    Abstract To measure blood pressure precisely and make the data comparable among facilities, measurement methods and devices must be standardized. Since the Minamata Convention on Mercury, there is no metrological standard for sphygmomanometers. The current validation methods recommended by non-profit organizations in Japan, the US, and European Union countries are not necessarily applicable to the clinical setting, and no protocol for daily or routine performance of quality control has been defined. In addition, recent rapid technological advances have enabled monitoring blood pressure at home with wearable devices or without a cuff by using a smartphone app. A clinically relevant validation method for this recent technology is not available. The importance of out-of-office blood pressure measurement is highlighted by guidelines for the diagnosis and treatment of hypertension, but an appropriate protocol for validating a device is required.

    Abstract It has been more than 60 years since the colonized genetic model of hypertension was first established. Model animals contribute greatly to the advance of understanding of the pathophysiology and development of effective therapy. In this review, the author focuses on two points: gene-related biomarkers and the use of humanized mice to search for biomarkers. First, the author provides an overview of the history of the establishment of hypertension and salt-sensitivity model rats, as well as advances in genetic analysis of causative genes of hypertension and the theory of renal causes of salt-sensitive hypertension. The recent animal model analysis adds the notion of the importance of epigenetic alterations in addition to the genetic causes of hypertension. Both germline mutations and epigenetic analysis of congenic animal models are complementary and should carry out furtherly. Among epigenetic factors, non-coding RNA is a promising new 'liquid biopsy' which is originally applied to diagnose cancers by detecting cancer cell-derived DNA, RNA, or other molecules in a person's body fluid and now it can be applied to any pathophysiological conditions. Then, the author reviews the usefulness of humanized mice. Few studies have used such mice in cardiovascular research, but the present study highlights a study of immune-related disease and the search for biomarkers in such mice. Perspectives on using humanized mice in cardiovascular research are discussed.

    Abstract Background: The urine protein dipstick test is widely used, but false-positive and false-negative results may occur. This study aimed to compare the urine protein dipstick test with a urine protein quantification method.
    Methods: The data were extracted using the Abbott Diagnostic Support System, which analyzes the inspection results using multiple parameters. This study included 41,058 specimens tested using the urine dipstick test and protein creatinine ratio from patients aged ≥18 years. The proteinuria creatinine ratio was classified according to the Kidney Disease Outcomes Quality Initiative guidelines.
    Results: Urine protein on the dipstick test was negative in 15,548 samples (37.9%), trace in 6,422 samples (15.6%), and ≥1+ in 19,088 samples (46.5%). Among the trace proteinuria samples, A1 (<0.15 g/gCr), A2 (0.15-0.49 g/gCr), and A3 (≥0.5 g/gCr) category proteinuria accounted for 31.2, 44.8, and 24.0% of samples, respectively. All trace proteinuria specimens with a specific gravity of <1.010 were classified as A2 and A3 category proteinuria. In the trace proteinuria cases, women had a lower specific gravity and a higher percentage of A2 or A3 category proteinuria than men. The sensitivity in the "dipstick proteinuria" ≥ trace" group was higher than that in the "dipstick proteinuria ≥ 1+" group within the lower specific gravity group. The sensitivity in the "dipstick proteinuria ≥ 1+" group was higher for men than for women, and the sensitivity in the "dipstick proteinuria ≥ trace" group was higher than that in the "dipstick proteinuria ≥ 1+" group for women.
    Conclusion: Pathological proteinuria assessment requires caution; this study suggests that evaluating the specific gravity of urine specimens with trace proteinuria is essential. Particularly for women, the sensitivity of the urine dipstick test is low, and caution is needed even with trace specimens.
