ABSTRACT

Although the effect of face masks on preventing airborne transmission of SARS-CoV-2 is well studied, no study has evaluated their effect on blood pressure (BP). Therefore, we investigated the effect of surgical masks on BP in 265 treated hypertensive patients. Following the routine mask-on office BP measurement, patients were left alone and randomized to automated office BP measurement, with measurements taken after first wearing a mask for 10 min, then without wearing the mask for 10 min, and vice versa. Among the participants, 115 were women (43.4%), the mean age was 62 +/- 12 years, and the mean office BP was 134 +/- 15/81 +/- 12 mmHg. There was no significant difference between mask-on unattended systolic BP (133 +/- 15 mmHg) and mask-off unattended systolic BP (132 +/- 15 mmHg) (P = 0.13) or between mask-on unattended diastolic BP (77 +/- 13 mmHg) and mask-off unattended diastolic BP (76 +/- 13 mmHg) (P = 0.32). Surgical masks had no effect on BP in treated hypertensive patients.Copyright © 2022 Krause und Pachernegg GmbH. All rights reserved.

ABSTRACT

Aims: May Measurement Month (MMM) is a global campaign to enhance hypertension awareness by intensive blood pressure measuring campaign during a month period of May. May Measurement Month 2020 was not officially executed globally, especially in light of COVID-19 pandemic. But in Korea, the MMM committee decided to carry on with self-initiated project to succeed MMM started in 2019 in Korea. And we adopted new online strategies for those with age of 18 or older under the MMM. Methods and results: Korea 2020 theme in Korean of 'Look for the Young Hypertension'. A promotional video, a subtitled translated global promotional video, and four educational contents were uploaded on Youtube®. Seven online posters or card news were uploaded on main blog. And 71 articles by 60 websites from 10 medical media company were published. The MMM keyword exposure in Naver® portal Search Advertisements was 2500 searches per day. There were 3519 visits to the MMM blog, and 114 people participated in snapshot challenges. Four social network service channels were activated, and there was an increase in Facebook and Instagram followers of 6.5- and 5.8-fold, respectively. GoodDoc® application programming interface messages were sent 97876 times (2589 responses). For a user created contents contest, 28 competitors, mostly young, participated. Conclusion: Even during the COVID-19 pandemic, the MMM campaign was able to survive using a 'new normal' online format. The shift to on-line activity during the pandemic will contribute to a breakthrough MMM campaign in the future that can be combined with off-line protocols even after the pandemic.

ABSTRACT

Hypertension is the most important risk factor for global disease burden. Detection and management of hypertension are considered as key issues for individual and public health, as adequate control of blood pressure levels markedly reduces morbidity and mortality associated with hypertension. Aims of these practice guidelines for the management of arterial hypertension of the Spanish Society of Hypertension include offering simplified schemes for diagnosis and treatment for daily practice, and strategies for public health promotion. The Spanish Society of Hypertension assumes the 2018 European guidelines for management of arterial hypertension developed by the European Society of Cardiology and the European Society of Hypertension, although relevant aspects of the 2017 American College of Cardiology/American Heart Association guidelines and the 2020 International Society of Hypertension guidelines are also commented. Hypertension is defined as a persistent elevation in office systolic blood pressure ≥ 140 and/or diastolic blood pressure ≥ 90 mmHg, and assessment of out-of-office blood pressure and global cardiovascular risk are considered of key importance for evaluation and management of hypertensive patients. The target for treated blood pressure should be < 130/80 for most patients. The treatment of hypertension involves lifestyle interventions and drug therapy. Most people with hypertension need more than one antihypertensive drug for adequate control, so initial therapy with two drugs, and single pill combinations are recommended for a wide majority of hypertensive patients.

