Introduction: We investigated the effect of postural changes on various cardiovascular parameters across gender. Twenty-eight healthy subjects (16 male, 12 female) were observed at rest (supine) and subjected to 3 interventions; head-down tilt (HDT), HDT with lower body negative pressure (HDT+ LBNP −30 mm Hg), head-up (HUT), each for 10 minutes separated by a recovery period. Methods: Measurements recorded heart rate (HR), standard deviation normal-to-normal intervals, root mean square...
Older adults following recovery from ischemic stroke have a higher incidence of orthostatic hypotension, syncope, and fall risk, which may be related to impaired autonomic responses limiting the ability maintain cerebral blood flow. Thus, we investigated cerebrovascular cardiovascular regulation in 23 ≥55 years age, 10 diagnosed with stroke, 13 age-matched healthy controls when sitting at rest upon standing compare differences variables ∼7 months (218 ± 41 days) poststroke. Arterial pressure...
Aims: The objective of our study was to assess the effects orthostatic challenge on coagulation system in patients with a history thromboembolic events and how they compared age-matched healthy subjects. Methods: Twenty-two histories ischemic stroke 22 subjects performed sit-to-stand test. Blood collected prior to- at end of- standing upright position for 6 minutes. Haemostatic profiling by determining thrombelastometry calibrated automated thrombogram values, indices thrombin generation,...
It is known that blood pressure regulation differs seasonally. unknown, however, how the cardiovascular system in patients with a stroke reacts to postural changes different seasons. The aim was therefore investigate temperatures cold and warm seasons influence reactions of haemodynamic mechanisms as well heart rate variability during sit-to-stand test control group. Hemodynamic responses were assessed both groups (5 min sitting followed by 5 standing) beat within two Systolic (SBP),...
Background Premenopausal women show a higher incidence of orthostatic hypotension than age-matched men, but there are limited data available on sex differences in cardiovascular responses to challenge healthy older persons. We investigated hemodynamic and autonomic males females. Materials methods Fourteen 10 men performed sit-to-stand test (5 min sitting followed by 5 standing). A Task Force ® Monitor continuously measured the following beat-to-beat parameters: heart rate, systolic blood...
Overweight and obesity are a burden of the modern world that requires urgent action. Prevention has proven to be efficient in fight against overweight obesity. As many children gain excessive weight at an early age, intervention during school years important. While daily physical activity (PA) is known have influence on prevention, importance healthy lifestyle, including dietary habits, should not underestimated. The aim this study was assess how combination PA healthy/unhealthy diet affect...
Abstract Background Neuroendocrine responses to orthostasis may be critical in the maintenance of mean arterial pressure healthy individuals. A greater reduction orthostatic tolerance with age relate modulation hormonal such as adrenomedullin and galanin. Thus, we investigated (i) whether galanin concentrations increase during challenge older subjects, (ii) are higher females compared males when seated challenge, (iii) postural changes plasma correlated levels either or males. Materials...
Purpose The retinal microcirculatory bed shares anatomical and physiological characteristics with the cerebral circulation. Static dynamic changes in blood vessels can mirror cardio‐ cerebrovascular events. aim of study was to underpin relevance analysis for stroke research. Methods 18 patients 16 age‐matched healthy control subjects were included present study. Retinal image acquisition done a Zeiss fundus camera FF 450plus. vessel using IFLEXIS software provided by VITO ( www.iflexis.com...
Introduction Pressure injuries are a common and significant concern in clinical practice, often serving as vital quality indicator. While (clinical) practice guidelines have been established to offer recommendations for mitigating hospital-acquired pressure injuries, adherence among stakeholders remains inconsistent. The subjective perceptions of stakeholders, such patients nurses, may impede ulcer prevention guidelines, potentially reducing the effectiveness these interventions. However,...
In a randomized crossover trial, we examined whether age plays role in the mean arterial pressure (MAP) response during vigorous flywheel exercise of varying load. We hypothesized that magnitude increase MAP would proportion to advancing age, thereby imposing significant challenge cardiovascular system. A total 30 participants both sexes (age range from 20–55 y, 37% women) underwent detailed medical examination, and their maximal oxygen uptake was determined. They performed squat (2 sets × 7...
Abstract Background Providing optimal care for critically ill patients is an extremely important but also highly demanding task, both emotionally and physically. The “ICU Support” team meeting concept aims to support intensive unit (ICU) teams by promoting interprofessional communication, peer support, patient safety providing a structure daily meetings. This protocol describes study explore the effectiveness of patient- staff-centered outcomes. Methods ICU Support will be implemented at...
