Current user interfaces for automated patient and consumer health care systems can be improved by leveraging the results of several decades of research into effective patient-provider communication skills. A research project is presented in which several such "relational" skills - including empathy, social dialogue, nonverbal immediacy behaviors, and other(More)
Relational agents are computational artifacts, such as animated, screen-based characters or social robots, that are designed to establish a sense of rapport, trust, and even therapeutic alliance with patients, using ideal therapeutic relationships between human counselors and patients as role models. We describe the development and evaluation of several(More)
Obstructive sleep apnoea (OSA) is a cardio-metabolic disorder. Whether metabolic syndrome (MS), insulin resistance (IR) and albuminuria are independently associated with OSA is unclear, but defining the interactions between OSA and various cardiovascular (CV) risk factors independent of obesity facilitates the development of therapeutic strategies to(More)
OBJECTIVE To determine whether low serum B12 levels are associated with an increased incidence of dementing illness. DESIGN Longitudinal cohort study, 5-year follow-up. PARTICIPANTS Volunteer cohort of 410 nondemented ambulatory subjects aged 75 to 85 years. MEASUREMENTS Annual serum B12 determinations and neuropsychological assessments including the(More)
Obesity is growing into a global epidemic and alarming trends are seen in Asian countries. Although obesity is defined by body mass index (BMI), waist circumference has emerged as a more specific marker of metabolic risk. BMI and waist circumference thresholds vary between ethnicities and values are lower for Asian populations. Asians are at an increased(More)
BACKGROUND/AIMS Among the causes related to the development or perpetuation and aggravation of dry eye disease, oxidative reactions may have a role in the pathogenesis of this disorder. Antioxidants, such as iodide, have shown a strong effect in preventing the oxidative damage to constituents of the anterior part of the eye. In this clinical trial the(More)
The objective of this article is to review clinical outcomes in patients presenting with pituitary apoplexy and compare the results of conservative and surgical management. It took the form of a retrospective review of 30 patients (23M, 7F; age range: 17-86 years) with pituitary apoplexy diagnosed between 1988 and 2004. Presenting features included headache(More)
There is an increased incidence of tumors of the genitourinary tract among kidney graft recipients. From 1979 to 2001, all patients who received kidney transplants had records of both their underlying diseases and their initial immunosuppression. Patients who developed a genitourinary tract malignancy were evaluated for tumor type, location, stage, tumor(More)
Esophageal acid exposure is believed to be a major source of unexplained chest pain; but, individual episodes of reflux in pH study are not consistently associated with chest pain. Our aim was to discover whether prior sensitization of esophageal mucosa by acid reflux predisposes to reflux-induced chest pain. Ambulatory pH studies of patients referred to(More)
Over the past years, there has been an explosive increase in the prevalence of type 2 diabetes (T2DM) and this is expected to continue, entailing associated morbidity and mortality. An increasing number of studies explore the different ways T2DM could be prevented. On-going lifestyle modifications need to be addressed. High-risk patients should be given(More)
