring of local currencies as responses to various aspects of the economic crisis. This article describes the basic types of scrip in use, assesses their legality and theoretical justification, and ventures some generalizations as to what sorts of scrip worked best. It argues that the widespread use of local scrip was not motivated by any systematic analysis of the shortcomings of the national economy, or of its monetary system. Rather, the scrip movement represented eclectic responses to specific economic problems created by the Depression.
Self-fashioning, Freedom, and the Problem of His-story: the return of noir
Scott Loren
European Journal of American Studies , 2008, DOI: 10.4000/ejas.1842
Abstract: With a mix of two patently American film genres - film noir and the western - David Cronenberg’s critically acclaimed A History of Violence (2005) sets up a group of oppositions through the story of a man who leaves a life of crime and violence behind to assume a new identity, start a family, and settle down in the quiet town of Millbrook, Indiana. The oppositions between gangster thug, super-killer and good citizen, family-man are paralleled in another opposition particularly typical to the ...
Examples of DLR states which are not weak limits of finite volume Gibbs measures with deterministic boundary conditions
Loren Coquille
Mathematics , 2014, DOI: 10.1007/s10955-015-1211-3
Abstract: We review what is known about the structure of the set of weak limiting states of the Ising and Potts models at low enough temperature, and in particular we prove that the mixture $\frac12(\mu^\pm+\mu^\mp)$ of two reflection-symmetric Dobrushin states of the 3-dimensional Ising model at low enough temperature is a Gibbs state which is not a limit of finite-volume measures with deterministic boundary conditions. Finally we point out what the issues are in order to extend the analysis to the Potts model, and give a few conjectures.
Topological Jordan decompositions
Loren Spice
Mathematics , 2006,
Abstract: The notion of a topological Jordan decomposition of a compact element of a reductive p-adic group has proven useful in many contexts. In this paper, we generalise it to groups defined over fairly general discretely-valued fields and prove the usual existence and uniqueness properties, as well as an analogue of a fixed-point result of Prasad and Yu.
On counting orbits in root systems
Loren Spice
Mathematics , 2013,
Abstract: The computation of the characters of supercuspidal representations of a p-adic group involves some 4th roots of unity whose values are defined in terms of orbits of the Galois group of a p-field on a root system. The part of the definition that is of interest in the verification of stability of character sums involves just the parity of the number of Galois orbits. In this paper, we re-cast the definition (nearly) in terms only of the abstract action of a pair of automorphisms on a root system, and compute it by a series of reductions in all cases.
Fourier transforms of orbital integrals on the Lie algebra of $\operatorname{SL}_2$
Loren Spice
Mathematics , 2010,
Abstract: The Harish-Chandra--Howe local character expansion expresses the characters of reductive, $p$-adic groups in terms of Fourier transforms of nilpotent orbital integrals on their Lie algebras, and Murnaghan--Kirillov theory expresses many characters of reductive, $p$-adic groups in terms of Fourier transforms of semisimple orbital integrals (also on their Lie algebras). In many cases, the evaluation of these Fourier transforms seems intractable; but, for $\operatorname{SL}_2$, the nilpotent orbital integrals have already been computed. In this paper, we use a variant of Huntsinger's integral formula, and the theory of $p$-adic special functions, to compute semisimple orbital integrals.
