External Validation of the CHOD Risk Scale

COVID-19 PneumoniaPulmonary Embolism

Severe COVID-19 is associated with a hypercoagulable state, with a high risk of thrombotic phenomena such as pulmonary thromboembolism (PE). Its diagnostic suspicion is complicated, due to the overlap of symptoms of PE with those of COVID-19 itself. Therefore, it is essential to improve PE prediction to optimise the performance of confirmatory imaging tests such as thoracic CT angiography. Early diagnosis has relevant therapeutic implications, as it justifies starting anticoagulant treatment early, with a possible positive impact on the clinical evolution of these patients. The CHOD risk scale has recently been described: the acronym for C-reactive protein concentration, heart rate, oxygen saturation, and D-Dimer levels. Its initial description was carried out in a study in a single hospital centre. proving to be an easy-to-apply tool, useful for predicting the appearance of PE in patients hospitalized for COVID-19. The objective of this study is to carry out an external validation of this scale in patients hospitalized for COVID-19 pneumonia, through an observational, cross-sectional, multicenter, real-life study in patients hospitalized for severe COVID-19 pneumonia, confirmed by objective methods, and showing high D-dimer values. Imaging tests with CT angiography will be performed in patients with elevated D-Dimer, following international clinical practice regulations. Given that they will be consecutive patients, CT angiography will be performed in all patients regardless of the patient's clinical probability of PE as long as they meet the inclusion criteria and none of the exclusion criteria. To calculate the PE predictive power of the CHOD scale in the validation cohort, a methodology similar to that used in the construction cohort will be used, that is, the use of a ROC curve. Taking into account that a similar predictive value (with a maximum error of 5%) between the CHOD scale in the construction cohort and that of this study (validation cohort) will be considered as an adequate external validation, and taking into account a statistical power of 80%, an alpha error of 5% and a maximum loss of patients of 15%, the required sample size is 245 patients. Since 7 centres initially participate, each of which will have to contribute 35 valid consecutive patients for the analysis.

Dynamics of Markers of Infection and Inflammation in Hospitalized Coronavirus Disease 2019 (COVID-19)...

COVID-19 Respiratory Infection

Patients requiring admission to the hospital due to a moderate and severe COVID-19 infection may differ in their ability to respond to viral infection and to eliminate viral load. Several comorbidities and interventions like antivirotic or antiinflammatory treatment may also modify expected patients response and decrease of viral load. In this observational study, evolution of selected inflammatory markers, indicators of severity of infection and patient characteristics will be followed and recorded in hospitalized patients with COVID-19.

Depression and Anxiety in Long Term Coronavirus Disease COVID-19

Covid19Depression1 more

Background : Depression and Anxiety are linked to COVID (Coronavirus Disease)-19 long-term impact through several mechanisms. The possible way is the alteration of neurotransmitter regulation from the interaction of severe acute respiratory syndrome -Coronavirus-2 (SARS-COV2) with Angiotensin-Converting Enzyme 2 (ACE2) receptor, and Dopa Decarboxylase (DDC), an enzyme that associated with the production of dopamine, serotonin, and other neurotransmitters. However, some arguments exist that depression and anxiety occur naturally due to external stressors, as the impact of public health measures, and not associated with physiological changes due to viral infection. Objective: This study aims to identify whether the patient discharged after COVID 19 treatment has significant changes in serotonin and dopamine level which might induce depression and anxiety internally and, To distinguish external etiologies that might induce depression and anxiety such as social isolation and stress due to public health restriction. Method: A prospective longitudinal study of people with the interest exposure is COVID 19 and the primary outcome is Depression, Anxiety, and Neurotransmitter level Hypothesis: People with a previous infection of COVID 19 have a significant difference in neurotransmitter level over time and compared to non exposed group and a higher prevalence of anxiety and depression.

Contribution of a Prone Team in Intensive Care During the Covid-19 Epidemic

Sars-CoV2

SARS-CoV-2 induced by COVID 19, involved the hospitalization of 101,932 patients in France, including 4,007 in intensive care (source: Santé Publique France). Alsace was one of the most affected regions on the metropolitan territory with a large number of patients hospitalized at the University Hospital of Strasbourg. In view of the seriousness of the epidemic and the rapid arrival of new patients requiring mechanical ventilation, 3 new intensive care units have been created on the NHC site alone, making it possible to accommodate a maximum of 111 patients (compared to 52 during normal periods).

