[PMID: 36433504 PMCID: PMC9698253 DOI: 10.3390/s22228907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/11/2022] [Accepted: 11/15/2022] [Indexed: 06/16/2023]
Abstract
In this study, a bottom-gated ZnO thin film transistor (TFT) pressure sensor with nanorods (NRs) is suggested. The NRs are formed on a planar channel of the TFT by hydrothermal synthesis for the mediators of pressure amplification. The fabricated devices show enhanced sensitivity by 16~20 times better than that of the thin film structure because NRs have a small pressure transmission area and causes more strain in the underlayered piezoelectric channel material. When making a sensor with a three-terminal structure, the leakage current in stand-by mode and optimal conductance state for pressure sensor is expected to be controlled by the gate voltage. A scanning electron microscope (SEM) was used to identify the nanorods grown by hydrothermal synthesis. X-ray diffraction (XRD) was used to compare ZnO crystallinity according to device structure and process conditions. To investigate the effect of NRs, channel mobility is also extracted experimentally and the lateral flow of current density is analyzed with simulation (COMSOL) showing that when the piezopotential due to polarization is formed vertically in the channel, the effective mobility is degraded.

Botha D, Breet Y, Schutte AE. Comparing the associations of clinic vs. ambulatory blood pressure with subclinical organ damage in young healthy adults: the African-PREDICT study. Hypertens Res 2021; 44:840-849. [PMID: 33564179 DOI: 10.1038/s41440-021-00627-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 12/17/2020] [Accepted: 01/05/2021] [Indexed: 01/20/2023]
Abstract
Raised blood pressure (BP) causes pathophysiological cardiovascular changes resulting in target organ damage. Although ambulatory and central BP relate more strongly to outcomes than clinical brachial BP in the elderly population, it is unknown which measure of BP is most strongly associated with markers of organ damage in younger populations. We compared the strength of associations between different BPs and measures of subclinical organ damage and investigated whether ethnic differences exist between these associations. The design was a cross-sectional analysis of the African-PREDICT study, including young black and white men and women (aged 20-30, N = 1202). We obtained clinic, ambulatory, and central BP readings, as well as measures of subclinical organ damage: central retinal arteriolar equivalent (CRAE) from fundus images, echocardiography to determine left ventricular mass index (LVMi), carotid intima media thickness (CIMT), carotid-femoral pulse wave velocity (PWV), and albumin-to-creatinine ratio (ACR) determined from spot urine samples. Overall, weak correlations were evident between CIMT, ACR, and BP, whereas CRAE, LVMi, and PWV correlated strongly with BP. In the total group, clinic brachial BP had stronger associations with CRAE, LVMi, and PWV (all p < 0.001) than ambulatory and central BP. Although the ethnic groups showed similar correlations between CRAE, LVMi, CIMT, and the various BPs, PWV correlated more strongly with ambulatory systolic BP (p < 0.001) in white participants. In young healthy adults, clinic brachial BP correlated more strongly with measures of early target organ damage than central or ambulatory BP. No differences were observed between correlations of BP and measures of target organ damage in the two ethnic groups.

Abstract
This review portrays how ambulatory blood pressure (BP) monitoring was established and recommended as the method of choice for the assessment of BP and for the rational use of antihypertensive drugs. To establish much-needed diagnostic ambulatory BP thresholds, initial statistical approaches evolved into longitudinal studies of patients and populations, which demonstrated that cardiovascular complications are more closely associated with 24-hour and nighttime BP than with office BP. Studies cross-classifying individuals based on ambulatory and office BP thresholds identified white-coat hypertension, an elevated office BP in the presence of ambulatory normotension as a low-risk condition, whereas its counterpart, masked hypertension, carries a hazard almost as high as ambulatory combined with office hypertension. What clinically matters most is the level of the 24-hour and the nighttime BP, while other BP indexes derived from 24-hour ambulatory BP recordings, on top of the 24-hour and nighttime BP level, add little to risk stratification or hypertension management. Ambulatory BP monitoring is cost-effective. Ambulatory and home BP monitoring are complimentary approaches. Their interchangeability provides great versatility in the clinical implementation of out-of-office BP measurement. We are still waiting for evidence from randomized clinical trials to prove that out-of-office BP monitoring is superior to office BP in adjusting antihypertensive drug treatment and in the prevention of cardiovascular complications. A starting research line, the development of a standardized validation protocol for wearable BP monitoring devices, might facilitate the clinical applicability of ambulatory BP monitoring.

