Recent daily life burdens associated with neovascular age-related macular degeneration involve difficulties in use of electronic devices.

Neovascular age-related macular degeneration (nAMD) is a prevalent cause of permanent vision loss and blindness in the elderly worldwide, with a significant impact on patients' daily lives. However, burdens related to nAMD from the patients' perspective have not been well documented. Here we developed a new questionnaire after eliciting nAMD patients' daily challenges followed by a pilot survey.

The treatment patterns of castration-resistant prostate cancer in Japan, including symptomatic skeletal events and associated treatment and healthcare resource use.

Background: Real-world treatment patterns of bone metastatic castration-resistant prostate cancer (mCRPC) in Japan were examined, focusing on treatment patterns and resource use differences attributed to symptomatic skeletal events (SSEs).

Methods: Urologists (N = 176) provided retrospective chart data for patients with mCRPC (N = 445) via online surveys. Descriptive analyses and chi-square tests evaluated treatment patterns and their differences by SSE presence; generalized linear mixed models examined healthcare resource utilization differences as a function of SSEs.

Patient preferences for treatment of castration-resistant prostate cancer in Japan: a discrete-choice experiment.

Background: Up to a fifth of patients diagnosed with prostate cancer (PC) will develop castration-resistant prostate cancer (CRPC), which has been associated with a poor prognosis. The aim of this study was to consider the patient perspective as part of the overall treatment decision-making process for CRPC, given that an alignment between patient preference and prescribing has been shown to benefit patient outcomes. This study examines preferences of patients with CRPC in Japan for treatment features associated with treatments like RA-223, abiraterone, and docetaxel and to examine the extent to which treatment preferences may vary between symptomatic and asymptomatic patients.

Ethnic comparison of pharmacokinetics of (18)F-florbetaben, a PET tracer for beta-amyloid imaging, in healthy Caucasian and Japanese subjects.

Purpose: (18)F-Florbetaben is a positron emission tomography (PET) tracer indicated for imaging cerebral beta-amyloid deposition in adult patients with cognitive impairment who are being evaluated for Alzheimer's disease and other causes of cognitive decline. The present study examined ethnic comparability of the plasma pharmacokinetics, which is the input to the brain, between Caucasian and Japanese subjects.

Methods: Two identical phase I trials were performed in 18 German and 18 Japanese healthy volunteers to evaluate the plasma pharmacokinetics of a single dose of 300 MBq (18)F-florbetaben, either of low (≤5 μg, LD) or high (50-55 μg, HD) mass dose.

A multicenter, randomized, controlled, single-blind comparison phase III study to determine the efficacy and safety of gadobutrol 1.0 M versus gadopentetate dimeglumine following single injection in patients referred for contrast-enhanced MRI of the body regions or extremities.

Purpose: To demonstrate the noninferiority of gadobutrol-enhanced magnetic resonance imaging (MRI) compared with gadopentetate dimeglumine-enhanced MRI in Asian patients referred for contrast-enhanced imaging of the body or extremities.

Materials And Methods: A multicenter, parallel-group comparison study of Asian adults referred for contrast-enhanced MRI were randomized (1:1) to either gadobutrol or gadopentetate dimeglumine. Lesions were assessed for three primary visualization variables: degree of contrast enhancement, border delineation, and internal morphology.

Magnetic resonance evaluation of brain metastases from systemic malignances with two doses of gadobutrol 1.0 m compared with gadoteridol: a multicenter, phase ii/iii study in patients with known or suspected brain metastases.

Objectives: To determine the efficacy and safety of 2 doses of gadobutrol 1.0 M (0.1 and 0.