Factors Associated With Adherence to Hygiene-related Behaviors and Viral Mitigation Protocols During...

Adherence to WHO-advised Hygiene-related BehaviorAdherence to Viral Mitigation Protocols

Study description: The preset study seeks to investigate factors associated with of hygiene-related behaviors and adherence to viral mitigation protocols during the COVID-19 pandemic. In particular, factors associated with of adherence to WHO-advised hygiene-related behaviors and adherence to governmental mitigation protocols are investigations. The aim of the project is to: Inform the policymakers, the general public, scientists, and health practitioners about the cognitive, behavioral, emotional, motivational, and trait components underlying hygiene-related behaviors and adherence. Help policymakers better understand adherence and the factors it is associated with, providing empirical grounds to advance societies battle against the COVID-19-virus from an epidemiological perspective by promoting factors that increase adherence. Hypothesis/Research questions Hypothesis 1: Risk perception, altruism and governmental trust will significantly be associated with both adherence and hygiene-related behavior, with increased risk perception, altruism, and governmental trust associated with higher rates of adherence and hygiene-related behavior. The personality traits conscientiousness and agreeableness will significantly be associated with both adherence and hygiene related behavior, with increased conscientiousness, and agreeableness associated with higher rates of adherence and hygiene-related behavior. Furthermore, beliefs about pandemic protocol efficacy and beliefs about collective mitigation behavior (i.e., "it is only useful to follow transmission protocols if everyone else does") will be associated with adherence to viral mitigation protocols and hygiene-related behaviors. Research Question 1: Is there a difference between the use of various platforms to obtain information about COVID with regards to adherence to viral mitigation protocols and hygiene-related behaviors? Research Question 2: To what extend are different sources of obtaining information associated with adherence to hygiene-related behavior and adherence to viral mitigation protocols? Research Question 3: To what extent are different personality traits (measured with the Short Big Five Inventory-10 (BFI-10)) associated with adherence to viral mitigation protocols and hygiene-related behaviors?

Difficulties in Emotion-regulation and Interpersonal Problems During and After the COVID-19 Pandemic...

AnxietyDepression2 more

Central indicators of psychological functioning such as difficulties in emotion regulation and habitual problems in one's relating to others are likely to have been substantially impacted by the COVID-19 amelioration measures of societal lock-down and physical (ne social) distancing. In turn, as these amelioration measures have been relaxed, that impact will presumably be reduced, gradually returning these factors to pre-crisis levels. Also, these factors are likely to predict mental health outcomes such as symptoms of depression and anxiety throughout the pandemic and beyond, so that levels of emotion regulation difficulties and interpersonal problems early on will predict later symptom status. Similarly reductions in such difficulties during the various phases of the outbreak will be associated with a concurrent reduction in psychological symptoms and reduced symptom levels at later stages.

DepressionGeneralized Anxiety1 more

Study description: The present study seeks to investigate the impact of various sources of information on psychopathology, and specifically health anxiety, depression, and general anxiety, during the COVID-19 pandemic. The study will investigate the divergent impact of various information sources on these psychopathological symptoms during the pandemic. Hypotheses and research questions: Hypothesis 1: Media consumption across all information sources will significantly be associated with depression and anxiety symptoms, with increased media consumption in general associated with higher levels of health anxiety, depression, and general anxiety. Hypothesis 2: Using social media and online interactive platforms to obtain news about the pandemic in comparison to using traditional media (e.g., TV, radio, and newspapers) will be associated with higher levels of health anxiety, depression, and general anxiety. Actively staying away from information will further significantly be associated with higher levels of higher levels of health anxiety, depression, and general anxiety. Research Question 1: Is there a differential effect among different information sources on health anxiety, depression and general anxiety? To what extend and how are different information sources related to symptoms of health anxiety, depression, and general anxiety. Exploratory: Additionally, we will exploratory investigate to what extent the amount of use of different information sources impact health anxiety, depression, and general anxiety. We will also examine effect sizes with part correlations, to investigate information sources with the most and least detrimental impact on health anxiety, depression, and general anxiety. Furthermore, we will report which information platforms participants reported as most useful with regards to information concerning how to best deal with the pandemic.
