Active Inference With Empathy Mechanism for Socially Behaved Artificial Agents in Diverse Situations.

This article proposes a method for an artificial agent to behave in a social manner. Although defining proper social behavior is difficult because it differs from situation to situation, the agent following the proposed method adaptively behaves appropriately in each situation by empathizing with the surrounding others. The proposed method is achieved by incorporating empathy into active inference. We evaluated the proposed method regarding control of autonomous mobile robots in diverse situations. From the evaluation results, an agent controlled by the proposed method could behave more adaptively socially than an agent controlled by the standard active inference in the diverse situations. In the case of two agents, the agent controlled with the proposed method behaved in a social way that reduced the other agent's travel distance by 13.7% and increased the margin between the agents by 25.8%, even though it increased the agent's travel distance by 8.2%. Also, the agent controlled with the proposed method behaved more socially when it was surrounded by altruistic others but less socially when it was surrounded by selfish others.

Nighttime Blood Pressure Phenotype and Cardiovascular Prognosis: Practitioner-Based Nationwide JAMP Study.

BACKGROUND: Ambulatory and home blood pressure (BP) monitoring parameters are better predictors of cardiovascular events than are office BP monitoring parameters, but there is a lack of robust data and little information on heart failure (HF) risk. The JAMP study (Japan Ambulatory Blood Pressure Monitoring Prospective) used the same ambulatory BP monitoring device, measurement schedule, and diary-based approach to data processing across all study centers and determined the association between both nocturnal hypertension and nighttime BP dipping patterns and the occurrence of cardiovascular events, including HF, in patients with hypertension. METHODS: This practitioner-based, nationwide, multicenter, prospective, observational study included patients with at least 1 cardiovascular risk factor, mostly hypertension, and free of symptomatic cardiovascular disease at baseline. All patients underwent 24-hour ambulatory BP monitoring at baseline. Patients were followed annually to determine the occurrence of primary end point cardiovascular events (atherosclerotic cardiovascular disease and HF). RESULTS: A total of 6,359 patients (68.6±11.7 years of age, 48% men) were included in the final analysis. During a mean±SD follow-up of 4.5±2.4 years, there were 306 cardiovascular events (119 stroke, 99 coronary artery disease, 88 HF). Nighttime systolic BP was significantly associated with the risk of atherosclerotic cardiovascular disease and HF (hazard ratio adjusted for demographic and clinical risk factors per 20-mm Hg increase: 1.18 [95% CI, 1.02-1.37], P=0.029; and 1.25 [95% CI, 1.00-1.55], P=0.048, respectively). Disrupted circadian BP rhythm (riser pattern, nighttime BP higher than daytime BP) was significantly associated with higher overall cardiovascular disease risk (1.48 [95% CI, 1.05-2.08]; P=0.024), and especially HF (2.45 [95% CI, 1.34-4.48]; P=0.004) compared with normal circadian rhythm. CONCLUSIONS: Nighttime BP levels and a riser pattern were independently associated with the total cardiovascular event rate, in particular for HF. These findings suggest the importance of antihypertensive strategies targeting nighttime systolic BP. Registration: URL: https://www.umin.ac.jp/ctr/; Unique identifier: UMIN000020377.

Autonomic dysreflexia associated with cervical spinal cord gliofibroma: case report.

BACKGROUND: Autonomic dysreflexia (AD) is an abnormal reflex of the autonomic nervous system normally observed in patients with spinal cord injury from the sixth thoracic vertebra and above. AD causes various symptoms including paroxysmal hypertension due to stimulus. Here, we report a case of recurrent AD associated with cervical spinal cord tumor. CASE PRESENTATION: The patient was a 57-year-old man. Magnetic resonance imaging revealed an intramedullary lesion in the C2, C6, and high Th12 levels. During the course of treatment, sudden loss of consciousness occurred together with abnormal paroxysmal hypertension, marked facial sweating, left upward conjugate gaze deviation, ankylosis of both upper and lower extremities, and mydriasis. Seizures repeatedly occurred, with symptoms disappearing after approximately 30 min. AD associated with cervical spinal cord tumor was diagnosed. Histological examination by tumor biopsy confirmed the diagnosis of gliofibroma. Radiotherapy was performed targeting the entire brain and spinal cord. The patient died approximately 3 months after treatment was started. CONCLUSIONS: AD is rarely associated with spinal cord tumor, and this is the first case associated with cervical spinal cord gliofibroma. AD is important to recognize, since immediate and appropriate response is required.

