BACKGROUND This study was designed to develop and validate a patient-reported outcomes measure, sensitive to the different features of diabetic neuropathy (DN)-small fiber, large fiber, and autonomic nerve function. METHODS The review of 1,000 structured patient interviews guided the development of 28 items pertaining specifically to the symptoms and(More)
OBJECTIVE To develop a disease-specific questionnaire for identifying domains having the greatest impact on the quality of life (QOL) of patients with neuroendocrine tumors (NETS). METHODS Patient responses to clinical interviews provided an 80-item initial pool for the development of the QOL-NET. The Delphi panel reviewed the items for content validity;(More)
BACKGROUND The Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QOL-DN) is a validated comprehensive questionnaire designed to capture the entire spectrum of DN related to large fiber, small fiber, and autonomic neuropathy not captured in existing instruments. We aimed to determine if the Norfolk QOL-DN could be used to capture changes in(More)
The measurement of health-related quality of life (HRQOL) has become essential for evaluating the impact of neuroendocrine tumors (NETs) on symptoms and social, emotional, psychological, and physical functioning of patients who harbor these tumors. This article describes instruments that have been developed to capture the spectrum of symptoms and the impact(More)
BACKGROUND The development and validation of Norfolk QOL-DN, a fiber-specific, quality-of-life tool for diabetic neuropathy, was published previously (Part 1). This study (Part 2) defines the psychometric properties of the German-translated Norfolk QOL-DN in a large multicenter (96 sites) population with neuropathy ranging from minimal to severe, comparing(More)
For patients with diabetes mellitus (DM), chronic complications can be devastating. Cardiovascular illness, the major cause of morbidity and mortality among these patients, encompasses macrovascular disease, with heart attacks, strokes, and gangrene; and microvascular disease, with retinopathy, nephropathy, and neuropathy (somatic and autonomic).(More)
OBJECTIVES Octreotide long acting repeatable (LAR) is widely used for the control of symptoms of functional neuroendocrine tumors. At doses of 30 mg/mo, up to 40% of patients require subcutaneous octreotide "rescue" and up to 40% of patients are given more than 30 mg of LAR/mo. Octreotide acetate binds to the sst2 receptor with an affinity (Kd) of(More)
OBJECTIVE Chromogranin A (CGA) levels are used to confirm the diagnosis and monitor the course of patients with neuroendocrine tumors. Chromogranin A levels are significantly reduced when patients are acutely treated with octreotide; however, limited data are available that correlates octreotide long-acting repeatable (LAR) dose or steady state octreotide(More)
The Norfolk Quality of Life-Diabetic Neuropathy (QOL-DN) questionnaire is an instrument to assess QOL in diabetic polyneuropathy. The objective of this observational, cross-sectional study in 61 patients with V30M transthyretin familial amyloid polyneuropathy (TTR-FAP) and 16 healthy volunteers was to validate the Norfolk QOL-DN for assessment of QOL in(More)
Falls are a major health issue for older adults, especially for those who develop type 2 diabetes who must contend with age-related declines in balance, muscle strength, and walking ability. They must also contend with health-related issues specific to the disease process. Given the general association between these variables and falls, being able to(More)