Abstract
INTRODUCTION Based on defining criteria, hypertension (HTN) affects 31% to 46% of the adult U.S. population and almost 20% of service members. Resistant HTN (rHTN) consumes significant resources, carries substantial morbidity and mortality risk and costs over $350 billion dollars annually. For multiple reasons, only 48.3% of people with HTN are controlled, e.g., undiagnosed secondary HTN, therapeutic or diagnostic inertia, and patient adherence. Our purpose was to determine the feasibility of a web-based clinical decision support tool (CDST) using a renin-aldosterone system (RAS) classification matrix and drug sequencing algorithm to assist providers with the diagnosis and management of uncontrolled HTN (rHTN). Outcomes were blood pressure (BP) rates of control, provider management time, and end-user satisfaction. METHODS This two-phase, prospective, non-randomized, single-arm, six-month pilot study was conducted in primary care clinics at a tertiary military medical center. Patients with uncontrolled HTN and primary care providers were recruited. Phase 1 patients checked their BP twice daily (AM and PM), three times weekly using a standardized arm cuff. Patients with rHTN were enrolled in phase 2. Phase 2 patients were managed virtually by providers using the CDST, the RAS classification matrix, and the drug sequencing algorithm which incorporated age, ethnicity, comorbidities, and renin/aldosterone levels. Medications were adjusted every 10 days until BP was at target, using virtual visits. RESULTS In total, 54 patients and 16 providers were consented. One transplant patient was disqualified, 29 met phase 2 criteria for rHTN, and 6 providers completed the study. In phase 1, 45% (n = 24) of patients were identified as having apparent uncontrolled HTN using peak diurnal blood pressure (pdBP) home readings. In phase 2 (n = 29), previously undetected RAS abnormalities were identified in 69% (n = 20) of patients. Blood pressure control rates improved from 0% to 23%, 47%, and 58% at 2, 4, and 6 months, respectively. Provider management time was reduced by 17%. Using home pdBP readings identified masked HTN in almost 20% of patients that would have been missed by a single daily AM or PM home BP measurement. Feasibility and satisfaction trends were favorable. CONCLUSIONS Despite significant morbidity, mortality, and existing guidelines, over half of hypertensive patients are uncontrolled. Our results suggest that this CDST used with pdBP monitoring is a feasible option to facilitate improved rates of control in rHTN, aid in overcoming therapeutic/diagnostic inertia, improve identification of secondary HTN, and potentially, access. Further research with this tool in a larger population is recommended.

Abstract
Objective To compare agreement and reliability between clinician-measured and patient self-measured clinical and functional assessments for use in remote monitoring, in a home-based setting, using telehealth. Design Reliability study: repeated-measure, within-subject design. Setting Trained clinicians measured standard clinical and functional parameters at a face-to-face clinic appointment. Participants were instructed on how to perform the measures at home and to repeat self-assessments within 1 week. Participants Liver transplant recipients (LTRs) (N=18) (52±14y, 56% men, 5.4±4.3y posttransplant] completed the home self-assessments. Interventions Not applicable. Main Outcome Measures The outcomes assessed were body weight, systolic and diastolic blood pressure (SBP and DBP), waist circumference, repeated chair sit-to-stand (STST), maximal push-ups, and the 6-minute walk test (6MWT). Intertester reliability and agreement between face-to-face clinician and self-reported home-based participant measures were determined by intraclass-correlation coefficients (ICCs) and Bland-Altman plots, which were compared with minimal clinically important differences (MCID) (determined a priori). Results The mean difference (95% confidence interval) and [limits of agreement] for measures (where positive values indicate lower participant value) were weight, 0.7 (0.01-1.4) kg [−2.2 to 3.6kg]; waist 0.4 (−1.2 to 2.0) cm [−5.9 to 6.8cm]; SBP 7.7 (0.6-14.7 ) mmHg [−19.4 to 34.9mmHg]; DBP 2.4 (−1.4 to 6.2 ) mmHg [−12.2 to 17.0mmHg]; 6MWT, 7.5 (−29.1 to 44.1) m [−127.3 to 142.4m]; STST 0.5 (−0.8 to 1.7) seconds [−4.3 to 5.3s]; maximal push-ups −2.2 (−4.4 to −0.1) [−10.5 to 6.0]. ICCs were all >0.75 except for STST (ICC=0.73). Mean differences indicated good agreement than MCIDs; however, wide limits of agreement indicated large individual variability in agreement. Conclusions Overall, LTRs can reliably self-assess clinical and functional measures at home. However, there was wide individual variability in accuracy and agreement, with no functional assessment being performed within acceptable limits relative to MCIDs >80% of the time.