Sex Differences in the Prognostic Power of Brain Natriuretic Peptide and N-Terminal Pro-Brain Natriuretic Peptide for Cardiovascular Events　- The Japan Morning Surge-Home Blood Pressure Study.

BACKGROUND: Brain natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are prognostic biomarkers. Although these 2 peptides differ with regard to biological characteristics, there are few reports on the differences between BNP and NT-proBNP with regard to cardiovascular events or according to sex.Methods and Results:Between 2005 and 2012, this study analyzed 3,610 of 4,310 Japanese outpatients (mean age, 65 years; men, n=1,664; women, n=1,947) with a history of at least one cardiovascular event who were recruited to the Japan Morning Surge-Home Blood Pressure Study. During an average 4-year follow-up, there were 129 cardiovascular events. Both median BNP (21.1 pg/mL; IQR, 10.9-40.6 pg/mL vs. 16.2 pg/mL, IQR, 7.2-36.2 pg/mL, P<0.001) and median NT-proBNP (54.7 pg/mL; IQR, 30.2-102.6 pg/mL vs. 44.9 pg/mL, IQR, 20.7-92.6 pg/mL, P<0.001) were significantly higher in women than in men. A 1-SD increment in log-transformed BNP (hazard ratio [HR], 2.18; 95% CI: 1.53-3.10) and NT-proBNP (HR, 2.39; 95% CI: 1.73-3.31) was associated with a significant increase in cardiovascular events in women; in men, only NT-proBNP showed this association. There was an interaction between log-transformed BNP (P=0.007) or NT-proBNP (P=0.001) and cardiovascular events according to sex. CONCLUSIONS: Both BNP and NT-proBNP predicted cardiovascular outcomes in a large Japanese clinical population. BNP and NT-proBNP were significantly stronger predictors in women than in men.

Comparison of ambulatory blood pressure-lowering effects of higher doses of different calcium antagonists in uncontrolled hypertension: the Calcium Antagonist Controlled-Release High-Dose Therapy in Uncontrolled Refractory Hypertensive Patients (CARILLON) Study.

BACKGROUND: Data are sparse regarding ambulatory blood pressure (BP) reduction of up-titration from a standard dose to a high dose in both nifedipine controlled-release (CR) and amlodipine. This was a prospective, randomized, multicenter, open-label trial. PATIENTS AND METHODS: Fifty-one uncontrolled hypertensives medicated by two or more antihypertensive drugs including a renin-angiotensin system inhibitor and a calcium antagonist were randomly assigned to either the nifedipine CR (80 mg)/candesartan (8 mg) group or the amlodipine (10 mg)/candesartan (8 mg) group. RESULTS: The changes in 24-hr BP were comparable between the groups. The nifedipine group demonstrated a significant decrease in their urinary albumin creatinine ratio, whereas the amlodipine group demonstrated a significant decrease in their NTproBNP level. However, there was no significant difference in any biomarkers between the two groups. CONCLUSION: Nifedipine showed an almost equal effect on ambulatory blood pressure as amlodipine. Their potentially differential effects on renal protection and NTproBNP should be tested in larger samples.

Late-spiking retrosplenial cortical neurons are not synchronized with neocortical slow waves in anesthetized mice.

