Abstract:

Background and hypothesis: Standard pharmacological treatment for heart failure improves cardiac remodelling and survival in the setting of chronic heart failure, but is suboptimal in cases of acute heart failure (AHF). Peripartum cardiomyopathy (PPCM), de-novo hypotension (often due to haemorrhagic shock), and Takotsubo cardiomyopathy (TC) are conditions which have acute onset of heart failure, and often present with high mortality rates. In patients treated for these pathologies, a variation in the heart rate is observed and could potentially be used as a target to improve the treatment of A

Abstract:

Abstract Several studies have shown that altered cardiovascular autonomic regulation is associated with hypertension, diabetes, aging, angiographic severity of coronary artery disease (CAD), and increased mortality after acute myocardial infarction (AMI). The purpose of this study was to assess the temporal changes and prognostic significance of various measures of heart rate (HR) behaviour and their possible associations to coronary risk variables, and the progression of CAD in different populations. This study comprised five patient populations. The first consisted of 305 patients with rece

Abstract:

Slow and deep breathing (SDB) has long been regarded as a nonpharmacological method for dealing with several physiological and emotional imbalances, and widely used for relaxation purposes. There is, however, limited understanding of the putative mechanisms by which SDB acutely impacts the cardiovascular and autonomic systems to elicit chronic adaptations. The present thesis explored how the manipulation of breathing pattern and intrathoracic pressure during SDB could further the understanding of the regulatory mechanisms that underpin the acute cardiovascular response to SDB.

Abstract:

Abstract There is a need to identify patients with an increased risk of dying after acute myocardial infarction (AMI), because sudden cardiac death (SCD) and potentially fatal ventricular tachyarrhythmias can be prevented by an implantable cardioverter-defibrillator, or in some cases, with aggressively optimized drug or revascularization therapy. The present study was designed to study the predictive power of non-invasive risk markers and all-cause, cardiac and arrhythmic mortality in 700 consecutive post-AMI patients discharged alive with optimal medication according to contemporary guideline

Abstract:

Background: Consistent with the ‘reactivity hypothesis’, monitoring autonomic responses to exercise might be of value in clinical and high-performance settings. Post-exercise autonomic recovery may be non-invasively assessed using heart rate variability indices of cardiac parasympathetic neural activity (cPNA-HRV) and systolic time intervals reflecting cardiac sympathetic neural activity (cSNA-STI). However, the dose of exercise may confound autonomic recovery, independent of underlying pathology or function. This thesis investigated how these indices respond to variations of the factors const

Abstract:

Mechanical ventilation (MV) is a life-saving therapy in acute respiratory distress syndrome (ARDS), a condition that affects 3000 patients/year in Sweden with a mortality rate of about 40%. However, MV may induce or worsen lung injury causing “ventilator-induced lung injury (VILI)”. From a mechanical perspective strain (deformation, or relative change in lung volume) and stress (tension) have been postulated as main determinants of VILI. High respiratory rate is potentially another factor that may exacerbate VILI by amplifying the total energy transmitted to the lungs during MV. In this thesis

The atypical chemokine receptor ACKR2 promotes resolution of acute inflammation by operating as a scavenger receptor for inflammatory CC chemokines in several experimental models of inflammatory disorders, however its role in the brain remains unclear. Based on our previous reports of increased expression of inflammatory chemokines and their corresponding receptors following traumatic brain injury (TBI), we hypothesised that ACKR2 modulates neuroinflammation following brain trauma and that its deletion exacerbates cellular inflammation and chemokine production.

Serious illness in childhood is a rare occurrence, but accounts for 20% of childhood deaths. Early recognition and treatment of serious illness is vital if the child is to recover without long-term disability. It is known that vital signs such as heart rate, respiratory rate, temperature, and oxygen saturation can be used to identify children who are at high risk of serious illness. This thesis presents research into the development of a vital signs monitor, designed for use in the initial assessment of unwell children at their first point of contact with a medical practitioner.