ABSTRACT

Background: A non-immediate hypertensive response short after COVID- 19 vaccination has been reported. Mild to moderate elevated arterial blood pressure (BP) levels have been documented few days after a single or two-doses vaccine. This study sought to investigate this observation as a potential side effect in patients with known hypertension and healthy controls. Method(s): A total of 100 vaccinated patients between the age of 50 to 70 years old were studied. They were randomly assigned to one of the approved and available vaccines (Pfizer, Astra Zeneca, Moderna, Johnson & Johnson). Half of them were hypertensives under medical treatment and half of them were not. All participants had systolic BP <140mmHg and diastolic BP <90mmHg before vaccination and volunteered for standard daily home BP measurements (HBPM) and ambulatory BP measurements (ABPM) between the 1st and the 21st day after considered fully COVID-19 vaccinated. Result(s): All patients, hypertensives or not, had at some point a recorded hypertensive response for both systolic (SBP) and diastolic (DBP) BP after considered fully vaccinated. Hypertensives were older and with higher body mass index (BMI). Some of the hypertensive patients received additional medication whereas some of the non-hypertensive patients started life modification changes and systematic BP measurements for a possible diagnosis of hypertension. Conclusion(s): Vaccination for COVID-19 seems to be related with a short period of hypertensive response. This phenomenon was partial and mostly observed in older overweight hypertensives.

ABSTRACT

Studies about headaches associated with acute ischemic stroke in patients suffering from migraine were limited, and therefore we present a clinical case of central post-stroke pain (CPSP) in a 47-year-old woman with migraine and lacunar infarcts in the medulla oblongata and also possible mechanisms of CPSP in patients with migraine. Magnetic resonance imaging of the brain revealed lacunar infarction in the medulla oblongata on the right (vertebral artery basin) and a single focus of gliosis in the parietal lobe on the right. Magnetic resonance angiography of cerebral vessels showed the fetal type of structure of both posterior cerebral arteries. This clinical case is a complex clinical situation of a combination of secondary headaches (post-stroke) in a patient with a primary headache (migraine), which was successfully treated by the combined administration of first-line drugs for the treatment of neuropathic pain in a patient with lacunar infarcts in the medulla oblongata. The treatment of CPSP is a difficult task due to the insufficiently unexplored mechanisms of development, the most effective approaches are those aimed at reducing the increased excitability of neurons.Copyright © 2023, Indian Association of Biomedical Scientists.

ABSTRACT

Objective. To study the changes in the vascular wall, vascular age and metabolic parameters in polymorbid COVID-19 conva-lescents. Material and methods. The study included 62 patients with hypertension who reached the target blood pressure (BP) with dual an-tihypertensive therapy after severe and extremely severe COVID-19. The following examinations were performed: laboratory tests of metabolic parameters, assessment of changes in the vessel elasticity indices (pulse-wave velocity (PWV), augmentation index (AI), central systolic BP (cSBP), 24-hour BP monitoring, and non-invasive markers of liver fibrosis. Results. According to office BP measurements, after the coronavirus infection, an increase in systolic BP (SBP) by 29.6% and di-astolic BP (DBP) by 23.6%, as well as heart rate (HR) by 11.8% (p<0.05) was reported during regular antihypertensive therapy. In addition, 24-hour BP monitoring data indicated an increase in the average daily SBP, DBP, and heart rate. After the coronavirus infection, an increase in PWV by 35.4% (p<0.05), AI by 24.4% (p<0.05), cSBP by 22.1% were reported. Carbohydrate and lipid metabolism parameters deteriorated. A pronounced adverse effect of coronavirus infection on liver function was observed. The vascular age (according to the modified SCORE scale) increased by 6 years (p<0.05). Conclusion. Our study showed that patients after severe and extremely severe COVID-19 have a high risk of liver fibrosis, hypertension and lipid metabolism control worsening and accelerating vascular aging.Copyright © 2023, Media Sphera Publishing Group.