Neocortical slow waves are critical for memory consolidation. The retrosplenial cortex is thought to facilitate the slow wave propagation to regions beyond the neocortex. However, it remains unclear which population is responsible for the slow wave propagation. To address this issue, we performed in vivo whole-cell recordings to identify neurons that were synchronous and asynchronous with slow waves. By quantifying their intrinsic membrane properties, we observed that the former exhibited regular spiking, whereas the latter exhibited late spiking. Thus, these two cell types transmit information in different directions between the neocortex and subcortical regions.

Mixbiotic society measures: Assessment of community well-going as living system.

Social isolation and fragmentation represent global challenges, with the former stemming from a lack of interaction and the latter from exclusive mobs-both rooted in communication issues. Addressing these challenges, the philosophical realm introduces the concept of the "mixbiotic society." In this framework, individuals with diverse freedoms and values mix together in physical proximity with diverse mingling, recognizing their respective "fundamental incapacities" and uniting in solidarity. This study aims to provide novel measures to balance freedom and solidarity, specifically the intermediate between isolation and mobbing, within a mixbiotic society. To achieve this, we introduce simplified measures to evaluate dynamic communication patterns. These measures complement traditional social network analysis of static structures and conventional entropy-based assessments of dynamic patterns. Our specific hypothesis posits that the measures corresponding to four distinct phases are established by representing communication patterns as multidimensional vectors. These measures include the mean of Euclidean distance to quantify "mobism" for fragmentation, the relative distance change for "atomism" indicating isolation, and a composite measure derived from multiplying the mean and variance of cosine similarity for "mixism," reflecting the well-going state of a mixbiotic society. Additionally, nearly negligible measures correspond to "nihilism." Through the evaluation of seven real-society datasets (high school, primary school, workplace, village, conference, online community, and email), we demonstrate the utility of the "mixism" measure in assessing freedom and solidarity in society. These measures can be employed to typify communities on a radar chart and a communication trajectory graph. The superiority of the measures lies in their ability to evaluate dynamic patterns, ease of calculation, and easily interpretable meanings compared to conventional analyses. As a future development, alongside additional validation using diverse datasets, the mixbiotic society measures will be employed to analyze social issues and applied in the fields of digital democracy and platform cooperativism.

Antihypertensive medication persistence and adherence among non-Hispanic Asian US patients with hypertension and fee-for-service Medicare health insurance.

BACKGROUND: Less than 50% of non-Hispanic Asian adults taking antihypertensive medication have controlled blood pressure. METHODS: We compared non-persistence and low adherence to antihypertensive medication between non-Hispanic Asian and other race/ethnicity groups among US adults ≥66 years who initiated antihypertensive medication between 2011 and 2018 using a 5% random sample of Medicare beneficiaries (non-Hispanic Asian, n = 2,260; non-Hispanic White, n = 56,000; non-Hispanic Black, n = 5,792; Hispanic, n = 4,212; and Other, n = 1,423). Non-persistence was defined as not having antihypertensive medication available to take in the last 90 of 365 days following treatment initiation. Low adherence was defined as having antihypertensive medication available to take on <80% of the 365 days following initiation. RESULTS: In 2011-2012, 2013-2014, 2015-2016 and 2017-2018, the proportion of non-Hispanic Asian Medicare beneficiaries with non-persistence was 29.1%, 25.6%, 25.4% and 26.7% (p-trend = 0.381), respectively, and the proportion with low adherence was 58.1%, 54.2%, 53.4% and 51.6%, respectively (p-trend = 0.020). In 2017-2018, compared with non-Hispanic Asian beneficiaries, non-persistence was less common among non-Hispanic White beneficiaries (risk ratio 0.74 [95%CI, 0.64-0.85]), non-Hispanic Black beneficiaries (0.80 [95%CI 0.68-0.94]) and those reporting Other race/ethnicity (0.68 [95%CI, 0.54-0.85]) but not among Hispanic beneficiaries (1.04 [95%CI, 0.88-1.23]). Compared to non-Hispanic Asian beneficiaries, non-Hispanic White beneficiaries and beneficiaries reporting Other race/ethnicity were less likely to have low adherence to antihypertensive medication (relative risk 0.78 [95%CI 0.72-0.84] and 0.84 [95%CI 0.74-0.95], respectively); there was no association for non-Hispanic Black or Hispanic beneficiaries. CONCLUSIONS: Non-persistence and low adherence to antihypertensive medication were more common among older non-Hispanic Asian than non-Hispanic White adults.

