Introduction
There are approximately 13 million patients with osteoporosis in Japan; however, only 20% of them receive treatment. This study compared the 4‐year continuation rates of osteoporosis ...drugs at different dosing intervals across throughout Japan.
Materials and methods
Receipt data were analyzed to determine the continuation of osteoporosis medication in patients who began treatment at 210 hospitals throughout Japan between October 2016 and September 2017. Continuation rates were compared using Kaplan–Meier curves and log‐rank tests.
Results
The 4‐year continuation rates of daily, weekly, monthly, semi‐annual, and yearly medications nationwide were 8.6%, 16.5%, 13.5%, 31.0%, and 26.0%, respectively. The 4‐year continuation rates for semi‐annual and yearly drugs were significantly higher than daily, weekly, monthly drugs.
Conclusion
Throughout Japan, the 4‐year treatment continuation rates of daily, weekly, monthly, semi‐annual, and yearly osteoporosis drugs all decreased over time. However, the continuation rates of semi‐annual and yearly drugs in the fourth year were significantly higher than those for the other dosing regimens. Therefore, injectable drugs with dosing intervals ≥6 months may improve continuation rates of osteoporosis drugs. Geriatr Gerontol Int 2023; 23: 665–670.
In various regions of Japan, the 4‐year treatment continuation rates of daily, weekly, monthly, semi‐annual, and yearly drugs of osteoporosis drugs with different dosing intervals decreased over time. However, the continuation rates of semi‐annual and yearly drugs in the fourth year were significantly higher than those of the other drugs.

The usefulness of vascular function tests for management of patients with a history of coronary artery disease is not fully known.
We measured flow-mediated vasodilation (FMD) and brachial-ankle ...pulse wave velocity (baPWV) in 462 patients with coronary artery disease for assessment of the predictive value of FMD and baPWV for future cardiovascular events in a prospective multicenter observational study. The first primary outcome was coronary events, and the second primary outcome was a composite of coronary events, stroke, heart failure, and sudden death. During a median follow-up period of 49.2 months, the first primary outcome occurred in 56 patients and the second primary outcome occurred in 66 patients. FMD above the cutoff value of 7.1%, derived from receiver-operator curve analyses for the first and second primary outcomes, was significantly associated with lower risk of the first (hazard ratio, 0.27; 95% confidence interval, 0.06-0.74;
=0.008) and second (hazard ratio, 0.32; 95% confidence interval, 0.09-0.79;
=0.01) primary outcomes. baPWV above the cutoff value of 1731 cm/s was significantly associated with higher risk of the first (hazard ratio, 1.86; 95% confidence interval, 1.01-3.44;
=0.04) and second (hazard ratio, 2.19; 95% confidence interval, 1.23-3.90;
=0.008) primary outcomes. Among 4 groups stratified according to the combination of cutoff values of FMD and baPWV, stepwise increases in the calculated risk ratio for the first and second primary outcomes were observed.
In patients with coronary artery disease, both FMD and baPWV were significant predictors of cardiovascular events. The combination of FMD and baPWV provided further cardiovascular risk stratification.

The usefulness of brachial-ankle pulse wave velocity (baPWV), an index of arterial stiffness, is not fully known for the management of treated hypertensive patients with a history of coronary artery ...disease (CAD) who have blood pressure less than 130/80 mmHg, a recommended blood pressure target in the updated major hypertension guidelines. We analyzed data for 447 treated hypertensive patients with CAD enrolled in FMD-J Study A for assessment of the predictive value of baPWV for future cardiovascular events. The primary outcome was a composite of coronary events, stroke, heart failure, and sudden death. During a median follow-up period of 47.6 months, the primary outcome occurred in 64 patients. Blood pressure less than 130/80 mmHg was significantly associated with a lower risk of the composite outcome independent of other cardiovascular risk factors in treated hypertensive patients with CAD (hazard ratio, 0.59; 95% confidence interval (CI), 0.35-0.99; P = 0.04). In treated hypertensive patients with CAD who had blood pressure less than 130/80 mmHg, baPWV above the cutoff value of 1731 cm/s, derived from receiver-operator characteristic curve analysis for the composite outcome was significantly associated with a higher risk of the composite outcome independent of conventional risk factors (hazard ratio, 2.83; 95% CI, 1.02-7.91; P = 0.04). baPWV was an independent predictor of cardiovascular events in treated hypertensive patients with CAD who had blood pressure less than 130/80 mmHg, for whom measurement of baPWV is recommended for cardiovascular risk assessment.

