Filter by:Postoperative delirium is an acute syndrome of mental deterioration characterized by acute onset and fluctuating course during the day. Very frequent delirium is a presage of other serious comorbidities i.e.: sepsis, acute kidney injury, circulatory and/or respiratory failure. A detailed knowledge of symptoms and early diagnose of delirium increase the chances of early therapy. To what extent the occurrence of postoperative delirium influences hospital therapy in the Cardiac Surgical Postoperative ICU in University Clinical Centre in Gdańsk is unknown so far.
Vaccination against SARS CoV-2 appears to be the best strategy today to control the COVID-19 pandemic. The first published studies with Pfizer, Moderna and Astra-Zeneca vaccines show very good vaccine protection in the general population and good short-term tolerance. The efficacy of these vaccines ranges from 62 to 95%, which is particularly remarkable, especially for mRNA vaccines. Nevertheless, these studies do not report the vaccine response in organ transplant patients. It is known that transplant patients have lower vaccine responses than immunocompetent patients due to some degree of immunosuppression. Therefore, the investigators are interested in evaluating the vaccine response of organ transplant recipients after vaccination against SARS- CoV-2. For non-responder patients, new strategies can be proposed: 3rd or 4th boost of vaccine or perfusion/injection of antiS monoclonal antibodies. These strategies must be evaluated.
The aim of the study is to develop a prognostic prediction model based on machine learning algorithms in patients affected by coronavirus disease 2019 (COVID-19), the prediction model will be capable to recognize patient with favorable prognosis or patient with poor prognosis by intelligent systems data analysis.
Vitamin D defiency during pregnancy is a major public health problem worldwide; In Spain, the average intake of vitamin D is lower than recommendations in an elevated percentage of the population, ranging from 50 to 95%, according to the Spanish Society of Community Nutrition (SENC). Recent research suggests that adverse pregnancy outcomes are associated to vitain D deficiency. Associated comorbidities are further complicated by the SARS-COV-2 Pandemic. Few studies have assessed the transmission of SARS-CoV-2 antibodies from mothers who have had the disease or have been vaccinated to their newborns, either at birth or during breastfeeding, or how vitamin D concentration influences the generation of such an immune response. The COVID-19 pandemic is a dynamic situation. Peer-reviewed studies in large study cohorts point to a clear relationship between prevalence and severity of COVID-19 and vitamin D deficiency.
The aim of this study is to evaluate pro-inflammatory cytokines as well as microvesicles during the course of SARS-CoV2 infection in the context of clinical parameters.
The determinants of the evolution to a severe form for COVID-19 pneumonia remain unclear. COVID-19 pneumonia is characterized by a hypoxemia with a possible rapid worsening and related resuscitation requirement. The monitoring of patients in hospital wards (excluding intensive care unit) is therefore both necessary and complicated given the contagious risks for health workers. The COVID 19 Respiratory Tele Monitoring (RTM COVID 19) research project is based on a comparison between usual nurse respiratory monitoring (4 to 6 time per day) of respiratory parameters (capillary oxygen saturation, respiratory rate, hearth rate) and a continuous monitoring of these respiratory parameters with continuous monitoring by a portable, wireless and stand-alone device. The main objective of this work is a more sensitive and earlier detection of respiratory degradation events in patients with COVID-19 pneumonia (capillary desaturation, increased respiratory rate) requiring the introduction of oxygen therapy, its increase or a resuscitation requirement with possible intensive care admission. A prospective, randomized, multicentre, comparative exposure study will be conducted with planned inclusion of 80 patients. This investigation will focus on patients with COVID-19 pneumonia hospitalized in dedicated medical wards of two University Hospitals in France. A randomization will be stratified by Hospital and adapted so that each Hospital provides the same number of subjects in each arms: - Control Respiratory Monitoring Group (40 patients) - Experimental Respiratory Monitoring Group (40 patients) The main criterion is respiratory degradation event, during a 4 days period after ward admission, which motivates a change in the therapeutic strategy defined by the presence of at least one of these elements: - Capillary saturation < 94% (regardless of oxygen intake) for at least 2 minutes. - And/or an increase in respiratory rate > 20/minute for at least 2 minutes. The modification of the therapeutic strategy is defined by: - Introduction of oxygen therapy for included patients without oxygen therapy or supplementation of oxygen therapy > 2 litres/minutes for included patients with oxygen therapy - And/or introduction of a high oxygen concentration mask - And/or Request an On-Site Opinion from a member of the resuscitation team. - And/or Transfer to intensive care or resuscitation unit - And/or Need for immediate resuscitation for life-threatening distress.