Concept, study design, and baseline nighttime blood pressure control status of the WISDOM-Night Study using a wrist-type oscillometric home blood pressure monitoring device.

There is growing evidence that nocturnal hypertension is an independent risk factor for cardiovascular diseases, including heart failure. However, brachial blood pressure (BP) measurements during sleep might themselves disturb sleep quality. We initiated a nationwide, multicenter observational prospective study using a wrist-type oscillometric nighttime BP monitoring device with new algorithms to measure supine BP accurately without sleep disturbance. This study, named the Wrist ICT-based Sleep and Circadian Blood Pressure Monitoring Program-Night BP Study (WISDOM-Night Study), was designed to clarify the impact of wrist-measured daily nighttime BPs on cardiovascular prognosis (stroke, coronary artery disease, heart failure, etc.) using 7 days of BP measurements at 2:00 a.m., 3:00 a.m., 4:00 a.m., and 4 h after bedtime. A total of 2751 patients with one or more cardiovascular risk factors were recruited between March 2021 and March 2024 and are currently being followed up for 7 years. Additionally, 1416 of the WISDOM-Night Study-enrolled patients who also agreed to participate in the WISDOM-Hypertension-Mediated Organ Damage (HMOD) Study underwent echocardiography to evaluate the association between wrist-measured BP and left ventricular structure. Data from this WISDOM-Night Study should provide the prospective association between nighttime BP and cardiovascular disease and reveal the indexes of nighttime BP with clinical pathological relevance. This first report of the WISDOM-Night Study describes the study design, baseline characteristics, and BP control status.

Emodiversity evaluation of remote workers through health monitoring based on intra-day emotion sampling.

Introduction: In recent years, the widespread shift from on-site to remote work has led to a decline in employees' mental health. Consequently, this transition to remote work poses several challenges for both employees and employers. To address these challenges, there is an urgent need for techniques to detect declining mental health in employees' daily lives. Emotion-based health assessment, which examines emotional diversity (emodiversity) experienced in daily life, is a possible solution. However, the feasibility of emodiversity remains unclear, especially from the perspectives of its applicability to remote workers and countries other than Europe and the United States. This study investigated the association between subjective mental health decline and emotional factors, such as emodiversity, as well as physical conditions, in remote workers in Japan. Method: To explore this association, we conducted a consecutive 14-day prospective observational experiment on 18 Japanese remote workers. This experiment comprised pre-and post-questionnaire surveys, physiological sensing, daytime emotion self-reports, and subjective health reports at end-of-day. In daytime emotion self-reports, we introduced smartphone-based experience sampling (also known as ecological momentary assessment), which is suitable for collecting context-dependent self-reports precisely in a recall bias-less manner. For 17 eligible participants (mean ± SD, 39.1 ± 9.1 years), we evaluated whether and how the psycho-physical characteristics, including emodiversity, changed on subjective mental health-declined experimental days after analyzing descriptive statistics. Results: Approximately half of the experimental days (46.3 ± 18.9%) were conducted under remote work conditions. Our analysis showed that physical and emotional indices significantly decreased on mental health-declined days. Especially on high anxiety and depressive days, we found that emodiversity indicators significantly decreased (global emodiversity on anxiety conditions, 0.409 ± 0.173 vs. 0.366 ± 0.143, p = 0.041), and positive emotional experiences were significantly suppressed (61.5 ± 7.7 vs. 55.5 ± 6.4, p < 0.001). Discussion: Our results indicated that the concept of emodiversity can be applicable even to Japanese remote workers, whose cultural background differs from that of individuals in Europe and the United States. Emodiversity showed significant associations with emotion dysregulation-related mental health deterioration, suggesting the potential of emodiversity as useful indicators in managing such mental health deterioration among remote workers.