ABSTRACT

Aim: This study aimed at investigating the impact of COVID-19 lockdown on metabolic profile in bipolar disorder and schizophrenia patients at the time of COVID-19. Material(s) and Method(s): This study was completed with 190 individuals diagnosed with schizophrenia (116) and bipolar disorder (74). Waist circumference and blood pressure measurements were taken on the same date as triglyceride, glucose and HDL data in the electronic recording system of the participants. Initial assessment data are measurements within 3 months prior to the publication of the first case in Turkey. The second evaluation data, on the other hand, is the data obtained within 3 months after the date of removal or relaxation of the restrictions, which is defined as the normalization period. Result(s): A significant increase was observed in the incidence of metabolic syndrome in the participants after the COVID-19 lockdown. In addition, a significant increase in glucose, triglyceride and diastolic blood pressure values, and a significant decrease in HDL values were detected. There was no significant change in systolic blood pressure and waist circumference values. Discussion(s): It has been shown that the COVID-19 lockdown increases the incidence of metabolic syndrome in patients with schizophrenia and bipolar disorder and causes irregularities in metabolic syndrome parameters.Copyright © 2022, Derman Medical Publishing.

ABSTRACT

Background: Hypertension is the most important modifiable cause of cardiovascular (CV) disease and all-cause mortality worldwide. Numerous epidemiological studies and pharmacological intervention trials have demonstrated that lower and lowering blood pressures (BP) are associated with fewer CV events and lower mortality. Despite the positive correlations between BP levels and later CV events are continuous since BP levels as low as 90/60 mmHg in almost all large-scale epidemiological studies, the diagnostic criteria of hypertension and BP thresholds and targets of antihypertensive therapy have largely remained at the level of 140/90 mmHg in the past 30 years (since the release of the Fifth Report of the Joint National Committee [JNC 5] on high BP in 1993). The publication of both the SPRINT and the STEP trials (comprising >8,500 Caucasian/African and Chinese participants, respectively) provides enough evidence to shake this 140/90 mmHg dogma. In both trials, lowering systolic BP (SBP) to <130 mmHg, compared to the traditional SBP target of <140 (130-139) mmHg, was consistently associated with a 25-30% relative risk reduction in CV events. Another dogma regarding hypertension management is "office (or clinic) BP measurements" Although standardized office BP measurement has been widely recommended, the practice of office BP measurements is hard to be or has never been ideal in real-world practice. Further, the debate regarding the numerical equivalence between automated office BP (AOBP) measurements adopted in the SPRINT trial and office BP measurements has never been settled. The variations of office BP readings and the differences between office BP and home BP readings bewilder not only patients, but also healthcare professionals. On the other hand, out-of-office BP monitoring receives growing attention in contemporary hypertension guidelines. Home BP monitoring (HBPM) and ambulatory BP monitoring (ABPM) are two recognized approaches to obtaining out-of-office BP. HBPM is easy-to-use, more likely to be free of environmental and/or emotional stress (such as white-coat effect), feasible to document long-term BP variations, of good reproducibility and reliability, and more correlated with hypertension-mediated organ damage (HMOD) and CV events. Methods/Results: The Taiwan Hypertension Society (THS) and the Taiwan Society of Cardiology (TSOC) jointly issued the Consensus Statement on HBPM in 2020. The "722" protocol to standardize HBPM has been advocated by both Societies and widely accepted by healthcare professionals. In the 2022 Taiwan Hypertension Guidelines, we break the dogma of "office BP-based management strategy" and further expand the role of HBPM to the whole hypertension management process, from diagnosis to long-term follow-up. The Task Force considers that, to improve the quality of long-term management of all chronic diseases including hypertension, patients themselves should take an active role and HBPM is the right tool to achieve this goal, regardless of many other advantages of HBPM. This approach is of particularly importance in the post-COVID era and can bridge the management with artificial intelligence technologies. Conclusion(s): To facilitate implementation of the guidelines, a series of flowcharts to encompass assessment, adjustment, and HBPM-guided hypertension management are provided.