Microcirculatory dysfunction appears to play a key role in the development of organ failure leading to the death of patients with coronavirus disease 2019 (Covid-19). It is still uncertain today whether this damage is secondary to direct viral infection of endothelial cells or the consequence of the inappropriate inflammatory response induced by the infection. The analysis of endothelial and microcirculatory dysfunctions and glycocalyx degradation therefore appears to be necessary in the understanding of the pathophysiological mechanisms of Covid sepsis and could play a role in the evaluation of the efficacy of certain therapeutics which would aim at improving regional perfusion by decreasing microcirculatory dysfunction.However, the analysis of microcirculatory failure, endothelial dysfunction and glycocalyx degradation has so far only been evaluated in small cohorts, without quantitative analysis of microcirculatory perfusion
As part of the internal quality management (QM project), this retrospective cohort study examines the adherence to Standard Operating Procedures (SOP) of the COVID-19 patients treated since January 1st, 2020 to February 28th, 2021 in intensive care units of the Clinic for Anesthesiology m.S. operative intensive care medicine CCM / CVK.
In the context of the actual pandemia of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which requires a better diagnostic strategy for the management of patients. The study of volatile organic compounds (VOC) detected in exhaled air or in sweat, is an innovative research area for respiratory diseases. The analysis of VOC can be done either by the technique of the mass spectrometry which allows the identification of each VOC in the exhaled air or by the technique of electronic nose, simpler and faster, which provides an idea of the general profile of the VOC without identifying them. The VOC have shown their interest in some situations, such as diagnostic or prognostic tool in patients followed for thoracic tumorous pathology or bronchial or pulmonary vascular diseases. Moreover, it has recently been shown that properly trained dogs would be able to detect an olfactory signature of SARS-CoV-2 infection with a specificity greater than 90%; this olfactory signature corresponds to VOCs detectable by the flair of dogs (Nosaïs-Covid19 study). Validation of the diagnostic value of VOC analyzes by non-invasive and rapid methods (electronic nose analysis or mass spectrometry; detection by the scent of dogs) for the rapid detection and early diagnosis of a SARS-CoV-2 infection warrants the performance of this clinical study.
Several publications document the occurrence of prolonged or late-onset symptoms beyond 3 weeks after the first clinical manifestations of SARS-COV2 infection. These manifestations may be related to thromboembolic or inflammatory events or other mechanisms that are not yet well understood. The psychosomatic origin secondary to psychiatric disorders prior to the infection or in reaction to it is also to be evoked. The identification of the clinical manifestations observed, and their clinical and paraclinical evolution are essential to better understand the natural evolution of COVID-19, to specify the physiopathological mechanisms and to identify potential avenues of management for the patients. In addition, the impact of COVID-19 infection on primary care visits is not known. In general practice, these patients benefit from explorations and even diagnoses that may explain the persistence of symptoms (autoimmune diseases, thrombosis, somatoform disorders, hyperventilation syndrome, etc.). The objective of the COCO_Vi_LATE project is to carry out a cross-sectional study of patients presenting persistent and/or recurrent symptoms after an infection with SARS-COV-2 who will be compared to individuals with a short form of infection with COVID-19