Usefulness of 3D T1-Turbo Spin Echo Imaging for the Evaluation of Intracranial Stent Placement.

Objective: Evaluation of intracranial stent placement by MRI suffers the problems of signal artifacts during time-of-flight MRA (TOF-MRA). Therefore, angiographic examination is required for detailed intravascular assessment of the stent placement site. Recently, 3D T1-turbo spin echo (3D-TSE) has been developed for evaluation of carotid artery stent placement. We investigated the use of the 3D-TSE imaging method for the evaluation of intracranial vascular stent placement. Methods: The subjects consisted of nine patients who underwent intracranial vascular stent placement between April 2015 and December 2019. Postoperatively, the lumens of the placed stents were measured by TOF-MRA, DSA, and 3D-TSE imaging. Analysis was performed by type of stent and placement site. Results: The stents used were Neuroform Atlas (3 patients), LVIS (3 patients), LVIS Jr (2 patients), and Integrity (1 patient). TOF-MRA of the stent placement site showed defects in the image or poor visualization in all nine patients, whereas 3D-TSE imaging visualized the lumen at the stent indwelling site in all patients. The blood vessel diameter measured by the DSA and 3D-TSE imaging exhibited positive correlations regardless of the stent type and placement site. Conclusion: 3D-TSE imaging allows visualization of the lumen of the site of an intracranial vascular stent, regardless of the type of stent or the vessel. Thus, this method may be useful for evaluating the vascular lumen of a lesion.

Agreement Between Guideline Thresholds Using an "All-in-One" Device to Measure Office, Home, and Ambulatory Blood Pressures.

BACKGROUND: Blood pressure (BP) thresholds for diagnosing and managing hypertension vary for office, home, and ambulatory readings, and between guideline documents. This analysis determined corresponding office, home, and ambulatory BP thresholds using baseline data from the HI-JAMP (Home-Activity Information and Communication Technology-Based Japan Ambulatory Blood Pressure Monitoring Prospective) study, which used a validated "all-in-one" BP monitoring device. METHODS AND RESULTS: Data from 2322 treated patients with hypertension who underwent office BP measurement, then 24-hour ambulatory BP monitoring, then home BP monitoring for 5 days were analyzed. Corresponding BP thresholds for office, home, and ambulatory measurements were determined using Deming regression. Values equivalent to office systolic BP (SBP) of 120 and 140 mm Hg were as follows: 115.9 and 127.7 mm Hg for 24-hour ambulatory SBP; 120.8 and 134.0 mm Hg for daytime ambulatory SBP; 104.9 and 117.9 mm Hg for nighttime ambulatory SBP; and 122.0 and 134.2 mm Hg for morning-evening average home SBP. Deming regression showed that morning-evening average home SBP and daytime ambulatory SBP were almost the same (home SBP=0.99×daytime ambulatory SBP+0.27 mm Hg; r=0.627). Morning-evening average home SBP values of 120 and 135 mm Hg were equivalent to daytime ambulatory SBP values of 119.1 and 133.9 mm Hg, respectively. A home SBP threshold of 130 mm Hg corresponded to 24-hour and nighttime ambulatory SBP values of 123.5 and 113.6 mm Hg, whereas a home SBP threshold of 135 mm Hg corresponded to 24-hour and nighttime ambulatory SBP values of 128.0 and 119.2 mm Hg. CONCLUSIONS: Ambulatory and home BP thresholds in this analysis were similar to those proposed by existing guidelines. The similarity between the home BP and daytime ambulatory BP thresholds was a clinically relevant finding.

Different Home Blood Pressure Thresholds to Predict Perfect 24-Hour Ambulatory Blood Pressure Control in Treated Hypertension Based on an "All-in-One" Device.

