The effect of mild depression on blood pressure (BP) was assessed in 116 Japanese (32–79 years). As compared to non-depressive (Geriatric Depression Scale, GDS-15 score <5) subjects, mild depressives (GDS-15 score: 1–15) had shorter sleep duration (p = 0.021), lower subjective quality of life (health: p = 0.016; life satisfaction: p < 0.001; and happiness: p < 0.001), and higher 7-d systolic BP (p < 0.05). “Masked non-dipping” (dipping on day 1, but non-dipping on at least 1 of the following 6 d) was more frequent among depressive than non-depressive normotensives (p = 0.008). Among-day BP variability may underlie cardiovascular disease accompanying a key component of psychological depression.

... Previous similar studies also used Comprehensive Geriatric Assessment to screen the related factors of cognitive impairment, and the results showed that cognitive decline was signi cantly correlated with ADL decline, age, upper and lower limb dysfunction, urinary system dysfunction, and especially closely associated with ADL decline (9). In a related study, the Comprehensive Geriatric Assessment was performed in community older adults to screen for cognitive impairment, and central blood pressure and standing and walking tests were associated with cognitive impairment (37). ...

... 20 Presently, association studies between depressive symptoms and home BP have been limited to populations with hypertension 21,22 and 2 general population samples of Japanese adults, with incongruent results. 23,24 None seem to have used home BP readings collected for longer than 4 weeks. Thus, we aimed to investigate the association between depressive symptoms and home BP measured for up to 1 year in a large, community-based cohort, the electronic Framingham Heart Study (eFHS). ...

... The acrophase is defined as the phase of the maximum assumed by the fitted cosine curve in relation to local midnight, used as reference time, as reported earlier. [57][58][59][60][61] The morning surge in SBP was defined as the difference between SBP at the time corresponding to the 12-hour morning acrophase and the SBP MESOR (24-hour average of the 7-day/24-hour record). Likewise, the evening surge in SBP was defined as the difference between SBP at the time corresponding to the 12-hour evening acrophase and the SBP MESOR. ...

With Mikhail and Olga Blank and Daria Denisova, we assessed the relative prominence of the circadian and half-weekly variation in temperature and pulse and found that it predicted cancer recurrence in their population of patients.

... was to determine how effectively the wellbeing of elderly citizens can be supported with a small investment. After visiting Uraus twice a year for 20 years (from 2000 to 2019) to educate its citizens regarding health promotion, providing every-day life advice on food, exercise and sleep, significant improvement was achieved in terms of blood pressure, diabetes and depressive mood, among others, as reported previously [1][2][3][4][5][6]. As a result, cost of care for the elderly was lower [7]. ...

... In records spanning 2 days, the quiet and disturbed days were defined as those 24 h days with the lowest or highest geomagnetic activity. This definition is the same as that used in our previous studies of HRV in Alta and in space [18,[70][71][72]. In the two records spanning 5 days or longer, moderate and extreme geomagnetic disturbances correspond to geomagnetic activity 3 or 12 times higher than on quiet days, respectively. ...

... Increased a 1 values during active standing are consistent with predominant sympathetic activity, and it is in agreement with experimental studies that showed increased a 1 during parasympathetic blockade with atropine (Penttila et al., 2003;Perkiomaki et al., 2002;Tulppo et al., 2001b). Previous studies showed that a 1 increases in response to passive induced orthostatic stress (i.e., HUTT), in both healthy subjects and vasovagal syncope patients (Kubo et al., 2003;Tulppo et al., 2001a). This study shows that such increment in a 1 is significantly larger in 1HUTT patients, implying that they had a larger decrease in complexity of HRV. ...

... However, a reduction in nailfold capillary blood velocity was noted to occur, especially in the evening hours. Another small study in which three healthy men were exposed to an artificial field mimicking the amplitude (50 nT) and frequency (1.6 MHz) of a geomagnetic storm also failed to find changes in BP [72]. In this study, exposure was during 12 consecutive weekends with BP measured every 30 minutes during exposure. ...