ABSTRACT

Background Primary care electronic medical records (EMRs) data can be used to inform health services, disease surveillance, and interventions. However, its utility is reliant on how well variables are captured. The COVID-19 pandemic shifted primary care delivery to virtual care resulting in fewer patients having their blood pressure (BP) checked in office. As such, BP may not be well documented in the structured fields of the EMR. In the EMR, BP's are used to identify patients who have hypertension, assess rates of hypertension screening, and evaluate hypertension management. The purpose of this study was to determine the change in BP documentation during the COVID-19 pandemic. Methods Data for this study were from the University of Toronto Practice-Based Research Network (UTOPIAN) Data Safe Haven, a EMR database which contains clinical records from family medicine clinics in Ontario, Canada. Hypertension visits (ICD-9 billing code 401) were assessed pre-pandemic (Jan 2017-Dec 2019) and during the pandemic (Jan 2020-Dec 2021) for structured BP. A sample of 12% of hypertension visits during the pandemic without structured BP measures were reviewed to determine if BP was recorded in an unstructured format. Two abstractors reviewed progress notes of patient charts to identify if BP was recorded. Results were analyzed using descriptive statistics. Results Pre-pandemic, 67% of hypertension visits had a BP recorded in structured fields (OR=4.14, 95% CI: 4.04-4.23), however this significantly decreased during the pandemic with only 33% of cases having a recorded BP (OR=0.24, 95% CI: 0.23-0.24). In the pandemic, 55% of hypertension visits were virtual. In the pandemic, 10% of virtual visits (OR=0.01, 95% CI: 0.01-0.01), versus 59% of in-person visits did have a structured BP (OR=2.48, CI: 2.37-2.60). Abstractors reviewed 3200 hypertension visits without structured BP. 55% of hypertension visits had a BP recorded in the unstructured progress notes. Conclusion There are clear gaps in pandemic BP recordings most likely due to high rates of virtual visits. Given that virtual visits will continue, future research should develop strategies for capturing BP from progress notes in EMR databases.Copyright © 2023 American College of Cardiology Foundation

ABSTRACT

Blood pressure (BP) is generally regarded as the vital sign most strongly correlated with human health. However, for decades, BP measurement has involved a cuff, which causes discomfort and even carries a risk of infection, given the current prevalence of COVID-19. Some studies address these problems using remote photoplethysmography (rPPG), which has shown great success in heart rate detection. Nevertheless, these approaches are not robust, and few have been evaluated with a sufficiently large dataset. We propose an rPPG-based BP estimation algorithm that predicts BP by leveraging the Windkessel model and hand-crafted waveform characteristics. A waveform processing procedure is presented for the rPPG signals to obtain a robust waveform template and thus extract BP-related features. Redundant and unstable features are eliminated via Monte Carlo simulation and according to their relationship with latent parameters (LSs) in the Windkessel model. For a comprehensive evaluation, the Chiao Tung BP (CTBP) dataset was constructed. The experiment was conducted over a four-week period of time to evaluate the validity period of the personalization in our system. On all the data, the proposed method outperforms the benchmark algorithms and yields mean absolute errors (MAEs) of 6.48 and 5.06 mmHg for systolic BP (SBP) and diastolic BP (DBP), respectively. The performance achieves a 'B' grade according to the validation protocol from the British Hypertension Society (BHS) for both SBP and DBP. © 1963-2012 IEEE.

