Factors influencing the diagnostic accuracy of the rapid influenza antigen detection test (RIADT): a cross-sectional study.

Objective: To evaluate the diagnostic accuracy of the rapid influenza antigen detection test (RIADT) and determine which symptoms are relevant to results.

Design: Single-centre, cross-sectional study.

Setting: Primary care centre, Tokyo, Japan.

Near point-of-care administration by the attending physician of the rapid influenza antigen detection immunochromatography test and the fully automated respiratory virus nucleic acid test: contribution to patient management.

Rapid influenza antigen detection tests (RIADTs) using immunochromatography are the most readily available tools for the diagnosis and management of influenza. This study was designed to assess whether near point-of-care administration by primary care physicians of the RIADT and a fully automated respiratory virus nucleic acid test (Verigene Respiratory Virus Plus®; RV+) would contribute to improved patient management. When viral culture and RT-PCR/bi-directional sequencing were used as the gold standard, sensitivities and specificities for RIADT and RV+ were 58.

[Clinical analysis of mortality in elderly patients with community-acquired pneumonia].

Aim: Community-acquired pneumonia remains a common and serious disease for elderly persons. The incidence and mortality rates of pneumonia are higher in the elderly. We analyzed the mortality and prognostic factors in 200 elderly patients with community-acquired pneumonia.

[Causes of death in hospitalized elderly patients].

Aim: The Juntendo Tokyo Koto Geriatric Medical Center (JTKGMC) is a community hospital catering for the health care needs of senior citizens, and 37.5% (120 beds) of its beds are psychiatric beds mostly for those with cognitive impairment. The purpose of this study was to analyze cause of death in a hospital like ours with its particular case mix.
