Mild Parkinsonian signs are associated with lower olfactory test scores in the community-dwelling elderly

Mild Parkinsonian signs (MPS, impaired gait, rigidity, bradykinesia, rest tremor) are commonly found during the clinical examination of older people and may be a precursor to Parkinson's disease (PD) or Alzheimer's disease (AD). Marked deficits in olfaction occur in PD and AD. The objective of this study was to determine whether University of Pennsylvania Smell Test (UPSIT) scores were lower in nondemented community-dwelling elderly with versus without MPS. Nondemented persons age ≥65 years without PD in Washington Heights-Inwood, NY were evaluated with an abbreviated motor Unified PD Rating Scale and a 40-item UPSIT. Lower UPSIT and higher transformed UPSIT score (square root [UPSIT - 41]) indicated greater olfactory dysfunction. One-hundred-seventy-seven (16.4%) of 1,078 participants had MPS. Mean UPSIT scores (MPS vs. without MPS) were 24.3 ± 7.1 versus 26.4 ± 6.8, P < 0.001. In a logistic regression analysis adjusting for age and education, transformed UPSIT score was associated with MPS (OR 1.25, 95% CI 1.04–1.52, P = 0.02). In an adjusted logistic regression analysis, participants with higher transformed UPSIT scores (based on a median split) were 1.55 times more likely to have MPS than were those with lower scores (P = 0.01). Within transformed UPSIT score quartiles, the odds of having MPS were 1.0 (reference), 1.35, 2.02, and 2.20 (P < 0.05). The association with transformed UPSIT scores was similar across MPS subtypes (axial dysfunction, rigidity, tremor).MPS were associated with a mild reduction in olfactory function. These observations further support the view of MPS as a marker of emerging degenerative brain pathologies. © 2007 Movement Disorder Society

Patient recruitment to a randomized clinical trial of behavioral therapy for chronic heart failure

BACKGROUND: Patient recruitment is one of the most difficult aspects of clinical trials, especially for research involving elderly subjects. In this paper, we describe our experience with patient recruitment for the behavioral intervention randomized trial, "The relaxation response intervention for chronic heart failure (RRCHF)." Particularly, we identify factors that, according to patient reports, motivated study participation. METHODS: The RRCHF was a three-armed, randomized controlled trial designed to evaluate the efficacy and cost of a 15-week relaxation response intervention on veterans with chronic heart failure. Patients from the Veterans Affairs (VA) Boston Healthcare System in the United States were recruited in the clinic and by telephone. Patients' reasons for rejecting the study participation were recorded during the screening. A qualitative sub-study in the trial consisted of telephone interviews of participating patients about their experiences in the study. The qualitative study included the first 57 patients who completed the intervention and/or the first follow-up outcome measures. Factors that distinguished patients who consented from those who refused study participation were identified using a t-test or a chi-square test. The reason for study participation was abstracted from the qualitative interview. RESULTS: We successfully consented 134 patients, slightly more than our target number, in 27 months. Ninety-five of the consented patients enrolled in the study. The enrollment rate among the patients approached was 18% through clinic and 6% through telephone recruitment. The most commonly cited reason for declining study participation given by patients recruited in the clinic was 'Lives Too Far Away'; for patients recruited by telephone it was 'Not Interested in the Study'. One factor that significantly distinguished patients who consented from patients who declined was the distance between their residence and the study site (t-test: p < .001). The most frequently reported reason for study participation was some benefit to the patient him/herself. Other reasons included helping others, being grateful to the VA, positive comments by trusted professionals, certain characteristics of the recruiter, and monetary compensation. CONCLUSIONS: The enrollment rate was low primarily because of travel considerations, but we were able to identify and highlight valuable information for planning recruitment for future similar studies

Cancer diagnosis as discursive capture: Phenomenological repercussions of being positioned within dominant constructions of cancer