ABSTRACT

Objective: Main issues in the treatment of hypertension are the low level of blood pressure (BP) control and the economic burden for health care systems. Mobile application with telemonitoring of BP could contribute to better control and lower costs by reducing office visits. This could be useful nowadays with difficult access to health system due to covid-19. The purpose of this study was to investigate if an innovative management strategy of hypertension, such as the use of ESH care application for smartphones combined with a dedicated platform, could improve hypertension control and replace frequent office visits. Design and method: 30 uncontrolled hypertensive patients, treated or untreated [mean age 53 ± 9 years, mean office BP (OBP) 146.3 ± 6.2 / 92.5 ± 9 mmHg, 53% men, 33% smokers, 23% with hypercholesterolemia] were randomized to the application assisted strategy (AAS) (17 patients), where a mobile phone application was offered to communicate home BP measurements (HBPm), or to regular office visits (13 patients). Patients BP measurements (HBPm for AAS and OBP for standard care group) were evaluated in 1 and 3 months with treatment titration if uncontrolled. In all patients OBP and ambulatory BP measurement (ABPM) were evaluated in 6 months. Results: In both groups the reduction in OBP and ABPM was significant in 6 months. In the AAS group the reduction in systolic/diastolic OBP and 24 h systolic/ diastolic BP in 6 months was -26.5 ± 5.6 / -19.4 ± 8.2 mmHg (p < 0,001) and -19.6 ± 7.7 / -13.8 ± 4.8 mmHg (p < 0.001), respectively. In the standard care group, the reduction in systolic/diastolic OBP and 24 h systolic/diastolic BP in 6 months was -22.6 ± 9.7 / -9.6 ± 11 mmHg (p < 0.005) and -18.4 ± 6.0 / - 8.8 ± 4.4 mmHg (p < 0.001). In AAS group compared to standard care group there was a greater reduction in 24 h diastolic BP (-13.8 ± 4.8 mmHg vs -8.8 ± 4.4 mmHg, p = 0.016) and in diastolic OBP (-19.4 ± 8.2 mmHg vs -9.6 ± 11.0 mmHg, p = 0.04). Conclusions: The present results indicate that the monitoring of patients through a mobile health tool could be useful in hypertension management as it is correlated with better BP control compared to office visits. The trial is still enrolling patients.

ABSTRACT

Objective: While there are several studies that have focused on the role of face masks in preventing airborne transmission of SARS-CoV-2, few data are available on their effects on physiological measures, and no study has examined their effects on blood pressure (BP). The purpose of our study was to investigate the effect of surgical masks on BP in drug-treated hypertensive patients who had a routine follow-up visit to a university hospital outpatient hypertension clinic. Design and method: The study included already treated hypertensive patients aged > 18 years, while the exclusion criteria were atrial fibrillation or any other arrhythmia affecting the BP measurement, an arm circumference > 42 cm, mental disorders, Parkinson disease, pregnancy, intolerance to the BP measurement method, or unwillingness to participate. A new surgical mask was provided to all participants to replace the face mask that was already in use. After the routine mask-on office BP measurement, patients were left alone and randomized to automated office BP measurement, with measurements taken after first wearing a mask for 10 min, then without wearing the mask for 10 min, and vice versa. Results: A total number of 265 patients were included in the study. Among the participants, 115 were women (43.4%), the mean age was 62 ± 12 years, and the mean office BP was 134 ± 15 / 81 ± 12 mmHg. There was no significant difference between mask-on unattended systolic BP (133 ± 15 mmHg) and mask-off unattended systolic BP (132 ± 15 mmHg) (P = 0.13) or between mask-on unattended diastolic BP (77 ± 13 mmHg) and mask-off unattended diastolic BP (76 ± 13 mmHg) (P = 0.32). Moreover, there was no difference in the heart rate (mask-on first, 69 ± 11 bpm;mask-off first, 69 ± 11 bpm, P = 0.7). Conclusions: Common surgical masks do not affect systolic/diastolic BP levels during unattended BP measurements in treated hypertensive patients.

