The purpose of the present study was to investigate the relationships of physical fitness, body mass index (BMI), waist-hip ratio (WHR) and sex hormone binding globulin (SHBG) with lipid and glucose metabolism in premenopausal obese women aged 32 to 49 yrs (n=24) . WHR was significantly correlated with HDL-C, HDL2-C and Apo B, but not correlated with BMI %fat, maximal oxygen uptake (VO2max), triglyceride (TG), very low density lipoprotein % fat, and Apo A 1. VO2max/kg was significantly associated with BMI, TG, HDL-C, HDL2-C, Apo Al, low density lipoprotein (LDL), SHBG, glucose metabolism at rest and during oral glucose tolerance test (OGTT) . The SHBG was strongly correlated with HDL-C, HDL2-C and Apo A 1. In multiple regression analysis, it was observed that SHBG was one of the independ-ent predictor of HDL-C, HDL2-C and Apo Al, that VO2max was good predictor of LDL, Apo B and glucose metabolism at rest and during OGTT, and that BMI was one of the determinat of TG and VLDL. From these results, we concluded that lipid metabolism was independently associated with aerobic work capacity, SHBG, BMI as well as WHR, and that glucose metabolism was independently associated with aerobic work capacity.

To confirm the safety and efficacy of a low-calorie mayonnaise supplemented with phytosterol esters (PEM) at a daily consumption dose of 884 mg given for 12 weeks with the goal of lowering serum low-density lipoprotein (LDL) cholesterol levels, we conducted a double-blind comparative study in healthy adults with marginally high serum levels of LDL cholesterol and total cholesterol using a mayonnaise without phytosterol esters supplementation (CM) as the control food. Serum LDL cholesterol levels decreased significantly in the PEM group as compared with the CM group during the 12-week intervention period (136.3 ± 16.4 vs. 145.0 ± 19.3 mg/dL at Week 8 (P < 0.05) and 135.0 ± 17.4 mg/dL vs. 144.9 ± 17.5 mg/dL at Week 12; P < 0.05). No observable adverse effects were observed due to the ingestion of PEM in this study. The safety of PEM was again confirmed by an additional clinical study in which healthy adult subjects ingested a 3-fold greater amount of PEM (2,652 mg of phytosterol esters as a daily dose) for 4 weeks. Thus, we concluded that PEM is effective in lowing serum levels of LDL cholesterol and is safe and well tolerated without any clinical problems.

OBJECTIVES: One of the important risk factors of falling is decreased muscle mass and muscle strength. Recently, there has been an increasing concern on the role of vitamin D in muscle strength and physical activity. Aim of our study is to examine the relationships between vitamin D status and muscle mass and muscle strength in middle-aged healthy adults. METHODS: Subjects were 40 healthy volunteers aged 42.0 ± 10.6 years old. Evaluation was made for serum vitamin D₃ metabolites including 25-hydroxyvitamin D₃ [25(OH)D₃] and 24,25-dihydroxyvitamin D₃ [24,25(OH)₂D₃] concentrations, lower limb muscle strength, and dietary intake by food frequency questionnaire. Body composition was measured by dual-energy X-ray absorptiometry (DXA), and appendicular skeletal mass index (ASMI) was calculated as skeletal muscle mass/squared height. RESULTS: 70% of the subjects had vitamin D insufficiency/deficiency (serum total 25(OH)D < 20 ng/mL), and female subjects had significantly lower serum total 25(OH)D level compared with males. Vitamin D insufficiency/deficiency group had significantly higher body fat, lower SMI and muscle strength, probably reflecting higher percentage of female subjects. Serum vitamin D₃ metabolites levels were significantly correlated with whole and site-specific ASMI, and lower limb muscle strength, except for the correlation between serum 24,25(OH)₂D₃ concentration and lower limb muscle strength. In addition, serum 25(OH)D₃ level was a positive significant predictor for both ASMI and lower limb muscle strength, while serum 24,25(OH)₂D₃ level was not their significant predictor. CONCLUSIONS: Serum 25(OH)D₃ level was significantly correlated with both skeletal muscle mass and lower limb muscle strength.

Following the revision of the structure and content of the Model Core Curriculum for Medical Education to be more outcome-based and the legal status of the medical practice performed by medical students in the clinical clerkship, we have revised the Guideline for Participatory Clinical Clerkship. The following items were revised or newly described : significance of enhancing the participatory clinical clerkship, scope of medical practice, confidentiality, patient consent, patient consultation and support service, objectives of the clinical clerkship, simulation education, departments where the clinical clerkship is conducted, assessment in the clinical practice setting, CC-EPOC, and entrustable professional activities. A foundation has been established to promote seamless undergraduate and postgraduate medical education. However, future work is needed to examine the specific level of performance expected at the end of the clinical clerkship and department-specific clinical practice goals and educational strategies.

BACKGROUND:
Oral health is thought to be associated with diet quality, and socioeconomic status (SES) affects both oral health and diet. The aim of this study was to investigate the association between the number of teeth and dietary intake as well as nutritional biomarker, considering the subjects' SES.
METHODS:
We conducted a cross-sectional analysis of data from 2049 individuals aged ≥ 50 years from the National Integrated Project for Prospective Observation of Non-communicable Disease and its Trends in the Aged 2010. The number of remaining teeth was categorized into age-specific quartiles (Q1 to Q4). We assessed the adjusted means and 95% confidence intervals for dietary variables by the number of teeth using analysis of covariance. Stratified analyses by SES were also conducted.
RESULTS:
The intake of grain products was 31 g higher, and those of vegetables and meat were 30 g and 8 g lower, respectively, in Q1 (fewer teeth) than in Q4 (more teeth). Carbohydrate intake was higher whereas protein, minerals (potassium, magnesium, and zinc), vitamins (vitamins A, E, B, B, β-carotene, and folic acid), and dietary fiber intakes were lower among individuals with fewer teeth. Adjusted mean serum albumin levels were low in Q1. The associations between the number of teeth and dietary intake were more evident in individuals with a low SES.
CONCLUSIONS
Having few remaining teeth was associated with a low nutrient intake and low serum albumin levels in middle-aged and older Japanese adults, and these associations were more evident in individuals with low SES.
