1) A beta agonist stimulated Na+ transport and decreased the intracellular Cl concentration ([Cl]c) associated with cell shrinkage via an increase in cytosolic cAMP level by activating adenylate cyclase in rat fetal distal lung epithelial (FDLE) cells. 2) Lowering [Cl-]c activated a 28-pS nonselective cation (NSC) channel by elongating the open time of the channel. 3) cAMP signals were converted to a protein tyrosine kinase (PTK)-mediated signal. 4) The PTK-mediated signal was involved in the cAMP-stimulated Na+ transport in rat FDLE cells.

The purpose of this study was to analyze the body characteristics of university soccer players, especially the hip joint and pelvis where chronic injuries frequently occur among soccer players.
Body characteristics of seventy male university soccer players were surveyed by an orthopedic medical check. The Micro FET value (MF) was used as the unique test for the potential stress on the pubic symphysis. MF was defined as the pressure value at which a subject claimed tenderness from compression on the pubic symphysis.
Among the various tests of the orthopedic medical check, trunk extension in the prone position and external rotation of the hip joint in the standing position correlated with MF. The same tendencies were observed in soccer players with pubic symphysitis.
Results indicate that these three simple tests : MF, trunk extension in the prone position and external rotation of the hip joint in the standing position, can be used as valuable indices for detecting pubic symphysitis in the early stages.

PURPOSE: The aim of this study was to evaluate the validity and reliability of the Seattle Angina Questionnaire, Japanese version (SAQ-J) as a disease-specific health outcome scale in patients with coronary artery disease. METHODS: Patients with coronary artery disease were recruited from a university hospital in Tokyo. The patients completed self-administered questionnaires, and medical information was obtained from the subjects' medical records. Face validity, concurrent validity evaluated using Short Form 36 (SF-36), known group differences, internal consistency, and test-retest reliability were statistically analyzed. RESULTS: A total of 354 patients gave informed consent, and 331 of them responded (93.5%). The concurrent validity was mostly supported by the pattern of association between SAQ-J and SF-36. The patients without chest symptoms showed significantly higher SAQ-J scores than did the patients with chest symptoms in 4 domains. Cronbach's alpha ranged from .51 to .96, meaning that internal consistency was confirmed to a certain extent. The intraclass correlation coefficient of most domains was higher than the recommended value of 0.70. The weighted kappa ranged from .24 to .57, and it was greater than .4 for 14 of the 19 items. CONCLUSIONS: The SAQ-J could be a valid and reliable disease-specific scale in some part for measuring health outcomes in patients with coronary artery disease, and requires cautious use.

Medical Education 2023;54(4):357-366
This paper describes the concepts of assessment theory which are necessary to implement the most desirable assessments, with a particular focus on validity and utility. Validity, classically defined as a trinity of content, criterion-related, and construct, is now encompassed by construct validity. By distinguishing between validity and validation, the process of reinforcing validity through argument-based validation is proposed. Furthermore, we refer to the concept of utility, which takes into account practicality (acceptability and cost) and educational impact, in order to make the assessment practice sustainable. Finally, we will address how learner assessment relates to program evaluation.

Objective:
The long-term efficacy of deep brain stimulation (DBS) for motor fluctuations in advanced Parkinson’s disease (PD) has been well established; however, motor fluctuations may recur over time despite multiple adjustments of DBS settings and medications.
Methods:
We conducted a retrospective chart review of three patients for whom levodopa-carbidopa intestinal gel (LCIG) was additionally administered as a rescue therapy for secondary DBS failure due to the recurrence of motor fluctuations.
Results:
The three patients had advanced PD with a disease duration of 14–19 years, and had undergone DBS for motor fluctuations refractory to standard medical management. LCIG was administered to the patients because of symptom recurrence years after DBS and provided complementary effects in all patients.
Conclusion
The cases presented here show that rescue LCIG therapy may be a complementary treatment option for patients with post-DBS advanced PD who have a recurrence of troublesome motor complications.

Since late 2013 through March 2014, Japan experienced a rapid rise in measles cases. Here, we briefly report on the ongoing situation and share preliminarily findings, concerns and challenges and the public health actions needed over the coming months and years.
Measles is a notifiable disease in Japan based on nationwide case-based surveillance legally requiring physicians to report all clinically diagnosed and laboratory-confirmed cases within seven days, but preferably within 24 hours. After a large outbreak in 2007–2008 (more than 11 000 cases reported in 2008 alone) and a goal of elimination by April 2015, a catch-up programme using the bivalent measles-rubella (MR) vaccine was offered for grades seven and 12 (ages 12–13 and 17–18 years) from April 2008 through March 2013. During this period, there was an estimated 97% decline in measles notifications, and the cumulative number of reported cases has been steadily declining over the last five years (732 cases in 2009, 447 cases in 2010, 439 cases in 2011, 293 cases in 2012 and 232 cases in 2013). However, since late 2013 through March 2014, the country experienced a resurgence only a year after a large rubella outbreak.

In the 2022 Model Core Curriculum for Medical Education in Japan, "Chapter 3, Educational strategies and assessment" section II. "Learner Assessment," consists of three parts : II-1. Approaches to learner assessment, II-2. Assessment methods, and II-3. Questions about learner assessment. Based on the idea that "the way assessment is done varies from institution to institution," the answer to the "Question" is deliberately not included. We hope that readers will refer to this chapter when planning learning assessments in curriculum development while considering the curriculum's background and context.