ABSTRACT

Introduction: The COVID-19 pandemic has influenced healthcare systems, particularly in the areas of non-communicable diseases, such as hypertension, where the majority of patients require medication therapy and frequent visits. The postal medicine delivery (PMD) approach was an innovative solution to keep antihypertensive drugs accessible under the social distance regulation. Objective: We aimed to investigate the effectiveness of the PMD in terms of blood pressure (BP) control (< 140/90 mmHg), and target organ damage (TOD) including myocardial infarction, heart failure, acute stroke, and progression of chronic kidney disease) during the use of PMD. Design and method: This was a cross-sectional study in a university hospital, conducted between 11th March to 27th May 2020 when the hospital policy stated that outpatient departments' service would be reduced, and physicians were encouraged to use PMD. Patients without a history of TOD and who had a history of well BP control (< 140/90 mmHg) for the last 2 weeks, were enrolled. All of the patients used smartphones and LINE® applications for contacting the nurse coordinator every 3 months to report their home BP. After 6 months of PMD, patients were assigned to have a follow-up visit at the hospital for office BP measurement and having metabolic panel checked. Results: Thirty-eight patients met the inclusion criteria, and 68% were women. Most of the patients (97.4%) had used home BP monitoring (HPBM). The rate of BP control in goal was 64.2%. There was no TOD during the PMD approach. The medication boxes were sent successfully via postal service within 5-10 days, with no loss or damage recorded. All of the patients reported that they had been taking their antihypertensive medications. More than two-thirds (68.4%) continued to follow a low-sodium diet, while 76.3 percent continued to exercise regularly. Conclusions: In the COVID-19 epidemic, the PMD method could be another effective and safe strategy to enhance medicine access, if suitable enrolment criteria and communication between healthcare practitioners and patients are maintained.

ABSTRACT

Introduction: The bispectral index monitors the unawareness component of balanced anaesthesia and gives us the depth of Anesthesia.It reflects the response of the brain to a variety of hypnotic and inhaled anaesthesia agents. The aim of this study was to see the effect of different MAC values of isoflurane on the bispectral index and hemodynamic variations at different MAC values. Material(s) and Method(s): This prospective study was conducted on 20 patients at tertiary care center for 6 months. After induction of Anesthesia, following parameters were recorded: noninvasive blood pressure measurement, heart rate, oxygen saturation, ETCo2 and BIS values. The BIS was continuously monitored and when the MAC values of isoflurane were 0.5, 0.7, 1, 1.2 and 1.5 corresponding BIS values and all the other haemodynamic parameters were noted. Result(s): In 11 patients out of 20 patients satisfactory BIS of 40-60 was achieved at MAC 0.5. In 16 out of 20 patients satisfactory BIS 40-60 was achieved at 0.7 MAC. In all the 20 patients satisfactory BIS was achieved at 1 MAC.In 2 out of 20 patients we couldn't proceed beyond 1.0 MAC because of the fall in MAP to <65mm of Hg. In 4 out of 20 patients we couldn't proceed beyond 1.2MAC because of the fall in MAP to <65mm of Hg. Conclusion(s): Isoflurane produced satisfactory BIS of 40-60 in 16 patients at 0.7 MAC and in all the 20 patients at 1 MAC.Use of BIS in our study helped in better titration of Isoflurane according to patient's individual needs thereby we avoided light plane of anaesthesia or deep hypnosis and the adverse effects associated with it.

ABSTRACT

Introduction: Underserved populations are 40% more likely to have hypertension and three times more likely to die from heart diseases due to uncontrolled blood pressure (BP). Disrupted access to care from the COVID-19 pandemic further puts these populations at higher risks of complications. A C-RPM for hypertension was established in response to this threat. Research Question or Hypothesis: Will C-RPM promote timely BP control among underserved patients during the COVID19 pandemic? Study Design: A retrospective, single-arm observational study conducted in two federally qualified health center sites. Method(s): All adult patients with uncontrolled BP (>=140/90) who received physician or nurse practitioner referral to participate in CRPM were included. Patients who failed to use BP device independently were excluded. All participants received a BP device that transmitted their BP measurements to the institution electronic health records. Clinical pharmacists, under a collaborative practice agreement, followed the readings and provided dose adjustments via telemedicine. Patient demographics were collected at baseline and BP readings were tracked daily for the first three months. Descriptive analysis, ASCVD risk calculator and paired t-test were used accordingly. Result(s): Between August and December 2021, 89 patients were referred, of which 70 (78.7%) monitored BP daily while 19 (21.3%) were lost to follow up.
