Filter by:Energy drinks consumption has varied effects on the hemodynamic, blood glucose levels, brain functions and memory. The use of energy drinks is pervasive and especially young adults consume it often as binge drinking. The negative health effects of excessive use of energy drinks has been reported in the scientific literature. Often energy drinks are consumed to enhance alertness and cognition improvement. In this trial, the investigators intend to compare the effects of a widely available energy drink brand in the country with the usual black tea with 5gm sugar and milk. The aims of this study is: 1. To determine the effect of consumption of energy drinks on hemodynamics parameters. 2. To determine the effect of consumption of energy drinks on short term memory 3. To determine the effect of consumption of energy drinks on vigilance in adults 4. To determine the effect of consumption of energy drinks on blood glucose in adults 5. To analyze the effect of energy drink on perception in adults
Type 2 diabetes mellitus (T2D) is a chronic inflammatory disease that is associated with loss of functional capacity and increased blood pressure. Coupled with this, there is an increased risk of falls and fractures in patients with T2D. On the other hand, conventional training programs for resistance, aerobic or combined exercises are strongly recommended for people with T2D, as they promote a reduction in the glycemic rate and blood pressure, and an improvement in functional capacity. However, little is known about unconventional training programs such as PILATES (dynamic and isometric muscle actions) on functional capacity and cardiovascular adaptations in T2D.
Approximately 12% of the world's population have a have a common C677T polymorphism in the gene encoding the folate metabolising enzyme, methylenetetrahydrofolate reductase (MTHFR). Homozygosity for the polymorphism (TT genotype) appears to result in an increased requirement for the B-vitamins folic acid and riboflavin and more importantly results in an increased risk of developing high blood pressure (BP). Previous work from our Centre has demonstrated significantly higher BP in those with the TT genotype. This work has been conducted in cohorts with premature cardiovascular disease (CVD) and hypertension without overt CVD, but the effect in younger, healthier individuals is unexplored. To date our studies have also focused on BP as the primary outcome, but newer markers of vascular health including central pressure and hemodynamics have emerged as superior prognostic indicators of CVD. The effect of the TT genotype on these measures is thus an important area for investigation and may help us understand the mechanism linking the genotype with BP, which is currently unknown. As adults with the TT genotype appear to have increased requirements for riboflavin and folic acid, and BP in TT adults appears to be riboflavin dependent, the influence of these vitamins on central measures is an area for consideration. Study Design This is an observational study investigating the blood pressure profiles of healthy adults aged 18-65 years, stratified by MTHFR genotype. Apparently healthy adults will be recruited from workplaces and the general community across Northern Ireland and screened for the polymorphism via buccal swab. Those with the TT genotype and a similar number of non-TT (i.e. CC/CT) genotype individuals will be contacted and asked to come to attend a one-off appointment. Brachial BP will be assessed by an electronic BP monitor, central BP and central haemodynamics (augmentation index, augmentation pressure and pulse wave velocity) will be assessed by SphygmoCor XCEL. In addition, anthropometric measurements, health and lifestyle information and a blood sample will be obtained. Data will be statistically analysed using SPSS software to if determine differences between gentoype groups exist.
The purpose of this study is to evaluate the accuracy of the YuWell YE660D oscillometric upper-arm blood pressure monitor for clinic and home in general population according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2:2018).
The investigators propose a pilot trial to (1) proof the concept that defining the intraoperative mean arterial pressure (MAP) intervention threshold based on the mean nighttime MAP (assessed using preoperative automated blood pressure monitoring) results in clinically relevant (mean nighttime MAP ± 10 mmHg) different target values compared with using an absolute population-derived MAP intervention threshold of 65 mmHg (primary endpoint); (2) investigate if a personalized perioperative blood pressure management is feasibly in multi-center studies, especially if the target values can be sufficiently achieved (secondary endpoint); (3) study the impact of personalized perioperative blood pressure management on the incidence of myocardial injury after non-cardiac surgery (MINS) (exploratory endpoint); (4) study the impact of personalized perioperative blood pressure management on the incidence of acute kidney injury within the first three postoperative days according to the KDIGO (Kidney Disease: Improving Global Outcomes) definition without oliguric criteria (exploratory endpoint).
This is a randomized trial (1) investigating whether continuous invasive arterial blood pressure monitoring using an arterial catheter reduces the area under a mean arterial pressure (MAP) of 65 mmHg within the first 15 minutes of anesthetic induction compared to intermittent arterial blood pressure monitoring using oscillometry in patients having major surgery under general anesthesia; and (2) investigating the effect of continuous invasive arterial blood pressure monitoring using an arterial catheter on cardiac output, stroke volume, and heart rate within the first 15 minutes of anesthetic induction compared to intermittent blood pressure monitoring using upper-arm cuff oscillometry in patients having major surgery under general anesthesia.
The induction of anaesthesia is one of the most critical situations for high-risk-patients undergoing interventions surgery. For several reasons, it is crucial to maintain adequate blood pressure and cardiac output during this phase. This retrospective cohort study aims to find out if the choice of the induction agent has a major impact on blood pressure and the use of catecholamines during the induction and the interventional procedure in patients undergoing interventional mitral valve repair.
Dietary salt raises blood pressure in certain individuals immediately after ingestion (acute salt sensitivity; ASS) while not affecting others. It is hypothesized that ASS is a risk factor for hypertension. However, no thresholds or diagnostic guideline is available for ASS. This study is the first aim in the main study (HIPO CAP DITSH Study) aimed at determining the threshold or blood pressure cut-offs for ASS upon ingesting dietary salt.
The study evaluates the acute effects of Helichrysum italicum on resting energy expenditure and substrate oxidation in humans. The resting energy expenditure and substrate oxidation will be measured by indirect calorimetry at baseline and after ingestion of either Helichrysum italicum infusion or hot water.
Orthognathic surgeries for maxillofacial deformities are commonly performed globally. However, they are associated with significant blood loss which can affect the surgical field and result in blood transfusion and its risks. We aim to review the different hypotensive anaesthetic practices for orthognathic surgeries, and their effects on intraoperative blood loss and transfusion requirements.
