Blood pressue

Hypertension is one of the primary causes of morbidity and premature mortality among the working-age population in India. This study evaluated the burden of hypertension and unmet need for hypertension care among working-age men aged 15-54 years in India using data from the fourth round of the National Family Health Survey (NFHS-4, 2015-16). An individual was recognized as hypertensive if his blood pressure was over 140/90 mmHg or if he was consuming anti-hypertensive medication to lower his blood pressue. The study design was based on the Rule of Halves framework...

Post-cardiac arrest syndrome is a complex and critical issue in resuscitated patients undergone cardiac arrest. Ischemic-reperfusion injury occurs in multiple organs due to the return of spontaneous circulation. Bundle of management practicies are required for post-cardiac arrest care. Early invasive coronary angiography should be considered to identify and treat coronary artery obstructive disease. Vasopressors such as norepinephrine and dobutamine are the first-line treatment for shock. Maintainance of oxyhemoglobin saturation greater than 94% but less than 100% is recommended to avoid fatality...

Sixty-one healthy subjects participated in a laboratory study carried out in a simulated clinical setting. Anticipatory anxiety-state was assessed at the arrival and immediately after, with no brief phase of adaptation, measurements of intraocular pressure, heart rate, systolic and diastolic blood pressure were collected. At the end of the procedure, anxiety-trait was also assessed. Results suggest that high levels of both anxiety-state and anxiety-trait significantly predicted a clinically relevant increase of intraocular pressure...

AIMS: To study the effectiveness of dexmedetomidine 1 μg/kg intravenous in ECT in terms of attenuation of the hyperdynamic response, seizures duration, and sedation. DESIGN: This was a prospective, randomized, double-blinded, crossover study...

This paper presents a practical approach to reconstruct brachial artery pressure (BAP) distally from digital artery pressure (DAP). We hypothesize that continuous BAP can simply be approximated by sum of two halves of the continuous DAP shifted by the time delay. In order to test it, we enrolled 30 healthy volunteers for two experiments. We firstly showed that the pressure wave in the digital artery can be considered twice as much as the forward/backward wave in the finger. A simplified individualized transfer function was then derived so as to estimate BAP from DAP...

The effect of an orthostatic stress on cardiovascular and respiratory complexity was investigated to detect impaired autonomic regulation in patients with vasovagal syncope (VVS). A total of 16 female patients and 12 age-matched healthy female subjects were enrolled in a passive 70° head-up tilt test. Also, 12 age-matched healthy male subjects were enrolled to study gender differences. Analysis was performed dynamically using various short-term (5 min) windows shifted by 1 min as well as by 20 min of orthostatic phase (OP) to evaluate local and global complexity...

BACKGROUND: After traumatic brain injury (TBI), the ability of cerebral vessels to appropriately react to changes in arterial blood pressure (pressure reactivity) is impaired, leaving patients vulnerable to cerebral hypo- or hyperperfusion. Although, the traditional pressure reactivity index (PRx) has demonstrated that impaired pressure reactivity is associated with poor patient outcome, PRx is sometimes erratic and may not be reliable in various clinical circumstances. Here, we introduce a more robust transform-based wavelet pressure reactivity index (wPRx) and compare its performance with the widely used traditional PRx across 3 areas: its stability and reliability in time, its ability to give an optimal cerebral perfusion pressure (CPPopt) recommendation, and its relationship with patient outcome...

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure...

RATIONALE, AIMS AND OBJECTIVES: Cardiac surgery (CS) is facilitated by multiple perioperative guidelines and protocols. Use of a clinical pathway (CP) may facilitate the care of these patients. METHODS: This is a pre-post design study in the ICU of a tertiary referral centre. A CP for CS patients in the ICU was developed by ICU-nurses and enabled them to execute proactively predefined actions in accordance with and within the preset boundaries which were part of a variance report...

BACKGROUND: Considering long-term changes in renal sodium handling and blood pressure in maternal protein-restricted (LP) offspring, we assumed that the development of LP hypertension results from abnormal dorsal root ganglia (DRG) neurokinin expression associated with impaired responsiveness of renal sensory receptors, promoting a reduced urinary excretion of sodium. The present study investigates whether increased blood pressure in protein-restricted offspring would be associated with changes in the DRG cells and in renal pelvic wall expression of NK1R, SP and CGRP when compared to NP offspring...