BACKGROUND: Home blood pressure (BP) is an important component of digital strategies for hypertension management. However, no studies have used the same device to investigate 24-hour BP control status in relation to different home BP control thresholds. METHODS: Participants in the general practitioner-based, multicenter HI-JAMP study (Home-Activity Information and Communication Technology-Based Japan Ambulatory Blood Pressure Monitoring Prospective) underwent office BP measurement, then 24-hour ambulatory BP monitoring, then home BP monitoring for 5 days. A validated all-in-one BP monitoring device was used to measure office, home, and ambulatory BP. Baseline data were used to investigate ambulatory BP control status in individuals with well-controlled home BP based on the different guideline thresholds (125/75 mm Hg, 130/80 mm Hg, and 135/85 mm Hg). RESULTS: Data from 2269 patients were analyzed. For individuals with well-controlled home BP <135/85 mm Hg (59.5% of the total population), the prevalence of uncontrolled 24-hour (≥130/80 mm Hg), daytime (≥135/85 mm Hg), and nighttime ambulatory BP (≥120/70 mm Hg) was 19.9%, 18.5%, and 33.6%, respectively. Corresponding prevalence rates in the 42.7% of participants with well-controlled home BP <130/80 mm Hg were 13.4%, 12.9%, and 26.0%, and when well-controlled home BP was strictly defined as <125/75 mm Hg (23.9% of the population), prevalence of rates of uncontrolled 24-hour, daytime, and nighttime ambulatory BP were 7.0%, 9.0%, and 15.3%, respectively. CONCLUSIONS: Home BP control status defined using different thresholds could predict 24-hour ambulatory BP control status in treated hypertension. One-third of individuals still had uncontrolled nocturnal hypertension when home BP was controlled to <135/85 mm Hg, but ambulatory BP was quite well controlled when home BP was <125/75 mm Hg.

Nighttime hemodynamic phenotype. A novel risk factor for cardiovascular disease, especially heart failure: the practitioner-based nationwide JAMP study.

BACKGROUND: Non-dipper and riser patterns of nocturnal blood pressure (BP) are risk factors for cardiovascular disease (CVD), including heart failure (HF). However, the risk associated with a disrupted nocturnal pattern of heart rate is not well known. OBJECTIVES: To investigate whether the nighttime heart rate is a risk factor for HF, alongside nighttime BP phenotype. METHODS: The practitioner-based, nationwide, prospective Japan Ambulatory Blood Pressure Monitoring Prospective (JAMP) study included patients with ≥ 1 CVD risk factor but without symptomatic CVD at baseline. All patients underwent 24-h ambulatory BP monitoring at baseline and were followed annually. Nocturnal heart rate dipping (%) was calculated as 100•[1 - nighttime/daytime heart rate]. RESULTS: During a mean 4.5 years' follow-up in 6,359 patients (mean age 68.6 years), there were 306 CVD events (119 stroke, 99 coronary artery disease, and 88 HF). A 10-beats/min increase in nighttime heart rate was significantly associated with a 36-47% increase in the risk of total CVD, stroke and HF events independently of office SBP and nighttime SBP (all p < 0.005). The CVD and HF risk associated with nocturnal heart rate dipping status was independent of office and 24-h systolic BP and nocturnal BP dipping status (p < 0.001). Performance of the final model for predicting HF including BP parameters was significantly improved by the addition of nocturnal heart rate dipping patterns (p = 0.038; C-statistic 0.852). CONCLUSION: Nighttime non-dipper and riser patterns of heart rate were associated with CVD especially HF, independently and additively of nocturnal BP dipping status, indicating the importance of antihypertensive strategies targeting nighttime hemodynamics.

A case of facial nerve palsy caused by severe head injury treated by translabyrinthine approach.

