Abstract

Because they accurately and efficiently tap into important aspects of rheumatic disease status and outcome, health status questionnaires have found increasing use in the clinic, controlled clinical trials, and observational studies. This article reviews utility assessment methodologies as well as generic and disease-specific health status questionnaires relevant to rheumatology.

Assessing local influence in principal component analysis with application to haematology study data.

In many medical and health studies, high-dimensional data are often encountered. Principal component analysis (PCA) is a commonly used technique to reduce such data to a few components that includes most of the information provided by the original data. However, PCA is known to be very sensitive to some abnormal observations. Therefore, it is essential to assess such sensitivity in PCA. In this paper, the assessments of local influence based on generalized influence function are developed under the case-weights and additive perturbation schemes, along with a discussion of the perturbation scheme and the generalized influence function approach. When perturbing different variables of the data, it is noted that the directions of the largest joint local influence for the eigenvalues are all the same. Moreover, these directions are completely determined by the score values of the observations, to which an approximate cut-off point is given. The proposed methods are applied to analyse a set of haematology study data for illustration. Results add new insights in finding influential observations in the studied data set.

Quality of life in nonallergic rhinitis.

Health-related quality-of-life questionnaires are instruments to assess the burden of a disease as perceived by the patient. Few data are available on the health-related quality of life of patients with nonallergic rhinitis, but data from studies of patients with allergic rhinitis show that rhinitis predominantly affects mental quality of life. This burden of rhinitis is associated with impaired sleep, excessive daytime sleepiness, concentration problems, and increased irritability.
