The outcomes of total knee arthroplasty following the incidental finding of tuberculosis and its treatment: A prospective study.

Introduction: Extrapulmonary tuberculosis (EPTB) accounts for 16 % of tuberculosis cases globally, with knee joint tuberculosis more prevalent in underdeveloped nations. Total knee arthroplasty (TKA) is commonly used to treat tubercular arthritis of knee, however, there is a marked paucity of research on the outcomes after an incidental diagnosis. The aim of the study is to investigate the outcomes of total knee arthroplasty after an incidental diagnosis of tuberculosis and its management.

[Impact of the disease: acceptability, ceiling and floor effects and reliability of an instrument on heart failure].

This study evaluated the acceptability, ceiling/floor effects, and the reliability of the instrument for measuring the Impact of the Disease on the Daily Life of Patients with Valvular Disease (IDCV) when applied to 135 patients with heart failure (HF). Acceptability was evaluated by the percentage of unanswered items and by the proportion of patients who responded to all items; the ceiling/floor effects by the percentage of patients who scored in the top of 10% best and worst results of the scale, respectively. Reliability was estimated by internal consistency (Cronbach's alpha coefficient) and stability of the measure (intraclass correlation coefficient - ICC).

Reliability and practical aspects of the disease impact measure on hypertensive patients.

Objective: to evaluate the feasibility, acceptability, the ceiling and floor effects and the reliability of the Instrument to Measure the Impact of Coronary Disease on Patient's Daily Life (IDCV) when applied to hypertensive patients.

Method: one hundred and thirty seven hypertensive outpatients were interviewed, using questionnaires to collect sociodemographic and clinical data, followed by the IDCV. Reliability was assessed according to the temporal stability and internal consistency criteria.