Abstract:

The major components of the tracheal system of insects are an extension of the exoskeleton, and the size of the exoskeleton is fixed in the adult stage, so any increase in metabolic demand that may accompany reproduction must be met by a relatively unaltered tracheal system that the female set in place at ecdysis, when entering adulthood. Acute hypoxia tends to elicit an increase in ventilation in insects, and here, I observe increased interburst VCO2 release, and a tendency towards a more continuous gas exchange pattern being preferred over discontinuous gas exchange when Blaptica dubia and E

Advances in medical technology have altered the need for certain types of surgery to be performed in traditional inpatient hospital settings. Less invasive surgical procedures allow a growing number of medical treatments to take place on an outpatient basis. Hospitals face growing competition from ambulatory surgery centers (ASCs). The competitive threats posed by ASCs are important, given that inpatient surgery has been the cornerstone of hospital services for over a century.

Abstract:

The scientific novelty of the study A large number of reports have demonstrated that depressed heart rate variability after myocardial infarction (MI), left ventricular dysfunction and arrhythmias are powerful predictors of mortality. Nevertheless there is a lack of detailed assessment of heart rate variability in the acute period of MI, especially during the first 24 hours, from long-term (24-h) recordings, and the value of different parameters of heart rate variability in predicting dangerous complications of MI was not fully evaluated. The indications of complex and constant monitoring of

Abstract:

Introduction: Ventricular arrhythmias (VAs) are common after an acute coronary syndrome (ACS) and are associated with worse clinical outcomes. However, little is known about recent trends in their occurrence, their association with serum glucose levels, and their psychological impact in ACS setting. Methods: We examined 25-year (1986-2011) trends in the incidence rates (IRs) and hospital case-fatality rates (CFRs) of VAs, and the association between serum glucose levels and VAs in patients with an acute myocardial infarction (AMI) in the Worcester Heart Attack Study. Lastly, we examined the re

Les cardiopathies ischémiques sont une cause majeure de mortalité cardiovasculaire pouvantaboutir à la mort subite par fibrillation ventriculaire (FV). Un des objectifs thérapeutiqueschez les coronariens est de diminuer la demande en O2 par réduction de la fréquencecardiaque (RFC). Plusieurs médicaments dont les bêta-bloquants et inhibiteurs calciquesrépondent à cet objectif, mais peuvent être responsable d’altération de la contractilitécardiaque et d’effets secondaires limitant leur utilisation.

Abstract:

Background Previous measurements of preventable death in hospital do not account for the uncertainty of preventability ratings. Objective To determine the proportion of deaths in hospital that a have high probability of being prevented with high quality care. Methods We created summaries for every death at a tertiary care hospital over 4-months. Four reviewers assigned preventability ratings to each death and latent class analysis was used to classify deaths into high and low preventability categories. Results There were 480 decedents with mean age of 73.9. Inter-rater reliability was p

Abstract:

Pesquisas com células tronco têm demonstrado que essa alternativa terapêutica tem grande potencial em diversas patologias. Contudo, muito ainda precisa ser elucidado quanto aos mecanismos de ação, dose e melhores vias de aplicação, para que essa alternativa terapêutica seja efetivamente incorporada às outras. Neste contexto, a via de aplicação se torna crucial na efetividade do tratamento. O objetivo do presente estudo foi avaliar no modelo de necrose tubular aguda (NTA) induzido pelo glicerol o potencial de migração das células tronco mesenquimais derivadas de polpa dentária humana, utilizand

Abstract:

INTRODUÇÃO: Em pacientes transplantados renais, a paratireoidectomia está associada à piora aguda da função renal. Os efeitos agudos e crônicos da paratireoidectomia sobre a filtração glomerular foram pouco estudados em Hiperparatireoidismo Primário (HPTP). MÉTODO E CASUÍSTICA: Neste estudo retrospectivo de coorte, foram estudados 494 pacientes submetidos a paratireoidectomia por HPTP, entre os anos de 2007 e 2016. Variações agudas da creatinina foram aferidas diariamente na internação, até o 4o pós-operatório, sendo classificados conforme os critérios de KDIGO para IRA. Dados bioquímicos incl