BACKGROUND: Acute kidney injury (AKI) is common following cardiopulmonary bypass. Fontan completion may result in systemic venous hypertension and low cardiac output, reducing renal perfusion pressure (RPP) and further increasing the risk of AKI. We investigated the incidence and risk factors for post-Fontan AKI. METHODS: Single-center retrospective study of children undergoing Fontan completion from 2005 to 2012. Demographic and hemodynamic variables were assessed for association with AKI...

Patients with type 2 diabetes mellitus (T2DM) exhibit an increased risk of cardiovascular (CV) events. Treatment of these patients with traditional as well as newer glucose-lowering drugs has not demonstrated superiority in CV outcomes compared to placebo, despite effective control of diabetes. However, the recently FDA-approved sodium-glucose cotransporter 2 (SGLT2) inhibitors for the treatment of T2DM have demonstrated promising CV-protecting and blood pressure-lowering effects in addition to their effectiveness in glucose lowering, making them a novel class of drugs for the treatment of T2DM...

High blood pressure is a risk factor for atherosclerosis in adults, but whether the same is true in children and young people is not known. This is important to guide management of high blood pressure in children and young people. We aimed to investigate the association in children and young people between blood pressure and carotid intima-media thickness, a non-invasive marker of atherosclerosis, through a systematic review. Studies were retrieved from MEDLINE and EMBASE. Articles were eligible for inclusion if they included at least one measurement of blood pressure and at least one measurement of ultrasound-derived carotid intima-media thickness, both measured during childhood (0-19 years), and a measure of effect size or correlation between the two measurements...

BACKGROUND: Adverse childhood experiences (ACE) increase the risk to develop major depressive disorder (MDD) and obesity or metabolic syndrome in adulthood. In addition, ACE may be associated with an exaggerated endocrine response to stress, which, in turn, may lead to enhanced food intake resulting in obesity and metabolic problems. METHODS: We systematically examined the stress response and consecutive food intake in 32 women with MDD and ACE as determined by a clinical interview (Early Trauma Inventory), 52 women with MDD without ACE, 22 women with ACE but no current or lifetime MDD and 37 healthy women without either MDD or ACE...

OBJECTIVE: To evaluate the impact of infant growth on childhood health by examining the associations of detailed longitudinal infant weight velocity patterns with childhood cardiovascular and metabolic outcomes. STUDY DESIGN: In a population-based prospective cohort study of 4649 children, we used repeated growth measurements at age 0-3 years to derive peak weight velocity (PWV), age at adiposity peak (AGEAP), and body mass index at adiposity peak (BMIAP). At age 6 years, we measured blood pressure, left ventricular mass, and cholesterol, triglyceride, and insulin concentrations and defined children with clusters of risk factors...

AIM: To estimate the diagnostic and informative value of clinical and laboratory parameters in the development and progression of liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD) to enhance efficiency of their treatment. SUBJECTS AND METHODS: An open-label case-control study included 77 patients with NAFLD. Clinical and laboratory examinations were done. To search for additional noninvasive fibrosis markers, the investigators studied the serum concentrations of insulin, leptin, adiponectin, matrix metalloproteinase-9 (MMP-9) and its inhibitors, such as tissue inhibitor of matrix metalloproteinases 1 (TIMP-1) and TIMP-2...

BACKGROUND: The AGE-RAGE-oxidative stress (AROS) axis is involved in the onset and progression of metabolic syndrome induced by a high-fructose diet (HFD). PPARγ activation is known to modulate metabolic syndrome; however a systems-level investigation looking at the protective effects of PPARγ activation as related to the AROS axis has not been performed. The aim of this work is to simultaneously characterize multiple molecular parameters within the AROS axis, using samples taken from different body fluids and tissues of a rat model of HFD-induced metabolic syndrome, in the presence or absence of a PPARγ agonist, Rosiglitazone (RGZ)...
