High Parity Is an Independent Risk Factor for Tooth Loss in Women: A Community-Based Takahata Study in Japan.
Risk factors for tooth loss have been widely examined previously. However, no previous study has comprehensively investigated the risk factors, including lifestyle-related specific factors (parity, oral health habits, and socioeconomic status), for fewer than 20 teeth among women in the general population in Japan. This cross-sectional study explored the association of these risk factors, especially parity, with having fewer than 20 teeth among Japanese women. ⋯ Our study is the largest-scale study of the general female population in Japan and the first study to comprehensively investigate risk factors (parity, oral health status, and socioeconomic status) for fewer than 20 teeth. We thus found that higher parity, especially, two or more, was independent risk factors for having less than 20 teeth among Japanese women. In conclusion, the present study emphasizes the importance of good oral health habits in women, especially, during pregnancy and in the postpartum period, to maintain 20 or more teeth.

Eating Fast and Until Full Is Associated with Elevated Alanine Aminotransferase Activity in Japanese Schoolchildren: A Cross-Sectional Study.
Alanine aminotransferase (ALT) activity has been recognized as a marker for monitoring the risk of metabolic syndrome, diabetes and non-alcoholic fatty liver disease in children. Higher ALT activity was reported to be associated with eating fast in Japanese adults, but the association in children is unclear. Moreover, eating fast and eating until full are reported to be associated with being overweight. ⋯ In conclusion, "eating fast and eating until full" was associated with elevated ALT in schoolchildren. A sex difference in the association of "eating fast and not eating until full" with elevated ALT was observed. Modifying the behaviors of eating fast and eating until full is important for schoolchildren to prevent ALT elevation.

Optimal Cutoff Values of the Alcohol Use Disorders Identification Test and its Short Version for Detecting Excessive Alcohol Use in Japanese College Students.
Alcohol use disorder is a serious health problem in college students. Alcohol Use Disorders Identification Test (AUDIT) is a 10-item screening tool to assess alcohol consumption, drinking behaviors, and alcohol-related problems. AUDIT-C is a short version of AUDIT, consisting of consumption items 1-3. ⋯ ROC (receiver operating characteristic) curve analysis showed that the optimal cutoff values for moderate drinking, heavy drinking and binge drinking were 5, 8 and 5 for men and 4, 7 and 4 for women in AUDIT; and 4, 7 and 4 for men and 4, 7 and 4 for women in AUDIT-C, respectively. Moderate drinking is considered unsafe drinking. Therefore, the optimal cutoff values for moderate drinking (5 for men and 4 for women in AUDIT and 4 for both sexes in AUDIT-C) are important parameters for prevention of alcohol use disorder in Japanese college students.

Appendicular Skeletal Muscle Mass Correlates with Patient-Reported Outcomes and Physical Performance in Patients with Idiopathic Pulmonary Fibrosis.
Idiopathic pulmonary fibrosis (IPF), an incurable lung disease of unknown cause, often presents with losses of skeletal muscle mass. IPF requires comprehensive care, but it has not been investigated which skeletal muscle mass index reflects holistic management factors: pulmonary function, patient-reported outcomes (PROs), and physical performance. We compared three representative indices of skeletal muscle mass with holistic management factors in IPF patients. ⋯ PMCSA showed the next greatest number of correlations, with peripheral muscle strength, 6MWD, and mMRC, whereas ESMCSA showed no significant correlations with any index. Thus, ASMI correlated with both PROs and physical performance, and PMCSA correlated mainly with physical performance. In conclusion, assessing ASMI is helpful for the comprehensive care of patients with IPF.

Observational StudyUrinary Thrombin as a Marker of Glomerular Inflammation Associated with Renal Injury in Type 2 Diabetes.
Glomerular inflammation is a putative aggravation factor for type 2 diabetic nephropathy and urinary thrombin is a novel marker of glomerular inflammation. To clarify the relationship between glomerular inflammation and progression of the nephropathy, we measured urinary thrombin in 118 patients with type 2 diabetic nephropathy at different stages. To investigate the implications of urinary thrombin in the nephropathy, we compared urinary thrombin with expression of tissue factor, the trigger of blood coagulation activation, in glomeruli and with markers of renal injury (estimated glomerular filtration rate (eGFR) and proteinuria). ⋯ Urinary thrombin was significantly associated with both decreased eGFR and increased proteinuria in type 2 diabetic nephropathy. Therefore, increased urinary thrombin in patients with advanced stages of type 2 diabetic nephropathy suggests that glomerular inflammation may injure the tissues, thereby impairing renal function. Monitoring an effect of anti-diabetic treatments on glomerular inflammation in the patients with type 2 diabetic nephropathy may be a possible application of urinary thrombin.