Abstract
Wearable technologies will play an important role in advancing precision medicine by enabling measurement of clinically-relevant parameters describing an individual's health state. The lifestyle and fitness markets have provided the driving force for the development of a broad range of wearable technologies that can be adapted for use in healthcare. Here we review existing technologies currently used for measurement of the four primary vital signs: temperature, heart rate, respiration rate, and blood pressure, along with physical activity, sweat, and emotion. We review the relevant physiology that defines the measurement needs and evaluate the different methods of signal transduction and measurement modalities for the use of wearables in healthcare.

Abstract
The present paper reports differences between office blood pressure (BP) measurement (OBPM) and ambulatory blood pressure measurement (ABPM) in a large multi-centre Indian all comers' population visiting primary care physicians. ABPM and OBPM data from 27,472 subjects (aged 51 ± 14 years, males 68.2%, treated 45.5%) were analysed and compared. Patients were classified based on the following hypertension thresholds: systolic BP (SBP) ≥ 140 and/or diastolic BP (DBP) ≥90 mmHg for OBPM, and SBP ≥ 130 and/or DBP ≥ 80 mmHg for 24-h ABPM, and SBP ≥ 120 and/or DBP ≥ 70 mmHg for night-time ABPM and SBP ≥ 135 and/or DBP ≥ 85 mmHg for daytime ABPM, all together. White coat hypertension (WCH) was seen in 12.0% (n = 3304), masked hypertension (MH) in 19.3% (n = 5293) and 55.5% (n = 15,246) had sustained hypertension. Isolated night-time hypertension (INH) was diagnosed in 11.9% (n = 3256). Untreated subjects had MH relatively more often than treated subjects (23.0% vs. 14.8%, p < 0.0001; respectively). Females had higher relative risk (RR) of having WCH than males (RR 1.16 [CI 95, 1.07-1.25], p < 0.0001). Whereas, males had higher RR of MH than females (RR 1.09 [CI 95, 1.02-1.17] p < 0.01). INH subjects had lower average systolic and diastolic dipping percentages (0.7 ± 6.6/ 2.2 ± 7.9 vs. 9.0 ± 7.3/11.9 ± 8.5, p < 0.001) than those without INH. In conclusion, for diagnosis of hypertension there was a contradiction between OBPM and ABPM in approximately one-third of all patients, and a substantial number of patients had INH. Using ABPM in routine hypertension management can lead to a reduction in burden and associated costs for Indian healthcare.

Abstract
Background Home blood pressure (BP) and unattended automated BP (uAOBP) monitoring have been recommended by guidelines for the care of hypertensive subjects. However, BP measurements in the peripheral arteries cannot serve as direct substitutes for their central counterparts. Moreover, the comparative effectiveness and safety of BP-guided strategies using these BP measuring devices have never been evaluated. Methods/design Patients with uncontrolled or newly diagnosed hypertension aged 20–90 years will be recruited via outpatient clinics and allocated into three arms by stratified randomization (baseline systolic BP 130–155 mmHg and 155–180 mmHg): home BP, uAOBP, and central BP-guided treatment. At each scheduled visit to the clinic, a patient’s BP will be measured by each of the three methods of measuring BP. The blood pressure from three different methods will be confirmed available at each visit. Patients and physicians will be blinded to the allocated interventions because they will use measured BP values in the clinic through a standardized report format. A common BP target for systolic blood pressure (SBP) of 130 mmHg is adopted for these BP-guided strategies. The primary outcome is the change of 24-h mean ambulatory SBP at 3 months. A key secondary outcome is to determine the percentage achieving their target BPs at 3 months and the decrease of left ventricular mass at 12 months. Discussion To our knowledge, this is the first prospective double-blind randomized controlled trial to assess the optimal guiding strategy for hypertension. It will help to define which BP monitoring method is the most effective for guiding the clinical management of hypertension. It will provide good evidence to support future guideline recommendations for BP monitoring devices. Trial registration ClinicalTrials.gov, NCT03578848. Registered on 4 June 2018.