Baseline brachial artery (BBA) diameter has been reported to be a potential confounding factor of flow-mediated vasodilation (FMD). The purpose of this study was to evaluate the relationships between ...BBA diameter and cardiovascular risk factors and compare the diagnostic accuracy of BBA diameter in subjects without cardiovascular risk factors and patients with cardiovascular disease (CVD) with that of FMD.
We measured BBA diameter and FMD in 5695 male subjects. In addition, we retrospectively investigated the incidence of cardiovascular events using another population sample consisting of 440 male subjects, to compare the accuracy of BBA diameter with that of FMD in predicting cardiovascular events.
BBA diameter and FMD significantly correlated with age, body mass index, systolic blood pressure, diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol, and glucose as well as Framingham risk score. The prevalence of cardiovascular risk factors and CVD increased with the increase in BBA diameter and FMD. Area under the curve (AUC) value of the receiver operating characteristic (ROC) curve for BBA diameter to diagnose subjects without cardiovascular risk factors (0.59 vs. 0.62, p = 0.001) or patients with CVD (0.58 vs. 0.64, p < 0.001) was significantly lower than that for FMD. In the retrospective study, the AUC value of the ROC curve for BBA diameter to predict first major cardiovascular events was significantly lower than that of FMD (0.50 vs. 0.62, p = 0.03).
In men, BBA diameter was inferior to FMD for assessment of cardiovascular risk.
•Baseline brachial artery (BBA) diameter was associated with cardiovascular (CV) risk.•Flow-mediated vasodilation (FMD) was also associated with CV risk.•In men, diagnostic accuracy of BBA diameter for CV risk was inferior to that of FMD.•BBA diameter was inferior to FMD as a predictor of future cardiovascular events.

Hypertension is associated with endothelial dysfunction. Blood pressure significantly correlates with endothelial function in antihypertensive drug-naive subjects. The purpose of this study was to ...determine whether treatment status affects the relationship between blood pressure and endothelial function. We measured flow-mediated vasodilation (FMD) in 2297 subjects, including 1822 antihypertensive drug-naive subjects and 475 treated hypertensive patients. FMD significantly decreased in relation to increase in systolic blood pressure (8.2±3.1% in subjects with systolic blood pressure of <120 mm Hg, 7.5±2.8% for 120–129 mm Hg, 7.1±2.8% for 130–139 mm Hg, and 6.7±2.6% for ≥140 mm Hg; P<0.001). Systolic blood pressure was independently associated with FMD in untreated subjects. In contrast, there was no significant relationship between systolic blood pressure and FMD in treated hypertensive patients (4.6±3.1% in treated hypertensives with systolic blood pressure of <120 mm Hg, 4.8±2.7% for 120–129 mm Hg, 4.9±2.8% for 130–139 mm Hg, and 4.5±2.3% for ≥140 mm Hg; P=0.77). Propensity score matching analysis revealed that the prevalence of endothelial dysfunction defined as FMD of less than the division point for the lowest tertile, and the middle tertile of FMD was significantly higher in treated hypertensive patients than in untreated subjects in all systolic blood pressure categories. Endothelial function assessed by FMD was impaired regardless of the level of blood pressure achieved by antihypertensive drug treatment in hypertensive patients.
In chemosensory systems, a variety of lipophilic ligand-binding proteins have been found in saliva or nasal mucus. Lipophilic stimulants reach the receptor membrane, carried by these proteins. An ...acidic 14-kDa protein purified in the blowfly, Phormia regina, belongs to the insect pheromone-binding protein superfamily, but unlike other lipophilic ligand-binding proteins in insect or vertebrate chemosensory systems, it was distributed in both taste and olfactory organs. A similar protein was also isolated in Drosophila melanogaster. Considering their distributions, cDNA sequences and structural features, we concluded that these proteins belong to a unique subfamily whose members have convergently evolved for a common function required for both senses of taste and olfaction. By an electrophysiological experiment using antiserum, we also suggested that these proteins carry fragrant components of natural foods in taste systems as well as in olfactory systems.