Background: Several treatments for traumatic facial paralysis have been reported, but the role of surgery is still controversial. Case Description: A 57-year-old man was admitted to our hospital with head trauma due to a fall injury. A total body computed tomography (CT) scan showed a left frontal acute epidural hematoma associated with a left optic canal and petrous bone fractures with the disappearance of the light reflex. Hematoma removal and optic nerve decompression were performed immediately. The initial treatment was successful with complete recovery of consciousness and vision. The facial nerve paralysis (House and Brackmann scale grade 6) did not improve after medical therapy, and thus, surgical reconstruction was performed 3 months after the injury. The left hearing was lost entirely, and the facial nerve was surgically exposed from the internal auditory canal to the stylomastoid foramen through the translabyrinthine approach. The facial nerve's fracture line and damaged portion were recognized intraoperatively near the geniculate ganglion. The facial nerve was reconstructed using a greater auricular nerve graft. Functional recovery was observed at the 6-months follow-up (House and Brackmann grade 4), with significant recovery in the orbicularis oris muscle. Conclusion: Interventions tend to be delayed, but it is possible to select a treatment method of the translabyrinthine approach.

Use of Different Blood Pressure Thresholds to Reduce the Number of Home Blood Pressure Monitoring Days Needed for Detecting Hypertension.

BACKGROUND: Home blood pressure (BP) monitoring over a 7-day period is recommended to confirm the diagnosis of hypertension. METHODS: We determined upper and lower home BP thresholds with >90% positive predictive value and >90% negative predictive value using 1 to 6 days of monitoring to identify high home BP (systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg) based on 7 days of home BP monitoring. The sample included 361 adults from the Improving the Detection of Hypertension Study who were not taking antihypertensive medication. We used two 7-day periods, at least 3 days apart, the first being a sampling period and the second a reference period. For each number of days in the sampling period, we determined the percentage of participants who had a high likelihood of having (>90% positive predictive value) or not having (>90% negative predictive value) high BP and would not need to continue home BP monitoring. Only the participants in an uncertain category (ie, positive predictive value ≤90% and negative predictive value ≤90%) after each day were carried forward to the next day of home BP monitoring. RESULTS: Of the 361 participants (mean [SD] age of 41.3 [13.2] years; 60.4% women), 38.0% had high home BP during the reference period. There were 63.7%, 17.1%, 10.5%, 3.3%, 3.6%, and 1.4% participants who would not need to continue after 1, 2, 3, 4, 5, and 6 days of monitoring. CONCLUSIONS: In most people, high home BP can be identified or excluded with a high degree of confidence with 3 days or less of monitoring.

Diagnostic Accuracy of Office Blood Pressure Measurement and Home Blood Pressure Monitoring for Hypertension Screening Among Adults: Results From the IDH Study.

BACKGROUND: Using high awake blood pressure (BP; ≥130/80 mm Hg) on ambulatory BP monitoring (ABPM) as a reference, the purpose of this study was to determine the accuracy of high office BP (≥130/80 mm Hg) at an initial visit and high confirmatory office BP (≥130/80 mm Hg), and separately, high home BP (≥130/80 mm Hg) among participants with high office BP (≥130/80 mm Hg) at an initial office visit. METHODS AND RESULTS: The accuracy of office BP measurements using the oscillometric method for detecting high BP on ABPM was determined among 379 participants with complete office BP and ABPM data in the IDH (Improving the Detection of Hypertension) study. For detecting high BP on ABPM, the accuracy of high confirmatory office BP using the oscillometric method and, separately, high home BP was also determined among the subgroup of 122 participants with high office BP at an initial visit and complete home BP monitoring data. High office BP had moderate sensitivity (0.61 [95% CI, 0.53-0.68]) and high specificity (0.85 [95% CI, 0.80-0.90]) for high awake BP. High confirmatory office BP and high home BP had moderate sensitivity (0.69 [95% CI, 0.59-0.79] and 0.79 [95% CI, 0.71-0.87], respectively) and low and moderate specificity (0.44 [95% CI, 0.27-0.61] and 0.72 [95% CI, 0.56-0.88], respectively). CONCLUSIONS: Many individuals with high BP on ABPM do not have high office BP. Confirmatory office BP and home blood pressure monitoring also had limited ability to identify individuals with high BP on ABPM.

