Multicenter Study
Outcome of one-year of specialist care of patients with type 2 diabetes: a multi-center prospective survey (JDDM 2).
Specialist care is reportedly associated with favorable therapeutic results, although detailed outcomes of recent large-scale prospective surveys of specialist care have yet to be published. The goal of this study was to elucidate the effects of one year's specialist care on the management of type 2 diabetes. ⋯ Diabetic patients under specialist care experienced substantial improvement, especially in glycemic control, as early as a few months after the first visit. However, 35 percent of patients dropped out during the 12-month study period and this is one area that needs to be improved.

Multicenter Study Clinical Trial
The effect of combined therapy according to the guidelines for the treatment of Mycobacterium avium complex pulmonary disease.
To investigate whether the combined therapy according to the guideline proposed by American Thoracic Society (ATS) and Japanese Society for Tuberculosis (JST) is clinically appropriate for Mycobacterium avium complex (MAC) pulmonary disease. ⋯ This combined therapy, according to the guideline proposed by ATS and JST, was one of the effective treatments compared to the clinical effect of only antituberculous drugs through this study. However, this combined therapy was unsatisfactory compared to the clinical effect for pulmonary tuberculosis. The development of new companion drugs for MAC pulmonary diseases is needed.

Multicenter Study Comparative Study
Prediction of life expectancy in patients with primary pulmonary hypertension. A retrospective nationwide survey from 1980-1990.
Primary pulmonary hypertension (PPH) is a progressive disease of unknown etiology usually followed by death within 5 years after diagnosis. Although heart-lung or lung transplantation is now offered to patients with advanced PPH, adequate criteria assessing an accurate prediction of life expectancy in PPH has been difficult to establish. The aims of this study were to identify the characteristic features associated with a poor prognosis in patients with PPH, and to attempt to establish an individual prognostic index that predicts with great accuracy survival or death of PPH after one year, thereby helping to define criteria for patient selection for transplantation. ⋯ As the independent factors, PPA, PRA, SI, and PaCO2 were selected for the multiple logistic analysis. Using a 0.7 probability cut-point to separate Nonsurvivors from Survivors, 84.6% of Nonsurvivors and Survivors could be correctly predicted from this logistic regression equation. Predictive equations like the present preliminary one can be used in the future to better assess life expectancy in patients with PPH in whom transplantation will be considered.