Abstract
In the proposed work, we report on qualitative as well as quantitative biospeckle monitoring of functional blood flow on the human hand. Intensity-based algorithms namely generalized difference and our earlier proposed algorithm parameterized global-average Fujii have been approached for the first time to analyze various physiological changes due to effect of different treatments such as hot and cold water treatments on the palm which can be helpful in examining cardiovascular and related diseases. In addition, blood flow has been monitored for the first time on face scrub, beauty creams, and pain relief ointments applied over the back of the palm. It has been found that, on application of four beauty creams namely Fair & Lovely, Ponds White Beauty, Vicco Turmeric, and Lotus Herbals Safe Sun on the back of the palm, blood flow increases and becomes highest (mean activity, 154.87) for Fair & Lovely among the four beauty creams. In addition, pain relief ointments such as Volini, Fast Relief, Molid Gel, and Zandu Gel increase blood flow after their applications on the back of the palm and Volini gives maximum increase of average blood flow (31.59) and hence can be considered one of the best among the four ointments. It has been further concluded that the person having more hemoglobin (14) and higher blood pressure (120/90) may have more blood flow or mean activity (85.80). In addition, it has been also concluded that although hot and cold water treatments can be used for increment in blood flow, temperature should be retained according to need and sensitivity of the sample.

Abstract
Although there has been an observed progress in the treatment of hypertension, its prevalence remains elevated and constitutes a leading cause of cardiovascular disease development. Resistant hypertension is a challenge for clinicians, as the available treatment options have reduced success. Physical activity and exercise training play an important role in the management of blood pressure. The importance of physical activity and exercise training as part of a comprehensive lifestyle intervention is acknowledged by several professional organizations in their recommendations/guidelines for the management of arterial hypertension. Aerobic exercise, dynamic resistance exercise, and concurrent training - the combination of dynamic resistance and aerobic exercise training in the same exercise session or on separate days - has been demonstrated to reduce blood pressure and help in the management of hypertension. The present review draws attention to the importance of exercise training in the management of blood pressure in both hypertension and resistant hypertension individuals.

Abstract
OBJECTIVE Elevated blood pressure is a significant public health concern, particularly given its association with cardiovascular disease risk, including stroke. Caring for a loved one with Alzheimer disease has been associated with physical health morbidity, including higher blood pressure. Engagement in adaptive coping strategies may help prevent blood pressure elevation in this population. This 5-year longitudinal study examined whether greater participation in pleasant leisure activities was associated with reduced blood pressure in caregivers. METHODS Participants were 126 in-home spousal Alzheimer's caregivers (M [SD] age = 74.2 [7.9] years) that completed five yearly assessments. Linear mixed-effects models analysis was used to examine the longitudinal relationship between pleasant leisure activities and caregivers' blood pressure, after adjusting for demographic and health characteristics. RESULTS Greater engagement in pleasant leisure activities was associated with reduced mean arterial blood pressure (B = -0.08, SE = 0.04, p = .040). Follow-up analyses indicated that engagement in activities was significantly associated with reduced diastolic (B = -0.07, SE = 0.03, p = .030) but not systolic blood pressure (B = -0.10, SE = 0.06, p = .114). In addition, mean arterial blood pressure was significantly reduced when caregiving duties ended because of placement of care recipients in nursing homes (B = -3.10, SE = 1.11, p = .005) or death of the care recipient (B = -2.64, SE = 1.14, p = .021). CONCLUSIONS Greater engagement in pleasant leisure activities was associated with lowered caregivers' blood pressure over time. Participation in pleasant leisure activities may have cardiovascular health benefits for Alzheimer's caregivers.
