Background: As Japan's aging society needs more blood, young students comprise a progressively smaller portion of the donor pool. To ensure a safe and sustainable blood supply, it is crucial to select suitable donors. This study aims to evaluate donor deferral rates, causes of deferral, and characteristics of deferred Japanese students.
Methods: Computerized records of blood centers in northern Japan (Miyagi and Fukushima Prefectures) from March 2010 through March 2011 were retrospectively analyzed.
Results: Among 231,361 individuals visiting during the 12-month period, 24,778 were students. Of these, 19,193 (77%) attempted donation, and 5,585 (23%) were deferred. Low hemoglobin, questionnaire-based interview decisions, and medication were the main reasons for temporary deferral. Age, sex, and blood center location were associated with low hemoglobin; donation history and blood center location were associated with medication-based deferral. The odds ratio among female students deferred for low hemoglobin was 35.48 with a 95% CI of 27.74-45.38.
Conclusions: These results suggest that continued efforts are needed to motivate deferred potential donors to return, to prevent low hemoglobin especially among females, and to review medical interview decisions, while paying close attention to regional differences.

Buprenorphine has superior safety in opioid use disorder compared with alternatives due to its action as a partial opioid agonist, which limits its ability to cause respiratory depression. There is a risk of precipitated opioid withdrawal after buprenorphine exposure in someone using full opioid agonists. Buprenorphine induction strategies that avoid precipitated withdrawal remain a crucial component for starting buprenorphine in individuals actively using opioids.

Importance: Medication adherence is important for managing blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), and hemoglobin A1c (HbA1c). Interventions to improve medication adherence are needed.
Objective: To examine the effectiveness of an intervention using algorithmic identification of low medication adherence, clinical decision support to physicians, and pharmacist outreach to patients to improve cardiometabolic medication adherence and BP, LDL-C, and HbA1c control.

Introduction: Specimens suspected of errors related to low hemoglobin or changes in hemoglobin beyond that of clinically explained variations during hospital stays are frequently redrawn under the auspices that they are contaminated. When lack of an indwelling IV eliminates contamination as a possibility, evaluation of the specimen between the time of collection and testing should occur.
Methods: As part of a quality improvement project, we investigated the impact of sedimentation on collected blood specimens not immediately transferred to their respective tubes from a syringe.

Background: The aim of this study is to investigate the clinical significance of cerebrospinal fluid (CSF) α-synuclein (αSyn), a presynaptic protein, in Alzheimer's disease (AD) continuum.
Method: We analyzed 177 CSF samples obtained from participants of Japanese Alzheimer's Disease Neuroimaging Initiative (J-ADNI). To investigate the clinical utility of CSF αSyn, subjects were divided into cognitively unimpaired (CU) group (n = 46), mild cognitive impairment (MCI) group (n = 76), and AD dementia (ADD) group (n = 43).
Background: Mild cognitive impairment (MCI) is largely under-diagnosed by primary care physicians. There is an urgent need to develop new objective screening tools to assist with early detection of MCI. Time-domain functional near-infrared spectroscopy (TD-fNIRS) can be used to measure brain function in clinical settings and may fill this need.