Inconsistent Control Status of Office, Home, and Ambulatory Blood Pressure All Taken Using the Same Device: The HI-JAMP Study Baseline Data.

BACKGROUND: Inconsistencies between the office and out-of-office blood pressure (BP) values (described as white-coat hypertension or masked hypertension) may be attributable in part to differences in the BP monitoring devices used. METHODS: We studied consistency in the classification of BP control (well-controlled BP vs. uncontrolled BP) among office, home, and ambulatory BPs by using a validated "all-in-one" BP monitoring device. In the nationwide, general practitioner-based multicenter HI-JAMP study, 2,322 hypertensive patients treated with antihypertensive drugs underwent office BP measurements and 24-hour ambulatory BP monitoring (ABPM), consecutively followed by 5-day home BP monitoring (HBPM), for a total of seven BP measurement days. RESULTS: Using the thresholds of the JSH2019 and ESC2018 guidelines, the patients with consistent classification of well-controlled status in the office (<140 mmHg) and home systolic BP (SBP) (<135 mmHg) (n = 970) also tended to have well-controlled 24-hour SBP (<130 mmHg) (n = 808, 83.3%). The patients with the consistent classification of uncontrolled status in office and home SBP (n = 579) also tended to have uncontrolled 24-hour SBP (n = 444, 80.9%). Among the patients with inconsistent classifications of office and home BP control (n = 803), 46.1% had inconsistent ABPM-vs.-HBPM out-of-office BP control status. When the 2017 ACC/AHA thresholds were applied as an alternative, the results were essentially the same. CONCLUSIONS: The combined assessment of the office and home BP is useful in clinical practice. Especially for patients whose office BP classification and home BP classification conflict, the complementary clinical use of both HBPM and ABPM might be recommended.

Surface code for low-density qubit array.

Surface code is a promising candidate for the quantum error corrections needed for fault-tolerant quantum computations because it can operate on a two-dimensional grid of qubits. However, the gates and control lines become dense as more and more qubits are integrated, making their design and control difficult. This problem can be alleviated if the surface code can operate on sparse qubit arrays. Here, we give an solution for an array in which qubits are placed on edges as well as on nodes of a two-dimensional grid. The qubits on the edges are divided into two groups: those in one group act as the deputies of data qubits; the others act as deputies of the syndrome qubits. Syndrome outputs are obtained by multiplying the measured values of the syndrome and edge qubits. The procedure for the quantum part is the same as that of the ordinary surface code, making the surface code applicable to sparse qubit arrays.

Associations of office brachial blood pressure, office central blood pressure, and home brachial blood pressure with arterial stiffness.

Accurate blood pressure (BP) measurement is necessary for the evaluation and treatment of hypertension to prevent the progression of subclinical vascular disease, including arterial stiffness. We investigated the associations between brachial-ankle pulse wave velocity (baPWV), a measure of arterial stiffness, and each of office brachial systolic BP (SBP) with and without an observer present (attended or unattended office brachial SBP), attended or unattended office central SBP, and home brachial SBPs (specifically, the means of morning, evening, or morning-evening home brachial SBP) in patients being treated for hypertension. Measurements were performed among 70 adults (mean age, 67.0 ± 9.4 years; women, 51.4%) with a mean attended office brachial SBP of 127.6 ± 14.5 mmHg and mean baPWV of 16.3 ± 2.8 m/s. Univariate analysis showed that higher attended office brachial SBP, morning home brachial SBP, and morning-evening home brachial SBP were each statistically significantly associated with higher baPWV (r = 0.25, P = 0.04; r = 0.37, P = 0.002; and r = 0.32, P = 0.006, respectively). Multiple linear regression analysis with adjustments for traditional cardiovascular risk factors showed that only morning home brachial SBP was statistically significantly associated with baPWV [ß = 0.06, 95% confidence interval (0.01-0.11), P = 0.02). In conclusion, higher morning home brachial SBP - but none of the office-measured SBP values - was associated with arterial stiffness.