This paper is concerned with the phenomenological repercussions of being positioned within widely available discursive constructions of cancer. One of the many challenges of being diagnosed with cancer is that it requires the person to make sense of the diagnosis and to find meaning in their changed circumstances. From a social constructionist point of view, such meaning is made out of discursive resources which are available within one’s culture. This paper critically reviews some of the dominant discourses surrounding cancer which are available within English-speaking Western industrialized cultures. It maps out the discursive positions available to those diagnosed with cancer and it traces some of their implications for how cancer may be experienced and how it may be lived with. As such, this paper is concerned with the social and psychological consequences of being positioned within dominant cancer discourses

Textual Deixis and the ‘Anchoring’ Use of the Latin Pronoun hic

This article evaluates the results of prior research on anaphoric reference in Latin, and tries to account for the various observations within a single explanatory framework. This framework combines insights from cognitive linguistic theory and from ongoing empirical research on the linguistic marking of discourse organization in Latin. After a brief discussion of recent cognitive linguistic views on the relation between deixis and anaphora, I concentrate on the various uses of the Latin demonstrative hic in Virgil’s Aeneid and Ovid’s Metamorphoses. The examples discussed show that hic’s deictic aspect of proximity can be discerned in all its uses, the variety of which can best be described in terms of a ‘cline’, running from canonical deixis to canonical anaphora, with various stages of anadeixis in between. It is argued that in its anaphoric use, Latin hic behaves as a linguistic ‘anchoring’ device, and is used as part of a communicative strategy referred to as ‘reculer pour mieux sauter’

The Role of Individual Variables, Organizational Variables and Moral Intensity Dimensions in Libyan Management Accountants’ Ethical Decision Making

This study investigates the association of a broad set of variables with the ethical decision making of management accountants in Libya. Adopting a cross-sectional methodology, a questionnaire including four different ethical scenarios was used to gather data from 229 participants. For each scenario, ethical decision making was examined in terms of the recognition, judgment and intention stages of Rest’s model. A significant relationship was found between ethical recognition and ethical judgment and also between ethical judgment and ethical intention, but ethical recognition did not significantly predict ethical intention—thus providing support for Rest’s model. Organizational variables, age and educational level yielded few significant results. The lack of significance for codes of ethics might reflect their relative lack of development in Libya, in which case Libyan companies should pay attention to their content and how they are supported, especially in the light of the under-development of the accounting profession in Libya. Few significant results were also found for gender, but where they were found, males showed more ethical characteristics than females. This unusual result reinforces the dangers of gender stereotyping in business. Personal moral philosophy and moral intensity dimensions were generally found to be significant predictors of the three stages of ethical decision making studied. One implication of this is to give more attention to ethics in accounting education, making the connections between accounting practice and (in Libya) Islam. Overall, this study not only adds to the available empirical evidence on factors affecting ethical decision making, notably examining three stages of Rest’s model, but also offers rare insights into the ethical views of practising management accountants and provides a benchmark for future studies of ethical decision making in Muslim majority countries and other parts of the developing world

Current and Future Drug Targets in Weight Management

Obesity will continue to be one of the leading causes of chronic disease unless the ongoing rise in the prevalence of this condition is reversed. Accumulating morbidity figures and a shortage of effective drugs have generated substantial research activity with several molecular targets being investigated. However, pharmacological modulation of body weight is extremely complex, since it is essentially a battle against one of the strongest human instincts and highly efficient mechanisms of energy uptake and storage. This review provides an overview of the different molecular strategies intended to lower body weight or adipose tissue mass. Weight-loss drugs in development include molecules intended to reduce the absorption of lipids from the GI tract, various ways to limit food intake, and compounds that increase energy expenditure or reduce adipose tissue size. A number of new preparations, including combinations of the existing drugs topiramate plus phentermine, bupropion plus naltrexone, and the selective 5-HT2C agonist lorcaserin have recently been filed for approval. Behind these leading candidates are several other potentially promising compounds and combinations currently undergoing phase II and III testing. Some interesting targets further on the horizon are also discussed
